[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0023] like Figures 1 to 3 As shown, this embodiment discloses a hygienic food safety sample collector, comprising a sampling rod 1, an operating rod 3 and three sampling boxes 2 arranged in sequence from top to bottom (the number of sampling boxes 2 can also be set to be more), the sampling box 2 comprises a box body and a sealing cover 5, the box body is connected to the sampling rod 1, a vertical movable rod 4 is provided on the top of the sealing cover 5, the movable rod 4 is connected to a horizontal synchronization plate 19, the synchronization plate 19 is slidably sleeved on the sampling rod 1 and fixedly connected to the operating rod 3, a support plate 6 is provided below the synchronization plate 19, the support plate 6 is connected to the synchronization plate 19 through a first spring 7, and the support plate 6 is fixed on the sampling rod 1. By providing at least three sampling boxes 2, it is convenient to quickly collect the upper, middle and lower layers of the liquid sample, and after the sampling is completed, the sampling box 2 is covered by the sealing cover 5, which is not only conducive to preventing the liquid samples of other layers from entering the sampling box 2, but also conducive to preventing the liquid samples in the sampling box 2 from spilling, thereby reducing operational errors, and the sampling operation is convenient and quick. The sealing covers 5 of all sampling boxes 2 are synchronously controlled by the operating rod 3 to achieve rapid opening of all sampling boxes 2. After the sampling is completed, the force on the operating rod 3 is removed, and the first spring 7 rebounds so that the sealing cover 5 automatically covers the box body downward, that is, the sampling box 2 is automatically closed, which reduces the manual operation steps and is convenient and quick.
[0024] The sampling box 2 is provided with a pressing component, which includes a filter plate (preferably a metal filter plate 8), a pressing plate 9, a pressing rod 10, a pressing block 11 and a third spring 12. The filter plate is located inside the box body, the pressing plate is located above the sealing cover 5, and the pressing plate and the sealing cover 5 are connected by the third spring 12. One end of the pressing rod 10 is connected to the pressing block 11, and the other end passes through the sealing cover 5 to connect to the pressing plate 9 located below the sealing cover 5. The sealing cover 5 is slidably sleeved on the pressing rod 10. A plurality of sharp teeth are provided at the lower end of the pressing plate. A faucet 22 is installed on one side of the lower end of the box body of the sampling box 2. When it is necessary to collect juice samples from fruit and vegetable samples, the fruit and vegetable samples are placed in the box body of the sampling box 2, and the fruits and vegetables are supported by the metal filter plate 8. Then, the pressing block 11 is pressed downward, and the pressing block 11 pushes the pressing rod 10 and the pressing plate 9 downward. The pressing plate 9 crushes and pierces the fruits and vegetables through the sharp teeth, thereby facilitating the squeezing of the juice samples from the fruit and vegetable samples through the pressing plate 9, and then the juice samples in the fruits and vegetables are filtered to the bottom of the box body through the metal filter plate 8. By opening the faucet 22, it is convenient to discharge and collect the juice samples for subsequent testing, and it is convenient to extract the juice samples from the fruits and vegetables for sampling. The crushed fruits and vegetables are left on the metal filter plate 8, thereby effectively achieving the effect of solid-liquid separation sampling of fruits and vegetables, and ensuring the practicality of the collector.
[0025] The box body of the sampling box 2 is detachably connected to the sampling rod 1, so that the box body of the sampling box 2 can be removed separately. In the specific structure, the box body of each sampling box 2 is connected to the sampling rod 1 through a positioning clamping assembly, and the positioning clamping assembly includes a mounting plate 13, a groove plate 14, two positioning plates 15, and a second spring 16. The mounting plate 13 is connected to the box body, and the two positioning plates 15 are vertically spaced and opposite and slidably arranged on the mounting plate 13. The second spring 16 is arranged between the two positioning plates 15 and connects the two positioning plates 15. The groove plate 14 is located above the mounting plate 13 and connected to the sampling rod 1. The bottom of the groove plate 14 is provided with a receiving groove, and the upper ends of the two positioning plates 15 are located in the receiving groove. Each positioning plate 15 is provided with a card block 18 on the side facing away from the other positioning plate 15, and the side wall of the receiving groove is provided with a card groove 17 matching the card block 18. Preferably, the upper end of the card block 18 is provided with a chamfer to facilitate the card block 18 to be inserted into the card groove 17, that is, the upper end of the card block 18 is provided with an inclined surface.
[0026] When the box body of the sampling box 2 needs to be removed separately, the two positioning plates 15 are pressed, and the positioning plates 15 will compress the second spring 16. At the same time, the positioning plates 15 will drive the card block 18 to move out of the card slot 17, and then the mounting plate 13 and the positioning plate 15 are pulled down, so that the positioning plate 15 moves out of the receiving slot of the groove plate 14. At this time, the box body can be conveniently taken out separately, which is convenient for subsequent testing or cleaning of the food samples in the box body. If the box body of the sampling box 2 needs to be reinstalled, the upper end of the positioning plate 15 is inserted into the groove plate 14, during this process, the groove plate 14 will push the positioning plate 15 inward along the inclined surface of the card block 18, and the positioning plate 15 will compress the second spring 16 until the upper end of the positioning plate 15 presses against the inner wall of the receiving groove of the groove plate 14, at this time, the card block 18 is aligned with the notch of the card slot 17, and the rebound force of the second spring 16 will drive the card block 18 to be stuck in the card slot 17, so as to facilitate the installation of the box body of the sampling box 2, so as to facilitate the subsequent sampling operation of the upper, middle and lower layers of liquid food through the sampling box 2.
[0027] A first handle 20 is provided at the upper end of the sampling rod 1, and a second handle 21 is provided at the upper end of the operating rod 3. When the food hygienic and safe sampling is performed through the collector, one hand holds the first handle 20, and the other hand holds the second handle 21, and then the sampling box 2 is driven to be inserted into the liquid food through the sampling rod 1 until the three sampling boxes 2 are located at the upper, middle and lower layers of the liquid food, and then the second handle 21 is pulled upwards and the operating rod 3, the synchronous plate 19, the movable rod 4 and the sealing cover 5 are driven upwards until the sealing cover 5 is opened above the sampling box 2, and then the liquid samples of the corresponding layers will enter the sampling box 2, so the three sampling boxes 2 will sample the upper, middle and lower layers of the liquid sample one by one, so as to achieve the effect of sampling three layers at the same time, and the operation is convenient.
[0028] Since the first spring 7 will be stretched when the synchronous plate 19 moves upward, when the sampling box 2 finishes sampling the liquid sample, the second handle 21 is released and the operating rod 3 is no longer pulled up, and then the rebound force of the first spring 7 will drive the synchronous plate 19, the movable rod 4 and the sealing cover 5 to move downward at the same time until the sealing cover 5 covers the upper end of the sampling box 2. In summary, it is not only beneficial to prevent liquid samples at other levels from entering the sampling box 2, but also beneficial to prevent the liquid samples in the sampling box 2 from spilling, thereby reducing operating errors and making the sampling operation convenient and quick.
