Description

Technical Field

[0001] The utility model relates to the technical field of painting tools, in particular to a painting structure. Background Art

[0002] At present, liquid paint is usually applied by traditional means: a brush is dipped into the paint liquid in a container such as a bottle or a bucket. This method has many disadvantages: since the brush and the liquid container are separated, the painting efficiency is low, and the brush is dipped in the liquid and applied, and the liquid will inevitably splash or flow, which not only pollutes the environment but also causes waste. Therefore, a structure in which the brush and the liquid container are designed as one body has emerged.

[0003] If the existing coating structure adopts pressing, rotating, or ball-type, it is only suitable for small-point area operations, which not only causes repetitive movements but also has low efficiency; if a flat-head or sponge type is adopted, it is only suitable for flat surfaces, and the discharge amount cannot be controlled; if a brush head type is adopted, the discharge port is at the bottom of the bristles, and the operation of brushing is at the top of the bristles. Penetration from the bottom to the top will cause material waste, and the discharge amount cannot be controlled, and a large amount of residue will be left after use. Volatile materials will cause blockage at the bottle mouth after use.

[0004] For example, a Chinese patent with the announcement number CN2498904Y discloses a brush, including a handle and bristles, wherein a cavity is provided in the handle, a piston, a piston rod, a handle and a rear cover are arranged at the rear end of the handle, and a row of small through tubes are arranged in the bristles, and the small through tubes are communicated with the cavity of the handle;

[0005] The outlet end of the small through tube is located at the rear of the bristles, so that the brushing liquid needs to soak the entire bristles. In actual use, only the brushing liquid at the head of the bristles can play a brushing role, which is a serious waste. When using volatile liquids, the outlet end and the bristle head are easily blocked.

[0006] For example, a Chinese patent with the announcement number CN211211859U discloses a self-priming brush, including a brush body, a cavity is opened inside the brush body, and a piston that can move up and down is arranged inside the cavity; a plurality of bristles and a plurality of hoses are connected to the bottom of the brush body; one end of the hose is connected to the cavity; and the outlet end of the hose is flush with the edge of the bristles;

[0007] Most of the painting liquid delivered from the hose is directly applied to the parts to be painted, and less adheres to the bristles. It is easy for the squeezed painting liquid to fall out directly, and the amount is large and cannot be accurately controlled. Utility Model Content

[0008] The purpose of the utility model is to provide a painting structure to solve the problems raised in the above background technology.

[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] A coating brush structure comprises a material storage bottle, a bottle cap, a brush body and a material guide tube, wherein the bottle cap is detachably connected to a liquid outlet of the material storage bottle, and the brush body is arranged on the outside of the bottle cap and wraps the material guide tube inside;

[0011] The outer side of the bottle cap is provided with a support cover located around the outer periphery of the brush body;

[0012] The material guide pipe includes a hard material guide pipe and a soft material guide pipe;

[0013] The hard material guide tube passes through the bottle cap, the inner end of the hard material guide tube extends to the inside of the bottle cap to communicate with the inside of the storage bottle, the outer side wall of the hard material guide tube located inside the bottle cap is provided with a sealing gasket, and the outer end of the hard material guide tube extends to the inside of the brush body and is flush with the lower edge of the support cover;

[0014] One end of the soft material guiding tube is connected to the hard material guiding tube, and the other end extends to the lower edge of the brush body with a spacing.

[0015] Preferably, the liquid outlet of the storage bottle is provided with an external threaded port, and the bottle cap is provided with an internal threaded port threadably matched with the external threaded port.

[0016] Preferably, the cross-section of the brush body is circular, elliptical, triangular, square or rectangular.

[0017] Preferably, the cross-section of the inner cavity of the hard material guiding tube and the soft material guiding tube is circular, elliptical, triangular, square, rectangular or polygonal.

[0018] Preferably, the brush body is a soft-bristle brush or a hard-bristle brush that is densely arranged and fixed on the bottom wall of the bottle cap.

