one side of the partition 300 is detachably connected with the water tank 100, and the partition 300 is provided with a notch 310 matched with the tank cover 130; the regulating box 500 is arranged at the notch 310 and is detachably connected with one side, far away from the water tank 100, of the partition plate 300, the bottom wall of the regulating box 500 is provided with a supporting structure 510, the supporting structure 510 is used for supporting the sealing assembly 150, the sealing assembly 150 moves upwards to expose the second water outlet 131, the inner cavity of the water tank 100 is communicated with the inner cavity of the regulating box 500 to form a cavity, the side wall of the regulating box 500 is provided with a constant pressure structure 530, and the constant pressure structure 530 is used for balancing the air pressure and the external air pressure of the cavity.

With the above arrangement, the water tank 100 is inverted, and then the cover 130 is connected to the first water outlet 110 of the bottom wall of the water tank 100. At this time, the sealing assembly 150 without any external force is attached to the second water outlet 131 formed in the case cover 130 to seal. And then the water tank 100 is mounted on one side of the partition 300, the regulating tank 500 is mounted on the other side of the partition 300, and the abutting structure 510 in the regulating tank 500 can pass through the notch 310 formed in the partition 300 and exert an upward force on the sealing assembly 150, so that the sealing assembly 150 moves upward to expose the second water outlet 131.

It should be noted that, the tank cover 130 is not only connected to the first water outlet 110, but also communicates with the inner cavity of the water tank 100 through the first water outlet 110. Therefore, when the second water outlet 131 is exposed, the inner cavity of the regulating tank 500 communicates with the inner cavity of the water tank 100 to form a chamber. In addition, the lateral wall of the regulating tank 500 is provided with a lateral pressure structure communicating with the outside, so that the external air pressure and the air pressure of the chamber can be balanced, thereby ensuring that the liquid in the water tank 100 stops flowing downward when the liquid level in the regulating tank 500 rises to the end of the tank cover 130 near the abutting structure 510.

In detail, as shown in fig. 1, 6 and 7, the sealing assembly 150 includes a movable column 151, an elastic member 153 and a sealing sheet 155. The movable column 151 is used for moving upwards under the action of the supporting structure 510; the elastic member 153 is sleeved on the movable column 151; the sealing piece 155 is connected with one end of the movable column 151 near the second water outlet 131, and the sealing piece 155 is used for sealing or exposing the second water outlet 131 under the driving of the movable column 151.

When no external force is applied, the elastic member 153 acts on the movable column 151, so that the sealing piece 155 connected to the movable column 151 can be closely adhered to the second water outlet 131. When an external force is applied, that is, when the abutting structure 510 acts on the movable column 151, the elastic member 153 is compressed, and the movable column 151 is upwardly moved by the upward force, so that the sealing sheet 155 is driven to upwardly move to expose the second water outlet 131, at this time, a distance exists between the sealing sheet 155 and the second water outlet 131, the inner cavity of the regulating tank 500 is communicated with the inner cavity of the water tank 100, and thus the liquid in the water tank 100 flows down into the regulating tank 500.

To further avoid liquid spillage, the sealing plate 155 is a water silicone plate. It should be noted that the silica gel has excellent water repellency, and the water-stop silica gel sheet is selected as the sealing sheet 155, so that the economical efficiency of the product is ensured, and the better sealing property of the product is ensured.

Further, the sealing assembly 150 further includes a first fastener for connecting the sealing plate 155 with the movable post 151. Based on the arrangement, the sealing piece 155 and the movable column 151 can be ensured not to fall off or loose when being moved under the action of external force; meanwhile, under the action of no external force, the sealing piece 155 is ensured to be stably sealed when being attached to the second water outlet 131, and the second water outlet 131 is not inclined or swayed.

Further, as shown in fig. 6 and 7, the cover 130 further includes a stopper 133, and the stopper 133 is used to limit the movement of the movable pillar 151 in the vertical direction. In detail, the stopper 133 may be provided as a U-shaped block having a cavity adapted to the outer wall of the movable column 151, so that the movable column 151 can stably move upward, thereby smoothly driving the sealing sheet 155 to open the second water outlet 131.

Optionally, as shown in fig. 2, the abutment structure 510 is an abutment post. The supporting column is disposed on the bottom wall of the adjusting box 500 and can be coaxially disposed with the movable column 151, so as to ensure that the supporting column can smoothly support and act on the movable column 151, that is, apply an upward force to the movable column 151.

