[0025] The utility model discloses a retractable spray pipe. By sliding a first water pipe and a second water pipe relative to each other, the second water inlet is brought close to the first water outlet, and the fitting gap between the first water pipe and the second water pipe is sealed by a sealing component, water is injected into the first water pipe through the first water inlet. While the water flow in the first water pipe is ejected from the outer wall of the first water pipe through the atomizing hole on the first water pipe, it also enters the second water pipe through the first water outlet and the second water inlet and is ejected through the atomizing hole on the second water pipe. By continuing to connect more water pipes such as a third water pipe and a fourth water pipe to the second water pipe in the manner described in this application, the sprayable area of ​​the water mist can be continuously increased, thereby meeting different working conditions.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In an exemplary embodiment of the present disclosure, a retractable spray pipe is provided, such as Figure 1 As shown, Figure 1 is a schematic diagram showing a retractable spray pipe structure according to an exemplary embodiment; Figure 2 is a schematic diagram showing the position of an atomization hole according to an exemplary embodiment; Figure 3is a schematic diagram showing the structure of a sealing assembly according to an exemplary embodiment; Figure 4 According to an exemplary embodiment Figure 2 The middle is an enlarged view of part A showing the position of the lock ring; Figure 5 According to an exemplary embodiment Figure 3 The middle is an enlarged view of part B showing the position of the controller. Figures 1 to 5 Provide explanation.

[0028] Some specific implementation methods described below are intended to facilitate those skilled in the art to understand this embodiment, and this embodiment is not limited to some specific implementation methods described below.

[0029] Reference Figure 1 and Figure 2 An exemplary embodiment of the present disclosure provides a retractable spray pipe, the retractable spray pipe comprising:

[0030] The first water pipe 1 has a first water inlet 11 for connecting to a water source and a first water outlet 12 for draining water. The first water pipe 1 has an atomization hole 4 penetrating through the side wall and communicating with the outside.

[0031] The second water pipe 2 is coaxially slidably connected to the first water pipe 1 and connected to the first water pipe 1 through the first water outlet 12. The second water pipe 2 has a second water inlet 21 for moving in a direction away from the first water inlet 11. The second water pipe 2 has an atomization hole 4 that passes through the side wall and connects to the outside.

[0032] The sealing component 3 is elastic and is filled between the first water pipe 1 and the second water pipe 2. The sealing component 3 is sealed with the inner wall of either the first water pipe 1 or the second water pipe 2. The sealing component 3 is used to fit in a ring shape and press the outer wall of either the first water pipe 1 or the second water pipe 2.

[0033] For example, refer to Figure 2 and Figure 3 The first water pipe 1 and the second water pipe 2 are both long straight tube structures. The second water pipe 2 is sheathed within the first water pipe 1. The first water inlet 11 is always located outside the second water pipe 2, the first water outlet 12 is always located inside the second water pipe 2, and the second water inlet 21 is always located between the first water inlet 11 and the first water outlet 12. The atomization hole 4 penetrates the first and second water pipes 1 and 2 in a direction perpendicular to the length of the first water pipe 1. Under the action of pressure, the water in the first and second water pipes 1 and 2 is sprayed into the outside world through the atomization hole 4 in the form of mist.

[0034] The sealing assembly 3 includes an elastic sealing ring 31 built into the interior of the second water pipe 2, and a locking device 32 that encircles the elastic sealing ring 31 and extends out of the second water pipe 2. The elastic sealing ring 31 is coaxial with the first water pipe 1 and is located inside the second water pipe 2 at the second water inlet 21. The end of the second water pipe 2 at the second water inlet 21 is tapered inward to form a stepped solid structure. This stepped solid structure is used to abut the first water pipe 1 and provide a position limit for the elastic sealing ring 31 in the direction of the second water inlet 21. The outer wall of the end of the elastic sealing ring 31 facing away from the second water inlet 21 is bonded to the second water pipe 2 to form a sealed structure. The locking device 32 is fixed in the middle of the outer wall of the elastic sealing ring 31 and is coaxial with the elastic sealing ring 31. When the locking device 32 is in its natural position, the elastic sealing ring 31 abuts the outer wall of the first water pipe 1. However, the abutting force between the elastic sealing ring 31 and the first water pipe 1 is insufficient to overcome the water pressure within the second water pipe 2 and achieve a seal. At this point, the user can change the length of the first water pipe 1 extending outside the second water pipe 2 by pulling on the first water pipe 1 or the second water pipe 2. Similarly, tightening the locking device 32 squeezes the elastic sealing ring 31 against the outer wall of the first water pipe 1 at the first water outlet 12, forming a seal with the outer wall of the first water pipe 1 at the first water inlet 11 and preventing the second water pipe 2 from moving relative to the first water pipe 1.

