Description

Technical Field

[0001] This utility model belongs to the technical field of heating equipment, specifically a ceramic electric heating plate. Background Technology

[0002] Electric heating plates, as devices that convert electrical energy into heat energy, are widely used in many fields such as electric stoves, heating equipment, water heaters, medical instruments, and industrial heating. Ceramic materials are widely used as the base material for electric heating plates due to their high insulation strength, excellent high-temperature and corrosion resistance, and long service life. During operation, the current flowing through the heating element generates Joule heat. The heat is first conducted to the ceramic substrate surrounding the heating element, and then transferred outwards from the surface of the ceramic substrate, thus achieving heat exchange with the heated object or the surrounding air.

[0003] However, existing ceramic heating plates are typically configured with a closed outer shell structure, which causes heat to accumulate inside after the heating task is completed, making it difficult to dissipate quickly. This results in the heating plate surface remaining at a high temperature for an extended period. This slow heat dissipation not only affects the continuous operating efficiency of the equipment but also poses a safety hazard of burns to operators.

[0004] Therefore, there is an urgent need for a heating plate structure that can balance rapid heating and efficient heat dissipation. Summary of the Invention

[0005] Therefore, it is necessary to provide a ceramic heating plate with a liftable base plate on the bottom side of the mounting shell. This allows the operator to lower the base plate after the heating plate has finished heating, allowing air to flow on both sides of the ceramic heating plate, thereby achieving rapid cooling of the heating plate and preventing burns to the operator.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A ceramic electric heating plate includes a mounting base, on the center of which the heating plate is mounted. A heat dissipation structure is provided on the bottom side of the mounting base, including a rotating plate. Multiple rotating plates are rotatably connected to the bottom side of the mounting base. A lifting base plate is slidably connected to the bottom side of the mounting base. Fireproof cotton is provided on the inner side of the lifting base plate. A connecting groove is provided on the side of the lifting base plate. The bottom side of the rotating plate is slidably connected to the lifting base plate through the connecting groove. Clamping structures are provided on both sides of the mounting base.

[0007] Optionally, in one embodiment of the present invention, a plurality of the rotating plates are arranged equidistantly in sequence, and a second spring is fixedly connected between each side of the lifting base and the mounting seat.

[0008] Optionally, in one embodiment of the present invention, a control rod is fixedly connected to one end of one of the rotating plates located in the middle, the control rod is rotatably connected to the mounting base, and the side of the control rod abuts against the mounting base.

[0009] Optionally, in one embodiment of the present invention, a locking rod is slidably connected to the end of the control rod, and a first spring is fixedly connected between the locking rod and the control rod.

[0010] Optionally, in one embodiment of the present invention, the mounting base has a locking groove on its side, and the locking groove has an L-shaped structure.

[0011] Optionally, in one embodiment of the present invention, the clamping structure includes a first toothed bar and a second toothed bar, and a first toothed bar and a second toothed bar are slidably connected to both sides of the mounting base, and a soft clamping bar is provided between the two first toothed bars and the two second toothed bars.

[0012] Optionally, in one embodiment of the present invention, a reversing gear is rotatably connected to each side of the mounting base, and the first and second racks located on the same side mesh with the two sides of the reversing gear.

[0013] Optionally, in one embodiment of the present invention, the tooth groove portions on the sides of the first tooth bar and the second tooth bar are of equal length, and a fourth spring is fixedly connected between the bottom side of the first tooth bar and the mounting base.

[0014] Optionally, in one embodiment of the present invention, a release rod is provided between the two first toothed rods, and a third spring is fixedly connected between the release rod and the mounting base.

[0015] Optionally, in one embodiment of the present invention, a positioning groove is provided at the end of the first toothed rod, and a beveled protrusion is provided at each end of the release rod. The first toothed rod engages with the beveled protrusion on the release rod through the positioning groove.

[0016] Compared with the prior art, the ceramic electric heating plate provided by this utility model has the following characteristics: The heating plate is installed in the middle of the mounting base for heating. After heating is complete, to quickly dissipate heat from the heating plate, the operator can rotate the rotating plate located at the bottom of the mounting base. This causes the bottom of the rotating plate to slide within the connecting groove on the lifting base plate, simultaneously pulling the lifting base plate downwards. At this point, the rotating plate rotates to a vertical position, exposing the bottom part of the heating plate. This allows both sides of the heating plate to dissipate heat simultaneously, causing the temperature of the heating plate to drop rapidly and preventing burns to the operator. On the other hand, when the rotating plate is in a horizontal position, the lifting base plate is in the top position, and the bottom of the mounting base is in a closed state. Combined with the fireproof cotton installed inside the lifting base plate, better heat preservation can be achieved, thereby improving the heating speed of the ceramic heating plate and facilitating its use.

