Description

Technical Field

[0001] The present application relates to the field of sanitary ware, and particularly to a cover base lifting device and a smart toilet. Background Art

[0002] In modern home life, smart toilets have greatly improved people's quality of life with their convenient, comfortable and intelligent functions. Existing smart toilets mainly include a ceramic toilet body and a toilet cover. Among them, the toilet cover includes an upper cover, a seat ring, a body assembly and a cover base. As the installation carrier of the upper cover, seat ring and body assembly, the cover base is installed on the toilet body through a specific fixing method.

[0003] However, due to a certain gap between the cover base and the toilet body, during daily use, impurities such as water stains, dust, and hair will inevitably enter this gap. Over time, these impurities will gradually accumulate, not only affecting the overall beauty of the bathroom, but more seriously, it will breed a large number of bacteria and odors, affecting the health and use experience of users.

[0004] To keep the bathroom clean and healthy, users need to regularly clean the gap between the cover base and the toilet body. However, the current cleaning method has great inconveniences. Before cleaning, users usually need to first remove the toilet cover from the toilet body. This process is not only cumbersome, but for users lacking relevant experience or with weak hands-on ability, disassembling and reinstalling the toilet cover may encounter many difficulties and may even cause damage to the toilet cover.

[0005] Therefore, how to design a new installation structure for the smart toilet cover base that can conveniently and quickly clean the gap between the base and the toilet body and avoid dirt accumulation has become an urgent technical problem in this field.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0007] (I) Technical Problems to be Solved

[0008] Embodiments of the present application provide a cover base lifting device, a toilet cover and a smart toilet, which can solve the problem of how to improve the convenience of cleaning the gap between the base and the toilet body in the prior art.

[0009] (II) Technical Solutions

[0010] To solve the above technical problems, the present application provides the following technical solutions:

[0011] On the one hand, a cover base lifting device is provided, and the cover base lifting device includes:

[0012] A fixed seat for mounting on the toilet body;

[0013] A connecting rod assembly disposed at the upper end of the fixed seat. The connecting rod assembly includes a first connecting rod, a second connecting rod, and a third connecting rod. The first connecting rod and the second connecting rod are respectively rotatably disposed at different positions of the fixed seat and are both rotatably connected to the third connecting rod. The first connecting rod is capable of rotating between a first position and a second position, and the first connecting rod rotates upward from the first position to the second position;

[0014] A locking mechanism disposed on the fixed seat and used to fix the connecting rod assembly so that the first connecting rod is fixed at the first position;

[0015] A driving mechanism disposed on the fixed seat and connected to the connecting rod assembly for driving the first connecting rod to rotate from the first position to the second position when the fixing of the first connecting rod at the first position is cancelled;

[0016] Wherein, the third connecting rod is used to mount the cover base. When the first connecting rod rotates from the first position to the second position, the third connecting rod moves obliquely upward.

[0017] In some embodiments of the cover base lifting device, the driving mechanism includes a driving element, a slider, and a push rod. The fixed seat is provided with a linear slide rail. The slider is slidably disposed on the slide rail. One end of the push rod is rotatably connected to the slider, and the other end is rotatably connected to the first connecting rod. The driving element is disposed between the slider and the fixed seat. When the first connecting rod is in the second position, a triangular structure is formed among the first connecting rod, the push rod, and the fixed seat;

[0018] In the first position, the driving element includes an elastic member, and the elastic member is compressed; when the fixing of the first connecting rod at the first position is cancelled, the elastic member of the driving element drives the slider to move along the slide rail towards the first connecting rod by elastic force, and the slider moves to push the push rod, thereby driving the first connecting rod to rotate towards the second position.

[0019] In some embodiments of the cover base lifting device, the driving element is a spring. The slider and the fixed seat are respectively provided with a guide hole and a guide post, and the two ends of the spring are respectively disposed in the guide hole and the guide post.

[0020] In some embodiments of the cover plate base lifting device, the driving mechanism includes a torsion elastic member disposed at the rotational connection of the first link and / or the second link with the fixed seat; in the first position, the torsion elastic member is compressed; when the fixation of the first link at the first position is released, the torsion elastic member drives the first link to rotate towards the second position by its elastic force.

