Description

Technical Field

[0001] This utility model relates to the field of automatic spray paint can technology, specifically to the inner liner of an automatic spray paint can. Background Technology

[0002] Automatic paint sprayers are frequently used in spray painting operations. Because they are convenient and quick to operate, they are widely used. Therefore, we propose an inner liner for an automatic paint sprayer.

[0003] Chinese Patent No. CN203803740U discloses an automatic paint spraying can and its inner liner. The inner liner includes an inner liner body and an inner liner lid, both with outward-flared edges. A sealing seat is installed inside the inner liner lid, and a push rod is sealed through the sealing seat, with its outer end sealingly protruding from the inner liner lid. The inner liner body has a detachable part, and the inner end of the push rod contacts the detachable part. This invention, based on existing automatic paint spraying cans, opens at the bottom and seals an inner liner, with a sealed push rod protruding from the inner liner. Another component can be placed inside the inner liner. When needed, the push rod is pushed forcefully to open the detachable part of the inner liner, allowing the component inside to mix and react with the liquid in the main body of the paint spraying can. After vigorous shaking, a suitable paint for spraying is obtained for rapid application.

[0004] The existing technology has the following drawbacks: 1. In the current inner liner structure, the inner liner and outer can are stored separately before filling, making them prone to deformation due to compression. 2. The current inner liner structure has a relatively small capacity. 3. In the current inner liner structure, the main body of the ejector rod has a "cross-shaped blade" perimeter, which is complex to manufacture, easy to perforate, and difficult to eject. Therefore, we propose an inner liner for a self-spraying paint can to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide an inner liner for a spray paint can, which has the advantages of being less prone to deformation at the connection between the inner liner and the can body, increasing the capacity of the inner liner, and facilitating ejection, thereby solving the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an inner liner for a spray paint can, comprising an outer can body, an inner liner body integrally riveted to the bottom of the inner cavity of the outer can body, the inner liner body being flared in shape, the top diameter of the inner liner body decreasing, a convex piston being filled at the top of the inner liner body, a guide structure being embedded and fixedly connected to the bottom of the inner cavity of the inner liner body, a top rod being slidably connected to the inner cavity of the guide structure, a top block being integrally connected to the top of the top rod, the bottom of the top rod penetrating the inner liner body and extending to the bottom of the inner liner body, and a cap being threadedly connected to the bottom of the top rod.

[0007] To facilitate the filling of the inner liner, the inner liner of the self-spraying paint can of this utility model is preferably cylindrical, and both the top rod and the top block are hollow and connected.

[0008] To facilitate the vertical movement of the top rod, the inner liner of the spray paint can of this utility model preferably includes a cylindrical body. A sliding cylinder is embedded and fixedly connected to the top of the inner cavity of the cylindrical body. The inner surface of the sliding cylinder is slidably connected to the surface of the top rod. A spring is sleeved on the surface of the top rod, and the top and bottom ends of the spring are fixedly connected to the cylindrical body.

[0009] To improve the sealing performance of the inner liner bottle opening, as a preferred embodiment of the inner liner of this utility model, the surface of the convex piston is fitted with a sealing ring.

[0010] To facilitate observation of the material filling process, the inner liner of the self-spraying paint can of this utility model preferably has a paint spray head connected to the top of the outer can body, and an observation window is embedded and fixedly connected to the front of the outer can body at the initial position corresponding to the top block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] When this utility model is in use, the bottom of the outer canister's inner cavity is riveted to the inner liner, which improves the stability of the connection and avoids compression deformation when the two are placed separately.

[0013] Meanwhile, the inner liner is funnel-shaped, which increases its capacity;

[0014] The reduced diameter at the top of the inner liner allows the push rod to easily push open the convex piston without shifting. The guide structure design makes it more stable to push out, thus replacing the cross-shaped blade design.

