In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] Figure 1 The specific embodiment of the toilet seat provided by the present invention is shown, which comprises: a seat body 10 having a receiving cavity, the inner wall of the seat body 10 being provided with an opening communicating with the receiving cavity; at least one flushing mechanism 20 installed in the receiving cavity to realize the flushing function of the seat 100. The seat also has functions such as warming and sterilization, and a control button 30 is arranged on the seat 100, and the user can realize different functions by triggering different control buttons 30. Among them, the flushing mechanism 20 can be installed in the front cavity of the seat body 10 to realize the flushing of the female genitals, and can also be installed in the rear cavity of the seat body 10 to realize the flushing of the anus, or installed at the front and rear sides of the seat body 10 at the same time. Among them, the "front end" of the flushing mechanism 20 of the present invention and its components refers to the water outlet end close to the internal water flow direction thereof, and the "rear end" refers to the water inlet end close to the internal water flow direction thereof.

[0040] like Figure 2-Figure 4 As shown, the flushing mechanism 20 includes an outer sleeve 22 fixedly connected to the inner wall of the seat ring body 10, a water inlet 22a is arranged at the rear end of the outer sleeve 22, and a first opening is arranged at the front end of the outer sleeve 22; an inner sleeve 23 slidably connected to the inside of the outer sleeve 22, and a second opening is arranged at the front end of the inner sleeve 23; and a nozzle 21 connected to the second opening of the inner sleeve 23, the inner sleeve 23 can slide along the outer sleeve 22, so that the nozzle 21 can be extended and retracted relative to the seat ring body 10; when the nozzle 21 is in an extended state, the cleaning liquid in the water tank 300 enters the outer sleeve 22 and the inner sleeve 23 through the water inlet 22a of the outer sleeve 22, and is finally sprayed out through the nozzle 21 to achieve cleaning of the private parts of the human body.

[0041] A drainage groove 22b is provided on the part of the tube wall where the outer sleeve 22 and the inner sleeve 23 are slidably matched, and the liquid between the outer sleeve 22 and the inner sleeve 23 can be discharged along the drainage groove 22b. When the user triggers the control button 30 to make the flushing mechanism 20 perform a flushing operation, the inner sleeve 23 is first driven to extend. At this time, when the pressure at the water inlet end is relatively low, the inner sleeve 23 has not been fully extended, and the water between the inner sleeve 23 and the outer sleeve 22 can be discharged into the toilet through the drainage groove 22b. This avoids the problem of too much cold water between the inner and outer sleeves, resulting in cold water in the front part of the water spray.

[0042] Specifically, the extension and retraction of the inner sleeve 23 can be achieved by a driving mechanism, such as a cylinder, a piston, a motor, etc. It can also be achieved by water pressure driving and a reset member driving. In this embodiment, a structure is shown in which the inner sleeve 23 is extended by water pressure and reset by the reset member.

[0043] like Figure 3 , Figure 4 As shown, the end of the inner sleeve 23 located inside the outer sleeve 22 is connected to the end cover 24, and the end cover 24 is provided with a connecting hole, and the liquid in the outer sleeve 22 enters the nozzle 21 through the connecting hole of the end cover 24. An elastic reset member 26 is provided between the tube walls of the outer sleeve 22 and the inner sleeve 23, and the elastic reset member 26 acts on the inner sleeve 23, and is suitable for making the inner sleeve 23 have a movement tendency close to the rear end of the outer sleeve 22. When the nozzle 21 finishes spraying, and the amount of liquid in the outer sleeve 22 is less than the set value, the inner sleeve 23 moves toward the rear end of the outer sleeve 22 under the action of the elastic reset member 26, driving the nozzle 21 to retract into the accommodating cavity of the seat ring body 10. More specifically, the elastic return member 26 is a compression spring, and the interior of the outer sleeve 22 is provided with a raised surface and a limit sleeve for mounting the compression spring, one end of the compression spring abuts against the end surface of the inner sleeve 23 close to the end cover 24, and the other end is sleeved on the limit sleeve and abuts against the raised surface.

