Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

As shown in fig. 1-2, the present invention provides a range hood 100, the range hood 100 having a smoke collection hood 110. The smoke collection hood 110 is generally disposed below the range hood for collecting rising smoke. The fume collecting cover 110 includes a rolling shutter device 200. The rolling shutter device 200 may prevent oil smoke generated during cooking from being diffused to the surroundings. The rolling shutter device 200 includes a rolling shutter device 210 and a rolling shutter 220. The rolling shutter device 200 has two states, a rolled-up state and a rolled-out state. When the rolling shutter device 200 is in the rolling state, the rolling shutter device 210 may roll the rolling shutter 220 therein. When the user needs to use, the rolling screen 220 can be rolled out by the rolling device 210. After the roll screen 220 is unfolded, it can form a curtain at a corresponding region below the roll screen device 200. Since the rolling screen 220 is stored in the winding device 210 by winding, a winding shaft may be provided in the winding device 210, and the rolling screen 220 is wound on the winding shaft. The winding device 210 is connected to the hood 110 to fix the rolling shutter device 200. The rolling shutter device 200 may be disposed at any one or more of the left, right, and rear sides of the smoke collecting hood 100 according to the use environment of the user. When a plurality of the devices are arranged, the devices can be operated independently and do not influence each other.

The winding shaft can perform the winding work of the roller shutter 220 manually or electrically. When the user needs to use the rolling screen device 200, the rolling screen 220 can be drawn out of the rolling screen device, and the rolling screen 220 is dropped to the height required by the user. When the user needs to retract the roller shutter 220, the retraction shaft can be rotated by the knob provided on the roller shutter device 200, so as to achieve the operation of retracting the roller shutter 220. Of course, a motor may be disposed on the winding shaft, and the motor drives the winding shaft to rotate, so as to perform the operation of unwinding and winding the roller shutter 220. A preferred embodiment will be described below and will not be described in detail here.

After the rolling curtain 220 is unfolded, the range hood works, a negative pressure area is formed in the area surrounded by the rolling curtain 220, the range hood 100 is more favorable for exhausting the lampblack, and therefore the lampblack is reduced from flowing to the surrounding environment of the kitchen. Moreover, as the unfolding height of the roller shutter 220 is reduced, the negative pressure region also sinks along with the roller shutter, and can be closer to the cooking bench, so that the oil smoke generated at the cooking bench can be gathered in time and further pumped into the smoke collecting hood 110, the oil smoke is prevented from flowing away, and the oil smoke absorption efficiency of the smoke machine 100 is improved.

Illustratively, the rolling shutter device 200 further includes a foldable telescopic rocker arm 230, an upper end of the foldable telescopic rocker arm 230 is connected to the rolling shutter device 210, and a lower end is connected to the rolling shutter 220. When the roll screen 220 is unfolded, the foldable telescopic rocker 230 is also unfolded as the roll screen 220 is unfolded. Because the rolling shutter 220 is soft, it is easy to swing freely after being unfolded. The collapsible telescopic rocker arm 230 can be collapsed only in the direction in which the furling apparatus 100 extends, but does not collapse or deform in the horizontal and vertical directions in the direction in which the furling apparatus 100 extends. Therefore, when the foldable telescopic rocker arm 230 is opened along with the roller shutter 220, the roller shutter 220 can be supported, so that the roller shutter 220 cannot swing randomly, and the use experience of a user is improved. Meanwhile, the foldable telescopic rocker arm 230 is completely folded and attached to the furling device 210 along the extending direction of the furling device 210. Thus, when the rolling shutter 220 is not used, the foldable telescopic rocker arm 230 can be folded along with the rolling shutter 220 and attached to the lower part of the rolling device 210, so that the occupied space is reduced.

Illustratively, the collapsible telescopic rocker arm 230 includes a first rocker arm 231 and a second rocker arm 232. The first swing arm 231 and the second swing arm 232 are pivotally connected together to have a foldable effect. A damping hinge connection 233 is provided on the pivot shaft. The damped hinge link 233 may provide resistance to the pivoting of the pivot shaft such that the damped hinge link 233 provides damping to the folding of the first and

second swing arms

231, 232. That is, the rolling screen 220 is not allowed to continuously fall due to its own weight, and the rolling screen 220 is not wound by the automatic winding device 300 without the help of the user, so that the rolling screen 220 can stop at the position desired by the user. The automatic retraction device 300 is a preferred embodiment and will be described in detail below. After the roller shade 220 is unfolded, the user may determine the height of the roller shade 220 to be unfolded according to the use situation, thereby adapting the roller shade apparatus 200 to different heights of cooktops and cigarette makers 100.

Illustratively, the collapsible telescopic rocker arm 230 includes a first collapsible telescopic rocker arm 240 and a second collapsible telescopic rocker arm 250, which are respectively located at both sides of the roll screen 220, as shown in fig. 2. The first and second collapsible

telescoping swing arms

240 and 250 are located on the front and rear sides, respectively, with respect to the machine 100. Therefore, the expanded rolling curtain 220 can be better supported, the gathering effect of the rolling curtain 220 on the oil smoke can not be influenced due to the fluttering of the rolling curtain 220, and the smoking effect of the cigarette making machine 100 is improved.

