Tubular steam generator and wireless steam mop

Abstract

The invention discloses a tubular steam generator and a wireless steam mop, and relates to the field of household floor cleaning devices. The tubular steam generator comprises a screw rod, a metal pipe which is arranged outside the screw rod in a sleeving mode and forms a spiral flow channel with threads of the screw rod,a water inlet and a steam outlet which are formed in the two ends of the metal pipe respectively, and a water outlet preventing mechanism which prevents water from flowing out of the steam outlet, a high-temperature-resistant insulating layer is arranged on the outer wall, corresponding to the spiral flow channel, of the metal pipe, and a graphene heating layer is arranged on the insulating layer. The wireless steam mop comprises the tubular steam generator. The tubular steam generator is convenient to manufacture, and can output steam in real time on the premise of avoiding water leakage of the steam outlet in the starting stage of the steam generator and avoiding dry burning of the electric heating element.

Description

technical field [0001] The invention relates to the field of household floor cleaning devices, in particular to a tubular steam generator and a wireless steam mop using the tubular steam generator. Background technique [0002] The steam mop can spray steam on the cleaning surface, so it has the effect of disinfecting the cleaning surface, and can effectively remove stubborn stains that cannot be removed by ordinary water. [0003] However, the process of turning water into steam needs to consume a large amount of electric energy and wait for a long time, which seriously restricts the popularization and application of steam mops, especially wireless steam mops. , the steam mop that does not need to be connected to the mains during work. For this reason, people are studying to add a small steam generator, supply water to the small steam generator through the clear water container on the mop, utilize the small steam generator to convert water into steam in real time, reduce t...

AI Technical Summary

Problems solved by technology

This type of small-sized steam generator still has the following technical defects: one, the life-span of its electric heating plate is short, and it is easy to break; Water will be sprayed out for a short time, that is, there is a phenomenon of water leakage from the steam outlet; 3. The internal heating box structure is generally adopted, and the above-mentioned ceramic heating sheet is arranged in the box body. During manufacture, a water tank needs to be formed on the inner wall of the box, and it needs to pass through Electrodes are drawn from the box wall, so the manufacturing process is more complicated

This solution effectively solves the above-mentioned technical defect 2, but brings new technical problems, that is, the electric heating sheet will be dry-burned every time it is started, which will seriously affect the service life of the steam generator
