Description

Technical Field

[0001] The present application relates to the field of bathroom fixtures, and in particular to a cover base lifting mechanism. Background Art

[0002] Smart toilets are common bathroom products, primarily consisting of a ceramic toilet body and a toilet cover. The base of the toilet cover is fixedly connected to the ceramic body, leaving a gap between the two. During daily use, impurities such as water stains, dust, and hair inevitably enter this gap, creating odor over time and affecting the appearance. To ensure comfortable use, this gap requires regular cleaning.

[0003] When cleaning existing smart toilets, users are required to first remove the toilet cover from the ceramic body. However, since the base is firmly connected to the ceramic body, it is difficult for ordinary users without assembly experience to operate and is not convenient to clean.

[0026] (3) Beneficial effects

[0027] Compared with the prior art, the technical solutions provided in the embodiments of the present application have at least the following beneficial effects:

[0028] The cover base lifting mechanism, toilet cover, and smart toilet of the present application install the mounting frame on the toilet body, and drive the sliding member and linkage assembly to move through a power source to realize the conversion of the cover base between the working state and the cleaning state. In the working state, the cover base is ensured to be used normally. In the cleaning state, the cover base is lifted to a certain height, thereby increasing the gap between the cover base and the toilet body, making it easier for users to clean the gap. Specifically, when the smart toilet is in normal use, the fixing assembly fixes the linkage assembly and the sliding member so that the bottom end of the sliding member is fixed in the first position. At this time, the cover base is at least partially arranged at the top end of the sliding member, in the normal first position, and the gap between it and the toilet body is small, meeting the needs of daily use. When the gap between the cover base and the toilet body needs to be cleaned, the user releases the fixing effect of the fixing assembly on the linkage assembly and the sliding member; the power source starts working, and under the drive of the power source, the bottom end of the sliding member begins to move after being unfixed in the first position. Since the bottom end of the first linkage member is rotatably set on the mounting frame, and its top end is rotatably connected to the top end of the sliding member, when the bottom end of the sliding member moves, it will drive the first linkage member to rotate, specifically, the top end of the first linkage member moves upward; at the same time, because the cover base is at least partially set at the top end of the sliding member, as the top end of the first linkage member moves upward, it will drive the top end of the sliding member to move upward, and then the part of the cover base set at the top end of the sliding member moves upward. In other words, after the fixing assembly is unlocked, under the drive of the driving source, the sliding member moves from the first position to the second position, at which time the cover base is lifted and the gap between it and the toilet body increases. The enlarged gap provides users with sufficient operating space, and users can easily use cleaning tools to clean the gap between the cover base and the toilet body. It is no longer difficult to reach or inconvenient to operate as in the first position, which greatly improves the convenience of cleaning. After cleaning is completed, the user can manually or by other means move the sliding member from the second position back to the first position, and the first linkage member will also rotate and reset accordingly. Finally, the linkage member and the sliding member are re-locked through the fixing assembly to restore the cover base to a normal working state. Compared with the structure of the existing smart toilet that requires the toilet cover to be disassembled as a whole before cleaning, the cover base lifting mechanism, toilet cover and smart toilet of the present application only need to release the lock of the fixing assembly on the linkage member and the sliding member to automatically lift the cover base without the need for overall disassembly, which is more convenient to use.

[0054] When cleaning existing smart toilets, users are required to first remove the toilet cover from the ceramic body. However, since the base is firmly connected to the ceramic body, it is difficult for ordinary users without assembly experience to operate and is not convenient to clean.

[0055] In order to solve the above technical problems, this embodiment provides a cover base lifting mechanism.

[0056] Figure 1 This is a three-dimensional diagram of the cover base lifting mechanism in the first position in the embodiment. Figure 2 This is a schematic diagram of the cover base lifting mechanism in the first position in the embodiment. Figure 3 This is a three-dimensional diagram of the cover base lifting mechanism in the second position in the embodiment. Figure 4 This is a schematic diagram of the cover base lifting mechanism in the second position in the embodiment. Figure 5 This is a schematic diagram of the first embodiment of the cover base lifting mechanism in the embodiment, which uses a compression spring as the driving source.

[0057] See Figures 1 to 5 As shown, this embodiment provides a cover base lifting mechanism, which includes: a mounting frame 100, a sliding member 200, a linkage assembly, a fixing assembly 400 and a power source 500.

[0058] The mounting bracket 100 is used to be mounted on the toilet body 800 and serves as a mounting base for the sliding member 200 , the linkage assembly, the fixing assembly 400 , and the power source 500 .

[0059] The bottom end of the sliding member 200 is slidably disposed on the mounting bracket 100 and is capable of sliding between a first position and a second position.

