Description
Technical field
The present invention relates to the multi-functional anhydrous protector of a kind of hand-held garden instrument, particularly a kind of garden pump.
Background technique
Along with the development of this urban construction in several years domestic, urban afforestation has formed a very large industry.Garden instrument is as the routine servicing instrument of urban green belts, and demand is commercially also increasing.
As the one in garden instrument, garden pump mainly uses when sprinkling water to green belt, and staff is fetched water from neighbouring water source by garden pump.But in regular job, often can with some algae or other foreign material in some water sources, after above-mentioned foreign material directly enter garden pump, may extended residual in garden pump, understand the working life that directly affect garden pump like this.Therefore garden pump often first can be connected with filter in its water inlet in use, carries the water of coming first through metre filter, then enters garden pump, finally flow out from the water outlet of garden pump from water source.
Current garden pump with the use of filter function more single; after being connected to the water intake of garden pump; it can only filter the water entering garden pump, can not carry out anhydrous power-off protection to garden pump, but along with the updating of present garden instrument, innovate.The garden pump filter that above-mentioned functions is single can not meet modern Man's Demands.
Summary of the invention
The object of the invention is to provide one and garden pump with the use of rear to solve above-mentioned the deficiencies in the prior art; the current entering garden pump can be filtered; time anhydrous, power-off protection is carried out to garden pump, the multi-functional anhydrous protector of the garden pump of the current adverse current in anhydrous protector can also be prevented simultaneously.
To achieve these goals, the multi-functional anhydrous protector of the garden pump designed by the present invention, comprise cup cover, cover cap and filtering lining, filtering lining is placed in cup cover, interior pipe is provided with in described cover cap, interior pipe is interposed between the water intake of cover cap and water outlet, and the sidewall of interior pipe and the water outlet of cover cap through, cover cap is connected to the opening end of cup cover, and the port of interior pipe and filtering lining are socketed, one-way valve seat is connected with at the port of interior pipe, described one-way valve seat is positioned at filtering lining, in one-way valve seat, plug is connected to nonreturn valve core, described cover cap is provided with holding cavity, anhydrous protecting control circuit board is provided with in holding cavity, anhydrous protecting control circuit board is electrically connected with current detection switch and garden pump power line, the valve rod of nonreturn valve core is inlaid with magnet, described magnet is arranged with current detection switch is mutually corresponding.In work when current enter, the magnet on the valve rod of above-mentioned nonreturn valve core and current detection switch are connected, and when non-water flow enters, the magnet on the valve rod of above-mentioned nonreturn valve core and current detection switch disconnect.
Garden pump power line is serially connected with anhydrous protecting control circuit board in said structure; magnet on valve rod coordinates with the current detection switch on anhydrous protecting control circuit board; drive the switch conduction in anhydrous protecting control circuit board or disconnection; thus when anhydrous, power-off protection is carried out to garden pump; simultaneously due to the setting of nonreturn valve core, the present invention can also prevent the current adverse current in anhydrous protector.
As preferably, described in the multi-functional anhydrous protector of above-mentioned garden pump, anhydrous protecting control circuit board comprises SMT_CPU_HT48R01C processor IC
