Description

Technical Field

[0001] This application relates to the technical field of daily necessities, and in particular to an electric mosquito repellent with lighting function. Background Technology

[0002] Mosquitoes are common pests in daily life. They can easily carry viruses that spread diseases, and their presence at night can disrupt sleep quality. Therefore, people desire an effective mosquito control device. Currently, electric mosquito repellents are widely used. These devices work by electrically heating the mosquito repellent liquid. During heating, the liquid releases repellent gases that poison the mosquito's nervous system, thus killing it.

[0003] However, existing electric mosquito repellents have limited functionality, with the only function being to electrically heat the mosquito repellent liquid. This makes them less practical and leaves room for improvement. Summary of the Invention

[0004] In order to improve the practicality and enrich the functions of electric mosquito repellents, this application provides an electric mosquito repellent with lighting function.

[0005] The electric mosquito repellent device and circuit with lighting function provided in this application adopt the following technical solution:

[0006] An electric mosquito repellent with lighting function and its circuitry include an upper housing, a lower housing, a mosquito repellent component, a ring-shaped light strip, and a snap-fit ​​power-on component. The top of the upper housing has an air outlet, and the bottom of the upper housing has a recessed mounting groove facing inwards. The top of the lower housing has a recessed receiving groove facing inwards. The mosquito repellent component is disposed within the receiving groove and threadedly connected to the mounting groove. A control circuit board is disposed within the upper housing, and the control circuit board includes a heater and a battery. The battery provides operating voltage to the electric mosquito repellent, and the heater heats the mosquito repellent component. The ring-shaped light strip surrounds the outer wall of the receiving groove. The snap-fit ​​power-on component enables the upper and lower housings to snap together and simultaneously allows the battery to power the ring-shaped light strip. A light switch button is disposed on the outer wall of the upper housing, and the light switch button is electrically connected to the control circuit board.

[0007] By adopting the above technical solution, when using the electric mosquito repellent, the mosquito repellent component is placed in the receiving groove of the lower shell and screwed into the mounting groove. The power-on component is then engaged to connect the lower shell to the upper shell, simultaneously establishing an electrical connection between the battery and the ring light strip. The battery powers the ring light strip and provides operating voltage to the electric mosquito repellent, activating the heater on the control circuit board inside the upper shell. The heater heats the mosquito repellent component, causing the mosquito repellent liquid inside to evaporate into mosquito-repellent gas due to capillary action and increased temperature. This gas flows out into the room through the air outlet of the upper shell, achieving the mosquito repellent function. By pressing the light switch button on the outer wall of the upper shell, the ring light strip inside the lower shell is powered on and illuminated, thus providing the electric mosquito repellent with a lighting function. The outer wall of the receiving groove diffuses the light emitted by the ring light strip, improving its illumination effect. Therefore, the electric mosquito repellent provides indoor lighting while repelling mosquitoes, enriching its functionality and improving its practicality.

[0008] Optionally, the snap-fit ​​power-on assembly includes a snap-fit ​​groove disposed at the bottom of the upper housing and a snap-fit ​​protrusion disposed in the receiving groove. The snap-fit ​​groove includes an inlet portion and a limiting portion. The inlet portion communicates with the limiting portion. The inlet portion is used to slide with the snap-fit ​​protrusion, and the limiting portion is used to snap-fit ​​with the snap-fit ​​protrusion. The bottom groove of the limiting portion is provided with a snap-fit ​​recess. The snap-fit ​​protrusion is provided with a protrusion adapted to the snap-fit ​​recess. When the upper housing and the lower housing are snap-fitted together, the protrusion on the snap-fit ​​protrusion abuts against the snap-fit ​​recess.

[0009] By adopting the above technical solution, when the lower housing is snapped onto the upper housing, the snapping protrusion of the receiving groove is located in the guide part of the snapping groove of the upper housing. The user rotates the lower housing, causing the snapping protrusion to slide in the guide part in the direction close to the limiting part until the snapping protrusion is located at the limiting part of the snapping groove. The protrusion on the snapping protrusion engages with the snapping recess of the limiting part, so that the snapping protrusion is snapped and fixed with the snapping groove, thereby enabling the lower housing to be snapped onto the upper housing.

