Detailed Description

In order that the utility model may be more readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

Example 1:

referring to fig. 1 to 8, the present embodiment provides a ventilation device, including: the fan comprises a shell 1, fan blades 2 arranged on the shell 1, a filter screen 3 and a driver for driving the fan blades 2 to operate. The drive here may optionally employ a motor 4. The fan blades 2 are mainly used for disturbing air to form air flow.

In the following, specifically, firstly, the housing 1 is provided with a vent 11, and in combination with the shape of the vent 11 in the conventional ventilation device, the vent 11 in the present embodiment is preferably designed to be circular, but of course, the vent 11 may also be designed to be rectangular or irregularly shaped, and the present embodiment is exemplified by the case of only the circular vent 11 in combination with the drawings. Next, the housing 1 is also formed with a receiving chamber for receiving the fan blades 2 in communication with the vent 11, and based on this construction, the fan blades 2 are operated in the receiving chamber, and the filter screen 3 is fitted at the vent 11 to form a filtering effect for the gas entering the vent 11. From the viewpoint of easy disassembly, the fan blade 2 is assembled into the accommodating cavity through the ventilation opening 11, and for the fan blade 2 installed in the accommodating cavity, the fan blade is preferably opposite to the ventilation opening 11, and the filter screen 3 is installed on the side end surface of the shell 1 facing away from the fan blade 2 to form a cover for the ventilation opening 11. Under such a structure, when the filter screen 3 and the fan blade 2 need to be disassembled, only the filter screen 3 needs to be disassembled first, and then the fan blade 2 needs to be disassembled.

Furthermore, a mounting beam 12 for fixing the fan blade 2 and the driver is provided in the housing 1. The mounting beam 12 is used not only for carrying the fan blades 2 but also for carrying the motor 4. The fan blade 2 may be detachably coupled to the mounting beam 12 by, for example, but not limited to, screws 8, and the motor 4 may be fixed to the mounting beam 12 by screws.

On the basis of the above structure, since the fan blade 2 needs to be driven by the motor 4 to operate, in order to facilitate the disassembly of the fan blade 2 from the mounting beam 12, the motor 4 does not need to be disassembled simultaneously, that is, the matching structure between the motor 4 and the fan blade 2 is simplified, and the following design is adopted in the embodiment:

a driving gear 51 is arranged at the power output end of the motor 4, and the fan blades 2 are meshed with the driving gear 51 through a driven gear 52. With this configuration, the fan blade 2 and the driven gear 52 can be assembled into a single unit, and the unit can be integrally mounted to or dismounted from the mounting beam 12. A central shaft hole 9 is communicated between the driven gear 52 and the fan blade 2, the central shaft hole 9 is matched with a polished rod part of the screw 8 to form the rotation fit of the screw 8 and the driven gear 52 and the fan blade 2, and then the screw 8 is matched with the mounting beam 12 in a fastening way to form the detachable fit of the gear and the fan blade 2 and the mounting beam 12.

Again in the following the cooperation between the sieve 3 and the housing 1:

in general, the sieve 3 is removably coupled to the housing 1 by means of at least one jaw and at least one stop lever provided on the housing 1. That is to say that the screen 3 is limited to the vent 11 of the housing 1 by the action of the catch and the catch lever, and there is no direct connection structure, such as a screw 8, between the screen 3 itself and the housing 1.

Specifically, firstly, the shape of the filter screen 3 is the shape, and in combination with the circular ventilation opening 11, the filter screen 3 preferably adopted in the embodiment is also in a circular structure, and the outer diameter of the filter screen 3 is slightly larger than the outer diameter of the ventilation opening 11, so that the filter screen 3 can be abutted with a part of the shell 1 surrounding the circumferential edge of the ventilation opening 11 to realize the covering of the filter screen 3 to the ventilation opening 11.

Secondly, in order to effectively ensure the covering effect of the filter screen 3 on the ventilation opening 11, in this embodiment, three claws and a stop lever are preferably distributed at intervals along the circumferential edge of the filter screen 3, although other structures are also possible, and in this embodiment, from the purposes of simplifying the structure and facilitating the disassembly and assembly of the filter screen 3, three claws and a stop lever are matched, and they are preferably in a uniformly distributed structure along the circumferential edge of the filter screen 3, that is, the stop lever and one of the three claws are relatively distributed. Under such structure, when dismouting filter screen 3, the hand only need stir a pin can, the simple operation is high-efficient.

Furthermore, in the present embodiment, the claw has an elastic clamping arm 6 adapted to press the filter screen 3 against the housing 1 to cover the vent 11. One end of the elastic clamping arm 6 is fixedly connected with the shell 1 through a fixed arm, and the elastic clamping arm 6 is matched with the fixed arm in an L-shaped included angle. In detail, a gap exists between the elastic clamping arm 6 and the shell 1 along the axial direction of the ventilation opening 11, and the gap just forms an axial space for accommodating the filter screen 3, so that one axial end of the filter screen 3 is pressed against the shell 1 in the axial dimension of the filter screen, and the other axial end is pressed against the elastic clamping arm 6. And here the limit of the axial dimension of the sieve 3 also serves to bring about a fit of the circumferential edge of the sieve 3 with the circumferential edge of the vent 11, thus preventing dust from entering the housing 1.

