Abstract
The utility model discloses a mask with a demisting function. The mask comprises a mask screen, a drive element, a lower swing rod, an upper swing rod, a scraping piece support and a scraping piece, wherein the lower end of the lower swing rod is connected with the drive element so as to swing under driving of the drive element, the lower end of the upper swing rod is connected with the upper end of the lower swing rod through a joint pin shaft, the scraping piece support is fixedly arranged on the upper swing rod, and the scraping piece is arranged on the scraping piece support and tightly attached to the mask screen. On the condition that a breathing mask is fully sealed, the mask with the demisting function can conveniently clean mist generated on the mask screen in the mask in real time. Therefore, the fact that rescue or production work are smoothly carried out is guaranteed, and unnecessary safety hidden risks are avoided in the rescue or production process.
Description
Technical field
The utility model relates to a kind of breathing equipment, relates in particular to a kind of face shield.
Background technology
Along with the extensive use in the respiratory protection industry of new technology, new science and technology, the full facepiece mask with respiratory protection function derives increasing miscellaneous function, thereby makes breathing mask when satisfying basic need, has also increased comfortableness and the practicality worn.
In actual use, for the sealing of the face shield that ensures respiration, be in all the time an airtight environment in face shield, at this moment due to the existence of internal-external temperature difference, user's Exhaled gasesS inevitably can form fog on the inner surface of face shield face screen.Especially in the arctic weather situation, knot mist phenomenon can be more obvious.If fog can not in time be removed, can cause considerable influence to user's the visual field, thereby bring obstacle for rescue or production work; But in the indefinite situation of extraneous environmental gas, rashly take face shield and wipe fog, bring hidden danger also can for user's safety, because the life security that extraneous pernicious gas may jeopardize the user.When many enterprises wish to obtain a kind of the use without the breathing mask of fog.
The utility model content
The purpose of this utility model is to provide a kind of face shield with defrosting function, in the situation that the user does not take face shield, facilitate the fog on removal face screen, thereby make the user obtain the better visual field in rescue or the course of work, in order to implement smoothly rescue work.
In order to achieve the above object, the utility model provides a kind of face shield with defrosting function, and it has a cover screen, and it also comprises a driving element;
One draft link, its lower end is connected with driving element, with the driving lower swing at driving element;
One upper pendulum bar, its lower end is connected with the upper end of described draft link by a joint bearing pin;
One wiper blade holder is fixed on described upper pendulum bar;
One scraping blade is fixed on described wiper blade holder, and described scraping blade and face shield face screen fit tightly.
Face shield with defrosting function described in the utility model mainly drives draft link by driving element, and then drives upper pendulum bar and swing, and upper pendulum bar is connected by the joint bearing pin with draft link.Be connected with wiper blade holder due to upper pendulum bar and draft link is connected with driving element, when the draft link driven element orders about motion, draft link interlock upper pendulum bar, upper pendulum bar can drive the scraping blade that fits tightly face shield and swing back and forth along its curved surface, thereby realize the purpose of face screen removing fog.
Further, in the face shield with defrosting function described in the utility model, described wiper blade holder is one to have flexible sheet metal.In order to make scraping blade fit tightly the face screen, the technical program adopts the elastomeric material that can carry out deformation according to the curved surface of face screen.
Further, at the face shield with defrosting function described in the utility model, described driving element is a motor.
Further, the face shield with defrosting function described in the utility model also comprises the holddown spring of being located between described draft link and upper pendulum bar, to provide a thrust to the scraping blade that is fixed on wiper blade holder, itself and face shield face screen is fitted tightly.In order to improve the degree that fits tightly of scraping blade and face screen, make scraping blade hold with the face screen protection all the time in motion process to contact by applying a thrust.
Owing to having adopted technique scheme, to compare with the prior art scheme, the face shield with defrosting function described in the utility model has following good effect:
(1) in the hermetic situation of breathing mask, in time remove easily the fog that produces on face shield inner face screen, thereby guarantee carrying out smoothly of rescue or production work, avoid occurring unnecessary potential safety hazard in rescue or production process.
(2) in the preferred version of the technical program, by spring compression design, scraping blade and face screen are fitted tightly, thereby improve except fog effect;
(3) in the preferred version of the technical program, wiper blade holder can be shielded curved surface according to face and be carried out deformation, thereby has improved the fog effect that removes of this device;
Description of drawings
Fig. 1 is the front view of face shield under a kind of embodiment with defrosting function of the present utility model.
Fig. 2 is the cutaway view at Figure 1A-A place.
The specific embodiment
Below will be further explained the face shield with defrosting function described in the utility model according to specific embodiment of the utility model and Figure of description, but this explanation does not consist of improper restriction of the present utility model.
Fig. 1 has shown the structure of face shield under a kind of embodiment with defrosting function described in the utility model, and Fig. 2 has shown the structure of the face shield with defrosting function in Fig. 1 at the A-A place.
As depicted in figs. 1 and 2, the face shield with defrosting function described in the utility model comprises face shield face screen 1, scraping blade 2, upper pendulum bar 3, joint bearing pin 4, holddown spring 5, wiper blade holder 6, draft link 7 and drive motors 8; Wherein the lower end of draft link 7 is connected with drive motors 8, and it can swing under the driving of drive motors 8; The lower end of upper pendulum bar 3 is connected with the upper end of draft link 7 by joint bearing pin 4, can drive upper pendulum bar and swing when draft link swings; Wiper blade holder 6 is fixedly arranged on upper pendulum bar 3, and it can swing along with the swing of upper pendulum bar; Scraping blade 2 is fixed on wiper blade holder 6, scraping blade 2 fits tightly with face shield face screen, in the present embodiment, for being changed according to the curved surface of face shield face screen 1, wiper blade holder 6 regulates, wiper blade holder 6 has adopted has certain flexible sheet metal, and scraping blade 2 just can swing along with the swing of upper pendulum bar along the curved surface of face shield face screen 1 like this; Simultaneously, be provided with holddown spring 5 between draft link 7 and upper pendulum bar 3, in order to thrust to be provided to scraping blade 2, itself and face shield face screen 1 fitted tightly more.
In the present embodiment, scraping blade can not form cut at the face screen surfaces when preventing demist, and scraping blade can adopt the silica gel material, or other similar materials.When selection material, thereby scraping blade should satisfy and has certain hardness and can strike off fog on face screen, can not stay cut on the face screen again simultaneously.
In actual mechanical process, the user opens the switch 9 that is arranged on mask body 10, to start drive motors 8, drive motors 8 drives draft link 7, draft link 7 drives upper pendulum bar 3 immediately, upper pendulum bar interlock wiper blade holder 6 makes the scraping blade 2 that is fixed on wiper blade holder 6 swing on the curved surface of face shield face screen 1, to realize removing the function of fog.
