[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0024] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a food sterilizing device, comprising a shell 1 and a cover plate 2 arranged at the upper end thereof, a pneumatic shell 8 connected by a pneumatic tube 6 is arranged on the side of the shell 1, a pneumatic component 9 is arranged in the pneumatic shell 8, and the pneumatic component 9 includes a pneumatic plate 903 slidably connected to the inner side of the pneumatic shell 8, a through hole is arranged on the pneumatic plate 903, a connecting rod 905 is arranged through the top of the pneumatic shell 8, and a blocking member 904 in contact with the pneumatic plate 903 is arranged on the connecting rod 905, which is used for automatic pressure regulation inside the pneumatic shell 8;

[0025] A locking component 5 is provided on the outer surface of the shell 1, and the locking component 5 includes a rotating bracket 501, on which a threaded rod 502 is rotatably provided, and a threaded member 503 is threadedly provided on the threaded rod 502. The bottom of the threaded member 503 is in contact and squeezed with the cover plate 2 through a pressing member 504 to ensure the sealing effect inside the shell 1.

[0026] The pneumatic plate 903 is provided with a plurality of groups of elastic telescopic rods 902 with equal spacing, and a connecting bracket 901 is provided on the other end of the elastic telescopic rod 902, and the connecting bracket 901 is connected to the inner side surface of the pneumatic shell 8, and a sliding blocking member 907 is provided on the top of the connecting rod 905, and the diameter of the sliding blocking member 907 is larger than the inner diameter of the sliding limit member 906, and the diameter of the blocking member 904 is larger than the diameter of the through hole of the pneumatic plate 903, and a tray 10 is provided in the pneumatic shell 8, and a plurality of groups of air outlet valves 11 are provided on the bottom side of the pneumatic shell 8, and the conducting direction of the air outlet valve 11 is toward the outside of the pneumatic shell 8.

[0027] A discharge component 12 is provided on the pneumatic shell 8, and the discharge component 12 includes a sliding bracket 1201, and the sliding bracket 1201 is U-shaped. A sliding blocking plate 1203 is slidably provided on the sliding bracket 1201. A discharge hole 1202 is provided on the pneumatic shell 8, and the width of the sliding blocking plate 1203 is greater than the width of the discharge hole 1202. A sealing member is provided on the pneumatic plate 903, and the sealing member is in contact and extruded with the inner wall of the pneumatic shell 8. A plurality of groups of limiting grooves are provided on the tray 10.

[0028] The inner side surface of the sliding bracket 1201 is provided with a sliding groove, and the side surface of the sliding blocking plate 1203 is provided with a sliding protrusion, and the sliding protrusion is slidably connected with the sliding groove.

[0029] This device can effectively improve the process of food sterilization to ensure that the food itself does not change. Compared with traditional devices, this device can reduce the loss of food nutrients caused by the sterilization process.

[0030] When the device is in working state, the heating element structure inside the shell 1 can effectively achieve the heating and evaporation effect of the water, thereby ensuring that a continuous supply of high-temperature steam is generated inside the device. The detachable cover 2 structure can facilitate the addition of water to the inside of the shell 1 from the outside, reducing the difficulty of use. When the cover 2 is closed, the threaded rod 502 is rotated to drive the threaded member 503 to the top of the pressing member 504 on the cover 2, so that the threaded member 503 can press the pressing member 504 downward during the rotation of the threaded member 503, thereby ensuring the locking and pressing effect of the cover 2 and avoiding steam leakage from the gap between the shell 1 and the cover 2.

[0031] When steam is generated inside the shell 1, the steam is transmitted through the air pressure pipe 6 and thus transmitted to the upper layer inside the air pressure shell 8. At this time, the air pressure inside the upper layer of the air pressure shell 8 gradually increases during the entry of steam, causing the air pressure plate 903 to slide downward. During the downward sliding of the air pressure plate 903, the structure of multiple sets of elastic telescopic rods 902 can prevent the air pressure plate 903 from tilting during the downward sliding of the air pressure plate 903, thereby ensuring the air pressure sealing of the device. At the same time, the elastic contraction tension of the elastic telescopic rod 902 can produce an upward pulling force on the air pressure plate 903, thereby reducing the descending speed of the air pressure plate 903, thereby making the air pressure pressure of the upper part higher.

[0032] When the air pressure plate 903 is in the process of descending, the blocking member 904 is covered over the through hole of the air pressure plate 903 by gravity, thereby ensuring the sealing of the air pressure plate 903. When the air pressure plate 903 continues to descend, the connecting rod 905 slides to the bottom, so that the sliding blocking member 907 contacts the top of the sliding limit member 906. At this time, the blocking member 904 can no longer continue to descend, so that a gap is generated between the air pressure plate 903 and the blocking member 904.

[0033] When a gap is formed between the blocking member 904 and the air pressure plate 903, the high-pressure steam can be transmitted to the lower part of the air pressure shell 8 through the structure of the gap and the through hole. At this time, the high-pressure steam can only flow out through the outlet valve 11 in the lower part of the air pressure shell 8, thereby realizing the one-way flow effect of steam in the device and ensuring the cleanliness of the inside of the air pressure shell 8.

[0034] When a part of the steam leaks out through the gap between the blocking member 904 and the air pressure plate 903, the air pressure inside the upper part of the air pressure shell 8 drops, and the air pressure plate 903 slides upward under the drive of the elastic telescopic rod 902. When the air pressure plate 903 slides upward to a certain extent, the air pressure plate 903 and the blocking member 904 are in contact and sealed again, so that the steam cannot leak downward, and the air pressure plate 903 is in a state of storing steam again.

[0035] By reciprocatingly switching the above-mentioned working states, the intermittent steam eruption effect of the device can be achieved, so that when food is placed on the tray 10 through the discharge hole 1202, it can be intermittently circulated and flushed by high-temperature steam within a certain period of time. The intermittent steam can increase the temperature of the food when erupting, and reduce the temperature of the food when not erupting, thereby avoiding problems such as protein denaturation of food due to continuous high temperature. The structure of the sliding blocking plate 1203 can ensure the stable sealing effect of the pneumatic shell 8.

[0036] Embodiment 2: Figure 1-4As shown, a food sterilization device disclosed in Example 2 of the utility model has a structure that is basically the same as that in Example 1, except that a drain valve 7 is provided on the shell 1, a pressure gauge 3 is provided on the cover plate 2, a pressure relief valve 4 is provided on the cover plate 2, a heating element is provided inside the shell 1, the pressing element 504 is U-shaped, and the diameter of the threaded element 503 is larger than the internal width of the pressing element 504.

[0037] The pressure gauge 3 structure of the device can monitor the current air pressure inside the shell 1 in real time, so as to ensure that the device is within a safe pressure range. When the pressure inside the shell 1 exceeds the safe range, the pressure inside the shell 1 can be quickly relieved through the pressure relief valve 4, thereby avoiding the risk of explosion.
