Description

Technical Field

[0001] This application relates to the field of heating equipment technology, and more particularly to a heater. Background Technology

[0002] A temperature limiter is a safety protection device used to prevent equipment from overheating. It is widely used in the temperature limit protection of electric heating appliances. The temperature limiter can sense the temperature of the electric heating appliance. When it senses that the temperature of the electric heating appliance is higher than the limit temperature, it will automatically cut off the circuit to achieve temperature control and prevent the equipment from overheating and causing danger.

[0003] In related technologies, the thermostat in a heater is in direct contact with hot air. The heat from the heating element must first be transferred to the air and then to the thermostat. Because air has a low thermal conductivity, the thermostat takes a long time to sense the temperature change of the heating element, resulting in an excessively long time for the thermostat to cut off power, which affects the reliability and safety of the heater.

[0056] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0057] Please see Figure 1 and Figure 2 This application provides a heater 100, which has a first state and a second state. Specifically, the heater 100 includes a main unit 1 and a support structure.

[0058] The main unit 1, as the main body of the heater 100, is capable of generating heat and radiating it to the usage environment to provide warmth to the environment and the user. The main unit 1 includes a casing 11, the shape of which can be, but is not limited to, a cube, cuboid, cylinder, or frustum. This application does not impose specific limitations on the shape of the casing 11. The material of the casing 11 can be, but is not limited to, at least one of metal and high-strength plastic, giving the casing 11 good mechanical strength and corrosion resistance. It is understood that, as... Figure 3 As shown, the main unit 1 also includes internal components such as a heating element 2 and a controller (not shown in the figure). The casing 11 isolates the internal components of the heater 100 from the outside world, thus preventing users from directly contacting the internal components of the main unit 1 and reducing the occurrence of safety accidents such as burns and electric shocks. The casing 11 also provides protection for the internal components of the heater 100, preventing dust, moisture, oil, and other external impurities from entering and protecting the internal components from the influence of the external environment.

[0059] In this embodiment, the housing 11 is described as a cuboid, which has a length direction, i.e., the length direction of the main unit 1. The housing 11 has a first end 11a and a second end 11b disposed opposite to each other in the length direction, i.e., the main unit 1 has a first end 11a and a second end 11b disposed opposite to each other in the length direction. In this embodiment, the housing 11 also has a mounting cavity 111, and the aforementioned internal components are disposed within the mounting cavity 111.

[0060] Furthermore, the housing 11 is also provided with a heat radiation port 113 communicating with the mounting cavity 111. During operation, the heat generated by the heating element 2 can be radiated to the outside of the heater 100 through the heat radiation port 113 to increase the temperature outside the heater 100. In one embodiment, the housing 11 can also be provided with an air inlet 112, and the main unit 1 also includes a blower 8 located in the mounting cavity 111. Thus, during operation, the blower 8 drives the outside airflow into the housing 11 and exchanges heat with the heating element 2, and blows warm air out through the heat radiation port 113, thereby expanding the range of heat radiation. This can better change the temperature of the area outside the heater 100. For example, when the heater 100 is placed in a user's room, the warm airflow can fill the entire room relatively evenly, making the temperature of the entire room rise relatively evenly.

[0061] The heating element 2 is housed in the mounting cavity 111 and located between the air inlet 112 and the heat radiation port 113 of the housing 11. The heating element 2 can be located on either the air outlet or air inlet path of the blower 8. Thus, after the heating element 2 generates heat, it is radiated to the user environment through the heat radiation port 113 to provide heating to the user and the user. The housing 11 has a first end 11a and a second end 11b arranged opposite each other along its length; that is, the heating element 2 also has a first end 11a and a second end 11b arranged opposite each other along its length. The heating element 2 can be arranged within the mounting cavity 111 along its length. The heating element 2 can be, but is not limited to, a carbon fiber heating element, a halogen heating element, a quartz tube heating element, a metal tube heating element, or an electric heating wire heating element. In this embodiment, the specific form of the heating element 2 is not limited.

[0062] It is understandable that the air inlet 112 and heat radiation outlet 113 can be elongated, or circular, elliptical, irregular, or other shapes. Furthermore, the air inlet 112 and heat radiation outlet 113 can be located on opposite sides of the housing 11, for example, Figure 1 and Figure 2 As exemplarily shown, when the housing 11 is a cuboid, the air inlet 112 and the heat radiation outlet 113 are respectively arranged on the parallel sides of the cuboid. Of course, the air inlet 112 and the heat radiation outlet 113 can also be arranged on two adjacent sides of the housing 11.

