Detailed Embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0021] As Figures 1-4 shown, a vacuum dropper bottle includes a bottle body 1, a dropper 2 and a piston driver 4. The bottle body 1 is vertically through. The dropper 2 is connected and installed at the top opening of the bottle body 1. A through discharge channel 21 is provided on the dropper 2. In the present utility model, the dropper 2 is installed at the installation position of the original pressing pump head. The dropper 2 only has the function of discharging the cosmetic liquid. A piston 3 is movably installed in the bottle body 1. The internal space of the bottle body 1 above the piston 3 is set as a material cavity 11. The material cavity 11 is filled with cosmetic liquid. The discharge channel 21 communicates with the material cavity 11. The piston 3 can move vertically upward to push the cosmetic liquid in the material cavity 11 to flow and output in the direction of the discharge channel 21. The piston driver 4 is installed at the bottom opening of the bottle body 1. The piston driver 4 includes a liquid discharge button 41. The liquid discharge button 41 can form a shape change to push the piston 3 to move upward. The liquid discharge button 41 of the present utility model is made of soft rubber material and can be manually pressed and deformed. The liquid discharge button 41 adopts a U-shaped cross-section design. The liquid discharge button 41 is inserted into the bottom of the bottle body 1 with the open end. The piston 3 is provided with a first cavity 31, and the liquid discharge button 41 is provided with a second cavity 411. The first cavity 31 and the second cavity 411 are opposite and communicate. In this way, a space filled with air is formed between the piston 3 and the liquid discharge button 41. After pressing the liquid discharge button 41, the liquid discharge button 41 deforms, and the air space is compressed and becomes smaller, which can form a pressure to push the piston 3 upward. After the piston 3 moves upward, the liquid discharge effect at the position of the dropper 2 can be formed. In the present utility model, the piston driver 4 is used to replace the function of the pressing pump head. The piston driver 4 of the present utility model has a simple structure, low production cost, and is driven by the deformation of the body itself, and there is no mechanical failure problem. After the piston driver 4 is applied in the present utility model, the overall cost of the vacuum bottle product can be greatly reduced, so that the product has better market competitiveness, and the user experience is also guaranteed.

[0022] As Figure 2 and Figure 3 shown, an inner concave card seat 12 is formed in the top opening of the bottle body 1. The card seat 12 adopts an L-shaped cross-section design. The lower end of the dropper 2 is inserted and snap-connected in the card seat 12. Two convex rings 22 are formed on the outer wall of the lower end of the dropper 2. The dropper 2 is stably snap-connected to the card seat 12 through the convex rings 22. At the same time, the L-shaped cross-section and the two convex rings 22 can form a good sealing effect, so that the cosmetic liquid will not overflow from the connection between the bottle body 1 and the dropper 2.

[0023] As Figure 4 shown, a metal frame 413 is connected and installed on the inner wall of the open end of the liquid outlet button 41. The open end of the liquid outlet button 41 is the installation end of the liquid outlet button 41. The metal frame 413 makes the open end of the liquid outlet button 41 have a certain rigidity, which is convenient for installation. After the liquid outlet button 41 is installed, it is hermetically connected to the bottom of the bottle body 1. Two convex rings 22 protrude from the outer wall of the liquid outlet button 41. The liquid outlet button 41 is made of soft rubber. The two convex rings 22 can form two sealing effects at the installation gap position to ensure that there is no air leakage at the installation gap. The piston driver 4 further includes a fixed seat 42. The fixed seat 42 is fixedly connected to the bottom of the bottle body 1. The fixed seat 42 presses the liquid outlet button 41 upward. During assembly, the fixed seat 42 is installed after the liquid outlet button 41. The fixed seat 42 plays a role in supporting and fixing the liquid outlet button 41 and can prevent the liquid outlet button 41 from falling off abnormally.

[0024] As Figure 2 shown, a vacuum dropper bottle further includes a needle seal 5. The needle seal 5 is connected with a plug 51. The size of the plug 51 matches the size of the top of the discharge channel 21 of the dropper 2. The needle seal 5 is inserted into the discharge channel 21 with the plug 51 to complete the sealing of the dropper 2. Before use, the needle seal 5 needs to be removed. After use, the needle seal 5 should be installed in time so as to effectively isolate the pollution of the liquid in the bottle by external air.

[0025] As Figure 2 shown, a vacuum dropper bottle further includes a bottle cover 6. The bottle cover 6 is snap-connected to the bottle body 1. The bottle cover 6 plays a role in protecting the bottle mouth. After the bottle cover 6 is installed, the top of the inner cavity of the bottle cover 6 forms a downward pressing effect on the needle seal 5, which can ensure that the needle seal 5 is installed reliably and will not have the problem of accidental dropping.

[0026] As Figure 1 and Figure 4 shown, a ventilation hole 412 is opened at the top of the liquid outlet button 41. The ventilation hole 412 communicates with the second cavity 411. The design of the ventilation hole 412 enables external air to enter the air space formed between the piston 3 and the liquid outlet button 41. When the user uses the present utility model to discharge liquid, the ventilation hole 412 needs to be blocked with a finger first, and then the liquid outlet button 41 is squeezed. Only in this way can the pressure change in the air space be formed and the piston 3 be pushed upward. If the ventilation hole 412 is not blocked, even if the liquid outlet button 41 is pressed, the air will be discharged from the position of the ventilation hole 412, and the pressure change in the air space will not be caused, and the effect of pushing the piston 3 upward cannot be formed. Therefore, the design of the ventilation hole 412 can also prevent the liquid outlet button 41 of the present utility model from discharging liquid when being accidentally pressed (general accidental pressing will not cause the ventilation hole 412 to be blocked). The ventilation hole 412 is opened at the bottom of the liquid outlet button 41, which is convenient for the user to block the ventilation hole 412 with the thumb and is a design to improve the use experience.

[0027] As Figure 1 shown, a notch 421 is formed on the outer wall of the fixed seat 42. The notch 421 exposes a part of the side wall of the liquid discharging button 41. The bottom of the fixed seat 42 itself is open, and the liquid discharging button 41 can also be squeezed through the bottom of the fixed seat 42, but the operation is relatively inconvenient. After setting the side notch 421, it is more convenient for the user to operate the liquid discharging button 41 with one hand, which can greatly improve the using experience.

[0028] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications should also be regarded as the protection scope of the present invention.
