Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

A dispensing assembly for dispensing lotion according to an embodiment of the present invention is described below with reference to fig. 1-2.

As shown in fig. 1 and 2, a dispensing assembly for dispensing a lotion according to an embodiment of the first aspect of the present invention comprises: amain housing 1. Themain pipe shell 1 is provided with a liquid inlet end and a liquid outlet end, water is suitable for flowing into themain pipe shell 1 through the liquid inlet end and flowing out of the liquid outlet end, the side wall of themain pipe shell 1 is provided with anair inlet 102 and asuction inlet 101, theair inlet 102 and thesuction inlet 101 can be arranged at intervals, thesuction inlet 101 and theair inlet 102 are both positioned between the liquid inlet end and the liquid outlet end, lotion is suitable for flowing into themain pipe shell 1 through thesuction inlet 101, gas is suitable for flowing into themain pipe shell 1 through theair inlet 102, and the gas entering from theair inlet 102 can be air.

The negative pressure generated by the flow of water in themain pipe case 1 can be used as a driving force to suck lotion into themain pipe case 1 through thesuction port 101, for example, themain pipe case 1 can be a venturi tube. The lotion can be sucked into themain pipe casing 1 through thesuction port 101 by the pumping action of the pump using the pump or the like as power. Alternatively, when themain tube housing 1 is a venturi tube, the lotion is sucked into themain tube housing 1 through thesuction port 101 by the negative pressure generated by the flow of the water flow in themain tube housing 1 and the suction action of the pump.

The negative pressure created by the flow of water in themain vessel shell 1 can be used as a driving force to cause gas to be drawn into themain vessel shell 1 through thegas inlet 102, for example themain vessel shell 1 can be a venturi tube. It is also possible to use a pump, a fan, or the like as power, and to cause gas to be sucked into the maintubular housing 1 through thegas inlet 102 by the suction action of the pump or the fan. Alternatively, when themain tube housing 1 is a venturi tube, the gas is sucked into themain tube housing 1 through thegas inlet 102 by using both the negative pressure generated by the flow of the water flow in themain tube housing 1 and the suction action of the pump or the blower.

Therefore, when the putting assembly is used for the putting device of the washing machine, the putting device can put the washing agent into the washing barrel of the washing machine. In the process of putting the lotion by using the putting component, water enters themain pipe shell 1 through the liquid inlet end of themain pipe shell 1, the lotion sucked by thesuction inlet 101 and the gas sucked by thegas inlet 102 also enter themain pipe shell 1, and the gas, the water and the lotion are mixed in themain pipe shell 1, so that the lotion is fully dissolved, and the fully dissolved lotion flows into a washing barrel of the washing machine through the liquid outlet end. Therefore, after the lotion enters themain pipe shell 1, the lotion is dissolved in the water flow in themain pipe shell 1, and at the same time, because the air enters themain pipe shell 1, the dissolution of the lotion can be promoted through the sufficient mixing of the air, the water and the lotion, for example, when the lotion is a detergent, the foaming effect of the lotion can be improved, the foam after foaming is more fine, and the cleaning effect is improved.

In the process of using the dosing assembly to dose the lotion, the lotion can be supplied first and then the gas can be supplied, the gas can be supplied first and then the lotion can be supplied, or the lotion and the gas can be alternately supplied. The water flow in themain pipe casing 1 may be opened before, after, or during the administration of the gas and the detergent, or the water flow in themain pipe casing 1 may be alternated with the administration of the gas and the detergent. Wherein, the rivers in being responsible forshell 1 are opened before the input of gas and lotion, and lotion and gas can just contact rivers from the beginning like this, and make lotion not too much accumulation in the pipeline for lotion dissolves abundant, even, reduces and remains the caking risk, thereby reduces the pipeline and blocks up the risk.

