Description

  The present invention relates to a fan-equipped mask that is movable by a solar cell.

  Conventionally, various types of masks have been used for hay fever, medical workers, clean room workers, hazardous dust workers, etc., and the part that contacts the nostril of the human body is contained in the air from the outside Cotton gauze, synthetic fiber nonwoven fabric and the like containing a component that removes harmful components are used.

  As a form of the contact portion, a flat sheet, a pleat or the like added thereto, and a space portion between the mouth and the mask were devised to facilitate conversation and prevent breathing. A shape is known.

  Breathing may become difficult due to the contact of the mask with the nostril of the human body, especially for workers involved in hazardous dust construction, it is necessary to increase the sealing of the mask to prevent the invasion of dust, making breathing more difficult become.

  To increase the sealing performance of the mask is to provide a filter function that physically or chemically captures fine powder such as pollen that harms the general public from the natural world or artificially radioactive dust in a nuclear power plant. Meaning that the ventilation resistance tends to increase.

  For this reason, it becomes difficult for a general person or worker wearing a mask having a filter function with high ventilation resistance to breathe sufficiently only with his / her lungs, and the general person's behavior and the workability of the worker are reduced. Come out.

  In order to solve these problems, a proposal related to a breathing interlock type blower mask system with a fan has been made (Japanese Patent No. 3726886, Japanese Patent Application Laid-Open No. 2008-194092).

  All of these methods are intended for hazardous dust construction workers and focus on the correlation between the breathing rate for a certain period and the power consumption of the blower drive motor. You are using battery power.

  In addition, these methods are intended for hazardous dust workers, but it is necessary to provide a portable power source when considering a portable mask that can be used by the general public. It becomes.

  The present invention has a system for storing light energy applied from indoor light such as sunlight and fluorescent lamps in a secondary battery, and provides a mask with a fan that can be operated by electric energy obtained from this system. Let it be an issue.

  In order to solve the above problems, the fan-equipped mask that operates on the solar cell of the present invention forms a solar cell on the mask surface for absorbing light energy necessary for operating the fan, and at the same time uses the light energy as electric energy. A secondary battery such as a lithium ion battery for storing electricity is formed on the mask surface.

  A silicon-based solar cell can be used as the solar cell, but a dye-sensitized solar cell or an organic thin-film solar cell formed on a flexible plastic surface can also be used on the mask surface. It is.

  As a light energy source, a solar cell that absorbs not only sunlight but also room light is used, and it is necessary to effectively utilize the mask surface in order to enlarge the area as much as possible.

  For example, when a lithium ion battery or a lithium ion polymer battery having excellent energy efficiency is used as the secondary battery for storing electric energy, the mask can be compactly attached.

  Any type of fan can be used on the mask surface as long as it has the smallest possible shape.

  As described above, according to the present invention, it is possible to provide a portable mask while miniaturizing a mask with a fan by attaching a solar cell using light energy as an energy source to the mask body.

It is an oblique view of the fan-equipped mask according to the present invention. It is the II-II sectional view taken on the line of the mask shown in FIG.

  Embodiments of the present invention will be described in detail with reference to the drawings.

  In addition, the form described below is only one aspect | mode of embodiment of this invention, and this invention is not limited to these.

  In the fan-equipped mask 1 that is operated by a solar cell, through holes 3 for taking in outside air are formed in a lattice shape in the upper center of the face piece 2. The through-hole 3 is formed at a location located near the nasal cavity of the human body when masked.

  It is necessary to select the most suitable member for the above-mentioned face body 2 according to each purpose such as for hay fever, for medical workers, for clean room workers, for dust workers, etc. For example, by using a laminated nonwoven fabric composed of a thermoplastic synthetic fiber nonwoven fabric for the outer layer portion and a nonwoven fabric containing regenerated cellulose fibers for the inner layer portion, it has moderate moisture retention and breathability and a three-dimensional shape. The face piece 2 having excellent holding performance can be produced.

  A hollow intake frame body 4 is attached to the face body 2 so as to cover the through hole 3 outside the through hole 3.

  The intake frame 4 is provided with a filter 5 that blocks the outside from the inside of the face body 2 and removes harmful substances from the outside.

