Description

Technical Field

[0001] The invention relates to the technical field of air purifiers, and in particular to a purifier capable of quickly and automatically replacing a filter element. Background Art

[0002] Purifiers generally refer to air purifiers, also known as air cleaners, which are products that can absorb, decompose or transform various air pollutants and then discharge high-clean air. They are widely used in households, industries and businesses. Purifiers are divided into active, passive and active-passive hybrid types. However, no matter what working mode, the purification effect depends on the effect of the filter. After working for a long time, the filter will be clogged, reducing the filtering effect. At this time, the filter needs to be replaced manually, which is very inconvenient. Purifiers with quick-replaceable filter cartridges in the prior art are usually only able to facilitate the removal of the filter cartridge, and cannot automatically replace the filter cartridge, thereby maintaining the purifier for long-term uninterrupted use. Summary of the invention

[0003] In response to the above technical problems, the technical solution adopted by the present invention is: a purifier for quickly and automatically replacing a filter element, comprising a filtering device, the filtering device comprising an air inlet, the filtering device being used to inhale and purify the air, the filtering device being provided with a replacing device and a disinfecting device, the replacing device comprising a motor, the replacing device being used to replace the filter element, the disinfecting device comprising a disinfecting chamber, and the disinfecting device being used to disinfect the air.

[0004] Furthermore, the filtering device includes an air intake frame fixedly mounted on the air inlet, a cross rail fixedly mounted on the air intake frame, a mobile frame slidably mounted on the cross rail, an outer sleeve slidably mounted on the air intake frame, the outer sleeve and the mobile frame slidably mounted, a front hose is arranged between the air intake frame and the mobile frame, and a rear hose is arranged between the mobile frame and the disinfection chamber.

[0005] Furthermore, a filter mechanism is provided on the air intake frame, and the filter mechanism includes an upper roller and a lower roller rotatably mounted on the air intake frame, an upper gear is fixedly mounted on the upper roller, a lower gear is fixedly mounted on the lower roller, a belt filter is wound on the upper roller, and the other end of the belt filter is fixedly mounted on the lower roller.

[0006] Furthermore, a plurality of one-way rotating plates are rotatably mounted on the air intake frame, and protruding blocks are fixedly mounted on the one-way rotating plates, so that the one-way rotating plates can only be turned inward around the air intake frame due to the protruding blocks.

[0007] Furthermore, a pressing frame mechanism is provided on the air intake frame, and the pressing frame mechanism includes a moving frame slidably mounted on the air intake frame, a pressing frame is fixedly mounted on the moving frame, the pressing frame and the air intake frame are slidably mounted, a pressing plate is fixedly mounted on the pressing frame, and a frame spring is provided between the pressing frame and the air intake frame.

[0008] When the mobile rack moves toward the disinfection chamber, the rear hose is compressed and the front hose is stretched. At this time, the mobile rack moves toward the disinfection chamber, and the mobile rack and the air inlet rack are in a closed state. As the mobile rack moves, the one-way rotating plate rotates inward to suck gas from the air inlet, and the external gas is filtered through the belt filter and enters the front hose. When the mobile rack stops moving, the one-way rotating plate resets to close the air inlet rack. At this time, the gas is in the front hose and between the mobile rack and the air inlet rack.

[0009] Furthermore, the replacement device includes a motor fixedly mounted on the movable frame, a motor gear is fixedly mounted on the motor shaft of the motor, an upper belt gear and a lower belt gear are rotatably mounted on the movable frame, a docking gear is fixedly mounted on the upper belt gear, an internal gear is fixedly mounted on the lower belt gear, the docking gear is meshed with the motor gear, a vertical transmission belt is wrapped around the lower belt gear and the upper belt gear, an external gear is rotatably mounted on the movable frame, and a horizontal transmission belt is wrapped around the external gear and the internal gear.

[0010] Furthermore, a door opening mechanism is provided on the movable frame, and the door opening mechanism comprises two door panels rotatably mounted on the movable frame, a clamping plate is fixedly mounted on the door panels, and a torsion spring is provided between the door panels and the movable frame.

[0011] When the gas is sucked into the front hose, the mobile frame moves toward the air inlet, the rear hose is stretched, and the front hose is compressed. At this time, since the enclosed space in the front hose is filled with gas, the mobile frame moves toward the air inlet. Under the action of air pressure, the door panel and the card plate will rotate relative to the mobile frame, the torsion spring is twisted, and the gas enters the rear hose from the front hose and finally enters the disinfection chamber.

