In addition, the toilet also has structures such as a water supply pipe and an angle valve.

[0067] The present application provides an intelligent toilet, which includes a spray gun assembly and a toilet lid base. Among them, the spray gun assembly is fixed on the toilet lid base. The spray gun 3 in the spray gun assembly is provided with various different functions such as feminine wash, bidet wash, constipation relief, 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.

[0068] As Figure 1 shown, the above spray gun assembly includes a first outer shell 1, a second outer shell 2, a spray gun 3, and a driving device 4.

[0069] Among them, as Figure 2 and Figure 3 shown, the first outer shell 1 includes a shell portion 10 and a first magnetic member 11. The first magnetic member 11 is fixed inside the shell portion 10.

[0070] The shell portion 10 is a semi-surrounding structure with an open top side and left and right ends, and the inside is a hollow space. The cross-section of the shell portion 10 is generally in a "U" shape.

[0071] The first housing 1 further includes a first support portion 12 and a second support portion 13.

Among them, the first support portion 12 is provided near one end of the housing portion 10, and the second support portion 13 is provided near the other end of the housing portion 10. The first support portion 12 and the second support portion 13 are oppositely arranged inside the housing portion 10. Moreover, a first support hole 120 is penetrated through the first support portion 12, and a second support hole 130 is penetrated through the second support portion 13. The first support hole 120 and the second support hole 130 are oppositely arranged, and the extending direction of the central connection line of the first support hole 120 and the second support hole 130 is the same as the extending direction of the housing portion 10.

[0072] The housing portion 10, the first support portion 12, and the second support portion 13 can be fixedly connected by being integrally formed. The housing portion 10, the first support portion 12, and the second support portion 13 can all be made of plastic material and be formed by an integral molding method.

[0073] As Figure 4 shown, the first magnetic member 11 includes two strip-shaped magnets 110, and these two are embedded in the first support portion 12. Moreover, one strip-shaped magnet 110 is provided on each of the left and right sides of the first support hole 120.

[0074] As Figure 5 shown, the first housing 1 further includes a fifth magnetic member 14 fixedly provided inside the housing portion 10. The fifth magnetic member 14 includes two strip-shaped magnets 140, and these two are embedded in the second support portion 13. One strip-shaped magnet 140 is provided on each of the left and right sides of the second support hole 130. The two strip-shaped magnets 140 are symmetrically arranged with respect to the center of the second support hole 130.

[0075] As Figure 6 and Figure 7 shown, the second housing 2 includes a tubular portion 20, a second magnetic member 21, and a third magnetic member 22. Among them, the second magnetic member 21 is fixedly provided on the inner surface of the tubular portion 20, and the third magnetic member 22 is fixedly provided on the outer surface of the tubular portion 20.

[0076] The tubular portion 20 can be a generally cylindrical circular tube. A cavity having the same outer contour as its own is provided inside the tubular portion 20, and the cavity extends to both ends of the tubular portion 20 and openings are formed at the end positions. The two ends of the tubular portion 20 are respectively a first end and a second end. An axially extending notch 201 is formed on the tube wall of the tubular portion 20.

[0077] The second magnetic member 21 can be a rectangular block-shaped magnet, which is embedded in the inner surface of the tubular portion 20 and is provided near the first end. The second magnetic member 21 is arranged opposite to the notch 201.

[0078] In addition, the second housing 2 further includes a first nut portion 23 fixedly provided on the outer surface of the tubular portion 20. The first nut portion 23 is located at the first end of the tubular portion 20, and the first nut portion 23 and the notch 201 are located on the same side of the tubular portion 20.

[0079] The third magnetic member 22 includes two strip-shaped magnets 220, which are embedded in the first nut portion 23. Moreover, one strip-shaped magnet 220 is provided on each of the left and right sides of the threaded hole in the first nut portion 23. The two strip-shaped magnets 220 are symmetrically arranged with respect to the center of the threaded hole.

[0080] The second housing 2 can be made of plastic material. In this way, the tubular portion 20 and the first nut portion 23 can be obtained by an integral molding method.

