[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0055] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0056] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0057] See appendix Figure 1 This utility model proposes a handheld water spray gun. The handle 2000 includes a grip body 3 and a pressing member 4. The grip body 3 has a water inlet channel 301. The pressing member 4 is slidably mounted on the grip body 3 and extends into the water inlet channel 301 to adjust the flow rate of the water inlet channel 301. The nozzle 1000 is rotatably mounted on the grip body 3. The nozzle 1000 has a first water outlet channel 101 and a second water outlet channel 102. Rotating the nozzle 1000 can drive the first water outlet channel 101 and / or the second water outlet channel 102 to connect with the water inlet channel 301. The first water outlet channel 101 and the second water outlet channel 102 are each connected to water outlets of different shapes or sizes, thus forming different water output modes. Similarly, the nozzle 1000 can also be provided with a third water outlet channel 103, a fourth water outlet channel, etc. The following description uses the example of the nozzle 1000 having only two water outlet channels.

[0058] The water inlet channel 301 of the grip 2000 is connected to the water source, and the pressing part 4 is installed on the grip body 3. (See attached diagram) Figure 2 One end 41 of the pressing element 4 extends into the water inlet channel 301, while the other end 42 is exposed outside the gripping body 3 for user operation. When the user applies external force to the pressing element 4, it can be driven to slide, thereby blocking or opening the water inlet channel 301. The sliding stroke of the pressing element 4 can be controlled according to the magnitude of the external force applied by the user, which can also adjust the water volume.

[0059] At least a portion of the surface of the grip body 3 is set in a cylindrical or other shape that is easy for users to grip and operate, and its surface is covered with anti-slip material so that users can hold it firmly in a wet environment or during long-term operation.

[0060] The nozzle 1000 is cylindrical or conical in shape, or a combination of both. The nozzle rotates relative to the handle 2000 about the axis of the cylindrical or conical shape, allowing the user to quickly switch water flow modes. When the user rotates the nozzle 1000, they can selectively connect either the first water outlet channel 101 or the second water outlet channel 102 in the nozzle 1000 to the water inlet channel 301 of the handle 2000, or simultaneously connect both the first water outlet channel 101 and the second water outlet channel 102 to the water inlet channel 301.

[0061] In one embodiment, the handheld water spray gun has two water outlet modes. The first water outlet channel 101 and the second water outlet channel 102 each correspond to one of these modes. Switching between the water outlet channels 101 and 102 allows for switching between or simultaneous use of the water outlet modes. For example, the first water outlet channel 101 can be in a converging flow mode, suitable for washing vehicles, floors, or other stubborn stains requiring high pressure and large amounts of water. The second water outlet channel 102 can be in a spray mode, suitable for irrigating plants or cleaning easily damaged surfaces requiring a wide area and low impact. Both modes can also be used simultaneously to meet diverse usage needs. In other embodiments, the handheld water spray gun also has a third or more water outlet modes, in which case the nozzle 1000 has three or more corresponding water outlet channels. (See attached diagram). Figure 8 , attached Figure 8 This illustration shows an embodiment where the nozzle 1000 has three water outlet channels.

[0062] Furthermore, the nozzle 1000 is installed on the top 32 of the grip body 3, and the water outlet direction of the first water outlet channel 101 and the second water outlet channel 102 is the same as the water inlet direction of the water inlet channel 301; the pressing member 4 extends out from the outside of the grip body 3 and is set close to the top 32, and the sliding direction of the pressing member 4 is perpendicular to the water inlet direction of the water inlet channel 301.

[0063] In this embodiment, the water outlet direction of the first water outlet channel 101 and the second water outlet channel 102 is the same as the water inlet direction of the water inlet channel 301, forming a straight line. Eliminating the bends between the water inlet channel 301 and the water outlet channel reduces water flow resistance. This is especially suitable for application scenarios requiring a concentrated water flow mode, such as kitchen cleaning or floor cleaning, where the straight water flow concentrates the impact force and improves the cleaning effect.

[0064] The pressing element 4 is located on the outer side of the grip body 3, near the top 32, in an area easily accessible to the user's thumb. During use, the user can hold the grip body 3 and press the pressing element 4 with their thumb to adjust the flow rate of the water inlet channel 301. This allows the user to operate the spray gun and adjust the flow rate with one hand, improving the portability of the device.

