[0002] This invention relates to the field of bathroom products technology, and in particular to a water outlet device. Background Technology

[0003] Water outlet devices with temperature control functions typically have cold water inlets and hot water inlets. The outlet water temperature is changed by adjusting the ratio of cold and hot water using a water temperature regulating device, such as a valve core. Specifically, the movable valve plate of the valve core can be rotated to change the flow area of ​​cold and hot water between the movable and stationary valve plates, thereby altering the ratio of the two types of water entering the mixing space and thus changing the outlet water temperature. However, during the adjustment process, the two valve plates rotate relative to each other for extended periods and experience friction, which can easily lead to valve plate wear, resulting in cross-contamination and affecting the accuracy of the outlet water temperature regulation. Summary of the Invention

[0004] This invention proposes a water outlet device to solve the technical problem in the prior art where the water temperature regulation device in the water outlet device is easily worn, leading to water leakage and affecting the accuracy of water temperature regulation.

[0005] To achieve the above objectives, some embodiments of the present invention provide a water outlet device, comprising:

[0016] According to some embodiments of the present invention, a first switching component is disposed in the water passage cavity. The first switching component includes an impeller and a first water baffle. The impeller is used to rotate under the impact of water flow, thereby driving the first water baffle to rotate.

[0041] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] refer to Figure 1 In some specific embodiments of the present invention, a water outlet device 1000 is provided, which can automatically realize alternating hot and cold water output. It can be applied to scenarios such as bathroom showers or kitchen water use. For example, the water outlet device 1000 can be a component of water outlet equipment such as handheld shower heads, overhead shower heads, spray guns, and faucets. Cold water and hot water enter the water outlet device 1000 through different inlet pipes, and can realize automatic alternating hot and cold water output. The automatic alternating hot and cold water output means that the user does not need to constantly manually switch between cold and hot water inlets; the circulating alternating hot and cold water output can be automatically realized, thereby achieving a stimulating effect on the human body.

[0043] refer to Figures 1-4 The water outlet device 1000 of this embodiment includes a housing 100 and a first switching component 200. The housing 100 is provided with a water inlet channel, a water passage chamber 120, and a water outlet channel connected in sequence. The water inlet channel includes a first water inlet channel 111 and a second water inlet channel 112. The first water inlet channel 111 is connected to the water passage chamber 120 through a first water outlet 1111, and the second water inlet channel 112 is connected to the water passage chamber 120 through a second water outlet 1121. The water passage chamber 120 is connected to the water outlet channel through a third water outlet 141. Thus, hot and cold water can flow through the first water inlet channel 111 and the second water inlet channel 112, respectively, and after passing through the first water outlet 1111 and the second water outlet 1121, enter the water passage chamber 120, and then flow out through the third water outlet 141 and the water outlet channel for showering. The first switching component 200 is disposed in the water passage chamber 120 and includes an impeller 210 and a first water baffle 220. When cold water and / or hot water enter the water passage chamber 120, they will impact the impeller 210 and make it rotate. The impeller 210 will drive the first water baffle 220 to rotate. During the rotation, the first water baffle 220 is used to block or open the first water passage 1111 and the second water passage 1121.

[0044] The first water inlet channel 111 can be a cold water channel and the second water inlet channel 112 a hot water channel, or the first water inlet channel 111 can be a hot water channel and the second water inlet channel 112 a cold water channel. The following explanation uses the example of the first water inlet channel 111 being a cold water channel and the second water inlet channel 112 being a hot water channel: When the first water baffle 220 blocks the first water outlet 1111, the cold water inlet is closed and the hot water inlet is opened. The hot water flows out sequentially through the second water inlet channel 112, the second water outlet 1121, the water passage 120, the third water outlet 141, and the outlet channel. When the first water baffle 220 rotates to block the second water outlet 1121, the hot water inlet is closed and the cold water inlet is opened. The cold water flows out from the outlet channel. It is understandable that there is also a situation where the first water baffle 220 simultaneously opens both the first water outlet 1111 and the second water outlet 1121.

