[0038] Example

[0039] Please refer to the following: Figure 1 and Figure 2 This embodiment provides a heater, specifically a 180-degree no-dead-angle heater, which includes a base 100 and a drive assembly 200 (see...). Figure 3 ) and at least two 300 warm air boxes.

[0040] Each of the heating boxes 300 is stacked vertically on the base 100.

[0041] The drive assembly 200 is also mounted on the base 100, and the drive end of the drive assembly 200 is connected to the heater box 300 to drive two adjacent heater boxes 300 to rotate in opposite directions.

[0042] In the aforementioned heater, at least two heater boxes 300 are stacked on the base 100. Under normal conditions, each heater box 300 provides hot air in the same direction, enough for a single person to warm up. When there are more people needing heating, the drive assembly 200 drives two adjacent heater boxes 300 to rotate in opposite directions, causing each heater box 300 to provide hot air in different directions, expanding the heating range until 180-degree air supply without dead zones is achieved, thus meeting the heating needs of multiple people.

[0043] Understandably, the heater box 300 can be rotated to any angle according to the user's needs, and the range of the warm air it blows out can be 90 degrees, 120 degrees, 150 degrees, etc. This embodiment does not limit this.

[0044] In some embodiments, the bottom heating box 300 is rotatably engaged with the base 100, and adjacent heating boxes 300 are rotatably engaged with each other.

[0045] In use, the lower heating box 300 provides rotational support to the upper heating box 300, while the bottom heating box 300 is supported by the base 100.

[0046] In some embodiments, the heater box 300 includes a first heater box 300a and a second heater box 300b. At least one set of the first heater box 300a and the second heater box 300b is provided, and the first heater box 300a is located below the second heater box 300b in the same set.

[0047] Understandably, when there are two or more sets of the first heating box 300a and the second heating box 300b, the sets of the first heating box 300a and the second heating box 300b are stacked vertically, and the first heating box 300a and the second heating box 300b are alternately distributed vertically.

[0048] Please combine Figure 3 Accordingly, the drive assembly 200 is located between the top end of the first heater box 300a and the bottom end of the second heater box 300b in the same group. The drive assembly 200 includes a first rotary drive end 210 and a second rotary drive end 220, with the first rotary drive end 210 connected to the first heater box 300a and the second rotary drive end 220 connected to the second heater box 300b.

[0049] The first rotary drive end 210 and the second rotary drive end 220 rotate in opposite directions, and their rotation angles are the same.

[0050] Driven by the first rotary drive end 210 and the second rotary drive end 220, the first heater box 300a and the second heater box 300b in the same group rotate in opposite directions, and the rotation angle is always the same.

[0051] Understandably, the drive assembly 200 is configured correspondingly to the first heater box 300a and the second heater box 300b, specifically meaning that each set of the first heater box 300a and the second heater box 300b is driven by one drive assembly 200. When there is one, two, or three sets of the first heater box 300a and the second heater box 300b, the drive assembly 200 is configured to have one, two, or three sets respectively.

[0052] Furthermore, the rotation angles of the first heater box 300a and the second heater box 300b in different groups can be different. Taking two groups of first heater boxes 300a and second heater boxes 300b as examples, the first heater box 300a and the second heater box 300b located in the lower layer rotate 30 degrees in opposite directions under the drive of the drive assembly 200, while the first heater box 300a and the second heater box 300b located in the upper layer rotate 60 degrees in opposite directions under the drive of another drive assembly 200. This embodiment does not limit this.

[0053] Please refer to the following: Figure 3 and Figure 4 Furthermore, the drive assembly 200 also includes a power component 230 and a transmission component 240. The power component 230 is connected to the first rotary drive end 210 and the second rotary drive end 220 respectively through the transmission component 240, so as to drive the first rotary drive end 210 and the second rotary drive end 220 to rotate.

[0054] Since the first rotary drive end 210 and the second rotary drive end 220 are driven by the same power component 230, it can be ensured that the first heater box 300a and the second heater box 300b rotate synchronously and at the same angle.

[0055] Optionally, the first rotary drive end 210 is a first gear ring, with its axis vertical and coinciding with the rotation axis of the first heater box 300a. Similarly, the second rotary drive end 220 is a second gear ring, with its axis vertical and coinciding with the rotation axis of the second heater box 300b. Furthermore, the axes of the first and second gear rings coincide.

[0056] Accordingly, the transmission component 240 is a transmission gear with its axis horizontal. The transmission gear is located between the first gear ring and the second gear ring, and meshes with the first gear ring and the second gear ring respectively.

