[0027] Specifically, in this embodiment, the solution mainly includes a mounting housing 1, inside which two parallel heater bodies 2 are arranged; to avoid exposing the electronic control components to the external environment, an assembly gap is reserved between the two heater bodies 2; a mounting side plate 3 is installed on the left and right sides and the top and bottom sides of the assembly gap; these four side plates tightly enclose each other to form a closed and stable mounting cavity, providing the electronic control components with a working environment free from external interference;

[0028] The upper end face of the installation cavity is designed to be open, which not only facilitates the installation of the electric control assembly, but also simplifies the subsequent maintenance work; fasteners are arranged in the installation cavity to ensure the stability of the installation of the electric control assembly; the fasteners are composed of a series of return springs 4 equidistantly distributed on the opposite side of the installation side plate 3; the return springs 4 not only provide the electric control assembly with necessary elastic support, but also play an excellent buffering and damping role when the electric control assembly is subjected to external force impact or temperature change;

[0030] As shown in the further preferred embodiment of the utility model, Figure 1 The installation shell 1 is symmetrically provided with two groups of connecting springs 6 adjacent to the two sides of the installation cavity, the two groups of connecting springs 6 are both provided with dampers, and the ends of the two groups of connecting springs 6 away from the installation shell 1 are both provided with connecting buckles 7.

[0031] In this embodiment, the connecting buckle 7 is designed to be stably connected with the external structure, and the connecting spring 6 is provided with an elastic structure for the connecting buckle 7; the elastic structure enables the connecting buckle 7 to have certain buffering and adaptive capacity when connected with the external structure, so that the connecting buckle 7 and the external structure are tightly and stably connected.

[0032] As shown in the further preferred embodiment of the utility model, Figure 1 The installation cavity is provided with an installation cover 8, and the installation cover 8 is provided with a clamping groove hole 9 for connection at each corner position.

[0033] In this embodiment, the installation cover 8 is used to close the installation cavity to protect the internal electric control assembly, and the clamping groove hole 9 is provided at each corner position of the installation cover 8; the clamping groove hole 9 is designed to be connected with the connecting buckle 7, the connecting buckle is connected with the clamping groove hole 9, and the elastic setting of the connecting spring 6 enables the connecting buckle to be in the clamping groove hole 9, so that the installation cover 8 can be firmly fixed on the installation cavity.

[0034] As shown in the further preferred embodiment of the utility model, Figure 1 The installation cover 8 is provided with a sealing strip 10 on the opposite side of the installation shell 1.

[0035] In the embodiment, the mounting cover 8 is designed to seal the mounting cavity to protect the electric control components inside from external interference; at four corner positions of the mounting cover 8, card slot holes 9 are formed; the main function of the card slot holes 9 is to cooperate with the connecting buckles 7, and the elastic setting of the connecting spring 6 gives the connecting buckles 7 certain elasticity and adaptability, so that the connecting buckles 7 can be smoothly inserted into the card slot holes 9 and firmly fixed on the mounting cover 8 under the action of the connecting buckles 7; the elastic setting not only ensures that the mounting cover 8 can be closely attached to the mounting cavity to prevent the invasion of external pollutants such as dust and moisture, but also makes the mounting and dismounting process more convenient and flexible.

[0036] As shown in the further preferred embodiment of the utility model, Figures 1-5 Two groups of heat dissipation through holes 11 are formed on the upper surface of the mounting cover 8.

[0037] In the embodiment, the main function of the heat dissipation through holes 11 is to enhance the heat dissipation performance of the heater, so as to ensure that the heat generated by the electric control components during the working process can be timely and effectively dissipated, thereby avoiding the occurrence of overheating and ensuring the stable operation of the heater.

[0038] As shown in the further preferred embodiment of the utility model, Figure 5 The mounting shell 1 is provided with an overheat protection device 12, the overheat protection device 12 comprises a fuse, one end of the fuse is connected with the circuit of the heater main body 2, the other end is connected with the external power supply through a wire, and a protection shell is arranged outside the fuse.

[0039] In the embodiment, one end of the fuse is closely connected with the circuit of the heater main body 2, responsible for stably transmitting the electric energy of the external power supply to the heater main body 2 to drive it to work normally; the other end is connected with the external power supply through a special wire, ensuring the integrity and continuity of the electric energy transmission.

[0040] In order to further enhance the protection effect of the fuse, a firm protection shell is additionally arranged outside the fuse; the protection shell not only provides additional physical protection for the fuse to prevent it from being damaged due to external force or environmental factors, but also can isolate external heat to a certain extent, so as to ensure that the fuse can work in a more stable and safe environment.

[0041] When the heater main body 2 is overheated due to some reasons such as current overload and high environmental temperature, the metal conductor inside the fuse will gradually soften and eventually melt due to heat; this melting process will quickly cut off the circuit connection between the heater main body 2 and the external power supply, thereby effectively preventing the current from continuing to flow into the heater main body 2 and avoiding the safety hazards such as fire and short circuit that may be caused by overheating.

