The freshness of the particulate matter 600 can be substantially comprised of stale, first freshness, and second freshness, wherein the freshness of the particulate matter 600 corresponding to the second freshness is higher than the freshness of the particulate matter 600 corresponding to the first freshness. Correspondingly, the display unit 400 may display characters, such as "not fresh", "edible", and "fresh", and may also display colors, such as "red", "gray", and "green". Wherein red can indicate that the particulate matter 600 is stale, gray can indicate that the particulate matter 600 is at a first freshness, and green can indicate that the particulate matter 600 is at a second freshness. It is to be understood that the freshness of the particulate matter 600 can be further subdivided, including, for example, stale, first freshness, second freshness, third freshness … …, and the like, and is not particularly limited herein.

Referring to fig. 1, in some embodiments, a nursing unit 500 of the storage device 100 of the present invention includes a vacuum pump 501 connected to the storage space via a suction line 510, and configured to evacuate the storage space to form a vacuum atmosphere in the storage space that facilitates preservation of the particulate matter 600. Through to storing space evacuation, can improve storing space's vacuum, and then the retention time of the new freshness of extension particulate matter 600. Fig. 3 is a schematic structural view of a storage device 100 according to another embodiment of the present invention. In other embodiments, the nursing unit 500 of the storage device 100 according to the embodiment of the present invention includes: the inert gas tank 502 is connected with the storage space through a gas pipeline 520 and is configured to fill inert gas into the storage space so as to form a gas atmosphere favorable for keeping the particulate matters 600 fresh in the storage space. An on-off valve 530 is provided on the gas line 520 to control the flow of the inert gas.
Determining the freshness of the particulate matter 600 based on the transmittance of the control unit 300 of the storage device 100 of the embodiment of the present invention may include various implementations. For example, the measured transmittance is compared to a preset value to determine the freshness of the particulate matter 600. As another example, multiple measured transmittances can be compared to determine freshness of the particulate matter 600. As another example, the freshness of the particulate matter 600 can be determined based on a trend of change in the transmittance measured multiple times. The control method of the storage device 100 according to the embodiment of the present invention will be described in detail herein by taking the example of comparing the transmittance with a predetermined value to determine the freshness of the particulate matter 600.
In some embodiments, in the control method of the storage device 100 according to the embodiment of the present invention, the step of determining the freshness of the particulate matter 600 based on the transmittance of light includes:
judging whether the transmittance is less than a first preset transmittance threshold value;
if so, the freshness of the particulate matter 600 is determined to be stale.
The control method of the storage device 100 according to the embodiment of the present invention first determines whether the transmittance is less than a first predetermined transmittance threshold, which considers that the freshness of the particulate matter 600 is in a long-term edible state before the freshness reaches the freshness, and that the freshness is in a state of being fresh or edible, and that the freshness of the particulate matter 600 reaches the freshness, the particulate matter 600 is considered to be in a state of being deteriorated in quality and being not suitable for long-term eating or even being inedible, so as to avoid affecting the physical health of the user. Different types of particles 600 respectively have corresponding first preset light transmission thresholds, and the names of the types of the particles 600 and the corresponding first preset light transmission thresholds are stored in the sensor 202 or the control unit 300. The user selects the type name of the particulate matter 600 after placing the particulate matter 600 into the storage device 100, thereby determining the first preset light transmission threshold value at that time. Or, a type detection unit is further disposed in the storage device 100, and is configured to identify the type of the particulate matter 600 placed in the storage device 100 through image recognition or other prior art, and then determine a corresponding first preset light transmittance threshold value based on the identification result. The first preset light transmittance threshold may be obtained by, during manufacturing of the storage device 100, placing completely stale particulate matter 600 (for example, particulate matter 600 with a shelf life being over) into the detection unit 200 to obtain a measured illumination intensity, calculating a ratio of the measured illumination intensity to an illumination intensity of light measured by the sensor 202 when no particulate matter 600 is placed, and using the ratio as the first preset light transmittance threshold, or setting the first preset light transmittance threshold to be slightly higher than the ratio, or further selecting a plurality of different brands of the same type of particulate matter 600, repeating the foregoing steps for a plurality of times, and averaging the obtained ratios to use the average value as the first preset light transmittance threshold, and the like.
In the control method of the storage device 100 according to the embodiment of the present invention, when it is determined that the freshness of the particulate matter 600 is not fresh, the storage device 100 is controlled to send out the reminding message. The reminding message may be sent by setting the display unit 400 to a light flashing mode, or by setting a sound-emitting unit on the storage device 100 to send a reminding sound. By setting the storage device 100 to send out the reminding information when the particulate matter 600 is not fresh, the user can be reminded to process the non-fresh particulate matter 600 in time.
