Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, in particular to an air valve-pushing liquid discharging device with a residual quantity indicator. Background Art

[0002] Cosmetics are classified by dosage form: liquid: facial cleanser, bath gel, shampoo, lotion, perfume, cleansing water, makeup remover, essence, stock solution, etc.; emulsion: honey, milk, hair conditioner, essence; cream: face cream, foundation cream, shampoo, concealer, hair treatment, essence, primer; powder: scented powder, talcum powder, loose powder, cleansing powder, honey powder; block: pressed powder, blush powder, lipstick, hair wax; oil: makeup remover, moisturizing oil, hair oil, essence oil. Existing cosmetics are generally stored in squeeze or press bottles. When using cosmetics, the shape of the bottle can be changed by manually pressing or squeezing the bottle, so that the cosmetics in the bottle can be easily squeezed out. For example, our company has proposed an air-push vacuum replaceable packaging bottle according to the publication number CN217576355U, which has a large liquid output, is easy to use, and is suitable for medium and high viscosity materials. Through the vacuum piston structure, the material residue is small and the air is isolated, and the shelf life is extended. At the same time, the packaging bottle has a simple structure and does not require a conventional pressing pump head, saving packaging material costs. The liner can be replaced, so that the remaining parts of the packaging bottle can be reused, energy-saving and environmentally friendly. The liquid outlet is at the bottom, which is convenient and clean to use, thus avoiding the problem that the conventional pressing pump head is at the top and the material at the liquid outlet will remain on the bottle. However, when in use, the bottle will have the problem that the soft rubber surface is easy to absorb dust, and the soft rubber is easy to fade over time. When in use, it is necessary to use a finger to block the small hole and press the soft rubber. However, some customers may not read the instructions in detail, resulting in not using a finger to block the small hole to press the soft rubber, which makes it impossible to push the material out. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a gas valve-pushed liquid outlet device with a residual amount indicator, which solves the problems raised in the above-mentioned background technology.

[0012] 1. The air valve-pushing liquid discharge device with a residual indication can discharge all the material in the first inner tank by adopting an air valve structure composed of a first spring, a second piston and a first piston, so as to achieve zero material residue, thereby avoiding the problem that when the existing product is used, some customers are not familiar with the operation method, resulting in the first air hole not being blocked, thus making it impossible to push the material, and avoiding the problem that the soft rubber surface of the existing product is prone to adsorb dust when used, and the soft rubber is prone to fading over time. When the first one-way valve fails, the first air hole can be blocked for pushing the material, and by setting the first one-way valve and the second air hole, one-way sealing and air intake can be achieved, thereby achieving rapid liquid discharge.

[0013] 2. The air valve-pushed liquid discharge device with a residual indication is provided with a perspective window and a scale display panel. When a user looks at the side of the first bottle body, through the perspective window, he can see that part of it is yellow and part of it is red, indicating that the material is about to be used up and a new first liner needs to be prepared for use. When looking at it from the side, no yellow and red are seen, indicating that the first liner is still within the normal use range. When looking at it from the side, it is all red, indicating that the material has been used up and the first liner needs to be replaced. By checking the extension of the convex column, the use of the material can be understood. The use of the material can be displayed through the two residual display structures.
