The hygiene functions of smart toilets can include at least the following: First, they can clean the anus, effectively reducing anal diseases in users; second, they can clean the female genital area, reducing bacterial infections and significantly lowering the incidence of gynecological and anorectal diseases; furthermore, the water flow of a smart toilet can provide a massage function, with varying water intensities repeatedly acting on the cleansing area, promoting blood circulation and preventing related diseases, especially beneficial for those suffering from constipation, as it promotes bowel movements.

[0003] Therefore, the needs of different users for smart toilets often vary. However, current smart toilets tend to have limited functionality and cannot meet the diverse needs of users. Therefore, the market urgently needs a smart toilet that can offer multiple cleaning functions. Summary of the Invention

[0004] This invention provides a switchable water spray gun assembly and a smart toilet that can meet the needs of various users and control the switching of multiple water types.

[0005] A switchable water spray gun assembly includes:

[0006] The spray gun is equipped with a water delivery channel;

[0007] A water pattern switching device is installed at the water outlet end of the spray gun, and the water pattern switching device includes:

[0008] A base is fixedly installed at the water outlet end of the spray gun. The base has a water inlet channel for water to pass through. The water inlet channel is connected to the water delivery channel. A water outlet is formed on the top end face of the water inlet channel. The base also has a shaft hole on one side of the water outlet.

[0009] A rotating shaft is rotatably inserted into the shaft hole, and the free end of the rotating shaft passes through the base;

[0010] A turntable is connected to the free end of the rotating shaft. The rotating shaft drives the turntable to rotate. The turntable is equipped with multiple water outlet valves for spraying different water patterns. The rotation of the turntable causes the different water outlet valves to be aligned with the water inlet and connected to the water inlet channel.

[0011] In one embodiment, the spray gun includes a gun body, a spray nozzle is provided on the side wall of the gun body, the outlet of the water valve faces the side wall of the gun body, and the turntable rotates to align the outlet of one of the water valves with the spray nozzle.

[0012] In one embodiment, the bottom surface of the turntable and the top surface of the base are kept in a surface seal.

[0013] In one embodiment, the turntable has multiple through holes corresponding to multiple water outlet valves, and each water outlet valve is connected to a through hole. By rotating the turntable, the through holes corresponding to different water outlet valves are adjusted to be aligned with the water inlet.

[0014] In one embodiment, the turntable forms a blocking area between two adjacent through holes, and the central angle corresponding to the water outlet is larger than the central angle corresponding to the blocking area.

[0015] In one embodiment, the water type switching device further includes a front cover, which is fixedly engaged with the base, and the front cover and the base form a receiving cavity, in which the turntable is received.

[0016] In one embodiment, the device further includes an angle detection device and a controller. The angle detection device is used to measure the rotation angle information of the shaft. The angle detection device is electrically connected to the controller, and the controller controls the rotation angle of the shaft according to the rotation angle information.

[0017] In one embodiment, the base includes a rear shell and a fixed plate, the rotating shaft passes through the fixed plate, and the water inlet channel includes a first channel provided on the rear shell and a second channel provided on the fixed plate. The first channel is connected to the water supply pipe, and the second channel forms the water outlet on the surface of the fixed plate.

[0018] The rear shell is provided with a water-containing cavity, and the fixed plate is housed in the water-containing cavity. The first channel and the second channel are respectively connected to the water-containing cavity. The cleaning water enters the water-containing cavity through the first channel and enters the second channel, and flows out from the water outlet.

[0019] In one embodiment, the spray nozzle is elongated, and the extension direction of the spray nozzle is the same as the rotation direction of the water pattern switching device.

[0020] A smart toilet includes:

[0021] Ceramic body;

[0022] A toilet seat, including the switchable water spray gun assembly, is mounted on top of a ceramic body.

