[0028] Example 1

[0029] Reference below Figures 1 to 3The invention relates to an automatic liquid replenishing device, comprising a first liquid storage container 1, a second liquid storage container 2 and an automatic sealing component 3. The first liquid storage container 1 comprises a first liquid outlet 4, and the second liquid storage container 2 comprises a second liquid outlet 5. The first liquid storage container 1 is provided with a first liquid outlet 4 which is communicated with the second liquid storage container 2. The second liquid storage container 2 is replenished with liquid, and the second liquid storage container 2 discharges liquid from the second liquid outlet 5. The automatic sealing component 3 is connected to the first liquid storage container 1. The automatic sealing component 3 seals / opens the first liquid outlet 4 according to the liquid level in the second liquid storage container 2. It should be noted that the first liquid storage container 1 and the second liquid storage container 2 can be stacked or independently arranged. When the first liquid storage container 1 and the second liquid storage container 2 are stacked, the first liquid outlet 4 and the second liquid storage container 2 are connected. When the containers 2 are stacked, the first liquid storage container 1 can be placed above the second liquid storage container 2, and the automatic sealing component 3 is connected to the bottom of the first liquid storage container 1 and is arranged in the second liquid storage container 2. The automatic sealing component 3 is in direct contact with the liquid in the second liquid storage container 2; when the first liquid storage container 1 and the second liquid storage container 2 are set independently, the first liquid storage container 1 is placed on one side of the second liquid storage container 2, and the liquid in the second liquid storage container 2 is introduced into the first liquid storage container 1. When the liquid level in the second liquid storage container 2 changes, the liquid in the first liquid storage container 1 also changes accordingly. The automatic sealing component 3 is connected to the inside of the first liquid storage container 1, and the liquid replenishment process is implemented according to the amount of liquid introduced from the second liquid storage container 2 to the first liquid storage container 1.

[0030] Furthermore, the automatic sealing assembly 3 at least includes a buoyancy portion 31, a connecting rod 32 and a sealing member 33. One end of the connecting rod 32 is movably connected to the first liquid storage container 1. The buoyancy portion 31 and the sealing member 33 are both fixed on the connecting rod 32. The sealing member 33 and the buoyancy portion 31 are both arranged on the outside of the first liquid storage container 1 and are close to or away from the first liquid outlet 4 at the same time. As a preferred embodiment, the sealing member 33 has the same movement direction as the buoyancy portion 31, and the installation position of the sealing member 33 matches the first liquid outlet 4. In this embodiment, the left end of the connecting rod 32 is movably connected to the first liquid storage container 1, and the buoyancy portion 31 is used to sense the liquid level and adjust its position according to the liquid level. When the height of the buoyancy portion 31 changes up and down with the liquid level, the buoyancy portion 31 drives the sealing member 33 to move up and down through the connecting rod 32, and the installation position of the sealing member 33 matches the position of the first liquid outlet 4. When the liquid level in the first liquid storage container 1 rises, the position of the buoyancy part 31 is driven to rise, that is, the position of the sealing member 33 is driven to rise, thereby being able to seal the first liquid outlet 4, achieving the effect of stopping the liquid discharge, wherein the buoyancy of the liquid in the second liquid storage container 2 on the automatic sealing component 3 is greater than the sum of the weight of the automatic sealing component 3 itself and the pressure of the liquid discharged from the first liquid outlet 4 on the automatic sealing component 3. When the liquid is discharged from the second liquid outlet 5, the liquid level drops, the height of the buoyancy part 31 drops, and the position of the sealing member 33 drops, thereby opening the seal of the first liquid outlet 4. After the sealing member 33 is opened, there is no component blocking the opening of the first liquid outlet 4, which is easy to discharge liquid with higher viscosity, and the sealing member 33 does not extend into the first liquid outlet 4, which also avoids adhesion and ensures smooth liquid discharge. As a preferred embodiment, a plurality of weight-reducing holes can be provided on the connecting rod 32 to reduce the weight of the connecting rod 32 and reduce the required buoyancy.

[0031] It should be noted that, as a preferred embodiment, the first liquid storage container 1 is arranged on the upper part of the second liquid storage container 2, and the automatic sealing component 3 is arranged at the bottom of the first liquid storage container 1. The liquid in the first liquid storage container 1 can fall directly into the second liquid storage container 2 by gravity. The automatic sealing component 3 seals the first liquid outlet 4 as the liquid level changes, thereby facilitating the outflow of the liquid.

