In this embodiment, after the water flow enters the waterway 633 from the stop valve water inlet 631, a backward acting force is applied to the water intake baffle 6341, and the water intake spring 635 is compressed by the water intake baffle 6341, so that a gap is formed between the water intake baffle 6341 and the periphery of the front end of the waterway 633, and the water flow finally flows out from the stop valve water outlet 632. When water flows reversely, namely, the water flows in from the water outlet 632 of the stop valve and enters the tail end of the water inlet channel 633, the water flows through the water channel 633 and reaches the water inlet water baffle 6341, forward acting force is applied to the water inlet water baffle 6341, so that the water inlet water baffle 6341 abuts against the periphery of the front end of the water channel 633 more tightly, at the moment, the water flows cannot pass through the front end of the water channel 633, and therefore the water flows can be prevented from flowing backwards, and pollution is avoided.

In an embodiment, a pressure relief channel 637, an inner pressure relief support 638 and a pressure relief spring 639 are further disposed inside the valve body of the stop valve, the front end of the inner pressure relief support 638 abuts against the periphery of the front end of the pressure relief channel 637, one end of the pressure relief spring 639 abuts against the inner pressure relief support 638, the other end abuts against the end of the pressure relief channel 637, the end of the pressure relief channel 637 is connected to a pressure relief opening 6305 of the stop valve 63, the front end of the pressure relief channel 637 is communicated with the water inlet 631 of the stop valve, and the elastic force of the pressure relief spring 639 in the operating state is greater than that of the water inlet spring 635 in the operating state.

In a more specific embodiment, the inner pressure-releasing bracket 638 includes a pressure-releasing water guard 6381 and a pressure-releasing water guard 6382 connected to one end of the pressure-releasing water guard 6381, the front end of the pressure-releasing water guard 6381 abuts against the periphery of the front end of the pressure-releasing channel 637, one end of the pressure-releasing spring 639 is sleeved on the pressure-releasing water guard 6382,

More importantly, the elastic force of the pressure relief spring 639 in the working state is greater than that of the water inlet spring 635 in the working state. The advantage of setting up like this is, when rivers entered into stop valve body inside, rivers can strike pressure release breakwater 6381 and intake breakwater 6341 respectively, and the elasticity under the water inlet spring 635 operating condition is less than the elasticity under the pressure release spring 639 operating condition, like this, rivers only can break water inlet breakwater 6341 to pass through from waterway 633. If the passageway blocks up or other abnormal conditions take place, lead to the inside rivers pressure surge of stop valve body, then rivers will break pressure release breakwater 6381 to flow from stop valve pressure release opening 6305, the inside pressure of stop valve 63 will reduce like this, avoids stop valve 63 internal pressure too big, leads to taking place risk such as bursting, plays the pressure protection effect. Simultaneously like waterway, pressure release channel 637 also has the function of ending, can avoid rivers palirrhea, reduces the emergence of the pollution circumstances, plays the effect of one-way closing. The shut-off valve pressure relief port 6305 may be connected to the interior of the ceramic body to introduce a flow of water into the ceramic body.

In a specific application scenario, the stiffness coefficient of the pressure relief spring 639 may be set to be greater than that of the water inlet spring 635, so that the elastic force of the pressure relief spring 639 in the operating state is greater than that of the water inlet spring 635 in the operating state. In another specific application scenario, the compression amount of the pressure relief spring 639 in the working state may be set to be greater than that of the water inlet spring 635 in the working state, and the elastic force of the pressure relief spring 639 in the working state may also be greater than that of the water inlet spring 635 in the working state. In another specific application scenario, the two manners may be combined to make the elastic force of the pressure relief spring 639 in the working state larger than the elastic force of the water inlet spring 635 in the working state.

In an embodiment, a water inlet gasket 636 is disposed between the inner water inlet bracket 634 and the front end of the waterway channel 633, and a pressure relief gasket 630 is disposed between the inner pressure relief bracket 638 and the front end of the pressure relief channel 637.

