Description

Technical Field

[0001] This utility model relates to the technical field of massage devices, and in particular to a shock absorption device for an air pump. Background Technology

[0002] Existing massage devices, such as massage mattresses and massage chairs, generally provide the power required for massage through drive components such as air pumps and vibration motors. In particular, air pumps vibrate during use. Since the drive components are connected to the housing, the drive components can easily cause the housing to vibrate and generate noise, affecting the user experience. However, the existing shock absorption devices have poor shock absorption effects, so they need to be improved. Summary of the Invention

[0003] The purpose of this invention is to provide a shock-absorbing device for an air pump. By using a shock-absorbing element inside the housing, the elastic deformation of the elastic protrusion of the shock-absorbing element can effectively reduce vibration transmission, thereby providing a better shock-absorbing effect on the housing.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a shock absorption device for an air pump, comprising...

[0005] The housing includes a first housing and a second housing that are detachably connected as a single unit;

[0006] The vibration damping element includes a first vibration damper and a second vibration damper. The first vibration damper is fixedly connected to a first housing, and the second vibration damper is fixedly connected to a second housing. The first and second vibration dampers enclose and form an accommodating space. The first and second vibration dampers have multiple elastic protrusions on the side facing the accommodating space. The elastic protrusions have a hollow structure inside. The vibration damping element and the housing cooperate to form a wiring channel.

[0007] An air pump is fixedly housed within a housing space. The first end of the air pump is attached to the elastic protrusion of the first shock absorber, and the second end of the air pump is attached to the elastic protrusion of the second shock absorber. The vibration generated when the air pump is working will force the elastic protrusion to deform elastically, and the elastic deformation of the elastic protrusion can play a shock-absorbing role.

[0008] Furthermore, the first shock absorber includes a left shock absorber and a right shock absorber that are separately disposed. The left shock absorber and the right shock absorber are respectively fixedly connected to the first housing. A first channel is formed between the left shock absorber and the right shock absorber through which the connecting pipe of the air supply pump passes. The first housing is provided with a second channel corresponding to the first channel.

[0009] Furthermore, both the left and right shock absorbers include a bottom and a sidewall surrounding the outer periphery of the bottom. The sidewall is disposed on the outer periphery of the accommodating space, and the elastic protrusion is disposed on the bottom. Multiple connecting ribs are arranged on the side of the sidewall facing the accommodating space, and the connecting ribs are used to define the position of the air pump.

[0010] Furthermore, the elastic protrusion has a protruding end and a fixed end, the fixed end is connected to the corresponding shock absorber, the protruding end faces the accommodating space, and the outer diameter of the elastic protrusion increases from the protruding end to the fixed end.

[0011] Furthermore, the inner ends of the first and second housings are provided with connecting posts, and the first and second shock absorbers are provided with insertion holes. The first and second shock absorbers are fixedly connected to the corresponding housings through the connecting posts and insertion holes.

[0012] Furthermore, the bottom of the air pump has a structure that is low in the middle and high at both ends. The height of the elastic protrusion on the first shock absorber matches the structure of the bottom of the air pump that is low in the middle and high at both ends, so that the elastic protrusion on the first shock absorber is in contact with the bottom of the air pump.

[0013] Furthermore, the first housing and the first shock absorber, and the second housing and the second shock absorber are respectively fixedly connected by fasteners.

[0014] Furthermore, both the first and second shock absorbers are made of silicone.

[0015] Furthermore, at least one set of elastic connecting arms is provided on each side of the first housing. Each elastic connecting arm has a free end and a connecting end. The connecting end is fixedly connected to the first housing, and a connecting part is provided on the free end. The first housing is fixedly connected to the required position through the connecting part of the free end. The vibration generated when the air pump is working can drive the elastic connecting arm to elastically deform, thereby playing a shock absorption role.

[0016] Furthermore, the first housing is suspended within the electrical control box via an elastic connecting arm.

[0017] Furthermore, the elastic connecting arm is integrally injection molded with the first housing.

[0018] In summary, this utility model has the following beneficial effects:

In addition, the connecting ribs can also deform to buffer the vibration of the air pump.

[0021] 3. The shock absorption device for the air pump of this utility model has elastic connecting arms set on both sides of the first housing, so that the air pump is in a suspended state, which reduces noise. At the same time, the elastic deformation of the elastic connecting arms further reduces shock. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] like Figures 1-6As shown, a shock-absorbing device for an air pump includes a housing 10, a shock-absorbing element 20, and an air pump 30. These constitute the technical structure of this utility model. The housing 10 includes a first housing 11 and a second housing 12 that are detachably connected as a single unit. The connection method between the first housing 11 and the second housing 12 includes, but is not limited to, fastener connection. The shock-absorbing element 20 includes a first shock-absorbing component 21 and a second shock-absorbing component 22. The first shock-absorbing component 21 is fixedly connected to the first housing 11, and the second shock-absorbing component 22 is fixedly connected to the second housing 12. The first shock-absorbing component 21 and the second shock-absorbing component 22 enclose and form an accommodating space. The first shock-absorbing component 21 and the second shock-absorbing component 22 protrude towards the accommodating space. Multiple elastic protrusions 23 are provided, and the interior of each elastic protrusion 23 is hollow. The hollow structure of the elastic protrusions 23 facilitates their deformation, thereby achieving a better shock absorption effect. The shock absorption element 20 and the housing 10 cooperate to form a wiring channel 24, which can be used for cables and / or air pipes to pass through. The air pump 30 is fixedly housed in the housing space. The first end of the air pump 30 is attached to the elastic protrusion 23 of the first shock absorber 21, and the second end of the air pump 30 is attached to the elastic protrusion 23 of the second shock absorber 22. The vibration generated when the air pump 30 is working will force the elastic protrusions 23 to elastically deform, and the elastic deformation of the elastic protrusions 23 can achieve a shock absorption effect.

