[0022] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] As Figures 1-5 shown, a suction structure of a compressor includes a base 1, a connecting rod 2, an oscillating wheel 3 and a cylinder block 4. A rotating shaft 5 is rotatably connected to the inner side of the base 1, and the outer surface of the rotating shaft 5 is connected to the inner wall of the oscillating wheel 3. The oscillating wheel 3 is supported by the rotating shaft 5 to maintain the stability of the oscillating wheel 3. When the rotating shaft 5 rotates, it drives the oscillating wheel 3 to rotate. When the oscillating wheel 3 rotates, it drives the connecting rod 2 to move up and down.
[0024] One end of the connecting rod 2 is rotatably connected to the inner wall of the oscillating wheel 3. The cylinder block 4 is installed above the base 1. The driving force generated by the up and down movement of the oscillating wheel 3 is transmitted to the rubber plug 7 through the connecting rod 2 to push the rubber plug 7 to move up and down. When the rubber plug 7 moves downward, the gas outside the cylinder block 4 is inhaled. When the rubber plug 7 moves upward, the gas inside the cylinder block 4 is compressed and pushed into the compressor storage tank.
[0025] A support disk 6 is connected to the inner wall of the cylinder block 4. The upper surface of the support disk 6 is connected to the rubber plug 7, and the rubber plug 7 is made of rubber. The appearance of the rubber plug 7 is semicircular and concave in the middle. The rubber plug 7 made of rubber has good ductility and can be repeatedly contracted. The rubber plug 7 is pushed to contract by using the connecting rod 2 as the power, and when the rubber plug 7 contracts, it drives the gas to flow.
[0026] The lower surface of the rubber plug 7 is connected to a tray 8, and the lower surface of the tray 8 is connected to a support seat 9. The inner side of the support seat 9 is rotatably connected to the other end of the connecting rod 2. When the rubber plug 7 moves upward to push the gas inside the cylinder 4 to flow, the gas is compressed by the rubber plug 7. At the same time, the gas generates a reaction force on the rubber plug 7, causing the rubber plug 7 to expand. In order to prevent the rubber plug 7 from over-expanding, a barrier is formed under the rubber plug 7 by the tray 8 to limit the excessive expansion of the rubber plug 7.
[0027] The lower surface of the tray 8 is connected to multiple guide rods 10 at the same time, and the multiple guide rods 10 are located at the four corners of the tray 8. The outer surface of the guide rods 10 is slidably connected to the inner side of the base 1. When the connecting rod 2 pushes the rubber plug 7 to move up and down, in order to prevent the rubber plug 7 from swinging and losing stability, the moving position of the tray 8 is guided by the guide rods 10 to maintain the stability of the rubber plug 7.
[0028] A pressure plate 11 is connected to the upper surface of the rubber stopper 7, and a plurality of bolts 12 are rotatably connected to the inner side of the pressure plate 11, and the plurality of bolts 12 are arranged in a circular array. The bolts 12 penetrate the rubber stopper 7 and are threadedly connected to the support plate 6. The support plate 6 and the pressure plate 11 are tightened and fixed to the rubber stopper 7 by the bolts 12. The stability of the pressure plate 11 is maintained by the bolts 12, and the movement position of the rubber stopper 7 is limited to maintain the stability of the rubber stopper 7.
[0029] The upper surface of the cylinder body 4 is connected with a sleeve 13 and a sleeve 2 14, and the sleeve 13 and the sleeve 2 14 are symmetrical. One side of the sleeve 13 is connected with a connector 15, and the connector 15 is connected to the inside of the sleeve 13. One side of the sleeve 2 14 is connected with a connector 2 16, and the connector 2 16 is connected to the inside of the sleeve 2 14. The connector 15 is connected to an external filter element to filter the gas entering the cylinder body 4 to maintain the cleanliness of the gas. The connector 2 16 is connected to a transmission pipe to transmit the compressed gas to the cylinder body 4. Input into the storage tank, the inner wall of the sliding sleeve 13 is connected with a support ring 17, the inner wall of the support ring 17 is slidably connected with a sliding rod 18, one end of the sliding rod 18 is connected with a sealing gasket 19, and the sealing gasket 19 is made of rubber, and the other end of the sliding rod 18 is connected with a positioning block 20. The stability of the sliding rod 18 is maintained by the support ring 17, and the air inlet of the sliding sleeve 13 is blocked by the sealing gasket 19 to prevent gas leakage, and the positioning block 20 prevents the sliding rod 18 from being separated from the contact with the support ring 17.
[0030] A spring 21 is sleeved on the outside of the slide rod 18, one end of the spring 21 is connected to one side of the positioning block 20, and the other end of the spring 21 is connected to one side of the support ring 17. The elastic driving force provided by the spring 21 pushes the sealing gasket 19 to reset.
[0031] A second support ring 23 is connected to the inner wall of the second sliding sleeve 14. A second sliding rod 24 is slidably connected to the inner wall of the second support ring 23. One end of the second sliding rod 24 is connected to a second sealing pad 25, and the second sealing pad 25 is made of rubber. The other end of the second sliding rod 24 is connected to a second positioning block 26. The stability of the second sliding rod 24 is maintained by the second support ring 23. The air outlet of the second sliding sleeve 14 is blocked by the second sealing pad 25 to prevent gas from flowing back into the cylinder body 4. The second sliding rod 24 is prevented from detaching from contact with the second support ring 23 by the second positioning block 26.
[0032] A second spring 22 is sleeved on the outside of the second sliding rod 24. One end of the second spring 22 is connected to one side of the second support ring 23, and the other end of the second spring 22 is connected to one side of the second sealing pad 25. The second sealing pad 25 is pushed to reset by the elastic driving force provided by the second spring 22.
[0033] It should be noted that during the actual use of this device, first, an external power source drives the rotating shaft 5 to rotate. While the rotating shaft 5 rotates, it drives the pendulum wheel 3 to rotate. The pendulum wheel 3 simultaneously drives the connecting rod 2 to move up and down. The connecting rod 2 pushes the rubber plug 7 to move up and down. When the rubber plug 7 moves downward, it inhales external gas into the cylinder body 4. When the rubber plug 7 moves upward, it compresses the gas inside the cylinder body 4. When the rubber plug 7 moves downward to inhale external gas into the cylinder body 4, at the same time, the first sealing pad 19 moves downward to open the air inlet of the first sliding sleeve 13, and the second sealing pad 25 also moves downward to close the air outlet of the second sliding sleeve 14. When the rubber plug 7 moves upward to compress the gas inside the cylinder body 4, the first sealing pad 19 moves upward to close the air inlet, and the second sealing pad 25 moves upward to open the air outlet, delivering the compressed air into the storage tank.
