Description

Technical Field

[0001] This utility model relates to the field of sanitary ware, and in particular to a water outlet device. Background Technology

[0002] To enhance water flow, existing bathroom products incorporate various functional components, such as those that can generate bubble water, blade water, and massage water. For massage water products, traditional methods involve intermittently controlling the water flow and adjusting the water jet frequency. However, this type of product results in a limited water jet impact point and a narrow massage area, failing to meet diverse user needs. To address the aforementioned problems, Chinese patent document (publication number CN218048601U) discloses a swing-type water outlet mechanism and a shower head having the same. The mechanism includes a water-passing body and a swinging body. The water-passing body has a water-passing cavity that communicates with a first mounting port and at least one second water-passing port formed on the water-passing body. The swinging body has a water outlet channel that communicates with at least one water inlet and at least one water outlet formed on the swinging body. The swinging body is swingably mounted on the first mounting port, which has a support portion. An abutment portion is formed on the outer periphery of the swinging body and abuts against the support portion. At least part of the support portion and / or the abutment portion is constructed as a non-horizontal surface, so that the swinging body is tilted relative to the normal direction of the first mounting port. This patent enables the swinging body to rotate through the drive of water flow, thereby forming a rotating water column, without the need for an additional drive mechanism. However, in the aforementioned patent, as water continuously enters the oscillating body and the water passage cavity, the flow of water will carry impurities into the water passage cavity, and some impurities will directly remain in the water passage cavity, causing the oscillating body to get stuck during rotation, or even the oscillating body to be unable to rotate, which in turn leads to the discontinuous water output of the rotating water column. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a water outlet device to ensure the continuity of massage water output.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A water outlet device, comprising: The main body has a water outlet; The water inlet body is rotatably disposed within the water outlet; the water inlet body has a first water-passing surface, a second water-passing surface, and a first rectifier cavity; The oscillating water outlet is oscillatingly disposed in the first rectifier cavity and is columnar in shape. The oscillating water outlet can guide the water flow leaving the outlet along a spiral motion trajectory for discharge. When the first water-passing surface is used as the water inlet surface, a flushing channel is formed between the swinging water outlet and the inner wall of the first rectifier cavity, and the flushing channel provides water flow that impacts the inner wall of the first rectifier cavity.

[0005] Furthermore, the inlet body has a first water passage and a second water passage; The swinging water outlet body has a third water passage; When the second water-passing surface serves as the water inlet surface, the first water-passing channel provides water flow that laterally impacts the oscillating water outlet, and the second water-passing channel provides water flow that axially impacts the oscillating water outlet.

[0006] Furthermore, the inlet end of the oscillating water outlet is provided with at least three blades, and all the blades are arranged at equal intervals along the circumference of the oscillating water outlet. The adjacent blades have a third water inlet for water to flow into the third water passage.

[0007] Furthermore, the water inlet body has a water inlet cavity and a rectifier, and the rectifier has a guide groove that communicates with the water inlet cavity and the first rectifier cavity respectively; The water outlet of the guide channel has a guide port, and the extension direction of at least one side wall of the guide channel is set away from the axis of the first rectifier cavity.

[0008] Furthermore, the number of the guide grooves is not equal to the number of the blades.

[0009] Furthermore, the number of the guide grooves and the number of the blades are either odd or even.

[0010] Furthermore, in the axial direction of the oscillating water outlet, the projected area of ​​the blade is L-shaped, and the blade has an impact surface for being impacted by the water flow, the impact surface being distributed radially along the oscillating water outlet.

[0011] Furthermore, the inlet body is provided with a first inner wall; When the second water-passing surface is used as the water-inlet surface, in the axial direction of the swinging water-outlet body: a first gap is formed between the water-inlet end of the swinging water-outlet body and the first inner wall, the first gap is located on the second water-passing channel, and the projection area of ​​the third water-passing channel is located on the first inner wall.

[0012] Furthermore, when the first water-passing surface serves as the water inlet surface, the swinging water outlet body presses against the first inner wall.

[0013] Furthermore, when the second water-passing surface serves as the water-inlet surface, a second gap is formed between the blade and the sidewall of the rectifier in the transverse direction of the oscillating water outlet, and the second gap is located on the first water-passing channel.

[0014] Furthermore, a first limiting surface is provided inside the first rectifier cavity, and a support platform is provided outside the swinging water outlet; When the second water-passing surface is used as the water-inlet surface, in the axial direction of the swinging water-outlet body, part of the support platform abuts against the first limiting surface or there is a gap between the support platform and the first limiting surface.

[0015] Furthermore, the water inlet has a first water outlet; When the second water-passing surface is used as the water-inlet surface, there is a first distance between the upper end face of the first rectifier cavity and the water inlet end of the first water-passing port in the axial direction of the swinging water-outlet body, and the ratio of the height of the swinging water-outlet body to the first distance is 1:1 to 1:1.2.

[0016] Furthermore, along the axial direction of the oscillating water outlet, the ratio of the height of the blade to the height of the oscillating water outlet is 1:1.5 to 1:3.

