[0042] Second embodiment:

[0043] Based on the graphene heating dryer provided in the first embodiment of the present application, the second embodiment of the present application proposes another graphene heating dryer. The second embodiment is only a preferred way of the first embodiment, and the implementation of the second embodiment does not affect the separate implementation of the first embodiment.

[0044] The second embodiment of the present application will be further described below in combination with the drawings and embodiments.

[0045] Please refer to Figures 3-5 In the present embodiment, the filter screen 8 is not directly fixed on the air inlet cylinder 6 by bolts, but is slidingly installed in the air inlet cylinder 6. A perforated circular groove box 9 is also slidingly installed in the air inlet cylinder 6, and the perforated circular groove box 9 is located between the negative pressure fan 7 and the filter screen 8. A plurality of stop blocks are fixedly installed on the inner wall of the air inlet cylinder 6, which can limit the installation position of the perforated circular groove box 9. The side of the perforated circular groove box 9 close to the negative pressure fan 7 is in contact with the plurality of stop blocks, and the filter screen 8 is in contact with the perforated circular groove box 9. The perforated circular groove box 9 is filled with filter cotton 10, which is a ceiling cotton and has the advantage of good permeability, with a filtering precision of 2-6 μm, used to intercept small impurities in the air. A fixed block 11 is fixedly installed on the top of the air inlet cylinder 6, a rotating arm 12 is rotatably installed through the fixed block 11, a resisting block 13 is fixedly installed on the lower end of the rotating arm 12, a magnet block 14 is fixedly installed on the side of the filter screen 8 away from the perforated circular groove box 9, the resisting block 13 is in contact with the magnet block 14, and the resisting block 13 resists the filter screen 8 through the magnet block 14, and the filter screen 8 resists the perforated circular groove box 9. The end of the perforated circular groove box 9 close to the negative pressure fan 7 is blocked by a plurality of stop blocks, so that the perforated circular groove box 9 and the filter screen 8 do not sway left and right. The magnet block 14 has an adsorbing effect on the resisting block 13, which can prevent the resisting block 13 from swaying randomly. When it is necessary to clean the filter screen 8 and the filter cotton 10, the rotating arm 12 is rotated to one side, so that the resisting block 13 no longer blocks the filter screen 8. Then the filter screen 8 and the perforated circular groove box 9 can be taken out in turn, and then the impurity cleaning work can be carried out. In order to make the resisting block 13 rotate more smoothly to the magnet block 14, the edge of the side of the resisting block 13 away from the rotating arm 12 is designed as a round corner.

[0046] In the embodiment, in order to avoid the filter cotton 10 from moving in the porous circular groove box 9, a plurality of contact rods are fixedly installed on the side of the filter screen 8 close to the negative pressure fan 7, and a contact circular plate is fixedly installed on the end of each contact rod away from the filter screen 8, and the plurality of contact circular plates are in contact with the filter cotton 10.

[0047] In the embodiment, after the negative pressure fan 7 is started to operate, the external air rushes into the air inlet cylinder 6, and needs to pass through the filter screen 8 and the filter cotton 10 in sequence before entering the heating box 3. The filter screen 8 can intercept the large particles in the air, and the filter cotton 10 can intercept the small particles in the air, so that the air entering the heating chamber 301 is cleaner, which is more conducive to long-term guarantee of the cleanliness of the two graphene heating plates 4. When the filter screen 8 and the filter cotton 10 need to be cleaned, the rotating arm 12 is rotated to the side, so that the contact block 13 is separated from the magnet block 14 and is not in front of the filter screen 8. In this way, the filter screen 8 loses the blockage, and then the filter screen 8 and the porous circular groove box 9 can be taken out from the air inlet cylinder 6 in sequence. After the porous circular groove box 9 is taken out, the filter cotton 10 can be taken out, and then the cleaning work can be performed. By arranging the filter cotton 10, the small particles in the air can be further filtered out, which is conducive to long-term maintenance of the cleanliness of the two graphene heating plates 4, and is conducive to maintaining the heat dissipation efficiency of the two graphene heating plates 4. The filter screen 8 is slidingly installed in the air inlet cylinder 6, the filter cotton 10 is slidingly installed in the air inlet cylinder 6 through the porous circular groove box 9, and the filter screen 8 and the porous circular groove box 9 are limited by the contact block 13, the rotating arm 12 and the fixed block 11, so that they cannot slide out of the air inlet cylinder 6. When the filter screen 8 needs to be cleaned, the contact block 13 is rotated to the side, which has the advantages of facilitating the user to clean the filter screen 8 and the filter cotton 10 and quick operation.

