[0016] Scheme thirteen: a mounting method of a swing structure, which is used to mount the swing structure according to any one of schemes one to thirteen; comprising the following mounting steps: hingedly connecting the swing member and the bracket to form the insertion assembly; placing the insertion assembly into the accommodation cavity of the body from the first opening; sleeving the shell on the body and making the water outlet on the shell face the first opening.

[0017] Scheme fourteen: a water outlet device, comprising the swing structure according to any one of schemes one to twelve, and the water outlet is obliquely arranged.

[0018] From the above description of the present application, the present application has the following beneficial effects relative to the prior art:

[0019] 1. The insertion assembly comprises the bracket and the swing member, so that the swing member is hingedly connected with the bracket and then inserted into the accommodation cavity together with the bracket, the bracket is adapted to the cavity wall of the accommodation cavity, so that the bracket is more firmly installed. When the swing structure is used in a small space, the size thereof is small, in order to facilitate installation, a pin shaft is generally arranged to realize the rotary connection between the body and the swing member, and therefore a hole needs to be arranged on the body. The hole on the body needs to be sealed to avoid water leakage of the body, and it is difficult to seal the small hole. The present scheme installs the swing member on the bracket without arranging another hole on the body for installing the swing member, which is convenient to install and does not need to consider the strength and sealing performance of the body after the hole is arranged, and only needs to consider the limiting of the bracket during installation, which has a lower precision requirement compared with the case without the bracket. The shell is sleeved on the body to limit the bracket, so as to avoid the bracket from being separated from the accommodation cavity. When the swing member is only subjected to gravity, the groove faces the water outlet, when the water outlet is supplied with water, the water flow acts on the groove, so that the swing member swings in one direction, and in the process of swinging, the swing member gradually swings to the other side under the influence of the water pressure in the accommodation cavity, and the process is repeatedly performed, so that the water outlet flows with swinging water.

[0020] 2. An expansion section adjacent to the water outlet is set up. The cavity wall of the receiving cavity gradually moves away from the water inlet direction within the expansion section, so that when water enters the water outlet from the inlet channel, a wall adhesion effect is formed at the expansion section, making it easier for the water flow to drive the swinging component to swing. The swinging component is in its initial state under its own weight. The inclined water flow into the groove generates a torque on the end of the swinging component where the groove is located. Since the direction of water inclination is random, the direction of the torque is also random, causing the swinging component to swing randomly to one side. When the swinging component swings to its maximum angle, the area connecting the water outlet and the water outlet becomes smaller, causing the water flow to accumulate between the swinging component and the water outlet. The water flow between the swinging component and the water outlet is depressurized through the water outlet, causing an imbalance in water pressure on the swinging component. The change in the torque exerted by the water flow on the swinging component causes the swinging component to gradually return to its initial state. When the swinging component returns to its initial state, under the action of inertia, the water flow entering the groove again drives the end of the swinging component where the groove is located to swing to the other side. Under the action of water flow, the oscillating component repeats the above process to achieve reciprocating oscillation, so that the water flowing out of the outlet is oscillating water.

[0021] 3. A recessed portion facing the first plane is provided on the first wall and the second wall. When the swinging member is subjected to the action of water flow during the swinging process, the water flow accumulates in the recessed portion on the first wall or the second wall, which is more conducive to the swinging member returning to its original position smoothly and realizing reciprocating swinging, so as to continuously generate swinging water.

[0022] 4. The first wall and the second wall are formed by setting a first section and a second section. The two first sections gradually approach each other along their extension direction and form a recess at the connection between the first section and the second section. The structure is simple, and each first section guides the water, which helps the water to accumulate in the recess.

[0023] 5. By providing a first extension and a second extension on the two side walls of the swing member perpendicular to its hinge axis, a first water storage chamber and a second water storage chamber are formed. When the swing member swings to one side and water accumulates in the recess, each of the first extensions and each of the second extensions can block the water flow from the gap between the two side walls of the swing member perpendicular to the hinge axis and the inner wall of the bracket or the cavity wall to the outlet, which is more conducive to the smooth reset of the swing member.

