[0037]

[0038]

[0039] ​​Further, the automatic cover provided by the utility model does not directly limit the rotation of the barrel cover 300 by the pneumatic limiting device 120, and the function of manually opening and closing the barrel cover 300 does not interfere with the function of automatically closing the barrel cover 300, in the case that the pneumatic limiting device 120 limits the first reset structure, the user can still cover or open the barrel cover 300 (or the seat ring 200) at any time according to the need, thereby retaining the use characteristics of the traditional closestool, not affecting the experience of traditional users, and meanwhile avoiding the damage of the automatic cover structure caused by manually forcibly opening and closing the barrel cover 300.

[0040] It should be noted that when the male user urinates, the barrel cover 300 is usually opened without sitting on the seat ring 200, in order to meet the needs of the male user urinating, the automatic cover provided by the utility model can make the time for the pneumatic limiting device 120 to complete the air release through the slow leakage valve 700 long enough, and then make the time required for the pneumatic limiting device 120 to complete the unlocking of the first reset structure long enough, so as to ensure that the male user has enough time to urinate after the barrel cover 300 is opened, and then the barrel cover 300 is automatically closed. In the specific implementation process, the time for the pneumatic limiting device 120 to complete the air release through the slow leakage valve 700 can be configured to be about 2 minutes, which basically meets the needs of most male users urinating.

[0041] Referring to Figure 11 , Figure 4 , Figure 7 and Figure 8 , in some embodiments, the barrel cover 300 is rotatably installed on the base 100 through the rotating shaft 400, the barrel cover 300 rotates synchronously with the rotating shaft 400, the hook 410 is arranged on the rotating shaft 400, the first reset structure includes the reset elastic member 500, the reset elastic member 500 is arranged between the rotating shaft 400 and the base 100, the reset elastic member 500 is provided with the reset part 510, the reset part 510 is located on one side of the hook 410, the reset part 510 is used for abutting and cooperating with the hook 410 to reset the rotating shaft 400, and the pneumatic limiting device 120 can limit the reset part 510 to move to limit the reset of the reset elastic member 500. Thus, when the barrel cover 300 rotates from the closed position to the open position, the hook 410 can push the reset part 510 to move to make the reset elastic member 500 elastically deform, at this time, the pneumatic limiting device 120 can limit the reset part 510 to move to limit the reset of the reset elastic member 500, avoiding the reset elastic member 500 driving the rotating shaft 400 to reset, after the pneumatic limiting device 120 releases the limitation on the reset part 510, the reset elastic member 500 resets, thereby the reset part 510 pushes the hook 410 to drive the rotating shaft 400 to rotate and reset, and then the rotating shaft 400 drives the barrel cover 300 to reset from the open position to the closed position.

[0042] Referring to Figure 11In some embodiments, the reset elastic member 500 includes two torsion spring portions 520 sleeved on the rotating shaft 400, and the reset portion 510 is connected between the two torsion spring portions 520. The torsion spring portion 520 has a supporting leg 530 abutting against the base 100. With the above arrangement, the reset elastic member 500 is convenient to install, has high structural strength, and has long service life.

[0043] It should be noted that the first reset structure can also be arranged in other manners. For example, the first reset structure can include a first magnet and a second magnet that magnetically attract each other. The first magnet is mounted on the rotating shaft 400, and the second magnet is mounted on the base 100. The pneumatic limiting device 120 has a blocking piece that can block the magnetic force between the first magnet and the second magnet. Thus, when the pneumatic limiting device 120 drives the blocking piece to move between the first magnet and the second magnet, the magnetic force between the first magnet and the second magnet is weakened, so that the first magnet and the second magnet cannot drive the cover to reset, thereby achieving the function of limiting the working of the first reset structure.

