Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be arbitrarily combined with each other.

[0050] like Figures 1-17 As shown, this utility model embodiment provides a shower 100 that enables the shower rod to be freely raised and lowered, achieving free height adjustment within a certain range.

[0051] like Figure 1 As shown, the shower 100 of this utility model embodiment includes a shower rod 1, a top spray 2 located at the top water outlet of the shower rod 1, a mounting base 3 located at the bottom of the shower rod 1, a shower head seat 4 located between the top spray 2 and the mounting base 3, and a handheld shower head 5 connected to the mounting base 3 and supported on the shower head seat 4. The top spray 2 and the handheld shower head 5 allow the user to select different bathing modes. The mounting base 3 can be used to install a water inlet device (not shown, such as a temperature control valve or a switching valve) connected to the bottom of the shower rod 1, and also provides a place for the user to place items.

[0052] like Figure 2As shown, the shower rod 1 includes an outer tube 11 and an inner tube 12 sleeved within the outer tube 11. The outer tube 11 includes an outer base tube 111 mounted along the height direction and a lifting outer tube 112. The lifting outer tube 112 is slidably and sealingly fitted with the outer base tube 111 and can maintain a seal with the outer base tube 111 at any position within its lifting range. Similarly, the inner tube 12 includes an inner base tube 121 mounted along the height direction and a lifting inner tube 122. The lifting inner tube 122 is slidably and sealingly fitted with the inner base tube 121 and can maintain a seal with the inner base tube 121 at any position within its lifting range. The arrangement of the outer tube 11 and inner tube 12 of the shower rod 1 allows the shower rod to be freely raised and lowered to a certain height.

[0053] like Figure 1 , Figure 2 As shown, the shower rod 1 of this utility model embodiment also includes a locking device 14 that is connected to the lifting outer tube 112 and slidably sleeved with the outer base tube 111. The locking device 14 allows the lifting outer tube 112 to switch between an active state and a fixed state.

[0054] like Figures 4-8 As shown, the locking device 14 of this embodiment includes a cylindrical body 140, a pair of mounting portions 141a and 141b on opposite outer side walls of the cylindrical body 140, and a pair of locking portions 142a and 142b respectively mounted on the corresponding mounting portions 141a and 141b. The cylindrical body 140 is configured to be slidably fitted onto the shower rod 1.

[0055] like Figure 7 As shown, the mounting parts 141a and 141b are provided with sleeve holes 1423a and 1423b communicating with the inner cavity of the cylinder 140 (see Figure 1423a and 1423b). Figure 7 (Due to the installation of locking rods 1420a and 1420b, they are not fully shown). The locking part 142a includes a pair of locking rods 1420a and 1420b corresponding to a pair of mounting parts 141a and 141b. The pair of locking rods 1420a and 1420b are rotatably fitted with corresponding sleeve holes 1423a and 1423b.

[0056] like Figure 6 As shown, the end faces of the locking rods 1420a and 1420b facing the inner cavity of the cylinder 140 are provided with protrusions 1420-1 and recesses 1420-2 arranged circumferentially along the locking rods 1420a and 1420b. The locking parts 142a and 142b include a locked state in which the protrusions 1420-1 interfere with the outer base tube 111 of the shower rod and lock the shower rod, and an unlocked state in which the recesses 1420-2 adapt to the outer contour of the outer base tube 111 of the shower rod and release the shower rod.

[0057] like Figures 6-8As shown, in this embodiment, the locking rods 1420a and 1420b of the locking parts 142a and 142b extend to the outer wall of the outer base tube 111 of the shower rod 1. When the locking parts 142a and 142b are rotated, the protrusion 1420-1 engages with the outer base tube 111 or the recess 1420-2 engages with the outer base tube 111, so that the locking device 14 can switch between the locked state of locking the outer base tube 111 and the unlocked state of releasing the outer base tube 111, thereby realizing the switching between the movable state and the fixed state of the lifting outer tube 112.

