In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0056] like Figures 1 to 16As shown, the present application provides a circulation switching shower, the circulation switching shower 100 includes a water channel body 1, a water channel switching mechanism 2 and a front switching mechanism 3, the water channel body 1 has a first water channel 11 and a plurality of second water channels 12; the water channel switching mechanism 2 is provided with a control component 21 and a water diversion member 22, the water diversion member 22 is provided with a water diversion port 221, the water diversion member 22 is arranged on the water channel body 1, the control component 21 drives the water diversion member 22 to switch relative to the water channel body 1, so that the water diversion port 221 is selectively switched to connect to the inlet of the second water channel 12; the front switching mechanism 3 includes a front body 31 and a switching component 32, the front body 31 and the switching component 32 are connected to the front body 31, and the front body 31 and the switching component 32 are connected to the front body 31. The front body 31 has a water inlet 312 and a first front outlet 313 and a second front outlet 314 connected to the water inlet 312, the first front outlet 313 is connected to the water diversion port 221, and the second front outlet 314 is connected to the inlet of the first waterway 11; the switching component 32 is arranged on the front body 31, and the switching component 32 has a first state in which water flows through the first front outlet 313 or a second state in which water flows through the second front outlet 314. After the switching component 32 is switched to the first state, it can maintain the first state under the action of water pressure, and the switching component 32 switches from the first state to the second state when the water pressure is lost.

[0057] The above-mentioned circulation switching shower 100 has a water distribution member 22 and a plurality of second water channels 12 on the water channel body 1. Based on this, different water outlet components can be placed on each second water channel 12 to form different water outlet modes. The water channel body 1 is also provided with a first water channel 11, and different water outlet components can also be placed on the first water channel 11. The switching component 32 on the front switching mechanism 3 can make the water flow through the first front outlet 313 and the second front outlet 314. In the second state, the switching component 32 makes the water flow through the second front outlet 314 and directly flow out through the first water channel 11. This state can be set as the default initial state. In the water outlet state, when the switching component 32 is switched to the first state, water flows through the first front outlet 313 into the water diversion port 221 and then flows out through the second water channel 12. At this time, a different water outlet mode is selected, and the switching component 32 remains in the first state due to the water pressure. After the water is turned off, the water pressure disappears, and the switching component 32 switches from the first state to the second state, returning to the initial water outlet state in which water can flow through the second front outlet 314 to the first water channel 11. When used again, it is still in this state. Therefore, the above-mentioned cyclic switching shower head 100 can ensure the fixed water outlet mode at the beginning of use, thereby improving the user experience.

[0058] The circulation switching shower head 100 has a housing 6, the housing 6 has an inner cavity, and the water channel body 1, the water distribution member 22 and the front body 31 are located in the inner cavity of the housing 6. In the current embodiment, the water distribution member 22 is a water distribution plate.

[0059] It should be noted here that the number of the second water channels 12 is not specifically limited. In the current embodiment, three second water channels 12 are provided, and different water outlet components are provided in each water channel, such as a component capable of producing soft mist water, a component capable of producing blade water, a component capable of producing gathered water, etc., so that different water outlet modes are formed according to different components. The first water channel 11 is provided with a component for producing bubble water. In some alternative embodiments, four second water channels 12 are provided, each of which is provided with the above-mentioned water outlet components, and the outlet of the first water channel 11 is connected to one of the second water channels 12, and the interface between the two is located between the inlet and outlet of the second water channel 12, that is, the water flows through the first water channel 11 through the second water channel 12, so that when the water channel is switched, all water outlet forms can be covered.

[0060] In some embodiments, the control component 21 can drive the water distribution element 22 to switch in one direction or two directions in sequence, so that the water distribution element 22 rotates in one direction or two directions, so that different water channels can be switched in one direction or two directions; using two-way switching can avoid the path of a single switch becoming longer.

