Further, described intracavity section is circle, and described Connection Block is provided with the spool chamber identical and coaxial with intracavity section, is provided with spool in spool chamber, spool one end extends to inner chamber, the amount that the position of described switching control pilot core in spool chamber sprays from described nozzle with the liquid regulating in described liquid kettle.Need adjustable liquid spray volume according to difference.
Further, described spool is provided with interconnecting part near the end of nozzle, and described switch is rotatably connected on described handle, the interlock of switch upper end and spool, interconnecting part and the nozzle valve nozzles that offsets under switch releasing orientation.By the movement of handle linkage controlling valve core, thereby regulate the position of interconnecting part to change the area being communicated with sap cavity, can reach the object of the amount of liquid of Control Nozzle ejection.
Further, described Connection Block is provided with the contiguous block that end is transferred on Connection Block outward, and contiguous block is connected with described valve core rotation; On Connection Block, also switching has toggle, and toggle is provided with positive stop key, and toggle can go to the position that positive stop key and contiguous block are offseted.When positive stop key and contiguous block offset, contiguous block cannot move, thereby switch cannot be pressed, thereby realizes the locked function of a key.
Further, the junction of described conduit and described liquid kettle is provided with and allows gas to flow to the check valve in liquid kettle from conduit.Thereby the gas that prevents from entering liquid kettle is taken liquid backflow and is caused power set to damage.
Adopt after technique scheme, tool of the present invention has the following advantages:
Liquid kettle is arranged on spray gun top and can utilizes liquid gravity to improve the jet power of liquid, can reduce backwater problem simultaneously.
Brief description of the drawings
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the schematic diagram of an embodiment of the present invention;
Fig. 2 is cutaway view embodiment illustrated in fig. 1.
Detailed description of the invention
Fig. 1-2 is depicted as a kind of embodiment of the present invention.
A kind of spray gun, comprise body, body is provided with liquid kettle 3 and power set 4 outward, body comprises handle 5, the gun platform 1 being connected with power set 4 and the Connection Block 2 being connected with liquid kettle 3, handle 5, Connection Block 2, gun platform 1 are mutually permanently connected, and handle 5 is provided with the switch 51 of controlling power set 4 start and stop, is also provided with hall sensor 52 in handle 5, press the rear hall sensor 52 of switch 51 and connect, power set 4 just can be started working; Power set 4 are for producing the jet power unit of air pressure, gun platform 1 is provided with isolated inner chamber 11 and exocoel 12 mutually, Connection Block 2 is provided with sap cavity 21, power set 4 air pressure outputs are communicated with exocoel 12, exocoel 12 is communicated with liquid kettle 3 tops by conduit 31, conduit 31 is provided with and allows gas to flow to the check valve 32 in liquid kettle 3 from conduit 31 with the junction of liquid kettle 3, thereby the gas that prevents from entering liquid kettle 3 is taken liquid backflow and caused power set 4 to damage; Liquid kettle 3 bottoms are communicated with sap cavity 21, and sap cavity 21 is communicated with inner chamber 11, and inner chamber 11 front ends are provided with nozzle 13.
Inner chamber 11 cross sections are circle, Connection Block 2 is provided with the spool chamber 22 identical and coaxial with inner chamber 11 cross sections, in spool chamber 22, be provided with spool 23, spool 23 one end are stretched in inner chamber 11 and are provided with endways under switch 51 releasing orientations and the offset interconnecting part 231 of valve nozzles 13 of nozzle 13, spool 23 other ends offset with spool chamber 22 inwalls by the spring 24 that makes spool 23 produce the trend that props up nozzle 13, switch 51 is rotatably connected on handle 5, outside Connection Block 2, be provided with the contiguous block 53 that end is transferred on Connection Block 2, contiguous block 53 middle parts are connected with spool 23, thereby switch 51 and spool 23 are linked, the outer toggle 54 that is also provided with of Connection Block 2, toggle 54 is provided with positive stop key 55, toggle 54 can be allocated to positive stop key 55 and contiguous block 53 are offseted position that restriction contiguous block 53 moves, thereby play the effect of discharge cock, thereby the amount of liquid of nozzle 13 is controlled the position of spool 23 in spool chamber 22 and is flowed to the area adjusting that regulates interconnecting part 231 and be communicated with sap cavity 21 in 23 interlocks of switch 51 upper ends and spool.By the movement of handle 5 linkage controlling valve cores 23, thereby regulate the position of interconnecting part 231 to change the area being communicated with sap cavity 21, can reach the object of the amount of liquid that Control Nozzle 13 sprays, according to the adjustable liquid spray volume of difference needs.