Illustratively, the roller shade apparatus 200 is removably coupled to the smoke collecting hood 110. For example, in an open kitchen, a user may need to provide roller shade devices 200 on the left and right sides and behind the machine 100 to better confine the smoke within the cooktop area. If the back of the machine is attached to a wall, as in a conventional kitchen, it may only be necessary to provide the roller blind apparatus 200 on either the left or right side of the machine 100. Thus, the user can selectively connect the roller shutter device 200 with the smoke collecting cover 110 according to the use condition of the user, and the operability of the user is improved.

Illustratively, the furling device 210 may be an automatic furling device. The automatic winding device can automatically wind the roller blind 220 into the winding device 210 with the help of the user, for example, the user can push the lower end of the roller blind 220 to complete the winding work of the roller blind 220 without manually rotating the winding shaft in the winding device 210 (as described above), thereby improving the user experience. The automatic retraction device 300 may take many forms, one of which 300 will be described in detail below.

As shown in fig. 3, the automatic retraction device 300 includes an elastic member 310, a winding rod 320, a head plug 330, a tail plug 340, and a winding shaft 350. The elastic member 310 is sleeved on the winding rod 320, and two ends of the elastic member 310 are respectively connected with the head plug 330 and the tail plug 340. The head plug 330 is coupled to the winding rod 320 such that relative displacement and rotation do not occur therebetween. The tail plug 340 is sleeved on the winding rod 320 and can rotate around the winding rod 320 on the winding rod 320. Wherein the tail plug 340 is also connected to the spool 350 such that no relative rotation occurs between the tail plug 340 and the spool 350. The roller shutter 220 is wound on the roller shaft 350. When the user pulls the roller shutter 220, the roller shutter 220 is wound on the winding shaft 350, and the winding shaft 350 is rotated around the winding rod 320, so that the roller shutter 220 is unwound. And the rotation of the spool 350 rotates the tail plug 340 around the winding rod 320. Since the tail plug 340 is connected to the elastic member 310, the elastic member 310 itself is twisted. The elastic member 310 may be a spring or an elastic member such as a rubber band. Here, a spring is taken as an example. When the spring is twisted, the force for twisting the spring is converted into elastic potential energy and stored in the elastic potential energy. Until the force pulling the rolling screen 220 disappears or is less than the elastic force of the spring, the spring converts its elastic potential energy into a torsion force, driving the tail plug 340 to rotate reversely. The tail plug 340 rotates the winding shaft 350 in a direction to retract the roll screen. The roller 350 takes up the roll screen 220.

Thus, the automatic winding effect is achieved. Incorporating the damped hinge connection 233 described above. If the resistance of the damped hinge connection 233 is greater than the elastic force of the elastic member in the automatic rolling device 300, the roll screen 220 can stay at any position without being rolled up by the user's pulling-loose. If the user needs to roll the roller shade 220 back into the automatic rolling device 300, the roller shade 220 is rolled into the automatic rolling device 300 as the user pushes upward by providing only an upward force to the roller shade 220 to counteract the resistance of the damping hinge connection 233.

Thus, by providing the automatic winding device 300, the user can easily wind the roller blind 220 into the automatic winding device 300 without manually or electrically driving the roller to rotate to achieve the same purpose. The user operation process is simplified, the product structure is simplified, and the cost is reduced.

Illustratively, the lower end of the roll screen 220 is provided with a pull rod 260. The pull rod 260 extends along the bottom edge of the roller shade 220. The pull rod 260 may extend through the bottom edge of the roll screen 220 or may be provided only on a portion of the bottom edge. Thus, the user can conveniently pull the rolling screen 220 out of the rolling device 210 by hand. When the rolling shutter 220 is retracted, the pull rod 260 is pushed upward. Meanwhile, both ends of the pull rod 260 are connected to the lower ends of the foldable telescopic rocker arms 230, respectively. Therefore, the quadrangle formed by the foldable telescopic rocker arm 230, the pull rod 260 and the furling device 210 can better support the rolling screen 220, and the rolling screen 220 cannot flap along with the airflow when being unfolded, so that the smoking effect of the cigarette making machine 100 is not affected.

Illustratively, the roller blind is made of canvas. The canvas is soft, and is favorable to rolling up curtain 220 and accomodate in roll-up device 210, and simultaneously, the canvas is very thin again, is favorable to reducing roll-up device 210's overall size. Because the rolling screen 220 is positioned around the cooker after being unfolded, the rolling screen is difficult to be stained with oil stains and water stains, and the oil-proof and water-proof coating is arranged on the surface of the rolling screen, so that the rolling screen is convenient for users to clean. The fireproof coating is disposed on the surface of the rolling shutter 220 to prevent high temperature generated during cooking from burning, thereby improving safety of users during use.
