Description

Technical Field

[0002] A press pump is a device that extracts fluid from a container by pressing it, and it has wide applications in daily chemical, kitchen and bathroom, and medical fields. For example, in Chinese invention patent application publication number CN116588500A, the inventors disclosed a press pump, which includes a pump housing, a piston, a pump rod, and a pressing sleeve. The pump housing has a pumping chamber, and the piston is located in the pumping chamber and connected to the inner wall of the pumping chamber. The first end of the pump rod is connected to the piston, and the pressing sleeve is fitted around the outer periphery of the second end of the pump rod. A relatively movable gap is formed between the inner periphery of the pressing sleeve and the outer periphery of the pump rod. The pressing sleeve and the pump rod are interlocked to achieve bidirectional linkage along the length of the pump rod. In the press pump of the prior art, the pump housing is integral, which results in the volume of the pumping chamber being fixed after the pump housing is formed. That is, when the press pump is pressed, the amount of fluid that the press pump can pump is fixed. However, users have different needs for different fluid volumes. To match different fluid volumes, the current practice is to produce press pumps with different pump chamber volumes. This not only increases material costs and storage and transportation costs, but also fails to quickly meet customers' needs for press pumps that can pump different fluid volumes.

[0038] Refer to the accompanying drawings of the specification of this utility model. Figures 1 to 17 A preferred embodiment of the present invention will be disclosed and described in the following description, wherein the fluid container includes a press pump 100 and a bottle body 200, the press pump 100 being mounted on the bottle body 200 for pumping out fluids such as emulsions contained in the bottle space 201 of the bottle body 200, wherein the press pump 100 includes a pump core assembly 10 and a pump head assembly 20, the pump core assembly 10 being mounted on the bottom of the pump head assembly 20, and the pump head assembly 20 being configured to be mounted on the bottle body 200 to mount the press pump 100 on the bottle body 200.

[0039] Reference Appendix Figures 1 to 6 , Figures 14 to 17 The pump core assembly 10 includes a pump core housing 11, a bottom valve body 12, a piston 13, a top valve body 14, and a connecting pipe 15.

[0040] Specifically, the pump housing 11 has a pump core cavity 111 and a bottom inlet port 112 communicating with the pump core cavity 111. The bottom valve body 12 is installed at the bottom of the pump core cavity 111 of the pump housing 11 and is configured to open and close the bottom inlet port 112 of the pump housing 11. When the bottom valve body 12 opens the bottom inlet port 112 of the pump housing 11, fluids such as emulsions in the bottle space 201 of the bottle body 200 are allowed to flow from the bottom inlet port 112 of the pump housing 11 into the pump core cavity 111 of the pump housing 11. When the bottom valve body 12 closes the bottom inlet port 112 of the pump housing 11, fluids such as emulsions in the pump core cavity 111 of the pump housing 11 are prevented from flowing back into the bottle space 201 of the bottle body 200.

[0041] It is worth mentioning that the specific type of the bottom valve body 12 is not limited in the fluid container of this utility model. (See attached...) Figures 1 to 17 In a specific example of the fluid container of the present invention shown, the bottom valve body 12 is a ball that opens and closes the bottom inlet hole 112 of the pump core housing 11 by moving up and down.

[0042] Reference Appendix Figure 1 and Figure 2 The piston 13 is movably mounted vertically in the pump core cavity 111 of the pump core housing 11. The piston 13 has a piston hole 131. The top valve body 14 is mounted on the piston 13 and configured to open and close the piston hole 131 of the piston 13. When the top valve body 14 opens the piston hole 131 of the piston 13, fluids such as emulsions in the pump core cavity 111 of the pump core housing 11 are allowed to flow through the piston hole 131 of the piston 13. When the top valve body 14 closes the piston hole 131 of the piston 13, fluids such as emulsions in the pump core cavity 111 of the pump core housing 11 are prevented from flowing through the piston hole 131 of the piston 13.

