For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0039] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0040] Such as Figures 1-14The following shows a specific embodiment of the seat ring 100 provided by the present utility model. Among them, the seat ring 100 has at least a cleaning function, and may also have functions such as warming and sterilization. The seat ring includes a seat ring main body 10 and a cleaning component 20 located inside it. The cleaning component 20 can be installed in the front cavity of the seat ring main body 10 to achieve cleaning of the female genital area, or can be installed in the rear cavity of the seat ring main body 10 to achieve anal cleaning, or can be installed in both the front and rear of the seat ring main body 10 at the same time. Among them, the "front end" of the cleaning component 20 and its various components of the present utility model refers to the water outlet end close to the internal water flow direction, and the "rear end" refers to the water inlet end close to the internal water flow direction.

[0041] The cleaning component 20 includes a mounting support 21, and the mounting support 21 has a guiding slideway 211 extending in a first direction; a nozzle main body 22 slidably connected to the mounting support 21 in the first direction and a driving component. Among them, the nozzle main body 22 is communicated with a water supply device, and a water spraying hole 222 is provided at the end of the nozzle main body 22; the driving component includes a driving motor and a transmission component. The transmission component includes a driving transmission member connected to the output shaft of the driving motor and a driven transmission member connected to the nozzle main body 22. The driven transmission member is slidably connected to the mounting support 21 in the first direction; the nozzle main body 22 expands and contracts in the first direction under the action of the driving component, wherein the first direction has a non-zero angle with the horizontal direction.

[0042] Figures 2-8 The following shows the first specific embodiment of the seat ring of the present utility model. Among them, as Figures 2-4 shown, the cleaning component 20 includes a mounting support 21, a nozzle main body 22 slidably connected to the mounting support 21 in a first direction ( Figure 4 the direction of arrow a in the figure), and a driving component for driving the nozzle main body 22 to move.

[0043] Among them, as Figure 5 shown, a nozzle water inlet 221 communicated with the water supply device is provided in the rear area of the nozzle main body 22, and a water spraying hole 222 is provided in the front area of the nozzle main body 22. The driving component includes a first motor 23 and a gear-rack transmission group. The gear 24 of the gear-rack transmission group is connected to the output shaft of the first motor 23, and the rack 25 of the gear-rack transmission group is fixedly connected to the nozzle main body 22 and extends in the first direction, wherein the first direction has a non-zero angle with the horizontal direction. For example, as Figure 2 , Figure 3As shown, the angle between the first direction and the horizontal direction is between 20° and 45°. When the first motor 23 rotates, the gear 24 drives the rack 25 to move, causing the nozzle body 22 to reciprocate relative to the seat ring body 10 in the first direction, realizing the extension or retraction of the nozzle body 22 relative to the seat ring body 10.

[0044] For the seat ring 100 having the above cleaning assembly 20, when performing flushing control, as Figure 3 shown, the first motor 23 can be controlled to rotate to move the nozzle body 22 to a set position outside the seat ring body 10. After the nozzle body 22 is in place, the control valve of the water supply device is opened to perform the flushing operation. The water pressure can be adjusted according to different situations, and the cleaning comfort is relatively high. At the same time, the first motor 23 can drive the nozzle body 22 to spray water while moving, and the matching degree between the cleaning area and the human body is relatively high. After the cleaning operation is completed, as Figure 2 shown, the first motor 23 is controlled to rotate to move the nozzle body 22 to the inside of the seat ring body 10 to prevent the nozzle body 22 from being contaminated.

[0045] In an alternative embodiment, as Figure 6 、 Figure 7 shown, the mounting support 21 is a receiving cavity with openings on the front and rear sides. The receiving cavity is provided with a guiding slideway 211 extending in the first direction, and the nozzle body 22 is slidably connected to the guiding slideway 211.

[0046] More specifically, in an alternative embodiment, as Figure 8 shown, the front side region of the nozzle body 22 is formed into an approximately elliptical cylinder with flat upper and lower surfaces and arc-shaped left and right surfaces; at least part of the region of the receiving cavity of the mounting support 21 matches the shape of the front side region of the nozzle body 22. The nozzle body 22 is inserted into the receiving cavity of the mounting support 21. Convex ribs extending in the first direction are provided on the upper and lower cavity walls of the receiving cavity to form the guiding slideway 211, so that the nozzle body 22 can slide relative thereto. This guiding structure can make the sliding of the nozzle body 22 more stable. In other alternative embodiments, a guiding protrusion or a guiding groove extending in the first direction is provided on the upper cavity wall of the receiving cavity of the mounting support 21, and a guiding structure matching the guiding protrusion or the guiding groove is provided on the upper wall of the rack 25. For example, a guiding groove matching the guiding protrusion and a guiding rib matching the guiding groove; when the first motor 23 is controlled to rotate, the rack 25 drives the nozzle body 22 to move in the first direction to realize extension or retraction.

