Description

Technical Field

[0001] This application relates to the field of bathroom fixtures, and in particular to a toilet seat base lifting device and a smart toilet. Background Technology

[0002] In modern home life, smart toilets have greatly improved people's quality of life with their convenient, comfortable, and intelligent functions. Current smart toilets mainly consist of a ceramic toilet body and a toilet seat. The toilet seat includes a lid, seat ring, body assembly, and seat base. The seat base serves as the mounting carrier for the lid, seat ring, and body assembly, and is installed on the toilet body using a specific fixing method.

[0003] However, due to the gap between the toilet seat base and the toilet body, water stains, dust, hair and other impurities will inevitably enter the gap during daily use. Over time, these impurities will gradually accumulate, not only affecting the overall aesthetics of the bathroom, but more seriously, they will breed a large number of bacteria and odors, affecting the user's health and user experience.

[0004] To maintain a clean and healthy bathroom, users need to regularly clean the gap between the toilet seat base and the toilet body. However, current cleaning methods are quite inconvenient. Before cleaning, users usually need to remove the toilet seat from the toilet body. This process is not only tedious, but for users lacking relevant experience or with weak hands-on skills, disassembling and reinstalling the toilet seat may present many difficulties, and may even lead to damage to the toilet seat.

[0005] Therefore, how to design a new type of smart toilet seat base installation structure that can conveniently and quickly clean the gap between the base and the toilet body to avoid dirt accumulation has become a technical problem that urgently needs to be solved in this field.

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

[0007] (a) Technical problems to be solved

[0008] This application provides a toilet seat base lifting device, a toilet seat, 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 Solution

[0010] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0011] One aspect provides a cover plate base lifting device, the cover plate base lifting device comprising:

[0012] Mounting bracket, used for mounting on the toilet body;

[0013] A linkage assembly is disposed on the upper end of the fixed base. The linkage assembly includes a first link, a second link, and a third link. The first link and the second link are rotatably disposed at different positions on the fixed base and are rotatably connected to the third link. The first link can rotate between a first position and a second position. The first link rotates upward from the first position to the second position.

[0014] A locking mechanism is provided on the fixed base and is used to fix the connecting rod assembly so that the first connecting rod is fixed in the first position;

[0015] A drive mechanism is disposed on the fixed base and connected to the linkage assembly, used to drive the first linkage to rotate from the first position to the second position when the first position is unfixed;

[0016] The third link is used to install the cover plate base. When the first link rotates from the first position to the second position, the third link moves obliquely upward.

[0017] In some embodiments of the cover plate 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 between the first connecting rod, the push rod, and the fixed seat.

[0018] In the first position, the driving element includes an elastic element that is compressed; when the first link is unfixed in the first position, the elastic element of the driving element drives the slider to move along the slide rail toward the first link by elastic force, and the slider moves to push the push rod, thereby causing the first link to rotate toward the second position.

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

[0020] In some embodiments of the cover plate base lifting device, the driving mechanism includes a torsional elastic element disposed at the rotatable connection between the first link and / or the second link and the fixed seat; in the first position, the torsional elastic element is compressed; when the first link is unfixed in the first position, the torsional elastic element drives the first link to rotate to the second position by elastic force.

[0021] In some embodiments of the cover plate base lifting device, the driving mechanism includes a torsional elastic element and a rotating rod. The rotating rod is located between the first and second connecting rods and below the third connecting rod. The bottom end of the rotating rod is rotatably connected to a fixed seat, and the top end of the rotating rod is rotatably connected to the third connecting rod. The torsional elastic element is disposed at the rotatable connection between the rotating rod and the fixed seat. In the first position, the torsional elastic element is compressed. When the first connecting rod is unfixed in the first position, the torsional elastic element drives the rotating rod to rotate upward through elastic force. The rotating rod drives the third connecting rod to move, so that the first connecting rod rotates to the second position.

