TECHNICAL FIELD

[0001] The utility model relates to fan technical field, specifically, a cool and warm fan. BACKGROUND

[0002] At present, the fan of vertical air outlet can only realize the adjustment of air supply direction through the left and right swing of the whole machine, and for the scene of up and down air adjustment demand, the related technology usually separately sets multiple blades and corresponding linkage connecting rods on the air outlet surface, and when adjusting, the orientation of the blade can be manually adjusted to realize the adjustment of the air direction, or some products increase a manual lever for convenient adjustment, but in the process of levering, the blade rotates, so that the movement track of the lever is an arc, and when the blade rotates to different positions, the protruding height of the lever is inconsistent, and when rotating to a special angle, the protruding height of the lever is smaller, so that the user operation is difficult, and the use experience of the user is reduced. SUMMARY

[0003] The utility model aims at least solve the prior art or related art in the prior fan up and down adjustment use experience lower technical problem.

[0004] Therefore, the embodiment of the utility model provides a cool and warm fan.

[0005] In order to realize the above-mentioned purpose, the embodiment of the utility model provides a cool and warm fan, which comprises a base structure, a air supply main body, a fan, a mounting port, an air outlet grille, an air supply adjustment mechanism, wherein the air supply main body is in transmission connection with the base structure, the fan is arranged in the air supply main body, the air supply main body can rotate relative to the base structure in the first direction, the mounting port is arranged on the air supply main body, and the mounting port is arranged opposite the air outlet of the fan, the air outlet grille is detachably connected with the mounting port, the air supply adjustment mechanism comprises a levering piece and an adjusting piece in transmission connection, the adjusting piece is arranged on the side of the air outlet grille facing the air supply main body, and the levering piece is in sliding connection with the air outlet grille, wherein the levering piece moves linearly relative to the air outlet grille, so that the adjusting piece can move relative to the air outlet grille in the second direction.

[0006] The cool and warm fan provided by the utility model mainly comprises a base structure and an air supply main body, the base structure provides a transmission interface, and the air supply main body is closely connected with the base structure through transmission connection, the air supply main body can rotate around the base in the first direction (for example, the horizontal direction), and specifically, the air supply main body can rotate around the axis, so that the air outlet direction of the fan is changed.

[0007] The fan is arranged in the air supply main body, air suction, acceleration and air supply are completed, of course, the transmission connection between the air supply main body and the base structure can be realized in the mode of bearing, gear transmission or other rotary linkage devices, so that the air supply main body can rotate relative to the base in the first direction.

[0008] By reserving a mounting port on the surface of the air supply main body at a position for connection with the air outlet grille, it is ensured that the air fan blows air out through the mounting port and the air outlet grille. The mounting port serves as an interface between the air outlet grille and the air supply main body, ensuring that the two are aligned in position, ensuring smooth air flow and improving overall air supply efficiency.

[0009] The air outlet grille is connected to the mounting port through detachable connection, so that the air outlet grille can be easily installed or removed, facilitating user replacement or cleaning. The air outlet grille serves as the first filtering and guiding device for air flowing out of the air fan, protecting the internal fan blades and preliminarily dispersing or concentrating the air flow.

[0010] Meanwhile, the air outlet grille is integrated with an adjustment member of the air supply adjustment mechanism, and the fixed position of the adjustment member determines the working reference of the adjustment mechanism. In the design, one side of the grille (facing the air supply main body) is reserved with space or assembly interface for fixing the adjustment member, so as to ensure that the adjustment mechanism can function in the predetermined direction.

[0011] The air supply adjustment mechanism mainly includes a dial member and an adjustment member, which together realize the function of adjusting the air flow of the air outlet grille. The dial member serves as a transmission element, responsible for accepting external control (such as manual dialing or motor driving) input and converting it into direct driving of the adjustment member. Its linear motion (within the preset motion trajectory) can accurately push the adjustment member to move in the second direction, achieving the purpose of adjusting the air flow outlet angle or position.

[0012] The dial member and the air outlet grille are connected through sliding connection to realize guided motion in fixed position. That is, there is a sliding groove or guide rail structure between the dial member and the grille, ensuring that the dial member can stably move in a straight line. At the same time, there is a transmission connection (which can be a mechanical connecting rod, buckle, gear transmission or other connection methods) between the dial member and the adjustment member, ensuring that the dial member can drive the adjustment member synchronously when moving.

[0013] The linear motion path of the dial member determines the moving direction (i.e. the second direction) of the adjustment member on the air outlet grille. The second direction is the up-down direction, which can improve the air outlet effect of the fan under the action of the air supply adjustment mechanism. Especially in the case of a warm air fan blowing hot air outward, the hot air itself has a small density and will naturally move upward. By using the air supply adjustment mechanism to swing in the second direction, which can be specifically up-down swing, the hot air can be blown downward, avoiding direct blowing of the hot air on the user's face and improving the heating effect.

