Description

Earmuff gas mask

This creation is about anti-drug products, especially an earmuff-type gas mask that can be worn comfortably by the user and does not affect the line of sight.

In general, people who are exposed to uncomfortable or toxic environments such as air polluted plants for long periods of time, in order to provide clean air source for mouth and nose breathing, will use gas masks, and the most common types are A full face mask.

However, since such a full-face mask prevents external air from entering the mask, the mask and the face are closely attached to each other, so that if the user wears it for a long time, it may cause pain and discomfort due to friction or the like. Moreover, as shown in FIG. 1 , it is a schematic view of a conventional gas mask. The general gas mask 2 is provided with a gas filter tank 21 close to the mouth and nose, but since the gas filter tank 21 has a certain volume, when used When wearing a gas mask due to the nature of work, some of the sights will be blocked by the protruding filter cans, which will cause inconvenience to work, and the conventional gas mask 2 is fixed to the head by means of a buckle or the like, so because of work The movement of the head causes the gas mask to rub against the face and the like, causing the user to feel pain and discomfort.

In view of this, the inventors feel that they have not perfected their efforts and painstakingly studied, and based on their accumulated experience in the industry for many years, and then provided an earmuff-type gas mask, in order to improve the lack of the above-mentioned conventional techniques.

One of the purposes of this creation is to provide an earmuff-type gas mask that allows the user to be comfortable when wearing and to be blocked from view when working, and to allow the user to receive the outside when wearing it. Information.

In order to achieve the above object, the earmuff type gas mask of the present invention comprises: two earmuff main bodies, each of which is provided with a gas filtering portion and a gas conveying port; and a wearing portion, the two ends of which are attached The earmuffs are connected to each other such that when worn on the head, the earmuffs cover the ears; a cover that is attached to the nose and mouth to block external air from entering, and the cover is provided with two An air inlet and an exhaust port; and two connecting pipes respectively connected to the connecting pipe are respectively connected to the gas conveying port and the air inlet to send the gas filtered through the filtering portion to the cover . The earphone body is further provided with a radio transceiver component and a sound source playing component, and the radio transceiver component and the sound source playing component are electrically connected to each other.

Moreover, the material of the connecting pipes is a memory alloy, and the material of the cover is a soft material. The filter units are detachable, allowing the user to replace the filter units more conveniently.

By the above means, the user can not hinder the operation because the protruding filter can cause the line of sight to be blocked, and it will not cause pain or discomfort after being worn for a long time, and can also enable the user to wear the earmuff after wearing the earmuffs. Receive external information via radio.

Figure 2 is an exploded view of the preferred embodiment of the present invention.

Figure 3 is a plan view of a preferred embodiment of the present invention.

Figure 4 is a schematic view showing the use of the preferred embodiment of the present invention.

In the following description, the same components are denoted by the same reference numerals for the sake of understanding, in order to make the understanding of the present invention clear.

Please refer to FIG. 2 and FIG. 3, which are exploded views and plan views of the preferred embodiment of the present invention. As shown in FIG. 2 and FIG. 3, the earmuff type gas mask 1 of the present invention comprises: two earmuffs body 11, a wearing portion 12, a cover 13 and two connecting tubes 14.

The earmuffs 11 are capable of blocking external noise. Each of the ear cups 11 is provided with a filter portion 111 and a gas delivery port 112, and the filter portion 111 can pass outside air through the interior of the filter portion 111. After filtration, clean air is sent to the cover 13 through the gas delivery port 112 for the user to breathe. The two ends of the headwear 12 are connected to the earmuffs body 11 so that the earmuffs 11 can cover the ears when worn on the head, so that the gas mask is utilized compared with the prior art. When the buckle is fixed to the head, the creation can be worn comfortably by the user without causing pain and discomfort due to friction or the like. The cover 13 is applied to the nose and mouth to block the entry of outside air, and the material of the cover 13 is made of a soft material such as rubber, so that the cover 13 can conform to various face shapes, and the user can comfortably In use, the cover 13 is provided with two air inlets 132 and an exhaust port 131 for the filtered clean air to enter the cover 13 from the air inlets 132 for the user to breathe and breathe. The exhaust gas is discharged to the cover 13 through the exhaust port 131. The connecting tubes 14 are respectively connected to the gas carrying port 112 and the air inlet 132 to send the gas filtered by the filtering unit 111 to the cover, and the connecting tubes 14 are made of a memory alloy. Therefore, the cover 13 can be preferably fixed to the face without causing the cover to be shaken. There is a gap between the body 13 and the face.

Please refer to FIG. 4, which is a schematic diagram of the use of the preferred embodiment of the present invention. As shown in FIG. 4, the method of using the present invention is to first wear the wearing part 12 on the head and cover the ear cover body 11 on the ear, and then cover the cover 13 on the nose and mouth, and The cover 13 can be fixed for breathing by slightly adjusting the position of the connecting tubes 14. When the filter portions 111 reach their service life or are damaged due to the internal filter structure, since the filter portions 111 are detachable, only the old ones need to be replaced when replacing the filter portions 111. The filter unit 111 is detached from the earmuffs 11 and the new filter portions 111 are inserted into the ear cups 11 to complete the replacement, which is very convenient, and in this embodiment, it is a snap type. The filter portions 111 can be easily disassembled in a snap-fit manner.

In addition, please refer to Figure 3. In a work environment with a lot of dust or harmful substances, such as factories, it is impossible to receive external information after wearing earmuffs. Whether or not an unexpected situation occurs, the present creator adds a radio transceiver component 113 and a sound source playback component 114 to the present creation, and sets the radio transceiver component 113 and the sound source playback component 114 to the earmuffs. The radio transceiver component 113 is electrically connected to the sound source playback component 114. In use, the radio transceiver component 113 receives an externally transmitted radio signal and converts the radio signal into a sound source. The signal is further transmitted to the sound source playing component 114 to play the content contained in the wireless signal to the user, so that the user can also know the external information through the radio when wearing the creative work.

However, the above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, so it is common knowledge in the technical field or equivalent or easy to be familiar with the technology. The changer, equal without the spirit and scope of the creation Changes and modifications are to be covered by the scope of this creation.