[0063] In addition, a first grille (not shown in the figure) is provided on the housing 11 at the position corresponding to the air inlet 112. The first grille can block some foreign objects from entering the mounting cavity 111 and affecting the electronic components. A second grille (not shown in the figure) can also be provided on the housing 11 at the position corresponding to the heat radiation port 113. The second grille prevents the user's hand from entering the mounting cavity 111 through the heat radiation port 113, reducing the occurrence of safety accidents such as burns and improving the safety of the heater 100. The first grille can be mesh, honeycomb, or an array of holes, and / or the second grille can be mesh, honeycomb, or an array of holes. This application does not impose specific limitations on this.

[0064] The support structure serves as the main support for the heater 100, supporting the main unit 1 and enabling the heater 100 to have a first state and a second state. Specifically, the main unit 1 has a first surface and a second surface, wherein the first surface is the surface of the main unit 1 along its width direction, and the second surface is the surface of the main unit 1 along its length direction, with the first surface perpendicular to the second surface. In one configuration, the support structure includes a base, which can be connected to the first surface and support the main unit 1 to enable the main unit 1 to have the first state; the base can also be connected to the second surface and support the main unit 1 to enable the main unit 1 to have the second state. Alternatively, in another configuration, the support structure can be both the first and second surfaces of the main unit 1, i.e., the first surface is directly placed on the support surface to enable the main unit 1 to have the first state; and the second surface is directly placed on the support surface to enable the main unit 1 to have the second state. It is understood that the support structure can have various different forms, and this application does not impose any specific limitations on them.

[0065] In some embodiments, such as Figures 1 to 4 As shown, the support structure includes a first support base 6 and a second support base 7. The first support base 6 is connected to the first end 11a, and the second support base 7 is detachably mounted on the second end 11b or the first support base 6. It can be understood that the first support base 6 and the second support base 7 serve as the main support structure of the heater 100 to support the main unit 1.

[0066] Specifically, when the heater 100 is in the first state, the second support base 7 is detachably connected to the second end 11b. The second support base 7 and the first support base 6 cooperate to support the main unit 1 on the support surface, and the side of the housing 11 with the air inlet 112 faces the support surface. When the heater 100 is in the second state, the second support base 7 is detached from the second end 11b and detachably connected to the first support base 6. The second support base 7 and the first support base 6 together support the main unit 1 on the support surface at the first end 11a, and the end face of the housing 11 with the first end 11a faces the support surface.

[0067] This application connects the second support 7 to the second end 11b or the first support 6 respectively, so that the heater 100 has a first state and a second state. This provides multiple ways to place the heater 100, allowing users to choose the appropriate usage state according to the actual scenario. Users can choose the air outlet direction of the heater 100 to be horizontal or vertical, so as to more considerately meet the user's urgent need for warmth.

[0068] It should be noted that when the first state can be either a vertical placement state or a horizontal placement state, the second state can be either a vertical placement state or a horizontal placement state. In this embodiment of the application, for ease of explanation, the first state of the heater 100 is a horizontal placement state, that is, the heater 100 is placed horizontally, and the second state of the heater 100 is a vertical placement state, that is, the heater 100 is placed upright. The supporting surface can be the ground, a table, or other flat surfaces in the indoor space used for placing the heater 100.

[0069] It should also be noted that when the heater 100 is in the first state, the heat radiation outlet 113 faces upward, meaning that the heat radiation outlet 113 is in a state of upward airflow relative to the user, that is, the heat radiation outlet 113 blows air upward towards the user. When the heat radiation outlet 113 faces upward, it can be parallel to the horizontal plane or at an angle to the horizontal plane. When the heater 100 is in the second state, the heat radiation outlet 113 faces forward, meaning that the heat radiation outlet 113 is in a state of forward airflow relative to the user, that is, the heat radiation outlet 113 blows air forward towards the user. When the heat radiation outlet 113 faces forward, it can be parallel to the vertical plane or at an angle to the vertical plane.

[0070] Furthermore, for example, when the housing 11 is rectangular, in the first state, the main unit 1 will be placed horizontally, which helps to reduce the space occupied by the heater 100 in the vertical direction in the usage environment; while in the second state, the main unit 1 will be placed vertically, which helps to reduce the space occupied by the heater 100 in the horizontal direction in the usage environment, thereby enabling the heater 100 of this application embodiment to adapt to more usage environments.

[0071] Please refer to the following: Figures 3 to 5 In this embodiment of the application, the heater 100 also includes a heat-conducting sheet 3 and a temperature limiter 4.

