Description

Flow path structure of liquid pump

The invention relates to a liquid extractor for extracting liquid from a container, and in particular to a liquid extractor equipped with an air intake adjustment structure, so as to improve the air flow and extract the liquid more smoothly.

Expert wine tasters need to go through the "decanting" step before drinking red wine. The so-called decanting is to allow the red wine to come into contact with air to produce chemical changes. As the area and time of contact between the red wine and oxygen increase, the aroma of the wine blooms faster and the tannins soften, creating a smoother taste.

In addition, some drinks and other liquids can also enhance the flavor by increasing the amount of dissolved oxygen after mixing with air. In the early days, the way to decant red wine was to pour the wine into a glass and leave it for a while to be exposed to air. However, because it took a long time, liquid extractors (or decanters) that can extract liquid and mix with air were later commercially available, and various structural versions have been developed. The latest structural version of the liquid extractor is used to be configured at the mouth of the container. The method of use is to use an electric pump to extract the liquid in the container out of the container and into the extractor body, and to introduce external air into the body through the air intake structure set in the body to mix with the liquid, so that the liquid is quickly mixed with oxygen in the air, thereby achieving the effect of quickly decanting or mixing with air to enhance the flavor of the drink.

Specifically, the known liquid extractor includes a body, an air inlet, a liquid drawer and a liquid outlet, wherein the liquid drawer is used to draw liquid from a container into the body; the air inlet introduces external air into the body to mix the drawn liquid, and then the liquid mixed with air flows out through the liquid outlet. In order to control the amount of mixed air according to the needs of different liquids, the known liquid extractor designs the air inlet as a structure with adjustable air flow; the liquid drawer has an air flow channel structure for air convection; and the liquid outlet has a structure for sealing the liquid outlet pipe and the liquid outlet of the body. However, the structures of the air intake part, the liquid suction part and the liquid discharge part of the conventional liquid extractor are relatively complicated, and the structure for providing air convection cannot be guaranteed to be completely smooth, thereby affecting the smoothness of the extracted liquid.

Specifically, the air intake portion 20 includes a valve body 201, a valve rod 202, a fixing seat 203, a spring 204, a cap 205, a knob 206 and a fixing element 207; wherein the valve body 201 is used to be assembled into the main body 10 so that the air intake valve hole 2011 formed in the valve body 201 and the air intake port 1023 of the main body 10 are correspondingly connected, and screw holes 2012 are respectively provided on two opposite sides of the valve body 201. One end of the valve stem 202 has an enlarged valve head 2021, and the front end of the valve head 2021 is axially extended to form a needle valve 2023. The valve head 2021 can be movably matched with the valve body 201, so that the needle valve 2023 can be correspondingly inserted into the intake valve hole 2011. By controlling the axial movement of the valve stem 202, the size of the intake valve hole 2011 blocked by the needle valve 2023 can be controlled, thereby controlling the air flow through the intake valve hole 2011. In a preferred embodiment of the present invention, a protrusion 2022 is provided on the side of the valve head 2021, and a step portion 2013 is formed on the end edge of the valve body 201 next to the intake valve hole 2011. Accordingly, when the valve head 2021 is engaged with the valve body 201, the protrusion 2022 contacts the step portion 2013, so that when the valve stem 202 is rotated, the protrusion 2022 moves along the step portion 2013 to gradually control the degree to which the intake valve hole 2011 is blocked by the needle valve 2023, that is, to control the opening size of the intake valve hole 2011 to control the amount of air intake.

In order to rotatably position the valve rod 202 on the valve body 201, the invention further sets the spring 204 on the valve rod 202, and then passes the valve rod 202 through the central through hole 2031 of the fixing seat 203, and then passes the fixing element 207 through the holes 2032 on both sides of the fixing seat 203 and locks into the screw hole 2012 of the valve body 201, so that the opposite sides of the spring 204 are pressed against the valve head 2021 and the fixing seat 203, so that the valve rod 202 can move elastically in the axial direction, and according to This allows the valve stem 202 to be rotatably restricted between the valve body 201 and the fixed seat 203. After the valve stem 202 passes through the through hole of the cap 205, the knob 206 is assembled to the end of the valve stem 202. Therefore, the valve stem 202 can be rotated by rotating the knob 206, thereby controlling the size of the needle valve 2023 blocking the intake valve hole 2011 and controlling the air intake amount. Among them, the preferred embodiment of the fixing element 207 can be a bolt. In addition, an indicator mark (not shown in the figure) can be set on the outer side end face of the knob 206. When the knob 206 is rotated, the opening size of the intake valve hole 2011 of the valve stem 202 can be understood by the angle pointed by the indicator mark.

