Description

Technical Field

[0001] The utility model relates to the field of air purification equipment, in particular to a multifunctional air purifier. Background Art

[0002] With the rapid development of air purification technology, there are many types of air purifiers on the market. They use different purification modes to achieve the purpose of air purification. These modes mainly include physical adsorption, water washing purification, etc. They each have their own unique purification principles and effects, but often have certain limitations.

[0003] Physical adsorption techniques, such as activated carbon adsorption, have strong adsorption capacity for gases and organic solvents, but have limited selective adsorption capacity for specific pollutants.

[0004] Water washing purification technology dissolves pollutants in the air into water through the contact of water mist with air. However, this technology is not effective in purifying some harmful substances that are difficult to dissolve in water and is prone to secondary pollution.

When faced with a complex environment where multiple air pollutants such as dust, formaldehyde, toluene and odor coexist, these air purifiers often find it difficult to achieve a comprehensive and efficient purification effect. Therefore, the development of an air purifier that can simultaneously and efficiently purify multiple air pollutants has become an urgent need for current technological development.

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0040] Although the air purifiers currently on the market use a variety of purification modes, each mode usually works independently and only has a good purification effect on a certain type of air pollutants. When faced with a complex environment where multiple air pollutants such as dust, secondhand smoke, formaldehyde, toluene and odor coexist, these air purifiers often find it difficult to achieve a comprehensive and efficient purification effect.

[0041] In order to solve the above technical problems, this embodiment provides a multifunctional air purifier. Figures 1 to 3 As shown, Figure 1 is a forward schematic diagram of the multifunctional air purifier in the embodiment, Figure 2 This is a back view schematic diagram of the multifunctional air purifier in the embodiment. Figure 3 Schematic diagram of an air purification device in an embodiment.

[0042] The multifunctional air purifier of this embodiment includes: a chassis 1, an air purification device 2, a humidifying device 3 and a heating device 4.

[0043] The chassis 1 is provided with a chamber 11, and an air outlet 12 and an air inlet 13 connected to the chamber 11, wherein the chamber 11 is used to accommodate the air purification device 2, the air inlet 13 is used to introduce the air to be purified into the chamber 11, and the air outlet 12 is used to output the purified air.

[0044] like Figure 3As shown, the air purification device 2 includes a filter 21, a graphene catalyst layer 22, a graphene activated carbon layer 23 and an exhaust fan 24 arranged inside the chamber 11. The exhaust fan 24 is used to guide the external air to be purified into the chamber 11 through the air inlet 13, and pass through the filter 21, the graphene catalyst layer 22, the graphene activated carbon layer 23 in sequence, and finally be discharged from the air outlet 12.

[0045] The humidifying device 3 is arranged inside the chassis 1 , and is used for generating water mist and transporting the water mist to the outside of the chassis 1 , so as to increase the humidity of the environment outside the chassis 1 .

[0046] The heating device 4 is disposed inside the chassis 1 and is used to increase the temperature inside the chamber 11 and the environment outside the chassis 1 .

[0047] When the multifunctional air purifier of the above technical solution is working, the external air enters the chamber 11 through the air inlet 13 under the guidance of the exhaust fan 24, and passes through the filter 21, the graphene catalyst layer 22 and the graphene activated carbon layer 23 in sequence. The filter 21 physically filters particulate matter such as dust, and the graphene catalyst layer 22 can decompose or convert air pollutants such as organic pollutants and nitrogen oxides into harmless substances through catalytic action. The graphene activated carbon layer 23 can adsorb odors and harmful gases in the indoor air, such as formaldehyde, toluene, etc.; at the same time, the humidifying device 3 can generate water mist, which can dissolve air pollutants dissolved in water and reduce the content of air pollutants before the external air enters the chamber, and the heating device 4 can increase the temperature of the external environment of the chamber 11 and the chassis 1, thereby promoting the volatilization of volatile organic pollutants and promoting the inactivation of viruses and bacteria. It can be seen that the multifunctional air purifier of the utility model can effectively purify a variety of air pollutants such as particulate matter, organic pollutants, odors, formaldehyde, toluene, etc. at the same time, and improve the air purification effect.

