Description

Technical Field

[0001] This utility model relates to the technical field of bathroom heaters, and in particular to a mask assembly and a bathroom heater. Background Technology

[0002] In existing bathroom heater products, the drive structure for opening and closing the light panel is usually located inside the cover. This drive structure needs to pass through the cover housing and connect to the movable light panel to realize the opening and closing action of the light panel relative to the cover.

[0003] However, to accommodate the movement of the drive components, a large window or passage must be opened in the mask structure. This large window directly leads to two key problems: First, the overall sealing of the mask is reduced, and the ventilation volume is significantly increased, which seriously affects the aerodynamic performance of the internal air duct of the bathroom heater; Second, the large window inevitably weakens the structural integrity of the mask itself, resulting in insufficient mechanical strength. Under long-term use or external force, it is prone to deformation, breakage and other failure risks, affecting product safety and service life. Utility Model Content

[0004] Therefore, it is necessary to provide a mask assembly and a bathroom heater that requires a relatively small window to accommodate the passage of the driving components, in order to address the current problem of large windows being required in the current bathroom heater masks.

[0005] This application first provides a face mask assembly, including a fixed plate, a movable plate, a transmission assembly, and a driving component. The movable plate is movably connected to the fixed plate, and the fixed plate has a through hole.

[0006] The transmission assembly includes a first transmission member and a second transmission member rotatably connected to the fixed plate. The movement paths of the first transmission member and the second transmission member pass through the through hole, and both are also connected to the movable plate.

[0007] The driving component is poweredly connected to the first transmission component to drive the first transmission component to rotate;

[0008] The movable plate has an open state and a closed state. When the movable plate is in the open state, the distance between the movable plate and the fixed plate is greater than the distance when the plate is in the closed state.

[0009] In one embodiment, one end of the first transmission member and the second transmission member are hinged to the fixed plate, and the other end is hinged to the movable plate to form four hinge points connected in a parallelogram.

[0010] In one embodiment, at least one of the first transmission member and the second transmission member includes a connecting segment and an arc segment. The connecting segment is hinged to the fixed plate, and one end of the arc segment is fixed to the connecting segment, while the other end passes through the through hole and is hinged to the movable plate.

[0011] In one embodiment, the output shaft of the drive member is provided with a drive gear, and the first transmission member meshes with the drive gear.

[0012] In one embodiment, the outer contour of the first transmission member is fan-shaped, and the outer edge of the fan-shaped member meshes with the drive gear.

[0013] In one embodiment, the central angle of the sector of the first transmission member ranges from 90° to 180°.

[0014] In one embodiment, at least one of the first transmission member and the second transmission member is provided with a weight reduction groove.

[0015] In one embodiment, a mounting base is also fixed to the side of the fixing plate where the driving member is located, and the mounting base is arranged around the through hole;

[0016] The mounting base is provided with a first hinge seat at intervals.

[0017] In one embodiment, the movable plate is fixed with a second hinge seat that is respectively hinged to the first transmission member and the second transmission member.

[0018] In one embodiment, the fixed plate is provided with two sets of the transmission components, and the drive member is located between the two sets of the transmission components.

[0019] This application also provides a bathroom heater, including a bathroom heater body and the above-mentioned mask assembly, wherein the fixing plate is a mask fixed to the bathroom heater body, and the movable plate is a light panel.

[0020] The aforementioned mask assembly uses the first and second transmission components to drive the movable plate through the through hole to achieve opening and closing, which significantly reduces the requirement for the through hole area. On the one hand, it can improve the overall sealing performance of the fixed plate, which is beneficial to improving the aerodynamic performance of the internal air duct. On the other hand, it can preserve the material continuity of the fixed plate to the greatest extent, which can significantly improve the overall mechanical strength and rigidity of this application, thereby enhancing the reliability and service life of the product.

[0033] Please combine Figure 1 , Figure 2 as well as Figure 3 As shown, this application first provides a mask assembly, including a fixed plate 10, a movable plate 20, a transmission assembly 30, and a driving member 40. The movable plate 20 is movably connected to the fixed plate 10, and the fixed plate 10 has a through hole 111. The transmission assembly 30 includes a first transmission member 31 and a second transmission member 32 rotatably connected to the fixed plate 10. The movement paths of the first transmission member 31 and the second transmission member 32 pass through the through hole 111, and both are also connected to the movable plate 20. The driving member 40 is poweredly connected to the first transmission member 31 to drive the first transmission member 31 to rotate. The movable plate 20 has an open state and a closed state. When the movable plate 20 is open, the distance between the movable plate 20 and the fixed plate 10 is greater than the distance when the movable plate 20 is closed.

[0034] In this application, the movable plate 20 is opened and closed by the first transmission component 31 and the second transmission component 32 passing through the through hole 111, which significantly reduces the area requirement of the through hole 111. On the one hand, it can improve the overall sealing performance of the fixed plate 10, which is conducive to improving the aerodynamic performance of the internal air duct. On the other hand, it can preserve the material continuity of the fixed plate 10 to the greatest extent, which can significantly improve the overall mechanical strength and rigidity of this application, thereby enhancing the reliability and service life of the product.