[0065] Further, see appendix. Figure 5 and attached Figure 6 In this embodiment, the handle 2000 includes a connecting seat 5 for connecting the nozzle 1000, and a water inlet channel 301 is provided through the connecting seat 5; the nozzle 1000 includes a housing 1 and a water distribution component 2, the housing 1 is rotatably mounted on the connecting seat 5, the housing 1 has an installation cavity 11, the water distribution component 2 is installed in the installation cavity 11, the water distribution component 2 divides the installation cavity 11 to form a first water outlet channel 101 and a second water outlet channel 102, that is, the first water outlet channel 101 and the second water outlet channel 102 are actually formed on the water distribution component 2, and the water outlet mode can be switched by changing the relative position relationship between the water distribution component 2 and the connecting seat 5.

[0066] Specifically, the connecting seat 5 connects the gripping body 3 and the housing 1, and the connecting seat 5 is fixedly installed on the gripping body 3. The housing 1 can rotate relative to the connecting seat 5. The water inlet channel 301 opens into the connecting seat 5, and water flows from the connecting seat 5 into the mounting cavity 11 of the housing 1 to introduce water flow from the outside into the nozzle 1000. The housing 1 can be made of materials such as metal or plastic. The water distribution component 2 divides the mounting cavity 11 of the housing 1 into two parts, forming a first water outlet channel 101 and a second water outlet channel 102. When the nozzle 1000 is rotated, the water distribution component 2 rotates synchronously with the housing 1, and a relative rotation occurs between the water distribution component 2 and the connecting seat 5, thereby switching the connection relationship between each water outlet channel and the water inlet channel 301.

[0067] Furthermore, the water distribution component 2 and the connecting seat 5 are tightly fitted to prevent the first water outlet channel 101 and the second water outlet channel 102 from being connected between the water distribution component 2 and the connecting seat 5. If there is a gap between the water distribution component 2 and the connecting seat 5, the water in the inlet channel 301 will flow from the gap to both the first water outlet channel 101 and the second water outlet channel 102 simultaneously. In other words, the first water outlet channel 101 and the second water outlet channel 102 are connected by the gap, and the rotation of the nozzle 1000 cannot drive the switching of the water outlet channels. Therefore, the water distribution component 2 and the connecting seat 5 should be tightly fitted to prevent water from entering between the water distribution component 2 and the connecting seat 5, ensuring that the water flow can selectively flow between the first water outlet channel 101 and the second water outlet channel 102 according to the user's needs, thereby achieving precise switching of the water outlet mode. For example, when the user selects to connect only the first water outlet channel 101 to the water inlet channel 301, it prevents the water flow in the water inlet channel 301 from being transmitted from the water distribution component 2 and the connecting seat 5 to the second water outlet channel 102, thus preventing the problem of chaotic water outlet patterns.

[0068] Further, see appendix. Figure 5The connecting seat 5 includes a first seat body 51 and a first contact member 52 mounted on the first seat body 51. A water inlet channel 301 is configured to pass through the first seat body 51 and the first contact member 52. The water distribution assembly 2 includes a second seat body 21 and a second contact member 22 mounted on the second seat body 21. Both the first water outlet channel 101 and the second water outlet channel 102 are configured to pass through the second seat body 21 and the second contact member 22. The relative rotation of the first contact member 52 and the second contact member 22 achieves the switching of the water outlet mode. Furthermore, the first contact member 52 and the second contact member 22 are tightly fitted to prevent the first water outlet channel 101 and the second water outlet channel 102 from connecting between the first contact member 52 and the second contact member 22, thus preventing the aforementioned problem of inconsistent water outlet modes.

[0069] The first contact 52 is fixedly installed on the upper end 501 of the first base 51. The water inlet channel flows through the first contact 52 into the mounting cavity 11, and its upper surface contacts the second contact 22. The second contact 22 is fixedly installed on the side of the second base 21 facing the connecting seat 5. The first water outlet channel 101 and the second water outlet channel 102 are both opened onto the second contact 22 and are connected to the water inlet channel 301 only from the second contact 22. At the same time, the lower surface of the second contact 22 contacts the first contact 52. In this embodiment, the first contact 52 and the second contact 22 are independently separated from the connecting seat 5 and the water distribution assembly 2, and are made of wear-resistant materials, such as ceramic materials, which solves the problem of easy wear of the contact surface during long-term high-frequency use. The remaining first base 51 and second base 21 in the connecting seat 5 and the water distribution assembly 2 are made of materials such as metal and plastic to meet their respective strength or toughness requirements.

