In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a filter replaceable dust mask. The filter replaceable dust mask according to the present invention includes a main body 10, a first sewing line 11, a second sewing line 12, a hooking strap 20 and a strap adjusting portion 21. [

The mask body 10 has a wide surface shape so as to accommodate both the ends and the ends of both balls from the nose line starting from below the user's eye to the tip of the jaw so that the wearer can secure the adhesion when worn.

The hook 20 is coupled to the right and left sides of the mask body 10, respectively. The hook 20 plays a role of being fixed to the left and right ears of the user. In addition, a string adjusting portion 21 is formed which can be adjusted appropriately so that the user can fit his or her facial structure.

The string adjusting portion 21 is disposed on the strap 20 coupled to both sides of the mask body 10. The string adjusting portion 21 is constituted by the push adjusting device 22, the through hole 23 and the spring 24. The hooking strap 20 passes through the through hole 23 in the string adjusting portion 21 .

The string adjusting part 21 includes a pressing adjusting device 22 protruding from one side and includes a through hole 23 penetrating through the center of the string adjusting part 21 and inserted and fixed in the string adjusting part 21 The spring (24) is connected to the pushing device (22) and moves up and down during a pressing operation for adjustment of the hooking strap (20).

Hereinafter, the principle of operation of the string adjusting portion 21 of the filter replaceable dust mask according to the present invention will be described in detail.

The mask main body 10 in the form of a face is placed on the face of the user and then the leg gathers 20 to be coupled to both sides of the mask main body 10 are hooked to the right and left ears respectively, The spring 24 is pushed and the through hole 23 is widened by pushing and pushing the push adjusting device 22 protruding from the through hole 21. The wider through holes 23 can be easily pushed and pulled by pulling the gangway 20 because the clamping force is removed.

When the force applied to the push adjusting device 22 is removed, the through hole 23 is narrowed again by the restoring force of the spring inserted into the strap adjusting part 21, and the hooking strap 20 is fixed.

The first sewing line 11 formed at the center of the mask body 10 and the second sewing line 12 formed at the center of the lower portion of the mask body 10 are positioned at the center of the user's face, And the shape of the mouth. When the user mounts the mask, the nose and mouth of the user are placed on the first sewing line 11 and the second sewing line 12 so that the front face of the mask does not press the face of the user like a normal plane mask Thereby maintaining a constant interval. Therefore, it is possible to maximize the fit when the user is engaged in conversation or activities after wearing the mask.

Fig. 2 is a rear view of the filter interchangeable dust mask. Fig. The fixing member 30, the filter fitting portion 40 and the face fixing portion 50 which are coupled to the mask body 10, the hooking straps 20, the string adjusting portion 21 and the mask body 10 are shown.

The fixing member 30 includes a nose clip 31 and a cushioning portion 32. The nose clip 31 and the nose cushion portion 32 are configured to closely fix the mask to the nose protruding from the center of the user's face when the user wears the mask.

The nose clip 31 is inserted into the upper part of the mask body 10. In other words, the nose clip 31 is joined to the upper part of the inner surface of the mask body 10 to which the user's face is contacted. The shape of the nose clip 31 may be appropriately deformed according to the shape of the nose of the user, and a soft material having flexibility and restoring force such as aluminum may be used.

When a general mask is worn, a fine gap is formed in a portion where the face shape mask and the nose contact each other, Fine dust including dust, foreign matter, exhaust gas, and the like are introduced from the external environment by the fine gap. In order to prevent this, a nose clip 31 having excellent ductility and restoring force is inserted into the upper part of the mask body 10 to fix them to the shape of a nose of a different user to remove fine gaps between the user's mask and the mask, Thereby blocking the inflow.

The cushioning portion 32 is formed under the nose clip 31 so as to be disposed on both sides of the nose of the user. In other words, the face of the user is joined to the inner side of the mask body 10 to be contacted. The cushioning portion 32 is preferably made of a soft material such as cotton or plastics foam so that the face of the user and the mask can be more closely contacted.

The cushioning portion 32 eliminates a minute gap formed between the mask and the user's face to improve the protective performance and eliminates the sense of sheath formed by the wire, thereby improving the wearing comfort of the user.

The filter fitting portion 40 is coupled along the inner periphery of the mask body and has an opening at the center for inserting and removing the replaceable filter 60. The openings are preferably circular, but they can be formed in various shapes according to the shape of the filter.

When the user wears the mask, the filter fitting part 40 is brought into close contact with the periphery of the user's respirator, thereby blocking the possibility of dust, fine dust, and exhaust gas flowing from the external environment and improving the protection performance against the conventional mask.

