Description

[0001] The invention belongs to the technical field of toilets, and in particular relates to a water tankless toilet with an adjustable water seal amount capable of setting the water seal height of the toilet as required. Background Art

[0002] The tankless toilets currently on the market have eliminated the traditional toilet tank and use natural water direct flushing. The tap water sprayed out has high pressure, good cleaning effect, and low water consumption. This toilet tank flushing method determines that the water seal height of the toilet is different after cleaning, and even fails to meet industry requirements. After cleaning the toilet, the industry requires that the water seal height of the toilet is generally controlled at 50-100mm. The water seal height determines the anti-odor, anti-insect and anti-bacteria effect of the toilet. At present, after the discharge (sewage) valve of the tankless toilet is closed, the flushing tap water flow valve (angle valve) is also closed immediately, and it is difficult to ensure that there is enough water seal after flushing the toilet. Summary of the invention

[0003] The purpose of the present invention is to provide a water tankless toilet with adjustable water seal volume, and to slow down the closing speed of a water pipe flow valve to adjust the water seal volume of the toilet.

[0005] The adjustment mechanism includes a mounting ring and a rotating disk for linkage with the flow valve shaft. The rotating disk is rotatably placed in the mounting ring and is connected to a reset component that can drive the rotating disk to rotate and reset. A friction component for adjusting the reset speed of the rotating disk is provided between the mounting ring and the rotating disk.

[0006] The friction assembly moves radially and is circumferentially limited on the mounting ring.

[0007] The inner ring of the installation ring is radially formed with a limiting groove, and the friction component is assembled in the limiting groove.

[0008] The friction assembly includes an adjusting bolt, a radial motion part and a friction part arranged from outside to inside. The adjusting bolt is threaded on the outside of the mounting ring. The inner end of the adjusting bolt radially penetrates the mounting ring body and the limiting groove and then abuts against the radial motion part, and the friction part abuts against the rotating disk.

[0009] The contact surface between the friction part and the rotating disk is in an arc shape matching the outer contour of the rotating disk.

[0010] The outer diameter of the body at the junction of the rotating disk and the friction part is greater than the outer diameter of the body at other positions of the rotating disk.

[0011] The reset component is a clockwork spring.

[0012] An assembly ring is also provided between the installation ring and the rotating disk. The assembly ring is axially provided with a countersunk hole, and the rotating disk is placed in the countersunk hole. An axial hole is provided at the countersunk hole for the flow valve shaft to pass through. The assembly ring is radially provided with a notch groove for the friction component to pass through radially.

[0013] The friction components are divided into two groups and are symmetrically arranged on the mounting ring.

[0014] The toilet shell is provided with a foot pedal mechanism for controlling the opening and closing of the valve of the sewage discharge mechanism, and a gear is provided on the rotating shaft of the sewage discharge mechanism; the foot pedal mechanism includes a pedal, an extension rod, a pedal rod, a bracket, and a rack. The pedal rod and the bracket are placed in the base of the toilet shell, the bracket is fixed on the base of the toilet shell, the pedal rod is hinged on the bracket, a through groove is provided on the side wall of the shell base, the extension rod passes through the through groove, the outer end of the extension rod extends to the outside of the shell base and is connected to the pedal; a plug-in hole is formed axially at the inner end of the extension rod, a spring sheet is hollowed out on a wall of the extension rod at the plug-in hole, the outer end of the pedal rod is fitted in the plug-in hole, a groove is formed at the contact surface between the outer wall of the pedal rod and the spring sheet, and the free end of the spring sheet rests in the groove; the inner end of the pedal rod is hinged to the lower end of the rack, and the rack is meshed with the gear; the gear and the rotating disk are connected via a connecting rod mechanism, and the rotating disk is linked to the gear via the connecting rod mechanism.

[0015] The technical effects of the present invention are as follows: 1. The present invention is provided with an adjustment mechanism, through which the rotating disk is linked with the rotating shaft of the flow valve. During the resetting process, the rotating disk is acted upon by friction, which prolongs the resetting time of the flow valve and increases the water seal amount. 2. The friction component can realize radial movement, and the friction force can be adjusted as needed, thereby adjusting the closing time of the flow valve and realizing on-demand control of the water seal height. 3. The outer diameter of the main body at the junction of the rotating disk and the friction part is slightly larger, which can achieve the effect of fast flushing and slow water stopping, reduce the resistance to the sewage discharge mechanism, and better control the water seal height.

