Description

Technical Field

[0001] The present application relates to the technical field of water pump equipment, and in particular to a swimming pool pump. Background Art

[0002] A swimming pool circulating pump is an important component of a pool's water treatment system. It is responsible for pumping water out of the pool, filtering it, disinfecting it, and then returning it to the pool, ensuring the water is clean and safe.

[0003] In the related art, a filter part and an impeller part are provided on the pool pump body. A water inlet is provided on the filter part for external water to enter. A connecting hole is provided between the filter part and the impeller part. An opening is provided on the filter part. The filter basket is installed in the filter part through the opening. An end cover covering the opening is also installed on the filter part. The end cover is generally fixed to the housing of the filter part by screws. The pool pump body needs to regularly disassemble the end cover to remove the filter basket for cleaning, and then install it back into the filter part.

[0004] Regarding the above-mentioned related technologies, since the filter part and the impeller part are interconnected, a pressure difference is generated when the impeller part is working, resulting in the end cover being difficult to open due to the influence of the internal pressure of the filter part, and there is still room for improvement. Utility Model Content

[0005] In order to facilitate the detachment of the end cover from the pool pump body and reduce the damage to the pool pump body around the end cover, the present application provides a swimming pool pump.

[0006] This application provides a swimming pool pump, which adopts the following technical solution:

[0007] A swimming pool pump comprises a pool pump body, wherein the pool pump body is provided with an opening for taking out and placing a filter basket, an end cover for covering the opening is rotatably connected to the pool pump body, cams are rotatably connected to the opposite outer circumferential side walls of the pool pump body, an abutment is fixedly connected to the opposite outer circumferential side walls of the end cover, two cams are located below the abutment and abut against the abutment in a one-to-one correspondence, and a push rod extending outside the abutment is fixedly connected to the side of the cam away from the pool pump body.

[0008] By adopting the above technical solution, a cam is rotatably connected to the outer wall of the pool pump body. The staff rotates the push rod so that the end of the cam squeezes and pushes the abutment on the end cover to move, thereby applying force to the end cover away from the pool pump body, making it easier for the staff to open the end cover from the pool pump body, reducing the phenomenon of maintenance personnel using foreign objects to assist in prying the end cover, thereby damaging the pool pump body around the end cover, and improving the opening efficiency of the end cover.

[0009] Optionally, a handle is provided on the pool pump body, and both ends of the handle are fixedly connected to the ends of the two push rods in a one-to-one correspondence.

[0010] By adopting the above technical solution, since there are two push rods, the setting of the handle makes it convenient for maintenance personnel to push the two push rods at the same time when pushing the handle, thereby improving the rotation efficiency of the cam.

[0011] Optionally, a positioning block is fixedly connected to a side of the push rod close to the end cover, and a circumferential side wall of the positioning block is pressed against a side of the abutting portion away from the cam.

[0012] By adopting the above technical solution and setting the positioning block, when the handle and the push rod are vertically on the end cover, the positioning block is pressed against the abutment and cooperates with the cam to clamp the abutment, thereby locking the end cover. When there is no need to clean or replace the filter basket, the end cover can be fixed, thereby increasing the sealing between the end cover and the pool pump body.

[0013] Optionally, the side of the abutting portion away from the cam is arranged in an arc shape and forms an arc surface that slides with the positioning block, and the arc surface is inclined toward the side close to the cam.

[0014] By adopting the above technical solution, the arc surface is set at an angle. When the push rod rotates, the positioning block on the push rod can slide along the inclined arc surface, making it easier for the cam to pry up the entire abutment portion from the side of the abutment portion away from the arc surface.

[0015] Optionally, a groove for engaging with a portion of the positioning block is formed on a side of the abutting portion away from the cam.

[0016] By adopting the above technical solution and setting the groove, when the end cover is closed, the push rod is in a vertical state. At this time, part of the positioning block can be clamped in the groove, further tightening the abutment part on the end cover, thereby increasing the sealing of the end cover and the pool pump body when the end cover is closed.

[0017] Optionally, a gap is formed on a side of the abutting portion away from the cam to form a limiting elastic piece, and an end portion of the limiting elastic piece is tightly pressed against the outer circumferential side wall of the positioning block.