[0044] Referring to Figure 5 , Figure 6 and Figure 11 In some embodiments, the rotating shaft 400 is provided with a rolling portion 420, which is eccentric with respect to the rotation axis of the rotating shaft 400. The rolling portion 420 is in abutting cooperation with the compressed air device 110. Thus, when the bucket cover 300 rotates from the closed position to the open position, the rolling portion 420 can drive the compressed air device 110 to exhaust. With the above arrangement, the transmission structure between the bucket cover 300 and the compressed air device 110 is simple, which can ensure that the bucket cover 300 rotates more conveniently and flexibly, and reduces the noise during rotation.

[0045] In the specific implementation process, the eccentricity of the rolling portion 420 with respect to the rotation axis of the rotating shaft 400 can be designed to be between 5 mm and 30 mm. Of course, the eccentricity can also be designed to be larger.

[0046] Referring to Figure 5 , Figure 6 and Figure 11In some embodiments, the compressed air device 110 comprises a compression cavity 111, a first piston 112 and a second reset structure 113, the compression cavity 111 is arranged on the base 100, the first piston 112 is slidably arranged in the compression cavity 111, the first piston 112 is in abutting cooperation with the rolling part 420, and the second reset structure 113 is arranged between the first piston 112 and the base 100, and the second reset structure 113 is used to drive the first piston 112 to slide towards the direction of the rotating shaft 400. Thus, when the bucket cover 300 rotates from the closed position to the open position, the bucket cover 300 can drive the compressed air device 110 to discharge the air in the compressed air device 110 to the pneumatic limiting device 120 through the first flow channel 130, so as to drive the pneumatic limiting device 120 to limit the operation of the first reset structure, and after the pneumatic limiting device 120 unlocks the first reset structure, the second reset structure 113 can drive the first piston 112 to slide towards the direction of the rotating shaft 400, so that the compressed air device 110 returns air through the air return structure, so as to automatically lower the cover plate next time.

[0047] Referring to Figures 4 to 6 In some embodiments, the first guide part 114 is arranged in the compression cavity 111, the second flow channel 1141 is arranged in the first guide part 114, and the first piston 112 is slidably sleeved on the first guide part 114. With the above arrangement, the movement of the first piston 112 can be more stable.

[0048] Referring to Figure 5 and Figure 6 The one-way valve 600 is arranged in the second flow channel 1141, and the compression cavity 111 communicates with the first flow channel 130 through the second flow channel 1141. By arranging the one-way valve 600 in the second flow channel 1141, which is located inside the compression cavity 111, the air leakage at the one-way valve 600 can be avoided.

[0049] Referring to Figure 5 , Figure 11 In order to facilitate the installation of the one-way valve 600, the side wall of the compression cavity 111 away from the first guide part 114 is provided with a mounting port 1142, the second flow channel 1141 communicates with the mounting port 1142, the mounting port 1142 is provided with a connector 800, the second flow channel 1141 communicates with the first flow channel 130 through the connector 800, and the connector 800 and the inner wall of the second flow channel 1141 cooperate to clampingly fix the one-way valve 600.

[0050] In some embodiments, the air return structure can comprise an air return valve arranged on the side wall of the compression cavity 111, and when the first piston 112 slides towards the rotating shaft 400, the air return valve is opened, so that the external air can enter the compression cavity 111, and the compressed air device 110 returns air.

