[0049] Currently in water purification equipment, water pumps are often needed to regulate the flow in water purification, cooling and heating modules. Whether the function of the water pump can be realized is closely related to its sealing. If the sealing of the water pump is not good, it will cause gas or liquid leakage, thereby reducing the performance of the water pump and may cause damage to other structures in the water purification equipment.

[0050] In view of this, the present invention provides a water pump 100 .

[0051] See also Figures 1 to 3In one embodiment of the present invention, the water pump 100 includes a valve seat 1, a pump cover 2 and a sealing member 3; the pump cover 2 is installed on the valve seat 1; the sealing member 3 is arranged between the valve seat 1 and the pump cover 2, and the sealing member 3 includes a first sealing portion 31; wherein, the valve seat 1 is provided with a first spacer 11 toward the pump cover 2, and the pump cover 2 is provided with a second spacer 21 toward the first spacer 11, and the second spacer 21 abuts the first sealing portion 31 against the first spacer 11, and the first sealing portion 31 has a flange 311, and the flange 311 covers the outer periphery of the first spacer 11 and / or the second spacer 21.

[0052] In the water purification equipment, the sealing of the water pump 100 is a key issue. In order to prevent leakage of gas or liquid, the present application sets a seal 3 between the valve seat 1 and the pump cover 2, adds the design of the first diaphragm 11 and the second diaphragm 21, so that the seal 3 can be more closely abutted between the diaphragms, thereby achieving a better sealing effect.

[0053] The valve seat 1 and the pump cover 2 are the main components of the water pump 100. The basic functions of the water pump 100 can be realized through the cooperation of the valve seat 1 and the pump cover 2. The seal 3 is a key component. The first sealing portion 31 covers the outer periphery of the separator through the flange 311, which further improves the sealing effect. The design of the first separator 11 and the second separator 21 enables the seal 3 to form a sealed space between the valve seat 1 and the pump cover 2, thereby preventing the leakage of gas or liquid. Among them, the first separator 11 and the second separator 21 are enclosed to form independent chambers inside and outside the separator, respectively. The first separator 11 and the second separator 21 may have a water inlet chamber 4a inside and a water outlet chamber 4b outside, or the first separator 11 and the second separator 21 may have a water outlet chamber 4b inside and a water inlet chamber 4a outside. No specific limitation is made here.

[0054] The water pump 100 in the present application is provided with a valve seat 1, a pump cover 2 and a seal 3, so that the water pump 100 can achieve a better sealing effect during use. Specifically, the valve seat 1 is provided with a first separator 11 toward the pump cover 2, and the pump cover 2 is provided with a second separator 21 toward the first separator 11. The second separator 21 abuts the first sealing portion 31 against the first separator 11, and the first sealing portion 31 has a flange 311, and the flange 311 covers the outer periphery of the first separator 11 and / or the second separator 21. Among them, in this embodiment, the flange 311 only covers the outer periphery of the first separator 11. Of course, the flange 311 can also cover the outer periphery of the second separator 21. Secondly, the flange 311 can simultaneously cover the outer periphery of the first separator 11 and the second separator 21. The above embodiments are all optional embodiments of this embodiment. This design enables the seal 3 to fit more closely between the separators, thereby achieving a better sealing effect.

[0055] Compared with the prior art, the water pump 100 in the present application adds a first diaphragm 11 and a second diaphragm 21 so that the seal 3 can be more closely abutted between the first diaphragm 11 and the second diaphragm 21, thereby achieving a better sealing effect, avoiding liquid leakage, and improving the performance of the water pump 100.

[0056] The present application provides a seal 3 between the valve seat 1 and the pump cover 2, and adds the design of the first spacer 11 and the second spacer 21, so that the seal 3 can be more tightly abutted between the spacers, thereby achieving a better sealing effect. Specifically, the valve seat 1 is provided with a first spacer 11 toward the pump cover 2, and the pump cover 2 is provided with a second spacer 21 toward the first spacer 11. The second spacer 21 abuts the first sealing portion 31 against the first spacer 11, and the first sealing portion 31 has a flange 311, and the flange 311 covers the outer periphery of the first spacer 11 and / or the second spacer 21. Therefore, through this design, the sealing performance of the water pump 100 is improved, and the leakage of gas or liquid is avoided, thereby improving the overall performance of the water pump 100.

