Description

Locomotive helmet providing cool and clean air

The invention relates to a locomotive helmet, in particular to a full-cover locomotive helmet that can provide cool and clean air.

According to a recent report by the Taiwan Environmental Protection Agency, the concentration of fine suspended particulates (PM2.5) emitted by locomotive exhaust may be as high as 730 μg / m ³ depending on the vehicle brand and model; while waiting for traffic lights, the concentration of fine suspended particulates exposed by locomotive riders It can reach 460 μg / m ³ . Motorcyclists are exposed to fine suspended particulate concentrations significantly higher than other ethnic groups, which is quite detrimental to the health of the body, especially the lungs. In response to the above problems, motorcycle riders generally wear masks that can filter fine suspended particles, such as N95 masks to prevent the lungs from inhaling too many harmful substances. However, in addition to the uncomfortable feeling during wearing, many organic soot will also mix with fine suspended particles and stick to other parts of the face, further stimulating the facial skin. At the same time, repeated use of masks can easily accumulate bacteria and become another source of pollution.

The problem is not just breathing problems. The law mandates that helmets be worn for riding locomotive. This riding configuration increases the weight of the head (inevitably), makes the heat accumulation of the head difficult to dissipate, and absorbs the sweat of the motorcycle rider, causing the helmet to linger. Smelly smell. As we all know, the types of helmets can be divided into full-face type, faceless type, semi-faceless type and half-face type. Regardless of Which type of helmet is used, although it can greatly reduce the head injury in the event of a car accident, but in terms of type, the risk of head trauma when wearing a half-cover helmet is 2.57 times that of a full-cover helmet ( Yu et al. 2011). Due to the climatic conditions in Taiwan, especially in summer, motorcycle riders often sacrifice part of the safety, choosing face-type, semi-face-type, and half-hood helmets in exchange for a little coolness and comfort. Although many manufacturers have improved the structure of helmets in order to solve the problem of heat generation caused by helmets, the present invention discloses a more proactive method that can improve the comfort of helmets, provide cyclists with respiratory protection against fine suspended particles, and The safety of full-face helmets is no longer traded for discomfort and is a win-win creation.

At the same time, considering the hazards of fine suspended particles and the problem of the conventional helmet, there are some previous cases for finding appropriate solutions. China Utility Model No. 2052625U proposes a dustproof and cold-proof helmet device for bicyclists or pedestrians. The device is characterized by a soft, sealed cloth attached to the lower end of the helmet. When the air pollution is severe or the weather is cold, the zipper on the sealed soft cloth is pulled to death. The breathing air is purified by the filter sponge, which can effectively prevent dust and cold. Although this patent uses airtight soft cloth and filter sponge to achieve air filtration, the effect is limited. In addition, the waste heat inside the helmet cannot be effectively eliminated, and there are not many solutions to the problems encountered by motorcycle riders.

In addition, US Patent Application No. 2017/0136268 proposes a personal-powered air respirator. The powered air respirator includes a helmet, a backpack housing, a set of fans, a set of filters for input air, and a hose to direct output air to the helmet. The advantage of this case is that the dust-filtered air is blown into the helmet by a fan, and the helmet can be changed into a suitable helmet type. However, the products made according to this case are used in the car array, and it is difficult to block the air convection from below the neck of the motorcycle rider, and it is inevitable to suck in dirty air.

Finally, the new patent No. M518005 of the Republic of China proposes a dustproof helmet, which includes a cap body, an air exhaust vent and an air suction device. The cap body has an accommodating portion and an air suction port, and the air suction port is located at the lower edge of the cap body and a plurality of blocking pieces are arranged at intervals. A window is provided in front of the cap body and communicates with a wearing space, and an air outlet is provided at an edge of the cap body window and communicates with the wearing space. The air suction device is accommodated in the accommodating part and has a fan and an air guide pipe. The fan has an exhaust side communicating with the air outlet and an air suction side. The air guide pipe has opposite ends communicating with the air suction side. And air intake. The new structure design can block the dust or suspended particles and moisture in the air from entering the wearing space, and can keep the air inside the cap body clean. However, due to the poor design of the air circulation route in the cap body, the accumulated waste heat is difficult to remove.

