[0002] Currently, with increasing air pollution and the widespread use of new building materials and interior decoration materials, indoor air quality is a serious concern, especially in winter when ventilation is insufficient or when air conditioning and heating are used in enclosed rooms. This leads to widespread exceedances of harmful gases such as formaldehyde, benzene, and ammonia, sometimes with indoor air pollution levels 5-10 times higher than outdoor levels. Air purifiers are a new type of household appliance that can solve indoor pollution problems. They can effectively remove formaldehyde, eliminate suspended dust, absorb smoke, sterilize and disinfect, and adsorb odors, demonstrating significant purification effects. Purifiers with negative ion generators can also replenish negative ions in the air, which is beneficial to human health and provides users with a comfortable air environment.

[0003] Currently, most air purifiers on the market have detachable, modular shells. During cleaning and maintenance, the front shell usually needs to be disassembled first. However, during the operation, operators often forget to unplug the main plug, which results in the air purifier being energized throughout the cleaning and maintenance process. This can easily lead to safety accidents and reduce the safety of the air purifier. Summary of the Invention

[0037] This invention proposes an air purification device.

[0038] Reference Figures 1 to 4 In one embodiment of the present invention, the air purification device includes a main housing 100 and a front housing 200. The front side 110 of the main housing 100 is provided with a micro switch 120 and a contact connection part 130. The micro switch 120 is used to control the on / off state of the air purification device circuit. The front housing 200 includes a control panel 300 and a switch pressing part 210. The control panel 300 includes an electrical connection mating part 310 corresponding to the contact connection part 130. The front housing 200 is detachably connected to the main housing 100. The switch pressing part 210 presses against the micro switch 120, and the electrical connection mating part 310 abuts against the contact connection part 130.

[0039] Specifically, the front shell 200 is detachably connected to the main shell 100 and covers the front side 110 of the main shell 100. The micro switch 120 is located on the front side 110, and the switch pressing part 210 for activating the micro switch 120 is located on the front shell 200. The switch pressing part 210 is set corresponding to the micro switch 120. When the front shell 200 is installed on the front side 110, the switch pressing part 210 will press against the micro switch 120, thereby realizing the circuit of the entire air purifier. When the front shell 200 is removed from the front side 110, the switch pressing part 210 will disengage from the micro switch 120, thereby cutting off the circuit of the entire air purifier. Such a power-off protection device can provide safer protection for the maintenance and cleaning of the air purifier.

[0040] Furthermore, currently available control panels 300 typically achieve electrical connection via connecting wires. If the housing containing the control panel 300 needs to be disassembled, an electrical connector is installed on the connecting wires. When installing the housing containing the control panel 300, the male and female terminals of the electrical connector must be connected before installing the housing 320. In contrast, this solution provides a contact connection part 130 for electrical connection of the control panel 300 on the front side 110. The electrical connection mating part 310 of the control panel 300 is located on the back of the front housing 200. When the front housing 200 is installed on the front side 110, the electrical connection mating part 310 automatically presses against the contact connection part 130 to achieve electrical connection. No other steps are required; simply installing the front housing 200 onto the main housing 100 is sufficient to achieve electrical connection of the control panel 300. This speeds up the electrical connection of the control panel 300, thereby increasing the installation efficiency of the housing. Therefore, this invention not only increases the safety of the air purification device but also accelerates the electrical connection of the control panel 300, thus increasing the installation efficiency of the housing.

