Hand-held equipment with cleaning, air-drying and spraying function

Abstract

The invention discloses hand-held equipment with a cleaning, air-drying and spraying function. The hand-held equipment with the cleaning, air-drying and spraying function comprises a cleaning head, acleaner main body, a liquid storage tank and a handle; a Venturi tube and an air feeding assembly are arranged in the cleaner main body in sequence; the middle part of the Venturi tube is a negative pressure tube section used for sucking water; the front end of the Venturi tube is a shrinking part with tube diameter of larger than the negative pressure tube diameter; the rear end of the Venturi tube is an expanded tube section with tube diameter of larger than the negative pressure tube diameter; the front port of the shrinking part and the cleaning head form a spraying outlet or an air-dryingoutlet; at least one water pipe communicating the cavity of the negative tube section is arranged on the wall of the negative pressure tube section; the water pipe is connected with a water inlet pipe; the rear port of the expanded tube section is connected with an air feeding opening of the air feeding assembly; a motor of the air feeding assembly is electrically connected with a battery on thehandle; and the water inlet pipe passes through the handle and extends out of the handle to communicate with the water storage tank. According to the hand-held equipment with the cleaning, air-dryingand spraying function, through adoption of the external water storage tank, the Venturi tube and the air feeding assembly, gas-liquid spraying and wind power are formed through a Venturi effect to realize a cleaning, air-drying and spraying effect on objects.

Description

technical field [0001] The invention relates to the technical field of hand-held devices, in particular to a hand-held device with cleaning, air-drying and spraying functions. Background technique [0002] At present, most of the known handheld devices have a single function. For example, cleaner technology generally adopts the three-in-one mode of water storage, water pump, and spray washing. The only difference is in the structure of water storage and spray washing. , the existing cleaners are all designed for a single place, such as cleaning wooden floors, tile surfaces, glass surfaces, exterior walls or washing cars. Multiple cleaners not only require a large expenditure, but also store these devices at the same time. The larger space is detrimental to the appearance; and the household car washers currently on the market are generally divided into two types, one is a portable car washer, which uses manual or foot pumping to generate high pressure in the pot, and then thr...

Problems solved by technology

The above two household car washers have the advantages of small size, compact structure, and easy to carry, etc., but they consume a lot of water when washing the car and the sewage is directly discharged without recycling, which wastes water resources. Electric car washers need to be connected to power and water sources at the same time , more troublesome, you need to go to a special place for car washing, and you can't wash your car anytime and anywhere. Both the cleaner and the car washer have the disadvantage of single function. The current cleaner or car washer can only be done by the cleaning head or the water spray head. Cleaning, and after cleaning, especially when cleaning tiles, glass or cars, it is necessary to use other drying tools, such as towels, to dry the cleaned objects or blow them with a fan, which is inefficient and cumbersome. Especially for large physical surfaces, it takes a lot of time to dry manually with a towel
