Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

Referring to fig. 1 to 2, the present application provides a flow meter 10 for mounting to an intelligent toilet, which includes a housing 100 and a rotor 200. The housing 100 is provided with a cavity 130 and a water inlet 110 and a water outlet 120 communicating with the cavity 130.

As shown in fig. 2 to 11, in some embodiments, the cavity 130 is substantially cylindrical, the rotating member 200 is adapted to the cavity 130 and rotatably disposed in the cavity 130, and the rotating member 200 can be driven by the water flow in the cavity 130 to rotate relative to the housing 100. Specifically, as shown in fig. 2, the rotating member 200 includes a rotating shaft 210 and a plurality of vanes 220, the vanes 220 are disposed on the outer circumferential surface of the rotating shaft 210 at intervals along the circumferential direction of the rotating shaft 210, the rotating shaft 210 is rotatably connected to the cavity wall of the cavity 130, and the axial direction of the rotating shaft 210 is substantially parallel to the axial direction of the cavity 130. The water inlet 110 is opened on the inner circumferential surface of the cavity 130, and the water outlet 120 is opened on the end surface perpendicular to the rotating shaft 210 in the cavity 130, that is, the direction of the water outlet 120 is parallel to the axial direction of the rotating member 200. The water inlet 110 is oriented tangentially to the inner peripheral surface of the cavity 130, that is, the water inlet direction of the water inlet 110 is opposite to the blades 220 of the rotating member 200, the water flow enters the cavity 130 from the water inlet 110 and then impacts the blades 220 to drive the rotating member 200 to rotate, and the flow meter 10 can calculate the flow rate of the water flow according to the rotating frequency of the rotating member 200.

For example, in the embodiment shown in fig. 3, 4 and 5, the water outlet 120 is designed to be sunk, and the water outlet 120 is formed by the cavity wall of the cavity 130 being concave. When the water flow pushes the rotating member 200 to rotate and approach the water outlet 120, a part of the water flow can be guided to the water outlet 120 in advance, so that the water flow near the water outlet 120 is prevented from continuously impacting the rotating member 200. In other words, the thrust received by the rotation of the rotating member 200 basically comes from the water flow impact force near the water inlet 110, and the water flow can be discharged from the water outlet 120 in time after the rotation of the rotating member 200 is impacted, so that the influence of the same water flow on the rotating member 200 is reduced, the rotating member 200 rotates stably, the measurement accuracy of the flowmeter 10 is improved, and the water flow is more stable. Specifically, in the embodiment shown in fig. 3, 4 and 5, the periphery of the water outlet 120 is rounded. The size of the radius of the fillet is not limited, and the fillet can be adjusted by a user according to actual needs. In other embodiments, the periphery of the water outlet 120 may be chamfered.

As another example, as shown in fig. 6, 7, 8, 9, 10 and 11, in some embodiments, the cavity wall of the cavity 130 is recessed to form a water guide 140, the water guide 140 is spirally arranged along the circumference of the rotating member 200, and the water guide 140 is used for guiding the water flow to the water outlet 120. Specifically, in some of these embodiments, the cross-sectional area of the end of the water conduit 140 near the water outlet 120 is greater than the cross-sectional area of the end of the water conduit 140 away from the water outlet 120.

More specifically, in some of these embodiments, the water conduit 140 is a gradual conduit 140, and the cross-sectional area of the conduit 140 gradually increases in a direction toward the water outlet 120. When water flows from the water inlet 110 to the water outlet 120, the water flow pushes the rotating member 200 to rotate and flow along the circumferential direction of the rotating member 200, part of the water flow can flow into the water guide 140 in advance before flowing to the water outlet 120, and as the water flow is closer to the water outlet 120, the cross-sectional area of the water guide 140 is gradually increased, more water flow can flow into the water guide 140 in advance to flow into the water outlet 120 more quickly, that is, the thrust received by the rotation of the rotating member 200 is basically from the water flow impact force near the water inlet 110 as much as possible, the subsequent influence of the same water flow on the rotating member 200 is further reduced, the rotation stability of the rotating member 200 is improved, and the measurement accuracy of the flowmeter 10 is further improved. For example, as shown in fig. 6 and 7, in some embodiments, the bottom of the water conduit 140 is stepped in multiple steps. For another example, as shown in fig. 8, 9 and 10, the bottom of the water conduit 140 is sloped and the slope smoothly transitions to the water outlet 120. Wherein, the bottom of the water guide 140 can be regarded as the side of the water guide 140 far away from the rotating member 200. It should be noted that the spiral length of the water guide 140 can be flexibly adjusted according to actual needs, such as the water guide 140 shown in fig. 9 is longer, and the water guide 140 shown in fig. 10 is shorter.

