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 a portable fan assembly in which an air pump and a battery are arranged in the handheld part along the front-to-back direction. On the one hand, the air pump can be used as a power source to realize the spraying function. The liquid can be drawn to the atomizing nozzle for atomization by utilizing the siphon principle generated by the air pump. On the other hand, the width of the handheld part in the left-to-right direction can be effectively reduced. Thus, it is possible to install an additional power source for the spraying function in the handheld part while effectively reducing the size of the handheld part, so as to make it convenient for the user to hold.

[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 Figure 1 and Figure 2This application provides a portable fan assembly 100, which includes a handheld part 10, an air pump 20, and a battery 30. The air pump 20 and the battery 30 are arranged in the handheld part 10 in a front-back direction.

[0030] The shape of the cross-section of the handheld part 10 can be various, including circular, elliptical, rhomboid, square, and other regular shapes, or other irregular shapes. No specific limitation is made here. Preferably, the cross-section of the handheld part 10 is elliptical, which allows the four corners of the outer periphery of the handheld part 10 to be rounded, making it easier for the user to grip.

[0031] There are many ways to form the handheld part 10. The handheld part 10 can be formed by one-piece molding such as injection molding or 3D printing. The handheld part 10 can also be set as two independent components and assembled by the two components. The two components can be fixed by ultrasonic welding, bonding or other fixed connection methods. The two components can also be fixed by detachable connection methods such as snap-fit, buckle 211 connection, magnetic connection or other methods. No specific limitation is made here.

[0032] The installation methods of the air pump 20 and battery 30 are set up according to the fixed connection or detachable connection methods described above, and will not be repeated here. The air pump 20 is the power source for the spraying function. Utilizing the siphon principle generated by the air pump 20, liquid is drawn to the atomizing nozzle (not shown) of the portable fan 1000 for atomization. The atomizing nozzle has a gas channel and a liquid channel. The liquid channel surrounds the gas channel. The air inlet of the gas channel is connected to the air pump 20, and the liquid inlet of the liquid channel is connected to the liquid source. The liquid outlet surrounds and is connected to the air outlet. Utilizing the siphon principle generated by the air pump 20, liquid at the liquid source is drawn to the liquid outlet for atomization. Obviously, the atomizing nozzle can be located on the handheld part 10, or on the fan part 200 (described below), or both the handheld part 10 and the fan part 200 can have atomizing nozzles.

[0033] The battery 30 provides the electrical energy required for the air pump 20 to operate. There are many types of batteries 30. The battery 30 can be a replaceable disposable battery 30 or a rechargeable battery 30. No specific limitation is made here.

[0034] In this embodiment, the air pump 20 is located in front of the battery 30. This arrangement shortens the distance between the air pump 20 and the atomizing nozzle located in front of the handheld part 10 or the fan part 200, thereby facilitating the connection of the air pump 20 and the air inlet of the atomizing nozzle via a pipeline. In other embodiments, the battery 30 may also be located in front of the air pump 20. Furthermore, the blowing end of the air pump 20 is located in front of the upper surface of the air pump 20, which further shortens the distance between the air pump 20 and the atomizing nozzle.

[0035] The number of air pumps 20 and batteries 30 can both be one or more; in this document, "multiple" refers to two or more. In this embodiment, the number of air pumps 20 and batteries 30 is set to one each. This arrangement ensures the basic functionality of the portable fan 1000 with a minimum number of components. In other embodiments, the number of air pumps 20 and batteries 30 can both be set to two, with the two air pumps 20 and two batteries 30 arranged parallel to each other in the left-right direction, and the two air pumps 20 located in front of the two batteries 30.

[0036] Preferably, the distance between the two sides of the air pump 20 in the left-right direction is greater than the distance between the two sides of the battery 30 in the left-right direction, so that the battery 30 and the inner wall of the handheld part 10 form a receiving space along the left-right direction, which facilitates the installation of other components. In addition, in other embodiments, the distance between the two sides of the air pump 20 in the left-right direction may be equal to the distance between the two sides of the battery 30 in the left-right direction, and the two sides of the air pump 20 in the left-right direction are correspondingly flush with the two sides of the battery 30 in the left-right direction; or the distance between the two sides of the air pump 20 in the left-right direction may be less than the distance between the two sides of the battery 30 in the left-right direction.

