The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by technicians in the technical field of the present invention. The terms used in this specification are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0025] See also Figure 1 Combined with Figure 2, an air pump 1000, comprising a buffer component 1, a shell 4, an air pump body 2, an air inlet pipe 3, a shell 4, and an air outlet pipe 5, the shell 4 defines a cavity (not marked), the buffer component 1 is arranged in the cavity, the air pump body 2 is located in the shell 4, the buffer component 1 is used to achieve shock absorption of the air pump 1000, the air pump body 2 is accommodated in the buffer component 1, one end of the air inlet pipe 3 is connected to the air inlet end of the air pump body 2, one end of the air inlet pipe 3 extends out of the cavity, one end of the air outlet pipe 5 is connected to the air outlet end of the air pump body 2, one end of the air outlet pipe 5 extends out of the cavity, the air inlet pipe 3 is used to provide a transmission channel when gas is drawn into the air pump 1000 under negative pressure, and the air outlet pipe 5 is used to provide a transmission channel when the air in the air pump body 2 is pumped into an external device.

[0026] It is understandable that the air inlet pipe 3 and the air outlet pipe 5 can be flexible hoses, PCV hard pipes, metal pipes, etc. The flexible hoses can alleviate the vibration transmitted to the outside through the air inlet pipe and the air outlet pipe to a certain extent.

[0027] For the above buffer component 1, please combine Figure 3 and Figure 4 The buffer assembly 1 includes a buffer sleeve 11 and an elastic member 12. The air pump body 2 is sleeved in the buffer sleeve 11, and the buffer sleeve 11 is fixed in the shell 4. The buffer sleeve 11 is used to buffer the vibration generated by the air pump body 2 in the working state, wherein the material of the buffer sleeve 11 is a flexible material. One end of the elastic member 12 is fixed to the outer surface of the shell 4, and the other end of the elastic member 12 is used to be fixed to an external device. The air pump 1000 is connected to the external device through the elastic member 12. The elastic member 12 is used to convert the vibration generated by the air pump body 2 driving the shell 4 into the elastic shaking of the elastic member 12, further improving the shock absorption capacity of the buffer assembly 1 to the air pump 1000. Under the cooperation of the elastic member 12 and the buffer sleeve 11, the shock absorption effect of the air pump of the utility model is greatly improved. In addition, the fixing methods of the elastic member 12 and the shell 4, and the fixing methods of the elastic member 12 and the external device include but are not limited to screw connection, clamping connection, adhesive connection, welding, etc.

[0028] It can be understood that the buffer bushing 11 made of flexible material includes but is not limited to rubber, sponge, foam, EVA, ACF shock-absorbing material, etc. In this embodiment, the material of the buffer bushing 11 is preferably a rubber material with a hardness of 40 degrees. The rubber material has better comprehensive performance and lower cost. Considering the comprehensive buffering performance and cost, the rubber material with a hardness of 40 is more suitable for mass industrial production.

[0029] For the above-mentioned buffer bushing 11, please refer to Figure 1 and Figure 3 The buffer sleeve 11 is provided with a hanging sleeve 111, and the hanging sleeve 111 is fixed to the buffer sleeve 11, wherein the number of the hanging sleeves 111 is at least two, and the hanging sleeves 111 are connected to the outer periphery of the buffer sleeve 11. The connection method between the hanging sleeve 111 and the support column 47 includes but is not limited to plugging, clamping, gluing, etc. In this embodiment, a mounting hole (not shown) is formed on the hanging sleeve 111, and the hanging sleeve 111 is detachably connected to the support column 47 through the mounting hole, and the inner wall of the mounting hole is connected to the support column 47 is an interference fit, and a hanging sleeve 111 is inserted into the support column 47; the hanging sleeve 111 is inserted into the support column 47 to suspend the buffer sleeve 11 in the cavity of the shell 4, and the air pump body 2 is accommodated in the buffer sleeve 11, so that the air pump body 2 is suspended in the shell 4. The suspended air pump body 2 makes the vibration of the air pump body 2 in the working state no longer directly contact with the shell 4, and the vibration is no longer directly transmitted to the shell 4, thereby enhancing the shock absorption effect of the buffer assembly 1.

