Description

Technical Field

[0001] This utility model relates to the field of fans, and in particular to a housing assembly and a bladeless fan. Background Technology

[0002] As is well known, traditional bladeless fans typically require a dust filter at the air inlet. Air flows through the dust filter before entering the fan's casing. However, this structure suffers from a single airflow path, resulting in low intake efficiency and impacting the fan's output performance and overall performance. Furthermore, the airflow can easily cause the casing to vibrate, leading to the dust filter loosening or falling off, reducing its dust-proofing effect and increasing maintenance difficulty.

The inner shell is provided with a first mounting structure for connecting the inner shell and a lamp body. The outer cover is mounted on the outer periphery of the inner shell, and a second air inlet is provided on the side of the outer cover. The first air inlet and the second air inlet overlap each other. The outer cover is provided with a second mounting structure for connecting a dustproof net. The top of the inner shell and the top of the outer cover are connected relative to each other via the connecting structure, and a gap exists between the side of the inner shell and the side of the outer cover.

[0006] The housing assembly according to this utility model embodiment has at least the following beneficial effects: the first air inlet of the inner shell and the second air inlet of the outer casing overlap each other, forming a highly efficient air intake channel. The inner shell and the outer casing have a gap on their sides, which provides an additional flow path for air, preventing excessive congestion or turbulence during air intake, ensuring smooth airflow into the fan and improving air intake efficiency. Simultaneously, the gap helps dissipate heat inside the fan, creating a natural convection effect, reducing the temperature of internal components, and ensuring the stability and reliability of the equipment during long-term operation.

[0007] In addition, the gap design makes the connection between the inner shell and the outer cover more flexible, which helps to absorb some vibration and expansion, thereby reducing the possibility of the dust cover falling off, and thus further enhancing the product's durability and service life.

[0032] Reference Figure 1A housing assembly includes: an inner shell 100, an outer cover 300, and a connecting structure 700. The bottom of the inner shell 100 is provided with a support base 110, and a first air inlet 150 is provided on the side of the inner shell 100. The inner shell 100 is provided with a first mounting structure 180 for connecting the inner shell 100 and a lamp body. The outer cover 300 is mounted on the outer periphery of the inner shell 100, and a second air inlet 350 is provided on the side of the outer cover 300. The first air inlet 150 and the second air inlet 350 overlap each other. The outer cover 300 is provided with a second mounting structure 330 for connecting a dustproof net. The top of the inner shell 100 and the top of the outer cover 300 are connected relative to each other by the connecting structure 700, and a gap 200 exists between the sides of the inner shell 100 and the sides of the outer cover 300. The first air inlet 150 of the inner shell 100 and the second air inlet 350 of the outer cover 300 overlap to form an efficient air intake channel. The inner shell 100 and the outer cover 300 have a gap 200 on their sides. This gap 200 provides an additional airflow path, preventing excessive air congestion or turbulence during air intake, ensuring smooth airflow into the fan and improving intake efficiency. Simultaneously, the gap 200 helps dissipate heat inside the fan, creating a natural convection effect, reducing the temperature of internal components, and ensuring the stability and reliability of the equipment during long-term operation. Furthermore, the gap 200 design allows for a more flexible connection between the inner shell 100 and the outer cover 300, helping to absorb some vibration and expansion, thereby reducing the possibility of the dust cover falling off and further enhancing the product's durability and lifespan.

[0033] Furthermore, a baffle is provided between the side of the inner shell 100 and the side of the outer cover 300, which further optimizes the airflow path, reduces eddies and resistance during airflow, and improves the air intake efficiency of the fan.

[0034] Furthermore, a sealing strip is provided at the connection between the inner shell 100 and the outer cover 300 to prevent air leakage and ensure that all air enters the fan through the designed air intake channel, thereby further improving air utilization efficiency.

