Description

Hand push fuel steam cleaning machine

【Technical field】

The invention relates to a hand-push fuel steam cleaning machine, which may be a steam cleaning machine using diesel combustion and heating.

【Background technique】

At present, water resources are scarce. When cleaning the kitchen or other daily necessities and furniture at home, in addition to wiping with a large amount of water or detergent, some oily dirt must be washed with hot water to achieve a better cleaning effect. When using hot water to clean, it is necessary to put hot water in a basin container and then pour it on the object to be cleaned for cleaning and wiping. If it is in such a container, the temperature will drop rapidly, which may lose its cleaning effect and waste a lot of water resources. So someone invented a steam cleaning machine for cleaning articles with steam, but the current commercially available steam cleaning machines are all directly connected with a conduit on the heating container, and the steam in it is exported and sprayed to the surface of the article to be cleaned and wiped, so as to To improve the effect of removing oil and dirt, but the general steam only shows the pressure without controlling the pressure. Due to human negligence, there is a danger of explosion due to excessive pressure. In addition, when the general steam cleaner wants to pause for a while or stop using it, it will The temperature of the water in it is still in an extremely boiling state. Even if the power is turned off, the steam will continue to be sprayed out for a period of time until the temperature and pressure in the heating container decrease. When you want to temporarily stop the cleaning work of the steam cleaning machine in case of temporary incidents, the steam cannot be stopped in time, or even the steam cannot be controlled in time when the steam is stopped, so that the continuous steam will form a large number of water droplets and wet the floor or carpet in the house. , still can not save water resources, therefore, in order to solve the problems of traditional steam cleaning machine in complex structure, low heating efficiency and inconvenient use, we have developed a hand-push fuel steam cleaning machine.
