Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more specifically, to a fireplace heater with multi-angle air supply. Background Technology

[0002] Fireplace heaters have a rich history and practical value. Fireplaces are the core heat source in the home, and people live and socialize around them. With the development of technology, modern fireplace heaters come in various forms, from traditional wood-burning fireplaces to electric fireplaces and gas fireplaces. Wood-burning fireplaces retain the original atmosphere, and the roaring flames bring visual and tactile warmth; electric fireplaces are convenient and safe, creating a cozy atmosphere through heating elements and simulated flames; today, fireplace heaters are not only heating tools, but also highlights of home decoration.

[0003] Existing fireplace heaters have many limitations. On the one hand, their structural design is poor, with fixed air outlet positions, often directing warm air in the wrong direction and making it difficult to accurately reach the user, resulting in insufficient warmth. On the other hand, although they have angle adjustment functions, the operation is cumbersome and complicated. Either the adjustment buttons are hard to find, or the adjustment process is sluggish. This prevents the warm air from spreading evenly in spaces with varying heights, resulting in uneven heating of the room. The warm air can only cover a small area, greatly reducing the overall heating effect. Therefore, improvements and optimizations are needed. Utility Model Content

[0006] As a preferred embodiment of this utility model, a heating mechanism is fixedly installed on the inner side of the shell, and a circular groove is opened on the back of the shell, with the circular groove arranged in a linear array covering the entire back of the shell.

[0008] As a preferred embodiment of the present invention, an adjusting torque block is fixedly installed at the top end of the first rotating rod, and the outer surface of the adjusting torque block is fixedly installed with protruding teeth in a circumferential array.

[0009] As a preferred embodiment of this utility model, the heating mechanism includes a heating wire fixedly installed on the rear side of the second exhaust bracket inside the housing, a gear knob rotatably installed on the right side of the housing and the heating wire connected to the gear knob via an electric wire, a power indicator light fixedly installed on the right side of the housing, a blower fixedly installed on the rear side of the heating wire inside the housing, and a protrusion fixedly installed on the outer surface of the gear knob.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes a first rotating rod to rotate a worm gear, which in turn rotates a meshing worm wheel. The worm wheel then rotates a second rotating rod, which in turn rotates multiple third bevel gears fixedly mounted on the outer surface of the second rotating rod. These third bevel gears then rotate multiple fourth bevel gears, which in turn rotate multiple fourth rotating rods. These fourth rotating rods then cause multiple second grid mechanisms to swing left and right. Compared to traditional devices, this device avoids the problem of warm air not effectively reaching the user, which can occur with traditional fixed grids. Furthermore, the adjustable height and orientation allow for even distribution of warm air at different heights, effectively improving the uniformity of heating in the room and covering a wider area.

[0014] 2. This utility model utilizes the magnetic attraction of both the first and second magnetic blocks, resulting in repulsion on both sides that causes the adsorption block to suspend inside the ventilation sphere. Air is then transported into the ventilation sphere through the air inlet filter. The attracted airflow causes the adsorption block to rotate. As the adsorption block rotates, fine particles in the air are sieved out on one side. The air is then transported into the housing through the ventilation holes, heated, and then transported outwards as warm air. Compared to traditional devices, this device, with its suspended adsorption block that rotates with the airflow, increases the contact area and time between the adsorption block and the air. When air flows past the adsorption block, its suspended and rotating state allows it to contact the adsorption block from multiple angles. Compared to traditional fixed adsorption devices, it can more effectively capture impurities in the air. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 7 As shown, this utility model provides a fireplace heater with multi-angle air supply, including a shell 1. A rectangular exhaust duct 2 is formed on the outer surface of the shell 1. A first exhaust bracket 3 is fixedly installed on the inner side of the rectangular exhaust duct 2. A first fixing block 4 is fixedly installed on the right side of the first exhaust bracket 3. A first grille mechanism is rotatably installed on the left inner wall of the first exhaust bracket 3. Multiple second rotating rods 7 are rotatably installed on the inner side of the first grille mechanism and extend to the inner side of the first fixing block 4. A first bevel gear 8 is fixedly installed at the end of each of the second rotating rods 7. A first rotating rod 9 is rotatably installed on the inner side of the shell 1 and extends to the inner side of the first fixing block 4. A second bevel gear 16 is fixedly sleeved on the outer surface of the first rotating rod 9 and meshes with the first bevel gear 8. A first bevel gear 8 is fixedly installed on the inner side of the shell 1. The second grid mechanism has a second fixed sleeve block 12 fixedly installed on its bottom side. Multiple fourth rotating round rods 15 are rotatably installed on the inner bottom of the second grid mechanism and extend to the inner side of the second fixed sleeve block 12. A fourth bevel gear 18 is fixedly installed on the bottom side of each of the fourth rotating round rods 15. A second rotating rod 19 is rotatably installed on the inner side of the second fixed sleeve block 12 and one end of the second rotating rod 19 is rotatably connected to the inner side of the second fixed sleeve block 12. A third bevel gear 17 is fixedly sleeved on the outer surface of the second rotating rod 19 and meshes with the fourth bevel gear 18. A worm gear 11 is fixedly connected to the bottom side of the first rotating rod 9. A worm wheel 20 is fixedly connected to the other end of the second rotating rod 19 and meshes with the worm gear 11. An adjusting torque block 10 is fixedly installed on the top end of the first rotating rod 9.

