Description

Technical Field

[0001] This utility model relates to a shock-absorbing component for a water pump in drinking water equipment, and in particular a shock-absorbing component for a water pump arranged in a vertical direction. Background Technology

[0002] Water pumps inside drinking water equipment such as instant hot water dispensers and coffee machines vibrate and generate noise during operation. This is especially true when the pump is positioned vertically or roughly vertically, as the close contact between the pump body and the equipment housing transfers the pump's vibrations to the housing, resulting in even greater noise. Common water pump vibration damping components typically include damping springs at the bottom of the pump to minimize vibration. For example, the spring buffer structure disclosed in Chinese utility model patent CN218246845U can absorb vibrations generated during pump operation, with springs at both the bottom and top of the pump. However, water pumps vibrate not only vertically but also horizontally and in other irregular ways. In practical applications, relying solely on springs for vibration damping is not very effective. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a water pump vibration damping component that can reduce multi-directional vibration, so as to overcome the defect of poor vibration damping effect in the prior art.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A water pump vibration damping assembly is provided, suitable for water pumps installed in a vertical or substantially vertical direction, including a bracket, an upper vibration damper and a lower vibration damper. The upper and lower vibration dampers are detachably connected to the bracket. The upper part of the water pump is connected to the upper part of the bracket through the upper vibration damper, and the lower vibration damper is located between the lower part of the water pump and the base of the bracket.

[0006] Furthermore, the lower shock absorber includes a shock absorber seat and a lower connecting part that are connected to each other, and the lower connecting part is detachably connected to the bracket.

[0007] Furthermore, there is a shock-absorbing protrusion between the shock-absorbing seat and the base of the bracket.

[0008] Furthermore, the shock-absorbing seat has shock-absorbing wings on both sides, and the base has protruding edges on both sides. The shock-absorbing wings are located between the lower part of the water pump and the protruding edges.

[0009] Furthermore, the side of the shock-absorbing seat has a first shock-absorbing protrusion, and the two sides of the base have convex edges. The first shock-absorbing protrusion collides or is squeezed with the inner sidewall of the convex edge during vibration.

[0010] Furthermore, the bottom of the shock-absorbing seat has a second shock-absorbing protrusion, which collides or is squeezed with the upper surface of the base during vibration.

[0011] Furthermore, the shock absorber seat and the lower connecting part are connected by a corrugated part, which has anti-collision protrusions.

[0012] Furthermore, the upper shock absorber includes a shock absorber ring located on its upper part, the shock absorber ring being tightly fitted onto the outer wall of the water pump's outlet pipe.

[0013] Furthermore, the upper shock absorber includes an outer side located at its lower part, the inner shape of which matches the upper shape of the water pump.

[0014] Furthermore, the outer side has an inner side inside, and the inner side matches the shape of a portion of the upper part of the water pump.

[0015] Compared with the prior art, the advantages of this utility model are that shock-absorbing components are provided at both the top and bottom of the water pump. The shock-absorbing components with matching shapes are provided at the top of the conventional water pump, which not only ensures the stable connection between the shock-absorbing components and the water pump and the beverage equipment using the water pump, but also provides shock-absorbing protrusions at the bottom where the vibration intensity is relatively greater, which completely avoids direct contact between the water pump and the rigid support. Combined with the shock-absorbing springs in the prior art, a better shock absorption effect can be achieved. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Reference Figure 1-5 This utility model's water pump vibration damping assembly is applicable to a water pump 100 installed in a vertical or approximately vertical direction. The inlet pipe 110 is located below the water pump body, and the outlet pipe 120 is located above the water pump body. The vibration damping assembly includes a bracket 200, an upper vibration damper 300, and a lower vibration damper 500. Both the upper vibration damper 300 and the lower vibration damper 500 are made of vibration damping material, such as rubber.

