Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

Example one

As shown in fig. 1-9, a low water tank toilet bowl comprises a toilet bowl body 1, and a bowl 11 is arranged on the toilet bowl body 1. The bottom of the urinal 11 is provided with a submerged inlet 111, and the submerged inlet 111 is connected with a sewage siphon 112. The toilet bowl 11 has a cleaning pipe 101 for cleaning the peripheral wall thereof at the top and a jet pipe 102 for flushing a submerged bay 111 at the bottom. The side of the urinal 11 is provided with a water tank 12, the lower part of the water tank 12 sinks into the toilet bowl body 1, the highest liquid level of the water tank is higher than the scrubbing pipeline 101, and the bottom of the water tank 12 is provided with a drain valve 2.

A reservoir 10 is arranged below the water tank 12 in the toilet bowl body 1, and a bottom water outlet of the water discharge valve 2 is communicated with the reservoir 10. One end of the brush duct 101 communicates with the reservoir 10 through a brush water supply auxiliary pipe 103, and one end of the spray duct 102 communicates with the reservoir 10 through a spray water supply auxiliary pipe 104. Preferably, the brushing water feeding auxiliary pipe 103 and the spraying water feeding auxiliary pipe 104 are extended downward into the reservoir 10, respectively, and the brushing water feeding auxiliary pipe 104 is extended into the bottom of the reservoir 10. Preferably, the water inlet of the jet water delivery auxiliary pipe 104 is higher in level than the water inlet of the brush water delivery auxiliary pipe 103.

Preferably, in order to ensure that the flushing water quantity can flush the peripheral wall of the urinal 11, the horizontal height difference H between the water inlet of the flushing and water delivering auxiliary pipe 103 and the water inlet of the jetting and water delivering auxiliary pipe 104 should satisfy the following relation: h is more than V/S. Wherein V is the volume of the water volume demand for washing the urinal 11, and S is the sectional area of the auxiliary washing and water delivery pipe 103.

The brushing pipe 101 is an annular pipe with closed side edges, and a plurality of flushing holes 105 facing the peripheral wall of the urinal 11 are uniformly distributed at the bottom of the annular pipe along the circumferential direction. The bottom of the dropping urinal 11 is provided with a jet orifice 106 at the position opposite to the orifice of the sewage siphon 112, and the bottom end of the jet pipe 102 is connected with the jet orifice 106.

The drain valve 2 is a cylindrical drain valve, an overflow pipe 20 is fixedly arranged on the side edge of the drain valve 2, a completely through overflow channel 200 is arranged in the overflow pipe 20, and two ends of the overflow channel 200 are respectively communicated with the water tank 12 and the water outlet of the base of the drain valve 2. An overflow means 21 for isolating external air is fixedly installed at the upper portion of the overflow pipe 20, and an overflow cap 22 for preventing generation of vortex is fixedly installed at the top of the overflow pipe 20. A water replenishing pipeline 220 which is communicated up and down is arranged in the overflow cap 22, a water inlet valve 3 is arranged in the water tank 12, the water inlet valve 3 is provided with a water replenishing pipe 30, and one end of the water replenishing pipe 30 is fixedly inserted into the water replenishing pipeline 220.

The principle of the embodiment is as follows: after the drain valve 2 is opened, the water in the tank 12 flows out through the outlet of the valve base and into the reservoir 10. Since the bottom of the brushing water feeding auxiliary pipe 103 is lower than the bottom of the jet water feeding auxiliary pipe 104, when the water level in the reservoir 10 reaches the water inlet position of the brushing water feeding auxiliary pipe 103, the water in the reservoir 10 is preferentially supplied to the brushing water feeding auxiliary pipe 103. Since the highest water level of the water tank 12 is higher than the position of the brushing pipe 101, the water with high water level and high potential energy in the water tank 12 flows into the brushing pipe 101 through the brushing water delivery auxiliary pipe 103, and is finally sprayed out from the plurality of washing holes 105 to clean the peripheral wall of the toilet bowl 11 first, so as to ensure the brushing effect.