[0024] 6. The size of the water inlet is smaller than the opening size of the groove, which helps to ensure that most of the water in the water inlet flows into the groove when the swinging part is in the initial state, making it easier to drive the swinging part to swing.

[0025] 7. The oscillating component forms a fulcrum at its hinge axis. The two ends of the oscillating component are subjected to water flow, which generates torque. The magnitude of the torque is related to the lever arm. Because the lever arm from one end of the oscillating component with a groove to the hinge axis is smaller than the lever arm generated at the other end by the water flow to the hinge axis, when the oscillating component rotates to one side to its maximum angle, the water flow acts on the oscillating component to more easily cause it to return to its original position.

[0026] 8、When the swing member rotates to the maximum angle position, the opening of the groove is located on one side of the first plane, at this time the water flow flowing into the containing cavity mainly impacts the first wall or the second wall of the swing member, thereby reducing the swing frequency of the swing member, and it can also ensure that the swing member can swing to the maximum angle position, avoiding the swing member not being able to swing to the position.

[0027] 9、The swing member is provided with mounting protrusions on the two side walls perpendicular to the hinge axis, the swing member is placed into the first cavity of the support, and is matched with the mounting slot of the support, so that the swing member is hinged with the support, and installation is convenient. Since the mounting protrusions are matched with the mounting slot, the body does not have a hole, and there is no sealing problem, and the swing member and the support do not have a hole, and the overall strength is not affected.

[0028] 10、When the swing member swings to the maximum angle position, one end provided with the groove abuts against or is close to the cavity wall of the containing cavity, and / or the other end abuts against or is close to the cavity wall of the first cavity, so that the communication area of the water inlet and the water outlet is reduced when the swing member swings to the maximum angle position, which is beneficial to the accumulation of water flow between the swing member and the water inlet, and helps the swing member to reset.

[0029] 11、The side wall of the swing member provided with the mounting protrusions and the side wall of the first cavity provided with the mounting slot have a gap, so that the water flow between the side wall of the swing member provided with the mounting protrusions and the side wall of the first cavity provided with the mounting slot is small, and it is ensured that the swing member can rotate smoothly.

[0030] 12、The first limiting surface is arranged in the containing cavity and matched with the shell, so that the support is limited in the insertion direction, avoiding the support being displaced after the water flow enters the containing cavity, and affecting the swing effect of the swing member.

[0031] 13、When the swing structure is installed, the swing member is first hinged with the support, then the insertion assembly is placed into the containing cavity of the body from the first opening, and then the shell is sleeved on the body. For a swing structure with small size, the containing cavity is small, if the swing member is rotationally connected with the body, it is not easy to operate, and in order to facilitate installation, a hole needs to be opened in the body or the swing member, and the swing member is installed by a pin shaft, which has a sealing problem; the swing member is installed on the support and directly inserted into the containing cavity in this scheme, which is more convenient, and the body does not have a sealing problem and will not cause water to leak out of the body. If the swing member is installed by a pin shaft, when it is necessary to change the position of the hinge axis of the swing member, the body and the swing member need to be re-produced, which increases the production cost; the support and the swing member can be adjusted in this scheme, which reduces the production cost. On the other hand, in order to meet the needs of different customers and realize different swing water effect, when producing, the body does not need to be improved, and only the swing member needs to be improved, as long as the improved swing member can be placed into the support and the support can be placed into the body, therefore the body has universality and low cost.

[0032] 14. The water outlet device comprises the swing structure as described above, and has all the beneficial effects of the swing structure. The water outlet is obliquely arranged, and can guide the swing water flowing out of the water outlet to align with the user. BRIEF DESCRIPTION OF DRAWINGS

[0059] As shown in Figures 1 to 9 , the water outlet device 100 comprises a swinging structure, which comprises a body 1, an insertion assembly 2, a shell 3, a first sealing ring 4, a second sealing ring 5, and a third sealing ring 6.

