The heater 100 is an electrical appliance for adjusting temperature, which is commonly used for indoor heating to improve the comfort of living and working environments. Due to the portability of the heater 100, it is also suitable for special occasions, such as outdoor activities, temporary places, etc., to provide comfort and convenience for users.

[0028] See also Figure 2 and Figure 3 In one embodiment provided in the present application, the heater 100 includes a housing 10, a mounting bracket 20, a heating module 30, a fan assembly 40 and a mainboard 50. The housing 10 has a housing 11, the mounting bracket 20 is arranged in the housing 11, and the mounting bracket 20 includes a first mounting bracket 21 and a second mounting bracket 22. The heating module 30 is mounted on the first mounting bracket 21, and the fan assembly 40 is connected to the first mounting bracket 21 and is arranged relative to the heating module 30. The mainboard 50 is mounted on the second mounting bracket 22. Specifically, the first mounting bracket 21 is used to install the heating module 30 and the fan assembly 40, that is, only one mounting bracket 20 is required to simultaneously install the heating module 30 and the fan assembly 40, which can reduce the number of parts and components, simplify the installation steps, and simplify the complexity of wiring. The second mounting bracket 22 is arranged at intervals from the first mounting bracket 21, and the second mounting bracket 22 is used to install the mainboard 50, so that the mainboard 50 is arranged at intervals from the heating module 30 and the fan assembly 40. On the one hand, it is easy to install and convenient to maintain and manage; on the other hand, the structural layout of the heater 100 is more compact, which can enhance the heat exchange effect.

[0029] Next, each component of the heater 100 and the specific structure of each component will be introduced one by one.

[0030] See also Figure 4 In this embodiment, the housing 10 is used to install and protect components. At the same time, the housing 10 is also used to support the use place of the heater 100, for example, the ground, a desktop or other supporting platforms. In this embodiment, the housing 10 includes a housing body 12, and the housing body 12 is surrounded by a roughly rectangular frame. The housing 10 also has a accommodating cavity 11, and the accommodating cavity 11 is used to install and place the installed components. The installed components may be a heating module 30, a fan assembly 40, a heat dissipation assembly, and the like. The material of the housing 10 may include a high temperature resistant, flame retardant plastic material, a resin material or a metal material, which can protect the internal components from external damage, and also prevent the user from touching the high temperature components and causing burns.

[0031] As an example, the material of the housing 10 may include ABS plastic, PC plastic or other hard plastic, which can not only reduce the weight of the heater 100 to achieve lightweight, but also make the shell have a certain stability, thereby effectively protecting the components inside the housing 10. On the other hand, the plastic material can withstand moisture and high temperature, and also has good tolerance to possible cleaning agents or disinfectants, which can increase the service life of the heater 100. It should be noted that the material of the housing 10 can also be ceramic material or other materials, which is not limited in this embodiment.

[0032] In some embodiments, the interior of the box 10 may be filled with sound insulation material (not shown in the figure), which may be foam or rubber, etc., so as to reduce the noise generated by the operation of the heater 100 and protect the internal components from impact during transportation and use. In other embodiments, the heater 100 may also include a tipping switch (not shown in the figure), which automatically closes when the heater 100 tips over, thereby preventing the occurrence of fire or further damage and improving the safety of the heater 100.

[0033] See also Figure 2 and Figure 3In this embodiment, the mounting bracket 20 is arranged in the accommodating cavity 11, and the mounting bracket 20 is responsible for fixing and supporting various internal components to ensure the stability and safety of the components during operation. Specifically, the mounting bracket 20 includes a first mounting bracket 21 and a second mounting bracket 22, and the first mounting bracket 21 and the second mounting bracket 22 are arranged at intervals. The first mounting bracket 21 is used to install the heating module 30 and the fan assembly 40, and the second mounting bracket 22 is used to install the mainboard 50, so that the mainboard 50 is spaced apart from the heating module 30 and the fan assembly 40. On the one hand, it is easy to install and maintain and manage. On the other hand, the structural layout of the heater 100 is more compact, which can enhance the heat exchange effect. The material of the mounting bracket 20 may include a high temperature resistant and high strength material, such as a plastic material, a metal material, a glass material, etc., and this embodiment does not impose specific restrictions on this.