[0023] As can be seen from the above technical solution, the present invention has at least the following advantages and positive effects:

[0024] The aforementioned switchable water spray gun assembly has a water pattern switching device at the water outlet end. The water pattern switching device includes a base, a rotating shaft, and a turntable. The turntable has multiple water outlet valves with different water patterns. The rotating shaft drives the turntable to rotate, aligning the water outlet valves for different water patterns, thus allowing for adjustment and switching between different spray patterns. Users can choose to switch between different spray patterns to suit their specific needs. Spray patterns can include linear, flower-shaped, polygonal, and shower-like patterns, etc.

[0025] Furthermore, the aforementioned multiple water outlet valves can be switched and installed through a single turntable. Compared to traditional spray guns with multiple water patterns, the entire water pattern switching device has a simple structure and a small size, greatly reducing the volume of the switchable water pattern spray gun assembly.

[0026] Furthermore, the turntable of the water pattern switching device rotates at different angles to correspond to different outlet valves. The angle of the turntable is relatively easy to control and the control is relatively convenient, which can improve the convenience and accuracy of water pattern control of the water pattern switching device.

It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0059] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0060] A smart toilet includes a toilet seat and a ceramic body, with the toilet seat mounted on top of the ceramic body. The ceramic body has a cavity, and the toilet seat is positioned above the cavity. The toilet seat is equipped with a switchable water-type spray gun assembly. The switchable water-type spray gun assembly is positioned above the cavity, and its spray nozzle extends and retracts downwards towards the center of the cavity.

[0061] The aforementioned toilet seat includes a seat body and a switchable water spray gun assembly. The seat body can be made of plastic. The seat body is mounted on top of a ceramic body, and the toilet seat can be fixed to the ceramic body with bolts.

[0062] The switchable water spray gun assembly is fixed inside the cover. For example, the switchable water spray gun assembly can be fixed inside the cover by screws through a threaded connection.

[0063] Traditional spray guns can also have multiple water pattern switching functions, which is often achieved by setting up multiple independent water pipes with different water patterns, and these multiple water pipes are connected in parallel. In addition, each water pipe is equipped with a valve, and by controlling the opening and closing of the valves, the flow of water in that water channel is controlled, thereby controlling the water pattern of the spray gun.

[0064] Please see Figure 1 and Figure 2 The switchable water spray gun assembly of this embodiment includes a mounting bracket 10, a spray gun 20, and a water type switching device 30. The mounting bracket 10 is fixedly mounted on the cover. The spray gun 20 is slidably mounted on the mounting bracket 10. The spray gun 20 can be retractably slid into the ceramic body, and sprays cleaning water of different types through the water type switching device 30 to meet the user's cleaning needs.

[0065] Mounting bracket 10 can be made of plastic. Mounting bracket 10 can be fixed to the cover body with screws. Mounting bracket 10 is used to provide support for the installation of spray gun 20.

[0066] Furthermore, the switchable water spray gun assembly of this embodiment also includes a power unit and a transmission structure. The mounting bracket 10 is provided with multiple mounting positions for fixing and mounting the spray gun 20, power unit, transmission device, pipeline cables, etc.

[0067] The mounting bracket 10 is provided with a motion guide rail 12, on which the spray gun 20 is slidably mounted. The motion guide rail 12 provides guidance for the extension and retraction of the spray gun 20. Specifically, in this embodiment, the spray gun 20 is roughly barrel-shaped and is telescopically mounted on the mounting bracket 10. The spray gun 20 is arc-shaped. Therefore, during the extension and retraction of the spray gun 20, it moves along an arc-shaped trajectory. Thus, since the movement trajectory of the spray gun 20 is arc-shaped, the shape of the motion guide rail 12 is also arc-shaped and is mounted on the mounting bracket 10. Furthermore, the spray gun 20 is mounted on the motion guide rail 12 via a snap-fit ​​connection.

[0068] In other embodiments, the spray gun 20 may also be linear, and thus it may extend and retract along a linear track. The specific shape of the spray gun 20 is not limited here, as long as it can achieve the extension and retraction motion.

[0069] Please see Figure 3 Specifically, in this embodiment, the power unit is used to provide power. The power unit includes a first motor 41 for driving the extension and retraction of the spray gun 20 and a second motor 42 for driving the water pattern switching device 30 to switch water patterns. It is understood that the power unit can also be other driving devices such as a rotary motor, a telescopic motor, or a cylinder.