[0018] By adopting the above technical solution, the setting of the gap allows the limiting elastic piece to move slightly, which facilitates the positioning block to move along the arc surface into the groove and can prevent the positioning block from easily sliding off the arc surface.

[0019] Optionally, a side of the abutting portion close to the pushing rod is fixedly connected to a limiting plate, and a side of the limiting plate close to the arcuate surface is tightly pressed against the pushing rod.

[0020] By adopting the above technical solution, the setting of the limit plate can limit the rotation range of the push rod, reduce the excessive rotation range of the push rod, and cause the positioning block to detach from the side of the groove away from the arc surface, thereby improving the rotation accuracy of the push rod.

[0021] Optionally, a reinforcing rib is fixedly connected inside the abutting portion.

[0022] By adopting the above technical solution and setting the reinforcing ribs, the structural strength of the abutment portion can be further increased, and the damage caused by the friction of multiple rotations of the cam can be reduced.

[0023] Optionally, a connecting block covering the reinforcing rib is clamped on a side of the abutting portion away from the end cover.

[0024] By adopting the above technical solution, the setting of the connecting block can further cover the reinforcing ribs, thereby increasing the structural strength of the abutment portion, and at the same time can reduce the wear of the reinforcing ribs when the push rod rotates, thereby increasing the service life of the abutment portion.

[0025] Optionally, an indicator mark is provided on a side of the cam away from the pool pump body.

[0026] By adopting the above technical solution, the indicator can instruct the staff to rotate the push rod in the prompted direction, which is convenient for the staff to operate.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the cam rotates, the end of the cam squeezes and pushes the abutment on the end cover to move, exerting force on the end cover to move away from the pool pump body, making it easier for the end cover to separate from the pool pump body, reducing damage to the pool pump body around the end cover and improving the opening efficiency of the end cover;

[0029] 2. The positioning block is set. When the end cover is in the closed state, the positioning block is tightly against the abutment and cooperates with the cam to clamp the abutment, thereby locking the end cover and improving the sealing between the end cover and the pool pump body;

[0030] 3. The setting of the limit piece can limit the rotation range of the push rod, reducing the excessive rotation range of the push rod, which causes the positioning block to detach from the side of the groove away from the curved surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following is combined with Figure 1-6 This application is described in further detail.

[0039] A coordinate system XYZ is provided in the drawings of the embodiments of the present application, wherein the positive direction of the X-axis represents the left side, the negative direction of the X-axis represents the right side, the positive direction of the Y-axis represents the top, the negative direction of the Y-axis represents the bottom, the positive direction of the Z-axis represents the front side, and the negative direction of the Z-axis represents the back side.

[0040] The present application discloses a swimming pool pump. Figure 1 A swimming pool pump includes a pump body 1. The pump body 1 includes an integrally formed impeller portion 11 and a filter portion 2. The filter portion 2 has a water inlet 21, and the impeller portion 11 has a water outlet 12. The filter portion 2 and the impeller portion 11 are interconnected, allowing water in the swimming pool to enter the filter portion 2 through the water inlet 21 for cleaning and filtration, and then flow through the impeller portion 11 and out through the water outlet 12.

[0041] Combine Figure 2 and Figure 3, an opening 13 is provided at the upper end of the filter portion 2 so that the staff can take the filter basket out of the filter portion 2 through the opening 13 for cleaning. An end cover 22 for covering the opening 13 is rotatably connected to the filter portion 2, and the rotation point of the end cover 22 and the water inlet 21 are located on the same side. A cam 23 arranged in a fan shape is rotatably connected to the outer wall of the filter portion 2. There are two cams 23 and they are respectively located on the relative circumferential side walls of the filter portion 2 near one end of the opening 13. An abutment 221 is fixedly connected to the relative circumferential side walls of the end cover 22, and the two cams 23 are both located below the abutment 221. The two cams 23 abut on the lower side wall of the abutment 221 in a one-to-one correspondence, so that the abutment 221 can be pushed to move during the rotation of the cam 23.

[0042] Reference Figure 3 A push rod 231 extending beyond the abutment portion 221 is fixedly connected to the side of the cam 23 away from the filter portion 2, allowing maintenance personnel to push the push rod 231 to rotate the cam 23. A handle 3 is mounted on the pool pump body 1, with both ends of the handle 3 fixedly connected to the ends of two oppositely arranged push rods 231, allowing users to push both push rods 231 simultaneously.

