[0095] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0096] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0097] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0098] In this application, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. "And / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0099] This disclosure provides an exemplary embodiment of a water gun 10, with reference to... Figures 1-4 As shown, the water gun 10 may include a barrel 1, a pull-out component 2, and a first elastic element 3; the barrel 1 has a water gun nozzle 111 and a fixed end 122 arranged opposite to each other in the first direction X, and a variable volume water storage tank 115 and a water inlet area 114 are provided inside the barrel 1. The water inlet area 114 is closer to the water gun nozzle 111 than the variable volume water storage tank 115. A water supply hole 116 is provided on the barrel wall of the water inlet area 114, and the water supply hole 116 is used to connect the water pump 20. The pull-out component 2 is disposed inside the gun barrel 1. The pull-out component 2 may include a pull-out tube 21 and a movable rod 22. The movable rod 22 is connected to the pull-out tube 21 along the first direction X. The end of the pull-out tube 21 near the water inlet area 114 is the pull-out end. The pull-out end is sealed and slidably fitted to the gun barrel 1 to form a variable volume water storage tank 115. The movable rod 22 moves along the first direction X to open or close the water gun nozzle 111. The first elastic element 3 is disposed between the pull-out tube 21 and the fixed end 122.

[0100] Reference Figure 1 As shown, the water gun 10 of this disclosure defines the state before water intake as the initial state, at which time the pull tube 21 is in the initial position. When water is introduced, the water pump 20 is turned on, and the water pump 20 fills the water intake area 114 and the variable volume water storage tank 115 with water through the water supply hole 116. As the water volume in the variable volume water storage tank 115 increases, the water pressure will push the pull tube 21 to move along the first direction X towards the fixed end 122. The pull tube 21 applies pressure to the first elastic member 3, causing the first elastic member 3 to generate a rebound force, and the movable rod 22 keeps the water gun nozzle 111 closed. Reference Figure 2As shown, when the container is nearly full of water, the pull tube 21 abuts against the movable rod 22. The water pressure causes the pull tube 21 and the movable rod 22 to move together toward the fixed end 122, thereby filling the variable volume water storage tank 115 with water and causing the movable rod 22 to open the water gun nozzle 111.

[0101] At this time, water gun nozzle 111 is in the open state, and water pump 20 is in the closed state. (Reference) Figure 3 As shown, the water gun will immediately begin firing once it is full of water. Therefore, the water gun being full of water is also the firing state. The rebound force generated by the first elastic element 3 is greater than the water pressure in the variable volume water storage tank 115. The first elastic element 3 rebounds, applying a rebound force along the first direction X to the pull tube 21, causing the pull tube 21 to move towards the water gun nozzle 111, continuously spraying the water in the variable volume water storage tank 115 through the water gun nozzle 111. Near the end of firing, refer to Figure 4 As shown, the pull-out cylinder 21 abuts against the movable rod 22. The first elastic element 3 continues to apply a rebound force to the pull-out cylinder 21, causing the pull-out cylinder 21 and the movable rod 22 to move together toward the water gun nozzle 111, so that the pull-out cylinder 21 returns to its initial position, all the water in the variable volume water storage tank 115 is sprayed out, and the movable rod 22 closes the water gun nozzle 111, achieving the desired effect. Figure 1 The initial state is shown.

[0102] After completing the entire process from water intake to water spraying, the water gun 10 shoots out a water jet. This is the single-shot mode of the water gun 10. This process keeps the water jet in one piece, the spray distance is long, it is not easy to disperse, the impact force is strong, and it presents a large volume of water bullets with a long-distance launch effect.

[0103] The water gun 10 can also be set to a two-shot mode and a multi-shot mode based on a preset trigger time, that is, to continuously complete two single-shot modes or to continuously complete multiple single-shot modes. For example, when the user triggers the button switch within 1 second, the water gun 10 operates in single-shot mode; when the user triggers the button switch within 1 to 2 seconds, the water gun 10 operates in two-shot mode; and when the user triggers the button switch within 4 to 5 seconds, the water gun 10 operates in five-shot mode.

[0104] It should be noted that the first direction X can be the axial direction of the barrel 1, and the second direction Y can be the radial direction of the barrel 1. The second direction Y intersects with the first direction X, for example, the second direction Y is perpendicular to the first direction X.

