[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] refer to Figure 1In some specific embodiments of the present invention, a water outlet device 1000 is provided, which can automatically realize the alternating discharge of hot and cold water, and can be applied to scenes such as showering in the bathroom or using water in the kitchen. For example, the water outlet device 1000 can be used as a component of water outlet devices such as a hand-held shower, a top shower, a spray gun, and a faucet. Cold water and hot water enter the water outlet device 1000 through different water inlet pipes, respectively, and can realize automatic alternating discharge of hot and cold water. Among them, automatic alternating discharge of hot and cold water means that the user does not need to constantly manually switch the cold water inlet and the hot water inlet, that is, the alternating discharge of cold and hot water in circulation can be automatically realized, thereby achieving the effect of stimulating the human body.

[0021] refer to Figure 1-Figure 4 The water outlet device 1000 of the embodiment of the present invention 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 which are connected in sequence, and 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 chamber 120 through a first water passage 1111, and the second water inlet channel 112 is connected to the water chamber 120 through a second water passage 1121, and the water passage chamber 120 is connected to the water outlet channel through a third water passage 141. Thus, hot and cold water can pass through the first water inlet channel 111 and the second water inlet channel 112 respectively, and enter the water passage chamber 120 after flowing through the first water passage 1111 and the second water passage 1121 respectively, and then flow out through the water outlet channel through the third water passage 141 for showering. The first switching component 200 is arranged in the water flow chamber 120, including an impeller 210 and a first water blocking member 220. When cold water and / or hot water enters the water flow chamber 120, it will impact the impeller 210 and make it rotate, and the impeller 210 will drive the first water blocking member 220 to rotate. During the rotation of the first water blocking member 220, the first water blocking member 220 is used to cover or open the first water outlet 1111 and the second water outlet 1121.

[0022] Among them, the first water inlet channel 111 can be a cold water channel, and the second water inlet channel 112 can be a hot water channel, or the first water inlet channel 111 can be a hot water channel, and the second water inlet channel 112 can be a cold water channel. The following takes the first water inlet channel 111 as a cold water channel and the second water inlet channel 112 as a hot water channel as an example for explanation: when the first water retaining member 220 blocks the first water outlet 1111, the cold water inlet is closed, the hot water inlet is opened, and the hot water flows out through the second water inlet channel 112, the second water outlet 1121, the water chamber 120, the third water outlet 141 and the water outlet in sequence; when the first water retaining member 220 rotates to block the second water outlet 1121, the hot water inlet is closed, the cold water inlet is opened, and the cold water flows out from the water outlet. It can be understood that there is also a situation where the first water retaining member 220 opens the first water outlet 1111 and the second water outlet 1121 at the same time.

[0023] Thus, the impeller 210 can be driven to rotate by the water flow, thereby causing the first water blocking member 220 to automatically circulate and rotate, repeatedly blocking and opening the first water outlet 1111 and the second water outlet 1121 in turn, 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.

[0024] refer to Figure 4 In some embodiments of the present invention, the first water retaining member 220 is a fan-shaped structure, wherein the fan-shaped structure is divergent along the circumferential direction of the impeller 210 with the rotation axis of the impeller 210 as the center, and the angle of the fan-shaped structure can be 180°. Thus, the first water retaining member 220 can always keep one of the first water outlet 1111 and the second water outlet 1121 open during the rotation process, while blocking the other, so as to always keep cold water or hot water outflow, avoid the mixing of cold and hot water in the water passage chamber 120 or block the cold and hot water at the same time so that the water cannot be discharged. In this case, the user can enjoy the stimulation of alternating extremely cold and extremely hot water outflow.

[0025] In some embodiments of the present invention, the first water retaining member 220 is a fan-shaped structure, wherein the fan shape is divergent along the circumferential direction of the impeller 210 with the rotation axis of the impeller 210 as the center, and the angle of the fan shape is less than 180°. Since alternating showers with extremely cold and hot water will stimulate the rapid expansion and contraction of human blood vessels, people with special physical conditions, such as the elderly, children, or patients, may not adapt to such extreme cold and hot changes, and may even have the opposite stimulation effect. Therefore, the angle of the first water retaining member 220 is designed to be less than 180°. When the first water retaining member 220 is rotating, in addition to blocking the first water outlet 1111 or blocking the second water outlet 1121, there is also a position where the first water outlet 1111 and the second water outlet 1121 are opened at the same time. At this time, hot and cold water can enter the water chamber 120 at the same time to mix, so as to form mixed warm water with a temperature higher than that of cold water and lower than that of hot water. Reference Fig.13 Taking the fan angle of the first water retaining member 220 as 72° as an example, when the water outlet device 1000 is turned on, the water flow impacts the impeller 210 to drive the first water retaining member 220 to rotate. At this time, the water at different temperatures is in the order of cold water: warm water: hot water = 72°: 216°: 72° = 1:3:1 in terms of water outlet time, that is, at a certain water outlet time ratio, a circulating cold-warm-hot water outlet effect is presented. Therefore, when people with special physiques enjoy the alternating stimulation of cold and hot water, a warm water transition stage is added, thereby avoiding the drastic water temperature changes between extreme cold and extreme heat causing human discomfort.