[0041] Reference Figure 2 and Figure 4Optionally, in one embodiment, the mounting shell 320 of the control panel 300 protrudes from the back of the front shell 200, the electrical connection mating part 310 and the switch pressing part 210 are disposed on the back of the control panel 300, the front side 110 is provided with an electrical connection groove 140 corresponding to the back, the micro switch 120 and the contact connection part 130 are disposed at the bottom of the groove of the electrical connection groove 140, and the mounting shell 320 is at least partially disposed in the electrical connection groove 140; it can be understood that by disposing of the mounting shell 320 at least partially in the electrical connection groove 140, the groove wall of the electrical connection groove 140 interacts with the shell wall of the mounting shell 320, thereby restricting the position of the mounting shell 320. Since the micro switch 120 and the contact connection part 130 are located at the bottom of the electrical connection groove 140, and the electrical connection mating part 310 and the switch pressing part 210 are located on the back of the control panel 300, the relative stability between the mounting shell 320 and the electrical connection groove 140 increases the stability of the switch pressing part 210 against the micro switch 120 and the stability of the contact connection part 130 and the electrical connection mating part 310, thereby increasing the stability of the air purifier's power supply and the stability of the electrical connection of the control panel 300. Of course, the present invention is not limited to this. In other embodiments, a limiting structure can also be provided between the front shell 200 and the front side 110, for example, a limiting groove can be provided on the front side 110, and a limiting post can be provided on the front shell 200, with the limiting post located in the limiting groove.

[0042] Furthermore, the diameter of the electrical connection slot 140 gradually increases from the bottom to the opening, while the cross-sectional area of ​​the mounting shell 320 gradually decreases from near to far from the front shell 200. This means the larger opening of the electrical connection slot 140 and the smaller insertion end of the mounting shell 320 facilitates insertion. The gradually sloping walls of the electrical connection slot 140 and the sloping walls of the mounting shell 320 further guide insertion, improving installation efficiency. However, this invention is not limited to this. In other embodiments, the diameter of the electrical connection slot 140 from the bottom to the opening may remain unchanged, and the cross-sectional area of ​​the mounting shell 320 may remain unchanged from near to far from the front shell 200.

[0043] Furthermore, the wall of the electrical connection groove 140 at least partially protrudes from the front side 110; thus, to avoid water flowing out of the front side 110 along the wall of the electrical connection groove 140 during cleaning, or flowing downwards along the connection between the outer wall of the electrical connection groove 140 and the front side 110, thereby preventing water from flowing into the micro switch 120 and the contact connection portion 130, corroding the micro switch 120 and the contact connection portion 130, and causing safety accidents. Of course, the present invention is not limited to this; in other embodiments, the electrical connection groove 140 may also be recessed into the front side 110.

[0044] Furthermore, in one embodiment, the contact connection portion 130 is configured as a contact connection groove, and the electrical connection mating portion 310 is configured as a contact connection post, with the free end of the contact connection post abutting the bottom of the contact connection groove. This prevents cleaning or maintenance personnel from accidentally pressing on the micro switch 120 or accidentally touching the contact connection portion 130 when the front cover 200 is in the disassembled state, thus preventing electric shock. Of course, the present invention is not limited to this. In other embodiments, the contact connection portion 130 can also be configured as an electrical connection post, with a protective sleeve provided on the electrical connection post to prevent cleaning or maintenance personnel from directly contacting the electrical connection post and causing electric shock.

[0045] Optionally, in one embodiment, the front side 110 is provided with a switch arrangement groove, the micro switch 120 is disposed in the switch arrangement groove, and the switch pressing part 210 is configured as a switch top post. It can be understood that placing the micro switch 120 in the switch arrangement groove can prevent cleaning personnel or maintenance personnel from accidentally pressing the micro switch 120 and accidentally touching the contact connection part 130 when the front shell 200 is in the disassembled state, resulting in electric shock. Of course, the present invention is not limited to this. In other embodiments, the micro switch 120 may also be protruding from the front side 110, and a protective cover may be provided on the micro switch 120 to prevent cleaning personnel or maintenance personnel from accidentally pressing the micro switch 120.

[0046] In other embodiments, the contact connection portion 130 is configured as a contact connection groove, the electrical connection mating portion 310 is configured as a contact connection post, and the free end of the contact connection post abuts against the bottom of the contact connection groove; the front side 110 is provided with a switch arrangement groove, the micro switch 120 is disposed in the switch arrangement groove, and the switch pressing portion 210 is configured as a switch top post.