[0035] In some embodiments, reference is made to Figure 2A snap-fit ​​structure 600 is provided between the bottom of the outer casing 300 and the bottom of the inner shell 100. The snap-fit ​​structure 600 is used to snap and fix the bottoms of the outer casing 300 and the inner shell 100 together. The snap-fit ​​structure 600 allows for quick assembly and disassembly of the outer casing 300 and the inner shell 100, improving production efficiency and user experience. At the same time, this snap-fit ​​method enhances the connection strength between the outer casing 300 and the inner shell 100, ensuring that the outer casing 300 will not loosen or shift due to vibration or external force during fan operation, thus improving product stability and reliability. Furthermore, the design of the snap-fit ​​structure 600 also helps maintain the uniformity of the gap 200 between the inner shell 100 and the outer casing 300, further optimizing the airflow path and improving the fan's intake efficiency.

[0036] In some embodiments, reference is made to Figure 3 A support step 140 is provided between the side of the inner shell 100 and the support base 110. The bottom of the inner shell 100 rests on the support step 140, and a snap-fit ​​structure 600 is provided at the support step 140. The support step 140 provides stable bottom support for the inner shell 100, ensuring its stability during installation and use. The bottom of the inner shell 100 resting on the support step 140 makes the weight distribution of the inner shell 100 more even, reducing the risk of deformation due to excessive local stress. The snap-fit ​​structure 600, located at the support step 140, further enhances the stability of the connection between the outer cover 300 and the bottom of the inner shell 100, ensuring that the outer cover 300 and the inner shell 100 can fit tightly together during fan operation without relative displacement, improving the overall stability and service life of the product. At the same time, this design allows for more precise assembly of the outer cover 300 and the inner shell 100, helping to optimize the airflow path and improve the fan's intake efficiency.

[0037] It is conceivable that anti-slip pads or rubber pads can be provided on the surface of the supporting step 140 to increase the friction between the bottom of the inner shell 100 and the supporting step 140, preventing the inner shell 100 from shifting due to vibration or external force during use. The anti-slip pads can also act as a buffer, reducing collisions and wear between the inner shell 100 and the supporting step 140, and extending the service life of the components.

[0038] In some embodiments, reference is made to Figure 3The snap-fit ​​structure 600 includes a snap-fit ​​component, a first snap-fit ​​groove 160 located at the bottom of the inner shell 100, and a second snap-fit ​​groove 360 ​​located at the bottom of the outer cover 300. The first snap-fit ​​groove 160 and the second snap-fit ​​groove 360 ​​are flush with each other, and the snap-fit ​​component has at least two different parts that snap into the first snap-fit ​​groove 160 and the second snap-fit ​​groove 360 ​​respectively. The snap-fit ​​effect of the snap-fit ​​component into the first snap-fit ​​groove 160 and the second snap-fit ​​groove 360 ​​not only improves the stability and reliability of the connection between the bottom of the outer cover 300 and the inner shell 100, but also allows the snap-fit ​​component to be adjusted within a certain range to accommodate components of different sizes or tolerances, enhancing the product's versatility and adaptability. Through the tight fit between the snap-fit ​​component and the two snap-fit ​​grooves, the connection between the outer cover 300 and the inner shell 100 is more secure, effectively resisting vibration and external impact during fan operation, ensuring long-term stable operation of the product. At the same time, this snap-fit ​​method simplifies the assembly process, improves production efficiency, and reduces production costs.

[0039] Specifically, the snap-fit ​​component may have two snap-fit ​​blocks, used for snapping into the first slot 160 and the second slot 360 respectively. Furthermore, the snap-fit ​​component may be designed with an elastic deformation capability so that it can automatically adapt to the dimensional differences between the first slot 160 and the second slot 360 during installation, improving the compatibility and reliability of the snap-fit.

[0040] In some embodiments, reference is made to Figure 4 The connection structure 700 includes a first connection hole 170 and a second connection hole 370. The first connection hole 170 is located on the top of the inner shell 100, and the second connection hole 370 is located on the top of the outer casing 300. The first connection hole 170 and the second connection hole 370 are coaxial and can be connected relative to each other by fasteners. This design not only provides a reliable mechanical connection, ensuring a stable connection between the tops of the inner shell 100 and the outer casing 300, but also allows for adjustment of the tightness of the connection as needed to accommodate inner shells 100 and outer casings 300 of different materials or thicknesses. The use of fasteners enhances the strength and stability of the connection, effectively resisting torsional and tensile forces during fan operation and extending the product's lifespan. Furthermore, the coaxial design ensures the coaxiality of the inner shell 100 and the outer casing 300, helping to maintain the overall balance of the fan, reducing noise and vibration during operation, and improving the user experience.