[0026] It can be understood that the fan shape of the first water baffle 220 can be designed at a variety of different angles and can be changed according to the different physiques or needs of users. For example, when the user wants to enjoy extreme cold or hot stimulation for a longer time, the fan angle can be increased to reduce the warm water outlet time. Conversely, the fan angle can be reduced to increase the warm water outlet time and reduce the degree of water outlet stimulation.

[0027] refer to Figure 3 and Figure 4 In some embodiments of the present invention, the housing 100 further includes a switching chamber 113, the extension direction of the switching chamber 113 is perpendicular to the axis of the water inlet channel, and the switching chamber 113 is connected to the first water inlet channel 111 and the second water inlet channel 112. The water outlet device 1000 also includes a second switching component 300, which is disposed in the switching chamber 113 and can slide relative to the switching chamber 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 chamber 120, and the second through hole 321 is used to connect the second water inlet channel 112 and the water passage chamber 120. When the second switching component 300 slides in the switching chamber 113, the connected water passing area between the first through hole 311 and the first water inlet channel 111 and the connected water passing area between the second through hole 321 and the second water inlet channel 112 can be changed, thereby changing the water flow rate of cold and hot water during alternating showers.

[0028] 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. The user selects different functions by controlling the switch, and the central control component controls the motor to drive the second switching component 300 to slide.

[0029] The present embodiment is further described below. The second switching assembly 300 can slide to different positions relative to the switching cavity 113: When the second switching assembly 300 slides to the first position, Figure 8(The dotted line with an arrow in the figure is the direction of water flow), the connecting water flow area between the first through hole 311 and the first water inlet channel 111 is the largest, and the connecting area between the second through hole 321 and the second water inlet channel 112 is 0. At this time, the water outlet device 1000 can only pass and flow out cold water. At this time, the first switching component 200 rotates in the water flow impact in the water flow chamber 120. When the first water blocking member 220 blocks the second water outlet 1121, it does not affect the cold water outlet. At this time, the water outlet device 1000 discharges cold water. When it rotates to block the first water outlet 1111, no cold water or hot water passes through the water outlet chamber 120. At this time, the water outlet device 1000 does not discharge water, and the impeller 210 continues to rotate until the first water blocking member 220 opens the first water outlet 1111 again, and the water outlet device 1000 outputs cold water again. As a result, cold water is discharged intermittently in pulses, which can achieve a massage effect on the human body.

[0030] When the second switching assembly 300 slides to the second position, Fig. 9 (The dotted line with an arrow in the figure is the direction of water flow). At this time, the hot water connection area is the largest, and the cold water connection area is 0, just like the water discharge process in the first position mentioned above, realizing intermittent pulse water discharge of hot water with a massage effect.

[0031] When the second switching assembly 300 slides to the third position, Fig.10 (The dotted line with an arrow in the figure is the direction of water flow). At this time, the connected water flow area between the first through hole 311 and the first water inlet channel 111 and the connected area between the second through hole 321 and the second water inlet channel 112 are not 0. At this time, both cold water and hot water can enter the water flow chamber 120. When the angle of the fan-shaped first water retaining member 220 is 180°, during the rotation of the first water retaining member 220, the first water inlet channel 111 and the second water inlet channel 112 always keep one of them connected and the other closed, so that cold-hot water can be discharged alternately. When the angle of the fan-shaped first water retaining member 220 is less than 180° (such as 72°), cold-warm-hot water is discharged alternately.

[0032] Furthermore, when the second switching component 300 is in the third position, the user can also push the second switching component 300 to slide according to the needs to increase the water flow area between the first through hole 311 and the first water inlet channel 111, and reduce the water flow area between the second through hole 321 and the second water inlet channel 112, thereby increasing the cold water flow rate during the alternating water discharge process while reducing the hot water flow rate, and so on. In the process of cold-hot or cold-warm-hot alternating water discharge to stimulate the human body, a pulse massage effect with a large cold water flow rate and a small hot water flow rate is provided to the user. It is understandable that the user can also reversely adjust to a pulse massage effect with a small cold water flow rate and a large hot water flow rate.

