[0004] The portable mosquito repellent device has a storage space for accommodating a mosquito repellent solution carrier, and the air diffusion holes directly connect the outside with the storage space, so that when the mosquito repellent device is not used, the dispersing fan is turned off, which easily causes the air diffusion holes to be blocked, affecting normal use, and needs to be improved. Summary of the invention

[0005] In order to improve the problem that the air diffusion holes are easily clogged and thus affect normal use, this technical solution provides a mosquito repeller.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A mosquito repellent, comprising a shell, the shell comprising a base and a box cover arranged on the base, the shell being provided with a storage bin, the storage bin being used to accommodate mosquito repellent material, the end surface of the box cover facing away from the base being provided with a mounting groove, a regulating component being installed in the mounting groove, the regulating component comprising a pressing block, an elastic member and a locking structure, a ventilation groove being provided on the end surface of the pressing block facing the bottom of the mounting groove, an air outlet hole connected to the ventilation groove being provided on a side wall of the pressing block, the bottom of the mounting groove being provided with a ventilation hole, the pressing block sliding relative to the mounting groove, the shell being further provided with a fan, the fan being started to transport the gas in the storage bin toward the air outlet hole;

[0008] When the locking structure is opened, the elastic member enables the pressing block to move away from the bottom of the installation slot and exposes the air outlet hole from the side wall of the installation slot. When the locking structure is locked, the air outlet hole is hidden in the installation slot.

[0009] Through the above technical solution, when the mosquito repeller is in normal use, mosquito repellent material is placed in the storage bin of the shell. The mosquito repellent material is a paste and its main ingredients are citronella and mint. The fan is started to blow the mosquito repellent gas emitted by the mosquito repellent material toward the ventilation hole, and then enters the installation groove and the ventilation groove through the ventilation hole. The locking mechanism is controlled to be opened or locked by pressing the pressing block. When the locking mechanism is opened, the elastic force of the elastic member pushes the pressing block to slide along the installation groove and away from the bottom of the installation groove, so that the locking mechanism is always in the open state, and the pressing block protrudes from the installation groove. Based on this, the air outlet is exposed from the side wall of the installation groove, so that the mosquito repellent gas can flow out through the air outlet smoothly, thereby achieving the effect of repelling mosquitoes.

[0010] When the push block is pressed again, the push block overcomes the elastic force of the elastic part and slides to lock the locking mechanism. The push block is embedded in the installation groove. At this time, the air outlet is hidden in the installation groove, thereby preventing gas from flowing out and preventing external dust or debris from entering and clogging the air outlet, thereby extending the service life of the mosquito repeller and improving performance stability.

[0011] Preferably, the locking structure comprises a locking mechanism and a locking portion, and the locking mechanism and the locking portion are respectively arranged on the bottom of the installation groove and the pressing block in a one-to-one correspondence, and the elastic force of the elastic member makes the locking portion tend to move away from the locking mechanism.

[0012] Through the above technical solution, the locking structure is composed of two parts, namely, a locking mechanism and a locking part. The locking mechanism is arranged on one of the parts of the installation groove bottom or the pressing block, and the locking part is correspondingly arranged on the other part.

[0013] When the locking key is disengaged from the locking mechanism, the locking mechanism is in an open state. When the pressing block is pressed, the pressing block overcomes the elastic force of the elastic member. After the locking key is close to the locking mechanism, the locking mechanism is in a locked state.

[0014] Preferably, the pressing block has a fixing column extending toward the bottom of the mounting groove, the elastic member is sleeved on the fixing column, a fixing hole is opened at the bottom of the mounting groove, the fixing hole is for the fixing column to pass through, one end of the fixing column passing through the fixing hole is connected to a limiting portion, the limiting portion protrudes from the fixing column, and the limiting portion is used to limit the pressing block from detaching from the mounting groove.

[0015] Through the above technical scheme, the elastic part is sleeved on the fixing column of the pressing block, and the fixing column passes through the fixing hole corresponding to the bottom of the mounting groove, so that the two ends of the elastic part are pressed against the bottom of the mounting groove and the bottom of the ventilation groove, and the position of the box cover is relatively stable so that the elastic force can stably act on the pressing block to push it to slide. The limiting part is fixed and protrudes from one end of the fixing column passing through the fixing hole. The cross-sectional area of ​​the limiting part is larger than the channel cross-sectional area of ​​the fixing hole, so that when the fixing column slides, the limiting part contacts the box cover, so as to limit the pressing block from detaching from the mounting groove, thereby improving the installation firmness and the stability of use.

