Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] refer to Figure 1The liquid extraction device 100 includes a container 1, a suction tube 2, a liquid level sensor 3, and a clamp 4. The container 1 is filled with liquid and has an opening 1a at its top. The suction tube 2 extends into the container 1 through the opening 1a to extract the liquid from the container 1 to other equipment. The liquid level sensor 3 extends into the container 1 through the opening 1a to detect whether the liquid in the container 1 has been completely extracted. The clamp 4 is fitted to the opening 1a and fixes the suction tube 2 and the liquid level sensor 3 together. When the liquid level sensor 3 detects that the liquid in the container 1 has been completely extracted, the suction tube 2 and the liquid level sensor 3 can be removed from the container 1 simultaneously by holding the clamp 4. After the container 1 is refilled with cleaning agent or wetting agent, the suction tube 2 and the liquid level sensor 3 can be reinstalled by holding the clamp 4. Alternatively, the suction tube 2 and the liquid level sensor 3 can be simultaneously inserted into another container 1 containing liquid by holding the clamp 4 to continue liquid extraction.

[0020] refer to Figure 1 Container 1 can be used to fill cleaning agents or wetting agents. Liquid is drawn out of container 1 through suction tube 2, and then the outlet of suction tube 2 is connected to other liquid inlet pipes in the vacuum boiling cleaner through sleeve 2b, so as to draw the liquid to other devices (such as the cleaning chamber) in the vacuum boiling cleaner for cleaning items placed in the vacuum boiling cleaner. Container 1 can also be filled with water or other liquids, and the liquid can be drawn to other laboratory or industrial equipment using suction tube 2. This is not a limitation in the embodiments of this utility model.

[0021] When filling container 1 with liquid, avoid overfilling to prevent overflow when the suction tube 2 and liquid level sensor 3 are inserted into container 1. A perforated handle 1b is provided on one side of the top of container 1 for easy transfer, and a circular opening 1a is provided on the other side. The suction tube 2 and liquid level sensor enter and are installed inside container 1 through the circular opening in the center of this opening 1a. A container box 8 is provided outside container 1, which is cubic in shape with one side being an open surface. Two parallel slide rails 9 are installed on both sides of the bottom of container box 8, extending outwards along the bottom of container box 8 towards the open side. Between the two slide rails 9 is a platform 10 that slides with the slide rails 9. Two identical containers 1 are placed side-by-side on the upper surface of this platform 10, with the overall dimensions of the two containers 1 slightly smaller than those of container box 8. After the container 1 containing liquid is placed on the platform 10 via the handle 1b, the container 1 can be pushed into the container box 8 from the outside using the slide rail 9. Alternatively, after the liquid in the container 1 has been completely drawn out, the container 1 can be pulled out of the container box 8 using the slide rail 9. The size of the container box 8 can be designed according to the specific size of the container 1, and one or more containers 1 can be placed inside as needed. This embodiment of the present invention does not impose any limitations on this.

[0022] refer to Figure 1The suction tube 2 is a long, thin cylindrical tube. Its portion inside the container 1 is a straight cylindrical tube, vertically inserted into the container 1 through the opening 1a. The bottom of the suction tube 2 is the liquid inlet, through which liquid in the container 1 is drawn to other equipment. The length of the suction tube 2 inside the container 1 is the same as the distance from the bottom of the container 1's inner cavity to the bottom of the opening 1a, allowing the liquid inlet of the suction tube 2 to extend from the opening 1a to the bottom of the container 1's inner cavity, thus extracting as much liquid as possible and minimizing liquid residue at the bottom of the container 1's inner cavity. The suction tube 2 has a bent portion 2a outside the container 1. By bending the suction tube 2 vertically to 90°, the liquid outlet of the suction tube 2 faces horizontally towards the inside of the container box 8's opening. This design facilitates pushing the liquid extraction device 100 into the container box 8, resulting in a more compact internal structure. Depending on the actual usage environment and equipment requirements, the suction tube 2 may not be bent, or the bending angle may be less than 90°. The direction of the liquid outlet can also be set according to the actual usage environment. This utility model does not impose any restrictions on this aspect. (Reference) Figure 1 The liquid level sensor 3 includes a slender, straight rod 3a. The overall length of the rod 3a, after being connected to the float portion of the liquid level sensor 3, is slightly greater than the distance from the bottom of the inner cavity of the container 1 to the top of the opening 1a. The liquid level sensor 3 is inserted into the inner cavity of the container 1 through the opening 1a, ensuring that the bottom of the liquid level sensor 3 contacts the inner wall of the bottom of the container 1. This prevents liquid waste caused by some remaining liquid at the bottom of the inner cavity of the container 1 when the liquid level sensor 3 detects insufficient liquid and the container 1 needs to be replaced. Commonly used liquid level sensors 3 include single-flange hydrostatic / double-flange differential pressure liquid level sensors, magnetic liquid level sensors, submersible liquid level sensors, electric internal float liquid level sensors, electric float liquid level sensors, capacitive liquid level sensors, magnetostrictive liquid level sensors, servo liquid level sensors, ultrasonic liquid level sensors, and radar liquid level sensors, etc. In this embodiment, the liquid in contact with the level sensor 3 is mainly a cleaning agent or a wetting agent. Based on the size and structure of the level sensor 3, as well as the economy, durability and detection stability in actual use, it is more preferable that a float-type level sensor is selected as the level sensor 3 in this embodiment.

