Referring to fig. 8-10, the filtering and cleaning assembly 5 includes a transition joint 501 connected to an air inlet of the air compressing device 3, a piston pipe 502 and a ventilation pipe 503 are fixedly connected to an outer wall of the transition joint 501, a first air storage chamber 504 is fixedly connected to another end of the piston pipe 502 and another end of the ventilation pipe 503, a second air storage chamber 505 is fixedly connected to one side of the first air storage chamber 504, an air outlet of the air compressing device 3 is communicated with the second air storage chamber 505, and stores air in the second air storage chamber 505, when the noise reduction filter 7 is blocked, the first air storage chamber 504 is communicated with the second air storage chamber 505, so that air stored in the second air storage chamber 505 flows through the first air storage chamber 504 and the ventilation pipe 503 and enters the transition joint 501 to be back-blown to the noise reduction filter 7.
Specifically, a communication port 506 is formed between the first gas storage chamber 504 and the second gas storage chamber 505, a piston chamber 507 is formed in the piston pipeline 502, the piston chamber 507 is communicated with a transition joint 501, the inner wall of the piston chamber 507 is connected with a second piston 508 in a sealing sliding manner, the top of the second piston 508 is connected with a spring 509, the other end of the spring 509 is connected with the top of the piston chamber 507, a piston rod 510 is fixedly connected with the bottom of the second piston 508, the piston rod 510 is connected with the piston pipeline 502 in a sliding manner, one end of the piston rod 510 extending to the inside of the first gas storage chamber 504 is fixedly connected with a sealing plug 511 for sealing the communication port 506, the other end of the sealing plug 511 is fixedly connected with an elastic plug 512 for sealing the ventilation pipeline 503, a gas storage channel 513 is formed in one side, away from the communication port 506, of the second gas storage chamber 505, a third one-way valve 514 is arranged in the gas storage channel 513, and the three-way joint 6 is communicated with the gas storage channel 513 through a hose.
When the second piston 508 is in the initial position, the communication port 506 is in a sealed state, the ventilation duct 503 is in an open state, and when the second piston 508 moves toward the transition joint 501, the ventilation duct 503 is preferentially in a sealed state, and the communication port 506 is in an open state.
In actual use, when the air compressor works normally and the first piston 314 moves upwards to compress air, a part of compressed air in the air outlet chamber 306 enters the second air storage chamber 505 for storage through the three-way joint 6, the hose and the air storage channel 513, and the compressed air in the second air storage chamber 505 cannot flow back through the air storage channel 513 due to the third one-way valve 514 arranged in the air storage channel 513.
When the silencing filter 7 is not blocked by impurities in the air, the air normally enters the cylinder 302 through the silencing filter 7, the transition joint 501, the air inlet chamber 305 and the first one-way valve 318 in the process of pumping down the first piston 314, and the pressure in the transition joint 501 and the air inlet chamber 305 cannot be changed.
When the silencing filter 7 is blocked by impurities in the air, at this time, the air flow rate of the air passing through the silencing filter 7 is reduced, during the process of downward movement of the first piston 314 to pump air, due to the reduction of the air flow rate, the negative pressure in the transition joint 501 and the air inlet chamber 305 is increased, at this time, under the effect of the increase of the negative pressure, the second piston 508 in the piston chamber 507 presses the spring 509 to move towards the transition joint 501, the second piston 508 drives the piston rod 510, the sealing plug 511 and the elastic plug 512 to move towards the transition joint 501, so that the ventilation pipeline 503 is preferentially sealed by the elastic plug 512, then the sealing plug 511 releases the sealing of the communication port 506, at this time, the compressed air stored in the second air storage chamber 505 enters the first air storage chamber 504 through the communication port 506, during the upward movement of the first piston 314 to compress the air, the first check valve 318 is in a closed state, the first piston 314 does not pump air through the silencing filter 7 and the transition joint 501, negative pressure is not continuously generated in the transition joint 501, at this time, external air gradually enters into the transition joint 501 through the silencing filter 7 to supplement, so that the pressure in the transition joint 501 is recovered and the negative pressure is eliminated, at this time, the second piston 508 drives the piston rod 510, the sealing plug 511 and the elastic plug 512 to return to the initial positions under the action of the back thrust of the spring 509, the sealing plug 511 seals the communication port 506 preferentially, then the elastic plug 512 releases the sealing of the ventilation pipe 503, compressed air in the first air storage chamber 504 enters into the transition joint 501 through the ventilation pipe 503, at this time, the compressed air in the transition joint 501 is insufficient to open the first check valve 318 due to the fact that the first piston 314 moves the compressed air upwards, at this time, the compressed air in the transition joint 501 can only flow to the silencing filter 7, and the compressed air can back-blow and clean the filter element in the silencing filter 7, so as to prevent impurities in the air from blocking the silencing filter 7.
