Abstract

The invention discloses an anti-freezing water meter. The water meter comprises a shell and a water meter body, wherein the shell is arranged outside the water meter body. The shell comprises a waterproof layer and a heat preservation layer, and the waterproof layer is arranged outside the heat preservation layer. A water wheel chamber is arranged in the middle of the water meter body, a dial plate chamber is arranged on the upper portion of the water wheel chamber, a meter cover is arranged on the dial plate chamber, a filtering chamber is arranged on the lower portion of the water wheel chamber, and a water inlet pipe is arranged on one side of the water wheel chamber. A heating device is arranged in the meter, so that the heat transfer efficiency is improved; heat preservation and waterprevention are realized on the water meter through the arranged shell; heating is performed through the arranged thermistor when the temperature is lower than a set temperature; heating is performedonly when water in the water meter stops flowing through an arranged flow switch; and the shell and the power source can be taken down when the air temperature is increased through an upper shell anda lower shell.

Description

technical field

[0001] The invention relates to the field of water meters, in particular to an antifreeze water meter. Background technique

[0002] The water meter is an important instrument for counting tap water in the daily life of residents. In the severe cold season, when the water in the water meter starts to flow, the flowing water will not be frozen. When the water in the water meter stops flowing, it is very easy to freeze. Therefore, it often occurs that the water meter freezes and bursts, thereby affecting the water use of a family.

[0003] Therefore, it is necessary to invent a kind of antifreeze water meter to solve the above problems. Contents of the invention

[0004] The object of the present invention is to provide an antifreeze water meter to solve the problems raised in the above background technology.

[0005] In order to achieve the above object, the present invention provides the following technical solutions: an antifreeze water meter, including ...