[0043] It is worth noting that the specific type of the top valve body 14 is not limited in the fluid container of this utility model. (See attached...) Figures 1 to 17 In this specific example of the fluid container of the present invention shown, the top valve body 14 is a diaphragm valve, which includes a valve plate 141, a mounting ring 142 surrounding the valve plate 141, and at least one deformable connecting arm 143 connecting the valve plate 141 and the mounting ring 142. The top valve body 14 opens and closes the piston hole 131 of the piston 13 by the up-and-down movement of the valve plate 141. When the valve plate 141 moves upward to open the piston hole 131 of the piston 13, the valve plate 141 pulls the connecting arm 143 to deform. When the connecting arm 143 returns to its initial state, the connecting arm 143 pulls the valve plate 141 downward to close the piston hole 131 of the piston 13.

[0044] It is worth mentioning that the mounting method of the top valve body 14 and the piston 13 is not limited in the fluid container of this utility model. For example, in the appendix Figures 1 to 17 In this specific example of the fluid container of the present invention shown, the piston 13 has a piston mounting groove 132 with a top opening, and the mounting ring 142 of the top valve body 14 is mounted on the inner wall of the piston 13 that defines the piston mounting groove 132 to mount the top valve body 14 to the piston 13, and the top valve body 14 is received in the piston mounting groove 132 of the piston 13.

[0045] The connecting pipe 15 has a first pipe hole 151, and the bottom of the connecting pipe 15 is inserted into the piston mounting groove 132 of the piston 13 to prevent the top valve body 14 from falling off the piston 13. Preferably, the connecting pipe 15 presses against the mounting ring 142 of the top valve body 14, thereby ensuring that the top valve body 14 is reliably mounted on the piston 13.

[0046] Reference Appendix Figures 1 to 17 The pump head assembly 20 includes a pump head housing 21, a pressing head 22, a discharge pipe 23, an elastic element 24, and a locking cap 25. The pump head housing 21 has a pump head cavity 211 and a retaining ring 212 located within the pump head cavity 211. The retaining ring 212 has an annular hole 2121. The pressing head 22 has a cap channel 221. The discharge pipe 23 has a second pipe hole 231. The discharge pipe 23 is located in the pump head cavity 211 of the pump head housing 21, and the bottom of the discharge pipe 23 passes through the annular hole 2121 of the retaining ring 212. The top of 23 is mounted on the pressing head 22, the head cap channel 221 of the pressing head 22 is connected to the second tube hole 231 of the discharge tube 23, wherein the elastic element 24 is fitted in the middle of the discharge tube 23, the bottom of the elastic element 24 abuts against the abutment ring 212 of the pump head housing 21, and the top of the elastic element 24 is set to remain stationary relative to the discharge tube 23, wherein the locking cap 25 is fitted in the top of the discharge tube 23 and fixedly mounted on the top of the pump head housing 21 to prevent the discharge tube 23 from detaching upward from the pump head housing 21.

[0047] In the appendix Figures 1 to 17 In this specific example of the fluid container of the present invention shown, the top of the pump core housing 11 is mounted on the bottom of the pump head housing 21, the top of the connecting pipe 15 is mounted on the bottom of the discharge pipe 23, and the first pipe hole 151 of the connecting pipe 15 and the second pipe hole 231 of the discharge pipe 23 are connected to install the pump core assembly 10 on the bottom of the pump head assembly 20, thereby realizing the assembly of the push pump 100.

[0048] As needed, the pump core assembly 10 with pump core chambers 111 of different volumes can be assembled to the pump head assembly 20, thus quickly obtaining the press pump 100 capable of pumping different flow rates. For example, refer to the attached... Figure 3The pump core assembly 10, with its large-volume pump core cavity 111, can be mounted on the pump head assembly 20. Thus, after the press pump 100 is mounted on the bottle body 200, the user can pump out a larger amount of fluid each time they press the press head 22 of the press pump 100. (Refer to the attached diagram.) Figure 4 The pump core assembly 10, which has a small volume pump core cavity 111, can be installed on the pump head assembly 20, so that after the press pump 100 is installed on the bottle body 200, the user can pump out a smaller amount of fluid each time the press head 22 of the press pump 100 is pressed.

