Description

Technical Field

[0001] This utility model generally relates to a spray nozzle. Background Technology

[0002] Spray nozzles and devices have been in use for a long time. Nozzles are typically screwed or attached to hoses to produce a variety of sprays for cleaning. Most spray nozzles are made of metal, which can cause scratches if there is accidental contact when used near the object being cleaned. Therefore, there is a need for a spray nozzle that does not produce the same drawbacks seen in past or current designs. Utility Model Content

[0003] This invention aims to provide a unit-type, single-mold spray nozzle. The nozzle includes a body extending from an inlet end to an outlet end. The body has a hollow cavity from the inlet end to the outlet end to create a continuous internal section. The inlet end includes an internal thread for attachment to a liquid source. An inlet ring is positioned above the internal thread within the hollow cavity and extends toward the centerline of the internal section, such that the inlet ring is configured as a stop when a hose is screwed into the inlet end. The outlet end includes a pair of slotted nozzles with an outlet point in fluid communication with the hollow cavity. The slotted nozzles are configured to produce a liquid spray or liquid wall upon spraying. The slotted nozzles are configured with a narrowed nozzle outlet to increase the liquid pressure upon spraying. A handle is fixed to the outside of the body. The handle has a pair of diametrically opposed rods that extend into the body and are fixed to a ball valve positioned within the internal section of the body. The ball valve is positioned within the internal section such that it divides the internal section into an inlet section and an outlet section. The ball valve has a passage opening that aligns with the internal section when the handle is in the open position, allowing liquid to flow from the inlet end through the internal section to the outlet end. When the handle is moved to the closed position, the passage opening moves to seal the internal section, preventing liquid from flowing from the inlet end to the outlet end. The handle is configured to move to the intermediate position, such that the ball valve's passage opening is neither fully aligned nor fully closed, thereby reducing liquid flow from the inlet end to the outlet end.

[0004] In another aspect of the embodiment, the body, handle, and ball valve are integrally molded from a semi-rigid material selected from the group consisting of plastics, polypropylene, and thermoplastic rubber. Attached Figure Description

[0017] While this invention is susceptible to many different embodiments, preferred embodiments of the invention are shown in the accompanying drawings and will be described in detail herein. However, it should be understood that this disclosure is to be considered as an example of the principles of the invention and is not intended to limit the spirit or scope of the invention and the illustrated embodiments.

[0018] Please refer to the accompanying drawings for more details, and first refer to... Figures 1 to 10 This utility model is embodied in a unit-type single-mold spray nozzle 100. The spray nozzle 100 has a body 110 extending from an inlet end 120 to an outlet end 130. The body 110 is hollow, forming an internal section 115.

[0019] Inlet end 120 is secured to a liquid source, such as a hose or a powered sprayer. Inlet end 120 includes an internal thread 125 that closely abuts the end of the hose. Additionally, inlet end 110 includes an inlet ring 127 positioned above the internal thread 120 and extending toward the centerline of an inner section 115 defined within body 110. When the hose is screwed into inlet end 120, the inlet ring acts as a stop for the hose.

[0020] The outlet end 130 includes a pair of slotted nozzles 135 having an outlet point for spraying liquid or water and fluidly communicating with an internal section 115 of the body 110. The slotted nozzles 135 are configured with narrowed slots 145 to increase the pressure of the liquid as it is sprayed from the spray nozzle 100.

[0021] Additionally, the spray nozzle 100 may include a handle 150 fixed to the exterior of the body 110. The handle 150 includes a pair of diametrically opposed rods 155 extending from the handle 150 through the body 110 and fixed to a ball valve 160 positioned within an inner section 115 of the body 110. The ball valve 160 has a passage opening 170 that aligns with the inner section 115 when the handle is in an open configuration 180, allowing liquid to pass through the inner section to the outlet end 130. When the handle 150 is moved to a closed configuration 190, the passage opening 170 moves, causing the ball valve to close to the inner section 115, preventing liquid from moving to the outlet end 130.

[0022] Figure 8 Specifically, the handle 150 is shown in the middle position, such that the ball valve 150 and its passage opening 170 are neither fully aligned nor fully closed.

[0023] As shown in the figure, the internal section 115 can be divided into multiple sections: a first section 200, which is configured between the inlet end and the ball valve; a second section 210, which is configured between the ball valve and the outlet end; and a third section 220, which extends from the outlet end to the slotted nozzle 135. In the first section 200, the internal section narrows towards the ball valve 160. The second section 210 then expands outward towards the third section 220. In the third section 220, the internal section narrows towards the outlet end. The internal section of the slotted nozzle 135 further narrows. All of these are configured to form a water spray or water wall ejected from the slotted nozzle 135.

[0024] In another embodiment, Figure 11A unitary, single-mold spray nozzle 300 is shown. The nozzle includes a body 305 extending from an inlet end 310 to an outlet end 315. The body 305 has a hollow cavity 320 from the inlet end to the outlet end to create a continuous inner section 322. The inlet end 310 includes an internal thread 325 for attachment to a liquid source. The inlet end 310 has an inlet ring 330 positioned above the internal thread, wherein the inlet ring 330 extends toward the centerline of the inner section 322. The outlet end 315 includes a pair of slotted nozzles 335 with slots. The slotted nozzles 335 are in fluid communication with the inner section 322. The pair of slotted nozzles 335 taper toward the slots in a narrowing configuration to increase the pressure of the liquid during spraying.

[0025] The entire structure (including the handle and ball valve) is monomold-molded from a semi-rigid material such as plastic, polypropylene, or thermoplastic rubber. This prevents the use of metals that could scratch the surface of the object being painted. Furthermore, because the structure is made of plastic or polypropylene, gaskets are not required.

[0026] As can be observed from the foregoing and as stated above, many variations and modifications can be made without departing from the spirit and scope of the novel concept of this utility model. It should be understood that this is not intended, nor should it be inferred, as any limitation on the specific methods and apparatus shown herein. Of course, the appended claims are intended to cover all such modifications falling within the scope of the claims.
