[0002] A portable fan is a type of fan that is easy to carry. It is usually small in size and lightweight, and can be easily put into a backpack, handbag or pocket, so that users can use it anytime and anywhere.

[0003] In the iterative innovation of portable fans, a portable fan that combines blowing and spraying functions has been designed. This type of portable fan is equipped with an atomizing nozzle, a housing, and a water pump. The water pump extends into the housing through an external transmission pipe, delivering the liquid inside the housing to the atomizing nozzle for atomization. However, since the transmission pipe extends directly into the housing, the joint between the transmission pipe and the housing has poor sealing. This makes it easy for the liquid inside the housing to leak out through the joint when there is shaking, so it urgently needs improvement. Utility Model Content

[0004] Therefore, it is necessary to provide a liquid storage tank for a portable fan to address the above problems. This tank is designed to effectively enhance the sealing of the connection between the transmission pipe and the tank body, so as to effectively prevent the liquid inside the tank from leaking out through the connection between the transmission pipe and the tank body when shaking occurs.

[0010] In one embodiment, the bottom wall of the liquid storage chamber has a first position and a second position, the first position being lower than the second position, and the inlet end of the transmission pipe being adjacent to the first position.

[0011] In one embodiment, the bottom wall of the liquid storage cavity is arranged in a concave conical shape.

[0012] In one embodiment, the bottom wall of the liquid storage chamber is provided with an injection port that can be opened or blocked, and the injection port is located beside the inlet end of the transmission pipeline.

[0013] In one embodiment, the transmission conduit is a rigid conduit.

[0014] This application also provides a portable fan, which includes a fan body and a liquid reservoir as described above, wherein the liquid reservoir is disposed on the fan body.

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, and "multiple" herein refers to two or more.

[0024] 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.

[0025] This application provides a liquid storage tank for a portable fan. By using an integrated molded housing and transmission pipe, the joint between the housing and the transmission pipe can be completely sealed, which can effectively enhance the sealing performance of the joint between the transmission pipe and the housing. This can effectively prevent the liquid inside the housing from leaking out through the joint between the transmission pipe and the housing when shaking occurs.

[0026] 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.

[0027] Please see Figure 1This application provides a liquid storage tank 100 for a portable fan. The liquid storage tank 100 for the portable fan includes a housing 110 and a transmission pipe 120 integrally formed with the housing 110. The housing 110 has a liquid storage cavity 111. A part of the transmission pipe 120 is located inside the liquid storage cavity 111, and another part of the transmission pipe 120 is located outside the liquid storage cavity 111.

[0028] There are many ways to integrally form the housing 110 and the transmission pipe 120. They can be formed by injection molding, rotational molding, or other integral forming methods such as 3D printing. No specific limitation is made here.

[0029] In this embodiment, the entire transmission pipe 120 is integrally formed with the housing 110. This arrangement ensures the sealing of the joint between the transmission pipe 120 and the housing 110, enhances the connection strength between the transmission pipe 120 and the housing 110, and ensures the sealing of all positions on the transmission pipe 120. In other embodiments, the transmission pipe 120 may also include a middle section and two outer sections, with only the middle section integrally formed with the housing 110, and the two outer sections threadedly connected to the two ends of the middle section along its axial direction.

[0030] Both the housing 110 and the liquid storage chamber 111 can have various shapes, including regular shapes such as cuboids, cylinders, and elliptical cylinders, as well as irregular shapes; no specific limitation is made here. Similarly, the transmission pipe 120 can also have various shapes, including straight lines, curves, wavy lines, broken lines, spiral lines, and other shapes; no specific limitation is made here.

[0031] The number of housings 110, the number of liquid storage chambers 111, and the number of transmission pipes 120 can all be one or more; the housings 110 and liquid storage chambers 111, as well as the housings 110 and transmission pipes 120, can be arranged in a one-to-one or one-to-many manner; when the housings 110 and liquid storage chambers 111 are arranged in a one-to-many manner, the multiple liquid storage chambers 111 can be interconnected, and correspondingly, at least one liquid storage chamber 111 is connected to a transmission pipe 120; the multiple liquid storage chambers 111 can be independent of each other, and correspondingly, each liquid storage chamber 111 is connected to a transmission pipe 120; when the housings 110 and transmission pipes 120 are arranged in a one-to-many manner, the multiple transmission pipes 120 can be located on the same side of the housing 110, or the multiple transmission pipes 120 can be located on different sides of the housing 110, without specific limitations. Figure 1 The diagram shows a case where the housing 110, the liquid storage chamber 111, and the transfer pipe 120 are all configured as a single unit.

