Diaphragm plate, diaphragm plate assembly, booster pump head, and booster pump
TECHNICAL FIELD
The present invention relates to the field of diaphragm booster pumps, and in particular to a diaphragm plate, a diaphragm plate assembly, a booster pump head, and a booster pump.
BACKGROUND ART
At present, diaphragm booster pumps are often used in reverse osmosis water filters. For example, the
Chinese patent publication No. CN 213419314 U discloses a booster pump head and a diaphragm pump using the booster pump head, the booster pump head comprising a pump head seat, a diaphragm plate, a balance wheel seat, a piston push plate, a piston valve seat and a pump head cover, which are sequentially arranged from bottom to top, the piston push plate being embedded into the diaphragm plate, the piston push plate being further connected to a connecting protruding post, the balance wheel seat being provided with several balance wheels, each balance wheel being provided with a connecting channel for plugging of the connecting protruding post, the balance wheel is provided with a threaded connection member in a penetrating manner, and the threaded connection member is connected and fixed to the connecting protruding post.
In the solution disclosed in this patent, the connecting protruding posts are embedded into the diaphragm plate, and then fixing screws pass through the balance wheels from one side of the balance wheel seat and are connected to the connecting protruding posts. However, this method has the following problems.
Firstly, it is inconvenient to disassemble. When the diaphragm plate needs to be disassembled, the balance wheel seat needs to be disassembled at first, then the threaded connection member can be unscrewed from one side of the balance wheel seat, and then the diaphragm plate can be removed.
Secondly, the connecting protruding post protrudes a certain length from the diaphragm plate and then can be connected to the balance wheels. After a long time of use, the part of the connecting protruding post that protrudes from the diaphragm plate will be worn, and the connecting protruding post will become loose at the position in contact with the diaphragm plate. Also, such a mounting method will cause the connecting protruding posts to be too long, so that the overall height after assembled will too large, which cannot adapt to the mounting environment of small space.
Therefore, the pump head needs to be improved to facilitate production and assembly.
SUMMARY OF THE INVENTION
In order to solve the above technical problems, a first objective of the present invention is to provide a diaphragm plate. The diaphragm plate is provided with mounting holes and protruding posts to facilitate the subsequent mounting of piston push members in the diaphragm plate, and threaded connection members pass through the diaphragm plate from the side provided with the mounting holes such that the diaphragm plate, the piston push members and a balance wheel seat are mounted together, which reduces the overall size after mounted and also enables the diaphragm plate to be assembled and disassembled more conveniently.
In order to achieve the above objective of the present invention, the present invention uses the technical solution as follows: a diaphragm plate, wherein one side of the diaphragm plate is provided with several axially extending protruding structures, an end face of the protruding structure being provided with a mounting hole, and the protruding structure being internally provided with a first cavity in communication with the mounting hole; and the other opposite side of the diaphragm plate is provided with several protruding posts, each of the protruding structures being arranged corresponding to one of the protruding posts, and the protruding post being axially provided with a second cavity in communication with the first cavity.
Preferably, the internal diameter of the first cavity is greater than that of the second cavity, and the internal diameter of the first cavity 1s greater than that of the mounting hole.
Preferably, an annular snap ring 1s provided at the mounting hole, and the annular snap ring axially extends toward the first cavity such that a snap-fitting gap is formed between an outer wall of the annular snap ring and an inner wall of the first cavity.
On the basis of the same concept of the present invention, a second objective of the present invention is to provide a diaphragm plate assembly. The piston push heads and the connecting posts of the piston push members are respectively embedded into first cavities and second cavities such that the piston push members are disposed in a diaphragm plate, and the connecting posts of the piston push members are completely surrounded by the protruding posts, thereby reducing the height of the entire diaphragm plate assembly.
In order to achieve the above objective of the present invention, the present invention uses the technical solution as follows:
a diaphragm plate assembly, comprising: a diaphragm plate, which 1s a diaphragm plate according to any of the aspects described above; and piston push members, each of which is provided with an axially extending through-channel, with an upper end of the piston push member being embedded into the first cavity of the protruding structures, and the other end of the piston push member being embedded into the second cavity of the protruding post. The internal diameter of the first cavity is greater than that of the second cavity, and the internal diameter of the first cavity is greater than that of the mounting hole, so that it is ensured that the piston push members can be securely snap-fitted on the diaphragm plate.
