Referring to fig. 5, as an embodiment of the present invention, lower ends of the two first contacts 23 are both provided with an inwardly concave arc-shaped groove, and upper ends of the two second contacts 24 are both provided with an outwardly convex arc-shaped groove.
The two circular arc-shaped contacts which are matched with each other can obviously improve the contact area between the two contacts, and further improve the electrical conductivity when the first contact 23 and the second contact 24 are contacted.
The working principle is as follows: when the purifier body 1 normally works, external gas can pass through the air inlet 2 and the circular groove 3 and then is pumped into the purifier body 1, then the airflow can push the baffle 10 in the circular groove 3 to move, because the one-way bearing 9 is arranged between the baffle 10 and the nut 8, when the baffle 10 moves rightwards, the one-way bearing 9 and the nut 8 rotate relatively, further the nut 8 is driven to move rightwards along the threaded rod 5, meanwhile, a plurality of elastic air bags 11 can deform, the external gas is pumped into the elastic air bags 11 through the one-way valve 13 at the upper end, the gas is stored to prepare for subsequent use, when the purifier body 1 stops working, the air inlet 2 and the inside of the circular groove 3 can stop air inlet, then the elastic air bags 11 can reset under the self elastic force, then the baffle 10 can drive the one-way bearing 9 and the nut 8 to move leftwards, at this time, the one-way bearing 9 and the nut 8 do not rotate relatively any more, the one-way bearing 9 and the nut 8 are relatively fixed, so the baffle 10 can drive the threaded rod 5 to rotate through the nut 8, and drive the plurality of fixing rods 6 inside the air inlet 2 to rotate, and further brush off the deposited dust at the filter screen through the brush strip 7, further introduce the gas into the cylinder 17 inside the air outlet 14 through the one-way valve 13 at the lower end, after the gas is filtered through the filter cylinder 18 inside the cylinder 17, the gas is discharged through the one-way air outlet valve 20 inside the mounting plate 19, because the gas flow rate of the gas discharged from the purifier body 1 inside the air outlet 14 is large, the pressure at the place with the large flow rate is small according to bernoulli's principle, further drive the gas at the groove air inlet 2 and the brushed dust to enter the inside the filter cylinder 18 through the plurality of first corrugated pipes 16, and the gas can be discharged from the purifier body 1 through the one-way air outlet valve 20 inside the mounting plate 19, dust is collected in the filter cartridge 18, after the dust filtered in the filter cartridge 18 is filtered, the weight of the filter cartridge 18 and the weight of the cylinder 17 are increased, the cylinder 17 moves downwards against the elastic force of the two springs 22 in the sliding groove 26, when enough dust is collected in the filter cartridge 18, the cylinder 17 presses the two first contacts 23 to be respectively contacted with the two second contacts 24, so that a circuit is switched on, an alarm device in the purifier body 1 is started, and a user is reminded timely to clean or replace the filter cartridge 18.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
