Description
Technical field
The present invention relates to cleaning machine, particularly relate to hand-hold gasoline cleaner, be mainly used in and clean automobile, glass door and window, garden road, animal farm place etc.
Background technology
Cleaning machine mainly is made of water pump, power-equipment and hydraulic giant, and the output shaft of power-equipment drives the power shaft of water pump, ejects from hydraulic giant after changing the low-pressure water circulation into High-Pressure Water by water pump.Power-equipment adopts gasoline engine, diesel engine, motor usually, and particularly outstanding with gasoline, diesel oil.But there is following defective in existing cleaning machine: the first, because existing water pump volume is big, Heavy Weight can't be handed use during operation, and carries inconvenience; The second, water pump does not have cooling device, temperature rise, job insecurity.
Summary of the invention
The objective of the invention is provides a kind of compact conformation in order to overcome the shortcoming that prior art exists, and volume is little, and is in light weight, easy to operate, hand-hold gasoline cleaner safe in utilization.
The technical scheme of hand-hold gasoline cleaner of the present invention is: comprise hand-hold gasoline machine and water pump, hand-hold gasoline machine output is shaped on and connects cutting ferrule and flexible axle adapter sleeve; Water pump comprises pump seat, the pump housing, pump head and pump cover, be equipped with power shaft in the pump seat, the power shaft right-hand member is equipped with gear, and gear and bevel wheel are meshing with each other, the connection cutting ferrule and the pump seat end that it is characterized in that the hand-hold gasoline machine plug, and flexible axle adapter sleeve and power shaft plug; Described bevel wheel is shaped on internal gear and is meshed with gear on the power shaft; Pump seat is equipped with the water spacer outward, and water spacer inner ring and pump seat outer ring form a cavity, and water spacer one end connects water supply connector, and the other end connects water out adapter, and water out adapter connects water inlet through connecting flexible pipe.
Hand-hold gasoline cleaner of the present invention is directly installed on water pump on the hand-hold gasoline machine, and gasoline engine and water pump closely connect into an integral body, and pump is coaxial, both can guarantee the reliability that connects, also makes compact conformation, and complete machine is light and handy, and it is very convenient to move.Its bevel wheel is shaped on internal gear and is meshed with gear on the power shaft, compares with prior art (adopt the external gear engagement, drive the bevel wheel that is contained on the axle and rotate), with the internal gear transmission, certainly will reduce the volume and weight of water pump greatly.Its pump seat is equipped with the water spacer outward; water spacer inner ring and pump seat outer ring form a cavity; water spacer one end connects water supply connector; the other end connects water out adapter, and water out adapter is connected to the pump cover water inlet through flexible pipe, and water is come in from water supply connector; by the formed cavity of water spacer and pump seat outer ring; flow to water out adapter, the water that flows through the pump seat outer ring can cool off, protect water pump, and water pump can be worked steadily in the long term.
Hand-hold gasoline cleaner of the present invention, in its pump cover safety valve is housed, when spray nozzle clogging, the pump internal pressure raises suddenly, when being elevated to when overcoming safety valve spring power, safety valve is opened, High-Pressure Water from the higher-pressure region (delivery port) get back to low-pressure area (water inlet), form a circulation thus, can prevent to damage water pump.

Fig. 2 is the safety valve structure schematic diagram of hand-hold gasoline cleaner;
Fig. 3 is the A-A cross-sectional schematic of the safety valve of hand-hold gasoline cleaner.
The specific embodiment
The invention discloses a kind of hand-hold gasoline cleaner, as shown in Figure 1, comprise hand-hold gasoline machine and water pump, hand-hold gasoline machine output is shaped on and connects cutting ferrule 19 and flexible axle adapter sleeve 20; Water pump comprises pump seat 1, the pump housing 8, pump head 16 and pump cover 15, be equipped with power shaft 2 in the pump seat 1, power shaft 2 right-hand members are equipped with gear 3, gear 3 is meshing with each other with bevel wheel 4, the bevel wheel 4 outer thrust ball bearings 5 that are equipped with, thrust ball bearing 5 contacts with plunger 7, plunger 7 passes plunger spring 6 and is installed on the pump housing 8, the pump housing connects pump head 16, water check valve 9 is housed in the pump head 16 into and goes out water one-way valve 10, water inlet check valve 9 passes one-way valve spring and is installed in the plunger 7 right-hand member endoporus, going out water one-way valve 10 is installed on the connecting ring 24 through spring, connecting ring 24 is connected with pump cover 15, pump cover 15 is shaped on water inlet 22 and delivery port 23, delivery port 23 connects nozzle through outlet pipe, its major technology is characterised in that the connection cutting ferrule 19 of hand-hold gasoline machine plugs with pump seat 1 end, flexible axle adapter sleeve 20 plugs with power shaft 2, water pump is directly installed on the hand-hold gasoline machine, gasoline engine and water pump closely connect into an integral body, pump is coaxial, both can guarantee the reliability that connects, also makes compact conformation, complete machine is light and handy, and it is very convenient to move; Its bevel wheel 4 is shaped on internal gear 18 and is meshed with gear 3 on the power shaft 2, adopts the internal gear transmission, and volume is little, and is in light weight; Be equipped with water spacer 12 outside its pump seat 1, water spacer 12 inner rings and pump seat 1 outer ring form a cavity, and water spacer 12 1 ends connect water supply connector 11, and the other end connects water out adapter 13, and water out adapter 13 connects water inlets 22 through connecting flexible pipe 14.Water is come in from water supply connector 11, by water spacer 12 and the formed cavity of pump seat 1 cylindrical, flows to water out adapter 13, arrives pump cover 15 through connecting flexible pipe 14, and the water that flows through pump seat 1 cylindrical can play the effect of cooling water pump, and pump can be worked steadily in the long term.During operation, earlier the end of cleaning machine pump seat 1 is inserted in the connection cutting ferrule 19 of hand-hold gasoline machine, and the exposed parts of power shaft 2 is inserted in the gasoline engine flexible axle adapter sleeve 20, tighten locking handwheel 21.Start gasoline engine, flexible axle rotates by power shaft 2 driven gears 3, gear 3 is meshed with bevel wheel 4 internal gears, drive thrust ball bearing 5 rotations on bevel wheel and the bevel wheel, under the acting in conjunction of thrust ball bearing and plunger spring 6, plunger 7 is reciprocating in the plunger hole of the pump housing 8, when plunger during to left movement, water inlet check valve 9 is opened, and goes out water one-way valve 10 and closes, and water is inhaled into pump head 16; When plunger 7 (nozzle outbound course) motion to the right, water inlet check valve 9 is closed, and goes out water one-way valve 10 and opens, and the water in the pump head 16 is pressed into the delivery port 23 of pump cover 15 and discharges by gun barrel, nozzle.If nozzle is blocked by impurity, can on pump cover 15, set up safety valve 17, as Fig. 2, shown in Figure 3, when pressure is elevated to when overcoming safety valve 17 spring forces, safety valve 17 is opened, High-Pressure Water from the higher-pressure region (delivery port 23) get back to low-pressure area (water inlet 22) through spout hole 25, form a circulation thus, avoided the damage of water pump.
