Description
Technical field
This utility model relates to fan, especially relates to a kind of hand-held bladeless fan shell.
Background technology
Bladeless fan is also air multiplier, it can produce the cool breeze that nature is lasting, because of on-bladed, have will not cover dust or hurt misplug into finger, and it is peculiarly shaped, appearance not only streamline but also salubrious, technology comes from air blades hand dryer, the principle of hand dryer be utilize air multiplier be allow air from 1.3 mm wides and around annulus rotate otch produce by boasting, the air capacity passed through can increase to 15 times, and speed per hour the highest can increase to 35 kilometers/hour.Current portable bladeless fan is the most, but it is primarily present following deficiency: air inlet design is unreasonable, it is unsuitable for hand-held, fan overall structure is unreasonable and carries inconvenience, during hand-held use, the body-sensing of hand is poor, and hand easily feels tired, it is necessary to design a blower-casting overcoming drawbacks described above, it is simple to be suitable for.
Utility model content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is to provide one to contribute to being easy to carry, and body-sensing is excellent, and tireless hand-held bladeless fan shell is held in hand control.
In order to achieve the above object, this utility model is achieved through the following technical solutions:
The technical program is a kind of hand-held bladeless fan shell, including outer cover body, described outer cover body includes annular airflow hole and Handheld Division, wherein outer cover body is rectangular shape, described annular airflow hole is arranged in outer cover body top, described handgrip part is in outer cover body bottom, the left and right side of described Handheld Division is equipped with strip projection, and the rounding conical surface is the most all become at the back side of Handheld Division, and it being transitioned into the lower limb in annular airflow hole in the upper end of taper seat by arc surface, the air inlet of fan is arranged at the front of Handheld Division.
Compared with prior art, the beneficial effects of the utility model are: novel structure of the present utility model, take into full account that user hand grasps the physics body-sensing of fan, loosen the grasping of hand, the hand of user is not easily tied, and the preposition setting of air inlet does not affect the hand control to fan, being easily carried on the whole, the suitability is strong.
Other optimize or optimal way also includes:
The drift angle of the cone at 1, described taper seat place is 40 degree, takes into full account and the suitability of human hands tiger's jaw position shape, improves the hand grasping body-sensing to fan, it is not easy to tired.
The central angle that the concentric circular at 2, described arc surface place is corresponding is 30 degree, sufficiently reduces the thickness at position, annular airflow hole, makes entirety the lightest, be also easy to carry.
3, described strip projected parts is arranged horizontally on the left and right side of Handheld Division, and flushes with the edge of left and right side, improves the frictional force that hand grasps, more laborsaving, slows down the degree of fatigue of hand.
4, described air inlet becomes lattice-shaped, and is arranged in the middle part in face before and after Handheld Division, contributes to improving further the draught capacity of wind inlet of fan.
Accompanying drawing explanation
This utility model will illustrate by example and with reference to the appended drawing, wherein:
Fig. 1 is front view of the present utility model；
Fig. 2 is side view of the present utility model；
Fig. 3 is the top view of utility model.
Labelling in figure: outer cover body 1, annular airflow hole 2, Handheld Division 3, have strip projection 4, the rounding conical surface 5, arc surface 6, air inlet 7.
Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As shown in Figure 1 to Figure 3, a kind of hand-held bladeless fan shell, including outer cover body 1, described outer cover body 1 includes annular airflow hole 2 and Handheld Division 3, wherein outer cover body is rectangular shape, described annular airflow hole is arranged in outer cover body top, described Handheld Division 3 is positioned at outer cover body 1 bottom, the left and right side of described Handheld Division 3 is equipped with strip projection 4, it is arranged horizontally on the left and right side of Handheld Division 3 as optimizing strip projected parts 4, and flushes with the edge of left and right side, to improve the frictional force that hand grasps, more laborsaving, slow down the degree of fatigue of hand.The most all becoming the rounding conical surface 5 at the back side of Handheld Division 3, the drift angle as the cone optimizing the rounding conical surface 5 place is 40 degree, takes into full account and the suitability of human hands tiger's jaw position shape, improves the hand grasping body-sensing to fan, it is not easy to tired.Being transitioned into the lower limb in annular airflow hole 2 in the upper end of the rounding conical surface 5 by arc surface 6, the central angle corresponding as the concentric circular optimizing arc surface 6 place is 30 degree, sufficiently reduces the thickness at position, annular airflow hole 2, makes entirety the lightest, be also easy to carry.The air inlet 7 of fan is arranged at the front of Handheld Division, becomes lattice-shaped as the air inlet 7 described in optimizing, and is arranged in the middle part in face before and after Handheld Division 3, contributes to improving further the draught capacity of wind inlet of fan.
This utility model has taken into full account that user hand grasps the physics body-sensing of fan, when grasping fan, the rounding conical surface 5 of the first web part of hand with the back side, Handheld Division 3 is connected, the thumb of hand and other fingers are held in both sides, Handheld Division 3 respectively, and contact with strip projected parts 4, the hand of user is not easily tied, and the preposition setting of air inlet does not affect the hand control to fan, being easily carried on the whole, the suitability is strong.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