[0021] In some embodiments of the cover plate base lifting device, the driving mechanism includes a torsion elastic member and a rotating rod. The rotating rod is located between the first link and the second link and below the third link. The bottom end of the rotating rod is rotatably connected to the fixed seat, and the top end of the rotating rod is rotatably connected to the third link. The torsion elastic member is disposed at the rotational connection of the rotating rod with the fixed seat; in the first position, the torsion elastic member is compressed; when the fixation of the first link at the first position is released, the torsion elastic member drives the rotating rod to rotate upward by its elastic force, and the rotating rod drives the third link to move, so as to drive the first link to rotate towards the second position.

[0022] In some embodiments of the cover plate base lifting device, the driving mechanism includes a torsion elastic member, a rotating rod and a sliding member. The rotating rod is located between the first link and the second link and below the third link. The bottom end of the rotating rod is rotatably connected to the fixed seat, and the top end of the rotating rod is rotatably connected to the sliding member. The sliding member is disposed on the third link and can slide along the length direction of the third link. The torsion elastic member is disposed at the rotational connection of the rotating rod with the fixed seat; in the first position, the torsion elastic member is compressed; when the fixation of the first link at the first position is released, the torsion elastic member drives the rotating rod to rotate by its elastic force, and the rotating rod drives the sliding member to slide on the third link, so that one end of the third link drives the first link to rotate towards the second position.

[0023] In some embodiments of the cover plate base lifting device, the self-locking mechanism includes a clamping shaft. The second link and the third link are rotatably connected through the clamping shaft, and the fixed seat is provided with a clamping groove; when the first link is in the first position, the clamping shaft is clamped in the clamping groove.

[0024] In some embodiments of the cover plate base lifting device, the upper end of the fixed seat is provided with a receiving groove. When the first link is in the first position, the first link, the second link and the driving mechanism are located in the receiving groove.

[0025] On the other hand, a toilet cover plate is disclosed. The toilet cover plate includes the cover plate base lifting device described in any one of the above, and further includes a cover plate base. A cover plate is provided on the cover plate base. The distance from the front end of the cover plate to the first link is closer than the distance to the second link. When the first link is in the first position, the cover plate base fits onto the fixed seat. When the first link is in the second position, the cover plate base is lifted by the cover plate base lifting device.

[0026] On yet another aspect, an intelligent toilet is disclosed. The intelligent toilet includes the above-mentioned toilet cover plate and further includes a toilet main body. The fixed seat of the cover plate base lifting device is fixedly installed on the toilet main body.

[0027] (III) Beneficial effects

[0028] Compared with the prior art, the beneficial effects brought by the technical solutions provided in the embodiments of the present application at least include:

[0029] During normal use of the cover plate base lifting device, toilet cover plate and intelligent toilet of the present application, the cover plate base lifting device is in an initial state: the first link is in the first position and the entire link assembly is fixed by the locking mechanism; under the connection of the link assembly, the third link enables the cover plate base to be normally installed on the toilet main body to meet the daily use requirements of the toilet. When the user needs to clean the gap between the base and the toilet main body, the locking mechanism releases the fixation on the first link, allowing the first link to be released from the locked first position and rotate freely; subsequently, the driving mechanism operates. Under the action of the driving mechanism, the first link starts to rotate from the first position to the second position. Since both ends of the third link are rotatably connected to the first link and the second link respectively, as the first link rotates, the third link will be subjected to force. According to the movement principle of the link mechanism, the third link will move along a trajectory of moving upward and towards the first link; then, the cover plate base installed on the third link is also lifted accordingly, and the cover plate base gradually moves away from the toilet main body, and the gap between the two continuously increases. When the first link rotates to the second position, the cover plate base reaches the maximum lifting height, and at this time, the gap between the base and the toilet main body reaches the maximum, providing sufficient space for the cleaning work, thereby facilitating the user to clean the toilet main body. After the cleaning is completed, the link assembly and the driving mechanism are controlled to move in the reverse direction. When the first link returns to the first position, the locking mechanism fixes the first link at the first position again, causing the entire link assembly to return to the initial state, and the cover plate base also closely fits on the toilet main body, and the toilet returns to the normal use state.

[0030] Equally importantly, when the third link rotates from the first position to the second position, it can drive the cover base forward and upward, preventing the cover base from hitting the water tank or wall at the rear, so that almost no space needs to be reserved between the cover base and the water tank or wall, and it can meet the cleaning requirements of more types of intelligent toilets.

[0031] It can be seen that when the cover base lifting device of the present application needs to be cleaned, the driving mechanism drives the link assembly to move, thereby driving the cover base to lift, increasing the gap between the base and the toilet body, and thus improving the convenience of cleaning.

