Thus, when the housing main body portion 422 and the housing cap portion 424 are engaged with each other, the filter portion 44 can be stably positioned in the inner space of the housing portion 42, and the housing cap portion 424 So that the filter unit 44 can be easily replaced by separating it from the housing main body 422. [

At this time, one of the housing main body portion 422 and the housing cap portion 424 may have an intake port 422a connected to the first hose 31 and an exhaust port 422a connected to the second hose 32 424a may be located. The first and second hoses 31 and 32 and the housing part 42 are connected to each other so that the air supplied from the first hose 31 can pass through the interior of the housing part 42 and flow to the second hose 32. [ . 1, the first and second hoses 31 and 32 may further include connection members 31a and 32b for connection with the intake port 422a and the exhaust port 424a of the housing portion 42 have. Thus, the first and second hoses 31 and 32 and the housing part 42 can be stably fastened.

The housing main body portion 422 and the housing cap portion 424 are coupled using a screw 422b formed on the inner surface of the housing main body portion 422 and a screw 424b formed on the outer surface of the housing cap portion 424 coupled thereto. Or separation. In other words, the housing cap portion 424 can be rotated by rotating the housing cap portion 424 in one direction located inside the opened one side of the housing main portion 422, and by rotating them in the opposite direction, they can be separated. However, the present invention is not limited thereto, and the housing main body portion 422 and the housing cap portion 424 can be joined and separated by various structures and methods.

The housing main body portion 422 and the housing cap portion 424 may be made of a material that can withstand fire in a fire scene or the like. For example, the housing main body portion 422 and the housing cap portion 424 may be made of a metal material. However, the present invention is not limited thereto, and the housing main body portion 422 and the housing cap portion 424 may be made of various materials.

At this time, a packing member 424c for stably fixing the filter unit 44 can be positioned inside the housing cap unit 424 so as not to leak air. The packing member 424c can have a variety of materials and configurations. As an example, in this embodiment, the packing member 424c may be composed of an o-ring composed of an elastic member such as rubber. Thereby preventing air leakage and effectively providing air to the user.

In this embodiment, the window member 422c having the light transmitting property may be positioned in the housing main body 422 in correspondence with the inner space so that the inner space can be seen. More specifically, it can be formed by removing a part of the housing main body portion 422 to form an opening portion 422d and positioning the window member 422c on the opening portion 422d. The window member 422c can be made of various materials, for example, transparent glass or the like. The housing main body portion 422 and the window member 422c may be coupled in various structures, schemes, and the like. For example, the housing main body portion 422 and the window member 422c can be formed simultaneously by a heterogeneous injection method, thereby simplifying the manufacturing method.

As shown in FIG. 4, the filter unit 44 positioned in the inner space of the housing unit 42 includes a filter body 442 for purifying the air and a filter unit 442 for determining the degree of contamination of the filter body 442 And a pollution judging member 444 located corresponding to the filter body 442. [ The filter unit 44 may further include a vibration damping film 446 to improve the cleaning effect and may include a filter body 442 for receiving the filter body 442, the contamination judging member 444, the vibration damping film 446, (448).

The filter receiver 448 receives various configurations for cleaning the air (i.e., the filter body 442, the contamination determining member 444, the vibration damping film 446, and the like) to integrate the filter unit 44. Thus, the process of attaching and detaching the filter unit 44 to the inner space of the housing unit 42 can be simplified.

The shape of the filter receiver 448 may have a variety of shapes that can fit into the interior space of the housing portion 42. For example, in this embodiment, the inner space of the housing part 42 has a cylindrical shape and the filter receiver 448 has a cylindrical shape corresponding thereto. However, the present invention is not limited to this, and the shape of the housing part 42 and the filter receiver 448 can be variously modified.

More specifically, the filter receiver 448 may include a side surface portion 448a constituting a side surface and a cap portion 448b coupled to an end portion of the side surface portion 448a. The cap portion 448b can be separated from the side surface portion 448a and the cap portion 448b can be coupled to the side surface portion 448a after replacing the filter main body 442, the dustproof film 446 and the like. That is, the filter main body 442, the vibration damping film 446, and the like can be replaced by a simple process. At this time, the hole 449 through which the air flows is positioned in the cap portion 448b, so that the air can flow well into the filter receiver 448 and flow out well. For example, the cap portion 448b may have a lattice shape so that the air can flow well while maintaining a stable structure.

In this embodiment, the contamination judging member 444 is located inside the filter receptacle 448 and the contamination judgment inside the filter receptacle 448 through the window member 422c and the side surface portion 448a located in the housing main body portion 422 Member 444 is seen. Therefore, the side surface portion 448a is made of a light-transmitting material so that the contamination judging member 444 inside the filter receiver 448 can be easily seen through the window member 422c. In one example, the side surface portion 448a may have a transparent resin (for example, polycarbonate resin) shape. Since the cap portion 448b is coupled to the end portion of the side surface portion 448a, various materials such as a translucent material or an opaque material can be used. The cap portion 448b can be fixed with various resins.

The filter body 442 located inside the filter receiver 448 may be composed of various materials capable of purifying the air. In one example, the filter body 442 may comprise activated carbon that has porosity to allow for a rapid chemical reaction to occur with a high absorbency and adsorptivity by a large surface area. At this time, if a certain size of activated carbon particles are used as the filter body 442, air can flow smoothly between the activated carbon particles. And an adsorbent (for example, a synthetic zeolite) having uniformly fine pores and having excellent adsorption ability to adsorb molecules to the pores. Thus, using activated carbon and adsorbent can effectively remove pollutants in the air. However, the present invention is not limited thereto, and the filter body 442 may be formed of various materials.

