Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to an air outlet structure and air outlet device. Background Technology

[0002] Fans, as common household appliances, are widely used in homes, offices, and public places. Tower fans, as an important category of fans, are increasingly popular with users due to their unique appearance and small footprint. However, tower fans are generally tall and only have a handle at the top, making them difficult to carry, move, and store when not in use.

[0003] In related technologies, the upper and lower parts of the tower fan are separated, but there are still problems such as the inability to effectively reduce the volume and the difficulty of storage. Summary of the Invention

[0004] Therefore, it is necessary to provide an air outlet structure and air outlet device to address the problem of difficult storage of tower fans.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, embodiments of this application provide an air outlet structure, including:

[0007] The main air outlet has an air outlet section for blowing airflow;

[0008] The outer shell has an internal cavity whose contour matches the shape of the air outlet body;

[0009] The air outlet body is movably disposed relative to the outer casing and has a first state and a second state;

[0010] In the first state, at least a portion of the air outlet is exposed outside the receiving cavity, and the air outlet body is supported on the outer shell;

[0011] In the second state, all of the air outlets are housed within the receiving cavity.

[0012] With the above design, the outer shell is located below the main air outlet during operation to provide support. When stored, the outer shell covers the main air outlet, reducing the overall height of the equipment and shielding the air outlet for protection.

[0013] In one embodiment of the first aspect, the housing includes two opposing half-shells, the two half-shells being detachably connected and engaging to form the receiving cavity.

[0014] The above design facilitates the assembly and disassembly of the outer casing, enabling effective storage and support of the air outlet unit.

[0015] In one embodiment of the first aspect, the air outlet structure further includes a linkage assembly, the linkage assembly including two connecting rods, one end of each of the two connecting rods being rotatably connected to a corresponding half-shell, and the other end being rotatably connected to the peripheral surface of the air outlet body.

[0016] Through the above design, the linkage assembly is connected between the air outlet body and the outer shell to follow the movement of the outer shell and limit the movement trajectory of the outer shell, thereby limiting the position of the outer shell during the support and storage process.

[0017] In one embodiment of the first aspect, the air outlet structure further includes two elastic bands, which are respectively disposed at the upper and lower ends of the outer casing.

[0018] With the above design, after reaching the set position, the two half-shells can be tightly joined together again under the tension of the elastic band.

[0019] In one embodiment of the first aspect, two linkage assemblies are provided, and the two linkage assemblies are disposed opposite to each other on both sides of the air outlet body;

[0020] The two connecting rods of each of the connecting rod assemblies are rotatably connected to the same point of the air outlet body.

[0021] Through the above design, the two sides of the half-shell maintain a force balance, ensuring the stability of the half-shell support.

[0022] In one embodiment of the first aspect, a groove is provided on one side of the air outlet body, and a protrusion is provided on the top of one of the half-shells on the same side as the groove. When the air outlet structure is in the first state, the protrusion passes through the groove.

[0023] The above design facilitates the support and positioning of the outer casing, and also enhances the assembly stability of the outer casing and the air outlet body to a certain extent.

[0024] In one embodiment of the first aspect, a switch is provided in the groove, and the protrusion is inserted into the groove and pressed to turn on the circuit of the air outlet body.

[0025] With the above design, the circuit is in the open state during the second state or the adjustment process between states. During this process, even if the operation button of the air outlet is accidentally touched, the air outlet cannot perform the corresponding operation, thus ensuring the user's safety.

[0026] In one embodiment of the first aspect, the air outlet body has a first end and a second end disposed vertically along a first direction, and the distance between the first end and the second end is L1;

[0027] When the air outlet structure is in the second state, the distance between the top of the half shell and the second end is L2, and satisfies: L1 > L2;

[0028] One end of the connecting rod is connected to the air outlet body at point A, and the other end is connected to the half shell at point B. The vertical distance between point A and the horizontal plane where point B is located is h1.

[0029] The distance between the groove and the second end is h2, and satisfies: L1>2h1+h2.

[0030] With the above design, the top of the air outlet body is exposed outside the outer shell when it is stored. When switching from the second state to the first state, the exposed part of the air outlet body can serve as a force point for the user, which facilitates the downward movement of the half shell after it is separated.

[0031] In one embodiment of the first aspect, the distance between point A and point B is L3, the projection distance between point A and point B along the first direction is d, and satisfies: .

[0032] The above design allows for precise location setting of point A, facilitating industrial production design.

[0033] In one embodiment of the first aspect, the distance between point A and the second end is h3, and satisfies: L2>2h1+h2, h3>h1+h2.

[0034] Through the above design, during the storage of the whole machine, the outer shell still has enough space to cover the groove of the air outlet body, and the groove is used for protection to avoid accidental circuit conduction caused by accidental contact.

