Description

Technical Field

[0001] This application relates to the field of tower fan technology, and more particularly to a tower fan. Background Technology

[0002] In practical applications of traditional tower fans, especially in densely populated environments, existing tower fans generally use a single-axis oscillation to deliver airflow in different directions. While this design can expand the airflow range to some extent, it has significant limitations. When the tower fan is blowing in a specific direction, people in other directions can only passively wait for the fan to complete its oscillation and turn to the corresponding direction before they can feel the airflow. This process not only leads to excessively long waiting times but also fails to meet the needs of people in different directions to enjoy suitable airflow simultaneously, greatly impacting the user experience. Utility Model Content

[0003] This application provides a tower fan to solve the technical problem in the prior art where people in other directions have long waiting times and cannot enjoy suitable airflow simultaneously when the tower fan swings as a whole.

[0004] This application provides a tower fan, including a housing, wherein at least two air outlets are provided on one side of the housing along its height direction, and each air outlet is provided with an air direction adjustment component;

[0005] The air direction adjustment components of each air outlet can be controlled independently, so that different air outlets can simultaneously deliver air in different directions, achieving simultaneous air delivery to multiple areas.

[0006] In one possible implementation, the wind direction adjustment assembly includes a drive component, an eccentric wheel, a connector, and several guide vanes. The guide vanes are rotatably connected to the connector via a first connecting shaft. The drive component drives the eccentric wheel to rotate, thereby causing the connector to reciprocate and move, which in turn drives the guide vanes to rotate.

[0007] In one possible implementation, the air guide vanes extend along the height direction of the housing.

[0008] In one possible implementation, the connector is provided with a through hole, and the eccentric wheel is inserted into the through hole and can rotate within the through hole to cause the connector to reciprocate.

[0009] In one possible implementation, the housing is provided with fixing plates at both ends near the air guide blades, and the air guide blades are provided with second connecting shafts at both ends. The second connecting shafts pass through the fixing plates and are rotatably connected to the fixing plates.

[0010] In one possible implementation, the fixing plate near the connector is provided with a groove for the first connecting shaft to move.

[0011] In one possible implementation, a blower is also included, with an air inlet on the other side of the housing, and the blower is rotatably disposed within the housing and located between the air inlet and the air outlet.

[0012] In one possible implementation, a protective net is provided between the blower and the air outlet.

[0013] In one possible implementation, a base is also included, on which the housing is rotatably mounted.

[0014] The technical solutions provided in this application have the following advantages compared with the prior art:

[0015] The tower fan provided in this application embodiment has at least two air outlets along the height direction on one side of the casing, and each air outlet is equipped with an air direction adjustment component. By independently controlling the air direction adjustment component of each air outlet, the air delivery direction of each air outlet can be changed, so that different air outlets can deliver air in different directions at the same time, thereby achieving the effect of simultaneous air delivery to multiple areas.

[0016] This design solves the problem of long waiting times for people in other directions and the inability to enjoy suitable airflow simultaneously when traditional tower fans oscillate as a whole, greatly improving the user experience, meeting the needs of people in different directions to enjoy airflow at the same time, and enhancing the practicality and applicability of tower fans.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0029] For ease of description, spatial relative terms may be used in this text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the tower fan during use or operation, in addition to those depicted in the figure. For example, if the tower fan in the figure undergoes a positional flip, attitude change, or movement change, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The tower fan may be oriented in other ways (rotated 90 degrees or in other directions), and the spatial relative descriptors used in this text will be interpreted accordingly.

[0030] To address the technical problem in existing tower fans that cause long waiting times for people in other directions and prevent them from simultaneously enjoying suitable airflow when the tower fan swings its head as a whole, this application provides a tower fan that meets the needs of people in different directions to enjoy airflow at the same time, thereby enhancing the practicality and applicability of the tower fan.

[0031] Figures 1 to 3 A tower fan provided in this application embodiment includes a housing 1, and at least two air outlets 101 are provided on one side of the housing 1 along its height direction, and each air outlet 101 is provided with an air direction adjustment component 2;

[0032] The air direction adjustment components 2 of each air outlet 101 can be controlled independently, so that different air outlets 101 can simultaneously deliver air in different directions, realizing simultaneous air delivery to multiple areas.

[0033] In the above technical solution, at least two air outlets 101 are provided on one side of the tower fan casing 1 along the height direction, and each air outlet 101 is equipped with an air direction adjustment component 2. The air direction adjustment component 2 can control the air delivery direction of the corresponding air outlet 101, and the air direction adjustment component 2 of each air outlet 101 can be controlled independently. When users have different air delivery needs for different areas, by operating each air direction adjustment component 2 separately, different air outlets 101 can simultaneously deliver air in their respective desired directions, thereby achieving the effect of simultaneous air delivery to multiple areas.

