[0002] Water heating equipment mainly refers to gas boilers, which are usually used in temperature regulation and hot water supply places with large areas and large hot water consumption. It generates heat energy by burning gas, and then uses a circulating water pump to transfer the heat energy to water, thereby realizing the heating of water. When using the water heating equipment, cold water needs to be continuously introduced into the equipment, and then the water is heated to facilitate the use of water. However, when water continuously enters the equipment, in order to ensure the cleanliness of the water and avoid the accumulation of impurities in the water in the equipment, which affects the normal use of the equipment, a filtering structure is often required to filter the water. However, when the current filtering structure is in use, the filtering structure needs to be frequently replaced to ensure the filtering effect of the filtering structure. However, since the filtering structure is located inside the equipment, the situation of not being replaced in time often occurs, which affects the filtering effect of the filtering structure on water.

A connecting disk is installed on the surface of the filtering screen. The connecting disk is in close fit with the inner wall of the filtering cylinder and can slide on the inner wall of the filtering cylinder under the push of water flow. A fixed dredging needle is arranged inside the filtering cylinder, and the dredging needle is used for dredging the filtering screen. An installation plate is installed on the inner wall of the device main body. A reset spring is installed at the bottom of the installation plate, and the end of the reset spring is connected to the connecting disk, so as to facilitate the reset of the connecting disk when the filtering screen is in a dredged state.