Preferably, the piston push member comprises a piston push head and a connecting post connected to one side of the piston push head, the through-channel penetrating the piston push head and the connecting post, the piston push head being embedded into the first cavity, and the connecting post being embedded into the second cavity.
With such a configuration, the piston push members can be completely disposed in the diaphragm plate such that the connecting posts of the piston push members are completely surrounded by the protruding posts, which reduces the height of the entire diaphragm plate assembly.
In addition, the following problem can be solved. The connecting post of the piston push member protrudes from the protruding post and is then connected to a balance wheel seat, so that after a long time of use, when the part of the connecting post of the piston push member that protrudes from the protruding post receives a transverse force applied by the end portion of the protruding post, the part of the connecting post that protrudes from the protruding post is worn, and the connecting post of the piston push member will become loose at the position in contact with the end portion of the protruding post. Also,
the connecting post is completely disposed in the second cavity, which can reduce the length of the connecting post.
Preferably, the piston push head and the connecting post are integrally formed. 5 Preferably, an end face of the piston push head is provided with an annular raised ring, and the annular raised ring is disposed in the first cavity.
Preferably, the annular raised ring is configured to be snap-fitted in a snap-fitting gap formed between an outer wall of the annular snap ring on the diaphragm plate and an inner wall of the first cavity. With such a configuration, it is possible to ensure that the piston push head can be securely mounted in the first cavity, which thus improves the stability of connection between the piston push member and the diaphragm plate.
Preferably, the annular raised ring is provided with several process grooves. The function of providing the process grooves is to facilitate venting and can further improve the connection strength.
On the basis of the same concept of the present invention, a third objective of the present invention is to provide a booster pump head. The protruding post of the diaphragm plate is fixed in a balance wheel from one side of the diaphragm plate by means of a threaded rod portion of a threaded connection member, which allows the diaphragm plate to be assembled and disassembled more conveniently and can also reduce the height of the entire booster pump head.
In order to achieve the above objective of the present invention, the present invention uses the technical solution as follows: a booster pump head, comprising a balance wheel seat, a pump head seat, a piston valve seat and a pump head cover, and further comprising threaded connection members and a diaphragm plate assembly according to any of the aspects described above, the balance wheel seat being provided with several balance wheels, each balance wheel being provided with a plug-in socket for plugging of the protruding post on the diaphragm plate in the diaphragm plate assembly, and the threaded connection member passing through the through-channel and being then connected and fixed to the balance wheel.
Preferably, the balance wheel is provided with a threaded connection hole at the bottom of the plug-in socket, and a threaded rod portion of the threaded connection member passes through the through-channel and is then connected to the threaded connection hole, so that the diaphragm plate assembly is connected to the balance wheel seat.
With such a configuration, the threaded rod portion of the threaded connection member sequentially passes through the mounting hole, the through-channel and the threaded connection hole from one side of the diaphragm plate such that the threaded connection member is screwed in the threaded connection hole, and then the protruding post is fixed in the balance wheel, which is convenient to mount. In addition, the threaded connection member receives the force that is applied in the axial direction thereof, and is good in receiving force, which is conducive to maintaining the connection stability. If the threaded connection member is laterally connected to the connecting protruding post, the threaded connection member receives the force that is not applied in the axial direction thereof so as to generate, in the direction perpendicular to the axial direction, a shear force that bends or even breaks the threaded connection member.
Also, the threaded connection member passes through the piston push member from one side of the diaphragm plate and is then connected to the threaded connection hole, which thus avoids the problem of inconvenient assembly and disassembly caused by mounting the threaded connection member from the back side.
Preferably, the balance wheel is provided with a protruding portion at the bottom of the plug-in socket, and
: the threaded connection hole extends from the end face of the protruding portion in a direction that faces away from the plug-in socket and the diaphragm plate. Also, the end of the protruding post of the diaphragm plate that faces toward the bottom of the plug-in socket is provided with a plugging hole that matches with the protruding portion, with the diameter of the plugging hole being greater than that of the through-channel in the piston push member. With such a configuration, the plugging hole and the protruding portion can be positioned by snap-fitting, thereby ensuring the coaxiality of the balance wheel and the piston push member after assembled, so that the through-channel and the threaded connection hole maintain the coaxiality when in communication, which facilitates the subsequent connection and fixing of the threaded connection member.
Preferably, the side of the diaphragm plate that faces toward the balance wheel seat is provided with a spacer, the spacer is provided with an assembly hole for the protruding post to pass through, and the spacer is closely attached to the side of the diaphragm plate that faces toward the balance wheel seat.
