[0002] In recent decades, China's economy has developed comprehensively and achieved brilliant achievements. In the process of development, some phenomena and problems have also emerged and received widespread attention. For example, with the implementation of the national two-child policy, there will be more pregnant women. With the continuous improvement of the quality of life, this group of pregnant women pays more and more attention to prenatal and postnatal care and safety. It is very inconvenient for pregnant women to use toilets, and it is difficult to squat. At the same time, because the toilet is usually slippery, it is also extremely unsafe. Speaking of the problem of the expansion of the aging population in my country, there will be a large number of aging people in the future. Due to their age, this group of people is in poor physical condition. It is difficult to go to the toilet when they are inconvenient in the waist and legs.

[0029] See also Figures 1 to 5 As shown, the functional seat 2 includes a washlet assembly 22 and an arm assist device 21 integrally fixed to the washlet assembly 22. The washlet assembly 22 includes a base assembly 221, a washlet module 222 assembled and carried on the base assembly 221, and a remote control assembly 23. The base assembly 221 includes a base plate 2211, a lower fastener 2212, and an upper cover plate 2213. The base plate 2211 includes a bearing portion 2201 for bearing the washlet module 222, and a support portion 2202 integrally connected to the left and right side edges of the bearing portion 2201. The support portion 2202 includes a vertical portion 2203 connected to the left and right side edges of the bearing portion 2201 and a horizontal portion 2204 connected to the upper end edge of the vertical portion 2203, and the horizontal portion 2204 and the bearing portion 2201 are located on the left and right sides of the vertical portion 2203.

[0030] Looking directly at the base plate 2211, the support portion 2202 is lower than the horizontal portion 2204. When the washlet module 222 is assembled on the base assembly 221 (actually supported on the support portion 2202), the bearing seat ring 2220 of the washlet module 222 is flush with (or substantially flush with) the horizontal portion 2204. The arm assist device 21 is actually an angled handrail (actually preferably a 90-degree "L"-shaped handrail) for providing handholding for the user. An arm assist device 21 is fixed on each side of the washlet assembly 22.

[0031] See also Figures 2 to 7, the height adjustment assembly 3 includes an arc-shaped sliding rod 31 and a linear motor assembly 32. The inner wall of the support seat 1 is formed with an arc-shaped slide rail 15 having an arc-shaped track. One end (lower end position) of the arc-shaped sliding rod 31 is slidably connected to the arc-shaped slide rail 15 through a connecting member 5. In the present application, the connecting member 5 is a bolt member, and the connecting member 5 passes through the lower end of the arc-shaped sliding rod 31 in the left-right direction and is fixed to a limit plate (not shown, not marked). The limit plate corresponds to the sliding limit cooperation with the arc-shaped slide rail 15. Of course, the connecting member 5 can also be designed in the form of a pin (not shown) or a bearing (not shown), and it is only necessary to satisfy that one end of the arc-shaped sliding rod 31 can slide in the arc-shaped slide rail 15 along the arc-shaped track of the arc-shaped slide rail 15.

[0032] The other end (upper end) of the arc-shaped sliding rod 31 passes through the through hole 13 and is fixed integrally with the base assembly 221. Specifically, the lower fastener 2212 is fixed to the upper edge of the arc-shaped sliding rod 31, the horizontal portion 2204 of the base plate 2211 is correspondingly supported on the upper portion of the lower fastener 2212, and the upper cover plate 2213 is correspondingly covered on the upper portion of the horizontal portion 2204. The lower fastener 2212, the horizontal portion 2204 and the upper cover plate 2213 are stacked in the up-down direction and fixed integrally by bolts. The lower fastener 2212 is formed with a downwardly bent fixed leg 2210, and the upper end of the arc-shaped sliding rod 31 is fixed integrally with the fixed leg 2210 by bolts or pins.

[0033] Please refer to Figure 2 , Figure 4 and Figure 5 As shown, in the present application, the support seat 1 is further provided with a roller component 16 at a position below the through hole 13 and in front and behind the arc-shaped sliding rod 31. The sliding rod 31 is in rolling contact with the roller component 16. The roller component 16 is used to limit the sliding trajectory of the arc-shaped sliding rod 31 and make the arc-shaped sliding rod 31 slide smoothly.