[0072] The heat-conducting plate 3 is housed in the mounting cavity 111 and makes thermal contact with the heating element 2. This allows for direct heat conduction from the heating element 2 via the heat-conducting plate 3, optimizing the heat conduction path and reducing heat loss during the heat conduction process. The heat-conducting plate 3 is made of a material with good thermal conductivity, such as a metal, specifically stainless steel or aluminum alloy. Furthermore, this application does not impose specific limitations on the shape of the heat-conducting plate 3; its shape can include, but is not limited to, rectangles, circles, and triangles.

[0073] The temperature limiter 4 is a safety protection device used to prevent overheating of the equipment. When the temperature of the heater 100 is sensed to be higher than a predetermined temperature, it automatically cuts off the circuit to achieve temperature control. In this embodiment, the temperature limiter 4 is housed in the mounting cavity 111. The temperature limiter 4 has a temperature sensing part 41, which is in thermal contact with the heat-conducting sheet 3 and can directly receive the heat from the heat-conducting sheet 3. Thus, the heat from the heating element 2 can be directly conducted to the temperature sensing part 41 of the temperature limiter 4 through the heat-conducting sheet 3, shortening the heat transfer path. Furthermore, the temperature limiter 4 is connected in series in the working circuit of the heating element 2. Understandably, the temperature limiter 4 also includes a control module. After the temperature sensing part 41 senses the temperature of the heat-conducting sheet 3, it inputs the sensed temperature to the control module. The control module compares the sensed temperature with the predetermined temperature. When it finds that the sensed temperature is higher than the predetermined temperature, it can directly trigger the temperature limiter 4 to disconnect the circuit, thereby cutting off the working circuit of the heating element 2. This setting allows the thermostat 4 to quickly cut off power when it senses that the temperature is too high, making the power-off protection of the heater 100 more timely and effective, and helping to improve the safety of the heater 100.

[0074] Based on the above scheme, by setting a heat-conducting plate 3 in the heater 100, and having the heat-conducting plate 3 in thermal contact with the temperature sensing part 41 of the temperature limiter 4 and the heating element 2 respectively, the heat of the heating element 2 can be directly conducted to the temperature sensing part 41 of the temperature limiter 4 through the heat-conducting plate 3, which significantly shortens the time required for the temperature limiter 4 to sense the temperature, making the power-off protection of the heater 100 more timely and effective, thereby better improving the safety performance of the heater 100.

[0075] In this embodiment of the application, the host 1 also includes a display screen (not shown in the figure) and a sensor (not shown in the figure). The display screen is disposed on the outside of the housing 11, and the sensor can be disposed on the outside of the housing 11 or inside the mounting cavity 111. The heating component 2, the air supply fan 8, the display screen, the sensor, and the temperature limiter 4 are all electrically connected to the controller.

[0076] In some implementations, users can control the operating mode of the heater 100 via an app or remote control. Specifically, the controller has a wireless module for receiving control signals from the app or remote control to control the heater 11. The area of ​​the housing 11 corresponding to the controller or electronic components has a mesh structure, which reduces signal interference and ensures the effectiveness of remote control operations when using the remote control to control the heater 100, regardless of whether the heater 100 is in its first or second state.

[0077] The air supply fan 8 and the heating element 2 are spaced apart within the mounting cavity 111. The air supply fan 8 can be a cross-flow fan, axial flow fan, etc., and this embodiment does not limit this. This arrangement forces the air around the heater 100 to circulate, thereby improving the heat transfer efficiency between the air and the heating element 2 and enhancing the heating effect. Furthermore, the user can adjust the speed of the air supply fan 8 according to actual usage needs, achieving precise temperature control of the heater 100 to the ambient environment, greatly improving the user's flexibility in using the heater. Of course, this application is not limited to this. In other embodiments, the main unit 1 may not include the air supply fan 8, and in the absence of the air supply fan 8, heat exchange between the air and the heating element 2 is achieved through natural convection.

[0078] The display screen can show specific operating parameters of the heater 100, such as fan speed, temperature, and whether it is placed upright or horizontally. When the heater 100 is in a first state, the sensor outputs a first operating signal, and the controller controls the display screen to show a first display interface based on the first operating signal. When the heater 100 is in a second state, the sensor outputs a second operating signal, and the controller controls the display screen to show a second display interface based on the second operating signal.

[0079] For example, when the casing 11 is rectangular, in the first state of the heater 100, the main unit 1 is placed horizontally. Therefore, the text of the parameters displayed on the first display interface is displayed facing the user, and the display interface is adaptively adjusted for easy viewing. In the second state of the heater 100, the main unit 1 is placed vertically. Therefore, the text of the parameters displayed on the second display interface is adaptively displayed facing the user. That is, the display interface is adjusted according to the placement of the heater 100 to facilitate viewing. Therefore, there is no need to turn one's head or other means to view the content displayed on the display interface, thereby effectively improving the user experience.

