Description

Technical Field

[0001] This utility model relates to the field of diaphragm pump technology, and specifically to a high-efficiency heat dissipation diaphragm pump. Background Technology

[0002] Existing diaphragm pumps have a closed cavity formed between the diaphragm seat, support frame, and fixed base. A transmission mechanism, including a swing arm and eccentric wheel, is installed within this cavity. A motor is mounted on the bottom side of the fixed base, with its drive shaft extending upwards into the cavity and connecting to the transmission mechanism. During operation, this type of diaphragm pump generates a significant amount of heat from the motor. This heat is transferred into the cavity and cannot escape quickly and efficiently. Furthermore, the heat can easily transfer back to the motor, causing rapid temperature rise and severely impacting the lifespan of the transmission mechanism and motor. While some diaphragm pumps incorporate a fan mechanism for cooling the motor, this increases costs, complicates the structure, hinders maintenance, and is neither economical nor practical.

[0028] See Figure 1-8 As shown in the figure, as an embodiment of the present invention, a high-efficiency heat dissipation diaphragm pump is provided. The diaphragm pump is a miniature high-pressure diaphragm water pump, which includes an upper cover 1, a valve seat 2, a diaphragm seat 3, a fixing assembly, and a drive mechanism assembled in sequence. The drive mechanism is a motor 7. A diaphragm 4 is provided on the diaphragm seat 3. The valve seat 2 is installed on the diaphragm seat 3. A valve plate 9 is provided in both the valve seat 2 and the upper cover 1. A sealing plate 10 is provided between the valve seat 2 and the upper cover 1. The upper cover 1 is provided with a feed hole 11 and a discharge hole 12. A receiving cavity 13 is formed between the diaphragm seat 3 and the fixing assembly. A transmission mechanism is installed in the receiving cavity 13. The drive mechanism is driven by the transmission mechanism. A heat dissipation channel 8 is provided in the fixing assembly. 3. The heat dissipation channel 8 connects to the outside, allowing the air inside the housing 13 to exchange heat with the outside air. The outside air can enter the housing 13 to achieve cooling, and the heat in the housing 13 can be discharged to the outside through the heat dissipation channel 8, thereby achieving efficient ventilation and heat dissipation of the diaphragm pump. This reduces the operating temperature of the various components of the diaphragm pump, extends the service life of the transmission mechanism, motor 7 and other components of the diaphragm pump, and enables the pressure of the diaphragm pump to be increased to more than 4 kg, making it suitable for high-pressure operation and providing stronger power. Moreover, the structure is simple, does not require the addition of a fan blade mechanism or other heat dissipation mechanism, is easy to manufacture and implement, easy to maintain, and has a low cost, making it more economical and practical.

[0029] In this embodiment, the fixing component includes a fixing base 5 and a support frame 6. The top side of the fixing base 5 is provided with a receiving groove 51, and the support frame 6 is fixedly installed in the receiving groove 51. The heat dissipation channel 8 includes a first heat dissipation channel 81 and a second heat dissipation channel 82. The first heat dissipation channel 81 is disposed in the support frame 6, and the second heat dissipation channel 82 is disposed between the bottom side of the support frame 6 and the receiving groove 51 of the fixing base 5. The receiving cavity 13 is connected to the outside through the first heat dissipation channel 81 and the second heat dissipation channel 82 in sequence. This structure is reasonably laid out, and the ventilation and heat dissipation effect is more balanced and orderly.

[0030] In this embodiment, the second heat dissipation channel 82 extends to the left and right. Specifically, the bottom side of the support frame 6 is provided with a downward-facing ventilation channel 62. The ventilation channel 62 and the groove surface of the receiving groove 51 of the fixed seat 5 cooperate to form the second heat dissipation channel 82. The bottom left and right sides of the fixed seat 5 are respectively provided with ventilation openings 52 that communicate with the second heat dissipation channel 82. The second heat dissipation channel 82 communicates with the external air through the ventilation openings 52.

[0031] In this embodiment, the ventilation channel 62 includes a central channel 621 located in the middle of the bottom side of the support frame 6 and end channel 622 symmetrically arranged on the left and right sides of the central channel 621. Two first heat dissipation channels 81 are symmetrically arranged on the left and right sides, respectively, and are vertically connected to the left and right sides of the support frame 6. The two first heat dissipation channels 81 are connected to the end channel 622. The first heat dissipation channels 81 and the second heat dissipation channels 82 are symmetrically arranged on the left and right sides, and the receiving cavity 13 and the first heat dissipation channels 81 form an inverted U-shaped ventilation channel. The second heat dissipation channel 82 is a straight ventilation channel connected below the inverted U-shaped ventilation channel, making the airflow path and direction inside the diaphragm pump more diverse (e.g., ...). Figure 2 The arrows in the diagram indicate one of the flow paths, which makes the ventilation channel structure inside the diaphragm pump longer and the airflow smoother, resulting in more sufficient heat exchange and more uniform and stable heat dissipation, further improving the heat dissipation efficiency of the diaphragm pump.

The drive mechanism is connected to the eccentric wheel 15 in a transmission connection. The swing frame 14 is rotatably mounted on the top of the eccentric wheel 15 through the second bearing 17.

[0033] In this embodiment, the output shaft of the motor 7 is inserted into the receiving cavity 13 and the support limiting groove 61, and the output shaft of the motor 7 is connected to the eccentric wheel 15 for transmission.

[0034] In this embodiment, a heat dissipation hole 71 is provided on the housing surface of the motor 7 near the fixing component, which further improves the heat dissipation effect of the motor 7.