[0030] It can be understood that the mounting hole can be a through hole, the support column 47 extends out of the mounting hole, and the top of the mounting hole can also be closed. The closed mounting hole plays a certain limiting role, so that the buffer bushing 11 will not slide down along the support column 47.

[0031] It can be understood that the number of the hanging sleeve 111 is multiple, including but not limited to two, as long as the buffer sleeve 11 fixed thereto can be suspended in the air. In some embodiments, the buffer sleeve 11 is not provided with a hanging sleeve 111, but the buffer sleeve 11 is directly fixed on the support column 47 to achieve the effect of suspending the air pump body 2 in the air.

[0032] For the above shell 4, please combine Figure 5 and Figure 6The shell 4 includes an upper cover 41, a lower shell 42, an annular rib 43, a reinforcing rib 44, a first through hole 45, a second through hole 46, and a support column 47. The upper cover 41 and the lower shell 42 cover and define the cavity. One end of the support column 47 is fixed to the inner surface of the cavity, that is, one end of the support column 47 is fixed to the bottom wall of the lower shell 42. The hanging sleeve 111 of the buffer bushing 11 is connected to the other end of the support column 47. The annular rib 43 is arranged on the shell 4. The outer surface, and the annular convex rib 43 and the bottom plate of the shell 4 are enclosed together to define a limiting groove (not marked), one end of the elastic member 12 is accommodated in the limiting groove, and the other end of the elastic member 12 is used to be fixed on an external device, and the limiting groove is used to limit the elastic member 12 accommodated in the limiting groove, so that the elastic member 12 is fixed in the limiting groove, and the vibration of the air pump body 2 will not drive the shell 4 to vibrate, thereby causing the elastic member 12 to escape from the limiting groove. The reinforcing rib 44 is arranged on the bottom wall of the lower shell 42, and the reinforcing rib 44 is a mesh structure located on the bottom wall inside the lower shell 42. The reinforcing rib 44 can enhance the strength of the shell 4, and can also realize diffuse reflection of the noise generated by the air pump body 2. The noise belongs to sound waves. The uneven inner wall makes the noise present a diffuse reflection propagation state in the shell 4, changing its propagation path, and isolating the noise in the shell 4, so as to achieve the effect of reducing the noise of the air pump body 2. The first through hole 45 and the second through hole 46 are both connected to the cavity; the first through hole 45 is used for the air inlet pipe 3 to extend out of the cavity, and the second through hole 46 is used for the air outlet pipe 5 to extend out of the cavity. The first through hole 45 and the second through hole 46 respectively accommodate the air inlet pipe 3 and the air outlet pipe 5 and provide channels for communication with the outside world.

[0033] It is worth noting that the number of the support columns 47 is at least two, and the support columns 47 are greater than or equal to the number of the hanging sleeves 111. For example, when the number of the hanging sleeves 111 is two, the number of the support columns 47 can be any positive integer such as 2, 3, 4, etc. The support columns 47 are greater than the number of the hanging sleeves 111, so that the installation angle of the hanging sleeves 111 in the shell 4 can be adjusted. For example, there are two hanging sleeves 111 and six support columns 47. The hanging sleeves 111 are plugged into different support columns 47 to adjust the installation angle.

[0034] It is understandable that the shape of the annular rib 43 includes but is not limited to a circle, a square, an ellipse or any other shape, as long as the annular rib 43 can limit the elastic member 12 .

[0035] In some embodiments, the elastic member 12 is a spring, a spring sheet, etc. In this embodiment, the elastic member 12 is preferably a spring.

