As an improved specific embodiment, the flow velocity detection device 3 includes a target ball 33 , a launching device 31 and an induction device 32 that are relatively disposed on the pipe wall of the circulation pipe 1 , and the target ball 33 is disposed in the launching device 31 . , the induction device 32 is coupled with the controller 2, when the flow rate is detected, the launch device 31 launches the target ball 33 to the induction device 32, and the induction device 32 senses the target ball 33 and then outputs the flow rate data to the controller 2, When the flow rate is detected, the launching device 31 launches the target ball 33 to the sensing device 32, and the sensing device 32 senses the target ball 33 and outputs the flow rate data to the controller 2. In the process of using the flowmeter of this embodiment, firstly Connect the circulation pipe 1 to the liquid pipe that needs to measure the flow rate, and then energize the controller 2, the launching device 31 and the sensing device 32, so that during the detection process, the target ball 33 in it is launched through the launching device 31, The target ball 33 will pass through the liquid to reach the sensing device 32, and due to the existence of the liquid flow rate, there will be a deviation between the position where the target ball 33 reaches the sensing device 32 and the position where there is no liquid flow velocity, so by calculating the magnitude of this deviation, The acceleration of the target ball 33 can be effectively calculated equivalently, and then the impact force of the liquid on the target ball 33 can be calculated through the acceleration, and then according to the relationship between the liquid flow rate and the impact force, the liquid flow rate can be effectively calculated. Therefore, compared with the flow meter in the prior art, the liquid does not need to be limited to a conductive liquid, and there is no problem that a fixed obstacle hinders the flow of the liquid, and the target ball 33 is not easily affected by the liquid during the movement. effects of tiny particles.

As an improved specific embodiment, the launch device 31 includes a launch pipe 311 and a launch mechanism 312 disposed in the launch pipe 311 , the launch pipe 311 is closed at one end, and the other end is fixed on the pipe wall of the circulation pipe 1 It is connected to the inside of the circulation pipe 1. When launching, the launching mechanism 312 launches the target ball 33 from the launch pipe 311 into the circulation pipe 1. The setting of the launch pipe 311 can effectively provide the target ball 33 with a launch The guiding structure ensures that the speed and direction of the target ball 33 entering the circulation pipe 1 are stable, thus further increasing the accuracy of the detection of the liquid flow rate.

As an improved specific embodiment, the launching mechanism 312 includes a reset motor 3122 fixed on the end of the closed end of the launch pipe 311 and an elastic launch film 3121 covering the end surface of the open end of the launch pipe 311.

One end of the reset rope is fixed on the rotating shaft of the reset motor 3122, and the other end is connected to the elastic emission film 3121, and is fixedly connected to the target ball 33 through the elastic emission film 3121. When the launch mechanism 312 is in standby, the rotating shaft of the reset motor 3122 is wound with the reset rope, and the target ball 33 is pulled toward the reset motor 3122 to move to the longest position, so the target ball 33 also pulls the elastic launch film 3121, and so on The elastic launch film 3121 will deform and accumulate elastic force, and when the target ball 33 is launched, it is only necessary to reverse the rotation of the rotating shaft of the reset motor 3122 to continuously loosen the reset rope, so that the target ball 33 will be elastically launched The film 3121 enters into the circulation pipe 1 under the elastic force of the film 3121. Since the elastic launch film 3121 covers the end face of the open end of the launch pipe 311, when the elastic launch film 3121 is reset to its original state, the target ball 33 just reaches the launch pipe. The exit of 311, so the target ball 33 will obtain an initial velocity. Since the reset rope and the elastic emitting film 3121 in this embodiment are not fixed, but only pass through, the reset rope will be connected to the elastic emitting film 3121. It is slidable in between, so the target ball 33 continues to move towards the induction device 32 under the action of inertia, so that a launch effect is effectively achieved, and through the effect of the rotation of the rotating shaft of the reset motor 3122, the target ball 33 is pulled to reset, In this way, the effect of multiple detections can be achieved, and the detection accuracy can be further increased. The rotation speed of the reset motor 3122 in this embodiment can be set to be gradually accelerated, and the acceleration of the acceleration is slightly greater than that generated by the elastic emission film 3121 for the target ball. In this way, the problem that the target ball 33 will be pulled by the reset rope during the launching process and the problem that the reset rope is reversely wound due to the too fast rotation of the reset motor 3122 can be avoided.

When the target ball 33 is hit on the pressure sensing bar 321, the pressure sensing bar 321 outputs the position signal of the target ball 33 to the controller. 2, for the controller 2 to calculate the current flow rate, through the setting of the pressure sensing bar 321, it can be effectively realized that when the target ball 33 reaches the pressure sensing bar 321, the current position hit by the target ball 33 can be effectively detected. , so that the controller 2 can calculate the current flow rate effectively. Since the target ball 33 will have a certain impact force when it reaches the pressure sensing bar 321, it can be effectively determined that the pressure sensing bar 321 can detect the arrival position of the target ball 33. , compared with the method of electric induction detection in the prior art, it will not be affected by the conductive liquid.

The groove is a long strip, and several of the buttons are arranged in the groove, and are arranged in a row along the length direction of the groove to form the structure of the induction bar 3212. When the target ball 33 is launched to the induction bar 3212, the target The ball 33 squeezes the button, and the button outputs a signal to the controller 2. Through the setting of several buttons, when the target ball 33 reaches the pressure sensing bar 321, the button will be affected by the impact force of the target ball 33. Pressing down, the signal will be output to the controller 2, so the controller 2 in this embodiment can store the distance value corresponding to the button one-to-one, that is, when which button is pressed, the target will be determined. The deviation distance of the ball 33 is the distance value corresponding to the button, and when two or more buttons are pressed, the distance value of the pressed button is extracted, and then the average value is calculated as the deviation distance of the target ball 33, Therefore, in this embodiment, if enough buttons are set, the corresponding precision will be higher, so that the effect of detecting the arrival position of the target ball 33 is well realized, and only the average number needs to be calculated in the process of detection and calculation. Yes, so the calculation process is also simple and convenient, which greatly reduces the complexity of the calculation algorithm and increases the operation speed of the controller 2 .

To sum up, the flowmeter structure of this embodiment can effectively realize the use of magnetic force when the controller 2 does not need to be taken by the cooperation of the placement slot 111 , the trigger switch 22 , the electromagnet 21 and the magnet 112 . Fixed, when the controller 2 needs to be taken, the controller 2 is ejected by magnetic force, thereby realizing the effect of being convenient for the controller 2 to take and view.