The filter 60 is inserted into an opening formed at the center of the filter fitting portion 40, and thus is configured to surround the user's respiratory apparatus. Therefore, all the paths to the user's respirator are configured to pass through the filter 60 to maximize the shielding rate and protection performance against the external environment.

At this time, the filter fitting portion 40 uses an elastic material for easily inserting and removing the filter. For example, it is preferable that the filter fitting portion 40 is a synthetic rubber type such as neoprene. Synthetic rubbers such as neoprene are excellent in weather resistance and bending resistance, so that there is an effect of reducing failure or defects when the mask is detached.

The face fixing portion 50, which is coupled to the lower portion of the mask body 10, extends to the mask body 10, which accommodates only the face of the user, and serves to additionally receive the bottom of the user's chin.

It is possible to prevent the mask from slipping and coming off even when the user is intensely acted or worn for a long period of time, thereby increasing the wearing comfort and adhesion. The face fixing unit 50 may be formed of the same material as that of the mask body 10, or may be formed of a material having additional functions such as elasticity and air permeability.

3 is a view showing a filter 60 inserted and replaced in a filter interchangeable type dust mask. The filter is constructed in three dimensions through the material and the stitching around the material, without the additional wire or frame that implements the shape.

The material of the filter 60 may be ACF (Activated Carbon Fiber or Activated Carbon Felt). ACF is an adsorbent material that develops molecular size micropores through activation process of carbonaceous material. ACF has an adsorption capacity 1.5 ~ 10 times higher than that of activated carbon used in general filters, and has an adsorption rate of 100 ~ 1,000 times faster than that of activated carbon. Accordingly, in the present invention, by using ACF in the form of nonwoven fabric or fabric, it is used in combination with an electrostatic filter (Melt Blown) used in conventional masks, thereby maximizing the effect as a replaceable filter 60 suitable for cutting yellow dust, fine dust, and exhaust gas .

4 is a view showing the insertion of the filter 60 into the filter fitting portion 40. Fig. As shown in FIG. 4, when the filter 60 having a three-dimensional shape is inserted into the filter fitting portion 40, a three-dimensional shape can be realized even if the user does not wear the mask.

5 shows a cross section of the mask body 10 in which the filter 60 is inserted. The filter replaceable mask according to the present invention comprises a fixing member 30 composed of a mask body 10, a hooking strap 20, a string adjusting portion 21, a nail clip 31 and a nose cushion 32, And a filter 60 inserted into the mask body 10, as shown in FIG.

The hooking rods 20 are coupled to both sides of the mask body 10. In other words, both ends of the hooking straps 20 are fixed to the mask body 10 and adjusted according to the user's facial structure.

The string adjusting portion 21 is located on the hook 20 and is moved up and down by the pressing operation. If a force is applied to the string adjusting portion 21 through a pressing operation, the protruding portion is downwardly adjusted to easily adjust the hooking portion 20. If the pressing operation is removed, the protruding portion is upwardly adjusted The lead 20 is fixed.

The fixing member 30 is composed of a nose clip 31 inserted into the upper part of the mask body 10 and a nose cushion 32 protruding below the nose clip 31.

When the wearer wears the mask 1, the nose clip 31 is bent and deformed along the shape of the nose of the user to be fixed to the face portion.

When the nose clip 31 is fixed along the shape of the nose of the user, the nose cushion 32 is positioned on both sides of the nose so as to reduce the pressure feeling by the nose clip 31, Maximize the rate.

The filter fitting portion 40 is formed along the inner circumference of the mask body 10, and the central portion of the filter fitting portion 40 is formed with an opening. In other words, it is protrudingly formed inside the mask body 10 and is formed in close contact with the user's nose and mouth periphery.

Therefore, the user's respirator is once again sealed from the external environment, thereby improving the blocking rate of dust, fine dust, and exhaust gas.

The face fixing portion 50 is coupled to the lower portion of the mask body 10. In other words, it is coupled to the mask body 10, which accommodates only the user's face, and accommodates it to the user's chin.

Accordingly, the entire periphery of the user's respiratory apparatus is covered to improve the blocking rate with the external environment, and the effect of the mask can be maintained by preventing the wearer from wrestling for a long period of time or engaging in intense activities or leaving.

The filter 60 is replaceable and is configured to be in close contact with the inside of the mask body 10. In other words, it is inserted through the opening in the center of the filter fitting portion 40. At this time, the filter fitting part 40 is brought into close contact with the face of the user, and the respirator is positioned in the opening of the filter fitting part 40 at the center.

Accordingly, the structure in which the user's respirator and the filter 60 are in contact with each other is formed, thereby maximizing the blocking rate against dust, fine dust, and exhaust gas flowing from the external environment.