[0042] The utility model further preferable embodiment as shown in the figure, the inside of mounting shell 1 is provided with electric control board 13, electric control board 13 and heater main body 2 between electric connection. Figure 5

[0043] In this embodiment, when the ambient temperature or the working temperature of the heater main body 2 is lower than the set value, the electric control board 13 sends a heating instruction to the heater main body 2 to start or increase the heating power to increase the temperature. On the contrary, when the temperature reaches or exceeds the set value, the electric control board 13 sends an instruction to the heater main body 2 in time to reduce the heating power or stop heating to keep the temperature within the set range, realizing accurate control of the working temperature of the heater main body 2, improving the heating efficiency and safety of the heater main body 2, and providing users with more comfortable and convenient use experience.

[0044] The utility model further preferable embodiment as shown in the figure, Figure 1 The outer diameter size of the connecting buckle 7 is matched with the inner diameter size of the clamping groove hole 9.

[0045] In this embodiment, the matched size can prevent loosening caused by vibration or external force. The close fit ensures that the electric control assembly can maintain a stable connection state during long-term use, avoiding performance degradation or safety hazards caused by loosening.

[0046] Working principle: two heater main bodies 2 are designed inside the mounting shell 1, and an assembly gap is reserved between them to install the electric control assembly. In order to avoid direct exposure of the electric control assembly to the external environment, tightly enclosing mounting side plates 3 are installed on the left and right sides and the upper and lower sides of the assembly gap. The four mounting side plates 3 form a closed and stable mounting cavity, providing an interference-free working environment for the electric control assembly.

[0047] The upper end face of the mounting cavity is designed as an open structure, which not only facilitates the installation process of the electric control assembly, but also simplifies the subsequent maintenance work. In order to ensure the stability of the electric control assembly in the mounting cavity, fasteners are configured in the mounting cavity. The fasteners are composed of return springs 4 distributed equidistantly on the opposite side of the left and right mounting side plates 3. They not only provide necessary elastic support for the electric control assembly, but also play an excellent buffering and shock-absorbing role when the electric control assembly is subjected to external force impact or temperature change.

[0048] ​In order to further enhance the damping effect, a damper is embedded in each return spring 4, which significantly reduces the vibration and noise of the electric control assembly during operation; each side of the return spring 4 away from the mounting side plate 3 is connected with a fastening pad 5, which not only uniformly transmits the elastic force of the return spring 4 to the electric control assembly, but also effectively increases the friction by the anti-slip pattern on the outer surface, preventing displacement of the electric control assembly when vibrating or changing temperature.

[0049] In order to close the mounting cavity and protect the internal electric control assembly, a mounting cover 8 is provided on the mounting cavity; four corner positions of the mounting cover 8 are provided with clamping slot holes 9, which are designed to be connected with the connecting buckle 7; the connecting buckle 7 is elastically arranged through the connecting spring 6, which can be smoothly inserted into the clamping slot hole 9 and firmly fixed on the mounting cover 8 under the action of the connecting buckle 7; this elastic arrangement not only ensures that the mounting cover 8 can be tightly attached to the mounting cavity, preventing the intrusion of external pollutants such as dust and moisture, but also makes the installation and removal process more convenient and flexible.

[0050] Meanwhile, the mounting cover 8 is provided with heat dissipation through holes 11 to enhance the heat dissipation performance of the heater, ensuring that the heat generated by the electric control assembly during operation can be timely and effectively dissipated, thereby avoiding overheating and ensuring stable operation of the heater.

[0051] In addition, a fuse is provided in the mounting shell 1; one end of the fuse is tightly connected with the circuit of the heater body 2, responsible for stably transmitting the electric energy from the external power source to the heater body 2 to drive it to work normally; the other end is connected with the external power source through a dedicated wire, ensuring the integrity and continuity of the electric energy transmission; in order to further enhance the protection effect of the fuse, a sturdy protective shell is installed outside the fuse, which not only provides additional physical protection for the fuse to prevent it from being damaged by external force or environmental factors, but also isolates external heat to some extent, ensuring that the fuse can work in a more stable and safe environment.

[0052] The electric control board 13 is used to control the working temperature of the heater body 2; when the ambient temperature or the working temperature of the heater body 2 is lower than the set value, the electric control board 13 sends a heating instruction to the heater body 2 to start or increase the heating power to increase the temperature; on the contrary, when the temperature reaches or exceeds the set value, the electric control board 13 sends an instruction to the heater body 2 to reduce the heating power or stop heating to keep the temperature within the set range; this intelligent control method not only improves the heating efficiency and safety of the heater, but also provides users with a more comfortable and convenient use experience.
