DETAILED DESCRIPTION

[0040] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0041] Please refer to the following Figures 1 to 11 The heating device 100 and the supplementary food machine 200 according to the embodiment of the present utility model are described.

[0042] like Figure 1-Figure 3 As shown, the heating device 100 of the embodiment of the utility model includes a heating element 1, a thermal protection assembly 2 and a fixing member 3. The thermal protection assembly 2 includes a thermostat 21, a fuse 22 and a temperature sensor 23. The fixing member 3 is connected to the heating element 1, and the fixing member 3 is provided with a first matching portion 31, a second matching portion 32 and a third matching portion 33. The first matching portion 31 is used to fix the thermostat 21 and the thermostat 21 is fitted with the heating element 1, the second matching portion 32 is used to fix the fuse 22 and the fuse 22 is fitted with the heating element 1, and the third matching portion 33 is used to fix the temperature sensor 23 and the temperature sensor 23 is fitted with the heating element 1.

[0043] In the heating device of the embodiment of the utility model, the thermostat 21, the fuse 22 and the temperature sensor 23 are connected to the heating element 1 through the same fixing member 3, so that the thermostat 21 matched in the first matching portion 31, the fuse 22 matched in the second matching portion 32 and the temperature sensor 23 matched in the third matching portion 33 can not only fit tightly with the heating element 1 to improve the temperature sensing effect of the thermostat 21, the fuse 22 and the temperature sensor 23, but also make the thermostat 21, the fuse 22 and the temperature sensor 23 evenly stressed, so as to reduce the risk of damage or reduced accuracy caused by uneven stress when installing the thermal protection component 2, and ensure the service life of the thermostat 21, the fuse 22 and the temperature sensor 23.

[0044] Alternatively, if Figure 1-Figure 2 As shown, the heating element 1 includes a heating disc 11 and a heating tube 12. The heating tube 12 is arranged around the circumference of the heating disc 11, and the two ends of the heating tube 12 are arranged at intervals. The heating disc 11 includes a stainless steel plate (not shown) and an aluminum plate stacked on the stainless steel plate. The heating tube 12 is arranged on a side of the aluminum plate away from the stainless steel plate. Due to the good thermal conductivity of the aluminum plate, the heat of the heating tube 12 can be better transferred to the stainless steel plate.

[0045] Optionally, the heating device 100 further includes a first silicone member 41, a second silicone member 42 and a third silicone member 43. One end of the first silicone member 41 abuts against the first matching portion 31, and the other end of the first silicone member 41 abuts against the thermostat 21;

[0046] And / or, one end of the second silicone member 42 abuts against the second matching portion 32 , and the other end of the second silicone member 42 abuts against the fuse 22 ;

[0047] And / or, one end of the third silicone member 43 abuts against the third matching portion 33 , and the other end of the third silicone member 43 abuts against the temperature sensor 23 .

[0048] Specifically, one side of the thermostat 21 abuts against the first silicone member 41, the other side of the thermostat 21 fits against the heating element 1, one side of the fuse 22 abuts against the second silicone member 42, the other side of the fuse 22 fits against the heating element 1, one end of the third silicone member 43 abuts against the third matching portion 33, and the other end of the third silicone member 43 abuts against the temperature sensor 23. The silicone member has a shock-absorbing effect, so that the thermostat 21, the fuse 22 and the temperature sensor 23 can not only fit tightly and effectively on the heating element 1, but also will not be damaged due to the fixing member 3 being pressed too tightly, thereby ensuring product quality.

[0049] Optionally, at least one of the first matching portion 31 , the second matching portion 32 and the third matching portion 33 is a through hole 5 or a groove (not shown).

[0050] Specifically, Figure 3 As shown, the first matching portion 31 and the second matching portion 32 are both through holes 5, at least a portion of the first silicone member 41 is matched in the through hole 5 of the first matching portion 31, and at least a portion of the second silicone member 42 is matched in the through hole 5 of the second matching portion 32, so that the first silicone member 41 and the second silicone member 42 are firmly matched with the matching portions on the fixing member 3 and the matching method is simple.

[0051] It is understandable that the third matching portion 33 may also be a through hole 5, which is similar to the configuration of the first matching portion 31 and the second matching portion 32. However, the present invention is not limited thereto. Figure 3 As shown, the fixing member 3 has a protrusion 35 on the side facing the heating element 1, the protrusion 35 is located between the first matching portion 31 and the second matching portion 32, and the protrusion 35 forms a third matching portion 33 on the side facing the heating element 1. The protrusion 35 is provided with a through hole 351 for leading out the wiring of the temperature sensor 23.

[0052] Specifically, since the mounting hole 14 is located on the aluminum plate, the protrusion 35 is arranged at the position corresponding to the temperature sensor 23, which shortens the distance between the fixing member 3 and the aluminum plate, facilitates the abutment between the temperature sensor 23 and the fixing member 3, and the fixing member 3 is not easy to move relative to the heating element 1, thereby ensuring that the temperature sensor 23 is not easily affected by the shear force generated when the fixing member 3 and the heating element 1 move relative to each other, thereby ensuring the service life of the temperature sensor 23.

[0053] Optionally, at least one of the first silicone member 41 , the second silicone member 42 and the third silicone member 43 has a step at one end thereof abutting against the corresponding matching portion, and the step is matched in the through hole 5 or the groove.