Since the conventional technology cannot completely solve the problems encountered in the use of existing locomotive helmets, a new type of full-face locomotive helmet capable of providing cool and clean air is needed. This helmet can solve the problem of fine suspended particles when the motorcycle rider is breathing, and at the same time, it can effectively dissipate the heat accumulated on the head, further reducing the sweat generated by the motorcycle rider, causing the lingering odor of the helmet.

This paragraph extracts and compiles certain features of the invention. Other features will be revealed in subsequent paragraphs. Its purpose is to cover the spirit and scope of the scope of additional patent applications, with various modifications and similar arrangements.

In order to solve the above problems, the present invention provides a full-face locomotive helmet capable of providing cool and clean air.

The locomotive helmet disclosed in the present invention includes the aforementioned helmet body 10, a vent tube 20, a power-purifying breathing protective (PAPR-typed) air supply machine 30, and the aforementioned guide towel 40. The functions, aspects and interrelationships of these components are described below.

The helmet body 10 is a main body of a motorcycle helmet for protecting the head of a user. In terms of appearance type classification, locomotive helmets are full-covered. Since the focus of the present invention is to provide the user with clean air and take away the heat emitted by the head of the motorcycle rider in the helmet body 10, a part of the detailed structure of the helmet body 10 can be the same as any conventional technology. Not stressed. Therefore, the scope of the helmet body 10 may include, but is not limited to, an outer anti-friction protective material, an impact-absorbing cushion, a belt, and a head-side cushion. Punching pads, ear protection, protective lenses, protective lens fixtures, head cushions, neck protection, edge protection, ear cushions, etc.

Compared with the existing hat structure of the helmet, the helmet body 10 is characterized by a window opening 101, a set of openings 102, and an optional vent hole 103. In addition, there is no internal or external communication channel. . Such a design is used to effectively isolate the internal and external air circulation of the helmet body 10, thereby preventing the motorcycle rider from inhaling the air without removing fine suspended particles. Each side of the window opening 101 has a pivoting device 110 (only the pivoting device 110 on the side of the window opening 101 is shown due to the angle of view), and a protective lens 11 can be pivoted. The protective lens 11 can be pivoted to the window opening 101 and sealed. (The situation shown in FIG. 1 is that the protective lens 11 has been pivoted to the window opening 101 and closed the window opening 101, so the appearance of the two Actual coincidence). When the protective lens 11 is rotated away from the window opening 101, the air inside and outside the helmet body 10 can convect. The sleeve opening 102 is an opening for the user's head to enter the helmet body 10. In practice, part of the space of the socket 102 may be occupied by a cushion pad 104. The socket 102 is provided with a first connecting device 105. The first connecting device 105 is a tool that comes into close contact with the guide towel 40. Its appearance and detailed functions will be described in the following text.

As mentioned above, the ventilation holes 103 of the helmet body 10 are selectively opened. If the safety helmet body 10 is not provided with a vent hole 103, it can also be opened in the protective lens 11. For convenience of description, the position of the vent hole 103 is referred to as an opening position. In this embodiment, as shown in FIG. 1, the opening position is behind the top of the helmet body 10 (relative to the user's viewing direction). According to the present invention, in another embodiment, the opening position may be near the user's chin (as shown by the oblique line in FIG. 5) in the helmet body 10; in another embodiment, the opening position is also It may be one of the two sides of the protective lens 11 (as shown by the oblique line in FIG. 6). Different opening positions will produce different air circulation effects within the helmet body 10, and the description of the internal air circulation will be disclosed below.

