As shown in FIG. 1 and FIG. 2, a cleaning micro-ceramic filter dust mask is disclosed, which comprises: an internal ceramic filter core. 1 and a micro-ceramic filter 200 capable of filtering purified air; and a self-priming dust mask 100 with a front end combined with the micro-ceramic filter 200, which is worn on the wearing body A of the user's face, and at least one side is disposed on one side thereof The mouth a1 has a sleeve portion a2 covering the user's mouth and nose portion on the other side.

The micro-ceramic filter 200 of the present invention includes, in addition to the ceramic filter core 1, a filter housing 4 adjacent to the ceramic filter core 1, and the filter housing 4 is provided with the above-mentioned port a1 a filter outlet 41 connected to each other, and a filter inlet 42 adjacent to the ceramic filter 1 in the other side, in which an activated carbon layer 5 for deodorization is disposed; a ceramic filter core 1 is coated, and the filter shell is simultaneously The body 4 is combined with the positioning housing 2, and the positioning housing 2 is provided with a connecting surface 21 for the filter housing 4 to be exposed, and the other side is provided with a suction port 22 for the air inlet surface of the ceramic filter 1 Show it.

Next, between the ceramic filter core 1 and the filter housing 4, a soft gasket 3 for preventing leakage is provided, so as to prevent air from infiltrating, so that the user does not inhale unfiltered air while breathing; The ceramic filter core 1 can also be provided with an elastic buffering effect to enhance the stability effect.

Further, the activated carbon layer 5 is mainly used for deodorization, but it can be applied to other filter materials to filter acid gases such as chlorine gas, hydrogen chloride, sulfur dioxide, and organic vapor.

In the above, in order to firmly bond the ceramic filter core 1 and the filter housing 4 in the positioning housing 2, an annular protruding retaining ring 23 is provided at the suction opening 22 of the positioning housing 2 for blocking the ceramic filter core 1 The ceramic filter core 1 is prevented from being disengaged from the positioning housing 2; further, the inner wall of the interface 21 of the positioning housing 2 is provided with a plurality of arcuate locking portions 24, and the outer wall of one side of the filter housing 4 is provided with a convex ring 43. Convex ring 43 guide After being inserted into the buckle portion 24, it can be locked, so that the filter housing 4 does not come off the positioning housing 2.

As shown in Fig. 4, the ceramic filter core 1 has an inlet side at one side and an outlet at the other end. The wind surface has a honeycomb-shaped tunnel 11 having an average density of at least 100 mesh per square inch, one end of the tunnel is located on the wind inlet surface, the crucible is opened, and the other end of the tunnel is located on the windward surface, the tunnel 11 The inside is closed by the stopper 12 so that the tunnel 11 cannot be directly passed through. Secondly, the stopper 12 is disposed at an appropriate position inside the tunnel 11 or at the outlet 11 of the air outlet surface. Furthermore, the pores of the pores 11 have micropores 111, so that air is introduced from the pores 11 of the ceramic filter 1 into the wind surface, and is blocked by the inner barriers 12, so that the air D penetrates from the micropores 111. After that, it enters the other tunnels 11, and the pollutant C cannot pass because the volume is larger than the micropores 111. Finally, the purified air flows out from the outlet surface of the ceramic filter 1 to form a bypass state.

Referring to Figure 3 and Figure 4, air D often contains pollutant C, which is contaminated. Object C is a particulate matter having an aerodynamic equivalent diameter of less than 2.5 microns, which is also called fine particulate matter, which often adsorbs or carries toxic or harmful components, so that the longer the residence time in the polluted air D, the easier it is to inhale. Deep in the respiratory tract is very harmful to human health. The ceramic filter core 1 of the present invention has micron pores 111, and the particle size of the pollutant C is larger than that of the micro pores 111. In other words, the micro pores 111 are smaller than the air pollutant C, so that the passage of the pollutant C can be blocked, and the channel 11 is blocked. There are at least one blocking portion 12 therein, and the positions of the blocking portion 12 in each of the holes 11 are different, so that the opening 11 is not straight, so that the air D entering the opening 11 can be forced to pass through the micropores of the hole wall. After 111, it is further transferred into the other holes 11, so that the pollutant C in the air D is captured on the hole wall due to the inability to pass through the micro-pores 111. Please refer to Fig. 4, so the new type can be used in the air D. Most [98%] of the pollutants C [eg chemical smog, bacteria, dust particles and pollen] are filtered out.

Figure 5 shows the micron ceramic filter 200 and the self-priming dust mask 100 The structure diagram is disassembled. The figure shows that after the positioning housing 2 is rotated to one side, the locking portion 24 is disengaged from the convex ring 43, and the positioning housing 2 and the filter housing 4 can be disassembled. Thereafter, the ceramic filter core 1 is removed. Self-positioning housing Take out inside 2. The new type only needs to periodically remove the ceramic filter 1 and then dry it, dry it, or dry it, and then reassemble it, and it can be reused forever, so it is very environmentally friendly. Figure 6 shows that when the ceramic filter core 1 is cleaned with water, the air outlet side of the ceramic filter core 1 faces upward to allow the clean water to rush in, and the other end of the wind inlet side faces downward to cause contamination in the ceramic filter core 1. The material flows out along the water stream, and after drying, drying, drying or drying, it can be resumed.
