The bottom of the base 1 is usually designed with anti-slip pads or anti-slip textures to increase the friction between the base 1 and the ground and prevent the heater from sliding or tipping over during use.

[0053] The first rotating component 2 is connected to the base 1.

[0054] In this embodiment of the invention, the first rotating component 2 can be connected to the base 1, and the first rotating component 2 can rotate relative to the base 1.

[0055] The second rotating component 3 is connected to the first rotating component 2.

[0056] In this embodiment of the invention, the second rotating component 3 can be connected to the first rotating component 2, and the second rotating component 3 can rotate relative to the first rotating component 2.

[0057] Air outlet duct 4 is connected to the second rotating assembly 3.

[0058] In this embodiment of the invention, the air outlet duct 4 can be connected to the second rotating component 3. When the user uses the heater, warm air is emitted through the air outlet duct 4 to obtain warmth.

[0059] The air outlet duct 4 is an important component of the heater, used to guide and concentrate the flow of hot air, ensuring that the hot air can be delivered efficiently and evenly to the desired area. The design and function of the air outlet duct 4 directly affect the performance, comfort, and aesthetics of the heater.

[0060] The main functions of the air outlet duct 4 are as follows: Air Guiding: The main function of the air outlet duct 4 is to guide and concentrate the flow of hot air. By designing different shapes and angles, the air outlet duct 4 can evenly distribute hot air to the required area, ensuring the coverage and uniformity of the hot air flow. Hot Air Concentration: The design of the air outlet duct 4 can concentrate the flow of hot air, reduce heat loss, and improve the utilization efficiency of hot air. By concentrating the hot air, the air outlet duct 4 can ensure that hot air can be efficiently delivered to the required area, improving the heating effect. Noise Control: The design of the air outlet duct 4 can reduce the noise generated by air flow. By optimizing the shape and internal structure of the air outlet duct 4, the air outlet duct 4 can reduce air flow resistance and reduce noise generation. Aesthetic Decoration: The design of the air outlet duct 4 also serves an aesthetic decoration purpose. By selecting different materials, colors, and shapes, the air outlet duct 4 can match the appearance style of the heater, enhancing the overall aesthetics. Safety Protection: The design of the air outlet duct 4 can prevent users' fingers or other objects from accidentally entering the heater, avoiding safety hazards. The opening of the air duct 4 is usually designed to be small enough to prevent fingers or other objects from entering.

[0061] Common designs for air ducts (4) include: Material: Air ducts (4) are typically made of metal (such as aluminum alloy or stainless steel) or plastic. Metal materials offer higher strength and durability, while plastic materials are lighter and less expensive. Shape: Air ducts (4) come in various shapes, commonly including cylindrical, square, and conical. Different shapes are suitable for different heaters and application scenarios.

[0062] The first rotating component 2 is used to control the second rotating component 3 to rotate in the vertical direction, so that the second rotating component 3 drives the air outlet duct 4 to rotate in the vertical direction.

[0063] In this embodiment of the invention, the function of the first rotating component 2 is to control the second rotating component 3 to rotate in the vertical direction. When the second rotating component 3 rotates in the vertical direction, the second rotating component 3 can drive the air outlet duct 4 to rotate in the vertical direction as well.

[0064] The second rotating component 3 is used to control the rotation of the air outlet duct 4.

[0065] In this embodiment of the invention, the function of the second rotating component 3 is to control the air outlet 4 to rotate in the horizontal direction. Thus, through the design of the first rotating component 2 and the second rotating component 3, the air outlet 4 can rotate not only in the horizontal direction but also in the vertical direction. As a result, the user can not only warm the lower body but also the upper body, which increases the user's experience.

[0066] In one embodiment, a connecting rod 21 is fixedly connected to a base 1 at its first end; a first rotating shaft 22 is connected to a second end of the connecting rod 21 at its first end; and a second rotating assembly 3 includes: an air outlet housing 31, the first end of which is rotatably connected to a first end of an air outlet 4 at its inner end; the outer side of the air outlet housing 31 is connected to a second end of the first rotating shaft 22; and a second rotating shaft 32, the first end of which is connected to a second end of the air outlet 4 at its second end.

[0067] Specifically, the first end of the connecting rod 21 is fixedly connected to the base 1, thereby supporting the entire body. The first end of the first rotating shaft 22 is connected to the second end of the connecting rod 21, and the outer side of the air outlet casing 31 is connected to the second end of the first rotating shaft 22. Thus, when the first rotating shaft 22 rotates, it drives the air outlet casing 31 to rotate relative to the connecting rod 21. The first end inside the air outlet casing 31 is rotatably connected to the first end of the air outlet 4. The first end of the second rotating shaft 32 is connected to the second end of the air outlet 4, and the second end of the second rotating shaft 32 is connected to the second end of the air outlet 4. Thus, when the second rotating shaft 32 rotates, it drives the air outlet 4 to rotate relative to the air outlet casing 31.

