Description

Technical Field

[0001] This utility model relates to the field of biological experimental technology, specifically to a handheld steel ball injector. Background Technology

[0002] In life science research (such as plant gene analysis and microbial DNA extraction) and molecular biology experiments, sample grinding and crushing are crucial pretreatment steps. Traditional physical grinding commonly uses centrifuge tubes (11 mm in diameter) as containers. Two 3 mm diameter steel balls are added to the centrifuge tube, and the sample is crushed through the impact and friction of the steel balls using high-speed oscillation or rotation equipment. The number of steel balls added must be precise; too few balls result in insufficient crushing, while too many balls occupy the effective space of the centrifuge tube and increase oscillation resistance.

[0003] Due to the tiny size (3mm) and smooth surface of the steel beads, they easily detach and fall off when added to centrifuge tubes. These detached beads can come into contact with impurities, affecting the purity of DNA / RNA extraction and leading to inaccurate experimental results. Furthermore, the amount of steel beads added is difficult to control; often too many or too few are added, requiring repeated checks, which is time-consuming, laborious, and inefficient. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a handheld steel ball dispenser that can precisely control the separation and output quantity of the balls. It is simple to operate, convenient to use, and achieves efficient and jam-free operation.

[0005] This utility model is achieved through the following technical solution: a handheld steel ball dispenser includes a separator housing. The separator housing has a vertical feeding channel, a horizontal output channel, and a horizontal limiting channel. The upper end of the feeding channel is connected to the output channel to form a T-shaped structure. One end of the output channel is connected to the outside of the separator housing, and the other end is connected to the limiting channel. The output channel and the limiting channel are coaxially arranged. The inner diameter of the feeding channel and the output channel is adapted to the outer diameter of the steel ball. The separator housing has a connecting feeding channel. The feed port has a feeding channel with a top material block that slides along its axial direction and a first spring located below the top material block. The first spring pushes the top material block to slide upward and reset. The output channel has a top material rod that slides along its axial direction. The sliding path of one end of the top material rod passes through the upper end of the feeding channel, and the other end of the top material rod extends into the limiting channel. The limiting channel has a limiting block that slides along its axial direction. The top material rod is fixedly connected to the limiting block. A push rod is fixedly connected to the end of the limiting block away from the top material rod, and the end of the push rod away from the limiting block extends to the outside of the separator housing.

[0006] This design uses a feeding channel to store steel balls, and a first spring elastically drives a top-loading block to transport the steel balls from the feeding channel to the output channel. A limiting channel restricts the movement of a limiting block, causing it to slide the top-loading rod along the output channel, thus ejecting the steel balls. Because the inner diameters of the feeding and output channels are matched to the outer diameters of the steel balls, the feeding channel can only supply one steel ball to the output channel at a time, and the top-loading rod can only eject one steel ball at a time. Therefore, the separator outputs only one steel ball per operation, allowing for precise control of the separation and output quantity of the balls, avoiding errors during steel ball loading, and making it more convenient to use.

[0007] As an optimization, a lever is fixed to the side wall of the top material block, and an elongated sliding hole is provided on the separator housing for the lever to pass through, extending axially along the feeding channel. This optimized design allows the lever to slide along the elongated sliding hole, causing the top material block to slide downwards and compress the first spring, facilitating the replenishment of steel balls into the feeding channel and making operation more convenient.

[0008] As an optimization, the outer diameter of the limiting block is larger than the inner diameter of the output channel. This optimization prevents the limiting block from entering the output channel, thereby achieving the limiting effect of the limiting block and limiting the sliding distance of the top rod.

[0009] As an optimization, a second spring is provided within the limiting channel. The second spring is located on the side of the limiting block away from the push rod. The second spring pushes the limiting block to slide and reset away from the output channel. This optimized solution uses the elasticity of the second spring to drive the sliding of the limiting block, allowing the ejector rod to automatically reset after ejecting the steel ball, facilitating the next ejection operation.

[0010] As an optimization, a pressing handle is fixedly connected to the outer end of the push rod. This optimized solution allows personnel to easily press and push the push rod via the pressing handle, and the pressing handle also limits the sliding distance of the limiting block.

[0011] As an optimization, an arc-shaped limiting groove is formed on the inner wall of the output channel, and the arc-shaped limiting groove is arranged opposite to the feeding channel. This optimization scheme uses the arc-shaped limiting groove to limit the steel balls fed into the output channel, so that the steel balls entering the output channel remain stable and prevent the steel balls from falling off automatically.

