Abstract: A sucker and film combination including a sucker comprising a body useful for attaching the sucker to a surface. A column is in contact with the body. The column includes a groove useful for engaging a film. A stem useful for detaching the body from the surface is in contact with the body. The film comprises a substantially planar surface. A through-hole wall extends through the substantially planar surface. The through-hole wall defines a column receiver portion and a stem receiver portion.

Abstract: An ornament assembly for an exhaust pipe of a vehicle has a sleeve, an axle, a spring and a propeller. The sleeve is secured in an opening end of the exhaust pipe. The axle is moveably received in the sleeve. The axle has a first end exposed from the sleeve and a second end extending into the sleeve. The spring is received in the sleeve and is securely attached between the sleeve and the second end of the axle. The propeller is rotatably mounted on the first end of the axle. Accordingly, the propeller will rotate when the waste gases are emitted from the exhaust pipe, and the axle will move relative to the sleeve. This can provide an excellent visual effect to the vehicle, and the appearance of the vehicle is improved.

Abstract: This invention relates to one kind of ventilation system, with independent and modular components including a smoke extraction part, a joining component, a drying component, and a water tank that can be installed in a kitchen to constitute a smoke extractor. The system can be installed flexibly depending on the space and layout of the pre-existing kitchen, avoiding the waste of dismantling the original equipment and buying a whole set of smoke extractors. Therefore, with better industrial availability, this product can be installed in homes and restaurants.

Abstract: A smokeless barbecue grill includes a tubular frame with a grill received therein and an annular gap defined between the frame and the grill. A plurality of nozzles are located around and below the grill and a divider is located below the nozzles, wherein the divider has a protrusion extending toward the grill with a hole defined therethrough so that water sprayed from the nozzles containing the grease and ash particles drops through the hole. A ventilator is located below the divider to suck air from the frame.

Abstract: A sucker includes a conical body, a neck portion formed at one end with the top end of the conical body, a flexible ring formed with the other end of the neck portion, wherein the flexible ring may have two ears provided thereon, and two stems, each of which is integrally formed with the flexible ring at the position adjacent to each of the ears with its first end and formed with the conical body with its second end. Wherein the second end can be formed as a slice or formed with a plurality of legs, e.g. two legs. To remove the sucker from a surface to which it has been attached, a user needs only to find and identify by touch one of the ears, and then pull the ear to pull the corresponding stem so as to raise a part of a peripheral edge of the body, thereby the sucker can be removed in an easy and convenient manner.

Abstract: A smokeless barbecue device includes a casing having a water tank disposed to a lower end thereof and a food processing device disposed in an open top thereof. A meshed member is disposed transversely in the casing and below the food processing device. A pump is disposed to the water tank and from which a pipe extends having a plurality of sprays disposed thereto which are located above the meshed member. At least one ventilator is disposed to the casing and located below the meshed member, and a valve device is disposed to the water tank.

Abstract: A sucker structure including a body (50), a pair of stems (60), each of the stems having a first end (62) for connecting to the body (50) and a second end (64), and a ring-like piece (70), which is open ended and has two opposite ends (72) separated from each other and being connected to the stem (60) respectively. When a user pulls the ring (70) of the sucker to remove it from a surface, the force applied by the user becomes concentrated on at least one edge portion (52) of the body of the sucker via at least one stem (60), since the stems are separated from each other. Therefore, the user can easily remove the sucker from the surface by applying only a little force without concern about the angle at which the force is to be applied.