[0070] The transmission device may include meshing transmission gears and a transmission rack. The transmission gears may be connected to the first motor 41, which drives the transmission gears to rotate. The rotation of the transmission gears drives the transmission rack to move, which in turn drives the overall extension and retraction of the spray gun 20, thereby pulling the spray gun 20 to reciprocate on the motion guide rail 12. When the user needs to use the spray washing function, the spray gun 20 extends out of the cover; when the spray washing function is finished, the spray gun 20 retracts back into the cover.

[0071] It is understood that in other implementations, the transmission device may also be a chain, telescopic rod, or other transmission structure; the specific structure of the transmission device is not limited here.

[0072] Please see Figure 2 Specifically, in this embodiment, the spray gun 20 includes a gun body 21. A retaining sleeve 22 is fixedly provided on the gun body 21. The retaining sleeve 22 is engaged with the motion guide rail 12. Furthermore, the motion guide rail 12 and the mounting bracket 10 can be an integral structure. The motion guide rail 12 can be an arc-shaped protrusion or an arc-shaped guide groove formed on the mounting bracket 10.

[0073] The front end of the spray gun 20 is the water spray end, and the rear end is the mounting end. Since the mounting end of the spray gun 20 is installed inside the seat body, and the height distance between the seat body and the ceramic body is limited, and given the current trend towards thinner and lighter toilet seats, this height distance is even more limited.

[0074] The curved spray gun 20, with its arc-shaped nozzle trajectory, differs from the traditional downward-sloping straight nozzle of a smart toilet. The arc-shaped spray gun 20 extends in an arc shape onto the toilet bowl, and since the spray nozzle extends the same horizontal distance, it reaches a lower height, resulting in a larger spray area and better spraying effect. In other words, while maintaining the same spraying effect (i.e., the spray nozzle can extend to the same height), the arc-shaped spray gun 20 significantly reduces the installation height required compared to the downward-sloping straight nozzle of a traditional smart toilet. This allows for a reduction in the overall height of the spray module without altering the nozzle's extension range, facilitating a thinner toilet seat design.

[0075] Please see Figure 4 Specifically, in this embodiment, the gun body 21 includes a housing 24, a support bracket 25 disposed within the housing 24, and a flexible drive shaft 26. The housing 24 and the support bracket 25 are adapted to each other and are both arc-shaped. The support bracket 25 has an arc-shaped cavity 251 for accommodating the flexible drive shaft 26.

[0076] The water pattern switching of the spray gun 20 in this application is achieved by a flexible drive shaft 26 extending into the gun body 21 and driving the water pattern switching device 30 to rotate. The flexible drive shaft 26 is adapted to the arc shape of the gun body 21. Because the axis of the flexible drive shaft 26 is flexible and does not need to maintain high coaxiality, the flexible drive shaft 26 can achieve the driving effect of the water pattern switching device 30 within the curved arc-shaped spray gun 20, making the overall structure of the spray gun 20 simple and enhancing its stability.

[0077] The arc-shaped cavity 251 contains a support plate 252 for supporting and positioning the flexible drive shaft 26. The support plate 252 is vertically disposed within the support bracket 25. A guide hole 253 is provided on the support plate 252. The flexible drive shaft 26 is rotatably inserted through the guide hole 253.

[0078] Multiple support plates 252 can be used. These support plates 252 are distributed along the front-rear direction of the gun body 21. The flexible drive shaft 26, guided by the guide holes 253 on the support plates 252, extends from the rear end of the support bracket 25 to the front end of the support bracket 25. The flexible drive shaft 26 is curved in an arc shape, consistent with the arc shape of the gun body 21, and maintains this arc shape during rotation. The flexible drive shaft has a certain degree of elasticity, allowing it to deform and transmit rotational torque.

