Description

Technical Field

[0001] This invention relates to the field of small household appliance technology, and in particular to a multifunctional vertical portable air conditioner. Background Technology

[0002] As people's living standards improve, portable floor-standing air conditioners are widely used in various scenarios such as rented apartments, temporary offices, and small shops due to their flexibility and lack of fixed installation requirements. However, there are still many technical defects in the floor-standing portable air conditioners currently on the market that urgently need to be addressed.

[0003] Firstly, the support bases of existing vertical portable air conditioners are mostly integrated fixed structures, which can only realize the simple support and movement functions of the equipment, but cannot realize the horizontal rotation adjustment of the air conditioner itself. Due to the limited air delivery range of portable air conditioners, the fixed-angle air delivery mode makes it difficult to achieve a uniform temperature in the indoor space, and is prone to local uneven heating and cooling problems. Especially in larger spaces, it cannot meet the comfort needs of multiple areas, thus limiting the applicable scenarios and usage flexibility of the equipment.

[0004] Secondly, the edges and corners of a vertical portable air conditioner are mostly exposed. During movement, handling, or daily use, the edges and corners are easily worn and deformed due to collisions and friction. This can even damage the internal cooling pipes, circuit components, and other core parts, affecting not only the appearance of the equipment but also shortening its lifespan and increasing the user's maintenance costs.

[0005] In addition, the height of existing vertical portable air conditioners is fixed and cannot be flexibly adjusted according to user needs. When users need to cool / heat high spaces, the fixed height design will cause inconvenience, resulting in poor air supply effect at high places and limited user experience. Summary of the Invention

[0006] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a vertical portable air conditioner that can protect the corners of the air conditioner body, achieve height adjustment, and has a compact structure and convenient operation.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A multifunctional vertical portable air conditioner includes a support base and an air conditioner body disposed on the support base. The support base includes a fixed seat and a rotating seat rotatably disposed on the fixed seat. Four upwardly extending vertical protective sleeves are provided at the upper end of the rotating seat. The four vertical protective sleeves are respectively fitted onto the four vertical corners of the air conditioner body, and the air conditioner body can move up and down on the four vertical protective sleeves. A lifting mechanism that can drive the air conditioner body to move up and down is also provided on the rotating seat.

[0009] In some embodiments, the lifting mechanism includes lead screws disposed within each of the vertical protective sleeves. Each lead screw is vertically arranged and threaded with a lead screw nut sleeve. The lead screw nut sleeve is fixedly connected to the air conditioner body. A power mechanism capable of driving all the lead screw nut sleeves to rotate synchronously is disposed on the rotating seat.

[0010] In some embodiments, the power mechanism includes a first motor disposed within the rotating base, a main synchronous pulley disposed on the output shaft of the first motor, a secondary synchronous pulley disposed on each of the lead screws, and a synchronous belt connected and sleeved between the main synchronous pulley and all the secondary synchronous pulleys.

[0011] In some embodiments, a plurality of tensioning pulleys for pressing the timing belt are also provided inside the rotating seat.

[0012] In some embodiments, receiving grooves for accommodating the lead screw are provided on each of the four vertical corners of the air conditioner body.

[0013] In some embodiments, an extension limiting plate extending into the receiving groove is provided at the upper end of the vertical protective sleeve, a first guide block is provided on the extension limiting plate, and a first vertical slide groove for the first guide block to slide is provided on the side wall of the receiving groove.

[0014] In some embodiments, a second guide block is provided on the lead screw nut sleeve, and a second vertical groove is provided on the inner sidewall of the vertical protective sleeve for the second guide block to slide.

[0015] In some embodiments, a rotating column is provided at the lower end of the rotating base, and a circular groove is provided at the upper end of the fixed base for the rotating column to be rotatably mounted, and the first motor is located inside the rotating column.

[0016] In some embodiments, a second motor is further provided inside the rotating column, a drive gear is provided on the output shaft of the second motor, and an internal gear ring is fixedly provided in the circular groove, the drive gear meshing with the internal gear ring.

[0017] In some embodiments, a plurality of movable wheels are evenly distributed around the lower end of the fixed base along the circumference, and adjustable support feet are provided at the four corners of the fixed base.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The support base adopts a rotating joint structure of a fixed base and a rotating base. The rotating base can rotate flexibly relative to the fixed base, thereby driving the air conditioner body on it to rotate synchronously, breaking the limitation of the fixed angle air supply of existing portable air conditioners. Users can flexibly adjust the air supply direction of the air conditioner body according to their needs to achieve 360° all-round air supply, effectively improving the problem of uneven heating and cooling in indoor spaces. It is especially suitable for use in large spaces, significantly improving the applicable scenarios and user comfort of the equipment, and solving the pain point of limited air supply range of existing equipment.

