Embodiment 1
[0038] Such as figure 2 Shown is a structural block diagram of Embodiment 1 of the present invention.
[0039] In a preferred embodiment, the ultrasonic mosquito repellent device 2 of a functional schoolbag is a frequency conversion ultrasonic mosquito repellent device 20, which includes an ultrasonic signal generator 21, a central controller 22, an electronic frequency conversion circuit 23, a high frequency Speaker 24 and infrared sensing module 25.
[0040] Furthermore, the ultrasonic signal generator 21 includes a first ultrasonic generator 210 simulating the vibration frequency of male mosquito wings and a second ultrasonic generator 211 simulating the sound wave frequency of natural enemies of mosquitoes.
[0041] As preferably, the ultrasonic frequency range of the simulated male mosquito wing vibration frequency is 21 ~ 23KH Z , the ultrasonic frequency range of simulating the sound frequency of mosquito natural enemies is 2.6~2.8 KH Z .
[0042] Further, the pow...
Embodiment 2
[0050] Such as image 3 The structural block diagram of embodiment 2 among the shown present invention. For the parts in this embodiment that are the same as in Embodiment 1, please refer to the content disclosed in Embodiment 1 for understanding, and no repeated description will be made here.
[0051] see image 3 The difference between this embodiment and Embodiment 1 is that the ultrasonic mosquito repellent device for a functional schoolbag is a software program type ultrasonic mosquito repellent device 20', which includes an ultrasonic frequency storage unit 21', a central control unit 22', Ultrasonic oscillator 24' and infrared sensing module 25.
[0052] Specifically, the ultrasonic frequency storage unit 21' is composed of a first storage unit 210' and a second storage unit 211', the first storage unit 210' is used to preset and store the vibration frequency of the simulated male mosquito wing The frequency of the ultrasonic waves; the second storage unit 211' is us...

Abstract
A functional schoolbag comprises a schoolbag main body and a power supply device, wherein a mosquito dispelling device is further arranged on the schoolbag main body and is connected with the power supply device. The functional schoolbag not only has all the functions of a traditional schoolbag, but also has a mosquito dispelling function. The integration of the schoolbag and the mosquito dispelling device is realized, and the functions of accommodating objects and dispelling mosquitoes are simultaneously realized without influencing the physical health of a user, so that a work and learning environment which is free of mosquito invasion is provided for the user. As the used mosquito dispelling device is an environment-friendly variable-frequency ultrasonic mosquito dispelling device or an environment-friendly software programmable ultrasonic mosquito dispelling device, the mosquito dispelling device is sanitary and pollution-free, does not have any toxic or side effects on the human body, is convenient to carry, and does not occupy private space. The use feeling of a user is greatly enhanced, and mosquito invasion is avoided during work and learning, so that the working and learning efficiency is improved, and multiple effects are realized.
Description
technical field [0001] The invention relates to a school bag, more specifically, to a functional school bag. Background technique [0002] School bags can be used to accommodate books and other items, but the existing school bags have single functions and cannot meet the needs of users. In order to solve this problem, some solutions have been proposed in the prior art. [0003] The Chinese utility model patent published on August 29, 2012, with the publication number 202396761U, discloses a solar charging schoolbag. The schoolbag is provided with a charging board bag, and the solar charging board and the charging line are placed in the charging board bag. The charging board bag has a window, the light-transmitting film covers the window, the optical fiber ribbon is arranged on the schoolbag, the solar charging board supplies power to the LED light-emitting diode, and the LED light-emitting diode is placed at any one of the two ends of the optical fiber ribbon. It is equippe...