[0012] In the initial state, the elastic force of the frame spring causes the pressure plate to press the belt filter tightly against the air intake frame. When the belt filter needs to be replaced, the movable frame moves toward the air intake port for a certain distance, and then contacts the movable frame. The movement of the movable frame pushes the movable frame to slide along the air intake frame, driving the pressure frame and the pressure plate to move for a certain distance. The frame spring is compressed, and the pressure plate no longer presses the belt filter tightly. At this time, the upper belt gear is meshed with the upper gear, and the lower belt gear is meshed with the lower gear. At this time, the rotation of the motor drives the motor gear to rotate, thereby driving the docking gear and the upper belt gear The wheel rotates, thereby driving the lower belt gear and the inner gear to rotate through the vertical transmission belt, the upper belt gear drives the upper gear to rotate, the lower belt gear drives the lower gear to engage, the upper gear rotates to make the upper roller release the belt filter, the lower gear rotates to make the lower roller reel up the belt filter, the belt filter that has been used for a period of time is reeled up, and the new belt filter is driven between the air intake rack and the pressure plate, when the mobile rack moves toward the disinfection room, the mobile rack is separated from the mobile frame, the frame spring rebounds, and drives the pressure plate to press the belt filter onto the air intake rack again.

[0013] Furthermore, the disinfection device includes an air outlet fixedly installed on the disinfection chamber, a belt frame fixedly installed on the disinfection chamber, a lower left wheel and a lower right wheel rotatably installed on the belt frame, a driving gear rotatably installed on the belt frame, a docking bevel gear fixedly installed on the driving gear, a large bevel gear rotatably installed on the disinfection chamber, an inner gear fixedly installed on the large bevel gear, an electric cylinder fixedly installed on the disinfection chamber, the electric cylinder and the mobile frame are fixedly installed, a plate changing belt is wrapped around the lower left wheel, the lower right wheel and the driving gear, the docking bevel gear is meshed with the large bevel gear, four ultraviolet lamps are arranged in the disinfection chamber, an activated carbon plate is detachably fixedly installed on the plate changing belt, and the activated carbon plate is slidably installed with the disinfection chamber.

[0014] After the gas enters the disinfection chamber, it is disinfected by an ultraviolet lamp, and then the gas is filtered through an activated carbon plate and discharged from the outlet. The electric cylinder is extended and retracted to drive the mobile frame to slide along the cross rail.

[0015] When the activated carbon plate needs to be replaced, the electric cylinder shrinks to the innermost end, driving the mobile frame to slide toward the disinfection chamber, the inner gear meshes with the outer gear, and the rotation of the inner gear drives the outer gear to rotate through the transverse transmission belt, thereby driving the inner gear and the large bevel gear to rotate, thereby driving the docking bevel gear and the active gear to rotate, thereby driving the plate changing belt to move around the lower left wheel and the lower right wheel, thereby driving the activated carbon plate to slide along the disinfection chamber, so that the activated carbon plate that needs to be replaced leaves the front of the air outlet, and the clean activated carbon plate enters between the disinfection chamber and the air outlet.

[0016] Compared with the prior art, the present invention has the following advantages: (1) The filtering device provided in the present invention can automatically suck the air into the front hose after coarse filtration, and then draw the coarsely filtered air in the front hose into the disinfection box for fine filtration and disinfection, thereby realizing multi-layer filtration and good filtration effect; (2) The replacement device provided in the present invention can quickly replace the belt filter and the activated carbon plate respectively when the movable frame is in different positions, and the replacement is convenient and the degree of automation is high; (3) The one-way rotating plate and the door panel in the filtering device provided in the present invention can only be opened in one direction to prevent gas leakage during the extraction and exhaust process.

[0034] When the mobile frame 104 moves toward the disinfection chamber 301, the rear hose 106 is compressed and the front hose 105 is stretched. At this time, the mobile frame 104 moves toward the disinfection chamber 301, and the mobile frame 104 and the air inlet frame 102 are in a closed state. As the mobile frame 104 moves, the one-way rotating plate 116 rotates inward to inhale the gas from the air inlet 101, and the external gas is filtered through the belt filter 110 and enters the front hose 105. When the mobile frame 104 stops moving, the one-way rotating plate 116 is reset to close the air inlet frame 102. At this time, the gas is located in the front hose 105 and between the mobile frame 104 and the air inlet frame 102.

