With the ventilating fan according to the embodiments of the present invention, although a switch is disposed, the cost is not increased and the area of an air path is not narrowed, and the switch can also be conveniently operated.

Ventilating fan

A ventilator includes an opening formed on a bottom surface, a rectangular frame provided with a flange, a volute provided with a fan motor inside, and a connector connected to an air outlet of the volute. Four side surfaces of the frame excluding the top surface and the bottom surface tilt towards the outer lower side in a direction from the top surface to the bottom surface, and the opening area of the bottom surface is larger than that of the top surface. The ventilator saves packaging and installation costs, and further facilitates installation between the roof and the ceiling.

Ventilation fan

A ventilating fan includes a sirocco fan disposed in a box-shaped body and an adapter connected to an air outlet of the sirocco fan. The sirocco fan is composed of two opposite scroll plates with scroll shapes and a casing plate sandwiched between the two scroll plates. An overall air inlet of the sirocco fan is disposed on the first scroll plate and a central line of the air outlet of the adapter is offset towards the second scroll plate. The present invention is advantageous in that no turbulence is generated at the adapter and the wind amount of the ventilating fan is thus ensured and noise is reduced. Therefore, the present invention can provide a small air blowing device with high efficiency and improve stability of performance of the product.

A ventilating device includes a rectangular frame, a louver, an adapter, a helix shell and a circuit board box. A mounting base at a bottom surface of the helix shell is configured for installation of a plurality of functional units thereon. The mounting base is provided with a base circuit board for interfacing with the functional units, and the circuit board box is coupled to the mounting base by a lead wire. Both the circuit board box and the mounting base include a hole, through which the lead wire passes. These holes are arranged in a linear manner in an up-down direction arranged at the side towards an air outlet. The plurality of functional units are configured to be freely assembled or disassembled individually to or from the mounting base.

Ventilating device

The present invention provides a ventilating fan. In the ventilating fan, first and second flangings are extended outwards from vertical side edges and horizontal side edges of the air inlet of the adapter respectively, outer edges of the first flangings are firstly bent to form both side surface, and then edges of the both side surfaces are bent to form edge surfaces, and the first flangings, the side surfaces, and the edge surfaces confine open grooves; protrusions are disposed on an outer periphery of the air inlet, and a slot is formed between the protrusion and the first or the second flanging; and first folded sheets are extended outwards from both vertical side edges of the air outlet of the casing; and an edge of the air outlet of the frame abuts against and is clamped in the slot.

The present invention discloses a ventilating fan mounted on a wall of an indoor side of a wind path therethrough from the indoor side to an outdoor side. The ventilating fan includes a ventilating fan hood, a filtering member, a ventilating fan body, and a ventilating fan mounting member. The filtering member is integrally formed by a frame provided with an engagement that is engaged with the ventilating fan body and a filtering screen located within the frame. The ventilating fan according to the present invention has the advantages that the filtering member can be fixedly mounted to the ventilating fan body in a simple structure manner without using fasteners such as screws, so as to facilitate the operation and save the working time. Moreover, the filtering member is not blown off to fall off when the ventilating fan hood is removed. In addition, the mounting of the filtering member in a reverse order is eliminated.

The present invention discloses a ventilating fan including a ventilating fan body located on the indoor side, an outdoor pipe hood located on the outdoor side, a ventilating fan mounting member located between the ventilating fan body and the outdoor pipe hood, and a panel removably mounted to the front of the ventilating fan body, the ventilating fan mounting member includes a cylinder and a flange, the outdoor pipe hood includes a pipe hood base and a back cover, the pipe hood base includes a base plate with a circular opening and a pipeline fixing ring removably mounted to the base plate; and, a hollow expansion pipe being connected to the cylinder of the ventilating fan mounting member at one end and connected to the pipeline fixing ring at the other end. The present invention has advantages of easy mounting of the expansion pipe.

A packing structure including an external packing carton consisting of a top surface, a bottom surface and side surfaces connected with one another and one or more small packing cartons, wherein at least one side surface of the external packing carton is provided with one or more folding portions, each folding portion consisting of one or more folding pieces which are folded to form an opening with a size mating with the size of the periphery of the small packing carton. The packing structure of the present disclosure is easy to be transported, cost reducing and friendly to the environment.

Packing structure including a large carton and smaller cartons contained therein

A ventilation fan mounting structure includes a bracket assembly which is to be mounted to opposite two side flanges of a ventilation fan and includes a first bracket and a second bracket each formed in a U shape, wherein each of the first bracket and the second bracket includes two side members and a connection member connecting the two side members, the connection members and the side members of the first and second brackets are connected to each other by shafts, the side members are rotatable around the shafts, and a position-limit portion is disposed to the connection member to limit a rotation range of the side member. With the ventilation fan mounting structure according to the embodiments of the present invention, the mounting of the ventilation fan can be simply and conveniently completed even if the distance between the ceiling and the roof is small.

Ventilation fan mounting structure

A ventilating fan, includes a frame provided with an opening, a fan disposed in the frame, a panel covering the opening of the frame and allowing air passing through and a lighting device disposed in the panel. The lighting device includes a lampshade, in which a lighting part is placed, and a circuitry box of a controller for controlling the lighting part. A gap is formed in a connection between the circuitry box and the panel such that a water discharge structure communicated with outside of the circuitry box is formed. Advantages of the present invention includes that a gap communicated with outside of the circuitry box is provided in a connection between the circuitry box and the panel, which allows water to be discharged through the gap from inside of the panel, even water would enter into inside of the circuitry box, thus safety operation of the product is ensured.