[0032] It should be noted that, as a preferred embodiment, referring to Figure 3The automatic sealing assembly 3 also includes a rotating shaft 6. The mounting portion 11 is connected to one end of the connecting rod 32 through the rotating shaft 6. The rotating shaft 6 is a shaft used to support rotating parts and only bear bending moments but not transmit torque. It is used to transmit rotation. The mounting portion 11 is provided at the bottom of the first liquid storage container 1. The rotating shaft 6 rotatably connects the mounting portion 11 to the bottom of the first liquid storage container 1. The rotating shaft 6 and the connecting rod 32 provide guidance for the up and down movement of the seal 33. The buoyancy portion 31 and the seal 33 are provided on one side of the rotating shaft 6 to ensure that the movement directions of the buoyancy portion 31 and the seal 33 are the same. The seal 33 moves away from the first liquid outlet 4 as the liquid level of the second liquid storage container 2 moves downward, further avoiding obstruction of the liquid outflow from the first liquid outlet 4.

[0033] It should be noted that, as a preference, the buoyancy portion 31 is arranged at the other end of the connecting rod 32, and the seal 33 is arranged between the buoyancy portion 31 and the rotating shaft 6, and is located on the side of the connecting rod 32 close to the rotating shaft 6. The connecting rod 32 rotates at the position of the rotating shaft 6. Therefore, on the connecting rod 32, the torque of the buoyancy portion 31 is greater than the torque of the seal 33, reducing the influence of the liquid out of the first liquid outlet 4 on the pressure of the seal 33, and further ensuring that the buoyancy of the liquid in the second liquid storage container 2 on the automatic sealing assembly 3 is greater than the weight of the automatic sealing assembly 3 itself plus the pressure of the liquid out of the first liquid outlet 4 on the automatic sealing assembly 3.

[0034] It should be noted that, as a preferred embodiment, referring to Figure 3 The rotating shaft 6 includes a central shaft 61 and an end shaft 62. U-shaped grooves are set at both ends of the central shaft 61. The end shaft 62 is a two-piece structure and is fixed to the top of the U-shaped groove. The two-piece end shaft 62 is merged under pressure. The shaft diameter of the two-piece end shaft 62 is larger than the shaft diameter of the central shaft 61, which can prevent the rotating shaft 6 from falling off. The operator merges the two-piece end shaft 62 by pressing the end shaft 62, reduces the shaft diameter of the two-piece end shaft 62, and facilitates the installation of the rotating shaft 6.

[0035] It should be noted that, as a preferred embodiment, a through hole 7 matching the diameter of the central axis 61 is provided on one end of the connecting rod 32 and the mounting portion 11, and the rotating shaft 6 is inserted into the above-mentioned through hole 7 to realize the rotational connection between the automatic sealing component 3 and the first liquid storage container 1. During installation, the two-piece end shaft 62 is merged under pressure. Since the aperture of the through hole 7 is larger than the diameter of the two-piece end shaft 62 after the pressure merger, the operator can insert the rotating shaft 6 into the through hole 7 by pressing the end shaft 62. After the rotating shaft 6 is inserted, the operator stops pressing the end shaft 62. Since the aperture of the through hole 7 is smaller than the diameter of the two-piece end shaft 62 in the non-pressure state, the rotating shaft 6 is fixed. Furthermore, the aperture of the through hole 7 is slightly larger than the diameter of the central axis 61 to prevent the rotating shaft 6 from shaking in the through hole 7.

[0036] It should be noted that, as a preferred embodiment, referring to Figure 3One end of the mounting portion 11 is connected to the first liquid storage container 1, and the other end of the mounting portion 11 is provided with a disassembly channel 11-1, which extends from the end face of the mounting portion 11 and is connected to the through hole 7 on the mounting portion 11. The connection position of the disassembly channel 11-1 and the through hole 7 on the mounting portion 11 constitutes two connection intersections, and the distance between the two connection intersections is greater than the axial diameter of the two-piece end shaft 62 after being combined under pressure. Furthermore, the opening of the disassembly channel 11-1 gradually increases from the through hole 7 on the mounting portion 11 to the bottom of the mounting portion 11, and the arc angle of the through hole 7 on the mounting portion 11 is greater than 160°. The disassembly channel 11-1 provides a mounting channel for the rotating shaft 6.

[0037] It should be noted that, as a preferred embodiment, referring to Figure 1 and 2 A bending portion 12 is provided on the top edge of the first liquid storage container 1, and one end of the bending portion 12 is provided to extend downward. The inner side wall of the bending portion 12 abuts against the outer side wall of the second liquid storage container 2. The bending portion 12 can hang the first liquid storage container 1 on the top of the second liquid storage container 2. Furthermore, multiple bending portions 12 can be provided along the top edge of the first liquid storage container 1, and the top of the second liquid storage container 2 can also be sealed.