[0079] Please see Figure 5Specifically, in this embodiment, the flexible drive shaft 26 is an elastic shaft. The flexible drive shaft 26 can be a spring-loaded shaft. One end of the flexible drive shaft 26 is connected to the second motor 42, and the other end is connected to the water pattern switching device 30. Therefore, the second motor 42 can drive the operation of the water pattern switching device 30 through the flexible drive shaft 26.

[0080] A water nozzle 211 is provided on the side wall of the gun body 21. Specifically, the water nozzle 211 is located at the water outlet end of the outer casing 24 and faces upward towards the ceramic body. That is, the water spray direction of the spray gun 20 is directed diagonally upward towards the spray gun 20, so that the cleaning water sprayed from the water nozzle 211 can rinse the user's buttocks.

[0081] The spray gun 20 is equipped with a water delivery channel. This channel can be a separate water pipe 23, or it can be a water delivery trough or cavity integrally formed with the spray gun 20. Specifically, in this embodiment, the water delivery channel is a water pipe 23. Cleaning water used for spraying is transported within the spray gun 20 through the water pipe 23 and delivered to the water outlet of the spray gun 20. The arc-shaped cavity 251 can also be used to accommodate the water pipe 23, electrical cables, etc.

[0082] Please see Figure 4 A water pattern switching device 30 is installed at the water outlet of the spray gun 20. The water pattern switching device 30 includes a base 31, a rotating shaft 32, and a turntable 33. Different water spray patterns can be switched by rotating the rotating shaft 32. Users can choose to switch between different water spray patterns to suit their different needs. Water spray patterns can include linear, flower-shaped, polygonal, and shower-shaped patterns. It is understood that the water spray pattern is not limited to the shapes listed above and can also be other water patterns.

[0083] Please see Figure 6 The base 31 is fixedly mounted on the water outlet end of the spray gun 20. The base 31 has a water inlet channel for water passage, which is connected to the water supply pipe 23. A water outlet 310 is formed on the top end face of the water inlet channel.

[0084] The base 31 includes a rear shell 311 and a fixing plate 312. The rear shell 311 is fixedly mounted on the water outlet end of the gun body 21. The rear shell 311 can be snapped and fixed to the side wall of the gun body 21 via a snap-fit ​​connection. Please refer to [link / reference]. Figure 7 Specifically, the rear cover 311 has a latch 3111 on the side near the water outlet of the gun body 21. The water outlet of the gun body 2 has a corresponding boss 212, which can be engaged in the latch 3111 to fix the rear cover 311 to the water outlet of the gun body 21.

[0085] Please see Figure 8 and Figure 9The rear shell 311 is provided with a water-containing cavity 315. The rear shell 311 has a first channel 313 on one side of the water-containing cavity 315. The first channel 313 is connected to the water supply pipe 23.

[0086] Please see Figure 10 Furthermore, the rear cover 311 has a protruding connector 316 on the side near the gun body 21. This connector 316 can be connected to the water supply pipe 23. Then, the cleaning water enters the water-containing chamber 315 from the first channel 313 through the water supply pipe 23.

[0087] A fixed plate 312 is housed within a water-receiving cavity 315. The shape of the fixed plate 312 is adapted to the shape of the water-receiving cavity 315. A protrusion 3121 is provided on the periphery of the fixed plate 312. The fixed plate 312 is kept in a limited and fixed position within the water-receiving cavity 315 by the protrusion 3121, preventing the fixed plate 312 from rotating. Therefore, the water-receiving cavity 315 is sealed by the fixed plate 312. The cleaning water entering from the first channel 313 is contained within the water-receiving cavity 315.

[0088] Furthermore, a first sealing ring 3122 is provided on the circumferential sidewall of the fixed plate 312. The first sealing ring 3122 can maintain a sealed connection between the fixed plate 312 and the inner wall of the water-receiving cavity 315, preventing cleaning water from leaking from the gap between the fixed plate 312 and the water-receiving cavity 315. The first sealing ring 3122 can be an O-ring rubber sealing ring.

