Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology, and in particular relates to a folding fan humidifier. Background Technology

[0002] Common desktop personal humidifiers typically spray water mist upwards to provide a humid microclimate. However, these humidifiers have low power and a limited mist diffusion range, requiring the user to be very close to them for effective humidification. Beyond approximately 30 centimeters, the humidity level does not show significant improvement.

[0003] To increase the humidity range, a fan can be combined with a humidifier to create a mist fan. The fan's airflow propels the water mist further, achieving the dual effects of humidification and cooling. Currently, small desktop mist fans for personal use blow out the water mist produced by the atomizer in a humidifier, achieving both cooling and humidification. The atomizer in this type of mist fan is located at the fan's outlet (the positive pressure section, also the air vent). Since the water mist produced by the atomizer consists of droplets of varying diameters, smaller droplets are blown further by the fan and gradually evaporate, while larger droplets settle on the desktop near the mist fan. Over time, this can lead to condensation, a phenomenon particularly noticeable in high-humidity environments.

[0004] Therefore, there is an urgent need for a fan humidifier that can solve the above-mentioned water accumulation problem and provide users with a better experience; in addition, the fan humidifier can be designed with a foldable structure for easy carrying and travel.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0009] A fan assembly, movably connected to the humidifier assembly, includes a duct and a drain channel;

[0010] The air duct is arranged around the fan assembly and is configured to guide the liquid that splashes onto the inner wall of the air duct and collects to the drain tank.

[0011] The drainage channel is located at the connection point between the fan assembly and the humidifier assembly, and is connected to the humidifier assembly.

[0012] Furthermore, the humidifier assembly includes:

[0013] The main body contains an electrically connected power supply, power adapter, and circuit board for controlling the operation of the humidifier components.

[0014] The water tank is connected to the machine body;

[0015] Atomizing plate holder is arranged on the outer edge of the machine body or water tank and communicates with the water tank;

[0016] The atomizing plate, which is attached to the bottom surface of the atomizing plate holder, is configured to convert the liquid into a mist and spray it out to the outside.

[0017] The fan assembly is hinged to the humidifier assembly at a position away from the atomizing plate mounting base via a hinge; the drain groove is formed above the hinge.

[0019] Furthermore, the water tank is equipped with a docking port.

[0020] Furthermore, the bottom surface of the atomizing plate holder is an inclined surface that slopes towards the hinge direction, with an angle A between it and the vertical direction; the value of A is in the range of 0° < A < 90°.

[0021] Furthermore, the humidifier assembly also includes an absorbent cotton swab; the absorbent cotton swab is installed at the lower end of the atomizing plate, with its upper end face fitting against the lower end face of the atomizing plate, and its lower end extending into the water tank to connect the atomizing plate fixing seat to the water tank, and its upper end face being made into an inclined surface shape parallel to the bottom surface of the atomizing plate fixing seat.

[0022] Furthermore, the fan assembly includes:

[0023] The fan motor mounting part is installed inside the air duct at one end of the fan inlet, away from the atomizing plate fixing seat. The hinge is installed thereon, and the drain groove is formed above the hinge.

[0024] A fan and a motor that drives the fan; the fan and motor are mounted in the fan-motor mounting section;

[0025] An air guide grid is installed inside the air guide duct at one end of the fan outlet.

[0026] Furthermore, the air guide grid has a cross-sectional shape that is trapezoidal, triangular, or wedge-shaped with an outer width greater than the inner width.

The liquid mist sprayed by the humidifier can be drawn in through the air inlet and blown out through the air outlet. During this process, small droplets are blown out with the wind to humidify and cool the user, while large droplets are thrown to the outside by centrifugal force and will not be blown onto the face or tabletop, thereby improving the user's comfort.

[0031] 2. By installing a guide duct around the fan, large droplets thrown out can be collected into a liquid flow, which then flows along the inner wall of the guide duct and through the drain groove to the humidifier assembly at the bottom, thus solving the problem of water accumulation and drainage.

[0032] 3. The fan assembly is movably connected to the upper part of the humidifier assembly, which allows the fan assembly to be folded into the humidifier assembly, thereby reducing the overall size of the device and making it easy to carry and travel. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] Please refer to Figures 1 to 7 To better understand the specific structure of this utility model. Figure 1 As shown, a folding fan 204 humidifier includes:

[0047] Humidifier assembly 1 is used to convert liquid into liquid mist and spray it to the outside.

[0048] The fan assembly 2 is movably connected to the humidifier assembly 1 and includes a guide duct 201 and a drain trough 202.

[0049] The air duct 201 is arranged around the fan assembly 2 and is configured to guide the liquid that is splashed onto the inner wall of the air duct 201 and collected to the drain trough 202.

