Description of the creation: [New technical field] This creation department (4) "Improved structure of turbine money fan", especially when the turbine inlet or outlet end is blocked, its power consumption will be The blade that automatically lowers the yak, which in turn reduces the motor load. [Prior Art] According to 'Please refer to the seventh figure, there are several radial arrangements between the main circular bottom plate a and the top plate a/ of the turbine of the conventional turbo blower, and the b-shaped guide b' Extending outward from the center of the bottom plate a by a radial arc to the outer edge of the bottom plate a, the leaf=end bi of the guide vane b is located near the center of the bottom plate a, and the guide vane is front end of the baffle Bl gradually descends to the lowest point of the blade rear end b2 and then the outer horizontal extension curve; the blade turbine is disposed in the gas collecting hood c, and the servo-motor d directly or indirectly drives the rotation; the gas gathering (four) has: The intake port and the exhaust gas π c2, the air inlet port c is correspondingly arranged in the turbine (the upper part of the turn) and the corresponding one of the 0^1 'exhaust port 2 on the top plate a/ of the turbine is provided. The air is sucked by the air inlet c1 and then discharged by the air outlet c2 on the outer side and the edge of the turbine. According to the above configuration, when the full wheel is driven by a motor, the blade of the guide vane b is rotated at a high speed. The front end bl causes the center point to form a cylindrical chamber, and the cylindrical space is a vacuum-like negative pressure. Putting the outer empty money into the intake air n cl, and then pushing the air sucked along the guide vane (4) toward the outer edge of the rear end b2 of the tea piece, and passing through the extrusion of the blade rear end 1 of the guide vane b The airflow at this point forms positive pressure air, which can be exhausted by the exhaust port C2. 5 M3 01945 The turbine of the Baizhi turbine blower has a lower height (ie, wind) due to the blade rear end b2 of the guide vane. The cutting action area is small, and the positive pressure of the exhaust gas is insufficient, and the conventional design is unreasonable. It is still acceptable, or can be used in the inhalation and exhaust. Where it is required, such as a vacuum cleaner or a simple daily appliance for a blast furnace, but it is not applicable when high pressure gas is required; and the conventional turbine structure is blocked when ^ =:Cl or one end of the exhaust port C2 Two; the shape of Han negative pressure and positive pressure value is very large, leading to the drive of the turbine rotation = force: multiple growth, and easy to increase the motor load, and even the motor will be burned out. [Content] Lost, 2 Creation, the above-mentioned conventional turbine blade structure design is not The lack of "month ~ research nine, and accumulated personal experience in this business for many years, wants to not count a new salary of the "turbine blower improved structure." ~ The main purpose of this creation, & _ good structure, It is recommended that (4) the turbine blower that can effectively control the flow of the turbine by the correction of the turbo blower, and the turbine blower that can reduce the motor load. The main purpose of the project is "Improved structure of the turbine blower" The main feature is that the front end of the guide vane is gradually reduced to one 2 = from any of the front end of the blade near the center of the bottom plate to any of the relatively low points: the same 'and then gradually increased from the relatively low point: again The shape of the circular area formed by the phase is added. The blade rain is added to the curve of the back end of the blade. The m structure is created. The original structure of the turbine blower is provided with a plurality of guide vanes between the _ and the top plate =: The vortex M3 01945 wheel train is set in the 隹 _ trade + = in the wood rolling hood, the gas collecting hood has an air inlet and a: two air inlets corresponding to the circular hole in the central part of the turbine top plate Piece ί= corresponds to the turbine The outer edge of the outer edge; because of its conductance: = the height is higher', so when the turbine rotates at a high speed, the medium:: the area of action of the slap air is larger, and the lowering point is made by the guide vane The thrust to the rear end of the blade is increased, so that the positive pressure (discharge amount) of the exhaust region at the rear end of the blade is relatively increased, and ς, good air compression efficiency (and large displacement); When the turbine is blocked on the side of the air outlet, the air formed at the rear end of the blade is guided to the cylindrical space of the front end of the blade of the turbine, and the negative pressure of the air is The positive pressure is opposite to the point that the power consumption of the turbine is not increased and decreased, so that the effect of reducing the motor load can be achieved. [Embodiment] In