[0016] Preferably, the friction assembly moves radially and is circumferentially limited on the mounting ring. The radial extrusion friction setting has a better friction effect than the axial extrusion friction setting, and is easier to process and assemble.

[0017] Preferably, a limiting groove is radially formed in the inner ring of the installation ring, and the friction assembly is assembled in the limiting groove, which is convenient for processing.

[0018] Preferably, the friction assembly includes an adjustment bolt, a radial motion part and a friction part arranged from outside to inside, the adjustment bolt is threaded on the outside of the mounting ring, the inner end of the adjustment bolt radially penetrates the mounting ring body and the limit groove and then abuts against the radial motion part, and the friction part abuts against the rotating disk. The friction force can be changed by rotating the adjustment bolt from the outside, which is easy to operate. At the same time, when the friction part is worn, it is also convenient to replace the friction part.

[0019] Preferably, the contact surface between the friction part and the rotating disk is in an arc shape matching the outer contour of the rotating disk. The contact surface is in an arc shape, the area of ​​the friction surface is larger, and the rotation speed of the rotating disk is more uniform during the resetting process.

[0020] As an improvement, the outer diameter of the body at the junction of the rotating disk and the friction part is larger than the outer diameter of the body at other positions of the rotating disk. When the flow valve is opened, that is, when the external force drives the rotating disk or the flow valve shaft, after the part with a larger outer diameter of the rotating disk is separated from the friction part, the friction between the part with a smaller outer diameter of the rotating disk and the friction part becomes smaller, and the resistance generated by the rotating disk becomes smaller. When the external force is removed, under the action of the reset spring, the flow valve begins to close. In the first half of the rotation of the rotating disk, the resistance of the friction part is small and the speed is fast; in the second half of the rotation of the rotating disk, the part with a larger outer diameter of the rotating disk comes into play, and the resistance of the friction part is large, and the reset speed of the rotating disk is slow.

[0021] Preferably, the reset component is a clockwork spring, which can produce torsion in its own plane and has better stability.

[0022] As an improvement, an assembly ring is further provided between the installation ring and the rotating disk, the assembly ring is provided with a countersunk hole axially, the rotating disk is placed in the countersunk hole, an axial hole is provided at the countersunk hole for the flow valve shaft to pass through, and a notch groove is provided radially for the friction assembly to pass through radially.

[0024] As an improvement, the rotating disk is externally connected with a driving rod that rotates synchronously with the rotating disk, so that an external force can be applied to the rotating disk to control the opening of the flow valve.

[0025] As an improvement, a foot pedal mechanism for controlling the opening and closing of the valve of the sewage discharge mechanism is provided in the toilet shell, and a gear is provided on the rotating shaft of the sewage discharge mechanism; the foot pedal mechanism includes a pedal, an extension rod, a pedal rod, a bracket, and a rack. The pedal rod and the bracket are placed in the base of the toilet shell, the bracket is fixed on the base of the toilet shell, the pedal rod is hinged on the bracket, a through groove is provided on the side wall of the shell base, the extension rod passes through the through groove, the outer end of the extension rod extends to the outside of the shell base and is connected to the pedal; a plug-in hole is formed axially at the inner end of the extension rod, a spring sheet is hollowed out on a wall of the extension rod at the plug-in hole, the outer end of the pedal rod is fitted in the plug-in hole, a groove is formed at the contact surface between the outer wall of the pedal rod and the spring sheet, and the free end of the spring sheet rests in the groove; the inner end of the pedal rod is hinged to the lower end of the rack, and the rack is meshed with the gear; the gear and the rotating disk are connected via a connecting rod mechanism, and the rotating disk is linked to the gear via the connecting rod mechanism.

DETAILED DESCRIPTION

[0055] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0056] like Figure 1-Figure 28 As shown in the embodiment, a water-sealing tankless toilet with adjustable water seal comprises a toilet shell 10, an inner tank, and a water pipe flushing mechanism 8. The inner tank is placed in the toilet shell 10, and a sewage discharge mechanism 18 is connected below the sewage discharge port of the inner tank. The water pipe flushing mechanism 8 comprises a flow valve 7. In this embodiment, the flow valve 7 is an angle valve. The flow valve shaft 17 is connected with an adjustment mechanism for controlling the closing speed of the flow valve 7. In this embodiment, the adjustment mechanism comprises a mounting ring 11 and a rotating disk 12 for linkage with the flow valve shaft 17. The rotating disk 12 is rotatably placed in the mounting ring 11 and is connected with a reset component 13 that can drive the rotating disk 12 to rotate and reset; the outer contour of the rotating disk 12 is circular, and a mounting hole is provided in the mounting ring 11, and the rotating disk 12 is installed in the mounting hole; a friction component 14 for adjusting the reset speed of the rotating disk 12 is provided between the mounting ring 11 and the rotating disk 12. In the embodiment, the friction component 14 moves radially and is circumferentially limited on the mounting ring 11. It means that the friction component 14 can move radially, but is circumferentially limited. Specifically, a limiting groove 11.1 is radially formed on the inner ring of the mounting ring 11, and the friction assembly 14 is assembled in the limiting groove 11.1. In this embodiment, the limiting groove 11.1 directly axially penetrates the two end faces of the mounting ring 11, and of course, it can also only penetrate the end face of the mounting ring 11 body on the same side as the outer end face of the rotating disk 12. Fig.10 shown.

