[0026] Reference Figure 1-3 The figure shows a preferred embodiment of the present invention.

[0027] The self-priming cream pump with propulsion includes a bottle body 100. The lower part of the bottle body 100 is provided with a piston 600 which moves upward in one direction under pressure and is connected to the atmospheric pressure. When the piston 600 is under pressure, it can only move upward in one direction, and the atmospheric pressure is used to push the piston 600 to move upward in one direction.

[0028] The paste here refers to a substance with a certain consistency, such as toothpaste, cosmetics, skin care products, shampoo, etc., and is not limited to a specific substance.

[0029] The bottle body 100 has a rubber bowl 300 in the upper part, which is elastically deformed and pops up to reset upward, that is, when the rubber bowl 300 is pressed, it is compressed and deformed downward, and when the rubber bowl 300 is released from the pressure, the rubber bowl 300 pops up to reset upward. The inside of the rubber bowl 300 is surrounded by a bowl cavity 301 containing the lotion, which penetrates the top of the rubber bowl 300 to form a top opening, and penetrates the bottom of the rubber bowl 300 to form a bottom opening.

[0030] The piston 600 and the rubber bowl 300 have a lotion cavity 101 containing the lotion, and the top of the bottle body 100 is provided with a pressing head 200 that drives the rubber bowl 300 to compress and deform by pressing. The pressing head 200 has a liquid outlet 201 formed therein, which has a liquid outlet 202 and a liquid inlet, and the liquid inlet communicates with the top opening of the rubber bowl 300. In this way, the lotion in the bowl cavity 301 can enter the liquid outlet 201 through the top opening, enter the liquid outlet 201 through the liquid inlet, and be discharged through the liquid outlet 202.

[0031] When the pressing head 200 drives the rubber bowl 300 to compress and deform downward, the rubber bowl 300 is compressed, the bowl cavity 301 is reduced, the lotion in the bowl cavity 301 enters the liquid outlet 201, and the lotion in the bowl cavity 301 is squeezed out of the liquid outlet 201; when the rubber bowl 300 is elastically reset upward after the pressing head 200 is released from the pressure, the rubber bowl 300 sucks the lotion upward, and the piston 600 pushes the lotion upward, so that the lotion in the lotion cavity 101 is pushed into the bowl cavity 301 by the combination of suction and pushing, so that the bowl cavity 301 is filled with the lotion.

[0032] The above-mentioned self-suction type lotion pump with pushing function, when the pressing head 200 presses the rubber bowl 300 to compress and deform, the lotion in the bowl cavity 301 is squeezed out of the liquid outlet 201, and when the rubber bowl 300 is elastically reset upward after the pressing head 200 is released from the pressure, the rubber bowl 300 sucks the lotion upward, and the piston 600 pushes the lotion upward, so that the rubber bowl 300 is elastically reset and the piston 600 is pushed upward to form a linkage effect, so that the lotion cavity 101 is filled with the lotion, realizing efficient discharge of the lotion, and the operation is convenient and the experience is strong.

[0033] In this embodiment, the top of the rubber bowl 300 and the pressing head 200 are relatively fixed by inserting and connecting as a whole, so that the elastic movement of the rubber bowl 300 is consistent with the movement of the pressing head 200. When the pressing head 200 is pressed downward, the rubber bowl 300 is compressed and deformed synchronously, and when the pressing head 200 is released from the pressure, the rubber bowl 300 is elastically reset upward, driving the pressing head 200 to move upward.

[0034] In this embodiment, a connecting post 303 protrudes upward from the top of the gel bowl 300. The top opening is formed in the connecting post 303. The connecting post 303 is inserted into the liquid outlet 201 and integrally connected to the pressing head 200. The insertion of the connecting post 303 into the liquid outlet 201 can further strengthen the connection between the pressing head 200 and the gel bowl 300.

[0035] In this embodiment, the gelatin bowl 300 is conical, with its diameter gradually increasing from top to bottom. The bottom opening of the gelatin bowl 300 is open. Thus, when the gelatin bowl 300 is compressed and deformed, the cream in the bowl cavity 301 is squeezed into the liquid outlet 201. When the gelatin bowl 300 elastically returns upward, the gelatin bowl 300 is quickly and accurately reset. Furthermore, the open bottom opening allows the gelatin bowl 300 to self-prime the cream in the cream cavity 101 when it elastically returns upward, facilitating the cream in the cream cavity 101 to enter the bowl cavity 301.

