BACKGROUND OF THE INVENTION
(a) Field of the Invention The present invention relates to a water cleaners and more particularly to a high pressure water cleaner with detachable water tank comprising a water cleaner main unit, a detachable water tank.
(b) Description of the Prior Art When using a conventional high pressure water cleaner, the operator will encounter the following two problems in most cleaning situations. One is that there is no water tap available or it is restrictive to connect a hose to a water tap. In this case, the high pressure water cleaner becomes useless. The other problem is that it is impossible to achieve a satisfactory cleaning effect just by using high pressure water cleaner only. For example, when cleaning car tires, car internals, motorcycles or machine, it is required to use extra cleaning hand tools (such as towels, brushes, etc.) to perform a further cleaning work.
The present invention provides an efficient solution to the conventional water cleaner problems described above: a detachable tank not only provides water to the cleaner directly without extra water source, but also provides a place to wet and wash hand cleaning tools as well. Meanwhile, the water cleaner also can perform normal high pressure cleaner job individually by connecting to a tap water, and the water tank could be used as a conventional water bucket when detached from the cleaner.
The similar products in the market currently have two features, one is a pressure washer plus a separated bucket, it can't work without tap water; another one is a pressure washer with an integrated tight tank. Although the tight tank could supply water to keep the cleaner working, it only could work under low pressure (under 300psi), low voltage (12V
DC), and since it cannot work under real high pressure, it couldn't achieve good cleaning performance.
SUMMARY OF THE INVENTION
The present invention has been accomplished under the circumstances in view.
According to the present invention, there is provided a high pressure water cleaner with detachable water tank, comprising:
a water container for holding water and supplying water; and a water cleaner main unit, said water cleaner main unit comprising a hydraulic pump mounted therein for enhancing the pressure of supplied water, a regulator for regulating water pressure and water flow rate, an electrical drive for driving said hydraulic pump, a water outlet disposed at one lateral side thereof in communication with said hydraulic pump for connecting to a spray gun, a receptacle located on a top side thereof for receiving said water tank, a feed water connector upwardly protruding from a bottom wall of said receptacle and disposed in communication with said hydraulic pump for receiving water from said water tank upon insertion of said water tank into said receptacle, and a movable lock adapted for locking said water tank to said receptacle, wherein said water tank comprises a top opening, a check valve mounted in a bottom side thereof and detachably connected to said feed water connector, and a retainer located on the periphery for engaging said movable lock.
