[0001] The utility model relates to the technical field of electrical appliances, in particular to a swing-blade air guide device and a bathroom heater containing the same. Background Art

[0002] Yuba heaters, a type of air blower, are a must-have bathroom heating device for many families. They provide heating, lighting, ventilation, and other functions to ensure comfortable bathing in cold weather. The Yuba heater's air outlet is equipped with swinging blades, which evenly distribute warm or cool air to every corner of the bathroom, enhancing the effect. The swinging blade design allows the Yuba heater to deliver air over a wider range and provide more uniform wind force.

[0003] With the continuous development of large honeycomb panels in the ceiling industry, the design of the accompanying air-heated bathroom heaters has gradually become narrower and more linear to accommodate these large honeycomb ceiling panels. This results in the heater's air outlet and swing blades being narrower and longer than those of ordinary heaters. The swing blades of ordinary heaters are usually made of plastic, which has weak structural strength. The longer the blades, the more difficult it is to form during injection molding and the more likely they are to twist and deform, affecting assembly and use. Furthermore, the swing blades are installed at the warm air outlet and are prone to aging in high-temperature environments for extended periods, shortening their service life. Utility Model Content

[0031] The embodiments of the present application provide a swing blade air guide device and a bathroom heater containing the same to solve the technical problem in the prior art that the swing blades of bathroom heaters are weak in strength and prone to deformation and aging, thereby affecting their service life.

[0032] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0033] like Figure 1As shown, one or more embodiments of the present application provide a swing blade air guide device, which is used at the air outlet of a hair dryer, such as the air outlet of an air-heated bathroom heater, to guide the air so that the air supply range is wider and the wind force is more uniform.

[0034] like Figures 1 to 4 As shown, the swing vane air guide device includes an air outlet plate 10, and an air outlet 11 is formed in the middle of the air outlet plate 10. A swing vane plate 20 is rotatably provided in the air outlet 11. When the swing vane plate 20 rotates to the front side parallel to the front side of the air outlet plate 10 (i.e., parallel to the air outlet 11), the swing vane plate 20 seals the air outlet 11 and is in a closed state. Figure 4 When the vane 20 is rotated to tilt within the air outlet 11, the gap between the vane 20 and the air outlet 11 allows air to pass through, thereby discharging air, and is in the air outlet state, as shown Figure 2 Therefore, by adjusting the inclination angle of the swing blade 20, the gas can be guided to different directions.

[0035] The material of the swing blade 20 is metal, such as aluminum alloy, magnesium alloy, titanium alloy, etc., which has high strength. Even if it is made into a slender structure, it is not easy to twist and deform. Even when used in a high-temperature environment for a long time, it is not easy to deform and age. It is more durable, has a longer service life, has a better flame retardant effect, and improves safety performance.

[0036] like Figures 1 to 7 As shown, the swing blade 20 gradually becomes smaller from the front to the back to form a quadrangular prism, wherein the largest front can close the air outlet 11, and the side of the swing blade 20 is a slope, which can reduce obstruction and facilitate smoother flow of wind.

[0037] Furthermore, the interior of the swing blade 20 is hollow to form an inner cavity to reduce its own weight, which can reduce both material cost and rollover resistance.

[0038] Since the material of the swing blade 20 is metal, the original plastic material swing blade and the air outlet connection structure is no longer applicable. In one embodiment of the present application, the left and right ends of the swing blade 20 are respectively rotatably arranged in the air outlet 11 through the swing blade bracket 30. Figures 1 to 8 shown.

[0039] The air outlet plate 10 is in the shape of a rectangular parallelepiped, and a rotation hole 13 is provided on the inner wall of the left and right ends of the air outlet 11. The above-mentioned swing blade bracket 30 includes a rotating shaft 31 rotatably arranged in the rotating hole 13, and a latch 32 for connecting to the swing blade plate 20. One end of the rotating shaft 31 is fixedly connected to the latch 32, and the other end of at least one rotating shaft 31 is connected to a motor 40. The motor shaft of the motor 40 is fixedly connected to the rotating shaft 31, thereby driving the swing blade bracket 30 to rotate, and then driving the swing blade plate 20 to rotate, as shown in FIG. Figures 1 to 8 shown.

