Steam cleaning machine

Abstract

The invention discloses a steam cleaning machine which comprises a cleaning brush head for cleaning a surface to be cleaned, a handle assembly arranged at the upper portion of the cleaning brush head and a steam supplying mechanism for supplying steam to the cleaning brush head. The steam supplying mechanism comprises a water tank arranged in the handle assembly, a heater arranged in the cleaning brush head and a water feeding controller connected between a water outlet of the water tank and a water inlet of the heater. The water feeding controller is provided with a water injection port communicated with the inside of the water tank and a water collecting cavity, wherein the water collecting cavity is communicated with the inside of the heater, an air inlet hole communicated with outside air is arranged on the wall of the water collecting cavity, and the opening position of the air inlet hole is higher than that of the water injection port. The water feeding controller capable of automatically feeding water into the heater is arranged between the reversed water tank and the heater and can automatically feed the water into the heater without manual control, so that accidental conditions such as heating without water or overfilling can be avoided, the safety performance is high, and cleaning efficiency and quality are improved.

Description

technical field [0001] The invention relates to a steam cleaning machine. Background technique [0002] At present, the steam mop in the market is composed of a water tank, a pump (manual pump or electromagnetic pump), and a heating body. The water in the water tank is drawn into the heater by the pump for heating, and the switch or valve controls the pump to generate steam to treat the cleaning surface. Clean up. Such as choosing a manual pump (such as the technical solution of the steam floor brush with patent number 200680051301.0): although the price is moderate, it is quite cumbersome to use, and it cannot control the water volume in the heating body in real time and accurately, which may easily lead to dry burning or full heating. If the electromagnetic pump is used, it is easy to operate but expensive, and it also has many parts and complex structure, and the enclosure and maintenance are cumbersome; if the pump structure is not used (depending on The gravity of the...

Problems solved by technology

Such as choosing a manual pump (such as the technical solution of the steam floor brush with patent number 200680051301.0): although the price is moderate, it is quite cumbersome to use, and it cannot control the water volume in the heating body in real time and accurately, which may easily lead to dry burning or full heating. If the electromagnetic pump is used, it is easy to operate but expensive, and it also has many parts and complex structure, and the enclosure and maintenance are cumbersome; if the pump structure is not used (depending on The gravity of the water itself flows into the heating body): It is easy to operate, but there will be a problem that the water level in the water tank will continue to decrease, and the flow rate will continue to slow down, and the generated steam will also be unstable, which will affect the use effect
