Abstract
An impeller fan belongs to a simple air fan. The impeller fan has only one part. The impeller fan is suitable for installing on the machinery with swivel motion, in particular on the sewing machine. The impeller fan goes on with fanning for the operator, in order to cool and remove the heat. The impeller fan is manufactured by materials with stronger elasticity. The utility model is not easy to break off. The utility model has the advantages of simple structure, convenient assembly and disassembly, high durability and wide ranges of application. The utility model is the ideal simple air fan.
Description
The utility model belongs to a kind of fan, is particularly suitable for being installed in having rotation motion mechanically, and the operator is carried out pectinid, with refrigerant analgesic.
Domestic widely used machinery with rotation motion does not consider that generally a kind of fan assembly of design comes the operator is carried out pectinid at present, and when weather was hot, the operator can only lower the temperature analgesic by dedicated fan.Like this, expense height first, second floor space is big, and is undesirable.
The task of the utility model design is: a kind of Impeller fan is provided, and it can be as required, and ten minutes is installed in easily has rotation motion mechanically, can separate cold to operator's pectinid of working, and save dedicated fan.
Below in conjunction with accompanying drawing solution of the present utility model is described in detail.
Accompanying drawing is a main sectional view of the present utility model.
As shown in drawings, the utility model is a part only, and it is made up of blade 1 and wheel hub 2 two parts. Blade 1 is distributed in wheel hub 2 outer gardens on week, each sheet is identical with helical angle that axial line becomes, its helical angle size and Orientation and Impeller fan are relevant with respect to the gyratory directions of operator's position and Impeller fan, and the pectinid face of designing requirement blade 1 returns at Impeller fan should have a position and operator to concentrate to separate cool position (being generally head) relative and vertical when circling. The shape of blade 1, size and number can be decided according to the actual requirements. Wheel hub 2 endoporus are tight with on the revolving parts surface with gyration with some tension, hole shape should adapt with the revolving parts surface configuration that is engaged in it, and the resistance of suffered air was as degree when its tension force size then can overcome the Impeller fan pectinid enough take the frictional force that produces between wheel hub 2 endoporus and revolving parts surface. The benefit of restriction tension force is: when the careless mistake of operator was seriously collided a certain position of health or other article with rotating Impeller fan, extraneous resistance increase can make the Impeller fan endoporus skid and be protected. Whole Impeller fan should become static balance with respect to axial line, to avoid that the machinery that is mounted is produced unnecessary vibration.
The utility model employing has made than material such as the rubber of strong elasticity, purpose not only is its inexpensive light weight, endoporus is easy to swell and is easily mounted on the bigger revolving parts of various surface configuration differences and size difference, prior its quality softness that is, mistake is bumped blade and is difficult for hurting sb.'s feelings, also be difficult for fractureing, safe, durable.
Embodiment the most general of the utility model is exactly, and with the Impeller fan of shape---blade 1 is 8～12 as shown in drawings, helix angle is 60 °, the dextrorotation (not shown)---be installed on the sewing machine flywheel rim.When sewing machine was worked, Impeller fan just constantly to sewer's pectinid, felt more comfortable.When it cyclostrophic was cool, Impeller fan can remove from flywheel at any time, preserves stand-by.
The utility model is simple in structure, and mounting or dismounting are convenient, and are safe and reliable, durable in use, and applied range, are a kind of desirable Simple fans.
Claims (2)
1, a kind ofly be suitable for being installed in the Impeller fan that mechanically operator is carried out pectinid with rotation motion, be made up of blade 1 and wheel hub 2 two-part, it is characterized in that: blade 1 is distributed in wheel hub 2 outer gardens on week, and blade 1 and wheel hub 2 are all made by elastic material.
2, Impeller fan according to claim 1 is characterized in that: be distributed in wheel hub 2 blades 1 of outer garden on week, and identical with helix angle that shaft axis becomes.
