Description

Technical Field

[0001] The invention relates to the technical field of bathroom equipment, in particular to a seat ring assembly of a toilet. Background Art

[0002] Existing smart toilets are generally equipped with a seat sensing device for detecting the seat ring. A micro switch connected to a seat detection circuit is usually provided in the rear shell on the seat body to detect whether someone is sitting. A fixing frame is installed in the rear shell, and a movable part cooperating with the micro switch is slidably provided on the fixing frame. The rear end of the seat ring is rotatably connected to the rear shell through a rotating shaft. An axial hole is provided in the side wall of the rear shell. The rotating shaft at the rear end of the seat ring moves through the axial hole and extends into the rear shell to cooperate with the movable part. An elastic part that provides an upward elastic force to the movable part is provided between the movable part and the fixing frame. The elastic part also causes the rear end of the rotating shaft and the seat ring to be lifted upward when the seat is not seated, and causes the movable part to press the button of the micro switch. When the seat ring is in a closed state (i.e., the front end of the seat ring falls onto the seat body) and someone sits down, the seat ring is pressed downward, and the rotating shaft at the rear end of the seat ring presses down on the movable part arranged inside the rear shell, the movable part disengages from the button of the microswitch, the button of the microswitch pops up, the microswitch is turned on, and the detection signal collected by the seat detection circuit changes, based on this, it is judged that someone is sitting down; when the human body leaves the seat, the movable part pops up and resets to the initial state under the action of the elastic part, the movable part drives the rotating shaft to move upward and reset, so that the rear end of the seat ring is lifted upward, and at the same time, the button of the microswitch is pressed by the movable part again, the microswitch is turned off, and the detection signal collected by the seat detection circuit changes, based on this, it is detected that the human body has left the seat.

[0003] However, in the existing structure, when the seat is flipped upward, the seat is pressed downward by its own gravity or external force. The rotating shaft at the rear end of the seat will also press the movable parts in the rear shell, causing the micro switch to malfunction. The seat detection circuit will mistakenly detect that a human body is sitting, thereby mistakenly activating related functions of the smart toilet. Summary of the invention

[0029] The rotating shaft of the present invention has a semi-shaft section, and the semi-shaft section has an arc surface side and a notch side that match the movable part. When the seat ring is in the closed position, at least a part of the arc surface side of the semi-shaft section faces downward. When the rotating shaft moves from the lifting position to the falling position under the action of external force, the arc surface side presses the movable part to drive the movable part to move, thereby causing the movable part to press the switch or release the pressure on the switch, thereby turning on or off the switch, and being able to reliably detect whether someone sits down; when the seat ring is in the flipping position, the notch side of the semi-shaft section faces downward, and the rotating shaft is limited by the shell or the fixed frame when it moves from the lifting position to the falling position under the weight of the seat ring or the action of external force, so that the notch side is kept separated from the movable part, so as to avoid the rotating shaft pressing the movable part downward when the seat ring is pressed downward due to the weight of the seat ring itself or the action of external force on the seat ring, thereby avoiding the switch malfunctioning and malfunctioning to open the relevant functions of the toilet bowl;

[0030] Alternatively, the rotating shaft of the present invention has a half-shaft section, which has an arc surface side and a notch side that cooperate with the switch. When the seat ring is in the closed position, at least a portion of the arc surface side faces downward, and when the rotating shaft moves from the raised position to the lowered position under the action of an external force, the arc surface side presses the switch, thereby turning on or off the switch, and can reliably detect whether someone is sitting down; when the seat ring is in the flipped position, the notch side faces downward, and when the rotating shaft moves from the raised position to the lowered position under the weight of the seat ring or the action of an external force, it is limited by the shell body, so that the notch side remains separated from the switch, thereby preventing the rotating shaft from pressing the switch when the seat ring is pressed downward due to the seat ring's own gravity or external force, thereby preventing the switch from malfunctioning and erroneously turning on the relevant functions of the toilet.