The first step 411 is matched with the through hole 5 on the first matching portion 31, so that the matching mode of the first silicone member 41 and the first matching portion 31 is simple and effective, and the first silicone member 41 has a simple structure, is easy to manufacture, and saves costs.

[0055] The second silicone member 42 has a second step 421 at one end that abuts against the second matching portion 32. The cross-sectional area of ​​the second step 421 is smaller than the cross-sectional area of ​​the second silicone member 42. The central axis of the second step 421 is colinear with the central axis of the second silicone member 42. The second step 421 is matched with the through hole 5 on the second matching portion 32, so that the matching mode of the second silicone member 42 and the second matching portion 32 is simple and effective, and the second silicone member 42 has a simple structure, is easy to manufacture, and saves costs.

[0056] Specifically, the first step 411 and the second step 421 are both provided with a receiving portion 44, and there are two receiving portions 44, which are arranged at intervals. When the first silicone member 41 and the second silicone member 42 are matched with the matching portion of the fixing member 3, at least part of the side surface of the step can be received in the receiving portion 44, so that the matching portion squeezes the receiving portion 44, so that the step and the matching portion achieve interference fit, thereby improving the matching efficiency of the step and the fixing member 3.

[0057] Specifically, the through hole 5 includes a first hole segment 51 and a second hole segment 52 that are connected to each other, and a cross-sectional area of ​​the first hole segment 51 is greater than a cross-sectional area of ​​the second hole segment 52 .

[0058] Specifically, Figure 1 , Figure 3-Figure 11 As shown, a part of the silicone piece fits in the first hole section 51, and at least a part of the step fits in the second hole section 52, thereby improving the fit between the silicone piece and the fixing piece 3 and improving the stability of the silicone piece installed in the fitting portion. In addition, the heating device of the embodiment of the utility model fits the silicone piece in the first hole section 51 by fitting the step in the second hole section 52, and the cross-sectional area of ​​the first hole section 51 is larger than the cross-sectional area of ​​the second hole section 52, so that when the fixing piece 3 squeezes the silicone piece, the silicone piece is not easily squeezed out of the second hole section 52, thereby improving the fit between the silicone piece and the fixing piece 3 and the tightness of the connection.

[0059] Optionally, the end surface of one end of the first silicone member 41 that abuts against the thermostat 21 is a plane (not shown) or is provided with a first recess 45, and the thermostat 21 is at least partially fitted in the first recess 45;

[0062] Specifically, a first recess 45 is provided on the end surface of the first silicone member 41 facing the thermostat 21. The first recess 45 extends along the extension direction of the heating tube 12. The thermostat 21 is fitted in the first recess 45, which not only increases the contact area between the thermostat 21 and the first silicone member 41, so that the thermostat 21 is firmly installed in the first recess 45, but also limits the thermostat 21, so that the thermostat 21 and the heating element 1 fit better and more firmly.

[0063] Specifically, the end surface of the second silicone member 42 facing the fuse 22 is a plane 46, and the fuse 22 contacts the plane 46 of the second silicone member 42, thereby increasing the contact area between the fuse 22 and the second silicone member 42, so that the fuse is better and more firmly attached to the heating element 1 through the second silicone member 42.

[0064] Specifically, one end surface of the third silicone member 43 has a third recess, and at least part of the temperature sensor 23 is disposed in the third recess. The heating element 1 is provided with a mounting hole 14, one end of the third silicone member 43 is fitted in the mounting hole 14, and the other end of the third silicone member 43 abuts against the third matching portion 33.

[0065] Specifically, the mounting hole 14 is provided on the aluminum plate, and the temperature sensor 23 is provided in the mounting hole 14 so as to be in direct contact with the stainless steel plate, thereby ensuring the reliability of the temperature conduction of the stainless steel plate to the temperature sensor 23, so as to detect the temperature of the heating element 1 in real time to control the start and stop of the heating element 1.

[0066] Optionally, thermal conductive silicone grease is applied to the outer surface of the third silicone member 43 to better transfer the heat on the stainless steel plate to the temperature sensor 23 , thereby ensuring the accuracy of the temperature sensor 23 in detecting the temperature of the stainless steel plate.

The strength of the same fixing member 3 is relatively high, and the uniformity of force is guaranteed, thereby reducing the risk of damage or reduced accuracy of the thermostat 21, the fuse 22 and the temperature sensor 23.

[0069] Specifically, the fixing member 3 is an annular member and is adapted to the heating pipe 12.

[0072] In the heating device of the embodiment of the utility model, the fixing member 3 is connected to the heating element 1 through a plurality of fasteners, thereby enhancing the firmness of the connection between the fixing member 3 and the heating element 1 and the stability of the heating device 100. Moreover, the plurality of fixing holes 36 are centrally symmetrically distributed or axially symmetrically distributed, thereby ensuring the uniformity of the force on the fixing member 3, thereby ensuring the uniformity of the force on the thermostat 21, the fuse 22 and the temperature sensor 23, and further improving the fitting effect of the thermostat 21, the fuse 22 and the temperature sensor 23 and the heating element 1.

Through the above arrangement, the uniformity of the force applied to the thermostat 21, the fuse 22 and the temperature sensor 23 when they are attached to the heating element 1 through the same fixing member 3 is further improved, and the risk of damage or reduced accuracy of the thermostat 21, the fuse 22 and the temperature sensor 23 is further reduced.
