[0042] The detailed description and technical contents of this application will be described as follows with the accompanying drawings. However, the attached drawings are for illustrative purposes only and are not intended to limit this application.
[0043] See also Figure 1 One embodiment of the present application provides a wearable air purification device, which includes a host 100, a mask 200, a strap 300 and an eyepiece 400.
[0044] See also Figures 2 to 4 and Figures 7 and 8 In this embodiment, the host 100 has an air inlet 111 and an air outlet 112, and an inlet flow channel 113 is defined in the host 100. Specifically, the surface of the host 100 is opened to form the air inlet 111 and the air outlet 112, and the inlet flow channel 113 is defined by the shape of the internal structure of the host 100 itself. In the simplest implementation, a single air inlet 111 and a single air outlet 112 can achieve the intended effect of supplying air in and out of the inlet flow channel 113 of the present application, but the present application does not limit the number of the air inlet 111 and the air outlet 112. The inlet flow channel 113 is connected between the air inlet 111 and the air outlet 112, and the air inlet 111 and the air outlet 112 are arranged on the same side of the host 100. Specifically, the host 100 includes a body 152 and an outer cover 151 disposed on one side of the body 152 . The outer cover 151 is disposed on the opposite side of the air inlet 111 and the air outlet 112 . The outer cover 151 is assembled with the body 152 to define an inlet air passage 113 between the outer cover 151 and the body 152 .
[0045] In this embodiment, an air inlet filter 114 and a fan 130 are provided inside the host 100, and the air inlet filter 114 and the fan 130 are provided on the inlet air passage 113. The fan 130 is used to drive air from the external environment to flow into the inlet air passage 113 through the air inlet 111 and flow to the air outlet 112.
[0046] In this embodiment, the host 100 has an exhaust inlet 121 and an exhaust outlet 122, and an exhaust flow channel 123 is defined inside the host 100. The exhaust flow channel 123 is connected between the exhaust inlet 121 and the exhaust outlet 122, and the exhaust flow channel 123 is separated from the intake flow channel 113. The exhaust inlet 121, the intake port 111, and the outlet 112 are arranged on the same side of the host 100, and the exhaust outlet 122 is arranged on the other side of the host 100. Specifically, the exhaust inlet 121 is arranged on the lower side of the outlet 112. In addition, the exhaust flow channel 123 is provided with an exhaust valve 124.
[0047] The host 100 is provided with a first magnetic member 101 for magnetic attraction. Specifically, the first magnetic member 101 is disposed on the upper side of the air outlet 112. In this embodiment, the first magnetic member 101 is accommodated in the host 100. In the simplest implementation, a single first magnetic member 101 can achieve the magnetic attraction effect expected by the present application. In this embodiment, two identical first magnetic members 101 are provided on the host 100 to increase the magnetic attraction force, but the present application does not limit the number of the first magnetic members 101.
[0048] See also Figure 1 and Figures 4 to 6 The mask 200 is disposed on the host 100, and the air outlet 112 and the exhaust inlet 121 are both connected to the mask 200. The mask 200 is used to cover the user's mouth and nose. In this embodiment, the mask 200 is a mask body made of soft rubber, for example, the mask 200 can be made of silicone.
[0049] The strap 300 is set on the host 100. When the user wears the wearable air purification device of the present application, the strap 300 is used to restrain the user's head to fix the host 100 in front of the user's face, and the mask 200 fits the user's face closely.
