Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and particularly relates to a humidifying fan. Background Art

[0002] A humidifying fan can increase the air humidity in a room while adjusting the temperature and reduce air dust. It usually includes a water tank, an atomization module and a mist outlet. Among them, the atomization module can atomize the water in the water tank and diffuse it into the whole room through the mist outlet.

[0003] In the related art, the mist outlet is generally arranged on the head or the base of the humidifying fan. However, when the mist outlet is arranged on the base of the humidifying fan, due to the low height of the mist outlet, the mist will concentrate at the base of the humidifying fan, unable to effectively increase the air humidity, with poor humidifying uniformity, and the mist outlet is easily contaminated. When the mist outlet is arranged at the head of the humidifying fan, it will increase the cost of the humidifying fan and it is difficult to ensure the sealing between the parts in the head. Summary of the Utility Model

[0004] In view of this, the utility model provides a humidifying fan to solve the problems that when the mist outlet of the humidifying fan in the related art is arranged on the base, it cannot effectively increase the air humidity, has poor humidifying uniformity and the mist outlet is easily contaminated, and the problems that when the mist outlet of the humidifying fan is arranged on the head, the cost of the humidifying fan is high and it is difficult to ensure the sealing between the parts in the head.

[0005] The utility model provides a humidifying fan, including:

[0006] A base;

[0007] A rod assembly arranged on the base, and a fan head is arranged at one end of the rod assembly far from the base;

[0008] An atomization module arranged on the base or the rod assembly for atomizing water. An air outlet and an air outlet channel are arranged on the rod assembly. The air outlet channel is connected between the air outlet end of the atomization module and the air outlet. The air outlet is used for releasing water mist.

[0009] Advantageous Effects: The mist outlet of the humidifying fan in the embodiment of the utility model is arranged in the rod assembly. During the use of the humidifying fan, the water mist generated by the atomization module can flow into the rod through the mist outlet channel and be discharged outward through the mist outlet arranged on the rod. The wind blown by the fan head can carry the mist blown out from the mist outlet and diffuse to a farther place, thereby improving the humidifying uniformity of the humidifying fan. The humidifying fan in the embodiment of the present application has good humidifying uniformity.

[0010] Moreover, since the humidifying fan according to the embodiment of the present application has the mist outlet provided on the rod assembly, the height of the mist outlet is relatively high and it is not easy to accumulate dust. This ensures that the mist blown out from the mist outlet can effectively increase the air humidity, and the mist outlet is not easily contaminated. In addition, the structure of the rod assembly itself is relatively simple, and it is easy to set up the mist passage. Setting the mist outlet on the rod assembly can effectively reduce the cost of the humidifying fan and is not easy to damage the sealing between parts.

[0011] Therefore, the humidifying fan according to the embodiment of the present utility model can ensure that the humidifying fan can effectively increase the air humidity, has good humidifying uniformity, while avoiding the mist outlet being contaminated, and can effectively reduce the cost of the humidifying fan and is not easy to damage the sealing between the parts of the humidifying fan.

[0012] In an optional implementation manner, the rod assembly includes:

[0013] An inner tube, one end of which is connected to the mist outlet end of the atomizing module, and the other end forms a mist outlet. The mist passage is formed inside the inner tube;

[0014] An outer tube, sleeved outside the inner tube. An avoidance opening is provided at a position on the outer tube corresponding to the mist outlet, and the fan head is connected to the outer tube.

[0015] Beneficial effects: By setting it in this way, the outer tube can be used to support the fan head, and the inner tube can be used to guide the water mist prepared by the humidifying module to guide the water mist to be discharged through the mist outlet. At the same time, the water mist prepared by the humidifying module is separated from the internal structure of the fan head, thereby improving the sealing between the various components of the humidifying fan.

[0016] In an optional implementation manner, the outer tube can move along the axis of the outer tube. The inner tube includes:

[0017] A lower tube, the lower end of which is connected to the mist outlet end of the atomizing module;

[0018] A movable tube, coaxially arranged with the lower tube, capable of sliding along the axial direction of the lower tube. The lower tube and the movable tube are hermetically connected through a first sealing ring, and the mist outlet is provided on the movable tube.

