[0004] The purpose of the utility model is realized by the following technical scheme:

[0008] The conductive wire is arranged in the threading channel, and when the conductive wire is connected to the heating floor, one end of the conductive wire is easily pulled back into the threading channel, so that the other end of the conductive wire is inconvenient to connect. Therefore, the wire clamping structure is arranged at least at one end of the threading channel to limit movement of the conductive wire, so that the connection head of the conductive wire is prevented from being pulled back into the threading channel.

[0009] Further, the wire clamping structure comprises at least three blocks, two adjacent blocks are arranged in a staggered manner, and a wire clamping channel is formed between the blocks and communicated with the threading channel.

[0012] In order to facilitate wiring between two adjacent heating floors, the length of the conductive wire is provided with a certain excess, so that the two ends of the conductive wire exceed the floor body by a certain length. After wiring is completed, the excess part of the conductive wire can be accommodated in the wire accommodating slot, avoiding the situation that the excess part of the conductive wire is pressed under the floor body, resulting in uneven laying of the heating floor or the wiring part being pressed and broken, causing the circuit to be broken.

DETAILED DESCRIPTION

[0033] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the related drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms, and is not limited to the embodiments described herein.

[0034] As Figure 1 and Figure 2As shown, the embodiment provides a heating floor, which comprises a floor body 1, a heating element 2, two conductive wires electrically connected with the heating element 2, and a thermal switch 5. The floor body 1 comprises a heating cavity 11, a wire passing channel 12 penetrating through the floor body 1 along the length direction of the floor body 1, and two wire connecting channels 16, which respectively communicate the heating cavity 11 with the two wire passing channels 12. The heating element 2 can be fixed in the heating cavity 11 by a pasting fixing mode. The heating element 2 can adopt a graphene heating sheet or a carbon fiber heating sheet. Both the graphene heating sheet and the carbon fiber heating sheet have the advantages of high material strength and good electrical conductivity, which can improve the heating capacity, thereby improving the energy utilization rate and the performance of the heating floor. The two conductive wires are a positive conductive wire 3 and a negative conductive wire 4, which are respectively arranged in the two wire passing channels 12. The positive conductive wire 3 and the negative conductive wire 4 are electrically connected with the positive and negative poles of an external circuit, respectively. The adapter wire of the heating element 2 and the thermal switch 5 are arranged in the wire connecting channel 16. In the embodiment, the thermal switch 5 is electrically connected with the heating element 2 and the positive conductive wire 3. The adapter wire of the heating element 2 and the thermal switch 5 are arranged in the wire connecting channel 16, which can ensure the flushness of the floor. In addition, the movement of the adapter wire and the thermal switch 5 can be limited by the gluing mode, so as to avoid the occurrence of circuit breaking. The thermal switch 5 can select a bimetallic sheet type thermal switch or a PCT thermal resistance type thermal switch. In the embodiment, the thermal switch 5 can select a bimetallic sheet type thermal switch. The bimetallic sheet inside the thermal switch 5 is composed of two metal materials with different thermal expansion coefficients. When the temperature changes, the bimetallic sheet will be bent and deformed due to the different expansion degrees of the two metals. When the temperature rises, the deformation of the active layer is greater than that of the passive layer. The bimetallic sheet will bend to the passive layer side, thereby pushing the switch contact to act, realizing the disconnection of the circuit. When the temperature decreases to the set reset temperature, the bimetallic sheet will return to the original state, the contact is automatically closed, and the circuit is re-conducted.

[0035] As Figure 2 and Figure 3As shown, the threading channel 12 is provided with a wire clamping structure 13 at least at one end to limit the movement of the conductive wire. When the conductive wire is threaded in the threading channel 12, and when the adjacent heating floor is connected, the conductive wire is prone to retreat into the threading channel 12 when pulled, which is not convenient for connecting the other end of the conductive wire. Therefore, the wire clamping structure 13 is provided at least at one end of the threading channel 12 to limit the movement of the conductive wire, so as to avoid the connection head of the conductive wire from retreating into the threading channel 12. In the embodiment, the wire clamping structure 13 is provided at both ends of the threading channel 12, and the wire clamping structure 13 includes at least three stoppers 131. Adjacent two stoppers 131 are arranged in a staggered manner, and a wire clamping channel 132 is formed between the stoppers 131 and communicates with the threading channel 12. The width of the wire clamping channel 132 is slightly larger than the diameter of the conductive wire, and the staggered arrangement of the stoppers 131 forms a bent wire clamping channel 132. The conductive wire continuously bends and extends in the wire clamping channel 132, and is not prone to move under stress, thereby achieving the purpose of limiting the movement of the conductive wire.

