[0046] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0047] With reference to the description, a single key switching mechanism comprises a water channel body 2 and a switching assembly 3, which is installed on the water channel body 2.

[0048] With reference to the drawings Figure 1 to the drawings Figure 3The switching assembly 3 comprises a key cap, a driving key 32, a swing member 33 and an auxiliary elastic member 34. The driving key 32 is installed in the positioning groove 24 of the water channel body. The driving key 32 is connected with the key cap. The driving key 32 is considered as the initial position when it is not driven to move the swing member 33 and is stationary relative to the water channel body 2. The driving key 32 is considered as the driving position when it drives the swing member 33 to move until it is stationary relative to the water channel body 2. The driving key can be switched between the driving position and the initial position under the action or removal of external force. In addition, the bottom end of the driving key 32 is provided with a first driving surface 32a and a second driving surface 32b. The first driving surface 32a and the second driving surface 32b are arranged in a staggered manner. In a preferred embodiment, referring to the accompanying drawings, the first driving surface 32a or the second driving surface 32b is an inclined surface. The first driving surface 32a and the second driving surface 32b are distributed on opposite sides of the bottom end of the driving key. The first driving surface 32a and the second driving surface 32b are inclined relative to the central axis direction of the driving key. That is, the inclined surfaces of the first driving surface 32a and the second driving surface 32b are arranged in opposite directions. Further, the driving key 32 and the water channel body 2 are provided with spring members 34a. For example, referring to the accompanying drawings, the driving key 32 further comprises left and right branch arms 32c and 32d. The left and right branch arms can interact with the two spring members 34a respectively to provide power for the driving key to return to the initial position. Figures 4A-4B and the accompanying drawings Figure 5 The first driving surface 32a or the second driving surface 32b is an inclined surface. The first driving surface 32a and the second driving surface 32b are distributed on opposite sides of the bottom end of the driving key. The first driving surface 32a and the second driving surface 32b are inclined relative to the central axis direction of the driving key. That is, the inclined surfaces of the first driving surface 32a and the second driving surface 32b are arranged in opposite directions. Further, the driving key 32 and the water channel body 2 are provided with spring members 34a. For example, referring to the accompanying drawings, the driving key 32 further comprises left and right branch arms 32c and 32d. The left and right branch arms can interact with the two spring members 34a respectively to provide power for the driving key to return to the initial position.

[0049] Referring to the accompanying drawings Figure 6 to the accompanying drawings Figure 9 It is the first embodiment of the auxiliary elastic member structure. The upper end of the swing member 33 has a first driven surface 33a and a second driven surface 33b. The first driven surface 33a cooperates with the first driving surface 32a to drive. The second driven surface 33b cooperates with the second driving surface 32b to drive. That is, the swing member 33 and the driving key 32 form two sets of corresponding driving relationships. During the driving of the swing member 33 by the driving key 32, only one driving surface can drive the corresponding driven surface. At this time, it is considered as the effective driving relationship. The lower end of the swing member 33 is provided with a pivot hole e. The swing member 33 is movably connected with the movable rod 42a. The swing member 33 is limited to not move axially relative to the movable rod 42a, but can rotate relative to the movable rod 42a. The driving key 32 drives the swing member 33 to move, thereby driving the movable rod to move synchronously.

[0050] The front end face and the rear end face of the swing member 33 are further provided with a first protrusion 33c and a second protrusion 33d, respectively, which are arranged staggeredly. The protrusions are used to enable one of the protrusions to press the elastic arm 34b to cause elastic deformation of the elastic arm during the movement of the swing member, and the elastic arm 34b is always in contact with the deformed elastic arm during the process of returning to the original state after the external driving force disappears, so as to enable the swing member to rotate relative to the axis of the movable rod. The auxiliary elastic member 34 is installed on the water channel body 2, and the auxiliary elastic member 34 comprises two elastic arms 34b arranged oppositely and staggeredly. The elastic arm 34b is a protruding and suspended elastic arm, and has elasticity. During the movement of the swing member 33 driven by the driving key 32, one of the elastic arms 34b is deformed elastically. After the external driving force disappears, the elastic arm 34b returns to the original state under the action of the elastic force, so as to cause the swing member 33 to rotate relative to the axis of the movable rod, thereby realizing the change of the effective driving relationship, i.e., the auxiliary elastic member 34 can push the swing member 33 to rotate, so that the two groups of driving relationships are changed.