[0035] In one embodiment of the first aspect, the air outlet structure further includes a base, which is detachably mounted on the end of the housing away from the air outlet body.

[0036] The above design provides a sealed protection for the bottom of the outer shell, ensuring stable assembly of the two half-shells.

[0037] Secondly, embodiments of this application also provide an air outlet device, including the air outlet structure described in any of the above embodiments.

[0038] The above design meets the storage needs of various air outlet devices, making them easy to carry and move.

[0039] Compared to related technologies, the advantages of this application are as follows: This application provides an air outlet structure and air outlet device, which facilitates the storage of various air outlet devices. The air outlet structure includes an air outlet body and a housing. The air outlet body is the air outlet portion of the device, and the housing is movably disposed relative to the housing. In this way, by moving the housing, the air outlet portion of the air outlet body can be exposed to the outside of the housing or stored within the housing cavity, thereby achieving operational support and storage of the air outlet body. During storage, this application can reduce the overall height of the device, thereby reducing the space occupied, facilitating carrying and storage, and also effectively protecting the air outlet portion.

[0051] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0052] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0053] Furthermore, where the term "and / or" appears, "and / or" merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0054] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0055] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0056] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0057] To facilitate understanding, the air outlet structure provided in this application embodiment is illustrated using a tower fan as an example. Tower fans are generally tall and only have a handle at the top, making them difficult to carry and move, and inconvenient to store when not in use. Related technologies employ a method of separating the upper and lower parts of the tower fan for storage, but this still suffers from the problem of not effectively reducing its size and making storage difficult. Furthermore, the air inlet and outlet are exposed when not in use, making them prone to dust accumulation and requiring frequent cleaning, which is inconvenient for users and also affects their lifespan.

[0058] See Figure 1 As shown, in order to improve the above problems, the embodiments of this application provide an air outlet structure 100, which can reduce the storage volume of the equipment, facilitate storage and movement, and protect the working air outlet.

[0059] For example, the air outlet structure 100 includes an air outlet body 110 and a housing 120. The air outlet body 110 is the air outlet component of the equipment, such as the air supply component of a tower fan or the heating component of a heater. The housing 120 is movable relative to the air outlet body 110. During operation, the housing 120 is located below the air outlet body 110 to provide support. When stored, the housing 120 covers the air outlet body 110 internally, reducing the overall height of the equipment and shielding the working air outlet.

[0060] For example, the air outlet body 110 is provided with an air outlet section 111. When applied to a tower fan, the air outlet section 111 can be the air inlet and air outlet of the tower fan, wherein the air inlet and air outlet are located on two opposite sides of the air outlet body 110. Of course, the air outlet body 110 also contains major working components such as a fan wheel, a motor, and a switch to ensure the normal air supply operation of the air outlet body 110, which will not be described in detail here.

[0061] For example, the housing 120 is coaxially arranged with the air outlet body 110 and has a receiving cavity for accommodating the air outlet body 110. It is understood that the inner diameter of the receiving cavity is slightly larger than the outer diameter of the air outlet body 110 so that the air outlet body 110 can be placed in the receiving cavity.

[0062] In this embodiment, the air outlet structure 100 can be configured into a first state and a second state by moving the outer casing 120 relative to the air outlet body 110. The first state is the normal operating state of the air outlet body 110, and the second state is the retracted state of the air outlet body 110. When the air outlet structure 100 is in the first state, the outer casing 120 is located at the bottom of the air outlet body 110, and the air outlet portion 111 is exposed outside the outer casing 120. When the air outlet structure 100 is in the second state, the outer casing 120 is located covering the outside of the air outlet body 110, and the air outlet portion 111 is concealed within the receiving cavity.

[0063] For example, both the air outlet body 110 and the outer casing 120 are cylindrical structures. In this embodiment, the central axis of the air outlet body 110 is defined as the first direction z. The outer casing 120 can move relative to the air outlet body 110 along the first direction z, so that when the device is operating normally, the outer casing 120 moves to below the air outlet body 110 to support the air outlet body 110 and expose the air outlet 111 to the outside of the receiving cavity. When stored, the outer casing 120 can be moved upward until the air outlet 111 is covered inside the receiving cavity, thereby reducing the overall storage height of the tower fan, reducing the storage volume, and facilitating carrying.

[0064] In some embodiments, one of the housing 120 and the air outlet body 110 is provided with a slide rail, and the other is provided with a slide groove. Both the slide rail and the slide groove are arranged parallel to the first direction z, so that the housing 120 can move relative to the air outlet body 110.

