[0052] Embodiment 1:

[0053] Compared with the original design, this embodiment is a manual mode, and the difference lies in the design of the transmission mechanism. The transmission mechanism includes a transmission arm 36, and the sealing plate shaft 35 is symmetrically connected to the transmission arm 36 on both sides. The center of the transmission arm 36 is connected to a universal shaft 14, and the universal shaft 14 is connected to a movable shaft 39 through a connecting rod 15, and a spring 12 is installed on the connecting rod 15.

[0054] One side of the movable shaft 1 39 is connected to the fixed shaft 1 37 through a transmission lever 38, and the other side is connected to the movable shaft 2 40 and the movable shaft 3 41 in sequence. A fixed bracket 42 serving as a fixed fulcrum is installed under the movable shaft 3 41, and the other side of the movable shaft 3 41 is connected to the pedal 45 through the pedal connecting rod 44.

[0055] The movable shaft 3 41 is connected to a fixing bolt 48 via a support rod 47 , and the fixing bolt 48 is installed on the baffle.

[0056] A plurality of spring leaves 46 are installed at the edge of the baffle.

[0057] The foot pedal can be replaced with a manual button according to actual conditions.

[0058] By stepping on the foot pedal, the toilet seat cover and the closing plate are opened and closed synchronously by utilizing the rotational cooperation among the closing plate shaft, the transmission arm, the fixed shaft one, the transmission lever, the movable shaft one, the movable shaft two, the movable shaft three, the fixed bracket, the fixed shaft two and the foot pedal connecting rod. Compared with the original design, this embodiment has lower manufacturing cost and is more convenient to use.

[0059] Embodiment 2:

[0060] When the toilet seat cover is opened, the main sealing plate 49 is automatically opened through the system structure. When position one 51 is opened, position two 52 is closed. At the same time, the secondary sealing plate 50 is connected to the main sealing plate 49 through a spring. The secondary sealing plate 50 is closed at position three 53, and feces fall into the bottom of the special plastic bag 24. After using the toilet, put down the toilet seat cover, drive the main sealing plate 49 to close through the mechanism system, and position two 52 and position three 53 are opened at the same time. Feces naturally fall into the bottom of the container, and the secondary sealing plate 50 is closed at the same time. The difference from the original design is that two secondary sealing plates 50 and springs are added. At this time, there is no space in the special plastic bag 24 below position one 51, and there will be no odor next time it is used. This design is more suitable for bedside toilets. When the container is produced, a kind of oil is sprayed into the inner wall so that feces will not stick.

[0061] Compared with the original design, the sealing plate of this design adopts a structure in which the main sealing plate 49 is connected to the auxiliary sealing plate 50 below through a spring, and the auxiliary sealing plate 50 and the main sealing plate 49 work synchronously. The difference is that when the main sealing plate 49 is opened, the auxiliary sealing plate 50 is synchronously closed from position one 51 to position two 52 and then to position three 53, and the feces naturally falls when the main sealing plate 49 is at position three 53 to position 52; when the main sealing plate 49 is completely closed, it is closed again from position two 52 to position one 51, so that there is no space in the special plastic bag between the main sealing plate 49 and the auxiliary sealing plate 50, and no odor will come out when it is opened next time.