[0034] Compared to the traditional tower fan's single oscillating air supply method, the air direction adjustment component 2 of each air outlet 101 of the tower fan in this application is independently controlled, which can flexibly adjust the air supply direction of each air outlet 101 according to the location and needs of people in different areas, so as to meet diverse air supply scenarios.

[0035] At the same time, it avoids the problem of people in other directions waiting for airflow when using traditional tower fans. People in different areas can enjoy suitable airflow at the same time without having to wait for a long time, which greatly improves the comfort and satisfaction of users using tower fans.

[0036] For example, please refer to Figure 1 The housing 1 is provided with two air outlets 101 (upper air outlet 1011 and lower air outlet 1012). For a person sitting next to it who is being blown by the air, the upper air outlet 1011 and the lower air outlet 1012 can blow air onto the person at the same time, providing a comfortable feeling all around.

[0037] For special groups such as the elderly and those with cold legs and feet, the airflow adjustment component 2 can direct the airflow from the upper air outlet 1011 towards the body, while the lower air outlet 1012 avoids direct airflow. This design allows the upper part of the body to feel cool while avoiding discomfort in the legs due to direct airflow, reflecting the product's humanized design.

[0038] Furthermore, when the user is sitting on the ground, the lower airflow is directed towards the person, while the upper airflow avoids direct airflow. This flexible airflow method can be adjusted according to the user's different postures and positions to meet diverse usage scenarios.

[0039] Please refer to Figure 2 In one possible implementation, the wind direction adjustment component 2 includes a drive component 201, an eccentric wheel 202, a connector 203, and a plurality of wind guide blades 204. The wind guide blades 204 are rotatably connected to the connector 203 via a first connecting shaft 2041. The drive component 201 drives the eccentric wheel 202 to rotate so as to drive the connector 203 to move back and forth, thereby driving the wind guide blades 204 to rotate.

[0040] The airflow adjustment assembly 2 consists of a drive unit 201, an eccentric wheel 202, a connector 203, and several guide vanes 204. When it is necessary to adjust the airflow direction, the drive unit 201 starts working, driving the eccentric wheel 202 to rotate. Since the guide vanes 204 are rotatably connected to the first connecting shaft 2041 and the connector 203, the rotation of the eccentric wheel 202 will drive the connector 203 to reciprocate. The reciprocating movement of the connector 203 further drives the guide vanes 204 to rotate around the first connecting shaft 2041. After the guide vanes 204 rotate, they change the outflow direction of the airflow, thereby achieving the adjustment of the airflow direction of the air outlet 101.

[0041] Understandably, through the mechanical linkage of the drive component 201, eccentric wheel 202, connector 203 and guide vane 204, the rotation angle of the guide vane 204 can be controlled, thereby achieving precise adjustment of the air delivery direction and meeting the personalized needs of different users for the air delivery direction.

[0042] It should be noted that the guide vane 204 extends along the height direction of the housing 1. When the blower 3 draws air into the housing 1 from the air inlet, the airflow flows within the housing 1. Because the guide vane 204 extends along the height direction, its greater length allows it to more comprehensively contact the airflow delivered from the blower 3. When the connector 203 drives the guide vane 204 to rotate, the guide vane 204 guides the airflow along its extension direction and the angle formed by the rotation to exit through the air outlet 101, thereby achieving adjustment of the airflow direction and range.

[0043] In other words, the guide vanes 204 extending along the height of the casing 1 can cover a larger vertical space, enabling the tower fan to deliver air evenly in the vertical direction. Airflow can be felt in both higher and lower spaces, significantly expanding the air delivery range compared to traditional designs, making it particularly suitable for spaces with large ceiling heights, such as shopping malls and auditoriums.

[0044] Please refer to Figure 2 and Figure 3 The connector 203 has a through hole 2031, and the eccentric wheel 202 is inserted into the through hole 2031 and can rotate within the through hole 2031 to cause the connector 203 to reciprocate. When the drive member 201 drives the eccentric wheel 202 to rotate, due to the eccentricity of the eccentric wheel 202, its rotation center does not coincide with its geometric center. During rotation, the eccentric wheel 202 rotates within the through hole 2031, and its outer edge interacts with the inner wall of the through hole 2031, generating a driving force that causes the connector 203 to reciprocate horizontally or in a specific direction. This reciprocating movement provides the power basis for subsequently driving the guide vane 204 to rotate, thereby achieving airflow direction adjustment. In one possible embodiment, the through hole 2031 of this application is designed as an ellipse with one end open.

