[0002] Fans and other air-dissipating devices are household appliances that use an electric motor to drive the fan blades to rotate, thereby accelerating the circulation of air. They are mainly used for cooling and ventilating the air.

[0003] To purify the air and enhance fan functionality, fans capable of releasing negative ions have appeared on the market. However, the improper placement of the negative ion generator in these fans affects the diffusion efficiency of negative ions, limiting their air purification effect. Furthermore, prolonged use of the negative ion generator can attract dust, reducing its emission efficiency and compromising air purification effectiveness. Utility Model Content

[0004] In view of this, the present invention provides an installation structure and an air outlet device to solve the problems of improper setting of negative ion generators in existing fans, which affects the air purification effect, and long-term adsorption of dust, which cannot guarantee the air purification efficiency.

[0005] In a first aspect, this utility model provides an installation structure for use in an air outlet device, the air outlet device including an air duct and an ion generator, the ion generator including an emitter head, the emitter head being detachably connected to the air inlet side of the air duct via the installation structure.

[0006] Beneficial effects: The installation structure of this utility model is applied to an air outlet device, which includes an ion generator.

When the ion generator has been used for a long time and the emitter head has accumulated a lot of dust, the user can remove the emitter head for cleaning or wiping to ensure that its ion emission efficiency meets the requirements, thereby achieving a better air purification effect. Moreover, the emitter head is located on the air inlet side of the air duct, where the wind speed is relatively high, which allows the ions generated by the ion generator to diffuse fully, improves the ion diffusion efficiency, and effectively increases the ion concentration in the air.

[0007] In one alternative embodiment, the mounting structure includes a mounting bracket and a knob assembly, with the transmitter head disposed on the side of the mounting bracket facing the air duct, and the knob assembly used to lock or unlock the mounting bracket from the air duct.

[0013] In one alternative embodiment, the first knob and the second knob are detachably connected by threads, and the rotational friction between the first knob and the second knob is greater than the rotational force of the first knob or the second knob engaging or disengaging from the engaging protrusion.

[0014] Beneficial effects: The installation structure of this utility model allows for a detachable connection between the first and second knobs via threads, facilitating their installation. Furthermore, since the rotational friction between the first and second knobs is greater than the rotational force exerted by the locking or disengaging protrusions, the first and second knobs will not become loose when the user operates the knob assembly to assemble or disassemble the ion generator emitter head.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0046] Currently, fans with air purification functions typically place their negative ion generators at the central hub behind the fan blades. While this layout can produce a certain number of negative ions (approximately 1-2 million), the diffusion efficiency is low due to the limited airflow distribution within the duct, resulting in limited air purification effects. Furthermore, over long-term use, the ion generator's emitter head easily attracts dust, reducing emission efficiency and even causing the generator to completely fail, thus compromising air purification efficiency and effectiveness.

[0047] Based on this, the present invention provides an installation structure and air outlet device with high ion diffusion efficiency and good air purification effect.

[0048] The following is combined with Figures 1-8 This describes an embodiment of the installation structure and air outlet device of this utility model.

[0049] According to an embodiment of the present invention, in a first aspect, an installation structure is provided for use in an air outlet device. The air outlet device includes an air duct 1 and an ion generator. The ion generator includes an emitter 201, which is detachably connected to the air inlet side of the air duct 1 via the installation structure.

[0050] This installation structure is applied to the air outlet device. The emitter head 201 of the ion generator in the air outlet device is detachably connected to the air inlet side of the air duct 1 through this installation structure. When the ion generator is used for a long time and the emitter head 201 of the ion generator has accumulated a lot of dust, the user can remove the emitter head 201 for cleaning or wiping to ensure that its ion emission efficiency meets the requirements, thereby achieving a better air purification effect. Moreover, the emitter head 201 is set on the air inlet side of the air duct 1, where the wind speed is high, which can make the ions generated by the ion generator fully diffuse, improve the ion diffusion efficiency, and effectively increase the ion concentration in the air.

