[0041] like Figures 3 to 7 As shown, the aromatherapy device 37 includes a main body shell 20, an installation space is formed inside the main body shell 20, the main body shell 20 has a second side wall, on which a plurality of third air inlets 21 communicating with the installation space are provided, the main body shell 20 also has opposing third side walls and fourth side walls, the third side walls are provided with openings communicating with the installation space, and the fourth side walls are provided with passages 23 communicating with the installation space.

[0042] The aromatherapy device 37 includes an aromatherapy component 22, which includes a mounting bracket 24 with three first through openings. The mounting bracket 24 is installed at the opening on the third side wall, and optionally, it is installed by screws.

[0043] The aromatherapy component 22 also includes a strong magnetic sheet 26 and a light-emitting plate 25, which are sequentially inserted into the first passage.

[0044] The aromatherapy component 22 also includes three aromatherapy diffusers 2, one end of which passes through the light-emitting plate 25, the strong magnetic sheet 26 and the first access port and extends into the installation space.

[0045] The aromatherapy diffuser 2 has a magnetic plate inside, which is used to attract each other with the strong magnetic plate 26 to ensure the secure installation of the aromatherapy diffuser 2.

[0046] The aromatherapy device 37 also includes a switching component 1, which is disposed inside the installation space. The switching component 1 includes a switching housing, which includes a ventilation housing 7. The ventilation housing 7 has three receiving spaces for receiving the aromatherapy 2. One end of the aromatherapy 2 that extends into the installation space can extend into the receiving space.

[0047] The air exchange housing is equipped with an air inlet channel and an air outlet channel inside the corresponding accommodating space. The air inlet channel has a first passage 8 and the air outlet channel has a second passage 9. The first passage 8 and the second passage 9 are both located inside the air exchange housing 7 and are located on both sides of the accommodating space. The end of the first passage 8 and the second passage 9 near the aromatherapy component 22 is connected to the accommodating space.

[0048] The switching housing also includes a switching housing that is snapped into the ventilation housing 7. The switching housing includes a switching upper housing 10 and a switching lower housing 11 that are connected in a docking manner. The switching upper housing 10 is relatively close to the ventilation housing 7.

[0049] The air intake channel also has a third passage 12 and a second air intake 13. The third passage 12 and the second air intake 13 are respectively disposed inside the upper switching shell 10 and the lower switching shell 11, and the third passage 12 is connected to the first passage 8.

[0050] The air outlet channel also has a fourth passage 14 and a fifth passage 15, which are respectively located inside the upper switching shell 10 and the lower switching shell 11, and the fourth passage 14 is connected to the second passage.

[0051] The switching assembly 1 also includes a switching shaft 3 and a driving member 16 capable of driving the switching shaft 3 to rotate. The switching shaft 3 is rotatably disposed between the upper switching shell 10 and the lower switching shell 11. The driving member 16 is disposed outside the lower switching shell 11. The driving member 16 has a driving end that extends into the switching shell and is coaxially and fixedly connected to the switching shaft 3, and is capable of driving the switching shaft 3 to rotate.

[0052] The switching shaft 3 includes three connecting sections that are fixedly connected in sequence. The three connecting sections are respectively set for three accommodating spaces. Two through parts are provided on the circumferential direction of the connecting sections, which are recessed on the switching shaft 3. The through parts of the three connecting sections are all staggered. Thus, by rotating the switching shaft 3, the flow and closed states of the accommodating spaces can be switched respectively.

[0053] When the plane of the through section is parallel to the corresponding receiving space, the receiving space is in a flowing state; when the plane of the through section is perpendicular to the corresponding receiving space, the receiving space is in a closed state.

[0054] When the containment space is in a circulating state, the third passage 12 and the second air inlet 13 corresponding to the containment space are connected, and the fourth passage 14 and the fifth passage 15 are connected. Thus, external air can enter from the second air inlet 13 and enter the containment space through the third passage 12 and the first passage 8, carrying the fragrance of the aromatherapy 2 in the containment space through the second passage 9, the fourth passage 14 and the fifth passage 15 and finally exiting.

[0055] like Figure 8 As shown, the fan assembly 4 is installed inside the installation space. The fan assembly 4 includes an air outlet box 17, which has a first air inlet 5 and a first air outlet 6. The first air inlet 5 is connected to the fifth passage 15. It should be noted that the three fifth passages 15 are all connected to the first air inlet 5.