[0057] The technical solution of the present invention adopts a design in which a seal 3 is provided between the valve seat 1 and the pump cover 2, and a first partition 11 and a second partition 21 are added, so that the seal 3 can be more closely abutted between the two partitions, and a flange 311 is provided between the first partition 11 and the second partition 21, and the flange 311 covers the outer periphery of the first partition 11 and / or the second partition 21. Through this design, the sealing performance of the water pump 100 is improved, and leakage of gas or liquid is avoided, thereby improving the overall performance of the water pump 100.

[0058] Further, in one embodiment, see Figure 4 and Figure 5 The sealing member 3 further includes a second sealing portion 32 and a connecting rib 33 . The second sealing portion 32 is connected to the first sealing portion 31 via the connecting rib 33 . The second sealing portion 32 is disposed on the outer side of the first sealing portion 31 .

[0059] This design is intended to solve the sealing problem of the water pump 100. By adding a second sealing part 32 outside the first sealing part 31 and connecting the two through a connecting rib 33, the overall sealing effect of the water pump 100 can be enhanced. The first sealing part 31 is mainly responsible for sealing with the first partition 11 and the second partition 21, while the second sealing part 32 further enhances the overall sealing performance. This double sealing structure effectively prevents the leakage of gas or liquid, thereby improving the performance of the water pump 100 and protecting other structures in the water purification equipment.

[0060] The design of the second sealing portion 32 and the connecting rib 33 provides a variety of implementation methods. Specifically, the second sealing portion 32 and the connecting rib 33 can be made of elastic materials such as rubber and silicone to ensure that they can still maintain a good sealing effect under high pressure. In addition, the number and distribution of the connecting ribs 33 can be adjusted according to actual needs to achieve the best sealing effect. For example, the connecting ribs 33 can be evenly distributed between the first sealing portion 31 and the second sealing portion 32, or the number of connecting ribs 33 can be increased at a specific position to enhance the local sealing performance.

[0061] The advantage of this double sealing structure is that it can significantly improve the sealing performance of the water pump 100, prevent gas or liquid leakage, and ensure the normal operation of the water pump 100. Compared with the prior art, the design of the present application provides a more reliable and efficient sealing solution by adding a second sealing portion 32 and a connecting rib 33, effectively solving the problem of poor sealing of the water pump 100.

[0062] In one embodiment, see Figure 3 The pump cover 2 is provided with a first annular platform 22 facing the valve seat 1 , and the valve seat 1 is provided with a second annular platform 12 facing the pump cover 2 . The second sealing portion 32 abuts between the first annular platform 22 and the second annular platform 12 .

[0063] In the present application, the pump cover 2 and the valve seat 1 further enhance the sealing effect by providing the first ring platform 22 and the second ring platform 12 on the opposite surfaces thereof. The second sealing portion 32 is designed to abut between the first ring platform 22 and the second ring platform 12, thereby forming a more reliable sealing structure between the pump cover 2 and the valve seat 1. This design not only improves the sealing performance of the water pump 100, but also effectively prevents liquid or gas leakage, thereby improving the overall performance of the water pump 100.

[0064] Specifically, the arrangement of the first ring platform 22 and the second ring platform 12 enables the second sealing portion 32 to form a close contact surface between the two ring platforms. In this way, the water pump 100 can better maintain the internal pressure during operation and avoid performance degradation caused by poor sealing. This design is not only applicable to the water pump 100 in the water purification equipment, but also can be applied to other occasions requiring high sealing performance.

[0065] It can be seen that the technical solution provided in the present application solves the problem of poor sealing of the water pump 100 by setting a first annular platform 22 and a second annular platform 12 between the pump cover 2 and the valve seat 1, and making the second sealing portion 32 abut against the two, thereby significantly improving the sealing performance and overall operating stability of the water pump 100.

[0066] In one embodiment, see Figure 5The second sealing portion 32 is provided with a sealing rib 321 toward the first ring platform 22 , and the first ring platform 22 is provided with a first recessed groove 221 corresponding to the sealing rib 321 , and the sealing rib 321 is interference fit with the first recessed groove 221 .

