[0002] A vacuum pump is a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate a container to obtain a vacuum. In layman's terms, a vacuum pump is a device that uses various methods to improve, generate, and maintain a vacuum in a closed space. According to the working principle of a vacuum pump, it can be basically divided into two types: gas trapping pumps and gas transfer pumps. They are widely used in industries such as metallurgy, chemical industry, food, and electronic coating.

[0003] Vacuum pumps are widely used in many fields such as industrial production. However, most vacuum pumps on the market have obvious drawbacks. High-intensity noise fills the working environment, interfering with workers' normal communication and concentration. Long-term exposure to such a noisy environment can damage workers' hearing and other physical health, causing problems such as tinnitus and hearing loss. Moreover, most vacuum pumps are complicated and cumbersome to install and disassemble, requiring professionals to spend a lot of time and energy, which is not conducive to the rapid replacement, upgrading and maintenance of equipment, and reduces production flexibility and efficiency. Therefore, a vacuum pump with noise reduction function is proposed to solve the above problems. Utility Model Content

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

[0031] Reference Figure 1-6 This utility model provides an embodiment of a vacuum pump with noise reduction function, including a base plate 1, a vacuum pump body 2 fixedly installed on the top of the base plate 1, a protective cover 3 provided on the top of the base plate 1, the bottom of the protective cover 3 contacting the bottom of the base plate 1, fixing blocks 4 fixedly installed on the bottom of both sides of the protective cover 3, and limiting components 5 for limiting the protective cover 3 on both sides of the top of the base plate 1. A noise reduction component 6 for reducing noise in the vacuum pump body 2 is provided inside the protective cover 3. First, the vacuum pump body 2 that needs noise reduction can be fixed on the base plate 1, and then the protective cover 3 can be placed on the base plate 1. At this time, the vacuum pump body 2 will be located inside the protective cover 3. Then, the limiting components 5 limit the protective cover 3, and then the noise reduction component 6 will reduce the noise generated by the vacuum pump body 2 when it is working.

[0032] Reference Figure 1-6The noise reduction component 6 includes sound-absorbing cotton 61. A placement groove 62 is provided on the right side of the protective cover 3, and the sound-absorbing cotton 61 is located inside the placement groove 62. A cover plate 63 is provided on the right side of the protective cover 3, with the left side of the cover plate 63 contacting the right side of the sound-absorbing cotton 61. Through the cooperation of the sound-absorbing cotton 61, the placement groove 62, and the cover plate 63, the sound-absorbing cotton 61 can be placed inside the placement groove 62. Then, the cover plate 63 is pushed to the left, and the left side of the cover plate 63 will contact the right side of the sound-absorbing cotton 61. At this time, the left side of the cover plate 63... It will contact the right side of the protective cover 3, thereby reducing noise of the vacuum pump body 2. The top and bottom of the front and rear sides of the cover plate 63 are fixedly installed with buckles 64, and the top and bottom of the front and rear sides of the protective cover 3 are fixedly installed with mounting sleeves 65. The mounting sleeves 65 are rotatably installed with hooks 66 inside. The hooks 66 and buckles 64 are engaged. Through the cooperation of buckles 64, mounting sleeves 65 and hooks 66, when the hooks 66 are pulled, they can engage with buckles 64, thereby limiting the position of the cover plate 63 and the protective cover 3.

[0033] Reference Figure 1-6 The limiting component 5 includes two sets of connecting rods 51. The top of the connecting rod 51 extends through to the top of the fixing block 4. Two sets of mounting grooves 52 are provided inside the connecting rod 51. A triangular block 53 is slidably installed inside the mounting groove 52. The outer side of the triangular block 53 extends through to the outer side of the connecting rod 51, and the bottom of the triangular block 53 contacts the top of the fixing block 4. Through the cooperation of the connecting rod 51, mounting groove 52, and triangular block 53, when the bottom of the protective cover 3 contacts the top of the base plate 1, the connecting rod 51 will pass through the fixing block 4. When the connecting rod 51 has completely passed through the fixing block 4, the triangular block 53 can be pulled outwards. The triangular block 53 moves outwards and gradually contacts the bottom of the fixing block 4, thereby limiting the protective cover 3. A rectangular block 54 is slidably installed inside the mounting groove 52. The outer side of the rectangular block 54 and the inner side of the triangular block 53 are fixedly installed. The design improves the stability of the triangular block 53 during movement, preventing it from wobbling. A spring 55 is fixedly installed on the inner wall of the mounting groove 52, with the outer end of the spring 55 fixedly installed on the inner side of the rectangular block 54. The spring 55 ensures that the rectangular block 54 and the triangular block 53 are always subjected to its elastic force. When the connecting rod 51 passes through the fixed block 4, the triangular block 53 will move outward due to the elastic force of the spring 55. At this time, the bottom of the triangular block 53 will quickly contact the bottom of the fixed block 4, thus limiting the movement of the protective cover 3. A protective plate 7 is provided on the front side of the protective cover 3. The four corners of the protective plate 7 are installed on the protective cover 3 by bolts and threads. The protective plate 7 allows for easy observation of the working status of the vacuum pump body 2 inside the protective cover 3 and also facilitates convenient maintenance of the vacuum pump body 2.

[0034] Working principle: First, the vacuum pump body 2, which requires noise reduction, is firmly fixed to the base plate 1, providing a foundation for the subsequent installation of components such as the protective cover 3. Then, the protective cover 3 is placed on the base plate 1, so that the vacuum pump body 2 is inside the protective cover 3. During this process, the connecting rod 51 passes through the fixing block 4. When the connecting rod 51 has completely passed through the fixing block 4, because the triangular block 53 is always under the elastic force of the spring 55, it will drive the rectangular block 54 and the triangular block 53 to move outward until the bottom of the triangular block 53 is in close contact with the bottom of the fixing block 4, thus achieving the initial fixation of the protective cover 3. Then, the sound-absorbing cotton 61 is placed inside the placement slot 62 of the protective cover 3. Next, the left side of the cover 63 is attached to the right side of the protective cover 3. Then, the hook 66 is pulled to engage with the buckle 64, thus completing the positioning of the cover 63 and the protective cover 3. When the vacuum pump body 2 is working, it generates noise inside. At this time, the sound-absorbing cotton 61 placed in the placement slot 62 plays its role. The sound-absorbing cotton 61 absorbs and blocks the noise generated by the vacuum pump body 2 through its own sound absorption characteristics, thereby effectively reducing the noise transmitted to the outside world when the vacuum pump body 2 is working and reducing noise pollution to the surrounding environment.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
