Description

  The present invention relates to an air purification device.

  Various germs such as viruses exist in the atmosphere, and when such viruses are aspirated, there is a possibility that they will become infected with the virus. Therefore, as countermeasures against viruses and the like, generally, countermeasures such as wearing a mask to prevent the suction of viruses and the like have been taken.

  However, even if the mask is worn, it is difficult to completely seal the space between the mask and the face surface, so that it is difficult to allow all air sucked by a person to breathe through the mask. Moreover, since fine viruses and the like pass through the mask, the effect of preventing the suction of viruses and the like by the mask is limited.

In recent years, the bactericidal action etc. which chlorine dioxide gas has attracted attention, and the technique for purifying the air which a person breathes using chlorine dioxide gas is developed (for example, patent documents 1).
Patent Document 1 discloses an air purification device in which a chlorine dioxide powder is enclosed in a bag and the package is contained in a container. Patent Document 1 also discloses an air purification device that can be carried by attaching a strap to the upper end of a container and hanging it around the neck.

Utility Model Registration No. 3154094 JP 2010-17520 A

Even in the air purification device of Patent Document 1, air can be purified if chlorine dioxide discharged from the container comes into contact with air.
However, in the case of the air purification device of Patent Document 1, since there is no function of forcibly discharging chlorine dioxide from the container, contact with chlorine dioxide is limited to the air in the vicinity of the container.

  If an apparatus as shown in Patent Document 2 is used, there is a possibility that chlorine dioxide can be supplied in a wide range to a desired position to some extent. That is, if chlorine dioxide powder or the like is stored in the incense cartridge in Patent Document 2, the gas containing chlorine dioxide generated from the chlorine dioxide powder can be discharged into the atmosphere by the blower fan. Can be supplied.

  However, in the apparatus of Patent Document 2, a motor for driving the blower fan is disposed in the gas passage. For this reason, when chlorine dioxide powder etc. are accommodated in an incense cartridge, since the gas containing chlorine dioxide will always contact a motor, a motor etc. will be damaged in a short period of time. That is, when the apparatus of Patent Document 2 is used as an apparatus for supplying a gas containing chlorine dioxide, the durability of the apparatus is very low, so that it is difficult to use it practically.

  In view of the above circumstances, an object of the present invention is to provide an air purification device that can supply chlorine dioxide over a relatively wide range and can suppress damage to the device due to chlorine dioxide.

An air purifying apparatus according to a first aspect of the present invention is an apparatus for purifying air by supplying chlorine dioxide into the atmosphere, and a package that contains a substance that generates chlorine dioxide, and a case that contains the package inside And an airflow forming means provided in the case for generating an airflow from the inside of the case to the outside of the case, the case having a suction port for introducing air into the case, A discharge port for discharging air to the outside of the case formed above the suction port, and an air flow path connecting the two are formed, and the airflow forming means is disposed in the air flow path. been, has the airflow unit for generating an air flow in the air passage, the air flow path between the outlet and the airflow unit accommodation space in which the package is Ru is located Is provided.

Next, an embodiment of the present invention will be described with reference to the drawings.
The air purification apparatus of the present invention is an apparatus that supplies chlorine dioxide gas into the air, and is characterized in that chlorine dioxide gas can be supplied more effectively into the air.

  The air purifying apparatus of the present invention is characterized by a structure for supplying chlorine dioxide gas into the air, and its size and usage can take various forms. For example, the air purification device of the present invention can be configured to be carried and used by a person (first embodiment), or can be configured to be used on a desk or the like (first embodiment). Further, in any case, it may be formed so as to exhibit the function described later. That is, various external shapes and internal structures can be adopted as the external shape and internal structure of the air purification device of the present invention.

  Hereinafter, an example of an embodiment according to the air purification device of the present invention, that is, an example of a structure carried by a person (first embodiment) and an example of a structure used in a desk (second embodiment) will be described. To do.

(A structure that people carry and use)
The air purification device of the first embodiment includes a case 1, a package 10 accommodated in the case 1, and airflow forming means, and is formed in a portable size.

