[0004] After the analysis of the search and the long-time research and continuous experiments of the applicant in the field, it is found that the above-mentioned way of reducing noise is too simple and common, and the use of the sound insulation board alone is not enough to reduce the noise generated by the air pump, and it cannot reduce the noise for multiple times, therefore, it is necessary to provide a new low-noise air pump. SUMMARY

[0005] In order to solve the above technical problems, the present application provides a new low-noise air pump to solve the technical problems that the way of reducing noise in the existing low-noise air pump is too simple and common, and the use of the sound insulation board alone is not enough to reduce the noise generated by the air pump, and it cannot reduce the noise for multiple times.

[0006] The purpose of the present application is achieved by the following specific technical means:

[0007] A novel low-noise air pump includes an air pump body, an outer protective shell fitted over the air pump body, and a damping arc tube evenly fixed to the outer wall of the upper and lower ends of the air pump body. Sound-absorbing plates are fixed to both sides of the inner walls of the damping arc tube, and a damping spring is fixed to the middle of the damping arc tube. Mounting frames are provided on the inner walls of both sides of the protective shell, and vertical plates are evenly fixed to the lower ends of the mounting frames. Horizontal plates are evenly fixed between the vertical plates, and corrugated tubes are evenly inserted through the top of the horizontal plates away from the lower ends of the mounting frames. A fixing plate is inserted through the upper ends of the corrugated tubes, and a flow divider is fixed to the inner walls of both sides of the protective shell corresponding to the upper ends of the fixing plates. A guide groove is provided in the middle of the upper end of each flow divider, and an outlet hole is provided on the protective shell corresponding to one side of the flow divider.

[0008] Preferably, the deceleration arc tube also includes a sliding block, and the other end of the deceleration spring provided in the middle of the deceleration arc tube is fixed to the inner wall of the protective shell. At the same time, the deceleration arc tube is made of spring steel plate, and the convex side of the deceleration arc tube is fixed to the outer wall corresponding to the air pump body. Sliding blocks are fixedly provided at both ends of the top of the deceleration arc tube. The top of the sound-absorbing plate provided inside the deceleration arc tube is uniformly provided with round holes, and the outer wall of the deceleration arc tube is also provided with round holes of the same size as the sound-absorbing plate.

[0009] Preferably, the protective housing also includes a sliding groove, and sliding grooves are provided on the inner walls of both the upper and lower ends of the protective housing. The sliding blocks provided on the arc-shaped tube are all slidably disposed in the corresponding sliding grooves.

[0010] Preferably, the mounting frame also includes through holes, forming a grid between the vertical and horizontal plates, and through holes are provided on the horizontal plates between the grids, with the through holes between the horizontal plates corresponding to each other. The through holes provided on the horizontal plates away from the lower end of the mounting frame correspond to the corrugated pipe.

[0011] Preferably, the interior of the wave tube is hollow, and the upper end of the fixing plate penetrating through the other end of the wave tube is provided with corresponding round holes, and the fixing plate is made of rubber.

[0012] Preferably, the diverter plates on both sides of the mounting frame are staggered, and the openings of the guide grooves on the upper part of the diverter plates correspond to the outlet holes on the protective shell, and the shape and size of the diverter plates are consistent.

[0013] Preferably, the inner walls on both sides and the bottom of the mounting frame are filled with sound-absorbing material.

[0014] Beneficial effects:

[0015] 1. This utility model provides comprehensive protection for the air pump body through its protective casing, thereby reducing damage to the air pump body. Simultaneously, the design of the cushioning arc tube allows force to be applied to the protective casing when it is subjected to external impacts or pressure, thus mitigating the compression deformation of the arc tube. Furthermore, the cushioning spring helps to abut the arc tube, effectively protecting the casing from impacts and pressure. Additionally, during air pump operation, noise emitted can enter the sound-absorbing plate through the circular holes on the outer wall of the cushioning arc tube, achieving effective sound absorption and reducing noise generation.

[0016] 2. When the air pump body generates noise during use, the noise can be channeled between the vertical and horizontal plates in the mounting frame on both sides of the inner wall of the protective shell. When the noise enters between the vertical and horizontal plates, it will circulate between the vertical and horizontal plates through the through hole, thus achieving initial noise reduction.

[0017] 3. Secondly, when the noise enters the corrugated pipe through the through hole, the corrugated pipe is designed to reduce the noise again. When the noise passes through the corrugated pipe and enters between the diverter plates, the noise can be diverted and reduced between the diverter plates. After being reduced multiple times, the noise is discharged from the outlet hole under the action of the guide groove, so that the final discharge has a low noise effect. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example:

[0028] As attached Figure 1 To be continued Figure 6 As shown: A novel low-noise air pump includes an air pump body 1, a protective shell 2 fitted around the air pump body 1, and a damping arc tube 3 uniformly fixedly arranged on the outer wall of the upper and lower ends of the air pump body 1. Sound-absorbing plates 32 are fixedly arranged on both sides of the inner wall of the damping arc tube 3, and a damping spring 33 is fixedly arranged in the middle of the damping arc tube 3. Mounting frames 4 are provided on the inner walls of both sides of the protective shell 2, and vertical plates 41 are uniformly fixedly arranged at the lower end of the mounting frames 4. Horizontal plates 42 are uniformly fixedly arranged between the vertical plates 41, and corrugated pipes 44 are uniformly inserted through the top of the horizontal plates 42 away from the lower end of the mounting frames 4. A fixing plate 45 is inserted through the upper end of each corrugated pipe 44, and a flow divider plate 46 is fixedly arranged on the inner walls of both sides of the protective shell 2 corresponding to the upper end of the fixing plate 45. A guide groove 47 is provided in the middle of the upper end of each flow divider plate 46, and an outlet hole 22 is provided on the protective shell 2 corresponding to one side of the flow divider plate 46.

