Description

Technical Field

[0001] This utility model belongs to the field of cleaning device technology, and relates to a high-pressure nozzle and a cleaning device having the nozzle. Background Technology

[0002] In the current field of plastic nozzle technology, nozzles are typically manufactured using a single-structure, one-piece molding process. This type of one-piece molded plastic nozzle has several drawbacks and limitations. First, because its manufacturing process is one-piece molding, the size of the nozzle's spray holes is severely limited by the mold process, making it difficult to achieve smaller orifice diameters.

[0003] Because of the limitations of the molded nozzle's spray hole structure, if the diameter of the spray hole is too small, needle breakage is likely to occur. This greatly limits the application of the nozzle in some scenarios that require high water pressure or fine spraying.

[0004] Secondly, the multiple nozzles contained within the spray head also have numerous quality issues. These nozzles have large orifice diameters, which cannot meet the demands of high-pressure or concentrated water flow, thus affecting the cleaning or spraying effect of the spray head to some extent. Furthermore, the edges of the nozzle's tail (inlet) and head (outlet) are not smooth or regular, exhibiting roughness and burrs.

[0005] Unevenness and burrs at the nozzle tip edge can affect the smoothness of water flow into the nozzle, causing water turbulence and reducing nozzle efficiency. Furthermore, roughness and burrs at the nozzle head not only affect the water spray pattern but can also damage the surface of the object being cleaned or sprayed. Over time, these burrs may break off and mix into the water flow, clogging other components or affecting the overall performance of the nozzle. This single-structure, one-piece molded plastic nozzle can no longer meet the increasingly demanding market requirements for nozzle performance and quality, urgently necessitating a new nozzle structure and manufacturing process to address these issues.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. It should be understood that this application is not limited to the exemplary embodiments disclosed herein. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] In the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0022] Please see Figures 1-2 In this embodiment of the present invention, a novel high-pressure nozzle includes: a nozzle body 1, the front end of the nozzle body 1 being a nozzle hole surface, and a plurality of uniformly arranged nozzle holes 11 formed on the nozzle hole surface, which can uniformly cover the area to be cleaned.

[0023] In order to increase the spray pressure of the water flow, each nozzle 11 is equipped with a pressure boosting nozzle 12 with a small water outlet diameter. According to the principles of fluid mechanics, under the same water pressure input, the smaller orifice diameter can increase the water flow speed, thereby increasing the water pressure and allowing users to obtain a better rinsing effect, effectively solving the defect of insufficient rinsing force of existing nozzles.

[0024] Furthermore, the depth of the nozzle 11 is greater than the structural length of the booster nozzle 12, so that the outlet of the booster nozzle 12 is lower than the opening plane of the nozzle 11; and the nozzle 11 of the nozzle body 1 has an inclined concave structure; so that the nozzle body 1 can wrap around the nozzle; when in use, this structural design changes the flow direction and shape of the water after it is sprayed out of the nozzle, so that the water will not splash everywhere when it is sprayed out, thus improving the user experience.

[0025] Preferably, the pressure boosting nozzle 12 is made of one of the following materials: metal, plastic, or ceramic. Among them, the pressure boosting nozzle 12 made of metal can withstand higher pressure and wear, and is suitable for long-term use or use in high-pressure cleaning scenarios. The pressure boosting nozzle 12 made of plastic has a lower cost and is suitable for general cleaning scenarios where the pressure requirement is not high. The pressure boosting nozzle 12 made of ceramic has good chemical stability and can be used in special chemical liquid cleaning applications, avoiding damage due to chemical corrosion.

[0026] Furthermore, the nozzle body 1 is made of plastic, and the booster nozzle 12 is installed in the nozzle hole 11 of the nozzle body 1 by insert injection molding. In order to improve the installation stability of the booster nozzle 12, a plurality of concave and convex grooves 13 are formed in the outer wall of the booster nozzle 12 and the inner wall of the nozzle hole 11; and the booster nozzle 12 and the concave and convex grooves 13 in the nozzle hole 11 are staggered. The booster nozzle 12 is installed and fixed in the nozzle hole 11 by the cooperation between the concave and convex grooves 13 (the protrusion of one set of concave and convex grooves 13 is embedded into the groove of another set to achieve installation).

[0027] This utility model also provides a cleaner with a high-pressure nozzle, including the above-mentioned novel high-pressure nozzle, which includes: a cleaner body 4, the cleaner body 4 including: a water tank, a battery, a water supply element (pump and motor), a nozzle 3 and a nozzle rod 2.

[0028] The water tank stores the liquid needed for cleaning, and the battery provides power to the entire system, enabling the cleaner to be used in various situations.

[0029] The pump and motor in the water supply unit work together. The motor provides power to the pump, enabling it to draw liquid from the water tank and pressurize it. The pressurized liquid is then delivered to the nozzle 1 on the spray bar 2 through the pipe and nozzle 3. The presence of the spray bar 2 and nozzle 3 ensures that the liquid is accurately delivered to the nozzle 1 and sprayed out. Users can operate the cleaner to spray the liquid from the nozzle 1 to clean the objects that need cleaning.