[0051] like Figure 1 As shown, the installation structure of this embodiment is applied to an air outlet device, such as a fan. The air outlet device includes a housing 10, an air duct 1, and an ion generator. The air duct 1 is disposed within the housing 10. The air inlet side of the air duct 1 has an air inlet 6, and the air outlet side of the air duct 1 has an air outlet 7. The design of the air inlet 6 needs to ensure sufficient air intake area so that airflow can smoothly enter the air duct 1. The ion generator is disposed in the air duct 1. In this embodiment, the ion generator is specifically a negative ion generator. This negative ion generator can release negative ions to neutralize positive ion particles (such as dust, bacteria, etc.) in the air, causing them to settle, thereby reducing pollutants in the air and achieving the effect of purifying the air.

[0052] The ion generator includes an emitter head 201. In this embodiment, two emitters head 201 are provided. The emitter head 201 is detachably connected to the air inlet side of the air duct 1 through the installation structure of this embodiment. When it is necessary to clean the emitter head 201, the emitter head 201 can be removed from the air inlet side of the air duct 1. After cleaning, the emitter head 201 can be installed back onto the air inlet side of the air duct 1. The operation is simple and can ensure that the ion emission efficiency of the ion generator meets the usage requirements, making it convenient for users.

[0053] Furthermore, the mounting structure includes a mounting bracket 3 and a knob assembly. The transmitter head 201 is located on the side of the mounting bracket 3 facing the air duct 1, and the knob assembly is used to lock or unlock the mounting bracket 3 from the air duct 1.

[0054] like Figures 2-3 As shown, the installation structure includes a mounting bracket 3 and a knob assembly. The mounting bracket 3 is located on the outside of the air duct 1, and the emitter 201 is located on the side of the mounting bracket 3 facing the air duct 1, so that the emitter 201 can approach the air duct 1 and release negative ions. The knob assembly is used to lock or unlock the mounting bracket 3 from the air duct 1.

[0055] In this embodiment, the side wall of the air duct 1 is formed with an emitter mounting hole, through which the emitter 201 passes and is placed inside the air duct 1. When the mounting bracket 3 is locked to the air duct 1, the emitter 201 is inserted into the emitter mounting hole in the side wall of the air duct 1 and placed inside the air duct 1, enabling it to release negative ions inside the air duct 1. When the mounting bracket 3 is unlocked from the air duct 1, the emitter 201 can be removed from the air duct 1 along with the mounting bracket 3 for cleaning.

[0056] The emitter mounting hole on the side wall of the air duct 1 is located on the air inlet side of the air duct 1. After the emitter 201 is inserted into the emitter mounting hole, it can release negative ions on the air inlet side of the air duct 1. The air velocity on the air inlet side of the air duct 1 is relatively high, which enables the negative ions generated by the ion generator to be quickly carried out by the high-speed airflow and achieve full diffusion of negative ions, thereby improving the diffusion efficiency of negative ions and effectively increasing the concentration of negative ions in the air, thus improving the air purification effect.

[0057] Furthermore, the knob assembly includes a first knob 401 and a second knob 402, which are connected and rotate synchronously. One of the first knob 401 and the second knob 402 is located on the side of the mounting bracket 3 facing away from the air duct 1, and the other is located on the side of the mounting bracket 3 facing the air duct 1.

[0058] like Figures 2-3 As shown, the knob assembly includes a first knob component 401 and a second knob component 402. The first knob component 401 and the second knob component 402 are capable of rotating synchronously around their respective axes. In this embodiment, the first knob component 401 and the second knob component 402 are coaxially arranged. The first knob component 401 and the second knob component 402 can be integrally connected or detachably connected. The first knob component 401 and the second knob component 402 lock or unlock the mounting bracket 3 and the air duct 1 by rotation.

[0059] One of the first knob 401 and the second knob 402 is disposed on the side of the mounting bracket 3 facing away from the air duct 1, and the other is disposed on the side of the mounting bracket 3 facing the air duct 1. In this embodiment, the second knob 402 is disposed on the side of the mounting bracket 3 facing away from the air duct 1, and the first knob 401 is disposed on the side of the mounting bracket 3 facing the air duct 1. A lever position 4021 is provided on the outer side of the second knob 402 to facilitate user hand operation. By operating the lever position 4021, the user can drive the first knob 401 and the second knob 402 to rotate around the axial direction, thereby locking or unlocking the mounting bracket 3 and the air duct 1.

