Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a device for cleaning and removing dust from the inner wall of air conditioning copper pipes. Background Technology

[0002] As a crucial component of modern buildings, air conditioning systems are prone to accumulating dust, grease, bacteria, and other contaminants on their internal copper pipes during long-term operation. This grime not only significantly reduces the cooling (heating) efficiency of the air conditioner and increases energy consumption, but also becomes a breeding ground for bacteria, posing a potential threat to indoor air quality and human health. Therefore, regular and thorough cleaning of the inner walls of the air conditioning copper pipes is of paramount importance.

[0003] However, existing methods and devices for cleaning the inner walls of copper pipes generally have some technical shortcomings. On the one hand, when cleaning narrow, complex, and winding air conditioning copper pipes, existing cleaning nozzles or tools often lack effective guiding and buffering mechanisms, easily impacting the inner wall of the copper pipe when passing through bends, causing damage. Simultaneously, because they cannot effectively flush against the inner wall of the bends, dirt in these areas is difficult to remove completely, resulting in an unsatisfactory overall cleaning effect. On the other hand, after wet flushing, a large amount of cleaning fluid and water remains inside the copper pipes. Existing water removal methods often cannot completely and efficiently remove these liquids, causing water to remain inside the pipes for extended periods. If the water is not completely removed, it not only accelerates the oxidation and corrosion of the copper pipes but also provides conditions for the regrowth of microorganisms, thus preventing the cleaning work from achieving the expected dry and dust-free effect and even causing new problems. Furthermore, existing cleaning equipment also has room for improvement in terms of mobility and ease of operation, limiting the flexibility and efficiency of cleaning operations.

[0004] Therefore, this utility model proposes a dust removal device for cleaning the inner wall of air conditioning copper pipes to address the shortcomings of existing technologies. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cleaning and dust removal device for the inner wall of air conditioning copper pipes, which aims to improve the problems of the cleaning nozzles easily damaging the pipe wall at the bends of the copper pipes, incomplete cleaning, and difficulty in effectively removing residual moisture after cleaning in the existing air conditioning copper pipe cleaning and dust removal devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The air conditioning copper pipe inner wall cleaning and dust removal device includes a base, rollers, push rods, flushing components, and water removal components. The flushing components include a water tank, water pump, water pipes, hollow flexible hoses, five-hole nozzles, conical guide heads, springs, and grooves. The water removal components include a pressure pump, exhaust valve, air pipes, sponges, and double-layer soft rubber scrapers.

[0007] A water pump is connected to a water tank via a water pipe and to a five-hole nozzle via a hollow flexible hose. The five-hole nozzle has multiple spray holes. A groove is formed in the center of the five-hole nozzle, and the two ends of a spring are fixedly connected to a conical guide head and the inner wall of the groove, respectively, allowing the conical guide head to slide within the groove. An air pump is connected to an air pipe via an exhaust valve, and the end of the air pipe is equipped with a sponge and a double-layered soft rubber scraper. This combination achieves effective flushing of the inner wall of the copper pipe during cleaning, non-destructive guidance at bends, and multiple efficient removals of moisture from the inside of the copper pipe after cleaning.

[0008] Preferably, the surface of the tapered guide head has a beveled structure, which can act as a guide when it comes into contact with the bend in the inner wall of the copper tube, helping the five-hole nozzle to pass smoothly through the bend area.

[0009] Preferably, the flushing and dewatering components can move along with the base and rollers, facilitating the overall movement and positioning of the device.

[0010] Preferably, the flushing component and the dewatering component are arranged side by side on the base to optimize the device layout and make the structure more compact.

[0011] Preferably, the hollow flexible hose has a flexible structure so that it can be flexibly inserted into the air conditioner copper pipe for cleaning.

[0012] Preferably, the air pipe has a flexible structure so that it can be flexibly inserted into the air conditioner copper pipe for dewatering.

[0013] Preferably, the sponge is placed at the rear end of the double-layer soft rubber scraper to form a composite water removal mode of first scraping and then adsorbing, so as to maximize the water removal effect.

