Description

Technical Field

[0001] This utility model relates to the field of ceramic electric heater technology, specifically to a ceramic electric heater base with overheat protection. Background Technology

[0002] The ceramic electric heater base is the core supporting structure of the ceramic electric heater. Made of ceramic material, it boasts excellent insulation and heat resistance, providing a stable support for the heating element, efficiently conducting heat, and ensuring stable operation of the heater.

[0003] Although traditional ceramic electric heater base circuit systems are equipped with overheat protection mechanisms, which can quickly and automatically cut off power when the operating temperature exceeds the safety threshold to prevent equipment damage or safety accidents caused by overheating, heat dissipation still relies on natural cooling, which is slow and not only increases the risk of failure but also shortens the service life of the equipment. Therefore, a ceramic electric heater base with overheat protection is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the problem that traditional ceramic electric heater bases using natural cooling methods have low heat dissipation efficiency. This invention provides a ceramic electric heater base with overheat protection.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A ceramic electric heater base with overheat protection includes a disc, in which the ceramic electric heater base is fixedly installed. An electrical box is fixedly installed at the bottom of the disc. Two sets of symmetrically distributed heat dissipation holes are provided on the side wall of the ceramic electric heater base. Each set of heat dissipation holes consists of several heat dissipation holes evenly opened on the side wall of the ceramic electric heater base. A flow guiding component for guiding airflow is provided inside the disc. A transmission component for driving the flow guiding component to rotate is provided inside the disc. A cooling component for heat dissipation is provided on the side wall of the disc.

[0007] Furthermore, the flow guiding component includes an arc-shaped plate, and two symmetrically distributed arc-shaped plates are arranged inside the disk. An arc-shaped frame is fixedly installed at the middle of the two adjacent ends of the two arc-shaped plates, and the two arc-shaped plates and the two arc-shaped frames together form a ring structure.

[0008] Furthermore, the flow guiding component also includes an annular groove. An annular groove is formed on the side wall of the ceramic electric heater base. A circular ring is movably installed inside the annular groove. The circular ring is fixedly installed inside the annular structure composed of two arc-shaped plates and two arc-shaped frames.

[0009] Furthermore, the transmission assembly includes an annular groove II, an annular groove II is formed on the inner bottom surface of the disc, a circular groove is formed on the inner bottom surface of the disc, a gear ring is fixedly installed at the bottom of the annular structure composed of two arc plates and two arc frames, a servo motor is fixedly installed inside the electrical box, and a gear is fixedly connected to the output end of the servo motor extending into the inside of the disc, with the gear and the gear ring meshing together.

[0010] Furthermore, the cooling assembly includes arc-shaped holes, and two arc-shaped holes are opened on the side wall of the disc. Air guide boxes are fixedly installed on the side wall of the disc corresponding to the two arc-shaped holes. Two exhaust fans are embedded in the right air guide box, and two exhaust fans are embedded in the left arc-shaped hole.

[0011] Furthermore, the bottom of each air guide box is on the same plane as the bottom of the electrical box to facilitate stable placement, the horizontal port of each air guide box is adapted to the adjacent arc-shaped hole, and each arc-shaped hole is adapted to the arc-shaped frame.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention controls the rotation of the airflow guiding component through the transmission component, which can expose or block the two sets of heat dissipation holes. When the heat dissipation holes are blocked, it can prevent external dust from entering. When the heat dissipation holes are exposed, the cooling component can be activated simultaneously to exhaust hot air to the outside and then inject cold air into the equipment, thereby accelerating the cooling of the ceramic electric heater base, improving the cooling effect, reducing the risk of failure of the ceramic electric heater base due to overheating, and ensuring the service life of the equipment.

Therefore, they should not be construed as limitations on this utility model.

[0024] like Figure 1-5As shown, a ceramic electric heater base with overheat protection includes a disc 1. A ceramic electric heater base 2 is fixedly installed inside the disc 1. An electrical box 3 is fixedly installed at the bottom of the disc 1 (in this technical solution, the electrical box 3 is mainly used to install various electrical components required to support the operation of the ceramic electric heater base 2 and the circuit overheat protection system; since it is prior art, it is not described in detail in this technical solution). Two sets of symmetrically distributed heat dissipation holes 4 are provided on the side wall of the ceramic electric heater base 2. Each set of heat dissipation holes 4 consists of several heat dissipation holes 4 evenly opened on the side wall of the ceramic electric heater base 2. A flow guiding component 5 for guiding airflow is provided inside the disc 1; Figure 1-4 As shown, specifically, the flow guiding component 5 includes an arc plate 501. Two symmetrically distributed arc plates 501 are arranged inside the disc 1. An arc frame 502 is fixedly installed at the middle of the two adjacent ends of the two arc plates 501. The two arc plates 501 and the two arc frames 502 together form an annular structure. An annular groove 503 is opened on the side wall of the ceramic electric heater base 2. A circular ring 504 is movably installed inside the annular groove 503. The circular ring 504 is fixedly installed inside the annular structure formed by the two arc plates 501 and the two arc frames 502.

