Description

Technical Field

[0001] This utility model relates to the technical field of heater air guiding, specifically an adjustable wide-angle heater air guiding component. Background Technology

[0002] A heater is a household appliance that converts electrical or chemical energy into heat energy using electricity, gas, or other energy sources, and provides auxiliary heating to a specific space or area through radiation, convection, or forced ventilation. It is widely used in homes, offices, and other places to raise the temperature of a local or overall environment.

[0003] The air guide component is a key structure inside some heaters. It usually consists of an air duct, an air outlet grille, and a drive motor. Its main function is to guide and direct the flow path and direction of hot air. Through automatic or manual oscillation of the blades, this component can achieve wide-angle air delivery to expand the heating range and avoid heat concentration. At the same time, it can also deliver air precisely as needed, improving thermal efficiency and enhancing user comfort.

[0004] The air guide components of existing heaters have technical limitations: the angle adjustment stroke of their air guide plates is limited by the structural design, and the maximum adjustment angle can only be kept perpendicular to the air outlet. This results in the air delivery direction being limited to a single dimension directly in front, making it impossible to achieve multi-directional diffusion of hot air. This defect directly causes a narrow air delivery range, and the hot air can only concentrate on covering a local area directly in front of the air outlet, while the sides and diagonal spaces are difficult to reach with warm air, thus causing uneven indoor temperature distribution. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable wide-angle heater air guide assembly to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An adjustable wide-angle heater air guide assembly includes a housing, two first air guide plates rotatably mounted inside the housing at the middle position, and two second air guide plates rotatably mounted inside the housing at both sides. A knob is located at one end of the housing, and a connecting rod is connected to one end of the knob. A transmission mechanism is slidably mounted on the connecting rod. A locking mechanism is provided at one end of the knob. One end of the transmission mechanism is drivenly connected to a bidirectional moving mechanism and a sliding plate connected to the bidirectional moving mechanism. A meshing transmission assembly is provided on the sliding plate, and the meshing transmission assembly is drivenly engaged with the first and second air guide plates.

[0007] The adjustable wide-angle heater air guide assembly as described above: the transmission mechanism includes a sleeve slidably mounted on one end of the connecting rod and a first spring disposed inside the sleeve, the first spring abutting against the connecting rod, and the sleeve being rotatably mounted inside the housing.

[0008] The adjustable wide-angle heater air guide assembly as described above: the locking mechanism includes multiple inserts arranged circumferentially on the back of the knob, the inserts being plugged into sockets fixed on the housing.

[0009] The adjustable wide-angle heater air guide assembly as described above: the transmission mechanism includes a bevel gear set connected to one end of the sleeve, a bidirectional lead screw meshing on the bevel gear set, and the bidirectional lead screw being rotatably installed inside the housing.

[0010] The adjustable wide-angle heater air guide assembly described above: the bidirectional moving mechanism includes two connecting arms threaded onto the bidirectional lead screw and a sliding plate connected to the connecting arms, with a sliding groove provided at one end of the sliding plate.

[0011] The adjustable wide-angle heater air guide assembly described above: a sliding toothed plate and a second spring connected to one end of the sliding toothed plate are slidably mounted on the sliding groove of the sliding plate, and the second spring abuts against the sliding groove.

[0012] As described above, the adjustable wide-angle heater air guide assembly includes a fixed toothed plate connected to one end of the sliding plate, and transmission teeth connected to one end of both the first and second air guide plates. The sliding toothed plate meshes with the transmission teeth fixed to one end of the first air guide plate, and the fixed toothed plate meshes with the transmission teeth fixed to one end of the second air guide plate. Four limiting brackets for limiting the rotation angle of the first and second air guide plates are connected inside the housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are: By ingeniously increasing the turning range of the outermost air guide plate, it can deflect to the left and right sides at a greater angle, thereby accurately diverting the concentrated forward airflow to the sides at an angle. It can deflect the airflow at a large angle to achieve diversion and guidance, which can not only accurately guide the hot airflow to the front and side areas, but also significantly widen the air supply angle and heat diffusion coverage area, allowing the heating range to extend from the front of the air outlet to a wider space on both sides, thus breaking through the limitation of traditional air guide plates that can only be adjusted to an angle perpendicular to the air outlet.

[0014] This invention can effectively improve the problems of concentrated heat and local overheating in the traditional direct-blowing mode, promote the uniform distribution of warm air in the room, reduce the temperature difference and heat loss in the space, and improve the comfort and temperature balance of heating multiple areas at the same time.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Please see Figures 1-14 As an embodiment of this utility model, the adjustable wide-angle heater air guide assembly includes a housing 1, two first air guide plates 2 rotatably mounted inside the middle section of the housing 1, and two second air guide plates 3 rotatably mounted inside the housing 1 on both sides. A knob 4 is located at one end of the housing 1, and a connecting rod 5 is connected to one end of the knob 4. A transmission mechanism is slidably mounted on the connecting rod 5. A locking mechanism is provided at one end of the knob 4. A bidirectional moving mechanism and a sliding plate 12 connected to the bidirectional moving mechanism are connected to one end of the transmission mechanism. A meshing transmission assembly is provided on the sliding plate 12. The meshing transmission assembly is in a transmission cooperation with the first air guide plate 2 and the second air guide plate 3.