[0061] like Figure 3 , Figure 4 and Figure 7 As shown, in some embodiments, a water diversion chamber 13 is provided on the water channel body 1, and the water diversion chamber 13 has a water chamber inlet 131, and the water chamber inlet 131 is connected to the first front outlet 313, so that water flows into the water diversion chamber 13 through the first front outlet 313, and the inlets of multiple second water channels 12 are distributed circumferentially in the water diversion chamber 13, and the water diversion member 22 is rotatably arranged in the water diversion chamber 13, and the control component 21 is connected to the water diversion member 22, so that when the water channel is switched, the control component 21 drives the water diversion member 22 to rotate, so that the water diversion port 221 on the water diversion member 22 can select one of the circumferentially distributed inlets of the second water channels 12.

[0062] In some embodiments, the water channel body 1 can be integrally formed with the front body 31 , so that the water cavity inlet 131 is connected to the first front outlet 313 , and the second front outlet 314 is connected to the inlet of the first water channel 11 .

[0063] Specifically, Figures 8 to 11As shown, the control assembly 21 includes a ratchet 211, a ratchet member 212, a first rotating shaft 216 and a waterway control key 213, wherein a through hole is provided on the water diversion chamber 13, the first rotating shaft 216 is provided in the water diversion chamber 13 and one end of the first rotating shaft 216 is connected to the water diversion member 22, and the other end is sealed and passes through the through hole to be connected to the ratchet 211, so that the two-way rotation of the water diversion member 22 is driven by the two-way rotation of the ratchet 211. In the current embodiment, the ratchet 211 is provided with a first ratchet tooth 2111 and a second ratchet tooth 2112, and the first ratchet tooth 2111 and the second ratchet tooth 2112 are both distributed on the outer peripheral surface of the ratchet 211 along the circumference of the ratchet 211, and the first ratchet tooth 2111 and the second ratchet tooth 2112 are in opposite directions. The pawl member 212 is connected to the water channel body 1, and the pawl member 212 has two opposite pawls 2121. The two pawls 2121 can respectively abut against the first ratchet tooth 2111 and the second ratchet tooth 2112 for limiting, and the water channel control key 213 is connected to the pawl member 212, so that when force is applied to the water channel control key 213, the pawl member 212 can be rotated relative to the water channel body 1, so that one of the pawls 2121 disengages from the ratchet 211, and the other pawl 2121 pushes the ratchet 211 to rotate forward; and when reverse force is applied, the ratchet 211 will be driven to rotate reversely, realizing two-way cycle switching.

[0064] In some other embodiments, the control assembly 21 may include a one-way ratchet (not shown in the figure), that is, the one-way ratchet has only one one-way ratchet tooth, so that only one-way cyclic switching can be performed.

[0065] A second elastic member 214 is also provided between the pawl member 212 and the waterway body 1, so that the pawl 2121 can rotate relative to the waterway body 1, and when no force is applied to the waterway control key 213, the two pawls 2121 can be quickly reset to ensure the state of the limited contact with the ratchet wheel 211, and ensure stability after switching. It can be understood that the form of the waterway control key 213 is not specifically limited. In the current embodiment, the waterway control key 213 is provided on the pawl member 212, so that the pawl member 212 is pushed to rotate by pressing the pawl member 212. Fig.16 As shown, in other embodiments, the waterway control key 213 can be a push key, and the waterway control key 213 is connected to the pawl member 212 through a connecting rod, and the connecting rod is transferred to the waterway body 1, so that the pawl member 212 is driven to rotate by horizontally pushing the waterway control key 213. Exemplarily, the second elastic member 214 is a spring.

[0066] like Fig.12As shown, in some embodiments, in order to ensure the stability of the limit, the pawl 2121 can also be accurately reset during the reset process. The pawl 2121 and the waterway body 1 are both provided with a magnetic member 215. When the magnetic member 215 on the pawl 2121 is opposite to the magnetic member 215 on the waterway body 1, the pawl 2121 is limited and abuts against the ratchet 211, thereby ensuring the accurate reset position. In the current embodiment, the magnetic member 215 is a magnet.