[0014] Preferably, the multiple spray holes of the five-hole nozzle are evenly distributed to ensure that the cleaning liquid is sprayed evenly, covers a wide area, and improves the flushing effect.

[0015] This utility model has the following beneficial effects: 1. In this utility model, the five-hole nozzle adopts a multi-hole spray structure, combined with a groove in the center of the five-hole nozzle, a spring and a tapered guide head that are slidably connected, and the tapered guide head has a beveled surface. This solves the problem in the prior art that it is difficult to thoroughly clean the stains on the inner wall of the air conditioning copper pipe, especially at bends where the pipe wall is easily damaged and difficult to pass through. It achieves the technical effects of significantly improving the cleaning force on the inner wall of the copper pipe, further removing stubborn stains, avoiding direct impact of the nozzle on the inner wall of the copper pipe and causing damage through buffering, and allowing the nozzle to flexibly turn and smoothly pass through the bend area through the guiding effect, thus ensuring the continuity of the cleaning process and non-destructive cleaning.

[0016] 2. In this utility model, by setting up a triple water removal mechanism of high-pressure gas blowing, double-layer soft rubber scraping, and sponge adsorption, the problem of residual moisture after cleaning the inner wall of air conditioning copper pipes in the prior art is difficult to completely remove, which affects the drying effect. It achieves the technical effect of maximizing the water removal effect, ensuring that the inner wall of the copper pipe is completely dry, and avoiding secondary pollution or corrosion caused by water stains.

[0017] 3. In this utility model, by setting rollers at the bottom of the base, setting push rods at the top of the base, and fixing the flushing component and water removal component as a whole on the base, the problem of the cleaning device being inconvenient to move and position and inflexible in operation in the prior art is solved. It achieves the technical effect of making it convenient for cleaning personnel to push smoothly, quickly position and flexibly transfer the equipment, thereby improving work efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figures 1 to 4This utility model provides a device for cleaning and removing dust from the inner wall of air conditioning copper pipes, which aims to solve the problems of low cleaning efficiency, insufficient protection of bends, and difficulty in completely removing liquid residue after cleaning in the prior art.

[0022] like Figure 1 and Figure 2 As shown, the air conditioner copper pipe inner wall cleaning and dust removal device includes a base 1, and a push rod 2, rollers 3, a flushing assembly 4, and a water removal assembly 5 mounted on the base 1. The base 1 serves as the mounting base for the entire device, supporting and connecting all functional components. The push rod 2 is fixedly connected above the base 1 for the user to push the device horizontally. The rollers 3 are located at the bottom of the base 1 and contact the ground to achieve smooth movement of the device. The flushing assembly 4 and the water removal assembly 5 are fixedly connected side by side on the base 1. They are the core components for the device to achieve the cleaning and dust removal function. The flushing assembly 4 is used to spray cleaning liquid onto the inner wall of the air conditioner copper pipe to remove stains, while the water removal assembly 5 is used to remove residual liquid from the inner wall of the copper pipe to ensure that the copper pipe is dry.

[0023] To solve the above-mentioned technical problems, the core of the technical solution in this embodiment is that the flushing component 4 of the air conditioner copper pipe inner wall cleaning and dust removal device is specially designed with a nozzle assembly having buffer and conical guiding functions.

[0024] Please refer to the following carefully. Figure 3 and Figure 4 The core structure will be described in detail below: The hollow hose 44 of the flushing assembly 4 is fixedly connected to a five-hole nozzle 45. The five-hole nozzle 45 has a groove 48 in the center, which extends along the central axis of the five-hole nozzle 45 to form a space for other components to slide. The inner wall of the groove 48 serves as the fixing and sliding mating surface for the spring 47 and the conical guide head 46.

