[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] Example 1:

[0038] Example 1 of the present application discloses a multifunctional vehicle-mounted disinfection and sterilization purifier for efficiently disinfecting and purifying the air inside the vehicle.

[0039] Reference Figure 1 and Figure 2 A multifunctional vehicle-mounted disinfection and sterilization purifier includes a body 1 and a shell 11 that is detachably mounted on the body 1 by a buckle. An air inlet 10 is retained on the top of the body 1, and a plurality of ventilation holes 111 are provided through the shell 11. A detection component 2 is installed on the body 1 for detecting the air quality in the vehicle. A purification component 3 is installed on the body 1 for disinfecting and sterilizing the gas inside the vehicle. A control component 4 is installed on the body 1 for receiving the detection data of the detection component 2 and controlling the start and stop of the purification component 3 in real time according to the detection data, thereby realizing efficient purification of the gas inside the vehicle.

[0040] Reference Figure 1 and Figure 2 The detection component 2 includes a formaldehyde module 21 and a particulate matter module 22 mounted on the housing 1, and both the formaldehyde module 21 and the particulate matter module 22 are electrically connected to the control component 4. In this embodiment, the formaldehyde module 21 may be a formaldehyde sensor for detecting real-time formaldehyde concentration data in the air and transmitting the formaldehyde concentration data to the control component 4; the particulate matter module 22 may be a particulate matter sensor for detecting real-time particulate matter concentration data in the air and transmitting the particulate matter concentration data to the control component 4.

[0041] Reference Figure 1 and Figure 2 The purification component 3 includes an air induction member 31, a purification member 32, a fill light 33, and a negative ion module 34, all of which are controlled by the control component 4. The air induction member 31 is fixedly mounted on the top of the housing 1. In this embodiment, the air induction member 31 is an induced draft fan, which is used to guide external air into the interior of the housing 1 through the air inlet 10. The purification member 32 is installed inside the housing 1, with the height direction of the purification member 32 parallel to the height direction of the housing 11. The purification member 32 is located at the output end of the air induction member 31 to receive and purify the airflow introduced into the interior of the housing 1 by the air induction member 31.

[0042] Reference Figure 1 and Figure 2 The fill light 33 is fixedly mounted on the body 1 and is located at the bottom of the purification element 32 to provide illumination for the purification element 32. In this embodiment, the purification element 32 is made of a photocatalytic material. The fill light 33 can be a lamp bead to provide a light source of a specific wavelength (ultraviolet light or visible light) to the purification element 32 made of the photocatalytic material, thereby facilitating the purification element 32 to generate strong oxidizing free radicals, decomposing organic pollutants such as formaldehyde, bacteria, and viruses in the air.

[0043] Reference Figure 1 and Figure 2 The negative ion module 34 is fixedly mounted on the body 1. In this embodiment, the negative ion module 34 can be a negative ion generator for releasing negative ions to neutralize positively charged particles in the air (such as dust and allergens) and cause them to settle. In addition, some negative ions can destroy the structure of microorganisms, thereby sterilizing, disinfecting and purifying the air in the vehicle.

[0044] Reference Figure 1 and Figure 2 The control assembly 4 includes a display screen 41 and a control unit 42 mounted on the top of the housing 1. In this embodiment, the display screen 41 may be an LED screen, and the control unit 42 may be a single-chip microcomputer controller. The display screen 41 is electrically connected to the formaldehyde module 21 and the particulate matter module 22 to receive formaldehyde concentration data from the formaldehyde module 21 and particulate matter concentration data from the particulate matter module 22 via electrical signals, and to display the real-time formaldehyde concentration and particulate matter concentration.

[0045] Reference Figure 1 and Figure 2The formaldehyde module 21, particulate matter module 22, draft element 31, fill light 33, and negative ion module 34 are each controlled by a control element 42. The control element 42 receives formaldehyde concentration data from the formaldehyde module 21 and particulate matter concentration data from the particulate matter module 22 via electrical signals and compares the received data with pre-set values within the control element 42. When the formaldehyde concentration data and / or the particulate matter concentration data are higher than a predetermined value, the control element 42 activates the draft element 31, fill light 33, and negative ion module 34. Furthermore, when both the formaldehyde concentration data and the particulate matter concentration data are lower than a predetermined value, the control element 42 deactivates the draft element 31, fill light 33, and negative ion module 34.

[0046] Reference Figure 1 and Figure 2 The exterior of the vehicle body 1 is attached to a magnetic module via magnets. Inside the magnetic module are integrated aromatherapy, audio, and lighting. In this embodiment, the integrated aromatherapy diffuser is used to release fragrance to mask odors within the vehicle, enhancing interior comfort. The lighting can provide ambient lighting or localized illumination within the vehicle. The audio system plays white noise or a tone indicating the completion of sterilization by the purification component 3.

[0047] The implementation principle of a multifunctional vehicle-mounted disinfection and sterilization purifier in Example 1 of the present application is as follows:

[0048] The formaldehyde module 21 and particulate matter module 22 within the detection assembly 2 detect the formaldehyde concentration and particulate matter concentration in the air inside the vehicle body, and transmit the real-time detected formaldehyde concentration data and particulate matter concentration data to the control component 42 and the display screen 41. The display screen 41 displays the detected formaldehyde concentration data and particulate matter concentration data. When the real-time detected formaldehyde concentration data and / or particulate matter concentration data are higher than the predetermined value, the control component 42 activates the air induction component 31, the fill light 33, and the negative ion module 34.

[0049] The air inducing member 31 guides the air inside the vehicle body into the body 1 and flows toward the purification member 32. The fill light 33 provides light to the purification member 32, so that the purification member 32 purifies the formaldehyde and organic matter in the air. The negative ion module 34 releases negative ions to neutralize the positively charged particles in the air and causes them to settle, thereby achieving efficient disinfection, sterilization and purification of the air inside the vehicle body.

The positioning shaft 71 is rotatably mounted on the lifting frame 5 and is spaced apart along the circumference of the lifting frame 5. The cleaning brush 72 is fixedly mounted on the end of the positioning shaft 71 facing the lamp 112 to clean dust from the surface of the lamp 112. The driving member 73 is mounted on the lifting frame 5 to drive the cleaning brush 72 to rotate.

[0054] Reference Figure 4 and Figure 5 The drive member 73 includes a transmission gear 731 and a fixed rack 732. The transmission gear 731 is fixedly mounted on each set of positioning shafts 71, and the fixed rack 732 is mounted on the inner wall of the housing 11.

[0055] Reference Figure 4 and Figure 5Several groups of cleaning combs 113 for combing the cleaning brush 72 are fixedly installed on the inner wall of the shell 11. The cleaning combs 113 are distributed at intervals along the circumference of the shell 11, and the cleaning combs 113 are distributed at intervals along the height direction of the shell 11, so as to comb the dust attached to the surface of the moving cleaning brush 72.

[0056] Reference Figure 4 and Figure 5 Each set of positioning shafts 71 has an air guide wheel 711 fixedly mounted at the end away from the cleaning brush 72. A positioning rod 51 is fixedly mounted on the lifting frame 5. A dust cover 511 is mounted on the positioning rod 51 to cover the air guide wheel 711.
