A flushing pipe 2 and a water outlet 5 are arranged in the toilet body 6. Water flows around the flushing pipe 2 and flushes downward, and finally the sewage is flushed away from the water outlet 5.

[0036] A flushing system can be applied to the above-mentioned toilet, including a water outlet device 1 and a water tank 7, the water outlet device 1 includes a water inlet part and a water outlet part; the water inlet part includes a water inlet pipe 107, a nozzle 108 and a water replenishing assembly, water is inletted at one end of the water inlet pipe 107, and a nozzle 108 is provided at the other end, the water replenishing assembly is installed between the nozzle 108 and the water outlet part, and the water replenishing assembly is connected to the water tank 7.

[0037] In this embodiment, the water outlet part includes a water outlet pipe 105 and a threaded connector 106. Water enters from the water inlet pipe 107 and then passes through the nozzle 108. The water flow nozzle 108 squeezes and accelerates, forming a certain negative pressure on the lower side of 105. At this time, the water replenishment component will drive the water in the water tank 7 to enter the water outlet pipe 105. The water in the water inlet pipe 107 attracts the water in the water replenishment component through the nozzle 108 and flushes through the water outlet part.

[0038] In this embodiment, the water tank 7 is located in the installation groove 3, the water tank 7 is equipped with a water outlet pipe 105 and is connected to the flushing pipe 2, a recessed platform 102 is provided on the water tank 7, the upper side of the water outlet pipe is located on the recessed platform 102, the water outlet part also includes a threaded connector 106, the first end of the threaded connector 106 is connected to the water outlet pipe 105, and the second end is connected to the flushing pipe 2, and the installation groove 3 is also equipped with a secondary water tank, which is connected to the water tank 7. The secondary water tank can be disassembled as needed, and a nozzle 108 is provided on the lower side of the water tank 7, the nozzle 108 is opposite to the lower end of the water outlet pipe 105, the inner diameter of the nozzle 108 is smaller than the water outlet pipe 105, and a gap is left between the lower end of the water outlet pipe 105 and the upper end of the nozzle 108. In the present embodiment, the upper end surface of the nozzle 108 is flush with the inner bottom surface of the water tank 7, and the water outlet pipe 105 also leaves a gap with the bottom surface of the water tank 7. This gap is used to replenish water from the water tank 7 to the water outlet pipe 105. This gap is the water replenishment component in the present embodiment. The water in the water tank 7 can flow out of the water outlet pipe 105. A water inlet pipe 107 is arranged on the lower side of the nozzle 108. In the present embodiment, the water inlet pipe 107 is connected to the water tank 7. A booster pump 110 is installed on the first end of the water inlet pipe 107. A connecting port 109 is arranged at the input end of the booster pump 110. The booster pump 110 and the connecting port 109 are both arranged in the water tank 7. A grid support rod (such as Fig.12), and these structures are arranged inside the water tank. The noise generated when the booster pump is started will be isolated by water, and the noise can be further reduced by water. The booster pump is arranged inside the water tank and connected to the nozzle, and water is directly pumped from the water tank and sprayed from the nozzle. This can reduce the influence of water pressure on flow and increase flow, and can also wrap the booster pump and nozzle with water to minimize the noise generated during flushing. In other embodiments, the booster pump 110 can also be installed outside the water tank 7 (such as Figure 4 When flushing is needed, the booster pump 110 is turned on to send the water in the water tank 7 into the water inlet 105 for flushing.

[0039] In this embodiment, the distance between the upper end of the nozzle 108 and the lower end of the water outlet pipe 105 is between 0mm-20mm, the water pressure is 0.14Mpa, and the water level in the water tank is 240mm. At this time, the maximum instantaneous flow rate of the outlet of the side water outlet pipe 105 is 2L / s, and the average flow rate for 3s is 1.95L / s. This flow rate reaches 1.93L / s, which is a qualified flow rate. Obviously, the flow rate of this data fully meets the requirements for use.

[0040] Through the solution of this embodiment, the water tank 7 is installed in the toilet body 6 to reduce the size of the space occupied by the entire toilet, and the water in the water tank 7 is driven to flush into the toilet body 6 through the Venturi effect, thereby increasing the flow rate and improving the flushing effect. At the same time, maintaining a distance between the water outlet pipe 105 and the nozzle 108 can make the flushing flow larger and the flushing effect better.