[0057] In this embodiment, combined with Fig.11 , Fig.12As shown, the friction assembly 14 includes an adjusting bolt 14.1, a radial motion part 14.2 and a friction part 14.3 arranged from the outside to the inside. The adjusting bolt 14.1 is screwed on the outside of the mounting ring 11. The inner end of the adjusting bolt 14.1 radially penetrates the mounting ring 11 body and the limiting groove 11.1 and then abuts against the radial motion part 14.2. The radial motion part 14.2 abuts against the adjusting bolt 14.1 and is provided with a pit; the friction part 14.3 abuts against the rotating disk 12. In the embodiment, the radial motion part 14.2 and the friction part 14.3 are separately formed. Of course, the radial motion part 14.2 and the friction part 14.3 can also be integrally formed. The purpose of the separate forming in this embodiment is to facilitate the replacement of the friction part 14.3. The friction part 14.3 is made of rubber or silicone or other similar materials. In this embodiment, the friction part 14.3 is made of silicone.

[0058] In this embodiment, in order to improve the resetting stability of the rotating disk 12, the contact surface between the friction part 14.3 and the rotating disk 12 is an arc shape matching the outer contour of the rotating disk 12. At the same time, the friction components 14 are divided into two groups and are symmetrically arranged on the mounting ring 11.

[0059] In this embodiment, the outer diameter of the body at the junction of the rotating disk 12 and the friction part 14.3 is larger than the outer diameter of the body at other positions of the rotating disk 12. When the flow valve is opened, that is, when the external force drives the rotating disk 12 or the rotating shaft of the flow valve, after the part with a large outer diameter of the rotating disk 12 is separated from the friction part 14.3, the friction between the part with a small outer diameter of the rotating disk 12 and the friction part 14.3 becomes smaller, and the resistance generated by the rotating disk 12 becomes smaller. When the external force is cancelled, under the action of the reset spring, the flow valve begins to reset and close. The first half of the rotation of the rotating disk 12 is subject to less resistance from the friction part 14.3 and the speed is faster; in the second half of the rotation of the rotating disk 12, the part with a large outer diameter of the rotating disk 12 comes into play, and is subject to greater resistance from the friction part 14.3, and the reset speed of the rotating disk 12 is slow. After the present invention is applied to a toilet, the effect of fast flushing and slow water stop can be achieved.

[0060] In the embodiment, the reset component 13 is a spring, one end of which is connected to the rotating shaft of the rotating disk 12 (also the rotating shaft of the flow valve), and the other end is connected to the inner wall of the assembly ring 15. The rotating disk 12 is located outside the reset component 13; in another embodiment, it can also be connected to the inner wall of the mounting ring 11. When the spring is connected to the inner wall of the assembly ring 15, the spring is located inside the assembly ring 15. The reset component 13 can also be a torsion spring, or other springs that can generate a reset force.

[0061] In another embodiment, an assembly ring 15 is further provided between the mounting ring 11 and the rotating disk 12. The assembly ring 15 is axially provided with a countersunk hole 15.1. The rotating disk 12 is placed in the countersunk hole 15.1. An axial hole 15.2 is provided at the countersunk hole 15.1 for the flow valve shaft to pass through. The assembly ring 15 is radially provided with a notch groove 15.3 for the friction assembly 14 to pass through radially.

