[0039] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0040] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0041] An embodiment of the present invention provides a spray gun module, such as Figure 1 and Figure 2 As shown, the spray gun module 60 includes a spray gun body 61 and a water pump 62, a stop valve 63 and a spray gun 65 arranged on the spray gun body 61. The water pump 62 is provided with a water pump outlet. Figure 6 As shown, the stop valve 63 is provided with a stop valve water inlet 631 and a stop valve water outlet 632 connected to the stop valve water inlet 631, the water pump outlet is connected to the stop valve water inlet 631, and the stop valve water outlet 632 is connected to the spray gun 65; Figure 3 As shown, the spray gun 65 includes a spray gun outer barrel 651 slidably disposed in the spray gun body 61 and a spray gun inner barrel 652 slidably disposed in the spray gun outer barrel 651. Fig.25As shown, the spray gun inner tube 652 includes a spray gun body 656 and a nozzle 657 arranged at the front end of the spray gun body 656. After the water flows into the water pump 62 from the outside, it passes through the water pump outlet, the stop valve inlet 631, the stop valve outlet 632 in sequence, and is finally sprayed out by the nozzle 657, so that the user's part to be cleaned is cleaned by the nozzle 657.

[0042] In this embodiment, the continuous water flow can be converted into a pulsed water flow through the water pump 62, and the water flow can be made to flow in a specified direction through the stop valve 63. The spray gun inner tube 652 and the spray gun outer tube 651 constitute a two-stage spray gun that can slide back and forth, thereby expanding the cleaning range and spraying the water flow to the specified area to be cleaned.

[0043] In one embodiment, the spray gun body 61 includes a spray gun seat 611 and a spray gun shell 612 disposed on the spray gun seat 611. Figure 4 and Figure 5 As shown, the water pump 62 is provided with a water pump mounting groove 621, and a water pump shock-absorbing pad 623 is provided on the water pump mounting groove 621. The spray gun seat 611 is provided with a water pump connecting column 613, and a water pump shock-absorbing pad 623 is provided with a water pump connecting hole 6231 for inserting the water pump connecting column 613. The water pump connecting column 613 is provided with a water pump screw mounting hole 6131 for installing the water pump screw 622.

[0044] Specifically, the water pump shock pad 623 can be installed in the water pump installation groove 621 first, and then the water pump connection hole 6231 of the water pump shock pad 623 and the water pump screw installation hole 6131 of the water pump connection column 613 can be fixed by using the water pump screw 622, so as to realize the installation of the water pump 62 and the spray gun seat 611. The function of the water pump shock pad 623 is to reduce vibration noise, because the water pump 62 will generate vibration when working, and the vibration can be transmitted to the spray gun seat 611 through the water pump shock pad 623, so as to achieve the purpose of reducing vibration noise.

[0045] In a specific application scenario, the water pump mounting groove 621 is set as a hollow sheet structure, the water pump shock pad 623 is a cylindrical structure with the water pump connection hole 6231 inside, and a shock pad groove 6232 is set in the middle of the outer side of the water pump shock pad 623, and the shape of the shock pad groove 6232 is exactly adapted to the sheet structure, so the shock pad groove 6232 can be just inserted into the sheet structure, so that the water pump shock pad 623 can be stably fixed in the water pump mounting groove 621. A sheet structure opening can be set on the side of the sheet structure to facilitate the installation of the water pump shock pad 623 into the water pump mounting groove 621 from the sheet structure opening. In a specific application scenario, the water pump 62 can be a reciprocating pump or an electromagnetic pump, etc.

[0046] In one embodiment, the stop valve 63 includes a stop valve body, such as Figure 6 As shown, a water channel 633, an inner water inlet bracket 634 and a water inlet spring 635 are provided inside the shut-off valve body, the front end of the inner water inlet bracket 634 is abutted against the front end of the water channel 633, one end of the water inlet spring 635 is abutted against the inner water inlet bracket 634, and the other end is abutted against the end of the water channel 633, the end of the water channel 633 is connected to the shut-off valve water outlet 632, and the front end of the water channel 633 is connected to the shut-off valve water inlet 631.

[0047] In a more specific embodiment, the water inlet inner bracket 634 includes a water inlet baffle plate 6341 and a water inlet baffle column 6342 connected to the rear end of the water inlet baffle plate 6341, the front end of the water inlet baffle plate 6341 is supported around the front end of the water channel 633, and one end of the water inlet spring 635 is sleeved on the water inlet baffle column 6342.

[0048] In this embodiment, when the water flows into the water channel 633 from the water inlet 631 of the stop valve, a backward force is applied to the water inlet baffle plate 6341, and the water inlet spring 635 is compressed by the water inlet baffle plate 6341, so that a gap is generated around the water inlet baffle plate 6341 and the front end of the water channel 633, so that the water flows out from the water outlet 632 of the stop valve. When the water flows in reverse, that is, the water flows in from the water outlet 632 of the stop valve and enters the end of the water channel 633, it passes through the water channel 633 and reaches the water inlet baffle plate 6341, and applies a forward force to the water inlet baffle plate 6341, so that the water inlet baffle plate 6341 and the front end of the water channel 633 are more tightly abutted, and the water will not pass through the front end of the water channel 633, so that the water flow can be prevented from flowing back and being contaminated.

[0049] In one embodiment, a pressure relief channel 637, a pressure relief inner bracket 638 and a pressure relief spring 639 are further provided inside the stop valve body, the front end of the pressure relief inner bracket 638 is abutted against the front end of the pressure relief channel 637, one end of the pressure relief spring 639 is abutted against the pressure relief inner bracket 638, and the other end is abutted against the end of the pressure relief channel 637, the end of the pressure relief channel 637 is connected to the stop valve pressure relief port 6305 of the stop valve 63, the front end of the pressure relief channel 637 is connected to the stop valve water inlet 631, and the elastic force of the pressure relief spring 639 in the working state is greater than the elastic force of the water inlet spring 635 in the working state.

[0050] In a more specific embodiment, the pressure relief inner bracket 638 includes a pressure relief water baffle plate 6381 and a pressure relief water baffle column 6382 connected to one end of the pressure relief water baffle plate 6381. The front end of the pressure relief water baffle plate 6381 is abutted against the front end of the pressure relief channel 637. One end of the pressure relief spring 639 is sleeved on the pressure relief water baffle column 6382.

