[0003] There are various types of air compressors on the market. One of the more common types is the piston air compressor, which mainly consists of a body, a ventilation unit, and a motor. By relying on the motor to drive the piston of the ventilation unit to reciprocate, gas pressurization and gas transportation can be achieved, and it is relatively convenient to use.

[0004] However, since most motors in existing piston air compressors are directly mounted on the body, the vibration generated during motor operation will be transmitted to the body, thereby causing the body to vibrate and generate noise. Although some manufacturers install foot pads at the bottom of the body, the actual vibration reduction and noise reduction effects are not obvious, and the user experience is poor.

[0036] Refer to the attached Figure 4 - attached Figure 7 , a motor mounting structure, including a carrier base 1 and a sleeve 2. A plurality of struts 11 are provided on the carrier base 1. A sleeve cavity 20 for mounting a motor 4 is provided inside the sleeve 2. A plurality of support feet 21 made of an elastic material are provided on the outer wall of the sleeve 2. The plurality of support feet 21 are respectively mounted on the plurality of struts 11 one by one, and the motor 4 is suspended.

[0037] Specifically, since the motor 4 is suspended, it does not directly contact the carrier base 1, ensuring that the vibration generated when the motor 4 operates will not be directly transmitted to the carrier base 1. Therefore, the vibration generated when the motor 4 operates can only be transmitted to the carrier base 1 through the plurality of support feet 21 and the plurality of struts 11; and because the plurality of support feet 21 are made of an elastic material and have a certain deformation ability and recovery ability, when impacted, the plurality of support feet 21 will undergo adaptive deformation to effectively buffer the vibration, so that the vibration finally transmitted to the carrier base 1 is reduced, and the possibility of the carrier base 1 generating noise due to vibration is reduced; after the motor 4 stops operating, the plurality of support feet 21 automatically reset for the next buffering use.

[0038] In summary, in the present utility model, multiple struts 11 are designed on the carrier 1 to connect multiple feet 21, so that the sleeve 2 and the motor 4 are suspended, avoiding direct contact between the motor 4 and the carrier 1, reducing the vibration transmission path, and playing a preliminary noise reduction role. The feet 21 made of elastic material can undergo adaptive deformation to buffer the vibration generated during the operation of the motor 4, weakening the final vibration amplitude and noise generated by the carrier 1, achieving vibration reduction and noise reduction, and improving the user experience.

[0039] Refer to the attached Figure 4 - attached Figure 7 , the sleeve 2 is made of elastic material, and the sleeve 2 and multiple feet 21 are integrally formed.

[0040] Specifically, the sleeve 2 made of elastic material has certain vibration reduction ability by itself, which can improve the vibration reduction effect. The integral formation of the sleeve 2 and multiple feet 21 can, firstly, avoid gaps between the sleeve 2 and multiple feet 21, preventing abnormal noises generated by friction at the gaps during the vibration of the motor 4. Secondly, it can improve the overall structural stability, reduce the possibility of fracture at the connection between the sleeve 2 and the bracket, extend the service life of related components. Thirdly, it is convenient for processing and forming, saving the manufacturing cost.

[0041] Among them, there are various types of elastic materials with certain deformation ability and recovery ability, such as silica gel, rubber or polyurethane, etc. Due to the variety of relevant types, the present utility model does not limit this. For the convenience of understanding, silica gel is used to make the sleeve 2 and the feet 21 in this embodiment.

[0042] Refer to the attached Figure 4 - attached Figure 7 , the motor 4 is vertically installed in the sleeve cavity 20, and the output end of the motor 4 extends upward outside the sleeve cavity 20. Multiple feet 21 are circumferentially arrayed on the outer wall of the sleeve 2 and surround the axis of the motor 4.

[0043] Specifically, since the motor 4 is vertically installed, the vibration generated by the rotation of its output shaft will be dispersed to each side of the circumference of the sleeve 2. The design that multiple feet 21 are circumferentially arrayed on the outer wall of the sleeve 2 and surround the axis of the motor 4 can ensure that the vibration generated during the operation of the motor 4 is evenly dispersed to each foot 21, avoiding the tilting phenomenon of the motor 4 caused by uneven force on each foot 21, and improving the installation stability and operation stability of the motor 4.

[0044] Furthermore, the motor 4 is in interference fit with the sleeve cavity 20, so that there is damping between the motor 4 and the sleeve cavity 20. Also, because the motor 4 is vertically installed, under the action of gravity, it is difficult for the motor 4 to disengage from the sleeve cavity 20 upward due to vibration, ensuring that the motor 4 can be stably installed on the sleeve 2. Moreover, compared with the traditional method of using screws for installation and fixation, this design can not only accept materials but also facilitate the installation and disassembly of the motor 4, improving the convenience of use.

[0045] Refer to the appendix Figure 4 - appendix Figure 7 , a vertically designed card hole 110 is provided inside the support column 11, and a notch 111 communicating with the outside is opened on the side wall of the card hole 110; a card shaft 210 is provided on the support leg 21, and the support leg 21 can slide along the notch 111 so that the card shaft 210 can be inserted into or disengaged from the card hole 110, and there is damping between the card shaft 210 and the card hole 110.

[0046] Specifically, the sliding design of the support leg 21 and the notch 111 facilitates the card shaft 210 to enter and exit the card hole 110, thereby facilitating the assembly and disassembly of components such as the motor 4 and the sleeve 2, improving the operation convenience. Also, because there is damping between the card shaft 210 and the card hole 110, the support leg 21 can be stably fixed on the support column 11.

