Description

[Technical Field]

[0001] The present invention relates to the technical field of liquid discharge mechanisms, and more particularly to a liquid discharge mechanism for massage. [Background technology]

[0002] As people become more conscious of their health and quality of life, massage devices are evolving from traditional mechanical massage to multifunctional products that combine intelligent control, precise medication administration, and personalized services. In particular, in the fields of beauty care, medical rehabilitation, and home health care, fluid delivery mechanisms are a core component. These mechanisms precisely and stably deliver pre-filled functional fluids, such as essential oils, moisturizing nutrients, and herbal extracts, to the massage site, thereby relieving fatigue, promoting blood circulation, and facilitating the absorption of medicinal ingredients. Conventional fluid discharge mechanisms mainly use a pressing method using hard materials such as pumps or gears, which can easily cause wear and deterioration of internal parts over long-term use, shortening the device's lifespan and increasing maintenance costs. Furthermore, existing fluid discharge mechanisms only support a single flow rate mode, making it impossible to dynamically adjust the flow rate according to the user's needs or switch between jet and slow release, limiting the flexibility of their application. To address these issues, this invention proposes a fluid discharge mechanism for massage. Summary of the Invention

[0003] The purpose of this invention is to solve the problems pointed out in the background art above, that conventional liquid discharge mechanisms use a pressing method using hard materials such as pumps and gears, which causes internal parts to wear and deteriorate over long-term use, shortening the device's lifespan and increasing maintenance costs, and that liquid discharge mechanisms can only support a single flow rate mode, making it impossible to adjust the flow rate according to the user's needs or switch between spray and slow release, limiting the range of applications.

For example, two drive shafts may be configured in a rectangular shape, three drive shafts in a triangular shape, and other numbers may be configured in various shapes. Two ventilation holes are provided at the bottom of the liquid storage device, and a waterproof ventilation membrane is attached inside each ventilation hole. The rotation mechanism consists of a circuit board fixedly connected to the outer shell, a battery mounted on one side of the circuit board, and a geared motor fixedly connected to the opposite side of the battery.

Furthermore, a fixed cover is fixedly attached to the top of the fixed seat, and the fixed cover is rotatably connected to the upper end of the drive shaft. A geared motor is a variable speed motor with forward and reverse rotation functions, and the drive shaft can be switched between forward and reverse rotation by circuit driving.

[0007] The technical solutions of the embodiments of the present invention will be described clearly and completely below with reference to the drawings of the embodiments. Obviously, the described embodiments are only some of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments that can be obtained by those skilled in the art without creative ingenuity fall within the scope of protection of the present invention.

[0008] The technical means of the present invention will be described below with reference to Figures 1 to 11. The liquid discharge mechanism for massage provided by the present invention comprises an outer shell 1 and the following components: a liquid storage device 2 attached inside the outer shell 1; a sealing silicone member 3 fixedly connected to the outlet of the liquid storage device 2; and a fixed plug 4 detachably connected to the bottom of the liquid storage device 2. A bottom piston 5 slidable in the axial direction is provided inside the liquid storage device 2 and movable along the inner wall. A silicone tube 6 is fixedly connected to the outlet of the liquid storage device 2 and communicates with the sealing silicone member 3. A drive shaft 7 is provided in the middle region of the silicone tube 6, and two or more drive shafts 7 are provided. The sealing silicone member 3 is attached in close contact with the inner wall of the outlet of the liquid storage device 2 to prevent liquid leakage. The fixed plug 4 is used to seal the bottom of the liquid storage device 2. The sliding direction of the bottom piston 5 coincides with the liquid discharge direction and acts in response to changes in internal pressure that occur when liquid is discharged. The silicone tube 6 is a passage for receiving the liquid discharged from the liquid storage device 2, and is made of medical-grade silicone material, which has excellent elasticity and aging resistance. The spacing between the drive shafts 7 is adapted to the diameter of the silicone tube 6, which allows the silicone tube 6 to have an effective compression effect.

[0009] Two ventilation holes 11 are provided at the bottom of the liquid storage device 2, and a waterproof, breathable membrane 12 is attached inside each ventilation hole 11. The waterproof, breathable membrane 12 allows gas to pass through, maintaining equal air pressure inside and outside the container while preventing liquid leakage. These two ventilation holes 11 communicate with the lower part of the bottom piston 5, and when the upper liquid in the liquid storage device 2 is discharged by rotation of the drive shaft 7, the internal pressure of the liquid storage device 2 drops slightly below the external air pressure. As a result, atmospheric pressure pushes the bottom piston 5 upward along the inner wall of the liquid storage device 2. A rotation mechanism 8 is fixedly connected inside the outer shell 1. The rotation mechanism 8 is installed outside the drive shaft 7 and functions as a power source for supplying rotational driving force to the drive shaft 7. The drive shaft 7 is rotated by the rotation mechanism 8, and the drive shaft 7 applies a compressive force to the silicone tube 6, thereby achieving the transport of liquid. As the drive shaft 7 moves, the internal volume of the silicone tube 6 changes, and the resulting pressure difference transports the liquid in a fixed direction. The rotation mechanism 8 is composed of the following: a circuit board 81 fixedly connected to the outer shell 1; a battery 82 is provided on one side of the circuit board 81; and a geared motor 83 is fixedly connected to the opposite side of the battery 82. A fixed base 84 is fixedly provided above the geared motor 83, and the output end of the motor is fixedly connected to the drive shaft 7. Furthermore, a fixed cover 85 is fixedly attached to the top of the fixed base 84, and the fixed cover 85 is rotatably connected to the upper end of the drive shaft 7. The battery 82 supplies power to the rotation mechanism 8, enabling synchronous rotation of the drive shaft 7. The fixed cover 85 also serves to position and stabilize the upper end of the drive shaft 7.