[0051] The pressure relief inner bracket 638 is similar in structure to the water inlet inner bracket 634. It is just that the end of the pressure relief channel 637 will be connected to the stop valve pressure relief port 6305 of the stop valve 63, and the end of the waterway channel 633 will be connected to the stop valve water outlet 632 of the stop valve 63. A more important point is that the elastic force of the pressure relief spring 639 in the working state is greater than the elastic force of the water inlet spring 635 in the working state. The advantage of this arrangement is that when water flows into the inside of the stop valve body, the water flow will impact the pressure relief baffle 6381 and the water inlet baffle 6341 respectively, and the elastic force of the water inlet spring 635 in the working state is less than the elastic force of the pressure relief spring 639 in the working state, so that the water flow will only flush the water inlet baffle 6341 and pass through the waterway channel 633. If the channel is blocked or other abnormal conditions occur, causing the water flow pressure inside the stop valve body to increase suddenly, then the water flow will break the pressure relief baffle 6381, and then flow out from the stop valve pressure relief port 6305, so that the pressure inside the stop valve 63 will be reduced, avoiding the risk of excessive pressure inside the stop valve 63, resulting in bursting, etc., and playing a role in pressure protection. At the same time, like the waterway channel, the pressure relief channel 637 also has a cut-off function, which can avoid water backflow, reduce the occurrence of pollution, and play a role of one-way closure. The stop valve pressure relief port 6305 can be connected to the inside of the ceramic body so as to introduce water into the ceramic body.

[0052] In a specific application scenario, the stiffness coefficient of the pressure relief spring 639 can be set to be greater than the stiffness coefficient of the water inlet spring 635, so that the elastic force of the pressure relief spring 639 in the working state is greater than the elastic force of the water inlet spring 635 in the working state. In another specific application scenario, the compression amount of the pressure relief spring 639 in the working state can be set to be greater than the compression amount of the water inlet spring 635 in the working state, and the elastic force of the pressure relief spring 639 in the working state can also be greater than the elastic force of the water inlet spring 635 in the working state. Of course, in another specific application scenario, the above two methods can be combined to make the elastic force of the pressure relief spring 639 in the working state greater than the elastic force of the water inlet spring 635 in the working state.

[0053] In one embodiment, a water inlet sealing gasket 636 is provided between the water inlet inner bracket 634 and the front end of the water channel 633, and a pressure relief sealing gasket 630 is provided between the pressure relief inner bracket 638 and the front end of the pressure relief channel 637. More specifically, the water inlet sealing gasket 636 is provided between the water inlet baffle plate 6341 and the front end of the water channel 633, and the pressure relief sealing gasket 630 is provided between the pressure relief baffle plate 6381 and the front end of the pressure relief channel 637, so as to improve the sealing effect during one-way cutoff. In a specific application scenario, a water inlet mounting column 6343 may also be set at the front end of the water inlet baffle plate 6341, and there is a sufficient gap between the water inlet mounting column 6343 and the front end of the water flow channel 633 to allow water to flow through during normal operation. The water inlet sealing gasket 636 is set at the end of the water inlet mounting column 6343, that is, the water inlet sealing gasket 636 is tightly attached to the water inlet baffle plate 6341, and the water inlet sealing gasket 636 is supported around the front end of the water channel 633 and between the water inlet baffle plate 6341. In this way, when the water flows back, a better sealing effect can be ensured between the water inlet baffle plate 6341 and the water channel 633. Correspondingly, a pressure relief mounting column 6383 may also be provided at the front end of the pressure relief water baffle plate 6381, and there is a sufficient gap between the pressure relief mounting column 6383 and the front end of the pressure relief channel 637 to allow water to flow through during pressure relief. The pressure relief sealing gasket 630 is provided at the end of the pressure relief mounting column 6383, that is, the pressure relief sealing gasket 630 is tightly attached to the pressure relief water baffle plate 6381, and the pressure relief sealing gasket 630 is supported around the front end of the pressure relief channel 637 and between the pressure relief water baffle plate 6381. In this way, when the water flows back, a better sealing effect can be ensured between the pressure relief water baffle plate 6381 and the pressure relief channel 637.

[0054] In one embodiment, the spray gun module 60 further includes a water diverter valve 64 disposed on the spray gun body 61, the water diverter valve 64 being disposed between the stop valve 63 and the spray gun 65. Figures 7 to 10As shown, the water diverter valve 64 is provided with a water diverter valve water inlet 646 and a plurality of water diverter valve water outlets 647 connected to the water diverter valve water inlet 646, the shut-off valve water outlet 632 is connected to the water diverter valve water inlet 646, and the plurality of water diverter valve water outlets 647 are connected to the inside of the spray gun 65, the water diverter valve 64 includes a water diverter valve body 641, a water diverter valve seat 642 provided on the water diverter valve body 641, a switch sheet 644, a water diverter core 645 and a water diverter valve driving mechanism 643, the water diverter valve body 641 is fixed to the spray gun body 61, and the water diverter valve seat 642 is fixed to the water diverter valve body 641, the water diversion valve driving mechanism 643 is arranged on the water diversion valve seat 642, the water diversion valve driving mechanism 643 is connected to the switch sheet 644 and is used to drive the switch sheet 644 to rotate, the switch sheet 644 and the water diversion core 645 are coaxially arranged, the switch sheet 644 is provided with a switch sheet through hole 6441, and the water diversion core 645 is provided with a plurality of water diversion core through holes 6451. The switch sheet 644 is driven to rotate by the water diversion valve driving mechanism 643, so that the switch sheet through hole 6441 is aligned with different water diversion core through holes 6451, and each water diversion core through hole 6451 is connected to a water diversion valve outlet 647.

[0055] Specifically, the water diverter valve body 641 is fixed on the spray gun body 61; the water diverter valve seat 642 is fixed on the outward side of the water diverter valve body 641; the water diverter valve driving mechanism 643 is installed on the outward side of the water diverter valve seat 642; the water diverter valve outlet 647 is installed on the side facing the inside of the water diverter valve body 641, that is, it is arranged toward the inside of the spray gun body 61 so as to be connected to the inside of the spray gun 65. The function of the water diversion valve driving mechanism 643 is to drive the switch plate 644 to rotate. Since a switch plate through hole 6441 is provided on the switch plate 644, and a plurality of water diversion core through holes 6451 are provided on the water diversion core 645, when the switch plate 644 is driven to rotate by the water diversion valve driving mechanism 643, the switch plate through hole 6441 will be aligned with different water diversion core through holes 6451, and water will flow through the switch plate through hole 6441 and the aligned water diversion core through holes 6451, and finally flow out from the water diversion valve outlet 647 corresponding to each water diversion core through hole 6451.

[0056] In this embodiment, a plurality of water-dividing core through holes 6451 are provided, and each water-dividing core through hole 6451 is connected to a corresponding water-dividing valve outlet 647 , so the water-dividing valve 64 can be used to allow one water flow to flow out through different water-dividing valve outlets 647 .