DETAILED DESCRIPTION

[0045] Embodiment 1

[0046] See also Figures 1 to 11 As shown, a toilet seat assembly of this embodiment includes:

[0047] A housing 1, which is fixed to a toilet seat (not shown);

[0048] A fixing frame 2, which is fixed in the housing 1;

[0049] A switch 3 is mounted on the fixing frame 2 and is connected to a seat detection circuit (not shown in the figure) of the toilet;

[0050] A movable member 4 is movably arranged on the fixed frame 2 and cooperates with the switch 3;

[0051] The seat ring 6, whose rear end is rotatably arranged on the housing 1 via the rotating shaft 7, can rotate between the raised position and the closed position relative to the housing 1, a shaft hole 11 is provided on the side wall of the housing 1, the rotating shaft 7 includes a semi-shaft section 71 protruding from the seat ring 6, the semi-shaft section 71 movably passes through the shaft hole 11 and extends into the housing 1, the housing 1 supports the seat ring 6 via the semi-shaft section 71, the semi-shaft section 71 has an arc surface side 711 and a notch side 712 matched with the movable member 4, and the rotating shaft 7 can slide up and down in the shaft hole 11 relative to the housing 1 between the raised position and the dropped position;

[0052] When the seat ring 6 is in the closed position, at least a part of the arc surface side 711 faces downward, and when the rotating shaft 7 slides downward from the raised position to the dropped position under the action of external force, the arc surface side 711 presses the movable member 4 to drive the movable member 4 to move, thereby causing the movable member 4 to release the pressure on the switch 3, thereby turning on or off the switch 3, and the rotating shaft 7 and the movable member 4 can be reset after the external force is removed;

[0053] When the seat ring 6 is in the flipped-up position, the notch side 712 faces downward, and the semi-shaft section 71 of the rotating shaft 7 is limited by the shell 1 when it slides from the raised position to the dropped position under the weight of the seat ring or external force, so that the notch side 712 remains separated from the movable part 4, that is, the rotating shaft 7 remains separated from the movable part 4, and the switch 3 remains in the disconnected or connected state.

[0054] The toilet seat can judge whether someone is sitting on it by setting it to be someone sitting on it when the switch 3 is turned on, or someone sitting on it when the switch 3 is turned off, and the specific design is carried out according to needs.

[0055] See also Figures 2 to 9 As shown, in this embodiment, the seat ring assembly further includes a first elastic member 5 disposed in the housing 1 for providing an upward elastic force to the movable member 4. After the external force acting on the rotating shaft 7 is removed, the movable member 4 can be reset under the action of the first elastic member 5 and drive the rotating shaft 7 to reset to the raised position; the first elastic member 5 is specifically a compression spring disposed between the movable member 4 and the fixing frame 2. Of course, in other embodiments, the first elastic member can also be a compression spring disposed between the movable member 4 and the housing 1.

[0056] Specifically, in this embodiment, the fixing frame 2, the switch 3, the movable member 4 and the first elastic member 5 are substantially arranged at Figure 1Inside the shell 1 at A in the middle, the fixed frame 2 and the shell 1 are formed separately, and the movable part 4 can be slidably arranged on the fixed frame 2 up and down. The switch 3 is connected to the seat detection circuit (not shown in the figure) in the shell 1. The movable part 4 is specifically matched with the button of the switch 3 (not marked in the figure). The switch 3 is specifically arranged above the movable part 4. The switch 3 is a normally closed micro switch. When the seat ring 6 is in the closed position, a part of the arc side 711 faces downward. When the rotating shaft 7 slides from the raised position to the fallen position under the action of external force, the arc side 711 presses the movable part 4 to drive the movable part 4 to slide downward, thereby releasing the pressure on the button of the switch 3 by the movable part 4, thereby turning on the switch 3. Of course, in other embodiments, the fixing frame 2 may be integrally formed with the shell 1; the movable part 4 may be swingably disposed on the fixing frame 2, and when the rotating shaft 7 slides from the raised position to the dropped position under the action of an external force, the arcuate side 711 presses against the movable part 4 to drive the movable part 4 to swing so that the movable part 4 releases the pressure on the button of the switch 3; the switch 3 may also be a normally open micro switch, and when the seat ring 6 is in the closed position, a part of the arcuate side 711 faces downward, and when the rotating shaft 7 slides from the raised position to the dropped position under the action of an external force, the arcuate side 711 presses against the movable part 4 to drive the movable part 4 to slide downward so that the movable part 4 releases the pressure on the button of the switch 3, thereby disconnecting the switch 3.