The connecting seat 301 is connected to the lower end of the main body 10 by a spiral locking method, that is, the lower end edge of the main body 10 is inserted into the concave edge 3011 formed at the upper end of the connecting seat 301 due to the spiral, so as to serve as an element for covering the container mouth when the liquid extractor of the present invention is connected to the container 60. The bottom surface of the connecting seat 301 is formed with a plurality of convex ribs 3012 that are preferably arranged radially.

The mounting sleeve 302 is an element for being arranged between the main body 10 and the connecting seat 301 so as to be inserted into the opening of the container 60; the mounting sleeve 302 includes a cylinder 3021 having a center hole 3025, a flange 3026 is formed at one end of the cylinder 3021, a plurality of soft fins 3022 are formed on the outer surface of the cylinder 3021, and a side wall of the cylinder 3021 is formed with at least one airflow hole 3024 that passes through the center hole 3025 and the outside of the side wall. The airflow holes 3024 preferably have a plurality of holes and are arranged in a circle around the extension tube 103. At least one interruption is formed at the same position of each of the winglets 3022, and the interruptions are formed into grooves 3023 along the longitudinal direction; for example, the grooves 3023 are formed by axially extending and cutting the winglets 3022, so that the winglets 3022 form a discontinuous ring shape around the outer surface of the cylinder 3021.

The liquid drawing tube 303 is a component for connecting one end thereof to the mounting sleeve 302 and for drawing liquid; specifically, a connector 3031 is provided at one end of the liquid drawing tube 303, and the connector 3031 is screwed to the lower end of the mounting sleeve 302 and connected to the central hole 3025, and enables the interior of the body 10 to be connected to the outside through the airflow hole 3024 and the airflow channel 1031.

Figures 2 to 4 also show the structure of the liquid outlet 40, including: a tube seat 401, a liquid outlet tube 402 and an O-ring 403; wherein, the first end of the tube seat 401 is formed with an external thread 4011, and after the liquid inlet end of the liquid outlet tube 402 passes through the tube seat hole of the tube seat 401, the O-ring 403 is arranged at the liquid inlet end, and then the liquid inlet end is inserted into the liquid outlet port 1022 of the body 10, that is, the O-ring 403 is arranged between the liquid inlet end of the liquid outlet tube 402 and the liquid outlet port 1022, and then the tube seat 401 is screwed into the internal thread formed on the liquid outlet end of the body 10 through the external thread 4011, and the O-ring 403 is pressed by the first end of the tube seat 401 to form a tight fit.

As shown in FIGS. 3 to 5 , when the liquid extractor of the present invention is in operation, the liquid extracting tube 303 of the liquid extracting part 30 is first inserted into the container 60 (e.g., a wine bottle), and then the button 502 of the control unit 50 is operated to start the pumping action, thereby extracting the liquid in the container 60 through the liquid extracting tube 303 to flow out through the liquid flow path 102 and the liquid outlet tube 402. During this process, the knob 206 can be appropriately rotated to adjust the opening size of the air inlet valve hole 2011 of the valve body 201. Accordingly, according to the Pernickety law, when the liquid passes through the liquid flow path 102 quickly, a negative pressure will be formed at the air inlet valve hole 2011, thereby introducing external air into the liquid flow path 102 through the air inlet valve hole 2011 to mix with the liquid, and the liquid mixed with the air then flows out from the liquid outlet tube 402. At the same time, external air can smoothly pass through the air flow hole 3024 and the air flow channel 1031 into the air container 60 to generate convection (as shown by the dotted lines in Figures 4 and 5), so that the liquid can be smoothly extracted inside and outside the container 60 due to the smooth air convection.

This invention uses the aforementioned flow path structure to not only simplify the structure of the liquid extractor equipped with an air intake adjustment structure, but also make the airflow introduced into the air smoother, so that the liquid can be extracted more smoothly and the practicality is better.

The above-mentioned embodiments only represent the preferred implementation of the present invention, and the description is relatively specific and detailed, but it should not be understood as limiting the patent scope of the present invention. It should be pointed out that ordinary technicians in this field can make several changes and improvements without departing from the concept of the present invention, which are all within the protection scope of the present invention.
