Detailed Implementation

[0017] The present invention will be further described below through specific embodiments, so as to make the technical solution of the present invention easier to understand and master, rather than to limit the present invention.

[0018] Example: See Figures 1 to 5 The embodiment provides a hydrogen peroxide metering device, which includes a device body 1 and several sets of metering pumping mechanisms 2; The device body 1 includes at least two sets of liquid storage chambers, and each of the liquid storage chambers is equipped with a set of the metering pump mechanism 2; The metering pumping mechanism 2 includes a metering section 21, a pumping section 22, and an extraction section 23 arranged in a sealed and connected manner in sequence; the extraction section 23 is preferably, but not limited to, a suction tube; The pumping section 22 includes a negative pressure pumping chamber, and a spring 221 is provided in the negative pressure pumping chamber; The metering unit 21 includes a pressing head 211, a pump rod 212 and an extrusion member 213 arranged in sequence. The extrusion member 213 is adapted to be movably disposed in the negative pressure pumping chamber and abuts against the spring 221. The pump rod 212 is provided with a number of metering points 214 at intervals, so that when the pressing head 211 is pressed down along the pump rod 212 to the position of one metering point 214, the extrusion member 213 extrudes the negative pressure pumping chamber to pump a pumping capacity of liquid.

[0019] Specifically, by adjusting the number of storage chambers, different types and concentrations of liquids can be accommodated, achieving the purpose of convenient solution preparation. Furthermore, the structure of the metering pumping mechanism 2 is innovatively improved, allowing the pumping capacity of liquid to be pumped by pressing down several metering points 214, thereby obtaining the required pumping capacity of liquid through different pressing depths and optimizing the convenience and reliability of metering.

[0020] Preferably, the number of metering points 214 can be set according to actual usage to adjust the actual capacity of the pumping capacity accordingly.

[0021] In this embodiment, there are two sets of storage chambers, which respectively contain 6% hydrogen peroxide and 12% hydrogen peroxide; there are two sets of metering points 214, so that 10 mL of liquid is obtained each time the pressing head 211 descends to the position of a metering point 214.

[0022] Preferably, the lower end of the pump rod 212 is provided with a first sealing mating seat, and the extrusion member 213 is inserted into the first sealing mating seat so that the pump rod 212 and the extrusion member 213 are connected, thereby improving the assembly sealing and reliability between the extrusion member 213 and the pump rod 212.

[0023] Furthermore, the upper end face of the extrusion member 213 is provided with a first positioning groove for positioning the first sealing dock seat, and the lower end face of the extrusion member 213 is provided with a second positioning groove for positioning one end of the spring 221. On the one hand, this improves the transmission reliability and stability of the pump rod 212 to the extrusion member 213, and on the other hand, it ensures that the extrusion member 213 can be directionally pressed down and reset along the negative pressure pumping chamber.

[0024] Preferably, the pumping section 22 further includes a pumping section body, and the negative pressure pumping chamber is disposed inside the pumping section body; The upper end of the pumping unit body is provided with a first sealing locking seat. The first sealing locking seat is sealed to the pump rod 212 through a first sealing cover 3. A first sealing structure 31 is adapted to be provided between the first sealing locking seat, the first sealing cover 3 and the pump rod 212. The first sealing structure extends with a first limiting block corresponding to the first sealing mating seat. Specifically, the first sealing cover 3 is assembled with the first sealing locking seat using a threaded structure. The pump rod 212 and the pumping unit 22 are locked together by the first sealing cover 3. The sealing performance between the pump rod 212 and the pumping unit 22 is improved by the first sealing structure. The first limiting block effectively prevents the pump rod 212 from exceeding the reset stroke.

[0025] Preferably, the pumping unit 22 is detachably mounted on the liquid storage chamber via the second sealing cover 4; A limiting ring platform is provided on the outer peripheral surface of the first sealing locking seat along the circumferential direction, and the second sealing cover 4 is adapted to abut against the limiting ring platform and the first sealing cover 3; specifically, the second sealing cover 4 adopts a threaded structure and is assembled with the liquid storage chamber, and the positioning stability of the second sealing cover 4 is improved by the limiting ring platform.

[0026] Preferably, a suction-stop chamber is provided at the lower end of the pumping unit body, and the suction-stop chamber is connected to the extraction unit 23; The suction-stop chamber is provided with a suction-stop extraction chamber inside, and a suction-stop bead 222 is movably arranged in the suction-stop extraction chamber. Several sets of liquid injection holes 223 are provided through the suction-stop chamber, and the liquid injection holes 223 are connected to the negative pressure pumping chamber and the suction-stop extraction chamber. When a positive pressure is formed in the negative pressure pumping chamber, the extrusion member 213 descends in the negative pressure pumping chamber, and the suction stop bead 222 descends to the bottom of the suction stop extraction chamber to close the extraction part 23. When a negative pressure is formed in the negative pressure pumping chamber, the extrusion member 213 rises in the negative pressure pumping chamber, and the suction stop bead 222 rises to the top of the suction stop extraction chamber, so that the liquid enters the negative pressure pumping chamber through the liquid injection hole 223 along the extraction part 23.

[0027] Furthermore, a second limiting block 224 is provided at the top of the suction chamber corresponding to the extrusion member 213, and the other end of the spring 221 is sleeved on the suction chamber to achieve positioning, on the one hand to prevent the extrusion member 213 from descending excessively, and on the other hand to improve the directional compression and reset of the spring 221; A second sealing docking seat is provided extending from the bottom of the suction stop chamber. The extraction part 23 is inserted into the second sealing docking seat so that the extraction part 23 and the suction stop extraction cavity are connected, thereby improving the assembly sealing and reliability between the extraction part 23 and the pumping part 22.

[0028] Furthermore, a third limiting block 215 is provided at the upper end of the pump rod 212 corresponding to the first sealing cover 3. The distance between the third limiting block and the adjacent metering point 214 is equal to the distance between the adjacent metering points 214. This avoids excessive pressing of the pressing head 211 and increases the pressing stroke of the pump rod 212.

[0029] Preferably, each of the liquid storage chambers is hinged with a set of liquid filling caps 5; by opening the liquid filling caps 5, the required liquid is added to the liquid storage chamber; The liquid storage chamber is a transparent tank, and the surface of the liquid storage chamber is provided with a capacity scale 6.
