[0047] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0048] Air treatment equipment, such as air purifiers and air humidifiers, generally have fans to drive the whole machine to supply air. The impeller of the fan is generally fixed and can only blow air in one direction, which is not effective in some scenarios. Take an air humidifier as an example. When used in a living room or bedroom, it is necessary to avoid blowing air towards people and furniture as much as possible. When in a plant maintenance area, the air needs to be blown towards the vegetation to provide good humidity for the vegetation.

[0049] Existing air handling equipment cannot meet the demand for adjustable air outlet direction. In view of this, the utility model provides a fan and air handling equipment, in which the fan blades are driven to rotate radially around the mounting tube by slidingly cooperating with the adjustment component and the sliding guide part, and the air outlet angle of the fan is adjusted, so that the fan can be used in different scenarios, thereby improving user satisfaction.

[0050] Reference below Figures 1 to 8A fan 1 according to a first aspect of an embodiment of the utility model is described. The fan 1 may include a mounting tube 11 , fan blades 12 , an adjustment assembly 13 and a main driving member 14 .

[0051] The mounting tube 11 may be cylindrical, and the inner side of the mounting tube 11 defines a mounting space 111. There are multiple blades 12, and multiple means two or more. Multiple blades 12 are arranged on the peripheral wall of the mounting tube 11 along the circumference of the mounting tube 1. For example, the blades 12 may be 3, 5 or 7, and the blades 12 are arranged at equal intervals around the axis of the mounting tube 11. Of course, the blades 12 may also be other numbers, and this embodiment does not limit this.

[0052] The adjustment component 13 is arranged in the installation space 111, and the fan blades 12 are in transmission cooperation with the adjustment component 13. A sliding guide portion 112 is provided on the installation tube 11, and at least part of the structure of the adjustment component 13 is in sliding cooperation with the sliding guide portion 112. For example, the sliding guide portion 112 can be provided on the peripheral wall of the installation tube 11, or on the end wall (such as the top wall or the bottom wall), and the sliding guide portion 112 can be a groove structure, a hole structure or other structure suitable for guiding the sliding of the adjustment component 13. When the adjustment component 13 moves along the sliding guide portion 112, it drives the fan blades 12 to rotate radially around the installation tube 11 (the direction of rotation is as shown in FIG. 1 ). Figure 6 As shown), the angle of the airflow driving portion 121 of the fan blade 12 is adjusted relative to the reference plane, and the reference plane can be perpendicular to the axial direction of the mounting tube 11, thereby adjusting the air outlet direction of the fan 1.

[0053] During the sliding cooperation between the adjusting component 13 and the sliding guide part 112, the sliding guide part 112 guides the adjusting component 13. For example, the sliding guide part 112 may be a guide groove, and the sliding cooperation with the adjusting component 13 may be that the adjusting component 13 is arranged in the guide groove, and when sliding along the guide groove, the adjusting component 13 drives the fan blades 12 to rotate radially around the mounting tube 11; of course, part of the structure of the adjusting component 13 may extend into the guide groove, slide along the guide groove, drive the fan blades 12 to rotate radially around the mounting tube 11, and adjust the air outlet direction of the fan 1.

[0054] In other embodiments, the sliding guide portion 112 may also be a guide column, and the adjustment component 13 may be slidably mounted on the guide column, and may also drive the fan blades 12 to rotate radially around the mounting tube 11 to adjust the air outlet direction of the fan 1.

[0055] The main driving member 14 is connected to the mounting tube 11 by transmission, and is used to provide power for the mounting tube 11, driving the mounting tube 11 to drive the fan blades 12 to rotate around the axial direction of the mounting tube 11, that is, the main driving member 14 can drive the mounting tube 11 and the fan blades 12 to rotate to generate wind force. The main driving member 14 may include a driving motor, and the driving motor and the mounting tube 11 are connected by transmission, which may be a gear drive, a belt drive, or a chain drive. For example, in the present embodiment, the driving motor may have a driving shaft 141, and the mounting tube 11 has an end with an opening 114 facing the driving motor, and is coaxially arranged on the driving shaft 141 of the driving motor, with a simple structure and easy installation. Start the driving motor to drive the mounting tube 11 and the fan blades 12 to rotate together, and the fan blades 12 are rotated to achieve wind discharge.

[0056] In the fan 1 of this embodiment, the user can slide the adjustment component 13 along the sliding guide portion 112 to drive the fan blades 12 to rotate radially around the mounting tube 11 to adjust the air outlet direction of the fan 1. This allows the user to flexibly adjust the air outlet direction of the fan 1 according to the usage requirements in different usage scenarios, thereby improving the user experience and thus improving the user satisfaction.