[0047] Optionally, a magnetic attraction assembly is provided between the front shell 200 and the main shell 100, and the front shell 200 is connected to the main shell 100 through the magnetic attraction assembly. This is because the magnetic connection has a simple structure, the magnetic connector is convenient and quick to connect, and no precise alignment is required; it only relies on the magnet to automatically attract, thereby saving time and speeding up the installation. Furthermore, the magnetic connection has strong connection stability, long service life, and flexible installation methods, including straight insertion, vertical insertion, side sliding, and any direction. Of course, the present invention is not limited to this; in other embodiments, the front shell 200 and the main shell 100 can also be connected by screws.

[0048] Further, in one embodiment, the magnetic attraction assembly may include a magnet disposed on the main housing 100 and a magnetic metal disposed on the front housing 200. In a second embodiment, the magnetic attraction assembly may include a first magnet disposed on the main housing 100 and a second magnet disposed on the front housing 200, wherein the opposite ends of the first magnet and the second magnet have opposite polarities.

[0049] Optionally, a plug-in assembly 400 is provided between the front shell 200 and the main shell 100. The front shell 200 is plugged into the main shell 100 through the plug-in assembly 400. The magnetic suction assembly and the plug-in assembly 400 are respectively located on opposite sides of the front shell 200. It can be understood that the plug-in connection method is simple and only requires one insertion action to achieve the connection.

[0050] Furthermore, this solution uses both magnetic and plug-in connection methods to connect the front shell 200 and the main shell 100, which can increase the stability of the connection between the front shell 200 and the main shell 100.

[0051] Furthermore, when installing the front shell 200 and the main shell 100, only one insertion action is required, and the magnetic attraction component will automatically engage, resulting in fast installation. Moreover, placing the magnetic attraction component and the plug-in component 400 on opposite sides of the front shell 200 further increases the stability of the connection. Of course, the invention is not limited to this; in other embodiments, the front shell 200 and the main shell 100 may also be connected solely by magnetic attraction.

[0052] Furthermore, the magnetic attraction component is located on the top side of the front shell 200, the plug-in component 400 is located on the bottom side of the front shell 200, and the bottom side of the main shell 100 is provided with a plug-in section extending outward from the main shell 100. The top surface of the plug-in section is provided with a plug-in portion 410, and the bottom side of the front shell 200 is provided with a plug-in mating portion 420 corresponding to the plug-in portion 410. It can be understood that by setting the plug-in portion 410 on the side section on the bottom side of the main shell 100 and on the top surface of the plug-in section, while the plug-in mating portion 420 is set on the bottom side of the front shell 200, the gravity of the front shell 200 itself can be used to make the plug-in more stable and increase the stability of the connection. Of course, the present invention is not limited to this. In other embodiments, the plug-in portion 410 can also be directly provided on the bottom side of the main shell 100, and the bottom side of the front shell 200 can be provided with a plug-in mating portion 420 corresponding to the plug-in portion 410.

[0053] Furthermore, in one embodiment, the insertion portion 410 is configured as an insertion groove, and the insertion mating portion 420 is configured as an insertion post, with the insertion post disposed within the insertion groove. Of course, the invention is not limited to this; in other embodiments, the insertion mating portion 420 is configured as an insertion groove, and the insertion portion 410 is configured as an insertion post, with the insertion post disposed within the insertion groove.

[0054] Optionally, in one embodiment, multiple sets of magnetic attraction components are provided, with these multiple sets of magnetic attraction components spaced apart on the top side of the front shell 200; it is understood that this can increase the stability of the connection between the front shell 200 and the main shell 100. In a second embodiment, multiple sets of plug-in components 400 are provided, with these multiple sets of plug-in components 400 spaced apart on the bottom side of the front shell 200. It is understood that this can increase the stability of the connection between the front shell 200 and the main shell 100.

