Description

Technical Field

[0001] This application relates to the technical field of air conditioner cleaning, and in particular to a special air conditioner cleaning cart. Background Technology

[0002] In modern building environments, air conditioning systems are an indispensable component, providing people with a comfortable living environment and ensuring the safe operation of electrical equipment. However, during use, air conditioning equipment accumulates dust, dirt, and other pollutants, which not only affects the cooling and heating efficiency but may also lead to decreased air quality, increased energy consumption, and even shortened equipment lifespan. Therefore, regularly cleaning air conditioning systems is an important measure to maintain their performance and extend their service life.

[0003] Traditional air conditioner cleaning methods usually rely on manual operation. Cleaning personnel need to carry heavy cleaning equipment and water containers, frequently traveling between the water source and the air conditioning equipment. This cleaning method is not only labor-intensive and inefficient, but also makes it difficult to guarantee the thoroughness of the cleaning. Utility Model Content

[0004] In order to improve the efficiency of cleaning work and reduce labor intensity, this application provides a special cleaning cart for air conditioners.

[0005] In the first aspect, this application provides a special cleaning cart for air conditioners, which adopts the following technical solution:

[0006] An air conditioner cleaning cart includes a cart body and a push handle for easy pushing of the cart body. The cart body includes a base and wheels mounted on the underside of the base for movement. A cleaning machine, a water container for supplying water to the cleaning machine, and a battery for powering the cleaning machine are fixedly mounted on the base. A water spray pipe for spraying water is installed on the cleaning machine. A water pipe bracket for retracting the water spray pipe is also fixed on the base. The push handle is fixedly connected to one side of the base. The cart body also includes a position fixing mechanism for easy positioning of the cart body. The position fixing mechanism includes a fixing rod that is in contact with or away from the ground.

[0007] By adopting the above technical solution, when the air conditioner needs to be cleaned, the staff pushes the vehicle body to a suitable position, and the position fixing mechanism fixes the position of the vehicle body to ensure that it does not move randomly during the cleaning work. The cleaning machine is started by battery power, the water container provides water to the cleaning machine, and the cleaning water is sprayed out through the water spray pipe of the cleaning machine to achieve the effect of cleaning the inside of the air conditioner, thereby improving the efficiency of the cleaning work and reducing labor intensity.

[0008] Optionally, the push handle includes multiple uprights fixed to the upper surface of the base, each upright having an extension rod fixed to its end away from the base, the extension rod extending away from the base, and a grip rod fixed between two adjacent extension rods.

[0009] By adopting the above technical solution, the vehicle body can be easily moved by pushing it with a hand grip.

[0010] Optionally, the position fixing mechanism is located on the side of the base near the push handle. The position fixing mechanism includes a rotating bolt rotatably mounted on the base, the length direction of the rotating bolt being perpendicular to the base. A limiting component is provided on the side of the rotating bolt near the base, which allows the rotating bolt to rotate but not slide. The position fixing mechanism also includes a platform parallel to the base, a threaded hole being provided on the platform. The rotating bolt is threadedly connected to the platform through the threaded hole. The fixing rod is fixed on the side of the platform near the ground. An opening is provided on the base for the fixing rod to pass through, and the fixing rod is slidably mounted in the opening.

[0011] By adopting the above technical solution, the rotating bolt will not slide in the vertical direction under the action of the limiting component. Since the platform is threadedly connected to the rotating bolt, the platform can slide up and down along the length of the rotating bolt, thereby causing the fixed rod fixed on the platform to move up and down. When the fixed rod moves down and comes into contact with the ground, it fixes the position of the vehicle body. When the fixed rod moves away from the ground, it ensures the normal movement of the vehicle body.

[0012] Optionally, there may be multiple fixing rods, which are parallel to each other and of the same length, and a connecting rod is fixed between adjacent fixing rods to increase the contact area with the ground.

[0013] By adopting the above technical solution, the contact area between the connecting rod and the ground is further increased, thereby improving the stability of the position fixing mechanism when it is supported and fixed.

[0014] Optionally, the limiting component includes a fixing block fixed to the surface of the base, a limiting groove is formed at the center of the fixing block, the groove opening diameter is smaller than the groove bottom diameter, and a fixing ring is fixed to one side wall of the rotating bolt near the base, the fixing ring being rotatably installed in the limiting groove.

[0015] By adopting the above technical solution, since the diameter of the groove opening of the limiting groove is smaller than the diameter of the bottom of the limiting groove, the fixing ring can only rotate and cannot move up and down when it is in the limiting groove, so that the lower end of the rotating bolt will not come out of the limiting groove.