[0025] When the operator needs to adjust the airflow angle of the fireplace heater, they rotate the adjusting lever 10. This rotation of the lever 10 causes the first rotating rod 9 to rotate, which in turn causes multiple second bevel gears 16, which are fixedly sleeved on the outer surface of the first rotating rod 9, to rotate. The rotation of the second bevel gears 16 then causes multiple first bevel gears 8, which mesh with them, to rotate. These first bevel gears 8 then drive multiple second rotating rods 7 to rotate, which in turn cause multiple first grille mechanisms to swing up and down. Simultaneously, the rotation of the first rotating rod 9 drives the worm gear. When worm 11 starts to rotate, it will drive the worm wheel 20 that meshes with it to rotate. Then, the worm wheel 20 will drive the second rotating rod 19 to start rotating. When the second rotating rod 19 starts to rotate, it will drive multiple third bevel gears 17 that are fixedly sleeved on the outer surface of the second rotating rod 19 to rotate. When the multiple third bevel gears 17 rotate, they will drive multiple fourth bevel gears 18 that mesh with them to start rotating. Then, the multiple fourth bevel gears 18 will drive multiple fourth rotating round rods 15 to rotate. After that, the multiple fourth rotating round rods 15 will drive multiple second grille mechanisms to swing left and right, thereby realizing multi-angle air supply in the up, down, left and right directions.

[0026] Rotating the first rotating rod 9 will cause the worm gear 11 to rotate. When the worm gear 11 rotates, it will drive the worm wheel 20 to rotate. Then, the worm wheel 20 will drive the second rotating rod 19 to rotate. When the second rotating rod 19 rotates, it will drive multiple third bevel gears 17 fixedly sleeved on the outer surface of the second rotating rod 19 to rotate. When the multiple third bevel gears 17 rotate, they will drive multiple fourth bevel gears 18 to rotate. Then, the multiple fourth bevel gears 18 will drive multiple fourth rotating rods 15 to rotate. After that, the multiple fourth rotating rods 15 will drive multiple second grid mechanisms to swing left and right. Compared with traditional devices, this device avoids the situation where warm air cannot be effectively delivered to the user due to the traditional fixed grid. At the same time, due to the up, down, left and right adjustment, the warm air can be evenly distributed in the space at different heights, thereby effectively improving the uniformity of heating in the room and allowing the warm air to cover a wider area.

[0027] A heating mechanism is fixedly installed on the inner side of the shell 1. A circular groove 24 is provided on the back of the shell 1, and the circular groove 24 is arranged in a linear array to cover the entire back of the shell 1. A ventilation ball 25 is fixedly installed on the inner side of the circular groove 24. A first magnetic block 26 is fixedly installed on the upper inner wall of the ventilation ball 25. A second magnetic block 27 is fixedly installed on the lower inner wall of the ventilation ball 25. An adsorption block 28 is suspended between the first magnetic block 26 and the second magnetic block 27. A ventilation hole 29 is provided on the inner side of the ventilation ball 25 near the shell 1. An air inlet filter 30 is fixedly installed on the outer side of the ventilation ball 25 near the shell 1.

[0028] When the heating mechanism is activated, the outside air will be drawn into the inside of the housing 1. The air first passes through the air inlet filter 30 to filter out large particles. Then, since both the first magnetic block 26 and the second magnetic block 27 have magnetic attraction, the repulsive force on both sides will cause the adsorption block 28 to suspend inside the ventilation sphere 25. At this time, the air is transported into the ventilation sphere 25 through the air inlet filter 30. As the air is attracted, the flow rate will drive the adsorption block 28 to rotate. When the adsorption block 28 rotates, the fine particles in the air will be screened out on one side. Then the air will be transported into the inside of the housing 1 through the ventilation hole 29, heated into warm air, and transported outward.

[0029] Since both the first magnetic block 26 and the second magnetic block 27 contain magnetic attraction, the repulsive force on both sides will cause the adsorption block 28 to suspend inside the ventilation sphere 25. At this time, air is transported into the ventilation sphere 25 through the air inlet filter 30. As the air is attracted, the flow rate will drive the adsorption block 28 to rotate. When the adsorption block 28 rotates, fine particles in the air will be screened out on one side. Then the air will be transported into the inner side of the housing 1 through the ventilation hole 29, heated into warm air and transported outward. Compared with traditional devices, this device has an adsorption block that is suspended and can rotate with the air flow, which can increase the contact area and contact time between the adsorption block and the air. When the air flows through the adsorption block, because it is in a suspended and rotating state, the air can contact the adsorption block from multiple angles. Compared with traditional fixed adsorption devices, it can capture impurities in the air more effectively.

