Description

Technical Field

[0001] This utility model relates to the technical field of liquid or gel coating devices, specifically a slow-flow bottle brush connected liquid coating device. Background Technology

[0002] Traditional liquid or gel coating equipment typically includes a reservoir and a roller head connected to the reservoir. The reservoir and roller head are usually connected by threads. After manufacturing, the manufacturer fills the reservoir with liquid and then seals the opening of the reservoir cap with aluminum foil to ensure a tight seal during transport. However, this traditional aluminum foil seal requires additional punching or tearing to open the container, increasing operational complexity and potentially causing debris contamination. Furthermore, the reservoir opening diameter remains constant, and a large opening often leads to uneven coating due to excessively high flow rates. Additionally, the reservoir cap opening cannot effectively control the liquid flow rate, or requires additional complex components for flow adjustment, resulting in operational inconvenience. Utility Model Content

[0003] The purpose of this invention is to provide a slow-flow bottle brush connected liquid coating device to solve the problems mentioned in the background art regarding existing liquid or gel coating devices. These problems include the need to punch or tear open the aluminum foil seal at the bottle opening for activation, increasing operational complexity and potentially causing debris contamination; the fixed opening diameter of the liquid storage tank, and the problem that a large opening often leads to uneven coating due to excessively high flow rates; and the inability to effectively control the liquid flow rate through the liquid storage tank cap opening, or the need for additional complex components for flow adjustment, resulting in inconvenient operation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a slow-flow bottle brush connected liquid coating device, comprising a liquid storage tank and a roller brush head threadedly connected to the liquid storage tank. The liquid storage tank is made of a soft material and has a bottle cap opening. A soft sealing plug is fitted over the bottle cap opening. An outwardly extending column is provided at the center of the soft sealing plug. A liquid outlet hole communicating with the liquid storage tank is provided at the center of the extending column. A detachable plum blossom sealing plug is inserted into the liquid outlet hole. A straight liquid outlet channel is provided at the center of the plum blossom sealing plug, which is initially closed but can be opened when the liquid storage tank is squeezed.

[0005] Preferably, for ease of assembly, the brush head includes a brush seat and a brush cylinder hinged to the front end of the brush seat. The brush seat has an internal thread on the side facing the bottle cap opening. The center of the internal thread has a drain hole that communicates with the brush cylinder. The drain hole communicates with the liquid outlet. The outer side of the bottle cap opening has an external thread that mates with the internal thread.

[0006] Preferably, the plum blossom sealing plug includes a plum blossom base, and the side of the plum blossom base facing the inside of the liquid storage tank is integrally formed with a rising valve core. The rising valve core has a U-shaped structure, and a straight liquid outlet channel is provided at the bottom of the rising valve core.

[0007] Preferably, in order to limit the position of the plum blossom sealing plug, the roller brush seat is provided with one or more limiting slots on the side facing the bottle cap opening. The limiting slots are distributed in a ring on the roller brush seat with the drain hole as the center, and the limiting slots engage with the petals on the side of the plum blossom sealing plug.

[0008] Preferably, a transparent observation window is provided on both sides of the liquid storage tank to check the internal liquid condition.

[0009] Preferably, a trapezoidal flow channel is provided between the soft sealing plug and the extension column to guide the liquid flow.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The addition of a detachable plum blossom sealing plug 8 allows the user to remove it before use, achieving a slow liquid outflow effect from the bottle opening. The small orifice design ensures a significant reduction in the liquid or gel flow rate, enabling gradual and uniform coating. Furthermore, when using the plum blossom sealing plug, the straight-line liquid outlet channel only opens when the reservoir is squeezed, allowing for precise control of the liquid or gel outflow rate and achieving slow-flow liquid dispensing. The plum blossom plug structure is simple and reliable, replacing traditional aluminum foil seals without requiring additional tools or operations, improving user convenience and efficiency, ultimately significantly improving coating uniformity, reducing paint waste, enhancing the user experience, and minimizing uneven coating caused by excessive liquid flow. Moreover, it eliminates the need for additional complex components for flow adjustment, simplifying the coating tool structure and reducing production and usage costs. Attached Figure Description

[0022] Example 1

[0023] Please see Figures 1-8As shown in this embodiment, a slow-flow bottle-brush connected liquid coating device includes a liquid storage tank 1 and a roller brush head 2 threadedly connected to the liquid storage tank 1. The liquid storage tank 1 is made of a soft material and has a bottle cap opening 3. A soft sealing plug 4 is fitted onto the bottle cap opening 3. The soft sealing plug 4 is made of thermoplastic elastomer (TPE). An outwardly extending extension post 5 is provided at the center of the soft sealing plug 4, and the center of the extension post 5 is connected to the liquid storage tank 1. The liquid outlet hole 6 is fitted with a detachable plum blossom sealing plug 8. The center of the plum blossom sealing plug 8 is provided with a straight liquid outlet channel 7 that is initially closed but can be opened when the liquid storage tank 1 is squeezed. The plum blossom sealing plug 8 includes a plum blossom base 801. The side of the plum blossom base 801 facing the inside of the liquid storage tank 1 is integrally formed with a riser valve core 802. The riser valve core 802 has a U-shaped structure and the straight liquid outlet channel 7 is provided at the bottom of the riser valve core 802.

