The utility model provides a store up rice device, it can be used for storing such as rice, the graininess edible material of beans etc.. However, it can be understood that the rice storage device according to the present invention can also store fruits or vegetables, etc. in the accommodating space. Therefore, the rice storage device may also be referred to as food storage device.

The following describes the rice storage device in detail with reference to the attached drawings.

Accommodating unit

According to the utility model discloses, store up rice device is including the accommodation unit who has accommodation space to store above-mentioned edible material. Fig. 1 and 2 show a housing bin 10 as one example of a housing unit.

The accommodating chamber 10 includes a chamber body 11 and a chamber cover 12. The cartridge body 11 is generally configured in the shape of a rounded rectangular parallelepiped having a space inside and forming an opening at the top communicating with the inside space. A bin cover 12 is detachably provided on the top of the bin body 11 to close the opening. In addition, as shown in fig. 2, the housing 10 further includes a movable cover 13. The movable cover 13 is movably disposed in the up-down direction with respect to the bin body 11, and the edge of the movable cover 13 abuts against the inner side wall surface of the bin body 11. Thereby, the movable cover 13 and the bin 11 form an accommodating space 14 therebetween. Exemplarily, the receiving space 14 may be provided with a larger volume such that it may store 5-10kg of food material.

According to the present invention, the movable lid 13 is applied with a downward biasing force. Therefore, it has a tendency to move downward. When the receiving space 14 stores a food material, the movable lid 13 is pressed against the food material such that most of the space of the receiving space 14 is occupied by the food material. In contrast, the space occupied by air is small. As the food material in the receiving space 14 is continuously taken out, the movable lid 13 gradually moves downward and is always pressed against the food material. In other words, the volume of the accommodating space 14 is variable, and the space occupied by air therein is always small. Therefore, the air quantity in the accommodating space 14 is small, the respiration of the food material can be weakened, adverse effects of the air on the oxidation of the food material and the like can be reduced, and long-term preservation of the food material is facilitated.

Preferably, as shown in fig. 2, the movable cover 13 is provided with a sealing ring 133 along the circumferential direction. The movable cover 13 abuts against the inner side wall surface of the bin body 11 through a seal ring 133. Thereby, the movable cover 13 and the bin 11 are sealed, and air is prevented from entering the accommodating space 14 through a gap between the movable cover and the bin.

In order to enhance the sealing performance, the packing 133 may be preferably provided with a deformation portion 134 protruding outward in the lateral direction. When the movable cover 13 moves relative to the cartridge body 11, the deformation portion 134 is pressed by the two to deform along with the relative movement and always fill the gap between the two. Thus, even if the movable lid 13 moves relatively with respect to the cartridge body 11, the seal is always maintained between the two. Further preferably, a plurality of the deformed portions 134 may be provided at intervals in the moving direction to further enhance the sealing effect.

In addition, as an alternative embodiment, an O-ring may be used instead of the seal ring 133. Preferably, the O-ring seal may be provided in plurality at intervals in the moving direction.

As the movable cover 13 is gradually moved downward, the volume of the accommodating space 14 is gradually reduced. If the air therein cannot be discharged in time, the air pressure in the accommodating space 14 becomes greater. With a constant biasing force, the resultant force to which the movable lid 13 is subjected is gradually reduced, making it increasingly difficult to move it downward. Even if the resultant force becomes zero, the movable cover 13 cannot move downward.

To avoid this, the accommodating space 14 communicates with the external environment (i.e. the external environment relative to the accommodating space 14, which may be the external atmosphere, may be another space in the bin 11, or any environment in which the rice storage device 1 is located, etc.) through the one-way valve 132 which opens towards the outside. When the movable lid 13 compresses the air in the accommodating space 14 to make the air pressure therein greater than the air pressure of the external environment, the check valve 132 automatically opens to discharge the air in the accommodating space 14, so that the air pressure inside and outside is balanced. The downward movement of the movable cover 13 is not affected by the air pressure in the accommodating space 14. And, as the movable cover 13 is continuously moved downwards, the amount of air in the accommodating space 14 is smaller and smaller, which is beneficial to long-term storage of food materials.

Preferably, as shown in fig. 2, a check valve 132 is provided on the movable cover 13. Thereby keeping the one-way valve 132 open and preventing food particles or debris from entering therein and causing clogging. As an alternative embodiment, the one-way valve 132 may be disposed in other locations, such as at the bottom of the cartridge body 11. A filter may preferably be provided on the check valve 132.

In the embodiment shown in fig. 2, the gravity G of the movable lid 13 itself may be utilized as a biasing force to bias it downward. It will be appreciated that, in order to ensure the biasing effect, the weight G of the mobile cover 13 needs to satisfy: g is more than or equal to P S + f. Wherein, P is the pressure intensity in the accommodating space 14, S is the area of the cross section of the accommodating space 14, and f is the friction force between the movable cover 13 and the bin body 11. As a result, the resultant force applied to the movable lid 13 is directed downward, and tends to move downward.

Alternatively, a biasing member may be provided to apply a downward biasing force to the movable cover. To ensure a biasing effect thereon.

