Description

TECHNICAL FIELD

[0001] The present application relates to a flushing device, particularly applied to a toilet. BACKGROUND

[0002] The toilet generally comprises a toilet seat and a water tank, and a water inlet and outlet valve is installed in the water tank to flush the toilet. In order to ensure sufficient flushing force of the toilet, the water tank is generally made high to utilize the gravitational potential energy of water to flush, and the toilet is large and heavy as a whole, occupying a large bathroom space. Meanwhile, the production of ceramic toilets has a high failure rate and high cost.

[0003] In the bathroom industry, in order to pursue better flushing effect and less flushing, the method of continuously increasing the drain valve diameter is adopted, from the previous common 2-inch drain valve to 3-inch drain valve, and even 3.5-inch to 4-inch drain valve. The adverse consequences of this simple increase in drain valve diameter are that the water tank of the toilet is made larger and larger, and the cost of the drain valve is higher and higher.

[0004] In addition, the mainstream in European countries is a wall-hung toilet with a hidden water tank, and the market requires the hidden water tank to be thinner and thinner, which can reduce the space occupied by the false wall. However, in order to achieve a very thin water tank, the drain valve diameter must be continuously reduced. For example, there are 1.5-inch drain valves on the market, but the flushing force provided by such a small drain valve is not satisfactory, so the thin water tank hidden water tank system cannot be popularized on the market.

[0005] At present, pressure flushing toilets are gradually increasing in the Asia-Pacific and North American markets. There are mainly two kinds. One is to connect a thick hose to the water system through an electromagnetic valve to control the switch to directly flush the toilet. The other is to use a sealed water tank to store the pressure of the water system, and to release the water pressure instantaneously through a flushing valve switch to flush the toilet. This purely water pressure flushing has certain defects. The first kind of water pipe direct flushing needs to use an electromagnetic valve or a water pump and a thick hose, which has an unreliable service life and is greatly affected by surrounding water points, making the flushing unstable. The second kind of pressure flushing water tank is generally large in size, either the water tank is made large or the toilet is made long, and the cost is high, which is not conducive to market promotion and popularization.

DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments of the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0045] Further, the water inlet valve 100 and the hydraulic button 300 are further provided with an anti-siphon vacuum breaker 500, which comprises a vacuum breaker valve cover nut 501 and a vacuum breaker valve core 502. The anti-siphon vacuum breaker 500 is provided to protect the product and prevent the water in the product from flowing back to the water source due to siphon effect when the water supply is interrupted. Specifically, when the water path of the water source is normal, the vacuum breaker valve core 502 does not block the drainage passage. When the water path of the water source is abnormal, due to the pressure difference, the water flow may flow back to the water source, causing safety hazards. At this time, the vacuum breaker valve core 502 can block the drainage passage when the water path of the water source is abnormal, preventing backflow.

[0046] Further, the anti-siphon vacuum breaker 500 is arranged on the water inlet valve 100, and a switching valve mechanism 600 is arranged between the water inlet valve 100 and the anti-siphon vacuum breaker 500.

More specifically, the switching device 320 comprises a switching valve rod 321, which is provided with a valve rod sleeve between the switching valve rod 321 and the key device 330. The switching valve rod 321 is connected with a valve rod spring 322 in a matched manner. The valve rod spring 322 is connected with a gland 323 in a matched manner. The gland 323 is connected with a water stop plug 324 in a matched manner. The water stop plug 324 is connected with a water stop plug spring 325 in a matched manner. The water stop plug spring 325 is connected with a blocking block 326 in a matched manner. The blocking block 326 is connected with a self-cleaning spring 327 in a matched manner. The self-cleaning spring 327 is connected with a water stop seat 328 in a matched manner. The water stop seat 328 is matched with the button body 310. In addition, the key device 330 comprises a key body 331, which is connected with a key cover 332 in a matched manner. The key cover 332 and the key body 331 are provided with a key reset spring 333 therebetween. A nut is arranged between the key reset spring 333 and the key cover 332. A locking nut is arranged between the key body 331 and the valve rod sleeve.

[0049] Further, in the preferred embodiment 1, the drain valve 200 comprises a valve body 201, a valve rod 202 is arranged in the valve body 201, a flushing disc 203 is arranged on the valve rod 202, the valve rod 202 is hollow, a water inlet hole 204 is further arranged on the valve rod 202, a valve cover 205 is connected to the upper end of the valve body 201, a big reset spring 206 is arranged between the valve cover 205 and the valve rod 202, a flap cover 208 is connected to the lower end of the valve rod 202, a rotary switch rod 209 is connected to the flap cover 208, a nozzle pipe 240 is connected to the rotary switch rod 209, and a small reset spring 207 is arranged between the rotary switch rod 209 and the flap cover 208. The above structure realizes that the water flow from the hydraulic button 300 impacts the flushing disc 203, drives the upward movement of the valve rod 202, drives the upward movement of the flap cover 208, opens the water inlet channel of the water tank, and realizes the mixed impact of the water flow of the double water paths.