  First, the package 10 contains a substance that generates chlorine dioxide. The packaging body 10 may be one in which the substance is housed in a bag-shaped housing body, or the housing body in which the substance is housed may be housed in a small case, and the form thereof is not particularly limited. . Further, a substance that generates chlorine dioxide is not particularly limited. For example, it is possible to use a granular material that is formed into a granular shape by supporting chlorite on a supporting member. In this case, if the granular material reacts with carbon dioxide gas (for example, carbon dioxide) or water in the air, chlorine dioxide gas (hereinafter simply referred to as chlorine dioxide) is generated, so chlorine dioxide can be generated easily. Can do.

  The airflow forming means includes a motor M and an impeller 2 attached to the main shaft of the motor M. The impeller 2 has a structure capable of generating an air flow from the center toward the outer edge when rotated (see FIG. 5). This impeller 2 is equivalent to the airflow formation part said to a claim. Note that how the motor M and the impeller 2 are arranged in the case 1 will be described later.

  As shown in FIG. 1, the case 1 has a suction port ip at the lower front portion and a discharge port op at the upper end, and an air flow path F that connects the suction port ip and the discharge port op (see FIG. 3). Is formed inside (see FIGS. 3 and 5). The air flow path F is provided with an impeller 2 of airflow forming means on the upstream side (suction port ip side), and in the accommodation space FA provided between the impeller 2 and the discharge port op. A package 10 is arranged.

  Therefore, if the impeller 2 of the airflow forming means is operated (rotated), air is introduced into the case 1 from the suction port ip and is discharged to the outside through the air flow path F from the discharge port op. A packaging body 10 is disposed in the accommodation space FA of the air flow path F, and the packaging body 10 contains a substance that generates chlorine dioxide. Then, since chlorine dioxide is also contained in the air discharged to the outside from the discharge port op, chlorine dioxide can be supplied from the case 1 to the outside.

  Moreover, since the air flow is forcibly formed by the impeller 2 of the air flow forming means and chlorine dioxide is discharged out of the case 1 by the air flow, not only the periphery of the case 1 but also the air containing chlorine dioxide. A wide range can be supplied.

  And the air purification apparatus of 1st embodiment is formed in the magnitude | size which a person can carry. For this reason, if a person carries and uses, the air which a person breathes can be purified by chlorine dioxide not only indoors but also outdoors. Therefore, the possibility that a person will be infected with a virus or the like can be reduced.

(Description of Case 1)
Next, the case 1 of the air purification device of the first embodiment will be described in detail.

As shown in FIGS. 1 to 7, the case 1 is formed of a main body 1 a and a plurality of covers 1 b to 1 d that are detachably attached to the main body 1 a. Specifically, the cover 1b is attached to the lower front portion of the main body 1a, the cover 1c is attached to the upper front of the main body 1a, and the cover 1d is attached to the lower rear of the main body 1a to form the case 1. .
The cover 1b is provided with a plurality of through-holes that serve as the suction port ip described above.

(Description of the back of Case 1)
First, the back surface of the main body 1a of the case 1 will be described.

  As shown in FIG. 2, a hook portion 1 f is provided on the upper surface of the back surface of the main body portion 1 a of the case 1. The hook portion 1f is a portion through which a string or the like is passed. If the string or the like is passed through the hook portion 1f, the air purification device according to the first embodiment can be hung on a bag or the like and carried.

  On the other hand, a cover 1 d is attached to the lower back of the main body 1 a of the case 1. This cover 1d is provided to isolate the motor M and the battery of the airflow forming means provided at the lower back of the main body 1a from the outside.

  As shown in FIGS. 6 and 7, a pair of separation walls W, W extending along the vertical direction of the main body 1a is provided at the lower back of the main body 1a. The pair of separation walls W, W are provided to separate the lower back portion of the main body 1a into a motor housing space for housing the motor M of the airflow forming means and a battery case BC to which a battery is attached. Specifically, the space between the pair of separation walls W and W is provided as a motor housing space, and the space outside the separation walls W and W is provided as a battery case BC.

