Problems solved by technology

However, there is a big defect in adopting the above-mentioned structures, that is, when the bottle body is once squeezed and the bottle body is loosened, part of the liquid will flow out from the liquid outlet of the bottle cap. In a negative pressure state, part of the liquid in the pump body will flow back into the bottle from the liquid inlet of the pump body, resulting in a large deviation in the quantitative distribution of the liquid dose, and the real quantitative distribution cannot be realized

Embodiment 2

[0046] Such as Figure 13 As shown, the difference between this embodiment and Embodiment 1 is that the piston 3 in this embodiment includes a floating member 34 and a floating ball 35, and the floating member 34 moves upward by the piston 3 to seal the first liquid outlet 11 of the bottle cap 1. , the piston 3 moves downwards and the floating ball 35 seals the second liquid inlet 22 at the bottom of the pump body 2 . Specifically, the upper part of the floating member 34 has first floating sheets 341 arranged at intervals along the circumferential direction, and the lower part of the floating member 34 has a plurality of elastic claws 342 arranged at intervals along the circumferential direction. In the cavity formed by the foot 342 enclosure. The floating part 34 is provided with a through hole 343 for the liquid to flow through, and the lower end surface of the floating part 34 is formed with an assembly ring 344 arranged around the outer periphery of the through hole 343....

Embodiment 3

[0049] Such as Figure 14 As shown, the difference between this embodiment and Embodiment 2 lies in that the floating member 34' and the floating ball 35' in this embodiment are provided separately, and correspondingly, the internal structure of the pump body 2 is also different. A platform 25 capable of flowing through the liquid is formed on the inner wall of the pump body 2, and a floating member 34' that can move up and down is located above the platform 25. The platform 25 is provided with a plurality of first through holes 251 arranged at intervals along the circumferential direction near the edge, and the middle part of the platform 25 has an extension part 252 extending toward the first liquid outlet 11, and the extension part 252 is provided with a second through hole. 253, and the inner peripheral wall of the second through hole 253 is formed into an arc-shaped surface that can fit the outer peripheral surface of the floating ball 35', and the lower end surface of th...

Embodiment 4

[0052] Such as Figure 15 As shown, the difference between this embodiment and Embodiment 1 is that the piston structure of this embodiment also includes a floating ball 35', while the structure of the piston 3 body is the same as that of Embodiment 1, and at the same time, in order to cooperate with the floating ball 35', In this embodiment, the same platform 25 structure as that in Embodiment 3 is also provided.

[0053] Adopting the piston structure of this embodiment, its use process is the same as that of Embodiment 3.

[0054] It should be noted that the structure of the piston in the present invention can be various, as long as it can cooperate with the pump body to achieve the effect of quantitatively extruding the liquid in the pump body.

Abstract

The invention relates to a quantitative device for distributing liquid doses. An elastic valve is provided on the basis of the prior art. The mouth is sealed to prevent the liquid from flowing out before the quantitative volume accumulation is completed. During the extrusion process, the elastic sheet is shifted to the inner side of the pump body so that the liquid flows into the pump body from the first liquid inlet; after the extrusion is completed, loosen the bottle body , a negative pressure is formed in the bottle, the elastic sheet is tightly attached to the first liquid inlet to prevent the liquid in the pump body from flowing out, and the sealing sheet blocks the liquid in the pump body to prevent it from flowing out from the first liquid outlet of the bottle cap. And the gas can enter the bottle from the second liquid outlet to prepare for the next quantitative liquid discharge; the arrangement of the elastic valve enables the present invention to realize the quantitative distribution of liquid doses in the true sense, and increases the liquid viscosity of the quantitative device Scope of application, the application range of liquid viscosity can reach 1 ~ 2000mPa·s.

Description

technical field [0001] The invention relates to a dosing device for dispensing liquid doses. Background technique [0002] At present, most of the liquids that are easy to carry are contained in plastic bottles. When using them, you need to open the cap and tilt the bottle body to pour out the liquid in the bottle. However, such a structure makes it difficult to quantify the amount of liquid poured out each time. control. [0003] In order to solve the above problems, the applicant has applied for liquid quantitative extrusion devices using different extrusion principles and schemes in 2014 and 2015, including the Chinese invention patent application "Used for Liquid Quantitative Extrusion" with the application publication number CN103818630A Bottle cap" (application number: 201410086594.2), Chinese invention patent application "a liquid quantitative extrusion device" (application number: 201510253847.5), application publication number CN104943972A Chinese invention patent ...