[0036] As shown in the drawings, Figure 2 The floor body 1 is provided with a wire containing notch 14 at both ends in the length direction, and the wire containing notch 14 communicates with the threading channel 12, and the depth of the wire containing notch 14 is greater than the depth of the threading channel 12. In order to facilitate the connection between the adjacent two heating floors, the length of the conductive wire is provided with a certain excess, so that the two ends of the conductive wire exceed the floor body 1 by a certain length. After the connection is completed, the excess part of the conductive wire can be accommodated in the wire containing notch 14, so as to avoid that the excess part of the conductive wire is pressed under the floor body 1, which causes the uneven laying of the heating floor, or the connection part is pressed and broken to cause the circuit to be broken. In addition, if the connection port is damaged, when there is no matching connection port, other larger size connection ports can be used for repair, which may cause the volume of the connection part to be larger. The depth of the wire containing notch 14 is designed to be greater than the depth of the threading channel, so as to provide a larger wire containing space and accommodate a larger connection part. The wire containing notch 14 is provided with a support block 15 at the middle position. The wire containing notch 14 is designed to be hollow, so its bearing capacity is weak. The support block 15 is arranged at the middle position, which can improve the support force and avoid the surface of the floor at this position from collapsing. In addition, the support block 15 can isolate the positive and negative conductive wire interfaces, which is safer. The size of the support block 15 is adapted to the size of the floor body 1 and the wire containing notch 14, so as to meet the support strength of the floor and the accommodation requirement of the connection head of the conductive wire.

[0037] As shown in the drawings, Figure 1 and Figure 2As shown, the floor body 1 has a first snap-fit ​​structure 17 and a second snap-fit ​​structure 18 on opposite sides along its width. Adjacent floor bodies 1 in the width direction are connected by the first snap-fit ​​structure 17 and the second snap-fit ​​structure 18. The first snap-fit ​​structure 17 and the second snap-fit ​​structure 18 are mortise and tenon structures. Adjacent floor bodies 1 are connected sequentially by the first snap-fit ​​structure 17 and the second snap-fit ​​structure 18, ensuring reliable connection, reducing construction difficulty, and improving construction efficiency. In other embodiments, such as... Figure 5 As shown, the floor body 1 has a third snap-fit ​​structure 19 and a fourth snap-fit ​​structure 120 on opposite sides along its length. The third snap-fit ​​structure 19 and the fourth snap-fit ​​structure 120 are mortise and tenon joints, and adjacent floor bodies 1 along the length are connected sequentially through the third snap-fit ​​structure 19 and the fourth snap-fit ​​structure 120. That is, snap-fit ​​structures are provided on all four sides of the floor body 1. The type and size of the snap-fit ​​structures are designed according to the actual situation. The first snap-fit ​​structure 17 and the second snap-fit ​​structure 18 can be the same type of snap-fit ​​structure as the third snap-fit ​​structure 19 and the fourth snap-fit ​​structure 120, or they can be different types of snap-fit ​​structures. The size of the snap-fit ​​structures can be the same or different, as long as a stable connection between the floor bodies is achieved. To reduce the difficulty of connecting the conductive wires of adjacent heated floor bodies, the conductive wires are provided with a first socket 7 and a first plug 6 at both ends. When connecting two adjacent heated floor bodies, the conductive wires can be quickly connected by plugging and fixing, ensuring a reliable and stable connection and further improving construction efficiency.

[0038] The main body of the flooring (1) is made of PETG (Polyethylene Terephthalate Glycol-Modified). Compared to other plastics, PETG has better insulation, higher impact resistance, and is less prone to cracking or shattering. It also has good temperature resistance, and does not easily soften or deform when subjected to high temperatures. The softening temperature of PETG is between 85-110℃, while the heating element generally heats at temperatures below 80℃. Therefore, the PETG flooring remains rigid and will not deform when heated.

The heating piece 2 can be fixed in the heating cavity by the pasting fixing mode, the heating piece 2 can adopt graphene heating sheet or carbon fiber heating sheet, the graphene heating sheet and the carbon fiber heating sheet have the advantages of high material strength and good conductivity, the heating capacity can be improved, and therefore the energy utilization rate and the performance of the heating floor are improved. The heating piece 2 is connected to the positive conductive wire 3 and the negative conductive wire 4 through the adapter wire, and the thermal sensitive switch 5 is connected between the heating piece 2 and the positive conductive wire 3, the thermal sensitive switch 5 is normally closed, can keep the passage in a certain temperature range, and the circuit can be disconnected when the temperature exceeds the set temperature, so that the temperature of the heating floor is controlled, when the object such as a carpet is covered on the floor in a certain area, the heat dissipation is poor, when the temperature of the heating floor laid in the area rises and exceeds the set temperature of the thermal sensitive switch 5, the thermal sensitive switch 5 is disconnected to stop the heating of the heating piece 2, the temperature of the heating floor is lowered, and the danger of overheating is avoided.