Correspondingly, the front end of pressure release breakwater 6381 can also set up a pressure release erection column 6383, pressure release erection column 6383 with sufficient clearance has between the pressure release channel 637 front end to rivers pass through when the pressure release, the sealed 630 of pressure release sets up the end at pressure release erection column 6383, promptly the sealed 630 of pressure release hugs closely the pressure release breakwater 6381 is last, the sealed 630 of pressure release supports and holds pressure release channel 637 front end all around with between the pressure release breakwater 6381, when rivers are palirrhea like this, can ensure that the sealed effect is better between pressure release breakwater 6381 and the pressure release channel 637.

In this embodiment, in the initial state, the tip of the outer wall of the lance outer cylinder 651 is engaged with the tip of the inner wall of the lance body 61, and the lance inner cylinder 652 is fixed by the inner cylinder connector 661, so that the lance inner cylinder 652 and the lance outer cylinder 651 do not slide in the initial state.

When the spray gun driving mechanism 66 works and drives the inner cylinder connecting piece 661 to extend forwards, the tail end of the outer wall of the spray gun outer cylinder 651 is in clamping connection with the tail end of the inner wall of the spray gun body 61 in an initial state, so that the spray gun outer cylinder 651 and the spray gun body 61 actually form a locking structure and are integrated, and at the moment, the spray gun inner cylinder 652 and the spray gun outer cylinder 651 do not form a locking structure, so that the inner cylinder connecting piece 661 can apply a forward acting force to the spray gun inner cylinder 652, and the spray gun inner cylinder 652 moves together with the inner cylinder connecting piece 661, so that the aim of enabling the spray gun inner cylinder 652 to slide outwards relative to. When the spray gun inner cylinder 652 slides outwards to a proper position, the tail end of the outer wall of the spray gun inner cylinder 652 is connected with the front end of the inner wall of the spray gun outer cylinder 651 in a clamping manner, at the moment, the spray gun inner cylinder 652 and the spray gun outer cylinder 651 form a locking structure, and the spray gun outer cylinder 651 and the spray gun body 61 also form a locking structure. At this time, the spray gun driving mechanism 66 will continue to drive the inner cylinder connecting piece 661 to extend forward, and since the engaging force between the end of the outer wall of the spray gun outer cylinder 651 and the end of the inner wall of the spray gun body 61 is smaller than the engaging force between the end of the outer wall of the spray gun inner cylinder 652 and the front end of the inner wall of the spray gun outer cylinder 651, the engaging connection between the spray gun outer cylinder 651 and the spray gun body 61 will be preferentially separated, and after the two are separated, the unlocking is realized, and the spray gun outer cylinder 651 and the spray gun inner cylinder 652 are still in the locking structure, so the spray gun inner cylinder 652 and the spray gun outer cylinder 651 will move together with the inner cylinder connecting piece 661. In the above process, the spray gun inner cylinder 652 preferably slides outwards, and the spray gun outer cylinder 651 then slides outwards together with the spray gun inner cylinder 652, so that the water flow sprayed from the spray gun cleaning port 616 can sequentially clean the spray gun inner cylinder 652 and the spray gun outer cylinder 651, and the best cleaning effect is achieved.