In the motor housing space, a motor case MC1 for housing the motor M of the airflow forming means is formed. The motor case MC1 is formed by a wall-like member standing on the back surface of the main body 1a of the case 1. The motor case MC1 is provided so as to surround the side surface of the motor M except for a portion through which a wiring connecting the motor M to the switch s and the battery B is passed. And the through-hole is formed in the bottom face (namely, the back surface of the main-body part 1a of case 1) of the part enclosed by this motor case MC1. That is, the inside of the motor case MC1 communicates with a space FB described later through a through hole. And in this motor case MC1, the motor M of the airflow forming means is attached in a state where the main shaft passes through the through hole (that is, the main shaft protrudes into the space FB).
In a state where the motor M has its main shaft passed through the through hole, a packing or the like is provided in the gap between the main shaft and the through hole of the motor M so as to airtightly close the gap while allowing the rotation of the main shaft.

  The case 1 also includes a motor cover 3 that covers the motor housing space. The motor cover 3 is formed in substantially the same shape as the opening of the motor housing space. That is, when the motor cover 3 is attached, the opening of the motor housing space can be closed. Moreover, the motor cover 3 includes a cover portion MC3 that engages with the tip of the motor case MC1. When the motor cover 3 is attached, the cover portion MC3 and the motor case MC1 can be overlapped with each other (see FIG. 3). For this reason. If the motor cover 3 is mounted over the motor housing space, the motor M can be isolated from other parts of the back surface of the main body 1a of the case 1 except for the part through which the wiring is passed. Then, even if a gas containing chlorine dioxide enters the back surface of the main body 1a (that is, the motor housing space) from the space FB through the gap between the main shaft and the through hole, the battery may come into contact with the gas containing chlorine dioxide. Can be lowered.

(Description of the front of Case 1)
Next, the front surface of the main body 1a of the case 1 will be described.

  As shown in FIGS. 3 to 5, in the upper part of the case 1, an accommodation space FA for accommodating the package 10 is formed by the cover 1 c and the upper front part of the main body 1 a. Specifically, the upper portion of the main body portion 1a is recessed from the front surface to the back surface, and the cover 1c is also formed to be recessed from the front surface to the back surface having a substantially arc shape in cross section. Therefore, even if the cover 1c is attached to the front upper portion of the main body 1a, the accommodation space FA for accommodating the package 10 can be formed between the opposing surfaces.

  On the other hand, as shown in FIGS. 3 and 5, a partition d that divides the main body 1 a in the vertical direction is provided at an intermediate portion in the vertical direction on the front surface of the main body 1 a. The partition d is provided so that the tip thereof is in contact with the inner surface of the cover 1c when the cover 1c is attached to the upper front surface of the main body 1a. The partition d has an opening FC in the middle in the left-right direction, the reason for which will be described later.

  Since the structure is as described above, when the cover 1c is attached to the upper front surface of the main body portion 1a, the space surrounded by the front surface of the upper portion of the main body portion 1a, the back surface of the cover 1b, and the partition d, that is, the packaging body 10 is accommodated. The accommodation space FA can be formed.

  Further, the main body 1a and the cover 1c are formed with a discharge port op through which air can pass between the upper end of the main body 1a and the upper end of the cover 1c in a state where the cover 1c is attached to the upper front surface of the main body 1a. It is formed to be. That is, a gap is formed between the upper end of the main body 1a and the upper end of the cover 1c.

  As shown in FIGS. 3 and 5, a space FB for accommodating the impeller 2 of the airflow forming means is formed in the lower part of the case 1 by the cover 1b and the lower front part of the main body 1a. Specifically, the cover 1b has a substantially arc shape in cross section and is formed so as to be recessed from the back surface toward the front surface, and is formed so as to cover the lower front surface of the main body portion 1a. On the other hand, a substantially wall-shaped impeller case HS is provided on the lower front surface of the main body 1a. The impeller case HS is formed in a substantially arc shape when viewed from the front. And the impeller case HS is formed so that the front-end | tip will contact the inner surface of the cover 1b, if the cover 1b is attached to the lower front surface of the main-body part 1a. That is, the impeller case HS is provided such that a space FB for accommodating the impeller 2 is formed by the impeller case HS, the front surface of the main body 1a, and the cover 1b.

