[0002] At present, the toilet seats of most common toilets (including those used at home, in shopping malls, and on public transportation) are manually opened and closed. Affected by the purpose of the toilet and hygienic factors, especially in public places with large flow of people and complex personnel, some men dislike the trouble and dirt of bending over and touching the back-lifting toilet seat (or side-lifting toilet seat) with their hands, so it is common to urinate without lifting the toilet seat. This kind of uncivilized phenomenon will cause urine and feces contamination of the toilet seat, affecting the subsequent toilet hygiene of women and people who defecate. In the use of ordinary household toilets, there is also the problem of bending over and manually opening and closing the toilet seat with the back being troublesome and affecting hand hygiene. Therefore, a hygienic non-hand-contact toilet seat opening and closing device has strong practical value.

[0003] Although some electric toilets can electrically control the opening and closing of the toilet seat, they are expensive and cannot be widely used in ordinary households and public places. Ordinary toilets are standardized and mature products produced in large quantities. The production of each part has standard size drawings and corresponding casting molds. If the installation of the non-hand-contact toilet seat opening and closing device affects the structure of the existing toilet, it will cause a significant change in the toilet production drawings and molds, resulting in the problem of redesigning drawings, changing molds, and changing production lines, which will affect the normal production of toilet companies.

[0004] Therefore, inventing a non-hand-contact convenient installation toilet seat opening and closing device without changing the external structure of the existing toilet is a practical solution. At the same time, the external dimensions of toilets of different brands are different. Therefore, the new toilet seat opening and closing device also needs to be universal for toilets of different external dimensions. Summary of the invention

It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, not all.

[0035] See also Figure 1-Figure 6 , this embodiment provides a universal and easy-to-install foot-operated toilet seat opening and closing device.

[0036] The present invention is mainly composed of a toilet seat ring connector 2, an opening and closing action transmission connecting rod module 3, a foot-operated pedal opening and closing and limiting module 4, a base fixing module 5, etc., wherein 1 is a toilet seat ring, such as Figure 1 The device is installed on the outer side of an ordinary toilet bowl, does not affect any structure of the original toilet bowl, and can be installed on both sides.

[0037] like Figure 3 As shown, one side of the toilet seat connector 2 is a connecting block 203 with rounded corners (to increase the bonding area), and its flat glue uses the bonding principle to achieve a firm bonding between the toilet seat connector 2 and the bottom surface of the toilet seat 1; the other side of the toilet seat connector 2 is a shaft with a groove, which is inserted into the hole of the upper connecting rod 301 in the opening and closing action transmission connecting rod module 3, and after positioning, the retaining spring 202 is clamped in the groove to fix the toilet seat connector 2 and the upper connecting rod 301; the opening and closing of the toilet seat 1 can be achieved by swinging the upper connecting rod 301;

[0038] The opening and closing action transmission connecting rod module 3 is a two-link mechanism; the upper connecting rod 301 has two cylindrical holes, and the aperture thereof is equal to the diameter of the small shaft of the toilet seat ring connecting piece 2; the middle hole needs to be coaxial with the rotating shaft of the toilet seat ring 1 during installation, and this is used as the reference for the front and rear installation positions of the entire device; the swing of the upper connecting rod 301 is realized by pulling the lower connecting rod; the lower connecting rod is an outer sleeve of two retractable sleeves, and the height of toilet seats of different sizes can be adapted by adjusting its length; the upper end of the outer sleeve 302 is hinged to the upper connecting rod 301, and a threaded hole is opened at the lower end; the inner sleeve 303 can be freely retracted at the lower part of the outer sleeve 302, and when the retractable length is adjusted, the inner sleeve 303 can be locked by a screw 304 to determine the overall length of the lower connecting rod; the lower connecting rod is hinged to the pedal 405 of the foot-operated pedal opening and closing and limit module 4, and the rotation of the pedal 405 can drive the lower connecting rod to pull the upper connecting rod 301.

