Description

Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to a heater with a PTC heating component embedded therein. Background Art

[0002] PTC heater is a new type of electric heater consisting of a PTC heating component, positive and negative electrode sheets, and a packaging shell. Due to its technical advantages such as high heat exchange efficiency, safety and reliability, automatic constant temperature, low power consumption, and fast heating, it has become one of the most widely used electric heaters.

[0003] Chinese utility model patent CN217825399U discloses a heater with a built-in PTC heating component, including a PTC heating component and a stretched aluminum part. The PTC heating component includes a heating element and a first electrode sheet and a second electrode sheet sandwiched above and below the heating element. The heating element, the first electrode sheet and the second electrode sheet are covered with an insulating protective film. The PTC component is fixed in the stretched aluminum part. By directly fixing the PTC heating component in the stretched aluminum part, the PTC heating component can be fitted with the inner wall of the stretched aluminum part, so that the heat on the PTC heating component can be directly transferred to the stretched aluminum part. Compared with existing heaters, the heat transfer performance is better and the power is more stable. After the PTC heating component is placed in the stretched aluminum part, the PTC heating component is directly pressed by pressure. There is no need to add a thermal conductive gasket between the PTC heating component and the stretched aluminum part. The PTC heating component can be firmly fixed in the stretched aluminum part to prevent the PTC heating component from loosening, which can improve the heat transfer between the PTC heating component and the stretched aluminum part.

[0004] Although the above patent has the advantages of better heat transfer performance and more stable power, when in use, after the device is placed in the liquid to be heated, the above patent can only quickly heat the liquid around the device, and then transfer the heat to the liquid far away through the thermal conductivity between the liquids. Therefore, it takes a long time to wait for the liquid to be heated to the specified temperature. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a heater with a built-in PTC heating component, comprising a controller, a resistance temperature sensor, and a PTC heating component, wherein the controller and the resistance temperature sensor are connected via a power cord, and the resistance temperature sensor and the PTC heating component are connected via an electric wire, a first fixing ring is fixedly mounted on the top of the PTC heating component, a second fixing ring is fixedly connected to the bottom of the PTC heating component, and the resistance temperature sensor is mounted inside the first fixing ring;

[0007] A circulation component is fixedly installed on the inner walls of the first fixing ring and the second fixing ring, and the circulation component is used to control the circulation of liquid inside the ceramic heat-conducting column.

[0008] Further: the PTC heating component includes a ceramic heat-conducting column, a slot and a heating wire. The ceramic heat-conducting column is fixedly connected between the first fixing ring and the second fixing ring. The ceramic heat-conducting column is provided with a slot inside, and multiple heating wires are installed inside the slot.

[0011] Furthermore: a display screen is embedded in the outer wall of the controller, and control buttons are fixedly installed on the outer wall of the controller.

[0012] The utility model has the following beneficial effects:

[0013] Compared with the existing technology, by setting a ceramic heat-conducting column, a piezoelectric ceramic motor, a drive shaft and an auger, when the equipment starts to heat the surrounding liquid, the piezoelectric ceramic motor is turned on, and the auger is driven to rotate by the drive shaft. When the auger rotates, the liquid around the equipment can be sucked in from the top of the ceramic heat-conducting column, and then after being heated by the ceramic heat-conducting column, it is discharged from the bottom of the ceramic heat-conducting column, so that the liquid can be circulated inside the ceramic heat-conducting column, which solves the problem in the existing technology that it can only quickly heat the liquid around the equipment but cannot directly heat the liquid at a farther position.

[0023] When in use, place the device in the liquid, then set the required temperature through the controller 1, and then transmit current to the PTC heating component through the wire. Then the temperature of the PTC heating component begins to rise, heating the surrounding liquid. Then turn on the circulation component to make the liquid circulate inside the PTC heating component to achieve rapid heating of the liquid. While the wire transmits electricity, the current passes through the resistance temperature sensor 2 and analyzes the real-time temperature through the resistance.

[0024] The PTC heating component includes a ceramic thermal conductive column 4, a slot 401 and a heating wire 203. The ceramic thermal conductive column 4 is fixedly connected between the first fixing ring 3 and the second fixing ring 5. The ceramic thermal conductive column 4 has a slot 401 formed inside, and multiple heating wires 203 are installed inside the slot 401.

[0025] During use, current enters the heating wire 203 , and then the heating wire 203 begins to heat up, and then the temperature is transferred to the surrounding liquid through the ceramic heat-conducting column 4 .

The inner wall of the first fixed ring 3 is fixedly connected to the first fixed frame 6, the inside of the first fixed frame 6 is fixedly connected to the piezoelectric ceramic motor 7, the output end of the piezoelectric ceramic motor 7 is fixedly connected to the drive shaft 8, the outer wall of the drive shaft 8 is fixedly connected to the auger 9, and the auger 9 is located inside the ceramic heat-conducting column 4.

[0027] When in use, the piezoelectric ceramic motor 7 is turned on and the auger 9 is driven to rotate through the drive shaft 8. When the auger 9 rotates, the liquid around the equipment can be sucked in from the top of the ceramic heat-conducting column 4, and then after being heated by the ceramic heat-conducting column 4, it is discharged from the bottom of the ceramic heat-conducting column 4, so that the liquid can circulate inside the ceramic heat-conducting column 4.

[0030] A display screen 101 is embedded in the outer wall of the controller 1 , and a control button 102 is fixedly mounted on the outer wall of the controller 1 .

[0031] When in use, the required temperature can be set through the control button 102; the real-time temperature of the liquid can be displayed through the display screen 101.

[0032] Working principle: first place the device in the liquid, then set the required temperature through the controller 1, then transmit the current to the heating wire 203 through the wire, then the heating wire 203 begins to heat up, and then the temperature is transmitted to the surrounding liquid through the ceramic thermal conductive column 4, and then turn on the piezoelectric ceramic motor 7, and drive the auger 9 to rotate through the drive shaft 8. When the auger 9 rotates, the liquid around the device can be sucked in from the top of the ceramic thermal conductive column 4, and then after being heated by the ceramic thermal conductive column 4, it is discharged from the bottom of the ceramic thermal conductive column 4, so that the liquid can be circulated inside the ceramic thermal conductive column 4.