[0010] Optionally, the snap-fit ​​power-on component further includes a conductive plug, one end of which is electrically connected to the battery. The top of the lower housing is provided with an electrical insertion hole, and the top of the receiving groove is provided with a positioning groove. The bottom of the positioning groove includes a planar area and an insertion hole area. The electrical insertion hole is located in the insertion hole area at the bottom of the positioning groove. The other end of the conductive plug is inserted into the electrical insertion hole. The conductive plug supplies power to the ring-shaped light strip through the electrical insertion hole. When the conductive plug is located in the planar area at the bottom of the positioning groove, the snap-fit ​​protrusion is located in the guide portion of the snap-fit ​​groove. When the conductive plug moves to the insertion hole area at the bottom of the positioning groove, the snap-fit ​​protrusion is located in the limiting portion of the snap-fit ​​groove.

[0011] By adopting the above technical solution, when the lower housing needs to be snapped onto the upper housing, the conductive plug inside the upper housing is placed in the flat area at the bottom of the positioning groove, so that the snapping protrusion of the lower housing is located in the guide part of the snapping groove of the upper housing, thereby making it easier for the user to snap the lower housing onto the upper housing. As the user rotates the lower housing, the conductive plug moves to the insertion hole area at the bottom of the positioning groove, and the snapping protrusion of the lower housing is located at the limiting part of the snapping groove of the upper housing. The conductive plug is inserted into the electrical insertion hole in the insertion hole area at the bottom of the positioning groove. After the snapping of the lower housing and the upper housing is completed, the conductive plug is inserted into the electrical insertion hole, thereby realizing the power supply to the ring light strip of the lower housing.

[0012] Optionally, the outer wall of the upper housing is provided with a timer button and several indicator lights. The timer button and several indicator lights are electrically connected to the control circuit board. Several indicator lights are arranged on one side of the timer button. The indicator lights are used to indicate the timer status and the lighting status of the electric mosquito repellent.

[0013] By adopting the above technical solution, by pressing the timer button on the outer wall of the upper housing, the control circuit board inside the upper housing sets the heating time of the heating plate of the electric mosquito repellent according to the pressing of the timer button. At the same time, the indicator lights on the outer wall of the upper housing light up the corresponding indicator lights according to the timer status of the electric mosquito repellent. Users can understand the timer status of the electric mosquito repellent by looking at the indicator lights. When the battery power in the electric mosquito repellent is too low, the indicator light will flash, thus reminding the user that the battery power of the electric mosquito repellent is too low.

[0014] Optionally, the control circuit board is electrically connected to an electric mosquito repellent control circuit. The electric mosquito repellent control circuit includes an MCU control module, a battery protection module, a function output module, a boost module, and a charging module. A charging interface is provided on the outer wall of the upper housing, and the charging interface is electrically connected to the battery. One end of the charging module is electrically connected to the battery, and the other end of the charging module is electrically connected to both the MCU control module and the boost module. The charging module is used to charge the battery and output charging data to the boost module and the MCU main control module in real time. The other end of the boost module is electrically connected to the MCU control module. The boost module is used to adjust the charging data according to the battery charging process. The battery protection module is electrically connected to the battery to protect against changes in electrical data. One end of the MCU control module is electrically connected to the light switch button and the timer button, respectively, and the other end of the MCU control module is electrically connected to the indicator light and the function output module, respectively. The MCU control module is used to generate control signals according to the pressed state of the light switch button or the timer button, and output them to the indicator light and the function output module. The output end of the function output module is coupled to the heater and the ring light strip, respectively. When the function output module receives the control signal, it outputs a start signal to the heater and the ring light strip. When the heater and the ring light strip receive the start signal, they are both powered on and start working.

[0015] By adopting the above technical solution, the electric mosquito repellent is powered by a battery. The battery protection module on the control circuit board provides real-time protection for the battery, enabling a more stable supply of operating voltage. When the electric mosquito repellent is activated, the MCU control module outputs a control signal to the function output module. Upon receiving the control signal, the function output module outputs a start signal to the heater, which then powers on and heats the core rod. When the battery is low, the user can plug in a charging cable to charge the electric mosquito repellent. The charging module on the control circuit board charges the battery, and the MCU control module and boost module protect the battery during the charging process. This effectively prevents battery overcharging and damage. When the user presses the light switch button, the MCU control module generates a control signal based on the button press and outputs it to the function output module. The function output module then outputs a start signal to the ring light strip, illuminating it and giving the electric mosquito repellent its lighting function. When the user presses the timer button, the MCU control module generates a control signal based on the button press and outputs it to the indicator light, illuminating it to show the timer setting. Simultaneously, the MCU control module sets the heater's operating time based on the timer setting. When the preset countdown ends, the heater is powered off and stops working, thus achieving the timed shutdown function of the electric mosquito repellent.