[0060] As shown in Figures 1 to 9 , the body 1 is provided with a receiving cavity 11 and a water inlet channel 14. The receiving cavity 11 is provided with a first opening 12 at one end and a water passing opening 13 at the other end, which communicates the receiving cavity 11 and the water inlet channel 14. The cavity wall of the receiving cavity 11 is provided with an expansion section 111 adjacent to the water passing opening 13 in the direction from the water passing opening 13 to the first opening 12. The insertion assembly 2 is detachably placed into the receiving cavity 11 from the first opening 12, which comprises a bracket 22 and a swinging member 21; the bracket 22 is adapted to the receiving cavity 11, and the swinging member 21 is hingedly connected to the bracket 22; one end of the swinging member 21 is provided with a groove 2119, and when the swinging member 21 is only subjected to gravity, the opening of the groove 2119 faces the water passing opening 13 and is at least partially located in the expansion section 111. Water flows from the water inlet channel 14 and is sprayed from the water passing opening 13 to the groove 2119, so that the swinging member 21 swings in the receiving cavity 11. The shell 3 is sleeved on the body 1 and is adapted to abut against the bracket 22 to prevent the bracket 22 from being detached from the receiving cavity 11, and the portion of the shell 3 closing the first opening 12 is provided with a water outlet opening 31 communicating with the receiving cavity 11, and the water outlet opening 31 sprays water splashes when the swinging member 21 swings.

[0061] In the present embodiment, the direction of the insertion assembly 2 inserted into the receiving cavity is a first direction D1, and the hinging axis of the swinging member 21 is perpendicular to the first direction D1.

[0062] Specifically, as shown in Figures 1 to 3 and Figure 6As shown, the body 1 is a substantially cylindrical member extending along a second direction D2 perpendicular to the first direction D1, and is provided with a plurality of accommodating cavities 11 along the second direction D2, in this embodiment, two accommodating cavities 11 are provided, each of the accommodating cavities 11 is provided with a first opening 12 at one end and a water passage 13 at the other end. The body 1 is further provided with a water inlet channel 14 communicating the water passages 13 of the accommodating cavities 11, and the water inlet channel 14 is open at one end of the body 1. In this embodiment, the second direction D2 is parallel to the hinge axis of the swing member 21.

[0063] As shown in Figure 2 , Figure 6 and Figure 7 , a plane parallel to the extension direction of the water passage 13 and passing through the hinge axis of the swing member 21 is defined as a first plane A1. The side walls of the accommodating cavities 11 on both sides of the first plane A1 are respectively a third wall 15 and a fourth wall 16. The third wall 15 and the fourth wall 16 are both adjacent to the water passage 13, and the third wall 15 and the fourth wall 16 respectively include a first inclined section 151 and a second inclined section 161 gradually away from the first plane A1 along the water inlet direction of the water passage 13. The first inclined section 151 and the second inclined section 161 make the accommodating cavities 11 form the above-mentioned expansion section 111. Due to the provision of the first inclined section 151 and the second inclined section 161, the water entering the accommodating cavities 11 from the water passage 13 produces a wall attachment effect, so that the water flow is more likely to drive the swing member 21 to swing. The accommodating cavities 11 are further provided with a first limiting surface 17 facing the first opening 12. As shown in Figure 3 , the body 1 is provided with a first sealing ring groove 18a on the side wall near the open end of the water inlet channel 14, the body 1 is further provided with a second sealing ring groove 19 surrounding the two water passages 13, and the body 1 is further provided with a third sealing ring groove 18b between the two accommodating cavities 11. In this embodiment, the first sealing ring groove 18a is provided with two.

