[0060] Typical implementations that embody the features and advantages of the present application will be described in detail in the following description. It should be understood that the present application can have various changes in different implementations without departing from the scope of the present application, and the descriptions and illustrations therein are essentially used for illustrative purposes rather than for limiting the present application.

[0061] The structure of a toilet is divided into three parts, namely the water tank, toilet seat and toilet lid. The water tank includes a float, a water supply pipe, an overflow pipe, a water stop valve, a box body, a water inlet ring and other structures. The toilet seat is divided into a water flow hole, a sealing ring, a water seal, a drain pipe, a toilet base and other structures. The toilet lid has two parts: a cover plate and a seat ring. In addition, the toilet also has structures such as a water supply pipe and an angle valve.

[0062] The present application provides a smart toilet, which includes a spray gun assembly and a toilet cover base, wherein the spray gun assembly is fixed on the toilet cover base. The spray gun 3 in the spray gun assembly is provided with various functions such as feminine washing, fecal washing, defecation, massage, etc. The user can control the spray gun 3 to extend to a suitable position according to the cleaning needs to clean the lower body.

[0063] like Figure 1 As shown, the spray gun assembly comprises a first housing 1 , a second housing 2 , a spray gun 3 , and a driving device 4 .

[0064] Among them, Figure 2 As shown, the first housing 1 includes a housing portion 10 and a limiting portion 11 . The limiting portion 11 is disposed at one end of the housing portion 10 .

[0065] The shell 10 is a semi-enclosed structure with an open top side and left and right ends, and a hollow space inside. The cross section of the shell 10 is roughly "U"-shaped. The limiter 11 is fixedly arranged at one end of the top side of the shell 10. The limiter 11 is in a semicircular ring shape. One end of the limiter 11 is fixedly connected to one side of the top side of the shell 10, and the other end is fixedly connected to the other side of the top side of the shell 10. One side of the limiter 11 is flush with the end of the shell 10.

[0066] The shell portion 10 and the limiting portion 11 can be fixedly connected by being connected as one body. The shell portion 10 and the limiting portion 11 can both be made of plastic material and manufactured by integral molding.

[0067] like Figure 3 and Figure 4 As shown, the second housing 2 includes a tubular portion 20 and a first protruding portion 21. The first protruding portion 21 is fixedly arranged on the outer surface of the tubular portion 20. The inner surface of the tubular portion 20 is provided with a limiting hole 201.

[0068] The tubular portion 20 may be a substantially cylindrical round tube. The tubular portion 20 has a cavity with the same outer contour as the tubular portion 20, which extends to both ends of the tubular portion 20 and has openings at the end positions.

[0069] The first protrusion 21 is in a tile-like shape, and is protruded from the outer surface of the tubular portion 20 and is arranged coplanar with the outer surface of the tubular portion 20. The two ends of the tubular portion 20 are respectively a first end and a second end. The first protrusion 21 is close to the first end of the tubular portion 20, and the first protrusion 21 is flush with the first end.

[0070] like Figure 4 As shown, the second housing 2 further includes an inner convex portion 22 convexly disposed on the inner surface of the tubular portion 20. The inner convex portion 22 is preferably an inner flange convexly disposed on the inner surface of the tubular portion 20, and one end of the inner convex portion 22 extends to the second end of the tubular portion 20 and is flush with the second end. A limiting hole 201 is provided on the inner convex portion 22.

[0071] The second shell 2 may be made of plastic material, so that the tubular portion 20, the first protruding portion 21, and the inner protruding portion 22 may be manufactured by integral molding, and the tubular portion 20, the first protruding portion 21, and the inner protruding portion 22 are connected as one.

[0072] like Figure 5 As shown, the spray gun 3 includes a spray gun body 30 and an elastic limiting unit 31. The elastic limiting unit 31 is embedded in the outer surface of the spray gun body 30.

[0073] The spray gun body 30 is generally cylindrical in shape, the front end of the spray gun body 30 is a working end, and the nozzle is arranged at the front end of the spray gun body 30. A radial blind hole 301 is provided on the outer surface of the spray gun body 30 near the rear end, and the elastic limiting unit 31 is embedded in the blind hole 301.

[0074] The driving device 4 is drivingly connected to the second housing 2 and the spray gun 3. The second housing 2 is telescopically slidably mounted in the housing portion 10. The first protrusion 21 can abut against the limiting portion 11 as the second housing 2 slides to limit the extension of the second housing 2.

[0075] The spray gun 3 is telescopically and slidably installed in the tubular portion 20 , and the elastic limiting unit 31 can cooperate with the limiting hole 201 as the spray gun 3 slides to limit the extension movement of the spray gun 3 .