[0022] In some embodiments of the cover plate base lifting device, the driving mechanism includes a torsional elastic element, a rotating rod, and a sliding element. The rotating rod is located between the first and second connecting rods and below the third connecting rod. The bottom end of the rotating rod is rotatably connected to a fixed seat, and the top end of the rotating rod is rotatably connected to the sliding element. The sliding element is disposed on the third connecting rod and can slide along the length of the third connecting rod. The torsional elastic element is disposed at the rotatable connection between the rotating rod and the fixed seat. In the first position, the torsional elastic element is compressed. When the first connecting rod is unfixed in the first position, the torsional elastic element drives the rotating rod to rotate through elastic force. The rotating rod drives the sliding element to slide on the third connecting rod, so that one end of the third connecting rod and the first connecting rod rotate to the second position.

[0023] In some embodiments of the cover plate base lifting device, the locking mechanism includes a locking shaft, the second connecting rod and the third connecting rod are rotatably connected by the locking shaft, and the fixed seat is provided with a locking groove; when the first connecting rod is in the first position, the locking shaft is locked in the locking 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, and when the first connecting rod is in the first position, the first connecting rod, the second connecting rod and the driving mechanism are located in the receiving groove.

[0025] On the other hand, a toilet seat is disclosed, which includes the seat base lifting device described in any of the above-mentioned claims, and also includes a seat base, on which a seat plate is provided. The distance from the front end of the seat plate to the first connecting rod is closer to the distance to the second connecting rod. When the first connecting rod is in the first position, the seat plate base is attached to the fixed seat. When the first connecting rod is in the second position, the seat plate base is lifted by the seat base lifting device.

[0026] On another front, a smart toilet is disclosed, which includes the aforementioned toilet seat and a toilet body, with the fixing seat of the seat base lifting device fixedly installed on the toilet body.

[0027] (III) Beneficial Effects

[0028] Compared with the prior art, the beneficial effects of the technical solution provided in this application include at least the following:

[0029] In normal use, the seat base lifting device, toilet seat, and smart toilet of this application are in the initial state: the first connecting rod is in the first position, and the entire connecting rod assembly is fixed by the locking mechanism; the third connecting rod, under the connection of the connecting rod assembly, allows the seat base to be normally installed on the toilet body to meet the needs of daily toilet use. When the user needs to clean the gap between the base and the toilet body, the locking mechanism releases the first link, allowing it to rotate freely from its locked first position. The drive mechanism then operates, causing the first link to rotate from the first position to the second position. Since the two ends of the third link are rotatably connected to the first and second links respectively, the third link experiences a force as the first link rotates. According to the motion principle of the linkage mechanism, the third link moves upwards and towards the first link. Next, the seat base mounted on the third link is also lifted, gradually moving away from the toilet body, increasing the gap between them. When the first link rotates to the second position, the seat base reaches its maximum height, maximizing the gap between the base and the toilet body, providing ample space for cleaning and facilitating user cleaning of the toilet body. After cleaning, the control linkage assembly and drive mechanism move in the opposite direction. When the first linkage returns to the first position, the locking mechanism fixes the first linkage in the first position again, so that the entire linkage assembly returns to its initial state, and the seat base also fits tightly against the toilet body, and the toilet returns to normal use.

[0030] Equally important, when the third link rotates from the first position to the second position, it can move the seat base forward and upward, preventing the seat base from hitting the water tank or wall behind it. This means that there is almost no space to be reserved between the seat base and the water tank or wall, making it suitable for the cleaning needs of more types of smart toilets.

[0031] As can be seen, the seat base lifting device of this application drives the linkage assembly to move through the drive mechanism when cleaning is required, thereby lifting the seat base, increasing the gap between the base and the toilet body, and thus improving the convenience of cleaning.

[0054] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0055] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0056] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0057] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0058] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, 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 "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0060] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying 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 manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0061] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, 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 rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0062] Before users can regularly clean the gap between the seat base and the toilet body, existing smart toilets require the toilet seat to be removed from the toilet body. This process is not only cumbersome, but also presents many difficulties for users who lack relevant experience or have weak hands-on skills. It may even lead to damage to the toilet seat.

