Fig. 5 is a schematic diagram of the flowmeter 200 of fig. 1. Fig. 6 is a schematic cross-sectional view of the structure of part a in fig. 1. As shown in fig. 5 and 6, the flow meter 200 in the present embodiment is a hall flow meter or an ultrasonic flow meter, and other types of photoelectric flow meters can be used instead of the conventional reed pipe flow meter. Compared with the traditional reed pipe type flowmeter, the Hall flowmeter or the ultrasonic flowmeter has the advantages of low failure rate, low water quality requirement, high measurement precision and the like. The flow meter 200 includes a flow meter body 210, and the flow meter body 210 is provided with a first protruding end 220 and a second protruding end 230 arranged toward the respirator body 100. The first extension end 220 is provided with an inflow port 221, and the second extension end 230 is provided with an outflow port 231. The inflow port 221 communicates with the flow dividing port 1236, and the outflow port 231 communicates with the return port 1238, whereby the flow meter 200 detects the inflow rate of water in the water inlet passage 123.

In other embodiments of the present invention, the flow splitting port 1236 and the flow returning port 1238 may be provided on the curved passage section 1233 together, or the flow splitting port 1236 may be provided on the second ascending passage section 1232 and the flow returning port 1238 may be provided on the curved passage section 1233.

Further, in order to facilitate communication between the flow splitting port 1236 and the flow inlet 221 and to facilitate communication between the flow return port 1238 and the flow outlet 231, the respirator housing 100 in which the flow splitting port 1236 is located in the present embodiment is provided with a first cylindrical protrusion 1237, and the respirator housing 100 in which the flow return port 1238 is located is provided with a second cylindrical protrusion 1239. The first protruding end 220 is connected to the respirator housing 100 by plugging into the radially inner wall of the first cylindrical protrusion 1237, and the second protruding end 230 is connected to the respirator housing 100 by plugging into the radially inner wall of the second cylindrical protrusion 1239.

By inserting the first projecting end 220 into the first tubular projection 1237 and inserting the second projecting end 230 into the second tubular projection 1239, the communication between the flow splitting port 1236 and the flow inlet 221 and the communication between the return port 1238 and the flow outlet 231 can be effectively completed.

In other embodiments of the invention, the first protruding end 220 may also be connected to the respirator housing 100 by plugging onto the radially outer wall of a modified first barrel projection, and the second protruding end 230 may be connected to the respirator housing 100 by plugging onto the radially outer wall of a modified second barrel projection. That is, a modified first barrel projection is inserted into the first projecting end 220 and a modified second barrel projection is inserted into the second projecting end 230.

In other embodiments of the present invention, a first annular groove and a second annular groove may be provided in the interior of the respirator housing 100, and the flow-dividing port and the return port may be provided at the bottom of the first annular groove and the second annular groove, respectively.

cylindrical protrusions

1237 and 1239 may not be provided. Instead, the first extended end 220 is inserted into the diversion port 1236 and the second extended end 230 is inserted into the return port 1238. Accordingly, the positions of the inlet 221 and the outlet 231 are also adjusted. The inflow port 221 is formed on a sidewall of the first extension 220 facing the bottom of the first ascending channel 1231, and the outflow port 231 is formed on a sidewall of the second extension 230 facing the top of the second ascending channel 1232, so that the water flows from the first ascending channel 1231 to the second ascending channel 1232.

Further, in order to increase the sealing performance between the first protruding end 220 and the first cylindrical protrusion 1237 and between the second protruding end 230 and the second cylindrical protrusion 1239, both the outer wall surface of the first protruding end 220 and the outer wall surface of the second protruding end 230 are provided with an annular groove 240, and a sealing ring 300 is disposed in the annular groove 240. That is, the sealing ring 300 is provided between the mating surfaces between the first projecting end 220 and the first cylindrical protrusion 1237, and the sealing ring 300 is provided between the mating surfaces between the second projecting end 230 and the second cylindrical protrusion 1239, thereby improving the sealing property.

Further, in order to limit the length of the first and second protruding ends 220 and 230 inserted into the ascending channel segment, and prevent the first and second ascending

channel segments

1231 and 1232 from being reduced in sectional area due to an excessively long insertion depth, and even blocking the first and second ascending

channel segments

1231 and 1232, the respirator housing 100 is further provided with a positioning surface for positioning the insertion depth of the first and second protruding ends 220 and 230. As shown in fig. 5 and 6, the first projecting end 220 and the second projecting end 230 in the present embodiment have the largest outer surfaces of the cylindrical shape, and therefore the inner wall surfaces of the corresponding first cylindrical protrusion 1237 and the second cylindrical protrusion 1239 are also both cylindrical. The flow dividing port 1236 is coaxially disposed with an inner wall surface of the first cylindrical protrusion 1237, and a diameter of the flow dividing port 1236 is smaller than a diameter of the inner wall surface of the first cylindrical protrusion 1237, that is, the diameter of the flow dividing port 1236 is smaller than an outer diameter of the first protruding end 220, so that when the first protruding end 220 is inserted into the inner wall surface of the first cylindrical protrusion 1237, the side plate 122 surrounded by the inner wall surface of the first cylindrical protrusion 1237 forms a positioning surface for positioning the first protruding end 200. The return port 1238 is disposed coaxially with the inner wall surface of the second tubular projection 1239, and the diameter of the return port 1238 is smaller than the diameter of the inner wall surface of the second tubular projection 1239, that is, the diameter of the return port 1238 is smaller than the outer diameter of the second protruding end 230, so that when the second protruding end 230 is inserted into the inner wall surface of the second tubular projection 1239, the side plate 122 surrounded by the inner wall surface of the second tubular projection 1239 forms a positioning surface for positioning the second protruding end 230.

The inner cavity structures of the first tubular protrusion 1237 and the second tubular protrusion 1239 in this embodiment are only one embodiment of the present application, and in other embodiments of the present application, the first protruding end 220 and the second protruding end 230 may have a square shape or other structural forms, and the inner cavity structures of the corresponding first tubular protrusion 1237 and the second tubular protrusion 1239 also have a square shape or other structural forms. Also, the diameter of the branch flow opening 1236 is smaller than the minimum radial dimension of the outer wall of the first protruding end 220, and the diameter of the return flow opening 1238 is smaller than the minimum radial dimension of the outer wall of the second protruding end 230, so that a positioning surface for positioning the first protruding end 220 and the second protruding end 230 is formed by the outer side surface of the side plate 122.
