[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 1-Figure 7 , which is the first embodiment of the present utility model, provides a liquid level detection device for a beverage filling machine. The liquid level detection device for a beverage filling machine includes a main body component 100, including a disc 101 and an infrared emitter 102, and the infrared emitter 102 is located on one side of the disc 101.

[0032] The infrared transmitter 102 is used to continuously emit infrared signals of a specific wavelength and intensity, providing a signal source for the subsequent liquid level detection process. This is a prior art and will not be elaborated in this solution. Those skilled in the art will be able to clearly understand the working principle.

[0033] The cleaning component 200 is arranged on one side of the infrared emitter 102 and includes a transmission part 201, which is located on one side of the infrared emitter 102 and includes a fixed frame 201a, a rotating ring 201b, a rotating sleeve 201c, a reciprocating roller 201d, a lifting plate 201e, a fixed plate 201f and a torsion spring 201g. The fixed frame 201a is arranged on one side of the disc 101, the rotating ring 201b is located on one side of the fixed frame 201a, the rotating sleeve 201c is inserted into the rotating ring 201b, the reciprocating roller 201d is inserted into the rotating sleeve 201c, the lifting plate 201e is fixed to one side of the reciprocating roller 201d, the fixed plate 201f is fixed to the outside of the rotating ring 201b, and the two ends of the torsion spring 201g are respectively fixed to the rotating ring 201b and the rotating sleeve 201c.

[0034] The rotating ring 201b is connected to the fixed frame 201a by a bearing, and the rotating sleeve 201c is connected to the fixed frame 201a through a bearing. A clamping block 201l is fixed in the rotating sleeve 201c. The clamping block 201l is adapted to the groove set inside the reciprocating roller 201d and is slidably connected, so that the rotating sleeve 201c can drive the reciprocating roller 201d to move in a specific direction through the clamping block 201l when rotating. There are multiple fixed plates 201f, which are evenly distributed on the outside of the rotating ring 201b.

[0035] The rotation of the rotating ring 201b causes the torsion spring 201g to deform, thereby charging the torsion spring 201g and providing energy reserve for the subsequent rotation of the rotating sleeve 201c. When the rotating sleeve 201c rotates, the reciprocating roller 201d cooperates with the block 201l to make the reciprocating roller 201d move vertically back and forth in the rotating sleeve 201c, thereby driving the lifting plate 201e to move vertically.

[0036] The cleaning assembly 200 further includes an auxiliary component 202 disposed on the disc 101 , including a fixed column 202a and a push plate 202b . The fixed column 202a is fixed to the edge of the disc 101 , and the push plate 202b is fixed to the top of the fixed column 202a .

[0037] The fixed column 202a is used to support the push plate 202b, and the push plate 202b is used to push the fixed plate 201f to rotate, thereby driving the rotating ring 201b to rotate. The rotation of the disc 101 drives the push plate 202b to rotate. When the push plate 202b rotates to a position close to the infrared emitter 102, it will contact the fixed plate 201f and apply thrust to the fixed plate 201f, causing the fixed plate 201f to rotate, thereby driving the rotating ring 201b to rotate, thereby providing energy for the subsequent cleaning process.

[0038] Example 2

[0039] Reference Figure 1-Figure 7 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0040] Specifically, the cleaning assembly 200 also includes a locking member 203, which is arranged on one side of the rotating sleeve 201c, including a support plate 203a, a locking block 203b and a first spring 203c. The support plate 203a is arranged on one side of the rotating sleeve 201c, and a slide groove 203a-1 is opened in the support plate 203a. The locking block 203b slides in the slide groove 203a-1. One end of the first spring 203c is fixed to the locking block 203b, and the other end is fixed to the inner wall of the slide groove 203a-1.

[0041] The locking member 203 is configured to limit the rotation of the rotating ring 201b and the rotating sleeve 201c, thereby ensuring that the torsion spring 201g is deformed, providing energy reserves for subsequent cleaning work. The support plate 203a is configured to support the locking block 203b, and the first spring 203c provides thrust for the locking block 203b.

[0042] Specifically, a locking groove 201c-1 is defined in the rotating sleeve 201c, and the locking block 203b can be engaged with the locking groove 201c-1.

[0043] Through the cooperation between the locking block 203b and the locking groove 201c-1, when the two are engaged, the rotating sleeve 201c will not rotate, thereby preventing the rotating sleeve 201c from rotating with the rotating ring 201b when it rotates, causing the torsion spring 201g to be unable to deform. When the two are not engaged, the rotating sleeve 201c can rotate, thereby driving the reciprocating roller 201d to reciprocate.

[0044] Specifically, a push block 201h is fixed outside the rotating ring 201b, and a fixing block 203d is provided on the top of the locking block 203b.

[0045] The pushing block 201h and the fixed block 203d are used to unlock the engagement state of the locking block 203b and the locking groove 201c-1. The rotating ring 201b rotates to drive the pushing block 201h to rotate. When the pushing block 201h rotates to the side of the locking block 203b, the pushing block 201h will contact the fixed block 203d and squeeze the fixed block 203d to move away from the rotating ring 201b. Under the restriction of the sliding groove 203a-1, the fixed block 203d drives the locking block 203b along the direction of the sliding groove 203a-1 away from the locking groove 201c-1, thereby unlocking the restriction on the rotation of the rotating sleeve 201c, ensuring that the rotating sleeve 201c can rotate under the action of the torsion spring 201g and drive the reciprocating roller 201d to move.