[0017] Furthermore, the first rectifier cavity has a second limiting surface near the water outlet, and the second limiting surface is an arc surface; When the second water-passing surface is used as the water inlet surface, the water outlet end of the swinging water outlet body abuts against the second limiting surface; The position of the oscillating water outlet against the second limiting surface is variable.

[0018] Furthermore, a support member is embedded in the first rectifier cavity, and the second limiting surface is located within the support member.

[0019] Furthermore, when the second water-passing surface serves as the water-inlet surface, the water outlet end of the swinging water outlet body is in line contact or point contact with the second limiting surface.

[0020] Furthermore, the first rectifier cavity has a first water inlet, and a second rectifier cavity is provided inside the first water inlet; When the second water inlet surface is used as the water inlet surface, the second rectifier cavity is located downstream of the first water outlet, and when the axis of the swinging water outlet is at an angle to the axis of the first rectifier cavity, the water flow discharged by the swinging water outlet can collide with the inner wall of the second rectifier cavity.

[0021] Furthermore, the cross-sectional area of ​​the inlet end of the first water outlet is greater than 70% of the cross-sectional area of ​​the outlet of the third water passage.

[0022] Furthermore, the drainage outlet area of ​​the third water passage is 0.7 mm². 2 ~20mm 2 .

[0023] The beneficial effects of this invention are as follows: When the second water-passing surface is used as the water inlet surface, the oscillating water outlet body oscillates in a relatively stable state within the first rectifier cavity, ultimately causing the water flowing out of the oscillating water outlet body to be discharged along a spiral motion trajectory, thereby making the water flow exhibit a noticeable pulsating sensation on the rinsing surface, achieving functions such as massage and efficient rinsing. However, after the water outlet device has been using the second water-passing surface for a long time, impurities will enter and remain in the first rectifier cavity, causing the oscillating water outlet body to become stuck in rotation. Therefore, the water inlet body and the main body of the water outlet device are flipped and connected to achieve the switching of the water inlet surface. That is, when the first water-passing surface is used as the water inlet surface, the oscillating water outlet body will form a rinsing channel with the inner wall of the first rectifier cavity. After the water flows through the first water-passing surface, part of the water flows through the third water-passing channel to rinse the interior of the oscillating water outlet body, and the other part of the water flows through the rinsing channel to rinse the first rectifier cavity. The water flow also carries impurities out from the second water-passing surface, ensuring the smooth oscillation of the oscillating water outlet body, thereby ensuring that the pulsating sensation of the water flow can be maintained continuously.

[0026] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0027] Please refer to Figures 1-17A water outlet device includes: a swinging water outlet body 1, a water inlet body 2, and a main body 3; the main body 3 has a water outlet 31; the water inlet body 2 is rotatably disposed within the water outlet 31; the water inlet body 2 has a water inlet cavity 21, a first water passage surface 26, a second water passage surface 27, a first rectifier cavity 22, and a first water passage channel and a second water passage channel communicating with the first rectifier cavity 22, the first rectifier cavity 22 having a first water passage 221; the swinging water outlet body 1 has a third water passage channel 11 communicating with the water inlet cavity 21 and the first water passage 221 respectively; the swinging water outlet body 1... The water outlet 1 is oscillatingly disposed within the first rectifier cavity 22. The oscillating water outlet 1 can guide the water flow leaving the outlet 31 to be discharged along a spiral motion trajectory. When the first water-passing surface 26 serves as the water inlet surface, a flushing channel 14 is formed between the oscillating water outlet 1 and the inner wall of the first rectifier cavity 22. The flushing channel 14 provides water flow that impacts the inner wall of the first rectifier cavity 22. When the second water-passing surface 27 serves as the water inlet surface, the first water-passing channel provides water flow that laterally impacts the oscillating water outlet 1, and the second water-passing channel provides water flow that axially impacts the oscillating water outlet 1.

[0028] Specifically, the inlet end of the oscillating water outlet 1 is provided with blades 12; when the first water-passing surface 26 is used as the water-passing surface, in the axial direction of the oscillating water outlet 1: a first gap d is formed between the inlet end of the oscillating water outlet 1 and the first inner wall 20 in the water inlet cavity 21. The first gap d is located on the second water-passing channel, and the projection area of ​​the third water-passing channel 11 is located on the first inner wall 20, so that the water flow at least bypasses part of the third water-passing channel 11 to impact the oscillating water outlet 1 or the blades 12; in the transverse direction of the oscillating water outlet 1: a second gap h is formed between the blades 12 and the side wall of the rectifier 23. The second gap h is located on the first water-passing channel. The second gap h allows the water flow to pass through the rectifier 23 and the second gap h in sequence, and then impact the oscillating water outlet 1 or the blades 12 in the radial direction of the oscillating water outlet 1.