[0015] Open the cap connected to the bottom of the top rod and invert the outer tank to facilitate filling materials during processing. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 A spray paint can inner liner includes an outer can body 1, an inner liner body 2 integrally riveted to the bottom of the inner cavity of the outer can body 1, the inner liner body 2 is flared, the diameter of the top of the inner liner body 2 is reduced, the top of the inner liner body 2 is filled with a convex piston 3, a guide structure 4 is embedded and fixedly connected to the bottom of the inner cavity of the inner liner body 2, a push rod 5 is slidably connected to the inner cavity of the guide structure 4, a top block 6 is integrally connected to the top of the push rod 5, the bottom of the push rod 5 penetrates the inner liner body 2 and extends to the bottom of the inner liner body 2, and a cap 7 is threadedly connected to the bottom of the push rod 5.

[0022] In this embodiment:

[0023] By riveting the bottom of the inner cavity of the outer tank 1 to the inner liner 2 as a whole, the stability of the connection is improved, and the situation of compression and deformation when placed separately is avoided.

[0024] Meanwhile, the inner liner 2 is funnel-shaped, which can increase the capacity of the inner liner 2;

[0025] The smaller diameter at the top of the inner liner 2 allows the push rod 5 to easily push open the convex piston 3 without shifting. The guide structure 4 makes it more stable to push out, thus replacing the cross-shaped blade design.

[0026] Open the cover 7, which is threaded at the bottom of the top rod 5, and simultaneously invert the outer tank 1 to facilitate filling with materials during processing.

[0027] As a further technical optimization of this utility model, the top rod 5 is cylindrical, and both the top rod 5 and the top block 6 are hollow structures and connected.

[0028] In this embodiment, by setting both the top rod 5 and the top block 6 to be hollow and connected, it is convenient to fill the inner liner 2 with the material.

[0029] As a further technical optimization of this utility model, the guide structure 4 includes a cylinder 41, a slide cylinder 42 is embedded and fixedly connected to the top of the inner cavity of the cylinder 41, the inner surface of the slide cylinder 42 is slidably connected to the surface of the top rod 5, and a spring 43 is sleeved on the surface of the top rod 5, with the top and bottom ends of the spring 43 being fixedly connected to the cylinder 41.

[0030] In this embodiment, the cylinder 41, the slide 42 and the spring 43 are provided to facilitate the up-and-down movement of the top rod 5.

[0031] As a further technical optimization of this utility model, a sealing ring is fitted on the surface of the convex piston 3.

[0032] In this embodiment: the sealing performance of the inner liner's two bottle openings is improved by setting a sealing ring.

[0033] As a further technical optimization of this utility model, the top of the outer tank 1 is connected to a paint spray head, and an observation window 8 is embedded and fixedly connected to the front of the outer tank 1 at the initial position corresponding to the top block 6.

[0034] In this embodiment: By setting an observation window 8, it is convenient to observe the filling process of the material.

[0035] The principle of this embodiment is as follows:

[0036] When in use, the inner liner can be directly processed and fixed in the outer can in the early stage, so that the bottom of the inner cavity of the outer can 1 and the inner liner 2 are riveted together to improve the stability of the connection and avoid the situation of compression and deformation when placed separately.

[0037] Open the cover 7, which is threaded to the bottom of the top rod 5, and simultaneously invert the outer tank 1. The required material can then be filled into the inner liner 2. The material enters through the top rod 5 and the top block 6. Then, close the cover 7 and observe the material volume through the observation window 8, ensuring that it does not exceed the highest position of the initial position of the top block 6.

[0038] Meanwhile, the inner liner 2 is funnel-shaped, which can increase the capacity of the inner liner 2;

[0039] The reduced diameter at the top of the inner liner 2 allows the push rod 5 to easily push open the convex piston 3 without shifting. When needed, simply press the push rod 5 to press the spring 43, and the convex piston 3 will be pushed out more stably through the guide of the slide cylinder 42, thus replacing the cross-shaped blade design.

[0040] By designing the above structure, the connection between the inner liner and the tank body is less prone to deformation, the inner liner capacity is increased, and it is easier to eject the contents.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