[0062] In another embodiment, the toilet housing 10 is provided with a foot pedal mechanism for controlling the opening and closing of the valve of the sewage discharge mechanism 18, and a gear 18.1 is provided on the rotating shaft of the sewage discharge mechanism 18; the foot pedal mechanism includes a pedal 2, a pedal rod 3, a bracket 4, an extension rod 5, and a rack 19, the pedal rod 3 and the bracket 4 are placed in the housing base 1 of the toilet housing 10, the bracket 4 is fixed on the housing base 1, the pedal rod 3 is hinged on the bracket 4, a through groove 1.1 is provided on the side wall of the housing base 1, the extension rod 5 penetrates the through groove 1.1, and the outer end of the extension rod 5 extends outside the housing base 1 and is connected to the pedal 2 The inner end of the extension rod 5 is axially formed with an insertion hole 5.1, and a spring piece 5.2 is hollowed out on one wall of the extension rod 5 at the insertion hole 5.1. The outer end of the pedal rod 3 is fitted in the insertion hole 5.1, and a groove 3.1 is formed at the contact surface between the outer wall of the pedal rod 3 and the spring piece 5.2, and the free end of the spring piece 5.2 is against the groove 3.1; the inner end of the pedal rod 3 is hinged to the lower end of the rack 19, and the rack 19 is meshed with the gear 18.1; the gear 18.1 is connected to the rotating disk 12 via a connecting rod mechanism 16, and the rotating disk 12 is linked to the gear 18.1 via the connecting rod mechanism 16.

[0063] In another embodiment, the housing base 1 forms a water collection area 1.2 around the inner side of the through groove 1.1, and the housing base 1 is provided with a drain port 1.3 at the bottom of the water collection area 1.2. A latch 3.2 is provided at the inner end of the pedal rod 3, and a roller 3.3 is sleeved on the latch 3.2. The inner end of the pedal rod 3 is generally connected to the control member of the drain valve, and the provision of the roller 3.3 reduces the wear between the inner end of the pedal rod 3 and the control member, and also reduces the noise. Fig.28 As shown, the pedal 3 includes two parallel rods 3.4 and a crossbar 3.5 for connecting the two parallel rods 3.4. The two parallel rods 3.4 are both equipped with a bracket 4 and are hinged to the bracket 4. Generally, the drain valve of bathroom equipment is relatively far back. Two parallel rods are used to transmit force. The pedal can be designed to be closer to the front side of the bathroom equipment to facilitate users to step on it. Fig.19 As shown, the control part of the drain valve (the rack 19) and the extension rod 5 are not on the same axis. In order to make the pedal 2 closer to the front side of the bathroom equipment after being installed on the extension rod 5, the pedal rod 3 is designed into this mechanism.

[0064] In another embodiment, the connecting rod mechanism 16 includes a connecting rod 16.1, a first rotating rod 16.2, and a second rotating rod 16.3. The first rotating rod 16.2 is linked to the rotating disk 12, and the second rotating rod 16.3 is linked to the gear 18.1. One end of the connecting rod 16.1 is hinged to the free end of the second rotating rod 16.3, and the other end of the connecting rod 16.1 is provided with a slide groove 16.4. The free end of the first rotating rod 16.2 is movably matched in the slide groove 16.4. The two realize one-way limit, which means that when the flow valve 7 is opened, the connecting rod 16.1 can push the first rotating rod 16.2 to rotate; after the flushing is completed, when resetting, the connecting rod 16.1 will not rotate with the first rotating rod 16.2.

[0065] The working principle of the present invention is that the pedal 2 is stepped on to drive the rack 19 to move upward, and the rack 19 drives the gear 18.1 to rotate and open the sewage discharge mechanism; while the gear 18.1 rotates, the connecting rod 16.1 on the connecting rod mechanism 16 drives the rotating disk 12 to rotate, and the rotating disk 12 is connected to the rotating shaft 17 of the flow valve 7, driving the rotating shaft 17 to rotate, opening the flow valve 7, and realizing flushing. When the flushing is completed, the pedal 2 is released, the sewage discharge mechanism is closed, and the connecting rod 16.1 of the connecting rod mechanism 16 is reset. At this time, the first rotating rod 16.2 connected to the rotating disk 12 is not reset together with the connecting rod 16.1, but is reset after the connecting rod 16.1. At this time, the reset component 13 (spring spring) is reset, driving the rotating shaft 17 of the flow valve 7 to rotate, and the rotating disk 12 rotates with it. Under the action of the friction component 14, the closing time of the flow valve 7 is slowed down, and the water pipe flushing mechanism 8 continues to discharge water, while the sewage discharge mechanism 18 is already closed at this time, thereby increasing the water seal amount. In addition, the friction force of the friction component 14 can be adjusted as needed to adjust the water output and achieve the purpose of adjusting the water seal height.

[0066] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
