Description

Water supply device for car washing machine

Technical Field

The utility model relates to a be used for wasing the outside car washer of vehicle, especially one kind is used for retaining, carries the device of water for domestic car washer is supporting.

Background

The device mainly faces to the China market and meets the self-service car washing requirements of Chinese car owners. With the advance of China into a deeply aging society, young labor becomes expensive, prices of car washing shops are increasing day by day, life styles of self-service car washing are gradually popularized, and electric tools for self-service car washing also rapidly get to the market. The self-service car washing of Chinese car owners faces the following difficulties:

1. the parking place is inconvenient for car washing: different from the single residence owned by most Americans; for example, the residents in Shanghai mostly live in high buildings, the residents do not have courtyards at home, the residents cannot stop at the door, and even the residents can only stop in underground garages. Then, it is difficult to pull a water pipe and a wire for car washing. The problem of power supply is well solved, and electric car washing tools similar to a rechargeable drill and powered by a lithium battery are popularized; such as the wecker brand hand held washer manufactured by suzhou baoched technology, as shown in fig. 6.

2. Difficulty in water supply: the problem is solved by means of a water bucket, for example, a vehicle is parked at the roadside and then water is filled upstairs, and two buckets of water are lifted for moving. The process is very laborious, the water bucket shakes to easily wet the ground and trouser legs, water has to be filled less to avoid overflowing, and the actual volume utilization rate of the water bucket is only seven times.

3. The water bucket supplies water to the car washer: when the machine is powered on, the plunger pump starts to operate, but it does not spray immediately because the lengthy inlet pipe is full of air. The plunger pump needs to be airborne for two minutes, dry rubbed, and used as an air pump to evacuate the air from the water line. The lithium battery cleaning machine is not only tired of people for a long time, but also consumes electricity, and the actual working time is shortened; for example, a wecker car washer, the total operating time of the battery is only 15 minutes. For manufacturers, increasing the capacity of lithium batteries can greatly increase the cost and affect the sales volume. And for hand-held washing machines, it also means more bulky and laborious to use the wrist. More seriously, in order to deal with the dry friction heat generation when the plunger pump idles, the cost must be increased, and a plunger with better quality and a heat-resistant leather cup are adopted.

4. Disadvantages of hand-held cleaning machines: the advantage is the elimination of the high-pressure outlet pipe of a conventional washer, such as the washer K2 kaichz germany, but the disadvantage is that the inlet pipe becomes lengthy, for example up to ten meters in length as in the aforementioned waggon. The storage is troublesome: it takes five minutes to throw the remaining water from the water inlet pipe a little bit clean, otherwise it gets into the trunk of the car and gets wet the car.

The utility model discloses aim at abandoning the cask to the water pocket replaces, and the water pipe of collocation innovative design solves above difficult problem.

Disclosure of Invention

The design scheme is as follows: the water bag is used for storing water, the butt joint of the water bag and the water pipe is flexible, and particularly, the water pipe and the water bag are in a separated state when water is injected; otherwise the user is not well pinched by both hands. The water filling port of the water bag is required to be provided with a cover which is connected with the water filling port into a whole, so that the water can be stored in a sealed mode, and the cover is not easy to lose. The most commonly used material at present is PVC or PU, which has cost advantages.

Because the hardness of the two materials is low, the butt joint of the water injection port and the water pipe joint has multiple modes.

The preferred scheme is as follows: the joint of the water pipe is made into a convex shape, commonly called as a male plug, and is inserted into the water injection port and tightly hooped by the male plug, so that the sealing and fastening effects are realized. The scheme can be directly inserted by bare hands without using threaded fastening. Especially, on the protruding plug of water pipe, set up recess and rubber O circle, increase frictional force and double the fastening, better sealed.

The suboptimal scheme is as follows: the joint of the water pipe is in the shape of a sleeve with an internal thread and can be matched with a water injection port in the shape of an external thread and fastened and sealed after being screwed. Or a sealing gasket may be interposed between the two.

And a further design is adopted to avoid troubles caused by residual water in the water pipe. The joints at the two ends of the water pipe are made to be mutually inserted and matched, namely, after the two joints are butted, the residual water in the water pipe is stored in a sealing way.

Further, considering the requirements of another user usage scenario: the bathtub is washed in a bathroom or a parking stream riverside, and the water pipe is directly thrown into water to take water. The male head butted with the water filling port of the water sac is preferably made into a split type, such as a nipple head with a rubber O-ring and a pagoda head butted with a water pipe are fastened through threads. The nipple head is screwed off, and a filter head is butted, so that the requirement can be met.

