Description

Technical Field

[0001] The present application relates to the field of water outlet devices, and in particular to a knob telescopic shower head. Background Art

[0002] In the prior art, the handle length of the handheld shower is fixed and cannot be extended. Therefore, it is particularly not applicable to a shower with a bath scrubbing function, otherwise the back and some parts of the body cannot be scrubbed due to the length of the handle. Summary of the invention

[0003] The purpose of the present application is to overcome the above-mentioned defects or problems existing in the background technology and to provide a knob telescopic shower head, the handle of which can be telescoped and, after being telescoped to the right position, can be locked or unlocked for sliding by operation.

[0004] In order to achieve the above purpose, the following technical solutions are adopted:

[0005] A knob telescopic showerhead, comprising a shower body, the shower body being provided with a water outlet cover and a water inlet pipe extending in a first direction; the shower body also comprising a telescopic sleeve and a knob; the outer wall of the water inlet pipe being provided with a first limiting groove and a second limiting groove along the first direction; the telescopic sleeve being provided outside the water inlet pipe and being adapted to slide and cooperate with the water inlet pipe in a rotationally fixed manner along the first direction; the knob being rotationally connected to the telescopic sleeve about a rotation axis perpendicular to the first direction and being limitedly cooperated with the telescopic sleeve along the rotation axis; the knob being provided with a stopping portion extending toward the water inlet pipe; the stopping portion being limitedly cooperated with the first limiting groove or the second limiting groove when the knob is rotated to the first position to lock the telescopic sleeve from sliding; the stopping portion being disengaged from both the first limiting groove and the second limiting groove when the knob is rotated to the second position to unlock the telescopic sleeve from sliding.

[0006] Furthermore, the water outlet surface cover is provided with bristles extending along the water outlet direction.

[0007] Furthermore, the outer wall of the water inlet pipe is provided with a convex rib extending along a first direction; the convex rib is provided with two notches, respectively forming the first limiting groove and the second limiting groove.

[0008] Furthermore, the outer wall of the water inlet pipe is provided with two pits along the first direction, forming the first limiting groove and the second limiting groove respectively; and the locking portion has telescopic elasticity.

[0009] Furthermore, the locking portion is a spring pin.

[0010] Furthermore, one end of the water inlet pipe close to the water outlet surface cover is provided with a first limit surface facing the telescopic sleeve, and the telescopic sleeve is provided with a second limit surface facing the first limit surface, and when the second limit surface abuts against the first limit surface, the knob can be rotated between the first position and the second position, and when rotated to the first position, the locking portion is limitedly matched with the first limit groove.

[0011] Furthermore, the end of the water inlet pipe away from the water outlet surface cover is provided with a third limit surface facing the telescopic sleeve, and the telescopic sleeve is provided with a fourth limit surface facing the second limit surface. When the fourth limit surface abuts against the third limit surface, the knob can be rotated between the first position and the second position, and when rotated to the first position, the locking portion is limitedly engaged with the second limit groove.

[0012] Furthermore, the water inlet pipe includes a tube body and an end cap, the first limiting groove and the second limiting groove are located on the tube body, the end cap is used for an external water inlet hose, and is fixedly connected to one end of the tube body away from the water outlet cover; the third limiting surface is arranged on the end cap.

[0013] Furthermore, the water inlet pipe also includes a sealing ring, and the outer wall of the end head is provided with a sealing ring groove for accommodating the sealing ring, and the sealing ring abuts against the inner wall of the telescopic sleeve.

[0014] Furthermore, one of the outer wall of the water inlet pipe and the inner wall of the telescopic sleeve is provided with a rotation-stopping rib, and the other is provided with a rotation-stopping groove plugged with the rotation-stopping rib, so as to achieve rotation-stopping cooperation between the telescopic sleeve and the water inlet pipe.

[0015] Compared with the prior art, the above solution has the following beneficial effects:

[0016] The knob drives the locking portion to rotate, so that the locking portion can be switched to cooperate with or disengage from the first limiting groove or the second limiting groove, so that the handle of the knob telescopic shower head can be telescoped, and after being telescoped into place, the telescopic sleeve can be switched to lock or unlock to slide.

[0017] The water outlet cover is provided with bristles, so that the knob-retractable shower head can achieve a bathing function.

[0018] The outer wall of the water inlet pipe is provided with a convex rib, and two notches on the convex rib form a first limiting groove and a second limiting groove, so that the locking part of the knob can be made of a rigid material, which is more convenient to manufacture.

[0019] The outer wall of the water inlet pipe is provided with pits, and the two pits form a first limiting groove and a second limiting groove. In this way, the water inlet pipe is more beautiful when it is exposed from the telescopic sleeve and is not easy to accumulate dirt. However, the locking part of the knob must be made of an object with telescopic elasticity, so the cost is high and the manufacturing is more troublesome.