[0060] The linkage assembly includes a first linkage member 310 . The bottom end of the first linkage member 310 is rotatably disposed on the mounting bracket 100 , and the top end of the first linkage member 310 is rotatably connected to the top end of the sliding member 200 .

[0061] The fixing assembly 400 is disposed between the mounting frame 100 and the sliding member 200 or between the mounting frame 100 and the linkage assembly, and is used to releasably lock the linkage assembly and the sliding member 200 so that the bottom end of the sliding member 200 is locked in the first position.

[0062] The power source 500 is disposed on the mounting bracket 100 and connected to the sliding member 200 or the linkage assembly, and is used to drive the bottom end of the sliding member 200 to move from the first position to the second position when the bottom end of the sliding member 200 is unlocked at the first position.

[0063] In which, the cover base 600 is at least partially arranged at the top of the sliding member 200 or the first linkage member 310; the first position and the second position are arranged in sequence along the direction close to the first linkage member 310, and when the sliding member 200 moves from the first position to the second position, the top of the first linkage member 310 moves upward to make the part of the cover base 600 arranged at the top of the sliding member 200 move upward.

[0064] The cover base lifting mechanism, toilet cover 700 and smart toilet of the above technical solution drive the sliding part 200 and the linkage assembly to move through the power source 500, thereby realizing the conversion of the cover base 600 between the working state and the cleaning state. In the working state, the cover base 600 is ensured to be used normally. In the cleaning state, the cover base 600 is lifted to a certain height, thereby increasing the gap between the cover base 600 and the toilet body 800, making it convenient for users to clean the gap.

[0065] like Figure 2 and Figure 4 As shown, to enhance the stability and accuracy of the bottom sliding of the slider 200, a slide rail 130 is provided on the mounting frame 100 of the cover base lifting mechanism. The slide rail 130 extends parallel to the line connecting the first and second positions. The bottom end of the slider 200 is connected to the first slider 110 via a rotating shaft. The first slider 110 is slidably embedded in the slide rail 130, allowing the slider 200 to move along the slide rail 130 between the first and second positions.

[0066] like Figure 5 and Figure 6 As shown, Figure 6 This is a schematic diagram of the first embodiment of the cover base lifting mechanism in the embodiment, using a torsion spring as the driving source. In the first embodiment of the cover base lifting mechanism, the linkage assembly only includes the first linkage member 310, and the driving source can be a compression spring 510 or a torsion spring 520.

[0067] For example, Figure 2 、 5 As shown, the driving source is a compression spring 510. The mounting frame 100 is provided with a fixed base 120. The first slider 110 and the fixed base 120 are respectively provided with a spring hole 111 and a collar shaft 121. The spring hole 111 and the collar shaft 121 are arranged opposite each other, and their length directions are parallel to the line connecting the first position and the second position. The compression spring 510 is placed between the first slider 110 and the fixed base 120, so that the two ends of the compression spring 510 are respectively inserted into the spring hole 111 and the collar shaft 121. Under normal operating conditions, the compression spring 510 is in a certain state of compression, and its fixing assembly 400 fixes the slider 200 in the first position. When the gap between the cover base 600 and the toilet body 800 needs to be cleaned, the fixing assembly 400 is released from the locking mechanism and the slider 200. The elastic force of the compression spring 510 takes effect, pushing the first slider 110 along the slide rail 130, thereby driving the slider 200 from the first position to the second position.

[0068] For example, Figure 6As shown, the power source 500 is a torsion spring 520. The bottom end of the first linkage member 310 is connected to the mounting bracket 100 via a rotating shaft. The torsion spring 520 is mounted on the rotating shaft, with its ends respectively contacting the mounting bracket 100 and the first linkage member 310. Under normal operating conditions, the torsion spring 520 is in a certain torsion state, and its fixing assembly 400 fixes the first linkage member 310 and the sliding member 200 in the first position. When cleaning is required, the fixing assembly 400 is unlocked, and the torsional force of the torsion spring 520 begins to take effect, pushing the first linkage member 310 to rotate, thereby driving the sliding member 200 from the first position to the second position, lifting the cover base 600 and facilitating cleaning of the gap.

[0069] like Figure 2 and Figure 4 As shown, in the first embodiment of the cover base lifting mechanism, one end of the cover base 600 is connected to the mounting frame 100 through a rotating shaft, and the other end is directly or indirectly supported on the top of the sliding member 200. When the sliding member 200 moves to the second position, the cover base 600 rotates driven by the sliding member 200, and one end thereof is lifted, thereby facilitating the cleaning of the gap.

[0070] Figure 7 It is a principle diagram of the second implementation manner of the cover base lifting mechanism in the embodiment.

