Description

Technical Field

[0001] The utility model relates to the technical field of humidifiers, in particular to a movable nozzle for a spray humidifier. Background Art

[0002] The nozzle is used in the spray humidifier of the combined air conditioning unit. As one of the core components of the spray humidifier, the clean water is pressurized by the water pump and then sprayed out through the nozzle to form a large amount of water mist particles to humidify, cool and purify the air. As the end of the spray humidifier, the nozzle is usually installed on the spray pipeline. The nozzle is generally a threaded interface. When installing, it is necessary to consider the docking and sealing with the spray pipeline. Usually, the nozzle is installed against the airflow direction or along the airflow direction to ensure that the coverage section is complete and the spray is uniform.

[0003] Most of the spray pipes used to install nozzles are directly welded with internal threads, while the nozzles use external threads that match the internal threads. During installation, raw tape is used to seal and tighten the threaded interface between the spray pipe and the nozzle. However, since it is difficult to control the amount of raw tape used for each nozzle to be exactly the same, the direction of the nozzle installation cannot be controlled while ensuring locking. In order to control the direction of the nozzle, some nozzles cannot be completely locked, which causes water seepage and falling off of the nozzle. In addition, winding the raw tape is labor-intensive and time-consuming, and the exposed raw tape requires additional processing. While increasing labor costs, the appearance is not beautiful enough. In addition, the raw tape cannot be reused, and new raw tape needs to be used again after the nozzle is disassembled and replaced. Therefore, there is an urgent need for a flexible nozzle for a spray humidifier to solve the above problems. Utility Model Content

[0025] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figures 1 to 4As shown, the utility model provides a movable nozzle for a spray humidifier, including a nozzle body, the nozzle body including a nozzle pipe 1, a sleeve nut 2, a movable nozzle 3 and a sealing member, the nozzle pipe 1 is provided with an inlet end, a flow channel and an outlet end which are connected in sequence, the inlet end is welded and connected with a main pipe 5 on the spray humidifier, the main pipe 5 is passed with spray water, and the spray water flows out through the inlet end, the flow channel and the outlet end, the outer wall of the nozzle pipe 1 is provided with a limiting boss 11 and the limiting boss 11 is located at the nozzle pipe At the outlet end of the nozzle pipe 1, the sleeve nut 2 is provided with a through cavity, the inlet end of the nozzle pipe 1 passes through the through cavity, the outlet end of the nozzle pipe 1 is located in the through cavity and the limiting boss 11 abuts against the inner wall of the through cavity, the sleeve nut 2 is sleeved (slipped) on the outer wall of the nozzle pipe 1 through the limiting boss 11, the inner wall of the through cavity is provided with an internal thread 21, the slip-joint nozzle 3 is provided with an external thread 31 matching the internal thread 21, and the sleeve nut 2 is sealed and connected with the slip-joint nozzle 3 through a sealing member. The sealing member is installed in the through cavity, and the sleeve nut 2 and the slip-joint nozzle 3 are thread-sealed and connected through the internal thread 21 and the external thread 31. At this time, the sleeve nut 2 remains fixed on the outer wall of the nozzle pipe 1, and the spray water can be sprayed through the sleeve nut 2 to the slip-joint nozzle 3, and the spray water does not leak from the connection between the sleeve nut 2 and the slip-joint nozzle 3.

[0027] The spray humidifier of this embodiment uses a flexible nozzle. The sleeve nut 2 is first slidably mounted on the outer wall of the nozzle pipe 1 through the limiting boss 11, and the sealing member is installed in the through cavity. The sleeve nut 2 is then threadedly sealed with the flexible nozzle 3 through the internal thread 21 and the external thread 31. After the sleeve nut 2 is threadedly sealed with the flexible nozzle 3, the sleeve nut 2 remains fixed on the nozzle pipe 1. When it is necessary to adjust the position or water outlet direction of the flexible nozzle 3, the flexible nozzle 3 is separated from the sleeve nut 2. Since the sleeve nut 2 is slidable, it is only necessary to rotate the sleeve nut 2, and then the sleeve nut 2 is sealedly connected to the flexible nozzle 3. The sleeve nut 2 can be rotated at any angle along the circumference of the nozzle pipe 1, thereby realizing the free adjustment direction of the flexible nozzle 3 by 360°.

[0028] Compared with the existing nozzle installation method, the movable nozzle for the spray humidifier of this embodiment can adjust the movable nozzle 3 according to the required angle, and the movable nozzle can freely adjust the direction by 360°, which is simple, convenient and flexible.

The gasket 4 can make the union nozzle 3 and the sleeve nut 2 threaded and sealed. The gasket 4 can be reused, which simplifies the installation procedure and does not require manual winding of the raw tape. Among them, the gasket 4 is a polytetrafluoroethylene gasket.

[0030] As an implementation method, an inner convex ring 22 is provided on one side of the through cavity, the outer diameter of the nozzle pipe 1 is smaller than the inner diameter of the through cavity and the inner diameter of the inner convex ring 22, the outer diameter of the limiting boss 11 is smaller than the inner diameter of the through cavity and larger than the inner diameter of the inner convex ring 22, the inlet end of the nozzle pipe 1 passes through the through cavity and the inner convex ring 22 in sequence, the outlet end of the nozzle pipe 1 is located in the through cavity and the limiting boss 11 abuts against the inner convex ring 22.

The shape and structure of the main pipe 5 are designed according to the specific requirements of the spray humidifier. The main pipe 5 is provided to enable the nozzle body to spray.

[0032] As an implementation method, the nozzle body is provided with a plurality of nozzle bodies, and the plurality of nozzle bodies are connected and communicated with the main pipe 5 through the inlet end of the nozzle pipe 1, and the plurality of nozzle bodies are evenly arranged on both sides of the main pipe 5. The number of nozzle bodies can be designed according to the specific needs of the spray humidifier. The articulated nozzle can freely adjust the direction by 360°, which can ensure the uniformity and aesthetics of the direction adjustment of the plurality of articulated nozzles.

[0033] Although the gasket 4 can seal the union nozzle 3 and the sleeve nut 2, it is still difficult to completely lock the two due to the elasticity of the gasket 4. The union nozzle 3 and the sleeve nut 2 may become loose under the condition of vibration during operation.

[0034] Therefore, if Figures 5-6 As shown, the utility model also provides another movable nozzle for a spray humidifier. The structure of the movable nozzle in this embodiment is the same as that of the above-mentioned movable nozzle. The nozzle body also includes a lock nut 6, and the lock nut 6 is arranged between the sleeve nut 2 and the movable nozzle 3. The lock nut 6 is located outside the through cavity.

[0035] In the present embodiment, the spray humidifier uses a flexible nozzle, the sleeve nut 2 is firstly sleeved on the outer wall of the nozzle pipe 1 through the limiting boss 11, the gasket 4 is installed in the through cavity, and then the lock nut 6 is screwed on the external thread 31 of the nozzle, and the sleeve nut 2 is finally threaded and sealed with the flexible nozzle 3 through the internal thread 21 and the external thread 31. After the lock nut 6 is arranged, the lock nut 6 abuts between the flexible nozzle 3 and the sleeve nut 2, and the sleeve nut 2 and the lock nut 6 are locked to prevent loosening, so as to prevent the flexible nozzle 3 and the sleeve nut 2 from loosening under the condition of vibration during operation, and even the situation that the flexible nozzle 3 falls off or falls off.