[0045] Therefore, the impeller 210 can be driven to rotate by the water flow, which in turn causes the first water baffle 220 to rotate automatically in a cycle, repeatedly blocking and opening the first water inlet 1111 and the second water inlet 1121, thereby achieving the purpose of alternating hot and cold water circulation and stimulating the human body, without the need for manual adjustment by the user.

[0046] refer to Figure 4 In some embodiments of the present invention, the first water-blocking component 220 has a fan-shaped structure, wherein the fan shape is radiating outward from the rotation axis of the impeller 210 along the circumferential direction of the impeller 210, and the angle of the fan shape can be 180°. Thus, during rotation, the first water-blocking component 220 always keeps one of the first water inlet 1111 and the second water inlet 1121 open while blocking the other, ensuring a constant flow of either cold or hot water. This avoids the mixing of cold and hot water within the water passage cavity 120 or the simultaneous blocking of both cold and hot water, preventing water from flowing out. In this case, the user can enjoy the alternating stimulation of extremely cold and extremely hot water.

[0047] In some embodiments of the present invention, the first water-blocking component 220 has a fan-shaped structure, wherein the fan shape is radiating outwards from the rotation axis of the impeller 210 in the circumferential direction, and the angle of the fan shape is less than 180°. Since alternating showers with extremely cold and hot water can stimulate rapid expansion and contraction of blood vessels, elderly people, children, or patients with special physical conditions may not adapt well to such extreme temperature changes, and it may even have the opposite stimulating effect. Therefore, the angle of the first water-blocking component 220 is designed to be less than 180°. When the first water-blocking component 220 rotates, in addition to blocking the first water inlet 1111 or the second water inlet 1121, there is also a position where the first water inlet 1111 and the second water inlet 1121 are simultaneously open. At this time, cold and hot water can simultaneously enter the water passage chamber 120 for mixing, forming a mixed warm water with a temperature higher than cold water but lower than hot water. (Reference) Figure 13Taking the fan-shaped angle of the first water baffle 220 as 72° as an example, when the water outlet device 1000 is opened, the water flow impacts the impeller 210, causing the first water baffle 220 to rotate. At this time, the water outlet time of different temperatures is cold water: warm water: hot water = 72°: 216°: 72° = 1: 3: 1. That is, at a certain water outlet time ratio, a circulating cold-warm-hot water outlet effect is presented. Therefore, when special groups of people enjoy the stimulation of alternating hot and cold water, an additional warm water transition stage is added, thereby avoiding the discomfort caused by drastic water temperature changes between extremely cold and extremely hot water.

[0048] Understandably, the fan-shaped design of the first water baffle 220 can be designed with various angles, which can be changed according to the user's different physical condition or needs. For example, when the user wants to enjoy the extreme cold or heat stimulation for a longer period of time, the fan-shaped angle can be increased, thereby reducing the warm water output time. Conversely, the fan-shaped angle can be decreased to increase the warm water output time and reduce the intensity of water stimulation.

[0049] refer to Figure 3 and Figure 4 In some embodiments of the present invention, the housing 100 further includes a switching cavity 113, the extension direction of which is perpendicular to the axis of the water inlet channel and connects the first water inlet channel 111 and the second water inlet channel 112. The water outlet device 1000 further includes a second switching component 300, which is disposed within the switching cavity 113 and can slide relative to the switching cavity 113. The second switching component 300 is provided with a first through hole 311 and a second through hole 321. The first through hole 311 connects the first water inlet channel 111 and the water passage cavity 120, and the second through hole 321 connects the second water inlet channel 112 and the water passage cavity 120. When the second switching component 300 slides within the switching cavity 113, it can change the water flow area between the first through hole 311 and the first water inlet channel 111, and the water flow area between the second through hole 321 and the second water inlet channel 112, thereby changing the flow rate of cold and hot water during alternating showers.