[0064] As shown in Figure 4 and Figure 5 , when the swing member 21 is only subjected to gravity, the first wall 2111 and the second wall 2112 on both sides of the first plane A1 are both provided with a recessed portion 2113 facing the first plane A1. The first wall 2111 and the second wall 2112 both include a first section 2114 and a second section 2115 arranged along the extension direction thereof, when the swing member 21 is only subjected to gravity, the first section 2114 is closer to the water passage 13 than the second section 2115. The two first sections 2114 gradually approach along the extension direction thereof, and the two second sections 2115 are parallel to each other or gradually away from each other along the extension direction thereof. The connection between each first section 2114 and each second section 2115 forms the recessed portion 2113.

[0065] As shown in Figure 4 and Figure 5As shown, in the present embodiment, the first wall 2111 and the second wall 2112 are provided with recessed portions 2113 recessed towards the first plane A1, when the swing member 21 is swung under the action of the water flow, the water flow is accumulated in the recessed portions 2113 on the first wall 2111 or the second wall 2112, which is more conducive to the smooth resetting of the swing member 21, and the reciprocating swing is realized to continuously generate the swing water. The first wall 2111 and the second wall 2112 are provided with a first section 2114 and a second section 2115, the two first sections 2114 gradually approach along the extension direction thereof, and the recessed portions 2113 are formed at the connection between the first section 2114 and the second section 2115, which is simple in structure, and the water is guided by each first section 2114 to help the water to be accumulated in the recessed portions 2113. The two second sections 2115 gradually move away from the first direction D1, and such arrangement is more conducive to the accumulation of water flow in the recessed portions 2113.

[0066] As shown in Figure 4 and Figure 5 The swing member 21 is provided with a first extension portion 2116, a second extension portion 2117 and a mounting protrusion 2118 on the two side walls perpendicular to the hinge axis thereof. The first extension portion 2116 and the second extension portion 2117 are located on the two sides of the first plane A1. Among them, the first wall 2111 is located between the two first extension portions 2116, and the first wall 2111 and the two first extension portions 2116 enclose the first water storage cavity; the second wall 2112 is located between the two second extension portions 2117, and the second wall 2112 and the two second extension portions 2117 enclose the second water storage cavity. In the present embodiment, the first extension portion 2116 and the second extension portion 2117 are arranged on the two side walls perpendicular to the hinge axis of the swing member 21 to form the first water storage cavity and the second water storage cavity, when the swing member 21 swings to one side and accumulates water in the recessed portion 2113, each first extension portion 2116 and each second extension portion 2117 can block the water flow from flowing to the water outlet 31 from the gap between the two side walls perpendicular to the hinge axis of the swing member 21 and the inner wall of the bracket 22 or the cavity wall of the accommodation cavity 11, which is more conducive to the smooth resetting of the swing member 21.

[0067] As shown in Figure 4 and Figure 5As shown, the two mounting protrusions 2118 form the hinged shaft of the swing member 21 rotating around the hinged axis, and the two mounting protrusions 2118 are both closer to the swing member 21 closer to one end of the groove 2119, so that the swing member 21 is subjected to the water flow to generate a force arm at the end of the swing member 21 provided with the groove 2119 to the hinged axis smaller than the force arm at the other end to the hinged axis. Since the position of the swing member 21 at the hinged axis forms a fulcrum, the swing member 21 is subjected to the water flow to generate a torque at both ends, and the size of the torque is related to the force arm. Since the swing member 21 is provided with the groove 2119 at one end to the hinged axis smaller than the force arm at the other end to the hinged axis, when the swing member 21 rotates to the maximum angle on one side, the water flow acting on the swing member 21 is more likely to make the swing member 21 reset.

[0068] Specifically, as shown in Figure 4 and Figure 5 The swing member 21 includes a swing member body 211 extending in the first direction D1. The swing member body 211 is provided with the above-mentioned groove 2119, and the size of the water passage 13 is smaller than the opening size of the groove 2119, which helps the water in the water passage 13 to flow into the groove 2119 when the swing member 21 is in the initial state, and more easily drives the swing member 21 to swing.

