Detailed Implementation

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] This application provides an air outlet assembly for a handheld fan. By integrating the spray component and the display on the base in the middle of the air outlet grille, the components that realize the display function and the components that realize the spray function are integrated in the same position of the handheld fan, thereby making the arrangement of the components in the handheld fan compact, thus effectively reducing the size of the handheld fan and facilitating the miniaturization of the handheld fan.

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0029] Please see Figures 1 to 3 This application provides an air outlet assembly 100, which includes an air outlet grille 110, a spray element 120, and a display 130.

[0030] The air outlet grille 110 can control the airflow direction and achieve directional air delivery. Specifically, the air outlet grille 110 includes a base 111, an annular body 112 surrounding the base 111, and multiple air guide ribs 113 connecting the outer periphery of the base 111 and the inner periphery of the annular body 112. The multiple air guide ribs 113 are arranged sequentially at intervals along the circumference of the base 111. In this document, "multiple" refers to at least two. Alternatively, only one air guide rib 113 may be provided.

[0031] In this embodiment, the base 111, the ring 112, and the multiple air guide ribs 113 are integrally formed. This facilitates the processing and forming of the air outlet grille 110 and enhances its structural strength. The integral forming method can be injection molding, 3D printing, or other integral forming methods. In other embodiments, the base 111, the ring 112, and the multiple air guide ribs 113 can also be fixed by bonding, ultrasonic welding, or other fixed methods, or by detachable methods such as snap-fit, buckle, tenon and mortise, magnetic connection, and screw connection. No specific limitation is made here.

[0032] The spray element 120 and the display 130 are integrated on the base 111. The spray element 120 is used to spray air onto the air outlet side of the air outlet grille 110. The spray direction can be set directly in the horizontal direction, or it can be set tilted upward, tilted downward, tilted to the left, or tilted to the right. The display 130 is used to display relevant data of the handheld fan 1000. The content displayed on the display 130 includes, but is not limited to, one or more of the following: wind speed level, blowing mode, spray level, spray mode, power status, water status, fan speed, time information, temperature information (such as ambient temperature, air outlet temperature, and other temperatures), and fault codes.

[0033] The installation methods for the spray unit 120 and the display 130 are set according to the fixed connection method or the detachable connection method described above, and will not be repeated here. Alternatively, an additional mounting bracket can be provided. First, the spray unit 120 and the display 130 are mounted on the mounting bracket, and then the mounting bracket is mounted on the base 111 in the detachable manner described above, thus completing the installation of the spray unit 120 and the display 130.

[0034] The number of sprayers 120 and the number of displays 130 can be one or more. When there are multiple sprayers 120, the spraying direction of each sprayer 120 can be the same or different. When there are multiple displays 130, the content displayed by each display 130 can be the same or different. The number of sprayers 120 and the number of displays 130 can be the same or different. In addition, the sprayers 120 and the displays 130 can be set up one-to-one, one-to-many, or many-to-one. Figure 3 The diagram illustrates a scenario where both the spray nozzle 120 and the display 130 are configured as a single unit.

[0035] In this embodiment, the spray element 120 and the display 130 are integrated inside the base 111. This design allows the base 111 to protect the spray element 120 and the display 130 in the event of an accidental drop of the handheld fan 1000, effectively preventing them from being damaged by direct impact. In other embodiments, the spray element 120 and the display 130 can also be integrated outside the base 111. This eliminates the need for internal installation space within the base 111, making installation of the spray element 120 and the display 130 easier. For example, the lower part of the outer peripheral wall of the base 111 may have an insertion port into which the spray element 120 is inserted, and the display 130 is installed on the air outlet side of the base 111. Alternatively, both the display 130 and the spray element 120 may be semi-circular, with the display 130 installed on the upper half of the air outlet side of the base 111 and the spray element 120 installed on the lower half of the air outlet side of the base 111.

[0036] It is worth mentioning that, considering that the sprayer 120 will produce slight vibrations during the spraying process, if the sprayer 120 directly contacts the display 130, the slight vibrations of the sprayer 120 will be transmitted to the display 130, causing the display 130 to vibrate. Therefore, in order to avoid the display 130 vibrating due to direct contact with the sprayer 120, in this embodiment, there is a gap between the sprayer 120 and the display 130.