[0054] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Specific embodiments

[0055] The following will further elaborate on the present disclosure in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the relevant content and do not limit the present disclosure. Additionally, it should be noted that for the sake of convenience of description, only parts related to the present disclosure are shown in the drawings.

[0056] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. The following will detail the technical solutions of the present disclosure with reference to the drawings and embodiments.

[0057] Unless otherwise specified, the illustrated exemplary embodiments will be understood to provide exemplary features of various details of some ways in which the technical conceptions of the present disclosure can be implemented in practice. Thus, unless otherwise specified, the features of the various embodiments can be additionally combined, separated, interchanged, and / or rearranged without departing from the technical conceptions of the present disclosure.

[0058] In the drawings, cross-hatching and / or shading are generally used to clarify the boundaries between adjacent components. Thus, unless stated otherwise, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement regarding the specific materials, material properties, dimensions, proportions, commonality between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. Additionally, in the drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequences may be performed in an order different from that described. For example, two consecutively described processes may be performed substantially simultaneously or in an order opposite to that described. Further, the same reference numerals denote the same components.

[0059] When a component is referred to as being "on" or "above" another component, "connected to" or "coupled to" another component, the component can be directly on the other component, directly connected to or directly coupled to the other component, or there may be intervening components. However, when a component is referred to as being "directly on" another component, "directly connected to" or "directly coupled to" another component, there are no intervening components. For this reason, the term "connected" can refer to physical connection, electrical connection, etc., with or without intervening components.

[0060] For descriptive purposes, the present disclosure may use spatial relative terms such as "under", "below", "beneath", "underneath", "above", "on", "over", "upper", and "side (e.g., as in "sidewall")" to describe the relationship of one component to another (other) component as shown in the drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacturing. For example, if the device in the drawings is flipped, a component described as "under" or "beneath" another component or feature will then be positioned "above" the other component or feature. Thus, the exemplary term "under" can encompass both "above" and "below" orientations. Further, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted.

[0061] The terms used herein are for the purpose of describing particular embodiments and are not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are also intended to include the plural forms. In addition, when the terms "comprise" and / or "include" and their variants are used in this specification, it is stated that the stated features, integers, steps, operations, components, assemblies and / or groups thereof exist, but do not preclude the existence or addition of one or more other features, integers, steps, operations, components, assemblies and / or groups thereof. It should also be noted that, as used herein, the terms "substantially", "about" and other similar terms are used as approximate terms and not as terms of degree, and thus they are used to explain the inherent deviations of measured, calculated and / or provided values that would be recognized by those of ordinary skill in the art.

[0062] Before the existing intelligent toilet is regularly cleaned of the gap between the cover base and the toilet body, the toilet cover needs to be removed from the toilet body first. This process is not only cumbersome, but also for users lacking relevant experience or with weak hands-on ability, it may encounter many difficulties in disassembling and reinstalling the toilet cover, and may even cause damage to the toilet cover.

[0063] To solve the above technical problems, this embodiment provides a cover base lifting device. Refer to Figures 1 to 6 as shown in Figure 1 is a perspective view of the cover base lifting device in the first position in the embodiment, Figure 2 is a schematic view of the cover base lifting device in the first position in the embodiment, Figure 3 is a perspective view of the cover base lifting device in the second position in the embodiment, Figure 4 is a schematic view of the cover base lifting device in the second position in the embodiment, Figure 5 is an exploded view of the cover base lifting device in the embodiment, Figure 6 is a schematic diagram of the cover base lifting device provided with the first driving mechanism in the embodiment.

[0064] Refer to Figure 1 and Figure 3 As shown, this embodiment provides a cover base lifting device, which includes: a fixed seat 100, a connecting rod assembly 200, a locking mechanism 300 and a driving mechanism 400.

[0065] The fixed seat 100 is used to be installed on the toilet body and serves as the installation base for the connecting rod assembly 200, the locking mechanism 300 and the driving mechanism 400.

