Description

Technical Field

[0001] The present invention relates to the technical field of novel electric heating materials, and in particular to a heating film with convenient hole opening and a heating paving module. Background Art

[0002] Graphene has good conductivity, fast electron mobility, fast heating speed, and is more energy-saving and environmentally friendly. In addition, the heating principle of graphene is far-infrared heating, which has a good health care effect on the human body. Therefore, graphene heating ink film has broad applications in many fields, especially in home decoration occasions such as heating tabletops, heating floors, heating walls, and electric heating murals.

[0003] However, these existing products typically apply heating ink films in sheets. When localized areas require protection (e.g., avoiding wall switches or outlets), the entire area must be left uncovered, or separate heating ink films of varying specifications must be installed along separate lines. Furthermore, if a sheet of heating film is partially covered, heat cannot be dissipated quickly, leading to localized overheating. This can render the entire sheet unusable and even pose safety concerns. Summary of the Invention

[0004] The purpose of the present invention is to provide a heating film that is easy to open holes in order to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The technical solutions adopted to solve the above technical problems are:

[0006] A heating film that is easy to open holes, comprising: a film body, wherein the film body is provided with a positive line and a negative line arranged on the left and right, a plurality of mutually unconnected heating block groups are arranged front and back between the positive line and the negative line, a plurality of mutually unconnected heating units are arranged on the left and right of the heating block group, and the front and rear ends of the heating block group are covered with electrode connecting lines, and two adjacent electrode connecting lines are respectively connected to the positive line or the negative line.

[0007] The heating film that is easy to open holes provided by the present invention has at least the following beneficial effects: the front and rear ends of the heating block group are connected to the positive line and the negative line through the electrode connecting line, so that when the positive line and the negative line are energized, the front and rear ends of the heating block group have a point pressure difference, thereby realizing the heating function. Adjacent heating block groups and adjacent heating units are not connected to each other and have gaps, so that the heating film can be hollowed out and opened with heating units as units, so that the heating film can match a specific shape when paved, and meet complex air avoidance requirements. The heating film that is easy to open holes of the present invention connects multiple heating units arranged vertically and horizontally to the positive line and the negative line through electrode connecting lines, so that the heating units can be cut separately to realize opening holes, and the opening of holes does not affect the normal operation of the remaining heating units.

[0008] As a further improvement of the above technical solution, the positive and negative lines are parallel to each other and extend in the front-to-back direction. Through the above technical solution, the positive and negative lines can supply power and generate heat for the heating unit therebetween.

[0009] As a further improvement to the above technical solution, the electrode connecting wire has a connection end connected to the positive or negative wire, and the connection end extends in a fishbone shape in the front-to-back direction. With the above technical solution, the fishbone-shaped extension of the connection end increases the contact area between the electrode connecting wire and the positive or negative wire, making it less likely to disconnect.

[0010] As a further improvement to the above technical solution, the electrode connection line includes two connecting sub-lines, each of which covers the edges of two adjacent heating block groups. Through the above technical solution, the two connecting sub-lines cover the edges of two heating block groups, so that the heating units of the corresponding heating block group are connected to the positive line or the negative line, avoiding the electrode connection line completely covering the area between two adjacent heating block groups, saving materials.

[0011] As a further improvement to the above technical solution, a connecting bridge is further provided between the two connecting sub-wires, with the two ends of the connecting bridge respectively connected to the two connecting sub-wires. The number and position of the connecting bridges can be set according to the hole requirements. Through the above technical solution, the two connecting sub-wires are respectively connected to the ends of the two heating block groups, and the ends of the two connecting sub-wires are connected to the positive line or the negative line. The connecting bridge connects the two connecting sub-wires at all positions except the end positions connected to the positive line or the negative line. When the heating unit is hollowed out and a hole is opened, the disconnected connecting sub-wire can still be connected to another connecting sub-wire through the connecting bridge to avoid power outage.

[0012] The present invention also provides a heating paving module, comprising: an outer shell, a filling layer, and the above-mentioned heating film; the outer shell cover is arranged on the outside of the filling layer, and the heating film is arranged between the outer shell and the filling layer.

[0013] The heating paving module provided by the present invention has at least the following beneficial effects: the outer shell and the filling layer can protect the heating film therebetween, so that the heating paving module can meet the paving requirements and can be directly buried in the wall or floor during paving.

[0014] As a further improvement of the above technical solution, the shapes of the shell and the filling layer are consistent with the shape of the heating film. Through the above technical solution, the shapes of the heating film, the filling layer and the shell correspond to each other, which facilitates the avoidance of openings and laying.

