Description

Electric air supply filter protective hood

technical field

The invention relates to the field of medical instruments, in particular to an electric air supply filter type protective headgear.

Background technique

At present, people still generally use the method of wearing a "mask" to prevent the infection of infectious diseases, but the effect of this method is not ideal. Even if the number of layers and thickness of the mask is greatly increased, the effect is still very poor. . Especially for the prevention of severe infectious diseases, the effect is even worse, so that many medical staff are infected, and some even sacrifice their precious lives. This is because even if people wear a thick "mask", its sealing performance is not good. On the one hand, infectious viruses can still be inhaled into the body along the gaps around the mask, causing diseases; on the other hand , Although masks can filter out a large number of viruses, these large amounts of viruses are still attached to the masks and can enter the human body at any time, causing human infection, which is very dangerous. Because the hospitals and wards are filled with a large number of viruses, it is extremely easy to cause cross-infection with each other, so that sometimes the rapid spread of the disease will occur, and even more and more patients will be treated. The terrible situation that cannot be controlled. This will greatly endanger human health and social development.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide an electric air supply filter type protective hood, which has a simple structure, good sealing performance, convenient take off and put on operation, and optimized comfort.

In order to achieve the above object, the present invention provides an electric air supply filter type protective hood, comprising a transparent hood body and an inflatable sealing base detachably mounted on the bottom of the hood body; wherein,

A cavity with an open bottom is formed in the headgear body, and the headgear body can be sleeved on the head from the top of the user's head to the direction of the neck;

The bottom of the hood body is formed with an annular transverse zipper, the sealing base is connected to the hood body through the transverse zipper, and when the sealing base is inflated, it can be tightly sleeved on the neck of the user to close the cavity;

The head cover body is provided with at least two ventilation holes, and the ventilation holes are detachably installed with a connecting head that can be connected with the electric blower. The inner thread of the air blower pipeline is connected, and the outer wall of the connecting head is formed with an outer thread that is threadedly connected with the sealing cover.

Preferably, the headgear body is provided with longitudinal openings, and the longitudinal openings are sealed by longitudinal zippers or buckles.

Preferably, the extending direction of the longitudinal opening is from the top of the user's head to the chin.

Preferably, a cavity for accommodating the user's long hair is provided on the headgear body at the back of the head.

Preferably, the transverse zipper and/or the longitudinal zipper are invisible zippers.

Preferably, at least two ventilation holes are symmetrically arranged on both sides of the hood body.

Preferably, the thickness of the hood body at the position in front of the user's eyes is smaller than the thickness of the rest of the hood body.

Preferably, a receiving pocket for inserting the name tag is formed on the headgear body at the back of the head.

According to the above technical solution, the present invention installs the inflatable sealing base on the bottom of the transparent hood body, and forms an annular transverse zipper at the bottom of the hood body, and the sealing base is connected to the hood body through the transverse zipper, and when After being inflated, the sealing base can be tightly sheathed on the neck of the user to close the cavity. When in use, put the headgear body on the user's head and inflate the sealing base, so that the sealing base is bulged to fill and surround the user's neck, so that the overall sealing performance is better, the safety performance is higher, and the gas No leakage occurs when passing through the space between the user's head and the headgear body, which improves the use efficiency of the blowing gas. When the hood needs to be removed, it is only necessary to release the gas in the sealing base, and then take it off from the neck after it is loosened. The head cover body is provided with at least two ventilation holes, and the ventilation holes are detachably installed with a connecting head that can be connected with the electric blower. The inner thread of the air blower pipeline is connected, and the outer wall of the connecting head is formed with an outer thread that is threadedly connected with the sealing cover. Through the connector, the ventilation holes can be completely closed when the hood is not in use, so as to prevent the external air from polluting the inner filter, and the hood and the air supply mechanism can be quickly disassembled and connected, and the use efficiency is better.

Other features and advantages of the present invention will be described in detail in the detailed description that follows.

Detailed ways

The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.

In the present invention, unless otherwise stated, the orientation words such as "upper, lower, inner, outer" included in a term only represent the orientation of the term under normal usage, or are understood by those skilled in the art and should not be viewed as a limitation of the term.

Referring to Fig. 1, the present invention provides an electric air supply filter type protective hood, comprising a transparent hood body 1 and an inflatable sealing base 3 detachably mounted on the bottom of the hood body 1; wherein,

A cavity with an open bottom is formed in the headgear body 1, and the headgear body 1 can be sleeved on the head from the top of the user's head to the direction of the neck;

The bottom of the hood body 1 is formed with an annular transverse zipper 2, the sealing base 3 is connected to the hood body 1 through the transverse zipper 2, and when the sealing base 3 is inflated, it can be tightly sleeved on the user's neck to seal cavity;

The head cover body 1 is provided with at least two ventilation holes, and the ventilation holes are detachably installed with a connecting head that can be connected with the electric blower. A filter 7 is embedded in the connecting head, and an inner wall of the connecting head is formed with a The inner thread 6 connected with the pipeline of the electric blower is formed with an outer thread 5 which is threadedly connected with the sealing cover on the outer wall of the connecting head.

Through the above technical solution, the inflatable sealing base is installed on the bottom of the transparent hood body, an annular transverse zipper is formed at the bottom of the hood body, the sealing base is connected to the hood body through the transverse zipper, and when the sealing base is After inflation, it can be tightly sleeved on the user's neck to close the cavity. When in use, put the headgear body on the user's head and inflate the sealing base, so that the sealing base is bulged to fill and surround the user's neck, so that the overall sealing performance is better, the safety performance is higher, and the gas No leakage occurs when passing through the space between the user's head and the headgear body, thereby improving the use efficiency of the blowing gas. When the hood needs to be removed, it is only necessary to release the gas in the sealing base, and then take it off from the neck after it is loosened. The head cover body is provided with at least two ventilation holes, and the ventilation holes are detachably installed with a connecting head that can be connected with the electric blower. The inner thread of the air blower pipeline is connected, and the outer wall of the connecting head is formed with an outer thread that is threadedly connected with the sealing cover. Through the connector, the ventilation holes can be completely closed when the hood is not in use, so as to prevent the external air from polluting the internal filter, and the hood and the air supply mechanism can be quickly disassembled and connected, and the use efficiency is better.