[0051] Referring to the accompanying drawings Figure 6 , the accompanying drawings Figure 10 , and the accompanying drawings Figure 11 , which is a second embodiment of the auxiliary elastic member structure, and the same parts as the first embodiment will not be repeated. The auxiliary elastic member 34' is two in number and is fixedly installed on the water channel body 2. The auxiliary elastic member 34' is arranged staggeredly on the water channel body 2 and is arranged in cooperation with the positions of the protrusions. The auxiliary elastic member 34' is composed of the spring member 34a and the elastic arm 34b'. One end of the spring member 34a cooperates with the left supporting arm 32c or the right supporting arm 32d to provide a certain driving force for the driving key to return to the original position. The elastic arm 34b' is a protruding and suspended elastic arm and has elasticity. The elastic arm 34b' can be deformed elastically under the action of an external force and returns to the original state after the external force disappears. During the movement of the swing member 33 driven by the driving key 32, one of the elastic arms 34b' is deformed elastically in cooperation with the first protrusion 33c or the second protrusion 33d, and the deformed elastic arm 34b' is always in contact with the first or second protrusion during the process of returning to the original state after the external driving force disappears, so as to enable the swing member to rotate relative to the axis of the movable rod. The auxiliary elastic member 34' can push the swing member 33 to rotate, so that the two groups of driving relationships are changed.

[0052] Referring to the accompanying drawings Figure 12 , and the accompanying drawings Figures 13A-13Bwhich is the third embodiment of the auxiliary elastic member structure, and the same parts as the first embodiment will not be repeated. The auxiliary elastic member 34" includes two elastic arms 34b" which are arranged at the front and rear ends of the swing member 33. When the swing member 33 is driven by the driving key 32, one of the elastic arms 34b" on the swing member can be elastically deformed by the limiting plate or the water channel body, and then restored to its original shape under the elastic force after the external force on the driving key 32 disappears, so that the swing member 33 can rotate relative to the shaft of the movable rod, thereby realizing the conversion of the effective driving relationship, i.e. the auxiliary elastic member 34" can push the swing member 33 to rotate to convert the two groups of driving relationships.

[0053] The movement process of the single-key switching mechanism will be described with reference to the accompanying drawings. Referring to Fig. 1, Figure 14A In the initial state, the driving key 32 is in the initial position under the action of the spring member 34a; referring to Fig. 2, Figure 14B After the external force presses the driving key 32 for the first time, the first driving surface 32a of the driving key 32 drives the first driven surface 33a of the swing member, and the swing member 33 moves forward and drives the movable rod connected thereto to move forward until the driving key 32 moves to the driving position, and at the same time, the first protrusion 33c can compress the elastic arm 34b during the movement of the swing member to cause the elastic arm to deform; referring to Fig. 3, Figure 14C After the external force is removed, the driving key 32 returns to the initial position under the action of the spring member 34a, and the swing member 33 rotates around the shaft of the movable rod 42a under the elastic force of the elastic arm 34b until it abuts against the limiting plate 26 on the water channel body, at which moment the effective driving relationship is converted from the cooperation between the first driving surface 32a and the first driven surface 33a to the cooperation between the second driving surface 32b and the second driven surface 33b; referring to Fig. 4, Figure 14D After the external force continues to press the driving key 32 for the second time, the second driving surface 32b of the driving key 32 drives the second driven surface 33b, and the movable rod moves backward until the driving key 32 is in the driving position, at which moment the second protrusion 33d compresses the other elastic arm 34b to cause the elastic arm to deform; referring to Fig. 5, Figure 14E After the external force is removed, the driving key 32 returns to the initial position under the action of the spring member 34a, and the swing member 33 rotates around the shaft of the movable rod 42a under the action of the elastic arm 34b until it abuts against the limiting plate 26 on the water channel body, at which moment the effective driving relationship is converted from the cooperation between the second driving surface 32b and the second driven surface 33b to the cooperation between the first driving surface 32a and the first driven surface 33a, so that the two different driving relationships can be converted to each other to realize the single-key cyclic switching requirement.