[0037] Through the above technical solution, by means of the air outlet grille 110 including a base 111 and an annulus 112 surrounding the base 111, the outer periphery of the base 111 and the inner periphery of the annulus 112 being connected by air guide ribs 113, and the spray component 120 and display 130 being integrated into the base 111, the components that realize the display function and the components that realize the spray function are integrated in the same position of the air outlet grille 110, thereby making the arrangement of components in the handheld fan 1000 compact and occupying less space, thus effectively reducing the size of the handheld fan 1000 and facilitating the miniaturization of the handheld fan 1000.

[0038] Please see Figure 3 and Figure 4There are many ways to integrate the spray element 120 and the display 130 onto the base 111. In one embodiment of this application, the air outlet side of the base 111 is provided with a mounting groove 1111, and the spray element 120 and the display 130 are integrated into the mounting groove 1111. This arrangement makes the opening of the mounting groove 1111 located on the air outlet side of the base 111, so that the spray element 120 and the display 130 can be installed through the outside of the base 111, thereby facilitating the installation of the mist spray element 120 and the display 130.

[0039] By way of example and not limitation, the sprayer 120 and the display 130 may both not extend beyond the opening of the mounting slot 1111, or the sprayer 120 and the display 130 may both partially extend beyond the opening of the mounting slot 1111, or the sprayer 120 may partially extend beyond the opening of the mounting slot 1111 while the display 130 does not extend beyond the opening of the mounting slot 1111.

[0040] In addition, in this embodiment, the shape of the mounting groove 1111 is adapted to the shape of the base 111 and both are circular, which makes the space of the mounting groove 1111 large enough to facilitate the installation of the sprayer 120 and the display 130. In other embodiments, the mounting groove 1111 may also be annular or racetrack-shaped.

[0041] In other embodiments, the air outlet grille 110 may also be configured to include two parts arranged in half along its radial direction, the two parts of the air outlet grille 110 being detachably connected. Correspondingly, the base 111 also includes two parts arranged in half along its radial direction, the two parts of the base 111 surrounding to form a mounting cavity, and the spray element 120 and the display 130 are mounted in the mounting cavity, thus enabling the spray element 120 and the display 130 to be integrated into the mounting cavity.

[0042] In some embodiments, a partition plate (not shown) is provided between the two opposite sides of the inner peripheral wall of the mounting groove 1111. The partition plate is also sealed to the bottom of the mounting groove 1111 to divide the mounting groove 1111 into two independent spaces. The display 130 is installed in one space, and the sprayer 120 is installed in the other space. This arrangement can effectively prevent the water mist generated by the sprayer 120 during the spraying process from escaping into the display 130, thereby avoiding safety hazards caused by water mist adhering to the display 130. Of course, in other embodiments, two independent grooves (not shown) can be provided on the air outlet side of the base 111, with the sprayer 120 and the display 130 installed in the two grooves respectively. This can achieve the same effect as the partition plate provided in the mounting groove 1111 described above.

[0043] Further, please refer to Figure 2 and Figure 3 The air outlet assembly 100 also includes a display panel 140, which is detachably connected to the base 111 and covers the opening of the mounting groove 1111. The display panel 140 is partially through-hole, and the spray nozzle of the spray component 120 is located in the through-hole portion of the display panel 140. The way in which the display panel 140 and the base 111 are detachably connected is set with reference to the detachable connection method in the above embodiment, and will not be described in detail here.

[0044] By way of example and not limitation, the display panel 140 may be a transparent panel, so that the content displayed on the monitor 130 can be displayed through the display panel 140; the display panel 140 may also be a transparent panel covered with a semi-transparent film, the color of which may be black, blue or other colors; the display panel 140 may also include two parts, a transparent area and a non-transparent area, with the transparent area facing the monitor 130 and the non-transparent area facing the sprayer 120.

[0045] There are many ways to integrate the aforementioned spray component 120 and display 130 into the mounting slot 1111; please refer to [link / reference]. Figure 1 , Figure 3 as well as Figure 4 In one embodiment of this application, the spray end of the spraying component 120 and the display 130 are both arranged adjacent to the opening of the mounting groove 1111, and the spraying end of the spraying component 120 is located within the space formed by the outer peripheral wall of the display 130 and the inner peripheral wall of the mounting groove 1111. This arrangement not only makes the arrangement of the spraying component 120 and the display 130 more compact, but also provides sufficient space between the rear side of the display 130 and the bottom wall of the mounting groove 1111 for the passage of wires.