[0080] The sensor is used to detect the placement status of the heater 100. The sensor includes at least one of the following: tilt switch, temperature sensor, acceleration sensor, gyroscope and angular velocity sensor. This application embodiment does not specifically limit the type of sensor.

[0081] The tilt switch can include mechanical tilt switches and photoelectric tilt switches. For example, a mechanical tilt switch can include a gravity ball and a trigger switch. If the heater 100 changes state, the gravity ball will trigger the trigger switch under the action of gravity to generate a signal and output it to the controller.

[0082] The temperature sensor may include at least three temperature probes, which are arranged in different positions. For example, one probe may be placed at the air inlet 112, and the other two may be placed at intervals at the air inlet 112. By utilizing the principle that hot air will automatically rise, that is, the temperature of the position higher than the position lower, the heater 100 can be determined by the temperature data difference detected in real time by the three temperature probes. It can be determined whether the heater 100 has changed state or is not in the first state and the second state at the same time. If it is determined that the state has changed or is not in the first state and the second state at the same time, a signal will be generated and output to the controller.

[0083] The accelerometer can detect whether the acceleration of the host 1 changes significantly to determine whether the heater 100 has switched states or is not in the first state or the second state at the same time. If it is determined that the state has switched or is not in the first state or the second state at the same time, a signal will be generated and output to the controller.

[0084] The gyroscope can use the high-speed rotating gyroscope to measure the angular velocity and angular acceleration of the host 1, thereby determining whether the heater 100 has changed state, or whether it is not in the first state or the second state at the same time. If it is determined that the state has changed or that it is not in the first state or the second state at the same time, a signal will be generated and output to the controller.

[0085] The angular velocity sensor can directly measure the tilt angle of the main unit 1 to determine whether the heater 100 has switched states or is not in both the first and second states at the same time. If the tilt angle of the main unit 1 exceeds the preset angle range of the angular velocity sensor, the angular velocity sensor will determine that it has switched states or is not in both the first and second states at the same time, and will generate a signal and output it to the controller.

[0086] The controller is electrically connected to the sensor, heating element 2, and air blower 8, and is used to control at least one of the air blower 8 and heating element 2 to execute a corresponding operating mode based on the signal output by the sensor. Thus, by detecting through the sensor, the controller can determine whether the heater 100 has changed state, and if it determines that the heater 100 has changed state, the controller can further control the air blower 8 and heating element 2 to execute the corresponding operating mode, thereby effectively improving the intelligence level of the heater 100.

[0087] In some embodiments, the sensor outputs a first operating signal when the heater 100 is in a first state, and the controller controls the air blower 8 to execute a first operating mode according to the first operating signal. When the heater 100 is in a second state, the sensor outputs a second operating signal, and the controller controls the air blower 8 to execute a second operating mode according to the second operating signal.

[0088] Understandably, when the heater 100 is in its first state, the heat radiation outlet 113 faces vertically upwards, meaning the hot air can be blown towards higher areas of the environment, allowing for better circulation. To achieve rapid heating of the environment, this embodiment increases the rotation speed of the blower 8, controlling it to operate in the first working mode, enabling the environment to be heated quickly and allowing users to experience warmth and comfort rapidly.

[0089] When the heater 100 is in the second state, the heat radiation port 113 is horizontal, meaning the hot air can be blown directly onto the user's body for better warmth. To cater to the user's physical needs, this embodiment can reduce the speed of the blower fan 8, i.e., control the blower fan 8 to execute the second working mode, so that the heater 100 blows out a gentler hot air through the lower speed of the blower fan 8.

[0090] Please refer to the following: Figure 3 , Figure 4 and Figure 6The housing 11 includes an outer shell 114 and a support assembly 115. The outer shell 114 is the external structure of the housing 11, and has a first end 11a and a second end 11b, and a mounting cavity 111. The support assembly 115 is disposed in the mounting cavity 111 and separates the mounting cavity 111 into a heating cavity 111a and an electrical cavity 111b. The air inlet 112 and the heat radiation outlet 113 on the outer shell 114 are both connected to the heating cavity 111a. In this embodiment, the heating element 2 is disposed in the heating cavity 111a, and the heat-conducting plate 3 is also located in the heating cavity 111a. The temperature limiter 4 is mounted on the support assembly 115, which has a through hole through which the temperature sensing part 41 of the temperature limiter 4 can extend into the heating cavity 111a to make thermal contact with the heat-conducting plate 3.