[0055] In other embodiments, multiple sets of magnetic attraction components are provided, and the multiple sets of magnetic attraction components are spaced apart on the top side of the front shell 200; multiple sets of plug-in components 400 are provided, and the multiple sets of plug-in components 400 are spaced apart on the bottom side of the front shell 200.

[0056] Furthermore, the magnetic attraction components are provided in two sets, which are respectively disposed on opposite sides of the top side of the front shell 200; this allows the front shell 200 to be fixed on opposite sides of the top side of the front shell 200, increasing the stability of the front shell 200. Of course, the present invention is not limited to this. In other embodiments, the magnetic attraction components may also be provided in three sets, spaced apart on the top side of the front shell 200.

[0057] Furthermore, the plug-in assembly 400 is provided in two sets, with the two sets of plug-in assemblies 400 respectively disposed on opposite sides of the bottom side of the front shell 200. This allows the front shell 200 to be fixed on opposite sides of the bottom side of the front shell 200, increasing the stability of the front shell 200. Of course, the present invention is not limited to this; in other embodiments, the plug-in assembly 400 may also be provided in three sets, spaced apart on the bottom side of the front shell 200.

[0058] Furthermore, in this embodiment, there are two sets of magnetic suction components, which are respectively disposed on opposite sides of the top side of the front shell 200. There are also two sets of plug-in components 400, which are respectively disposed on opposite sides of the bottom side of the front shell 200. The magnetic suction components and plug-in components 400 are respectively disposed at the four corners of the front shell 200, which can increase the stability of the connection.

[0059] Reference Figure 3 Optionally, the air purifier also includes a positioning component 500, which includes a positioning rib 510 and a positioning frame 520. The positioning frame 520 is mounted on an external support, and the positioning rib 510 is located on the back of the main housing 100. The positioning rib 510 and the positioning frame 520 are detachably connected. Specifically, the external support can be a wall or a fixed plate. Since the motor of the air purifier will vibrate during use, the positioning component 500 is provided, and the positioning frame 520 of the positioning component 500 is mounted on the external support. The support frame is connected to the positioning rib 510 of the main housing 100. This allows the air purifier to be prevented from moving during use by utilizing the force of the external support.

[0060] Furthermore, the positioning component 500 also includes a pin 530. The positioning rib 510 has a first positioning hole, and the positioning frame 520 has a second positioning hole corresponding to the first positioning hole. The pin 530 passes through the first positioning hole and the second positioning hole to fix the positioning rib 510 and the positioning frame 520. It can be understood that the arrangement of the first positioning hole, the second positioning hole, and the pin 530 allows the pin 530 to be directly passed through the first positioning hole and the second positioning hole when connecting the positioning rib 510 and the positioning frame 520, thus achieving the connection between the positioning rib 510 and the positioning frame 520. This connection method is simple and fast, and can increase the positioning speed of the air purifier. Of course, the present invention is not limited to this. In other embodiments, the positioning rib 510 and the positioning frame 520 can also be hooked or snapped together.

[0061] Reference Figure 5 Optionally, the main housing 100 includes a side housing 150 and a back housing 160, which are detachably connected. It can be understood that dividing the main housing 100 into a side housing 150 and a back housing 160 facilitates maintenance and thorough cleaning, and speeds up maintenance efficiency and cleaning cleanliness.

[0062] Furthermore, the side shell 150 and the back shell 160 are connected by screws. This is because screw connections have low processing requirements, simple structure, are easy to assemble and disassemble, and screws are inexpensive; this can increase the installation efficiency of the side shell 150 and the back shell 160. Of course, the present invention is not limited to this. In other embodiments, the side shell 150 and the back shell 160 can also be connected by snap-fit.

[0063] Furthermore, the front shell 200 is tilted backward in the upward direction, and the angle between the front shell 200 and the vertical plane is in the range of 9° to 12°; that is, the front shell 200 is tilted towards the back shell 160 in the upward direction, and the angle between the front shell 200 and the vertical plane is in the range of 9° to 12°, which helps to increase the aesthetics of the air purification device.

[0064] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention.