[0057] In one embodiment, the water diverter valve driving mechanism 643 includes a water diverter valve driving motor 6431 and a water diverter valve driving shaft 6432 connected to the water diverter valve driving motor 6431, a shaft fixing hole 6442 is provided in the middle of the switch sheet 644, and the end of the water diverter valve driving shaft 6432 is fixedly connected to the shaft fixing hole 6442, one of the water diverter valve water outlets 647 is connected to the spray gun cleaning port 616 on the spray gun body 61, and is used to clean the outside of the spray gun 65; the remaining water diverter valve water outlets 647 are connected to the inside of the spray gun 65 (such as Fig.11 As shown, it is specifically connected to the water inlet assembly 6591, and its structure is described in detail later).

[0058] In this embodiment, the water flow sprayed from one of the water outlets 647 of the water diverter valve 64 is used to clean the spray gun 65 in the spray gun body 61. Specifically, the spray gun 65 can be arranged in the spray gun body 61 and can be extended and retracted in the spray gun body 61. Because the spray gun 65 needs to clean the user's part to be cleaned after being extended, it is inevitable that dirt will remain on the outer wall of the spray gun 65. Therefore, one of the water outlets 647 of the water diverter valve 64 can be used to clean it. Therefore, in a specific application scenario, the water outlet 647 of the water diverter valve is not entirely connected to the inside of the spray gun 65.

[0059] In this embodiment, the water diverter valve driving motor 6431 can drive the water diverter valve driving shaft 6432 to rotate. Since the end of the water diverter valve driving shaft 6432 is fixed in the shaft fixing hole 6442, the water diverter valve driving shaft 6432 can drive the switch sheet 644 to rotate during the rotation process.

[0060] In one embodiment, the water inlet 646 of the water diverter valve is arranged on the side of the water diverter valve body 641, a part of the water diverter valve seat 642 penetrates into the water diverter valve body 641, and a water diverter valve through hole 6421 connected to the water diverter valve water inlet 646 is arranged on the side of a part of the water diverter valve body 641, and the water diverter valve outlet 647 is also arranged on the water diverter valve body 641. In a more specific application scenario, the water diverter valve outlet 647 can be provided with 4. A water diverter valve sealing ring 648 can be arranged between the water diverter core 645 and the water diverter valve body 641 to improve the sealing effect of the two.

[0061] In this embodiment, water flows in from the water diverter valve water inlet 646 on the side of the water diverter valve body 641, then passes through the water diverter valve through hole 6421 and enters the inside of the water diverter valve body 641, then passes through the switch plate through hole 6441 and the water diverter core through hole 6451, and finally flows out from each water diverter valve outlet 647. The water diverter valve outlet 647 can be provided with 4, as mentioned above, one of which is connected to the spray gun cleaning port 616 on the spray gun body 61, so as to clean the spray gun 65 in the spray gun body 61. When the water flows into the inside of the water diverter valve body 641, it specifically enters the space formed inside the water diverter valve body 641, specifically the space formed by the water diverter valve seat 642, the water diverter valve drive shaft 6432 and the switch plate 644, so that the water flows smoothly through the switch plate through hole 6441. The water-dividing core 645 is fixed in the water-dividing valve seat 642 (the part that goes deep into the water-dividing valve body), and is close to the inner wall of the water-dividing valve seat 642 on all sides, so as to prevent water from flowing out from the gap between the inner wall of the water-dividing valve seat 642 and the water-dividing core 645. The diameter of the switch sheet 644 can be set to be smaller than the diameter of the water-dividing core 645, but the switch sheet 644 and the water-dividing core 645 are coaxially arranged so that the switch sheet through hole 6441 is accurately aligned with the water-dividing core through hole 6451.

[0062] In one embodiment, a night light 67 is also provided on the spray gun body 61. The purpose of the night light 67 is to provide sufficient light when the environment is dark.

[0063] In one embodiment, the spray gun module 60 further includes a spray gun driving mechanism 66 disposed on the spray gun body 61. Figure 12 to Figure 13 As shown, the spray gun driving mechanism 66 is connected to an inner cylinder connecting member 661, and the spray gun driving mechanism 66 drives the inner cylinder connecting member 661 to extend and retract forward and backward, and the front end of the inner cylinder connecting member 661 is fixed on the spray gun inner cylinder 652; the spray gun driving mechanism 66 includes a spray gun driving motor 662 and a transfer gear 663, the spray gun driving motor 662 is connected to the transfer gear 663, the inner cylinder connecting member 661 is a flexible rack, and the transfer gear 663 is meshed with the flexible rack.

[0064] In this embodiment, the spray gun outer barrel 651 can slide back and forth inside the spray gun body 61, thereby achieving the telescopic effect of the spray gun outer barrel 651, and the spray gun inner barrel 652 can slide back and forth inside the spray gun outer barrel 651, thereby achieving the telescopic effect of the spray gun inner barrel 652. The advantage of using a two-stage spray gun is that the telescopic range of the spray gun 65 can be increased when the overall length of the spray gun 65 is limited, thereby facilitating the cleaning of the user's to-be-cleaned area. The back-and-forth sliding of the spray gun inner barrel 652 and the spray gun outer barrel 651 is driven by the spray gun drive mechanism 66.

[0065] In this embodiment, the spray gun drive motor 662 can drive the connected transfer gear 663 to rotate when working. Since the transfer gear 663 is meshed with the flexible rack, the rotation of the transfer gear 663 can be converted into the linear motion of the flexible rack. In a specific application scenario, the spray gun drive motor 662 is connected to a spray gun drive shaft, and a spray gun drive shaft connection hole 6631 is provided in the middle of the transfer gear 663, and the spray gun drive shaft is fixed in the spray gun drive shaft connection hole 6631. Or in another embodiment, the spray gun drive mechanism 66 includes a spray gun drive motor and a rotating wheel, the spray gun drive motor is connected to the rotating wheel and drives the rotating wheel to rotate, and the inner cylinder connecting member 661 is a flexible steel belt, and the rotating wheel is connected to the flexible steel belt and drives the flexible steel belt to reel or unreel.

[0066] In one embodiment, the end of the outer wall of the spray gun outer barrel 651 is snap-connected with the end of the inner wall of the spray gun body 61; when the spray gun inner barrel 652 slides outwardly into place relative to the spray gun outer barrel 651, the end of the outer wall of the spray gun inner barrel 652 is snap-connected with the front end of the inner wall of the spray gun outer barrel 651; the snap-fitting force between the end of the outer wall of the spray gun outer barrel 651 and the end of the inner wall of the spray gun body 61 is smaller than the snap-fitting force between the end of the outer wall of the spray gun inner barrel 652 and the front end of the inner wall of the spray gun outer barrel 651, and the end of the spray gun outer barrel 651 is abutted against the end of the spray gun body 61.

[0067] In this embodiment, in the initial state, the end of the outer wall of the spray gun outer barrel 651 is snap-connected with the end of the inner wall of the spray gun body 61, and the spray gun inner barrel 652 is fixed by the inner barrel connector 661, so in the initial state, neither the spray gun inner barrel 652 nor the spray gun outer barrel 651 will slide.