[0067] In the technical solution, the second sealing portion 32 is provided with a sealing rib 321 toward the first ring platform 22, and the first ring platform 22 is provided with a first sink 221 corresponding to the sealing rib 321, and the sealing rib 321 is interference-fitted with the first sink 221. The design of the interference fit between the sealing rib 321 and the first sink 221 can enhance the sealing effect, prevent gas or liquid leakage, and thus improve the sealing performance of the water pump 100. This design helps to ensure that the water pump 100 has a good sealing effect during use, avoiding performance degradation due to poor sealing and potential damage to other structures in the water purification equipment.

[0068] Specifically, the sealing rib 321 can be realized in a variety of ways, for example, it can be made of rubber material to ensure that it has sufficient elasticity and wear resistance. At the same time, the size and shape of the first sink groove 221 need to match the sealing rib 321 to ensure the effect of interference fit. As a preferred embodiment, the sealing rib 321 can be set in a ring shape to ensure that the sealing pressure is evenly distributed on the entire contact surface, thereby further improving the sealing effect. In this embodiment, the shape of the sealing rib 321 is adapted to the shape of the second sealing portion 32. In addition, the height of the sealing rib 321 and the depth of the first sink groove 221 can be adjusted according to specific application requirements to ensure optimal sealing performance.

[0069] Therefore, the present application provides a sealing rib 321 on the second sealing portion 32 toward the first ring platform 22, and provides a first sink groove 221 corresponding to the sealing rib 321 on the first ring platform 22, so that the sealing rib 321 and the first sink groove 221 are interference-fitted, thereby effectively improving the sealing performance of the water pump 100. Compared with the prior art, the design of the present application can better prevent gas or liquid leakage, improve the overall performance of the water pump 100, and ensure the reliable operation of the water pump 100 in the water purification equipment.

[0070] In one embodiment, see Figure 3 A second groove 121 is disposed on the second ring platform 12 , and the second sealing portion 32 is at least partially disposed in the second groove 121 .

[0071] This technical solution mainly solves the problem of sealing performance. By providing the second sink groove 121 on the second ring platform 12, the second sealing portion 32 is at least partially embedded in the second sink groove 121, thereby enhancing the sealing effect. Specifically, the second sealing portion 32 is partially provided in the second sink groove 121, which can effectively prevent the leakage of liquid or gas, improve the sealing performance of the water pump 100, and further improve the overall performance and reliability of the water pump 100.

[0072] The second groove 121 on the second ring stage 12 can be realized in a variety of ways. For example, the second groove 121 can be formed on the second ring stage 12 by precision machining to ensure that its size and shape match the second sealing portion 32. The second sealing portion 32 can be made of a highly elastic material to ensure that it can be well embedded in the second groove 121 to form a reliable seal.

[0073] Through this design, the present application provides an improved sealing structure, which can effectively solve the problem of poor sealing performance in the prior art. Compared with the prior art, the technical solution of the present application significantly improves the sealing effect and reduces the risk of liquid or gas leakage by providing a second sink 121 on the second ring platform 12 and making the second sealing portion 32 at least partially disposed in the second sink 121, thereby improving the performance and reliability of the water pump 100.

[0074] Further, in one embodiment, see Figure 3 and Figure 6 The first ring platform 22 is provided with a plurality of first mounting holes 222 , and the second ring platform 12 is provided with a plurality of second mounting holes 122 . The plurality of first mounting holes 222 are respectively screwed to the plurality of second mounting holes 122 by screws.

[0075] Specifically, in the present application, a plurality of mounting holes are respectively provided on the first ring platform 22 and the second ring platform 12 of the water pump 100, and these mounting holes are screwed together by screws to ensure a more stable and tight connection between the pump cover 2 and the valve seat 1. This design not only simplifies the installation process, but also effectively improves the sealing performance of the water pump 100 to prevent gas or liquid leakage.

[0076] Furthermore, the second sealing portion 32 includes a plurality of arc segments 322 and a plurality of avoidance segments 323, and the opposite ends of any arc segment 322 are respectively connected to two avoidance segments 323, and the plurality of avoidance segments 323 are respectively used to avoid the plurality of first mounting holes 222. With this design, the second sealing portion 32 can provide a better sealing effect without affecting the position of the mounting hole, thereby ensuring the stability and reliability of the water pump 100 during operation.