[0050] Specifically, the second switching component 300 can be manually operated by the user, such as pushing or pulling the second switching component 300 along the extension direction of the switching cavity 113 so that it can slide relative to the switching cavity 113, or it can be driven by a motor, with the user selecting different functions through a control switch, and the central control component controlling the motor to drive the second switching component 300 to slide.

[0051] The following is a further description of this embodiment: the second switching component 300 can slide to different positions relative to the switching cavity 113:

[0052] When the second switching component 300 slides to the first position, refer to Figure 8(The dotted lines with arrows in the diagram indicate the direction of water flow.) The water flow area between the first through hole 311 and the first water inlet channel 111 is the largest, while the water flow area between the second through hole 321 and the second water inlet channel 112 is zero. At this time, the water outlet device 1000 can only pass through and flow out cold water. At this time, the first switching component 200 rotates in the water passage chamber 120 as the water flow impacts. When the first water baffle 220 blocks the second water outlet 1121, it does not affect the cold water output. At this time, the water outlet device 1000 outputs cold water. When it rotates to block the first water outlet 1111, no cold or hot water passes through the water passage chamber 120. At this time, the water outlet device 1000 does not output water, and the impeller 210 continues to rotate until the first water baffle 220 reopens the first water outlet 1111, and the water outlet device 1000 outputs cold water again. Thus, the cold water is output in an intermittent pulse, which can achieve a massage effect on the human body.

[0053] When the second switching component 300 slides to the second position, refer to Figure 9 (The dotted line with arrows in the figure indicates the direction of water flow). At this time, the hot water connection area is the largest, and the cold water connection area is 0. The water outflow process is the same as in the first position above, realizing the intermittent pulse water outflow with a massage effect.

[0054] When the second switching component 300 slides to the third position, refer to Figure 10 (The dotted lines with arrows in the diagram indicate the direction of water flow.) At this time, the water-passing area between the first through hole 311 and the first water inlet channel 111, and the connecting area between the second through hole 321 and the second water inlet channel 112, are both not zero. Therefore, both cold and hot water can enter the water passage 120. When the angle of the fan-shaped first water baffle 220 is 180°, during the rotation of the first water baffle 220, one of the first water inlet channel 111 and the second water inlet channel 112 remains connected while the other is closed, thus allowing for alternating cold and hot water flow. When the angle of the fan-shaped first water baffle 220 is less than 180° (e.g., 72°), alternating cold, warm, and hot water flow occurs.

[0055] Furthermore, when the second switching component 300 is in the third position, the user can also slide the second switching component 300 as needed to increase the water flow area between the first through hole 311 and the first water inlet channel 111, while reducing the water flow area between the second through hole 321 and the second water inlet channel 112. This increases the cold water flow rate while decreasing the hot water flow rate during the alternating water output process. This cycle provides the user with a pulse massage effect of high cold water flow rate and low hot water flow rate during the alternating cold-hot or cold-warm-hot water output stimulation of the human body. Understandably, the user can also adjust it in the opposite direction to achieve a pulse massage effect of low cold water flow rate and high hot water flow rate.

[0056] refer to Figure 3 , Figure 4In some embodiments of the present invention, the housing 100 further includes a switching cavity 113, the extending direction of which is perpendicular to the axis of the water inlet channel and connects the first water inlet channel 111 and the second water inlet channel 112. The water outlet device 1000 further includes a second switching component 300, which is disposed in the switching cavity 113 and is rotatable relative to the switching cavity about the axis of the switching cavity 113. The second switching component 300 is provided with a first through hole 311 and a second through hole 321. The first through hole 311 is used to connect the first water inlet channel 111 and the water passage cavity 120, and the second through hole 321 is used to connect the second water inlet channel 112 and the water passage cavity 120. Specifically, when the second switching component 300 rotates in the switching cavity 113, it can change the water flow area between the first through hole 311 and the first water inlet channel 111, and / or the water flow area between the second through hole 321 and the second water inlet channel 112, so as to change the flow rate of cold and hot water entering the water passage cavity 120.