[0014] The adjustment member directly participates in adjusting the air outlet state, and changes the shape, angle or position of the air outlet by being integrated on the air outlet grille or with the grille, so as to adjust the direction and distribution of air flow.

[0015] The adjusting member is connected with the knob through a transmission mechanism, so that the linear motion of the knob can drive the adjusting member to move in the preset second direction. Specifically, the adjusting member is installed on the air outlet grille, especially on the side close to the air supply body, so that the adjusting member can directly interfere with the air flow after passing through the installation opening and the grille when moving. The position of the adjusting member is closely related to the movement path of the knob, and the moving direction (second direction) is determined by the linear sliding of the knob, thereby forming the overall air direction adjustment function.

[0016] It should be emphasized that by limiting the linear motion of the knob, the adjustment of the air outlet direction can be realized, and the size of the knob does not change compared to the air outlet grille. No matter where the knob moves, the user can easily operate it, thereby improving the user experience.

[0017] In some technical solutions, optionally, a sliding groove is arranged on the air outlet grille, and the knob specifically comprises: a knob, which is arranged opposite to the sliding groove and is arranged on the side of the air outlet grille away from the air supply body; a sliding block, which is detachably connected with the knob and is arranged on the side of the air outlet grille facing the air supply body; wherein, when the knob and the sliding block are connected, the knob is stressed to drive the sliding block to slide along the sliding groove.

[0018] In this technical solution, a sliding groove is arranged on the air outlet grille, and the knob and the sliding block form a detachable connection. The sliding groove provides a movement guide rail for the knob, so that the knob can smoothly slide in a specific direction (i.e. the second direction).

[0019] The knob is arranged on the side of the air outlet grille away from the air supply body, i.e. the outer side of the fan, which is convenient for the user to directly operate. The knob is arranged opposite to the sliding block and is detachably connected through buckles, screws or other means. As a control component directly operated by the user, the knob is moved along the sliding groove by the user applying an external force (pushing or pulling). Through the connection with the sliding block, the displacement of the knob is converted into the movement of the sliding block, so that the adjusting mechanism can accurately adjust the air direction.

[0020] Since the knob is on the outer side, the force is usually pushed and pulled (along the sliding groove), which can avoid affecting the internal air duct or causing structural interference.

[0021] The sliding block is arranged on the side of the air outlet grille facing the air supply body, i.e. the inside of the grille, which directly affects the air direction adjusting mechanism and forms a detachable connection with the knob. This design is convenient for later maintenance, replacement or upgrading of the adjusting mechanism. Under the stress of the knob, the sliding block slides along the sliding groove, thereby driving the adjusting member or the swing leaf to adjust the air supply angle.

[0022] After being driven by the knob, the sliding block slides along the sliding groove, thereby driving the connected swing leaf or adjusting member to change the air direction.

[0023] In some embodiments, the air outlet grille and / or the air outlet of the fan are provided with a plurality of first shaft holes, and the adjusting member comprises: a plurality of swing leaf members arranged at intervals along a second direction, one end of each swing leaf member is provided with a guide vane, the other end of each swing leaf member is provided with a first shaft and a second shaft arranged at intervals, the second shaft is arranged on the side of the first shaft away from the guide vane, and the first shaft is detachably connected with the first shaft hole; and a connecting rod mechanism extending along the second direction, the connecting rod mechanism is provided with a plurality of second shaft holes, each second shaft hole is detachably connected with the second shaft; wherein at least one of the plurality of swing leaf members is provided with a swing arm corresponding to the sliding block, and the knob is stressed to drive the sliding block and the swing arm to move.

[0024] In this technical solution, a plurality of first shaft holes are arranged on at least one of the air outlet grille and the air outlet, and the adjusting member comprises a swing leaf member and a connecting rod mechanism, the first shaft of each swing leaf member is connected with the air outlet grille through the first shaft hole, so that the swing leaf member can rotate in a stable track, thereby adjusting the air outlet angle.

[0025] The plurality of swing leaf members are arranged at intervals along a second direction, and each swing leaf member is provided with a guide vane. By adjusting the positions of the swing leaf members, the flow direction of the air can be changed, thereby adjusting the direction and angle of the air.

[0026] The first shaft and the second shaft of the swing leaf member are responsible for connecting and supporting the rotating structure of the swing leaf member, so that the swing leaf member can rotate around these shafts to adjust the air direction. The first shaft is detachably connected with the first shaft hole, allowing the swing leaf member to be disassembled or replaced when needed. The second shaft is connected with the second shaft hole of the connecting rod mechanism, ensuring that the connecting rod mechanism can transmit the adjusting force from the knob to the swing leaf member, achieving precise air direction adjustment.

[0027] By arranging a swing arm corresponding to the sliding block on at least one swing leaf member, the swing arm moves together with the sliding block when the knob is actuated.