[0071] See Figure 7 As shown, in a second embodiment of the cover base lifting mechanism, the linkage assembly of the cover base lifting mechanism includes a first linkage member 310, a second linkage member 320, and a third linkage member 330. A corresponding mounting structure is provided on the mounting frame 100, to which the bottom end of the first linkage member 310 is rotatably mounted. The bottom end of the second linkage member 320 is also rotatably mounted on the mounting frame 100, and a second slider 340 is provided on its top end. The slider 200 is positioned between the first and second linkage members 310, 320. The top end of the slider 200 is provided with the third slider 210, and the bottom end is rotatably mounted on the first slider 110 on the mounting frame 100. The slider 200 is driven to move by a spring 510 on the fixed base 120. The third linkage member 330 has a structure similar to a slide bar, provided with a slot or track for the second and third sliders 340, 210 to slide. The second and third sliders 340, 210 are slidably mounted on the third linkage member 330. The cover base 600 is fixedly mounted on the third linkage member 330 .

[0072] During operation, when the sliding member 200 moves, the relative sliding and rotation between the first linkage member 310, the second linkage member 320 and the third linkage member 330 drive the movement of the third linkage member 330, thereby lifting the cover base 600, providing convenience for cleaning the gap between the cover base 600 and the toilet body 800.

[0073] Figure 8 It is a principle diagram of the third implementation manner of the cover base lifting mechanism in the embodiment.

[0074] See Figure 8 As shown, in a third embodiment of the cover base lifting mechanism, the linkage assembly includes a first linkage member 310, a second linkage member 320, and a third linkage member 330. A fourth slider 140 and a fifth slider 150 are slidably mounted on the mounting frame 100, for example, via guide rails or guide slots. The sliding directions of the fourth slider 140 and the fifth slider 150 are parallel to the sliding direction of the first slider 110. The bottom end of the first linkage member 310 is rotatably mounted on the fourth slider 140, and the bottom end of the second linkage member 320 is rotatably mounted on the fifth slider 150. The top end of the second linkage member 320 is provided with a second slider 340. The slider 200 is positioned between the first and second linkage members 310, 320, and has a third slider 210 mounted on its top end. The second and third sliders 340 and 210 are slidably mounted on the third linkage member 330, and the cover base 600 is mounted on the third linkage member 330.

[0075] When cleaning is required, the sliding member 200 moves, and through the coordinated movement between the first linkage member 310, the second linkage member 320 and the third linkage member 330, the third linkage member 330 drives the cover base 600 to lift, making it convenient to clean the gap between the cover base 600 and the toilet body 800.

[0076] Figure 9 2 is a schematic diagram of a fourth embodiment of the cover base lifting mechanism in the embodiment.

[0077] See Figure 9 As shown, in the fourth embodiment of the cover base lifting mechanism, the linkage assembly includes a first linkage member 310, a second linkage member 320 and a third linkage member 330. A fourth slider 140 and a fifth slider 150 are slidably provided on the mounting frame 100, and their sliding directions are parallel to the sliding direction of the first slider 110. The bottom end of the first linkage member 310 is rotatably mounted on the fourth slider 140, and the top end thereof is rotatably connected to the top end of the sliding member 200 and the third linkage member 330, and their rotation center lines are the same. The bottom end of the second linkage member 320 is rotatably mounted on the fifth slider 150, and the top end thereof is rotatably connected to the third linkage member 330, and the cover base 600 is mounted on the third linkage member 330.

[0078] During operation, the movement of the sliding member 200 drives the movement of the first linkage member 310 and the second linkage member 320 , and then lifts the cover base 600 through the third linkage member 330 , providing sufficient space for the cleaning operation.

[0079] Figure 10 It is a principle diagram of the fifth implementation manner of the cover base lifting mechanism in the embodiment.

[0080] See Figure 10 As shown, in the fifth embodiment of the cover base lifting mechanism, the linkage assembly includes a first linkage member 310, a second linkage member 320 and a third linkage member 330. A fourth slider 140 is slidably provided on the mounting frame 100, and the sliding direction of the fourth slider 140 is parallel to the sliding direction of the first slider 110. The slider 200 is located between the first linkage member 310 and the second linkage member 320, and the second slider 210 is provided on the top thereof. The bottom end of the first linkage member 310 is rotatably mounted on the fourth slider 140, and the top end thereof is rotatably connected to the second slider 210. The bottom end of the second linkage member 320 is rotatably mounted on the mounting frame 100, and the top end thereof is rotatably connected to the third linkage member 330, and the cover base 600 is mounted on the third linkage member 330.

[0081] When it is necessary to clean the gap between the cover base 600 and the toilet body 800, the sliding member 200 moves, and through the linkage relationship between the first linkage member 310, the second linkage member 320 and the third linkage member 330, the cover base 600 can be lifted to facilitate cleaning of the gap.

