In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

For a further understanding of the contents, features and effects of the present invention, the following examples are illustrated in the accompanying drawings and described in the following detailed description:

referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic structural diagram of a ball 14-type flowmeter according to an embodiment of the present invention; fig. 2 is a schematic structural diagram of the housing 11 according to the embodiment of the present invention; fig. 3 is a schematic structural diagram of the bottom case 111 according to an embodiment of the invention. As shown in the drawings, the ball 14 type flowmeter of the present application includes a housing 11, an inlet pipe 12, an outlet pipe 13, a ball 14, and a detection assembly 15. The housing 11 is made of a transparent material. The housing 11 has a return passage 110 therein. The water inlet pipe 12 and the water outlet pipe 13 are both communicated with the rotary channel 110. The balls 14 are disposed in the swivel channel 110. The detecting assembly 15 is disposed on the housing 11, and the detecting assembly 15 is located on a moving path of the ball 14. In a specific application, the ball 14 may be made of stainless steel or ceramic, but of course, other materials may be selected according to actual requirements, and the above is only one embodiment of the present invention, and should not be limited thereto.

Further, the housing 11 includes a bottom shell 111 and an upper cover 112, the upper cover 112 is disposed on the bottom shell 111, and the housing 11 is divided into the bottom shell 111 and the upper cover 112, so that the balls 14 can be conveniently placed inside the housing 11, and the mounting and dismounting are convenient. In this embodiment, the water outlet pipe 13 is disposed on the upper cover 112, and the water inlet pipe 12 and the water outlet pipe 13 are perpendicular to each other, so that smooth flow of fluid can be ensured. It should be noted that the diameter of the ball 14 is larger than the inner diameters of the inlet pipe 12 and the outlet pipe 13, so as to prevent the ball 14 from being flushed out of the inlet pipe 12 or the outlet pipe 13 under the pressure of the fluid.

Preferably, the inner diameter of the inlet pipe 12 near the side of the rotary passage 110 is smaller than the inner diameter of the inlet pipe 12 far from the side of the rotary passage 110, so that the fluid is squeezed when flowing from the inlet pipe 12 with a large inner diameter to the inlet pipe 12 with a small inner diameter, increasing the pressure of the fluid and ensuring that the fluid pushes the balls 14 to make a circular motion.

Referring to fig. 4, 5 and 6, fig. 4 is a schematic structural diagram of the detecting assembly 15 according to an embodiment of the present invention; FIG. 5 is a schematic view of another structure of the detecting assembly 15 according to the embodiment of the present invention; fig. 6 is a cross-sectional view of the sensing assembly 15 in an embodiment of the present invention. As shown, the detecting assembly 15 includes a mounting bracket 151, an emitting member 152, a receiving member 153, and a PCB board 154. The mounting bracket 151 includes a first mounting portion 1511 and a second mounting portion 1512, the first mounting portion 1511 and the second mounting portion 1512 are disposed opposite to each other, the first mounting portion 1511 and the second mounting portion 1512 both have a mounting ring 1510, and the mounting ring 1510 and the mounting hole 1100 in the middle of the housing 11 can be connected by bolts. The emitting element 152 and the receiving element 153 are respectively inserted into the first mounting portion 1511 and the second mounting portion 1512, and the emitting element 152 and the receiving element 153 are located at two sides of the housing 11. The PCB 154 is disposed on the mounting frame 151, and the PCB 154 is electrically connected to the emitting element 152 and the receiving element 153.

Preferably, the first mounting portion 1511 has a protrusion 15111, the second mounting portion 1512 has a groove 15121, and when the mounting bracket 151 is disposed on the housing 11, the protrusion 15111 is inserted into the groove 15121, so that the positions of the emitting element 152 and the receiving element 153 can be ensured to be relatively stable, and the deviation between the emitting element 152 and the receiving element 153 during use can be avoided from affecting the detection result. It should be noted that the mounting frame 151 can rotate relative to the housing 11, so as to be adaptable to various mounting positions and convenient to adjust and use.

In a specific application, fluid enters the inside of the housing 11 through the water inlet pipe 12, the fluid pushes the ball 14 to make a circular motion along the rotary channel 110, light emitted by the emitting element 152 is emitted into the rotary channel 110, when the fluid is between the emitting element 152 and the receiving element 153, the receiving element 153 can receive the light emitted by the emitting element 152, when the ball 14 is between the emitting element 152 and the receiving element 153, the receiving element 153 cannot receive the light emitted by the emitting element 152, the time of one circle of circular motion of the ball 14 is obtained through the time when the receiving element 153 cannot receive the light emitted by the emitting element 152 every time, and then the flow rate is calculated through the PCB 154.

In summary, in one or more embodiments of the present invention, the ball-type flow meter detects the moving speed of the ball through the detection assembly, and obtains the flow rate through calculation, so as to greatly reduce friction, ensure the operation precision and the measurement accuracy compared with the existing impeller flow meter.
