[0065] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0066] like Figure 1 and Figure 2 As shown, Figure 1 Shown is a perspective view of a spray boom according to an embodiment of the present invention. Figure 2 Shown is an exploded view of the spray rod of an embodiment of the present invention. The water outlet device of the embodiment of the present invention is applied to a smart toilet. The water outlet device 1 is connected to the spray rod body 2, and is used to achieve functions such as hip washing and feminine washing. It should be noted that the water outlet device 1 of the embodiment of the present invention is not limited to application in smart toilets, for example, it can also be applied to bathroom showers, car wash water guns, kitchen faucets or other suitable usage scenarios, and the embodiment of the present invention does not specifically limit this.

[0067] The water outlet device 1 of the embodiment of the present invention comprises a core 100, an upper cover 300 and a lower cover 400. The upper cover 300 can be configured as a cover. The core 100 is accommodated in the upper cover 300, and a part of the core 100 is enclosed in the cavity formed by the upper cover 300 and the lower cover 400 by snapping the lower cover 400 on the bottom of the upper cover 300. The other part of the core 100 is exposed in the cavity formed by the upper cover 300 and the lower cover 400, and is used to communicate with the flow channel of the spray rod body 2.

[0068] like Figures 3 to 5 As shown, Figure 3 Shown is a three-dimensional view of a water outlet device according to an embodiment of the present invention. Figure 4 It shows Figure 3 Sectional view along AA. Figure 5 The core 100 of the embodiment of the present invention comprises a mixing chamber 110, one or more first water inlets 120, one or more second water inlets 130 and a water outlet 140. The water outlet 140 is connected to the mixing chamber 110.

[0069] The core 100 further includes a first flow channel 150 and a second flow channel 160, wherein the first flow channel 150 is connected to the first water inlet 120, and the second flow channel 160 is connected to the second water inlet 130. The first flow channel 150 and the second flow channel 160 are independent of each other before being connected to the mixing chamber 110. The water flow can enter the mixing chamber 110 through the first flow channel 150 and the first water inlet 120 in sequence. The water flow can also enter the mixing chamber 110 through the second flow channel 160 and the second water inlet 130 in sequence. The water flow entering the mixing chamber 110 can finally be sprayed out through the water outlet 140.

[0070] like Figure 5 and Figure 6 As shown, Figure 6 The structure diagram of the core of the embodiment of the present invention from another perspective is shown. The mixing chamber 110 of the embodiment of the present invention defines a tangential direction, a radial direction and an axial direction. It should be explained that the tangential direction refers to the tangent direction along the arc surface, which is perpendicular to the direction of the normal; the radial direction refers to the direction along the diameter or radius of the arc surface; the axial direction refers to the axial direction along the arc surface.

[0071] Please continue reading Figure 5 and Figure 6 The first water inlet 120 is arranged in the mixing chamber 110 along the tangential direction. Since the flow direction of the first water inlet 120 is along the tangential direction of the mixing chamber 110, the water flow entering the mixing chamber 110 from the first water inlet 120 is in a stable vortex state. Due to the effect of centrifugal force, the water flow is finally ejected from the water outlet 140 and is a divergent particle water flow, that is, the first state water flow.

[0072] It should be noted that the first water inlet 120 should be arranged approximately along the tangential direction of the mixing chamber 110, rather than absolutely. It is sufficient that the water flow entering the mixing chamber 110 from the first water inlet 120 can generate a vortex.

[0073] The second water inlet 130 is disposed in the mixing chamber 110 along the radial direction. Since the flow direction of the second water inlet 130 is along the radial direction, the water flow entering the mixing chamber 110 from the second water inlet 130 does not generate vortexes, but is in a normal stable state. The water flow in the normal stable state is ejected from the water outlet 140 and is a columnar water flow, that is, the second state water flow.

[0074] It should be noted that the location of the second water inlet 130 should be understood as being roughly along the radial direction of the mixing chamber 110, rather than being absolute. For example, the flow direction of the second water inlet 130 is not directly opposite to the axis of the mixing chamber 110, but slightly deviates, and can generate a stable water flow, which should all be within the scope of protection of the present invention.

