Referring to fig. 1, 2 and 3, a helmet 10 with good ventilation performance includes a helmet body 20 and a ventilator 100, wherein the helmet body 20 has an outer shell 30. The inner wall of the helmet body 20 is provided with a ventilation layer 401, and an air diffusion layer 50 is arranged between the ventilation layer 401 and the outer shell 30. The ventilation layer 401 is provided with a plurality of air inlet holes 60, and the air inlet holes 60 are communicated with the air diffusion layer 50.
With continued reference to fig. 1, the ventilator 100 is disposed on the outer shell 30 of the helmet body 20, and the ventilator 100 is in communication with the air diffusion layer 50. Preferably, the ventilator 100 is provided on the top of the helmet body 20. The air-permeable layer 401 is provided with avoidance holes 70. Fresh air outside the helmet enters the air diffusion layer 50 through the ventilator 100, and after being diffused by the air diffusion layer 50, the fresh air uniformly enters the interior of the helmet body 20 through the air inlet holes 60.
With reference to fig. 1, it should be noted that the fresh air diffused by the air diffusion layer 50 enters the interior of the helmet body 20 through the air inlet holes 60, so that the speed of the fresh air entering the interior of the helmet body 20 is slow and mild, and the comfort of the helmet 10 with good ventilation performance is improved; after the helmet is worn by a wearer, fresh air can be smoothly breathed.
Referring to fig. 8 and 9, in particular, the ventilator 100 includes: knob 200, valve 300, and seal 400. The knob 200 is provided with a plurality of protrusions 210, the valve 300 is provided with a plurality of grooves 310, and the plurality of protrusions 210 and the plurality of grooves 310 are in one-to-one correspondence and are matched.
Referring to fig. 9 again, the sealing member 400 is provided with a switch post 410, the valve 300 is provided with a switch guiding groove 320, and the switch guiding groove 320 extends from the top near the valve 300 to the bottom near the valve 300 in an inclined manner. The switch post 410 is snapped into the switch guide slot 320. The valve 300 is closely attached to the sealing member 400 or separated from the sealing member 400.
Referring again to fig. 9, in particular, the switch post 410 is a cylinder. The knob 200 is provided with a first through hole 330, the sealing member 400 is provided with a second through hole 420, and the first through hole 330 and the second through hole 420 cooperate to form a ventilation channel (not shown in the figure) which is communicated with the interior of the helmet body 20. It should be noted that the switch guide groove 320 of the valve 300 is not a smoothly inclined structure, but is inclined stepwise. Thus, the switch post 410 is less likely to slip or shake in the switch guide groove 320 during ventilation, thereby ensuring stability of the ventilator 100.
Referring to fig. 4, 5, 6 and 7, in detail, the ventilator 100 further includes a filter 500 and an outer cover 600, the filter 500 is sleeved on an inner side wall of the outer cover 600, the outer cover 600 has a plurality of air vents 610 on a side wall thereof, and the valve 300 is connected to an inner top wall of the outer cover 600 through a spring 620.
Referring to fig. 8 and 9, in particular, the outer wall of the knob 200 has anti-slip ribs 220, and the anti-slip ribs 220 are distributed in an annular array around the center of the knob 200, so that the knob 200 is not easy to slip when rotated.
The ventilator 100 may be assembled in the following manner (see fig. 6, 7, 8 and 9):
assembling the sealing member 400 with the valve 300 such that the switch post 410 of the sealing member 400 is caught in the switch guide groove 320 of the valve 300;
assembling the valve 300 with the knob 200 such that the protrusions 210 of the sealing member 400 are snapped into the grooves 310 of the valve 300 in a one-to-one correspondence;
the filter is coupled to the inner sidewall of the outer cap 600.
Of course, when the ventilator 100 is assembled with the helmet body 20, the filter and the outer cap 600 are pressed against the outer sidewall of the helmet body 20. So that the air outside the helmet body 20 enters the ventilator 100 through the air vent 610, and the air outside the helmet body 20 enters the ventilator 100 and is first filtered through the filter, so that the air breathed by the wearer after wearing the helmet is kept clean.
It should be noted that the ventilation is adjusted by the wearer of the access hole 70 by adjusting the knob 200 of the ventilator 100 through the access hole 70. Therefore, as one preferable mode, the avoiding hole 70 is formed right under the ventilator 100, so that the adjustment of the knob 200 is more convenient.