[0066] As Figure 2 and Figure 4As shown, the connecting rod assembly 200 is disposed at the upper end of the fixed seat 100. The connecting rod assembly 200 includes a first connecting rod 210, a second connecting rod 220, and a third connecting rod 230. The first connecting rod 210 and the second connecting rod 220 are respectively rotatably disposed at different positions of the fixed seat 100 and are both rotatably connected to the third connecting rod 230. Exemplarily, the bottom end of the first connecting rod 210 is rotatably disposed on the fixed seat 100 so that the first connecting rod 210 can rotate between a first position and a second position. The first position and the second position are sequentially arranged in the direction close to the second connecting rod 220. When the first connecting rod 210 rotates upward from the first position to the second position, a quadrilateral structure is formed among the first connecting rod 210, the second connecting rod 220, the third connecting rod 230, and the fixed seat 100 when the first connecting rod 210 is in the second position. The second connecting rod 220 is disposed at an interval from the first connecting rod 210, and its bottom end is rotatably disposed on the fixed seat 100. The third connecting rod 230 is disposed between the first connecting rod 210 and the second connecting rod 220, and its two ends are respectively rotatably connected to the top ends of the first connecting rod 210 and the second connecting rod 220. The third connecting rod 230 is used to mount the cover base. Among them, when the first connecting rod 210 rotates from the first position to the second position, the third connecting rod 230 moves upward and toward the first connecting rod 210.

[0067] The locking mechanism 300 is disposed on the fixed seat 100 and is used to fix the connecting rod assembly 200 so that the first connecting rod 210 is fixed at the first position. The locking mechanism 300 can use an existing mechanism or component having the function of locking the connecting rod assembly 200.

[0068] The driving mechanism 400 is disposed on the fixed seat 100 and is connected to the connecting rod assembly 200. When the first connecting rod 210 is released from fixation, it is used to drive the first connecting rod 210 to rotate from the first position to the second position. The driving mechanism 400 enables the first connecting rod 210 to automatically rotate from the first position to the second position after being released from fixation without manual operation.

[0069] As Figure 5 and Figure 6As shown, in the first embodiment of the driving mechanism 400, the driving mechanism 400 includes a spring 410, a slider 420, and a push rod 430. The fixed seat 100 is provided with a linear slide rail 110. The slide rail 110 can be a chute or a track assembly on the fixed seat 100. The slider 420 is slidably disposed on the slide rail 110 so that it can slide linearly along the slide rail 110. One end of the push rod 430 is rotatably connected to the slider 420, and the other end is rotatably connected to the first link 210. The spring 410 is disposed between the slider 420 and the fixed seat 100. In the first position, the spring 410 is compressed; when the fixation of the first link 210 at the first position is cancelled, the spring 410 drives the slider 420 to move along the slide rail 110 in a direction close to the first link 210 through its elastic force, and the slider 420 pushes the first link 210 to rotate towards the second position through the push rod 430; when the bottom end of the first link 210 is at the second position, a triangular structure is formed among the first link 210, the push rod 430, and the fixed seat 100. Among them, the spring 410 as a driving element can also be replaced by a pneumatic spring. The driving mechanism 400 of this embodiment uses the elastic force of the spring 410 as a driving source, combines simple mechanical structures such as the slider 420, the push rod 430, and the slide rail 110, realizes the rotation of the first link 210, has a simple structure, low cost, and high reliability, and reduces the probability of failure. At the same time, in the first position, the driving mechanism 400 can be accommodated between the first link 210 and the second link 220, reducing the overall volume.

[0070] Furthermore, as Figure 4 and Figure 5 shown, the slider 420 and the fixed seat 100 are respectively provided with a guide hole 421 and a guide post 101. Both ends of the spring 410 are respectively disposed in the guide hole 421 and the fixed seat 100, and the spring is sleeved on the guide post 101. The settings of the guide hole 421 and the guide post 101 enable the spring 410 to always maintain linear expansion and contraction, avoid the loss of elastic force or instability caused by the offset of the spring 410, and improve the transmission efficiency and stability of the driving mechanism 400.

[0071] Figure 7 It is a schematic diagram of the second driving mechanism provided in the cover base lifting device in the embodiment. In the figure, the first link of the cover base lifting device is in the second position.

[0072] Refer to Figure 7As shown, in the second embodiment of the drive mechanism 400, the drive mechanism 400 includes a torsion spring 440. The torsion spring 440 is disposed at the rotational connection of the first link 210 and / or the second link 220 with the fixed base 100. Exemplarily, the first link 210 and the second link 220 are connected to the fixed base 100 through a rotating shaft. The torsion spring 440 is sleeved on the rotating shaft, and both ends act on the fixed base 100 and the first link 210 or the second link 220 respectively. In the first position, the torsion spring 440 is compressed. When the fixation of the first link 210 at the first position is cancelled, the torsion spring 440 drives the first link 210 to rotate towards the second position through its elastic force. In this embodiment, the drive mechanism 400 uses the torsion spring 440 as the power source, and the torsion spring 440 is directly disposed at the rotational connection of the link and the fixed base 100, without occupying additional space, making the structure of the entire drive mechanism 400 more compact and suitable for installation in a toilet cover base lifting device with limited space.