[0054] The single-key switching mechanism can be applied to a water outlet device. The water outlet device comprises the single-key switching mechanism and a water distribution assembly 4. The single-key switching mechanism comprises the water channel body 2 and the switching assembly 3. The water channel body 2 is connected to an inlet connector 7 to access a water channel.

[0055] In a preferred embodiment, reference is made to the attached drawings Figure 15 to the attached Figure 18 The water channel body 2 is provided with a first water outlet 21 and a second water outlet 22. The water channel body 2 is provided with a water passing channel 20 and a water distribution cavity 23. The first water outlet 21 and the second water outlet 22 are arranged at positions corresponding to the water distribution cavity 23. The water distribution cavity 23 and the water passing channel 20 are provided with a water inlet b. The water channels of the water distribution cavity 23 and the water passing channel 20 are communicated through the water inlet b. One end of the water distribution cavity 23 is connected to a water distribution end cover 41. The other end of the water distribution cavity 23 is connected to a water distribution valve rod 42. The water channel body 2 is further provided with a positioning groove 24 and a limiting plate 26. The driving key 32 is installed in the positioning groove 24 to limit the linear movement of the driving key 32 relative to the water channel body 2, thereby ensuring the reliability of the driving key 32. The limiting plate 26 is used to limit the rotation angle range of the swing member 33 relative to the activity rod axis, thereby limiting the swing angle of the swing member 33 within a certain range. The limiting plate 26 can be directly connected to the positioning groove 24 to form an integral body.

[0056] Referring to the drawings, the water diversion assembly 4 comprises a water diversion end cover 41 and a water diversion valve rod 42. The water diversion end cover 41 is connected with the water channel body 2, and a first sealing ring a1 is arranged between the water diversion end cover 41 and the water channel body 2. The water diversion end cover 41 cooperates with the water channel body 2 to form the water diversion cavity 23. The water diversion end cover 41 has a water passing hole 4a and a connecting rod 4b. The water passing hole 4a is in communication with the first water outlet 21. The connecting rod 4b is connected with the water diversion valve rod 42. In addition, the water diversion end cover 41 has a first sealing surface p1 located in the water diversion cavity 23. The water diversion cavity 23 also has a second sealing surface p2 located on the water channel body 2 and between the first sealing surface p1 and the second water outlet 22. The water diversion valve rod 42 comprises a movable rod 42a and a water diversion sealing member 42b. The movable rod 42a is connected with the swing member through a pivot hole e. The movable rod 42a has a positioning piece 42c. When the movable rod 42a is connected with the pivot hole e, the positioning piece 42c can position the swing member 33 at a certain position, prevent the swing member from moving axially relative to the movable rod 42a, and facilitate the swing member 33 to swing relative to the movable rod 42a, thereby ensuring the reliability of the product. One end of the movable rod 42a has a piston. The water diversion sealing member 42b is formed by sleeving a sealing member q2 on the piston. The effective pressure bearing areas s1 and s2 of the water diversion sealing member 42 on both sides in the water flow are different, thereby forming a pressure difference, so that the water diversion valve rod can be kept at a certain position. The middle part of the piston is provided with a through hole q3. The connecting rod 4b is connected with the water diversion valve rod 42 through the through hole q3. The water diversion valve rod 42 can move axially along the connecting rod 4b, so that the water passing channel 20 is in communication with one of the first water outlet 21 and the second water outlet 22.

