Electric heating water faucet

Abstract

The invention discloses an electric heating water faucet which comprises a shell and an inner core, wherein the inner core is arranged in the shell; a water inlet is formed at the bottom of the inner core; and a water outlet is formed at the top of the inner core. The electric heating water faucet further comprises a quartz electric heating film heating tube; the quartz electric heating film heating tube is arranged on the inner core, is communicated with the water inlet and the water outlet and comprises a quartz glass tube and a conducting plate; a conducting layer is arranged on the quartz glass tube; the conducting plate is in contact with the upper end and the lower end of the conducting layer respectively and is respectively connected with a live wire or a zero line; and a closed container of which the outer wall is made of soft material is arranged in the quartz glass tube. The electric heating water faucet has the benefits that when the electric heating water faucet is not in use at ordinary times, if water in the quartz glass tube is frozen, and the volume is expanded, the pressure of the water in the quartz glass tube is increased to extrude the side wall of the container, so that the volume of the container is reduced, and the freeze fracture of the quartz glass tube is avoided.

Description

technical field [0001] The invention relates to an electric water faucet. Background technique [0002] The electric hot water faucet is named after it can produce hot water within 3-5 seconds after it is turned on. The electric hot water faucet has the characteristics of low price, small size, and continuous heating. [0003] The heating device of the traditional electric faucet is a resistance wire. In order to increase the contact area between the resistance wire and the water, the resistance wire is generally wound into a spiral shape. When in use, scale is easy to deposit on the surface of the resistance wire. The main components of scale are calcium carbonate and magnesium hydroxide, and these two materials have poor thermal conductivity, which will form a layer of heat resistance, which will affect the resistance of the resistance wire. heating effect. Moreover, when the current passes through the spiral resistance wire, an induced magnetic field will be generated,...

Problems solved by technology

[0005] However, the quartz electrothermal film heating tube has high hardness but is very brittle. After the water in the tube freezes, the tube body will swell and crack due to volume expansion, so it is necessary to change it.
