Description

Technical Field

[0001] This invention relates to the field of heating and heat preservation equipment, and specifically to a reheating device. Background Technology

[0002] During field training or missions, various types of food need to be heated before consumption. However, limited resources often prevent the use of cooking equipment for hot food processing or keeping fresh food warm, so room-temperature communal meals (vacuum-packed) are typically used. In such cases, the rice steamer equipped on the kitchen vehicle is usually used for heating, or pots are used for boiling. Some manufacturers have developed small reheating steamers, similar in shape to rotomolded boxes, which can use steam for reheating.

[0003] In practical engineering work, the following problems exist:

[0004] I. In existing steam ovens, if there is only one insulation cover, the insulation capacity is poor; if multiple insulation covers are set, they interfere with each other and occupy more space and volume, thus creating a contradiction.

[0005] Second, the existing steamers are round. When the cooking vehicle is moving around in the field, the round steamer cannot be placed stably. If it is set to be square, the round valve cover, which is easy to seal, cannot be used. This creates a contradiction.

[0006] Third, in existing steamers or steam pots, if the internal pressure is high enough, forcibly opening them can easily cause steam burns.

[0007] Fourth, when personnel are performing field missions, they need to avoid steam burns as described in point three in most cases. However, in case of emergency missions, there is not enough time to wait for the steam to dissipate. In this case, under the premise of wearing gloves and other protective equipment, there is a need to turn on the steamer immediately.

[0008] Fifth, the existing telescopic locking structure has a pre-tightening adjustment mechanism. However, the telescopic locking mechanism is generally long, and the corresponding spring is also long. In this case, the rotation adjustment stroke of the pre-tightening adjustment mechanism, such as the nut, is short. If the lengths are mismatched, the adjustment stroke of the nut will be insufficient.

[0009] VI. Existing adjusting springs are prone to wobbling if their stroke is too long, which inevitably leads to friction and wear between them and other components. Summary of the Invention

[0010] To overcome the above problems, the present invention proposes a solution that addresses multiple problems simultaneously.

[0011] The technical solution adopted by this invention to solve its technical problem is: a reheating device, including a box, a cylinder, and an insulation cover, wherein the insulation cover includes a square cover, a top cover, a round cover, a top ring, a baffle cylinder, a baffle ring, a cover plate, a connecting cylinder, a locking module, a steam module, and a handle; the locking module includes a cylinder, a piston, a spring, a constraint ring, a piston rod, an upper baffle rod, a lower baffle rod, a spring seat, a round seat, and a nut; the steam module includes a steam conduit, an exhaust pipe, a safety valve, an exhaust port, a pressure sensor, and an intake pipe;

[0012] The box is square, with a cylindrical body inside. A square cover is hinged to the box, and a round cover is screwed to the cylindrical body. A connecting cylinder is located in the middle of the round cover, and the connecting cylinder passes through the cover of the square cover. A baffle and a retaining ring are connected to the outer wall of the connecting cylinder. The baffle is located above the upper surface of the square cover, and the retaining ring is located below the lower surface of the square cover. A top ring is located on the upper surface of the square cover, and the inner wall of the top cover is threaded to the outer wall of the top ring. A handle is located on the outer wall of the baffle.

[0013] The connecting cylinder is equipped with the cover plate, which includes the safety valve, exhaust port, pressure sensor, and air inlet pipe. The exhaust pipe is fixed to the connecting cylinder and passes sequentially through the bottom surface of the connecting cylinder and the exhaust port. Four steam pipes are connected to the bottom surface of the connecting cylinder. The diameter of the air inlet pipe is larger than the diameter of the exhaust pipe. The inner wall of the top cover is detachably fitted with a cap for the air inlet pipe. After removing the top cover, external steam is introduced into the cylinder through the air inlet pipe and steam pipes. When the steam pressure in the cylinder exceeds the set pressure of the safety valve, the safety valve opens to discharge the steam from the cylinder.