[0068] The connecting rod 21 is an important component of the heater, used to connect and secure the various parts of the heater, ensuring its stability and safety during use. The design and function of the connecting rod 21 directly affect the structural strength, stability, and service life of the heater.

[0069] The main functions of connecting rod 21 are as follows: Structural support: The main function of connecting rod 21 is to provide structural support for the various components of the heater, ensuring that the heater will not deform or be damaged during use. Connecting rod 21 typically connects the heater body, base 1, air outlet 4, and other components to form a stable overall structure. Fixing function: Connecting rod 21 securely connects the various components of the heater together using bolts, nuts, or other fixing devices, preventing components from loosening or shifting during use. Improved stability: The design of connecting rod 21 can improve the overall stability of the heater, preventing it from tipping over or shaking during use. Connecting rod 21 is usually designed with a robust and stable structure to ensure the heater remains stable during use. Safety guarantee: The design of connecting rod 21 can ensure the safety of the heater, preventing components from falling off or being damaged during use, avoiding safety hazards. Connecting rod 21 is usually designed with high-strength and durable materials to ensure stability under various operating conditions.

[0070] Common designs for connecting rod 21 include: Material: Connecting rod 21 is typically made of metal (such as steel or aluminum) or high-strength plastic. Metal connecting rods 21 offer higher strength and durability, while plastic connecting rods 21 are lighter and less expensive. Shape: Connecting rod 21 is usually cylindrical or rectangular, designed for a robust and stable structure. The length and diameter of the connecting rod 21 are designed according to the size and structural requirements of the heater. Fixing Device: Connecting rod 21 is usually designed with bolt holes or other fixing devices for connecting it to various components of the heater. The fixing device should be designed to ensure a firm and reliable fit, preventing the connecting rod 21 from loosening or shifting during use. Anti-slip Design: The bottom of the connecting rod 21 is usually designed with an anti-slip pad or anti-slip texture to increase friction between the connecting rod 21 and the ground, preventing the heater from sliding or tipping over during use. Adjustable Design: Some connecting rods 21 are designed to be adjustable, allowing users to adjust the length and angle of the connecting rod 21 as needed to adapt to different installation environments and usage requirements. The adjustable design increases the flexibility and adaptability of the heater.

[0071] In one embodiment, the heater may further include a tilt switch 6, which is disposed on the second side of the base 1; the second side of the base 1 is the side of the base 1 facing away from the air outlet duct 4, and the tilt switch 6 is used to put the heater into a power-off state when the heater is tilted.

[0072] Specifically, a tilt switch 6 is installed on the ground of the base 1 of the heater. When the heater tilts and reaches a certain tilt angle, the tilt switch will cut off the power to the heater. Alternatively, when the heater tipes over, the tilt switch will cut off the power to the heater. This tilt switch provides safety protection for the heater.

[0073] The tilt switch in a space heater is a safety device used to detect the heater's tilt status and automatically shut off the power when the heater tilts or tipes over, preventing fires or other safety accidents. The design and function of the tilt switch directly affect the safety and reliability of the space heater.

[0074] The main functions of a tilt switch include: Tilt detection: The tilt switch primarily detects the tilt status of the heater. When the heater tilts or falls over, the tilt switch senses the tilt angle and triggers the corresponding safety mechanism. Automatic power cut-off: When the tilt switch detects that the heater is tilted or falling over, it automatically cuts off the power supply to prevent the heater from continuing to operate, thereby avoiding fire or other safety accidents. Safety protection: The tilt switch is designed to ensure the safety of the heater, preventing it from continuing to operate in a tilted or fallen state and avoiding safety hazards. Tilt switches are typically designed as highly sensitive and reliable devices to ensure effective operation under various usage conditions.

[0075] Common designs for tilt switches include: Installation location: Tilt switches are typically installed at the bottom of the heater or inside the unit to ensure accurate detection of the heater's tilt status. Sensitivity: The sensitivity design of the tilt switch directly affects its detection performance. Tilt switches are usually designed for high sensitivity, responding quickly and triggering safety mechanisms when the heater tilts or tipps over. Reliability: The tilt switch design should ensure high reliability, operating stably under various usage conditions. Tilt switches typically use high-quality materials and manufacturing processes to ensure durability and reliability. Waterproof and dustproof: Some tilt switches are designed to be waterproof and dustproof, suitable for humid or dusty environments. Waterproof and dustproof design protects the tilt switch from external environmental influences, extending its service life.