[0057] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 In some embodiments, the adjustment assembly 13 may include an active member 131 and a driven member 132. The active member 131 is rotatably disposed in the installation space 111. An operating handle 1311 is disposed on the active member 131. The operating handle 1311 is passed through the sliding guide portion 112 and slides along the sliding guide portion 112. The driven member 132 is connected to the fan blade 12. The active member 131 and the driven member 132 are in transmission cooperation. The user can slide the operating handle 1311 along the sliding guide portion 112 by toggling the operating handle 1311. At this time, the operating handle 1311 drives the active member 131 to rotate. The active member 131 drives the driven member 132 and the fan blade 12 to rotate around the radial direction of the installation tube 11 through transmission cooperation, thereby changing the angle of the fan blade 12 and thus changing the air outlet direction of the fan 1, so that the overall structure is relatively simple, easy to operate, and easy to implement.

[0058] The transmission cooperation may be belt transmission between the active member 131 and the driven member 132, direct contact between the active member 131 and the driven member 132, friction transmission, or gear transmission between the active member 131 and the driven member 132, which is not limited in this embodiment.

[0059] refer to Figure 5 and Figure 6According to some embodiments of the present invention, one end of the mounting tube 11 (eg, the bottom end of the mounting tube 11 ) has an opening 114 , and the sliding guide portion 112 is disposed at an end of the mounting tube 11 opposite to the opening 114 .

[0060] The active member 131 may be a cylindrical structure with both ends open, and the central axis of the active member 131 may be colinear with the central axis of the mounting tube 11. The operating handle 1311 is provided at one end of the active member 131 facing the sliding guide portion 112 (e.g., the top of the active member 131), and the end of the active member 131 facing away from the operating handle 1311 (e.g., the bottom of the active member 131) is provided with transmission teeth 1312 distributed along the circumferential direction, that is, the active member 131 is constructed as an annular rack structure. The driven members 132 are all located on the side of the active member 131 facing away from the operating handle 1311, and the driven members 132 are provided with matching teeth 1321 matching with the transmission teeth 1312, and the transmission teeth 1312 are meshed with the matching teeth 1321.

[0061] In this embodiment, the active member 131 and the driven member 132 are driven by gear meshing transmission. The operating handle 1311 slides along the sliding guide portion 112 to drive the active member 131 to rotate. The transmission member is driven to rotate through the meshing transmission of the transmission teeth 1312 and the matching teeth 1321. The structure is simple and reliable, easy to assemble, and highly practical.

[0062] refer to Figure 1 and Figure 5 Furthermore, since the active member 131 rotates when cooperating with the driven member 132, the sliding guide portion 112 can extend circumferentially along the mounting tube 11. For example, the sliding guide portion 112 can be constructed as an arc-shaped guide groove, and the center of the arc-shaped guide groove is located on the axis of rotation of the active member 131, so that when the user moves the operating handle 1311 to slide in the sliding guide portion 112, the active member 131 rotates synchronously, thereby improving the stability of the structure and the smoothness of the movement.

[0063] refer to Figure 4 Furthermore, the inner wall of the mounting tube 11 and the outer wall of the active component 131 are clearance-matched, so that the inner wall of the mounting tube 11 and the outer wall of the active component 131 do not contact each other. In the process of adjusting the air outlet direction of the fan 1, the wear between the inner wall of the mounting tube 11 and the outer wall of the active component 131 is reduced, which is beneficial to prolonging the service life of the equipment and helps to improve the smoothness of the operation of the active component 131.

[0064] refer to Figure 3 , Figure 4 and Figure 6According to some embodiments of the present invention, one of the active member 131 and the mounting tube 11 has a mounting structure, and the other has a first matching structure that matches the mounting structure. For example, the mounting structure can be provided on the active member 131, and the first matching structure can be provided on the mounting tube 11, or the mounting structure can be provided on the mounting tube 11, and the first matching structure can be provided on the active member 131.

[0065] The mounting structure can cooperate with the first matching structure so that the active component 131 is installed in the mounting space 111 of the mounting tube 11, thereby preventing the active component 131 from being disconnected from the mounting tube 11 and causing a rotational collision between the active component 131 and the mounting tube 11 when the main driving component 14 drives the mounting tube 11 to drive the fan blades 12 to rotate, thereby preventing damage to the fan 1.

