[0004] The technical solution adopted by this utility model to solve its technical problem is: a cleaning nozzle, installed in the spray bar body, including a nozzle body, the nozzle body having a water inlet channel; and also including an elastic water outlet component, the elastic water outlet component being installed on the nozzle body and having a water outlet hole, the water outlet hole communicating with the water inlet channel, the nozzle body also having an anti-clogging structure movably disposed between the water outlet hole and the water inlet channel.

[0005] In a preferred embodiment, the anti-clogging structure includes an anti-clogging component. The nozzle body has a movable cavity between the water outlet and the water inlet channel, which connects the water outlet and the water inlet channel. The anti-clogging component is movably disposed in the movable cavity and can be partially inserted into the water outlet. When water enters the water inlet channel, the anti-clogging component is driven by the water flow to move in the direction of insertion into the water outlet. When water enters the water inlet channel, the anti-clogging component resets in the direction of withdrawal from the water outlet.

[0006] In a preferred embodiment, the anti-clogging component includes a base with an anti-clogging post corresponding to the water outlet. The base is located in the movable cavity, and the free end of the anti-clogging post extends into the water outlet. The outer diameter of the anti-clogging post is smaller than the inner diameter of the water outlet.

[0007] In a preferred embodiment, the nozzle body has a pressurization channel between the water inlet channel and the anti-clogging structure. One end of the pressurization channel is connected to the water inlet channel, and the other end is connected to the water outlet. The water passage area of ​​the pressurization channel is smaller than that of the water inlet channel.

[0008] In a preferred embodiment, the inner diameter of the water outlet gradually decreases along its water outlet direction; the elastic water outlet element is made of silicone.

[0009] In a preferred embodiment, the top surface of the nozzle body is provided with a mounting groove communicating with the water inlet channel, and the elastic water outlet is disposed in the mounting groove.

[0010] In a preferred embodiment, a fixing cover is also included, which is connected to the opening of the mounting groove and covers the elastic water outlet, and the fixing cover is provided with a clearance hole corresponding to the water outlet.

[0011] In a preferred embodiment, the outer peripheral surface of the elastic water outlet is provided with at least one limiting rib, and the elastic water outlet and the mounting groove are interference-fitted by the limiting rib.

[0012] In a preferred embodiment, the fixed cover is provided with an embedded rib extending in the direction of the elastic water outlet, and the elastic water outlet is provided with an embedded groove corresponding to the embedded rib, and the embedded rib and the embedded groove are fitted together.

[0013] This utility model also provides a spray bar assembly, including a spray bar body and a mounting base. The spray bar body is telescopically connected to the mounting base. It also includes a cleaning nozzle of this utility model, which is installed at the extended end of the spray bar body.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model includes an elastic water outlet component that can elastically deform under the impact of water flow or external rubbing, effectively squeezing out tiny impurities or scale adhering to the periphery of the water outlet, achieving a self-cleaning function. Furthermore, the nozzle body is equipped with an anti-clogging structure to prevent the water outlet from becoming blocked, further preventing the accumulation of impurities or scale at the water outlet. Through the combination of the elastic water outlet component and the anti-clogging structure, this utility model significantly reduces the probability of water outlet blockage, avoiding the problems of reduced cleaning effect or interrupted water spray due to blockage, greatly reducing the frequency of cleaning and maintenance, and extending the service life of the cleaning nozzle.

[0016] 2. The anti-clogging structure includes an anti-clogging component that is movably installed in the movable cavity. When water flows through the inlet channel, the water flow pushes the anti-clogging component towards the outlet hole, squeezing out the impurities blocking the outlet hole. After the water is cut off, the anti-clogging component returns to the movable cavity by its own restoring force, restoring its initial state. The structure is simple, requires no external power source or manual intervention, and has good self-cleaning ability and reliability.

[0017] 3. The nozzle body has a pressure boosting channel between the water inlet channel and the anti-clogging structure. The water flow area of ​​the pressure boosting channel is smaller than that of the water inlet channel, which can increase the pressure of the water flow. The high-pressure water flow can squeeze the elastic water outlet to wash away impurities from the elastic water outlet, further preventing impurities or scale from accumulating at the water outlet.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the cleaning nozzle and spray bar assembly of the present invention is not limited to the embodiments. Attached Figure Description

"And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. In the description of this utility model, unless otherwise explicitly specified and limited, terms such as "installed," "equipped with," and "connected" should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please see Figures 1-5 As shown, this utility model discloses a cleaning nozzle installed inside a spray bar body 5. The nozzle body 1 includes a nozzle body 1 with a water inlet channel 11. It also includes an elastic water outlet component 2, mounted on the nozzle body 1 and equipped with a water outlet hole 21 connected to the water inlet channel 11. The nozzle body 1 further includes an anti-clogging structure movably disposed between the water outlet hole 21 and the water inlet channel 11. The elastic water outlet component 2 can undergo elastic deformation under water flow impact or external rubbing, effectively squeezing out tiny impurities or scale adhering to the periphery of the water outlet hole 21, achieving a self-cleaning function. Furthermore, the anti-clogging structure on the nozzle body 1 further prevents impurities or scale from accumulating at the water outlet hole 21. The combination of these two features significantly reduces the probability of clogging at the water outlet hole 21, avoiding problems such as decreased cleaning effect or interrupted water spraying due to clogging, greatly reducing the frequency of cleaning and maintenance, and extending the service life of the cleaning nozzle.