[0014] The locking module is provided on the round cover, and a card plate is provided on the upper surface of the box body. The card plate has a through hole. The piston is slidably arranged in the cylinder body. A spring seat is provided on the right side of the piston. The piston rod is connected to the right side of the spring seat. The round seat is provided on the inner wall of the cylinder body. The round seat has a hemispherical cross section. The left and right ends of the cylinder body are open. The nut is fitted on the right opening of the cylinder body. The nut has a threaded part and a stepped part. The outer wall of the threaded part is threadedly connected to the inner wall of the cylinder body. The piston rod passes through the round seat and is fitted in the nut. The constraint ring is fixedly provided on the outer wall of the cylinder body. The outer wall of the stepped part abuts against the inner wall of the constraint ring. The spring is provided between the spring seat and the threaded part.

[0015] When the steam pressure inside the cylinder is high enough, it pushes the piston to move, causing the piston rod to pass through the through hole, thereby limiting the position of the round cover. The upper stop rod and the lower stop rod are pivotally connected to the end face of the right end of the piston rod. The pivot point of the upper stop rod and the end face is located at one-quarter of the length of the upper stop rod, and the pivot point of the lower stop rod and the end face is located at one-quarter of the length of the lower stop rod.

[0016] Preferably, the connection between the round cap and the cylindrical body is a rotary snap-fit ​​connection.

[0017] Preferably, the right end face of the nut has a groove that is off-center, and the groove cooperates with a corresponding tool to rotate the nut.

[0018] Preferably, the through hole is a strip-shaped hole.

[0019] Preferably, the strip-shaped hole extends laterally.

[0020] Preferably, the left end of the cylinder is located inside the round cover.

[0021] Preferably, a round cap extends from the right end of the cylinder body.

[0022] Preferably, the circular base has a ring structure.

[0023] Preferably, the square cover includes a cover body and cover walls, and the number of cover walls is four.

[0024] Preferably, the four cover walls are provided with transition sections between each other.

[0025] The beneficial effects of this invention are:

[0026] Firstly, regarding the first point raised in the background technology, the insulation cover module is set as a triple insulation cover mode. The nesting of the square cover, round cover, and top cover achieves three layers of insulation, which improves the insulation effect. The nesting also avoids excessive volume.

[0027] Second, regarding the second point raised in the background technology, the square cover is hinged to the steamer, and the round cover is rotated and snapped to the steaming cylinder in the steamer. The round cover is set inside the square cover, and a connecting cylinder is provided on the round cover, extending through the square cover. Baffles and baffle rings are provided above and below the connecting cylinder to fix the square cover and the round cover. A handle is provided on the upper baffle to rotate the round cover to separate or connect it with the steaming cylinder.

[0028] Thirdly, regarding the third point raised in the background technology, a locking structure is provided on the round cover, which cooperates with the card plate provided on the steamer to achieve locking and unlocking. After the piston rod of the locking structure extends into the through hole on the card plate, the round cover cannot be rotated.

[0029] Fourthly, regarding the fourth point raised in the background technology, two rotatable stop levers are provided on the piston rod of the locking structure. The stop levers can rotate to expand the coverage area of ​​the piston rod, thus preventing the piston rod from extending into the through hole on the card plate and avoiding locking; the two stop levers are staggered to avoid mutual stroke interference. When locking occurs, pressing the piston rod to disengage it from the through hole and rotating the two stop levers will prevent locking again.

[0030] Fifth, regarding the fifth point raised in the background technology, the threaded rod of the spring preload adjustment component, such as the nut, is set to be relatively long. With a longer length, the preload stroke is also long enough. However, the long rod may cause it to fall off when rotated to the far end. Therefore, a constraint sleeve is set to constrain and fix the nut.

[0031] VI. Regarding the sixth point raised in the background art, a circular seat is provided inside the spring cavity to constrain the spring, and the circular surface of the circular seat can prevent the spring from being worn by sharp corners.

[0032] Note: The above designs are not in any particular order, and each one makes the present invention different from the prior art and a significant advancement. Attached Figure Description