[0025] A tapered guide head 46 is located at the front end of the five-hole nozzle 45. The spring 47 is spiral-shaped, with its two ends fixedly connected to the tapered guide head 46 and the inner wall of the groove 48, respectively. The tapered guide head 46 can slide along the central axis within the groove 48. The spring 47 provides elastic deformation and buffering. The surface of the tapered guide head 46 has a beveled structure, which acts as a guide when it contacts the bend in the inner wall of the copper tube, guiding the five-hole nozzle 45 smoothly through the bend area. The five-hole nozzle 45 has multiple spray holes, which are evenly distributed at the end of the five-hole nozzle 45 for spraying cleaning fluid.

[0026] This sliding engagement structure of the tapered guide head 46 and the spring 47 within the groove 48 ensures that when the five-hole nozzle 45 enters the bend of the copper tube, the tapered guide head 46 can first contact the inner wall of the bend, and the spring 47 will then undergo elastic deformation. Through buffering, it prevents the five-hole nozzle 45 from directly impacting the inner wall of the copper tube and causing damage to the inner wall. At the same time, the inclined structure of the tapered guide head 46 assists the five-hole nozzle 45 in flexibly turning, ensuring the continuity of the cleaning process.

[0027] The power source for driving the hollow hose 44 and the five-hole nozzle 45 to move inside the copper tube can be achieved by manual pushing or other conventional methods by those skilled in the art. Its specific internal structure is well known in the art and will not be described in detail here.

[0028] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, to enable the five-hole nozzle 45 to flexibly pass through the bends in the air conditioning copper pipe and to provide good guidance, the surface of the tapered guide head 46 is designed with a beveled structure. When the tapered guide head 46 contacts the bend in the inner wall of the copper pipe, its bevel can conform to the bend direction, guiding the five-hole nozzle 45 to turn, ensuring the continuity and unobstructed cleaning path.

[0029] As another preferred embodiment, in order to facilitate the movement and placement of the device, the flushing component 4 and the water removal component 5 are fixed as functional modules on the base 1 and can move together with the base 1 and the rollers 3 as they roll. In this way, the cleaning staff can easily push the entire device to any air-conditioned area that needs to be cleaned by using the push rod 2.

[0030] In another preferred embodiment, in order to optimize the overall layout and space utilization of the device, the flushing component 4 and the dewatering component 5 are arranged side by side on the base 1. This arrangement makes the device structure compact and facilitates the operator to quickly switch between the cleaning flushing and dewatering steps.

[0031] As another preferred embodiment, in order to ensure that the cleaning fluid can be smoothly delivered to the depths of the air conditioning copper pipe and effectively flush it, the hollow hose 44 is preferably a flexible structure. This flexible design allows the hollow hose 44 to bend freely and easily pass through various bends of the copper pipe, ensuring that the cleaning fluid can reach every corner of the inner wall of the copper pipe.

[0032] As another preferred embodiment, in order to enable the high-pressure gas and the dewatering component to effectively enter the interior of the air conditioning copper pipe for dewatering, the gas pipe 52 is preferably a flexible structure. This flexible design allows the gas pipe 52 to adapt to the complex internal path of the copper pipe, ensuring that the dewatering component can penetrate into any position of the copper pipe.

[0033] As a further preferred embodiment, in order to maximize the dewatering effect and ensure the inner wall of the copper tube is dry, the sponge 54 is placed at the rear end of the double-layer soft rubber scraper 55. When the air tube 52 enters the copper tube, the double-layer soft rubber scraper 55 first fits tightly against the inner wall of the copper tube and scrapes away most of the residual water stains. Then, the sponge 54 located behind it makes full contact with the tube wall and uses its high water absorption to absorb the trace amount of water that the scraper could not remove, thus achieving secondary dewatering and fine drying.

[0034] As another preferred embodiment, in order to ensure that the cleaning fluid forms a uniform and comprehensive coverage on the inner wall of the copper tube and enhance the flushing force, the multiple spray holes of the five-hole nozzle 45 are designed to be evenly distributed. This evenly distributed spray hole can ensure that the cleaning fluid is sprayed out in a multi-point, equidistant manner, increasing the coverage area of ​​the cleaning fluid and thus effectively removing stubborn stains.