[0060] In other embodiments, depending on different setup requirements, the first knob 401 can be located on the side of the mounting bracket 3 facing away from the air duct 1, and the second knob 402 can be located on the side of the mounting bracket 3 facing the air duct 1. A lever position is provided on the outer side of the first knob 401. As long as the first knob 401 and the second knob 402 can be manually rotated to lock or unlock the mounting bracket 3 and the air duct 1, it is acceptable.

[0061] Furthermore, the installation structure also includes a duct mounting hole 101, which is located on the side wall of the duct 1. The inner wall of the duct mounting hole 101 is provided with at least two snap-fit ​​protrusions 102. The first knob 401 or the second knob 402 can be axially snapped or disengaged from the snap-fit ​​protrusions 102 by rotation.

[0062] like Figures 5-6 As shown, the installation structure also includes a duct mounting hole 101, which is located in the duct 1. The duct mounting hole 101 is located near the emitter mounting hole on the side wall of the duct 1. The knob assembly is matched and installed with the duct mounting hole 101. When the emitter 201 of the ion generator is inserted into the emitter mounting hole, the knob assembly can be docked with the duct mounting hole 101 to lock the mounting bracket 3 to the duct 1.

[0063] The duct mounting hole 101 is a through hole, and at least two engaging protrusions 102 are provided on the inner wall of the duct mounting hole 101. The engaging protrusions 102 protrude towards the center of the duct mounting hole 101 and protrude beyond the inner wall of the duct mounting hole 101. In this embodiment, two engaging protrusions 102 are provided, and the two engaging protrusions 102 are arranged opposite each other to facilitate the secure engagement of the knob assembly and improve the reliability and stability of the structural connection.

[0064] The first knob 401 or the second knob 402 can be axially engaged or disengaged from the locking protrusion 102 by rotation. In this embodiment, the first knob 401 is located on the side of the mounting bracket 3 facing the air duct 1. Therefore, the first knob 401 can be axially engaged or disengaged from the locking protrusion 102 by rotation. When the first knob 401 is engaged with the locking protrusion 102 by rotation, the first knob 401 cannot disengage from the air duct mounting hole 101 along its axial direction, and the mounting bracket 3 is locked to the air duct 1. When the first knob 401 disengages from the locking protrusion 102 by rotation, the first knob 401 can disengage from the air duct mounting hole 101 along its axial direction, and the mounting bracket 3 is unlocked from the air duct 1. This detachable mounting structure of the mounting bracket 3 and the air duct 1 is easy to operate, highly reliable, and structurally robust and stable.

[0065] Specifically, a buckle 4011 is provided at one end of the first knob 401 that is inserted into the air duct mounting hole 101, and the buckle 4011 protrudes outward in a direction away from the center of the first knob 401. Optionally, the number of buckles 4011 is the same as the number of snap-fit ​​protrusions 102, and the positions of the buckles 4011 correspond to the positions of the snap-fit ​​protrusions 102.

[0066] During installation, the end of the first knob 401 with the buckle 4011 is inserted into the duct mounting hole 101 and passes over the locking protrusion 102, so that the buckle 4011 is located inside the locking protrusion 102. Rotating the second knob 402 and the first knob 401 causes the buckle 4011 to engage with the locking protrusion 102, preventing the first knob 401 from disengaging from the duct mounting hole 101 axially. At this point, the mounting bracket 3 is locked to the duct 1. During disassembly, rotating the second knob 402 and the first knob 401 causes the buckle 4011 to disengage from the locking protrusion 102, allowing the first knob 401 to disengage from the duct mounting hole 101 axially, thus unlocking the mounting bracket 3 from the duct 1.

[0067] In other embodiments, the number of snap-fit ​​protrusions 102 may be three, four, five, etc., and correspondingly, the number of swivel buckles 4011 may also be three, four, five, etc.

