[0002] The heater products currently on the market have many shortcomings in terms of air heating efficiency and heating effect. In common convection heaters, the air flows quickly inside the device, resulting in a short contact time between the air and the heating components, insufficient heat absorption, and inability to achieve efficient heating; although some radiant heaters can generate heat quickly, the heat is concentrated in a local area, making it difficult to fully heat the air, and the heat loss during the transfer process is large. In addition, most existing heaters lack effective control measures for the time the air stays heated, making it difficult to flexibly adjust the heating effect according to actual needs, resulting in serious energy waste and poor heating effect. Therefore, it is of great practical significance to develop a heater that can effectively increase the time the air stays heated and significantly improve the heating effect.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See also Figures 1-10 The present invention provides a heater with a ceramic coating heat dissipation structure, including a heater main body 1, and also includes:

[0038] A heating cylinder structure 2, with a plurality of rib structures 3 arranged around the outer circumference of the heating cylinder structure 2, an air guide slot 4 arranged between two adjacent rib structures 3, and a plurality of heating through holes 5 evenly distributed along the height direction on the side walls of the rib structures 3;

[0039] elastic switch valve 6, which is arranged in the convex ridge structure 3 to block or open the heating through hole 5;

[0040] inner and outer sealing cylinder rotating assembly 7, which is wrapped around the inner and outer walls of the heating cylinder structure 2 to rotate, and is used to seal the heating through hole 5 and the air guide slot 4 to stop the internal air circulation and increase the heating time;

[0041] warm air output structure 8, which is arranged on the inner and outer sealing cylinder rotating assembly 7,

[0042] release opening structure 10, which is arranged in the inner and outer sealing cylinder rotating assembly 7 and communicates with the warm air output structure 8, and is used to discharge the air at the corresponding angle from the heating through hole 5 and the air guide slot 4 to the warm air output structure 8;

[0043] central air blowing assembly 9, which is used to send the external air to the inside of the inner and outer sealing cylinder rotating assembly 7, and make the air pass through the plurality of heating through holes 5 and the plurality of air guide slots 4 in the heating cylinder structure 2 to be heated and then discharged from the warm air output structure 8;

[0044] ceramic coating 11, which is coated on the surface of the inner and outer sealing cylinder rotating assembly 7;

[0045] The warmer main body 1 serves as a basic carrier to carry other core components. After the central air blowing assembly 9 is started, the external air is sent into the inner heat insulation cylinder 702 through the central communication pipe 902 by the air inlet hole 105 and the air inlet cavity 103. The convex ridge structure 3, the air guide slot 4 and the heating through hole 5 on the heating cylinder structure 2 increase the air contact area to create conditions for air heating. The inner and outer sealing cylinder rotating assembly 7 rotates under the driving of the driving motor 708. At a non-specific angle, the radial closure 602 of the elastic switch valve 6 closes the heating through hole 5. The air exchanges heat with the heating cylinder structure 2 in the relatively closed space to prolong the heating time. When it rotates to a specific angle, the radial closure 602 moves, the heating through hole 5 is opened, the heated air enters the warm air output structure 8 through the release opening structure 10, and is discharged from the discharge hole 104 through the axial output cylinder 801, the annular air guide groove 802 and the annular air guide grid 803. The ceramic coating 11 is coated on the surface of the inner and outer sealing cylinder rotating assembly 7 to effectively reduce heat loss and at the same time resist high temperature.

[0046] The present invention comprises multiple ridge structures 3 and multiple air guide slots 4 evenly distributed around the circumferential outer wall of the heating tube structure 2. The air guide slots 4 extend from the inner wall of the heating tube structure 2 to the outer wall of the heating tube structure 2. Multiple ridge structures 3 and air guide slots 4 are evenly distributed around the circumferential outer wall of the heating tube structure 2, and the air guide slots 4 extend through the inner and outer walls. This design ensures that air flowing through the heating tube structure 2 evenly contacts the ridge structures 3 and heating holes 5, ensuring that air fully absorbs heat from all directions around the heating tube structure 2, avoiding localized uneven heating. This improves the uniformity and efficiency of air heating and lays the foundation for subsequent deep heating and stable output.

[0047] The elastic switching valve 6 described in the present invention includes a radial guide groove 601 arranged in the middle part of the ridge structure 3, a radial closing member 602 is movably arranged in the radial guide groove 601, a guide shaft 603 is provided at the inner end of the radial closing member 602, a radial guide hole 604 is provided on the heating tube structure 2, the guide shaft 603 is movably inserted into the radial guide hole 604, and an elastic structure 605 is provided between the radial guide groove 601 and the radial closing member 602 for keeping the radial closing member 602 from blocking the corresponding heating through-hole 5; the radial closing member 602 of the elastic switching valve 6 is movable in the radial guide groove 601, the guide shaft 603 is inserted into the radial guide hole 604, and the elastic structure 605 enables the radial closing member 602 to maintain the tendency to block the heating through-hole 5. When the inner and outer sealing cylinder rotating assembly 7 rotates, at the position other than the inner opening 1002, the inner insulation cylinder 702 squeezes the guide shaft 603, so that the radial sealing member 602 seals the heating through hole 5, and the air is continuously heated in the closed space; when the radial sealing member 602 rotates to the position of the inner opening 1002, the inner end of the guide shaft 603 loses the support of the inner insulation cylinder 702 and elastically resets under the action of the elastic structure 605, and the heating through hole 5 opens, thereby realizing the exhaust and circulation control of the air and accurately adjusting the heating time and exhaust timing of the air.

