Description

Technical Field

[0001] This utility model relates to a disposable multifunctional no-wash spray paint bottle, belonging to the technical field of spray paint bottles. Background Technology

[0002] A paint sprayer is a tool commonly used in the automotive repair and painting industry. It works with a spray gun to evenly spray paint onto a target surface, providing efficient, fast, and precise painting results.

[0003] Currently, paint sprayers on the market have limited functionality. After use or when changing paint colors, the equipment needs to be cleaned, significantly reducing work efficiency and wasting a large amount of paint cleaning solvent. Cleaning solvents, as chemical products, cause environmental pollution, requiring careful handling and proper post-treatment environmental remediation, all of which increase the cost of using spray painting equipment. Furthermore, existing paint sprayers are generally inverted, meaning the bottom of the sprayer faces upwards during use, with an air inlet at the bottom. When paint is sprayed, outside air automatically enters the sprayer through the air inlet. However, with existing sprayers, the air vent cannot be temporarily closed after being opened, rendering the contents unusable, especially after prolonged storage. Some sprayers with caps on the air vents mostly use a simple and quick cap-and-remove method, but the caps are easily lost during use, making it impossible to re-cap them.

[0004] Therefore, there is an urgent need in this field for a paint can that does not require cleaning, can be used multiple times, and thus effectively improves environmental pollution and reduces production costs. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a disposable multi-functional no-wash spray paint can with multiple functions, including color matching, spraying, quick replacement, and sealed storage.

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Reference Figure 1-Figure 5 A disposable multi-functional no-wash spray paint can includes a can body 1 and a can lid 2, which are detachably connected by threads. A vent 11 protruding from the bottom wall of the can body 1 is integrally formed. At least one vent hole 12 communicating with the inner cavity of the can body 1 is formed on the inner wall of the vent 11. A plug 3 for opening and closing the vent hole 12 is rotatably mounted on the vent 11. A limiting structure 4 restricting the rotation of the plug 3 is provided between the outer wall of the vent 11 and the plug 3. The placement of the vent hole 12 ensures the normal operation of the spraying process. Meanwhile, the opening and closing can be achieved by rotating the seal 3, and the seal 3 does not need to be removed, which is convenient, quick and not easy to lose. The remaining single-component paint in the spraying operation can be safely stored for the next workpiece spraying, avoiding waste. In this embodiment, the lid 2 and the body 1 include, but are not limited to, polyethylene or polypropylene structural parts, which are lightweight, not easy to break and low in cost. If there is no paint left after the spraying is completed, it can be directly discarded after the spraying is completed without cleaning, reducing workload and solvent usage, and effectively improving environmental pollution.

[0031] The inner wall of the vent 11 is integrally formed with a transition post 111. The sealing 3 is provided with a shaft hole 32 that is rotatably inserted into the transition post 111. The shaft hole 32 and the transition post 111 are preferably connected by a transition fit. The vent hole 12 is provided with multiple holes that are evenly spaced around the circumference of the transition post 111. The sealing 3 is provided with multiple vents 31 that are spaced around the circumference of the shaft hole 32 for communicating with the corresponding vent hole 12. In this embodiment, there are two vent holes 12 and two vents 31. The vents 31 are arranged in a fan shape.

[0032] Furthermore, the limiting structure 4 includes limiting ribs 41, locking posts 42, and limiting post feet 43. The limiting ribs 41 are evenly spaced around the circumference of the pivot shaft 111 on the outer wall of the vent 11. The number of limiting ribs 41 is twice that of the vent holes 12. The number of limiting post feet 43 is the same as the number of limiting ribs 41. Multiple limiting post feet 43 are evenly spaced around the circumference of the shaft hole 32 on the sealing 3. The limiting post feet 43 rotate with the sealing 3 and are positioned between two adjacent limiting ribs 41. The number of locking posts 42 is the same as that of the limiting ribs 41. The vent holes 12 are identical. Any two locking posts 42 are circumferentially distributed on the outer wall of the vent nozzle 11 on one side of the two opposing limiting ribs 41. The bottom wall of the limiting post foot 43 is slightly lower than the top wall of the locking post 42. The bottom side wall of the limiting post foot 43 and the top side wall of the locking post 42 are integrally formed with mutually abutting rounded corners. The limiting post foot 43 can be rotated and locked between the limiting ribs 41 and the locking post 42 by the sealing 3. When the limiting post foot 43 is locked between the limiting ribs 41 and the locking post 42, the vent hole 12 is closed.

