Used as a kind of preferred version, the installation cavity connects spout chamber by first flow, the first flow include according to The conical section of secondary connection, the first cylindrical section and the second cylindrical section, the internal diameter of conical section is gradually reduced along liquid conveying direction, and first The internal diameter of cylindrical section is equal to the minimum diameter of conical section, and the internal diameter of second cylindrical section is more than the maximum inner diameter of conical section, while Less than the internal diameter in spout chamber.
As a kind of preferred version, second flow channel is provided with the briquetting, the second flow channel includes what is be sequentially connected First conical section, cylindrical section and the second conical section, first conical section is gradually reduced along liquid conveying direction, the cylindrical section it is interior Footpath is equal to the minimum diameter of the first conical section, and second conical section gradually increases along liquid conveying direction, and the second conical section Maximum inner diameter is less than the maximum inner diameter of the first conical section, while again smaller than the internal diameter of mounting seat.
The utility model has compared with prior art clear advantage and beneficial effect, specifically, by above-mentioned technology Scheme understands:
The internal diameter in spout chamber is less than by the external diameter design by installation cavity, compared with conventional waterfog head, due to spout The increase in chamber contact liquid-to-air it is more abundant, atomizing effect becomes apparent from;Also, rotor by briquetting install and and body With reference to, make assembling more quick and easy, cost is also lower.
More clearly to illustrate architectural feature of the present utility model and effect, come right with specific embodiment below in conjunction with the accompanying drawings The utility model is described in detail:

Specific embodiment
Refer to shown in Fig. 1, that show the concrete structure of the preferred embodiment of the utility model, include body 10th, rotor 20 and briquetting 30.
The body 10 is included and have in the spray nozzle part 11 and installation portion 12 for being integrally formed connection, spray nozzle part 11 a spout chamber 101, the open at one end of spray nozzle part 11 simultaneously connects spout chamber 101, and the other end of spray nozzle part 11 is sealing surface, and installation portion 12 is in the envelope Close on face and integrally extend, and air inlet 102 is provided with the sealing surface, the connection spout of air inlet 102 chamber 101 is simultaneously located at installation Installation cavity 103 is provided with the periphery in portion 12, installation portion 12, the external diameter of installation cavity 103 is less than the internal diameter in spout chamber 101.At this In embodiment, the air inlet 102 is multiple, and multiple air inlets 102 are evenly distributed on the periphery of installation portion 12, to realize Even air inlet.Also, the installation cavity 103 connects spout chamber 101 by first flow 104, and the first flow 104 is included successively The conical section 1041 of connection, the first cylindrical section 1042 and the second cylindrical section 1043, the internal diameter of conical section 1041 is along liquid conveying side To being gradually reduced, the internal diameter of the first cylindrical section 1042 is equal to the minimum diameter of conical section 1041, second cylindrical section 1043 it is interior Footpath is more than the maximum inner diameter of conical section 1041, while less than the internal diameter in spout chamber 101.
