Description

Technical Field

[0001] This invention relates to the field of sanitary ware technology, and particularly to a delayed automatic closing toilet seat and a toilet. Background Technology

[0002] Currently, toilet seats on the market are usually manually closed by flipping down to prevent water stains, dust, and other dirt from getting on the bottom ring when the toilet is not in use, while also reducing water evaporation and bacteria volatilization into the air. However, people often forget to close the seat after leaving the toilet, which is detrimental to hygiene. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a delayed automatic closing cover that can automatically close the panel after a delay when the user has finished using the toilet, solving the problem of users forgetting to close the panel after using the toilet, and is more hygienic.

[0004] The present invention also proposes a toilet with the above-mentioned delayed automatic closing cover.

[0005] According to a first aspect of the present invention, a time-delayed automatic closing cover includes a fixed base, a bottom ring, a panel, a first reset structure, a damping limiting device, and an air device. The bottom ring is rotatably mounted on the fixed base; the panel is rotatably mounted on the fixed base, and the panel has an open position and a closed position. When the panel is rotated to the closed position, the panel closes on the bottom ring; the first reset structure is disposed between the panel and the fixed base; the damping limiting device is disposed between the fixed base and the panel; the air device is disposed on the fixed base, and the air device is drively connected to the panel. An airflow channel is provided between the air device and the damping limiting device, and the airflow channel is configured to... The valve device is configured to engage with the bottom ring. During the rotation of the panel from the closed position to the open position, the panel can drive the air device to draw or supply air to the damping limiting device through the airflow channel, thereby causing the damping limiting device to restrict the panel to the open position. When the bottom ring is under pressure, the valve device is closed; when the bottom ring is not under pressure, the valve device is open. The airflow channel is connected to the outside of the airflow channel through the valve device, allowing the damping limiting device to release the restriction on the panel. When the damping limiting device releases the restriction on the panel, the first reset structure can drive the panel to rotate from the open position to the closed position.

[0006] The delayed automatic closing cover according to embodiments of the present invention has at least the following beneficial effects: When a user uses the toilet, the delayed automatic closing cover allows the user to manually rotate the panel from the closed position to the open position. During this process, the panel can drive an air device to draw or supply air to the damping limiting device through the airflow channel, thereby driving the damping limiting device to restrict the panel to the open position. When the panel is in the open position, if someone is sitting on the bottom ring, the bottom ring is under pressure. At this time, the valve device closes, preventing air exchange between the airflow channel and the outside of the airflow channel. Therefore, the damping limiting device maintains its restrictive effect on the panel, allowing the panel to remain in the open position for an extended period. When the user leaves the bottom ring after using the toilet, the bottom ring is in an unpressurized state. At this time, the valve device opens, and the airflow channel can exchange air with the outside of the airflow channel through the valve device. This causes the damping limit device to release the restriction on the panel. Since it takes some time for the airflow channel to complete the air exchange, the damping limit device also needs some time to unlock. Therefore, after the user has finished using the toilet for a period of time, the first reset structure can drive the panel to rotate from the open position to the closed position. Thus, the delayed automatic closing cover provided by this invention can automatically close the panel after the user has finished using the toilet for a period of time, solving the problem of users forgetting to close the panel after using the toilet, which is more conducive to hygiene.

[0007] According to some embodiments of the present invention, the damping limiting device includes a suction cup and a baffle disposed opposite to each other. The suction cup is mounted on the panel, and the baffle is mounted on the fixed base. The suction cup and the baffle form an air cavity. The airflow channel communicates with the air cavity. When the panel rotates from the closed position to the open position, the panel can drive the air device to draw air from the air cavity through the airflow channel, so that the suction cup is adsorbed onto the baffle.

[0008] According to some embodiments of the present invention, the fixed base is rotatably mounted with a rotating shaft, the first end of the rotating shaft is connected to the panel, the second end of the rotating shaft is disposed opposite to the baffle, the suction cup is mounted on the second end of the rotating shaft, and the suction cup, the rotating shaft and the panel are arranged to rotate synchronously.

[0009] According to some embodiments of the present invention, the air device includes a first piston and a first cylinder disposed on the fixed base. The first cylinder has a first cylinder chamber, and the airflow passage communicates with the first cylinder chamber. The first piston is slidably mounted in the first cylinder chamber and is kinetically connected to the panel. When the panel rotates relative to the fixed base, the panel can drive the first piston to slide.