[0021] To achieve higher thermal conductivity and faster heat dissipation in ceramic heating plates, a ceramic heating plate was designed, with the specific scheme as follows: Example 1

[0022] like Figure 1-6 As shown, a ceramic electric heating plate includes a mounting base 1, an electric heating plate 2 mounted in the middle of the mounting base 1, a heat dissipation structure 3 provided on the bottom side of the mounting base 1, the heat dissipation structure 3 including a rotating plate 303, multiple rotating plates 303 rotatably connected to the bottom side of the mounting base 1, a lifting base plate 301 slidably connected to the bottom side of the mounting base 1, fireproof cotton 304 provided on the inner side of the lifting base plate 301, a connecting groove 305 opened on the side of the lifting base plate 301, the bottom side of the rotating plate 303 slidably connected to the lifting base plate 301 through the connecting groove 305, and clamping structures 4 provided on both sides of the mounting base 1.

[0023] Multiple rotating plates 303 are arranged equidistantly in sequence. Second springs 309 are fixedly connected to the two sides of the lifting base 301 and the mounting seat 1, respectively. A control rod 302 is fixedly connected to the end of one of the rotating plates 303 located in the middle. The control rod 302 is rotatably connected to the mounting seat 1, and its side abuts against the mounting seat 1. A locking rod 307 is slidably connected to the end of the control rod 302. A first spring 308 is fixedly connected between the locking rod 307 and the control rod 302. A locking groove 306 is provided on the side of the mounting seat 1. The locking groove 306 has an L-shaped structure. To facilitate the control of the rotation of the rotating plates 303 and the lifting position of the lifting base 301, a first spring 309 is fixedly connected to the middle rotating plate 303. A control lever 302 is connected to the end of the heating plate 303. By rotating the control lever 302, the rotating plate 303 can be driven and its rotation angle adjusted. At the same time, a second spring 309 is connected between the lifting base plate 301 and the mounting base 1, which keeps the lifting base plate 301 in a lowered state. This facilitates the cooling of the heating plate 2. When the rotating plate 303 is rotated to a horizontal state by the control lever 302, the lifting base plate 301 is raised. At the same time, the operator needs to slide the locking rod 307 at the end of the control lever 302 so that the locking rod 307 can engage with the locking groove 306 of the L-shaped structure, thereby fixing the lifting base plate 301 in a closed state to the bottom side of the mounting base 1 and improving the heating efficiency of the heating plate 2.

[0024] The clamping structure 4 includes a first toothed bar 401 and a second toothed bar 402. A first toothed bar 401 and a second toothed bar 402 are slidably connected to each side of the mounting base 1. A clamping rod 403 is provided between each of the two first toothed bars 401 and the two second toothed bars 402. A reversing gear 407 is rotatably connected to each side of the mounting base 1. The first toothed bars 401 and the second toothed bars 402, located on the same side, mesh with the two sides of the reversing gear 407. The tooth grooves on the sides of the first toothed bars 401 and the second toothed bars 402... Two toothed rods of equal length are fixedly connected to the bottom of the first toothed rod 401 and the mounting base 1 by a fourth spring 406. A release rod 404 is provided between the two first toothed rods 401, and a third spring 405 is fixedly connected between the release rod 404 and the mounting base 1. A positioning groove 408 is provided at the end of the first toothed rod 401, and a beveled protrusion is provided at each end of the release rod 404. The first toothed rod 401 engages with the beveled protrusion on the release rod 404 through the positioning groove 408. When heating some slender vessels, this is to prevent the vessels from falling out. In the current tilted state, a clamping rod 403 is provided on each side of the mounting base 1. The two clamping rods 403 are respectively installed between two first toothed rods 401 and two second toothed rods 402. A reversing gear 407 meshes between the first toothed rods 401 and the second toothed rods 402 on the same side, so that the first toothed rods 401 and the second toothed rods 402 can only slide synchronously in opposite directions, which facilitates the operator to adjust the position of the clamping rods 403. On the other hand, a fourth spring 40 is connected between the first toothed rod 401 and the mounting base 1. 6. This can improve the clamping effect of the clamping rod 403 on the heating vessel and enhance the stability of the vessel. On the other hand, to facilitate operation, when the first toothed rod 401 slides to the edge of the mounting base 1, the first toothed rod 401 will engage with the inclined protrusion at the end of the release rod 404 through the positioning groove 408. At this time, the operator can release the first toothed rod 401 and the second toothed rod 402 by pressing the release rod 404, thus completing the clamping and fixing of the vessel and preventing the vessel from tipping over during heating.