[0063] To address the aforementioned technical problems, this embodiment provides a cover plate base lifting device. (See reference...) Figures 1 to 6 As shown, Figure 1 This is a perspective view of the cover plate base lifting device in the first position in the embodiment. Figure 2 This is a schematic diagram of the cover plate base lifting device in the first position in the embodiment. Figure 3 This is a perspective view of the cover plate base lifting device in the second position in the embodiment. Figure 4 This is a schematic diagram of the cover plate base lifting device in the second position in the embodiment. Figure 5 This is an exploded view of the cover plate base lifting device in the embodiment. Figure 6 This is a schematic diagram of the first type of drive mechanism installed in the cover plate base lifting device in the embodiment.

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

[0065] The mounting base 100 is used to install on the toilet body as the mounting base for the linkage assembly 200, the locking mechanism 300 and the drive mechanism 400.

[0066] like Figure 2 and Figure 4As shown, the linkage assembly 200 is disposed on the upper end of the fixed base 100. The linkage assembly 200 includes a first link 210, a second link 220 and a third link 230. The first link 210 and the second link 220 are rotatably disposed at different positions of the fixed base 100 and are rotatably connected to the third link 230. For example, the bottom end of the first link 210 is rotatably disposed on the fixed base 100 so that the first link 210 can rotate between a first position and a second position. The first position and the second position are arranged sequentially along the direction close to the second link 220. The first link 210 rotates upward from the first position to the second position. When the first link 210 is in the second position, the first link 210, the second link 220, the third link 230 and the fixed base 100 form a quadrilateral structure. The second link 220 is spaced apart from the first link 210, and its bottom end is rotatably mounted on the fixed base 100. The third link 230 is disposed between the first link 210 and the second link 220, and its two ends are rotatably connected to the top ends of the first link 210 and the second link 220, respectively. The third link 230 is used to install the cover plate base. When the first link 210 rotates from the first position to the second position, the third link 230 moves upward and toward the first link 210.

[0067] The locking mechanism 300 is disposed on the fixed base 100 and is used to fix the linkage assembly 200 so that the first linkage 210 is fixed in a first position. The locking mechanism 300 can use existing mechanisms or components that have the function of locking the linkage assembly 200.

[0068] A drive mechanism 400 is mounted on the fixed base 100 and connected to the linkage assembly 200. It drives the first linkage 210 to rotate from the first position to the second position when the first position is released from its fixed position. The drive mechanism 400 allows the first linkage 210 to automatically rotate from the first position to the second position after the fixed position is released, without manual operation.

[0069] like Figure 5 and Figure 6As shown, in the first embodiment of the drive mechanism 400, the drive mechanism 400 includes a spring 410, a slider 420 and a push rod 430. The fixed base 100 is provided with a linear slide rail 110. The slide rail 110 can be a groove or track assembly on the fixed base 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 connecting rod 210. The spring 410 is disposed between the slider 420 and the fixed base 100. In the first position, spring 410 is compressed. When the first link 210 is released from the first position, spring 410 drives slider 420 to move along slide rail 110 towards the first link 210 via its elastic force. Slider 420 pushes the first link 210 to rotate to the second position via push rod 430. When the bottom end of the first link 210 is in the second position, a triangular structure is formed between the first link 210, push rod 430, and fixed base 100. Spring 410 can also be replaced with a pneumatic spring as the driving element. The driving mechanism 400 of this embodiment utilizes the elastic force of spring 410 as the driving source, combined with simple mechanical structures such as slider 420, push rod 430, and slide rail 110, to achieve the rotation of the first link 210. The structure is simple, low-cost, and highly reliable, reducing the probability of failure. Furthermore, in the first position, the driving mechanism 400 can be housed between the first link 210 and the second link 220, reducing the overall volume.

[0070] Furthermore, such as Figure 4 and Figure 5 As shown, the slider 420 and the fixed base 100 are respectively provided with guide holes 421 and guide posts 101. The two ends of the spring 410 are respectively provided in the guide holes 421 and the fixed base 100, and the spring is sleeved on the guide posts 101. The arrangement of the guide holes 421 and guide posts 101 ensures that the spring 410 always maintains linear extension and contraction, avoiding the loss of elastic force or instability caused by the spring 410 deflection, and improving the transmission efficiency and stability of the drive mechanism 400.

