Description
Technical Field
The invention relates to the technical field of protective articles, in particular to a protective hood.
Background
There is a threat to the human society against infectious diseases that can be transmitted through air or contact (new coronary pneumonia and the like appear in the years today). Particularly, first-line rescue personnel need to directly contact with pathogens, and wearing protective articles is particularly important for protecting the safety of the personnel. The invention provides a positive pressure biological protection hood (patent number: 201410747499.2), which realizes simple wearing of the protection hood, and because the air supply device of the protection hood needs a mobile power supply, and the mobile power supply and an air supply fan of the protection hood are both arranged in a shell formed by combining an upper shell of an air supply system and a lower shell of the air supply system, the mobile power supply is a storage battery, and if the storage battery leaks in the using process, toxic substances in the storage battery can be formed into toxic gas which enters the respiratory system of a wearer through the air supply fan, thereby causing great harm to human bodies.
Disclosure of Invention
In view of the above technical problems, the present invention provides a protective hood, which can be worn by a human body easily and can effectively prevent a wearer from being injured by toxic gases generated after a storage battery leaks.
The technical scheme is as follows: the utility model provides a protective head cover, its includes the hood body and air supply arrangement, the hood body with connect its characterized in that through the blast pipe between the air supply arrangement: the air supply device comprises a shell, an air supply fan is arranged in the shell, an air outlet is formed in the shell corresponding to the air supply fan, the air supply pipe is connected with the air outlet, and the battery box is connected with the shell.
It is further characterized in that said battery compartment is sealingly connected to said housing; the shell is an open shell, and the battery box is a shell cover plate; the shell is connected with the filter tank; a connecting strap is arranged on the shell or the battery box body; the blast pipe is arranged at the rear end of the head cover body; the rear end of the head cover body is provided with a drainage cover; the head cover body is connected with a cape.
By adopting the structure, the battery box is connected with the shell, so that the battery box is separated from the shell, and the battery is placed in the battery box, thereby effectively preventing toxic gas generated after the leakage of the storage battery from being input into the hood through the air supply fan to cause injury to a wearer.
Drawings
FIG. 1 is a front schematic view of a protective head cover of the present invention;
fig. 2 is an exploded view of the blower.
Detailed Description
The invention is further explained below with reference to the figures and examples.
Fig. 1, a protective head cover, it includes the hood body 1 and air supply arrangement 2, the hood body 1 is connected the scarf 3, the hood body 1 is connected through blast pipe 4 with air supply arrangement 2 within a definite time, air supply arrangement 2 includes casing 5, be provided with air supply fan 6 in the casing 5, it is provided with air outlet 7 to correspond air supply fan 6 on the casing 5, air outlet 7 is connected to blast pipe 4, casing 5 is connected to battery case 8, casing 5 is respectively through two filter tanks 10 of threaded connection (also can adopt other modes to connect), the battery is placed in the battery case, realize air supply fan and battery separation, the toxic gas that produces after effectively preventing the battery leakage causes the injury to the person of dress in passing through air supply fan input hood.
The preferred casing 5 is the open-type casing, and air supply fan 6 and control circuit board 11 set up in the casing, and battery case 8 is the casing apron, has realized through battery case 8 and casing 5 connection that the casing is covered tightly, has realized battery box body and casing separation simultaneously to battery in the battery box has been realized with the air supply fan separation in the casing.
Battery case 8 and 5 sealing connection of casing to realize the isolation of battery and air supply fan better, further prevented that the toxic gas that produces after the battery leaks from leading to the fact the injury to the wearer in the hood through air supply fan input.
The blast pipe 4 is arranged at the rear end of the hood body 1, so that the operation of wearing the protective hood for rescuing and the like is more convenient.
The rear end of the head cover body 1 is provided with a drainage cover 12, which ensures that the gas exhaled by the human body is rapidly discharged out of the body.
The shell 5 is provided with a switch 14, an air volume control switch 15 and an electric quantity display port 16, and the switch and the air volume control switch realize the control of the power switch and the air volume through a control module on a related control circuit board 11.
The working principle of the invention is described below with reference to the accompanying drawings:
see fig. 1, fig. 2, air supply fan 6 and control circuit board 11 set up in the casing, battery case 8 is the casing apron, it is tight to have realized the casing lid to be connected with casing 5 through battery case 8, battery box body and casing separation have been realized simultaneously, thereby battery in the battery box and the air supply fan separation in the casing have been realized, connect control circuit board 11 through wire or conducting metal piece in the battery box, when battery 13 puts into the battery case, the battery supplies power for control circuit board 11, control circuit board 11 controls the work of air supply fan 6, air supply fan 6 will be through the filterable fresh air of filter tank 10 and supply the human body to breathe in sending into the hood body 1 through blast pipe 4 and use.
During the use, set up the braces on air supply arrangement's casing or the battery case, also can put into air supply arrangement with air supply arrangement complex knapsack in, the personnel carry air supply arrangement on one's body, take the protection hood body and just can realize wearing the protection hood simply and carry out work, the protection hood provides the protection factor who is far above ordinary mask and hood, not only can keep apart personnel and polluted environment completely, can provide clear mobile air for inside through clean ambient air, higher security and travelling comfort have.
The present invention and its embodiments have been described in detail, without limitation, and the accompanying drawings are only one embodiment of the invention, and the actual structure is not limited thereto, so long as those skilled in the art can design the structure and the embodiments similar to the above technical solution without departing from the spirit of the invention.
