[0022] By installing the motor 2 on the outside of the pump body 1, the power output shaft of the motor 2 enters the inner cavity of the pump body 1 and passes through the inner cavity of the movable plate 4. At this time, during the rotation of the motor 2, the movable plate 4 can be driven to reciprocate along the outer wall of the limit rod 3, thereby realizing the push and pull effect on the diaphragm plates 6 on both sides, thereby extracting the liquid.
[0023] In a preferred embodiment, a movable groove is formed on the outer wall of the movable plate 4 , and the outer wall of the diaphragm plate 6 is connected to the inner wall of the pump body 1 .
[0024] By opening a movable groove on the outer wall of the movable plate 4, when the motor 2 rotates, the movable plate 4 can reciprocate along the outer wall of the limit rod 3 under the action of the driving shaft of the outer wall of the motor 2 and the movable groove of the outer wall of the movable plate 4, thereby pushing and pulling the diaphragm plates 6 on both sides.
[0025] In a preferred embodiment, the shape of the outer wall of the closing plate 7 matches the shape and size of the opening of the outer wall of the pump body 1 , and a rubber sealing pad is installed on the outer wall of the closing plate 7 close to the pump body 1 .
[0026] By setting the closing plate 7 on the outer walls on both sides of the pump body 1, when the diaphragm plate 6 and the equipment in the inner cavity of the pump body 1 need to be maintained, the closing plate 7 can be opened at this time, and the limiting nut 9 is rotated to make the limiting nut 9 move along the outer wall of the fixing screw 8, and then the fixing screw 8 is rotated again. At this time, the fixing of the closing plate 7 can be released, so that the closing plate 7 can be opened and the diaphragm plate 6 can be replaced and maintained.
[0027] In a preferred embodiment, the outer wall diameter of the movable cylinder 14 matches the inner wall diameter of the supporting cylinder 13 , and the inner wall diameter of the movable cylinder 14 matches the outer wall diameter of the fixed cylinder 15 .
[0028] By arranging the support cylinder 13 and the movable cylinder 14 at the bottom of the support base 10, under the action of the support cylinder 13 and the movable cylinder 14, when the motor 2 generates vibration during operation, the movable cylinder 14 will move downward along the outer wall of the fixed cylinder 15 under the action of the vibration, so that the outer wall of the movable rod 18 is squeezed by the eardrum 17, and the air in the inner cavity of the movable cylinder 14 and the air in the inner cavity of the fixed cylinder 15 circulate back and forth, thereby realizing shock absorption of the motor 2.
[0029] In a preferred embodiment, the outer wall of the movable rod 18 passes through the top of the fixed tube 15 and the outer wall of the partition 19 to enter the inner cavity of the fixed tube 15 , and a limiting ring is installed on the outer wall of the movable rod 18 .
[0030] By installing a movable rod 18 on the top of the inner cavity of the movable cylinder 14, the movable rod 18 will move with the movement of the movable cylinder 14. During the downward movement of the movable rod 18, the air in the inner cavity of the movable cylinder 14 will pass through the air vent 16 and enter the inner cavity of the fixed cylinder 15, so that the eardrum 17 is tightly attached to the outer wall of the movable rod 18 under the action of air, thereby preventing the movable rod 18 from continuing to move downward.
[0031] In a preferred embodiment, there are four movable cylinders 14 , and the four movable cylinders 14 are respectively installed at the bottom of the supporting base 10 .
[0032] By installing multiple movable cylinders 14 at the bottom of the support base 10, a better shock-absorbing effect on the motor 2 is achieved under the action of the multiple movable cylinders 14 and the support cylinder 13, so that the vibration of the motor 2 during operation can be effectively filtered, thereby ensuring the stability of the motor 2 and the pump body 1 during use.
[0033] Working principle: During the use of the above-mentioned equipment, when the diaphragm plate 6 needs to be replaced, first rotate the limit nut 9 to make the limit nut 9 move along the outer wall of the fixing screw 8 in the direction away from the closing plate 7, and then the outer wall of the limit nut 9 can be separated from the outer wall of the pump body 1. At this time, the closing plate 7 can be rotated to make the outer wall of the closing plate 7 separate from the outer wall of the pump body 1. Then, after the closing plate 7 is opened, the diaphragm plate 6 in the inner cavity of the pump body 1 can be replaced, and vibration will be generated during the operation of the motor 2. At this time, under the action of the support cylinder 13 and the movable cylinder 14, the movable cylinder 14 will move into the inner cavity of the support cylinder 13 under the action of vibration, and during the downward movement of the movable cylinder 14 During the process, the air in the inner cavity of the movable cylinder 14 will pass through the air vent 16 and enter the inner cavity of the fixed cylinder 15, and squeeze the eardrum 17, so that the outer wall of the eardrum 17 fits against the outer wall of the movable rod 18, thereby preventing the movable rod 18 and the movable cylinder 14 from continuing to move downward. At this time, the air pressure in the inner cavity of the fixed cylinder 15 increases under the action of the downward movement of the movable cylinder 14, and then moves upward through the air vent 16, enters the inner cavity of the movable cylinder 14 again, and pushes the movable cylinder 14 upward, so that the movable cylinder 14 can reciprocate up and down, thereby achieving shock absorption of the motor 2 during the reciprocating motion of the movable cylinder 14, thereby ensuring the stability of the motor 2 and the pump body 1 during use.