[0029] The lateral direction refers to the direction that is perpendicular to the axis of the oscillating water outlet 1 but avoids the axis of the oscillating water outlet 1. When the oscillating water outlet 1 is a cylinder or part of it is a cylinder, the lateral direction can also be understood as the direction between the radial and tangential directions of the oscillating water outlet 1, and the lateral direction never intersects with the axis of the oscillating water outlet 1.

[0030] It is understandable that when the second water-passing surface 27 is used as the water inlet surface, the water flow can directly pass through the rectifier 23 and flow through the second gap to impact the blade 12, causing the blade 12 to drive the oscillating water outlet 1 to rotate relative to the first rectifier cavity 22. Due to the setting of the first inner wall 20 and the existence of the side wall of the rectifier 23, some of the water flow is diverted through the first inner wall 20 and / or crosses the side wall of the rectifier 23, and then impacts the end face of the oscillating water outlet 1 or the blade 12 along the axial direction of the oscillating water outlet 1, applying axial pressure to the oscillating water outlet 1, so that the water outlet end of the oscillating water outlet 1 is tightly pressed against the inner wall of the first rectifier cavity 22, thereby increasing the rotation resistance and slowing down the rotation of the oscillating water outlet 1. At the same time, since the blade 12 of the oscillating water outlet 1 is in different positions at different times during rotation, the axial force applied to it causes the oscillating water outlet 1 to become unbalanced during rotation, causing its axis to be at an angle with the axis of the first rectifier cavity 22, and finally changing from rotation to oscillation, thus realizing oscillating water outlet. When the second water-passing surface 27 serves as the water inlet, the water flowing through the first and second gaps enters the third water-passing channel 11. When the oscillating water outlet 1 oscillates, the water flowing through the third water-passing channel 11 and oscillating outwards will acquire a spiral motion trajectory, thus producing a significant pulse-like rinsing effect on the washed surface. The design of the first and second gaps prevents the oscillating water outlet from directly contacting the side walls of the first inner wall 20 and the rectifier 23, thus avoiding rotational jamming or even stopping the oscillation, ensuring the smoothness and stability of the water flow. Besides the reasons mentioned above, the oscillating water outlet 1 may also experience rotational and oscillating jamming due to excessive impurities in the first rectifier cavity 22. To solve this problem, the oscillating water outlet 1 can be flipped so that the first water-passing surface 26 serves as the water inlet, thereby causing the water flow to reverse and rinse the first rectifier cavity 22, cleaning the first rectifier cavity 22 and ensuring the continuity of the pulsating water flow generated by the water outlet device.

[0031] Furthermore, when the second water-passing surface 27 serves as the water-inlet surface, there is a clearance gap L between the swinging water outlet 1 and the inner wall of the first rectifier cavity 22. The clearance gap L ensures that the swinging water outlet 1 deflects relative to the first rectifier cavity 22, thereby achieving the swinging motion.

[0032] In some embodiments, the water inlet 2 includes a first water passage 28 and a second water passage 29, with an inlet cavity 21 located between the first water passage 28 and the second water passage 29. A rectifier 23 is disposed on the second water passage 29. When the water outlet assembly is flipped relative to the main body 3, the axial positions of the first water passage 28 and the second water passage 29 change. The rectifier 23 ensures that either the first water passage 28 or the second water passage 29 can rectify and divert the water flow when either is used as the water inlet. A second water outlet 211 is provided on the first water passage 28. The second water outlet 211 can be coaxially disposed with the first water passage 28 or evenly distributed around the axis of the first water passage 28.

[0033] In some embodiments, the rectifier 23 has a guide channel 231 that communicates with the water inlet chamber 21 and the first rectifier chamber 22 respectively; the water outlet end of the guide channel 231 has a guide port 232, and the extension direction of at least one side wall of the guide channel 231 is arranged to avoid the axis of the first rectifier chamber 22, that is, the extension direction of at least one side wall of the guide channel 231 is arranged to avoid the axis of the first rectifier chamber 22. The guide channel 231 is provided to guide the water outflow direction. Specifically, the distance between the two opposite side walls of the guide channel 231 gradually decreases along the water inlet direction, and the two opposite side walls of the guide port 232 are distributed along the tangential direction of the swing water outlet 1, so that the water flowing out from the guide port 232 flows into the second gap along the tangential direction of the swing water outlet 1, thereby effectively impacting the blade 12 and providing a rotation driving force for the swing water outlet 1, driving the swing water outlet 1 to rotate continuously. The rectifier 23 includes multiple rectifiers arranged around the axis of the oscillating water outlet 1. The guide groove 231 and guide port 232 are formed between adjacent rectifiers. Preferably, there is a height difference between the end face of the rectifier 23 away from the first water outlet 221 and the end face of the blade 12. That is, in the axial direction of the oscillating water outlet 1, when the axis of the oscillating water outlet 1 coincides with the axis of the first rectifier cavity 22, the distance from the end face of the rectifier away from the first water outlet 221 to the water outlet end face of the first water outlet 221 is greater than the distance from the end face of the blade 12 away from the first water outlet 221 to the water outlet end face of the first water outlet 221. This allows the overflowing water flow to impact the end face of the blade 12, producing a rotational deceleration effect on the oscillating water outlet 1. In addition, in order to ensure the impact effect of the water flowing through the guide port 232 on the blade surface and end face of the blade 12, on the one hand, the guide port 232 is directly opposite the blade 12, and on the other hand, since there is a third water inlet 121 between adjacent blades 12 for water to enter the third water passage 11, there is a height difference between the surface of the guide port 232 near the first water inlet 221 and the surface of the third water inlet 121 near the first water inlet 221.

