Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a multi-directional buffering and shock-absorbing compressor. Background Art

[0002] With the widespread use of compressed air equipment, the vibration generated by the compressor when it is working has become a major defect that affects the user experience, especially when used in quiet scenes, the noise generated by the vibration is particularly obvious.

[0003] In the prior art, most of the vibrations generated by medical nebulizers come from the rotation of the motor. In order to solve the vibrations generated by the rotation of the motor, a common approach is to provide a corresponding shock absorbing device or shock absorbing mechanism, which can, to a certain extent, reduce the vibrations generated by the rotation of the motor.

[0004] For example, the medical shock-absorbing air compressor disclosed in Chinese utility model patent CN204283800U includes a bracket, a compressor pump core, a limiting belt and a spring, wherein there are at least 8 springs, one end of the spring is connected to the compressor pump core, and the other end of the spring is connected to the bracket, and the spring suspends the compressor pump core on the bracket; there are at least 8 limiting belts, one end of the limiting belt is connected to the compressor pump core, and the other end of the limiting belt is connected to the bracket.

[0005] During the actual research and development process, the inventor discovered that although the use of a spring can reduce the vibration generated by the rotation of the motor to a certain extent; however, due to the spring connection, the steel wire will produce high-frequency vibrations, and to a certain extent, the vibrations will still be transmitted to the shell, causing the entire medical nebulizer to vibrate when working, seriously affecting the user's experience; at the same time, the spring connection method is prone to swinging movements, which makes the assembly stability of the motor poor.

[0006] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0007] In view of this, the present invention aims to solve the deficiencies in the prior art, and its main purpose is to provide a compressor with multi-directional buffering and shock absorption, which effectively solves the technical defect in the prior art that the compressor used in the medical nebulizer causes poor user experience due to vibration.

[0009] The beneficial effects of the multi-directional buffering and shock-absorbing compressor provided by the present application are as follows: compared with the prior art, since a rubber connecting strip is provided to replace the spring structure in the prior art, the characteristic of rubber with a large damping ratio can be utilized to further improve the shock-absorbing effect; at the same time, since the rubber connecting strip is provided, the compressor can be installed in a floating manner on a fixed frame, and when the compressor vibrates, it will only vibrate up and down, front and back, or left and right; moreover, the squeezing force of the compressor on the rubber connecting strip is reduced, so that the shock-absorbing effect of the rubber connecting strip can be in the best working state, and when the user actually uses it, the vibration encountered is very small, thereby improving the user experience.

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] Please also read Figures 1 to 3 The multi-directional buffering and shock absorbing compressor provided in the embodiment of the present application is now described. The multi-directional buffering and shock absorbing compressor comprises: a fixing frame 10, a compressor 20 and a plurality of rubber connecting strips 30.

[0034] The compressor 20 includes a base 21, a cylinder sleeve 22 installed on the base 21, a ventilation box 23 installed on the cylinder sleeve 22, and a brushless motor 24 installed on the base 21. The cylinder sleeve 22 is provided with a piston rod, and the brushless motor 24 is used to drive the piston rod to compress the gas in the ventilation box 23; among a plurality of rubber connecting strips 30, one end of each rubber connecting strip 30 is connected to the front side or the rear side of the cylinder sleeve 22, and the other end of each rubber connecting strip 30 is connected to the fixing frame 10, so that the compressor 20 is installed in a floating manner on the fixing frame 10.

[0035] Specifically, since the rubber connecting strip 30 is provided to replace the spring structure in the prior art, the characteristic of rubber with a large damping ratio can be utilized to further improve the shock absorption effect; at the same time, since the rubber connecting strip 30 is provided, the compressor 20 can be installed in a floating manner on the fixing frame 10, and when the compressor 20 vibrates, it will only vibrate up and down, front and back, or left and right; moreover, reducing the squeezing force of the compressor 20 on the rubber connecting strip 30 can make the shock absorption effect of the rubber connecting strip 30 in the best working state, and when the user actually uses it, the vibration encountered is very small, thereby improving the user experience.

