[0039] Combine the following Figures 1 to 6 , describing an embodiment of the utility model.

[0040] According to an embodiment of the present utility model, on the one hand, a container assembly is provided, comprising:

[0041] A container 1 having a cavity 12 therein suitable for containing liquid, and a first end surface of the container 1 having an opening 11;

[0042] The first end of the infusion tube 2 extends into the cavity 12 through the opening 11 and is located below the liquid level;

[0043] The first magnetic member 3 is fixedly connected to the first end of the infusion tube 2 . The first magnetic member 3 is suitable for being adsorbed and fixed on the inner wall of the container 1 to fix the relative position of the first end of the infusion tube 2 and the container 1 .

[0044] The container assembly provided in this embodiment is configured such that the first end of the infusion tube 2 extending into the cavity 12 is fixedly connected to the first magnetic component 3, so that the first end of the infusion tube 2 is fixed to the inner wall of the container 1 through the first magnetic component 3, thereby preventing the first end of the infusion tube 2 from moving relative to the container 1 under the action of the flow of liquid, or even causing the infusion tube 2 to be entangled.

[0045] Specifically, taking a liquid storage tank containing resin as an example, the container 1 is configured as a liquid storage tank, and the liquid is configured as resin. The first end surface of the container 1 can be the upper end surface of the container 1, or can be the side surface of the container 1. When the opening 11 is opened on the side surface of the container 1, the opening 11 is located in the upper area of ​​the side surface of the container 1. When it is necessary to fill the container 1 with liquid, it is suitable to fill the container 1 through the opening 11.

[0046] The infusion tube 2 is a flexible tube, and the first end of the infusion tube 2 extends below the liquid surface through the opening 11, and the second end of the infusion tube 2 is suitable for being connected to the liquid-using device, so that the liquid in the container 1 can be sucked into the liquid-using device through the infusion tube 2. In order to fix the first end of the infusion tube 2 below the liquid surface, preferably, the first magnetic member 3 is adsorbed and fixed on the bottom wall of the container 1, or adsorbed and fixed on the bottom area of ​​the side wall, so that the liquid inlet of the first end of the infusion tube 2 is located at the bottom of the liquid area, wherein the first magnetic member 3 includes an electromagnet or a magnet. Since the portion of the infusion tube 2 located in the container 1 has a certain length, when the liquid is stirred, it is easy to move relative to the container 1, or even entangled, so the first end of the infusion tube 2 is fixed to the inner wall of the container 1 through the first magnetic member 3 to avoid relative movement or entanglement with the container 1.

[0047] As a feasible implementation form, the bottom wall of the container 1 is made of metal material to be suitable for adsorption and fixation of the first magnetic member 3, or at least the bottom area of ​​the side wall of the container 1 is made of metal material to be suitable for adsorption and fixation of the first magnetic member 3. As an additional implementation form, the container 1 is made of non-metallic material, and a metal structure is fixedly connected to the bottom wall of the container 1, and / or a metal structure is fixedly connected to the bottom area of ​​the side wall of the container 1, wherein the metal structure is, for example, a metal plate, a metal rod, or a metal sphere, and the metal structure is fixedly connected to the inner wall and / or the outer wall of the container 1, and the first magnetic member 3 cooperates with the metal structure through magnetic attraction to fix the first end of the infusion tube 2 to the bottom of the container 1, thereby preventing the infusion tube 2 from moving relative to the container 1 or getting entangled.

[0048] In some embodiments, in combination Figures 1 to 6 As shown, the container assembly also includes a second magnetic component, which is fixedly connected to the bottom wall or side wall of the container 1 and is located below the liquid surface.

The magnetic cooperation between the second magnetic part and the first magnetic part 3 is conducive to improving operability.

[0050] Additionally, when the container 1 is made of non-metal, a second magnetic member may be fixedly connected to the bottom wall of the container 1, and / or a second magnetic member may be fixedly connected to the bottom area of ​​the side wall of the container 1, and the second magnetic member includes an electromagnet and a magnet, and is suitable for magnetically cooperating with the first magnetic member 3, so as to fix the first end of the infusion tube 2 to the bottom of the container 1. The second magnetic member is arranged on the inner wall and / or the outer wall of the container 1. Preferably, the second magnetic member is arranged on the outer wall of the container 1, so as to adjust the position of the second magnetic member on the container 1, thereby adjusting the first end of the infusion tube 2 to a suitable position, which is conducive to improving the operability of fixing the relative position of the first end of the infusion tube 2 and the container 1.

The first end of the stirring rod 4 is fixedly connected to a stirring head 5, and the stirring rod 4 is suitable for rotating around its own axis and driving the stirring head 5 to rotate to stir the liquid in the container 1.

[0052] The container assembly provided in this embodiment drives the stirring head 5 to rotate through the stirring rod 4, so as to stir the liquid in the container 1, thereby preventing the liquid from settling.

[0053] Specifically, taking the liquid storage tank that provides resin to the 3D printing device as an example, the precipitation of the resin in the liquid storage tank will affect the printing effect of the 3D printing device. Therefore, the stirring rod 4 drives the stirring head 5 to rotate, thereby stirring the resin inside the container 1, thereby preventing the resin from precipitating. As a feasible implementation form, the stirring head 5 includes at least one blade, and the plane where the blade is located is set at an angle to the horizontal direction, so as to stir the liquid in the container 1 when rotating around the axis of the stirring rod 4. As an additional, the stirring head 5 includes at least one straight plate or curved plate, and the plane where the straight plate or curved plate is located is set at an angle to the horizontal direction, so as to stir the liquid in the container 1 when rotating around the axis of the stirring rod 4.

[0058] Specifically, when the stirring head 5 is a flexible stirring head, when its size is larger than the size of the opening 11, it is inserted into the cavity 12 through the opening 11 in a bent state, so that the size specification of the stirring head 5 avoids the limitation of the size of the opening 11; when the stirring head 5 is a rigid stirring head, it is necessary to select a stirring head 5 of appropriate size according to the size of the opening 11.

[0059] In some embodiments, in combination Figures 1 to 6 As shown, the plane where the bottom wall of the container 1 is located is set at an angle to the horizontal direction, and the first end of the infusion tube 2 is located at the lowest point of the bottom wall of the container 1.

[0060] The container assembly provided in this embodiment is configured such that the plane where the bottom wall of the container 1 is located is angled with the horizontal direction, so that when the liquid in the container 1 is small, a small amount of liquid can be concentrated at the lowest point of the bottom wall; and the first end of the infusion tube 2 is configured at the lowest point of the bottom wall of the container 1, so that the infusion tube 2 can fully absorb the liquid in the container 1.
