[0032] As mentioned in the background, the water pump is protected by a casing with ventilation holes on the side. However, existing water pump casings lack a human-machine interface (HMI) and circuit board, preventing users from obtaining real-time information about the pump's operating status and effectively controlling it. To address this issue, the researchers in this application propose a water pump protection device. One of its design objectives is to enable users to obtain motor operating information and effectively control the motor by incorporating a control panel and mainboard.

[0033] like Figure 1 As shown, Figure 1This is a schematic diagram of a water pump protection device according to one embodiment of this application. The water pump protection device includes: a housing 100, a mating part 200, a control panel 300, and a control main board 400. The housing 100 protects the motor; the mating part 200 mounts the control panel 300 and the control main board 400; the control panel 300 displays motor operating information and enables user interaction. The control panel 300 can be a display screen capable of presenting real-time motor status information and providing interactive functions; the control main board 400 enables electrical connection between the control panel 300 and the motor, and the control main board 400 can be a printed circuit board assembly (PCBA). In this embodiment, an objective of the present invention is to provide a control panel 300 and a control main board 400 in the water pump protection device, enabling the user to obtain real-time motor operating information and effectively operate the motor.

[0034] For details, please refer to Figure 1 As shown, the housing 100 is provided with a mating port 110, wherein the mating port 110 is distributed on two adjacent sides of the housing 100, and the housing 100 is used to protect the motor inside the water pump; the mating part 200 closes the mating port 110; the control panel 300 is provided on the mating part 200, and the control panel 300 is used to realize user interaction; the control motherboard 400 is provided on the mating part 200, and the control motherboard 400 is electrically connected to the control panel 300 and the motor respectively.

[0035] In this embodiment, the water pump protection device has a mating port 110 on the housing 100, allowing the control main board 400 in the mating part 200 to enter the inner cavity of the housing 100 and electrically connect to the motor through the mating port 110. The mating part 200 is used to seal the mating port 110 to reduce the risk of rainwater or other substances entering the interior of the housing 100. Since the control main board 400 is electrically connected to both the motor and the control panel 300, the user can obtain motor information through the control panel 300 located on the mating part 200, enabling effective control of the motor's operating information and operating mode. The mating ports 110 are distributed on two adjacent sides of the housing 100, providing two mounting surfaces for the installation of the mating part 200, making the installation process more direct and avoiding complex adjustments. Furthermore, the distribution of the mating ports 110 increases maintenance space, making maintenance and operation more convenient.

[0036] In one embodiment, see Figure 1 As shown, the mating openings 110 are distributed on the upper side of the housing 100 and the side adjacent to the upper side, and the mating part 200 has a bent structure; and / or, the control panel 300 is located on the upper side of the housing 100 corresponding to the mating part 200, and the control board 400 is located on the lower side of the mating part 200. The control board 400 can be fixed to the mating part 200 by means of threaded connection.

[0037] In this embodiment, by placing the mating opening 110 on the upper side of the housing 100 and the side adjacent to the upper side, the distribution of the mating opening 110 provides a clear installation positioning reference, allowing the bent mating part 200 to directly mate with the upper or lower side of the housing 100. This reduces the steps required for position adjustment during installation, simplifies the installation process, and improves installation efficiency. The control panel 300 is located on the upper side of the mating part 200. The position design of the control panel 300 allows users to obtain information and control the operation through an intuitive interface during pump operation. The control motherboard 400 is located on the lower side of the mating part 200, reducing the impact of external environmental factors on the control motherboard 400 and improving its protection.

[0038] In this embodiment, the outer shell 100 can be cuboid in shape, and the mating openings 110 are distributed on the upper side and the side including the width and height directions of the outer shell 100. The mating part 200 can be in the shape of the letter "L" to mate with the mating opening 110. Of course, the shape and structure of the outer shell 100 are not limited to this, and can also be a polygonal structure. At the same time, the shape of the mating part 200 can be adapted to the shape of the mating opening 110.

[0039] In one embodiment, see Figure 2 As shown, the edge of the mating opening 110 of the outer shell 100 is provided with a mounting part 120. The mating part 200 is connected to the mounting part 120. When the mating part 200 is installed on the mounting part 120, the horizontal distance between the edge of the mating part 200 and the edge of the mating opening 110 is less than or equal to 0.5 cm.

[0040] In this embodiment, a mounting portion 120 is provided at the edge of the mating opening 110 of the housing 100, for example, at the lower edge of the mating opening 110. The mounting portion 120 is mechanically connected to the mating portion 200, and the connection method can include threaded connection and snap-fit ​​connection. The horizontal distance between the edge of the mating portion 200 and the edge of the mating opening 110 on the same side is limited to less than or equal to 0.5 cm. This spacing design improves the sealing performance between the housing 100 and the mating portion 200 and reduces the risk of rainwater and dust entering the interior of the housing 100. The limited spacing ensures sealing performance while providing operating space for disassembly operations. For example, when using a snap-fit ​​connection, the snap-fit ​​can be set in the mating part 200 and the slot can be set in the mounting part 120. By engaging the snap-fit ​​and the slot, the mating part 200 is fixed in the mounting part 120. Since there is a gap between the mating part 200 and the mounting part 120, the mating part 200 can be easily disassembled by applying a force to the mating part 200 in the gap space.