[0041] Specifically, the fastener can be a screw or a rivet. The specific implementation method is not unique, but can be adjusted according to the actual situation, and no restrictions are imposed here.

[0042] In some embodiments, reference is made to Figure 6The inner shell 100 has an opening 190 at its top, and a first mounting structure 180 is located inside the opening 190. The inner shell 100 has a connecting post 175, with a first connecting hole 170 located at the connecting post 175, which is located outside the opening 190. The first mounting structure 180 being located inside the opening 190 facilitates the installation and removal of the lamp body, improving operational convenience and efficiency. The connecting post 175 being located outside the opening 190, and the first connecting hole 170 being located at the connecting post 175, not only optimizes the space utilization at the top of the inner shell 100 but also provides a stable connection point for the connecting structure 700. The design of the connecting post 175 enhances the structural strength of the top of the inner shell 100, ensuring that it will not be damaged due to excessive localized stress when connected by fasteners, thus improving product reliability and service life. Meanwhile, the combination of the opening 190 and the connecting pile 175 makes the top design of the inner shell 100 more reasonable, which helps to realize the multi-functional integration of the inner shell 100 and improve the overall performance of the product.

[0043] In some embodiments, reference is made to Figure 6 The first mounting structure 180 includes a screw-in groove located inside the opening 190. The screw-in groove provides a quick and secure connection for installing the lamp body. The screw-in design allows the lamp body to be easily screwed into or out of the inner housing 100 without additional tools, greatly facilitating installation and replacement operations for users. Simultaneously, the screw-in groove cooperates with the screws on the lamp body to ensure that the lamp body will not loosen or fall off due to vibrations from fan operation after installation, improving product safety and reliability.

[0044] In some embodiments, reference is made to Figure 5 The second mounting structure 330 includes a mounting slot disposed on the outer cover 300, which is used to engage the dust filter. The mounting slot makes the installation of the dust filter more secure and convenient. The dust filter can be fixed to the outer cover 300 by snapping, without the need for additional fasteners or complicated operations, improving installation efficiency. The shape and size of the mounting slot match the edges of the dust filter, ensuring that the dust filter fits tightly against the outer cover 300 after installation, effectively preventing dust from entering the fan and improving the fan's dustproof performance. At the same time, the snap-fit ​​method also facilitates the disassembly and cleaning of the dust filter, reducing maintenance costs and extending the fan's lifespan.

[0045] In some embodiments, reference is made to Figure 2Both the inner shell 100 and the outer cover 300 are cylindrical, and multiple connecting structures 700 are evenly distributed around the inner shell 100 and the outer cover 300. The even distribution of these connecting structures 700 ensures balanced circumferential stress on the inner shell 100 and the outer cover 300, preventing deformation or loosening caused by uneven local stress, and improving the overall strength and reliability of the product. Furthermore, the cylindrical structure design makes the shell assembly more aesthetically pleasing and conforms to modern product design concepts, enhancing the product's market competitiveness.

[0046] Furthermore, the cylindrical structures of the inner shell 100 and the outer cover 300 are equipped with reinforcing ribs to enhance their structural strength and prevent deformation due to airflow impact or external collision during fan operation. Additionally, shock-absorbing pads are provided at the connecting structure 700 to reduce vibration transmission between the inner shell 100 and the outer cover 300, thereby reducing noise and vibration during fan operation and improving the user experience.

[0047] A second aspect of this utility model provides an embodiment of a bladeless fan, including the housing assembly described above. The first air inlet 150 of the inner housing 100 and the second air inlet 350 of the outer casing 300 overlap to form a highly efficient air intake channel. The inner housing 100 and the outer casing 300 have a gap 200 on their sides, which provides an additional airflow path, preventing excessive air congestion or turbulence during air intake, ensuring smooth airflow into the fan and improving air intake efficiency. Simultaneously, the gap 200 helps dissipate heat inside the fan, creating a natural convection effect, reducing the temperature of internal components, and ensuring the stability and reliability of the device during long-term operation.

[0048] 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. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
