Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

Example one, see fig. 1-3;

the nozzle of the utility model is mainly used together with the tooth rinsing device body, but the nozzle structure of the utility model can be applied to different products with spraying function, so the main using mode is not taken as the limit of the protection range, and the embodiment takes the application of the nozzle in the tooth rinsing device body as an example for explanation; the using mode of the nozzle of the utility model is the same as that of the existing nozzle, one end of the nozzle is connected with the tooth flusher body, and the other end is a water outlet for spraying flushing liquid; when the water-gas mixing spray nozzle is used, flushing liquid is pressurized by the tooth punching device body and then enters the first water channel in the nozzle body 1, then is sprayed out from the water outlet 134 of the first water channel and enters the water-gas mixing space 12 in the nozzle end 11, because the flow speed of the flushing liquid is very high when the flushing liquid is sprayed out from the first water channel, the pressure in the water-gas mixing space 12 is smaller than the pressure in the space outside the nozzle body 1 by utilizing the Bernoulli principle, at the moment, air in the outer space enters the water-gas mixing space 12 through the first air hole 14 to be mixed with the flushing liquid so as to generate bubbles to be sprayed out from the water outlet 111 of the nozzle end 11, and because the caliber of the water-gas mixing space 12 is larger than the caliber 134 of the first water channel 13, the concrete shape can be frustum, cylinder and the like, the flushing liquid can be sprayed out, so that a part of the flushing liquid can collide with the inner wall of the water-gas mixing space 12 to be rolled and then is mixed with the outer air, can produce more bubbles, under the same injection quantity, adopt the nozzle can produce more bubbles to promote clean effect.

In this embodiment, the number of the first air holes 14 is two, and in a preferred embodiment, the two first air holes 14 are symmetrically arranged.

The present embodiment further describes the nozzle body 1;

the nozzle body 1 further comprises a neck portion 16 connected with the nozzle end 11, an installation portion 17 is arranged at one end, far away from the nozzle end 11, of the neck portion 16, the installation portion 17 is connected with the tooth flushing device body, a second water channel 18 is arranged in the installation portion 17, the second water channel 18 is communicated with a first water channel located at the neck portion 16, and the caliber of the second water channel 18 is the same as that of the joint of the first water channel 13.

Embodiment two, refer to fig. 2 and 4;

in this embodiment, the first water channel 13 is conical, that is, the aperture is smaller at the position closer to the water outlet 134 of the first water channel 13, so as to further increase the flow rate of the flushing liquid;

the first water channel 13 is further refined on the basis of the conical shape and comprises a first flow channel 131 and a second flow channel 132 with different inclination angles, when the flushing liquid passes through the second flow channel 132, the flow speed of the flushing liquid is firstly improved, and after the flushing liquid flows into the first flow channel 131 from the second flow channel 132, the inclination angle of the inner wall of the first flow channel 131 is larger than that of the inner wall of the second flow channel 132, so that the flow speed of the flushing liquid can be secondly improved; in this embodiment, a third flow channel 133 is further disposed between the first flow channel 131 and the water-gas mixing space 12, and the aperture of the third flow channel 133 is the same as the aperture of the joint of the first flow channel 131, and mainly plays a role in guiding.

Preferably, referring to fig. 4, the nozzle body 1 is provided with a hollow nozzle 15 in the water-air mixing space 12, the nozzle 15 is communicated with the first water channel 13, the accelerated flushing liquid is further guided, and further, the end surface of the water outlet of the nozzle 15 is higher than the first air hole 14, so that the air intake effect is better.

Example three, refer to fig. 5 and 6;

because the bore of the water outlet 111 of the sprinkler head 11 is relatively small, the spraying range of the washing liquid is limited, in this embodiment, the end part located at the sprinkler head 11 is provided with at least one groove 112 along the circumferential direction, when the washing liquid is sprayed out from the water outlet 111 of the sprinkler head 11, the grooves 112 have a guiding function, part of the washing liquid can be sprayed out from the direction along the grooves 112, the spraying angle is larger, when the number of the grooves 112 is two, the grooves are symmetrically arranged, the spraying amount of the washing liquid in the two grooves 112 is uniform, preferably, the number of the grooves 112 is four, the distance between the adjacent grooves 112 is 90 degrees, in addition, the arrangement of the grooves 112 can effectively avoid that the washing liquid is sprayed out from the first air hole 14 when the water outlet 111 is blocked, and air is blocked from the first air hole 14.

The utility model also provides a tooth ware towards including the mixed washing nozzle of aqueous vapor, because with the utility model discloses the mixed washing nozzle of aqueous vapor embodiment is based on same design, its technical effect who brings with the embodiment of the utility model provides a same, concrete content can see the utility model discloses narration in the mixed washing nozzle of aqueous vapor embodiment, no longer repeated here.
