[0018] The beneficial effects of this utility model are as follows: This utility model provides a toilet base lifting device, which, compared with the prior art, has at least the following technical effects: 1. A lifting guide component is provided, which includes a lifting drive component, or a lifting drive component and a linear guide component. The lifting drive component provides a power source to lift the base, allowing the base to be separated from the upper surface of the toilet body. This avoids the problem of the contact area being difficult to clean due to traditional screw fixing, making it easier to clean the contact area. Furthermore, the lifting guide component is distributed at the front and rear of the base to guide the base's lifting and lowering, ensuring accurate repositioning after lifting. This solution can provide a power source for lifting the base and provide guidance by setting lifting drive components at both the front and rear, or by setting a combination of lifting drive component and linear guide component to provide a power source for lifting the base and guide its lifting and lowering, ensuring accurate repositioning after lifting. 2. The linear guide component, through the cooperation of guide column and guide sleeve, ensures that the base can accurately reposition and prevents the base from shaking during lifting and lowering. 3. The guide sleeve and bracket are integrated, allowing for one-time installation onto the toilet body, improving production efficiency. Multiple guide sleeves provide multiple fixing points, ensuring a more secure connection between the bracket and the toilet body. Alternatively, the guide sleeve and bracket can be detached, allowing them to be fixed together before installing the bracket into the toilet body, further improving assembly efficiency. 4. Separate installation of the linear guide assembly and lifting drive assembly facilitates maintenance and reduces repair costs. 5. The limiting assembly consists of a lifting stop and a limiting drive. The limiting drive drives the lifting assembly to unlock or lock, limiting the base and preventing accidental lifting, thus improving the user experience. 6. A limiting boss on the base or toilet body, engaging with the limiting slider, restricts the base's lifting, preventing accidental lifting. 7. The actuating slider pushes against the first inclined plane via the second inclined plane, displacing the limiting slider and thus unlocking or locking the base, thereby limiting its lifting. 8. Multiple sets of lifting guide components drive the base to rise, allowing the base to separate from the upper surface of the toilet body. This avoids the problem of the contact area being difficult to clean due to traditional screw fixation, facilitating cleaning of the contact area. Simultaneously, the multiple sets of lifting guide components also drive the base to accurately rise and fall, preventing displacement. 9. Three sets of lifting guide components ensure more even force distribution, enabling horizontal lifting of the base. This helps reduce wear on the piston cylinder and piston rod. Furthermore, the fixing of the piston cylinder to the toilet body and the piston rod to the base reduces displacement deviation during use. 10. Threads are provided on the piston cylinder surface for easy fixing of the piston cylinder to the toilet body. A retaining ring is provided between the piston rod and the connecting cylinder of the rear lifting drive component, ensuring a secure interference fit. Attached Figure Description

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1:

[0037] Please see Figures 1 to 8 A toilet base lifting device includes a toilet body 1 and a base 2 disposed on the toilet body 1, and further includes:

[0038] A lifting guide assembly is disposed between the toilet body 1 and the base 2, and is pulsatorically connected to the base 2. At least one lifting guide assembly is connected to the front and rear portions of the base 2, respectively. The lifting guide assembly includes a lifting drive assembly 3, or alternatively, it includes a lifting drive assembly 3 and a linear guide assembly 4.

[0039] A lifting drive assembly 3 is disposed between the toilet body 1 and the base 2. The lifting drive assembly 3 is connected to the base 2 in a transmission manner and has a power source to drive the base 2 to lift relative to the toilet body 1.

[0040] A linear guide assembly 4 is connected between the toilet body 1 and the base 2, and is used to guide the lifting and lowering of the base 2. This can be achieved by providing a lifting drive assembly 3 at both the front and rear, which provides both power for lifting the base 2 and provides guidance; or by combining the lifting drive assembly 3 and the linear guide assembly 4, both power and guidance for lifting the base 2 can be achieved, ensuring accurate repositioning after lifting.

[0041] Please see Figures 1 to 6In this embodiment, the lifting guide assembly includes a lifting drive assembly 3 and two linear guide assemblies 4. The lifting drive assembly 3 is located in the middle of the rear side of the base, and the two linear guide assemblies 4 are located on the front and rear sides of the base, forming a triangular distribution that distributes the force more evenly and avoids wear on a single tilted side. Preferably, each set of linear guide assemblies 4 includes a guide post 42 and a guide sleeve 41. The guide post 42 is installed on the toilet body 1, and the guide sleeve 41 is installed on the base 2; or, the guide post 42 is installed on the base 2, and the guide sleeve 41 is installed on the toilet body 1. The guide post 42 passes through the guide sleeve 41 and can slide relative to the guide sleeve 41. The linear guide assembly 4, through the cooperation of the guide post 42 and the guide sleeve 41, ensures that the base 2 can accurately return to its original position and prevents the base 2 from shaking during lifting.

