Specific embodiment

Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention In attached drawing, the technical solution in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is The embodiment that one end of the present invention is divided embodiment rather than held entirely.Based on the embodiments of the present invention, those of ordinary skill in the art All other embodiments obtained without creative efforts shall fall within the protection scope of the present invention.

It is as shown in Figure 1 it is a kind of can abundant heat gas electric heater, including heating tube 1, heating tube 1, which is internally provided with, to be added Hot pin 8,1 one end of heating tube are equipped with air inlet 2, and the other end is equipped with gas outlet 3, further includes erecting device and guiding device, such as Fig. 2 Shown, erecting device includes restraint zone 4 and fastening bolt 5, and 1 outer surface of heating tube is provided with the binding groove of annular, and restraint zone 4 curves Annular shape, and be socketed in binding groove, 4 beginning of restraint zone is provided with threaded hole, and end is provided with through-hole, and the diameter of through-hole is more than fastening The outer diameter of bolt 5, fastening bolt 5 are threadedly coupled across through-hole with threaded hole, and 5 end of fastening bolt is fixedly connected with baffle 6, gear Plate 6 is plectane, has a diameter larger than the outer diameter of threaded hole, can prevent fastening bolt 5 from excessively being rotated, so that come off, restraint zone 4 On be fixedly connected with fixed plate 7, fixed plate 7 can be connected with corresponding supporting surface, realize heating tube 1 installation and adjustment, in addition, It, should be at least provided with 2 restraint zones 4 in heating tube 1 in view of fastening effect.

As shown in Figure 3 and Figure 4, guiding device includes deflector 9 and hush pipe 10, the air flue inside heating tube 1 including into Wind chamber, contraction chamber 101, adapter cavity 102, diffusion chamber 103 and air-out chamber, air-inlet cavity, adapter cavity 102 and air-out chamber are cylinder Hole, and the internal diameter of adapter cavity 102 is less than air-inlet cavity and the internal diameter of air-out chamber, and contraction chamber 101 connects air-inlet cavity and adapter cavity 102, diffusion chamber 103 connects adapter cavity 102 and air-out chamber, and the length of contraction chamber 101 is more than the length of diffusion chamber 103, heating tube 1 Hush pipe 10 is internally provided with, the side view of hush pipe 10 is identical with the air flue shape of heating tube 1, is wound with and leads on hush pipe 10 Flowing plate 9, and 9 thickness of deflector inside and outside hush pipe 10 is identical, and deflector 9 is spiral plate, and fixes and connect with heating tube 1 It connects, bloop is provided on hush pipe 10.

The operation principle of the present invention is as follows：When installing electric heater, can by adjusting fixed plate 7 position be applicable in The demand of different installation environments first unscrews fastening bolt 5, then rotational fastener band 4, realizes the position adjustment of fixed plate 7, adjusts After the completion of whole, then fastening bolt 5 is tightened, since 4 beginning of restraint zone is provided with threaded hole, end is provided with through-hole, therefore fastening bolt 5 It when tightening, can move horizontally, restraint zone 4 then be squeezed, so as to fulfill the fixation of electric heater；When being heated to gas, gas Enter from the air inlet 2 of heating tube 1, then in turn through air-inlet cavity, contraction chamber 101, adapter cavity 102, diffusion chamber 103 and outlet air Chamber finally leaves from gas outlet, while deflector 9 is equipped in the air flue inside heating tube 1, and deflector 9 is helical form, therefore meeting The air flue that gas forms a spiral in heating tube 1 is guided, compared to traditional straight air flue, increases the flowing road of gas Journey also increases the heating time of gas, so as to improve heating effect, due to the limitation of deflector 9 so that internal gas Flow velocity can decline, therefore do further improvement again for air flue, and there is provided contraction chamber 101, adapter cavity 102, diffusion chambers 103, when flowing through contraction chamber 101, sectional area constantly reduces, by fluid mechanics principle it is found that reduced cross-sectional area, can cause flow velocity to increase Greatly, therefore the speed loss that part is generated by deflector 9 can be balanced out, then in adapter cavity 102, or else speed is broken and reduced, most Afterwards by gas outlet, the internal hush pipe 10 set can mitigate the noise generated during gas stream flow.

The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments The present invention is described in detail, it will be understood by those of ordinary skill in the art that：It still can be to aforementioned each implementation Technical solution recorded in example modifies or technical characteristic is divided its middle-end to carry out equivalent replacement；And these modification or It replaces, the spirit and scope for various embodiments of the present invention technical solution that it does not separate the essence of the corresponding technical solution.