[0077] It can be seen that the present application effectively solves the problem of poor sealing performance of the water pump 100 by setting mounting holes on the first ring platform 22 and the second ring platform 12 and screwing them together, combined with the design of the arc segment 322 and the avoidance segment 323 of the second sealing portion 32, thereby improving the overall performance and service life of the water pump 100.

[0078] In one embodiment, see Figure 4 and Figure 5 The second sealing portion 32 includes a plurality of arc segments 322 and a plurality of avoidance segments 323 , and the opposite ends of any arc segment 322 are respectively connected to two avoidance segments 323 , and the plurality of avoidance segments 323 are respectively used to avoid the plurality of first mounting holes 222 .

[0079] It should be noted that, in the present application, by providing a plurality of arc segments 322 and a plurality of avoidance segments 323, the second sealing portion 32 can avoid the first mounting hole 222 during installation, thereby ensuring the integrity and sealing effect of the sealing component. Specifically, the arc segment 322 is used to provide a sealing function, while the avoidance segment 323 is used to avoid the first mounting hole 222 during the installation process. This design can not only improve the sealing performance, but also simplify the installation process and reduce installation errors.

[0080] In practical applications, the arc segment 322 can be made of different materials and structures to adapt to different working environments and requirements. For example, the arc segment 322 can be made of a highly elastic material to improve the sealing performance; the avoidance segment 323 can be made of a wear-resistant material to extend the service life. As a preferred embodiment, the arc segment 322 and the avoidance segment 323 can be integrally formed by a mold to ensure the accuracy of their size and shape.

[0081] Compared with the prior art, the present application provides a plurality of arc segments 322 and a plurality of avoidance segments 323, so that the second sealing portion 32 can avoid the first installation hole 222 during installation, thereby ensuring the integrity and sealing effect of the sealing component. As a result, not only the sealing performance of the water pump 100 is improved, but also the installation process is simplified, installation errors are reduced, and work efficiency is improved.

[0082] In one embodiment, please continue to refer to Figure 4 and Figure 5 A water inlet chamber 4a is formed on the outer side of the first partition tube 11 and the second partition tube 21, and a water outlet chamber 4b is formed on the outer side of the first partition tube 11 and the second partition tube 21. A water inlet port 34 is formed between the first sealing portion 31 and the second sealing portion 32, and the water inlet port 34 is located in the water inlet chamber 4a. A water outlet port 35 is formed on the inner side of the first sealing portion 31, and the water outlet port 35 is located in the water outlet chamber 4b.

[0083] The technical solution of the present application is intended to solve the problem of insufficient sealing of the water pump 100. By forming a water inlet cavity 4a and a water outlet cavity 4b on the outside of the first partition 11 and the second partition 21, respectively, and forming a water inlet port 34 between the first sealing portion 31 and the second sealing portion 32, so that the water inlet port 34 is located in the water inlet cavity 4a, and forming a water outlet port 35 on the inside of the first sealing portion 31, so that the water outlet port 35 is located in the water outlet cavity 4b. In this way, the leakage of gas or liquid can be effectively prevented, and the sealing and performance of the water pump 100 can be improved.

[0084] Specifically, the outer sides of the first partition 11 and the second partition 21 form a water inlet chamber 4a and a water outlet chamber 4b, respectively. By forming a water inlet port 34 between the first sealing portion 31 and the second sealing portion 32, the water inlet port 34 is located in the water inlet chamber 4a, and the inner side of the first sealing portion 31 forms a water outlet port 35, so that the water outlet port 35 is located in the water outlet chamber 4b. This design can ensure the independence of the water inlet and outlet paths, avoid mutual interference, and further improve the sealing effect and working efficiency of the water pump 100. As a preferred embodiment, the first sealing portion 31 and the second sealing portion 32 can use high-performance sealing materials to further improve the sealing effect.

[0085] The technical solution of the present application effectively solves the problem of insufficient sealing of the water pump 100 in the prior art by optimizing the sealing structure of the water pump 100, improves the performance of the water pump 100, ensures the stable operation of the water purification equipment, and avoids damage to other structures of the equipment due to gas or liquid leakage.

