It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0028] like Figures 1 to 3As shown, the present application provides a movable air conditioner, and an embodiment of the movable air conditioner includes: an air conditioner body 1 and a moving mechanism 3, wherein the moving mechanism 3 includes a base 301, a forward and reverse motor 307, two threaded rods 304, and a plurality of universal wheels 316. The base 301 is arranged at the bottom of the air conditioner body 1, and two slots 302 are provided on both sides of the bottom of the base 301, and each threaded rod 304 is rotatably arranged at the top of each slot 302, and the forward and reverse motor 307 is arranged inside the base 301 and between the two slots 302, and the plurality of universal wheels 316 are connected to the two threaded rods 304 in a transmission manner. The forward and reverse motor 307 drives the two threaded rods 304 to rotate at the same time through a belt transmission structure, so that the plurality of universal wheels 316 move along the up and down direction of the air conditioner body 1, so that the plurality of universal wheels 316 have a supporting position protruding from the bottom surface of the base 301 and a storage position located in the two slots 302.

[0029] Applying the technical solution of this embodiment, the movable air conditioner includes: an air conditioner body 1 and a moving mechanism 3, wherein the moving mechanism 3 includes a base 301, a forward and reverse motor 307, two threaded rods 304 and a plurality of universal wheels 316. When the air conditioner needs to be moved, the threaded rod 304 is driven to rotate by starting the forward and reverse motor 307, so that the plurality of universal wheels 316 move downward along the up and down direction of the air conditioner body 1, so that the plurality of universal wheels 316 are in a supporting position, and at this time, the plurality of universal wheels 316 are in contact with the ground, and the plurality of universal wheels 316 can roll on the ground, which is convenient for the staff to move the air conditioner, saving time and effort while reducing the probability of collision and damage during movement. Therefore, the technical solution of this embodiment effectively solves the problem of inconvenience in the movement of the computer room air conditioner in the related art.

[0030] A control panel 101 is fixedly mounted on the front end of the air conditioner body 1 of this embodiment, an exhaust hole 102 is provided on the front end of the air conditioner body 1 and above the control panel 101, ventilation nets 103 are fixedly mounted on both sides of the air conditioner body 1, and a heat dissipation fan 104 is mounted on the ventilation net 103 and inside the air conditioner body 1. The air conditioner body 1 has a compressor, an evaporator, and a condenser.

[0031] like Figures 1 to 3As shown, the mobile mechanism 3 also includes: two lifting seats 311. Each lifting seat 311 is arranged inside the slot 302, and two threaded rods 304 are connected to the top of the two lifting seats 311 in a one-to-one correspondence and rotatably, and a plurality of universal wheels 316 are connected to the bottom of the two lifting seats 311. When the forward and reverse motor 307 is started, the threaded rod 304 is rotated through the belt transmission structure, driving the lifting seat 311 to move up and down, so that the universal wheel 316 switches between the supporting position and the storage position, and finally realizes the flexible movement and stable positioning of the air conditioner body 1. Through the up and down movement of the lifting seat 311, the telescopic movement of the universal wheel 316 is realized, making it more convenient for the air conditioner to switch between the mobile and fixed states, and is suitable for places such as data centers and laboratories where the position of the air conditioner needs to be frequently adjusted. In a laboratory environment, this design is particularly useful. Experimental equipment often needs to be rearranged according to experimental requirements. The fast switching capability of the movable air conditioner greatly saves the adjustment time of the experimenter and improves the experimental efficiency. At the same time, it also avoids the damage of the universal wheel to the experimental table when it is in a fixed position.

[0032] like Figures 1 to 3 As shown, each lifting seat 311 is provided with an internal threaded hole 312, and each threaded rod 304 is connected to each internal threaded hole 312. When the threaded rod 304 rotates, according to the principle of threaded movement, the lifting seat 311 threadedly connected to the threaded rod 304 will move along the axis direction of the threaded rod 304. In this way, when the threaded rod 304 rotates forward or reversely, the up and down movement of the lifting seat 311 can be accurately controlled, so as to realize the protrusion and storage of the universal wheel, and ensure the stability and safety of the movement. This threaded connection method makes the movement of the lifting seat 311 more stable, avoids the position deviation of the universal wheel 316 caused by uneven ground or gravity during the movement, and enhances the stability of the air conditioner when moving. In actual operation, this enhancement of stability is very critical to avoid accidental sliding of the air conditioner during movement, especially in an environment with a slight tilt or uneven ground, which can effectively prevent the air conditioner from tipping over and ensure the safety of personnel and the air conditioner.