[0025] Equipment Description: The heating plate 2 is installed in the middle of the mounting base 1 for heating. After heating is completed, in order to quickly dissipate heat from the heating plate 2, the operator can rotate the rotating plate 303 located on the bottom side of the mounting base 1, so that the bottom side of the rotating plate 303 slides in the connecting groove 305, and drives the lifting base plate 301 to slide to the bottom. At this time, the rotating plate 303 rotates to a vertical position, and the bottom part of the heating plate 2 is exposed, so that both sides of the heating plate 2 can dissipate heat at the same time, so that the temperature of the heating plate 2 drops rapidly and avoids burns. On the other hand, when the rotating plate 303 is in a horizontal position, the lifting base plate 301 is in the top position. At this time, the bottom side of the mounting base 1 is in a closed state. The fireproof cotton 304 set inside the lifting base plate 301 can provide heat preservation, thereby improving the heating speed of the ceramic heating plate 2 and making it convenient to use.

[0026] To facilitate the rotation of the rotating plate 303 and the raising and lowering of the lifting base plate 301, a control rod 302 is connected to one end of the rotating plate 303 located in the middle. By rotating the control rod 302, the rotating plate 303 can be controlled and its rotation angle adjusted. At the same time, a second spring 309 is connected between the lifting base plate 301 and the mounting base 1, which can keep the lifting base plate 301 in a lowered state. At this time, it is convenient to cool down the heating plate 2. When the rotating plate 303 is rotated to a horizontal state by the control rod 302, the lifting base plate 301 is raised. The operator needs to slide the locking rod 307 at the end of the control rod 302 so that the locking rod 307 engages with the locking groove 306, thereby fixing the lifting base plate 301, keeping the bottom side of the mounting base 1 closed, and improving the heating efficiency of the heating plate 2.

[0027] To prevent the vessel from tipping over when heating a slender vessel, a clamping rod 403 is provided on each side of the mounting base 1. The two clamping rods 403 are respectively installed between two first toothed rods 401 and two second toothed rods 402. A reversing gear 407 meshes between the first toothed rods 401 and the second toothed rods 402 on the same side, allowing the first toothed rods 401 and 402 to slide synchronously in opposite directions, facilitating the operator's adjustment of the position of the clamping rods 403. Furthermore, the first toothed rods 401 are connected to the mounting base 1... The fourth spring 406 enhances the clamping effect of the clamping rod 403 on the heating vessel and improves clamping stability. On the other hand, to facilitate operation, when the first toothed rod 401 slides to the edge of the mounting base 1, the first toothed rod 401 will engage with the inclined protrusion at the end of the release rod 404 through the positioning groove 408. At this time, the operator can release the first toothed rod 401 and the second toothed rod 402 by pressing the release rod 404, thus completing the clamping and fixing of the vessel and preventing the vessel from tipping over during heating.

[0028] The ceramic heating plate of this solution is equipped with a rotating plate 303 and a lifting base plate 301. The rotating plate 303 can be rotated to a vertical position, exposing the bottom side of the heating plate 2, so that heat dissipation can be achieved from both sides at the same time, improving heat dissipation efficiency, avoiding overheating problems caused by slow heat dissipation of the heating plate 2, preventing burns, and improving safety in use. The lifting base plate 301 is equipped with fireproof cotton on the inside, which can improve the heating efficiency of the heating plate 2 when it is in a closed state.

[0029] A control lever 302 is provided to adjust the angle of the rotating plate 303. At the same time, the lifting base plate 301 is automatically kept in the lowered state under the action of the second spring 309. The engagement of the locking rod and the L-shaped locking groove ensures that the lifting base plate 301 is fixed in the closed state, preventing loosening and ensuring the stability of the equipment.

[0030] A clamping rod 403 is provided on each side of the mounting base 1. They slide synchronously in opposite directions to ensure that the slender vessel is evenly clamped. The clamping can be quickly released by pressing the release rod 404. The operation is convenient, prevents tipping during the heating process, and improves experimental safety. Example 2

[0031] In this embodiment, the structure of the heating plate 2 is basically the same as that of embodiment 1. The difference is that an insulating heat-conducting plate is added between the bottom of the heating plate 22 and the lifting base plate 301 to serve as a safety isolation layer, preventing users from contacting live and high-heat components and ensuring normal heat transfer.

[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