[0019] Beneficial effects: By setting it in this way, the operator can drive the outer tube to slide relative to the inner tube, thereby adjusting the blowing height of the humidifying fan. When the outer tube moves relative to the inner tube, the movable tube can move synchronously with the outer tube, and then adjust the height of the mist outlet, thereby synchronously adjusting the mist outlet height of the humidifying fan. The first sealing ring is clamped between the lower tube and the movable tube, which can prevent the water mist from leaking through the gap between the lower tube and the movable tube.

[0020] In an optional implementation manner, the movable tube includes:

[0021] A movable tube body, inserted into the lower tube;

[0022] The mist outlet head is connected to the movable tube. The mist outlet head includes a connecting section and a mist outlet section that are connected in sequence. The connecting section is used to connect to the main body of the movable tube. The mist outlet section is arranged at an angle with the connecting section and is at least partially inserted into the avoidance opening. The mist outlet is formed on the mist outlet section.

[0023] Advantageous effects: By setting it in this way, during the assembly process of the inner tube and the outer tube in the embodiment of the present utility model, the main body of the movable tube can be first assembled in the lower tube, then the outer tube is sleeved on the lower tube, and the mist outlet head can be sleeved on the main body of the telescopic tube from the upper end of the outer tube until the mist outlet is matched with the avoidance opening in the outer tube, thereby completing the assembly of the upper tube.

[0024] In an optional implementation manner, a guiding structure is provided between the movable tube and the lower tube. The guiding structure extends along the axial direction of the lower tube, and the movable tube is slidably connected to the lower tube through the guiding structure.

[0025] Advantageous effects: By setting it in this way, the guiding structure can guide the movable tube to prevent the movable tube from deflecting relative to the lower tube during movement and ensure that at least a part of the end of the movable tube provided with the mist outlet is located in the avoidance opening.

[0026] In an optional implementation manner, the mist outlet head is inserted into the main body of the movable tube. One of the mist outlet head and the main body of the movable tube is formed with an anti-misalignment convex portion, and the other of the mist outlet head and the main body of the movable tube is formed with an anti-misalignment groove for accommodating the anti-misalignment convex portion.

[0027] Advantageous effects: By setting it in this way, the anti-misalignment convex portion can be matched with the anti-misalignment groove to prevent the mist outlet head from moving relative to the main body of the movable tube.

[0028] In an optional implementation manner, a first stop convex portion is provided on the outer periphery of the movable tube, and a second stop convex portion that can abut against the first stop convex portion is provided at the top of the lower tube.

[0029] Advantageous effects: By setting it in this way, when the outer tube moves to the highest position, the first stop convex portion can abut against the second stop convex portion, thereby preventing the movable tube from continuing to rise and coming out of the lower tube.

[0030] In an optional implementation manner, a third stop convex portion is provided on the outer periphery of the lower tube, and the third stop convex portion can abut against the bottom end of the outer tube.

[0031] Advantageous effects: When the outer tube descends to the lowest position, the bottom end of the outer tube can abut against the third stop convex portion, avoiding the outer tube descending beyond the lifting stroke and causing a failure.

[0032] In an alternative embodiment, the humidifying fan further includes a locking assembly, which has a locked state and an unlocked state. When the locking assembly is in the unlocked state, the outer tube can move along the axis of the lower tube. When the locking assembly is in the locked state, the outer tube can be limited on the lower tube.

[0033] Advantageous effects: With such a setting, the operator can drive the outer tube to move relative to the lower tube when the locking assembly is in the unlocked state. When the outer tube moves to a suitable position, the operator can switch the locking assembly to the locked state, thereby switching the outer tube to a suitable position.

[0034] In an alternative embodiment, the bottom end of the outer tube is provided with an external thread, and the locking assembly includes:

[0035] A locking collar sleeve, which is used to sleeve outside the inner tube. An internal thread is formed on the inner circumference of the locking collar sleeve, and the internal thread is used for threaded connection with the external thread;

[0036] An abutting wall, which is connected to the bottom of the locking collar sleeve and is arranged between the inner circle of the internal thread and the inner tube. An abutting surface is formed between the abutting wall and the outer tube. When the outer tube is threadedly connected to the abutting wall, the abutting wall can abut against the inner tube under the action of the abutting surface.

