Therefore, the heating tube needs to be cleaned regularly. The two ends of the heating tube are connected to the circuit through a fixed structure, which ensures the stability of the connection between the heating tube and the circuit. However, the fixed structure also makes it difficult to disassemble and assemble the heating tube, reducing the cleaning efficiency of the heating tube.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a detachable heating pipe connection mechanism and a heating device to improve the cleaning efficiency of the heating pipe.

[0006] The technical solution of the utility model is as follows:

[0007] A detachable heating pipe connection mechanism comprises: a first contact piece, connecting two ends of a heating pipe, the first contact piece being made of a conductive material; a spring piece, connected to a power supply circuit; and an elastic piece, sleeved on the spring piece; wherein the spring piece is bent to form a cavity with an opening, and the elastic piece is sleeved on the spring piece around the cavity; when the first contact piece extends into the cavity, the spring piece contacts the first contact piece from multiple directions around the first contact piece, thereby connecting the heating pipe to the power supply circuit.

[0008] A further technical solution is that it also includes a fixing plate, and both ends of the heating tube pass through the fixing plate from the same side.

[0009] A further technical solution is that a second contact piece is further provided on the fixing plate, and the second contact piece and the first contact piece are on the same side of the fixing plate.

[0011] A further technical solution is that a slot is provided on the lower fixing plate, a step is formed in the slot, and the spring sheet is arranged in the slot and abuts against the step.

[0012] A further technical solution is that a limiting groove section is provided at one end of the clamping slot close to the first contact piece, and an inner wall of the limiting groove section is arranged corresponding to the shape of the first contact piece.

[0013] A further technical solution is that one end of the spring sheet close to the fixing sheet is bent inward to form a fitting portion; and the cavity at the fitting portion is reduced in size.

[0014] A further technical solution is that the fitting portion is close to one end of the fixing plate and is bent outward to form a bent portion; and the bent portion transitions into the cavity.

[0015] The heating device comprises a box body and a detachable heating tube connection mechanism, wherein the heating tube is arranged inside the box body, the spring sheet is arranged outside the box body, a through hole is opened on the box body, and the first contact member is inserted into the spring sheet through the through hole.

[0016] A further technical solution is that it further comprises a protective cover, wherein the protective cover is covered on the box body and has heat dissipation holes; and the spring sheet is arranged in the protective cover.

[0017] The beneficial technical effects of the utility model are as follows:

[0029] Embodiment 1

[0030] Figure 1 A three-dimensional structural schematic diagram of a detachable heating pipe connection mechanism in a first embodiment of the utility model is shown. Figure 2 The diagram shows a structural diagram of a detachable heating pipe connection mechanism in a connected state in a first embodiment of the present invention. Figure 3 The schematic diagram of the structure of the detachable heating pipe connection mechanism in the first embodiment of the present invention in the separated state is shown. Figure 1 , Figure 2 and Figure 3 , a detachable heating tube connection mechanism includes a first contact piece 2, a spring piece 7 and an elastic piece 71. The first contact piece 2 connects the two ends of the heating tube 1. The first contact piece 2 is made of conductive material. The spring piece 7 is connected to the power supply line. Among them, the spring piece 7 is bent to form an open cavity 73, and the elastic piece 71 is sleeved on the spring piece 7 around the cavity 73. The elastic piece 71 elastically squeezes the spring piece 7. When the first contact piece 2 is inserted into the cavity 73, the first contact piece 2 will push the spring piece 7 to expand outward, and the elastic piece 71 squeezes the spring piece 7 inward, so that the spring piece 7 always fits the first contact piece 2, thereby improving the stability of the connection between the spring piece 7 and the first contact piece 2, and further improving the current transmission efficiency. When the first contact piece 2 extends into the cavity 73, the spring piece 7 contacts the first contact piece 2 from multiple directions around the first contact piece 2, and the heating tube 1 is connected to the power supply line. The spring piece 7 is coated on the first contact piece 2, which increases the contact area between the spring piece 7 and the first contact piece 2, ensures the stability of the connection between the spring piece 7 and the first contact piece 2, and improves the current transmission efficiency.

[0031] The specific structure of the spring piece 7 and the fixing piece 4 is described below:

[0032] Please refer to Figure 2 The spring sheet 7 is close to one end of the fixing sheet 4 and is bent inward to form a fitting portion 74; the cavity 73 at the fitting portion 74 is reduced. The outer dimensions of the first contact member 2 and the second contact member 3 are larger than the reduced dimensions of the cavity 73, ensuring that when the first contact member 2 and the second contact member 3 extend into the cavity 73, the spring sheet 7 at the fitting portion 74 contacts the first contact member 2 and the second contact member 3.

[0033] Please refer to Figure 3 , and also includes a fixing plate 4, through which both ends of the heating tube 1 pass from the same side. Both ends of the heating tube 1 are fixed to the fixing plate 4 by riveting. The fixing plate 4 completes the fixing of the heating tube 1, thereby limiting the position of the first contact member 2. The number of the spring plates 7 corresponds to the number of the first contact members 2, and the position of the spring plates 7 corresponds to the position of the first contact member 2, so that the first contact member 2 can be accurately plugged in and out of the corresponding spring plates 7.