[0091] It is understood that in this embodiment, the heating element 2 and the air blower 8 are both located in the heating chamber 111a, while the display screen, sensor, temperature limiter 4, and controller are all located in the electrical chamber 111b. This chamber design facilitates wiring and reduces heat transfer from the heating element 2 to the electrical chamber 111b, preventing the electronic components and electrical connections in the electrical chamber 111b from being affected by high temperatures, thus improving the reliability and safety of the heater 100.

[0092] Please refer to the following: Figure 3 and Figure 6 In some embodiments, the electrical cavity 111b includes a motor cavity 111b1 and a main control cavity 111b2. The bracket assembly 115 includes a first bracket assembly 1151 and a second bracket assembly 1154. The first bracket assembly 1151 is located at the first end 11a and connected to the housing 114, and the second bracket assembly 1154 is located at the second end 11b and connected to the housing 114. Understandably, the first bracket assembly 1151 and the second bracket assembly 1154 divide the mounting cavity 111 into three parts: the motor cavity 111b1 located at the first end 11a, the main control cavity 111b2 located at the second end 11b, and the heating cavity 111a located between the motor cavity 111b1 and the main control cavity 111b2. Furthermore, the first bracket assembly 1151 is connected to the first end 11a of the heating component 2, and the second bracket assembly 1154 is connected to the second end 11b of the heating component 2. Thus, the heating component 2 can be fixedly installed in the heating chamber 111a through the first bracket assembly 1151 and the second bracket assembly 1154.

[0093] In addition, the electronic components in the motor cavity 111b1, main control cavity 111b2, and heating cavity 111a are functionally independent and electrically connected, allowing the electronic components in the three cavities to both cooperate and perform their respective functions. This compartmentalized design makes the internal functions of the heater 100 clearer, facilitating management and maintenance. When maintenance or repair is required on a component within a module, the problem can be located more quickly, reducing the impact on other electronic component modules and improving maintenance efficiency.

[0094] Continue reading Figure 3 In some embodiments, the first support assembly 1151 includes a first mounting bracket 1152 and a first mounting pressure plate 1153. The first mounting bracket 1152 is connected to the outer casing 114, and the first mounting bracket 1152 and the first mounting pressure plate 1153 are located on opposite sides of the heating element 2. The first mounting bracket 1152 and the first mounting pressure plate 1153 are fixedly connected to each other to place the heating element 2 between them, thereby fixing the heating element 2. The first mounting bracket 1152 and the first mounting pressure plate 1153 can be connected by screws, snap-fit ​​connections, or other methods; this application does not impose specific limitations on this.

[0095] Similarly, the second bracket assembly 1154 includes a second mounting bracket 1155 and a second mounting plate 1156. The second mounting bracket 1155 is connected to the housing 114, and the second mounting bracket 1155 and the second mounting plate 1156 are located on opposite sides of the heating element 2. The second mounting bracket 1155 and the second mounting plate 1156 are fixedly connected to each other to place the heating element 2 between them, thereby fixing the heating element 2. The second mounting bracket 1155 and the second mounting plate 1156 can be connected by screws, snap-fit ​​connections, or other methods; this application does not impose specific limitations on this.

[0096] Please see Figure 3 In some embodiments, the housing 11 further includes an air duct plate 118, which is disposed on both sides of the heating element 2 in the thickness direction. The air duct plate 118 is connected to the outer casing 114. The air duct plate 118 is used to fill the gap between the heating element 2 and the housing 11, preventing the gap between the heating element 2 and the outer casing 114 from being too large, which would cause the heating element 2 to shake, and thus helping to improve the stability of the heating element 2.

[0097] Please see Figure 3In some embodiments, the support assembly 115 further includes a fan support 1157, which is disposed within the heating chamber 111a and located on one side of the air inlet 112. Both ends of the fan support 1157 are connected to the first mounting bracket 1152 and the second mounting bracket 1155, respectively. The fan support 1157 can be connected to the first mounting bracket 1152 and the second mounting bracket 1155 using snap-fit ​​or screw-fit methods; this application does not impose specific limitations on this. Furthermore, a supply fan 8 is disposed on the fan support 1157, thereby being located within the heating chamber 111a. The supply fan 8 can be connected to the fan support 1157 using snap-fit ​​or screw-fit methods; this application also does not impose specific limitations on this.

