Description

Technical Field

[0001] This utility model relates to the field of aerosol spraying technology, and more specifically, to an adjustable aerosol spraying nozzle. Background Technology

[0002] Aerosol spraying mainly involves filling the coating and gaseous propellant together in a pressure vessel. The pressure generated by the vaporization of the propellant is then used to spray the coating out of the vessel through a nozzle. Most existing nozzles use a press-to-spray method. However, during the spraying process, it is difficult to adjust the spraying range of the nozzle. The spraying range needs to be adjusted by changing the position of the container, which affects the spraying effect.

[0003] Based on this, an adjustable range aerosol jet nozzle is proposed. Summary of the Invention

[0004] The main objective of this invention is to provide an adjustable aerosol spray nozzle to overcome the problems mentioned in the background section.

[0023] To make the objectives and advantages of this utility model clearer, the utility model will be further described below with reference to the embodiments; it should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0024] Please see Figures 1-4 As shown, an adjustable range aerosol spray nozzle includes a fixed cover 1. A sealing partition 101 is fixedly provided on the upper part of the inner surface of the fixed cover 1. An opening is provided through the middle of the upper surface of the fixed cover 1. A limiting plate 202 is movably mounted on the fixed cover 1 through the inner surface of the opening. A pressing pump head 2 is inserted and fixedly installed on the inner surface of the limiting plate 202. A conduit 201 is fixedly installed on the lower surface of the pressing pump head 2. The other end of the conduit 201 extends outward through the sealing partition 101. A nozzle 203 is fixedly provided on the upper part of the front end of the outer surface of the pressing pump head 2. An adjusting screw 204 is fixedly provided on the front end of the upper surface of the nozzle 203.

[0025] It should be noted that when the fixed cap 1 is installed at the mouth of the aerosol carrier bottle, the sealing effect of the fixed cap 1 and the container bottle can be ensured by setting the sealing partition 101 during the adjustment of the spray range of the press pump head 2. Pressing the press pump head 2 can draw the aerosol in the container bottle through the conduit 201 and spray it out through the nozzle 203 to complete the aerosol spraying.

[0026] A fixing ring 3 is fixedly installed on the lower part of the outer surface of the press pump head 2. A lever 301 is fixedly installed at the middle of the rear end of the outer surface of the fixing ring 3. A limit seat 4 is fixedly installed on the upper surface of the press pump head 2. A support rod 401 is movably inserted into the middle of the upper surface of the limit seat 4.

[0027] It should be noted that the pump head 2 can be pressed by pressing the support rod 401 to achieve the effect of spraying aerosol. At this time, the support rod 401 is used as the pressing point, and under the limiting action of the limiting seat 4, the support rod 401 and the pump head 2 are in a movable connection state. The fixed cover 1 is used as the support point, and under the limiting action of the limiting plate 202, the pump head 2 and the fixed cover 1 are in a movable connection state. At this time, the lever 301 can be moved to control the pump head 2 to rotate, thereby controlling the spray angle adjustment of the nozzle 203.

[0028] A locking ring 5 is spirally inserted into the inner surface of the nozzle 203. A rubber ring 501 is fixedly provided at the front end of the outer surface of the locking ring 5. Support plates 502 are fixedly provided at the center of the four sides of the front end of the outer surface of the rubber ring 501. The support plates 502 are arranged in a fan shape. A rubber sheet 503 is fixedly provided on the outer surface of the support plates 502 that are close to each other. A fixing ear 504 is fixedly provided at the center of the outer surface of the support plates 502. An adjusting rope 6 is inserted into the interior of the fixing ear 504.

[0029] It should be noted that by screwing the locking ring 5 into the nozzle 203, the installation connection between the support plate 502 and the nozzle 203 is completed. Since both the rubber ring 501 and the rubber sheet 503 are thin sheets made of rubber, the fixing ear 504 limits the adjustment rope 6. By adjusting the rope 6, the support plate 502 can be controlled to close and expand. When the adjustment rope 6 is contracted, it can squeeze the support plate 502. At this time, the rubber sheet 503 will deform under pressure and fold and shrink, thereby driving the support plate 502 to close and reduce the spray range of the nozzle 203. When the adjustment rope 6 is expanded, the pressure on the rubber sheet 503 is released. At this time, the rubber sheet 503 begins to rebound and deform, driving the support plate 502 to expand and increase the spray range of the nozzle 203.

[0030] One end of the adjusting rope 6 is fixedly provided with a support ring 601, and the support ring 601 is engaged with one of the fixed ears 504. The other end of the adjusting rope 6 passes through the support ring 601 and extends outward to be fixedly provided with an adjusting nut 602. The adjusting nut 602 is spirally sleeved onto the outer surface of the adjusting screw 204.

[0031] It should be noted that by engaging the support ring 601 with the fixing ear 504, the stability of the adjusting rope 6 inserted within the fixing ear 504 is ensured, preventing it from coming loose. The adjusting nut 602 moves up and down on the adjusting screw 204. When the adjusting nut 602 spirals upward, it controls the adjusting rope 6 to rotate and contract. When the adjusting nut 602 spirals downward, it controls the adjusting rope 6 to rotate and expand. The stable connection between the adjusting nut 602 and the adjusting screw 204 ensures the adjustment stability of the adjusting rope 6.

[0032] When using this invention, the aerosol spray can first be placed into a container bottle and tightly connected to the container bottle using the fixing cap 1. At this time, the support rod 401 can be pressed to control the pressing pump head 2 to press and spray the aerosol in conjunction with the guide tube 201. During the spraying process, the support rod 401 is used as the pressing point, and under the limiting action of the limiting seat 4, the support rod 401 and the pressing pump head 2 are in a movable connection state. The fixing cap 1 is used as the support point, and under the limiting action of the limiting plate 202, the pressing pump head 2 and the fixing cap 1 are in a movable connection state. At this time, the lever 301 can be moved to control the pressing pump head 2 to rotate and control the nozzle 203 to rotate synchronously to adjust the spray angle.

[0033] Secondly, the adjusting nut 602 can be moved up and down on the adjusting screw 204. When the adjusting nut 602 spirals upward, it can drive the adjusting rope 6 to rotate and retract. Since the other end of the adjusting rope 6 is wrapped around the surface of the support plate 502 under the limiting action of the fixing ear 504, when the adjusting rope 6 retracts, it can tighten and squeeze the support plate 502. The film 503 can be deformed by the pressure and folded and retracted, thereby driving the support plate 502 to close and reduce the spray range of the nozzle 203. When the adjusting nut 602 spirals downward, it can drive the adjusting rope 6 to rotate and expand. At this time, the end of the adjusting rope 6 wrapped around the surface of the support plate 502 can be relaxed and extended, and the pressure on the film 503 is released. At this time, the film 503 begins to rebound and deform, driving the support plate 502 to unfold and expand the spray range of the nozzle 203, thus achieving the effect of adjusting the spray range of the nozzle 203.

[0034] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