[0041] In this embodiment, the water tank 7 is equipped with a delayed water inlet 101, which controls the water inlet into the water tank 7. The delayed water inlet 101 adopts a common water inlet on the market. Through the above technical solution, the delayed water inlet into the water tank 7 can be controlled, and water can be added after the flushing is completed, which will not affect the flushing effect.

The nozzle 108 is set at a position deviating from the axis of the water inlet pipe 107, and gradually shrinks from bottom to top. Compared with other shapes of drain outlets, the opening shape in this embodiment has the largest flow rate and the best flushing effect. Under a pressure of 0.24Mpa, the flow rate at the outlet of the side water outlet pipe 105 of this shape of nozzle is 6-7L / 3s, which fully meets the standard flow rate of 5.79 / 3s. Fig.10 , Fig.11 As shown, the dotted line part is the moving area after the water leaves the nozzle. Fig.10 The nozzle 108 in the prior art is circular in shape. The sprayed water gradually disperses after leaving the nozzle 108, and the impact force decreases rapidly. Fig.11 The nozzle 108 of this embodiment is specifically crescent-shaped, and the water sprayed out will not diverge, but always maintain a concentrated flow, with a stronger impact force, and can better drive the water flow to improve the flushing effect.

[0043] When flushing is needed, open the valve, and the water in the water tank 7 passes through the pressurized water inlet pipe 107 of the booster pump 110 and is sprayed toward the water outlet pipe 105 through the nozzle 108, and finally enters the flushing pipe 2 through the threaded connector 106 for flushing. During the process, the water in the water tank 7 will be driven into the water outlet pipe 105, and the flushing will follow. During the flushing process, the water in the water tank 7 will not be replenished. After the flushing is completed, the delayed water inlet 101 will replenish the water in the water tank 7 through the tap water pipe.

[0047] The water outlet part includes a water outlet pipe 105 and a threaded connector 106. Water enters from the water inlet pipe 107 and then passes through the nozzle 108. The water flow nozzle 108 squeezes and accelerates, forming a certain negative pressure on the lower side of 105. At this time, the water replenishment component will drive the water in the water tank 7 to enter the water outlet pipe 105. The water in the water inlet pipe 107 attracts the water in the water replenishment component through the nozzle 108 and flushes through the water outlet part.

[0048] In this embodiment, the water tank 7 is located in the installation groove 3, and a water outlet pipe 105 is installed outside the water tank 7 and is connected to the flushing pipe 2. The water outlet also includes a threaded connector 106, and the first end of the threaded connector 106 is connected to the water outlet pipe 105, and the second end is connected to the flushing pipe 2.

The auxiliary water tank can be disassembled according to needs, the water inlet pipe 107 is directly fixedly connected to the water outlet pipe 105, and the inner diameter of the nozzle 108 is smaller than that of the water outlet pipe 105. In the present embodiment, a circular hole is provided on the side of the bottom of the water tank, and a connecting pipe 112 is fixedly installed at the circular hole. The connecting pipe 112 is connected to the bottom end of the water outlet pipe 105. The connecting pipe 112 is the water replenishment component of the present embodiment. The water in the water tank 7 can flow out of the water outlet pipe 105. A water inlet pipe 107 is provided on the lower side of the nozzle 108. In the present embodiment, the water inlet pipe 107 is directly connected to the tap water pipe. The scheme in Example 1 can also be adopted, which is not drawn in the figure: the water inlet pipe 107 is connected to the water tank 7, and a booster pump 110 is installed on the first end of the water inlet pipe 107. A connecting port 109 is provided at the input end of the booster pump 110. The booster pump 110 and the connecting port 109 are both arranged in the water tank 7. A grid support rod (such as Fig.12 ), and at the same time, these structures are arranged inside the water tank, and a booster pump is arranged inside the water tank and connected to the nozzle, and water is directly pumped from the water tank and sprayed from the nozzle, which can reduce the influence of water pressure on flow and increase flow, and can also wrap the booster pump and nozzle by water to minimize the noise generated during the flushing process. In other embodiments, the booster pump 110 can also be installed outside the water tank 7 (such as Figure 4 When flushing is needed, the booster pump 110 is turned on to send the water in the water tank 7 into the water inlet 105 for flushing.