[0075] When water flows into the mixing chamber 110 from the first water inlet 120 and the second water inlet 130 at the same time, the water flows entering from the first water inlet 120 will form a vortex in the mixing chamber 110, and the water flows entering from the second water inlet 130 will form a normal stable state in the mixing chamber 110. The vortex will be disturbed by the water flow in the normal stable state and cannot form a fast and stable vortex, and finally a divergent water flow, i.e., a third state water flow, will be ejected from the water outlet 140. It can be understood that the third state water flow is an intermediate state water flow between the first state water flow and the second state water flow.

[0076] It is worth mentioning that when the ratio of the water flow entering from the first water inlet 120 to the water flow entering from the second water inlet 130 is larger, the vortex effect in the mixing chamber 110 is better, and the divergence effect of the water flow sprayed from the water outlet 140 is more obvious. On the contrary, the divergence effect is less obvious.

[0077] It can be seen from this that compared to the related art in which the water spray state is affected by the size of the spray rod and the water spray state is limited by the number of water outlets, the water outlet device of the embodiment of the present invention can steplessly adjust the water outlet form by adjusting the water inlet ratio of the first water inlet 120 and the second water inlet 130, thereby forming a variety of water spray forms, making the water outlet water spray forms richer and meeting the needs of different users for different water flow states.

[0078] It is understandable that the inner wall surface of the mixing chamber 110 can be an arc-shaped surface, for example, it can be a truncated cone, a cone or a cylinder. Of course, the inner wall surface of the mixing chamber 110 can also be in the shape of an ellipsoid. It should be noted that the shapes of the inner wall surface of the mixing chamber 110 listed above are only used as examples and should not be understood as limiting the shape of the inner wall surface of the mixing chamber 110. As long as the shape of the inner wall surface that satisfies the water flow entering the mixing chamber 110 from the first water inlet 120 can form a vortex in the mixing chamber 110, it should be within the scope of protection of the present invention.

[0079] In one embodiment, the center line of the water outlet 140 coincides with the axis of the mixing chamber 110 , but the present invention is not limited thereto.

[0080] like Figure 6 As shown, the number of the first water inlet 120 can be one, and the number of the second water inlet 130 can also be one, but it is not limited thereto. For example, the number of the first water inlet 120 can also be two, three, etc. The number of the second water inlet 130 can also be two, three, etc.

[0081] Please continue reading Figure 6 , the center line of the first water inlet 120 is substantially perpendicular to the center line of the second water inlet 130 , but this is not limited to the present invention.

[0082] like Figure 7 As shown, Figure 7The sectional view of the core of the embodiment of the present invention is shown. The aperture of the water outlet 140 is between 1 mm and 2 mm; or, the flow area of ​​the water outlet 140 is between 0.8 mm 2 ~3mm 2 Within this numerical range, the water output force of the water splash can be guaranteed, and the water output flow rate can be controlled within 0.5L / min to 1.5L / min, so that the water output device of the embodiment of the present invention can provide sufficient hot water in cold weather environments.

[0083] In addition, by limiting the minimum aperture of the water outlet 140 to 1 mm, the water outlet 140 is less likely to generate scale after long-term use, and is more durable.

[0084] Continue reading Figure 7 The cross-sectional area of ​​the mixing chamber 110 near the water outlet 140 is gradually reduced, thereby forming a shape roughly in the shape of a beer bottle or a cone. This design can make the water flow in the mixing chamber 110 easier to spray out from the water outlet 140.

[0085] like Figures 8 to 10 , Figure 8 Shown is a schematic structural diagram of a core body according to another embodiment of the present invention. Fig. 9 Shown is a cross-sectional view along the center line of the second water inlet of the core according to another embodiment of the present invention. Fig.10 The cross-sectional view along the axis of the mixing chamber of the core of another embodiment of the present invention is shown. The core 100 of this embodiment is different from the core 100 of the above embodiment in that the first water inlet 120 of the core 100 of this embodiment is arranged in the mixing chamber 110 along the tangential direction, and the second water inlet 130 is arranged in the mixing chamber 110 along the axial direction. The center line of the second water inlet 130 can be staggered with the center line of the water outlet 140.

[0086] Since the second water inlet 130 is disposed in the mixing chamber 110 along the axial direction, the water outflow force (columnar water flow) of the water flow in the second state is further guaranteed.

[0087] Please continue reading Figures 8 to 10 The number of the first water inlets 120 can be two, and the center lines of the two first water inlets 120 are parallel to each other. The advantage of such a design is that the effect of generating vortex can be better.

