Description

Technical Field

[0001] This utility model relates to the field of water sprayer technology, and in particular to a water sprayer that automatically switches water spray patterns. Background Technology

[0002] In horticulture, agricultural irrigation, and home garden maintenance, sprinklers are widely used as a common water distribution tool. Traditional sprinklers typically have various water spray patterns, such as mist, jet, and pulse, to meet the irrigation needs of different scenarios.

[0003] Most sprinklers on the market currently use manual adjustment mechanisms, requiring users to rotate, push, pull, or press a switch on the sprinkler to change the spray pattern. While this design is relatively simple in structure, it has significant drawbacks: Inconvenience: Users must physically touch the sprinkler to change the spray pattern, which is extremely inconvenient in large irrigation systems, especially when the sprinkler is installed at a high or difficult-to-reach location. Because the switch is directly integrated into the sprinkler body, users cannot switch the spray pattern remotely, greatly limiting the intelligence and convenience of the irrigation system.

[0004] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a water sprayer that can automatically switch water spray patterns without direct contact with the sprayer.

[0006] This utility model is achieved through the following technical solution:

The water spraying assembly includes a water spraying disc on the main body, and the water spraying disc has a number of different water spraying channels and a number of water spray nozzles that can spray different water sprays. The different water spraying channels are respectively connected to different water spray nozzles.

[0008] The main channel is provided with an annular guide rail cover, and a rotating piston is provided between the guide rail cover and the water spray plate. The rotating piston is provided with a water passage hole, which can be aligned with different water spray channels as the rotating piston rotates. Furthermore, a press-type elastic self-locking structure is provided between the guide rail cover, the rotating piston, and the water spray plate.

[0009] Each time the water source is turned on, the resulting water flow impacts the rotating piston, causing it to rotate at a preset angle, thus automatically switching to the next water splash mode.

[0010] To further address the technical problems addressed by this invention, an automatic water sprayer with switching spray patterns is provided. The push-button elastic self-locking structure includes a return spring between the rotating piston and the spray plate, a first toothed structure around the guide rail cover, a second toothed structure on the outer wall of the rotating piston, and a third toothed structure on the spray plate. The guide rail cover and the spray plate are fixedly connected. The first and second toothed structures form a guide groove, which is composed of several unit grooves connected end-to-end. Each unit groove includes an axial groove and an inclined groove. The two ends of the inclined groove are connected to the upper and lower middle parts of two adjacent axial grooves, respectively. The rotating piston is movably connected between the guide rail cover and the spray plate. The second toothed structure includes several guide teeth that engage in the guide groove. The two sides of each guide tooth are an axial surface and an inclined surface, respectively. The guide teeth can slide unidirectionally along the guide groove as the rotating piston moves axially.

[0011] In order to further solve the technical problem to be solved by this utility model, the present utility model provides an automatic water sprayer with a central column at the center of the rotating piston, a central groove at the center of the spray plate, the central column being inserted into the central groove and being able to rotate and move axially therein, and the return spring being located in the central groove and elastically pressing the central column outward.

[0012] In order to further solve the technical problem to be solved by this utility model, the water sprayer with automatic water spray switching provided by this utility model has several grooves on the side wall of the central groove.

[0013] In order to further solve the technical problem to be solved by this utility model, the present utility model provides an automatic water sprayer with water spraying disc, wherein the spraying disc includes an inner disc and an outer disc fixedly connected together, the spraying channels are all located on the inner disc, and the spray nozzles are all located on the outer disc.

[0014] In order to further solve the technical problem to be solved by this utility model, the present utility model provides an automatic water sprayer with water spraying, wherein a piston gasket that can abut against the spray plate is fixedly connected to the rotating piston, and at least a portion of the piston gasket surrounds the water passage hole.

