Description

Technical Field

[0001] The present invention relates to the technical field of masks, and specifically to a waterproof mask with self-adjustable air permeability effect. Background Art

[0002] The structures and functions of existing masks are relatively simple. Usually, masks with good waterproof performance have poor air permeability, and it is impossible to ensure both waterproofness and air permeability at the same time. When using a mask with good wind resistance for high-speed cycling, at low speed, the air permeability of the mask is not good enough. Therefore, how to solve the wind resistance of the mask in a high-speed environment and ensure the air permeability in a low-speed state, and be able to adapt to rainy environments is the main problem to be solved by this device. Summary of the Invention

[0003] The purpose of the present invention is to provide a waterproof mask with self-adjustable air permeability effect to overcome the above-mentioned defects in the prior art.

[0004] The present invention is realized through the following technical solutions.

[0005] A waterproof mask with self-adjustable air permeability effect of the present invention includes a mask and ear hooks. The mask includes a filter layer. A thermal insulation layer is provided inside the filter layer, an inner waterproof layer is provided outside the filter layer, an elastic baffle is provided outside the inner waterproof layer, an outer waterproof layer is provided outside the elastic baffle. A cavity is formed between the inner waterproof layer and the outer waterproof layer. The inner waterproof layer and the inner waterproof layer are communicated with air holes. Waterproof scales are provided outside the outer waterproof layer. The waterproof scales are evenly distributed on the outer surface of the outer waterproof layer. An air permeability gap is formed between adjacent upper and lower waterproof scales. The waterproof scales are composed of a water-absorbing expansion layer and a waterproof elastic layer. The water-absorbing expansion layer faces outwards, and the waterproof elastic layer faces inwards. The water-absorbing expansion layer is composed of a water-absorbing expansion material, and the waterproof elastic layer is composed of a waterproof material. The elastic baffle is inclined downward.

[0006] In a further technical solution, longitudinal diversion grooves, oblique diversion grooves, and transverse diversion grooves are provided on the surface of the mask. The longitudinal diversion grooves are located in the middle of the mask and are longitudinally distributed. The oblique diversion grooves are located on both sides of the mask and are horizontally distributed. The transverse diversion grooves are located below both sides of the mask and are obliquely downward distributed.

[0007] In a further technical solution, an air pipe is provided on the upper side of the mask. A heat-conducting metal wire is provided inside the air pipe. An air vent is communicated with the lower side of the air pipe. The air vent is communicated with the cavity.

[0008] Further technical solution: One side of the ventilation pipe is communicatively connected with a heating resistance wire. A heat conduction rod is arranged inside the heating resistance wire, and a heating resistance wire is arranged inside the heat conduction rod. One side of the connecting pipe is provided with a blowing body, and blowing blades are arranged inside the blowing body. A handheld handle is arranged below the blowing body. The heat conduction rod can abut against the heat conduction metal wire.

[0009] Further technical solution: A rain shield is arranged below the mask, and a drain port is communicatively connected with the outside below the cavity.

[0010] Further technical solution: A connecting head is arranged at the lower end of the elastic baffle. A through groove is communicatively connected up and down in the connecting head, and the connecting head is connected with the outer waterproof layer.

[0011] Advantages of the present invention:

[0012] An air permeability effect self-adjusting waterproof mask of the present invention is provided with an outer waterproof layer, an inner waterproof layer, air holes, an elastic baffle, a cavity, etc. When the wind blows from the outside, the elastic baffle bends downward naturally, and the elastic baffle blocks the air holes of the inner waterproof layer. The greater the wind force, the greater the bending degree of the elastic baffle, and the more air holes the elastic baffle blocks, making it more difficult for the wind to penetrate the inner waterproof layer. Thus, the function of better air permeability with smaller wind force and poorer air permeability with larger wind force is achieved. This device is suitable for winter cycling, skiing and other sports.