[0034] The end of the fitting portion 74 close to the fixing plate 4 is bent outward to form a bent portion 72; the bent portion 72 transitions into the cavity 73, which facilitates the insertion of the first contact member 2 into the cavity 73 of the spring sheet 7. The first contact member 2 first contacts the bent portion 72 and is inserted into the cavity 73 along the bent portion 72, thereby expanding the insertion range of the cavity 73. At the same time, the bent portion 72 abuts against the elastic member 71, and also limits the movement of the elastic member 71, thereby preventing the elastic member 71 from falling off the spring sheet 7.

[0035] Please refer to Figure 1 The fixing plate 4 is also provided with a second contact member 3, the second contact member 3 and the first contact member 2 are on the same side of the fixing plate 4, and the second contact member 3 and the first contact member 2 are arranged in the same direction. Correspondingly, a spring piece 7 is provided to cooperate with the second contact member 3. The position of the spring piece 7 corresponds to the position of the second contact member 3. The second contact member 3 is connected to the ground wire after the spring piece 7 is inserted to lead out the dangerous current generated during the operation of the heat pipe 1.

[0036] The first contact member 2 and the second contact member 3 may be cylindrical or polygonal. When the first contact member 2 and the second contact member 3 are cylindrical, the inner wall of the cavity 73 formed by bending the spring sheet 7 may also have an arc to better fit the surface of the first contact member 2 and the second contact member 3. When the first contact member 2 and the second contact member 3 are polygonal cylinders, the inner wall of the cavity 73 formed by bending the spring sheet 7 may also be composed of multiple planes to better fit the surface of the first contact member 2 and the second contact member 3.

[0037] The specific structure of the upper fixing plate 5 and the lower fixing plate 6 is described below:

[0038] Please refer to Figure 1 and Figure 3 , further comprising an upper fixing plate 5 and a lower fixing plate 6, with a spring sheet 7 disposed between the upper fixing plate 5 and the lower fixing plate 6. A slot 61 is provided on the lower fixing plate 6, and a step 62 is formed on the slot 61. The spring sheet 7 is disposed in the slot 61 and abuts against the step 62. The outer surface of the spring sheet 7 abuts against the step 62 to limit the position of the spring sheet 7 in the slot 61. When the first contact 2 and the second contact 3 are inserted into the spring sheet 7, they can be quickly positioned through the step 62, thereby improving the connection efficiency of the heat pipe connection mechanism.

[0039] A limiting groove section 63 is provided at one end of the slot 61 close to the first contact piece 2, and the inner wall of the limiting groove section 63 is set corresponding to the shape of the first contact piece 2 to quickly locate the position of the first contact piece 2 or the second contact piece 3 extending into the slot 61, so that the first contact piece 2 or the second contact piece 3 is aligned with the spring piece 7.

[0040] The specific working process of the utility model is as follows:

[0041] When the heating tube 1 is connected to the power line, the operator moves the fixing plate 4 so that the first contact member 2 and the second contact member 3 are respectively aligned with the cavities 73 of the spring piece 7, and then pushes the fixing plate 4 to insert the first contact member 2 and the second contact member 3 into different cavities 73. The first contact member 2 and the second contact member 3 contact the spring piece 7, and under the elastic force of the elastic member 71, the spring piece 7 applies a certain pressure to the first contact member 2 and the second contact member 3, the power line is connected to the power supply, the current is transmitted, and the heating tube 1 is connected to the power line.

[0042] When the heating tube 1 is removed from the power line, the power line is disconnected from the power supply, and the operator moves the fixing plate 4 in the reverse direction to pull out the first contact member 2 and the second contact member 3 from the cavity 73. After the heating tube 1 is completely pulled out, the heating tube 1 is removed from the power line. Then the heating tube 1 can be cleaned.

By moving the fixing plate 4, the first contact piece 2 and the second contact piece 3 can be easily inserted into the cavity 73, or the first contact piece 2 and the second contact piece 3 can be pulled out from the cavity 73 to connect or remove the heating tube 1 from the power line. The fixing plate 4, the heating tube 1, the first contact piece 2 and the second contact piece 3 can be easily removed from the box body 8, so as to facilitate the cleaning of the heating tube 1 and the box body 8, improve the cleaning efficiency of the heating tube 1, and thus improve the performance and user experience of the heating device.

[0045] The box body 8 is composed of a bottom plate 82, a side plate 81 and a connector 83. A through hole 811 is provided on the side plate 81. Two side plates 81 are provided, and the two side plates 81 are provided on the opposite sides of the bottom plate 82. A connector 83 is provided between the two side plates 81. The connector 83 connects the two side plates 81 at the same time. The side plates 81 and the connector 83 surround and protect the heating pipe 1. The connector 83 can be rod-shaped or plate-shaped, and the connector 83 and the side plate 81 are plugged.

[0046] Further, the heating device also includes a protective cover 9, which is covered on the box body 8. Exemplarily, the protective cover 9 is in two groups. The protective cover 9 is covered on the left and right ends of the box body 8. A support leg is provided at the bottom of the protective cover 9, and the two protective covers 9 support the box body 8.