[0024] In order to guide the liquid flow, a trapezoidal guide groove 9 is provided between the soft sealing plug 4 and the extension column 5. The trapezoidal guide groove 9 allows the liquid to flow from the storage tank 1 into the trapezoidal guide groove 9 first, and then into the extension column 5, thereby improving the guiding effect and enabling rapid liquid discharge in the later stage.

[0025] Preferably, for ease of assembly, the roller brush head 2 includes a roller brush seat 201 and a roller brush cylinder 202 hinged to the front end of the roller brush seat 201. The roller brush seat 201 has an internal thread portion 203 on the side facing the bottle cap opening 3. The center of the internal thread portion 203 has a drain hole 204 that communicates with the roller brush cylinder 202. The drain hole 204 communicates with the liquid outlet hole 6. The outer side of the bottle cap opening 3 has an external thread portion 301 that mates with the internal thread portion 203. This structure enables quick disassembly and assembly of the roller brush head 2 and the liquid storage tank 1.

[0026] Preferably, in order to limit the plum blossom sealing plug 8, the roller brush seat 201 is provided with one or more limiting grooves 10 on the side facing the bottle cap opening 3. The limiting grooves 10 are distributed in a ring on the roller brush seat 201 with the drain hole 204 as the center, and the limiting grooves 10 engage with the petals on the side of the plum blossom sealing plug 8. With the above structure, when the roller brush seat 201 is assembled with the liquid storage tank 1, the side of the plum blossom sealing plug 8 can be locked in the limiting groove 10, thereby limiting the plum blossom sealing plug 8 and further preventing the plum blossom sealing plug 8 from falling off under pressure.

[0027] Preferably, in order to check the internal liquid condition, a transparent observation window 101 is provided on both sides of the liquid storage tank 1. By setting the transparent observation window 101, when the liquid storage tank 1 is inverted, if the liquid level inside the liquid storage tank 1 is lower than the transparent observation window 101, it indicates that the liquid in the liquid storage tank 1 is insufficient. Therefore, this structure makes it convenient to check the liquid condition of the liquid storage tank 1.

[0028] In this embodiment, taking a 300g liquid storage tank 1 as an example, the liquid storage tank 1 is made of high-elasticity polyethylene (PE) material to facilitate manual squeezing to control the pressure inside the bottle. The plum blossom sealing plug is made of soft elastic silicone material. In this structure, a soft sealing plug 4 is first covered at the bottle cap opening 3, and then a plum blossom sealing plug 8 is inserted into the soft sealing plug 4 to achieve effective sealing of the liquid outlet hole 6. This can replace the traditional aluminum foil seal, eliminating the need for aluminum foil sealing and avoiding the extra steps of tearing or puncturing, which increases the complexity of operation and may cause debris contamination. In addition, it can further effectively slow down the liquid flow rate. After the user pulls out the plum blossom sealing plug 8, the liquid storage tank 1 is precisely connected to the roller brush head 2, making the operation convenient and quick. Since the size of the liquid outlet hole 6 is smaller than that of the existing bottle cap opening 3, it can achieve slow and uniform liquid or gel dispensing, ultimately achieving the effect of uniform liquid coating.

[0029] Therefore, this structure has the following advantages: The addition of a detachable plum blossom sealing plug 8 allows the user to remove it before use, achieving a slow liquid outflow from the bottle opening. The small orifice design ensures a significant reduction in liquid or gel flow rate, enabling gradual and uniform coating. Furthermore, when using the plum blossom sealing plug 8, the straight-line liquid outlet channel 7 only opens when the storage tank 1 is squeezed, allowing for precise control of the liquid or gel outflow rate and achieving slow-flow liquid dispensing. The plum blossom plug structure is simple and reliable, replacing traditional aluminum foil seals without requiring additional tools or operations, improving user convenience and efficiency, ultimately significantly improving coating uniformity, reducing paint waste, enhancing the user experience, and minimizing uneven coating caused by excessive liquid flow. Moreover, it eliminates the need for additional complex components for flow adjustment, simplifying the coating tool's structure and reducing production and usage costs.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