[0035] In some embodiments, one end of the first transmission member 31 and the second transmission member 32 are hinged to the fixed plate 10, and the other end is hinged to the movable plate 20, so as to form four hinge points with a parallelogram-shaped connection.

[0036] By forming a parallelogram structure through four-point hinges, when the driving member 40 drives the first transmission member 31 to rotate around its hinge point on the fixed plate 10, the constraint of the four-bar linkage can precisely ensure that the movement of the movable plate 20 relative to the fixed plate 10 always follows the circumferential trajectory of the hinge point between the first transmission member 31 and the movable plate 20. This allows the arc segment 30b to minimize the size requirement of the through hole 111 while meeting the travel requirements of the transmission component 30.

[0037] Of course, in some other embodiments, the first transmission member 31 and the second transmission member 32 can also be connected to the fixed plate 10 by other common rotational connection methods, such as bearing connection, as long as the first transmission member 31 and the second transmission member 32 can rotate relative to the fixed plate 10.

[0038] In some embodiments, at least one of the first transmission member 31 and the second transmission member 32 includes a connecting segment 30a and an arc segment 30b. The connecting segment 30a is hinged to the fixed plate 10, and one end of the arc segment 30b is fixed to the connecting segment 30a, while the other end passes through the through hole 111 and is hinged to the movable plate 20.

[0039] In other words, at least one transmission component includes an arc segment 30b. Specifically, the center of the arc segment 30b is the hinge point between the transmission component and the fixed plate 10. During the movement of the arc segment 30b, the area passing through the through hole 111 remains constant. Therefore, the through hole 111 only needs to be able to allow the arc segment 30b to pass through, which further reduces the requirement for the opening area of ​​the through hole 111.

[0040] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the output shaft 41 of the drive member 40 extends along the Y-axis direction, and a drive gear 42 is fixed on the output shaft 41 between the first transmission member 31 and the second transmission member 32 along the X-axis direction, and the first transmission member 31 meshes with the drive gear 42.

[0041] The direct transmission via gear meshing enables efficient and stable power transmission, which helps improve the stability of the movable plate 20. Furthermore, the arrangement of the drive component 40 and the transmission assembly 30 along the XY plane effectively reduces the space occupied by the mask assembly along the Z-axis, thereby improving structural compactness and reducing thickness.

[0042] Of course, in some other embodiments, the drive member 40 may also adopt other commonly used transmission structures to power the transmission component 30, and the drive member 40 and the transmission component 30 may also adopt other layout methods, as long as the drive member 40 can drive the first transmission member 31 to rotate around the hinge point between itself and the fixed plate 10. This application will not give examples of each one here.

[0043] Please combine Figure 2 , Figure 3 as well as Figure 4 As shown, in some embodiments, the outer contour of the first transmission member 31 is fan-shaped, the center of the fan shape is hinged to the fixed plate 10, and the outer edge of the fan shape meshes with the drive gear 42.

[0044] The movable plate 20 has an open state and a closed state. In the closed state, the end of the outer edge of the sector gear near the movable plate 20 meshes with the drive gear 42. In the open state, the other end of the outer edge of the sector gear meshes with the drive gear 42.

[0045] It is not difficult to understand that the movement trajectory of the movable plate 20 can be regarded as the movement trajectory of the hinge point between the first transmission member 31 and the movable plate 20 (i.e., the end of the sector gear with its outer edge surface close to the movable plate 20). Therefore, as long as the arc segment 30b corresponds to the outer edge surface of the sector gear, the movement trajectory of the arc segment 30b can be ensured to correspond to the outer edge surface of the sector gear, thereby further reducing the required size of the through hole 111.

[0046] In addition, by restricting the outer edge of the sector gear to mesh with the drive gear 42 near the movable plate 20 in the closed state, when the movable plate 20 is opened from the closed state, the displacement of the movable plate 20 along the Z-axis is more obvious in the start-up phase, so that a gap can be formed between the fixed plate 10 and the movable plate 20 immediately and airflow can be realized, thereby improving the initial air outlet efficiency.

[0047] In some embodiments, the central angle of the sector of the first transmission member 31 ranges from 90° to 180°.

[0048] The central angle range of the sector of the first transmission component 31 corresponds to the opening stroke of the movable plate 20. If the angle is too small, it will affect the limit opening of the movable plate 20 and affect normal use. Conversely, if the angle is too large, the volume of the first transmission component 31 and the second transmission component 32 will be too large and will occupy space in the Z-axis direction.

