Description

Technical Field

[0001] This application relates to the field of fan technology, and in particular to a fan head assembly and a fan. Background Technology

[0002] Currently available atomizing fans use long air ducts and high-speed blades. These blades consist of a hub and blades connected to the outer periphery of the hub. During operation, the blades rotate to generate airflow, which is then blown out through the front grille. There is a windless zone between the hub and the front grille, resulting in a high-pressure zone with no airflow and a low-pressure zone with airflow on the air outlet side of the front grille. The mist blown out of the outlet flows through the high-pressure zone. Therefore, the pressure difference between the high-pressure and low-pressure zones causes the mist to flow from the high-pressure zone to the low-pressure zone, which in turn causes the mist to flow back onto the grille and accumulate and drip, resulting in a poor user experience. Summary of the Invention

[0003] Therefore, it is necessary to provide a head assembly and fan to address the issue of condensation on the mesh cover.

[0004] A head assembly, comprising:

[0005] The outer casing includes a main body having an airflow channel formed therein and a front mesh cover disposed on one side of the main body;

[0006] The first fan blade is disposed within the air delivery channel and includes a hub and a plurality of blades connected to the outer periphery of the hub;

[0007] A mist outlet is located on the air outlet side of the first fan blade; and

[0008] The second fan blade is disposed between the first fan blade and the mist outlet, and is used to discharge air on the same side as the first fan blade when rotated in a controlled manner.

[0009] There is a windless zone between the wheel hub and the front grille, and the second fan blade and the mist outlet are both located within the windless zone.

[0010] In one embodiment, the housing further includes a bracket fitted within the air supply duct, the bracket being located on the side of the first fan blade facing the air outlet and within the windless zone;

[0011] The bracket has an internal structure forming a compensation channel that is connected to and extends in the same direction as the air supply channel. The cross-sectional area of ​​the compensation channel is not greater than the cross-sectional area of ​​the windless zone. The second fan blade and the mist outlet are both connected to the compensation channel of the bracket.

[0012] In one embodiment, the mist outlet is provided with a mist outlet, which opens toward the air outlet of the air supply channel;

[0013] The head assembly also includes a flow divider, which is connected to one end of the bracket near the air outlet. The flow divider has a mist outlet and an air outlet that are spaced apart from each other and open towards the air outlet. The mist outlet is connected to the mist outlet, and the air outlet is connected to the compensation channel.

[0014] In one embodiment, the flow divider includes a flow divider section, one end of which facing the air outlet has the mist outlet and the air outlet, and the flow divider section is constructed with a partitioned mist outlet space and an air outlet space, the mist outlet space being connected to the mist outlet and used to communicate with the mist outlet, and the air outlet space being connected to the air outlet and used to communicate with the compensation flow channel.

[0015] In one embodiment, the diversion section includes a first main board, a first side plate, and a diversion plate. The side plate and the diversion plate both protrude from the same side surface of the main board. The side plate extends along the periphery of the main board to jointly form a diversion space with an opening on one side. Both ends of the diversion plate along its own extension direction are connected to the side plate, and the diversion space is divided into a fogging space and an air passage space. The main board has a fogging port communicating with the fogging space and an air passage port communicating with the air passage space.

[0016] In one embodiment, the diverter further includes an installation section, one end of which is connected to the end of the diverter section facing away from the air outlet, and the other end is mated to the end of the bracket near the air outlet.

[0017] In one embodiment, the mist outlet includes a mist outlet section and a connecting section connected together. The mist outlet section has a mist outlet, and the connecting section has a connecting flow channel that communicates with the mist outlet. The mist outlet section is located within the air supply flow channel, and the connecting section extends at least partially out of the air supply flow channel.

[0018] In one embodiment, the mounting section includes a second main board and a second side plate. The second main board surrounds the outer side of the end of the diversion section opposite to the air outlet. The second side plate protrudes from the surface of the second main board opposite to the diversion section and extends circumferentially along the second main board to jointly form a mounting space. The bracket extends into the mounting space and is sealed to the second side plate.

[0019] In one embodiment, the front cover has a through-hole, and one end of the mist outlet and the air outlet on the diverter extends out of the air delivery channel through the through-hole.

[0020] A fan, comprising:

[0021] The head assembly in the foregoing embodiments;

[0022] The fuselage is connected to the head assembly;

[0023] The atomizer is connected to the atomizing element of the head assembly.