[0020] 2. The four vertical protective sleeves on the upper part of the rotating base are respectively fitted onto the four vertical corners of the air conditioner body, which can provide all-round protection for the corners of the air conditioner body, avoiding wear and deformation of the corners due to collision and friction during the movement, handling or daily use of the equipment, and ensuring the integrity of the equipment's appearance and the safety of use.

[0021] 3. The lifting mechanism on the rotating base can drive the air conditioner body to move up and down on the four vertical protective covers. Users can flexibly adjust the height of the air conditioner body according to actual usage needs, adapt to the temperature sensing needs of spaces of different heights, and improve the user experience.

[0022] 4. The vertical protective sleeve and lifting mechanism are integrated into the rotating base, which not only provides corner protection but also guides the air conditioner body to move up and down, preventing tilting or jamming during the lifting process and improving the stability of the lifting process. At the same time, the overall structure is compact, does not occupy extra space, and does not affect the portability of the equipment. The cooperation between the rotating base and the fixed base further improves the stability of the equipment when placed and reduces the risk of tipping over. Compared with the existing separate protection and lifting structures, it has a higher degree of integration and stronger practicality. Attached Figure Description

[0031] The following detailed description provides various embodiments or examples for carrying out the present invention. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of the invention and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0032] like Figures 1-8 The multifunctional vertical portable air conditioner shown includes a support base 1 and an air conditioner body 2 disposed on the support base 1. The support base 1 includes a fixed seat 3 and a rotating seat 4 rotatably disposed on the fixed seat 3. Four upwardly extending vertical protective sleeves 5 are provided at the upper end of the rotating seat 4. The four vertical protective sleeves 5 are respectively fitted onto the four vertical corners of the air conditioner body 2, and the air conditioner body 2 can move up and down on the four vertical protective sleeves 5. A lifting mechanism that can drive the air conditioner body 2 to move up and down is also provided on the rotating seat 4.

[0033] In the above structure, the support base 1 serves as the foundation for the entire air conditioning unit, providing stable support for the air conditioning unit 2 mounted on it. This ensures the overall stability of the unit during use and prevents it from tipping over due to a shift in the center of gravity. It is the fundamental support component for the normal operation of the air conditioning unit 2. The support base 1 consists of a fixed base 3 and a rotating base 4, with the rotating base 4 rotatably mounted on the fixed base 3. This mating structure allows the rotating base 4 to rotate flexibly horizontally relative to the fixed base 3, thereby causing the air conditioning unit 2 mounted on the rotating base 4 to rotate horizontally synchronously. This enables flexible adjustment of the airflow direction of the air conditioning unit 2, breaking the limitations of fixed-angle airflow.

[0034] The upper end of the rotating base 4 is provided with four upward-extending vertical protective sleeves 5. The four vertical protective sleeves 5 are respectively fitted onto the four vertical corners of the air conditioner body 2. On the one hand, they provide all-round protection for the four vertical corners of the air conditioner body 2, preventing damage to the corners of the air conditioner body 2 due to collisions or friction during movement, handling or use. On the other hand, the vertical protective sleeves 5 provide vertical guidance for the air conditioner body 2, limiting the movement trajectory of the air conditioner body 2 and ensuring that the air conditioner body 2 can only move up and down along the extension direction of the vertical protective sleeves 5, avoiding tilting, deviation or jamming when the air conditioner body 2 moves up and down.

[0035] The rotating base 4 is also equipped with a lifting mechanism, which serves as a power output component. This mechanism generates vertical driving force to drive the air conditioner body 2 to move up and down along the guide direction of the four vertical protective sleeves 5, thus enabling flexible adjustment of the height of the air conditioner body 2. When it is necessary to adjust the air conditioner's air supply height, the lifting mechanism drives the air conditioner body 2 to rise or fall to a suitable position, meeting the height requirements of different usage scenarios and improving the ease of use of the equipment.

[0036] During the overall operation, the fixed base 3 remains stationary, providing stable rotational support for the rotating base 4; the rotating base 4 can drive the air conditioner body 2 to rotate horizontally and adjust the air supply direction; the vertical protective sleeve 5 not only provides corner protection but also works with the lifting mechanism to complete the vertical guidance of the air conditioner body 2; the lifting mechanism provides lifting power to drive the air conditioner body 2 to move up and down. All components work together to ensure that the equipment has the functions of stable support, flexible rotation, corner protection, and height adjustment, ensuring stable and convenient operation of the equipment.

