DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings. The terms used in the embodiment part of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0037] Figs. 1 to 6 are views of the first embodiment of the present application, which provides a submerged spray washing mechanism of a smart toilet, comprising a toilet seat 1 and a spray washing mechanism 3 arranged at the front side of the toilet seat 1. The front side bottom of the toilet seat 1 is provided with a mounting chamber 2 for mounting the spray washing mechanism 3. One end of the spray washing mechanism 3 is provided with a rotating shaft 38 rotationally connected with the mounting chamber 2. The whole spray washing mechanism 3 can rotate back and forth around the rotating shaft 38 as the axis. The spray washing mechanism 3 also has a rotating structure for driving the spray washing mechanism 3 to rotate around the rotating shaft 38, and a movable body 32 which can be extended and retracted. The movable body 32 is provided with a water spraying port. When the spray washing mechanism 3 rotates downward around the rotating shaft 38, it moves out of the mounting chamber 2. After the movable body is extended and retracted, the water spraying port is lowered to a set position. When the movable body is retracted and the movable body 32 is reset upward, the spray washing mechanism 3 is accommodated into the mounting chamber 2.

[0038] The submerged spray washing mechanism of the present embodiment is mounted at the front end of the toilet seat. Compared with mounting the spray washing mechanism at the rear end of the toilet seat, it can reduce the pollution of the flushing water flow. Moreover, a rotating shaft is arranged at one end of the spray washing mechanism to rotate. When the movable body is ready for water spraying, the rotating structure pushes the whole spray washing mechanism to rotate downward, and the movable body is extended and retracted. In this way, the sinking distance L of the movable body relative to the toilet ceramic body is long. The inventor of the present application found through many studies that the sinking distance L of the movable body should be at least more than 10 cm. In this way, the spray washing mechanism can spray both the female user's private parts and the rear end buttocks. Moreover, after the movable body is retracted and the spray washing mechanism is reset, it can be hidden in the space of the mounting chamber, which is more beautiful and hygienic.

[0039] When the movable body 32 is extended, the extension force of the movable body 32 can push the whole spray washing mechanism 3 to rotate downward to achieve the sinking. When the movable body is extended, it can push the spray washing mechanism 3 to rotate, so that the driving source can be reduced and the cost can be lowered.

[0041] The spray washing mechanism 3 further includes a spray washing body 31, a rotating shaft 38 is arranged on the spray washing body 31, the spray washing body 31 is provided with a telescopic guide rail 311, the movable body 32 is slidably connected on the telescopic guide rail 311, the spray washing body 31 is further provided with a guide ring 312 sleeved on the outer periphery of the movable body 32, the telescopic structure includes a motor, a gear arranged on the output shaft of the motor, a toothed belt cooperated with the gear, the toothed belt is fixed with the movable body 32, the toothed belt slides along the track of the telescopic guide rail 311, so that when the gear rotates, the toothed belt and the movable body 32 can move along the telescopic guide rail 311.

[0042] The opening 21 of the installation chamber 2 is further rotatably connected with a cover plate 4 for opening and closing the opening 21, the movable body 32 can push the cover plate 4 to open downward when the movable body 32 is extended, the installation chamber 2 and the cover plate 4 are further connected with a second elastic reset member for driving the cover plate 4 to reset reversely.

[0043] The movable body 32 performs the spray washing work in the way of reciprocating extension and contraction during the spray washing work.

[0044] The working process of this embodiment is as follows: first, the motor drives the gear to rotate, drives the toothed belt to move, and drives the movable body 32 to extend, the guide pin 34 on the movable body 32 moves in the guide groove 351, so that the movable body 32 can rotate downward while extending, so as to achieve the purpose of sinking, then the motor reciprocates at a small amplitude, the movable body 32 moves in extension and contraction, so that the movable body 32 can perform the reciprocating spray washing work.

[0045] Fig. 7 to Fig. 9 show another embodiment of the present application, the main difference between this embodiment and the first embodiment is the different rotating structure. The rotating structure of this embodiment includes a protruding part 36 fixedly arranged on the movable body 32 and a roller 37 rotatably connected in the installation chamber 2, when the movable body 32 is extended, the protruding part 36 is pressed by the roller 37 to push the movable body 32 to rotate downward.

[0046] In order to realize automatic cleaning, the convex part 36 is fixedly arranged at the middle part of the movable body 32, the guide ring 312 is provided with a gap 3121 for the extension and contraction of the convex part 36, the movable body 32 is provided with a water spraying opening which is open upward, and the end of the convex part 36 close to the water spraying opening is fixedly arranged with a shielding cover 361 which can move in the gap 3121 and cover the water spraying opening. The water spraying opening is located below the shielding cover, so that when the water spraying opening sprays water to the shielding cover, the water flow can be self-cleaned, but the length of the shielding cover is very short and does not affect the water spraying work.

[0047] Figure 10 shows another embodiment of the present application, which is mainly different from the first embodiment in that the rotating structure of the present embodiment is a first motor 39 connected with the rotating shaft.

[0048] Referring to Figures 11 to 14, another embodiment of the present application is provided, which is a submerged water spraying mechanism of an intelligent toilet, comprising a toilet seat 1 and a water spraying mechanism 3 arranged at the front side of the toilet seat 1. The front side of the toilet seat 1 is provided with a mounting cavity 2 for mounting the water spraying mechanism 3. One end of the water spraying mechanism 3 is provided with a rotating shaft 38 which is rotationally connected with the mounting cavity 2.

An elastic reset member 323 is arranged in the body of the telescopic pipe 321 and connected between the telescopic pipe 321 and the water spraying body 31. When water is supplied to the water passage, the telescopic pipe 321 can extend under the action of water pressure. When there is no water supply, the telescopic pipe 321 can be automatically reset under the reverse action of the elastic reset member. The water spraying opening is arranged on the telescopic pipe 321. This mode mainly drives the telescopic pipe to extend by the impact of water flow. The elastic reset member 323 can be a tension spring or a compression spring.

[0051] The movable body 32 is reciprocatingly washed during the water spraying work. The reciprocating washing mode is that the movable body 32 swings forward and backward around the rotating shaft.

[0052] The installation chamber 2 has a downward opening 21, and a cover plate 4 is arranged at the opening for opening and closing the opening 21, and the cover plate 4 is fixedly connected to the movable body 32.

[0053] The working flushing working process of this embodiment is as follows: water is filled into the telescopic pipe 321, the telescopic pipe is blocked by the limiting part 22 and cannot be stretched out, the water jet nozzle 322 sprays water, and the water flow falls on the water jet nozzle 322 for cleaning. In the second step, the first motor 39 drives the telescopic pipe 321 to rotate downward, which is called sinking swing, the telescopic pipe 321 is stretched out under the pressure of the water flow, and then the first motor 39 reversely rotates, drives the stretched telescopic pipe 323 to rotate around the rotating shaft 38, which is called flushing swing, so that the water jet nozzle on the telescopic pipe 321 performs reciprocating spraying and washing work. Thus, the female user's genital area and the buttocks can be sprayed and washed.
