DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] In order to solve the technical problem of material hanging after dumping, the present utility model provides a storage tank that can avoid material hanging.

[0027] It should be noted that the storage tank described in the present utility model is used for but not limited to the storage of silicone, etc. For the convenience of description, in the present utility model, only a storage tank applied to a silicone storage device is taken as an example for description, and the principle of a storage tank applied to other types of devices is essentially the same as that applied to a silicone storage device, and will not be elaborated here one by one.

[0028] Please refer to Figure 1 - Figure 6 where Figure 1 is a schematic structural diagram of a storage tank in an embodiment of the present utility model. A storage tank includes a tank body 100, a top cover 200 and an anti-hanging funnel 300; the top cover 200 covers the top end of the tank body 100; the anti-hanging funnel 300 includes a funnel body 310, a return pipe 320 and a check valve 330. The funnel body 310 is detachably connected to the top cover 200. The bottom end of the return pipe 320 communicates with the upper part of the outer wall of the funnel body 310. The top end opening of the return pipe 320 is on the same side as the top end opening of the funnel body 310. The check valve 330 is inclined in the return pipe 320 to allow materials to flow into the tank body 100 unidirectionally.

[0029] In this embodiment, a basic anti-leakage structure is constructed by setting the funnel body 310; further, the return pipe 320 is provided and communicates with the upper part of the outer wall of the funnel body 310, so that when silicone leaks, it can flow along the outer wall of the funnel body 310 into the return pipe 320 in a timely manner and then flow back into the tank body 100, effectively avoiding material hanging.

[0030] In one of the embodiments, please refer to Figure 2 where a diversion surface 340 is provided between the funnel body 310 and the return pipe 320.

[0031] In this embodiment, the setting of the diversion surface 340 helps silicone to flow into the return pipe 320 orderly and prevents the overflow of silicone everywhere.

[0032] In one of the embodiments, please refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6, the top opening of the funnel body 310 is provided with a first chamfer 311, a notch 312 is formed at the first chamfer 311, and a second chamfer 313 is provided at the connection between the notch 312 and the diversion surface 340.

[0033] In this embodiment, the combined design of the first chamfer 311, the notch 312, and the second chamfer 313 helps the one-way and orderly pouring of silicone and makes the partially leaked silicone more concentratedly flow back to the return pipe 320 and the tank body 100 successively via the diversion surface 340, effectively improving the anti-hanging material ability.

[0034] In one embodiment, please refer to Figure 1 , the narrow end of the funnel body 310 is located on the side away from the top cover 200.

[0035] In this embodiment, the narrow end of the funnel body 310 being located on the side away from the top cover 200 helps to improve the guiding property and accuracy of pouring silicone by the funnel body 310.

[0036] In one embodiment, please refer to Figure 2 , the top opening of the return pipe 320 is semicircular.

[0037] In this embodiment, the top opening of the return pipe 320 being semicircular can receive materials such as the refluxed silicone to the greatest extent.

[0038] In one embodiment, please refer to Figure 2 , an observation window 350 is provided on the side wall of the return pipe 320.

[0039] In this embodiment, the observation window 350 enables the operator to observe the reflux situation at all times.

[0040] In one embodiment, please refer to Figure 3 , a partition 400 is provided in the tank body 100 and divides the inside of the tank body 100 into two parts.

[0041] In this embodiment, the setting of the partition 400 can facilitate the storage of different materials in the tank body 100 and improve the utilization rate.

[0042] In one embodiment, please refer to Figure 3 , a filter screen 500 is detachably connected in the tank body 100.

[0043] In this embodiment, the filter screen 500 helps to effectively filter out filter residues during storage.

[0044] In one embodiment, please refer to Figure 1 、 Figure 3 , the top cover 200 is threadedly connected to the tank body 100.

[0045] In one embodiment, please refer toFigure 1 , Figure 4 , a feed pipe 210 is provided at the top end of the top cover 200, and an unsealing cover 211 is provided on the feed pipe 210.

[0046] In this embodiment, the feed pipe 210 is provided with an unsealing cover 211, which is convenient for supplementing materials through the feed pipe 210.

[0047] To better understand the present utility model, the following will Figures 1 to 6 describe the technical solution of the present utility model in detail:

[0048] First, materials such as silicone are stored in the tank body 100; then, when taking, it is poured out normally through the top opening of the funnel body 310 and through one side of the notch 312; then, a small amount of materials such as silicone will leak to the outer wall of the funnel body 310; then, this part of the leaked silicone will gradually flow back into the return pipe 320 through the guiding surface 340 during the process of the tank body 100 returning to the horizontal state; then, this part of the silicone will continue to flow into the tank body 100 unidirectionally through the one-way valve 330; that is, the above structure can effectively prevent the problem of material hanging, reduce or even avoid waste. It should be emphasized that the bottom end of the return pipe 320 is connected to the upper part of the outer wall of the funnel body 310, greatly shortening the path of silicone leakage and the reflux efficiency, that is, the silicone can quickly flow back after leakage and the leakage amount is greatly reduced, that is, the anti-material-hanging ability is greatly improved.

[0049] The above specific implementation manners of the present utility model do not constitute a limitation to the protection scope of the present utility model. Any other corresponding changes and deformations made according to the technical concept of the present utility model shall be included in the protection scope of the claims of the present utility model.