[0016] Preferably, the shell is provided with a control switch, and the control switch is connected to the fan for controlling the start and stop of the fan. One of the limit parts has a trigger key that cooperates with the control switch. When the locking structure is opened, the trigger key triggers the control switch to turn on the fan. When the locking structure is locked, the control switch is disconnected to stop the fan.

[0017] Through the above technical solution, when the locking structure is in the open state, the trigger key will trigger the control switch to make the fan in the on state. When the locking structure is in the locked state, the trigger key will disconnect the control switch to make the fan in the off state. The fan can then be adjusted by the trigger key to achieve synchronous automatic start and stop, thereby achieving consistency in the operation of the fan during use and improving operational convenience.

[0018] Preferably, a mounting plate is further provided in the shell, the mounting plate is connected to the box cover, the material storage bin is located between the base and the mounting plate, and the base and the box cover are detachably connected to expose the material storage bin.

[0019] Through the above technical solution, the mounting plate is fixedly connected to the box cover as an intermediate layer, effectively separating the storage bin and other components on both sides of the mounting plate. The base is removed from the box cover. Since the storage bin is located between the mounting plate and the base, it is convenient to take out the storage bin to add or replace mosquito repellent material, thereby improving the convenience of disassembly, assembly and maintenance of the storage bin.

[0020] Preferably, the storage bin has a bin cover, the bin cover is provided with an air outlet, the fan is located between the mounting plate and the box cover, the mounting plate has an air hole, and the air hole is aligned with the air outlet for gas circulation.

[0021] Through the above technical scheme, the bin cover covers the opening of the storage bin, and the mosquito repellent material is a paste to prevent the mosquito repellent material from scattering or leaking from the storage bin. The position of the air outlet of the storage bin corresponds to the air hole of the mounting plate. The fan is located between the mounting plate and the box cover, and the position of the fan corresponds to the air hole, so that the fan can deliver mosquito repellent gas through the air outlet and the air hole, thereby ensuring the fluidity and circulation efficiency of the gas.

[0022] Preferably, an air guide gap 1 is formed between the box cover and the base, an air guide gap 2 is formed between the base and the mounting plate, and the storage bin is provided with side wind holes, which are formed on the upper and lower end surfaces of the storage bin, and the side wind holes cooperate with air guide gap 1 and air guide gap 2 to provide gas replenishment.

[0023] Through the above technical scheme, the gas outside the shell can enter from the air guide gap one, and enter the space between the mounting plate and the base after passing through the air guide gap two. The side air holes are formed on the upper and lower end surfaces of the storage bin, which increases the inlet size of the airflow entering the storage bin, increases the flow rate of the airflow and enhances the degree of flow, so that the airflow can fully contact the mosquito repellent material and carry the mosquito repellent gas before being stably discharged, avoiding the air pressure resistance generated by the space seal between the mounting plate and the base to affect the gas flow, optimizes the gas flow path, and improves the continuity and stability of the gas flow.

[0024] Preferably, a battery module is installed in the shell, and the shell is also provided with a controller. The battery module is connected to the controller, and the battery module is used to supply power to the fan to make the fan run. The controller is connected to a charging port, and the charging port is used to charge the battery module.

[0025] Through the above technical solution, a charging cable is connected to the charging port of the controller, and the battery module is charged through the charging port. The battery module can store electrical energy for use as a power source.

[0026] Preferably, a working light and a low-power light are provided in the shell, and the working light and the low-power light are connected to the controller for displaying the power level of the battery module.

[0027] Through the above technical solution, the work light and the low-power light feedback different working states. The controller is connected to the work light and the low-power light to display the remaining power status of the battery module. When the battery module is fully charged, the work light comes on, indicating that the mosquito repellent is working normally; when the power is low, the low-power light comes on, indicating that the remaining power of the battery module is insufficient, so as to remind charging, thereby providing users with accurate power prompts to help judge whether the working status is normal and improve convenience.

[0028] Preferably, a temperature sensor is connected inside the shell, and the temperature sensor is connected to the controller. A display is also connected inside the shell, and the display is connected to the controller for displaying the temperature measured by the temperature sensor.