[0042] Please see Figures 1 to 6 Preferably, the lifting drive assembly 3 includes a piston cylinder, and the toilet body 1 also includes a bracket 5. The bracket 5 has a mating groove, the cylinder end of the piston cylinder is fixedly connected to the bottom surface of the base 2, and the piston rod of the piston cylinder is connected to the mating groove. The guide sleeve 41 is disposed on the bracket 5 and integrally formed with the bracket 5. The outer circumference of the guide sleeve 41 is threaded, and a nut 8 is inserted to lock the bracket 5 in the toilet body 1. The guide post 42 is fixedly connected to the bottom of the base 2. The guide sleeve 41 and the bracket 5 are integrally set, so the bracket 5 and the guide sleeve 41 can be installed on the toilet body 1 in one go, which helps to improve production efficiency. Moreover, multiple guide sleeves 41 can provide multiple fixing points, making the connection between the bracket 5 and the toilet body 1 more secure. Other embodiments can also adopt the method that the guide sleeve and the bracket are detachable, so that the bracket and the guide sleeve can be fixed together before the bracket is installed into the toilet body, which helps to improve assembly efficiency.

[0043] Please see Figures 4 to 8 Preferably, the device further includes a limiting component 6, which comprises a lifting blocking member 61 and a limiting drive member 62. The lifting blocking member 61 is disposed between the toilet body 1 and the base 2, and the limiting drive member 62 is pulsatorically connected to the lifting blocking member 61. The limiting drive member 62 drives the lifting blocking member 61 to block the lifting and lowering of the base 2. The limiting component 6 consists of the lifting blocking member 61 and the limiting drive member 62 working together. The limiting drive member 62 drives the lifting component to unlock or lock, thereby limiting the base 2 and preventing the user from accidentally lifting the base 2 during use, thus improving the user experience.

[0044] Please see Figures 4 to 8Preferably, the limiting component 6 further includes a housing 63, the lifting blocking component 61 is a limiting slider, and the limiting driving component 62 is a starting slider. The limiting slider and the starting slider are slidably installed in the housing 63. The housing 63 is fixedly connected to the base 2, and the toilet base 2 is provided with a limiting boss 7; or, the housing 63 is fixed in the toilet body 1, and the base 2 is provided with a limiting boss 7; the limiting slider can protrude from the housing 63 and cooperate with the limiting boss 7 to achieve limiting. By providing a limiting boss 7 on the base 2 or the toilet body 1 to cooperate with the limiting slider, the limiting boss 7 abuts against the limiting slider, which can limit the lifting of the base 2 to prevent the base 2 from being accidentally raised.

[0045] Please see Figures 4 to 8 Preferably, the limiting slider is provided with a first protrusion 611 having a first inclined surface, and the starting slider is provided with a second protrusion 621 having a second inclined surface. The first and second inclined surfaces are in a pushing-pushing fit. The starting slider is driven by an external force to push the limiting slider out of or retract into the housing 63. A first reset member 64 is provided between the limiting slider and the housing 63 to drive the limiting slider to reset, and a second reset member 65 is provided between the starting slider and the housing 63 to drive the starting slider to reset, so that the limiting slider retracts into or protrudes from the housing 63. The starting slider is driven to move by tension. Since the starting slider is inclined, the movement of the second inclined surface will push against the first inclined surface. The limiting slider is subjected to the force transmitted by the second inclined surface, which overcomes the force of the first reset member 64 and moves into the housing 63, thereby disengaging from the limiting protrusion 7 and releasing the limiting surface. Figure 7 As shown in Figure B, the lifting drive assembly 3 can drive the base 2 to rise. Removing the force of the pull rope on the starting slider, the second reset component 65 drives the starting slider to reset, and the first reset component 64 drives the limit slider to reset. The limit slider can then protrude from the housing 63 again and contact the limit boss 7 for limiting. The first reset component 64 and the second reset component 65 can be springs, rubber rings, etc., and are not limited to these. The surface of the limit slider that mates with the limit boss 7 when the base 2 descends is designed as an inclined surface. During descent, the force from the limit boss 7 pushes the limit slider back into the housing 63. Simultaneously, the limit slider also pushes the starting slider to move, avoiding obstructing the descent of the base 2 and ensuring that the base 2 can reset smoothly. When the limit slider passes the limit boss 7, the first reset component 64 drives the limit slider to reset, and the second reset component 65 drives the starting slider to reset, restoring the state of limiting the base 2 to rise. Figure 7 As shown in Figure A, a limiting block 66 protruding into the first sliding groove is also installed on the housing 63, and the limiting slider is provided with a matching limiting groove to prevent the limiting slider from dislodging from the first sliding groove; the movement directions of the starting slider and the limiting slider in the housing 63 are perpendicular to each other.

[0046] Please see Figures 1 to 8 Preferably, the piston cylinder moves the piston rod by injecting fluid, thus raising or lowering the base 2. The piston cylinder can be a pneumatic cylinder or a hydraulic cylinder. If it is a pneumatic cylinder, gas is injected into the cylinder's inner tank via an air pump to drive the piston rod. If it is a hydraulic cylinder, municipal water is introduced into the cylinder via a water pump or an elastic accumulator to drive the piston rod. The elastic accumulator can be installed on a toilet seat or toilet bowl. The elastic accumulator stores or releases energy by pressing, thus raising or lowering the base 2.

