Description

Technical Field

[0001] The utility model relates to the technical field of mosquito repellent, in particular to a multifunctional mosquito repellent device. Background Art

[0002] In life, especially in summer to achieve the effect of mosquito repellent, people have invented electric mosquito repellers, which make the medicine volatilize by using the electric mosquito repellers to achieve the mosquito repellent effect.

[0003] The traditional electric mosquito repeller includes a housing, and an electric heating part is arranged inside the housing. The electric heating part is mainly composed of a circuit board, a heating element and a heat transfer sheet. And a placement groove for placing a mosquito repellent sheet is arranged on the surface of the housing. The mosquito repellent sheet is placed in the placement groove. After the circuit works, the heating element generates a certain temperature to make the effective medicine of the tablet placed on the heat transfer sheet volatilize into the indoor space to achieve the effect of mosquito repellent. Until the mosquito repellent sheet is used up, the mosquito repellent sheet can be taken out of the placement groove and replaced with another one to continue using.

[0004] However, such an electric mosquito repeller still has some problems. It has only one mosquito repellent method and relatively single functions. It only heats the mosquito repellent sheet to achieve mosquito repellent, and the mosquito repellent effect is average. Moreover, it is inconvenient to take and place the mosquito repellent sheet. Summary of the Invention

[0005] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a multifunctional mosquito repellent device, which is convenient for replacing the mosquito repellent sheet, adds a buzzer, has multiple mosquito repellent methods to choose from, no longer has single functions, and has a good mosquito repellent effect.

[0006] The technical solution of the utility model: A multifunctional mosquito repellent device includes a housing and a heating component for heating a mosquito repellent sheet. A partition is arranged inside the housing to form an upper installation area and a lower installation area. The heating component is arranged in the upper installation area. The heating component includes two relatively arranged heating sheets, and an installation channel for inserting the mosquito repellent sheet is formed between the two heating sheets. A plurality of penetrating first ventilation holes are arranged on the two heating sheets. The housing is correspondingly provided with an opening for the mosquito repellent sheet to enter and exit the installation channel and a plurality of second ventilation holes. A circuit board and a buzzer are arranged in the lower installation area. A plurality of through holes are arranged on the housing corresponding to the position of the buzzer. Both heating sheets are connected to the circuit board. The circuit board is also provided with a first drive switch for driving the heating sheet to work and a second drive switch for driving the buzzer to work.

[0007] With the above technical solution, the mosquito repellent sheet is convenient to replace. It can be pushed from the opening on one side of the outer shell to the opening on the other side, facilitating the taking and placing of the mosquito repellent sheet. The two heating sheets are located on both sides of the mosquito repellent sheet and can be in full contact with the mosquito repellent sheet, improving the heating efficiency and enabling the mosquito repellent components in the mosquito repellent sheet to evaporate fully. The arrangement of the first ventilation holes and the second ventilation holes allows the smell of the mosquito repellent sheet to be discharged outside the upper installation area. At the same time, the buzzer can emit ultrasonic waves, simulating the sound frequency of male mosquitoes to achieve the purpose of mosquito repellent. Since the present utility model uses dual mosquito repellent methods of ultrasonic waves and drugs, the mosquito repellent effect is obvious, making up for the shortcomings of single function and unsatisfactory effect of mosquito repellent devices in the market.

The mosquito repellent sheet is convenient to replace and can be pushed from one side opening 13 of the housing 1 to the other side opening 13, facilitating the taking and placing of the mosquito repellent sheet. The two heating sheets 21 are located on both sides of the mosquito repellent sheet and can be in full contact with the mosquito repellent sheet. The heating sheet 21 contacts the wide surface of the mosquito repellent sheet, and the wide surface refers to the surface with the largest area of the mosquito repellent sheet. The heating sheet 21 adopts an MCH ceramic sheet or a PCT heating sheet 21 to improve the heating efficiency, so that the mosquito repellent components in the mosquito repellent sheet can be fully evaporated. The setting of the first ventilation holes 211 and the second ventilation holes 14 enables the smell of the mosquito repellent sheet to be discharged outside the upper installation area 11. At the same time, the buzzer can emit ultrasonic waves to simulate the male mosquito's vocal frequency to achieve the purpose of mosquito repellent. Due to the dual mosquito repellent effects of ultrasonic waves and drugs, the mosquito repellent effect is obvious, making up for the shortcomings of single function and unsatisfactory effect of mosquito repellent devices in the market. A protruding accommodation cavity 19 is provided on the housing 1. The buzzer 8 is located in the accommodation cavity 19, and a baffle detachably connected to the housing is provided at the position of the accommodation cavity 19.
