[0002] Chinese patent document CN220350257U discloses a sample collection device for forestry survey and planning, which relates to the field of sample collection devices and includes a collection box. Two partitions are provided inside the collection box to separate the collection box into three drawer slots. The device provides circulating air for the samples in the device by arranging air ducts and cooling fans, which can keep the samples warm in all aspects and prevent the samples from deteriorating and affecting the collection effect. The drawer device is arranged to classify and store the collected samples, and it is also convenient to take and put the samples when storing and retrieving the samples. The baffle is arranged to limit the drawer device to prevent the drawer device from sliding out during the movement of the collection box and causing damage to the samples. The support device is arranged to lift the device upward, so as to facilitate the staff to take and put the samples inside the collection box during operation, and solves the problem that the storage slot of the existing device cannot be pulled out and the samples are not easy to be taken from the above device; however, this design has the following defects: when it is necessary to take the sample bottle, the drawer of the collection box is pulled out and opened, so that the cold air inside the collection box will quickly escape, causing the temperature inside the collection box to rise, and it takes a certain amount of time to return to the required temperature. The escape of the cold air and the deep cooling again will increase energy consumption. In order to solve the above problems, a sample collection device is proposed. Utility Model Content