[0049] Specifically, when the user presses the pressing head 22, the pressing head 22, the discharge pipe 23, the connecting pipe 15, and the piston 13 move downward to compress the space of the pump core cavity 111 of the pump core housing 11, resulting in an increase in pressure within the pump core cavity 111. The bottom valve body 12 remains closed to the bottom liquid inlet 112 of the pump core housing 11, while the top valve body 14 opens the piston hole 131 of the piston 13. The emulsion and other fluids in the pump core cavity 111 of the pump core housing 11 flow sequentially through the piston hole 131 of the piston 13, the first pipe hole 151 of the connecting pipe 15, the second pipe hole 231 of the discharge pipe 23, and the head cap channel 221 of the pressing head 22 to pump out the emulsion and other fluids. At this time, the elastic element 24 is compressed and accumulates elastic potential energy. After the pressing head 22 is released, the elastic element 24 pushes the pressing head 22, the discharge pipe 23, the connecting pipe 15 and the piston 13 upward during the process of returning to the initial state. The bottom valve body 12 opens the bottom inlet hole 112 of the pump core housing 11 and the top valve body 14 closes the piston hole 131 of the piston 13. The emulsion and other fluids in the bottle space 201 of the bottle body 200 enter the pump core cavity 111 through the bottom inlet hole 112 of the pump core housing 11. After the pressure in the pump core cavity 111 of the pump core housing 11 and the pressure in the bottle space 201 of the bottle body 200 are restored to equilibrium, the bottom valve body 12 closes the bottom inlet hole 112 of the pump core housing 11.

[0050] Reference Appendix Figures 1 to 6 The pump core assembly 10 also includes a suction tube 16, the top of which is installed at the bottom of the pump core housing 11, and the bottom of which can extend into the interior of the bottle space 201 of the bottle body 200 to ensure that the emulsion or other fluids at the bottom of the bottle space 201 of the bottle body 200 can enter the pump core cavity 111 of the pump core housing 11.

[0051] Reference Appendix Figures 3 to 6The pump head housing 21 has at least one convex ring 213 and at least one outwardly protruding rib 214. The convex ring 213 and the outwardly protruding rib 214 are formed at the bottom of the pump head housing 21 in a mutually perpendicular intersecting manner. The convex ring 213 extends circumferentially along the bottom of the pump head housing 21, and the outwardly protruding rib 214 extends vertically along the bottom of the pump head housing 21. Correspondingly, the pump core housing 11 has at least one annular groove 113 and at least one rib groove 114. The rib groove 114 and the annular groove 113 are formed perpendicularly intersecting on the inner wall of the top of the pump core housing 11. The annular groove 113 of the pump core housing 11 matches the convex ring 213 of the pump head housing 21, and the rib groove 114 of the pump core housing 11 matches the outwardly protruding rib 214 of the pump head housing 21. When the bottom of the pump head housing 21 is inserted into… When the pump core housing 11 is in the cavity of the pump core chamber 111, each of the protruding rings 213 of the pump head housing 21 is respectively engaged in the annular grooves 113 of the pump core housing 11 to prevent the pump core housing 11 from detaching from the bottom of the pump head housing 21. At the same time, each of the protruding ribs 214 of the pump head housing 21 is respectively engaged in the rib grooves 114 of the pump core housing 11 to prevent the pump core housing 11 from rotating relative to the pump head housing 21, thus ensuring that the pump core housing 11 is firmly installed on the pump head housing 21. In this utility model, the number of protruding rings 213 in the pump head housing 21 and the number of annular grooves 113 in the pump core housing 11 are both multiple. Each of the protruding rings 213 in the pump head housing 21 is respectively inserted into each of the annular grooves 113 in the pump core housing 11. The number of protruding ribs 214 in the pump head housing 21 and the number of rib grooves 114 in the pump core housing 11 are both multiple. Each of the protruding ribs 214 in the pump head housing 21 is respectively inserted into each of the rib grooves 114 in the pump core housing 11.

[0052] Optionally, in the appendix Figure 18 In this specific example of the press pump 100 of the fluid container of the present invention, the top of the pump core housing 11 is screwed to the bottom of the pump head housing 21 to mount the pump core assembly 10 on top of the pump head assembly 20.

[0053] Reference Appendix Figures 1 to 6 The pump head assembly 20 of the press pump 100 further includes a toothed sleeve 26, which is fitted onto the top of the pump head housing 21. The toothed sleeve 26 can be screwed onto the bottle mouth of the bottle body 200 to install the press pump 100 onto the bottle body 200.