[0033] like Figures 1 to 3As shown, both sides of the lifting seat 311 are fixedly installed with limit rods 313, and a slider 314 is fixedly installed at one end of the limit rod 313 away from the lifting seat 311. Slide grooves 315 are provided on both sides of the slot 302, and the slide grooves 315 extend along the up and down directions of the air conditioner body 1. Each slider 314 is located in a slide groove 315, and each slider 314 can slide in the slide groove 315. When the lifting seat 311 is raised or lowered, the limit rod 313 and the slider 314 slide in the slide groove 315. This mechanical structure limits the lateral displacement of the lifting seat 311 and ensures the vertical movement path of the universal wheel, thereby providing a stable support during the movement of the air conditioner body 1 and preventing the risk of the air conditioner sliding or tipping over. The setting of the limit rod 313 and the slider 314 further improves the stability of the movement of the lifting seat 311, ensures the linear movement of the universal wheel 316 during the extension and retraction process, avoids unnecessary lateral shaking, and is suitable for environments requiring high-precision positioning. For example, in a precision electronic equipment factory where the position of the air conditioner needs to be precisely controlled, this high-precision positioning capability can ensure that the air conditioner is accurately aimed at the equipment that needs cooling, avoiding uneven temperature control due to air conditioner position deviation and protecting the normal operation of the equipment.

[0034] like Figures 1 to 3 As shown, a driving groove 306 for installing a forward and reverse motor 307 is provided inside the base 301. The belt transmission structure includes a rotating rod 308, two driving wheels 309, two driven wheels 305 and two driving belts 310. The rotating rod 308 is fixedly mounted on the output end of the forward and reverse motor 307, the two driving wheels 309 are fixedly connected to the rotating rod 308 at intervals, the two driven wheels 305 are respectively mounted on the two threaded rods 304, and each driving belt 310 is sleeved on the outside of a driving wheel 309 and a driven wheel 305. The forward and reverse motor 307 drives the driving wheel 309 through the rotating rod 308, and transmits power to the driven wheel 305 through the driving belt 310, thereby driving the threaded rod 304 to rotate. This design reduces the friction and wear that may be generated by directly driving the threaded rod, ensuring the efficiency of power transmission and the long-term stable operation of the system. The use of the belt transmission structure reduces the energy loss in the transmission process, improves the use efficiency of the forward and reverse motor 307, and is suitable for scenes with high requirements for energy utilization efficiency. In scenarios with strict energy management, such as energy-saving buildings or green data centers, this high-efficiency belt drive structure can reduce energy consumption and lower operating costs, while also reducing maintenance issues caused by motor overheating and extending the service life of the air conditioner.

[0035] like Figures 1 to 3As shown, two driving wheels 309 are fixedly connected to the rotating rod 308 at equal intervals. The two driving wheels 309 are fixed at equal intervals so that the driving force they receive is uniform, and the two driven wheels 305 are driven to rotate synchronously through the driving belt 310, thereby ensuring the synchronous lifting and lowering of the two threaded rods 304, and avoiding the tilting or deviation of the air conditioner body 1 during the movement. In actual use, this uniform movement characteristic is crucial to maintaining the balance of the air conditioner, especially when passing through narrow passages or turning, avoiding the shaking or jamming of the air conditioner due to uneven force on the universal wheel on one side, and ensuring the smooth movement of the air conditioner.

[0036] like Figures 1 to 3 As shown, the mobile mechanism 3 also includes: two fixed boxes 303, each of which is arranged at the top of the inner part of the slot 302, and two threaded rods 304 are rotatably mounted on the two fixed boxes 303 in a one-to-one correspondence. The fixed box 303 is at the top of the inner part of the slot 302, on the one hand, fixes the threaded rod 304, and on the other hand, provides a rotating guide bearing for the threaded rod, ensuring that the threaded rod can rotate smoothly when bearing the weight of the lifting seat 311 and the universal wheel 316, avoiding wear or failure caused by unstable support. The setting of the fixed box 303 provides stable support for the threaded rod 304, ensuring its stability during the rotation process, and is suitable for air-conditioning equipment that needs to be frequently moved, such as exhibition halls, temporary office places, etc. In these places, the movement frequency of the air conditioner is much higher than that in conventional environments. The fixed box provides stable support for the threaded rod, preventing the structure from loosening or damage due to frequent movement, and ensuring the stable operation of the air conditioner in any usage scenario.

[0037] like Figure 1 , Figure 4 and Figure 5 As shown, the mobile air conditioner also includes a drainage device, which includes a first drainage pipe 105 and a drainage recovery mechanism 2, and the drainage recovery mechanism 2 is connected to the rear end of the air conditioner body 1 through the first drainage pipe 105. The condensed water generated when the air conditioner is running is discharged from the air conditioner body 1 to the drainage recovery mechanism 2 through the first drainage pipe 105. This design enables the condensed water to be collected and processed in a centralized manner instead of being directly discharged to the ground, thereby reducing the waste of water resources. At the same time, through recycling and reuse, such as for cooling system water replenishment or machine room cleaning, the utilization efficiency of water resources is improved. This design enables the air conditioner to automatically process the condensed water during movement, avoiding the pollution of the ground by the dripping of the condensed water, and improving the convenience and environmental friendliness of the use of the air conditioner. In places with strict requirements on the environment, such as data centers and hospitals, the automatic recovery and treatment of condensed water avoids pollution to the ground, reduces cleaning work, and avoids electrical safety problems caused by the overflow of condensed water, thereby improving the safety and cleanliness of the overall environment.