[0016] Optionally, the platform extends away from the base, and a slide rod is fixed to the end of the platform away from the rotating bolt. A limit ring is fixed to the handle, and the slide rod is slidably installed inside the limit ring.

[0017] By adopting the above technical solution, the extended platform can be used by staff to hold maintenance tools, facilitating subsequent cleaning work. The sliding rod is installed inside the limit ring to further improve the stability of the platform when sliding up and down.

[0018] Optionally, a limit block is fixed at the end of the slide rod away from the platform, and a spring is fixed between the limit block and the limit ring. The spring is sleeved on the outside of the slide rod and its two ends are respectively abutted and fixed to the limit ring and the limit ring.

[0019] By adopting the above technical solution, the spring can exert an upward force on the slide bar, thereby ensuring that the tools placed on the platform are more stable.

[0020] Optionally, a support rod is fixed to the side of the platform closest to the ground. The support rod is located on the side of the platform away from the rotating bolt, and the support rod and the fixed rod are of the same length and parallel to each other.

[0021] By adopting the above technical solution, when the fixed rod abuts against the ground, the support rod also abuts against the ground. On the one hand, it provides support for the platform, and on the other hand, it increases the contact area between the vehicle body and the ground, thereby improving the effect of fixing the vehicle in position.

[0022] In summary, this application has the following beneficial effects:

[0023] 1. When the air conditioner needs to be cleaned, the staff pushes the vehicle body to a suitable position, and the positioning mechanism fixes the position of the vehicle body to ensure that it does not move randomly during the cleaning process. The cleaning machine is started by battery power, and the water container provides water to the cleaning machine. The cleaning water is sprayed out through the water spray pipe of the cleaning machine to clean the inside of the air conditioner, thereby improving the efficiency of the cleaning work and reducing the labor intensity.

[0024] 2. The extended platform can be used by staff to hold maintenance tools, facilitating subsequent cleaning work. The sliding rod is installed inside the limit ring to further improve the stability of the platform when sliding up and down.

[0025] 3. When the fixed rod is in contact with the ground, the support rod is also in contact with the ground. On the one hand, it provides support for the platform, and on the other hand, it increases the contact area between the vehicle body and the ground, thus improving the effect of fixing the vehicle in position.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a special cleaning cart for air conditioners.

[0032] Reference Figure 1 An air conditioner cleaning cart includes a cart body 1, a push handle 2 fixed on the cart body 1, and a position fixing mechanism 3 for fixing the position of the cart body 1. The cart body 1 includes a horizontally arranged base 11, and four wheels 12 are arranged on the lower surface of the base 11. The four wheels 12 are located at the four corners of the base 11. A motor (not shown in the figure) for driving the wheels 12 to rotate and a braking system (not shown in the figure) for braking the wheels 12 when they rotate are also fixedly installed on the lower surface of the base 11. The motor drives the wheels 12 to rotate and the speed is controlled by the braking system, thereby achieving the effect of saving manpower when the cart body 1 moves a long distance.

[0033] A water container 13, a cleaning machine 14, and a water pipe rack 15 are fixed on the upper surface of the base 11. The cleaning machine 14 is located between the water container 13 and the water pipe rack 15. A water spray pipe (not shown in the figure) is installed on the cleaning machine 14. The water container 13 provides water for the cleaning machine 14 to spray water. The water spray pipe can be stored on the water pipe rack 15. When water spraying is required, the water spray pipe is taken out from the water pipe rack 15 for cleaning. A battery 16 that powers the cleaning machine 14 is also fixed on the lower surface of the base 11. When there is no external power supply, the battery 16 can power the cleaning machine 14. The position fixing mechanism 3 is located on the side near the push handle 2. When it is necessary to fix the position of the vehicle body 1, the position fixing mechanism 3 fixes the position of the vehicle body 1. When it is necessary to move the vehicle body 1, the position fixing mechanism 3 no longer fixes the position, ensuring the normal movement of the vehicle body 1.

[0034] Reference Figure 2 The push handle 2 includes two uprights 21 that are vertically fixed to one side of the base 11. The two uprights 21 are parallel to each other and perpendicular to the base 11. An extension rod 22 is fixed to the upper end of each upright 21. The extension rod 22 extends and is fixed to the side away from the base 11. A handle 23 is fixed to the end of the extension rod 22 away from the upright 21. The handle 23 is fixed between the two extension rods 22 and is parallel to the base 11. The handle 23 pushes the vehicle body 1 to move, thereby reducing the labor intensity of the cleaning work.

