[0027] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] Please refer to Figures 1 to 5As shown, an embodiment of this utility model provides a portable constant-temperature electronic antipruritic device, including a lower housing 1 and an upper housing 2. The upper housing 2 is fixedly installed on the top of the lower housing 1. A heating hole 103 is opened at the bottom of one end of the lower housing 1, and a ceramic heating element 4 is fixedly installed inside the heating hole 103. A controller 3 is fixedly installed inside the lower housing 1, and the ceramic heating element 4 is electrically connected to the controller 3. A blowing assembly is provided inside the lower housing 1. The blowing assembly includes a micro air pump 5 and an air distribution assembly 501. The air distribution assembly 501 includes an annular tube 5011, and the bottom of the annular tube 5011 is fixedly connected to an outlet. The air pipe 5012 has multiple outlet pipes 5012, which are arranged in a ring-shaped equidistant array at the bottom of the ring pipe 5011. The top of the ring pipe 5011 is connected to the inlet pipe 5013. The outlet of the micro air pump 5 is connected to the inlet pipe 5013 through the connecting pipe 502. The bottom of the lower housing 1 near the heating hole 103 has mounting holes 102 that correspond one-to-one with the outlet pipes 5012. The outlet pipes 5012 are fixedly inserted into the inside of the mounting holes 102. The ceramic heating element 4 is located inside the ring pipe 5011. The micro air pump 5 is electrically connected to the controller 3.

[0029] The controller 3 provides power distribution and control signals for the entire instrument. When the controller 3 receives a command to activate heating, it controls the ceramic heating element 4 to operate. The ceramic heating element 4 generates heat, which is applied to the skin surface through the heating hole 103. The high temperature destroys the itch-inducing substances injected into the body after mosquito bites, thus achieving an anti-itch effect. When the blowing function is needed, the controller 3 supplies power to the micro air pump 5. The micro air pump 5 operates, forcing air through the connecting pipe 502 and the air inlet pipe 5013 into the annular pipe 5011, and then blowing it out evenly through multiple air outlet pipes 5012 arranged in an annular equidistant array, thus blowing air onto the heated area or skin surface.

[0030] In this embodiment, an air inlet 101 is provided at one end of the lower housing 1 near the heating hole 103. The air inlet nozzle 503 of the micro air pump 5 is inserted into the air inlet 101, and an air inlet filter 504 is fixedly installed inside the air inlet 101.

[0031] When the miniature air pump 5 is working, it draws in outside air through the air inlet 101 via the air inlet nozzle 503. The air inlet filter 504 filters out dust, impurities, and other contaminants from the air, preventing them from entering the miniature air pump 5 and affecting its performance and lifespan. It also prevents impurities in the blown-out air from irritating the skin.

[0032] In this embodiment, a temperature measuring module 401 is fixedly installed at the lower end of the controller 3, and the controller 3 is electrically connected to the temperature measuring module 401.

[0033] The temperature measurement module 401 monitors the temperature near the ceramic heating element 4 in real time. It transmits the measured temperature data to the controller 3. The controller 3 compares the received temperature data with a preset temperature value. If the actual temperature is lower than the preset value, it increases the power supply to the ceramic heating element 4 to generate more heat; if the actual temperature is higher than the preset value, it reduces the power supply to the ceramic heating element 4, thereby achieving constant temperature control.

[0034] In this embodiment, a battery compartment is provided inside the lower housing 1, and a battery 6 is installed inside the battery compartment.

[0035] Battery 6 serves as the power source for the entire instrument, providing power to various electrical components such as controller 3, ceramic heating element 4, miniature air pump 5, and temperature measurement module 401, so as to facilitate the portability of the antipruritic device.

[0036] Furthermore, a battery cover 7 is installed at the bottom of the lower housing 1.

[0037] The battery cover 7 is used to seal the battery compartment, preventing the battery 6 from accidentally falling out. It also protects the battery 6 from dust, moisture, and other contaminants that could affect its performance. When it's time to replace the battery 6, simply open the battery cover 7.

[0038] In this embodiment, a switch button 8 is installed on the side of the lower housing 1.

[0039] Switch button 8 is used to control the power supply of the entire instrument. Pressing switch button 8 turns on the circuit, the battery 6 starts to power the instrument, the controller 3 starts, and the instrument enters the operable state; pressing switch button 8 again turns off the circuit and the instrument stops working.

[0040] In this embodiment, a function button 9 is installed on the top of the upper housing 2, and the function button 9 is electrically connected to the controller 3.

[0041] It should be noted that in this embodiment, the controller 3 uses a PIC16F1827 microprocessor, the micro air pump 5 uses a Qihai QH-200 micro air pump, and the temperature measurement module 401 uses a DS18B20 temperature sensor.

[0042] Working principle: Function button 9 can be set to different function modes, such as heating mode alone, blowing mode alone, and a combination of heating and blowing. When the user presses the corresponding function button 9, the button signal is transmitted to the controller 3. The controller 3 controls the working status of components such as the ceramic heating element 4 and the miniature air pump 5 according to the received signal to realize different functions.

[0043] Furthermore, a running indicator light 10 is fixedly embedded on the top of the upper housing 2, and the running indicator light 10 is electrically connected to the controller 3.

[0044] The operation indicator light 10 is used to display the working status of the instrument. When the instrument is powered on, the operation indicator light 10 lights up; in different functional modes, the operation indicator light 10 can be represented by different colors or flashing frequencies, such as a solid red light in heating mode, a solid blue light in blowing mode, and a solid purple light in combination mode, so that users can intuitively understand the working status of the instrument.

[0045] Working principle:

[0046] Press the function button 9 on the top of the upper housing 2. At this time, the operation indicator light 10 will turn red and stay on to indicate to the user that it is currently in heating mode.

[0047] After receiving the heating mode command, the controller 3 supplies power to the ceramic heating element 4, which then begins to generate heat. The heat is transferred to the skin surface through the heating hole 103, initiating heat therapy on the mosquito bite site.

[0048] During the heating process, the temperature measuring module 401 monitors the temperature near the ceramic heating element 4 in real time and feeds the temperature data back to the controller 3. The controller 3 compares the actual temperature with the preset temperature value. If the actual temperature is lower than the preset value, it increases the power supply to the ceramic heating element 4 to raise the temperature; if the actual temperature is higher than the preset value, it reduces the power supply to keep the temperature stable within the preset range, which can be set between 45-51℃.

[0049] To enter the heating and blowing combination mode, press function button 9 twice consecutively to select the heating and blowing combination mode. The operation indicator light 10 will turn solid purple, indicating that the current mode is the combination mode.

[0050] The controller 3 activates the ceramic heating element 4 and the micro air pump 5. The micro air pump 5 blows the heated air around the ceramic heating element 4 onto the skin surface to break down the itch-inducing substances injected into the body after mosquito bites. This mode can improve the comfort of heating to relieve itching, especially to alleviate children's resistance to heating and increase acceptance of use.

[0051] To select individual blower mode, press function button 9 three times consecutively. The operation indicator light 10 will then turn a solid blue, indicating that the system is in blower mode.

[0052] The controller 3 controls the micro air pump 5 to start working. The micro air pump 5 draws in external air through the air inlet 101 via the air inlet nozzle 503. After the air is filtered by the air inlet filter 504, it enters the air inlet pipe 5013 through the connecting pipe 502 and then flows into the annular pipe 5011.

[0053] The air entering the annular pipe 5011 is evenly blown out through multiple outlet pipes 5012 arranged in an annular equidistant array, which function as a fan to cool the user.

[0054] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention's conception through the foregoing teachings or related technical or knowledge.
