Description

Technical Field

[0001] This utility model relates to the field of ink bottle flow rate adjustment technology, and in particular to a squeeze-type ink refill bottle with adjustable flow rate. Background Technology

[0002] When using an inkjet printer, if the ink in the ink tank runs out, it is necessary to refill the ink tank with an ink refill bottle.

[0003] Most existing ink refill bottles use a squeeze-type structure, where ink is squeezed out of the ink outlet to complete the refilling process.

[0004] Existing ink refill bottles are mostly simple squeeze-type bottle structures with a fixed orifice design, making it impossible to adjust the ink flow rate according to actual refilling needs. This fixed-flow refill bottle has several drawbacks: firstly, when rapid ink refilling is required, the fixed small-diameter orifice results in low refilling efficiency and prolonged time; secondly, when refilling small ink tanks or ink tanks in high-precision equipment, the fixed large-diameter orifice can easily lead to excessive and rapid ink flow, wasting ink, potentially causing ink overflow and contaminating the equipment, or even affecting its normal operating performance. Therefore, an adjustable-flow squeeze-type ink refill bottle is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable flow rate squeeze-type ink refill bottle, aiming to solve the problem that the flow rate of ink refill bottles in the prior art cannot be adjusted.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable flow rate squeeze-type ink refill bottle, comprising a bottle body, a port fixedly connected to the end of the bottle body, an adjusting bottle opening threadedly connected to the surface of the port, and a flow rate regulating device disposed inside the adjusting bottle opening; the flow rate regulating device includes a fixed valve plate, the fixed valve plate being fixedly connected to the inside of the adjusting bottle opening, an adjusting valve plate being rotatably connected to one side of the fixed valve plate, a connecting block being fixedly connected to the adjusting valve plate, and a rotating ring being fixedly connected to the end of the connecting block.

[0007] As a further description of the above technical solution: Both the fixed valve plate and the regulating valve plate are provided with regulating valve ports, and the surface of the connecting block is slidably connected to the inside of the regulating bottle port.

[0008] As a further description of the above technical solution: The rotating ring is fitted onto the adjusting bottle opening, and an auxiliary rotating plate is fixedly connected to the surface of the rotating ring.

[0009] As a further description of the above technical solution: A sealing ring is fitted onto the port to increase the sealing between the port and the bottle neck.

[0010] As a further description of the above technical solution: The end of the regulating bottle opening is fitted with a protective sleeve, which is used to seal and protect the regulating bottle opening.

[0011] As a further description of the above technical solution: The regulating bottle opening is provided with a positioning groove at the rotating ring. The positioning groove is provided in multiple ways and is arranged in a circular array on the regulating bottle opening.

[0012] As a further description of the above technical solution: The inner ring of the rotating ring is fixedly connected to a spring button, and the surface of the spring button is elastically engaged with the inside of the positioning groove.

[0013] As a further description of the above technical solution: The surface of the adjustable bottle opening is provided with a limiting groove, and the surface of the connecting block is slidably connected to the inner wall of the limiting groove.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by setting a flow adjustment device, the flow rate can be adjusted by the cooperation of the fixed valve plate and the adjusting valve plate.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-2 The present invention provides an embodiment of an adjustable flow rate squeeze-type ink refill bottle, comprising a bottle body 1, a port 2 fixedly connected to the end of the bottle body 1, an adjusting bottle opening 3 threadedly connected to the surface of the port 2, and a flow rate regulating device 4 disposed inside the adjusting bottle opening 3; the flow rate regulating device 4 includes a fixed valve plate 41, which is fixedly connected to the inside of the adjusting bottle opening 3, an adjusting valve plate 42 rotatably connected to one side of the fixed valve plate 41, a connecting block 43 fixedly connected to the adjusting valve plate 42, and a rotating ring 44 fixedly connected to the end of the connecting block 43. By setting the flow rate regulating device 4, the flow rate is adjustable through the cooperation of the fixed valve plate 41 and the adjusting valve plate 42. The operator only needs to rotate the rotating ring 44 to drive the adjusting valve plate 42 to rotate, changing the overlapping area of ​​the adjusting valve openings on the two valve plates, thereby flexibly adjusting the ink outflow rate. It can freely switch between rapid replenishment and precise replenishment according to replenishment needs, effectively balancing replenishment efficiency and accuracy, and avoiding ink waste and equipment contamination.

