Description
Technical Field
[0001] The utility model relates to the technical field of pipeline antifreeze, and more specifically to a water supply device for antifreeze of direct drinking water inlet pipelines. Background Art
[0002] As the temperature drops sharply in winter, the water in the pipes outdoors and in the frozen soil will freeze when it is not flowing, and the water pipes are prone to freezing and cracking. Especially in the severe cold weather conditions in northern regions in winter, the freezing and cracking of water pipes is not uncommon. And for some newly built communities, due to the low occupancy rate, the fluidity of domestic water is not large. It is easy to freeze in such a low temperature environment, causing the water meter pipes to freeze and burst. For direct drinking water pipes entering households, the pipes are usually insulated by wrapping foam or cloth strips around them, but when the temperature is low, the pipes will still freeze. In view of this, we propose a water supply equipment for anti-freezing direct drinking water pipes entering households. Utility Model Content

A cavity 3 is formed between the heating plate 1 and the shell 2, and a heat-conducting component is arranged in the cavity 3 to diffuse the heat. The setting of the cavity 3 facilitates the storage of the heat generated by the heating plate 1. When used on a household pipe with a larger diameter, even if one end of the heating plate 1 slides out from the inside of the shell 2, the heat generated by the other end of the heating plate 1 will still be transmitted through the cavity 3, so that there is residual heat in the entire cavity 3.
[0025] In the present application, baffles 5 are provided at both ends of the shell 2. The baffle 5 on one side is rotatably connected to a blade 6 on its inner side, and the baffle 5 on the other side is provided with an air vent for air circulation in the cavity 3. A motor is provided on the outer side of the baffle 5, and the output shaft of the motor is connected to the blade 6. The motor is used to drive the blade 6 to rotate. When the blade 6 rotates, the heat in the cavity 3 can be quickly transferred.
[0026] In the present application, the heat conducting component includes a heat conducting strip 4, which is arranged on the inner wall of the shell 2 and is inclined. The blade 6 is located on the inner side of the heat conducting strip 4. The airflow generated by the rotation of the blade 6 is guided to one side through the setting of the heat conducting strip 4.