The vibration damping film 446 may be positioned between the filter main body 442 and the filter main body 442 (more specifically, the cap portion 448b adjacent to the vent 424a and / or the intake port 422a). The anti-vibration film 446 may be formed of a surface-treated fabric (for example, non-woven fabric, cotton, etc.) to remove dust. Dust in the air can be effectively removed by the anti-vibration film 446. However, the present invention is not limited thereto, and the material and structure of the anti-vibration film 446 can be variously modified.

The contamination judging member 444 is positioned between the filter body 442 and the filter body 442 (more specifically, the portion of the side surface portion 448a seen by the window member 422c). The pollution judging member 444 may be composed of various substances which are attached to dust or the like to judge the degree of pollution inside the filter receiver 448. In one example, the contamination judging member 444 may be composed of a fabric having a white color (for example, nonwoven fabric, cotton, etc.). The use of a fabric having a white color allows the degree of contamination to be easily determined by the color change of the contamination judging member 444 while the cost is low. That is, when dust, pollutants, or the like are adhered to the contamination judging member 444 and discolored to yellow, brown, gray, black or the like, it can be judged that the filter body 442 is contaminated. However, the present invention is not limited thereto. Therefore, the contamination determining member 444 can be made of a fabric, a cartridge, or the like in which a reagent or the like capable of measuring the degree of contamination is located, so that the degree of contamination of the contamination determining member 444 can be more objectively determined.

In this embodiment, the contamination judging member 444 may be positioned so as to surround the outer surface of the side surface of the filter body 442. The filter body 442 and the pollution judging member 444 are inserted into the filter receptacle 448 while the pollution judging member 444 is wound on the outer surface of the side surface of the filter body 442, Can be installed. Thus, a simple structure can be obtained. The contamination judging member 444 is entirely disposed on the outer surface of the filter body 442 to determine whether the pollution judging member 444 is contaminated through the window member 422c regardless of the position of the filter body 442 . However, the present invention is not limited thereto.

According to the present embodiment, the purifier 40 is located between the air cylinder 10 and the mask 20 (more precisely, between the first pressure reducing system 52 and the second pressure reducing system 54). Therefore, even if the filter system of the air charger (not shown) that charges air in the air canister 10 does not operate properly, the user's health and life can be safely secured. In addition, even when the filter system of the air charger is operated, the air pollution degree can be further reduced, so that the user's health and life can be kept more secure.

Since the degree of contamination of the filter main body 442 can be easily grasped by the pollution judging member 444 and the window member 422c, the point of time of replacement of the filter main body 442 can be accurately known. Thus, the health and life of the user can be secured and waste of the filter body 442 can be reduced.

Hereinafter, a purifier according to another embodiment of the present invention will be described in detail with reference to FIGS. 5 and 6. FIG. 5 and 6, the same or similar parts as those described above are not described in detail, and the different parts are described in detail.

FIG. 5 is a perspective view showing a pollution judging member and a filter body of an air purifier for an air purifier according to another embodiment of the present invention. FIG. For the sake of clarity and simplicity, only the contamination judging member and the filter body are shown in Fig. 5, and the other components are the same as or very similar to those in the embodiment referring to Figs.

5, in this embodiment, the contamination judging member 444 is constituted by a partition wall partitioning a space inside the filter body 442, and a filter body 442 is disposed in a space partitioned by the partition wall. do. The contamination judging member 444 may be composed of a structure formed by laminating various white fabrics (nonwoven fabric, cotton, etc.). Even if the contamination judging member 444 is constituted by the partition wall as described above, at least the end portion of the contamination judging member 444 is located on the side portion 448a side, so that the contamination of the contamination judging member 444 by the window member 422c and the side surface portion 448a Can be confirmed. Thus, problems such as collision of the filter main body 442 due to high-pressure air passing through the filter main body 442, breakage of the filter main body 442 and collapse of the filter main body 442 and reaching the user can be prevented.

6 is an exploded perspective view showing an air purifying apparatus for an air purifier according to another embodiment of the present invention.

As shown in Fig. 6, in this embodiment, a fixing portion 448c on which the contamination judging member 444 is fitted may be formed on the inner surface of the filter receiver 448. Fig. The contamination judging member 444 can be stably positioned inside the filter receiver 448 by sandwiching the contamination judging member 444 in the fixing portion 448c. At this time, in this embodiment, the contamination judging member 444 can be positioned to correspond to a part of the filter receiver 448. [ Accordingly, it is possible to reduce the area of the contamination judging member 444 and reduce the cost.

The outer surface of the filter receiver 448 and the inner surface of the housing portion 42 may be formed with engaging portions 448d and 42d that are engaged with each other. The filter receptacle 448 can be positioned inside the housing portion 42 with the engaging portion 448b of the filter receptacle 448 engaged with the engaging portion 42d of the housing portion 42. [ Thereby, the fixing stability of the filter receiver 448 can be improved and the contamination judging member 444 located only in a part of the filter receiver 448 can be stably positioned at a position corresponding to the window member 422c. In this case, although grooves and projections are used as the engaging portions 448d and 42d in the drawing, it is needless to say that the engaging portions 448d and 42d of various structures and schemes can be used.

Features, structures, effects, and the like according to the above-described embodiments are included in at least one embodiment of the present invention, and are not necessarily limited to only one embodiment. Further, the features, structures, effects, and the like illustrated in the embodiments may be combined or modified in other embodiments by those skilled in the art to which the embodiments belong.
