Abstract
The invention discloses a floor fan. The floor fan comprises a base, an upright and a fan head, wherein the upright is arranged on the base and the fan head is arranged on the upright. The fan head comprises a rear mesh enclosure, a front mesh enclosure, a motor and fan blades, wherein the motor is arranged in the rear mesh enclosure and the fan blades are connected with an output shaft of the motor and extends into the front mesh enclosure. Specifically, a convection ring is further integrally formed on the side portion of the front mesh enclosure and the side faces of the fan blades are completely shielded by the convection ring. Thus, in the process of actual work, air flow enters from the rear end of the fan head and flows out of the front end of the fan head horizontally under the limitation of the conversion ring, turbulent flow is not prone to generation, noise is low, and the flowing efficiency of the air flow is effectively improved.
Description
Technical field
The present invention relates to ventilation plant field, relate in particular to a kind of by the gain stand fan of air current flow efficiency of convection current.
Background technique
Fan is a kind of by allowing Air Flow take away the cooling device of heat, is a kind of indoor electric appliance of traditional, environmental protection.Common fan is to drive the moving axial flow fan that forms wind of the direct turbulent airflow of multiple flabellums of rotating around axis by motor, and this fan is traditional common electric fan form, and desk fan and stand fan etc. all belongs to the fan of this structure.For the object contact outside preventing is to flabellum, some guard shields are conventionally set around flabellum, but air more easily produces noise after guard shield flows, and hinder gas flow, reduce the flow effect of wind.
Summary of the invention
The object of the present invention is to provide one simple in structure, can strengthen air current flow efficiency, and the little convection fan of noise.
For reaching above object, the present invention adopts following technological scheme.
A kind of stand fan, comprising: base, and be arranged on the column on base, and be arranged on the fan head on column, it is characterized in that, described fan head comprises guard, is arranged on the motor in guard, the flabellum being connected with motor output shaft; Be provided with the convection cell that flabellum side is blocked completely at the sidepiece of guard.
As further illustrating of above-mentioned stand fan, described guard is made up of mutual dismountable rear net cover and front mesh enclosure, and described convection cell is one-body molded on front mesh enclosure, and described flabellum extend in front mesh enclosure.
As the further improvement of above-mentioned stand fan, described convection cell is replaced by fixed rear net cover and front mesh enclosure snap close ring, and the front and back width of described snap close ring is greater than the perpendicular distance of flabellum front end and back end.
As further illustrating of above-mentioned stand fan, described column comprises upper pillar stand and lower pillar stand, is provided with Telescopic Fixed seat on lower pillar stand, and upper pillar stand is inserted in Telescopic Fixed seat and forms the adjustable flexible connection of relative position.
As the further improvement of above-mentioned stand fan, the flexible connection that described relative position is adjustable refers to, is provided with the lifting spring for adjusting upper pillar stand position and is used for upper pillar stand to enter line-locked lifting key and by key spring on Telescopic Fixed seat.
As further illustrating of above-mentioned stand fan, in base, be provided with the rotary disk basement being connected with column, the stepper motor being connected with rotary disk basement, and the control panel being connected with stepper motor.
As the further improvement of above-mentioned stand fan, be provided with the manual head-shaking switch being connected with control panel at the top of column.
Compared with prior art, a kind of convection fan provided by the invention has following beneficial effect:
One, by be provided with the convection cell that flabellum side is blocked completely at the sidepiece of guard, when real work, air-flow enters from fan head rear end, and the flatly front end outflow from fan head under the restriction of convection cell, be difficult for producing flow-disturbing, not only noise is little, and actual gain air current flow efficiency.
Two, due to convection cell and the front mesh enclosure structure that is formed in one, the outer device without increase, not only simple in structure, and between convection cell and guard, there is not vibrations sounding phenomenon, further reduce the overall noise of stand fan.
Three,, by Telescopic Fixed seat is set between upper pillar stand and lower pillar stand, user only need press lifting button and can conveniently realize the adjusting of stand fan height, easy to operate.

Embodiment
Understand better essence of the present invention for convenience of those of ordinary skill in the art, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
As shown in Figure 1, a kind of stand fan, comprising: base 1, is arranged on the column 2 on base 1, and is arranged on the fan head 3 on column 2.
Wherein, described fan head 3 comprises rear net cover 31, and front mesh enclosure 32 is arranged on the motor 33 in rear net cover 31, and is connected with motor output shaft and reaches the flabellum 34 in front mesh enclosure 32.Especially, have a convection cell 4 the sidepiece of front mesh enclosure 32 is also one-body molded, this convection cell 4 blocks the side of flabellum 34 completely.Like this, when real work, air-flow enters from fan head 3 rear ends, and the flatly front end outflow from fan head 4 under the restriction of convection cell 4, is difficult for producing flow-disturbing, actual gain air current flow efficiency.
Described column 2 comprises upper pillar stand 21 and lower pillar stand 22, is provided with Telescopic Fixed seat 23 on lower pillar stand 22, and upper pillar stand 21 is inserted in the adjustable flexible connection of Telescopic Fixed seat 23 interior formation relative position.Particularly, the flexible connection that described relative position is adjustable refers to, is provided with the lifting spring for adjusting upper pillar stand position and is used for upper pillar stand to enter line-locked lifting key and by key spring on Telescopic Fixed seat 23.When use, only need press lifting button, flick the adjusting that can conveniently realize stand fan height by key spring; In the time both highly reaching provisioning request, unclamp lifting key, easy to operate.
In described base 1, be provided with the rotary disk basement 11 being connected with column 2, the stepper motor 12 being connected with rotary disk basement 11, and the control panel 13 being connected with stepper motor 12.Be provided with the manual head-shaking switch 5 being connected with control panel 13 at the top of column 2, user can directly realize the control of shaking the head of stand fan by manipulating manual head-shaking switch 5.
As the one conversion mode of execution of the present embodiment, described convection cell is replaced by fixed rear net cover and front mesh enclosure snap close ring, only the front and back width of snap close ring need be greater than to the perpendicular distance of flabellum front end and back end.
