Abstract
The utility model relates to a magnetic device for cleaning both sides of glass simultaneously, which belongs to the cleaning device for the window glass. The utility model is particularly a device used for cleaning the window glass of the high-rise building by the magnetic force. The utility model comprises an active device for cleaning glass and a passive device for cleaning glass, and the active device for cleaning glass and the passive device for cleaning glass are respectively arranged on the inner side and the outer side of the window glass. Each device for cleaning glass is mainly composed of an outer shell, a cleaning head, a water scraping head, a magnet, and an angular wheel or a movable bead. The magnetic force of the magnetic device for cleaning both sides of glass simultaneously of the utility model is great. The utility model which has simple structure, low cost, convenient use and safe operation is especially suitable for cleaning the window glass of the high-rise building and the outer wall of the glass.
Description
The utility model belongs to the cleaner of glass pane, particularly in the utensil with the magnetic force double-side window-cleaning.
At present, exist design with the double-side window-cleaning device of magnet suction and construct unreasonable, use dangerous or the like defective.Used magnetic force double-side window-cleaning device is by at the active magnet of glass pane inboard and relative being constituted by moving magnet in the glass pane outside, when two magnetic alignment, produce the magnetic line of force betwixt perpendicular to glass surface, make mutual adhesive, after inside and outside two blocks of magnet slightly have dislocation, still produce the magnetic line of force in its intersection perpendicular to glass, then produced the oblique magnetic line of force in the dislocation part, this oblique magnetic force can be decomposed into vertically and be parallel to two components of glass, the effect that is parallel to the magnetic force component of glass is initiatively to wipe the passive pulling force of wiping head of head pulling, also will overcome gravity simultaneously, this parallel magnetic force is the key of magnetic force window-cleaning device.
Only produce owing to become the oblique magnetic line of force, cry " edge effect " in the edge of bulk magnet.The pulling force that magnetic force produced that is parallel to glass need overcome passive the wipe frictional force of head and making a concerted effort and could normally using of gravity.The pulling force that produces greater than magnetic force if make a concerted effort is wiped head and will be fallen down.The passive wiping head of magnetic force window-cleaning device of the prior art directly contacts with glass, therefore coefficient of friction is very big, and under the certain condition of coefficient of friction, the intensity that increases magnet will increase frictional force, because of frictional force=normal pressure * coefficient of friction, can not solve problem safe in utilization like this.In sum, there are the following problems for prior art:
(1) owing to only adopt a pair of bulk magnet, the magnetic force component that is parallel to glass that produces in its " edge effect " is not enough, is difficult to overcome making a concerted effort of frictional resistance and gravity, and is in use dangerous;
(2) after a pair of big magnet produces " edge effect ", more perpendicular to the positive suction minimizing of glass, increased unsafe factor of using;
(3) passive wiping head all and glass contact, coefficient of friction is very big, the frictional force of generation is also very big, the required magnetic force component that is parallel to glass is just big especially, finally leads to the failure.
The purpose of this utility model will overcome shortcoming of the prior art exactly, proposes a kind of novel structure, magnetic force double-side window-cleaning device reasonable in design, and it is specially adapted to the windowpane of skyscraper.
In order to realize the purpose of this utility model, reduce unnecessary coefficient of friction (referring to passive wiping head), increase the edge effect of magnet, make it can produce enough magnetic force component that is parallel to glass.
The concrete structure of magnetic force double-side window-cleaning device of the present utility model is:
(1) on passive wiping head, horn ring or movable pearl are installed, make passive invalid part (support magnet segment) of wiping head directly not contact glass,, thereby reduced the required magnetic force component that is parallel to glass with reduction frictional force;
(2) the big magnet of monolithic is become polylith magnet more than two, and be combined in bulk magnet and fritter magnet respectively, the effect of bulk magnet is to produce enough the suction-combining forces, and the effect of fritter magnet is to produce enough magnetic force component that is parallel to glass;
(3) adopt quick change to wipe the structure of head.
In order to further specify magnetic force double-side window-cleaning device of the present utility model, specifically describe in conjunction with the embodiments with reference to accompanying drawing.
Embodiment one: dual-magnetic head two-sided magnetic window-cleaning device
As shown in Figure 1, in the drawings: 1 is shell, and 2 is horn ring or movable pearl, 3
1Be big magnet, 4 is scrub head, is water wiping head.
Horn ring or movable pearl 2 are propped shell, make it directly not contact glass, and to reduce frictional force, two blocks of magnet produce enough edge effects, spur passive scrub head 4 or/and water wiping head 5 etc. must produce enough the suction-combining forces simultaneously.Shell 1 adopts aluminium alloy plate or plastic injection-moulded forming, and in light weight, simple in structure, cost is low, and it can be equipped with various cleaning heads, is fit to general family and uses.
Embodiment two: many magnet double-side window-cleaning device
As shown in Figure 2, small magnet 3 wherein
2Profile can be different shape such as circular, square, fritter magnet 3
2In use all can produce edge effect basically, can produce bigger pulling force, motion in use freely.Simultaneously, adopt the little permanent strong magnet of polylith to replace bulk magnet, cost is low, and the suction-combining force is big, and is safe and reliable.
Embodiment three: strong magnetic force double-side window-cleaning device
As shown in Figure 3,3 is bulk magnet among the figure, and 4 is fritter magnet, and 7 is active window-cleaning device (in the window inboard).
Magnetic force is very strong, the bulk magnet core remains the magnetic force perpendicular to glass in the use, fritter magnet all is oblique magnetic lines of force basically, thereby the suction-combining force is very big, the magnetic force component that is parallel to glass is also very big, guarantee easy to use, safety operation, it is applicable to heavy sheet glass such as the large windows of public places such as hotel and glass outer wall.
Embodiment four: the magnetic-type double-side window-cleaning device is covered in activity
Shown in Fig. 4 (a) and (b), 3
3Replace fritter magnet 3
2, U type magnet 3 when not using
3Be unified into annular, shown in Fig. 4 (a), most of magnetic line of force all in loop, is beneficial to deposit.During use, U magnet is rotated 90 ° get final product, shown in Fig. 4 (b), wherein the quantity of U magnet can be one or more pairs of.
Embodiment five: fixedly cover the magnetic-type double-side window-cleaning device
Shown in Fig. 5 (a) and (b), basic identical with embodiment four, be U magnet 3
3Be fixedly the time, can clean the windows to lumping together inside and outside when depositing, excessive with the demagnetize line of force.