[0051] Referring to Figure 5and Figure 6 In some embodiments, the first piston 112 comprises a pushing member 1121 and a sealing plug 1122 sleeved on the pushing member 1121 and slidingly sealed with the inner wall of the compression cavity 111, wherein the air return structure comprises an air return gap 1123 between the sealing plug 1122 and the pushing member 1121, the air return gap 1123 is in communication with the environment outside the compression cavity 111, and the sealing plug 1122 is slidingly movable relative to the pushing member 1121 to open and close the air return gap 1123. When the bucket cover 300 rotates from the closed position to the open position, the pushing member 1121 can drive the sealing plug 1122 to move away from the rotating shaft 400, at this time, the sealing plug 1122 is slidingly moved relative to the pushing member 1121 to a position closing the air return gap 1123, so that the sealing plug 1122 and the pushing member 1121 are sealed, thereby the pushing member 1121 and the sealing plug 1122 can exhaust the exhaust gas in the compression cavity 111; when the second reset structure 113 drives the pushing member 1121 to drive the sealing plug 1122 to move towards the rotating shaft 400, the sealing plug 1122 can be slidingly moved relative to the pushing member 1121 to a position opening the air return gap 1123, thereby the compressed air device 110 can return air through the air return gap 1123. With the above arrangement, the sealing plug 1122 can be replaced while the compressed air device 110 returns air, without the need for additional air return valve, thereby reducing the cost.

[0052] In some embodiments, the inner diameter of the compression cavity 111 can be designed to be between 10mm and 50mm, of course, the inner diameter of the compression cavity 111 can also be designed to be larger.

[0053] It should be noted that the above-mentioned compressed air device 110 can also be arranged in other ways, for example, the compressed air device 110 can comprise an air bag and a compression member, the compression member is slidingly installed on the base 100, the compression member is in transmission cooperation with the rolling part 420, the air bag is in communication with the pneumatic limiting device 120 through the first flow channel 130, and the air return structure comprises a one-way air return valve, thereby when the bucket cover 300 rotates from the closed position to the open position, the compression member can compress the air bag to exhaust air into the pneumatic limiting device 120, and when the bucket cover 300 recovers from the open position to the closed position, the air bag returns air through the one-way air return valve to recover to the original state.

[0054] Referring to Figure 4 , Figure 7 and Figure 8In some embodiments, the pneumatic limiting device 120 comprises a gas storage cavity 121, a second piston 122 and a third reset structure 123. One end of the second piston 122 is slidingly arranged in the gas storage cavity 121, and the other end of the second piston 122 is used to abut and cooperate with the reset part 510 to limit the movement of the reset part 510. The third reset structure 123 is used to drive the second piston 122 to slide away from the rotating shaft 400. Thus, when the compressed air device 110 discharges air into the gas storage cavity 121, the second piston 122 can be driven to slide towards the rotating shaft 400, so that the second piston 122 abuts and cooperates with the reset part 510 to limit the movement of the reset part 510, thereby limiting the operation of the first reset structure, and at the same time, the third reset structure 123 stores energy. When the slow leakage valve 700 is opened, the gas storage cavity 121 slowly leaks, so that the third reset structure 123 can only slowly drive the second piston 122 to slide away from the rotating shaft 400, thereby realizing the delay unlocking of the first limiting structure by the pneumatic limiting device 120. Through the above arrangement, the pneumatic limiting device 120 can adopt a cylinder form, which is simple in structure and reliable in operation.

[0055] With reference to Figure 7 and Figure 8 In some embodiments, a second guide part 124 is arranged in the gas storage cavity 121, and the second piston 122 is slidingly sleeved on the second guide part 124, so that the second piston 122 slides more stably.

[0056] With reference to Figure 7 and Figure 11 In the specific implementation process, three guide columns 1221 are arranged on the end of the second piston 122 close to the rotating shaft 400, and guide insertion holes 1211 are formed in the side wall of the gas storage cavity 121 close to the rotating shaft 400. The three guide columns 1221 are correspondingly arranged in the guide insertion holes 1211. Thus, through the cooperation of the guide columns 1221 and the guide insertion holes 1211, the sliding of the second piston 122 is guided, so that the second piston 122 slides more stably, the wear of the second piston 122 is reduced, and at the same time, the rotation of the second piston 122 is limited.

[0057] In some embodiments, the inner diameter of the gas storage cavity 121 can be designed to be between 10 mm and 50 mm. Of course, the inner diameter of the gas storage cavity 121 can also be designed to be larger.