[0044] The outer sleeve 22 is provided with a nozzle cleaning port 22c at a position close to the nozzle 21, and the nozzle cleaning port 22c is connected to the water tank 300 through a pipeline. After the flushing mechanism 20 finishes working, that is, when the nozzle 21 is located in a non-working state inside the seat ring body 10, the water in the water tank 300 is controlled by controlling the water path to allow the water in the water tank 300 to enter the inner part of the outer sleeve 22 through the nozzle cleaning port 22c of the outer sleeve 22 to flush the outer wall of the nozzle 21, thereby further improving the cleanliness of the nozzle 21.

[0045] Specifically, the arrangement of the drainage groove 22b is not unique; in one embodiment, Figure 2-Figure 5 As shown, the drainage groove 22b is arranged on the inner tube wall of the outer tube 22 close to the first opening side, and two drainage grooves 22b are arranged, which are respectively located on the upper and lower sides of the inner tube wall of the outer tube 22. In another embodiment, the drainage groove 22b is arranged on the outer tube wall of the inner tube 23. When the inner tube 23 slides outward with respect to the outer tube 22, the cleaning liquid between the inner tube 23 and the outer tube 22 can be discharged.

[0046] Specifically, the nozzle 21 is detachably connected to the inner sleeve 23, so that the user can remove and clean the nozzle 21. Specifically, the nozzle 21 includes a nozzle body 211 and a connecting sleeve 212 located at the rear side of the nozzle body 211. The nozzle body 211 is provided with a plurality of spray holes 211a. Specifically, the spray holes 211a are located on the front end surface of the nozzle body 211. The connecting sleeve 212 is detachably connected to the front end of the inner sleeve 23.

[0047] More specifically, if Figure 6 As shown, the outer wall of the inner sleeve 23 is provided with at least one snap-fitting protrusion 23a, for example, the snap-fitting protrusion 23a is formed into a cylindrical protrusion structure, and the rear end of the connecting sleeve 212 is correspondingly provided with at least one notch groove 212a, and the notch groove 212a is provided with a snap-fitting area 212b matching the shape of the snap-fitting protrusion 23a, for example, the end of the notch groove 212a is formed into a circular groove body structure that cooperates with the cylindrical protrusion, wherein the opening width of the notch groove 212a is smaller than the width of the snap-fitting area 212b.

[0048] When the connecting sleeve 212 is sleeved on the outer wall of the inner sleeve 23, the cylindrical clamping protrusion 23a deforms the connecting sleeve 212, enlarges the opening of the notch groove 212a, and finally clamps to the circular clamping area 212b. When the nozzle 21 is disassembled, the clamping protrusion 23a squeezes the groove wall of the notch groove 212a to enlarge the opening, thereby realizing the removal of the nozzle 21.

[0049] In order to facilitate the user to disassemble and assemble the nozzle 21, the nozzle body 211 is provided with convex ribs on the opposite side walls close to its front end surface; the user can hold the convex rib side to pull to remove the nozzle 21, or hold the convex rib side to push inward to install the nozzle 21 on the inner sleeve 23.

[0050] like Figure 2-Figure 4 As shown, the seat ring 100 also includes a baffle 25 pivotally connected to the front end of the outer sleeve 22. When the nozzle 21 is in a retracted state, the baffle 25 closes the opening of the seat ring body 10 to prevent the nozzle 21 from contacting the outer area of ​​the seat ring body 10; when the nozzle 21 is controlled to extend outward, the nozzle 21 acts on the baffle 25 to pivot the baffle 25 in a direction away from the opening.

[0051] Specifically, in an optional implementation, the pivot position of the baffle door 25 is located on the upper side of the center of gravity of the baffle door 25, which enables the baffle door 25 to quickly close the opening under the action of its own gravity.

