[0045] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0047] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] like Figure 1 As shown, a vibration reduction structure of a pump body in this embodiment includes a pump body 10, a first mounting frame 20, a second mounting frame 30 and a first vibration reduction member 40. The pump body 10 is connected to the first mounting frame 20. The first mounting frame 20 is connected to the second mounting frame 30 to connect the pump body 10 to the second mounting frame 30. The first vibration reduction member 40 is arranged between the first mounting frame 20 and the second mounting frame 30.

[0050] By adopting the technical solution of this embodiment, a first vibration damper 40 is arranged between the first mounting frame 20 and the second mounting frame 30. When the pump body 10 is working, the vibration of the pump body 10 will drive the first mounting frame 20 to vibrate. The first vibration damper 40 can absorb the vibration between the first mounting frame 20 and the second mounting frame 30, thereby eliminating the collision noise between the first mounting frame 20 and the second mounting frame 30 as much as possible, thereby reducing the working noise. Therefore, the technical solution of this embodiment solves the defects of the water purifier in the prior art, such as high working noise and poor user experience.

[0051] As Figure 1 and Figure 2 shown, in the technical solution of this embodiment, a receiving cavity 31 is provided on the second mounting bracket 30, and the first mounting bracket 20 is disposed in the receiving cavity 31. The first damping member 40 is disposed between the first mounting bracket 20 and the inner wall of the receiving cavity 31. Specifically, the pump body 10 is disposed in the receiving cavity 31 through the first mounting bracket 20, and the first damping member 40 is disposed between the first mounting bracket 20 and the inner wall of the receiving cavity 31. It can not only absorb the vibration generated by the second mounting bracket 30, but also prevent the collision that may occur between the first mounting bracket 20 and the side wall of the receiving cavity 31 when the pump body 10 is working, thereby indirectly reducing the noise generated by the whole machine driven by the pump body 10 during operation.

[0052] As Figures 1 to 5 shown, in the technical solution of this embodiment, the second mounting bracket 30 includes a mounting base 32 and a cover body 34. Among them, a receiving recess 33 is provided on the mounting base 32, and the first mounting bracket 20 is disposed in the receiving recess 33. The cover body 34 covers the receiving recess 33, and the space between the receiving recess 33 and the cover body 34 forms the receiving cavity 31. Among them, the first damping member 40 is disposed between the first mounting bracket 20 and the inner walls of the receiving recess 33 and the cover body 34. Specifically, from Figure 2 it can be seen that a side wall is provided on the side of the second mounting bracket 30, and the side wall encloses the above-mentioned receiving recess 33. During installation, one end of the first mounting bracket 20 extends into the receiving recess 33, and then the cover body 34 is covered on the receiving recess 33, and the first mounting bracket 20 is fixed between the receiving recess 33 and the cover body 34. Further, the side wall of the receiving recess 33 and the cover body 34 are fixed by a buckle and a bolt. When the pump body 10 is working, the first mounting bracket 20 may collide with the inner side wall of the receiving recess 33 and the inner side wall of the cover body 34. Therefore, the above-mentioned first mounting members are provided between the first mounting bracket 20 and the receiving recess 33, and between the first mounting bracket 20 and the cover body 34, that is, two first damping members 40 are provided in this embodiment. Of course, the first damping member 40 may also be provided only between the first mounting bracket 20 and the receiving recess 33, or only between the first mounting bracket 20 and the cover body 34.

[0053] As Figure 5 shown, in the technical solution of this embodiment, the first damping member 40 includes two first damping pads 41. One of the two first damping pads 41 is disposed between the first mounting bracket 20 and the bottom wall of the mounting base 32, and the other is disposed between the first mounting bracket 20 and the top wall of the cover body 34. Combining Figure 1 and Figure 5As can be seen, the pump body 10 is vertically installed in the receiving recess 33. Therefore, the two first vibration damping pads 41 are arranged on the first mounting bracket 20 on both sides perpendicular to the axial direction of the pump body 10. During specific installation, first, one first vibration damping pad 41 is arranged on one side of the first mounting bracket 20, then the first mounting bracket 20 is placed in the receiving recess 33, and the side of the first mounting bracket 20 and the bottom wall of the receiving recess 33 clamp the first vibration damping pad 41. Then, the other first vibration damping pad 41 is installed on the other side of the first mounting bracket 20, the cover body 34 is covered on the receiving recess 33, and the other side of the first mounting bracket 20 and the top wall of the cover body 34 clamp the first vibration damping pad 41. The cover body 34 is fixed to the receiving recess 33 by snap fasteners and screws, thus completing the assembly. The above structure enables the first mounting bracket 20 to contact the receiving recess 33 and the cover body 34 through the first vibration damping pad 41, so that the vibration generated by the first mounting bracket 20 is absorbed by the first vibration damping pad 41, greatly reducing the noise generated when the pump body 10 works.