[0105] In this example implementation, refer to Figures 1-4As shown, the gun barrel 1 can be configured as a split structure. For example, the gun barrel 1 may include a water spray tube 11 and a fixed tube 12. The fixed tube 12 is connected to the water spray tube 11. The central axis of the fixed tube 12 and the central axis of the water spray tube 11 are located on the same straight line, so that the water spray tube 11 and the fixed tube 12 are connected sequentially in the first direction X.

[0106] The water spray tube 11 has two open ends arranged opposite each other in the first direction X. One of the open ends is configured as a conical nozzle, which is the water gun nozzle 111, so that one end of the tube 1 is configured as the water gun nozzle 111, and the end of the water spray tube 11 away from the fixed tube 12 is the water gun nozzle 111. The conical structure of the end of the water spray tube 11 away from the fixed tube 12 facilitates the configuration of the smaller diameter water gun nozzle 111, sliding area 112, and water passage area 113.

[0107] The fixed cylinder 12 has an open end and a fixed end 122 that are oppositely arranged in the first direction X. The other open end of the water spray tube 11 is inserted into the open end of the fixed cylinder 12 and fixedly connected. The end of the fixed cylinder 12 away from the water spray tube 11 is the fixed end 122, so that the gun barrel 1 has a water gun nozzle 111 and a fixed end 122 that are oppositely arranged. The gun barrel 1 is set as a split structure, which facilitates the installation of the entire water gun 10.

[0108] Of course, in some other exemplary embodiments of this disclosure, the gun barrel 1 can be configured as an integral structure, that is, the water spray barrel 11 and the fixed barrel 12 are integrally molded structures connected together, that is, the water spray barrel 11 and the fixed barrel 12 can be formed by the same manufacturing process; or the water spray barrel 11 and the fixed barrel 12 can be a separate molded structure connected together, that is, the water spray barrel 11 and the fixed barrel 12 can be separately molded and then connected together.

[0109] The nozzle 1 is provided with a sliding zone 112, a water passage zone 113, and a variable-volume water storage tank 115 connected sequentially along the first direction X. Specifically, the sliding zone 112, the water passage zone 113, and the variable-volume water storage tank 115 are all located inside the water spray nozzle 11. The sliding zone 112 is closer to the water gun nozzle 111 than the water passage zone 113, and the water passage zone 113 is closer to the water inlet zone 114 than the sliding zone 112. Specifically, the sliding zone 112 is connected between the water gun nozzle 111 and the water passage zone 113. The variable-volume water storage tank 115 is used to store water. The water in the variable-volume water storage tank 115 can flow through the water passage zone 113 and the sliding zone 112 to the water gun nozzle 111, and then be sprayed out from the water gun nozzle 111.

[0110] A water supply hole 116 is provided on the cylinder wall of the gun barrel 1 in the water inlet area 114. The water supply hole 116 is used to connect the water pump 20. Specifically, a water supply hole 116 is provided on the water spray cylinder 11, and a connecting cylinder 13 is connected to the water supply hole 116. The axial direction of the connecting cylinder 13 can be set perpendicular to the axial direction of the water spray cylinder 11. The connecting cylinder 13 can be connected to the water inlet pipe, and a sealing ring is provided between the connecting cylinder 13 and the water inlet pipe. The sealing ring makes the connection between the connecting cylinder 13 and the water inlet pipe sealed.

[0111] The water supply hole 116 can be used to connect the water pump 20, so that the water pump 20 can pump water from the water source to the water inlet area 114.

[0112] The extending directions of the sliding zone 112 and the water-passing zone 113 are consistent with the axial direction of the water spray pipe 11. The diameter of the water-passing zone 113 can be larger than the diameter of the sliding zone 112; or, the water-passing zone 113 can be set in a conical shape, with the cross-sectional area of ​​the water-passing zone 113 becoming smaller the closer it is to the sliding zone 112; or, a water-passing groove can be provided on the side wall of the water-passing zone 113 so that water can flow through the water-passing zone 113 to the sliding zone 112.

[0113] The diameter of the variable volume water storage tank 115 can be larger than the diameter of the water passage area 113. For example, a step can be set on the inner wall of the water spray tube 11 to form a variable volume water storage tank 115 and a water passage area 113 with different diameters. The step can also restrict the movement of the pull tube 21.