[0037] Advantageous effects: With such a setting, when the outer tube is moved to a suitable height, the operator can screw the locking collar sleeve tightly at the lower end of the outer tube. During the screwing process, the lower end of the outer tube can enter between the abutting wall and the locking collar sleeve. The lower end of the outer tube cannot be deformed under the constraint of the locking collar sleeve, and the abutting wall is pressed through the abutting surface, so that the abutting wall deforms inward and presses the lower tube, thereby locking the outer tube on the lower tube to achieve the purpose of fixing the height of the outer tube.

[0038] In an alternative embodiment, the abutting surface includes:

[0039] A first abutting surface, which is formed on the abutting wall and slopes away from the axis of the inner tube from top to bottom;

[0040] A second abutting surface, which is formed on the outer tube and slopes away from the axis of the inner tube from top to bottom, and the slope of the second abutting surface is greater than the slope of the first abutting surface.

[0041] Advantageous effects: With such a setting, during the process of the operator screwing the locking collar sleeve tightly on the outer tube, since the slope of the second abutting surface is greater than the slope of the first abutting surface, when the two come into contact, the second abutting surface can squeeze the first abutting surface so that the first abutting surface deforms.

[0042] In an alternative embodiment, the base includes:

[0043] The fog collection cover is arranged at the fog outlet end of the atomization module and is used to collect the water mist generated by the atomization module.

[0044] Beneficial effects: The fog collection cover can cooperate with the fog collection hopper to collect the water mist prepared by the atomization module into the fog outlet channel, so as to improve the sealing performance of the structure.

[0045] In an optional embodiment, the fog collection cover and the fog collection hopper are hermetically connected through a second sealing ring.

[0046] Beneficial effects: The second sealing ring can improve the sealing performance between the fog collection cover and the fog collection hopper, thus avoiding water mist leakage between the fog collection cover and the fog collection hopper.

[0047] In an optional embodiment, the base further includes:

[0048] A bottom cover, on which the atomization module and the fog collection cover are arranged;

[0096] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0097] The following combines Figures 1 to 28 , and describes the embodiments of the present utility model.

[0098] According to an embodiment of the present utility model, on the one hand, a humidifying fan is provided, which includes a base 1, a rod body assembly 2 and an atomization module 3. Among them, the rod body assembly 2 is arranged on the base 1, and a fan head 4 is arranged at one end of the rod body assembly 2 away from the base 1. The atomization module 3 is arranged on the base 1 or the rod body assembly 2 and is used for atomizing water. A mist outlet 2011 and a mist outlet channel are arranged on the rod body assembly 2, and the mist outlet channel is connected between the mist outlet end of the atomization module 3 and the mist outlet 2011, and the mist outlet 2011 is used for releasing water mist.

[0099] The fog outlet 2011 of the humidifying fan according to the embodiment of the present utility model is arranged inside the rod body assembly 2. During the use of the humidifying fan, the water mist generated by the atomization module 3 can flow into the rod body through the fog outlet channel and be discharged outward through the fog outlet 2011 provided on the rod body. The wind blown by the fan head 4 can carry the fog blown out from the fog outlet 2011 and spread to a farther place, thereby improving the uniformity of humidification of the humidifying fan. The humidifying fan according to the embodiment of the present application has good humidifying uniformity.

[0100] Moreover, since the fog outlet 2011 of the humidifying fan according to the embodiment of the present application is arranged on the rod body assembly 2, the height of the fog outlet 2011 is relatively high and it is not easy to accumulate dust, ensuring that the fog blown out from the fog outlet 2011 can effectively increase the air humidity, and the fog outlet 2011 is not easily polluted. In addition, the structure of the rod body assembly 2 itself is relatively simple, and it is easy to set up the fog outlet channel. Arranging the fog outlet 2011 on the rod body assembly 2 can effectively reduce the cost of the humidifying fan and is not easy to damage the sealing performance between parts.

