Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only to represent selected embodiments of the present application.

[0027] EMBODIMENT

[0028] In combination with Figures 1 to 7 , the present embodiment provides a key structure suitable for smooth sliding switching, comprising a press key 1, a key seat 2 and a guide shell 3. The guide shell 3 is used to be attached in an external shell, and the guide shell 3 is provided with an internal slide. The press key 1 and the key seat 2 are arranged in linkage, corresponding to triggering switch switching after operating the press key 1. The key seat 2 is assembled to the internal slide along a preset direction, and the key seat 2 is configured to be guided and moved relative to the internal slide, so as to constrain the press key 1 to be smoothly defined on a specified pressing path.

[0029] The key structure suitable for smooth switching in the above-mentioned, through the guide shell 3 provided with the internal slide and the pressing key 1 linked with the key seat 2, realizes the smooth guidance of the key, the key seat 2 is assembled to the internal slide along the preset direction, and is guided to move relative to the slide, effectively constrains the pressing key 1 and the key seat 2, so that it can only smoothly slide along the specified pressing path, avoids the phenomenon of key deviation or jamming, and ensures the accurate operation and comfortable experience of the key.

[0030] And, through the guiding setting of the key seat 2 and the internal slide, the durability and stability of the key are greatly improved, the wear after long-time use is reduced, and the service life of the product is prolonged, so it is suitable for various water outlet devices, can significantly improve the user experience and reduce the failure rate.

[0031] In the embodiment, the preset direction is configured to be consistent with the pressing path direction of the pressing key 1 and the length direction of the internal slide, further improving the stability and stability of the pressing key 1. Since the guiding moving direction of the key seat 2 is consistent with the pressing path, not only the smooth sliding of the key in the pressing process is ensured, the jamming or deviation phenomenon caused by inconsistent directions is reduced, but also the key can respond more accurately in the pressing process, which helps to improve the accuracy and reliability of the key operation, enhances the operation experience of the user, especially in the equipment that needs to be used for a long time, the fatigue and discomfort can be effectively reduced, and the overall use performance and durability are improved.

[0032] As shown in Figures 2 to 5 In the embodiment, the internal slide is provided in the interior of the guide shell 3, and the key seat 2 is movably arranged on the internal slide in the form of positional insertion. Therefore, the stability and smoothness of the pressing key 1 are greatly improved by the linkage of each structure of the key, so that the key seat 2 can accurately move along the slide direction, avoiding the deviation or jamming caused by the mismatching or inaccurate installation of the key seat 2 and the slide. Especially the smooth sliding of the key seat 2 in the slide ensures that the key can be quickly positioned during pressing, and the response is more accurate, greatly improving the sensitivity and comfort of the user operation.

[0033] In addition, the convenient assembly mode is provided by the movable insertion form, the production process is simplified, the assembly efficiency is improved, the stability of the pressing key 1 can be ensured during use, the failure caused by loose or misaligned parts is reduced, the durability of the product is improved, the service life is prolonged, and the key operation experience of the user is also optimized.

[0034] Preferably, the key seat 2 is in the form of a flat plug structure 4, and the inner slide is provided with a plug hole 5 that is slidingly fitted with the plug structure 4. Through the flat plug structure 4 and the plug hole 5 that is slidingly fitted with the plug structure 4, a more precise and stable connection is further achieved. The plug structure 4 of the key seat 2 is in a matching position with the plug hole 5, so that the key seat 2 can be smoothly guided and slid in the slide, while greatly improving the overall stability. Not only does it ensure smooth movement of the key seat 2 in the slide, but also through the precise fit of the plug and the plug hole 5, the contact stability of the key seat 2 and the slide is enhanced, reducing wear and looseness during long-term use, prolonging the service life of the product. In addition, through the plug-in form between the two, the assembly process is more convenient, saving production and maintenance costs, and improving the overall assembly efficiency.

