Description

Technical Field

[0001] This utility model relates to the field of high-pressure cleaning technology, specifically to a cleaning and disinfection nozzle and a high-pressure water gun. Background Technology

[0002] High-pressure cleaning equipment typically includes a power unit, a high-pressure pump, a high-pressure hose, and a high-pressure water gun. The power unit drives the high-pressure pump to generate high-pressure water, which is then delivered through the high-pressure hose to the high-pressure water gun and sprayed out through a nozzle at the front of the gun to rinse the surface of objects, removing dirt and grime. In some applications, chemicals, such as cleaning agents or disinfectants, are sometimes added to the incoming water to enhance the cleaning or disinfection effect.

[0003] The high-pressure water guns in existing cleaning and disinfection systems are usually threaded to a direct-jet round-hole nozzle, which comes in two shapes: large round hole and small round hole.

[0004] The direct injection round orifice nozzle has the following technical problems:

[0005] Large-aperture nozzles have a larger outlet cross-section, resulting in a greater pressure drop, shorter spray distance, greater cleaning limitations, insufficient foaming of the cleaning solution, low cleaning efficiency, and waste of cleaning solution. Small-aperture nozzles have a smaller outlet cross-sectional area and a smaller spray surface, resulting in longer cleaning time, increased cleaning solution consumption, and cost waste. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a cleaning and disinfection nozzle and a high-pressure water gun, which can provide better spray force and larger spray area, improve cleaning efficiency, and save on chemical costs.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A cleaning and disinfection nozzle includes a nozzle body, which includes a first spray body and a second spray body.

[0009] The first nozzle is provided with multiple first teeth in sequence, and the second nozzle is provided with multiple second teeth in sequence;

[0010] Multiple first tooth profiles and multiple second tooth profiles are arranged opposite to each other;

[0011] A gap is left between the multiple first teeth and the multiple second teeth to allow liquid to pass through;

[0012] The gap extends in a wavy shape from one end of the nozzle body to the other end of the nozzle body;

[0013] The gap between the first tooth profile and the second tooth profile has various specifications.

[0014] Furthermore, the crests of the first tooth shape are opposite to the crests of the second tooth shape.

[0015] Furthermore, the crest of the first tooth is opposite to the trough of the second tooth.

[0016] Furthermore, both the first and second tooth profiles are straight tooth profiles.

[0017] Furthermore, both the first and second tooth profiles are arc-shaped tooth profiles.

[0018] A high-pressure water gun, including the aforementioned cleaning and disinfection nozzle.

[0019] In summary, this utility model has the following advantages:

[0020] When the nozzle of this invention is used on a high-pressure water gun, the high-pressure water is sprayed out from the gap between multiple first and second teeth, resulting in strong friction between the high-pressure water and the multiple first and second teeth, thus generating richer foam. Compared with the existing direct-spray round-hole nozzle, this greatly enhances the foaming effect of the disinfectant, improves the cleaning and disinfection performance, and increases the utilization rate of the disinfectant. By selecting the appropriate gap specification between the first and second teeth as needed, the nozzle can maintain good spray force under different spray distance requirements. Since the gap extends in a wavy shape from one end of the nozzle body to the other end, it can increase the spray area while maintaining good spray force, thereby improving cleaning efficiency and saving disinfectant costs.

[0029] This invention addresses the problems of low cleaning efficiency and cost waste caused by insufficient spray distance and weak chemical foaming during the cleaning process by optimizing the nozzle of a high-pressure water gun. The most suitable nozzle can be selected based on the specific application scenario.

[0030] The present invention will now be described in further detail.

[0031] like Figures 1-6 As shown, a cleaning and disinfection nozzle includes a nozzle body 1, which has an external thread and can be threaded onto the front end of a high-pressure water gun.

[0032] The nozzle body 1 includes a first spray body 11 and a second spray body 12, which can be integrally formed and manufactured.

[0033] The first nozzle 11 is provided with a plurality of first teeth 111 in sequence, and the second nozzle 12 is provided with a plurality of second teeth 121 in sequence;

[0034] Multiple first tooth profiles 111 and multiple second tooth profiles 121 are arranged opposite to each other;

[0035] A gap 13 is provided between the plurality of first tooth profiles 111 and the plurality of second tooth profiles 121 to allow liquid to pass through;

[0036] The gap 13 extends in a wavy shape from one end of the nozzle to the other end of the nozzle;

[0037] The gap 13 between the first tooth profile 111 and the second tooth profile 121 has various sizes.

