Description

A double-sided window cleaner with a mechanical scrubbing head

technical field

The invention relates to household appliances, in particular to a double-sided window cleaner with a mechanical scrubbing head.

Background technique

There have always been two problems in scrubbing the windows of the home, one is the inconvenience of scrubbing the high windows, and the other is the inconvenience of scrubbing the outside of the windows. These two problems have always been a headache for housewives and cleaners. Aiming at these two problems, the basic content of this project research is to design a household window cleaner that can clean the inner and outer windows at the same time and solve the problem of high-level scrubbing, and take the current numerous aluminum alloy sliding windows as the design environment.

This project intends to integrate the market research of existing products and the needs of users, so that the designed new type of window cleaner can not only realize the cleaning of the inside and outside of the window, but also prevent users from climbing.

Through a large amount of market investigations at home and abroad, there are many types of instruments that can alleviate manual window scrubbing. The above-mentioned two aspects of the problem have been solved respectively at present, but the product that can meet the above-mentioned two aspects of requirements has not been found so far. For example, for the former, there are many types of telescopic rod scrubbing tools on the market, which can achieve the effect of lengthening people's arms and avoiding climbing. However, after investigation, there are still problems such as insufficient scrubbing power for high places and dead spots for scrubbing. , and none of them can realize the scrubbing of the outside of the window; for the second problem, that is, the cleaning of the outside window, at present, domestic window cleaning devices for cleaning the outside glass of the window have been put into the market, and the most typical one is the powerful magnetic double-sided window cleaner , both cheap and fine manual devices, as well as the latest intelligent automatic window cleaners with a price of more than 3,000 yuan. Both devices are designed around the mutual attraction of magnets. These window cleaners consist of two identical scrubbing heads with opposite magnets mounted on each. Its working principle is that two scrubbing heads must be manually adsorbed on both sides of the glass before scrubbing. When scrubbing, the scrubbing head on the inner glass is moved, and the outer scrubbing head is driven by magnetic force to move at the same time, so as to achieve the inner and outer sides of the glass. cleaning. This device has undoubtedly brought revolutionary progress for the scrubbing of inside and outside windows, but also has many deficiencies. First of all, it still has not solved the problem of scrubbing at high places, (although intelligent window cleaners can solve the problem of scrubbing at high places, if one piece of glass needs to be changed to another glass after being wiped, it must still be replaced manually, and due to the magnetic force It is very large, and it is more laborious to replace). Secondly, during the scrubbing process, the active scrubbing head on the inner side of the window should not move too fast, otherwise, the outer scrubbing head will easily fall off; at the same time, in order to make the magnetic force strong enough, the magnet volume will also be large, resulting in a large increase in the weight of the scrubbing head . In addition, because there are many types of glass and different thicknesses, it also brings many difficulties to this kind of window cleaner. Some glass is tempered glass, and some glass is vacuum in the middle, which will make the magnetic force between the two scrubbing heads become smaller, causing the outer scrub head to fall off.

At present, there are no such products in the domestic market for mechanical double-sided window cleaners, and the double-sided window cleaners only have the magnetic suction type.
