Embodiment 1

[0027] Such as Figure 1-3 As shown, a pressure-type personal protective mask of this embodiment includes a mask body 1 and a host 2. The mask body 1 includes a headgear 101 that is placed on the head of a human body. The front side of the headgear 101 is provided with a Front panel 102, the front panel 102 is provided with intake and exhaust nozzles 103 corresponding to the mouth of the human body; the main frame 2 is provided with a filter box 201 for filtering air, and the air outlet of the filter box 201 passes through the air duct 3 and the headgear 101 connected. When in use, the main unit 2 can be placed behind the waist, and when dealing with critically ill patients, virus infection when the mouth-to-mouth is close is avoided. one

[0028] The present invention is simple in structure, can filter the external air through the filter box 201 of the host 2 during normal use, and then enter the mask body 1 through the air duct later for people to use, and can also directl...

Embodiment 2

[0030] This embodiment is a further improvement made on the basis of Embodiment 1. The specific differences between this embodiment and Embodiment 1 are:

[0031] What needs to be further explained in this embodiment is that the rear portion of the headgear 101 is provided with a zipper, and the opening and closing of the headgear 101 when wearing the headgear 101 is realized through the zipper, and the zipper is pulled open when the headgear 101 is worn. The opening is relatively large, which is convenient for wearing the headgear 101 on the head. After wearing the headgear 101, the zipper is closed to realize sealing.

Embodiment 3

[0033] This embodiment is a further improvement made on the basis of Embodiment 1 or Embodiment 2. The specific differences between this embodiment and Embodiment 1 or Embodiment 2 are:

[0034] What needs to be further explained in this embodiment is that elastic bands 104 are provided on both sides of the top of the headgear 101, and each elastic band 104 is detachably connected with the headgear 101 through a buckle 105, which is convenient for disassembly and replacement, and the two elastic bands One end of 104 is all connected with front panel 102 by connecting seat 106, is convenient to carry out fine-tuning to front panel 102 after putting on headgear 101, for example can fine-tune and make front panel 102 keep certain gap with human face, can make comfort more like this powerful. The buckle 105 can be, but not limited to, a snap button commonly used on existing clothes. Existing masks are not only prone to indentation when worn for a long time, but are also prone to ...

Abstract

The invention belongs to the technical field of masks, and discloses a pressure type personal protective mask. The mask comprises a mask body and a main machine, wherein the mask body comprises a head sleeve arranged on the head of a human body in a sleeving mode, a front panel corresponding to the face of the human body is arranged on the front side of the head sleeve, an air inlet and outlet nozzle corresponding to the mouth of the human body is arranged on the front panel, a filter box for filtering air is arranged on the main machine, and an air outlet of the main machine communicates with the head sleeve through an air pipe. The mask is simple in structure, external air can be filtered through the filter box of the main machine during use at ordinary times, then the external air enters the mask body through the air pipe, positive air pressure is kept in the mask, negative air pressure is kept in the mask when a patient uses the mask, harmful germs of the patient cannot be spread to other people, and the mask is suitable for personal protection under the condition of strong infectious viruses.

Description

technical field [0001] The invention belongs to the technical field of masks, in particular to a pressure-type personal protection mask. Background technique [0002] The protective mask can filter the air entering the human respiratory tract. After wearing the protective mask, the user can effectively prevent the mouth or nasal cavity from inhaling harmful substances in the air, thereby reducing the threat of air pollution to human health. Most of the existing protective face shields are too simple in structure, and the filtering effect is not very good; and the full protection face shield often causes the phenomenon of face mask water mist while breathing, which is also unfavorable for the use of the face shield. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the purpose of the present invention is to provide a pressure type personal protective mask. [0004] The technical scheme adopted in the present invention is: ...
