Description

Technical Field

[0001] This utility model relates to the field of electric heating plate technology, and specifically to a temperature control device for a planar electric heating plate. Background Technology

[0002] An electric heating plate is a device that converts electrical energy into heat energy to heat objects or spaces. It is widely used in industrial, scientific research, and household applications. Its core principle is to use a resistance heating element to convert electric current into heat, which is then transferred to the target area through a heat-conducting material.

[0003] When electric heating plates are actually used, their temperature adjustment is mostly achieved by using a knob to control a potentiometer. In order to meet the convenience of human-computer interaction, the knob is usually exposed on the outside of the device, which can easily cause accidental touch when operating or moving the device, resulting in changes in the potentiometer resistance value. This causes the actual heating temperature of the electric heating plate to deviate from the preset value, resulting in deviations in experimental data. Therefore, a temperature control device for a planar electric heating plate is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that accidental touches during operation or movement of equipment can easily lead to changes in potentiometer resistance, which in turn causes the actual heating temperature of the electric heating plate to deviate from the preset value, resulting in deviations in experimental data. This invention provides a temperature control device for a planar electric heating plate.

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

[0006] A temperature control device for a flat electric heating plate, comprising:

[0007] The mounting frame has a heating platform on its top;

[0008] A control component, disposed on the outside of the fixed frame, is used to heat the fixed frame. The control component includes a controller, an adjusting component, and a control element. The controller is disposed on the outside of the fixed frame and is used to heat the heating platform. The adjusting component is disposed inside the controller and is used to control the temperature of the heating platform. The control element is disposed inside the adjusting component and is used to adjust the adjusting component.

[0009] Furthermore, the controller includes a control board, which is disposed on the outside of the mounting bracket, and a slot is provided on the outside of the control board.

[0010] Furthermore, the adjusting component includes a plug, which is disposed inside the slot. The plug is hollow inside, and an adjuster and a rotating plate are arranged sequentially inside the plug. The adjuster and the control plate are connected by a wire.

[0011] Furthermore, the control component includes a rotating column that rotates inside the insert block, with one end of the rotating column penetrating through the insert block. A sliding column is slidably connected inside the rotating column, and the sliding column penetrates one end of the rotating column. A guide groove is provided on the outer side of the rotating column, and there are multiple guide grooves. A connecting plate and a sliding plate are sequentially provided on the sliding column relative to the end of the rotating column. The connecting plate slides inside the guide groove. A spring is provided on the outer side of the sliding plate. The spring is sleeved on the outer side of the rotating column, and both ends of the spring are connected to the insert block and the sliding plate, respectively.

[0012] Furthermore, a friction pad is provided on the side of the sliding plate opposite to the rotating plate.

[0013] Furthermore, a connecting block is also provided on the outer side of the sliding column.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention, through the setting of adjustment and control components, achieves the separation of the rotating plate and the sliding plate after adjustment by cooperating with the insert block, rotating plate, rotating column, sliding column, sliding plate, spring, guide groove and connecting plate. This avoids accidental touch during operation or movement of the equipment, which could cause changes in the regulator resistance and thus cause the actual heating temperature of the heating platform to deviate from the preset value, thereby reducing the deviation of experimental data.

[0028] like Figures 1 to 6As shown, a temperature control device for a planar electric heating plate includes: a fixed frame 1, with a heating platform 101 on the top of the fixed frame 1; and a control component, disposed on the outside of the fixed frame 1, for heating the fixed frame 1. The control component includes a controller 2, an adjusting component 3, and a control component 4. The controller 2 is disposed on the outside of the fixed frame 1 for heating the heating platform 101. The adjusting component 3 is disposed inside the controller 2 for controlling the temperature of the heating platform 101. The control component 4 is disposed inside the adjusting component 3 for adjusting the adjusting component 3. Specifically, during use, the temperature is controlled by the controller 2. The heating element 2 and the adjusting element 3 work together to heat the heating platform 101. During the heating process, the adjusting element 3 and the controller 2 are adjusted by the control element 4 to regulate the temperature of the heating platform 101. The heating platform 101 consists of a metal support, an aluminum heating plate, and a graphite plate. When the aluminum heating plate is energized, the heat is conducted to the graphite plate. The graphite plate has a temperature sensor, which transmits the detected temperature change signal to the adjusting element 3. The adjusting element 3 controls the aluminum heating plate to turn on and off to control the temperature. The controller 2 can control the aluminum heating plate during use.

[0029] like Figures 1 to 6 As shown, the controller 2 includes a control board 201, which is located on the outside of the mounting bracket 1. A slot 202 is provided on the outside of the control board 201. Specifically, multiple control buttons are also provided on the outside of the control board 201 to accurately control the temperature of the heating platform 101 during use. An insertion hole is provided inside the slot 202, allowing for quick connection of the adjustment component 3 during use. The control board 201 contains a control module that employs an intelligent control algorithm with a self-tuning function to stabilize the temperature of the aluminum heating plate near the set value, meeting the temperature accuracy requirements of different application scenarios. The control board 201 and the mounting bracket 1 can be connected by bolts or clips, facilitating timely replacement of the heating platform 101 if damaged. A connection groove is also provided inside the slot 202.