[0029] Through the above technical solution, the temperature sensor is connected to the controller, so that the temperature sensor can sense the temperature inside the shell in real time and transmit the measurement data to the controller. After receiving the temperature data, the controller will perform corresponding processing and transmit the processing result to the display. The temperature value is displayed on the display to present it to the user, which is convenient for intuitively understanding the temperature conditions inside the shell and making corresponding adjustments to improve safety.

The pressing block 41 is provided with a ventilation groove 5, and the ventilation groove 5 is located on the end face of the pressing block 41 facing the bottom of the mounting groove 3. The side wall of the pressing block 41 is penetrated with an air outlet hole 6, and the air outlet hole 6 is located at the upper end of the outer wall of the pressing block 41. There are multiple air outlet holes 6, and each air outlet hole 6 is connected to the ventilation groove 5.

[0045] The locking structure 43 includes a locking mechanism 431 and a locking portion 432. The locking mechanism 431 adopts an elastic self-locking buckle. The elastic self-locking buckle is a prior art that realizes opening and closing transformation by pressing. It has been widely used in trash can door buckles and will not be described in detail here. The locking mechanism 431 and the locking portion 432 are respectively arranged on the bottom of the installation groove 3 and the pressing block 41 in a one-to-one correspondence. In this example, the locking mechanism 431 is arranged at the bottom of the installation groove 3, and the locking portion 432 is arranged on the pressing block 41, the locking mechanism 431 is fixedly installed at the bottom of the installation groove 3, the locking part 432 is fixed at the bottom of the ventilation groove 5 and extends in the direction of the locking mechanism 431. When the locking part 432 is disengaged from the locking mechanism 431, the locking structure 43 is opened.

Alternatively, the locking part 432 can be arranged at the bottom of the installation groove, and the locking mechanism 431 can be arranged on the pressing block 41.

[0046] The pressing block 41 is provided with a plurality of fixing columns 10. This example shows a case where three fixing columns 10 are provided. Each fixing column 10 extends toward the bottom of the mounting groove 3. A plurality of fixing holes 13 are passed through the bottom of the mounting groove 3. The number of the fixing holes 13 is the same as that of the fixing columns 10. Each fixing hole 13 is arranged in a one-to-one correspondence with each fixing column 10. The fixing column 10 passes through the corresponding fixing hole 13. Each fixing column 10 is provided with a limiting portion 14. The limiting portion 14 is located at one end of the fixing column 10 passing through the fixing hole 13. Each limiting portion 14 is fixed to the end face of the corresponding fixing column 10 away from the bottom of the ventilation groove 5 by bolts. The limiting portion 14 is used to limit the fixing column 10 from detaching from the fixing hole 13, so as to limit the pressing block 41 from detaching from the mounting groove 3.

[0047] There are multiple elastic members 42, and the number of elastic members 42 is the same as that of the fixing columns 10.

Each elastic member 42 is sleeved on the corresponding fixing column 10. One end of the elastic member 42 abuts against the bottom of the ventilation groove 5, and the other end of the elastic member 42 abuts against the bottom of the installation groove 3. The elastic force of the elastic member 42 makes the pressing block 41 tend to detach from the installation groove 3, so that the locking portion 432 tends to detach from the locking mechanism 431.

[0048] A mounting plate 17 is also provided in the shell 1, and the mounting plate 17 is located in the box cover 12, and the mounting plate 17 is bolted to the box cover 12.

[0049] A temperature sensor 29 is also connected to the shell 1. The temperature sensor 29 is located in the box cover 12 and is connected to the controller 25. A display 30 is also connected to the shell 1. The display 30 is located in the box cover 12 at the same end close to the temperature sensor 29. The display 30 is connected to the controller 25 for displaying the temperature measured by the temperature sensor 29.

[0050] A working light 27 and a low-power light 28 are provided in the shell 1, and the working light 27 and the low-power light 28 are connected to the controller 25. When the battery module 24 has sufficient power, the controller 25 controls the working light 27 to light up, indicating that the mosquito repellent is working normally. When the power of the battery module 24 is low, the controller 25 controls the low-power light 28 to light up, indicating that the remaining power of the battery module 24 is insufficient. The working light 27 and the low-power light 28 are used together to display the power of the battery module 24.

[0051] The shell 1 is also provided with a fan 9, which is installed between the mounting plate 17 and the box cover 12. The fan 9 is connected to the controller 25. The battery module 24 is used to power the fan 9 to make the fan 9 run. The shell 1 is also provided with a control switch 15, which is located between the box cover 12 and the mounting plate 17.

