[ detailed description ] embodiments

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 1 to 4, a water flow sensor convenient for inserting and positioning of an inductor comprises a sensor body 1, wherein a water cavity 10, a water inlet, a water outlet, an impeller, a hall element and the like are arranged on the sensor body 1, magnetic poles are arranged on the impeller, the impeller rotates when water flows through, and the hall element induces the magnetic change of the magnetic poles on the impeller. The sensor body 1 is provided with the plug platform 2, the plug platform 2 is provided with a plug hole 21 for the plug 5 to be inserted, the plug 5 can be an induction head of a temperature sensor and the like, the plug hole 21 can be communicated with the water cavity 10, and the plug 5 is provided with a sealing ring and the like, so that the plug 5 and the plug hole 21 are sealed. The inserting platform 2 is also provided with a positioning inserting part 3 communicated with the inserting hole 21 and a locking part 4 which is inserted into the positioning inserting part 3 to lock the inserting head 5, and when the inserting head 5 is inserted and fixed through the locking part 4, the inserting head is not easy to fall off, so that the sensor is convenient to monitor.

The positioning insertion part 3 is an insertion groove which is arranged on the side wall of the insertion platform 2 and is communicated with the insertion hole 21, the insertion groove is an annular groove, the annular groove surrounds a circle on the outer side wall of the insertion platform 2, the insertion platform 2 is a square platform in the figure, and the annular groove is arranged on four side walls of the square platform. The locking piece 4 is an elastic clamp transversely clamped on the positioning insertion part 3, which transversely refers to the axial direction perpendicular to the insertion hole 21, the elastic clamp is clamped on the positioning insertion part 3 and tightened by elastic force, so that the locking piece 4 is contracted into the insertion hole to position the insertion joint 5, the elastic clamp comprises two elastic clamping rods 41 oppositely arranged and inserted into the positioning insertion part 3 to lock the insertion joint 5, the two elastic clamping rods 41 are respectively inserted into the annular groove from two opposite surfaces of the insertion platform 2, the elastic clamp is contracted by the elastic force to enable the elastic clamping rods 41 to extend into the insertion joint 5 to position the insertion joint 5, the insertion joint 5 is used as a standard piece, a positioning step 51 is usually arranged on the insertion joint 5, the locking piece 4 is pressed against the end surface of the positioning step 51 after being inserted from the positioning insertion part 3, the locking piece 4 is arranged in the insertion groove to position the locking piece 4 through the insertion groove, the locking member 4 cannot move in the axial direction of the insertion hole 21, and therefore the plug 5 cannot be pulled out of the insertion hole 21, thereby locking the plug 5.
