Description

Technical Field

[0001] The present invention relates to automotive painting supplies, and particularly to a flow guiding cover for a paint mixing cup that also has a capping function. Background Art

[0002] When a painter sprays paint, it is necessary to pour paint, thinner, etc. into a rigid container in proportion for paint mixing. The paint mixing cups in the prior art are equipped with cup lids that only have a capping function. When mixing paint, the cup lid is opened, and the paint and thinner are poured into the paint mixing cup in proportion, and then the mixed paint is directly poured into a fluid supply device such as a gravity cup. During the process of pouring the paint into the fluid supply device, due to the large opening of the paint mixing cup, a large area of the cup wall and the opening of the paint mixing cup will be contaminated, and even the outer surface of the cup wall of the paint mixing cup will be stained with paint; after the paint mixing cup is used, when the cup lid is installed on the cup, due to the opening being contaminated with paint, the cup lid and the upper edge of the cup will stick together, increasing the difficulty of opening it next time; the opening of the paint mixing cup is generally large, and it is difficult to control the flow rate of the paint mixing cup, especially when the cup is full of paint, which will lead to a large error in the amount of paint poured into a fluid supply device such as a gravity cup; for another example, the volume of the paint mixing cup is larger than that of a fluid supply device such as a gravity cup, and it is necessary to pour into the fluid supply device multiple times. When there is still some paint left in the paint mixing cup and an incorrect operation occurs, when the cup body of the paint mixing cup is tilted, the paint will flow out instantaneously in a large area, causing pollution and waste; especially the caliber of a large-volume paint mixing cup is relatively large, while the caliber of a fluid supply device such as a gravity cup is generally small. When an operator directly pours paint, the flow rate is too large, and the gravity cup is often knocked down, resulting in waste of paint.

[0003] There has emerged a multifunctional paint mixing cup for automotive painting on the market, with a paint leakage port directly provided at the opening of the paint mixing cup, as Figure 1 shown, but it cannot be equipped with a corresponding cup lid, or even if a cup lid is equipped, it cannot achieve sealing. At the same time, the paint in the paint mixing cup cannot be poured out, and the cup lid needs to be repeatedly opened and closed to achieve the pouring of the paint. That is to say, in the prior art during specific operations, the paint mixing cup is in an open state for a long time, resulting in continuous volatilization of toxic substances (such as formaldehyde) in the paint, polluting the working environment.

[0004] Therefore, the prior art needs to be further improved and developed. Summary of the Invention

[0005] In view of the above deficiencies of the prior art, the purpose of the present invention is to provide a flow guiding cover for a paint mixing cup that also has a capping function, which can cap the paint mixing cup while allowing the user to more accurately control the flow rate of the poured paint.

[0006] To solve the above technical problems, the solution of the present invention includes:

[0007] A flow guide cover for a paint mixing cup that also has a capping function, which includes a lid body for capping the paint mixing cup. Among them, a strengthening part and a flow guide channel are provided on the lid body; a part of the flow guide channel is provided on the strengthening part, and the remaining part is provided on the lid body; a balance air hole is provided at the corresponding position of the lid body.

[0011] For the flow guide cover described above, among them, the strengthening part is at least one annular reinforcing rib. A part of the flow guide channel is provided on the outermost annular reinforcing rib, and the annular reinforcing rib is located in the middle of the lid body.

[0012] For the flow guide cover described above, among them, the outer contour of the flow guide channel is a part of a cylindrical or conical shape. The outlet of the flow guide channel is arranged obliquely from the outer edge of the lid body towards the strengthening part, and the end close to the outer edge of the lid body is higher than the end close to the strengthening part.

[0013] For the flow guide cover described above, among them, the outlet is oval.

[0014] For the flow guide cover described above, among them, a clamping and sealing structure adapted to the upper edge of the paint mixing cup is provided on the outer edge of the lid body, and there is a gap between the clamping and sealing structure and the flow guide channel.

[0015] For the flow guide cover described above, among them, the clamping and sealing structure includes a first annular plate arranged vertically along the outer edge of the lid body.

