Referring to fig. 2, and referring to fig. 3 and 4, the filter housing 5 of the present application is substantially in the shape of a truncated cone with a large top and a small bottom, and is open at the top. The filter cover 5 comprises a circular bottom wall 51, a hollow cylinder 52 and a circular wall, wherein the hollow cylinder 52 extends upwards from the center of the bottom wall 51, the circular wall extends upwards from the bottom wall 51 and surrounds the hollow cylinder 52, and a hollow cavity 521 with an open top is arranged in the hollow cylinder 52. The hollow cylinder 52 is connected with the bottom of the exhaust pipe 3 to install the filter cover 5 at the lower side of the pot cover and cover the air inlet 31 of the exhaust pipe 3. The annular wall and the hollow cylinder (52) are provided with a plurality of through holes for filtering and exhausting. This application cooking utensil's filter-mantle 5 can reliably be fixed to the pot cover downside through simple rotary motion, and the installation and the dismantlement of filter-mantle 5 are simpler, and convenience of customers washs filter-mantle 5 at ordinary times.

In this embodiment, the annular wall includes two layers, namely a first annular wall 53 located at the outer side and a second annular wall 54 located at the inner side, and the gas in the cooking cavity can enter the air outlet of the hollow cavity 521 after passing through the first annular wall 53, the second annular wall 54 and the hollow cylinder 52. The multi-layer annular wall can improve the filtering effect and reduce the exhaust speed. The number of the multi-layered annular walls is not particularly limited, and may be provided in more than two layers, for example, a third annular wall may be further provided between the first annular wall 53 and the second annular wall 54.

In this embodiment, the top of the hollow cylinder 52 is provided with an internal thread, the bottom of the exhaust pipe 3 is provided with an external thread, the bottom of the exhaust pipe 3 protrudes out of the bottom side of the pot cover, the filter cover 5 is assembled upwards, the external thread of the exhaust pipe 3 is connected with the internal thread of the filter cover 5, and the bottom of the exhaust pipe 3 extends into the hollow cavity 521 of the filter cover 5, wherein a distance a of 1mm-10mm is kept between the air inlet 31 and the bottom surface 522 of the hollow cavity 521, so as to ensure smooth exhaust.

The filter cover 5 is further provided with a mounting portion 55 protruding downwards from the bottom wall 51, the mounting portion 55 is hexagonal, the mounting portion 55 can be pinched by hands to rotate the filter cover 5, and operation is convenient.

In the present embodiment, the filter cover 5 is made of metal, and may be made of high temperature resistant safe plastic.

The filter housing 5 will be described in detail below with respect to the structural design for filtration.

The through holes include a plurality of first through holes 531 uniformly distributed on the first annular wall 53 and a plurality of second through holes 541 uniformly distributed on the second annular wall 54, and the maximum sizes of the first through holes 531 and the second through holes 541 are between 0.1mm and 2mm, so that larger particles are prevented from entering the filter housing 5 to influence exhaust. The first through hole 531 and the second through hole 541 are both circular, so that the manufacturing is convenient, and the diameter of the first through hole 531 is larger than that of the second through hole 541, so that the effect of gradual filtering can be achieved from outside to inside.

The first through holes 531 and the second through holes 541 are arranged in a matrix, and the first through holes 531 and the second through holes 541 are arranged in a staggered manner in the radial direction of the filter housing 5, that is, a plurality of vertical rows formed by arranging the first through holes 531 and a plurality of vertical rows formed by arranging the second through holes 541 are staggered in the radial direction, so that the airflow entering the first annular wall 53 from the first through holes 531 can pass through the second through holes 541 and enter the second annular wall 54 after moving relative to the radial direction. The design can prolong the flow path of the airflow and slow down the exhaust speed.

Similarly, the first through holes 531 and the second through holes 541 are arranged in a staggered manner in the height direction of the filter housing 5, and it can be understood that a plurality of transverse rows formed by arranging the first through holes 531 and a plurality of transverse rows formed by arranging the second through holes 541 are staggered in the height direction, so that the airflow entering the first annular wall 53 from the first through holes 531 can pass through the second through holes 541 and enter the second annular wall 54 after moving in the height direction, thereby extending the gas flow path and reducing the exhaust speed.

The through holes further include a plurality of third through holes 523 uniformly distributed on the side wall of the hollow cylinder 52, the third through holes 523 are also arranged in a matrix, and the size of the third through holes 523 is larger than that of the second through holes 541, so as to ensure that fine particles in the air flow entering the second annular wall 54 can smoothly enter the air inlet 31. Similar to the way of staggering the second through holes 541 and the first through holes 531, the third through holes 523 are staggered from the second through holes 541, which can also extend the exhaust path and slow down the exhaust speed.

Referring to fig. 2, a gap B is formed between the top surfaces of the first annular wall 53 and the second annular wall 54 and the bottom surface of the lid, and the gap is smaller than the diameter of the second through hole 541, so as to prevent larger particles from entering the filter housing 5 through the gap B and affecting the filtering effect. Preferably, this clearance is less than 0.5 mm. As another alternative, the top surface of the first annular wall 53 or the second annular wall 54 abuts against the bottom surface of the lid, i.e. there is almost no gap, so as to prevent larger particles from entering the filter housing 5 through the gap B and affecting the filtering effect.