[0065] Continue reading Figure 2 As shown, in some embodiments, the outer casing 120 includes two opposing half-shells 121, which are detachably connected and fit together to form a receiving cavity. The air outlet structure 100 also includes a connecting rod assembly 130, which is connected between the air outlet body 110 and the outer casing 120 to follow the movement of the outer casing 120 and limit the movement trajectory of the outer casing 120, thereby limiting the positioning of the outer casing 120 during support and storage.

[0066] For example, the linkage assembly 130 includes two connecting rods 131, one end of which is rotatably connected to a corresponding half-shell 121, and the other end is rotatably connected to the peripheral surface of the air outlet body 110.

[0067] See also Figure 2 and Figure 3 As shown, when the air outlet structure 100 is in the first state, the two half-shells 121 are joined together at the bottom of the air outlet body 110. At this time, the two connecting rods 131 are in a closed position, and the air outlet 111 is exposed outside the outer shell 120. When it is necessary to store the air outlet body 110, the two half-shells 121 can be separated first, and the two half-shells 121 in the separated state can be driven to move relative to the air outlet body 110 along the first direction z. The two connecting rods 131 follow the movement of the half-shells 121 and rotate relative to the air outlet body 110, opening outward from the closed state, and then moving upward towards each other again until the two connecting rods 131 are joined together again. At this time, the two half-shells 121 are joined together again, so that the air outlet structure 100 is in the second state. When the air outlet structure 100 is in the second state, the two half-shells 121 are joined together to form a receiving cavity, and the air outlet 111 is covered in the receiving cavity.

[0068] For example, both outer shells 120 are provided with semi-circular notches 122, which form a circular hole when assembled. It is understood that the connecting rod 131 is rotatably connected to the air outlet body 110 by a pin, and the pin protrudes from the outside of the air outlet body 110, so that when the air outlet structure 100 is in the second state, the pin is located at the circular hole, so as to avoid the pin interfering with the wall of the outer shell 120 and ensure that the air outlet body 110 can be stored in the outer shell 120.

[0069] In some embodiments, the air outlet structure 100 further includes two elastic bands 140, which are respectively disposed at the upper and lower ends of the housing 120.

[0070] For example, both the upper and lower ends of the two half-shells 121 are provided with semi-circular cavity structures. The upper elastic band 140 passes through the upper cavity of both half-shells 121, and the lower elastic band 140 passes through the lower cavity of both half-shells 121. So that when storing, the two half-shells 121 can stretch the elastic band 140 to separate, and after reaching the set position, the two half-shells 121 are tightly reassembled under the tension of the elastic band 140.

[0071] In other embodiments, the air outlet structure 100 may be provided with only one elastic band 140, and the elastic band 140 may be provided in the middle of the outer shell 120, which can also satisfy the splicing of the two half shells 121.

[0072] In other embodiments, the two half-shells 121 can be provided with snap-fit ​​slots and snap-fit ​​blocks respectively, and the elastic band 140 can be omitted, which can still satisfy the splicing of the two half-shells 121.

[0073] In some embodiments, two linkage assemblies 130 are provided, and the two linkage assemblies 130 are disposed opposite each other on both sides of the air outlet body 110. In this way, the two sides of the half shell 121 maintain force balance, ensuring the stable support of the half shell 121.

[0074] Furthermore, the two connecting rods 131 of each linkage assembly 130 are rotatably connected to the same point of the air outlet body 110, and the connection point is located on the center line of the air outlet body 110, so as to reduce mutual interference between the connecting rods 131 and simplify the overall structure.

[0075] Continue reading Figure 4 and Figure 5 As shown, in some embodiments, a groove 112 is provided on one side of the air outlet body 110, and a protrusion 123 is provided on the top of a half shell 121 on the same side as the groove 112. When the air outlet structure 100 is in the first state, the protrusion 123 passes through the groove 112.

[0076] For example, the groove 112 is located at the bottom of the outer peripheral surface of the air outlet body 110, and the protrusion 123 is disposed on the top inner side of the half-shell 121. In the first state, the outer shell 120 is located at the bottom of the air outlet body 110 and covers the portion of the air outlet body 110 below the air outlet section 111. The protrusion 123 and the groove 112 are interlocked to facilitate the support and positioning of the outer shell 120, and at the same time, it can also enhance the assembly stability of the outer shell 120 and the air outlet body 110 to a certain extent.

[0077] Continue reading Figure 5 and Figure 6 As shown, in some embodiments, a switch 115 is provided in the groove 112. After the protrusion 123 is inserted into the groove 112, the switch 115 is pressed to turn on the circuit 116 of the air outlet body 110.

