[0030] 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.
[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0032] Please see Figure 1-8 This utility model provides a technical solution:
[0033] A small food sampler includes a sampling tube 1, a sealing strip 2 fixedly connected to one side of the sampling tube 1, a connecting assembly 3 fixedly connected to the bottom end of the sampling tube 1, a rotating sampling assembly 4 rotatably connected to the inner side of the sampling tube 1, a venting assembly 5 fixedly connected to the inner side of the connecting assembly 3, a rotating assembly 6 rotatably connected to the outer side of the venting assembly 5, and an airbag assembly 7 fixedly connected to the lower end of the venting assembly 5. The connecting assembly 3 includes a connecting ring 31, an inter-ring hole 32 formed on the inner side of the connecting ring 31, an annular groove 33 formed at the bottom end of the connecting ring 31, and a slot 34 formed on the inner side of the connecting ring 31. The rotating sampling assembly 4 includes a rotating sampling plate 41, a supporting connecting magnet 42 fixedly connected to the bottom end of the rotating sampling plate 41, and a fixed support connecting magnet 42 on one side. A rotating short rod 43 is fixedly connected, and a limit hole 44 is opened on the inner side of the rotating short rod 43. The ventilation assembly 5 includes a filter plate 51, a support column 52 is fixedly connected to the inner side of the filter plate 51, a hollow column 53 is fixedly connected to the lower end of the support column 52, a shaft column 54 is fixedly connected to the upper end of the hollow column 53, a bottom hole 55 is opened at the bottom end of the hollow column 53, a ventilation tube 56 is installed inside the hollow column 53, and a valve 57 is fixedly connected to the inner side of the ventilation tube 56. The airbag assembly 7 includes an upper fixing plate 71, a rubber tube 72 is fixedly connected to the inner side of the upper fixing plate 71, an airbag ball 73 is fixedly connected to the bottom end of the upper fixing plate 71, a support strip 74 is fixedly connected to the bottom end of the upper fixing plate 71, and a lower fixing plate 75 is fixedly connected to the bottom end of the support strip 74.
[0034] As a further implementation of this scheme, the center point of the upper end face of the connecting ring 31 coincides with the center point of the bottom end face of the skewer 1, the upper end face of the connecting ring 31 and the bottom end face of the supporting connecting magnetic block 42 are on the same horizontal plane, the inner side of the inter-ring hole 32 is in close contact with the outer side of the hollow column 53, and the vent pipe 56 is set above the connecting ring 31. The design of the connecting ring 31 and the central axis of the skewer 1 coinciding helps to ensure the coaxiality between the two and avoid uneven force due to eccentricity. The vent pipe 56 being set above the connecting ring 31 can ensure that the gas can be discharged smoothly without being blocked by the connecting ring 31.
[0035] As a further implementation of this solution, the included angle between the rotating short rod 43 and the shaft column 54 is 90°, the inner side of the limiting hole 44 is in contact with the outer side of the shaft column 54, and the bottom end face of the rotating short rod 43 is on the same horizontal plane as the upper end face of the hollow column 53. This setting ensures that while the rotating short rod 43 drives the supporting connecting magnetic block 42 to rotate within the predetermined trajectory, it also ensures the stability of the rotation.
[0036] As a further implementation of this scheme, a gap is provided between the outer side of the filter disc 51 and the inner side of the rotating sample plate 41. The support column 52 and the shaft column 54 are parallel to each other, and the height of the support column 52 is 1.3 times the height of the shaft column 54. A hollow column 53 is fixedly connected to the outer side of the vent pipe 56. The valve 57 is arc-shaped, and several valves 57 are provided. The multiple valves 57 are evenly and equidistantly distributed in a ring array on the inner side of the vent pipe 56. The gap between the outer side of the filter disc 51 and the rotating sample plate 41 provides space for the movement of the rotating sample plate 41 and avoids collision or friction between the two during movement. The design that the height of the support column 52 is 1.3 times the height of the shaft column 54 can prevent the bottom of the filter disc 51 from contacting other components and meet the space layout requirements. The arc-shaped design of the valve 57 can achieve a good sealing effect when closed to prevent gas backflow or leakage, and can also guide gas flow more smoothly when open, reducing flow resistance.