[0114] In some exemplary embodiments of this disclosure, the water gun 10 may further include a positioning part 212a, which is disposed inside the pull tube 21. The positioning part 212a is used to impact the movable rod 22 to achieve the closure of the movable rod 22 on the water gun nozzle 111. (Refer to...) Figure 4 As shown, when the launch is near completion, the positioning part 212a impacts the movable rod 22 under the force of the first elastic member 3 to achieve a seal between the movable rod 22 and the sliding area 112.

[0115] In this example implementation, refer to Figures 1-4 As shown, the pull-out component 2 is disposed inside the gun barrel 1. The pull-out component 2 may include a pull-out cylinder 21 and a movable rod 22 connected along the first direction X, and the movable rod 22 is slidably connected to the pull-out cylinder 21, that is, the movable rod 22 and the pull-out cylinder 21 can slide relative to each other.

[0116] The end of the pull-out tube 21 near the water inlet area 114 is the pull-out end, which is sealed and slidably fitted to the gun barrel 1 to form a variable volume water storage tank 115. The movable rod 22 moves along the first direction X to open or close the water gun nozzle 111.

[0117] It should be noted that the sliding zone 112 and the water-passing zone 113 are always present, while the variable-volume water storage tank 115 is formed by sliding the pull-out end inside the barrel 1. Therefore, in some states, the variable-volume water storage tank 115 may not exist, for example, referring to... Figure 1 In the initial state shown, the variable volume water storage tank 115 does not exist.

[0118] Specifically, the pull-out tube 21 and the gun barrel 1 are arranged on the same central axis. The pull-out tube 21 is located on the side of the water inlet area 114 near the fixed end 122. The end of the pull-out tube 21 near the water inlet area 114 is the pull-out end. The pull-out end is sealed to the gun barrel 1. For example, a first sealing ring 71 can be provided on the outer circumferential surface of the end of the pull-out tube 21 near the variable volume water storage tank 115. The first sealing ring 71 seals the end of the pull-out tube 21 near the variable volume water storage tank 115 to the gun barrel 1, preventing water in the variable volume water storage tank 115 from flowing out of the variable volume water storage tank 115 through the gap between the pull-out tube 21 and the gun barrel 1.

[0119] In some exemplary embodiments of this disclosure, reference is made to Figures 1-4 As shown, the pull-out cylinder 21 may include a first cylinder 211 and a second cylinder 212. The inner wall of the first cylinder 211 is provided with a first stepped structure; specifically, the first cylinder 211 may include a first sub-cylinder and a second sub-cylinder connected sequentially in the first direction X. The inner diameter of the first sub-cylinder is smaller than the inner diameter of the second sub-cylinder, and the outer diameter of the first sub-cylinder is smaller than the outer diameter of the second sub-cylinder; thus, the connection between the first sub-cylinder and the second sub-cylinder of the first cylinder 211 forms a first stepped structure. The first sub-cylinder is coaxially fitted inside the water spray cylinder 11, and the second sub-cylinder is coaxially fitted inside the fixed cylinder 12. The limiting groove 214 may be provided only on the first sub-cylinder.

[0120] At least a portion of the second cylinder 212 is disposed within the first cylinder 211. For example, the entire second cylinder 212 may be disposed within the first cylinder 211, or only a portion of the second cylinder 212 may be disposed within the first cylinder 211. The second cylinder 212 is fixed within the first cylinder 211, and the second cylinder 212 moves together with the first cylinder 211 along the first direction X.

[0121] The second cylinder 212 is provided with a fixed surface. The end of the first elastic member 3 away from the fixed end 122 is fixed to the fixed surface. The second cylinder 212 is a positioning part 212a. That is, the end of the second cylinder 212 near the movable rod 22 impacts the movable rod 22 to make the movable rod 22 close the water gun nozzle 111.

[0122] Specifically, the second cylinder 212 may include a third sub-cylinder and a fourth sub-cylinder connected sequentially in the first direction X. The inner cylinder diameter of the third sub-cylinder is smaller than the inner cylinder diameter of the fourth sub-cylinder, and the outer cylinder diameter of the third sub-cylinder is smaller than the outer cylinder diameter of the fourth sub-cylinder. This results in a second step structure being formed at the connection between the third sub-cylinder and the fourth sub-cylinder of the second cylinder 212, and the step surface of the second step structure forming a fixed surface.

