Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0029] The following is in conjunction with the appendix Figures 1 to 3The infusion bottle head leakage detection device provided in this application will be described in detail through specific embodiments and application scenarios.
[0030] Please see Figures 1-2 This application discloses an infusion bottle head leakage detection device, which is applied to the leakage detection of an infusion bottle 900, specifically to the leakage detection of the bottle head of the infusion bottle 900. Specifically, the infusion bottle head leakage detection device includes a frame 100, a first electrode 200, a second electrode 300, and a drive assembly 400. The frame 100 is the basic component of the infusion bottle head leakage detection device, providing a mounting base for the first electrode 200, the second electrode 300, and the drive assembly 400; that is, the first electrode 200, the second electrode 300, and the drive assembly 400 can be directly or indirectly attached to the frame 100 for installation.
[0031] In this embodiment, the first electrode 200 is disposed on the frame 100. For example, the first electrode 200 can be a negative electrode brush. When the infusion bottle 900 is conveyed through the frame 100, the first electrode 200 contacts the body of the infusion bottle 900. The second electrode 300 is connected to the drive assembly 400. When the infusion bottle 900 is conveyed through the frame 100, the second electrode 300 is adjacent to the infusion bottle 900. For example, the second electrode 300 can be in the form of a positive electrode plate. The drive assembly 400 is used to drive the second electrode 300 to rotate around the head of the infusion bottle 900.
[0032] During specific leak detection, when the bottle head is intact, the infusion bottle 900 acts as an insulator, forming a capacitance between itself and the first electrode 200 and the second electrode 300. The capacitance between the first electrode 200 and the second electrode 300 is relatively large, resulting in a relatively small induced microcurrent. However, when a leak occurs at the bottle head, the capacitance formed between the infusion bottle 900 and the first electrode 200 and the second electrode 300 disappears or decreases. At this time, a circuit is formed between the first electrode 200 and the second electrode 300, and the current can flow directly through the leak to the negative electrode brush, causing the microcurrent to increase. The generated microcurrent can be measured by the detection circuit to determine whether a leak has occurred at the bottle head of the infusion bottle 900.
[0033] Based on the above technical solution, when the infusion bottle 900 is conveyed through the bottle head leakage detection device, the first electrode 200 remains in contact with the bottle body of the infusion bottle 900, and the driving component 400 drives the second electrode to rotate around the bottle head of the infusion bottle 900. This ensures that the detection range of the second electrode 300 can cover all surfaces and corners of the bottle head, thereby comprehensively detecting potential leakage points. It has the characteristics of convenient and high accuracy in bottle head leakage detection.
[0034] In this embodiment, the first electrode 200 is in the form of an electric brush. The electric brush typically has soft bristles or filaments. These bristles can adapt to the slight unevenness of the bottle surface, ensuring good electrical contact. At the same time, the softness of the electric brush allows it to maintain stable contact on bottles of different diameters and shapes without damaging the bottle. The second electrode 300 adopts a sheet-like structure. The electric field formed between the sheet-like second electrode 300 and the bottle head is more uniform. When applied to leak detection of the bottle head, it is more helpful in detecting small leaks occurring at the bottle head.
[0035] In the embodiments of this application, please refer to Figure 2 The infusion bottle head leakage detection device also includes a bracket 500, which provides a mounting base for the second electrode 300. The second electrode 300 is mounted on the bracket 500. The bracket 500 is connected to the output end of the drive assembly 400. The drive assembly 400 drives the second electrode 300 to rotate around the infusion bottle 900 by driving the bracket 500 to rotate.
[0036] For further technical solutions, please refer to [link / reference]. Figure 2 and Figure 3 Two second electrodes 300 are disposed opposite to each other on the support 500, and a gap region 600 is defined between the two second electrodes 300. The gap region 600 is used for the bottle head of the infusion bottle 900 to pass through. With this arrangement, on the one hand, by setting two opposite second electrodes 300, the detection efficiency of the bottle head of the infusion bottle 900 can be improved. On the other hand, the opposite arrangement of the two second electrodes 300 can form a relatively stable electric field environment. This layout helps to reduce the influence of external interference on the detection structure and improve the stability and accuracy of the detection.
