[0033] Referring to Figure 1 , Figure 2 , Figure 7 and Figure 8According to the first aspect embodiment of the utility model, the delay automatic closing cover plate comprises a fixing base 110, a bottom ring 210, a faceplate 220, a first reset structure 230, a damping limiting device 310 and an air device 320, the bottom ring 210 is rotatably installed on the fixing base 110, the faceplate 220 is rotatably installed on the fixing base 110, the faceplate 220 has an open position and a closed position, when the faceplate 220 rotates to the closed position, the faceplate 220 is closed on the bottom ring 210, the first reset structure 230 is arranged between the faceplate 220 and the fixing base 110, the damping limiting device 310 is arranged between the fixing base 110 and the faceplate 220, the air device 320 is arranged on the fixing base 110, the air device 320 is drivingly connected with the faceplate 220, an air flow channel 310b is arranged between the air device 320 and the damping limiting device 310, the air flow channel 310b is provided with a valve device 400 matched with the bottom ring 210, in the process of rotating the faceplate 220 from the closed position to the open position, the faceplate 220 can drive the air device 320 to exhaust or send air to the damping limiting device 310 through the air flow channel 310b, so as to drive the damping limiting device 310 to limit the faceplate 220 to the open position, wherein when the bottom ring 210 is in a pressure state, the valve device 400 is closed, when the bottom ring 210 is in a non-pressure state, the valve device 400 is opened, the air flow channel 310b is communicated with the outside of the air flow channel 310b through the valve device 400, so as to make the damping limiting device 310 release the limitation on the faceplate 220, when the damping limiting device 310 releases the limitation on the faceplate 220, the first reset structure 230 can drive the faceplate 220 to rotate from the open position to the closed position.

[0034] The delay automatic closing cover plate provided by the utility model, when a user defecates, the user can rotate the panel 220 from the closed position to the open position by hand, in this process, the panel 220 can drive the air device 320 to draw air or send air to the damping limiting device 310 through the airflow channel 310b, so as to drive the damping limiting device 310 to limit the panel 220 to the open position through the damping force, when the panel 220 is in the open position, if a person sits on the bottom ring 210, the bottom ring 210 is in a pressure state, at this time, the valve device 400 is closed, so that the airflow channel 310b cannot exchange air with the outside of the airflow channel 310b, and then the damping limiting device 310 keeps the limiting effect on the panel 220, so that the panel 220 can be kept in the open position for a long time, when the user finishes defecating and leaves the bottom ring 210, the bottom ring 210 is in an unpressurized state, at this time, the valve device 400 is opened, the airflow channel 310b can exchange air with the outside of the airflow channel 310b through the valve device 400, and then the damping limiting device 310 releases the limitation on the panel 220, because the airflow channel 310b needs a period of time to complete air exchange, so that the damping limiting device 310 needs a period of time to complete unlocking, therefore, after the user finishes defecating for a period of time, the first reset structure 230 can drive the panel 220 to rotate from the open position to the closed position, thus, the delay automatic closing cover plate provided by the utility model can automatically close the panel 220 after the user finishes defecating for a period of time, solves the pain point that the user forgets to close the panel 220 after defecating, and is more conducive to health.

[0035] The damping limiting device 310 limits the rotation of the panel 220 by applying damping force to the panel 220, as long as the user uses a certain force to overcome the damping force applied by the damping limiting device 310, the user can manually rotate the panel 220 from the open position to the closed position. Therefore, the delay automatic closing cover plate provided by the utility model allows the user to manually close the panel 220 according to needs, retains the use characteristics of a traditional closestool, and avoids the damage of the panel 220 when forcibly pushing the panel 220 from the open position to the closed position.

[0036] In addition, the entire delay automatic closing cover plate can automatically close the panel 220 through mechanical structure, does not need to set electronic structure prone to failure in a humid environment, does not need to configure a power supply, has long service life and high operation reliability.

[0037] In the implementation process, the first reset structure 230 can be set as a torsion spring. Of course, the first reset structure 230 can also be set in other ways, for example, the first reset structure 230 is set as an elastic cable, or the first reset structure 230 includes two magnets, one of which is installed on the panel 220 and the other is installed on the fixed seat 110, and the panel 220 can be driven to rotate by the attractive force or repulsive force generated between the two magnets.