[0123] A portion of the first elastic element 3 extends into the fourth sub-cylinder, which guides the first elastic element 3, preventing it from tilting during compression and extension, thus maintaining its elasticity. The end of the first elastic element 3 furthest from the fixed end 122 is fixed to the fixed surface. At the final moment of water spraying, the first elastic element 3 applies a rebound force to the pull-out cylinder 21, causing the second cylinder 212 to abut against the movable rod 22. Under the action of the rebound force, the movable rod 22 and the second cylinder 212 move towards the water gun nozzle 111, causing the movable rod 22 to close the water gun nozzle 111. The second cylinder 212 can apply a rebound force evenly to the periphery of the movable rod 22, making the force on the movable rod 22 more uniform and preventing tilting due to uneven force, which could lead to the movable rod 22 jamming.

[0124] Of course, in some other example embodiments of this disclosure, the second cylinder 212 may include only the third sub-cylinder and not the fourth sub-cylinder.

[0125] Optionally, a sealing plate 2121 is provided inside the second cylinder 212. The sealing plate 2121 is connected to the inner wall of the second cylinder 212 and is coplanar with the fixed surface, so that a closed structure is formed inside the second cylinder 212. This arrangement makes the area of ​​the fixed surface larger, so as to ensure the connection area and connection effect between the first elastic member 3 and the fixed surface.

[0126] The pull-out end is provided with a through hole 213, the diameter of which is smaller than the diameter of the inner cylinder surface of the pull-out tube 21.

[0127] The movable rod 22 and the pull-out cylinder 21 are arranged on the same central axis, so that the movable rod 22 and the gun barrel 1 are also arranged on the same central axis. The movable rod 22 has a sealing end 223 and a driving end 222 arranged opposite to each other. The sealing end 223 is used to open or close the water gun nozzle 111. The sealing end 223 is slidably disposed in the sliding area 112. When water enters, the sealing end 223 slides from the first position to the second position to open the water gun nozzle 111; when water is sprayed, the sealing end 223 slides from the second position to the first position to open the water gun nozzle 111. The water gun nozzle 111 is closed. For example, a second sealing ring 72 can be provided at the sealing end 223. The second sealing ring 72 seals the connection between the movable rod 22 and the sliding area 112, thereby closing the water gun nozzle 111 and preventing water from flowing through the gap between the movable rod 22 and the sliding area 112 to the water gun nozzle 111, thus affecting the sealing effect of the variable volume water storage tank 115. The second sealing ring 72 moves with the sealing end 223 to the water passage area 113, thereby opening the water gun nozzle 111. The drive end 222 is slidably disposed inside the pull-out cylinder 21.

[0128] That is, the first position can be the position where the sealing end 223 closes the water gun nozzle 111, and the second position can be the position where the sealing end 223 opens the water gun nozzle 111. (Refer to...) Figure 1 The first position is near the water gun nozzle 111, for reference. Figure 3 The second location is near the water passage area 113.

[0129] Moreover, when spraying water, the cross-sectional area of ​​the water passage gap formed by the sealing end 223 and the water passage area 113 is greater than or equal to the cross-sectional area of ​​the water gun nozzle 111, so that the water in the variable volume water storage tank 115 can be squeezed from the water passage gap to the water gun nozzle 111, and the amount of water squeezed out is greater than or equal to the amount of water sprayed out from the water gun nozzle 111, so as to ensure that the water gun 10 can launch the water bullet completely in the firing state.

[0130] Specifically, refer to Figures 1-4 As shown, the movable rod 22 may include a rod portion 221, a driving end 222, and a sealing end 223. The rod portion 221 extends through the through hole 213, from the pull-out cylinder 21 to the through hole 213, and extends into the variable volume water storage tank 115. The driving end 222 is located inside the pull-out cylinder 21 and is connected to the end of the rod portion 221 near the first elastic member 3, that is, the driving end 222 is connected to the end of the rod portion 221 near the fixed end 122. The diameter of the driving end 222 is larger than the diameter of the rod portion 221, so that the pull-out cylinder 21 and the movable rod 22 are slidably connected, so that the movable rod 22 cannot be dislodged from the through hole 213, so that the movable rod 22 is connected to the pull-out cylinder 21, but the movable rod 22 can still move in the first direction X inside the pull-out cylinder 21.