[0101] Therefore, the humidifying fan according to the embodiment of the present utility model can effectively increase the air humidity while ensuring good humidifying uniformity, avoid pollution of the fog outlet 2011, and can effectively reduce the cost of the humidifying fan and is not easy to damage the sealing performance between the parts of the humidifying fan.

[0102] In one embodiment, as Figure 23 shown, the base 1 further includes a water tank 106, a rotation source 105 and a wind wheel 104. The atomization module 3 can prepare the water in the water tank 106 into water mist. The rotation source 105 can drive the wind wheel 104 to rotate, so that the air flow carries the water mist to rise and is discharged outward through the fog outlet channel and the fog outlet 2011 in sequence.

[0103] In an optional embodiment, a floating member 107 and a monitoring module are further arranged in the base 1. Among them, the floating member 107 is located in the water tank 106 and can float up and down with the change of the water level in the water tank 106. The monitoring module can detect the floating member 107 when the floating member 107 reaches a preset height, thereby monitoring whether the water tank 106 is short of water or full, and then reminding the user to stop or start replenishing water into the water tank 106.

[0104] In one embodiment, universal wheels 108 are further arranged at the bottom of the base 1. The universal wheels 108 can facilitate the operator to move the humidifying fan, so as to move the humidifying fan to a suitable position.

[0105] In one embodiment, as Figure 2As shown in the figure, the rod assembly 2 includes an inner tube 201 and an outer tube 202. One end of the inner tube 201 is connected to the mist outlet end of the atomization module 3, and the other end forms a mist outlet 2011. A mist outlet passage is formed inside the inner tube 201. The outer tube 202 is sleeved outside the inner tube 201. An avoidance opening 2021 is provided at a position on the outer tube 202 corresponding to the mist outlet 2011, and the fan head 4 is connected to the outer tube 202.

[0106] By setting it like this, the outer tube 202 can be used to support the fan head 4, and the inner tube 201 can be used to guide the water mist prepared by the humidification module to guide the water mist to be discharged through the mist outlet 2011. At the same time, the water mist prepared by the humidification module is separated from the internal structure of the fan head 4, thereby improving the sealing performance between the various components of the humidifying fan.

[0107] As an alternative embodiment, the rod assembly 2 is an integral structure. The upper end of the rod assembly 2 is connected to the fan head 4, and the inner peripheral wall of the rod assembly 2 encloses a diversion channel.

[0108] In one embodiment, as shown in Figure 20 and Figure 21 the figure shows that the outer tube 202 can move along the axis of the outer tube 202. The inner tube 201 includes a lower tube 2012 and a movable tube 2013. One end of the lower tube 2012 is connected to the mist outlet end of the atomization module 3. The movable tube 2013 is coaxially arranged with the lower tube 2012 and can slide axially along the lower tube 2012. The lower tube 2012 and the movable tube 2013 are hermetically connected through a first sealing ring 204, and the mist outlet 2011 is provided on the movable tube 2013.

[0109] By setting it like this, the operator can drive the outer tube 202 to slide relative to the inner tube 201, thereby adjusting the air outlet height of the humidifying fan. When the outer tube 202 moves relative to the inner tube 201, the movable tube 2013 can move synchronously with the outer tube 202, and then adjust the height of the mist outlet 2011, thereby synchronously adjusting the mist outlet height of the humidifying fan. The first sealing ring 204 is clamped between the lower tube 2012 and the movable tube 2013, and can prevent the water mist from leaking through the gap between the lower tube 2012 and the movable tube 2013.

[0110] The number of the first sealing rings 204 can be selected as one or more. In a preferred embodiment, there are multiple first sealing rings 204, which are arranged at intervals along the axial direction of the movable tube 2013. Circumferential grooves are formed on the movable tube 2013 and / or the lower tube 2012, and the circumferential grooves are used to limit the first sealing rings 204.