[0025] The present invention provides a flow guiding cover for a paint mixing cup with a capping function. To make the purpose, technical solution and effects of the present invention clearer and more definite, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] The present invention provides a diversion cover for a paint mixing cup that also has a capping function. As Figure 2 shown, it includes a lid body 1 for capping the paint mixing cup. The lid body 1 is provided with a reinforcing portion 2 and a diversion channel 3. A part of the diversion channel 3 is arranged on the reinforcing portion 2, and the remaining part is arranged on the lid body 1. A balance air hole 4 is arranged at the corresponding position of the lid body 1. And the diversion channel 3 and the balance air hole 4 can be respectively configured with a sealing plug 5. When in use, the sealing plug 5 is opened, and both the diversion channel 3 and the balance air hole 4 are in an open state. When the user tilts the paint mixing cup, the paint flows out from the diversion channel 3. The user can adjust the flow rate of the diversion channel 3 by adjusting the tilting angle of the paint mixing cup. And the diversion channel 3 only pollutes the environment at the outlet, greatly reducing the situation of large-area pollution at the cup mouth of the paint mixing cup in the prior art. And when not in use, the diversion channel 3 and the balance air hole 4 are blocked by the sealing plug 5. Even if the paint mixing cup is knocked over under the condition of misoperation, there will be no situation of large-area waste of paint.

[0027] To further describe the present invention, the above-mentioned reinforcing portion can be implemented in various ways such as a convex platform type reinforcing portion 2 (as Figure 2 shown), a concave platform type reinforcing portion 6 (as Figure 6 shown), or a reinforcing rib 7 (as Figure 7 shown), etc. Of course, it is not limited to the ways listed in this article, and other ways can also be adopted to implement the reinforcing portion.

[0028] As Figure 2 、 Figure 3 and Figure 4 shown, a circular hole 9 with a notch 8 is arranged in the middle of the above-mentioned lid body 1. A vertical wall 10 is arranged on the edge of the circular hole 9 except for the notch 8. A first lid body 11 is arranged on the vertical wall 10. The first lid body 11 is provided with an opening 12 at the position corresponding to the notch 8. The lid body 1 is provided with a hole 13 at the position corresponding to the notch 8. That is to say, the notch 8 is connected to the hole 13. The notch 8, the opening 12 and the hole 13 form a diversion hole 14. Exactly, the diversion hole 14 is formed by the notch 8, the opening 12, the hole 13 and the missing part of the vertical wall. The above-mentioned diversion channel 3 is arranged on the diversion hole 14. And the above-mentioned vertical wall 10 and the first lid body 11 are higher than the lid body 1, forming a convex platform type reinforcing portion. The opening 12 is located above the notch 8. That is to say, the part of the diversion channel 3 on the lid body 1 (also called the lower edge) is lower than the part on the reinforcing portion 2 (also called the upper edge). On the premise of having the above advantages, when the paint mixing cup is tilted, the paint will first contact the lower edge of the diversion channel 3, and the upper edge of the diversion channel 3 discharges a small amount of air during tilting, forming a buffer, further improving the smoothness of the paint flow. And the paint stained on the inner surface of the first lid body 11 will flow into the diversion channel 3 along the opening 12, avoiding the remaining paint stained on the inner surface of the first lid body 11 after pouring the paint.

[0029] More preferably, the outer contour of the above-mentioned diversion channel 3 is a part of a cylindrical or conical shape, and most preferably a part of a conical shape. As shown in Figure 3 , Figure 4 , the outlet 17 of the diversion channel 3 is arranged obliquely from the outer edge of the lid body 1 towards the reinforcing part 2. One end 15 close to the outer edge of the lid body 1 is higher than one end 16 close to the reinforcing part 2, and the outlet 17 is oval. After the paint pouring is completed and the paint mixing cup returns to the vertical state, since the opening 12 is located above and behind the hole 13, at this time, the opening 12 will first let in some air. The higher end 15 blocks the outflow of the paint, and the lower end 16, under the action of the gravity of the paint itself and in cooperation with the opening 12, more smoothly blocks the outflow of the paint, and ensures that the paint will not overflow when the flow is cut off, making the flow cut-off more stable.

[0030] In order to further ensure that the diversion lid does not deform during demolding and maintains its strength, the lid body 1 is in a circular shape, and the reinforcing part is also in a circular shape, that is, the center of the lid body 1 and the center of the first lid body 11 are on the same straight line. The diameter of the first lid body 11 is 1 / 3 - 2 / 3 of the diameter of the lid body 1, which can ensure that the diversion lid does not deform during demolding and also ensures the use strength of the diversion lid.

[0031] And a clamping and sealing structure 18 adapted to the upper edge of the paint mixing cup is provided on the outer edge of the above-mentioned lid body 1. There is a gap between the clamping and sealing structure 18 and the diversion channel 3, which can ensure the strength of the diversion channel 3 and also ensure that the clamping and sealing structure 18 and the diversion channel 3 will not shrink during injection molding and demolding.