  As shown in FIGS. 3 and 5, the impeller case HS is provided at the upper part so as to communicate with the opening FC of the partition d, and the airflow generated when the impeller 2 rotates is generated. It is formed so that it can be effectively supplied to the opening FC. Specifically, the impeller case HS is provided so that the inner surface thereof has an arc shape and the center thereof is located on the rotation shaft of the impeller 2 (that is, the main shaft of the motor M). The impeller case HS is formed such that the inner diameter of the inner surface is slightly larger than the outer diameter of the impeller 2.

Since it is this structure, if the motor M is operated and the impeller 2 is rotated, air can be introduced into the space FB in the case 1 from the suction port ip of the lower cover 1b. It can be moved along the inner surface of the impeller case HS and supplied to the opening FC of the partition d.
Since the air supplied to the opening FC of the partition d flows into the accommodation space FA, it becomes air containing chlorine dioxide generated from the package 10, and this air can be discharged to the outside from the discharge port op.

  Moreover, in the air purification apparatus of 1st embodiment, although the impeller 2 is arrange | positioned in the flow path F (space FB, opening FC, accommodation space FA) through which air flows, the drive part (motor) which drives the impeller 2 M) is not arranged. The motor M is attached to the back surface of the main body 1a isolated from the flow path F. For this reason, possibility that the motor M will contact with chlorine dioxide can be made lower. Then, since the damage of the motor M by chlorine dioxide can be suppressed, the lifetime of the apparatus can be extended.

  Here, in a state where the impeller 2 is rotated by the motor M, air flows from the space FB toward the accommodation space FA, so that chlorine dioxide generated in the package 10 in the accommodation space FA flows into the space FB. Never do. However, in a state where the motor M is not operated, that is, in a state where the impeller 2 is not rotating, chlorine dioxide is heavier than air, and therefore enters the space FB through the opening FC. At this time, it is desirable to prevent chlorine dioxide from flowing to the motor M side as much as possible. Therefore, in the air purification device of the first embodiment, the portion connecting the accommodation space FA and the space FB, that is, the wall surface in the vicinity of the opening FC becomes an inclined surface that goes from the back surface to the front surface as it goes downward. It is desirable that it be formed. If such an inclined surface is formed, even if chlorine dioxide flows from the accommodation space FA through the opening FC to the space FB in a state where the motor M is stopped, the chlorine dioxide is sucked into the suction port ip of the lower cover 1b. Therefore, the possibility that the motor M is damaged can be reduced. Further, since chlorine dioxide flows toward the suction port ip of the lower cover 1b, it is possible to obtain the effect that chlorine dioxide can be supplied into the air from the suction port ip even when the motor M is not operated. .

  In addition, the air purification apparatus of 1st embodiment employ | adopts the structure that the motor M which is a drive source which rotates the impeller 2 does not contact chlorine dioxide as much as possible as mentioned above. However, when the packing of the through hole deteriorates due to long-term use or the like, chlorine dioxide may leak to the back side of the main body 1a and come into contact with the motor M. Therefore, it is desirable to employ a motor M that has been subjected to acid resistance treatment in preparation for such contact. If the acid resistance treatment is performed, even if chlorine dioxide comes into contact with the motor M, the motor M can be prevented from being damaged by the chlorine dioxide, so that the performance of the motor can be suppressed from being lowered. The acid-resistant treatment is a treatment such as using a material with high acid resistance for the parts constituting the motor M, or applying an acid-resistant coating to each part or the entire motor M, but is not particularly limited. .

