Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Referring to "embodiments" or "embodiment manners" herein means that specific features, structures or characteristics described in connection with the embodiments or embodiment manners may be included in at least one embodiment of the present invention. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0036] As a commonly used component in the water circuit, by controlling the solenoid valve, automatic water intake and water replenishment of the water-using device can be achieved. However, if precise water intake is required, a separate flow meter needs to be added. Currently, the above-mentioned solutions are adopted in the related technologies, but this will make the volume of the water-using device relatively large, and the cost is also relatively high, and it is inconvenient to install.

[0037] Please refer to Figure 1 、 Figure 2 and Figure 9 The present invention provides a solenoid valve 100, including: the solenoid valve 100 includes a valve body 10, the valve body 10 has a first pipeline 11 and a second pipeline 12, and a flow component 20 is arranged on the first pipeline 11 and / or the second pipeline 12;

[0038] The flow component 20 includes: a bracket 30, an impeller 40, and a sensor 60; the bracket 30 is disposed in the first pipe 11 and / or the second pipe 12, the impeller 40 is disposed on the bracket 30, the impeller 40 has a plurality of blades 41, and a cross-section of each blade 41 forms an angle α with the pipe diameter of the first pipe 11 or the second pipe 12; the sensor 60 is disposed on the solenoid valve 100, and the sensor 60 is used to detect the rotation of the blade 41.

[0039] The above solenoid valve 100 counts the water flow rate flowing through the solenoid valve 100 by arranging the flow component 20 in the first pipe 11 and / or the second pipe 12 of the solenoid valve 100. Specifically, by arranging the impeller 40 in the pipe, when the water flow passes through the impeller 40, it pushes the impeller 40 to rotate. When the impeller 40 rotates and is at the same position as the sensor 60, the sensor 60 can receive an electrical signal to determine the number of rotations of the impeller 40. The water flow rate flowing through the solenoid valve 100 is determined by the number of rotations of the impeller 40 to achieve the statistics of the water flow rate; the flow component 20 in the solenoid valve 100 of the present utility model can achieve the statistics of the water flow rate, which can reduce the cost of achieving accurate water intake. It is no longer necessary to install a flow meter on the corresponding pipeline after installing the solenoid valve 10, which can also save the time required for installation and thus improve the work efficiency.

[0040] It can be understood that the first pipe 11 of the solenoid valve 100 can be an inlet or an outlet, and the second pipe 12 can also be an inlet or an outlet. The first pipe 11 and the second pipe 12 only need to satisfy that one is an inlet and the other is an outlet. The flow component 20 can be disposed in the first pipe 11 or the second pipe 12 (that is, the flow component 20 is selectively disposed in the first pipe 11 or the second pipe 12), or two flow components 20 can be simultaneously disposed in the first pipe 11 and the second pipe 12 respectively. As Figure 1 or Figure 2 shown, in general, setting one flow component 20 can complete the statistics of the water flow rate in the pipeline; setting two can further improve the accuracy of the water flow rate statistics and the water outlet accuracy of the solenoid valve 100.

[0041] It can be understood that the flow component 20 includes a bracket 30. The bracket 30 is fixedly disposed in the first pipe 11. The bracket 30 is used to support and rotate the impeller 40. The impeller 40 has a plurality of blades 41. When the liquid flows, it can drive the blades 41 to rotate, and then drive the impeller 40 to rotate. A sensor 60 is disposed on the pipeline where the flow component 20 is disposed. The sensor 60 is disposed on the side wall of the first pipe 11 and / or the second pipe 12 along the third direction; the above third direction can be any direction capable of receiving the magnetic part 42.

[0042] The sensor 60 can detect the rotation of the impeller 40. After each blade 41 on the impeller 40 rotates, it can correspond to the position of the sensor 60. After the position correspondence, the sensor 60 can obtain an electrical signal once. And the flow rate passing through each time the blade 41 rotates is relatively fixed. The number of rotations of the blade 41 * the flow rate can determine the liquid flow rate passing through.

[0043] It should be particularly noted that since the blade 41 is small, the water flow rate passing through the blade 41 is less affected by the water flow, and thus the influence on the accuracy is also less.

[0044] In some embodiments, the arrangement of the first pipe 11 and the second pipe 12 can be as Figure 1 shown in the figure, or can be as Figure 2 shown in the figure.