[0057] Specifically, the second switching component 300 can be manually operated by the user to rotate relative to the switching cavity 113, or it can be driven by a motor, with the user selecting different functions through a control switch, and the central control component controlling the motor to drive the second switching component 300 to rotate.

[0058] For example, the user can rotate the second switching component 300 to reduce the water flow area between the first through hole 311 and the first water inlet channel 111, as well as the water flow area between the second through hole 321 and the second water inlet channel 112, thereby reducing the flow rate of cold and hot water entering the water passage 120 and thus regulating the alternating water flow rate.

[0059] refer to Figure 3 , Figure 4 and Figure 6 In some embodiments of the present invention, the second switching assembly 300 is formed by splicing a first switching shaft 310 and a second switching shaft 320. A first through hole 311 is provided on the first switching shaft 310, and a second through hole 321 is provided on the second switching shaft 320. A first connecting portion 312 is provided on one end of the first switching shaft 310 near the second switching shaft 320, and a second connecting portion 322 is provided on one end of the second switching shaft 320 near the first switching shaft 310. The first switching shaft 310 and the second switching shaft 320 are pivotally connected through the first connecting portion 312 and the second connecting portion 322. The aforementioned pivot connection means that both the first switching shaft 310 and the second switching shaft 320 can rotate independently around the axis of the switching cavity 113, that is, either the first switching shaft 310 or the second switching shaft 320 can be rotated independently.

[0060] Specifically, one of the first connecting part 312 and the second connecting part 322 can be a universal ball joint, and the other is a groove adapted to the universal ball joint. The first connecting part 312 and the second connecting part 322 can also be connected by a bearing structure, which is not limited here, as long as the two can connect the first switching shaft 310 and the second switching shaft 320 and can rotate independently around the axis of the switching cavity 113.

[0061] Therefore, users can choose to rotate the first switching shaft 310 or the second switching shaft 320 according to their needs, thereby changing the flow ratio of cold water and hot water entering the water passage 120.

[0062] The following example illustrates this embodiment by keeping the water passage area between the second through hole 321 and the second water inlet channel 112 constant (for example, keeping the hot water passage area at its maximum):

[0063] refer to Figure 11 Rotate the first switching shaft 310 so that the first through hole 311 and the first water inlet channel 111 are completely aligned. At this time, the water flow area between the two is at its maximum, and the amount of cold water and hot water entering the water passage 120 reaches its maximum. When the fan angle of the first water baffle 220 is 180°, the alternating cold water and hot water reach their maximum flow rate; when the fan angle of the first water baffle 220 is less than 180° (such as 72°), the alternating cold water, warm water and hot water all reach their maximum flow rate.

[0064] refer to Figure 12 Continue rotating the first switching shaft 310 until the first through hole 311 and the first water inlet channel 111 only partially overlap. At this point, the water passage area between the first through hole 311 and the first water inlet channel 111 decreases, resulting in a lower flow rate of cold water into the water passage chamber 120 compared to the hot water flow rate. When the fan-shaped angle of the first water baffle 220 is 180°, the cold water flow rate is lower than the hot water flow rate during the alternating hot and cold water output, thus creating a pulse massage effect. When the fan-shaped angle of the first water baffle 220 is less than 180° (e.g., 72°), it produces alternating cold-warm-hot water output. Since the cold water flow rate is lower than the hot water flow rate, the alternating water output process not only produces a pulse-like massage effect, but the warm water temperature is also higher than... Figure 11 The temperature of the warm water when the cold water flow rate entering the water passage 120 is at its maximum is shown.

[0065] Therefore, users can adjust the flow rate of cold and hot water entering the water chamber 120 by rotating the first switching shaft 310 or the second switching shaft 320, so as to achieve a pulse massage effect by alternating hot and cold water output, or to adjust the temperature of warm water while achieving a pulse massage effect during the alternating hot-cold-warm-hot water output process, so as to better meet the user's personalized needs.