It should be noted that, the force of blowback can be controlled by installing the ventilating duct 503 with different inner diameters, so as to avoid damaging the silencing filter 7, meanwhile, because the air inlet of the silencing filter 7 faces the direction of the battery compartment 801, the wind generated during air extraction and blowback cleaning can take away a part of heat of the battery pack 403, thereby improving the heat dissipation effect of the battery pack 403, prolonging the service life of the battery pack 403 and increasing the safety of the device.
It should be noted that, in the process of back-blowing cleaning of the sound-deadening filter 7, when the first piston 314 moves the compressed air upward, the compressed air in the transition joint 501 is insufficient to open the first one-way valve 318, the cleaning compressed air cannot enter the cylinder 302, when the first piston 314 moves downward to exhaust air, the communication port 506 and the ventilation duct 503 are always in a sealed state, and the cleaning compressed air cannot enter the transition joint 501, so that in the process of back-blowing cleaning of the blocked sound-deadening filter 7, the normal work of the air compressor is not affected, the on-line cleaning can be achieved, the shutdown cleaning is not needed, and the working efficiency is further improved.
In summary, by the arrangement of the filtering and cleaning assembly 5, on one hand, when the silencing filter 7 is blocked, the silencing filter 7 can be automatically and reversely blown to clean the silencing filter 7 without detaching the silencing filter 7, so that cleaning is more convenient and quick, time is saved, the filter can be restored to normal operation more quickly, and the working efficiency of the device is improved; on the other hand can carry out automatic blowback clearance through the negative pressure that produces after the filter blocks up, need not the user and carries out frequent periodic inspection to the filter according to the difference of environment, can accomplish in time to clear up, avoids the filter to block up, effectively reduces the damaged risk of filter core to increase the life of equipment.
Example two
In the actual use process, when the sound-deadening filter 7 is cleaned by back blowing, a part of compressed gas moves towards the direction of the cylinder 302, and the impact force released by the compressed gas instantaneously cannot be fully applied to the sound-deadening filter 7, so that the cleaning effect is reduced.
Referring to fig. 9-11, a plugging plate 515 for plugging the transitional joint 501 and the ventilation pipeline 503 is hinged in the transitional joint 501, a stop block 516 for blocking excessive opening of the plugging plate 515 is fixedly connected in the transitional joint 501, the ventilation pipeline 503 is plugged when the plugging plate 515 is at an initial position, one end of the transitional joint 501 far away from the silencing filter 7 is plugged when the plugging plate 515 is completely opened, the maximum angle of the plugging plate 515 after opening is an acute angle, and one side of the stop block 516 close to the ventilation pipeline 503 is provided with an inclined surface matched with the inclined surface of the plugging plate 515 after opening by the maximum angle.
In actual use, when the first piston 314 moves downwards to pump air, the blocking plate 515 is in the initial position, and at this time, the blocking plate 515 blocks the ventilation pipeline 503, and air normally enters the cylinder 302 through the silencing filter 7, the transition joint 501, the air inlet chamber 305 and the first check valve 318.
When the back-blowing cleaning is performed on the sound-absorbing filter 7, the spring 509 pushes back the second piston 508 to drive the piston rod 510, the sealing plug 511 and the elastic plug 512 to return to the initial position, the communication port 506 is in a sealing state, the elastic plug 512 releases the sealing on the ventilation pipeline 503, compressed air in the first air storage chamber 504 is instantaneously released through the ventilation pipeline 503, the released compressed air can jack the sealing plate 515 at the initial position, the sealing plate 515 is abutted against the inclined surface of the sealing plate 516 under the limiting effect of the stop block 516 after being jacked up, one end, close to the direction of the cylinder 302, of the transition joint 501 is sealed, and because the maximum angle of the sealing plate 515 after being opened is an acute angle, the instantaneously released compressed air can directly flow to the sound-absorbing filter 7 under the guiding effect of the sealing plate 515, so that the instantaneously released compressed air is completely acted on the sound-absorbing filter 7, and the back-blowing cleaning is performed on the sound-absorbing filter 7, thereby further improving the cleaning effect.
After the compressed air in the first air storage chamber 504 is released after the back-blowing cleaning, the blocking plate 515 in the opened state loses the thrust of the compressed air, and can rotate downwards to return to the initial position after losing the thrust because the blocking plate is in the state of being inclined at an acute angle, so that the normal operation of the air compressor is not affected.