[0028] Each swing leaf member is connected with the first shaft hole through the first shaft, and the air direction can be changed within a set range during rotation. The second shaft is connected with the second shaft hole of the connecting rod mechanism, ensuring that all swing leaf members can move synchronously, thereby achieving uniform air flow adjustment.

[0029] In some embodiments, the end of the guide vane away from the first shaft is provided with a plurality of guide vane teeth, and a guide vane groove is formed between adjacent two guide vane teeth.

[0030] In this technical solution, the shape of the guide vane is limited, specifically, a plurality of guide vane teeth are arranged at intervals at the end of the guide vane away from the first shaft, and a groove structure, i.e., a guide vane groove, is formed between adjacent two guide vane teeth. During air outlet, the air flow can be guided more uniformly and stably.

[0031] The guide vane teeth play a role in guiding air flow and reducing turbulence, thereby improving the air flow efficiency and comfort of the fan. The guide vane groove controls the distribution and wind speed of the air flow by dividing the air flow into different areas, avoiding the phenomenon of excessive concentration or unevenness of the air flow. The guide vane groove can also make the fan more efficient by reducing the resistance of the air flow, thereby improving the air supply effect.

[0032] It can be understood that the air supply effect can be improved by designing the guide vane as teeth.

[0033] In some technical solutions, the air outlet grille includes a plurality of grille bars extending in the second direction, and the guide vane groove is arranged opposite to the grille bars of the air outlet grille, and each guide vane tooth is located between two adjacent grille bars.

[0034] In this technical solution, the air outlet grille includes a plurality of grille bars extending in the second direction, and the guide vane groove is arranged opposite to the grille bars of the air outlet grille, and each guide vane tooth is located between two adjacent grille bars. The air outlet grille includes a plurality of parallel grille bars, and the extension direction of each grille bar is the second direction. Under the action of the grille bars, the air flow can be preliminarily guided before entering the air passage, so that the air flow has a certain guidance.

[0035] The guide vane groove is arranged opposite to the grille bars of the air outlet grille, which ensures that the teeth of the guide vane, i.e. the guide vane teeth, maintain a suitable distance with the grille bars and have enough space for air distribution when the air flow passes through, avoiding excessive concentration or dispersion of the air flow.

[0036] Each guide vane tooth is located between two adjacent grille bars. This design not only ensures that the guide vane teeth can rotate freely without obstruction, but also avoids interference between the guide vane and the grille bars. Due to the support of the grille bars, the guide vane teeth can effectively guide the air flow without interfering with the air flow, while maintaining the uniformity and stability of the air flow.

[0037] In some technical solutions, the swing leaf member specifically includes at least one first swing leaf and at least one second swing leaf, and the first swing leaf is provided with a swing arm.

[0038] In this technical solution, the swing leaf member is divided into two types, specifically including a first swing leaf and a second swing leaf. The swing arm is arranged on the first swing leaf as the driving member in the entire swing leaf member. When the swing arm is moved by the sliding block, the first swing leaf will rotate, and the second swing leaf will also rotate under the linkage action of the connecting rod mechanism. It can be understood that the second swing leaf as an auxiliary swing leaf cooperates with the first swing leaf to help achieve wider wind direction adjustment and enhance the air supply range.

[0039] In some technical solutions, optionally, the second rotating shaft is provided with a connecting baffle at one end or both ends, and the connecting baffle is used to connect the first rotating shaft and the second rotating shaft, so as to ensure that the rotation of the swing leaf member can be smoothly and coordinately transmitted between the two shafts.

[0040] In this technical solution, the connecting baffle is arranged on one end or both ends of the second rotating shaft, and the connecting baffle is used to connect the first rotating shaft and the second rotating shaft, so as to ensure that the rotation of the swing leaf member can be smoothly and coordinately transmitted between the two shafts.

[0041] The swing arm can maintain stability during rotation through cooperation with the connecting baffle, the extension direction of the swing arm coincides with the extension direction of the connecting baffle, so that the swing leaf member can coordinately rotate in a certain track, and the stability of the overall structure is improved.

[0042] Since the connecting baffle connects the first rotating shaft and the second rotating shaft, the stable extension direction of the swing arm coincides with the extension direction of the baffle, so as to ensure that the swing leaf of the fan can rotate uniformly and stably. The movement track of the swing leaf is not easy to deviate, and performance fluctuations caused by asymmetric or unstable shaft center are avoided.

[0043] In some technical solutions, one end of the knob is provided with a clamping piece, and the slider specifically includes: a connecting table, the connecting table is provided with a clamping groove, the clamping piece is clamped with the clamping groove; a driving hole is arranged in the connecting table, one end of the swing arm extends into the driving hole; wherein the knob is stressed to drive the swing arm to move.