[0050] See also Figure 5 to Figure 6 , the eyepiece 400 is provided with a second magnetic component 402, and the second magnetic component 402 is arranged on one side of the eyepiece 400 and buried in the eyepiece 400. The second magnetic component 402 and the first magnetic component 101 are magnetically attracted to each other so that the eyepiece 400 is arranged on the eyepiece 400, and the eyepiece 400 is arranged on one side of the air outlet 112. Specifically, the eyepiece 400 is arranged on the upper side of the air outlet 112 to shield the user's eyes. In this embodiment, one of the first magnetic component 101 and the second magnetic component 402 is magnetic, such as a magnet, and the other of the first magnetic component 101 and the second magnetic component 402 is non-magnetic and can be magnetically attracted, such as iron; or, both the first magnetic component 101 and the second magnetic component 402 are magnetic, such as two magnets with opposite polarities. Therefore, the first magnetic component 101 and the second magnetic component 402 can be magnetically attracted to each other. Therefore, the eyepiece 400 is easy to assemble to or detach from the host 100. Moreover, the first magnetic component 101 and the second magnetic component 402 are respectively embedded in the host 100 and the eyepiece 400 and are not exposed (for example, by encapsulation injection molding or embedded assembly and then covered with a cover body), so that the first magnetic component 101 or the second magnetic component 402 can be prevented from falling off due to pulling when the eyepiece 400 is detached.
[0051] See also Figures 7 and 8In this embodiment, the host 100 may selectively further include at least an electric sterilization module 140. The electric sterilization module 140 and the fan 130 are disposed on the inlet air duct 113. In this embodiment, a pair of electric sterilization modules 140 are disposed, and the present application does not limit the number of the electric sterilization modules 140. Each electric sterilization module 140 includes a pair of two electrode sheets 141, 142 spaced apart and disposed on both sides of the inlet air duct 113.
[0052] See also Figures 2 to 4 When the electric sterilization module 140 is working, high voltage electricity is loaded between its two electrode sheets 141 and 142. Therefore, when the inhaled airflow passes between the two electrode sheets 141 and 142, the bacteria carried by it can be destroyed by the high voltage electricity. The air is sterilized by high voltage electricity, and then filtered through the air intake filter element and supplied to the mask 200 through the air outlet 112 for the user to inhale. The exhaust inlet 121 is arranged on the lower side of the air outlet 112 to match the airflow direction of the user's inhalation and exhalation. The user's exhaled gas enters the exhaust flow channel 123 through the exhaust inlet 121 and is discharged into the ambient air through the exhaust outlet 122 through the exhaust valve 124. The separation of the intake flow channel 113 and the exhaust flow channel 123 can prevent the user's exhaled gas from being discharged through the exhaust flow channel 123 and then flowing back to the intake flow channel 113 to pollute the intake air.
[0053] See also Figure 4 , 7 And 8, the flow direction of the exhaust valve 124 is toward the outside of the body, so it can block the unpurified ambient air from entering the mask 200 through the exhaust channel 123. In this embodiment, the exhaust valve 124 is detachably assembled in the host 100, and the exhaust valve 124 can be removed from the host 100 for easy cleaning. Specifically, the exhaust valve 124 can be a diaphragm that can be movably attached to the outside of the exhaust inlet 121 (the outside refers to the downstream of the predetermined flow direction of the exhaust channel 123). When the user inhales to reduce the pressure in the mask 200, the exhaust valve 124 is close to the exhaust inlet 121 and closes the exhaust inlet 121. When the user exhales to increase the pressure in the mask 200, the exhaust valve 124 is pushed outward and separated from the exhaust inlet 121, so the exhaust inlet 121 is opened.
[0054] See also Fig. 9 As shown in the schematic diagram of another embodiment of the present application, different host machines 100 can also be selected according to different usage environments. In this embodiment, corresponding to the usage environment with severe dust but relatively free of germs, only an air intake filter 114 can be configured in the corresponding inlet flow duct 113 within the host machine 100, and a larger air intake filter 114 can be configured to block the air inlet port 111.
[0055] The wearable air purifier of the present application has a mask 200 for covering the user's mouth and nose, and the wearable air purifier also has an eyepiece 400, which is disposed on the host 100 and is used to cover the user's eyes. Moreover, the eyepiece 400 is magnetically assembled to the host 100, so it can be selectively installed on the host 100 or removed from the host 100 according to different usage environments.
[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the patent scope of the present application. Other equivalent changes that apply the patent spirit of the present application should all fall within the patent scope of the present application.
