[0029] In order for those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] Embodiment one

[0031] The specific technical problem solved by the present embodiment is that the existing food temperature probe needs to transmit the temperature signal obtained by the sensor to the external device through the antenna when detecting the internal temperature of food. The existing temperature probe structure is that a cavity structure is arranged in the handle, and the antenna for wireless transmission is arranged in the cavity structure in the form of a suspended metal wire. One end of the antenna is connected with the circuit board of the probe main body, the circuit board is connected with the temperature sensor, and the other end of the antenna is suspended in the cavity structure in the handle. The temperature sensor is arranged at the tip of the probe main body to detect the temperature signal at the deepest part of the food and transmit the temperature signal out through the antenna suspended in the handle. This structure has application defects, such as easy signal interference between the handle or other metal wires, and the size and shape of the antenna are limited by the cavity space in the handle and cannot be made larger. In terms of product quality, the antenna structure suspended in the cavity of the handle inevitably has a large positional deviation during installation, and finally causes inconsistent signal transmission capacity of the products in the same batch.

[0032] In order to solve the problems of handle limitation, wire interference and product quality consistency, the present embodiment proposes a brand-new handle structure, an integrated antenna handle, as shown in Figure 1 The integrated antenna handle includes a handle body 10, a metal antenna 20 and a protective layer 30. The metal antenna 20 is not arranged in the cavity inside the handle body 10, but is arranged on the outside of the handle body 10 and is limited and protected by the protective layer 30.

Preferably, the handle body 10 is a ceramic blank, and the protective layer 30 is a glaze layer, which is formed by thick film technology, or the handle body 10 is a ceramic blank, and the protective layer 30 is a ceramic layer, which is formed by co-firing technology.

[0034] In terms of structure, the metal antenna 20 is arranged on the outside of the handle body 10 and is naturally physically isolated from the power line, sensor wire and the like, greatly reducing the signal interference received by the metal antenna 20 and also preventing signal shielding by the handle body 10 itself.

[0035] In terms of size, the metal antenna 20 is no longer subject to the volume limitation of the internal cavity 11 inside the handle body 10;

[0039] Specifically, the cross-sectional shape of the handle body 10 includes a circle, a square, an ellipse, a rectangle, and a triangle. The printed metal antenna 20 is printed on the peripheral surface of the handle body 10 in a three-dimensional structure, which is a breakthrough and innovation in the temperature probe field. The handle body 10 is usually a circular handle, but other square, triangular, and other shaped handles are obviously within the protection scope of the present application.

[0040] Specifically, the overall shape of the metal antenna 20 can be a traditional straight line type, a broken line type, or an F type, and is preferably a spiral spring shape as shown in Figure 2 which can rotate around the handle body 10, or a more complex structure of a mesh type.

[0041] Specifically, the cross-sectional shape of the metal antenna 20 after sintering and forming can be a circle, a semicircle, a semi-ellipse, a trapezoid, or a rectangle, and is preferably a semicircle or a rectangle.

[0042] Specifically, the size of the metal antenna 20 is selected according to requirements, and the height is usually greater than 0.001 mm and can reach the thickness of the protective layer 30. In some special cases, the metal antenna 20 can exceed the protective layer 30.

[0043] Specifically, as shown in Figure 3 the handle body 10 is provided with an antenna pad 21 at the connection part with the probe body, the antenna pad 21 is connected with the metal antenna 20, and when the handle body 10 is connected with the probe body, the metal antenna 20 is connected with the PCB in the probe body through the antenna pad 21.