[0033] refer to Figure 3 , Figure 4In some embodiments of the present invention, the housing 100 further includes a switching chamber 113, the extension direction of the switching chamber 113 is perpendicular to the axis of the water inlet channel, and the switching chamber 113 is connected to 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 chamber 113 and can rotate relative to the switching chamber around the axis of the switching chamber 113. Among them, 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 flow chamber 120, and the second through hole 321 is used to connect the second water inlet channel 112 and the water flow chamber 120. Specifically, when the second switching component 300 rotates in the switching chamber 113, it can change the connected water flow area between the first through hole 311 and the first water inlet channel 111, and / or the connected 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 flow chamber 120.

[0034] Specifically, the second switching component 300 can be manually operated by the user to enable it to rotate relative to the switching cavity 113, or it can be driven by a motor. The user selects different functions by controlling the switch, and the central control component controls the motor to drive the second switching component 300 to rotate.

[0035] For example, the user can rotate the second switching assembly 300 to simultaneously reduce the connecting water flow area between the first through hole 311 and the first water inlet channel 111, and the connecting water flow area between the second through hole 321 and the second water inlet channel 112, thereby reducing the flow of cold and hot water entering the water flow chamber 120, thereby adjusting the alternating water flow rate.

[0036] 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, the first through hole 311 is provided on the first switching shaft 310, and the 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 close to the second switching shaft 320, and a second connecting portion 322 is provided on one end of the second switching shaft 320 close to the first switching shaft 310, and 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 pivoting connection means that the first switching shaft 310 and the second switching shaft 320 can both rotate independently around the axis of the switching chamber 113, that is, the first switching shaft 310 or the second switching shaft 320 can be rotated alone.

[0037] Specifically, one of the first connection portion 312 and the second connection portion 322 may be a universal ball head, and the other may be a groove adapted to the universal ball head. The first connection portion 312 and the second connection portion 322 may 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 independently rotate around the axis of the switching chamber 113.

[0038] Therefore, the user can choose to rotate the first switching shaft 310 or the second switching shaft 320 according to needs, so as to change the flow ratio of cold water and hot water entering the water passage chamber 120.

[0039] Next, the present embodiment is described by taking an example, with the connected water flow area between the second through hole 321 and the second water inlet channel 112 unchanged (for example, the hot water flow area is kept at the maximum): refer to Fig.11 , rotate the first switching shaft 310 so that the first through hole 311 and the first water inlet channel 111 completely overlap, at which time the connected water flow area between the two is the largest, and the amount of cold water and hot water entering the water flow chamber 120 is the largest. When the fan angle of the first water retaining member 220 is 180°, the alternating cold water and hot water reach the maximum flow rate; when the fan angle of the first water retaining member 220 is less than 180° (such as 72°), the alternating cold water, warm water and hot water reach the maximum flow rate.

[0040] refer to Fig.12 , continue to rotate the first switching shaft 310 so that the first through hole 311 and the first water inlet channel 111 only partially overlap. At this time, the water flow area between the first through hole 311 and the first water inlet channel 111 is reduced. At this time, the flow rate of cold water entering the water chamber 120 is less than the flow rate of hot water. When the fan angle of the first water retaining member 220 is 180°, during the alternating flow of cold and hot water, the flow rate of cold water is less than the flow rate of hot water, thereby presenting a pulse massage effect. When the fan angle of the first water retaining member 220 is less than 180° (such as 72°), the water flows out alternately in cold-warm-hot. At this time, since the flow rate of cold water is less than the flow rate of hot water, the alternating flow process not only presents a pulse massage effect, but also the temperature of the warm water at this time is higher than Fig.11 The warm water temperature shown is when the cold water flow rate entering the water passage chamber 120 is maximum.

[0041] Therefore, the user can adjust the flow rate of cold water and hot water entering the water chamber 120 by rotating the first switching shaft 310 or the second switching shaft 320, so that the cold and hot water are alternately discharged to achieve a pulse massage effect, or the pulse massage effect can be achieved while adjusting the water temperature of the warm water during the cold-warm-hot alternating water discharge process, so as to better meet the user's personalized needs.

