Embodiment
Below with reference to attached drawing, the utility model will be further described, it is necessary to which explanation, following embodiments are with this
Premised on technical solution, detailed embodiment and specific operating process are given, but the scope of protection of the utility model is simultaneously
It is not limited to the present embodiment.
As shown in figures 1 to 6, a kind of spray gun for surface cleaning apparatus, including shell body 1 and lever 2, the shell body 1
Front end be nozzle 3；The rear end of the shell body 1 is equipped with two siccative entrances 4,5 and a water inlet 6；One of siccative
Entrance 4 is communicated in the rear end entrance of the siccative passage 7 in the shell body 1, the front end exit of the siccative passage 7 with it is described
Nozzle 3 is connected；After another siccative entrance 5 and the water inlet 6 are then communicated in the mixing chamber 8 in the shell body 1
(in the present embodiment, siccative entrance 5 and the water inlet 6 are communicated to mixing chamber to end entrance 81,82 by a small pipeline respectively
8 rear end entrance 81,82), the front end exit 83 of the mixing chamber 8 is then communicated in the wet feed passage 9 in the shell body 1
Rear end entrance, the front end exit of the wet feed passage 9 connects with the nozzle 3.
The blocking piece 10 for separably blocking 8 front end exit of mixing chamber, the siccative passage are equipped with the mixing chamber 8
7 outside is equipped with the closeouts 11 for the front end exit for separably blocking the siccative passage 7；The bottom connection of the blocking piece 10
There is connecting rod 12, the bottom position of the mixing chamber 8 and shell body 1 is accordingly respectively equipped with the guiding extended along anteroposterior direction
The guide groove 84 and 100 of mixing chamber 8 and shell body 1 is stretched out in groove 84 and 100, the lower end of the connecting rod 12 successively, and with propulsion
Structure 13 connects；The top of the closeouts 11 is equipped with connecting rod 14, and the corresponding position in top of the shell body 1 is equipped with along front and rear
The guide groove 15 of direction extension, the upper end of the connecting rod 14 are stretched out the guide groove 15 and are connected with promotion part 16.
The operation principle of the spray gun for surface cleaning apparatus is：When not in use, the blocking piece and closeouts
Block respectively in the front end exit of the mixing chamber and the front end exit of the siccative passage.In use, two by spray gun
Siccative entrance is communicated in the abrasive containers of sand-blasting machine by pipeline respectively, and the water inlet of spray gun is communicated in sand-blasting machine by pipeline
Water outlet (water can be liquid water, or water vapour).When needing to carry out wet blast, after sand-blasting machine is started,
First hang on (in order to abrasive material and water is all reached mixing chamber and be sufficiently mixed), then promotes the pushing structure to transport backward
Dynamic, so as to promote blocking piece to move the front end exit for opening mixing chamber backward, then the abrasive material after humidifying is in compressed air (existing spray
Sand machine is usually that compressed air is pressed into abrasive containers, and abrasive material is pressed toward spray gun) under the action of, it is pressed towards by wet feed passage
Nozzle ejects, and after use, again promotes pushing structure forward, so as to blocking blocking piece before mixing chamber again
Bring out mouth.Similarly, when needing to carry out dry type sandblasting, after sand-blasting machine is started, the pushing part is promoted to move forward, so that
Closeouts are promoted to be moved along opening the front end exit of siccative passage, then abrasive material is led under the action of compressed air by siccative
Road is pressed towards nozzle and ejects, and after use, again promotes pushing part backward, so as to closeouts be blocked again dry
Expect the front end exit of passage.
Spray gun provided by the utility model for surface cleaning apparatus, can carry out wet type abrasive jet and dry type respectively
The injection of abrasive material, and both are mutually independent of each other, wet shotcrete technology or dry-type jetting can only be carried out by having broken existing spray gun
Limitation.
Further, the bottom of the mixing chamber 8 and the bottom of the shell body 1 fit, both 84 Hes of guide groove
100 size and location is completely corresponding；The 84 corresponding position of guide groove of the interior bottom of the mixing chamber 8 and the mixing chamber 8
Equipped with two seals bar 16,17 (can use plastic sealed bar), 16,17 opposite side of two seals bar separably fits
(there is part overlapping in i.e. opposite side, in the present embodiment, has part to be superimposed on sealing strip 17 therewith for the side of sealing strip 16
On opposite side) and the guide groove 84 of the mixing chamber 8 is blocked completely, opposite side then fits in the mixing chamber 8 completely
Interior bottom (being bonded using bonding agent), the lower end of the connecting rod 12 is through two seals bar 16,17.
The setting purpose of sealing strip is in preventing abrasive material from being leaked out from guide groove.The mistake that connecting rod 12 moves in guide groove
Cheng Zhong, after connecting rod is left, the sealing strip of corresponding part will be bonded again, then except the part that connecting rod passes through, guide groove
Other parts all can be covered and be blocked by the corresponding part of two seals bar, effectively can prevent abrasive material from being leaked from guide groove
Go out.
Further, the length and width of the top surface of the push structure 13 is slightly larger than the guiding of the shell body 1 respectively
The length and width of groove 100, and be bonded with the outer bottom of the shell body 1.By above-mentioned design, the push structure can be with
Play the role of closing guide groove.With reference to the setting of sealing strip, push structure, which can shelter from sealing strip all the time and be connected bar, to be passed through
Part, further effectively can prevent abrasive material from being leaked out from guide groove.
Further, the both sides of the push structure 13 are respectively arc-shaped depression structure 131.This can be designed so that
The movement of push structure is more prone to operate.
Further, the inner top of the shell body 1 is equipped with twice guide groove sealing strip with the 15 corresponding position of guide groove
18th, 19 (can use plastic sealed bar), 18,19 opposite side of twice guide groove sealing strip separably fits (i.e. opposite
There is part overlapping in side, in the present embodiment, has part to be superimposed on sealing strip 19 on the other side one for the side of sealing strip 18
On side) and the guide groove 15 is blocked completely, the inner top that opposite side then fits in the shell body 1 completely (is glued using bonding agent
Connect), the connecting rod 14 is through twice guide groove sealing strip.
Similar with the setting of sealing strip, during connecting rod 14 is mobile in guide groove, after connecting rod leaves, corresponding part is led
Groove sealing strip will be bonded again, then except the part that connecting rod passes through, the other parts of guide groove all can be by twice guide groove sealing strip
Corresponding part covers and blocks, and effectively can prevent abrasive material from being leaked out from guide groove.
Further, the length and width of the bottom surface of the promotion part 16 is slightly larger than the length and width of the guide groove respectively
Degree, and be bonded with the outer top of the shell body 1.Similarly, confined bed can be played by above-mentioned design, the promotion part
The effect of groove.With reference to the setting of guide groove sealing strip, promotion part can shelter from the part that guide groove sealing strip is passed through by connecting rod all the time, can
Further effectively to prevent abrasive material from being leaked out from guide groove.
Further, the both sides of the promotion part 16 are respectively arc-shaped depression structure 161.This, which can be designed so that, pushes away
Movement into portion is more prone to operate.
For those skilled in the art, technical solution that can be more than and design, provide various corresponding
Change and deformation, and all these change and deformation, should be construed as being included in the utility model claims protection domain it
It is interior.
