Abstract

The utility model relates to an applied magnetic double-sided window wiper, comprising a permanent magnet, a scraping plate, a cover plate, etc. The key point is that at least two magnets with the same polarity connected with a magnet with an opposite polarity are arranged on a magnetic conductive plate, forming a magnetic composite body provided with an open circuit magnetic circuit. Thereby, an inner wiper and an outer wiper can move optionally and synchronously on thick glass. At least two such magnetic composite bodies are distributed in an isolated mode on the wiping surface of each wiper. The synchronous plane rotation of the inner wiper and the outer wiper is ensured. Thereby, the utility model has the advantages of safety, practicability, and non-falling off.

Description

Magnetic device suitable for cleaning window both sides simultaneously

The utility model is a kind of cleaning glass instrument, and it is two-sided especially to be convenient to the while cleaning glass.

Increasing along with glass of building, especially the increase greatly of skyscraper glass, people are to also urgent day by day in the two-sided instrument demand of indoor security cleaning glass, in recent years, to how solving two-sided wiping window problem, researchers have proposed many designs, wipe in the window design at magnetic force, multiple design has also appearred, but take a broad view of numerous magnetic force and wipe the window scheme, conclude and get up to have only two basic structures: the one, the suction type structure, be that one or more magnets are distributed in wiping face with monomer, as Chinese utility model patent 89217348.3,90203577.0, this structure can only the relative magnet suction of inner outer rub body produces and is synchronized with the movement, and interior wiping moves that outer the wiping easily comes off when too fast.Another kind is a push-pull structure, promptly press heteropole and link to each other arranged distribution on wiping face with magnet, as Chinese utility model patent 89209005.7, though can pushing away a pulling force by one, this structure make inside and outside rub body produce same moved further in the face of wiping all directions, but because the push-and-pull arm of force is very short, being close to does not have push-and-pull moment, thereby when interior rub body rotates, the rotating torque that outer rub body is not driven, and be easy to come off.Because two-sided wiping window is generally manually-operated, operating process is often moved and is rotated and all will take place, thereby the magnetic force window cleaner of said structure still feels undesirable.

It is inside and outside arbitrarily mobile synchronously that the utility model aims to provide a kind of rub body that can guarantee, can make rub body arbitrarily rotate adeciduate suitable type magnetic double-face window cleaner along the face of wiping any direction again.

The utility model is to realize like this, at first with three or more the polylith permanent magnet place on the magnetic conduction sheet and to form the magnetic assembly, the structure of this magnetic assembly is: wherein magnet with the magnetic conduction sheet contact-making surface on be a certain polarity, these all magnets of piece magnet and all the other all link to each other, and all the other magnets all are another polarity opposite with this magnet, can locally link to each other and can also not connect between all the other magnets.

When rub body moves as the plane at the window face, it is two-dimensional space, only when two-dimensional directional all has locomotivity, inside and outside rub body could be made the same moved further of any direction at the window face, generally speaking, and under at least three permanent magnets interact, the angle difference as long as magnet links to each other, two magnetic assemblys of Xiing all can produce the locomotivity except that suction of two-dimensional directional mutually, and like this, every pair of the inside and outside rub body magnetic assembly of inhaling mutually all can produce and drive the other side's rub body along the locomotivity of any direction.Simultaneously, permanent magnet with two or how same polarity links to each other with another magnet of opposite polarity, because the effect of magnetic conduction sheet is arranged, thereby has a magnet of opposite polarity, link to each other or single magnet is placed and will be produced bigger magnetic flux than its magnet with another polarity of monolithic, thereby wiping on the window, showing as locomotivity and suction is all strengthened, producing stronger effect.

When rotating for rub body in guaranteeing, it is synchronous with interior rub body that outer rub body can be subjected to a driving torque, and another characteristics of the present utility model are: on one side wiping board, spaced at least have two magnetic assemblys.Because each magnetic assembly all has the locomotivity of any direction, thus no matter rub body in the face of wiping upper edge where to rotation, with on the wiping board on one side, all can produce a moment of torsion between two magnetic assemblys, so that interior rub body drives outer rub body rotation.For guaranteeing that torsional forces can enough drive outer rub body, the utility model regulation: be not less than half of the minor face of wiping board at least with the partition distance of two the magnetic assemblys farthest of being separated by on the wiping face of one side.

Concrete structure of the present utility model is provided by following examples and accompanying drawing.

Fig. 1 is entire combination signal and the partial sectional view of the utility model embodiment.

Fig. 2 is wiping board wiper plane and the magnetic assembly distribution schematic diagram of the utility model embodiment.

According to the embodiment accompanying drawing basic structure of the present utility model and working condition are described below.

As shown in Figure 1, suitable type magnetic double-face window cleaner described in the utility model is by permanent magnet (1), cover plate (2), wiping board (3), magnetic conduction sheet (6), wipes inside and outside two rub bodies of window thing (5), safety rope (4), handle (7), extension bar parts such as (8) formation.

In Fig. 1, being connected together by permanent magnet (1) and magnetic conduction sheet (6) constitutes the magnetic assembly and is fixed in the wiping board (3), and wiping board (3) can be a through hole with the connecting hole of magnetic assembly, can also be groove; The distribution of magnetic assembly, as shown in Figure 2, on one side wiping board, spaced at least have two, and in each magnetic assembly, one of them magnet is a certain polarity, and other magnet is the polarity opposite with it.Cover plate (2) covers on wiping board (3), and is can be with wiping board integrated or separate, and wipes window thing (5) and wraps in or be embedded on the wiping face of wiping board (3) or cover plate (2), is used for directly contacting glass (9) and carries out wiping; Handle (7) and extension bar (8) are respectively applied for wipes lower and eminence glass, and safety rope (4) comes off bad for preventing people's outer wiping when unpluging inside and outside the wiping.

Wiping process is comparatively convenient and simple, can be in the window open place, with outer rub body send outside window with interior rub body can random wiping to inhaling, to the small amount of dust window is only arranged, xerotripsis can be taked,, cleaning agent can be added in wiping the xerotripsis of alternately wetting on the window thing to greasy dirt or dirtier glass are arranged.

Double-face window cleaner described in the utility model, wiping board and cover plate are by the lightweight of wear and shock-resistant not magnetic conductive metal or nonmetal making, wipe the window thing and is made up of one or more of gentle materials such as wiper, sponge or rubber, handle and extension bar are made with the metal or the nonmetallic materials of threading firmly.

The utility model has been owing to guaranteed the synchronous plane motion of inside and outside rub body and rotated, thereby realized two-sided wiping window safe, practicality, do not come off.