[0041] In one embodiment, see Figure 1 and Figure 2 As shown, the water pump protection device also includes a protective cover 500, the opening of which faces the mating part 200. The control main board 400 is disposed in the inner cavity of the protective cover 500. A through hole 510 is provided on the side of the protective cover 500, which is used to allow the connection end of the control main board 400 to extend through.

[0042] In this embodiment, by providing a protective cover 500 in the water pump protection device, with the opening of the protective cover 500 facing the mating part 200, the control main board 400 can be disposed within the inner cavity of the protective cover 500, thereby achieving isolation and protection for the control main board 400 and further reducing the impact of the external environment on the control main board 400. A through hole 510 is provided on the side of the protective cover 500, allowing the connection end of the control main board 400 to pass through, thereby enabling electrical connection between the control main board 400 and the control panel 300 or the motor.

[0043] In one embodiment, see Figure 1 and Figure 2 As shown, a sealing groove is provided on the side of the mating part 200 facing the protective cover 500, and a sealing element 210 is provided in the sealing groove.

[0044] In this embodiment, by providing a sealing groove on the side of the mating part 200 facing the protective cover 500, and installing a sealing member 210 in the sealing groove, the sealing member 210 can effectively seal the gap between the mating part 200 and the protective cover 500, preventing external environmental factors such as rainwater and dust from entering the inner cavity of the protective cover 500, thereby protecting the control motherboard 400 from external factors. The sealing member 210 can be a sealing ring, such as an O-ring.

[0045] In one embodiment, see Figure 2 As shown, the connection end of the control motherboard 400 is equipped with a waterproof sleeve 410.

[0046] In this embodiment, by providing a waterproof sleeve 410 at the connection end of the control motherboard 400, the waterproof sleeve 410 can achieve sealing protection of the connection end, effectively preventing external environmental factors such as rainwater and dust from entering the connection end area, and ensuring that the control motherboard 400 maintains stable operation.

[0047] In one embodiment, see Figure 2 As shown, a mounting groove 220 is provided on the upper side of the mating part 200, and the mounting groove 220 is used to limit the position of the control panel 300.

[0048] In this embodiment, by providing a mounting groove 220 on the upper side of the mating part 200, the mounting groove 220 fixes the position of the control panel 300, thereby achieving stable installation of the control panel 300 and preventing the control panel 300 from shifting during external vibration or operation. Furthermore, sealant can be filled between the control panel 300 and the mounting groove 220 to further stabilize the position of the control panel 300 within the mounting groove 220.

[0049] In one embodiment, the surface of the control motherboard 400 is provided with a waterproof coating.

[0050] In this embodiment, by applying a waterproof coating to the surface of the control motherboard 400, the waterproof coating can prevent external environmental factors such as rainwater and dust from corroding the control motherboard 400, thereby ensuring the stable operation of the control motherboard 400 in humid environments or harsh weather conditions. The waterproof coating can be an ultraviolet-cured coating. After curing in the control motherboard 400, the waterproof coating can form a stable protective film, further enhancing the protective effect of the control motherboard 400 and improving the stability and reliability of the control motherboard 400 during long-term use.

[0051] In one embodiment, see Figure 2 As shown, heat dissipation holes 130 are provided on the side of the outer casing 100.

[0052] In this embodiment, by providing heat dissipation holes 130 on the side of the housing 100, the heat dissipation holes 130 can effectively promote air circulation inside the housing 100, thereby dissipating the heat generated by components such as motors during operation in a timely manner, and avoiding water pump failure or performance degradation due to excessive temperature.

[0053] This application also proposes a water pump, which includes the above-mentioned water pump protection device and a motor, wherein the motor is disposed in the inner cavity of the water pump protection device.

[0054] In this embodiment, the water pump includes a water pump protection device and a motor. A control main board 400 is installed in the mating part 200 of the protection device, and the control main board 400 is electrically connected to both the motor and the control panel 300. This allows the user to obtain motor information through the control panel 300 on the mating part 200, enabling effective control of the motor's operating information and operating mode. This effectively solves the problems of existing solutions where the water pump lacks access to motor operating information and cannot effectively operate the motor's operating status. Furthermore, the mating port 110 of the water pump protection device provides two mounting surfaces for the mating part 200, making the installation process of the mating part 200 more direct and avoiding complex adjustments. In addition, the distribution of the mating ports 110 increases maintenance space, making maintenance and operation more convenient.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
