Detailed description of the invention
In the preferred embodiment of the present invention being described in detail below in conjunction with attached drawing, advantages and objects of the present invention can be with
It is better understood.In order to preferably show the relationship of each component in the accompanying drawings, attached drawing is not necessarily drawn to scale.In attached drawing:
Fig. 1 shows the perspective view of prior art fan；
Fig. 2 shows the perspective views of fan of the invention；
Fig. 3 shows the schematic diagram that fan of the invention is installed to lift car；
Fig. 4 shows the schematic block diagram of fan of the invention；
Fig. 5 shows the partial enlarged view of Fig. 4；
Fig. 6 a-6c shows the other forms of retention device of the invention.
Specific embodiment
It will be described in detail with reference to the accompanying drawings each embodiment according to the present invention.Here it is to be noted that it in the accompanying drawings,
It assigns identical appended drawing reference to component part substantially with same or like structure and function, and will omit about it
Repeated description.Term " successively including A, B, C etc. " only indicates putting in order for included components A, B, C etc., does not arrange
A possibility that except including other components between A and B and/or between B and C.
The attached drawing of this specification is schematic diagram, aids in illustrating design of the invention, it is schematically indicated the shape of each section
And its correlation.
In the following, detailed description is according to the preferred embodiment of the present invention referring to Fig. 2 to Fig. 6.
Firstly, referring to figs. 2 and 3, showing fan according to the present invention.Identical as prior art fan, fan is mounted on
The top of lift car, the fan include shell 1, and blade 2 and motor 3 are mounted in shell.
In fan of the invention, multiple air inlets are provided on shell.Specifically, it is provided in the side of shell more
A air inlet 12, without air inlet is arranged at top, to prevent the foreign matter from top from entering inside fan.In addition,
The bottom of shell is provided with multiple bottom air inlet mouths 13 and multiple air outlets 14.In prior art fan, it is not provided with bottom
Air inlet, although provided with bottom air inlet mouth, the top close contact of bottom air inlet mouth and lift car, this causes
It cannot be entered the wind from bottom air inlet mouth.In fan of the invention, the top of multiple bottom air inlet mouths 13 and lift car is at a distance of one
Distance, this allows air to enter inside fan from bottom air inlet mouth, thus the intake increased.It is to be understood that shell
The shell top surface in the case where fan is mounted on lift car, apart from elevator car top most portionafrom theasurface is referred at the top of body
Part, the bottom of shell refer to lift car top surface at a distance of closer shell bottom surface portion, what the side of shell referred to
It is the part in addition to top and bottom.
In fan of the invention, at least some air inlets of the multiple air inlet 12 are provided with retention device
15, the retention device is configured to keep air inlet direction I consistent with blade direction of rotation R, to reduce air intake resistance, and hinders
It keeps off and entering inside fan from extraneous foreign matter.The retention device 15 is integrally formed with shell.
Figure 4 and 5 show the working principle of the retention device of fan of the invention.As shown in Figures 4 and 5, retention device is arranged
In air inlet 12 towards the inside of shell, there is arcuate shape.This causes when the foreign matter from horizontal direction hits air inlet,
It will receive the blocking of the arch section of retention device, so that it is external to rebound back, referring particularly to shown in Fig. 5.
Other than the form of the retention device shown in the Figure 4 and 5, introduction according to the present invention, it is also contemplated that other out
The retention device of form.Particularly, when inside of the air inlet towards shell is arranged in retention device, retention device has opposite
In the shape that the plane where air inlet obliquely upwardly extends (as shown in Fig. 4 and Fig. 6 a).When retention device setting is being entered the wind
When mouthful deviating from the outside of shell, retention device has the shape obliquely extended downwardly relative to the plane where air inlet (such as
Shown in Fig. 6 b and Fig. 6 c).
Specifically, Fig. 6 a-6c shows the other forms of retention device.In Fig. 6 a, the retention device has two
Point, first part extends transversely with relative to the plane where air inlet 12, second part relative to first part vertically to
Upper extension.In figure 6b, the retention device has the writing board shape extended obliquely downward.In fig. 6 c, the retention device
With two parts, first part extends transversely with relative to the plane where air inlet 12, and second part is relative to first part
It extends vertically downward.
It should be appreciated that the form of retention device is without being limited thereto, as long as retention device can be realized its effect.
By that extraneous foreign matter can be stopped to enter wind well using the retention device that air inlet is arranged in of the invention
Fan is internal, to protect fan from the damage of foreign matter.
Described above is only explanation of the invention, and those of ordinary skill in the art is enabled completely to implement we
Case, but be not limitation of the present invention.Each technical characteristic of above-mentioned disclosure is not limited to disclosed and other feature group
It closes, those skilled in the art can also carry out other combinations between each technical characteristic according to goal of the invention, to realize the present invention's
Subject to purpose.