When the spray gun driving mechanism 66 works and drives the inner cylinder connecting piece 661 to retract inwards, because the spray gun inner cylinder 652 and the spray gun outer cylinder 651 are still in a locking structure at the moment, and the spray gun outer cylinder 651 and the spray gun body 61 are in an unlocking state, the spray gun inner cylinder 652 and the spray gun outer cylinder 651 can move together with the inner cylinder connecting piece 661, so that the aim that the spray gun outer cylinder 651 drives the spray gun inner cylinder 652 to slide inwards relative to the spray gun body 61 together is fulfilled. After the spray gun outer cylinder 651 slides inwards to a proper position, the tail end of the outer wall of the spray gun outer cylinder 651 is in clamping connection with the tail end of the inner wall of the spray gun body 61 again, namely the spray gun outer cylinder 651 and the spray gun body 61 form a locking structure again. At this time, since the spray gun inner cylinder 652 and the spray gun outer cylinder 651 are also in a locked configuration, the engagement force between the distal end of the outer wall of the spray gun outer cylinder 651 and the distal end of the inner wall of the spray gun body 61 is smaller than the engagement force between the distal end of the outer wall of the spray gun inner cylinder 652 and the distal end of the inner wall of the spray gun outer cylinder 651. At this time, if the inner cylinder connecting member 661 continuously retracts inward, a backward acting force is continuously applied to the spray gun inner cylinder 652, so that the spray gun outer cylinder 651 will be separated from the spray gun body 61 first, the spray gun outer cylinder 651 continues to slide inward, and the spray gun inner cylinder 652 cannot retract, so that the embodiment of the present invention defines that the end of the spray gun outer cylinder 651 is abutted against the end of the spray gun body 61, that is, after the spray gun outer cylinder 651 and the spray gun body 61 form a locking structure, the spray gun outer cylinder 651 cannot continue to retract inward due to the abutment of the end of the spray gun body 61, and at this time, if the inner cylinder connecting member 661 continuously retracts inward, at this time, the spray gun outer cylinder 651 cannot be separated from the spray gun body 61, the snap connection between the spray gun inner cylinder 652 and the spray gun outer cylinder 651 will be separated, so that the spray gun inner cylinder 652 and the spray gun outer cylinder 651 are unlocked, and, and ultimately the lance inner barrel 652 to an initial state. In the above process, the spray gun outer cylinder 651 and the spray gun inner cylinder 652 slide inwards relative to the spray gun body 61, and then the spray gun inner cylinder 652 slides inwards relative to the spray gun outer cylinder 651, so that the water flow sprayed from the spray gun cleaning port 616 can sequentially clean the spray gun outer cylinder 651 and the spray gun inner cylinder 652, and the best cleaning effect is achieved.

In this embodiment, in order to clean the spray gun outer cylinder 651 and the spray gun inner cylinder 652 in place, the spray gun 65 is controlled to extend out of the spray gun inner cylinder 652 and then extend out of the spray gun outer cylinder 651 when extending out, and the spray gun 65 is controlled to retract into the spray gun outer cylinder 651 and then retract into the spray gun inner cylinder 652 when retracting, so that the spray gun outer cylinder 651 and the spray gun inner cylinder 652 can be cleaned regardless of extension or retraction.

In an embodiment, as shown in fig. 14 and 15, a first outer cylinder clamping groove 6531 is formed at a distal end of an outer wall of the spray gun outer cylinder 651, and a spray gun body buckle 617, which is adapted to the first outer cylinder clamping groove 6531, is formed at a distal end of an inner wall of the spray gun body 61; a spray gun inner cylinder fastener 6581 is arranged at the tail end of the outer wall of the spray gun inner cylinder 652, and a second outer cylinder clamping groove 6532 matched with the spray gun inner cylinder fastener 6581 is arranged at the front end of the inner wall of the spray gun outer cylinder 651; a clamping groove stop 6533 used for abutting against the clamping buckle 6581 of the spray gun inner barrel is arranged at the front end of the second outer barrel clamping groove 6532; the spray gun body fastener 617 and/or the first outer cylinder fastener 6531 are elastic members, and the spray gun inner cylinder fastener 6581 and/or the second outer cylinder fastener 6532 are also elastic members.

In this embodiment, the spray gun outer cylinder 651 and the spray gun body 61 can be engaged with each other through structural members (i.e., the spray gun body snap 617 and the first outer cylinder snap groove 6531), and one purpose of the engagement is to keep the spray gun outer cylinder 651 in its position in the spray gun body 61 when the spray gun is not in use (i.e., in an initial state). In this embodiment, the spray gun inner cylinder 652 and the spray gun outer cylinder 651 can also be engaged and connected by structural members (i.e., the spray gun inner cylinder engaging portion 6581 and the second outer cylinder engaging portion 6532) so that the spray gun inner cylinder 652 can be engaged with the spray gun outer cylinder 651 after the spray gun inner cylinder 652 is slid outward to a predetermined position relative to the spray gun outer cylinder 651, thereby maintaining the spray gun inner cylinder 652 at the position after the spray gun inner cylinder 652 is slid outward to the predetermined position.

