Description

Technical Field

[0001] The invention relates to the technical field of mosquito repellent, in particular to an ultrasonic atomizing mosquito repellent device. Background Art

[0002] Currently, the main dispersion technologies for existing mosquito repellent products include ultrasonic atomization and thermal radiation. Both dispersion methods have certain limitations or disadvantages.

In addition, it is easy to adhere to the inner wall of the cavity of the device during the dispersion process, affecting the effective volatilization of the liquid medicine. As for heating mosquito repellents, although the gas particles produced after heating are smaller, the heating element requires a certain amount of time to heat up, and it also takes a certain amount of time for the liquid medicine to directly change from liquid to gas, resulting in a longer time for the medicine to take effect.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-9 The present invention provides a technical solution: an ultrasonic atomizing mosquito repellent, comprising an upper shell 1, a lower shell 2, a base 3, an ultrasonic atomizer 4 and a heater 5, wherein the upper shell 1 is fixed to the top of the lower shell 2, and the interiors of the upper shell 1 and the lower shell 2 are connected, the lower shell 2 is placed on the base 3, the ultrasonic atomizer 4 is located inside the lower shell 2 and placed on the base 3, the heater 5 is fixed inside the upper shell 1, and the top of the upper shell 1 is provided with a first through hole 6 for volatilization of mosquito repellent liquid.

[0028] When the mosquito repellent is working, mosquito repellent liquid is added into the ultrasonic atomizer 4, and the mosquito repellent liquid is atomized by the ultrasonic atomizer 4. The ultrasonic atomizer 4 adopts the existing ultrasonic ultrasonic atomizer 4, which is often used as a humidifier and a liquid medicine ultrasonic atomizer 4. The atomized mosquito repellent liquid is heated by the heater 5, so that the atomized mosquito repellent liquid is heated into steam with smaller molecules. The ultrasonic atomization and heating are combined to ensure that the effective ingredients have a wide diffusion range. The liquid medicine is first atomized into mist by ultrasonic atomization. The larger particles of the atomized medicine components encounter the heater 5 and are heated during the upward volatilization process. The atomized medicine is further heated and vaporized. On the one hand, the vaporization time of the medicine liquid is greatly shortened, making the medicine take effect faster. On the other hand, it avoids the atomized medicine from adhering to the inner wall of the container and causing medicine waste. The mosquito repellent performance of the mosquito repellent product is greatly improved.

[0029] The heater 5 includes an adjusting shaft 7, a heating device 8 and a power transmission device 9. There are multiple heating devices 8, and the multiple heating devices 8 are vertically distributed on the adjusting shaft 7. The upper part of the adjusting shaft 7 is rotatably connected to the top of the upper shell 1 through a bearing. The power transmission device 9 is used to electrically connect the multiple heating devices 8 to the power supply.

[0030] The heating device 8 includes a heating plate 11 provided with a second through hole 10, a limit bar 12, a heating tube 13, a driving member 14 and a switch device 15. The heating plate 11 is connected to the adjusting shaft 7 through the driving member 14. The heating tube 13 is fixed to the bottom of the heating plate 11. The two ends of the heating tube 13 are respectively provided with a first electrode sheet 16. The switch devices 15 on the multiple heating devices 8 are fixed on the inner wall of the upper shell 1 at a certain angle with the adjusting shaft 7 as the rotation axis. The switch device 15 is used to limit the rotation position of the heating plate 11 and control the circuit of the external power supply to power the heating tube 13. The limit bar 12 is located on one side of the heating plate 11 and fixed on the inside of the upper shell 1. The limit bars 12 on the multiple heating devices 8 are located on the same vertical line.

[0031] The driving member 14 includes a driving cylinder 17, a U-shaped rod 18, a driving plate 19 and a limiting member 20. The driving cylinder 17 is fixedly sleeved on the adjusting shaft 7. The upper and lower parts of the driving cylinder 17 are provided with annular grooves 21. There are two U-shaped rods 18, and the two U-shaped rods 18 are respectively slidably sleeved on the annular grooves 21. Both ends of the U-shaped rod 18 are fixed to the driving plate 19. The end of the heating plate 11 close to the adjusting shaft 7 is fixed to the driving plate 19. The limiting member 20 is used to limit the rotation of the heating plate 11 relative to the adjusting shaft 7.

