Detailed Description
Referring to fig. 1 to 7, an intelligent tank 10 is used to supply water to an intelligent cleaning assembly, and a flush tank 20 is used to supply water to flush a toilet bowl.
The anti-siphon device comprises a water inlet pipe 30, an outer sleeve 40 and a blocking cover 60, wherein the outer sleeve 40 is sleeved with the water inlet pipe 30 in an inner-outer mode, a water outlet channel 50 is formed between the outer sleeve 40 and the water inlet pipe 30, namely, outside water is introduced from the water inlet pipe 30 and then communicated with the water outlet channel 50. The blocking cover 60 is disposed on the top of the outer sleeve 40, and an air blocking section 70 is formed between the upper opening of the water inlet pipe 30 and the top wall of the blocking cover 60. That is, there is a certain distance between the top end of the water inlet pipe 30 and the blocking cover 60, and the two are not in contact with each other, when water enters, the blocking cover 60 blocks the water sprayed from the water inlet pipe 30, and after the water naturally falls down, the water enters the water outlet channel 50 between the water inlet pipe 30 and the outer sleeve 40. The bottom of the outer sleeve 40 is provided with a water inlet 41 and a water outlet 42, the water inlet 41 is in butt joint with the lower end opening of the water inlet pipe 30, the water outlet 42 is in butt joint with the water outlet channel 50, and the water outlet 42 is communicated with the intelligent water tank 10. Therefore, when water enters, the water sequentially passes through the water inlet pipe 30, the air separation section 70 and the water outlet passage 50 to reach the intelligent water tank 10. The side wall of the outer sleeve 40 is provided with a through hole 43, and the through hole 43 is communicated with the air separation area 70, so that the air separation area 70 is communicated with the external atmosphere. When water is normally fed, the through hole 43 does not discharge water. The through hole 43 is arranged at the position close to the outer side, so that water falling after being blocked by the blocking cover 60 can be prevented from entering the through hole 43, the opening at the outer side of the through hole 43 can be higher, and the water can not overflow from the through hole 43 when water normally enters.
If negative pressure occurs in the water inlet pipe 30, because the air isolation section 70 can be isolated from the outside atmosphere, a closed communicating body cannot be formed between the water inlet pipe 30 and the water outlet passage 50, and therefore no siphon occurs. In addition, if the inlet valve does not work properly, excess water may overflow from the through hole 43 after the water outlet passage 50 is filled with water.
Preferably, the head of the outer sleeve 40 is wide at the top and narrow at the bottom, the through hole 43 opens at the head of the outer sleeve, and the through hole 43 is located below the opening at the upper end of the water inlet pipe 30. The head of the outer sleeve 40 is actually a conical structure, and the side wall of the inner cavity is tapered downward, which is advantageous for guiding water flow into the water outlet channel 50 and avoiding water flow out of the through hole 43. Further preferably, a portion of the top wall of the blocking cover 60 opposite to the water inlet pipe 30 has an arc shape protruding upward.
Preferably, a cap 90 is further included, and the cap 90 is fastened to the head of the outer sleeve 40 to cover the blocking cover 60.
Preferably, the positioning ring 32 is arranged around the water inlet pipe 30, the inner wall of the outer sleeve 40 is provided with a positioning step surface 44, the positioning ring 32 leans against the positioning step surface 44, and the inner wall of the outer sleeve 40 is provided with a latch 45 to fasten the positioning ring 32.
Preferably, the water inlet 41 is disposed on the bottom surface of the outer sleeve 40, and the water outlet 42 is disposed on the side surface of the outer sleeve 40. The intelligent water tank 10 is provided with a water inlet nozzle 11, a water outlet nozzle 12 and a mounting sleeve 13, the mounting sleeve 13 is arranged on the top surface of the intelligent water tank 10, and the outer sleeve 40 is connected with the mounting sleeve 13 in an inserting mode. The bottom of the mounting sleeve 13 is provided with a first connecting channel 14 and a second connecting channel 15, the first connecting channel 14 is connected with the water inlet nozzle 11 and the water inlet 41 (the water inlet 41 is inserted into the first connecting channel 14), and the second connecting channel 15 is connected with the water outlet 42 and the inner cavity of the intelligent water tank 10. Therefore, the external water enters the inlet pipe 30 from the inlet nozzle 11, and then enters the smart water tank 10 through the second connection channel 15 after exiting from the outlet channel 50.
Preferably, a snap structure is provided between the side wall of the outer sleeve 40 and the inner wall of the mounting sleeve 13, which can be fastened together. In this embodiment, the fastening structure on the outer wall of the outer sleeve 40 is a protruding block, and the fastening structure on the inner wall of the mounting sleeve 13 is a clamping groove, so that the protruding block and the clamping groove can be fastened or unlocked by rotating the outer sleeve 40 during disassembly and assembly.
Preferably, the through hole 43 opens into the top of the flush tank 20. Thus, water overflowing through the through hole 43 enters the flush tank 20. In this embodiment, the inside of the flushing water tank 20 is divided into an installation chamber 22 by a partition plate 21, a part of the bottom surface of the flushing water tank 20 opposite to the installation chamber 22 is hollowed out, the intelligent water tank 10 is located below the flushing water tank 20, the outer sleeve 40 extends into the installation chamber 22 and extends to the top of the installation chamber 22, and the through hole 43 of the outer sleeve 40 extends laterally and crosses the partition plate 21.
