Description

Technical Field

[0001] This utility model relates to the field of food storage container technology, and in particular to a food preservation box. Background Technology

[0002] Food storage containers, as commonly used containers for daily food storage, primarily aim to extend the shelf life of food and prevent spoilage due to environmental factors. However, during use, especially in refrigerated environments, the warm, humid air inside the container easily condenses into water on the inside of the lid. If this condensation drips directly onto or remains on the food surface, it can cause the food to become damp, moldy, and even accelerate spoilage, severely impacting its preservation effect.

[0003] Meanwhile, traditional food storage containers rely on a single sealing structure to preserve freshness, lacking functions such as active sterilization and reducing oxygen contact, thus limiting the preservation time of easily perishable ingredients such as meat and leafy green vegetables.

[0004] To address the aforementioned issues, this invention proposes a food preservation box that significantly improves food preservation and ease of use by optimizing the condensate drainage structure and combining sterilization and vacuum preservation functions. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model proposes a food preservation box.

[0006] This utility model proposes a food preservation box, which includes a box body and a lid;

[0007] The inner bottom of the cover is provided with a boss, which has a first direction extending along its own length and a second direction extending along its own width.

[0008] The bottom side of the boss forms an inclined first surface along a first direction, and the first inclined surface gradually decreases from one end of the boss to the other end.

[0009] Multiple sets of parallel strip grooves extending along the first direction are formed on the first inclined surface. The bottom surface of each strip groove is parallel to the first inclined surface. After the condensate condenses on the bottom surface of the groove, it can be guided to the side wall of the strip groove.

[0010] Each of the strip grooves has a second inclined surface formed on the bottom surface along the second direction. The second inclined surface gradually decreases from one side of the strip groove to the other side. A water guide strip extending along the first direction is provided on the lowest side of the bottom surface of the strip groove. The water guide strip protrudes from the bottom surface of the groove and its surface is parallel to the bottom surface of the groove. Condensate on the side wall of the strip groove can be collected in the water guide strip.

[0011] The box is equipped with a vertical partition, which, together with the inner wall of the box, forms a collection cavity for collecting condensate. The collection cavity is located directly below the lowest end of the boss along the downward direction of the first inclined surface. The condensate on the water guide strip can be uniformly guided into the collection cavity.

[0012] The box body has a drain outlet at the bottom of the side wall corresponding to the collection chamber, and the drain outlet is equipped with a sealing structure for sealing.

[0013] Preferably, the area on the protrusion without the groove is provided with multiple sets of ultraviolet lamps for sterilization. The protrusion has an integrated battery inside, which is electrically connected to each ultraviolet lamp. The outer surface of the cover is provided with a charging interface that is electrically connected to the battery. The charging interface is used to connect an external data cable to power the battery.

[0014] Preferably, the ultraviolet lamp is a UV-C type germicidal lamp bead, and the outer surface of the cover is also provided with a control switch, which is connected in series between the battery and the ultraviolet lamp to control the turning on and off of the ultraviolet lamp.

[0015] Preferably, the cover is provided with an air extraction port, which is used to connect to an external air pump to extract air from the closed cavity formed after the box and the cover are fastened together; the cover is also provided with an air vent, and a sealing plug for sealing the air vent is detachably connected inside the air vent.

[0016] Preferably, the multiple sets of the strip grooves are evenly spaced along the second direction of the boss.

[0017] Preferably, the first inclined surface has an inclination angle of 3°-10° relative to the horizontal section of the boss, and the second inclined surface has an inclination angle of 5°-15° relative to the horizontal section of the bottom of the groove.

[0018] Preferably, the sealing structure of the drain outlet is a silicone sealing plug or a threaded sealing cap, wherein the silicone sealing plug is interference-fitted with the drain outlet, and the threaded sealing cap is threadedly connected to the drain outlet.

[0019] The food preservation box proposed in this invention achieves efficient and directional collection of condensate through a combination structure of a first inclined surface, a strip groove, a second inclined surface, a water guide strip, and a collection cavity. This avoids condensate from contacting food, significantly reduces the probability of food becoming damp and spoiling, and improves the preservation effect.

[0020] It integrates UV-C ultraviolet sterilization function, which can actively kill microorganisms on the surface of food, further extending the shelf life of food, and the battery-powered design improves the flexibility of use scenarios.

[0021] Equipped with a vacuum preservation structure, it reduces the oxygen concentration inside the box, inhibiting food oxidation and spoilage, and is suitable for storing a variety of perishable ingredients.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] like Figures 1-5 The food storage container shown has the following structure:

[0032] Boss 201: A boss 201 is provided on the inner bottom of the cover 2. The boss 201 has a first direction extending along its own length and a second direction extending along its own width. The boss 201 is configured to provide a carrier for the condensation and flow of condensate, and to prevent condensate from dripping directly onto the food surface at the bottom of the box 1.

[0033] First inclined surface and strip groove 203: The bottom side of the boss 201 forms an inclined surface along the first direction, and the first inclined surface gradually decreases from one end of the boss 201 to the other end; multiple sets of strip grooves 203 extending along the first direction and parallel to each other are opened on the first inclined surface, and the bottom surface of each strip groove 203 is parallel to the first inclined surface.

[0034] The condensate first condenses on the bottom surface of the strip groove 203. Since the bottom surface of the groove is parallel to the first inclined surface and the first inclined surface is inclined, the condensate will be guided along the bottom surface of the groove to the side wall of the strip groove 203 under the action of gravity, thus completing the initial flow guidance.