[0069] As shown in Figure 4 and Figure 5 The mounting protrusions 2118 are arranged on the two side walls of the swing member body 211 perpendicular to the hinged axis, the two side walls of the swing member body 211 on both sides of the first plane A1 form the above-mentioned first wall 2111 and the second wall 2112, and the two side walls of the swing member body 211 perpendicular to the hinged axis are provided with the above-mentioned first extension 2116 and the second extension 2117, each first extension 2116 and each second extension 2117 extend away from the first plane A1, and each first extension 2116 and each second extension 2117 make the two side walls of the swing member body 211 perpendicular to the hinged axis form a water droplet type extending away from the first direction D1.

[0070] As shown in Figure 5 The number of the brackets 22 is adapted to the number of the accommodation cavities 11. The bracket 22 is provided with a first cavity 221 communicating with the water passage 13, the water outlet 31 and the accommodation cavity 11. The first cavity 221 is adapted to accommodate the swing member 21, and the cavity wall of the first cavity 221 is provided with a mounting groove 224 adapted to the mounting protrusion 2118. The mounting protrusion 2118 cooperates with the mounting groove 224 to make the swing member 21 hinged with the bracket 22, which is convenient to install. And since the mounting protrusion 2118 cooperates with the mounting groove 224, the body 1 does not have a hole and there is no sealing problem.

[0071] In the embodiment, the first cavity 221 penetrates through both ends of the bracket 22. The cavity wall of the first cavity 221 near the end of the water passage 13 is provided with a third opening 223, and the cavity wall of the first cavity 221 near the end of the water passage 13 is provided with a second opening 222. In the embodiment, two mounting grooves 224 are arranged on the cavity wall of the first cavity 221 near the end of the water passage 13. When the swing piece 21 is inserted into the first cavity 221 and is hinged to the bracket 22 through the mounting protrusion 2118 and the mounting groove 224, one end of the swing piece 21 provided with the groove 2119 extends out of the third opening 223 of the bracket 22, and the other end is located in the first cavity 221.

[0072] As shown in Figure 4 , a gap is arranged between the side wall of the swing piece 21 provided with the mounting protrusion 2118 and the side wall of the first cavity 221 provided with the mounting groove 224, so that the water flow between the side wall of the swing piece 21 provided with the mounting protrusion 2118 and the side wall of the first cavity 221 provided with the mounting groove 224 is small, and the swing piece 21 can rotate smoothly.

[0073] As shown in Figure 8 , when the bracket 22 and the swing piece 21 are inserted into the accommodating cavity 11, and the swing piece 21 rotates to the maximum angle position under the action of the water flow, the opening of the groove 2119 is located on one side of the first plane A1, and one end of the swing piece 21 provided with the groove 2119 abuts against or is close to the cavity wall of the accommodating cavity 11, and / or the other end abuts against or is close to the cavity wall of the first cavity 221.

[0074] In the embodiment, as shown in Figure 8 , when the swing piece 21 rotates to the maximum angle position, the opening of the groove 2119 is located on one side of the first plane A1, and at this time, the water flow flowing into the accommodating cavity 11 through the water passage 13 mainly impacts the first wall 2111 or the second wall 2112 of the swing piece 21, thereby reducing the swing frequency of the swing piece 21, and also ensuring that the swing piece 21 can swing to the maximum angle position, avoiding that the swing piece 21 cannot swing to the position. When the swing piece 21 swings to the maximum angle position, one end of the swing piece 21 provided with the groove 2119 abuts against or is close to the cavity wall of the accommodating cavity 11, and / or the other end abuts against or is close to the cavity wall of the first cavity 221, so that when the swing piece 21 swings to the maximum angle position, the communication area of the water passage 13 and the water outlet 31 is reduced, which is beneficial to the accumulation of the water flow between the swing piece 21 and the water passage 13, and helps the swing piece 21 to reset.