[0046] Specifically, please refer to Figure 1 The inner peripheral wall of the mounting groove 1111 is provided with a plurality of support ribs 1112 arranged at intervals along its circumference. Each support rib 1112 extends from the groove opening to the bottom of the mounting groove 1111. The rear side of the display 130 abuts against the end of each support rib 1112 near the groove opening of the mounting groove 1111, thus facilitating the arrangement of the display 130 adjacent to the groove opening of the mounting groove 1111.

[0047] Furthermore, the outer peripheral wall of the display 130 includes a first segment (unmarked) and a second segment (unmarked) connected end to end. The spray tip of the sprayer 120 is located within the space formed by the first segment and the inner peripheral wall of the mounting groove 1111. The second segment is adjacent to the inner peripheral wall of the mounting groove 1111, and the shape of the second segment matches the shape of the inner peripheral wall of the mounting groove 1111, both being arc-shaped. This expands the display area of ​​the display 130. The second segment can be a superior arc shape, a inferior arc shape, or a semi-circular arc shape; no specific limitation is made here.

[0048] In other embodiments, the spray element 120 may be disposed at the center of the mounting groove 1111, the display 130 may be annular with its inner peripheral wall surrounding the spray element 120, and the outer peripheral wall of the display 130 may be adjacent to the inner peripheral wall of the mounting groove 1111, thus enabling the spray element 120 and the display 130 to be integrated into the mounting groove 1111.

[0049] There are many ways in which the spray tip of the aforementioned spray component 120 is located within the space formed by the inner peripheral wall of the display 130 and the mounting groove 1111. Please refer to [link / reference]. Figure 1 , Figure 3 as well as Figure 4 In one embodiment of this application, a receiving notch 131 is formed on the outer periphery of the display 130, and the spraying end of the spraying member 120 is located within the space formed by the receiving notch 131 and the inner peripheral wall of the mounting groove 1111. This arrangement allows the display 130 to almost completely fill the opening of the mounting groove 1111, thereby maximizing the display area of ​​the display 130. Obviously, the receiving notch 131 is formed as the first segment described above.

[0050] In this embodiment, the outer peripheral wall of the spray element 120 is adjacent to the inner peripheral wall of the receiving notch 131, and the shape of the outer peripheral wall of the spray element 120 matches the shape of the inner peripheral wall of the receiving notch 131, thereby further expanding the display area of ​​the display 130. In this embodiment, both the outer peripheral wall of the spray element 120 and the inner peripheral wall of the receiving notch 131 are arc-shaped. In other embodiments, both the outer peripheral wall of the spray element 120 and the inner peripheral wall of the receiving notch 131 may be zigzag-shaped.

[0051] There are many ways in which the spray tip of the aforementioned spray component 120 is located within the space formed by the inner peripheral wall of the display 130 and the mounting groove 1111. Please refer to [link / reference]. Figure 5In another embodiment of this application, a straight segment 132 is formed on the outer periphery of the display 130. The spraying end of the spraying member 120 is located within the space formed by the straight segment 132 and the inner peripheral wall of the mounting groove 1111. With this arrangement, the display 130 can be formed simply by additionally machining a straight segment 132 on the outer periphery of the display 130, making the machining of the display 130 convenient. Obviously, the straight segment 132 is formed as the first segment described above.

[0052] It is worth mentioning that when the display 130 is provided with a receiving notch 131 and one display 130 corresponds to multiple spraying elements 120, the receiving notch 131 is set to be multiple, and the spraying end of each spraying element 120 is located in the space formed by the corresponding receiving notch 131 and the inner peripheral wall of the mounting groove 1111. When the display 130 is provided with a straight line segment 132 and one display 130 corresponds to multiple spraying elements 120, the straight line segment 132 can be set to be multiple, and the spraying end of each spraying element 120 is located in the space formed by the corresponding straight line segment 132 and the inner peripheral wall of the mounting groove 1111. Alternatively, the straight line segment 132 can be set to be one, and multiple spraying elements 120 are located in the same space formed by the same straight line segment 132 and the inner peripheral wall of the mounting groove 1111.

[0053] There are many types of the aforementioned spray component 120; please refer to [link / reference]. Figure 1 In one embodiment of this application, the spraying component 120 is an atomizing nozzle. The air inlet and liquid inlet of the atomizing nozzle are respectively connected to an air pressure source (not shown) and a liquid source (not shown). This configuration enables the atomizing nozzle to spray a high-intensity mist over a long distance.