[0020] The knob can be switched when the two limit surfaces abut against each other, which makes it easier for the user to use.

[0021] By arranging a sealing ring between the water inlet pipe and the telescopic sleeve, the telescopic sleeve can have a damping effect when being extended and retracted, and dirt on the inner wall of the telescopic sleeve can be cleaned more easily. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Embodiment 1

[0043] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 The button telescopic shower head 10 in the first embodiment is shown. Figure 1 and Figure 2As shown, the button telescopic shower head 10 includes a shower head body 1 , a telescopic sleeve 2 and a knob 3 .

[0044] Shower body 1 Figure 3 As shown, it is provided with a water outlet panel 11 located at the water outlet end and a water inlet pipe 12 located at the water inlet end and extending in the first direction. The water outlet panel 11 is provided with bristles 111 extending in the water outlet direction to achieve the function of scrubbing. The water inlet pipe 12 includes a tube body 121, an end 122 and a sealing ring 123. The tube body 121 is provided with a convex rib 1211 extending in the first direction, and the convex rib 1211 is provided with two notches along its length direction, wherein the notch closer to the water outlet panel 11 forms a first limiting groove 1212, and the notch farther away from the water outlet panel 11 forms a second limiting groove 1213; anti-rotation ribs extending in the first direction are also convexly provided on both sides of the tube body 121. A first limiting surface 1215 facing the same extension direction as the tube body 121 is provided at one end of the tube body 121 close to the water outlet surface cover 11. The end 122 is used for externally connecting the water inlet hose, which is fixed to the end of the tube body 121 away from the water outlet cover 11, and its outer wall is provided with a sealing ring groove 1222 for accommodating the sealing ring 123, and it is also provided with a third limiting surface 1221 protruding from the outer wall of the tube body 121 and facing the first limiting surface 1212. The sealing ring 123 is placed in the sealing ring groove 1222 to abut against the inner wall of the telescopic sleeve 2.

[0045] See also Figure 4 and Figure 7 . Telescopic sleeve 2 Figure 4 As shown, a tubular sleeve 21 is provided. The end surface of the sleeve 21 facing the first limiting surface 1215 forms a second limiting surface 25. The outer wall of the sleeve 21 is provided with an annular wall 22 whose axis is perpendicular to the extension direction of the sleeve 21. Three elastic claws 23 are coaxially provided inside the annular wall 22. The elastic claws 23 are provided with outwardly facing protrusions. An arc-shaped rotating hole 24 is provided in the space enclosed by the three elastic claws 23. Figure 7 As shown, the inner wall of the sleeve 21 is formed with a stepped hole, and the stepped surface is located below the annular wall 22 to form a fourth limiting surface 26 facing the third limiting surface 1221. The hole wall of the small hole of the stepped hole is slidably matched with the tube body 121, and the hole wall of the large hole of the stepped hole is slidably matched with the outer wall of the end head 122 through the sealing ring 123. Figure 8 As shown, the inner wall of the sleeve 21 is also formed with a rotation-stopping groove 27 which is plugged into and matched with the rotation-stopping rib 1214 on the tube body 121 of the water inlet pipe 12, thereby forming a rotation-stopping sliding fit between the sleeve 21 and the water inlet pipe 12.

[0046] See also Figure 5 and Figure 6 Knob 3 Figure 5As shown, a knob body 31 is provided. Two marks are provided on the upper surface of the knob body 31, one of which is a lock mark and the other is an unlock mark. An extension ring 33 extending downward is provided on the lower surface of the knob body 31, and an annular groove 34 is provided on the inner wall of the extension ring 33. A stopper 32 is further provided on the lower surface of the knob body 31 in the extension ring 33, and the stopper 32 is a convex block in this embodiment. Figure 7 and Figure 8 As shown, in this embodiment, the elastic claw 23 of the telescopic sleeve 2 is inserted into the slot 34, so that the telescopic sleeve 2 and the knob 3 establish a rotation connection relationship along the axial limit fit of the knob 3, and its rotation axis is perpendicular to the extension direction of the water inlet pipe 12. At this time, the stopper 32 passes through the rotation hole 24 of the telescopic sleeve 2 and extends toward the water inlet pipe 12. As a result, the knob 3 is affected by the rotation limit fit relationship between the stopper 32 and the rotation hole 24, and rotates relative to the telescopic sleeve 2 between the first position and the second position. When the knob 3 is rotated to the first position, the locking mark points to the extension direction of the tube body 121. When the knob 3 is rotated to the second position, the unlocking mark points to the extension direction of the tube body 121.

