[0052] Optionally, the bottom of the inner shell 1 and the water outlet panel 3 can be connected by threaded connection, lock connection, magnetic connection or the like.

[0053] Furthermore, as a preferred embodiment of the present utility model but not a limitation, the bottom of the inner shell 1 and the water outlet panel 3 are connected by a snap-fit ​​connection. The setting of the snap-fit ​​connection makes the connection between the inner shell 1 and the water outlet panel 3 detachable, which is beneficial to the maintenance and cleaning of the device. The user can easily separate the water outlet panel 3 from the inner shell 1 for cleaning or repair without complicated disassembly operations, saving maintenance time and effort.

[0054] Furthermore, a water outlet pipe 8 is provided in the inner shell 1, and the water outlet pipe 8 is connected to the water outlet panel 3. A cylindrical slot 81 is provided at one end of the water outlet pipe 8, and a plug post 32 matching with the slot 81 is provided on the side of the water outlet panel 3 close to the water outlet pipe 8. The slot 81 is plugged and matched with the plug post 32, so that the water outlet pipe 8 is detachably connected to the water outlet panel 3. When the height of the water outlet panel 3 is adjusted in the vertical direction, the water outlet pipe 8 follows the height adjustment of the water outlet panel 3 in the vertical direction.

[0055] like Figures 1 to 10 The bottom of the inner shell 1 shown in the figure extends outwardly away from the water outlet panel 3 to form a limiting portion 12, and a limiting space 13 is provided between the bottom of the outer shell 2 and the limiting portion 12 for the inner shell 1 to drive the water outlet panel 3 to move relative to each other in the vertical direction;

[0056] Furthermore, by forming a limiting portion 12 extending from the bottom of the inner shell 1 and a limiting space 13 between the bottom of the outer shell 2, the limiting space 13 provides a spatial range for the inner shell 1 to move relative to the outer shell in the vertical direction, thereby preventing the water outlet panel 3 from excessive displacement and movement, and helping to ensure that the device maintains stability and reliability during operation.

[0057] Furthermore, the user can adjust the height of the water outlet panel 3 by pulling the limiting portion 12 in the vertical direction without disassembling the entire device, which is conducive to improving the user experience.

[0058] Furthermore, the limiting portion 12 extends outwardly toward the side away from the water outlet panel 3 to form a plate-like structure, and the plate-like structure is convenient for users to grasp, so that users can more conveniently adjust the height of the water outlet panel 3 through the limiting portion 12 .

[0059] like Figures 1 to 10 The adjustment housing 411 is provided with a connection panel 4111, and the top of the inner housing 1 is provided with a connection circular hole 14, and the connection panel 4111 is threadedly connected to the connection circular hole 14, so that the adjustment housing 411 and the inner housing 1 can be detachably connected;

[0060] Optionally, the cross sections of the inner shell 1 and the adjusting shell 411 are both rectangular.

[0061] Furthermore, there are four connecting panels 4111 and four connecting circular holes 14, which are distributed at the four corners of the inner shell 1 and the adjusting shell 411, which is beneficial to improve the stability of the connection between the inner shell 1 and the adjusting shell 411 and prevent the connection part of the device from loosening during use.

[0062] Optionally, the inner shell 1 and the adjustment shell 411 may be connected by snap connection, lock connection, magnetic connection or the like.

[0063] Furthermore, as a preferred embodiment of the present invention but not a limitation, the inner shell 1 and the adjusting shell 411 are connected by a threaded connection. The threaded connection can provide a more stable connection. The threaded structure can increase the friction between the connecting parts, making it more difficult to loosen or fall off.