The lotion comprises detergent, softener, disinfectant and the like, namely the lotion generally refers to additives for putting in a laundry process. When the washing machine is in a washing stage, the detergent can enter themain pipe shell 1 through thesuction inlet 101, and the gas can enter themain pipe shell 1 through thegas inlet 102, so that the detergent can be fully dissolved, the foaming effect of the detergent is improved, and the cleaning effect is improved; when the washing machine is in a rinsing stage, the softener and the disinfectant can enter themain pipe shell 1 through thesuction inlet 101, and the gas can enter themain pipe shell 1 through thegas inlet 102, so that the softener and the disinfectant can be fully dissolved, the hand feeling is improved, and the disinfection rate is improved. After the washing and rinsing phases of the washing machine, a water flow may be sucked through thesuction port 101 to flush thesuction port 101 after the corresponding detergent is put in.

Because the dispensing assembly can fully dissolve the lotion in water, the lotion can play a more sufficient role in the washing process, for example, the cleaning effect can be improved, the hand feeling can be improved, and the disinfection rate can be improved.

Alternatively, theair inlet 102 and thesuction port 101 are disposed adjacently, and by disposing theair inlet 102 and thesuction port 101 adjacently, the lotion and the air can be contacted and sufficiently mixed in a short time after entering themain casing 1, so that the dissolving effect and the foaming effect of the lotion can be further improved.

In addition, because gas enters themain pipe shell 1 through thegas inlet 102, the lotion enters themain pipe shell 1 through thesuction inlet 101, thegas inlet 102 and thesuction inlet 101 are independent of each other, and the lotion and the gas enter themain pipe shell 1 through independent channels respectively, so that the introduction of the lotion and the gas is not influenced by each other, the introduction of the gas cannot be influenced due to the agglomeration and the condensation of the lotion under the influence of the air under the condition of no flushing, and the risk of gas path blockage is reduced.

According to the dispensing assembly for dispensing the lotion, theair inlet 102 is arranged, so that air is introduced into themain pipe shell 1 through theair inlet 102 in the process that the lotion flows into themain pipe shell 1 through thesuction inlet 101, the lotion can be fully dissolved in water flow through the disturbance effect of the air, the foaming effect of the lotion can be improved, the cleaning effect can be improved, the caking risk of the residual lotion can be reduced, and the blocking risk of a pipeline can be reduced. And, lotion and gas are respectively by independent passageway enteringmain tube shell 1 for the letting in of lotion and gas does not influence each other, makes under the condition that does not wash, can not influence gaseous letting in because of the caking of lotion under the influence of air condenses, reduces the jam risk of gas circuit.

According to some embodiments of the present invention, referring to fig. 1 and 2, themain pipe shell 1 is a venturi tube, themain pipe shell 1 includes afirst pipe segment 11, asecond pipe segment 12 and athird pipe segment 13 which are connected in sequence, the flow area of thesecond pipe segment 12 is smaller than the flow area of thefirst pipe segment 11 and smaller than the flow area of thethird pipe segment 13, the liquid inlet end is located in thefirst pipe segment 11, the liquid outlet end is located in thethird pipe segment 13, thesuction inlet 101 is formed in thefirst pipe segment 11 or thesecond pipe segment 12, and thegas inlet 102 is formed in thefirst pipe segment 11 or thesecond pipe segment 12. By arranging themain pipe shell 1 as a venturi tube, water flows into thefirst pipe section 11 through the liquid inlet end and then flows through thesecond pipe section 12 and thethird pipe section 13 in sequence, and as the flow area of thesecond pipe section 12 is small, large negative pressure can be generated in the process that water flows through thesecond pipe section 12.

When thesuction port 101 is formed in thefirst pipe segment 11 or thesecond pipe segment 12, the above-described negative pressure effect can be utilized to suck the lotion into themain pipe housing 1 through thesuction port 101. When thegas inlet 102 is formed in thefirst pipe segment 11 or thesecond pipe segment 12, the above-described negative pressure effect can be utilized, so that gas is sucked into themain pipe casing 1 through thegas inlet 102. Wherein, both the lotion and the gas can enter themain pipe shell 1 only through the negative pressure; alternatively, the gas enters themain casing 1 by the above-mentioned negative pressure, and the lotion enters themain casing 1 mainly by the pumping action of the pump.

In addition, in the process of mixing the detergent, the gas and the water flow in thesecond pipe section 12, since the flow area of thesecond pipe section 12 is small, the water flow speed is increased, and the turbulent motion effect is good, the mixing effect is good, the dissolving effect and the foaming effect of the detergent can be further improved, and the cleaning effect can be improved.