Specifically, the spray gun body fastener 617 and/or the first outer cylinder fastener 6531 may be an elastic member; the spray gun inner barrel snap 6581 and/or the second outer barrel snap 6532 may be resilient members. The above arrangement has the advantage that the spray gun body snap 617 and the first outer cylinder snap groove 6531 and the spray gun inner cylinder snap 6581 and the second outer cylinder snap groove 6532 are not completely fixed, and when a certain acting force is applied, the spray gun body snap 617 and the first outer cylinder snap groove 6531 can be separated (here, the spray gun outer cylinder 651 is separated from the inside to the outside of the spray gun body 61), and the spray gun inner cylinder snap 6581 and the second outer cylinder snap groove 6532 can be separated (here, the spray gun inner cylinder 652 is separated from the outside to the inside of the spray gun outer cylinder 651), so that the spray gun inner cylinder 652 and the spray gun outer cylinder 651 can be sequentially extended and retracted.

Specifically, the notch stop 6533 provided at the front end of the second outer barrel notch 6532 is used for abutting against the spray gun inner barrel buckle 6581 to continuously slide forward, because the spray gun inner barrel 652 slides outward until the spray gun inner barrel buckle 6581 is engaged with the second outer barrel notch 6532, and at this time, the spray gun body buckle 617 is also engaged with the first outer barrel notch 6531, so that the spray gun inner barrel 652, the spray gun outer barrel 651, and the spray gun outer barrel 651 are simultaneously in the locking structure, and at this time, the spray gun inner barrel 652 needs to continuously slide outward, therefore, in the embodiment of the present invention, the notch stop 6533 is provided at the front end of the second outer barrel notch 6532, and after the spray gun inner barrel buckle 6581 is engaged with the second outer barrel notch 6532, if the inner barrel connecting member 661 continuously applies a forward acting force to the spray gun inner barrel 652, the spray gun inner barrel buckle 6581 is blocked by the notch stop 6533 and cannot continuously slide forward, so that at this time, the engaging force between the tail end of the outer wall of the The locking force between the outer wall of the spray gun outer cylinder 651 and the inner wall of the spray gun body 61 is larger than the locking force between the outer wall of the spray gun outer cylinder 651 and the inner wall of the spray gun body 61, so that the spray gun outer cylinder 651 and the spray gun body 61 are separated from each other, and the spray gun outer cylinder 651 and the spray gun inner cylinder 652 are slid together with each other outward relative to the spray gun body 61. The slot stopper 6533 and the second outer tube slot 6532 may be provided integrally or separately.