[0030] The first grille mechanism includes a plurality of first rotating rods 5 rotatably mounted on the left inner wall of the first exhaust support 3, a plurality of second rotating rods 7 rotatably mounted on the inner side of the first exhaust support 3 and extending to the inner side of the first fixed sleeve block 4, and a first grille 6 fixedly mounted between the first rotating rods 5 and the second rotating rods 7. The second grille mechanism includes a second exhaust support 13 fixedly mounted on the inner side of the housing 1 and fixedly connected to the first exhaust support 3, a plurality of third rotating rods 14 rotatably mounted on the upper inner wall of the second exhaust support 13, and a second grille 21 fixedly mounted between the third rotating rods 14 and the fourth rotating rods 15.

[0031] Multiple first bevel gears 8 will drive multiple second rotating rods 7 to rotate. Then, multiple second rotating rods 7 will drive multiple first grilles 6 to swing up and down. At this time, the first rotating rod 5 will also rotate. Then, multiple fourth rotating rods 15 will drive multiple second grilles 21 to swing left and right. At this time, the third rotating rod 14 will also rotate, thereby realizing multi-angle air supply in the up, down, left and right directions.

[0032] The top end of the first rotating rod 9 is fixedly equipped with an adjusting torque block 10, and the outer surface of the adjusting torque block 10 is fixedly equipped with protruding teeth in a circumferential array.

[0033] By adjusting the outer surface of the torsion block 10, which is fixedly installed with protruding teeth in a circumferential array, the friction during rotation can be effectively increased, thus increasing the perception of the torsion.

[0034] The heating mechanism includes a heating wire 22 fixedly installed on the rear side of the second exhaust bracket 13 inside the housing 1, a gear knob 32 rotatably installed on the right side of the housing 1 and the heating wire 22 is connected to the gear knob 32 by a wire, a power indicator light 33 fixedly installed on the right side of the housing 1, a blower 23 fixedly installed on the rear side of the heating wire 22 inside the housing 1, and a protrusion fixedly installed on the outer surface of the gear knob 32.

[0035] Turning the speed knob 32 will change the temperature of the heating wire 22, and then the blower 23 will blow the air outward. When the air passes through the heating wire 22, it will be heated, thereby achieving a warming effect. The speed knob 32 is equipped with a protrusion, which allows for more precise adjustment when adjusting the temperature.

[0036] The top of the housing 1 is fixedly equipped with a handrail 31, and the handrail 31 is arc-shaped.

[0037] The curved shape of the handrail 31 allows staff to move the entire device flexibly, increasing its applicability to different scenarios.

[0038] The bottom side of the housing 1 is fixedly equipped with a foot pedal 34, and the foot pedal 34 is fixedly installed around the bottom side of the housing 1.

[0039] By fixing the foot pedals 34 to the bottom of the housing 1, the stability of the entire device can be effectively increased, avoiding tipping and safety risks.

[0040] Working principle and usage process of this utility model:

[0041] When the operator needs to adjust the airflow angle of the fireplace heater, they rotate the adjusting lever 10. This rotation of the lever 10 causes the first rotating rod 9 to rotate, which in turn causes multiple second bevel gears 16, which are fixedly sleeved on the outer surface of the first rotating rod 9, to rotate. The rotation of the second bevel gears 16 then causes multiple first bevel gears 8, which mesh with them, to rotate. These first bevel gears 8 then drive multiple second rotating rods 7 to rotate, which in turn cause multiple first grille mechanisms to swing up and down. Simultaneously, the rotation of the first rotating rod 9 drives the worm gear. When worm 11 starts to rotate, it will drive the worm wheel 20 that meshes with it to rotate. Then, the worm wheel 20 will drive the second rotating rod 19 to start rotating. When the second rotating rod 19 starts to rotate, it will drive multiple third bevel gears 17 that are fixedly sleeved on the outer surface of the second rotating rod 19 to rotate. When the multiple third bevel gears 17 rotate, they will drive multiple fourth bevel gears 18 that mesh with them to start rotating. Then, the multiple fourth bevel gears 18 will drive multiple fourth rotating round rods 15 to rotate. After that, the multiple fourth rotating round rods 15 will drive multiple second grille mechanisms to swing left and right, thereby realizing multi-angle air supply in the up, down, left and right directions.

[0042] When the heating mechanism is activated, the outside air will be drawn into the inside of the housing 1. The air first passes through the air inlet filter 30 to filter out large particles. Then, since both the first magnetic block 26 and the second magnetic block 27 have magnetic attraction, the repulsive force on both sides will cause the adsorption block 28 to suspend inside the ventilation sphere 25. At this time, the air is transported into the ventilation sphere 25 through the air inlet filter 30. As the air is attracted, the flow rate will drive the adsorption block 28 to rotate. When the adsorption block 28 rotates, the fine particles in the air will be screened out on one side. Then the air will be transported into the inside of the housing 1 through the ventilation hole 29, heated into warm air, and transported outward.
