Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, specifically to a medical air-cooled oil-free air compressor. Background Technology

[0002] An air compressor is a device that converts the mechanical energy of a prime mover (usually an electric motor) into the pressure energy of gas; it is a device that generates compressed air. As an important form of energy generation, air compressors are widely used in various aspects of life, especially in industries such as machinery, metallurgy, power, medicine, packaging, chemicals, food, mining, textiles, and transportation, making them a mainstream product for compressed air. Currently, medical air compressors use a fan at the motor output end for air cooling during operation. However, this cooling method, where the motor is located directly connected to the external environment via the cooling fan, makes it difficult for dust and insects to enter the cooling fan area when the compressor is not in use, leading to cleaning difficulties. Therefore, this paper proposes a medical air-cooled oil-free air compressor to solve these problems. Utility Model Content

[0003] To address the problems mentioned in the background art, the technical solution adopted by this utility model is: a medical air-cooled oil-free air compressor, comprising: an air tank, a motor installed at the top of the air tank, a protective ring fixedly installed at the end of the motor by screws, a central seat provided in the middle of the protective ring, a flip-top baffle provided between the outer side of the central seat and the inner side of the protective ring, a rotating rod rotatably connected to the flip-top baffle and the central seat on one side of the flip-top baffle, the rotating rod being fixedly connected to the flip-top body through, a first bevel gear fixedly connected to one end of the rotating rod extending into the interior of the central seat, a second bevel gear provided on one side of the central seat on the first bevel gear, a shaft rotatably connected in the middle of the central seat, and a magnetic reset assembly provided between the shaft and the central seat.

[0004] As a preferred technical solution of this utility model, the magnetic reset assembly includes a first magnet block, an arc-shaped groove, and a second magnet block. The arc-shaped groove is opened on the outer side of the circumference of the shaft, and the second magnet block is fixedly disposed on one side of the upper end of the arc-shaped groove.

[0005] As a preferred embodiment of the present invention, the first magnet block is disposed inside the center seat and is slidably connected to the inside of the arc-shaped groove, and the top of the first magnet block is magnetically connected to the second magnet block.

[0006] As a preferred embodiment of this utility model, one end of the shaft passes through the central seat and is fixedly connected to the second bevel gear, and the second bevel gear meshes with the first bevel gear.

[0007] As a preferred embodiment of this utility model, the number of flap baffles is set to several, and the number of flap baffles is the same as the number of flap bodies.

[0008] As a preferred technical solution of this utility model, a protective strip is provided at one end of the center seat located inside the flip cover baffle, and the end of the protective strip away from the center seat is fixedly connected to the inner side of the protective ring, and the number of protective strips is set to several.

[0009] As a preferred embodiment of this utility model, the motor output end is connected to a cooling fan, and the bottom end of the gas storage tank is provided with a bracket.

[0010] The present invention has the following advantages: By installing an automatically opening and closing flip cover body on the heat dissipation end of the motor, the flip cover body covering the flip cover baffle can be blown up by the wind when the compressor motor is running, so that the motor can be cooled normally by air cooling.

[0011] When the motor stops, the magnetic attraction between the first and second magnets in the magnetic reset assembly causes the flip cover to automatically close onto the flip cover baffle, thus sealing off the cooling fan on the motor and effectively preventing dust or insects from entering when not in use.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] Please refer to the following: Figures 1-8 This utility model discloses a medical air-cooled oil-free air compressor, comprising: an air tank 1, a motor 2 mounted on the top of the air tank 1, a protective ring 3 fixedly mounted on the end of the motor 2 by screws, a central seat 4 in the middle of the protective ring 3, a flip cover baffle 5 between the outer side of the central seat 4 and the inner side of the protective ring 3, a rotating rod 6 rotatably connected to the central seat 4 on one side of the flip cover baffle 5, a flip cover body 7 fixedly connected through the rotating rod 6, a first bevel gear 8 fixedly connected to one end of the rotating rod 6 extending into the interior of the central seat 4, a second bevel gear 9 located on one side of the central seat 4 on the first bevel gear 8, a shaft 10 rotatably connected to the middle of the central seat 4, and a magnetic reset assembly between the shaft 10 and the central seat 4.

[0025] Combination Figure 7 and Figure 8As shown, the magnetic reset assembly includes a first magnet block 11, an arc-shaped groove 12, and a second magnet block 13. The arc-shaped groove 12 is opened on the outer side of the circumference of the shaft 10. The second magnet block 13 is fixedly set on one side of the upper end of the arc-shaped groove 12. The first magnet block 11 is set inside the center seat 4 and is slidably connected to the inside of the arc-shaped groove 12. The first magnet block 11, in conjunction with the arc-shaped groove 12, can not only limit the maximum rotation of the shaft 10, but also, in conjunction with the second magnet block 13, enable the shaft 10 to rotate and reset. The top of the first magnet block 11 is magnetically connected to the second magnet block 13. One end of the shaft 10 passes through the center seat 4 and is fixedly connected to the second bevel gear 9. The second bevel gear 9 meshes with the first bevel gear 8. The number of flip cover baffles 5 is set to a certain number, and the number of flip cover baffles 5 is the same as the number of flip cover bodies 7.

[0026] Combination Figure 4 As shown, the center seat 4 is provided with a protective strip 14 at one end inside the flip cover baffle 5. The protective strip 14 can prevent foreign objects from being inserted into the cooling fan 16 after the flip cover body 7 is opened. The end of the protective strip 14 away from the center seat 4 is fixedly connected to the inner side of the protective ring 3. There are several protective strips 14. The output end of the motor 2 is connected to the cooling fan 16. The bottom end of the gas tank 1 is provided with a bracket 17.

[0027] Specifically, when this utility model is in use, when the motor 2 is running to fill the gas tank 1 with gas, the motor 2 drives the cooling fan 16 to rotate. The air force generated by the cooling fan 16 simultaneously blows multiple flip-top bodies 7, causing the flip-top bodies 7 to drive the rotating rod 6 to rotate. The rotating rod 6 then drives the first bevel gear 8 to rotate, which in turn drives the second bevel gear 9 to rotate. The second bevel gear 9 then drives the shaft 10 to rotate in the center seat 4, causing the first magnet 11 on the shaft 10 to separate from the second magnet 13 on the center seat 4. At this time, the flip-top body 7... The flip cover 5 is lifted up, allowing the cooling fan 16 to dissipate heat from the inside of the motor 2. When the motor 2 stops, the cooling fan 16 stops rotating and does not generate airflow. Then, under the magnetic attraction of the first magnet 11 and the second magnet 13, the shaft 10 is rotated in the opposite direction. The shaft 10, together with the second bevel gear 9, rotates, thereby flipping the flip cover body 7 in the opposite direction. This allows the flip cover body 7 to automatically cover the flip cover 5, thus sealing the cooling fan 16 on the motor 2 and effectively preventing dust or insects from entering when not in use.

[0028] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0029] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