[0057] See also Figure 4 , Figures 6 to 8 As shown, in this embodiment, the semi-shaft segment 71 is a solid structure, so that the strength of the semi-shaft segment 71 is reliable; the notch side 712 is a straight surface, of course, it can also be a curved surface; the curved surface side 711 is a circular arc surface, and the curvature of the circular arc surface is greater than 180°, so that the strength of the semi-shaft segment 71 is more reliable. When the notch side 712 adopts a curved surface, the curvature of the notch side 712 needs to be greater than the curvature of the curved surface side 711, so as to form a notch-shaped shaft instead of a circular shaft.

[0058] See also Figure 7 As shown, in this embodiment, when the seat ring 6 is in the flipped position and the rotating shaft 7 slides from the raised position to the dropped position, the half shaft section 71 is limited by the hole wall at the lower part of the shaft hole 11, so that the notch side 712 remains separated from the switch 3.

[0059] See also Figure 7 and Fig. 9As shown, in this embodiment, the shaft hole 11 is a runway-shaped through hole, and the length direction of the runway-shaped through hole is longitudinally arranged. When the seat ring 6 is in the raised position and the rotating shaft 7 moves from the raised position to the dropped position, the semi-shaft segment 71 is limited by the hole wall at the lower part of the shaft hole 11, specifically, the two side edges of the notch side 712 are limited by the hole wall at the lower part of the shaft hole 11, so that the notch side 712 is kept separated from the movable part 4. Of course, the shaft hole 11 can also be a through hole of other shapes, as long as it can achieve the effect of allowing the semi-shaft segment 71 to move up and down in the shaft hole 11 so that the rotating shaft 7 can move up and down between the raised position and the dropped position, and when the seat ring 6 is in the raised position and the rotating shaft 7 slides to the dropped position, the semi-shaft segment 71 can be limited by the hole wall at the lower part of the shaft hole 11 so that the notch side 712 is kept separated from the movable part 4.

[0060] See also Figure 2 and Figure 7 As shown, in this embodiment, the fixed frame 2 has a cavity 21, the movable member 4 can be slidably arranged in the cavity 21, the switch 3 is located outside the cavity 21, the cavity 21 has a clearance hole 22 and an opening 23 corresponding to the shaft hole 11, the semi-axial segment 71 passes through the shaft hole 11 and the opening 23 in sequence and then extends into the cavity 21 to cooperate with the movable member 4, the movable member 4 is provided with a pressing portion 41, the pressing portion 41 passes through the clearance hole 22 and cooperates with the switch 3, a first sealing ring 8 is provided between the hole edge of the clearance hole 22 and the pressing portion 41, and the inner circumference of the first sealing ring 8 is kept in sealing cooperation with the pressing portion 41 when the movable member 4 moves; a second sealing ring 9 is provided between the fixed frame 2 and the housing 1, and the second sealing ring 9 is arranged around the outer circumference of the opening 23 to make the shaft hole 11 and the opening 23 sealed and connected; the material of the first sealing ring 8 and the second sealing ring 9 are both rubber material or other elastic material. The fixing frame 2 in this embodiment has a cavity 21, and the cavity 21 has a clearance hole 22 for the pressing portion 41 to move through and an opening 23 corresponding to the shaft hole 11. By arranging a first sealing ring 8 between the hole wall of the clearance hole 22 and the pressing portion 41, the inner periphery of the first sealing ring 8 is kept in sealing cooperation with the pressing portion 41 when the movable part 4 moves, and a second sealing ring 9 is arranged between the fixing frame 2 and the shell 1, and the second sealing ring 9 is arranged around the outer periphery of the opening 23, so that when cleaning the toilet, the cleaning water flow entering the shell 1 through the shaft hole 11 can be blocked between the cavity 21 of the fixing frame 2 and the shell 1, so as to prevent the cleaning water flow from flowing into the switch 3 in the shell 1 through the shaft hole 11, thereby avoiding the switch 3 being used in a humid environment for a long time and affecting the service life, thereby improving the waterproof performance of the product and making the quality more stable and reliable.