[0034] In some embodiments, the mounting bracket 20 further includes a spacing bracket 23, and the spacing bracket 23 is arranged between the first mounting bracket 21 and the second mounting bracket 22, and the mainboard 50 is located on the side of the second mounting bracket 22 away from the spacing bracket 23. The spacing bracket 23 can be used to install wires or electrical connectors or other electronic devices, so that the structural layout of the heater 100 is reasonable. In addition, the spacing bracket 23 is also used to space the first mounting bracket 21 and the second mounting bracket 22, so that the installation of the electronic devices on the first mounting bracket 21 and the electronic devices on the second mounting bracket 22 do not affect each other. In addition, the spacing bracket 23 is also used to play a certain heat insulation role, avoiding contact between electronic devices and isolating heat conduction. As an installation example, when the heater 100 is normally placed on the use platform, the first mounting bracket 21, the spacing bracket 23 and the second mounting bracket 22 are stacked. The first mounting bracket 21 and the second mounting bracket 22 are respectively located on the upper and lower sides of the spacing bracket 23 along the direction of gravity, and the second mounting bracket 22 is located at the bottom in the direction of gravity. At this time, the main board 50 is located below the heating module 30 and the fan assembly 40. On the one hand, it can further improve the layout rationality of the heater 100 and improve the compactness of the structure; on the other hand, it can prevent the main board 50 from being affected by the temperature rise of the upward hot air and be in a lower temperature area, which is beneficial to improve the service life of the main board 50.

[0035] Specifically, the first mounting bracket 21 includes a main frame 211, and the main frame 211 surrounds to form an installation space 212. The heating module 30 is detachably arranged in the installation space 212, and is used to convert electrical energy into thermal energy to provide the required heating heat. The heating module 30 may include a heating element 32, and the heating element 32 is used to heat the air. The heating element 32 may be an electric heating wire heating element 32, a ceramic heating element 32, a metal electric heating tube, a PTC heating element 32, etc., and this embodiment is not limited to this. As an example, the heating element 32 is a PTC heating element 32, and the PTC heating element 32 has the characteristics of low thermal resistance and high heat exchange efficiency, can quickly generate heat in a short time, and can improve the working efficiency of the heater 100. In this embodiment, the heating module 30 also includes a terminal plug 31, and the terminal plug 31 is used to connect the heating element 32 to the mainboard 50, the power supply or other electronic devices. Specifically, a connection groove 2111 is provided on one side of the main frame 211 facing the second mounting bracket 22, and the connection groove 2111 penetrates the spacing bracket 23. The terminal plug 31 penetrates the connection groove 2111 and is installed in the spacing bracket 23. On the one hand, the structure of the heater 100 can be compact and the layout can be reasonable; on the other hand, the connection wires between the heating module 30 and the mainboard 50, the power supply or other electronic devices can be simplified, and the connection wires can be made as short as possible to improve the efficiency and reliability of the connection. In addition, the shorter connection wires are also convenient for wiring and maintenance, making the assembly and troubleshooting of the heater 100 more convenient.

[0036] The main frame 211 is also used to install and fix the fan assembly 40, which is detachably fixed to the main frame 211 by screws and part of the fan assembly 40 is embedded in the installation space 212, and the fan assembly 40 and the heating module 30 are arranged in sequence. The fan assembly 40 is used to inhale cold air and transport the hot air heated by the heating module 30 to the required space to achieve the heating effect. Specifically, the box 10 also has a first opening 13, which is located at one end of the box body 12 and connected to the accommodating cavity 11, so that the user can install parts from the first opening 13 and perform maintenance management on the parts. The box 10 also includes a first cover plate 15, which is used to cover the first opening 13 and protect the electronic devices inside the accommodating cavity. In this embodiment, the first cover plate 15 is provided with an air inlet 151, which is connected to the outside of the accommodating cavity 11, and the air inlet 151 is arranged toward the fan assembly 40. When the fan assembly 40 is working, external cold air is sucked into the accommodating cavity 11 through the air inlet 151, and the heating module 30 heats the sucked cold air to form hot air.

[0037] In this embodiment, the box body 10 also has a second opening 14, and the second opening 14 and the first opening 13 are respectively located on both sides of the box body 12, and the second opening 14 and the first opening 13 are arranged at intervals, so that the user can install parts from the second opening 14 and perform maintenance and management on the parts. The box body 10 also includes a second cover plate 16 that is opposite to the first cover plate 15, and the second cover plate 16 covers the second opening 14 and protects the electronic components inside the accommodating cavity 11. The first cover plate 15, the second cover plate 16 and the box body 12 form a closed space to protect the electronic components inside the box body 10. In this embodiment, the second cover plate 16 is also provided with an air outlet area 161, and the air outlet area 161 connects the accommodating cavity and the outside world, and the fan assembly 40 blows the hot air formed by the heating module from the air outlet area 161 to the outside world.

[0038] In other embodiments, in order to make the structure layout of the heater 100 compact, the spacing between the first cover plate 15, the fan assembly 40, the heating module 30 and the second cover plate 16 is small, which helps to improve the efficiency of heat transfer and reduce heat loss, so that the heating effect is more rapid and direct. Secondly, the smaller spacing can reduce the loss of heat energy, and can provide the same heating output at a lower energy consumption, which helps to save energy and reduce electricity expenses. At the same time, it also helps to reduce the volume of the heater 100, making it more lightweight and easy to carry.

