It should be appreciated that when the first flow meter 150 is another type of flow meter, the detection location of the first flow meter 150 may also vary, and is not limited to an impeller.

In one embodiment of the present utility model, as shown in fig. 3 and 4, the soft water outlet pipe 911 includes a pipe body 912 and a mounting seat 913, the mounting seat 913 is provided at one side of the pipe body 912, the mounting seat 913 is provided with a mounting cavity 9131, the mounting cavity 9131 communicates with the pipe body 912, the first flowmeter 150 is mounted in the mounting cavity 9131, and the first flowmeter 150 is hermetically connected with an inner wall surface of the mounting cavity 9131.

Because the installation cavity 9131 is in communication with the pipe body 912, when the first flowmeter 150 is installed on the installation seat 913, a detection portion of the first flowmeter 150 can be located in the pipe body 912, so that the first flowmeter 150 can detect the water flow in the pipe body 912. The utility model mounts the first flowmeter 150 on the mounting seat 913, which can improve the mounting stability of the first flowmeter 150, and the sealing connection between the first flowmeter 150 and the mounting cavity 9131 can improve the sealing performance between the first flowmeter 150 and the inner wall surface of the mounting cavity 9131, and can prevent the water in the pipeline body 912 from flowing out from the connection part of the first flowmeter 150 and the mounting seat 913.

In an embodiment of the present utility model, the first flow meter 150 is sealingly connected to the inner wall surface of the mounting cavity 9131, for example, by a seal, and the first flow meter 150 is also sealingly connected to the inner wall surface of the mounting cavity 9131 by an interference fit.

In one embodiment of the present utility model, the connection member includes, for example, a clamping block provided on the first flowmeter 150, and an inner wall surface of the installation cavity 9131 is provided with a clamping hole matching the clamping block, and when the first flowmeter 150 is installed in the installation cavity 9131, the clamping block is adapted to be clamped with the clamping hole, so that the first flowmeter 150 and the inner wall surface of the installation cavity 9131 are stably connected together. When the first flowmeter 150 needs to be detached from the mounting seat 913, an external force is applied to the first flowmeter 150, so that the clamping block and the clamping hole are separated, and the first flowmeter 150 can move relative to the mounting cavity 9131, thereby realizing the detachable connection of the first flowmeter 150 and the mounting seat 913.

It should be noted that the connecting member may be any other clamping structure suitable for being clamped with the clamping hole besides the clamping block.

When the first flowmeter 150 needs to be detached from the mounting seat 913, the plug 914 is moved away from the communication structure 9132, so that the plug 914 and the first flowmeter 150 are separated from contact, at this time, the plug 914 does not play a role in fixing the first flowmeter 150, the first flowmeter 150 can move relative to the mounting cavity 9131, and the first flowmeter 150 can be detached from the mounting seat 913.

It is understood that the connection between the plug 914 and the first flow meter 150 may be a snap fit, an interference fit, or any other suitable connection.

In an embodiment of the present utility model, as shown in fig. 3 and 4, the plug 914 includes a plug body 9141 and a first plug portion 9142, the first plug portion 9142 is connected to the plug body 9141, the communication structure 9132 includes a first connection hole 9133, the first plug portion 9142 is disposed through the first connection hole 9133, where the first flowmeter 150 is provided with a first clamping groove 915, and the first plug portion 9142 is clamped to the first clamping groove 915.

For example, the first plugging portion 9142 may be inserted through the first connection hole 9133 and the first clamping groove 915 to be clamped, so that the first flowmeter 150 cannot move, and plays a role in clamping and fixing the first flowmeter 150.

In an embodiment of the present utility model, the first plugging portion 9142 includes an arc structure, the first clamping groove 915 is an arc groove, and the arc of the arc structure is the same as the arc of the arc groove.

For example, when the first plug portion 9142 is inserted into the first connection hole 9133 and is clamped to the first clamping groove 915, the radian of the first plug portion 9142 is the same as that of the first clamping groove 915, so that the portion of the first plug portion 9142 clamped to the first clamping groove 915 can be increased, the first plug portion 9142 can be better clamped to the first clamping groove 915, and the clamping and fixing effect on the first flowmeter 150 is effectively improved.

When the mounting of the first plug portion 9142 is more stable, the fixing effect of the first plug portion 9142 to the first flowmeter 150 can be improved.

In the embodiment of the present utility model, the groove 916 is an arc-shaped groove, the radian of the first plug portion 9142 is the same as the radian of the groove 916, and the first plug portion 9142 can be deformed relative to the plug body 9141.

By way of example, when the first plug portion 9142 is inserted into the first connection hole 9133 and the groove 916, since the radian of the first plug portion 9142 is the same as the radian of the groove 916, the portion of the first plug portion 9142 that is clamped with the groove 916 may be increased, so that the first plug portion 9142 may be better clamped with the groove 916, the clamping effect of the first plug portion 9142 and the groove 916 is improved, and the connection between the first plug portion 9142 and the inner wall surface of the mounting cavity 9131 is more stable. And when the first plug portion 9142 is inserted into the first connection hole 9133 and the groove 916 for clamping, the first plug portion 9142 can deform relative to the plug body 9141, so that the first plug portion 9142 can smoothly pass through the first connection hole 9133 and then be clamped with the groove 916.
