Description

Hard surface cleaner with sewage recycling

Technical field

The present invention relates to a cleaner, and more particularly to a hard surface cleaner with sewage recycling.

Background technique

When cleaning hard surfaces such as walls, glass and floors, it is difficult to completely remove the dust and water film on the surface by wiping, and the cleaning effect is not good. To this end, various water-absorbent cleaners have been invented to clean hard surfaces, the main principle of which is to generate a suction air flow by means of a suction unit, so that dust and small water droplets can be sucked from the hard surface through the suction nozzle, and Transfer dust and water droplets to the dirty liquid tank. A hard surface suction apparatus, as disclosed in U.S. Patent No. 6,347,428, which produces suction flow by a suction unit, is guided through a suction port of a suction nozzle or a rotor that drives a brush through a transmission. The suction airflow from the suction port of the suction nozzle passes through the dirty liquid tank, wherein the small droplets are separated from the liquid air mixture inside the dirty liquid tank. A water-absorbent cleaner disclosed in Chinese Utility Model Patent Publication No. CN202843507U (Patent No. ZL201220452180.3), the water-absorbent cleaner comprising a casing, and a suction nozzle is mounted on the top of the casing. A separation chamber located above and an accommodation chamber located below are formed inside the casing, and the separation chamber is electrically provided with a separation head, and a suction device and a dirty liquid tank are disposed in the accommodation chamber. In operation, the gas-liquid mixture is sucked from the suction nozzle to the separation chamber, and the suction device generates a suction air flow. After the gas-liquid mixture is separated by the separation head, the air is sucked into the suction device, and the liquid flows into the dirty liquid tank. The above two types of cleaners often need to be used in conjunction with another watering can during use. When using, the user often holds the watering can with one hand, the other hand holds the cleaner, or the right hand alternately holds the watering can and the cleaner. First, spray the water on the hard surface to be cleaned with a watering can, and then use the cleaner to spray the water area. Cleaning the hard surface is not only very inconvenient, but also the water that is sucked into the dirty liquid tank cannot be recycled.

In the prior art, there is also a hard surface cleaner using two liquid storage cartridges, such as the water-absorbent cleaner with water spray function disclosed in Chinese Patent Application Publication No. CN102920398A (Application No. 201210440941.8), The cleaner is detachably coupled to the container under the housing, the container including a separate first portion and a second portion, the first portion having only a water flow passage inserted into the housing and a portion communicating with the water flow passage below the water flow passage

In the water storage tank, a second water storage tank is formed in the second part, and the water in the second water storage tank can be sprayed out of the casing through the liquid spraying device. The first water storage tank and the second water storage tank of the cleaner are independent of each other, and the sewage separated by gas-liquid separation enters the first water storage tank through the water flow passage, and the clean water or the clean water mixed with the cleaning agent is pre-filled in the second water storage tank. It can be seen that although the cleaner has the functions of water spraying and cleaning, it does not have to be used together with another watering can in the cleaning process, but it also has the following defects: since two liquid storage tanks are arranged in a limited cleaner space, It is bound to make the volume of each storage tank relatively small. During the cleaning process, the dirty water in the first storage tank will be more and more, and the clear water in the second storage tank will be less and less, so complete one time. A large area of hard surface cleaning often requires multiple injections of clean water into the second storage tank and the sewage in the first storage tank is poured out several times, which is not only inconvenient to operate, but also consumes a large amount of water during the cleaning process.

Summary of the invention

The technical problem to be solved by the present invention is to provide a hard surface cleaner with sewage recycling, which is convenient to use and has a small water consumption during the cleaning process, in view of the above-mentioned state of the art.

Of course, in the solution of installing the filter head in the liquid inlet of the liquid take-up pipe, the liquid inlet end of the liquid take-up pipe can be kept at the low position of the liquid storage container due to the weight of the filter head itself, so that no additional installation is required. Said liquid ball.
