Description

Personal air purifier

The present invention relates to a personal air purifying device, and more particularly, to a personal air purifying device in which a screen is simply installed on a table and the air purifying device is seated thereon.

Recently, various diseases are newly occurring due to various harmful viruses and bacteria due to the activation of human and material exchanges between countries and environmental pollution.

In particular, the recent transmission method of the coronavirus (COVID-19), which causes acute respiratory diseases, is known as droplet infection transmitted through body fluids such as saliva or runny nose.

In order to prevent droplet infection, it is important not to be with an infected person who has the infectious virus in an enclosed space. It is effective in preventing infection.

On the other hand, a mask is mainly used as a physical method to block splashes. There are cases where it is inevitably necessary to take off the mask because it is difficult to communicate with each other due to the mask when eating or talking with several people. There is an urgent need to develop a device capable of blocking droplets even when not worn.

The first edge 21 and the second edge 22 may form a first angle A1, and the second edge 22 and the third edge 23 may form a second angle A2. ) can be formed.

The third edge 23 and the fourth edge 24 may form a third angle A3, and the fourth edge 24 and the fifth edge 25 may form a fourth angle A4. ) can be formed.

The first angle A1 , the second angle A2 , the third angle A3 , and the fourth angle A4 may be the same.

Here, the first angle A1, the second angle A2, the third angle A3, and the fourth angle A4 ideally form the same angle as the regular octagonal interior angle, but limited to this it is not doing

The most ideal reason when the angles form the same angle as the regular octagonal interior angle is that when the angles form the same angle as the regular octagonal interior angle, the size of the surrounding space S can be formed to be the widest.

The first edge 21 and the sixth edge 26 may form a fifth angle A5, and the fifth edge 25 and the sixth edge 26 may form a sixth angle A6. ) can be formed.

The fifth angle A5 and the sixth angle A6 may be the same.

The first edge 21 and the fifth edge 25 may be disposed parallel to each other, and the third edge 23 and the sixth edge 26 may be disposed parallel to each other.

The vertical frame 10 may further include an uneven portion 13 .

The concave-convex portion 13 is formed at the lower end of the vertical frame 10, and may serve to increase the frictional force with the upper surface of the table (see Fig. 3 (a)).

Specifically, when the vertical frame 10 is seated on the table, sliding on the table is restricted by the concave-convex portion and thus, it may stand stably.

4 and 5 are schematic views showing an air purifier of a personal air purifier according to an embodiment of the present invention, and FIG. 6 is a view for explaining the flow of air in the personal air purifier according to an embodiment of the present invention. It is a schematic diagram.

Specifically, Fig. 5 (a) is a bottom view looking up at the air purifier from the lower side.

4 to 6 , the air purifier 30 of the personal air purifier 1 according to an embodiment of the present invention includes a main body 31 , a blower fan 33 and a purifier 35 . can be provided.

The body part 31 may include a guide hole 312 and a discharge hole 314 .

The guide hole 312 may be formed through a bottom surface facing the table, and may provide a passage through which air in the surrounding space S is sucked into the mounting space C.

The discharge hole 314 may be formed to pass through the front surface T facing the user, and may provide a passage through which air in the mounting space C is exhausted to the upper side of the enclosure space S. .

The discharge hole 314 may further include a wind direction wing portion 313 .

The wind direction wing portion 313 may protrude from the discharge hole 314 and allow the air exhausted from the discharge hole 314 to be discharged with a straightness.

If there is no wind direction wing part 313 , the air exhausted from the discharge hole 314 is scattered in front of the user's face, which may cause inconvenience to the user.

In order to prevent this, in the present invention, the wind direction wing portion 313 is provided to give the air exhausted from the discharge hole 314 straightness, so that the air passes by the side of the user's head.

The guide hole 312 may include a plurality of slice holes 312a.

The plurality of slice holes 312a are formed to be spaced apart along the longitudinal direction of the main body 31, and their lengths may be gradually shortened as the distance from the opposite front surface T increases (FIG. 5(a)). ) Reference).

Specifically, the length of the plurality of slice holes 312a is formed to be gradually shortened as the length of the plurality of slice holes 312a is further away from the opposite front surface T, so that the amount of air sucked into the mounting space C is increased by the opposite front surface (T). The farther away from T), the less intake can be made.

The reason is that, since the user exhales air toward the opposite front surface T, more contaminated air is distributed near the opposite front surface T, and the slice hole 312a close to the opposite front surface T ), the amount of air that can be inhaled is increased so that polluted air can be efficiently sucked in.

The body part 31 may further include a guide wing part 311 .

Figure 5 (b) is a schematic view showing the plurality of slice holes (312a) and the guide wing portion 311, referring to Figure 5 (b), the guide wing portion 311, each It protrudes from the bottom surface of the main body 31 facing the table while being fixed to the inner surface defining the depth of the slice hole.

The guide wing part 311 may guide the air in the surrounding space S to be sucked into the plurality of slice holes 312a.

In addition, the guide wing portion 311, the thickness gradually decreases from the inner surface toward the end toward the table, may be formed to be inclined downward toward the table.

The air in the surrounding space (S) may be moved to the mounting space (C) along the inclination of the guide wing part (311).