[0070] In addition, to ensure smooth relative rotation between the first contact 52 and the second contact 22, the surfaces of the first contact 52 and the second contact 22 that come into contact with each other are smooth surfaces. The pits or processing lines on the surface can be reduced by polishing and grinding to lower the coefficient of friction and achieve smoother relative rotation between the first contact 52 and the second contact 22 to a greater extent.

[0071] Further, see appendix. Figure 6-8 The second seat 21 has a first water outlet channel 211 and a second water outlet channel 212, and the second contact member 22 has a third water outlet channel 221 and a fourth water outlet channel 222. The first water outlet channel 211 and the third water outlet channel 221 are connected to form a first water outlet channel 101, and the second water outlet channel 212 and the fourth water outlet channel 222 are connected to form a second water outlet channel 102. (See appendix) Figure 14 The first water outlet channel 211 is formed in the middle of the second seat 21, and the second water outlet channel 212 is formed by the second seat 21 and the inner wall of the mounting cavity 11.

[0072] Furthermore, if the second contact 22 is to switch the water flow between the third water outlet 221 and the fourth water outlet 222, neither the third water outlet 221 nor the fourth water outlet 222 can be connected to the rotation center of the second contact 22. Instead, an eccentric structure design is required, such as... Figure 9 As shown.

[0073] See appendix Figure 13 The second contact 22 has a top surface 223, a bottom surface 224 and a side surface 225, a third water outlet channel 221 opening from the bottom surface 224 to the top surface 223, and a fourth water outlet channel 222 opening from the bottom surface 224 to the side surface 225.

[0074] Specifically, the third water outlet channel 221 and the fourth water outlet channel 222 can be formed by a hole-like structure formed on the second contact member 22; or they can be formed by a notch structure formed on the second contact member 22.

[0075] For example, attached Figure 10 In one embodiment shown, the second contact 22 is installed in the first water outlet channel 211, and the third water outlet channel 221 is designed as a vertical hole-shaped channel extending from the bottom surface 224 to the top surface 223 of the second contact 22, so that its upper end is connected to the first water outlet channel 211, and its lower end can be connected to the water inlet channel 301; the fourth water outlet channel 222 is designed as an "L"-shaped hole-shaped channel opening from the bottom surface 224 to the side surface 225 of the second contact 22, so that its side end is connected to the second water outlet channel 212, and its lower end can be connected to the water inlet channel 301.

[0076] For example, attached Figure 8 In another embodiment shown, the second contact 22 is installed in the first water outlet channel 211, and the third water outlet channel 221 is designed as a vertical hole-like channel that extends from the bottom surface 224 of the second contact 22 to the top surface 223, so that its upper end is connected to the first water outlet channel 211, and its lower end can be connected to the water inlet channel 301; the second contact 22 has a notch that connects its bottom surface 224 and its side surface 225, and the notch constitutes the fourth water outlet channel 222.

[0077] Therefore, as long as the first contact 52 and the second contact 22 have a water-passing structure after contact installation, whether this water-passing structure is independently formed by the second contact 22 or is formed by the first contact 52 and the second contact 22 enclosing each other, it can be regarded as the third water outlet channel 221 or the fourth water outlet channel 222 opened by the second contact 22. The second water outlet channel 212 is formed by the second seat 21 and the inner wall of the mounting cavity 11 together to form an annular water flow channel. At this time, the second contact 22 can be installed in the first water outlet channel 211, and only the second water outlet channel 212 needs to be specially designed. To facilitate the manufacturing of the second contact 22, the fourth water outlet channel 222 adopts a notch-style design. When it is necessary to switch the second water outlet channel 212 for water outlet, the water inlet channel 301 can be connected to the notch. The water flow in the direct direction changes its direction after passing through the notch, thereby guiding the water flow to the annular second water outlet channel 212.