[0081] As Figures 8 to 10 shown, the spray gun 3 includes a spray gun body 30 and a fourth magnetic member 31. Among them, the spray gun body 30 is generally cylindrical as a whole, the front end of the spray gun body 30 is the working end, and the nozzle is provided at the front end of the spray gun body 30.

[0082] The fourth magnetic member 31 is fixedly provided on the outer surface of the spray gun body 30. The fourth magnetic member 31 can be a rectangular block-shaped magnet, which is embedded in the outer surface of the spray gun body 30 and is arranged close to the rear end of the spray gun body 30.

[0083] Furthermore, the spray gun 3 further includes a second nut portion 32 clamped on the outer surface of the spray gun body 30 and a sixth magnetic member 33 embedded in the second nut portion 32.

[0084] As Figure 9 shown, the spray gun 3 further includes a first limiting portion 34 and a second limiting portion 35 protruding from the outer surface of the spray gun body 30 and arranged at intervals. The second nut portion 32 is clamped in the interval between the first limiting portion 34 and the second limiting portion 35.

[0085] Both the first limiting portion 34 and the second limiting portion 35 are plate-shaped, and both are embedded in the outer surface of the spray gun body 30. The first limiting portion 34 and the second limiting portion 35 are arranged opposite to the fourth magnetic member 31, and there is an interval between the first limiting portion 34 and the second limiting portion 35. The second nut portion 32 is clamped in the interval between the first limiting portion 34 and the second limiting portion 35, and the axis of the second nut portion 32 is parallel to the axis of the spray gun body 30.

[0086] As Figure 10 shown, the sixth magnetic member 33 includes two strip-shaped magnets 330, which are embedded in the second nut portion 32. Moreover, one strip-shaped magnet 330 is provided on each of the left and right sides of the threaded hole in the second nut portion 32. The two strip-shaped magnets 330 are symmetrically arranged with respect to the center of the threaded hole.

[0087] As Figure 11 shown, the driving device 4 is drivingly connected to the second housing 2 and the spray gun 3. The driving device 4 includes a screw 40 and a driving element 41. The screw 40 is rotatably connected within the housing portion 10 and is drivingly connected to the driving element 41.

[0088] The second housing 2 is telescopically and slidably installed within the housing portion 10. In the sliding direction of the second housing 2, the third magnetic member 22 can be magnetically connected to the first magnetic member 11.

[0089] The spray gun 3 is telescopically and slidably installed within the tubular portion 20. The fourth magnetic member 31 can be attracted to the second magnetic member 21, so that the spray gun 3 is kept connected to the second housing 2, so that the spray gun 3 telescopically slides with the second housing 2.

[0090] The second nut portion 32 on the outer surface of the spray gun body 30 passes through the notch 201 on the tubular portion 20 and is screwed onto the screw 40.

[0091] As the spray gun 3 extends and slides relative to the tubular portion 20, the sixth magnetic member 33 within the second nut portion 32 can be attracted to the fifth magnetic member 14 within the second support portion 13, and the second nut portion 32 can be separated from the spray gun body 30; as the spray gun 3 retracts and slides relative to the tubular portion 20, the sixth magnetic member 33 within the second nut portion 32 can be disengaged from the fifth magnetic member 14 within the second support portion 13, and the second nut portion 32 can be snapped onto the first limiting portion 34 and the second limiting portion 35 on the outer surface of the spray gun body 30 again.

[0092] As Figure 12 shown, one end of the screw 40 is rotatably connected within the first support hole 120 in the first support portion 12, and the other end of the screw 40 is rotatably connected within the second support hole 130 in the second support portion 13.

[0093] The driving element 41 can be an electric motor. The end of the screw 40 passes through the first support hole 120 and is drivingly connected to the output shaft of the driving element 41.

[0094] As Figure 11 and Figure 12 shown, the spray gun assembly further includes a guide rod 5. The guide rod 5 is fixedly installed within the housing portion 10, and the guide rod 5 is arranged parallel to the screw 40. The first nut portion 23 and the second nut portion 32 are slidably connected to the guide rod 5.

