DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] The embodiment of the utility model provides a storage container 100 suitable for controlling the outflow of a solution under air pressure, and the storage container 100 includes: a barrel body 110, wherein a accommodating space is provided in the barrel body 110, and the barrel body 110 is provided with an opening 111, and the opening 111 is connected to the accommodating space; a cover body 120 covers the opening 111, and the cover body 120 is provided with a first through hole 121 and a second through hole 122; an air pressure pipeline 130, wherein one end of the air pressure pipeline 130 extends into the accommodating space through the first through hole 121; a liquid outlet pipeline 140, wherein one end of the liquid outlet pipeline 140 extends into the accommodating space through the second through hole 122; wherein the other end of the air pressure pipeline 130 is connected to an air pressure device, so that the air pressure device controls the solution to flow out through the liquid outlet pipeline 140.

[0038] For example, see the attached Figure 1 As shown, the storage container 100 includes: a barrel 110, a cover 120, an air pressure pipeline 130 and a liquid outlet pipeline 140. The barrel 110 is provided with a storage space for storing a solution. The opening 111 is connected to the storage space so that the experimenter can inject the solution into the storage space through the opening 111. The cover 120 covers the opening 111 to prevent dust or foreign matter from contaminating the solution. Figure 3 As shown, the cover body 120 is provided with a first through hole 121 and a second through hole 122. Figure 2 As shown, one end of the air pressure pipeline 130 extends into the containing space through the first through hole 121, and the other end of the air pressure pipeline 130 is connected to the air pressure device. The liquid outlet pipeline 140 extends into the containing space through the second through hole 122. When taking liquid, the air pressure device fills gas into the containing space through the air pressure pipeline 130. In order to maintain the pressure balance inside and outside the storage container 100, the solution in the containing space 100 flows out through the liquid outlet pipeline 140, thereby completing the liquid taking, which is convenient for the experimenter to operate. At the same time, in the process of taking liquid, there is no need to open the cover body 120, which reduces the contact between the solution and the external air and prevents the solution from being contaminated.

[0039] Preferably, a control valve is provided between the air pressure pipeline 130 and the air pressure device. When liquid needs to be taken, the control valve is opened to fill gas into the barrel body 110 to complete the liquid taking. When liquid is not taken, the control valve is closed to make the containing space a closed space to prevent external air from entering and contaminating the solution. Liquid is taken through the control valve, which is convenient for the experimenter to operate.

[0040] For example, the storage container 100 further includes a fixing member 160 , which is sleeved on the cover 120 to limit the movement of the cover 120 .

[0042] Specifically, the fixing member 160 includes an avoidance opening 161 . When the fixing member 160 is sleeved on the cover body 120 , the avoidance opening 161 is used to avoid the air pressure pipeline 130 and the liquid outlet pipeline 140 .

[0043] Specifically, as attached Figure 5 As shown, the fixing member 160 is provided with an avoidance hole 161. When the fixing member 160 is sleeved on the cover body 120, the avoidance opening 161 is used to avoid the air pressure pipeline 130 and the liquid outlet pipeline 140 to prevent position interference between the fixing member 160 and the two pipelines.

[0044] For example, the barrel body 110 further includes: a first boss 112, the first boss 112 is provided with a first abutment surface 112a; wherein the fixing member 160 is provided with a second abutment surface 162, when the fixing member 160 is sleeved on the cover body 120, the first abutment surface 112a and the second abutment surface 162 abut against each other.

When the fixing member is sleeved on the cover body, the first abutment surface 112a and the second abutment surface 162 abut against each other, which easily limits the movement of the fixing member 160, prevents the fixing member 160 from falling off, and increases the reliability of the fixing member 160.

[0046] Specifically, the fixing member 160 further includes: a third abutting surface 163 ; wherein the cover body 120 is provided with a fourth abutting surface 123 , and when the fixing member 160 is sleeved on the cover body 120 , the third abutting surface 163 and the fourth abutting surface 123 abut against each other.

[0047] Specifically, as attached Figure 6 As shown, the fixing member 160 is provided with a third abutting surface 163; Figure 3 As shown, the cover body 120 is provided with a fourth abutting surface 123 . When the fixing member 160 is sleeved on the cover body 120 , the third abutting surface 163 and the fourth abutting surface 123 abut against each other, thereby increasing the reliability of fixing the cover body 120 on the barrel body 110 .

[0048] For example, the fixing member 160 further includes an anti-slip portion 164 , which is disposed on the outer circumference of the fixing member 160 .

[0049] For example, see the attached Figure 5 As shown, the anti-slip portion 164 is disposed on the outer circumference of the fixing member 160 , wherein the anti-slip portion 164 is composed of a plurality of protrusions, which are arranged in sequence on the outer circumference of the fixing member 160 , thereby increasing the friction between the hand and the fixing member 160 .

[0050] Specifically, the storage container 100 further includes a sealing member 150 , which is disposed between the opening 111 and the cover 120 .

[0051] Specifically, the sealing member 150 is disposed between the opening 111 and the cover 120 . When the cover 120 covers the opening 111 , the sealing member 150 can play a sealing role to prevent external air from entering the containing space, thereby preventing the solution from deteriorating.

[0052] For example, the cover body 120 further includes: a groove 124 , which is disposed on a side of the cover body 120 close to the barrel body 110 , and at least a portion of the sealing member 150 is embedded in the groove 124 .

[0053] For example, see the attached Figure 4 As shown, the groove 124 is arranged on the side of the cover body 120 close to the barrel body 110; at least a part of the seal 150 is embedded in the groove 124, so that the seal 150 can be fixed on the cover body 120. The fixing method of the seal 150 is relatively simple, which is convenient for disassembly and replacement. At the same time, it can avoid the seal 150 from being offset, thereby ensuring the sealing effect.

[0054] Specifically, the barrel body 110 further includes a handle portion 113 , which is disposed outside the barrel body 110 .

[0055] Specifically, as attached Figure 1 As shown, a handle portion 113 is provided on the outside of the barrel body 110, and the handle portion 113 is arranged close to the cover body 120 to facilitate movement by experimenters.

[0056] For example, the barrel body 110 further includes: a second boss 114 , which is disposed outside the barrel body 110 ; wherein one end of the handle portion 113 is fixed to the barrel body 110 , and the other end of the handle portion 113 is fixedly connected to the second boss 114 .

[0057] For example, see the attached Figure 1 As shown, one end of the handle portion 113 is fixed on the barrel body 110, and the other end of the handle portion 113 is fixedly connected to the second boss 114, so that the handle portion 113 is fixed more reliably, and the handle portion 113 is arranged close to the opening 111, so that it is more convenient for the experimenter to move the storage container 100.
