Description

Technical Field

[0001] This invention belongs to the technical field of housing assembly methods, and particularly relates to a head assembly and a bladeless fan. Background Technology

[0002] Bladeless fans, also known as air multipliers, produce a natural and continuous cool breeze. Because they have no blades, they won't collect dust or injure children's fingers. Even more remarkable is their unique, streamlined, and sleek design. The inspiration for bladed hand dryers comes from the principle of forcing air through a small opening to "swipe" away water from hands. Air multipliers, on the other hand, force air out through a 1.3mm wide, rotating slit. Because the air is forced out through this circle, the volume of air passing through can be increased by up to 15 times, and the speed can reach up to 35 km / h.

[0003] Currently, most bladeless fans on the market have complex assembly of the fan head components, which are basically composed of front and rear air duct parts, outer shell parts, air distribution parts, and handle parts.

[0038] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] like Figure 2 As shown, the present invention provides a head assembly, including an inner housing 1 and an outer housing 2. The interior of the inner housing 1 is configured as a cavity, and an air duct is formed inside the cavity. The outer housing 2 and the outer wall of the inner housing 1 are fixedly connected so that air is discharged from the side wall of the inner housing 1 through the air duct. By designing the inner housing 1 and the air duct as an integrated molding, the assembly of the air duct assembly and multiple parts is reduced, the welding and fixing process is avoided, which makes the process complicated and improves labor productivity.

[0042] Specifically, an air outlet is provided on the side wall of the inner shell 1. Air flows in from the air duct and exits from the air outlet. The outer shell 2 is provided with a snap-fit ​​structure, and the inner shell 1 is provided with a mating structure. The mating structure and the snap-fit ​​structure are fixed together to securely connect the outer shell 2 and the inner shell 1. By snapping and fixing the snap-fit ​​structure and the mating structure together, the inner shell 1 and the outer shell 2 are combined to form a guide vane of a certain length for guiding airflow, thereby completing the fixed connection between the left and right shells.

[0043] The specific structure of the nose assembly will be explained below by describing the installation sequence of the nose assembly.

[0044] like Figure 3 and Figure 6 As shown, it also includes a voice control structure 7, which includes a speaker 71, a microphone 72, and a control panel 73. The speaker 71 and microphone 72 are electrically connected to the control panel 73. The voice control structure 7 can implement control commands for the air head assembly, including controlling the air outlet speed and air volume of the air head assembly via voice, or controlling the start and stop of the air head assembly.

[0045] Furthermore, a mounting groove 11 is provided on the outer wall of the inner housing 1. The mounting groove 11 is formed by multiple connecting plates. A horn 71 is placed inside the mounting groove 11. The shape of the horn 71 is adapted to the shape inside the mounting groove so that the horn 71 and the mounting groove are snapped together and fixed. A first screw post 12 is provided on one side of the mounting groove 11 of the inner housing 1. The horn 71 is locked in place by screws, so that the horn 71 is fixed in the mounting groove 11.

[0046] Furthermore, a handle ring 8 is provided on the inner housing 1, and a sleeve 82 is provided on the handle ring 8. The microphone 72 is fixedly connected to the sleeve 82. In a preferred embodiment, the microphone 72 and the sleeve 82 are glued together so that the microphone 72 is fixed inside the sleeve 82. A receiving groove is provided on the handle ring 8, and a fourth screw post 84 is provided in the receiving groove. The control panel 73 is fixed in the receiving groove, and the control panel 73 is fixedly connected to the fourth screw post 84 by screws, thereby fixing the control panel 73. In addition, the control display module can also be assembled into the handle ring 8 (not shown in the figure).

[0047] like Figure 7 and Figure 8 As shown, the top of the inner shell 1 has an accommodating space, within which a handle ring 8 is disposed. The handle ring 8 is fixedly connected to the opposite side walls of the inner shell 1. A second protrusion 81 is provided on the handle ring 8, and a first mounting groove 13 is provided on the inner wall of the inner shell 1. The second protrusion 81 and the first mounting groove 13 are engaged and fixed to the handle ring 8, thus securing the handle ring 8 to the inner shell 1. A decorative ring 9 is provided on the handle ring 8, and the decorative ring 9 is engaged and fixed to the outer wall of the handle ring 8, thus fitting onto the handle ring 8. A second mounting groove 91 is provided on the decorative ring 9, and the second mounting groove 91 is engaged and fixed to the second protrusion 81 on the handle ring 8. A fourth buckle 92 is provided on the decorative ring 9, and a fourth slot 83 is provided on the handle ring 8. The fourth buckle 92 and the fourth slot 83 are engaged and fixed to the decorative ring 9 and the handle ring 8, thus securing the decorative ring 9 and the handle ring 8 together.