With such a configuration, the spacer can function to prevent wear between the diaphragm plate and the balance wheel seat. Since the balance wheel seat will drive the diaphragm plate to move together during the long- term rotation, and the contact surface between the balance wheel seat and the diaphragm plate will experience fatigue wear after a long time of use, which will cause fatigue damage on the diaphragm plate, the spacer can have a good anti-wear function between the balance wheel seat and the diaphragm plate and facilitate the assembly, disassembly and replacement.
Preferably, the protruding post on the diaphragm plate has a circular cross-section. Such a configuration facilitates plugging of the protruding post into the plug- in socket in the balance wheel seat.
Preferably, the protruding post on the diaphragm plate has a non-circular cross-section. Specifically, the protruding post may have a cross-section in the shape of square, rectangle, ellipse, or other shape. With such a configuration, the rotation of the protruding post around its own center can be effectively reduced during mounting, which facilitates fixing of the protruding post to the balance wheel.
On the basis of the same concept of the present invention, a fourth objective of the present invention is to provide a booster pump, comprising a booster pump head according to any of the aspects described above, an eccentric cam, and a drive motor, the eccentric cam being mounted in the booster pump head, and the drive motor being connected to the eccentric cam and driving the eccentric cam to rotate.
Compared with the prior art, the present invention has the beneficial technical effects as follows. 1. The diaphragm plate is provided with mounting holes and protruding posts to facilitate the subsequent mounting of piston push members in the diaphragm plate, and threaded connection members pass through the diaphragm plate from the side having the mounting holes such that the diaphragm plate, the piston push members and a balance wheel seat are mounted together, which reduces the overall size after mounted and also enables the diaphragm plate to be assembled and disassembled more conveniently. 2. The piston push heads and the connecting posts of the piston push members are respectively embedded into the first cavities and the second cavities such that the piston push members are disposed in the diaphragm plate, and the connecting posts of the piston push members are completely surrounded by the protruding posts, which reduces the height of the entire diaphragm plate assembly and avoids the problem of wear caused by the connecting posts of the piston push members protruding {from the protruding posts and then being connected to the balance wheel seat. 3. The protruding post of the diaphragm plate is fixed in a balance wheel from one side of the diaphragm plate by means of a threaded rod portion of a threaded connection member, which allows the diaphragm plate to be assembled and disassembled more conveniently and can also reduce the height of the entire booster pump head. 4. The side of the diaphragm plate that faces toward the balance wheel seat is provided with the spacer, so that the spacer can function to prevent wear between the diaphragm plate and the balance wheel seat.

DETAILED DESCRIPTION OF EMBODIMENTS
In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments, but the scope of protection of the present invention is not limited to the specific examples described below.
Examples
Example 1
Referring to Figs. 1-5, in a diaphragm 1, one side of the diaphragm plate 1 is provided with several axially extending protruding structures 11, with an end face of each protruding structure 11 being provided with a mounting hole 111, and the protruding structure 11 being internally provided with a first cavity 13 in communication with the mounting hole 111; and the other opposite side of the diaphragm plate 1 is provided with several protruding posts 12, each of the protruding structures 11 being arranged corresponding to one of the protruding posts 12, each of the protruding structures 11 having the same central axis as the corresponding protruding post 12, and the protruding post 12 being axially provided with a second cavity 121 in communication with the first cavity 13. One or more protruding structures 11 and one or more protruding posts 12 are provided, four protruding structures and four protruding posts are provided in this example, and the number of the protruding structures 11 and the number of the protruding posts can be increased or reduced according to the actual environment of use.
The internal diameter of the first cavity 13 is greater than that of the second cavity 121, and the internal diameter of the first cavity 13 is greater than that of the mounting hole 111. An annular snap ring 14 is provided at the mounting hole 111, and the annular snap ring 14 axially extends toward the first cavity 13 such that a snap-fitting gap 131 is formed between an outer wall of the annular snap ring 14 and an inner wall of the first cavity 13. The diaphragm plate 1 is provided with mounting holes 111 and protruding posts 12 to facilitate the subsequent mounting of piston push members 2 in the diaphragm plate 1, and threaded connection members 4 pass through the diaphragm plate 1 from the side having the mounting holes 111 such that the diaphragm plate 1, the piston push members 2 and a balance wheel seat 3 are mounted together, which reduces the overall size after mounted and also enables the diaphragm plate 1 to be assembled and disassembled more conveniently. In addition, the snap-fitting gap 131 can provide a snap-fitting space subsequently for the piston push head 21 of the piston push member 2.
