The driving mechanism 30 adopts a key driving mechanism or a water level driving mechanism, the key driving mechanism drives the compressing mechanism 20 to move by the pressing force applied on the key, and the water level driving mechanism drives the compressing mechanism 20 to move by the driving force generated by the water level change.
Wherein, the key driving mechanism adopts a mechanical key or an electronic key or an induction key;
in this embodiment, the water level driving mechanism includes a weight cup 31 and a lifting rod 33, the weight cup 31 is in linkage fit with the lifting rod 33, the weight cup 31 has a water inlet and a water draining small hole 311, water in the water tank enters the weight cup 31 through the water inlet, after the water level of the toilet tank drops, the weight cup 31 falls under the action of self gravity and the gravity of the water and is pressed down by the lifting rod 33 to drive the compression mechanism 20 to move, in this embodiment, the water level driving mechanism further includes a screw 32, the weight cup 31 is adjustably attached to the lower part of the screw 32, and the lifting rod 33 is in linkage fit with the screw 32 and is attached to the upper part of the screw 32.
In other embodiments, the water level driving mechanism comprises a float and a connecting rod, the float and the connecting rod are in linkage fit, and in the rising process of the water level of the toilet tank, the float floats upwards under the buoyancy action and is lifted or pressed downwards through the connecting rod to drive the compression mechanism 20 to move.
The working procedure of the detergent adding device of this embodiment is briefly described as follows:
as shown in fig. 1, in a normal state, the liquid storage chamber 10 of the present embodiment is in a relatively sealed state, that is, the liquid filling port 13 is sealed by the gland 14, at this time, the one-way valve 12 is limited at a position of opening the liquid outlet 11 under the action of the rod 141, and the liquid outlet 11 is in a normally open state, but the detergent cannot flow out from the liquid outlet 11 under the action of atmospheric pressure.
In this state, the water tank level is at the working level WL, and at this time, the water tank level is high Yu Peichong cup 31, so that the balance weight cup is filled with water.
As shown in fig. 2, when the toilet tank is drained, the water level rapidly drops to a position lower than the weight cup 31, and since the drain hole 311 of the weight cup 31 is small, the drain speed of the weight cup 31 is slower than the water level drop speed of the tank, and the water in the weight cup 31 cannot flow out instantaneously; under the action of the 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 be pressed downwards through the screw rod 32, and the lifting rod 33 presses the elastic cavity wall 23, so that the inner volume of the liquid storage cavity 10 is reduced, and the cleaning agent flows out from the liquid outlet 11 under the action of positive pressure; and thus mixes with the water of the drain passage 42 to form a cleaning solution for flushing the toilet bowl.
As shown in fig. 3, when the water in the balance weight cup 31 is discharged through the water discharge hole 311, the elastic chamber wall 23 is restored to an original state by the self restoring force and the restoring elastic member 24; the volume in the liquid storage cavity 10 is increased to form negative pressure, and at the moment, air enters the liquid storage cavity 10 through the liquid outlet 11 under the action of atmospheric pressure; because the air density is lower than the detergent density, the air stays at the upper part of the liquid storage cavity 10 beyond the detergent after entering the liquid storage cavity 10; this returns to the initial state of fig. 1 and repeats the steps of fig. 1, 2, 3.
When the cleaning agent needs to be added, as shown in fig. 4, the cleaning agent can be added into the liquid storage cavity 10 through the liquid filling opening 13 by taking out the gland 14. At this time, since the gland 14 is taken out, the rod body 141 releases the limit of the check valve 12, 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 elastic force of the second elastic member to seal the liquid outlet, so that the detergent is prevented from flowing out from the liquid outlet 11 when the detergent is added.
When the addition of the cleaning agent is completed, as shown in fig. 5, the capping 14 is reinstalled, and the lower end surface of the rod body 141 abuts against the upper end surface of the check valve 12, so that the gasket opens the liquid outlet 11, and the initial state of fig. 1 is restored.
Second embodiment:
as shown in fig. 6 to 9, the main difference between the present embodiment and the first embodiment is that: in this embodiment, the compression mechanism 20 is disposed at the lower part of the liquid storage chamber 10, in this embodiment, the water level driving mechanism includes a weight cup 31, a screw rod 32, and a lifting rod 33, the weight cup 31 is adjustably attached to the lower part of the screw rod 32, the lifting rod 33 is cooperatively engaged with the screw rod 32 and attached to the lower part of the screw rod 32, and the lifting rod 33 is located above the weight cup 31; after the water level of the toilet tank drops, the counterweight cup 31 falls under the action of gravity and drives the lifting rod 33 to lift up through the screw rod 32, and the lifting force of the lifting rod 33 drives the compression mechanism 20 to move.
In other embodiments, the compression mechanism 20 may be disposed on a side of the liquid storage chamber 10.
In this embodiment, the rod body 141 'is a filling funnel 141' that is disposed relatively independent of the gland 14, the filling funnel 141 'is movably attached to the liquid storage cavity 10, and further includes a first elastic member 16, when the gland 14 opens the filling opening 13, the filling funnel 141' moves under the action of the first elastic member 16 to release the limit of the check valve 12, and extends out from the filling opening 13, so as to facilitate filling, and in particular, the first elastic member 16 adopts a return spring.
The rest of the structure and operation of the present embodiment are similar to those of the first embodiment, and will not be described here.
