[0006] The cleaning structure includes a fixing cap, a movable plate, a fixing column, a wiping cotton rack and a card slot, and the fixing column is arranged at the bottom of the front end of the installation cover.

[0007] Preferably, a movable plate is arranged on the outer side of the fixing column, a card slot is opened inside the movable plate, a wiping cotton rack is arranged inside the card slot, and a fixing cap is arranged at the top end of the fixing column.

[0008] Preferably, the fixing cap is sleeved on the top end of the fixing column, and a threaded connection is formed between the fixing cap and the fixing column.

[0009] Preferably, the wiping cotton rack is inserted into the inner part of the clamping groove, and an interference fit is formed between the wiping cotton rack and the clamping groove.

[0010] Preferably, one end of the movable plate is sleeved on the outer side of the fixed column, and a movable connection is formed between the movable plate and the fixed column.

[0011] Preferably, the sealing structure includes an installation groove, a sealing ring and a connection groove. The installation groove is opened in the inner part of the front end of the alarm device main body. A sealing ring is arranged inside the installation groove, and the connection groove is arranged inside the installation cover.

[0012] Preferably, an external thread is arranged on the outer side of the front end of the alarm device main body, and an internal thread is arranged on the inner side of the installation cover. A threaded connection is formed between the alarm device main body and the installation cover.

[0013] A CO alarm device for a water heater provided by the present utility model has the following advantages:

[0014] By using the buzzer alarm, an alarm can be given when the CO sensor detects CO, reminding the user to pay attention to detecting the problem of CO leakage, making the alarm device main body safer during use. And through the coordinated use of the movable plate, the fixed column and the wiping cotton rack, when it is necessary to clean the dust or impurities on the middle mirror surface of the installation cover, the user only needs to hold the movable plate and rotate it one circle to one side, and then the mirror surface can be cleaned by the wiping cotton rack, making the cleaning more convenient;

[0015] By using the installation groove and the sealing ring in cooperation, the sealing performance of the connection between the alarm device main body and the installation cover can be enhanced, so that water will not easily enter at the connection during use, thereby improving the sealing effect.
