Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, and in particular to a heat dissipation structure for a waterproof gearbox for swimming pools. Background Technology

[0002] Gearboxes, as driving components, are widely used in various electrical appliances. Pool gearboxes, in particular, are the core power source for equipment such as water pumps, filtration systems, and pool cleaning robots. Their design must balance sealing, corrosion resistance, and long-term reliability. A typical gearbox generally consists of a housing, a motor, and a gear set. The motor and gear set are encapsulated inside the housing, with the motor shaft directly connected to the gear set to ensure efficient power output.

[0003] However, to adapt to the humid environment of swimming pools, gearboxes on the market generally adopt a fully sealed structure to isolate moisture, but this also prevents heat from being effectively dissipated inside the casing. The heat from motor operation and the frictional heat from gear transmission continuously accumulate, causing the internal temperature to rise steadily. Prolonged high temperatures will damage the motor's insulation performance and shorten its lifespan. Ultimately, the overall reliability of the gearbox decreases, the failure frequency increases significantly, and the maintenance costs of swimming pool equipment increase substantially.

[0004] Therefore, it is necessary to improve existing technologies. Utility Model Content

[0034] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0035] like Figures 1 to 11 As shown, this embodiment provides a heat dissipation structure for a waterproof pool gearbox, including a cleaning roller brush 1, a gearbox assembly 2, an output fan blade 3, and a metal base plate 4. The gearbox assembly 2 is disposed inside the cleaning roller brush 1 and forms a heat dissipation channel 5 between the two. The front end of the gearbox assembly 2 is a power output end 6, which is connected to the cleaning roller brush 1. The output fan blade 3 is connected to the power output end 6 of the gearbox assembly 2 and is located between the front end of the gearbox assembly 2 and the cleaning roller brush 1. The rear end of the gearbox assembly 2 is connected to the metal base plate 4, and the rear end of the gearbox assembly 2 and the cleaning roller brush 1 are connected by a roller brush connecting assembly 8.

[0036] A front heat dissipation hole 11 is provided on the front side of the cleaning roller brush 1, and a rear heat dissipation hole 813 is provided on the roller brush connecting assembly 8. The two sides of the heat dissipation channel 5 are respectively connected to the front heat dissipation hole 11 and the rear heat dissipation hole 813. Water flows through the rear heat dissipation hole 813 into the heat dissipation channel 5 to dissipate heat from the gearbox assembly 2, and finally flows out through the heat dissipation channel 5 and the front heat dissipation hole 11.

[0037] The heat dissipation channel 5 is connected to the front heat dissipation hole 11 and the rear heat dissipation hole 813 on both sides, creating a hollow design at both ends of the gearbox assembly 2. Therefore, when the gearbox assembly 2 is running, the cleaning roller brush 1 rotates synchronously with the power output end 6, and the output end fan blades 3 drive water to flow in from the bottom, simultaneously carrying away the heat generated inside the gearbox during operation, greatly extending the service life of the waterproof gearbox.

[0038] This invention proposes a heat dissipation structure for a waterproof gearbox for swimming pools. By using water flow to carry away the heat generated during the operation of the waterproof gearbox, the service life of the waterproof gearbox is extended and the daily maintenance costs for users are reduced.

[0039] Specifically, a limiting part 12 is provided in the middle of the front end of the cleaning roller brush 1, and the bottom of the limiting part 12 is provided with a mounting groove 13 that matches the output end fan blade 3. The mounting groove 13 adapts to the unique structure of the output end fan blade 3, thereby making the connection between the two stable and preventing the output end fan blade 3 from loosening when the gearbox assembly 2 is running. A limiting post 14 is provided on the other side of the limiting part 12, and a number of evenly distributed grooves 15 are provided between the limiting post 14 and the top of the cleaning roller brush 1. A number of front heat dissipation holes 11 are evenly distributed at the connection between the limiting post 14 and the limiting part 12. The setting of the grooves 15 makes it convenient for equipment manufacturers to develop more products that are compatible with this swimming pool waterproof gearbox as needed, and expand the application scenarios of this swimming pool waterproof gearbox.

