Description

Technical Field

[0001] The present invention relates to the technical field of bottle - mouth liquid dispensers, and more specifically, to a bottle - mouth liquid dispenser. Background Art

[0002] In some laboratories, when preparing solutions, it is necessary to transfer liquid reagents from one reagent bottle to another through pipettes or other liquid - taking methods. Many acid, base, and salt solutions are highly corrosive and toxic. For safety reasons, the pouring method cannot be used for liquid separation. At this time, a liquid dispenser must be used. Most existing bottle - mouth liquid dispensers squeeze the gas in the bottle body through a pneumatic mechanism on the bottle stopper, so that the gas presses the liquid in the bottle body out of the liquid - separating tube. The existing bottle - mouth liquid dispensers still have the following problems: (1) When the liquid - taking is completed, some of the excess reagents in the bottle - mouth liquid dispenser are not easy to recycle; (2) It is not easy to control the liquid - taking volume; (3) The existing bottle - mouth liquid dispenser is assembled by splicing glass and multiple plastic parts. The plastic parts are injection - molded by a mold, with complex material processes and high environmental requirements, and there is an easy liquid leakage phenomenon at the splicing points.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0026] Such as Figures 1-5As shown in the figure, a bottle mouth dispenser is disclosed according to the present invention, which includes a dispenser cylinder body made of transparent glass. The dispenser cylinder body is an integrated structure integrating a reflux valve body 110. One side of the upper end of the reflux valve body 110 is connected to an infusion cylinder body 130 through a first infusion tube 120, and the other side is connected to a second infusion tube 140. The lower end of the reflux valve body 110 is connected to a liquid return tube 150. A reflux valve switch 200 is installed in the valve cavity of the reflux valve body 110. A guiding through hole 210 for communicating the first infusion tube 120 and the second infusion tube 140 is opened on the reflux valve switch 200. A reflux groove 220 for communicating the first infusion tube 120 and the liquid return tube 150 is also opened on the reflux valve switch 200. The lower end of the infusion cylinder body 130 is connected to a liquid inlet valve group. A piston 131 is provided in the upper cavity of the infusion cylinder body 130. A scale is provided on the outer wall of the upper cavity of the infusion cylinder body 130. The second infusion tube 140 is connected to a liquid outlet tube 300 through a liquid outlet valve group.

[0027] Embodiment 1:

[0028] The dispenser cylinder body in this application includes a reflux valve body 110, a first infusion tube 120, an infusion cylinder body 130, a second infusion tube 140, and a liquid return tube 150, and is an integrated structure made of transparent glass, which effectively improves high-temperature disinfection and extends the service life of the product, and solves the problem of dripping and leaking after splicing the glass cylinder and plastic parts, improving the quality and working efficiency.

[0029] Embodiment 2:

[0030] The liquid inlet valve group is threadedly connected to the lower end of the infusion cylinder body 130 through the first threaded part, and is sealed by pressing the O-ring 440 inside. This connection method facilitates the disassembly and replacement of the liquid inlet valve group. The liquid inlet valve group extends into the solution to be taken through a conduit. When the piston 131 is lifted upward, under the suction force, the first valve ball 450 is separated from the first valve seat 420, and the solution is sucked into the cavity at the upper end of the infusion cylinder body 130. By adjusting the position of the flow-through hole 210 through the handle 230, the first infusion tube 120 and the second infusion tube 140 are made conductive. At this time, when the piston 131 is pressed down, the solution in the upper cavity of the infusion cylinder body 130 is pressured and flows from the first infusion tube 120 through the flow-through hole 210 into the second infusion tube 140. Subsequently, the solution pushes the second valve ball 530 through the channel in the center of the second valve seat 540, separating the second valve seat 540 from the second valve ball 530, then the inner channel of the liquid outlet valve group is made conductive, and the solution enters the liquid outlet tube 300 from the liquid outlet valve group and finally enters the liquid-taking container from the liquid outlet tube 300. During the process of moving the piston 131, it is identified through the scale on the outer wall of the upper cavity of the infusion cylinder body 130, so as to control the liquid suction volume and the infusion volume. The liquid outlet valve group is threadedly connected to the second infusion tube 140 through the second threaded connection part, and the O-ring 550 on the second threaded connection part presses against the inside of the second infusion tube 140 for sealing. The liquid outlet valve group is threadedly connected to the liquid outlet tube 300 through the third threaded connection part, and this connection method facilitates the disassembly and replacement of the liquid outlet valve group.

[0031] Embodiment 3:

[0032] After the liquid taking is completed, by adjusting the position of the reflux groove 220 through the handle 230, the first infusion tube 120 and the liquid return tube 150 are made conductive, and the piston 131 is pushed. Then the excess liquid in the upper cavity of the infusion cylinder body 130 flows from the first infusion tube 120 through the reflux groove 220 into the liquid return tube 150, and finally the excess solution is refluxed to the container storing the solution through the liquid return tube 150. The valve cavity of the reflux valve body 110 is a conical structure, which is convenient for the reflux of the liquid. The reflux valve switch 200 is locked through the first spring 240 and the lock nut 250.

[0033] Embodiment 4:

[0034] Before using the bottle mouth dispenser of the present application, the liquid inlet valve group can be unscrewed, the liquid outlet valve group can be unscrewed, the lock nut 250 can be unscrewed to disassemble the reflux valve switch 200, and the piston 131 can be removed, then the entire dispenser cylinder body can be disinfected at high temperature.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