[0086] In one embodiment, see Figure 3 A plurality of water inlet valves 13 and water discharge valves 14 are arranged on the valve seat 1 , and a plurality of the connecting ribs 33 separate the water inlet port 34 into a plurality of water outlets 341 , and the plurality of water outlets 341 correspond to the plurality of water inlet valves 13 one by one.

[0087] In the present application, the multiple water inlet valves 13 and the water discharge valves 14 are arranged on the valve seat 1, and the water inlet port 34 is divided into multiple water outlets 341 by multiple connecting ribs 33, so that each water outlet 341 corresponds to a water inlet valve 13. This design can effectively control the inlet and outlet of water flow, ensure that the water pump 100 can accurately adjust the water flow during operation, thereby improving the working efficiency and stability of the water pump 100.

[0088] In a specific implementation, the water inlet valve 13 and the drain valve 14 can be in various forms, such as a ball valve, a butterfly valve or other suitable valve types. The connecting rib 33 can be integrally formed, or connected to the valve seat 1 by welding, screwing, etc. The separation design of the water inlet port 34 can be adjusted according to actual needs to meet the requirements of different flow rates and pressures.

[0089] Thus, by arranging a plurality of water inlet valves 13 and drain valves 14 on the valve seat 1, and dividing the water inlet port 34 into a plurality of water ports 341 through the connecting ribs 33, the present application can effectively solve the sealing problem of the water pump 100 when adjusting the flow rate, avoid gas or liquid leakage, improve the performance of the water pump 100, and reduce the impact on other structures in the water purification equipment. Compared with the prior art, the technical solution of the present application has significant advantages in terms of sealing and flow control, and can better meet the use requirements of the water purification equipment.

[0090] In one embodiment, see Figure 6 and Figure 8 The pump cover 2 is provided with a limiting column 23 toward the drain valve 14. The drain valve 14 includes a fixing portion 141 and a valve plate 142 connected to the outside of the fixing portion 141. The limiting column 23 abuts against the fixing portion 141 to limit the relative position of the fixing portion 141 in the axial direction of the water pump 100.

[0091] It is understandable that the purpose of this technical solution is to improve the sealing performance of the water pump 100, thereby preventing gas or liquid leakage. By arranging the limit column 23 on the pump cover 2 so that it abuts against the fixing portion 141 of the drain valve 14, the relative position of the fixing portion 141 in the axial direction of the water pump 100 can be effectively limited, thereby ensuring the stability and sealing of the drain valve 14 during operation.

[0092] The limiting column 23 can be made of a variety of materials, such as metal, plastic, etc., and the specific selection can be determined according to the use environment and requirements of the water pump 100. The shape and size of the limiting column 23 can also be designed according to actual needs to ensure that it can safely abut against the fixing portion 141. As a preferred embodiment, the limiting column 23 can be set to a cylindrical or square column shape, and can be fixed on the pump cover 2 by means of threaded connection, snap connection, etc.

[0093] Through the above technical solution, the present application can effectively solve the problem of poor sealing performance of the water pump 100 in the prior art. The setting of the limit column 23 not only improves the stability of the drain valve 14, but also further enhances the overall sealing performance of the water pump 100, avoiding gas or liquid leakage, thereby improving the working efficiency and reliability of the water pump 100.

[0094] In one embodiment, see Figure 8 and Fig.10 A mounting groove 15 is provided in the middle of the valve seat 1 , and the drain valve 14 is installed in the mounting groove 15 .

[0095] It should be noted that a circular installation groove 15 is provided at the center of the valve seat 1 to install the drain valve 14 in the installation groove 15 and ensure that at least the valve plate 142 and the bottom of the installation groove 15 are completely fitted.

[0096] By installing the drain valve 14 in the installation groove 15 through the above technical solution, the stability of the drain valve 14 can be effectively improved, and the position displacement of the drain valve 14 caused by vibration or water flow impact can be avoided. In addition, the sealing performance is enhanced and the risk of water leakage is reduced.

[0097] In one embodiment, please continue to refer to Figure 8 and Fig.10 A limiting groove 151 is defined in the installation groove 15 , and the drain valve 14 further includes a limiting portion 143 , which is connected to the fixing portion 141 , and is disposed in the limiting groove 151 .