Based on the above structure, furthermore, from the circumferential edge of the filter screen 3, in the state that the filter screen 3 covers the ventilation opening 11, the circumferential edge of the filter screen 3 can be attached to the fixing arm, so that both the axial direction and the radial direction of the filter screen 3 are limited, and shaking is not easy to occur in the use process.

With respect to the bars of the present embodiment:

in general, the blocking rod is movably connected with the housing 1 to be suitable for switching the matching state of the blocking rod and the filter screen 3, when one end of the blocking rod is pressed against the filter screen 3, the filter screen 3 covers the ventilation opening 11, and when the blocking rod is separated from the filter screen 3, the filter screen 3 is separated from the ventilation opening 11.

As an alternative, illustrated in connection with the figures, the bar is pivotally connected to the housing 1. In more detail, the bars comprise a catch 71 pivotally connected to the housing 1 and a rotary rod 72 integrally connected to the catch 71 and adapted to abut against the filter mesh 3; wherein the rotary rod 72 is formed with a limiting surface 73 for pressing against the filter screen 3 and a stirring surface 74 for stirring the rotary rod 72. With this structure, the toggle surface 74 on the rotary rod 72 is toggled by hand, so that the rotary rod 72 can rotate around the buckle 71 relative to the housing 1, and in the process, the matching relationship between the limiting surface 73 and the filter screen 3 is switched.

Furthermore, the buckle 71 used in the present embodiment includes a cylindrical rotating portion 711 connected to the rotating rod 72, a limiting step 712 integrally connected to the cylindrical rotating portion 711, and a notch 713 penetrating the limiting step 712 and the cylindrical rotating portion 711; the notch 713 bisects both the cylindrical rotating portion 711 and the limiting step 712 into two half structures. The design of the notch 713 allows the buckle 71 to have a certain elastic deformation capability, and at the same time, the notch 713 allows the buckle 71 to have a sufficient compression avoidance space when being mounted on the housing 1. Based on this structure, when assembling buckle 71 and the corresponding mounting hole of casing 1, buckle 71 warp compression for buckle 71 can pass the mounting hole smoothly, and when buckle 71 and mounting hole assembly are put in place, cylindric rotary part 711 can with the inner wall normal running fit of mounting hole, and spacing step 712 is then located the casing 1 and is directed away from the one side end of rotary rod 72, plays and prevents buckle 71 and casing 1 and take place unexpected looks phenomenon that breaks away from.

In addition to the above structure, the buckle 71 may be deformed as follows: the buckle 71 further comprises a conical guide part 715 arranged at one side end of the limiting step 712, which is opposite to the cylindrical rotating part 711; wherein the notch 713 extends from the stop step 712 into the tapered guide 715. The design of the tapered guide 715 herein can improve the convenience and efficiency of assembling the buckle 71 with the housing 1.

In summary, regarding the ventilation device of the present embodiment, the specific disassembly process of the fan blade 2 and the filter screen 3 is as follows:

the rotary rod 72 of the stop lever is shifted, so that the rotary rod 72 is separated from the filter screen 3, and the filter screen 3 is moved towards one side of the stop lever at the moment, so that the filter screen 3 is gradually separated from the limit of the elastic clamping arm 6 of the clamping jaw, and the filter screen 3 is separated from the shell 1 conveniently; in this process, it should be noted that, the pivotal matching structure of the lever and the housing 1 in this embodiment is not only capable of realizing the pressing against the filter screen 3 and releasing the switching of the pressing against state of the filter screen 3 by the rotation of the lever relative to the housing 1, but also capable of forming a certain interval between the lever and the circumferential edge of the filter screen 3 and providing a certain moving space for the filter screen 3 to separate from the housing 1 by the interval when the lever releases the pressing against the filter screen 3, so that the filter screen 3 is required to move towards one side of the lever to enable the circumferential edge of the filter screen 3 to separate from the limit of the elastic clamping arm of the clamping jaw to smoothly separate from the housing 1, so that the design of the interval just provides the moving distance required by the separation of the filter screen 3 from the clamping jaw.

After the filter screen 3 is disassembled, the screws 8 connected with the fan blades 2 are disassembled from the mounting beams 12 through the ventilation openings 11, so that the fan blades 2 can be taken out from the ventilation openings 11 in the shell 1.

Through the two steps, the filter screen 3 and the fan blades 2 can be disassembled; for the fan blade 2 and the filter screen 3 after cleaning, firstly, the fan blade 2 is installed, and finally, the filter screen 3 is installed, and the installation operation process and the disassembly process are opposite.
