Description

Technical Field

[0001] This utility model relates to the field of toilet technology, and in particular to a toilet with a differentially adjustable toilet seat assembly. Background Technology

[0002] A toilet mainly consists of a ceramic toilet seat and a toilet seat assembly located above the toilet seat. The toilet seat assembly mainly consists of three parts: a ring-shaped seat, a cover plate that covers the seat, and a connecting seat. The connecting seat may or may not have functional components. Functional components usually include drying components, bidet components, etc. The seat and cover plate are rotatably connected to the connecting seat.

[0003] The toilet seat assembly is installed on the toilet seat, and because its rear end is assembled with the toilet seat, a portion of it is always difficult to clean thoroughly. To solve this cleaning problem, toilet products with adjustable toilet seat assemblies have emerged. For example, Chinese patent document CN216167149U provides a mechanism for realizing the lifting function of the toilet seat assembly.

[0004] This type of toilet product uses a push-up mechanism and a locking mechanism to raise and lower the toilet seat assembly. The push-up mechanism allows the toilet seat assembly to rise after the locking mechanism is unlocked. After the toilet seat assembly rises, the rear part of the toilet seat assembly that was originally covered is exposed. After cleaning this part, the toilet seat assembly is lowered back to its original position.

[0005] Currently, due to factors such as manufacturing tolerances, this type of toilet product generally has the problem that although the toilet seat assembly has been lowered back to its original position, there is still a noticeable gap between the top surface of the toilet seat and the toilet seat assembly. Utility Model Content

[0006] The technical problem to be solved by this utility model is: how to achieve the lifting function of the toilet seat assembly, and how to ensure that the top surface of the toilet seat and the toilet seat assembly fit tightly together after the toilet seat assembly is lowered back to its original position.

[0007] To solve this technical problem, this utility model provides a toilet with a differentially adjustable toilet seat assembly. The toilet includes a toilet seat assembly, a toilet seat, a pushing mechanism, a resetting mechanism, and a locking mechanism. The toilet seat assembly is positioned above the toilet seat. The pushing mechanism pushes the toilet seat assembly from a low position to a high position after the locking mechanism is unlocked. The resetting mechanism returns the pushing mechanism to its original position, allowing the locking mechanism to lock the pushing mechanism in place. The key feature is that when the toilet seat assembly is in the low position, the toilet seat assembly and the toilet seat... The top surface of the toilet seat is in contact with the toilet seat. The pushing mechanism has a pushing surface for pushing the toilet seat assembly to rise. After the locking mechanism is unlocked, the pushing surface moves relative to the toilet seat from a first position, through a second position, to a third position, and pushes the toilet seat assembly from a low position to a high position. When the toilet seat assembly is in the high position, the reset mechanism is used to lower the pushing surface from the third position, through a second position, to the first position. When the pushing surface is in the second and third positions, it is in contact with the toilet seat assembly. When it is in the first position, the pushing surface is separated from the toilet seat assembly.

[0008] Furthermore, the push mechanism is located inside the toilet and includes an elastic element and a push member. The elastic element is located between the toilet seat and the push member. After the locking mechanism is unlocked, the push member moves upward under the push of the elastic element, and the push member has the push surface.

[0009] Furthermore, the reset mechanism includes a reset block, which is driven and cooperates with the push mechanism. The reset block is movably mounted on the toilet seat assembly. The toilet seat assembly is provided with a clearance hole that matches the reset block. The reset block passes through the clearance hole and can move up and down relative to the clearance hole.

[0010] Furthermore, the toilet seat assembly includes a toilet seat housing, and the reset mechanism includes a triggering device provided on the toilet seat housing corresponding to the push surface. The triggering device is elastic or movably connected to the toilet seat housing, and an external force pushes the push surface downward through the triggering device.

[0011] Furthermore, the push-up component includes a floating seat and a screw joint. The screw joint is screwed to the upper end of the floating seat, allowing the screw joint to be adjusted up and down relative to the floating seat. The screw joint has the push-up surface, and an elastic element is disposed between the toilet seat body and the floating seat.

[0012] Furthermore, the push mechanism is equipped with a locking part, which cooperates with the locking part and is connected to the toilet seat to lock the push mechanism.

[0013] The locking part includes a buckle or a slot, and the locking mechanism includes a mounting base connected to the toilet seat, a pin, and a reset member. The reset member abuts between the mounting base and the pin, and the pin is slidably disposed within the mounting base and can pass through the mounting base to engage with the buckle or slot. Alternatively, the locking mechanism includes a buckle or a slot connected to the toilet seat, and the locking part includes a mounting base, a pin, and a reset member connected to the pushing mechanism. The reset member abuts between the mounting base and the pin, and the pin is slidably disposed within the mounting base and passes through the mounting base to engage with the buckle or slot.

