[0049] Compared with the prior art, the beneficial effects of this utility model are:

[0050] 1. Because the press pump in this utility model is installed in a first predetermined container fitted with a second predetermined container, the first predetermined container has a first container opening and a first container part, the direction from the first container opening to the first container part is taken as the depth direction, and the first predetermined container and the second predetermined container are parallel in the depth direction, the press pump includes a press head and a pump body, the press head is movably fitted onto the pump body along the depth direction, and the interior of the press head and the interior of the pump body form an installation chamber, including an elastic body, which is installed in the installation chamber along the depth direction, its upper surface is interference-fitted with the press head, and the elastic body has an elastic body chamber. Extending along the depth direction, the purpose is to achieve a good seal between the elastomer and the pressing head.

The elastomer base has sealing skirts along the depth direction. The sealing skirt is interference-fitted with the pump body to form a sealed chamber, aiming to achieve a good seal in the sealed chamber. The pump body is equipped with a first one-way valve, which has a first one-way valve skirt. The first one-way valve skirt is continuously closed and located on the upper surface of the pump body in the depth direction, used to seal the sealed chamber and the first container opening. The first liquid chamber is connected to the mounting chamber, the sealed chamber, and the first container opening to form a first liquid flow channel through the first container, the first container opening, the interior of the pump body, the sealed chamber, the first liquid chamber, and the press head.

The first end extends into the mounting chamber, and the other end extends sequentially from the first liquid chamber and the mounting chamber along the depth direction to connect with the inside of the second predetermined container, thereby forming a second liquid channel between the inside of the second predetermined container, the inside of the pump core, and the pressing head. The purpose is to compress and reset the elastic body by pressing a pressing head, so that the elastic body has an energy storage function and can be used as a piston. For this purpose, the energy storage and release process of the elastic body is used to realize the simultaneous pumping of two liquids from the first predetermined container through the first liquid channel and the second predetermined container through the second liquid channel. Therefore, compared with the prior art, the structure is simple and easy to process.

[0051] 2. In this utility model, the area enclosed by the lower surface of the pump core piston along the depth direction, the pump liquid chamber, and the third one-way valve skirt is designated as the first area, and the volume within the first area is designated as the first volume. The area enclosed by the first liquid chamber, the sealed chamber, and the upper surface of the first one-way valve along the depth direction is designated as the second area, and the volume within the second area is designated as the second volume. When the pressing head is in the pressing stroke, the ratio of the change value of the first volume to the change value of the second volume is a constant. Therefore, this pressing pump can not only achieve the situation where pressing the pressing head once can pump out two liquids simultaneously, but also, based on this constant value, can achieve the situation where two liquids can be pumped out simultaneously in proportion. Therefore, it has greater practical significance.

[0052] 3. Because a self-locking structure is provided between the pressing head and the pump body in this utility model, the purpose is to achieve self-locking after the pressing head moves on the pump body, which can effectively prevent the liquid in the first and second predetermined containers from being squeezed out due to collision or accidental contact with the pump head.

The outer edge of the first mounting part 41 of the pump body is the outer skirt 4112 of the first mounting part of the pump body, and the outer skirt 4112 of the first mounting part of the pump body extends in the opposite direction of the depth direction A.

[0079] Furthermore, as shown in 7-11, in this embodiment, the pump core 7 is configured as a split structure, that is, the pump core 7 is configured as a first connecting part and a second connecting part, which are matched along the depth direction, and the pump core chamber is formed by the inner cavity of the first connecting part and the inner cavity of the second connecting part. The second discharge valve 714, the pump core sealing valve 715, and the first discharge valve 713 are all located on the first connecting part of the pump core, and the pump core piston and the pump core sealing skirt are located on the second connecting part of the pump core. The first connecting part of the pump core is provided with equal spacing. Multiple connecting protrusions 716 are provided, and the elastic body 5 is in contact with the multiple connecting protrusions 716; and a first connecting part gap of the pump core is provided between each two adjacent connecting protrusions 716. The first liquid flows through the first container part 12, the first container opening part 11, the inside of the pump body 4, the sealed chamber 621, the first liquid chamber, and the first liquid flow hole 3115 on the pressing head 3, and enters the pressing chamber 311 from the first liquid chamber through the first connecting part gap of the pump core, and then is ejected through the first liquid flow hole 3115.

[0080] In another embodiment, the pump core 7 can be configured as an integral structure.

[0081] The area enclosed by the lower surface of the pump core piston 712 along the depth direction A, the pump liquid chamber 431, and the third one-way valve skirt is designated as the first area, and the volume within the first area is designated as the first volume. The area enclosed by the first liquid chamber, the sealed chamber 621, and the upper surface of the first one-way valve 44 along the depth direction is designated as the second area, and the volume within the second area is designated as the second volume. When the pressing head 3 is in the pressing stroke, the ratio of the change value of the first volume to the change value of the second volume is a constant value. The purpose is to achieve the simultaneous proportional pumping of two liquids with one press using this press pump.

[0082] In addition, such as Figure 2 , 5 As shown in Figures 7, 8, and 12, a self-locking structure is provided between the pressing head 3 and the pump body 4 to enable the pressing head 4 to self-lock after moving on the pump body 1.