[0088] The number of the second water inlets 130 can be multiple, for example, two, three, four, etc.

[0089] In this embodiment, the cross-sectional area of ​​the mixing chamber 110 near the water outlet 140 can also be designed to gradually decrease, thereby forming a substantially beer bottle-shaped or conical shape. This design can make the water flow in the mixing chamber 110 easier to spray out from the water outlet 140.

[0090] like Fig.11 and Fig.12 As shown, Fig.11 Shown is a schematic structural diagram of a valve seat according to an embodiment of the present invention. Fig.12 The water outlet device of the embodiment of the present invention further comprises a water diverter valve 200 , which is configured to allow water flow to selectively enter the first water inlet 120 and / or the second water inlet 130 .

[0091] Specifically, the water supply pipe is connected to the water diverter valve 200, and after the water is diverted by the water diverter valve 200, the water flow supplied by the water supply pipe can selectively enter the first water inlet 120 and / or the second water inlet 130, and then flow out of the first state water flow, the second state water flow or the third state water flow from the water outlet 140.

[0092] In the related art, the smart toilet sprays water from the spray rod onto the buttocks of the human body. In order to avoid cold water irritating the user and bringing a bad experience, the current spray rod sprays warm water. The spray rod in the related art adopts a method of connecting different water outlets with different water outlets to realize the switching of the spray rod between functions such as buttock washing and women's washing. When one water outlet pipe and water outlet are passing water, the other water outlet pipe and water outlet are not used, causing the temperature of the water flow therein to gradually decrease and eventually turn into cold water. When the user switches from one water flow state to another, the cold water remaining in the unused water path needs to be drained before the warm water can be passed normally. During this process, the user needs to wait for a while, and the experience is poor.

[0093] The water outlet device of the embodiment of the present invention, through the setting of the water diverter valve 200, enables the water path of the first water inlet 120 and the water path of the second water inlet 130 to continuously flow warm water. When the water flow state needs to be switched, there is no need to wait, which improves the user experience. Specifically, the water flow in the water supply pipe connected to the water diverter valve 200 can be heated in advance. During the water diversion process of the water diverter valve 200, whether it is spraying the first state water flow, the second state water flow, or the third state water flow, the water flow in the flow channel in the water outlet device is supplied by the same water supply pipe, and is all warm water.

[0094] Please continue reading Fig.11 and Fig.12The water diverter valve 200 of the embodiment of the present invention comprises: a valve seat 210 and a moving member 220, wherein the valve seat 210 comprises a first water diverter hole 211 and a second water diverter hole 212, wherein the first water diverter hole 211 is connected to the first water inlet 120, and the second water diverter hole 212 is connected to the second water inlet 130. The moving member 220 is movably connected to the valve seat 210 and comprises a third water diverter hole 221, wherein the third water diverter hole 221 can be connected to a water supply pipe.

[0095] When the moving member 220 moves relative to the valve seat 210 , the third water diversion hole 221 may selectively correspond to the first water diversion hole 211 and / or the second water diversion hole 212 .

[0096] Specifically, if Figures 13 to 15 As shown, Fig.13 The diagram shows a schematic diagram of a water diversion valve in an embodiment of the present invention when only the first water diversion hole discharges water. Fig.14 The diagram shows a schematic diagram of a water diversion valve in an embodiment of the present invention when both the first water diversion hole and the second water diversion hole are discharging water. Fig.15 The diagram shows a schematic diagram of a water diversion valve according to an embodiment of the present invention when only the second water diversion hole discharges water.

[0097] like Fig.13 As shown, when the moving member 220 moves to the first position range relative to the valve seat 210, the third water diversion hole 221 only corresponds to the first water diversion hole 211, and the second water diversion hole 212 is blocked by the moving member 220. The water flow can pass through the third water diversion hole 221 and the first water diversion hole 211, and flow into the first water inlet 120, and finally spray out the first state water flow.

[0098] When the moving member 220 moves to the second position range relative to the valve seat 210, the first water diversion hole 211 and the second water diversion hole 212 both correspond to the third water diversion hole 221, so that the water flow can pass through the first water diversion hole 211 and the second water diversion hole 212 from the third water diversion hole 221, and flow into the first water inlet 120 and the second water inlet 130 respectively, and finally spray out the third state water flow.