[0044] In this technical solution, one end of the knob is provided with a clamping piece, and the slider includes a connecting table, a clamping groove and a driving hole, and the clamping piece is clamped with the clamping groove. The knob is provided with a clamping piece, which can ensure that the knob is firmly connected to the slider during use, and the clamping relationship between the clamping piece and the clamping groove can effectively transmit torque when the knob is operated, and stably drive the slider to move.

[0045] Through the cooperation of the clamping groove and the clamping piece, the knob can be freely moved within the required range, and meanwhile, loosening or falling off of the knob during operation is avoided.

[0046] The connecting table in the slider is provided with a clamping groove, which is specially used to receive the clamping piece of the knob, so as to ensure that the knob does not fall off or get stuck during sliding. The connecting table is used to ensure that the knob is stably connected with the slider, and when force is applied, the slider can smoothly slide along the set track without deviation.

[0047] The slider is internally provided with a driving hole, and one end of the swing arm extends into the driving hole. Through this structure, the knob can drive the swing arm to move up and down or in other directions after being stressed.

[0048] The design of the driving hole enables the force of the knob to be effectively transmitted to the swing arm, and then the swing leaf is driven to rotate, so as to adjust the wind direction or the wind speed.

[0049] In some embodiments, the air outlet grille is curved, and the knob protrudes from a tangent plane corresponding to the sliding groove in a cross section of the air outlet grille.

[0050] In this embodiment, the air outlet grille is curved, and the curved design makes the air outlet grille more streamlined in appearance, enhancing the overall aesthetics of the fan.

[0051] The knob protrudes from the tangent plane corresponding to the sliding groove, so that the knob forms a visible protrusion on the air outlet grille, which is more intuitive for the user to operate.

[0052] In some embodiments, the air supply body is arranged on one side of the base structure along the second direction.

[0053] In this embodiment, the air supply body is arranged on one side of the base structure along the second direction, so that the air supply body and the base structure are arranged vertically.

DETAILED DESCRIPTION

[0066] In order to enable the above-mentioned objects, features and advantages of the embodiments of the present application to be more clearly understood, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0067] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, however, embodiments of the present application can be practiced without other different from the description herein, therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0068] The following description refers to the accompanying drawings, in which Figures 1 to 9 Some embodiments according to the present application are described.

[0069] As Figure 1 and Figure 2 The present embodiment provides a cooling and heating fan 100, mainly comprising a base structure 102 and a blowing main body 104, the base structure 102 provides a transmission interface, and the blowing main body 104 is closely connected with the base structure 104 through transmission connection, as Figure 7 The blowing main body 104 can rotate around the base in the first direction (for example, the horizontal direction), and specifically, the blowing main body 104 can rotate around its axis, changing the air outlet direction of the fan 1042.

[0070] The type of the cooling and heating fan 100 includes but is not limited to tower fan, cooling fan and heating fan.

[0071] Further, the base structure 102 is located at the lowermost part of the whole structure, and the inside can be provided with transmission mechanism or connecting pin, rotating shaft and other elements, to ensure that the rotating motion is stable and controllable.

[0072] The blowing main body 104 is internally provided with a fan 1042 to complete the air suction, acceleration and delivery. Of course, the transmission connection between the blowing main body 104 and the base structure 102 can be achieved by but not limited to bearing, gear transmission or other rotating linkage device, to ensure that the blowing main body 104 can rotate relative to the base in the set first direction.

[0073] Further, the blowing main body 104 internally has a motor, a transmission gear and other components in addition to the fan 1042, which together complete the rotating and blowing work.

[0074] By reserving a mounting port 106 on the surface of the blowing main body 104, the connection with the air outlet grille 108 is ensured, and the air outlet of the fan 1042 is ensured to be sent out through the mounting port 106 and the air outlet grille 108. The mounting port 106 serves as the interface between the air outlet grille 108 and the blowing main body 104, ensuring that the two are aligned in position, ensuring smooth air flow transmission and improving the overall blowing efficiency.

[0075] The air outlet grille 108 is connected with the mounting hole 106 through a detachable connection, so that the air outlet grille 108 can be easily mounted or dismounted, facilitating the user to replace or clean it. The air outlet grille 108 serves as the first filtering and guiding device through which the air flows out of the fan 1042, which not only protects the internal fan 1042 blades, but also preliminarily disperses or concentrates the air flow.

[0076] Meanwhile, the air outlet grille 108 is integrated with the adjusting member 114 of the air supply adjusting mechanism 110, and the fixed position of the adjusting member 114 determines the working reference of the adjusting mechanism. In the design, the side surface (facing the air supply main body 104) of the grille is reserved with space or assembly interface for fixing the adjusting member 114, so as to ensure that the adjusting mechanism can function in the predetermined direction.

[0077] The air supply adjusting mechanism 110 mainly includes the adjusting member 114 and the adjusting member 114 as shown in Figure 4 and Figure 6 , which together realize the function of adjusting the air flow of the air outlet grille 108. The specific adjusting direction is shown by the arrow in Figure 6 .