[0012] As an optimization, the feed orifice is an elliptical orifice, with the central diameter of the elliptical orifice matching the outer diameter of the steel ball. In this optimized design, the feed orifice is elliptical, allowing only the central portion to pass through the steel ball. During normal use, because the feed inlet is positioned between two steel balls, no single steel ball can be properly positioned, thus preventing leakage.

[0013] As an optimization, the separator housing is a T-shaped structure. This optimization scheme improves the separator housing structure and reduces manufacturing costs.

[0014] The beneficial effects of this utility model are as follows: Steel balls are stored in the feeding channel, and the first spring elastically drives the top material block to transport the steel balls from the feeding channel to the output channel. Pressing the push rod causes the top material rod to slide along the output channel, thereby ejecting the steel balls delivered to the output channel. The elastic push of the second spring allows the top material rod to automatically reset, preparing for the next ejection operation. Simultaneously, the first spring drives the top material block to slide upwards, automatically replenishing the output channel with subsequent steel balls, achieving efficient and jam-free steel ball filling operations. The operation is simple and convenient.

[0015] Because the inner diameters of the feeding and output channels are adapted to the outer diameter of the steel balls, the feeding channel can only supply one steel ball to the output channel at a time, and the ejector rod can only eject one steel ball to the outside at a time. Therefore, the separator only outputs one steel ball per operation, which allows for precise control of the separation and output quantity of the balls, avoids errors during steel ball filling, and makes it more convenient to use.

[0016] This device, through the linkage of a dual-spring mechanism, transforms the user's linear manual input into a single, reliable output for bead separation and automatic feeding, achieving efficient cyclic operation. It is also simple to operate, saves time and effort, and ensures experimental accuracy. Attached Figure Description

[0018] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0019] like Figures 1-6 As shown, a handheld steel ball dispenser includes a separator housing 2, which has a vertical feeding channel 3, a horizontal output channel 4, and a horizontal limiting channel 5.

[0020] The upper end of the feeding channel 3 connects to the output channel 4 to form a T-shaped channel structure. One end of the output channel 4 connects to the outside of the separator housing 2, and the other end connects to the limiting channel 5. The output channel 4 and the limiting channel 5 are coaxially arranged. The inner diameters of the feeding channel 3 and the output channel 4 are adapted to the outer diameter of the steel ball 1, and the inner diameter of the limiting channel 5 is larger than the inner diameter of the output channel 4. Typically, the outer diameter of the steel ball 1 is 3mm, so the inner diameters of the feeding channel 3 and the output channel 4 are 3.1~3.3mm, and the inner diameter of the limiting channel 5 is 3.5~3.7mm. The feeding channel 3, the output channel 4, and the limiting channel 5 can only accommodate one steel ball 1 radially.

[0021] The separator housing 2 has a T-shaped structure. Specifically, the separator housing 2 includes a vertical housing 21 and a horizontal housing 22, with the upper end of the vertical housing 21 fixedly connected to the horizontal housing 22. The feeding channel 3 is located on the vertical housing 21. The output channel 4 and the limiting channel 5 are located on the horizontal housing 22.

[0022] Preferably, the vertical shell 21 and the horizontal shell 22 are integrally molded, which is easy to process and has higher structural strength. The separator shell 2 is made of a transparent material (such as transparent acrylic) to facilitate observation of the state and number of steel balls 1 inside.

[0023] The separator housing 2 has a feed hole 6 that connects to the feeding channel 3. In this embodiment, the feed hole 6 is located on the upper part of the side wall of the vertical housing 21. The feed hole 6 is an elliptical hole, and the central diameter of the elliptical hole is adapted to the outer diameter of the steel ball 1. Steel balls 1 are added to the feeding channel 3 through the feed hole 6. The feed hole 6 is elliptical, and only the central part can pass through the steel ball 1. During normal use, because the feed hole is located in the middle of the two steel balls 1, leakage of steel balls is avoided.

[0024] Preferably, a cap (not shown in the figure) is installed on the feed hole 6. The cap is inserted into the feed hole 6 to block the feed hole 6, which can further prevent the steel ball 1 from leaking out.

