[0002] The prior art (publication number: CN 221893649 U) discloses a skin care product tube with a leak-proof function, including a tube body and a tube cap. A tube head is fixedly connected to one side of the tube body. Two inner grooves are opened inside the tube head. A first spring is fixedly connected to one side of each of the two inner grooves. A fixing block is fixedly connected to one end of each of the two first springs. A connecting rod is fixedly connected between the two fixing blocks. A ball bearing is rotatably connected to the outside of the connecting rod.

[0003] While the aforementioned patent utilizes a roller that adheres to and presses against the skin to dispense skincare products, minimizing excess product and waste, and facilitating product application, it suffers from several drawbacks. The fixed size of the groove prevents flexible adjustment of the dispensing volume, especially when the roller is gently rotated, potentially leading to excessive product flow and waste. Further improvements are needed, hence the proposed solution: a flowing liquid application device. Utility Model Content

[0004] The main objective of this invention is to provide a fluid application device that can effectively solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A fluid application device includes a tube body with a spring installed at the middle of its upper end. The tube body has a cavity and a spherical cavity sequentially formed from top to bottom. A top cover is movably connected to the upper end of the spring. A ball bearing is movably fitted inside the spherical cavity. A lifting rod is installed on the inner wall of the top cover. The lower end of the lifting rod is movably inserted into the cavity. A first circular plate is threaded onto the lower part of the outer surface of the lifting rod. The outer surface of the first circular plate is fixedly connected to the cavity. A second circular plate is fixedly connected to the lower part of the inner wall of the cavity. A through groove is formed at the upper end of the second circular plate. A receiving cavity is formed on the right inner wall of the through groove. A baffle is slidably connected inside the receiving cavity. The baffle can slide left and right to adjust the size of the through groove.

[0007] Preferably, a rectangular groove is formed inside the tube body, and an adjusting component is provided inside the rectangular groove. The adjusting component is used to drive the baffle to move. The adjusting component includes a rotating rod, which is set inside the rectangular groove. The right end of the rotating rod is movably inserted to the right side of the tube body, and the left end of the rotating rod is rotatably connected to the left wall of the rectangular groove. A first gear is fixedly sleeved on the left side of the outer surface of the rotating rod. The first gear is meshed with a second gear, which is rotatably connected to the left wall of the rectangular groove. A lead screw is threaded inside the second gear.

[0008] Preferably, the left end of the lead screw is movably inserted into the receiving cavity and fixedly connected to the right end of the baffle.

[0009] Preferably, the second circular plate is located below the first circular plate.

[0010] Preferably, a first bevel tooth is fixedly sleeved on the outer surface of the rotating rod, the first bevel tooth is meshed with a second bevel tooth, a third gear is fixedly connected to the lower end of the second bevel tooth, the lower end of the third gear is rotatably connected to the lower wall of the rectangular groove, the third gear is meshed with an arc-shaped rack, and a scale line is provided on the side of the arc-shaped rack away from the third gear.

[0011] Preferably, the front inner wall and the rear inner wall of the rectangular groove are provided with a sliding groove, and the arc-shaped rack is slidably connected in the sliding groove.

[0012] Preferably, a transparent plate is installed on the right inner wall of the rectangular groove, the transparent plate extends to the right side of the tube body, and the transparent plate is located to the right of the scale line.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The size of the through channel can be adjusted by setting baffles and adjusting components. When it is necessary to enlarge the size, rotate the rotating rod to drive the first gear and the second gear to rotate. The second gear drives the screw to move to the right, and the screw drives the baffle to move to the right, thus enlarging the size of the through channel. Conversely, rotating the rotating rod in the opposite direction will reduce the size of the through channel. The discharge amount can be flexibly adjusted during use, avoiding the situation that too much or too little skin care product may flow out, allowing the skin care product to flow out more evenly and in the right amount, reducing waste.