As shown in fig. 4, a rice storage device 2 according to another embodiment of the present invention is provided with a biasing member 17'. The biasing member 17 'is connected to the movable lid 13' and applies a downward biasing force thereto. Preferably, the biasing member 17 'may be configured as a spring, and an elastic force applied to the movable cover 13' by the spring is used as the biasing force. Preferably, the biasing member 17 'is disposed above the movable cover 13'. As shown in fig. 4, the upper end of the spring abuts against the lid 12 'and the lower end abuts against the movable lid 13'. It will be appreciated that the spring is now under compression to exert a downward spring force on the flap 13'.

Preferably, in order to ensure the biasing effect, the elastic force F exerted by the biasing member 17 'on the movable cover 13' needs to satisfy: f + G is more than or equal to P S + F. Wherein G is the gravity of the movable cover 13 ', P is the pressure in the accommodating space 14 ', S is the area of the cross section of the accommodating space 14 ', and f is the friction between the movable cover 13 ' and the bin body 11 '. The resultant force received by the movable lid 13' is thus directed downward, which tends to move downward.

Returning again to fig. 2, preferably, the upper surface of the movable lid 13 is provided with a handle 131. After the food material in the accommodating space 14 is used up, the user can detach the bin cover 12, and manually lift the movable cover 13 upwards to overcome the bias force by gripping the handle 131 to take out the movable cover from the bin body 11, so as to add the food material into the accommodating space 14, which is convenient for operation.

The bottom of the bin body 11 is provided with a discharge hole 15 communicated with the accommodating space 14. The food material stored in the accommodating space 14 can automatically flow out of the discharge hole 15 under the action of gravity, so that the food material is convenient for a user to take. Therefore, the rice storage device 1 according to the present invention is particularly suitable for storing granular food materials having fluidity such as rice, beans, and the like. Preferably, the bottom of the cartridge body 11 is configured as an inverted cone. In the present embodiment, the bottom of the cartridge body 11 is generally configured in the configuration of a rectangular pyramid. The discharge port 15 is provided at the top end of the reverse taper (i.e., at the lowest position of the cartridge body 11). Therefore, the bottom of the bin body 11 has a slope, so that food material residue can be avoided. With discharge gate 15 setting in the bottom of storehouse body 11, can avoid operating movable cover 13 when getting the material, be favorable to accommodating space 14's volume to change with the quantity of the edible material of storing wherein unanimously.

Furthermore, the rice storage device 1 comprises a base 20. The receiving container 10 is constructed in a separate structure from the base 20 and is detachably coupled to the base 20. The detachable arrangement mode allows a user to detach and clean the accommodating bin 10, so that the inside of the accommodating bin is kept in a clean and sanitary environment, and long-time storage of food materials is facilitated.

Preferably, one of the bin 10 and the base 20 can be provided with a detent, and the other with a catch. When the accommodating bin 10 is mounted on the base 20, the buckle is engaged with the detent, so that the two are locked. As shown in fig. 3, in the present embodiment, the accommodating chamber 10 is provided with a detent (not shown), and the base 20 is provided with a catch 114. Of course, as an alternative embodiment, the cartridge 10 and the base 20 may be locked by means of fastening means such as screws.

In order to conveniently and smoothly take out the food material from the accommodating space 14, the rice storage device 1 according to the present invention further comprises a material taking unit 40. As shown in fig. 2 and 3, the material taking unit 40 is disposed in the base 20 below the discharge port 15 of the accommodating space 14, and has a material taking chamber 43 and a material taking port (not shown). Wherein the material taking cavity 43 is movable between a first position communicating with the discharge port 15 of the accommodating space 14 and a second position communicating with the material taking port. In the first position, the material taking chamber 43 is able to receive a predetermined amount of food material from the outlet 15. When the material taking chamber 43 is moved from the first position to the second position, the received predetermined amount of food material may be taken out through the material taking opening.

Preferably, get the material mouth and set up in the below of getting material chamber 43, can utilize gravity to make when the two communicate get the edible material in the material chamber 43 and fall automatically, convenience of customers takes.

Preferably, as shown in fig. 2, the rice storage device 1 further comprises a material receiving box 60 disposed below the material taking port. The magazine 60 is removably disposed in the base 20. After the material taking operation is completed by the material taking unit 40, the user may collect the taken-out material from the material receiving box 60.

In addition, in order to ensure sealing of the accommodating space 14 from air entering therein, the taking unit 40 further includes a sealing member (not shown). The sealing member is movable between a sealing position sealing the material withdrawal opening and an opening position unsealing the material withdrawal opening. Moreover, the material taking unit 40 is configured such that when the material taking cavity 43 is located at the second position and is communicated with the material taking port, the sealing member is located at the open position, so that the user can take out the food material conveniently; and when the material taking cavity 43 is located at a position other than the second position, the sealing member is located at a sealing position to seal the material taking port. Thus, when the food materials do not need to be taken out, although the accommodating space 14 is communicated with the material taking unit 40 through the discharge hole 15, the accommodating space 14 is kept sealed relative to the outside, and the accommodating space 14 is ensured to form an independent space to keep a negative pressure state.
