Referring to FIG. 1, FIG. 2 and FIG. 3, an intelligent heat-preserving pot cover comprises a cover body 1, wherein the cover body 1 is a glass cover, and a top portion of the cover body 1 is connected with a temperature control body 2. A ventilation hood 3 is arranged between the cover body 1 and the temperature control body 2. The ventilation hood 3 mainly discharges heat generated when the temperature control body 2 is working. A through hole 11 is arranged at the top portion of the cover body 1. The temperature control body 2 is provided with a heating tube 4 and an ultraviolet lamp tube 5 via a mounting column 21 passing through the through hole 11. The heating tube 4 may be arranged in an outer circle, and the ultraviolet lamp tube 5 may be arranged in an inner circle. A water tank 6 is arranged in the temperature control body 2, and a spray pipe 61 is led out of the water tank 6 and passes through the through hole 11. The spray pipe 61 is used to spray a small amount of water to ensure the taste of food and avoid the loss of water in the food after long-term heating and heat-preserving.

Referring to FIG. 3, the temperature control body 2 may be mounted in various ways. In this embodiment, the temperature control body 2 is connected with a clamping plate 23 via a pull rod 22 passing through the through hole 11. The clamping plate 23 presses against a bottom portion of the cover body 1. Of course, the temperature control body 2 may be directly mounted on the cover body 1 by a bolt.

In addition, an air-permeable plate 7 is provided below the heating tube 4 and the ultraviolet lamp tube 5, and the air-permeable plate 7 is mounted on the pull rod 22. The use of the air-permeable plate 7 effectively prevents food from directly contacting the heating tube 4 or the ultraviolet lamp tube 5.

The temperature control body 2 is provided with a temperature sensor 210, a humidity sensor 211 and a controller 213, and the controller 213 is configured for controlling the heating tube 4, the ultraviolet lamp tube 5 and the spray pipe 61 to work according to data of the temperature sensor 210 and the humidity sensor 211.

The temperature control body 2 is provided with an exhaust fan 8 via a rotating shaft passing through the through hole 11. The exhaust fan 8 is provided with double-layer fan blades, an upper-layer fan blade 81 is arranged in a middle space of the ventilation hood 3, and a lower-layer fan blade 82 is arranged below the clamping plate 23 and above the heating tube 4 and the ultraviolet lamp tube 5. The upper-layer fan blade 81 can discharge the heat generated during the operation of the temperature control body 2 from the ventilation hood 3, and the lower-layer fan blade 82 blows the heat generated by the heating tube 4 into the pot, thereby raising the temperature in the pot.

The temperature control body 2 is provided with a handle 24, and the handle 24 is capable of being accommodated in a groove of the temperature control body 2, thus being convenient to carry and accommodate.

The product has two operation modes, and the first mode is manual operation, wherein a heat-preserving indicator lamp 25 and a disinfection indicator lamp 26 are arranged on the temperature control body 2. A heat-preserving control knob 27, a disinfection control knob 28 and a water adding button 29 are arranged on the temperature control body 2. A user may set a heat-preserving time and a heat-preserving temperature by rotating the heat-preserving control knob 27 according to actual needs, set a disinfection time by rotating the disinfection control knob 28, and realize a water adding function by pressing the water adding button 29.

The other mode is automatic mode, wherein the temperature control body 2 is further provided with an Internet of Things communication module 214 for communicating with a server 11, a mobile terminal 10 or a smart home control module 12, and the controller 213 is configured for controlling the heating tube 4, the ultraviolet lamp tube 5 and the spray pipe 61 to work according to an Internet of Things control signal sent by the Internet of Things communication module 214.

Parameter settings of different foods, such as meat, stir-fried dishes, seafood, etc., are set in the Internet of Things communication module 214. As long as the corresponding signals are sent to the Internet of Things communication module 214 through a mobile phone, the controller 213 can automatically control the heating tube 4, the ultraviolet lamp 5 and the spray pipe 61 to work, such as in a meat heat-preserving mode, which may comprises the steps as follows:

• • 1) detecting, by the temperature sensor 210, a temperature in the pot, and when the temperature in the pot is lower than 50° C., controlling, by the controller 213, the heating tube 4 to start operation, and when the temperature in the pot is higher than 75° C., controlling, by the controller 213, the heating tube 4 to stop operation;
  • 2) detecting, by the humidity sensor 211, a humidity in the pot, when the humidity in the pot is lower than 80%, controlling, by the controller 213, the spray pipe 61 to start spraying, and when the humidity in the pot is higher than 90%, controlling, by the controller 213, the spray pipe 61 to stop spraying; and
  • 3) when the spray pipe 61 starts spraying, controlling, by the controller 213, the ultraviolet lamp tube 5 to turn on, and after the spraying is finished, controlling, by the controller 213, the ultraviolet lamp tube 5 to automatically turn off after maintaining 180 seconds.

The product can control the heating tube 4, the ultraviolet lamp tube 5 and the spray pipe 61 in an automatic mode or a manual mode, so as to realize three functions of food heat-preserving, ultraviolet disinfection, humidification and freshness preservation, thus ensuring the freshness, quality and taste of the food, and thus being widely used in families.

The preferred embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skills in the art can make many modifications and changes according to the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by those of ordinary skilled in the art through logical analysis, reasoning or limited experiments on the basis of the existing technology according to the concept of the present invention shall fall within the protection scope determined by the claims.
