Description

Technical Field

[0001] The embodiments in this application relate to the field of water spraying equipment technology, and in particular to a nozzle structure and a water supply device. Background Technology

[0002] In related technologies, water supply devices can be applied in environments such as agricultural irrigation and equipment cleaning. They can use pipes to connect water sources and nozzle structures, so that the water supply device can spray water within a certain range using the nozzle structure, ensuring stable water supply operation.

[0003] The nozzle structure allows the nozzle body to be plugged into a fixed component, which is then connected to the water supply pipe, thus assembling the nozzle structure within the water supply device. However, during prolonged water spraying operations, the nozzle body can easily loosen and fall off the fixed component. This can cause water to leak out of the fixed component from the water supply pipe, affecting the water pressure within the pipe and reducing the practicality and reliability of the water supply device. Utility Model Content

[0004] This application provides several embodiments of a nozzle structure and a water supply device, aiming to improve the structural design of the nozzle structure, achieve a leak-proof effect, and effectively improve the practicality and reliability of the nozzle structure.

[0005] One embodiment of this application proposes a nozzle structure including a nozzle body, a fixing component, and a water-stop plate. The fixing component has a flow cavity and an inlet and an outlet communicating with the flow cavity. The nozzle body is inserted into the outlet and connected to the fixing component. The water-stop plate is movably disposed within the flow cavity. The nozzle structure has a first state and a second state. In the first state, the water-stop plate avoids opening the outlet; in the second state, the water-stop plate covers the outlet.

[0006] In one embodiment, the waterstop plate is rotatably disposed within the flow cavity in a direction toward or away from the water outlet.

[0007] In one embodiment, the waterstop plate includes a mounting part, a movable part, and a hinge. The mounting part is connected to the inner wall of the flow cavity, and the hinge connects the mounting part and the movable part. The movable part is used to avoid or cover the water outlet.

[0008] In one embodiment, the fixing component is provided with a support member, the support member is connected to the inner wall of the flow cavity, and the waterstop plate abuts against the support member in the first state.

[0009] In one embodiment, the support includes a base and an elastic member. The base is connected to the inner wall of the flow cavity, and the elastic member is connected to the base. The waterstop plate abuts against and compresses the elastic member in the first state.

[0010] In one embodiment, the support member is provided with a supporting inclined surface, and the waterstop plate abuts against the supporting inclined surface in the first state, so that the waterstop plate is inclined relative to the water flow direction in the flow cavity.

[0011] In one embodiment, the waterstop plate has opposing guiding convex surfaces and lateral surfaces, the guiding convex surfaces being disposed on the side of the waterstop plate facing the water outlet.

[0012] In one embodiment, the fixing component includes a magnetic attraction mechanism disposed on the inner wall of the flow cavity, and the waterstop plate is provided with a magnetic element. The magnetic attraction mechanism and the magnetic element can be magnetically attracted together.

[0013] In one embodiment, one end of the nozzle body is positioned to abut against the waterstop plate in the first state.

[0014] In one embodiment, the outer periphery of the nozzle body is provided with a first snap-fit ​​structure, and the inner wall of the water outlet is provided with a second snap-fit ​​structure, wherein the first snap-fit ​​structure and the second snap-fit ​​structure are engaged and snap-fitted together.

[0015] An embodiment of this application also proposes a water supply device, which includes a water supply pipe and a nozzle structure, wherein the nozzle structure is the nozzle structure described above, and the nozzle structure is connected to the water supply pipe.

[0016] In the various embodiments provided in this application, a movable water-stop plate is provided in the flow cavity of the fixed component. When the nozzle structure is in the first state where it can spray water normally, the water-stop plate can avoid opening the water outlet hole, ensuring that the water flow can stably flow from the flow cavity into the water outlet hole and spray water through the nozzle body. At the same time, when the nozzle structure is in the second state where the nozzle body is detached from the fixed component, the water-stop plate can move to cover the water outlet hole, thereby effectively preventing the water flowing into the flow cavity from flowing out of the water outlet hole and avoiding water leakage in the nozzle structure. This allows the nozzle structure to have a certain water-proof function when damaged, which is beneficial to better avoid water accumulation in the installation environment of the water supply device, and better ensure the stability of water pressure in the water supply pipeline, further improving the practicality and reliability of the nozzle structure.

