Description

Technical Field

[0001] This utility model belongs to the technical field of milk refrigerator boxes and relates to a milk refrigerator box liquid level detection device. Background Technology

[0002] A milk refrigerator box is a refrigerator accessory used to store fresh milk by placing it inside the refrigerator.

[0003] Traditional milk refrigerator boxes cannot be used to observe the level of milk inside. When milk is pumped to the bottom, it is easy to cause a dry pumping phenomenon, which affects the operator's ability to add milk to the milk refrigerator box in a timely manner. To solve the above technical problems, we designed a milk refrigerator box liquid level detection device. Summary of the Invention

[0004] The purpose of this invention is to provide a milk refrigerator box liquid level detection device to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solution: A milk refrigerator box liquid level detection device includes a milk box, which is composed of a box shell and a box inner liner. The box inner liner is fixedly installed inside the box shell. Two inner liner inserts are fixedly installed at the bottom of the box inner liner. Support columns are fixedly installed at the four corners of the bottom of the milk box. Milk box inserts are fixedly installed inside the two support columns located on the same side. The inner liner inserts are connected to the milk box inserts through metal strips.

[0006] In the above-mentioned milk refrigerator box liquid level detection device, the top of the milk box is covered with a milk box lid, and a locking component is provided between the milk box lid and the milk box.

[0007] In the above-mentioned milk refrigerator box liquid level detection device, the locking assembly includes two locking blocks and two return springs. Rectangular grooves are provided on both sides of the milk box lid. Locking blocks are nested inside the two rectangular grooves. Return springs are fixedly installed at the bottom of the two rectangular grooves. One end of the return spring is fixedly connected to one end of the locking block. Locking slots are provided on the top of both sides of the inner wall of the milk box. The locking blocks are engaged with the locking slots.

[0008] In the above-mentioned milk refrigerator box liquid level detection device, the top of the rectangular groove is provided with a strip-shaped through groove that communicates with the outside. A push block is slidably connected inside the strip-shaped through groove, and the bottom end of the push block is fixedly connected to one side of the top of the card block.

[0009] In the aforementioned milk refrigerator box liquid level detection device, the surface of the milk box is engraved with scale markings.

[0010] In the aforementioned milk refrigerator box liquid level detection device, a sealing ring is fitted at the connection between the milk box and the milk box lid.

[0011] Compared with the prior art, the advantages of this utility model of a milk refrigerator carton liquid level detection device are as follows: through the cooperation of the inner liner insert and the milk carton insert, when the liquid level is above the inner liner insert, the two inner liner inserts are connected and the signal is transmitted to the computer motherboard. When working normally, there is no alarm. During the milk pumping process, when the milk level is below the inner liner insert, causing the two inner liner inserts to lose connection, the signal is transmitted to the computer motherboard, and the operation panel issues a milk shortage alarm.

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a milk refrigerator carton liquid level detection device, including a milk carton 1. The milk carton 1 is composed of a carton shell 8 and a carton inner liner 9. The carton inner liner 9 is fixedly installed inside the carton shell 8. Two inner liner inserts 7 are fixedly installed at the bottom of the carton inner liner 9. Support columns 4 are fixedly installed at the four corners of the bottom of the milk carton 1. Milk carton inserts 5 are fixedly installed inside the two support columns 4 located on the same side. The inner liner inserts 7 are connected to the milk carton inserts 5 through metal strips 6.

[0018] Specifically, through the cooperation of the inner liner insert 7 and the milk carton insert 5, when the liquid level is above the inner liner insert 7, the two inner liner inserts 7 are connected and the signal is transmitted to the computer motherboard. When working normally, there is no alarm. During the milk pumping process, when the milk level is below the inner liner insert 7, the two inner liner inserts 7 are not connected, the signal is transmitted to the computer motherboard, and the control panel issues a milk shortage alarm.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a milk refrigerator box liquid level detection device. The top of the milk box 1 is covered with a milk box lid 2, and a locking component is provided between the milk box lid 2 and the milk box 1.

[0020] The locking assembly includes two locking blocks 11 and two return springs 13. Rectangular slots 12 are provided on both sides of the milk box lid 2. The locking blocks 11 are nested inside the two rectangular slots 12. The return springs 13 are fixedly installed at the bottom of the two rectangular slots 12. One end of the return spring 13 is fixedly connected to one end of the locking block 11. The top of both sides of the inner wall of the milk box 1 is provided with locking grooves 10. The locking blocks 11 are locked and connected to the locking grooves 10.

[0021] The top of the rectangular groove 12 is provided with a strip-shaped through groove that communicates with the outside. A push block 14 is slidably connected inside the strip-shaped through groove. The bottom end of the push block 14 is fixedly connected to one side of the top of the locking block 11.

[0022] Specifically, through the cooperation of the reset spring 13 and the push block 14, the push block 14 pushes the extension and retraction of the locking block 11, so that the locking block 11 engages and disengages from the locking slot 10, which facilitates the limiting and fixing of the milk box lid 2.

[0023] The surface of the milk box 1 is engraved with scale markings 3. Specifically, the scale markings 3 make it easy to observe the amount of milk inside the milk box 1.

[0024] A sealing ring is fitted at the connection between the milk box 1 and the milk box lid 2. Specifically, the sealing ring improves the airtightness of the connection between the milk box 1 and the milk box lid 2.

[0025] In specific implementation, when using the milk box 1, the full milk box 1 is placed inside the refrigerator. The milk box insert 5 and the inner liner insert 7 of the milk box 1 are in contact. Because the milk box is full, the liquid level is above the inner liner insert 7, and the two inner liner inserts 7 are connected. The signal is transmitted to the computer motherboard, and the operation is normal without any alarm. During the milk dispensing process, when the milk level is lower than the inner liner insert 7, the two inner liner inserts 7 are no longer connected. The signal is transmitted to the computer motherboard, and the control panel issues a milk shortage alarm.