[0039] See also Figure 2 and Figure 5 In this embodiment, the mainboard 50 is mounted on the second mounting bracket 22. The mainboard 50 serves as a control platform, which is used to electrically connect the heating module 30 and the fan assembly 40, and controls the basic operation of the heater 100. It also has functions such as circuit conduction and fault diagnosis. Specifically, the mainboard 50 includes a board body 51, and the board body 51 is roughly in the shape of a long plate. The mainboard 50 can be a hard circuit board or a dielectric substrate, and this embodiment does not impose specific restrictions on this. As an example, the mainboard 50 can be a dielectric substrate, which plays a supporting and insulating role. The dielectric substrate has good electrical insulation performance and chemical stability, which not only ensures the structural stability of the mainboard 50, but also is used to improve the performance and reliability of the circuit. In this embodiment, the board body 51 has a first surface 511 and a second surface 512, the first surface 511 and the second surface 512 are opposite to each other, and the first surface 511 faces and is connected to the second mounting bracket 22. Specifically, the first surface 511 may be provided with a connector (not shown in the figure), which is fixedly connected to the second mounting bracket 22 through the connector. The connector may be a bolt and nut matching structure, or a connecting slot and a connecting boss matching structure, which is not specifically limited in this embodiment. In this embodiment, the mainboard 50 can carry a variety of electronic devices and different modules to achieve diversified functions and enhance user experience.

[0040] As an example, the mainboard 50 includes a power module 5121 and a control module 5122, and the power module 5121 and the control module 5122 are arranged on the second surface 512. By arranging the power module 5121 and the control module 5122 on the second surface 512, it is unnecessary to occupy the installation space of the second mounting bracket 22, thereby improving the convenience of installation. At the same time, it is possible to avoid the power module 5121 and the control module 5122 from directly contacting the heat generated by the operation of the fan assembly 40, the heating module 20 and other components, so that the power module 5121 and the control module 5122 are in a relatively low temperature area, which is conducive to improving the service life of the mainboard 50.

[0041] The power module 5121 is used to convert the input power into a stable voltage and current suitable for the mainboard 50 and the various electronic devices connected thereto, so as to achieve conduction between the various circuits and devices, thereby ensuring the stable operation and performance of the heater 100. The power module 5121 may also have a protection function to prevent damage caused by power anomalies, while also protecting the safety of the user.

[0042] The control module 5122 is used to control the operating parameters of the heater 100, such as adjusting the speed of the fan, the power of the heating module 30 and other related parameters according to the user input interface and the feedback of other external signals, to ensure that the heater 100 can provide a constant and comfortable indoor temperature under various environmental conditions. The control module is also used to allow the heater 100 to be connected to a smart home system or a user's mobile device to achieve remote control and intelligent interaction, and provide users with a comfortable and reliable heating solution. It should be noted that the control module 5122 is not only limited to the functions mentioned above, but also has other control functions of conventional heaters 100.

[0043] As another example, the mainboard 50 may also include an electronic device 5123, which is arranged on the second surface 512. The number of the electronic device 5123 may be multiple or one, and different functions are realized according to the type of the electronic device 5123 carried. The electronic device 5123 may be at least one of a capacitor, a resistor, an inductor, a control chip, an electrical connection terminal or other electronic devices. As an example, the electronic device 5123 may be an electrical connection terminal, which is used to provide a line connection point, so that the connection between the circuits is simpler and more reliable. At the same time, it is also convenient for disassembly work when repairing and replacing parts. In the present embodiment, the above-mentioned electronic devices, power modules and control modules are all arranged on the second surface 512 of the mainboard 50, and the second surface 512 has a larger installation space 212, which is convenient for the maintenance and management of the device.

[0044] See also Figure 4 and Figure 5In order to further control the output temperature of the heater 100 within the temperature range required by the user, the heater 100 may also include a temperature sensing device 52. The temperature sensing device 52 is disposed at an end of the mainboard 50 relatively away from the heating module 30, and protrudes toward the fan assembly 40. As an example, the temperature sensing device 52 may be disposed between the fan assembly 40 and the first cover body 15. The temperature sensing device 52 is used to detect and monitor the temperature changes of the heater 100 during the heating process in real time, specifically to detect the temperature changes of the environment around the fan assembly 40, and to regulate the output power of the fan assembly 40 according to the temperature changes. The temperature sensing device 52 may be a thermocouple, a thermistor, an infrared sensor, etc., which is not limited in this embodiment.

