A modular tower fan 100 according to an embodiment of the invention is described below with reference to fig. 1-6.

As shown in fig. 1, a modular tower fan 100 according to an embodiment of the present invention includes: a base 1, a fan unit 2, and a rotation driving device 3.

The base 1 is used for carrying the whole modular tower fan 100. The number of the fan units 2 is at least one, the fan units 2 are detachably assembled on the top of the base 1, and when the number of the fan units 2 is multiple, the fan units 2 are sequentially detachably assembled along the height direction.

As shown in fig. 2 and 3, the rotation driving device 3 includes: the driving member 32 is connected to the driving member 33, and the driving member 33 drives the driving member 32 to generate a rotational motion or a linear motion, etc., where the motion form of the driving member 32 is not limited. When the driving member 32 is engaged with the driven rotating member 31, the driven rotating member 31 can be driven to rotate relatively.

In this application, a set of rotation driving device 3 is connected between the fan unit 2 and the base 1. When the fan units 2 are multiple, another set of rotation driving device 3 is connected between every two adjacent fan units 2, and each set of rotation driving device 3 includes: a passive rotating member 31 and an active member 32, and a driving member 33 connected to the active member 32. When the modular tower fan 100 is provided with two sets of rotation driving devices 3, the two sets of rotation driving devices 3 operate independently.

In the solution of the present application, the rotation driving device 3 has at least two arrangements, as shown in the first arrangement in fig. 5 and the second arrangement in fig. 6. For the convenience of observation, the passive rotating member 31 is simplified as a, the active member 32 is simplified as B, and the driving member 33 is simplified as C in the two diagrams. As shown in fig. 5, in the first configuration, the base 1 and each fan unit 2 are provided with a passive rotating member 31 (a in fig. 5), and each fan unit 2 is provided with an active member 32 and a driving member 33 (B and C in fig. 5). In the second configuration, the base 1 and each fan unit 2 are provided with an active component 32 and a driving component 33 (B and C in fig. 6), and each fan unit 2 is provided with a passive rotating component 31 (a in fig. 6).

In the first and second setting forms, when the fan unit 2 is assembled on the base 1, a set of rotation driving device 3 can be formed between the two, the passive rotating member 31 and the active member 32 between the two can be matched, and the driving member 33 drives the passive rotating member 31 to rotate relative to the driving member 33 when driving the active member 32 to move, so as to drive the fan unit 2 to rotate relative to the base 1.

In the first and second setting forms, when two adjacent fan units 2 are assembled, a set of rotation driving device 3 can be formed between the upper and lower fan units 2, the passive rotating part 31 and the active part 32 between the upper and lower fan units 2 are matched, and the driving part 33 drives the passive rotating part 31 to rotate relative to the driving part 33 when driving the active part 32 to move, so that the upper fan unit 2 is driven to rotate relative to the lower fan unit 2.

That is, in both arrangements, a passive rotating member 31, an active member 32, and a driving member 33 are connected to each fan unit 2. The driving part 32 is connected with the driving part 33 and belongs to the same set of rotation driving device 3. The passive rotating part 31 and the active part 32 on the same fan unit 2 do not belong to the same set of rotation driving device 3. The passive rotating member 31 of one fan unit 2 is engaged with the active member 32 of the base 1 or the other fan unit 2, and the active member 32 of one fan unit 2 is engaged with the passive rotating member 31 of the base 1 or the other fan unit 2.

In the prior art, a plurality of fan units are arranged on a tower fan in some schemes, and although the fan units can be detached, if the air outlet direction of each fan unit needs to be adjusted, the fan units need to be manually adjusted, and the use is inconvenient. If the rotating shaft is arranged on the base, the rotating shaft is utilized to drive the fan units to rotate to change the direction, and at the moment, the plurality of fan units synchronously rotate, so that the operation mode is single.

In order to solve the above problems, the present disclosure provides a modular tower fan 100, which can realize a multi-element blowing mode. For simplicity, the structure and usage of the modular tower fan 100 will be described below by taking the first configuration as an example, and those skilled in the art can directly derive the structure and usage of the modular tower fan 100 in the second configuration.