[0018] In order to further solve the technical problem to be solved by this utility model, the present utility model provides an automatic water sprayer with the number of unit slots being equal to the number of water spray channels, and each unit slot corresponding to a water spray mode switching position.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] This invention provides a sprinkler that automatically switches water spray patterns. Through a push-type elastic self-locking structure (including a return spring, a first toothed structure on the guide rail cover, a second toothed structure on the rotating piston, and a third toothed structure on the spray plate) and a guide groove design, the water flow impact force generated when the water source is turned on acts on the rotating piston, which automatically rotates the rotating piston by a preset angle, thereby switching to the next water spray pattern. The automatic switching of water spray patterns can be achieved by simply controlling the on and off of the water source without the user having to directly contact the sprinkler. This significantly improves the automation level and ease of use of the irrigation system, and is especially suitable for sprinkler applications installed at high places or in hard-to-reach locations.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Please refer to Figures 1 to 6 As shown, this utility model provides a water sprayer with automatic water spray switching. The water sprayer includes a main body 1, and a main channel 11 is provided inside the main body 1. One end of the main channel 11 is provided with a water inlet 111 that can be connected to a water source, and the other end of the main channel 11 is provided with a water spraying assembly. The water spraying assembly includes a water spraying disc 2 detachably connected to the main body 1. The water spraying disc 2 is provided with several different water spraying channels 21 and several water spray nozzles 22 that can spray different water sprays. Each water spraying channel 21 is connected to a corresponding water spray nozzle 22.

[0030] A ring-shaped guide rail cover 3 is provided in the main channel 11, and a rotating piston 4 is provided between the guide rail cover 3 and the water spray plate 2. The rotating piston 4 is provided with a water passage hole 41, which can align with different water spray channels 21 as the rotating piston 4 rotates, thereby changing the water flow path and realizing the switching of different water spray patterns. In addition, a press-type elastic self-locking structure is provided between the guide rail cover 3, the rotating piston 4, and the water spray plate 2. This structure is the core mechanism for realizing the automatic water spray switching function of this utility model.

[0031] The working principle of this invention is as follows: Whenever the water source is turned on, the resulting water flow impacts the rotating piston 4, causing it to rotate by a preset angle (e.g., 60°), thus automatically switching to the next water spray mode. Specifically, when the user turns the water source off and on again, the impact of the water flow causes the rotating piston 4 to complete an automatic switching action under the action of a press-type elastic self-locking structure, achieving a change in water spray pattern without the user directly contacting the sprinkler. This design significantly improves the automation level and ease of use of the irrigation system, and is particularly suitable for sprinklers installed in high or hard-to-reach locations.

[0032] This press-type elastic self-locking structure is designed similarly to the press mechanism on a common automatic ballpoint pen, enabling a cyclical operation of press-lock-press again-release.

[0033] In further detail, the press-type elastic self-locking structure includes a return spring 2c disposed between the rotating piston 4 and the spray plate 2, a first toothed structure 31 disposed around the guide rail cover 3, a second toothed structure 42 disposed on the outer wall of the rotating piston 4, and a third toothed structure 23 disposed on the spray plate 2.

[0034] The guide rail cover 3 and the water spray plate 2 are fixedly connected. The first toothed structure 31 and the second toothed structure 42 form a guide groove 5, which is composed of several unit grooves 51 connected end to end to form a complete annular path. Each unit groove 51 includes an axial groove 511 and an inclined groove 512, with the two ends of the inclined groove 512 connected to the upper and lower middle parts of two adjacent axial grooves 511, respectively. This special groove design allows the guide teeth 421 to move along a predetermined path, thereby achieving precise positioning and switching of the rotary piston 4.

[0035] The rotary piston 4 is movably connected between the guide rail cover 3 and the spray plate 2. The second toothed structure 42 includes a plurality of guide teeth 421, which fit into the guide groove 5. The two sides of the guide teeth 421 are an axial surface 4211 and an inclined surface 4212, respectively. This asymmetrical design ensures that the guide teeth 421 can slide unidirectionally along the guide groove 5 with the axial movement of the rotary piston 4, preventing reverse movement and thus ensuring the unidirectionality and reliability of the water spray switching.