[0032] By way of example and not limitation, the transmission conduit 120 can be a rigid conduit, i.e., a hard pipe, which facilitates docking or fitting with other components; the transmission conduit 120 can also be a flexible conduit, such as a corrugated pipe, silicone tube, etc.; obviously, when there are multiple transmission conduits 120, the type and shape of each transmission conduit 120 can be the same or different.

[0033] In this embodiment, the transmission pipe 120 extends vertically in a straight line, thus minimizing the path for the liquid to pass through it and effectively reducing the time required for the liquid to pass through the transmission pipe 120. In other embodiments, the transmission pipe 120 may also be configured as a straight line extending obliquely in the vertical direction.

[0034] In some embodiments, the inner diameter of the transmission pipe 120 can be set slightly smaller than the outer diameter of the outer pipe. This allows the outer pipe to be tightly clamped and fixed by the transmission pipe 120 when inserted into it, thereby enhancing the sealing and connection strength between the transmission pipe 120 and the outer pipe. Furthermore, a limiting portion (not shown) extending circumferentially can be provided on the inner peripheral wall of the transmission pipe 120 near its outlet end. After the outer pipe is inserted from the outlet end of the transmission pipe 120, it abuts against the limiting portion, thus facilitating confirmation that the outer pipe is properly inserted.

[0035] By using the above technical solution, the housing 110 and the transmission pipe 120 are integrally formed. When the housing 110 and the transmission pipe 120 are integrally formed, the joint between the housing 110 and the transmission pipe 120 can be completely sealed, which can effectively enhance the sealing performance of the joint between the transmission pipe 120 and the housing 110. This can effectively prevent the liquid inside the housing 110 from easily leaking out through the joint between the transmission pipe 120 and the housing 110 when shaking occurs.

[0036] Considering that if the portion of the transfer pipe 120 located within the liquid storage chamber 111 could extend to the bottom wall of the liquid storage chamber 111, all the liquid within the liquid storage chamber 111 could be drawn out through the transfer pipe 120, please refer to [reference needed]. Figure 1 In one embodiment of the application, the transmission pipeline 120 includes an inlet section 121 and an outlet section 122 connected in sequence. The inlet section 121 and the outlet section 122 are located inside and outside the storage chamber 111, respectively. Both the inlet section 121 and the outlet section 122 are integrally formed with the housing 110. The side of the inlet section 121 away from the outlet section 122 extends to the bottom wall adjacent to the storage chamber 111, so that the transmission pipeline 120 can extend to the bottom wall of the storage chamber 111.

[0037] It is worth mentioning that when the side of the inlet section 121 away from the outlet section 122 is adjacent to the bottom wall of the storage chamber 111, there is a small gap between the side of the inlet section 121 away from the outlet section 122 and the bottom wall of the storage chamber 111, which allows liquid to flow into the transmission pipe 120.

[0038] In other embodiments, the inlet section 121 and the outlet section 122 can also be indirectly connected. In this case, the housing 110 has a communication port, and the inlet section 121 and the outlet section 122 are connected to the two ends of the communication port in the axial direction. In other embodiments, the side of the inlet section 121 away from the outlet section 122 can also be set at a small distance from the bottom wall of the liquid storage chamber 111.

[0039] Please see Figure 1 In one embodiment of the application, the length of the inlet section 121 is greater than the length of the outlet section 122. This arrangement reduces the internal space occupied by the outlet section 122 when the liquid storage tank 100 of the portable fan is applied to the portable fan 1000 described below, thus facilitating the installation of other components within the portable fan 1000. The multiple of the length of the inlet section 121 to the length of the outlet section 122 is selected from any one of 2, 3, 4, 5, or 6 times, or a range formed by any two of these multiples.

[0040] In other embodiments, the length of the inlet section 121 may be less than the length of the outlet section 122, or the length of the inlet section 121 may be equal to the length of the outlet section 122.