[0068] When the spray gun driving mechanism 66 works and drives the inner cylinder connecting member 661 to extend forward, since the end of the outer wall of the spray gun outer cylinder 651 is engaged and connected with the end of the inner wall of the spray gun body 61 in the initial state, the spray gun outer cylinder 651 actually forms a locking structure with the spray gun body 61, and the two are integrated. At this time, the spray gun inner cylinder 652 and the spray gun outer cylinder 651 do not form a locking structure, so the inner cylinder connecting member 661 will apply a forward force to the spray gun inner cylinder 652, so that the spray gun inner cylinder 652 moves with the inner cylinder connecting member 661, so as to achieve the purpose of the spray gun inner cylinder 652 sliding outward relative to the spray gun outer cylinder 651. When the spray gun inner cylinder 652 slides outward to the right position, the end of the outer wall of the spray gun inner cylinder 652 is engaged and connected with the front end of the inner wall of the spray gun outer cylinder 651, and at this time, 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. Since the clamping 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 clamping 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 clamping connection between the spray gun outer cylinder 651 and the spray gun body 61 will be separated first at this time, and unlocked after the two are separated. The spray gun outer cylinder 651 and the spray gun inner cylinder 652 are still in a locked structure, so the spray gun inner cylinder 652 and the spray gun outer cylinder 651 will move as a whole with the inner cylinder connecting piece 661, so as to achieve the purpose of the spray gun outer cylinder 651 sliding outward with the spray gun inner cylinder 652. Since in the above process, the spray gun inner barrel 652 slides outward first, and the spray gun outer barrel 651 then slides outward with the spray gun inner barrel 652, the water flow sprayed from the spray gun cleaning port 616 can clean the spray gun inner barrel 652 and the spray gun outer barrel 651 in turn to achieve the best cleaning effect.

[0069] When the spray gun driving mechanism 66 works and drives the inner barrel connector 661 to retract inward, since the spray gun inner barrel 652 and the spray gun outer barrel 651 are still in a locked structure, and the spray gun outer barrel 651 and the spray gun body 61 are in an unlocked state, the spray gun inner barrel 652 and the spray gun outer barrel 651 will move together with the inner barrel connector 661, so that the spray gun outer barrel 651 and the spray gun inner barrel 652 can slide inward relative to the spray gun body 61. After the spray gun outer barrel 651 slides inward to the right position, the end of the outer wall of the spray gun outer barrel 651 and the end of the inner wall of the spray gun body 61 are re-engaged, that is, the spray gun outer barrel 651 and the spray gun body 61 are re-locked. Since the spray gun inner barrel 652 and the spray gun outer barrel 651 are also in a locking structure at this time, the engagement force between the end of the outer wall of the spray gun outer barrel 651 and the end of the inner wall of the spray gun body 61 is smaller than the engagement force between the end of the outer wall of the spray gun inner barrel 652 and the front end of the inner wall of the spray gun outer barrel 651. At this time, if the inner barrel connector 661 continues to retract inward, a backward force will continue to be applied to the spray gun inner barrel 652, so that the spray gun outer barrel 651 will first separate from the spray gun body 61, causing the spray gun outer barrel 651 to continue to slide inward, while the spray gun inner barrel 652 cannot be retracted. Therefore, the embodiment of the present invention defines that the end of the spray gun outer barrel 651 is abutted against the end of the spray gun body 61, that is, when the spray gun outer barrel 651 and the spray gun body 61 form a locking structure, the spray gun outer barrel 651 is locked by the spray gun outer barrel 651. The spray gun body 61 is blocked by the end of the spray gun body 61 and cannot be further retracted inward. If the inner cylinder connector 661 continues to retract inward, the spray gun outer cylinder 651 cannot be separated from the spray gun body 61, and the clamping 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 the spray gun inner cylinder 652 will move with the inner cylinder connector 661, so that the spray gun inner cylinder 652 slides inward, and finally the spray gun inner cylinder 652 reaches the initial state. In the above process, the spray gun outer cylinder 651 slides inward with the spray gun body 61, and then the spray gun inner cylinder 652 slides inward relative to the spray gun outer cylinder 651, so 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, achieving the best cleaning effect.

[0070] In this embodiment, in order to fully clean the spray gun outer cylinder 651 and the spray gun inner cylinder 652, the spray gun 65 is controlled to extend the spray gun inner cylinder 652 first and then the spray gun outer cylinder 651 when it is extended, and the spray gun 65 is controlled to retract the spray gun outer cylinder 651 first and then the spray gun inner cylinder 652 when it is retracted. This ensures that the spray gun outer cylinder 651 and the spray gun inner cylinder 652 can be cleaned regardless of whether they are extended or retracted.

[0071] In one embodiment, in combination Fig.14 and Fig.15As shown, a first outer cylinder slot 6531 is provided at the end of the outer wall of the spray gun outer cylinder 651, and a spray gun body buckle 617 adapted to the first outer cylinder slot 6531 is provided at the end of the inner wall of the spray gun body 61; a spray gun inner cylinder buckle 6581 is provided at the end of the outer wall of the spray gun inner cylinder 652, and a second outer cylinder slot 6532 adapted to the spray gun inner cylinder buckle 6581 is provided at the front end of the inner wall of the spray gun outer cylinder 651; a slot stopper 6533 for resisting the spray gun inner cylinder buckle 6581 is provided at the front end of the second outer cylinder slot 6532; the spray gun body buckle 617 and / or the first outer cylinder slot 6531 are elastic parts, and the spray gun inner cylinder buckle 6581 and / or the second outer cylinder slot 6532 are also elastic parts.

[0072] In this embodiment, the spray gun outer barrel 651 and the spray gun body 61 can be connected by snapping together through a structural member (i.e., the spray gun body buckle 617 and the first outer barrel slot 6531). One purpose of the snapping together here is to keep the spray gun outer barrel 651 in its position in the spray gun body 61 when the spray gun is not in use (i.e., in the initial state). In this embodiment, the spray gun inner barrel 652 and the spray gun outer barrel 651 can also be connected by snapping together through a structural member (i.e., the spray gun inner barrel buckle 6581 and the second outer barrel slot 6532). One purpose of the snapping together here is that after the spray gun inner barrel 652 slides outwardly relative to the spray gun outer barrel 651 into position, the spray gun inner barrel 652 is snapped onto the spray gun outer barrel 651, thereby keeping the spray gun inner barrel 652 in its position after sliding outwardly into position.

