Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention.

[0028] Embodiment

[0029] Combined with Figures 1 to 8This embodiment provides a descaling showerhead that is easy to operate, comprising a showerhead body 1, a water outlet cover 2, a descaling plate 3 and a trigger 4. The showerhead body 1 is provided with a water inlet 5, the water outlet cover 2 is provided with at least one water outlet, and the descaling plate 3 is provided with a descaling needle 6 corresponding to the water outlet. The trigger 4 is movably arranged on the showerhead body 1, and is used to at least select one of the water inlet 5 to switch water out, and synchronously trigger the descaling needle 6 of the descaling plate 3 to insert into or move away from the water outlet.

[0030] The above-mentioned easy-to-operate descaling shower head, by operating the trigger 4, the descaling needle 6 can be inserted into the water outlet to directly remove the scale in the water outlet without disassembling the shower head, thereby simplifying the maintenance process. The trigger 4 is not only used for descaling, but also can switch the water flow between the water inlet 5 and the water outlet to achieve different water outlet effects, thereby increasing the practicality of the shower head. The user only needs to act on the trigger 4 to complete descaling and switch the water outlet, without the need for complicated operations, and is easy to use.

[0031] In this embodiment, the descaling plate 3 is arranged in the cavity of the shower body 1 and can move relative to the water outlet cover 2. The descaling plate 3 is provided with a connecting member 7. The cavity is provided with a corresponding guide member 8 on which the connecting member 7 can be hung and guided. After the relative movement of the guide member 8 and the connecting member 7, the relative position of the descaling plate 3 and the water outlet cover 2 is controlled. Among them, the connecting member 7 is provided on the back of the descaling plate 3, and the cavity of the shower body 1 is provided with a corresponding guide member 8, and the connecting member 7 can move relative to the guide member 8, so as to control the relative position of the descaling plate 3 on the water outlet cover 2, quickly realize the descaling operation and avoid water discharge, and the descaling plate 3 is directly driven to move up and down by the hanging guide of the connecting member 7 by the guide member 8, without the need to add an additional reset structure, which greatly simplifies the effective drive of the descaling plate 3, and the hanging and guiding method makes the drive transmission more efficient and stable.

[0032] In this embodiment, the guide member 8 is arranged on a rotating member 9, and the trigger member 4 is connected to the rotating member 9 in a transmission manner, so as to control the position state of the rotating member 9 and its guide member 8. Specifically, the trigger member 4 is configured as a push button, and the push button is linked to the rotating member 9 through a cam transmission mechanism. When the push button is in the initial position, the rotating member 9 is in a first rotation state, and when the push button is pushed to the working position, the rotating member 9 is in a second rotation state. Therefore, the transmission mechanism is configured in the form of cam transmission, and the corresponding trigger is transmitted to the rotating member 9. The cam transmission can realize a smooth motion conversion.

[0033] like Figures 2 to 5As shown, in this embodiment, the connecting member 7 is configured as a convex post integrally formed on the back surface of the descaling plate 3, the guiding member 8 is configured to be provided on the rotating member 9 and extend obliquely to form an engaging portion of the guide rail 10, and a bayonet 11 adapted to be snap-connected to the guide rail 10 of the engaging portion is provided on the convex post. Preferably, the bayonet 11 is formed with an outwardly expanding notch on one side to facilitate quick sliding and snap connection on the guide rail 10. The bayonet 11 of the convex post is hung on the guide rail 10 of the engaging portion, so that the bayonet 11 is slidably arranged on the guide rail 10, enabling the convex post to move horizontally and obliquely correspondingly to drive the descaling plate 3 to move up and down.

[0034] Among them, the engaging portions are correspondingly formed on the left and right side edges of the rotating member 9, at least two convex posts facing each other on the descaling plate 3 are provided, and the engaging portions and the convex posts are correspondingly matched one by one. Among them, the two convex posts are correspondingly arranged on the peripheral edge of the back surface of the descaling plate 3 to achieve a more stable hanging connection and can efficiently drive and guide the descaling plate 3.

[0035] In this embodiment, the guide rail 10 has a plurality of hanging heights for limiting the convex post at different specified positions, and is suitable for guiding the descaling needle 6 of the descaling plate 3 to insert into or away from the water outlet. Preferably, the guiding member 8 has a low position height for limiting the connecting member 7 at the first position (when the rotating member 9 is in the first rotating state), a middle position height for limiting the connecting member 7 at the second position, and a high position height for limiting the connecting member 7 at the third position (when the rotating member 9 is in the second rotating state). The water outlet surface cover 2 is provided with at least a first water outlet 19 and a second water outlet 20, and when at the low position height, the descaling needle 6 inserts into the first water outlet 19. It should be noted that the above three heights are directly formed on the guiding member 8, and each height corresponds to a relative position state of the connecting member 7 and its descaling plate 3. At the low position height, at this time the descaling plate 3 is at the lower limit position to abut against the water outlet surface cover 2 so that the descaling needle 6 inserts into the first water outlet 19. At the middle position height, at this time the descaling plate 3 moves relatively upward to the middle position (between the water outlet surface cover 2 and the water distribution member 18 below). At the high position height, at this time the descaling plate 3 is at the upper limit position (abutting against the water distribution member 18 below) to be away from the water outlet surface cover 2.