[0051] In this embodiment, the water tank 7 is equipped with a delayed water inlet 101, which controls the water inlet into the water tank 7. The delayed water inlet 101 adopts a common water inlet on the market. Through the above technical solution, the delayed water inlet into the water tank 7 can be controlled. Since the nozzle 108 and the delayed water inlet 101 are both connected to the tap water pipeline, the water inlet from the two openings at the same time will inevitably reduce the flushing pressure. Therefore, the delayed water inlet 101 controls the delayed water inlet, and waits until the flushing is completed before filling the water, which will not affect the flushing effect.

The nozzle 108 is set at a position deviating from the axis of the water inlet pipe 107, and gradually shrinks from bottom to top. Compared with other shapes of drain outlets, the opening shape in this embodiment has the largest flow rate and the best flushing effect. Under a pressure of 0.24Mpa, the flow rate at the outlet of the side water outlet pipe 105 of this shape of nozzle is 6-7L / 3s, which fully meets the standard flow rate of 5.79 / 3s. Fig.10 , Fig.11 As shown, the dotted line part is the moving area after the water leaves the nozzle. Fig.10 The nozzle 108 in the prior art is circular in shape.

Fig.11 The nozzle 108 of this embodiment is specifically crescent-shaped, and the water sprayed out will not diverge, but always maintain a concentrated flow, with a stronger impact force, and can better drive the water flow to improve the flushing effect.

[0053] When flushing is needed, open the valve, and tap water passes through the water inlet pipe 107 and the nozzle 108 to spray toward the water outlet pipe 105, and finally enters the flushing pipe 2 through the threaded connector 106 for flushing. During the process, the water in the water tank 7 will be driven into the water outlet pipe 105, and then the flushing will be carried out. During the flushing process, the water tank 7 will not be replenished with water. After the flushing is completed, the delayed water inlet 101 will replenish the water in the water tank 7 through the tap water pipe.

Since the nozzle 108 and the delayed water inlet 101 are both connected to the tap water pipeline, the water inlet from the two openings at the same time will inevitably reduce the flushing pressure. Therefore, the delayed water inlet 101 controls the delayed water inlet, and waits until the flushing is completed before filling the water, which will not affect the flushing effect.

[0062] In this embodiment, two connecting ears 103 are fixedly mounted on the water tank 7, and two mounting holes 4 are arranged at the edge of the toilet body 6, and the mounting holes 4 and the connecting ears 103 are matched and fixed.

[0063] When flushing is needed, open the valve, and tap water passes through the water inlet pipe 107 and the nozzle 108 to spray toward the water outlet pipe 105, and finally enters the flushing pipe 2 through the threaded connector 106 for flushing. During the process, the water in the water tank 7 will be driven into the water outlet pipe 105, and then the flushing will be carried out. During the flushing process, the water tank 7 will not be replenished with water. After the flushing is completed, the delayed water inlet 101 will replenish the water in the water tank 7 through the tap water pipe.

[0064] Embodiment 4

[0065] like Figure 8 , Fig. 9 A toilet shown in the figure comprises a flushing system and a toilet body 6, a mounting groove 3 is arranged on the rear side of the toilet body 6, a plurality of mounting holes 4 are arranged on the edge of the mounting groove 3, a flushing pipe 2 and a water outlet 5 are arranged inside the toilet body 6, water flows around the flushing pipe 2 and flushes downward, and finally the sewage is flushed away from the water outlet 5.

[0066] A flushing system can be applied to the above-mentioned toilet, including a water outlet device 1 and a water tank 7. The water outlet device 1 includes a water inlet part and a water outlet part. The water inlet part includes a water inlet pipe 107, a nozzle 108 and a water replenishing assembly. Water is inletted at one end of the water inlet pipe 107, and a nozzle 108 is provided at the other end. The water replenishing assembly is installed between the nozzle 108 and the water outlet part. The water replenishing assembly is connected to the water tank 7. The water outlet part includes a water outlet pipe 105 and a threaded connector 106. Water enters from the water inlet pipe 107 and then passes through the nozzle 108. The water flow nozzle 108 squeezes and accelerates, forming a certain negative pressure on the lower side of 105. At this time, the water replenishing assembly will drive the water in the water tank 7 to enter the water outlet pipe 105. The water in the water inlet pipe 107 attracts the water in the water replenishing assembly through the nozzle 108 and flushes through the water outlet.

