[0033] The present invention will be described more specifically by way of example in the following paragraphs with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0034] The following is in conjunction with the instruction manual appendix. Figures 1 to 3 This invention introduces a material container of the present invention.

[0035] In one embodiment, such as Figure 1 and Figure 2 As shown, the material tank includes a tank body 100 and an inlet pipe 200.

[0036] The inlet pipe 200 is used to introduce liquid materials into the tank 100, and the tank 100 is provided with an outlet 121 at the bottom.

[0037] The inlet pipe 200 includes a first pipe section 210 and a second pipe section 220. The first pipe section 210 extends outside the tank body 100, and the second pipe section 220 is located inside the tank body 100. The lower end of the second pipe section 220 is adjacent to the bottom of the tank body 100, and the lower end of the second pipe section 220 has a buffer section 221 for reducing the flow rate of liquid materials.

[0038] The lower end of the second pipe section 220 is adjacent to the bottom of the tank body 100, meaning that the two are relatively close. For example, there is a gap of 0.5-3 cm between the lower end of the second pipe section 220 and the bottom of the tank body 100.

[0039] This application, by positioning the lower end of the second pipe section 220 adjacent to the bottom of the tank 100 and configuring a flow velocity buffer section 221, allows the liquid material to directly enter the bottom of the tank 100, preventing direct impact on the liquid surface and splashing. This alters the flow path and energy transfer mode of the liquid material entering the container, allowing the fluid kinetic energy to be gradually absorbed by the bottom of the tank 100, reducing turbulence and bubble generation. Simultaneously, the deceleration effect of the buffer section 221, combined with the near-bottom injection method, significantly reduces the probability of eddy current formation within the liquid, resulting in smaller fluctuations in liquid pressure within the tank 100. This makes the liquid material more stable and less prone to disturbance, enabling the filling control system to stably control the liquid pressure, thereby improving filling accuracy.

[0040] In one embodiment, such as Figure 1As shown, the buffer portion 221 is a bent portion, the bent portion has a liquid outlet 121, the liquid outlet 121 is towards the side wall of the tank body 100, the liquid outlet 121 is adjacent to the side wall of the tank body 100 to make the liquid material contact the side wall of the tank body 100 when flowing out, so that the side wall of the tank body 100 can buffer the liquid material again, thereby further improving the stability of the liquid pressure in the material tank.

[0041] In one embodiment, the bent portion can be formed by bending the lower end of the liquid inlet pipe 200.

[0043] In other embodiments, the buffer portion can be in other forms, for example, a plurality of buffer baffles are arranged in the pipe end of the liquid inlet pipe, and a plurality of through holes are arranged on each baffle for the liquid material to pass through.

[0044] In one embodiment, in order to facilitate the arrangement of the liquid outlet 121, the tank body 100 comprises a main cavity section 110 and a liquid outlet cavity section 120 arranged in sequence from top to bottom, the cross-sectional area of the main cavity section 110 is greater than that of the liquid outlet cavity section 120, and the liquid outlet 121 is arranged at the bottom of the liquid outlet cavity section 120.

[0045] In one embodiment, in order to reduce the influence of the rapid drop of the liquid surface on the liquid pressure, the diameter of the main cavity section 110 is greater than or equal to 1.5 times the depth of the main cavity section 110, so that the main cavity section 110 of the tank body 100 is a flat structure, and the liquid surface in the main cavity section 110 drops slowly during the filling process, so that the liquid pressure at the bottom of the tank body 100 does not fluctuate obviously.

[0046] Preferably, the diameter of the main cavity section 110 can be 2 times the depth. In other embodiments, the diameter of the main cavity section 110 can also be 1.6 times, 2.2 times the depth.