[0030] In related technologies, water supply devices can be applied in environments such as agricultural irrigation and equipment cleaning. They utilize pipes to connect water sources and sprinkler structures, allowing the device to spray water within a certain range and ensure stable water supply operation. The sprinkler structure allows the sprinkler body to be inserted and installed on a fixed component, which is then connected to the water supply pipe, thus assembling the sprinkler structure within the water supply device. However, during prolonged spraying operations, the sprinkler body can easily loosen and fall off the fixed component. This can cause water to leak from the fixed component, affecting the water pressure in the connected pipe and reducing the practicality and reliability of the water supply device. To address these problems, this application proposes a sprinkler structure 100.

[0031] Please see Figures 1 to 7 In one embodiment of this application, the nozzle structure 100 includes a nozzle body 10, a fixing component 30, and a water-stop plate 50. The fixing component 30 has a flow cavity 31 and an inlet hole 33 and an outlet hole 35 connected to the flow cavity 31. The nozzle body 10 is inserted into the outlet hole 35 and connected to the fixing component 30. The water-stop plate 50 is movably disposed in the flow cavity 31. The nozzle structure 100 has a first state and a second state. When the nozzle structure 100 is in the first state, the water-stop plate 50 avoids opening the outlet hole 35; when the nozzle structure 100 is in the second state, the water-stop plate 50 covers the outlet hole 35.

[0032] Understandably, the water supply device can be equipped with a water storage tank or cylinder, and the water stored in the storage tank can be transported to the sprinkler structure 100 for spraying via a water supply pipeline; alternatively, the water supply device can be equipped with a pump, which can be placed in the ambient water source, allowing the pump to draw water from the source and transport it through the water supply pipeline to the sprinkler structure 100 for spraying, thus ensuring the water supply of the water supply device. Furthermore, by controlling the opening and closing of the sprinkler body 10 of the sprinkler structure 100, users can stably obtain water through the sprinkler structure 100, enabling the sprinkler structure 100 to be better applied in scenarios such as irrigation, cleaning, and environmental cooling.

[0033] The nozzle structure 100 can typically adopt a modular design, such as a rocker arm nozzle. By inserting the nozzle body 10 onto the fixing component 30, the fixing component 30 is connected to the water supply pipe. This facilitates the convenient installation of various models of nozzle bodies 10 in the water supply device and allows the nozzle body 10 of the nozzle structure 100 to achieve a more rotatable structure, enabling the nozzle structure 100 to achieve a wider spray range and improve its practicality.

[0034] However, the combined nozzle structure 100 is prone to wear at the connection between the nozzle body 10 and the fixing component 30. Under long-term operation of the nozzle structure 100, the nozzle body 10 may detach from the fixing component 30, causing water in the water supply pipe to leak out from the water outlet 35 of the fixing component 30, and causing a drop in water pressure in the water supply pipe, affecting the stable water supply operation of the water supply device.

[0035] In this application, the water supply device can connect and install the pipe joint on the water supply pipe with the water inlet 33 of the fixed component 30, thereby achieving a stable assembly of the fixed component 30 on the water supply pipe. This allows water flowing in the water supply pipe to flow into the flow chamber 31 through the water inlet 33, and then flow into the nozzle body 10 through the water outlet 35 in the flow chamber 31. The spraying and stopping of the water flow are controlled by the switch of the nozzle body 10. By setting a water stop plate 50 in the flow chamber 31, and allowing the water stop plate 50 to rotate at a certain angle or move horizontally a certain distance in the flow chamber 31, the movement of the water stop plate 50 in the flow chamber 31 can be used to open or close the water outlet 35, thereby avoiding or intercepting the water flow from the flow chamber 31 to the water outlet 35.

