As shown in
The fluid channel 2001 communicates with the accommodating cavity 1001, the first liquid storage cavity 3002 and the second liquid storage cavity 3003 in turn, and defines the path for air and the quantitative liquid B to enter and leave the device 1000.
The sum of the volumes of the first liquid storage cavity 3002 and the second liquid storage cavity 3003 is smaller than the volume of the accommodating cavity 1001, and the second liquid storage cavity 3003 further includes a liquid storage part 3037.
The first liquid storage cavity 3002 and the second liquid storage cavity 3003 are arranged at one end of the accommodating cavity 1001. When the device 1000 pours out liquid, the quantitative liquid B stored in the second liquid storage cavity 3003 leaves the device 1000 through the fluid channel 2001, and an atmospheric low pressure area C is formed at the other end of the accommodating cavity 1001, and an atmospheric normal pressure area D is formed in the first liquid storage cavity 3002 and the second liquid storage cavity 3003.
The liquid storage part 3037 captures and stores a part of the liquid A to become a new quantitative liquid B.
When the device 1000 is reset, the quantitative liquid B stored in the second liquid storage cavity 3003 will be received and stored by the first liquid storage cavity 3002.
As shown in
The second liquid storage cavity 3003 is provided with a liquid inlet hole 3004 for allowing the liquid A to enter the second liquid storage cavity 3003, and an air outlet hole 3038 for discharging the air in the second liquid storage cavity 3003. This design can make the device back to the right time, and the liquid in the liquid storage part 3037 can smoothly enter the second liquid storage cavity 3003.
In this embodiment, the liquid inlet hole 3004 and the air outlet hole 3038 are provided as one. In other embodiments (not shown in the figures), the liquid inlet hole 3004 and the air outlet hole 3038 are not limited to one, but can also be set to two, three, four, five and any desired number.

When the device 1000 is inverted, the quantitative liquid B in the second liquid storage cavity 3003 flows out under the action of gravity; the liquid in the second liquid storage cavity 3003 falls; the second liquid storage cavity 3003 is in air communication with the first liquid storage cavity 3002, and the air pressure is the same; the liquid in the accommodating cavity 1001 falls down and forms a communication structure with the second liquid storage cavity 3003. According to the communicating vessel principle, if the air pressures of the accommodating cavity 1001 and the second liquid storage cavity 3003 are equal, the liquid levels of the accommodating cavity 1001 and the second liquid storage cavity 3003 will tend to be equal. However, at this time, the accommodating cavity 1001 is closed, and the liquid in the accommodating cavity 1001 is subjected to gravity, so that the air pressure above the liquid level of the accommodating cavity 1001 is increased. When the gravity of the liquid in the accommodating cavity 1001 is balanced with the atmospheric pressure of the second liquid storage cavity 3003, the liquid levels in the accommodating cavity 1001 and the second liquid storage cavity 3003 are balanced, and the liquid in the accommodating cavity 1001 will not flow out through the second liquid storage cavity 3003 and the first liquid storage cavity 3002.
When the device 1000 is restored to the normal state, the liquid A in the accommodating cavity 1001 falls back to the cavity bottom, and due to the atmospheric pressure, air enters the second liquid storage cavity 3003 and the accommodating cavity 1001 from the first liquid storage cavity 3002 through the air outlet hole 3038; in addition, due to the action of gravity, the liquid in the second liquid storage cavity 3003 falls back, and part of it enters the first liquid storage cavity 3002 through the liquid inlet hole 3004, forming a communicating vessel structure.
As shown in
In this embodiment, the second valve body 4000 further improves the airtightness of the device, and when the device pours liquid, the liquid in the device 1000 will not communicate with the outside world, further preventing volatilization and deterioration.
The present invention provides a quantitative liquid discharging method, which includes providing a dumping-type automatic quantitative liquid discharging device, wherein dumping-type automatic quantitative liquid discharging device comprises an accommodating cavity for accommodating liquid, a first liquid storage cavity and a second liquid storage cavity for storing quantitative liquid, and a fluid channel;