Specifically, when the inner barrel connector 661 is driven by the lance drive mechanism 66 and extends forward, the inner barrel connector 661 will apply a forward force to the lance inner barrel 652, as shown in fig. 14 and 15, at this time, since the lance body latch 617 is engaged with the first outer barrel latch slot 6531, a locking structure is formed between the lance outer barrel 651 and the lance body 61, and at this time, the lance inner barrel latch 6581 is not engaged with the second outer barrel latch slot 6532, so that the lance inner barrel 652 will be pushed by the inner barrel connector 661 and slide outward, i.e., the lance inner barrel 652 slides outward relative to the lance outer barrel 651. During the outward sliding process, the end of the outer wall of the spray gun inner cylinder 652 moves forward continuously, the spray gun inner cylinder catch 6581 thereon contacts with the second outer cylinder catch 6532 on the front end of the spray gun outer cylinder 651, as shown in fig. 16 and 17, and at the same time, since at least one of the spray gun inner cylinder catch 6581 and the second outer cylinder catch 6532 is an elastic member, the spray gun inner cylinder catch 6581 and the second outer cylinder catch 6532 will eventually contact and be engaged by the force of the inner cylinder connector 661. As shown in fig. 18 and 19, in this state, the spray gun body catch 617 engages with the first outer cylinder catch 6531, and the spray gun inner cylinder catch 6581 engages with the second outer cylinder catch 6532. When the inner barrel connecting piece 661 extends forwards, the inner barrel connecting piece 661 continues to apply a forward acting force to the spray gun inner barrel 652, since the engaging force between the spray gun body snap 617 and the first outer barrel snap groove 6531 is smaller than the engaging force between the spray gun inner barrel snap groove 6581 and the second outer barrel snap groove 6532, and the spray gun body snap ring 617 and the first outer barrel snap groove 6531 are at least provided with an elastic member, when the spray gun inner barrel 652 receives the forward acting force at this time, the spray gun body snap ring 617 and the first outer barrel snap groove 6531 are preferentially separated by the elastic force, that is, the spray gun outer barrel 651 begins to slide outwards, as shown in fig. 20 and 21, after the spray gun body snap ring 617 and the first outer barrel snap groove 6531 are completely separated, the locking structure of the spray gun outer barrel 651 and the spray gun body 61 is released, so the spray gun outer barrel 651 will continue to slide outwards, and when the spray gun outer barrel 651 slides, at this time, the lance drive mechanism 66 stops driving the inner cylinder connection 661.

When lance drive mechanism 66 drives the inner barrel connector 661 in a rearward direction, now inner barrel connector 661 will apply a rearward force to lance inner barrel 652, since the spray gun body snap 617 is separated from the first outer barrel clamp groove 6531 at this time, the spray gun inner barrel fastener 6581 and the second outer barrel clamping groove 6532 are in a clamping state, the spray gun inner cylinder 652 and the spray gun outer cylinder 651 form a locking structure, and both will slide inwardly relative to the spray gun body 61 while maintaining the current state, during the inward sliding process, the first outer cylinder clamping groove 6531 on the spray gun outer cylinder 651 is gradually contacted with the spray gun body buckle 617 on the spray gun body 61, and because at least one of the spray gun body buckle 617 and the first outer cylinder clamping groove 6531 is an elastic element, the spray gun body snap 617 and the first outer barrel detent 6531 will eventually contact and snap into engagement due to the force of the inner barrel connector 661. At this time, the end of the spray gun outer cylinder 651 cannot be retracted continuously due to the limiting function of the end of the inner wall of the spray gun body 61, the spray gun inner cylinder 652 is continuously subjected to the acting force of the inner cylinder connecting piece 661, so that the spray gun inner cylinder fastener 6581 is separated from the second outer cylinder fastening slot 6532, the spray gun inner cylinder 652 starts to retract inwards relative to the spray gun outer cylinder 651 and finally retracts to the right position, the spray gun driving mechanism 66 stops driving the inner cylinder connecting piece 661 to retract inwards, and the retracted position of the spray gun inner cylinder 652 is maintained through the inner cylinder connecting piece 661.

It should be noted that, in the embodiments of the present invention, no matter the spray gun inner cylinder 652 or the spray gun outer cylinder 651, the outward sliding is an outward sliding, a forward extending or extending, etc., and the inward sliding is an inward sliding, a backward retracting or retracting, etc. With respect to inner barrel connector 661, extending forward can also be referred to as extending forward, extending outward, extending, etc., and retracting rearward can also be referred to as retracting rearward, retracting inward, etc.