[0024] The aforementioned head assembly and fan include a housing, a first fan blade, a mist outlet, and a second fan blade. The housing includes a main body with an internal airflow channel and a front grille disposed on one side of the main body; the first fan blade is disposed within the airflow channel and includes a hub and multiple blades connected to the outer periphery of the hub; the mist outlet is disposed on the air outlet side of the first fan blade; and the second fan blade is disposed between the first fan blade and the mist outlet, and is used to discharge air on the same side as the first fan blade when controlled to rotate; wherein, there is a windless zone between the hub and the front grille, and the second fan blade and the mist outlet are both located within the windless zone. This application utilizes a second fan blade positioned within a windless zone. Controlling the rotation of this second fan blade generates airflow, which flows through the windless zone to the outlet side of the front grille. This ensures a faster airflow rate within the high-pressure zone at the outlet side of the front grille, balancing the pressure difference between the high-pressure and low-pressure zones. This reduces the likelihood of fog flowing back to the front grille, causing condensation and dripping onto its surface. Simultaneously, the cooperation between the first and second fan blades achieves optimal airflow speed and volume, resulting in a stronger airflow. Combined with the mist-discharging component, this rapidly circulates indoor air, achieving suitable humidity and a cooling effect. Attached Figure Description

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0047] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0048] Please see Figures 1 to 6 One embodiment of this application provides a head assembly 200, which includes a housing 20, a first fan blade 21, a mist outlet 23, and a second fan blade 22.

[0049] The outer casing 20 includes a main body 201 in which an airflow channel 202 is formed and a front mesh cover 203 disposed on one side of the main body 201.

[0050] The first fan blade 21 is disposed within the airflow duct 202 and includes a hub 211 and multiple blades 212 connected to the outer periphery of the hub 211. A mist outlet 23 is disposed on the air outlet side of the first fan blade 21. The second fan blade 22 is disposed between the first fan blade 21 and the mist outlet 23, and is used to discharge air on the same side as the first fan blade 21 when rotated under controlled conditions. A windless zone exists between the hub 211 and the front grille 203, and both the second fan blade 22 and the mist outlet 23 are located within this windless zone.

[0051] Understandably, when the first fan blade 21 rotates under control, both the hub 211 and the blades 212 rotate around their own axes. During this rotation, the blades 212 draw in outside air from the air inlet of the air supply duct 202, accelerating the airflow to form an airflow, which is then blown out from the air outlet of the air supply duct 202 through the front grille 203. The hub 211, however, is used to control the synchronous rotation of the blades 212, and its rotation does not generate airflow. Therefore, within the air supply duct 202, there is no airflow between the hub 211 and the front grille 203, or the airflow rate and volume are relatively low, resulting in a large windless zone between them.

[0052] Please see Figure 5 In other words, the hub 211 can be defined as having a projection area on the front grille 203 along the axial direction of the first fan blade 21. The area through which this projection passes from the hub 211 along the axial direction of the first fan blade 21 onto the front grille 203 can be considered a windless zone. Correspondingly, on the air outlet side of the front grille 203, the projection area of ​​the hub 211 along the axial direction of the first fan blade 21 has a slower airflow rate and higher air pressure, thus forming a high-pressure zone; the projection area of ​​the blade 212 along the axial direction of the first fan blade 21 has a faster airflow rate and lower air pressure, thus forming a low-pressure zone. Therefore, on the air outlet side of the front grille 203, there is airflow from the high-pressure zone to the low-pressure zone.

[0053] It should be noted that the definition of the windless zone in this application is an illustrative example for the convenience of understanding the technical solution of this application, and the exact definition of the windless zone should be based on the actual situation.

[0054] Understandably, in this application, the mist outlet 23 is located in a windless area and is used to blow mist into the air outlet of the air supply channel 202. That is to say, after the mist outlet 23 blows the mist to the air outlet side of the front cover 203, the mist is located in the high-pressure area. Under the action of the pressure difference, the mist will flow to the low-pressure area and may flow back to the front cover to generate condensation and drip, which is detrimental to environmental hygiene.

[0055] This application utilizes a second fan blade 22 positioned within a windless zone. The rotation of the second fan blade 22 generates airflow, which flows through the windless zone to the outlet side of the front grille 203. This ensures a faster airflow rate within the high-pressure zone at the outlet side of the front grille 203, balancing the pressure difference between the high-pressure and low-pressure zones. This reduces the likelihood of fog reflux back to the front grille, causing condensation and dripping onto the grille surface. Simultaneously, the cooperation of the first fan blade 21 and the second fan blade 22 achieves optimal airflow speed and volume, resulting in a stronger airflow. Combined with the mist outlet 23, this allows for rapid circulation of indoor air, achieving suitable humidity and a cooling effect.

[0056] It should be noted that, in this application, the airflow rate generated by the second fan blade 22 needs to meet a preset condition with the airflow rate generated by the first fan blade 21. The specific type of the preset condition is not limited.

