The purpose of storing a certain amount of water in the dust removal box is to reduce dust. When the dust filtered into the dust removal box, it will settle at the bottom of the water.

[0029] (5) After the usage time has passed, the electromagnet is energized. The energized electromagnet generates the same magnetic force as the magnetic slider, and a repulsive force is generated between the two to drive the magnetic slider to drive the movable plate out of the movable cavity and seal the water outlet. The switch valve on the water outlet pipe is opened to allow the dust and part of the water deposited at the bottom of the dust removal box to be discharged from the water outlet pipe. In this way, the dust in the dust removal box can be cleaned out during the operation of the purifier.

[0042] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0043] like Figure 1-7 As shown, the present invention provides a double-inlet fresh air purifier, the purifier comprises: a box body 1, a dust removal mechanism 2 and a base 4;

[0044] The bottom end of the box body 1 is fixedly provided with a base 4 with a hollow structure inside. The dust removal mechanism 2 includes: a dust storage box 201, a filter cloth 202, a reeling shaft 203 and a reeling shaft 204; wherein,

[0045] The dust storage box 201 with the opening facing upward is vertically fixed in the box body 1, and at least two air inlet ends 3 that can be connected to the interior of the dust storage box 201 are fixedly arranged horizontally and at intervals on the side walls of the box body 1. A unwinding shaft 203 and a reeling shaft 204 are rotatably arranged inside the base 4, and a filter cloth 202 is wound on the unwinding shaft 203. The free end of the filter cloth 202 passes through the top of the base 4 and then extends into the box body 1 and fits the side wall of the dust storage box 201 through its opening and covers its opening, and then passes through another corresponding side wall of the dust storage box 201, passes through the bottom end of the box body 1, enters the base 4 and is wound on the reeling shaft 204. An activated carbon adsorption component 12 is fixedly arranged inside the box body 1 above the dust removal mechanism 2, and a negative ion generator 13 is fixedly arranged on its top.

[0046] In the above solution, the activated carbon adsorption assembly 12 includes a mesh box body and activated carbon particles stored in the box body.

[0047] In addition, a blower 15 is provided in each of the air inlet ends 3 to suck external air into the air inlet end 3 and enter the dust removal mechanism 2 through the air inlet end 3 for dust removal.

[0048] In addition, the purifier also includes a driving mechanism 20 for driving the unwinding shaft 203 and the rewinding shaft 204 to rotate, and the driving mechanism 20 includes: a pulley, a belt and a second motor; wherein,

[0049] The same ends of the unwinding shaft 203 and the rewinding shaft 204 are respectively passed through the base 4 and are coaxially fixed with pulleys, and the two pulleys are connected together through the belt transmission. A second motor for driving the unwinding shaft 203 to rotate is horizontally fixed on the base 4, and the output shaft of the second motor is coaxially connected with the unwinding shaft 3 through a coupling. The unwinding shaft 203 and the rewinding shaft 204 can be driven synchronously by the driving mechanism 20, so that when the unwinding shaft 203 unwinds a certain length of the filter cloth 202, the rewinding shaft 204 can rewind the filter cloth 202 of the same length.

[0050] When in use, external air enters the dust removal box 201 through the air inlet end 3, and passes through the filter cloth 202 covering the open opening to filter the dust mixed in the gas through the filter cloth 202 in the dust storage box 201. The filtered gas is further filtered through the activated carbon adsorption component 12 to remove toxic gases and odors in the gas. The gas filtered by the activated carbon adsorption component 12 enters the negative ion generator 13 for filtration again, and finally the gas after multiple filtration is discharged from the exhaust end of the negative ion generator 13 to the external environment.

[0051] After the filter cloth 202 covering the opening of the dust removal box 201 has been used for a period of time, the unwinding shaft 203 and the reeling shaft 204 can be synchronously driven to rotate by the driving mechanism 20, so that the reeling shaft 204 can reel in the unwinding shaft 203 while the unwinding shaft 203 is unwinding, and the used filter cloth 202 covering the opening of the dust removal box 201 is removed and the unused filter cloth 202 is moved to the opening of the dust removal box 201, so that the entire purifier can be used continuously for a long time, thereby increasing its standby time.

[0053] In the above scheme, the filter cloth 202 covering the opening of the dust removal box 201 can be fitted to the edge of the opening through a row of the pressing rollers 5 to prevent gas from escaping from the edge of the opening without being filtered by the filter cloth 202, resulting in poor filtering effect.

[0054] In addition, since the row of pressure rollers 5 are rotatable, the friction between the filter cloth 202 and the filter cloth 202 can be reduced during the movement, thereby avoiding damage to the soft filter cloth 202 and making it convenient to move the filter cloth 202 to replace the filter cloth 202 on the opening of the dust removal box 201.