One end of the ventilation tube 20 is connected to the ventilation hole 103, and the other end is connected to the power net air breathing protective air supply device 30. The type and material of the vent tube 20 are not limited, and it is preferably a hose, such as a PVC (PolyVinyl Chloride) hose or an EVA (Ethylene Vinyl Acetate) hose, so that the user can flexibly turn his head without limitation. The power-purifying respiratory protective air supply device 30 is an air supply device for a power-filtered respirator (Powered Air Purifying Respirator, PAPR). Powered filter respirator is a kind of high-efficiency particulate filter respirator. The blower and the battery are usually worn on the wearer's belt or the back of the hood. Bring the air containing pollutants to high-efficiency filter media to filter out fine suspended particles. If used with an adsorption tank, it can also remove some gaseous pollutants at the same time. In general, the power-purifying breathing protective air supply device 30 may include a host, a high-performance filter, a belt, a flow indicator, and the like, and the present invention is not limited to the detailed structure thereof. However, in order to be able to effectively provide power, the powered net gas breathing protective air supply device 30 may be connected with a portable secondary battery pack or a locomotive battery (not shown) as a source of power. The function of the power-purifying respiratory protective air supply device 30 in the locomotive safety helmet of the present invention is to filter fine suspended particles from the external air, and then transmit the fine suspension particles to the inside of the safety helmet body 10 through the ventilation pipe 20. The air supply rate of the power net clean breathing protective air supply machine 30 varies from one manufacturer to another. In order to effectively provide cool and clean air without causing excessive accumulation of carbon dioxide (CO ₂ ) in the helmet body 10, it has been confirmed by experiments that the air supply rate of the powered net air breathing protective air supply device 30 is preferably between 60 liters / minute to 100 liters / minute.

The guide towel 40 (the plane of which is shown in the lower part of FIG. 2) is made of air-impermeable material, and has a second connecting device 401 on the upper end, which can be detachably connected to the first connecting device 105. The purpose of the connection is to allow the user to put on the guide towel 40 after putting on the helmet body 10 so as to prevent the fixed guide towel from being rolled into the helmet body 10 by the head. When the first connecting device 105 and the second connecting device 401 are connected, the flow guide towel 40 can surround the neck of a user wearing the motorcycle helmet by more than one circle, as shown in FIG. 4 Shown in the upper section of the use state. Since there is a constant flow of clean air from the helmet body 10 to form a stable airflow, in order to guide the airflow and prevent the inflow of dirty air from the outside of the helmet body 10, the guide towel 40 is used to guide the air inside the helmet body 10 toward it Discharge at the lower end, while isolating the convection of outside air.

In this embodiment, the plane of the guide towel 40 is a rectangular design, and the second connecting device 401 at the upper end thereof is a devil felt having a hook structure or a devil felt having a ring structure. Therefore, the first connecting device 105 It may be a devil felt having a ring structure or a devil felt having a hook structure corresponding to the second connection device 401. That is, if the second connecting device 401 is a devil felt having a ring structure, the first connecting device 105 has a devil felt having a hook structure; if the second connecting device 401 is a devil felt having a hook structure, the first The connection device 105 has a devil felt having a ring structure. Since the first connecting device 105 is at the lower edge of the helmet body 10, the devil felt structure can effectively connect the guide towel 40 to the helmet body 10 and prevent outside air from flowing into the helmet body 10.

In this embodiment, the material of the deflector 40 can be a polypropylene (PP, Polypropylene) synthetic fiber, for example, a commercially available cover towel (Neckerchief) is used; the material of the deflector 40 can also be polyester. For example, a commercially available Scarf is used as the fiber; the material of the deflector 40 can be a melt-blown polypropylene, such as a middle layer filter material in a mask structure. In addition to petrochemicals, the guide towel 40 can also be made of natural textiles or blends. For example, the material of the guide towel 40 may be a functional fabric (soft shell material) composed of an elastic cloth and a plain weave. Of course, if the air tightness is not good, a waterproof film, such as a polyethylene (PE, polyethylene) film, may be coated on the outside of the guide towel 40. It should be noted that the length of the guide towel 40, as shown by H in the lower part of FIG. 2, must be a certain length. The reason is that the outside wind speed will blow up the guide towel 40, making the guide towel 40 unable to effectively block the ride. Airflow during the car. Observed from experimental data, the length design of the guide towel 40 needs to be at least 28 cm or more in order to effectively block the air flow during cycling. That is, the length H from the upper end to the lower end is not shorter than 28 cm.