[0037] As a further implementation of this solution, the rotating assembly 6 includes a rotating disk 61, with a retaining ring 62 fixedly connected to the upper end of the rotating disk 61 and a fixed magnetic block 63 fixedly connected to the upper end of the rotating disk 61. A concentric hole 64 is opened on the inner side of the rotating disk 61, and several rubber strips are fixedly connected to the outer side of the rotating disk 61 in an equidistant distribution. The shape of the fixed magnetic block 63 is exactly the same as the shape of the supporting connecting magnetic block 42, and the two are symmetrically distributed vertically. The diameter of the concentric hole 64 is equal to the diameter of the annular hole 32. The fixed magnetic block 63 is set in the annular groove 33, and the retaining ring 62 is rotatably installed in the retaining groove 34. The rubber strips on the outer side of the rotating disk 61 can enhance the friction coefficient on the outer side of the rotating disk 61 and prevent slippage during rotation. The cooperation between the retaining ring 62 and the retaining groove 34 enables the rotating disk 61 to rotate stably on the connecting ring 31, while preventing the rotating disk 61 from being displaced in the axial direction, thus playing a role in limiting and fixing. The setting of the fixed magnetic block 63 and the supporting connecting magnetic block 42 enables the two to achieve magnetic connection for transmission.
[0038] As a further implementation of this scheme, a portion of the rubber tube 72 is set in the bottom hole 55, with the outer side of the rubber tube 72 closely attached to the inner side of the bottom hole 55. The outer side of the airbag 73 has holes. Several support bars 74 are arranged in a circular array at the bottom end of the upper fixed plate 71. The lower fixed plate 75 and the upper fixed plate 71 have the same projection in the vertical direction. The holes on the outer side of the airbag 73 can realize the functions of ventilation and pressure regulation. The support bars 74, the lower fixed plate 75 and the upper fixed plate 71 jointly bear the pressure when the device is used, reducing local stress concentration and preventing excessive deformation of the airbag 73.
[0039] Workflow: During use, hold the airbag assembly 7 and insert the snipping tube 1 into the food packaging to be sampled. Then, rotate the rotating disk 61. The rubber strip on the outside of the rotating disk 61 provides anti-slip properties and facilitates rotation. When the rotating disk 61 rotates, it drives the fixed magnetic block 63 to rotate. The magnetic attraction between the fixed magnetic block 63 and the supporting magnetic block 42 causes the supporting magnetic block 42 to rotate. After the supporting magnetic block 42 rotates to a certain angle, a sealed space is formed between the rotating sampling plate 41 fixedly connected to the upper end of the supporting magnetic block 42, the snipping tube 1, and the sealing strip 2. The food entering the space of the snipping tube 1 will be isolated from the outside. At this time, block the hole on the outside of the airbag ball 73 and squeeze the airbag ball 73. The air inside the airbag ball 73 will enter the hollow column 53 through the rubber tube 72 and then enter the ventilation tube 56 from the hollow column 53, affecting the valve 5 located inside the ventilation tube 56. Pressure 7 is generated, causing valve 57 to deform. Air is blown out of valve 57 and into the skewer tube 1. This exerts a force on the food inside the skewer tube 1, causing the food to shake and reduce the gaps between the food items. Due to the arc-shaped structure of valve 57, air can only enter the vent tube 56 from the inside of the hollow column 53 to push open valve 57, and cannot enter the vent tube 56 from the outside of the hollow column 53. This prevents air from entering the vent tube 56 from the skewer tube 1, the rotating skewer plate 41, and the sealing strip 2. The increased air pressure in the space causes the lighter gas to accumulate in the upper part of the space, resulting in food sedimentation. In response, the rotating disk 61 is rotated again, causing the fixed magnetic block 63 to drive the supporting magnetic block 42 and the rotating sampling plate 41 fixedly connected to the supporting magnetic block 42 to rotate. This allows more food to enter the sampling tube 1, ensuring the sampling quantity meets the standard. After removing the sampling tube 1 and emptying the food, the hand blocking the outer hole of the airbag ball 73 is released, allowing the airbag ball 73 to quickly recover its shape. The hole is then blocked again, and the airbag ball 73 is squeezed. This process is repeated while the rotating disk 61 is quickly rotated back and forth, allowing air from the airbag ball 73 and the hollow column 53 to pass through the vent pipe 56 and valve 57 to clean the surface of the support column 52 and the inside of the sampling tube 1, ensuring the cleanliness of the device.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