[0089] Please see Figure 11 The fixed plate 312 is provided with a second channel 314. The second channel 314 is connected to the water-receiving cavity 315. One end of the water-receiving cavity 315 is connected to the first channel 313, and the other end of the water-receiving cavity 315 is connected to the second channel 314 of the fixed plate 312. Cleaning water enters the water-receiving cavity 315 through the first channel 313 and then enters the second channel 314. Due to the increased water pressure in the water-receiving cavity 315, the cleaning water can be forced from the water-receiving cavity 315 into the second channel 314.

[0090] Specifically, in this embodiment, the second channel 314 is formed along the axial direction of the fixed plate 312. Specifically, the second channel 314 is located in the upper middle part of the fixed plate 312. The second channel 314 is closer to the water nozzle 211 of the gun body 21, facilitating water transmission. It is understood that in other embodiments, the second channel 314 may also be tortuous, as long as it can guide the cleaning water in the water-containing cavity 315 into the second channel 314 and out through it. Therefore, the water inlet channel includes a first channel 313 provided on the rear shell 311 and a second channel 314 provided on the fixed plate 312.

[0091] The bottom end face of the fixed plate 312 near the water-receiving cavity 315 is provided with an inlet of the second channel 314, so that the cleaning water enters the second channel 314 of the fixed plate 312 through the water-receiving cavity 315.

[0092] The other end face of the fixing plate 312 has an outlet for the second channel 314. Please refer to [link / reference]. Figure 12 This outlet is the water inlet 310 of the fixed plate 312. The fixed plate 312 discharges cleaning water from the second channel 314 through this water inlet 310. The water inlet 310 is formed on the surface of the fixed plate 312 near the turntable 33. The water inlet 310 is fan-shaped. This fan-shaped water inlet 310 can have a large water outlet area.

[0093] The fixed plate 312 also has a shaft hole 318 on one side of the water inlet 310. The shaft hole 318 is located at the center of the fixed plate 312. The rotating shaft 32 is rotatably inserted into the shaft hole 318, and the free end of the rotating shaft 32 passes through the fixed plate 312. A second sealing ring 323 is also provided between the rotating shaft 32 and the inner wall of the shaft hole 318. There are at least two second sealing rings 323. One second sealing ring 323 is located between the rotating shaft 32 and the rear housing 311, and the other second sealing ring 323 is located between the rotating shaft 32 and the fixed plate 312. The second sealing ring 323 can be a V-shaped sealing ring. The V-shaped sealing ring can maintain a sealed connection between the rotating shaft 32 and the rear housing 311, and between the rotating shaft 32 and the fixed plate 312, thereby preventing the cleaning water in the water-containing cavity 315 from seeping into the shaft hole 318 and ensuring the water tightness of the base 31.

[0094] The rotating shaft 32 is driven to rotate by the flexible drive shaft 26. The rotating shaft 32 is driven to rotate by the second motor 42 via the flexible drive shaft 26. Furthermore, the rotating shaft 32 maintains a rotatable connection with the fixed disk 312. When the rotating shaft 32 rotates, the fixed disk 312 remains fixed and does not rotate with the rotating shaft 32. That is, the rotational force of the rotating shaft 32 is greater than the frictional force between the rotating shaft 32 and the fixed disk 312.

[0095] The free end of the rotating shaft 32 is provided with a limiting part 321. The rotating shaft 32 passes through the turntable 33, and the limiting part 321 is limitedly connected to the turntable 33. Specifically, the limiting part 321 is provided with a step 322, and the top of the turntable 33 is provided with a limiting hole 331 that matches the step 322. When the step 322 of the limiting part 321 and the limiting hole 331 cooperate and abut against each other, the turntable 33 is limitedly connected to the rotating shaft 32. The rotating shaft 32 rotates, driving the turntable 33 to rotate.