[0098] Please see Figure 3 In some embodiments, the housing 11 further includes a first connecting frame 116 and a second connecting frame 117. The first connecting frame 116 is connected to the outer casing 114 and located on the side of the air inlet 112. The first connecting frame 116 is used to install the first grille. The first connecting frame 116 and the first grille can be connected by snap-fit, magnetic connection, or other methods; this application does not impose specific limitations on this. Furthermore, a detachable connection facilitates cleaning and replacement of the first grille. The second connecting frame 117 is connected to the outer casing 114 and located on the side of the heat radiation port 113. The second connecting frame 117 is used to install the second grille. The second connecting frame 117 and the second grille can be connected by snap-fit, magnetic connection, or other methods; this application does not impose specific limitations on this. Furthermore, a detachable connection facilitates cleaning and replacement of the second grille.

[0099] Please continue reading. Figure 3 The first clearance hole 114a includes a hole body 114a1 and clearance portions 114a2 disposed on both sides of the hole body 114a1 and communicating with the hole body 114a1. Since the first bracket assembly 1151 and the second bracket assembly 1154 are inserted into and disposed within the mounting cavity 111 through the air inlet 112 or the heat radiation outlet 113, this arrangement allows for slight elastic deformation of the housing 114 during installation of the first bracket assembly 1151 and the second bracket assembly 1154, facilitating smoother insertion and assembly. Simultaneously, this arrangement allows the housing 114 to be designed as a single-piece structure (e.g., Figure 3As shown, this design avoids defects such as poor stability caused by the assembly of multiple panels into the outer casing 114, and also facilitates the processing and manufacturing of the outer casing 114, simplifying the installation process. Understandably, the casing 11 also includes a decorative panel 117, which is snapped onto the clearance portion 114a2 and connected to the opposite sides of the outer casing 114 relative to the clearance portion 114a2. Thus, the decorative panel 117 connects the outer casing 114 to form a closed frame, which helps improve the stability of the outer casing 114, and secures the bracket assembly 115 within the mounting cavity 111, preventing the bracket assembly 115 from shaking within the mounting cavity 111. The decorative panel 117 can also be used to cover the clearance portion 114a2, which helps improve the neatness of the appearance of the casing 11, thereby enhancing the overall aesthetics of the heater 100.

[0100] Please see Figure 6 and Figure 7 In some embodiments, the first support base 6 includes a first support body 61 and a first shaft 62, which are connected together. The first support body 61 serves as the main support of the first support base 6, supporting the host 1, while the first shaft 62 serves as the connecting body of the first support base 6, connecting the host 1. The first bracket assembly 1151 is provided with a first shaft hole 11c, and the outer shell 114 is provided with a first clearance hole 114a corresponding to the first shaft hole 11c. The first shaft 62 is inserted into the first shaft hole 11c through the first clearance hole 114a to position the first support base 6 at the first end 11a. The first shaft 62 can be locked to the first bracket assembly 1151 by a screw connector to position the first support base 6 at the first end 11a.

[0101] Please see Figure 7 In some embodiments, the second support base 7 includes a second support body 71 and a second shaft 72, with the second support body 71 connected to the second shaft 72. The second support body 71 serves as the supporting body of the second support base 7, supporting the host 1, while the second shaft 72 serves as the connecting body of the second support base 7, connecting the host 1. A second shaft hole 11d is provided in the second bracket assembly 1154, and a second clearance hole 114b is provided in the outer shell 114 corresponding to the second shaft hole 11d. The second shaft 72 passes through the second clearance hole 114b and is inserted into the second shaft hole 11d to connect the second support base 7 to the second end 11b. The second shaft 72 can be connected to the outer shell 114 or the second bracket assembly 1154 by snap-fit, magnetic connection, or other means; this application does not impose specific limitations on this. Understandably, in the first state, the second shaft 72 is inserted into the second shaft hole 11d and forms a detachable connection with the outer shell 114, thereby placing the second support base 7 at the second end 11b.

[0102] Furthermore, such as Figure 7As shown, the first shaft 62 is a hollow cylinder with a receiving cavity 62a formed inside. Understandably, in the second state, the second shaft 72 is inserted into the receiving cavity 62a and joined together with the first support base 6, thereby connecting the second support base 72 to the first support base 6. The second shaft 72 can be connected to the first support base 6 by snap-fit, magnetic connection, or other methods; this application does not impose specific limitations on this.

