[0017] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0018] like Figure 1 , Figure 2 As shown, the utility model provides a portable calling device, including an intercom 1;

[0019] In this embodiment, a dust cover 2 is installed at the speaker call port of the intercom 1, a cavity connected to the dust cover 2 is formed inside the dust cover 2, and an opening connected to the cavity is formed on the dust cover 2, and a dust net 3 is connected to the opening.

[0020] In this embodiment, a brush member 4 is provided in the cavity; the brush member 4 includes a brush cylinder 41, which is provided in the cavity, and is connected to a brush 42 that contacts the dust net 3; gear members 5 are installed at both ends of the brush member 4, and the two gear members 5 rotate and pass through the two sides of the dust cover 2. The gear member 5 includes a rotating rod 51 and a gear body 52, and the two rotating rods 51 are respectively installed at the two ends of the brush cylinder 41, and the ends of the two rotating rods 51 away from the brush cylinder 41 rotate and pass through the two sides of the dust cover 2, and the two gear bodies 52 are respectively installed at the ends of the two rotating rods 51 away from each other.