[0073] Specifically, the spray gun body buckle 617 and / or the first outer cylinder slot 6531 may be an elastic member; the spray gun inner cylinder buckle 6581 and / or the second outer cylinder slot 6532 may be an elastic member. The advantage of the above arrangement is that the spray gun body buckle 617 and the first outer cylinder slot 6531 and the spray gun inner cylinder buckle 6581 and the second outer cylinder slot 6532 are not completely fixed, and when a certain force is applied, the spray gun body buckle 617 and the first outer cylinder slot 6531 can be separated (here, the spray gun outer cylinder 651 is separated from the spray gun body 61 from the inside to the outside), and the spray gun inner cylinder buckle 6581 and the second outer cylinder slot 6532 can be separated (here, the spray gun inner cylinder 652 is separated from the spray gun outer cylinder 651 from the outside to the inside), thereby realizing the sequential extension and retraction of the spray gun inner cylinder 652 and the spray gun outer cylinder 651.

[0074] Specifically, the slot stopper 6533 provided at the front end of the second outer cylinder slot 6532 is used to resist the spray gun inner cylinder buckle 6581 from continuing to slide forward. Because after the spray gun inner cylinder 652 slides outward until the spray gun inner cylinder buckle 6581 is engaged with the second outer cylinder slot 6532, the spray gun body buckle 617 is also engaged with the first outer cylinder slot 6531. Therefore, the spray gun inner cylinder 652 and the spray gun outer cylinder 651, the spray gun outer cylinder 651 and the spray gun body 61 are in a locking structure at the same time. At this time, the spray gun inner cylinder 652 needs to continue to slide outward. Therefore, in the embodiment of the present invention, the slot stopper 6533 is provided at the front end of the second outer cylinder slot 6532. When the spray gun inner cylinder is engaged, After the buckle 6581 is engaged with the second outer cylinder slot 6532, if the inner cylinder connector 661 continues to apply a forward force to the spray gun inner cylinder 652, the spray gun inner cylinder buckle 6581 will be blocked by the slot stopper 6533 and cannot continue to slide forward. Therefore, at this time, the engagement 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 is much greater than the engagement 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, so the spray gun outer cylinder 651 and the spray gun body 61 are released from the locking structure, and the two are separated, so that the spray gun outer cylinder 651 and the spray gun inner cylinder 652 slide outward together relative to the spray gun body 61. The slot stopper 6533 and the second outer cylinder slot 6532 can be provided integrally or separately.

[0075] Specifically, when the inner cylinder connecting member 661 is driven by the spray gun driving mechanism 66 and extends forward, the inner cylinder connecting member 661 will apply a forward force to the spray gun inner cylinder 652, such as Fig.14 and Fig.15 As shown, at this time, since the spray gun body buckle 617 is engaged with the first outer cylinder slot 6531, a locking structure is formed between the spray gun outer cylinder 651 and the spray gun body 61, and at this time, the spray gun inner cylinder buckle 6581 is not engaged with the second outer cylinder slot 6532, so the spray gun inner cylinder 652 is pushed by the inner cylinder connector 661 and slides outward, that is, the spray gun inner cylinder 652 slides outward relative to the spray gun outer cylinder 651. During the outward sliding process, the end of the outer wall of the spray gun inner cylinder 652 moves forward continuously, and the spray gun inner cylinder buckle 6581 thereon contacts with the second outer cylinder slot 6532 on the front end of the spray gun outer cylinder 651, as shown in FIG. Fig.16 and Fig.17 As shown, at the same time, since at least one of the spray gun inner cylinder buckle 6581 and the second outer cylinder slot 6532 is an elastic member, the spray gun inner cylinder buckle 6581 and the second outer cylinder slot 6532 will eventually contact and engage due to the force of the inner cylinder connector 661. Fig.18 and Fig.19As shown, in this state, the spray gun body buckle 617 is engaged with the first outer cylinder slot 6531, and the spray gun inner cylinder buckle 6581 is engaged with the second outer cylinder slot 6532. When the inner cylinder connecting member 661 continues to extend forward, the inner cylinder connecting member 661 continues to apply a forward force to the spray gun inner cylinder 652. Since the engagement force between the spray gun body buckle 617 and the first outer cylinder slot 6531 is smaller than the engagement force between the spray gun inner cylinder buckle 6581 and the second outer cylinder slot 6532, and the spray gun body buckle 617 and the first outer cylinder slot 6531 have at least one elastic member, when the spray gun inner cylinder 652 is subjected to a forward force, the spray gun body buckle 617 and the first outer cylinder slot 6531 will be separated first by elastic force, that is, the spray gun outer cylinder 651 starts to slide outward, as shown in FIG. Fig. 20 and Fig.21 As shown, after the spray gun body buckle 617 is completely separated from the first outer tube slot 6531, the locking structure between the spray gun outer tube 651 and the spray gun body 61 is released, so the spray gun outer tube 651 will continue to slide outward. When the spray gun outer tube 651 slides outward into place relative to the spray gun body 61, the spray gun drive mechanism 66 stops driving the inner tube connector 661.

[0076] When the spray gun driving mechanism 66 drives the inner cylinder connecting member 661 to retract backward, the inner cylinder connecting member 661 will apply a backward force to the spray gun inner cylinder 652. Since the spray gun body buckle 617 and the first outer cylinder slot 6531 are in a separated state, and the spray gun inner cylinder buckle 6581 and the second outer cylinder slot 6532 are in an engaged state, the spray gun inner cylinder 652 and the spray gun outer cylinder 651 form a locking structure, and the two will maintain the current state and slide inward relative to the spray gun body 61. During the inward sliding process, the first outer cylinder slot 6531 on the spray gun outer cylinder 651 gradually contacts the spray gun body buckle 617 on the spray gun body 61, and since at least one of the spray gun body buckle 617 and the first outer cylinder slot 6531 is an elastic member, the spray gun body buckle 617 and the first outer cylinder slot 6531 will eventually contact and engage due to the force of the inner cylinder connecting member 661. At this time, the end of the spray gun outer cylinder 651 is limited by the end of the inner wall of the spray gun body 61 and cannot continue to retract, while the spray gun inner cylinder 652 continues to be acted upon by the inner cylinder connector 661, so that the spray gun inner cylinder buckle 6581 is separated from the second outer cylinder slot 6532, so that the spray gun inner cylinder 652 begins to retract inward relative to the spray gun outer cylinder 651, and finally retracts into place, and the spray gun driving mechanism 66 stops driving the inner cylinder connector 661 to retract inward, and maintains the retracted position of the spray gun inner cylinder 652 through the inner cylinder connector 661.

[0077] It should be noted that in each embodiment of the present invention, whether it is the spray gun inner barrel 652 or the spray gun outer barrel 651, sliding outward refers to sliding outward, sliding forward, sliding forward, extending forward, extending forward, or extending, and sliding inward refers to sliding inward, sliding backward, sliding backward, retracting backward, retracting backward, or retracting, etc. For the inner barrel connector 661, extending forward can also be referred to as extending forward, extending outward, extending outward, extending, etc., and retracting backward can also be referred to as retracting backward, retracting inward, retracting inward, retracting, etc.