[0036] At this time, the state in which the nozzle body 10 is stably connected to the fixing component 30 can be set as the first state of the nozzle structure 100; the state in which the nozzle structure 100 is installed on the water supply pipe and the nozzle body 10 is detached from the fixing component 30 can be set as the second state. When the nozzle structure 100 is in the first state, the water stop plate 50 can move within the flow cavity 31 to a position close to the inner side wall of the flow cavity 31, so that the water stop plate 50 can better prevent water from flowing from the flow cavity 31 into the water outlet 35, ensuring a stable water supply within the nozzle structure 100. When the nozzle body 10 of the nozzle structure 100 detaches from the fixing component 30, the water stop plate 50 can be moved by the linkage structure to cover the water outlet 35; alternatively, an infrared sensor or pressure sensor can be installed between the nozzle body 10 and the water outlet 35, so that when the nozzle body 10 detaches from the water outlet 34 in the second state, the sensor can be triggered to send a control signal, controlling the telescopic mechanism, steering mechanism, or translation mechanism in the flow cavity 31 to move the water stop plate 50, so that the water stop plate 50... Alternatively, the nozzle body 10 can be positioned in the first state by abutting against the water stop plate 50 when inserted into the water outlet 35. Then, when the nozzle body 10 is removed, the limiting structure of the water stop plate 50 can be released, allowing the water flow in the flow cavity 31 to push the water stop plate 50 towards the water outlet 35. This allows the water stop plate 50 to move to the position of the water outlet 35 and cover it, effectively preventing water from flowing from the flow cavity 31 into the water outlet 35, thus achieving the leak-proof function of the nozzle structure 100. Of course, this application is not limited to this. In other embodiments, the water stop plate 50 can also be installed in the flow cavity 31 using other mechanisms, enabling the water stop plate 50 to stably open the water outlet 35 when the nozzle structure 100 is in the first state and stably close the water outlet 35 when the nozzle structure 100 is in the second state. This application does not limit the movement mode of the water stop plate 50 within the flow cavity 31.

[0037] Therefore, by setting a water-stop plate 50 in the flow cavity 31, when the nozzle structure 100 is in the second state where the nozzle body 10 is detached from the fixing component 30, the water-stop plate 50 can stably cover the water outlet 35 to achieve the function of stopping water and preventing leakage. This effectively avoids water leakage at the nozzle structure 100, which could lead to water accumulation in the installation environment. At the same time, it can better prevent the water pressure in the water supply pipeline from being affected, ensuring the stable water supply operation of the water supply device and effectively improving the practicality and reliability of the water supply device. When a user discovers that the nozzle structure 100 is damaged, the fixing component 30 can be removed from the water supply pipe and the nozzle structure 100 can be replaced; or the fixing component 30 can be maintained and a new nozzle body 10 can be installed on the fixing component 30. At the same time, during assembly, the nozzle body 10 can be used to trigger the linkage structure inside the fixing component 30 to drive the water stop plate 50 to move, or the water stop plate 50 can be controlled by the electronic control mechanism to move, so that the water stop plate 50 can stably avoid opening the water outlet 35 when the nozzle structure 100 is adjusted to the first state, ensuring the stable water spraying operation of the nozzle structure 100, and further improving the practicality and reliability of the nozzle structure 100.

[0038] In one embodiment of this application, a movable water-stop plate 50 is provided in the flow cavity 31 of the fixed component 30. When the nozzle structure 100 is in the first state where it can spray water normally, the water-stop plate 50 can avoid opening the water outlet 35, ensuring that the water flow can stably flow from the flow cavity 31 into the water outlet 35 and spray water through the nozzle body 10. At the same time, when the nozzle structure 100 is in the second state where the nozzle body 10 is detached from the fixed component 30, the water-stop plate 50 can move to cover the water outlet 35, thereby effectively preventing the water flowing into the flow cavity 31 from flowing out of the water outlet 35, avoiding water leakage from the nozzle structure 100. This allows the nozzle structure 100 to have a certain water-proof function when damaged, which is beneficial to better avoid water accumulation in the installation environment of the water supply device, and better ensure the stability of water pressure in the water supply pipeline, further improving the practicality and reliability of the nozzle structure 100.