[0096] Please see Figure 14 and Figure 15The turntable 33 is equipped with multiple water outlet valves 332 for spraying different water types. Rotation of the turntable 33 aligns the different water outlet valves 332 with the water inlet 310 and connects them to the water inlet channel. The water outlet 3321 of the water outlet valve 332 faces the side wall of the gun body 21. When the turntable 33 rotates, aligning the water outlet 3321 of one of the water outlet valves 332 with the spray nozzle 211, that water outlet valve 332 is in the spray position. Thus, the rotation of the turntable 33 allows different water outlet valves 332 to rotate to the spray position and connect with the water inlet channel, thereby enabling the spray nozzle 211 to spray different types of cleaning water.

[0097] The turntable 33 has multiple through holes 333 corresponding to multiple water outlet valves 332. Each water outlet valve 332 is connected to a corresponding through hole 333. The multiple through holes 333 are arranged in a ring. The through holes 333 and the water inlet 310 are located on the same circumference. By rotating the turntable 33, the through holes 333 corresponding to different water outlet valves 332 are adjusted to be aligned with the water inlet 310.

[0098] The cross-sectional shape of the through-hole 333 is adapted to the cross-sectional shape of the water outlet 310, so that the cleaning water enters the corresponding through-hole 333 through the water outlet 310 and then enters the corresponding outlet valve 332. When the turntable 33 rotates, the cross-section of the through-hole 333 can be fully aligned with the water outlet 310, ensuring a large flow rate and volume of the cleaning water in the through-hole 333. The through-hole 333 is fan-shaped. The water outlet 310 is also fan-shaped. The fan-shaped shapes of both the water outlet 310 and the through-hole 333 facilitate the control of the connection between the through-hole 333 and the water outlet 310 when the turntable 33 rotates.

[0099] Specifically, in this embodiment, the turntable 33 forms a blocking area 334 between two adjacent through holes 333. The central angle corresponding to the water inlet 310 is larger than the central angle corresponding to the blocking area 334. Therefore, when the turntable 33 rotates to any position, it can ensure that the water inlet 310 can be partially connected to at least one through hole 333. That is, when the turntable 33 is in any position, the cleaning water passing through the water inlet 310 can flow into a through hole 333, preventing the water inlet 310 from being completely blocked by the blocking area 334, which would cause the water pressure in the water inlet channel to increase instantaneously and cause the fixed plate 312 and the turntable 33 to be broken apart by the water pressure.

[0100] Please see Figure 15 The bottom surface of the turntable 33 and the top surface of the fixed plate 312 are kept in a surface seal, meaning that cleaning water will not seep into the space between the turntable 33 and the base 31 from between the bottom surface of the turntable 33 and the top surface of the fixed plate 312. Specifically, the bottom surface of the turntable 33 and the top surface of the fixed plate 312 are respectively formed into frosted surfaces through grinding. The frosted surfaces of the turntable 33 and the fixed plate 312 are in contact with each other, which can prevent cleaning water from penetrating into the space between the turntable 33 and the fixed plate 312.

[0101] Because the inlet 310 is connected to the through hole 333, and the through hole 333 is connected to the outlet 3321 of the outlet valve 332, the cleaning water can enter the corresponding through hole 333 from the inlet 310 under water pressure. The turntable 33 and the base 31 maintain a surface seal, preventing leakage of cleaning water between the base 31 and the turntable 33, maintaining water pressure, and ensuring smooth transmission of the cleaning water to the outlet valve 332.

[0102] Specifically, in this embodiment, each water outlet valve 332 has a different water outlet pattern. It can be understood that different water outlet valves 332 can have water outlets 3321 of different shapes. Different shapes of water outlets 3321 correspond to different water outlet patterns. For example, when the shape of the water outlet 3321 is linear, the water outlet pattern of the water outlet valve 332 is a linear water column; this linear water outlet 3321 can be straight or curved. When the shape of the water outlet 3321 is polygonal, the water outlet pattern of the water outlet valve 332 is a polygonal water column; this polygonal water outlet 3321 can be quadrilateral, pentagonal, hexagonal, etc. Furthermore, the shape of the water outlet 3321 can also be elliptical, circular, flower-shaped, or other irregular shapes. In other embodiments, the water outlet valve 332 can also achieve different water patterns through other structural forms.

