[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] As Figures 1-6 shown, this embodiment provides a fluid memory, including:

[0033] A kettle body 1, the kettle body 1 has a kettle mouth 11, and a plurality of connecting parts 12 are further arranged on the kettle body 1. A horizontally arranged slot 13 is arranged on the connecting part 12, and an anti - detachment protrusion 14 is arranged in the slot 13. The anti - detachment protrusion 14, and a plurality of the connecting parts 12 are distributed around the kettle mouth 11;

[0034] An inner liner 3;

[0035] A kettle lid 2, a connecting pipe 21 is arranged on the kettle lid 2, and an annular pressing ring 22 is further arranged on the kettle lid 2. The extending direction of the connecting pipe 21 is arranged in a direction opposite to the extending direction of the annular pressing ring 22. A plurality of inserting tongues 23 are further arranged on the edge of the kettle lid 2, and a plurality of the inserting tongues 23 are arranged outside the annular pressing ring 22;

[0036] Wherein, the inner liner 3 is inserted into the kettle body 1 through the kettle mouth 11, the annular pressing ring 22 is inserted into the kettle mouth 11, and the inner liner 3 is sandwiched between the annular pressing ring 22 and the kettle body 1; the inserting tongues 23 are inserted into the corresponding slots 13, and the anti - detachment protrusion 14 is arranged outside the end of the inserting tongue 23 and is configured to prevent the inserting tongue 23 from detaching from the slot 13.

[0037] Specifically, in this embodiment, the fluid storage device uses the inner liner 3 to hold paint. The inner liner 3 is placed in the kettle body 1, and then, the kettle lid 2 covers the mouth of the inner liner 3, and the kettle lid 2 is connected to the kettle body 1. In order to meet the connection requirements between the kettle lid 2 and the kettle body 1, the kettle body 1 itself is provided with a plurality of connecting parts 12, and a horizontally arranged slot 13 is arranged on the connecting part 12. Correspondingly, a plurality of inserting tongues 23 are arranged on the edge of the kettle lid 2.

[0038] During the actual assembly process, after the inner liner 3 is placed into the kettle body 1, the position of the kettle lid 2 is adjusted so that the inserting tongues 23 of the kettle lid 2 can be adjacent to the slots 13 at the corresponding positions. Then, the kettle lid 2 is pressed on the kettle body 1 so that the annular pressing ring 22 is inserted into the mouth of the inner liner 3; at this time, the side wall of the inner liner 3 below the mouth of the inner liner 3 will be squeezed between the annular pressing ring 22 and the inner wall of the kettle body 1 to seal the mouth of the inner liner 3 through the kettle lid 2. Finally, rotate a certain angle so that the inserting tongues 23 are inserted into the slots 13 to realize the connection and fixation between the kettle lid 2 and the kettle body 1.

[0039] In this way, since the kettle lid 2 can be directly connected and fixed to the kettle body 1 through the cooperation of the insertion tongue 23 and the slot 13, there is no need to additionally increase a connecting ring, thus reducing the number of components to lower the manufacturing cost. Moreover, for the direct connection between the kettle lid 2 and the kettle body 1, during the process of inserting the insertion tongue 23 of the kettle lid 2 into the slot 13, the rotation angle of the kettle lid 2 is relatively small, and thus it will not affect the inner container 3 squeezed between the annular pressing ring 22 and the kettle body 1, ensuring the reliability of use of the inner container 3. More importantly, during use, after the insertion tongue 23 is inserted into the slot 13, the insertion tongue 23 will be limited by the anti - detachment protrusion 14 to prevent the insertion tongue 23 from disengaging from the slot 13 by itself, improving the overall reliability of use of the fluid storage device.

[0040] Further, one end of the slot 13 forms an open end, and the other end of the slot 13 forms a closed end, and the anti - detachment protrusion 14 is close to the open end of the slot 13;

[0041] The size of the slot 13 gradually decreases from the open end to the closed end direction.

[0042] Specifically, in order to improve the connection reliability between the insertion tongue 23 and the slot 13 and facilitate the operator to accurately insert the insertion tongue 23 into the slot 13, for the slot 13, it adopts a gradient structure. The size of the open end of the slot 13 is larger to facilitate the accurate insertion of the insertion tongue 23 into the slot 13. As the insertion tongue 23 continues to be inserted into the slot 13, the size of the slot 13 gradually becomes smaller, so that the insertion tongue 23 can closely adhere to the inner wall of the slot 13.

[0043] Further, the connecting portion 12 is a convex structure provided on the outer wall of the kettle body 1. The convex structure extends to the outside of the kettle mouth 11, and the slot 13 is formed on the inner wall of the convex structure.