[0029] Preferably, the elastic water outlet component 2 is made of silicone, specifically food-grade silicone, which meets international standards, is safe and non-toxic, and suitable for direct contact with the human body. Silicone has good elastic recovery ability, and can quickly return to its original shape under rubbing or water pressure. It has excellent chemical stability, strong resistance to chemicals such as acids, alkalis, and salts, and is not corroded by detergents. It also maintains stable performance under the influence of environmental factors such as ultraviolet rays and high temperatures, is not prone to aging, and has a long service life. At the same time, it has low surface tension and good hydrophobic properties, which can reduce scale adhesion and further reduce the risk of clogging.

[0030] The number of water outlet holes 21 of the flexible water outlet component 2 is multiple, and the number, size and distribution can be optimized according to cleaning needs to ensure cleaning effect while reducing the risk of clogging.

[0031] The anti-clogging structure includes an anti-clogging component 3. A movable cavity 12 is provided inside the nozzle body 1 between the water outlet 21 and the water inlet channel 11. This movable cavity 12 connects the water outlet 21 and the water inlet channel 11. Specifically, the elastic water outlet component 2 is installed on the top of the nozzle body 1, and the movable cavity 12 is coaxially arranged with the water outlet 21. The anti-clogging component 3 is movably disposed within the movable cavity 12 and can be partially inserted into the water outlet 21. Figure 3 As shown, when water enters the inlet channel 11, the anti-clogging component 3 is driven by the water flow to move in the direction of insertion into the outlet hole 21 (i.e., upward) to squeeze out the impurities clogging the outlet hole 21; as Figure 5 As shown, when water intake stops in the water inlet channel 11, the anti-blocking component 3 returns to its original position by falling back towards the outlet hole 21 under its own weight. In other embodiments, the anti-blocking component can also be reset by providing an elastic element.

[0032] Specifically, the anti-clogging component 3 includes a base 31, which has an anti-clogging post 32 corresponding to the water outlet 21. The base 31 is located in the movable cavity 12, and the free end of the anti-clogging post 32 extends into the water outlet 21. The outer diameter of the anti-clogging post 32 is smaller than the inner diameter of the water outlet 21 to prevent the anti-clogging post 32 from being stuck after being inserted into the water outlet 21.

[0033] The nozzle body 1 has a pressure boosting channel 13 between the water inlet channel 11 and the anti-clogging structure. One end of the pressure boosting channel 13 is connected to the water inlet channel 11, and the other end is connected to the water outlet 21. The water flow area of ​​the pressure boosting channel 13 is smaller than that of the water inlet channel 11, thereby increasing the water flow pressure, which facilitates the movement of the anti-clogging component 3. In addition, the high-pressure water flow can also squeeze the elastic water outlet component 2 to wash away impurities, further preventing impurities or scale from accumulating at the water outlet 21.

[0034] In this embodiment, the inner diameter of the water outlet 21 gradually decreases along its outlet direction, and its cross-section is triangular. This not only enhances the impact force of the water flow but also effectively drains residual water after the water flow stops, reducing scale buildup. However, this is not the only embodiment. In other embodiments, the cross-section of the water outlet can also be elliptical, etc.

[0035] The top surface of the nozzle body 1 is provided with a mounting groove 14 communicating with the water inlet channel 11. The elastic water outlet component 2 is disposed in the mounting groove 14 for easy disassembly and replacement. The outer peripheral surface of the elastic water outlet component 2 is provided with at least one limiting rib 22. The elastic water outlet component 2 and the mounting groove 14 are interference-fitted by the limiting rib 22 to prevent the elastic water outlet component 2 from falling off. However, the connection method between the elastic water outlet component 2 and the nozzle body 1 is not limited to this. In other embodiments, the elastic water outlet component 2 and the nozzle body 1 can be connected by threads.

[0036] This utility model also includes a fixing cover 4, which is connected to the opening of the mounting groove 14 and covers the elastic water outlet 2. The fixing cover 4 is provided with a clearance hole 41 corresponding to the water outlet 21. The fixing cover 4 is provided with an embedded rib 42 extending in the direction of the elastic water outlet 2. The elastic water outlet 2 is provided with an embedded groove 23 corresponding to the embedded rib 42. The embedded rib 42 and the embedded groove 23 are fitted together. The side of the fixing cover 4 away from the elastic water outlet 2 abuts against the spray bar body 5.

[0037] The nozzle body 1 can be made of corrosion-resistant and aging-resistant ABS or PP plastic. A filter device can be installed at the water inlet end of the water inlet channel 11 to intercept large particulate impurities.

[0038] Please see Figures 1-6 As shown, a spray bar assembly of the present invention includes a spray bar body 5 and a mounting base 6. The spray bar body 5 is telescopically connected to the mounting base 6 and also includes the aforementioned cleaning nozzle. The cleaning nozzle is installed at one of the extended ends of the spray bar body 5, and the spray bar body 5 is provided with a water outlet 51 corresponding to the water outlet hole 21.

[0039] The spray bar assembly of this utility model, regarding the structure and working principle of the cleaning nozzle, please refer to the previous description, which will not be repeated here.

[0040] The cleaning nozzle and spray bar assembly of this utility model are identical to or can be implemented using existing technologies for the parts not described herein.

[0041] The above embodiments are only used to further illustrate a cleaning nozzle and spray bar assembly of the present invention. However, the present invention is not limited to the embodiments.