[0047] The method of using the knob telescopic shower head 10 in this embodiment is as follows:

[0048] Figure 7 The structure of the knob telescopic shower head 10 when it is in a retracted and locked state is shown. Figure 7 As shown, at this time, the first limiting surface 1215 abuts against the second limiting surface 25. At this time, the knob 3 can rotate between the first position and the second position. When the knob 3 is rotated to the first position, the locking portion 32 and the first limiting groove 1212 cooperate to prevent the telescopic sleeve 2 from sliding relative to the water inlet pipe 12.

[0049] To extend the knob telescopic shower head 10, the knob 3 should be rotated to the second position so that the locking portion 32 and the first limiting groove 1212 are in contact with each other. Fig. 9 As shown in the figure, the telescopic sleeve 2 is unlocked and can slide relative to the water inlet pipe 12. During the sliding process, the knob 3 can only stay in the second position due to the obstruction of the rib 1211 and cannot be rotated to the first position. When the telescopic sleeve 2 slides to the point where the fourth limiting surface 26 abuts against the third limiting surface 1221, the knob 3 can be rotated between the first position and the second position. When the knob 3 is rotated to the first position, the stopper 32 and the second limiting groove 1213 are limited and matched, as shown in the figure. Figure 8 As shown, at this time, the telescopic sleeve 2 cannot slide relative to the water inlet pipe 12, and the telescopic sleeve 2 is locked. The knob telescopic shower head 10 can better realize the bathing function at this time.

[0050] In this embodiment, the knob 3 drives the stopper 32 to rotate, so that the stopper 32 can switch to cooperate with or disengage from the first limiting groove 1212 or the second limiting groove 1213, so that the handle of the knob telescopic shower head 10 can be telescopic, and after being telescoped to the right position, the telescopic sleeve 2 can be switched to lock or unlock to slide. In this embodiment, the outer wall of the water inlet pipe 12 is provided with a convex rib 1211, and two notches on the convex rib form the first limiting groove 1212 and the second limiting groove 1213, so that the stopper 32 of the knob 3 can be made of a rigid material, which is more convenient to manufacture. In this embodiment, when the first limiting surface 1215 abuts against the second limiting surface 25 or the third limiting surface 1221 abuts against the fourth limiting surface 26, the knob can be rotated to switch to lock or unlock, which is better and more convenient for the user experience. In this embodiment, by setting a sealing ring 123 between the water inlet pipe 12 and the telescopic sleeve 2, the telescopic sleeve 2 can have a damping effect, and it is also easier to clean the dirt on the inner wall of the telescopic sleeve 2.

[0051] Embodiment 2

[0052] The knob telescopic shower head 10 in the second embodiment is as follows Fig.10 and Fig.11 As shown, there are only two differences compared to the knob telescopic shower head 10 in the first embodiment:

[0053] First, in this embodiment, the outer wall of the tube body 121 has no convex rib 1211, and only two pits are arranged on the outer wall of the tube body 121 along the extension direction of the tube body 121. The pit close to the water outlet panel 11 forms a first limiting groove 1212, and the pit away from the water outlet panel 11 forms a second limiting groove 1213.

[0054] Secondly, in this embodiment, the locking portion 32 of the knob 3 has telescopic elasticity, specifically as follows Fig.11 Spring pin shown.

[0055] When the knob 3 is rotated to the first position, the ball head of the spring pin in the locking portion 32 is locked into the first limiting groove 1212 or the second limiting groove 1213, so that the sliding between the telescopic sleeve 2 and the water inlet pipe 12 is locked. Of course, in order to make this locking more reliable, the groove wall of the first limiting groove 1212 facing the first limiting surface 1215 can be set to be perpendicular to the extension direction of the water inlet pipe 12, and the groove wall of the second limiting groove 1213 facing the third limiting surface 1221 can be set to be perpendicular to the extension direction of the water inlet pipe 12.

[0056] When it is necessary to unlock the limiting cooperation relationship between the locking portion 32 and the first limiting groove 1212 or the second limiting groove 1213, it is only necessary to rotate the knob 3 so that the knob 3 is in the second position relative to the telescopic sleeve 2. When this causes the locking portion 32 to disengage from the first limiting portion 1212 or the second limiting portion 1213, the telescopic sleeve 2 can slide relative to the water inlet pipe 12.

[0057] In this embodiment, since the outer wall of the water inlet pipe 12 has only a pit, the water inlet pipe 12 is more beautiful and less likely to accumulate dirt when it is exposed from the telescopic sleeve 2. However, the locking portion 32 of the knob 3 must be made of an object with telescopic elasticity, so the cost is high and the manufacturing is more troublesome.

[0058] The above specification and description of the embodiments are used to explain the protection scope of the present application, but do not constitute a limitation on the protection scope of the present application.