[0066] Continue to refer Figure 3 , Figure 4 and Figure 6 Further, the mounting structure can be arranged on the mounting tube 11, and the mounting structure may include a limit platform 115, which is located on the inner wall of the mounting tube 11 at one end opposite to the opening 114 (for example, the top wall of the mounting tube 11), and the limit platform 115 includes a first section 1151 and a second section 1152, the first section 1151 extends axially along the mounting tube 11, and the second section 1152 extends radially outward along the first section 1151, and the first matching structure includes a mounting ring 1313, the mounting ring 1313 is located on the inner wall of the active part 131, the mounting ring 1313 is located between the first section 1151 and the second section 1152, and the mounting ring 1313 is supported on the second section 1152.

[0067] The mounting ring 1313 is formed on the inner wall of the active member 131 to protrude radially toward the mounting tube 11, and the second section 1152 of the limiting platform 115 is opposite to the inner wall of the mounting tube 11 facing the active member 131, forming a step groove, and the mounting ring 1313 is located in the step groove, and the second section 1152 supports the mounting ring 1313 on the side facing the mounting ring 1313. In this way, through the limiting cooperation between the mounting ring 1313 and the limiting platform 115, the degree of freedom of the active member 131 in the axial direction of the mounting tube 11 is limited, so that the active member 131 can only rotate under the action of the operating handle 1311, and the structure is simple, which is conducive to improving the stability and reliability of the structure.

[0068] Of course, the present application is not limited to this. The mounting structure can also be formed as an annular groove located on the inner circumferential wall of the mounting cylinder. The outer circumferential wall of the active component can be provided with a mounting protrusion protruding radially outward. The mounting protrusion can be multiple and arranged along the circumference of the active component 131. The mounting protrusion is provided in the annular groove and moves along the annular groove, thereby realizing the installation, fixation and rotation of the active component 131.

[0069] like Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments, the fan blade 12 may include an airflow driving part 121 and a connecting shaft 122. The side wall of the mounting cylinder 11 is provided with a plurality of mounting holes 113 arranged at intervals along the circumferential direction. The number of the mounting holes 113 matches the number of the fan blades 12. The connecting shaft 122 is passed through the mounting hole 113. The connecting shaft 122 is rotatable relative to the mounting cylinder 11 in the radial direction of the mounting cylinder 11, and the end of the connecting shaft 122 away from the airflow driving part 121 extends into the mounting space 111 and is connected to the follower 132. The airflow driving part 121 and the connecting shaft 122 are fixedly connected and are located at the end of the connecting shaft 122 away from the mounting space 111. The airflow driving part 21 serves as the airflow driving main structure of the fan blade 12, and drives the airflow to flow when it rotates with the mounting cylinder 11.

[0070] When the air outlet direction of the fan 1 needs to be adjusted, the user adjusts the operating handle 1311 to move along the sliding guide part 112 to drive the active part 131 to rotate. The active part 131 drives the driven part 132, the connecting shaft 122 and the airflow driving part 121 to rotate together around the radial direction of the mounting tube 11 through the meshing transmission of the transmission teeth 1312 and the matching teeth 1321, thereby adjusting the angle of the airflow driving part 121. The overall structure is relatively simple and easy to operate.

[0071] refer to Figure 5 and Figure 6 Furthermore, a sleeve 1131 is provided in the mounting hole 113, and when the connecting shaft 122 passes through the mounting hole 113, the sleeve 1131 is sleeved outside the connecting shaft 122. By providing the sleeve 1131, direct contact between the connecting shaft 122 and the mounting hole 113 is avoided, and when adjusting the air outlet direction, the connecting shaft 122 rotates and the sleeve 1131 can rotate synchronously, with low friction, which is beneficial to extending the service life of the fan 1.

[0072] refer to Figure 2 , Figure 4 and Figure 6 According to some embodiments of the utility model, the follower 132 is sleeved on the connecting shaft 122, and one end of the connecting shaft 122 extending into the installation space 111 defines an assembly hole. The adjustment assembly 13 may also include a fastener 133, which is arranged in the assembly hole to connect the follower 132 and the connecting shaft 122. For example, the fastener 133 may be a screw, a pin, a self-tapping screw, etc. The fastener 133 may have a fastening end, the outer diameter of the fastening end exceeds the outer diameter of the connecting shaft 122, and abuts against the side of the follower 132 away from the airflow driving part 121, so that the follower 132 will not fall off from the connecting shaft 122, thereby improving the stability of the structure.

[0073] refer to Figure 2Furthermore, the adjustment assembly 13 also includes a limit member 134, which is disposed at one end of the connecting shaft 122 facing the installation space 111, and the follower 132 defines a key slot, and the limit member 134 is located in the key slot.