[0030] like Figures 1 to 6 As shown, the adjusting component 3 includes a plug 301, which is disposed inside the slot 202. The plug 301 is hollow inside, and an adjuster 302 and a rotating plate 303 are arranged sequentially inside the plug 301. The adjuster 302 is connected to the control plate 201 by a wire. Specifically, during use, the plug 301 is inserted into the slot 202, so that the adjuster 302 inside the plug 301 is connected to the control module. Thus, during use, the control module can be quickly adjusted by the cooperation of the rotating plate 303 and the adjuster 302. The adjuster 302 is a potentiometer. The plug 301 has pins on the outside, which can be inserted into the connecting slot during use. The pins are connected to the adjuster 302 by a wire.

[0031] like Figures 1 to 6 As shown, the control component 4 includes a rotating column 401 that rotates inside the insert block 301, with one end of the rotating column 401 penetrating through the insert block 301. A sliding column 402 is slidably connected inside the rotating column 401, with the sliding column 402 penetrating through one end of the rotating column 401. Multiple guide grooves 405 are provided on the outer side of the rotating column 401. A connecting plate 406 and a sliding plate 403 are sequentially provided on the sliding column 402 relative to the end of the rotating column 401. The connecting plate 406 slides within the guide grooves 405. A spring 404 is provided on the outer side of the sliding plate 403, sleeved on the outer side of the rotating column 401, with both ends of the spring 404 connected to the insert block 301 and the sliding plate 403 respectively. Specifically, during use, the spring 404 controls the sliding plate 403. 03 provides tension to prevent accidental contact with the sliding column 402 during heating, which could cause the rotating plate 303 to rotate. When the regulator 302 needs to be adjusted, first press the sliding column 402 so that the sliding column 402 controls the sliding plate 403 to fit with the rotating plate 303 through the connecting plate 406. Then, the rotating plate 303 is rotated by the sliding column 402. After adjustment, release the sliding column 402 so that the spring 404 pulls the sliding plate 403 to separate from the rotating plate 303 and resets it. When in use, the rotating column 401 works with the guide groove 405 to guide the connecting plate 406 and ensure the stability of the sliding plate 403 during movement. The two ends of the spring 404 can be connected to the sliding plate 403 and the insert block 301 through hooks or pressure plates.

[0032] like Figures 1 to 6 As shown, a friction pad is also provided on the opposite side of the sliding plate 403 and the rotating plate 303. Specifically, the friction pad can increase the friction between the sliding plate 403 and the rotating plate 303 during use, ensuring that the sliding plate 403 can stably drive the rotating plate 303 to rotate. The friction pad can be made of rubber or silicone.

[0033] like Figures 1 to 6 As shown, a connecting block is also provided on the outside of the sliding column 402. Specifically, the shape of the connecting block can be cylindrical, hexagonal prism, or square prism, etc. The connecting block and the sliding column 402 can be connected by a hole or thread.

[0034] like Figures 1 to 6 As shown, the working state of the temperature control device for the planar electric heating plate is as follows: When heating is required, firstly, the sliding plate 403 is controlled to contact the rotating plate 303 through the cooperation of the sliding column 402 and the connecting plate 406. Then, the rotating plate 303 is controlled to rotate through the cooperation of the sliding column 402 and the sliding plate 403. The rotating plate 303 adjusts the regulator 302. Finally, the heating stage 101 is controlled by the control plate 201, so that the heating stage 101 can stably heat the sample during use.

[0035] In summary, this utility model includes: a fixed frame 1, with a heating platform 101 on the top of the fixed frame 1; and a control component, located on the outside of the fixed frame 1, for heating the fixed frame 1. The control component includes a controller 2, an adjusting component 3, and a control component 4. The controller 2 is located on the outside of the fixed frame 1 for heating the heating platform 101. The adjusting component 3 is located inside the controller 2 for controlling the temperature of the heating platform 101. The control component 4 is located inside the adjusting component 3 for adjusting the adjusting component 3. Through the setting of the adjusting component 3 and the control component 4, this utility model achieves the separation of the rotating plate 303 and the sliding plate 403 after adjustment by cooperating with the insert block 301, rotating plate 303, rotating column 401, sliding column 402, sliding plate 403, spring 404, guide groove 405, and connecting plate 406. This avoids accidental touches during operation or movement of the equipment, which could cause changes in the resistance of the regulator 302 and thus cause the actual heating temperature of the heating platform 101 to deviate from the preset value, thereby reducing experimental data deviation.