[0071] Figure 7 This is a schematic diagram of the second drive mechanism installed in the cover plate base lifting device in the embodiment. In the diagram, the first connecting rod of the cover plate base lifting device is in the second position.

[0072] See Figure 7As shown, in a second embodiment of the drive mechanism 400, the drive mechanism 400 includes a torsion spring 440. The torsion spring 440 is disposed at the rotatable connection between the first connecting rod 210 and / or the second connecting rod 220 and the fixed seat 100. For example, the first connecting rod 210 and the second connecting rod 220 are connected to the fixed seat 100 via a rotating shaft. The torsion spring 440 is sleeved on the rotating shaft, and its two ends act on the fixed seat 100 and the first connecting rod 210 or the second connecting rod 220, respectively. In the first position, the torsion spring 440 is compressed. When the first connecting rod 210 is released from the first position, the torsion spring 440 drives the first connecting rod 210 to rotate to the second position through its elastic force. In this embodiment, the drive mechanism 400 uses the torsion spring 440 as a power source. The torsion spring 440 is directly disposed at the rotatable connection between the connecting rod and the fixed seat 100, without occupying additional space, making the structure of the entire drive mechanism 400 more compact and suitable for installation in toilet seat base lifting devices with limited space.

[0073] Figure 8 This is a schematic diagram of the third driving mechanism in the cover plate base lifting device of the embodiment. In the diagram, the first connecting rod of the cover plate base lifting device is in the second position.

[0074] See 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 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 base 100, and the top end of the rotating rod 450 is rotatably connected to the third connecting rod 230. The torsion spring 440 is disposed at the rotatable connection between the rotating rod 450 and the fixed base 100. In the first position, the torsion spring 440 is compressed. When the first connecting rod 210 is released from the first position, the torsion spring 440 drives the rotating rod 450 to rotate upward through its elastic force. The rotating rod 450 drives the third connecting rod 230 to move, so that the first connecting rod 210 rotates to the second position. In this embodiment, the drive mechanism 400 transmits the elastic force of the torsion spring 440 to the third link 230 via the rotating rod 450, thereby driving 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 provides auxiliary support for the third link 230.

[0075] Figure 9 This is a schematic diagram of the fourth type of drive mechanism in the cover plate base lifting device of the embodiment. In the diagram, the first connecting rod of the cover plate base lifting device is in the second position.

[0076] See Figure 9As shown, in the fourth embodiment of the drive mechanism 400, the drive 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 base 100, and the top end of the rotating rod 450 is rotatably connected to the sliding member 460. The sliding member 460 is disposed on the third connecting rod 230 and can slide along the length direction of the third connecting rod 230. For example, the sliding member 460 is a sliding block, and a suitable sliding track is provided on the third connecting rod 230. A torsion spring 440 is located at the rotatable connection between the rotating rod 450 and the fixed base 100. In the first position, the torsion spring 440 is compressed. When the first connecting rod 210 is released from its first position, the torsion spring 440 drives the rotating rod 450 to rotate via its elastic force. The rotating rod 450 causes the sliding member 460 to slide on the third connecting rod 230, thereby causing one end of the third connecting rod 230 and 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. 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, thereby changing the second position to adapt to the lifting requirements of different types of toilet seat bases.

[0077] For example, the torsion spring described above, as a torsional elastic element, can also be replaced by a spring sheet.

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

[0079] like Figure 10 and Figure 11 As shown, in one embodiment of the locking mechanism 300, the locking mechanism 300 includes a retaining shaft 310. The second connecting rod 220 and the third connecting rod 230 are rotatably connected via the retaining shaft 310, and the fixing base 100 is provided with a retaining groove 120. When the first connecting rod 210 is in the first position, the retaining shaft 310 is engaged in the retaining groove 120. Friction between the retaining shaft 310 and the retaining groove 120 prevents the second connecting rod 220 from rotating, thereby fixing the first connecting rod 210 in the first position. When it is necessary to release the fixation, the user can manually operate, such as pushing the retaining shaft 310, to disengage the retaining shaft 310 from the retaining groove 120.