In one embodiment, the force required to engage the spray gun inner barrel catch 6581 into the second outer barrel catch 6532 is less than the latching force between the spray gun body catch 617 and the first outer barrel catch 6531. In this embodiment, when the spray gun inner cylinder 652 slides outward relative to the spray gun outer cylinder 651 until the spray gun inner cylinder catch 6581 contacts the second outer cylinder catch 6532, the spray gun inner barrel 652 continues to slide forward, at which point the spray gun inner barrel catch 6581 needs to enter the second outer barrel catch 6532, at this time, if the required acting force when the spray gun inner barrel fastener 6581 enters the second outer barrel fastener 6532 is greater than the fastening force between the spray gun body fastener 617 and the first outer barrel fastener 6531, the spray gun body fastener 617 may be separated from the first outer barrel fastener 6531 first, so that the spray gun outer barrel 651 starts to slide outwards without forming a locking structure with the spray gun inner barrel 652, therefore, the embodiment of the present invention provides an improved structure for avoiding the occurrence of this situation, such that the fastening device of the inner cylinder 6581 of the spray gun enters the second outer cylinder slot 6532 first, thereby achieving the purpose of forming the locking structure between the inner cylinder 652 of the spray gun and the outer cylinder 651 of the spray gun.

In one embodiment, the force required to engage the spray gun body latch 617 with the first outer barrel detent 6531 is less than the latching force between the spray gun inner barrel latch 6581 and the second outer barrel detent 6532. In this embodiment, when the spray gun outer cylinder 651 slides inward relative to the spray gun outer cylinder 61 until the spray gun body snap 617 contacts the first outer cylinder snap-in groove 6531, the spray gun outer cylinder 651 continues to slide forward, and at this time, the spray gun body snap-in 617 needs to enter the first outer cylinder snap-in groove 6531, and actually, the position of the spray gun body snap-in groove 617 is not changed here, but the first outer cylinder snap-in groove 6531 moves from front to back to the position of the spray gun body snap-in groove 617, so the acting force here can also be understood as the acting force of the first outer cylinder snap-in groove 6531 entering the spray gun body snap-. At this time, if the required acting force when the spray gun body buckle 617 enters the first outer cylinder clamping groove 6531 is greater than the clamping force between the spray gun inner cylinder buckle 6581 and the second outer cylinder clamping groove 6532, the spray gun inner cylinder buckle 6581 may be separated from the second outer cylinder clamping groove 6532 first, resulting in the spray gun inner cylinder 652 starting to slide inwards under the condition that the spray gun outer cylinder 651 and the spray gun outer cylinder 61 are locked, so the embodiment of the present invention provides the above structure for avoiding the occurrence of this condition, so that the spray gun body buckle 617 enters the first outer cylinder clamping groove 6531 first, and the purpose of forming the locking structure between the spray gun outer cylinder 651 and the spray gun outer cylinder 61 is achieved.

In a specific application scenario, in order to make the acting force required when the spray gun inner cylinder fastener 6581 enters the second outer cylinder fastener 6532 smaller than the fastening force between the spray gun body fastener 617 and the first outer cylinder fastener 6531, a first fastening part is arranged at the end of the first outer cylinder fastener 6531, a first inclined surface is arranged at the front end of the first fastening part, a second inclined surface is arranged at the end of the spray gun body fastener 617, and the first inclined surface and the second inclined surface are in close contact with each other to form the fastening force in the process that the spray gun inner cylinder 652 slides outwards; a second engagement portion is provided at the end of the second outer tube locking groove 6532, and a third inclined surface is provided at the end of the second engagement portion, so that when the spray gun inner tube 652 slides outward until the spray gun inner tube latch 6581 comes into contact with the end of the second engagement portion, the front end of the spray gun inner tube latch 6581 actually comes into contact with the third inclined surface, and the front end of the spray gun inner tube latch 6581 applies a force to the third inclined surface. In order to make the acting force of the spray gun inner barrel fastener 6581 entering the second outer barrel fastener 6532 smaller, the third inclined plane may be set to be inclined backward from bottom to top, meanwhile, the first inclined plane may be set to be inclined backward from bottom to top, and the second inclined plane may be set to be inclined backward from bottom to top, and the inclinations of the first inclined plane and the second inclined plane are smaller than that of the third inclined plane, that is, the first inclined plane and the second inclined plane are closer to the vertical line (the vertical line is perpendicular to the sliding direction of the spray gun outer barrel 651 and the spray gun inner barrel 652), and the third inclined plane is closer to the horizontal line, so that the third inclined plane will form a guiding function to guide the spray gun inner barrel fastener 6581 to enter the second outer barrel fastener 6532, and the first inclined plane and the second inclined plane are vertically attached and cannot be easily separated. The inclination angles of the first inclined plane and the second inclined plane can be set to be the same, and the first inclined plane and the second inclined plane are attached more tightly.

