DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] Please refer to Figure 1-3 An embodiment of the present application provides a heater 1, including a host 10 and a base 20; the host 10 includes a casing 11, a heating component 12, a wind wheel 13 and a motor 14.

[0028] The casing 11 has a housing cavity 11A and a heat radiation port 11B connected to the housing cavity 11A. The heating component 12, the wind wheel 13 and the motor 14 are all arranged in the housing cavity 11A, so that the housing 11 is used to protect the heating component 12, the wind wheel 13 and the motor 14, and the probability of damage to the heating component 12, the wind wheel 13 and the motor 14 can be reduced, so that the heating component 12, the wind wheel 13 and the motor 14 can have a longer service life, and then the heater 1 can have a longer service life. Exemplarily, the material of the casing 11 can be but not limited to metal or plastic. In the embodiment of the present application, the material of the casing 11 is not specifically limited. Exemplarily, the shape of the casing 11 can be but not limited to a cube, a cuboid, a cylinder and a truncated cone. In the embodiment of the present application, the shape of the casing 11 is not specifically limited.

[0029] It is understandable that the casing 11 can be the entire outer shell of the heater 1 , or it can be the internal shell of the heater 1 , such as the volute of the wind wheel 13 .

[0030] The heating component 12 can generate heat, and the heat can be radiated to the outside of the housing 11 through the heat radiation port 11B. Specifically, the heating component 12 may include a heating element and fins. Exemplarily, the form of the heating element may 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, and an electric heating wire heating element. In the embodiment of the present application, the specific form of the heating element is not limited.

[0031] The wind wheel 13 is disposed in the accommodating chamber 11A and is rotatably connected to the housing 11. When the wind wheel 13 rotates, it can drive the airflow to flow through the heating component 12 and blow out from the heat radiation port 11B. For example, the wind wheel 13 can be, but is not limited to, an axial flow wind wheel, a centrifugal wind wheel, and a cross-flow wind wheel.

[0032] The motor 14 is connected to the housing 11 and is drivingly connected to the wind wheel 13 for driving the wind wheel 13 to rotate.

[0033] Please refer to Figure 1-3Specifically, the housing 11 has a length direction, and the housing 11 includes a first side wall 11C and a second side wall 11D. The first side wall 11C is located at the end of the housing 11 along the length direction, and the second side wall 11D is arranged at an angle with the first side wall 11C; the base 20 can be selectively connected to one of the first side wall 11C and the second side wall 11D, so that the heater 1 has a first use state in which the first side wall 11C is connected through the base 20 and the host 10 is supported (please refer to Figure 1 ), and a second use state where the base 20 is connected to the second side wall 11D and supports the host 10 (see Figure 2 ). The extension direction of the rotating shaft of the wind wheel 13 is configured to be a vertical direction in at least one of the first use state and the second use state. In the following embodiments of this application, the first use state of the heater 1 is taken as an example for explanation.

[0034] For example, the base 20 can be selectively snap-connected with one of the first side wall 11C and the second side wall 11D; of course, the base 20 can also be selectively screw-connected with one of the first side wall 11C and the second side wall 11D. In the embodiment of the present application, there is no specific limitation on the connection method between the base 20 and the first side wall 11C and the second side wall 11D.

[0035] Please refer to Figure 1-3 In an optional embodiment, the output shaft of the motor 14 is connected to the upper end of the rotating shaft of the wind wheel 13 in the vertical direction, that is, the motor 14 is arranged on the side of the wind wheel 13 away from the base 20 to reduce the force borne by the output shaft of the motor 14, thereby reducing the amplitude of the vibration of the output shaft of the motor 14, so that the wind wheel 13 can run smoothly, and then the probability of vibration of the main unit 10 can be reduced to improve the stability of the operation of the heater 1.

[0036] Please refer to Figure 3 It can be understood that the motor 14 is located in the accommodating chamber 11A, and the axis of the output shaft of the motor 14 can coincide with the axis of the rotating shaft of the wind wheel 13. At this time, the output shaft of the motor 14 and the rotating shaft of the wind wheel 13 can be connected by a coupling.