[0037] In the embodiments of this application, please continue to refer to Figure 2 The infusion bottle head leakage detection device may also include an elastic element 700. The second electrode 300 is floatingly mounted on the support 500 via the elastic element 700. Through the floating design, when the bottle head of the infusion bottle 900 enters the gap area 600, if the infusion bottle 900 comes into contact with the second electrode 300 due to its own dimensional error or shaking during transportation, the elastic element 700 can be compressed and elastically deformed, so that the second electrode 300 avoids the bottle head of the infusion bottle 900, thereby effectively avoiding a rigid impact between the bottle head of the infusion bottle 900 and the second electrode 300, thus preventing damage to the second electrode 300 or the bottle head.
[0038] In this embodiment, the bracket 500 includes a base plate 510 and a mounting plate 520. The mounting plate 520 is rotatably connected to the base plate 510. The second electrode 300 is disposed on the mounting plate 520. The elastic element 700 can be a torsion spring sleeved on the rotation shaft of the mounting plate 520. One end of the torsion spring is connected to the base plate 510, and the other end of the torsion spring is connected to the mounting plate 520. By setting the bracket 500 as a separate base plate 510 and mounting plate 520, and disposing the second electrode 300 on the mounting plate 520, the second electrode 300 is floating on the bracket 500.
[0039] In some optional embodiments of this application, the second electrode 300 can be electrically connected by a wire. It is understood that when the second electrode 300 is electrically connected by a wire, the rotation angle of the bracket 500 is usually less than 180° to avoid the wire from becoming tangled or being pulled and broken.
[0040] In some optional embodiments of this application, the infusion bottle head leakage detection device further includes a conductive assembly 800. The conductive assembly 800 includes a conductive frame 810 and an electrical contact 820 rotatably disposed on the conductive frame 810. The electrical contact 820 makes rolling contact with the rotation axis of the support 500 to electrically connect with the second electrode 300. The rolling contact between the electrical contact 820 and the support 500 ensures that the support 500 maintains good contact with the electrical contact 820 during rotation, thereby ensuring stable transmission of electrical signals. In contrast, wired connections may cause unstable transmission of electrical signals due to loosening or wear at the connection point.
[0041] In a further technical solution, the end of the second electrode 300 is bent to form a guide portion 310. The guide portions 310 of the two opposing second electrodes 300 are bent in opposite directions. In this way, the guide portions 310 of the two second electrodes 300 are constricted. When the bottle head of the infusion bottle 900 enters the gap area 600, even if the infusion bottle 900 moves slightly, it will gradually adapt to and conform to the shape of the second electrode 300. That is to say, along the delivery direction of the infusion bottle 900, the guide portion 310 can stably guide the bottle head of the infusion bottle 900 into the space between the two second electrodes 300. This gradual transition design reduces the direct collision and friction between the bottle head and the second electrode 300, thereby reducing the risk of damage to the second electrode 300 and the bottle head.
[0042] In this embodiment of the application, the drive assembly 400 includes a motor and a plurality of first gears 420 driven by the motor to rotate. The bracket 500 has a rotating shaft, which is connected to the first gears 420. The motor drives the bracket 500 to rotate, thereby enabling the two second electrodes 300 to rotate around the bottle head of the infusion bottle 900.
[0043] In a further technical solution, the drive assembly 400 may also include a transition gear 430, which meshes with the two first gears 420 so that the two first gears 420 rotate in the same direction, that is, the rotation pace of all supports 500 is consistent. This consistency can avoid conflicts or interference between components caused by asynchrony, thereby improving the coordination and stability of the entire detection device.
[0044] In this embodiment, the infusion bottle head leakage detection device further includes a conveying unit connected to the frame 100, which enables the first electrode 200 and the second electrode 300 to move synchronously relative to the infusion bottle 900. That is, based on the conveying function of the conveying unit on the frame 100, the first electrode 200 and the second electrode 300 can synchronously track and detect the infusion bottle 900. The first electrode 200 and the second electrode 300, which move synchronously with the infusion bottle 900, can track the position and state of the infusion bottle 900 in real time, thereby ensuring sufficient discharge detection time and ensuring the real-time performance and accuracy of the detection data.