[0078] The adjusting member 112 serves as a transmission element, which is responsible for accepting the input of external control (such as manual adjustment or motor drive) and converting it into direct driving of the adjusting member 114. The linear motion (within the preset motion track) of the adjusting member 112 can accurately push the adjusting member 114 to move in the second direction as shown in Figure 7 , so as to adjust the air outlet angle or position of the air flow.

[0079] The adjusting member 112 and the air outlet grille 108 are connected through sliding connection to realize the guided motion of the fixed position. That is, there is a sliding groove or guide rail structure between the adjusting member 112 and the grille, which ensures that the adjusting member 112 can stably move along the straight line. At the same time, there is a transmission connection (which can be a mechanical connecting rod, buckle, gear transmission or other connection mode) between the adjusting member 112 and the adjusting member 114, which ensures that the adjusting member 114 can be driven synchronously when the adjusting member 112 moves.

[0080] The linear motion path of the adjusting member 112 determines the moving direction (i.e. the second direction) of the adjusting member 114 on the air outlet grille 108, which is usually opposite to the direction of the air supply main body 104 (for example, the side facing the air supply main body 104).

[0081] The adjusting member 114 directly participates in the adjustment of the air outlet state, and changes the shape, angle or position of the air outlet on the air outlet grille 108 or in the integrated manner with the grille, so as to adjust the direction and distribution of the air flow.

[0082] The adjustment member 114 is connected with the knob 112 through a transmission mechanism, ensuring that the linear motion of the knob 112 can drive the adjustment member 114 to move in a preset second direction. Specifically, the adjustment member 114 is installed on the air outlet grille 108, particularly on the side close to the air supply body 104, so that the adjustment member 114 can directly interfere with the air flow after passing through the installation opening 106 and the grille from the air blower 1042 when moving. The position of the adjustment member 114 is closely related to the movement path of the knob 112, and the moving direction (second direction) is determined by the linear sliding of the knob 112, thereby forming the overall air direction adjustment function.

[0083] It should be emphasized that by limiting the linear motion of the knob 112, the adjustment of the air outlet direction can be achieved, and the size of the knob 112 does not change compared to the air outlet grille 108. No matter where the knob 112 moves, the user can easily operate it, improving the user experience.

[0084] It should be noted that the air supply body 104 is connected with the base through a transmission connection, so that the air supply body 104 can rotate relative to the base in a predetermined direction (usually horizontal or in the horizontal plane), so that the air outlet direction of the air blower 1042 can be adjusted. Through the air supply adjustment mechanism 110 integrated on the air outlet grille 108 (including the knob 112 and the adjustment member 114), the displacement adjustment of the air outlet grille 108 in another direction (usually vertical or in the vertical plane) can be achieved. Specifically, the linear motion of the knob 112 on the grille will drive the adjustment member 114 connected therewith to move in the second direction, thereby changing the position and angle of the air outlet. This design makes the air flow direction more accurately oriented according to user needs, such as adjusting the air supply height or angle, so that the air flow distribution is more uniform and comfortable.

[0085] Combining the two adjustment methods, the entire fan realizes "three-dimensional" air supply when air supplying, that is, it can change the air direction by horizontal rotation, and can change the air flow direction by local adjustment on the grille.

[0086] In some embodiments, optionally, the air outlet grille 108 is provided with a sliding groove 1082, and the knob 112 includes a knob 1122 and a sliding block 1124, which are detachably connected. The sliding groove 1082 provides a movement guide rail for the knob 112, so that the knob 112 can smoothly slide in a specific direction (i.e. the second direction).

[0087] The knob 1122 is arranged on the side of the air outlet grille 108 away from the air supply body 104, that is, the outer side of the fan, which is convenient for the user to directly operate. The knob 1122 is arranged opposite to the sliding block 1124 and is detachably connected through buckles, screws or other means. The knob 1122 is directly operated by the user, and the user moves it along the sliding groove 1082 by applying an external force (pushing or pulling). Through the connection with the sliding block 1124, the displacement of the knob 1122 is converted into the movement of the sliding block 1124, so that the adjustment mechanism can accurately adjust the air direction.

[0088] Since the knob 1122 is on the outer side, the force is usually push-pull (along the sliding groove 1082), which can avoid affecting the internal air duct or causing structural interference.

[0089] The sliding block 1124 is arranged on the side of the air outlet grille 108 towards the air supply body 104, that is, the inside of the grille, which directly affects the air direction adjustment mechanism. The sliding block 1124 is detachably connected with the knob 1122, which is convenient for later maintenance, replacement or upgrading of the adjustment mechanism. Under the force of the knob 1122, the sliding block 1124 slides along the sliding groove 1082, thereby driving the adjustment piece 114 or the swing leaf to adjust the air supply angle.

[0090] After being driven by the knob 1122, the sliding block 1124 slides along the sliding groove 1082, thereby driving the connected swing leaf or adjustment piece 114 to change the air direction.