[0039] It is understandable that the nozzle structure 100 can be equipped with a structure within the fixed component 30 that can drive the water-stop plate 50 to slide horizontally. When the nozzle structure 100 is in the first state, the elastic element 373, such as a spring or leaf spring, can be used to compress and drive the water-stop plate 50 to avoid opening the water outlet 35. At this time, a part of the structure on the nozzle body 10 can be used to abut against and fix the elastic element 373, or a telescopic mechanism can be used to limit and fix the elastic element 373, ensuring that the water flow in the flow cavity 31 flows stably through the water outlet 35 to the nozzle body 10. At the same time, when the nozzle structure 100 is in the second state... At this time, the nozzle body 10 separates from the fixed component 30, which can simultaneously release the contact and fixation between the nozzle body 10 and the elastic element 373. Alternatively, the separation of the nozzle body 10 and the fixed component 30 can be detected and the telescopic mechanism can be disengaged from the fixed elastic element 373. This allows the elastic element 373 to recover its elastic deformation and move the water stop plate 50 to the position of the water outlet 35 to cover the water outlet 35, intercepting the water flow from overflowing through the water outlet 35. This effectively prevents the nozzle structure 100 from leaking in the second state and further improves the structural stability and reliability of the nozzle structure 100.

[0040] In addition, see Figure 2 and Figure 7 In one embodiment of this application, the waterstop plate 50 is rotatably disposed in the flow cavity 31 in a direction toward or away from the water outlet 35.

[0041] In this embodiment, the nozzle structure 100 allows the water-stop plate 50 to be rotatably disposed within the flow cavity 31. When the nozzle structure 100 is in the first state, the water-stop plate 50 rotates away from the outlet hole 35 to a position near the inner wall of the flow cavity 31. At this time, a portion of the nozzle body 10 can abut against and limit the water-stop plate 50, or a magnetic attraction mechanism, telescopic mechanism, or other limiting structure provided within the flow cavity 31 can be used to fix the water-stop plate 50, allowing the water-stop plate 50 to avoid opening the outlet hole 35, so that water in the flow cavity 31 can stably flow into the nozzle body 10 through the outlet hole 35. When the nozzle structure 100 is in the second state... In the second state, the nozzle body 10 is separated from the fixing component 30, which can directly release the limiting fixation of the water stop plate 50. Alternatively, the limiting structure can be released by the detection device to detect the state feedback of the nozzle body 10. This allows the water stop plate 50 to rotate in the direction toward the water outlet 35 under the action of the water flow or the pushing mechanism in the flow cavity 31, and to stably cover the water outlet 35. This effectively uses the water stop plate 50 to intercept the water flow to the water outlet 35, preventing water from flowing into the nozzle structure 100 in the second state, and further improving the structural stability and reliability of the nozzle structure 100.

[0042] Furthermore, the structure that allows the water stop plate 50 to be rotatably installed within the flow cavity 31 facilitates the use of water flow in the flow cavity 31 to push the water stop plate 50 when the nozzle structure 100 is in the second state, thus stably covering the water outlet 35. Simultaneously, when the water supply in the water supply pipe is shut off, the water stop plate 50 is not subjected to the pushing force of the water flow. Under the influence of gravity, the water stop plate 50 can rotate away from the water outlet 35 to avoid opening the water outlet 35. This allows the user to reinstall the nozzle body 10 on the fixed component 30, enabling the nozzle structure 100 to re-stabilize in the water supply device. This makes the maintenance of the nozzle structure 100 more convenient and reliable, further improving its practicality and reliability.

[0043] See Figure 2 and Figure 3 In one embodiment of this application, the waterstop plate 50 includes a mounting part 51, a movable part 53 and a hinge 55. The mounting part 51 is connected to the inner wall of the flow cavity 31, and the hinge 55 connects the mounting part 51 and the movable part 53. The movable part 53 is used to avoid or cover the water outlet 35.

