Description

Technical Field

[0001] This utility model relates to the field of bathroom toilet technology, and in particular to a water valve control mechanism, a seat ring mounting box device, and a toilet. Background Technology

[0002] In the current technology, toilets are becoming more and more functional. Some toilets are equipped with a rear nozzle, also known as a pre-flushing nozzle, which is used to flush the walls of the toilet bowl to reduce the adhesion of dirt to the ceramic wall, which helps to keep the toilet bowl clean and makes it easier to clean the toilet.

[0003] In the existing technology, the rear nozzle is controlled in the following two ways:

[0004] The first method involves using a control panel or remote control. Before sitting on the seat, the user selects the corresponding button to activate the nozzle, using the pre-rinse function to rinse and wet the ceramic surface for a few seconds. However, this method increases the user's steps and is not conducive to improving the user experience. If the user is in a hurry to use the toilet, there may not be time to use the pre-rinse function.

[0005] The second method involves installing a water valve at the front end of the rear nozzle, which is opened by rotating the seat ring to supply water to the rear nozzle.

[0006] However, this method has the drawback of the rear nozzles accidentally opening: if a child flips the seat over for fun, the water valve will open and the rear nozzles will start spraying water; if the user flips the seat over while cleaning the bottom of the seat, the water valve will open and the rear nozzles will start spraying water.

[0007] In view of this, it is necessary to provide a new type of water valve control mechanism, seat mounting box device and toilet. Utility Model Content

[0008] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a water valve control mechanism, a seat ring mounting box device and a toilet. The water valve is controlled by the lifting and lowering of the seat ring through a mechanical control module. The user does not need to control the nozzle switch. The water valve will only open when the seat ring is subjected to a certain downward pressure or when it is lifted by the reset driving force of the first elastic element. This overcomes the defect of the prior art where the nozzle is accidentally opened due to the rotation of the seat ring.

[0050] The inner side of the second extension arm is provided with the seat ring pivot, which passes through the second vertical adjustment hole and can slide up and down relative to the second vertical adjustment hole.

[0051] The above technical solution has the following beneficial effects:

[0052] The water valve control mechanism, seat ring mounting box device, and toilet provided by this utility model have a mechanical control module in which the seat ring connecting shaft moves up and down along with the seat ring, thereby driving the sliding rod to move up and down synchronously. The linear movement of the sliding rod is converted into the rotation of the spindle by the swing transmission component, which in turn drives the outlet plug to rotate in both directions, so that the notch of the plug can switch between the on and off states with the eccentric outlet. Finally, the water valve is controlled to open and close as the seat ring rises and falls, thereby controlling the nozzle to spray water.

[0053] When the toilet seat is not in use, the seat connecting shaft is in its highest position and the water valve is closed. When someone sits on the seat, the seat connecting shaft is in its lowest position, and the water valve remains closed. The water valve only opens and the nozzle sprays water when the seat connecting shaft changes between the highest and lowest positions. Specifically, the nozzle sprays water for the first time when the user sits on the seat for a pre-flushing function. When the user leaves the seat, the toilet bowl walls have already been flushed, and the nozzle sprays water a second time to prolong the wetting time of the toilet bowl walls.

[0054] In summary, the water valve control mechanism, seat mounting box device, and toilet provided by this utility model control the opening and closing of the water valve by the lifting and lowering of the seat ring through a mechanical control module. Users do not need to control the opening and closing of the nozzle separately. The water valve will only open when the seat ring is subjected to a certain downward pressure and falls or is lifted by the reset driving force of the first elastic element. This overcomes the defect of the prior art where the nozzle is accidentally opened due to the rotation of the seat ring. Attached Figure Description

[0076] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0077] like Figure 1-10 As shown, an embodiment of the present invention provides a water valve control mechanism 100, characterized in that it includes a water valve 1 and a mechanical control module 2 for controlling the opening and closing of the water valve 1.

[0078] The water valve 1 includes a housing 1 having an eccentric outlet 112, an inlet pipe 12 connected to the housing 1, an outlet pipe 13 connected to the eccentric outlet 112, an outlet plug 14 pivotally mounted in the housing 1, and a rotating spindle 15 connected to the outlet plug 14.