[0078] In one embodiment, the force required for the spray gun inner cylinder buckle 6581 to enter the second outer cylinder slot 6532 is smaller than the engagement force between the spray gun body buckle 617 and the first outer cylinder slot 6531 . In this embodiment, when the spray gun inner barrel 652 slides outward relative to the spray gun outer barrel 651 until the spray gun inner barrel buckle 6581 contacts the second outer barrel slot 6532, the spray gun inner barrel 652 continues to slide forward. At this time, the spray gun inner barrel buckle 6581 needs to enter the second outer barrel slot 6532. At this time, if the force required for the spray gun inner barrel buckle 6581 to enter the second outer barrel slot 6532 is greater than the clamping force between the spray gun body buckle 617 and the first outer barrel slot 6531, then the spray gun body buckle 617 may first disengage from the first outer barrel slot 6531, causing the spray gun outer barrel 651 to start sliding outward without forming a locking structure with the spray gun inner barrel 652. Therefore, in order to avoid this situation, the embodiment of the present invention is provided with the above structure, so that the spray gun inner barrel buckle 6581 first enters the second outer barrel slot 6532, so as to achieve the purpose of forming a locking structure between the spray gun inner barrel 652 and the spray gun outer barrel 651.

[0079] In one embodiment, the force required for the spray gun body buckle 617 to enter the first outer cylinder slot 6531 is less than the engagement force between the spray gun inner cylinder buckle 6581 and the second outer cylinder slot 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 buckle 617 contacts the first outer cylinder slot 6531, the spray gun outer cylinder 651 continues to slide forward, and at this time the spray gun body buckle 617 needs to enter the first outer cylinder slot 6531. In fact, the spray gun body buckle 617 does not move here, and the first outer cylinder slot 6531 moves from front to back to the position of the spray gun body buckle 617, so the force here can also be understood as the force of the first outer cylinder slot 6531 entering the spray gun body buckle 617. At this time, if the force required for the spray gun body buckle 617 to enter the first outer cylinder slot 6531 is greater than the clamping force between the spray gun inner cylinder buckle 6581 and the second outer cylinder slot 6532, then the spray gun inner cylinder buckle 6581 may first disengage from the second outer cylinder slot 6532, causing the spray gun inner cylinder 652 to start sliding inward when the spray gun outer cylinder 651 and the spray gun outer cylinder 61 are locked. Therefore, in order to avoid this situation, the embodiment of the present invention provides the above-mentioned structure, so that the spray gun body buckle 617 first enters the first outer cylinder slot 6531, so as to achieve the purpose of forming a locking structure between the spray gun outer cylinder 651 and the spray gun outer cylinder 61.

[0080] In a specific application scenario, in order to make the force required for the spray gun inner cylinder buckle 6581 to enter the second outer cylinder slot 6532 smaller than the clamping force between the spray gun body buckle 617 and the first outer cylinder slot 6531, a first clamping portion is provided at the end of the first outer cylinder slot 6531, a first inclined surface is provided at the front end of the first clamping portion, and a second inclined surface is provided at the end of the spray gun body buckle 617. In the process of the spray gun inner cylinder 652 sliding outward, the first inclined surface is in close contact with the second inclined surface, and the two form a clamping force; a second clamping portion is provided at the end of the second outer cylinder slot 6532, and a third inclined surface is provided at the end of the second clamping portion. When the spray gun inner cylinder 652 slides outward until the spray gun inner cylinder buckle 6581 contacts the end of the second clamping portion, it is actually the front end of the spray gun inner cylinder buckle 6581 that contacts the third inclined surface, and the front end of the spray gun inner cylinder buckle 6581 will apply a force to the third inclined surface. In order to reduce the force of the spray gun inner barrel buckle 6581 entering the second outer barrel slot 6532, the third slope can be set to a structure that tilts backward from bottom to top, and the first slope can be set to a structure that tilts backward from bottom to top, and the second slope can be set to a structure that tilts backward from bottom to top, and the inclination of the first slope and the second slope is smaller than that of the third slope, that is, the first slope and the second slope 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 slope is closer to the horizontal line, so that the third slope will form a guiding effect, guiding the spray gun inner barrel buckle 6581 to enter the second outer barrel slot 6532, while the first slope and the second slope are vertically fitted and cannot be easily separated. The inclination angles of the first slope and the second slope can be set to be the same, and the two fit more closely.

[0081] In a specific application scenario, in order to make the force required for the spray gun body buckle 617 to enter the first outer cylinder slot 6531 smaller than the clamping force between the spray gun inner cylinder buckle 6581 and the second outer cylinder slot 6532, a fourth inclined surface tilted forward from bottom to top can be provided at the front end of the spray gun body buckle 617, a fifth inclined surface tilted forward from bottom to top can be provided at the front end of the first clamping portion, and a sixth inclined surface tilted forward from bottom to top can be provided at the front end of the second clamping portion. When the spray gun outer cylinder 651 and the spray gun inner cylinder 652 form a locking structure and slide inward together, the sixth inclined surface is in close contact with the spray gun inner cylinder buckle 6581, and the two form a clamping force; when the spray gun outer cylinder 651 slides inward until the first clamping portion contacts the spray gun body buckle 617, it is actually the fourth inclined surface that contacts the fifth inclined surface. The inclination of the fourth and fifth inclined planes can be set to be greater than that of the sixth inclined plane, that is, the fourth and fifth inclined planes are closer to the horizontal line relative to the sixth inclined plane (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 is retracted, the spray gun body buckle 617 can easily enter the first outer cylinder slot 6531, and actually the first outer cylinder slot 6531 slides to make the spray gun body buckle 617 stuck in the first outer cylinder slot 6531.

[0082] In one embodiment, if Fig. 22 and Fig.23 As shown, an outer cylinder slider 6534 is provided on the side of the outer wall of the spray gun outer cylinder 651, and a body slide groove 618 for the sliding of the outer cylinder slider 6534 is provided on the side of the inner wall of the spray gun body 61; an outer cylinder limit block 619 for resisting the outer cylinder slider 6534 is provided at the front end of the body slide groove 618; an outer cylinder slide groove 6535 is provided on the side of the inner wall of the spray gun outer cylinder 651; an inner cylinder slider for sliding in the outer cylinder slide groove 6535 is provided on the side of the outer wall of the spray gun inner cylinder 652; or the spray gun inner cylinder buckle 6581 can be slidably arranged in the outer cylinder slide groove 6535, and the second outer cylinder clamping groove 6532 is arranged at the front end of the outer cylinder slide groove 6535.

[0083] Specifically, the purpose of providing the outer cylinder slider 6534 and the body slide groove 618 is to enable the spray gun outer cylinder 651 to slide back and forth stably in the spray gun body 61, and to slide back and forth along the axis formed by the body slide groove 618 without any rotation, thereby maintaining the stability of sliding. The outer cylinder limit block 619 provided at the front end of the body slide groove 618 is used to resist the outer cylinder slider 6534 to prevent the spray gun outer cylinder 651 from sliding outward beyond the limit position.