[0042] refer to Figure 3 and Figure 4 In some embodiments of the present invention, a first operating portion 313 is provided on one end of the first switching shaft 310 away from the second switching shaft 320, and a second operating portion 323 is provided on one end of the second switching shaft 320 away from the first switching shaft 310. The first operating portion 313 and the second operating portion 323 may be a hand wheel, a knob, etc. The user may push and pull the first operating portion 313 or the second operating portion 323 so that the second switching assembly 300 may slide in the switching cavity 113. The user may also rotate the first operating portion 313 and the second operating portion 323 so that the first switching shaft 310 and / or the second switching shaft 320 rotate in the switching cavity 113.

[0043] 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, can rotate relative to the switching cavity 113, or can rotate while sliding. A first positioning portion 1131 and a second positioning portion (not shown) are respectively provided at both ends of the switching chamber 113. The first positioning portion 1131 is provided between the first water inlet channel 111 and the first operating portion 313. When the second switching component 300 slides relative to the switching chamber 113, the first positioning portion 1131 cooperates with the first positioning pin 410 to limit the sliding of the second switching component 300. The second positioning portion is provided between the second water inlet channel 112 and the second operating portion 323. The second positioning portion cooperates with the second positioning pin 420 to limit the sliding of the second switching component 300.

[0044] Specifically, the first positioning portion 1131 and the second positioning portion can be a boss, annular rib, etc. protruding from the inner wall of the switching cavity 113, and the direction of the table surface of the positioning portion for abutting against the positioning pin is parallel to the sliding direction of the second switching component 300. When the user pushes and pulls the first operating portion 313 or the second operating portion 323 to make the second switching component 300 slide in the switching cavity 113, the first positioning portion 1131 and the second positioning portion can stop the first positioning pin 410 and the second positioning pin 420 at the preset position, thereby limiting the sliding of the second switching component 300, so that the change of the cold and hot water water flow area is always kept within the preset range.

[0045] refer to Figure 3 , Figure 4 and Figure 5In some embodiments of the present invention, the first switching shaft 310 is provided with a first pin hole 314 , and the first positioning pin 410 is inserted into the first pin hole 314 ; the second switching shaft 320 is provided with a second pin hole 324 , and the second positioning pin 420 is inserted into the second pin hole 324 . The second switching component 300 can rotate relative to the switching chamber 113. It can be understood that the second switching component 300 can rotate relative to the switching chamber 113, can slide relative to the switching chamber 113, or can slide while rotating. The third positioning portion 1132 and the fourth positioning portion (not shown) are respectively provided at both ends of the switching chamber 113. The third positioning portion 1132 is provided between the first water inlet channel 111 and the first operating portion 313. When the second switching component 300 rotates relative to the switching chamber 113, the third positioning portion 1132 cooperates with the first positioning pin 410 to limit the rotation of the second switching component 300. The fourth positioning portion is provided between the second water inlet channel 112 and the second operating portion 323. The fourth positioning portion cooperates with the second positioning pin 420 to limit the rotation of the second switching component 300.

[0046] Specifically, the third positioning portion 1132 and the fourth positioning portion can be a boss, annular rib, etc. protruding from the inner wall of the switching chamber 113, and the table surface of the positioning portion used to abut the positioning pin is located on the rotation path of the positioning pin. When the user rotates the first operating portion 313 or the second operating portion 323 to rotate the first switching shaft 310 or the second switching shaft 320 in the switching chamber 113, the third positioning portion 1132 and the fourth positioning portion can stop the first positioning pin 410 and the second positioning pin 420 at the preset position, thereby limiting the rotation of the second switching assembly 300, so that the change of the cold and hot water water flow area is always kept within the preset range.

[0047] refer to Figure 3 , Figure 4 and Figure 7In some embodiments of the present invention, a tooth surface 145 is provided on the inner circumferential wall of the water passage chamber 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 chamber 120. When water flows into the water passage chamber 120 to impact the impeller 210, the impeller 210 can rotate around the first convex shaft 146. The first switching component 200 also includes a first gear 230, and a second gear 211 is provided on the side of the impeller 210 close to the third water outlet 141, and the first gear 230 is meshed between the second gear 211 and the tooth surface 145, wherein the first water retaining member 220 is connected to a side of the first gear 230 close to the water inlet channel, thereby, when the water flow impacts the impeller 210 to rotate, the second gear 211 rotates at the same time, driving the first gear 230 to rotate, and since the first gear 230 is meshed with the tooth surface 145 of the inner wall of the water passage chamber 120 at the same time, the first gear 230 can rotate around the first convex shaft 146 in the water passage chamber 120, thereby driving the first water retaining member 220 to rotate to sequentially cover the first water outlet 1111 and the second water outlet 1121.