[0036] like Figure 7 , Figure 8 As shown, a door opening mechanism is provided on the mobile frame 104 , and the door opening mechanism includes two door panels 210 rotatably mounted on the mobile frame 104 , a clamping plate 211 is fixedly mounted on the door panel 210 , and a torsion spring 212 is provided between the door panel 210 and the mobile frame 104 .

[0037] When the gas is sucked into the front hose 105, the movable frame 104 moves toward the air inlet 101, the rear hose 106 is stretched, and the front hose 105 is compressed. At this time, since the enclosed space in the front hose 105 is filled with gas, during the movement of the movable frame 104 toward the air inlet 101, under the action of air pressure, the door panel 210 and the card plate 211 will rotate relative to the movable frame 104, the torsion spring 212 is twisted, and the gas enters the rear hose 106 from the front hose 105, and finally enters the disinfection chamber 301.

[0038] In the initial state, the elastic force of the frame spring 115 causes the pressure plate 118 to press the belt filter 110 tightly against the air intake frame 102. When the belt filter 110 needs to be replaced, the movable frame 104 moves a certain distance toward the air intake port 101, and then the movable frame 104 contacts the movable frame 113. The movement of the movable frame 104 will push the movable frame 113 to slide along the air intake frame 102, driving the pressure frame 114 and the pressure plate 118 to move a certain distance. The frame spring 115 is compressed, and the pressure plate 118 no longer presses the belt filter 110, and the upper belt gear 204 is meshed with the upper gear 109, and the lower belt gear 206 is meshed with the lower gear 112. At this time, the rotation of the motor 201 drives the motor gear 202 to rotate, thereby driving the docking gear 203 and the upper belt gear 20 4 rotates, thereby driving the lower belt gear 206 and the inner gear 207 to rotate through the vertical transmission belt 205, the upper belt gear 204 drives the upper gear 109 to rotate, the lower belt gear 206 drives the lower gear 112 to mesh, the upper gear 109 rotates to make the upper roller 108 release the belt filter 110, the lower gear 112 rotates to make the lower roller 111 roll up the belt filter 110, the belt filter 110 that has been used for a period of time is rolled up, and the new belt filter 110 is driven to between the air inlet frame 102 and the pressing plate 118, when the mobile frame 104 moves toward the disinfection chamber 301, after the mobile frame 104 is separated from the mobile frame 113, the frame spring 115 rebounds, driving the pressing plate 118 to press the belt filter 110 onto the air inlet frame 102 again.

[0039] like Fig. 9 , Fig.10As shown, the disinfection device includes an air outlet 302 fixedly mounted on the disinfection chamber 301, a belt frame 303 fixedly mounted on the disinfection chamber 301, a lower left wheel 305 and a lower right wheel 306 rotatably mounted on the belt frame 303, a driving gear 308 rotatably mounted on the belt frame 303, a docking bevel gear 309 fixedly mounted on the driving gear 308, a large bevel gear 310 rotatably mounted on the disinfection chamber 301, and an inner gear 309 fixedly mounted on the large bevel gear 310. 11. An electric cylinder 312 is fixedly installed on the disinfection chamber 301, and the electric cylinder 312 is fixedly installed on the movable frame 104. A plate changing belt 307 is wound around the lower left wheel 305, the lower right wheel 306 and the driving gear 308. The docking bevel gear 309 is meshed with the large bevel gear 310. Four ultraviolet lamps 313 are arranged in the disinfection chamber 301. An activated carbon plate 304 is detachably fixedly installed on the plate changing belt 307, and the activated carbon plate 304 is slidably installed with the disinfection chamber 301.

[0040] After the gas enters the disinfection chamber 301 , it is disinfected by the ultraviolet lamp 313 , and then the gas is filtered by the activated carbon plate 304 and discharged from the gas outlet 302 . The electric cylinder 312 is extended and retracted to drive the moving frame 104 to slide along the horizontal rail 103 .

[0041] When the activated carbon plate 304 needs to be replaced, the electric cylinder 312 shrinks to the innermost end, driving the movable frame 104 to slide toward the disinfection chamber 301, and the inner gear 311 meshes with the outer gear 209. The inner gear 207 rotates through the transverse transmission belt 208 to drive the outer gear 209 to rotate, thereby driving the inner gear 311 and the large bevel gear 310 to rotate, thereby driving the docking bevel gear 309 and the driving gear 308 to rotate, thereby driving the plate changing belt 307 to move around the lower left wheel 305 and the lower right wheel 306, thereby driving the activated carbon plate 304 to slide along the disinfection chamber 301, so that the activated carbon plate 304 that needs to be replaced leaves the front of the air outlet 302, and the clean activated carbon plate 304 enters between the disinfection chamber 301 and the air outlet 302.