[0083] Specifically: the outer skirt 4112 of the first mounting part of the pump body has a pressing notch 41121, and the pressing notch 41121 is open in the opposite direction of the depth direction A. The pressing head 3 moves along the pressing notch 41121 on the pump body 4 in the depth direction A or its opposite direction to realize the pressing action of the pressing head 3. The outer skirt 4112 of the first mounting part of the pump body is provided with a stop part 41122. The stop part 41122 is continuous with the final position of the pressing notch 41121 in the opposite direction of the depth direction A. The pressing inner cavity 311 is provided with a snap-fit ​​part 3113 that matches the stop part 41122. When the snap-fit ​​part 3113 moves to the stop part 41122 in the pressing notch 41121, the pressing head 3 realizes the pressing action until the pressing stops or stops the pressing until the pressing action starts, that is, it realizes self-locking or releases self-locking.

[0084] More specifically: A waist-shaped hole 41123 is provided on the side wall of the pressing head 3 (depending on the actual situation, the number of waist-shaped holes 41123, pressing notches 41121, limiting blocks, and stop portions 41122 are equal and there are several of each). The waist-shaped hole 41123 is arranged circumferentially around the pressing head 3. A limiting block matching the waist-shaped hole 41123 is provided on the outer skirt 4112 of the first mounting part of the pump body. An inclined surface is provided on the outer skirt 4112 of the first mounting part of the pump body where the pressing notch 41121 is located. When the pressing head 3 is inside the pressing notch 41121... The rotating motion allows the limiting block to slide within the waist-shaped hole 41123. This enables the locking member 3113 to rotate within the pressing notch 41121 (which is formed by a notch between an arc-shaped protrusion and a flange in the opposite direction of the depth direction A of the outer skirt 4112 of the first mounting part of the pump body) to the stop part 41122. At this time, the pressing head 3 performs a rotating pressing motion until it stops pressing or stops pressing until the rotating pressing motion begins, thus achieving rotating self-locking or rotating release self-locking.

[0085] This utility model is mainly implemented in the following manner;

[0086] When the press head 3 is pressed for the first time along the depth direction A, the press head 3 moves along the depth direction A, thereby driving the elastic body 4 to compress along the depth direction. At this time, the pressure of the elastic body 4 increases, and the elastic body 4 is in an energy storage state. At the same time, during the energy storage process of the elastic body 4, the pump core 7 also moves along the depth direction A, that is, the pump core piston 712 moves in the pump liquid chamber 431 until the end face of the pump core piston 712 contacts the bottom of the pump liquid chamber 431. Then the press head 3 is released, and the energy stored in the elastic body 4 is released, driving the pump core piston 712 to move in the opposite direction of the depth direction A, so that the first liquid chamber The pressure inside decreases until a vacuum is formed in the first liquid chamber, that is, the pump piston 712 moves away from the bottom of the pump chamber 431. Since the internal pressure of the first predetermined container 1 and the second predetermined container 2 is constant and greater than that of the first liquid chamber, the first one-way valve skirt on the first one-way valve 44 is pushed in the opposite direction of the depth direction A of the first predetermined container 1. Therefore, when the pressure inside the first predetermined container 1 is greater than the pressure of the first liquid chamber, the first one-way valve skirt opens, so that even if the first predetermined container 1 is connected to the first liquid flow channel, the liquid in the first predetermined container 1 passes through the first liquid flow channel. A suction tube 8 and the first liquid flow channel reach the first liquid outlet 3115 and are ejected. Simultaneously, during the energy release process of the elastic body 4, the pump core piston 712 is driven to move in the opposite direction of the depth direction A, reducing the pressure in the first region until a vacuum is formed in the first region, i.e., the pump core piston 712 moves away from the bottom of the pump chamber 431. Since the internal pressure of the first predetermined container 1 and the second predetermined container 2 is constant and greater than that of the first region, the third one-way valve skirt on the third one-way valve 46 is pushed by the second predetermined container 2 in the opposite direction of the depth direction A, thereby causing the second predetermined container 46 to... When the pressure inside container 2 is greater than the pressure in the first region, the third one-way valve skirt opens, connecting the second predetermined container 2 to the first liquid flow channel. The liquid in the second predetermined container 2 passes through the second suction tube 9 and the second liquid flow channel to the second flow hole 3116 and is ejected, thereby achieving the purpose of pumping out two liquids simultaneously with a single press of the pump. In addition, since the ratio of the first volume change value to the second volume change value is a constant during a single press of the press head 3, this utility model can achieve the purpose of pumping out two liquids simultaneously with a single press at a predetermined ratio.

[0087] In addition, during the pressing of the pressing head 3, the gas outside the pump enters the inner cavity 411 of the first mounting part of the pump body through the first gas flow channel, which increases the pressure inside the inner cavity 411 of the first mounting part of the pump body. Since the second one-way valve skirt of the second one-way valve 45 is located on the lower surface of the pump body 4 along the depth direction A, the second one-way valve 45 opens, thereby connecting the first fluid flow channel with the first predetermined container 1, so that the gas outside the pressing head 3 enters the first predetermined container 1 through the first gas flow channel to replenish the first predetermined container 1 with gas.

[0088] In addition, when the pump core 7 moves along the depth direction A, the pump core sealing skirt 717 also moves along the depth direction in the pump liquid chamber 431. When the pump core sealing skirt 717 moves to the point where the air inlet 432 is above the pump core sealing skirt 717, the second air inlet channel is connected, so that the gas outside the pressing head 3 enters the second predetermined container 2 through the second gas channel to achieve air replenishment to the second predetermined container 2.

[0089] It should also be noted that the liquid in the first predetermined container 2 has a higher concentration than the liquid in the second predetermined container 2 in this invention.

[0090] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications or variations that can be made by those skilled in the art without creative effort within the scope of the appended claims are still within the scope of protection of this patent.