[0111] As an alternative embodiment, as shown in Figure 22 and Figure 23As shown, the outer tube 202 can also be fixedly arranged on the base 1, and the inner tube 201 is an integral structure. To facilitate the alignment of the mist outlet 2011 of the inner tube 201 with the avoidance opening 2021 of the outer tube 202, an elastic member 206 is preferably provided between the inner tube 201 and the outer tube 202. During the assembly process of the rod body assembly 2, the outer tube 202 can be sleeved on the inner tube 201 and compress the elastic member 206. When the outer tube 202 moves to a position where the avoidance opening 2021 is aligned with the mist outlet 2011 on the inner tube 201, the elastic member 206 can drive the inner tube 201 to move towards the direction close to the avoidance opening 2021 through its own elastic restoring force, and at least part of the end of the inner tube 201 provided with the mist outlet 2011 is inserted into the avoidance opening 2021.

[0112] As a preferred embodiment, as Figure 24 and Figure 27 shown, a clamping portion 20124 is provided on the surface of the inner tube 201 on the side away from the mist outlet 2011. The clamping interior is used to be clamped with the elastic member 206, and the elastic member 206 can be limited to the side of the clamping portion 20124 away from the mist outlet 2011, ensuring that the elastic member 206 can press the inner tube 201 towards the avoidance opening 2021, so that at least part of the end of the inner tube 201 provided with the mist outlet 2011 is inserted into the avoidance opening 2021.

[0113] In one embodiment, as Figure 28 shown, the movable tube 2013 includes a movable tube main body 20131 and a mist outlet head 20132. Among them, the movable tube main body 20131 is inserted into the lower tube 2012. The mist outlet head 20132 is connected to the movable tube 2013. The mist outlet head 20132 includes a connecting section and a mist outlet section connected in sequence. The connecting section is used to be connected to the movable tube main body 20131. The mist outlet section is arranged at an angle with the connecting section and at least part of it passes through the avoidance opening 2021, and the mist outlet 2011 is formed on the mist outlet section.

[0114] By setting like this, during the assembly process of the inner tube 201 of the embodiment of the present utility model with the outer tube 202, the movable tube main body 20131 can be first assembled in the lower tube 2012, and then the outer tube 202 is sleeved on the lower tube 2012. The mist outlet head 20132 can be sleeved on the telescopic tube main body from the upper end of the outer tube 202 until the mist outlet 2011 cooperates with the avoidance opening 2021 in the outer tube 202, thereby completing the assembly of the upper tube.

[0115] In one embodiment, a guiding structure 205 is provided between the movable tube 2013 and the lower tube 2012. The guiding structure 205 extends along the axial direction of the lower tube 2012, and the movable tube 2013 is slidably connected to the lower tube 2012 through the guiding structure 205.

[0116] By setting it like this, the guiding structure 205 can guide the movable tube 2013 to avoid deflection of the movable tube 2013 relative to the lower tube 2012 during movement, and ensure that at least a part of the end of the movable tube 2013 provided with the mist outlet 2011 is located within the avoidance opening 2021.

[0117] Among them, the guiding structure 205 can be optionally configured to include a guiding groove 2052 formed on one of the movable tube 2013 and the lower tube 2012, and a guiding convex part 2051 formed on the other of the movable tube 2013 and the lower tube 2012. The guiding convex part 2051 is arranged in the guiding groove 2052 and can move relative to the guiding groove 2052.

[0118] As a transformable embodiment, the guiding structure 205 can also be optionally a guiding slide rail.

[0119] In one embodiment, the mist outlet head 20132 is inserted into the movable tube main body 20131. An anti-misalignment convex part 20135 is formed on one of the mist outlet head 20132 and the movable tube main body 20131, and an anti-misalignment groove 20134 for accommodating the anti-misalignment convex part 20135 is formed on the other of the mist outlet head 20132 and the movable tube main body 20131.

[0120] By setting it like this, the anti-misalignment convex part 20135 can cooperate with the anti-misalignment groove 20134 to avoid movement of the mist outlet head 20132 relative to the movable tube main body 20131.

[0121] As a transformable embodiment, the mist outlet head 20132 can also be optionally sleeved on the outer periphery of the movable tube main body 20131.

[0122] The mist outlet head 20132 is preferably but not limited to being connected to the movable tube 2013 by means of snap-fastening, ultrasonic welding or bonding, etc., so as to form a non-leaking whole.