[0042] The working principle of a purifier with fast and automatic filter element replacement disclosed in the present invention is as follows: when the electric cylinder 312 is extended to drive the movable frame 104 to move toward the disinfection chamber 301, the rear hose 106 is compressed and the front hose 105 is stretched. At this time, the movable frame 104 moves toward the disinfection chamber 301, and the movable frame 104 and the air intake frame 102 are in a closed state. As the movable frame 104 moves, the one-way rotating plate 116 rotates inward to inhale gas from the air inlet 101, and the external gas is filtered through the belt filter 110 and enters the front hose 105. When the movable frame 104 stops moving, the one-way rotating plate 116 is reset to close the air intake frame 102. At this time, the gas is located in the front hose 105 and between the movable frame 104 and the air intake frame 102. When the gas is sucked into the front hose 105, the electric cylinder 312 contracts and drives the mobile frame 104 to move toward the air inlet 101, the rear hose 106 is stretched, and the front hose 105 is compressed. At this time, since the enclosed space in the front hose 105 is filled with gas, the door panel 210 and the card plate 211 will rotate relative to the mobile frame 104 under the action of air pressure during the movement of the mobile frame 104 toward the air inlet 101, and the torsion spring 212 is twisted, and the gas enters the rear hose 106 from the front hose 105, and finally enters the disinfection chamber 301. After the gas enters the disinfection chamber 301, the ultraviolet lamp 313 disinfects the gas, and then the gas is filtered by the activated carbon plate 304 and discharged from the air outlet 302. The electric cylinder 312 is extended and retracted to drive the mobile frame 104 to slide along the cross rail 103.

[0043] In the initial state, the elastic force of the frame spring 115 causes the pressure plate 118 to press the belt filter 110 tightly against the air intake frame 102. When the belt filter 110 needs to be replaced, the movable frame 104 moves a certain distance toward the air intake port 101, and then the movable frame 104 contacts the movable frame 113. The movement of the movable frame 104 will push the movable frame 113 to slide along the air intake frame 102, driving the pressure frame 114 and the pressure plate 118 to move a certain distance. The frame spring 115 is compressed, and the pressure plate 118 no longer presses the belt filter 110, and the upper belt gear 204 is meshed with the upper gear 109, and the lower belt gear 206 is meshed with the lower gear 112. At this time, the rotation of the motor 201 drives the motor gear 202 to rotate, thereby driving the docking gear 203 and the upper belt gear 20 4 rotates, thereby driving the lower belt gear 206 and the inner gear 207 to rotate through the vertical transmission belt 205, the upper belt gear 204 drives the upper gear 109 to rotate, the lower belt gear 206 drives the lower gear 112 to mesh, the upper gear 109 rotates to make the upper roller 108 release the belt filter 110, the lower gear 112 rotates to make the lower roller 111 roll up the belt filter 110, the belt filter 110 that has been used for a period of time is rolled up, and the new belt filter 110 is driven to between the air inlet frame 102 and the pressing plate 118, when the mobile frame 104 moves toward the disinfection chamber 301, after the mobile frame 104 is separated from the mobile frame 113, the frame spring 115 rebounds, driving the pressing plate 118 to press the belt filter 110 onto the air inlet frame 102 again. When the activated carbon plate 304 needs to be replaced, the electric cylinder 312 shrinks to the innermost end, driving the movable frame 104 to slide toward the disinfection chamber 301, and the inner gear 311 meshes with the outer gear 209. The inner gear 207 rotates through the transverse transmission belt 208 to drive the outer gear 209 to rotate, thereby driving the inner gear 311 and the large bevel gear 310 to rotate, thereby driving the docking bevel gear 309 and the driving gear 308 to rotate, thereby driving the plate changing belt 307 to move around the lower left wheel 305 and the lower right wheel 306, thereby driving the activated carbon plate 304 to slide along the disinfection chamber 301, so that the activated carbon plate 304 that needs to be replaced leaves the front of the air outlet 302, and the clean activated carbon plate 304 enters between the disinfection chamber 301 and the air outlet 302.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope of the present invention, which should be covered by the protection scope of the present invention.