[0067] In this embodiment, the water tank 7 is located outside the installation groove 3, and the water outlet pipe 105 is located inside the installation groove. The water tank 7 located outside is more convenient for modification and maintenance. The water outlet also includes a threaded connector 106, the first end of the threaded connector 106 is connected to the water outlet pipe 105, and the second end is connected to the flushing pipe 2. A secondary water tank can be installed on one side of the water tank 7, and the secondary water tank is connected to the water tank 7. The secondary water tank can be disassembled according to demand, the water inlet pipe 107 is directly fixedly connected to the water outlet pipe 105, and the inner diameter of the nozzle 108 is smaller than the water outlet pipe 105. In the present embodiment, a circular hole is provided on the side of the bottom of the water tank, and a connecting pipe 112 is fixedly installed at the circular hole. One end of the connecting pipe 112 is connected to the bottom end of the water outlet pipe 105, and the other end is connected to the water outlet pipe 105. The connecting pipe 112 is the water replenishment component of the present embodiment. The water in the water tank 7 can flow out of the water outlet pipe 105 through the water replenishment component. A water inlet pipe 107 is provided on the lower side of the nozzle 108. In the present embodiment, the water inlet pipe 107 is directly connected to the tap water pipe. The scheme in Example 1 can also be adopted. The figure does not show: the water inlet pipe 107 is connected to the water tank 7, and a booster pump 110 is installed on the first end of the water inlet pipe 107. A connecting port 109 is provided at the input end of the booster pump 110. The booster pump 110 and the connecting port 109 are both arranged in the water tank 7. A grid support rod (such as Fig.12 ), a booster pump is arranged inside the water tank and connected to the nozzle, water is directly pumped from the water tank and sprayed from the nozzle, which can reduce the influence of water pressure on flow and increase flow, and can also wrap the booster pump and nozzle by water to minimize the noise generated during flushing. In other embodiments, the booster pump 110 can also be installed outside the water tank 7 (such as Figure 4 ), when flushing is needed, the booster pump 110 is turned on to send the water in the water tank 7 into the water inlet 105 for flushing.

[0068] The inner channel of the nozzle 108 is thick at the lower end and thin at the upper end. The nozzle 108 is located at an eccentric position close to the inner wall of the water outlet. The nozzle 108 is an eccentric flat opening. The nozzle is close to the inner wall of the water outlet pipe 105. The flat opening of the nozzle 108 is specifically a crescent-shaped opening or an elliptical opening. The nozzle 108 is set at a position deviating from the axis of the water inlet pipe 107, and gradually narrows from bottom to top. Compared with other shapes of drain outlets, the opening shape in this embodiment has the largest flow rate and the best flushing effect. Under a pressure of 0.24Mpa, the flow rate at the outlet of the side water outlet pipe 105 of this shape of nozzle is 6-7L / 3s, which fully meets the standard flow rate of 5.79 / 3s, such as Fig.10 , Fig.11 As shown, the dotted line part is the moving area after the water leaves the nozzle. Fig.10 The nozzle 108 in the prior art is circular in shape. The sprayed water gradually disperses after leaving the nozzle 108, and the impact force decreases rapidly. Fig.11The nozzle 108 of this embodiment is specifically crescent-shaped, and the water sprayed out will not diverge, but always maintain a concentrated flow, with a stronger impact force, and can better drive the water flow to improve the flushing effect.

[0069] In this embodiment, the distance between the upper end of the nozzle 108 and the lower end of the connecting pipe 112 is between 0 mm and 20 mm. The water pressure is 0.14 MPa, and the water level in the water tank is 240 mm.

[0070] In this embodiment, the water tank 7 is equipped with a delayed water inlet 101, which controls the water inlet into the water tank 7. The delayed water inlet 101 adopts a common water inlet on the market. Through the above technical solution, the delayed water inlet into the water tank 7 can be controlled. Since the nozzle 108 and the delayed water inlet 101 are both connected to the tap water pipeline, the water inlet from the two openings at the same time will inevitably reduce the flushing pressure. Therefore, the delayed water inlet 101 controls the delayed water inlet, and waits until the flushing is completed before filling the water, which will not affect the flushing effect.

[0071] When flushing is needed, open the valve, and tap water passes through the water inlet pipe 107 and the nozzle 108 to spray toward the water outlet pipe 105, and finally enters the flushing pipe 2 through the threaded connector 106 for flushing. During the process, the water in the water tank 7 will be driven into the water outlet pipe 105, and then the flushing will be carried out. During the flushing process, the water tank 7 will not be replenished with water. After the flushing is completed, the delayed water inlet 101 will replenish the water in the water tank 7 through the tap water pipe.

[0072] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