[0056] The fan assembly 4 also includes a second fan 18, which has a second input end and a second output end. The second input end is connected to the first air outlet 6, and the second output end is connected to an air outlet 19, which extends to the outside through the opening 23 of the main body shell 20.

[0057] Therefore, the second fan 18 is started, and the second input end generates suction. External air can enter the installation space from the third air inlet 21 of the main body shell 20, and then enter the air intake channel of the corresponding accommodating space in the circulation state. It carries the fragrance of the aromatherapy 2 located in the accommodating space from the air outlet channel into the air outlet box 17, and finally outputs it to the outside from the air outlet 19.

[0058] The aromatherapy component 22 also includes a snap-fit ​​panel 27, which is located on the side of the mounting bracket 24 away from the fan component 4. Correspondingly, the snap-fit ​​panel 27 is provided with a second passage for the aromatherapy 2 to pass through. A decorative panel 29 is provided on the side of the snap-fit ​​panel 27 away from the mounting bracket 24, which can optionally be connected by adhesive.

[0059] The control module is used to control the multi-functional aromatherapy purifier to switch between using multiple aromatherapy diffusers 2 and to indicate the use of the aromatherapy diffuser 2 by means of a light.

[0060] Specifically, such as Figures 5 to 7 As shown, the control module includes an indicator PCB board 31. A groove 30 is provided on the side wall of the ventilation housing 7 away from the first side wall. The indicator PCB board 31 is installed on the ventilation housing 7 through the groove 30. Three connection units 32 are provided on the indicator PCB board 31 corresponding to the three accommodating spaces. Correspondingly, a connection notch 33 adapted to the connection unit 32 is provided on the side wall of the light-emitting board 25. After the indicator PCB board 31 is inserted into the groove 30, the connection unit 32 can be located in the connection notch 33, thereby realizing the electrical connection between the indicator PCB board 31 and the light-emitting board 25.

[0061] Furthermore, the light panel 25 has three colors of light, namely green, yellow and red. Green light indicates that the aromatherapy diffuser 2 is being used, yellow light indicates that the remaining lifespan of the aromatherapy diffuser 2 is less than the set time, and red light indicates that the aromatherapy diffuser 2 needs to be replaced. Furthermore, the purifier housing 28 can be made of transparent material to facilitate the display of light colors.

[0062] Furthermore, the control module also includes an aromatherapy PCB board 41, which is disposed between the switching upper shell 10 and the ventilation shell 7. Optionally, the aromatherapy PCB board 41 and the switching upper shell 10 are connected by screws.

[0063] Furthermore, three pins 42 are provided on the side wall of the aromatherapy PCB board 41 away from the ventilation shell 7. The three pins 42 are respectively provided for the three aromatherapy 2. Correspondingly, the side wall of the ventilation shell 7 near the aromatherapy PCB board 41 is provided with a through hole 50 for the pins 42 to pass through and communicate with the receiving space.

[0064] Furthermore, the aroma diffuser 2 is also equipped with a chip unit, which records the fragrance type and remaining usage time of the aroma diffuser 2. The pin 42 extends through the through hole 50 into the aroma diffuser 2 and is connected to the chip unit to read the fragrance type and remaining usage time of the aroma diffuser 2. During the production of the aroma diffuser 2, the chip unit records the fragrance type and remaining usage time of the aroma diffuser 2. After the aroma diffuser 2 is installed, the pin 42 is connected to the chip unit. When the device is used, the three aroma diffusers 2 are selected by switching component 1. The containing space of the aroma diffuser 2 is switched to the flow state, and the remaining usage time recorded by the chip unit gradually decreases. When the containing space of the corresponding aroma diffuser 2 is switched to the closed state, the remaining usage time recorded by the chip unit stops changing.

[0065] Furthermore, the aromatherapy PCB board 41 is provided with a first set duration and a second set duration. When the aromatherapy PCB board 41 reads that the remaining usage time of the aromatherapy 2 is less than the first set duration but greater than the second set duration, the light-emitting board 25 lights up with a yellow light. When the aromatherapy PCB board 41 reads that the remaining usage time of the aromatherapy 2 is less than the second set duration, the light-emitting board 25 lights up with a red light.

[0066] like Figure 8 As shown, the control module also includes a control PCB board 34, which is located on the side of the second fan 18 near the second side wall. The indicator PCB board 31, the drive unit 16, and the second fan 18 are all electrically connected to the control PCB board 34, thereby starting the drive unit 16 and the second fan 18 to run. When a certain accommodating space is in a circulating state, the air outlet 19 can output the fragrance of the aromatherapy 2 located in the accommodating space. Correspondingly, the light panel 25 corresponding to the accommodating space lights up, indicating that the aromatherapy 2 is being used.