[0040] The latch 32 is snap-fitted to the swing plate 20. Openings are formed on the left and right ends of the swing plate 20 for inserting the latch 32 into the inner cavity of the swing plate 20. A resettable spring catch 34 is provided on the back of the latch 32. A corresponding rectangular hole 25 is provided on the back of the swing plate 20. As the latch 32 is inserted into the trapezoidal hollow cavity of the swing plate 20, the spring catch 34 is compressed and ejected from the hole 25, thereby preventing the swing bracket 30 from moving out of the swing plate 20. The connection between the swing bracket 30 and the swing plate 20 via the latch and spring catch 34 simplifies the installation process, reduces the use of screws, improves production efficiency, and reduces costs compared to traditional screw-fixing solutions.

[0041] The cross-sectional shape of the latch 32 can be adapted to the cross-sectional shape of the inner cavity of the swing vane 20 and be a trapezoid, so as to reduce the shaking of the latch 32 after being inserted into the inner cavity of the swing vane 20 .

[0042] In addition, if Figure 8 As shown, the front end surface 342 of the spring buckle 34 (the side that first contacts the hole 25 when inserted into the hole 25) is an inclined surface, and the rear end surface 341 (the side facing the rotating shaft 31) is a vertical surface. In this way, the spring buckle 34 is easy to insert into the hole 25 and is not easy to fall out of the hole 25.

[0043] like Figure 1 、 5 As shown in Figures 1 and 7, the left and right ends of the back surface of the swing vane 20 are recessed toward the middle of itself to form a positioning groove 24, the opening is located in the positioning groove 24, and a positioning plate 33 is formed on the latch 32. In this way, when the spring buckle 34 is inserted into the hole 25, the positioning plate 33 is engaged in the positioning groove 24, and the spring buckle 34 limits the latch 32 from the left and right ends respectively, thereby strengthening the connection strength between the swing vane bracket 30 and the swing vane 20. At the same time, the positioning groove 24 is provided on the back surface of the swing vane 20, so that the positioning plate 33 can be hidden behind the front surface of the swing vane 20, without affecting the sealing of the air outlet 11 of the swing vane 20 or the appearance of the swing vane 20.

[0044] Further, such as Figure 8 As shown, a spring piece 36 is cut out from the back of the pendulum plate 20, one end of the spring piece 36 is connected to the back of the pendulum plate 20, and there is a gap 35 between the other edge and the back of the pendulum plate 20, so that it has a certain elasticity. The spring buckle 34 is set on the spring piece 36, so that when the pin 32 is inserted into the trapezoidal hollow cavity of the pendulum plate 20, the spring buckle 34 follows the spring piece 36 and has a certain elasticity.

[0045] like Figure 1 、 3As shown in Figure 9, the swing blade air guide device also includes a stop mechanism for limiting the rotation angle of the rotating shaft 31, and the stop mechanism includes a stop baffle 311 radially arranged on the outer surface of the rotating shaft 31, and a stop rib 12 correspondingly arranged on the inner wall of the air outlet 11, and the stop rib 12 is located on the rotation trajectory of the corresponding stop baffle 311. When the rotating shaft 31 rotates until the stop baffle 311 abuts against the stop rib 12 and is restricted from rotating by the stop rib 12, the swing blade 20 is parallel to the air outlet 11, and the rotating shaft 31 of the swing blade 20 stops rotating to seal the air outlet 11.

[0046] By designing the stop baffle 311 and the stop rib 12 on the rotating shaft 31 of the swing blade bracket 30, the angle range and position of the rotation of the swing blade air guide device can be limited, so that the swing blade air guide device can only rotate within the set position angle range without interfering with other components, thereby improving the stability and safety of the swing blade air guide device during operation.

[0047] A pressure sensor is provided at the position where the stop baffle 311 is used to abut the stop rib 12 (of course, the pressure sensor can also be provided on the stop rib 12). When the rotating shaft 31 rotates until the stop baffle 311 abuts against the stop rib 12, the stop baffle 311 will be squeezed and the pressure detected by the pressure sensor will increase.

[0048] The swing blade air guide device includes a controller. For example, when the swing blade air guide device is used for a bathroom heater, the controller can be the controller of the bathroom heater. The signal input end of the controller is connected to the pressure sensor for receiving the pressure signal obtained by the pressure sensor. The signal output end of the controller outputs a control signal, and the control signal is used to control the motor 40, thereby controlling the motor 40 based on the pressure signal.

[0049] A pressure threshold is pre-stored in the controller. When the controller recognizes that the pressure obtained by the pressure sensor exceeds the threshold, it determines that the shaft 31 rotates until the stop baffle 311 contacts the stop rib 12 and controls the motor 40 to stop rotating. Otherwise, the drive motor 40 continues to rotate.