[0066] refer to Figure 3 and Figure 4 In some embodiments of the present invention, a first operating part 313 is provided on the end of the first switching shaft 310 away from the second switching shaft 320, and a second operating part 323 is provided on the end of the second switching shaft 320 away from the first switching shaft 310. The first operating part 313 and the second operating part 323 can be a handwheel, a knob, etc. The user can push or pull the first operating part 313 or the second operating part 323 to allow the second switching assembly 300 to slide within the switching cavity 113. The user can also rotate the first operating part 313 and the second operating part 323 to allow the first switching shaft 310 and / or the second switching shaft 320 to rotate within the switching cavity 113.

[0067] refer to Figure 3 , Figure 4 and Figure 5 In some embodiments of the present invention, a first pin hole 314 is provided on the first switching shaft 310, and a first positioning pin 410 is inserted into the first pin hole 314. A second pin hole 324 is provided on the second switching shaft 320, and a second positioning pin 420 is inserted into the second pin hole 324. The second switching assembly 300 can slide relative to the switching cavity 113. It can be understood that the second switching assembly 300 can slide relative to the switching cavity 113, rotate relative to the switching cavity 113, or rotate while sliding. The switching cavity 113 is provided with a first positioning part 1131 and a second positioning part (not shown) at both ends. The first positioning part 1131 is located between the first water inlet channel 111 and the first operating part 313. When the second switching component 300 slides relative to the switching cavity 113, the first positioning part 1131 cooperates with the first positioning pin 410 to limit the sliding of the second switching component 300. The second positioning part is located between the second water inlet channel 112 and the second operating part 323. The second positioning part cooperates with the second positioning pin 420 to limit the sliding of the second switching component 300.

[0068] Specifically, the first positioning part 1131 and the second positioning part can be a boss, annular rib, or the like protruding from the inner wall of the switching cavity 113. The orientation of the platform of the positioning part that abuts against the positioning pin is parallel to the sliding direction of the second switching assembly 300. When the user pushes or pulls the first operating part 313 or the second operating part 323 to make the second switching assembly 300 slide within the switching cavity 113, the first positioning part 1131 and the second positioning part can stop the first positioning pin 410 and the second positioning pin 420 in a preset position, thereby limiting the sliding of the second switching assembly 300 and keeping the change in the hot and cold water flow area within a preset range.

[0069] refer to Figure 3 , Figure 4 and Figure 5In some embodiments of the present invention, a first pin hole 314 is provided on the first switching shaft 310, and a first positioning pin 410 is inserted into the first pin hole 314. A second pin hole 324 is provided on the second switching shaft 320, and a second positioning pin 420 is inserted into the second pin hole 324. The second switching component 300 can rotate relative to the switching cavity 113. It can be understood that the second switching component 300 can rotate relative to the switching cavity 113, slide relative to the switching cavity 113, or slide while rotating. The two ends of the switching cavity 113 are respectively provided with a third positioning part 1132 and a fourth positioning part (not shown). The third positioning part 1132 is located between the first water inlet channel 111 and the first operating part 313. When the second switching component 300 rotates relative to the switching cavity 113, the third positioning part 1132 cooperates with the first positioning pin 410 to limit the rotation of the second switching component 300. The fourth positioning part is located between the second water inlet channel 112 and the second operating part 323. The fourth positioning part cooperates with the second positioning pin 420 to limit the rotation of the second switching component 300.

[0070] Specifically, the third positioning part 1132 and the fourth positioning part can be bosses, annular ribs, etc., protruding from the inner wall of the switching cavity 113, and the platform of the positioning part for abutting the positioning pin is located on the rotation path of the positioning pin. When the user rotates the first operating part 313 or the second operating part 323, causing the first switching shaft 310 or the second switching shaft 320 to rotate in the switching cavity 113, the third positioning part 1132 and the fourth positioning part can stop the first positioning pin 410 and the second positioning pin 420 in a preset position, thereby limiting the rotation of the second switching assembly 300 and keeping the change in the hot and cold water flow area within a preset range.

