Description

Technical Field

[0001] The utility model relates to the technical field of air purification devices, and in particular to an intelligent air purifier based on bamboo-based materials. Background Art

[0002] In recent years, many air purifiers have appeared on the market. The main technical solution adopted is to design air inlets and outlets, and use fans to draw indoor air into the filter element for filtration and then discharge it through the air outlet. The product generally has a power switch, a small display screen to show the purification progress, or a three-color indicator light to fuzzily display the air quality.

[0003] In order to solve the above problems, there is a holographic display intelligent air purifier with a publication number of CN218583368U, which includes a shell, a display box and a holographic projector. The display box is arranged on the shell, and the display box has a receiving cavity. Part of the surface of the display box is located outside the shell; the holographic projector is arranged at the bottom of the display box, and the projection direction of the holographic projector is toward the display box, so that the projected image is displayed in the receiving cavity.

[0004] Although the utility model improves the display effect and intelligence of the air purifier by arranging the display box on the shell of the air purifier and projecting a three-dimensional image in the display box through the holographic projector, it cannot simultaneously decompose formaldehyde and absorb radon gas.

[0005] At present, the filter element materials on the market mainly use activated carbon for filtration and adsorption. Existing activated carbon mostly uses coconut shells, coal-made activated carbon, etc. The main disadvantages are that it cannot efficiently adsorb gas pollutants, the material cost is high, and the service life is short. The activated carbon in the filter element uses a single material, and the adsorbed pollutants cannot be decomposed in time, which is easy to cause secondary pollution of the activated carbon, reduce its service life, and have a certain impact on the environment.

The fan 2 is bolted to the inside of the lower housing 12, and the fan 2 is arranged horizontally. The horizontally arranged fan 2 facilitates the air to enter the multiple air inlets 111 on the housing 1.

[0031] The nano-modified bamboo charcoal filter element 4 is located below the fan 2 and is used to decompose formaldehyde and absorb radon. The nano-modified bamboo charcoal in the nano-modified bamboo charcoal filter element 4 is a bamboo charcoal product that has been processed by nanotechnology to improve its original performance or give it new functions. The nano-modified bamboo charcoal has a developed specific surface area and pore structure, and can more effectively absorb harmful substances in the air, such as formaldehyde, benzene, ammonia, sulfide, radon, etc. At the same time, by loading the nano-photocatalyst, that is, the internal titanium dioxide, the bamboo charcoal can excite photogenerated electron-hole pairs under light, and these electron-hole pairs can undergo redox reactions with organic pollutants adsorbed on the surface of the bamboo charcoal, decomposing them into harmless carbon dioxide and water, thereby improving the degradation efficiency of pollutants.

The radon sensor, the TVOC sensor and the formaldehyde sensor are all fixed to the upper part of the fan 2 by bolts. The touch screen 6 can display the gas data detected by the sensor assembly 5, so that the user can monitor the indoor gas concentration changes in real time.

[0035] Among them, TVOC sensor, whose full name is “Total Volatile Organic Compounds Sensor”, is a sensor device specifically used to detect the concentration of total volatile organic compounds (TVOCs) in the environment.

Figure 4 A base 13 is provided on the bottom of the lower housing 12, and the base 13 is in a cylindrical structure with one end open. The ultraviolet light strip 3 is arranged in a ring shape on the inner wall of the open end of the base 13. A protrusion 131 is provided on the middle of the bottom surface of the base 13, and the nano-modified bamboo charcoal filter element 4 is sleeved on the protrusion 131. The ring-shaped ultraviolet light strip 3 can irradiate the nano-modified bamboo charcoal filter element 4 in all directions, and decompose the adsorbed formaldehyde into water and carbon dioxide.

[0040] The protrusion 131 in this embodiment is cylindrical, and a groove for placing plant essential oil or fragrance 132 is provided on the top surface of the protrusion 131. The plant essential oil or fragrance 132 in the groove can bring fragrance to the room.

[0041] Specifically, refer to Figure 3 The controller assembly includes a control circuit board and a battery box 7. The battery box 7 is fixed inside the lower shell 12.

The voltage of the battery box 7 is 12V, and the battery box 7 supplies power to the main control board. The step-down circuit on the main control board converts the 12V DC voltage into 5V voltage and 3.3V voltage. The 5V voltage is used to power the fan 2 and the touch screen 6, and the 3.3V voltage is used to power the main control chip, the development board, the radon sensor, the formaldehyde sensor and the TVOC sensor on the main control board.

[0047] Active purification: At startup, the speed of Fan 2 can be set through the mobile phone and capacitive touch screen. When the formaldehyde sensor, TVOC sensor and radon sensor detect the corresponding gas concentration data, they will upload the corresponding gas concentration data to the mobile phone and capacitive touch screen through the development board for users to monitor the changes in indoor gas concentration in real time.
