The working principle and the working process of the embodiment are briefly described as follows:
when the soap dispenser 30 is not placed on the base 10, the valve core 51 of the first opening and closing valve keeps closing the inlet of the inner cavity 31 of the soap dispenser under the action of the reset elastic element 52 of the first opening and closing valve, so that the soap liquid in the inner cavity 31 of the soap dispenser is prevented from flowing out; the valve core 61 of the second opening and closing valve keeps closing the liquid outlet end 112 of the liquid supply channel 11 under the action of the reset elastic piece 62 of the second opening and closing valve, so that the soap liquid in the liquid storage bottle 20 is prevented from flowing out.
Referring to fig. 20 to 22, in this case, in a state that the soap dispenser 30 is placed on the base 10 and the soap dispenser 30 is not pressed, the abutting surface 411 of the upper surface of the top wall of the piston 41 abuts and matches with the lower surface of the bottom wall of the soap dispenser 30, so that the valve core 61 of the second opening and closing valve opens the liquid outlet end 112 of the liquid supply channel 11, the valve core 51 of the first opening and closing valve opens the inlet of the inner cavity 311 of the soap dispenser, and the inner cavity 311 of the soap dispenser is communicated with the liquid outlet end 112 of the liquid supply channel 11.
Referring to fig. 23 to 25, in the state of fig. 20, when the soap dispenser 30 is pressed downward, the main body 31 of the soap dispenser 30 moves downward, that is, the piston 41 moves upward relative to the main body 31 of the soap dispenser, the piston 41 presses the air in the inner cavity 311 of the soap dispenser, and since the plug 80 is in the falling position at this time to open the air outlet hole 32, the air in the inner cavity 311 of the soap dispenser can be sequentially discharged from the air outlet hole 32 and the air outlet check valve 321, and since the movable seat 90 compresses the movable seat return elastic member 91 under the elastic force of the piston return elastic member 42 at this time to cause the first air inlet check valve 331 to close the air inlet hole 33, the air is not discharged from the air inlet hole 33.

After the piston 41 is reset to the proper position, because the elastic force applied to the movable seat 90 by the piston resetting elastic member 42 is insufficient or eliminated, the movable seat 90 moves downward under the elastic force of the movable seat resetting elastic member 91, so that the first air inlet check valve 331 can be opened to allow the outside air to enter from the air inlet hole 33 to replenish the inner cavity 311 of the soap dispenser.
When the soap liquid in the inner cavity 311 of the soap dispenser is not filled to the position that the plug 80 floats, the plug 80 is in the falling position and keeps opening the vent hole 32, so that the soap dispenser 30 can be pressed for multiple times to continue liquid filling; until the interior 311 of the dispenser is filled to a position where the cap 80 floats, the cap 80 floats and closes the vent 32, thereby preventing further depression of the dispenser 30, indicating that the interior 311 of the dispenser is filled, and the dispenser 30 can be removed from the base 10 for use. After the soap dispenser 30 is detached from the base 10, the valve core 51 of the first opening/closing valve automatically closes the inlet of the inner cavity 31 of the soap dispenser 30 under the action of the return elastic member 52 of the first opening/closing valve, so as to prevent the soap in the inner cavity 31 of the soap dispenser from flowing out, and the valve core 61 of the second opening/closing valve automatically closes the liquid outlet end 112 of the liquid supply channel 11 under the action of the return elastic member 62 of the second opening/closing valve, so as to prevent the soap in the liquid supply channel 11 from flowing out.
In the present embodiment, the first opening/closing valve seat 53 is not provided, and the valve body 51 of the first opening/closing valve and the return elastic member 52 of the first opening/closing valve are directly attached to the piston 41. As shown in fig. 16 and 17, the second opening/closing valve seat 63 of the present embodiment is fixedly attached to the liquid outlet end 112 of the liquid supply passage 11. In addition, the support seat 43, the support seat return elastic element 44, the throat 121, the check valve 70, etc. are not provided in the second embodiment, the piston cavity 12 is not formed on the base 10, and other structures not described above are substantially the same as those in the first embodiment, and are not described herein again.