[0046] Specifically, a movable groove 201a-1 is defined in the fixed frame 201a, a limiting block 201i is provided in the movable groove 201a-1, a limiting groove 201b-1 is defined in the rotating ring 201b, and the limiting block 201i can be engaged with the limiting groove 201b-1.

[0047] The cooperation between the limiting block 201i and the limiting groove 201b-1 is used to limit the rotation direction of the rotating ring 201b, thereby ensuring that the rotation of the rotating ring 201b can cause the torsion spring 201g to deform.

[0048] Specifically, a second spring 201j is fixed to one end of the limiting block 201i, and the other end of the second spring 201j is fixed to the inner wall of the moving groove 201a-1.

[0049] The second spring 201j is provided to apply a thrust to the limit block 201i, ensuring that the limit block 201i can be engaged with the limit groove 201b-1, thereby avoiding affecting the torsion spring 201g from being unable to charge and provide energy for subsequent cleaning.

[0050] Example 3

[0051] Reference Figure 1-Figure 7 , which is the third embodiment of the present utility model, and is based on the first two embodiments.

[0052] Specifically, one end of the limiting block 201i is inclined.

[0053] The inclined setting ensures that the rotating ring 201b can only rotate in one direction. When the rotating ring 201b rotates, the locking block 203b engages with the locking groove 201c-1, so that the rotating sleeve 201c cannot rotate, thereby causing the torsion spring 201g to deform. When the rotating ring 201b stops rotating, the limiting block 201i cooperates with the limiting groove 201b-1, so that the rotating ring 201b can only rotate in one direction, thereby preventing the rotating ring 201b from reversing under the action of the torsion spring 201g, causing the torsion spring 201g to recover and resulting in the inability to store energy.

[0054] Specifically, a cleaning brush 201k is fixed to one side of the lifting plate 201e.

[0055] When the cleaning brush 201k is in working state, it can contact the surface of the infrared emitter 102 and move under the action of a specific driving mechanism to clean the infrared emitter 102, remove dust, dirt and other impurities on its surface, and ensure the normal operation of the infrared emitter 102 and the accuracy of liquid level detection.

[0056] Specifically, a slot 101 - 1 is defined in the disc 101 .

[0057] There are multiple slots 101 - 1 for supporting and positioning beverage bottles, ensuring that the beverage bottles can be moved to accurate positions and ensuring filling accuracy.

[0058] Specifically, the main component 100 also includes a motor 103, a workbench 104, a filling mechanism 105 and an infrared liquid level detection device 106. The motor 103 is fixed to the bottom of the disc 101, the workbench 104 is arranged on the disc 101, the filling mechanism 105 is fixed on the workbench 104, and the infrared liquid level detection device 106 is fixed to the workbench 104.

[0059] The motor 103 drives the disc 101 to rotate, thereby realizing automatic loading and providing energy for the cleaning component 200. The workbench 104 is used to support the infrared emitter 102 to ensure that the infrared emitter 102 is stably set. The filling mechanism 105 accurately injects the beverage into the beverage bottle. By precisely controlling parameters such as flow rate, pressure and filling time, it is ensured that each beverage bottle can be filled to a predetermined liquid level. The infrared liquid level detection device 106 monitors the liquid level in the container in real time by emitting and receiving infrared signals. It can accurately determine whether the liquid level has reached the predetermined value during the filling process and provide timely feedback information to the filling mechanism 105.

[0060] During use, in the initial state, the locking block 203b is engaged with the locking groove 201c-1, and the limiting block 201i is engaged with the limiting groove 201b-1. At this time, the rotating sleeve 201c cannot rotate, and the rotating ring 201b can only rotate in one direction.

[0061] The motor 103 is started and drives the disc 101 to rotate. When the disc 101 rotates to a position close to the infrared emitter 102, the push plate 202b contacts the fixed plate 201f and applies a thrust to the fixed plate 201f, causing the fixed plate 201f to rotate, thereby driving the rotating ring 201b to rotate. The rotation of the rotating ring 201b causes the torsion spring 201g to deform, thereby charging the torsion spring 201g and providing energy reserve for the subsequent rotation of the rotating sleeve 201c. At the same time, the rotation of the rotating ring 201b drives the push block 201h to rotate. When the push block 201h rotates to one side of the locking block 203b, the push block 201h will contact the fixed block 203d and squeeze the fixed block 203d to move away from the rotating ring 201b, thereby unlocking the rotation limit of the rotating sleeve 201c. At the same time, the disc 101 drives the push plate 202b to continue to rotate, while the position of the push block 201h does not change, and the rotating sleeve 201c can still continue to rotate.

[0062] At this time, the torsion spring 201g will release deformation energy, causing the rotating sleeve 201c to rotate. Through the cooperation of the reciprocating roller 201d and the clamping block 201l, the reciprocating roller 201d will reciprocate vertically in the rotating sleeve 201c, thereby driving the lifting plate 201e to reciprocate vertically, thereby driving the cleaning brush 201k to reciprocate and clean the infrared emitter 102 to remove dust, dirt and other impurities on its surface, ensuring the normal operation of the infrared emitter 102 and the accuracy of liquid level detection.

[0063] When the disc 101 drives the push plate 202b to rotate one circle, it contacts and squeezes the push block 201h again, so that the push block 201h is no longer in contact with the locking block 203b. The first spring 203c pushes the locking block 203b to engage with the locking groove 201c-1, and again limits the rotation of the rotating sleeve 201c, thereby realizing periodic cleaning.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
