Description

Technical Field

[0001] This invention relates to the field of sanitary ware technology, specifically to a double-flip-type water-saving device for sanitary ware. Background Technology

[0002] Sanitary ware refers to toilets, squat toilets, seated toilets, and other toiletries. They are essential necessities in daily life. Traditional toilets and squat toilets rely on water momentum for flushing and use S-shaped bends in the drain pipes for water seal and odor prevention. Therefore, they consume a lot of water and are quite noisy. Although various water-saving toilets and squat toilets are available on the market, their water-saving effects are limited. Sanitary ware water consumption still accounts for a large share of household water usage. Furthermore, traditional sanitary ware uses S-shaped bends for draining, which are easily clogged by hard-to-dissolve debris, waste paper, and tissues. This can lead to frequent blockages requiring drain cleaning tools, or even complete replacement of the pipes, causing considerable inconvenience. Summary of the Invention

[0003] To address the aforementioned shortcomings of sanitary ware, this invention provides a double-layer flip-type water-saving device for sanitary ware. Utilizing the weight of excrement and applying mechanical principles, it employs a double-layer flip-type mechanism that flips, rotates, and automatically resets, allowing waste to fall off naturally and be rinsed with a small amount of water for thorough cleaning. Significantly different from traditional S-shaped bend pipe drainage systems, this device achieves highly efficient cleaning, water conservation, and environmental protection. It also features a water seal layer for odor prevention and noise reduction. Furthermore, it avoids the problems of easy clogging and difficult maintenance associated with traditional bend pipes, making it widely applicable to various types of sanitary ware for excrement disposal. The widespread application of this product can save users living expenses. It also saves the country investment and operating costs in water supply and sewage treatment, making it a beneficial and environmentally friendly product that saves energy and water.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: A double-layer flip-type water-saving device for sanitary ware only requires modification to the bottom bend of the toilet and squat toilet. Other components such as the seat, water supply system, and intelligent operating system remain unchanged; only the flushing mechanism operation and water consumption reduction need to be modified. Furthermore, either rotary or direct-pressure operation can be selected according to needs.

[0005] Specific operations: A water-saving cylinder is installed at the bottom of the toilet or squat toilet. The water-saving cylinder consists of an upper cylinder and a lower cylinder. The upper cylinder has an upper drain hole and contains an upper flap and an upper flap shaft. Supports for the upper flap shaft are located at both ends of the upper cylinder. The upper flap shaft passes through the upper flap and is fixed inside, then hinged to the upper flap shaft support. One end of the flap shaft passes through a linkage mechanism, is fitted with gear A, and then a micro-motor is installed, with a knob installed at the end. The lower cylinder also has a lower drain hole and contains a lower flap and a lower flap shaft. Supports for the lower flap shaft are located at both ends of the lower cylinder. The lower flap shaft passes through the lower flap and is fixed inside, then hinged to the lower flap shaft support. One end is inserted into the linkage mechanism and connected to gear B. The linkage mechanism contains a rack. The rack has a rack protrusion with a lower round head in the middle. A return spring is installed between the round head of the rack protrusion and a round protrusion at the bottom of the linkage mechanism. After the water-saving cylinder is installed... (1) When the rotary manual operation mode is selected: Rotate the knob on the end of the upper flap shaft clockwise. The upper and lower flaps can open the upper and lower drain holes simultaneously to discharge dirt. Then, release the knob, and the upper and lower flaps will automatically close and seal the upper and lower drain holes under the action of the return spring and strong magnet. (2) When the direct pressure manual operation mode is selected: Press the direct pressure rod plate to make the rack move up and down, driving gear A and gear B, so that the upper and lower flaps open the upper and lower drain holes simultaneously to discharge dirt. Then, release the direct pressure plate, and the upper and lower flaps will automatically close the upper and lower drain holes simultaneously under the action of the return spring and strong magnet.

[0006] The manual operation using the rotary method is as follows: First, the upper and lower flaps tightly seal the upper and lower drain holes. Open the water supply valve to inject water into the upper cylinder as a water cushion layer, and then guide water through the overflow pipe to the lower cylinder as a water seal layer. After use, the upper cylinder holds the excrement and water cushion water. Rotating the knob clockwise opens the upper and lower drain holes to discharge waste. Releasing the knob automatically resets the upper and lower flaps, sealing the upper and lower drain holes. Then, water cushion water and water seal water are automatically injected for later use. The manual operation using the direct pressure method is as follows: First, complete the rotary operation. After use, press the direct pressure lever to simultaneously open the upper and lower flaps to discharge waste. Then, release the direct pressure lever; the return spring and strong magnet cause the upper and lower flaps to close simultaneously, sealing and releasing water for later use.

[0007] Advantages of the invention: (1) This invention adopts mechanical principle and uses the gravity of the object to discharge and clean, which greatly reduces the amount of water used for flushing and cleaning, and achieves efficient water saving and environmental protection effect.

[0008] (2) The present invention adopts a double-layer flap form to form a water cushion layer and a water seal layer, which solves the problem of odor prevention and reduces noise at the same time.

[0009] (3) The present invention adopts a large channel straight-out structure, which avoids the problem of S-shaped bends being easy to block and difficult to clean.