[0098] The above-mentioned embodiments have significantly improved the installation stability of the drain valve 14, but slight shaking or rotation may still occur in some cases, especially in an environment of high-pressure water flow impact. Therefore, further, a limiting groove 151 is opened in the installation groove 15, and a limiting portion 143 is correspondingly provided on the drain valve 14, which is limited in the limiting groove 151 by the limiting portion 143, thereby further improving the installation stability of the drain valve 14.

[0099] Through the above technical solution, the movement of the drain valve 14 at any angle in the axial and radial directions is effectively prevented, thereby enhancing the rigidity and reliability of the overall structure.

[0100] In one embodiment, see Fig.10 The limiting groove 151 is configured as a sink groove.

[0101] It should be noted that the limiting groove 151 is set as a sink groove. When the limiting column 23 abuts against the fixing portion 141, the limiting portion 143 can abut against the bottom of the limiting groove 151, thereby further improving the limiting effect of the limiting column 23 on the drain valve 14.

[0102] In one embodiment, see Figure 8 and Fig. 9 The limiting portion 143 and the fixing portion 141 are respectively located on two opposite sides of the valve plate 142 , and the limiting portion 143 and the fixing portion 141 correspond to each other in the axial direction of the water pump 100 .

[0103] Furthermore, the limiting portion 143 and the fixing portion 141 are respectively arranged on opposite sides of the valve plate 142, so that the valve plate 142 can fit with the bottom of the installation groove 15, and the fixing portion 141 and the limiting portion 143 correspond to each other in the axial direction of the water pump 100, thereby improving the installation effect of the water pump 100.

[0104] In one embodiment, see Figures 11 to 14 The water pump 100 further comprises a mounting seat 5 and a diaphragm 6, wherein the diaphragm 6 is mounted on the mounting seat 5, the diaphragm 6 comprises a diaphragm 61 and a plurality of cup capsules 62 connected to the diaphragm 61, and the cup capsules 62 have openings 621;

[0105] The diaphragm 61 is provided with convex ribs 611 protruding toward the valve seat 1 , and the convex ribs 611 are respectively arranged around the peripheries of the plurality of openings 621 .

[0106] The water pump 100 in the present application effectively solves the problem of poor sealing effect of the traditional diaphragm 6 pump by arranging multiple cup capsules 62 on the diaphragm 61 and arranging convex ribs 611 around the opening 621 of the cup capsules 62. The convex ribs 611 ensure the sealing between the various pressure chambers and prevent the occurrence of internal leakage, thereby improving the working efficiency and flow stability of the water pump 100. Compared with the prior art, the design of the present application significantly enhances the sealing performance of the diaphragm 6 pump and solves the problem of fluid reflux.

[0107] Specifically, the rib 611 can be continuously arranged in a ring shape around the periphery of the opening 621, or can be arranged in a spaced manner as a plurality of connected protrusions. The material of the rib 611 can be the same as the material of the diaphragm 6, usually a rubber material, to ensure sufficient elasticity and sealing performance. The height and width of the rib 611 can be designed according to actual needs to ensure that sufficient sealing pressure can be provided when the valve seat 1 abuts against the diaphragm 6. In addition, the shape of the rib 611 can also be optimized according to the specific application, for example, it can be designed into a trapezoidal, semicircular or other shapes to meet different sealing requirements.

[0108] By providing a plurality of connected ribs 611 on the sealing portion, the water pump 100 of the present application can effectively improve the sealing effect between the diaphragm 6 and the valve seat 1, reduce the occurrence of internal leakage, and thus improve the working efficiency and flow stability of the water pump 100. Compared with the prior art, the solution of the present application achieves a significant improvement in sealing performance through simple structural improvements, and has a high practical value.

[0109] Furthermore, the present application also proposes that the openings 621 are arranged at intervals along the circumference of the diaphragm 61 .

[0110] The technical problem of this technical solution is that by arranging the openings 621 at intervals along the circumference of the diaphragm 61, the sealing performance of the diaphragm 61 can be effectively improved, the leakage of the internal fluid can be reduced, and the working efficiency and flow stability of the water pump 100 can be improved.

[0111] In this technical solution, the openings 621 on the diaphragm 61 are not randomly distributed, but arranged at certain circumferential intervals. This arrangement can ensure that the diaphragm 61 area around each opening 621 can be evenly stressed, thereby maintaining a good sealing effect during operation. In addition, this arrangement can also avoid deformation of the diaphragm 61 caused by excessive concentration of the openings 621, thereby further improving the working efficiency and flow stability of the water pump 100.

