Description

Technical Field

[0001] This utility model generally relates to the field of bathroom equipment technology, and more specifically, to a smart toilet seat lifting structure and a toilet. Background Technology

[0002] Currently, most smart toilet seats on the market are fixed to the ceramic surface with bolts. While this installation method is relatively stable, problems arise when cleaning the toilet ceramic.

[0003] When cleaning the ceramic part of the toilet bowl, you'll find that the rear half of the ceramic end face is obscured by the fixed seat. To thoroughly clean this area, lifting the smart seat is necessary. However, this lifting operation is extremely cumbersome; users must manually remove and lift the seat, a complex process that is too difficult for the average user. Therefore, during daily cleaning, most users simply give up on cleaning the obscured area. Over time, this area easily becomes a breeding ground for mold and dust, affecting both the toilet's appearance and threatening the user's health due to bacterial growth.

[0004] 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. Utility Model Content

[0040] like Figures 1-5As shown, this embodiment provides a lid lifting structure for a smart toilet, including: a lid 100 that is detachably and fixedly connected or movably connected to a toilet base 200; a lifting device for lifting the lid 100 is provided on the toilet base 200; the lifting device includes a supporting main component 300; the supporting main component 300 is provided with a driving device 400, a relatively movable toothed column 500, and a guide structure 310; the driving device 400 drives the toothed column 500 to achieve relative lifting and lowering movement; the guide structure 310 is used to limit the relative movement direction of the driving device 400 and the toothed column 500; when lifting the lid 100, the supporting main component 300 and the toilet base 200 remain relatively stationary, and the toothed column 500 drives the lid 100 to rise; or the toothed column 500 and the toilet base 200 remain relatively stationary, and the supporting main component 300 drives the lid 100 to rise. Under normal circumstances, the toilet seat 100 is mounted on the toilet base 200. The detachable connection between the toilet seat 100 and the toilet base 200 can be via insertion, snap-fit, magnetic attraction, or bolt locking. Movable connections can be via a guide rail structure or a hinged structure. Therefore, when needed, the toilet seat 100 can be temporarily lifted and separated from the toilet base 200. The toilet seat 100 can be used to cover the internal structure of the toilet, including but not limited to covering the toilet bowl. The toilet seat 100 can also serve as a carrier for the main functional components of the smart toilet, including but not limited to functions such as lid opening, closing, flushing, bidet, heating, and drying. A control device electrically connected to and controlling the drive unit 400 can also be located therein, allowing the motor 410 of the drive unit 400 to operate manually or remotely, performing forward or reverse rotation. In this embodiment, the toilet seat 100 includes a front cover integrating functional components and a rear cover for covering the toilet bowl. The guide structure 310 is mainly used to guide the gear column 500 or the main support component 300 to move relatively vertically, so as to lift the lid 100. In this embodiment, the main support component 300 is fixedly connected to the toilet base 200 or detachably connected to maintain relative stillness. When lifting the lid 100, the motor 410 of the main support component 300 drives the gear column 500 to rise and push the lid 100 on its upper side to rise, thus completing the lifting of the lid 100. When the output of the gearbox 430 reaches the preset time, the gearbox 430 switches to short-circuiting the positive and negative poles of the motor 410. At this time, the gearbox 430 generates an electromagnetic torque to provide support force for the lid 100, thereby maintaining the lid 100 in a raised and suspended state. The descent of the lid 100 can be achieved by connecting the lid 100 to the gear column 500 and driving the gear column 500 and the lid 100 to descend by reversing the motor 410. Alternatively, after the motor 410 drives the toothed column 500 to descend, the cover plate 100 can be lowered by its own weight or by manually pressing down on the cover plate 100.In other embodiments, the toothed column 500 is fixed to the toilet base 200 and remains relatively stationary. When the lid 100 is lifted, the drive gear 420 of the motor 410 rotates and climbs upward along the toothed column 500, causing the integrated support main component 300 to rise and driving the lid 100 to rise. In this embodiment, the support main component 300 is provided on the rib plate of the toilet base 200.

[0041] In some embodiments, such as Figures 1-2 As shown, the main support component 300 is detachably and fixedly connected to the toilet base 200. The driving device 400 includes a motor 410, and the output shaft of the motor 410 is equipped with a drive gear 420. The gear 500 meshes with the drive gear 420, and the gear 500 moves along the direction defined by the guide structure 310 under the drive of the drive gear 420, thereby causing the cover plate 100 to rise. It can be understood that the detachable connection between the main support component 300 and the toilet base 200 can be a snap-fit ​​type, a magnetic type, a bolt fastening type, etc. This detachable structure facilitates the production and manufacturing of components such as the main support component 300, is easy to install and replace, and has high design flexibility. In this embodiment, the direction defined by the guide structure 310 is the vertical direction, that is, under the restriction of the guide structure 310, the gear 500 can only move up and down.

[0042] In some embodiments, such as Figures 1-2 As shown, a travel limiting structure 600 is included to limit the lifting stroke of the cover plate 100. It is understood that the travel limiting structure 600 prevents the gear column 500 or the cover plate 100 from moving excessively beyond a safe range, thus preventing equipment damage. This can be a mechanical limit, an electronic limit, or similar mechanism. The mechanical limit principle could involve causing the gear column 500 or the motor 410 to encounter motion resistance, resulting in increased current or overheating. The overload protection unit in the motor 410 would then quickly cut off the power supply to the motor 410 or reduce its output power. Simultaneously, the motor 410, such as a stepper motor or a servo motor with a brake, would automatically lock its rotor, keeping the gear column 500 at the raised height.

