Description

Technical Field

[0001] The utility model relates to the field of pumps, in particular to a swimming pool pump. Background Art

[0002] A swimming pool pump is a commonly used pump at present. A swimming pool pump is disclosed in the patent publication document CN213088262U. The pump with this structure drives the impeller to rotate through the motor. When the impeller rotates, the whole pump conveys water. The pump with this structure relies on the docking boss (the serial number of the attached drawing reference in the document is 54) for water diversion. Since the structure of the docking boss is roughly cylindrical, and the cylinder does not have a pressurizing effect when guiding water, there is a certain probability of backflow phenomenon, so its water diversion effect is relatively poor. Summary of the Utility Model

[0003] Aiming at the above problems, the utility model provides a swimming pool pump, which adopts a water guide device including a horn tube. When conveying water, the water flows from the wide end of the horn tube to the narrow end. During the water conveyance process, the water can be pressurized, avoiding water backflow, with a better water diversion effect, and relatively high water conveyance performance can be achieved with relatively low energy consumption.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A swimming pool pump includes a motor, a connecting seat and a pump body. The pump body is arranged at one end of the connecting seat, the motor is arranged at the other end of the connecting seat. An impeller is arranged on the shaft of the motor. The impeller is located inside the pump body. An inlet and an outlet are formed on the pump body. It further includes a water guide device. An inlet cavity and an outlet cavity are formed inside the pump body. The inlet is connected to the inlet cavity, the outlet is connected to the outlet cavity. The water guide device includes a bottom ring and a horn tube. The bottom ring is matched with the connecting seat, and the bottom ring is not in contact with the connecting seat. The narrow end of the horn tube is matched with the bottom ring, and the wide end of the horn tube is connected to the inlet cavity. The water guide device is located inside the outlet cavity, and the impeller is located between the connecting seat and the bottom ring.

[0006] The working process of this kind of swimming pool pump is as follows. First, the motor runs, and the running of the motor drives the impeller to rotate. Water enters the inlet cavity from the inlet of the pump body, then enters the horn tube of the water guide device after entering the inlet cavity, then passes through the bottom ring and enters the outlet cavity, and finally leaves the pump body from the outlet. The role of the rotation of the impeller is to make water continuously flow in from the inlet and flow out from the outlet.

[0007] In this type of pool pump, due to the use of a horn-shaped cylinder for water diversion, and under the action of the impeller, water flows from the wide end of the horn-shaped cylinder to the narrow end. During this process, the water pressure of the discharged water can be increased. However, a cylindrical tube does not have the ability to increase the water pressure as described above. Therefore, after the water is diverted through the horn-shaped cylinder, the water can continuously flow from the water inlet cavity into the water outlet cavity without flowing back from the water outlet cavity to the water inlet cavity. The diversion effect is better, and relatively high water conveyance performance can be achieved with relatively low energy consumption.

[0008] In summary, in this type of pool pump, a water diverter including a horn-shaped cylinder is adopted. When conveying water, the water flows from the wide end of the horn-shaped cylinder to the narrow end. During the water conveyance process, the water can be pressurized, preventing water backflow. The diversion effect is better, and relatively high water conveyance performance can be achieved with relatively low energy consumption.

[0009] Optionally, the water diverter further includes a plurality of diversion arc plates. The diversion arc plates are arranged on the bottom ring. The diversion arc plates and the horn-shaped cylinder are located on both sides of the bottom ring respectively, and the impeller is located between the diversion arc plates.

[0010] The function of the diversion arc plates is to divert water. When the water leaves the horn-shaped cylinder, it flows out through the gap between the diversion arc plates and enters the water outlet cavity.

[0011] Optionally, it further includes a filter screen cylinder, and the filter screen cylinder is arranged in the water inlet cavity.

[0012] The function of the filter screen cylinder is to filter. When the water enters the water inlet cavity from the water inlet, it is first filtered by the filter screen cylinder, then enters the horn-shaped cylinder after being filtered by the filter screen cylinder, and then enters the water outlet cavity through the diversion arc plates on the bottom ring, and finally leaves from the water outlet. The filter screen cylinder can filter debris in the water and prevent the impeller from being blocked during rotation.

[0013] Optionally, it further includes an end cover, and the end cover is arranged on the pump body.

[0014] Specifically, the end cover is detachably installed on the pump body. The function of the end cover is to facilitate the replacement of the filter screen cylinder. When the filter screen cylinder needs to be replaced, the end cover can be directly disassembled, and then the water inlet cavity is in an open state, so that the filter screen cylinder in the water inlet cavity can be taken out. After replacing the new filter screen cylinder, reinstalling the end cover can seal the water inlet cavity again.

[0015] Optionally, it further includes a sealing assembly, and the sealing assembly is arranged between the shaft of the motor and the connecting seat.

[0016] The function of the sealing assembly is to seal the gap between the shaft of the motor and the connecting seat. Specifically, the sealing assembly includes but is not limited to sealing rings and sealing bearings.

[0017] The beneficial effects of the present utility model are as follows: A flow guide device including a horn-shaped cylinder is adopted. When water is conveyed, water flows from the wide-mouth end to the narrow-mouth end of the horn-shaped cylinder. During the water conveyance process, water can be pressurized, reverse water flow is avoided, the flow guiding effect is better, and relatively high water conveyance performance can be achieved with relatively low energy consumption.