[0014] Furthermore, when the locking part includes a buckle or a slot, the locking mechanism also includes a pulling component; when the locking mechanism includes a buckle or a slot connected to the toilet seat, the locking part also includes a pulling component; the pulling component engages with the pin to drive the pin out of the buckle or slot.

[0015] Furthermore, the toilet also includes a fixed seat, which is fixedly connected to the toilet seat body. The pushing mechanism includes an elastic element and a pushing element. The pushing element is sleeved on the fixed seat, and the elastic element is located between the fixed seat and the pushing element. The pushing element is provided with a locking part, and the locking mechanism is connected to the fixed seat. By cooperating with the locking part, the pushing element is locked. The elastic element is a spring sleeved on the fixed seat and compressed by the pushing element and the fixed seat.

[0016] When the locking mechanism includes a buckle or slot connected to the toilet seat: the mounting base is provided on the push member, the mounting base includes an assembly cavity and a locking block fixedly installed in the assembly cavity; the pin is slidably disposed in the assembly cavity, and the reset member abuts between the pin and the locking block; the locking mechanism is at least one slot provided on the side of the fixed base, the inner side of the pin is provided with a protrusion corresponding to the slot, the protrusion is inserted into the corresponding slot to realize the locking mechanism locking the push member, and the protrusion is disengaged from the corresponding slot to realize the locking mechanism unlocking the push member.

[0017] Furthermore, the toilet also includes a limiting pin, which is fixedly connected to the pusher. The fixed seat has a limiting hole corresponding to the limiting pin. The limiting pin passes through the limiting hole and the limiting hole limits the range of vertical movement of the pusher relative to the fixed seat.

[0018] Furthermore, the toilet also includes a guide post, which is fixed to the toilet seat or toilet lid assembly and is used to guide the raising and lowering of the toilet lid assembly.

[0019] The advantages of this invention are as follows: By designing the push-up surface with two travel segments—between the first and second positions, and between the second and third positions—the push-up surface descends together with the toilet seat assembly until it is in contact with the top surface of the toilet seat. Then, the push-up surface can descend a further distance (from the second position to the first position), thus solving the problem of a noticeable gap between the top surface of the toilet seat and the toilet seat assembly mentioned in the background art. Furthermore, because the locking mechanism maintains a gap between the push-up surface and the toilet seat assembly after locking the push-up mechanism, the toilet seat assembly is not continuously subjected to the force of the push-up mechanism when it is in the lower position, thereby increasing the service life of both the push-up mechanism and the toilet seat assembly and reducing damage. This invention also has a high tolerance for manufacturing tolerances. Attached Figure Description

[0029] The improvement of the prior art by this utility model is focused on the mechanism for realizing the lifting function of the toilet seat assembly. The parts of the toilet seat and toilet seat assembly that are not related to the improvement of this utility model will not be described in detail.

[0030] The mechanism provided by this utility model for realizing the lifting function of the toilet seat assembly can be applied to smart toilets, as well as other types of toilets.

[0031] The specific embodiments of this utility model are described below by way of examples.

[0032] Example 1:

[0033] Figure 1 , 2 Figure 3 illustrates the three states of the toilet in this embodiment. Figure 6 The structure of the toilet seat assembly 1 in this embodiment is shown; Figure 1 , 2 The seat ring and cover of toilet seat assembly 1 are not shown in 3 and 6.

[0034] See Figure 1 When the toilet seat assembly 1 is in the high position, there is a relatively large gap G1 between it and the top surface of the toilet seat 2, facilitating cleaning. In addition to the toilet seat assembly 1 and the toilet seat 2, the toilet also includes a push-up mechanism 3, a reset mechanism, and a locking mechanism. The reset mechanism returns the push-up mechanism 3 to its original position. The locking mechanism locks the push-up mechanism 3 after it has returned to its original position. The push-up mechanism 3 then pushes the toilet seat assembly 1 from the low position to the high position after the locking mechanism is unlocked. See also... Figure 2 and 3 When the toilet seat assembly 1 is in the low position, the toilet seat assembly 1 is in contact with the top surface of the toilet seat 2. Figure 1 The gap G1 disappears as the toilet seat assembly 1 descends from the high position to the low position.

[0035] The push mechanism 3 has a push surface P for pushing the toilet seat assembly 1 up. After the locking mechanism is unlocked, the push surface P is positioned relative to the toilet seat 2 from a first position (see [reference]). Figure 3 ) via the second position (see Figure 2 Move it to the third position (see) Figure 1 And if you want the toilet to go from Figure 1 State restored Figure 3 In this state, the jacking surface P needs to be lowered from the third position through the second position back to the first position.