[0091] Further, the sliding block 1124 is usually made of low-friction material (such as engineering plastic or metal guide rail) to reduce sliding resistance and improve the operation feel. Further, the knob 1122 and the sliding block 1124 are connected through buckles, screws or magnetic attraction, so that they can be closely linked and at the same time be easily disassembled and maintained. Further, the sliding block 1124 can act on the adjustment piece 114 (such as the swing leaf) through a connecting rod or directly, thereby finally affecting the air flow direction.

[0092] Specifically, the user pushes or pulls the knob 1122, and the knob 1122 slides along the sliding groove 1082. The knob 1122 transmits the movement to the sliding block 1124, and the sliding block 1124 moves along the sliding groove 1082. The sliding block 1124 drives the adjustment piece 114 (such as the connected swing leaf or other air blocking machine 1042 structure) to change the air outlet direction or angle.

[0093] After the user releases the knob 1122, the sliding block 1124 remains in the new position in the sliding groove 1082, ensuring that the air direction remains at the adjusted angle.

[0094] In some embodiments, optionally, as Figure 1 、 Figure 2 and Figure 5As shown, a plurality of first shaft holes 1084 are provided on at least one of the air outlet grille 108 and the air outlet 122, and the adjusting member 114 includes swing leaf members 1142 and a linkage mechanism 1148. A first rotation shaft 1144 of each swing leaf member 1142 is connected to the air outlet grille 108 through the first shaft hole 1084, so that the swing leaf member 1142 can rotate in a stable track, thereby adjusting the air outlet angle.

[0095] In one embodiment, as shown in Figure 2 and Figure 5 , the first shaft hole 1084 is only provided on the air outlet grille 108.

[0096] In one embodiment, the first shaft hole 1084 is only provided on the air outlet 122 of the fan 1042.

[0097] In one embodiment, the first shaft hole 1084 is provided on both the air outlet grille 108 and the air outlet 122 of the fan 1042.

[0098] A plurality of swing leaf members 1142 are arranged along the second direction, and each swing leaf member 1142 is provided with a guide vane 116. By adjusting the positions of the swing leaf members 1142, the flow direction of the air can be changed, thereby adjusting the direction and angle of the air.

[0099] The first rotation shaft 1144 and the second rotation shaft 1146 of the swing leaf member 1142 are responsible for connecting and supporting the rotation structure of the swing leaf member 1142, so that the swing leaf member 1142 can rotate around these shafts to adjust the air direction. The first rotation shaft 1144 is detachably connected to the first shaft hole 1084, allowing the swing leaf member 1142 to be detached or replaced when needed. The second rotation shaft 1146 is connected to the second shaft hole 1150 of the linkage mechanism 1148, ensuring that the linkage mechanism 1148 can transmit the adjusting force from the actuating member 112 to the swing leaf member 1142, achieving accurate air direction adjustment.

[0100] The linkage mechanism 1148 is responsible for transmitting the force of the actuating member 112 to the swing leaf member 1142, so that when the actuating knob 1122 is actuated, the swing leaf can rotate along the second direction (i.e., the up-down direction) to adjust the air outlet angle. Through the plurality of second shaft holes 1150 of the linkage mechanism 1148, the rotation of each swing leaf member 1142 can be synchronized, thereby ensuring the uniformity and consistency of the air direction adjustment.

[0101] By providing a swing arm 1152 corresponding to the sliding block 1124 on at least one swing leaf member 1142, as shown in Figure 5 and Figure 8 , the swing arm 1152 moves with the sliding block 1124 when the actuating knob 1122 is actuated.

[0102] When the user rotates the knob 1122, the knob 1122 slides along the sliding groove 1082, and the sliding block 1124 connected thereto moves in the second direction (e.g., the vertical direction). During the sliding process, the sliding block 1124 is linked with the swing arm 1152 connected thereto, and the swing arm 1152 drives the first rotating shaft 1144 of the swing leaf member 1142 to rotate, thereby achieving adjustment of the wind direction.

[0103] Each swing leaf member 1142 is connected to the first shaft hole 1084 through the first rotating shaft 1144 and can change the wind direction within a set range during rotation. The second rotating shaft 1146 is connected to the second shaft hole 1150 of the connecting rod mechanism 1148, ensuring that all swing leaf members 1142 can move synchronously, thereby achieving uniform wind flow adjustment.

[0104] The plurality of second shaft holes 1150 in the connecting rod mechanism 1148 are connected to the second rotating shaft 1146 of the swing leaf member 1142, and the force generated by rotating the knob 1122 drives the connecting rod mechanism 1148 to move, thereby causing the plurality of swing leaf members 1142 to rotate together, achieving the effect of accurately adjusting the wind direction. This synchronous transmission design enables all swing leaf members 1142 to work cooperatively, ensuring the accuracy and uniformity of wind direction adjustment.

