[0002] A water pump is a machine that transports or pressurizes liquids. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing the liquid's energy. It is mainly used to transport liquids, including water or oil.
[0003] For example, an automotive electronic water pump with authorization announcement number "CN222010348U" solves the problem that existing automotive electronic water pumps rely on the vehicle's power supply. Therefore, in the event of a power failure or battery disconnection, the above-mentioned pump is connected to a suitable power source through a circuit tube to ensure normal operation. The sensor is installed in the pump body to monitor the pump's operating status in real time, such as temperature and pressure parameters. Considering that the base of existing automotive electronic water pumps is directly fixed to the vehicle by threads, and that the pump's water extraction position is subject to friction between the water flow pulsation and the housing, resulting in high operating noise and a poor user experience.

Detailed Implementation
[0019] The present invention will be further described below with reference to the accompanying drawings:
[0020] Example 1: Please refer to Figure 1-6In this embodiment, a high-efficiency noise-reducing automotive electronic water pump includes a pump body 1 and a connecting sleeve 2. The pump body 1 consists of a motor, impeller, and temperature sensor, which is existing technology. Further details are omitted here. The outer wall of the pump body 1 is fixedly connected to the connecting sleeve 2, and the outer wall of the connecting sleeve 2 is fixedly connected to an electronic box 3. The electronic box 3 contains a display screen and a power cord, enabling the display and monitoring of power supply and temperature data for the pump body 1, thus meeting the usage requirements of the electronic water pump. The inner wall of the connecting sleeve 2 is fixedly connected to a rubber sealing ring 4, and a fixing mechanism 5 is connected to the outer wall of the connecting sleeve 2.
[0021] The fixing mechanism 5 includes a first fixing seat 501, which is fitted and pressed against the outer wall of the housing 703 by its inner side. The inner side of the second fixing seat 503 is pressed against the outer wall of the connecting sleeve 2. External bolts pass through the first fixing seat 501 and the second fixing seat 503 to perform threaded fixing installation with the external vehicle. The first fixing seat 501 is threadedly connected to the connecting sleeve 2 by bolts. The lower end of the first fixing seat 501 is pressed against the rubber pad 502, and the side end of the first fixing seat 501 is pressed against the second fixing seat 503.
[0022] The surface of the first fixed base 501 is machined with a connecting hole 6. The outer wall of the connecting sleeve 2 is connected to a noise reduction mechanism 7. A rubber and plastic sound-absorbing cotton 702 is added between the inner shell 701 and the outer shell 703 to reduce the noise of water flow pulsation in the inner shell 701. The noise reduction mechanism 7 includes an inner shell 701, which is fixedly connected to the connecting sleeve 2 by bolts. The outer wall of the inner shell 701 is in contact with the sound-absorbing cotton 702. The sound-absorbing cotton 702 is made of rubber and plastic and has an uneven surface to achieve the noise reduction effect. The outer wall of the sound-absorbing cotton 702 is in contact with the outer shell 703. The edge of the outer shell 703 is fixedly connected to the inner shell 701. The inner wall of the inner shell 701 is fixedly connected to the water inlet pipe 704 and the drain pipe 705.
[0023] The first fixed seat 501 and the second fixed seat 503 have rubber pads 502 of the same size that fit between the vehicle connections. The lower end of the water pump body 1 forms a shock absorption and noise reduction function. A rubber and plastic sound-absorbing cotton 702 is added between the inner shell 701 and the outer shell 703. When the water pump body 1 inside the inner shell 701 draws external liquid through the water inlet pipe 704, it can reduce the water flow pulsation noise in the inner shell 701, reduce the noise generated during operation, and improve the user experience.
[0024] The outer walls of the water inlet pipe 704 and the drain pipe 705 are bonded to the butyl rubber layer 8, and the surface of the electronic box 3 is machined with a wire outlet hole 9.
[0025] Working principle:
[0026] External bolts pass through the connecting sleeve 2, inner shell 701, and outer shell 703, sealing the inner shell 701 and connecting sleeve 2 with a rubber sealing ring 4. Simultaneously, other bolts pass through the first fixing seat 501, second fixing seat 503, connecting sleeve 2, inner shell 701, and outer shell 703, causing the inner side of the first fixing seat 501 to abut against the outer wall of the outer shell 703, and the inner side of the second fixing seat 503 to abut against the outer wall of the connecting sleeve 2. Furthermore, external bolts pass through the first fixing seat 501 and second fixing seat 503 to thread them onto the external vehicle. The first fixing seat 501 and second fixing seat 503 have the same size. Small rubber pads 502 are attached to the vehicle's connection points, so that when the water pump body 1 is working, the lower ends of the first fixed seat 501 and the second fixed seat 503 form a shock absorption and noise reduction effect. A rubber and plastic sound-absorbing cotton 702 is added between the inner shell 701 and the outer shell 703, so that when the water pump body 1 inside the inner shell 701 draws external liquid through the water inlet pipe 704, the noise of water flow pulsation in the inner shell 701 can be reduced. In addition, the butyl rubber layer 8 on the surface of the water inlet pipe 704 and the drain pipe 705 can absorb the vibration noise generated by water in the water inlet pipe 704 and the drain pipe 705, achieving overall efficient noise reduction.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
