Description

Technical Field

[0001] This application relates to the field of laboratory sampling equipment, specifically to a gear-vibrating sampling spoon. Background Technology

[0002] In laboratories, the sampling spoon is a commonly used tool for sampling and weighing. The process generally involves scooping a solid sample with the spoon, then shaking the wrist on a balance to transfer the sample from the spoon into a weighing cup or weighing paper to obtain the desired sample volume. However, this method relies heavily on experience, often resulting in problems such as insufficient wrist shaking leading to long weighing times, or excessive shaking causing the added sample to exceed the expected amount, necessitating a restart. This affects weighing efficiency and prolongs weighing time. Therefore, improvements to the measuring spoon are needed to obtain the required sample volume more quickly. Utility Model Content

[0003] In view of this, this application provides a gear-driven vibrating sampling spoon, the main purpose of which is to solve the problem of low weighing efficiency caused by over-reliance on human experience when using laboratory spoons for sampling and weighing. By controlling the speed of gear rotation, the frequency and amplitude of the small spoon's vibration can be controlled, thereby better controlling the amount of sample added and improving sample dispensing efficiency.

[0004] To achieve the purpose of this utility model patent, the technical solution adopted in this application is as follows: A gear-vibrating sampling spoon includes a spoon head, a spoon handle, and a vibrating structure disposed on the spoon handle. When the vibrating structure is driven, it causes the spoon head to vibrate.

[0005] In some embodiments, the vibration structure includes an upper gear and a lower gear, which are rotatably connected to the spoon handle. The upper gear meshes with the lower gear, and when the upper gear is driven, it drives the lower gear to vibrate, thereby causing the spoon head to vibrate synchronously.

[0006] In some embodiments, the spoon handle includes an upper spoon handle, a connector, and a lower spoon handle, wherein the connector is located between the upper spoon handle and the lower spoon handle so that the upper spoon handle is connected to the lower spoon handle via the connector.

[0008] In some embodiments, the upper gear is rotatably mounted on the end of the upper spoon handle, and the lower gear is rotatably mounted on the end of the lower spoon handle.

[0009] In some embodiments, the rotation axis of the upper gear is collinear with the longitudinal axis of the upper spoon handle; the rotation axis of the lower gear is collinear with the longitudinal axis of the lower spoon handle.

[0010] In some embodiments, the diameters of the upper gear and the lower gear are 1.1 to 2 times the width of the spoon handle.

[0011] In some embodiments, the connector is a sheet-like structure, with a first shaft hole and a second shaft hole respectively provided at both ends of the connector, and the ends of the upper spoon handle and the lower spoon handle are respectively inserted into the first shaft hole and the second shaft hole.

[0012] In some embodiments, the second shaft hole of the connector is 1cm-5cm away from the spoon head.

[0013] In some embodiments, the spoon head is an open arc shape, and the central axis of the spoon head and the spoon handle are on the same straight line.

[0014] (1) This application adjusts the vibration frequency and amplitude of the medicine spoon by controlling the vibration of the gear, so that the sample is added more evenly during weighing and the weighing efficiency is improved; (2) This application does not require a complex electric control device.

[0023] The present utility model patent will be further described below with reference to the accompanying drawings and embodiments: like Figure 1As shown in the figure, one embodiment of this utility model provides a gear-driven vibrating sampling spoon, including a spoon head 1, a spoon handle 2, and a vibrating structure 3 disposed on the spoon handle 2. When driven, the vibrating structure 3 drives the spoon head 1 to vibrate. The spoon head 1 is used to hold samples, and its shape allows it to hold a sufficient amount of sample at once. When adding samples, the vibrating structure 3 drives the spoon head 1 to vibrate. The vibration amplitude and frequency of the spoon head 3 are controlled by the pushing force and frequency to control the sample to be added evenly to the weighing paper or weighing cup, thereby improving the weighing efficiency. The vibrating structure 3 is a non-electric, mechanical vibration source. This embodiment provides a gear-driven vibrating sampling spoon, suitable for the separation and weighing of routine solid samples in the laboratory. Solid samples can be powdered or granular. The core of the above design lies in the precise control of the spoon head vibration through a mechanical gear transmission structure, solving the problems of low efficiency and poor accuracy of traditional wrist-shaking operation.

[0024] The vibration structure 3 includes an upper gear 31 and a lower gear 32, which are rotatably connected to the spoon handle 2. The upper gear 31 and the lower gear 32 mesh with each other. When the upper gear 31 is driven, it drives the lower gear 32 to vibrate, thereby causing the spoon head 1 to vibrate synchronously. The above design achieves vibration transmission through gear meshing. The structure is simple and reliable with high transmission efficiency. The vibration of the lower gear and the spoon head can be caused by manually or with a slight external force driving the upper gear, without the need for an additional power source, making it easy to operate and control in the experimental environment.

[0025] The spoon handle 2 includes an upper spoon handle 21, a connector 4, and a lower spoon handle 22. The connector 4 is located between the upper spoon handle 21 and the lower spoon handle 22, so that the upper spoon handle 21 is connected to the lower spoon handle 22 through the connector 4. The spoon handle adopts a split design and is connected by a connector, which facilitates independent processing and subsequent maintenance of each part. At the same time, the rigidity and connection method of the spoon handle can be adjusted as needed, improving the adaptability and service life of the overall structure.