[0075] As shown in Figure 1 and Figure 2As shown, the shell 3 is a cylindrical shell with one end open, and is sleeved on the body 1; the shell 3 cooperates with the first limiting surface 17 to limit the bracket 22 in the insertion direction, so as to avoid the displacement of the bracket 22 after the water flow enters the accommodation cavity 11, and affect the swinging effect of the swinging member 21. The number of the water outlets 31 on the shell 3 corresponds to the number of the accommodation cavities 11, and each water outlet 31 is inclinedly arranged, and the inclined direction is to guide the swinging water to flow out from the water outlet 31 towards the user.

[0076] As shown in Figure 1 and Figure 2 , the first sealing ring 4 is provided with two first sealing ring 4 grooves, respectively sleeved on the two first sealing ring 4 grooves, for sealing the side wall of the open end of the shell 3 and the body 1.

[0077] As shown in Figure 1 and Figure 2 , the second sealing ring 5 is provided with two second sealing ring grooves 19, respectively sleeved on the two second sealing ring grooves 19, and the two second sealing rings 5 abut against the inner wall of the shell 3 when the shell 3 is sleeved on the body 1. Each second sealing ring 5 is surrounded by the side wall of the shell 3 and the side wall of the first body 1 to form a water passage cavity 1001 connected with the water passage 13 and the water inlet channel 14. The water inlet channel 14 is in communication with the two water passage cavities 1001, and the two water passage cavities 1001 are in communication with the two water passage outlets 13, respectively.

[0078] As shown in Figure 1 and Figure 2 , the third sealing ring 6 is sleeved in the third sealing ring 6 groove, and the third sealing ring 6 abuts against the inner wall of the shell 3 when the shell 3 is sleeved on the body 1, so that the first openings 12 of the two accommodation cavities 11 are sealed.

[0079] As shown in Figure 1 and Figure 9 , the embodiment also provides a mounting method of the swinging structure, which is used for mounting the above-mentioned swinging structure, and includes the following mounting steps:

[0080] The swinging member 21 is hinged with the bracket 22 to form an insertion assembly 2;

[0081] The insertion assembly 2 is placed into the accommodation cavity 11 of the body 1 from the first opening 12;

[0082] The shell 3 is sleeved on the body 1, and the water outlets 31 on the shell 3 are directed towards the first opening 12.

[0083] In the above-mentioned mounting method of the embodiment, before the shell 3 is sleeved on the body 1, the first sealing ring 4 and the second sealing ring 5 are respectively sleeved on the corresponding first sealing ring 4 groove and the second sealing ring groove 19. In the embodiment, the insertion assembly 2 is provided with two, so that the insertion assembly 2 needs to be installed twice.

[0084] In the embodiment, the insertion assembly 2 is provided with the bracket 22 and the swing piece 21, so that when the insertion assembly 2 is installed, the swing piece 21 is first hingedly connected with the bracket 22, and then the bracket 22 and the swing piece 21 are inserted into the accommodating cavity 11 from the first opening 12 along the first direction D1, and then the shell 3 is sleeved on the body 1. The bracket 22 is adapted to the cavity wall of the accommodating cavity 11, so that the bracket 22 is more firmly installed. When the swing structure is used in a narrow space, the size is small, the accommodating cavity 11 is small, and if the swing piece 21 is rotationally connected with the body 1, it is not easy to operate. In order to facilitate installation, the rotational connection between the body 1 and the swing piece 21 is generally realized by a pin shaft, so that the body 1 and the swing piece 21 need to be perforated. The perforation on the body 1 affects the strength of the body 1, and the body 1 needs to be sealed to prevent water leakage. It is difficult to seal the small hole itself. The embodiment directly inserts the swing piece 21 installed on the bracket 22 into the accommodating cavity 11 to complete the installation, which is more convenient. The body 1 does not need to be perforated to install the swing piece 21, and the strength and sealing performance of the body 1 after perforation do not need to be considered. The sealing problem of the body 1 does not cause water to leak out of the body 1. And when installing, only the limiting of the bracket 22 needs to be considered, and the precision requirement is lower than that of the swing piece 21 without being provided. The shell 3 is sleeved on the body 1 to limit the bracket 22 to prevent it from being separated from the accommodating cavity 11. If a pin shaft is used for installation, when the position of the hinge axis of the swing piece 21 needs to be changed, the body 1 and the swing piece 21 need to be re-produced, which increases the production cost. The embodiment only needs to adjust the bracket 22 and the swing piece 21 to reduce the production cost. On the other hand, in order to meet the needs of different customers and achieve different swing water effect, the body 1 does not need to be improved during production, and only the swing piece 21 needs to be improved. As long as the improved swing piece 21 can be put into the bracket 22, and the bracket 22 can be put into the body 1, the body 1 has universality and low cost.

