Description

Technical Field

[0001] This utility model relates to the field of water sprayer technology, specifically a telescopic lifting water sprayer. Background Technology

[0002] As an important piece of equipment widely used in many fields, sprinklers exhibit diverse types and design features depending on different application scenarios and functional requirements. In the field of agricultural irrigation, they are a powerful assistant in ensuring the healthy growth of crops. Common types include large sprinkler irrigation machines, which often have a long range and can cover large areas of farmland. Through the rotation or translation of the robotic arm, water is evenly sprinkled onto the field, greatly improving irrigation efficiency and reducing manual labor. There are also underground telescopic sprinklers, where the nozzles are hidden underground during normal times, not affecting surface agricultural operations, and can automatically irrigate during irrigation. Extending out and spraying water precisely saves space and avoids the risk of equipment damage from external forces. In landscaping, exquisitely designed and multifunctional water sprayers are ubiquitous. Small handheld watering cans are popular among gardening enthusiasts because they allow for manual control of water volume and spray direction, carefully caring for each plant. Fixed or mobile water sprayers used in parks, squares, and other large green areas can be set with different spraying modes according to the plant layout. Some spray in a fan shape, while others can achieve 360-degree all-round spraying, ensuring that flowers, trees, and shrubs receive sufficient water nourishment, while also serving as a landscape decoration effect.

[0003] Traditional sprinklers are usually one-piece units in daily life. If the sprinkler is too long, it is inconvenient to store and place, and it is easy to break, so it is not very practical. If the sprinkler is too short, it will be unusable in some specific places. There are many defects and it is not very practical. Therefore, we have proposed a telescopic lifting sprinkler.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a telescopic lifting water sprinkler, which has the following beneficial effects:

[0015] 1. This telescopic lifting water sprayer adopts a three-section telescopic pipe body, which is easy to store. With the two sealing rings of the internal telescopic sealing device, it can effectively ensure the sealing when spraying water and prevent water leakage at the pipe connection point, which would lead to poor water spraying effect. Moreover, the internal structure of the pipe body is simple and stable, and it is highly practical.

[0016] 2. This telescopic lifting water sprayer is equipped with an internal telescopic sealing device. When not in use, the spring of the telescopic sealing device is in a relaxed state, which can keep the three-section tube in a retracted state for easy storage. When the water sprayer is connected to an external high-pressure water source, the water inside the tube will squeeze the three-section tube open, that is, the spring is in a stretched state. After the water spraying is finished, the rebound force of the spring facilitates the retraction of the tube. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7 A telescopic lifting water sprayer includes a pipe body consisting of a main water spray pipe 1, an intermediate telescopic pipe 2, a top telescopic pipe 3, and a bottom component 4, and a telescopic sealing device consisting of a spring component 5, a connecting block 6, a rubber sealing ring 7, and a rubber sealing ring 8. The main body of the pipe body is the main water spray pipe 1, the bottom end of the main water spray pipe 1 is provided with the bottom component 4, and the telescopic sealing device is provided inside the main water spray pipe 1. The main body of the telescopic sealing device is the spring component 5, and the two ends of the spring component 5 are connected to the pipe body through the connecting block 6.

[0027] Furthermore, the bottom end of the main water spray pipe 1 is provided with an external mating thread 11, and the outer cylindrical wall of the main water spray pipe 1 is provided with a connecting pipe 10 corresponding to the end of the external mating thread 11. The connecting pipe 10 communicates with the inside of the main water spray pipe 1, and the axial port of the connecting pipe 10 is machined with a connecting thread. The inner cylindrical wall of the main water spray pipe 1 is provided with two axially symmetrically distributed sliding grooves 12, and the end of the main water spray pipe 1 that is away from the external mating thread 11 is provided with a mating groove 13. The external mating thread 11 facilitates mating connection with the bottom component 4, and this detachable structure facilitates internal cleaning and effectively ensures internal cleanliness.

[0028] Furthermore, the intermediate telescopic tube 2 is provided with a mating block 14 at the shaft end inside the main water spray pipe 1. The mating block 14 is slidably connected to the inner wall of the main water spray pipe 1. The outer cylindrical wall of the mating block 14 is provided with two axisily symmetrically distributed sliders 15. The sliders 15 are slidably connected to the sliding grooves 12. The inner cylindrical wall of the intermediate telescopic tube 2 is provided with axisily symmetrically distributed sliding grooves 16. The end of the intermediate telescopic tube 2 facing away from the mating block 14 is provided with a mating groove 17. The sliders 15 and the sliding grooves 12 slide together, effectively ensuring the stability of the internal telescopic structure.

[0029] Furthermore, the top telescopic tube 3 is provided with a mating block 2 18 at the inner end of the middle telescopic tube 2, and the mating block 2 18 slides with the inner wall of the middle telescopic tube 2. The outer cylindrical wall of the mating block 2 18 is provided with two sliders 2 19 distributed axially, and the sliders 2 19 slide with the groove 2 16. The top telescopic tube 3 is provided with a water spray head 9 at the axial end away from the mating block 2 18. The outer cylindrical wall of the water spray head 9 has a set of water outlet holes 20 distributed in a ring, and the interior of the water spray head 9 is connected with the connecting block 6. The sliders 2 19 and slider 1 15 have the same function and structure, and the two cooperate with each other to effectively ensure the stability of the internal telescopic structure.