[0057] When the power component 230 drives the transmission gear to rotate, the transmission gear drives the first gear ring and the second gear ring that mesh with it to rotate. Since the first gear ring and the second gear ring are located on both sides of the transmission gear, the linear velocity direction at the meshing point of the transmission gear and the first gear ring is opposite to the linear velocity direction at the meshing point of the transmission gear and the second gear ring, causing the first gear ring and the second gear ring to rotate in opposite directions, thereby driving the first heater box 300a and the second heater box 300b to rotate in opposite directions.

[0058] Understandably, the transmission gear has the same transmission ratio with the first gear ring and with the second gear ring, thereby ensuring that the first gear ring and the second gear ring rotate at the same speed, and thus ensuring that the first heater box 300a and the second heater box 300b rotate at the same angle.

[0059] Furthermore, the power component 230 is a servo motor, and the rotation shaft of the servo motor is connected to the transmission gear. Correspondingly, a controller is provided inside the base 100, and the controller is electrically connected to the servo motor.

[0060] In use, the user can input commands to the controller to start the servo motor, thereby driving the first heater box 300a and the second heater box 300b to rotate in opposite directions, and control the number of revolutions the servo motor's rotating shaft has made, thus precisely controlling the rotation angle of the first heater box 300a and the second heater box 300b.

[0061] In this embodiment, a set of first heating box 300a and second heating box 300b is provided, and the number of drive components 200 is one.

[0062] In addition, a column 110 is provided on the base 100. The column 110 is vertically arranged and located on one side of the first warm air box 300a, and the drive assembly 200 is located at the top of the column 110.

[0063] Please see Figure 3 Furthermore, the warm air box 300 is composed of a box body 310, a fan 320 and a heating element 330.

[0064] The housing 310 is equipped with an air inlet and an air outlet. The fan 320 and the heating element 330 are located inside the housing 310 and are arranged sequentially between the air inlet and the air outlet.

[0065] During use, the fan 320 causes the air inside the housing 310 to flow from the air inlet to the air outlet. As the air flows through the heating element 330, it is heated by the heating element 330, and the resulting hot air is finally discharged from the air outlet to provide warmth to the user.

[0066] Understandably, the controller is also electrically connected to the heating element 330, thereby enabling intelligent control and locking of the hot air temperature.

[0067] For example, the air inlet and air outlet are located on both sides of the housing 310, symmetrically distributed about the central area of ​​the housing 310. The fan 320 is adjacent to the air inlet, and the heating element 330 is adjacent to the air outlet.

[0068] It should be noted that during operation, the aforementioned heater can also be used with only the fan 320 turned on, without turning on the heating element 330. In this case, the heater can be used as an air cooler.

[0069] In some embodiments, the housing 310 is provided with an air inlet mesh 311 and an air outlet mesh 312. The air inlet mesh 311 covers the air inlet, and the air outlet mesh 312 covers the air outlet.

[0070] When in use, the air inlet net 311 and the air outlet net 312 can protect the fan 320 and the heating element 330 inside the housing 310 while ensuring ventilation, preventing foreign objects from entering the housing 310 and damaging the fan 320 and the heating element 330.

[0071] Furthermore, the first warm air box 300a has a groove 313 on the side of the box body 310 facing the column 110, and the air inlet is located at the bottom of the groove 313.

[0072] Under normal conditions, the first heater box 300a and the second heater box 300b provide hot air in the same direction, and the air inlet on the first heater box 300a is located on the side of the first heater box 300a facing the column 110, so as to minimize the obstruction of the hot air blown out by the column 110. At this time, a groove 313 is provided on the box body 310 of the first heater box 300a, and the air inlet is located at the bottom of the groove 313, which can prevent the column 110 from blocking the air inlet and ensure that the air flows smoothly within the box body 310 of the first heater box 300a.

[0073] In other embodiments, each heater box 300 may be driven by a different drive assembly 200, and the rotation angle of each heater box 300 is not limited, as long as two adjacent heater boxes 300 rotate in opposite directions.

[0074] In summary, under normal conditions, each of the heating chambers 300 in the aforementioned heater provides hot air in the same direction, enough for a single person to warm up. When there are more people needing heating, the drive assembly 200 drives two adjacent heating chambers 300 to rotate in opposite directions, causing each heating chamber 300 to provide hot air in different directions, expanding the heating range. It can provide comfortable hot air simultaneously with no dead angles up to 180 degrees, resulting in more even heat distribution in the space and thus meeting the heating needs of multiple people.

[0075] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0076] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0077] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
