[0018] The following describes in detail the embodiments of the present invention, but the present invention is not limited to these, and various modifications are possible within the scope of the description, and embodiments obtained by appropriately combining the technical means disclosed in the different embodiments are also included in the technical scope of the present invention.

[0019] First, the wearable air purifying device according to the present invention will be specifically described with reference to Figs.

[0020] The wearable air purifying device according to the present invention comprises a host 100, a mask 200, and a band 310.

[0021] As shown in FIG. 2 to FIG. 6, in this embodiment, the host 100 has an air inlet 111 and an outlet 112, and an air flow path 113 is defined in the host 100. To be more specific, an opening is opened on the surface of the host 100 to form the air inlet 111 and the outlet 112, and the air flow path 113 is defined by the surrounding shape of the internal structure of the host 100 itself. In the simplest implementation, the expected effect of the present disclosure is achieved by one air inlet 111 and one outlet 112 to advance air to the air flow path 113, but the present disclosure is not limited to the number of air inlets 111 and outlets 112. In this embodiment, the host 100 is provided with two air inlets 111 arranged to face each other on both the left and right sides of the outlet 112 and the outlet 112, respectively, to increase the amount of air supplied. The ventilation flow path 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 main body 152 and an outer cover 151 covering one side of the main body 152, the outer cover 151 being arranged on the opposing side of the air inlet 111 and the air outlet 112, and the outer cover 151 being assembled to the main body 152 defines the ventilation flow path 113 between the outer cover 151 and the main body 152.

[0022] As shown in Fig. 2 to Fig. 6, in this embodiment, the ventilation filter 114 and the fan 130 are installed inside the host 100, the ventilation filter 114 and the fan 130 are installed in the ventilation flow path 113, and the ventilation filter 114 separates the fan 130 from the air inlet 111. In this embodiment, the fan 130 is installed in the air outlet 112, but the present invention is not limited thereto. In this embodiment, a jig 160 is installed in the main body 152, and the ventilation filter 114 is clamped by the jig 160 and fixed to the main body 152, and is arranged to cross the air flow path 113. The fan 130 is used to make air flow from the external environment through the air inlet 111 into the ventilation flow path 113 and flow toward the air outlet 112.

[0023] 2 to 6, in this embodiment, the host 100 has an exhaust inlet 121c and an exhaust outlet 122, and an exhaust flow path 123 is defined in the host 100. The exhaust flow path 123 is connected between the exhaust inlet 121c and the exhaust outlet 122, and the exhaust flow path 123 is separated from the ventilation flow path 113. The exhaust inlet 121c, the air supply port 111, and the blow-out port 112 are disposed on the same side of the host 100, and the exhaust outlet 122 is disposed on the other side of the host 100. Specifically, the exhaust inlet 121c is disposed below the blow-out port 112. In addition, an exhaust valve 121b is provided in the exhaust flow path 123.

[0024] 1 to 6, the mask 200 is installed in the host 100, and the air outlet 112 and the exhaust inlet 121c are both connected to the mask 200. The mask 200 is used to cover the nose and mouth of a user. In this embodiment, the mask 200 is a mask body made of soft vinyl, and for example, the mask 200 may be made of silicone.

[0025] The band 310 is attached to the host 100. When a user wears the wearable air purifying device according to the present disclosure, the band 310 is fastened to the user's head, the host 100 is fixed in front of the user's face, and the mask 200 is brought into close contact with the user's face (see FIG. 1).

[0026] Specifically, the band 310 includes a head holder 311 connected to the upper side of the host 100 and a neckband 312 connected to the lower side of the host 100. The head holder 311 is used to hold the host 100 around the user's head, and the neckband 312 is used to hold the host 100 around the user's neck.

[0027] As shown in Figures 2 to 10, air is filtered by an air vent filter, passes through the air outlet 112, and flows into the mask 200, where it is inhaled by the user. The exhaust inlet 121c is disposed below the air outlet 112, and corresponds to the airflow direction of the user's inhalation and exhalation. The gas exhaled by the user enters the exhaust flow path 123 from the exhaust inlet 121c, passes through the exhaust valve 121b and the exhaust outlet 122, and is discharged into the ambient air. The ventilation flow path 113 and the exhaust flow path 123 are separate, and the gas exhaled by the user is circulated back to the ventilation flow path 113 after being discharged from the exhaust flow path 123, so as not to contaminate the supply air.