[0037] See Figures 5-8 As shown, the lifting mechanism includes a lead screw 21 disposed in each of the vertical protective sleeves 5. Each lead screw 21 is vertically arranged and threaded with a lead screw nut sleeve 22. The lead screw nut sleeve 22 is fixedly connected to the air conditioner body 2. A power mechanism capable of driving all the lead screw nut sleeves 22 to rotate synchronously is provided on the rotating seat 4.

[0038] The power mechanism includes a first motor 31 located inside the rotating seat 4, a main synchronous pulley 32 on the output shaft of the first motor 31, a secondary synchronous pulley 33 on each of the lead screws 21, a synchronous belt 34 connected between the main synchronous pulley 32 and all the secondary synchronous pulleys 33, and a plurality of tensioning pulleys 41 for pressing the synchronous belt 34 are also provided inside the rotating seat 4.

[0039] The lead screw 21 is installed inside each vertical protective sleeve 5 and is arranged vertically. Each lead screw 21 is threaded with a lead screw nut sleeve 22, which is fixedly connected to the air conditioner body 2. When the lead screw 21 rotates, the threaded connection between the lead screw 21 and the lead screw nut sleeve 22 can be used to convert the rotational motion of the lead screw 21 into the vertical linear motion of the lead screw nut sleeve 22. This, in turn, drives the air conditioner body 2, which is fixedly connected to the lead screw nut sleeve 22, to move up and down synchronously along the guide direction of the vertical protective sleeve 5, thereby realizing the height adjustment of the air conditioner body 2.

[0040] The power mechanism is used to drive all the lead screws 21 to rotate synchronously, ensuring that the air conditioner body 2 is subjected to uniform force and is stable and tilt-free during the lifting and lowering process. It consists of a first motor 31, a main synchronous pulley 32, a secondary synchronous pulley 33, and a synchronous belt 34. The first motor 31 is located inside the rotating base 4 and serves as the power output source. When the first motor 31 starts, its output shaft drives the main synchronous pulley 32 located on it to rotate synchronously. Each lead screw 21 is equipped with a secondary synchronous pulley 33. A synchronous belt 34 is sleeved between the main synchronous pulley 32 and all the secondary synchronous pulleys 33. When the main synchronous pulley 32 rotates, it drives all the secondary synchronous pulleys 33 to rotate synchronously through the transmission action of the synchronous belt 34, thereby driving each lead screw 21 connected to the secondary synchronous pulleys 33 to rotate synchronously. This ensures that the rotation speed and direction of all lead screws 21 are completely consistent, avoiding the air conditioner body 2 from jamming or tilting due to differences in the speed of a single lead screw 21.

[0041] The rotating base 4 also contains several tension pulleys 41. The core function of the tension pulleys 41 is to tighten the synchronous belt 34, preventing it from slipping due to slack during transmission, ensuring the stability and accuracy of power transmission, and reducing wear on the synchronous belt 34, thus extending the service life of the power mechanism. The tension pulleys 41 work in conjunction with the main synchronous pulley 32, the auxiliary synchronous pulley 33, and the synchronous belt 34 to ensure smooth power transmission, thereby ensuring that the lifting mechanism can stably drive the air conditioner body 2 to complete the up and down lifting movements.

[0042] The overall workflow is as follows: The first motor 31 is started, and the output shaft of the first motor 31 drives the main synchronous pulley 32 to rotate. The main synchronous pulley 32 drives all the auxiliary synchronous pulleys 33 to rotate synchronously through the synchronous belt 34. The auxiliary synchronous pulleys 33 drive the corresponding lead screw 21 to rotate synchronously. When the lead screw 21 rotates, the lead screw nut sleeve 22, which is threaded with the lead screw 21, moves vertically along the lead screw 21, driving the air conditioner body 2 to move up and down along the vertical protective sleeve 5 to achieve height adjustment. During this process, the tensioning wheel 41 always presses the synchronous belt 34 to ensure stable power transmission. All components work together to achieve smooth and precise lifting control of the air conditioner body 2.

[0043] Furthermore, in order to achieve a reasonable fit between the lead screw 21 and the air conditioner body 2, and to avoid the lead screw 21 being exposed and affecting the compactness of the equipment structure and the safety of use, receiving grooves 51 are provided on the four vertical corners of the air conditioner body 2. The receiving grooves 51 are used to accommodate the lead screw 21, so that the lead screw 21 can be embedded inside the corners of the air conditioner body 2. This not only saves the overall space of the equipment, but also provides a certain degree of protection for the lead screw 21, preventing the lead screw 21 from being affected by external collisions, dust adhesion, etc., and ensuring the normal transmission performance of the lead screw 21.

