Description

Technical Field

[0001] The present invention relates to a face mask device capable of improving the filtering performance of dust and the like, and particularly capable of effectively filtering pollutants in a severely polluted environment. Background Art

[0002] In recent years, there have been more and more pollutants in the air, and the types of pollutants have become more and more diverse. Therefore, the usage rate of masks has been increasing.

[0003] Generally, a mask is quadrilateral and cannot fit the user's face. It needs to be worn by hanging on the ears with ropes such as rubber bands, and the user also needs to adjust the ropes, so it is very troublesome. Not only is it inconvenient to wear, but the filtering effect of pollutants is also quite poor.

[0004] In particular, for workers who only wear filter masks to work in an environment where a large amount of dust is generated, due to being in a polluted environment for a long time, the filter is contaminated by foreign matters such as dust and cannot fully exert its filtering function, and the worn mask is easily rendered useless.

[0005] In a severely polluted situation, although an oxygen mask equipped with an oxygen tank that can supply oxygen by itself can be worn, this oxygen mask is heavy and inconvenient to wear, which will seriously hinder the work of workers.

[0006] To improve these problems, the present inventor proposed a face mask device in Patent Registration Bulletin No. 10-2067401. This face mask device uses water as a filtering medium to filter pollutants, and the present invention has developed and applied for a face mask device capable of further extending the duration of the filtering performance of the face mask device by performing self-purification treatment on the water used as the filtering medium.

In addition, it should not be construed as limited to the embodiments described in this specification, but should be understood to include all modifications, equivalents, or alternatives within the spirit and scope of the present invention.

[0040] The present invention will be described in detail below with reference to the accompanying drawings.

[0041] Figure 1 is an overall structure diagram of a mask device according to an embodiment of the present invention.

[0042] Referring to Figure 1 , the mask device 100 of this embodiment includes: a main body frame 110, the main body frame 110 is configured to wrap the user's neck and shoulders, and store water, and use the water as a filtering medium to filter the air; a mask 120, the mask 120 can cover the user's respiratory organs; an intake hose 130, the intake hose 130 is used to connect the main body frame 110 and the mask 120 to supply filtered air to the mask 120; an exhaust hose 140, the exhaust hose 140 is used to connect the main body frame 110 and the mask 120 to transport the air discharged from the mask 120 to the main body frame 120. Preferably, the main body frame 110 further includes a disinfection module 200, and the disinfection module 200 disinfects the water used as a filtering medium.

[0043] The interior of the main body frame 110 is divided into an air chamber 111 and a water storage part 112. The air chamber 111 has airtightness and is used to store filtered air. The water storage part 112 is used to store water. The air chamber 111 and the water storage part 112 can be separated by a selective permeable membrane 115. The selective permeable membrane 115 can be provided by a permeable membrane that allows selective permeation of liquids and gases. Only the air from the water storage part 112 can permeate through the selective permeable membrane 115 to the air chamber 111 side. Such a selective permeable membrane 115 can be provided in the form of a sealed bag for storing water inside the main body frame 110.

[0044] The main body frame 110 is provided with an external air introduction pipe 113 for supplying external air to the water storage part 112. The external air introduction pipe 113 is provided with a ventilation port 114 for introducing external air. The front end of the external air introduction pipe 113 for discharging external air is immersed in the water storage part 112.

[0045] In this embodiment, the introduction pipe 113 bifurcates from the ventilation port 114 to both sides, and the front ends are respectively immersed in specific intervals L of the water storage part 112. A plurality of exhaust holes 113a are formed on the specific intervals L, so that the external air introduced through the introduction pipe 113 is divided into fine bubbles through the plurality of exhaust holes 113a and then contacts the water in the water storage part 112. In this process, pollutants such as dust in the external air are collected in the water, and the filtered air passes through the selective permeable membrane 115 and enters the air chamber 111.

[0046] The front end of the intake hose 130 located inside the main body frame 110 is arranged in the air chamber 111, so that the filtered air in the air chamber 111 enters the mask 120. The front end of the outlet hose 140 located inside the main body frame 110 is arranged inside the water storage part 112, so that the air discharged from the mask 120 enters the water storage part 112 and contacts the water, thereby being filtered. A gasket member 116 for preventing water leakage can be provided at the connection part of the intake hose 130 and the outlet hose 140 with the main body frame 110.