[0019] Preferably, the lower edge of the brush body is pointed, flat or arc-shaped.

[0020] Preferably, the distance between the soft material guiding tube and the lower edge of the brush body is set to a, the length of the soft material guiding tube not wrapped by the support cover is set to b, and the ratio of a to b is 1 / 2-4 / 3.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] The utility model extends the liquid outlet end of the soft material guide tube to the inside of the brush body and leaves a distance between the liquid outlet end and the lower edge of the brush body, so that the brushing liquid squeezed out of the storage bottle adheres to the head of the brush body, which can prevent the brushing liquid from being squeezed out and fall directly, and can also allow the brushing liquid to directly soak the head of the brush body to avoid waste.

[0023] Since the distance between the liquid outlet end of the soft material guiding tube and the lower edge of the brush body is relatively short, the squeezed liquid can flow back into the material storage bottle.

[0024] The soft material guide tube is deformable, which is beneficial to the application action of the brush body. The support cover shapes the upper part of the brush body to prevent the brush body from deforming too much. The hard material guide tube supports and shapes the soft material guide tube to maintain its relative position in the brush body.

[0025] Since the diameter of the soft material guide tube is larger than that of the hard material guide tube, a buffer storage space is formed and the center space at the lower edge of the brush body also forms a semi-open space. When the brushing stops, the storage bottle rebounds and the air pressure acts, and the semi-open space of the brush body and the guide tube form a channel to allow the remaining paint to flow back to the storage bottle;

[0026] The flexible guide tube can be deformed and bent, which is helpful for brushing on various surfaces such as uneven gaps and corners. When brushing, the brush body is pressed to squeeze the flexible guide tube, and the paint in the flexible guide tube is forced to flow to the brush body. The weight and frequency of the force on the brush body determine the amount of liquid output.

[0027] The support cover shapes the upper part of the brush body to prevent deformation of the brush body, while maintaining the stability of the brush body and preventing it from swaying. It supports and shapes the hard material guide tube and the soft material guide tube, while maintaining the relative position of the liquid outlet of the soft material guide tube in the brush body.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Example

[0038] A brushing structure, such as Figure 1-5 As shown, it includes a storage bottle 1, a bottle cap 2, a support cap 3, a brush body 4 and a material guiding tube.

[0039] The appearance of the storage bottle 1 can be in various forms. The storage bottle 1 can be a soft bottle with the interior used to store the painting liquid. The storage bottle 1 has high resilience. The outlet end of the storage bottle 1 is provided with an external threaded port 11.

[0040] The bottle cap 2 is provided with an internal threaded port 21, and the storage bottle 1 and the bottle cap 2 are connected or separated by threaded connection between the external threaded port 11 and the internal threaded port 21. The support cap 3 is fixed / sleeved on the outer bottom wall of the bottle cap 2.

[0041] The material guide tube includes a hard material guide tube 5, a soft material guide tube 6 and a sealing gasket 51 arranged on the outer wall of the hard material guide tube 5. The sealing gasket 51 can be made of rubber with a certain elastic force, or the hard material guide tube 5 and the sealing gasket 51 are connected as a whole and made of semi-hard plastic material; the outer contour of the sealing gasket 51 is adapted to the inner contour of the internal threaded port 21; during installation, the lower end of the hard material guide tube 5 is first passed through from the inside of the bottle cap 2 to the outside of the bottle cap 2, so that the sealing gasket 51 abuts against the inner bottom wall of the internal threaded port 21 in the bottle cap 2, and then the upper end of the soft material guide tube 6 is sleeved / bonded to the lower end of the hard material guide tube 5, and the caliber of the soft material guide tube 6 is larger than that of the hard material guide tube 5; then, when the external threaded port 11 and the internal threaded port 21 are threadedly connected, the sealing gasket 51 is used to improve the sealing performance to prevent the brushing liquid from overflowing. When the storage bottle 1 and the bottle cap 2 are connected as a whole, a small part of the upper end of the hard material guide tube 5 is relatively inserted into the storage bottle 1.