[0067] In addition, if Fig.11 As shown, in order to avoid unnecessary misalignment of the pawl 2121 when the ratchet 211 rotates, resulting in misalignment and interference between the two pawls 2121 and the first ratchet tooth 2111 and the second ratchet tooth 2112, in some embodiments, a partition wall 2113 is provided on the ratchet 211, and the partition wall 2113 is arranged along the outer circumference of the ratchet 211, and the first ratchet tooth 2111 and the second ratchet tooth 2112 are located on both sides of the partition wall 2113, thereby avoiding misalignment and interference between the pawl 2121 and ensuring the stability of the limit.

[0068] like Figure 3 , Figure 4 and Figure 8 As shown, in some embodiments, when the ratchet 211 drives the water diversion member 22 to rotate, in order to avoid water leakage of the water diversion member 22 during the rotation process, a water diversion sealing ring 23 is arranged on the outer periphery of the inlet of the second water channel 12, and the water diversion member 22 presses against the water diversion sealing ring 23, thereby avoiding water leakage. Further, in order to ensure the stability of the water diversion sealing ring 23, a boss 14 is arranged in the water diversion chamber 13, and the water diversion sealing ring 23 is sleeved on the boss 14, and the inlet of the second water channel 12 is arranged at the top of the boss 14. Furthermore, a first elastic member 24 is also arranged in the water diversion chamber 13, and the first elastic member 24 is located on the side of the water diversion member 22 away from the water diversion sealing ring 23, one end of the first elastic member 24 is arranged on the water diversion member 22, and the other end is connected to the first rotating shaft 216, so that the water diversion member 22 is kept pressed against the water diversion sealing ring 23 by the first elastic member 24. Specifically, the first elastic member 24 is a spring, a first groove is provided on the water dividing member 22, a plug-in column is provided at the bottom of the first groove, one end of the first elastic member 24 is sleeved on the plug-in column, a second groove is provided at the end of the first rotating shaft 216, the first rotating shaft 216 is inserted into the first groove, and the other end of the first elastic member 24 is fixed in the second groove, and the outer wall of the first rotating shaft 216 and the inner wall of the first groove both have multiple planes to form a limit to avoid idling.

[0069] like Figure 3 , Figures 5 to 7As shown, in some embodiments, the front body 31 is provided with a switching cavity 311, wherein the water inlet 312, the first front outlet 313 and the second front outlet 314 are all connected to the switching cavity 311; wherein the switching cavity 311 has a switching port 3111, and in the extension direction of the switching cavity 311 (the direction from the switching port 3111 of the switching cavity 311 to the cavity bottom), the first front outlet 313 is closer to the switching port 3111 than the second front outlet 314, that is, in the switching cavity 31 1, the first front outlet 313 is located above the second front outlet 314, so that the water inlet 312 forms a flow channel through which water can pass through the switching chamber 311 to the first front outlet 313, and guides the water to the water diversion port 221 in the water diversion chamber 13 (the switching component 32 is in the first state); the water inlet 312 forms another flow channel through which water can pass through the switching chamber 311 to the second front outlet 314, and guides the water to the first water channel 11 (the switching component 32 is in the second state).

[0070] like Figure 6 As shown, the switching assembly 32 includes a switching shaft 321 and a third elastic member 322. The switching shaft 321 is sealed to the switching chamber 311 through the switching sealing ring through the switching port 3111, and can move in the switching chamber 311 along the extension direction of the switching chamber 311. The third elastic member 322 is arranged in the switching chamber 311, and one end is connected to the bottom of the switching chamber 311, and the other end is connected to the switching shaft 321. The switching shaft 321 is provided with a circumferentially surrounding blocking member 323. For example, the blocking member 323 is a blocking ring. The switching shaft 321 drives the blocking member 323 to move during the movement, so that the blocking tube can block the first front outlet 313 or the second front outlet 314.