[0045] In order to improve the air circulation around the temperature sensing device 52, a vent 152 is further provided on the side of the first cover plate 15 close to the temperature sensing device 52. The vent 152 and the air inlet 151 are arranged at intervals and the vent 152 is arranged opposite to the temperature sensing device 52. The vent 152 connects the accommodating cavity 11 and the outside to supply air to the temperature sensing device 52. It should be noted that the number of the temperature sensing device 52 can be multiple, and the temperature sensing device 52 can also be arranged at one end of the mainboard 50 close to the heating module 30 and protrude toward the air outlet area 161. The corresponding vent 152 can be arranged on the side of the second cover plate 16 close to the temperature sensing device 52. At this time, the temperature sensing device 52 can be in contact with the actual air temperature of the air outlet area 161 of the heater 100, and adjust or maintain it within the temperature range required by the user according to the actual air temperature to improve the user's experience.

[0046] In order to further improve the use requirements of the heater 100, in this embodiment, the heater 100 may also include a light source 53. The light source 53 is arranged on a side of the mainboard 50 relatively close to the second cover plate 16, and the light source 53 is used to provide lighting or form decorative light or information prompt light. Specifically, the light source 53 is detachably connected to the mainboard 50, which is convenient for the maintenance and replacement of the light source 53. The box body 12 is also provided with a light outlet 17, and the light outlet 17 is located on the light path formed by the light source 53, so that the light generated by the light source 53 is emitted to the outside through the light outlet 17. In this embodiment, the light source 53 can be a halogen light bulb, UHP (ultra-high pressure mercury bulb), UHE (ultra-high pressure mercury bulb) and other high-pressure gas light sources 53 or LED light sources, etc., and this embodiment does not limit this. As an example, the light source 53 is an LED light source, which can be a monochrome LED lamp bead or a tricolor LED lamp bead. On the one hand, it can improve the efficiency of converting electrical energy into light energy, thereby reducing energy waste. At the same time, LED light sources generate less heat when lighting, which plays a role in energy saving and environmental protection. On the other hand, LED light sources have a long service life, which reduces the frequency of light source replacement and thus reduces the cost of use. At the same time, LED can avoid damage to human eyes and improve safety of use.

[0047] In other embodiments, the number of the light sources 53 and the light outlet holes 17 can be multiple. In order to improve the independence between each light source and improve the overall effect of lighting or decorative light, the heater 100 can also include shading ribs 55. Specifically, multiple light sources 53 are arranged on the main board 50 at intervals, multiple light outlet holes 17 are arranged one by one on the light path formed by the corresponding light sources 53, and the shading ribs 55 are arranged between two adjacent light sources 53. The shading ribs 55 can be made of opaque or translucent materials, such as plastic, rubber or specially treated paper. The shading ribs 55 form a physical barrier that can block direct sight and ensure that the light of each light source 53 is limited to its predetermined lighting area, thereby avoiding light mixing and interference between different light sources 53.

[0048] In this embodiment, the heater 100 further includes a button 18 and an elastic member 54, the elastic member 54 is against the button 18, and the heater 100 can be controlled by pressing the button 18. As an example, the button 18 can be a touch button. Specifically, the outline and function logo of the touch button are etched on the box body 12 by laser engraving or silk screen printing technology, which can not only provide a clear visual effect, but also enhance the user's experience through touch feedback. The elastic member 54 is arranged on the main board 50 and protrudes toward the box body 12, and the elastic member 54 elastically abuts against the touch button 18. The touch button 18 can control various functions of the heater 100, such as turning on and off, adjusting the temperature, setting the timer, changing the wind speed, selecting the working mode, etc., which is not limited in this embodiment. The elastic member 54 can be a spring or an elastic sleeve, a spring or other elastic device, which is not limited in this embodiment. In order to improve the movement accuracy of the elastic member 54, a limiting hole 19 is further provided on the side of the box body 12 away from the touch button 18. The elastic member 54 is passed through the limiting hole 19 and abuts against the touch button 18, which can prevent the elastic member 54 from tilting and deviating from the movement trajectory during movement.

[0049] In this embodiment, since the elastic member 54 is disposed on the main board 50 and elastically abuts against the touch button 18 of the box body 12, in order to improve the stability of the elastic movement of the elastic member 54, a plurality of main board limiting ribs 121 are further disposed on the side of the box body 12 facing the main board 50. Specifically, the main board 50 is clamped and fixed between the main board limiting ribs 121, which can improve the stability of the elastic movement of the elastic member 54 on the one hand, and improve the installation stability of the main board 50 on the other hand, and reduce the risk of the main board 50 falling off.

[0050] In summary, the embodiment of the present application provides a heater 100, which includes a housing 10, a mounting bracket 20, a heating module 30, a fan assembly 40 and a mainboard 50.
