According to what is shown in fig. 1 to 9, the device body 100 further includes:
The connector 151 extends at least partially from within the device body 100 through or to the holding space 150, the connector 151 being arranged for connection of the liquid source 200 to establish fluid communication of the liquid source 200 with the first reservoir of the device body 100 and/or the liquid holding element 23 to enable the liquid source 200 to replenish the device body 100 with a liquid matrix. The joint 151 is basically configured to be a hollow tubular shape. A sealing ring 152 is arranged on the joint 151, thereby providing a seal between the joint 151 after insertion into the liquid source 200.
According to the embodiment shown in fig. 1 to 9, the first tubular element 21 has a connecting portion 28 extending towards the second side 140, and one end of the joint 151 is wrapped around and joined to the connecting portion 28, whereby the joint 151 is fixedly connected to the first tubular element 21 via the connecting portion 28 and in communication with the first reservoir and/or the liquid retaining element 23.

According to what is shown in fig. 1 to 9, the tab 151 is aligned with at least part of the liquid guiding member 30 in the width direction of the device body 100. And, the junction 151 is in fluid communication with the first reservoir and/or a side of the liquid retaining member 23 adjacent the second sealing member 51.
As shown in fig. 4 to 7, the joint 151 is further disposed therein:
a first capillary element 154 is located within the junction 151. The first capillary element 154 extends at least partially into the first reservoir, or the first capillary element 154 at least partially abuts or contacts the liquid retaining element 23.
In some embodiments, the first capillary element 154 comprises or is made of flexible fibers such as cotton fibers, nonwoven fabrics, or sponges. In use, when the liquid matrix of the liquid source 200 flows to the first liquid storage chamber and/or the liquid retaining element 23 via the connector 151, the first capillary element 154 can absorb and buffer the liquid matrix by capillary action to adjust the flow rate of the liquid matrix from the liquid source 200 to the first liquid storage chamber and/or the liquid retaining element 23, thereby preventing the liquid matrix from flowing too fast to cause liquid leakage and releasing the liquid matrix when the liquid matrix flows slowly to ensure the supply rate. And, because of the air pressure difference between the first liquid storage chamber and the second liquid storage chamber 214 of the liquid source 200 during the suction, the first capillary element 154 supplements the air in the first liquid storage chamber to the second liquid storage chamber 214 of the liquid source 200 during or after the suction of the device main body 100, and the air passes through the micro-holes of the first capillary element 154 to generate bubbles in the liquid source 200, thereby facilitating the liquid medium in the second liquid storage chamber 214 of the liquid source 200 to pass from the liquid to the first liquid storage chamber.
According to what is shown in fig. 1 to 9, in order to facilitate the passage of air in the first reservoir through the first capillary element 154, a recess or air groove 29 is arranged on one side of the liquid retaining element 23, which recess or air groove extends in the longitudinal direction. An air channel is defined by the recess or air groove 29 between the liquid retaining member 23 and the inner surface of the first tubular member 21 when assembled, and at least a portion of the first capillary member 154 is in opposing and communication with the recess or air groove 29 when assembled. So that when the liquid source 200 is coupled to the device body 100, air in the first reservoir enters the second reservoir 214 via the grooves or air slots 29 and the micro-holes in the first capillary element 154. In some embodiments, the upper end of the groove or air channel 29 is in communication with the gap between the liquid retaining element 23 and the first sealing element 24, and the lower end of the air channel defined by the groove or air channel 29 is in communication with the first capillary element 154. Or along the longitudinal direction of the device body, the air channel defined by the groove or air channel 29 is arranged to extend between the first capillary element 154 and the gap of the liquid retaining element 23 and the first sealing element 24.
According to what is shown in fig. 1 to 9, the liquid source 200 comprises:
An outer body 210 defining a housing or outer surface of the liquid source 200, the outer body 210 being defined by a first housing portion 211 and a second housing portion 212;
a flexible sealing element 213 at least partially positioned between the first housing portion 211 and the second housing portion 212 to provide a seal therebetween;
a second reservoir 214 for storing a liquid matrix;
the second housing portion 212 defines a socket 220, and when the liquid source 200 is coupled to the device body 100, the connector 151 is inserted into the socket 220, thereby establishing liquid communication between the second liquid storage chamber 214 of the liquid source 200 and the first liquid storage chamber of the device body 100, and further replenishing or flowing the liquid matrix in the second liquid storage chamber 214 to the first liquid storage chamber of the device body 100.
As shown in fig. 1 to 9, the liquid source 200 further includes:
A liquid transfer mechanism 230 is movably disposed within the liquid source 200 and is movable between a first position and a second position. In fig. 4 and 6, a schematic view of the liquid transfer mechanism 230 is shown in a first position in which the liquid transfer mechanism 230 prevents the liquid matrix within the second reservoir 214 from exiting or flowing out. And, in FIGS. 5 and 7, a schematic of the liquid transfer mechanism 230 is shown in a second position in which the liquid transfer mechanism 230 allows the liquid matrix within the second liquid storage chamber 214 to exit or flow out.
