Description

Technical Field

[0001] This utility model relates to the technical field of cosmetic storage containers, and more specifically, it relates to a liquid dispensing hose. Background Technology

[0002] In existing tubes used for storing cosmetics, during the emulsion dispensing process, some of the exposed emulsion flows back into the tube due to atmospheric pressure, causing contamination of the emulsion inside the tube.

[0003] In response to this problem, the applicant disclosed a backflow prevention hose (publication number CN215501690U). By setting a blocking structure between the hose and the dispensing nozzle, the emulsion dispensing is cut off, preventing the emulsion from flowing back and contaminating the original liquid, and also improving the comfort of consumers.

[0004] The blocking structure is made of silicone. This tube can only block the flow of cream-type cosmetic emulsions, but it cannot block the flow of thin cosmetic emulsions to prevent backflow.

[0005] To address the aforementioned issues, the applicant has developed a cosmetic product that can achieve the goal of intercepting the flow of the aforementioned sparse water-based emulsions. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a liquid dispensing tube with a reasonable and simple structure, strong practicality, and the ability to meet the requirements of water-based emulsion cosmetics.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A liquid outlet hose includes a hose and a cap. The hose has a cavity for containing a medium, and an outlet for the medium to flow out at one end of the hose. The cap is placed on the end of the hose to seal the outlet. A connecting component is provided on the outlet, and an inner cavity communicating with the outlet is formed within the connecting component. A unit component is connected within the inner cavity.

[0009] The unit has a liquid outlet channel that runs through its body. The outlet is equipped with a ball bearing so that when the medium flows out of the outlet, it pushes the ball bearing away from the outlet and the medium flows out of the unit through the liquid outlet channel. If the medium does not flow, the ball bearing seals the outlet to achieve flow interception.

[0010] The present invention is further configured such that: a limiting component is provided in the liquid outlet channel to restrict the continued displacement of the ball, and the limiting component is at least two protrusions that stretch toward the center of the liquid outlet channel.

[0011] The present invention is further configured such that: an inwardly recessed groove is provided on the outer end face of the liquid outlet, and the inner wall of the groove is arc-shaped so that the ball falls into the groove and partially extends into the liquid outlet.

[0012] The present invention is further configured such that: the inner cavity is provided with a stepped portion for the bottom of the unit to abut against.

[0013] The present invention is further configured such that: the inner peripheral wall of the inner cavity is provided with an annular groove, and the outer peripheral wall of the unit is provided with an annular protrusion adapted to the annular groove.

[0014] The present invention is further configured such that: the unit component has a shoulder that presses against the port of the connecting component.

[0015] The present invention is further configured such that the part of the unit body outside the connecting component is frustum-shaped.

[0016] The present invention is further configured such that: a flow-limiting step is provided in the port for the medium to flow out of the liquid outlet channel.

[0017] The present invention is further configured such that: the cap has a sealing pin extending from the liquid outlet port.

[0018] Compared with the shortcomings of the prior art, the beneficial effects of this utility model are as follows:

[0019] It adopts a ball seal structure, which can effectively prevent backflow of the medium, limit the flow rate of the medium, and prevent the medium from splashing.

[0020] It is safe to use and easy to operate. Moreover, the hose will flatten after each use, making it easy to know the amount of medium in the hose. Attached Figure Description

[0023] Hose 1, cap 2, outlet 10, inner cap 22, outer cap 21, connecting component 11, unit 3, ball bearing 4, settling tank 101, limiting component 31, flow limiting step 32, outlet channel 30. Detailed Implementation

[0024] Reference Figures 1 to 2 The embodiments of this utility model will be further described.

[0025] The specific structure of this utility model includes a flexible tube 1 and a cap 2. The flexible tube 1 has a cavity for containing a medium. At the end of the flexible tube 1, there is an outlet 10 for the medium to flow out. The cap 2 is placed on the end of the flexible tube 1 to seal the outlet 10. The cap 2 includes an inner cap 22 and an outer cap 21. The outer cap 21 is fitted outside the inner cap 22. There is an internal thread inside the inner cap. A connecting component 11 is provided on the outlet 10. An inner cavity communicating with the outlet 10 is formed in the connecting component 11. A unit 3 is installed in the inner cavity. An external thread is provided on the outer peripheral wall of the connecting component 11. The inner cap of the cap 2 and the connecting component 11 are connected by threads.

[0026] In order to achieve stable installation of unit 3, a stepped part is provided on the inner cavity for the bottom of unit 3 to abut against, and an annular groove is also provided on the inner peripheral wall of the inner cavity. An annular protrusion adapted to the annular groove is provided on the outer peripheral wall of unit 3. A shoulder is provided on unit 3 to press against the port of connecting component 11 to prevent unit 3 from shaking in connecting component 11.

[0027] Unit 3 has a liquid outlet channel running through its body. A ball bearing 4 is installed at the outlet 10. The ball bearing 4 is typically made of PE or PP material. When the medium flows out of the outlet 10, it pushes the ball bearing 4 away from the outlet 10, allowing the medium to flow out of unit 3 through the outlet channel. If the medium is not flowing, the ball bearing 4 seals the outlet 10, achieving flow control. During the discharge of the medium, air in the hose 1 is also discharged, creating a negative pressure lower than the external air pressure, thus preventing the backflow of the emulsion.

[0028] The outlet channel is equipped with a limiting component 31 to restrict the continued displacement of the ball 4. The limiting component 31 consists of three protruding strips evenly distributed around the inner peripheral wall of the outlet channel 30 and extending towards the center of the outlet channel 30. The ends of the three protruding strips form support points for limiting the ball 4. The purpose of these three protruding strips is to limit the ball 4 and also to prevent the ball 4 from getting stuck in the outlet channel 30 due to excessive medium pressure.

[0029] The outer end face of the liquid outlet 10 is provided with an inwardly recessed groove 101. The inner wall of the groove 101 is arc-shaped so that the ball 4 falls into the groove 101 and partially extends into the liquid outlet 10, thereby improving the sealing effect.

[0030] The part of the unit 3 outside the connecting part 11 is truncated cone-shaped, and the port of the liquid outlet channel 30 for the medium to flow out is provided with a flow limiting step 32 to limit the flow rate of the medium and prevent the medium from splashing. The cover 2 has a sealing pin 2a that extends from the port of the liquid outlet channel 30.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