In the control method of the storage device 100 according to the embodiment of the present invention, when the transmittance is greater than or equal to the first preset transmittance threshold, the nursing unit 500 is controlled to act, so as to form a vacuum atmosphere or a gas atmosphere in the storage space, which is favorable for keeping the particulate matter 600 fresh. Through control nursing unit 500 action when transmittance is more than or equal to first preset printing opacity threshold value in order to form the vacuum atmosphere or the gaseous atmosphere that do benefit to the particulate matter 600 fresh-keeping in storing space, can prolong the freshness retention time of particulate matter 600. When nursing unit 500 includes vacuum pump 501, when the transmittance is greater than or equal to first preset light transmission threshold value, control vacuum pump 501 and open, to the storing space evacuation to form the vacuum atmosphere that does benefit to particulate matter 600 fresh-keeping in the storing space. When the nursing unit 500 comprises the inert gas tank 502, when the light transmittance is greater than or equal to the first preset light transmittance threshold value, the inert gas tank 502 is controlled to be opened, and inert gas is filled into the storage space, so that a gas atmosphere favorable for keeping the particulate matters 600 fresh is formed in the storage space.
In the control method of the storage device 100 according to the embodiment of the present invention, when the transmittance is greater than or equal to the first preset transmittance threshold, it is determined whether the transmittance is less than a second preset transmittance threshold, where the second preset transmittance threshold is greater than the first preset transmittance threshold;
if so, determining the freshness of the particulate matter 600 to be a first freshness;
if not, the freshness of the particulate matter 600 is determined to be a second freshness, wherein the second freshness is higher than the first freshness.
According to the control method of the storage device 100, the first preset light transmission threshold value and the second preset light transmission threshold value are set, so that the freshness of the particles 600 is divided into three levels, namely, freshness, the first freshness and the second freshness, and the particles 600 have three qualities of freshness, edibility and freshness correspondingly, so that the confirmation of the freshness of the particles 600 is more consistent with the actual requirements of users, meanwhile, the control steps are not too complicated, and the freshness judgment speed is increased. As mentioned above, taking rice as an example, the first predetermined light transmission threshold may be 0.01-0.1, such as 0.05, 0.08, 0.1, and the second predetermined light transmission threshold may be 0.3-0.4, such as 0.3, 0.35, 0.4.
In some embodiments, in the control method of the storage device 100 according to the embodiment of the present invention, when the freshness of the particulate matter 600 is determined to be the first freshness, the nursing unit 500 is controlled to operate for the first preset time period at first preset intervals; when the freshness of the particulate matter 600 is determined to be a second freshness, controlling the nursing unit 500 to operate for a first preset time period at intervals of a second preset interval; wherein the second preset interval time is longer than the first preset interval time. The parameters of the actions of the care unit 500 may include a length of run time, an interval time, etc., and the run time and/or the interval time of the care unit 500 may be the same or different for different freshness degrees. In the invention, the operation time of the nursing unit 500 corresponding to the second freshness and the operation time of the nursing unit 500 corresponding to the first freshness are both set as the first preset time, the interval time of the nursing unit 500 corresponding to the second freshness adopts the second preset interval time, and the interval time of the nursing unit 500 corresponding to the first freshness adopts the first preset interval time, so that the control logic is matched with the current freshness of the particles 600, and the method is simple and easy to realize. The first preset time period of the nursing unit 500 may be 5-20min, for example 5min, 7min, 10min, 20 min; the first predetermined interval may be 3-5 days, e.g., 3 days, 4 days, 5 days; the second predetermined interval may be 5-7 days, such as 5.5 days, 6 days, 7 days. For the vacuum pump 501, the first preset time period is the starting time of the vacuum pump 501. For example, the vacuum pump 501 is controlled to operate for 10min every 3 days when the freshness of the particulate matter 600 is determined to be the first freshness degree, and the vacuum pump 501 is controlled to operate for 10min every 7 days when the freshness of the particulate matter 600 is determined to be the second freshness degree. For the inert gas tank 502, the first preset time period may be determined by dividing the amount of the inert gas filled into the storage device 100 by the inflation speed of the inert gas tank 502 by 10% -20% of the total volume of the storage space, for example, assuming that the total volume of the storage space is 2000mL, the inflation speed is 20mL/min, and the first preset time period is 10min-20 min. For example, the inert gas tank 502 is controlled to be opened for 10min every 3 days when the freshness of the particulate matter 600 is determined to be the first freshness, and the inert gas tank 502 is controlled to be opened for 10min every 7 days when the freshness of the particulate matter 600 is determined to be the second freshness.