order to enable the reviewing committee to have a more in-depth understanding and understanding of the structure, device and features of the creation, a feasible example is given and explained as follows: First, please refer to the first to As shown in the third figure, the "improved structure of the turbo blower" of the present invention is mainly provided with a plurality of guide vanes 2 between a circular bottom plate and a sheet metal plant, and the guide vanes 2 are close to the center of the bottom plate. Extending outwardly from a radial arc to the outer edge of the bottom plate i, and being disposed in a collection cowl 3, the air collection hood 3 has an air inlet 31 and an exhaust port 32, respectively. The inlet 31 of the sea corresponds to the upper hole of the central part of the thirst wheel roofing plant, and the exhaust port 32 corresponds to the outer edge of the turbine; the feature is that the height of the guide vane 2 is close to the center of the bottom plate The leading end 20 of the blade begins to gradually decrease to a relatively low point 22 of a mid-section where the cross-sectional height of the blade at any position between the M3 01945 w-end and the relatively low point is the same. The relative low point 22 of the hai gradually increases the blade height to the curved shape of the trailing end 21 of the blade. Please refer to the fourth figure again. The design principle of the front end of the vane 2 of the guide vane 2 to the center of the bottom plate 1 is a constant of the circumferential area of the cylindrical space formed by the rotation of the vane 2. For example: Fake 5 and the height 11 of the front end of the blade to the bottom plate is 11〇〇cm (may be needed and more) and the distance R from the front end 2〇 of the blade to the center point of the bottom plate 1 is 4 0 cm, the circumferential area (7rdh) of the cylindrical space formed when the front end of the blade is rotated by 2 等于 is equal to 31416cffl2; and, at any point (1) between the front end 20 of the blade and the relatively low point 22, The area value of the temple (31416 cm 2), if the distance from the child's point (X) to the center point of the floor is π(10), then the height of the point is h, 416 cm V (r *150) 667 (10) That is, at any point between the front end 2〇 of the guide vane 2 and the relatively low 'point 22=cut, the circumferential area formed by the height is equal, and can also be obtained at the front end 20 of the piece due to the rotation of the turbine. Fixed air vacuum suction. Basin 2":; ΠΤΐ blade front end 20 (negative Lili) or blade rear end ^ 卩 and base time 'the driving power of the thirsty wheel will be multiples 々 =, resulting in power loss or damage to the mechanism; The change in the shape of the hunting guide vane 2 is to progressively increase the blade height after the blade low point 22 to the blade rear end 21 (the gas row of the pressure portion formed between the low point 22 and the blade rear end 21 of the involute curve) The pressure is increased, and the gas attraction (negative) of the * lead portion between the front end 2 〇 and the relatively low point 22 is kept constant, so that the pressure and the attraction force of the pressure M301945 and the guiding portion cancel each other. Reducing the learning gap between them, the power consumption of the turbine will gradually decrease. According to the experiment, when the motor is driven by a 5HP motor, the current in the normal state is i5a; the air intake of the /13⁄4 turbine When the mouth or / and the air outlet are blocked, the current on the three-meter meter does not increase or decrease, but gradually decreases to about 5~3A), thereby achieving the effect of reducing the motor load. As in the above configuration, the same or similar blower configuration may be used in series in the implementation of the present invention (as shown in the fifth and sixth figures); the fifth figure includes the - primary turbine 51, - times The stage turbine 52 and a collector hood 53' and the primary turbine 51 in the #@ diameter are smaller than the secondary wheel to cause the suction from the primary inlet 531 to be less attractive than the secondary inlet (also the primary vent) 532 Then force 'can increase the pressure of the blower row/inhalation and the effect of using it more step by step; and so on, it can also be used as a secondary or higher use type. Similarly, in the sixth figure, the blade height of the secondary turbine is greater than the blade height of the primary turbine 61, so that the initial attraction of the collector hood = the inlet 631 is less attractive than the secondary inlet (also The primary exhaust is called the attraction of 632, which aims to increase the blower row and the suction pressure. In summary, the creation of the "turbine blower improved structure" can achieve the mechanical efficiency of the turbo blower = Efficacy, but with the "practicality" and "progressiveness" of creation, and the following: The creation of a special shot is not seen in the publication or the public use of m, ^ can conform to the new patent requirements, and the patent is filed according to law.