[0047] The intake hose 130 connects the main body frame 110 and the mask 120, so that the air filtered by the water storage part 112 enters the mask 120. Preferably, the mask device 100 includes a first one-way valve 131, and the first one-way valve 131 can adjust the flow direction of the air to a single direction to prevent backflow. A specific interval of the intake hose 130 can be formed into a corrugation or the whole is composed of a corrugated pipe, so as to be able to bend freely.

[0048] The outlet hose 140 connects the main body frame 110 and the mask 120, so that the air discharged from the mask 120 enters the water storage part 112. Preferably, the mask device 100 includes a second one-way valve 141, and the second one-way valve 141 can adjust the flow direction of the air to a single direction to prevent backflow. Like the intake hose 130, a specific interval or the whole of the outlet hose 140 is composed of a corrugated pipe, so as to be able to bend freely.

[0049] According to the mask device of the present invention, when the user wears the mask 120 and inhales, the first one-way valve 131 opens and the second one-way valve 141 closes, and the filtered air in the air chamber 111 only enters the air chamber 111 through the intake hose 130 to be supplied to the mask 120. At the same time, when the user exhales, the first one-way valve 131 closes and the second one-way valve 141 opens, and the discharged air only enters the air chamber 111 through the outlet hose 140. The discharged air contacts the water in the water storage part 112, and after being filtered, it enters the air chamber 111 again.

[0050] Thus, with the breathing of the user, the first one-way valve 131 and the second one-way valve 141 are selectively opened, filtered air is inhaled through the intake hose 130, and the discharged air is discharged through the outlet hose 140.

[0051] On the other hand, when the mask device is used for a long time, the water used as the filtering medium becomes turbid due to being contaminated by dust or pollutants, resulting in a reduction in air filtration performance. Therefore, the present invention is characterized in that self-purification treatment can be performed while wearing the mask device.

[0052] Preferably, the main body frame 110 further includes a disinfection module 200 for disinfecting the water stored in the water storage part 112 by adding a disinfectant. More preferably, the disinfection module 200 includes: a medicine box 210 for loading the disinfectant in the form of tablets; and a mixing part 220 for dissolving the disinfectant added through the medicine box 210 into the water stored in the water storage part 112 for mixing. Hereinafter, with reference to the related drawings, the disinfection module, which is the main part of the present invention, will be specifically described.

[0053] Figure 2 is an excerpt Figure 1 of the main part of the Figure 3 is an excerpt Figure 1 of the main part of the Figure 4 is an excerpt Figure 1 of the main part of the Figure 5 is an excerpt Figure 1 of the main part of the Figure 5 Only the main body frame and the disinfection module are shown, excluding the mask.

[0054] Referring to Figures 2 to 5 , the main body frame 110 may include a first main body frame 110a and a pair of second main body frames 110b. Among them, the first main body frame 110a is in a U shape to wrap around the back of the user's head, and a pair of second main body frames 110b are arranged at both ends of the first main body frame 110a and are located at the chest of the user. Preferably, the lower ends of the pair of second main body frames 110b are connected by a third main body frame 110c. The first main body frame 110a, the second main body frame 110b, and the third main body frame 110c may be hollow square tubes that communicate with each other, so that the internal space provides the aforementioned air chamber and water storage part, and there is an introduction pipe inside. Preferably, the water storage part includes the third main body frame 110c. In addition, a ventilation port is provided on the first main body frame 110a, and external air enters through this ventilation port. The second main body frame 110b or the third main body frame 110c may include a plug for facilitating the discharge of the water stored in the water storage part or the replenishment of water.

[0055] Preferably, a pair of second main frames 110b and a first main frame 110a are assembled by a hinge pin 117, and there is an airtight member (not shown) at the hinge part. The pair of second main frames 110b can rotate within a specific angle θ range relative to the first main frame 110a within the range of maintaining airtightness.

[0056] A handle 118 that can be held can be provided on each second main frame 110b. The handle 118 can be slidably provided along the length direction of the second main frame 110b to adjust the fixed position between the handle 118 and the second main frame 110b.

[0057] The disinfection module 200 communicates with a third main frame 110c including a water storage part, and can add a disinfectant to the water stored in the water storage part to disinfect the water as a filtering medium. The disinfection module 200 includes: a medicine box 210 for loading a disinfectant in the form of tablets; a mixing part 220 for mixing the disinfectant added through the medicine box 210 into the water stored in the water storage part 112 for dissolution. This embodiment shows 2 disinfection modules 200 arranged symmetrically left and right. The two disinfection modules 200 are the same. Therefore, in the following description, the two disinfection modules 200 are not distinguished, and only one disinfection module 200 is used for description.