[0037] With the above technical solution, since the air pump 20 and battery 30 are arranged in the handheld part 10 along the front-back direction, the width of the handheld part 10 in the left-right direction can be effectively reduced. This achieves the purpose of effectively reducing the size of the handheld part 10 while installing an additional power source for spraying function in the handheld part 10, so as to make it convenient for the user to hold.

[0038] It is worth mentioning that, in some embodiments, the air pump 20 may have a recessed portion on one side facing the battery 30 to form an accommodating space, and the battery 30 may be partially located within this accommodating space. This allows the air pump 20 and the battery 30 to be partially staggered in the front-back direction, thereby reducing the length of the handheld part 10 in the front-back direction. Similarly, the battery 30 may also have a recessed portion on one side facing the air pump 20 to form an accommodating space, and the air pump 20 may be partially located within this accommodating space.

[0039] For easy installation of the air pump 20 and battery 30 into the handheld unit 10, please refer to... Figure 1 and Figure 2In one embodiment of this application, the handheld part 10 has a mounting cavity 101 with an upper opening. The air pump 20 and the battery 30 are arranged in the mounting cavity 101 in the front-back direction. With this arrangement, the air pump 20 and the battery 30 can be placed in the mounting cavity 101 through the upper opening and fixed accordingly, thus completing the installation of the air pump 20 and the battery 30. This makes it convenient to install the air pump 20 and the battery 30 into the handheld part 10.

[0040] In this design, the projection of the mounting cavity 101 from bottom to top coincides with the upper opening, thus allowing for unobstructed installation of components into the mounting cavity 101 through the upper opening, facilitating component installation. Furthermore, the cross-sectional shapes of both the upper opening and the mounting cavity 101 are adapted to the cross-sectional shape of the handle portion 10. The upper opening and mounting cavity 101 can be configured in a one-to-one or many-to-one manner, which will not be elaborated further here. In other embodiments, the mounting cavity 101 may be configured with an opening at the bottom and a sealed top.

[0041] Considering that if the mounting cavity 101 can be marked as two chambers 1011 connected in the front-back direction, with the air pump 20 and battery 30 respectively installed in the two chambers 1011, it would be possible to install the air pump 20 and battery 30 in the mounting cavity 101 in the front-back direction without adjusting their relative positions in the front-back direction. This would facilitate the arrangement of the air pump 20 and battery 30 in the mounting cavity 101 in the front-back direction. Therefore, please refer to... Figure 1 and Figure 2 In one embodiment of this application, both walls of the mounting cavity 101 in the left-right direction are provided with protrusions 102, and the mounting cavity 101 is divided into two chambers 1011 arranged sequentially in the front-back direction along the line connecting the two protrusions 102. The air pump 20 and the battery 30 are respectively arranged in the two chambers 1011. With this arrangement, the mounting cavity 101 can be marked as two chambers 1011 connected in the front-back direction by the arrangement of the two protrusions 102.

[0042] Specifically, both protrusions 102 extend vertically, and the lower end of each protrusion 102 is connected to the bottom wall of the mounting cavity 101, so that the two protrusions 102 can also enhance the structural strength of the handheld part 10.

[0043] Further, please refer to Figure 1 and Figure 2The protrusion 102 includes a first part 1021 and a second part 1022 connected in the front-back direction. The side of the first part 1021 facing away from the second part 1022 is connected to the cavity wall of the mounting cavity 101. The first part 1021 is flat and the second part 1022 is semi-cylindrical. Both the first part 1021 and the second part 1022 extend in the vertical direction and are connected to the bottom wall of the mounting cavity 101, which can further enhance the structural strength of the handheld part 10.

[0044] In this embodiment, the air pump 20 is located in the front chamber 1011 of the two chambers 1011, and the battery 30 is located in the rear chamber 1011 of the two chambers 1011. This achieves the arrangement described above where the air pump 20 is located in front of the battery 30. In other embodiments, the battery 30 may be located in the front chamber 1011 of the two chambers 1011, and the air pump 20 may be located in the rear chamber 1011 of the two chambers 1011.

