Abstract
The utility model discloses an electrical fan with 360DEG rotation, which can realize omnibearing for blowing air. The primary structure of the utility model has the technical proposal that an electrical motor (11) with a driving gear (17) is arranged in the bottom case (10) and a fan housing (30) is screwed on the bottom case (10); the bottom case (10) is provided with a whole fan mechanism which is uniformly distributed on the same circumference; each fan mechanism is composed of gear shafts (13), fan gears (12) which are arranged on the gear shafts and leaf fans (14); each leaf fan (14) is arranged in a corresponding blast pipe (20); the blast pipe (20) is arranged in the fan housing corresponding to the lower end of a guide tube (31), whereas, the upper end of the guide tube is provided with a concave flaring air outlet (32); a net shield (33) is arranged on the bottom part of the air outlet (32).
Description
The utility model relates to electric fan.
Existing electric fan adopts the mode of rotating fan head to realize bigger blowing scope more, and its rotating mechanism life-span is not long, and the blowing angle also can only reach 120 ° or 180 ° at the most, can't fully realize whole indoor wind flow, especially the cold air room.If it is then uneconomical economically to purchase many electric fans, and the Security of general electric fan is also relatively poor, often has child to play with the working life that flabellum damaged and influenced electric fan.
The purpose of this utility model is, designs a kind of 360 ° of comprehensive electric fans, can realize comprehensive blowing, has that Security is good, the characteristics of reliable performance.
The technical solution of the utility model is, it comprises the under casing that is provided with intake grill, the motor that driving gear is housed on the line shaft places this under casing, through junction button fan housing has been installed on the described under casing, its structural feature is, equally distributed several fans on week are installed in the under casing in same garden, described each fan is by gear shaft and be installed on it and the fan gear that is driven by described driving gear and the leaf fan that is installed in the gear shaft upper end are formed, each leaf fan all places corresponding airduct, described airduct is positioned at the lower end of the corresponding conduit of fan housing and is recessed tubaeform exhaust outlet on it, and windproof guard is equipped with in described exhaust outlet bottom.
Make below in conjunction with accompanying drawing and to further specify.
Description of drawings: Fig. 1 is the longitudinal sectional view (only having drawn a fan among the figure) of reflection practical structures, and Fig. 2 is the plan structure of fan housing, and Fig. 3 is the three-dimensional structure diagram of the separated attitude of relevant member, and Fig. 4 is integrally-built stereogram.In the drawings:
The 10-under casing, the 11-motor, the 12-fan gear, the 13-gear shaft, 14-leaf fan, the 15-intake grill, the moving button of 16-, the 17-driving gear, the 20-airduct, the 30-fan housing, the 31-conduit, the 32-exhaust outlet, the 33-protection net, 34-detains surely, the 40-wheel.
By accompanying drawing as can be known, the utility model comprises the under casing (10) that is provided with air inlet (15), the motor (11) that driving gear (17) are housed on the line shaft places this under casing (10), described under casing (10) is upper has installed fan housing (30) through junction button (deciding button (34) and moving the junction button of detaining (16) of the prior art that adopts in such as Fig. 1), its design feature is, several (for example 3 to 5) fans of evenly distribute on week (for example distribution shown in Figure 3) are installed in the under casing (10) in same garden, described each fan by gear shaft (13) and be installed in this gear shaft (13) upper and by described driving gear (17) drive the fan gear (12) of (such as the two direct drives structure of engagement) and be installed in as described in the leaf of axle (13) upper end fan (14) and form, each leaf fan (14) all places corresponding airduct (20), described airduct (20) is positioned at fan housing (30) corresponding pipe (31) lower end and is recessed tubaeform air outlet (32) on it, and protection net (33) is equipped with in described air outlet (32) bottom. Can also wheel (40) be installed under casing (10) bottom, so that mobile. Consisted of thus by a plurality of fans of Motor Drive, and each fan is separately to the electric fan of 360 ° of comprehensive blowings that an air discharge structure that is made up of described airduct, conduit, air outlet should be arranged.
Design principle of the present utility model and the course of work be, motor (11) highly rotates generation wind-force through gear (12) (17) and axle (13) band movable vane fan (14), and described wind-force is by airduct (12) Blown out by the conduit (31) in the fan housing (30) after concentrating, the wind that blows out is discharged radial distinguished and admirable through recessed tubaeform air outlet (32) water conservancy diversion again; Because motor (11) drives several by the blowing of fans of certain distribution, has realized the comprehensive blowing of 360 deg, there is not the dead angle and need not to adjust the fan orientation. Described protection net (33) plays the effect of safe handling. Because of cold air at the lower hot-air relatively aloft, so when air inlet (15) down below inspiration cold wind discharge through leaf fan (14) is powerful, outwards blow out through recessed tubaeform air outlet (32) rapidly, realized the cool wind blowing function function, the mobile effect of the air circulation that is highly advantageous to.
As known from the above, the utility model is a kind of 360 ° of Omnibearing electric fans, realized comprehensive blowing, simple in structure, safety and reliability good, handsome in appearance, overall construction design is changeable, can work as the hanging decoration blowing or not be subjected to spatial constraints when the ceiling fan use, loading onto wheel (40) can arbitrarily move, convenient and practical. The design has injected new life for the electric fan that has become wilting at present.
Embodiment: a kind of the utility model device according to said structure, adopt three groups of fans, it is in 120 ° of distributions, in under casing (10), directly mesh fan gear (12) and drive (14) air draft of leaf fan by driving gear (17), monnolithic case is to connect hemisphere (being with tubaeform exhaust outlet) fan housing on the cylindricality under casing of garden, and overall dimensions (garden, bottom surface diameter * height) is φ 500 * 550mm.Also can design the product of series specification size as required.
Claims (2)
1, a kind of 360 ° of comprehensive electric fans, it includes the under casing (10) that is provided with intake grill (15), the motor (11) that driving gear (17) are housed on the line shaft places this under casing (10), described under casing (10) is gone up and through junction button fan housing (30) has been installed, it is characterized in that, equally distributed several fans on week are installed in the under casing (10) in same garden, described each fan is by gear shaft (13) and be installed on it and be made up of the leaf fan (14) that described driving gear drives the fan gear (12) of (17) and is installed in described axle (13) upper end, each leaf fan (14) all places corresponding airduct (20), described airduct (20) is positioned at the lower end of the corresponding conduit of fan housing (30) (31) and is recessed tubaeform exhaust outlet (32) on it, and protection net (33) is equipped with in described exhaust outlet (32) bottom.