According to some alternative embodiments of the present invention, referring to fig. 1, thesuction inlet 101 and thegas inlet 102 are both formed in thefirst pipe section 11. Therefore, the lotion enters thefirst pipe section 11 through thesuction inlet 101 and the gas enters thefirst pipe section 11 through thegas inlet 102, the gas and the lotion can be preliminarily mixed with water flow in thefirst pipe section 11, then the lotion and the gas flow to thesecond pipe section 12 along with the water flow, so that before the gas and the lotion flow to thesecond pipe section 12, the gas and the lotion can be premixed with the water flow in thefirst pipe section 11, when the lotion and the gas flow to thesecond pipe section 12 along with the water flow, the flow area of thesecond pipe section 12 is reduced, the water flow speed is increased, the turbulent flow effect is good, the mixing effect is enhanced, more fine foams are generated, the Reynolds number can reach more than 10000, the dissolving effect and the foaming effect of the lotion can be better improved, the cleaning effect is better improved, and more than 10% of the lotion can be saved under the same cleaning and decontamination requirements.

According to some alternative embodiments of the invention, referring to fig. 2, asuction opening 101 is formed in thefirst pipe section 11, and lotion is sucked into thefirst pipe section 11 through thesuction opening 101 and then flows into thesecond pipe section 12 with the water flow, and the lotion can be premixed with the water flow before flowing into thesecond pipe section 12. Theair inlet 102 is formed in thesecond pipe section 12, and the air enters thesecond pipe section 12 from theair inlet 102, and the lotion flowing into thesecond pipe section 12 along with the water flow is mixed with the air in thesecond pipe section 12, and meanwhile, because the flow area of thesecond pipe section 12 is reduced, the water flow speed is increased, the turbulent motion effect is good, so that the mixing effect is enhanced, more fine foams are generated, the dissolving effect and the foaming effect of the lotion can be better improved, and the cleaning effect is better improved.

According to some embodiments of the invention, referring to fig. 1 and 2, an inner tube 3 is provided within themain vessel shell 1, the inner tube 3 having an inlet adjacent the inlet end and anoutlet 30, water being adapted to flow into the inner tube 3 through the inlet and out of theoutlet 30 into themain vessel shell 1. Wherein, water can directly flow into the inner tube 3 through the inlet, and water also can flow into the liquid inlet end firstly and then flows into the inner tube 3 through the inlet of the inner tube 3. From this, through being equipped with inner tube 3 in being responsible forshell 1, and make rivers flow in inner tube 3, because the cross-sectional area of inner tube 3 can be less thanmain pipe shell 1's cross-sectional area, thereby can increase the velocity of flow of rivers, the velocity of flow can increase after the inner tube 3 is flowed through to the rivers, rivers can be with higher velocity of flow blowout from theexport 30 of inner tube 3, strengthen the impact effect of rivers, make water, lotion and gas three intensive mixing, the foaming, and then can further improve the dissolution effect and the foaming effect of lotion, improve the washing effect.

According to some alternative embodiments of the present invention, referring to fig. 1 and 2, aflow space 301 is defined between an outer side wall of the inner pipe 3 and an inner side wall of themain pipe casing 1, thesuction port 101 is formed on an outer side wall of theflow space 301, and thegas inlet 102 is formed on an outer side wall of theflow space 301 or thegas inlet 102 is located downstream of the flow space 301 (the term "thegas inlet 102 is located downstream of theflow space 301" means that thegas inlet 102 is located downstream outside theentire flow space 301, with respect to the flow direction of the water flow). Therefore, when thesuction port 101 and thegas inlet 102 are both formed on the outer side wall of theflow space 301, the lotion can firstly enter theflow space 301 through thesuction port 101 and thegas inlet 102, so that the lotion and the gas are fully mixed before contacting with the water flow, and the lotion and the gas are fully mixed in theflow space 301 and then contact with the water flow, thereby further improving the dissolution effect and the foaming efficiency of the lotion and further improving the cleaning effect; when thesuction port 101 is formed on the outer side wall of theflow space 301 and theair inlet 102 is located at the downstream of theflow space 301, the lotion enters theflow space 301 from thesuction port 101 and flows to the downstream part of themain casing 1 located in theflow space 301, and is mixed with the water flow and the air entering from theair inlet 102, so that the water, the lotion and the air are mixed and foamed, and further, the dissolving effect and the foaming effect of the lotion can be improved, and the cleaning effect is improved.