[0035] A cable box 17 is also fixed on the pole 21. The cable box 17 contains a cable that is electrically connected to the cleaning machine 14. The cleaning machine 14 can be powered by connecting to an external power source through the cable.

[0036] Reference Figure 2 and Figure 3 The position fixing mechanism 3 includes a platform 31 horizontally arranged between two uprights 21, a rotating bolt 32 for moving the platform 31 up and down, and a limiting component 33 for limiting the rotating bolt 32. Two fixing rods 34 are fixed at intervals on the lower surface of the platform 31. An opening 111 is provided on the base 11 for the fixing rods 34 to pass through. The opening 111 limits the up and down sliding of the fixing rods 34. A connecting rod 35 is fixed between the two fixing rods 34. The connecting rod 35 is located below the base 11. When the fixing rods 34 abut against the ground, the connecting rod 35 further increases the contact area with the ground, thereby improving the position fixing effect.

[0037] A threaded hole 311 is vertically and through the platform 31. The axis of the threaded hole 311 is perpendicular to the base 11. The rotating bolt 32 is threaded into the threaded hole 311, and the lower end of the rotating bolt 32 is restricted to the base 11 by the limiting component 33, so that the rotating bolt 32 can only rotate on the base 11 and cannot slide up and down.

[0038] The limiting component 33 includes a fixing block 331 fixed on the base 11. A limiting groove 332 is formed at the center of the fixing block 331. The width of the opening of the limiting groove 332 is smaller than the width of the bottom of the limiting groove 332. The axis of the limiting groove 332 is on the same straight line as the axis of the rotating bolt 32. A fixing ring 333 is coaxially fixed to the lower end of the rotating bolt 32. The fixing ring 333 is located in the limiting groove 332 and can rotate within the limiting groove 332. The rotating bolt 32 extends out from the opening of the limiting groove 332, so that the lower end of the rotating bolt 32 cannot be disengaged from the limiting groove 332. When the rotating bolt 32 is rotated in the forward or reverse direction, the platform 31 slides up and down along the length direction of the rotating bolt 32 under the action of the threaded hole 311, thereby realizing the up and down sliding of the fixing rod 34. When the fixing rod 34 abuts against the ground, the position of the vehicle body 1 is fixed, ensuring the stable operation of the cleaning work.

[0039] Platform 31 extends horizontally away from base 11, allowing it to hold other tools used by staff and facilitating cleaning work. A support rod 312 is also vertically fixed to the side of platform 31 away from the fixed rod 34. The support rod 312 extends towards the ground and is the same length as the fixed rod 34 and parallel to each other, further improving stability when the position is fixed.

[0040] Two sliding rods 313 are vertically fixed to the upper surface of the platform 31. The sliding rods 313 are located on the side of the platform 31 away from the base 11. Two limiting rings 231 are fixed on the handle 23. The axis of the limiting rings 231 is perpendicular to the platform 31. The limiting rings 231 and the sliding rods 313 are opposite each other, and the sliding rods 313 pass through the limiting rings 231. The limiting rings 231 limit the sliding of the sliding rods 313. A limiting block 315 is fixed to the upper end of the sliding rod 313. The diameter of the limiting block 315 is larger than the diameter of the sliding rod 313. A spring 314 is also sleeved on the sliding rod 313. The spring 314 is fixed between the limiting block 315 and the limiting rings 231. When the platform 31 slides downward, the spring 314 is compressed. When the platform 31 slides upward, the spring 314 returns to its initial state and gives the side of the platform 31 away from the rotating bolt 32 an upward lifting force, thereby improving the stability of the platform 31.

[0041] The implementation principle of the special air conditioner cleaning cart in this application embodiment is as follows:

[0042] When the air conditioner needs cleaning, the vehicle body 1 is moved to a suitable position by pushing the handle 2. The position fixing mechanism 3 fixes the position of the vehicle body 1 to ensure the cleaning work can proceed. The water spray pipe of the cleaning machine 14 sprays water quickly to clean and improve cleaning efficiency. By rotating the rotating bolt 32, the platform 31 slides downward and the fixing rod 34 comes into contact with the ground, thus fixing the position. The sliding rod 313 and the limiting ring 231 further improve the stability of the platform 31 sliding up and down. When the rotating bolt 32 is rotated in the opposite direction, the platform 31 slides upward, thereby allowing the fixing rod 34 to slide upward away from the ground, so that the vehicle body 1 can resume movement.

[0043] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
