Detailed Description

The embodiment of the invention provides an air pump capable of quickly replacing a diaphragm, which comprises an air bin 1 and a driving bin 2 welded at the rear end of the air bin 1 as shown in figures 1-7. An air inlet pipe 3 is welded at the top of the front end of the air bin 1, and an air outlet pipe 4 is welded at the top of the rear end of the air bin 1. An air groove is formed in the air bin 1, an air pipe 9 is arranged in the air groove, a piston 91 is welded at the front end of the air pipe 9, and the piston 91 is in sliding fit with the air groove.

As shown in the attached figure 4, the air inlet pipe 3 and the air outlet pipe 4 are both communicated with the air groove, the air inlet pipe 3 is positioned in front of the air groove, and the bottom of the air bin 1 is provided with a bottom plate 5 below the air inlet pipe 3. A positioning ring 6 is arranged in the air inlet pipe 3 in a sliding fit mode, a diaphragm 7 is fixedly installed at the center of the positioning ring 6, a large spring 8 is welded at the bottom of the positioning ring 6, and the lower end of the large spring 8 is in contact with the top of the bottom plate 5. The whole air pump is fixedly provided with a master control interface. The operation of the user is convenient.

The hole that communicates with the inside of trachea 9 is seted up to piston 91 central point, and sliding fit has ball 93 in trachea 9, and well spring 94 has been placed to ball 93 one side of keeping away from piston 91, and trachea 9 pipe shaft has seted up gas pocket 92. The middle spring 94 is always in a compressed state, thereby pushing the ball block 93 to block the hole of the piston 91.

In operation with reference to fig. 3 and 4, the air tube 9 drives the piston 91 to move toward the driving chamber 2. The suction pressure is generated so that the whole positioning ring 6 descends, and the positioning ring 6 brings the diaphragm 7 to descend, thereby drawing air into the intake pipe 3. As the positioning ring 6 is lowered to a position lower than the position where the air groove communicates with the air intake pipe 3, the air sucked into the air intake pipe 3 enters the air groove.

Then, when air enters the air groove, negative pressure between the air groove and the air inlet pipe 3 is lost, and the positioning ring 6 is jacked up by the large spring 8. The positioning ring 6 cooperates with the diaphragm 7 to re-block the inlet tube 3. Air entering the air groove is prevented from leaking. Then, the air tube 9 drives the piston 91 to reset, and the air entering the air groove is pressed into the air tube 9. The ball 93 is affected by the air thrust to compress the middle spring 94. When the ball 93 passes through the air hole 92, the air in the air tube 9 enters the air groove again, so that the drawn air comes from the other side of the piston 91. And the ball 93 loses thrust and resets again.

Then, the air tube 9 moves toward the driving chamber 2 again, and the piston 91 presses air into the air outlet tube 4. The air pipe 9 is moved again, and the operation is repeated to supply the outside air into the air tank. By continuously repeating the process, the purpose of conveying air is achieved.

An annular chamber 62 is formed in the positioning ring 6 and the edge of the diaphragm 7 extends into the chamber 62. The positioning ring 6 is centrally blocked by a diaphragm 7. And the opening of the chamber 62 tightly grips the diaphragm 7.

A conductive sheet 63 is arranged in the chamber 62 at an equal angle around the axis, and one side of the conductive sheet 63 is fixedly bonded with the edge of the diaphragm 7. And a conductive block 64 is arranged on one side of the conductive sheet 63, which is far away from the diaphragm 7, and the conductive block 64 is fixedly adhered to the inner wall of the cavity 62.

A control module 65 is arranged in the positioning ring 6, and the control module 65 is electrically connected with the conductive sheet 63 and the conductive block 64 respectively. The cross section of the chamber 62 is trapezoidal, the upper end of the conducting strip 63 is contacted with the top of the inner wall of the chamber 62, and the lower end of the conducting strip 63 is contacted with the bottom of the inner wall of the chamber 62. The conductive sheet 63 is pulled by the diaphragm 7 to bend, so that the conductive sheet 63 is far away from the conductive block 64, and when the diaphragm 7 loses elasticity, the conductive sheet 63 touches the conductive block 64.