[0047] Specifically, the first motor 23 is installed on the side wall of the mounting support 21 through a threaded fastening assembly, as Figure 4 、 Figure 6As shown, the side wall of the mounting support 21 is provided with a mounting hole 213, and the output shaft of the first motor 23 extends into the inner side of the mounting support 21 along the mounting hole 213. More specifically, a partial area of the gear 24 in the axial direction is located in the area where the mounting hole 213 is located, and a partial area is located in the accommodating cavity of the mounting support 21 to be meshed and connected with the rack 25. When installing the installation drive assembly, first install the nozzle body 22 fixedly connected with the rack 25 into the mounting support 21, then install the gear 24 on the output shaft of the first motor 23, extend the output shaft of the first motor 23 along the mounting hole 213 of the mounting support 21 to make the gear 24 mesh with the rack 25, and preferably install the first motor 23 on the outer surface of the mounting support 21 through fastening bolts.

[0048] Specifically, in an alternative embodiment, as Figure 6 、 Figure 7 shown, the front side of the mounting support 21 is provided with an extension hole 214, and the nozzle body 22 extends or retracts along the extension hole 214; a nozzle flushing interface 212 is provided on the side wall of the mounting support 21 close to the extension hole 214, and the nozzle flushing interface 212 is communicated with a water supply device to flush the outer wall of the nozzle body 22 when the nozzle body 22 is in a retracted state, avoiding the problem that the outer wall of the nozzle body 22 is soiled and pollutes the cleaning liquid.

[0049] Specifically, as Figure 2 、 Figure 3 shown, the front end face of the nozzle body 22 extends substantially in the vertical direction to match the extension direction of the outer wall of the seat ring body 10 in this area, so that it matches the opening surface of the seat ring body 10 when retracted, and the integrity is better. The water spraying holes 222 extend obliquely upward relative to the horizontal direction. For example, the water spraying holes 222 form an angle of 10° - 55° relative to the horizontal direction to better match the position of the human privacy part and form a better flushing effect.

[0050] Specifically, as Figure 5 shown, the nozzle water inlet 221 is located at the rearmost end of the nozzle body 22, and the extension direction of the nozzle water inlet 221 is different from the extension direction of the nozzle body 22, that is, there is an angle between the two extension directions. The nozzle water inlet 221 does not occupy the space of the seat ring in the first direction, facilitating the arrangement and installation of other structures. More specifically, the extension direction of the nozzle water inlet 221 is vertically intersecting with the extension direction of the nozzle body 22, and the nozzle water inlet 221 and the first motor 23 are respectively located on opposite sides of the mounting support 21, facilitating the installation of the first motor 23 and the connection of the nozzle water inlet 221 with the water supply water pipe.

[0051] Specifically, in an alternative embodiment, as Figure 4 、 Figure 5As shown, the mounting support 21 is made of a plastic part, and a sealing cover 219 is provided on its rear side to encapsulate the nozzle body 22 in the accommodation cavity of the mounting support 21; one end of the sealing cover 219 is pivotally connected to the first side wall of the mounting support 21, and the other end is snap-connected to the second side wall of the mounting support 21. When installing the nozzle body 22, the sealing cover 219 on the mounting support 21 is opened, and the nozzle body 22 is inserted along the rear side of the mounting support 21 until the front end face of the nozzle body 22 is flush or nearly flush with the front end face of the mounting support 21, and then the snap structure on the sealing cover 219 is snap-connected to the second side wall of the mounting support 21.

[0052] Specifically, in order to reliably install the cleaning assembly 20 inside the seat ring body 10, as Figure 4 , Figure 5 shown, at least one connecting lug 215 is provided on the mounting support 21, and the two connecting lugs 215 are respectively arranged on the left and right sides of the mounting support 21. A connecting hole for connecting with the seat ring body 10 is provided on the connecting lug 215; the installation and fixation of the cleaning assembly 20 are realized by a fastening assembly passing through the connecting hole of the connecting lug 215.

[0053] Figures 9-11 Fig. shows the second specific embodiment of the seat ring of the present invention. In this embodiment, a second motor 26 is added on the basis of the driving assembly of the first specific embodiment. The output shaft of the second motor 26 acts on the mounting support 21 to drive the mounting support 21 to swing around the output axis direction of the second motor 26. In this way, when the user performs flushing and cleaning, the first motor 23 is controlled to first extend the nozzle body 22 to a set position outside the seat ring body 10, and the second motor 26 controls the mounting support 21 to swing to expand the flushing range. Or, after the nozzle body 22 extends to the set position, the first motor 23 controls the nozzle body 22 to expand and contract along the first direction to realize the linear movement cleaning of the nozzle body 22 along the first direction, and the second motor 26 controls the mounting support 21 to drive the nozzle body 22 to swing to further realize the swing flushing of the nozzle body 22.

