Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the embodiment of the present invention and accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.It should be noted that, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment
Refer to Fig. 1, the invention discloses a kind of syringe type toothpaste, comprise housing 1, main piston 2, air bag 3 and air pump 4; Cylindrically, the bottom of housing 1 is provided with one and exports mouth 5 housing 1, exports mouth 5 and is provided with capping; Main piston 2 is located at the inside of housing 1 and is fitted with the inner wall sealing of housing 1, and toothpaste is loaded in the space between the output mouth 5 of main piston 2 and housing 1; The top of housing 1 is located at by air pump 4, and air bag 3 is located between main piston 2 and air pump 4, and air bag 3 is connected with the air extractor duct of air pump 4.
In the process used, by inflating air bag 3, air bag 3 starts to expand, and then promotion main piston 2 moves downward, because the inner wall sealing of main piston 2 and housing 1 is fitted, so main piston 2 fully can extrude the toothpaste inside housing 1 in motion process, residual waste can not be produced.Meanwhile, air bag 3 by gas and toothpaste completely isolated, ensure that the health of toothpaste.Squeezing toothpaste is changed into unified operation air pump 4 to the extruding of hose packing completed extruding by traditional, operates compared with the convenient health of traditional product.
As preferably, described air pump 4 comprises the pump housing 6, spring, the first check valve 9, second check valve 10, auxiliary piston 7 and button 8; Be provided with main gas circuit 11 through vertically in the pump housing 6 and radially through enter gas gas circuit 12, main gas circuit 11 one end be positioned at bottom the pump housing 6 is the air extractor duct of the pump housing 6, and air extractor duct is provided with the first check valve 9 of one-way exhaust; Enter gas gas circuit 12 and be connected conducting with the middle part of main gas circuit 11, enter the air intake that one end that gas gas circuit 12 is positioned at the pump housing 6 side is the pump housing 6, air intake be provided with unidirectional enter the second check valve 10 of gas; Auxiliary piston 7 is located at main gas circuit 11 inside and is fitted with the inner wall sealing of main gas circuit 11; Button 8 is located at the top of the pump housing 6 and is rigidly connected with auxiliary piston 7; Spring is located between button 8 and the pump housing 6.