[0080] Of course, such as Figure 1 and Figure 3As shown, the locking mechanism 300 can also use an existing pin mechanism, that is, a pin 320 is provided on the fixed base 100, and a pin hole is provided on any link of the link assembly 200. The pin 320 is inserted into the pin hole to prevent the link from rotating, thereby fixing the link assembly 200 and fixing the first link 210 in the first position.

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

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

[0083] Figure 12 This is a schematic diagram of the smart toilet in its initial state in the embodiment. Figure 13 This is a schematic diagram of the smart toilet seat after it is raised in the embodiment.

[0084] This embodiment discloses a toilet seat, see reference. Figure 12 and Figure 13 As shown, the toilet seat includes the seat base lifting device mentioned above, and also includes a seat base 500, on which a seat 510 is mounted. The distance from the front end of the seat 510 to the first connecting rod 210 is approximately the same as the distance to the second connecting rod 220. That is, when the third connecting rod 230 rotates from the first position to the second position, it can move the seat 510 towards the front of the toilet and upward. The forward and upward movement of the seat base 500 eliminates the need for pre-reserved space between the seat base 500 and the water tank or wall 700, greatly improving the utilization rate of the space around the smart toilet, making it especially suitable for small bathrooms or installation scenarios with high space requirements.

[0085] This embodiment discloses a smart toilet, see reference. Figure 12 and Figure 13 As shown, the smart toilet includes the toilet seat of the previous embodiment and a toilet body 600 (ceramic part). The fixing seat 100 of the seat base lifting device is fixedly installed on the upper surface of the toilet body 600. For example, the toilet body 600 is provided with a mounting groove 610, and the fixing seat 100 is fixed in the mounting groove 610 by bolts, so that the bottom of the seat base 500 can fit against the toilet body 600 in the initial state.

[0086] In normal use, the toilet seat base lifting device, toilet seat, and smart toilet of this application are in their initial state: the first connecting rod 210 is in the first position, and the entire connecting rod assembly 200 is fixed by the locking mechanism 300; the third connecting rod 230, connected by the connecting rod assembly 200, allows the toilet seat base 500 to be normally installed on the toilet body 600 to meet the needs of daily toilet use. When the user needs to lift the toilet seat base and clean the gap between the base and the toilet body 600, the locking mechanism 300 releases the first connecting rod 210, allowing it to rotate from the locked first position; subsequently, the drive mechanism 400 operates, and under the action of the drive mechanism 400, the first connecting rod 210 begins to rotate from the first position to the second position. Since the two ends of the third connecting rod 230 are rotatably connected to the first connecting rod 210 and the second connecting rod 220 respectively, the third connecting rod 230 will be subjected to force as the first connecting rod 210 rotates. According to the motion principle of the linkage mechanism, the third linkage 230 moves upward and towards the first linkage 210. Then, the seat base 500 mounted on the third linkage 230 is also lifted, gradually moving away from the toilet body 600, increasing the gap between them. When the first linkage 210 rotates to the second position, the seat base 500 reaches its maximum lifting height, at which point the gap between the base and the toilet body 600 reaches its maximum, providing ample space for cleaning and facilitating user cleaning of the toilet body 600. After cleaning, the control linkage assembly 200 and drive mechanism 400 reverse their movements. When the first linkage 210 returns to the first position, the locking mechanism 300 fixes the first linkage 210 back in the first position, restoring the entire linkage assembly 200 to its initial state. The seat base 500 also fits tightly against the toilet body 600, and the toilet returns to normal use. Equally important, when the third link 230 rotates from the first position to the second position, it can move the seat base 500 forward and upward, preventing the seat base 500 from hitting the water tank or wall 700 behind it. This eliminates the need for a space between the seat base 500 and the water tank or wall 700, making it suitable for the cleaning needs of more types of smart toilets. It can be seen that the seat base lifting device of this application drives the link assembly 200 to move via the drive mechanism 400 when cleaning is required, thereby lifting the seat base 500 and increasing the gap between the base and the toilet body 600, thus improving the convenience of cleaning.
