The lower extreme of barrel 40 is provided with water diversion disc 50, a plurality of inlet openings 51 that are the annular and distribute are seted up to the periphery of water diversion disc 50, and its top middle part is fixed and is set up spacing awl 60. The movable sleeve is equipped with level pressure flotation pontoon 70 on the guide cone 60, just the lower terminal surface of level pressure flotation pontoon 70 covers completely and establishes on the inlet opening 51, level pressure flotation pontoon 70 the hole with form out the water passageway between the guide cone 60.

In some embodiments, as shown in fig. 4 and 5, in order to facilitate the installation and the detachment of the connector 30, a first engaging groove 31 is formed in an inner side wall of an upper end of the connector 30, a first snap ring 41 is disposed on an outer peripheral wall of a lower end of the cylinder 40, the first engaging groove 31 and the first snap ring 41 can be locked and fixed by a conventional male snap and female snap structure, and the connector 30 can be connected to the cylinder 40 by a thread manner as required.

In some embodiments, as shown in fig. 3, 5 and 6, an annular limiting groove 42 is formed in an inner side wall of the lower end of the cylinder 40, and an outer periphery of the water diversion disc 50 is sealingly embedded in the limiting groove 42. Specifically, the water diversion disc 50 is mounted in the limiting groove 42 through a sealing ring, so that water below the water diversion disc 50 is prevented from entering the upper part through the limiting groove 42, and a pressurization effect is achieved.

In some embodiments, as shown in fig. 3, 5 and 6, the guide cone 60 may be welded or detachably fixed to the middle of the water diversion disc 50. Preferably, a through hole 52 is formed in the middle of the water diversion disc 50, and the lower end of the guide cone 60 passes through the through hole 52 and is fastened with a connecting nut 61.

In some embodiments, as shown in fig. 2, 3, 8 and 9, the amount of water pressure sprayed by the spinner 80 can be controlled by adjusting the weight of the constant pressure float 70, and the larger the weight of the constant pressure float 70 is, the larger the water pressure required to lift the constant pressure float 70 from the bottom of the constant pressure float 70 is, which in turn results in the larger the flow rate through the spray holes 81 of the spinner 80, and at the same time, the larger the reverse force applied to the spinner 80, the faster the spinner speed. In order to facilitate the control of the jet flow rate and the rotation speed of the rotary nozzle 80, an annular groove 72 is formed in the outer peripheral wall of the upper end of the constant pressure float 70, and ceramic counterweight rings 71 with different weights can be sleeved in the annular groove 72 as required.

As a preferred embodiment, as shown in fig. 3 and 9, the inner hole 73 of the constant pressure float 70 is in a frustum-shaped structure with a gradually decreasing diameter, and is matched with the guide cone 60 arranged therein, so that a water outlet channel is formed between the inner hole of the constant pressure float 70 and the guide cone 60. As can be seen from the figure, the lower end of the water outlet channel is narrower, and the water outlet 51 is easier to block under the action of the self weight of the constant pressure buoy 70.

In some embodiments, as shown in fig. 1, 2, 3 and 10, the upper end of the rotary sprayer 80 is a hollow conical structure, a plurality of tangentially arranged spray holes 81 are opened on a cone, and the outlet directions of the spray holes 81 are obliquely arranged upwards to form a beautiful water posture of upward spraying.

In addition, it should be noted that, in order to ensure that the rotary spray head 80 can rotate under the reverse action of the water jet, it is required to reduce the friction at the joint of the rotary spray head 80 and the cylinder 40 as much as possible, and preferably, a lubricating coating is sprayed on the surface of the joint of the rotary spray head 80 and the cylinder 40 to reduce the resistance of the rotary spray head 80 during rotation.

In order to improve the jet velocity of the rotary nozzle 80 and reduce the kinetic energy loss of high-pressure water flow, at least a diversion column 83 is arranged at the top end inside the rotary nozzle 80, the lower end of the diversion column 83 is in an inverted cone shape, and high-pressure water flowing out through a water outlet channel is dispersed outwards through the diversion column 83 to play a certain role in buffering and diversion.

In addition, as shown in fig. 1, 2 and 3, the rotary constant pressure nozzle for an outdoor landscape fountain further comprises an outer sheath 90, and the outer sheath 90 is sleeved on the barrel 40. The outer sheath 90 can be made of heat-insulating cotton and the like, and is used for performing certain heat insulation and protection effects on the cylinder body 40 and preventing water in the cylinder body 40 from freezing under the low-temperature condition in winter.

With continued reference to fig. 1, 2 and 3, the rotary constant pressure nozzle for an outdoor landscape fountain operates as follows: the water flow passing through the main water pipe 10 and the water diversion pipe 20 enters the connector 30, when the water flow pressure is small, because the constant pressure float 70 has a certain weight, the constant pressure float 70 seals the water inlet on the water diversion disc under the action of the gravity of the constant pressure float 70, and a water outlet channel formed between the inner hole of the constant pressure float 70 and the guide cone 60 is in a closed state. When the water pressure is gradually increased and the pressure applied to the bottom of the constant pressure float 70 through the water inlet is greater than the gravity of the constant pressure float 70, the constant pressure float 70 is jacked up, a water outlet channel is formed between the inner hole of the constant pressure float 70 and the guide cone 60 and is in an open state, pressurized high-pressure water enters the rotary spray head 80 through the water outlet channel and is sprayed to the periphery from the spray holes 81 which are arranged in a tangent mode on the rotary spray head 80, and the rotary spray head 80 rotates under the action of the spraying reaction force, so that the rotary spray water posture is formed.

The rotary constant-pressure spray head for the outdoor landscape fountain controls the opening or the closing of the water outlet channel by utilizing the dead weight gravity and the water flow pressure of the constant-pressure float bowl through the fixed guide cone and the movable constant-pressure float bowl which are arranged in the barrel body. And the rotary spray head rotates under the reverse acting force of the spraying, thereby realizing the purpose of spraying and rotating simultaneously. In addition, this rotation type level pressure shower nozzle structural design is novel, compact, and the installation is simple, convenient, and is small, need not the external driving motor and can realize rotating, is applicable to general outdoor fountain and uses.