[0042] The brush body 4 can be made of soft / hard brushes densely arranged and fixed on the bottom wall of the bottle cap 2. The brush body 4 surrounds the outside of the hard material guide tube 5 and the soft material guide tube 6, so that the hard material guide tube 5 and the soft material guide tube 6 are relatively placed inside the brush body 4. The distance between the lower edge of the soft material guide tube 6 and the lower edge of the brush body 4 is assumed to be a, the length of the soft material guide tube 6 not wrapped by the support cover 3 (not covered on the hard material guide tube 5) is b, the ratio of a to b is 1 / 2-4 / 3, the distance between the bottom wall of the bottle cap 2 and the lower edge of the hard material guide tube 5 is c, and c is greater than b.

[0043] Then, a support cover 3 is sleeved / bonded / fixed on the bottom wall of the bottle cap 2. The lower edge of the support cover 3 is flush with the lower edge of the hard material guide tube 5. The support cover 3 relatively wraps the upper part of the brush body 4 to provide support. The support cover 3 supports the upper part of the brush body 4 to prevent deformation, and can also improve the stability of the brush body 4 during operation.

[0044] The cross section of the brush body 4 is in various shapes such as circular, elliptical, triangular, square, rectangular, etc.

[0045] The cross-section of the inner cavity of the hard material guiding tube 5 and the soft material guiding tube 6 is in various shapes such as circular, elliptical, triangular, square, rectangular, polygonal, etc.

[0046] The hard material guide tube 5 and the soft material guide tube 6 cooperate to form a material guide tube with both hard and soft properties. If only the hard material guide tube 5 is used, it cannot follow the deformation of the brush body 4; if only the soft material guide tube 6 is used, it is easy to deform at will and cannot return to normal in time, and it is impossible to ensure that the distance and position between the liquid outlet of the soft material guide tube 6 and the lower edge of the brush body 4 are within the set range.

[0047] The cover is also included, and when the brush structure is not in use, the cover is put on the bottle cap 2 / support cover 3, and the brush body 4 is completely covered by the cover for protection and sealing, so that the remaining powder material on the brush body 4 is kept dry, and the volatile liquid can be kept wet to prevent the bristles in the brush body 4 from drying and hardening. The material stored in the storage bottle 1 can be liquid or powder.

[0048] Working principle:

[0049] By squeezing the storage bottle 1, the brushing liquid in it is transported to the head of the brush body 4 (between the lower edge of the soft guide tube 6 and the lower edge of the brush body 4) through the hard guide tube 5 and the soft guide tube 6 in turn, and then the brushing action can be performed to transfer the liquid attached to the head of the brush body 4 to the part to be brushed. After the head of the brush body 4 absorbs the brushing liquid, it can achieve balanced discharge, no leakage and no drying during brushing; it can be quickly completed without residue on corner holes, large and small gaps, and surfaces of soft and hard materials. When it stops being used, the bottle body of the storage bottle 1 rebounds after the pressure disappears, and the brushing liquid in the soft guide tube 6 and the head of the brush body 4 flows back into the storage bottle 1, which not only improves work efficiency but also reduces the cost of materials used.

[0050] Since the coating liquid is mostly collected in the central area of ​​the hard guide tube 5, the soft guide tube 6 and the head of the brush body 4, when the squeezing stops, the bottle body of the storage bottle 1 rebounds, and the remaining coating liquid in the hard guide tube 5, the soft guide tube 6 and the head of the brush body 4 drips back into the storage bottle 1 with the air pressure to be recovered. At the same time, this operation can prevent the liquid outlet of the soft guide tube 6 from being blocked when using volatile liquids, thereby avoiding waste of products and materials.
