The working principle of an installation-free portable instant hot pure water machine with a washable filter element: manually add water to the raw water tank, connect the power supply, and the raw water passes through the filter cloth bag in the raw water tank to remove the visible impurities larger than 5 microns in the water. Such as suspended solids, sediment, rust, etc., after the first filtration, the water passes through the self-priming booster pump, which has a strong self-priming function, and flows through the composite filter element to remove impurities such as suspended solids larger than 1 micron At the same time, it can effectively absorb substances such as color and odor in water, residual chlorine in water, etc. Under high pressure, water passes through RO reverse osmosis membrane, and the purified water produced is sterilized by a sterilizing device and stored in a pure water tank; pure water The water level float in the tank senses and controls the water production work; the concentrated water discharged from the RO reverse osmosis membrane returns to the bottom of the original water tank through the flushing valve; the user performs the water intake operation through the unlock/temperature adjustment/water intake rotary integrated key; the water intake is normal temperature water And hot water, when taking normal temperature water, directly press the one button, the purified water in the pure water tank will pass through the water pump and then flow through the heating device. At this time, the heating device will not heat, then flow through the water vapor separation box, and finally separate Pure water at normal temperature flows out of the water outlet of the box; when hot water is needed, select hot water of different temperatures through the rotary integrated button, after selecting the temperature, press the rotary integrated button, the purified water in the pure water tank passes through the pump and flows through the The heating device performs heating work at the same time, passes through the water vapor separation box, and finally flows out the selected hot water from the water outlet of the water vapor separation box; the traditional heating device is directly connected to tap water, and there will be serious scale in places with poor water quality, which will affect the use of heating However, since this machine heats the pure water in the pure water tank, it avoids the generation of scale and can be used for a longer period of time; traditional heating repeatedly burns, which is a waste of electricity, while this machine only heats when water is taken, which saves more power. More energy-saving; it is very convenient for users to fetch water.

The composite filter element, RO reverse osmosis membrane, and sterilizing device all have automatic identification functions. At the installation position, each level corresponds to a group of reed switches for sensing signals, which are embedded with permanent magnets. When installed in place, the signal is closed, and the water purifier Automatically identify and work normally; when there is no installation or the installation is not in place, the signal cannot be sensed, and the pure water machine will automatically stop working and prompt the user to install abnormally. At present, there is basically no identification function in the market. It can still be used when the machine is not installed in place. work, resulting in serious water leakage; this system solves the problem of automatic identification of whether the installation is in place; at the same time, the user uses a special filter element to prevent water leakage or poor water filtration effect caused by the use of bad filter elements.

When the accumulation of impurities increases during use, the filter bag in the filter cloth bag can be directly removed, and the filter bag can be washed repeatedly to clean the attached impurities. That is, the service life of the pre-filter element, which solves the problem that the pre-stage of conventional pure water machines is easy to block and cannot be cleaned in places with poor water quality; it solves the problem that users who use well water as their water source in rural areas need dealers to frequently send after-sales service personnel to visit Service to replace the filter element, which saves money and is environmentally friendly.

An installation-free portable instant hot water purifier with a washable filter element in this embodiment is easy to assemble, the user does not need to install the machine, it is ready to use after plugging in, and it is convenient to take water; avoiding secondary pollution of pure water, At the same time, the concentrated water automatically detects the cycle and prompts for water shortage, achieving the effect of environmental protection and saving water resources; and the filter bag can be cleaned and reused by users, which solves the problem that the users who use well water as the water source in rural areas need dealers to frequently send after-sales service personnel to provide door-to-door service Replace the filter element problem, which saves money and is environmentally friendly.