[0103] Please see Figure 3 In this embodiment, the heating element 2 includes a heating tube 21 and a fin assembly 22, with the fin assembly 22 passing through and installed on the heating tube 21. Through this arrangement, the heat generated by the heating tube 21 can be transferred to the fin assembly 22, and heat exchange is achieved through the contact between the fin assembly 22 and the air. The fin assembly 22 includes multiple fins, thus increasing the heat exchange area between the fins and the air, improving heat exchange efficiency, and thereby enhancing the heating effect of the heater 100. A heat-conducting plate 3 is connected to the heating tube 21. Since the heating tube 21 is the component that directly generates heat, this arrangement allows for faster and more uniform heat conduction, which is beneficial for improving the heating performance of the heater 100. This application does not specifically limit the placement of the heat-conducting plate 3; the heat-conducting plate 3 can also be fixedly connected to the temperature limiter 4.

[0104] More specifically, such as Figure 3 As shown, the heating element 21 extends through the fin assembly 22 at both ends along its length, forming protruding ends, namely the first protruding end 21a and the second protruding end 21b. The first protruding end 21a of the heating element 21 is connected to the first support assembly 1151; the second protruding end 21b of the heating element 21 is connected to the second support assembly 1154. This arrangement fixes the heating element 2 within the heating chamber 111a, which helps to improve the connection strength and firmness between the heating element 2 and the support assembly 115. This arrangement avoids affecting the heat exchange effect of the fins due to the heat-conducting plate 3 without affecting the heat conduction of the heat-conducting plate 3, thus ensuring the heat exchange effect and guaranteeing that the heating effect of the heater 100 is not affected.

[0105] Please see Figures 4 to 6 as well as Figure 8In some embodiments, the heat-conducting plate 3 is connected to the second protruding end 21b of the heating element 21. Understandably, when the heater 100 is in the second state, the second protruding end 21b is located in the upper half of the heater 100, that is, the heat-conducting plate 3 is located in the upper half of the heater 100. After the heating element 21 heats the air in the heating chamber 111a, because the high-temperature air is lighter, the heat will accumulate upwards. When the heater 100 is in the second state, the second protruding end 21b of the heating element 21 is located in a higher position, meaning that the temperature of the second protruding end 21b of the heating element 21 will be higher than the temperature of the first protruding end 21a. Placing the heat-conducting plate 3 at the second protruding end 21b makes it easier for the temperature limiter 4 to sense temperature changes, allowing the temperature limiter 4 to react more quickly, thereby ensuring the safe use of the heater 100 and further improving the safety performance of the heater 100.

[0106] Furthermore, the distance between the heat-conducting plate 3 and the end face of the second protruding end 21b is no greater than one-third of the total length of the heating tube 21 (i.e., the dimension of the heating tube 21 in the length direction). In this way, the heat exchange effect of the fins can be avoided due to the heat-conducting plate 3, which helps to improve the heating effect of the heater 100.

[0107] Please see Figure 9 and combined Figure 8 In some embodiments, the temperature limiter 4 further includes a wiring portion 43, which is located on the opposite side of the temperature sensing portion 41. It can be understood that the wiring portion 43 is located on the side of the mounting bracket away from the heat-conducting plate 3, i.e., the wiring portion 43 is located inside the electrical cavity 111b. This arrangement prevents the wiring portion 43 from being exposed inside the heating cavity 111a, avoiding moisture from entering the heating cavity 111a through the air inlet 112 or the heat radiation outlet 113 and adhering to the wiring portion 43, thus reducing the risk of electric shock and short circuits and improving the safety of the heater 100.

[0108] In some implementations, see reference to Figure 4 and Figure 6 The limiter is located at the second end 11b of the housing 11. Specifically, the limiter is mounted on the second mounting bracket 1155, which has a through hole through which the temperature sensing part 41 of the temperature limiter 4 can extend into the heating chamber 111a to make thermal contact with the heat-conducting plate 3. Furthermore, by placing the limiter at the second end 11b, the wiring part 43 of the limiter is located on the side of the second mounting bracket 1155 away from the heat-conducting plate 3, that is, the wiring part 43 is located in the main control cavity 111b2. Since the main control cavity 111b2 is located at the second end 11b, the wiring distance is significantly shortened, which facilitates wiring and makes it easier to connect the temperature limiter 4 to the working circuit of the heating component 2. It also improves the safety of the power wiring.

[0109] Please refer to the following: Figures 10 to 13In other embodiments, the heat-conducting plate 3 is connected to the first extended end 21a of the heating tube 21. Understandably, when the heater 100 is in the second state, the first extended end 21a is located in the lower half of the heater 100, that is, the heat-conducting plate 3 is located in the lower half of the heater 100. After the heating tube 21 heats the air in the heating chamber 111a, because the high-temperature air is lighter, the heat will accumulate upwards. When the heater 100 is in the second state, the first extended end 21a of the heating tube 21 is located in a lower position, meaning that the temperature of the second extended end 21b of the heating tube 21 will be higher than the temperature of the first extended end 21a. Therefore, the effect of placing the heat-conducting plate 3 at the first extended end 21a is slightly worse than that of placing it at the second extended end 21b, but it still improves the safety performance of the heater 100.