  It is necessary to select an optimal member for removing harmful components from the outside according to the purpose of hay fever, for medical workers, for clean room workers, for dust workers, etc. Yes, for example, for medical professionals, it is possible to use a single layer or multiple layers of aliphatic polyester nonwoven fabrics.

  These aliphatic polyester layers are produced by appropriately selecting combinations of nonwoven fabrics having different basis weights, fiber diameters, and fiber densities.

  A fan 6 is provided between the filter 5 and the through hole 3 inside the intake frame 4 for sucking air obtained by filtering outside air through the filter 5.

  The fan 6 is attached to the filter 5 integrally with a motor 8 and is rotatable with the solar cell 7 as an energy source and the motor 8 as a power source. The motor 8 is embedded and fixed in the filter 5.

  Since the fan 6 is provided between the filter 5 and the through hole 3, safety can be ensured without the fan 6 coming into contact with the nasal cavity of the human body when masked.

  A solar cell 7 that absorbs as much light energy as possible is formed on the surface of the face piece 2.

  This solar cell has a structure capable of efficiently absorbing not only solar energy but also room light, for example, light energy such as a fluorescent lamp.

  As a specific solar cell 7, a crystalline silicon-based or thin-film silicon-based solar cell or a dye-sensitized or organic thin-film-based solar cell can be used, but the former two silicon-based solar cells are dark brown. Since the two organic solar cells are colorful, they can be used properly according to the purpose.

  When the mask material is flexible, it is possible to improve the light energy absorption efficiency by forming it on the entire surface of the face piece 2 by using a flexible organic solar cell. It becomes.

  The solar cell 7 above the intake frame 4 is provided with a secondary battery 9 for storing electric energy of the solar cell 7.

  As the secondary battery 9 for storing electrical energy, a lithium ion battery or a lithium ion polymer battery can be used in view of performance such as energy density and conversion efficiency.

  The secondary battery 9 is provided so that the motor 8 can be moved even when the solar battery 7 cannot absorb light energy. Therefore, the motor 8 can operate even when it is raining or cloudy.

  Furthermore, a temperature sensor 10 is attached to the face body 2 on the back side of the secondary battery 9 to sense the human body when masked.

  The temperature sensor 10 is connected and wired to the motor 8, and when the human body sense is sensed, the motor 8 is moved and the fan 6 connected and wired to the motor 8 is activated so that the outside air can be transferred to the face 2. It is the structure which can be sucked inside.

  Therefore, when the mask is removed, the temperature sensor 1 does not sense the human body, so the movement of the motor 8 is stopped. This temperature sensor 10 is provided as a switch of the motor 8.

  As described above, in the above-described embodiment, the fan-equipped mask that operates on a solar cell has been described as an example. However, in the present invention, an optimal member can be selected as the mask body 2 according to the purpose of use. Necessary and the members are different for hay fever and dust workers, but in any case, it is necessary to select an optimal solar cell corresponding to the member of the face piece 2.

  Moreover, by attaching a solar cell to the face body 2 as described above, the power supply and the fan function can be integrated to reduce the size and provide a portable fan-equipped mask.

  In the above embodiment, the exhaust of the human body breathing in the mask is not described, but since it is a portable mask, the exhaust can be performed from the gap between the mask and the face of the human body.

  If necessary, this mask can be provided with an exhaust valve. This exhaust valve is preferably provided on the mask body 2 in front of the mouth of the human body when masked.

  This exhaust valve is provided with an exhaust hole formed in the face piece 2 so as to always close the exhaust hole and move outward.

  A filter for closing the exhaust hole is provided outside the exhaust valve to prevent outside air from directly entering the mask when the exhaust valve moves outward.

  By providing such an exhaust valve, the reverse addition to the fan 6 due to the exhaust of the human body can be prevented during breathing, and smooth intake of the fan 6 can be ensured.

Reference numeral 1 denotes a solar cell-operated mask 2, a face plate 3, a through hole 4, a suction frame 5, a filter 6, a fan 7, a solar cell 8, a motor 9, a secondary battery 10, a temperature sensor