If only one handle is arranged, namely only the handle which is in the same plane with the water filling opening is reserved, the operation is not influenced. But this should be considered a poor solution as the other handle facilitates the user to turn the bladder ninety degrees, bringing the fill port close to the ground to become the water outlet. If the handle is eliminated, the bag needs to be pinched by two hands to be turned.

Description of the drawings:

FIG. 1 shows the water bladder in a water storage state; FIG. 2 is a water pipe and two-end fitting; FIG. 3 shows a male structure of a water pipe and a water filling port structure of a water bag; FIG. 4 is a nipple part of the male water pipe; FIG. 5 is a filter net butted with a male water pipe after disassembly; FIG. 6 is a hand-held cleaning machine; fig. 7 shows a water bag water filling nozzle thread fastening scheme.

The optimal technical scheme is as follows:

the water bag is used for storing water, the water bag is made of PVC sheets through hot-pressing edge sealing, the shape of the water bag is cubic, the top surface of the water bag is provided with a handle made of hot-pressed PVC materials, and the top surface of the water bag is also provided with a water injection port with a cover connected with the top surface of the water bag into a whole through hot-pressing of PVC. The side surface is provided with another handle, when the handle is held by a hand, the water filling port is close to the ground, so that the butt-jointed water pipe is flush with the ground.

The water pipe butted with the water filling port of the water sac is provided with a male head and a female head, the female head is a typical gardening quick connector, and the male head is a typical nipple quick connector. The two can be butt jointed and matched to store the water in the water pipe in a sealing way. The male end can be directly inserted into the water filling port of the water sac by bare hands.

The inner diameter of the water bag water injection port is between 14 ~ 16 mm.

The specific implementation mode is as follows:

as shown in fig. 1, the first handle 7 and the second handle 8 are perpendicular to each other in the plane, and the water bag 9 is formed by hot-pressing PVC sheet into a cubic shape. The joint at one end of the water pipe 5 is already butted with the water filling port on the water bag.

The upper end of the water pipe in the attached figure 2 is a convex male head, the lower end of the water pipe is a concave female head, and the male head can be inserted and matched with the female head to realize sealing in the water pipe.

In fig. 3, the filler spout has a cap 13 which is integrally connected to a filler spout 14 made of PVC. The male end of the water pipe is matched with the male end of the water pipe in an opposite insertion mode, and butt joint water supply is achieved. The male head is of a split design, and is provided with a pagoda head 10 and a nipple head 16 which are internally threaded, the pagoda head and the nipple head are fastened through threads, and a rubber gasket is arranged between the pagoda head and the nipple head to realize sealing.

Fig. 4 shows the nipple configuration with a groove in the front end into which a sealing O-ring can be fastened.

In fig. 5, the nipple head is unscrewed and replaced by a filter head, 12 is the filter head, 11 is the external thread of the filter head, and the water pipe 5 and the internal thread pagoda head 10 are connected.

Fig. 6 shows a hand-held lithium battery car washer, which is shaped like a rechargeable drill of a lithium battery, wherein 5 is a water inlet pipe and 4 is a lithium battery pack.

Figure 7 shows a sub-optimal solution of the water filling port on the water bag, namely the fastening of the water pipe joint and the water filling port, which is realized by screw threads. In the figure, 14 is an outer edge for hot pressing with the water sac, and 15 is an external thread. As for the joint of the water pipe, the joint is still a pagoda head with internal threads. This solution dispenses with the nipple of the previous solution. But the user experience is not good enough, and the user is required to screw the socket with hands, which is not as convenient as direct insertion.

The utility model has the advantages that:

not only solves the four problems; moreover, a user fills water upstairs, the water is stored in the water bag in a sealed mode and is placed in the car trunk, the water does not need to worry about overflowing, the parking space is suitable for car washing when the car is parked, and the car is washed when the car is parked, so that the convenience in time and space is fully utilized.

The water pipe is easy to store, residual water in the spin-drying pipe is not needed, and the male head and the female head of the water pipe are directly butted and then stored. When the car is washed again, the plunger pump does not need to be used as an air pump any more, and water can be discharged in one second. When the plunger pump is designed, long-time idle running heating of the plunger pump is not needed to be considered, so that the process requirement is reduced, and the cost is reduced.
