As shown in fig. 5, 6 and 7, in the present embodiment, the liquid feeding mechanism 40 includes a liquid feeding tube forming the liquid feeding channel, the power assisting mechanism includes a receiving cup 60 forming the power assisting channel, the receiving cup 60 has an air vent 61 communicating with the outside, and the liquid feeding tube is in sealed communication with the liquid storage mechanism 10; the liquid feeding pipe is communicated with the receiving cup 60 through the through hole 411, the air vent 61 is higher than the through hole 411, gas is stored at the upper part of the liquid feeding pipe, so that the water level in the receiving cup 60 is higher than the water level in the liquid feeding pipe, the liquid storage mechanism 10 adds the cleaning agent into the liquid feeding pipe, the water pressure in the receiving cup 60 provides assistance for the discharge of the cleaning liquid in the liquid feeding pipe, and in the drainage process of the toilet water tank, the liquid level in the liquid feeding pipe is lower than the water level of the toilet water tank, so that the toilet is flushed in advance. Preferably, the air vent 61 is higher than the working water level WL1 of the toilet water tank.
In this embodiment, the liquid feeding pipe includes an upper liquid feeding pipe 41 and a lower liquid feeding pipe 43 which are communicated with each other, the lower liquid feeding pipe 43 is connected to or integrally formed with the receiving cup 60 in a sealing manner, the through hole 411 is disposed on the upper liquid feeding pipe 41, and the lower liquid feeding pipe 43 is connected to the drainage passage 51 in a sealing manner. In this embodiment, the receiving cup 60 is sleeved outside the upper liquid feeding pipe 41.
The working process of the detergent adding device of the embodiment is briefly described as follows:
in a normal state, the liquid storage mechanism 10 of the present embodiment is in a relatively sealed state, that is, the liquid filling port 13 is sealed by the gland 14, and the liquid outlet 11 is in a normally open state, but the cleaning agent cannot flow out of the liquid outlet 11 under the action of atmospheric pressure. In this state, the tank water level is at the operating water level WL1, and the tank water level is higher than the weight cup 31, so that the weight cup 31 is filled with water.
As shown in fig. 3, when the toilet tank drains, on one hand, the water level of the tank slowly drops to be lower than the top of the weight cup 31, and since the drain hole 311 of the weight cup 31 is smaller, the drainage speed of the weight cup 31 is slower than the drop speed of the water level of the tank, the water in the weight cup 31 cannot instantly run out; under the action of the self gravity of the balance weight cup 31 and the gravity of water in the cup, the balance weight cup 31 drives the lifting rod 33 to press down through the screw 32, the lifting rod 33 presses the elastic diaphragm 23 to deform, so that the internal volume of the liquid storage mechanism 10 is reduced, and the cleaning agent flows out of the liquid outlet 11 under the action of positive pressure and flows into the upper liquid supply pipe 41; on the other hand, after the drainage mechanism is opened, the lower liquid supply pipe 43, the upper liquid supply pipe 41 and the receiving cup 60 form a communicating vessel with the inner cavity of the toilet water tank through the drainage channel 51, and the water level in the receiving cup 60 is kept to be basically consistent with the water level of the water tank; because the through hole 411 of the upper liquid supply pipe 41 is opened at a lower position, when the liquid is not passed through the through hole 411, the liquid level in the upper liquid supply pipe 41 does not rise any more under the action of the gas in the upper liquid supply pipe 41, and the liquid level in the receiving cup 60 continues to rise, therefore, the liquid level of the upper liquid supply pipe 41 is lower than the liquid level of the receiving cup 60, and the water pressure in the receiving cup 60 provides assistance to the liquid in the upper liquid supply pipe 41; so that the detergent can be mixed with water discharged from the water tank in advance, thereby reducing the residue of the detergent and improving the cleaning effect.
Finally, when the water in the weight cup 31 completely flows through the drain hole 311, the elastic diaphragm 23 is restored to the initial state under the action of the self-restoring force and the restoring elastic member 24; the volume in the liquid storage mechanism 10 is increased to form negative pressure, and at the moment, under the action of atmospheric pressure, air enters the liquid storage mechanism 10 through the air vent 61 and the liquid outlet 11; because the density of the air is lower than that of the cleaning agent, the air enters the liquid storage mechanism 10 and then crosses the cleaning agent to stay at the upper position of the liquid storage mechanism 10; thus, the initial state of fig. 1 is restored, and the steps of fig. 1, 2 and 3 are repeated.
When the detergent needs to be added, the gland 14 is removed, and the detergent can be added into the liquid storage mechanism 10 through the liquid adding opening 13. At this time, since the gland 14 is taken out, the check valve 12 is automatically switched from the normally open state to the sealing state, and the sealing gasket of the check valve 12 is tightly attached to the liquid outlet 11 under the action of the spring to seal the check valve, so that the detergent is prevented from flowing out of the liquid outlet 11 when the detergent is added.
When the detergent is added, the gland 14 is reinstalled, and the lower end face of the gland 14 abuts against the upper end face of the one-way valve 12, so that the sealing gasket opens the liquid outlet 11 and returns to the initial state of fig. 1.
Second embodiment:
as shown in fig. 8 and 9, the main difference between the present embodiment and the first embodiment is that: the liquid feeding channel in this embodiment is an overflow channel communicated with the drain valve base, and may be an independent channel separately provided independently from the overflow channel, and the independent channel is communicated with the drain valve base, where the boosting mechanism in this embodiment includes a piston element 60a, and the piston element 60a is matched with the liquid feeding mechanism 40 to form a piston cavity; during the water discharge of the toilet tank, the air pressure in the piston chamber provides an assisting force for discharging the cleaning liquid in the liquid feeding mechanism 40, and the liquid level of the cleaning liquid in the liquid feeding mechanism 40 is lower than the water level of the toilet tank under the action of the piston element 60a, so that most of the cleaning liquid in the liquid feeding mechanism 40 is discharged to the water discharge channel 51 before the water tank finishes the water discharge.
In this embodiment, the piston element 60a cooperates with the feed channel to form a piston chamber. Wherein the piston element 60a can be actuated by a mechanical switch, an electronic switch or an inductive switch.
The working process of this embodiment is briefly described as follows:
as shown in fig. 8, when the drainage mechanism 50 is opened, the detergent is dropped into the liquid feed passage; when the water tank is opened, the liquid feeding channel and the inner cavity of the water tank form a communicating vessel through the drainage channel 51, and the water level in the liquid feeding channel is kept to be basically consistent with the water level of the water tank; the detergent is mixed with water in the liquid feed passage and stays at an upper end position of a water level of the liquid feed passage.
As shown in fig. 9, during the water discharging process, the external force is increased by the driving of the mechanical switch, the electronic switch or the inductive switch, and the piston element 60a is pushed to make the water level in the liquid feeding channel lower than the water level of the water tank, so that the detergent can be mixed with the water discharged from the water tank in advance, and the effect of flushing the toilet bowl is achieved.
The rest of the structure and the operation process of this embodiment are basically similar to those of the first embodiment, and are not described herein again.