[0036] In some embodiments, the first through hole 45 and the second through hole 46 are arranged adjacent to each other, and half of the first through hole 45 is located in the upper cover 41, and the other half is located in the lower shell 42, and the upper cover 41 and the lower shell 42 are covered together to form the first through hole 45. This structural design allows the air inlet pipe 3 to be clamped by the upper cover 41 and the lower shell 42, which facilitates the installation and replacement of the air inlet pipe 3. Similarly, half of the second through hole is located in the upper cover 41, and the other half is located in the lower shell 42, and the upper cover 41 and the lower shell 42 are covered together to form the second through hole 46. This structural design allows the air outlet pipe 5 to be clamped by the upper cover 41 and the lower shell 42, which facilitates the installation and replacement of the air outlet pipe 5.

[0037] In some embodiments, see Figure 5 The support column 47 also includes a limiting portion 471, which is arranged around the support column 47 and extends radially outward from the support column. The limiting portion 31 is used to abut the hanging sleeve 111 to limit the hanging sleeve 111, so that when the hanging sleeve 111 is mounted on the support column 47, the hanging sleeve 111 will not gradually slide down to the connection between the support column 47 and the shell 4 due to the deadweight of the air pump body 2 and the vibration of the air pump body 2 in the working state.

[0038] It can be understood that the limiting portion 471 includes but is not limited to structures such as steps and reinforcing ribs 44. In this embodiment, the limiting portion 471 is preferably a vertical rib structure, which not only strengthens the structural strength of the support column 47, but also plays a supporting and limiting role.

[0039] Another embodiment provided by the present utility model is: a control device is provided, including a bracket, a controller and the above-mentioned air pump 1000. The structure and function of the air pump 1000 can be referred to the above-mentioned embodiment, and will not be described one by one here; the air pump 1000 is fixed to the bracket, and the other end of the elastic member 12 on the air pump 1000 is fixed to the bracket, and the air pump 1000 is connected to the bracket through the elastic member 12, and the elastic member 12 itself The characteristics of the air pump 1000 and the bracket are used to achieve buffering between the air pump 1000 and the bracket to achieve a shock absorbing effect. The controller is arranged on the bracket, and the controller is electrically connected to the air pump 1000 for controlling the start and stop of the air pump 1000.

[0040] Another embodiment provided by the utility model is to provide an airbag bed, comprising: an airbag and the above-mentioned control device, wherein an air pump 1000 of the control device is connected to the airbag, and the air pump 1000 is used to inflate and discharge gas for the airbag.

[0041] The beneficial effects of the embodiment of the utility model are as follows: an air pump 1000, a control device and an airbag bed are provided, wherein the air pump 1000 comprises a shell 4, an air pump body 2, a support column 47, a buffer assembly 1, an air inlet pipe 3 and an air outlet pipe 5, wherein the shell 4 is provided with a cavity, one end of the support column 47 is fixed to the shell 4 on the inner surface of the cavity, wherein the number of the support columns 47 is four, and the four support columns 47 are symmetrically arranged in the cavity, and the air pump body 2 is located in the shell 4, the buffer assembly 1 is used to achieve shock absorption of the air pump 1000, one end of the air inlet pipe 3 is connected to the air inlet end of the air pump 1000, one end of the air inlet pipe 3 extends out of the cavity, one end of the air outlet pipe 5 is connected to the air outlet end of the air pump 1000, one end of the air outlet pipe 5 extends out of the cavity, the air inlet pipe 3 is used to draw gas into the air pump 1000 under negative pressure, and the air outlet pipe 5 is used to pump the air in the air pump body 2 of the air pump 1000 into external equipment.

The air pump body 2 is suspended in the shell 4 through the cooperation of the support column 47 and the buffer assembly 1. The vibration generated by the air pump body 2 is absorbed by the buffer assembly 1, and the suspended air pump body 2 makes the air pump body 2 transmit less vibration to the shell 4, and the elastic member 12 in the buffer assembly 1 absorbs the vibration transmitted to the shell 4, thereby realizing shock absorption of the air pump 1000. The shell 4 has a certain noise reduction ability for the noise generated by the operation of the air pump body 2, thereby achieving vibration reduction and noise reduction of the air pump 1000 and improving the use experience of the air pump 1000.