Specifically, when the fan unit 2 is assembled on the base 1, a set of rotation driving devices 3 is formed between the fan unit 2 and the base 1. Because the base 1 is provided with the passive rotating part 31, and the fan unit 2 is provided with the driving part 33 and the driving part 32 which are connected, the driving part 32 on the fan unit 2 can be rotatably matched with the passive rotating part 31 on the base 1. After the rotation driving device 3 is formed in this way, when the driving element 33 drives the driving element 32 to move, the driving element 32 and the driven rotating element 31 are in a rotation fit action, so that the driven rotating element 31 rotates relative to the driving element 33, and since the driven rotating element 31 is fixed on the base 1, the fan unit 2 provided with the driving element 33 rotates relative to the base 1, thereby realizing the rotation of the fan unit 2. When the fan unit 2 is rotatable, the blowing direction of the fan unit 2 can be changed, and the blowing range of the fan unit 2 is expanded. When the rotation range of the fan unit 2 is limited within the set angle, the fan unit 2 can perform a large-angle air supply within the set angle. When the fan unit 2 can rotate at least one turn, the fan unit 2 can supply air at a full angle.

There are solutions in which the modular tower fan 100 has a plurality of fan units 2, each fan unit 2 being independently operable. Because the plurality of fan units 2 are individually assembled, the modular tower fan 100 can also meet the blowing requirements of people at different positions by adjusting the directions of the plurality of fan units 2. Even in some schemes, when the wind speeds or wind sensations of the fan units 2 are different, the modular tower fan 100 can obtain different wind speeds and wind sensations to meet the requirements of different people on the wind speed and wind sensations. Here, the plurality of fan units 2 may have different wind speeds or wind sensations, and may be fixedly installed in the respective fan units 2, or the wind speeds or wind sensations of the respective fan units 2 may be set to be adjustable, so that the user can adjust the respective fan units 2 to desired wind speeds or wind sensations.

In the solution of the present application, when the modular tower fan 100 has a plurality of fan units 2, one of the fan units 2 can be assembled on the base 1, and the remaining fan units 2 are assembled on the fan unit 2 in sequence along the height direction. The manner of assembly between the lowermost fan unit 2 and the base 1 will not be described in detail here. The fan unit 2 can rotate relative to the base 1, and the air supply range of the fan unit 2 can be expanded.

When the upper fan unit 2 is assembled on the lower fan unit 2, a set of rotation driving devices 3 is formed between the upper fan unit 2 and the lower fan unit 2. Since the lower fan unit 2 is provided with the passive rotating member 31 and the upper fan unit 2 is provided with the driving member 33 and the active member 32 connected thereto, the active member 32 of the upper fan unit 2 can be engaged with the passive rotating member 31 of the lower fan unit 2. In this way, when the driving member 32 is driven to move, since the driven rotating member 31 is fixed on the lower fan unit 2, the upper fan unit 2 provided with the driving member 33 rotates relative to the lower fan unit 2, and the upper fan unit 2 rotates. When the upper fan unit 2 is rotatable, the blowing direction of the upper fan unit 2 can be changed, and the blowing range of the upper fan unit 2 is expanded. Of course, when the modular tower fan 100 has two upper and lower fan units 2, both fan units 2 can rotate, and the rotation speed and direction of the upper fan unit 2 are influenced by the rotation speed and direction of the lower fan unit 2.

According to the scheme of the application, each fan unit 2 is provided with the passive rotating part 31 and the active part 32, and the driving part 33 connected with the active part 32, and each time one fan unit 2 is assembled on the base 1, the fan unit 2 and the base 1 below or another fan unit 2 below form a set of rotation driving device 3 which can rotate relative to the base 1 below or another fan unit 2 below. The user can make the adjustment to the rotation speed and the direction of every fan unit 2 according to the in-service use condition for modular tower fan 100 air supply mode is more many, can supply air to the multi-angle simultaneously, improves modular tower fan 100's air supply flexibility.

In this application, the passive rotating member 31 is engaged with the active member 32, so that not only the fan unit 2 can rotate relative to the base 1 or the other fan unit 2, but also the fan unit 2 can be detachably spliced with the base 1 or the other fan unit 2, and a user can add the fan unit 2 or reduce the fan unit 2 according to actual use conditions. It can be understood that the modular tower fan 100 needs at least one fan unit 2 to achieve normal operation, and on this basis, the user can add the fan unit 2 according to actual conditions to make the modular tower fan 100 perform more air supply.