[0048] The heating through hole 5 of the present invention penetrates to the two side walls of a corresponding ridge structure 3 , and the two side walls are connected or blocked by the radial sealing member 602 .

[0049] 5. The heater with a ceramic coating heat dissipation structure according to claim 4 is characterized in that: the inner and outer sealing tube rotating assembly 7 includes an outer insulation tube 701 that is sleeved and rotated on the outside of the heating tube structure 2, an inner insulation tube 702 is provided on the inner side of the heating tube structure 2, the outer side of the ridge structure 3 is provided with an outer arc surface that is in close contact with the inner wall of the outer insulation tube 701, and the inner side of the ridge structure 3 is provided with an inner arc surface that is in close contact with the outer wall of the inner insulation tube 702, and the upper and lower ends of the outer insulation tube 701 and the inner insulation tube 702 are respectively provided with sealing end panels 703; the thrust bearing 705 on the middle support plate 704 is connected to the lower sealing end panel 703 to provide stable support for the inner and outer sealing tube rotating assembly 7. The driving gear 706 at the output end of the drive motor 708 meshes with the driven gear 707 on the lower sealing end panel 703 to transmit the power of the drive motor 708 to the inner and outer sealing tube rotating components 7, driving the outer insulation tube 701 and the inner insulation tube 702 to rotate steadily and smoothly, ensuring the stability and reliability of the rotation process, and thus ensuring the continuity and uniformity of the air heating process.

[0050] The inner and outer sealing cylinder rotating assembly 7 of the present invention also includes an intermediate support plate 704 arranged in the main body 1 of the heater, a thrust bearing 705 is provided on the intermediate support plate 704, the thrust bearing 705 is connected to the sealing end panel 703 below, a driving motor 708 is provided on the intermediate support plate 704, the output end of the driving motor 708 is provided with a driving gear 706, and the sealing end panel 703 below is provided with a driven gear 707, and the driving gear 706 and the driven gear 707 are meshed and driven; the heated air enters the axial output cylinder 801 through the release opening structure 10, and the axial output cylinder 801 guides the air to the annular guide groove 802. The annular guide grid 803 on the annular guide groove 802 combs and disperses the air, making the air flow more uniform and avoiding airflow turbulence and local pressure unevenness. Multiple connecting rods 804 ensure the stable connection between the annular guide groove 802 and the inner and outer sealing cylinder rotating components 7, ensuring that air can be discharged smoothly and stably from the heating output structure 8, providing users with uniform and comfortable heating.

[0051] The heating output structure 8 described in the present invention includes an axial output tube 801 arranged on a side wall of the outer insulation tube 701, and also includes an annular guide groove 802 arranged above the inner and outer sealing tube rotating assembly 7. The upper end of the axial output tube 801 is connected to the annular guide groove 802, and the upper surface of the annular guide groove 802 is provided with an annular guide grid 803 that can improve the uniformity of air flow. A plurality of connecting rods 804 are provided between the annular guide groove 802 and the inner and outer sealing tube rotating assembly 7; the outer opening 1001 and the inner opening 1002 of the release opening structure 10 are located on the same side of the inner and outer sealing tube rotating assembly 7, and the first guide surface 1003 at the inner end of the guide shaft 603 cooperates with the second guide surface 1004 on the edge of one side of the inner opening 1002. When the radial closing member 602 rotates to the position of the inner opening 1002, the guiding action of the first guide surface 1003 and the second guide surface 1004 enables the guide shaft 603 to smoothly break away from the support of the inner insulation tube 702, and the radial closing member 602 is reset under the action of the elastic structure 605, opening the heating through hole 5 and the air guide slot 4; when leaving this position, the inner insulation tube 702 presses the guide shaft 603 back through the second guide surface 1004, closing the channel, thereby achieving precise control of air exhaust and ensuring that only sufficiently heated air can be discharged.

[0052] The release opening structure 10 of the present invention includes an outer opening 1001 provided on the outer insulation cylinder 701, and an inner opening 1002 provided on the inner insulation cylinder 702.

The inner end of the guide shaft 603 is provided with a first guide surface 1003, and the edge of one side of the inner opening 1002 is provided with a second guide surface 1004.

[0053] When the radial sealing member 602 at the corresponding angle moves to the position of the inner opening 1002, the guide shaft 603 at the inner end loses the support rod of the inner heat-insulating cylinder 702 and elastically resets, so that the heating through hole 5 and the air guide slot 4 at the corresponding angle are in a state of mutual communication, facilitating the discharge of the heated air inside.

[0054] When the radial sealing member 602 enters a position range other than the inner opening 1002, the inner heat-insulating cylinder 702 is pressed to seal the corresponding heating holes 5 and the air guide slots 4, thereby increasing the heating time of the internal air.

[0055] The cooperation between the second guide surface 1004 and the first guide surface 1003 enables the guide shaft 603 to smoothly move from the inner opening 1002 to the outer surface of the inner heat-insulating tube 702;

The central communication pipe 902 at the center of the intermediate support plate 704 passes through the staggered through hole 903 at the center of the lower sealing end plate 703 and extends to the inside of the inner heat insulation cylinder 702, so as to accurately transport the air sucked by the air blower 901 to the heating area inside the warmer, provide a stable air source for air heating, and ensure that air can continuously enter the warmer to participate in the heating process.