[0082] In the above embodiment, the cover base 600 can be mounted on the third linkage member 330 by means of bolts or buckles, so that it moves synchronously with the third linkage member 330 .

[0083] The above-mentioned rotatable connection can be achieved by existing methods, such as connecting through a rotating shaft. The rotation center lines of the rotational connection between the above-mentioned sliding member 200, the linkage assembly, and the slider are parallel to each other.

[0084] The fixing assembly 400 can utilize an existing mechanism capable of locking a rotating member or a sliding member, such as a snap or latch mechanism. As shown in FIG2 , taking the latch mechanism as an example, the latch mechanism includes a latch 410 mounted on the mounting frame 100 , and a pin hole provided on the sliding member 200 or any of the linkage members of the linkage assembly. The latch 410 is inserted into the pin hole to prevent the sliding member 200 from sliding or any of the linkage members from rotating, thereby locking the sliding member 200 and the linkage assembly. To unlock, simply remove the latch 410 from the pin hole.

[0085] A groove 160 is provided at the top of the mounting frame 100. When the bottom end of the sliding member 200 is in the first position, the sliding member 200, the linkage assembly, the fixing assembly 400 and the power source 500 are all arranged in the groove 160 and will not protrude from the top of the mounting frame 100, so that the upper end of the cover base lifting mechanism is flatter and similar in size and appearance to the mounting base of the existing toilet cover 700.

[0086] This embodiment discloses a toilet cover 700, which includes the cover base lifting mechanism of any of the above-mentioned embodiments and the cover base 600. The cover base lifting mechanism provides the cover base 600 with the function of lifting and moving. When the gap between the cover base 600 and the toilet body 800 needs to be cleaned, the cover base lifting mechanism can lift the cover base 600, making it easier for the user to perform the cleaning operation.

[0087] This embodiment discloses a smart toilet, comprising the aforementioned toilet cover 700 and a toilet body 800. The mounting bracket 100 is fixedly attached to the toilet body 800 using a suitable mounting method. During daily use, the toilet cover 700 functions normally. When the gap between the cover base 600 and the toilet body 800 needs to be cleaned, the cover base lifting mechanism within the toilet cover 700 lifts the cover base 600, providing convenient cleaning conditions for the user and ensuring a hygienic and user-friendly toilet.

[0088] To sum up, when the cover base lifting mechanism, toilet cover 700 and smart toilet of the present application are in normal use, the fixing component 400 fixes the linkage component and the sliding member 200, so that the bottom end of the sliding member 200 is fixed in the first position. At this time, the cover base 600 is at least partially arranged at the top end of the sliding member 200 and is in the normal first position. The gap between it and the toilet body 800 is small, which meets the needs of daily use. When it is necessary to clean the gap between the cover base 600 and the toilet body 800, the user releases the fixing effect of the fixing component 400 on the linkage component and the sliding member 200; the power source 500 starts to work, and under the drive of the power source 500, the bottom end of the sliding member 200 starts to move after being unfixed in the first position. Since the bottom end of the first linkage member 310 is rotatably set on the mounting frame 100, and its top end is rotatably connected to the top end of the sliding member 200, when the bottom end of the sliding member 200 moves, it will drive the first linkage member 310 to rotate, specifically, the top end of the first linkage member 310 moves upward; at the same time, because the cover base 600 is at least partially set at the top end of the sliding member 200, as the top end of the first linkage member 310 moves upward, it will drive the top end of the sliding member 200 to move upward, and then the part of the cover base 600 set at the top end of the sliding member 200 moves upward. That is, after the fixing assembly 400 is unlocked, the slider 200, driven by the driving source, moves from the first position to the second position. At this point, the cover base 600 is lifted, and the gap between it and the toilet body 800 increases. The increased gap provides the user with sufficient operating space, allowing the user to conveniently use cleaning tools to clean the gap between the cover base 600 and the toilet body 800 without the difficult access or inconvenience of operation as in the first position, greatly improving the convenience of cleaning. After cleaning is complete, the user can manually or through other means move the slider 200 from the second position back to the first position. At the same time, the first linkage member 310 will also rotate and reset accordingly. Finally, the fixing assembly 400 relocks the linkage assembly and the slider 200, restoring the cover base 600 to its normal operating state.

[0089] Compared with the existing smart toilet structure that requires the toilet cover 700 to be disassembled as a whole for cleaning, the cover base lifting mechanism, toilet cover 700 and smart toilet of the present application only need to release the lock of the fixing component 400 on the linkage and sliding part 200 to automatically lift the cover base 600 without the need for overall disassembly, which is more convenient to use.