[0045] The cross-section of the blade 41 forms an angle α with the axis of the first pipe 11 or the axis of the second pipe 12. Specifically, as Figure 4 shown in the figure, the angle between the cross-section of the blade 41 and the first pipe 11 or the second pipe 12 can affect the accuracy of water flow detection. If the angle α is too large or too small, it will affect the rotation of the blade 41 to a certain extent, and thus affect the accuracy of water flow detection.

[0046] As Figure 4 shown in the figure, in some embodiments, the range of the angle α is 10° ≤ α ≤ 60°

[0047] It can be understood that the degree of the angle α can be 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°. If the angle α is small, when the water flow is small, the water flow is not sufficient to drive the impeller 40 to rotate. Therefore, too small an angle will affect the water flow accuracy of the solenoid valve 100. Similarly, if the angle is too large, it will affect the efficiency of water flow passing through. In order to ensure the accuracy of the solenoid valve 100 and the efficiency of water flow passing through, the angle between the impeller 40 and the axis of the first pipe 11 or the axis of the second pipe 12 is set to 45° to ensure the accuracy of water flow rate detection and the efficiency of water flow passing through.

[0048] Please refer to Figure 3 , in some embodiments, the blade 41 includes a water inlet part 411 and a water outlet part 412. The width cross-section of the water inlet part 411 is smaller than the width cross-section of the water outlet part 412, and the width cross-section of the water inlet part 411 gradually increases towards the width cross-section of the water outlet part 412; with the midpoint of the blade 41 as the boundary, the water inlet part 411 bends along the first direction, and the water outlet part 412 bends along the second direction, and the first direction is opposite to the second direction.

[0049] It can be understood that the water inlet part 411 and the water outlet part 412 of the blade 41 are arranged in sequence along the water flow direction, and the water inlet part 411 is bent in the first direction, and the water outlet part 412 is bent in the second direction, and the first direction and the second direction are opposite. As Figure 6 shown, taking the midpoint of the blade 41 as the boundary, the water inlet part 411 is bent to the left (i.e., the first direction) as shown in Figure 6 shown, and the water outlet part 412 is bent to the right (i.e., the second direction) as shown in Figure 6 shown. That is, the overall shape of the blade 41 is a curved surface, and the curved surface can reduce the resistance of water flow. And since the blade 41 generates power through water flow, and the water flow usually flows from the water inlet part 411 to the water outlet part 412 to drive the fan blade to rotate. The cross-section of the water outlet part 412 being larger than that of the water inlet part 411 can make the pressure of the water outlet part 412 greater than that of the water inlet part 411 when the water flow passes through the blade 41, and then make the blade 41 generate a reaction force. This reaction force will cause the fan blade to rotate, thus realizing the effect of the blade 41 driven by water flow to rotate. The width of the water inlet part 411 increasing towards the width cross-section of the water outlet part 412 can improve the rotation efficiency of the blade 41, make the water flow more efficient when flowing through the blade 41, and at the same time reduce the error of the water flow rate.

[0050] It should be noted that the above-mentioned first direction is the direction from right to left as shown in Figure 6 shown or the X direction as shown in Figure 6 shown, and the second direction is the direction from left to right as shown in Figure 6 shown, or the Y direction as shown in Figure 6 shown.

[0051] Please refer to Figure 8 , in some embodiments, a plurality of the blades 41 and the first pipe 11 or the second pipe 12 form a plurality of flow channels 70, and the flow direction of each flow channel 70 is parallel to the axis of the first pipe 11 and / or the axis of the second pipe 12.

[0052] It can be understood that two adjacent blades 41 cooperate with the pipe wall of the first pipe 11 or the second pipe 12 to divide the inside of the first pipe 11 and the second pipe 12 into a plurality of flow channels 70, and the flow rate of each flow channel 70 is the same. Dividing the inside of the pipe into a plurality of flow channels 70 can enable each flow channel 70 to independently transport the flow rate, and can also make the water flow more evenly distributed in the flow channels 70, reducing the situation of local overload or insufficiency in the pipe, and then improving the overall flow rate of the pipe, thereby improving the efficiency of the pipe.