[0026] The upper gear 31 is rotatably mounted on the end of the upper spoon handle 21, and the lower gear 32 is rotatably mounted on the end of the lower spoon handle 22. Specifically, the ends of the upper spoon handle 21 and the lower spoon handle 22 are the ends that connect to the connector. The gears are respectively mounted on the ends of the spoon handles, making the transmission structure compact and the vibration transmission path short and direct, which is beneficial to improving the sensitivity of vibration response and control accuracy.

[0027] The rotation axis of the upper gear 31 is collinear with the longitudinal axis of the upper spoon handle 21; the rotation axis of the lower gear 32 is collinear with the longitudinal axis of the lower spoon handle 22. Specifically, the longitudinal axes are collinear because the rotation center line of the upper gear and the length direction of the upper spoon handle are completely coincident on the same straight line. The aforementioned length direction is the straight line from the handle's gripping end to the end connecting to the spoon head, which is the most important extension direction of the overall structure. The collinearity of the gear axis and the spoon handle axis ensures that the direction of the driving force transmission is consistent with the direction of the spoon handle.

[0028] The diameters of the upper gear 31 and the lower gear 32 are 1.1 to 2 times the width of the spoon handle 2. The gear diameters are in a reasonable proportion to the width of the spoon handle, making it easy to hold and operate.

[0029] Connector 4 is a sheet-like structure. Both ends of connector 4 have a first shaft hole and a second shaft hole, respectively. The ends of the upper spoon handle 21 and the lower spoon handle 22 are inserted into the first shaft hole and the second shaft hole, respectively. Specifically, the sheet-like structure of connector 4 can be metal, plastic, or a composite structure. The sheet-like connection structure is simple and easy to process. It achieves a reliable connection of the spoon handles through shaft hole insertion, making assembly easy and the connection stable. This facilitates the effective transmission of vibration while reducing processing costs.

[0030] The second shaft hole of connector 4 is 11cm-5cm away from the spoon head. The connector is positioned close to the spoon head, so that the point of action of the vibration structure is close to the sample holding part, resulting in small vibration torque and rapid response, which is conducive to realizing the vibration of the spoon head and thus more precisely controlling the sample addition process.

[0031] The spoon head 1 is an open, arc-shaped opening, and the central axes of the spoon head 1 and the spoon handle 2 are aligned. Specifically, the open, arc-shaped opening of the spoon head refers to its large opening, which facilitates sample retrieval. The arc shape refers to the smooth, concave curved surface of the sample-containing body, similar to a partially spherical or cylindrical surface. This characteristic facilitates the concentration and sliding of the sample towards the opening under vibration. The open, arc-shaped design of the spoon head, along with its coaxial arrangement with the spoon handle, not only facilitates sample retrieval and pouring but also ensures that the vibration transmission direction is consistent with the sample flow direction, promoting uniform sample distribution and further enhancing the controllability of weighing.

[0032] According to another embodiment of the present invention, a gear-vibrating sampling spoon is provided, including a spoon head 1, a spoon handle 2, and a vibration structure 3 disposed on the spoon handle 2. When driven, the vibration structure 3 causes the spoon head 1 to vibrate. The spoon handle 2 is provided with a through groove, and the vibration structure 3 is installed in the through groove. The other parts of this embodiment are the same as those of the above embodiments, and will not be described again.

[0033] Optionally, the through groove is located in the middle of the spoon handle 2 or near the connection area between the upper spoon handle 21 and the lower spoon handle 22. At least part or all of the teeth of the vibration structure 3, i.e., the upper gear 31 and the lower gear 32, are disposed within this through groove, with the gear axis still collinear with the longitudinal axis of the spoon handle 2. The through groove is an opening penetrating both sides of the spoon handle, its shape and size adapted to the installation and rotation of the gears. The upper gear 31 and the lower gear 32 are mounted between the two sides of the through groove via a rotating shaft, with their meshing portion located within the cavity of the through groove. This design integrates the vibration structure within the through groove of the spoon handle, making the overall structure of the medicine spoon more streamlined and integrated. The through groove design enhances the overall rigidity and torsional stability of the upper and lower spoon handles in the connection area, helping to transmit vibration energy more efficiently from the upper spoon handle to the lower spoon handle and the spoon head, reducing unnecessary energy dissipation, and making vibration control more precise.

[0034] This application discloses a gear-driven vibrating sampling spoon. By controlling the force and frequency of gear rotation, the amplitude and frequency of sample vibration in the spoon head are controlled, thus solving the problem of low weighing efficiency caused by relying on wrist shaking during current weighing methods, which easily leads to over-filling or excessively slow weighing. This application involves simple components that do not require complex electric control parts, is inexpensive, and can meet the needs of most laboratories.

Furthermore, other steps, measures, and solutions in the various operations, methods, and processes discussed in this application can also be alternated, modified, rearranged, decomposed, combined, or deleted. Furthermore, steps, measures, and solutions in the prior art that are similar to those disclosed in this application can also be alternated, modified, rearranged, decomposed, combined, or deleted.

[0036] The above description is only a partial embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
