Description

Technical Field

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

[0002] Currently, most fans on the market consist of a fan head assembly including a housing, impeller, motor, and cover. The impeller and motor are housed within the housing, and the cover fits over the opening of the housing. The housing and cover are then mechanically connected together. While this design is compact, it has some drawbacks. Especially after prolonged use, dust and dirt easily accumulate on the impeller, affecting fan performance and air quality. Users then need to maintain and clean the fan. However, this type of fan requires specialized tools to disassemble the cover, which is relatively difficult and increases maintenance costs. Utility Model Content

[0003] Therefore, it is necessary to address the problems of inconvenient fan disassembly and high maintenance costs in related technologies by providing a fan head assembly and fan that are easy to disassemble and have low maintenance costs.

[0004] A fan head assembly, comprising:

[0005] The first housing and the second housing together enclose an installation cavity;

[0006] A motor and a fan impeller, the motor and fan impeller being located in the mounting cavity, with the motor connected to either the first housing or the second housing; and

[0007] The positioning component includes a first positioning element and a second positioning element, which are respectively disposed in a first housing and a second housing, and are engaged or adsorbed together.

[0008] Since the motor and impeller are located in the mounting cavity, and the motor is connected to either the first or second housing, with the first and second positioning components engaging or adsorbing each other, when operators need to disassemble and maintain the fan head assembly, they only need to fix the first housing and apply force to the second housing, or fix the second housing and apply force to the first housing. This will disengage the first and second positioning components, allowing for maintenance or cleaning of the impeller and other components. In this application, the engaging or adsorbing relationship between the first and second positioning components enables a quick-release structure for the first and second housings, making relative disassembly of the first and second housings easy. Since no specialized disassembly tools are required, maintenance costs are also reduced.

[0009] In some embodiments, the first positioning member and the second positioning member are magnetically engaged with each other.

[0010] In some embodiments, the first housing includes a first bottom wall and a first side wall connected to the first bottom wall; the second housing includes a second bottom wall and a second side wall connected to the second bottom wall;

[0011] The opposite end faces of the first and second side walls are fitted together to enclose the mounting cavity; the first positioning member and the second positioning member are respectively installed on the opposite end faces of the first and second side walls.

[0012] In some embodiments, the opposite end faces of the first sidewall and the second sidewall are respectively provided with a groove and a protrusion that can be inserted into each other;

[0013] The first positioning element is embedded in the bottom wall of the groove, and the second positioning element is embedded in the protrusion.

[0014] In some embodiments, the bottom wall of the groove is provided with a first positioning hole, and the protrusion is provided with a second positioning hole;

[0015] The walls of both the first and second positioning holes are provided with positioning ribs that extend axially.

[0016] The first positioning element is positioned in the first positioning hole by a corresponding positioning rib, and the second positioning element is positioned in the second positioning hole by a corresponding positioning rib.

[0017] In some embodiments, the opposite end faces of the first sidewall and the second sidewall are respectively provided with mating grooves and mating ribs that can be inserted into each other.

[0018] The mating groove extends along the end face of the first side wall and communicates with the interior of the recessed portion, while the mating rib extends along the end face of the second side wall and connects with the protrusion.

[0019] In some embodiments, there are multiple first positioning elements and multiple second positioning elements, and the positions of the first positioning elements correspond one-to-one with the positions of the second positioning elements.

[0020] Multiple first positioning elements are arranged at intervals along the circumference of the first sidewall, and second positioning elements are arranged at intervals along the circumference of the second sidewall.

[0021] In some embodiments, a motor positioning cover is provided on the side of the second bottom wall facing the first housing, the motor is located inside the motor positioning cover, and the motor shaft of the motor passes through the motor positioning cover and extends into the mounting cavity towards the first housing;

[0022] The wind turbine is mounted on the motor shaft.

[0023] In some embodiments, the fan head assembly also includes a stop knob mounted on the motor shaft and used to position the impeller on the motor shaft.

[0024] In some embodiments, the motor positioning cover has a mounting port on the side opposite to the first housing, and a cover plate is detachably mounted on the mounting port.

[0025] In some embodiments, a notch is provided on the second bottom wall, and a plurality of support arms are provided on the edge of the notch. The side of the support arm away from the notch is bent toward the first housing and connected to the outside of the motor positioning cover.

[0026] A fan, including the aforementioned fan head assembly.

[0027] Because the fan uses the aforementioned fan head assembly, similarly, when operators need to disassemble and maintain the fan head assembly, they only need to hold the first housing and apply force to the second housing, or hold the second housing and apply force to the first housing. This will disengage the first and second positioning parts from their snap-fit ​​or suction engagement, allowing for maintenance or cleaning of components such as the impeller. Since no specialized disassembly tools are required, the fan's maintenance costs are reduced. Attached Figure Description

[0045] See Figure 1 , Figure 2 and Figure 3The fan head assembly 100 provided in this application embodiment includes: a first housing 10, a second housing 20, a motor 40, a fan wheel 50, and a positioning assembly 60.