[0076] The spray gun 3 may further include a second protrusion 32 , which is fixed to the outer surface of the spray gun body 30 and located at the rear end of the spray gun body 30 .

[0077] The second protrusion 32 is preferably an outer flange protruding from the outer surface of the spray gun body 30 , and one end of the second protrusion 32 extends to the rear end of the spray gun body 30 and is flush with the rear end.

[0078] The inner diameter of the tubular portion 20 is equal to or slightly larger than the outer diameter of the second protrusion 32, and the inner diameter of the inner protrusion 22 is slightly larger than the outer diameter of the spray gun body 30. As the spray gun 3 extends out of the tubular portion 20, the second protrusion 32 can abut against the inner protrusion 22 as the spray gun 3 slides to limit the extension of the spray gun 3.

[0079] like Figure 6 As shown, the elastic limiting unit 31 includes an elastic member 310 and a pin head 311. The elastic member 310 is embedded in the blind hole 301. The pin head 311 is pressed on the elastic member 310. During the sliding process of the spray gun 3 relative to the tubular portion 20, the pin head 311 can be pressed into the blind hole 301 by the inner surface of the tubular portion 20. As the spray gun 3 slides, the pin head 311 can be pushed out by the elastic member 310 to the outer surface of the spray gun body 30 to engage with the limiting hole 201.

[0080] It is understandable that the elastic member 310 can be a coil spring. The elastic member 310 is embedded in the blind hole 301, and the axial direction of the elastic member 310 is the same as the depth extension direction of the blind hole 301. One end of the elastic member 310 close to the outer surface of the spray gun body 30 is fixedly connected to the pin head 311.

[0081] The surface of the pin head 311 that contacts the limiting hole 201 is a curved surface, such as a spherical crown surface. Of course, it is conceivable that the pin head 311 can also be a spherical head, or an ellipsoid, etc.

[0082] In addition to the above-mentioned coil spring, the elastic member 310 may also be a polyurethane spring or the like.

[0083] In addition, the elastic limiting unit 31 may also adopt a gas spring structure, and the push rod in the gas spring may replace the pin head 311 to be engaged with the limiting hole 201 .

[0084] like Figure 6 As shown, the tubular portion 20 is provided with an axially extending notch 202 , the notch 202 is located on one side of the tubular portion 20 , the limiting portion 11 is located on the other side of the tubular portion 20 , and the notch 202 and the limiting portion 11 are arranged opposite to each other.

[0085] The driving device 4 includes a screw rod 41 , a driving element 42 , a first nut portion 43 and a second nut portion 44 .

[0086] The screw rod 41 is rotatably connected to the housing portion 10 , and the screw rod 41 is located at the lower inner side of the housing portion 10 . The driving element 42 is drivingly connected to the screw rod 41 .

[0087] The first nut portion 43 is fixedly disposed on the outer surface of the tubular portion 20 and is threadedly sleeved on the screw rod 41. The first nut portion 43 can be close to the first end of the tubular portion 20 and flush with the first end. The first nut portion 43 is disposed opposite to the limiting portion 11.

[0088] The second nut portion 44 is fixedly disposed on the outer surface of the spray gun body 30. The second nut portion 44 can be fixedly disposed on the second protrusion 32 at the rear end of the spray gun body 30. Figure 6 The second nut portion 44 passes through the notch 202 and is screwed onto the screw rod 41 .

[0089] The driving element 42 is preferably an electric motor, and the output shaft of the driving element 42 is drivingly connected to one end of the screw rod 41 .

[0090] The two ends of the screw rod 41 are respectively a first end and a second end. The first housing 1 further includes a support portion 12, which is fixedly connected to the lower side of the housing portion 10 and disposed near one end of the housing portion 10. A through hole is provided through the support portion 12, and the first end of the screw rod 41 passes through the through hole and is transmission-connected to the output shaft of the driving element 42.

[0091] The housing of the driving element 42 can be fixedly connected to the housing portion 10 by screws. In addition to using an electric motor, the driving element 42 can also use a pneumatic motor.

[0092] In some embodiments, Figure 7As shown, the first housing 1 further includes a baffle 13 protruding from the inner surface of the housing 10. The baffle 13 is preferably a fully enclosed annular member or a semi-enclosed U-shaped member. The baffle 13 is fixed to the lower side of the housing 10. The screw 41 is surrounded by the baffle 13. The baffle 13 can block the edge of the first nut 43, and play a certain role in limiting the movement of the first nut 43.

[0093] In the initial stage when the driving element 42 drives the screw rod 41 to rotate in the first direction, the blocking portion 13 can limit the movement of the first nut portion 43 so that the second nut portion 44 drives the spray gun 3 to extend first.