[0048] Furthermore, the decorative ring 9 is fixed to the handle ring 8 so that the microphone 72 is aligned with the sound receiving hole 93 provided on the decorative ring 9.

[0049] Furthermore, symmetrical second protrusions 81 are arranged on the outer wall of the handle ring 8, and a sleeve 82 is arranged between the two second protrusions 81. The handle ring 8 has a ring structure, and the decorative ring 9 has a ring structure. The shapes of the decorative ring 9 and the handle ring 8 are adapted to each other so that the decorative ring 9 and the handle ring 8 are fixedly connected. Of course, it is understandable that the positional relationship between the second protrusions 81, the sleeve 82, and the fourth slot 83 can be adjusted adaptively, as long as the snap-fit ​​fixing of the handle ring 8 and the decorative ring 9 can be achieved.

[0050] Furthermore, the fourth buckle 92 is set at the bottom of the inner wall of the decorative ring 9 so that the fourth buckle 92 and the fourth slot 83 of the handle ring 8 are positioned opposite each other, thereby enabling the decorative ring 9 to be fastened to the handle ring 8, so that the fourth buckle 92 and the fourth slot 83 are engaged and fixed.

[0051] According to the above embodiment, the second mounting groove 91 in the decorative ring 9 is mounted on the second protrusion 81 in the handle ring 8, and the fourth buckle 92 in the decorative ring 9 is snapped into the fourth slot 83 in the handle ring 8, thereby fixing the decorative ring 9 in place and aligning the sound hole 93 in the decorative ring 9 with the microphone 72, thereby completing the assembly of the handle assembly.

[0052] In a preferred embodiment, the second assembly groove 91 is configured as a U-shaped groove.

[0053] Furthermore, the second protrusion 81 in the handle ring 8 is assembled into the first mounting groove 13 in the inner housing 1, and the handle assembly is fixed with screws. At the same time, the internal wiring of the handle assembly, which matches the base motherboard, is led out and secured by the first clip 112 in the inner housing 1.

[0054] Furthermore, the inner shell 1 is configured with a U-shaped structure, and the outer shell 2 comprises two shells, which are symmetrically arranged on the outer wall of the inner shell 1. Of course, it is understood that the shape of the inner shell 1 can also be configured with other structures, such as a ring structure. Here, only the U-shaped structure is described as a specific embodiment, and other shapes of inner shell 1 are within the protection scope of this invention.

[0055] Furthermore, such as Figure 5 As shown, the mating structure includes a through hole 15, and the snap-fit ​​structure includes a first protrusion 21, which is disposed on the outer shell 2 and is inserted and fixedly connected to the through hole 15. The mating structure also includes a first slot 16, and the snap-fit ​​structure also includes a second buckle 23, which is snap-fitted and fixedly connected to the first slot 16. A sealing element 6 is provided around one side of the through hole 15, and the sealing element 6 is disposed on the end face 14 of the inner shell 1 to prevent air leakage from the through hole 15.

[0056] In a preferred embodiment, the seal 6 is made of a sponge-like material, which mainly prevents air from flowing into other parts of the inner housing 1 through the through hole 15, thus preventing air leakage.

[0057] Furthermore, such as Figure 12 As shown, the sealing element 6 includes a body 61, with extended sides vertically arranged at opposite ends of the body 61. The extended sides are fixedly connected to the body 61. In a preferred embodiment, the extended sides and the body 61 are integrally formed. It is understood that the specific structure of the sealing element 6 is mainly determined by the location and number of through holes 15. As long as the sealing element 6 can be enclosed within a certain space through the through holes 15, it is sufficient. After fixing the outer shell 2 and the inner shell 1, the sealing element 6 fills the gap formed between the inner shell 1 and the outer shell 2, thus isolating the air generated within the through holes 15 and preventing air from flowing into other parts of the inner shell 1.

[0058] Furthermore, such as Figure 4As shown, a locking block 22 is provided on the side wall of the outer shell 2, and a second locking groove 17 is provided on the outer wall of the inner shell 1. The locking block 22 and the second locking groove 17 are engaged and fixed. Ribs 19 are provided on the outer wall of the inner shell 1. The outer shell 2 is fastened to the inner shell 1 so that the inner shell 1 and the outer shell 2 form a guide vane for guiding airflow.

