Description

Technical Field

[0001] This utility model belongs to the field of atomizing nozzle technology, specifically relating to a protective dashboard wax spray anti-clogging atomizing nozzle structure. Background Technology

[0002] In the fields of car interior care and furniture surface maintenance, dashboard wax spray has become a commonly used tool due to its convenience and efficiency. The performance of its core component, the atomizing nozzle, directly determines the product's effectiveness. However, because dashboard wax liquid has a complex composition, it usually contains wax particles, silicone oil, solvents, and functional solid additives (such as silica particles to enhance gloss and anti-slip fillers). During storage, these components may condense due to temperature changes or solvent evaporation, forming particulate impurities of varying sizes. When spraying, these impurities flow with the liquid through the nozzle filter and gradually accumulate on the filter surface and in the pores, forming a dense clogging layer.

[0003] Currently, when the nozzle filter screen becomes clogged, it is usually disassembled and cleaned to avoid affecting the nozzle's performance. However, most existing filters are embedded inside the nozzle, requiring multiple steps such as disassembling the nozzle housing and separating the liquid inlet pipe to remove and clean them. This process is not only time-consuming and labor-intensive, but may also damage the sealing components due to improper operation, leading to leakage problems after cleaning. Furthermore, frequent manual disassembly and cleaning can easily cause wear on the nozzle installation position, resulting in loosening of the nozzle and affecting its service life. Utility Model Content

[0004] The purpose of this invention is to provide a protective dashboard wax spray anti-clogging atomizing nozzle structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective dashboard wax spray anti-clogging atomizing nozzle structure, comprising:

[0006] A connecting tube, one end of which is threaded to a nozzle, and an arc-shaped filter screen for filtering impurities in the dashboard wax liquid is provided at the threaded connection between the connecting tube and the nozzle.

[0007] A cleaning component, located inside a connecting pipe, is used to clean impurities filtered by an arc-shaped filter screen. The cleaning component includes a flushing pipe and a cleaning pipe. The flushing pipe is located on the connecting pipe, and the cleaning pipe has several sets, all located inside nozzles. The arc-shaped filter screen is flushed by adding flushing water into the flushing pipe, so that the flushed impurities flow out of the nozzles from the cleaning pipes with the water flow.

[0008] Preferably, one end of the connecting tube has several annular openings, one end of the cleaning tube extends to the openings, and the other end passes through the nozzle and is threadedly connected to the sealing cap.

[0009] Preferably, one end of the flushing pipe is connected to a connector, and the connector has an installation groove inside.

[0010] Preferably, a filter screen is fixed in the mounting groove by screws, and a lifting rod is connected to the center of the top of the filter screen.

[0011] Preferably, one end of the connecting pipe is provided with an external thread, and the top of the nozzle is provided with an internal thread. The connecting pipe is threadedly connected to the internal thread inside the nozzle through the external thread.

[0012] Preferably, a sealing ring is provided at the threaded connection between the connecting pipe and the nozzle.

[0013] Preferably, the connector also has an internal thread, and the connector is connected to a sealing cap via the internal thread.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) Flushing water is injected into the connecting pipe through the flushing pipe. The water flow can directly impact the surface of the arc-shaped filter screen, washing away the accumulated impurities. The impurities can be discharged from the nozzle through the cleaning pipe with the water flow. There is no need to disassemble the nozzle shell or filter screen assembly, which greatly reduces maintenance costs and operation difficulty, and avoids the problems of component wear or sealing failure caused by traditional manual disassembly.

[0016] (2) The arc-shaped filter screen has a curved structure, which increases the filtration area and guides the liquid to flow evenly. The filter screen in the connector can intercept impurities in the rinsing water, prevent secondary pollution of the nozzle, and ensure that the rinsing process does not affect the subsequent spray quality.

[0017] (3) The connecting pipe and the nozzle are connected by external and internal threads. The connecting pipe and the nozzle can be quickly disassembled and assembled when maintaining the internal parts of the nozzle. The sealing ring set at the connection between the connecting pipe and the nozzle can seal the connection to prevent the leakage of the panel wax liquid or rinsing water and ensure the sealing of the structure.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-4 The protective dashboard wax spray anti-clogging atomizing nozzle structure shown includes:

[0025] A connecting pipe 1 is provided, with a nozzle 2 threadedly connected to one end of the connecting pipe 1. An arc-shaped filter screen 3 is provided at the threaded connection between the connecting pipe 1 and the nozzle 2 for filtering impurities in the dashboard wax liquid.

[0026] A cleaning component is provided inside the connecting pipe 1 and is used to clean the impurities filtered by the arc-shaped filter screen 3. The cleaning component includes a flushing pipe 4 and a cleaning pipe 5. The flushing pipe 4 is provided on the connecting pipe 1, and the cleaning pipe 5 is provided in several groups and is provided inside the nozzle 2. The arc-shaped filter screen 3 is flushed by adding flushing water into the flushing pipe 4 so that the flushed impurities flow out of the nozzle 2 from the cleaning pipe 5 with the water flow.