[0105] In some embodiments, the shape of the guide vane 116 is optionally limited, and specifically, a plurality of guide vane teeth 1162 are designed at the end of the guide vane 116 away from the first rotating shaft 1144, and a slot-shaped structure, i.e., a guide vane slot 1164, is formed between adjacent two guide vane teeth 1162. When air is discharged, the air flow can be guided to be more uniform and stable during the flow process.

[0106] The guide vane teeth 1162 play a role in guiding the air flow and reducing turbulence, thereby improving the air flow efficiency and comfort of the fan. The guide vane slot 1164 controls the distribution of air flow and wind speed by dividing the air flow into different areas, avoiding the phenomenon of excessive concentration or unevenness of air flow. The guide vane slot 1164 can also make the fan more efficient by reducing the resistance of air flow, thereby improving the air supply effect.

[0107] It can be understood that the air supply effect can be improved by designing the guide vane 116 in a toothed manner.

[0108] In some embodiments, the air outlet grille 108 optionally includes a plurality of grille bars 1086 extending in the second direction, and the guide vane slot 1164 is arranged opposite the grille bars 1086 of the air outlet grille 108, and each guide vane tooth 1162 is located between adjacent two grille bars 1086. The air outlet grille 108 includes a plurality of grille bars 1086 arranged in parallel, and the extension direction of each grille bar 1086 is the second direction. Under the action of the grille bars 1086, a preliminary guiding effect on the air flow is achieved, so that the air flow can have a certain guiding nature before entering the air passage.

[0109] The guide vane slot 1164 is arranged opposite to the grid bars 1086 of the air outlet grille 108, ensuring that the teeth of the guide vane 116, i.e. the guide vane teeth 1162, maintain a suitable distance from the grid bars 1086 and have sufficient space for air distribution when the air flow passes through, avoiding excessive concentration or dispersion of the air flow.

[0110] Each guide vane tooth 1162 is located between two adjacent grid bars 1086, which not only ensures that the guide vane teeth 1162 can rotate freely without obstruction, but also avoids interference between the guide vane 116 and the grid bars 1086. Due to the support of the grid bars 1086, the guide vane teeth 1162 can effectively guide the air flow without interfering with the air flow, while maintaining the uniformity and stability of the air flow.

[0111] In some embodiments, as shown in Figure 3 , Figure 5 and Figure 9 , the swing leaf member 1142 is divided into two types, specifically including a first swing leaf 1154 and a second swing leaf 1156, wherein the swing arm 1152 is arranged on the first swing leaf 1154 as the driving member in the entire swing leaf member 1142, and when the swing arm 1152 is moved by the slider 1124, the first swing leaf 1154 will rotate, and under the linkage action of the connecting rod mechanism 1148, the second swing leaf 1156 will also rotate. It can be understood that the second swing leaf 1156 as an auxiliary swing leaf cooperates with the first swing leaf 1154 to help achieve more extensive wind direction adjustment and enhance the air supply range.

[0112] When the user adjusts the knob 112 or the slider 1124, the swing arm 1152 drives the first swing leaf 1154 to rotate, thereby adjusting the air outlet angle. Through linkage with the second swing leaf 1156, the rotation of the first swing leaf 1154 also drives the second swing leaf 1156 to change the angle, achieving more flexible wind direction adjustment and ensuring the uniformity of the air flow.

[0113] In some embodiments, optionally, a connecting baffle 118 can be arranged on one or both ends of the second rotating shaft 1146, and the connecting baffle 118 connects the first rotating shaft 1144 and the second rotating shaft 1146, ensuring that the rotation of the swing leaf member 1142 can be smoothly and coordinately transmitted between the two shafts.

[0114] The swing arm 1152 can maintain stability during rotation through cooperation with the connecting baffle 118, and the extension direction of the swing arm 1152 coincides with the extension direction of the connecting baffle 118, so that the swing leaf member 1142 can coordinately rotate in a certain track, improving the stability of the overall structure.

[0115] Since the connecting baffle 118 connects the first rotating shaft 1144 and the second rotating shaft 1146, the stable extension direction of the swing arm 1152 is consistent with the extension direction of the baffle, ensuring that the swing leaf of the fan can rotate uniformly and stably. The swing leaf movement trajectory is not prone to deviation, avoiding performance fluctuations caused by asymmetric or unstable shafts.

[0116] In some embodiments, optionally, one end of the knob 1122 is provided with a clamping piece 1202, and the slider 1124 includes a connecting table 1204, a clamping groove 1206, and a driving hole 1208, and is clamped with the clamping groove 1206 through the clamping piece 1202. The knob 1122 is provided with the clamping piece 1202, which on the one hand ensures that the knob 1122 can be firmly connected to the slider 1124 during use, and on the other hand, the clamping relationship between the clamping piece 1202 and the clamping groove 1206 enables the knob 1122 to effectively transmit torque during operation, stably driving the slider 1124 to move.