[0054] As Figure 5 , Figure 7 and Figure 10 shown, in the technical solution of this embodiment, the first vibration damping pad 41 is sleeved outside the side of the first mounting bracket 20 along the width direction. Specifically, convex mounting protrusions are arranged on the two sides of the first mounting bracket 20, and the first vibration damping pad 41 is provided with recesses adapted to the mounting protrusions. The first vibration damping pad 41 is sleeved on the mounting protrusions of the first mounting bracket 20 through the recesses. The above structure facilitates positioning the first vibration damping pad 41 on the first mounting bracket 20, thus facilitating assembly. Preferably, an interference fit design is adopted between the first vibration damping pad 41 and the first mounting bracket 20.

[0055] As Figure 1 and Figure 2 shown, in the technical solution of this example, the vibration damping structure further includes a sound absorption structure 50 arranged between the first mounting bracket 20 and the inner wall of the receiving cavity 31. Specifically, the sound absorption structure 50 is used to absorb noise. Although the first vibration damping pad 41 is arranged between the first mounting bracket 20, the receiving recess 33 and the cover body 34, a small amount of noise will still be generated when the pump body 10 works. The sound absorption structure 50 is used to absorb the above-mentioned small amount of noise, thereby further reducing the working noise of the pump body 10.

[0056] As Figure 1 and Figure 2 shown, in the technical solution of this example, the sound absorption structure 50 includes sound-absorbing cotton, and the sound-absorbing cotton is clamped between the inner wall of the receiving recess 33 and the side of the first mounting bracket 20 along the length direction. Specifically, the sound absorption structure 50 is arranged on the side wall at the bottom of the receiving recess 33. Combining Figure 1It can be seen that the sound-absorbing cotton is located at the side position of the first mounting bracket 20 along the axial direction of the pump body 10, that is, when the first mounting bracket 20 is installed in the receiving recess 33, the sound-absorbing cotton is adjacent to the positions of the two first vibration damping pads 41. Further preferably, the sound-absorbing cotton is mostly composed of two-component cotton, centrifugal glass wool, etc.

[0057] As Figure 1 , Figure 5 and Figure 6 shown, the vibration damping structure further includes a connecting pipe 60 and a second vibration damping member 70. One end of the connecting pipe 60 is connected to the pump body 10, and the other end of the connecting pipe 60 passes through the inner wall of the receiving cavity 31. The second vibration damping member 70 is disposed between the connecting pipe 60 and the inner wall of the receiving cavity 31. Specifically, the connecting pipe 60 is used to connect the pump body 10 to an external structure. It should be noted that, as described above, since the receiving cavity 31 is formed by the receiving recess 33 and the cover body 34, the phrase "the other end of the connecting pipe 60 passes through the inner wall of the receiving cavity 31" means that the connecting pipe 60 passes through the side wall of the receiving recess 33 or the side wall of the cover body 34. Since the connecting pipe 60 will also vibrate when the pump body 10 is working, in order to further reduce the working noise, a second vibration damping member 70 is disposed between the connecting pipe 60 and the inner wall of the receiving cavity 31. The vibration of the connecting pipe 60 is absorbed by the second vibration damping member 70.

[0058] Preferably, the outer portion of the connecting pipe 60 located outside the installation cavity 21 is wrapped with a sponge sleeve.

[0059] As Figure 5 shown, in the technical solution of this embodiment, the cover body 34 is provided with a mounting hole, the connecting pipe 60 passes through the mounting hole, and the second vibration damping member 70 is disposed between the connecting pipe 60 and the mounting hole. Specifically, the connecting pipe 60 contacts the mounting hole through the second vibration damping member 70, and the second vibration damping member 70 can absorb the vibration of the connecting pipe 60, thereby further reducing the working noise. Of course, as described above, the mounting hole can also be provided on the side wall of the receiving recess 33.

[0060] As Figure 6 shown, in the technical solution of this embodiment, the second vibration damping member 70 includes a damping ring 71, an annular groove 72 is provided on the outer side wall of the damping ring 71, the hole wall of the mounting hole is clamped in the annular groove 72, and the connecting pipe 60 passes through the damping ring 71. Specifically, the above-mentioned annular groove 72 facilitates installation and positioning.

