As described above, means with various configurations have been provided, but none are fully satisfactory.
In the present invention, harmful particles and gases in a fire, etc., or suspended particulate matters such as dust, pollen and viruses contained in the outside air, or gaseous matters such as sulfur dioxide and nitrogen monoxide contained in the outside air are removed. Thus, it is an object of the present invention to provide an effective protective device for preventing inhalation or exposure to the face.

  In the present invention, in order to achieve the above-mentioned object, each part of the visible hood in which an opening having a closing mechanism is formed in the lower part is fixedly supported by a cylindrical spacer that supports the head to surround the visible hood. For the hood, we propose a protective device with a contaminant removal filter at the corresponding part of the mouth of the user.

  Further, in the present invention, each part of the visible hood having an opening having a closing mechanism in the lower part is fixedly supported by a cylindrical spacer that supports the head around the head, and the visible hood has a user's mouth. The protective equipment which provided the contaminant removal filter in the corresponding part of the part, and fixed and supported the contaminant removal filter to the cylindrical spacer is proposed.

  Further, the present invention proposes a protector having a configuration in which, in the above-described configuration, each portion of the visible hood is fixed by providing a gap through a plurality of pin-like bodies protruding outward from the cylindrical spacer.

  Moreover, in this invention, the said structure WHEREIN: The cylindrical spacer proposes the protector comprised with the heat insulation raw material.

  The present invention also proposes a protective device having a visible hood provided with an exhaust part with a check valve in the above-described configuration.

  Further, according to the present invention, in the above configuration, an air conducting member is provided around the contaminant removal filter so as to cover the outer periphery of the user's mouth with a space therebetween and to closely contact the periphery of the filter. We propose a protective device with an exhaust with a stop valve.

  The present invention also proposes a protector provided with an electric fan for the contaminant removal filter in the above configuration.

  According to the present invention, in the above configuration, the pollutant removal filter proposes a protector comprising an upstream dust removal filter and a downstream gas removal filter.

  Further, the present invention proposes a protector having a heating means on the upstream side and a cooling means on the downstream side between the dust removal filter and the gas removal filter in the above configuration.

  According to the present invention, in the above configuration, an air path to the mouth of the user and an air path to the space in the cylindrical spacer are formed on the downstream side of the contaminant removal filter. Propose protective equipment with outlet.

  In the protector according to the present invention, the visible hood is stably supported because each part of the visible hood having an opening having a closing mechanism at the lower part is fixed and supported by a cylindrical spacer that surrounds and supports the head. The function of the visible hood can be exhibited well.

  The visible hood can be handled and stored easily by using a flexible material. Normally, when such a flexible material is used, the visible hood contracts and expands with the respiratory activity of the user, and this deformation causes a problem that unpleasant noise occurs. By supporting the hood as described above, deformation of the visible hood is prevented, and such a problem does not occur.

  In the present invention, the contaminant removal filter provided in the visible hood can be supported only by the visible hood if the user is very lightweight and is configured to take in clean air in a self-breathing manner. If the contaminant removal filter is fixed to the cylindrical spacer and supported, even if it becomes relatively heavy by providing elements such as an electric fan, heating means, cooling means, etc. to improve the contaminant removal performance, It can be supported stably.

  In addition, the cylindrical spacer forms a stable gap between the visible hood and the user's head, and the cylindrical spacer itself is also formed with a hollow space. By using a material having high heat resistance and heat insulation performance for the visible hood and the cylindrical spacer, the user's head can be effectively protected in a fire or the like.

  In particular, when each portion of the visible hood is configured to be fixed with a plurality of pin-like bodies protruding outward from the cylindrical spacer, the heat insulation performance can be further enhanced.

  Further, in the present invention, an air conducting member is provided around the contaminant removal filter so as to cover the outer periphery of the user's mouth with a space therebetween and to closely contact the circumference, and the air conducting member is provided with a check valve exhaust portion. By providing this, the user's self-breathing can be performed efficiently.

  In the present invention, the contaminant removal performance is high by providing the electric fan in the contaminant removal filter. However, even when a filter with a high pressure loss is used, the user can easily breathe.

  For example, the contaminant removal filter is composed of an upstream dust removal filter and a downstream gas removal filter, and a heating means is provided on the upstream side between the dust removal filter and the gas removal filter and the downstream side is cooled. If the structure is provided, dust, pollen particles, viruses, virus droplets, etc. contained in the air are killed or inactivated by contact with the heating means installed in the mask, thus removing contaminants. Since the performance becomes very high and the air that has become hot is cooled by the cooling means, it does not adversely affect the user.

  In addition to the function of supporting the visible hood and the contaminant removal filter, the cylindrical spacer branches off from the air path to the user's mouth on the downstream side of the contaminant removal filter. An air path that flows out from the air outlet through the space can be configured.

Next, an embodiment of the present invention will be described with reference to FIGS.
In the figure, reference numeral 1 denotes a visible hood, 2 denotes a cylindrical spacer, 3 denotes a space portion thereof, and 4 denotes a contaminant removal filter. In the figure, reference numeral 5 denotes an opening in the lower portion of the hood 1, and the opening 5 is provided with a closing mechanism 6 as shown in FIG.

  First, FIGS. 1 to 6 show a self-breathing type hood suction-type protective device, which includes a visible hood 1 and a contaminant removal filter 4 that wraps the entire head. Contaminants in the outside air are removed by the filter 4 installed at the front part of the hood 1, and clean air is supplied to the self-respirator by the user's self-breathing.