[0037] It can be understood that the motor 14 is located in the accommodating chamber 11A, and the axis of the output shaft of the motor 14 can also be parallel to the axis of the rotating shaft of the wind wheel 13. At this time, the output shaft of the motor 14 can be connected to the rotating shaft of the wind wheel 13 through a transmission structure.

[0038] Exemplarily, the transmission structure may include a first spur gear and a second spur gear, wherein the first spur gear is connected to the rotating shaft of the wind wheel 13; the second spur gear is connected to the output shaft of the motor 14 and meshes with the first spur gear.

[0039] Exemplarily, the transmission structure may also be a first pulley, a second pulley and a transmission belt, wherein the first pulley is connected to the rotating shaft of the wind wheel 13; the second pulley is connected to the output shaft of the motor 14, and is connected to the first pulley through a transmission belt.

[0040] Please refer to Figure 4 It can be understood that the axis of the output shaft of the motor 14 can also be set at an angle with the axis of the rotating shaft of the wind wheel 13. The main body of the motor 14 is located outside the casing 11, and the output shaft of the motor 14 extends into the accommodating cavity 11A. The output shaft of the motor 14 and the rotating shaft of the wind wheel 13 can be connected through a transmission structure.

[0041] For example, the transmission structure may include a universal joint, the two ends of which are respectively connected to the rotating shaft of the wind wheel 13 and the output shaft of the motor 14, and the motor 14 may also drive the wind wheel 13 to rotate, so as to drive the air flow to flow through the heating component 12 and blow out from the heat radiation port 11B. The probability of the host 10 shaking can also be reduced to improve the stability of the operation of the heater 1.

[0042] Exemplarily, the transmission structure may also include a turbine and a worm gear, wherein the turbine is connected to the rotating shaft of the wind wheel 13; the worm gear is connected to the output shaft of the motor 14 and meshes with the turbine, so that the motor 14 can drive the wind wheel 13 to rotate, thereby driving the airflow to flow through the heating component 12 and be blown out from the heat radiation port 11B.

[0043] For example, the transmission structure may further include a first bevel gear and a second bevel gear, wherein the first bevel gear is connected to the rotating shaft of the wind wheel 13; the second bevel gear is connected to the output shaft of the motor 14 and meshes with the first bevel gear, so that the motor 14 can also drive the wind wheel 13 to rotate, so as to drive the airflow to flow through the heating component 12 and blow out from the heat radiation port 11B. In addition, the probability of the host 10 shaking is reduced to improve the stability of the operation of the heater 1.

[0044] It can be understood that the host 10 can also be directly supported by the first side wall 11C and the second side wall 11D. At this time, the heater 1 has a first use state in which the host 10 is supported by the first side wall 11C, and a second use state in which the host 10 is supported by the second side wall 11D. Thus, there is no need for the base 20, which reduces the use of parts of the heater 1, reduces the cost of the heater 1, and also improves the ease of use of the heater 1.

[0045] Please refer to Figure 4 In an optional embodiment, the host 10 also includes a control circuit board (not shown in the figure). The control circuit board is arranged in the accommodating cavity 11A, and is connected to the side of the casing 11 away from the base 20, and is electrically connected to the motor 14. By placing the control circuit board on the side close to the motor 14, the conductive wires between the control circuit board and the motor 14 can be reduced to reduce the cost of the heater 1.

[0046] Furthermore, the host 10 also includes a control panel (not shown in the figure), which is connected to the housing 11 and is arranged on a side of the housing 11 away from the base 20, and is electrically connected to the control circuit board. Since the control panel is arranged on a side of the housing 11 away from the base 20, when the heater 1 is in the first use state, the control panel is closer to the user's hand position, which is convenient for the user to operate the control panel and improves the user's convenience in operating the heater 1. Exemplarily, the control panel can have mechanical components such as buttons and turntables, and can also have a touch display screen. In the embodiment of the present application, there is no limitation on the specific form of the control panel.

