Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.
[0032] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.
[0033] In the embodiments of the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0034] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0035] See also Figure 1 to Figure 5 As shown, an embodiment of the present application discloses an integrated respiratory protection face shield, comprising a helmet shell 1 and a mask 2 rotatably connected to the helmet shell 1, characterized in that the helmet shell 1 is provided with a filter 3 at the back of the head, an air supply channel 11 is provided in the top of the helmet shell 1, an air inlet of the air supply channel 11 is connected to the filter 3, a first air outlet 111 of the air supply channel 11 is arranged on the inner side of the mask 2, and an air supply motor 4 is provided in the air supply channel 11.
[0036] By arranging a filter 3, an air supply motor 4 and an air supply channel 11 at the back of the helmet shell 1, the air at the rear of the helmet shell 1 is filtered and then transmitted to the front of the helmet, thereby effectively improving the breathing environment of the wearer.
[0037] Moreover, due to the presence of the air supply motor 4, the wearer can directly feel the wind from the front, providing a better breathing environment. The wind blown out through the first air outlet 111 can also blow away hot air and some toxic gases, providing a better breathing environment for the wearer.
[0038] The mask 2 may be a transparent mask 2 .
[0039] In this embodiment, the air supply channel 11 is located at the top of the head and is provided with a second air outlet 112 connected to the air supply channel 11. The second air outlet 112 can be a hole directly buckled on the air supply channel 11 as an air outlet. By providing the second air outlet 112, it is convenient to cool down the top of the head and avoid the stuffiness of the top of the head caused by long-term wearing.
[0040] Of course, the second air outlet 112 may also have other structures. For example, a second air outlet structure 113 is recessed in the air supply channel 11 at the top of the head, and a second air outlet 112 connected to the air supply channel 11 is provided on the side of the second air outlet structure 113 facing the mask 2.
[0041] Furthermore, the longitudinal section of the second air outlet structure 113 along the central axis of the helmet shell 1 is a right triangle, and the hypotenuse of the right triangle faces the side of the mask 2. Through the concave triangular column structure of the second air outlet structure 113, the wind in the air supply channel 11 is more likely to enter the second air outlet 112.
[0042] In this embodiment, the outer side wall at the rear end of the helmet shell 1 is connected to the air supply channel 11 and has a mounting hole 12, and a receiving box 13 for receiving the filter 3 is fixed on the mounting hole 12. The receiving box 13 is convenient for receiving and fixing the filter 3, and the receiving box 13 can be removed to check whether there is blockage in the air supply channel 11.
[0043] The containing box 13 includes a box body 131 for containing the filter 3 and a ventilation plate 132. The box body 131 is detachably connected to the mounting hole 12, and the ventilation plate 132 is detachably connected to the box body 131. Ventilation holes are provided on the box body 131 and the ventilation plate 132. The box body 131 and the ventilation plate 132 are detachable, and the filter 3 can be replaced regularly, which is simple and convenient to operate.
[0044] The ventilation hole structure on the box body 131 and the ventilation plate 132 can be formed by surrounding horizontal and vertical reinforcing ribs to ensure that the wind outside the helmet shell 1 can pass through the ventilation plate 132, the filter 3 and the box body 131 in sequence to enter the air inlet of the ventilation channel 11, and then achieve rapid ventilation through the air supply motor 4 to blow the air out of the first air outlet 111 and the second air outlet 112.
[0045] In this embodiment, the air supply motor 4 is fixed to the side of the helmet shell 1, the air supply blades of the air supply motor 4 are arranged in the air supply channel 11, and the side of the helmet shell 1 is provided with a switch 5 for controlling the start and stop of the air supply motor 4. The air supply motor 4 and its switch 5 are arranged on the side to facilitate starting or stopping the air supply motor 4.
[0046] Among them, a lighting lamp 6 is embedded in the front part of the helmet shell 1. The lighting lamp 6 is convenient for lighting in dark conditions. Specifically, the lighting lamp 6 is also provided with a switch, for example, by pressing the entire lighting lamp 6 to turn on or off the lighting lamp 6, so that the outer shape of the helmet shell 1 has no other holes and protrusions, ensuring the beautiful appearance.
[0047] Wherein, protective earmuffs 7 are arranged on the left and right sides of the helmet shell 1. By arranging the protective earmuffs 7, noise pollution can be prevented.