[0049] Based on the graphene heating dryer provided in the second embodiment of the present application, the third embodiment of the present application provides another graphene heating dryer. The third embodiment is only a preferred mode of the second embodiment, and the implementation of the third embodiment does not affect the separate implementation of the second embodiment.

[0050] The third embodiment of the present application will be further described below in combination with the drawings and embodiments.

[0051] Please refer to Figures 6-8In the embodiment, the heating chamber 301 is further provided with a push plate 15 in corrugated shape, one side of the push plate 15 is fixedly provided with a wiping piece 16 in corrugated shape, the wiping piece 16 is cut from a glass fiber cotton piece and has the advantages of high temperature resistance and good corrosion resistance, the wiping piece 16 is used for wiping the surfaces of the two graphene heating plates 4 and removing dust, a plurality of smooth holes are formed in the inner wall of one side of the heating chamber 301, a plurality of guide sliding rods 17 are slidingly installed in the plurality of smooth holes, one end of each of the plurality of guide sliding rods 17 is fixedly connected with the push plate 15, the other end of each of the plurality of guide sliding rods 17 extends out of the heating box 3 and is fixedly provided with the same connecting plate 18, the top of the heating box 3 is fixedly provided with a mounting plate 19, two guide sliding columns 20 are slidingly installed through the mounting plate 19, one end of each of the two guide sliding columns 20 is fixedly connected with the connecting plate 18, a hydraulic cylinder 21 is fixedly installed on the mounting plate 19, an output shaft of the hydraulic cylinder 21 is fixedly connected with the connecting plate 18, a dust passing port is formed in the outer wall of the side of the heating chamber 301 away from the connecting plate 18, the side of the heating box 3 away from the connecting plate 18 is provided with a side sealing plate 22 matched with the dust passing port, and in the embodiment, the side sealing plate 22 is fixedly installed on the heating box 3 by bolts, and in the initial state, the push plate 15 is attached to the inner wall of the side of the heating chamber 301 close to the connecting plate 18.

[0052] In this embodiment, considering that the surfaces of the two graphene heating plates 4 will inevitably be contaminated with dust after long-term use, based on the above reasons, in order not to affect the heat dissipation efficiency of the graphene heating plates 4, the push plate 15, the wiping piece 16 and other components are arranged to regularly clean the two graphene heating plates 4. When regular cleaning is performed, the side sealing plate 22 is first disassembled, and then the output shaft of the hydraulic cylinder 21 is retracted, the hydraulic cylinder 21 drives the connecting plate 18 to gradually approach the heating box 3. The connecting plate 18 drives the push plate 15 to move towards the dust port through the plurality of guide sliding rods 17, the push plate 15 drives the wiping piece 16 to move, so that the two graphene heating plates 4 can be scanned and wiped. When the connecting plate 18 is attached to the heating box 3, the wiping piece 16 moves to the outside of the heating box 3, and then the dust wiped off is pushed out. The related user can place a dust receiving container under the dust port to receive the dust. Then the output shaft of the hydraulic cylinder 21 is extended, so that the push plate 15 and the wiping piece 16 re-enter the heating box 3 and reset. Finally, the side sealing plate 22 is re-fixed. In this embodiment, by arranging the push plate 15, the wiping piece 16, the plurality of guide sliding rods 17, the connecting plate 18, the hydraulic cylinder 21 and the side sealing plate 22, after the side sealing plate 22 is opened, the output shaft of the hydraulic cylinder 21 is retracted, so that the push plate 15 and the wiping piece 16 can be finally pushed out of the heating box 3. During the movement of the wiping piece 16, the surfaces of the two graphene heating plates 4 can be scanned and wiped to remove the dust attached to the surfaces of the graphene heating plates 4, so that the regular cleaning work of the graphene heating plates 4 can be realized, the cleanliness of the graphene heating plates 4 can be maintained, and the heating effect of the graphene heating plates 4 on the air can be further maintained.