[0025] More specifically, the annular structure formed by the two arc-shaped plates 501 and the two arc-shaped frames 502 can be rotated at the required angle. If the two arc-shaped plates 501 block the two sets of heat dissipation holes 4, it can prevent external dust from entering the interior of the ceramic electric heater base 2. If the two arc-shaped frames 502 are rotated to the position of the two sets of heat dissipation holes 4, it can facilitate the discharge of hot air inside the ceramic electric heater base 2 from the heat dissipation holes 4, and it can also facilitate the entry of external cold air into the interior of the ceramic electric heater base 2 for cooling.

[0026] The interior of the disk 1 is equipped with a transmission component 6 for driving the rotation of the flow guiding component 5, such as... Figure 1-5 As shown, specifically, the transmission component 6 includes an annular groove 601, an annular groove 601 is formed on the inner bottom surface of the disc 1, a circular groove 602 is formed on the inner bottom surface of the disc 1, a gear ring 603 is fixedly installed at the bottom of the annular structure composed of two arc plates 501 and two arc frames 502, a servo motor 605 is fixedly installed inside the electrical box 3, and a gear 604 is fixedly connected to the output end of the servo motor 605 inside the disc 1, and the gear 604 and the gear ring 603 are meshed together.

[0027] More specifically, if the servo motor 605 is started, it can drive the gear 604 to reciprocate at a preset angle and speed. The reciprocating rotation of the gear 604 can drive the gear ring 603 to reciprocate. The reciprocating rotation of the gear ring 603 can drive the ring structure composed of two arc plates 501 and two arc frames 502 to reciprocate.

[0028] The side wall of the disk 1 is provided with a cooling component 7 for heat dissipation, such as... Figure 1 , 2 As shown in Figure 5, specifically, the cooling assembly 7 includes arc-shaped holes 701. Two arc-shaped holes 701 are opened on the side wall of the disc 1. Air guide boxes 702 are fixedly installed on the side wall of the disc 1 corresponding to the positions of the two arc-shaped holes 701. Two exhaust fans 703 are embedded in the right air guide box 702, and two exhaust fans 704 are embedded in the left arc-shaped hole 701. The bottom of each air guide box 702 is on the same plane as the bottom of the electrical box 3 for stable placement. The horizontal port of each air guide box 702 is adapted to the adjacent arc-shaped hole 701, and each arc-shaped hole 701 is adapted to the arc-shaped frame 502.

[0029] More specifically, when the supply fan 704 and the exhaust fan 703 are started, the supply fan 704 can draw in hot air through the corresponding arc-shaped hole 701, arc-shaped frame 502 and heat dissipation hole 4, and the exhaust fan 703 can deliver cold air through the corresponding arc-shaped hole 701, arc-shaped frame 502 and heat dissipation hole 4. Since the bottom of the air guide box 702 and the electrical box 3 are on the same plane, they can be placed stably.

[0030] In summary: When the internal circuit system of the electrical box 3 is powered on, the ceramic electric heater base 2 can be heated. When the temperature of the ceramic electric heater base 2 is within the preset range, no heat dissipation is required. Therefore, the transmission component 6 controls the flow guiding component 5 to block the two sets of heat dissipation holes 4 to prevent external dust from entering. When the temperature of the ceramic electric heater base 2 exceeds the preset value, the internal circuit system of the electrical box 3 can immediately sense it and cut off the power. At this time, heat dissipation is required. Therefore, the transmission component 6 controls the flow guiding component 5 to expose the two sets of heat dissipation holes 4 and simultaneously activates the cooling component 7 to exhaust hot air and inject cold air into the equipment, thereby accelerating the cooling of the ceramic electric heater base 2, improving the cooling effect, reducing the risk of failure due to overheating of the ceramic electric heater base 2, and ensuring the service life of the equipment.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
