Detailed Description

Embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

In order to fully understand the technical scheme presented in the present application, the reason that the existing electric mask is heavier is firstly analyzed. The existing electric mask is mainly used for the following reasons: the first is to adopt the protective housing of full face formula, the second is to use built-in battery, the third is to use the filter core to admit air, especially the mode of filter core formula admit air, needs the power of increase fan, can further increase the weight of gauze mask.

Referring to fig. 1 and 2, an electric mask disclosed in an embodiment of the present application mainly includes a main body frame 11, a silica gel layer 12, a support 13, a fan 14, an expanded ptfe film 15, and ear strings 16, wherein the main body frame 11 is fixed on two sides of the main body frame, and the ear strings 16 are respectively fixed on two sides of the main body frame for being hung on ears of a user.

The main body frame 11 is provided with a silica gel layer 12 and an expanded polytetrafluoroethylene film 15, for the convenience of description, one side of the main body frame 11 close to the face of the user is an inner side, the other side is an outer side, the silica gel layer 12 is located on the inner side of the main body frame 11, and the expanded polytetrafluoroethylene film 15 is located on the outer side of the main body frame 11. The silicone layer 12 and the expanded polytetrafluoroethylene film 15 can form a closed space in cooperation with the main body frame 11, and the closed space is used for placing the bracket 13 and the fan 14.

The silica gel layer 12 has certain elasticity, can laminate in user's face, has seted up a breathing hole 121 on it, and the air through purifying can flow in the mouth of breathing person through breathing hole 121.

The support 13 is detachably connected to the main body frame 11, the fan 14 is installed on the support 13, and in the working process, the fan 14 rotates to push air at the expanded polytetrafluoroethylene film 15 to flow towards the direction close to the silica gel layer 12.

It should be understood that the gauze mask that demonstrates in this application is an active electronic gauze mask, and the supply capacity of air is far more than ordinary gauze mask, mainly uses under the condition such as haze weather or serious pollution area, and its main objective provides comparatively sufficient air volume for the user, avoids appearing the circumstances of suffocating.

It should also be appreciated that the motorized mask shown in the present application is not suitable for use in applications requiring strenuous exercise, such as running and the like.

It will also be appreciated that the fan 14 requires battery power when rotated and that the power supply portion of the fan 14 is removed for weight reduction and is instead portable, i.e. the power supply portion requires the user to be placed in a pocket, in the hand or in a backpack and connected to the fan 14 when in use.

Referring to fig. 5, the wires of the fan 14 are led out from the holes on the main frame 11, and a sealant may be injected into the holes for sealing. When the fan 14 is damaged and needs to be replaced, the sealant is removed, and the fan 14 is replaced by a new fan and sealed by the sealant again.

Referring to fig. 2, as an embodiment of the mask, a fixing frame 21 is hinged to the main frame 11, the fixing frame 21 can freely rotate around the hinge with the main frame 11, and the function of the fixing frame is to press the expanded ptfe film 15 on the main frame 11 for quick replacement.

The main body frame 11 and the fixing frame 21 may be fixed in various ways, and various ways such as screws and knobs may be used.

It should be understood that the active electric mask has a relatively high cost, and cannot be used once at present, so that the mode of replacing the expanded polytetrafluoroethylene film 15 is relatively economical and suitable, and the use cost can be effectively reduced.

It should also be understood that, in the use process, expanded polytetrafluoroethylene film 15 is located the outside, participates in the filtration at first, therefore needs to change at first, selects the mode of compressing tightly can realize quick replacement, and in some heavily polluted areas, the user can hand-carry several spare expanded polytetrafluoroethylene films 15, accomplishes in time to change.

Referring to fig. 2, 3 and 4, further, the main frame 11 is provided with a groove 22, and correspondingly, the fixing frame 21 is provided with a protrusion 23, and the groove 22 and the protrusion 23 are matched, so that when the fixing frame 21 is pressed on the main frame 11, the protrusion 23 can be clamped into the corresponding groove 22, and meanwhile, a part of the expanded polytetrafluoroethylene film 15 can be pressed into the groove 22, so that on one hand, a better fixing effect can be achieved, and on the other hand, the sealing effect can be correspondingly improved.

Further, the shape of the groove 22 and the protrusion 23 are both annular, which can form a tighter seal, further improving the fixing effect of the expanded ptfe film 15 and the sealing effect at the edge.

As a concrete implementation mode of the gauze mask that the application provided, silica gel layer 12 is pasted on main body frame 11, can use the mode of pasting that double faced adhesive tape or magic were pasted, and the mode of pasting is conveniently changed, can change when silica gel layer 12 can't reach operation requirement to the mode of pasting is changed conveniently, and it is also fast to change speed, and the experience of use is felt better.

In order to further improve the using effect, a photocatalyst layer 31 is added on the bracket 13, and the photocatalyst layer 31 is positioned between the expanded polytetrafluoroethylene film 15 and the fan 14. The photocatalyst layer 31 is mainly composed of two parts, namely filter cloth and photocatalyst paint coated on the filter cloth, and is used for further filtering effect.

Further, an ultraviolet generator is added between the expanded polytetrafluoroethylene film 15 and the photocatalyst layer 31 on the bracket 13, the ultraviolet generator is also fixed on the bracket 13, and the ultraviolet generator and the fan 14 share a power supply for sterilizing the inflowing air.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of the present application is not limited by the embodiments of the present application, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