[0050] The drainage channel 202 is located at the connection point between the fan assembly 2 and the humidifier assembly 1, and is connected to the humidifier assembly 1.

[0051] It should be noted that the guide duct 201 is preferably cylindrical, and the inner wall can be made into a textured form, which makes it easier to guide the liquid to the drain trough 202 below.

[0052] It should be noted that water can be added to the humidifier component 1 as the humidifying liquid, or water with additives (such as essential oils) can be used as the humidifying liquid; there are no restrictions here.

[0053] In specific implementation, this utility model installs the fan assembly 2 on the upper part or side upper part of the humidifier assembly 1, that is, the humidifier is located at the air inlet of the fan 204. The liquid mist sprayed by the humidifier can be drawn in through the air inlet and blown out through the air outlet. During this process, small droplets are blown out with the wind to humidify and cool the user, while large droplets are thrown to the outside by centrifugal force and will not be blown onto the face or table, thereby improving the user's comfort. A guide duct 201 is set around the fan 204 to collect the large droplets into a liquid flow, which is then gathered along the inner wall of the guide duct 201 and guided through the drain trough 202 to the humidifier assembly 1 at the lower end, thereby solving the problem of water accumulation. The fan assembly 2 is movably connected to the upper part of the humidifier assembly 1, which can be folded towards the humidifier assembly 1 to reduce the overall size of the device and make it easy to carry.

[0054] In the embodiments provided by this utility model, such as Figure 2 As shown, the humidifier assembly 1 includes:

[0055] The main body 101 houses a power supply, a power adapter, and a circuit board that are electrically connected to each other, for controlling the operation of the humidifier assembly 1.

[0056] Water tank 102 is connected to the body 101;

[0057] The atomizing plate fixing seat 103 is arranged on the outer edge of the body 101 or the water tank 102 and is connected to the water tank 102;

[0058] The atomizing plate 104 is attached to the bottom surface of the atomizing plate holder 103 and is configured to convert the liquid into a mist and spray it out to the outside.

[0059] The fan assembly 2 is hinged to the humidifier assembly 1 at a position away from the atomizing plate fixing seat 103 via a hinge 105; the drain groove 202 is formed above the hinge 105.

[0060] The humidifier assembly 1 also includes a water collection tank (not shown in the figure); the water collection tank is arranged on the side of the body 101 and is configured to collect the liquid guided by the drain trough 202; the fan assembly 2 is hinged to the side wall of the water collection tank away from the atomizing plate fixing seat 103 via a hinge 105; the lower end of the drain trough 202 is connected to the water collection tank.

[0061] The water tank 102 is equipped with a connection port (not shown in the figure).

[0062] It should be noted that the unit 101 contains components such as a power adapter and a circuit board. The internal structure of the unit 101 is the same as that of the humidifier unit 101 in the prior art, and no limitation is made here.

[0063] It should be noted that the connection position between the body 101 and the water tank 102 can be set such that the body 101 is at the bottom of the humidifier assembly 1 (not shown in the figure), and the water tank 102 is arranged at the top of the body 101 (not shown in the figure). With this arrangement, the water tank 102 can also include a top cover, which can be fastened when the water tank 102 is used to supply water to prevent liquid from overflowing. The connector can be set at the bottom of the water tank 102 and can be connected to the mouth of a common mineral water bottle through a thread, that is, the mineral water bottle can replace the water tank 102 to supply water.

[0064] It should be noted that the atomizing plate fixing seat 103 can be arranged on the side wall of the body 101 or water tank 102 near the fan assembly 2. The recessed hole opened on the side wall of the body 101 or water tank 102 is arranged at the edge of the body 101 or water tank 102 to avoid the middle of the fan motor mounting part 203 mentioned later, so that the liquid mist can smoothly enter the air inlet of the fan 204; the liquid in the water tank 102 or the connected mineral water bottle can supply liquid for the atomizing plate 104.

[0065] It should be noted that the atomizing plate holder 103 faces the water pool, so that excess liquid or larger droplets after atomization can be directly discharged into the water pool.

[0066] It should be noted that the atomizing plate 104 is preferably a high-frequency oscillating plate commonly used in the prior art, but other structural forms can also be used, and there are no restrictions here.

[0067] It should be noted that the water pool is arranged side by side with the main body 101, and the fan assembly 2 is hinged to the side wall of the water pool via the hinge 105 (not shown in the figure), and is arranged in a position away from the main body 101, so that the liquid mist sprayed by the atomizing plate 104 can enter from the air inlet of the fan assembly 2 and be blown out from the air outlet.