[0032] In this embodiment, by rotating the knob 4, the knob 4, through the coordinated action of the bidirectional moving mechanism, the meshing transmission component, and the transmission mechanism, can drive the two first air guide plates 2 and the second air guide plates 3 inside the casing 1 to deflect. The two outermost second air guide plates 3 can achieve a larger deflection angle, thereby accurately diverting the concentrated forward airflow to the sides at an angle. It can deflect the airflow at a large angle to achieve diversion and guidance, which can not only accurately guide the hot airflow to the oblique front and side areas, but also significantly widen the air supply angle and heat diffusion coverage area, allowing the heating range to extend from the front of the air outlet to a wider space on both sides, thus breaking through the limitation of traditional air guide plates that can only be adjusted to an angle perpendicular to the air outlet.

[0033] As a further embodiment of this utility model, the transmission mechanism includes a sleeve 6 slidably mounted on one end of the connecting rod 5 and a first spring 7 disposed inside the sleeve 6. The first spring 7 abuts against the connecting rod 5, and the sleeve 6 is rotatably mounted inside the housing 1.

[0034] In this embodiment, the knob 4 is fixed to the connecting rod 5, the connecting rod 5 slides inside the sleeve 6, and the first spring 7 abuts against the connecting rod 5 to elastically reset the connecting rod 5.

[0035] As a further embodiment of this utility model, the locking mechanism includes a plurality of insert rods circumferentially arranged on the back of the knob 4, and the insert rods are inserted into a socket 8 fixed on the housing 1.

[0036] In this embodiment, multiple insert rods are arranged circumferentially on the back of the knob 4, and a slot for cooperating with the insert rods is provided on the socket 8 on one side of the back of the knob 4.

[0037] As a further embodiment of this utility model, the transmission mechanism includes a bevel gear set 9 connected to one end of the sleeve 6, and a bidirectional lead screw 10 meshing on the bevel gear set 9, the bidirectional lead screw 10 being rotatably mounted inside the housing 1.

[0038] In this embodiment, the sleeve 6 is connected to the bevel gear set 9, and the bevel gear set 9 is fixedly sleeved on the middle section of the bidirectional lead screw 10, with the threads at both ends of the bidirectional lead screw 10 having opposite directions.

[0039] As a further embodiment of this utility model, the bidirectional moving mechanism includes two connecting arms 11 threaded onto the bidirectional lead screw 10 and a sliding plate 12 connected to the connecting arms 11, with a sliding groove provided at one end of the sliding plate 12.

[0040] In this embodiment, when the bidirectional lead screw 10 rotates, it drives the two connecting arms 11 to move towards each other, thereby driving the two sliding plates 12 to move in different directions.

[0041] As a further embodiment of this utility model, a sliding toothed plate 14 and a second spring 15 connected to one end of the sliding toothed plate 14 are slidably mounted on the sliding groove of the sliding plate 12, and the second spring 15 abuts against the sliding groove.

[0042] In this embodiment, a sliding toothed plate 14 is slidably mounted on one end of the sliding plate 12, and the second spring 15 elastically resets the sliding toothed plate 14.

[0043] As a further embodiment of this utility model, the meshing transmission assembly includes a fixed toothed plate 13 connected to one end of the sliding plate 12, and transmission teeth 16 connected to one end of both the first air guide plate 2 and the second air guide plate 3. The sliding toothed plate 14 meshes with the transmission teeth 16 fixed to one end of the first air guide plate 2, and the fixed toothed plate 13 meshes with the transmission teeth 16 fixed to one end of the second air guide plate 3. Four limiting frames 17 for limiting the rotation angle of the first air guide plate 2 and the second air guide plate 3 are connected inside the housing 1.

[0044] In this embodiment, during use, the knob 4 is first pulled upwards, causing the knob 4 to move the connecting rod 5 upwards and compress the first spring 7. During this process, multiple inserts on the back of the knob 4 will disengage from the socket 8. At this time, the knob 4 can be rotated, which will cause the entire sleeve 6 to rotate. Then, the bevel gear set 9 drives the bidirectional lead screw 10 to rotate, causing the two connecting arms 11 to move towards each other and the two sliding plates 12 to move towards each other. At this time, the fixed toothed plate 13 and the sliding toothed plate 14 on the sliding plate 12 will mesh with the transmission teeth 16 on one side of the first air guide plate 2 and the second air guide plate 3, respectively, and drive the first air guide plate 2 and the second air guide plate 3 to rotate. At the same time, a limit is set at one end of the first air guide plate 2 and the second air guide plate 3. The positioning frame 17 limits its maximum rotation angle. The maximum rotation angle of the positioning frame 17 located on one side of the first air guide plate 2 is smaller than that of the positioning frame 17 on the side of the second air guide plate 3. This allows the second air guide plate 3 to accept a larger rotation angle. When the sliding plate 12 moves, the sliding toothed plate 14 will first drive the first air guide plate 2 to reach the maximum deflection angle. At this time, when the sliding plate 12 continues to move, the sliding toothed plate 14 will retract into the groove of the sliding plate 12 and compress the second spring 15. The continued movement of the sliding plate 12 will drive the fixed toothed plate 13, thereby allowing the second air guide plates 3 on both sides to obtain a larger rotation angle, so as to accurately divert the concentrated forward airflow to both sides at an angle. It can deflect significantly at an angle to achieve diversion and guidance.

[0045] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