[0047] This embodiment has the following working principle:

[0048] When it is necessary to clean the contact surface between the base 2 and the toilet body 1, the slider is activated by the button connected to the pull cord. The second inclined surface pushes against the first inclined surface to drive the limit slider to move back into the housing 63 and release the limit boss 7. At the same time, the piston rod of the lifting drive assembly 3 (the piston cylinder is driven by fluid, and the control of the fluid can be linked with the pull cord) extends to lift the base 2, so that the base 2 drives the guide column 42 to move upward along the axis of the guide sleeve 41, thus cleaning the contact surface between the base 2 and the toilet body 1. After cleaning, the lifting drive assembly 3 descends, and the base 2 descends under its own weight. Under the guidance of the guide column 42 and the guide sleeve 41, the base 2 returns to the initial contact position with the toilet body 1.

[0049] Example 2

[0050] Please see Figures 9 to 10 The difference between this embodiment and Embodiment 1 is that: the toilet body 1 is provided with a connecting ear 11, the guide sleeve 41 is fixed in the connecting ear 11, the toilet body 1 is also provided with an installation hole, the piston cylinder is fixed in the installation hole, the guide column 42 is fixedly connected to the base 2, the base 2 is provided with a connecting hole 21, the piston rod of the piston cylinder passes through the connecting hole 21, and a retaining ring 9 is also fitted on the piston rod; the linear guide assembly 4 and the lifting drive assembly 3 are installed separately, which facilitates maintenance and reduces maintenance costs. The working principle of this embodiment is the same as that of Embodiment 1.

[0051] Example 3

[0052] Please see Figures 11 to 14The difference between this embodiment of the toilet base lifting device and the first embodiment is that the lifting guide assembly in this embodiment includes multiple sets of lifting drive assemblies 3. These multiple sets of lifting drive assemblies 3 are spaced apart between the toilet body 1 and the base 2, with one end fixedly connected to the toilet body 1 and the other end fixedly connected to the base 2. The arrangement of multiple sets of lifting drive assemblies 3 drives the base 2 to lift, allowing the base 2 to be separated from the upper surface of the toilet body 1. This avoids the problem of the contact area being difficult to clean due to traditional screw fixing, thus facilitating cleaning of the contact area. Simultaneously, the distribution of multiple sets of lifting drive assemblies 3 also enables the base 2 to accurately rise or precisely descend and reset, avoiding unilateral wear caused by uneven load during displacement.

[0053] Please see Figures 11 to 14 Preferably, the lifting drive assembly 3 consists of three groups arranged in a triangular pattern; each lifting drive group includes a piston cylinder and a piston rod, the piston cylinder being fixed to the toilet body 1 and the piston rod being fixed to the base 2. The presence of three groups of lifting drive assemblies ensures more even force distribution, enabling the base 2 to be raised and lowered horizontally. This helps reduce wear on the piston cylinder and piston rod. Furthermore, the fixing of the piston cylinder to the toilet body 1 and the piston rod to the base 2 reduces displacement deviations during use.

[0054] Please see Figures 11 to 14 Preferably, the outer circumferential surface of the piston cylinder body is threaded, and a nut 8 passes through the outer circumferential surface of the piston cylinder body. A connecting lug 11 is provided on each of the two sides of the front portion of the toilet body 1 where the base 2 is installed. The connecting lug 11 has a mounting hole, and the piston cylinder is placed in the mounting hole. The nut 8 engages with the thread on the outer circumferential surface of the piston cylinder to fix the piston cylinder body onto the connecting lug 11. The piston rods of these two sets of lifting drive assemblies 3 are locked to the base 2 by screws. Another mounting hole is provided in the middle of the rear portion of the toilet body 1 where the base 2 is installed. The cylinder body of the remaining set of piston cylinders of the lifting drive assembly 3 is placed in this mounting hole. A retaining ring 9 is provided on the piston rod of the lifting drive assembly 3. A connecting hole 21 is provided at a corresponding position on the base 2. The piston rod of the lifting drive assembly 3 passes through the connecting hole 21, and the retaining ring 9 is positioned between the connecting hole 21 and the piston rod. At least one set of piston cylinders in the lifting drive assembly 3 is a hydraulic cylinder. The piston cylinder has threads on its surface to facilitate its fixation to the toilet body 1. A retaining ring 9 is provided between the piston rod and the connecting cylinder of the rear lifting drive assembly 3, ensuring a secure interference fit. A pressure relief port is provided on the piston cylinder or pipeline of the lifting drive assembly 3. Opening the pressure relief port allows the pressure relief base 2 to fall and fit against the toilet body 1. The cylinder itself has a guiding function, thus keeping the base 2 horizontal during lifting and lowering, maintaining even force, and preventing unilateral wear caused by tilting.

[0055] The working principle of this utility model is as follows:

[0056] When it is necessary to clean the contact surface between the base 2 and the toilet body 1, fluid is simultaneously injected into the piston cylinders of the three sets of lifting drive components 3, and the piston rods will then push upwards to lift the base 2. Figure 14 As shown; after cleaning, the piston cylinder is depressurized, and the base 2 descends and resets under its own weight, as indicated. Figure 13 As shown.