[0054] Continue to refer to the appendix Figures 1 to 17The press pump 100 of the fluid container of this utility model has a locked state and an unlocked state. The press pump 100 is configured to switch from the locked state to the unlocked state. When the press pump 100 is in the locked state, the press pump 100 is prevented from being pressed. When the press pump 100 is in the unlocked state, the press pump 100 is allowed to be pressed to pump out fluids such as emulsions from the bottle space 201 of the bottle body 200.

[0055] Specifically, see the attached document. Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 12 and Figure 13 The pump head assembly 20 includes a guide seat 27, which has at least one helical groove 271, at least one abutment 272, and at least one limiting wing 273. The helical groove 271 is disposed on the inner wall of the guide seat 27 and extends along the height direction of the guide seat 27. The abutment 272 is disposed at the top of the helical groove 271, and the limiting wing 273 protrudes from the outer wall of the guide seat 27. (See attached diagram) Figure 1 and Figure 2 The pump head housing 21 has at least one limiting groove 215, which is located on the inner wall of the pump head housing 21 and extends along the height direction of the pump head housing 21. The guide seat 27 is movably mounted in the pump head cavity 211 of the pump head housing 21. The limiting wing 273 of the guide seat 27 protrudes into the limiting groove 215 of the pump head housing 21 to prevent the guide seat 27 from rotating relative to the pump head housing 21. The top of the elastic element 24 abuts against the guide seat 27. (See attached diagram) Figures 5 to 11 The locking cap 25 has a spiral abutment surface 251, a relief groove 252, and a locking groove 253. The relief groove 252 extends upward from the abutment surface 251, and the locking groove 253 is located at the bottom of the abutment surface 251. The discharge pipe 23 has at least one protrusion 232, a pipe ring 233, and an abutment post 234. The guide seat 27 is fitted onto the discharge pipe 23. The protrusion 232 of the discharge pipe 23 protrudes into the spiral groove 271 of the guide seat 27, and the protrusion 232 can rest against the support platform 272 after sliding to the top of the spiral groove 271.

[0056] When the press pump 100 is in the locked state, the top of the abutment post 234 of the discharge pipe 23 abuts against the abutment surface 251 of the lock cap 25 and is locked into the slot 253 of the lock cap 25. At this time, the protrusion 232 of the discharge pipe 23 is located at the bottom of the spiral groove 271 of the guide seat 27. When unlocking is required, the pressing head 22 and the discharge tube 23 are rotated in one direction, causing the top of the abutment post 234 of the discharge tube 23 to disengage from the slot 253 of the lock cap 25. The top of the abutment post 234 slides along the abutment surface 251 of the lock cap 25, and the protrusion 232 of the discharge tube 23 slides along the spiral groove 271 of the guide seat 27. At the same time, the protrusion 232 of the discharge tube 23 pushes the guide seat 27 downward, and the guide seat 27 compresses the elastic element 24 toward the abutment ring 212 of the pump head housing 21, so that the elastic element 24 is compressed and deformed to accumulate elastic potential energy. After the pressing head 22 and the discharge pipe 23 rotate to the position where the top of the abutment post 234 of the discharge pipe 23 corresponds to the clearance groove 252 of the lock cap 25, on the one hand, the protrusion post 232 of the discharge pipe 23 slides to the top of the spiral groove 271 of the guide seat 27 and rests against the abutment platform 272. On the other hand, during the process of restoring the initial state, the elastic element 24 pushes the guide seat 27, the discharge pipe 23 and the pressing head 22 upward, so that the tube ring 233 of the discharge pipe 23 abuts against the abutment surface 251 of the lock cap 25 and the abutment post 234 protrudes into the clearance groove 252 of the lock cap 25. At this time, the pressing pump 100 is in the unlocked state. It is understood that when the press pump 100 is in the unlocked state, the protrusion 232 of the discharge pipe 23 rests against the abutment 272 of the guide seat 27, the relative position of the discharge pipe 23 and the guide seat 27 remains unchanged, and the top of the elastic element 24 abuts against the guide seat 27. Therefore, the top of the elastic element 24 is set to remain stationary relative to the discharge pipe 23.

