Description

Magnetic rotary damping spray head

Technical Field

The utility model relates to a high pressure and ultrahigh pressure water jet field, more specifically the utility model relates to a high pressure nozzle.

Background

High-pressure water jet means a fine "water jet" that is converted into high speed water by a high-pressure water generator after pressurizing water and by a jet device having a milled bore. Such "water jets" have a great percussion energy and can perform different kinds of cleaning tasks. The high-pressure water jet is used for cleaning, and has the advantages of high efficiency, low cost, no damage to workpieces, no environmental pollution, convenient and safe operation and the like; the product is widely used in various industries and is popular in the market.

The high-pressure water jet nozzle can rotate under the action of the recoil force of the water jet, and the multi-directional cleaning is also facilitated. The speed of rotation depends on the injection angle and the water pressure. When the water pressure rises, the rotating speed is too fast, the jet flow is easy to atomize, and a large squeaking sound is generated.

SUMMERY OF THE UTILITY MODEL

To the not enough that exists among the prior art, the utility model aims to provide a rotatory damping shower nozzle of magnetism has solved among the prior art along with water pressure risees, and the rotational speed risees too fast problem.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a magnetic rotary damping spray head comprises a spray head shell, a rotary core shaft, a rotary shaft and a rotary nozzle, wherein one end of the spray head shell is provided with a water inlet connector; a channel for high-pressure jet flow to pass through is arranged between the rotating mandrel and the rotating shaft; the rotating shaft is externally provided with a magnetic speed reduction blade, and the inner wall of the spray head shell is provided with a speed reduction copper sleeve at a position opposite to the speed reduction blade.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model utilizes the principle that the larger the relative rotating speed of the magnetic decelerating blade and the copper sleeve is, the larger the magnetic damping resistance is, and when the water pressure is lower, the rotating speed of the rotating shaft is lower, and the smaller resistance is given to the rotating shaft; when the water pressure rises, the rotating shaft rotates at a higher speed, and a larger resistance is given to the rotating shaft. The rotating speed of the rotating shaft is reduced along with the increase degree of the water pressure, namely, the rotating speed is increased by a small amount under the condition of increasing the same water pressure. So as to reduce the rotating speed of the rotating shaft under high pressure and prevent the generation of atomization effect.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

fig. 3 is an outline view of the present invention.

The water inlet joint comprises a water inlet joint 1, a sealing bush 2, a taper bush 3, a through hole 4, a rotating mandrel 5, a bearing 6, a speed reduction copper sleeve 7, a speed reduction blade 8, a channel 9, a rotating shaft 10, a spray head shell 11, a spray nozzle protective sleeve 12 and a rotating spray nozzle 13.

Detailed Description

In order to make the utility model realize that the technical means, the creation characteristics, the achievement purpose and the effect are clearer and are easy to understand, the following combination and the detailed implementation are right the utility model discloses do further explanation:

as shown in fig. 1-3, a magnetic rotary damping nozzle comprises a nozzle housing 11 having a water inlet connector 1 at one end, a rotary core shaft 5, a rotary shaft 10 sleeved outside the rotary core shaft 5 and rotatably connected to the nozzle housing 11, and a rotary nozzle 13 fixed at a water outlet end of the rotary shaft 10; a channel 9 for high-pressure jet flow to pass through is arranged between the rotating mandrel 5 and the rotating shaft 10; a magnetic speed reduction blade 8 is arranged outside the rotating shaft 10, and a speed reduction copper sleeve 7 is arranged at the position, opposite to the speed reduction blade 8, of the inner wall of the sprayer shell 11.

According to the above technical scheme, the utility model discloses a technical thought does: the rotation of the rotating shaft 10 is used for cutting magnetic induction line motion, reaction force is generated to restrain the rotation of the rotating shaft 10, the larger the rotating speed is, the larger the generated reaction force is, although the increase of the rotating speed cannot be eliminated, the increasing proportion of the rotating speed along with the increase of water pressure can be reduced, and the problem that the water jet gasification generates squeaking sound due to the fact that the rotating speed is too large is solved.

Further, rotatory dabber 5 with be equipped with sealing bush 2 between the water supply connector 1, be equipped with the intercommunication between sealing bush 2 passageway 9 and the inside through-hole 4 of water supply connector 1. Utilize seal bush 2 to seal 5 tip of rotatory dabber, replace rotatory dabber 5 to bear the axial force, utilize the convenience of self shape design to reach the effect of convenient commentaries on classics joining in marriage.

Further, rotatory dabber 5 with sealed bush 2 complex tip sets up in tapering bush 3, the inboard inner wall cooperation of water supply connector 1 along the direction of intaking on tapering bush 3 outer wall and the shower nozzle casing 11, the outer wall of tapering bush 3 reduces along the direction of intaking gradually, rotation axis 10 one end and the contact of 3 tip of tapering bush. In actual operation, due to material considerations and the like, the end of the rotating shaft 10 is not likely to be in direct contact with the head housing 11, and therefore a tapered bushing is provided in contact with the end of the rotating shaft 10 within the head housing 11. And the conical bushing is subjected to larger pressure in the water inlet direction of high-pressure water, and if the conical bushing is arranged to be matched in a cylindrical manner, a complex fixing mode is required, so that the conical bushing is not beneficial to installation. The taper is arranged, and by utilizing the matching of the taper bush and the spray head shell 11, only a fixing structure is arranged at one end facing the water inlet connector 1, and the sliding towards the water inlet direction due to the pressure is not needed to be worried about.