[0068] In other embodiments, if the second knob 402 is located on the side of the mounting bracket 3 facing the air duct 1, the second knob 402 can be axially engaged or disengaged from the engaging protrusion 102 by rotation.

[0069] Furthermore, the first knob 401 and the second knob 402 are detachably connected by threads, and the rotational friction between the first knob 401 and the second knob 402 is greater than the rotational force of the first knob 401 or the second knob 402 engaging or disengaging from the engaging protrusion 102.

[0070] In this embodiment, the first knob 401 and the second knob 402 are detachably connected, so that the first knob 401 and the second knob 402 can be disassembled as needed to facilitate the installation of the mounting bracket 3, the first knob 401 and the second knob 402, and to facilitate installation and operation.

[0071] Specifically, the second knob 402 has a threaded hole formed at one end facing the first knob 401, and a portion of the outer wall of the first knob 401 has an external thread. The portion of the first knob 401 with the external thread is adapted to be screwed into the threaded hole, thereby achieving the connection between the first knob 401 and the second knob 402.

[0072] When disassembling and assembling bracket 3, it is necessary to rotate the first knob 401 and the second knob 402. The rotational friction between the first knob 401 and the second knob 402 is greater than the rotational force of the first knob 401 or the second knob 402 engaging or disengaging from the engaging protrusion 102. This ensures that when the first knob 401 and the second knob 402 are rotated, they will not loosen or disengage. This allows the first knob 401 and the second knob 402 to rotate synchronously without relative rotation, thereby improving the reliability of the structure.

[0073] This embodiment also provides an air outlet device, including an air duct 1, an ion generator, and an installation structure as described above. The ion generator is disposed on the air inlet side of the air duct 1, and the emitter head 201 of the ion generator is detachably connected to the air duct 1 through the installation structure.

[0074] The air outlet device can blow out ambient temperature air to provide cooling for users. In this embodiment, the air outlet device is a fan.

[0075] The fan comprises a head section and a support rod section, with the head section positioned atop the support rod section. The head section includes a housing 10, an air duct 1, and an ion generator. The air duct 1 is located inside the housing 10, and the ion generator is positioned on the air inlet side of the air duct 1. This location provides a higher airflow velocity, allowing for sufficient diffusion of the ions generated by the ion generator, improving ion diffusion efficiency, and effectively increasing the ion concentration in the air. The ion generator's emitter head 201 is detachably connected to the air duct 1 via the mounting structure of this embodiment. When the ion generator has been used for a long time and the emitter head 201 accumulates a lot of dust, the user can remove the emitter head 201 for cleaning or wiping to ensure its ion emission efficiency meets requirements, thereby achieving better air purification results.

[0076] The air outlet device also has a control module, which controls the overall operation of the air outlet device and is electrically connected to the ion generator. Of course, this air outlet device also has other structural components that are present in existing fans, such as fan blades and motors that drive the fan blades to rotate, which will not be described in detail here.

[0077] To achieve a more uniform appearance for the fan head section, after the mounting bracket 3 is locked and installed with the air duct 1, the mounting bracket 3 is flush with the surface of the housing 10, forming a single integrated structure. This results in no noticeable difference in appearance, making the structure of the fan head section more regular and uniform, and improving the product's aesthetics. In this embodiment, the mounting bracket 3 is located at the bottom of the fan head section, i.e., the bottom of the housing 10.

[0078] In this embodiment, the ion generator includes an ion generator body 202 and an emitter head 201, which are electrically connected. The ion generator has a power cord 203 for connection to a power supply.

[0079] like Figure 4 As shown, the ion generator body 202 is mounted on the outer wall of the air duct 1. The outer wall of the air duct 1 is provided with a body positioning post 8 and screw holes. The ion generator body 202 is correspondingly provided with positioning holes and assembly holes. The positioning holes on the ion generator body 202 can be inserted into the body positioning post 8 to achieve positioning of the ion generator body 202. The assembly holes on the ion generator body 202 cooperate with the screw holes, and the ion generator body 202 is installed on the outer wall of the air duct 1 by screws 9.