[0016] Optionally, the charging module includes a charging chip U1 and a USB socket. The USB socket is electrically connected to the charging interface and is also coupled to the charging chip U1. The power supply terminal of the charging chip U1 is coupled to the battery, and the output terminal of the charging chip U1 is coupled to the MCU control module.

[0017] By adopting the above technical solution, when a charging cable is plugged into the charging interface, the battery is charged through the USB socket. The charging chip U1 outputs the battery charging information to the MCU control module in real time through the output terminal, thereby realizing the function of charging the battery of the electric mosquito repellent.

[0018] Optionally, the boost module includes a boost chip U2, which includes a power input terminal and an enable control terminal. The power input terminal of the boost chip U2 is coupled to a battery, and the enable control terminal of the boost chip U2 is coupled to an MCU control module.

[0019] By adopting the above technical solution, the MCU control module inputs the battery charging data into the boost chip U2 through the enable control terminal of the boost chip U2. The boost chip U2 can protect the battery charging process in real time according to the battery charging data, effectively preventing overcharging and overheating during battery charging, and realizing overcharging and overheating protection for battery charging.

[0020] Optionally, the MCU control module includes a control chip U3, which includes an indicator light control terminal, a button control terminal, a charging control terminal, and a control output terminal. The indicator light control terminal of the control chip U3 is electrically connected to the indicator light, the button control terminal of the control chip U3 is electrically connected to the light switch button and the timer button, the charging control terminal of the control chip U3 is electrically connected to the charging chip U1 and the boost chip U2, and the control output terminal of the control chip U3 is electrically connected to the function output module.

[0021] By adopting the above technical solution, when the electric mosquito repellent is powered on and started, the control chip U3 outputs a control signal to the function output module through the control output terminal, realizing the start function of the control function output module. The button control terminal of the control chip U3 detects the pressing status of the light switch button and generates a control signal, which is output to the function output module through the control output terminal of the control chip U3. The button control terminal of the control chip U3 can also detect the pressing status of the timer button. The control signal is output to the indicator light through the indicator light control terminal of the control chip U3, so that the indicator light is powered on and lit. At the same time, the control signal is output to the function output module through the control output terminal to realize the timed shutdown function of the heater. During the charging process of the electric mosquito repellent, the charging control terminal of the control chip U3 is used to input the battery charging data to realize the charging protection control function of the electric mosquito repellent.

[0022] Optionally, the functional output module includes a light output submodule and a heater output submodule. The input terminal of the light output submodule is coupled to the control chip U3, and the output terminal of the light output submodule is coupled to the ring light strip.

The gate of the first MOSFET Q1 is connected in series with a first resistor R1 and is electrically connected to the control output terminal of the control chip U3. The source of the first MOSFET Q1 is connected in series with a second resistor R2. The other end of the second resistor R2 is coupled to the gate of the first MOSFET Q1. The connection node between the source of the first MOSFET Q1 and the second resistor R2 is grounded. The drain of the first MOSFET Q1 is electrically connected to the ring light strip.

[0023] By adopting the above technical solution, when the control output terminal of the control chip U3 outputs a control signal, the gate of the first MOS transistor Q1 receives the control signal, and the first MOS transistor Q1 is in a conducting state, thereby energizing and lighting the ring light strip, realizing the function of lighting the ring light strip, and thus enabling the electric heating mosquito repellent to have a lighting function.

[0024] Optionally, the input terminal of the heater output submodule is coupled to the control output terminal of the control chip U3, and the output terminal of the heater output submodule is coupled to the heater. The heater output submodule includes a second MOS transistor Q2. The gate of the second MOS transistor Q2 is connected in series with a fourth resistor R4 and then coupled to the control output terminal of the control chip U3. The source of the second MOS transistor Q2 is electrically connected to a third resistor R3. The other end of the third resistor R3 is coupled to the gate of the second MOS transistor Q2. The connection node between the third resistor R3 and the source of the second MOS transistor Q2 is grounded. The drain of the second MOS transistor Q2 is electrically connected to the heater.