Specifically, the fluid transfer mechanism 230 is at least partially disposed within the socket 220 when in the first position. When the liquid source 200 is coupled to the device main body 100, the connector 151 is inserted into the plug 220 to actuate the liquid transfer mechanism 230, so that the liquid transfer mechanism 230 moves from the first position to the second position, as indicated by arrow P1 in fig. 7. The liquid transfer mechanism 230 is movable from a first position to a second position in the width direction of the liquid source 200.
And in use, the user can attach the liquid source 200 to the device body 100 by manipulating the liquid source 200 on the second side 140 and pressing the liquid source 200 against the first side 130 while aligning the socket 220 with the connector 151, as indicated by arrow P2 in fig. 6.
In some alternative embodiments, the device body 100 is further provided with a structure such as a rail or a chute exposed to the holding space 150, which may be, for example, horizontally arranged, and the liquid source 200 provides guidance in the rail or chute during movement of the liquid source 200 from the second side 140 of the device body 100 towards the first side 130 for coupling to the holding space 150. And when the liquid source 200 is combined with the device main body 100, at least part of the liquid source 200 is embedded or extends into the guide rail or the sliding groove to form a buckling connection, so that separation caused by falling and the like in use is prevented.
As shown in fig. 4 to 7, the liquid transfer mechanism 230 includes:
a substantially cylindrical sealing valve 231, the wall of the sealing valve 231 being provided with perforations 232;
a second capillary element 233 is located within the sealing valve 231.
The sealing valve 231 is movable from a first position to a second position and from a closed state to an open state, the sealing valve 231 in the closed state preventing the liquid matrix of the second liquid storage chamber 214 from flowing out and in the open state allowing the liquid matrix of the second liquid storage chamber 214 to flow out. Specifically, the sealing valve 231 breaks fluid communication between the second capillary element 233 and the second reservoir 214 in the closed state, and the sealing valve 231 conducts fluid communication between the second capillary element 233 and the second reservoir 214 in the open state.
In some embodiments, the second capillary element 233 comprises or is made of flexible fibers such as cotton fibers, nonwoven fabrics, or sponges, etc.
When the liquid transfer mechanism 230 is in the first position, the perforations 232 of the sealing valve 231 do not extend into the second liquid storage chamber 214, the second capillary element 233 is fluidly isolated from the second liquid storage chamber 214, and the sealing valve 231 is closed or seals the second liquid storage chamber 214. When the liquid transfer mechanism 230 moves to the second position, the sealing valve 231 at least partially protrudes into the second liquid storage cavity 214, and the perforation 232 of the sealing valve 231 is exposed to the second liquid storage cavity 214, so that the liquid substrate in the second liquid storage cavity 214 can flow to the second capillary element 233 through the perforation 232 to be sucked up, as shown by arrow R31 in fig. 5 and 7.
In use, when the liquid matrix of the second liquid storage chamber 214 flows to the device body 100 via the sealing valve 231, the second capillary element 233 can absorb and buffer the liquid matrix by capillary action to adjust the flow rate of the liquid matrix from the liquid source 200 to the first liquid storage chamber and/or the liquid holding element 23, thereby preventing the liquid matrix from flowing too fast to cause leakage and releasing the liquid matrix when the liquid matrix flows slowly to ensure the supply rate.
And according to fig. 7, when the liquid source 200 is coupled to the device body 100, the first capillary element 154 and the second capillary element 233 are in contact, thereby regulating the flow rate of the liquid matrix in the liquid transfer channel established by the joint 151 and the sealing valve 231.
In some embodiments, the volume of the first reservoir within the device body 100 is less than the volume of the second reservoir 214 of the liquid source 200. The first reservoir is capable of absorbing and storing an amount of liquid matrix that is less than the amount of liquid matrix absorbed and stored by the second reservoir 214 of the liquid source 200. For example, in some embodiments, the first reservoir within the device body 100 can aspirate and store 0.5-3 mL of the liquid matrix, more particularly, for example, 2mL, and the second reservoir 214 of the liquid source 200 can store 5-20 mL of the liquid matrix, more particularly, for example, 10mL.

In some embodiments, the airflow channel of the device body 100a is collectively defined by a plurality of components for defining an airflow path for air through the device body 100a and delivering aerosol to the air outlet 111a. The fitting slit or hole or the like of the housing 10a of the apparatus main body 100a defines an air inlet for the entry of outside air in suction. According to the air flow path shown by arrow R2 in fig. 13, the air entering the apparatus main body 100a passes through the support member 52a and the second sealing member 51a in order into the middle hole of the liquid guiding member 30a, and carries the aerosol out from the second tubular member 22a and the aerosol output pipe 112a to the air outlet 111a. The absorbing element 25a serves to absorb aerosol condensate of air delivered to the air outlet 111a or to absorb aerosol condensate falling from the inner surface of the aerosol delivery tube 112 a.
