Description

Technical Field

[0001] The utility model belongs to the field of ceramic heating elements, and particularly relates to a plasma ceramic heating element for deodorization and sterilization. Background Art

[0002] The high-temperature baked ceramic heating sheet is a new generation of medium and low-temperature heating elements produced by directly printing resistance paste on the green body of AL2O3 alumina ceramic and then baking it at a high temperature of about 1600°C, and then processing the electrodes and leads. It is another replacement product after alloy electric heating wires and PTC heating elements, and is widely used in various fields that require medium and low-temperature heating in daily life, industrial and agricultural technologies, communication, medical treatment, environmental protection, etc.

[0003] The plasma ceramic heating element is a heating device that combines low-temperature plasma technology and ceramic materials. This device uses ceramics as the constituent material of the electrode or reactor because ceramics have good high-temperature resistance, corrosion resistance, and insulation properties, and are suitable as the medium for plasma generation and control. In deodorization and sterilization applications, low-temperature plasma technology generates a large number of active particles, such as electrons, ions, free radicals, etc., through high-voltage discharge. These particles have extremely strong oxidation ability and can decompose harmful gas molecules (such as VOCs) and microorganisms (such as bacteria, viruses) in the air, thereby achieving the effects of air purification and disinfection and sterilization.

[0004] For example, a plasma insecticidal lamp disclosed in the Chinese invention patent with the patent publication number CN202321920752.0 includes a top cover. A hanging rod is fixedly arranged above the top cover, and evenly arranged plasma lamps are fixedly arranged below the top cover. The periphery of the lower edge of the top cover is fixedly arranged with grid rods in a circular array. A bottom ring is fixedly arranged at the lower end of the grid rods. A cleaning mechanism is fixedly arranged at the lower end of the top cover. A conical table is installed on the inner wall of the bottom ring. The rotating cleaning device is used to clean the surface of the conical table. When in use, a higher-frequency light source is used to attract and kill pests, and the insect attracting effect is better. A cleaning mechanism is arranged on the grid rods of the plasma insecticidal lamp. The mobile cleaning device can help the user clean the insects on the grid rods more conveniently and easily. At the same time, the rotating cleaning device can prevent the accumulation of insects inside the plasma insecticidal lamp, reduce pollution generation, and clean the insects on the insecticidal lamp in time, which can ensure the killing efficiency of the plasma insecticidal lamp. However, after the plasma ceramic heating element is used for a long time, dust and sundries will adhere to it, thereby affecting the use of the plasma ceramic heating element and resulting in poor use effects. Therefore, a plasma ceramic heating element for deodorization and sterilization is needed. Summary of the Utility Model

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figures 1 - 3 As shown, a plasma ceramic heater for deodorization and sterilization comprises a top cover 1, a protective sleeve 11 is fixed on the top cover 1, a plasma ceramic heater 12 is fixed on the protective sleeve 11, a motor 13 is fixed on the top cover 1, a circular gear 14 is fixed on the output end of the motor 13, a first gear ring 2 rotatably mounted on the top cover 1 through a bearing is meshed on the circular gear 14, an adjusting component is arranged on the first gear ring 2, a cleaning component is fixed on the adjusting component, the operation of the motor 13 can drive the circular gear 14 to rotate, the circular gear 14 drives the first gear ring 2 to rotate, the rotation of the first gear ring 2 drives the adjusting component to operate, the adjusting component drives the cleaning component to move, and the direction of rotation of the motor 13 is controlled to control whether the cleaning component is close to the ceramic heater or away from the plasma ceramic heater 12, when the motor 13 rotates forward to drive the cleaning component close to the plasma ceramic heater 12, it will drive the cleaning component to rotate continuously, and when the cleaning component is in contact with the plasma ceramic heater 12, it will be driven to rotate by the motor 13 to clean the ceramic heater.

[0019] In this embodiment, the adjusting assembly includes an annular groove formed in the top cover 1. A second toothed ring 5 is fixedly arranged in the annular groove. A spur gear 6 is meshed with the second toothed ring 5. The spur gear 6 is rotatably arranged on the first toothed ring 2 through a bearing. A flat ruler plate 8 is meshed with the spur gear 6. The flat ruler plate 8 is slidably arranged on the first toothed ring 2. A flat groove is formed in the first toothed ring 2, and the flat ruler plate 8 is slidably arranged on the first toothed ring 2 through the flat groove. The cleaning assembly is fixed to the flat ruler plate 8. When the first toothed ring 2 rotates, the first toothed ring 2 drives the spur gear 6 to rotate around the center line of the first toothed ring 2. While the spur gear 6 revolves around the center line of the first toothed ring 2, through meshing with the second toothed ring 5, the spur gear 6 rotates self. The self-rotation of the spur gear 6 drives the flat ruler plate 8 to move. The flat ruler plate 8 drives the cleaning assembly to move horizontally. While the cleaning assembly moves horizontally, it also rotates with the first toothed ring 2. A notch is provided on the flat ruler plate 8. The spur gear 6 drives the flat ruler plate 8 to move towards the plasma ceramic heating body 12. When the cleaning assembly fits against the protective sleeve 11, at the same time the cleaning assembly sticks to the plasma ceramic heating body 12. At this time, the moving position of the flat ruler plate 8 reaches the limit, and the teeth of the spur gear 6 are at the notch of the flat ruler plate 8 and are disengaged from the flat ruler plate 8. Every time the flat ruler plate 8 approaches the spur gear 6, it will be pushed by the spur gear 6 towards the plasma heating body. As the cleaning assembly rotates with the first toothed ring 2, it will clean the surface of the plasma ceramic heating body 12. When the cleaning assembly fits against the plasma ceramic heating body 12, the flat ruler plate 8 and the spur gear 6 are no longer meshed. The cleaning assembly can push the flat ruler plate 8 into contact with the spur gear 6 so that when the spur gear 6 rotates in reverse, it can drive the flat ruler plate 8 to reset.