[0076] In one embodiment, the heater may further include an air outlet grille 7, which is disposed on the side of the air outlet duct 4 facing away from the connecting rod 21.

[0077] Specifically, an air outlet grille 7 can be provided on the side of the air outlet duct 4 facing away from the connecting rod 21 to control and guide airflow, ensuring that the equipment can efficiently and evenly deliver hot air to the surrounding environment. The design and function of the air outlet grille 7 directly affect the performance, comfort, and aesthetics of the equipment.

[0078] The main functions of the air vent grille 7 include: Air Guidance: The primary function of the air vent grille 7 is to control and guide the direction of airflow. By designing different grille shapes and angles, the air vent grille 7 can evenly distribute air to the desired area, ensuring the coverage and uniformity of airflow. Air Filtration: Some air vent grilles 7 are designed with built-in filters or screens to filter dust, particulate matter, and other pollutants from the air, improving air quality and protecting user health. Noise Control: The design of the air vent grille 7 can reduce noise generated during airflow. By optimizing the shape and spacing of the grille, the air vent grille 7 can reduce airflow resistance and reduce noise generation. Aesthetic Decoration: The design of the air vent grille 7 can also serve an aesthetic decoration purpose. By choosing different materials, colors, and shapes, the air vent grille 7 can match the appearance style of the equipment, enhancing the overall aesthetics. Safety Protection: The design of the air vent grille 7 can prevent users' fingers or other objects from accidentally entering the equipment, avoiding safety hazards. The spacing of the grille is usually designed to be small enough to prevent fingers or other objects from entering.

[0079] The air vent grille 7 is typically made of metal (such as aluminum alloy or stainless steel) or plastic. Metal materials offer higher strength and durability, while plastic materials are lighter and less expensive.

[0080] In one embodiment, the first rotating component 2 may further include: a first stepper motor (not shown in the figure), which is disposed inside the second rotating shaft 32. The first stepper motor is used to control the rotation of the second rotating shaft 32, so that the second rotating shaft 32 drives the air outlet 4 to rotate.

[0081] Specifically, the second rotating shaft 32 of the present invention may be equipped with a first stepper motor, which is mainly used to drive the second rotating shaft 32 to rotate, thereby causing the second rotating shaft 32 to drive the air outlet 4 to rotate.

[0082] In one embodiment, a handle 8 is provided at one end of the air outlet casing 31. The user can lift or move the heater using the handle 8.

[0083] In one embodiment, the heater further includes a third rotating shaft 5, the first end of which is connected to the first end of the connecting rod 21, and the second end of which is connected to the first surface of the base 1. The first surface of the base 1 is the surface of the base 1 facing the air outlet duct 4. The third rotating shaft 5 is used to control the rotation of the connecting rod 21, so that the connecting rod 21 drives the air outlet duct 4 to rotate.

[0084] Specifically, such as Figure 2 As shown, a structural block diagram of another heater provided by an embodiment of the present invention is shown. The first end of the third rotating shaft 5 is connected to the first end of the connecting rod 21, and the second end of the third rotating shaft 5 is connected to the upper side of the base 1. Thus, when the third rotating shaft 5 rotates, it drives the connecting rod 21 to rotate relative to the base 1, thereby causing the connecting rod 21 to drive the air outlet 4 to rotate.

[0085] In one embodiment, the heater may further include: a second stepper motor (not shown in the figure), which is disposed in the third rotating shaft 5. The second stepper motor is used to control the rotation of the connecting rod 21, so that the connecting rod 21 drives the air outlet 4 to rotate.

[0086] Specifically, the third rotating shaft 5 of the present invention may be equipped with a second stepper motor, which is mainly used to drive the third rotating shaft 5 to rotate, thereby driving the connecting rod 21 to rotate relative to the base 1 when the third rotating shaft 5 rotates, and then causing the connecting rod 21 to drive the air outlet 4 to rotate.

[0087] like Figure 3 The diagram shows a structural block diagram of a capacitor provided in an embodiment of the present invention.

[0088] In one embodiment, the heater further includes: a capacitor ( Figure 1(Not shown in the image), the capacitor includes a first electrode and a second electrode; the capacitor is disposed inside the first rotating shaft 22; the first electrode is fixedly connected to the air outlet housing 31, and the first electrode is a strip electrode; the second electrode is fixedly connected to the connecting rod 21, and the second electrode is a circular rotating electrode; the first preset area of ​​the second electrode is the first dielectric, and the second preset area of ​​the second electrode is the second dielectric; the first electrode and the second electrode maintain a preset distance.