[0025] By adopting the above technical solution, when the control output terminal of the control chip U3 outputs a control signal, the gate of the second MOS transistor Q2 receives the control signal and the second MOS transistor Q2 is turned on, thereby powering on the heater to start the heating function, thereby heating the core rod in the mosquito repellent component and activating the mosquito repellent function.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By installing a ring-shaped light strip inside the lower housing of the electric mosquito repellent, after the electric mosquito repellent is connected to the power supply, the heater on the control circuit board inside the upper housing is activated. The heater heats the core rod, and after the core rod is heated, the mosquito repellent liquid in the mosquito repellent component is absorbed to the top of the core rod by capillary action. As the temperature of the core rod rises, the mosquito repellent liquid evaporates, and the evaporated mosquito repellent gas flows out into the room through the air outlet of the upper housing, thus realizing the mosquito repellent function. Pressing the light switch button on the outer wall of the upper housing will turn on the ring-shaped light strip inside the lower housing, thereby enabling the electric mosquito repellent to have an illumination function. The electric mosquito repellent can provide indoor lighting while repelling mosquitoes, enriching the functionality of the electric mosquito repellent and improving its practicality.

[0028] 2. When the lower housing is snapped onto the upper housing, the snapping protrusion of the receiving groove is located in the guide part of the snapping groove of the upper housing. The user rotates the lower housing, causing the snapping protrusion to slide in the guide part in the direction close to the limiting part until the snapping protrusion is located at the limiting part of the snapping groove. The protrusion on the snapping protrusion engages with the snapping recess of the limiting part, so that the snapping protrusion is snapped and fixed with the snapping groove, thereby enabling the lower housing to be snapped onto the upper housing.

[0029] 3. By pressing the timer button on the outer wall of the upper housing, the control circuit board inside the upper housing sets the heating time for the heating plate of the electric mosquito repellent according to the timer button being pressed. At the same time, the indicator lights on the outer wall of the upper housing light up the corresponding indicator lights according to the timer status of the electric mosquito repellent. Users can check the timer status of the electric mosquito repellent by looking at the indicator lights. When the battery power in the electric mosquito repellent is too low, the indicator light will flash to remind the user that the battery power of the electric mosquito repellent is too low.

[0030] 4. When the lower housing needs to be snapped onto the upper housing, place the conductive plug inside the upper housing in the flat area at the bottom of the positioning groove, so that the snapping protrusion of the lower housing is located in the guide part of the snapping groove of the upper housing, making it easier for the user to snap the lower housing onto the upper housing. As the user rotates the lower housing, the conductive plug moves to the insertion hole area at the bottom of the positioning groove, and the snapping protrusion of the lower housing is located in the limiting part of the snapping groove of the upper housing. The conductive plug is inserted into the electrical insertion hole in the insertion hole area at the bottom of the positioning groove. After the lower housing and the upper housing are snapped together, the conductive plug is inserted into the electrical insertion hole, thereby enabling power supply to the ring light strip of the lower housing.

[0045] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0046] This application discloses an electric mosquito repellent with lighting function.

[0047] Reference Figure 1 and Figure 2An electric mosquito repellent with lighting function and its circuit include an upper housing 3 and a lower housing 2.

When the countdown of the electric mosquito repellent ends, the indicator light 6 will turn off.

[0049] Several heat dissipation holes 33 are provided on the outer wall of the upper housing 3 near the lower housing 2. The heat dissipation holes 33 are positioned opposite each other on the outer wall of the upper housing 3. A charging interface 34 is provided on the outer wall of the upper housing 3 for connecting a charging cable. Specifically, when the electric mosquito repellent is in a low battery state, the fourth indicator light 6 illuminates in a red light state. The user can then plug the charging cable into the charging interface 34 to charge the electric mosquito repellent. When the electric mosquito repellent is fully charged, the fourth indicator light 6 illuminates in a green light state, and the electric mosquito repellent can work normally.