[0079] The outlet plug 14 is provided with a plug notch 141 that can be connected to and disconnected from the eccentric outlet 112.

[0080] The mechanical control module 2 includes a vertically arranged sliding rod 21, a seat ring connecting shaft 22 arranged at the upper end of the sliding rod 21, and a first elastic element 23 for driving the sliding rod 21 to return to its original position.

[0081] A swing transmission assembly 24 for driving the rotating spindle 15 to rotate in both directions is connected between the sliding rod 21 and the rotating spindle 15.

[0082] Specifically, when the seat ring connecting shaft 22 is in its highest and lowest positions, the plug notch 141 and the eccentric outlet 112 are disconnected. When the seat ring connecting shaft 22 is in the intermediate position between its highest and lowest positions, the plug notch 141 and the eccentric outlet 112 are connected.

[0083] The water valve control mechanism provided by this utility model is used to cooperate with the seat ring 302 to control the opening and closing of the water valve 1 as the seat ring 302 rises and falls, thereby controlling the nozzle 202 to spray water and realize the pre-flushing function of the toilet bowl 3011.

[0084] The water valve control mechanism includes a water valve 1 and a mechanical control module 2, which is used to control the opening and closing of the water valve 1.

[0085] The water valve 1 includes a housing 11, an inlet pipe 12, an outlet pipe 13, an outlet plug 14, and a rotating spindle 15, etc.

[0086] The housing 11 has a water cavity, and one end of the housing 11 has an end cap 111 with an eccentric water outlet 112. The eccentric water outlet 112 is located on one side of the axis of the housing 11 / end cap 111 or on one side of the rotating spindle 15. The rotating spindle 15 can be regarded as the central axis of the housing 11 / end cap 111.

[0087] The water inlet pipe 12 is connected to one side of the housing 11 and is used to supply water to the water chamber.

[0088] The water outlet pipe 13 is connected to the end cap 111 and to the eccentric water outlet 112, which is used to drain water from the water chamber. In use, the water outlet pipe 13 is connected to the nozzle 202 via a water pipe to supply water to the nozzle 202. When the eccentric water outlet 112 is closed, the water valve 1 is closed, stopping the supply of water to the nozzle 202; when the eccentric water outlet 112 is opened, the water valve 1 is opened, and the supply of water to the nozzle 202 begins.

[0089] The outlet plug 14 is fitted inside the end cap 111 and is used to block or close the eccentric outlet 112. The outlet plug 14 has a plug notch 141, which is similar in shape to the eccentric outlet 112 and approximately equidistant from the central axis. When the outlet plug 14 is rotated, causing the plug notch 141 to connect with the eccentric outlet 112, the eccentric outlet 112 is in the open state. When the outlet plug 14 is rotated, causing the plug notch 141 to completely move away from the eccentric outlet 112, the eccentric outlet 112 is covered by the outlet plug 14, and the eccentric outlet 112 is in the closed state.

[0090] The rotating spindle 15 is arranged along the axial direction of the housing 11, with one end connected to the outlet plug 14 and the other end extending out of the housing 11 to connect with the swing transmission assembly 24. To achieve a seal, a sealing ring 156 can be fitted onto the rotating spindle 15 to seal against the wall of the water chamber. The inlet of the inlet pipe 12 is located between the outlet plug 14 and the sealing ring 156.

[0091] On the one hand, the rotating spindle 15 is used to press the outlet plug 14 onto the end cap 111; on the other hand, the rotating spindle 15 is used to connect with the mechanical control module 2 to drive the outlet plug 14 to rotate, so that the plug notch 141 can be connected and disconnected from the eccentric outlet 112, thereby controlling the opening and closing of the water valve 1.

[0092] The mechanical control module 2 includes a sliding rod 21, a seat ring connecting shaft 22, a first elastic element 23, and a swing transmission assembly 24, etc.

[0093] The sliding rod 21 is arranged vertically, perpendicular to the rotating spindle 15, and offset from the rotating spindle 15.