[0071] In the current embodiment, the water-dividing chamber 13 has two inclined walls 3112 surrounding the switching chamber 311 along the extension direction of the switching chamber 311, the two inclined walls 3112 are arranged opposite to each other, and the two inclined walls 3112 are located between the first front outlet 313 and the second front outlet 314, the thickness of the blocking member 323 is less than the distance between the two inclined walls 3112, and the blocking member 323 moves between the two inclined walls 3112 through the switching shaft 321; when the blocking member 323 abuts against the inclined wall 3112 located on the side close to the switching port 3111, the water flow can flow to the second front outlet 314 through the gap between the blocking member 323 and the inclined wall 3112 on the side close to the bottom of the water-dividing chamber 13, thereby diverting the water. Guided to the first water channel 11 (the switching component 32 is in the second state); similarly, when the blocking member 323 abuts against the inclined wall 3112 located on the side of the bottom of the water diversion chamber 13, the water flow can flow to the first front outlet 313 through the gap between the blocking member 323 and the inclined wall 3112 on the side of the switching port 3111 close to the water diversion chamber 13, and guide the water to the water diversion port 221 in the water diversion chamber 13 (the switching component 32 is in the first state); because the switching shaft 321 is connected to the third elastic member 322, the third elastic member 322 can keep the blocking member 323 against the inclined wall 3112 on the side of the switching port 3111 close to the water diversion chamber 13, thereby maintaining the state of blocking the first front outlet 313.

[0072] When the switching shaft 321 squeezes the third elastic member 322, the blocking member 323 abuts against the inclined wall 3112 on the side of the bottom of the water diversion chamber 13. At this time, the restoring force generated by the third elastic member 322 is less than the pressure of the water pressure, and the water flow is converted from flowing toward the second front outlet 314 to flowing toward the first front outlet 313. At this time, even if there is no artificial external force to continuously press the switching shaft 321, the water pressure can always act on the blocking member 323 to press the third elastic member 322, so that it remains in the first state of flowing through the first front outlet 313; similarly, when the water pressure is lost after the water is turned off, even if there is no external force, the third elastic member 322 can make it return to the second state in which the water diversion chamber 13 is connected to the second front outlet 314, that is, when the water is turned on again, the water flow will enter the first water channel 11 through the second front outlet 314, forming a default initial water outlet state.

[0073] like Figure 3 , Figures 14 to 16As shown, in some embodiments, in order to facilitate control and avoid more complicated control logic, the cyclic switching shower 100 also includes a linkage mechanism 4, which connects the switching component 32 and the control component 21. When the switching component 32 is in the second state, the control component 21 drives the water diversion component 22 to rotate to switch the water outlet mode. At this time, the linkage mechanism 4 can drive the switching component 32 to switch from the second state to the first state, so that water can flow into the water diversion port 221. The water pressure keeps the switching component 32 in the first state. The control component 21 is driven again to switch the water diversion component 22 again to switch the water outlet mode. Therefore, the front switching mechanism 3 can be controlled by controlling the control component 21 of the water channel switching mechanism 2 and the linkage mechanism 4 to achieve simultaneous switching of the water channel and the water outlet mode, which is convenient for operation.

