[0027] It should be noted here that: during the use of the pressing liquid extraction pump, the spring and piston of the traditional liquid extraction pump are cancelled, the structure of the traditional liquid extraction pump is simplified, the service life of the pump body is increased, and a soft rubber cavity is used to replace the piston, making it easy and effortless for consumers to press.

[0028] The pressure supply assembly includes a soft rubber fixed pressure ring 501 fixedly communicated with the outside of the pump body seat 204, and a soft rubber pressing cavity 502 is fixed on the soft rubber fixed pressure ring 501;

[0029] It should be noted here that: when pressing the soft rubber pressing cavity 502, under the action of the internal pressure of the pump body seat 204, the soft rubber one-way valve 203 is squeezed by the liquid and deformed and moved upward.

[0030] A plurality of groups of connecting members are arranged in an annular array state at the front end of the pump inlet head 201. The connecting members are card plates 3 arranged in an arrow shape, and the card plates 3 are fixed at the front end of the pump inlet head 201;

[0031] It should be noted here that: the pump inlet head 201 is installed on the material guiding port 104 at the lower end of the container 103 by being clamped by a plurality of groups of card plates 3.

[0032] There are two sets of sealing components on the liquid inlet head 201 of the pump for sealing with the inner side of the material guiding port 104 and the inner side of the pump body seat 204 during installation; the sealing component includes an annular groove 401 opened on the outer side of the liquid inlet head 201 of the pump, and an annular sealing ring 402 is installed inside the annular groove 401;

[0033] It should be noted here that during the installation of the liquid inlet head 201 of the pump with the material guiding port 104 and the pump body seat 204, the annular sealing rings 402 on the two sets of sealing components are respectively abutted against the inner walls of the material guiding port 104 and the pump body seat 204 to achieve the sealing effect.

[0034] The connecting component includes sliding grooves 601 opened on both sides of the housing 101, sliding pins 602 are slidably connected on the two sets of sliding grooves 601, the two sets of sliding pins 602 are respectively fixed to both sides inside the gland 102, and the upper end of the inner cavity of the gland 102 is abutted and connected to the upper end of the housing 101 by a clamping method;

[0035] It should be noted here that through the sliding grooves 601 and the sliding pins 602, it is convenient for the gland 102 to be slidably connected to the front side of the housing 101.

[0036] An extrusion pin 7 for abutting and extruding against the soft rubber pressing cavity 502 is fixed inside the gland 102;

[0037] It should be noted here that during the use of the pressing liquid extraction pump, through the extrusion of the gland 102, the gland 102 moves towards the inside of the housing 101. During the movement, the soft rubber pressing cavity 502 is abutted and extruded by the extrusion pin 7.

[0038] Working principle: During the use of the pressing liquid extraction pump, the soft rubber one-way valve 203 and the soft rubber one-way valve fixing part 202 are successively placed inside the pump body seat 204. After the placement is completed, the pump body seat 204 and the liquid inlet head 201 of the pump are threadedly connected. After the connection is completed, the liquid inlet head 201 of the pump is installed on the material guiding port 104 at the lower end of the container 103 by being clamped by multiple clamping plates 3. The assembly process of the entire pressing liquid extraction pump is simple and cost-saving;

[0039] And during the use of the pressing liquid extraction pump, through the extrusion of the gland 102, the gland 102 moves towards the inside of the housing 101. During the movement, the soft rubber pressing cavity 502 is abutted and extruded by the extrusion pin 7. When the soft rubber pressing cavity 502 is pressed, under the action of the pressure inside the pump body seat 204, the soft rubber one-way valve 203 is extruded by the liquid and deformed and moved upwards. During the movement of the soft rubber one-way valve 203, position A is abutted and extruded to achieve the sealing effect, so that the liquid will not flow back into the container 103, while position B is opened and the liquid flows out (see the above process forFigure 5 ) During the process of not squeezing the soft rubber pressing cavity 502, after the soft rubber pressing cavity 502 is squeezed, it will rebound. When it returns to its original state, suction is formed inside the cavity, causing the soft rubber one-way valve 203 to deform and move downward under the pull of the suction. During the movement, position A is opened, and the liquid inside the container 103 is sucked down and flows into the pump body seat 204, while position B is squeezed and sealed to prevent the liquid from flowing out of the pump body seat 204 (see the above process in Figure 6 ). Press and cycle like this to achieve the effect of pumping and discharging liquid.