[0094] The seat ring connecting shaft 22 is located at the upper end of the sliding rod 21. The seat ring connecting shaft 22 is used to connect to the seat ring 302, serving as a pivot for the seat ring 302. The seat ring connecting shaft 22 can be detachably assembled with the upper end of the sliding rod 21. The seat ring connecting shaft 22 can also rest on or rest on the upper end of the sliding rod 21. Due to the action of the first elastic element 23, the upper end of the sliding rod 21 remains pressed against the bottom surface of the seat ring connecting shaft 22. The surface of the seat ring connecting shaft 22 that mates with the sliding rod 21 can be set as a plane.

[0095] The first elastic element 23, which can be a spring, elastic sheet, etc., is connected between the sliding rod 21 and the fixed structure to drive the sliding rod 21 to return to its original position. In the initial state, that is, when there is no downward pressure on the seat ring 302, the sliding rod 21 returns to its highest position under the action of the first elastic element 23, at which time the seat ring connecting shaft 22 is also at its highest position. When a user uses the seat ring 302, it will provide downward pressure to the seat ring 302, causing the seat ring connecting shaft 22 to move down to its lowest position. At this time, the sliding rod 21 is pressed down to its lowest position, and the first elastic element 23 is compressed and stores energy. The highest and lowest positions of the seat ring connecting shaft 22 can be limited by the first vertical adjustment hole 2014 on the mounting box 201, or by other limiting structures.

[0096] The swing transmission assembly 24 is connected between the sliding rod 21 and the rotating spindle 15. The swing transmission assembly 24 is used to convert the up-and-down linear motion of the sliding rod 21 into the forward and reverse rotation of the rotating spindle 15.

[0097] When the sliding rod 21 moves downward, the swing transmission assembly 24 drives the rotating spindle 15 to rotate in the forward direction. When the sliding rod 21 moves upward, the swing transmission assembly 24 drives the rotating spindle 15 to rotate in the reverse direction.

[0098] The swing transmission assembly 24 can be a structure that can convert linear motion into circular motion, such as a rocker arm assembly or a gear assembly.

[0099] The forward and reverse rotation of the spindle 15 will also drive the outlet plug 14 to rotate in both directions, thereby enabling the plug notch 141 to connect and disconnect with the eccentric outlet 112.

[0100] When the seat ring connecting shaft 22 is in its highest and lowest positions, the plug notch 141 is offset from the eccentric water outlet 112, and the eccentric water outlet 112 is covered by the outlet plug 14, the water valve 1 is closed, and the nozzle 202 does not spray water. However, when the seat ring connecting shaft 22 moves between the highest and lowest positions, the plug notch 141 can connect with the eccentric water outlet 112, the water valve 1 is opened, and the nozzle 202 sprays water.

[0101] The specific process is as follows:

[0102] When the seat ring connecting shaft 22 is in the highest position, the plug notch 141 is on one side of the eccentric outlet 112, the two are disconnected, and the water valve 1 is closed.

[0103] When the user uses the seat ring 302, the seat ring 302 bears downward pressure. As the seat ring connecting shaft 22 moves from the highest position to the lowest position, the sliding rod 21 moves downward synchronously. Under the action of the swing transmission component 24, the rotating spindle 15 rotates in the forward direction. The plug notch 141 gradually connects with the eccentric water outlet 112, the water valve 1 opens, and the nozzle 202 sprays water to achieve the first pre-rinse.

[0104] When the seat ring connecting shaft 22 reaches its lowest position, the plug notch 141 rotates to the other side of the eccentric outlet 112, the two are disconnected, and the water valve 1 is closed.

[0105] When the user leaves the seat ring 302, under the action of the first elastic element 23, the seat ring connecting shaft 22 moves from the low high position to the highest position, and the sliding rod 21 moves upward synchronously. Under the action of the swing transmission component 24, the rotating spindle 15 rotates in the opposite direction. The plug notch 141 gradually connects with the eccentric water outlet 112, the water valve 1 opens, and the nozzle 202 sprays water to achieve the second pre-rinse.

[0106] When the user leaves the seat ring 302, the wall of the toilet bowl 3011 has already been rinsed with water. The second pre-rinse helps to prolong the wetting time of the wall of the toilet bowl 3011.

[0107] In this invention, the dimensions of the eccentric outlet 112, the dimensions of the plug notch 141, and the stroke of the seat ring connecting shaft 22 can be set as needed, as long as the aforementioned functions can be achieved.