[0061] Preferably, in the technical solution of this embodiment, the second damping member 70 is in interference fit with the mounting hole and also in interference fit with the connecting pipe 60. Specifically, the above structure enables the connecting pipe 60 to be fixed more stably on the cover body 34, thereby reducing or even eliminating the shaking of the connecting pipe 60 and reducing the operating noise of the pump body 10. Through the above structural arrangement, the vibration transmitted from the connecting pipe 60 to other external devices can also be reduced. Of course, an interference fit installation method can also be set only between the second damping member 70 and the mounting hole, or only between the second damping member 70 and the connecting pipe 60.

[0062] As Figure 1 , Figures 7 to 12 shown, in the technical solution of this embodiment, the damping structure further includes a third damping member 80, and the third damping member 80 is arranged between the first mounting bracket 20 and the pump body 10. Since the pump body 10 is directly mounted on the first mounting bracket 20, when the pump body 10 operates, the vibration will first be transmitted to the first mounting bracket 20. By providing the third damping member 80, the vibration between the pump body 10 and the first mounting bracket 20 can be absorbed, that is, the generation of noise can be suppressed from the vibration source.

[0063] As Figure 7 , Figure 8 and Figure 10 shown, in the technical solution of this embodiment, the first mounting bracket 20 includes a mounting cavity 21, the inner wall of the mounting cavity 21 is adapted to the outer contour of the pump body 10, the pump body 10 is arranged in the mounting cavity 21, and the third damping member 80 is arranged between the pump body 10 and the inner wall of the mounting cavity 21. Specifically, the first mounting bracket 20 can be generally regarded as a cylindrical structure with two open ends, and the contour of the internal space of the cylindrical structure is adapted to the outer contour of the pump body 10, so that the pump body 10 can be inserted into the mounting cavity from the opening of the mounting cavity 21. The third damping member 80 arranged between the pump body 10 and the inner wall of the mounting cavity 21 can absorb the vibration of the pump body 10, thereby reducing the noise generated by the collision between the pump body 10 and the inner wall of the mounting cavity 21.

[0064] As Figures 8 to 11 shown, in the technical solution of this embodiment, the damping structure further includes a fastener 90, the fastener 90 is connected between the pump body 10 and the first mounting bracket 20, and the third damping member 80 is sleeved outside the fastener 90. Specifically, the above setting method facilitates the positioning of the third damping member 80.

[0065] As Figures 7 to 10 , and Figures 12 to 14As shown, in the technical solution of this embodiment, the pump body 10 includes an installation side 11. The third shock absorber 80 includes a second shock pad 81 disposed on the installation side 11. A first through hole 82 is provided on the second shock pad 81, and a second through hole 22 is provided on the inner wall of the installation cavity 21. The first through hole 82 and the second through hole 22 are correspondingly arranged, and the fastener 90 is inserted into the first through hole 82 and the second through hole 22. Specifically, the installation side 11 is fixed on the pump body 10 and is detachably arranged. Installation sides are provided on both sides of the pump body 10. Flat cavities adapted to the installation side 11 are provided on both sides of the installation cavity 21, and the second through hole 22 is provided on the bottom wall of the flat cavity. During installation, first insert the pump body 10 into the installation cavity 21, then align the first through hole 82 and the second through hole 22, and insert the fastener 90 into the first through hole 82 and the second through hole 22, so as to complete the fastening of the pump body 10 and the first mounting bracket 20.

[0066] Preferably, the fastener 90 in this example includes a fastening bolt 91 and a fastening nut 92. The fastening bolt 91 is inserted into the first through hole 82 and the second through hole 22, and the fastening nut 92 is arranged at the end of the fastening bolt 91 and is located at the bottom of the second mounting bracket 30.

[0067] As Figure 7 shown, in the technical solution of this embodiment, a limiting groove 23 is provided at the position corresponding to the second through hole 22 at the bottom of the first mounting bracket 20, and the fastening nut 92 is arranged in the limiting groove 23. Specifically, the limiting groove 23 is a slot with an opening facing outwards, and the opening of the limiting groove is directly below the second through hole 22. The fastening nut 92 is press-fitted in the limiting groove 23. The limiting groove 23 can limit the circumferential rotation of the fastening nut 92, and after the fastening nut 92 is arranged in the limiting groove 23, the hole of the fastening nut 92 is aligned with the second through hole 22. During installation, insert the fastening bolt 91 into the first through hole 82 and the second through hole 22, and rotate the fastening bolt 91 to achieve the assembly with the fastening nut. It should be noted that, as Figure 7 can be seen, the upper wall surface and the lower wall surface of the above-mentioned flat cavity are misaligned at the position corresponding to the second through hole 22, that is, there is no structure blocking above the second through hole 22, so as to facilitate the knob operation of the fastening bolt 91.