[0040] Furthermore, the gearbox assembly 2 includes a housing 21, a motor 22, a gearbox 23, a positive wiring harness 24, and a negative wiring harness 25. The motor 22 is located inside the rear end of the housing 21, and the gearbox 23 is located inside the front end of the housing 21. The gearbox 23 and the motor 22 are connected by a first rotating shaft 27. The positive wiring harness 24 and the negative wiring harness 25 are connected to the rear end of the motor 22. A wire outlet hole 41 is provided on the metal base plate 4. One end of the positive wiring harness 24 and the negative wiring harness 25 is electrically connected to the motor 22, and the other end passes through the wire outlet hole 41 and is connected to a terminal. This arrangement makes the gearbox assembly 2 compact, and the motor 22 is directly connected to the gearbox 23, ensuring efficient power output.

[0041] Preferably, the gearbox 23 and the output fan blade 3 are connected via a second rotating shaft 28. The gearbox assembly 2 is provided with a rear positioning member 26, which is connected to the housing 21. The rear positioning member 26 ensures the overall stability of the gearbox assembly 2.

[0042] Furthermore, the output fan blade 3 includes a shaft hole 31, with a screw mounting groove 32 recessed at the top center of the shaft hole 31. Several evenly distributed fixing posts 33 are provided at the bottom of the screw mounting groove 32 and on the inner circumference of the shaft hole 31. This arrangement facilitates structural adaptation between the output fan blade 3 and the power output end 6, making the overall connection more stable.

[0043] Preferably, the output fan blade 3 further includes a connecting platform 34 and a blade positioning ring 35. The connecting platform 34 is located at the lower end of the shaft hole 31. A plurality of drainage holes 36 are evenly distributed at the connection between the connecting platform 34 and the shaft hole 31. A plurality of protrusions 37 with intermediate bends are evenly distributed between the drainage holes 36 and on the outer periphery of the shaft hole 31.

[0044] The connecting platform 34 is provided with a connecting slope 38 extending downwards. The blade positioning ring 35 is provided at the lower end of the connecting slope 38, and a number of blades 351 are evenly distributed on the blade positioning ring 35.

[0045] The design of the drain hole 36 and the blade 351 allows the water in the heat dissipation channel 5 to be discharged into the pool under the drive of the output fan blade 3.

[0046] Specifically, the second rotating shaft 28 has an internal thread at its top end and a connecting collar 7 on its outer periphery. The connecting collar 7 has several fixing grooves 71 on its outer periphery that fit the fixing post 33. The top end of the second rotating shaft 28 is detachably connected to a screw 29. A washer 20 is placed between the screw 29 and the second rotating shaft 28. The screw 29 passes through the screw mounting groove 32 and connects to the gearbox assembly 2. The connection between the screw 29 and the second rotating shaft 28 strengthens the connection between the gearbox assembly 2 and the output fan blade 3. The design of the connecting collar 7 and the addition of the washer 20 increase the contact surface between the second rotating shaft 28 and the output fan blade 3, allowing for better transmission of power from the second rotating shaft 28 to the output fan blade 3.

[0047] Furthermore, a bearing 9 is provided on the outer periphery of the rear positioning member 26, and the roller brush connecting assembly 8 is provided on the outer periphery of the bearing 9. The roller brush connecting assembly 8 includes a connecting ring 81 and a connecting washer 82. The connecting ring 81 has an inner groove 811 on its inner side and an outer groove 812 on its outer side. The inner groove 811 is connected to the outer periphery of the bearing 9, and the connecting washer 82 is embedded in the outer groove 812 and closely attached to the inner wall of the housing 21. This makes the connection between the gearbox assembly 2 and the housing 21 tight, and the connecting washer 82 further increases the friction between the two, making the connection more stable.

[0048] A plurality of rear heat dissipation holes 813 are evenly arranged on the connecting ring 81, between the inner slot 811 and the outer groove 812. Under the action of the output fan blade 3, the front end of the pool waterproof gearbox drains water into the pool when it is working. Under the action of the water flow, the water flows into the heat dissipation channel 5 through the rear heat dissipation holes 813, and also drives the water in the heat dissipation channel 5 to move towards the output fan blade 3, thereby carrying away the heat in the gearbox assembly 2.

[0049] It should be noted that the metal base plate 4 is connected to the rear positioning member 26, and a gap is left between the metal base plate 4 and the connecting ring 81. This allows for water inlet space at the bottom of the pool gearbox, making it easier for water to flow into the rear heat dissipation hole 813.

[0050] Furthermore, the cleaning roller brush 1 has several spiral patterns evenly distributed on its outer circumference. The roller brush 1 rotates as the output fan blade 3 moves. When the cleaning roller brush 1 is in operation, the spiral pattern design causes the flow of water around the cleaning roller brush 1 to change accordingly.

[0051] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