Example 2
Referring to Figs. 5-7, a diaphragm plate assembly comprises: a diaphragm plate 1 and piston push members 2. The diaphragm plate 1 is a diaphragm plate 1 according to the example described above. The number of the piston push members 2 is the same as the number of the protruding structures 11 and the number of the protruding posts 12, each piston push member 2 is provided with an axially extending through-channel 23, an upper end of the piston push member 2 is embedded into the first cavity 13 of the protruding structure 11, and the other end of the piston push member 2 is embedded into the second cavity 121 of the protruding post 12.
The piston push member 2 comprises a piston push head 21 and a connecting post 22 connected to one side of the piston push head 21, the through-channel 23 penetrating the piston push head 21 and the connecting post 22, the piston push head 21 being embedded into the first cavity 13, and the connecting post 22 being embedded into the second cavity 121. The internal diameter of the first cavity 13 is greater than that of the second cavity 121, and the internal diameter of the first cavity 13 is greater than that of the mounting hole 111, so that it is ensured that the piston push head 21 can be securely snap-fitted on the diaphragm plate 1. The piston push heads 21 and the connecting posts 22 of piston push members 2 are respectively embedded into the first cavities 13 and the second cavities 121 such that the piston push members 2 are disposed in a diaphragm plate 1, and the connecting posts 22 of the piston push members 2 are completely surrounded by the protruding posts 12, thereby reducing the height of the entire diaphragm plate assembly. In addition, it is also possible to prevent the occurrence of the case where the connecting post 22 of the piston push member 2 protrudes from the protruding post 12 and is then connected to a balance wheel seat 3, so that after a long time of use, when the part of the connecting post 22 of the piston push member 2 that protrudes from the protruding post 12 receives a transverse force applied by the end portion of the protruding post 12, the part of the connecting post 22 that protrudes from the protruding post 12 is worn, and the connecting post 22 of the piston push member 2 will become loose at the position in contact with the end portion of the protruding post 12. Also, the connecting post 22 is completely disposed in the second cavity 121, which can reduce the length of the connecting post 22.
The piston push head 21 and the connecting post 22 are integrally formed. An end face of the piston push head 21 is provided with an annular raised ring, and the annular raised ring is disposed in the first cavity 13. The annular raised ring is configured to be snap-fitted in a snap-fitting gap 131 formed between an outer wall of the annular snap ring 14 on the diaphragm plate 1 and an inner wall of the first cavity 13. With such a configuration, it is possible to ensure that the piston push head 21 can be securely mounted in the first cavity 13, which thus improves the stability of connection between the piston push member 2 and the diaphragm plate 1.
The annular raised ring is provided with several process grooves 211. The function of providing the process grooves 211 is to facilitate venting and can further improve the connection strength.
Example 3
Referring to Figs. 8-13, a booster pump head sequentially comprises, from bottom to top, a balance wheel seat 3, a pump head seat 6, a piston valve seat 7 and a pump head cover 3, and further comprises threaded connection members 4 and a diaphragm plate assembly in the example described above between the balance wheel seat 3 and the piston valve seat 7. The balance wheel seat 3 is disposed on the pump head seat 6, the balance wheel seat 3 is provided with several balance wheels 31, the balance wheels 31 pass through the through-holes in the pump head seat 6 and is then connected to the diaphragm plate on the diaphragm plate assembly, each balance wheel 31 is provided with a plug-in socket 313 for plugging of the protruding post 12 on the diaphragm plate 1 in the diaphragm plate assembly, each threaded connection member 4 passes through the through-channel 23 in the piston push member 2 and is then connected and fixed to the balance wheel 31, the side of the pump head seat 6 that faces away from the pump head cover 1s provided with the pump head base 9, and the pump head base 2 is configured such that the balance wheel seat 3 is mounted between the pump head seat 6 and the pump head base 9.
The balance wheel 31 is provided with a threaded connection hole 312 at the bottom of the plug-in socket 313, and a threaded rod portion 41 of the threaded connection member 4 passes through the through-channel 23 and is then connected to the threaded connection hole 312 such that the diaphragm plate assembly is connected to the balance wheel seat 3.