[0078] Furthermore, since the third water outlet channel 221 and the fourth water outlet channel 222 need to adopt an eccentric structure design, the single orifice diameter has a significant limiting effect on the flow rate. Therefore, in the preferred embodiment, refer to the appendix. Figure 13 The first seat 51 has only one first water inlet channel 511, while the first contact member 52 has at least two second water inlet channels 521. Both of the at least two water inlet channels are connected to the first water inlet channel 511. The number of the third water outlet channel 221 and the fourth water outlet channel 222 are the same as the number of the second water inlet channels 521, and they are connected to the second water inlet channels 521.

[0079] For example, see Appendix Figure 11 The first contact member 52 has two second water inlet channels 521, and the two second water inlet channels 521 are circumferentially distributed about the center of the first contact member 52 within a certain included angle range.

[0080] For example, see Appendix Figure 12 and 13 The first contact member 52 has two second water inlet channels 521, which are symmetrically arranged about the center of the first contact member 52. The second contact member 22 has two third water outlet channels 221 and two fourth water outlet channels 222, which are symmetrical about the center of the second contact member 22. This can make better use of the space of the two contact members and increase the flow rate.

[0081] A first water inlet channel 511 is provided on the first seat 51, penetrating its structure, to introduce water flowing from the handle 2000. At least two second water inlet channels 521 on the first contact member 52 are connected to the first water inlet channel 511 to further distribute the water flow. Increasing the number of second water inlet channels 521 increases the water volume and improves the uniformity of the water flow. To adapt to the water inlet pattern of the first contact member 52 and maintain a uniform water flow, the number of third and fourth water outlet channels 221 on the second contact member 22 is the same as the number of second water inlet channels 521.

[0082] Further, see appendix. Figure 7-8 The system has two inlet channels 521, two outlet channels 221, and two outlet channels 222. The two inlet channels 301, the two outlet channels 221, and the two outlet channels 222 are all centrally symmetrically distributed. This symmetrical water flow path reduces the potential water pressure imbalance caused by a single channel, improving the stability and uniformity of the water output.

[0083] Further, see appendix. Figure 13 The second seat 21 is provided with a receiving groove 213, and the second contact member 22 is received in the receiving groove 213; the second seat 21 is also provided with a first positioning groove 214, and the second contact member 22 is provided with a first positioning boss 226. The first positioning boss 226 is placed in the first positioning groove 214 to prevent the second contact member 22 from rotating relative to the second seat 21.

[0084] To fix the second contact 22 to the second base 21, the receiving groove 213 of the second base 21 is adapted to the outer contour of the second contact 22, and the receiving groove 213 provides a mounting position for the second contact 22. To enable the second contact 22 to rotate integrally with the second base 21, the first positioning boss 226 is placed in the first positioning groove 214, so that the second contact 22 can be circumferentially fixedly mounted on the second base 21. In one embodiment, there are two first positioning bosses 226 and two first positioning grooves 214.

[0085] Further, see appendix. Figure 13 and attached Figure 16 The second base 21 is provided with a second positioning boss 215, and the mounting cavity 11 is provided with a second positioning groove 111. The second positioning groove 111 extends vertically, and the second positioning boss 215 can be inserted into the second positioning groove 111 from top to bottom.

[0086] The second positioning groove 111 extends vertically, forming a top-down guide structure, allowing the second positioning boss 215 to be inserted vertically into the second positioning groove 111. Besides providing guidance and positioning, the fitting design between the second positioning boss 215 and the second positioning groove 111 also has an anti-rotation function. Because the shape of the second positioning boss 215 matches the second positioning groove 111, its insertion provides circumferential restraint, thereby preventing the second seat 21 from rotating relative to the housing 1 within the mounting cavity 11.

[0087] Further, see appendix. Figure 14 The second housing 21 includes a water outlet component 23 and a mounting component 24. The mounting component 24 is installed inside the mounting cavity 11, and the second contact component 22 is installed on the mounting component 24. The first water outlet channel 211 and the second water outlet channel 212 are disposed through the mounting component 24. The water outlet component 23 has a first water outlet hole 2310 and a second water outlet hole 2320. The first water outlet hole 2310 is used to connect the first water outlet channel 211 to the outside, and the second water outlet hole 2320 is used to connect the second water outlet channel 212 to the outside. The first water outlet channel 211, the third water outlet channel 221, and the first water outlet hole 2310 together constitute the first water outlet channel 101, and the second water outlet channel 212, the fourth water outlet channel 222, and the second water outlet hole 2320 together constitute the second water outlet channel 102. The water outlet component 23 and the mounting component 24 are detachably connected, and the water outlet component 23 is detachably connected to the housing 1.