[0044] To further improve the stability of the air conditioner body 2 during the vertical lifting process and prevent the air conditioner body 2 from deviating, shaking or detaching from the vertical protective sleeve 5, an extension limiting plate 61 is provided at the upper end of the vertical protective sleeve 5. The extension limiting plate 61 extends into the receiving groove 51, forming a deep fit between the vertical protective sleeve 5 and the air conditioner body 2, which plays a preliminary limiting role on the lifting trajectory of the air conditioner body 2 and prevents the air conditioner body 2 from deviating horizontally during the lifting process.

[0045] A first guide block 62 is provided on the extension limiting plate 61. Correspondingly, a first vertical slide groove 63 is provided on the side wall of the receiving groove 51. The first guide block 62 can slide vertically within the first vertical slide groove 63. This mating structure forms a first layer of guiding and limiting, further restricting the movement trajectory of the air conditioner body 2, ensuring that the air conditioner body 2 can only rise and fall smoothly in the vertical direction, avoiding tilting or jamming. At the same time, it can disperse the force on the air conditioner body 2 during the rising and falling process, reduce the friction between the vertical protective sleeve 5 and the air conditioner body 2, and improve the smoothness of the rising and falling process.

[0046] A second guide block 71 is provided on the lead screw nut sleeve 22, and a second vertical groove 72 is provided on the inner wall of the vertical protective sleeve 5 for the second guide block 71 to slide. The second guide block 71 and the second vertical groove 72 slide in cooperation to form a second guide limit. Since the lead screw nut sleeve 22 is fixedly connected to the air conditioner body 2, the second guide block 71 moves vertically synchronously with the lead screw nut sleeve 22, which can further constrain the movement direction of the lead screw nut sleeve 22, prevent the lead screw nut sleeve 22 from rotating synchronously with the lead screw 21, and ensure that the rotational motion of the lead screw 21 can be stably converted into the vertical linear motion of the lead screw nut sleeve 22, thereby driving the air conditioner body 2 to rise and fall smoothly.

[0047] Furthermore, when the air conditioner body 2 is raised or lowered, the receiving groove 51 provides a space for the lead screw 21, ensuring structural adaptability; the extended limiting plate 61 is embedded in the receiving groove 51 to achieve initial limiting; the first guide block 62 slides along the first vertical slide groove 63 and the second guide block 71 slides along the second vertical slide groove 72. The dual guide limiting structure works together to limit the movement trajectory of the air conditioner body 2 and the lead screw nut sleeve 22, avoiding deviation, rotation or jamming; at the same time, in conjunction with the power transmission of the original lifting mechanism, the air conditioner body 2 can smoothly and accurately complete the up and down lifting action along the guide direction of the vertical protective sleeve 5 and the lead screw 21, further improving the stability and reliability of the equipment lifting process.

[0048] See Figure 6 , Figure 8As shown, a rotating column 81 is provided at the lower end of the rotating base 4, and a circular groove 82 is provided at the upper end of the fixed base 3 for the rotating column 81 to be rotatably mounted. The first motor 31 is located inside the rotating column 81, and a second motor 91 is also provided inside the rotating column 81. A drive gear 92 is provided on the output shaft of the second motor 91, and an internal gear ring 93 is fixedly provided in the circular groove 82. The drive gear 92 meshes with the internal gear ring 93.

[0049] To enable flexible and stable rotation of the rotating base 4 relative to the fixed base 3, a rotating column 81 is provided at the lower end of the rotating base 4. Correspondingly, a circular groove 82 is provided at the upper end of the fixed base 3. The rotating column 81 is rotatably installed in the circular groove 82, forming a rotational mating structure between the rotating base 4 and the fixed base 3. The circular groove 82 provides a stable installation and rotation space for the rotating column 81, limiting the rotating column 81 to horizontal rotation only along the center of the circular groove 82. This drives the rotating base 4, which is fixedly connected to the rotating column 81, to rotate synchronously, providing a structural basis for adjusting the horizontal airflow direction of the air conditioner body 2, while ensuring the smoothness of the rotation process and preventing the rotating base 4 from shifting or shaking.

[0050] To make reasonable use of space and optimize the overall structural layout of the equipment, the first motor 31 is located inside the rotating column 81. This not only saves the installation space inside the rotating seat 4, but also provides a certain degree of protection for the first motor 31. At the same time, it facilitates the power connection between the first motor 31 and the lifting mechanism assembly on the rotating seat 4, ensuring the normal operation of the lifting mechanism and realizing the integrated layout of the power assembly and the rotating assembly.