[0054] Specifically, the atomizing nozzle has a gas channel (not shown) and a liquid channel (not shown). The inlet end of the gas channel is connected to a pressure source, and the inlet end of the liquid channel is connected to a liquid source. The outlet of the gas channel and the outlet of the liquid channel intersect to form a mist outlet. When the pressure source is running, a high-pressure airflow is generated at the intersection of the outlet and the liquid outlet and sprayed towards the mist outlet. The intersection of the outlet and the liquid outlet creates a vacuum effect under the action of the high-pressure airflow. The vacuum effect creates a pressure difference, which causes the liquid in the liquid source to be drawn through the liquid channel to the intersection of the outlet and the liquid outlet for atomization. That is, when the liquid enters the intersection of the outlet and the liquid outlet, it is dispersed and atomized under the impact of the high-pressure airflow and sprayed outward from the mist outlet with the high-pressure airflow.

[0055] An air pressure source can generate high-pressure airflow. There are many types of air pressure sources. In this embodiment, the air pressure source is set as an air pump, which can directly generate high-pressure airflow, making the generation of high-pressure airflow convenient. In other embodiments, the air pressure source can also be set as a manual air-pressurization structure or other air pressure devices capable of generating high-speed airflow. The liquid source is used to store the liquid to be atomized, such as water, sunscreen, mosquito repellent, air freshener, and other types of liquids. There are many types of liquid sources, which can be liquid storage tanks, liquid storage containers, or other liquid storage structures.

[0056] Please see Figure 1 and Figure 3 In one embodiment of this application, the spray element 120 is offset from the axis of the base 111. This arrangement makes the spray element 120 close to the air outlet formed between the base 111 and the ring 112, thereby facilitating the spray mist sprayed by the spray element 120 to be carried by the blown wind and blown towards the user.

[0057] Please see Figures 1 to 3 This application also proposes a handheld fan 1000, which includes an air outlet component 100 and a fan body 200 as described above. The air outlet component 100 is disposed on the fan body 200. The specific structure of the air outlet component 100 is as described in the above embodiments. Since the handheld fan 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0058] In this embodiment, the fan body 200 includes a handheld part 210 and a fan part 220 connected to each other. An air outlet grille 110 is disposed on the fan part 220. The air outlet grille 110 can be a separate component and detachably mounted on the fan part 220, or it can be integrally formed with the fan part 220. The connection method between the handheld part 210 and the fan part 220 is set according to the fixed connection or detachable connection methods in the above embodiments, and will not be described in detail here. In other embodiments, the fan body 200 can also be a single integral component.

[0059] Furthermore, both the air pressure source and the liquid source are installed inside the handheld part 210. A guide rib 113 is located below the base 111 and has a connecting channel 1131. The connecting channel 1131 connects the interior of the base 111 and the outer periphery of the ring 112, thus facilitating the connection of the spray element 120 to the air pressure source and the liquid source after passing through the connecting channel 1131 via a pipe. In addition, the length of the guide rib 113 in the circumferential direction of the base 111 is equal to the width of the guide rib 113. The width of the guide rib 113 where the connecting channel 1131 is located is much larger than the width of the other guide ribs 113. This ensures that only the guide rib 113 where the connecting channel 1131 is located has a larger width, while the widths of the other guide ribs 113 are of conventional size. This ensures that adding a pipe channel to a guide rib 113 will not affect the air outlet effect of the air outlet grille 110. In addition, the handheld unit 210 also contains a control circuit board (not shown) and a battery. The control circuit board is electrically connected to the display, the air pressure source and the battery to control the display and the air pressure source.

[0060] Please see Figures 1 to 3 In one embodiment of this application, the spray element 120 is located below the display 130. This arrangement can shorten the distance between the spray element 120 and the air pressure source and liquid source in the handheld part 210, and make it easier to connect the spray element 120 and the air pressure source and the spray element 120 and the liquid source through the pipeline.

[0061] In other embodiments, the spray element 120 may also be located above the display 130, or on the left or right side of the display 130. Obviously, when multiple spray elements 120 are provided, the multiple spray elements 120 may be located on different sides of the display 130, or the multiple spray elements 120 may be located on the same side of the display 130.

[0062] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this application's specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the scope of patent protection of this application.