[0095] The first nut portion 23 is axially provided with a first through hole 230. The first through hole 230 is arranged parallel to the threaded hole of the first nut portion 23, and the first through hole 230 is eccentrically arranged relative to the central axis of the first nut portion 23.

[0096] The second nut portion 32 is axially penetrated with a second through hole 320, which is arranged parallel to the threaded hole of the second nut portion 32, and the second through hole 320 is eccentrically arranged relative to the central axis of the second nut portion 32.

[0097] The guide rod 5 is inserted into the first through hole 230 and the second through hole 320, so that the first nut portion 23 and the second nut portion 32 can slide along the guide rod 5.

[0098] The guide rod 5 is located below the screw rod 40. Before the sixth magnetic member 33 is attracted to the fifth magnetic member 14, the second nut portion 32 slides down along the guide rod 5.

[0099] After the second nut portion 32 descends along the guide rod 5, the sixth magnetic member 33 in the second nut portion 32 can be attracted to the fifth magnetic member 14. When the spray gun 3 slides with the second housing 2, the second nut portion 32 can be separated from the first limiting portion 34 and the second limiting portion 35 on the spray gun body 30. As the spray gun 3 and the second housing 2 further extend outwards relative to the housing portion 10, the second limiting portion 35 can be separated from the second nut portion 32.

[0100] The screw rod 40 includes a threaded section 400 and a smooth rod section 401 arranged in sequence. The diameter of the smooth rod section 401 is smaller than that of the threaded section 400. The end of the threaded section 400 passes through the first support hole 120 and is in transmission connection with the output shaft of the driving element 41. The smooth rod section 401 is arranged by means of the fifth magnetic member 14 in the second support portion 13.

[0101] When the second nut portion 32 moves from the threaded section 400 to the smooth rod section 401 along with the rotation of the screw rod 40, since the diameter of the smooth rod section 401 is smaller than that of the threaded section 400, it is convenient for the second nut portion 32 to descend.

[0102] As Figure 12 shown, the guide rod 5 includes a first horizontal rod portion 50, a second horizontal rod portion 51, and an inclined rod portion 52 obliquely connected between the first horizontal rod portion 50 and the second horizontal rod portion 51. The inclined rod portion 52 is located below the smooth rod section 401, and the inclined rod portion 52 is inclined obliquely downwards.

[0103] When the second nut portion 32 moves from the threaded section 400 to the smooth rod section 401 along with the rotation of the screw rod 40, the second nut portion 32 slides down along the inclined rod portion 52, so as to realize sliding down along the guide rod 5.

[0104] In order to cooperate with the sliding down of the second nut portion 32 along the inclined rod portion 52, the second through hole 320 for the guide rod 5 to pass through on the second nut portion 32 is a tapered hole extending axially. The taper of the tapered hole is adapted to the slope of the inclined rod portion 52.

[0105] In some embodiments, as Figure 13As shown, the spray gun 3 further includes a guide post 36 fixedly provided on the outer surface of the spray gun body 30. A guide groove 101 which is in guiding and sliding cooperation with the guide post 36 is provided on the inner surface of the housing portion 10.

[0106] The guide post 36 and the guide groove 101 together constitute a guiding structure, which plays an effective guiding role when the spray gun 3 slides relative to the housing portion 10.

[0107] The initial position of the above spray gun assembly is as Figure 1 shown. When the driving element 41 drives the screw 40 to rotate forward, the first magnetic member 11 and the third magnetic member 22 are attracted to each other. Since the torque applied by the screw 40 to the first nut portion 23 is less than the magnetic attraction force between the first magnetic member 11 and the third magnetic member 22, the second housing 2 is restricted from moving under the action of the magnetic attraction force, and the first nut portion 23 on the tubular portion 20 in the second housing 2 is not in threaded contact with the screw 40, so that the second housing 2 does not move.

[0108] As the screw 40 rotates forward, the spray gun 3 is pushed out of the second housing 2 by the second nut portion 32.

[0109] The spray gun 3 slowly extends out of the second housing 2. When the fourth magnetic member 31 and the second magnetic member 21 are attracted to each other, the spray gun 3 extends relative to the second housing 2 to the limit position.