[0057] Preferably, the water diversion valve rod 42 and the water channel body 2 have a sealing member f therebetween, so as to ensure the sealing of the two and prevent water leakage.

[0058] In an optional embodiment, a reset spring can be arranged between the end surface of the water diversion valve rod 42 and the water diversion end cover 41. The reset spring can keep the water diversion valve rod at a default position under low water pressure or no water pressure, so that the water diversion sealing member can be in contact with the second sealing surface to block the communication between the second water outlet and the water passing channel.

[0059] The working mode of the single-key switching pull head will be described below with reference to the drawings. Figures 19A-19E Figure 19A ​, the water distribution valve rod 42 is in the second position, at this time, the first water outlet 21 is in communication with the water channel 20, and the water flow from the first water outlet 21 flows out through the water outlet 4a of the water distribution end cover to be used by the user, for example, the water outlet mode is soft water outlet. Referring to the accompanying drawings Figure 19B When the first pressing force is applied to the driving key 32, the first driving surface 32a at the bottom end of the driving key drives the first driven surface 33a of the swing piece, and then the swing piece 33 drives the water distribution valve rod 42 to move forward until the water distribution sealing piece 42b of the water distribution valve rod 42 contacts the first sealing surface p1, and the water distribution valve rod 42 moves from the second position to the first position, at this time, the communication between the water channel 20 and the first water outlet 21 is blocked, and the second water outlet 22 is in communication with the water channel 20. Due to the difference between the effective pressure areas s1 and s2 of the water distribution valve rod 42, a water pressure difference is generated, and the water pressure can keep the water distribution valve rod 42 in the first position, and the first protrusion 33c of the swing piece can compress the elastic arm 34b of one of the auxiliary elastic pieces to cause a certain deformation. Referring to the accompanying drawings Figure 19C When the pressing force is removed, the driving key 32 returns to the initial position under the action of the spring piece 34a, and the swing piece 33 rotates under the action of the compressed elastic arm 34b until the swing piece 33 is limited by the limiting plate 26 of the water channel body, at this time, the water distribution valve rod 42 is still in the first position under the action of the water pressure difference, and the effective driving relationship is converted from the cooperation between the first driving surface 32a and the first driven surface 33a to the cooperation between the second driving surface 32b and the second driven surface 33b. Referring to the accompanying drawings Figure 19D When the user presses the driving key 32 for the second time, the second driving surface 32b at the bottom end of the driving key drives the second driven surface 33b, and the water distribution valve rod 42 moves backward until the water distribution sealing piece 42b contacts the second sealing surface p2, at this time, the first water outlet 21 is in communication with the water channel 20, and the water distribution valve rod 42 is in the second position. Due to the pressure difference on both sides of the water distribution valve rod 42 or the action of the return spring, the water distribution valve rod 42 can be kept in the second position, and at this time, the second protrusion 33d can compress the elastic arm 34b of the other auxiliary elastic piece to cause a deformation; Referring to the accompanying drawings Figure 19EWhen the external force is removed, the driving key 32 returns to the initial position under the action of the spring member 34a, and the swing member 33 rotates under the action of the compressed elastic arm 34b until abutting against the limiting plate 26, at this time the water distribution valve rod 42 is still at the second position, and the effective driving relationship at this moment is converted from the cooperation relationship between the second driving surface 32b and the second driven surface 33b to the cooperation relationship between the first driving surface 32a and the first driven surface 33a. Through the above working mode, it can be known that the single-key pull head of the present application can realize the requirement of switching different water paths by using a single key through mutual conversion between different groups of effective driving relationships, and can also meet the requirement of automatically switching the water path to the default commonly used water path after the pull head stops water output. In this way, the single-key switching pull head of the present application can realize single-key switching and automatic switching to the default water type, and the user only needs to press once to realize one-time switching, and has the function of default water type, which can let the user use the high-frequency water type without frequent switching, is convenient to use, and has better experience.