[0039] like Figure 1 , 4As shown in Figures 5 and 6, the foot-operated pedal opening and closing and limiting module 4 is composed of a side plate 401, a threaded stop pin 402, a torsion spring 403, a bottom plate 404 and a foot pedal 405. The bottom plate 404 is a flat plate with four left-right symmetrical through holes and four threaded holes to accommodate the installation of the side plate 401 on either side of the left or right side thereof. The side plate 401 is a T-shaped plate with two through holes on each side of the horizontal plate, which is fastened to the two threaded holes on one side of the bottom plate 404 by screws and two through holes on one side; the vertical plate is provided with a vertical through slot and a horizontal through slot. The lower end of the foot pedal 405 is hinged to the front end of the bottom plate 404, and relative rotation with the bottom plate 404 is achieved by stepping on it, driving the lower connecting rod to move downward. The upper end of the foot pedal 405 is provided with two hooks 406 symmetrically distributed on the left and right sides. After stepping on it, it hooks the horizontal groove 407 on the side plate 401 to prevent the foot pedal 405 from rebounding after the foot is released. A torsion spring 403 is installed between the foot pedal 405 and the bottom plate 404. After urinating, the sole of the foot lightly steps on the foot pedal 405 again and moves outward. After the hook is separated from the horizontal groove 407, the torsion spring 403 can bounce the foot pedal 405 up and drive the lower connecting rod to rise. In order to limit the rebound stroke of the foot pedal 405, a threaded stop pin 402 is inserted into the vertical through groove of the vertical plate to limit the limit position of the foot pedal 405 rebounding. After the limit position is determined, the nut on the stop pin 402 is locked.

[0040] like Figure 1 , 7 As shown, the base fixing module 5 is composed of 4 suction cups with shafts. The suction cups are sucked on the ground, and the suction cup shafts are provided with threads. The suction cup shafts pass through the 4 holes in the middle of the bottom plate 404 and are clamped with nuts to achieve the fixing of the bottom plate 404 and the entire device on the ground.

[0041] When the device can only be installed on the left side of the toilet due to space limitations in the bathroom, it is only necessary to install the toilet seat connector 2 and the side plate 401 upside down. Figure 6 shown.

[0042] Installation steps:

[0043] (1) Place the torsion spring 403 and the foot pedal 405 on the bottom plate 404. Figure 1 After the relationship is shown, the upper connecting rod 301, the outer sleeve 302, the inner sleeve 303, and the screw 304 are installed as shown in FIG. Figure 1 The relationship shown is installed.

[0044] (2) Determine whether the device is on the left or right side of the toilet bowl based on the location of the toilet bowl and the space available in the bathroom.

[0050] (8) The positional relationship between the outer sleeve 302 and the inner sleeve 303 is adjusted, and the length of the sleeve is adjusted so that the suction cup contacts the ground to adapt to the external dimensions of toilet bowls of different specifications.

[0051] (9) Expel the air from the suction cup so that the foot-operated pedal opening and closing and limit module 4 is fastened to the ground.

[0052] (10) Step on the foot pedal 405, adjust the upper limit position of the threaded stop pin 402 on the side plate 401 according to the opening angle of the toilet seat 1, and lock the stop pin 402 with a nut.

[0053] When the device can only be installed on the left side of the toilet due to space limitations in the bathroom, it is only necessary to install the toilet seat connector 2 and the side plate 401 upside down. Figure 6 shown.

[0054] Steps:

[0055] (1) When a man urinates, he steps on the foot pedal 405, which causes a series of components behind it to work together, and the toilet seat 1 gradually opens. At the same time, the hook on the foot pedal 405 can hook into the horizontal groove of the vertical plate 401 during the downward rotation process, maintaining the final open state of the toilet seat 1.

[0056] (2) Men urinate with their legs tucked in.

[0057] (3) After a man urinates or the next person to use the toilet seat 1 steps on the foot pedal 405 and slightly moves his foot outward to drive the hook on the foot pedal 405 to disengage from the horizontal groove of the vertical plate 401.

[0058] (4) After the foot is retracted, the torsion spring 403 can bounce the foot pedal 405, and a series of components behind it are linked to make the toilet seat 1 fall back and lay flat. At the same time, the stop pin 402 can limit the upper limit position of the foot pedal 405.

[0059] (5) Repeat this process to realize the hygienic and convenient opening and closing of the toilet seat 1 by foot-operated operation.