[0073] Figure 8 It is a schematic diagram of the third drive mechanism provided in the cover base lifting device in the embodiment. In the figure, the first link of the cover base lifting device is in the second position.

[0074] Refer to Figure 8 As shown, in the third embodiment of the drive mechanism 400, the drive mechanism 400 includes a torsion spring 440 and a rotating rod 450. The rotating rod 450 is located between the first link 210 and the second link 220 and below the third link 230. The bottom end of the rotating rod 450 is rotatably connected to the fixed base 100, and the top end of the rotating rod 450 is rotatably connected to the third link 230. The torsion spring 440 is disposed at the rotational connection of the rotating rod 450 and the fixed base 100. In the first position, the torsion spring 440 is compressed. When the fixation of the first link 210 at the first position is cancelled, the torsion spring 440 drives the rotating rod 450 to rotate upward through its elastic force, and the rotating rod 450 drives the third link 230 to move, so as to drive the first link 210 to rotate towards the second position. In this embodiment, the drive mechanism 400 transmits the elastic force of the torsion spring 440 to the third link 230 through the rotating rod 450, and then drives the first link 210 to rotate. This transmission method is more flexible and can adapt to different installation spaces and motion requirements. At the same time, the rotating rod 450 has an auxiliary supporting effect on the third link 230.

[0075] Figure 9 It is a schematic diagram of the fourth drive mechanism provided in the cover base lifting device in the embodiment. In the figure, the first link of the cover base lifting device is in the second position.

[0076] Refer to Figure 9As shown, in the fourth embodiment of the driving mechanism 400, the driving mechanism 400 includes a torsion spring 440, a rotating rod 450, and a sliding member 460. The rotating rod 450 is located between the first connecting rod 210 and the second connecting rod 220 and below the third connecting rod 230. The bottom end of the rotating rod 450 is rotatably connected to the fixed seat 100, and the top end of the rotating rod 450 is rotatably connected to the sliding member 460. The sliding member 460 is arranged on the third connecting rod 230 and can slide along the length direction of the third connecting rod 230. Exemplarily, the sliding member 460 is a sliding block, and a suitable sliding track is arranged on the third connecting rod 230. The torsion spring 440 is arranged at the rotational connection between the rotating rod 450 and the fixed seat 100; in the first position, the torsion spring 440 is compressed; when the fixation of the first connecting rod 210 at the first position is cancelled, the torsion spring 440 drives the rotating rod 450 to rotate through elastic force, and the rotating rod 450 drives the sliding member 460 to slide on the third connecting rod 230, so that one end of the third connecting rod 230 drives the first connecting rod 210 to rotate towards the second position. The sliding of the sliding member 460 on the third connecting rod 230 makes the movement process more stable, and at the same time, the length of the rotating rod 450 and the position of the sliding member 460 on the third connecting rod 230 can be adjusted according to actual needs, so as to change the second position and meet the requirements of lifting the bases of different types of toilet covers.

[0077] Exemplarily, as the torsional elastic member, the above torsion spring can also be replaced by a spring sheet.

[0078] Figure 10 It is a perspective view of the locking mechanism of the cover base lifting device in the second position in the embodiment. Figure 11 It is a perspective view of the locking mechanism of the cover base lifting device in the first position in the embodiment.

[0079] As Figure 10 and Figure 11 As shown, in an embodiment of the locking mechanism 300, the locking mechanism 300 includes a clamping shaft 310. The second connecting rod 220 and the third connecting rod 230 are rotatably connected through the clamping shaft 310, and the fixed seat 100 is provided with a clamping groove 120; when the first connecting rod 210 is in the first position, the clamping shaft 310 is clamped in the clamping groove 120, and the rotation of the second connecting rod 220 is blocked between the clamping shaft 310 and the clamping groove 120 through frictional force, thereby fixing the first connecting rod 210 in the first position. When it is necessary to cancel the fixation, the user can manually operate, such as pushing the clamping shaft 310, to make the clamping shaft 310 disengage from the clamping groove 120.

[0080] Of course, as Figure 1 and Figure 3As shown, the locking mechanism 300 can also use an existing latch mechanism, that is, a latch 320 is provided on the fixed seat 100, and a pin hole is provided on any link of the link assembly 200. The rotation of the link is prevented by inserting the latch 320 into the pin hole, thereby fixing the link assembly 200 and fixing the first link 210 at the first position.

