[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0022] See also Figures 1 to 4 As shown, an embodiment of the utility model provides a flushing device for a toilet.

[0023] Specifically, the flushing device 1 is fixed in the toilet, and a cavity 11 is provided in the flushing device 1, and a push rod 12 is provided in the cavity 11; one end of the push rod 12 is a first end, and the other end is a second end; the first end can pass through the inner wall of the cavity 11 and can slide relative to the cavity 11, and an elastic member 13 is provided between the second end and the inner wall of the cavity 11 close to the first end, and the side of the second end away from the elastic member 13 forms a push cavity 14 with the inner wall of the cavity; the flushing device 1 is provided with a water inlet pipe 15 and a drain hole 16, and the push cavity 14, the water inlet pipe 15 and the drain hole 16 are connected to each other; the first end of the push rod 12 can open or close the flushing valve 5 of the toilet by sliding.

[0024] The flushing device of the present invention injects water into its interior through the water inlet mechanism 2, causing the second end of the push rod in the push chamber 14 to begin sliding under the action of water pressure, pushing the first end of the push rod 12 to slide relative to the flushing device 1. This sliding action of the first end of the push rod 12 can open or close the toilet flush valve 5. When the flush is complete, the water inlet mechanism 2 stops supplying water. Under the action of the elastic member 13 and the drainage hole 16, the first end of the push rod 12 gradually returns to its original position, closing the toilet flush valve 5. Compared with the existing technology, this device has a simpler structure and higher adaptability, can provide sufficient driving force, and has lower waterproof performance requirements.

[0025] Preferably, the cross-sectional area of ​​the drainage hole 16 is smaller than the cross-sectional area of ​​the water inlet pipe 15. This structure can ensure that the water injection speed of the water inlet pipe 15 is greater than the drainage speed of the drainage hole 16, thereby improving the reaction speed of the top rod 12.

[0026] More preferably, the drainage hole 16 is provided on the inner wall of the water inlet pipe 15, and the radius of the drainage hole 16 is 20-50% of the radius of the water inlet pipe 15. When the radius of the drainage hole 16 is less than 20% of the radius of the water inlet pipe 15, the drainage speed will be affected, thereby affecting the return speed of the push rod 12; when the radius of the drainage hole 16 is greater than 50% of the radius of the water inlet pipe 15, the drainage hole 16 is too large, which will affect the water filling speed of the push chamber 14.

[0027] Preferably, a water inlet channel 123 is provided in the ejector rod 12, and the water inlet channel 123 is connected to the pushing chamber 14. The provision of the water inlet channel 123 can increase the force-bearing area of ​​the ejector rod 12. Under the same water pressure, the larger the force-bearing area of ​​the ejector rod 12, the greater the pressure generated, making the ejection speed of the ejector rod 12 faster.

[0028] Preferably, the angle between the axial direction of the push rod 12 and the axial direction of the water inlet pipe 15 is 45-90 degrees. The angle between the axial direction of the push rod 12 and the water inlet pipe 15 facilitates the connection between the flushing device 1 and the water inlet mechanism 2.

[0029] Preferably, the push rod 12 includes a rod body 121 and a pushing portion 122, and the pushing portion 122 has a larger cross-sectional area than the rod body 121;

[0030] An elastic member 13 is disposed between the side of the pushing portion 122 close to the rod 121 and the inner wall of the cavity 11. The side of the pushing portion 122 away from the elastic member 13 forms the pushing cavity 14 with the inner wall of the cavity 11. A sealing ring 17 is disposed on the outer side of the pushing portion 122, which abuts against the inner wall of the cavity 44. The sealing ring 17 is disposed on the outer side wall of the pushing portion 122 to prevent water injected into the pushing cavity 14 from passing over the pushing portion.

[0031] Preferably, the elastic member 13 is a compression spring, and the elastic member 13 is sleeved on the rod body 121 . Both ends of the elastic member 13 abut against the inner wall of the cavity 11 and the pushing portion 122 respectively.

[0032] Correspondingly, the present invention further provides a toilet, comprising the flushing device 1 described above, wherein the water inlet pipe 15 of the flushing device is connected to the water inlet mechanism 2 of the toilet.

[0033] It should be noted that the water inlet mechanism 2 includes a toilet water inlet valve and an on-off valve assembly. The toilet water inlet valve can realize automatic water inlet and automatic water shut-off functions. The on-off valve assembly is connected to the toilet controller, and the two ends of the on-off valve assembly are respectively connected to the toilet water inlet valve and the water inlet pipe 15 of the flushing device 1. When flushing is required, the on-off valve assembly can be controlled to open to connect the toilet water inlet valve and the water inlet pipe. Due to the change in the pressure differential within the toilet water inlet valve, the water pressure of the tap water causes the toilet water inlet valve to automatically fill with water, thereby supplying water to the flushing device 1. The water will flow along the pipeline to the water inlet pipe 15. Under the action of the tap water pressure, the push rod 12 is pushed upward. The first end of the push rod 12 can slide to open or close the toilet flush valve 5.

[0034] In another embodiment of the present invention, see Figure 4As shown, the water inlet mechanism 2 can also be a water pump, which is connected to the toilet controller to control its operation. When flushing is required, the water pump can deliver tap water to the water inlet pipe 15. Under the action of the tap water pressure, the push rod 12 is pushed upward. The first end of the push rod 12 can slide to open or close the toilet flush valve 5.

[0035] Preferably, see Figure 3 and Figure 4 As shown, the flushing device 1 is fixed to the push rod of the water tank button 3 of the toilet, and the first end of the push rod 12 can abut the outer edge of the water tank button 3 when sliding. In a specific implementation, when the water inlet mechanism 2 injects water into the flushing device 1, the first end of the push rod 12 slides relative to the flushing device 1 under the action of water pressure, and the first end abuts the outer edge of the water tank button 3 or the inner wall of the water tank. Under the continuous water pressure, the push rod clamped by the flushing device 1 moves downward until it contacts the flush valve 5 of the toilet and opens.

[0036] More preferably, clamping parts 18 are provided on both sides of the outer wall of the flushing device 1 , and the clamping parts 18 are clamped with the pushing rod, and the two clamping parts 18 are fastened by fasteners 4 .

[0037] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
