[0035] Example

[0036] This embodiment provides a liquid discharge component, such as Figure 1 As shown, the liquid discharge assembly includes a holding pool 1, a blocking member 2, a liquid discharge pipe 4 and a first switch member 6. The holding pool 1 is suitable for containing cleaning liquid, and the first switch member 6 is installed on the liquid discharge pipe 4. The upper end of the holding pool 1 is provided with an opening side, which is used for discharging cleaning liquid and taking and placing containers; one end of the liquid discharge pipe 4 is connected to the medium channel, and the other end of the liquid discharge pipe 4 is suitable for communicating with an external liquid collection device, which is used to collect the cleaning liquid after cleaning the container.

[0037] In this embodiment, if Figures 1 to 3As shown, a medium outlet 12 is provided on the bottom wall side of the containing pool 1, a stepped groove structure 11 is constructed at the medium outlet 12, a medium channel is provided on the inner side of the stepped groove structure 11, and the medium channel and the medium outlet 12 are connected; in the specific implementation process, the stepped groove structure 11 is used to support the sealing member 2, and the sealing member 2 is suitable for being abutted against the stepped groove structure 11 to block the connection between the medium outlet 12 and the medium channel.

[0038] In a specific embodiment, the stepped groove structure 11 is provided with one or more stop surfaces, and at least one stop surface is configured to abut against the blocking member 2 .

[0039] As an exemplary embodiment, the stepped groove structure 11 is provided with three layers of gradient, specifically, as Figure 2 and Figure 4 As shown, the stepped groove structure 11 is provided with a first stop surface 111 , a second stop surface 112 and a third stop surface 113 in sequence from top to bottom along the height direction, wherein the first stop surface 111 and the blocking member 2 are arranged in contact with each other.

[0040] In some embodiments, the blocking member 2 includes a blocking body 21 and a handle portion 22 that are fixedly connected. Figure 1 and Figure 5 As shown, the blocking body 21 is disposed in abutment with the inner wall of the medium channel, the handle portion 22 is disposed on a side of the blocking body 21 away from the medium channel, and the first stop surface 111 is disposed in abutment with the blocking body 21 .

[0041] As a variation, a stepped protrusion structure is provided on the outer peripheral side of the plugging body 21, and two or more stop surfaces abut against the plugging body 21 to limit the position, for example, the stepped protrusion structure and the first stop surface 111 and the second stop surface 112 are respectively abutted and configured in a conformal manner. In this way, the plugging body 21 and the stepped groove structure 11 are tightly connected, which can increase the flow resistance to the downward penetration of the cleaning liquid, and is conducive to delaying the gradual downward penetration of the cleaning liquid. Of course, the stepped protrusion structure can be abutted against more stop surfaces.

[0042] The receiving pool 1 includes a basin body and a guide body connected to each other. In a specific embodiment, the basin body and the guide body are welded or manufactured in an integrated manner. When the plugging member 2 closes the receiving pool 1, a cleaning liquid is placed on the basin body. When the plugging member 2 opens the receiving pool 1, the basin body and the guide body are connected to drain the liquid.

[0043] As a further embodiment, Figure 1As shown, the drainage assembly also includes a filter 3, which is arranged in the medium channel, and the filter 3 is arranged below the plugging member 2. There are at least two stop surfaces, and any two stop surfaces are staggered in the height direction, one of which is located at the upper end and is arranged in abutment with the plugging member 2, and the other stop surface located at the lower end is suitable for supporting and hanging the filter 3. Taking the step groove structure 11 as an example, the first stop surface 111 is arranged in abutment with the plugging member 2, and the upper end of the filter 3 is arranged in abutment with the second stop surface 112 or the third stop surface 113; when the plugging member 2 is removed to open the connection between the medium channel and the medium outlet 12, the cleaning liquid in the holding pool 1 flows through the filter 3 and is discharged to the drainage pipe 4 on the downstream side, and the filter 3 serves the purpose of filtering the outflowing cleaning liquid. At the same time, the filter 3 is arranged, which is conducive to increasing the flow resistance of the cleaning liquid discharge, reducing the drainage flow rate, and improving the stability of the drainage assembly.