[0108] In summary, the water valve control mechanism provided by this utility model controls the opening and closing of the water valve 1 by using the lifting and lowering of the seat ring 302 through the mechanical control module 2. The user does not need to specifically control the opening and closing of the nozzle 202. Moreover, the water valve 1 will only open when the seat ring 302 is subjected to a certain downward pressure and falls or is subjected to the reset driving force of the first elastic element 23 and rises. This overcomes the defect in the prior art that the nozzle 202 is accidentally opened due to the rotation of the seat ring 302.

[0109] In one embodiment, such as Figure 1-2 As shown, the swing transmission assembly 24 includes a connecting seat 241 and a swing bracket 242.

[0110] The sliding rod 21 is located on one side of the axis of the rotating spindle 15, and the connecting seat 241 is located on the side of the sliding rod 21 facing the rotating spindle 15. The connecting seat 241 is provided with a transverse adjustment hole 2412 extending toward the rotating spindle 15.

[0111] The swing bracket 242 includes a pivot shaft 2421 arranged parallel to the rotating spindle 15 and a connecting frame 2422 connected to the pivot shaft 2421.

[0112] The pivot shaft 2421 is slidably mounted in the transverse adjustment hole 2412.

[0113] The connecting bracket 2422 is connected to one end of the rotating spindle 15 and can drive the rotating spindle 15 to rotate.

[0114] In this embodiment, the swing transmission assembly 24 mainly consists of a connecting seat 241 and a swing bracket 242. The sliding rod 21 is arranged on one side of the axis of the rotating spindle 15.

[0115] The connecting seat 241 is fixedly connected to the sliding rod 21 and is located on the side facing the rotating spindle 15. The connecting seat 241 is provided with a lateral adjustment hole 2412, which extends towards the rotating spindle 15. In this invention, "lateral" refers to approximately along the horizontal direction, and "longitudinal" refers to approximately along the vertical direction. The length of the lateral adjustment hole 2412 is greater than its width, allowing the pivot shaft 2421 to rotate and slide within it. The lateral adjustment hole 2412 can be a rectangular hole, an oblong hole, etc.

[0116] The swing bracket 242 includes a pivot shaft 2421 and a connecting frame 2422. The pivot shaft 2421 is fixedly connected to the side of the connecting frame 2422 facing away from the rotating spindle 15. The pivot shaft 2421 is arranged parallel to the rotating spindle 15.

[0117] The pivot shaft 2421 is fitted into the transverse adjustment hole 2412. During the up-and-down sliding of the sliding rod 21, the pivot shaft 2421 can adaptively rotate and slide within the transverse adjustment hole 2412. The rotation of the pivot shaft 2421 functions as a hinge, and the sliding of the pivot shaft 2421 can adaptively adapt to changes in the distance between the connecting seat 241 and the rotating spindle 15.

[0118] One end of the rotating spindle 15 is connected to the connecting frame 2422, which drives the rotating spindle 15 to rotate. The connecting frame 2422 may be equipped with buckles, grippers, or engaging components for fastening to one end of the rotating spindle 15. During the up-and-down sliding of the sliding rod 21, the pivot shaft 2421 can adaptively rotate and slide within the transverse adjustment hole 2412, and the connecting frame 2422 will adaptively swing with the pivot shaft 2421, thereby driving the rotating spindle 15 to rotate. In this process, the connecting frame 2422 acts as a swing arm drive.

[0119] In one embodiment, such as Figure 1-2 As shown, the connecting frame 2422 has a support groove 2423, and the wall surface of the support groove 2423 is provided with a plurality of first teeth 2424.

[0120] One end of the rotating spindle 15 is provided with a second tooth 155.

[0121] One end of the rotating spindle 15 is fitted into the bracket groove 2423, and the first tooth 2424 meshes with the second tooth 155.

[0122] In this embodiment, the connecting frame 2422 is arranged vertically and has a support groove 2423, the opening of which faces the rotating spindle 15. The upper and lower walls of the support groove 2423 are provided with a plurality of first teeth 2424.

[0123] The end of the rotating spindle 15 that is assembled with the connecting frame 2422 is provided with a second tooth 155.

[0124] During assembly, the end of the rotating spindle 15 with the second tooth 155 is fitted into the bracket groove 2423, and the first tooth 2424 meshes with the second tooth 155. During the swinging of the connecting frame 2422, the meshing of the first tooth 2424 and the second tooth 155 ensures that the rotating spindle 15 rotates without slipping.