[0010] During use, the battery 82 supplies power to the rotation mechanism 8, and the circuit board 81 controls the geared motor 83 to rotate clockwise, which rotates the drive shaft 7 clockwise and presses against the silicone tube 6, causing a localized portion of the silicone tube 6 wall to dent, reducing the internal cross-sectional area or completely closing it. As the drive shaft 7 continues to rotate forward, the pressure point moves toward the liquid outlet, and the silicone tube 6 behind the pressed area instantly returns to its original shape due to its elasticity, instantly increasing the volume within the tube and creating a negative pressure. The liquid storage device 2 communicates with the silicone tube 6 via the sealing silicone 3, and its interior is sealed by the bottom piston 5. This creates a pressure difference between the pressure within the bottle and the negative pressure within the silicone tube 6, drawing the liquid from the liquid storage device 2 into the silicone tube 6. At the same time, as the liquid in the liquid storage device 2 decreases, negative pressure is generated inside, and the bottom piston 5 moves forward along the bottle wall due to the action of external atmospheric pressure, filling the space created by the outflow of liquid and keeping the pressure inside the bottle stable, so that the liquid is continuously sucked in and transported toward the outlet along with the pressure inside the silicone tube 6, thereby achieving suction, transportation and continuous discharge of the liquid.

[0011] The geared motor 83 is a variable-speed motor with forward and reverse rotation functions, allowing the drive shaft 7 to rotate forward and reverse via a circuit drive. By controlling the rotation speed, the variable-speed motor can output liquid gently or in a jet, making it suitable for a variety of applications. Furthermore, the forward / reverse function allows the rotation mechanism 8 to rotate the drive shaft 7 to discharge liquid during forward rotation, while during reverse rotation, the drive shaft 7 presses the silicone tube 6 from the outlet end toward the liquid storage device 2. Pressing the silicone tube 6 near the outlet side generates a reverse thrust, causing residual liquid and cleaning solution to flow back inside the tube and clean the inner wall of the tube. Furthermore, the negative pressure of the pressing section draws external air and cleaning solution into the silicone tube 6. This, combined with the impact force of the reverse fluid, removes and removes residual substances and impurities adhering to the tube wall, thereby cleaning the inside of the silicone tube 6 and preventing deterioration of the residual liquid and contamination of subsequent liquids.

[0012] The silicone tube 6 is arranged in a U-shape, penetrating between the drive shafts 7. This design increases the contact length and area between the silicone tube 6 and the drive shafts 7, improving the efficiency of liquid transport and making the pressure from the drive shafts 7 more uniform, allowing for appropriate pressure on the silicone tubes 6 and more effective liquid transport and backwashing. An outlet 9 is fixedly connected to the interior of the outer shell 1, and the outlet 9 communicates with one end of a silicone tube 6 remote from the liquid storage device 2. The silicone tube 6 and the outlet 9 are connected by heat sealing or a fitting connection, providing an outlet path for the liquid in the silicone tube 6 and delivering the liquid accurately to the massage site. A charging port 10 is fixedly provided on the outer shell 1, and the charging port 10 allows charging of the battery 82, realizing repeated use of the device and improving the portability and economy of the device.

[0013] The drive shafts 7 may be two, three, four, or any other number, but are not limited to two or more. Various shapes can be configured depending on the number of shafts. For example, two drive shafts 7 may be rectangular, three drive shafts 7 may be triangular, and other numbers may result in irregular shapes. Drive shafts 7 of different shapes can accommodate various pressing requirements. A circular drive shaft 7 provides stable pressing, while an irregularly shaped drive shaft 7 can enhance pressing effect and improve liquid delivery volume. During use, when fluid needs to be discharged, the motor is controlled to rotate clockwise, rotating the drive shaft 7 clockwise to press against the silicone tube 6, creating low pressure that transports the fluid through the silicone tube 6 to the outlet 9 and then to the massage site. The motor's rotation speed can be adjusted during use to allow for either a jet or slow discharge of fluid, flexibly meeting various needs. Furthermore, the cooperation between the silicone tube 6 and the drive shaft 7 effectively prevents wear on the tube and extends the device's service life. After use, the drive shaft 7 is rotated in the reverse direction to press against the silicone tube 6, allowing the air pressure to backwash the silicone tube 6 and ensure hygiene within the tube. The drive shaft 7 may be of a split or one-piece type, but is not limited to these. One-piece drive shafts include rectangular, triangular, and irregular shapes. The split drive shaft 7 allows for the replacement of only the damaged section, eliminating the need to discard the entire shaft and reducing the cost of spare parts. The one-piece drive shaft 7 has high overall rigidity, can withstand greater torque, rotational speed, or axial force, and can reduce vibration and noise caused by loose connections.
