Detailed Implementation

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] Reference Figure 1-5 A waterway switching button mechanism, comprising:

[0032] The water distribution body 100 is equipped with a water distribution chamber and several water outlet channels;

[0033] The switching component includes a switching shaft 200, a water distribution mechanism, and a first elastic element. The water distribution mechanism and the first elastic element are disposed in the water distribution cavity. The upper end of the switching shaft 200 extends through the upper wall of the water distribution body 100, and the lower end is connected to the water distribution mechanism and drives the water distribution mechanism to switch the water outlet path. The first elastic element is used for pressing and resetting the switching shaft. In this embodiment, the water distribution mechanism adopts the water distribution plate structure commonly used in the prior art. The water distribution plate rotates and fits in the water distribution cavity. Pressing the switching shaft 200 can drive the water distribution plate to rotate, thereby realizing the switching of the water outlet path. The specific structure is not described in detail here, but can be referred to patent CN115949777A. However, this water distribution mechanism is only an example in this article. This utility model does not limit the structure of the water distribution mechanism, as long as it can realize the switching of the water outlet path by pressing the switching shaft.

[0034] The button assembly includes a button 400 and at least one second elastic member 300. The button 400 is located above the upper wall of the water distribution body 100 and is movably engaged with the water distribution body 100. The upper end of the switching shaft 200 can abut against the button 400. The second elastic member 300 abuts against the upper wall of the water distribution body 100 and the button 400.

[0035] In some embodiments of this utility model, there are two second elastic elements 300, which, together with the switching shaft 200, form a three-point support for the button 400. Initially, the upper end of the switching shaft 200 abuts against the button 400. This three-point support ensures that the button 400 maintains a stable posture during its up-and-down movement, preventing tilting, wobbling, or deviation caused by uneven force. Compared to single-point or two-point support, three-point support effectively counteracts the lateral force generated during the button 400's movement, reducing wear or jamming caused by wobbling. To further ensure the stability of the button 400 during movement, the elastic force of the second elastic elements 300 must be consistent with or nearly consistent with the supporting force on the switching shaft 200 during the button 400's downward movement, preventing uneven force distribution at different positions of the button 400 that could lead to tilting or wobbling.

[0036] In some embodiments of this utility model, the upper wall of the water separator 100 is provided with a first guide post 110, and the second elastic element 300 is a spring, which is sleeved on the outside of the first guide post 110. When the spring is compressed or reset, it is prone to lateral displacement, skewing or twisting due to uneven force. The first guide post 110, by penetrating the inside of the spring, can forcibly constrain the deformation direction of the spring, making it stretch and contract only along the axial direction, avoiding the spring from bulging or bending laterally, ensuring that the elastic force always acts on the button 400 in a preset direction, and guaranteeing the stability and consistency of the pressing feedback.

[0037] In some embodiments of this utility model, a first abutting plane 120 is provided at the lower end of the outer side of the first guide post 110. The first abutting plane 120 is perpendicular to the axis of the first guide post 110, and the lower end of the spring abuts against the first abutting plane 120. The first abutting plane 120 is perpendicular to the axis of the guide post, which can provide a flat and stable support surface for the lower end of the spring, so that when the spring is compressed or reset, the force on the lower end is always parallel to the spring axis, avoiding the spring force deviation caused by the tilt of the support surface, thereby preventing the spring from lateral deformation or tilting, and ensuring that the elastic force is stably transmitted along the axial direction.

[0038] In some embodiments of this utility model, a guide groove 111 is provided on the inner side of the first guide post 110, and a second guide post 460 is provided on the button 400. The second guide post 460 is embedded in the guide groove 111 and can slide along the guide groove 111. The guide groove 111 is coaxial with the first guide post 110. The cooperation between the guide groove 111 and the second guide post 460 forms a clear guiding structure, forcing the button 400 to move only along the extension direction of the guide groove 111.

[0039] In some embodiments of this utility model, the button 400 is provided with an annular rim 410, and the upper end of the spring is located inside the annular rim 410. When the spring is compressed or reset, the upper end is prone to lateral displacement due to the pressure of the button 400 or its own elastic force. The annular rim 410 forms a barrier through its inner wall, which can limit the radial wobble of the upper end of the spring, prevent the spring from slipping off the preset support point of the button 400 or tilting laterally, and ensure that the spring always transmits elastic force axially, maintaining stable support for the button 400.

[0040] In some embodiments of this utility model, the upper wall of the water distribution body 100 is provided with a fastening hole 130, and the button 400 is provided with a buckle 420. The buckle 420 can be inserted into the fastening hole 130 from top to bottom, and the end of the buckle 420 fastens the bottom edge of the fastening hole 130. After the end of the buckle 420 fastens the bottom edge of the fastening hole 130, an axial mechanical limit is formed, which can effectively prevent the button 400 from detaching upward from the water distribution body 100 under the reset elastic force of the second elastic element 300. By adopting the "insertion and fastening from top to bottom" method, no complex positioning structure or tools are required. During assembly, it is only necessary to insert the buckle 420 into the fastening hole 130 and complete the fastening. Compared with the traditional rotating shaft connection method, this fastening structure does not require the reservation of additional installation space, and the connection and movement constraint of the button 400 can be realized within the limited space of the upper wall of the water distribution body 100.

[0041] In some embodiments of this utility model, a housing 500 is also included. The housing 500 has a mounting hole 510. The water separator 100 is disposed within the housing 500. The button 400 is located in the mounting hole 510 and is clearance-fitted with the mounting hole 510. The wall of the mounting hole 510 has a groove 511. The edge of the button 400 has a protrusion 430. A buckle 420 is located on the opposite side of the protrusion 430, and the protrusion 430 is inserted into the groove 511. During installation, the protrusion 430 is first inserted into the groove 511, and then the buckle 420 is aligned with the snap-fit ​​hole 130 to press down the button 400, completing the assembly of the button 400. This utility model achieves the installation of the button 400 through the protrusion 430 at the front end and the buckle 420 at the rear end. These two structures can be installed in existing space without the need for additional structural space, making installation convenient.

[0042] In some embodiments of this utility model, a flange 131 is provided along the edge of the snap-fit ​​hole 130. The button 400 has a second abutting surface 440 and a third abutting surface 450. The second abutting surface 440 is located beside the buckle 420, and the third abutting surface 450 is located beside the second guide post 460. When the button 400 is pressed to the bottom, the flange 131 abuts against the second abutting surface 440, and simultaneously, the upper end of the first guide post 110 abuts against the third abutting surface 450. When pressed to the bottom, the two abutting structures form two-point support, ensuring the stability of the button 400 after it is pressed to the bottom.

[0043] A shower head, including the aforementioned water path switching button mechanism.

[0044] Working principle: When button 400 is pressed down, the spring and switching shaft 200 move downward under pressure. Due to the clearance fit between the inner wall of guide groove 111 and the outer wall of second guide post 460, button 400 tends to move axially and stably along first guide post 110. When button 400 moves to the point where flange 131 abuts against second abutting plane 440, and simultaneously the upper end of first guide post 110 abuts against third abutting plane 450, button 400 reaches its downward limit position and stops moving. During this process, switching shaft 200 also moves downward synchronously to a position where the water path can be switched, realizing water path switching. Subsequently, when the pressure of pressing button 400 is released, due to the elastic force of second elastic element 300, button 400 moves axially along first guide post 110 back to its original position, completing one water path switching of water distribution body 100 by button 400.
