[0025] 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.

[0026] like Figure 1-4 As shown, an air sterilizer for easy replacement of filters includes a sterilizer 1, a filter assembly 2 is provided inside the sterilizer 1 for sliding insertion, the filter assembly 2 includes a filter plate 201, cleaning plates 202 are symmetrically provided on the outer walls on both sides of the filter plate 201, baffles 203 that can maintain opening and closing sliding are symmetrically provided inside the cleaning plate 202, a push block 206 extending to the outside is provided on the outer wall of the baffle 203 located on the upper part of the cleaning plate 202, and an extrusion mechanism housed in the cleaning plate 202 is connected to the outer walls of the two baffles 203 away from the push block 206, and the extrusion mechanism is assembled to drive the two baffles 203 to remain closed.

[0027] The main purpose of the air sterilizer that is easy to replace the filter is to provide a push block 206 extending to the outside through the outer wall of the baffle 203 located at the top, so that when the filter plate 201 is taken out upward, the push block 206 will be blocked by the top of the sterilizer 1 to generate a downward force, thereby driving the baffle 203 to move downward to block the filter 214 to prevent dust from being dispersed, and the push block 206 can be axially rotated, so that the baffle 203 can be moved to a suitable position and then the push block 206 can be stored in the storage groove 207 to keep the outside flush, and then it can be detached from the sterilizer 1; the bending block 211 provided at the bottom of the first abutment block 210 is used to abut the second abutment block 212, so that when the baffle 203 located at the top slides down, the bending block 211 can be squeezed to slide down, so that the bending part at the other end slides up, and the baffle 203 located at the bottom is lifted up, so that the two baffles 203 can be closed.

[0028] In the technical solution provided by this utility, Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that a slide groove 204 is provided on the inner wall of the cleaning plate 202 away from the push block 206, and a push groove 205 is also provided on the inner wall of the cleaning plate 202 away from the slide groove 204. The push block 206 is driven to slide and engage in the push groove 205, and is connected to the baffle 203. When the filter plate 201 is taken out upward, the top of the disinfection machine 1 can always abut against the push block 206 so that the push block 206 keeps moving downward relative to the filter plate 201 to drive the baffle 203 to keep sliding along the slide groove 204, thereby closing the filter plate 201.

[0029] Furthermore, a receiving groove 207 is provided at the end of the push groove 205 near the bottom. When the baffle 203 at the top is driven to be closed with the baffle 203 at the bottom, the push block 206 is just located at the receiving groove 207. Since the push block 206 cannot slide down any further, the push block 206 is driven to rotate axially to be received in the receiving groove 207, so that the outer wall of the cleaning plate 202 remains flush, thereby being able to be detached from the disinfection machine 1.

[0030] Furthermore, an extrusion groove 208 symmetrical to the slide groove 204 is provided on the inner wall of the cleaning plate 202 away from the push groove 205, and an extrusion mechanism is provided inside the extrusion groove 208 to be assembled to connect the two baffles 203, so that when the baffle 203 at the top keeps sliding down, the baffle 203 at the bottom can be squeezed to move upward, thereby allowing the two baffles 203 to close.

[0031] Furthermore, the extrusion mechanism specifically includes a first abutment block 210 which is arranged on the outer wall of the baffle 203 located at the top and extends to the inside of the extrusion groove 208, and also includes a second abutment block 212 which is arranged on the outer wall of the baffle 203 located at the bottom and extends to the inside of the extrusion groove 208, and a bending block 211 is abutted against the bottom of the first abutment block 210, and a bending portion is arranged at the end of the bending block 211 away from the first abutment block 210. When the baffle 203 located at the top slides downward, the first abutment block 210 squeezes the bending block 211, thereby causing the bending portion to rise, and by keeping the end of the bending block 211 away from the first abutment block 210 bent and abutting against the bottom of the second abutment block 212, the second abutment block 212 can drive the baffle 203 located at the bottom to rise, thereby allowing the two baffles 203 to close.

[0032] Furthermore, a telescopic column 209 is provided at the end of the extrusion groove 208 close to the baffle 203 to maintain abutment with the first abutment block 210 and the second abutment block 212. When the two baffles 203 are closed, the first abutment block 210 and the second abutment block 212 can abut against the extrusion telescopic column 209 to shrink, and the bending block 211 is always stored in the inside of the extrusion groove 208 to prevent the bending block 211 from being squeezed and popping out.

[0033] Furthermore, a handle 213 is provided on the top of the filter plate 201 to facilitate taking out the filter assembly 2, and a filter screen 214 is provided inside the filter plate 201 to perform filtering work.

[0034] Working principle: First, when the filter screen 214 needs to be replaced, the filter screen assembly 2 is lifted outward by the handle 213. At this time, the push block 206 protruding outward is squeezed by the top of the sterilizer 1, so that when the filter screen assembly 2 moves outward, the push block 206 slides downward relative to the filter screen assembly 2;

[0035] When the push block 206 slides downward relative to the filter assembly 2, the baffle 203 at the top can slide downward synchronously;

[0036] At this time, the first abutting block 210 can be driven to press the bending block 211 downward, so that the bending portion at the other end of the bending block 211 presses the second abutting block 212 upward, thereby driving the baffle plate 203 at the bottom to slide upward, so that the two baffle plates 203 can be closed to collect dust on the filter screen 214;

[0037] When the two baffles 203 are closed, the push block 206 is located exactly inside the storage groove 207. At this time, the push block 206 cannot continue to descend and can only be squeezed and rotated to be stored inside the storage groove 207, so that the outer wall of the filter assembly 2 remains flush, so that the filter assembly 2 can be smoothly taken out and the internal filter 214 can be replaced.

[0038] 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.
