Description

Technical Field

[0001] The present application relates to the technical field of hot water pumps, and in particular to a circulating hot water pump with a silent mechanism. Background Art

[0002] A circulating hot water pump is a water pump used for hot water circulation inside buildings. It transports hot water from a water heater or boiler to each faucet, and returns cold water to the water heater or boiler for reheating after use, thereby realizing the recycling of hot water. It plays an important role in hot water circulation, voltage stabilization, energy saving, etc., and is widely used in industry, commerce, and residential life.

[0003] Patent No. CN 221236960 U discloses a circulating hot water pump with an attached silent mechanism. The arc-shaped pressure plate on the side wall of the slide can fit on the outer wall of the output shaft to support it, and the X-shaped shock-absorbing pad is squeezed between the pressure plate and the output shaft to stop the vibration, thereby better offsetting the vibration generated during the operation of the output shaft. The pressure plate is arranged in two upper and lower pieces corresponding to the slide, and the stretching plate passes through the sliding cavity opened between the upper and lower pressure plates. When the output shaft vibrates during operation, the outward thrust generated by the vibration of the output shaft will offset the extrusion force of the tension plate pulling the pressure plate inward, thereby making the output shaft more stable during operation and less likely to deviate, making it less likely to make noise when the water suction pump is running, and having a better silent effect, and making the water suction pump more efficient.

[0004] However, in use, there are the following defects:

[0005] Although anti-vibration pads are used to absorb and offset the vibration thrust of the water pump's output shaft, since the water pump and motor are fixedly installed on the base, they will vibrate when working, which will be transmitted to the base to generate additional noise, affecting the efficiency of noise reduction.

The soft pad on the surface of the splint and the side shock absorber at the back can absorb and unload the lateral vibration, reducing the noise generated by the vibration of the equipment itself, and the sound-absorbing cotton on the inside of the sound-absorbing frame can absorb the noise generated by the rotation inside the output shaft, thereby minimizing the noise generation; the slider can slide freely laterally on the inside of the slide groove, thereby driving the electric push rod and the splint to move laterally together, select the appropriate position for fitting, and the adjustment block can slide freely in the adjustment groove, and cooperate with the telescopic rod to adjust the position and height of the sound-absorbing frame, thereby adapting to the position and height of different output shafts.

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, they are further elaborated below in conjunction with specific implementation methods.

[0022] A circulating hot water pump with a silent mechanism, see Figures 1 to 2, including a base 1, a buffer plate 10, an adjusting block 18 and a fixing bolt 401, the top of the base 1 is fixedly connected to a plurality of bottom shock absorbers 9, the top of the bottom shock absorber 9 is fixedly connected to a buffer plate 10, the bottom buffer plate 10 and the bottom shock absorber 9 can absorb and unload vibrations in the vertical direction, and the left and right sides of the top of the buffer plate 10 are respectively fixedly connected to the pump body 13 and the motor 12, and an output shaft 14 is connected between the motor 12 and the pump body 13; the front and rear ends of the top of the base 1 are fixedly connected to the side plates 2, the soft pads 801 on the surface of the splint 8 and the side shock absorbers 7 at the back can absorb and unload lateral vibrations, reducing the noise generated by the vibration of the equipment itself, and a slide groove 3 is provided on the surface of the side plate 2 facing the center of the base 1, the inner side of the slide groove 3 is slidably connected to the slider 4, the outer side wall of the slider 4 is fixedly connected to the electric push rod 5, the other end of the electric push rod 5 is fixedly connected to the support plate 6, the support plate 6 The surface facing the central side of the base 1 is fixedly connected to the plywood 8 through the side shock absorber 7; an adjustment slot 17 is provided at the center of the top of the buffer plate 10, and an adjustment block 18 is connected to the inner side of the adjustment slot 17 for horizontal sliding. The top of the adjustment block 18 is fixedly connected to a telescopic rod 19, and the top of the telescopic rod 19 is fixedly connected to a sound-absorbing frame 15. The sound-absorbing frame 15 is fixedly connected to the outer surface of the output shaft 14, and the inner side of the sound-absorbing frame 15 is provided with sound-absorbing cotton 16. The sound-absorbing cotton 16 inside the sound-absorbing frame 15 can absorb the noise generated by rotation inside the output shaft 14, reducing the noise generation. The slider 4 can slide freely laterally on the inner side of the slide groove 3, thereby driving the electric push rod 5 and the plywood 8 to move laterally together, select a suitable position for fitting, and the adjusting block 18 can slide freely in the adjusting slot 17, and cooperate with the telescopic rod 19 to adjust the position and height of the sound-absorbing frame 15, thereby adapting to the position and height of different output shafts 14.

[0023] Specifically, such as Figure 2 As shown, the surface of the base 1 below the buffer plate 10 is fixedly connected to a limiting rod 11, and the top of the limiting rod 11 passes through the upper surface of the buffer plate 10. The limiting rod 11 can ensure that the buffer plate 10 can remain parallel to the surface of the base 1 when moving up and down to unload force, thereby ensuring the stability of the equipment.

[0024] It is worth noting that if Figure 1 As shown, the surface of the splint 8 facing the center side of the base 1 is fixedly connected with a soft pad 801. The soft pad 801 can make it easier for the splint 8 to fit the surface of the device, and can cooperate with the side shock absorber 7 at the back to perform shock-absorbing and buffering treatment. When the splint 8 fits the device, it does not need to be too tight. It only needs to squeeze the soft pad 801 to avoid clamping too tightly and affecting the up and down movement of the device.

[0025] It is worth noting that if Figure 1As shown, a secondary groove 301 is provided on the surface of the side plate 2 above the slide 3, the secondary groove 301 is connected to the slide 3, and the fixing bolt 401 passes horizontally through the secondary groove 301 and is threadedly connected to the slider 4.

The lower half of the sound-absorbing frame 15 is connected to the telescopic rod 19, and the upper half can be separated after the connecting bolts 151 are twisted off. The internal sound-absorbing cotton 16 can be filled so that it can fit the surface of the output shaft 14 of different thicknesses.

[0028] In actual use, after the device is started, the buffer plate 10 and the bottom shock absorber 9 at the bottom can absorb and unload the vibration in the vertical direction, and the splint 8 reaches both sides of the device and sticks to the surface of the device under the extension and contraction of the electric push rod 5. The soft pad 801 on the surface of the splint 8 and the side shock absorber 7 at the back can absorb and unload the lateral vibration, reducing the noise generated by the vibration of the device itself, and the sound-absorbing cotton 16 inside the sound-absorbing frame 15 can absorb the noise generated by the rotation inside the output shaft 14, thereby minimizing the noise. The noise is generated, and at the same time, through the slide 3, slider 4, adjustment slot 17, telescopic rod 19 and adjustment block 18, the number of positions of the splint 8 and the position of the sound-absorbing frame 15 can be customized. The slider 4 can slide freely laterally on the inner side of the slide 3, thereby driving the electric push rod 5 and the splint 8 to move laterally together, and select a suitable position for fitting, and the adjustment block 18 can slide freely in the adjustment slot 17, and cooperate with the telescopic rod 19 to adjust the position and height of the sound-absorbing frame 15, thereby adapting to the position and height of different output shafts 14, thereby improving the adaptability and practicality of the device.
