[0001] The utility model relates to the technical field of shock-absorbing blowers, in particular to a shock-absorbing screw blower. Background Art
[0002] A screw blower is a blowing device that can compress air internally and then discharge it. Because the screw blower will generate large vibrations when working, the continuous large vibrations will not only accelerate the damage of the screw blower parts, but also cause noise pollution, which is very detrimental to people's work. Therefore, a shock-absorbing screw blower is proposed.
[0003] In response to the above problems, the existing national publication number is: CN217602935U "A shock-absorbing screw blower", which uses methods such as adding springs to provide a shock-absorbing effect for the device. However, in the actual shock-absorbing process, this method cannot consume the energy brought by the vibration, resulting in that during the vibration process, the spring not only cannot provide a good shock-absorbing effect, but may also cause the vibration to intensify, and has the disadvantage of poor shock-absorbing effect. At the same time, this type of equipment can provide a shock-absorbing effect, but cannot provide a good deceleration effect, resulting in the blower still shaking very fast during the vibration process, which in turn causes the blower to be easily damaged by collision, and has the disadvantage of being easily damaged.

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0023] The embodiment of the present application provides a shock-absorbing screw blower, which can realize the use of a shock-absorbing component to provide spring shock absorption while also using continuous buffering of air pressure, and to use the method of releasing heat by high pressure of compressed gas to continuously consume the energy generated during the vibration process, and to use the method of consuming energy to reduce the shaking of the blower, and to prevent the blower from shaking and making noise, and to use a retarding component to continuously slow down the movement speed of the blower during the shaking process, and to prevent the blower from being damaged by collision during the shaking process, thereby improving the protection capability of the blower. The shock-absorbing screw blower is described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments.
[0024] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.
[0025] See also Figure 1-5 middle,
[0026] Example 1
[0027] A shock-absorbing screw blower provided in this embodiment includes: an outer frame 1, an inner frame 2 is arranged inside the outer frame 1, and a blower 201 is arranged inside the inner frame 2; a shock-absorbing component, the shock-absorbing component is arranged between the outer frame 1 and the inner frame 2, and is used to shock the inner frame 2 and the blower 201; and a deceleration component, the deceleration component is arranged in the shock-absorbing component, and is used to slow down the movement speed between the inner frame 2 and the outer frame 1 to reduce the vibration amplitude. During use, the user can use the shock-absorbing component to shock the blower 201 and the inner frame 2 during the rotation process to slow down the vibration of the inner frame 2, and at the same time use the speed limiting component to limit the shaking speed of the inner frame 2 to prevent the inner frame 2 from shaking too frequently and causing damage, thereby improving the shock-absorbing efficiency of the device.
[0028] Among them, during use, a plurality of airtight sleeves 204 arranged on the surface of the inner frame 2 and a shock-absorbing spring 401 arranged between the airtight sleeve 204 and the inner wall of the outer frame 1 are utilized to continuously contract and rebound when vibration occurs between the inner frame 2 and the outer frame 1. During the contraction and rebound process, the vibration frequency between the outer frame 1 and the inner frame 2 is continuously reduced by the deformation of the shock-absorbing spring 401; at the same time, a plurality of shock-absorbing rods 4 arranged on the inner wall of the outer frame 1 are utilized to drive the airtight block 402 at the end of the shock-absorbing rod 4 to continuously slide in the airtight cavity 205 inside the airtight sleeve 204. During the sliding process, the airtight block 402 will squeeze the inside of the airtight cavity 205. The air in the airtight chamber 205 changes back and forth between high pressure and low pressure. When the air becomes high pressure air, heat is generated. The kinetic energy is converted into thermal energy, and the heat is used to continuously consume energy during the continuous contraction process. In this way, the sliding between the airtight block 402 and the airtight sleeve 204 is reduced, so that the airtight block 402 and the airtight sleeve 204 can be continuously slowed down, further preventing the vibration between the outer frame 1 and the inner frame 2. The above two methods of pneumatic and spring braking are used to simultaneously reduce the vibration of the blower 201 during use, so as to prevent the device from vibrating too much, generating a lot of noise and damaging the device.
[0029] During use, the limit groove 206 opened on the inner wall of the airtight chamber 205 is continuously slidably connected with the limit blocks 403 on both sides of the airtight block 402, and the limit groove 206 can be used to continuously limit the limit block 403, so that the limit block 403 and the airtight block 402 cannot be separated from the airtight sleeve 204 for use, thereby preventing the airtight block 402 from being stuck inside the airtight sleeve 204 and unable to slide.
[0030] During use, when the air-tight block 402 is continuously sliding, air may pass through the gap between the shock-absorbing rod 4 and the air-tight sleeve 204, causing leakage of the internal pressurized air. At this time, the rubber pad 404 on the inner wall of the air-tight block 402 close to the shock-absorbing rod 4 can be used to seal the gap between the inner wall of the air-tight sleeve 204 and the air-tight block 402 during the sliding process, thereby preventing air leakage from causing unstable pressurization and causing the shock-absorbing effect of the device to deteriorate, thereby improving the practicability of the device.
[0031] During use, when the user needs to fix the device in the use position, multiple fixing plates 101 are set on the surface of the outer frame 1, and two fixing openings 102 with different directions are opened on the surface of the fixing plate 101 to fix the fixing plate 101 and the outer frame 1 on the installation surface. The "L"-shaped structure is used to cooperate with the two fixing openings 102, so that the outer frame 1 can cooperate with the surfaces of various environments, thereby improving the practicality of the device.
[0032] During use, an anti-slip groove 301 is provided at the bottom of the deceleration plug plate 3, and an anti-slip block 304 is provided at the top of the rotating plate 302, and the anti-slip groove 301 is slidably connected to the anti-slip block 304. During use, the sliding connection between the anti-slip block 304 and the anti-slip groove 301 is utilized to allow the deceleration plug plate 3 and the rotating plate 302 to rotate, and ensure that the rotating plate 302 will not fall off the deceleration plug plate 3.
[0033] Example 2
[0034] On the basis of Example 1, when the mutual sliding connection between the outer frame 1 and the inner frame 2 allows the multiple deceleration plug plates 3 arranged on the inner wall of the outer frame 1 to be continuously slidably connected with the deceleration sleeve 202 on the surface of the inner frame 2, during the sliding connection process, the rotating plate 302 at the bottom of the deceleration plug plate 3 will also continuously slide between the deceleration sleeve 202, and at this time, the two deceleration blocks 303 on the surface of the rotating plate 302 will be rotationally connected with the deceleration thread 203 provided on the inner wall of the deceleration sleeve 202, and under the action of the deceleration thread 203, the deceleration block 303 will drive the rotating plate 302 to rotate continuously, and at the same time, during the rotation process, only when the rotating plate 302 rotates a certain number of times can it drive the deceleration plug plate 3 to move in the deceleration sleeve 202, so that the rotation speed of the rotating plate 302 controls the moving speed between the outer frame 1 and the inner frame 2, and prevents the outer frame 1 and the inner frame 2 from shaking too fast, causing vibration and excessive noise.
[0035] During use, the deceleration block 303 is arranged in a cylindrical structure, which has the effect of smaller contact surface and friction force, and the deceleration block 303 is made of white ceramic material, which has the effect of smaller friction coefficient, and can prevent the deceleration block 303 and the deceleration thread 203 from getting stuck with each other.