[0131] The drive end 222 may include a positioning disk 2221, a first protrusion 2222, and a second protrusion 2223. The positioning disk 2221 is connected to one end of the rod 221 near the first elastic member 3. The positioning disk 2221 has a first surface and a second surface that are disposed opposite to each other, and a circumferential surface that connects the first surface and the second surface. The first surface is connected to the rod 221 and is disposed perpendicular to the rod 221. The first protrusion 2222 is connected to the circumferential surface of the positioning disk 2221; the second protrusion 2223 is also connected to the circumferential surface of the positioning disk 2221. The second protrusion 2223 is closer to the water gun nozzle 111 than the first protrusion 2222. The second protrusion 2223 and the first protrusion 2222 are opposite to each other and spaced apart in the first direction X, so that there is a gap between the second protrusion 2223 and the first protrusion 2222. The limiting rod 51 can be fitted into the gap between the first protrusion 2222 and the second protrusion 2223 to limit the movable rod 22 and the pull tube 21.

[0132] The edge of the first protrusion 2222 near the second protrusion 2223 can be chamfered, either rounded or beveled; the edge of the first protrusion 2222 away from the second protrusion 2223 can also be chamfered, either rounded or beveled. This allows the limiting rod 51 to slide from the side of the first protrusion 2222 near the second protrusion 2223 to the side of the first protrusion 2222 away from the second protrusion 2223, and vice versa.

[0133] Optionally, refer to Figures 1-4 As shown, the protrusion height of the second protrusion 2223 along the second direction Y is greater than the protrusion height of the first protrusion 2222 along the second direction Y. This arrangement prevents the limiting rod 51 from sliding to the side of the second protrusion 2223 away from the first protrusion 2222.

[0134] In some exemplary embodiments of this disclosure, reference is made to Figures 1-4 As shown, the first elastic element 3 can be a helical spring, a sheet spring, etc.

[0135] In some exemplary embodiments of this disclosure, reference is made to Figures 1-4 As shown, the water gun 10 may also include a limiting structure 5, which is located in the gun barrel 1 and is used to limit the movable rod 22 and the pull tube 21.

[0136] Specifically, refer to Figure 1As shown, a limiting through hole 14 is provided on the cylinder wall of the water spray tube 11 of the gun barrel 1. The gun barrel 1 may include a limiting protrusion 15, which is disposed outside the water spray tube 11. The limiting protrusion 15 is configured as a cavity structure, that is, the limiting protrusion 15 has a receiving cavity. The receiving cavity of the limiting protrusion 15 is connected to the inner cavity of the water spray tube 11 through the limiting through hole 14.

[0137] A limiting groove 214 is provided on the pull-out tube 21. The limiting groove 214 extends along the first direction X of the pull-out tube 21, so that the pull-out tube 21 can move within a set range along the first direction X. That is, the pull-out tube 21 can only move along the first direction X within the range limited by the limiting groove 214.

[0138] The limiting structure 5 may include a limiting rod 51 and a third elastic element 52. The limiting rod 51 passes through the limiting groove 214 into the pull-out tube 21. The third elastic element 52 is connected between the limiting rod 51 and the barrel 1. Specifically, the third elastic element 52 is located in the receiving cavity of the limiting protrusion 15. One end of the third elastic element 52 can be connected to the inner wall of the receiving cavity of the limiting protrusion 15, and the other end of the third elastic element 52 can be connected to one end of the limiting rod 51. The other end of the limiting rod 51 passes through the limiting groove 214 into the pull-out tube 21. The third elastic element 52 may be a coil spring, a spring sheet, etc.

[0139] The end of the limiting rod 51 away from the third elastic member 52 is configured as a tapered structure or a truncated tapered structure, so that the limiting rod 51 can slide from the side of the first protrusion 2222 near the second protrusion 2223 to the side of the first protrusion 2222 away from the second protrusion 2223, or from the side of the first protrusion 2222 away from the second protrusion 2223 to the side of the first protrusion 2222 near the second protrusion 2223.

