Specific implementation mode
It is new to this practicality below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type is described in further detail.Only this state, the utility model occur in the text or will occur upper and lower, left and right, it is preceding,
Afterwards, the orientation such as inside and outside word is not the specific restriction to the utility model only on the basis of the attached drawing of the utility model.
Referring to attached drawing 1 to attached drawing 3, the utility model discloses a kind of flowmeters, including bottom case 1 and lid to close bottom case 1
Upper cover 2, forms measurement chamber 3 between the bottom case 1 and upper cover 2, the side wall of the measurement chamber 3 is equipped with the water inlet communicated therewith
Mouth 31 and water outlet 32.
Wherein, the water inlet 31 and water outlet 32 are preferably disposed on bottom case 1, and the bottom case 1, which is located at water inlet 31, to be set
Have into water interconnecting piece 11, the water inlet interconnecting piece 11 is equipped with along the inlet opening of water (flow) direction reduced diameter 12.This practicality is new
Type sets the hole of water inlet to gradually smaller form, i.e. inlet opening 12 is in truncated cone-shaped, with the propulsion of flow, pressure of washing by water
Can be increasing, to ensure the more smoothly rotation of rotor.
In order to realize that the purpose of this utility model, the flowmeter of the utility model further include being rotatably mounted to measurement chamber
The Hall subassembly 5 of rotor 4 and calculating 4 revolution of rotor in 3.By Hall subassembly 5 calculate rotor 4 rotating speed to obtain into
The water flow entered.The rotor 4 is preferably made of nylon, has water sorption by the rotor 4 of nylon support, bubble is in water for a long time
The inside can absorb water, and the size of the rotor 4 after water suction can become larger, and so as to prevent following magnet from falling off, but not influence to turn
Son 4 works normally, and the rotor 4 of the prior art generally uses POM materials, and does not have this function.
Wherein, the rotor 4 include central shaft 41 and along central shaft 41 circumferential direction be intervally arranged successively it is multiple
