The charging interface and LCD screen are set on the casing, the power management module, lithium battery, single-chip microcomputer, GPS module, Wi-Fi module and purification unit are all set in the inner cavity of the casing, the filter is set at the air inlet, and the photocatalyst filter The net is set at the air outlet.

As a further limitation of the present utility model, the purification unit further includes a negative ion generator, which is arranged between the air inlet and the fiber filter, and the negative ion generator is connected to the power management module. The negative ion generator can effectively remove the bacteria and viruses adsorbed on the filter, improve the purification effect and prolong the life of the filter.

As a further limitation of the present utility model, the detection unit further includes a voice module connected to a single-chip microcomputer. The voice module can perform voice broadcasting of information such as local air quality under the control of the single-chip microcomputer, and the reminder effect is better.

As a further limitation of the present invention, the housing is hemispherical. The shell with a hemispherical structure can effectively accelerate the flow of air filtration and purification, and at the same time reduce the space occupied by the air purifier, which is small and portable.

As a further limitation of the present invention, the spherical surface of the housing is provided with three protrusions, and the protrusions are arranged to form an equilateral triangle for supporting the hemispherical housing.

Beneficial effects of the utility model: (1) The air purifier of the utility model realizes its own positioning through the detection unit, obtains the real-time air quality data of its own location, and displays it, which is convenient for users to check and use; (2) The purification unit uses a fiber filter to effectively filter 0.3 micron dust particles, and can decompose harmful organic substances in the air through the photocatalytic lamp and photocatalyst filter, and the air purification effect is good; (3) It can be powered by an external power supply through the charging interface, or can be used through Built-in lithium battery power supply, even without external power supply, can also achieve long-term battery life; (4) Small size, less space occupied, easy to carry.

detailed description

As shown in Figure 1-2, the utility model proposes a portable multifunctional air purifier based on the Internet of Things, including a hollow shell, a power supply unit, a detection unit and a purification unit, and the power supply unit supplies power to the detection unit and the purification unit. The housing 1 is provided with a switch button 2, a power indicator light 3, and relatively distributed air inlets 4 and air outlets; the detection unit includes a single-chip microcomputer, a GPS module, a Wi-Fi module and a liquid crystal display 5, and the single-chip microcomputer is respectively connected with the GPS module, The Wi-Fi module is connected to the LCD screen; the purification unit includes a fiber filter screen, fan, photocatalytic lamp and photocatalyst filter screen arranged in sequence; the power supply unit includes a charging interface connected in sequence, a power management module and a lithium battery, and the power management module is connected to Switch button, power indicator light, microcontroller, GPS module, Wi-Fi module, LCD display and fan. The charging interface 6 of the power supply unit and the liquid crystal display 5 of the detection unit are arranged on the casing 1, and the power management module, lithium battery, single-chip microcomputer, GPS module and Wi-Fi module are integrated on a circuit board and arranged in the inner cavity of the casing . The purification unit is also arranged in the inner cavity of the housing, distributed between the air inlet and the air outlet, the fiber filter is arranged at the air inlet, and the photocatalyst filter is arranged at the air outlet.

The switch button is used to start and stop the entire air purifier. After the device is turned on, the power indicator light shows green to indicate that it is running, the charging interface is connected to an external power supply or the lithium battery is fully charged, and the power indicator light is red to indicate that the charging interface is not connected to a power supply or the lithium battery is fully charged. insufficient. Built-in lithium battery, even without external power supply, it can work for a long time.