[0053] Fourth embodiment:

[0054] Based on the graphene heating dryer provided in the third embodiment of the present application, the fourth embodiment of the present application proposes another graphene heating dryer. The fourth embodiment is only a preferred mode of the third embodiment, and the implementation of the fourth embodiment does not affect the separate implementation of the third embodiment.

[0055] The fourth embodiment of the present application will be further described below in combination with the drawings and embodiments.

[0056] Please refer to Figures 9-13In the embodiment, the side sealing plate 22 is still arranged on one side of the heating box 3, but is no longer directly fixed on the heating box 3. Specifically, a guide cylinder 23 is fixedly installed on the outer wall of the side of the heating box 3 away from the connecting plate 18. The guide cylinder 23 is in communication with the ash passing port. An insertion opening 24 with a size matching that of the side sealing plate 22 is formed in the outer wall of one side of the guide cylinder 23. The side sealing plate 22 penetrates the insertion opening 24 and is in sliding connection with the inner wall of the insertion opening 24. A groove box 25 with a size matching that of the side sealing plate 22 is fixedly installed on the side of the guide cylinder 23 away from the insertion opening 24. An end of the side sealing plate 22 away from the insertion opening 24 extends into the groove box 25. An end plate 26 is fixedly installed on the end of the side sealing plate 22 away from the groove box 25. The end plate 26 is in contact with the guide cylinder 23. Two groups of clamping structures are arranged on the guide cylinder 23 and are used for clamping and fixing the end plate 26. Specifically, any one group of clamping structures comprises a fixed seat 27, a threaded rod 28 and a clamping plate 29. The fixed seat 27 is fixedly installed on the guide cylinder 23. A fixed hole is formed in the fixed seat 27. A nut sleeve is fixedly installed in the fixed hole. The nut sleeve penetrates the fixed seat 27 and is threadedly installed on the fixed seat 27. The clamping plate 29 is rotatably sleeved on the threaded rod 28. The clamping plate 29 is in contact with the end plate 26.

[0057] In this embodiment, when the dust on the two graphene heating plates 4 is cleaned regularly, the two threaded rods 28 are turned counterclockwise in sequence first, and the threaded rods 28 gradually move away from the dust guide cylinder 23 during the turning process, and the clamping plates 29 are driven to move, so that the clamping plates 29 move away from the end plate 26. After the clamping plates 29 are separated from the end plate 26, the lower clamping plates 29 will automatically turn downward under the action of gravity. Then manually turn the upper clamping plates 29 upward, so that the clamping plates 29 lose the blockage, and then pull the end plate 26 away from the dust guide cylinder 23, that is, the side sealing plate 22 is pulled out of the dust guide cylinder 23 and the groove box 25. In this way, the dust port and the dust guide cylinder 23 are not blocked, and then the output shaft of the hydraulic cylinder 21 is retracted to make the wiping piece 16 wipe the two graphene heating plates 4 in a scanning manner. When the connecting plate 18 contacts the heating box 3, the wiping piece 16 runs into the dust guide cylinder 23, and the dust wiped off slides down along the slope on the dust guide cylinder 23 and finally falls below the dust guide cylinder 23. The relevant user can place a dust collecting container at the bottom of the dust guide cylinder 23 to collect the dust. After cleaning, the output shaft of the hydraulic cylinder 21 is extended to reset the push plate 15 and the wiping piece 16, and then the side sealing plate 22 is inserted again, and the two sets of clamping structures are used to fix the end plate 26. In this embodiment, the dust guide cylinder 23 is fixed on the side of the heating box 3 where the dust port is opened, and the side sealing plate 22 is inserted into the dust guide cylinder 23 to block the air. When the two graphene heating plates 4 are cleaned regularly, the side sealing plate 22 is pulled out, and the output shaft of the hydraulic cylinder 21 is retracted to push the wiped dust into the dust guide cylinder 23, and then fall to a lower position along the dust guide cylinder 23. This arrangement allows the user to place the dust collecting container at the bottom of the dust guide cylinder 23 instead of lifting it to the top of the drying box body 1, which is more labor-saving and improves the convenience of regular dust cleaning of the graphene heating plate 4. The two sets of clamping structures are used to clamp and fix the side sealing plate 22, and when the side sealing plate 22 is disassembled, the overall operation amount is reduced, and the operation is simple.

[0058] The above description is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, as described in the specification and drawings of the present application, are also included in the patent protection scope of the present application.