[0010] According to some embodiments of the present invention, the valve device includes a second piston and a second cylinder body disposed on the fixed base. The second cylinder body is provided with a second cylinder cavity communicating with the airflow channel. An air inlet is provided on the outer surface of the second cylinder body, and the air inlet communicates with the second cylinder cavity. The second piston is slidably mounted in the second cylinder cavity. The second piston abuts against the bottom ring, and a second reset structure is provided between the second piston and the second cylinder body or between the second piston and the bottom ring. When the bottom ring is in a compressed state, the bottom ring can drive the second piston to block and close the air inlet. When the bottom ring is in an uncompressed state, the second reset structure can drive the second piston to slide away from the air inlet.

[0011] According to some embodiments of the present invention, the fixed base is rotatably mounted with a rotating shaft, the first end of the rotating shaft is connected to the panel, the rotating shaft is synchronously rotated with the panel, the rotating shaft is drively connected to the air device, the first reset structure is disposed between the rotating shaft and the fixed base, and the damping limiting device is disposed between the rotating shaft and the fixed base.

[0012] According to some embodiments of the present invention, the first piston is connected to a bushing, the bushing is slidably sleeved on the rotating shaft, and a transmission part is fixedly provided on the rotating shaft. The transmission part is in transmission cooperation with the bushing. When the panel rotates from the closed position to the open position, the rotating shaft drives the transmission part to drive the bushing to slide, so that the bushing drives the first piston to slide.

[0013] According to some embodiments of the present invention, the fixed seat is detachably mounted with a pressure block, the pressure block and the fixed seat cooperate to clamp and fix the first cylinder body, the pressure block is provided with a guide groove, a pull block is slidably disposed in the guide groove, the pull block is engaged with the first piston, the bushing is provided with a pushing part, the pushing part is inserted into the pull block, and a third reset structure is provided between the pull block and the pressure block.

[0014] According to some embodiments of the present invention, a buffer is provided between the fixed base and the panel, the buffer being used to buffer the rotational speed of the panel when it rotates toward the closed position.

[0015] A toilet according to a second aspect of the present invention includes the aforementioned delayed automatic closing lid.

[0016] The toilet according to the embodiments of the present invention has at least the following beneficial effects: by adopting the above-mentioned delayed automatic closing cover, the panel can be automatically closed after a delay after the user finishes using the toilet, solving the problem of the user forgetting to close the panel after using the toilet, which is more conducive to hygiene.

[0032] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0033] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8According to a first aspect embodiment of the present invention, a time-delayed automatic closing cover includes a fixed base 110, a bottom ring 210, a panel 220, a first reset structure 230, a damping limiting device 310, and an air device 320. The bottom ring 210 is rotatably mounted on the fixed base 110; the panel 220 is rotatably mounted on the fixed base 110, and the panel 220 has an open position and a closed position. When the panel 220 is rotated to the closed position, the panel 220 closes on the bottom ring 210; the first reset structure 230 is disposed between the panel 220 and the fixed base 110; the damping limiting device 310 is disposed between the fixed base 110 and the panel 220; the air device 320 is disposed on the fixed base 110, and the air device 320 is drively connected to the panel 220. An airflow channel 310b is provided between the air device 320 and the damping limiting device 310. The airflow channel 310b is equipped with a valve device 400 that cooperates with the bottom ring 210. During the rotation of the panel 220 from the closed position to the open position, the panel 220 can drive the air device 320 to draw or deliver air to the damping limiting device 310 through the airflow channel 310b, so as to drive the damping limiting device 310 to restrict the panel 220 to the open position. When the bottom ring 210 is in a compressed state, the valve device 400 is closed, and when the bottom ring 210 is in an uncompressed state, the valve device 400 is open. The airflow channel 310b is connected to the outside of the airflow channel 310b through the valve device 400, so that the damping limiting device 310 releases the restriction on the panel 220. When the damping limiting device 310 releases the restriction on the panel 220, the first reset structure 230 can drive the panel 220 to rotate from the open position to the closed position.

[0034] The delayed automatic closing cover provided by this invention allows the user to manually rotate the panel 220 from the closed position to the open position when using the toilet. During this process, the panel 220 can drive the air device 320 to draw or supply air to the damping limiting device 310 through the airflow channel 310b, thereby driving the damping limiting device 310 to restrict the panel 220 to the open position through damping force. When the panel 220 is in the open position, if someone is sitting on the bottom ring 210, the bottom ring 210 is under pressure. At this time, the valve device 400 is closed, preventing air exchange between the airflow channel 310b and the outside of the airflow channel 310b. Thus, the damping limiting device 310 maintains its limiting effect on the panel 220, allowing the panel 220 to remain in the open position for a long time. When the user finishes using the toilet and leaves... When the bottom ring 210 is in an unpressurized state, the valve device 400 is open, and the airflow channel 310b can exchange air with the outside of the airflow channel 310b through the valve device 400. This allows the damping limit device 310 to release the restriction on the panel 220. Since it takes time for the airflow channel 310b to complete the air exchange, the damping limit device 310 needs time to unlock. Therefore, after the user has finished using the toilet 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 delayed automatic closing cover provided by the present invention can automatically close the panel 220 after the user has finished using the toilet for a period of time, solving the problem of the user forgetting to close the panel 220 after using the toilet, which is more conducive to hygiene.

