  As shown in FIG. 2, the wearing body 1 is a blouson type with a short sleeve and a standing collar, and the material is manufactured with a transparent vinyl sheet. The standing collar portion functions as the air discharge portion 11 and is formed so as to cover the user's neck without contact. For this reason, the standing collar portion can generate a flow of air to be released from the lower side to the upper side of the user's face.

  Further, in the wearing body 1, a unit part mounting hole 12 that is substantially the same shape as the outer peripheral part of the unit part 2 and slightly smaller in size is provided at a position where the unit part 2 is attached. An elastic band is provided on the inner edge, and the unit part 2 is fixed to the wearing body 1 by the elastic force of the elastic band. Moreover, the end part of the short sleeve part 13 of the wearable body 1 and the skirt part 14 are provided with a rubber string, and it is comprised so that air may not leak by the elastic force of the rubber band concerned.

  As shown in FIG. 3, the unit unit 2 includes a fan main body 21, a power source 22 that supplies driving power to the fan main body 21, a filter, etc., and adjusting means 23 that adjusts the amount of a substance contained in the outside air, a finger guard, etc. Protective member, an air intake part 24 having an opening for taking in outside air, and an air delivery part 25 having an opening for sending out air that has been taken in and cleaned to the inside of the wearing body 1. The

The unit unit 2 supplies driving power from the power source 22 to rotate the fan main body 21, thereby taking in outside air from the air intake unit 24 and supplying outside air purified by the adjusting means 23 from the air delivery unit 25. 1 is configured to be sent inside.
Moreover, two flange parts 27 and 28 are formed in the outer peripheral part 26 for making it closely_contact | adhere to the edge of the unit part attachment hole 12 of the wearing body 1 on the upper side and the lower side of the outer peripheral part 26 as needed. Note that the air intake unit 24 may be opened and closed, or may be detachable from the unit unit 2 so that the adjustment means such as a filter can be easily replaced.

Next, a method for wearing the portable air cleaning device 100 will be described.
The unit part 2 is hung from the neck to the chest, the wearing body 1 is worn, and the outer peripheral part 26 of the unit part 2 is inserted into the unit part mounting hole 12 and fixed. The unit part 2 may be fixed directly to the unit part mounting hole 12 of the wearing body 1 without hanging from the neck to the chest.

  Specifically, when the two flange portions 27 and 28 are formed on the upper side and the lower side of the outer peripheral portion 26, the edge of the unit portion mounting hole 12 provided with a rubber cord is connected to the flange portion on the upper side of the unit portion 2. 27, the unit portion 2 is securely fixed to the wearable body 1 by dropping an edge between the upper flange portion 27 and the lower flange portion 28.

Next, the operation of the portable air cleaning device 100 will be described.
When the switch (not shown) of the unit unit 2 is turned on, driving power is supplied from the power source 22 and the fan main body 21 rotates. As shown in FIG. 4, the outside air OA 41 containing fine particles and the like from the air intake unit 24 Air IA41, IA42, and IA43 taken into the unit portion 2 and cleaned by removing fine particles by the adjusting means 23 is sent from the air sending portion 25 into the wearable body 1.

  Since the air IA41, IA42, and IA43 thus taken in are configured such that the end portion and the skirt portion 14 of the short sleeve portion 13 of the wearable body 1 do not leak air as described above, It flows toward the upper side and is discharged from the upper end portion of the standing collar functioning as the air discharge portion 11 to the outside of the wearing body 1.

  In particular, the cleaned air IA41, IA42, IA43 emitted from the user's face part can be vigorously directed upwards to cover the nose, and the air flow can be generated substantially parallel to the face. For this reason, the user can breathe only the cleaned air IA41, IA42, IA43. In addition, an air flow is always generated from the lower side to the upper side of the user's face, and a so-called air curtain is formed, so that the outside air can be prevented from flowing in.

The unit 2 may be provided with an air volume adjusting means that can adjust the air volume of the outside air sent from the air sending section 25 according to weather conditions.
For example, if the wind is blowing strongly and the flow of air that always flows from the lower part to the upper part of the face of the user is disturbed, the air flow from the lower part to the upper part can be increased by increasing the air volume. The flow can be maintained. Further, for example, when the wind is hardly blowing, it is possible to cope with the air volume being weakened without increasing the air volume more than necessary.

  In addition, when the adjustment means 23 such as a filter purifies a large amount of outside air, the adjustment function is reduced (particularly when the pressure loss is increased by the adsorbed fine particles and the amount of air to be sent is reduced), What is necessary is just to open the air intake part 24 and replace | exchange for the new adjustment means 23. FIG.

  Further, in the first embodiment, the unit body 2 is illustrated in which the fan main body 21, the power source 22, and the adjusting means 23 are integrated. However, the fan main body 21, the power source 22, and the adjusting means 23 are individually provided. May be.