[0036] See Figure 3 When the push-pull surface P is in the first position, it separates from the toilet seat assembly 1; that is, there is a gap G2 between the push-pull surface P and the inner side of the toilet seat assembly 1. (See also...) Figure 2 When the push surface P is in the second position, the push surface P contacts the toilet seat assembly 1. Figure 3 The gap G2 disappears as the pushing surface P rises while the toilet seat assembly 1 remains in the same position. (See also...) Figure 2 and 1During the process of the push surface P moving from the second position to the third position, it maintains contact with the toilet seat assembly 1, and pushes the toilet seat assembly 1 from the low position to the high position.

[0037] The pushing mechanism 3 is equipped with a locking part 4, and the toilet seat 2 is equipped with a locking mechanism. The pushing mechanism 3, the locking part 4, and the locking mechanism can all be implemented using existing mechanical structures, which can be selected by those skilled in the art. See [link to relevant documentation] Figure 4 In this embodiment, the pushing mechanism 3 includes an elastic element 31 and a pushing element 32. The pushing surface P is the top surface of the pushing element 32. The elastic element 31 is disposed between the toilet seat 2 and the pushing element 32. The locking mechanism locks the pushing mechanism 3 by preventing the pushing element 32 from moving relative to the toilet seat 2. After the locking mechanism is unlocked, the pushing element 32 moves upward under the push of the elastic element 31.

[0038] In this embodiment, the pusher 32 includes a floating seat 321 and a screw connector 322. The pusher surface P is the top surface of the screw connector 322. The screw connector 322 is screwed to the upper end of the floating seat 321, allowing the screw connector 322 to be adjusted vertically relative to the floating seat 321. The size of the gap G2 can be adjusted by adjusting the screw connector 322.

[0039] Toilet seat assembly 1 includes a toilet seat housing 11. The toilet seat housing 11 has a mounting hole (not shown in the figure) corresponding to the push-up surface P. The push-up surface P is located below the mounting hole. The reset mechanism includes a trigger device (not shown in the figure) disposed on the toilet seat housing 11 in the mounting hole. External force pushes the push-up surface P downward through the trigger device. The trigger device is elastic or movably connected to the toilet seat housing 11. For example, the trigger device is an elastic cover disposed in the mounting hole, and the edge of the elastic cover is fixed to the toilet seat housing 11. For example, the trigger device is a plastic cover disposed in the mounting hole, and the edge of the plastic cover is slidably connected to the toilet seat housing 11, so that the plastic cover can move up and down relative to the mounting hole.

[0040] The screw connector 322 prevents situations where the gap G2 is too large, requiring excessive deformation of the elastic cover (trigger device) to return the push surface P from the second position to the first position, or requiring the plastic cover (trigger device) to be pushed too far to return the push surface P from the second position to the first position, thus affecting the user experience. It also prevents situations where the push surface P remains in contact with the trigger device even when in the first position, or even causes the trigger device to bulge and deform. In other embodiments of this invention, the trigger device can also be an elastic part on the toilet seat shell 11 relative to the push surface P. This elastic part can undergo a certain deformation after being pressed, and the elastic part can be integrally formed with the toilet shell 11.

[0041] In this embodiment, the locking part 4 includes a pin 41, a reset member 42, a mounting base 44, and a pulling assembly 43. The pushing force of the reset member 42 on the pin 41 is opposite to the pulling force of the pulling assembly 43 on the pin 41 after activation. The mounting base 44 is disposed on the push member 32 and includes an assembly cavity 441 and a locking block 442 fixedly installed in the assembly cavity 441. The pin 41 is slidably disposed in the assembly cavity 441. The reset member 42 abuts against the pin 41 and the locking block 442. One end of the reset member 42 is fixedly connected to the pin 41, and the other end is fixedly connected to the locking block 442. The pulling assembly 43 passes through the locking block 442 and is fixedly connected to the pin 41. In this embodiment, the reset member 42 is a spring.

[0042] In this embodiment, the toilet also includes a fixed seat 5, which is fixedly connected to the toilet seat body 2. The push member 32 is sleeved on the fixed seat 5. The locking mechanism is a slot 51 provided on the side of the fixed seat 5. The fixed seat 5 is provided with two slots 51. The locking part 4 is connected to the push member 32. The locking part 4 locks the push member 32 by cooperating with the two slots 51. The elastic member 31 is provided between the fixed seat 5 and the push member 32.