[0044] Specifically, in order to form the slot 13 on the kettle body 1 to meet the installation requirements of the kettle lid 2, a convex structure can be formed on the outer wall of the kettle body 1. The convex structure protrudes from the outer wall of the shell and is higher than the kettle mouth 11 of the kettle body 1. The slot 13 is formed on the inner surface of the part of the convex structure that is higher than the kettle mouth 11.

[0045] The convex structure formed on the outer wall of the kettle body 1 as the connecting portion 12 can improve the structural strength of the connecting portion 12 itself to meet the requirement of reliable connection with the kettle lid 2.

[0046] Wherein, a hollow hole is further formed between the convex structure and the outer wall of the kettle body 1. Specifically, the design of the hollow hole can reduce the amount of material used, which is more conducive to reducing the manufacturing cost.

[0047] Furthermore, the head of the tongue 23 is provided with an inclined surface 231, and the inclined surface 231 is configured to guide the tongue 23 to slide over the anti - detachment protrusion 14 and insert into the slot 13.

[0048] Specifically, since the tongue 23 needs to pass over the anti - detachment protrusion 14 during the process of inserting the tongue 23 into the slot 13, in order to make the insertion process smoother, an inclined surface 231 matching the anti - detachment protrusion 14 is provided at the head position of the tongue 23. During the process of inserting the tongue 23 into the slot 13, the inclined surface 231 will first contact the anti - detachment protrusion 14, and under the guiding action of the inclined surface 231, the tongue 23 can slide over the anti - detachment protrusion 14 more smoothly and be inserted in place.

[0049] Furthermore, the mouth of the inner container 3 is provided with an outward - turned edge 31, the outward - turned edge 31 is lapped on the edge of the mouth 11 of the pot body 1, and the outward - turned edge 31 is also clamped between the pot body 1 and the pot lid 2.

[0050] Specifically, the mouth of the inner container 3 is provided with an outward - turned edge 31. After the pot lid 2 is connected to the pot body 1, the outward - turned edge 31 will be clamped between the edge of the pot lid 2 and the edge of the pot body 1 to improve the fixing reliability of the inner container 3.

[0051] Furthermore, a plurality of raised sealing ribs 221 are provided on the outer peripheral circle of the annular pressing ring 22, and the sealing ribs 221 abut against the inner wall of the inner container 3.

[0052] Specifically, in order to improve the sealing performance of the connection between the annular pressing ring 22 and the inner container 3, a plurality of annular sealing ribs 221 can be provided on the outer surface of the annular pressing ring 22. After the annular pressing ring 22 is inserted into the mouth of the inner container 3, the sealing ribs 221 can squeeze the inner wall of the inner container 3 to seal the mouth of the inner container 3.

[0053] Furthermore, the inner container 3 has a sealing part 32 and a liquid storage part 33, and the sealing part 32 is connected between the outward - turned edge 31 and the liquid storage part 33; the wall thickness of the sealing part 32 is greater than the wall thickness of the liquid storage part 33, and the sealing ribs 221 are abutted against the sealing part 32.

[0054] Specifically, the inner container 3 has an annular sealing portion 32 and a liquid storage portion 33 in a cup-like structure. An outward-turned edge 31 is provided on the sealing portion 32, and the sealing portion 32 needs to cooperate with the annular pressing ring 22 during the assembly process to achieve the sealing treatment. In order to improve the reliability of the connection of the inner container 3, the wall thickness of the sealing portion 32 is designed to be relatively thick so that the sealing portion 32 has higher structural strength. In this way, during the process of installing the kettle lid 2 onto the kettle body 1, on the one hand, the sealing rib 221 can exert sufficient pressure on the sealing portion 32 to meet the sealing requirements, and on the other hand, the sealing portion 32 has sufficient structural strength to meet the requirements of overcoming friction and avoiding breakage when the kettle lid 2 rotates.

[0055] Compared with the prior art, the advantages and positive effects of the present utility model are as follows: By providing a connecting portion on the kettle body, and configuring a slot on the connecting portion to meet the requirement of directly connecting and fixing the kettle lid to the kettle body. Correspondingly, a tongue is provided on the kettle lid. In this way, during use, after pressing the inner container and the kettle lid onto the kettle body, only by horizontally inserting the tongue into the slot, the kettle lid can be directly connected to the kettle body by rotating a relatively small angle. This can not only meet the requirement of fixedly installing the kettle lid on the kettle body, but also meet the requirement of a relatively small rotation angle of the kettle lid to reduce wrinkles or breakage on the inner wall of the inner container in the kettle body. More importantly, the inserted tongue is limited by the anti-detachment protrusion in the slot to prevent the kettle lid from falling off the kettle body during use, thereby improving the convenience of use of the fluid storage device and reducing the manufacturing cost.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