Even if the modular tower fan 100 includes only one fan unit 2, multiple uses may be designed as desired. For example, when the rotation of the fan unit 2 is not required, the fan unit 2 may be detached from the base 1, and the fan unit 2 may be used alone to reduce the occupied space. For another example, a family can purchase two modular tower fans 100, one modular tower fan 100 can be used when two members of the family are distributed to two rooms, one modular tower fan 100 can be combined when two members of the family are in one room, that is, the fan unit 2 of one modular tower fan 100 is disassembled and assembled to the other modular tower fan 100, the occupied space of the assembled modular tower fan 100 is smaller than that of two independent modular tower fans 100, different blowing experiences can be obtained by utilizing the autorotation driving devices 3 corresponding to the two fan units 2 on the assembled modular tower fan 100, and the fan unit 2 above the assembled modular tower fan is raised to blow air at a high place.

To sum up, the utility model discloses module tower fan 100, through setting up rotation drive arrangement 3, every fan unit 2 of assembling on the base 1, this fan unit 2 just can constitute one set of rotation drive arrangement 3 with between base 1 of below or another fan unit 2, it can be relative the base 1 of below or another fan unit 2 of below rotate, this fan unit 2 can carry out wide-angle air supply or full angle air supply, make module tower fan 100 produce the air supply mode of many units, it is more intelligent to use, it is convenient. Because each fan unit 2 can be assembled on the base 1, each fan unit 2 can independently operate, and the use is very flexible. Moreover, when there are a plurality of fan units 2, the user can select the number of the fan units 2 according to the requirement, and can adjust and obtain a plurality of blowing angles according to the requirement, and even can obtain a plurality of wind senses or wind speeds in some schemes.

In the solution of the present application, the form of the drive 33 is not limited. In some alternative embodiments, the driving member 33 is a motor, such as a linear motor or a rotary motor. In other alternative embodiments, the driving member 33 is a cylinder, and a piston of the cylinder is connected to the driving member 32 to drive the driving member 32 to reciprocate, so that the fan unit 2 can rotate in forward and reverse directions alternately.

In the solution of the present application, the structure of the driving element 32 may also be unlimited, as long as the driving element can drive the driven rotating element 31 to rotate relatively when moving.

For example, in some alternative embodiments, the driving member 32 is a friction wheel, and the driven rotating member 31 is another friction wheel. When the base 1 is spliced with the fan unit 2 or the two fan units 2 and a set of autorotation driving device 3 is formed between the two spliced parts, the peripheries of the two friction wheels are in contact, and the driving part 32 rotates to drive the driven rotating part 31 to rotate.

For example, in other alternative embodiments, the driving member 32 is a spindle, the driven rotating member 31 is a rotating wheel, and the center of the rotating wheel is provided with a socket. When the base 1 is spliced with the fan unit 2 or the two fan units 2 and a set of autorotation driving device 3 is formed between the two spliced parts, the inserting shaft is inserted into the jack of the rotating wheel and is in non-rotating fit with the jack, and when the driving piece 33 drives the inserting shaft to rotate, the inserting shaft drives the rotating wheel to rotate relative to the driving piece 33.

In some embodiments, the driven rotating member 31 is a driven gear, and the driven rotating member 31 and the driving member 32 are engaged in a meshing manner. By means of the meshing transmission cooperation, the transmission ratio can be adjusted by means of the number of teeth, so that the driven rotating member 31 can reach a proper rotating speed. And compared with the friction transmission, the reliability and the stability of the engagement transmission are higher.

When the driven rotating element 31 and the driving element 32 are in meshing transmission, the transmission may be gear transmission, gear-rack transmission, or worm-gear transmission, and this is not limited here.

In some embodiments, as shown in fig. 3, the driven rotating member 31 is a ring gear, and the driving member 32 is a driving gear. By such an arrangement, the speed reduction ratio can be increased, and thus a common motor is selected as the driving member 33, so that the rotation speed of the fan unit 2 is low, and the stability is kept.