[0088] In this embodiment, the second base 21 is designed to include two parts: a mounting component 24 and a water outlet component 23, which facilitates maintenance and replacement by the user. The water outlet component 23 and the second contact component 22 are both mounted on the mounting component 24 to form the water distribution assembly 2; the second positioning boss 215 can be set on the mounting component 24 to connect the water distribution assembly 2 to the housing 1, so as to realize the synchronous rotation of the two.

[0089] When the water outlet component 23 is damaged, it can be disassembled separately for cleaning or replacement without replacing the entire nozzle 1000 assembly, which simplifies maintenance and saves costs.

[0090] In one embodiment, a notch is provided on the periphery of the mounting member 24, and the notch and the inner wall of the mounting cavity 11 form a second water outlet channel 212. The notch on the second contact member 22 and the notch on the mounting member 24 are connected and together form a second water outlet channel 102.

[0091] Further, see appendix. Figure 14The mounting component 24 is provided with a nested boss 241, and a first water outlet channel 211 is provided through the nested boss 241. The water outlet component 23 is provided with a sleeve 2311, and a first water outlet hole 2310 is provided inside the sleeve 2311. The sleeve 2311 is fitted onto the nested boss 241, and a second water outlet channel 212 surrounds the sleeve 2311. Specifically, the mounting component 24 and the water outlet component 23 are connected by the nested boss 241 and the sleeve 2311. In order to prevent water from leaking into the second water outlet channel 212 when the water flows through the connection area between the nested boss 241 and the sleeve 2311, the mating part of the nested boss 241 and the sleeve 2311 is designed as an interference fit, or a sealing component such as a sealing ring is provided between the contact surfaces.

[0092] Further, see appendix. Figure 14 The water outlet component 23 includes a first water outlet head 231 and a second water outlet head 232. A first water outlet hole 2310 and a sleeve 2311 are both disposed on the first water outlet head 231. The second water outlet head 232 is arranged around the first water outlet head 231, and a second water outlet hole 2320 is disposed on the second water outlet head 232. The second water outlet head 232 is threadedly connected to the housing 1, thereby achieving a detachable connection between the two. Multiple second water outlet holes 2320 can be provided, and these holes are arranged circumferentially around the first water outlet head 231.

[0093] In one embodiment, the second water outlet 232 is detachably sleeved on the first water outlet 231 to form a water outlet component 23; the second water outlet 232 is threadedly connected to the housing 1, that is, after the first water outlet 231 and the second water outlet 232 are combined into a water outlet component 23, it is detachably connected to the housing 1 by threads, and both the first water outlet 231 and the second water outlet 232 can be independently removed from the second base 21.

[0094] The handheld spray gun can be equipped with multiple different first water outlet heads 231 and second water outlet heads 232. Each first water outlet head 231 or second water outlet head 232 has a first water outlet hole 2310 or a second water outlet hole 2320 of different shapes or sizes, so that users can replace or make various different combinations according to their needs, providing more diverse usage modes.

[0095] For example, see Appendix Figure 15 The first water outlet 231 is designed to provide direct water flow. The first water outlet 2310 can be a single hole or a multi-hole type. The single-hole type first water outlet 2310 can be a circular hole or a long strip hole, providing a direct water flow or a fan-shaped water flow, respectively. The multi-hole type first water outlet 2310 can be configured on a flat or convex surface, providing a denser direct water flow or a diffused water flow, respectively.

[0096] The second water outlet 232 is designed to provide spray water. The second water outlet 232 has multiple second water outlet holes 2320, which are arranged circumferentially around the first water outlet 231. This distribution allows for uniform spraying and covers a larger area. The opening direction of the second water outlet holes 2320 can also be slightly tilted outwards, causing the spray water flow to form a divergent distribution, further increasing the spray coverage.

[0097] Furthermore, handheld spray guns can be combined with different pulse modes and drive mechanisms to achieve more diverse water output effects and meet the needs of specific scenarios. For example, a stable water flow provides continuous direct water spray, suitable for efficient cleaning of stubborn stains or concentrated rinsing operations; with a pulse control device, the water output presents a regular intermittent pattern, suitable for cleaning more sensitive surfaces or applications that reduce water consumption; by adjusting the pulse frequency, the intermittent rhythm of the water output can be changed, from rapid bursts to slow, intermittent sprays, flexibly adapting to different needs; with the drive mechanism, the first water head 231 is designed as a rotatable structure, and the water flow forms a spiral trajectory during the spraying process.