(Air purification device of the second embodiment)
Similar to the air purification device of the first embodiment, the air purification device of the second embodiment includes a case 21, a package 10 accommodated in the case 21, and airflow forming means. Unlike the air purification apparatus of the first embodiment, the air purification apparatus of the second embodiment is used on a desk or the like.

  Since the air purification device of the second embodiment has a structure substantially equivalent to that of the air purification device of the first embodiment, the portion of the configuration substantially equivalent to the air purification device of the first embodiment is A brief explanation will be given by omitting it as appropriate.

First, the packaging body 10 can use substantially the same thing as the air purification apparatus of 1st embodiment.
The airflow forming means includes a motor M and an impeller 22 attached to the main shaft of the motor M. Although the shape of the impeller 22 is different from that of the impeller 2 in the air purification apparatus of the first embodiment, the impeller 22 is common in that it has a structure capable of generating an air flow from the center toward the outer edge when rotated. . In addition, in the air purification apparatus of 2nd embodiment, since the structure which arrange | positions the motor M and the impeller 2 in the case 21 differs, this point is mentioned later.

  As shown in FIGS. 8 to 13, the case 21 has a suction port ip at the lower front surface and a discharge port op at the upper end, and an air flow path F that connects the suction port ip and the discharge port op is provided inside. (See FIGS. 10 and 12). The air flow path F is provided with an impeller 22 of airflow forming means on the upstream side (suction port ip side), and in the accommodation space FA provided between the impeller 22 and the discharge port op. A package 10 is arranged. The structure of the case 21 in the air purification device of the second embodiment is also substantially equivalent to the case 1 of the air purification device of the first embodiment.

  Therefore, even in the air purification device of the second embodiment, if the impeller 22 of the airflow forming means is operated (rotated), air is introduced from the suction port ip into the air flow path F of the case 21 and is discharged from the discharge port op. It is discharged outside. And the package 10 is arrange | positioned in the accommodation space FA of the air flow path F, and the substance which generate | occur | produces chlorine dioxide is accommodated in this package 10. FIG. For this reason, since chlorine dioxide is also contained in the air discharged to the outside from the discharge port op, chlorine dioxide can be supplied from the case 21 to the outside.

  Moreover, since the airflow is forcibly formed by the impeller 22 of the airflow forming means and chlorine dioxide is discharged out of the case 21 by the airflow, not only the periphery of the case 1 but also the air containing chlorine dioxide. A wide range can be supplied. In particular, in the air purification device of the second embodiment, the motor M and the impeller 22 are larger than the motor M and the impeller 2 of the air purification device of the first embodiment. For this reason, since the airflow which generate | occur | produces by rotation of the impeller 22 can be strengthened, the air containing chlorine dioxide can be supplied more extensively than the air purification apparatus of 1st embodiment. Therefore, if the air purification apparatus of 2nd embodiment is set | placed on a desk etc., the vicinity of a desk and the air of the circumference | surroundings can be purified with chlorine dioxide.

In the air purification apparatus of the second embodiment, the method for controlling the operation of the motor M, that is, the supply of chlorine dioxide to the outside is not particularly limited.
For example, it is assumed that the motor M is continuously operated when the switch S is ON, and the motor M is stopped when the switch S is OFF. In this case, if the stop of the operation of the motor M is controlled by turning on and off the switch S provided on the side surface, the supply amount of chlorine dioxide can be controlled.
Further, an electronic board for controlling the operation of the motor M is provided, and when the switch S is turned ON, the stoppage of the operation of the motor M is automatically controlled according to a time table set in advance on the electronic board. Also good. In this case, unlike the case described above, it is not necessary for a person to adjust the supply stop of chlorine dioxide, and there is an advantage that the amount of chlorine dioxide supplied to the atmosphere can be adjusted to an appropriate amount. In addition, if the motor M is operated intermittently, the consumption of the battery B can be suppressed, so that continuous operation can be performed for a certain long period of time. For example, a method of operating the motor M in a cycle of operating for 5 seconds (operating the motor M) and stopping for 25 seconds (stopping the motor M) can be employed.
Furthermore, when operating for a certain period with the switch S turned ON, it becomes difficult to notice an operation stop due to a battery exhaustion. Therefore, when performing such an operation, it is preferable to turn on a lamp for warning of battery replacement because the user can easily determine the battery replacement time.

