[0016] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0017] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0018] Any feature disclosed in this specification (including any appended claims, abstract, and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. In other words, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0019] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model is an automatic laboratory glassware cleaning device, comprising a horizontal tube 1, on which a plurality of vertical tubes 2 are installed, and a drain pipe 3 is movably installed at one end of the vertical tube 2 away from the horizontal tube 1, and a nozzle 4 is installed at the other end of the drain pipe 3, and the outside of the drain pipe 3 is annularly structured and equipped with a plurality of inclined rods 7, and the inclined rod 7 is expanded at one end away from the drain pipe 3 to form a mounting portion 12, and a first ball groove is provided on the outer end surface of the mounting portion 12, and a second ball groove is provided on the top surface of the mounting portion 12, and a first ball 13 is movably installed in the first ball groove, and a second ball 14 is movably installed in the second ball groove, and a driving mechanism for driving the drain pipe 3, the nozzle 4 and the inclined rod 7 to rotate is installed on one side of the drain pipe 3.

[0020] In this embodiment, the driving mechanism includes a rack 6, a cylinder 10, a positioning column 11 and multiple gears 5. The gears 5 are all installed on the drain pipe 3. The racks 6 are all arranged on one side of the drain pipe 3 and are all meshed and connected with the gears 5. A support frame 8 is installed on the outside of the cross pipe 1. The cylinder 10 is installed at one end of the support frame 8. The piston rod of the cylinder 10 passes through the support frame 8 and is fixedly connected to one end of the rack 6. The other end of the rack 6 is provided with a positioning hole. One end of the positioning column 11 is inserted into the positioning hole, and the other end is installed on the inner side of the support frame 8. The stability of the rack is increased by the positioning hole and the positioning column, so that the rack can only move back and forth horizontally along the positioning column, avoiding tilting toward one end.

[0021] In this embodiment, a liquid inlet pipe 9 is installed at one end of the horizontal pipe 1.

[0022] In this embodiment, the tilting rod 7 and the drain pipe 3 are fixedly connected by a hinge, and the hinge is a torsion spring hinge. The tilting rod can be automatically opened outward by twisting the torsion spring hinge, so that the tilting rod can support glassware with different inner diameters outward, thereby increasing adaptability.

[0023] In this embodiment, a positioning groove with an annular structure is provided on the inner wall surface of the opening of the vertical pipe 2, and a positioning ring is installed on one end of the drain pipe 3 located inside the vertical pipe 2. The positioning ring is movably arranged in the positioning groove, so that the drain pipe can only rotate with the positioning groove as the center, thereby preventing the drain pipe from directly detaching from the vertical pipe.

[0024] When in use, the tilt rod is squeezed inwards to move it inwards, so that the glass vessel can be placed outside the drain pipe. After releasing the tilt rod, the tilt rod is automatically opened outwards by twisting the torsion spring hinge, so that the first ball contacts the inner surface of the glass vessel and the second ball contacts the top surface of the inner cavity of the glass vessel. The glass vessel can be suspended in the air by the second ball, so that the opening of the glass vessel is always in an open state.

[0025] When in use, a hose can be prepared, one end of the hose is connected to the liquid inlet pipe, and the other end is connected to an external water source (such as a faucet, a water pump, etc.). The external water source can enter the horizontal pipe along the hose until it is sprayed out from the nozzle through the vertical pipe and the drain pipe. The sprayed water can flush the inner wall of the glassware to complete the cleaning of the glassware. During the cleaning process, the cylinder can be started to make the piston rod of the cylinder continuously extend and retract back and forth. The extension and retraction of the piston rod drives the rack, and the movement of the rack drives the gear and the drain pipe, and the drain pipe synchronously drives the tilting rod. During the rotation of the tilting rod, since the tilting rod contacts the glassware through the first sphere and the second sphere, the friction between the tilting rod and the glassware is small, so the tilting rod can rotate inside the glassware, avoiding the tilting rod always staying in one position and blocking the inner wall of the glassware, so as to ensure comprehensive cleaning.

[0026] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