[0068] It should be noted that the fan assembly 2 is connected to the water tank via the hinge 105. The angle with the horizontal plane can be manually adjusted with the hinge 105 as the center. When not in use, the fan assembly 2 can be folded into the water tank, thereby reducing the overall size and making it easy to carry.

[0069] It should be noted that the hinge 105 is preferably a rotary locking pin hinge 105 with preload, so that the fan assembly 2 can stay at the required angle when rotating around the hinge 105 using the preload.

[0070] It should be noted that the liquid that flows along the inner wall of the guide duct 201 to the lower hinge 105 can flow back to the water collection tank through the drain trough 202; after a period of use, the water in the water collection tank needs to be emptied.

[0071] It should be noted that the drainage channel 202 can be made by making a hole above the hinge 105.

[0072] In practice, with the above structure, users can either pour liquid directly into the water tank 102 or connect a mineral water bottle to the connector. Both methods can supply liquid to the atomizing plate 104, providing users with more options. The structure of the humidifier component 1 can smoothly convert liquid into liquid mist and spray it to the outside, providing support for achieving the humidification effect required by the user. In addition, since the water tank 102 is located at the top, there is no need to set up a water-absorbing cotton swab 106 to supply liquid to the atomizing plate 104, thus simplifying the structure.

[0073] In the embodiments provided by this utility model, such as Figures 2-4 As shown, the humidifier assembly 1 can also be arranged in another way, that is, the body 101 is arranged at the upper part of the humidifier assembly 1, and the water tank 102 is arranged at the lower part of the body 101.

[0074] The atomizing plate holder 103 is provided on the upper end face of the body 101 and is arranged near the edge of the body 101;

[0075] A water return hole 107 is provided on the side wall of the atomizing plate fixing seat 103; the water return hole 107 is connected to the water tank 102;

[0076] The atomizing plate 104 is attached to the bottom surface of the atomizing plate fixing seat 103;

[0077] The humidifier assembly 1 also includes a water-absorbing cotton swab 106; the water-absorbing cotton swab 106 is installed at the lower end of the atomizing plate 104, the upper end face is in contact with the lower end face of the atomizing plate 104, the lower end extends into the water tank 102 to connect the atomizing plate fixing seat 103 with the water tank 102, and the upper end face is made into an inclined surface shape parallel to the bottom surface of the atomizing plate fixing seat 103;

[0078] The fan assembly 2 is hinged to the side wall of the body 101 away from the atomizing plate 104 via a hinge 105; the hinge 105 has a drainage groove 202 above it; the drainage groove 202 is connected to the water tank 102.

[0079] It should be noted that in the humidifier assembly 1 with this structure, the atomizing plate fixing seat 103 is a recessed hole opened at the upper end of the body 101. The purpose of placing it at the edge of the body 101 is to avoid the middle of the fan motor mounting part 203 mentioned later, so that the liquid mist can smoothly enter the air inlet of the fan 204.

[0080] It should be noted that the atomizing plate holder 103 can also serve as a liquid collection pool for the atomizing plate 104, preventing excess liquid from overflowing, and the liquid can return to the water tank 102 through the return water hole 107.

[0081] It should be noted that the absorbent cotton swab 106 is preferably made of a material with good water absorption, such as high-density sponge, which can draw the liquid in the water tank 102 to the atomizing plate 104 for atomization by using siphon effect.

[0082] It should be noted that the fan assembly 2 is hinged to the body 101 via the hinge 105 and is arranged above the body 101, so that the liquid mist sprayed by the atomizing plate 104 can enter from the air inlet of the fan assembly 2 and be blown out from the air outlet.

[0083] It should be noted that the fan assembly 2 is connected to the body 101 via the hinge 105. The angle with the horizontal plane can be manually adjusted with the hinge 105 as the center. When not in use, the fan assembly 2 can be folded onto the body 101, thereby reducing the overall size and making it easy to carry.

[0084] It should be noted that the drainage channel 202 can be made by making a hole above the hinge 105.

[0085] In practice, the structure of humidifier component 1 can smoothly convert liquid into liquid mist and spray it to the outside, providing support for achieving the humidification effect required by the user.

[0086] In one implementation, such as Figure 4 As shown, the bottom surface of the atomizing plate fixing seat 103 is an inclined surface that is inclined towards the hinge 105, and the angle between it and the vertical direction is A; the value of A is 0° < A < 90°.

[0087] It should be noted that, regardless of the arrangement of the humidifier assembly 1, the bottom surface of the atomizing plate holder 103 is always set as an inclined surface with an angle A.

