Technical Field

[0001] The utility model relates to the field of bathrooms, and in particular to a flushing structure, a flushing system and a toilet. Background Art

[0002] The existing smart toilet with a separate plastic water tank realizes zero water pressure flushing, and often adopts a water inlet valve at the bottom of the water tank to fill the water. For example, the existing document (CN115162472A) discloses a hybrid integrated valve and toilet flushing system and toilet, which uses a water pump water tank and tap water two water channels to achieve zero water pressure flushing by a water pump when there is electricity, and uses a super capacitor to drive a motor to achieve tap water flushing when there is no electricity. However, its water tank inlet valve also adopts bottom water inlet (such as Figure 1 As shown in the figure, the water tank 1' needs to leave a space 11' for the water inlet valve and the connecting hose installation at the bottom, which occupies the water tank space. At the same time, the flushing assembly needs to be set at a high place to meet the flood control suction and water level requirements, and the water inlet level of the water inlet valve is at the bottom, which requires the connection between the two to be connected through a longer hose, and the connection between the flushing assembly and the waterway needs to be connected with another hose. In this way, two hoses are needed, and these two hoses are directly connected to the waterway and need to withstand the high pressure of the waterway, so they need to use pressure-resistant braided hoses, which brings about the problem of high cost.

[0003] In view of this, the applicant in this case conducted an in-depth study on the above-mentioned issues and proposed a flushing structure, a flushing system and a toilet, which resulted in this case. Utility Model Content

[0004] The purpose of the utility model is to provide a flushing structure, a flushing system and a toilet to overcome the above-mentioned existing problems. No space needs to be left at the bottom of the water tank. Only one pressure-resistant braided hose is needed to realize a two-way water inlet flushing mode. The utility model has the characteristics of simple structural design and low cost.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0006] A flushing structure comprises a water inlet valve assembly, a flushing assembly and a three-way assembly; two channels of the three-way assembly are a first water outlet channel and a second water outlet channel which are arranged horizontally side by side, the first water outlet channel is directly connected to the water inlet of the water inlet valve assembly, and the second water outlet channel is directly connected to the water inlet of the switch valve of the flushing assembly; the third channel of the three-way assembly is a water inlet channel, which is connected to a water inlet hose.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] This case involves a scouring structure, such as Figure 2-5 As shown, the figure gives a schematic diagram of the application state of the new flushing structure in the flushing system. The flushing structure includes an inlet valve assembly 1, a flushing assembly 2 and a three-way assembly 3. Two channels of the three-way assembly 3 are a first water outlet channel 31 and a second water outlet channel 32 arranged horizontally side by side. The first water outlet channel 31 is directly connected to the inlet water path 11 of the inlet valve assembly 1, and the second water outlet channel 32 is directly connected to the switch valve inlet water path 21 of the flushing assembly 2. The third channel of the three-way assembly 3 is a water inlet channel 33, and the water inlet channel 33 is connected to the water inlet hose 4. The water inlet hose 4 is directly connected to the tap water path and withstands the high pressure of the water path. The water inlet hose 4 adopts a pressure-resistant braided hose. Tap water enters from the water inlet channel 33, and then supplies water to the water tank through the first water outlet channel 31 and the water inlet valve assembly 1, and provides tap water path flushing water to the flushing assembly 2 through the second water outlet channel 32, thereby realizing the two-way water inlet flushing mode of the water tank and the tap water path.

[0029] The new flushing structure uses a three-way assembly 3 to design the water inlet valve assembly 1 as a side water inlet valve structure located on the side of the flushing assembly 2, and the two are arranged side by side at a high position. In the system layout, the water inlet valve assembly 1 and the flushing assembly 2 are respectively placed on the inner and outer left and right sides of the upper end of the water tank, which fully shortens the distance between the two, and the overall structural design is very simple and compact. In this way, there is no need to make space at the bottom of the water tank for the installation of the water inlet valve assembly 1. At the same time, only a pressure-resistant braided water inlet hose 4 needs to be connected to the water inlet channel 33 of the three-way to realize the two-way water inlet flushing mode. Compared with the existing need for two pressure-resistant braided hoses, the new type brings about the effect of reducing costs.

[0030] Preferably, the water inlet valve assembly 1 has a valve cavity 12 connected to the water inlet valve water inlet path 11, and a water inlet valve anti-siphon unit 13 is provided at the upper end of the valve cavity 12. The water inlet valve assembly 1 is provided with an atmospheric port connected to the valve cavity 12, and the atmospheric port is controlled to be opened and closed by the water inlet valve anti-siphon pad of the water inlet valve anti-siphon unit 13. When water flows into the valve cavity 12 from the water inlet valve water inlet path 11, the water inlet valve anti-siphon pad can be quickly driven to move upward to close the atmospheric port, and when the water inlet valve water inlet path 11 stops discharging water, the anti-siphon pad automatically falls down by its own weight. In this way, when negative pressure appears in the water inlet channel 33 connected to the tap water path, the water inlet valve anti-siphon unit 13 can be used to effectively avoid the problem that the water in the water tank may be sucked back into the water inlet channel 33.