The first case: the difference H between the horizontal height of the water inlet of the brushing water conveying auxiliary pipe 103 and the horizontal height of the water inlet of the spraying water conveying auxiliary pipe 104 is small. The water in the reservoir 10 is preferentially supplied to the auxiliary brushing water pipe 103, and when the water level in the reservoir 10 reaches the water inlet of the auxiliary jet water pipe 104, the water in the reservoir 10 simultaneously enters the brushing pipe 101 and the jet pipe 102 from the auxiliary brushing water pipe 103 and the auxiliary jet water pipe 104, respectively, so that the peripheral wall and the bottom of the urinal 11 can be cleaned simultaneously.

The second case: the difference H between the horizontal height of the water inlet of the brushing water delivery auxiliary pipe 103 and the horizontal height of the water inlet of the spraying water delivery auxiliary pipe 104 is large. The water in the reservoir 10 is preferentially supplied to the brushing water delivery auxiliary pipe 103, and since the liquid level in the early stage of the reservoir 10 does not reach the position of the water inlet of the jet water delivery auxiliary pipe 104, the water with high water level and high potential energy in the water tank 12 is totally injected into the brushing pipe 101 from the brushing water delivery auxiliary pipe 103 and is finally jetted out from the plurality of flushing holes 105 to clean the peripheral wall of the toilet bowl 11 first. When the water level of the reservoir 10 reaches the water inlet of the auxiliary water spraying and conveying pipe 104, the remaining water in the reservoir 10 will completely enter the spraying pipe 102 through the auxiliary water spraying and conveying pipe 104, and finally be sprayed out from the spraying opening 106 to flush the submerged bay 111.

In this embodiment, the water in the reservoir 10 can be reasonably distributed to the brushing channel 101 and the injection channel 102 by controlling the diameters of the brushing water supply auxiliary pipe 103 and the injection water supply auxiliary pipe 104.

In the present embodiment, by installing the overflow means 21 on the upper portion of the overflow pipe 20 of the drain valve 2, the overflow means 21 isolates the injection pipe 102 from the external air through the overflow path 200. The water of the reservoir 10 isolates the spray pipe 102 from the outside air through the brush pipe 101. Therefore, when the water discharge valve 2 discharges water, because the air pressure in the injection pipeline 102 is smaller than the air pressure of the outside air, the injection pipeline 102 can be pre-stored with water after the water is flushed each time, and when the bottom of the toilet is flushed next time, the pre-stored water in the injection pipeline 102 can directly act on the siphon pipeline 112, so that the stroke of water is saved, and the flushing effect can be greatly improved.

Example two

As shown in fig. 10 to 13, the present embodiment differs from the first embodiment only in that: the scrubbing pipeline 101 is an annular water guide groove with an opening at the inner side, and a first rotary punching jet orifice 107 communicated with the annular water guide groove is arranged on the side wall of the reservoir 10. A circle of water conveying pipeline 108 is arranged on the outer side of the annular water diversion groove, and a brushing water inlet 109 communicated with the reservoir 10 is arranged on one side of the water conveying pipeline 108 close to the first rotary-flushing jet opening 107. The water pipe 108 is provided with a second rotary flushing jet orifice 110 communicated with the annular water guide groove on the opposite side of the brushing water inlet 109, and the direction of the second rotary flushing jet orifice 110 is the same as the flow direction of flushing water of the annular water guide groove. The rest of the structure of the present embodiment is the same as that of the first embodiment.

In this embodiment, the water in the reservoir 10 enters the annular water guiding groove through the brushing and water-transporting auxiliary pipe 103, and is finally ejected from the first ejection opening 107 and the second ejection opening 110, and the ejected water is guided by the annular water guiding groove to clean the peripheral wall of the urinal 11. The directions of the first rotary-blow jet orifice 107 and the second rotary-blow jet orifice 110 are the same as the flow direction of the flushing water of the annular water guide groove, the flushing water at the two sides flows along the same direction of the water flow, the peripheral wall of the urinal 11 is flushed in a spiral manner, and the flushing effect is good. The rest of the principle of the embodiment is the same as that of the first embodiment.