[0057] In some embodiments, the airflow velocity generated by the first fan blade 21 is defined as V1, and the airflow velocity generated by the second fan blade 22 is defined as V2. The preset condition is the ratio of V1 to V2, and this preset condition needs to ensure a pressure difference balance between the high-pressure and low-pressure areas on the air outlet side of the front grille 203, and to reduce the backflow of mist into the front grille. Therefore, the ratio of V1 to V2 can be 1, meaning that the airflow velocity V1 generated by the first fan blade 21 and the airflow velocity V2 generated by the second fan blade 22 are equal in magnitude.

[0058] In some embodiments (not illustrated), a windless cavity is formed inside the hub, the second fan blade is disposed inside the windless cavity, and there is a windless zone between the hub and the front grille, with the mist outlet located within the windless zone.

[0059] It is understood that the windless zone is defined in the same way as in the aforementioned embodiments, and the windless cavity has the same properties as the windless zone. There is no airflow within the windless cavity, or the airflow rate and volume are relatively small. In this application, the windless cavity and the windless zone are directly connected. The second fan blade is located within the windless cavity, which helps to reduce the space required for assembly, making the head assembly structure compact and reducing the overall size of the head assembly.

[0060] In some embodiments, please refer to Figure 2 and Figure 3 The housing 20 also includes a bracket 205 fitted into the air supply duct, the bracket 205 being located on the side of the first fan blade 21 facing the air outlet and located in the windless zone.

[0061] The bracket 205 has a compensation channel 206 that is connected to and extends in the same direction as the air supply channel 202. The cross-sectional area of ​​the compensation channel 206 is not greater than the cross-sectional area of ​​the windless zone. The second fan blade 22 and the mist outlet 23 are both connected to the compensation channel 206 of the bracket 205.

[0062] It is understood that, in this application, the cross-sectional area of ​​the windless zone can be considered as the projected area of ​​the hub 211 along the axial direction of the first fan blade 21, or the cross-sectional area of ​​the hub 211. Therefore, the statement that the cross-sectional area of ​​the compensation channel 206 is not greater than the cross-sectional area of ​​the windless zone means that, on the projection along the axial direction of the first fan blade 21, the projection of the compensation channel 206 can be completely contained within the projection of the hub 211; that is, the cross-sectional area of ​​the compensation channel 206 is not greater than the cross-sectional area of ​​the hub 211. In this way, the bracket 205 will not obstruct the airflow generated by the blades 212 of the first fan blade 21, ensuring that the outlet airflow and outlet air velocity of the head assembly 200 meet the user's needs.

[0063] Meanwhile, the bracket 205 enables the airflow generated by the second fan blade 22 and the mist blown out by the mist outlet 23 to flow independently within the compensation channel 206, which can avoid the influence of the airflow generated by the first fan blade 21 and achieve stable blowing of airflow and mist within the compensation channel 206, so as to better adjust the pressure difference balance between the high-pressure area and the low-pressure area on the air outlet side of the front cover 203.

[0064] In some embodiments, please refer to Figure 2 and Figure 3 The mist outlet 23 has a mist outlet 232 facing the air outlet opening of the air supply channel 202. It can be understood that the mist outlet 23 blows mist out through the mist outlet 232, and guides the mist towards the air outlet of the air supply channel 202, thereby shortening the path of the mist towards the air outlet and ensuring atomization effect.

[0065] The head assembly 200 also includes a flow divider 24, which is connected to the end of the bracket 205 near the air outlet. The flow divider 24 has a mist outlet 2411 and an air outlet 2413 that are spaced apart from each other and both open towards the air outlet. The mist outlet 2411 is connected to the mist outlet 232, and the air outlet 2413 is connected to the compensation channel 206.

[0066] Understandably, in this application, the airflow generated by the second fan blade 22 can flow through the compensation channel 206 and be directly blown out from the air outlet 2413, and the mist blown out by the mist outlet 23 through the mist outlet 232 can be directly blown out from the mist outlet 2411. In this way, the airflow and mist in the compensation channel can be allowed to flow separately, so as to avoid them from converging and affecting each other, so as to achieve stable blowing of airflow and mist in the compensation channel 206, thereby better regulating the pressure difference balance between the high pressure area and the low pressure area on the air outlet side of the front cover 203.

[0067] In some embodiments, please refer to Figure 2 and Figure 3 The diverter 24 includes a diverter section 241. The diverter section 241 has a mist outlet 2411 and an air outlet 2413 at one end facing the air outlet. The diverter section 241 is constructed with a partitioned mist outlet 2412 and an air outlet 2414. The mist outlet 2412 is connected to the mist outlet 2411 and is used to communicate with the mist outlet 232. The air outlet 2414 is connected to the air outlet 2413 and is used to communicate with the compensation channel 206.