[0035] The damping limiting device 310 restricts the rotation of the panel 220 by applying a damping force to it. As long as the user applies sufficient 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 delayed automatic closing lid provided by this invention allows the user to manually close the panel 220 as needed, retaining the characteristics of traditional toilets and avoiding damage to the panel 220 when it is forcibly pushed from the open position to the closed position.

[0036] In addition, the entire delayed automatic closing cover can achieve automatic closing of panel 220 entirely through mechanical structure, without the need for electronic structures that are prone to failure in humid environments, without the need for power supply, with long service life and high operational reliability.

[0037] In specific implementation, 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 can be 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 base 110. The panel 220 can be driven to rotate by the attraction or repulsion generated between the two magnets.

[0038] Reference Figure 2 , Figure 3 and Figure 5 According to some embodiments of the present invention, the damping limiting device 310 includes a suction cup 311 and a baffle 312. The suction cup 311 and the baffle 312 are arranged opposite to each other. The suction cup 311 is mounted on the panel 220, and the baffle 312 is mounted on the fixed base 110. The suction cup 311 and the baffle 312 enclose an air cavity 310a. An airflow channel 310b communicates with the air 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 draw air from the air cavity 310a through the airflow channel 310b, thereby creating a negative pressure in the air cavity 310a. This causes the suction cup 311 to be tightly adhered to the baffle 312, thereby increasing the damping force between the suction cup 311 and the baffle 312, and preventing the panel 220 from being driven away from the open position by the first reset structure 230. With the above configuration, the damping limiting device 310 has a simple structure, low cost, and is easy to install.

[0039] Reference Figure 2 , Figure 3 and Figure 5 According to some embodiments of the present invention, a rotating shaft 240 is rotatably mounted on a fixed base 110. The first end of the rotating shaft 240 is connected to a panel 220, and the second end of the rotating shaft 240 is opposite to a baffle 312. A suction cup 311 is mounted on the second end of the rotating shaft 240. The suction cup 311, the rotating shaft 240, and the panel 220 are arranged to rotate synchronously. With the above arrangement, 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 rotate synchronously and coaxially. During this process, the suction cup 311 and the baffle 312 can fit tightly together, preventing air leakage in the air chamber 310a during the air extraction process of the air device 320, making the damping limiting device 310 work reliably. In addition, it can also reduce the rotation distance of the suction cup 311 relative to the baffle 312 and reduce the wear of the suction cup 311.

[0040] Since the suction cup 311 is an elastic component, when the air device 320 evacuates the air chamber 310a, the suction cup 311 can deform to adhere to the baffle 312. When the valve device 400 is opened, under the elastic force of the suction cup 311, air can enter the airflow channel 310b from the outside of the airflow channel 310b, and the air in the airflow channel 310b can enter the air chamber 310a. Finally, the suction cup 311 returns to its original shape, which reduces the damping force between the suction cup 311 and the baffle 312. As a result, the first reset structure 230 can drive the panel 220 to rotate from the open position to the closed position. After the suction cup 311 returns to its original shape, the damping limit device 310 can be used again.

[0041] It should be noted that the aforementioned damping limiting device 310 can also be configured in other ways. For example, the damping limiting device 310 may include two opposing grippers and a drive cylinder. The drive cylinder is connected to the air device 320 through the airflow channel 310b, and is driven by the two grippers. Thus, the air device 320 provides the necessary power to the drive cylinder by drawing or supplying air, enabling the drive cylinder to drive the two grippers to clamp the rotating shaft 240, thereby increasing the damping force on the rotating shaft 240 and limiting the panel 220 from leaving the open position. The drive cylinder contains a spring for resetting the piston. When the valve device 400 is opened, this spring can drive the piston of the drive cylinder to gradually reset, simultaneously opening the two grippers, thus allowing the damping limiting device 310 to be reused.

[0042] Reference Figure 2 , Figure 3 and Figure 5 According to some embodiments of the present invention, the air device 320 includes a first piston 321 and a first cylinder 322 disposed on a fixed base 110. A first cylinder cavity 3221 is disposed within the first cylinder 3222, and an airflow passage 310b communicates with the first cylinder cavity 3221. The first piston 321 is slidably mounted in the first cylinder cavity 3221. The first piston 321 is kinetically connected to a panel 220. When the panel 220 rotates relative to the fixed base 110, the panel 220 can drive the first piston 321 to slide. With the above configuration, the air device 320 has a simple structure, is easy to install, and has low cost.