[0036] To improve the stability and accuracy of the rotation of the rotary piston 4, a central column 43 is provided at the center of the rotary piston 4, and a central groove 24 is provided at the center of the water spray plate 2. The central column 43 is inserted into the central groove 24 and can rotate and move axially within it. The return spring 2c is located in the central groove 24 and elastically presses the central column 43 outward, ensuring that the rotary piston 4 can automatically return to its original position after the water flow impact, preparing for the next switching.

[0037] To further reduce the resistance during the movement of the central column 43, several grooves 241 are provided on the side wall of the central groove 24. These grooves 241 have the effect of venting or draining air, avoiding excessive resistance caused by liquid or air pressure during the movement of the central column 43, and improving the sensitivity and reliability of the switching mechanism.

[0038] In terms of structural design, the water spray plate 2 includes an inner plate 2a and an outer plate 2b that are fixedly connected (e.g., by ultrasonic welding). The water spray channels 21 are all located on the inner plate 2a, and the water spray nozzles 22 are all located on the outer plate 2b. This split design facilitates processing and assembly, and also allows for the design of water spray channels and nozzles of different shapes and layouts as needed.

[0039] To ensure no leakage occurs at the connection between the water inlet 41 and the spray channel 21, a piston gasket 6 is fixedly connected to the rotating piston 4, which abuts against the spray plate 2. At least a portion of the piston gasket 6 surrounds the water inlet 41. This sealing design not only improves water resource utilization efficiency but also ensures precise control of the water spray pattern.

[0040] In terms of practicality, a water inlet pipe 7 is detachably connected to the water inlet 111 of the main body 1, and a quick connector 8 is provided at the water inlet pipe 7. This design allows users to quickly connect or disconnect the water source according to actual usage scenarios, improving the product's practicality and flexibility. Meanwhile, a base 9 is detachably connected to the main body 1, enabling the water sprayer to be stably mounted on the work platform, meeting the usage needs of different scenarios.

[0041] To optimize the water flow path and improve the water spray effect, the shape of the water passage 41 is matched with the inlet shape of the water spray channel 21 (e.g., fan-shaped) to ensure that the water flow can smoothly transition when switching channels, reduce energy loss, and improve the water spray effect.

[0042] To achieve precise water spray mode switching, the number of unit slots 51 is equal to the number of water spray channels 21 (in this embodiment, both are 6), and each unit slot 51 corresponds to a water spray mode switching position. This one-to-one correspondence design ensures that the water sprayer can accurately switch to the next preset water spray mode each time the water source is turned on, realizing a complete cyclic switching function.

[0043] Through the aforementioned structure and working principle, this utility model's sprinkler can achieve water spray pattern switching without direct contact with the sprinkler body. Users can indirectly achieve automatic water spray pattern switching simply by controlling the on / off state of the water supply. This design significantly improves the automation level and ease of use of the irrigation system, and is especially suitable for application scenarios that are difficult to operate directly, such as sprinklers installed at heights, large irrigation systems, or environments that require frequent switching of water spray patterns.

[0044] This sprinkler's control function overcomes distance limitations. For example, in large farms and gardens, operators no longer need to frequently travel to and from the sprinkler area. They can remotely control the water supply switch to switch water spray patterns and adjust the spray mode as needed, saving significant time and effort and greatly improving work efficiency. This sprinkler also provides new ideas for technological development in related industries. The product can be paired with a smart WiFi-controlled water valve, allowing users to change the spraying area by setting the valve's on / off state, thus driving the sprinkler industry towards intelligent and multifunctional development.

[0046] Based on the above embodiments, those skilled in the art can make some modifications and improvements to this utility model according to actual needs, for example:

[0047] 1. The number, shape, and layout of the water spray channels 21 and water nozzles 22 can be changed to achieve more diverse water spray effects;

[0048] 2. The design of the guide groove 5 can be adjusted to change the switching angle step value, thereby achieving finer or coarser water splash switching;

[0049] These modifications and improvements all fall within the protection scope of this utility model.

Various modifications and variations can be made to this utility model by those skilled in the art.