When the rotation driving device 3 meets the setting form, the top of the base 1 and the top of each fan unit 2 are both provided with an inner gear ring, and the bottom of each fan unit 2 is provided with a driving gear. When the fan unit 2 is assembled, the driving gear at the bottom of the fan unit 2 is meshed with the lower base 1 or the inner gear ring at the top of the fan unit 2.

When the rotation driving device 3 meets the second setting form, the top of the base 1 and the top of each fan unit 2 are both provided with driving gears, and the bottom of each fan unit 2 is provided with an inner gear ring. When the fan unit 2 is assembled, the inner gear ring at the bottom of the fan unit 2 is meshed with the driving gear at the bottom of the lower base 1 or the top of the fan unit 2.

Here, the ring gear and the driving gear are disposed at the top and bottom of the fan unit 2, so that the ring gear and the driving gear are easily engaged with each other during assembly.

The driven rotating part 31 is arranged as an inner gear ring, and the diameter of the inner gear ring can be larger, so that the transmission torque can be reduced, and the pressure at the transmission matching part can be reduced.

Further, as shown in fig. 2, when the top of the base 1 and the top of each fan unit 2 are both provided with an inner gear ring, the bottom of each fan unit 2 may also be provided with a matching ring 34, and the matching ring 34 is sleeved outside and matched with the cylindrical surface of the inner gear ring.

When the bottom of each fan unit 2 is provided with an inner gear ring, a matching ring 34 can be arranged on the top of the base 1 and the top of each fan unit 2, and the matching ring 34 is sleeved outside and matched with the cylindrical surface of the inner gear ring.

By arranging the matching ring 34, the matching ring 34 is matched with the cylindrical surface of the inner gear ring, so that when the fan unit 2 is assembled, the matching ring 34 can be used for being matched with the cylindrical surface of the inner gear ring for guiding, and when the two cylindrical surfaces are matched in place, the inner gear ring and the driving gear can be matched in place, so that the fan unit 2 can be assembled more smoothly.

The matching ring 34 is matched with the cylindrical surface of the inner gear ring, so that the fan unit 2 can rotate smoothly, the gear gap between the inner gear ring and the driving gear can be kept stable, and the phenomena of gear clamping and the like caused by the shaking of the fan unit 2 are avoided.

In addition, the arrangement can ensure that the fan unit 2 is spliced with the base 1 provided with the inner gear ring or the other fan unit 2 provided with the inner gear ring more firmly, and the problem of connection and disconnection is not easy to occur.

It can be understood that when the matching ring 34 is matched with the cylindrical surface of the inner gear ring, a part for assisting the matching ring 34 to rotate relative to the inner gear ring can be added between the matching ring 34 and the cylindrical surface of the inner gear ring, so that the friction force between the matching ring 34 and the cylindrical surface of the inner gear ring is reduced, the rotation of the fan unit 2 relative to the inner gear ring is easier, and the energy consumed by the rotation of the fan unit 2 is reduced.

Alternatively, when the fitting ring 34 is provided on the base 1, the fitting ring 34 may be integrally formed on the outer shell of the base 1. When the fitting ring 34 is provided on the fan unit 2, the fitting ring 34 may be integrally formed on the fan case 21.

In some embodiments, as shown in FIG. 1, the modular fan 100 further includes a cover plate 4, and the cover plate 4 is disposed on top of the fan unit 2 for decoration.

Specifically, the cover plate 4 is detachably attached to the top of the fan unit 2. When the fan unit 2 is plural, the cover plate 4 is detachably attached to the top of the uppermost fan unit 2. Because fan unit 2 top is provided with passive rotation piece 31 or active part 32, assembles apron 4 on the fan unit 2 of the top, can shelter from passive rotation piece 31 or active part 32 on the one hand, play and decorate pleasing to the eye effect, on the other hand can prevent that debris from falling to fan unit 2's top, reduces fan unit 2 top passive rotation piece 31 or active part 32 impaired probability, has also reduced debris and has piled up and lead to the cleaning degree of difficulty.

In some embodiments, a rotation driving device 3 is also provided between the cover plate 4 and the uppermost fan unit 2 to rotate the cover plate 4 relative to the fan unit 2. This arrangement allows the cover plate 4 to be used more.

For example, when the fan unit 2 rotates forward relative to the base 1, the cover 4 may rotate backward relative to the fan unit 2, and when the rotation speeds of the two are the same, the cover 4 is stationary relative to the base 1. Therefore, the cover plate 4 can be in a static state relative to a user, and the use by the user is convenient.