[0038] With reference to Figure 2 , Figure 3 and Figure 5 , according to some embodiments of the utility model, the damping limiting device 310 includes a suction cup 311 and a baffle 312, the suction cup 311 and the baffle 312 are oppositely arranged, the suction cup 311 is installed on the panel 220, the baffle 312 is installed on the fixed seat 110, the suction cup 311 and the baffle 312 enclose a gas cavity 310a, an air flow channel 310b is in communication with the gas cavity 310a, when the panel 220 rotates from the closed position to the open position, the panel 220 can drive the air device 320 to exhaust the gas cavity 310a through the air flow channel 310b, so that a negative pressure is formed in the gas cavity 310a, thereby the suction cup 311 is tightly adsorbed on the baffle 312, and thus the damping force between the suction cup 311 and the baffle 312 is increased, and the panel 220 is prevented from being driven away from the open position by the first reset structure 230. With the above setting, the damping limiting device 310 is simple in structure, low in cost and convenient to install.

[0039] With reference to Figure 2 , Figure 3 and Figure 5 , according to some embodiments of the utility model, the fixed seat 110 is rotatably installed with a rotating shaft 240, a first end of the rotating shaft 240 is connected with the panel 220, a second end of the rotating shaft 240 is oppositely arranged with the baffle 312, the suction cup 311 is installed on the second end of the rotating shaft 240, and the suction cup 311, the rotating shaft 240 and the panel 220 are synchronously rotatably arranged. With the above setting, during the rotation of the panel 220 from the closed position to the open position, the panel 220 can drive the rotating shaft 240 and the suction cup 311 to synchronously rotate coaxially, in this process, the suction cup 311 and the baffle 312 can be tightly attached, avoiding the air leakage of the gas cavity 310a during the air extraction of the gas cavity 310a by the air device 320, so that the damping limiting device 310 works reliably, and in addition, the rotating distance of the suction cup 311 relative to the baffle 312 can be reduced, and the wear of the suction cup 311 can be reduced.

[0040] Wherein, since the suction disc 311 is a component with elasticity, when the air device 320 exhausts the air cavity 310a, the suction disc 311 can be deformed to adhere to the baffle 312, when the valve device 400 is opened, under the elastic force of the suction disc 311, air can enter the airflow channel 310b from outside, the air in the airflow channel 310b can enter the air cavity 310a, and finally the suction disc 311 returns to the original state, so that the damping force between the suction disc 311 and the baffle 312 decreases, and then the first reset structure 230 can drive the panel 220 to rotate from the open position to the closed position, and after the suction disc 311 returns to the original state, the damping limiting device 310 can be used again.

[0041] It should be noted that the damping limiting device 310 described above can also be arranged in other ways, for example, the damping limiting device 310 can include two oppositely arranged clamping jaws and a driving cylinder, the driving cylinder is in communication with the air device 320 through the airflow channel 310b, and the driving cylinder is in transmission connection with the two clamping jaws, so that the air device 320 provides the required power for the driving cylinder by exhausting or supplying air to the driving cylinder, so that the driving cylinder can drive the two clamping jaws to clamp the rotating shaft 240, thereby increasing the damping force received by the rotating shaft 240, and further limiting the panel 220 from leaving the open position. Wherein, the driving cylinder is provided with a spring for resetting the piston, when the valve device 400 is opened, the spring can drive the piston of the driving cylinder to gradually reset, and at the same time, the two clamping jaws are opened, so that the damping limiting device 310 can be used again.

[0042] Referring to Figure 2 , Figure 3 and Figure 5 , according to some embodiments of the present application, the air device 320 includes a first piston 321 and a first cylinder body 322 arranged on the fixed seat 110, the first cylinder body 322 is provided with a first cylinder cavity 3221, the airflow channel 310b is in communication with the first cylinder cavity 3221, the first piston 321 is slidably installed in the first cylinder cavity 3221, the first piston 321 is in transmission connection with the panel 220, and when the panel 220 rotates relative to the fixed seat 110, the panel 220 can drive the first piston 321 to slide. With the above arrangement, the air device 320 is simple in structure, easy to install and low in cost.

[0043] Wherein, the airflow channel 310b is in communication with one end of the first cylinder cavity 3221, when the panel 220 drives the first piston 321 to slide away from the airflow channel 310b, the volume of the first cylinder cavity 3221 in communication with the airflow channel 310b increases, thereby realizing the air exhaust of the airflow channel 310b.

[0044] It should be noted that in some other embodiments, the air device 320 may also adopt other configurations. For example, the air device 320 may include an elastic airbag and a push-pull member. The push-pull member is connected to the panel 220 in a transmission manner. Thus, when the panel 220 rotates from the closed position to the open position, the panel 220 can drive the push-pull member to push and pull the airbag, so that the airbag is deflating or deflated.

