[0002] With the improvement of people's living standards and the change of consumption concepts, the pursuit of food freshness and nutritional value is increasing. The main function of food storage containers is to extend the shelf life of food by creating an environment conducive to food preservation, reducing the contact between food and oxygen, and inhibiting the growth of microorganisms and the oxidation process of food. They are widely used in homes, restaurants, supermarkets and other places for storing various foods such as fruits and vegetables, meat, seafood, and cooked food.
[0003] However, most current food storage containers only have storage functions. When the humidity inside the container is too high or the oxygen concentration is insufficient, it will reduce the freshness of fruits and vegetables, shorten the freshness period, and cause more trouble for the storage of fruits and vegetables. To address this issue, the applicant proposes a breathable and adjustable fruit and vegetable storage container. Utility Model Content

An oxygen concentration sensor 13 and a humidity sensor 14 are respectively connected to the bottom of the fixing box 12.
[0034] As can be seen from the above, during use, the first box 21 can slide up and down along the outer periphery of the second box 22, which can change the internal storage space. It can be easily adjusted to a suitable storage space according to the quantity of fruits and vegetables to be stored, thus improving the applicability. By closing the protective cover 11, the fruits and vegetables stored inside can be easily protected. The oxygen concentration sensor 13 can monitor the oxygen content inside the storage component 2 in real time, and the humidity sensor 14 can easily monitor the humidity inside the storage component 2 in real time. By pushing the baffle 15 to move, the holes on the baffle 15 can be misaligned with the vent holes 110. Through the blocking effect of the baffle 15, the opening and closing degree of the vent holes 110 can be easily controlled. When the humidity inside the storage component 2 is too high or the oxygen concentration is insufficient, the opening and closing degree of the vent holes 110 will be automatically adjusted to control the gas exchange rate inside and outside the storage component 2, thereby increasing the air permeability. Conversely, the air permeability will be reduced to maintain the best preservation state and effectively extend the preservation effect of fruits and vegetables.
[0035] Depend on Figure 6 It can be seen that the inner wall of the second box 22 is fixedly installed with symmetrically distributed support frames 24, and a drain plate 23 is placed on the top of the support frame 24.
[0036] As can be seen from the above, by placing the draining board 23 on the support frame 24, the draining board 23 can be easily supported, so that there is a certain space between the draining board 23 and the second box 22. The water stains remaining on the fruits and vegetables can be drained through the draining board 23, avoiding the fruits and vegetables from being soaked and ruined due to prolonged contact with water. At the same time, the draining board 23 can be disassembled and removed for easy cleaning.
[0037] Specifically, refer to Figure 1 and Figure 6As shown, the first box 21 and the second box 22 are fixed together by a fixing knob 26, and the front end of the second box 22 is provided with a drain outlet 25.
[0038] As can be seen from the above, the first box 21 can be easily moved up and down and then fixed by the fixing knob 26, so as to prevent the first box 21 from sliding accidentally. The drain outlet 25 can easily drain the water stains, so as to prevent them from accumulating in the box and affecting the storage of fruits and vegetables.
[0039] Specifically, refer to Figure 1 , Figure 2 and Figure 5 As shown, a latching bracket 18 is hinged to the front end of the protective cover 11, and a latching strip 27 for latching the latching bracket 18 is fixedly installed at the front end of the second box 22.
[0040] As can be seen from the above, by flipping the locking frame 18 downwards, the locking frame 18 and the locking strip 27 can be easily locked together, which can facilitate the fixing of the protective cover 11.
[0041] Example 2:
[0042] refer to Figure 2 and Figure 3 As shown, a storage battery 111 is fixedly installed inside the fixed box 12, and a control panel 19 is fixedly installed on the top of the protective cover 11.
[0043] As can be seen from the above, the storage battery 111 can store electrical energy to power electrical components, and the control panel 19 can be used to easily set the monitoring values of the oxygen concentration sensor 13 and the humidity sensor 14.
[0044] refer to Figure 2 As shown, an electric push rod 17 is fixedly connected between the shield 15 and the protective cover 11, and a sliding frame 16 for sliding the shield 15 is fixedly installed on the inner wall of the protective cover 11.
[0045] As can be seen from the above, when the humidity is too high or the oxygen concentration is insufficient, the electric push rod 17 can be triggered to extend and retract, which can conveniently provide power to the baffle 15 and automatically drive the baffle 15 to move, thereby realizing automatic control of the opening and closing degree of the vent 110.
[0046] refer to Figure 5 As shown, the protective cover 11 has scale lines 114 engraved on both sides of its surface, and the top of the push handle 112 is fixedly equipped with a pointer 113 corresponding to the scale lines 114.
[0047] As can be seen from the above, by using the push handle 112, the baffle 15 can be moved manually. By observing the value on the scale line 114 corresponding to the pointer 113, the opening and closing degree of the vent 110 can be controlled manually and accurately. It can be operated manually even without power, which brings more convenience to the user.
[0048] 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.