[0099] When the moving member 220 moves to the third position range relative to the valve seat 210, the third water diversion hole 221 only corresponds to the second water diversion hole 212, and the first water diversion hole 211 is blocked by the moving member 220. The water flow can pass through the third water diversion hole 221 and the second water diversion hole 212, and flow into the second water inlet 130, and finally spray out the second state water flow.

[0100] It is understandable that the correspondence between the two water diversion holes can be that the two water diversion holes are completely aligned, in which case the water flow rate passing through is the largest, or that the two water diversion holes are partially aligned, in which case the water flow rate passing through is reduced.

[0101] Please continue reading Fig.11 and Fig.12 The valve seat 210 and the moving member 220 are both disc-shaped and rotatably overlapped with each other. The first water diversion hole 211, the second water diversion hole 212 and the third water diversion hole 221 are all waist-shaped holes. The first water diversion hole 211 and the second water diversion hole 212 extend along the circumferential direction of the valve seat 210 and are arranged at intervals. The third water diversion hole 221 extends along the circumferential direction of the moving member 220.

[0102] In this embodiment, since the first water diversion hole 211, the second water diversion hole 212 and the third water diversion hole 221 are all waist-shaped holes, and the first water diversion hole 211 and the second water diversion hole 212 extend along the circumferential direction of the valve seat 210, and the third water diversion hole 221 extends along the circumferential direction of the moving part 220, when the moving part 220 rotates relative to the valve seat 210, the water flow rate passing through the first water diversion hole 211 and the second water diversion hole 212 can change slowly and evenly, so that the outlet water flow can also change steplessly, slowly and evenly, and the water flow state is richer.

[0103] Of course, it is understandable that the movable member 220 can also move back and forth linearly relative to the valve seat 210; or, the waist-shaped hole can be changed into a plurality of small holes with different apertures, and the flow rate can be adjusted by rotating the movable member 220 to achieve the effect of water division; or, by controlling the opening size of the two valves, thereby controlling the water inlet flow rate of the two routes, the water division effect can also be achieved. Specifically, the opening area of ​​the valve can be controlled separately by two motors, thereby realizing the control of the flow ratio and realizing precise control of the water flow rate of the two routes.

[0104] like Figures 16 to 18 As shown, Fig.16 Shown is a schematic diagram of the water outlet device of an embodiment of the present invention when water flows out in a first state. Fig.17 Shown is a schematic diagram of the water outlet device of an embodiment of the present invention discharging water in the second state. Fig.18 Shown is a schematic diagram of the water outlet device of the embodiment of the present invention when it discharges water in the third state.

[0105] like Fig.16 As shown, the water flows into the mixing chamber 110 only from the first water inlet 120 , and the water outlet 140 finally sprays out a divergent particle water flow, that is, a first state water flow.

[0106] like Fig.17 As shown, the water flows into the mixing chamber 110 only from the second water inlet 130 , and the water outlet 140 finally sprays out a columnar water flow, that is, the water flow in the second state.

[0107] like Fig.18 As shown, water flows into the mixing chamber 110 from the first water inlet 120 and the second water inlet 130 at the same time, and the water outlet 140 finally sprays out the third state water flow.

[0108] Another aspect of the present invention further provides a smart toilet, comprising a water outlet device of any of the above embodiments. Since the water outlet device of any of the above embodiments is included, the smart toilet of this embodiment has all the advantages and beneficial effects of any of the above embodiments, which will not be described in detail here.

[0109] In summary, the advantages and beneficial effects of the water outlet device and the smart toilet according to the embodiments of the present invention are:

[0110] Compared with the method of connecting different water outlet pipes to different water outlets adopted in the related art, the water outlet device of the embodiment of the present invention adopts the technical means of setting the first water inlet 120 in the mixing chamber 110 along the tangential direction and the second water inlet 130 in the mixing chamber 110 along the radial direction, so that the water flow state sprayed out of the water outlet 140 can be adjusted according to the water intake ratio of the first water inlet 120 and the second water inlet 130, so as to achieve the effect of different water in the same hole. It has the advantages of simple structure and richer water flow state, and can meet the different water flow state requirements of different users.

[0111] In addition, when switching between different water flow states, the water outlet device of the embodiment of the present invention can continuously spray warm water without waiting, which significantly improves the user experience.