[0061] See also Figure 2 , Figure 3 and Figure 5As shown, in this embodiment, the clearance hole 22 is provided on the side wall of the cavity 21, the first sealing ring 8 is tapered, the large opening end of the first sealing ring 8 is sealed with the edge of the clearance hole 22, and the small opening end of the first sealing ring 8 is sealed with the outer wall of the pressing portion 41. In this embodiment, the first sealing ring 8 is set to be tapered, so that the first sealing ring 8 has a large deformation capacity, which can not only allow the pressing portion 41 to slide up and down with the movable part 4 within a certain range, but also make the small opening end of the first sealing ring 8 reliably seal with the outer wall of the pressing portion 41 to ensure the sealing effect, and can also avoid the pressing portion 41 from excessively squeezing the first sealing ring 8 to cause fatigue failure of the first sealing ring 8, thereby extending the service life of the first sealing ring 8. Specifically, in this embodiment, the large open end of the first sealing ring 8 is folded outward to form an annular groove 81, and the circumference of the clearance hole 22 has an annular clamping portion 24 that can be clamped and matched with the annular groove 81. The first sealing ring 8 is installed on the fixing frame 2 through the clamping fit between the annular clamping portion 24 and the annular groove 81, and the large open end of the first sealing ring 8 is sealed with the edge of the hole of the clearance hole 22.

[0062] See also Figures 2 to 9 As shown, in this embodiment, it also includes a gland 10 installed on the fixing frame 2, and the switch 3 is fixed between the fixing frame 2 and the gland 10 through the gland 10. The gland 10 presses the large opening end of the first sealing ring 8 against the annular clamping portion 24, so that the first sealing ring 8 is more reliably installed on the fixing frame 2 to ensure the sealing effect.

[0063] See also Figure 2 , Figure 5 and Fig.10 As shown, in this embodiment, the rotating shaft 7 also includes a connecting section 72 connecting the seat ring 6 and the semi-shaft section 71. The semi-shaft section 71 and the connecting section 72 are integrally formed, and the connecting section 72 is detachably fixedly connected to the seat ring 6, so that when the rotating shaft 7 is damaged, only the rotating shaft 7 needs to be replaced, and the seat ring 6 does not need to be replaced, thereby reducing maintenance costs. Of course, in other embodiments, the semi-shaft section 71 and the seat ring 6 may also be an integrated structure.

[0064] In this embodiment, the material of the rotating shaft 7 is a composite modified material of PA66 and glass fiber, which has good strength and is more wear-resistant, and can extend the service life of the rotating shaft 7.

[0065] The working principle of this embodiment is briefly described as follows:

[0066] See also Figures 2 to 4As shown, when the seat ring 6 rotates to the closed position, the rotating shaft 7 rotates with the seat ring 6 to a part of the arc surface side 711 facing downward and abutting against the movable member 4. In the initial state, under the action of the first elastic member 5, the pressing portion 41 of the movable member 4 presses the button of the switch 3, and the switch 3 is in the off state. At this time, the movable member is supported by the first elastic member 5, and the semi-shaft segment 71 is supported by the movable member 4, that is, the housing 1 supports the semi-shaft segment 71 through the fixed frame 2, the first elastic member 5 and the movable member 4 in sequence, and then indirectly supports the rear end of the seat ring 6 through the semi-shaft segment 71. When a person sits down, the seat ring 6 is pressed downward, and the rotating shaft 7 at the rear end of the seat ring 6 slides from the raised position to the lowered position under the action of the body's weight, and the arc side 711 of the rotating shaft 7 presses the movable member 4 to drive the movable member 4 to slide downward, thereby releasing the pressure on the button of the switch 3, and the button of the switch 3 pops up, thereby turning on the switch 3, and the detection signal collected by the seat detection circuit changes, thereby judging that someone is sitting down; when a person leaves the seat, the movable member 4 pops up and resets to the initial state under the action of the first elastic member 5, and drives the rotating shaft 7 to slide upward and reset to the raised position, so that the rear end of the seat ring 6 is lifted upward, and at the same time, the button of the switch 3 is pressed again by the pressing portion 41 of the movable member 4, thereby turning off the switch 3, and the detection signal collected by the seat detection circuit changes, thereby detecting that the person leaves the seat, thereby being able to reliably detect whether someone is sitting down;