[0043] The airflow channel 310b is connected to one end of the first cylinder chamber 3221. When the panel 220 drives the first piston 321 to slide away from the airflow channel 310b, the volume of the first cylinder chamber 3221 connected to the airflow channel 310b increases, thereby achieving air extraction from 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 5According 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 chamber 421 communicating with the airflow channel 310b. An air inlet 422 is formed on the outer surface of the second cylinder 420, communicating with the second cylinder chamber 421. The second piston 410 is slidably mounted in the second cylinder chamber 421. The second piston 410 abuts against a 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, it 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 may also be configured in other ways. For example, the valve device 400 may be configured as a ball valve, with the valve core of the ball valve being drivenly connected to the bottom ring 210. When the bottom ring 210 rotates between a pressurized state and an unpressurized state, the bottom ring 210 can drive the valve core of the ball valve to rotate, thereby opening or closing the ball valve.

[0051] Reference Figure 2 and Figure 5According to some embodiments of the present invention, a rotating shaft 240 is rotatably mounted on the fixed base 110. The first end of the rotating shaft 240 is connected to the panel 220. The rotating shaft 240 and the panel 220 are rotated synchronously. The rotating shaft 240 is connected to the air device 320 for transmission. A first reset structure 230 is disposed between the rotating shaft 240 and the fixed base 110. A damping limiting device 310 is disposed between the rotating shaft 240 and the fixed base 110. The rotating shaft 240 provides more installation space for components such as the damping limiting device 310 and the air device 320, making installation more convenient.

[0052] Reference Figure 2 , Figure 5 and Figure 6 According to some embodiments of the present invention, the first piston 321 is connected to a bushing 510, the bushing 510 is slidably sleeved on the rotating shaft 240, and a transmission part 241 is fixedly provided on the rotating shaft 240. The transmission part 241 and the bushing 510 are in transmission cooperation. 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 bushing 510 to slide, so that the bushing 510 drives the first piston 321 to slide.

[0053] Reference Figure 5 and Figure 6 In some embodiments, the transmission part 241 is located on one side of the bushing 510, and the transmission part 241 and the bushing 510 are connected by a helical inclined surface transmission.

[0054] In other embodiments, the transmission part 241 and the bushing 510 may also be driven by threads.

[0055] Reference Figure 2 , Figure 3 and Figure 5 According to some embodiments of the present invention, a pressure block 120 is detachably mounted on a fixed base 110. The pressure block 120 and the fixed base 110 cooperate to clamp and fix the first cylinder 322. The pressure block 120 is provided with a guide groove 121, and a pull block 520 is slidably disposed in the guide groove 121. The pull block 520 is engaged with the first piston 321. A bushing 510 is provided with a pushing part 511, which is inserted into the pull block 520. A third reset structure 530 is provided between the pull block 520 and the pressure block 120. With the above configuration, the installation of the air device 320 can be facilitated, as can the transmission connection between the air device 320 and the rotating shaft 240, thereby improving the assembly efficiency of the entire delayed automatic closing cover.

[0056] It should be noted that the shaft 240 and the first piston 321 can also be connected by other means of transmission. For example, a gear is installed on the shaft 240 and a rack is provided on the first piston 321, and the rack and gear mesh to transmit power.

[0057] In practice, the third reset structure 530 can be configured as a spring, elastic cable or other structure, without limitation.

[0058] Reference Figure 2 and Figure 5 According to some embodiments of the present invention, a buffer 600 is provided between the fixing base 110 and the panel 220. The buffer 600 is used to buffer the rotational speed of the panel 220 when it rotates to the closed position. The buffer 600 can reduce the rotational speed of the panel 220 when it approaches the closed position, prevent the panel 220 from rotating rapidly to the closed position and causing a strong collision between the panel 220 and the bottom ring 210, protect the panel 220 and the bottom ring 210, reduce the sound when the panel 220 is closed, and achieve a silent effect.

[0059] Reference Figure 7 and Figure 8 According to a second aspect of the present invention, a toilet includes the aforementioned delayed automatic closing lid. By employing the aforementioned delayed automatic closing lid, the panel 220 can automatically close after a delay following the user's use of the toilet, solving the problem of the user forgetting to close the panel 220 after using the toilet, and is more hygienic.

[0060] Reference Figure 7 In some embodiments, the toilet typically also includes a bowl 700, a mounting base 110 fixedly installed on the bowl 700, and when the panel 220 is in the closed position, the panel 220 and the bottom ring 210 are closed together on the bowl 700, thereby closing the opening of the bowl 700.

[0061] Of course, it is conceivable that the aforementioned delayed automatic closing cover can also be applied to other occasions that require panel 220.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