[0045] Please refer to Figure 1 and Figure 3 In one possible implementation, the housing 1 has fixing plates 102 at both ends near the guide vane 204, and second connecting shafts 2042 at both ends of the guide vane 204. The second connecting shafts 2042 pass through the fixing plates 102 and are rotatably connected to them. When the connector 203 drives the guide vane 204 to rotate, the second connecting shafts 2042 at both ends of the guide vane 204 rotate on the fixing plates 102, allowing the guide vane 204 to rotate around the axis of the second connecting shafts 2042, thereby changing the airflow direction and adjusting the air delivery direction.

[0046] The fixed plate 102 provides a stable support structure for the air guide blade 204, ensuring that the air guide blade 204 will not wobble or deviate during rotation, thus guaranteeing the stability and reliability of the air guide blade 204 and making the adjustment of the air delivery direction more accurate.

[0047] Please refer to Figure 3 In one possible implementation, the fixing plate 102 near the connector 203 is provided with a groove 1021 for the first connecting shaft 2041 to move. When the driving member 201 drives the eccentric wheel 202 to rotate, causing the connector 203 to reciprocate, the first connecting shaft 2041 will move along with the connector 203 because the guide vane 204 is rotatably connected to the connector 203 through the first connecting shaft 2041. At this time, the groove 1021 on the fixing plate 102 provides a track for the first connecting shaft 2041 to move. The first connecting shaft 2041 slides in the groove 1021, allowing the connector 203 to smoothly drive the guide vane 204 to rotate, thereby adjusting the airflow direction of the air outlet 101. Compared with free movement without a track, the design of the groove 1021 reduces the friction and collision between the first connecting shaft 2041 and surrounding components, reduces the wear of the first connecting shaft 2041 and related components, extends the service life of the components, and reduces maintenance costs.

[0048] It should be noted that this application also includes a blower 3. An air inlet (not shown in the attached drawings) is provided on the other side of the housing 1. The blower 3 is rotatably mounted inside the housing 1 and located between the air inlet and the air outlet 101. When the tower fan is running, external air enters the housing 1 through the air inlet on the other side of the housing 1. At this time, the blower 3, located between the air inlet and the air outlet 101, begins to rotate. During rotation, the blades of the blower 3 exert a force on the air entering the housing 1, propelling the air to flow within the housing 1, drawing the air in from the air inlet and accelerating it, then conveying it towards the air outlet 101, ultimately causing the accelerated airflow to be blown out from the air outlet 101, thus realizing the tower fan's air delivery function.

[0049] A protective mesh 5 is installed between the blower 3 and the air outlet 101. During tower fan operation, the protective mesh 5 effectively prevents small particles of foreign matter such as dust, hair, and paper scraps from entering the area between the blower 3 and the air outlet 101. If these foreign objects enter the blower 3, they may become entangled on the blades, affecting the normal rotation of the blower 3, reducing air delivery efficiency, and may even damage the blower 3, increasing maintenance costs. The presence of the protective mesh 5 can greatly reduce the occurrence of this situation and extend the service life of the tower fan.

[0050] For families with children or pets, the protective net 5 can also prevent them from sticking their fingers, toys, or other items into the air outlet 101, avoiding accidental injuries and ensuring the safety of users.

[0051] In one possible implementation, a base 4 is also included, on which the housing 1 is rotatably mounted. The base 4 provides a stable support foundation for the tower fan, and the housing 1 is rotatably mounted on the base 4 via a specific rotatable connection structure (such as a motor, shaft, bearing, etc.). When the user needs to adjust the airflow angle of the tower fan, the housing 1 can be manually or electrically pushed to rotate around the central axis of the base 4. Due to the rotatable connection between the housing 1 and the base 4, the housing 1 can rotate flexibly on the base 4, thereby changing the orientation of the air outlet 101, further expanding the airflow range of the tower fan, and meeting the airflow needs of different areas and angles.

[0052] It should be noted that when the unit is not oscillating, the air guide vane 204 can adjust the airflow direction to about 60°. Users can adjust the airflow direction according to their needs and preferences to obtain the most comfortable air supply effect.

[0053] When the unit is oscillating, the additional 204 air guide vanes enable wide-area air delivery, allowing for a wider area to enjoy the breeze. Whether for multiple people or to cover a larger space, it can be easily achieved.

[0054] When in use, the air outlet 101 can be adjusted to different directions or the same direction. When adjusted to different directions, it can create more complex airflow, accelerating the flow and exchange of indoor air; when adjusted to the same direction, it can concentrate the airflow and enhance the air circulation effect. This design helps to circulate air throughout the house, effectively optimizing the indoor air environment and making the indoor air fresher and more comfortable.