[0048] It is also important that the air purification device 2, humidification device 3 and heating device 4 of the multifunctional air purifier of the above technical solution can also work separately or in combination according to the needs of use, so as to adapt to different working scenes. For example, in an environment with good air quality, only the air purification device 2 can be operated alone, or in a usage scenario where only the air needs to be humidified or heated, the humidification device 3 or the heating device 4 can be operated alone, so as to reduce energy consumption and improve the applicability of the product.

[0049] In one embodiment of the humidifying device 3, see Figure 4 As shown, Figure 4It is a schematic diagram of the humidifying device in the embodiment, the humidifying device 3 includes a water tank 31, an atomizer 32 and a mist blowing fan 33. The water tank 31 is located below the filter 21 and can be fixed to the inside of the chassis 1 by bolts. The water tank 31 is provided with a mist outlet 301, a water inlet 302 for adding water and a sewage outlet 303 for draining water. The atomizer 32 is arranged in the water tank 31, and makes the water in the water tank 31 produce water mist when working. The mist blowing fan 33 is arranged on the water tank 31, and is used to blow the water mist in the water tank 31 to the outside of the chassis 1 through the mist outlet 301.

[0050] Exemplarily, the atomizer 32 is an ultrasonic atomizer 32 .

[0051] Exemplarily, the water tank 31 is also provided with a water level observation port 304 .

[0052] When the humidifying device 3 is working, pure water is first added to the water tank 31 through the water inlet 302, and the water level is observed through the water level observation port 304. After the water level reaches a suitable level, the atomizer 32 is started by controlling the humidifier control panel or remote control of the humidifying device 3. The atomizer 32 atomizes the water in the water tank 31, and then the mist fan 33 discharges the generated water mist evenly to the outside of the chassis 1 through the mist outlet 301.

[0053] Exemplarily, the humidifying device 3 also includes a fuse holder 34. The main function of the fuse holder 34 in the atomizer 32 is to provide circuit protection. It usually includes one or more fuses, which can quickly blow when an abnormal current (such as overload or short circuit) appears in the circuit, thereby disconnecting the circuit and preventing the equipment from being damaged or causing safety accidents such as fire.

[0054] Exemplarily, the humidifying device 3 also includes a humidity transmitter. When the ambient humidity is lower than the set value, the humidity transmitter will send a signal to the control system. After receiving the signal, the control system will start or increase the working intensity of the atomizer 32 to release more droplets to increase the ambient humidity. Conversely, when the ambient humidity reaches or exceeds the set value, the humidity transmitter will also send a signal to the control system, and the control system will reduce or stop the operation of the atomizer 32 to prevent the ambient humidity from being too high.

[0055] In another embodiment of the humidifying device 3 , the humidifying device 3 uses an existing humidifying device 3 .

[0056] In one embodiment of the above-mentioned heating device 4, refer to Figure 5 As shown, Figure 5 Schematic diagram of the heating device in the embodiment, the heating device 4 includes a casing 41, a heating element 42 and a heat sink 43, the casing 41 is fixed in the chassis 1 and is provided with a heat dissipation hole 401, the heating element 42 is arranged inside the casing 41, and the heat sink 43 is connected to the casing 41.

[0057] Exemplarily, the heating element 42 is an electric heating rod or an electric heating wire. A plurality of heating elements 42 are provided and arranged at equal intervals, so that the chamber 11 is heated more evenly.

[0058] When the heating device 4 is working, the heating element 42 is controlled to generate heat through the heating control panel 45 or the remote controller of the heating device 4 , and the heat is transferred to the outside through the heat dissipation holes 401 and the heat sink 43 , so that the temperature of the chamber 11 increases.

[0059] Exemplarily, the heating device 4 includes an overheating protection device 44, and the overheating protection device 44 is used to control the heating device 4 to stop working when the temperature in the chassis 1 is higher than a preset value.