[0034] In some embodiments, at least three blades 12 are provided to form an impeller, and all blades 12 are equally spaced along the circumference of the oscillating water outlet 1; adjacent blades 12 have a third water inlet 121 for water to enter the third water passage 11. When the number of blades 12 is less than two, it may result in insufficient rotational driving force of the oscillating water outlet 1, or it may cause a force gap during the rotation of the oscillating water outlet 1 and stop rotating. If the number of blades 12 is too large, it may result in insufficient flow due to the total area of ​​the third water inlet 121 of the third water passage 11 being too small. Therefore, the number of blades 12 should be at least two but not more than eight. Optionally, four or five blades 12 can be provided to enable the oscillating water outlet 1 to obtain a sufficiently large and continuous rotational driving force. Furthermore, the number of guide channels 231 is always unequal to the number of blades 12 (when the number of guide channels 231 is odd, the number of blades 12 is even; when the number of guide channels 231 is even, the number of blades 12 is odd), ensuring that the impact of the water flow on the blades 12 is unbalanced at any given time. This allows the blades 12 to drive the oscillating water body 1 to oscillate within the first rectifying cavity 22, rather than simply moving around its axis. The purpose is to generate oscillating water splashes. Preferably, there are five blades 12, and correspondingly, six guide channels 231.

[0035] In some embodiments, the blade 12 has an impact surface 122 for being impacted by water flow. The impact surface 122 is distributed radially along the oscillating water outlet 1, so that the impact surface 122 can face the impact direction of the water flow substantially perpendicularly, ensuring the pressure efficiency of the water flow on the blade 12. In the axial direction of the oscillating water outlet 1, the projected area of ​​the blade 12 is L-shaped, and the impact surface 122 is located in the concave area of ​​the L-shape, so as to increase the pressure-bearing area of ​​the blade 12 within a limited space, thereby giving the blade 12 a good flow-blocking effect. The flow-blocking force will interact with the impact force of the water flow, thereby converting the impact force of the water flow into a driving force for the rotation of the oscillating water outlet 1, ensuring that the oscillating water outlet 1 continues to rotate.

[0036] In some embodiments, a first limiting surface 222 is provided inside the first rectifier cavity 22, and a support platform 13 is provided outside the swinging water outlet 1. When the second water-passing surface 27 serves as the water inlet surface, the support platform 13 only partially abuts against the first limiting surface 222 in the axial direction of the swinging water outlet 1, or there is a gap between the support platform 13 and the first limiting surface 222. In this embodiment, the first limiting surface 222 and the support platform 13 work together to maintain the existence of the first gap d and the second gap h. When the axis of the swinging water outlet 1 is at an angle of less than 9° with the axis of the first rectifier cavity 22, the swinging water outlet 1 can be partially pressed against the first limiting surface 222 by the support platform 13 to prevent the angle from continuing to increase and causing the blade 12 to collide with the side wall of the first inner wall 20 or the rectifier 23, thus stopping the swinging. Under normal swinging conditions, the axis of the swinging water outlet 1 and the axis of the first rectifier cavity 22 are generally in the range of 2° to 5°. When the oscillating water outlet 1 and the first rectifier cavity 22 are coaxial, there is a gap between the support platform 13 and the first limiting surface 222. At this time, the oscillating water outlet 1 can oscillate in any direction under the impact of the water flow. This design ensures that the oscillating water outlet 1 oscillates smoothly under the impact of the water flow, preventing it from getting stuck during oscillation and ensuring the smoothness of the water flow. Furthermore, a convex lip 223 can be added to the first limiting surface 222. Through the cooperation of the convex lip 223 and the support platform 13, while achieving the same function as the first limiting surface 222, the convex lip 223 can reduce the frictional area with the support platform 13, further reducing the probability of the oscillating water outlet 1 stopping oscillation.

[0037] In some embodiments, a second limiting surface 224 is provided near the water outlet end within the first rectifier cavity 22, and the second limiting surface 224 is an arc surface. When the second water-passing surface 27 serves as the water inlet surface, the water outlet end of the oscillating water outlet 1 presses against the second limiting surface 224. The pressing position between the oscillating water outlet 1 and the second limiting surface 224 is variable, meaning that the water outlet end of the oscillating water outlet 1 can change its relative position with the first rectifier cavity 22 along the arc surface of the second limiting surface 224, thereby further ensuring that the oscillating water outlet 1 can smoothly generate oscillation within the first rectifier cavity 22 and improving the smoothness of the oscillating water outlet. In other similar embodiments, the outer wall curvature of the water outlet end of the oscillating water outlet 1 is designed to only generate line contact or even point contact with the inner wall of the arc surface of the second limiting surface 224. This can further reduce the friction area between the two and ensure the smooth oscillation of the oscillating water outlet 1.