[0044] As a preferred embodiment, the stepped groove structure 11 is configured as a rotating body structure, the medium outlet 12 is configured as a circular structure, the stepped groove structure 11 and the medium outlet 12 are configured coaxially, and the first stop surface 111, the second stop surface 112 and the third stop surface 113 are configured as annular surfaces.

[0045] In a specific embodiment, the inner diameters of the first stop surface 111, the second stop surface 112 and the third stop surface 113 are arranged to decrease. From the first stop surface 111 to the third stop surface 113, the height of the stop surface decreases, and the inner diameter of the inner side of the stop surface shrinks and decreases accordingly.

[0046] In a specific embodiment, the stop surface can be set to be horizontally distributed, the sealing body 21 of the sealing member 2 is set to a rotating body structure, and the step groove structure 11 can be configured with a circumferential limiting inner end face to abut the circumferential outer end face of the sealing body 21, and the limiting inner end face can be arranged vertically.

[0047] In some embodiments, Figure 1 As shown, the liquid discharge assembly further includes an adapter 5, one side of which is sealed and connected to the liquid outlet of the containing tank 1, and the other side of which is sealed and connected to the liquid inlet side of the liquid discharge pipe 4. The adapter 5 can be a quick-release connector, such as a TC50 chuck, which is easy to connect and operate, and is convenient for the assembly and implementation of the liquid discharge assembly.

[0048] As a further embodiment, the drain assembly further includes a second switch 7, which is mounted on the adapter 5. The second switch 7 can be provided with a leak-proof design behind the plugging member 2 to improve the drain assembly's ability to prevent the cleaning liquid from penetrating, and also facilitate the unified discharge of the solution. In a specific embodiment, the second switch 7 can be a manual valve.

[0049] In some embodiments, the drain pipe 4 may be configured as an alkali-resistant flexible pipe body.

[0050] In a specific embodiment, at least part of the drain pipe 4 is configured as a U-shaped pipe structure. Specifically, the drain pipe 4 can be configured as a pipe body structure that is a combination of a U-shaped pipe structure and a straight pipe structure; of course, the drain pipe 4 can be configured as a U-shaped pipe structure as a whole. The U-shaped pipe structure can be disposed on the upstream side of the first switch member 6. The use of the U-shaped pipe structure is conducive to intercepting the cleaning liquid discharged from the holding tank 1, and when the blocking member 2 blocks the sealing medium channel, it is conducive to establishing a pressure environment that blocks the penetration of the cleaning liquid in the holding tank 1.

[0051] In another embodiment, the drain pipe 4 is configured as a straight pipe structure, so that the cleaning liquid can be directly discharged after the blocking member 2 opens the medium channel.

[0052] In a specific implementation, the first switch member 6 is configured as a switch valve, such as a ball valve, a stop valve, a solenoid valve or other switch valves.

[0053] The drainage assembly provided in this embodiment supports the plugging member 2 through the step groove structure 11, and can use the pressure of the cleaning liquid itself to act on the plugging member 2 to seal the connection between the plugging member 2 and the medium channel. The gradient of the layered step groove structure 11 is conducive to increasing the connection contact area between the step groove structure 11 and the plugging member 2, increasing the flow resistance to the downward penetration of the cleaning liquid, and delaying the step-by-step downward penetration of the cleaning liquid. The first switch 6 is installed on the drainage pipe 4 to close the drainage pipe 4 and block the penetration of the cleaning liquid to ensure the amount of cleaning liquid involved in cleaning the container. The utility model has good plugging and sealing capabilities and is suitable for cleaning and drainage operations of containers. The utility model can play a role in sealing and preventing penetration of highly permeable cleaning liquids.

[0054] The method of using the liquid discharge assembly provided by the utility model is as follows:

[0055] In the preparation stage of cleaning the container, the blocking member 2 is placed against the stepped groove structure 11 to block the connection between the medium outlet 12 and the medium channel, and the first switch member 6 and the second switch member 7 are adjusted to a closed state;

[0056] Inject cleaning liquid into the holding tank 1, and place the container to be cleaned in the holding tank 1 for soaking and cleaning;

[0057] After the container is cleaned, when it is necessary to drain the liquid, adjust the first switch member 6 and the second switch member 7 to the open state, remove the blocking member 2, connect the medium outlet 12 and the medium channel, and discharge the cleaning liquid to the external liquid collection device through the medium channel, the filter member 3, and the drain pipe 4.

[0058] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
