[Technical field to which the new type belongs] The new type is the main blade that is driven by the liquid flow in the channel to rotate and the main blade is provided with an isolation space above the main blade to accommodate the auxiliary blade, and ^ J pieces and the corresponding ends of the auxiliary blade are A magnet is embedded to enable the two main and auxiliary blades to rotate in sync with each other through the magnetic attraction of the corresponding blades. Photoelectric launchers and receivers are provided above and below the blade ends of the blades. Calculate the flow of liquid through the channel. a [prior art]

The control of the liquid flow rate and flow rate must be completed by the detection unit = structure. Among them, for example, the gas and liquid control control announcement No. 352844 improved structure, which includes the body, the sensor, the sealing cover, and the circuit board. The upper body is composed of 'the body is provided with an entrance, an exit and a recessed accommodation space, and a leak-proof ring is provided on the periphery. The circuit board has a signal output terminal, which can output a control signal to the object to be controlled.' The upper cover is covered by On the body; at the same time, the inlet aperture of the body is smaller than the outlet aperture, and the accommodation space is just the induction body, and a number of blades are arranged on one axis of the induction system. It is rotatable in space; there is another seal cover, which is provided with a convex protruding space, and grooves on both sides, and a transparent area is provided at the corresponding groove for light transmission; The cover set is arranged on the body to form a completely airtight accommodation space; secondly, a circuit board with a light sensor is provided, and the light sensor includes an emitting light source and a component that receives the light source. Cover Slot. However, in the above, the liquid is calculated by using a light sensor including an emitting light source and a light source element to continuously interrupt the light source of the blade, so as to calculate the liquid.

Page 5 M243642 V. Creative Instructions (2) The flow of '------' in actual use has the following shortcomings that need to be improved: that is, when the liquid is colored and does not have light transmission or poor light transmission , It will hinder the role of the light source and the light source's emitting light source and the components that receive the light source, resulting in the inability to effectively or accurately measure the calculated liquid flow, or even lose the role of measurement and calculation.左 # Moreover, the groove in which the light sensor is housed is set as a transparent area for light transmission. Ik is used for a long time. When the scale or dirt generated in the liquid adheres to the inner wall of the groove, it will also cause light. The sensor's emitting light source and the components that receive the light source are out of action ', making it impossible to effectively or accurately measure and calculate the flow rate of the liquid, or even completely lose the role of measurement and calculation. Furthermore, if the measured and calculated fluid is a high-temperature liquid, its high temperature is transmitted to the light source for light emitting and light-transmitting components, which will also shorten its service life. [New content] The reason is that in order to improve the above-mentioned liquid flow sensing errors, inaccuracies, inefficiency, or shortening of the life of the light sensor, the new type is a magnetically stable magnet embedded above the main blade. On the flange part, a magnet with superior magnetic force is further arranged on the flange part of the auxiliary blade in the isolation space corresponding to the space 5 and the main and auxiliary parts are magnetized by the mutual magnetization of the corresponding magnets. The blades do rotate synchronously; therefore, they are not immersed in the wave body because they are isolated from the circulating liquid, so they present an unobstructed space. They also cooperate with the optoelectronic transmitters and receivers located near and below the blades of the auxiliary blades. The calculation of the liquid flow is performed by the intermittent blocking effect of the blade rotation, and the liquid that is not affected by the circulation is colored or turbid liquid, or due to scale and

Page 6 M243642 V. Creative Instructions (3) Dirt will hinder the accuracy of light; it will not be transmitted to those who use light. Secondly, the front blade is not affected by external factors, and if its secondary blades are affected by the main in the liquid, it can also protect the magnet so that the secondary blades of the two will not rotate synchronously. In addition, due to external factors affecting water use, you can get a full understanding of it [for the actual respect, please refer to the section with the main leaf side and the blade with the 2 for the leading side. The shaft part 23, the role of the electric sensor, when the flange of the main blade of the liquid flow sensor element is affected and not easy to rust, the magnet on the blade can keep the magnet on the blade even if it is quite stable. The magnetism can still keep quite stable. The tripping and deceleration speed can make the liquid flow through the high temperature liquid, so it can be added to the light place to be magnetically stable and completely stable with the liquid. It has a strong dirt-covered bag, and cooperates with the auxiliary leaf. The mutual magnetic attraction can be more accurately calculated. Its high temperature is also the fixed magnet of the electric sensor, the magnetic force of the isolated secondary leaf force, and the strong force on the chip over the high temperature can make the main blade follow the main blade. A new type of blade that is not easy to be cleaned can be borrowed, and according to the method] The first and second two-axis and two-axis installation and discharge positions are set above the magnetic stability to make the main leaf flange part bell, if drinking water quality. The following embodiments are implemented in conjunction with the drawings: A magnet with magnetically stable liquid flow sensing is set up, and the device is shown in the figure. The empty space of the new type is a 10, and the lower liquid The entrances and exits 11 and 12 have a flange portion 21 and are convex, and the magnets 2 2 on the shaft portion 23 which are on the main leaf 2 can be lower two of the upper body 1 of the main body 1, and the main blade edge portion 2 1 The end piece 2 runs through idling, then