[0038] In some embodiments, a support member 25 is embedded in the first rectifier cavity 22, the second limiting surface 224 is located within the support member 25, and the first water passage hole 221 is also located at the end of the support member 25. The support member 25 is a compromise solution adopted to address the difficulty of directly molding the second limiting surface 224 when injection molding the water inlet body 2. That is, the water inlet body 2 without the second limiting surface 224 is first molded in the first rectifier cavity 22, and then the support member 25 with the second limiting surface 224 is injection molded as an independent part. Finally, the support member 25 is embedded in the first rectifier cavity 22.

[0039] In some embodiments, the diameter of the third water passage 11 gradually decreases in the direction away from the blade 12, so as to pressurize the water flow within the third water passage 11, thereby ultimately forming a water flow with a better massage effect. In addition, the third water passage 11 can also be eccentrically arranged within the water outlet 1, so that the discharged water flow has a larger oscillation range.

[0040] In some embodiments, when the second water-passing surface 27 serves as the water-inlet surface, a first distance k exists between the upper end face of the first rectifying cavity 22 and the water-inlet end of the first water-passing port 221 along the axial direction of the swinging water-outlet body 1, and the ratio of the height g of the swinging water-outlet body 1 to the first distance k is 1:1 to 1:1.2. Preferably, the ratio of the height g of the swinging water-outlet body 1 to the first distance k is 1:1, 1:1.1, or 1:1.2. Limiting the height ratio between the oscillating water outlet 1 and the first rectifier cavity 22 essentially limits the height of the oscillating water outlet 11. If the height of the oscillating water outlet 1 is too high compared to the height of the first rectifier cavity 22, it will be difficult to generate effective oscillation in the first rectifier cavity 22, and no obvious oscillating water outlet will be generated. In addition, the blades 12 of the oscillating water outlet 1 are also prone to interference with other structures, resulting in the inability to oscillate continuously. Conversely, if the height of the oscillating water outlet 1 is too small compared to the height of the first rectifier cavity 22, on the one hand, the blades 12 may be set too short in proportion and cannot receive the drive of the water flow well, thus affecting the continuity of the oscillation of the oscillating water outlet 1. On the other hand, if the oscillating water outlet 1 is too short as a whole, it may generate an excessively large oscillation angle, which will affect the normal water outlet effect.

[0041] In some embodiments, when the second water-passing surface 27 serves as the water inlet surface, the ratio of the height of the blade 12 to the height of the oscillating water outlet 1 in the axial direction of the oscillating water outlet 1 is 1:1.5 to 1:3. When this ratio is too small, the oscillation angle of the oscillating water outlet 1 will be too small, failing to produce a noticeable oscillating water outlet, thus affecting the pulsating and massaging effects of the water flow; when this ratio is greater than 1:3, the blade 12 will be too short to receive the drive of the water flow well, resulting in a decrease in the smoothness of the rotation of the oscillating water outlet 1. Therefore, preferably, the ratio of the height of the blade 12 to the height of the oscillating water outlet 1 is 1:2.

[0042] In some embodiments, when the second water-passing surface 27 serves as the water inlet surface, a second rectifying cavity 24 is provided downstream of the first water outlet 221. When the axis of the swinging water outlet 1 forms an angle with the axis of the first rectifying cavity 22, the water flow discharged by the swinging water outlet 1 can collide with the inner wall of the second rectifying cavity 24, causing the water flow about to be discharged to the outside to be reshaped by the second rectifying cavity 24. Depending on the different shapes of the second rectifying cavity 24, different shaping effects are produced on the discharged water flow, resulting in different water spray patterns, thus enhancing the richness of product functions. When the first water-passing surface 26 serves as the water inlet surface, the second rectifying cavity 24 is located upstream of the first water outlet 221.

[0043] In some embodiments, when the second water-passing surface 27 serves as the water inlet surface: the cross-sectional area of ​​the water inlet end of the first water outlet 221 is greater than 70% of the cross-sectional area of ​​the drain outlet of the third water-passing channel 11. When the cross-sectional area of ​​the water inlet end of the first water outlet 221 is 70% to 100% of the cross-sectional area of ​​the drain outlet of the third water-passing channel 11, the first water outlet 221 will interfere with the water flow that is about to be discharged to the outside together with the second rectifier cavity 24, and can achieve the effect of making the fluid droplets of the water flow collide and break each other inside the fluid to produce water splash granulation. Finally, it can output oscillating granular water splashes, which can further improve the massage effect and rinsing efficiency. When the area of ​​the water inlet end of the first water outlet 221 is greater than the area of ​​the drain outlet of the third water-passing channel 11, the interference effect of the first water outlet 221 on the water flow that is about to be discharged to the outside is weakened or there is no interference effect, resulting in a smoother drainage effect. It should be noted that if the inlet area of ​​the first water outlet 221 is less than 70% of the outlet cross-sectional area of ​​the third water passage 11, the water flow will be obstructed due to excessive interference, and the water flow may accumulate in the third water passage 11 and generate a large water pressure. The water pressure will be transmitted upstream, causing the swinging water body 1 to stop rotating. Therefore, in order to balance the smooth swinging of the swinging water body 1 and the diversity of water splashes brought about by moderate interference, this ratio can preferably be set to the inlet cross-sectional area of ​​the first water outlet 221 being 85% to 95% of the outlet cross-sectional area of ​​the third water passage 11.