[0046] The first housing 10 and the second housing 20 together enclose a mounting cavity 101. The motor 40 and the impeller 50 are located in the mounting cavity 101, and the motor 40 is connected to either the first housing 10 or the second housing 20. The positioning assembly 60 includes a first positioning member 61 and a second positioning member 62, which are respectively disposed in the first housing 10 and the second housing 20, and are engaged or adsorbed together.

[0047] Since the motor 40 and the impeller 50 are located in the mounting cavity 101, and the motor 40 is connected to the first housing 10 or the second housing 20, and the first positioning member 61 and the second positioning member 62 are engaged or adsorbed, when the operator needs to disassemble and maintain the fan head assembly 100, it is only necessary to fix the first housing 10 and apply force to the second housing 20, or fix the second housing 20 and apply force to the first housing 10, so that the first positioning member 61 and the second positioning member 62 can be released from the engagement or adsorption, and the impeller 50 and other components can be maintained or cleaned. In this application, the quick-release structure of the first housing 10 and the second housing 20 is realized by the engagement or adsorption of the first positioning member 61 and the second positioning member 62, making the relative disassembly of the first housing 10 and the second housing 20 easy to achieve. Since no professional disassembly tools are required, maintenance costs are also reduced.

[0048] In addition, if the motor 40 is connected to the first housing 10, the second housing 20 can be removed; if the motor 40 is connected to the second housing 20, the first housing 10 can be removed, thereby further reducing the difficulty of disassembly.

[0049] In this embodiment, the motor 40 is connected to the second housing 20 as an example. In actual implementation, the motor 40 can also be connected to the first housing 10. The situation of the motor 40 being connected to the first housing 10 is similar and will not be described again here.

[0050] The adsorption and engagement here can be, for example, the first positioning member 61 and the second positioning member 62 magnetically engaging with each other.

[0051] This allows for a quick-release connection between the first positioning member 61 and the second positioning member 62. In some embodiments, the first positioning member 61 and the second positioning member 62 can be magnets with opposite polarities. In other embodiments, the first positioning member 61 and the second positioning member 62 can also be snap-fitted together. For example, the first positioning member 61 can be provided with a slot, and the second positioning member 62 can be provided as a snap-fit ​​post that engages with the slot. This allows for a simple quick-release connection between the first positioning member 61 and the second positioning member 62.

[0052] In this embodiment of the application, combined with Figure 4 , Figure 5 and Figure 6 The first housing 10 includes a first bottom wall 11 and a first side wall 12 connected to the first bottom wall 11. The second housing 20 includes a second bottom wall 21 and a second side wall 22 connected to the second bottom wall 21. Both the first housing 10 and the second housing 20 can be formed as a cover-like structure.

[0053] The opposing end faces of the first sidewall 12 and the second sidewall 22 are fitted together to enclose the mounting cavity 101. The first positioning member 61 and the second positioning member 62 are respectively mounted on the opposing end faces of the first sidewall 12 and the second sidewall 22.

[0054] Thus, during the assembly of the opposite end faces of the first sidewall 12 and the second sidewall 22, the first positioning member 61 and the second positioning member 62 can achieve quick-release engagement, making the engagement structure relatively simple and easy to implement.

[0055] In the embodiments of this application, further, in conjunction with Figure 7 and Figure 8 The opposite end faces of the first sidewall 12 and the second sidewall 22 are respectively provided with a groove 121 and a protrusion 221 that can be inserted into each other.

[0056] The first positioning member 61 is embedded in the bottom wall of the groove portion 121, and the second positioning member 62 is embedded in the protrusion portion 221.

[0057] Thus, when the protrusion 221 is inserted into the groove 121, the first positioning member 61 and the second positioning member 62 can come into contact and achieve adsorption. Of course, the first positioning member 61 can be set to be flush with the bottom wall of the groove 121, and the second positioning member 62 can be set to be flush with the top surface of the protrusion 221, so that the adsorption and engagement of the first positioning member 61 and the second positioning member 62 is smoother.

[0058] Furthermore, a first positioning hole 1210 is provided on the bottom wall of the recessed portion 121, and a second positioning hole 2210 is provided on the protruding portion 221. Positioning ribs 2211 extending axially are provided on the walls of both the first positioning hole 1210 and the second positioning hole 2210. The first positioning member 61 is engaged and positioned in the first positioning hole 1210 by the corresponding positioning rib 2211, and the second positioning member 62 is engaged and positioned in the second positioning hole 2210 by the corresponding positioning rib 2211. This facilitates the installation of the first positioning member 61 into or from the first positioning hole 1210, and also facilitates the installation of the second positioning member 62 into or from the second positioning hole 2210. Additionally, both the first positioning member 61 and the second positioning member 62 can be constructed as columnar members.

[0059] The positioning ribs 2211 ensure that the first positioning member 61 is firmly secured in the first positioning hole 1210, and the second positioning member 62 is firmly secured in the second positioning hole 2210. The number of positioning ribs 2211 can be set as needed, such as 7 and... Figure 8 In the example, the number of positioning ribs 2211 in the first positioning hole 1210 is four, and the four positioning ribs 2211 are evenly distributed circumferentially on the hole wall of the first positioning hole 1210. Similarly, the number of positioning ribs 2211 in the second positioning hole 2210 is four, and the four positioning ribs 2211 are evenly distributed circumferentially on the hole wall of the second positioning hole 2210. Of course, the number and arrangement of the positioning ribs 2211 can be set according to actual needs.