[0078] For example, the air outlet body 110 is equipped with a corresponding circuit 116 to drive corresponding operations when powered on. The circuit 116 of the air outlet body 110 is switched on and off via a switch 115. Due to the fixed positions of the groove 112 and the protrusion 123, the groove 112 can only be inserted into the air outlet body 110 in the first state. At this time, the circuit 116 of the air outlet body 110 is on, and the operation of the air outlet body 110 can be controlled via the operation button. In the second state or during the adjustment process between states, since the protrusion 123 is not inserted into the groove 112, the circuit 116 is off. During this process, even if the operation button of the air outlet body 110 is accidentally pressed, the air outlet body 110 cannot perform the corresponding operation, ensuring user safety.

[0079] In some embodiments, the switch 115 includes a force-receiving block 1151, a conductive block 1152, and a spring 1153. The conductive block 1152 is fixed to the side of the force-receiving block 1151 opposite to the protrusion 123 and is located at the disconnection point of the circuit 116. The spring 1153 is normally kept in a stretched state, with one end fixed inside the air outlet body 110 and the other end connected to the conductive block 1152 to push the conductive block 1152 and the force-receiving block 1151 outward from the groove 112. At this time, the conductive block 1152 is not in contact with the circuit 116, and the circuit 116 is in a disconnected state. In the first state, the protrusion 123 is inserted into the groove 112 and presses the force-receiving block 1151. At this time, the spring 1153 is in a contracted state, the conductive block 1152 is aligned and in contact with the circuit 116, the circuit 116 is turned on, and the air outlet body 110 can operate normally.

[0080] See again Figure 4 As shown, in some embodiments, the air outlet body 110 has a first end 113 and a second end 114 disposed vertically along a first direction z, and the distance between the first end 113 and the second end 114 is L1. It can be understood that the first end 113 is the top end of the air outlet body 110, and the second end 114 is the bottom end of the air outlet body 110.

[0081] Continue reading Figure 7 As shown, for example, when the air outlet structure 100 is in the second state, the distance between the top of the half-shell 121 and the second end 114 is L2. At the same time, one end of the connecting rod 131 is connected to the air outlet body 110 at point A, and the other end is connected to the half-shell 121 at point B. Point A is located on the center line of the air outlet body 110. Due to the mirrored arrangement of the two half-shells 121, point B and point A are not located on the same vertical line to avoid interference with the splicing of the two half-shells 121.

[0082] For example, the vertical distance between the horizontal planes where point A and point B are located is h1, and the distance between the groove 112 and the second end 114 is h2, satisfying: L1 > 2h1 + h2, L1 > L2. Thus, when the outer casing 120 houses the air outlet body 110, the top of the half-shell 121 is at least partially exposed outside the outer casing 120. Since the top of the air outlet body 110 is exposed outside the outer casing 120 when housed, in some solutions, a handle is provided on the top of the air outlet body 110 to ensure that the handle can still be used in the housed state, facilitating carrying and movement. Simultaneously, when transitioning from the second state to the first state, the exposed portion of the air outlet body 110 can serve as a force point for the user, facilitating the downward movement of the half-shell 121 after separation.

[0083] In some embodiments, the distance between point A and point B is L3, the projection distance between point A and point B along the first direction z is d, and satisfies: .

[0084] For example, the length L3 of the connecting rod 131 is a fixed value, while point A needs to be on the center line of the half shell 121. The position setting of point A can be accurately obtained through the above formula, which is convenient for industrial production design.

[0085] In some embodiments, the distance between point A and the second end 114 is h3, and satisfies: L2>2h1+h2, h3>h1+h2. Thus, during the storage of the entire unit, after the outer casing 120 moves upward by a distance of two h3, there is still room to cover the groove 112 of the air outlet body 110, and the groove 112 provides protection to prevent accidental contact from causing the circuit 116 to be turned on.

[0086] In some embodiments, the air outlet structure 100 further includes a base 150, which is detachably mounted on the end of the housing 120 away from the air outlet body 110.

[0087] For example, the base 150 can be fixed to the bottom of the outer shell 120 by bolts, thus providing a sealed protection for the bottom of the outer shell 120. At the same time, after the two half-shells 121 are fixed to the outer shell 120, they remain in a spliced ​​state, achieving stable assembly of the two half-shells 121.

[0088] Understandably, when transitioning between states, the base 150 can be removed from the outer shell 120 first, and then the two half-shells 121 can be separated and moved.

[0089] Embodiments of this application also provide an air outlet device, including the air outlet structure 100 in any of the above embodiments.

[0090] For example, the air outlet device can be one of the following: a fan, an electric heater, an air purifier, a humidifier, etc. For ease of understanding, the embodiments of this application will only use a tower fan as an example for illustration.

[0091] This embodiment has the air outlet structure 100 of any of the above embodiments, and therefore has all the beneficial effects of the air outlet structure 100 of any of the above embodiments, which will not be described in detail here.

[0092] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0093] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