[0047] Please refer to Figure 5 In an optional embodiment, the output shaft of the motor 14 is connected to the lower end of the rotating shaft of the wind wheel 13 in the vertical direction, and the axis of the output shaft of the motor 14 and the axis of the rotating shaft of the wind wheel 13 are not arranged colinearly, which can also reduce the force borne by the rotating shaft of the motor 14 and improve the operating stability of the heater 1.

[0048] Exemplarily, the axis of the output shaft of the motor 14 may be arranged parallel to the axis of the rotating shaft of the wind wheel 13 , and the output shaft of the motor 14 may be connected to the rotating shaft of the wind wheel 13 via a transmission structure.

[0049] Of course, the axis of the output shaft of the motor 14 can also be set at an angle with the axis of the rotating shaft of the wind wheel 13, and the output shaft of the motor 14 can be connected to the rotating shaft of the wind wheel 13 through a transmission structure to reduce the force borne by the output shaft of the motor 14, thereby reducing the amplitude of the vibration of the output shaft of the motor 14, so that the wind wheel 13 can run smoothly, and further reduce the probability of vibration of the host 10, so as to improve the stability of the operation of the heater 1. The specific form of the transmission structure will not be described in detail here.

[0050] Please refer to Figure 3-5 In some embodiments, the housing 11 includes a shell 111, a first bracket 112 and a second bracket 113. The shell 111 has a receiving cavity 11A and a heat radiation port 11B. The first bracket 112 and the second bracket 113 are both disposed in the receiving cavity 11A and connected to the shell 111. The two ends of the wind wheel 13 are detachably connected to the first bracket 112 and the second bracket 113, respectively, so as to facilitate the disassembly and installation of the wind wheel 13, so as to reduce the maintenance cost of the wind wheel 13, thereby reducing the maintenance cost of the heater 1. The two ends of the wind wheel 13 are rotatably connected to the first bracket 112 and the second bracket 113, respectively. Exemplarily, the first bracket 112 and the second bracket 113 are both provided with bearing structures to reduce the friction between the wind wheel 13 and the first bracket 112 and the second bracket 113, so as to facilitate the motor 14 to drive the wind wheel 13 to rotate.

[0051] Please refer to Figure 3-5 In some embodiments, the shell 111 includes a main body 1111 and two end cover parts 1112, the two end cover parts 1112 are respectively connected to the two sides of the main body 1111, the two end cover parts 1112 and the main body 1111 are surrounded by a receiving cavity 11A, the end cover part 1112 is provided with a receiving cavity 1112A, and the motor 14 is at least partially arranged in the receiving cavity 1112A, so as to prevent the temperature of the motor 14 from being too high, so as to reduce the probability of damage to the motor 14, so that the motor 14 can have a longer service life, and then the heater 1 can have a longer service life.

[0052] It is understandable that the control circuit board can also be placed in the accommodating cavity 1112A to prevent the temperature of the control circuit board from being too high, thereby reducing the probability of damage to the control circuit board and enabling the heater 1 to have a longer service life.

[0053] It can be understood that the end cover 1112 can be detachably connected to the main body 1111 to facilitate the installation of the motor 14 and the transmission structure, which can improve the installation efficiency of the motor 14 and the transmission structure, and thus improve the assembly efficiency of the heater 1. Exemplarily, the connection method between the end cover 1112 and the main body 1111 includes at least one of a screw connection and a clamping connection. In the embodiment of the present application, there is no limitation on the detachable connection method between the end cover 1112 and the main body 1111.

[0054] It can be understood that since the end cover portion 1112 can be detachably connected to the main body portion 1111, when the motor 14 and the transmission structure need to be replaced or repaired, the end cover portion 1112 can be directly removed to expose the motor 14 and the transmission structure, thereby improving the replacement or repair efficiency of the motor 14 and the transmission structure.