[0032] And the convex reinforcing part 2 is higher than the lid body 1, and the outlet 17 is inclined towards the convex reinforcing part 2. Therefore, when a sealing plug 5 is inserted into the diversion channel 3, if the force is too large, the diversion channel 3 will bend and release force towards the convex reinforcing part 2, avoiding the situation of the paint mixing cup tipping over due to excessive force. Moreover, the height of the higher end 15 will be higher than the height of the clamping and sealing structure 18, so as to ensure that the paint can flow out smoothly and will not remain on the outer surface of the lid body 1, thereby reducing the pollution area during the paint pouring process of the paint mixing bucket. And both the diversion channel 3 and the convex reinforcing part 2 protrude upwards in the same direction, so that positioning is carried out through the diversion channel 3, and the adjacent upper and lower convex reinforcing parts 2 are just buckled together. Furthermore, during the transportation of the diversion lid, positioning can be carried out through the diversion channel 3, so that multiple diversion lids can be stacked on top of each other, saving transportation space.

[0033] In another preferred embodiment, as shown in Figure 6As shown, the above-mentioned vertical wall 10 and the first cover body 11 are lower than the cover body 1, forming a concave table-shaped reinforcing part 18, and the opening 12 is located below the notch 8. Its general situation is roughly the same as that of the above-mentioned preferred embodiment and will not be elaborated here. The difference is that since the concave table-shaped reinforcing part 18 is sunken and will occupy the volume of the paint mixing cup when the flow guiding cover is buckled on the paint mixing cup, the height of the concave table-shaped reinforcing part 18 needs to be more precisely controlled.

[0034] In another preferred embodiment, the above-mentioned reinforcing part is at least one annular reinforcing rib 19, as Figure 7 shown, it is composed of two annular reinforcing ribs 19, and a part of the flow guiding channel 3 is arranged on the outermost annular reinforcing rib 19, and the annular reinforcing rib 19 is located in the middle of the cover body 1. Its general situation is roughly the same as that of the above-mentioned preferred embodiment and will not be elaborated here. The difference is that in the way of using the annular reinforcing rib 19, due to different wall thicknesses, there is a situation of shrinkage between the annular reinforcing rib 19 and the cover body 11, which in turn leads to the probability of deformation of the flow guiding cover.

[0035] Furthermore, the clamping and sealing structure 18 can adopt the technical means known in the prior art and needs to match the upper edge of the paint mixing cup, and can be adjusted accordingly according to the structure of the paint mixing cup. Only one example is given here for illustration, but it should not be limited only to the examples given in this article. As Figure 5 shown, the above-mentioned clamping and sealing structure 18 includes a first annular plate 20 vertically arranged along the outer edge of the cover body 1. A second annular plate 21 arranged horizontally is provided on the upper edge of the first annular plate 20. A third annular plate 23 arranged vertically is provided on the outer edge of the second annular plate 21. The length of the third annular plate 23 is greater than that of the first annular plate 20. An accommodating space 24 adapted to the upper edge of the paint mixing cup is formed between the first annular plate 20 and the third annular plate 23, and the inner surface of the first annular plate 20 is adapted to the inner surface of the upper edge of the paint mixing cup; an annular convex rib 25 is provided on the third annular plate 23, and the annular convex rib 25 is adapted to the flanging of the upper edge of the paint mixing cup. Furthermore, the flow guiding cover and the paint mixing cup are locked through the accommodating space 24 and the annular convex rib 25, and surface sealing is carried out through the inner surface of the first annular plate 20 and the inner surface of the upper edge of the paint mixing cup.

[0036] In another preferred embodiment, the above-mentioned flow guiding cover is integrally formed by injection molding, which reduces costs and improves processing accuracy while. Of course, other processes can also be used. The lid body 1 and the first lid body 11 are both circular. Of course, the balance air holes 4 are generally arranged on the lid body 1, and the closer to the first annular plate 20, the better. However, there is a gap between the side wall of the balance air hole 4 and the outer surface of the first annular plate 20, which avoids shrinkage during the injection molding process. Moreover, the flow guiding channel 3 and the balance air hole 4 are located on the same diameter of the lid body. This is the optimal way. No matter how the lid body 1 rotates, the distance between the flow guiding channel 3 and the balance air hole 4 is always in the farthest state. Especially when the convex platform type strengthening part is adopted, even if the paint in the paint mixing cup is full, the paint will not pour out from the balance air hole 4 when pouring the paint, thereby improving the stability of use.

[0037] Of course, the above description is only a preferred embodiment of the present invention. The present invention is not limited to listing the above embodiments. It should be noted that all equivalent substitutions and obvious deformation forms made by any person skilled in the art under the teaching of this specification fall within the substantial scope of this specification and should be protected by the present invention.