[0043] In this embodiment, the pin 41 has a U-shaped structure, and its inner side has two opposing protrusions 411, corresponding to two slots 51 respectively. See also Figure 5 The protrusion 411 inserts into the corresponding slot 51, locking the pusher 32 by the locking mechanism. The pulling assembly 43 pulls the pin 41, causing the protrusion 411 to disengage from the corresponding slot 51, thus unlocking the pusher 32 by the locking mechanism. See also Figure 4 The protrusion 411 has a first guide slope S1, and the fixing seat 5 has a second guide slope S2 corresponding to the first guide slope S1. The first guide slope S1 and the second guide slope S2 are opposite to each other. During the process of pressing down the push member 32, the first guide slope S1 contacts the second guide slope S2, causing the pin 41 to move away from the fixing seat 5. After further pressing down the push member 32, the pin 41 moves towards the fixing seat 5 because the protrusion 411 encounters the slot 51, and the protrusion 411 is inserted into the slot 51, completing the locking of the push member 32. Through the guidance of the second guide slope S2 on the first guide slope S1, the movement of the push member 32 is successfully converted into the movement of the pin 41.

[0044] See Figure 6In this embodiment, the pulling assembly 43 mainly includes a switch module 431 and a steel wire rope 432. The switch module 431 is fixed to the toilet seat assembly 1. The button of the switch module 431 protrudes from an opening on the toilet seat housing 11. Pressing the button activates the pulling assembly 43, causing the steel wire rope 432 to pull the pin 41 away from the fixed seat 5. During the movement of the pin 41 away from the fixed seat 5, when the protrusion 411 is completely disengaged from the slot 51, the pusher 32 moves upward under the push of the elastic member 31. In other embodiments of this utility model, the switch module 431 can also be a pull ring.

[0045] In this embodiment, the toilet also includes a limiting pin 6, which is fixedly connected to the push member 32. The fixed base 5 is provided with a limiting hole 52 corresponding to the limiting pin 6. The limiting pin 6 passes through the limiting hole 52 and the limiting hole 52 limits the movement range of the push member 32 relative to the fixed base 5.

[0046] In this embodiment, the elastic element 31 is a spring that is mounted on the fixed base 5 and compressed by the pushing element 32 and the fixed base 5.

[0047] In this embodiment, the toilet also includes two guide posts 7, one thick and one thin, which are fixed on the toilet seat assembly 1 and used to guide the raising and lowering of the toilet seat assembly 1.

[0048] In this embodiment, the toilet seat assembly 1 is provided with a sleeve 111 for guiding the up and down movement of the push member 32. The push member 32 passes through the sleeve 111 and moves up and down relative to the toilet seat assembly 1.

[0049] Example 2:

[0050] Figure 7 and 8 This embodiment demonstrates two states of the toilet. Figure 7 In the middle, the jacking surface P is located in the first position, in Figure 8 In this embodiment, the jacking surface P is located in the third position. The difference between this embodiment and Embodiment 1 is as follows:

[0051] In this embodiment, a reset block B is provided on the push surface P of the push member 32, and a clearance hole is provided on the toilet seat housing 11 corresponding to the reset block B, through which the reset block B can pass through the toilet seat housing 11.

[0052] In this embodiment, the pusher 32 is provided with a latch 323 as a locking part. The locking mechanism 4' includes a pin 41', a reset member 42', a pulling component 43', and a mounting base 44'. The locking mechanism 4' cooperates with the latch 323 to lock the pusher 32. The latch 323 is located on the side of the pusher 32. The first guide slope S1 is located on the pin 41', and the second guide slope S2 is located on the latch 323. By pressing the reset block B, the pusher 32 moves downward. When the second guide slope S2 contacts the first guide slope S1 of the pin 41', the pusher surface P has not yet reached the first position. The latch 323 causes the pin 41' to move away from the pusher 32. After the latch 323 passes, the pin 41' limits the latch 323, thus locking the pusher 32.

[0053] In this embodiment, the mounting plate 8 is connected to the toilet seat 2, the pusher 32 passes through the mounting plate 8, the elastic element 31 is a spring compressed by the pusher 32 and the mounting plate 8, and the mounting seat 44' is provided on the mounting plate 8. The lower end of the pusher 32 is provided with a limiting protrusion 324, and the upward movement of the pusher 32 is limited by the obstruction of the limiting protrusion 324 by the mounting plate 8. In other embodiments of this utility model, the elastic element 31 may also be a pneumatic rod, etc.

[0054] The above embodiments one and two are only two embodiments of this utility model. Those skilled in the art can obtain other embodiments that conform to the inventive concept of this utility model without creative effort, using their knowledge. These embodiments should also fall within the protection scope of this utility model.