[0010] (4) This invention only improves the replacement of the S-shaped bend in the original sanitary ware. Other parts, such as the seat, flushing device, and intelligent control system, are only modified to change the operation of the flipping action and the water volume adjustment. The changes are minor and easy for manufacturers to modify and promote. Moreover, due to the low water consumption, the water tank space can be reduced or the water tank can be eliminated, and water can be supplied directly to the municipal water supply pipe. The flushing valve can be omitted, reducing the cost. Attached Figure Description

Detailed Implementation

[0014] Example 1

[0015] The lower part of the toilet 1 is connected to the water-saving cylinder 3, which consists of an upper cylinder 301 and a lower cylinder 302. It also has an upper drain hole 305 and a lower drain hole 306. The upper cylinder 301 contains an upper flap 307. One end of the upper flap shaft 309 passes through the upper flap 307 and is fixed, then hinged to the upper flap shaft supports 310 at both ends of the upper cylinder 301. It then passes through the linkage mechanism 4 and gear A401, and is connected to the micro motor 5, with a knob 315 installed at the end. The lower cylinder 302 also contains a lower flap 308 and a lower flap shaft 319. The lower flap shaft 319 passes through the lower flap 308 and is fixed, then hinged to the lower flap shaft supports 312 at both ends of the lower cylinder 302. It then passes through the linkage mechanism 4 and connects to gear B408. After passing through the linkage mechanism 4, it connects to the micro motor, with a knob 315 installed at the end. The linkage mechanism 4 is equipped with a rack 403. The rack 403 has a protrusion 404 with a lower rounded head in the middle. A return spring 405 is installed between the rounded protrusions 406 at the bottom of the linkage mechanism 4. The upper end of the return spring 405 meshes with gear A 407, and the lower end meshes with gear B 408.

[0016] After installation, two methods can be used for operation: (1) Rotary operation: First, water is injected into the upper cylinder 301, and then water is injected into the lower cylinder 302 through the overflow pipe 303. People can then use the toilet for convenience, and after using the toilet, they can rotate the knob 315 clockwise. The upper flap 307 and the lower flap 308 open the upper drain hole 305 and the lower drain hole 306 simultaneously to discharge waste. After the waste is discharged, the return spring 405 acts on the strong magnets at the ends of the upper flap 307 and the lower flap 308 to make the upper flap 307 and the lower flap 308 reset simultaneously to seal the upper drain hole 305 and the lower drain hole 306. Then water is injected for later use.

[0017] The upper flip-up shaft 309 of the linkage mechanism 4 is connected to a manual knob 315 for driving and a micro motor 5. Both can be driven electrically or manually to drive the upper flip-up shaft 309 and then link it to the lower flip-up shaft 311.

[0018] (2) The direct pressure manual operation is adopted: first, water is poured into the upper cylinder 301, and then water is led to the lower cylinder 302 through the overflow pipe 303. Then people can use the toilet. After using the toilet, press the direct pressure rod plate 415 to open the upper drain hole 305 and the lower drain hole 306 simultaneously to discharge the waste. Then release the direct pressure rod plate 415. Under the attraction of the return spring 405 and the strong magnet 314, the upper drain hole 307 and the lower drain hole 308 simultaneously close the upper drain hole 305 and the lower drain hole 306. Then fill water according to the steps for subsequent use.

[0019] Example 2

[0020] The lower part of the squat toilet 2 is connected to the water-saving cylinder 3, which consists of an upper cylinder 301 and a lower cylinder 302. It also has an upper drain hole 305 and a lower drain hole 306. The upper cylinder 301 contains an upper flap 307. An upper flap shaft 309 passes through the upper flap 307 and is fixed, then hinged to two upper flap shaft supports 310 located at both ends of the upper cylinder 301. It then passes through a linkage mechanism 4 and a gear A407 before being fitted with a micro motor 5, and finally a knob 315 is installed at the end. The lower cylinder 302 also contains a lower flap 308 and a lower flap shaft 319. The lower flap shaft 319 passes through the lower flap 308 and is fixed, then hinged to the lower flap shaft supports 312 located at both ends of the lower cylinder 302. Then, after passing through the linkage mechanism 4 and connecting with gear B408, bevel gear B408 is installed outside the housing of the linkage mechanism 4. Bevel gear B408 meshes perpendicularly with bevel gear A407. Bevel gear A407 is installed at the lower end of transmission rod 409. Knob A410 is installed at the upper end of transmission rod 409. A rack 403 is provided inside the linkage mechanism 4. A protrusion 404 with a lower round head is provided in the middle of the rack 403. A return spring 405 is installed between the round protrusions 406 at the bottom of the linkage mechanism 4 to ensure that the rack 403 moves vertically up and down. The upper end of the rack 403 meshes with gear A407, and the lower end meshes with gear B408.

[0021] After installation, begin filling the upper cylinder 301 with water, which then flows through the overflow pipe 303 into the lower cylinder 302. Rotate the knob 410 clockwise to simultaneously open the upper flap 307 and lower flap 308, allowing waste to drain from the upper drain hole 305 and lower drain hole 306. After draining, the upper flap 307 and lower flap 308 will simultaneously reset and seal the upper drain hole 305 and lower drain hole 306 due to the action of the return spring 405 and the strong magnetic force. Then, fill with water again for future use.