[0029] The damping arc tube 3 also includes a sliding block 31. The damping spring 33 in the middle of the damping arc tube 3 is fixed to the inner wall of the protective shell 2 at the other end. The damping arc tube 3 is made of spring steel plate, and the convex side of the damping arc tube 3 is fixed to the outer wall corresponding to the air pump body 1. Sliding blocks 31 are fixed to both ends of the top of the damping arc tube 3. The top of the sound-absorbing plate 32 inside the damping arc tube 3 is uniformly provided with round holes, and the outer wall of the damping arc tube 3 is also provided with round holes of the same size as those on the sound-absorbing plate 32. The setting of the damping arc tube 3 allows it to abut and restore itself under the action of the damping arc tube 3 and the damping spring 33 when the protective shell 2 is impacted or squeezed, thereby reducing the damage to the protective shell 2 and the air pump body 1. Moreover, the setting of the sound-absorbing plate 32 inside the damping arc tube 3 not only protects the air pump body 1 but also achieves the effect of reducing noise.

[0030] The protective shell 2 also includes a sliding groove 21. The inner walls of the upper and lower ends of the protective shell 2 are provided with sliding grooves 21. The sliding blocks 31 provided on the arc-shaped tube 3 are slidably disposed in the corresponding sliding grooves 21. The sliding grooves 21 and sliding blocks 32 are correspondingly arranged so that when the arc-shaped tube 3 is squeezed, the sliding blocks 32 can slide and extend in the sliding grooves 21 to a certain extent, thereby achieving the protection of the arc-shaped tube 3.

[0031] The mounting frame 4 also includes through holes 43. The vertical plate 41 and the horizontal plate 42 form a grid, and the horizontal plate 42 between the grids is provided with through holes 43. The through holes 43 between the horizontal plates 42 are all corresponding to each other. The through holes 43 provided on the horizontal plate 42 away from the lower end of the mounting frame 4 are all corresponding to the corrugated pipe 44. The arrangement of the vertical plate 41 and the horizontal plate 42 in the mounting frame 4 allows noise to circulate through the through holes 43 in the grid formed by the vertical plate 41 and the horizontal plate 42 when it enters between the vertical plate 41 and the horizontal plate 43, thereby achieving the initial effect of noise reduction.

[0032] The interior of the wave tube 44 is hollow, and the upper end of the fixing plate 45 through which the wave tube 44 passes is provided with corresponding round holes. The fixing plate 45 is made of rubber. The shape of the wave tube 44 itself can reduce the noise entering the interior to a certain extent, thereby achieving the effect of further reducing noise.

[0033] The diversion plates 46 on both sides of the mounting frame 4 are staggered, and the openings of the guide grooves 47 on the upper end of the diversion plates 46 correspond to the outlet holes 22 on the protective shell 2. The shape and size of the diversion plates 46 are consistent. The diversion plates 46 and the guide grooves 47 are designed to facilitate the final reduction of noise flow, and the guide grooves 47 can guide the final noise to be discharged from the outlet holes 22, thereby achieving the effect of low noise discharge.

[0034] The inner walls on both sides and the bottom of the mounting frame 4 are filled with sound-absorbing material, which further reduces noise.

[0035] Working Principle: Firstly, the protective outer shell 2 provides comprehensive protection for the air pump body 1, thereby reducing damage to the air pump body 1. Simultaneously, the inclusion of the cushioning arc tube 3 allows the protective outer shell 2 to withstand external impacts and pressures, applying force to the cushioning arc tube 3 to reduce its deformation. Furthermore, the cushioning spring 33 acts as a stop mechanism for the cushioning arc tube 3. This deformation also compresses the sliding blocks 31 at both ends, causing them to slide and extend within the sliding groove 21, further reducing damage to the cushioning arc tube 3 during contact. This effectively protects the outer shell 2 from external impacts and pressures. Additionally, sound emitted during air pump body 1 operation can enter the sound-absorbing plate 32 through the circular holes on the outer wall of the cushioning arc tube 3, achieving effective sound absorption. The effect is to reduce noise generation. When the air pump body 1 makes noise during use, the noise can enter between the vertical plate 41 and the horizontal plate 42 in the mounting frame 4 on both sides of the inner wall of the protective shell 2. When the noise enters between the vertical plate 41 and the horizontal plate 42, it will circulate between the vertical plate 41 and the horizontal plate 42 through the through hole 43, thus achieving the initial reduction of noise. Finally, when the noise enters the corrugated pipe 44 through the through hole 43, the noise will be reduced again under the corrugated pipe 44. When the noise passes through the corrugated pipe 44 and enters between the diverter plates 46, the noise can be diverted and reduced between the diverter plates 46. After being reduced multiple times, the noise is discharged from the outlet hole 22 under the action of the guide groove 47, thus achieving the final effect of low noise discharge.