[0084] In a specific application scenario, an inner cylinder slider is provided on the side of the outer wall of the spray gun inner cylinder 652, and an outer cylinder slide groove 6535 for the inner cylinder slider to slide is provided on the side of the inner wall of the spray gun outer cylinder 651. The purpose of providing the inner cylinder slider and the outer cylinder slide groove 6535 is to enable the spray gun inner cylinder 652 to slide back and forth stably in the spray gun 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 the stability of sliding.

[0085] In a specific application scenario, the spray gun inner barrel buckle 6581 can be slidably disposed in the outer barrel slot 6535, and the second outer barrel slot 6532 is disposed at the front end of the outer barrel slot 6535. In this specific application scenario, the spray gun inner barrel buckle 6581 actually replaces the aforementioned inner barrel slider, that is, the spray gun inner barrel buckle 6581 can not only play the role of engaging with the second outer barrel slot 6532, but also play the role of an inner barrel slider, and the spray gun inner barrel buckle 6581 can slide back and forth in the outer barrel slot 6535. When the spray gun inner barrel buckle 6581 slides to the front end of the outer barrel slot 6535, it will gradually contact with the second outer barrel slot 6532 and engage in the second outer barrel slot 6532. Such a design can simplify the structure of the spray gun inner barrel 652 and the spray gun outer barrel 651, and the structural design is more ingenious.

[0086] In one embodiment, the end of the spray gun body 61 is provided with an arc-shaped receiving groove 615 for receiving the inner cylinder connecting member 661. Fig.24 As shown, the spray gun outer cylinder 651 includes an outer cylinder body 653 and a rack bracket 654. The rack bracket 654 is buckled at the end of the outer cylinder body 653 and is used to keep the inner cylinder connecting member 661 flat during movement.

[0087] Since the inner cylinder connecting member 661 is a flexible rack, most of the end of the inner cylinder connecting member 661 needs to be stored in the arc-shaped storage groove 615 when the spray gun 65 is not in use, so as to reduce the volume of the entire spray gun 65. When the spray gun is in use, the flexible rack needs to be brought out by the transfer gear 663. After being brought out by the transfer gear 663, the flexible rack needs to remain flat in order to drive the spray gun inner cylinder 652 and the spray gun outer cylinder 651 to slide back and forth. Therefore, in order to better keep the flexible rack flat, a rack bracket 654 is added to the end of the outer cylinder body 653, and the rack bracket 654 is used to keep the flexible rack entering the spray gun inner cylinder 652 flat. The rack bracket 654 can play a supporting role during the sliding process of the flexible rack, so that the flexible rack can remain flat during the sliding process. An outer cylinder protective sleeve 655 may be further provided outside the outer cylinder body 653 . The outer cylinder protective sleeve 655 is sleeved outside the outer cylinder body 653 to protect the outer cylinder body 653 .

[0088] In a specific application scenario, the front ends of the spray gun seat 611 and the spray gun housing 612 are covered to form a hollow gun barrel 614, and the spray gun 65 is disposed in the gun barrel 614 and slides back and forth in the gun barrel 614. The rear ends of the spray gun seat 611 and the spray gun housing 612 are covered to form the arc-shaped receiving groove 615.

[0089] In one embodiment, if Fig.26 As shown, the spray gun body 656 includes an inner cylinder body 658 and a nozzle 659 disposed at the front end of the inner cylinder body 658, and the nozzle 659 includes a water inlet assembly 6591 disposed at the rear end and located inside the inner cylinder body 658 and a water outlet assembly 6592 disposed at the front end and located outside the inner cylinder body 658. The spray head 657 can be sleeved at the front end of the nozzle 659, and the function of the nozzle 659 is to introduce the water flow inside the spray gun into the spray head 657 at the front end for spraying.

[0090] In one embodiment, the spray gun body 656 further includes an inner cylinder connector clamp 6561, which is buckled at the end of the inner cylinder body 658, and the front end of the inner cylinder connector 661 is fixed between the inner cylinder connector clamp 6561 and the inner cylinder body 658. That is, the inner cylinder connector clamp 6561 clamps the inner cylinder connector 661 between the inner cylinder connector clamp 6561 and the inner cylinder body 658.

[0091] An inner cylinder protective sleeve 6562 may also be provided on the inner cylinder body 658, and the inner cylinder protective sleeve 6562 may be sleeved outside the inner cylinder body 658 to protect the inner cylinder body 658. In the aforementioned embodiment, the spray gun inner cylinder 652 is provided with a spray gun inner cylinder buckle 6581, which may actually be provided on the inner cylinder body 658, and the spray gun inner cylinder buckle 6581 needs to contact the second outer cylinder buckle groove 6532 on the spray gun outer cylinder 651, and accordingly, the inner cylinder protective sleeve 6562 is provided with a buckle through hole 6507 for the spray gun inner cylinder buckle 6581 to pass through.

Obviously, the components arranged inside the nozzle are actually arranged on the nozzle body 6571, and the components arranged outside the nozzle can also be arranged on the nozzle body 6571. At the same time, a corresponding opening area can be arranged on the nozzle protective cover 6572. For example, the nozzle protective cover 6572 can be hollowed out to form a water outlet area that can be connected to the nozzle water outlet hole 6574 (actually arranged on the nozzle body 6571) so as to realize the water spraying function normally.

[0092] In one embodiment, if Fig.28 and 29 As shown, the outer wall of the water outlet component 6592 is provided with a snap-fit ​​rib 6598, and the inner wall of the nozzle 657 is provided with a nozzle slot 6573 for engaging with the snap-fit ​​rib 6598. The nozzle 657 is sleeved on the outside of the water outlet component 6592, and the nozzle 657 is provided with a plurality of nozzle water outlet holes 6574. The plurality of nozzle water outlet holes 6574 are connected with the water outlet component 6592, so that the water entering the water inlet component 6591 flows through the water outlet component 6592 and is sprayed out from the plurality of nozzle water outlet holes 6574 of the nozzle 657. In this embodiment, the nozzle 657 is engaged with the water outlet component 6592 through the nozzle slot 6573 and the engaging rib 6598. In this way, when installing the nozzle 657, it is only necessary to put the nozzle 657 on the water outlet component 6592, and then engage the engaging rib 6598 with the nozzle slot 6573. This embodiment can conveniently disassemble and assemble the nozzle 657. Since the nozzle 657 needs to use its nozzle water outlet hole 6574 to clean the user's part to be cleaned, the nozzle 657 is very easy to be contaminated. Therefore, replacement of the nozzle 657 is particularly important. This embodiment provides the above-mentioned solution, which can simplify the difficulty of nozzle replacement and improve replacement efficiency.

