Description

TECHNICAL FIELD

[0001] The utility model relates to ball medicine applying technical field, concretely is a medicine applying ball structure that can alleviate liquid tension. BACKGROUND

[0002] The ball medicine applicator is a tool designed specifically for applying medicine directly to the scalp, which usually contains one or more balls that can help the medicine distribute evenly and penetrate into the scalp.

[0003] The ball medicine applicator on the market has a common problem, that is, due to the influence of liquid tension, the ball catheter is prone to generate bubbles that cannot be eliminated, so that the medicine liquid cannot be uniformly delivered to the ball position through the ball catheter, and the indirect medicine liquid cannot be continuously and evenly applied to the patient's affected area, so the best treatment effect cannot be achieved.

[0004] When the medicine liquid tank plastic part containing the ball assembly uses ultrasonic welding process, the spring limiting ring is easily displaced by high-frequency vibration, causing the pre-compression distance of the spring to change, and thus the pressure value of the ball also changes, even causing the ball to be stuck and unable to roll smoothly, and the medicine applying function fails. Therefore, a large part of the medicine liquid tank on the market uses a ball assembly after installation process, and cannot use a more convenient ball assembly and medicine liquid tank sleeve process. UTILITY MODEL CONTENTS

[0005] To solve the above technical problems, the utility model provides a medicine applying ball structure capable of alleviating liquid tension, comprising a medicine liquid tank, a medicine inlet is formed at the top of the medicine liquid tank, and a ball assembly is arranged inside the medicine liquid tank.

[0007] According to the above technical solution, the ball is pressed, the ball presses the pressure spring, a gap is generated between the ball and the inner wall of the ball catheter, at this time, the medicine liquid inside the medicine liquid tank and the ball catheter can flow out uniformly from the gap, and the top of the limiting spring ring is connected to the circular step inside the liquid pressing tank, so that the best position of the limiting spring ring is not changed.

[0008] The diameter of the ball catheter is greater than 3 mm.

[0009] According to the above technical solution, the inner diameter of the ball catheter is set to be not less than 3 mm in diameter, so as to reduce the liquid tension.

[0010] The torque of the pressure spring is 50±20gf.

[0011] By the technical scheme, the user can dispense liquid without pressing hard

[0012] The opening on the surface of the spring limiting ring penetrates the upper and lower ends of the spring limiting ring.

[0013] By the technical scheme, the non-complete circle plus an opening can further break the balance of liquid tension, so that the liquid can smoothly enter the ball guide pipe.

[0014] The depth of the concave opening is greater than or equal to one third to one half of the height of the spring limiting ring.

[0015] By the technical scheme, the depth of the concave opening is greater than or equal to one third to one half of the height of the spring limiting ring, which further reduces the tension of the liquid at the opening of the ball guide pipe.

[0016] Compared with the prior art, the utility model has the beneficial effects that:

[0017] The utility model discloses a ball guide pipe and pressure spring are set up, because the ball guide pipe inner diameter set value is not less than diameter 3mm, liquid tension is reduced, and the torque of the pressure spring is 50±20gf, so that the user can dispense liquid without pressing hard, the spring limiting ring is a non-closed complete ring, an opening is arranged at the top of the spring limiting ring, and a concave opening is arranged opposite the opening, and the depth of the concave opening is greater than or equal to one third to one half of the height of the spring limiting ring, which further reduces the tension of the liquid at the opening of the ball guide pipe, breaks the balance of liquid tension, and makes the liquid smoothly enter the ball guide pipe.

[0018] The utility model discloses a ball guide pipe and pressure spring are set up, because the ball guide pipe inner diameter set value is not less than diameter 3mm, liquid tension is reduced, and the torque of the pressure spring is 50±20gf, so that the user can dispense liquid without pressing hard, the spring limiting ring is a non-closed complete ring, an opening is arranged at the top of the spring limiting ring, and a concave opening is arranged opposite the opening, and the depth of the concave opening is greater than or equal to one third to one half of the height of the spring limiting ring, which further reduces the tension of the liquid at the opening of the ball guide pipe, breaks the balance of liquid tension, and makes the liquid smoothly enter the ball guide pipe.
