Anti-pressure change earmuff structure

The present invention relates to an earmuff structure that is resistant to pressure changes and is an accessory that is adapted to be worn on the head for protecting the ear from physical stress caused by transient pressure changes.

Generally, modern people choose to relax in the holiday. If they choose to go to the mountains or travel abroad, the air pressure is usually small because of the high altitude or flying to the sky, which causes people to feel uncomfortable in the ear. There are people who can make progress.
The position where the general pressure change is most directly uncomfortable is the ear, and the conventional earmuff (the accessory for protecting the ear), such as the "head-mounted hot and cold device" of the Republic of China Patent Application No. 103207577, generally only It is used to adjust the temperature change (such as the temperature drop to keep the ear warm), and the adjustment function for the change of air pressure is not seen.
In view of the above-mentioned shortcomings, the inventor believes that it has the urgent need to make corrections, and that it has been engaged in the design and manufacture of related products for many years, and has always adhered to the excellent design concept, and researched and created the above disadvantages. After continuous efforts, the earmuff structure of the present invention for preventing pressure changes is finally introduced, which improves the efficacy of the product by correcting the excellent product structure.

The primary object of the present invention is to provide an earmuff structure that prevents changes in air pressure.
For the purpose of the foregoing disclosure, the ear pressure protection structure of the present invention comprises an ear cover and a gas pressure adjusting device, and the ear cover is mainly composed of a cover body, a connecting body, an ear chamber and a passage, and the number of the cover body is The ear chamber is provided with two joints, and the corresponding inner side of the cover body is recessed with the ear chamber, and the cover body is further provided with a passage for connecting the ear chamber to the outer side. The air pressure adjusting device is installed in the passage, and is mainly composed of a pressure regulating valve and a controller. The pressure regulating valve is installed in the passage of the two shells, and the pressure regulating valve has a hole, the hole The outer portion can communicate with the passage and the ear chamber, and the hole is provided with a cone block having a tapered surface conforming to one end of the hole, the pressure regulating valve is connected with the controller, and the controller is used for At the same time, the pressure regulating valve in the two hoods is controlled to open or close the cone in the pressure regulating valve. When the cone is closed, the ear chamber can be sealed, and the cone can be opened to make the ear chamber communicate with the outside. Through the tiny gap, the user can easily adapt to the air pressure, and then Changes in air pressure adjustment to help the wearer to improve the human body does not apply to changes in air pressure generated by the ear and achieve ever No effect.

FIG. 5 is a partial cross-sectional view showing the open state of the ear cover of the present invention.

The present invention relates to an earmuff structure that is resistant to pressure changes, [see the first figure] mainly comprising:
An earmuff (1) is mainly composed of a cover body (11), a joint body (12), an ear chamber (13) and a passage (14). The cover body (11) is provided with two and symmetrical to each other. The two shells (11) are connected by the connecting body (12), and the corresponding inner side of the shell body (11) is recessed with the ear chamber (13), and the ear chamber (13) The outer surface of the opening has a bonding surface (131) for conforming to the head of the user, and the bonding surface (131) can be provided with a cushion (132), which can be effectively To ensure that the inside of the ear chamber (13) is closed, the cover (11) is further provided with a passage (14) which allows the ear chamber (13) to communicate with the outside, and in the passage (14) ) Built-in air pressure adjustment device (2);
The air pressure adjusting device (2), [please refer to the second figure together] is mainly composed of a pressure regulating valve (21) and a controller (22), and the pressure regulating valve (21) is installed in two covers ( 11) in the passage (14), and the pressure regulating valve (21) is located outside the cover (11), the pressure regulating valve (21) has a hole (211), the hole (211) makes the outside The hole (211) is connected to the channel (14) and the ear chamber (13), and the hole (211) is provided with a cone (212) having a tapered surface conforming to one end of the hole (211). The pressure regulating valve (21) is connected to the controller (22), and the controller (22) is installed in one of the covers (11), and the controller (22) is laterally covered. A button (221) is provided outside the body (11) for operation control, which can simultaneously control the pressure regulating valve (21) in the two shells (11), and the cone (212) in the pressure regulating valve (21) Turn it on or off.
The earmuff structure for preventing pressure change of the present invention, [refer to the third figure], when the wearing is used, the two covers (11) are respectively covered outside the ear, so that the ear can be located in the ear chamber (13). The bonding surface (131) or the cushion (132) can be attached to the periphery of the ear to seal the ear chamber (13).
The earmuff structure for preventing pressure change according to the present invention is suitable for use in the case of having a pressure change (for example, when traveling through a mountain or flying at a high altitude), [refer to the third figure] the air pressure adjusting device (2) is permeable control (221) button (221) to adjust the earmuff (1) to be closed or open, [see the fourth figure] If the earmuff (1) is closed, the cone in the pressure regulating valve (21) The tapered surface between the block (212) and the hole (211) is fitted to communicate with the outside through the closed passage (14), so that the ear chamber (12) can be maintained at the original air pressure, [see Fig. 5] if the ambient pressure After the change, the earmuffs (1) are opened, and the cones (212) in the pressure regulating valve (21) are gradually separated from the holes (211), so that the cones (212) and the passages (14) and the holes (211) There is a slight gap between them, which allows the ear chamber (12) to communicate with the outside, and because the gap is relatively small, the user can be gently adapted to the air pressure.
The earmuff structure of the present invention for preventing pressure changes has the advantage that the structure is closed or opened by the pressure regulating valve to prevent an instantaneous pressure change from causing discomfort to the human body.
In summary, it is understood that the present invention is novel, and the present invention is not found in any publication, and is in compliance with the provisions of Articles 21 and 22 of the Patent Law.
The above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto. That is, the equivalent changes and modifications made by the invention in accordance with the scope of the invention are still within the scope of the invention.