[0071] refer to Figure 3 , Figure 4 and Figure 7In some embodiments of the present invention, a toothed surface 145 is provided on the inner peripheral wall of the water passage cavity 120, and a first convex shaft 146 is provided on the bottom wall. The first convex shaft 146 is inserted into the impeller 210, so that the impeller 210 is rotatably connected to the water passage cavity 120. When water flows into the water passage cavity 120 and impacts the impeller 210, the impeller 210 can rotate around the first convex shaft 146. The first switching assembly 200 also includes a first gear 230. A second gear 211 is provided on the side of the impeller 210 near the third water inlet 141. The first gear 230 meshes between the second gear 211 and the tooth surface 145. The first water baffle 220 is connected to the side of the first gear 230 near the water inlet channel. Thus, when the water flow impacts the impeller 210 and causes it to rotate, the second gear 211 rotates at the same time, driving the first gear 230 to rotate. Since the first gear 230 meshes with the tooth surface 145 of the inner peripheral wall of the water passage cavity 120, the first gear 230 can rotate around the first convex shaft 146 in the water passage cavity 120, thereby driving the first water baffle 220 to rotate to sequentially block the first water inlet 1111 and the second water inlet 1121.

[0072] refer to Figure 3 and Figure 4 In some embodiments of the present invention, a magnet 500 is also provided inside the water outlet device 1000. Specifically, there are two magnets 500, which are respectively provided at one end of the first water inlet channel 111 near the first water outlet 1111 and the other end of the second water inlet channel 112 near the second water outlet 1121. The first water baffle 220 is magnetic.

[0073] It is understandable that the magnetic part can be provided on the side of the first water-blocking component 220 facing the water inlet shell 110, or the entire side of the first water-blocking component 220 facing the water inlet shell 110 can be made of magnetic material, or the entire first water-blocking component 220 can be made of magnetic material. The magnet 500 and the two opposing sides of the first water-blocking component 220 have the same magnetism.

[0074] It is understandable that magnet 500 can be a magnet, which is assembled at the installation position, or it can be a part of the water outlet device that is made of magnetic material.

[0075] Specifically, when the impeller 210 rotates to the point where the first baffle 220 blocks one of the water inlet channels, the water flow into the water passage 120 decreases, reducing the impact force on the impeller 210 and thus lowering its rotational speed, thereby affecting the frequency of alternating hot and cold water output. By setting a magnet 500 and a magnetic first baffle 220, and ensuring that the magnetism on their opposing surfaces is the same, when the impeller 210 rotates and the first baffle 220 blocks one of the water inlet channels, the magnetism of the magnet 500 causes the first baffle 220, which has the same magnetism, to experience a repulsive force. When the magnetic field lines inside the first baffle 220 do not coincide with the magnetic field lines inside the magnet 500, the repulsive force of the magnet 500 on the first baffle 220 will generate a component force along the rotation direction of the first baffle 220, thereby driving the rotation of the first baffle 220 and preventing it from reducing its rotational speed due to the decrease in the impact water volume.

[0076] In some embodiments of the present invention, the water outlet channel includes a first water outlet channel 143 and a second water outlet channel 144. A fourth water outlet 142 is also provided in the water passage cavity. The first water outlet channel 143 is connected to the water passage cavity 120 through a third water outlet 141, and the second water outlet channel 144 is connected to the water passage cavity 120 through the fourth water outlet 142. The first switching component 200 also includes a second water baffle 240, which is disposed on the side of the second gear 211 near the water outlet channel. When the impeller 210 in the first switching component 200 rotates due to the impact of water flow, it can drive the second water baffle 240 to rotate together, thereby blocking the first water outlet channel 143 and the second water outlet channel 144 in sequence, so that the water flowing into the water passage cavity 120 can flow out from different water outlet channels.