(Description of case 21)
Next, the case 21 of the air purification device of the second embodiment will be described in detail.
In addition, the part which has a structure substantially equivalent to case 1 of the air purification apparatus of 1st embodiment omits description suitably.

As shown in FIGS. 8 to 13, the case 21 is formed by a main body portion 21 a and a plurality of covers 21 b to 21 d that are detachably attached to the main body portion 21 a. Specifically, the cover 21b is attached to the lower front part of the main body part 21a, the cover 21c is attached to the upper front part of the main body part 21a, and the cover 21d is attached to the lower rear part of the main body part 1a. .
The cover 21b is provided with a plurality of through-holes that serve as the suction port ip described above.
In addition, since the case 21 of the air purification device according to the second embodiment is assumed to be used by being placed on a desk or the like, the main body portion 21a of the case 21 has a flat bottom surface.

(Description of the back of the case 21)
First, the back surface of the main body 21a of the case 21 will be described.

  As shown in FIGS. 9 and 10, a cover 21 d is attached to the lower part of the back surface of the main body 21 a of the case 21. This cover 21d is provided to isolate the motor M and the battery B of the airflow forming means provided at the lower back of the main body 21a from the outside.

Unlike the main body portion 21a of the air purifying apparatus of the first embodiment, a motor case MC1 is formed in the lower back portion of the main body portion 21a by a recess recessed toward the front surface (see FIG. 13). The motor case MC1 is formed in a shape substantially similar to the outer shape of the motor M. For example, when a cylindrical motor M is used, it is formed in a bottomed cylindrical shape whose inner diameter is slightly larger than the outer diameter of the motor M. A through hole is formed in the bottom of the motor case MC1. That is, the inside of the motor case MC1 communicates with a space FB described later via the through hole. And in this motor case MC1, the motor M of the airflow forming means is attached in a state where the main shaft passes through the through hole (that is, the main shaft protrudes into the space FB).
In a state where the motor M of the airflow forming means passes the main shaft through the through-hole, a packing or the like is provided in the gap between the main shaft and the through-hole of the motor M so as to block the gap in an airtight manner while allowing the rotation of the main shaft. Is provided.

  In addition, the case 21 includes a motor cover 23 arranged to cover the motor case MC1, in other words, to isolate the motor case MC1 from the outside. The motor cover 23 also serves as a battery case, and the battery B is attached to the surface opposite to the motor case MC1. For this reason, if the motor cover 23 is attached to the lower back of the main body 1a, the motor M can be isolated from the battery B and the outside, except for the portion through which the wiring passes. Then, even if a gas containing chlorine dioxide enters the motor case MC1 from the space FB through the gap between the main shaft and the through hole, the possibility that the battery B comes into contact with the gas containing chlorine dioxide can be reduced.

(Description of the front of the case 21)
Next, the front surface of the main body 21a of the case 21 will be described.
The front surface of the main body portion 21a of the case 21 has substantially the same configuration as that of the case 1 of the air purifying apparatus of the first embodiment except that the motor case MC1 is provided so as to protrude into the space FB. Have.

  As shown in FIGS. 9 to 12, in the upper part of the case 21, an accommodation space FA for accommodating the package 10 is formed by the cover 21 c and the front upper part of the main body 21 a. Further, on the front surface of the main body portion 21a, a partition d that divides the main body portion 21a in the vertical direction is provided at an intermediate portion in the vertical direction (see FIG. 12). For this reason, when the cover 21c is attached to the upper front surface of the main body portion 21a, a space surrounded by the front surface of the upper portion of the main body portion 21a, the rear surface of the cover 21b, and the partition d, that is, an accommodation space FA for accommodating the package 10 is formed. be able to. As in the case 1 of the air purification device of the first embodiment, air is passed between the upper end of the main body 21a and the upper end of the cover 21c in a state where the cover 21c is attached to the upper front surface of the main body 21a. A discharge port op that can be formed is formed.

