AI Technical Summary
Existing capacitive sensor flip-top toilets are too slow to flip up in emergency situations, causing inconvenience for users.
When a capacitive sensor detects a user approaching, the drive motor quickly flips the two-piece toilet seat via a pulley system, utilizing the two-piece design to reduce resistance and achieve rapid opening.
The ability to quickly prepare the toilet seat in an emergency avoids delays in the opening and closing process, improving ease of use and hygiene.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of toilet technology, specifically a capacitive foot-activated flip-top flush toilet. Background Technology
[0002] Currently, some flip-top toilets on the market utilize capacitive sensing technology. These toilets use capacitive sensors to detect the user's approach, automatically triggering the flip-top mechanism. The working principle of the capacitive sensor is that when a user approaches the toilet, the sensor detects a change in the electric field of the human body and sends a signal to activate the flip-top mechanism of the toilet seat.
[0003] The advantage of this type of toilet is that it eliminates the need for manual operation through sensor technology, improving both convenience and hygiene. Users do not need to touch the toilet seat, reducing the risk of bacterial transmission through contact and enhancing the hygienic experience. Capacitive sensor flip-top toilets are widely used in public places, smart homes, and high-end products, providing a more intelligent and comfortable user experience.
[0004] However, existing designs still face some challenges, especially for the need to open quickly in emergency situations. Many capacitive sensor flip-top toilets may lag in the speed of opening, especially when users need to use the toilet quickly, the opening process may be too slow, causing inconvenience to users. To address this, we propose a capacitive foot-activated flip-top flushing toilet. Utility Model Content

[0006] Furthermore, the first and second parts are respectively provided with a first connecting ear and a second connecting ear on opposite sides, the second connecting ear is fixedly connected to a rotating shaft, and the first connecting ear is rotatably connected to the rotating shaft.
[0007] Furthermore, both the first and second parts have openings on opposite sides, the first part has a cavity, a drive motor is installed in the cavity, a first pulley is fixedly connected to the output end of the drive motor, a second pulley is fixedly connected to the shaft, and a belt connects the first pulley and the second pulley.
[0008] Furthermore, the toilet body is equipped with a flip-top device for flipping the toilet seat, and the capacitive sensor, the flip-top device, and the drive motor are electrically connected.
[0009] Compared with the prior art, the beneficial effects of this utility model are:
[0010] This invention's quick-folding mechanism solves the problem of users needing to use the toilet quickly in emergency situations, while avoiding the delays in opening traditional toilet seats, ensuring that the toilet seat can be quickly prepared for use. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0017] Depend on Figure 1-3 The present invention includes a toilet body 1, a capacitive sensor 2 is provided at the lower end of the side wall of the toilet body 1, the sensing end of the capacitive sensor 2 is exposed outside the toilet body 1, and a foldable toilet seat 3 is provided at the top of the toilet body 1. The toilet seat 3 includes a first part 4 and a second part 5.
[0018] The first part 4 and the second part 5 are respectively provided with a first connecting ear 402 and a second connecting ear 501 on opposite sides. The second connecting ear 501 is fixedly connected to the rotating shaft 8, and the first connecting ear 402 is rotatably connected to the rotating shaft 8.
[0019] The first split body 4 and the second split body 5 each have an opening on their opposite sides. The first split body 4 has a cavity 401 inside. A drive motor 6 is installed inside the cavity 401. A first pulley 7 is fixedly connected to the output end of the drive motor 6. A second pulley 9 is fixedly connected to the rotating shaft 8. A belt 10 connects the first pulley 7 and the second pulley 9.
[0020] The toilet body 1 is equipped with a flip-top device for flipping the toilet seat 3. The capacitive sensor 2, the flip-top device and the drive motor 6 are electrically connected.
[0021] Working principle: When a user approaches the toilet, the capacitive sensor 2 senses the signal of the human body approaching and immediately sends a signal to the drive motor 6. The drive motor 6 drives the second pulley 9 through the first pulley 7 at its output end, thereby driving the rotating shaft 8 to rotate. Since the first split body 4 and the second split body 5 are connected by the rotating shaft 8, this drive allows the toilet seat 3 to fold quickly. The advantage of the folding design is that, through the split method, the toilet seat will encounter less resistance when opening, thus opening at a higher speed and reducing the user's waiting time.
[0022] This quick-folding mechanism solves the problem of users needing to use the toilet quickly in emergencies, while avoiding the delays in opening traditional toilet seats, ensuring that the toilet seat can be quickly prepared for use.