Referring again to fig. 7 and 11, in some embodiments, the water outlet 120 is a non-circular water outlet 120. Such an arrangement prevents the water from forming a vortex at the water outlet 120, which could affect the rotation of the rotary member 200. The non-circular outlet 120 may be considered as the outlet 120 having a cross-sectional profile of any shape other than a circle, such as an ellipse shown in fig. 7, or a rectangle, an irregular shape, etc.

In other embodiments, as shown in fig. 11, the inner wall of the water outlet 120 is further provided with a rib 150. Such an arrangement can prevent the water flow from forming a vortex at the water outlet 120, which may affect the rotation of the rotating member 200. Specifically, in some embodiments, the rib 150 is provided in plural, and the plural ribs 150 are arranged in a cross manner at the water outlet 120. For example, as shown in fig. 11, two ribs 150 are disposed crosswise at the water outlet 120.

Referring again to fig. 1, in some embodiments, the flowmeter 10 further includes a sensor 300 disposed in the housing 100, wherein the sensor 300 is configured to detect a rotational speed of the rotor 200. Specifically, the sensor 300 may be a hall sensor 300, and at least a part of the structure of the rotation member 200 is magnetic, for example, the vane 220 is magnetic, so that the hall sensor 300 can detect the rotation frequency of the rotation member 200 during the rotation of the rotation member 200.

Referring again to fig. 2, in some embodiments, the water inlet 110 is vertically lower than the water outlet 120. The position of the water inlet 110 is not higher than the position of the water outlet 120, so that the water flowing into the cavity 130 from the water inlet 110 is not easy to flow out from the water outlet 120 due to the gravity, thereby reducing the loss of the kinetic energy of the fluid, in other words, the fluid flowing into the cavity from the water inlet 110 needs to flow out from the water outlet 120 through the rotating member 200 to drive the rotating member 200 to rotate.

Furthermore, in some embodiments, the present application also relates to an intelligent toilet (not shown) comprising a main body and the flow meter 10 according to any of the above embodiments, wherein the flow meter 10 is disposed in the intelligent toilet. For example, in some embodiments, the toilet further includes a spray gun for cleaning and a heater for heating water, and the spray gun is used for spraying a water flow heated by the heater so as to clean a part of the user. The flow meter 10 is applied to a heater, the water outlet 120 is in butt joint with a water inlet channel of the heater, and the flow meter 10 is used for measuring the flow rate of water entering the heater.

According to the above technical scheme, the utility model provides a flowmeter 10 on intelligent closestool, rivers can flow into cavity 130 and flow to delivery port 120 from its water inlet 110 to drive at this in-process and rotate piece 200 and rotate, flowmeter 10 can calculate the flow of rivers according to the rotational frequency who rotates piece 200. The water outlet 120 is designed to be sunk, so that when the water flow pushes the rotating member 200 to rotate and is close to the water outlet 120, part of the water flow can be guided to the water outlet 120 in advance, the water flow close to the water outlet 120 can be guided out in time, and the impact of the water flow on the rotating member 200 is reduced. In other words, the thrust received by the rotation of the rotating member 200 is substantially from the water flow impact force near the water inlet 110, and the water flow can be discharged from the water outlet 120 in time after the rotation of the impact rotating member 200, so as to reduce the influence of the same water flow on the rotating member 200, prevent the water flow near the water outlet 120 from continuously impacting the rotating member 200, facilitate the stable rotation of the rotating member 200, and improve the measurement accuracy of the flow meter 10.
