A nozzle C provided with a second jet outlet 57 is rotatably fitted to the main body A via the element B, and a first flow path extending from the main body A to only the first jet outlet 53, and the main body A trigger type liquid ejector configured such that the second flow path extending from the inside of A to only the second ejection port 57 can be switched by the rotation of the nozzle C, and the element B has a central axis 27 at the center of the front surface, A cylindrical portion 28 that projects inwardly from the inside of the main body A is protruded, and a rotating cylinder 40 that protrudes from the back surface of the nozzle C is rotatably fitted to the outer surface of the cylindrical portion 28 and protrudes from the center of the nozzle back surface. Between the central shaft 27 and the cylindrical portion 28. The first flow path is fitted into the first communication groove 30 drilled at the outer peripheral tip of the central shaft 27 and the third continuous channel drilled at the rear end of the inner periphery of the connecting cylinder portion 43. In a state where the communication groove 45 is communicated, the first communication groove 30 communicates with the first ejection port 53 through the first through hole 63 penetrating the nozzle front wall 41, and the second flow path is formed on the cylindrical portion 28. The second communication groove 33 is connected to the nozzle front wall 41 in a state where the second communication groove 33 formed in the inner periphery communicates with the fourth communication groove 46 formed in the rear end of the outer periphery of the connection cylinder portion 43. The second jet port 57 communicates with the second jet port 57 through a second through hole 64 penetrating through the nozzle.

  The second means is configured as follows. That is, in the first means, the cylindrical portion 28 is extended through the flange 28b to the sliding cylindrical portion 28a that is liquid-tightly rotated around the outer periphery of the rear half of the connecting cylindrical portion 43, and the distal end of the sliding cylindrical portion 28a. A seal cylinder portion 44 that is configured by the large-diameter cylinder portion 28c provided and protruded from the back surface of the nozzle C on the inner periphery of the large-diameter cylinder portion 28c is fitted in a liquid-tight manner.

  The third means was configured as follows. That is, in the first means, the cylindrical portion 28 is fitted to the entire outer periphery of the connecting cylindrical portion 43 so as to be able to rotate in a liquid-tight manner, and the flange 28b from the outer surface of the sliding cylindrical portion 28a.

  According to the present invention, when the first flow path is in communication, it is possible to spray a mist with a large particle size, and it is possible to spray a mist with a fine particle size by switching to the second flow channel. Since these switching operations can be performed by a simple operation of rotating the nozzle C, the handling is extremely convenient. Moreover, since the 1st flow path is formed in the inner position of the connection cylinder part 43, and the 2nd flow path is formed in the outer position of the connection cylinder part 43, the center axis | shaft 27 and nozzle which are poor in sealing performance, for example Even if the liquid may enter between the front wall 41, there is no further place for the liquid to flow, and as a result, there is no inconvenience that the liquid leaks to a portion other than the first flow path. .

The sealing cylinder portion 44 is provided on the inner periphery of the fitting cylinder portion 28c so as to protrude from the back surface of the nozzle C. Similarly, when the rotation is fitted, the liquid tightness of this portion in the second flow path can be more surely exhibited, and the sliding cylinder portion 28a is immediately after the back surface of the nozzle C. Therefore, the second flow path between the sliding cylinder portion 28a and the back surface of the nozzle C can be formed without making a wasteful wide space. There is an advantage that inconveniences such as air stagnation in the flow path can be prevented more reliably.

  When the cylindrical portion 28 is fitted to the entire outer periphery of the connecting cylindrical portion 43 in a liquid-tight and rotatable manner, the cylindrical portion 28 extends to the position immediately after the back surface of the nozzle C. It is possible to form the second flow path between the nozzle 28 and the back surface of the nozzle without making a useless wide space. For example, the initial flow may cause inconvenience such as air stagnation in the second flow path. There is an advantage that can be prevented more reliably.

  In addition to the communication position of the first flow path with respect to the main body A of the nozzle C and the communication position of the second flow path, the stop position where the inside of the main body A and each of the first jet ports 53 and the second jet ports 57 are not in communication.

There is an advantage that a stable fog state can be always displayed.
