[0029] Hereinafter, the present invention will be described in detail with reference to the drawings and the embodiments:
[0030] Such as Figure 1-3 As shown, an automatic suction bottle cap is mainly composed of a cap shell 1, a motor 33, a roller 32, a controller 36, a power supply 37, a flexible straw 4 and a stopper 5. There is a groove on the upper surface of the cap shell 1. , The motor 33, the roller 32, the controller 36, and the power supply 37 are all placed in the groove. The controller 36 controls the operation of the motor 33. The power supply 37 and the controller 36 are connected together, and the power supply 37 is used for the electronics in the bottle cap. The device provides power. The motor 33 is fixed with the driving wheel 31 through a rod. The roller 32 is in contact with the driving wheel 31, and the driving wheel 31 is driven to rotate by the rotation of the motor, and the driving wheel 31 takes the roller 32 to roll.
[0031] A control board cover 3 is fixed on the groove of the bottle cap shell 1, and the control board cover 3 covers the groove to avoid exposure of the motor 33, the controller 36, and the power source 37, making the bottle cap more beautiful; The plate cover 3 is provided with a display screen 34 and a button 35, both the display screen 34 and the button 35 are connected to the controller 36, the rotation of the motor 33 is controlled by the button 36, and the working condition of the bottle cap is understood through the display screen 34.
[0032] The bottle cap shell 1 also includes a vent 2 and a bottle mouth 13. The bottle mouth 13 is set on the side of the bottle cap shell 1. The bottle mouth 13 is connected to the water outlet 41 at one end of the flexible straw 4, and the vent 2 is Set on the upper surface of the bottle cap shell 1, the vent hole 2 penetrates through the bottle cap shell 1, and the vent hole 2 is located on the opposite side of the bottle mouth 13, ensuring that when the liquid is poured, the liquid will not pass through the vent hole 2 The water inlet 42 at the other end of the flexible straw 4 is inserted into the bottle. The end of the flexible straw 4 close to the water outlet 41 is provided with a flow sensor 43. The flow sensor 43 can accurately monitor the flow of liquid, and the flow sensor 43 will The monitored data is fed back to the display screen 34, so that the user can clearly understand the amount of liquid in the bottle, so that the user can accurately extract the liquid. Install the flow sensor 43 on the flexible straw 4 near the water outlet 41 for a more intuitive understanding To the amount of liquid that has been drawn (the amount of liquid that the user has already received).
[0033] Such as Figure 4 As shown, the inner ring of the bottle cap shell 1 is provided with a bottle cap thread 12, which can be engaged with the thread on the outside of the bottle mouth, and the bottle body and the automatic suction bottle cap are tightly connected together. It can play a very good sealing effect and prevent the liquid from flowing out of the gap between the bottle cap shell 1 and the bottle mouth when the bottle is poured. A water level sensor 14 is installed at the bottom center of the bottle cap shell 1, and the water level sensor 14 is connected to the controller 36 The water level sensor 14 monitors the amount of liquid in the bottle in real time, and feeds back real-time liquid level data on the display screen 34 for users to view.
[0034] Such as Figure 5 Shown is a partial cross-sectional view of the automatic suction bottle cap of a specific embodiment. In this specific embodiment, there are three rollers 32. The inside of the cap shell 1 is provided with a stop ring 11, and the rollers 32 and driving wheels 31 are placed In the limit ring 11, when the driving wheel 31 rotates, the roller 32 is driven to rotate. At the same time, because the roller 32 is in contact with the inner ring of the limit ring 11, the roller 32 rotates along the limit ring 11 under the action of friction. The upper surface of the limit ring 11 is fixed with a stopper 5, the side of the stopper 5 close to the roller 32 and the driving wheel 31 is an arc shape, and the arc side of the stopper 5 and the inner ring of the limit ring 11 are concentric circles, At the same time, it is satisfied that the wall thickness of the flexible straw 4 with the arc side of the roller 32 and the stop 5 is not more than twice, which ensures that when the roller 32 squeezes the flexible straw 4, the flexible straw 4 at the squeezed position must be under negative pressure, preventing the flexible straw 4 Insufficient squeezing affects the movement of the liquid in the flexible straw 4, where the length of the stopper 5 and the number of rollers 32 follow the arc length of the arc side of the stopper 5 and the arc length is not less than the distance between two adjacent rollers 32, which can ensure the front Before a roller 32 is out of contact with the flexible straw 4, the latter roller 32 has been in contact with the flexible straw 4, preventing the liquid in the flexible straw 4 from sucking backwards. A section of the flexible straw 4 is closely attached to the stopper 5 On the side of the arc, the flexible straw 4 is placed between the stopper 5 and the roller 32.
[0035] When the motor 33 rotates, it drives the driving wheel 31 to rotate. The driving wheel 31 presses the roller 32 to rotate. When the roller 32 rotates at the stop 5, the roller 32 and the stop 5 squeeze the flexible straw 4, and the flexible straw 4 is completely Negative pressure is formed in the tube after squeezing. When the flexible straw 4 is restored, the hydraulic pressure in the bottle will press the liquid into the flexible straw 4, and the liquid in the bottle will be sucked into the flexible straw 4, just like two fingers squeezing the soft filled with liquid. Like a tube, as the finger moves, negative pressure is formed in the tube, and the liquid flows along with it. The liquid in the flexible straw 4 moves with the rotation direction of the motor 33. At the same time, because the flexible straw 4 is squeezed, the pressure of the flexible straw 4 Smaller, the liquid in the bottle is continuously pressed into the flexible straw 4, thereby completing the liquid extraction process, because the pressure is used to suck the liquid, and the amount of liquid suction is determined by the amount between two adjacent rollers 32 The distance is determined by the inner diameter of the flexible straw 4, so the liquid drawn out is also quantitative under the premise that the distance between two adjacent rollers 32 and the inner diameter of the flexible straw 4 are constant, which ensures that the liquid extraction efficiency is constant , Easier to control the amount of liquid drawn
[0036] Such as Image 6 As shown, the sealing ring 21 fixed in the vent 2 has an annular shape, wherein the inner rings of the sealing ring 21 squeeze each other to act as a seal to prevent liquid leakage or contamination of the liquid in the bottle by sundries. When the motor 33 rotates, the pressure inside the bottle is reduced because the liquid is drawn out. The inside and outside pressures of the sealing ring 21 are different, and the gas can be pressed into the bottle from the gap in the inner ring where the sealing ring 21 pressurizes each other to ensure the same pressure difference between the inside and outside of the bottle. While ensuring the normal operation of the motor 33, it can also prevent damage to the bottle containing the liquid.
[0037] The invention uses the roller and the stopper to pinch the flexible straw to suck the liquid in the bottle into the straw and flow in the straw; the seal ring squeezed each other through the inner ring prevents the liquid in the bottle from being contaminated and ensures that the liquid is drawn in the bottle The pressure outside the bottle is the same to avoid damage to the bottle; the flow sensor is used to monitor the amount of liquid extracted to make the volume of the liquid taken out of the bottle more accurate; the working status of the bottle cap is displayed on the display and the button is used to control the work of the bottle cap. Convenience.