[0015] 2. By setting up an arc-shaped rack, a first bevel gear, a second bevel gear, a third gear, and scale lines in coordination, the size of the adjustment channel can be easily understood. When the rotating rod rotates, it drives the first bevel gear, the second bevel gear, and the third gear to rotate. The third gear drives the arc-shaped rack to rotate, so that the other scale lines are aligned with the transparent plate. The specific size value can be seen through the transparent plate, which helps users intuitively select the output amount, ensuring that the amount of skin care products used each time meets the requirements, achieving precise control, and avoiding problems of too much or too little.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1-5 As shown, a fluid application device includes a tube body 1. Four springs 5 ​​are installed at the upper middle part of the tube body 1. The tube body 1 has cavities 4 and spherical cavities 7 arranged sequentially from top to bottom. The cavity 4 contains an essence. A top cover 2 is movably connected to the upper end of each spring 5. A ball bearing 8 is movably fitted inside the spherical cavity 7. A lifting rod 3 is installed on the inner wall of the top cover 2. The lower end of the lifting rod 3 movably inserts into the cavity 4. A first circular plate 6 is threaded onto the lower part of the outer surface of the lifting rod 3. The outer surface of the first circular plate 6 is fixedly connected to the cavity 4. Next, when in use, rotate the top cover 2. The top cover 2 moves the lifting rod 3 away from the first circular plate 6, allowing the purified liquid to flow into the spherical cavity 7. The spring 5 moves the top cover 2 upward to prevent it from moving downward. Use the ball bearing 8 to roll against the skin so that the essence can be applied to the skin. However, the size of the screw hole in the first circular plate 6 cannot be adjusted. The fixed size screw hole cannot flexibly adjust the discharge amount during use. Especially when gently rotating the ball bearing 8, too much skin care product may flow out, resulting in rapid consumption and waste.

[0026] To address the aforementioned drawbacks, a second circular plate 9 is fixedly connected to the lower part of the inner wall of cavity 4. The second circular plate 9 is located below the first circular plate 6. A through groove 10 is provided at the upper end of the second circular plate 9. A receiving cavity 15 is provided on the right inner wall of the through groove 10. A baffle 11 is slidably connected inside the receiving cavity 15. By driving the baffle 11 to slide left and right, the size of the through groove 10 can be adjusted, thereby adjusting the amount of purified liquid entering the spherical cavity 7.

[0027] To move the baffle 11 left and right, a rectangular groove 12 is provided inside the tube body 1. An adjusting component 13 is installed inside the rectangular groove 12 to move the baffle 11. The adjusting component 13 includes a rotating rod 131, which is located inside the rectangular groove 12. The right end of the rotating rod 131 is movably inserted to the right side of the tube body 1, and the left end of the rotating rod 131 is rotatably connected to the left wall of the rectangular groove 12 via a bearing. A first gear 132 is fixedly sleeved on the left side of the outer surface of the rotating rod 131. The first gear 132 is meshed with a second gear 133. The first gear 132 and the second gear 133 are distributed front and back. The second gear 133 is rotatably connected to the left side of the rectangular groove 12 via a bearing. On the wall, the internal thread of the second gear 133 is fitted with a lead screw 134. The left end of the lead screw 134 is movably inserted into the receiving cavity 15 and fixedly connected to the right end of the baffle 11. When the size needs to be enlarged, rotating the rotating rod 131 drives the first gear 132 to rotate, the first gear 132 drives the second gear 133 to rotate, the second gear 133 drives the lead screw 134 to move to the right, and the lead screw 134 drives the baffle 11 to move to the right, thus enlarging the size of the through groove 10. Conversely, rotating the rotating rod 131 in the opposite direction can reduce the size of the through groove 10. During use, the discharge amount can be flexibly adjusted to avoid the situation where too much or too little skin care product may flow out, so that the skin care product flows out more evenly and in appropriate amount, reducing waste.

[0028] Furthermore, since the dimensional changes of the through groove 10 cannot be observed from the outer surface of the tube body 1, affecting the user's adjustment of the through groove 10's dimensions, a first bevel tooth 18 is fixedly sleeved on the outer surface of the rotating rod 131 to allow for understanding the size of the through groove 10. The first bevel tooth 18 is meshed with a second bevel tooth 19, and a third gear 20 is fixedly connected to the lower end of the second bevel tooth 19. The lower end of the third gear 20 is rotatably connected to the lower wall of the rectangular groove 12. The third gear 20 is meshed with an arc-shaped rack 17, and a scale line is provided on the side of the arc-shaped rack 17 away from the third gear 20. The front inner wall and rear inner wall of the rectangular groove 12 are both provided with a sliding groove 16, and the arc-shaped rack 17 is slidably connected to the groove via a slide rail. Inside the chute 16, a transparent plate 14 is installed on the right inner wall of the rectangular groove 12. The transparent plate 14 extends to the right side of the tube body 1 and is located to the right of the scale line. When the rotating rod 131 rotates, the rotating rod 131 drives the first bevel tooth 18 to rotate. The first bevel tooth 18 drives the second bevel tooth 19 and the third gear 20 to rotate. The third gear 20 drives the arc-shaped rack 17 to rotate, so that the scale line that matches the size of the through groove 10 is aligned with the transparent plate 14. The value of the scale line can be read through the transparent plate 14, thereby understanding the specific size value of the through groove 10. This helps users intuitively select the discharge amount, ensuring that the amount of skin care product used each time meets the requirements, achieving precise control, and avoiding problems of too much or too little.
