Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

In the description of the present invention, it is to be understood that the terms "first", "second" and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the description of the present invention, it should be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly connected" to another element, there are no intervening elements present.

As shown in figure 1, the disposable breathable protective head cover comprises a head cover 1, a ventilation pipeline 24, a ventilation device 2, an N95-grade mask filter film 3 and a water absorption film. A second air inlet 11 is provided at the rear of the hood 1. The hood 1 is medical TUP transparent film or other transparent medical materials, and hood 1 top material thickness is greater than hood 1 peripheral material thickness, and the hood 1 lower part is provided with protection scarf 9, and hood 1 is provided with free elasticity area 4 and constraint device 8 in the department of linking to each other with protection scarf 9. The elasticity can be adjusted to free elasticity elastic webbing 4, has improved the leakproofness of protection headgear, has improved user's comfort level when increasing the isolation effect to the virus. The binding device 8 is used in cooperation with the ventilation fan 23, and when the ventilation fan 23 is opened, the binding device 8 is properly released, so that air can only be exhausted from the lower part of the protective headgear. When the ventilating fan 23 is closed, the binding device 8 can make the protective head cover form a relatively closed space to isolate virus. The interior of the hood 1 may be divided into a viewing area 7 and a water-absorbing area 6. The visual area 7 provides a certain visual field for the user, which is convenient for the user to work. The area 6 that absorbs water is provided with the film that absorbs water, and the film that absorbs water can absorb the inside steam of hood 1, plays the effect of the inside air of dry hood 1, prevents that the inside water smoke that produces of hood 1 from influencing user's eyesight scope. The fixing device 5 is used for fixing the ventilation device 2, the fixing device 5 is designed in a strap type, the fixing device 5 is provided with a fixing strap 51, and the fixing strap 51 can fix the ventilation device 2 on the shoulder of a user, so that the user can walk conveniently in the work process. While positioning the attachment points on the user's shoulder shortens the length of the airway tube 24, thereby enhancing the air delivery capability of the airway tube 24.

As shown in fig. 2, the ventilation device 2 includes a ventilation fan 23 and a ventilation box 25, and the ventilation fan 23 is provided with a controllable switching device and a gear shifting device. The ventilating fan 23 can be reused after being sterilized and charged. Both faces of the ventilation box 25 are provided with the first air inlet 21 and the first air outlet 22, respectively. The upper end of the ventilation duct 24 is communicated with the second air inlet 11 of the hood 1, and the lower end of the ventilation duct 24 is communicated with the first air outlet 22 of the ventilation box 25. In air pipe 24 carried the air after filtering to the protection headgear, formed the air curtain, prevent that the virus from getting into inside the protection headgear, enhanced security, increased the inside gas circulation of protection headgear simultaneously, the moist gas that the air that flows exhaled the user drives out the protection headgear, improves the gas permeability and the nice and cool nature of protection headgear. The first air inlet 21 of the ventilation box 25 is connected with the N95-level mask filter membrane 3, and a certain distance is reserved between the N95-level mask filter membrane 3 and the ventilation fan 23, so that huge noise generated when the ventilation fan 23 operates can be avoided. The N95-grade mask filter film 3 can be replaced regularly, so that the safety and the service time of the protective headgear are increased.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention; it should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention, and therefore the scope of the patent of the invention is to be defined by the appended claims.
