Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine preparation technology, and in particular to a liquid dispensing device with the function of excreting residues. Background Technology

[0002] The applicant previously disclosed a draining device installed at the bottom of a tank (a medicine tank used for preparing supernatant of traditional Chinese medicine). The draining device is equipped with a telescopic tube assembly. The inner telescopic tube of the telescopic tube assembly is used to supply cleaning fluid into the tank and to draw out supernatant or discharge waste liquid from the tank. In the process of drawing out supernatant, by keeping the upper end of the inner telescopic tube near the liquid surface in the tank, the quality of the drawn supernatant can be improved.

[0003] To ensure the cleaning fluid effectively cleans the inner wall of the tank, a spraying device, such as a spray ball, needs to be installed at the upper end of the inner telescopic tube of the telescopic tube assembly. This spraying device is significantly larger than the telescopic tube assembly. To allow the spraying device to enter the tank, the installation port at the bottom of the tank needs to be larger than the radial dimension of the spraying device. This results in an annular gap between the telescopic tube of the telescopic tube assembly and the installation port. In the later stages of wastewater discharge, wastewater mixed with residue will remain in the annular gap, leading to incomplete wastewater discharge. Utility Model Content

[0004] In view of the above-mentioned technical problems existing in the prior art, the embodiments of this utility model provide a liquid supply and drainage device with the function of excreting residues.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in the embodiments of this utility model is as follows:

[0006] A liquid dispensing device with residue excretion function is used to be installed at the bottom of a medicine tank. The liquid dispensing device with residue excretion function includes:

[0007] A telescopic tube assembly includes a fixed tube located on the outer side and at least one telescopic tube located on the inner side of the fixed tube. A spraying device is installed at the upper end of the telescopic tube. The telescopic tube and the spraying device enter the medicine tank through a mounting hole opened at the bottom of the medicine tank.

[0008] A chuck, fixed to the upper end of the fixed tube of the telescopic tube assembly, is screwed and fixed to the mounting plane at the bottom of the medicine container, and the mounting hole penetrates the mounting plane; wherein:

[0009] The upper surface of the chuck is provided with an annular guide groove in the area corresponding to the mounting hole. The bottom of the annular guide groove is inclined, thereby defining the high side and the low side.

[0010] A discharge channel extends from the lower side and extends to the outer peripheral surface of the chuck.

[0011] Preferably, the cross-section of the annular guide groove is trapezoidal or rectangular.

[0012] Preferably, the discharge channel includes an axial channel and a radial channel that intersect each other. The axial channel extends to the lower side of the annular guide groove, and the radial channel extends to the outer peripheral surface of the chuck to form an interface. A discharge connector is installed at the interface.

[0013] Preferably, the telescopic tube includes an inner telescopic tube and an intermediate telescopic tube.

[0014] Preferably, the spraying device is a spray ball.

[0015] Preferably, the telescopic tube assembly is a pneumatic telescopic tube assembly.

[0016] Preferably, a sealing gasket is provided between the chuck and the mounting surface.

[0017] Compared with the prior art, the beneficial effects of the liquid supply and drainage device with residual excretion function disclosed in this utility model are:

[0018] In the later stage of draining the waste liquid in the medicine tank, the waste liquid containing residue in the annular gap between the mounting hole and the inner telescopic tube can be discharged through the drain channel. When the waste liquid approaches the upper plate surface of the chuck, the bottom of the tank is configured as an inclined annular guide groove to drain the waste liquid on the chuck as much as possible.

[0026] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0027] like Figure 1 and Figure 2 As shown, an embodiment of this utility model discloses a liquid dispensing device with the function of excreting residue. The liquid dispensing device is used to install on the bottom of the medicine tank 30. The bottom of the medicine tank 30 is provided with a mounting hole 31, and a flat mounting surface is machined around the mounting hole 31.

[0028] The liquid supply and drainage device includes: a telescopic tube assembly 10, a chuck 14, and a spray ball 15; the telescopic tube assembly 10 includes a fixed tube 11, an intermediate telescopic tube 12 located inside the fixed tube 11, and an inner telescopic tube 13 located inside the intermediate telescopic tube 12. The intermediate telescopic tube 12 and the inner telescopic tube 13 are telescopic by means of pneumatic principle. The spray ball 15 is installed at the upper end of the inner telescopic tube 13. By providing cleaning fluid to the lower end of the inner telescopic tube 13, the spray ball 15 sprays cleaning fluid onto the inner wall of the medicine tank 30 through the inner telescopic tube 13.

A sealing ring is installed between the chuck 14 and the mounting surface to prevent liquid leakage from the medicine tank 30. In this way, the intermediate telescopic tube 12, the inner telescopic tube 13, and the spray ball 15 enter the medicine tank 30 through the mounting hole 31.

[0030] An annular guide groove 21 is provided on the upper surface 141 of the chuck 14, corresponding to the mounting hole 31. The bottom of the annular guide groove 21 is machined into a slope, so that the bottom of the annular guide groove 21 has a low side 212 and a high side 211. A discharge channel 22 is constructed between the low groove of the annular guide groove 21 and the outer peripheral surface of the chuck 14. The discharge channel 22 may include an axial channel 221 extending axially from the low side 212 and a radial channel 222 extending radially from the axial channel 221 to the outer peripheral surface to form an interface. A discharge connector 23 is screwed into the interface, and the discharge pipe is connected to the discharge connector 23. In the later stage of draining the waste liquid in the medicine tank 30, the waste liquid containing residue in the annular gap between the mounting hole 31 and the inner telescopic tube 13 can be discharged through the drain channel 22. When the waste liquid approaches the upper plate surface 141 of the chuck 14, the bottom of the tank is configured as an inclined annular guide groove 21 to drain the waste liquid on the chuck 14 as much as possible.