[0041] Please see Figure 1 and Figure 2 In one embodiment of the application, the bottom wall of the liquid storage chamber 111 is provided with a liquid injection port 112 that can be opened or closed. The liquid injection port 112 is located beside the inlet end of the transmission pipe 120. With this configuration, when adding liquid to the liquid storage chamber 111 through the liquid injection port 112, the box body 110 is first inverted with the bottom facing upward, so that the lowest position of the bottom wall of the liquid storage chamber 111 is flipped to the top, and the liquid injection port 112 is located beside this position. Then the liquid injection port 112 is opened, and the corresponding liquid is added to the liquid storage chamber 111 through the liquid injection port 112, so that the liquid storage chamber 111 can be almost full when adding liquid to the liquid storage chamber 111. Obviously, when the housing 110 is inverted, the outlet end of the liquid outlet section 122 of the transmission pipe 120 is in a sealed connection with the atomizing nozzle 400, which will be described below, through the external pipe. Therefore, when liquid is added while the housing 110 is inverted, the liquid will not leak from the outlet end of the liquid outlet section 122.

[0042] In this embodiment, please refer to Figure 1 and Figure 2By setting an injection plug 113 at the injection port 112, the injection port 112 can be opened or closed. In other embodiments, a one-way valve can also be set at the injection port 112, and the opening or closing of the one-way valve can be controlled to open or close the injection port 112.

[0043] Considering that the length of the outlet section 122 is constant, if the storage chamber 111 can be divided into two storage spaces of different depths, with the inlet section 121 located in the shallower storage space, the length of the inlet section 121 can be shortened. This minimizes the path for the liquid to pass through the inlet section 121, effectively reducing the time required for the liquid to pass through the inlet section 121, and consequently, the time required for the liquid to pass through the transmission pipe 120. Therefore, please refer to... Figure 3 In one embodiment of the application, the top wall of the liquid storage cavity 111 is stepped, so that the liquid storage cavity 111 has a first liquid storage cavity 1111 and a second liquid storage cavity 1112 that are connected. The top wall of the first liquid storage cavity 1111 is lower than the top wall of the second liquid storage cavity 1112. The bottom wall of the first liquid storage cavity 1111 and the bottom wall of the second liquid storage cavity 1112 are flush. The liquid inlet section 121 extends directly from the bottom wall of the first liquid storage cavity 1111 to the top wall of the first liquid storage cavity 1111. In this way, the liquid inlet section 121 is located in the liquid storage space with a smaller depth between the first liquid storage space and the second liquid storage space.

[0044] To facilitate the complete extraction of liquid from the storage chamber 111, please refer to [link / reference]. Figure 1 and Figure 2 In one embodiment of the application, the bottom wall of the liquid storage chamber 111 has a first position and a second position, the first position being lower than the second position, and the inlet end of the transmission pipe 120 being adjacent to the first position. Specifically, the first position is the lowest position of the bottom wall of the liquid storage chamber 111, and the second position is the highest position of the bottom wall of the liquid storage chamber 111. This arrangement ensures that the inlet end of the transmission pipe 120 is located at the lowest position of the bottom wall of the liquid storage chamber 111. As the liquid in the liquid storage chamber 111 is gradually drawn out, the liquid in the liquid storage chamber 111 will always flow to the inlet end of the transmission pipe 120 under the action of gravity, thereby facilitating the complete extraction of the liquid in the liquid storage chamber 111.

[0045] In other embodiments, the first position and the second position can also be set to a position between the highest and lowest positions of the bottom wall of the liquid storage cavity 111.

[0046] There are many ways in which the bottom wall of the aforementioned liquid storage chamber 111 forms the first position and the second position; please refer to [the relevant documentation]. Figure 1 and Figure 2In one embodiment of the application, the bottom wall of the liquid storage cavity 111 is arranged in a concave cone shape. This arrangement can form both the first position and the second position, and can also increase the volume of the liquid storage cavity 111.

[0047] In other embodiments, the bottom wall of the liquid storage cavity 111 can be set as an inclined surface that is inclined in the vertical direction, which can also form the first position and the second position.

[0048] Please see Figure 3 and Figure 4 This application also provides a portable fan 1000, which includes a fan body 200 and a liquid storage tank 100 as described above. The liquid storage tank 100 is disposed on the fan body 200. The specific structure of the liquid storage tank 100 of the portable fan is the same 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.