[0047] Refer to the appendix Figure 4 - appendix Figure 7 , there are various ways to make the card shaft 210 and the card hole 110 have damping, and the present utility model does not limit this. For the convenience of understanding, the following two ways are exemplified in this embodiment:

[0048] First, as shown in the appendix Figure 6 , the card shaft 210 and the card hole 110 are in interference fit to have damping.

[0049] Second, as shown in the appendix Figure 5 , the axes of the card shafts 210 of multiple support legs 21 are synchronously offset from the axes of the card holes 110 of multiple support columns 11. When the multiple card shafts 210 are forcibly inserted into the multiple card holes 110, the multiple support legs 21 will undergo adaptive deformation and exert pressure on the card shafts 210, so that the inserted card shafts 210 and the card holes 110 are in a tension state and have damping.

[0050] Specifically, when the motor 4 operates, it will continuously transmit vibration to the support leg 21 and the card shaft 210. If the first method is adopted, after long-term use, the card shaft 210 and the card hole 110 are likely to be worn and loosened; in the second method, the support leg 21 deforms itself to exert pressure on the card shaft 210. Since the support leg 21 is made of elastic material and has a recovery ability, it can continuously exert pressure on the card shaft 210, and under the action of the reaction force, it can also weaken the vibration transmitted by the motor 4, reducing the possibility of the card shaft 210 disengaging from the card hole 110.

[0051] See attached Figure 2 -Attached Figure 6 An end cover 112 is installed at the top opening of the card hole 110, and the end cover 112 surrounds the card shaft 210 and abuts against the card hole 110, and there may be no damping between the card shaft 210 and the card hole 110.

[0052] Specifically, by enclosing and abutting the clamping shaft 210 with the end cover 112 , it is ensured that the clamping shaft 210 will not be separated from the clamping hole 110 regardless of whether there is damping between the clamping shaft 210 and the clamping hole 110 , thereby further improving the installation stability.

[0053] The end can be fixed to the top opening of the clamping hole 110 by means of buckle connection, thread connection, etc. Due to the various methods, this is not limited in the present invention.

[0054] See attached Figure 4 and attached Figure 7 A buffer hole 211 is provided on the side wall of the support leg 21. The design of the buffer hole 211 can increase the deformation capacity of the support leg 21 and provide the support leg 21 with more buffer space to improve the buffer capacity; on the other hand, due to the reduction of material, the overall weight of the support leg 21 can be reduced.

[0055] See attached Figure 4 and attached Figure 7 A plurality of through holes 200 connected to the outside are provided on the side wall of the sleeve cavity 20; the design of the through holes 200 can, on the one hand, connect the sleeve cavity 20 to the outside, facilitating the heat dissipation of the motor 4; on the other hand, due to the reduction of material, the overall weight of the sleeve 2 can be reduced, and the burden on the support legs 21 and the pillars 11 can be reduced.

[0056] See attached Figure 1 -Attached Figure 4 An air compressor includes a body 3, a motor 4, a ventilation unit 5 and a motor mounting structure; the body 3 includes a cover 31 and a base 32 that replaces the carrier 1, the cover 31 is installed on the base 32 and encloses the ventilation unit 5 and the motor mounting structure, and an exhaust terminal 33 is installed on the cover 31; the output end of the motor 4 is connected to the piston drive of the ventilation unit 5, and the ventilation unit 5 is connected to the outside through the exhaust terminal 33.

[0057] Specifically, when in use, the motor 4 drives the piston of the ventilation unit 5 to reciprocate, thereby driving the ventilation unit 5 to compress the gas and deliver the gas to the exhaust end 33; during this process, the vibration generated by the motor 4 will be buffered by the sleeve 2 and each support leg 21, so the air compressor with a built-in motor mounting structure has the effect of shock absorption and noise reduction.

[0058] It should be noted that, since the air compressor is generally the core component of a medical nebulizer, it has the effect of shock absorption and noise reduction during use, which can avoid affecting the patient's rest and improve the user experience. On the other hand, components such as the ventilation unit 5 and the exhaust end 33 are all existing products, so the structure and working principle of the present utility model will not be elaborated in detail.

[0059] Refer to the appendix Figure 1 - appendix Figure 4 , the air compressor further includes a fastening frame 6, the fastening frame 6 is installed on the top of the motor 4, and the ventilation unit 5 is installed on the fastening frame 6; under this design, the vibration generated during the operation of the ventilation unit 5 will also be transmitted to the sleeve 2 and each support leg 21 to further reduce the shock and noise of the air compressor.

[0060] Among them, the fastening frame 6 can be fixed to the motor 4 by means of snap connection, bonding, or directly using screw connection, and the present utility model does not limit this.

[0061] Refer to the appendix Figure 1 - appendix Figure 4 , the motor 4 is a low-voltage DC motor.

[0062] At present, most conventional ventilation units 5 are driven by AC shaded-pole motors (not shown in the figure). The AC shaded-pole motors generate a large amount of heat during operation, so it is necessary to open heat dissipation holes (not shown in the figure) on the body 3, and the sound generated during the operation of the AC shaded-pole motors will be transmitted to the outside through the heat dissipation holes to form noise; while the low-voltage DC motor is an existing product, specifically a DC carbon brush motor or a DC brushless motor, which generates less heat during operation, so there is no need to open additional heat dissipation holes, and the sound generated during its operation cannot be transmitted to the outside, further playing a role in noise reduction.

[0063] It should also be noted that although the embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application.
