The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring initially to fig. 1 and 2, an exemplary embodiment of a liquid storage container according to the present invention is shown. The liquid storage container comprises a liquid storage container body 1, wherein the liquid storage container body 1 is provided with an inner cavity for containing liquid, and an opening communicated with the inner cavity, and an external thread is formed on the peripheral wall of the opening.

The liquid storage container further comprises a cover structure, as shown in fig. 3 and 4, the cover structure comprises a cover main body 2, a gas passage 3 penetrating the cover main body 2, and a liquid passage 4 penetrating the cover main body 2.

The closure body 2 comprises an annular end wall 5, the annular end wall 5 forming an internal thread which cooperates with an external thread of the peripheral wall of the opening. When the internal thread of the annular end wall 5 is matched with the external thread of the peripheral wall of the opening, the opening of the liquid storage container main body 1 can be closed. Furthermore, a sealing ring 6 is arranged at the position where the opening is abutted against the cover main body 2 so as to improve the sealing performance of the opening and the cover main body. In alternative embodiments, the closure body and the reservoir body may also be snap-fit or otherwise removably connected.

The gas passage 3 includes a hose 7 that can be disposed in the internal chamber of the liquid storage container body 1. The closure further comprises a float 8, the float 8 forming a first gas passage to which the free end of the hose 7 is connected. The density of float 8 is less than the density of the liquid that the internal cavity holds, when the internal cavity holds liquid, no matter how the liquid storage container main part 1 is placed, float 8 all floats in liquid, of course, the length of hose 7 needs to guarantee that float 8 can float in liquid.

Specifically, the float 8 includes a float body 9 and a weight 10. The weight 10 has a density greater than the liquid contained in the internal chamber and urges the outer port 11 of the first gas passage to be above the liquid surface when the float 8 is floating on the liquid. Therefore, when the internal cavity contains liquid, no matter how the liquid storage container body 1 is placed, the external air port 11 of the first air channel is located above the liquid level, so that air inside and outside the internal cavity can flow through the first air channel and the air channel 3, and the situation that negative pressure or positive pressure is formed in the liquid storage container body 1 to affect liquid extraction and/or liquid backflow is avoided.

The first gas channel comprises a connecting pipe 12, one end of the connecting pipe 12 is sleeved with the hose 7, and the other end of the connecting pipe is inserted into the mounting hole of the floating piece main body 9. In this embodiment, the main body 9 of the floating member is a sphere, and the weight portion 10 is a ring shape and is sleeved on the connecting pipe 12 and disposed outside the main body 9 of the floating member. In alternative embodiments, the float body may also be generally ellipsoidal, cubic, shaped, etc., and the weight portion may also take other shapes, not to mention here.

The liquid channel 4 comprises a first liquid channel 13 capable of being arranged in the inner cavity of the liquid storage container body 1, a second liquid channel 14 capable of being arranged outside the inner cavity of the liquid storage container body 1, and a quick connector 15 fixed on the cover body 2 and used for connecting the first liquid channel 13 and the second liquid channel 14. The quick connector 15 comprises a quick connector male head 16 and a quick connector female head 17, wherein the connector end of the quick connector male head 16 is connected with the first liquid channel 13, and the connector end of the quick connector female head 17 is connected with the second liquid channel 14. The annular outer peripheral wall of the fixing portion 18 of the quick coupling male 16 forms an external thread, the cap body 2 forms an internal thread hole to be fitted with the external thread, and the stopper portion 19 of the quick coupling 15 male on the fixing portion 18 side abuts against the cap body 2.

In an alternative embodiment, the connector end of the female quick connector is connected to the first fluid passage and the connector end of the male quick connector is connected to the second fluid passage; the annular outer peripheral wall of the fixing part of the quick connector female head is provided with an external thread, and the sealing cover main body is provided with an internal thread hole matched with the external thread; the blocking part of the female head of the quick connector, which is positioned on one side of the fixing part, is abutted against the sealing cover main body.

Through the liquid passage 4, liquid can be supplied to the internal chamber of the liquid storage container body 1, and liquid contained in the internal chamber of the liquid storage container body 1 can also be extracted.

In this embodiment, the number of the liquid passages 4 is two, one liquid passage 4 is used for inputting liquid, such as backflow liquid, into the internal chamber of the liquid storage container body 1, and the other liquid passage 4 is used for extracting liquid contained in the internal chamber of the liquid storage container body 1. It should be understood that the number of the liquid channels 4 can be adjusted according to the actual use situation, such as one, three, four, etc.

The cover structure further includes a spring 20 sleeved on the second fluid passage 14 and having one end fixed to the joint of the quick coupling 15 and the second fluid passage 14. The spring 20 prevents the portion of the second fluid passage 14 near the junction of the quick connector 15 and the second fluid passage 14 from bending and affecting the flow of the fluid through the second fluid passage 14.

In this embodiment, a liquid filter 21 is provided at the end of the first liquid passage 13, and an air filter 22 is provided at the end of the gas passage 3 disposed outside the liquid storage container body 1. The annular outer peripheral wall of the fixing portion 23 of the air filter 22 forms an external thread, the cap body 2 forms an internal thread hole to be fitted with the external thread, and the stopper portion 24 of the air filter 22 on the fixing portion 23 side abuts against the cap body 2.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
