Description

Technical Field

[0001] The utility model relates to the technical field of PTC heaters, in particular to a PTC heater with a temperature control device. Background Art

[0002] PTC heating element, also known as PTC heater, is composed of PTC ceramic heating element and aluminum tube. This type of PTC heating element has the advantages of small thermal resistance and high heat exchange efficiency. It is an automatic constant temperature and energy-saving electric heater. Its outstanding feature lies in its safety performance. Under any application conditions, it will not produce the "reddening" phenomenon on the surface of electric heating tube heaters, thereby causing safety hazards such as burns and fire.

[0003] The existing Chinese patent application number 202220456003.6 discloses a PTC heater with a temperature control device, including a tailstock and a PTC heating plate, a mounting shell is installed on one side of the tailstock, a cavity is opened inside the mounting shell, a sliding rheostat and a positive electrode cover are installed inside the cavity, the positive electrode cover is located on the side of the tailstock and is vertically arranged with the sliding rheostat, a baffle is fixedly connected inside the tailstock and at both ends of the sliding rheostat, a slide rod is fixedly connected between the baffles and outside the sliding rheostat, an adjustment button is installed outside the tailstock, one end of the adjustment button is fixedly connected to a slide, the slide runs through the inside of the cavity and slides on the slide rod. By setting a sliding rheostat, the change of resistance is controlled by adjusting the sliding rheostat, and then the change of voltage is adjusted, and then the temperature is controlled to avoid the internal temperature being too high and causing the PTC heating plate to burn out.

[0004] However, the PTC heater still has some shortcomings in actual use. For example, a protective component is set outside the ceramic heating element. Once it is hit on the heater surface, it is easy to cause surface damage, which in turn affects the service life of the heater. At the same time, when the heater is on standby for a short time, heat will be dissipated from the heater surface into the air, causing a certain amount of heat waste. In addition, during the initial heating to the required temperature, the temperature of the heater surface will be dissipated into the air as it rises, which will cause the heater to take a long time to heat up to the required temperature.

[0019] 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.

[0020] The utility model provides a technical solution: comprising a heater component 1, the heater component 1 is wrapped with a heat preservation component 2, the heater component 1 comprises a PTC heating plate 101, a regulating plate 102 is fixedly installed on one side of the PTC heating plate 101, a tail plate 103 is fixedly installed on the other side of the PTC heating plate 101, and a docking magnetic patch 104 is fixedly installed on a side of the tail plate 103 close to the PTC heating plate 101;

[0021] The thermal insulation component 2 includes a connecting plate 201, a thermal insulation cage 202 is fixedly installed on one side of the connecting plate 201, an adsorption magnetic plate 203 is fixedly installed on the side of the thermal insulation cage 202 away from the connecting plate 201, two plug holes 204 are provided on the edges of the front side of the adsorption magnetic plate 203, and a sliding shaft 205 is inserted in a plurality of the plug holes 204. The plurality of sliding shafts 205 can play a certain protective role, which can prevent external collisions from directly acting on the surface of the PTC heating plate 101, so that the entire thermal insulation cage 202 covers the entire PTC heating plate 101. After covering, the heat dissipated from the surface of the PTC heating plate 101 will not be dissipated in the air, thereby reducing the rate of increase of the surface temperature of the PTC heating plate 101. At the same time, in the standby state, the thermal insulation cage 202 can also play a heat preservation role.

[0022] In this embodiment, a plurality of the sliding shafts 205 are disposed between the regulating plate 102 and the tail plate 103 , and two ends of the sliding shafts 205 are fixedly connected to a side surface of the regulating plate 102 and a side surface of the tail plate 103 , respectively.

[0023] A circular shaft 106 is fixedly installed on the top surface of the regulating plate 102, and a rotating plate 107 is rotatably sleeved on the top of the side of the circular shaft 106. A threaded hole is provided on the top surface of the rotating plate 107 away from the circular shaft 106, and a limit screw 108 is threadedly inserted in the threaded hole. The position of the limit screw 108 can be adjusted by rotating the rotating plate 107. When the insulation cage 202 needs to be folded, the limit screw 108 can be rotated to one side of the insulation cage 202, and then the limit screw 108 can be lowered by twisting it, and the insulation cage 202 is limited by the contact between the limit screw 108 and the surface of the adsorption magnetic plate 203.

[0024] A regulating button 105 is disposed on a side of the regulating plate 102 away from the PTC heating plate 101 .

[0025] The opposite surfaces of the adsorption magnetic plate 203 and the docking magnetic plate 104 are arranged to attract each other with opposite poles. By adsorbing the adsorption magnetic plate 203 and the docking magnetic plate 104 together, the entire heat preservation cage 202 can cover the entire PTC heating plate 101.

[0026] When the PTC heater is working, in order to make the surface of the PTC heater rise to the required temperature quickly, the limit screw 108 can be turned, and the limit screw 108 can be rotated to move it upward, thereby disconnecting the limit of the heat preservation cage 202, and then the heat preservation cage 202 is manually pulled to change it from the layered folding state to the unfolded state, and the entire heat preservation cage 202 can cover the entire PTC heating plate 101 by adsorbing the magnetic plate 203 and the docking magnetic plate 104 together. After covering, the heat dissipated from the surface of the PTC heating plate 101 will not be dissipated in the air, thereby reducing the speed of increasing the surface temperature of the PTC heating plate 101. At the same time, in the standby state, The heat preservation cage 202 can be used to keep warm. When the heater is in use, the adsorption magnetic plate 203 can be directly disconnected from the docking magnetic plate 104. After disconnection, the heat preservation cage 202 is pushed to fold the heat preservation cage 202. After folding, the heat preservation cage 202 needs to be limited to prevent the heat preservation cage 202 from unfolding. The limit screw 108 can be rotated to one side of the heat preservation cage 202, and then the limit screw 108 can be lowered by twisting it. The heat preservation cage 202 is limited by the contact between the limit screw 108 and the surface of the adsorption magnetic plate 203. After the heat preservation cage 202 is folded, the PTC heating plate 101 can be leaked out, thereby playing a heating role.

[0027] To sum up, the PTC heater with a temperature control device can make the entire thermal insulation cage 202 cover the entire PTC heating plate 101 by adsorbing the magnetic plate 203 and the docking magnetic plate 104 together. After covering, the heat dissipated from the surface of the PTC heating plate 101 will not dissipate in the air, thereby reducing the rate of increase in the surface temperature of the PTC heating plate 101, while saving energy consumption and improving the heating efficiency of the heater. At the same time, in the standby state, the thermal insulation cage 202 can also play a role in heat preservation, which is more practical. Furthermore, the thermal insulation cage 202 and several sliding shafts 205 can play a certain protective role, which can prevent external collisions from directly acting on the surface of the PTC heating plate 101.