[0112] Specifically, the openings 621 can be arranged in an equidistant manner along the circumference of the diaphragm 61, so that the distance between each opening 621 can be equal, so that the diaphragm 61 is evenly stressed during operation, and deformation and leakage caused by excessive local stress can be avoided. As a preferred embodiment, the spacing of the openings 621 can be adjusted according to the specific working requirements of the water pump 100 to achieve the best sealing effect and working efficiency.

[0113] In one embodiment, see Fig.13 An opening 613 is formed at the center of the diaphragm 61 , and the rib 611 surrounds the outer side of the opening 613 .

[0114] In the specific implementation process, the center of the diaphragm 61 can be provided with an opening 613 by means of mechanical processing or mold forming, and the sealing part can be arranged around the outside of the opening 613 by means of a protrusion made of rubber material. The sealing part can be integrally formed, or can be mounted on the diaphragm 61 by bonding or other fixing methods. Furthermore, the shape and size of the sealing part can be adjusted according to actual needs to ensure the best sealing effect.

[0115] It can be seen that the present application effectively solves the internal leakage problem caused by poor sealing effect in the prior art by opening the opening 613 at the center of the diaphragm 61 and setting a sealing part on the outside of the opening 613, thereby improving the working efficiency and flow stability of the water pump 100. Compared with the prior art, the technical solution of the present application is simple in structure, easy to implement, and has high practical value.

[0116] In one embodiment, see Fig.11 The mounting seat 5 is provided with a plurality of third mounting holes 51 , and the plurality of third mounting holes 51 are respectively fixed to the plurality of second mounting holes 122 by screws, and the diaphragm 61 is provided with a plurality of avoidance openings 614 corresponding to the plurality of first mounting holes 222 .

[0117] In the prior art, water purification equipment often uses a diaphragm 6 pump to increase pressure and control flow. However, due to the general sealing effect between multiple pressure chambers in the diaphragm 6 pump, internal leakage often occurs, causing part of the fluid to flow back, thereby reducing the working efficiency and flow stability of the water pump 100. The present application provides a better sealing effect, reduces internal leakage, and improves the working efficiency and flow stability of the water pump 100 by opening multiple mounting holes on the valve seat 1 and the mounting seat 5, respectively, and fixing them together with screws.

[0118] The technical solution of the present application mainly includes opening a plurality of third mounting holes 51 on the valve seat 1, opening a plurality of second mounting holes 122 on the mounting seat 5, and fixing the plurality of third mounting holes 51 to the plurality of second mounting holes 122 respectively by screws. This design helps to improve the connection strength between the valve seat 1 and the mounting seat 5, thereby enhancing the stability and sealing performance of the overall structure.

[0119] Specifically, the connection between the valve seat 1 and the mounting seat 5 is fixed by screws, so that the diaphragm 6 pump can better resist pressure changes during operation and reduce the chance of internal leakage. As a result, the working efficiency of the water pump 100 is improved and the flow stability is also significantly improved. As a preferred embodiment, the material and specifications of the screws can be selected according to actual needs to ensure its reliability and durability in different working environments.

[0120] The diaphragm 61 of the present application is provided with a plurality of avoidance openings 614, which correspond to a plurality of third mounting holes 51. With this design, the diaphragm 61 can avoid the third mounting holes 51 during installation, thereby ensuring that the diaphragm 61 can be correctly installed and closely matched with other components.

[0121] The avoidance opening 614 can be provided in a variety of ways, for example, the avoidance opening 614 can be directly punched or cut on the diaphragm 61, or the position of the avoidance opening 614 can be reserved when the diaphragm 61 is formed. The shape and size of these avoidance openings 614 can be designed according to actual needs to ensure that the diaphragm 61 can smoothly avoid the third mounting hole 51.

[0122] By providing the avoidance opening 614, the present application can effectively prevent the diaphragm 61 from being damaged or deformed during the installation process, thereby improving the installation efficiency and reliability of the water pump 100. Compared with the prior art, the design of the present application can better ensure the sealing effect between the diaphragm 61 and other components, reduce internal leakage, and improve the working efficiency and flow stability of the water pump 100.
