Description

Novel protective cap

Technical Field

The utility model relates to a public health technical field, more specifically relates to a novel helmet.

Background

Under the background of the pandemic of respiratory infectious diseases, in order to protect individuals, people need to wear protective articles such as masks and goggles when going out, disposable masks need to be replaced in time, along with respiratory infectious disease cases in more and more countries and regions, the masks are seriously insufficient in supply and extremely short, and a large amount of medical wastes are generated after the used masks are discarded, so that the environment is polluted; in addition, wearing the mask causes inconvenience to daily life of people and even harm to facial skin, and children, old people and patients with cardiovascular diseases are not suitable for wearing high-density masks.

In order to reduce the spread of respiratory infectious diseases, and to solve the above problems, a novel protective cap which is convenient to use is urgently needed in the field.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel technical scheme of novel helmet.

The utility model provides a novel protective cap, including the cap body, PM1.0 cutting head, silent fan, lithium cell, fan switch, brim of a hat perforated pipe and air duct, PM1.0 cutting head includes top cap, antibiotic filter membrane and filter membrane dish, the lithium cell can be dismantled to get off and utilize alternating current power supply to charge or directly charge on the cap, also can utilize solar cell panel to charge. The utility model discloses novel helmet through the silence fan intake air, through the air duct, again by the brim of a hat through the downward blowout of perforated pipe, form round protection air curtain around the person's of wearing head, can block the droplet furthest, reduce respiratory infectious disease's propagation, in addition, the utility model discloses helmet has cold-proof and rain-proof function concurrently simultaneously.

Preferably, the PM1.0 cutting head and the mute fan are arranged at the top of the cap body, the PM1.0 cutting head comprises a top cover, an antibacterial filter membrane and a filter membrane disc, and the antibacterial filter membrane can adopt a nanofiber antibacterial filter membrane with a pore size of 100-500 nm.

Preferably, there are two lithium batteries, set up in cap body both sides for the silence fan power supply.

Preferably, the brim perforated tube is oval-shaped, and all holes are open downwards.

The utility model provides a novel helmet can used repeatedly, the lithium cell can be dismantled and get off to utilize alternating current power supply to charge or directly charge on the cap, also can utilize solar cell panel to charge, and resources are saved reduces the energy consumption.

Other features of the present invention and advantages thereof will become apparent from the following detailed description of exemplary embodiments of the invention, which proceeds with reference to the accompanying drawings.

Example 1

Referring to fig. 1 and 2, the present embodiment provides a novel helmet.

This novel helmet includes PM1.0 cutting head 1, silence fan 2, lithium cell 3, fan switch 4, brim of a hat perforated pipe 5, the cap body 6 and air duct 7.

A top cover 11, an antibacterial filter membrane 12 and a filter membrane disc 13 are arranged in the PM1.0 cutting head 1.

When the protection cap of the utility model is needed to be opened, the fan switch 4 is pressed, the mute fan 2 is started to press the air into the cap body, the PM1.0 cutting head top cover 11 prevents most particles with the particle size larger than 1.0 micron from entering the cap body, the antibacterial filter membrane 12 further filters fine particles, bacteria and viruses in the air, the filtered air is shunted by the air duct 7 and then is sprayed downwards by the cap edge perforated pipe 5, a circle of protective air curtain is formed around the head of the wearer to protect the hair, eyes, nasal cavity and oral cavity of the wearer, when the spray impacts the protective air curtain from the outside, the spray is bounced or guided to the ground by the air flow, if the patient wears the protection cap, the spray generated by the patient firstly impacts the inner side of the protective air curtain, most of the spray is directly guided to the ground, and the rest part of the spray reaches the nearby normal person, the protective air curtain is impacted from the outside again, that is to say, the spray passes through two protective air curtains on the transmission path from the patient to the normal person, thereby stopping the spray transmission to the maximum extent, the mute fan 2 adopts two lithium batteries 3 to supply power, the lithium batteries 3 are arranged at the symmetrical positions of the two sides of the cap body, and the lithium batteries can be disassembled to be charged by using an alternating current power supply or directly charged on the cap.

Although certain specific embodiments of the present invention have been described in detail by way of example, it should be understood by those skilled in the art that the foregoing examples are for purposes of illustration only and are not intended to limit the scope of the invention. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.

Example 2

Referring to fig. 3, the present embodiment provides another novel protective cap, which is different from embodiment 1 in that a solar cell panel 8 is added to the brim of the cap body 6 of the present embodiment, and the novel protective cap can be placed under sunlight to charge a lithium battery 3 by using solar energy, and the rest is the same as embodiment 1.