[0035] In this embodiment, the first water pipe 1 and the second water pipe 2 are slid relative to each other so that the second water inlet 21 is close to the first water outlet 12, and the fitting gap between the first water pipe 1 and the second water pipe 2 is closed by the sealing assembly 3. Water is injected into the first water pipe 1 through the first water inlet 11. While the water flow inside the first water pipe 1 is ejected from the outer wall of the first water pipe 1 through the atomizing hole 4 on the first water pipe 1, it also enters the second water pipe 2 through the first water outlet 12 and the second water inlet 21 and is ejected through the atomizing hole 4 on the second water pipe 2. By continuing to connect more water pipes such as the third water pipe and the fourth water pipe to the second water pipe 2 in the manner described in this application, the sprayable area of ​​the water mist can be continuously increased, thereby meeting different working conditions.

[0036] In other embodiments, the second water pipe 2 also has a second water outlet 22, which is used to connect other water pipes. For example, the second water outlet 22 is connected to the third water pipe and guides the water in the second water pipe 2 into the third water pipe. Similarly, the second water pipe 2 and the third water pipe are also sealed by the sealing component 3.

[0037] In an exemplary embodiment of the present disclosure, referring to Figure 3 and 4 The locker 32 includes a lock ring 322 that clamps the elastic sealing ring 31 and a controller 321 extending out of the second water pipe 2. The controller 321 is used to pull the lock ring 322 in a direction away from the second water pipe 2.

[0038] For example, refer to Figure 4 and Figure 5 The locking ring 322 has two ends and surrounds the elastic sealing ring 31 in an annular shape. The second water pipe 2 is provided with a through slot 24 that penetrates the side wall of the second water pipe 2 and connects the interior of the second water pipe 2 to the outside world. There are two through slots 24, and the two ends of the locking ring 322 are staggered and inserted into different through slots 24. The second water pipe 2 is provided with a threaded groove 23 that extends from the outer wall of the second water pipe 2 to the interior of the outer wall of the second water pipe 2. The threaded groove 23 extends in the radial direction of the second water pipe 2. There are two threaded grooves 23, each of which is connected to the two through slots 24. The controller 321 is threadedly connected to the threaded grooves 23. The end of the locking ring 322 that extends into the through slot 24 is fixed to the bottom end of the controller 321.

[0039] In this embodiment, the controller 321 is rotated so that the controller 321 can move radially along the second water pipe 2 inside the thread groove 23. For example, when the controller 321 is rotated so that the controller 321 moves toward the outside of the thread groove 23,

[0040] In other embodiments, additional reference Figure 3 The elastic sealing ring 31 has at least two ends, and a controller 321 is fixed to each end of the elastic sealing ring 31 .

[0041] In an exemplary embodiment of the present disclosure, referring to Figure 4 and Figure 5 The elastic sealing ring 31 has a positioning groove 311 for accommodating the locking ring 322 .

[0042] For example, refer to Figure 4 and Figure 5 The positioning groove 311 is recessed from the outer wall of the elastic sealing ring 31 toward the axis of the elastic sealing ring 31, giving the elastic sealing ring 31 a V-shaped cross-section. The locking ring 322 is circumferentially embedded within the positioning groove 311, and the outer edge of the side wall of the locking ring 322 is flush with the opening of the positioning groove 311 in the direction of the side wall of the elastic sealing ring 31. When the controller 321 tightens the locking ring 322, the locking ring 322 presses against the inner wall of the positioning groove 311, compressing the substantial portion of the elastic sealing ring 31 facing the first water pipe 1. This shrinks the elastic sealing ring 31 and increases the pressure between the elastic sealing ring 31 and the first water pipe 1, thereby increasing the friction between the elastic sealing ring 31 and the first water pipe 1 and hindering the first water pipe 1 from moving along the length of the second water pipe 2.

[0043] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
