Description

Technical Field

[0001] The utility model relates to the technical field of heating plates, in particular to a ceramic heating plate with a protection function. Background Technique

[0002] The ceramic heating plate, as a new type of heating element integrating high-efficiency heating and excellent heat insulation performance, its core part is made of ceramic materials with high temperature resistance and corrosion resistance. This material can not only maintain stable physical and chemical properties under extreme temperature conditions, but also has good insulation and heat conduction properties, making the ceramic heating plate an indispensable key component in many fields such as industrial heating, household appliances, and medical equipment. Its working principle is to convert electrical energy into heat energy through an internal electric heating element (such as a resistance wire), and then evenly distribute the heat to the object to be heated through the good heat conduction of the ceramic matrix, achieving an efficient and uniform heating effect.

[0003] The strength of ceramics is relatively low, fragile and not resistant to impact. In order to improve the overall strength of the ceramic heating plate and increase its protection performance, a common practice is to fixedly install a heat-conducting metal plate on its top. This metal plate can not only provide additional mechanical protection for the ceramic heating plate, but also serve as a medium for heat conduction to improve the heat transfer efficiency. After long-term use, due to being exposed to the air and experiencing high-temperature cycles, the heat-conducting metal plate is extremely prone to oxidation reactions, resulting in problems such as surface corrosion and a decline in heat conduction performance. Due to its fixed connection method with the ceramic heating plate, it is often difficult to achieve convenient disassembly and replacement. Content of the Utility Model

[0004] The purpose of the utility model aims to solve at least one of the technical defects.

[0005] Therefore, an object of the utility model is to propose a ceramic heating plate with a protection function to solve the problems mentioned in the background technique and overcome the deficiencies existing in the prior art.

[0006] To achieve the above object, an embodiment of one aspect of the present utility model provides a ceramic heating plate with a protection function, including a control bottom box. The top surface of the control bottom box is fixedly installed with a plurality of support columns through bolts. The top surfaces of the plurality of support columns are fixedly connected with a heat insulation frame. The inside of the heat insulation frame is fixedly installed with a heating plate through bolts. The heating plate is electrically connected with the control bottom box through a wire. A heat conduction plate is placed on the bottom surface of the heating plate. The top surface of the heat insulation frame is fixedly connected with two baffle plates. A connecting rod is fixedly connected between the two baffle plates. The top surface of the heat insulation frame is fixedly connected with a locking plate. The heating plate is located between the locking plate and the connecting rod. The outer surface of the connecting rod is rotatably connected with a pressing frame. The bottom surface of the pressing frame is in fit with the top surface of the heat conduction plate. The front surface of the pressing frame is fixedly connected with a vertical plate. Two springs are fixedly connected to the outside of the vertical plate. One side of the two springs away from the vertical plate is fixedly connected with a pulling plate. The inside of the pulling plate is fixedly connected with a locking pin. The outer surface of the locking pin is slidably connected with the vertical plate. One end of the locking pin away from the pulling plate is engaged with the locking plate.

[0007] Preferably, according to any of the above solutions, support plates are fixedly connected to both the left and right sides of the heat conduction plate. Both support plates are slidably connected with the heating plate. The bottom surfaces of both support plates are in fit with the top surface of the heat insulation frame.

[0008] Preferably, according to any of the above solutions, sliding trays are provided on the inner sides of both support plates. Sliding grooves are provided on both the left and right sides of the heating plate. The sliding trays are slidably connected with the heating plate through the sliding grooves.

[0009] Preferably, according to any of the above solutions, a plurality of pin shafts are fixedly connected to the top surface of the heating plate. Pin holes are provided on the bottom surface of the heat conduction plate. The pin shafts are slidably connected with the heat conduction plate through the pin holes.

[0010] Preferably, according to any of the above solutions, a rotation hole is provided through the side surface of the pressing frame. The depth of the rotation hole is equal to the length of the connecting rod. The pressing frame is rotatably connected with the connecting rod through the rotation hole.

[0011] Preferably, according to any of the above solutions, a locking hole is provided on the front surface of the locking plate. One end of the locking pin away from the pulling plate is engaged with the locking plate through the locking hole.

[0012] Preferably, according to any of the above solutions, a U-shaped frame is fixedly connected to the top surface of the pressing frame. A cover plate is slidably connected to the inner wall of the U-shaped frame. The cover plate is fixedly connected with the pressing frame through bolts. The cover plate corresponds to the heat conduction plate up and down.

[0013] Compared with the prior art, the advantages and beneficial effects of the present utility model are as follows:

[0014] 1. When it is necessary to replace the heat-conducting metal plate, the plate can be pulled outwards to drive the locking pin to move out of the locking hole, unlocking the vertical plate. Then, the pressing frame can be pulled upwards to rotate around the connecting rod until the pressing frame rotates to an appropriate angle, unlocking the heat-conducting plate. Subsequently, the heat-conducting plate can be quickly removed from the heating plate, facilitating the disassembly of the heat-conducting plate from the heating plate and greatly improving the replacement efficiency of the heat-conducting plate.