[0035] Working principle: The cleaning staff first holds the push rod 2 on the top of the device with both hands and pushes it forward smoothly in the horizontal direction. With the help of the rolling action of the roller 3 at the bottom of the base 1, the base 1 and the flushing component 4 and water removal component 5 installed on it are moved forward as a whole until the entire set of equipment is pushed to the designated position in the cleaning area, and the equipment is in place before cleaning. After the equipment is in place, the cleaning staff starts the water pump 41 in the flushing assembly 4. At this time, the cleaning fluid stored in the water tank 43 is drawn through the water pipe 42 and transported to the hollow hose 44 fixedly connected to the water pump 41 under the negative pressure of the water pump 41, forming a stable cleaning fluid delivery channel. The cleaning fluid is then transmitted through the flexible hollow hose 44 to the five-hole nozzle 45 at the end, and sprayed out from five evenly distributed spray holes. Subsequently, the cleaning staff picks up the air conditioning copper pipe to be cleaned, aligns the five-hole nozzle 45 and the conical guide head 46 at the front end of the nozzle with the opening of the copper pipe, and slowly pushes the five-hole nozzle 45 into the copper pipe. The five-hole nozzle 45, through its multi-hole spray structure, effectively expands the coverage area of ​​the cleaning fluid, significantly improving the cleaning of the dirt on the inner wall of the copper pipe. The rinsing force of the water further removes stubborn stains. Before the cleaner pushes the five-hole nozzle 45 to the bend inside the copper tube, the tapered guide head 46 with a sloping structure will first contact the inner wall of the bend. The spring 47 will then undergo elastic deformation, which will buffer the five-hole nozzle 45 from directly hitting the inner wall of the copper tube and causing damage. The sloping structure on the surface of the tapered guide head 46 plays a guiding role when it contacts the bend, which will drive the five-hole nozzle 45 to turn flexibly and pass smoothly through the bend area, ensuring the continuity of the cleaning process. After the inner wall of the copper tube is completely rinsed, the water pump 41 is turned off to stop the supply of cleaning liquid. Then, the hollow hose 44 is slowly pulled to pull the five-hole nozzle 45 and the tapered guide head 46 out of the copper tube, completing the rinsing and cleaning steps. After rinsing and cleaning, the cleaning staff starts the air pressure pump 51 in the water removal component 5. Once the internal gas pressure of the air pressure pump 51 reaches the preset working pressure, the staff opens the exhaust valve 53, allowing high-pressure gas to enter the flexible air pipe 52, which is fixedly connected to the air outlet. Two sponges 54 and a set of double-layered soft rubber scrapers 55 are installed at the end of the air pipe 52. The cleaning staff picks up the freshly rinsed air conditioner copper pipe, aligns the end of the air pipe 52 with the water removal component with the copper pipe opening, and slowly pushes the air pipe 52 into the copper pipe. High-pressure gas is ejected from the end of the air pipe 52, first blowing out most of the residual moisture from the inner wall of the copper pipe. As the air pipe... As the double-layer soft rubber scraper 55 continues to move, it adheres tightly to the inner wall of the copper pipe, further scraping away any remaining water stains to ensure that there is no obvious water accumulation on the pipe wall surface. Finally, the two sponges 54 placed at the rear end of the double-layer soft rubber scraper 55 make full contact with the inner wall of the copper pipe. Utilizing the high water absorption of the sponges 54, they absorb the trace amounts of water that the scraper failed to remove, maximizing the water removal effect and ensuring that the inner wall of the copper pipe is dry. After the water removal of the inner wall of the copper pipe is completed, the cleaning personnel slowly pull the air hose 52 to remove the air hose 52, sponges 54, and double-layer soft rubber scraper 55 from the inside of the copper pipe. At this point, the dust removal and cleaning work of the inner wall of the air conditioning copper pipe is completely completed.

[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.