[0048] refer to Figure 3 and Figure 4 In some embodiments of the present invention, a magnet 500 is further provided in 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 close to the first water outlet 1111 and one end of the second water inlet channel 112 close to the second water outlet 1121. The first water retaining member 220 is magnetic.

[0049] It is understandable that the magnetic part may be provided on the surface of the first water retaining member 220 facing the water inlet shell 110, or the entire surface of the first water retaining member 220 facing the water inlet shell 110 may be made of magnetic material, or the entire first water retaining member 220 may be made of magnetic material. The magnetism of the magnet 500 and the two opposite surfaces of the first water retaining member 220 are the same.

[0050] It is understandable that the magnet 500 can be a magnet that is assembled at the installation position, or it can be a part of the water outlet device that is made of magnetic material.

[0051] Specifically, when the impeller 210 rotates to the point where the first water retaining member 220 blocks one of the water inlet channels, the water flow rate entering the water passage chamber 120 is reduced, and the impact force on the impeller 210 is reduced, so that the rotation speed of the impeller 210 is reduced, thereby affecting the frequency of alternating hot and cold water discharge. By providing a magnet 500 and a first water retaining member 220 having magnetism, and making the magnetism on two opposite surfaces of the two identical, when the impeller 210 rotates to cause the first water retaining member 220 to block one of the water inlet channels, due to the magnetism of the magnet 500, the first water retaining member 220 having the same magnetism is subjected to a repulsive force, and when the magnetic flux lines inside the first water retaining member 220 do not overlap with the magnetic flux lines inside the magnet 500, the repulsive force of the magnet 500 on the first water retaining member 220 will generate a component force along the rotation direction of the first water retaining member 220, thereby promoting the rotation of the first water retaining member 220, and preventing it from reducing its rotation speed due to the reduction of the impact water volume.

[0052] 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, and a fourth water outlet 142 is further provided in the water passage chamber. The first water outlet channel 143 is connected to the water passage chamber 120 via the third water outlet 141, and the second water outlet channel 144 is connected to the water passage chamber 120 via the fourth water outlet 142. The first switching component 200 also includes a second water retaining member 240, and the second water retaining member 240 is provided on a side of the second gear 211 close to the water outlet channel. When the impeller 210 in the first switching component 200 is rotated by the impact of the water flow, the second water retaining member 240 can be driven to rotate together, so as to sequentially block the first water outlet channel 143 and the second water outlet channel 144, so that the water entering the water passage chamber 120 can flow out from different water outlet channels. For further reference, Figure 3 , Figure 4 and Figure 7 In the direction of the rotation axis of the impeller 210, the third water outlet 141 is arranged opposite to the first water outlet 1111, that is, the projection of the third water outlet 141 along the axis of the impeller 210 overlaps with the first water outlet 1111, and the fourth water outlet 142 and the second water outlet 1121 are also arranged opposite to each other.

[0053] Furthermore, an axial hole is provided on one end of the second water retaining member 240, and the second water retaining member 240 is rotatably connected to the water passage chamber 120 through the axial hole and the first convex shaft 146. At the same time, a second convex shaft 241 is provided on the end of the second water retaining member 240 away from the axial hole, and the second convex shaft 241 faces away from the water outlet channel, and the first gear 230 is rotatably penetrated on the second convex shaft 241. Thus, when the impeller 210 rotates, the first water retaining member 220 and the second water retaining member 240 can be driven to rotate at the same time. When the first water retaining member 220 blocks the first water outlet 1111, the second water retaining member 240 also blocks the third water outlet 141 at the same time. At this time, the water flow entering through the second water outlet 1121 can only flow out through the fourth water outlet 142 and the second water outlet channel 144. When the first water retaining member 220 blocks the second water outlet 1121, the second water retaining member 240 also blocks the fourth water outlet 142 at the same time. At this time, the water flow entering through the first water outlet 1111 can only flow out through the third water outlet 141 and the first water outlet channel 143. Therefore, in the process of alternating cold and hot water discharge, cold water and hot water can flow out through different water outlet channels, so that the specific impact positions of cold water and hot water on human skin are different, thereby achieving another skin massage effect.

[0055] In some embodiments of the present invention, the shell 100 also includes a sealing disk 150, which is arranged between the water diversion disk 140 and the surface cover 160. A sealing ring 151 is also provided on the sealing disk 150. The sealing ring 151 is used to be sleeved on the side of the water outlet hole facing the water outlet channel to ensure a sealed connection between the first water outlet channel 143 and the first water outlet hole 161, and between the second water outlet channel 144 and the second water outlet hole 162.