[0060] To improve air filtration efficiency, refer to Figure 1 As shown, the humidifying device 3 and the heating device 4 are located below the filter 21; the air outlet 12 is located above the air inlet 13 and is located at the top of the chassis 1. In this arrangement, the air entering the air inlet 13 automatically rises after being heated, which improves the air flow efficiency and reduces the power requirement of the exhaust fan 24.

[0061] Further, see Figure 3 As shown, in order to facilitate the air to enter the chamber 11 and pass through the filter 21, the graphene catalyst layer 22, and the graphene activated carbon layer 23 more efficiently in sequence, the filter 21, the graphene catalyst layer 22, the graphene activated carbon layer 23 and the exhaust fan 24 are arranged in sequence from bottom to top in the chamber 11; wherein, the filter 21 can be detachably installed on the inner side of the chassis 1 by snaps, and the graphene catalyst layer 22 and the graphene activated carbon layer 23 are placed on the support frame on the inner side of the chassis 1. After the air enters the chamber 11, it can flow upward under the action of hot air and the exhaust fan 24 and pass through the filter 21, the graphene catalyst layer 22, and the graphene activated carbon layer 23 in sequence to achieve a purification effect.

[0062] Exemplarily, the exhaust fan 24 is fixed at a position inside the chamber 11 close to the air outlet 12 and is disposed toward the air outlet 12 .

[0063] To monitor air filtration effectiveness, refer to Figure 3 As shown, the air purification device 2 also includes an air quality sensor 25, an air control panel 26 and an indicator light 27. The air quality sensor 25 is used to detect the air quality above the graphene activated carbon layer 23 in the chamber 11, and the air control panel 26 is used to display the air quality and work according to the air quality control indicator light 27; wherein, the air quality sensor 25 may include an air index qualified sensor and an air index unqualified sensor, which are respectively used to detect qualified and unqualified air quality, and the indicator light 27 may include a qualified indicator light 27 and an unqualified indicator light 27, which are respectively used to indicate qualified and unqualified air quality when the air quality is qualified and unqualified.

[0064] In one embodiment of the filter screen 21, see Figure 3 As shown, the filter 21 includes a primary filter 211 and a HEPA filter 212 , and the primary filter 211 and the HEPA filter 212 are used to filter the air in the chamber 11 in sequence, such as being arranged in sequence from bottom to top in the chamber 11 .

[0065] For example, see Figure 6 As shown, Figure 6 The schematic diagram of the electric box in the embodiment, the air purification device 2 includes an electric box 28, in which a rectifier 201, a fan power supply 202, an AC contactor 203, an integrated circuit 204, a transformer 205, etc. are arranged. The electric box 28 is the control component of the air purifier, which provides suitable voltage and current for each electronic component during the operation of the air purifier to ensure the normal operation of the purifier. Among them, the rectifier 201 is mainly used to convert AC power into DC power, because some components in the air purification device, such as the integrated circuit 204 and the exhaust fan light 24, may require a stable DC power supply to operate; the fan power supply 202 provides power for each fan in the air purification device; the AC contactor 203 is an electromagnetic switch operated by electromagnetic suction, which is often used to control the start and stop of equipment such as motors, and the AC contactor 203 is used to control the power on and off of each fan, atomizer 32 and heating element 42, thereby realizing their switch control; the integrated circuit 204 is the core control unit in the air purification device, which is responsible for receiving and processing various sensor signals and controlling the operation of the air purification device according to a preset program or algorithm. For example, the integrated circuit 204 may automatically adjust the fan speed or switch to different filtering modes according to the data of the indoor air quality sensor. In addition, the integrated circuit 204 can also be connected to the air control panel 26 to control other functions of the air purification device, such as the display content of the air control panel 26, the flashing status of the indicator light 27, etc.; the transformer 205 is mainly used to adjust the power supply voltage to adapt to the voltage requirements of different components in the air purification device. For example, some sensors or integrated circuits 204 may require a lower voltage to work properly, while motors such as fans may require a higher voltage to generate sufficient airflow. The transformer 205 outputs an appropriate voltage by changing the amplitude of the input voltage to ensure that each component in the air purification device can operate stably at its rated voltage.

[0066] Exemplarily, a pulley or a universal wheel is provided at the bottom of the chassis 1.