[0054] Specifically, the second motor 26 is fixedly connected to the seat ring body 10. A plug-in groove 216 is provided in the middle area of the mounting support 21 along the first direction. The output shaft of the second motor 26 is inserted into the plug-in groove 216 of the mounting support 21 to realize the transmission connection between the two, and the mounting support 21 drives the nozzle body 22 located therein to swing accordingly.

[0055] Specifically, in this embodiment, clamping claws are provided on the upper and lower sides of the sealing cover 219, and it is clamped on the upper and lower sides of the mounting support 21 through the clamping claws.

[0056] Figures 12-14 The third specific embodiment of the seat ring according to the present utility model is shown. In this embodiment, the cleaning assembly 20 includes a mounting support 21, and the mounting support 21 has a guiding slideway 211 extending in the first direction; a nozzle main body 22 slidably connected to the mounting support 21 in the first direction and a driving assembly. The driving assembly includes a third motor 27 and a transmission assembly formed by a turntable 28 and an elastic belt 29 wound around the turntable 28. The output shaft of the third motor 27 is connected to the turntable 28, and one end of the elastic belt 29 is connected to the nozzle main body 22. When the third motor 27 rotates in the first direction, the turntable 28 drives the elastic belt 29 to move, so that the nozzle main body 22 moves from the inside of the seat ring main body 10 to the outside of the seat ring main body 10; when the third motor 27 rotates in the second direction, the turntable 28 drives the elastic belt 29, so that the nozzle main body 22 moves from the outside of the seat ring main body 10 to the inside of the seat ring main body 10.

[0057] For the seat ring 100 with the above cleaning assembly 20, when controlling the flushing, the nozzle main body 22 can be moved to a set position outside the seat ring main body 10 by controlling the rotation of the third motor 27, and the position accuracy is relatively high; after the nozzle main body 22 reaches the position, the waterway switch is turned on to perform the flushing operation, and the water pressure can be adjusted according to different situations, and the flushing comfort is relatively high. At the same time, the third motor 27 can also drive the nozzle main body 22 to spray water while moving, and the matching degree between the cleaning area and the human body is relatively high.

[0058] Specifically, the nozzle main body 22 is slidably connected to the guiding slideway 211 through a slider 223. The slider 223 moves along the guiding slideway 211 under the driving force of the elastic belt 29, realizing the extension and retraction of the nozzle main body 22.

[0059] Specifically, the end of the elastic belt 29 is connected to the slider 223. Specifically, the elastic belt 29 has a socket, and the slider 223 has a plugging protrusion, and the plugging protrusion of the slider 223 is plugged into the socket of the elastic belt 29.

[0060] Specifically, in an alternative embodiment, the slider 223 is integrally connected to the rear end of the nozzle main body 22.

The cross section of the slider 223 is in the form of a dovetail groove, and it is sleeved outside the guiding slideway 211.

[0061] Specifically, the elastic band 29 is a bendable and rigid metal band, such as a steel band; the elastic band 29 has a first position and a second position driven by the turntable 28. When the elastic band 29 is in the first position, the nozzle body 22 is in the initial position inside the seat ring body 10; when the elastic band 29 is in the second position, the nozzle body 22 extends out of the seat ring body 10, that is, the nozzle body 22 is in the flushing position. As Figure 4 , Figure 6 shown, the bending area of the elastic band 29 when in the first position is larger than the bending area of the elastic band 29 when in the second position.

[0062] The mounting support 21 is also provided with a limiting track 217, and the limiting track 217 extends along a curve and surrounds the outer area of the turntable 28 to limit the position of the elastic band 29; specifically, when the elastic band 29 is in the first position, most of the area of the elastic band 29 is inside the limiting track 217 of the mounting support 21, and when the elastic band 29 is in the second position, the front end area of the elastic band 29 moves forward with the slider 223, and part of its area is outside the limiting track 217 and extends along a straight line, and part of the area is inside the limiting track 217.

[0063] Specifically, in order to reliably install the cleaning assembly 20 inside the seat ring body 10, the mounting support 21 is provided with connecting lugs 215, and the connecting lugs 215 are provided with connecting holes for connecting with the seat ring body 10; the installation and fixation of the cleaning assembly 20 are realized by a fastening assembly passing through the connecting holes of the connecting lugs 215.

The seat ring 100 adopts the structure described above and will not be elaborated here.

[0065] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present utility model.