[0074] Based on the above logic, in the current embodiment, the linkage mechanism 4 includes a linkage body 41, the first end of the linkage body 41 is connected to the pawl 2121, and a second rotating shaft 42 is arranged between the first end and the second end of the linkage body 41. The linkage body 41 is connected to the front body 31 or the waterway body 1 through the second rotating shaft 42. The second end of the linkage body 41 is located above the switching port 3111, and a low point position and a high point position are arranged on the side facing the switching port 3111. In the second state, the switching shaft 321 is against the low point position, and the linkage body 41 switches the switching shaft 321 to the low point position or the high point position during the rotation process, thereby being able to change the length of the switching shaft 321 extending out of the switching port 3111 or retracting into the switching port 3111, thereby changing the position of the switching shaft 321. In the current embodiment, a side of the linkage body 41 facing the switch port 3111 is provided with a butting groove 411, the bottom of the butting groove 411 defines the above-mentioned low point, and the outer side of the butting groove 411 defines the high point. When the switching shaft 321 butts against the bottom of the butting groove 411, the waterway control key 213 drives the pawl 212 to rotate in both directions, and the pawl 212 drives the linkage body 41 to rotate, thereby causing the second end of the linkage body 41 to rotate in both directions above the switch port 3111, so that the switch shaft 321 can enter and exit the butting groove 411 during the rotation process, changing the height of the switch shaft 321 extending out of the switch port 3111. Fig.12 and Fig.13 As shown, exemplarily, a swing groove 2122 is provided on the pawl member 212, and a swing shaft 412 is provided at the first end of the linkage body 41, and the swing shaft 412 is inserted into the swing groove 2122, so that the swing shaft 412 is pressed against the groove wall of the swing groove 2122, thereby realizing the rotation of the linkage body 41.

[0075] When in the second state, the switching shaft 321 abuts against the bottom of the abutting groove 411. At this time, the switching shaft 321 does not squeeze the third elastic member 322, the blocking member 323 blocks the first front outlet 313, and water flows out through the second front outlet 314; when the switching shaft 321 cuts out the abutting groove 411, the linkage body 41 abuts against the switching shaft 321 to squeeze the third elastic member 322, the blocking member 323 blocks the second front outlet 314, and water flows out through the first front outlet 313; although at this time, the water channel control key 213 is released to synchronize the reset of the pawl 2121 and the linkage body 41, the switching shaft 321 will not abut against the bottom of the abutting groove 411 due to the water pressure; until the water pressure disappears, the switching shaft 321 resets to abut the bottom of the abutting groove 411. Thus, the front switching mechanism 3 and the water switching mechanism 2 can be synchronously controlled by a water circuit control key 213, reducing the control structure, simplifying the control logic, facilitating operation, and the linkage mechanism is hidden in the housing 6. From the appearance, only one water circuit control key 213 is needed, and the appearance is simple and elegant. Furthermore, in order to facilitate the switching shaft 321 to enter and exit the top groove 411, the size of the top groove 411 gradually increases from the bottom of the groove to the groove mouth, that is, the groove wall of the top groove 411 is an inclined groove wall.

[0076] like Figure 3 As shown, in some embodiments, the linkage mechanism 4 may further include a limit plate 43, which is used to limit the axial movement of the linkage body 41. The form of the limit plate 43 is not specifically limited. In the current embodiment, the limit plate 43 is a cover plate, which is arranged above the linkage body 41. A space groove for the limit plate 43 to rotate can be provided on the cover plate.

[0077] In other embodiments, the switching component 32 may also include a front control key (not shown in the figure), which is used to control the switching component 32 to switch from the second state to the first state; that is, when the control switching component 32 in the cyclic switching shower is in the second state, it is manually switched to the first state through the front control key, so that the water flows into the water outlet 221, and then the water outlet mode is switched through the water channel control key 213.

[0078] In some embodiments, the circulating switching shower head 100 is also provided with a water inlet connector 5, which is connected to the water inlet 312. The water inlet connector 5 is provided with an incremental component 51 capable of increasing the water inlet flow rate. The incremental component 51 for increasing the water inlet flow rate is a prior art (see the description in the CN103527815B patent), and will not be described in detail.

[0079] like Fig.17 As shown, the present application also provides a faucet, which includes the above-mentioned circulation switching shower head 100.

[0080] The present application also provides a shower system, which includes the above-mentioned cyclic switching shower head 100. Thus, on the one hand, a fixed water outlet mode can be ensured at the beginning of use, and the water outlet mode can be switched in a two-way cycle during use, thereby simplifying the water outlet control cycle and improving the user experience.

[0081] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