[0067] like Figure 9 and Figure 10 As shown, the mounting component 48 has an air inlet space on one side and an air outlet 39 on the top. The purifier device 38 includes a first fan 43, which has a first input end and a first output end. The first input end is connected to the air inlet space, and the first output end is connected to the air outlet 39.

[0068] Furthermore, the air outlet 19 is connected to the air inlet duct, and the air intake 35 is connected to the air inlet space;

[0069] Thus, the first fan 43 is activated, and the external air and the fragrance output by the aromatherapy device 37 can enter the air intake space, mix in the air intake space, and be output to the outside through the air outlet 36.

[0070] The purifier device 38 also includes a disinfection element 44, a detection element 45, and a negative ion generator 46. The disinfection element 44 is installed in the air intake space and is used to disinfect the air entering the air intake space. Optionally, the disinfection element 44 is an ultraviolet disinfection lamp.

[0071] The detection element 45 is mounted on the mounting element 48. The detection element 45 has a third input terminal. Correspondingly, the top of the mounting element 48 is provided with a detection port 51. The detection port 51 is connected to the third input terminal. The detection element 45 can detect the air quality of the surrounding environment. Specifically, it can detect the PM2.5 concentration in the air, so that users can choose whether to turn on the multi-functional aromatherapy purifier based on the PM2.5 concentration.

[0072] A negative ion generator 46 is mounted on a mounting bracket 48. The negative ion generator 46 has a contact 52 that extends into a first output terminal for ionizing air to generate negative ions to improve air quality.

[0073] The control module also includes a button unit 40, which is electrically connected to the control PCB board 34 and can control the device to switch between the three aroma diffusers 2 and control the air volume and speed output from the air outlet 36; the control module also includes a display screen, which can display information such as power, speed of the drive unit 16, the first fan 43 and the second fan 18.

[0074] It should be noted that the control module also includes a display screen, which can show which aromatherapy diffuser is being used, the duration of use, the color of the light, and the PM2.5 concentration value of the surrounding air.

[0075] It should be noted that an extension opening is provided on the top cover 47 at a position corresponding to the button unit 40. The button unit 40 extends out from the extension opening, making it convenient for the user to operate the button unit 40. By operating the button unit 40, the aromatherapy fragrance can be switched.

[0076] It should be noted that a filter section 53 is provided in the air intake space to filter the air entering through the air intake hole 35.

[0077] It should be noted that the control PCB board 34 is connected to an external controller, which can be a mobile APP or mini-program to achieve wireless control and facilitate use.

[0078] Working principle: When it is necessary to purify the surrounding environment, the device is activated by the button unit 40. The button unit 40 activates the drive unit 16, the first fan 43 and the second fan 18. The drive unit 16 drives the switching shaft 3 to rotate, so that the space containing the fragrance 2 to be used is in a circulating state. The second input end of the second fan 18 generates suction. External air enters the installation space from the third air inlet 21 and enters the space through the air intake channel corresponding to the space, carrying the fragrance of the fragrance 2 in the space. It enters the air outlet box 17 through the air outlet channel and finally outputs the fragrance to the air intake space from the air outlet 19. At the same time, the light panel 25 corresponding to the space lights up.

[0079] The first input end of the first fan 43 generates suction, and external air enters the air intake space through the air intake hole 35, mixes with the air carrying fragrance, and is simultaneously disinfected by the disinfection component 44. Then the mixed gas is output by the first fan 43 to the air outlet 36. During this process, negative ions are generated by the negative ion generator 46 to improve air quality.

[0080] When the user wants to switch to another fragrance 2, the button unit 40 activates the drive unit 16, which rotates the switching shaft 3 to switch the containing space from the open state to the closed state, and switches another containing space from the closed state to the open state. This allows the user to switch between different fragrances 2 and achieve different fragrance outputs. Correspondingly, the light panel 25 of the fragrance 2 being used lights up, indicating that the fragrance 2 is being used.

[0081] When the device needs to be turned off, it is controlled by the button unit 40. The drive unit 16 drives the switching shaft 3 to rotate, so that the planes of the three connecting sections on the switching shaft 3 are perpendicular to the corresponding accommodating spaces. Thus, all three accommodating spaces are in the closed state. At this point, the light panel 25 is turned off, and the drive unit 16, the first fan 43, the second fan 18, the disinfection unit 44, and the negative ion generator 46 stop operating.

[0082] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
