[0002] In the assembly process, glue injection is often required. The conventional method involves workers manually squeezing the bottle to inject glue into the connector holes. However, manually squeezing the bottle makes it difficult to control the amount of glue injected. Inconsistent glue levels, both in the bottle and with varying pressure applied by the worker, can lead to inconsistent glue amounts. Insufficient glue can cause connectors to detach, while excessive glue can cause overflow, both negatively impacting product quality. Utility Model Content

[0003] The present invention aims to at least partially solve one of the aforementioned technical problems in the related art. To this end, the present invention proposes a dispensing device.

Detailed Implementation

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] This utility model relates to a dispensing device, including a container 100 and a piston 200.

[0028] like Figure 1 and Figure 2As shown, container 100 includes a receiving cavity 101 and a dispensing cavity 102. The dispensing cavity 102 has a dispensing port 103. A through-hole 104 is provided between the receiving cavity 101 and the dispensing cavity 102, connecting them. A piston 200 is installed in the dispensing cavity 102 and can translate within it. The piston 200 includes a plug portion 210 and an ejector pin portion 220. The plug portion 210 moves within the dispensing cavity 102 in a direction approaching or away from the dispensing port 103. In the illustrated direction, the dispensing port 103 faces downwards, and the plug portion 210 moves up and down within the dispensing cavity 102. The plug portion 210 is connected to the ejector pin portion 220, and the two can be integrally formed. The ejector pin portion 220 passes through the dispensing port 103 and can extend downwards out of the dispensing port 103. There is a gap between the ejector pin 220 and the glue outlet 103. Glue is stored in the cavity 101. In the initial state, as... Figure 2 As shown, the ejector pin 220 extends beyond the dispensing port 103. When dispensing glue to an object, the dispensing device is inverted, with the dispensing port 103 facing the location on the object where glue needs to be dispensed. The ejector pin 220 abuts against the dispensing location, and the user holds the container 100 and presses it down. Figure 3 As shown, the ejector pin 220 retracts upwards towards the dispensing cavity 102, and the plug 210 moves upwards accordingly. Glue in the container 101 flows into the dispensing cavity 102 through the glue outlet 104, and then flows out through the gap between the dispensing outlet 103 and the ejector pin 220 to the dispensing position on the object. Then, the container 100 is lifted, and the plug 210 drives the ejector pin 220 to move downwards and reset. When the plug 210 moves downwards, it pushes the glue in the dispensing cavity 102 through the gap between the dispensing outlet 103 and the ejector pin 220 to be quickly discharged. By controlling the downward pressure depth of the container 100 relative to the object, the amount of retraction of the plug 210 and the ejector pin 220 is controlled, thereby controlling the amount of glue discharged through the plug 210 when the piston 200 resets downwards, which in turn controls the amount of glue injected to the dispensing position. The overall structure is simple and the operation is easy. By controlling the retraction distance of the piston 200, the amount of glue injected can be changed, which greatly improves the glue dispensing quality of the object.

[0029] In one embodiment, the plug portion 210 has a limit position when it moves towards the dispensing port 103. As shown in the diagram, when the plug portion 210 moves downwards towards the dispensing port 103, it can no longer move downwards after reaching a certain position in the dispensing cavity 102; this position is defined as the limit position of the plug portion 210's downward movement. When the plug portion 210 is at its limit position, the length of the ejector pin portion 220 extending beyond the dispensing port 103 reaches its maximum, and at this time, the piston component 200 blocks at least one of the through port 104 and the dispensing port 103. This can be done by blocking the through port 104 alone, blocking the dispensing port 103 alone, or blocking both the through port 104 and the dispensing port 103 simultaneously. When the stopper 210 moves upward away from the glue outlet 103, it moves away from its limit position. Both the glue inlet 104 and the glue outlet 103 open, allowing the glue in the cavity 101 to flow into the glue outlet cavity 102 through the glue inlet 104 and then out through the glue outlet 103. Normally, the stopper 210 remains at its limit position. During use, the stopper 210 moves away from its limit position, allowing the glue to drain smoothly. Once the stopper 210 returns to its limit position, glue dispensing stops, thus effectively controlling the amount of glue dispensed.