[0053] Please refer to Figure 3 and Figure 4 , in some embodiments, the solenoid valve 100 further includes: a magnetic part 42;

[0054] The magnetic member 42 is disposed on one or more of the blades 41, and the magnetic member 42 is disposed on a side of the blade 41 close to the tube wall of the first conduit 11 and / or on a side of the second conduit 12 close to the tube wall of the second conduit 12;

[0055] The sensor 60 is disposed on the side wall of the first conduit 11 and / or the second conduit 12 along a third direction, and the first direction is perpendicular to the horizontal direction.

[0056] It can be understood that the magnetic member 42 is disposed inside the blade 41, and the magnetic member 42 is disposed on a part of the blade 41 close to the side wall of the first conduit 11 and / or the side wall of the second conduit 12. In other words, the magnetic member 42 is disposed at the distal end of the blade 41, that is, the part close to the side wall of the first conduit 11 and / or the second conduit 12; the sensor 60 is disposed on the side wall of the first conduit 11 and / or the second conduit 12 along a third direction. Of course, the sensor 60 can also be disposed inside the side wall of the first conduit 11 and / or the second conduit 12 along the first direction. The sensor 60 is disposed corresponding to the magnetic member 42, and the sensor 60 is used to receive the signal of the magnetic member 42. Specifically, when the blade 41 provided with the magnetic member 42 rotates to a position corresponding to the sensor 60, the sensor 60 obtains an electrical signal, so that the number of rotations of the impeller 40 can be counted. When the amount of water flowing through when the blade 41 rotates one week is relatively determined, therefore, the number of rotations of the blade 41 * the amount of water flowing through when the blade 41 rotates one week can be the water output of the solenoid valve 100.

[0057] In some embodiments, when one magnetic member 42 is provided, the magnetic member 42 is disposed on any one of the blades 41; when a plurality of magnetic members 42 are provided, the magnetic members 42 are arranged in an array on the blade 41 with respect to the axis of the first conduit 11 or the axis of the second conduit 12; when the magnetic member 42 rotates to a preset position, the sensor 60 generates a signal.

[0058] It can be understood that one or more magnetic members 42 can be disposed on the blade 41. When one magnetic member 42 is provided, it can be disposed on any one of the blades 41. When one magnetic member 42 is provided, the blade 41 rotates one week (i.e., rotates 360°) and sends an electrical signal to the sensor 60, thereby determining the output water flow rate.

[0059] When multiple magnetic members 42 are provided, the magnetic members 42 are respectively provided on each blade 41, and the magnetic members 42 provided on each blade 41 are arranged in an annular array at the distal end of the blade 41 (i.e., the part close to the side wall of the first pipe 11 and / or the second pipe 12), so that it is convenient for the sensor to receive an electrical signal, thereby improving the detection efficiency of the sensor 60; when multiple magnetic members 42 are provided, the detection accuracy can be improved. Specifically, when one magnetic member 42 is provided, the blade 41 needs to rotate one circle to be detected. If multiple magnetic members 42 are provided, for example, 5 are provided, then when the blade 41 rotates 72°, the sensor 60 can detect an electrical signal once, and the water flow rate of each flow channel 70 is also relatively determined. Therefore, the water flow rate flowing out of the solenoid valve 100 can be determined by multiplying the number of times the sensor 60 detects an electrical signal by the flow rate of each flow channel 70. Compared with the method of providing one, providing multiple electromagnetic members can greatly improve the water flow control accuracy of the solenoid valve 100.

[0060] Please refer to Figure 5 , in some embodiments, the bracket 30 includes a first bracket 31 and a second bracket 32;

[0061] Both the first bracket 31 and the second bracket 32 include a plurality of connecting rods 33. The plurality of connecting rods 33 are arranged in the pipe along the axis of the first pipe 11 and / or the second pipe 12, and both ends of the connecting rod 33 are connected to the side wall of the first pipe 11 and / or the second pipe 12; there is an included angle β between two adjacent connecting rods 33.

[0062] It can be understood that the bracket includes a first bracket 31 and a second bracket 32. The first bracket 31 and the second bracket 32 are respectively arranged in the first pipe 11 and / or the second pipe 12 in sequence along the water flow direction. The first bracket 31 and the second bracket 32 can have a plurality of connecting rods 33 arranged around the axis of the pipe in the first pipe 11 and / or the second pipe 12. The length of the connecting rod 33 is the same as half of the inner diameter of the pipe. The plurality of connecting rods 33 are all fixedly connected to the pipe wall of the first pipe 11 and / or the second pipe 12. An included angle β is formed between every two of the plurality of connecting rods 33. The included angle β affects the number of connecting rods 33. The number of connecting rods 33 should not be too many. If the number of connecting rods 33 is too many, it will affect the water flow. If too few, it may cause the connection of the impeller 40 to be not very stable.

