Description

Hand-held cleaning steam gun

Technical field

The invention belongs to steam cleaner, it can be mainly used in general cleaning, it is greasy to deoil, and also can be used for places such as sterilizing.This steam cleaner is the cleaning steam instrument that is applicable to family expenses of lightweight portable.

Background technology

In the prior art as U.S. Pat 6,314, though the sort of household steam cleaning rifle that is disclosed among the 972B1 also is with portable, but be provided with the add-on parts of much filling in the steam generator inner chamber in order to obtain enough steam, to increase contact area, this is added to the resistance that steam flows on the contrary, causes the steam pressure loss of energy of ejection.

Summary of the invention

Technical problem to be solved by this invention provides the portable household steam cleaning rifle that a kind of compact conformation is reasonable, layout is simple and clear.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: it has the housing that is hold by one hand of rifle shape, described housing preferred design becomes to cut open along the vertical guide symmetry, involutory back is an one with the screw secure bond, a water receiver is arranged, its capacity is between 200～600 grams, being removable lining mode is connected on the rifle body rearward end, be furnished with a delivery hose in the described water receiver, the delivery port of one end and water receiver is connected, the other end is a free end, is fixed with a weight bulb as the water sucking mouth on its free end termination and rests the water receiver bottom.Be provided with supply-water pump in the rifle body, described supply-water pump is a manual pump, is constantly pulled by the deduction of pistol and promotes plunger motion, the water in the water receiver is delivered to the water inlet of electric heating steam generator.Described steam generator, it is arranged in the gun barrel inside of rifle body along the longitudinally of rifle body.Described steam generator includes plate shaped support, and its material is a light-alloy, described support on two planes the U type groove that caves inward is arranged up and down, the heat pipe vapour pipe installation in position of powering respectively.Outwards outstanding fixation clamp is arranged on the described support two sides, be used for steam generator and rifle shape housing are mutually permanently connected.The electrical power of described U type electrothermal tube is between 800～1500 watts.On the end face of steam generator, lay a temperature-sensitive element, the power supply of when temperature exceeds design temperature, cutting off the electricity supply automatically.Described steam generator is fixed in the described rifle shell after wrapping up by heat-insulating material.The water inlet of the vapour pipe of described steam generator is connected with the delivery port of hand water pump.Be connected to one on the vapour pipe of the described steam generator outlet termination and extend the outer tube connector of gun barrel outward, can external various cleaners by described tube connector, as hard tube, flexible pipe, take brush of steam vent or the like out of.The water inlet of water pump is connected with the weight suction nozzle that sinks to the bottom of water receiver by a flexible pipe.The venthole of the vapour pipe of described steam generator is installed in the locational spray vapour lock of rifle mouth and is connected with one.It is characterized in that: the described water pump of a. is a manual pump, it is disposed on the position of rifle shape deduction, the deduction of pulling becomes the power source of pump by hand, described deduction formula water pump includes the cavity volume of oneself, as the deduction of plunger with contain deduction and the deduction shell of guiding is provided for its reciprocating motion, deduction is connected with the compression spring behind, and the effect of spring is after the finger finger pressure motion of deduction is finished deduction to be automatically reset.The chamber of hand water pump has two check valves to lay respectively on the water inlet and delivery port of inlet channel and outlet conduit.When deduction was withheld by finger, the check valve that is in water inlet was closed, and the water in the water pump chamber is sent to the entrance point of the U-shaped vapour pipe of steam generator by the check valve in exit under the compressing of deduction; Become hot water immediately and boiling becomes steam at the vapour pipe inner cold water of U-shaped, when deduction under the effect of compression spring in the automatically reset process, the exit check valve of deduction water pump is closed, and the water inlet check valve is just opened automatically, and the water in the water receiver replenishes the water cavity that enters manual pump by pipeline.B. described water receiver is removable lining mode and is disposed in the end that gun barrel extends backward.C. scribble the heat-curable coating that high temperature resistant, nontoxic polysiloxanes is a main component on the vapour pipe internal face of described steam generator, this coating can be brought out the diffusion that promotes water, increase effective contact area of cold water and heat pipe inwall, thereby increase the generating capacity of steam.D. described water receiver is a detached type with being connected of rifle shape housing, and its ways of connecting is the buckle ways of connecting.One arc cavity is arranged on rifle shape housing, an open-work is arranged in it, described arc cavity cooperates with an arc lock dog, and both width equate that substantially the arc length of only described arc cavity is greater than the arc length of described arc lock dog.Described arc lock dog is provided with the snap close of projection, outwards outstanding elastic claw is arranged on two sides of described snap close, both formation are and can be used for water receiver is locked in rifle shape housing along the movable relatively lockset of arc direction after on the arc cavity that described arc lock dog is installed on the described rifle shape housing.When mounted, earlier the elastic claw on the described arc lock dog snap close two sides is drawn and passes in the open-work of rifle shape housing arc cavity, allow described elastic claw flick naturally then, like this, described arc lock dog just forms removable lining the connection mutually with rifle shape housing, that is to say that both connect together, and the arc lock dog can move in the space that the arc cavity is limited along arc direction, and this motion is exactly to finish the action that water receiver is loaded onto locking or unblanked to unload toward rifle shape housing.Interconnecting the place at water receiver and rifle shape housing states secter pat prominent before is arranged on the water receiver, on described secter pat, offer the chamfered groove of an opening towards " L " of rifle shape housing type, insertion with the snap close that caters to described arc lock dog, after the snap close on the described arc lock dog inserts the opening of described " L " type chamfered groove, with the arc lock dog along the chamfered groove of " L " type towards laterally stirring, water receiver is done relative locking with rifle shape housing, and described arc lock dog has just entered lock-out state.

Compared with prior art, the invention has the advantages that: except that the common exposed surface of cleaning, can also be to surfaces such as the corner that is difficult to touch, slit, kitchen range, clean easily, and need not the independently pipeline in steam generation source and long delivering vapor, easy to operate, only need to connect power supply and cocking, just can finish cleaning; Also can be used for cleaning gold-silver ornaments.In addition, the rifle body be can be hold by one hand during operation, rag, the foul that limit spraying steam limit erasing is cleaned, better effects if like this gripped with the another hand more simultaneously.