[0089] Specifically, the capacitor is disposed inside the first rotating shaft 22. The capacitor may include a first electrode in the form of a strip electrode and a second electrode in the form of a circular disc. The first electrode is disposed on the air outlet housing 31 and can be fixed in position, moving with the air outlet housing 31 in a clockwise motion. The second electrode can be disposed on the connecting rod 21 and kept in a fixed position. A preset distance is maintained between the first and second electrodes, i.e., the first and second electrodes do not contact each other. In the second electrode, air can be used as the medium for the two electrodes in the vertical upper and lower fan-shaped regions, while ceramic medium can be used as the medium for the two electrodes in the horizontal left and right fan-shaped regions.

[0090] like Figure 4 The diagram shows a structural block diagram of a capacitance detection circuit provided in an embodiment of the present invention.

[0091] In one embodiment, the heater further includes: a capacitance detection circuit ( Figure 1 (Not shown in the image), a capacitance detection circuit is located inside the air outlet casing 31. The capacitance detection circuit is connected to both the first and second electrodes and is used to detect the capacitance value generated by the first and second electrodes; control chip ( Figure 1 (Not shown in the image) The control chip is located inside the air outlet casing 31. The control chip is used to obtain the capacitance value detected by the capacitance value check circuit, determine the position state of the air outlet 4 based on the capacitance value, determine the sweeping angle of the air outlet 4 based on the position state of the air outlet 4, and control the air outlet 4 to sweep according to the sweeping angle.

[0092] Specifically, the capacitance detection circuit can be located inside the air outlet casing 31. This circuit can be connected to both the first and second electrodes. The projected area of ​​the first and second electrodes relative to each other can be denoted as S. According to the capacitance calculation formula: C = ∈ * S / d, where C is the capacitance value generated by the first and second electrodes, ∈ is the dielectric constant, S is the projected area of ​​the first and second electrodes relative to each other, and d is the preset distance between the first and second electrodes. Under the condition that the preset distance d between the first and second electrodes remains constant, when the first electrode rotates with the air outlet casing 31 to a different medium position corresponding to the second electrode, the dielectric constant ∈ changes accordingly based on the different conductive media between the electrodes, and the capacitance value C changes accordingly. The corresponding capacitance value is input to the control chip through the capacitance detection circuit, and the control chip can determine the position state of the air outlet 4 based on the capacitance value.

[0093] In one embodiment, the control chip is used to determine that the position of the air duct 4 is vertical when the capacitance value is within a first preset range, and to determine that the position of the air duct 4 is horizontal when the capacitance value is within a second preset range.

[0094] In one embodiment, the control chip is used to control the sweeping angle of the air outlet duct 4 to be within a first preset range when the air outlet duct 4 is in a vertical state, and to control the air outlet duct 4 to sweep air at the sweeping angle within the first preset range; and to control the air outlet duct 4 to sweep air at the sweeping angle within the second preset range when the air outlet duct 4 is in a horizontal state.

[0095] Specifically, such as Figure 5 The diagram illustrates a flowchart of the steps for determining the sweeping angle of an air outlet duct according to an embodiment of the present invention. The control chip first acquires the capacitance value detected by the capacitance detection circuit. Based on the capacitance value, it determines the position of the air outlet duct. When the capacitance value is within a first preset range, the position of the air outlet duct is determined to be vertical, and the sweeping angle of the air outlet duct is determined to be within the first preset range. The control chip can then control the air outlet duct to sweep within the first preset range, for example, 60° to the left and right within the first preset range, meaning the sweeping range is 120°. When the capacitance value is within a second preset range, the position of the air outlet duct is determined to be horizontal, and the sweeping angle of the air outlet duct is determined to be within the second preset range. The control chip can then control the air outlet duct to sweep within the second preset range, for example, 60° upward and 30° downward within the second preset range, meaning the sweeping range is 90°.

[0096] like Figure 6 The diagram illustrates a vertical air outlet configuration according to an embodiment of the present invention. Figure 7 The diagram illustrates a horizontal air outlet duct according to an embodiment of the present invention. By controlling the position of the air outlet duct 4, the air outlet duct 4's sweeping angle can be better suited to the user's actual usage needs, simplifying the overall system space, reducing user operation steps, and greatly improving the user experience.

[0097] In this embodiment of the invention, the heater includes: a base; a first rotating assembly connected to the base; a second rotating assembly connected to the first rotating assembly; and an air outlet connected to the second rotating assembly. The first rotating assembly controls the second rotating assembly to rotate vertically, thereby causing the second rotating assembly to drive the air outlet to rotate vertically. The second rotating assembly controls the rotation of the air outlet. Thus, the air outlet can rotate in multiple directions via the first and second rotating assemblies, allowing the user to warm not only the lower body but also the upper body, enhancing the user experience.