[0140] Reference Figure 3 and Figure 4 As shown, in the water-filled state and from the start of launch until near the end of launch, the limiting rod 51 is located between the first protrusion 2222 and the second protrusion 2223. (Refer to...) Figure 1 and Figure 2 As shown, before filling with water and after firing, the limiting rod 51 is located on the side of the first protrusion 2222 away from the second protrusion 2223. It should be noted that after firing, it returns to the position shown... Figure 1 The initial state is shown.

[0141] The sliding area 112 has a cross-sectional area along the second direction Y that is larger than the cross-sectional area of ​​the water gun nozzle 111 along the second direction Y, so that the sliding area 112 forms a contact surface with the side wall of the water gun nozzle 111. The contact surface is set as a conical surface, and the closer the contact surface is to the water gun nozzle 111, the smaller the cross-section of the contact surface along the second direction Y. For example, the contact surface can be set as a conical surface or a pyramidal surface.

[0142] The end face of the sealing end 223 near the water gun nozzle 111 can also be configured as a conical surface. Furthermore, the closer this end face is to the water gun nozzle 111, the smaller its cross-section along the second direction Y becomes. For example, if the abutment surface is a conical surface, this end face is also a conical surface; if the abutment surface is a pyramidal surface, this end face is also a pyramidal surface. This ensures that the end face of the sealing end 223 near the water gun nozzle 111 and the abutment surface can achieve a good fit.

[0143] In some exemplary embodiments of this disclosure, the water gun 10 may further include a second elastic element 4 disposed between the sealing end 223 and the water gun nozzle 111. The second elastic element 4 is used to provide a restoring force to the sealing end 223 to open the water gun nozzle 111. The second elastic element 4 may be a coil spring, a spring sheet, etc.

[0144] In some exemplary embodiments of this disclosure, the water gun 10 may further include a water pump 20 connected to the water supply port 116. The water pump 20 may be an integrated electric water pump 20.

[0145] The water pump 20 can be turned on or off by the controller. This design makes the control of the water pump 20 more flexible. For example, the water pump 20 can be turned on after a delay of about 0.3 seconds.

[0146] The specific work process is as follows: Initial state, refer to... Figure 1 As shown, the sealing end 223 of the movable rod 22 is sealed and fitted to the sliding area 112, closing the water gun nozzle 111. The water pump 20 is in the open state, and the water pump 20 draws water to the connecting cylinder 13 and flows to the water inlet area 114. As the water volume in the water inlet area 114 increases, the water pressure will push the pull cylinder 21 to move along the first direction X towards the fixed end 122 to form a variable volume water storage tank 115. At the same time, the pull cylinder 21 will apply pressure to the first elastic element 3, causing the first elastic element 3 to generate a rebound force. Moreover, the movable rod 22 keeps the water gun nozzle 111 closed.

[0147] Water pump 20 operates continuously, refer to Figure 2As shown, the first cylinder 211 of the pull-out cylinder 21 hits the movable rod 22. The water pressure will push the pull-out cylinder 21 and the movable rod 22 to move along the first direction X towards the fixed end 122 until the first protrusion 2222 of the driving end 222 of the movable rod 22 hits the limiting rod 51 and passes over the limiting rod 51 under the action of water pressure. (Refer to...) Figure 3 As shown, a state of full water is formed; at the same time, the water pump 20 changes from the on state to the off state, that is, the water pump 20 stops pumping water.

[0148] Reference Figure 3 As shown, the first elastic element 3 rebounds, firstly pushing the pull tube 21 to move along the first direction X towards the water gun nozzle 111, continuously spraying water from the variable volume water storage tank 115 through the water gun nozzle 111; during this process, under the action of the limiting rod 51, the movable rod 22 cannot move in the first direction X to ensure the smooth flow of water in the water passage area 113. Moreover, the second elastic element 4 provides a certain supporting force for the movable rod 22, preventing the pull tube 21 from driving the movable rod 22 to move during the firing process, and preventing the movable rod 22 from closing the water gun nozzle 111, so as to ensure the smooth progress of the water spraying process.

[0149] Reference Figure 4 As shown, the second cylinder 212 of the final pull-out cylinder 21 impacts the movable rod 22, applying a rebound force in the first direction X to the movable rod 22. This causes the first protrusion 2222 of the driving end 222 of the movable rod 22 to move across the limiting rod 51 towards the water gun nozzle 111, closing the water gun nozzle 111. All the water in the variable-volume water storage tank 115 is then ejected, completing the water spraying process. During this process, the water column remains unified, travels a long distance, is not easily dispersed, has a strong impact, and produces a large volume of water bullets with a long-range launch effect.