[0103] Please see Figure 12 and Figure 16 Specifically, in this embodiment, the water pattern switching device 30 further includes an angle detection device 34 and a controller 35. The angle detection device 34 is used to measure the rotation angle information of the rotating shaft 32. The angle detection device 34 is electrically connected to the controller 35, and the controller 35 controls the rotation angle of the rotating shaft 32 according to the rotation angle information. Depending on the different setting positions of the different water outlet valves 332, the water outlet valves 332 are rotated to different rotation angles corresponding to the water spray position A. Then, the controller 35 can control the rotating shaft 32 to rotate at different rotation angles by controlling the second motor 42, thereby causing the water outlet valve 332 corresponding to that rotation angle to rotate to the water spray position A for water spraying. Therefore, the controller 35 can directly select the corresponding water outlet valve 332 for spraying according to different usage requirements.

[0104] Please see Figure 12Specifically, in this embodiment, the angle detection device 34 includes an angle sensor 341 and an angle disk 342 fixed on the rotating shaft 32. The angle sensor 341 is used to measure the rotation angle information of the angle disk 342. The rotation of the angle disk 342 and the rotating disk 33 is coaxial. Therefore, the rotation angle of the angle disk 342 corresponds to the rotation angle of different water outlet valves 332. The angle disk 342 has multiple wire holes 343 corresponding to different rotation angles. When the angle disk 342 rotates, the wire holes 343 corresponding to different rotation angles pass through the angle sensor 341, and the angle sensor 341 is used to measure the angle signal of the rotation angle of the angle disk 342. The angle sensor 341 determines the rotation angle of the angle disk 342 based on the angle signal, which can correspond to the water outlet valve 332 of different water types.

[0105] In other embodiments, the relative positions of the angle disk 342 and the angle sensor 341 can also be interchanged. The specific placement of the angle disk 342 and the angle sensor 341 is not limited here.

[0106] Specifically, in this embodiment, the controller 35 can be integrated into the toilet seat or it can be a remote control independent of the toilet seat. The controller 35 is communicatively connected to the angle sensor 341 and the power unit.

[0107] The water type switching device 30 corresponds to different rotation angles for the outlet valves 332 of different water types. A pre-selected water type can be input via the controller 35. Based on the correspondence between the pre-selected water type and the rotation angle of the outlet valves 332 on the turntable 33, the controller controls the rotation of the power unit. When the angle sensor 341 measures the rotation angle signal of the angle plate 342 and reaches the pre-selected water type rotation angle, the controller 35 controls the power unit to stop rotating, and the water type switching device 30 then sprays water onto the outlet valve 332 corresponding to the selected water type.

[0108] Therefore, when using the toilet, the user can select the appropriate water outlet valve 332 through the controller 35, which can enhance the ability of the switchable water spray gun assembly to meet various usage needs and make the use of the smart toilet more personalized.

[0109] For details in this embodiment, please refer to Figure 3 and Figure 17The nozzle 211 can also be elongated, and its extension direction is the same as the rotation direction of the water pattern switching device 30. Therefore, when the controller 35 controls the corresponding outlet valve 332 of the water pattern switching device 30 to rotate and align with the nozzle 211, the nozzle 211 can spray a cleaning water stream of the corresponding water pattern. Furthermore, the controller 35 can also control the outlet valve 332 to reciprocate by a certain adjustment angle A, which is smaller than the rotation angle of the next outlet valve 332. Therefore, the outlet valve 332 can swing left and right relative to the axis of the spray gun 20 within the range of this adjustment angle A.

[0110] Therefore, the aforementioned smart toilet can adjust the spray angle of the washing water flow by reciprocating the water outlet valve within adjustment angle A, enabling left and right adjustment of the spray water flow. Each time a user sits on the smart toilet, the position of the user's area to be washed relative to the water outlet of the spray gun 20 will differ. Furthermore, when different users use the smart toilet, due to differences in height, weight, gender, etc., the position of the user's area to be washed relative to the water outlet of the spray gun 20 will also differ. The aforementioned smart toilet uses a rotating shaft 32 to cause the water pattern switching device 30 to swing within the adjustment angle range, thus providing a larger spray area and ensuring accurate washing for each user, making it suitable for various users and their different needs.