[0033] Multiple rubber blocks 33 are also installed on the sealing 3 corresponding to the vent 12. When the limiting column foot 43 is locked between the limiting rib plate 41 and the locking column 42, the vent 12 is blocked by the rubber blocks 33, thereby improving the airtightness.

[0034] Furthermore, an annular protrusion 112 is integrally formed on the outer wall of the end of the vent 11 facing away from the body 1. The plug 3 is provided with an annular groove 34 that rotates with the annular protrusion 112. The wall thickness of the annular protrusion 112 is much smaller than the wall thickness of the vent 11, which can limit the rotation of the plug 3 to ensure the stability of the plug 3 when rotating. At the same time, when sufficient external force is applied, the plug 3 can be removed for easy replacement and maintenance.

[0035] Reference Figure 6 and Figure 7 The lid 2 has an integrally formed connector structure 5 for connecting various compatible adapters 7, which in turn connect to an external paint gun, enabling it to be used on various paint guns; the inner wall of the lid 2 has an integrally formed multiple limiting protrusions 21, and a filter screen 6 is detachably installed between the inner walls of the lid 2 through the multiple limiting protrusions 21, so that impurities in the paint can be filtered through the filter screen 6.

[0036] The connector structure 5 includes a first connecting part 51 and a second connecting part 52. Both the first connecting part 51 and the second connecting part 52 are annular and coaxially mounted on the lid 2. The outer diameter of the first connecting part 51 is smaller than the inner diameter of the second connecting part 52. The end face of the first connecting part 51 protrudes beyond the end face of the second connecting part 52. A threaded portion 511 is provided on the outer wall of the end of the first connecting part 51 that protrudes beyond the second connecting part 52. Multiple cylindrical spiral-shaped snap-fit ​​protrusions 521 are distributed circumferentially on the outer wall of the second connecting part 52. The adapter 7 has a threaded connection with the threaded portion 511. The adapter 7 has a threaded part 71 and multiple cylindrical spiral-shaped locking protrusions 72 that are adapted to engage with the locking protrusions. During installation and use, the locking protrusions 72 on the adapter 7 are inserted into the gap between the locking protrusions 521 on the second connecting part 52. This allows for quick positioning of the adapter and the connector structure 5. Then, by rotating the adapter 7, the locking protrusions 521 and 72 are locked in place. At the same time as the adapter 7 is rotated, the threaded part 511 and the threaded part 71 are simultaneously screwed together. This makes installation convenient, quick, and efficient.

[0037] Furthermore, multiple reinforcing ribs 53 are circumferentially distributed and integrally formed between the first connecting part 51 and the second connecting part 52 to improve the overall structural strength of the joint structure 5.

[0038] Reference Figure 1-Figure 3 The bottom wall of the spray bottle 1 is integrally formed with a ring of supporting legs 8. The vent 11 and the plug 3 are located within the range of the supporting legs 8, so that the spray bottle can be placed stably when not in use. Multiple opening slots 81 are distributed around the outer wall of the supporting legs 8 to facilitate the operator to pick up and remove the spray bottle.

[0039] The body of the pot 1 can also be marked with scales (not shown in the figure) as a basis for color mixing. This is existing technology and will not be described in detail.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit this utility model in any form or substance. It should be noted that those skilled in the art can make various improvements and additions without departing from this utility model, and these improvements and additions should also be considered within the protection scope of this utility model. Any modifications, alterations, and equivalent changes made by those skilled in the art without departing from the spirit and scope of this utility model using the disclosed technical content are equivalent embodiments of this utility model. Furthermore, any modifications, alterations, and evolutions made to the above embodiments based on the essential technology of this utility model are still within the scope of the technical solution of this utility model.