  Dust and gaseous substances contained in the air supplied to the hood 1 are removed, for example, by a dust removal filter 7 and a gas removal filter 8 as shown in FIG. 10 or FIG. Brought about.

  When using this protective equipment, contamination in the hood 1 by contaminated outside air must be prevented. Therefore, in order to prevent the intrusion of outside air that does not pass through the filter 4 in the present protector, the following device is provided for the opening 5 at the neck portion.

  That is, the opening 5 corresponding to the user's neck circumference is easily tightened with a string constituting the closing mechanism 6, Velcro (registered trademark) or the like so that the inside of the hood 1 is sealed. It has a structure.

  On the other hand, when a flexible material is used for the hood 1, the hood 1 contracts and expands with respiratory activity. This deformation of the hood 1 causes unpleasant noise and causes a problem. In the protective equipment of the present invention, the hood 1 is fixed and supported by using the cylindrical spacer 2 that is in close contact with the head. Deformation can be prevented. That is, the cylindrical spacer 2 has a hollow structure using a heat insulating material, and is further connected by a pin-like body 9 in order to reduce the contact area with the hood 1. Thereby, between the hood 1 and a user's head, the heat insulation air layer which prevents conduction of the heat | fever in external air is formed.

Next, FIGS. 5 to 7 show a self-breathing type and a direct suction type protective device.
In this protective device, in order to improve the efficiency of removing pollutants from the outside air by self-breathing, as a breathing aid for the downstream side of the pollutant removal filter 4 tightly contacting the mouth of the user, that is, the respiratory organ. An air conduction member 10 is provided.

  This protective device has the same characteristics as the self-breathing type in-hood suction type described above, and has a mechanism in which dust and gaseous substances contained in the air supplied to the hood 1 are removed by the contaminant removal filter 4. It is what you have. The air conducting member 10 can efficiently guide clean air to the user's respiratory organ.

Next, FIG. 8 to FIG. 14 show an example of a mechanical hood diffusion type protective device using the electric fan 11.
This protective equipment generally has all of the following functions.
1. 1. A function that prevents exposure of harmful substances such as heated air, radiant heat, and viruses by covering the entire head and face where human centers and sensory organs are concentrated with a transparent hood. 2. A function that removes suspended particulate matter such as dust, pollen and viruses contained in the outside air and supplies clean air to the respiratory organs. Function to remove harmful gaseous substances such as sulfur dioxide and nitric oxide contained in the outside air and supply clean air to the respiratory system

  That is, in this protector, outside air is supplied into the hood 1 by the electric fan 11. At this time, the suspended particulate matter such as dust in the outside air is removed by the dust removal filter 7 constituting the contaminant removal filter 4, and the gaseous matter is removed by the gas removal provided on the downstream side of the dust removal filter 7. It is removed by the filter 8. Thus, the clean air filtered by the two filters is supplied into the hood 1 by the electric fan 11.

  As a problem common to this type of protective equipment and all types of protective equipment described above and later, indoor air is heated to a high temperature in the event of a fire, and the radiant heat from the heated air and the combustion surface is This was a problem to be solved when using protective equipment for evacuation such as fire. In the protector of the present invention, the visible hood 1 is made of a visible light transmissive material that facilitates evacuation. However, for radiant heat (infrared rays), metal coating may be applied to the heat-resistant film in order to prevent penetration into the hood 1.

  On the other hand, in other usage methods, when microbial particles such as viruses enter the hood 1, the virus adheres to the mucous membrane of the eyeball, causing an accident. Therefore, in the protector using the electric fan 11, the supply air may be branched by a bypass duct having an appropriate configuration and partly supplied into the hood 1. For example, in the above-described example, the cylindrical spacer 2 functions as a bypass duct.

  Therefore, when the electric fan 11 is used, the air in the hood 1 is always clean and kept at a positive pressure. Thereby, the person who uses the protective equipment of this invention is not exposed to a virus or harmful gas. Furthermore, as shown in FIG. 17, the protective device may be provided with an exhaust portion 13 with a check valve 12 in the hood 1 in order to ensure a positive pressure in the hood 1 and prevent a backflow of contaminants in the outside air.

  As described above, when this protective device is used for fire evacuation, in order to protect the head and face from the heat at the time of fire, heat insulation such as the cylindrical spacer 2 as described above between the hood 1 and the head and face. It is preferable to use this spacer. The spacer used in this way is made of a heat-resistant and stretchable material, and also has a function as a fixture and a close contact between the hood 1, the contaminant removal filter 4 and the head. Thus, the user of the protective device of the present invention can always take clean air into the respiratory system, and can avoid damage from exposure to biological particles such as viruses and gaseous substances via the skin and eyeballs.

Next, FIGS. 15 to 16 show an example of a mechanical direct suction type protective device using the electric fan 11.
In this protective equipment, the electric fan 1 supplies clean air that has passed through the contaminant removal filter 4 directly to the vicinity of the user's respiratory organ.

  Dust, pollen particles, viruses, virus splashes, and the like contained in the introduced air are first killed or inactivated by contacting heating means 14 such as a heater provided in the contaminant removal filter 4. The heating means 14 may be provided with a means for increasing the contact area with the target air to be heated, for example, by providing a configuration in which the air flow path is narrowed in a venturi shape. The air thus heated by the heating means 14 and inactivated dust, pollen particles, viruses, virus splashes and the like is cooled in the cooling means 15 such as a heat exchange radiator and cooled to a temperature at which there is no problem. It is safe because it is led to the user's respiratory system.

  In addition, the hood 1, the cylindrical spacer 2, and the pollutant removal filter 4 used for each method and each mold described above can be appropriately combined to constitute a protective device.