[0080] Furthermore, the air outlet device also includes an ion concentration detection element 5, which is installed in the air duct 1 and is used to detect the ion concentration inside the air duct 1.

[0081] The ion concentration detection element 5 is specifically an ion concentration detector. The ion concentration detection element 5 is disposed in the air duct 1 and can detect the ion concentration inside the air duct 1. In this embodiment, the ion concentration detection element 5 is used to detect the negative ion concentration inside the air duct 1.

[0082] The ion concentration detector 5 is electrically connected to the control module. After long-term use of the air outlet device, dust accumulates around the emitter head 201 of the ion generator, affecting the emission efficiency. The ion concentration detector 5 can detect the negative ion concentration in real time. When the negative ion concentration value is lower than the preset value, it transmits a signal to the control module. The control module issues a reminder command, prompting the user that the emitter head 201 of the ion generator is heavily dusty and needs to be cleaned.

[0083] Furthermore, in the axial direction of the air duct 1, the ion concentration detection element 5 is arranged collinearly with the emitter head 201.

[0084] After the ion generator emitter 201 releases ions, they flow along the axial direction of the air duct 1 towards the air outlet 7 under the action of airflow. The ion concentration detection element 5 is set collinearly with the emitter 201 in the axial direction of the air duct 1, which can detect the ion concentration more directly and accurately, and can collect the negative ions generated by the emitter 201 to the maximum extent. It can also detect fluctuations in the negative ion concentration, thus improving the detection accuracy.

[0085] In this embodiment, the ion concentration detector 5 is positioned close to the air outlet 7, which ensures detection accuracy while making full use of the space and improving space utilization.

[0086] In other embodiments, multiple ion generators can be provided, and these multiple ion generators are arranged at intervals along the circumference of the air duct 1 to form a superimposed effect, maximizing the concentration of negative ions and achieving the best purification effect. For example, two or three ion generators can be provided.

[0087] The disassembly and assembly process of the ion generator emitter head 201 in the air outlet device of this embodiment will be described below with reference to the accompanying drawings:

[0088] After the air outlet device starts working, the motor drives the fan blades to rotate and form airflow. The ion generator starts working and the emitter 201 in the air duct 1 releases negative ions. The negative ions flow towards the air outlet 7 with the high-speed airflow. At the same time, the ion concentration detector 5 detects the concentration of negative ions in the air duct 1 in real time.

[0089] When the ion generator has been used for a long time, the emitter head 201 will accumulate a lot of dust. The ion concentration detector 5 will detect that the negative ion concentration in the air duct 1 is lower than the preset value. At this time, the control module will issue a command to remind the user to clean the emitter head 201.

[0090] At this time, the user manually operates the lever position 4021, causing the first knob 401 and the second knob 402 to change from... Figure 6 Position rotated to Figure 5 Positioning: The clasp 4011 disengages from the locking protrusion 102, unlocking the mounting bracket 3 from the air duct 1. At this point, the mounting bracket 3 can be removed to clean the transmitter 201. After cleaning, align the transmitter 201 with the transmitter mounting hole on the air duct 1, and insert the first knob 401 into the air duct mounting hole 101, causing the first knob 401 and the second knob 402 to... Figure 5 Position rotated to Figure 6 Position, the swivel 4011 engages with the snap-fit ​​protrusion 102, the mounting bracket 3 locks with the air duct 1, completing the installation of the mounting bracket 3 and the transmitter head 201.

[0091] like Figure 7 and Figure 8 As shown, compared to traditional air outlet devices where the ion generator emitter is installed at the center hub behind the fan blades, the ion generator in this embodiment is installed on the air inlet side of the air duct 1. Fluid simulation results show that the average wind speed near the emitter installation location in traditional air outlet devices is around 2.3 m / s, while in this embodiment it is around 5.7 m / s, representing a significant increase in wind speed. This optimizes the diffusion efficiency of negative ions and significantly increases their concentration, reaching an average of over 3 million ions in actual tests, thus achieving a better air purification effect.

[0092] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