[0034] See also Figures 2 to 7, the linear motor assembly 32 includes a motor 321 and a lifting rod (marked) linked to the motor 321. The lifting rod can realize up and down movement under the drive of the motor 321 (the linear motor is a prior art, and its operating principle is not repeated). One end of the lifting rod is linked with one end of the arc-shaped sliding rod 31 (in this design, it is the upper end of the arc-shaped sliding rod 31) through a pin (not marked) (of course, in other embodiments, one end of the lifting rod can also be linked with the functional seat 2). The lower end of the linear motor assembly 32 (actually a certain position of the motor 321) is rotatably connected to the support seat 1 through a pin (not shown). The fool-proof toilet auxiliary lifting device shown in this application also includes a battery assembly (not shown) assembled in the support seat 1, and the battery assembly 6 is used to power the motor 321 of the linear motor assembly 32, and the remote control assembly 23 is used to control the operation of the motor 321.

[0035] In this design, the washlet module 222 is a mature product in the industry, which can integrate toilet cover heating, warm water washing, warm air drying, and sterilization. Through microcomputer control, comfortable and hygienic, and humanized, this application will not elaborate too much. The washlet module 222 is supported and installed on the bearing part 2201 and is located between the two support parts 2202. The upper surface of the base plate 2211 is designed to fit with the bearing seat ring 2221 of the washlet module 222, and is used to stably bear the bearing seat ring 2221.

[0036] Please refer to Figures 2 to 7 As shown, the foolproof toilet auxiliary lifting device of the present application also includes a switch module 4 fixed in the support seat 1. The switch module 4 is fixed at the lower position of the arc-shaped sliding rod 31. The switch module 4 is a contact switch, including a cantilevered switch arm 41, and the switch module 4 is opened or closed by swinging the free end of the switch arm 41 upward or downward. The downward swing of the switch arm 41 is realized by the arc-shaped sliding rod 31 pressing down and enabling deformation, and the upward swing of the switch arm 41 is realized by its own resilience. The switch module 4 is connected to the power input terminal of the washlet module 222. In the present application, the washlet module 222 is equipped with a remote control device 2222, and the remote control device is used to remotely control the washlet module 222 to realize functions. When the switch module 4 is closed, the Washlet module 222 can realize normal functions (mainly referring to the functions of toilet cover heating, warm water washing, warm air drying, sterilization, etc.), and when the switch module 4 is disconnected, the Washlet module 222 loses its function.

[0037] The foolproof toilet auxiliary lifting device of this application realizes its designed function according to the following actuation mode:

[0038] The user turns his back to the foolproof toilet auxiliary lifting device, with his buttocks leaning against the load-bearing seat ring 2221 of the Washlet module 222; the linear motor assembly 32 is controlled by the remote control assembly 23 (of course, in other embodiments, for ease of use, a remote control assembly or switch for controlling the linear motor assembly 32 can also be set near the armrest position of the arm assisting device 21); the arm assisting device 21 is held with both hands; and the lifting rod is controlled to descend or ascend; the descent or ascent of the lifting rod will drive the arc-shaped sliding rod 31 to descend or, because the arc-shaped sliding rod is constrained by the arc-shaped slide rail 15, the through hole 13 and the roller component 16, the arc-shaped sliding rod 31 will descend or ascend along the arc-shaped trajectory of the arc-shaped slide rail 15, and thus drive the functional seat 2 to descend or ascend. The user can terminate the movement of the linear motor assembly 32 at any time through the remote control assembly 23 to achieve the functional seat 2 to be stationary at a specific angle to meet the user's toilet needs.