The operation of the ventilator 100 will now be explained (please refer to fig. 6, 7, 8 and 9):
when the helmet 10 with good ventilation performance does not need to ventilate, the plurality of protrusions 210 of the sealing element 400 are correspondingly clamped into the plurality of grooves 310 of the valve 300 one by one, so that the knob 200 is rotated, the knob 200 drives the valve 300 to rotate, and one end, close to the top of the valve 300, of the switch guide groove 320 of the valve 300 is close to the switch column 410 of the sealing element 400 until one end, close to the top of the valve 300, of the switch guide groove 320 of the valve 300 abuts against the switch column 410 of the sealing element 400; at this time, the valve 300 is tightly pressed against the sealing member 400, and the air passing through the air vent 610 and the filter 500 in sequence cannot enter the air vent channel, so that the ventilator 100 is closed;
when the helmet 10 with good ventilation performance needs to ventilate, the plurality of protrusions 210 of the sealing member 400 are correspondingly clamped into the plurality of grooves 310 of the valve 300, and the switch guide grooves 320 of the valve 300 extend from the top part near the valve 300 to the bottom part near the valve 300 in an inclined manner; therefore, when the knob 200 is rotated, the knob 200 drives the valve 300 to rotate, such that the end of the switch guide groove 320 of the valve 300 close to the bottom of the valve 300 is close to the switch post 410 of the sealing member 400; the valve 300 is now separated from the seal 400; the air passing through the air vent 610 and the filter 500 in sequence enters the air vent channel from the separation gap between the valve 300 and the sealing member 400, thereby realizing air intake of the ventilator 100; of course, the air exhaled by the wearer can flow out of the helmet through the air inlet holes 60, the air permeable layer 401, the ventilation channel, the separation gap between the valve 300 and the sealing member 400, the filter element 500 and the ventilation hole 610 in sequence; thereby achieving ventilation of the outside and inside of the helmet 10 with good ventilation performance; but also can bring out the heat generated by the head of the wearer in the helmet in time, and ensure that the wearer of the helmet does not feel sultry when wearing the helmet;
it should be noted that, according to the amount of ventilation desired by the wearer, the position of the switch column 410 of the sealing member 400 in the switch guiding groove 320 of the valve 300 can be adjusted by rotating the knob 200, so as to achieve the effect of adjusting the amount of ventilation; when the ventilation amount needs to be reduced, the switch column 410 of the sealing member 400 is towards one end close to the top of the valve 300 by rotating the knob 200, so that the gap between the valve 300 and the sealing member 400 is reduced; when the ventilation quantity needs to be increased, the switch column 410 of the sealing member 400 is enabled to be towards one end close to the bottom of the valve 300 by rotating the knob 200, so that the gap between the valve 300 and the sealing member 400 is enabled to be enlarged;
it should be noted that, since the air vent 610 of the outer cover 600 is opened at the side wall of the outer cover 600, the air outside the helmet entering the ventilator 100 is not directly blown in, but is deflected to enter through the side wall of the outer cover 600; thus, the pressure of the air blown into the ventilator 100 against the front face of the ventilator 100 is greatly reduced;
furthermore, during venting, the gap between the valve 300 and the sealing member 400 is at the edge of the valve 300 and the sealing member 400, and the second through hole 420 of the sealing member 400 is opened at the middle of the sealing member 400; therefore, the air entering the inner part of the outer cap 600 enters the vent channel by turning to the edge of the valve 300 and then turning to the second through hole 420 at the middle part of the sealing member 400 at the edge of the sealing member 400; therefore, the air needs to be turned for three times in the entering process from the outside of the helmet to the inside of the helmet, so that the speed of the air flowing into the diffusion layer is greatly reduced, the air blown into the helmet is slow, mild and uniform, and the comfort of the helmet 10 with good ventilation performance is greatly improved; the ventilator 100 is only a small part relative to the helmet 10 with good ventilation performance, and the ventilator 100 is arranged on the helmet body 20 in a penetrating manner, so that the rigidity of the helmet body 20 is not affected, and the protection performance of the helmet 10 with good ventilation performance is ensured.
In addition, it is also noted that, due to the increasing environmental pollution, the harm of harmful substances in the air to human bodies is an important aspect affecting human health. The ventilator 100 of the present invention filters air by the filter 500, and filters out harmful substances, sand, mosquitoes, etc., thereby ensuring clean, healthy, and safe air blown into the helmet. Referring to fig. 7 and 8, it should be noted that the filter 500 includes a filter frame 630 and a filter cotton 640 detachably disposed on the filter frame 630. The filter 500 is easy to install and disassemble. After a period of use, the filter element 500 may be removed for replacement or cleaning.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent should be subject to the appended claims.