[0031] In some embodiments, the first shock absorber 21 includes a left shock absorber 211 and a right shock absorber 212 that are separately disposed. The left shock absorber 211 and the right shock absorber 212 are respectively fixedly connected to the first housing 11. A first channel 241 is formed between the left shock absorber 211 and the right shock absorber 212 through which the connecting pipe of the air pump 30 passes. The first housing 11 is provided with a second channel 242 that corresponds to the first channel 241. The first channel 241 and the second channel 242 cooperate to form a wiring channel 24. Of course, the first shock absorber 21 can also be configured as an integral structure, that is, the left shock absorber 211 and the right shock absorber 212 are configured as an integral part.

[0032] Furthermore, both the left damper 211 and the right damper 212 include a bottom 213 and a sidewall 214 surrounding the bottom 213. The sidewall 214 is disposed around the outer periphery of the accommodating space. The elastic protrusions 23 are arranged on the bottom 213. Multiple connecting ribs 215 are arranged on the side of the sidewall 214 facing the accommodating space. The connecting ribs 215 are used to limit the position of the air pump 30. The connecting ribs 215 are provided on the inner walls of the left damper 211 and the right damper 212. The connecting ribs 215 serve to strengthen the structure and limit the air pump 30 to prevent it from shaking in the accommodating space. In addition, the connecting ribs 215 can also deform to buffer the vibration of the air pump 30.

[0033] In some embodiments, the elastic protrusion 23 has a protruding end 231 and a fixed end 232, the fixed end 232 is connected to the corresponding damping member, the protruding end 231 faces the accommodating space, and the outer diameter of the elastic protrusion 23 increases from the protruding end 231 to the fixed end 232. By setting the outer diameter of the elastic protrusion 23, the elastic protrusion 23 can effectively deform axially, thereby improving the damping effect.

[0034] In some embodiments, the inner ends of the first housing 11 and the second housing 12 are provided with connecting posts 13, and the first shock absorber 21 and the second shock absorber 22 are provided with insertion holes 25. The first shock absorber 21 and the second shock absorber 22 are fixedly connected to the corresponding housing 10 by the connecting posts 13 and the insertion holes 25. Specifically, multiple sets of connecting posts 13 are formed on the inner end faces of the first shock absorber 21 and the second shock absorber 22, and column portions corresponding to the connecting posts 13 are formed on the first shock absorber 21 and the second shock absorber 22. Insertion holes 25 that are inserted into the column portions are provided.

[0035] In some embodiments, the bottom of the air pump 30 has a structure that is low in the middle and high at both ends. The height of the elastic protrusion 23 on the first shock absorber 21 matches the structure of the bottom of the air pump 30 that is low in the middle and high at both ends, so that the elastic protrusion 23 on the first shock absorber 21 are all in contact with the bottom of the air pump 30. Through this setting, the first shock absorber 21 can more stably support and dampen the air pump 30.

[0036] In some embodiments, the first housing 11 and the first shock absorber 21, and the second housing 12 and the second shock absorber 22 are respectively fixedly connected by fasteners. Of course, the first housing 11 and the first shock absorber 21, and the second housing 12 and the second shock absorber 22 can also be connected by other detachable methods, such as bonding, fastening, etc.

[0037] In some embodiments, the first damping member 21 and the second damping member 22 are both made of silicone. Silicone can provide a certain damping effect on the air pump 30 through its elasticity and deformation ability.

[0038] In some embodiments, at least one set of elastic connecting arms 14 are respectively provided on both sides of the first housing 11. Each elastic connecting arm 14 has a free end 141 and a connecting end 142. The connecting end 142 is fixedly connected to the first housing 11, and a connecting portion is provided on the free end 141. The first housing 11 is fixedly connected to a desired position via the connecting portion of the free end 141. For example, the first housing 11 may be suspended within an electrical control box via the elastic connecting arms 14. The vibration generated when the air pump 30 operates can drive the elastic connecting arms 14 to elastically deform, thereby achieving a vibration damping effect. By providing elastic connecting arms 14 on both sides of the first housing 11, the air pump 30 is suspended, reducing noise, while the elastic deformation of the connecting arms 14 further reduces vibration.

[0039] The elastic connecting arm 14 and the first housing 11 are integrally injection molded. Integral injection molding can improve strength and reduce production costs. Specifically, the free end 141 of the elastic connecting arm 14 is provided with an assembly hole. Fasteners are inserted into the assembly hole to fix the elastic connecting arm 14 to the required position.

[0040] The shock absorption device of the air pump 30 of this utility model can effectively reduce the transmission of vibration by means of the shock absorption element 20 in the housing 10 and the elastic deformation of the elastic protrusion 23, thereby achieving a better shock absorption effect on the housing 10.

[0041] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
