For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0031] The utility model provides a heating coil disk assembly 100 for a fire boiler.

[0032] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] In the embodiment of the present utility model, Figures 1 to 3 As shown, the fire boiler heating coil disk assembly 100 includes a pot body rack 10, a coil 20, a magnetic strip 30, a sensor assembly 40 and a clamping cover 50, wherein a circular hole 121 is provided in the middle of the pot body rack 10, and a plurality of snap-in grooves 111 evenly distributed around the circumference are provided at the bottom edge of the pot body rack 10; the coil 20 is arranged at the bottom of the pot body rack 10; there are a plurality of magnetic strips 30 radially arranged at the bottom of the coil 20, and one end of the magnetic strip 30 is clamped into the snap-in groove 111; the sensor assembly 40 is arranged in the middle of the pot body rack 10, and the sensor assembly 40 has a sensing component 41, and the top end of the sensing component 41 extends out of the circular hole 121 and slides up and down to fit; the clamping cover 50 is detachably arranged at the bottom of the pot body rack 10, and clamps the sensor assembly 40 and the other end of the magnetic strip 30.

[0034] In the present invention, the coil 20 is wound with a wire having a square cross section, and the inner and outer coils can be closely fitted with the wire, and the coil 20 can be closely attached to the bottom of the pot body frame 10 to increase the contact area. The coil 20 is fixed to the bottom of the pot body frame 10 by glue. The magnetic strip 30 is radially arranged on the side of the coil 20 away from the pot body frame 10, and one end of the magnetic strip 30 is inserted into the clamping groove 111 at the bottom of the pot body frame 10. After the sensor assembly 40 is installed at a specific position of the pot body, the clamping cover 50 is installed. The clamping cover 50 has a limiting effect on the sensor assembly 40 on the one hand, limiting the distance that the sensor assembly 40 can slide up and down to prevent it from falling off, and on the other hand, it has a clamping effect on the other end of the magnetic strip 30, that is, both ends of the magnetic strip 30 are clamped, so as to achieve fixation. When the magnetic strip 30 is clamped, the magnetic strip 30 also has a clamping effect on the coil 20 to prevent the coil 20 from falling off. The sensor assembly 40 in the present invention is used to monitor problems with the pot body and then feed back to the controller. When a pot is placed on the heating coil disk assembly 100 of the fire boiler, the sensing component 41 extends out of the circular hole 121, that is, protrudes from the top of the pot body disk rack 10. When a pot is placed, the gravity of the pot causes the sensing component 41 to slide downward, and the sensing component 41 contacts the bottom of the pot to achieve temperature monitoring.

[0035] The technical solution of the utility model includes a pot body frame 10, a coil 20, a magnetic strip 30, a sensor assembly 40 and a clamping cover 50. The coil 20 and the magnetic strip 30 are located on the same side of the pot body frame 10. The magnetic strip 30 is located at the bottom of the coil 20 and one end of the magnetic strip 30 extends into the clamping groove 111 at the bottom of the pot body frame 10. The sensor assembly 40 is arranged in the middle of the pot body frame 10. The clamping cover 50 compresses the sensor assembly 40 while also compressing the other end of the magnetic strip 30. Since the clamping cover 50 is used to fix the sensor assembly 40 and the magnetic strip 30 at the same time, the technical problems of high cost, low efficiency and complicated process existing in the prior art are effectively solved, thereby achieving the technical effects of structural optimization, convenient disassembly and assembly, cost reduction and improved production efficiency.

[0036] In the embodiments of the present invention, Figure 3 and Figure 4As shown, the pot body frame 10 includes a pot body frame 11 and a pot bottom frame 12 of split design, a round hole 121 is provided on the pot bottom frame 12, a snap-in groove 111 is provided on the bottom of the pot body frame 11, and a pressing cover 50 is detachably connected to the pot bottom frame 12 to press the coil 20 and the magnetic strip 30 to the bottom of the pot bottom frame 12. The utility model transforms the pot body frame 10 from an integrated design to a split design, because when the coil disk assembly is working, the temperature generated by the pot body and the pot body is different, and the split design allows different materials to be selected according to different heating temperatures, the pot body frame 11 and the pot bottom frame 12 are both plastic parts, and are fixed by snap-in connection during assembly, and according to the principle of thermal expansion and contraction of plastics, that is, one is a cold part and the other is a hot part during assembly, and a tight fit is achieved after clamping.

[0037] In the embodiments of the present invention, Figure 1 and Figure 3 As shown, the induction component 41 is slidably arranged on the pot bottom plate frame 12 through the spring 42, one end of the spring 42 abuts against the pot bottom plate frame 12, and the other end of the spring 42 abuts against the pressing cover 50. When the pot is placed on the top of the pot bottom plate frame 12, the induction component 41 slides downward and compresses the spring 42, and when the pot is away from the pot bottom plate frame 12, the spring 42 resets and pushes the induction component 41 to slide upward.

[0038] In the embodiments of the present invention, Figure 4 and Figure 6 As shown, the compression cover 50 is connected to the pan bottom frame 12 by threaded fasteners. A plurality of threaded columns are provided at the bottom of the pan bottom frame 12. When the compression cover 50 is positioned, the threaded portion extends out of the bottom of the compression cover 50 and is connected to the threaded column by a nut, thereby assembling the compression cover 50.

In addition to achieving the anti-interference effect, the protruding portion 32 also plays an auxiliary positioning role during the assembly process, so that the magnetic strip 30 is evenly distributed after installation, thereby improving the effect of electromagnetic heating.

[0040] In the embodiments of the present invention, Figure 4As shown, the bottom edge of the pot body frame 11 is provided with a plurality of connection holes 112 evenly distributed around the circumference, the connection holes 112 and the snap-in grooves 111 are alternately arranged, the bottom of the pot body frame 11 is provided with a connection column 122, the end of the connection column 122 is provided with a snap-in member 123, and the snap-in member 123 snaps with the connection hole 112. After the snap-in is completed, the snap-in member 123 can also be hot-pressed by high-temperature hot pressing to change its shape to achieve the fixation between the pot body frame 11 and the pot body frame 10 to avoid loosening.