[0015] As a further improvement to the above technical solution, the filling layer is made of polyurethane and the shell is made of engineering plastic. Through the above technical solution, both the shell and the filling layer have good strength and performance, and are lightweight, greatly reducing the transportation cost of the heating pavement module.

[0016] As a further improvement to the above technical solution, the heating paving module further includes a conductive wire connected to the positive and negative wires, with both ends of the conductive wire having connectors located outside the housing. With the above technical solution, different heating paving modules can be connected to each other via the conductive wires, or connected to the power bus via the conductive wires, facilitating installation.

[0017] As a further improvement to the above technical solution, the conductive wire is a rubber wire, further connected to a temperature control element. Through this technical solution, the rubber wire is made of high-temperature-resistant, high-strength materials and processed through a special process, resulting in high and low-temperature resistance. The temperature control element can control the on and off of the heating paving module, preventing burnout due to localized overheating, significantly extending the module's service life.

[0029] Reference Figures 1 to 5 The heating paving module of the present invention is implemented as follows:

[0030] A heating paving module includes: a shell 100, a filling layer 200, a conductive wire 300 and a heating film 400.

[0031] The outer shell 100 is disposed on the outer side of the filling layer 200, and the heating film 400 is disposed between the outer shell 100 and the filling layer 200. The middle section of the conductive wire 300 is disposed within the filling layer 200 and connected to the heating film 400. The two ends of the conductive wire 300 are exposed on both sides of the outer shell 100. The two sides of the outer shell 100 are provided with a clip 110 for inserting the conductive wire 300. The conductive wire 300 is clipped into the clip 110, and the two ends of the conductive wire 300 extend outward from the two clips 110.

[0032] In this embodiment, the shell 100 is a heat-resistant engineering plastic product. Engineering plastics have excellent comprehensive properties, high rigidity, low creep, high mechanical strength, good heat resistance, good electrical insulation, and can be used for a long time in harsh chemical and physical environments. The shell 100 is made of engineering plastic, which makes the overall weight of the heating paving module light, and it will not be corroded when covered or even immersed in cement during paving. The filling layer 200 is made of polyurethane material, and is directly formed and cured on the inner side of the shell 100 through a mold during production. In this embodiment, the filling layer 200 is a hard polyurethane plastic, which has the advantages of light weight, sound insulation, excellent thermal insulation performance, chemical resistance, good electrical properties, easy processing, and low water absorption. In addition, polyurethane foam plastics also have excellent processability, adhesion, thermal insulation and other properties. It is an excellent performance buffer material and is very suitable for use in the filling layer 200 of the heating paving module.

[0033] The side of the heating film 400 close to the housing 100 is the upper side, and the side of the heating film 400 close to the filling layer 200 is the lower side. In some embodiments, a reflective film is further provided on the lower side of the filling layer 200. The reflective film blocks the heat of the heating film 400, preventing it from dissipating downward, thereby improving energy efficiency.

[0034] The heating film 400 is provided with a positive line 410 and a negative line 420 arranged on the left and right sides. The positive line 410 and the negative line 420 are both copper wires and are respectively provided on the left and right ends of the heating film 400. The positive line 410 and the negative line 420 are parallel to each other and extend in the front-to-back direction.

[0035] Multiple heating block groups are provided between the positive and negative lines 410 and 420. The heating block groups are arranged in a front-to-back direction and are not connected to each other. The heating block groups are provided with multiple heating units 431. The heating units 431 are arranged in a left-to-right direction and are not connected to each other.

[0036] Electrode connection lines are provided between the heating block groups. Of the two adjacent electrode connection lines, one is connected to the positive line 410 and the other is connected to the negative line 420. The electrode connection lines cover the edges of the heating block groups on both sides of the front and back. The front and back ends of each heating block group can be connected to the positive line 410 and the negative line 420 respectively through the electrode connection lines, so that when the positive line 410 and the negative line 420 are energized, a voltage can be formed at the front and back ends of the heating block group, so that the conductive ink in the heating unit 431 is energized and generates heat.

[0037] A horizontal isolation zone 450 extending left and right is formed between adjacent heating block groups, and a longitudinal isolation zone 432 extending front and back is formed between adjacent heating units 431. When holes need to be drilled in the heating film 400, the corresponding heating units 431 are hollowed out along the horizontal isolation zone 450 and longitudinal isolation zone 432 surrounding the heating units 431 to achieve the holes in the heating film 400.

[0038] In this embodiment, the electrode connection line is silver-plated and printed. The cost of the electrode connection line is relatively high. Completely covering the transverse isolation strip 450 between the heating block groups would also be costly. Therefore, in a further embodiment, the electrode connection line includes two connecting sub-lines 441. The two connecting sub-lines 441 respectively cover the edges of two adjacent heating block groups.