[0068] As Figure 8 and Figure 9As shown, in the technical solution of this embodiment, an opening groove 12 is provided on the installation side 11, a clamping groove 83 is provided on the outer side wall of the second shock pad 81, the second shock pad 81 is arranged in the opening groove 12, and the inner wall of the opening groove 12 is clamped in the clamping groove 83. Specifically, the above structure makes the installation of the second shock pad 81 simple: when installing the second shock pad 81, the second shock pad 81 can be inserted into the inner wall of the opening groove 12 through the opening, and the cooperation between the clamping groove 83 and the inner wall of the opening groove 12 can limit the up and down movement of the second shock pad 81.

[0069] Further, it should be noted that two opening grooves 12 are provided on each installation side 11. Since the two installation sides 11 of the pump body 10 have the same structure, only one side is taken as an example for description: the two opening grooves 12 are respectively located on the front and rear sides of the installation side 11, and particularly, the opening directions of the two opening grooves 12 are opposite. Each opening groove 12 is provided with a second shock pad 81, so as to ensure the smooth force at the front and rear ends of the pump body 10. Particularly, among the two second shock pads 81, only the front second shock pad 81 is used for passing through the fastening bolt 91, that is, the rear second shock pad 81 only plays a shock absorption effect and no fastener 90 is provided. Of course, in order to make the parts have universality and replaceability, first through holes 82 are provided on both second shock pads 81, but no fastener 90 is provided on the rear second shock pad 81 (as can be seen in combination Figure 13 ). Therefore, those skilled in the art can understand that it is also a feasible implementation manner not to provide a hole structure on the rear second shock pad 81.

[0070] Furthermore, a gap of 0.3 - 0.5 mm is reserved between the upper end surface of the second shock pad 81 and the inner wall surface of the upper installation cavity 21, which can not only fix the second shock pad 81 up and down, but also the reserved gap allows the second shock pad 81 to have a certain vibration space.

[0071] As Figure 7 shown, in the technical solution of this embodiment, a limiting boss 24 matching with the end of the installation side 11 is provided on the inner wall of the installation cavity 21. Specifically, the limiting boss 24 is used to limit the rear end of the installation side 11 to fix the pump body 10 in the installation cavity 21.

[0072] Preferably, the pump body 10 in this embodiment is a pressure stabilizing pump. Specifically, a plurality of filters are further provided on the second mounting bracket 30, and both ends of the connecting pipe 60 are respectively connected to the pump body and the filter. Of course, the above pump body 10 can be other types of pump structures.

[0073] This embodiment also provides a household appliance, and the household appliance includes the shock absorption structure of the pump body, and the shock absorption structure of the pump body is the above shock absorption structure.

[0074] Preferably, the household appliance in this embodiment is a water purifier. Of course, any household appliance equipped with a pump structure can adopt the vibration damping structure of the above pump body.

[0075] According to the above structure, the pump body vibration damping structure of this application has the following advantages:

[0076] 1. Through the double-layer vibration damping system of this application, the pressure stabilizing pump is fixed to the whole machine bracket (the second mounting bracket 30 in this embodiment) or the fuselage through vibration damping rubber pads during operation, avoiding rigid contact and reducing problems such as vibration generated during operation.

[0077] 2. By designing a second vibration damping member 70 in the inlet and outlet pipes of the pressure stabilizing pump and fixing it to the mounting seat 32 or the receiving recess 33 in an interference fit manner, the vibration of the inlet and outlet pipes is reduced.

[0078] 3. This application designs a cover (the cover body 34 in this example) that cooperates with the whole machine bracket (the mounting seat 32 in the embodiment), so that the pressure stabilizing pump assembly fixed to the mounting bracket (the first mounting bracket 20 in this embodiment) is placed in a relatively sealed space, and sound-absorbing materials are laid at the pump tail of the pressure stabilizing pump for sound absorption treatment, thereby achieving a noise reduction effect.

[0079] This application adopts a double-layer vibration damping system, enabling the pressure stabilizing pump to be initially vibration-damped by being fixed to the first mounting bracket 20 through rubber pads and bolt assemblies, and then the first mounting bracket 20 with vibration damping rubber pads is fixed to the second mounting bracket 30 to complete the secondary vibration damping, realizing the double-layer vibration damping system and solving the noise problem caused by excessive vibration in existing products. This application designs a vibration damping rubber pad for the inlet and outlet pipes. Through interference fit with the cover and the whole machine bracket, stability is ensured, its vibration is reduced, collision between the pipeline and the cover and the bracket is avoided, and in combination with sound-absorbing materials, the noise reduction effect is achieved, reducing the noise generated inside the whole machine due to vibration, and a sponge sleeve is wrapped around the outlet pipeline for vibration reduction and noise reduction again.
