Description

Technical Field

[0001] This utility model relates to the field of toilet technology, and specifically designs an intelligent toilet seat buffer device. Background Technology

[0002] With the continuous development of society, smart devices are becoming increasingly common in daily life, such as smart toilets, smart dishwashers, smart sinks, and washing machines, with increasingly higher levels of automation. Among them, smart toilets, smart dishwashers, and smart sinks all feature automatic lid-opening functions. Existing technologies also include drive-driven lid-opening buffers, which mainly include a drive motor, an elastic element, and a limiting platform. The drive motor connected to the lid rotates and presses the elastic element, generating sufficient friction to buffer the toilet seat. There are also electrically driven lid-opening buffers, which mainly include a lid-opening gearbox. They generally achieve automatic lid opening and closing through a control board that drives the motor, and work with a potentiometer component for sensing and detection. However, if the potentiometer component malfunctions or does not work, the toilet seat fixed to the output shaft will not be able to open after it is in position. Continuous output from the drive motor will cause a short circuit and damage to the drive motor, affecting the user experience and operating costs. Utility Model Content

Detailed Implementation

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] like Figure 1-9 As shown, a smart toilet seat 3 buffer device includes a drive motor 1, a reduction mechanism 2, a seat 3, and an internal gear ring 4. The seat 3 includes a mounting cover 301 and an end cover 302. The drive motor 1 is disposed on one side of the mounting cover 301. The internal gear ring 4 is disposed between the mounting cover 301 and the end cover 302. The reduction mechanism 2 is disposed in the inner cavity of the internal gear ring 4. One end of the internal gear ring 4 is disposed on the other side of the mounting cover 301, and the other end of the internal gear ring 4 is disposed on one side of the end cover 302. A mounting groove 303 is provided on one side of the plate 301, and a motor output gear 304 is provided in the mounting groove 303. A speed change shaft 5 is provided on one side of the mounting groove 303. A central shaft 6 is provided above the speed change shaft 5. The reduction mechanism 2 includes an overload protection gear set 201 and a planetary gear 202. The overload protection gear set 201 and the planetary gear 202 are sequentially arranged on the central shaft 6 to prevent the drive motor 1 from locking up and continuously outputting, which could cause the drive motor 1 to short circuit or even be damaged, thereby improving the user experience and reducing the cost of use.

[0024] Furthermore, the overload protection gear set 201 is disposed above the motor output gear 304. The overload protection gear set 201 includes a large gear 2011 and a small gear 2012. The small gear 2012 is disposed on the central shaft 6. One end of the small gear 2012 is provided with a mounting end 2013, and the other end is provided with a drive gear 2014. The large gear 2011 is disposed on the mounting end 2013, and its outer side is provided with a transmission tooth 2015, which is adapted to the motor output gear 304. A connecting spring 2016 is provided between the large gear 2011 and the mounting end 2013 to adjust the speed ratio and increase the torque so that the drive motor 1 outputs stably.

[0025] Additionally, a slot 2017 is provided on one side of the large gear 2011. The slot 2017 is adapted to the connecting spring 2016. The connecting spring 2016 is interference-fitted with the small gear 2012 to ensure the connection strength between the connecting spring 2016 and the small gear 2012. One side of the connecting spring 2016 is locked in the overload protection gear set 201, and the other side is interference-fitted with the small gear 2012. During the operation of the drive motor 1, if an external force forces the toilet seat to move in the opposite direction, the connecting spring 2016 is locked in the slot of the overload protection gear set 201, and the drive motor 1 continues to output power from behind, so that the connecting spring 2016 is under continuous tension. The force of the connecting spring 2016 locking the small gear 2012 gradually loosens, so that the small gear 2012 rotates in the connecting spring 2016. This can prevent the drive motor 1 from locking up and avoid short circuits or damage to the drive motor 1.

[0026] Furthermore, a speed-changing gear 203 is provided between the overload protection gear set 201 and the planetary gear 202. The speed-changing gear 203 is mounted on the speed-changing shaft 5. The speed-changing gear 203 includes a large tooth portion 2031 and a small tooth portion 2032, which are integrally formed. The large tooth portion 2031 is connected to the drive gear 2014, and the small tooth portion 2032 is connected to the input end of the planetary gear 202 to adjust the speed ratio at the output end of the motor and increase the output torque of the drive motor 1.

[0027] Additionally, the output end of the planetary gear 202 is provided with an output shaft 7, and a potentiometer gear 8 is provided between the output shaft 7 and the planetary gear 202; below the potentiometer gear 8 is a potentiometer assembly 9, which can sense and detect the flip angle of the toilet seat 3 to ensure that the toilet seat 3 is flipped into place.

[0028] Furthermore, the end cover 302 is provided with an output shaft 7 mounting hole 10 to improve the installation stability of the output shaft 7.

[0029] In addition, the drive motor 1 is equipped with a cover 11 to prevent the drive motor 1 from being damaged by external forces.

[0030] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