[0052] The present invention also provides a specific implementation of a toilet. Figure 7As shown, the toilet has a toilet body 200, a water tank 300 located at the upper rear part of the toilet body 200, and a seat ring 100 pivotally connected to the toilet body 200, and also includes a distributor 70, the distributor 70 can be arranged inside the water tank 300, the distributor 70 is connected with the water inlet 22a and the nozzle cleaning port 22c of the flushing mechanism 20; specifically, the distributor 70 includes a first working position, a second working position and a third working position, when the distributor 70 is in the first working position, its first outlet 71 is connected with the nozzle cleaning port 22c, when the distributor 70 is in the second working position and the third working position, its second outlet 72 is connected with the water inlet 22a, wherein the flow rate of the second working position is less than the flow rate of the third working position.

[0053] In an optional implementation, the distributor 70 further includes a fourth working position, and the flow rate of the fourth working position is greater than the flow rate of the third working position.

[0054] Specifically, the first outlet 71 of the distributor 70 is connected to the nozzle cleaning port 22c of the flushing mechanism 20 through a first pipeline 51. In one specific embodiment, a flow detection device 40 is provided on the first pipeline 51. The second outlet 72 of the distributor 70 is connected to the water inlet 22a of the flushing mechanism 20 through a second pipeline 52. In one specific embodiment, a heating device 60 is provided on the second pipeline 52. In other alternative embodiments, the flow detection device 40 and the heating device 60 can also be respectively located on the water inlet pipeline of the distributor 70.

[0055] The present invention also provides a specific implementation of the control method of the above toilet, which is used to control the toilet for female flushing, and includes the following control steps:

[0056] S1. Control the distributor 70 to be in the first working position, and when the flow rate of the first pipeline 51 is greater than the first set value, control the heating device 60 to start;

[0057] Specifically, the control of the dispenser 70 may be based on the user's triggering of the control button area of ​​the toilet. For example, after the controller obtains the trigger signal of the female flush button, it starts to control the dispenser 70 to enter the first working position; Figure 8 As shown, at this time, the distributor 70 is connected to the nozzle cleaning port 22c to perform external flushing of the nozzle 21. When the flow rate of the first pipeline 51 is greater than the first set value, the cleaning liquid has entered the inner wall of the outer sleeve 22 along the nozzle cleaning port 22c to flush the outer wall of the nozzle 21. At this time, the cleaning liquid passing through the second pipeline 52 begins to be heated in preparation for warm water spraying.

[0058] S2. Control the dispenser 70 to be located at the second working position, and after maintaining the first set time, control the dispenser 70 to be located at the third working position.

[0059] While the cleaning liquid in the second pipeline 52 is being heated, the distributor 70 is controlled to be located at the second working position, such as Fig. 9 As shown, the second outlet 72 of the distributor 70 is connected to the water inlet 22a of the flushing mechanism 20. Since the flow rate of the distributor 70 is low when it is in the second working position, the water pressure entering the outer sleeve 22 of the flushing mechanism 20 is not enough to push the inner sleeve 23 to slide to the set position suitable for spraying. At this time, the water flows along the area between the outer sleeve 22 and the inner sleeve 23. Fig. 9 The cold water in the flushing mechanism 20 is basically drained after the dispenser 70 is kept in the second working position for a first set time, such as 2 seconds. At this time, the dispenser 70 is controlled to be in the third working position, such as Fig.10 As shown, since the flow rate of the distributor 70 is relatively large when it is in the third working position, the water pressure entering the outer sleeve 22 of the flushing mechanism 20 can push the inner sleeve 23 to slide to a set position suitable for spraying, and spraying can be performed at this position.

[0060] Further, in an optional embodiment, after controlling the distributor 70 to be located at the third working position and maintaining the second set time, the distributor 70 is controlled to be located at the fourth working position, and the flow rate of the fourth working position of the distributor 70 is greater than the flow rate of the third working position;

[0061] Specifically, when the dispenser 70 is located in the third working position and maintains the second set time, for example 1 second, the nozzle 21 located at the proximal end of the inner sleeve 23 is in the set spray position. At this time, the dispenser 70 is controlled to be located in the fourth working position, so that the water pressure entering the flushing mechanism 20 increases to the set value, thereby achieving flushing of the female private parts and improving flushing comfort and efficiency.

[0062] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, the obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