[0093] In this embodiment, the function of the spray gun body 656 is to introduce water flow and finally transmit it to the spray head 657, so the most core component in the spray gun body 656 is the nozzle 659. The front end of the nozzle 659 needs to be connected to the spray head 657, and the rear end of the nozzle 659 needs to be connected to the inner cylinder body 658, so the water inlet assembly 6591 is arranged inside the inner cylinder body 658, and the water outlet assembly 6592 is arranged outside the inner cylinder body 658, and the inner cylinder body 658 plays the role of carrying the nozzle 659.

[0094] In one embodiment, the water inlet assembly 6591 is provided with a plurality of nozzle water inlets 6594, and the water outlet assembly 6592 is provided with a plurality of nozzle water outlets 6597.

A nozzle blocking member 6599 for blocking different nozzle water outlets 6597 is provided on the outside of the water outlet assembly 6592. The nozzle 657 is sleeved on the outside of the water outlet assembly 6592, and the plurality of nozzle water outlet holes 6574 provided on the nozzle 657 are connected with the plurality of nozzle water outlets 6597.

[0095] The multiple nozzle water inlets 6594 are connected to the aforementioned multiple water diverter valve outlets 647. For example, if four water diverter valve outlets 647 are provided, then three nozzle water inlets 6594 can be provided. These three nozzle water inlets 6594 are respectively connected to three of the water diverter valve outlets 647, and the extra one water diverter valve outlet 647 is connected to the aforementioned spray gun cleaning port 616.

[0096] Since the nozzle blocking member 6599 is disposed between each nozzle water outlet 6597, the water flowing out of the nozzle water outlets 6597 will not affect each other, but will be discharged outward through the multiple nozzle water outlet holes 6574 disposed on the nozzle 657, so as to achieve the purpose of cleaning through different nozzle water outlet holes 6574. Of course, in another embodiment, the nozzle blocking member 6599 may not be disposed, but the water outlet assembly may be interference-fitted with the inner wall of the nozzle, that is, the outer wall of the water outlet assembly is closely disposed with the inner wall of the nozzle, so that the water flowing out of different nozzle water outlets does not affect each other.

[0097] In one embodiment, a water inlet assembly buckle 6595 is provided on the side of the water inlet assembly 6591, and an inner cylinder body snap groove 6582 is provided on the inner wall of the inner cylinder body 658 to snap into the water inlet assembly buckle 6595. In this embodiment, the nozzle 659 is fixed to the inner cylinder body 658 by snapping into the water inlet assembly buckle 6595 and the inner cylinder body snap groove 6582, so when installing the nozzle 659, it is only necessary to snap the water inlet assembly buckle 6595 into the inner cylinder body snap groove 6582.

[0098] In one embodiment, the water inlet assembly 6591 is provided with a plurality of water inlet assembly extensions 6596, a plurality of water inlet assembly buckles 6595 are provided and are respectively located at the ends of the plurality of water inlet assembly extensions 6596, and a plurality of inner cylinder body slots 6582 are provided and correspond one-to-one with the water inlet assembly buckles 6595.

[0099] In one embodiment, a connecting plate 6593 is provided between the water inlet assembly 6591 and the water outlet assembly 6592 , and the connecting plate 6593 is supported against the front end of the spray gun body 656 .

[0100] In one embodiment, the snap-fit ​​rib 6598 is located at the rear end of the water outlet assembly 6592, and the nozzle slot 6573 is located at the rear end of the nozzle 657. This makes it convenient to put the nozzle on the water outlet assembly 6592 from front to back.

[0101] In one embodiment, the snap-fit ​​rib 6598 is a cylindrical structure, and a hollow structure 6575 is provided on one side of the nozzle slot 6573 to facilitate the insertion of the snap-fit ​​rib 6598. A nozzle opening is provided on the nozzle slot 6573 on the side facing the hollow structure 6575, and the length of the nozzle opening is smaller than the diameter of the snap-fit ​​rib 6598. The snap-fit ​​rib 6598 and / or the nozzle slot 6573 are elastic parts.

[0102] In this embodiment, when the nozzle 657 is placed on the water outlet assembly 6592 from front to back, Fig.29 and Fig.30 As shown, the hollow structure 6575 can be first aligned with the snap-fit ​​rib 6598 so that the nozzle 657 can be mounted on the water outlet component 6592 and the bottom of the nozzle 657 can be in contact with the bottom of the water outlet component 6592. Since a nozzle opening is provided on the nozzle slot 6573 facing the side of the hollow structure 6575, the water outlet component 6592 and the nozzle 657 can be relatively rotated, so that the snap-fit ​​rib 6598 can be squeezed from the nozzle opening into the nozzle slot 6573.

[0103] In one embodiment, the plurality of nozzle water outlets 6597 are distributed at different axial positions of the water outlet assembly 6592. In this embodiment, the main body of the water outlet assembly 6592 is a cylindrical structure, and the nozzle water outlets 6597 are distributed at different axial positions of the water outlet assembly 6592, which means that the nozzle water outlets 6597 are distributed at different positions in the length direction of the water outlet assembly 6592, so as to facilitate the setting of the nozzle blocking member 6599 and avoid the water flows from different nozzle water outlets 6597 from affecting each other.

[0104] In one embodiment, the nozzle blocking member 6599 is a sealing rubber ring disposed around the outside of the water outlet assembly 6592. In this embodiment, since the main body of the water outlet assembly 6592 is a cylindrical structure, and the nozzle water outlets 6597 are distributed at different axial positions of the water outlet assembly 6592, in this arrangement, each nozzle blocking member 6599 is in parallel, and the nozzle water outlets 6597 are located in the space between adjacent nozzle blocking members 6599.

[0105] In one embodiment, the nozzle water inlet 6594 includes three, and correspondingly, the nozzle water outlet 6597 includes three, and they correspond one to one. In this embodiment, a three-way passage can be formed, and the water flows out from the nozzle water outlet 6597 that are connected to each other after entering from the nozzle water inlet 6594. Each nozzle water outlet 6597 is connected to the corresponding nozzle water outlet 6574, so that the water flows out from the nozzle water outlet 6574 to achieve a multi-way cleaning effect. In one embodiment, the nozzle water outlet 6574 includes three groups: a first group of nozzle water outlet holes, a second group of nozzle water outlet holes, and a third group of nozzle water outlet holes, which correspond to the three nozzle water outlets 6597 respectively; wherein, the first group of nozzle water outlet holes is arranged at the front end of the nozzle 657, and the second group of nozzle water outlet holes and the third group of nozzle water outlet holes are arranged at the rear end of the nozzle 657. In this embodiment, the first group of nozzle water holes can be used to clean women's private parts, and the second group of nozzle water holes and the third group of nozzle water holes can be used to clean the user's anus.