[0059] According to the above-described embodiment, the sealing sponge is assembled into the end face 14 of the inner shell 1. Then, the second buckle 23 provided on the outer shell 2 is snapped into the first slot 16 provided on the inner shell 1, and the clip 22 is snapped into the second slot 17 in the inner shell 1. The first protrusion 21 passes through the through hole 15 in the inner shell 1 and is spliced ​​with the rib 19 to form a guide vane of a certain length for guiding air, thereby completing the fixed connection of the outer shell 2. At this time, the sealing sponge is tightly sealed against the inner wall surface 24 of the outer shell 2 to prevent the airflow from the through hole 15 in the inner shell 1 from leaking to other areas.

[0060] like Figure 9 and Figure 10 As shown, it also includes a diversion structure, which is fixedly connected to the inner shell 1 so that air flows from the diversion structure into the air duct of the inner shell 1. The airflow formed by the diversion structure and the air duct inside the inner shell 1 combine to form an internal airflow channel cavity, so that air flows from the diversion structure into the air duct inside the inner shell 1 and is then discharged from the air outlet, thereby forming air circulation.

[0061] Furthermore, the first diverter 3 includes a first receiving chamber 31, and the second diverter 4 includes a second receiving chamber 41. The first diverter 3 and the second diverter 4 have the same structure and are symmetrically arranged so that the first diverter 3 and the second diverter 4 can be engaged, and the first receiving chamber 31 and the second receiving chamber 41 form an air flow channel.

[0062] Specifically, the diversion structure includes a first diversion component 3 and a second diversion component 4. The first diversion component 3 and the second diversion component 4 are snapped together to form a receiving chamber, through which air flows into the air duct of the inner shell 1. The first diversion component 3 is provided with a third buckle 33, and the second diversion component 4 is provided with a third slot 42. The third buckle 33 and the third slot 42 are inserted and fixed to fix the first diversion component 3 and the second diversion component 4. The first diversion component 3 is provided with a first fixing hole 32, and the second diversion component 4 is provided with a second fixing hole 43. A fixing member is provided at the bottom of the inner shell 1. The first fixing hole 32 and the second fixing hole 43 are respectively locked and fixed to the fixing member to fix the first diversion component 3, the second diversion component 4, and the inner shell 1.

[0063] According to the above embodiment, the third buckle 33 in the first diverter 3 is engaged with the third slot 42 in the second diverter 4, completing the connection between the first diverter 3 and the second diverter 4, so that the first receiving chamber 31 in the first diverter 3 and the second receiving chamber 41 in the second diverter 4 combine to form an airflow diversion channel. Next, the first fixing hole 32 in the first diverter 3 and the second fixing hole 43 in the second diverter 4 are respectively assembled into the second screw post 111 in the inner shell 1, achieving pre-fixation of the first diverter 3 and the second diverter 4, and causing the airflow diversion channel formed by the combination of the first diverter 3 and the second diverter 4 to combine with the air duct cavity 110 in the inner shell 1 to form an internal airflow channel cavity. Multiple baffles 18 are provided on the side wall of the air duct cavity 110.

[0064] like Figure 11 As shown, it also includes a bottom cover 5, which has a through hole 51. The first diverter 3 and the second diverter 4 are pre-fixed to the inner shell 1 and then assembled and fixed to the through hole 51. The bottom cover 5 has an annular sidewall 53, and the outer shell 2 has a stop 25. The stop 25 and the annular sidewall 53 abut against each other. The inner shell 1, the outer shell 2, and the bottom cover 5 are fixedly connected by screws.

[0065] According to the above embodiment, the through hole 51 in the bottom cover 5 passes through the first diverter 3 and the second diverter 4, and the annular sidewall 53 limits the stop 25 in the outer shell 2 to prevent deformation of the outer shell 2. Finally, by driving screws through the third screw post 52 in the bottom cover 5, the through hole 15 of the first diverter 3 and the second diverter 4 of the second diverter 4, the first fixing hole 32, the second fixing hole 43 and the second screw post 111 in the inner shell 1, the bottom cover 5, the first diverter 3, the second diverter 4 and the inner shell 1 are completely fixedly connected, thereby completing the overall connection of the machine head assembly, and the internal wiring of the handle assembly passes through the mounting hole 54 in the bottom cover 5 and is finally connected to the main board of the base part.

[0066] like Figure 1 As shown, the present invention also provides a bladeless fan, including a base on which the aforementioned head assembly is disposed. The head assembly and bladeless fan provided by the present invention have an air duct inside the inner housing 1, employing an integrated design of the air duct and inner housing. The inner and outer housings are spliced ​​together to form guide vanes, reducing the number of parts and improving production efficiency.