[0123] In one embodiment, as Figure 9 shown, a first stop convex part 20133 is provided on the outer periphery of the movable tube 2013, and a second stop convex part 20121 capable of abutting against the first stop convex part 20133 is provided on the top of the lower tube 2012.

[0124] By setting it like this, as Figure 21 shown, when the outer tube 202 moves to the highest position, the first stop convex part 20133 can abut against the second stop convex part 20121, thereby preventing the movable tube 2013 from continuing to rise and being disengaged from the lower tube 2012.

[0125] A third stop convex part 20122 is provided on the outer periphery of the lower tube 2012, and the third stop convex part 20122 can abut against the bottom end of the outer tube 202.

[0126] As Figure 20 shown, when the outer tube 202 descends to the lowest position, the bottom end of the outer tube 202 can abut against the third stop projection 20122, preventing the outer tube 202 from descending beyond the lifting stroke and causing a malfunction.

[0127] In one embodiment, as Figure 3 shown, the humidifying fan further includes a locking assembly 203. The locking assembly 203 has a locked state and an unlocked state. When the locking assembly 203 is in the unlocked state, the outer tube 202 can move along the axis of the lower tube 2012. When the locking assembly 203 is in the locked state, the outer tube 202 can be limited on the lower tube 2012.

[0128] With such a setting, the operator can drive the outer tube 202 to move relative to the lower tube 2012 when the locking assembly 203 is in the unlocked state. When the outer tube 202 moves to a suitable position, the operator can switch the locking assembly 203 to the locked state, thereby switching the outer tube 202 to a suitable position.

[0129] In one embodiment, as Figure 4 , Figure 5 , Figure 13 and Figure 14 shown, the bottom end of the outer tube 202 is provided with an external thread. The locking assembly 203 includes a locking collar 2031 and an abutting wall 2032. Among them, the locking collar 2031 is used to sleeved outside the inner tube 201. An internal thread is formed on the inner circumference of the locking collar 2031, and the internal thread is used for threaded connection with the external thread. The abutting wall 2032 is connected to the bottom of the locking collar 2031 and is disposed between the inner circle of the internal thread and the inner tube 201. An abutting surface 2033 is formed between the abutting wall 2032 and the outer tube 202. When the outer tube 202 is threadedly connected to the abutting wall 2032, the abutting wall 2032 can abut against the inner tube 201 under the action of the abutting surface 2033.

[0130] With such a setting, when the outer tube 202 is moved to a suitable height, the operator can screw the locking collar 2031 tightly at the lower end of the outer tube 202. During the screwing process, the lower end of the outer tube 202 can enter between the abutting wall 2032 and the locking collar 2031. The lower end of the outer tube 202 cannot be deformed under the constraint of the locking collar 2031, and presses against the abutting wall 2032 through the abutting surface 2033, so that the abutting wall 2032 deforms inward and presses against the lower tube 2012, thereby locking the outer tube 202 on the lower tube 2012 to achieve the purpose of fixing the height of the outer tube 202.

[0131] In one embodiment, the abutting surface 2033 includes a first abutting surface 20331 and a second abutting surface 20332. Among them, the first abutting surface 20331 is formed on the abutting wall 2032 and slopes away from the axis of the inner tube 201 from top to bottom. The second abutting surface 20332 is formed on the outer tube 202 and slopes away from the axis of the inner tube 201 from top to bottom, and the slope of the second abutting surface 20332 is greater than that of the first abutting surface 20331.

[0132] By setting it in this way, during the process of the operator screwing the locking ring sleeve 2031 onto the outer tube 202, since the slope of the second abutting surface 20332 is greater than that of the first abutting surface 20331, when the two come into contact, the second abutting surface 20332 can squeeze the first abutting surface 20331, causing the first abutting surface 20331 to deform.

[0133] As a transformable embodiment, the abutting surface 2033 is formed on one of the outer tube 202 and the locking ring sleeve 2031, and an annular boss is provided on the other of the outer tube 202 and the locking ring sleeve 2031. The annular boss can abut against the abutting surface 2033, causing the abutting wall 2032 to deform inward.