[0044] In some embodiments, the drain outlet area of ​​the third water passage 11 is 0.7 mm². 2 ~20mm 2 The size range is designed to take into account the water pressure supply conditions in a home environment, allowing the water outlet components to produce a better bathing experience and rinsing effect. Specifically, a smaller drain outlet area is prone to problems with water flow and the drain outlet is easily clogged by impurities; conversely, a larger water outlet area is not supported by normal water pressure supply conditions, making it difficult to achieve the set water flow effect (for example, insufficient pressure makes it difficult to produce granular water spray, or the impact of granular water spray is significantly weakened).

[0045] In some embodiments, the longitudinal section of the second rectifier cavity 24 is trapezoidal or quadrilateral; or, the second rectifier cavity 24 is frustum-shaped, cylindrical, elliptical frustum-shaped, or truncated pyramidal. Specifically, in terms of the shape of the longitudinal section, the trapezoidal longitudinal section can have the distance between the two sides gradually increasing along the water outlet direction to expand the water outlet swing area, or conversely, the distance between the two sides can gradually decrease along the water outlet direction to reduce the swing area and collect the water flow to achieve a pressurization effect; the quadrilateral longitudinal section is square or rectangular, allowing the water flow to form a splash that swings along the circumference; in terms of the three-dimensional shape of the second rectifier cavity 24, the frustum-shaped second rectifier cavity 24 can have the water outlet area gradually increasing along the water outlet direction to expand the water outlet swing area, or conversely, the water outlet area can gradually decrease along the water outlet direction to reduce the swing area and collect the water flow to achieve a pressurization effect; the quadrilateral longitudinal section is square or rectangular, allowing the water flow to form a splash that swings along the circumference; The area gradually decreases along the water outlet direction to reduce the oscillation area and collect the water flow to achieve the effect of pressurization; the elliptical frustum-shaped second rectifier cavity 24 can have a water outlet area that gradually decreases along the water outlet direction, allowing the water flow to be discharged in a flat fan shape in a reciprocating oscillation pattern; similar to the elliptical frustum-shaped second rectifier cavity 24, the water outlet area can also gradually decrease along the water outlet direction, allowing the water flow to be discharged in a flat fan shape in a reciprocating oscillation pattern; in other embodiments, the shape of the second rectifier cavity 24 can also be between the elliptical frustum and the square frustum, that is, a square frustum with rounded corners at the edges.

[0046] Please refer to Figures 1-6 Embodiment 1 of this utility model is as follows: A water outlet device includes: a swinging water outlet body 1, a water inlet body 2, and a main body 3; the main body 3 has a water outlet 31; the water inlet body 2 is rotatably disposed within the water outlet 31; the water inlet body 2 has a water inlet cavity 21, a first water passage surface 26, a second water passage surface 27, a first rectifier cavity 22, and a first water passage channel and a second water passage channel communicating with the first rectifier cavity 22, the first rectifier cavity 22 having a first water passage 221; the swinging water outlet body 1 has a third water passage channel 11 communicating with the water inlet cavity 21 and the first water passage 221 respectively ...6, the first water passage 26, the second water passage 27, the third water passage 27, the third water passage 27, the fourth water passage 27, the fifth water passage 27, the sixth water passage 27, the seventh water passage 27, the The water body 1 is oscillatingly disposed within the first rectifier cavity 22. The oscillating water body 1 can guide the water flow leaving the outlet 31 to be discharged along a spiral motion trajectory. When the first water-passing surface 26 serves as the water inlet surface, a flushing channel 14 is formed between the oscillating water body 1 and the inner wall of the first rectifier cavity 22. The flushing channel 14 provides water flow that impacts the inner wall of the first rectifier cavity 22. When the second water-passing surface 27 serves as the water inlet surface, the first water-passing channel provides water flow that laterally impacts the oscillating water body 1, and the second water-passing channel provides water flow that axially impacts the oscillating water body 1. The inlet end of the oscillating water outlet 1 is provided with blades 12. When the first water-passing surface 26 serves as the inlet surface, in the axial direction of the oscillating water outlet 1, a first gap d is formed between the inlet end of the oscillating water outlet 1 and the first inner wall 20 inside the inlet cavity 21. The first gap d is located on the second water-passing channel, and the projection area of ​​the third water-passing channel 11 is located on the first inner wall 20, so that the water flow at least bypasses part of the third water-passing channel 11 to impact the oscillating water outlet 1 or the blades 12. In the transverse direction of the oscillating water outlet 1, a second gap h is formed between the blades 12 and the side wall of the rectifier 23. The second gap h is located on the first water-passing channel, and the second gap h allows the water flow to pass through the rectifier 23 and the second gap h in sequence before impacting the oscillating water outlet 1 or the blades 12 radially. In this embodiment, there is a clearance gap L between the oscillating water outlet 1 and the inner wall of the first rectifier cavity 22 to ensure that the oscillating water outlet 1 oscillates and rotates smoothly within the first rectifier cavity 22.