[0035] As shown in Figure 3 and Figure 4 , in one aspect, the inner side wall of the plug hole 5 is provided with a plurality of first guide ribs 6 extending in a predetermined direction, and the plug structure 4 is in elastic contact with the first guide ribs 6. Through the elastic contact between the plug structure 4 and the first guide ribs 6, the sliding performance and stability of the key seat 2 are effectively improved. The first guide ribs 6 not only play a guiding role to ensure the precise positioning of the key seat 2 in the slide, but also enhance the close fit between the key seat 2 and the plug hole 5 through elastic contact with the plug structure 4, improving the smoothness during key operation and avoiding jamming or sliding difficulty due to looseness or tightness.

[0036] As shown in Figure 3 and Figure 4 , in another aspect, the side wall of the inner slide is correspondingly provided with a plurality of second guide ribs 7 extending in a predetermined direction, and the pressing key 1 and the key seat 2 are at least partially in sliding contact with the second guide ribs 7. Similarly, the second guide ribs 7 have the same effect as the first guide ribs 6 described above. In addition, the first guide ribs 6 and the second guide ribs 7 are arranged in a staggered manner, and are not linearly connected. This improves the multiple close contact of the entire inner slide with the pressing key 1 and the key seat 2.

[0037] It can be understood that the plurality of guide ribs provided can provide appropriate elastic support during the sliding of the key seat 2, so that the key seat 2 will not loosen due to friction after long-term use, thereby improving the durability and stability of the overall key structure. In addition, the elastic contact can also provide a slight buffering effect when the key seat 2 is inserted, reducing the impact and improving the comfort of operation.

[0038] In the embodiment, the pressing key 1 is snap-connected with the key seat 2, and the key seat 2 is lock-connected with the operation end of the external valve core 11. Specifically, a rough pressing contact surface is formed on the outer end side of the pressing key 1, and a snap groove 9 is formed on the inner end side of the pressing key 1. A snap part 8 detachably connected with the snap groove 9 is arranged on one end of the key seat 2, and the other end of the key seat 2 is in the shape of a plug to be fitted into the plug hole 5.

[0039] It can be understood that the key seat 2 is connected with the valve core 11 through the fastener 10, and the key seat 2 triggers the switching of the valve core 11 under the driving of the pressing key 1. Specifically, the switching can be realized by the elastic operation switch of the valve core 11 for one-time pressing, or the switching can be realized by the elastic return of the automatic reset type valve core 11 for pressing reset, which all fall within the protection scope of the present application.

[0040] In the embodiment, the internal slide way of the guide shell 3 can accommodate at least two pressing keys 1 and the key seats 2 corresponding to the pressing keys 1 arranged side by side. Thus, the layout flexibility and space utilization of the key structure are significantly improved, so that multiple pressing keys 1 can be arranged in parallel in the same slide way, and each pressing key 1 and the key seat 2 corresponding to the pressing key 1 can still move independently, ensuring that the operation of each key is not affected by other pressing keys 1, thereby improving the stability and accuracy of the simultaneous operation of multiple keys. The key structure can be applied to devices requiring multiple key operations, and can effectively reduce the interference and jamming problems between keys. Each key maintains a smooth sliding track in the slide way, and the operation is more smooth and rapid.

[0041] In combination with Figure 4 , Figure 6 and Figure 7 , the embodiment further provides a shoulder spray device including a shoulder spray shell 12 and the key structure suitable for stable sliding switching. The shoulder spray shell 12 is provided with a mounting cavity, and the guide shell 3 is correspondingly locked in the mounting cavity. Specifically, the guide shell 3 extends outward along the two lateral sides to form a side wing plate 13, and the screw 14 is locked on the side wing plate 13, and the screw 14 is correspondingly locked in the mounting cavity, so as to improve the stability of the overall structure.

[0042] The side surface of the shoulder spray shell 12 is provided with a hanging part 15 for hanging a spray gun or a shower. The shoulder spray device is provided with a shoulder spray water outlet 16 at the front end side and a lower water outlet 17 at the bottom end side. The lower water outlet 17 is connected with the spray gun or the shower through a hose (not shown in the figure) to be externally connected with the spray gun or the shower for handheld use or placed on the hanging part 15. Preferably, the key structure suitable for stable sliding switching is correspondingly assembled at the front end side of the shoulder spray device and arranged adjacent to the shoulder spray water outlet 16, so as to facilitate the user operation.

[0043] The above are only preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments, and any technical scheme falling within the concept of the present application belongs to the protection scope of the present application.