[0057] In other words, after unlocking, the protrusion 232 of the discharge pipe 23 rests against the abutment 272 of the guide seat 27. When the user presses the pressing head 22, the pressing head 22, the discharge pipe 23, the connecting pipe 15, the piston 13, and the guide seat 27 move downward to compress the space of the pump core cavity 111 of the pump core housing 11, causing the pressure inside the pump core cavity 111 to increase. The bottom valve body 12 remains closed to the pump core housing 11. With the bottom inlet hole 112 opened and the top valve body 14 opened the piston hole 131 of the piston 13, the emulsion and other fluids in the pump core cavity 111 of the pump core housing 11 flow sequentially through the piston hole 131 of the piston 13, the first pipe hole 151 of the connecting pipe 15, the second pipe hole 231 of the discharge pipe 23 and the head cap channel 221 of the pressing head 22 to pump out the emulsion and other fluids. At this time, the elastic element 24 is compressed and accumulates elastic potential energy. After the pressing head 22 is released, the elastic element 24 pushes the guide seat 27, the pressing head 22, the discharge pipe 23, the connecting pipe 15 and the piston 13 upward during the process of returning to the initial state. The bottom valve body 12 opens the bottom inlet hole 112 of the pump core shell 11 and the top valve body 14 closes the piston hole 131 of the piston 13. The emulsion and other fluids in the bottle space 201 of the bottle body 200 enter the pump core cavity 111 through the bottom inlet hole 112 of the pump core shell 11. After the pressure in the pump core cavity 111 of the pump core shell 11 and the pressure in the bottle space 201 of the bottle body 200 are restored to equilibrium, the bottom valve body 12 closes the bottom inlet hole 112 of the pump core shell 11.

[0058] In the appendix Figures 1 to 17 In this specific example of the fluid container of the present invention, the guide seat 27 has two spiral grooves 271 and two abutment platforms 272. Correspondingly, the discharge pipe 23 has two protrusions 232. The two protrusions 232 of the discharge pipe 23 protrude into the two spiral grooves 271 of the guide seat 27. After the two protrusions 232 of the discharge pipe 23 slide to the top of the two spiral grooves 271 of the guide seat 27, the two protrusions 232 of the discharge pipe 23 rest on the two abutment platforms 272 of the guide seat 27. At this time, when the pressing head 22 is pressed and the discharge pipe 23 is driven to move downward by the pressing head 22, the discharge pipe 23 can apply pressure to the guide seat 27 on the opposite sides of the guide seat 27. In this way, the opposite sides of the guide seat 27 can be evenly stressed, avoiding tilting, so as to ensure that the pressing head 22 is pressed smoothly.

[0059] In the appendix Figures 1 to 17 In this specific example of the fluid container of the present invention shown, the guide seat 27 has two limiting wings 273, and correspondingly, the pump head housing 21 has two limiting grooves 215. The two limiting wings 273 of the guide seat 27 protrude into the two limiting grooves 215 of the pump head housing 21, and the top of the elastic element 24 abuts against the two limiting wings 273 of the guide seat 27. In this way, when the guide seat 27 compresses the elastic element 24 in the direction of the abutment ring 212 of the pump head housing 21, the situation of the elastic element 24 being subjected to force on one side can be avoided, so that the elastic element 24 can be stably deformed in the height direction.

[0060] Preferably, in the appendix Figures 1 to 17 In this specific example of the fluid container of the present invention shown, the elastic element 24 is a plastic spring, which facilitates the complete plasticization of the press pump 100. Alternatively, in other feasible examples of the fluid container of the present invention, the elastic element 24 may be a metal spring.

[0061] Appendix Figure 19 Another specific example of the press pump 100 of the fluid container of the present invention is shown, with reference to the appendix. Figures 1 to 17 The difference between the push-pump 100 of the fluid container shown in this utility model and the one attached is that... Figure 19 In the specific example of the press pump 100 shown, the pump core assembly 10 does not have the connecting pipe 15. When the pump core assembly 10 is installed on the pump head assembly 20, the bottom of the discharge pipe 23 of the pump head assembly 20 is inserted into the piston mounting groove 132 of the piston 13. After the top valve body 14 opens the piston hole 131 of the piston 13, the emulsion or other fluid in the pump core cavity 111 of the pump core housing 11 is allowed to enter the second pipe hole 231 of the discharge pipe 23 through the piston hole 131 of the piston 13, and then be discharged through the cap channel 221 of the press head 22. In this way, the press pump 100 pumps the emulsion or other fluid in the bottle space 201 of the bottle body 200.