[0068] Understandably, in this application, the airflow generated by the second fan blade 22 flows sequentially through the compensation channel 206 and the air passage space 2414 until it exits from the air passage port 2413. The mist blown out by the mist outlet 23 through the mist outlet 2411 also needs to flow through the mist space 2412 before exiting from the mist outlet 2411. The mist passage space 2412 is directly connected to the mist outlet 232 and guides the flow of mist, optimizing its path to ensure atomization. The air passage space 2414 is directly connected to the compensation channel 206, providing a spatial transition between the compensation channel 206 and the air passage port 2413, and guiding the airflow to better balance the pressure difference between the high-pressure and low-pressure areas on the air outlet side of the front grille 203.

[0069] The specific structure of the diversion section 241 is not limited. For some embodiments, please refer to... Figure 6 The diversion section 241 includes a first main board 2415, a first side plate 2416, and a diversion plate 2417. The first side plate 2416 and the diversion plate 2417 both protrude from the same side surface of the first main board 2415. The first side plate 2416 extends along the periphery of the first main board 2415 to jointly form a diversion space with an opening on one side. Both ends of the diversion plate 2417 along its own extension direction are connected to the first side plate 2416, and the diversion space is divided into a fogging space 2412 and an air passage space 2414. The first main board 2415 has a fogging port 2411 communicating with the fogging space 2412 and an air passage port 2413 communicating with the air passage space 2414.

[0070] It is understood that in this application, the end of the mist outlet 23 with the mist outlet 232 is sealed to the first side plate 2416 and the diverter plate 2417 that surround the mist space 2412. This can prevent the leakage of condensate generated during the flow of mist in the mist space 2412. At the same time, the mist outlet 232 can be directly connected to the mist space 2412 and flow to the mist outlet 2411 under the guidance of the first side plate 2416 and the diverter plate 2417 that surround the mist space 2412.

[0071] In some embodiments, please refer to Figure 4 and Figure 5 The diversion component 24 also includes an installation section 242, one end of which is connected to the end of the diversion section 241 facing away from the air outlet, and the other end is connected to the end of the bracket 205 near the air outlet.

[0072] In some embodiments, please refer to Figure 6 The mounting section 242 includes a second main board 2422 and a second side plate 2423. The second main board 2422 surrounds the outer side of the end of the diversion section 241 facing away from the air outlet. The second side plate 2423 protrudes from the surface of the second main board 2422 facing away from the diversion section 241 and extends circumferentially along the second main board 2422 to jointly form the mounting space 2421. The bracket 205 extends into the mounting space 2421 and is sealed and fitted with the second side plate 2423.

[0073] It is understandable that the bracket 205 extends into the installation space 2421 so that the installation space 2421 partially overlaps with the compensation channel 206, so as to achieve stable assembly of the diverter 24 and the bracket 205, and the structure is compact.

[0074] In some embodiments, please refer to Figure 2 and Figure 3 The front cover 203 has a through-hole 204, and one end of the mist outlet 2411 and air outlet 2413 on the diverter 24 extends out of the air supply channel 202 through the through-hole 204.

[0075] It is understandable that the airflow generated by the second fan blade 22 and the mist blown out by the mist outlet 23 can be directly guided through the diverter 24 to the air outlet side of the front cover 203 via the air supply channel 202. This avoids the influence of the airflow generated by the first fan blade 21 and achieves stable blowing of airflow and mist in the compensation channel 206, so as to better adjust the pressure difference balance between the high-pressure area and the low-pressure area on the air outlet side of the front cover 203.

[0076] In some embodiments, please refer to Figure 2 and Figure 3The mist outlet 23 includes a mist outlet section 231 and a connecting section 233 connected together. The mist outlet section 231 is provided with a mist outlet 232. The connecting section 233 is formed with a connecting flow channel 234 communicating with the mist outlet 232. The mist outlet section 231 is located in the air supply flow channel 202. The connecting section 233 extends at least partially out of the air supply flow channel 202.

[0077] In some embodiments, please refer to Figure 2 and Figure 3 The head assembly 200 also includes a drive component 25, which is connected between the first fan blade 21 and the second fan blade 22 and is used to drive the first fan blade 21 and the second fan blade 22 to rotate around their own axis.

[0078] The specific design of the drive component 25 is not limited; for some embodiments, please refer to [link / reference]. Figure 2 and Figure 3 The drive unit 25 is a dual-axis motor.

[0079] Please see Figure 7 In another aspect, this application provides a fan 100, which includes a body 300, an atomizer, and a head assembly 200 as described in the previous embodiments. The body 300 is connected to the head assembly 200; the atomizer is connected to the atomizing element of the head assembly 200.

[0080] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