[0047] In this embodiment, the water inlet 2 includes a first water passage component 28 and a second water passage component 29. The water inlet cavity 21 is located between the first water passage component 28 and the second water passage component 29. The rectifier 23 is disposed on the second water passage component 29. When the water outlet assembly is flipped relative to the main body 3, the axial positions of the first water passage component 28 and the second water passage component 29 change. A second water outlet 211 is provided on the first water passage component 28, and the second water outlet 211 is coaxially disposed with the first water passage component 28.

[0048] It is worth noting that when the first water-passing surface 26 is used as the water inlet surface, the swinging water outlet 1 presses against the first inner wall 20, that is, against the second water-passing component 29. When the second water-passing surface 27 is used as the water inlet surface, the swinging water outlet 1 presses against the first water-passing component 28.

[0049] In this embodiment, the rectifier 23 has a guide channel 231 that communicates with the water inlet chamber 21 and the first rectifier chamber 22 respectively; the water outlet end of the guide channel 231 has a guide port 232, and the extension direction of at least one side wall of the guide channel 231 is arranged to avoid the axis of the first rectifier chamber 22, that is, the extension direction of at least one side wall of the guide channel 231 is arranged to avoid the axis of the water inlet body 2; the distance between the two opposite side walls of the guide channel 231 gradually decreases along the water inlet direction, and the two opposite side walls of the guide port 232 are distributed along the tangential direction of the swinging water outlet body 1. The rectifier 23 includes a plurality of rectifiers arranged around the axis of the oscillating water outlet 1. The aforementioned guide groove 231 and guide port 232 are formed between adjacent rectifiers. Preferably, when the second water passage surface 27 is used as the water inlet surface, there is a height difference between the end face of the rectifier away from the first water passage 221 and the end face of the blade 12. That is, in the axial direction of the oscillating water outlet 1, when the axis of the oscillating water outlet 1 coincides with the axis of the first rectifier cavity 22, the distance from the end face of the rectifier away from the first water passage 221 to the water outlet end face of the first water passage 221 is greater than the distance from the end face of the blade 12 away from the first water passage 221 to the water outlet end face of the first water passage 221.

[0050] In this embodiment, five blades 12 are provided, and correspondingly, six guide channels 231 are provided. All blades 12 are arranged at equal intervals along the circumference of the swinging water body 1. There is a third water inlet 121 between adjacent blades 12 for water to flow into the third water passage 11.

[0051] In this embodiment, the blade 12 has an impact surface 122 for being impacted by water flow, and the impact surface 122 is distributed radially along the oscillating water body 1; in the axial direction of the oscillating water body 1, the projected area of ​​the blade 12 is L-shaped, and the impact surface 122 is located in the concave area of ​​the L-shape.

[0052] In this embodiment, a first limiting surface 222 is provided in the first rectifier cavity 22, and a convex lip 223 is provided on the first limiting surface 222; a support platform 13 is provided outside the water inlet end of the swing water body 1; when the second water passage surface 27 is used as the water inlet surface, the support platform 13 and the convex lip 223 press against each other in the axial direction of the water inlet body 2.

[0053] In this embodiment, a second limiting surface 224 is provided in the water outlet end of the first rectifier cavity 22, and the second limiting surface 224 is an arc surface. When the second water passage surface 27 is used as the water inlet surface, the water outlet end of the swing water outlet 1 presses against the second limiting surface 224, and the pressing position between the swing water outlet 1 and the second limiting surface 224 is variable.

[0054] In this embodiment, the diameter of the third water passage 11 gradually decreases in the direction away from the blade 12.

[0055] In this embodiment, when the second water-passing surface 27 is used as the water-inlet surface, there is a first distance k between the upper end surface of the first rectifier cavity 22 and the water inlet end of the first water-passing port 221 in the axial direction of the swing water-outlet body 1, and the ratio of the height g of the swing water-outlet body 1 to the first distance k is 1:1.1.

[0056] In this embodiment, when the second water-passing surface 27 is used as the water-inlet surface, the ratio of the height of the blade 12 to the height of the swinging water-outlet body 1 in the axial direction of the swinging water-outlet body 1 is 1:2.