As an alternative embodiment, as shown in fig. 3, the constant pressure structure 530 includes a vent pipe 531 and a check valve 533, the vent pipe 531 is in communication with the cavity of the regulating tank 500, the check valve 533 is located in the cavity of the vent pipe 531, and the check valve 533 is used to control the external airflow to enter the cavity of the regulating tank 500 in one direction.

With the above arrangement, the check valve 533 can control the air flow to enter the regulating tank 500 from the air pipe 531 in one direction. When the water tank 100 is mounted on the partition 300, that is, when the abutting structure 510 of the adjusting tank 500 acts on the sealing assembly 150, the adjusting tank 500 is communicated with the water tank 100 through the second water outlet 131, so that air flows into a cavity formed by communicating an inner cavity of the water tank 100 with an inner cavity of the adjusting tank 500, and the liquid is prevented from overflowing to one side of the check valve 533 while the balance between the cavity and the external air pressure is realized. In detail, the check valve 533 is a duckbill valve.

In an alternative embodiment, the charging device further comprises a second fastener for connecting the adjustment tank 500 with the partition 300. Based on the above-described fastening connection, a relatively stable arrangement of the adjusting box 500 and the partition 300 is ensured.

In an alternative embodiment, as shown in fig. 1, the filling device further comprises a base 700, the base 700 is detachably connected to a side of the partition 300 adjacent to the regulating tank 500, and the base 700 is provided with a receiving chamber 710 for receiving the regulating tank 500.

Taking this embodiment as an example, the working flow and working principle of the liquid adding device are as follows:

before the filling device is used, at this time, the water tank 100 is separated from the partition 300, the water tank 100 is turned upside down, the cover 130 is loosened, water is filled from the first water outlet 110, and then the cover 130 is connected to the first water outlet 110 of the bottom wall of the water tank 100. At this time, the sealing assembly 150 without any external force is attached to the second water outlet 131 formed in the cover 130 to seal, and no water leakage occurs when the water tank 100 is tilted or positioned.

And then the water tank 100 is mounted on one side of the partition 300, the regulating tank 500 is mounted on the other side of the partition 300, and the abutting structure 510 in the regulating tank 500 can pass through the notch 310 formed in the partition 300 and exert an upward force on the sealing assembly 150, so that the sealing assembly 150 moves upward to expose the second water outlet 131, and the liquid in the water tank 100 then flows into the regulating tank 500 from the gap between the sealing assembly 150 and the second water outlet 131. At this time, the bubble in the water tank 100 was observed to be emitted, which means that the installation was correct and that the liquid was smoothly flowing down.

After a while, when the liquid level in the regulating tank 500 rises to a level where the tank cover 130 approaches to one end of the abutting structure 510, the air pressure of the chamber formed by the communication between the inner chamber of the water tank 100 and the inner chamber of the regulating tank 500 balances with the air pressure outside, the liquid stops flowing downward, and the liquid level in the regulating tank 500 keeps high.

When the filling device is in use, the liquid in the regulating tank 500 is continuously consumed. The pressure balance structure 530 is disposed at one side of the regulating tank 500, and controls the air flow to enter the regulating tank 500 in one direction and then enter the water tank 100, so as to balance the air pressure of the chamber with the air pressure of the outside. Therefore, when the liquid level of the regulating tank 500 drops below the bottom wall of the tank cover 130, the liquid in the water tank 100 again starts to flow downward, and at this time, bubbles in the water tank 100 continuously start to emerge again.

After the filling device is used, once the cover 130 is separated from the partition 300 mounted with the regulating box 500, the movable column 151 returns downward under the action of the elastic member 153, so that the sealing sheet 155 is attached to the second water outlet 131, and the water tank 100 is sealed. Therefore, water tank 100 can be directly removed regardless of whether there is or not there is liquid in the inner cavity of water tank 100. It should be noted that, the water tank 100 is a large-capacity water tank 100, and can be used smoothly without adding water a plurality of times.

In summary, an embodiment of the present utility model discloses a liquid feeding device including a water tank 100, a partition 300, and an adjusting tank 500. Wherein water tank 100 includes a tank cover 130 and a seal, and an adjustment direction is provided with a holding structure 510 and a lateral pressure structure. The liquid feeding device improves the structure and optimizes the assembly while preventing the overflow of the liquid in the water tank 100. On the one hand, the liquid adding device enhances the integration of the water tank 100 and the tank cover 130, and prevents dust and dust; on the other hand, it ensures that the water tank 100 and the regulating tank 500 are integrally sealed, thereby ensuring sanitary safety of water quality and easy use.