[0044] In this embodiment, the waterstop plate 50 may include a mounting part 51, a movable part 53, and a hinge 55. By using a hinge 55 such as a hinge hinge or a hinge shaft to connect the mounting part 51 and the movable part 53, the movable part 53 can be swung relative to the mounting part 51 under the action of the hinge 55. Then, by using the swing of the movable part 53 in the flow cavity 31, the movable part 53 can swing away from the water outlet 35 to avoid opening the water outlet 35, or the movable part 53 can swing towards the water outlet 35 to cover the water outlet 35. This achieves the stable opening and closing effect of the waterstop plate 50 on the water outlet 35, ensuring that the waterstop plate 50 stably covers the water outlet 35 to intercept the water flow in the second state of the nozzle structure 100, and achieving the water-proof performance of the nozzle structure 100 in the second state.

[0045] By connecting the mounting part 51 to the inner wall of the flow cavity 31, the movable part 53 can be spaced a certain distance from the inner wall of the flow cavity 31 under the action of the mounting part 51. This helps to prevent the movable part 53 from sticking to the inner wall of the flow cavity 31, so that the water flow in the flow cavity 31 can flow between the movable part 53 and the inner wall of the flow cavity 31. This is beneficial to better utilize the water flow to drive the movable part 53 to swing when the nozzle structure 100 is in the second state, ensuring the stable sealing of the water stop plate 50 to the water outlet 35, and further improving the structural stability and reliability of the nozzle structure 100.

[0046] See Figure 2 , Figure 5 and Figure 7In one embodiment of this application, the fixing component 30 is provided with a support member 37, which is connected to the inner wall of the flow cavity 31, and the waterstop plate 50 abuts against the support member 37 in the first state.

[0047] In this embodiment, by providing a support member 37 on the inner wall of the flow cavity 31, the support member 37 can be located on the inner side wall of the flow cavity 31. Thus, when the nozzle structure 100 is in the first state, the water-stop plate 50 can abut against the support member 37. This is beneficial for using the support member 37 to separate the water-stop plate 50 and the inner side wall of the flow cavity 31, preventing the water-stop plate 50 from sticking to the inner side wall of the flow cavity 31. There is a certain probability that the water-stop plate 50 will not be able to rotate to cover the water outlet 35 in the second state of the nozzle structure 100. This ensures that the nozzle structure 100 can stably cover the water outlet 35 with the water-stop plate 50 in the second state, thereby achieving the water-proof effect of the nozzle structure 100 and further improving the practicality and structural reliability of the nozzle structure 100.

[0048] In addition, by using the support member 37 to set the waterstop plate 50 and the inner wall of the flow cavity 31 at a certain distance, the water flow can be stably flowed between the waterstop plate 50 and the inner wall of the flow cavity 31, which is conducive to more stably using the water flow to push the waterstop plate 50 toward the water outlet 35, and further improves the structural stability and reliability of the nozzle structure 100.

[0049] See Figure 3 and Figure 7 In one embodiment of this application, the support member 37 includes a seat 371 and an elastic member 373. The seat 371 is connected to the inner wall of the flow cavity 31, and the elastic member 373 is connected to the seat 371. The waterstop plate 50 abuts against and compresses the elastic member 373 in the first state.

[0050] In this embodiment, the support member 37 can be securely connected to the inner wall of the flow cavity 31 using the seat 371. The seat 371 can be a block structure with a certain volume. By providing elastic elements 373 such as springs, leaf springs, and elastic colloids on the side of the seat 371 facing the waterstop plate 50, the waterstop plate 50 can abut against the elastic element 373 when the nozzle structure 100 is in the first state. Under the limiting and fixing effect of the nozzle body 10 or other limiting structures in the flow cavity 31 on the waterstop plate 50, the waterstop plate 50 can be secured. The elastic element 373 can be stably compressed, causing it to undergo a certain elastic deformation. When the nozzle structure 100 is in the second state, the force of the elastic element 373 restoring its elastic deformation can be used to push the water stop plate 50 to rotate in the direction toward the water outlet 35. Under the action of the water flow in the flow cavity 31, the water stop plate 50 can be stably rotated to the position of the water outlet 35 to cover and close the water outlet 35, thus stably achieving the water-proof effect of the nozzle structure 100 and further improving the structural stability and reliability of the nozzle structure 100.