[0015] 2. After the old heat-conducting plate is disassembled, the new heat-conducting plate is placed on the heating plate along the chute.

After the heating plate is used, the cover plate can be inserted into the U-shaped frame and locked on the pressing frame by bolts, blocking the upper surface of the heat-conducting plate and preventing external dust from accumulating on the heat-conducting plate.

The sides of the two springs 10 away from the vertical plate 9 are fixedly connected to a pulling plate 11. A locking pin 12 is fixedly connected to the inside of the pulling plate 11. The outer surface of the locking pin 12 is slidably connected to the vertical plate 9. One end of the locking pin 12 away from the pulling plate 11 is engaged with the locking plate 8.

[0024] As an optional technical solution of the present utility model, support plates 13 are fixedly connected to both the left and right sides of the heat conduction plate 5.

[0026] As an optional technical solution of the present utility model, a plurality of pin shafts 16 are fixedly connected to the top surface of the heating plate 4. Pin holes 17 are opened on the bottom surface of the heat conduction plate 5. The pin shafts 16 are slidably connected to the heat conduction plate 5 through the pin holes 17. The new heat conduction plate 5 is placed on the heating plate 4 along the sliding grooves 15. At this time, the pin shafts 16 will be inserted into the pin holes 17, which can improve the stability of the heat conduction plate 5.

[0027] As an optional technical solution of the present utility model, a rotation hole 18 is penetrated through the side surface of the pressing frame 81. The depth of the rotation hole 18 is equal to the length of the connecting rod 7. The pressing frame 81 is rotatably connected to the connecting rod 7 through the rotation hole 18. Pull the pressing frame 81 upward to rotate it around the connecting rod 7 until the pressing frame 81 rotates to a suitable angle, then the locking of the heat conduction plate 5 can be released, and then the heat conduction plate 5 can be quickly removed from the heating plate 4.

[0028] As an alternative technical solution of the present utility model, a locking hole 19 is formed on the front surface of the locking plate 8. One end of the locking pin 12 away from the pulling plate 11 is clamped with the locking plate 8 through the locking hole 19.

[0030] A ceramic heating plate with a protection function has the following working principle:

[0031] 1): When the heat-conducting metal plate needs to be replaced, the pulling plate 11 can be pulled outwards to drive the locking pin 12 to move out of the locking hole 19, and the locking of the vertical plate 9 can be released. Then, the pressing frame 81 can be pulled upwards to rotate around the connecting rod 7 until the pressing frame 81 rotates to an appropriate angle, and the locking of the heat-conducting plate 5 can be released.

[0032] 2): After the old heat-conducting plate 5 is disassembled, the new heat-conducting plate 5 is placed on the heating plate 4 along the sliding groove 15. Through the sliding fit between the sliding support 14 and the sliding groove 15, it is convenient for the pin shaft 16 to align with the pin hole 17. At this time, the bottom surfaces of the support plates 13 are all in contact with the top surface of the heat-insulating frame 3.

[0033] 3): The pressing frame 81 is reset and the vertical plate 9 is locked through the locking pin 12, so that the installation of the heat-conducting plate 5 can be quickly completed. The installation and disassembly of the heat-conducting plate 5 are both very convenient.

[0034] In summary, for the ceramic heating plate with a protection function, when it is necessary to replace the heat-conducting metal plate, the plate 11 can be pulled outwards to drive the locking pin 12 to move out of the locking hole 19, unlocking the vertical plate 9. Subsequently, the pressing frame 81 can be pulled upwards to rotate around the connecting rod 7 until the pressing frame 81 rotates to an appropriate angle, unlocking the heat-conducting plate 5. Then, the heat-conducting plate 5 can be quickly removed from the heating plate 4, facilitating the disassembly of the heat-conducting plate 5 from the heating plate 4 and greatly improving the replacement efficiency of the heat-conducting plate 5. After the old heat-conducting plate 5 is disassembled, the new heat-conducting plate 5 is placed on the heating plate 4 along the sliding groove 15. Through the sliding fit between the sliding support 14 and the sliding groove 15, it is convenient for the pin shaft 16 to align with the pin hole 17. At this time, the bottom surfaces of the support plates 13 are all in contact with the top surface of the heat-insulating frame 3, supporting the heat-conducting plate 5 to prevent damage to the heating plate 4. Subsequently, the pressing frame 81 is reset and the vertical plate 9 is locked by the locking pin 12, quickly completing the installation of the heat-conducting plate 5.
