Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, specifically to an optimized shower head shifting structure. Background Technology

[0002] Chinese patent document CN202427567U discloses a hand-operated, multi-functional shower head with adjustable settings, belonging to the field of shower equipment technology. It includes a housing, a water distribution device, a water outlet cover, and a drive device. The water distribution device includes a water distribution plate with fixed inclined teeth. The drive device includes a rotating component and a water-separating plate with a fixed inclined surface and a positioning groove. The rotating component is a gyratory body with movable inclined teeth that mesh with the fixed inclined teeth of the water distribution device, and movable inclined surfaces that adapt to the fixed inclined surface and positioning groove. This utility model utilizes a shower head water distribution switching structure. By pressing a button, water can flow into different inlet chambers on the water outlet cover, thereby realizing the functions of water output, water stoppage, or water pattern change of the shower head. Water distribution switching can be completed with one hand. Users can hold the shower head housing with one hand, freeing their thumb to press the button. The operation is simple and convenient, especially considerate of the elderly and children, making it highly practical and user-friendly.

[0003] The existing multi-speed shower head has the problem that as the water pressure increases, the force required to turn the speed increases, resulting in poor feel when switching speeds and easy jamming during shifting. Therefore, it is necessary to develop an optimized shower head shifting structure. Utility Model Content

[0004] The purpose of this utility model is to provide an optimized shower head shifting structure to solve the problem mentioned in the background art that the force required to rotate the gear increases with the increase of water pressure, resulting in poor feel when shifting gears and easy jamming during shifting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an optimized shower head shifting structure, including a water distribution seat, a base installed on the upper end of the water distribution seat, the water distribution seat and the base being a detachable structure, a ball bearing installed inside the base, and a Phillips head countersunk self-tapping screw installed inside the ball bearing.

[0006] Preferably, the Phillips head countersunk screw presses against the inner ring of the ball bearing through its beveled end face.

[0007] Preferably, the ball bearing is installed by mating with the central protrusion of the water distribution seat.

[0008] Preferably, both the lower surface of the water distribution seat and the upper surface of the base are provided with threaded joints.

[0009] Preferably, the water distribution seat and the base are connected by a snap-fit ​​mechanism.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention uses the beveled end face of the Phillips head countersunk screw to press against the inner ring of the ball bearing. When shifting gears, the base rotates with the outer ring of the bearing. Furthermore, as the water pressure increases, the inner ring of the ball bearing and the Phillips head countersunk screw can offset most of the upward thrust, thus greatly improving the feel of the shower head when shifting gears. It has the advantages of convenient operation, less likelihood of jamming when shifting gears, and smoother and more seamless shifting. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figure 1-3 One embodiment of this utility model is an optimized shower head shifting structure, including a water distribution seat 1, a base 2 installed on the upper end of the water distribution seat 1, the water distribution seat 1 and the base 2 are detachable, a ball bearing 3 is installed inside the base 2, and a cross countersunk self-tapping screw 4 is installed inside the ball bearing 3.

[0018] Furthermore, the Phillips head countersunk screw 4 presses against the inner ring of the ball bearing 3 through its beveled end face. The ball bearing 3 is installed by docking with the central protrusion of the water distribution seat 1. The inner ring of the ball bearing 3 is pressed against by the beveled end face of the Phillips head countersunk screw 4. When shifting gears, the base rotates with the outer ring of the bearing. Secondly, as the water pressure increases, the structure can offset most of the upward thrust through the inner ring of the ball bearing 3 and the Phillips head countersunk screw 4, thereby greatly improving the feel when shifting the shower head gears.

[0019] Furthermore, both the lower surface of the water distribution seat 1 and the upper surface of the base 2 are provided with threaded joints, which have the advantage of convenient connection.

[0020] Furthermore, the water distribution seat 1 and the base 2 are connected by a snap-fit ​​mechanism, which has the advantages of convenient and quick installation and disassembly, making it easy to quickly install, disassemble and repair the water distribution seat 1 and the base 2.

[0021] Working principle: During use, a base 2 is installed on the upper end of the water distribution seat 1. The water distribution seat 1 and the base 2 are detachable. A ball bearing 3 is installed inside the base 2, and a cross-head countersunk self-tapping screw 4 is installed inside the ball bearing 3. The cross-head countersunk self-tapping screw 4 presses the inner ring of the ball bearing 3 through its beveled end face. The ball bearing 3 is connected to the central protruding part of the water distribution seat 1. The beveled end face of the cross-head countersunk self-tapping screw 4 presses the inner ring of the ball bearing 3. When shifting gears, the base rotates with the outer ring of the bearing. Furthermore, as the water pressure increases, the inner ring of the ball bearing 3 and the cross-head countersunk self-tapping screw 4 can offset most of the upward thrust, thus greatly improving the feel of the shower head when shifting gears. It has the advantages of convenient operation, less jamming when shifting gears, and smoother shifting.