[0045] Reference Figure 2 , Figure 4 and Figure 5 According to some embodiments of the present invention, the valve device 400 includes a second piston 410 and a second cylinder 420 disposed on a fixed base 110. The second cylinder 420 has a second cylinder cavity 421 communicating with the airflow channel 310b. An air inlet 422 is provided on the outer surface of the second cylinder 420 and communicates with the second cylinder cavity 421. The second piston 410 is slidably installed in the second cylinder cavity 421. The second piston 410 abuts against the bottom ring 210. A second reset structure 430 is provided between the second piston 410 and the second cylinder 420 or between the second piston 410 and the bottom ring 210. When the bottom ring 210 is under pressure, the bottom ring 210 can drive the second piston 410 to block and close the air inlet 422. When the bottom ring 210 is not under pressure, the second reset structure 430 can drive the second piston 410 to slide away from the air inlet 422. With the above configuration, the valve device 400 has a simple structure, reliable operation, and low cost.

[0046] The larger the air inlet 422, the faster the air exchange is completed by the airflow channel 310b, and the shorter the delay time of the panel 220 closing. The smaller the air inlet 422, the slower the air exchange is completed by the airflow channel 310b, and the longer the delay time of the panel 220 closing. The actual size of the air inlet 422 can be determined by those skilled in the art according to actual needs, and is not limited here.

[0047] Reference Figure 5 In the specific implementation process, the valve device 400 includes a pipe 440, and the airflow channel 310b is connected to the second cylinder chamber 421 through the pipe 440.

[0048] In specific implementation, the second reset structure 430 can be set as a spring, elastic cable or other structure, without limitation.

[0049] It is conceivable that in some other embodiments, the second piston 410 described above can be connected to the bottom ring 210 in a driving connection. When the bottom ring 210 rotates between the compressed state and the uncompressed state, the bottom ring 210 can drive the second piston 410 to slide, thereby opening and closing the air inlet 422. With this configuration, the second reset structure 430 described above does not need to be configured.

[0050] In other embodiments, the valve device 400 can also be arranged in other ways, for example. The valve device 400 can be arranged as a ball valve, and the valve core of the ball valve is in driving connection with the bottom ring 210. When the bottom ring 210 is switched between the pressure state and the unpressurized state, the bottom ring 210 can drive the valve core of the ball valve to rotate to open or close the ball valve.

The arrangement of the rotating shaft 240 can provide more installation space for the damping limiting device 310, the air device 320 and other components, and the installation is more convenient.

[0052] With reference to Figure 2 , Figure 5 and Figure 6 , according to some embodiments of the utility model, the first piston 321 is connected with a shaft sleeve 510, the shaft sleeve 510 is slidably sleeved on the rotating shaft 240, the rotating shaft 240 is fixedly provided with a transmission part 241, the transmission part 241 is in driving cooperation with the shaft sleeve 510, and when the panel 220 is rotated from the closed position to the open position, the rotating shaft 240 drives the transmission part 241 to drive the shaft sleeve 510 to slide, so that the shaft sleeve 510 drives the first piston 321 to slide.

[0053] With reference to Figure 5 and Figure 6 , in some embodiments, the transmission part 241 is located on one side of the shaft sleeve 510, and the transmission part 241 and the shaft sleeve 510 are in driving cooperation through a spiral inclined surface.

[0054] In other embodiments, the transmission part 241 and the shaft sleeve 510 can also be in driving cooperation through threads.

[0055] With reference to Figure 2 , Figure 3 and Figure 5According to some embodiments of the utility model, fixed seat 110 detachably installs pressure block 120, pressure block 120 and fixed seat 110 mutually cooperate and hold first cylinder body 322, pressure block 120 is provided with guide chute 121, guide chute 121 is provided with pull block 520 slidingly, pull block 520 and first piston 321 are connected, shaft sleeve 510 is provided with push part 511, push part 511 is inserted in pull block 520, and third reset structure 530 is arranged between pull block 520 and pressure block 120.

[0057] In the specific implementation process, the third reset structure 530 can be a spring, an elastic cable or other structures, which is not limited here.

[0058] Referring to Figure 2 and Figure 5 According to some embodiments of the utility model, a bumper 600 is arranged between the fixed seat 110 and the panel 220, and the bumper 600 is used to buffer the rotation speed of the panel 220 when rotating to the closed position. Through the bumper 600, the rotation speed of the panel 220 when approaching the closed position can be reduced, preventing the panel 220 from rotating quickly to the closed position and causing strong collision between the panel 220 and the bottom ring 210, protecting the panel 220 and the bottom ring 210, reducing the sound when the panel 220 is closed, and achieving a mute effect.

[0061] Of course, it can be imagined that the above-mentioned delay automatic closing cover plate can also be applied to other occasions where the panel 220 is needed.