[0085] The water outlet device 100 of the embodiment is used as follows:

[0086] As shown in Figures 1 to 9 , the water outlet processes in the two accommodating cavities 11 are the same, so the water outlet process in one accommodating cavity 11 is taken as an example for description. When used, the water inlet channel 14 is communicated with a water source outside. Water enters the water passing cavity 1001 from the water inlet channel 14, and the water in the water passing cavity 1001 enters the accommodating cavity 11 from the water passing opening 13. As shown in Figure 7As shown, since the opening of the groove 2119 is directed to the water passage 13 and partially located in the expansion section when the swing member 21 is only subjected to the gravity, the water entering the accommodating cavity 11 from the water passage 13 enters the groove 2119 and drives the swing member 21 to swing, and the water flow is more easily randomly swung due to the wall attachment effect. When the swing member 21 is in the initial state, the water flow entering the groove 2119 will apply a force to one end of the swing member 21 provided with the groove 2119, thereby forming a torque. Since the swinging direction of the water flow is random, the direction of the torque is also random at this time, so that one end of the swing member 21 provided with the groove 2119 is randomly rotated to one side.

[0087] In the embodiment, as shown, the movement of the swing member 21 is described by taking the one end of the swing member 21 provided with the groove 2119 as an example. Figure 8 When the one end of the swing member 21 provided with the groove 2119 is rotated to the right, the other end is correspondingly rotated to the left. Under the continuous action of the water flow, the swing member 21 is rotated to the first position at the maximum angle position as shown. Figure 8 At this time, one end of the swing member 21 provided with the groove 2119 abuts against or is close to the inner wall of the accommodating cavity 11, and the other end abuts against or is close to the inner wall of the first cavity 221, so that the communication area between the water passage 13 and the water outlet 31 is reduced. Moreover, under the joint action of the first wall 2111 of the recessed portion 2113 and the two first extension portions 2116, the water is gathered between the first water storage cavity and the water passage 13, and the water flow between the water outlet 31 and the swing member 21 can be discharged through the water outlet 31, so that the water pressure between the first wall 2111 and the second wall 2112 of the swing member 21 is unbalanced, and at the same time, since the force arm of the swing member 21 generated by the water flow from one end to the hinge axis is smaller than the force arm of the swing member 21 generated by the water flow from the other end to the hinge axis, the torque acting on the swing member 21 changes, so that the one end of the swing member 21 provided with the groove 2119 swings to the left, and the other end swings to the right, and gradually returns to the initial state.

[0088] When the swing member 21 returns to the initial state, the one end of the swing member 21 away from the groove 2119 will continue to swing to the right under the action of inertia. At this time, the water flow entering the groove 2119 from the water passage 13 continues to act on the swing member 21, and after the same process from the initial position to the first position, the swing member 21 is rotated to the second position as shown. Figure 9

[0089] ​After that, the swing member 21 continuously repeats the above process under the action of the water flow, realizes the reciprocating swing of the swing member 21 in the accommodating cavity 11, so that the swing water flows out of the water outlet 31, until the water inlet 13 stops water, and the swing member 21 returns to the initial position. Due to the inclined arrangement of the water outlet 31, the swing water flowing out of the water outlet 31 is guided by the inclined water outlet 31 and flows out of the water outlet 31 towards the user.