The fan body 21 that takes outside air into the wearing body 1 through the adjusting means 23 and sends the taken-in air into the wearing body 1 from the air delivery section 25, and a power source 22 that supplies driving power to the fan body 21 With. And the air discharge | release part 11 produces the flow of the air to discharge | release substantially parallel to a face, and can provide the portable air purifier which does not have the feeling of pressure at the time of use and does not flow in external air.
In addition, the appearance, especially around the neck, is covered with a standing collar often seen in winter, so there is no sense of incongruity, and there is nothing that touches the nose or mouth, so there is no feeling of pressure like a mask.

(Modification 1)
In the wearable body 1 of the portable air purifying device 100 according to the first embodiment of the present invention, the standing collar portion is formed so as to cover the user's neck in a non-contact manner, and functions as the air discharge portion 11. However, depending on weather conditions such as strong winds and storms, it may be difficult to generate a flow of released air substantially parallel to the face.

  For this reason, in the first modification, as shown in the schematic front view of FIG. 5A, the air guiding portion formed so as to cover the lower half of the face including the user's nose and mouth portions in a non-contact manner. 15, the flow of the air taken in is surely generated substantially in parallel with the face, and discharged from the air discharge portion 11 a to the outside of the wearing body 1 a. In addition, the structure regarding the wearable body 1a and the unit part 2 other than the wearable body 1a having the air guidance | induction part 15 is the same as 1st Embodiment.

  Further, as shown in the schematic plan view of FIG. 5B, the upper end of the air guiding portion 15 is made of a material having a very low density, such as a sponge, between the face and the back of the head and is used by the user. An air leakage prevention means 3 is provided for preventing air leakage from a portion other than a portion near the nose.

  The air leakage prevention means 3 eliminates a gap between the user's face or back of the head and the air guiding portion 15. For this reason, in the modified example, the air flow is generated only in the upper part of the user's nose where the air leakage prevention means 3 is not provided. As a result, the cleaned air can be more efficiently flowed near the user's nose.

Next, the operation of Modification 1 will be described.
When the switch (not shown) of the unit unit 2 is turned on, driving power is supplied from the power source 22 and the fan main body 21 rotates. As shown in FIG. 6, the outside air OA 61 containing particulates or the like from the air intake unit 24 is Air IA61, IA62, and IA63 taken into the unit part 2 and cleaned by removing fine particles by the adjusting means 23 is sent from the air sending part 25 into the wearable body 1a.

  The air IA61, IA62, and IA63 taken in this way flows toward the upper side of the wearing body 1a because the air leakage preventing means is formed at the end portion and the hem portion 14 of the short sleeve portion 13 of the wearing body 1a. It passes through the air guiding portion 15 and is discharged to the outside of the wearing body 1a from the upper end portion of the standing collar that functions as the air discharge portion 11a.

  Specifically, the amount of air that is taken in and cleaned is at least about three times that of respiration, and air does not leak outside of the air discharge part 11, so the pressure near the nose is positive even during respiration. There is no outside air flowing back from the air discharge part 11.

  In particular, the flow of the purified air IA61, IA62, and IA63 when passing through the air guiding unit 15 is surely generated substantially parallel to the user's face regardless of weather conditions such as strong winds and storms. it can. For this reason, the user can breathe only the cleaned air IA61, IA62, IA63. Moreover, since the part of a user's face is covered with the air guidance | induction part 15 non-contacting, it can prevent that external air flows in.

  Further, since the air leakage prevention means 3 restricts the flow area of the cleaned air IA61, IA62, IA63, for example, the cleaned air IA61, IA62, IA63 is irrelevant to the breathing of the user such as the back of the head. Therefore, the purified air can be more efficiently flowed in the vicinity of the user's nose and contribute to the user's breathing.

  In addition, since the entire inside of the wearable body 1 is positive pressure, the clothing swells and also has a buffer function when breathing, so even if the breathing volume momentarily exceeds the amount of air taken in, the buffer effect makes it near the nose The pressure is kept at a positive pressure. Therefore, the user can breathe only the purified air.

  As described above, according to the first modification, by having the air guiding portion 15 formed so as to cover the lower half of the face including the user's nose and mouth portions in a non-contact manner, strong winds, storms, etc. Regardless of the weather conditions, a clean air flow can be reliably generated substantially parallel to the user's face. In addition, the appearance, especially around the neck, is covered with a standing collar often seen in winter, so there is no sense of incongruity, and there is nothing that touches the nose or mouth, so there is no feeling of pressure like a mask.

(Modification 2)
The adjustment means 23 of the portable air cleaning device 100 according to the first embodiment of the present invention is a member that reduces and adjusts the amount of substances contained in the outside air such as a filter, but instead of the filter, It may be a sponge containing water having many through holes.

  That is, when the dried outside air taken in from the air taking-in part 24 passes through the hole of the sponge containing water, the air is humidified, and the humidified air can be breathed as breathing.

(Modification 3)
The adjusting means 23 of the portable air cleaning device 100 according to the first embodiment of the present invention is a member that reduces and adjusts the amount of substances contained in the outside air such as a filter. However, activated carbon is mainly used instead of the filter. It may be a carbon monoxide adsorber as a component.