[0045] To accommodate the larger air pump 20 or battery 30, please refer to Figure 1 and Figure 3 In one embodiment of this application, the bottom of the mounting cavity 101 is stepped and has two chambers 1011 arranged sequentially in the front-back direction. The depth of one chamber 1011 is greater than the depth of the other chamber 1011. The depth refers to the length along the vertical direction. The air pump 20 and the battery 30 are located in the two chambers 1011 respectively. With this arrangement, the air pump 20 or battery 30 can be accommodated in the deeper chamber of the two chambers 1011, thus accommodating the larger air pump 20 or battery 30.

[0046] In this embodiment, the depth of the rear chamber 1011 of the two chambers 1011 is greater than the depth of the front chamber 1011. The battery 30 is located in the rear chamber 1011, and the air pump 20 is located in the front chamber 1011. This allows for the accommodation of a larger battery 30, i.e., a battery with a larger capacity, thereby improving the battery life. In other embodiments, the depth of the rear chamber 1011 of the two chambers 1011 may be less than the depth of the front chamber 1011, with the battery 30 located in the rear chamber 1011 and the air pump 20 located in the front chamber 1011.

[0047] To provide the necessary mounting space for circuit board 40, please refer to [link / reference]. Figure 1 and Figure 2In one embodiment of this application, the portable fan assembly 100 further includes a circuit board 40. The circuit board 40 is electrically connected to both the air pump 20 and the battery 30. The circuit board 40 is located within the space formed by the battery 30 and the mounting cavity 101 in the left-right direction, thus creating the necessary mounting space for the circuit board 40. The mounting method of the circuit board 40 is the same as the fixed connection or detachable connection method described in the above embodiments, which will not be elaborated further here.

[0048] Furthermore, the outer periphery of the air pump 20, the outer periphery of the battery 30, and the outer periphery of the circuit board 40 are all spaced apart from the cavity wall of the mounting cavity 101, and the air pump 20, battery 30, and circuit board 40 are all spaced apart, which can enhance the heat dissipation effect of the air pump 20, battery 30, and circuit board 40.

[0049] For easy storage of the liquid required for spraying, please refer to [link / reference]. Figure 1 and Figure 3 In one embodiment of this application, the handheld part 10 further includes a liquid storage chamber 103 located below the mounting cavity 101. The liquid storage chamber 103 is connected to a liquid outlet pipe 104. The liquid outlet end of the liquid outlet pipe 104 is connected to the liquid inlet end of the atomizing nozzle via a pipe. The liquid outlet pipe 104 is located inside the mounting cavity 101 and beside the battery 30, thus allowing the liquid storage chamber 103 to store the liquid required for spraying. Furthermore, the liquid outlet pipe 104 can carry away the heat generated inside the mounting cavity 101 by the air pump 20, the battery 30, and the circuit board 40 when liquid passes through it, enhancing the heat dissipation effect of the handheld part 10.

[0050] Obviously, the liquid outlet pipe 104 can also be configured to contact the outer peripheral wall of at least one of the air pump 20 and the battery 30. This facilitates the conduction of heat generated by the air pump 20 and the battery 30 to the liquid outlet pipe 104, further enhancing the heat dissipation effect of the handheld part 10. Specifically, the liquid outlet pipe 104 is located within the space formed by the air pump 20, the battery 30, and the circuit board 40 within the mounting cavity 101. This configuration allows for a compact layout of the components within the handheld part 10, reducing the size of the handheld part 10 and facilitating its miniaturization.

[0051] Specifically, the mounting cavity 101, the liquid storage cavity 103, and the liquid outlet pipe 104 are all integrally formed by the handle part 10, which ensures the sealing of the mounting cavity 101, the liquid storage cavity 103, and the liquid outlet pipe 104. Furthermore, the shape of the upper cavity wall of the liquid storage cavity 103 is adapted to the shape of the lower cavity wall of the mounting cavity 101, forming a stepped arrangement. This ensures that the distance between any position on the upper cavity wall of the liquid storage cavity 103 and the corresponding position on the lower cavity wall of the mounting cavity 101 is equal, thereby improving the space utilization rate within the handle part 10.