[0049] Preferably, the central angle of the sector of the first transmission component 31 is 135°. By limiting the engagement of the two ends of the outer edge of the sector gear with the drive gear 42 in the open and closed states, and in conjunction with the design of the central angle of the sector of the first transmission component 31 and the initial deflection angle, the moving speed of the movable plate 20 in the vertical and horizontal directions during the opening and closing process can be controlled. Taking a central angle of 135° for the sector of the first transmission component 31 as an example:

[0050] For ease of description, the vertical displacement of the movable plate 20 when the first transmission component 31 rotates by the same degree is defined as the vertical displacement, and the horizontal displacement is defined as the horizontal displacement.

[0051] When the movable plate 20 is initially opened (starting from the first transmission component 31 rotating 0°), the vertical displacement is the largest and the horizontal displacement is the smallest. As the first transmission component 31 rotates, the vertical displacement gradually decreases and the horizontal displacement gradually increases. When the first transmission component 31 rotates to 45°, the vertical displacement and horizontal displacement are the same. When the first transmission component 31 rotates to 90°, the vertical displacement is the smallest and the horizontal displacement is the largest. As the first transmission component 31 rotates further, the vertical displacement gradually increases and the horizontal displacement gradually decreases until the movable plate 20 is closed.

[0052] Therefore, by controlling the central angle of the first transmission component 31 and its initial deflection angle, the movement trajectory of the movable plate 20 can be controlled to meet different practical needs.

[0053] Please refer to Figure 2 As shown, in some embodiments, at least one of the first transmission member 31 and the second transmission member 32 along the Y-axis direction is provided with a weight reduction groove 30c. This allows for lightweight design while ensuring that the structural strength meets the requirements, thereby reducing the output power requirements of the drive member 40 and lowering equipment and operating costs.

[0054] Preferably, both the first transmission component 31 and the second transmission component 32 are provided with weight reduction grooves 30c.

[0055] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, a mounting base 11 is also fixed on the side of the fixing plate 10 where the driving member 40 is provided, and the mounting base 11 is arranged around the through hole 111.

[0056] Mounting base 11 has first hinge seats 112 fixed at intervals along the X-axis direction, which are respectively hinged to the first transmission member 31, the output shaft 41 and the second transmission member 32. Each set of first hinge seats 112 includes two hinge frames located on both sides of the through hole 111 along the Y-axis direction.

[0057] By providing mounting bases 11 on the fixed plate 10 for mounting the transmission assembly 30, the mounting bases 11 can serve as reinforcing ribs to increase the structural rigidity of the fixed plate 10, and can also concentrate stress on each of the first hinge seats 112 to prevent deformation of the fixed plate 10 body.

[0058] Each set of first hinge seats 112 includes two hinge frames located on both sides of the through hole 111 along the Y-axis direction, which can limit the transmission component 30 and the drive gear 42 along the X-axis direction, releasing only the rotational degree of freedom, thereby further improving the operational stability of the mask assembly of this application.

[0059] Please combine Figure 2 as well as Figure 4 As shown, in some embodiments, a second hinge seat 21 is fixed on the movable plate 20, which is respectively hinged to the first transmission member 31 and the second transmission member 32;

[0060] When the movable plate 20 is closed, the second hinge seat 21 passes through the through hole 111. The hinge points of the first transmission member 31 and the second transmission member 32 with the second hinge seat 21 are located on the side of the fixed plate 10 where the driving member 40 is fixed, so as to prevent the arc segment 30b from interfering with the through hole 111 and further reduce the area of ​​the through hole 111.

[0061] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, two sets of transmission components 30 are provided on the fixed plate 10 along the Y-axis direction, and the driving component 40 is located between the two sets of transmission components 30. On the one hand, it can balance the weight and torque, and avoid the fixed plate 10 from being concave and deformed on one side due to the weight being concentrated on one side, or the situation of uneven load shaking caused by unilateral driving.

[0062] In addition, the two sets of transmission components 30 can also serve as system redundancy, providing load-bearing capacity when one set of transmission components 30 fails, thus preventing the movable plate 20 from falling.

[0063] Please combine Figure 1 as well as Figure 5 As shown, in some embodiments, the drive unit 40 further includes a motor 43, a worm 44, a worm wheel 45, and an output shaft 41. The motor 43 is fixed to the fixing plate 10 and the worm 44 is fixed on its motor shaft. The worm wheel 45 is fixed to the output shaft 41 and meshes with the worm 44. The output shaft 41 is poweredly connected to the first transmission unit 31.

[0064] By utilizing the self-locking property between the worm gear 45 and the worm 44, it is possible to ensure that the movable plate 20 remains stationary relative to the fixed plate 10 when the motor 43 is turned off without the need for additional locking devices. This satisfies the equipment's locking requirements while reducing equipment costs and minimizing internal space usage.

[0065] This application also provides a bathroom heater, including a bathroom heater body and the aforementioned mask assembly, wherein the fixing plate 10 is a mask fixed to the bathroom heater body, and the movable plate 20 is a light panel.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative 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 the utility model patent. 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 all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