V. Creation instructions (4) After that, a transparent upper body 3 is fixed above the lower body 1, and the upper and lower spaces are separated by upper and lower spaces 3 1, 3 2 so that the lower space 3 2 can accommodate flanges.部 2 1; At the same time, the upper end of the shaft part 23 is extended into the upper space 3 1, and a pair of blades 4 are set on the vehicle part 2 3 so as to be able to rotate freely. There is a flange portion 41 that can be accommodated in the space 31 above the upper body 3, and a plurality of magnets 4 2 with strong magnetic properties are provided on the end surface of the flange portion 41, and then the end surface of the upper body 3 is covered with a The transparent upper cover 5 allows the blade part of the auxiliary blade 4 to be accommodated in the upper cover 5, and the optoelectronic emission and receiver 6 are provided on the opposite side of the upper cover 5 and the upper body 3 located near the end of the blade of the auxiliary blade 4. 1, 6 2. · The dandan cooperates with the interior space of 10 and rotates from the outlet 12 and the main blade 2 and then rotates synchronously by the mutual movement of the magnet 42 on the flange 41, and the intermittent rotation of the photoelectric 4 Intercept the effect, and then calculate the liquid flow. Therefore, although the magnets 22 in 21 places of the main blade 2 are magnetically stable and clean without being contaminated, and even if the stones 22 or the liquid is high temperature, the flanges 41 of the auxiliary blades 4 can be maintained chemically. Stable and strong magnetic interaction with each other 'causes the pair to show that when the liquid is introduced into and discharged from the inlet 11, the magnetic attraction between the magnet 22 and the auxiliary blade 4 on the part 21 is driven by the flow of the liquid, so that The auxiliary blade 4 can be launched and the receiver 6 1, 6 2 because the auxiliary blade is connected to calculate the rotation speed of the main blade 2 and is immersed in the liquid, but the flange part is not easy to rust, so the liquid can be kept in the liquid. Its dirt is covered with magnetic liquid; it can still maintain stable magnetism, because the strong magnet 42 is not in contact with the liquid: the upper two leaves can be kept quite stable. The 4 pieces can still be synchronized with the main leaf M243642. 5. Creation instructions (5) The blade 2 rotates, so the calculation of the flow rate will not be more stable. Also, please refer to the inverted setting of the main blade 2 and the upper cover 5 again, and the receiver 6 1 and 6 2 are provided on the circumferential surface of the part 41. Set at 43 perforations. Therefore, the main and auxiliary leaves rotate synchronously, and when the two ends are aligned with the photoelectric energy to achieve signal reception, the receivers 61 and 62 make rotation speeds, and the liquid is calculated. The space channel is located in an unobstructed space with translucency, and it will not have any effect, so that although the above disclosure and detailed description are all familiar with various shapes and situations and categories. The second and fourth blades 4 and 4 are launched, used, and then used, and the same flow rate is used in this embodiment, while the secondary blades are used in the same embodiment, so the photoelectricity can be truly implemented. The changes to the technical department have occurred. The phenomenon of shedding speed makes the liquid accurate. As shown in the fourth and fifth figures, the upper and lower bodies 1, 3, and the structure are the same, but the secondary blade 4 is a magnet 42 $ on each secondary blade 4, and the flange has a plurality of through-holes 43. Photoelectric emission, the two sides of the upper cymbal 5, and each of the perforations 43 on the flange portion 41 magnetically attached to each other by the magnets 22, 42 interposed between the flanges 4 workshops, when the closing, 6 1, 6, 2 Between the two, through the perforation 43 intermittently, the photoelectric sampling can be used to indirectly calculate the 0 'of the main blade 2. Because only the main blade 2 is set on the blade 4 and it is not in contact with the liquid, even if the liquid is colored or turbid, it will not shoot. The functions of the receivers 6 1 and 6 2 calculate the accurate liquid flow. Those who have a better embodiment of the new model can clearly understand it, and it ’s all supposed to be without departing from the essence of the new model.
