[0025] The embodiment of the utility model provides an air pump with a buffering and vibration reduction function.

[0026] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5An air pump with a buffering and vibration reduction function includes a shell 1 and a motor assembly 8 installed inside the shell 1. The inside of the shell 1 is fixedly connected to a fixing frame 2, and a mounting frame 3 is installed on the fixing frame 2. There is a certain movable gap between the fixing frame 2 and the mounting frame 3, so that the mounting frame 3 can move slightly on the fixing frame 2. The outer surface of the shell 1 is inlaid with control buttons, and the control buttons are electrically connected to the control main board inside the device to facilitate the control of the entire device. Heat dissipation holes 11 are opened at both ends of the shell 1, and the heat dissipation holes 11 are provided to facilitate ventilation and heat dissipation inside the shell 1.

[0027] Please refer again Figure 2 、 Figure 3 and Figure 4 , a first buffer mechanism is provided inside the shell 1 for buffering and reducing vibration of the motor assembly 8, the first buffer mechanism includes a connecting spring 4, the motor assembly 8 is fixed on the mounting bracket 3, and the mounting bracket 3 is fixedly connected with a connecting hook 31, and the side of the fixing bracket 2 close to the connecting hook 31 is fixedly connected with a fixing hook 21, and the connecting hook 31 and the fixing hook 21 are connected by a connecting spring 4. The fixing bracket 2 and the mounting bracket 3 are connected together by the provided connecting hook 31, the fixing hook 21 and the connecting spring 4. During operation, the motor assembly 8 slows down the vibration generated by the motor assembly 8 through the provided connecting spring 4, thereby achieving a vibration reduction effect on the motor assembly 8. There are two groups of connecting hooks 31, and the two groups of connecting hooks 31 are distributed at both ends of the mounting bracket 3. There are four connecting springs 4, which are distributed at both ends of the fixing bracket 2. When one or more connecting springs 4 are stretched, the remaining connecting springs 4 will be compressed.

[0028] Please refer again Figure 1 and Figure 5 The bottom of the shell 1 is provided with a second buffer mechanism for buffering and reducing vibration of the entire shell 1. The second buffer mechanism includes a sleeve 7 fixed to the bottom of the shell 1. The bottom of the sleeve 7 is slidably connected to the support seat 5. One end of the support seat 5 is equipped with a shock-absorbing spring 71. The top of the support seat 5 is fixedly connected to the piston plate 6, and the piston plate 6 is slidably connected to the inside of the sleeve 7. By placing the device on a plane, when the device is running, the shell 1 drives the sleeve 7 to vibrate up and down on the outer surface of the support seat 5. When the sleeve 7 descends, it passes through the piston plate 6 to compress the air inside the sleeve 7 to perform preliminary buffering and vibration reduction, and then further buffers and reduces vibration under the action of the elastic force of the shock-absorbing spring 71. The number of shock-absorbing springs 71 is multiple, and multiple shock-absorbing springs 71 are fixed between the piston plate 6 and the inner top wall of the sleeve 7.

[0029] Please refer again Figure 1 and Figure 5A connecting channel 51 and an exhaust channel 52 are provided inside the support seat 5, and the connecting channel 51 is connected to the exhaust channel 52. A through hole connected to one end of the connecting channel 51 is provided on the piston plate 6, and a micro exhaust hole 53 connected to the exhaust channel 52 is provided on the outer surface of the support seat 5. When the sleeve 7 descends, the air inside the sleeve 7 flows into the connecting channel 51 and the exhaust channel 52 through the through hole on the top of the piston plate 6, and is finally discharged through the micro exhaust hole 53. Since the aperture value of the micro exhaust hole 53 is small, the exhaust speed is slow. On the contrary, when the sleeve 7 is rebounded and risen by the shock-absorbing spring 71, the micro exhaust hole 53 is used to inhale. Due to the small aperture value, the intake speed is slowed down, thereby achieving buffering and vibration reduction of the entire device.

[0030] Working principle: The fixing frame 2 and the mounting frame 3 are connected together by connecting hooks 31, fixing hooks 21 and connecting springs 4. The motor assembly 8 on the mounting frame 3 uses the elastic force of the set connecting springs 4 to slow down the vibration generated by the motor assembly 8 during operation. When one or more connecting springs 4 are stretched, the remaining connecting springs 4 will be compressed to achieve buffering and vibration reduction of the motor assembly 8. When the device as a whole vibrates, the shell 1 as a whole vibrates up and down. When the shell 1 descends, the air inside the sleeve 7 flows into the connecting channel 51 and the exhaust channel 52 through the through hole at the top of the piston plate 6, and is finally discharged through the micro exhaust hole 53. Since the aperture value of the micro exhaust hole 53 is small, the exhaust speed is slow, and the shock-absorbing spring 71 will be compressed during the descent to achieve buffering and vibration reduction. Conversely, when the sleeve 7 is rebounded and risen by the shock-absorbing spring 71, the micro exhaust hole 53 is used to inhale. Due to the small aperture value, the intake speed is slowed down, thereby achieving buffering and vibration reduction of the entire device.
