Abstract
The utility model relates to a hot air gun fan with double turbines, which is used for a hot air gun and provides an internal turbine vane arranged in the center of external turbine vanes of a base plate at the same side of the hot air gun fan. The utility model has the advantages that the structure is simple, the assembly is convenient, the air output is increased by changing the negative pressure into the positive pressure in the center of the fan in operation, the mechanical strength is promoted, the vibration and the noise are reduced, the service life is prolonged and the security of use is good.
Description
Technical field
The utility model relates to the heat gun of electronics, electrician, packaging industry and Laboratory Production, maintenance usefulness, the fan of the heat gun of more specifically saying so.
Background technique
Heat gun development so far, its simple, convenient carrying is changeed heat, experimental ware drying etc. and is widely used carrying out collapsible tube backheat, object fusion, paint removal, shrink wrapping, softening sheet, liquid.Because be no fiery high temperature heating, safety in utilization further improves, the utilization scope is more and more wider, is subjected to people's welcome deeply.Existing commercially available heat gun, its fan are to adopt single group turbine blade form, utilize the centrifugal action of turbine blade that wind directly is depressed into blowing mouth, and the center of fan is to utilize negative pressure that wind is sucked in, and this fan structure is simple, and is easy for installation.But when fan work, can produce vibration and send noise, and the insufficient strength of fan, to damage easily, the life-span is shorter, directly influences the Safety performance of the use of heat gun, has increased maintenance cost, and has incured loss through delay production time and progress.When heat gun is worked, the air output deficiency.
Summary of the invention
The purpose of this utility model provides a kind of heat gun fan with two group turbine blades, it is simple in structure, easy for installation, make that the center of fan transfers malleation to by negative pressure in the work, increase air output, the mechanical strength height of two groups of turbofan, reduce vibration and reduce noise, improve the life-span, safety in utilization is good.
Technical solution of the present utility model is that on the basis of the substrate that has the heat gun fan now, turbine blade, the utility model is that the central position in the outer turbine blade group of substrate ipsilateral is provided with turbine blade in a group.
Turbine blade has two at least in above-described.
Interior turbine blade described in the utility model and substrate are the integral body that one processes, or the fixed bed of tackiness agent is arranged between interior turbine blade and the substrate, or interior turbine blade and substrate are fixed with screw.
Turbine blade distributes along substrate center's radial direction in above-described.
Turbine blade curved arc shape shape is close with outer turbine blade in described in the utility model.
The utility model has the advantages that simple in structurely, easy for installation, make that the center of fan transfers malleation to by negative pressure in the work, increased air output, improved mechanical strength, reduce vibration and reduce noise, improve the life-span, safety in utilization is good.