[0110] As the screw 40 continues to rotate forward, the spray gun 3 pulls the second housing 2, so that the first magnetic member 11 and the third magnetic member 22 are disengaged from the attraction, the first nut portion 23 is threadedly connected to the screw 40, and the second housing 2 is pulled out of the housing portion 10 by the first nut portion 23.

[0111] Since the spray gun 3 is fixedly connected to the second housing 2 by the attraction of the fourth magnetic member 31 and the second magnetic member 21, the spray gun 3 continues to move with the second housing 2.

[0112] As the screw 40 rotates, the second nut portion 32 slides to the smooth rod section 401, and at the same time, the second nut portion 32 slides downward along the inclined rod portion 52. The sixth magnetic member 33 in the second nut portion 32 and the fifth magnetic member 14 in the second support portion 13 are attracted to each other, and the second nut portion 32 stops sliding.

[0113] As the screw 40 continues to rotate, the spray gun 3 and the second housing 2 continue to extend outwards. Since the second nut portion 32 has descended a small distance, the second limiting portion 35 on the spray gun body 30 can slide over the second nut portion 32, enabling the spray gun 3 and the second housing 2 to extend out smoothly.

[0114] When the first nut portion 23 abuts against the second nut portion 32, the second housing 2 extends relative to the housing portion 10 to the extreme position. The extension movements of the second housing 2 and the spray gun 3 are completed, and the spray gun 3 can perform the spray cleaning operation.

[0115] When the driving element 41 drives the screw 40 to rotate in the reverse direction, the spray gun 3 and the second housing 2 enter the return stroke stage.

[0116] Driven by the first nut portion 23, the second housing 2 retracts into the housing portion 10.

[0117] Since the spray gun 3 is fixedly connected to the second housing 2 by the attraction between the fourth magnetic member 31 and the second magnetic member 21, the spray gun 3 starts the return stroke movement along with the second housing 2.

[0118] During the process of the spray gun 3 retracting along with the second housing 2, the first limiting portion 34 on the spray gun body 30 contacts the second nut portion 32.

[0119] As the screw 40 continues to rotate in the reverse direction, the second nut portion 32 rises along the inclined rod portion 52 and is finally clamped within the interval between the first limiting portion 34 and the second limiting portion 35 of the spray gun body 30. At the same time, the second nut portion 32 is threadedly connected to the threaded section 400 again.

[0120] After the spray gun 3 moves back a certain distance along with the second housing 2, since the torque applied by the screw 40 to the second nut portion 32 is greater than the magnetic attraction force between the fourth magnetic member 31 and the second magnetic member 21, the fourth magnetic member 31 and the second magnetic member 21 are disengaged from the attraction. As the screw 40 continues to rotate in the reverse direction, driven by the second nut portion 32, the spray gun 3 retracts into the second housing 2.

[0121] As the first magnetic member 11 and the third magnetic member 22 are attracted, the second housing 2 retracts into the housing portion 10. When the second nut portion 32 abuts against the first nut portion 23, the spray gun 3 retracts into the second housing 2. Both the spray gun 3 and the second housing 2 retract to the initial position, waiting for the next extension instruction.

[0122] In the intelligent toilet and its spray gun assembly in this application, a two-stage telescopic structure of the second housing 2 and the spray gun 3 is adopted, realizing low-noise telescopic movement of the spray gun, occupying less space, and achieving the movement control of the second housing 2 and the spray gun 3 through the magnetic attraction structure. The spray gun assembly in this application has a reasonable structure and stable operation, overcoming the defects of large noise in gear transmission, virtual positions, unstable transmission, and easy slipping of teeth in belt transmission in the related art.

[0123] While the present application has been described with reference to several exemplary embodiments, it should be understood that the terms used are descriptive and exemplary rather than restrictive. Since the present application can be embodied in many forms without departing from the spirit or essence of the application, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be construed broadly within the spirit and scope defined by the appended claims. Accordingly, all variations and modifications that fall within the scope of the claims or their equivalents should be covered by the appended claims.
