Detailed Description
The embodiments illustrated herein will enable those skilled in the art to more fully understand the present invention, without limiting it in any way, when the present invention is described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 7, the utility model discloses a water tank pump towards system, including base 1, water tank 2, water supply connector 3, water intaking valve 4, solenoid valve 5, stand-by power supply 6, water pump 7, venturi generator 8, face towards pipeline 91 and help towards pipeline 92. The water tank 2 is fixed on the base 1, the water inlet joint 3 is connected with a tap water pipe, and tap water is divided into three paths of water to be respectively supplied to a toilet seat cover plate (not shown), a water inlet valve 4 and a water pump 7. The water inlet valve 4 is used for controlling water inlet of the water tank 2, the water pump 7 is fixed on the base 1 outside the water tank 2, the venturi generator 8 is arranged in the water tank, the water outlet end 71 of the water pump 7 is connected with the venturi generator 8, the water outlet end of the venturi generator is divided into two outlets which are respectively connected to the flushing pipeline 91 and the flushing assisting pipeline 92, and the flushing pipeline 91 and the flushing assisting pipeline 92 are respectively used for flushing and assisting flushing of the toilet.
The venturi generator 8 comprises a water inlet pipe 81 and a water outlet pipe 82, the inlet end of the water inlet pipe 81 is connected with the water outlet end 71 of the water pump, the outlet end of the water inlet pipe 81 is a nozzle with a diameter smaller than that of the inlet end, the water outlet pipe 82 is sleeved outside the outlet end of the water inlet pipe 81, the inlet diameter of the water outlet pipe is larger than that of the outlet end of the water inlet pipe 81, the water outlet pipe 82 is provided with a gradually-changed inward-contracting section at the downstream of the nozzle, the pipe wall of the gradually-changed inward-contracting section is provided with a water inlet 821, under the action of the venturi effect, water flowing out from the nozzle rapidly drives. The water inlet pipe 81 may be integrally formed on the plastic water tank 2, or may be separately formed and then fixed to the bottom surface of the water tank 2. The tap water pressurized by the water pump 7 absorbs the water in the water tank through the venturi generator 8, the water in the water tank is mixed with the tap water, the flushing flow is increased, the flushing kinetic energy is increased, and the defect of insufficient potential energy of the low water tank is overcome. The water pump 7 is supplied with water by a tap water pipe, the water pump 7 can be arranged outside the water tank 2, the water pump 7 does not need to be soaked in water, the reliability of a product is improved, meanwhile, the sealing requirement of the water pump 7 is reduced, and the manufacturing cost of the water pump 7 is reduced. The water pump 7 sets up the volume that reduces water tank 2 outside the water tank, and on the other hand, the water that causes the venturi effect is provided by the water pipe, and rivers in the reducible water tank further reduce water tank 2's volume, are favorable to realizing the miniaturization of toilet bowl product.
The standby power supply is electrically connected with the electromagnetic valve 5, when the power supply of the system is abnormal, the standby power supply supplies power to the electromagnetic valve 5, the electromagnetic valve 5 is opened when water needs to be flushed, the water pump 7 does not play a role in pressurization at the moment and is only used for passing water, and even if the water pump 7 does not work, flowing tap water can also drive water in the water tank to flow into the water outlet pipe 82. In the traditional structural scheme that water is supplied from the water tank 2 when the water is fed into the water pump 7, the water pump 7 does not work when power supply is abnormal, no flowing water causes a venturi effect, and the water cannot be flushed when power failure occurs. Even adopt stand-by power supply, because the restriction in toilet bowl space, stand-by power supply's volume and power are all less, and the power that the water pump required is greater than stand-by power supply's power far away, so stand-by power supply can't supply power to the water pump, just can't form the venturi effect when the power supply is unusual.
The normal flushing process of the system power supply: the electromagnetic valve 5 and the water pump 7 are opened, tap water enters the water inlet pipe 81 of the venturi generator 8 after being pressurized by the water pump 7, is rapidly sprayed out from the nozzle to cause the venturi effect, so that water in the water tank flows into the water outlet pipe 82 of the venturi generator 8, the tap water and the water in the water tank are mixed, and the water is divided into two paths at the outlet of the venturi generator 8 and is respectively used for surface flushing and flushing assisting.
Flushing process with abnormal system power supply: the stand-by power supply supplies power to the electromagnetic valve 5 to open the electromagnetic valve 5, tap water enters the water inlet pipe 81 of the venturi generator 8 through the water pump 7, at the moment, the water pump 7 only plays a role of water passing, and because the tap water has certain water pressure, the flowing tap water is jetted from the nozzle to cause the venturi effect, so that water in the water tank is absorbed to flow into the water outlet pipe 82 of the venturi generator, the tap water and the water in the water tank are mixed, and the outlet of the venturi generator is divided into two paths which are respectively used for surface flushing and auxiliary flushing.
Above embodiment only is for explaining the utility model discloses a technical thought can not be injectd with this the utility model discloses a protection scope, all according to the utility model provides a technical thought, any improvement of doing on technical scheme basis and equal replacement all fall into within the protection scope of the utility model.