[0036] In this embodiment, the bottom of the colloid bowl 300 is fixedly arranged, and the middle part of the colloid bowl 300 is movably arranged. In this way, when the colloid bowl 300 is compressed and deformed, the bottom is kept fixed, and the colloid bowl 300 is compressed and deformed from the top downward, so that the paste in the bowl cavity 301 can enter the liquid outlet 201. When the colloid bowl 300 elastically resets upward, it can be quickly reset. During the reset process, a vacuum area is formed in the upper part of the bowl cavity 301, and the self-priming effect of the paste is realized upward. Under the action of the external atmospheric pressure, the piston 600 is pushed upward in one direction.

[0037] In this embodiment, a fixed annular wall 302 is formed on the outer periphery of the colloid bowl 300. The fixed annular wall 302 is arranged around the circumference of the colloid bowl 300 and is fixedly connected to the bottle body 100, thereby fixing the bottom of the colloid bowl 300 relative to the bottle body 100. The arrangement of the fixed annular wall 302 facilitates the fixed connection between the bottom of the colloid bowl 300 and the bottle body 100.

[0038] When the pressing head 200 is released, the upper one-way valve 304 is closed during the upward elastic reset of the gel bowl 300. At this time, the bowl cavity 301 and the liquid outlet 201 are separated. Due to the vacuum area in the bowl cavity 301, the piston 600 is pushed upward, and the gel bowl 300 self-primes the gel, so that the gel in the gel cavity 301 will quickly enter the bowl cavity 301 and the gel bowl 300 will quickly and elastically reset. In this process, the gel in the bowl cavity 301 will not continue to enter the liquid outlet 201.

[0039] In this embodiment, a partition layer 400 is provided below the colloid bowl 300, which separates the bottom opening from the paste liquid chamber 101; a lower one-way valve 401 that opens in one direction upward is provided in the partition layer 400. When the colloid bowl 300 elastically resets upward, the lower one-way valve 401 opens, and the paste liquid chamber 101 is connected to the bottom opening.

[0040] In this way, when the pressing head 200 presses the gel bowl 300 downward to compress and deform it, the lower one-way valve 401 is closed at this time, and the bowl cavity 301 is separated from the cream liquid cavity 101. When the cream liquid in the bowl cavity 301 is squeezed, the cream liquid in the bowl cavity 301 is prevented from moving downward. In this way, the liquid outlet 201 can quickly discharge the liquid and maintain stable liquid discharge. When the gel bowl 300 elastically resets upward, the lower one-way valve 401 opens, and the cream liquid in the cream liquid cavity 101 can enter the bowl cavity 301.

[0041] Of course, for some pastes with higher viscosity, there is no need to set the lower one-way valve 401, while for some pastes with lower viscosity, it is necessary to set the lower one-way valve 401. The viscosity here refers to the fluidity of the paste, and the specific value of the viscosity can be determined according to actual experiments.

[0042] In this embodiment, a support platform 500 is provided below the colloid bowl 300. The support platform 500 is fixed relative to the bottle body 100 and has a through hole 501 extending vertically therethrough. The lower one-way valve 401 is disposed on the support platform 500, aligned vertically with the through hole 501. The support platform 500 ensures a secure installation of the barrier layer 400, maintaining its position.

[0043] In this embodiment, the lower one-way valve 401 is arranged in the middle of the isolation layer 400, and an annular wall 403 is formed on the outer periphery of the lower one-way valve 401. A plurality of reinforcing ribs 402 are provided between the annular wall 403 and the outer periphery of the isolation layer 400. The plurality of reinforcing ribs 402 are arranged around the circumference of the annular wall 403, and the reinforcing ribs 402 are arranged in a curved shape.

[0044] By arranging the reinforcing ribs 402 , the structure of the isolation layer 400 is kept stable, and the lower one-way valve 401 will not be deformed during the process of opening or closing, thereby keeping the lower one-way valve 401 accurately opened or closed.

[0045] In this embodiment, a bottom shell 800 is provided at the bottom of the bottle body 100, and the bottom shell 800 is located below the piston 600. The bottom shell 800 is provided with a bottom hole 801 arranged vertically through the bottom shell 800. The external atmospheric pressure is connected to the piston 600 through the bottom hole 801. In this way, when the colloid bowl 300 elastically resets upward, a vacuum area appears in the bowl cavity 301, which is in a negative pressure state. The external atmospheric pressure drives the piston 600 upward through the bottom hole 801.

[0046] In addition, in order to limit the downward movement of the piston 600, a check member 700 is connected to the piston 600. The check member 700 limits the downward movement of the piston 600 and limits the piston 600 to only moving upward. In this way, when the pressing head 200 presses downward, if the lower one-way valve 401 is not set, the check member 700 can limit the downward movement of the piston 600 to avoid affecting the discharge of the paste.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
