[0029] Example 1

[0030] Reference below Figure 1 and Figure 220. The liquid-filling apparatus of claim 19, wherein the lid 3 is connected to and fixed to the first container 1 and the second container 2, and the lid 3 fills the gap between the first container 1 and the second container 2, fixes the first container 1 and the second container 2, and seals the connection position between the first container 1 and the second container 2. A first liquid outlet 5 is provided at the bottom of the first container 1, and a second liquid outlet is provided at the bottom of the second container 2. A ventilation pipe 6 is further provided inside the first container 1, and the ventilation pipe 6 extends downward from the inner cavity of the first container 1 to the inner cavity of the second container 2. Openings are provided at both ends of the ventilation pipe 6 to connect the interiors of the first container 1 and the second container 2. In this embodiment, the first container 1 is provided on the upper part of the second container 2, and the first container 1 has liquid to be replenished, wherein the liquid level of the liquid to be replenished is lower than the opening height of the top of the ventilation pipe 6 in the first container 1, and the second container 2 has liquid to be discharged. When the first lid 3 closes the first container 1 and When the second container 2 is sealed, the second container 2 and the first container 1 are only connected by the ventilation pipe 6 to achieve gas communication. When the first liquid outlet 5 discharges liquid, the ventilation pipe 6 serves as a tool for balancing the air pressure inside the liquid adding device. The first container 1 discharges liquid from the first liquid outlet 5 to the second container 2, and the ventilation pipe 6 is ventilated. When the liquid in the second container 2 reaches the lower end opening of the ventilation pipe 6 and submerges the lower end opening, the ventilation pipe 6 cannot achieve gas communication. Due to the balance of air pressure in the first container 1 and the second container 2, the first liquid outlet 5 stops discharging liquid; when the liquid in the second container 2 is discharged from the second liquid outlet, the ventilation pipe 6 is ventilated, and the first liquid outlet 5 starts to replenish liquid. At this time, the connection between the first container 1 and the second container 2 is sealed, and the air pressure exchange between the first container 1 and the second container 2 is only achieved through the ventilation pipe 6. It should be noted that the automatic heating device provided in this embodiment only needs to open a first liquid outlet 1 and a ventilation pipe 6 connecting the interior between the first container 1 and the second container 2 to realize the automatic replenishment process. It has a simple structure and is easy to clean.

[0031] In one embodiment, referring to Figure 1 One end of the ventilation pipe 6 extends to the upper end of the first container 1, and there is a gap between the ventilation pipe 6 and the first cover body 3. The end point of the ventilation pipe 6 is higher, which prevents the liquid in the first container 1 from entering the ventilation pipe 6, and also allows the first container 1 to accommodate more liquid.

[0032] In one embodiment, the first liquid outlet 5 and the ventilation pipe 6 are arranged on both sides of the first container 1. The distance between the first liquid outlet 5 and the ventilation pipe 6 is relatively far. Figure 1The outer wall of the ventilation pipe 6 is connected to the inner wall of one side of the first container 1, and the first liquid outlet 5 is arranged on the side of the bottom of the first container 1 away from the ventilation pipe 6. The ventilation pipe 6 is installed on the leftmost side of the first container 1, and the first liquid outlet 5 is arranged on the right side of the first container 6. The ventilation pipe 6 is far away from the first liquid outlet 5 to avoid the liquid level shaking caused by the liquid discharge from affecting the ventilation of the ventilation pipe 6. As a preferred embodiment, the distance between the lower end face of the first liquid outlet 5 and the bottom face of the second container 2 is smaller than the distance between the lower end face of the ventilation pipe 6 and the bottom face of the second container 2, that is, the ventilation pipe 6 is higher than the first liquid outlet 5, which can further avoid the shaking of the liquid discharge from affecting the ventilation of the ventilation pipe 6.

[0033] In one embodiment, the first cover body 3 includes at least two parts: a cover body 31 and an extension part 32. The bottom of the cover body 31 is provided with a groove that matches the upper top surface of the first container 1 and the second container 2. The cover body 31 covers the top surface of the first container 1 and the second container 2. There is a gap between the first container 1 and the second container 2. The cover body 31 covers the annular gap formed between the first container 1 and the second container 2 to achieve a sealing effect.

[0034] In one embodiment, the first cover body 3 also includes an extension portion 32, which is arranged at the bottom of the cover body 31 and extends into the gap between the first container 1 and the second container 2. The extension portion 32 and the side wall of the first container 1 are provided with mutually matching threaded structures. In this embodiment, the inner side wall of the extension portion 32 is provided with a thread, and the outer side wall of the top of the first container 1 is provided with a thread matching the extension portion 32. The first container 1 and the first cover body 3 are connected and fixed by threads to achieve positioning between the first cover body 3, the first container 1 and the second container 2.

[0035] In one embodiment, the cover body 31 not only covers the gap between the first container 1 and the second container 2, but also covers the upper end surface of the first container 1. In addition, an opening is provided on the portion of the cover body 31 covering the upper end surface of the first container 1 to seal the first container 1 to prevent external contamination, and the first container 1 can be replenished with liquid through the opening.

[0036] In one embodiment, the automatic liquid replenishing device also includes a second cover body 4, which covers the opening on the cover body 31 and seals the opening. The second cover body 4 completely covers the opening. The second cover body 4 is made of elastic material and can produce a certain deformation. Since the first cover body 3 has more sealing structures, if it is necessary to add liquid to the first container 1, the first cover body 3 is inconvenient to disassemble and assemble, so the second cover body 4 is convenient for adding liquid to the first container 1; it should be noted that the second cover body 4 can be set with a smooth elastic material with a certain curvature, directly covering the opening position on the cover body 31. When the air pressure in the first container 1 changes, the second cover body 4 deforms downward, the seal is tighter, and air leakage is avoided to ensure the sealing effect.

[0037] In one embodiment, a seal is provided at the bottom of the second cover body 4, and the radial distance of the seal is the same as the inner diameter distance of the opening on the cover body 31. The thickness of the seal is less than the thickness of the cover body 31. The thickness of the seal is: the distance between the upper and lower top surfaces of the seal in the vertical direction, and the thickness of the cover body 31 is: the distance between the upper and lower top surfaces of the cover body 31 in the vertical direction. The thickness of the seal is less than the thickness of the cover body 31, which can further ensure the sealing effect.

[0038] In one embodiment, a support portion 21 is provided at the top end of the outer wall of the second container 2, and the support portion 21 extends along the four sides of the second container 2 in a direction away from the center of the second container 2, and the cover body 31 is provided on the support portion 21. During application, in order to ensure the sealing effect, the coverage area of ​​the cover body 31 needs to be larger than the top of the second container 2, and the support portion 21 is extended around the four sides of the second container 2. Furthermore, the support portion 21 includes a horizontal plate and a protrusion block, and the horizontal plate extends along the four sides of the second container 2 in a direction away from the center of the second container 2. The protrusion block is provided above the horizontal plate, and the protrusion block extends into the groove at the bottom of the first container 1. The horizontal plate and the protrusion block are used to support the first cover body 3 to improve the sealing effect.

[0039] Note that the above are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention. Therefore, while the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the scope of the present invention. The scope of the present invention is determined by the appended claims.