[0043] In some embodiments, such as Figures 1-2As shown, the stroke limiting structure 600 includes a limiting pin 610 on the main support component 300 and a long limiting groove 620 on the gear column 500. One end of the limiting pin 610 is fitted into the long limiting groove 620 and is used to limit the lifting stroke of the gear column 500. It can be understood that when the gear column 500 rises, the long limiting groove 620 moves upward, and the limiting pin 610 remains relatively stationary with the main support component 300. When the lower part of the long limiting groove 620 rises to the point of colliding with the limiting pin 610, it is blocked by the limiting pin 610, thus creating a mechanical limiting effect. The motor 410 no longer drives the gear column 500 to rise, and the gear column 500 remains at the rising height. Conversely, when the motor 410 is controlled to run in the opposite direction by the control device, and the gear column 500 descends, the upper part of the long limiting groove 620 collides with the limiting pin 610, triggering the mechanical limiting.

[0044] In some embodiments, such as Figures 1-2 As shown, the guide structure 310 includes a first guide channel 311 disposed on the main support component 300, and a toothed post 500 disposed within the first guide channel 311. The first guide channel 311 has a threaded hole 312, and the limiting pin 610 has a threaded portion 611 for screwing into the threaded hole 312. It can be understood that the detachable structure of the limiting pin 610 allows for easy installation of the toothed post 500 into the first guide channel 311, followed by the fitting of the limiting pin 610 into the long limiting groove 620.

[0045] In some embodiments, such as Figure 1 As shown, the main support component 300 is provided with a mounting chamber 320, and the motor 410 is disposed within the mounting chamber 320. The mounting chamber 320 has a through hole communicating with the first guide channel 311. The output shaft of the motor 410 passes through the through hole, extends into the first guide channel 311, and is connected to the gear column 500 for transmission. It can be understood that the mounting chamber 320 can effectively and conveniently fix the motor 410. In this embodiment, a sealing cover 321 is provided at the opening of the mounting chamber 320. After the motor 410 is installed into the mounting chamber 320 through the opening, the sealing cover 321 is used to close the chamber, ensuring the airtightness of the mounting chamber 320 and protecting the motor 410. In some embodiments, the motor 410 is also provided with a gearbox 430. In this case, the size of the mounting chamber 320 can be adjusted accordingly to accommodate the motor 410 and its gearbox 430 as a whole.

[0046] In some embodiments, such as Figures 1-2As shown, the main support component 300 is provided with a second guide channel 330, and a guide post 800 is provided within the second guide channel 330. The guide post 800 supports the cover plate or is detachably fixedly connected to the cover plate 100. It is understood that, in order to make the cover plate 100 more stable during lifting and prevent swaying, and to fix the position of the cover plate 100 during use, a guide post 800 is provided between the cover plate 100 and the toilet base 200 to form a guide rail structure. The upper end of the guide post 800 is connected to the cover plate 100. For example, a cap 810 is provided at the upper end of the guide post 800, and the cap 810 has several connecting holes for locking with the cover plate 100. The number of second guide channels 330 and guide posts 800 is not limited and can be adjusted according to actual conditions. In this embodiment, there are two second guide channels 330, respectively located on both sides of the first guide channel 311, and the first guide channel 311 and the toothed post 500 are located near the center of gravity of the cover plate 100.

[0047] In some embodiments, such as Figures 1-2 As shown, the second guide channel 330 has a threaded cylindrical surface 331 on its outer periphery. The threaded cylindrical surface 331 passes through the toilet base 200 and is locked to the toilet base 200 by a nut 710. It can be understood that the method of locking the main support component 300 to the toilet base 200 via the second guide channel 330 is not only convenient to install but also provides high stability. In this embodiment, a flat washer 720 and a plastic washer 730 are also provided on one side of the nut 710 on the second guide channel 330 to provide protection, leveling, insulation, and cushioning.

[0048] In some embodiments, such as Figure 1 As shown, the upper end of the toothed column 500 is provided with a support portion 510 for expanding the support surface, and the support portion 510 is located on the lower side of the cover plate 100. It can be understood that the support portion 510 can disperse the pressure of the toothed column 500 on the cover plate 100, protect the cover plate 100, and at the same time increase the contact surface, making the lifting process more stable.

[0049] like Figures 3-5 As shown, this embodiment provides a toilet, including a lid lifting structure of a smart toilet as described in any of the preceding claims. The toilet base 200 includes a toilet bowl 210 and an installation cavity 220 located at the rear of the toilet bowl. The lifting device is located in the installation cavity 220. The lid 100 includes a fixed seat and an upper cover and seat ring that can rotate relative to the fixed seat. The lifting device lifts the fixed seat and thus lifts the lid 100, so that at least the portion of the lid 100 with the fixed seat is separated from the toilet base 200.

[0050] It should be understood that the various examples described above can be utilized in multiple directions (e.g., tilted, inverted, horizontal, vertical, etc.) and in multiple configurations without departing from the principles of this invention. The embodiments shown in the accompanying drawings are merely examples of effective application of the principles of this invention, and the invention is not limited to any specific details of these embodiments.

[0051] Of course, upon careful consideration of the above description of the representative embodiments, those skilled in the art will readily understand that various modifications, additions, substitutions, deletions, and other changes can be made to these specific embodiments, and that such changes are within the scope of the principles of this invention. Therefore, the foregoing detailed description should be clearly understood as being given by way of illustration and example only, and the spirit and scope of this invention are defined solely by the appended claims and their equivalents.