[0098] Further, see appendix. Figure 16 and attached Figure 17 To enable the rotation of the housing 1, the connecting seat 5 has an upper end 501 and a lower end 502. The upper end 501 of the connecting seat 5 extends into the mounting cavity 11, and the lower end 502 of the connecting seat 5 is located outside the housing 1. The upper end 501 of the connecting seat 5 is provided with a first boss 5120, which abuts against the inner wall of the mounting cavity 11. The lower end 502 of the connecting seat 5 is provided with a second boss 5130, which abuts against the outer wall of the housing 1. The housing 1 is clamped on the connecting seat 5 by the first boss 5120 and the second boss 5130, and the housing 1 is rotatably positioned between the first boss 5120 and the second boss 5130.

[0099] The bottom of the housing 1 has an annular boss 12 that matches the first boss 5120 and the second boss 5130. The annular boss 12 has a through hole 121 in the middle, which connects to the mounting cavity 11. The upper end 501 of the connecting seat 5 passes through the through hole 121 and is placed in the mounting cavity 11. In this way, the annular boss is clamped between the first boss 5120 and the second boss 5130 of the connecting seat 5, but still retains the freedom of rotation, allowing it to rotate around the connecting seat 5.

[0100] Specifically, see the appendix. Figure 16 The first seat 51 includes an upper seat 512 and a lower seat 513. A first boss 5120 is disposed on the upper seat 512, and a second boss 5130 is disposed on the lower seat 513. The upper seat 512 and the lower seat 513 are threadedly connected, and the lower seat 513 is threadedly connected to the gripping body 3.

[0101] During installation, the upper seat 512 is first inserted into the mounting cavity 11 from the top of the housing 1, penetrating the through hole 121, so that the first protrusion 5120 of the upper seat 512 enters the mounting cavity 11 of the housing 1 and fits against the inner wall of the housing 1. Next, the lower seat 513 is brought close to the upper seat 512 from the outside of the housing 1 and threaded together. During the threading process, as the lower seat 513 is gradually tightened upwards, the first protrusion 5120 presses down against the inner wall of the housing 1, while the second protrusion 5130 fits tightly against the outer wall of the housing 1 from below, firmly clamping the housing 1 between the two.

[0102] The lower seat 513 is fixed to the gripping body 3 by a threaded connection, thereby combining the first seat 51 with the gripping body 3. This connection method ensures both the stability of the installation and facilitates disassembly and replacement when needed.

[0103] Further, see appendix. Figure 1 The handle 2000 also includes a pressure rod 6, which has a first end 601 and a second end 602. The first end 601 is hinged to the grip body 3, and the second end 602 can swing around the first end 601. The pressing member 4 abuts between the first end 601 and the second end 602 and is positioned close to the first end 601. When the second end 602 swings closer to the grip body 3, it drives the pressing member 4 to slide into the water inlet channel 301. Conversely, when the second end 602 swings away from the grip body 3, it corresponds to the pressing member 4 sliding outward. Changing the sliding position of the pressing member 4 changes the flow rate of the water inlet channel 301.

[0104] See appendix Figure 2 A blocking part 302 is provided inside the water inlet channel 301, dividing the water inlet channel 301 into a first connecting channel 3011 and a second connecting channel 3012. A vertical channel 3023 is provided inside the blocking part 302, which is perpendicular to the first connecting channel 3011 and the second connecting channel 3012. A first connecting port 3021 and a second connecting port 3022 are provided on the blocking part 302. The first connecting channel 3011 communicates with the vertical channel 3023 through the first connecting port 3021, and the second connecting channel 3012 communicates with the vertical channel 3023 through the second connecting port 3022. The pressing member 4 includes a straight rod 43 and a plug 44. The plug 44 is disposed in the vertical channel 3023 and can slide along the vertical channel 3023. The straight rod 43 passes through the first connecting port 3021 and is connected to the plug 44. Sliding the straight rod 43 outward can drive the plug 44 to block the first connecting port 3021.