[0032] The limiting member 20 includes a limiting spring 22, a driving sleeve 23, a limiting plate 24 and a limiting shaft 25. The driving sleeve 23 is fixedly sleeved on the middle part of the driving cylinder 17. A plurality of anti-slip teeth 26 are fixed on the outer side of the driving sleeve 23. The limiting shaft 25 passes through the driving plate 19 and is slidably connected to the driving plate 19. One end of the limiting shaft 25 is against the anti-slip teeth 26, and the other end is fixed to the limiting plate 24. One end of the limiting spring 22 is fixed to the limiting plate 24, and the other end is fixed to the driving plate 19.

[0033] The switch device 15 includes a second electrode sheet 27, an insulating plate 28, a wire 29, a buffer spring 30, a buffer plate 31 and a fixed plate 32. Two second electrode sheets 27 are provided, and the two second electrode sheets 27 correspond to the first electrode sheets 16 at both ends of the heating tube 13 respectively. The two second electrode sheets 27 are respectively fixed to the two ends of the insulating plate 28, one end of the buffer plate 31 is fixed to the insulating plate 28, the two ends of the buffer spring 30 are respectively fixed to the buffer plate 31 and the fixed plate 32, and the fixed plate 32 is fixed to the inner wall of the upper shell 1. The second electrode sheet 27 is fixedly connected to the wire 29. A strip opening 33 is provided at a position corresponding to the wire 29 on the upper shell 1. The wire 29 passes through the strip opening 33 and is electrically connected to the power transmission device 9.

[0034] The power transmission device 9 includes a circuit board 34 and a power line 35. The circuit board 34 is provided with a live wire terminal, a neutral wire terminal and a ground wire terminal. The wires 29 at both ends of the corresponding heating tube 13 are electrically connected to the live wire terminal and the neutral wire terminal on the circuit board 34 respectively. The live wire terminal, the neutral wire terminal and the ground wire terminal on the circuit board 34 are respectively connected to the external power supply through the power line 35.

[0035] During operation, the atomization speed of the ultrasonic atomizer 4 can be adjusted according to the environment, and the number of working heating devices 8 and the coverage area can be further adjusted to optimize the mosquito repellent effect. The minimum heating power of the heater 5 is when only one heating device 8 is working. At this time, multiple heating devices 8 are located on the same vertical line. When the number of working heating devices 8 is adjusted, the multiple heating devices 8 can be driven to rotate synchronously by rotating the adjustment shaft 7. When the multiple heating devices 8 rotate synchronously, they contact the corresponding switch devices 15 one by one. After contact, the first electrode pieces 16 at both ends of the heating tube 13 contact the two second electrode pieces 27 on the switch device 15, and the heating tube 13 can be energized.

[0036] By adjusting the rotation angle of the adjustment shaft 7, the number of heating tubes 13 on the multiple heating devices 8 that are energized can be controlled, thereby achieving the purpose of controlling the operation of different numbers of heating devices 8.

[0037] After the first electrode sheet 16 and the second electrode sheet 27 come into contact, the limiting shaft 25 on the corresponding heating device 8 slides relative to the driving sleeve 23 under the action of the rotational force of the adjustment shaft 7. At this time, the heating tube 13 is energized and the heating plate 11 no longer rotates, which does not affect the rotation of the next group of heating devices 8.

[0038] When the number of heating devices 8 is controlled to change from more to less, the adjustment shaft 7 can be rotated in the opposite direction so that the sides of the multiple heating plates 11 respectively abut against the limit bars 12. At this time, the multiple heating plates 11 are located on the same vertical line.

[0039] The heating tube 13 can heat the heating plate 11 and heat the air in the upper shell 1 at the same time, so that the atomized mosquito repellent liquid can be heated and vaporized.

[0040] The end of the limiting shaft 25 that abuts against the anti-slip teeth 26 is an arc-shaped structure, which reduces the wear of the limiting shaft 25 on the anti-slip teeth 26.

[0041] There are six heating devices 8 , and the heating plates 11 are fan-shaped with a central angle of 60 degrees, so that the heating plates 11 can cover the interior of the upper shell 1 360 degrees.

[0042] A knob 36 is fixed to the top end of the adjusting shaft 7 to facilitate the rotation of the adjusting shaft 7 .