Detailed Embodiments

[0024] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the detailed embodiments of the present utility model will be described in detail below with reference to the drawings.

[0025] Many specific details are set forth in the following description in order to provide a thorough understanding of the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0026] As shown in the attached Figure 1 ~attached Figure 4As shown in the figure, a pool pump includes a motor 1, a connecting seat 2, and a pump body 3. The pump body 3 is disposed at one end of the connecting seat 2, and the motor 1 is disposed at the other end of the connecting seat 2. An impeller 6 is provided on the shaft of the motor 1, and the impeller 6 is located inside the pump body 3. The pump body 3 is provided with a water inlet 31 and a water outlet 32. It further includes a flow guide device. An inlet chamber 301 and an outlet chamber 302 are provided inside the pump body 3. The water inlet 31 is connected to the inlet chamber 301, and the water outlet 32 is connected to the outlet chamber 302. The flow guide device includes a bottom ring 42 and a bellows 41. The bottom ring 42 is fitted with the connecting seat 2, and the bottom ring 42 is not in contact with the connecting seat 2. The narrow end of the bellows 41 is fitted with the bottom ring 42, and the wide end of the bellows 41 is connected to the inlet chamber 301. The flow guide device is located inside the outlet chamber 302, and the impeller 6 is located between the connecting seat 2 and the bottom ring 42.

[0027] The working process of this pool pump is as follows. First, the motor 1 operates, and the operation of the motor 1 drives the impeller 6 to rotate. Water enters the inlet chamber 301 from the water inlet 31 of the pump body 3. After entering the inlet chamber 301, it then enters the bellows 41 of the flow guide device. After entering the bellows 41, it passes through the bottom ring 42 and then enters the outlet chamber 302. Finally, it leaves the pump body 3 from the water outlet 32. The function of the rotation of the impeller 6 is to continuously make water flow in from the water inlet 31 and flow out from the water outlet 32. The water flow direction during operation can be seen from the arrow directions in the attached Figure 2 figure.

[0028] In this pool pump, due to the use of the bellows 41 for flow guiding, and under the action of the impeller 6, water flows from the wide end to the narrow end of the bellows 41. In this process, the water pressure of the outlet can be increased. A cylinder does not have the ability to increase the water pressure as mentioned above. Therefore, after the water is guided by the bellows 41, the water can continuously flow from the inlet chamber 301 into the outlet chamber 302 and will not flow back from the outlet chamber 302 to the inlet chamber 301. The flow guiding effect is better, and relatively high water conveyance performance can be achieved with relatively low energy consumption.

[0029] In summary, in this pool pump, a flow guide device including the bellows 41 is adopted. When conveying water, water flows from the wide end to the narrow end of the bellows 41. The water can be pressurized during the water conveyance process, avoiding water backflow. The flow guiding effect is better, and relatively high water conveyance performance can be achieved with relatively low energy consumption.

[0030] As shown in the attached Figure 1 ~attached Figure 4 figure, the flow guide device further includes a plurality of flow guiding arc plates 43. The flow guiding arc plates 43 are disposed on the bottom ring 42. The flow guiding arc plates 43 and the bellows 41 are respectively located on both sides of the bottom ring 42, and the impeller 6 is located between the flow guiding arc plates 43.

[0031] The function of the diversion arc plate 43 is to divert water. After the water leaves the horn-shaped cylinder 41, it flows out through the gaps between the diversion arc plates 43 and enters the water outlet cavity 302.

[0032] As shown in the attached Figure 1 ~attached Figure 4 figure, it also includes a filter screen cylinder, which is arranged in the water inlet cavity 301.

[0033] The function of the filter screen cylinder is to filter. When the water enters the water inlet cavity 301 from the water inlet 31, it is first filtered by the filter screen cylinder, then enters the horn-shaped cylinder 41 after being filtered by the filter screen cylinder, and then enters the water outlet cavity 302 through the diversion arc plates 43 on the bottom ring 42, and finally leaves from the water outlet 32. The filter screen cylinder can filter out impurities in the water and avoid blockage of the impeller 6 during rotation.

[0034] As shown in the attached Figure 1 ~attached Figure 4 figure, it also includes an end cover 5, which is arranged on the pump body 3.

[0035] Specifically, the end cover 5 is detachably installed on the pump body 3. The function of the end cover 5 is to facilitate the replacement of the filter screen cylinder. When the filter screen cylinder needs to be replaced, the end cover 5 can be directly disassembled, and then the water inlet cavity 301 is in an open state, and the filter screen cylinder in the water inlet cavity 301 can be taken out. After replacing the new filter screen cylinder, reinstalling the end cover 5 can re-seal the water inlet cavity 301.

[0036] As shown in the attached Figure 1 ~attached Figure 4 figure, it also includes a sealing assembly 7, which is arranged between the shaft of the motor 1 and the connecting seat 2.

[0037] The function of the sealing assembly 7 is to seal the gap between the shaft of the motor 1 and the connecting seat 2. Specifically, the sealing assembly 7 includes but is not limited to sealing rings and sealing bearings.

[0038] Specifically, in this embodiment, the motor is an asynchronous motor, and the pool pump disclosed in this embodiment meets the US DOE energy consumption standard after actual measurement.