[0030] Furthermore, the inner wall of the bottom component 4 corresponding to the main water spray pipe 1 is machined with an internal mating thread 21, which is connected to the external mating thread 11. The bottom of the bottom component 4 is provided with a mating countersunk hole 22, which is connected to the connecting block 6. The connecting block 6 connected inside the bottom component 4 can rotate freely, which effectively ensures the flexibility of the spring component 5 and improves the smoothness of the pipe's contraction and extension.

[0031] Furthermore, the telescopic sealing device consists of two parts: a telescopic structure composed of a spring element 5 and two axisily symmetrically distributed connecting blocks 6, and a sealing structure composed of rubber sealing ring 1 7 and rubber sealing ring 2 8. The two connecting blocks 6 are respectively connected to the interior of the bottom component 4 and the top telescopic tube 3. Rubber sealing ring 1 7 is connected to the mating groove 2 17, and the inner wall of rubber sealing ring 1 7 is connected to the outer wall of the top telescopic tube 3 in a sliding fit. Rubber sealing ring 2 8 is connected to the mating groove 13, and the inner wall of rubber sealing ring 2 8 is connected to the outer wall of the middle telescopic tube 2 in a sliding fit. The sealing structure of the telescopic sealing device effectively prevents dust, impurities and other foreign objects from entering the tube body, avoiding any impact on the subsequent water spraying effect. The combination of the two enhances the sealing of the tube body connection parts, ensuring the cleanliness of the internal environment of the tube body during the shrinkage storage period.

[0032] Working principle: When the telescopic lifting sprinkler is correctly installed according to the diagram, in the absence of use, the spring 5 of the telescopic sealing device is in a relaxed state, playing a crucial role in the contraction drive. Both ends of the spring 5 are securely connected to the bottom component 4 and the top telescopic tube 3 respectively via connecting blocks 6. Due to the natural retraction characteristic of the spring, it generates an inward pulling force on the top telescopic tube 3, causing it to contract. At this time, the mating block 18 on the outer wall of the top telescopic tube 3 and its slider 19 slide inward along the groove 16 on the inner wall of the middle telescopic tube 2, driving the top telescopic tube 3 to retract into the middle telescopic tube 2. Similarly, the mating block 14 on the outer wall of the middle telescopic tube 2 and its slider... 15 slides along the groove 12 on the inner wall of the main water spray pipe 1 into the main water spray pipe 1, eventually causing the entire pipe to retract, greatly saving storage space and solving the problem of inconvenient storage of traditional long water sprayers. At the same time, the rubber sealing ring 7 of the telescopic sealing device fits tightly in the matching groove 2 17, and its inner wall slides in cooperation with the outer wall of the top telescopic pipe 3, effectively preventing dust, impurities and other foreign objects from entering the pipe and avoiding affecting the subsequent water spraying effect; the rubber sealing ring 2 8 is precisely embedded in the matching groove 13 and makes close contact with the outer wall of the middle telescopic pipe 2, further strengthening the sealing of the pipe connection and ensuring the cleanliness of the internal environment of the pipe during the retracted storage period.

[0033] When using the telescopic lifting sprinkler, firstly, tighten the bottom part 4 to the bottom of the main water pipe 1 via the internal thread 21 and the external thread 11 to ensure the pipe structure is stable. Next, connect the connecting pipe 10 to the external high-pressure water source. The high-pressure water flows into the main water pipe 1 through the connecting pipe 10. As the water flow continues, the water pressure gradually increases, and the water flow exerts an outward thrust on the top telescopic pipe 3, overcoming the return force of the spring 5 and pushing the top telescopic pipe 3 to extend. The two-part block 18 and its two-part slider 19 slide smoothly outward along the two-part groove 16, causing the top telescopic pipe 3 to extend out of the middle telescopic pipe 2. At the same time, the middle telescopic pipe 2 is also pushed outward by the water pressure, and the two-part block 14 and the two-part slider 15 slide outward along the two-part groove 12. The main water spray pipe 1 extends, gradually reaching the working state and preparing to spray water. High-pressure water flows continuously through the pipe and is finally sprayed out from a group of outlet holes 20 arranged in a ring on the spray head 9, realizing the water spraying operation. During the water spraying process, the water pressure inside the pipe always maintains an outward pushing force on each telescopic pipe, forming a dynamic balance with the tension force of the spring 5, ensuring that the pipe remains stable in the extended state and guaranteeing the continuity and stability of the water spray. When the water spraying task is completed and the external water source is turned off, the water pressure disappears instantly, and the rebound force of the spring 5 comes into play again, pulling each telescopic pipe to quickly retract back to the initial state, waiting for the next use. Through this ingenious design, the telescopic lifting water sprayer operates efficiently at different stages, combining practicality and convenience.