[0134] In a preferred embodiment, a plurality of deformation notches are provided on the abutting wall 2032. The plurality of deformation notches are arranged at intervals along the circumferential direction of the abutting wall 2032, facilitating the inward deformation of the abutting wall 2032.

[0135] In one embodiment, as Figure 15 and Figure 16 shown, the base 1 includes a fog collection cover 101. The fog collection cover 101 covers the fog outlet end of the atomization module 3 and is used to collect the water mist generated by the atomization module 3. An outlet is provided on the fog collection cover 101; a fog collection hopper 20123 is formed at the bottom of the rod assembly 2, and the fog collection hopper 20123 covers the outlet of the fog collection cover 101.

[0136] The fog collection cover 101 can cooperate with the fog collection hopper 20123 to collect the water mist prepared by the atomization module 3 into the fog outlet channel, improving the sealing performance of the structure.

[0137] In one embodiment, as Figure 17 shown, the fog collection cover 101 and the fog collection hopper 20123 are hermetically connected through a second sealing ring 5.

[0138] Among them, the second sealing ring 5 can improve the sealing performance between the fog collection cover 101 and the fog collection hopper 20123, thus avoiding water mist leakage between the fog collection cover 101 and the fog collection hopper 20123.

[0139] In one embodiment, asFigure 18 and Figure 19 As shown in Figure 19 , the base 1 further includes a bottom cover 102 and an upper base cover 103. Among them, the atomization module 3 and the fog collection cover 101 are arranged on the bottom cover 102. The upper base cover 103 is detachably connected to the bottom cover 102. An installation through hole 1031 is provided on the upper base cover 103. The installation through hole 1031 is sleeved on the rod body assembly 2. The upper base cover 103 is connected to the fog outlet 2011 through a fastener.

[0140] The upper base cover 103 can cover the components such as the atomization module 3 and the fog collection cover 101, and at the same time be connected to the rod body assembly 2 to reliably limit the rod body assembly 2 on the base 1.

[0141] Among them, the fastener is preferably but not limited to a bolt or a rivet.

[0142] As a transformable embodiment, when the rod body assembly 2 cannot be telescoped, the upper base cover 103 can be optionally integrally connected to the bottom end of the outer tube 202. During the assembly process, the fog collection hopper 20123 of the lower tube 2012 can be prevented from being above the fog collection cover 101. The upper tube can be sleeved on the outer periphery of the lower tube 2012 and connected to the lower tube 2012 through the upper base cover 103, so as to fix the lower tube 2012 on the upper base cover 103.

[0143] In one embodiment, the fog outlet 2011 is arranged at one end of the rod body assembly 2 close to the fan head 4.

[0144] As a transformable embodiment, the fog outlet pipe is communicated with the air duct of the fan head 4 to drive the water mist to diffuse outward by means of the wind blown by the fan head 4.

[0145] Next, the installation method of the humidifying fan according to the embodiment of the present invention will be described:

[0146] First, install the second sealing ring 5 in the limit groove 1011 of the fog collection cover 101, and install the first sealing ring 204 at the lower end of the movable tube body 20131. Then, assemble the movable tube 2013 with the first sealing ring 204 installed in the lower tube 2012, and make the chute on the movable tube 2013 sleeved on the installation convex part on the lower tube 2012.

[0147] Then, pass the lower tube 2012 through the installation through hole 1031 of the upper base cover 103, fix and connect the upper base cover 103 and the lower tube 2012 through a fastener, and then place the assembled upper base cover 103 and the lower tube 2012 above the fog collection cover 101.

[0148] Next, sleeved the locking assembly 203 on the upper end face of the movable tube 2013, sleeved the outer tube 202 on the movable tube 2013, and threadedly connect the locking assembly 203 and the outer tube 202 to complete the installation.

[0149] In summary, the humidifying fan of the embodiment of the present utility model can effectively increase the air humidity while ensuring good humidifying uniformity, avoid the fog outlet 2011 from being contaminated, effectively reduce the cost of the humidifying fan, and is not easy to damage the sealing performance between the parts of the humidifying fan.

[0150] Although the embodiments of the present utility model have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present utility model, and such modifications and variations fall within the scope defined by the appended claims.
