Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are merely intended to more clearly illustrate the technical solution of the present invention, i.e. to give a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these specific details. In these examples, some technical features that are known in the art have not been described in order to avoid obscuring the present invention.

It is understood that the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, which are intended to be illustrative only and should not be construed as limiting the scope of the invention.

In addition, it should be noted that technical or scientific terms used herein should have the ordinary meaning as understood by those skilled in the art to which the present invention belongs, unless otherwise specified.

Referring to fig. 1 to 3, a spray head for a sprayer is connected with a spray rod 2 below the spray head 1, and a rotary seat 3 is arranged between the spray head 1 and the spray rod 2 and is formed by splicing and fixing a left rotary half shaft 31 and a right rotary half shaft 32; an insert sleeve 33 is arranged at the axle center of the left rotary half shaft 31, a sealing ring 34 is arranged in the insert sleeve 33, an inner shaft sleeve 35 is arranged corresponding to the right rotary half shaft 32 of the insert sleeve 33, and the insert sleeve 33 is sleeved outside the inner shaft sleeve 35 to enable the sleeve edge of the inner shaft sleeve 35 to abut against the sealing ring 34; the outer side of the axle center of the left rotary half shaft 31 passes through the center of the plug bush 33 through a fixing piece 36 and is fixed in the inner shaft sleeve 35, a gasket is further arranged between the fixing piece 36 and the left rotary half shaft 31, and the fixing piece 36 is a screw; a water inlet cavity 38 is arranged between the outer side of the plug bush 33 of the left rotary half shaft 31 and the left shaft shell 37, a water inlet hole 39 is arranged on the left shaft shell 37 and communicated with the spray rod 2, a water outlet cavity 41 is arranged between the outer side of the shaft sleeve 35 in the right rotary half shaft 32 and the right shaft shell 40, and a water outlet hole 42 is arranged on the right shaft shell 40 and communicated with the spray head 1.

The spray head 1 comprises a nozzle core 11, a nozzle cap 12, a nozzle sealing ring 13 arranged between the nozzle core 11 and the nozzle cap 12, and a nozzle adjusting cap 14 used for rotatably adjusting the mist adjusting effect, wherein a right rotating half shaft 32 is actually directly screwed with the bottom of the nozzle core 11.

In this embodiment, the rotary seat 3 can make at least 180 degrees of rotation between the spray head 1 and the spray bar 2 in a vertical plane. Because the split position of the left rotating half shaft 31 and the right rotating half shaft 32 is at the axle center of the left rotating half shaft and the right rotating half shaft, the hinge point is also at the axle center, and the periphery of the axle center is the water inlet cavity 38 and the water outlet cavity 41, so that the spatial arrangement of water inlet and water outlet can be more reasonable, namely the rotating angle of the spray head 1 can be increased, and the water inlet amount and the water outlet amount are not influenced.

Further, it is right as the improvement of the utility model, link to each other through the screw thread between shower nozzle 1 and the right-hand rotation semi-axis 32, be equipped with concave tooth 15 in shower nozzle 1 connection port department, match concave tooth 15 and be equipped with lug 16 at the border of right-hand rotation semi-axis 32 and shower nozzle 1 junction.

After the spray head 1 is rotatably mounted at a screw hole above the right rotary half shaft 32, the concave teeth 15 at the connecting port of the spray head 1 fall onto the convex blocks 16. When the sprayer 1 is sprayed under high pressure, the atomizing plate vibrates, so that the sprayer 1 vibrates, the right rotary half shaft 32 tends to rotate and retreat along the thread direction, and at the moment, the concave teeth 15 touch the convex blocks 16 and cannot slide through the convex blocks 16 due to small vibration under the action of the convex blocks 16, so that the sprayer plays a good role in preventing retreat. It should be noted that the concave teeth 15 can slide over the convex blocks 16 when the human power is intentionally rotated.

Further, as right the utility model discloses an improvement, the plug bush 33 mouth of left-hand rotation semi-axis 31 axle center department is along being equipped with a dog 43, corresponds dog 43 and is equipped with blend stop 44 in the right-hand rotation semi-axis 32 outside axle sleeve 35.

In this embodiment, the blocking strip 44 on the outer side of the sleeve 35 in the right rotating single shaft 32 can prevent the stop 43 from abutting against the blocking strip 44 when the left rotating half shaft 31 rotates along with the spray head 1, and can prevent the right rotating half shaft 32 from further rotating, which limits the range of the rotation of the spray head 1 in the same direction, and when the spray head rotates in the reverse direction, the blocking strip 44 can be limited on the other side, and the blocking strip 44 is arranged here to satisfy the limiting function when the spray head rotates for use.

In addition, during implementation, the barrier strips 44 can be set at certain intervals according to design requirements, so that the angle formed by adding the forward rotation and the reverse rotation can be set according to the rotation angle of the sprayer in use scene control.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