[0051] See Figure 5 In one embodiment of this application, the support member 37 is provided with a support slope, and the waterstop plate 50 abuts against the support slope in the first state so that the waterstop plate 50 is inclined relative to the water flow direction in the flow cavity 31.

[0052] In this embodiment, the support member 37 can be configured as a supporting slope on the side facing the waterstop plate 50. This supporting slope can be inclined relative to the water flow direction from the inlet hole 33 to the outlet hole 35 within the flow cavity 31. When the nozzle structure 100 is in the first state, the waterstop plate 50 can abut against the supporting slope of the support member 37. At this time, the waterstop plate 50 can follow the supporting slope and be inclined relative to the water flow direction within the flow cavity 31. Furthermore, when the nozzle structure 100 is in the second state, the water flow is at the waterstop plate 50. The flow between the water plate 50 and the inner wall of the flow passage 31 allows the force of the water flow on the water stop plate 50 to have a certain component force in the direction of the water outlet 35. This allows the water flow to better drive the water stop plate 50 to rotate toward the water outlet 35, so that the water stop plate 50 can stably cover the water outlet 35, intercepting the water flow in the flow passage 31 from flowing into the water outlet 35. This ensures the leak-proof effect of the nozzle structure 100 in the second state and further improves the structural stability and reliability of the nozzle structure 100.

[0053] See Figure 4 In one embodiment of this application, the waterstop plate 50 has opposing guiding convex surfaces 531 and horizontal surfaces 533, with the guiding convex surfaces 531 located on the side of the waterstop plate 50 facing the water outlet 35.

[0054] In this embodiment, the waterstop plate 50 may have a square boss, an arc boss, or multiple protrusions on the side facing the water outlet 35, so that the side of the waterstop plate 50 can form a flow guiding convex surface 531 structure. At this time, the side of the waterstop plate 50 relative to the flow guiding convex surface 531 can be set as a planar structure, so that the side of the waterstop plate 50 forms a horizontal flow surface 533 structure. Furthermore, when the nozzle structure 100 is in the second state, the water flow is obstructed by the guide convex surface 531, which makes the water flow speed at the horizontal surface 533 of the waterstop plate 50 greater than the water flow speed at the guide convex surface 531 of the waterstop plate 50. This allows the waterstop plate 50 to be subjected to a certain lift force from the horizontal surface 533 to the guide convex surface 531, which is beneficial to better utilize the water flow to push the waterstop plate 50 to rotate in the direction toward the water outlet 35. This allows the waterstop plate 50 to rotate stably to cover the water outlet 35 and intercept the water flow, ensuring the stable water-proof effect of the nozzle structure 100 in the second state, and further improving the structural stability and reliability of the nozzle structure 100.

[0055] In addition, in some other embodiments, the waterstop plate 50 may also be configured with an internal sealed cavity to form a certain floating structure. When the nozzle structure 100 is in the second state, the nozzle structure 100 can release the limiting contact of the waterstop plate 50, or the limiting structure in the flow cavity 31 can release the limiting fixation of the waterstop plate 50. This allows the waterstop plate 50 to rotate stably toward the water outlet 35 under the action of buoyancy, and under the pushing action of the water flow, the waterstop plate 50 can stably cover the water outlet 35, ensuring the stable water-proof effect of the nozzle structure 100 in the second state, and further improving the structural stability and reliability of the nozzle structure 100.

[0056] See Figure 6 In one embodiment of this application, the fixing component 30 includes a magnetic attraction mechanism 39, which is disposed on the inner wall of the flow cavity 31. The water stop plate 50 is provided with a magnetic element 57, and the magnetic attraction mechanism 39 and the magnetic element 57 can be magnetically attracted together.