[0020] In this embodiment, the cleaning assembly includes a sleeve plate 9 fixed to the flat ruler plate 8. A mounting plate 7 is fixed to the sleeve plate 9. A clamping plate 10 is slidably arranged on the mounting plate 7. A bolt 15 for fixing the clamping plate 10 is threadedly connected to the mounting plate 7. A positioning cylinder 16 is fixed to the clamping plate 10. A positioning post 18 is slidably arranged on the positioning cylinder 16. A clamping plate 17 is fixed to the positioning post 18. A spring 19 is sleeved on the outer rings of the positioning cylinder 16 and the positioning post 18. The spring 19 is fixed between the clamping plate 10 and the clamping plate 17. A soft cloth 20 is fixed to the clamping plate 17;

[0021] The cooperation between the positioning cylinder 16 and the positioning post 18 is used to limit the moving direction of the clamping plate 17, to prevent the clamping plate 17 from not being able to keep vertically sticking to the plasma ceramic heating body 12 when rotating with the first toothed ring 2. When the flat tooth plate moves, it drives the sleeve plate 9 to move. The clamping plate 17 drives the soft cloth 20 to first stick to the plasma ceramic heating body 12. At this time, the flat tooth plate is still moving, driving the sleeve plate 9 and the clamping plate 17 to continue approaching the plasma ceramic heating body 12. Then the clamping plate 17 and the soft cloth 20 will squeeze the spring 19 in the reverse direction, so as to tightly stick to the plasma ceramic heating body 12;

[0022] When the template 9 is pressed against the protective sleeve 11, that is, when the spur gear 6 is located at the notch of the spur gear plate, it is at the limit of the movement of the spur gear plate. At this time, the clamping plate 17 and the soft cloth 20 have a certain extrusion on the plasma ceramic heating element 12, forming the first limit protection for the clamping plate 17 to move towards the plasma ceramic heating element 12. However, the spring 19 will continuously push the flat ruler plate 8 towards the spur gear 6 in the reverse direction, and both will be pushed by the spur gear 6 to approach the plasma ceramic heating element 12 again, which may form a large extrusion force on the plasma ceramic heating element 12 in an instant and damage the plasma ceramic heating element 12. However, the template 9 abuts against the protective sleeve 11, playing a limiting role to prevent the clamping plate 17 from continuously extruding the plasma ceramic heating element 12 and avoid crushing the plasma ceramic heating element 12, forming a secondary limit protection. When the clamping plate 17 drives the soft cloth 20 to fit the plasma ceramic heating element 12, the first toothed ring 2 is still rotating, which can drive the soft cloth 20 to clean the plasma ceramic heating element 12. When the motor 13 rotates in the reverse direction, the spur gear 6 no longer pushes the spur gear plate towards the plasma ceramic heating element 12. When the reaction force of the spring 19 pushes the spur gear plate to re-engage with the spur gear 6, the reverse rotation of the spur gear 6 will drive the spur gear plate away from the plasma ceramic heating element 12.

[0023] In this embodiment, the clamping plate 17, the clamping board 10, the placement board 7 and the template 9 are all arc-shaped and share the same center of the circle.

[0024] In this embodiment, a sliding block 21 is fixed on the clamping board 10, a sliding groove 22 is formed on the placement board 7, the sliding block 21 is slidably arranged on the placement board 7 through the sliding groove 22, the bolt 15 passes through the placement board 7 and abuts against the sliding block 21, and the sliding block 21 is slidably arranged on the placement board 7. By using the bolt 15 to abut against the sliding block 21, the sliding block 21 can be prevented from detaching from the placement board 7, thereby preventing the clamping board 10 from horizontally detaching from the placement board 7. The clamping board 10 can be fixed by the bolt 15. At the same time, when the soft cloth 20 needs to be replaced, it is convenient to disassemble and replace the soft cloth 20.

[0025] When the present utility model is in use, by controlling the forward and reverse rotation directions of the motor 13, the forward and reverse movements of the adjusting assembly are controlled, so as to control the cleaning assembly to approach or move away from the plasma ceramic heating element. When the plasma ceramic heating element 12 needs to be cleaned, first turn off the plasma ceramic heating element 12, and then control the motor 13 to rotate forward to drive the cleaning assembly to fit the plasma ceramic heating element and rotate for cleaning. After cleaning, control the motor 13 to rotate in reverse to drive the cleaning assembly away from the plasma ceramic heating element, and then the plasma ceramic heating element 12 is powered on to continue working.

[0026] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