[0030] The bracket 200 supports the water pump 100 and mounts the upper shock absorber 300 and the lower shock absorber 500. It includes an upper mounting position located at the top of the bracket 200 and a lower mounting position located at the bottom of the bracket 200. The upper mounting position is used to mount the upper shock absorber 300, and the lower mounting position is used to mount the lower shock absorber 500. The bracket 200 includes a base 220 and a support plate 210 extending vertically upward from one side of the base 220. In one embodiment, the upper mounting position includes a first hole 201 located at the top of the support plate 210, and the lower mounting position includes a second hole 202 located at the bottom of the support plate 210. The water pump 100 has a water pump bracket 130, with the water pump body mounted inside the water pump bracket 130. An inlet pipe 110 extends from below the water pump bracket 130, and an outlet pipe 120 extends from above the water pump bracket 130.

[0031] The upper shock absorber 300 includes a shock-absorbing ring 320 located at its upper part and an outer side 310 located at its lower part. The shock-absorbing ring 320 has a first through hole 301, allowing the water outlet pipe 120 to extend out of the shock-absorbing ring 320. The shock-absorbing ring 320 is tightly fitted onto the outer side wall of the water outlet pipe 120. In one embodiment, the outer side wall of the water outlet pipe 120 has an annular groove 121 that mates with the inner side of the shock-absorbing ring 320. Figure 1 , 2 As shown. The inner shape of the outer side 310 matches the shape of the upper part of the water pump bracket 130, so as to better wrap the upper part of the water pump 100 body for shock absorption. In one embodiment, as Figure 3B As shown, the outer side 310 has an inner side 311 inside, and the inner side 311 further matches the shape of the upper part of the water pump bracket 130 (e.g., a circular step or annular step) to achieve better shock absorption.

[0032] In one embodiment, the upper shock absorber 300 has an upper connecting portion 330, which is connected to the upper mounting position via an upper connecting assembly. In one embodiment, the upper connecting assembly includes an upper connecting protrusion 331 and an upper connecting hole 332 located on the upper connecting portion 330; the upper mounting position includes an upper positioning protrusion 230 and a first hole 201 located on the upper part of the support plate 210, the upper connecting portion 330 passes through the first hole 201, and the upper connecting hole 332 is sleeved on the upper positioning protrusion 230 to prevent the upper connecting portion 330 from coming out of the first hole 201 during vibration; the upper connecting protrusion 331 is engaged with the upper edge of the first hole 201 to further prevent the upper connecting portion 330 from coming out of the first hole 201 during vibration. In one embodiment, a first gap 302 is formed between the upper connecting portion 330 and the adjacent outer side 310, and the lower edge of the first hole 201 is engaged with the first gap 302 to form a wrapping state of the lower edge of the first hole 201. In other embodiments, there may be only an upper connecting protrusion 331, or only an upper positioning protrusion 230 and an upper connecting hole 332. Different numbers and positions of the above components may also be provided as needed to achieve a more stable connection.

In one embodiment, one end of the damping spring 600 abuts against the lower edge of the second through hole 501. In another embodiment, one end of the damping spring 600 abuts against the bottom of the water pump bracket 130. The other end of the damping spring 600 and the water inlet end of the water inlet pipe 110 extend out from the third through hole 203 of the base 220.

[0034] In one embodiment, the shock-absorbing seat 520 has shock-absorbing wings 521 on both sides, and the base 220 has protruding edges 221 on both sides. The shock-absorbing wings 521 are located between the lower part of the water pump bracket 130 and the protruding edges 221 to avoid or reduce vibration caused by direct or indirect contact between the water pump bracket 130 and the base 220. In one embodiment, the side of the shock-absorbing seat 520 has a first shock-absorbing protrusion 522. Two or more first shock-absorbing protrusions 522 are distributed along the extending direction of the shock-absorbing wings 521. During vibration, the first shock-absorbing protrusions 522 continuously or intermittently collide or squeeze with the inner wall of the protruding edges 221 to further reduce horizontal vibration caused by direct or indirect contact between the water pump bracket 130 and the base 220. In one embodiment, the bottom of the shock absorber 520 has a second shock-absorbing protrusion 523, and two or more second shock-absorbing protrusions 523 are distributed on the bottom surface of the shock absorber 520. The second shock-absorbing protrusions 523 continuously or intermittently collide or squeeze with the upper surface 204 of the base 220 to further reduce the vertical vibration caused by direct or indirect contact between the water pump bracket 130 and the base 220.