[0117] Through the cooperation of the clamping groove 1206 and the clamping piece 1202, the knob 1122 can move freely within the required range, while avoiding loosening or falling off of the knob 1122 during operation.

[0118] The connecting table 1204 in the slider 1124 is provided with the clamping groove 1206, which is specially used to receive the clamping piece 1202 of the knob 1122, so as to ensure that the knob 1122 does not fall off or get stuck during sliding. The connecting table 1204 ensures that the knob 1122 is stably connected to the slider 1124, and when force is applied, the slider 1124 can smoothly slide along the set trajectory without deviation.

[0119] The slider 1124 is internally provided with the driving hole 1208, and one end of the swing arm 1152 extends into the driving hole 1208. Through this structure, the knob 1122 can drive the swing arm 1152 to move up and down or in other directions after being subjected to force.

[0120] The design of the driving hole 1208 enables the force of the knob 1122 to be effectively transmitted to the swing arm 1152, thereby driving the swing leaf to rotate and adjusting the wind direction or speed.

[0121] When the user operates the knob 1122, the knob 1122 is connected to the clamping groove 1206 of the slider 1124 through the clamping piece 1202, and the knob 1122 can drive the slider 1124 to slide along the sliding groove 1082 after being subjected to force. Due to the stability of clamping, the operation of the knob 1122 will not cause jamming or falling off. The driving hole 1208 in the slider 1124 is connected with the swing arm 1152, and when the slider 1124 slides along the preset trajectory, the driving hole 1208 drives the swing arm 1152 to move, thereby changing the position or angle of the swing leaf and realizing wind direction adjustment.

[0122] The knob 1122 can accurately transmit the user's operating force through the cooperation of the clamping piece 1202 and the slider 1124. When the knob 1122 is turned, the knob 1122 is directly driven to drive the slider 1124, and then drives the swing arm 1152 to move through the driving hole 1208, thereby adjusting the wind direction or the air outlet angle of the fan.

[0123] The design of the clamping piece 1202 and the clamping groove 1206 ensures the firm connection between the knob 1122 and the slider 1124, avoiding the loosening or instability problem that may occur during use. This design improves the reliability and smoothness of user operation. Through the driving hole 1208 to drive the swing arm 1152, the operation of the knob 1122 directly affects the movement of the swing leaf, making the adjustment of the wind direction more accurate.

[0124] In some embodiments, optionally, the air outlet grille 108 is curved, and the curved design makes the air outlet grille 108 more in line with the appearance of streamline, enhancing the overall beauty of the fan. At the same time, the curved shape also helps to increase the flow efficiency of air flow inside the fan, reduce air resistance, and improve the stability and transmission effect of air volume.

[0125] The knob 1122 protrudes from the tangent surface corresponding to the sliding groove 1082, so that the knob 1122 forms a visible protrusion on the air outlet grille 108, which helps the user to operate more intuitively. The user can easily touch the position of the knob 1122, increasing the convenience of operation. In particular, since the turning piece 112 moves linearly relative to the air outlet grille 108, the protruding knob 1122 design not only improves the accuracy of operation, but also makes it easier for the user to operate after adjusting to any position, reducing the possibility of misoperation.

[0126] On the basis of any of the above embodiments, optionally, the air supply body 104 is arranged on one side of the base structure 102 along the second direction, so that the air supply body 104 and the base structure 102 are arranged vertically. When the cold and warm fan 100 is used as a tower fan, a cold fan and a warm air machine 1042, it is more convenient to blow air. The base structure 102 directly drives the air supply body 104 to rotate in the first direction, and the center of gravity of the cold and warm fan 100 is relatively low, effectively reducing the risk of tipping caused by unstable design or uneven structure of the fan, and improving the use safety of the equipment.

[0127] In a specific embodiment, an up-down swing air adjusting system is provided, and the left-right direction can automatically swing air. By arranging two left-right swing air systems in the up-down direction, the two swing air systems can be independently controlled, the blowing frequency experienced by the user is doubled, and the cooling and blowing effect is greatly improved.

[0128] The swing leaf is arranged at the air outlet grille 108 of the machine, and the up-down swinging of the dial can realize the up-down swinging of the swing leaf, so as to adjust the height and angle of the up-down air outlet, the left-right shaking assembly is installed at the bottom of the machine, and the up-down air outlet can realize the left-right swinging air supply, and finally realizes the three-dimensional air supply up-down and left-right.

The up-down dial is installed on the outer side of the air outlet grille 108, the dial can slide up and down along the air outlet grille 108, the sliding block 1124 is installed on the inner side of the air outlet grille 108, the buckle (i.e. the clamping part 1202) of the dial passes through the sliding groove 1082 and is buckled with the buckle table (i.e. the connecting table 1204) on the sliding block 1124, so as to complete the buckling installation. After connection, the dial assembly can slide up and down in the sliding groove 1082.