The working principle is as follows: when the diaphragm 7 loses elasticity due to long-term use, the conductive sheet 63 is pulled and then returns to its original shape, and at this time, the conductive sheet 63 and the conductive block 64 touch together. The entire electrical circuit is closed and the control module 65 receives the signal and transmits the information to the master control interface by means of wireless transmission technology.

Sliding grooves are formed in two sides of the inner portion of the bottom plate 5, clamping hooks 51 are arranged in the sliding grooves in a transverse sliding fit mode, grooves 11 are formed in the air bin 1 relative to the clamping hooks 51, and the grooves 11 are communicated with the sliding grooves in a butt joint mode. The hook 51 can extend into the groove 11, the magnet 52 is longitudinally matched in a sliding way, and the steel wire 53 is fixedly bound between the hook 51 and the magnet 52. A small spring 54 is welded between the hook 51 and the inner wall of the sliding chute.

The inner wall of the groove 11 is fixedly adhered with a belt 12, and the belt 12 is fixedly adhered with the end part of the hook 51. The bottom of the inner wall of the groove 11 is welded with a bulge 13, and the clamping hook 51 is clamped by the bulge 13. The bottom plate 5 is clamped with the air chamber 1 through the matching of the hook 51 and the bulge 13. The hook 51 is made of a high-toughness resin material having toughness.

The gas cabin 1 is internally and fixedly provided with electric push rods 10, and the electric push rods 10 correspond to the magnets 52 one by one. The extended end of the electric push rod 10 faces the magnet 52 vertically downwards, and the magnet 101 is fixedly adhered to the extended end of the electric push rod 10. The magnet 101 has a downward magnetic pole N and the magnet 52 has an upward magnetic pole N.

When working with fig. 6, the hook 51 is extended into the groove 11 by the elastic force of the small spring 54, so that the hook 51 is engaged with the groove 11. When the diaphragm 7 loses the elastic information and feeds back the information to the master control interface, the user stops the work of the air pipe 9 by using the master control interface, the air pipe 9 is moved to the original position, and the piston 91 blocks the communication part of the air groove and the air inlet pipe 3.

The electric push rod 10 then extends the driving magnet 101 to press down the positioning ring 6. The positioning ring 6 is lowered while the magnet 101 is close to the magnet 52, and the magnet 52 moves the pulling wire 53 downward under the influence of the magnetic force, thereby drawing the latch 51 into the chute. The belt 12 is stretched at this time, and the positioning ring 6 is removed by ejecting the bottom plate 5 as the electric rod 10 continues to be stretched, thereby replacing the positioning ring 6 and the diaphragm 7 with new ones.

The purpose of the belt 12 is to improve the security between the floor 5 and the air silo 1. The bottom plate is prevented from loosening when the whole device works normally.

In order to improve the sealing effect, a rubber film is wrapped and bonded around the bottom plate 5.

A base 14 is welded outside the gas bin 1, a motor 15 is welded at the bottom of the base 14, and a transmission shaft of the motor 15 is connected with a rubber rod 16. The motor 15 rotates to drive the rubber rod 16 to continuously knock the front end of the air bin 1.

When the positioning ring 6 is replaced, the bottom plate 5 is grasped by hand, and the bottom plate 5 is deviated from the placing opening. The motor 15 is further activated to knock the rubber rod 16, thereby dropping off the dust attached to the inner wall of the air intake pipe 3. The purpose of cleaning ash is realized.

A motor 21 is fixedly arranged in the driving bin 2, a first connecting rod 22 is welded on a transmission shaft of the motor 21, the first connecting rod 22 is hinged to a second connecting rod 23, and the rear end of the air pipe 9 extends into the driving bin 2 and is hinged to the second connecting rod 23.