[0150] In some exemplary embodiments of this disclosure, reference is made to Figure 1 As shown, a guide groove 121 is provided on the barrel 1. The guide groove 121 extends along the first direction X of the barrel 1. Specifically, a guide groove 121 extending along its first direction X is provided on the fixed cylinder 12.

[0151] A guide block 2111 is provided outside the pull-out tube 21. Specifically, a guide block 2111 is provided outside the first tube 211. The guide block 2111 is slidably engaged with the guide groove 121, that is, the guide block 2111 can slide along the guide groove 121 within the guide groove 121. The guide groove 121 and the guide block 2111 can provide guidance for the sliding of the pull-out tube 21 and can prevent the pull-out tube 21 from rotating inside the gun barrel 1.

[0152] In some exemplary embodiments of this disclosure, reference is made to Figure 1As shown, the water gun 10 may further include a guide rod 6, which is disposed inside the barrel 1. Specifically, the guide rod 6 may be disposed inside the fixed cylinder 12. The length of the guide rod 6 is less than the length of the fixed cylinder 12 in the first direction X, and the length of the guide rod 6 is less than the length of the first elastic member 3 when compressed to its shortest state, so as to avoid the guide rod 6 affecting the compression amount of the first elastic member 3. The axial direction of the guide rod 6 is parallel to the axial direction of the barrel 1, and the guide rod 6 may be arranged with the barrel 1 on the same central axis. One end of the guide rod 6 is fixed to the fixed end 122, and the first elastic member 3 is sleeved on the outside of the guide rod 6. The guide rod 6 can guide the first elastic member 3 to prevent the first elastic member 3 from tilting during compression and rebound.

[0153] In some exemplary embodiments of this disclosure, the water gun 10 may also include a one-way vent valve connected to the water inlet area 114. The one-way vent valve can release the air in the pipe connected to the water inlet area 114, preventing the air in the pipe connected to the water inlet area 114 from flowing to the water gun 10 and preventing the water gun 10 from being unable to take in water.

Figure 5 As shown, the water spraying device may include a water gun 10, a cleaning gun, and a water pump 20; the water gun 10 is any of the water guns described above, and the specific structure of the water gun 10 has been described in detail above, so it will not be repeated here; the cleaning gun has a cleaning nozzle; the water pump 20 is connected to the cleaning gun and the water gun 10; the water pump 20 is used to connect to a water supply source.

The main body 501 may be elongated, and the handle 502 may be U-shaped. One end of the main body 501 has two openings.

[0156] A push-button switch 601 can be installed at the connection point between the handle 502 and the main body 501. The push-button switch 601 and the power switch 602 of the water pump 20 can be positioned opposite each other. The push-button switch can control the power switch 602 of the water pump 20, thereby turning the water pump 20 on or off. The water pump 20 can be an electromechanical integrated electric water pump.

[0157] The cleaning gun may include a connecting tube 301 and a nozzle 302. One end of the connecting tube 301 is connected to the nozzle 302, and the nozzle 302 can extend out of the main body 501 through an opening on the main body 501.

A portion of the water nozzle 111 of the water gun 10 can extend outside the main body 501 through another opening on the main body 501.

[0160] The water pump 20 is used to connect to an external water source, in which case the external water source is the water supply source. Alternatively, the water spraying device may also include a liquid storage tank 80, which is connected to the water pump 20. In this case, the liquid storage tank 80 is the water supply source. The liquid storage tank 80 is also connected to the cleaning nozzle and is used to provide cleaning fluid for the cleaning gun. The liquid storage tank 80 is provided with an air intake structure for air to enter, so as to ensure the air pressure balance inside and outside the liquid storage tank 80, allowing the liquid inside the liquid storage tank 80 to flow out smoothly.

[0161] When the water gun 10 is working, tap water can be stored in the liquid storage tank 80; when the cleaning gun of the water spray device is working, detergent can be stored in the liquid storage tank 80, that is, the liquid storage tank 80 can be used as a foam pot, so that the cleaning gun can realize the cleaning function, such as washing cars, cleaning floors, building exterior surfaces, etc.