Go back to Figure 1. When the user puts on the hard hat body 10, installs the guide towel 40, and starts the power-purifying breathing protective air-supplying machine 30, the external air passes through an air inlet 301 of the power-purifying breathing protective air-supplying machine 30. After entering, the pollutants and fine suspended particles are removed by the power-purifying respiratory protective air supply device 30, and then flow through the ventilation tube 20 into the upper part of the helmet body 10 in the direction of the virtual arrow. After the heat of the user's head is taken away, it flows along the space between the protective lens 11 and the user's face, and flows below the helmet body 10. Then, this air flows out of the helmet body 10 and is guided downward by the guide towel 40 until it is discharged to the outside of the guide towel 40. That is, after the user puts on the motorcycle helmet, the filtered air flows into the helmet body 10 and passes through the user's head, and the heat is transmitted to the outside air through the air guide towel 40. Achieved the purpose of providing cool and clean air for motorcycle riders. When cold, the filtered air can also be guided through the ducts to allow it to flow through the hot surfaces of the engine to increase the temperature.

According to the spirit of the present invention, there are other options for the position of the opening, and different aspects are described below. Please refer to FIG. 5, which illustrates the position of the vent hole 103 and the airflow direction in another embodiment. The left side is a side view of the helmet body 10, and the right side is a top view of the helmet body 10. Since the opening position is near the helmet body 10 near the user's chin, the filtered clean and cool air will enter the side of the helmet body 10 along the ventilation tube 20. After entering the helmet body 10, the air will move along the side of the human face toward the upper part of the helmet body 10 (the position of the back of the brain), taking away the heat from the user's head. Then, as in the previous embodiment, air flows along the space between the protective lens 11 and the user's face, and flows below the helmet body 10. Finally, the air flows out of the helmet body 10 and is guided downward by the guide towel 40 until it is discharged to the outside of the guide towel 40. Compared with the previous embodiment, this design needs to destroy the body structure of the helmet, and is not suitable for the modification of the existing hat body. .

Please refer to FIG. 6 again, which illustrates the position of the vent hole 103 and the airflow direction in another embodiment. The left side is a side view of the helmet body 10, and the right side is a top view of the helmet body 10. Due to openings The position is on one of the two sides of the protective lens 11. The filtered clean and cool air will enter the side of the safety helmet body 10 along the ventilation tube 20. After entering the helmet body 10, air will not reach the upper part of the helmet body 10, and the heat of the user's head will be taken away. Conversely, the air will flow along the eyes and cheeks to the space between the protective lens 11 and the user's face, and turn in the direction to flow below the helmet body 10. Finally, the air flows out of the helmet body 10 and is guided downward by the guide towel 40 until it is discharged to the outside of the guide towel 40. Compared with the previous embodiment, the airflow of this design has a narrower flow range, and the heat of the head is easier to accumulate, which is suitable for riding a motorcycle in winter.

Due to the perimeter of the human body, it is increasing from below the neck. If the length H of the guide towel 40 is designed to be long, the guide towel 40 of a fixed width may not be able to effectively reach a circle around the neck of the user wearing the motorcycle helmet Above ". Therefore, in another embodiment, the design width of the guide towel 40 may be gradually increased from the upper end to the lower end, as shown in FIG. 3. In order to ensure that both sides of the guide towel 40 can be effectively closed, fixing devices 402 can be added on both sides of the guide towel 40 to fix the guide towel 401 to ensure that it can “circle around the neck of a user wearing a motorcycle helmet” (As shown in the lower part of Figure 4). In practice, the fixing device 402 may be a set of zippers, a plurality of snaps, or a set of devil felt.

Although the present invention has been disclosed as above in the embodiments, it is not intended to limit the present invention. Any person with ordinary knowledge in the technical field can make some modifications and retouching without departing from the spirit and scope of the present invention. The protection scope of the present invention shall be determined by the scope of the attached patent application.