The balance wheel 31 is provided with a protruding portion 311 at the bottom of the plug-in socket 313, and the threaded connection hole 312 extends from the end face of the protruding portion 311 in a direction that faces away from the plug-in socket 313 and the diaphragm plate 1. Also, the end of the protruding post 12 of the diaphragm plate 1 that faces toward the bottom of the plug- in socket 313 is provided with a plugging hole that matches with the protruding portion 311, with the diameter of the plugging hole being greater than that of the through- channel 23 in the piston push member 2. With such a configuration, the plugging hole and the protruding portion 311 can be positioned in a snap-fitting manner, thereby ensuring the coaxiality of the balance wheel 31 and the piston push member 2 after assembled, so that the through- channel 23 and the threaded connection hole 312 maintain the coaxiality when in communication, which facilitates the subsequent connection and fixing of the threaded connection member 4.
The side of the diaphragm plate 1 that faces toward the balance wheel seat 3 is provided with a spacer 5, the spacer 5 is provided with an assembly hole for the protruding post 12 to pass through, and the spacer 5 is closely attached to the side of the diaphragm plate 1 that faces toward the balance wheel seat 3. With such a configuration, the spacer 5 can function to prevent wear between the diaphragm plate 1 and the balance wheel seat 3.
Since the balance wheel seat 3 will drive the diaphragm plate 1 to move together during the long-term rotation, and the contact surface between the balance wheel seat and the diaphragm plate will experience fatigue wear after a long time of use, which will cause fatigue damage on the diaphragm plate 1, the spacer 5 can have a good anti-wear function between the balance wheel seat and the diaphragm plate and facilitate the assembly, disassembly and replacement.
The protruding post 12 on the diaphragm plate 1 has a circular cross-section. Such a configuration facilitates plugging of the protruding post 12 into the plug-in socket 313 in the balance wheel seat 3.
Alternatively, the protruding post 12 on the diaphragm plate 1 has a non-circular cross-section. Specifically, the protruding post 12 may have a cross-section in the shape of square, rectangle, ellipse, or other shape. With such a configuration, the rotation of the protruding post 12 around its own center can be effectively reduced during mounting, which facilitates fixing of the protruding post 12 to the balance wheel.
The mounting process of the booster pump head is as follows. During connection, firstly, the piston push member 2 is embedded into the diaphragm plate 1, with the mounting hole 111 in the diaphragm plate 1 being in communication with the hanging through-hole in the piston push member 2, and then the protruding post 12 on the diaphragm plate 1 is plugged into the plug-in socket 313 of the balance wheel, with the threaded connection hole 312 in the balance wheel being in communication with the through- channel 23. Then, the threaded rod portion 41 of the threaded connection member 4 sequentially passes through the mounting hole 111, the through-channel 23 and the threaded connection hole 312 from one side of the diaphragm plate 1, so that the threaded connection member 4 is screwed in the threaded connection hole 312, and then the protruding post 12 is fixed in the balance wheel, which is convenient to mount. In addition, the threaded connection member 4 receives the force that is applied in the axial direction thereof, and is good in receiving force, which is conducive to maintaining the connection stability. If the threaded connection member 4 is laterally connected to the connecting protruding post 12, the threaded connection member 4 receives the force that is not applied in the axial direction thereof so as to generate, in the direction perpendicular to the axial direction, a shear force that bends or even breaks the threaded connection member 4.
Also, the threaded connection member 4 passes through the piston push member 2 from one side of the diaphragm plate 1 and is then connected to the threaded connection hole 312, so that during the assembly or disassembly of the booster pump head, the threaded connection member 4 can be screwed or unscrewed from the front side only by opening the piston valve seat 7 and the pump head cover 8, which facilitates the assembly of the diaphragm plate 1 and the balance wheel seat 3 and avoids the problem of inconvenient assembly and disassembly caused by mounting the threaded connection member 4 from the back side. In addition, the mounting of the threaded connection member 4 from one side of the diaphragm plate 1 also avoids the problem of insecure sealing caused by the configuration of the through threaded connection hole 312 in the balance wheel seat 3. Also, the mounting of the threaded connection member 4 from one side of the diaphragm plate 1 can also prevent the connecting post 22 of the piston push member 2 from plugging into the plug-in socket 313, so that the connection between the diaphragm plate 1, the piston push member 2 and the balance wheel seat 3 can be completed only by increasing the length of the threaded connection member 4 without providing a piston push member 2 that is too long, which reduces the overall height of the diaphragm plate assembly and the balance wheel seat 3 after assembled, so as to achieve more compact overall structure and wider mounting range.
Example 4