[0094] In some embodiments, Figure 8 As shown, the spray gun 3 further comprises a guide post 33 fixedly arranged on the outer surface of the spray gun body 30. A guide groove 101 which is slidably matched with the guide post 33 is provided on the inner surface of the housing portion 10.

[0095] The guide column 33 and the guide groove 101 together form a guide structure. When the spray gun 3 slides relative to the housing portion 10, the guide structure plays an effective guiding role.

[0096] The initial position of the spray gun assembly is as follows: Figure 6 When the driving element 42 drives the screw 41 to rotate in the forward direction, the torque applied by the screw 41 to the first nut portion 43 is less than the resistance of the barrier portion 13 to the first nut portion 43. Therefore, the second housing 2 is restricted from moving under the action of the barrier portion 13, and the first nut portion 43 on the tubular portion 20 in the second housing 2 does not contact the screw thread of the screw 41, so that the second housing 2 does not move.

[0097] As the screw rod 41 rotates forward, the spray gun 3 is pushed out of the second housing 2 driven by the second nut portion 44 .

[0098] The spray gun 3 slowly extends out of the second housing 2. During the sliding movement of the spray gun 3 relative to the tubular portion 20, the pin head 311 can be pressed into the blind hole 301 by the inner surface of the tubular portion 20. As the spray gun 3 slides, the pin head 311 can be pushed out to the outer surface of the spray gun body 30 by the elastic member 310 to engage with the limiting hole 201.

[0099] When the pin head 311 is engaged with the limiting hole 201 , the second protrusion 32 can abut against the inner protrusion 22 , and the spray gun 3 is extended to the limit position relative to the second housing 2 .

[0100] As the screw 41 rotates forward, under the dual effects of the engagement between the pin head 311 and the limiting hole 201 and the abutment between the second protrusion 32 and the inner protrusion 22, the spray gun 3 pulls the second shell 2, so that the first nut portion 43 breaks through the restriction of the blocking portion 13, the first nut portion 43 is threadedly connected to the screw 41, and the second shell 2 is extended from the shell body 10 driven by the first nut portion 43.

[0101] Since the spray gun 3 and the second housing 2 are fixedly connected by the engagement of the pin head 311 and the limiting hole 201 , the spray gun 3 continues to move with the second housing 2 .

[0102] When the first protrusion 21 abuts against the limiting portion 11, the second housing 2 extends to the limit position relative to the housing 10. The extension of the second housing 2 and the spray gun 3 is completed, and the spray gun 3 can perform a spray cleaning operation.

[0103] When the driving element 42 drives the screw 41 to rotate in the reverse direction, the spray gun 3 and the second housing 2 enter the return stage.

[0104] Driven by the first nut portion 43 , the second housing 2 retracts into the housing portion 10 .

[0105] Because the spray gun 3 and the second housing 2 are fixedly connected by the engagement of the pin head 311 and the limiting hole 201 , the spray gun 3 starts the return movement along with the second housing 2 .

[0106] When the spray gun 3 moves back along with the second housing 2 , the second nut portion 44 and the screw rod 41 are threadedly connected again.

[0107] After the spray gun 3 moves back a distance along with the second housing 2, the second protrusion 32 separates from the inner protrusion 22. The torque applied by the screw 41 to the second nut portion 44 enables the pin head 311 to be disengaged from the limiting hole 201. As the screw 41 continues to reverse, the spray gun 3 is retracted into the second housing 2 under the drive of the second nut portion 44. During the process of the spray gun 3 retracting and sliding relative to the tubular portion 20, the pin head 311 can be pressed into the blind hole 301 by the inner surface of the tubular portion 20.

[0108] As the first nut portion 43 retreats to the rear of the baffle portion 13, the second housing 2 and the spray gun 3 retract to the initial position. The second housing 2 and the spray gun 3 wait for the next extension instruction. When the driving element 42 drives the screw 41 to rotate forward, the baffle portion 13 continues to limit the movement of the first nut portion 43.

[0109] The smart toilet and its spray gun assembly in the present application adopt a two-stage telescopic structure of the second shell 2 and the spray gun 3, which realizes low-noise telescopic movement of the spray gun, occupies less space, and realizes motion control of the second shell 2 and the spray gun 3 through elastic limit units and limit holes. The spray gun assembly in the present application has a reasonable structure and stable operation, which overcomes the defects of the related art such as high gear transmission noise, virtual position, unstable transmission and easy tooth slipping of belt transmission.

[0110] Although the present application has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present application can be implemented in a variety of forms without departing from the spirit or essence of the application, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
