Rotary type multi-nozzle proportional spray head

Abstract

The invention discloses a rotary type multi-nozzle proportional spray head. The rotary type multi-nozzle proportional spray head comprises a water inlet pipe, wherein the rear end of the water inlet pipe is connected with a motor; the motor is in transmission connection with a rotary end cover arranged at the front end port of the water inlet pipe through a transmission shaft arranged in the water inlet pipe; the rotary end cover is provided with a radial extending part; the radial extending part is in transmission connection with a sliding support sleeve arranged on the periphery of the front end part of the water inlet pipe in a sleeving manner through a connecting piece; a plurality of water outlet holes are formed in the pipe wall of the sliding support sleeve; the water outlet holes are connected to nozzles through corresponding guide pipes; a water outlet is formed in the pipe wall of the front end part of the water inlet pipe; the water outlet is communicated with the water outlet hole rotating to the position of the water outlet; a stop step raised along the radial direction is arranged on the port of the water inlet pipe between the radial extending part of the rotary end cover and the sliding support sleeve; and a water inlet is formed in the water inlet pipe between the sliding support sleeve and the motor. According to the rotary type multi-nozzle proportional spray head disclosed by the invention, the external volume can be decreased, the matching precision and processing cost are reduced, and the transmission is smooth and reliable.

Description

technical field [0001] The invention relates to a nozzle of a musical fountain, in particular to a rotary multi-nozzle proportional nozzle. Background technique [0002] With the development of the city, the musical fountain has become an indispensable landscape. In the entire music fountain system, the nozzle carries the final modeling function. In order to add to the shape of the music fountain, people have designed a variety of nozzles, including DC nozzles, high nozzle nozzles, trumpet nozzles, Mizuki nozzles, fan nozzles, hibiscus flower nozzles, etc. (such as the utility model with the patent number 201020695796. 201420643732.8 utility model). Yet all these shower heads all have following defect: the nozzle of shower head is either fan-shaped nozzle, or is straight tube nozzle, or is hibiscus flower nozzle etc., can only be one of them, can not change nozzle in water spraying process, and this just The effect of changing the water shape of the musical fountain is gr...

Problems solved by technology

Yet all these shower heads all have following defect: the nozzle of shower head is either fan-shaped nozzle, or is straight tube nozzle, or is hibiscus flower nozzle etc., can only be one of them, can not change nozzle in water spraying process, and this just Greatly reduced the effect of changing the water shape of the musical fountain

However, the disadvantage is that the driving device 7 disclosed in this technical solution is arranged outside the rotating sleeve 3 (see its claim 4 and the appended figure 1 ), which requires lengthening the axial length of the rotating sleeve 3, the longer the axial length of the rotating sleeve 3, the higher the precision requirement for the cooperation between the rotating sleeve 3 and the end 1 of the water inlet pipe, and the greater the processing cost; On the one hand, with this kind of transmission structure, the end 1 of the water inlet pipe will shake, and the meshing between the gear 6 and the driving device 7 will be unstable, and even disengagement may occur.
