[0023] The present invention will now be described in detail with reference to the accompanying drawings.
[0024] like Figures 1 to 2As shown, the present invention discloses a circuit board assembly structure for a foundation pump, comprising a bottle body 1, a bottle cap 2 disposed on the bottle body 1, a pump body 3 disposed on the bottle cap 2, a liquid extraction tube 4 disposed on the pump body 3, a circuit board 21 disposed on the bottle cap 2, a switch button 22 electrically connected to the circuit board 21, and a control valve 23 disposed between the pump body 3 and the liquid extraction tube 4. The control valve 23 is signal-connected to the circuit board 21. The bottle cap 2 includes an inner cavity 24, a locking groove 25 disposed on the inner cavity 24, and a through hole 26 disposed on the inner cavity 24. The circuit board 21 is accommodated in the locking groove 25. The circuit board 21 is provided with a micro switch 27. One end of the switch button 22 is connected to the micro switch 27, and the other end of the switch button 22 passes through the through hole 26 and protrudes out of the bottle cap 2.
[0025] The top outer wall of the bottle body 1 is provided with external threads, and the inner wall of the bottle cap 2 is provided with internal threads. The detachable connection between the bottle cap 2 and the bottle body 1 is achieved by means of the threaded connection between the external and internal threads. One end of the switch button 22 is connected to the micro switch 27, and the other end of the switch button 22 passes through the through hole 26 and protrudes out of the bottle cap 2, so that the switch button 22 is exposed outside the bottle cap 2 for easy pressing to start and stop use. When the user presses the switch button 22 for the first time, the pressure of the switch button 22 triggers the micro switch 27. Since the control valve 23 is connected to the circuit board 21, the micro switch 27 immediately transmits the signal to the circuit board 21. After the circuit board 21 analyzes and processes the signal, it automatically controls the control valve 23 to open, connecting the pump body 3 and the liquid extraction tube 4. When the pump body 3 is pressed, the foundation liquid enters the pump body 3 through the liquid extraction tube 4 for easy dispensing. When the user presses the switch button 22 again, the circuit board 21 automatically controls the control valve 23 to close, disconnecting the connection between the pump body 3 and the liquid extraction tube 4. Even if the pump body 3 is pressed, no foundation liquid will be dispensed. The design of the micro switch 27 makes the operation of the control valve 23 more flexible and controllable, allowing it to be started or stopped at any time according to actual usage, effectively avoiding accidents caused by incorrect operation and improving safety. The control valve 23 includes solenoid valves, flow valves, etc., among which the solenoid valve is the most common type. It controls the flow of liquid by energizing or de-energizing a coil, and has the advantages of fast response and high reliability. This utility model realizes intelligent start-stop control of the pump body 3, which is convenient and efficient to operate, effectively avoids the waste of foundation liquid caused by accidental pressing, and provides a more advanced user experience.
[0026] In this embodiment, a through groove 28 is provided in the middle of the bottle cap 2. A locking block 29 is provided on the inner wall of the through groove 28. A sealing ring 210 is provided at the bottom of the bottle cap 2. The sealing ring 210 fits against the top of the bottle body 1. The pump body 3 passes through the through groove 28 and protrudes into the bottle body 1 so that the locking block 29 engages and fixes the pump body 3. Specifically, the through groove 28 is provided in the middle of the bottle cap 2 so that the pump body 3 can pass through the through groove 28 and protrude into the bottle body 1. At the same time, the locking block 29 provided on the inner wall of the through groove 28 engages and is fastened to the outer wall of the pump body 3, enhancing the connection stability between the pump body 3 and the bottle cap 2 and preventing the pump body 3 from loosening and falling off.
[0027] In this embodiment, the bottle cap 2 is provided with vertical stripes 211, which are arranged around the circumference of the bottle cap 2. Specifically, multiple vertical stripes 211 are provided, and the multiple vertical stripes 211 are arranged around the circumference of the bottle cap 2. The main purpose of the vertical stripes 211 on the bottle cap 2 is to increase the roughness of the contact surface to increase the friction, prevent the user's hand from slipping when holding the bottle cap 2, adapt to different hand shapes and gripping methods, provide a better gripping experience, and make it easier to grip the bottle cap 2 and apply force, thereby opening the bottle cap 2 smoothly and improving the safety of use.
[0028] The pump body 3 in this embodiment includes a sleeve 31, an infusion tube 32 disposed on the sleeve 31, a spring 33 sleeved on the outside of the infusion tube 32, and a pressure head 34 connected to the infusion tube 32. The sleeve 31 is provided with a first annular boss 35 and a second annular boss 36 spaced apart. The spring 33 stops and abuts against the first annular boss 35, and the control valve 23 stops and abuts against the second annular boss 36. Specifically, the infusion tube 32 is inserted and housed in the sleeve 31, the spring 33 is sleeved on the outside of the infusion tube 32, and the spring 33 stops and abuts against the first annular boss 35, providing a good elastic restoring effect for the infusion tube 32. The control valve 23 stops and abuts against the second annular boss 36, providing a good position fixing effect for the control valve 23, so that the foundation liquid can pass through the suction tube 4, the control valve 23 and then enter the infusion tube 32, and then be squeezed out and used by the pressure head 34.
[0029] In this embodiment, the bottom of the engaging groove 25 is provided with a mounting base 212, and mounting screws 213 are provided on both sides of the mounting base 212. Specifically, the engaging groove 25 is placed on the mounting base 212, and two mounting screws 213 are used to pass through both sides of the engaging groove 25 and then connect and fix it to the mounting base 212, so that the engaging groove 25 is connected and fixed to the inner cavity 24 through the mounting base 212, and the connection is stable and reliable.