[0027] One end of the connecting pipe 1 has several annular openings 6. One end of the cleaning pipe 5 extends to the openings 6, and the other end passes through the nozzle 2 and is threadedly connected to the sealing cap 7.

[0028] One end of the flushing pipe 4 is connected to a connector 8, and the connector 8 has an installation groove 9 inside.

[0029] The filter screen 11 is screwed into the mounting slot 9 by screws 10, which are made of stainless steel to prevent rust. A lifting rod 16 is connected to the top center of the filter screen 11. When the filter screen 11 is clogged or worn due to long-term use, and needs to be cleaned or replaced, the screws 10 can be loosened with a tool, and the lifting rod 16 can be manually pulled to remove the filter screen 11 from the mounting slot 9 for cleaning or replacement, so that the filter screen 11 maintains a good filtration effect.

[0030] One end of the connecting pipe 1 is provided with an external thread 12, and the top of the nozzle 2 is provided with an internal thread 13. The connecting pipe 1 is threadedly connected to the nozzle 2 through the external thread 12 and the internal thread 13. The threaded connection facilitates the installation, disassembly and replacement of the nozzle 2. When the arc-shaped filter screen 3 is worn after long-term use, the nozzle 2 can be loosened and removed from the connecting pipe 1, so that the arc-shaped filter screen 3 between the connecting pipe 1 and the nozzle 2 can be replaced, so that the arc-shaped filter screen 3 can maintain a good filtration effect.

[0031] A sealing ring 14 is provided at the threaded connection between the connecting pipe 1 and the nozzle 2. The sealing ring 14 is made of rubber material. When the threads of the connecting pipe 1 and the nozzle 2 are tightened, it can be deformed under pressure, fill the thread gap and stick to the contact surface to form an elastic sealing film, which can effectively prevent the leakage of dashboard wax liquid and rinsing water through the thread gap between the connecting pipe 1 and the nozzle 2.

[0032] The connector 8 is also provided with an internal thread 13. The connector 8 is threadedly connected to a sealing cap 15 through the internal thread 13. In the non-cleaning state, the sealing cap 15 is tightly screwed into the connector 8 through the thread to form a fully enclosed interface, preventing external dust, water vapor or foreign objects from entering the nozzle 2 through the inlet of the flushing pipe 4.

[0033] The protective dashboard wax spray anti-clogging atomizing nozzle structure has one end of the connecting pipe 1 connected to the dashboard wax spray can, and the dashboard wax liquid in the dashboard wax spray can enter from the inlet of the connecting pipe 1 and flow axially to the arc-shaped filter screen 3. Because the arc-shaped filter screen 3 is set in an arc shape, the liquid forms a dispersed impact state instantly when it comes into contact with the arc-shaped filter screen 3, and large particulate impurities in the dashboard wax liquid (such as wax crystals and additive agglomerates) are intercepted on the surface of the arc-shaped filter screen 3 to prevent clogging of the nozzle 2. The intercepted impurities are naturally gathered towards the bottom of the arc-shaped filter screen 3 (i.e., the bottom of the connecting pipe 1) due to the inertia of the liquid flow and the guiding effect of the curved surface of the arc-shaped filter screen 3.

[0034] The filtered pure panel wax liquid flows into the nozzle 2 through the pores of the arc-shaped filter screen 3. Under the pressure of the panel wax spray can, the panel wax liquid entering the nozzle 2 rushes at high speed into the vortex chamber in the nozzle head and forms a high-speed rotating liquid film. Under the action of centrifugal force, it breaks into fine droplets and is sprayed out from the nozzle 2 to form uniform mist droplets, which are sprayed onto the surface of the workpiece.

[0035] As the spray continues, impurities will gradually accumulate on the arc-shaped filter screen 3 and at the bottom of the connecting pipe 1, forming an impurity layer that clogs the arc-shaped filter screen 3. At this point, the equipment can be stopped, and the sealing cap 7 can be manually loosened to allow the panel wax liquid flowing into the cleaning pipe 5 to flow out of the cleaning pipe 5 and be collected in the external collection box, thus avoiding waste of the panel wax liquid. Then, the sealing cap 15 on the connector 8 can be unscrewed, and the flushing medium (such as clean water) can be injected into the flushing pipe 4 through the connector 8. The filter screen 11 at the inlet of the flushing pipe 4 first intercepts the impurities in the medium. To ensure the purity of the rinsing medium, the rinsing medium flows into the connecting pipe 1 along the rinsing pipe 4 and rinsing the surface of the arc-shaped filter screen 3 and the bottom of the connecting pipe 1. The rinsing force can loosen the impurities accumulated on the surface of the arc-shaped filter screen 3 and the bottom of the connecting pipe 1, and flow with the water flow to the opening 6, and then flow into the cleaning pipe 5 through the opening 6 and out of the cleaning pipe 5, thereby completing the cleaning of the arc-shaped filter screen 3. After rinsing, the sealing cap 7 and the sealing cover 15 can be tightened and reset to facilitate the normal operation of the nozzle 2.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