[0057] In this embodiment, a magnetic attraction mechanism 39 is provided on the inner wall of the flow cavity 31 by the fixing component 30. The magnetic attraction mechanism 39 can be a combination of an electromagnet, a magnet and a translation mechanism, or a combination of a magnet and a rotation mechanism. A magnetic element 57, such as a magnet or a magnetically attractable metal, is provided on the water stop plate 50. When the nozzle structure 100 is in the first state, the magnetic attraction mechanism 39 can control the electromagnet to be energized, or the magnetic attraction mechanism 39 can drive the magnet to move to a position relative to the water stop plate 50. This allows the water stop plate 50 to be close to the inner wall of the flow cavity 31 and can be magnetically attracted by the magnetic attraction mechanism 39 and the magnetic element 57, so that the water stop plate 50 can stably avoid the opening of the water outlet 35. When the nozzle structure 100 is in the second state, the magnetic attraction mechanism 39 can control the electromagnet to be de-energized, or the magnetic attraction mechanism 39 can drive the magnet to move to a position away from the magnetic component, so as to release the magnetic attraction connection between the magnetic attraction mechanism 39 and the magnetic component 57, thereby releasing the limiting fixation of the water stop plate 50 in the flow cavity 31, so that the water stop plate 50 can rotate toward the water outlet 35 to cover the water outlet 35, realizing the water leakage prevention function of the nozzle structure 100, and further improving the stability and reliability of the nozzle structure 100.

[0058] See Figures 2 to 5 In one embodiment of this application, one end of the nozzle body 10 is limited to abutting against the waterstop plate 50 in the first state.

[0059] In this embodiment, the end of the nozzle body 10 inserted at the water outlet 35 may have a partial structure extending into the flow cavity 31. When the nozzle structure 100 is in the first state, the end of the nozzle body 10 can abut against the water stop plate 50, which helps to limit and fix the water stop plate 50 by the nozzle body 10, restricting the water stop plate 50 from moving or rotating to the position of the water outlet 35. This allows the water stop plate 50 to stably avoid opening the water outlet 35, ensuring that the water flow can stably flow from the flow cavity 31 through the water outlet 35 into the nozzle body 10. When the nozzle structure 100 is in the second state, the nozzle body 10 is separated from the fixed component 30, which releases the limiting fixation of the nozzle body 10 on the water stop plate 50. This allows the water stop plate 50 to move more easily within the flow cavity 31 to cover the water outlet 35, achieving a simpler structural design for the nozzle structure 100. There is no need to set up a complex linkage structure or transmission mechanism to drive the water stop plate 50 to move, further improving the practicality and reliability of the nozzle structure 100.

[0060] See Figure 2 , Figure 3 and Figure 7 In one embodiment of this application, the outer periphery of the nozzle body 10 is provided with a first snap-fit ​​structure 11, and the inner wall of the water outlet 35 is provided with a second snap-fit ​​structure 351. The first snap-fit ​​structure 11 and the second snap-fit ​​structure 351 are engaged and snap-fitted together.

[0061] In this embodiment, a first snap-fit ​​structure 11 is provided on the outer periphery of the nozzle structure 100, and a second snap-fit ​​structure 351 is provided on the inner wall of the water outlet 35. The first snap-fit ​​structure 11 and the second snap-fit ​​structure 351 can be protrusions that cooperate and abut against each other in the direction of water flow, or snap-fit ​​grooves and snap-fit ​​protrusions that can be inserted and fixed together. This allows the nozzle structure 100 to be more securely installed on the fixing component 30 under the cooperation and fixing action of the first snap-fit ​​structure 11 and the second snap-fit ​​structure 351, so that the nozzle structure 100 can withstand the impact force of the water flow more stably, and realize more convenient and reliable assembly and installation of the nozzle structure 100 and the fixing component 30, further improving the practicality and reliability of the nozzle structure 100.

[0062] The snap-fit ​​structure between the outer periphery of the nozzle structure 100 and the inner wall of the water outlet 35 allows the nozzle body 10 to rotate more stably on the fixed component 30 when using a rocker arm nozzle or similar structure, ensuring stable operation of the nozzle structure 100. It also facilitates the installation of the water-stopping component within the fixed component 30. If the nozzle body 10 detaches from the fixed component 30 after a period of operation, the water-stopping component can stably cover the water outlet 35, effectively preventing leakage of the nozzle structure 100 in the second state.
