However, it is easy to see that, when the all-plastic recoverable hand-buckled spray gun is not needed, once the operator mistakenly touches the pressing sheet 4, the pressing sheet 4 will pressurize the pump body 1 through the valve rod 3, and then force the pump body 1 to sequentially transfer the liquid to the valve rod 3 and the spray head 5 and finally spray the liquid, thereby resulting in the waste of the liquid.

Referring to fig. 2 and 3, in order to lock the pressing piece 4 when the all-plastic recoverable hand-buckled spray gun is not needed, in the embodiment, the valve rod 3 comprises a main pipe 6 sleeved at the liquid outlet of the pump body 1 and an auxiliary pipe 7 fixedly connected to the main pipe 6, the upper end face of the main pipe 6 is fixedly connected with a limiting block 8, and one end of the auxiliary pipe 7 far away from the main pipe 6 gradually inclines upwards and penetrates through the pressing piece 4

It should be noted that the nozzle 5 is provided at one end of the sub pipe 7 remote from the main pipe 6, and the inner diameter of the sub pipe 7 is smaller than that of the main pipe 6, so that when the liquid in the main pipe 6 is transferred to the sub pipe 7, the sub pipe 7 can pressurize and accelerate the liquid, thereby promoting the liquid to be more easily and conveniently ejected from the nozzle 5.

The bottle cap 2 comprises a connecting part 9 connected with the container and a limiting part 10 connected with the pressing sheet 4 in a rotating way, and the connecting part 9 is connected with the limiting part 10 in a rotating way. In addition, one side of the limiting part 10 far away from the connecting part 9 is provided with a sliding groove 11, and when the all-plastic recoverable hand-buckled spray gun needs to be used, the limiting block 8 slides in the sliding groove 11 in a reciprocating mode.

Specifically, when needing to use the recoverable hand button formula spray gun of plastic, operating personnel can rotate spacing portion 10 and make 8 holding of stopper hold in sliding groove 11, and then carry out the in-process that pressurizes to the pump body 1 at press piece 4 through valve rod 3, stopper 8 can reciprocate to slide in sliding groove 11, and then reduces the hindrance of spacing portion 10 to the removal of press piece 4.

And when need not use when the recoverable hand button formula spray gun of all-plastic, operating personnel can rotate spacing portion 10 and make stopper 8 break away from groove 11 that slides, and the one side that pressing piece 4 was kept away from to stopper 8 this moment and spacing portion 10 keep away from one side butt of connecting portion 9, and then when operating personnel touched pressing piece 4 by mistake, spacing portion 10 can lock pressing piece 4's rotation spacingly to reduce the waste to liquid.

With reference to fig. 2 and 3, in order to improve the locking stability of the position-limiting portion 10, the outer circumferential surface of the position-limiting portion 10 is fixedly connected with a first positioning strip 12, a second positioning strip 13 and a shifting piece 14 which are spaced from each other, the inner wall of the pressing piece 4 is provided with a positioning slot 15, and both the first positioning strip 12 and the second positioning strip 13 can be inserted into the positioning slot 15.

Specifically, when first locating strip 12 is pegged graft in locating slot 15, stopper 8 holding is in sliding groove 11, and at this moment, the cell wall of locating slot 15 lasts through first locating strip 12 and spacing portion 10 is spacing, effectively makes stopper 8 can reciprocate to slide in sliding groove 11 steadily. And when stopper 8 breaks away from groove 11 and stopper 8 keeps away from one side of pressing piece 4 and one side butt that connecting portion 9 was kept away from to spacing portion 10, second location strip 13 is pegged graft in constant head tank 15, and at this moment, the cell wall of constant head tank 15 carries on spacingly through second location strip 13 to spacing portion 10 to make spacing portion 10 can be more stable lock pressing piece 4.

It should be noted that, in the present embodiment, two first positioning bars 12 and two sliding grooves 11 are disposed, the two first positioning bars 12 are disposed in central symmetry with the axis of the limiting portion 10 as the center, and the two sliding grooves 11 correspond to the two first positioning bars 12 one by one. The second positioning strip 13 is provided with one, and the second positioning strip 13 is arranged in one of the gaps of the two first positioning strips 12, and the shifting piece 14 is arranged in the other gap of the two positioning strips, so that when the limiting part 10 needs to be rotated, an operator can directly control the limiting part 10 through the shifting piece 14.

Continuing to refer to fig. 2 and 3, and in order to reduce the possibility that valve rod 3 takes place the rotation, pressing piece 4's inner wall is seted up and is supplied spacing 8 grafting spacing groove 16, and then when the recoverable hand button formula spray gun of in-service use plastic, spacing groove 16's cell wall can be spacing valve rod 3 through spacing 8 to improve the stability of shower nozzle 5 water spray.

In addition, in the present embodiment, the structure of the sub-pipe 7 may have two structures:

referring to fig. 3 and 4, in the first configuration, the sub-pipe 7 is fixedly connected to the outer peripheral surface of the main pipe 6, the sub-pipe 7 is in a straight pipe shape, and the sub-pipe 7 is gradually inclined upward in a direction away from the main pipe 6 and finally forms an angle of 60 ° with the axis of the main pipe 6. In the second structure, the secondary pipe 7 is fixedly connected to the upper end face of the main pipe 6, the secondary pipe 7 is in a bent pipe shape, the secondary pipe 7 gradually inclines towards the periphery in the direction away from the main body and finally forms 60 degrees with the axis of the main pipe 6, and therefore when the spray head 5 sprays water, the possibility that liquid is sprayed to the hands of an operator is effectively reduced.