[0038] like Figure 1 , Figure 4 and Figure 5 As shown, the drainage recovery mechanism 2 includes a recovery box 201, a water storage tank 203 and a one-way valve 205. The recovery box 201 is arranged at the end of the first drainage pipe 105 away from the air conditioner body 1, and the water storage tank 203 is connected to the right bottom end of the recovery box 201 through the second drainage pipe 202. A third drainage pipe 204 is fixedly installed at the right bottom end of the water storage tank 203, and the one-way valve 205 is installed on the third drainage pipe 204. The setting of the one-way valve 205 prevents the water in the water storage tank 203 from flowing back, ensuring the smooth progress of the drainage process, and is suitable for air conditioning equipment that needs to run for a long time and cannot be interrupted, such as server rooms, precision instrument rooms, etc. In the server room, this drainage recovery system can ensure that the condensed water of the air conditioner in long-term operation is handled in time, avoiding damage and failure of the air conditioner caused by the accumulation of condensed water, while reducing the server interruption time caused by maintenance, and improving the continuity and quality of service.

[0039] like Figure 1 , Figure 4 and Figure 5 As shown, the recovery box 201 is provided with a first coil and a second coil. The recovery box 201 is connected to the internal drainage pipe of the air conditioner body 1 through the first coil and the first drainage pipe 105, and the recovery box 201 is connected to the inside of the water storage tank 203 through the second coil and the second drainage pipe 202. Condensed water first flows into the recovery box 201, undergoes preliminary cooling and purification through the first coil, and then enters the water storage tank 203 through the second drainage pipe 202 and the second coil for storage. The one-way valve 205 ensures the singleness of the water flow direction, prevents the water flow from backtracking, and ensures the continuity and safety of the condensed water recovery process. When the water source in the water storage tank needs to be used, the release can be controlled by the third drainage pipe 204 and the one-way valve 205, achieving the secondary utilization of water resources and environmental protection goals. The recovery efficiency of condensed water is improved, and it is suitable for scenes with high requirements for air conditioning operation efficiency, such as large data centers, hospital operating rooms, etc.

[0040] The specific operation methods of this application are as follows:

[0041] First, when the staff needs to move the air conditioner, the forward and reverse motor 307 is started to drive the rotating rod 308 and the driving wheel 309 to rotate, so that the driving wheel 309 drives the driving belt 310 to rotate, and the driven wheel 305 is driven to rotate under the action of the driving belt 310, and the driven wheel 305 drives the threaded rod 304 to rotate. At the same time, the limiting rod 313, the slider 314 and the slide groove 315 play a limiting role, so that the lifting seat 311 is displaced downward under the action of the internal threaded hole 312 and the threaded rod 304, so that the universal wheel 316 is in contact with the ground, which is convenient for the staff to move. When draining water, the water source is discharged into the recovery box 201 through the first drain pipe 105 and the first coil for treatment, and then discharged into the water storage tank 203 through the second drain pipe 202 and the second coil for storage. When the water source needs to be used for a second time, the one-way valve 205 is opened to allow the water source to be discharged through the third drain pipe 204 for secondary use.

[0042] Compared with the prior art, the beneficial effects of this application are:

[0043] 1. The mobile mechanism set up in the present application can start the forward and reverse motors to drive the rotating rod and the driving wheel to rotate when the air conditioner needs to be moved, so that the driving wheel drives the driving belt to rotate, and the driven wheel drives the threaded rod to rotate under the action of the driving belt, so that the lifting seat moves downward under the action of the internal threaded hole and the threaded rod, and at the same time, the limit rod, the slider and the slide groove play a limiting role, so that the universal wheel contacts the ground, which is convenient for the staff to move, saves time and effort, and reduces the probability of bumps and damages during movement.

[0044] 2. The present application sets up a drainage recovery mechanism. When draining water, the water source is discharged into the recovery box through the first drainage pipe and the first coil for treatment, and then discharged into the water storage tank through the second drainage pipe and the second coil for storage. When the water source needs to be used for a second time, the one-way valve is opened to allow the water source to be discharged through the drainage pipe for secondary use, thereby achieving secondary utilization of the water source, saving water while preventing the ground from getting wet.

[0045] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0046] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0047] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