[0036] In some embodiments of the present application, the brushless motor 24 is a dual-shaft motor, which includes a body and a rotating shaft disposed on both sides of the body; there are two cylinder sleeves 22, each cylinder sleeve 22 is correspondingly installed on one side of a rotating shaft. The ventilation box 23 is installed on the top of the two cylinder sleeves 22, and the two cylinder sleeves 22 are conductively connected to the ventilation box 23.

[0037] Specifically, there are at least four rubber connecting strips 30, one end of two of the rubber connecting strips 30 is connected to the front side and the rear side of one of the cylinder sleeves 22, and one end of the other two rubber connecting strips 30 is connected to the front side and the rear side of another cylinder sleeve 22; the other ends of the two rubber connecting strips 30 connected to the front side of the cylinder sleeve 22 are connected to the front side of the fixing frame 10, and the other ends of the two rubber connecting strips 30 connected to the rear side of the cylinder sleeve 22 are connected to the rear side of the fixing frame 10.

[0038] In more detail, a first connecting seat 221 is provided on the front and rear sides of the cylinder sleeve 22, and the first connecting seat 221 is provided with a first through hole 222 penetrating the upper and lower surfaces thereof; a first stop portion 31 is provided at the end of the rubber connecting strip 30, and after the rubber connecting strip 30 passes through the first through hole 222 from bottom to top, the first stop portion 31 abuts against the upper surface of the first connecting seat 221.

[0039] Next, the fixing frame 10 includes a bottom plate 11, a front side plate 12 bent upward at the front side of the bottom plate 11, and a rear side plate 13 bent upward at the rear side of the bottom plate 11. The front side plate 12 is provided with a second through hole 121 penetrating through its front and rear surfaces, and the rear side plate 13 is provided with a third through hole 131 penetrating through its front and rear surfaces; when the other end of the rubber connecting strip 30 connected to the front side of the cylinder sleeve 22 passes through the second through hole 121 from back to front, the first stopper 31 abuts against the front surface of the front side plate 12 and bends the rubber connecting strip 30 into an "L" shape; when the other end of the rubber connecting strip 30 connected to the rear side of the cylinder sleeve 22 passes through the third through hole 131 from front to back, the first stopper 31 abuts against the rear surface of the rear side plate 13 and bends the rubber connecting strip 30 into an "L" shape.

[0040] Specifically, by providing a first stopper 31 at the end of the rubber connecting strip 30, the rubber connecting strip 30 can be movably connected to the fixing frame 10 and the cylinder sleeve 22, and the compressor 20 can be installed on the fixing frame 10 in a floating manner by pulling the rubber connecting strip 30 by its own weight, and the compressor 20 is not installed on the fixing frame 10 in a load-bearing manner. Compared with the conventional technology in which the compressor 20 is installed on the fixing frame 10 by means of a rubber block, the compressor 20 is prevented from squeezing the rubber block, thereby improving the buffering and shock-absorbing performance of the rubber connecting strip 30 on the compressor 20. At the same time, since the rubber connecting strip 30 is bent into an "L" shape, it can provide a certain supporting force; with such a structure, even if the compressor 20 vibrates by itself, it will only cause the compressor 20 to vibrate back and forth, up and down, or left and right, and these vibrations can be offset by the rubber connecting strip 30.

[0041] In other embodiments of the present application, the left side of the front side plate 12 and the rear side plate 13 are connected with a first connecting rod body 14, and the right side of the front side plate 12 and the rear side plate 13 are connected with a first connecting rod body 14. The first connecting rod body 14 is provided to improve the overall rigidity of the fixing frame 10. Moreover, both the front side plate 12 and the rear side plate 13 are provided with a step position 15; when assembling the compressor 20, the fixing frame 10 is directly installed into the recess of the outer shell, and the supporting portion of the outer shell is allowed to rest against the step position 15, and the assembly of the compressor 20 can be completed.

[0042] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