As shown in fig. 10 to 13, the apparatus main body 100a further includes:
a connector 151a at least partially exposed within the holding space 150a for coupling or inserting the liquid source 200a into the liquid source 200a to replenish the liquid matrix to the device body 100 a;
the elbow 155a defines a fluid replenishment channel therein, communicating the junction 151a with the first reservoir for providing a channel path for fluid substrate to flow from the junction 151a to the first reservoir. The bent pipe 155a is connected and fixed with the first tubular element 21a through a connecting part extending from the first tubular element 21a, and is communicated with the first liquid storage cavity.
In this embodiment, the bent tube 155a is at least partially bent and is located between the cell 160a and the holding space 150a, and the joint 151a is arranged extending in the longitudinal direction and is connected to an end of the bent tube 155a facing away from the first liquid storage chamber. The joint 151a protrudes from the inside of the housing 10a of the apparatus main body 100a in the longitudinal direction to the holding space 150a and is exposed to the holding space 150a.
A first capillary element 154a is disposed within the fitting 151a and/or the elbow 155a for regulating the transfer rate of the liquid matrix within the liquid replenishment channel. The first capillary element 154a extends from the junction 151a through the elbow 155a to the first reservoir or liquid retaining element 23 a.
In some embodiments, the first capillary element 154a may be formed from a single piece of capillary material that is bent sequentially through the joint 151a and the elbow 155 a. Or in still other embodiments the first capillary element 154a may be formed or defined by two pieces of capillary material together, e.g., one capillary material passing through a portion of the elbow 155a in the width direction, another capillary material passing through the joint 151a and a further portion of the elbow 155a in the longitudinal direction, and the two capillary materials abutting contact at the bend of the elbow 155a to form the first capillary element 154a.
In this embodiment, as shown in fig. 10 to 13, the liquid source 200a includes:
An outer body 210a comprising a housing or outer surface defining a liquid source 200a, the outer body 210a being defined by a first housing portion 211a and a second housing portion 212 a;
a flexible sealing element 213a at least partially positioned between the first housing portion 211a and the second housing portion 212a to provide a seal therebetween;
A second reservoir 214a for storing a liquid matrix.
In this embodiment, the second housing portion 212a defines a liquid outlet 2141a for delivering liquid matrix from the second liquid storage chamber 214a, and a flexible sealing valve 231a is disposed within the second housing portion 212a, the sealing valve 231a comprising:
When the liquid source 200a is coupled to the apparatus body 100a, the connector 151a of the apparatus body 100a can be inserted into the connector 232a;
And a sealing portion 233a for blocking and sealing the liquid outlet 2141a, and when the liquid source 200a is coupled to the apparatus main body 100a, the sealing portion 233a can be pierced by the joint 151 of the apparatus main body 100a inserted from the plug-in port 232a, thereby opening the liquid outlet 2141a. For example, fig. 12 shows a schematic view of the sealing portion 233a shielding and sealing the liquid outlet 2141a before piercing, and fig. 13 shows a schematic view of the sealing portion 233a after piercing by the joint 151a of the device main body 100 a.
According to fig. 12 and 13, in this embodiment, at least part of the first capillary element 154a extends out of the device body 100a via the connector 151a, and further, after the connector 151a pierces or passes through the sealing portion 233a, the first capillary element 154a extends into the second liquid storage chamber 214a of the liquid source 200 a. The length of the first capillary element 154a exposed outside the device body 100a is about 3-6 mm.
In this embodiment, when the liquid source 200a is coupled to the device body 100a, the liquid transfer channel between the first liquid storage chamber and the second liquid storage chamber 214a is established with the elbow 155a after the joint 151a pierces or passes through the sealing portion 233a to replenish the liquid substrate in the second liquid storage chamber 214a to the first liquid storage chamber. The first capillary element 154a absorbs and buffers the liquid matrix in the liquid transfer channel by capillary action to adjust the flow rate of the liquid matrix from the liquid source 200a to the first reservoir and/or the liquid retaining element 23a, thereby preventing liquid leakage caused by too fast liquid matrix flow and releasing the liquid matrix when the liquid matrix flows slowly to ensure the supply rate.
According to fig. 10 to 13, when the liquid source 200a is coupled to the device body 100a, after the joint 151a pierces or passes through the sealing portion 233a, a portion of the sealing valve 231a is positioned between the joint 151a and the outer body 210a and provides a seal, so as to prevent a gap from being generated between the joint 151a and the outer body 210a to form a liquid leakage.
As shown in fig. 10 to 13, in this embodiment, a card hole 180a is further disposed on the housing 10a of the apparatus body 100a, and a card protrusion 215a is further disposed on the outer body 210a of the liquid source 200 a. In one aspect, the snap apertures 180a and snap tabs 215a are aligned for providing a positioning or alignment guide when the liquid source 200a is coupled to the device body 100 a. In yet another aspect, when the liquid source 200a is coupled to the device body 100a, the snap tabs 215a can extend into the snap apertures 180a to form a connection with the housing 10a of the device body 100a, thereby allowing the liquid source 200a to remain stably coupled to the device body 100a to prevent their release or separation.
