[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1-4As shown, a toner cartridge cleaning device for a laser printer includes a toner cartridge assembly 1, a cleaning assembly 2 is interspersed inside the toner cartridge assembly 1, the cleaning assembly 2 includes a cleaning column 201, a driving column 203 is slidably arranged inside the cleaning column 201, the outer wall of the driving column 203 is provided with cleaning brushes 206 protruding from the outer wall of the cleaning column 201 and distributed in a circular array, the outer wall of the cleaning column 201 is provided with a rotation groove 207 corresponding to each cleaning brush 206, a connecting rod 208 is connected between the cleaning brush 206 and the cleaning column 201 to keep it diagonally clamped inside the rotating groove 207, and the driving column 203 is driven to keep reciprocating sliding to drive the connecting rod 208 to keep it reciprocatingly diagonally clamped inside the rotating groove 207 to drive the cleaning brush 206 to keep axial rotation.

[0026] The main purpose of the toner cartridge cleaning device for a laser printer is to enable the connecting rod 208 to be diagonally arranged to reciprocate in the rotating groove 207 through the reciprocating motion of the driving column 203, so that the external cleaning brush 206 can rotate axially from the side away from the retaining ring 103 to the side close to the retaining ring 103, thereby cleaning and collecting the residual toner in the toner groove 102; and through the rotating ring 210 set in the middle of the connecting rod 208 and the second sliding groove 209 that is clamped to the rotating ring 210, the connecting rod 208 can extend outward when it rotates, so that the cleaning brush 206 can be pressed against the inner wall of the toner groove 102, and the powder remaining on the inner wall of the toner groove 102 can be cleaned.

[0027] In the technical solution provided by this utility, Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that a first slide groove 202 is provided inside the cleaning column 201, and the driving column 203 is slidably engaged in the first slide groove 202 and can perform reciprocating motion. The outer wall of the end of the cleaning column 201 away from the toner cartridge assembly 1 is also sleeved with a push ring 204, and a push groove 205 is provided on the outer wall of the cleaning column 201 corresponding to the push ring 204, so that the push ring 204 and the driving column 203 can be kept connected. By pushing the push ring 204, the internally connected driving column 203 can slide back and forth, thereby causing the externally connected cleaning brushes 206 to rotate axially, thereby cleaning the inner wall of the toner slot 102.

[0028] Furthermore, a second slide groove 209 is provided inside the rotating groove 207, and a rotating ring 210 is centrally arranged on the connecting rod 208. The rotating ring 210 is slidably engaged in the second slide groove 209. Through the reciprocating motion of the driving column 203, the connecting rod 208 can be reciprocated axially rotated inside the rotating groove 207, so that the connecting rod 208 is reciprocated diagonally, so that the rotating ring 210 moves forward and then backward in the direction close to the cleaning brush 206, so that the cleaning brush 206 moves in the direction of the toner groove 102, thereby squeezing the toner groove 102 with force, so as to clean the powder adhering to the inner wall of the toner groove 102.

[0029] Furthermore, the opposite side ends of the connecting rod 208 are respectively connected to the cleaning brush 206 and the driving column 203, and hinges 211 are provided between the connecting rod 208 and the cleaning brush 206 and the driving column 203. Through the reciprocating motion of the driving column 203 and the movable connection of the hinge 211, the connecting rod 208 can be axially rotated, thereby maintaining a reciprocating diagonal setting inside the rotating groove 207.

[0030] In the technical solution provided by this utility, Figure 1 and Figure 2 It can be seen that the toner cartridge assembly 1 further includes a toner cartridge 101 , and a toner slot 102 is provided inside the toner cartridge 101 for placing toner.

[0031] Furthermore, a retaining ring 103 is provided on the outer wall of the toner cartridge 101, and telescopic retaining blocks 104 distributed in a circular array are provided inside the retaining ring 103. By inserting the cleaning column 201 into the retaining ring 103, the telescopic retaining blocks 104 can be driven to remain contracted, so that the cleaning column 201 can be inserted into the toner slot 102, and each cleaning brush 206 can perform cleaning work in the inner shell of the toner slot 102.

[0032] Working principle: By pushing the cleaning column 201 into the inside of the clamp ring 103, each telescopic clamp block 104 is contracted, so that the cleaning column 201 can be inserted into the inside of the carbon powder tank 102;

[0033] Then, the push ring 204 is pushed to drive the driving column 203 to slide inside the first slide groove 202. The reciprocating motion of the driving column 203 can make the connecting rod 208 reciprocate axially in the rotating groove 207, so that the connecting rod 208 is reciprocated diagonally, so that each cleaning brush 206 connected to the outside is axially rotated, so as to clean the inner wall of the carbon powder groove 102;

[0034] The rotating ring 210 is also moved forward and then backward in the direction close to the cleaning brush 206, so that the cleaning brush 206 moves toward the toner groove 102, thereby squeezing the toner groove 102 with force, thereby cleaning the powder adhering to the inner wall of the toner groove 102.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