An exhaust fan 10 is also installed inside the upper housing 3. The exhaust fan 10 is electrically connected to the control circuit board and is installed at the air outlet 32 ​​at the top of the upper housing 3.

[0051] The lower housing 2 is detachably mounted to the bottom of the upper housing 3 via a snap-fit ​​power-on assembly 16. The snap-fit ​​power-on assembly 16 also enables the battery 7 to power the annular light strip 9. The snap-fit ​​power-on assembly 16 includes a snap-fit ​​groove 161 at the bottom of the upper housing 3, a snap-fit ​​protrusion 162 in the receiving groove 21, and a conductive plug 163.

An electrical socket 17 is provided at the top of the lower housing 2, and the other end of the conductive plug 163 is inserted into the electrical socket 17, which is electrically connected to the annular light strip 9. The snap-fit ​​groove 161 includes an inlet portion 1611 and a limiting portion 1612. The inlet portion 1611 communicates with the limiting portion 1612. Used for sliding engagement with the snap-fit ​​protrusion 162. When the snap-fit ​​protrusion 162 is located in the guide portion 1611 of the snap-fit ​​groove 161, the snap-fit ​​protrusion 162 can slide horizontally within the snap-fit ​​groove 161. The limiting portion 1612 is used for snap-fit ​​engagement with the snap-fit ​​protrusion 162. The bottom groove of the limiting portion 1612 is provided with a snap-fit ​​recess 1613. The snap-fit ​​protrusion 162 is provided with a protrusion that matches the snap-fit ​​recess 1613. When the protrusion on the snap-fit ​​protrusion 162 abuts against the snap-fit ​​recess 1613, the lower housing 2 is snapped into the upper housing 3.

When the conductive plug 163 moves... When the lower housing 2 moves to the insertion hole area 222 at the bottom of the positioning groove 22, the snap-fit ​​protrusion 162 is located at the limiting part 1612 of the snap-fit ​​groove 161. When the conductive plug 163 is inserted into the electrical socket 17, the snap-fit ​​protrusion 162 of the lower housing 2 is located at the limiting part 1612 of the snap-fit ​​groove 161 of the upper housing 3, and the conductive plug 163 is inserted into the electrical socket 17 of the insertion hole area 222 at the bottom of the positioning groove 22, thus completing the snap-fit ​​between the lower housing 2 and the upper housing 3.

[0053] Specifically, after the heater 8 is powered on, it heats the core rod. The heated core rod causes the mosquito repellent liquid in the mosquito repellent component 1 to be absorbed to the top of the core rod by capillary action. As the temperature of the core rod rises, the mosquito repellent liquid evaporates into mosquito repellent gas. The exhaust fan 10 in the upper housing 3 is powered on and starts to quickly exhaust the mosquito repellent gas in the upper housing 3 into the room, thus realizing the mosquito repellent function. The conductive plug 163 is plugged into the electrical socket 17, and the electrical energy of the battery 7 is transmitted to the ring light strip 9 through the conductive plug 163, so that the ring light strip 9 is powered on and lit, thereby enabling the electric heating mosquito repellent to have an illumination function.

[0054] Reference Figure 1 and Figure 3 The timer button 4, indicator light 6, and light switch button 5 are all electrically connected to the control circuit board. Specifically, when the user presses the light switch button 5, the annular light strip 9 inside the lower housing 2 is powered on and illuminated. In this embodiment, the lower housing 2 is a soft light shield. After the annular light strip 9 is powered on and illuminated, the interior of the lower housing 2 is illuminated, thus enabling the electric mosquito repellent to have an illumination function.

Turn on the electric mosquito repellent, and the battery 7 provides the working voltage to the electric mosquito repellent. The heater 8 heats the core rod. After the core rod is heated, the mosquito repellent liquid in the mosquito repellent component 1 is absorbed to the top of the core rod by capillary action. As the temperature of the core rod rises, the mosquito repellent liquid evaporates and releases mosquito repellent gas. The exhaust fan 10 in the upper housing 3 is turned on and starts to quickly exhaust the mosquito repellent gas in the upper housing 3 into the room, thus realizing the mosquito repellent function.

After the ring light strip 9 is powered on and illuminated, the interior of the lower housing 2 is illuminated, thus enabling the electric mosquito repellent to have an illumination function.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