[0063] Please refer to Figure 5 , in some embodiments, the range of the included angle β between two adjacent connecting rods 33 is 72°≤β≤180°.

[0064] It can be understood that the included angle β between two adjacent connecting rods 33 can be 70°, 90°, 120°, 180°, etc. That is, 5, 4, 3, or 2 connecting rods 33 can be arranged in an array with the axis of the first pipe 11 and / or the second pipe 12. The number of connecting rods 33 will affect the magnitude of the water flow and the stability of the fixation of the impeller 40. At least two connecting rods 33 are provided to ensure that the impeller 40 can be limited, and at most 5 are provided to ensure the water flow rate.

[0065] Please refer to Figure 5 and Figure 7 , in some embodiments, it further includes: a base 80;

[0066] Both the first bracket 31 and the second bracket 32 are provided with a base 80. The base 80 is arranged to be connected to the connecting rod 33, and the axis of the base 80 is collinear with the axis of the first pipe 11 and / or the second pipe 12; the impeller 40 has a rotating shaft 43, and the rotating shaft 43 has a connecting portion 431. The connecting portion 431 is located within the base 80, and a rotating member 82 is provided within the base 80. The rotating member 82 is arranged around the outer diameter of the rotating shaft 43.

[0067] It can be understood that the base 80 is arranged on the first bracket 31 and the second bracket 32. The base 80 is for enabling the impeller 40 to still rotate after being fixed to the first bracket 31 and the second bracket 32. Specifically, the base 80 is arranged to be circular, and a recessed portion 81 is provided in the middle part thereof. A rotating member 82 is provided in a part of the recessed portion 81, and both ends of the impeller 40 are provided with a rotating shaft 43. Connecting portions 431 are provided at both ends of the rotating shaft 43. In the installed state, the connecting portion 431 is located within the recessed portion 81. At this time, the connecting portion 431 and the rotating member 82 are in an interference fit. When the water flow drives the impeller 40 to rotate, the rotating member 82 can make the rotation of the impeller 40 smoother; the base 80 is arranged at the central part of the pipe, that is, the axis of the base 80 is collinear with the axis of the first pipe 11 and / or the second pipe 12 to ensure the water flow passing efficiency and the rotation of the blade 41.

[0068] The above rotating member 82 can be a steel ball or other components that can assist the rotation of the impeller 40.

[0069] Please refer to Figure 10 , the present utility model further provides a water using device 200, including: the body 210 of the water using device 200, and the solenoid valve 100 as described above.

[0070] The above water-using device 200 includes the solenoid valve 100 in this solution, which can achieve accurate water intake; the solenoid valve 100 of the above water-using device 200 counts the water flow rate passing through the solenoid valve 100 by setting a flow component 20 in the first pipe 11 and / or the second pipe 12 of the solenoid valve 100. Specifically, an impeller 40 is arranged in the pipe. When the water flow passes through the impeller 40, it pushes the impeller 40 to rotate. When the impeller 40 rotates and is in the same position as the sensor 60, the sensor 60 can receive an electrical signal to determine the number of rotations of the impeller 40. The water flow rate passing through the solenoid valve 100 is determined by the number of rotations of the impeller 40, so as to achieve the statistics of the water flow rate. When the flow meter is arranged in the first pipe 11 and / or the second pipe 12 of the solenoid valve 100, it can also reduce the volume occupied by the flow meter and the solenoid valve 100 in the water-using device 200, and at the same time reduce the installation time required and improve the installation efficiency.

[0071] In some embodiments, the above water-using device 200 can be a water purifier, a water heater, a washing machine, a dishwasher or other water-using devices 200.

Those skilled in the art explicitly and implicitly understand that the embodiments described in the present utility model can be combined with other embodiments. In addition, it should also be understood that the features, structures or characteristics described in each embodiment of the present utility model can be combined arbitrarily without contradiction to form another embodiment that does not depart from the spirit and scope of the technical solution of the present utility model.