In a specific application scenario, in order to make the acting force required when the spray gun body buckle 617 enters the first outer cylinder clamping groove 6531 smaller than the clamping force between the spray gun inner cylinder buckle 6581 and the second outer cylinder clamping groove 6532, a fourth inclined surface inclined forward from bottom to top may be disposed at the front end of the spray gun body buckle 617, a fifth inclined surface inclined forward from bottom to top may be disposed at the front end of the first clamping portion, and a sixth inclined surface inclined forward from bottom to top may be disposed at the front end of the second clamping portion. In the process that the spray gun outer cylinder 651 and the spray gun inner cylinder 652 form a locking structure and slide inwards together, the sixth inclined surface is tightly contacted with the spray gun inner cylinder fastener 6581, and the sixth inclined surface and the spray gun inner cylinder fastener 6581 form a clamping force; when the spray gun outer cylinder 651 slides inward until the first engaging portion contacts the spray gun body latch 617, the fourth inclined surface actually contacts the fifth inclined surface. The inclination of the fourth inclined plane and the fifth inclined plane may be set to be greater than the sixth inclined plane, that is, the fourth inclined plane and the fifth inclined plane are closer to the horizontal line (the horizontal line is parallel to the sliding direction of the spray gun outer cylinder 651 and the spray gun inner cylinder 652), so that when the spray gun outer cylinder 651 retracts, the spray gun body latch 617 can easily enter the first outer cylinder latch 6531, and actually, the first outer cylinder latch 6531 slides to make the spray gun body latch 617 latch 6531 latch in the first outer cylinder latch 6531.

In one embodiment, as shown in fig. 22 and 23, the lateral side of the outer wall of the spray gun outer cylinder 651 is provided with an outer cylinder sliding block 6534, and the lateral side of the inner wall of the spray gun body 61 is provided with a body sliding groove 618 for the sliding of the outer cylinder sliding block 6534; the front end of the body sliding groove 618 is provided with an outer cylinder limiting block 619 for abutting against the outer cylinder sliding block 6534; an outer cylinder sliding groove 6535 is formed in the side edge of the inner wall of the spray gun outer cylinder 651; an inner cylinder sliding block which is used for sliding in the outer cylinder sliding groove 6535 is arranged on the side edge of the outer wall of the spray gun inner cylinder 652; or the spray gun inner barrel snap 6581 is slidably disposed in the outer barrel slide groove 6535, and the second outer barrel snap 6532 is disposed at the front end of the outer barrel slide groove 6535.

Specifically, the purpose of the outer cylinder slide 6534 and the body slide 618 is to allow the spray gun outer cylinder 651 to stably slide back and forth within the spray gun body 61 and to slide back and forth along the axis formed by the body slide 618 without any rotation, thereby maintaining stability of the sliding movement. The outer barrel stopper 619 disposed at the front end of the body chute 618 functions to abut against the outer barrel slider 6534 to prevent the outer barrel 651 from sliding outwardly beyond a limit position.

In a specific application scenario, an inner cylinder sliding block is arranged on a side edge of the outer wall of the spray gun inner cylinder 652, and an outer cylinder sliding groove 6535 for sliding the inner cylinder sliding block is arranged on a side edge of the inner wall of the spray gun outer cylinder 651. The purpose of the inner cylinder slide and the outer cylinder slide groove 6535 is to allow the lance inner cylinder 652 to slide back and forth stably within the lance outer cylinder 651 and to slide back and forth along the axis formed by the outer cylinder slide groove 6535 without any rotation, thereby maintaining stability of the sliding movement.