[0058] like Figure 8 As shown, the locking device 14 in this embodiment also includes a soft sleeve 144 provided inside the cylinder 140. The protrusions 1420-1 of the locking rods 1420a and 1240b generate friction with the outer base tube 111 by pressing against the soft sleeve 144, thereby locking the outer base tube 111.

[0059] The locking device 4 of this application embodiment is provided with locking parts 142a and 142b. The locking rods 1420a and 1420b of the locking parts 142a and 1420b are provided with protruding parts 1420-1 and recessed parts 1420-2, which can cooperate with the outer base tube 111 to realize the switching between the locked state of locking the outer base tube 111 and the unlocked state of releasing the outer base tube 111. The structure is simple, the operation is convenient, and it can effectively lock.

[0060] like Figure 6 , Figure 7 As shown, the locking parts 142a and 142b also include a pair of rotating sleeves 1421a and 1421b correspondingly connected to the outer ends of at least one pair of locking rods 1420a and 1420b. The rotating sleeves 1421a and 1421b are rotatably sleeved on the outer side walls of the corresponding mounting parts 141a and 141b. The inner side walls of the rotating sleeves 1421a and 1421b contact the outer side walls of the mounting parts 141a and 141b through soft washers 1422a and 1422b to reduce frictional loss between them. The soft washers 1422a and 1422b are fixedly connected to the rotating sleeves 1421a and 1421b by connecting screws T2.

[0061] like Figure 4 , Figure 5 As shown, the locking device 14 also includes an operating part 143 that connects a pair of locking parts 142a and 142b, allowing the operator to rotate the locking parts 142a and 142b by moving the operating part 143 up and down.

[0062] In this embodiment, the cylinder 140 and the lifting outer tube 112 are assembled separately. The cylinder 140 is sleeved on the outer wall of the outer base tube 111 and the lifting outer tube 112, and is fixedly connected to the lifting outer tube 112, while being slidably sleeved to the outer base tube 111. The locking parts 142a and 142b are fixedly connected to the corresponding mounting parts 141a and 141b by connecting bolts T1. Of course, the cylinder 140 can also be integrally formed with the lifting outer tube 112, which is not limited here.

[0063] When the user needs to adjust the height of the shower rod 1, the user can turn the operating part 143 upwards, causing the locking parts 142a and 142b to rotate synchronously, releasing the pressure on the outer base pipe 111. The user can also raise the lifting outer pipe 112 upwards, which synchronously raises the lifting inner pipe 122 through the adapter pipe 13. When the desired height is reached, the user can turn the operating part 143 again, causing the locking parts 142a and 142b to rotate synchronously and lock the lifting outer pipe 112. Conversely, the operation for lowering the shower rod 1 is similar and will not be described in detail here.

[0064] In this embodiment, both the outer base tube 111 and the inner base tube 121 are straight tubes for easy sliding and lifting. The lifting outer tube 112 is integral and includes a straight tube section 1121 and a bent tube section 1122. The lifting inner tube 122 includes a straight tube section 1221 that is fitted and sealed with the inner base tube 121, and a bent tube section 1222 that extends upward from the straight tube section 1221 and bends. The straight tube section 1221 and the bent tube section 1222 are installed together.

[0065] The straight section 1221 of the lifting inner tube 122 is made of a rigid material (e.g., stainless steel) to enable sliding lifting in conjunction with the inner base tube 121; the bent section 1222 of the lifting inner tube 122 is made of a flexible material (e.g., plastic hose) so that the bent section 1222 can be bent and inserted into the bent section 1122 of the lifting outer tube 112 during installation.

[0066] like Figure 10 As shown, in this embodiment, the outer base tube 111 is sleeved inside the lifting outer tube 112 and includes a sealing end M1 that is sealed to the lifting outer tube 112. One or more sealing rings (not labeled) are installed on the sealing end M1. The lifting inner tube 122 is sleeved inside the inner base tube 121 and includes a sealing end M2 that is sealed to the inner base tube 121. One or more sealing rings (not labeled) are installed on the sealing end M2. The sealing ends M1 and M2 respectively achieve sliding seals with the lifting outer tube 112 and the inner base tube 121.

