Description

Technical Field

[0001] This utility model relates to the technical field of water pumps, and in particular to a water pump structure that reduces vibration and noise. Background Technology

[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, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals.

[0003] Existing water pump mechanisms, such as the integrated motor water pump disclosed in utility model patent application number 202421501287.1, mainly include a pump body, a gearbox, a motor, and a pump shaft. The pump body, gearbox, and motor are connected in sequence. An impeller assembly is provided in the pump body, and the impeller assembly is located near the water inlet. The gearbox, pump body, and motor are arranged on the same axis. The motor is connected to the pump shaft. In use, when the water inlet is immersed in water, the motor is turned on, and the motor, as the power source, starts to work. It transmits power to the pump shaft, causing the pump shaft to start rotating. As the pump shaft rotates, the impeller assembly closely connected to it also rotates at high speed.

[0004] However, most existing water pumps are quite noisy, and the mechanical vibration of the pump body generates noise, causing noise pollution to the surrounding environment. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a water pump structure that reduces vibration noise by embedding a vibration isolation pad in the housing and setting vibration isolation points between the housing and the pump housing. This effectively increases the transmission of vibration between the housing and the pump housing, while the setting of vibration isolation points also isolates the vibration noise generated by the collision between the pump housing and the housing.

[0006] This utility model discloses a water pump structure for reducing vibration and noise, including a housing; it also includes a power mechanism, a pump housing, and a vibration isolation mechanism. The power mechanism is mounted on the housing and rotates to generate suction. The pump housing is mounted on the housing to guide the water flow. The vibration isolation mechanism is mounted on the housing and reduces the vibration between the housing and the pump housing. The power mechanism is installed inside the housing, the vibration isolation mechanism is installed on the housing, and then the pump housing is installed on the housing, with a small gap between the housing and the pump housing. The power mechanism rotates to pump water, and the vibration noise is reduced by setting the vibration isolation mechanism.

[0007] Preferably, the power mechanism includes a stator and an impeller assembly. The stator is installed inside the housing, and the impeller assembly is installed on the stator. When energized, the stator drives the impeller assembly to rotate, and the impeller assembly rotates to pump water.

[0008] Preferably, the vibration isolation mechanism includes vibration isolation pads and multiple sets of vibration isolation points. The vibration isolation pads are installed inside the housing, and the vibration isolation pads gradually decrease in size along the flow channel of the housing. A vibration isolation point is arranged every 30°. The vibration isolation pads are embedded inside the housing and protrude 0.4mm above the housing plane. The gap between the housing plane and the pump housing plane is 0.2mm. Therefore, after the housing and pump housing are assembled, the vibration isolation pads produce an elastic deformation of 0.2mm. This elasticity can absorb and buffer external force impacts.

[0009] Preferably, the isolation point surface is provided with multiple sets of isolation bosses arranged in the circumferential direction; by setting the isolation bosses, the stiffness of the isolation point can be improved, thereby better absorbing buffering and impact.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the power mechanism is installed inside the housing, the vibration isolation mechanism is installed on the housing, and then the pump housing is installed on the housing, with a small gap between the housing and the pump housing. The power mechanism rotates to pump water, and the vibration noise is reduced by setting the vibration isolation mechanism. Attached Figure Description

[0017] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0018] Example 1

[0019] This utility model discloses a water pump structure for reducing vibration and noise, including a housing 01; it also includes a power mechanism 02, a pump housing 03, and a vibration isolation mechanism 04. The power mechanism 02 is mounted on the housing 01 and rotates to generate suction. The pump housing 03 is mounted on the housing 01 to guide the water flow. The vibration isolation mechanism 04 is mounted on the housing 01 and reduces vibration between the housing 01 and the pump housing 03. The power mechanism 02 includes a stator 21 and an impeller assembly 22. The stator 21 is mounted inside the housing 01, and the impeller assembly 22 is mounted on the stator 21. The vibration isolation mechanism 04 includes vibration isolation pads 41 and multiple sets of vibration isolation points 42. The vibration isolation pads 41 are mounted inside the housing 01, and... Furthermore, the vibration isolation pad 41 gradually decreases in size along the flow channel of the casing, and a vibration isolation point 42 is arranged every 30°. When it is working, firstly, the vibration isolation pad 41 is embedded inside the casing 01 and protrudes 0.4mm above the plane of the casing 01. The gap between the plane of the casing 01 and the plane of the pump casing 03 is 0.2mm. Therefore, after the casing 01 and the pump casing 03 are assembled, the vibration isolation pad 41 produces an elastic deformation of 0.2mm. This elasticity can absorb and buffer the impact of external forces. After being powered on, the stator 21 drives the impeller assembly 22 to rotate. The impeller assembly 22 rotates to pump water. The vibration isolation pad 41 and the vibration isolation point 42 reduce the vibration between the casing 01 and the pump casing 03, thereby reducing the operating noise of the water pump.

[0020] Example 2

[0021] like Figures 1 to 5 As shown, the water pump structure of this utility model for reducing vibration and noise, based on embodiment 1, further includes multiple sets of vibration isolation bosses 43 arranged circumferentially on the surface of the vibration isolation point 42. During operation, the vibration isolation pad 41 is first embedded inside the housing 01, protruding 0.4mm above the plane of the housing 01. The gap between the plane of the housing 01 and the plane of the pump housing 03 is 0.2mm. Therefore, after the housing 01 and the pump housing 03 are assembled, the vibration isolation pad 41 undergoes a 0.2mm elastic deformation. This elasticity can absorb and buffer external impacts. By setting the vibration isolation bosses 43, the stiffness of the vibration isolation point 42 can be improved, thereby better absorbing, buffering, and impacts. After power is applied, the stator 21 drives the impeller assembly 22 to rotate, and the impeller assembly 22 rotates to pump water. The vibration isolation pad 41 and the vibration isolation point 42 reduce the vibration between the housing 01 and the pump housing 03, thus reducing the operating noise of the water pump.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