[0074] The follower 132 and the connecting shaft 122 are connected by the fastener 133, which limits the axial movement of the follower 132 relative to the connecting shaft 122. However, relative rotation may occur between the follower 132 and the connecting shaft 122, resulting in the fan 1 being subjected to centrifugal force when the fan blades 12 rotate around the axis of the mounting tube 11 along with the mounting tube 11 during normal operation of the fan 1, causing the fan blades 12 to rotate radially around the mounting tube 11, resulting in poor air outlet effect. The connection between the connecting shaft 122 and the follower 132 is further fixed by the stopper 134, limiting the relative rotation between the connecting shaft 122 and the follower 132, thereby improving the stability of the structure.

[0075] The limiting member 134 may be a limiting rib, which is located at one end of the connecting shaft 122 facing the installation space 111 and protrudes toward the follower 132. The limiting rib is disposed in the keyway to limit the relative rotation between the follower 132 and the connecting shaft 122. Of course, in other embodiments of the present application, the limiting member 134 may also be a connecting key, which may include a flat key, a semicircular key, a wedge-shaped key, etc. A first keyway is provided at one end of the connecting shaft 122 facing the installation space 111, and the follower 132 defines a second keyway. The connecting key is partially located in the first keyway and the second keyway, respectively, to connect the follower 132 and the connecting shaft 122, thereby limiting the relative rotation between the follower 132 and the connecting shaft 122 and improving the stability of the structure.

[0076] refer to Figure 7 and Figure 8 In some embodiments, the fan 1 may further include a locking structure, which is configured to limit the operating handle 1311. When the fan 1 is operating normally, the locking structure locks the position of the operating handle 1311 to prevent the air outlet direction of the fan 1 from changing when the air is being discharged normally.

[0077] The driving shaft 141 of the driving motor extends through the side of the mounting tube 11 opposite to the opening 114, and a fixing cap 15 is provided on the protruding end of the driving shaft 141. The fixing cap 15 is threadedly connected to the driving shaft 141 and abuts against the outer wall of the side opposite to the opening 114 of the mounting tube 11, so that the mounting tube 11 and the driving shaft 141 of the driving motor are fixedly connected. In order to prevent the relative rotation between the mounting tube 11 and the driving shaft 141, a special-shaped hole can be provided on the inner wall of the mounting tube 11 away from the opening 114, and a block that cooperates with the special-shaped hole is provided on the driving shaft 141. The special-shaped hole and the block are limitedly matched to prevent the relative rotation between the mounting tube 11 and the driving shaft 141.

[0078] The locking structure is arranged on the fixing cap 15, and the locking structure may include a connecting section 151 and a pressure plate 152. The connecting section 151 is located on the outside of the fixing cap 15, the first end of the connecting section 151 is connected to the fixing cap 15, and the second end extends in a direction away from the opening 114 of the mounting tube 11, and the diameter gradually increases. The pressure plate 152 is connected to the second end of the connecting section 151 and extends radially outward of the mounting tube 11. The pressure plate 152 abuts against the operating handle 1311 on the side of the mounting tube 11.

[0079] The locking structure is used to limit the position of the operating handle 1311. After the user adjusts the operating handle 1311 to slide along the sliding guide portion 112 to change the air outlet direction of the fan 1, if the operating handle 1311 is not limited, when the fan 1 is operating normally and air is discharged, the operating handle 1311 may slide along the sliding guide portion 112 due to the centrifugal force, causing the air outlet direction to change, affecting the user experience.

[0080] After unscrewing the fixing cap 15, the user moves the operating handle 1311 along the sliding guide part 112 to adjust the air outlet angle. After the air outlet angle is adjusted, the position of the operating handle 1311 is determined, and the user tightens the fixing cap 15, and the pressure plate 152 abuts against the operating handle 1311. At this time, the mounting ring 1313 on the active part 131 abuts against the second section 1152 of the limit platform 115, and the operating handle 1311 is locked by static friction, so as to prevent the position of the operating handle 1311 from changing when the driving motor drives the mounting cylinder 11 and the fan blades 12 to rotate to discharge air, thereby improving the stability of the structure.

[0081] The working principle of the fan 1 in the first aspect of the embodiment of the utility model is:

[0082] When the air outlet direction of the fan 1 needs to be adjusted, the operating handle 1311 is moved to slide along the sliding guide part 112, and the active part 131 rotates relative to the mounting tube 11. The transmission teeth 1312 are engaged with the meshing teeth to drive the driven part 132 and the connecting shaft 122 to rotate synchronously, and the airflow driving part 121 of the fan blade 12 rotates radially around the mounting tube 11 to change the air outlet direction of the fan blade 12.