[0077] Further reference Figure 3 , Figure 4 and Figure 7 In the direction of the rotation axis of the impeller 210, the third water inlet 141 is arranged opposite to the first water inlet 1111, that is, the projection of the third water inlet 141 along the axis of the impeller 210 overlaps with the first water inlet 1111. The fourth water inlet 142 and the second water inlet 1121 are also arranged opposite to each other.

[0078] Furthermore, a shaft hole is provided on one end of the second water baffle 240, which cooperates with the first convex shaft 146 through the shaft hole. The second water baffle 240 is rotatably connected to the water passage cavity 120. At the same time, a second convex shaft 241 is provided on the end of the second water baffle 240 away from the shaft hole. The second convex shaft 241 faces away from the water outlet channel, and the first gear 230 is rotatably mounted on the second convex shaft 241. Therefore, when the impeller 210 rotates, it simultaneously drives the first water-blocking component 220 and the second water-blocking component 240 to rotate. When the first water-blocking component 220 blocks the first water inlet 1111, the second water-blocking component 240 also blocks the third water inlet 141. At this time, the water flowing in through the second water inlet 1121 can only flow out through the fourth water inlet 142 and the second water outlet channel 144. When the first water-blocking component 220 blocks the second water inlet 1121, the second water-blocking component 240 also blocks the fourth water inlet 142. At this time, the water flowing in through the first water inlet 1111 can only flow out through the third water inlet 141 and the first water outlet channel 143. Therefore, during the alternating hot and cold water flow, cold and hot water can flow out through different water outlet channels, causing the specific impact points of the cold and hot water on the human skin to differ, thereby achieving another skin massage effect.

[0079] refer to Figure 3 , Figure 4 , Figure 5 and Figure 7 In some embodiments of the present invention, the housing 100 includes a water inlet housing 110 and a water distribution plate 140, wherein a first water inlet channel 111, a second water inlet channel 112, a switching chamber 113, a first water outlet 1111, and a second water outlet 1121 are all disposed on the water inlet housing 110. A cavity is disposed on the side of the water distribution plate 140 near the water inlet housing 110. The cavity is connected to the water inlet housing 110 to form a water passage cavity 120. The inner peripheral wall of the cavity constitutes the inner peripheral wall of the water passage cavity 120, and the bottom wall of the cavity constitutes the bottom wall of the water passage cavity 120. The third water outlet 141 and the fourth water outlet 142 are both located on the bottom wall of the cavity. The first water outlet channel 143 and the second water outlet channel 144 are located on the side of the water distribution plate 140 facing away from the water passage cavity 120. The housing 100 also includes a cover 160, which is located on the side of the water distribution plate 140 facing away from the water passage cavity 120. The cover 160 is provided with a first water outlet hole 161 and a second water outlet hole 162. The first water outlet channel 143 is connected to the outside water outlet through the first water outlet hole 161, and the second water outlet channel 144 is connected to the outside water outlet through the second water outlet hole 162. Thus, the hot and cold water of the water outlet device 1000 can flow out through different water outlet holes.

[0080] In some embodiments of the present invention, the housing 100 further includes a sealing disc 150, which is disposed between the water distribution disc 140 and the cover 160. The sealing disc 150 is also provided with a sealing ring 151, which is used to fit on the side of the water outlet facing the water outlet channel, so as to seal the connection between the first water outlet channel 143 and the first water outlet 161, and between the second water outlet channel 144 and the second water outlet 162.

[0081] Furthermore, the housing also includes a water outlet shell 130, which provides a receiving space for assembling the water distribution plate 140, the sealing plate 150, and the cover 160.

[0082] In other embodiments of the present invention, a shower head is also provided, including a water outlet device 1000. It is understood that the water outlet device 1000 can function as an overhead shower head, connected to a cold water source and a hot water source via water pipes. Cold and hot water enter the water outlet device 1000 through the water pipes. Once the user sets the water outlet mode, the alternating hot and cold water outlet mode can be used without manual operation.
