Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, a range hood panel turnover mechanism 1 comprises:
the turning plate 11 is hinged on the shell of the range hood;
the connecting structures 12 are respectively connected to two sides of the turning plate 11;
the two sections of rotating shafts 13 are respectively connected with the connecting structures at the two sides of the turning plate 11;
and the double-output-shaft motor 14 is arranged between the two sections of rotating shafts 13, and the output ends of the double-output-shaft motor 14 are fixedly connected with the two sections of rotating shafts 13 respectively so as to drive the turning plate 11 to turn.
The utility model discloses a lampblack absorber turns over board mechanism 1 and uses dual output axle motor 14 as the power supply, directly through 13 simultaneous drive of pivot and the connection structure 12 drive that turns over board 11 both sides and be connected turn over board 11 and rotate, make it is more steady when the upset to turn over board 11. Because only used a dual output axle motor 14 to realize two side transmission to directly be connected in order to reduce middle drive disk assembly through pivot 13 and connection structure 12, compare with prior art, the utility model discloses a lampblack absorber inner space that lampblack absorber panel turnover mechanism 1 occupy is littleer.
The input voltage of the dual-output shaft motor 14 is preferably 12V based on the weight of the turning plate 11, and the dual-output shaft motor is small in size and suitable for electric appliances with small internal spaces, such as range hoods and the like. Moreover, according to the test of the applicant, the turnover of the turning plate 11 can be realized when the output power of the double-output-shaft motor 14 is greater than or equal to 45 w. Of course, the skilled person can also appropriately adjust the output power selection of the dual-output shaft motor 14 according to the specifications of the turning plate 11 and the connecting structure.
The rotating shaft 13 may be fixedly connected to the connecting structure 12, so that the connecting structure 12 rotates around the rotating shaft 13 to realize turning of the flap. The rotating shaft 13 can also be engaged with the connecting structure 12, and the turning of the turning plate 11 is realized through the relative movement of the rotating shaft 13 and the connecting structure 12. In this embodiment, the shaft 13 engages with the connecting structure 12.
Specifically, as shown in fig. 2, a first arc-shaped rack 121 is disposed on the connecting structure 12; the end of the rotating shaft 13 is provided with a gear 131, and the gear 131 is engaged with the first arc-shaped rack 121. Wherein the gear 131 is a part of the rotating shaft 13.
Preferably, the connecting structure 12 further has a second arc-shaped rack 122, and the first arc-shaped rack 121 and the second arc-shaped rack 122 are disposed oppositely;
an arc-shaped guide groove 123 is formed between the first arc-shaped rack 121 and the second arc-shaped rack 122, and the gear 131 is disposed in the arc-shaped guide groove 123 and is engaged with the first arc-shaped rack 121 or the second arc-shaped rack 122.
Thus, the arc-shaped guide groove 123 formed by the first arc-shaped rack 121 and the second arc-shaped rack 122 limits the moving direction of the gear 131, and prevents the gear 131 from being separated from the connection structure 12. As the position of the connection structure 12 is changed, the gear 131 is engaged with the first or second arc- shaped rack gear 121 or 122. Because the arc-shaped guide groove 123 plays a guiding role, no additional guide part is needed, the overall weight and volume of the connecting structure 12 are reduced, and the output power requirement on the dual-output-shaft motor 14 is further reduced.
In order to avoid that the gear 131 is simultaneously meshed with the first arc-shaped rack 121 and the second arc-shaped rack 122, the gear 131 cannot move in the arc-shaped guide groove 123, so that the range hood flap mechanism 1 is blocked, and the width of the arc-shaped guide groove 123 and the diameter of the gear 131 need to be controlled. Specifically, as shown in fig. 3, when the gear 131 is engaged with the first arc-shaped rack 121 or the second arc-shaped rack 122, the minimum distance between the tooth top of the gear 131 and the tooth top of the first arc-shaped rack 121 or the second arc-shaped rack 122 which is not engaged is L, wherein L is greater than or equal to 0.1mm and less than or equal to 3 mm.
In order to further reduce the weight of the connecting structure 12, the connecting structure 12 is integrally arc-shaped, a through groove is formed on the connecting structure, the arc-shaped guide groove 123 is formed inside the through groove, and two side edges of the through groove are configured into the first arc-shaped rack 121 and the second arc-shaped rack 123.
The turning plate 11 is hinged with the shell of the range hood, and the end part of the connecting structure 12 is hinged with the turning plate 11. Compare in turn over board 11 only with connection structure 12 is connected, turn over board 11 and articulated with the shell of lampblack absorber, can alleviate the gravity that connection structure 12 bore, and then reduce the output power demand to dual output shaft motor 14, can reduce the risk that turns over board 11 and drop simultaneously. The hinged connection of the turning plate 11 and the connecting structure 12 can enable the turning plate 11 to automatically adjust the angle between the turning plate and the connecting structure 12 in the turning process, and the blocking is avoided.
Specifically, supports 111 are arranged on two sides of the turning plate 11, and the connecting structure 12 is hinged to the supports 111; the support 111 is disposed at a middle position of the flap 11 in the height direction.
The support 111 is arranged at the middle position, so that the support force of the support 111 to the turning plate 11 is more uniform, and the stability of the turning plate 11 during turning is improved.
The utility model also provides a range hood, as shown in fig. 4, which comprises the range hood panel turnover mechanism 1; the range hood further comprises a shell 2, a smoke inlet 3 is formed in the front side face of the shell, and a turning plate 11 of the range hood turning plate mechanism 1 is used for covering the smoke inlet 3;
the turning plate 11 is hinged with the upper edge of the smoke inlet 3. Wherein, the turning plate 11 and the upper edge of the smoke inlet 3 can be hinged through a hinge.
In a word, the utility model discloses a lampblack absorber turns over board mechanism has directly through pivot simultaneous drive with turn over the connection structure drive that board both sides are connected and turn over the board rotation, the lampblack absorber inner space that occupies is littleer turn over the board when the upset more steady. The turnover plate of the range hood using the range hood turnover plate mechanism is tightly matched and attractive when covering the smoke inlet.
