Description

Technical Field

[0001] This utility model relates to the technical field of catering utensils, and in particular to a hygienic insulated tableware. Background Technology

[0002] Most tableware on the market is currently made of ceramic. Ceramic bowls are easy to clean and heat-resistant. However, tableware that can keep food warm often uses stainless steel as the inner liner. Stainless steel may leach heavy metals and does not have antibacterial or bacteriostatic effects. Therefore, if there is food residue on the tableware, bacteria can easily grow, contaminating the food and making the tableware unhygienic. In particular, many existing baby food bowls use stainless steel as the inner liner for heating and heat preservation. However, if heavy metals or oxides are produced after long-term use, they will contaminate the food. If the baby eats the baby food from the bowl, it will affect the baby's health and growth. If the baby food is left in the inner liner for a long time, bacteria will grow in the inner liner, and the food will easily spoil. If the baby eats it, it will cause digestive discomfort symptoms such as diarrhea and abdominal pain. Utility Model Content

[0032] The following is combined Figures 1 to 6 This invention describes a hygienic insulated tableware according to an embodiment of the present invention, comprising a shell 1, an inner liner 2, a heating film 3, and a power supply 4;

[0033] The surface of the inner liner 2 is covered with an enamel layer, which includes an antibacterial layer;

[0034] The inner liner 2 is disposed inside the shell 1, and the power supply 4 is disposed below the inner liner 2;

[0035] The outer wall of the inner liner 2 is provided with a heating film 3, which is connected to the power supply 4 and is used to heat the inner liner 2.

[0036] Currently, most tableware on the market is made of ceramic, while tableware that can keep food warm often uses stainless steel as the inner liner 2. Stainless steel does not have antibacterial or bacteriostatic effects, so bacteria can grow in the inner liner 2 after prolonged use, leading to unhygienic tableware. This is especially true for baby food bowls, where prolonged placement of baby food in the inner liner 2 can cause bacterial growth, making the food prone to spoilage and potentially causing diarrhea in infants. Specifically, in this embodiment, the surface of the inner liner 2 is manufactured using an enamel process. The enamel process incorporates antibacterial and bacteriostatic materials, giving the enamel layer of the inner liner 2 an antibacterial and bacteriostatic effect. Furthermore, the presence of the enamel layer prevents the leaching of heavy metals and oxides. Simultaneously, a heating film 3 is installed on the outer wall of the inner liner 2. Powered by a power source 4, the heating film 3 heats and keeps the inner liner 2 warm. This invention not only achieves heating and heat preservation but also provides the inner liner 2 with antibacterial and bacteriostatic properties, preventing bacterial contamination and food spoilage, ensuring cleanliness, hygiene, and the health of the consumer.

[0037] Furthermore, a number of locking elements 5 are fixedly provided at the bottom of the inner liner 2, and a number of bolt mounting seats 6 corresponding to the number of locking elements 5 are provided at the bottom of the shell 1. The bolt mounting seats 6 are threadedly connected to the locking elements 5 by bolts, so that when the bolts are tightened, the inner liner 2 moves closer to the bottom of the shell 1.

[0038] Specifically, in this embodiment, when installing the inner liner 2, the locking member 5 is aligned with the corresponding bolt mounting seat 6. A bolt is placed on the bolt mounting seat 6, the bolt is inserted into the locking member 5, and the bolt is tightened to pull the locking member 5 towards the bolt mounting seat 6, thereby fixing the inner liner 2 to the shell 1. This ensures a tight connection between the inner liner 2 and the shell 1 without gaps, guaranteeing a seal and preventing water or food from entering the shell 1, thus ensuring the cleanliness and hygiene of the interior of the shell 1. When disassembling, the inner liner 2 can be removed by simply removing the bolt, making the operation simple and convenient.

[0039] Furthermore, the bottom of the locking member 5 is provided with a threaded post 51, the inner wall of the threaded post 51 is provided with internal threads, and the bolt mounting seat 6 is provided with a mounting hole 61. When the bolt is installed, the bolt passes through the mounting hole 61 and is threadedly connected to the internal thread of the threaded post 51.

[0040] Specifically, in this embodiment, when tightening the bolt, the locking member 5 is actually pulled towards the bolt mounting seat 6. Therefore, the threaded post 51 is set to ensure the stability of the bolt when the locking member 5 is tightened, avoid deformation of the locking member 5, and ensure that the installation structure of the inner liner 2 is reliable, while ensuring a tight seal between the inner liner 2 and the shell 1.