[0013] An air permeability effect self-adjusting waterproof mask of the present invention is provided with waterproof scales, a water-absorbing expansion layer, a waterproof elastic layer, air-permeable gaps, etc. In non-rainy weather, the waterproof scales open naturally, and the distance of the air-permeable gaps is larger, facilitating ventilation. When it rains, the water-absorbing expansion layer absorbs water and expands, the water-absorbing expansion layer elongates, the volume of the waterproof elastic layer remains unchanged, the water-absorbing expansion layer drives the waterproof elastic layer to bend, and the waterproof elastic layer functions as waterproofing, and the distance of the air-permeable gaps decreases, thereby reducing the probability of rainwater entering the cavity through the air-permeable gaps.

[0014] An air permeability effect self-adjusting waterproof mask of the present invention is provided with a ventilation pipe, a heat conduction metal wire, a ventilation port, a drain port, etc. Hot air enters the cavity through the ventilation pipe, dries the residual moisture in the cavity and discharges it through the drain port, which is beneficial to quickly drying this device. On the one hand, the heat conduction metal wire can make this device fit the face, ensure that the cavity of the ventilation pipe does not bend, and ensure that air can pass through the entire cavity of the ventilation pipe. On the other hand, the heat conduction metal wire can conduct heat, avoid the air temperature at the distal end of the ventilation pipe from being too low, and play a role in uniformly heating the air.

[0023] The following will Figures 1-6 describe the present invention in detail. For the convenience of narration, the following directions are defined as follows: the up, down, left, right, front, and back directions mentioned below are consistent with the up, down, left, right, front, and back directions of the Figure 1 projection relationship of itself.

[0024] Combined with the attached Figures 1-6The described breathable effect self-adjusting waterproof mask includes a mask 10 and ear hooks 11. The mask 10 includes a filter layer 13. An insulation layer 12 is provided inside the filter layer 13. An inner waterproof layer 15 is provided outside the filter layer 13. An elastic baffle 14 is provided outside the inner waterproof layer 15. An outer waterproof layer 16 is provided outside the elastic baffle 14. An inner waterproof layer 15 and an outer waterproof layer 16 form a cavity 24. The inner waterproof layer 15 and the inner waterproof layer 15 are communicated with each other and provided with air vents 26. Waterproof scales 17 are provided outside the outer waterproof layer 16. The waterproof scales 17 are evenly distributed on the outer surface of the outer waterproof layer 16. An air permeable gap 20 is formed between adjacent upper and lower waterproof scales 17. The waterproof scales 17 are composed of a water-absorbing and swelling layer 18 and a waterproof elastic layer 19. The water-absorbing and swelling layer 18 faces outwards, and the waterproof elastic layer 19 faces inwards. The water-absorbing and swelling layer 18 is composed of a water-absorbing and swelling material, and the waterproof elastic layer 19 is composed of a waterproof material. The elastic baffle 14 is inclined downwards.

[0025] When wearing this device, the outside wind blows the outer waterproof layer 16, the outer waterproof layer 16 presses the elastic baffle 14, and the elastic baffle 14 naturally bends downwards. The elastic baffle 14 blocks the air vents 26 of the inner waterproof layer 15 inside. The outside wind enters the cavity 24 through the air vents 26 of the outer waterproof layer 16. The elastic baffle 14 blocks a part of the wind, and the remaining wind passes through the holes of the inner waterproof layer 15 and passes through the filter layer 13. The filter layer 13 filters air pollutants, and the insulation layer 12 plays a role in keeping warm. The greater the wind force, the greater the bending degree of the elastic baffle 14, and the more the air vents 26 of the inner waterproof layer 15 are blocked by the elastic baffle 14, and the more difficult it is for the wind to penetrate the inner waterproof layer 15. Thus, the function of the smaller the wind force, the better the air permeability, and the greater the wind force, the worse the air permeability is realized. This device is suitable for sports such as winter cycling and skiing. In the weather without rain, the waterproof scales 17 naturally open, and the distance of the air permeable gap 20 is larger, which is convenient for ventilation. When it rains, the water-absorbing and swelling layer 18 absorbs water and swells, the water-absorbing and swelling layer 18 elongates, the volume of the waterproof elastic layer 19 remains unchanged, the water-absorbing and swelling layer 18 drives the waterproof elastic layer 19 to bend, and the waterproof elastic layer 19 plays a waterproof function. All the waterproof scales 17 bend, and the distance of the air permeable gap 20 decreases, thereby reducing the probability of rainwater entering the cavity 24 through the air permeable gap 20.