[0039] When the linear motor assembly 32 drives the functional seat 2 to move downward to the lowest position, that is, when the bearing seat ring 2221 of the washlet module 222 is in a horizontal position, the lower end of the arc-shaped sliding rod 31 presses down the switch arm 41 of the switch module 4 and drives the switch arm 41 to swing downward. At this time, the switch module 4 is in a closed state, and the washlet module 222 can function normally. When the linear motor assembly 32 drives the functional seat 2 to move upward to any position (except the lowest position), the switch arm 41 rebounds upward. At this time, the switch module 4 is in a disconnected state, and the washlet module 222 cannot function normally. The arc-shaped sliding rod 31 drives the switch module 4 to open and close, and then controls the function of the washlet module 222, which plays a fool-proof role and prevents the washlet module 222 from working when the bearing seat ring 2221 is in a tilted position. If the load-bearing seat ring 2221 is in an inclined position, the washlet module 222 may start to work, which may result in inadequate flushing or misalignment, causing the risk of leakage or electric shock, and may also make the user feel uncomfortable and cause safety hazards (such as unnecessary dodging or movement of the human body causing falls, etc.).

[0040] In addition, in order to take into account the user's comfort, safety, and the overall performance stability of the foolproof toilet auxiliary lifting device during use, after repeated experimental verification, this design has made size design limitations on the important structures of the foolproof toilet auxiliary lifting device, their positional relationships, movement angles, and movement amounts, etc., and the specific reference is as follows:

[0041] Please refer to Figure 6As shown, when the functional seat 2 moves downward to the lowest position, that is, when the bearing seat ring 2221 of the washlet module 222 is in a horizontal position, the distance between the front edge of the washlet assembly 22 and the front edge of the support seat 1 is H1, and H1 is not less than 70 mm and not more than 90 mm (preferably 81 mm in this design). The arm assist device 21 is formed with a gripping portion 211 for the user's hand to grasp, and the gripping portion 211 is located directly above the front edge of the washlet assembly 22. In this application, along the front-to-back direction, the front edge of the arm assist device 21 does not extend forward beyond the front edge of the support seat 1.

[0042] Please refer to Figure 7 As shown, when the functional seat 2 moves upward from the lowest position to the highest position, the front end edge of the load-bearing seat ring 2221 of the Washlet module 222 rises to a height of H2 (not marked in the figure), and H2 is not less than 110 mm and not more than 150 mm. In this design, H2 is preferably 134 mm.

[0043] Please refer to Figure 7 As shown, when the functional seat 2 moves upward from the lowest position to the highest position, the angle of inclination of the bearing seat ring 2221 of the washlet module 222 from the horizontal state to the inclined state is B, and the angle B is not less than 20 degrees and not more than 70 degrees. The preferred range of the angle B in this design is not less than 25 degrees and not more than 45 degrees.

[0044] Please refer to Figure 6 and Figure 7 As shown, when the functional seat 2 is at the highest position, the front end edge of the bearing seat ring 2221 is at position B1 ( Figure 7 As shown, not marked), when the functional seat 2 is at the lowest position, the front edge of the load-bearing seat ring 2221 is at position B2 ( Figure 6 , not marked). Along the front-to-back direction, the position B1 is located behind B2. And in this design, the displacement from B1 to B2 along the front-to-back direction is not less than 5 mm and not more than 35 mm. Specifically, in this application, when the functional seat 2 is located at the highest position, the distance between the front edge of the load-bearing seat ring 2221 and the front edge of the support seat 1 is 104 mm. When the functional seat 2 is located at the low-height position, the distance between the front edge of the load-bearing seat ring 2221 and the front edge of the support seat 1 is 81 mm.

[0045] In addition, in an ideal state, the center of the arc-shaped sliding rod 31 of the present design is actually the user's knee position. Due to differences in human body shape, the specific position of the center of the circle cannot be determined in practice, but after repeated sampling experiments, the radius of the circle where the arc-shaped sliding rod 31 is located is designed to be not less than 450 mm and not more than 550 mm. In the present design, the radius of the circle where the arc-shaped sliding rod 31 is located is preferably 500 mm.

[0046] The above dimensions, spacings, angles and other values ​​are obtained by the applicant based on multiple sampling of normal human body shapes (height between 140 cm and 200 cm) and numerous experimental verifications. Within the above dimensions, spacings, angles and other value ranges, the entire fool-proof toilet auxiliary lifting equipment is stable in use and has high safety performance. After repeated sampling and use verification, users have good feedback on the use experience and high comfort.

[0047] It should be noted that the rotational connection through pins defined in this article is not limited to pins, and can be other rotational connections, such as bearings.