[0067] See also Figures 5 to 7 As shown, when the seat ring 6 is in the flipped-up position, the rotating shaft 7 rotates with the seat ring 6 until the notch side 712 faces downward and the notch side 712 is separated from the movable part 4. When the seat ring 6 moves downward due to its own gravity or an external force acts on the seat ring 6 to press the seat ring 6 downward to cause the rotating shaft 7 to slide from the raised position to the dropped position, the semi-axial section 71 of the rotating shaft 7 is limited by the hole wall at the lower part of the shaft hole 11, so that the notch side 712 is always kept separated from the movable part 4, so that the rotating shaft 7 cannot press the movable part 4, and the pressing part 41 of the movable part 4 always presses the switch 3, thereby avoiding the switch 3 from malfunctioning and malfunctioning to turn on the relevant functions of the toilet. At this time, the hole wall at the lower part of the shaft hole 11 supports the semi-axial section 71, that is, the shell 1 supports the rear end of the seat ring 6 through the semi-axial section 71.

[0068] In other embodiments, when the seat ring is in the flipped position and the rotating shaft slides from the raised position to the dropped position, the half-shaft section is limited by the fixed frame so that the notch side is kept separated from the movable part, which can also achieve the purpose of the present invention.

[0069] In other embodiments, when the seat ring is in the closed position, at least a portion of the arc surface side faces downward, and when the rotating shaft slides from the raised position to the dropped position under the action of external force, the arc surface side presses the movable part to drive the movable part to slide downward so that the movable part presses the switch button, thereby connecting or disconnecting the switch. Similarly, the switch can be a normally closed micro switch or a normally open micro switch. When the switch is a normally closed micro switch, the movable part presses the switch button to disconnect the switch, and when the switch is a normally open micro switch, the movable part presses the switch button to connect the switch. In short, when the seat ring is in the closed state, when the rotating shaft slides from the raised position to the dropped position, it drives the movable part to press the switch or releases the pressure on the switch, thereby connecting or disconnecting the switch, which can be selected according to needs.

[0070] In other embodiments, the rotating shaft can be reset to the raised position and drive the movable part to reset under the action of the first elastic member, and the first elastic member is specifically a compression spring disposed between the rotating shaft and the shell or the fixed frame; or, the first elastic member is provided with two for respectively resetting the movable part and the rotating shaft, one of the elastic members is a compression spring disposed between the movable part and the fixed frame or the shell, and the other elastic member is a compression spring disposed between the rotating shaft and the shell or the fixed frame.

[0076] When the seat ring is in the closed position, at least a part of the arc surface side faces downward, and when the rotating shaft slides downward from the raised position to the dropped position under the action of external force, the arc surface side presses the switch button, thereby turning on or off the switch, and can reliably detect whether someone is sitting down. The rotating shaft can be reset to the raised position after the external force is removed;

[0077] When the seat ring is in the flipped-up position, the notch side faces downward, and the semi-shaft section of the rotating shaft is limited by the shell when it slides downward from the raised position to the dropped position under the weight of the seat ring or external force, so that the notch side and the switch remain separated, that is, the rotating shaft and the switch remain separated, and then the switch remains in an off or on state, avoiding the rotating shaft from pressing the switch when the seat ring is pressed down due to the seat ring's own gravity or external force, thereby avoiding malfunction of the switch and erroneous activation of related functions of the toilet.

[0078] In this embodiment, the seat ring assembly also includes a second elastic member arranged in the shell for providing an upward elastic force to the rotating shaft. The second elastic member is arranged between the rotating shaft and the shell. After the external force acting on the rotating shaft is removed, the rotating shaft can be restored to the lifted position under the action of the second elastic member.

[0079] Specifically, in this embodiment, the switch is specifically arranged below the rotating shaft, and the switch is a normally closed micro switch. When the seat ring is in the closed position, at least a portion of the arc surface side faces downward, and when the rotating shaft slides downward from the raised position to the dropped position under the action of an external force, the arc surface side presses the switch button, thereby disconnecting the switch. Of course, in other embodiments, the switch may also be a normally open micro switch. When the seat ring is in the closed position, at least a portion of the arc surface side faces downward, and when the rotating shaft slides downward from the raised position to the dropped position under the action of an external force, the arc surface side presses the switch button, thereby connecting the switch.

