[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] The embodiment of the utility model discloses an air purification device.

[0034] See also Figure 1-Figure 6In an embodiment of the utility model, the air purification device includes a first air purification component 1, a second air purification component 2 and a first trigger switch; the first air purification component 1 is arranged on the top of the second air purification component 2 and can be rotated to form a first position set horizontally and a second position set obliquely; the first trigger switch is arranged between the first air purification component 1 and the second air purification component 2, and the first trigger switch is connected to the start and close control circuit of the air purification device; when the first air purification component 1 is rotated from the second position set obliquely to the first position set horizontally, the first trigger switch is triggered to disconnect the control circuit of the air purification device.

[0035] The inventor of the utility model found that when users turn off the existing air purification equipment, they usually adjust the flow adjustment device from the inclined second position to the lying first position first, and then press the power off button to turn it off. The operation steps are not simplified enough and cannot better improve the user experience. Based on this, in one embodiment of the utility model provided by the inventor, a first trigger switch is set between the first air purification component 1 and the second air purification component 2. When the user uses it, the first air purification component 1 is set from the horizontal first position (see Figure 1 ) to switch to the second position of the tilt setting (see Figure 2 ) to form an air flow discharged in the forward direction. At this moment, when the user needs to shut down the device, the first air purification component 1 can be rotated from the inclined second position to the horizontally set first position, which will trigger the first trigger switch to disconnect the control circuit of the air purification device, so that the air purification device can be shut down. There is no need to press the power off button, which simplifies the shutdown operation steps into one step, making the shutdown operation more convenient and improving the user experience.

[0036] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 In one embodiment of the utility model, the second air purification component 2 includes a second housing 21, a second fan 22 and a filter element 23 are arranged in the second housing 21, the filter element 23 is arranged at the lower side of the second fan 22, the top of the second housing 21 has a second air outlet 24, the circumferential outer side of the second housing 21 has a second air inlet 25, and the second fan 22 generates air flow from the second air inlet 25 to the filter element 23, and then to the second air outlet 24. In this arrangement, under the action of the second fan 22, the external air enters from the second air inlet 25, is filtered by the filter element 23, flows to the second air outlet 24, and then flows into the first air purification component 1, and finally is discharged from the first air purification component 1, the structure is simple, easy to manufacture and production, and the manufacturing difficulty is reduced.

[0037] See also Figure 1-Figure 4In one embodiment of the utility model, the first air purification component 1 includes a first housing 11, a first fan 12 is arranged in the first housing 11, a first air outlet 13 is provided at the top of the first housing 11, a first air inlet 14 is provided at the bottom of the first housing 11, and the first fan 12 generates air flow from the first air inlet 14 to the first air outlet 13. In this way, the purified air flowing out of the second air outlet 24 of the second air purification component 2 will flow into the first air inlet 14, and under the action of the first fan 12, it will be discharged from the first air outlet 13, the structure is simple, easy to manufacture and production, and the manufacturing difficulty is reduced.

[0038] See also Figure 4 and Figure 5 In one embodiment of the utility model, the first trigger switch includes a Hall switch 31 and a magnetic object 32 for cooperating with the Hall switch 31 to open and close. One of the Hall switch 31 and the magnetic object 32 is arranged in the first housing 11, and the other is arranged in the second housing 21. In this way, when the magnetic object 32 moves close to the Hall switch 31, the Hall element on the switch detection surface of the Hall switch 31 produces a Hall effect, which changes the internal circuit state of the Hall switch 31, thereby identifying the presence of a magnetic object nearby, and then controlling the on or off of the control circuit of the air purification device, thereby realizing the opening and closing of the air purification device. For example, when the first air purification component 1 is in the second tilted position, at this moment, the distance between the Hall switch 31 and the magnetic object 32 is far, and the Hall switch 31 makes the control circuit of the air purification device in a connected state, so the air purification device is in a working state to purify the air; when the first air purification component 1 is rotated from the second tilted position to the first horizontal position, the distance between the Hall switch 31 and the magnetic object 32 is short, and the Hall switch 31 recognizes the presence of a magnetic object nearby, and the Hall switch 31 makes the control circuit of the air purification device in a disconnected state, so the air purification device is in a closed state to be shut down.

In this way, when the first abutment member squeezes the transmission structure of the first micro switch, the internal contact of the first micro switch switches state, thereby controlling the on or off of the control circuit of the air purification device, thereby realizing the opening and closing of the air purification device. For example, when the first air purification component 1 is in the second position of the tilted setting, at this moment, the first abutment member does not squeeze the first micro switch, and the first micro switch makes the control circuit of the air purification device in a connected state, so the air purification device is in a working state to purify the air; when the first air purification component 1 rotates from the second position of the tilted setting to the first position of the horizontal setting, the first abutment member squeezes the first micro switch, so that the control circuit of the air purification device is in a disconnected state, so the air purification device is in a closed state to shut down.

[0040] In one embodiment, the first micro switch is a button type micro switch or a rocker type micro switch.