[0023] refer to Figure 1 and 2The clamp 4 is fitted onto the opening 1a of the container 1. The clamp 4 secures the suction tube 2 and the liquid level sensor 3 together. When the liquid in the container 1 is insufficient, the suction tube 2 and the liquid level sensor 3 can be simultaneously removed from the container 1 using the clamp 4, and then simultaneously installed into a container 1 filled with liquid, or the container 1 can be filled with liquid and then returned. The clamp 4 includes a first clamping member 4a and a second clamping member 4b. The first clamping member 4a and the second clamping member 4b have the same cross-sectional shape (semi-circular). The semi-circular first clamping member 4a and the second clamping member 4b are joined together radially to form a clamp 4 with a circular cross-section. The diameter of this circle is equal to the chord length of the semi-circular cross-section of the first clamping member 4a or the second clamping member 4b. In the axial direction of the clamp 4, the clamp 4 includes a flared section 6a with a larger diameter and a narrow section 6b with a smaller diameter. A screw hole 7 is provided at the horizontal center of the flared section 6a. The extension direction of the screw hole 7 is perpendicular to the mating surface of the first clamping member 4a and the second clamping member 4b. The first clamping member 4a and the second clamping member 4b are connected by a screw thread that extends radially and passes through the center of a semi-circle. The first clamping member 4a and the second clamping member 4b are provided with a first groove 5a and a second groove 5b at their mating surfaces. The first groove 5a and the second groove 5b are both cylindrical. The inner diameter of the first groove 5a is the same as the outer diameter of the inner cavity of the suction tube 2 in the container 1, allowing the suction tube 2 to pass through the clamp 4 and enter the container 1. The inner diameter of the second groove 5b is the same as the outer diameter of the rod 3a of the liquid level sensor 3, allowing the rod 3a of the liquid level sensor 3 to pass through the clamp 4 and enter the container 1. After the suction tube 2 and the rod 3a pass through the first groove 5a and the second groove 5b of the clamp 4, respectively, adjust the plane of the liquid inlet of the suction tube 2 to be as flat as possible with the bottom end of the liquid level sensor 3, and make the bottom end of the liquid level sensor 3 and the liquid inlet of the suction tube 2 extend simultaneously along the opening 1a to the same position at the bottom of the inner cavity of the container 1. (Reference) Figure 1 The outer diameter of the narrow section 6b of clamp 4 is the same as the inner diameter of the circular opening in the center of opening 1a, allowing the narrow section 6b of clamp 4 to be inserted into opening 1a of container 1, with the vertical outer wall of the narrow section 6b fitting against the inner wall of opening 1a. The radial diameter of the flared section 6a is larger than the inner diameter of opening 1a, preventing it from entering opening 1a. By having the lower surface of the flared section 6a contact the upper surface of opening 1a and the arc-shaped outer wall of the narrow section 6b fit tightly against the inner wall of opening 1a, clamp 4 is fixed to container 1, and suction pipe 2 and liquid level sensor 3 are quickly installed into container 1.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