Optionally, the cross-section of theflow space 301 is annular extending around the inner tube 3. Thereby, theflow space 301 is made large, so that the lotion and the gas can be sufficiently mixed in theflow space 301.

In some alternative embodiments of the present invention, referring to fig. 1 and 2, the inner tube 3 comprises amain body section 31 and acompression section 32 connected together, thecompression section 32 may be a tube section with a uniform inner diameter, the inlet is formed in themain body section 31, theoutlet 30 is formed in thecompression section 32, and the flow area of thecompression section 32 is smaller than that of themain body section 31. From this, at the in-process of rivers flow through inner tube 3, rivers pass through the in-process ofcompression section 32, and rivers can further be accelerated to make rivers can be fromexport 30 blowout with higher speed, further increase the impact force of rivers, further make water, lotion and gas intensive mixing, foaming, and then can further improve the dissolving effect and the foaming effect of lotion, improve the washing effect.

Alternatively, referring to fig. 1, thesuction port 101 and theintake port 102 are both located upstream of the compression section 32 (the phrase "thesuction port 101 and theintake port 102 are both located upstream of thecompression section 32" means that thesuction port 101 and theintake port 102 are both located upstream of theentire compression section 32, with respect to the flow direction of the water flow). Thereby, a certain distance is provided between thesuction port 101 and thegas inlet 102 and theoutlet 30 of the inner tube 3, so that the lotion and the gas can be mixed with sufficient space and time before the lotion and the gas contact the water flow after the lotion and the gas enter theflow space 301 through thesuction port 101 and thegas inlet 102, respectively.

In some alternative embodiments of the present invention, referring to fig. 1, the inner tube 3 includes a connecting section 33, the connecting section 33 connects themain body section 31 and thecompression section 32, an outer side wall of the connecting section 33 extends obliquely toward a direction adjacent to a central axis of themain tube shell 1 in a direction from themain body section 31 to thecompression section 32, a minimum flow area of the connecting section 33 is not smaller than a flow area of thecompression section 32, and thesuction port 101 and theintake port 102 are both located upstream of the connecting section 33 (the "suction port 101 and theintake port 102 are both located upstream of the connecting section 33" means that thesuction port 101 and theintake port 102 are both located upstream outside the entire connecting section 33, the upstream being with respect to a flow direction of the water flow). Thus, the change in the flow area between themain body segment 31 and thecompression segment 32 is alleviated by the provided connection segment 33, and the flow loss can be reduced. Also, since thesuction inlet 101 and thegas inlet 102 are both located upstream of the connection section 33, the distance between thesuction inlet 101 and thegas inlet 102 and theoutlet 30 of the inner tube 3 can be further increased, so that the lotion and the gas can be more sufficiently mixed in space and time before the lotion and the gas contact the water flow. In addition, after the lotion sucked by thesuction port 101 and the gas sucked by thegas inlet 102 enter theflow space 301, the lotion and the gas can more smoothly flow forward to contact with the water flow by the guiding action of the outer side wall of the connecting section 33.

According to some alternative embodiments of the present invention, referring to fig. 1 and 2, themain pipe shell 1 is a venturi tube, themain pipe shell 1 includes afirst pipe segment 11, asecond pipe segment 12 and athird pipe segment 13 which are connected in sequence, the flow area of thesecond pipe segment 12 is smaller than that of thefirst pipe segment 11 and smaller than that of thethird pipe segment 13, the liquid inlet end is located in thefirst pipe segment 11, the liquid outlet end is located in thethird pipe segment 13, the inner pipe 3 is arranged in thefirst pipe segment 11, aflow space 301 is defined between the outer side wall of the inner pipe 3 and the inner side wall of thefirst pipe segment 11, theoutlet 30 is adjacent to thesecond pipe segment 12, and thegas inlet 102 is formed on the outer side wall of theflow space 301 or thegas inlet 102 is formed.