The trigger key 16 extends toward the control switch 15 and cooperates with the control switch 15 to control the start and stop of the fan 9.

[0052] See also Figure 3 and Figure 4 The shell 1 is provided with a storage bin 2, the opening of the storage bin 2 is directed toward the fan 9, and the storage bin 2 is used to contain mosquito repellent material. The mosquito repellent material can be a paste, and the main components of the paste are citronella and mint. The mosquito repellent material can also be liquid or pellet-shaped mosquito repellent material. When the mosquito repellent material is liquid, the mosquito repeller needs to be fixed vertically. The storage bin 2 is located between the mounting plate 17 and the base 11, and can be detached through the base 11 to expose the storage bin 2. The storage bin 2 is provided with a plurality of side wind holes 23, and the side wind holes 23 are respectively formed on the upper and lower end surfaces of the storage bin 2.

[0053] The storage bin 2 has a bin cover 18, which covers the opening of the storage bin 2. The mounting plate 17 has a plurality of air holes 20 extending therethrough, and the positions of the air holes 20 correspond to the fan 9. The bin cover 18 has a plurality of air outlet holes 19 extending therethrough, and the positions of the air outlet holes 19 correspond to the air holes 20. An air guide gap 1 is formed between the box cover 12 and the base 11, and an air guide gap 2 is formed between the base 11 and the mounting plate 17. The air guide gap 1 is connected to the air guide gap 2. When the base 11 and the mounting plate 17 are in a negative pressure state, external air is replenished into the interior through the air guide gap 1 and the air guide gap 2.

[0054] When the pressing block 41 is pressed, the pressing block 41 overcomes the elastic force of the elastic member 42 and slides. The pressing block 41 compresses the elastic member 42 and embeds it into the mounting groove 3. The air outlet 6 is hidden in the mounting groove 3. The locking portion 432 cooperates with the locking mechanism 431, and the trigger key 16 causes the control switch 15 to be disconnected to shut down the fan 9.

[0055] See also Figure 5 and Figure 6 When the locking portion 432 is disengaged from the locking mechanism 431, the elastic member 42 causes the pressing block 41 to move away from the bottom of the mounting groove 3, and the air outlet 6 is exposed on the side wall of the mounting groove 3. The trigger key 16 causes the control switch 15 to be triggered to turn on the fan 9. The fan 9 is started to transport the gas in the storage bin 2 toward the air outlet 6. The airflow flows along the air guide gap 1 and enters the base 11 from the air guide gap 2, and then enters the storage bin 2 through the side air hole 23. The airflow carries the mosquito repellent gas and passes through the air outlet 19 and the air hole 20 in turn to enter between the mounting plate 17 and the box cover 12. The mosquito repellent gas passes through the ventilation hole 7 and enters the mounting groove 3 and the ventilation groove 5. Based on the exposure of the air outlet 6, the mosquito repellent gas is emitted to the outside of the shell 1 through the air outlet 6 to achieve mosquito repellence.

[0056] The specific working process of this program is as follows:

[0057] The present technical solution is to place mosquito repellent material in the storage bin 2, and to control the matching state between the locking portion 432 and the locking mechanism 431 by pressing the pressing block 41. When the locking portion 432 is disengaged from the locking mechanism 431, the elastic force of the elastic member 42 pushes the pressing block 41 to slide along the mounting groove 3 and away from the bottom of the mounting groove 3, so that the locking portion 432 and the locking mechanism 431 keep a tendency to move away from each other, and the trigger key 16 triggers the control switch 15 to turn on the fan 9, and the fan 9 drives the mosquito repellent gas to flow toward the ventilation hole 7 and then enters the mounting groove 3 and the ventilation groove 5, and the air is discharged. The hole 6 is exposed on the side wall of the mounting groove 3, so that the mosquito repellent gas leaves through the air outlet 6 to achieve the effect of repelling mosquitoes. When the pressing block 41 is pressed, the pressing block 41 overcomes the elastic force of the elastic member 42 and slides toward the locking mechanism 431. The pressing block 41 drives the locking portion 432 to cooperate with the locking mechanism 431, and the control switch 15 is disconnected to shut down the fan 9. The pressing block 41 is embedded in the mounting groove 3. At this time, the air outlet 6 is hidden in the mounting groove 3, thereby preventing the gas from flowing out, preventing external dust or debris from entering and clogging the air outlet 6, extending the service life of the mosquito repellent, and thereby improving performance stability.