  As shown in FIGS. 10 and 12, a space FB for accommodating the impeller 22 of the airflow forming means is formed in the lower portion of the case 21 by the cover 21b and the lower front portion of the main body portion 21a. A substantially wall-shaped impeller case HS is provided on the lower front surface of the main body 21a. The impeller case HS is provided such that a space FB for accommodating the impeller 22 is formed by the impeller case HS, the front surface of the main body portion 21a, and the cover 21b. Moreover, the impeller case HS is provided at the upper part so as to communicate with the opening FC of the partition d, and is formed so that the airflow generated when the impeller 22 rotates can be effectively supplied to the opening FC. Has been.

Since it is this structure, if the motor M is operated and the impeller 22 is rotated, air can be introduced into the space FB in the case 21 from the suction port ip of the lower cover 21b. It can be moved along the inner surface of the impeller case HS and supplied to the opening FC of the partition d.
Since the air supplied to the opening FC of the partition d flows into the accommodation space FA, it becomes air containing chlorine dioxide generated from the packaging body 10 and is discharged to the outside from the discharge port op.

  In the air purification device of the second embodiment, unlike the air purification device of the first embodiment, the blades of the impeller 22 are arranged between the outer surface of the motor case MC1 and the impeller case HS. However, as described above, the impeller 22 has a structure that can generate a flow of air from the center toward the outer edge when the impeller 22 rotates as in the impeller 2. Therefore, as described above, the introduced air can be moved along the inner surface of the impeller case HS.

  In the air purification apparatus of the second embodiment, the motor case MC1 is disposed in the flow path F (the space FB, the opening FC, the accommodation space FA) through which air flows. It is isolated from. Therefore, since possibility that the motor M will contact with chlorine dioxide will become low, the damage of the motor M by chlorine dioxide can be suppressed, and the lifetime of an apparatus can be lengthened.

  Also in the air purification device of the second embodiment, the wall surface in the vicinity of the opening FC is formed to be an inclined surface from the back surface to the front surface as it goes downward. Therefore, even when the motor M is stopped, it is difficult for chlorine dioxide to flow to the motor M side, so that the possibility that the motor M is damaged can be reduced. Further, such a structure also provides an effect that chlorine dioxide can be supplied into the air from the suction port ip even when the motor M is not operated.

Further, since chlorine dioxide is a gas heavier than air, as described above, chlorine dioxide flows from the accommodation space FA into the space FB when the motor M is stopped (when the operation is stopped, the battery is dead, etc.). For this reason, if the motor M is left in a stopped state, gas may accumulate in the space FB. In this case, the accumulated gas may flow from the through hole of the motor case MC1 to the back side. Then, chlorine dioxide may come into contact with a battery, a substrate, etc., and troubles due to metal corrosion or the like may occur.
Therefore, in the air purification device of the second embodiment, the suction port ip is formed so that the opening located at the lowermost portion of the suction port ip is lower than the motor M or the substrate that controls the operation of the motor or the like. ing.
In this case, even if chlorine dioxide accumulates in the space FB, the chlorine dioxide can be discharged to the outside from the suction port ip before contacting the motor M and the substrate, so that the motor M and the substrate are damaged by chlorine dioxide. This can be prevented.
In particular, if the inner surface of the impeller case HS is formed so as to face the opening located at the lowest part of the suction port ip, it is preferable because the accumulated chlorine dioxide is easily guided to the suction port ip and discharged to the outside. .

  Furthermore, even in the air purification device of the second embodiment, if a motor M that has been subjected to acid resistance treatment is employed, even if chlorine dioxide contacts the motor M, the motor M is damaged by chlorine dioxide. Since it can prevent, the performance of a motor can suppress a fall.

  The air purification apparatus of the present invention is suitable for an apparatus for purifying air by sterilizing viruses or the like in the air sucked by a person in a place where there are many germs such as viruses in the air.
