Description

Technical Field

[0001] The utility model relates to the technical field of microwave digestion instruments, in particular to an inner tank cleaning device of a microwave digestion instrument. Background Art

[0002] Microwave digestion technology uses the penetrating and reactive activation capabilities of microwaves to heat reagents and samples in sealed containers, which can increase the pressure in the sample preparation container and raise the reaction temperature, thereby greatly increasing the reaction rate and shortening the sample preparation time.

[0003] When the microwave digester is used to digest pesticide products, the mounting hole has a fixed aperture, so the mounting hole can only accommodate one specification of the inner tank of the microwave digester pesticide product, and cannot adapt to the inner tanks of microwave digester of different coarse and fine specifications. As a result, the inner tanks of the microwave digester pesticide products of various coarse and fine specifications cannot be cleaned during use.

[0004] Therefore, we propose a microwave digestion instrument inner tank cleaning device to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a cleaning device for the inner tank of a microwave digestion instrument to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a microwave digestion instrument inner tank cleaning device, comprising a body, the inner wall of the body is fixedly connected to a placement seat, the top of the placement seat is fixedly connected to a connection plate, and the top of the connection plate is provided with a placement plate;

[0007] The surface of the placement plate is provided with a plurality of mounting seats, and the inner walls of the mounting seats are fixedly provided with a plurality of placement cavities, and the placement cavities are provided with locking blocks, the placement cavities are fixedly connected with a plurality of springs, and the other ends of the springs are fixedly connected with the locking blocks.

[0008] Preferably, the surface of the locking block is provided with a slope with a certain inclination angle.

[0009] Preferably, friction pads are provided on the surfaces of the locking blocks.

[0010] Preferably, a cross block is fixedly connected to the bottom of the placement plate, and a groove matched with the cross block is opened on the top of the connection plate.

[0011] Preferably, a plurality of rubber foot pads are fixedly connected to the bottom of the body.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When the inner tank of the pesticide product is inserted, multiple locking blocks are squeezed and retracted into the placement cavity. When the inner tank of the pesticide product is inserted to the predetermined position, the spring releases its elasticity to push the locking block and the inner tank of the pesticide product tightly together. At the same time, the friction pad arranged on the surface of the locking block increases the friction, thereby ensuring that the inner tank of the pesticide product is firmly locked and that inner tanks of pesticide products with different diameters can be installed and fixed.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a cleaning device for an inner tank of a microwave digestion instrument, comprising a body 1, inner tanks of pesticide products with different diameters can be directly inserted into a mounting seat 5 opened on the surface of a placing plate 4, a plurality of placing cavities 6 are opened on the inner wall of the mounting seat 5, a locking block 7 arranged in the placing cavity 6 touches the inserted inner tank of the pesticide product, and a slope with a certain inclination angle is arranged on the surface of the locking block 7, a plurality of locking blocks 7 form an insertion opening which is wide at the top and narrow at the bottom, and the inner tank of the pesticide product squeezes the plurality of locking blocks 7 to retract into the placing cavity 6 when inserted, and when the inner tank of the pesticide product is inserted to a predetermined position, the spring 8 releases its elasticity to push the locking block 7 to press against the inner tank of the pesticide product, and a friction pad 9 arranged on the surface of the locking block 7 increases friction, thereby ensuring that the inner tank of the pesticide product is firmly locked, and ensuring that inner tanks of pesticide products with different diameters can be installed and fixed.

[0021] For details, please refer to Figure 1-4 The placement seat 2 supports the connecting plate 3, and the placement plate 4 is movably connected to the connecting plate 3 through a cross block 10 fixedly connected at the bottom and a groove opened on the surface of the connecting plate 3, so that the placement plate 4 can be taken out and the inner tank of the pesticide product can be operated. The rubber foot pad 11 ensures the stability of the body 1 on the table.

[0022] Working principle: Pesticide product inner tanks with different diameters can be directly inserted into the mounting seat 5 opened on the surface of the placement plate 4. The inner wall of the mounting seat 5 is provided with multiple placement cavities 6. The locking block 7 arranged in the placement cavity 6 touches the inserted pesticide product inner tank. At the same time, the surface of the locking block 7 is provided with a slope at a certain inclination angle. The multiple locking blocks 7 form an insertion opening that is wide at the top and narrow at the bottom. When the pesticide product inner tank is inserted, the multiple locking blocks 7 are squeezed and retracted into the placement cavity 6. When the pesticide product inner tank is inserted to the predetermined position, the spring 8 releases its elasticity to push the locking block 7 and the pesticide product inner tank tightly. At the same time, the friction pad 9 arranged on the surface of the locking block 7 increases friction to ensure that the pesticide product inner tank is firmly locked. The invention can ensure that inner tanks of pesticide products of various diameters can be installed and fixed. The placement seat 2 supports the connecting plate 3, and the placement plate 4 is movably connected to the connecting plate 3 through a cross block 10 fixedly connected at the bottom and a groove on the surface of the connecting plate 3, so that the placement plate 4 can be taken out and the inner tank of the pesticide product can be operated. The rubber foot pad 11 ensures the stability of the body 1 on the table, and solves the problem that the mounting hole can only be installed with one specification of microwave digestion instrument pesticide product inner tank due to the inconvenience of the fixed aperture of the mounting hole, and cannot adapt to microwave digestion instrument inner tanks of different coarse and fine specifications, resulting in the inability to clean microwave digestion instrument pesticide product inner tanks of various coarse and fine specifications during use.