[0043] Reference Figure 3 and Figure 4 A positioning block 232 is fixedly connected to the side of the push rod 231 near the end cap 22. The outer wall of the positioning block 232 near the cam 23 abuts against the top of the abutting portion 221, thereby cooperating with the cam 23 to clamp the end cap 22. A groove 2211 is formed on the side of the abutting portion 221 away from the cam 23. When the positioning block 232 cooperates with the cam 23 to clamp the end cap 22, a portion of the lower portion of the cam 23 is engaged in the groove 2211.

[0044] Reference Figure 4 and Figure 5 The side of the abutting portion 221 away from the cam 23 is provided with an arcuate surface 2212. The end of the arcuate surface 2212 away from the groove 2211 is inclined toward the cam 23, thereby facilitating the sliding of the positioning block 232 along the arcuate surface 2212 when the push rod 231 is rotated. The side of the abutting portion 221 away from the cam 23 is provided with two slits 2213. The slits 2213 are separated from the groove 2211 and the arcuate surface 2212. The two slits 2213 cooperate with the abutting portion 221 to form a limiting elastic piece 222. The end of the limiting elastic piece 222 is tightly pressed against the outer circumferential side wall of the positioning block 232 located in the groove 2211. Part of the arcuate surface 2212 is located on the limiting elastic piece 222, which preliminarily limits the positioning block 232 from being easily disengaged from the groove 2211.

[0045] Reference Figure 3When the end cover 22 is in a closed state, the push rod 231 and the handle 3 are vertically above the end cover 22. At this time, the upper rear portion of the cam 23 is tightly pressed against the lower outer wall of the abutting portion 221, and part of the positioning block 232 is engaged with the groove 2211. The positioning block 232 and the cam 23 cooperate to clamp the abutting portion 221 on the end cover 22, thereby increasing the stability of the end cover 22 covering the filter portion 2.

[0046] Reference Figure 4-6 The cam 23 is provided with an indicator mark 233 on the side away from the filter part 2. When the staff pushes the handle 3 toward the rear side of the cam 23 according to the indicator mark 233, the end cover 22 is in the unlocking process. At this time, the positioning block 232 slides along the arc surface 2212 toward the side of the water inlet 21 under the influence of the pushing rod 231. When the positioning block 232 disengages from the arc surface 2212, the cam 23 also rotates along the lower side of the abutment 221 under the influence of the pushing rod 231. The front end of the cam 23 is pressed against the side of the lower side wall of the abutment 221 away from the water inlet 21. The force applied by the cam 23 can push the abutment 221 toward the side away from the cam 23, thereby prying up the end cover 22.

[0047] Reference Figure 5 and Figure 6 The front end of the abutting portion 221 close to the impeller portion 11 is fixedly connected to a limiting plate 223, and the limiting plate 223 is located on the side of the abutting portion 221 close to the push rod 231. The rear side of the limiting plate 223 away from the impeller portion 11 abuts against the side of the push rod 231 close to the impeller portion 11, thereby limiting the rotation range of the push rod 231.

[0048] Reference Figure 5 and Figure 6 A reinforcing rib 224 is fixedly connected to the abutment portion 221, thereby increasing the overall structural strength of the abutment block. A connecting block 225 is clamped to the side of the abutment portion 221 away from the end cover 22. The connecting block 225 covers the reinforcing rib 224 in the abutment portion 221, thereby reducing the wear of the reinforcing rib 224 by the push rod 231.

[0049] The implementation principle of a swimming pool pump in an embodiment of the present application is as follows: when the pool pump needs to be cleaned after working for a period of time, the staff holds the handle 3 and pushes the handle 3 toward the side of the water inlet 21. At this time, the positioning block 232 slides along the arc surface 2212, and the cam 23 rotates along the lower side wall of the abutment block while pushing the abutment portion 221 to move. The end cover 22 is detached from the opening 13 of the filter part 2. At this time, the end cover 22 is flipped open, and the staff takes out the filter basket from the opening 13 for cleaning. After cleaning is completed and put back into the filter part 2, the handle 3 is pushed to rotate toward the front to restore the locked state of the end cover 22.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