[0067] like Figure 11 As shown, the shower rod 1 also includes a connecting pipe 13 that connects the lifting outer pipe 112 and the lifting inner pipe 122. The connecting pipe 13 enables the lifting outer pipe 112 and the lifting inner pipe 122 to move up and down synchronously.

[0068] To ensure the continuity of the water supply in the second water supply channel B without interruption by the transfer pipe 13, in this embodiment, the outer wall of the bottom end of the transfer pipe 13 is sealed and fitted with the inner wall of the lifting outer pipe 112, and a first gap G1 is provided between the inner wall of the bottom end of the transfer pipe 13 and the lifting inner pipe 122 for water supply flow; a second gap G2 is provided between the outer wall of the top end of the transfer pipe 13 and the inner wall of the lifting outer pipe 112 for water supply flow, and the inner wall of the top end of the transfer pipe 13 is sealed and fitted with the outer wall of the lifting inner pipe 122. The transfer pipe 13 is also provided with a sleeve hole 130 connecting the first gap G1 and the second gap G2. The transfer pipe 13 also connects the straight pipe section 1221 and the bent pipe section 1222 of the lifting inner pipe 122.

[0069] like Figure 12 As shown, the shower rod 1 is in its initial height state. When the height of the shower rod 1 needs to be adjusted, the outer lifting tube 112 or the inner lifting tube 122 can be adjusted manually or automatically to adjust the shower rod 1 to the predetermined height (see Figure 1). Figure 13 (As shown). It should be noted that: Figure 3 The solid line depicts the shower rod 1 at its initial height, while the dashed line depicts the shower rod 1 in its raised state. In this embodiment, the height of the shower rod 1 is manually adjustable; the user can raise the shower rod 1 by lifting the lifting outer tube 112.

[0070] like Figure 14 As shown, the top spray 2 is provided with a first water outlet channel 21 connected to the water outlet end of the first water supply channel A, and a second water outlet channel 22 connected to the water outlet end of the second water supply channel B. The water outlet panel of the top spray 2 is provided with a plurality of first water outlet holes 23 connected to the first water outlet channel 21, and a plurality of second water outlet holes 24 connected to the second water outlet channel 22.

[0071] like Figures 9-11 As shown, there is an annular gap between the outer pipe 11 and the inner pipe 12. The inner pipe 12 forms a first water supply channel A, and the annular gap between the outer pipe 11 and the inner pipe 12 forms a second water supply channel B. Figure 1 As shown, the mounting base 3 in this embodiment is provided with an operation button 30 for controlling the opening and closing of the first water supply channel A and the second water supply channel B. The operation button 30 is connected to the water inlet device and controls the water inlet device.

[0072] like Figure 14 , Figure 15As shown, the overhead shower 2 is equipped with a universal joint 20 connected to the shower rod 1. The universal joint 20 allows for multi-angle adjustment of the overhead shower 2, thereby enabling multiple different water outlet angles and achieving various water effects. When the angle of the overhead shower 2 needs to be adjusted, the user can directly adjust it by turning the overhead shower 2. The universal joint 20 is equipped with a first distribution channel 201 and a second distribution channel 202 that respectively introduce the first water supply channel A and the second water supply channel B into the first water outlet channel 21 and the second water outlet channel 22.

[0073] The shower rod 1 of this utility model adopts an inner and outer pipe sleeve connection to realize two water channels A and B to supply water to the top spray 2, thereby realizing multiple water output modes of the top spray 2 (see...). Figure 16 This is a water output mode; (refer to...) Figure 17 (This is another water outlet mode). Users can select whether the first water supply channel A and the second water supply channel B can supply water together or separately by adjusting the operation button 30 at the water inlet end of the shower rod 1, thus solving the problem that the existing shower rod 1 top spray water outlet mode is difficult to adjust.