[0039] The connecting sub-line 441 extends in the left-right direction. The two ends of the connecting sub-line 441 are the connecting end and the distal end. The connecting end is connected to the positive line 410 or the negative line 420.

[0040] In order to save materials and reduce costs while meeting the electrical conductivity requirements, in some embodiments, the width of the connecting sub-line 441 decreases from the connecting end to the distal end. That is, the closer to the connecting end, the wider the connecting sub-line 441.

[0041] In order to avoid poor contact or even disconnection between the connection end and the positive electrode line 410 or the negative electrode line 420 , the connection end is extended in a fishbone shape in the vertical direction.

[0042] To prevent the connection sub-lines 441 at the front and rear ends of the corresponding heating unit 431 from being disconnected after the heating film 400 is perforated, thereby affecting the adjacent heating units 431 that have not been hollowed out, in a further embodiment, a connection bridge 442 is provided between the two connection sub-lines 441. The two ends of the connection bridge 442 are respectively connected to the two connection sub-lines 441.

[0043] The number and position of the connecting bridges 442 can be set according to the hole requirements. Figure 3 As shown, if the hole opening requirement is only for a single heating unit 431 and no holes are required for adjacent heating units 431, the connecting bridge 442 can be provided between two adjacent heating units 431. In particular, since the hole opening will not damage the positive and negative cables 410 and 420, the connecting bridge 442 is not required between the two heating units 431 near the connection end.

[0044] If holes need to be cut in adjacent heating units 431, the connecting bridge 442 is preferably arranged to cover the intersection of the longitudinal isolation strip 432 and the transverse isolation strip 450. The front and rear ends of the connecting bridge 442 both contact the corners of the two adjacent heating units 431 on the left and right. After cutting and opening holes along the longitudinal isolation strip 432 and the transverse isolation strip 450, the heating units 431 adjacent to the opening area can still be connected to each other through the connecting bridge 442 that has not been completely cut.

[0045] In some embodiments, the opening range can be set between adjacent transverse isolation strips 450, and the edge of the opening range does not extend along the longitudinal isolation strip 432 or the transverse isolation strip 450. If the opening is made within the range of the heating unit 431 and the connecting bridge 442 is not cut, each heating unit 431 can still be powered, but the heating effect of the cut heating unit 431 is very poor; and the edge of the opening range has high temperature instability, which is prone to local overheating and low safety.

[0046] The shapes of the housing 100 and the filling layer 200 are consistent with the shape of the heating film 400. Figure 1 As shown, in some embodiments, the heating film 400 is rectangular. In other embodiments, as shown Figure 5 As shown, if the heating film 400 is opened in a local area, the shapes of the shell 100 and the filling layer 200 are also opened at corresponding positions.

[0047] To prevent cement corrosion and extend its service life, the conductive wire 300 is a rubber conductor with a rubber outer layer. The ends of the conductive wire 300 are equipped with corresponding male and female plugs 310 and 320, respectively. During use, two different heating pavement modules can be quickly connected through the male and female plugs 310 and 320. The conductive wire 300 is equipped with a live and neutral wire, which connect to the positive and negative wires 410 and 420, respectively.

[0048] A temperature control element 330 is also provided between the live wire and the positive wire 410. The temperature control element 330 is used to prevent the heating paving module from overheating. When the heating floor or heating wall paved with the heating paving module is partially covered and the local temperature is too high, the temperature control element 330 detects that the temperature has reached the preset limit temperature and disconnects the live wire and the positive wire 410, so that the corresponding heating paving module stops working until the temperature drops to the preset restart temperature. For example: the normal operating temperature range of the heating paving module is 25°C to 45°C. When the temperature control element 330 detects that the real-time temperature reaches the limit temperature of 50°C, the power supply to the heating paving module is disconnected. After waiting for the temperature to drop to the restart temperature of 30°C, the temperature control element 330 reconnects the live wire and the positive wire 410, so that the heating paving module restarts and heats up.

[0049] In particular, the heating temperature of the heating paving module is generally adjusted according to the real-time needs of the user, and the limit temperature and the restart temperature are preferably set in real time according to the real-time heating temperature gear. The limit temperature is higher than the heating temperature, and the restart temperature is not higher than the heating temperature. For example, when the user adjusts the heating paving module to keep it working at 40°C, the limit temperature and the restart temperature can be set to 50°C and 30°C; when the user adjusts the heating paving module to keep it working at 45°C, the limit temperature and the restart temperature can be set to 55°C and 35°C; when the user adjusts the heating paving module to keep it working at 30°C, the limit temperature and the restart temperature can be set to 38°C and 22°C.