[0110] Furthermore, the distance between the heat-conducting plate 3 and the end face of the first protruding end 21a is no greater than one-third of the total length of the heating tube 21 (i.e., the dimension of the heating tube 21 in the length direction). In this way, the heat exchange effect of the fins can be avoided due to the heat-conducting plate 3, which helps to improve the heating effect of the heater 100.

[0111] In some implementations, see reference to Figures 10 to 13 The limiter is located at the first end 11a of the housing 11. Specifically, the limiter is mounted on the first mounting bracket 1152, which has a through hole through which the temperature sensing part 41 of the thermostat 4 can extend into the heating chamber 111a to make thermal contact with the heat-conducting plate 3. Furthermore, by placing the limiter at the first end 11a, the wiring part 43 of the limiter is located on the side of the first mounting bracket 1152 away from the heat-conducting plate 3, that is, the wiring part 43 is located inside the motor cavity 111b1. In this way, the wiring part 43 can be hidden, avoiding the wiring part 43 being exposed inside the heating chamber 111a, reducing the risk of electric shock and short circuit, and improving the safety of the heater 100.

[0112] Alternatively, in an alternative embodiment, heat-conducting plates 3 are provided at both the first protruding end 21a and the second protruding end 21b of the heating element 21, and a temperature limiter 4 is provided at each of the first end 11a and the second end 11b of the housing 11 to make thermal contact with the two heat-conducting plates 3 respectively. In this way, by providing two temperature limiters 4 to protect the working circuit of the heater 100, the problem of protection failure due to the failure of the temperature limiter 4 can be avoided, further improving the safety performance of the heater 100.

[0113] Please see Figure 8 and Figure 13In this embodiment, the heat-conducting sheet 3 includes a heat-conducting substrate 31, which is the main structure of the heat-conducting sheet 3. The heat-conducting substrate 31 is typically made of a material with good thermal conductivity, such as a metal, specifically aluminum alloy or stainless steel. The heat-conducting substrate 31 has mounting holes 3a, through which the heat-conducting sheet 3 is fitted onto the heating tube 21. Thus, no additional mounting structure is required, resulting in a simple structure that is easy to manufacture.

[0114] In some embodiments, the heat-conducting sheet 3 further includes a sleeve 32, which surrounds the mounting hole 3a and is connected to the heat-conducting substrate 31. The heating element 21 passes through the mounting hole 3a and the sleeve 32, and the sleeve 32 is fixedly connected to the heating element 21. The sleeve 32 can be riveted to the heating element 21, ensuring tight contact between them and improving heat conduction; it also ensures a secure connection between the heat-conducting sheet 3 and the heating element 21, preventing the heat-conducting sheet 3 from moving on the heating element 21.

[0115] In some embodiments, the heat-conducting substrate 31 and the sleeve 32 are integrally formed. This integral forming process facilitates the fabrication of the heat-conducting sheet 3 and also helps improve the connection strength between the heat-conducting substrate 31 and the sleeve 32, as well as the reliability of the heat-conducting sheet 3. The integral forming method includes, but is not limited to, integral casting.

[0116] Please see Figure 8 and Figure 13 In some embodiments, the heater 100 further includes a fastener 5, the heat-conducting substrate 31 is provided with a connecting hole 3b, and the temperature limiter 4 includes a connecting part 42. The fastener 5 passes through the connecting hole 3b and connects to the connecting part 42, thereby fixing the heat-conducting sheet 3 and the temperature limiter 4 together. The fastener 5 can be a screw, a snap-fit, etc., and this application does not impose specific limitations on it. Through the above arrangement, the heat-conducting sheet 3 and the temperature-sensing part 41 are in close contact, effectively preventing gaps from forming between them, thereby helping to improve the safety performance of the heater 100.

[0117] In this embodiment, a thermally conductive adhesive (not shown in the figure) is provided between the heat-conducting sheet 3 and the temperature-sensing part 41. This prevents gaps from forming between the heat-conducting sheet 3 and the temperature-sensing part 41, effectively avoiding any impact on heat transfer performance due to gaps; it also enables more efficient and rapid heat conduction. It should be noted that this application does not specifically limit the type of thermally conductive adhesive, which includes, but is not limited to, epoxy resin thermally conductive adhesive, silicone thermally conductive adhesive, and thermal grease.