[0020] Reference Figures 2-4 Both the fixed valve plate 41 and the regulating valve plate 42 are provided with regulating valve ports. By rotating the regulating valve plate 42, the overlapping area of ​​the regulating valve ports on the two valve plates can be changed, thereby realizing the regulation of ink outflow. The rotating ring 44 is sleeved on the regulating bottle mouth 3. An auxiliary rotating plate 45 is fixedly connected to the surface of the rotating ring 44. The auxiliary rotating plate 45 provides a force point for the operator to rotate the rotating ring 44, reducing the difficulty of the adjustment operation. A limiting groove 31 is provided on the surface of the regulating bottle mouth 3. The surface of the connecting block 43 is slidably connected to the inner wall of the limiting groove 31 to ensure the stability of the regulating valve plate 42 during rotation.

[0021] Reference Figure 2 A sealing ring 5 is fitted on port 2. The sealing ring 5 is used to increase the sealing between port 2 and the regulating bottle mouth 3 to prevent ink from leaking from the threaded connection between the two. A protective sleeve 6 is fitted on the end of the regulating bottle mouth 3. The protective sleeve 6 is used to seal and protect the regulating bottle mouth 3 to prevent dust and impurities from entering the bottle and contaminating the ink when it is not in use.

[0022] Reference Figures 3-4 A positioning groove 47 is provided on the regulating bottle mouth 3 at the rotating ring 44. Multiple positioning grooves 47 are arranged in a ring array on the regulating bottle mouth 3. A spring button 46 is fixedly connected to the inner ring of the rotating ring 44. The surface of the spring button 46 is elastically engaged with the inside of the positioning groove 47. By engaging the spring button 46 with different positioning grooves 47, the adjusted rotating ring 44 can be positioned to prevent it from rotating due to accidental contact and causing flow deviation.

[0023] Working principle: Before refilling ink using this ink refill bottle, remove the protective sleeve 6 fitted onto the end of the regulating bottle opening 3 to expose the ink outlet. Adjust the flow rate according to the actual ink refill requirements: The operator uses their finger to turn the auxiliary rotating plate 45, causing the rotating ring 44 to rotate on the regulating bottle opening 3. The rotating ring 44 drives the regulating valve plate 42 to rotate on the side of the fixed valve plate 41 through the connecting block 43. At this time, the spring button 46 is squeezed by the surface of the regulating bottle opening 3 and undergoes elastic deformation, disengaging from the current positioning groove 47 and sliding along the surface of the regulating bottle opening 3. When it rotates to the position corresponding to the target flow rate, the spring button 46, under its own elastic action, engages in the corresponding positioning groove 47, completing the positioning of the rotating ring 44. At this time, the fixed valve plate 41 and the regulating valve port on the regulating valve plate 42 form a specific overlapping area, corresponding to the required ink outflow rate. After the flow rate is adjusted, the ink outlet end of the regulating bottle port 3 is aligned with the ink tank inlet of the inkjet equipment, and the bottle body 1 is gently squeezed. Under the action of the squeezing force, the ink in the bottle body 1 passes through the port 2 and the inside of the regulating bottle port 3 in sequence, and flows out through the regulating valve ports of the fixed valve plate 41 and the regulating valve plate 42, and is injected into the ink tank. During the replenishment process, the sealing ring 5 on the port 2 ensures the sealing of the connection between the bottle body 1 and the regulating bottle port 3 to prevent ink leakage; the sliding fit of the connecting block 43 in the limiting groove 31 ensures the stability of the regulating valve plate 42 after rotation adjustment and ensures uniform flow rate. If the replenishment flow rate needs to be changed, the auxiliary rotating plate 45 can be turned again, and the above adjustment steps can be repeated. The flow rate can be adjusted by changing the overlapping area of ​​the two valve plates' regulating valve ports: when the two valve plates' regulating valve ports are completely overlapping, the outflow flow rate is the maximum, suitable for rapid replenishment; when the two valve plates' regulating valve ports are partially overlapping, the outflow flow rate is moderate; when the two valve plates' regulating valve ports are completely offset, the ink stops flowing out, which can temporarily interrupt the replenishment process. After the ink replenishment is completed, stop squeezing the bottle body 1, turn the auxiliary rotating plate 45 again to completely offset the two valve plates' regulating valve ports, close the ink outflow channel, and then put the protective sleeve 6 back on the end of the regulating bottle port 3 to complete the sealing protection. When it is necessary to clean or maintain the replenishment bottle, the regulating bottle port 3 can be rotated to separate it from the port 2, and the components can be cleaned. The operation is convenient.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