[0125] In one embodiment, such as Figure 1-2 As shown, the connecting seat 241 includes two spaced connecting seat sidewalls 2411, each of which is provided with a lateral adjustment hole 2412.

[0126] The pivot shaft 2421 is connected to the connecting frame 2422 in a T-shape.

[0127] One of the connecting seat sidewalls 2411 has a sidewall opening 2413 on its top surface for one end of the pivot shaft 2421 to enter and exit the transverse adjustment hole 2412.

[0128] In this embodiment, the pivot shaft 2421 and the connecting frame 2422 are connected in a T-shape, and the connecting frame 2422 is approximately connected to the middle of the pivot shaft 2421.

[0129] The connecting seat 241 has two connecting seat sidewalls 2411 on the side facing the rotating spindle 15. The connecting seat sidewalls 2411 are arranged vertically and are spaced apart from each other by a certain distance. Each connecting seat sidewall 2411 is provided with a horizontal adjustment hole 2412.

[0130] A side wall opening 2413 is provided on the top surface of one of the connecting seat side walls 2411 for one end of the pivot shaft 2421 to enter and exit the lateral adjustment hole 2412.

[0196] During assembly, the seat ring connecting shaft 22 is inserted into the seat ring connecting hole 3023, and the seat ring rotating shaft 3024 passes through the second vertical adjustment hole 2015 and can slide up and down relative to the second vertical adjustment hole 2015.

[0197] Thus, the seat ring connecting shaft 22 and the seat ring rotating shaft 3024 together form the pivot shaft of the seat ring 302, and the seat ring connecting shaft 22 and the seat ring rotating shaft 3024 can slide up and down relative to the first vertical adjustment hole 2014 and the second vertical adjustment hole 2015, respectively.

[0198] Preferably, a first elastic element 23 is also provided on the inner side of the second side plate 2012, which is used to drive the seat ring shaft 3024 to reset.

[0199] When no user is using seat ring 302, under the action of the first elastic element 23, seat ring connecting shaft 22 is at the upper end of the first vertical adjustment hole 2014, seat ring rotating shaft 3024 is at the upper end of the second vertical adjustment hole 2015, and plug notch 141 is on one side of the eccentric water outlet 112. The two are disconnected, water valve 1 is closed, and nozzle 202 does not spray water.

[0200] When a user uses the seat ring 302, the seat ring 302 is subjected to downward pressure, and the seat ring connecting shaft 22 and the seat ring rotating shaft 3024 move downward approximately synchronously. During the downward movement of the seat ring connecting shaft 22, the sliding rod 21 moves downward synchronously. Under the action of the swing transmission component 24, the rotating spindle 15 rotates in the forward direction, and the plug notch 141 gradually connects with the eccentric water outlet 112. The water valve 1 opens, and the nozzle 202 sprays water to achieve the first pre-rinse.

[0201] After the seat ring 302 is pressed onto the toilet body 301, the seat ring connecting shaft 22 and the seat ring rotating shaft 3024 reach their lowest positions in the first vertical adjustment hole 2014 and the second vertical adjustment hole 2015, respectively. When the seat ring connecting shaft 22 reaches the lower end of the first vertical adjustment hole 2014, the plug notch 141 rotates as a whole to the other side of the eccentric water outlet 112, the two are disconnected, and the water valve 1 is closed.

[0202] After the user leaves the toilet seat 302, the seat connecting shaft 22 and the seat rotating shaft 3024 return to their original positions upwards under the action of the first elastic element 23. During the upward reset of the seat connecting shaft 22, the sliding rod 21 moves upwards synchronously. Under the action of the swing transmission component 24, the rotating spindle 15 rotates in the opposite direction, and the plug notch 141 gradually connects with the eccentric water outlet 112. The water valve 1 opens, and the nozzle 202 sprays water to achieve a second pre-flushing. At this time, the wall surface of the toilet bowl 3011 has been flushed with water. The second pre-flushing helps to prolong the wetting time of the wall surface of the toilet bowl 3011.

[0203] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0204] The above are merely the principles and preferred embodiments of this utility model.