[0058] Figure 6a and Figure 6b is a cross-sectional view of the medicine box in the mask device according to an embodiment of the present invention. Referring to Figure 6a , the medicine box 210 of this embodiment includes: a medicine box main body 211, the medicine box main body is rotatably assembled to the mixing part 220, and is formed with a medicine loading hole 214 parallel to the direction of the rotation axis C for loading the disinfectant 10; an elastomer 212, the elastomer 212 is arranged in the medicine loading hole 214 to elastically support the disinfectant 10. A support plate 213 can be further arranged between the disinfectant 10 and the elastomer 212. The medicine box main body 211 can be formed with a hinge assembly hole 211a recessed on the rotation axis C and an assembly groove 211b recessed along the outer peripheral surface. The medicine box 210 is rotatably assembled to the mixing part 220 through the hinge assembly hole 211a and the assembly groove 211b.

[0059] In the present invention, the disinfectant is provided in the form of tablets, and a chlorine-containing disinfectant that can dissolve in water to kill pathogens can be used. As the chlorine-containing disinfectant, calcium hypochlorite or dichloroisocyanuric acid can be used. Calcium hypochlorite is a white solid chlorinating agent, which is high-purity neutral calcium hypochlorite, characterized by good storage stability, very few insoluble substances after dissolving in water, and the effective chlorine content of high-quality neutral calcium hypochlorite is above 70%. Dichloroisocyanuric acid is made by chlorinating a chemically stable compound isocyanuric acid and is a white solid chlorinating agent. In addition, in addition to the chlorine-containing disinfectant, a flocculant that can aggregate pollutants can be used alone or together with the chlorine-containing disinfectant.

[0060] In addition, as Figure 6b shown, the medicine box 310 can be loaded with two or more disinfectants 10 by lengthening the length of the medicine loading hole, and the user can disinfect twice or more in the state of wearing the mask device.

[0061] Figure 7 is a perspective view of the mixing part in a disassembled state in the mask device according to an embodiment of the present invention.

[0062] Referring to Figure 7 , the mixing part 220 includes: a first housing 222, on which a rotatable first rotating blade 221 is provided; a motor 223 for driving the rotation of the first rotating blade 221; a second housing 225, on which a freely rotatable second rotating blade 224 is provided, and the second housing 225 is connected to the medicine box 210, and the disinfectant 10 loaded in the medicine box 210 will be added into the second housing 225; cover brackets (such as a first cover bracket 226 and a second cover bracket 227), the first rotating blade 221 and the second rotating blade 224 are rotatably pivotally connected to the cover brackets (such as the first cover bracket 226 and the second cover bracket 227) so that the first housing 222 and the second housing 225 communicate with each other; and a fixing bracket 228 for communicating the first housing 222 and the water storage part 112 with each other.

[0063] The first rotating blade 221 is inserted into the interior of the first housing 222, and a through hole 222a is formed on a part of the outer peripheral surface of the first housing 222. The fixing bracket 228 is assembled around the through hole 222a of the first housing 222, and the fixing bracket 228 is assembled with the third main body frame 110C so that the first housing 222 communicates with the water storage part.

[0064] The motor 223 is provided on one side of the first housing 222 for driving the rotation of the first rotating blade 221.

[0065] The second housing 225 is provided with a freely rotatable second rotating blade 224, and one side surface thereof is connected to the medicine box 210 to add the disinfectant loaded in the medicine box 210. In this embodiment, the second housing 225 has a hollow shape with both ends open, one open end is assembled with the cover brackets (such as the first cover bracket 226 and the second cover bracket 227), and the other open end is assembled with the medicine box 210 through a stop plate 229.

[0066] A dosing hole 229a corresponding to the charging hole 214 of the medicine cartridge 210 is formed on the stop plate 229. The stop plate 229 is fixed to the second housing 225, and the open end of the second housing 225 is inserted into the assembly groove 211b of the medicine cartridge 210. The medicine cartridge 210 can rotate relative to the second housing 225. The rotation shaft of the second rotating blade 224 is inserted into the hinge assembly hole 211a of the medicine cartridge 210 and can rotate freely.

