Embodiment
The present invention is described in further detail below by embodiment combination accompanying drawing.
The embodiment of the present invention provides a kind of Novel anti-mist haze electric mask, and the mouth mask is used for the snout for being located at human body Position, the nose and mouth of human body are enveloped.As shown in drawings, it includes the first cover body 1 being detachably connected and the second cover body, the One cover body 1 and the second covers body are in the hood-like structure being outwards recessed, and second cover body is nested in the first cover body 1.Such as Fig. 9 It is shown, in addition to the glue cover 5 being connected with the second cover body, the elastically deformable of glue cover 5, so as to closely be pasted with human body face Close, the gas outlet 51 of unidirectional outlet is provided with the bottom of glue cover 5, the gas of characteristics of contaminated respiratory droplets will flow out from the gas outlet 51.This goes out Gas port 51 can use the structure design of existing mouth mask, specifically, the pellosil of unidirectional outlet can be set in gas outlet 51.First cover The edge of body 1, which is additionally provided with clip 10, clip 10, to be used to bind respirator belt, then respirator belt can be enclosed on human body head, Cover body is set to be held in the face of human body.
As shown in figure 1, the bottom of the lateral surface of first cover body 1 is provided with some through holes 11, through hole 11 is through described the One cover body 1, through hole 11 as mouth mask air inlet.Because mouth mask is the nose and mouth that are located at human body, then by cover body close to people The position of body mouth is set as bottom, the top that cover body is set close to the position of human body nose, below-mentioned corresponding cover The top or bottom of body are with reference to the setting.
The bottom of the lateral surface of second cover body is provided with fan mouthful 21, and the fan mouthful 21 is provided with blower tray 22, described The inner side of blower tray 22 is provided with fan(Do not illustrate fan in figure).Blower tray 22 is specifically made up of multiple connecting rods, multiple Connecting rod has common connection end, and the connecting rod other end is connected with the inwall of fan mouthful 21, and the centre of its common connection end is provided with socket, Fan is plugged in socket and can rotated relative to socket.When the fan is rotated, outside air is adsorbed onto from the through hole 11 In fan mouthful 21.Cavity is provided with second cover body, the top of the medial surface of the second cover body is provided with two and human body nostril phase Corresponding air-vent 31, the air-vent 31 is connected with fan mouthful 21 by cavity, then air will sequentially pass through through hole 11, wind Mouth 21, cavity and air-vent 31 are fanned, human body nasal cavity is entered back into.The outside of the blower tray 22 is provided with standing groove 23, described Multi-disc screen pack independent of each other is stacked with standing groove 23(Do not illustrate screen pack in figure), screen pack can be in standing groove 23 Naturally stack, the medial surface and standing groove 23 of first cover body 1 will grip the screen pack.When need change screen pack When, the first cover body 1 and the second cover body can be dismantled, the screen pack that being extracted out from screen pack to change is changed, and Without carrying out integral replacing to all screen packs, this undoubtedly facilitates the replacing of filtering, also reduces the maintenance cost of screen pack.
Wherein, multiple screen packs can be configured according to filtration needs.In one embodiment, the screen pack includes Washable polymeric membrane net, compared to existing HEPA nets, polymeric membrane net removes PM2.5 effect more preferably, and can enter Water-filling is washed, so as to after washing, can be continuing with, is just extended its service life, is also reduced the maintenance cost of screen pack.
Further, the screen pack also includes sterilization net and active carbon net, and sterilization net is used to sterilize, and active carbon net can To adsorb some dust, polymeric membrane net, sterilization net and active carbon net are sequentially arranged along the flow direction of air.It is many by setting Individual screen pack, can thoroughly filter to the air of suction fan mouthful 21, the air of suction human body is more cleaned, totally.
In one embodiment, the lateral surface of second cover body is provided with outstanding arc convex 24, described first The medial surface of cover body 1 is provided with the groove 14 matched with the arc convex 24, and the arc convex 24 can be connected to described recessed In groove 14, so as to realize being detachably connected for the first cover body 1 and the second cover body.The mode of this clamping is more prone to card than buckle Enter and separate so that more convenient operation.Certainly, for dismounting of being more convenient for, arc convex 24 may be configured as with appropriate elasticity Deformation behavior.
In one embodiment, as seen in figures 3-6, second cover body includes the fan guard 2 being detachably connected and connection Cover 3, fan guard 2 is the hood-like structure caved inward, and connect cover 3 is nested in fan guard.Accordingly, fan mouthful 21, fan branch Frame 22, standing groove 23 and arc convex 24 are arranged on fan guard 2, and the air-vent 31 is opened in the top of connect cover 3.Wind Fan cover 2 and connect cover 3 can be realized by buckle or screw to be detachably connected, consequently facilitating to the dimension of the second cover body internal fan Shield.
Specifically, the inner side of the fan guard 2 is provided with the coaming plate 26 around the fan, the coaming plate 26 is surrounded in arc-shaped In the outside of fan, and the coaming plate 26 is provided with the opening 27 of the air-vent 31, then gas will enter from fan mouthful 21, Again air-vent 31 is blowed to through opening 27.Also lid is covered with clamping plate 4 on coaming plate 26, and clamping plate 4 is provided with shaft hole, and fan is arranged on rotating shaft In hole, and clamping plate 4 and blower tray 22 will grip the fan.The space that coaming plate 26 and clamping plate 4 are enclosed just is reduced Flow into discharge capacity of the air to other spaces so that gas is conveyed to air-vent 31 as far as possible, and which increases the gas to human body Body conveying capacity.Simultaneously as the presence of clamping plate 4, gas is blown and beaten on clamping plate 4, then by the transition of opening 27, from air-vent 31 enter human body nasal cavity, and the discomfort of human body face is directly blown and beaten this reduces gas, improve the comfortableness that mouth mask is used.
Further, as shown in Figure 5, Figure 6, the connect cover 3 is provided with outstanding baffle plate towards the one side of fan guard 2 32, the baffle plate 32 is located at opening 27, and it blocks a part for opening 27 to reduce opening 32, just further buffering The mobilization force of gas, further reduces the discomfort that gas directly blows and beats human body face, improves the comfortableness that mouth mask is used.
In one embodiment, as shown in fig. 7, the outer surface of the clamping plate 4 is provided with neck 41, the neck 41 is used to put It is set to fan and battery and corresponding drive circuit of power etc. is provided.As shown in figure 1, the outer surface of first cover body 1 is set There are the control button 12 for controlling fan work and the charging inlet 13 being connected with the battery, be manipulated by button 12 can control fan work whether, battery can then be charged by charging inlet 13.Further, the coaming plate 26 outside, which is provided with, is used to placing the cabling channel 28 of wire, the connecting wire and charging inlet 13 of control button 12 and fan with The connecting wire of battery is arranged in cabling channel 28.
In one embodiment, as shown in figures 4 and 9, the edge of the fan guard 2 is provided with multiple outstanding nose bars 25, the glue cover 5 is provided with the hole clipping 55 matched with the nose bar 25, and the nose bar 25 is pluggable in the hole clipping 55, So as to realize being detachably connected for fan guard 2 and glue cover 5.
Above content is to combine specific embodiment further description made for the present invention, it is impossible to assert this hair Bright specific implementation is confined to these explanations.For general technical staff of the technical field of the invention, do not taking off On the premise of from present inventive concept, some simple deduction or replace can also be made.