[0051] To provide stable power for the rotation of the rotating seat 4 and to achieve controllable rotation of the rotating seat 4 and the air conditioner body 2, a second motor 91 is also provided in the rotating column 81. The second motor 91 serves as the rotation power output source. A drive gear 92 is provided on the output shaft of the second motor 91. Correspondingly, an internal gear ring 93 is fixedly provided in the circular groove 82, and the drive gear 92 meshes with the internal gear ring 93 to form a gear transmission structure, thereby achieving stable power transmission.

[0052] Its power transmission and rotation working logic is as follows: When it is necessary to adjust the air supply direction of the air conditioner body 2, the second motor 91 is started, and the output shaft of the second motor 91 drives the drive gear 92 to rotate synchronously; since the internal gear ring 93 is fixedly set in the circular groove 82, and the drive gear 92 meshes with the internal gear ring 93, the drive gear 92 will roll along the tooth surface of the internal gear ring 93 when rotating, thereby driving the second motor 91 and the rotating column 81 connected to the drive gear 92 to rotate synchronously; the rotating column 81 drives the rotating seat 4 at its upper end to rotate, and the rotating seat 4 further drives the air conditioner body 2, the vertical protective sleeve 5, the lifting mechanism and other components on it to rotate synchronously horizontally, ultimately realizing the flexible adjustment of the air supply direction of the air conditioner body 2.

[0053] Furthermore, the cooperation between the rotating column 81 and the circular groove 82 provides stable rotational support for the rotating seat 4. The first motor 31 is installed inside the rotating column 81 to achieve structural integration. The second motor 91 provides rotational power, and through the meshing transmission of the drive gear 92 and the internal gear ring 93, it drives the rotating column 81 and the rotating seat 4 to rotate smoothly, thereby driving the air conditioner body 2 to rotate synchronously. This not only ensures the stability and controllability of the rotation process, but also optimizes the overall structural layout of the equipment, realizes flexible adjustment of the air conditioner's air supply direction, and improves the flexibility of equipment use.

[0054] To enable flexible movement of the entire portable air conditioner and meet the position adjustment needs of different usage scenarios, several movable wheels 10 are evenly distributed along the circumference at the lower end of the fixed base 3. As the moving parts of the equipment, the movable wheels 10 can roll flexibly, converting the sliding friction between the fixed base 3 and the ground into rolling friction, which greatly reduces the friction force when the equipment is moved. This allows the operator to easily push the entire air conditioner without expending much effort, enabling the equipment to be quickly moved to different areas indoors. This is suitable for scenarios such as renting a house or temporary office where the air conditioner position needs to be frequently adjusted, fully demonstrating the portability advantage of the portable air conditioner.

[0055] Due to the rolling characteristics of the casters 10, the stability of the equipment is poor when supported solely by the casters 10, making it prone to sliding or tipping over due to uneven ground or accidental collisions. Therefore, adjustable support feet 11 are provided at all four corners of the fixed base 3. These adjustable support feet 11 provide stable support for the equipment, compensating for the insufficient stability of the casters 10. Additionally, a counterweight can be installed inside the fixed base 3. This counterweight lowers the center of gravity of the entire air conditioning unit, further improving its stability and reducing the risk of tipping over.

[0056] The core function of the adjustable support feet 11 is to adapt to different ground flatness levels by adjusting their own height, ensuring the levelness and stability of the equipment when placed. After the equipment is moved to the target position, adjust the four adjustable support feet 11 at the four corners of the fixed base 3 so that the lower end of the adjustable support feet 11 is in close contact with the ground. At the same time, slightly lift the movable wheels 10 so that the movable wheels 10 are off the ground. At this time, the weight of the equipment is entirely supported by the four adjustable support feet 11. The four evenly distributed adjustable support feet 11 can form a stable support structure, effectively limiting the horizontal sliding and tilting of the equipment, preventing the equipment from tipping over due to center of gravity shift or external impact during use, and ensuring the safety of equipment use.

[0057] Furthermore, when the equipment needs to be moved, the adjustable support feet 11 are adjusted to rise off the ground. At this point, the movable wheels 10 are in contact with the ground, allowing the operator to push the equipment and move it flexibly by rolling the wheels 10. After the equipment has moved to the target position, the adjustable support feet 11 are adjusted in the opposite direction to lower them and make them fit snugly against the ground. At the same time, the movable wheels 10 are raised. The stable support of the four adjustable support feet 11 ensures that the equipment is placed stably and prevents it from moving. The movable wheels 10 and the adjustable support feet 11 work together to achieve both convenient movement of the equipment and ensure its stability during use, further improving the practicality and safety of the equipment.