[0067] Preferably, the mask device 100 includes a switch 340. When the charging hole 214 of the medicine cartridge 210 and the dosing hole 229a of the stop plate 229 are aligned, the switch 340 can recognize it so that the disinfectant in the medicine cartridge 210 can be added to the second housing 225. As a specific embodiment of such a switch 340, at the rotation angle φ at which the charging hole 214 of the medicine cartridge 210 and the dosing hole 229a of the stop plate 229 are aligned, a first contact 341 and a second contact 342 are respectively provided on the assembly surface of the stop plate 229 and the medicine cartridge 210. When the first contact 341 and the second contact 342 come into contact, an electrical signal is generated. This electrical signal is transmitted to the control unit described later and is recognized as a signal that the disinfectant has been added into the second housing 225.

[0068] The first rotating blade 221 and the second rotating blade 224 are rotatably pivoted on the cover brackets 226, 227 so that the first housing 222 and the second housing 225 communicate with each other. Preferably, the cover brackets (such as the first cover bracket 226 and the second cover bracket 227) include the first cover bracket 226 having a first hinge hole 226a and the second cover bracket 227 having a second hinge hole 227a. The rotation shaft C1 of the first rotating blade 221 is pivoted to the first hinge hole 226a, and the rotation shaft C2 of the second rotating blade 224 is pivoted to the second hinge hole 227a. The rotation shaft C1 of the first rotating blade 221 and the rotation shaft C2 of the second rotating blade 224 are arranged side by side on different axes. The first cover bracket 226 and the second cover bracket 227 are respectively formed through the peripheries of the first hinge hole 226a and the second hinge hole 227a to communicate the first housing 222 and the second housing 225 with each other.

[0069] Therefore, when the disinfectant in the medicine cartridge 210 is added to the second housing 225, the motor 223 is driven to rotate the first rotating blade 221, and an axial flow is generated in the first housing 222. Based on the axial flow generated in the first housing 222, the rotation shaft C1 of the first rotating blade 221 and the eccentric second rotating blade 224 rotate freely along with the second rotation shaft C2 (C1≠C2), prompting the disinfectant added into the second housing 225 to dissolve and mix quickly. In this way, the disinfectant added into the second housing 225 quickly diffuses into the water storage part of the main body frame through the first housing 222 to disinfect the water stored in the water storage part.

[0070] Figure 8 It is a block diagram of a control system of a face mask device according to an embodiment of the present invention.

[0071] Referring to Figure 8 , the face mask device of this embodiment includes: a control unit 310 for performing electrical control; a water quality sensor 320 for detecting the water quality of the water stored in the water storage part; a switch 340 for identifying whether the disinfectant stored in the medicine box is added to the second housing. Preferably, the face mask device may further include a warning device, and the warning device reminds the user whether the water stored in the water storage part is polluted according to the detection signal of the water quality sensor 320. In this embodiment, the warning device is exemplified as a warning light 330. When the warning light on the face mask device is lit, the user can identify that the water stored in the water storage part is polluted. On the other hand, such a warning device is not limited to a warning light and may also be a speaker that emits an alarm sound.

[0072] The water quality sensor 320 is used to detect the quality of the water stored in the water storage part. For example, it may be an oxygen saturation sensor for detecting the oxygen saturation in the water.

[0073] The control unit 310 receives the detection signal from the water quality sensor 320. When it is determined that the degree of pollution of the water stored in the water storage part is lower than a specific level, it warns the user through the warning device. After the user recognizes the warning signal, a rotation operation is performed on the medicine box 210, so that the disinfectant contained in the medicine box 210 is added to the second housing 225. Then, when the disinfectant is added to the second housing 225, the control unit 310 receives the electrical signal of the switch 340 and drives the motor 223 to rotate, so that the disinfectant is quickly dissolved and mixed to disinfect the water stored in the water storage part.

[0074] Figure 9a and Figure 9b are respectively a perspective view of the face mask of the face mask device according to an embodiment of the present invention and a perspective view in a disassembled state.

[0075] Referring to Figure 9a and Figure 9b , the face mask 120 of this embodiment includes: a face mask main body 122 formed with an opening and having wing parts 121 extending to both sides; an extended main body part 123 assembled on the opening part of the face mask main body 122 to form a space; a face mask cover part 124 assembled on one side opening part of the extended main body part 123 for sealing one side opening part of the extended main body part 123.