[0081] As Figure 1 and Figure 2 shown, in some embodiments of the toilet lid lifting device, a receiving groove 130 is provided at the upper end of the fixed seat 100. When the first link 210 is in the first position, the first link 210, the second link 220, and the driving mechanism 400 are located in the receiving groove 130. The receiving groove 130 houses the first link 210, the second link 220, and the driving mechanism 400, reducing the occupied space of the device in the non-working state and facilitating the installation and use of the toilet.

[0082] Exemplarily, the above-mentioned rotatable connection methods are all realized through a rotating shaft. For example, the first link 210 and the third link 230 are connected by a rotating shaft.

[0083] Figure 12 is a schematic diagram of the intelligent toilet in the initial state in the embodiment, Figure 13 is a schematic diagram of the intelligent toilet after the toilet lid is lifted in the embodiment.

[0084] This embodiment discloses a toilet lid. Referring to Figure 12 and Figure 13 shown, the toilet lid includes the toilet lid lifting device of any one of the above, and further includes a toilet lid base 500, and a toilet lid 510 is provided on the toilet lid base 500. The distance from the front end of the toilet lid 510 to the first link 210 is closer than the distance to the second link 220, that is, when the third link 230 rotates from the first position to the second position, it can drive the toilet lid 510 to move forward and upward towards the front end of the toilet. The way the toilet lid base 500 moves forward and upward makes it almost unnecessary to reserve space between the toilet lid base 500 and the water tank or the wall 700, greatly improving the utilization rate of the space around the intelligent toilet, and is especially suitable for small-sized bathroom or installation scenarios with high space requirements.

[0085] This embodiment discloses an intelligent toilet. Referring to Figure 12 and Figure 13 shown, the intelligent toilet includes the toilet lid of the previous embodiment, and further includes a toilet main body 600 (ceramic part). The fixed seat 100 of the toilet lid lifting device is fixedly installed on the upper surface of the toilet main body 600. Exemplarily, the toilet main body 600 is provided with an installation groove 610, and the fixed seat 100 is fixed in the installation groove 610 by bolts, so that the bottom of the toilet lid base 500 can be attached to the toilet main body 600 in the initial state.

[0086] When the cover base lifting device, toilet cover and intelligent toilet of the present application are in normal use, the cover base lifting device is in an initial state: the first link 210 is in the first position, and the entire link assembly 200 is fixed by the locking mechanism 300; under the connection of the link assembly 200, the third link 230 enables the cover base 500 to be normally installed on the toilet main body 600 to meet the daily use requirements of the toilet. When the user needs to lift the cover base and clean the gap between the base and the toilet main body 600, the locking mechanism 300 releases the fixation of the first link 210, so that the first link 210 is released from the locked first position and can rotate; then the driving mechanism 400 works. Under the action of the driving mechanism 400, the first link 210 starts to rotate from the first position to the second position. Since both ends of the third link 230 are rotatably connected to the first link 210 and the second link 220 respectively, as the first link 210 rotates, the third link 230 will be subjected to force. According to the motion principle of the link mechanism, the third link 230 will move along a trajectory of moving upward and toward the first link 210; then, the cover base 500 installed on the third link 230 is also lifted accordingly, and the cover base 500 gradually moves away from the toilet main body 600, and the gap between the two continuously increases. When the first link 210 rotates to the second position, the cover base 500 reaches the maximum lifting height. At this time, the gap between the base and the toilet main body 600 reaches the maximum, providing sufficient space for the cleaning work, and thus facilitating the user to clean the toilet main body 600. After the cleaning is completed, the control link assembly 200 and the driving mechanism 400 move in the reverse direction. When the first link 210 returns to the first position, the locking mechanism 300 fixes the first link 210 at the first position again, so that the entire link assembly 200 returns to the initial state, and the cover base 500 also closely fits on the toilet main body 600, and the toilet returns to the normal use state. Equally important, when the third link 230 rotates from the first position to the second position, it can drive the cover base 500 to move forward and upward, avoiding the cover base 500 from hitting the water tank or the wall 700 at the rear, so that almost no space needs to be reserved between the cover base 500 and the water tank or the wall 700, and it can meet the cleaning requirements of more types of intelligent toilets. It can be seen that when the cover base lifting device of the present application needs to be cleaned, the driving mechanism 400 drives the link assembly 200 to move, thereby driving the cover base 500 to lift, increasing the gap between the base and the toilet main body 600, and thus improving the convenience of cleaning.