[0088] It should be noted that, since the fan assembly 2 can be manually adjusted around the hinge 105 to the angle with the horizontal plane, the adjustment angle can be controlled by the hinge 105 (the hinge 105 adopts a structure with controllable angle); in this utility model, a corresponding relationship is set between the adjustment angle of the fan assembly 2 and the bottom tilt angle A of the atomizing plate fixing seat 103: when A is set to 0°~30°, in order to draw more liquid mist into the fan assembly 2, it is preferable to control the adjustable angle range of the fan assembly 2 between 0°~90°; when A is set to 30°~45°, it is preferable to control the adjustable angle range of the fan assembly 2 between 0°~60°; when A is set to 45°~60°, it is preferable to control the adjustable angle range of the fan assembly 2 between 0°~45°.

[0089] In practice, the use of an inclined spray structure ensures that the fan 204 can still blow the liquid mist toward the user even when adjusted to various angles, thus improving user comfort.

[0090] In the embodiments provided by this utility model, such as Figure 3 , Figure 4 As shown, the fan assembly 2 includes:

[0091] The fan motor mounting part 203 is installed inside the air guide duct 201 at one end of the air inlet of the fan 204, away from the atomizing plate fixing seat 103. The hinge 105 is installed at a position away from the atomizing plate fixing seat 103. The drain groove 202 is formed above the hinge 105.

[0092] A fan 204 and a motor 205 that drives the fan 204; the fan 204 and the motor 205 are installed in the fan motor mounting part 203;

[0093] The air guide grid 206 is installed inside the air guide duct 201 at one end of the air outlet of the fan 204.

[0094] It should be noted that the fan 204 and the motor 205 are preferably integrated into one unit; the motor 205 is preferably fixed in the mounting bracket in the middle of the fan motor mounting part 203 by screws.

[0095] It should be noted that, as Figure 5 , Figure 6 As shown, the fan motor mounting part 203 has a notch 2031 around its periphery that can be engaged with the buckle 2012 on the inner wall of the air guide duct 201 for connection.

[0096] It should be noted that a power supply (not shown in the figure) is provided inside the unit 101, preferably a high-capacity rechargeable lithium battery, to power the fan assembly 2 and the humidifier assembly 1.

[0097] In practice, the structure of fan assembly 2 can blow liquid mist in the direction required by the user, providing feasible support for meeting user needs.

[0098] In one implementation, such as Figure 4 , Figure 6 , Figure 7 As shown, the air guide grid 206 has a cross-sectional shape 2064 that is trapezoidal, triangular, or wedge-shaped with an outer width greater than the inner width. A guide recess 2062 is provided on the outer side near the hinge 105, and several interconnected grid strips 2061 are provided in the middle. A downward guide slope 2063 is provided on the inner side of the connection between several grid strips 2061.

[0099] It should be noted that water is most likely to accumulate at the connection between the grid bars 2061. Setting the guide slope 2063 can guide the accumulated water to the inside of the air guide grid 206 and prevent it from flowing to the outside.

[0100] It should be noted that the air guide grid 206 has a flow guide recess 2062 on the outer side near the hinge 105, which can prevent the droplets flowing down the air guide grid from flowing to the outside of the body 101.

[0101] It should be noted that the shape of the cross section 2064 of the air guide grid 206 is a trapezoid, triangle or wedge with the outer width being greater than the inner width. The preferred shape of the cross section 2064 is trapezoidal, which allows the water accumulated on the air guide grid to flow to the inside of the grid.

[0102] In practice, the structure of the air guide grid 206, through the above optimization, can effectively prevent droplets from accumulating and flowing to the outside, thereby providing users with a better user experience.

[0103] In one implementation, such as Figure 5 As shown, the fan motor mounting part 203 has a waist-shaped mist inlet 2032 on one or both sides; the position of the atomizing plate 104 is aligned with one of the waist-shaped mist inlets 2032.

[0104] It should be noted that the fan motor mounting part 203 preferably has waist-shaped mist inlets 2032 on both sides, and the position of the atomizing plate 104 is aligned with one of the waist-shaped mist inlets 2032, so as to ensure that the liquid mist can smoothly enter the fan 204 under different tilt angles without being blocked by the middle of the fan motor mounting part 203.

[0105] In the embodiments provided by this utility model, such as Figure 3 As shown, the air inlet edge of the air guide duct 201 is provided with a rearward-extending fog deflector 2011.

[0106] It should be noted that the air duct 201 is preferably a circular barrel structure, with a fog deflector 2011 extending backward from its upper rear edge. The fog deflector 2011 can block the overflowing liquid mist and form an airflow that is more conducive to the intake of liquid mist, so that the sprayed liquid mist can be completely sucked into the fan 204 without overflowing.

[0107] In practice, the fog deflector 2011 effectively prevents the overflow of liquid mist sprayed from the humidifier, providing users with more humidifying liquid mist and thus improving the user's comfort.