[0035] Second inclined surface and water guide strip 204: The bottom surface of each strip groove 203 forms an inclined surface along the second direction. The second inclined surface gradually decreases from one side of the strip groove 203 to the other side. A water guide strip 204 extending along the first direction is provided on the lowest side of the bottom surface of the strip groove 203. The water guide strip 204 protrudes from the bottom surface of the groove and its surface is parallel to the bottom surface of the groove.

[0036] The condensate on the side wall of the guide strip groove 203 will be further collected on the water guide strip 204 located at the lowest side of the bottom surface of the groove due to the inclination characteristics of the second inclined surface. The water guide strip 204 extends along the first direction and is consistent with the inclination direction of the first inclined surface, so that the condensate can be guided along the water guide strip 204 to the lowest end of the boss 201.

[0037] Collection chamber and drain outlet 102: The box body 1 is provided with a vertical partition 101. The vertical partition 101 and the inner side wall of the box body 1 form a collection chamber for collecting condensate. The collection chamber is located directly below the lowest end of the boss 201 along the first inclined surface downward direction. The condensate on the water guide strip 204 can be uniformly guided into the collection chamber. The bottom of the side wall of the box body 1 corresponding to the collection chamber is provided with a drain outlet 102. The drain outlet 102 is equipped with a sealing structure for sealing.

[0038] The collection chamber centrally stores the condensate introduced by the water guide strip 204, preventing the condensate from coming into contact with food. When it is necessary to clean the condensate, the sealing structure of the drain outlet 102 can be opened to drain the condensate without disassembling the box 1 or taking out the food, making it convenient to use.

[0039] bactericidal structure

[0040] The area on the protrusion 201 without the groove 203 is equipped with multiple sets of ultraviolet lamps 202 for sterilization. The protrusion 201 integrates a battery, which is electrically connected to each ultraviolet lamp 202. The outer surface of the cover 2 is equipped with a charging interface that is electrically connected to the battery. The charging interface is used to connect an external data cable to power the battery. Furthermore, the ultraviolet lamp 202 is a UV-C type sterilization lamp bead. The outer surface of the cover 2 is also equipped with a control switch, which is connected in series between the battery and the ultraviolet lamp 202 to control the opening and closing of the ultraviolet lamp 202.

[0041] The UV-C type germicidal lamp bead emits ultraviolet light with a wavelength of 200-280nm, which can effectively kill bacteria, mold and other microorganisms on the surface of food inside the box, reducing food spoilage caused by microbial growth; the battery provides independent power for the UV lamp 202, without relying on an external power source, and is suitable for various scenarios such as inside the refrigerator and outdoors; the control switch can flexibly control the sterilization time according to usage needs, avoiding energy waste.

[0042] Vacuum preservation structure

[0043] The cover 2 is provided with an air extraction port 301, which is used to connect to an external air pump to extract the air from the closed cavity formed after the box 1 and the cover 2 are fastened together; the cover 2 is also provided with an air vent 302, and a sealing plug for sealing the air vent 302 is detachably connected inside the air vent 302.

[0044] By using the air extraction port 301 in conjunction with an external air pump, air can be extracted from the box to reduce the oxygen concentration inside, thereby reducing browning and spoilage of food caused by oxidation, such as fruit oxidation and meat spoilage. The vent 302 makes it easy to open the lid 2 under vacuum conditions. Simply remove the sealing plug to allow air to enter the box, and the lid 2 can be opened easily, improving the user experience.

[0045] Multiple sets of strip grooves 203 are evenly spaced along the second direction of the boss 201;

[0046] The first inclined surface has an inclination angle of 3°-10° relative to the horizontal section of the boss 201, and the second inclined surface has an inclination angle of 5°-15° relative to the horizontal section of the bottom of the tank. The design of the inclination angle takes into account both the condensate flow efficiency and the overall structural stability of the boss 201. It ensures that the condensate can flow smoothly under the action of gravity, while avoiding excessive space occupation or structural deformation of the boss 201 due to excessive inclination angle.

[0047] The sealing structure of the drain outlet 102 is a silicone sealing plug or a threaded sealing cap. The silicone sealing plug is interference-fitted with the drain outlet 102, and the threaded sealing cap is threadedly connected to the drain outlet 102. Both sealing structures can achieve a good sealing effect, prevent condensate leakage in the collection chamber, and facilitate user disassembly and cleaning.

[0048] In this embodiment, during operation:

[0049] Condensation collection process: After the cover 2 is fastened to the box 1, the hot and humid air inside the box condenses into condensate on the surface of the protrusion 201 on the inner side of the cover 2, especially on the bottom surface of the groove 203. The condensate is guided along the bottom surface of the groove parallel to the first inclined surface to the side wall of the groove 203, and then collected by the second inclined surface to the water guide strip 204. The water guide strip 204 guides the condensate to the lowest end of the protrusion 201 in the first direction, and finally flows into the collection chamber below. When cleaning is required, the condensate can be discharged by opening the sealing structure of the drain outlet 102.

[0050] Sterilization process: When it is necessary to sterilize the food inside the box, turn on the ultraviolet lamp 202 through the control switch on the surface of the lid 2. The UV-C type lamp bead emits ultraviolet light to sterilize the food surface; when the battery power is low, charge the battery by connecting an external data cable through the charging interface.

[0051] Vacuum preservation process: After placing the food into the container 1, close and seal the lid 2; connect the external air pump to the air extraction port 301 of the lid 2, start the air pump to extract the air from the container and create a vacuum environment; when it is necessary to open the lid 2, remove the sealing plug of the vent 302 to allow air to enter the container, and it can be easily opened.