[0036] As Figure 6 and Figure 7 shown, in this embodiment, the push button is connected to a laterally arranged sliding member 12, a rack portion 13 is provided on the sliding member 12, and the cam transmission mechanism includes a rotating tooth 14 meshing with the rack portion 13, a connecting shaft 15 eccentrically arranged on the rotating tooth 14, and a transmission arm 16 pivotally connected between the connecting shaft 15 and the rotating member 9. It should be noted that the sliding member 12 is specifically slidably arranged on the shower handle, and the push button is fixedly connected to the sliding member 12 and arranged on the side facing the user for easy pushing operation.

[0037] The specific transmission work described above is as follows: The user pushes the push button, which drives the sliding member 12 to move along the specified track. The rack portion 13 on the sliding member 12 meshes with the rotating gear 14. The linear motion of the sliding member 12 drives the rotation of the rotating gear 14. The connecting shaft 15 on the rotating gear 14 is eccentrically arranged, and as the rotating gear 14 rotates, it generates an eccentric motion. Furthermore, the connecting shaft 15 transmits this eccentric motion to the rotating member 9 through the transmission arm 16. The transmission arm 16 converts the motion of the connecting shaft 15 into the rotational motion of the rotating member 9, thereby driving the water distribution member 18 to change its position, ultimately switching the water path and realizing different water outlet modes.

[0038] Preferably, the sliding member 12 is laterally arranged below one side of the push button, and the rack portion 13 can move laterally back and forth to drive the rotating gear 14 to rotate back and forth. Thus, the sliding member 12 is laterally arranged below one side of the push button, making the overall structure more compact and saving space. Further, the meshing transmission efficiency between the rack portion 13 and the rotating gear 14 is high, and it can effectively convert the lateral reciprocating motion of the push button into a rotational motion.

[0039] In this embodiment, the rotating gear 14 is rotatably arranged axially outside the rack portion 13. The rotating gear 14 is provided with a half-tooth portion that cooperates with the rack portion 13, and the connecting shaft 15 is configured as an eccentric shaft and is correspondingly arranged on the end face of the gear body on the opposite side of the half-tooth portion. On the one hand, the half-tooth portion can provide more precise control, thereby improving the positioning accuracy. On the other hand, the setting of the eccentric shaft makes the motion more stable and reduces vibration and interference during the transmission process.

[0040] It should be noted that the rotating member 9 and the water distribution member 18 described below are coaxially arranged with each other, and both are controlled by the transmission arm 16 to rotate synchronously, thereby realizing a follow-up setting in which the rotating member 9 and the water distribution member 18 are substantially integrated. In addition, the rotating gear 14 and the rotating member 9 are respectively arranged on different axes. The rotating gear 14 and the rotating member 9 at different axis positions respectively realize rotation during the transmission process. The rotating gear 14 serves as a mid-end connection, while the rotating member 9 serves as the terminal power.

[0041] In this embodiment, the sliding member 12 moves linearly to transmit power to the cam transmission mechanism, and the cam transmission mechanism moves non-linearly relative to the sliding member 12 to transmit power to the rotating member 9. Specifically, the transmission arm 16 and the rotating member 9 are hinged to each other through a hinge shaft and a shaft hole. The transmission arm 16 swings non-linearly and freely between the rotating gear 14 and the rotating member 9 relative to the sliding member 12, making the transmission arm 16 swing flexibly between the rotating gear 14 and the rotating member 9. Correspondingly, the other end of the transmission arm 16 is hinged to the connecting shaft 15 to achieve flexible pivoting at both ends.

[0042] Wherein, when the push button is in the initial position, it drives the transmission arm 16 to swing to the first state. At this time, the rotating member 9 is in the first rotating state, corresponding to the water spray of one of the water outlets (for example, the water spray of the first water outlet 19). When the push button is pushed to the working position, it switches the transmission arm 16 to swing to the second state, and the rotating member 9 is in the second rotating state, corresponding to the water spray of the other water outlet (for example, the granular water of the second water outlet 20). Obviously, in other embodiments, the push button further has another working position for the common water spray of the two water sprays.

[0043] As Figure 8 shown, in this embodiment, the shower head body 1 is provided with an inner shell member 17 forming an internal water passage. The inner shell member 17 has a water distribution cavity communicated with the water inlet 5 and a water distribution member 18 for switching the water outlet of the water distribution cavity. Wherein, the rotating member 9 and the water distribution member 18 are coaxially arranged on the inner shell member 17 and are controlled by the transmission arm 16 to rotate synchronously.

[0044] Specifically, the water outlet face cover 2 is at least provided with a first water outlet 19 and a second water outlet 20. The water distribution cavity is correspondingly provided with a first water outlet hole 21 communicated with the first water outlet 19 and a second water outlet hole 22 communicated with the second water outlet 20. After the water distribution member 18 rotates and switches, it correspondingly selects the first water outlet hole 21 to discharge water, or the second water outlet hole 22 to discharge water, or the first water outlet hole 21 and the second water outlet hole 22 to discharge water simultaneously.

[0045] Obviously, the water distribution member 18 correspondingly blocks the first water outlet hole 21 or the second water outlet hole 22 by rotation to switch the water passage in the water distribution cavity. And when the water distribution member 18 discharges water from the first water outlet hole 21 and the second water outlet hole 22 simultaneously, the water flow entering the first water outlet hole 21 is blocked behind the first water inlet 5 and remains in a non-water-discharging state when the descaling needle 6 is in the lower limit position, or is exposed to the first water outlet 19 and remains in a water-discharging state when the descaling needle 6 is in the middle position. When the descaling needle 6 is in the upper limit position, at this time the water distribution member 18 selects the second water outlet hole 22 to discharge water and the first water outlet hole 21 does not discharge water.

[0046] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention.