[0057] In this embodiment, when the second water inlet surface 27 is used as the water inlet surface, a second rectifier cavity 24 is provided downstream of the first water outlet 221. When the axis of the swinging water outlet 1 forms an angle with the axis of the first rectifier cavity 22, the water flow discharged by the swinging water outlet 1 can collide with the inner wall of the second rectifier cavity 24.

[0058] In this embodiment, the cross-sectional area of ​​the inlet end of the first water outlet 221 is 85% to 95% of the cross-sectional area of ​​the outlet end of the third water passage 1111.

[0059] In this embodiment, the drainage outlet area of ​​the third water passage 11 is 0.7 mm². 2 ~20mm 2 .

[0060] In this embodiment, when the second water-passing surface 27 is used as the water inlet surface, the longitudinal section of the second rectifier cavity 24 is a trapezoid with the distance between the two waists gradually increasing along the water outlet direction.

[0061] The working principle of this embodiment is as follows: When the second water-passing surface 27 serves as the water inlet surface, a portion of the water flow enters the water inlet chamber 21 from the second water outlet 211. The water flowing through the guide port 232 impacts the blades 12 laterally along the swinging water outlet 1, causing the swinging water outlet 1 to rotate. Another portion of the water flow directly impacts the blades 12 and the swinging water outlet 1 axially. The swinging water outlet 1 decelerates and maintains rotation after being subjected to axial pressure. Specifically, when the swinging water outlet 1 and the water inlet 2 are coaxial, the first inner wall 20 has the largest obstruction area for the third water passage 11, resulting in the smallest water flow. When the axis of the swinging water outlet 1 and the axis of the water inlet 2 form an angle of approximately 5°, the first inner wall 20 has the smallest obstruction area for the third water passage 11, resulting in the largest water flow. Therefore, because the swinging water outlet 1 swings back and forth under the impact of the water flow, it creates a water flow with fluctuating flow rates and a massaging effect.

[0062] When the first water inlet 26 is used as the water inlet, the water flows in from the first water outlet 221 and is diverted by the swinging water outlet 1, so that part of the water flows through the third water inlet 11 and the other part flows through the flushing channel 14. Impurities will be mixed into the water flow and discharged from the second water outlet 211.

[0063] Please refer to Figure 7 Embodiment two of this utility model is as follows: The difference between this embodiment and Embodiment 1 is that the structure of the first water inlet 221 is different.

[0064] In this embodiment, the longitudinal section of the first water outlet 221 is rectangular.

[0065] Please refer to Figures 8-11 Embodiment three of this utility model is as follows: The difference between this embodiment and Embodiment 1 is that the structure of the first water outlet 221 is different, and a support member 25 is provided.

[0066] In this embodiment, when the second water-passing surface 27 is used as the water inlet surface, the longitudinal section of the second rectifier cavity 24 is a trapezoid with the distance between the two waists gradually decreasing along the water outlet direction.

[0067] In this embodiment, a support member 25 is provided inside the first rectifier cavity 22; the outlet end of the swing water outlet body 1 is embedded in the support member 25, and when the second water passage surface 27 serves as the water inlet surface, a portion of the swing water outlet body 1 presses against the support member 25. Specifically, when the support member 25 is provided inside the first rectifier cavity 22, the first limiting surface 222, the second limiting surface 224, and the convex lip 223 are all located on the support member 25, and the first water passage hole 221 is also located at the end of the support member 25.

[0068] The water flow pattern formed in this embodiment is a rotating massage particle water to achieve a point massage effect, and its water outlet range is smaller than that in Embodiment 1.

[0069] Please refer to Figures 12-14 Embodiment four of this utility model is as follows: The difference between this embodiment and Embodiment 3 is that the location of the second water outlet 211 is different.

[0070] In this embodiment, the second water inlet 211 is evenly distributed around the axis of the water inlet body 2, so that the water flows into the water inlet cavity 21 along the radial direction of the water inlet body 2.

[0071] In this embodiment, the longitudinal section of the second rectifier cavity 24 is a trapezoid with the distance between the two waists gradually decreasing along the water outlet direction, and its overall shape is a truncated square.

[0072] The working principle of this embodiment is as follows: When the second water-passing surface 27 is used as the water inlet surface, the water flows into the water inlet chamber 21 from the second water-passing port 211. Most of the water flow will impact the blades 12 laterally along the swinging water outlet 1, causing the swinging water outlet 1 to rotate. A small portion of the water flow will directly impact the blades 12 and the swinging water outlet 1 axially. After being subjected to axial pressure, the swinging water outlet 1 decelerates and maintains a slow rotation.

[0073] In summary, this invention guides the water flow acting on the oscillating water outlet and controls the contact area between the oscillating water outlet and the inlet body, ensuring that the resistance during the rotation of the oscillating water outlet always guarantees that it can rotate smoothly at an appropriate speed, generating a water flow with pulsating and massaging effects. Furthermore, the reversible connection between the inlet body and the main body enables reverse flushing of the first rectifier chamber, ensuring the smoothness of the oscillating water outlet's movement and guaranteeing a continuous and smooth flow of massage water.

[0074] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