[0041] Furthermore, the locking element 5 and the bolt mounting seat 6 are respectively provided in three sets. The three sets of locking elements 5 are arranged in a circle around the center of the inner liner 2, and the three sets of bolt mounting seats 6 are arranged in a circle around the center of the shell 1.

[0042] Specifically, in this embodiment, the three sets of locking components 5 and bolt mounting seats 6 are arranged equidistantly around the circumference, with each set having an angle of 120 degrees. This ensures that the inner liner 2 is subjected to uniform force when locking the inner liner 2, further improving the stability and reliability of the structural connection.

[0043] Furthermore, the bottom of the housing 1 is provided with an anti-slip rubber ring 7, which is located directly below the bolt mounting seat 6 and is used to shield the bolt mounting seat 6.

[0044] Specifically, in this embodiment, the anti-slip rubber ring 7 not only serves to prevent slipping, but is also positioned directly below the bolt mounting base 6. After the bolt is installed, the anti-slip rubber ring 7 covers the bolt hole, which not only provides waterproofing but also prevents the hole from being exposed, resulting in a more aesthetically pleasing overall appearance.

[0045] Furthermore, the outer edge of the inner liner 2 is provided with a downwardly bent pressing part 21, the top edge of the shell 1 is provided with a sealing groove 11, the bottom of the sealing groove 11 is provided with a sealing ring 12, and the pressing part 21 is limited and disposed within the sealing groove 11.

[0046] Specifically, in this embodiment, when the inner liner 2 is installed, the pressing part 21 of the inner liner 2 is inserted into the sealing groove 11. By pressing the sealing ring 12 at the bottom of the sealing groove 11, the tightness and sealing of the inner liner 2 and the shell 1 are ensured, avoiding gaps between the inner liner 2 and the shell 1 that could lead to water ingress, and further improving cleanliness, hygiene and structural sealing.

[0047] Furthermore, it also includes a temperature sensor and a display operation screen 8. The temperature sensor is used to detect the temperature of the inner liner 2. The temperature sensor is communicatively connected to the display operation screen 8, which is used for temperature display and user operation.

[0048] Specifically, in this embodiment, the temperature sensor can sense the temperature of the inner pot 2 and feed the signal back to the display screen 8. The display screen 8 can display the temperature, and the user can intuitively obtain the temperature of the inner pot 2, thereby ensuring that the food temperature is not too hot or too cold.

[0049] Furthermore, the heating film 3 includes a sidewall film 31 and a bottom film 32. The outer sidewall of the inner liner 2 is provided with a plurality of the sidewall films 31, and the bottom surface of the inner liner 2 is provided with a plurality of the bottom films 32. The sidewall films 31 and the bottom films 32 are respectively connected to the power supply 4.

[0050] Specifically, in this embodiment, the combined heating of the inner liner 2 by heating the sidewall of the inner liner 2 with the sidewall membrane 31 and heating the bottom surface of the inner liner 2 with the bottom membrane 32 can help improve the heat preservation performance of the inner liner 2, ensure the temperature of the food, and prevent the food from getting cold.

[0051] Furthermore, it also includes an upper cover 9, the inner sidewall of which is inclinedly provided with a plurality of first locking strips 91, the first locking strips 91 being arranged circumferentially on the inner sidewall of the upper cover 9, and the outer sidewall of the upper part of the housing 1 being correspondingly inclinedly provided with a second locking strip 13. When the upper cover 9 is closed on the housing 1 and the upper cover 9 is rotated, the first locking strips 91 and the second locking strips 13 can be fastened to each other.

[0052] Specifically, in this embodiment, the top cover 9 can seal the food to prevent bacteria, dust and other contaminants from entering the inner liner 2 and contaminating the food. The top cover 9 is locked by screwing it on after it is closed on the shell 1, so that the inclined first locking bar 91 and the second locking bar 13 can be locked together, thus preventing the top cover 9 from falling off.

[0053] Furthermore, a sealing ring 92 is provided on the inner wall of the upper cover 9.

[0054] Specifically, in this embodiment, a sealing ring 92 is fixedly provided inside the upper cover 9. After the upper cover 9 is locked, the outer edge of the shell 1 will press the sealing ring 92, thereby making the connection between the upper cover 9 and the shell 1 tight and sealed, preventing water, dust and other contaminants from entering the inner liner 2, and improving the hygiene performance of the tableware.