[0030] The structure that restricts the plug portion 210 to its extreme position can be achieved by providing a limiting structure between the piston member 200 and the dispensing cavity 102. For example, a guide groove can be provided on the side wall of the dispensing cavity 102, and a slider can be provided on the piston member 200, with the slider sliding within the guide groove. The guide groove limits the stroke position of the slider, thereby limiting the extreme position of the plug portion 210. In this embodiment, as shown... Figure 1 and Figure 2 As shown, the ejector pin portion 220 is provided with a protrusion 230. When the plug portion 210 moves to its limit position, the protrusion 230 blocks the glue outlet 103. At this time, the protrusion 230 can abut against the glue outlet 103, thereby limiting the limit position of the plug portion 210. Furthermore, the protrusion 230 can be configured as a cylinder, protruding radially along the ejector pin portion 220. The minimum outer diameter of the protrusion 230 is greater than the maximum inner diameter of the glue outlet 104. When the plug portion 210 moves to its limit position, the protrusion 230 abuts against the side of the glue outlet 104 near the glue dispensing cavity 102, thereby blocking the glue outlet 103.

[0031] In another embodiment, such as Figure 2 As shown, the glue outlet 104 is located on the moving path of the plug 210. When the plug 210 moves to its limit position, it blocks the glue outlet 104. When the plug 210 moves upward away from its limit position, it leaves the glue outlet 104, and the glue outlet 104 opens to connect the cavity 101 and the dispensing cavity 102.

[0032] The piston 200 can be reset to its extreme position by having one end extending outside the cavity 101, away from the outlet 103, and by using external force to push the piston 200 to reset. In one embodiment, as shown... Figure 2 and Figure 4 As shown, the dispensing chamber 102 is divided into a first chamber 105 and a second chamber 106 by the plug portion 210. In the illustrated direction, the second chamber 106 and the first chamber 105 are vertically distributed, with the first chamber 105 located below the plug portion 210 and the second chamber 106 located above the plug portion 210. The volumes of the first chamber 105 and the second chamber 106 dynamically change according to the position of the plug portion 210. The first chamber 105 communicates with the dispensing port 103. An elastic element 300 is installed in the second chamber 106. The elastic element 300 can be a spring or the like. The elastic element 300 applies an elastic force to the plug portion 210, causing it to move closer to the dispensing port 103. Under the elastic force of the elastic element 300, the plug portion 210 is normally held at its limit position. During use, after the piston 200 retracts, the piston 200 can return to its original position under the elastic force of the elastic element 300, simultaneously pushing the glue out of the dispensing port 103.

[0033] In one embodiment, such as Figure 1 As shown, container 100 includes a bottle body 110, a cap 120, and a nozzle 130. The interior of the bottle body 110 forms a cavity 101. The cap 120 is connected to the bottle body 110. The nozzle 130 is connected to the cap 120. A dispensing cavity 102 is defined between the nozzle 130 and the cap 120. A glue inlet 104 is formed on the cap 120, and a glue outlet 103 is formed on the nozzle 130. The bottle body 110, cap 120, and nozzle 130 can be disassembled to clean the cavity 101, glue inlet 104, dispensing cavity 102, and dispensing outlet 103.

[0034] Among them, such as Figure 1 and Figure 4 As shown, the bottle cap 120 includes a connecting portion 121, a first cylindrical portion 122, and a second cylindrical portion 123. The connecting portion 121 is connected to the bottle body 110, and the two can be connected by a snap-fit ​​or a threaded connection. The first cylindrical portion 122 and the second cylindrical portion 123 are located on both sides of the connecting portion 121, respectively. The first cylindrical portion 122 and the second cylindrical portion 123 are coaxially arranged and communicate with each other. The second cylindrical portion 123 extends into the cavity 101. An adhesive outlet 104 is formed on the side wall of the second cylindrical portion 123. A stopper portion 210 is movably installed in the second cylindrical portion 123. The aforementioned elastic member 300 can be installed in the second cylindrical portion 123. The end of the first cylindrical portion 122 away from the second cylindrical portion 123 is open, and the open end of the first cylindrical portion 122 is connected to the bottle mouth 130, and the two can be connected by a threaded connection or a snap-fit, etc.