When the fan unit 2 is provided with the passive rotation member 31 at the top, the cover plate 4 may be provided with the driving member 33 and the active member 32 connected thereto. When the cover plate 4 is assembled on the fan unit 2, the driving member 32 of the cover plate 4 is engaged with the driven rotating member 31 of the fan unit 2, and the driving member 33 drives the cover plate 4 to rotate relative to the fan unit 2 when the driving member 32 is driven to move. Accordingly, when the fan unit 2 connected to the cover 4 is rotated, the cover 4 can be rotated in a different direction or speed from the fan unit 2 by the driving of the driving member 33, and can also be rotated in the same direction or speed as the connected fan unit 2. The user can adjust the rotation of the cover plate 4 according to actual conditions.

Similarly, when the top of the fan unit 2 is provided with the driving member 33 and the driving member 32, the cover plate 4 may be provided with the passive rotation member 31.

In some embodiments, the modular tower fan 100 further includes a control module 5 disposed on the cover plate 4, and the control module 5 is electrically connected to the fan unit 2. The control module 5 is able to control the drives 33 of each fan unit 2 by which a user can control the rotation pattern of the individual fan units 2. When the modular tower fan 100 has a plurality of fan units 2, the control module 5 may control all the fan units 2 to rotate at the same speed or angle, or may control one of the fan units to rotate independently, or may control the plurality of fan units 2 to rotate in the same direction or at different speeds. Through the control module 5, a user can more conveniently adjust the operation mode of the fan unit 2, thereby controlling the operation mode of the entire modular tower fan 100 to be more diversified.

It is contemplated that the control module 5 may preset some operating modes of the modular tower fan 100, such as one or more fan units 2 rotating or not rotating at a set speed and direction. It is also possible that all fan units 2 owned by the modular tower fan 100 are rotated simultaneously at the same speed or direction, or not. The preset operation mode may be an operation mode that is already set when the modular tower fan 100 leaves a factory, or may be a plurality of preference operation modes that are added by a user according to actual situations when the user uses the modular tower fan, and the user can quickly execute the set operation mode of the tower fan by sending an instruction to the control module 5, thereby reducing the complexity of operation of the operator.

In the solution of the present application, the structural form of the control module 5 may also vary.

For example, the control module 5 may include a control screen disposed on the cover 4, and the user may directly observe the operation status of the modular tower fan 100 on the control screen, and the user may directly input control information on the control screen.

For another example, the control module 5 includes a remote control that is removably attached to the cover 4 such that the remote control is placed on the control module 5 when not in use and removed when in use.

In this way, a user inputs a control instruction through a control screen arranged on the cover plate 4 or a remote controller detachably connected to the cover plate 4, thereby realizing control of each fan unit 2 through the control module 5. Conceivably, control panel and remote controller all can be equipped with and predetermine the button, predetermines the button and can directly change the operational mode of modular tower fan 100 into the operational mode that predetermines for user's operation is more convenient, reduces user's operation complexity.

Conceivably, the cover plate 4 can be separately provided with a control screen or detachably connected with a remote controller, and the control screen and the remote controller can also be simultaneously arranged. Meanwhile, the size and the shape of the control screen and the remote controller can be adjusted according to the actual use condition. The control screen or the remote controller can facilitate the operation of the modular tower fan 100 by a user, and reduce the operation time of the user.

Optionally, when a remote controller is provided, a groove may be provided on the cover plate 4 for placing the remote controller.

Of course, the control method of the present application is not limited to the above-mentioned scheme, and for example, the control module 5 may be provided on the base 1, or the control module 5 may be directly provided on each fan unit 2.

In some embodiments, as shown in fig. 2 and 4, the fan unit 2 includes: fan case 21, wind wheel assembly 22 and air deflector 23. The fan housing 21 is provided with an air inlet 214 and an air outlet 215, and the air wheel assembly 22 is arranged in the fan housing 21. The air deflector 23 is movably disposed at the air outlet 215. Air enters the fan unit 2 through the air inlet 214, flows through the air wheel assembly 22 and flows out through the air outlet 215, so that air supply of the fan unit 2 is realized.
