Referring to fig. 1 to 4, in one embodiment of the utility model, the respirator 1 comprises:

the washing machine comprises a shell 10, wherein a communication port 101b communicated with the washing cavity 20, a breathing port 101a communicated with the atmosphere and a breathing channel 101e communicated with the breathing port 101a and the communication port 101b are arranged on the shell 10. An insect prevention structure 101g is arranged in the breathing passage 101 e.

According to the technical scheme, the anti-insect structure 101g is additionally arranged in the breathing channel 101e between the breathing port 101a and the communication port 101b, so that insects such as cockroaches and the like are limited to enter the communication port 101b through the breathing channel 101e through the anti-insect structure 101g, and accordingly the insects such as cockroaches and the like are limited to enter the washing cavity 20 through the breathing port 101 a.

Further, the insect-proof structure 101g includes a plurality of insect-proof ribs g1 spaced apart from each other in the extending direction of the breathing passage 101 e. It can be understood that the pest prevention blocking rib g1 can block insects such as cockroaches and prevent the insects such as the cockroaches from passing through the breathing channel 101 e; in addition, the insect-proof rib g1 is simple in structure and easy to prepare and implement. Of course, in other embodiments, the insect-proof structure 101g may also include other structures such as insect-proof net disposed in the breathing passage 101 e.

For the technical scheme of arranging the insect-proof blocking ribs g1, further, one end of the insect-proof blocking rib g1 is connected with the channel side wall of the breathing channel 101e, and a gap is formed between the other end of the insect-proof blocking rib g1 and the channel side wall of the breathing channel 101e to form a breathing gap; in addition, in the extending direction of the breathing passage 101e, any two adjacent insect-proof blocking ribs g1 are arranged in a staggered manner, so that the crawling direction of insects such as cockroaches needs to be changed continuously if the insects such as cockroaches pass through the plurality of insect-proof blocking ribs g1, and the passing difficulty of the insects such as cockroaches can be effectively improved.

It is understood that the rectangular shape here means that the breathing passage 101e is substantially flat and has four side walls, which surround the side walls of the passage, and the vermin-proof barrier rib g1 is connected to three of the side walls at a distance from the remaining side walls.

Furthermore, one end of the insect-proof blocking rib g1 close to the breathing gap extends obliquely in a direction away from the breathing opening 101a, so that the length of the single insect-proof blocking rib g1 can be increased, and the effective length of the insects such as cockroaches to pass through is increased; on the other hand, when insects such as cockroaches pass through the obliquely extending insect-proof blocking rib g1, the insect-proof blocking rib tends to slide downwards, so that the insect-proof blocking rib is not beneficial to standing of the insects such as cockroaches, and the difficulty of the insects such as cockroaches in passing is further improved.

Further, the width w2 of at least one of the breathing gaps is smaller than the width w1 of the breathing opening 101a (see fig. 4); even if some insects pass through the breathing port 101a, they cannot pass through the small breathing gap and cannot enter the communication port 101 b. Optionally, the width of each breathing gap is smaller than the width of the breathing opening 101 a. Typically, at least, the width of the breathing gap near the breathing opening 101a is smaller than the width of the breathing opening 101 a. Further, the width of the breathing gap gradually decreases from the direction away from the breathing opening 101 a; it is understood that, gradually decreasing here means that for any two adjacent breathing gaps, the width of the breathing gap farther than the breathing opening 101a is smaller than the width of the breathing gap closer than the breathing opening 101a, so as to gradually limit the passage of insects with different volume sizes, and prevent a large amount of insects from blocking one breathing gap and affecting the breathing smoothness of the respirator 1.