[0025] The feeding channel 3 is equipped with a top block 7 that slides axially along its axis, and a first spring 8 located below the top block 7. The first spring 8 pushes the top block 7 upward to slide and reset. In this embodiment, the outer diameter of the top block 7 is adapted to the inner diameter of the feeding channel 3. The lower end of the first spring 8 is fixedly connected to the inner bottom of the feeding channel 3, and the upper end of the first spring 8 is fixedly connected to the top block 7. When the first spring 8 is in its natural state, the top block 7 is located at the upper end of the feeding channel 3. This allows the top block 7 to push out all the steel balls 1 in the feeding channel 3.

[0026] A lever 14 is fixedly connected to the side wall of the top material block 7. An elongated sliding hole 15 is provided on the separator housing 2 for the lever 14 to pass through, extending axially along the feeding channel 3. In this embodiment, the elongated sliding hole 15 is located on the vertical housing 21. By pulling the top material block 7 downwards with the lever 14, the first spring 8 is compressed, facilitating the replenishment of steel balls 1 into the feeding channel 3 through the feed hole 6, making operation more convenient.

[0027] The output channel 4 is equipped with a top rod 9 that slides along its axial direction. One end of the top rod 9 slides through the upper end of the feeding channel 3, and the other end of the top rod 9 extends into the limiting channel 5. The outer diameter of the top rod 9 is adapted to the inner diameter of the output channel 4, so that the top rod 9 slides stably within the output channel 4.

[0028] The limiting channel 5 is provided with a limiting block 10 that slides along its axial direction. The outer diameter of the limiting block 10 is larger than the inner diameter of the output channel 4. The outer diameter of the limiting block 10 and the inner diameter of the limiting channel 5 are matched to prevent the limiting block 10 from entering the output channel 4, thereby achieving the limiting effect of the limiting block 10. The top material rod 9 is fixedly connected to the limiting block 10. A push rod 11 is fixedly connected to the end of the limiting block 10 away from the top material rod 9. The end of the push rod 11 away from the limiting block 10 extends to the outside of the separator housing 2. A pressing handle 12 is fixedly connected to the outer end of the push rod 11. The pressing handle 12 allows personnel to press and push the push rod 11, and also limits the sliding distance of the limiting block 10.

[0029] A second spring 13 is provided within the limiting channel 5. The second spring 13 is located on the side of the limiting block 10 away from the push rod 11. The second spring 13 pushes the limiting block 10 to slide and reset away from the output channel 4. One end of the second spring 13 is fixedly connected to the limiting block 10, and the other end is fixedly connected to the end of the limiting channel 5. When the second spring 13 is in its natural state, the limiting block 10 is located at the end of the limiting channel 5 away from the output channel 4.

[0030] The operator presses the handle 12, causing the limit block 10 to slide, which in turn pushes the ejector rod 9 into the output channel 4. When the end of the ejector rod 9 passes the upper end of the feeding channel 3, it pushes the steel ball 1 outward. At the same time, the ejector rod 9 closes the upper end of the feeding channel 3, preventing subsequent steel balls 1 from entering. After the operator releases the handle 12, the elasticity of the second spring 13 drives the limit block 10 to slide away from the output channel 4, causing the ejector rod 9 to reset and no longer close the feeding channel 3. At the same time, subsequent steel balls 1 in the feeding channel 3 are replenished into the output channel 4, facilitating the next ejector operation.

[0031] Preferably, an arc-shaped limiting groove 16 is provided on the inner wall of the output channel 4, and the arc-shaped limiting groove 16 is arranged opposite to the feeding channel 3. The arc-shaped limiting groove limits the steel ball 1 fed into the output channel 4, so that the steel ball 1 entering the output channel 4 remains stable and prevents the steel ball 1 from falling off automatically.

[0032] Working principle: When the operator pulls lever 14, the top block 7 slides downward, and the operator inserts steel ball 1 into the feeding channel 3 through the feed hole 6. The first spring 8 drives the top block 7 to slide upward, automatically pushing the top steel ball 1 into the output channel 4. The operator presses the handle 12, causing the limit block 10 to slide closer to the output channel 4, and the top rod 9 to slide into the output channel 4, thus pushing one steel ball 1 out of the output channel 4. Simultaneously, the top rod 9 closes the upper end of the feeding channel 3, preventing subsequent steel balls 1 from entering, achieving precise control of the number of steel balls 1 output. After the operator releases the handle 12, the elasticity of the second spring 13 drives the limit block 10 to slide away from the output channel 4, causing the top rod 9 to reset and no longer close the feeding channel 3. At the same time, the top steel ball 1 in the feeding channel 3 is automatically replenished into the output channel 4 for the next output operation.
