[0030] Optionally, the pump body 100 can be in the form of a negative pressure pump, etc., which is not limited here.

[0031] As Figures 1 to 4 shown in one embodiment, a pump body mounting structure 200 is provided, comprising a damping element 210 and a base 220.

[0032] As Figure 1 and Figure 4 shown, optionally, the base 220 is provided with a noise reduction through hole 221.

[0033] The base 220 can be in the form of a plate or the like.

[0034] As shown in Figures 1 to 3 Optionally, the damping element 210 is arranged on the base 220, the damping element 210 is provided with a damping cavity 211, the side of the damping element 210 facing the base 220 is provided with an opening 212, the opening 212 is in communication with the noise reduction through hole 221 and the damping cavity 211, and the side of the damping element 210 away from the base 220 is connected and fixed to the pump body 100 in a clamping or screwing manner or the like.

[0035] The opening 212 can be designed according to specific installation requirements, for example, when the pump body 100 is connected and fixed above the damping element 210, the opening 212 is located at the bottom of the damping element 210.

[0036] The damping element 210 can be made of a material such as silicone, which can effectively absorb or buffer the mechanical energy generated by vibration, thereby achieving the effect of damping and noise reduction.

[0037] The pump body mounting structure 200 of the above embodiment connects the pump body 100 and the damping element 210, and the vibration and noise generated during the operation of the pump body 100 are transmitted to the damping element 210, which absorbs and buffers the vibration and noise through the deformation of the damping cavity 211 of the damping element 210, thereby achieving the effect of damping and noise reduction. In addition, the mechanical energy generated by the noise in the damping cavity 211 can also be transmitted and released through the noise reduction through hole 221, which can effectively reduce the probability of resonance and improve the effect of damping and noise reduction.

[0038] As shown in Figure 3 In one embodiment, the side of the damping element 210 away from the base 220 is provided with a connecting through hole 213, and a first connecting member for connecting the damping element 210 and the pump body 100 is arranged in the connecting through hole 213, so that the vibration and noise generated during the operation of the pump body 100 can be transmitted to the damping element 210 for damping and noise reduction.

[0039] Optionally, the bottom of the pump body 100 can be connected to the top of the damping element 210.

[0042] As shown in Figure 2 andFigure 3 As shown, in one embodiment, the profile of the damping cavity 211 is semispherical, so that the mechanical energy transmitted into the damping cavity 211 converges towards the center of the damping cavity 211, i.e. the mechanical energy of different sizes and irregular directions is converted into regular centripetal force, which is conducive to reducing the probability of resonance and significantly improving the effect of damping and noise reduction.

[0043] Optionally, the center axis of the connecting through hole 213 passes through the center of the damping cavity 211, which is more conducive to the mechanical energy transmitted by the pump body 100 into the damping cavity 211 converging towards the center of the damping cavity 211 and being converted into regular centripetal force.

[0044] Optionally, the center axis of the noise reduction through hole 221 passes through the center of the damping cavity 211, so that the centripetal force converging to the center of the damping cavity 211 is transmitted and released through the noise reduction through hole 221, which can effectively reduce the probability of resonance and further improve the effect of damping and noise reduction.

In this way, the connecting plane 214 can be attached to the pump body 100 to realize surface connection, which is conducive to the pump body 100 transmitting vibration and noise into the damping cavity 211 of the damping element 210.

[0046] As shown, Figure 2 and Figure 3 Optionally, the side of the damping element 210 provided with the opening 212 is provided with a connecting flange 215, and the damping element 210 is connected with the base 220 through the connecting flange 215.

In this way, the mechanical energy transmitted and released through the noise reduction through hole 221 is reflected and collided and absorbed by the plurality of noise reduction bosses 232 during transmission in the noise reduction channel 231, which can effectively improve the damping and noise reduction effect. And, the plurality of noise reduction bosses 232 with different heights make the noise reduction channel 231 present a wave peak and wave trough undulating structure, which is beneficial to multiple reflections and absorptions of mechanical energy, improving the damping and noise reduction effect.

[0052] Among them, the number of noise reduction bosses 232 can be flexibly adjusted or designed according to actual use needs, which is not limited here.

[0053] Optionally, the noise reduction boss 232 can be a table structure with a honeycomb energy absorption structure on the surface.

[0054] As shown, Figure 5 Further, the noise reduction element 230 is provided with an energy absorption hole 233, and at least part of the energy absorption hole 233 communicates with the noise reduction channel 231. In this way, the energy absorption hole 233 can be used to further release the mechanical energy in the noise reduction channel 231, which can further reduce the probability of resonance and further improve the damping and noise reduction effect.

[0055] Optionally, a plurality of noise reduction bosses 232 are arranged to form a convex group, a plurality of convex groups are arrayed at a predetermined interval, and the energy absorption hole 233 is arranged between adjacent convex groups. In this way, the noise reduction channel 231 presents an irregular structure with different widths and depths, which is beneficial to multiple reflections and absorptions of mechanical energy, improving the damping and noise reduction effect. Combined with the release effect of the energy absorption hole 233, the probability of resonance can be further reduced, and the damping and noise reduction effect can be further improved.