[0031] Preferably, the flushing assembly 2 has a chamber 22 connected to the switch valve water inlet 21, and the upper end of the chamber 22 is provided with a switch valve anti-siphon unit 23. The flushing assembly 2 is provided with an atmospheric port connected to the chamber 22, and the atmospheric port is controlled to be opened and closed by the switch valve anti-siphon pad of the switch valve anti-siphon unit 23. When water flows into the chamber 22 from the switch valve water inlet 21, it can quickly drive the switch valve anti-siphon pad to move upward to close the atmospheric port, and when the switch valve water inlet 21 stops discharging water, the anti-siphon pad automatically falls down by its own weight. Similarly, when negative pressure appears in the water inlet channel 33 connected to the tap water, the switch valve water inlet 21 can be used to effectively avoid the problem that the water in the flushing assembly 2 may be sucked back into the water inlet channel 33.

[0032] Preferably, the three-way assembly 3 and the flushing assembly 2 are designed as an integrated structure. Specifically, the three-way assembly 3 is a structural assembly that is integrated with the body of the switch valve water inlet 21 of the flushing assembly 2. This can simplify the structure, reduce structural connections, and improve structural tightness.

[0033] Preferably, the flushing assembly 2 includes a water pump switching valve, a switch switching valve 25, a brush ring pipe 26 and a main flushing pipe 27. The water pump switching valve connects the water pump water inlet, the water pump brush ring water outlet and the water pump main flushing water outlet 24, the water pump brush ring water outlet is connected to the brush ring pipe 26, and the water pump main flushing water outlet is connected to the main flushing pipe 27. The water tank water pump provides water to enter the water pump water inlet, and the water pump switching valve drives and controls the water inlet to connect to the water pump brush ring water outlet or the water pump main flushing water outlet 24, thereby realizing the water outlet switching control of the brush ring pipe 26 or the main flushing pipe 27 in the water pump water tank water inlet mode. The switch switching valve 25 connects the switch valve water inlet, the tap water brush ring water outlet 251 and the tap water main flushing water outlet 252, the tap water brush ring water outlet 251 is connected to the brush ring pipe 26, and the tap water main flushing water outlet 252 is connected to the main flushing pipe 27. Tap water enters from the water inlet of the switch valve, and the inlet is driven and controlled by the switch switching valve 25 to connect to the tap water brush ring outlet 251 or the tap water main flush outlet 252, thereby realizing the water outlet switching control of the brush ring pipe 26 or the main flush pipe 27 under the tap water water inlet mode.

[0034] The main flushing waterway 24 of the water pump and the main flushing waterway 252 of the tap water are both connected to the main flushing pipe 27. Preferably, a swing rod automatic switching unit 28 is provided at the connecting intersection. The swing rod automatic switching unit 28 includes a swing rod shaft and a swing rod member. The swing rod member swings freely around the swing rod shaft and can swing to a state of blocking the main flushing waterway 24 of the water pump or a state of blocking the main flushing waterway 252 of the tap water. In this way, when the main flushing waterway 24 of the water pump discharges water, the water pressure is used to drive the swing rod member to block the main flushing waterway 252 of the tap water; when the main flushing waterway 252 of the tap water discharges water, the water pressure is used to drive the swing rod member to block the main flushing waterway 24 of the water pump, thereby preventing the problem of mutual flow between the two water outlet waterways.

[0035] The present application also provides a flushing system, such as Figure 2-5 As shown, it includes a water tank 5, a water pump assembly 6 and a flushing structure as described above. The flushing structure is installed at the upper end of the water tank 5, the water inlet valve assembly 1 is arranged on the inner side of the upper end of the water tank 5, and the flushing assembly 2 and the three-way assembly 3 are arranged on the outer side of the upper end of the water tank 5. The water pump assembly 6 is connected between the water tank outlet 51 of the water tank 5 and the water pump water inlet of the flushing assembly 3. In addition, in order to prevent the siphon effect, a water pump pressurization anti-siphon unit 61 is also provided at the upper end of the water pump water inlet. In the structural layout of the novel flushing system, the water inlet valve assembly 1 and the flushing assembly 2 are respectively placed on the inner and outer left and right sides of the upper end of the water tank 5, which fully shortens the distance between the two, and the overall structural design is very simple and compact. There is no need to make space at the bottom of the water tank 5 to ensure the water capacity of the water tank. At the same time, only a pressure-resistant braided water inlet hose needs to be connected to realize the two-way water inlet flushing mode, which is low in cost.

[0036] Preferably, a through hole 52 is provided at the upper end of the water tank 5 , and the water inlet valve assembly 1 and the three-way assembly 3 located inside and outside the water tank 5 , respectively, are directly connected inside and outside through the through hole 52 .

[0037] The present invention also provides a toilet, including a toilet body, in which a flushing system is arranged, and similarly, the two-way water inlet flushing mode is achieved without the need for a water tank to make room, and the structure is simple and compact, and the cost is low.