[0105] The handle 2000 incorporates a reset element 7 and a pressure rod 6 to achieve convenient and flexible water outlet control. In this embodiment, the pressure element 4 adopts a normally closed structure design. Specifically, the reset element 7 is located within the water inlet channel 301 and connected to the pressure element 4. The reset element 7 preferably employs a spring structure. In the initial state, the reset element 7 pushes upward against the pressure element 4, causing the plug 44 to block the first connection port 3021. After the user applies pressure to the second end 602 of the pressure rod 6, the plug 44 moves away from and opens the first connection port 3021, allowing the first connection channel 3011 to connect with the second connection channel 3012. After the user releases the external force on the pressure rod 4, the elasticity of the reset element 7 drives the plug 44 to slide back towards the first connection port 3021, restoring the pressure element 4 to its initial position. This ensures that the spray gun is in a closed state when not in use, thereby reducing water waste.

[0106] The lever 6 is hinged to the gripping body 3 at its first end 601 and abuts against the pressing element 4 near the first end 601. During operation, pressing the second end 602 of the lever 6 causes it to swing around the hinge point toward the gripping body 3. The lever 6 pushes the pressing element 4 into the water inlet channel 301, thereby adjusting the opening of the water inlet channel 301 and controlling the water flow rate. Furthermore, the contact point between the lever 6 and the pressing element 4 is designed with a smooth guide surface to ensure uniform force during pressing. The elasticity of the reset element 7, combined with the lever action of the lever 6, allows for easier pressing and ensures reliable reset of the pressing element 4 after operation.

[0107] Further, see appendix. Figure 18-19 The grip 2000 also includes a retaining ring 8 rotatably mounted on the grip body 3, and a retaining platform 61 is provided on the first end 601 of the pressure rod 6; the retaining platform 61 has an abutment surface 611 on the side facing the second end 602; when the second end 602 swings closer to the grip body 3, the retaining ring 8 can swing from the first end 601 to the second end 602 and abut against the abutment surface 611.

[0108] In this embodiment, the grip 2000 incorporates a retaining ring 8 structure to lock the pressure rod 6 at a specific angle, thus keeping the pressing member 4 fixed in a certain position, facilitating continuous use of the water dispensing function for extended periods in specific scenarios. The retaining ring 8 surrounds the outer side of the pressure rod 6's retaining platform 61 and is rotatably mounted on the grip body 3. The rotation center of the retaining ring 8 is preferably located within the range between the hinge point of the pressure rod 6 and the grip body 3 and the contact surface 611, allowing the retaining ring 8 to have both locked and released states.

[0109] The locked state refers to the state as shown in the attached document. Figure 18As shown, when the user presses the second end 602 of the lever 6, causing it to swing closer to the gripping body 3 and drive the pressing member 4 to slide to adjust the opening of the water inlet channel 301, the retaining ring 8 can swing from the first end 601 of the lever 6 towards the abutment surface 611. At this time, when the user stops pressing the lever 6, the lever 6 attempts to reset under the action of the reset member 7, and the retaining ring 8 abuts against the abutment surface 611 of the lever 6 retaining platform 61, thereby locking the current position of the pressing member 4. This locking function keeps the opening of the water inlet channel 301 constant, providing a continuous and stable water flow output.

[0110] The release state refers to the state described in the appendix. Figure 19 As shown, when the user presses the second end 602 of the lever 6 again, the retaining ring 8 can swing from the contact surface 611 to the first end 601 of the lever 6 until the retaining ring 8 completely passes the first end 601 of the lever 6. At this time, the retaining ring 8 loses its restrictive effect on the lever 6, and the lever 6 is reset to the initial position under the drive of the reset member 7. The pressing member 4 slides accordingly, so that the water inlet channel 301 is closed or the opening is reduced, thus terminating or adjusting the water flow.

[0111] In this embodiment, the gripping body 3 has a limiting end 31 at the end hinged to the pressure rod 6 to limit the swing range of the pressure rod 6 during reset. The reset member 7 connects the pressure rod 6 and the gripping body 3. When the user releases the pressure rod 6, the reset member 7 drives the pressure rod 6 to swing away from the gripping body 3 to complete the reset process. Upon completion of the reset, the pressure rod 6 abuts against the limiting end, thereby preventing excessive swinging away from the gripping body 3. This helps to limit the swing range of the pressure rod 6 to a range easily operable by hand.
