DETAILED DESCRIPTION OF THE PRESENT INVENTION

(9) Design example of the car washer product based on the present invention: as shown in FIG. 1, the product is mainly formed by a soft water bag (1), a manual change valve (2), a cover plate outer box with castors, an automatic take-up reel (6), an electric water pump, a water pipe (5) and a water gun. The soft water bag is made of a soft material and is foldable. The water bag is fully sealed in work and can be placed in the outer box after all water is discharged from the water bag.

(10) Wherein the appearance of the cover plate outer box with castors is the same as that of a suitcase and is characterized in that four castors are mounted below the cover plate (4), and the cover plate (4) can be completely taken off, is cushioned under the box body (3) after being taken off and fixed via hooks. Thus, the cover plate outer box with castors becomes a trolley in use and becomes a suitcase in storage, so that portability is greatly increased.

(11) Wherein the wire in the automatic take-up reel (6) must be long enough to surround the car by half a circle. Before use, the wire can be completely pulled out easily, and then the plug is inserted into a car cigarette lighter. After use, the wire can be automatically retracted via an elastic mechanism in the reel by pressing a button.

(12) The water way connection of the change valve is shown in FIG. 2 or FIG. 3. The two-position five-pass manual valve in the figure has five water openings R, A, P, B and S, R and S are connected with the water bag, P is connected with the water gun, and A and B are respectively connected with the water feeding and discharging openings of the water pump.

(13) For the work of the water way shown in FIG. 4, 203 in the figure is the two-position five-pass manual valve, and the opening R is blocked; during parallel connection, water flows in two separate ways from the feeding opening (201):

(14) First way: Water is pumped to the change valve (203) via the pump 1 (204), and the opening B of the valve is communicated with the opening S to flow to the discharging opening (202);

(15) Second way: Water flows to the change valve (203), the opening A of the valve is communicated with the opening P, and water is pumped to the discharging opening (202) via the pump 2 (205).

(16) Water flow in series connection: At the moment, the opening B of the change valve (203) is communicated with the opening P, the opening A of the valve is communicated with the opening R, and the opening S is communicated with the discharging opening (202). Obviously, the water pipes communicated with the opening A and the opening S are not passages.

(17) Water is pumped to the change valve (203) from the feeding opening (201) by the pump 1, and after passing through the opening B and the opening P, water is pumped to the discharging opening (202) by the pump 2 (205).

(18) FIG. 4 is combined with FIG. 1 to obtain FIG. 5. In the figure, 301 is the upper water feeding opening of the water bag, 302 is the lower water discharging opening, and both of them are connected to the two-position five-pass change valve (303). The switching of the change valve makes the water discharging pipe connected to the water gun 300 fill water into the upper water feeding opening 301 under the pumping of the enhanced water pump or draw water from the lower water feeding opening 302.

(19) In FIG. 6, 400 is the soft water bag, 401 is the hinged door panel, its rotating shaft 402 is located below the outer edge of the box body side wall 404, and the hinged door panel turns upwards to rest against the side wall to perform the function of supporting the water bag. 403 is the adhesion part between the outer surface of the water bag and the hinged door panel. When the water bag is empty and retracted, the adhesion part 403 pulls the hinged door panel 401 to be closed. The longitudinal section of the box body is inverted trapezoidal, which is convenient for storage and transportation of the box body during production.

(20) 405 at the bottom of the figure is an upper cover of the outer box. From the sectional view, it can be seen that the appearance of the upper cover is convex just like a tray, and the concave surface is just attached to the bottom surface of the box body to support the box body. The concave surface and the box body are not fixed by using hanging buckles, but are attracted by using a magnet. The upper cover and the bottom of the box body are preferably provided with water drainage holes. 406 mounted below the upper cover are castors. The number of the castors is usually four, wherein the two front castors should be steerable castors capable of steering on a horizontal plane, and the two rear castors are non-steerable castors. In this way, the castors are flexible and convenient to use.

(21) For the water bag shown in FIG. 7, wherein 501 is the upper water feeding opening, and 502 is the lower water discharging opening. The inner surface of the water bag should be provided with a circle of bulges such as floating points, lumps and teeth surrounding the water discharging opening in the position of the lower water discharging opening. The action can prevent two surfaces from being attracted to block the water discharging opening when the water bag will be collapsed. 503 is the sponge fixed above the inside of the water bag and is used for absorbing remaining water as priming water for next water pumping. 504 is an openable opening cover and is mainly used for facilitating the cleaning and curing of the water bag, which is not necessary.

(22) FIG. 8 shows the appearance of the enhanced car washer. In the figure: the rotating shaft 402 of the hinged door panel 401 is located below the outer edge of the box body side wall 404, and the hinged door panel 401 rests against the box body side wall 404 to support the soft water bag 400 filled with water. 6014 on the front control panel is a main pulling handle of the change valve, which links the two manual change valves to work simultaneously, so that dual pumps are connected in parallel to increase the water quantity during water pumping, while the dual pumps are connected in series to increase the water pressure during spraying.

(23) A battery is installed inside the car washer, and 6012 is a power switch; 6013 is the water discharging opening of the car washer and is connected with the water discharging pipe 603 via a quick connector. The water discharging pipe is also provided with a power connection plug 6010 used for being inserted into a power connection socket hole 6011 to supply power to the lamp 3001 on the water gun 300, and 601 at the other end of the water discharging pipe is an electric plug used for connecting the lamp 3001; 602 is a water pipe quick connector and is used for connecting the water gun 300. 405 is the upper cover of the outer box and is cushioned under the box body, and the upper cover and the box body are mutually attracted via a magnet 407. 406 are castors with steering function.

(24) The car washer in FIG. 8 also has the following dimension and scale features:

(25) 1. The wheelbase of the front and the rear castors of the upper cover 405 is greater than or equal to the width of the upper cover, which is convenient for crossing and stacking of the upper cover in warehousing and transportation;

(26) 2. Castors can be placed in the box body when the upper cover 405 covers the outer box. The upper cover is the largest surface out of six surfaces of the outer box so that a long wheelbase and a wide tread can be created to stabilize the bearing water bag; and if the upper cover is designed to cover the box body, four castors are located outside the box body in a shape of holding the box body. It is considered that castors can be placed in the box body in such design;

(27) 3. The length of the water discharging pipe 603 is less than or equal to the rated suction height of the water pump, larger than the height of the car, and not enough to move around the car by half a circle, so that the car washer has to move along with a user during car washing to completely spray around the car; and

(28) 4. The water discharging pipe, the water gun, etc. can be placed in the box body.