[0050] Further, in the preferred embodiment 2, the drain valve 200 comprises a valve body 201, a float and a valve rod 202 are arranged in the valve body 201, a flushing disc 203 is arranged on the valve rod 202, the valve rod 202 is hollow, a water inlet hole 204 is further arranged on the valve rod 202, a valve cover 205 is connected to the upper end of the valve body 201, a valve rod reset spring 250 is arranged between the valve cover 205 and the valve rod 202, a nozzle pipe 240 is connected to the lower end of the valve rod 202, a small water stop pad 241 is arranged on the nozzle pipe 240, the small water stop pad 241 can cooperate with the float 260 to seal water, the float 260 is further connected to a float seat 261, a large water stop pad 262 is connected to the float seat 261, and a clamping sleeve 263 is connected to the large water stop pad 262. The above structure realizes that the water flow from the hydraulic button 300 impacts the flushing disc 203, drives the upward movement of the valve rod 202, drives the upward movement of the nozzle pipe 240, drives the small water stop pad 241 to separate from the float 260, opens the water path, and makes the stored water in the drain valve to be discharged to the closestool. More specifically, when the small water stop pad 241 moves upward, the internal stored water is discharged to the closestool, the buoyancy increases, drives the float 260 to move upward to the top, at this time the water tank starts to drain, when the water source of the water tank is discharged, the float 260 loses the buoyancy due to the decrease of the water level, falls to the bottom to close the drain valve under the action of gravity, at this time the water tank and the valve rod 202 stop water inlet, the valve rod 202 falls to reset under the action of the valve rod reset spring 250 and its own gravity, at this time the small water stop pad 241 cooperates with the float 260 to seal the water path, at this time the water inlet valve starts to inlet water and continues to supplement the water source of the water tank.

[0051] In the use process, refer to the attached Figure 6As shown, after the water flow enters the water inlet of the water inlet valve, it will have two water flows, one flowing to the hydraulic button 300, and the other flowing to the water tank. When the key device 330 is pressed during the use of the toilet flushing, the water path of the hydraulic button 300 and the water path of the water tank are mixed and flushed together, thereby increasing the pressure of the impact water flow and achieving better impact effect. In the case of the same impact force, the limitation of the traditional toilet needing to be designed with larger size is avoided.

[0052] More specifically, in preferred embodiment 1, referring to the drawings attached to the specification Figure 11 and 12 As shown in preferred embodiment 2, referring to the drawings attached to the specification Figures 15-18As shown, the hydraulic button 300 opens the driving nozzle pipe 240 waterway to spray for about 4 seconds and then automatically closes, the nozzle pipe 240 flush water synchronously drives the rising of the flap cover 208 of the drain valve 200 to open, the drain valve 200 starts to drain, the high-speed water flow sprayed by the nozzle pipe 240 drives the gravity of the water tank to flush to form a siphon effect, and a fast and powerful water flow is formed to flush the toilet; The bypass waterway of the water inlet valve 100 is provided with a switching valve mechanism 600, so that when the hydraulic button 300 is opened to flush water for the first 4 seconds, the water inlet of the water inlet valve 100 only flows to the nozzle pipe 240 and does not flow into the water tank, and the water flow is concentrated to spray the nozzle pipe 240, so that the best flushing effect is brought. In the waterway of Embodiment 1, the water flow enters from the water inlet of the water inlet valve 100, flows into the drain valve 200 after the switching valve mechanism 600 and the anti-siphon vacuum breaker 500, and impacts the flushing disc 203 in the drain valve 200, so as to drive the rising of the valve rod 202, the rising of the valve rod 202 drives the rising of the flap cover 208, and the rising of the flap cover 208 realizes the opening of the water inlet passage of the water tank, so as to realize the combination of the water flow of the water tank and the water flow of the nozzle pipe 240 to form an impact water flow. When the water flow of the hydraulic button 300 stops, the valve rod 202 is reset under the action of the large reset spring 206 and the small reset spring 207, and the flap cover 208 re-seals the water inlet of the water tank water flow passage in the drain valve. In the waterway of Embodiment 2, the water flow enters from the water inlet of the water inlet valve 100, flows into the drain valve 200 after the switching valve mechanism 600 and the anti-siphon vacuum breaker 500, and impacts the flushing disc 203 in the drain valve 200, so as to drive the rising of the valve rod 202, the rising of the valve rod 202 drives the rising of the nozzle pipe 240, so as to drive the rising of the small water stop pad 241. At this time, the float 260 moves upward to the top under the action of the buoyancy, at this time, the water tank starts to drain. When the water source in the water tank is drained, the float 260 loses the buoyancy due to the drop of the water level, at this time, the float 260 falls to the bottom to close the drain valve under the action of the gravity, at this time, the water tank and the valve rod 202 stop water inlet, the valve rod 202 falls and resets under the action of the valve rod reset spring 250 and the gravity of the valve rod itself, at this time, the small water stop pad 241 also falls and resets, re-seals the waterway in cooperation with the float 260, at this time, the water inlet valve starts to inlet water, and continues to supplement the water source in the water tank.