[0080] In this embodiment, the semi-shaft section is a solid structure, so that the strength of the semi-shaft section is reliable; the notch side is a straight surface or an arc surface; the arc surface side is a circular arc surface, and the arc of the circular arc surface is greater than 180°, so that the strength of the semi-shaft section is more reliable. When the notch side 712 adopts an arc surface, the arc of the notch side 712 needs to be greater than the arc of the arc surface side 711, so as to form a notch-shaped shaft instead of a circular shaft.

[0081] In this embodiment, when the seat ring is located at the flipped position and the rotating shaft slides from the lifted position to the dropped position, the half shaft section is limited by the housing so that the notch side remains separated from the switch.

[0082] In this embodiment, the shaft hole is a runway-shaped through hole, and the length direction of the runway-shaped through hole is longitudinally arranged. When the seat ring is in the flipped position and the rotating shaft moves from the lifted position to the dropped position, the half shaft section is limited by the hole wall at the lower part of the shaft hole, specifically, the two side edges of the notch side are limited by the hole wall at the lower part of the shaft hole, so that the notch side is kept separated from the switch. Of course, the shaft hole can also be a through hole of other shapes, as long as it can achieve the effect of allowing the half shaft section to move up and down in the shaft hole so that the rotating shaft can move up and down between the lifted position and the dropped position, and when the seat ring is in the flipped position and the rotating shaft slides to the dropped position, the half shaft section can be limited by the hole wall at the lower part of the shaft hole so that the notch side is kept separated from the switch.

[0083] In this embodiment, the shaft further includes a connecting section connecting the seat ring and the half-shaft section, the half-shaft section and the connecting section are integrally formed, and the connecting section is detachably fixedly connected to the seat ring, so that when the shaft is damaged, only the shaft needs to be replaced without replacing the seat ring, thereby reducing maintenance costs. Of course, in other embodiments, the half-shaft section and the seat ring may also be an integrated structure.

[0084] From the above description of the present invention, it can be known that compared with the prior art, the rotating shaft of the present invention has a semi-shaft section, and the semi-shaft section has an arc surface side and a notch side that cooperate with the movable part. When the seat ring is in the closed position, at least a part of the arc surface side of the semi-shaft section faces downward. When the rotating shaft moves from the lifting position to the falling position under the action of external force, the arc surface side presses the movable part to drive the movable part to move, thereby causing the movable part to press the switch or release the pressure on the switch, thereby turning on or off the switch, and being able to reliably detect whether someone is sitting down; when the seat ring is in the flipped position, the notch side of the semi-shaft section faces downward, and the rotating shaft is limited by the shell or the fixed frame when it moves from the lifting position to the falling position under the weight of the seat ring or the action of external force, so that the notch side is kept separated from the movable part, so as to avoid the rotating shaft pressing the movable part downward when the seat ring is pressed downward due to the weight of the seat ring itself or the action of external force on the seat ring, thereby avoiding the switch from malfunctioning and malfunctioning to open the relevant functions of the toilet bowl;

[0085] Alternatively, the rotating shaft of the present invention has a half-shaft section, which has an arc surface side and a notch side that cooperate with the switch. When the seat ring is in the closed position, at least a portion of the arc surface side faces downward, and when the rotating shaft moves from the raised position to the lowered position under the action of an external force, the arc surface side presses the switch, thereby turning on or off the switch, and can reliably detect whether someone is sitting down; when the seat ring is in the flipped position, the notch side faces downward, and when the rotating shaft moves from the raised position to the lowered position under the weight of the seat ring or the action of an external force, it is limited by the shell body, so that the notch side remains separated from the switch, thereby preventing the rotating shaft from pressing the switch when the seat ring is pressed downward due to the seat ring's own gravity or external force, thereby preventing the switch from malfunctioning and erroneously turning on the relevant functions of the toilet.

[0086] The above embodiments are only used to further illustrate a toilet seat assembly of the present invention, but the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention fall within the protection scope of the technical solution of the present invention.