[0038] Existing technologies typically use direct-jet round-hole nozzles on high-pressure water guns. When high-pressure water is sprayed from the direct-jet round-hole nozzle, the contact friction and contact range between the high-pressure water and the nozzle are relatively small, making it difficult to generate abundant foam. As a result, the foaming effect of the disinfectant is insufficient, and the cleaning and disinfection performance of the disinfectant cannot be fully utilized. The utilization rate of the disinfectant needs to be improved.

[0039] When the nozzle of this invention is used on a high-pressure water gun, when high-pressure water is sprayed out from the gap 13 between multiple first teeth 111 and multiple second teeth 121, the high-pressure water undergoes strong friction with the multiple first teeth 111 and multiple second teeth 121, thereby generating richer foam. Compared with the existing direct-spray round-hole nozzle, this greatly enhances the foaming effect of the solution, improves the cleaning and disinfection performance of the solution, and increases the utilization rate of the solution. By selecting the appropriate gap 13 specification between the first teeth 111 and the second teeth 121 as needed, the nozzle can maintain a good spray force under different spray distance requirements. Since the gap 13 extends in a wavy shape from one end of the nozzle body 1 to the other end of the nozzle body 1, the spray area is increased compared with the dot nozzle. Therefore, while maintaining a good spray force, the spray area can be increased, cleaning efficiency can be improved, and the cost of the solution can be saved.

[0040] The relative arrangement of the plurality of first tooth profiles 111 and the plurality of second tooth profiles 121 in this utility model includes two scenarios: the crest of the first tooth profile 111 is opposite to the crest of the second tooth profile 121, and the crest of the first tooth profile 111 is opposite to the trough of the second tooth profile 121.

[0041] The first tooth profile 111 and the second tooth profile 121 of this utility model include two cases, namely:

[0042] Both the first tooth profile 111 and the second tooth profile 121 are straight tooth profiles, such as Figures 1-4 As shown, multiple straight teeth connected in sequence form a serrated shape, resulting in stronger friction with high-pressure water and producing more abundant foam. Alternatively,

[0043] Both the first tooth profile 111 and the second tooth profile 121 are arc-shaped tooth profiles, such as Figure 5 , Figure 6 As shown, multiple arc-shaped teeth are connected in sequence to form a wave shape, which can generate abundant foam from high-pressure water and reduce friction compared to a sawtooth shape, thus extending service life. In this application, each nozzle body 1 has 4 teeth on its first tooth 111 and second tooth 121, and the specific number of teeth can be adjusted as needed.

[0044] Example 1

[0045] By employing a linear toothed nozzle and connecting it to the cleaning and disinfection system, the cleaning and disinfectant can be sprayed more evenly onto the equipment surface, improving cleaning efficiency. When the cleaning and disinfectant passes through the nozzle, it experiences strong friction against the linear toothed surface of the nozzle, enhancing the foaming effect of the cleaning agent, increasing its volume, and significantly expanding the cleaning area.

[0046] Meanwhile, the different spacing of the nozzles 13 can be applied to different scenarios; First, when it is necessary to clean stubborn stains on large equipment and the distance is relatively close, select the nozzle with a larger spacing of 13 to spray the cleaning agent evenly onto the cleaning surface, soften the stains, and finally rinse; Second, when it is necessary to clean local stains on equipment and the distance is relatively far, select the nozzle with a smaller spacing of 13 to spray the cleaning agent evenly onto the equipment surface, soften the stains, and finally rinse.

[0047] Example 2

[0048] Using an arc-shaped toothed nozzle, the nozzle is connected to the cleaning and disinfection system to spray the cleaning agent onto the equipment surface. The cleaning agent can be sprayed in a streamlined pattern, which can be used for cleaning stains on large equipment at close range, as well as surface cleaning of buildings on site. The spray pressure of the cleaning agent is relatively small, but the spray area is large, which can enable the cleaning agent to quickly cover the surface of the object to be cleaned and improve cleaning efficiency.

[0049] This invention optimizes the nozzle shape to spray the cleaning and disinfecting agent more evenly while maintaining a certain impact force, which can better remove stains, reduce waste of cleaning solution, improve cleaning efficiency, and save costs.

[0050] A high-pressure water gun, with the aforementioned cleaning and disinfection nozzle at its front end, possesses at least the advantages of the aforementioned cleaning and disinfection nozzle.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