[0111] Please see Figure 12 The water type switching device 30 also includes a front cover 36. The front cover 36 is detachably sealed onto the base 31, and the front cover 36 and the base 31 form a receiving cavity, in which the turntable 33 is received. A receiving groove 360 ​​is provided on the side of the front cover 36 facing the turntable 33. This receiving groove 360 ​​is used to receive the top end of the rotating shaft 32. Since the top end of the rotating shaft 32 is circular and the receiving groove 360 ​​is also circular, the top end of the rotating shaft 32 can rotate within the receiving groove 360. The receiving groove 360 ​​can limit the top end of the rotating shaft 32, preventing the rotating shaft 32 from shifting during rotation.

[0112] The front cover 36 is engaged and fixedly connected to the base 31. Specifically, the front cover 36 has retaining wings 361 on both sides, and retaining wing 361 has retaining grooves 362. The base 31 has engaging protrusions 319. The retaining wings 361 and engaging protrusions 319 engage with each other, thereby fixing the front cover 36 on the base 31.

[0113] It is understood that in other embodiments, the spray nozzle 211 can also be located on the front cover 36, meaning the spray direction of the spray gun 20 can also be towards the front of the spray gun 20. Correspondingly, the outlet 3321 of the water outlet valve 332 is also opened towards the front of the spray gun 20. The spray direction of the spray gun 20 is not limited here, as long as the spray direction can meet the user's washing needs.

[0114] For other implementations, please refer to Figure 18 The switchable water-type spray gun assembly also includes a self-cleaning structure 50. The self-cleaning structure 50 is located at the water outlet end of the spray gun. The self-cleaning structure 50 has a cleaning channel. This cleaning channel is a guide groove integrally formed on the assembly. Cleaning water enters from the water inlet end of the cleaning channel. The water inlet end of the cleaning channel faces one side of the spray gun, and a connector 51 protrudes from the water inlet end of the cleaning channel. A pipe for cleaning water can be connected to this connector 51 to supply cleaning water.

[0115] The water outlet of the cleaning channel is located above the spray gun body, and the water outlet sprays cleaning water downwards in the direction of the spray gun. Multiple water outlets can be included. These multiple water outlets are arranged sequentially above the water outlet end of the spray gun. Specifically, in this embodiment, the multiple water outlets can include side cleaning outlets located on both sides and a top cleaning outlet located in the middle. The top cleaning outlet is located at the top of the spray gun, and the cleaning water flows directly out through the top cleaning outlet, spraying and cleaning the top surface of the spray gun. The side cleaning outlets are located diagonally above the top of the spray gun, and the cleaning water is sprayed out through the side cleaning outlets, flowing to both sides of the spray gun.

[0116] Furthermore, the self-cleaning structure 50 is also equipped with an ultraviolet disinfection lamp 53. The ultraviolet disinfection lamp 53 is located above the water outlet of the spray gun 20, and the ultraviolet disinfection lamp 53 can also disinfect the spray gun 20.

[0117] Therefore, the self-cleaning structure 50 can clean the spray gun located within the cleaning chamber. Furthermore, in conjunction with the forward and backward extension and retraction of the spray gun, the cleaning structure can achieve overall cleaning of the spray gun, thereby improving the cleanliness of the spray gun assembly and enhancing the hygiene of the smart toilet.

[0118] Traditional spray guns typically have water valves on both sides. These valves are connected to the water supply for cleaning, making the cleaning structure of traditional spray guns relatively complex and bulky, which is not conducive to the development of smart toilets.

[0119] Compared to traditional spray guns, the aforementioned switchable water-type spray gun assembly, through its self-cleaning structure 50, only requires the introduction of one cleaning water path to achieve multi-angle cleaning of the spray gun's perimeter wall. This not only improves the cleaning effect, but also, the self-cleaning structure 50 has a simple structure and small size, which is conducive to the intelligent development of smart toilets.

[0120] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