[0049] By way of example and not limitation, the liquid storage tank 100 of the portable fan and the fan body 200 can be integrally formed. The specific method of integral forming is set with reference to the integral forming method in the above embodiments, which will not be repeated here. The liquid storage tank 100 and the fan body 200 of the portable fan can also be fixed by means of bonding, ultrasonic welding or other fixed connection. The liquid storage tank 100 and the fan body 200 of the portable fan can also be fixed by means of detachable connection such as snap-fit, snap-fit ​​connection, threaded connection, magnetic connection or other detachable connection.

[0050] In this embodiment, please refer to Figure 3 and Figure 4 The portable fan 1000 also includes an air pump 300 and an atomizing nozzle 400. Both the air pump 300 and the atomizing nozzle 400 are mounted on the fan body 200. The air inlet of the atomizing nozzle 400 is connected to the air pump 300, and the liquid inlet of the atomizing nozzle 400 is connected to the outlet of the transmission pipe 120 via an external pipe. Utilizing the siphon principle generated by the air pump 300, liquid can be drawn from the liquid storage chamber 111 through the transmission pipe 120 to the atomizing nozzle 400 for atomization. Obviously, in other embodiments, the portable fan 1000 can also include an atomizing plate and an atomizing nozzle. The atomizing plate is installed in the liquid storage chamber 111, and the atomizing nozzle is installed on the fan body 200. The atomizing nozzle is connected to the outlet of the transmission pipe 120 via an external pipe, which can also atomize the liquid in the liquid storage chamber 111.

[0051] It is understood that the fan body 200 can be configured as an integrated handheld structure, which can be both held and used for blowing air; the fan body 200 can also be configured to include a fan part 210 and a handheld part 220, with the handheld part 220 and the fan part 210 connected together. The connection method between the two is set as in the above embodiments of fixed connection or detachable connection, which will not be described in detail here. The following will describe the formation of the liquid storage tank 100 of the portable fan when the fan body 200 includes the fan part 210 and the handheld part 220.

[0052] Please see Figure 1 In one embodiment, the handheld unit 220 is integrally formed with a housing 110, a transmission pipe 120, and a mounting cavity 221 located above the housing 110. The outlet end of the transmission pipe 120 is located inside the mounting cavity 221, and the side of the mounting cavity 221 away from the housing 110 is open. This arrangement allows the liquid storage tank 100 of the portable fan to be integrally formed at the bottom of the handheld unit 220. Liquid can be added directly into the housing 110 of the handheld unit 220 without any additional steps, making the liquid addition operation simple. In other embodiments, the liquid storage tank 100 of the portable fan can also be set as a separate component and then installed on the handheld unit 220.

[0053] Furthermore, the portable fan 1000 also includes a battery 500. The battery 500 and the air pump 300 are installed in the mounting cavity 221 in the front-to-back direction. With this arrangement, since the air pump 300 and the battery 500 are arranged in the mounting cavity 221 in the front-to-back direction, the width of the handheld part 220 in the left-to-right direction can be effectively reduced. This achieves the goal of installing an additional power source for the spraying function in the handheld part 220 while effectively reducing the size of the handheld part 220, making it convenient for the user to hold.

[0054] In addition, the shape of the bottom wall of the mounting cavity 221 is adapted to the shape of the top wall of the liquid storage cavity 111 so that the bottom wall of the mounting cavity 221 is also stepped. The mounting cavity 221 has two chambers 2211 arranged sequentially in the front-back direction. The depth of one chamber 2211 is greater than the depth of the other chamber 2211. The depth refers to the length along the vertical direction. The air pump 300 and the battery 500 are located in the two chambers 2211 respectively. With this arrangement, the air pump 300 or battery 500 can be accommodated in the deeper chamber of the two chambers 2211, so that a larger air pump 300 or battery 500 can be accommodated.

[0055] As an example, and not a limitation, the liquid outlet section 112 of the transmission pipe 120 is located at the bottom of the deeper chamber 2211 of the two chambers 2211. Correspondingly, the outlet end of the liquid outlet section 112 of the transmission pipe 120 may not exceed the bottom wall of the shallower chamber 2211 of the two chambers 2211. Alternatively, the outlet end of the liquid outlet section 112 of the transmission pipe 120 may be flush with the bottom wall of the shallower chamber 2211 of the two chambers 2211. Or, the outlet end of the liquid outlet section 112 of the transmission pipe 120 may slightly exceed the bottom wall of the shallower chamber 2211 of the two chambers 2211. In all these ways, the liquid outlet section 112 will not occupy too much space in the mounting cavity 221, which is conducive to the installation of other components.

[0056] 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.