[0060] Furthermore, combined Figures 5-8 The opposite end faces of the first sidewall 12 and the second sidewall 22 are respectively provided with mating grooves 122 and mating ribs 222 that can be inserted into each other.

[0061] The mating groove 122 extends along the end face of the first sidewall 12 and communicates with the interior of the recessed portion 121. The mating rib 222 extends along the end face of the second sidewall 22 and connects with the protrusion 221. Thus, the mating end faces of the first housing 10 and the second housing 20 can have good sealing performance. When the first housing 10 and the second housing 20 are mated, the mating rib 222 of the second housing 20 enters the mating groove 122 of the first housing 10, and the protrusion 221 of the second housing enters the recessed portion 121 of the first housing 10.

[0062] In the embodiments of this application, reference is made to Figure 5 , Figure 6 The number of the first positioning member 61 and the number of the second positioning member 62 can both be multiple, and the positions of the first positioning member 61 and the positions of the second positioning member 62 correspond one-to-one. In the example of this application, three first positioning members 61 and three second positioning members 62 are used for illustration. In specific implementation, the structure formed by the first housing 10 and the second housing 20 is also provided with an opening 102, which is the ventilation port of the fan head assembly 100. The three first positioning members 61 are respectively located in the first side wall 12 at positions avoiding the opening 102, and are arranged at intervals along the circumference of the first side wall 12. The three second positioning members 62 are respectively located in the second side wall 22 at positions avoiding the opening 102, and are arranged at intervals along the circumference of the second side wall 22.

[0063] In this embodiment of the application, combined with Figure 1 and Figure 6A motor positioning cover 30 is provided on the side of the second bottom wall 21 facing the first housing 10. The motor 40 is located inside the motor positioning cover 30, and the motor shaft 41 of the motor 40 passes through the motor positioning cover 30 and extends into the mounting cavity 101 towards the first housing 10. The impeller 50 is mounted on the motor shaft 41. In this way, the impeller 50 and the motor shaft 41 can be connected, and the motor shaft 41 can drive the impeller 50 to rotate when it rotates.

[0064] In some embodiments, combined with Figure 1 and Figure 4 The fan head assembly 100 also includes a stop knob 70, which is mounted on the motor shaft 41 and used to position the impeller 50 on the motor shaft 41.

[0065] For example, the stop knob 70 can be threaded onto the motor shaft 41, and the outer circumferential surface of the stop knob 70 is provided with external teeth, and the impeller 50 is provided with internal teeth at the corresponding positions. By fitting the impeller 50 onto the stop knob 70, the internal teeth and external teeth are meshed and engaged, thereby fixing the impeller 50 and the stop knob 70 relative to each other.

[0066] In this embodiment, reference is continued. Figure 1 The motor positioning cover 30 is also provided with an installation port 31 on the side opposite to the first housing 10, and a cover plate 32 is detachably installed on the installation port 31.

[0067] Thus, the cover plate 32 and the motor positioning cover 30 together define a receiving cavity for mounting the motor 40, and the motor 40 can also be installed in the motor positioning cover 30 through the mounting port 31, or removed from the motor positioning cover 30.

[0068] Furthermore, referring to Figure 6 The second bottom wall 21 has a notch 210, and the edge of the notch 210 has several support arms 23. The side of the support arm 23 away from the notch 210 is bent toward the first housing 10 and connected to the outside of the motor positioning cover 30. In this way, the motor positioning cover 30 can be suspended and fixed on the second housing 20 by the multiple support arms 23.

[0069] This application also provides a fan, including the aforementioned fan head assembly 100. The fan may be, for example, a cooling fan.

[0070] In this embodiment, the fan head assembly 100 includes a first housing 10 and a second housing 20. The first housing 10, without the motor 40 installed, can be removed for cleaning. The first housing 10 and the second housing 20 can be magnetically attached, making them easy to disassemble and clean. This not only solves the problem of inconvenient cleaning in fans of related technologies but also improves fan performance and user experience.

[0071] During installation, first align the impeller 50 with the motor shaft 41, ensuring that the impeller 50 and the motor shaft 41 are coaxial. Secure the impeller 50 to the motor shaft 41 using the stop knob 70. Ensure the impeller 50 and motor shaft 41 are securely and evenly fixed to prevent vibration or noise during operation. Then, align the first positioning members 61 and the second positioning members 62 with each other, insert the mating ribs 222 of the second housing 20 into the mating grooves 122 of the first housing 10, and insert the protrusions 221 of the second housing into the recesses 121 of the first housing 10. Simultaneously, allow the first positioning members 61 and the second positioning members 62 to adhere to each other, thus installing the first housing 10 onto the second housing 20.

[0072] During disassembly, simply hold the second housing 20 in place and pull the first housing 10 away from the second housing 20 to remove the first housing 10, thereby enabling cleaning and maintenance of the impeller 50 and other components.

[0073] 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.

[0074] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
