The heat is evenly melted, and the cut surface of the food is effectively moved along the blade body 1 to have a flat shape. At the same time, the heat of the blade body 1 can be more effective when applied. Since the butter itself is solid in a refrigerated state, it cannot be effectively dispersed evenly, and the heat of the blade body 1 can quickly melt the butter on both sides of the blade body 1 so that it can be used. When the blade 1 is applied, it can be melted into a liquid state while being moved, and evenly applied. Since the heating tool can generate heat, when not in use, the food on the tool can be directly washed with water by the heat, and the uniform heating property is more favorable for cleaning.

A sealed space is formed in the groove 22 between the two half-frame outer casings 21. Since the electronic components are disposed inside the shank 2, it is necessary to ensure the waterproof requirement, and the interference fit of the sealing strip can ensure the requirement of dense water and dense air to achieve internal waterproofing of the shank 2.

As a further description of the above-described heating type food cutting tool, the heating body 12 is a PCB board that conforms to the cross-sectional shape of the blade body casing 11. The PCB board is provided with a heat conducting sheet and an LED lamp 13, and the heat conducting sheet is evenly distributed on the PCB board at both sides of the blade body casing 11, and the PCB board passes through the heating resistor and The lithium battery placed in the shank 2 is electrically connected, and the lithium battery supplies electric energy to the heating resistor to generate heat, and the heat is generated by the heating resistor to conduct heat to the heat conducting sheet to uniformly conduct heat, or to supply electric energy to the LED lamp 13 for illuminating. The LED lamp 13 has two functions: uniform distribution for illuminating, and when the food is cut thin or has high transparency, the light can be emitted through the food body, thereby obtaining the cutting depth and cutting of the cutter through the side of the cutting surface. Thickness, this LED lamp 13 mainly works in the case of insufficient light, which can effectively help people to produce visual aid in the cutting process; the other function is mainly auxiliary heating of cutting, because the LED lamp 13 can generate heat, it is evenly arranged The heat generated by the LED lamp 13 can be effectively utilized to improve the energy utilization rate of the tool. At the same time, the PCB board is provided with a temperature collecting module and a temperature control module, and the real-time temperature of the heat conducting sheet of the PCB board is collected by the temperature collecting module, and the temperature control module can control the temperature of the heat conducting sheet to be too high or too low, and disconnected The power supply or the current is increased to adjust the temperature to a preset temperature.

As a further description of the above-mentioned heat-generating food tool, the bottom of the handle 2 is provided with a charging hole 24, and the charging plug is inserted into the charging hole 24 to be electrically connected to the lithium battery 25; the charging hole 24 A waterproof plug 26 is fixed to one side, and the waterproof plug 26 has an interference fit with the charging hole 24 to form a sealed space with the bottom of the shank 2. The built-in rechargeable battery of the tool is connected to the external charging cable for charging when the charging hole is needed at the bottom. When used normally, the waterproof plug is used to effectively keep the sealed state, which is dustproof and waterproof, and protects the internal charging structure.

As a further description of the above-described heat-generating food cutting tool, the side edges of the blade body casing 11 are elliptical, and as the blade body 1, both sides thereof can be used as a smear at the same time.

As a further description of the above-mentioned heating type food cutter, the outer portion of the blade body casing 11 is covered with a spoon sleeve 3, the top of the spoon sleeve 3 is a spoon portion, and the bottom portion is outside the blade body. The shells 11 are parallel and flat. By setting a spoon cover in the blade body casing 11, the tool can be used as a spoon in addition to smear cutting, and is mainly used for ice-cold food such as ice cream, because the ice-cold food is directly used in excavation, and some people are harder. It is not convenient to eat, but needs to use more force to dig, or to naturally melt it. The former is prone to the problem of damage caused by tools such as edible sticks, but the latter needs to wait for time, not for the user. Convenience.

The method for using the heat-generating food tool provided by the present invention comprises the steps of: turning on the tool circuit to make the heat conductive sheet or the LED lamp 13 uniformly disposed on the tool work, and after the heat is evenly transmitted to both sides of the blade body casing 11, Use a knife to smear or cut food.
