Description

Hand-held steam cleaner Technical Field The utility model relates to the technical field of products for cleaning electric appliances, in particular to a handheld steam cleaner. Background The steam cleaner is a cleaning tool with a sterilizing function, dissolves stubborn dirt attached to an object by using 100-DEG C high-temperature steam, does not use any chemical substance, cleans and sterilizes by using a small amount of tap water, saves water and electricity, and is a healthy and environment-friendly household product. The steam cleaner is suitable for solid wood floors, composite floors, ceramic tiles, marble, glass plates, foam pads and the like. The working principle of the steam cleaner is that the movement speed of molecules on the dirt surface is accelerated by the steam generated at high temperature, the aim of eliminating various stubborn stains is fulfilled by destroying the binding force between the molecules, and clear water can be quickly converted into high-temperature and high-pressure strong steam within 30 seconds by using a special steam generating system with a water pump. While various bacteria, mites, microorganisms and pathogens attached to the object are completely eliminated. With the fittings such as nozzles, brushes and the like with various convenient functions, the environment-friendly concept of any chemical reagent is not needed, and the high efficiency of quick decontamination and sterilization is realized. The detergent is widely used for sterilization, dust removal, decontamination, oil removal and peculiar smell removal, and is suitable for units and families. The steam cleaner has unique cleaning effect, is a good product for modern cleaning, is provided with a plurality of accessories with different functions and different purposes, can remove bacteria, microorganisms and tiny impurities by means of the powerful deoiling cleaning power of steam, can be directly used for daily cleaning of floors, and can thoroughly clean door and window glass, mirrors, sofas, floors, toilet appliances and a plurality of corners which are difficult to clean every day. Can clean kitchen utensils such as gas cookers, range hoods and the like, can iron clothes, and is a good assistant for housewives. The handheld steam cleaner is a steam cleaner, has small size, is convenient to carry and easy to hold and move, and is favored by wide users. In the prior art, referring to patent document CN221533608U, a dual-mode hand-held steamer is disclosed, which comprises a hand-held steamer body, a steam boiler, a power base and a locking mechanism, wherein a steam generating cavity is arranged in the hand-held steamer body, a water inlet and a steam outlet are formed in the hand-held steamer body, the steam boiler is arranged in the steam generating cavity and is respectively communicated with the water inlet and the steam outlet, the power base can be electrically connected with the steam boiler through an electrical connection structure, and the locking mechanism is arranged between the hand-held steamer body and the power base and at least has a locking state and an unlocking state. In the locked state, the invention generally aims at cleaning the heavy oil pollution area, and the steam boiler needs to be kept running for a long time to provide a large amount of cleaning steam, in the unlocked state, the invention generally aims at cleaning the light oil pollution area, and the main body of the hand-held steam engine is separated from the power base for independent use, so that the invention has better operation flexibility, is lighter and causes smaller pressure to users. The internal structure shown in the above patent document is the scheme of most hand-held steam engine on the market, and has certain defects, for example, 1, all adopt the submerged boiler inner container, steam generated after the boiler inner container is heated needs to flow upwards and then be sprayed out from the steam outlet nozzle, the self-flow of the steam is not restrained, so that partial steam is liquefied after hitting the inner wall, the steam output is reduced, high-temperature liquid water is mixed when the steam is generated, the safety and the using effect are affected, 2, the switch structure adopts a pure physical blocking structure, and the switch structure mainly acts on a pipeline between the boiler inner container and the steam outlet nozzle in the prior art, so that no matter whether a user needs to continuously output the steam, once the boiler inner container is started, the boiler inner container can continuously heat and generate the steam, firstly, the steam is continuously generated, secondly, the pressure in the boiler inner container is higher and higher when the switch structure is closed, a certain potential safety hazard exists, 3, the water tank and the boiler inner container are of an integral structure, and therefore, all the water in the boiler inner container needs to be heated each tim