[0028] Since the flow direction of the exhaust valve 121b is directed to the outside of the aircraft body, it is possible to sufficiently prevent the situation in which unpurified environmental air passes through the exhaust flow path 123 and enters the mask 200. Specifically, in this embodiment, the exhaust module 121 is installed in the exhaust flow path 123, and the exhaust module 121 is removably assembled inside the exhaust outlet 122 (the inside refers to the upstream side in the predetermined flow direction of the exhaust flow path 123). The exhaust module 121 includes a grill 121a and the above-mentioned exhaust valve 121b. The exhaust inlet 121c is formed in the grill 121a. The exhaust valve 121b is installed in the grill 121a, and the exhaust valve 121b may be movably attached to a film sheet located outside the exhaust inlet 121c (the outside refers to the downstream side in the predetermined flow direction of the exhaust flow path 123). When the internal pressure of the mask 200 decreases due to the user's inhalation, the exhaust valve 121b is tightened to the grill 121a, and the exhaust inlet 121c is closed. When the internal pressure of the mask 200 increases due to the user's exhalation, the exhaust valve 121b is pushed outward and separated from the exhaust inlet 121c, thereby opening the exhaust inlet 121c. The exhaust module 121 can be removed from the host 100 for cleaning.

[0029] As shown in FIGS. 7 to 10, in this embodiment, the host 100 is equipped with an electric sterilization module 140, and the electric sterilization module 140 and the fan 130 are installed in the ventilation channel 113.

[0030] In this embodiment, the electric sterilization module includes an electrode element 141a installed on the main body. The electric sterilization module further includes another electrode element 142a installed on the outer cover, and the two electrode elements 141a and 142a are arranged on opposite sides of the air flow passage. Specifically, one of the two electrode elements is a positive electrode plate, and the other of the two electrode elements is a negative electrode plate. When the electric sterilization module 140 is operated, a high voltage is applied between the two electrode elements 141a and 142a, so that when the inhaled airflow passes between the two electrode elements 141a and 142a, the pathogens contained therein are destroyed by the high voltage.

[0031] As shown in Figures 2 to 5, air is sterilized by high voltage and filtered by an air vent filter before passing through the air outlet 112 and flowing into the mask 200, where the user inhales. The exhaust inlet 121c is disposed below the air outlet 112 and corresponds to the airflow direction of the user's inhalation and exhalation. The gas exhaled by the user enters the exhaust inlet 121c into the exhaust flow path 123, passes through the exhaust valve 121b and the exhaust outlet 122, and is discharged into the ambient air. The ventilation flow path 113 and the exhaust flow path 123 are separate, so that the gas exhaled by the user is not discharged from the exhaust flow path 123 and then circulated back into the ventilation flow path 113 to prevent contamination of the supply air.

[0032] As shown in FIG. 3 to FIG. 5, the flow direction of the exhaust valve 121b is directed to the outside of the machine body, so that it is possible to sufficiently prevent the situation where unpurified environmental air passes through the exhaust flow path 123 and enters the mask 200. In this embodiment, the exhaust valve 121b is removably assembled in the host 100, and the exhaust valve 121b can be removed from the host 100 for cleaning. Specifically, the exhaust valve 121b may be movably attached to a film sheet located outside the exhaust inlet 121c (the outside refers to the downstream side of the exhaust flow path 123 in a predetermined flow direction). When the pressure inside the mask 200 decreases due to the user's inhalation, the exhaust valve 121b is tightly connected to the exhaust inlet 121c, so that the exhaust inlet 121c is closed. When the pressure inside the mask 200 increases due to the user's exhalation, the exhaust valve 121b is pushed outward and separated from the exhaust inlet 121c, so that the exhaust inlet 121c is opened.

[0033] As shown in FIG. 1 to FIG. 6, the host 100 is further selectively provided with an eyepiece 400, which is disposed on one side of the air outlet and used to shield the user's eyes. In this embodiment, the host 100 is provided with a first magnetically attracted member 101 for magnetic attraction, specifically, the first magnetically attracted member 101 is disposed on the upper side of the air outlet 112. In this embodiment, the first magnetically attracted member 101 is accommodated in the host 100. In the simplest implementation, the magnetic attraction effect expected in this disclosure is achieved by one first magnetically attracted member 101. In this embodiment, the host 100 is provided with two identical first magnetically attracted members 101 to enhance the magnetic attraction force, but the number of the first magnetically attracted members 101 is not limited in this disclosure. The eyepiece 400 is assembled to be magnetically attracted to the host 100, and can therefore be selectively attached to or detached from the host 100 according to different usage environments.

[0034] The configuration of the second embodiment of the present invention is shown in Figures 11 to 14. In this embodiment, the electrode elements 141b of the electric sterilization module 140 are all installed on the main body 152, and the electrode elements 141b are negative brushes, which is different from the first embodiment. In the present disclosure, the number of electrode elements 141b on the main body 152 is not limited.

[0035] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means devised in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