[0052] For easy connection of the outlet pipe 104 and the inlet end of the atomizing nozzle via an external pipeline, please refer to [link / reference needed]. Figure 1 In one embodiment of this application, the outer peripheral wall of the battery 30 is provided with a relief recess 301. The relief recess 301 is located next to the liquid outlet of the liquid outlet pipe 104. With this arrangement, the distance between the liquid outlet of the liquid outlet pipe 104 and the battery 30 can be increased by the relief recess 301, which makes it easier to connect the external pipeline to the liquid outlet of the liquid outlet pipe 104 and the liquid inlet of the atomizing nozzle.

[0053] Obviously, the clearance recess 301 can be located at the upper end of the outer peripheral wall of the battery 30, and correspondingly, the upper end of the liquid outlet pipe 104 extends into the upper space of the mounting cavity 101 and is located beside the clearance recess 301; the clearance recess 301 can also be located at the lower end of the outer peripheral wall of the battery 30, and correspondingly, the liquid outlet pipe 104 is located in the lower space of the mounting cavity 101 and is located beside the clearance recess 301.

[0054] Further, please refer to Figure 1 and Figure 4 The battery 30 has clearance recesses 301 on both the upper and lower sides of the same side of its outer peripheral wall. This design serves to prevent accidental installation, ensuring that the clearance recesses 301 are exposed on both the upper and lower sides of the outer peripheral wall of the battery 30 when either side of the battery 30 is facing downwards along its length. Furthermore, the outer peripheral wall of the battery 30 protrudes, extending vertically, and the two clearance recesses 301 are formed at the upper and lower ends of this protruding portion, thereby increasing the capacity of the battery 30.

[0055] Please see Figure 1 In one embodiment of this application, the width of the handheld portion 10 in the left-right direction is less than the length of the handheld portion 10 in the front-back direction. Similarly, the width of the mounting cavity 101 in the left-right direction is less than the length of the mounting cavity 101 in the front-back direction. This facilitates the user's grip on the handheld portion 10 in the left-right direction. Optionally, the multiple of the length of the handheld portion 10 in the front-back direction to the width of the handheld portion 10 in the left-right direction is selected from any one of 1.2 times, 1.3 times, 1.4 times, 1.5 times, 1.6 times, or any two of these multiples.

[0056] Please see Figure 1 and Figure 5This application also provides a portable fan 1000, which includes the portable fan component 100 and a fan part 200 as described above. The fan part 200 is used to blow air to the user. The fan part 200 is connected to the handheld part 10. The fan part 200 and the handheld part 10 can be fixed by means of bonding, ultrasonic welding or other fixed connection. The fan part 200 and the handheld part 10 can also be fixed by means of detachable connection such as snap-fit, buckle 211 connection or magnetic connection. The fan part 200 and the handheld part 10 can also be partially integrally formed. The fan part 200 and the handheld part 10 can be one-to-one or many-to-one. No specific limitation is made here.

[0057] The specific structure of the component 100 of the portable fan is as described in the above embodiments. Since the portable 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] Further, please refer to Figure 1 and Figure 5 The air pump 20 and battery 30 can be clamped and fixed when the fan part 200 and the handheld part 10 are connected, thus enhancing the fixing strength of the air pump 20 and battery 30. Alternatively, in other embodiments, one of the air pump 20 and battery 30 can be clamped and fixed when the fan part 200 and the handheld part 10 are connected.

[0059] Specifically, please refer to [the relevant document / reference]. Figure 1 and Figure 6 The fan unit 200 is provided with a docking ring 210, which is inserted into the upper end of the inner peripheral wall of the mounting cavity 101 through the upper opening. The outer periphery of the docking ring 210 is provided with a buckle 211, and the inner peripheral wall of the mounting cavity 101 is provided with a fastening position (not shown) that cooperates with the buckle 211. This makes it easy to assemble and disassemble the fan unit 200 and the handheld unit 10.

[0060] 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.