[0058] It can be imagined that the above-mentioned pneumatic limiting device 120 can also adopt other arrangement modes. For example, the pneumatic limiting device 120 can comprise an air bag, a limiting part is arranged on the air bag, the limiting part is slidingly arranged on the base 100, the limiting part abuts and cooperates with the reset part 510, the air bag is connected with the compressed air device 110 through the first flow channel 130, and the air bag is provided with the above-mentioned slow leakage valve 700.

[0059] With reference to Figure 4 ,Figure 9 、 Figure 10 In some embodiments, the slow leak valve 700 comprises a valve seat 710, an elastic wave 730 and a fourth reset structure 740, the valve seat 710 is installed on the base 100, the valve seat 710 is provided with a gas leakage flow channel 711, the gas leakage flow channel 711 is communicated with the pneumatic limiting device 120, the gas leakage flow channel 711 is provided with a gas leakage hole 712, the gas leakage hole 712 is provided with a sealing element 720, the elastic wave 730 is arranged opposite to the gas leakage hole 712, and the fourth reset structure 740 is arranged between the elastic wave 730 and the valve seat 710, wherein when the seat ring 200 is in the seated state, the seat ring 200 is pressed down, the seat ring 200 can drive the elastic wave 730 to abut against the sealing element 720 to close the gas leakage hole 712, at this time, the elastic wave 730 is tightly matched with the sealing element 720, and the slow leak valve 700 is effectively prevented from leaking; when the seat ring 200 is in the unseated state, the seat ring 200 is not pressed down, the fourth reset structure 740 can drive the elastic wave 730 to move away from the sealing element 720 to open the gas leakage hole 712, at this time, the compressed air in the pneumatic limiting device 120 can slowly leak from the gas leakage hole 712 of the slow leak valve 700. By controlling the opening degree of the gas leakage hole 712, the speed of the slow leak valve 700 can be controlled. It can be easily imagined that when the bucket cover 300 is in the closed position, the seat ring 200 is pressed by the bucket cover 300 under the action of the first reset structure, at this time, the seat ring 200 closes the slow leak valve 700.

[0060] It can be imagined that in other embodiments, the slow leak valve 700 described above can also be arranged in other ways, for example, the slow leak valve 700 can be arranged as a ball valve, wherein the valve core of the ball valve is in transmission connection with the seat ring 200, thereby when the seat ring 200 is in the unseated state and enters the seated state, the seat ring 200 can drive the valve core of the ball valve to rotate, thereby closing the ball valve, and when the seat ring 200 leaves the seated state, the seat ring 200 can drive the valve core of the ball valve to rotate to open the ball valve.

[0061] In the specific implementation process, the second reset structure 113 can be arranged as a compression spring, or the second reset structure 113 can be arranged as two magnets cooperating with each other. The third reset structure 123 and the fourth reset structure 740 can refer to the arrangement mode of the second reset structure 113.

[0062] According to the second aspect embodiment of the utility model, the automatic cover plate is arranged on the seat ring 200, and the slow leak valve 700 is arranged on the seat ring 200. When the seat ring 200 is in the seated state, the slow leak valve 700 is closed, thereby preventing the compressed air in the pneumatic limiting device 120 from leaking; when the seat ring 200 is in the unseated state, the slow leak valve 700 is opened, thereby allowing the compressed air in the pneumatic limiting device 120 to slowly leak. Through the arrangement of the slow leak valve 700, the bucket cover 300 can be automatically closed after the user finishes defecating for a period of time, thereby solving the pain point that the user forgets to cover the bucket cover 300 after defecating, and the user can still cover or open the bucket cover 300 (or the seat ring 200) at any time according to the need, thereby retaining the use characteristics of the traditional closestool and not affecting the experience of the traditional user.

[0063] The technical features of the above-described embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they should be considered to be within the scope of the present specification.

[0064] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above-described embodiments, and various changes can be made within the scope of knowledge of those skilled in the art without departing from the spirit of the present application.
