Abstract
The utility model discloses a fan capable of being fixed on a waistband. The fan is characterized in that the fan comprises a centrifugal fan positioned in a housing; an air inlet covered by a protective screening is formed on one side of the centrifugal fan; an air outlet is formed on the other side of the centrifugal fan; the centrifugal fan is connected with a battery switching assembly; the back part of the centrifugal fan is provided with a hook used for fixing the centrifugal fan on the waistband; the air outlet is connected with a fanning hose; the fanning hose is provided with another hook used for fixing the fanning hose along the waistband; and a plurality of fanning holes fanning upwards are formed along the fanning hose. The fan capable of being fixed on the waistband has the advantages of occupying small space, being capable of fixed on the waistband, fanning from bottom to top, preventing the back part from sweating and playing the cooling function.
Description
Technical field:
The utility model relates to a kind of fan, particularly relates to a kind of fan that is fixed on the waistband, belongs to the technical field of fan.
Background technique:
Fan is a kind ofly to drive flabellum rotation by electric power, reaches the household electric appliance that make air quicken circulation, is mainly used in cooling and heatstroke-eliminating and ventilating air.The people that makes of fan feels that nice and cool cardinal principle is by the rotation of motor driving flabellum, quickens the circulation of human body surrounding atmosphere, human body having speeded up of pore transpiring moisture from the skin, because the heat that the water evaporation process is taken away increases, it is nice and cool that the people feels.
Fan can be divided into ceiling fan, desk fan, ventilation fan, rotary blade fan by structure, air conditioning fan (being air-cooling fan) etc.Many fans have also been used electronic technology and micro-computer technology, can remote controls, but its main motor-driven principle is constant basically.
The critical piece of fan is: Wechselstrommotor.Its working principle is: hot-wire coil is stressed and rotate in magnetic field.The reformulations of energy is: electric energy mainly is converted into mechanical energy, simultaneously because coil has resistance, so inevitably some electric energy will be converted into interior energy.
Indoor temperature does not only reduce, can raise on the contrary (to suppose that the room and the external world do not have heat transmission) during fan work.One of let us is analyzed the reason of temperature rising: during fan work, because the coil of electric current by electric fan arranged, lead has resistance, thus can inevitably produce the outside heat release of heat, so temperature can raise.Can but why people feel wool-like fabric? because the body surface of human body has a large amount of sweat, after electric fan worked together, indoor air can flow, so just can promote the evaporation rapidly of sweat, in conjunction with " evaporation needs to absorb a large amount of heats ", it is nice and cool that old friends can feel.
Being configured to of fan: rotor: form by magnet, flabellum and axle; Stator: form by silicon steel plate, bobbin and bearing; Control circuit: control its coil conducting via circuit and produce the inner excitatory rotor rotation that makes by the IC induced magnet N.S. utmost point.
The kind of fan has ceiling fan, desk fan, stand fan, wall fan, cabin fan etc.; The branch of shaking the head He do not shake the head is arranged, the rotary blade fan that also has in the desk fan again; Have in the stand fan shake the head, blade-rotating.Also having the little electric fan of a kind of gentle breeze, is to be hung in specially in the mosquito net, sleep in evening in summer, and a gentle breeze is blowing immediately once opening it, and the feel of can sleeping restfully also can be not sick.
Fan of the prior art the common shortcoming that exists be: can't carry use, when people go out, especially summer, often weather is warmmer, perspires and is got wet in back and armpit easily, and is very unbecoming, especially for the civil servants, since wear shirt, more unbecoming after being made soaked with sweat, can't work on.
The model utility content:
The technical problems to be solved in the utility model is: fan of the prior art can't be carried use, when people go out, especially summer, often weather is warmmer, perspires and is got wet in back and armpit easily, and is very unbecoming, especially for the civil servants, since wear shirt, more unbecoming after being made soaked with sweat, can't work on.
For solving the problems of the technologies described above, the utility model discloses the fan on a kind of novel be fixed in waistband, particular content is as follows:
A kind of fan that is fixed on the waistband, it is characterized in that: described fan has the centrifugal blower that is arranged in the shell, described centrifugal blower one side is provided with the suction port that is covered by protective net, opposite side is provided with the air outlet, be connected with the cell switch assembly on the described centrifugal blower, described centrifugal blower back has is fixed in buckling on the waistband; Described air outlet is connected with the blowing flexible pipe, has the hook that the blowing flexible pipe is fixed along waistband on the described air blowing flexible pipe, and forms a plurality of blowhole that are directed upwardly along the blowing flexible pipe.
Preferably, described hook is formed with a plurality of.
Preferably, described fan has the wind speed by-pass cock.
Preferably, described air outlet towards with described buckle vertical.
The beneficial effects of the utility model are: adopt the fan that is fixed on the waistband of the present utility model, and smaller and more exquisite being fixed on the waistband, thus wind blows afloat from beneath, thus avoid the back to perspire, and play nice and cool effect.
Description of drawings:
Fig. 1-3 is meant the schematic representation that is fixed in the fan on the waistband described in the utility model;
Reference character 1-centrifugal blower wherein, the 2-suction port, 3-cell switch assembly, the 4-exhaust outlet, 5-buckles, the 6-flexible pipe of drying, 7-blowhole, 8-hook, 9-waistband.
Embodiment:
Now in conjunction with the accompanying drawings the utility model is described further.
As Figure 1-3, a kind of fan that is fixed on the waistband, it is characterized in that: described fan has the centrifugal blower 1 that is arranged in the shell, described centrifugal blower 1 one sides are provided with by protective net (sees for clear, not shown) suction port 2 that covers, opposite side is provided with air outlet 4, is connected with cell switch assembly 3 on the described centrifugal blower 1, and described centrifugal blower 1 back has to be fixed in and buckles 5 on the waistband 9; Described air outlet is connected with blowing flexible pipe 6, has the hook 8 that the blowing flexible pipe is fixed along waistband 9 on the described air blowing flexible pipe, and forms a plurality of blowhole that are directed upwardly 7 along blowing flexible pipe 6.
Preferably, described hook 8 is formed with a plurality of.
Preferably, described fan has the wind speed by-pass cock.
Preferably, described air outlet 4 towards with described buckle 5 vertical.
The beneficial effects of the utility model are: adopt the fan that is fixed on the waistband of the present utility model, and smaller and more exquisite being fixed on the waistband, thus wind blows afloat from beneath, thus avoid the back to perspire, and play nice and cool effect.