In a specific application scenario, the spray gun inner barrel snap 6581 is slidably disposed in the outer barrel slide groove 6535, and the second outer barrel snap groove 6532 is disposed at a front end of the outer barrel slide groove 6535. In this specific application scenario, the spray gun inner cylinder latch 6581 is actually used to replace the inner cylinder slider, that is, the spray gun inner cylinder latch 6581 not only can be used to engage with the second outer cylinder slot 6532, but also can be used as an inner cylinder slider, and the spray gun inner cylinder latch 6581 can slide back and forth in the outer cylinder chute 6535. As the spray gun inner barrel snap 6581 slides into the front end of the outer barrel slide slot 6535, it will gradually contact and snap into the second outer barrel snap slot 6532. The design can simplify the structures of the spray gun inner cylinder 652 and the spray gun outer cylinder 651, and the structural design is more ingenious.

In one embodiment, the spray gun body 61 is provided at the distal end thereof with an arc-shaped receiving groove 615 for receiving the inner barrel connector 661, as shown in fig. 24, the spray gun outer barrel 651 comprises an outer barrel body 653 and a rack bracket 654, and the rack bracket 654 is engaged with the distal end of the outer barrel body 653 and is used for keeping the inner barrel connector 661 flat during movement.

Since the inner cylinder connector 661 is a flexible rack gear, most of the end of the inner cylinder connector 661 needs to be received in the arc-shaped receiving groove 615 when the spray gun 65 is not in use, so that the volume of the entire spray gun 65 can be reduced. When the spray gun is used, the flexible rack needs to be taken out by the adapting gear 663, and after the flexible rack is taken out by the adapting gear 663, the flexible rack needs to be kept in a flat state so as to drive the spray gun inner cylinder 652 and the spray gun outer cylinder 651 to slide back and forth, so in order to better keep the flexible rack flat, a rack bracket 654 is added at the tail end of the outer cylinder body 653, and the flexible rack entering the spray gun inner cylinder 652 is kept flat by the rack bracket 654. The rack bracket 654 may support the flex spline during sliding, thereby maintaining the flex spline in a flat condition during sliding. An outer cylinder protective sleeve 655 can be further arranged outside the outer cylinder body 653, and the outer cylinder protective sleeve 655 is sleeved outside the outer cylinder body 653 and used for protecting the outer cylinder body 653.

In one embodiment, the lance holder 611 and the lance housing 612 are closed at their front ends to form a hollow barrel 614, and the lance 65 is disposed in the barrel 614 and slides back and forth in the barrel 614. The rear ends of the lance holder 611 and the lance housing 612 are closed to form the arc-shaped receiving groove 615.

In one embodiment, as shown in fig. 26, the spray gun body 656 includes an inner barrel 658 and a nozzle 659 disposed at the front end of the inner barrel 658, and the nozzle 659 includes a water inlet 6591 disposed at the rear end and located in the inner barrel 658 and a water outlet 6592 disposed at the front end and located outside the inner barrel 658. The spray head 657 may be sleeved on the front end of the spray nozzle 659, and the spray nozzle 659 is used for introducing the water flow in the spray gun into the spray head 657 at the front end to spray.

In one embodiment, the spray gun body 656 further comprises an inner barrel connector fastener 6561, the inner barrel connector fastener 6561 is fastened to the end of the inner barrel body 658, and the front end of the inner barrel connector 661 is fixed between the inner barrel connector 6561 and the inner barrel body 658. That is, the inner barrel connector snaps 6561 act to snap the inner barrel connector 661 between the inner barrel connector snaps 6561 and the inner barrel body 658.

The inner cylinder body 658 can further be provided with an inner cylinder protection sleeve 6562, and the inner cylinder protection sleeve 6562 can be sleeved outside the inner cylinder body 658 for protecting the inner cylinder body 658.
