Description

Technical Field

[0001] This application relates to the field of fan technology, and more specifically, to a novel liquid storage tank and a portable fan. Background Technology

[0002] In the iterative innovation of fans, a portable fan with atomization function has been designed. The shell of this portable fan has a liquid storage chamber and an air exchange port. The air exchange port connects the liquid storage chamber and the internal space of the shell, and an air exchange structure is installed at the air exchange port.

[0003] The defects of the above-mentioned prior art are: because the vent is connected to the internal space of the shell, and there is a certain assembly gap between the vent and the vent structure, the liquid in the storage chamber will leak into the internal space of the shell. In severe cases, the electronic components in the internal space of the shell will be damaged due to water immersion. Therefore, it is urgent to improve it. Utility Model Content

[0004] Therefore, it is necessary to provide a new type of liquid storage tank to address the above problems, which aims to effectively prevent the liquid in the storage chamber from leaking into the internal space of the shell, so as to ensure that the electronic components in the internal space of the shell will not be damaged by water immersion.

[0005] The embodiments of this application achieve the above objectives through the following technical solutions.

[0006] This application provides a novel liquid storage tank, which includes a shell, a partition, and a venting and liquid-blocking component.

[0007] The outer side of the housing has a vent, the partition is detachably installed inside the housing, and the partition and the housing form a liquid storage cavity. The venting and liquid-blocking device is installed on the partition, and the liquid storage cavity is in airflow communication with the vent through the venting and liquid-blocking device.

[0008] In one embodiment, the venting and liquid-blocking element is installed on the side of the separator facing the liquid storage chamber.

[0009] In one embodiment, the separator has an inner side facing the reservoir and an outer peripheral side surrounding the inner side;

[0010] The separator extends from the outer periphery to the inner side, forming a ventilation channel; the ventilation channel is connected to the ventilation port on the outer periphery side, and the ventilation liquid barrier covers the ventilation channel on the inner side.

[0011] In one embodiment, the air-sealing liquid-blocking element is a one-way valve and / or a waterproof and breathable membrane.

[0012] In one embodiment, the inner side is further provided with an insertion hole, and the air exchange liquid barrier is configured as an umbrella valve. The umbrella valve includes a valve stem and a valve cover. The valve stem cooperates with the insertion hole, and the valve cover covers the side of the air exchange channel located on the inner side.

[0013] In one embodiment, the ventilation channel includes a first segment and a second segment connected at an angle, the side of the first segment away from the second segment being located on the outer periphery and communicating with the ventilation port, and the side of the second segment away from the first segment being located on the inner side and covered by the ventilation liquid barrier.

[0014] In one embodiment, the venting and liquid-blocking element is disposed near the edge of the separator.

[0015] In one embodiment, the outer peripheral side of the separator is sealed to the inner peripheral wall of the housing.

[0016] In one embodiment, the separator further surrounds the housing to form a mounting cavity, the mounting cavity being located on one side of the liquid storage cavity, and the side of the mounting cavity away from the liquid storage cavity being open.

[0017] This application also provides a portable fan, which includes the novel liquid storage tank described above.

[0018] Compared with the prior art, the embodiments of this application have the following advantages: The novel liquid storage tank in this application features a vent on the outer side of the shell, a detachable partition installed inside the shell, the partition and shell forming a liquid storage cavity, a venting and liquid-blocking component installed on the partition, and the liquid storage cavity communicating with the vent through the venting and liquid-blocking component. This arrangement effectively prevents liquid leakage from the liquid storage cavity into the internal space of the shell, ensuring that the electronic components inside the shell are not damaged by water immersion. Furthermore, since the venting and liquid-blocking component is installed on the detachable partition, it is not necessary to insert into the narrow space of the shell to disassemble or install the component; simply removing the partition from the shell is sufficient for disassembly and assembly, making the disassembly and assembly of the venting and liquid-blocking component convenient.

[0034] 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.

[0035] 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.

[0036] This application provides a novel liquid storage tank for use in a portable fan. The liquid storage chamber on the housing is connected to the air vent on the outside of the housing via a non-traditional method through a detachable partition with a ventilator and liquid-blocking component. This achieves pressure balance within the liquid storage chamber, effectively preventing liquid leakage from the storage chamber into the internal space of the housing. This ensures that the electronic components inside the housing are not damaged by water immersion.

[0037] 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.

[0038] Please see Figure 1 and Figure 2 This application provides a novel liquid storage tank 100, which includes a shell 10, a partition 20, and a ventilating and liquid-blocking component 30.

[0039] The housing 10 provides installation space for other components such as the separator 20 and the venting and liquid-blocking component 30, and the outer side of the housing 10 has a vent 10a. The housing 10 can have various shapes, including cuboid, cylindrical, prismatic, and other shapes, without specific limitations. Similarly, the vent 10a can also have various shapes, including regular shapes such as circular, square, rhomboid, elliptical, and oval, as well as other irregular shapes, without specific limitations.

[0040] There are many ways to form the ventilation port 10a. In this embodiment, the inner peripheral wall portion of the housing 10 extends directly to the outer peripheral wall of the housing 10 to form the ventilation port 10a. This ensures that the ventilation port 10a is located on the outer peripheral wall of the housing 10, preventing it from being blocked when the housing 10 is placed, thus avoiding any impact on ventilation. In other embodiments, the inner peripheral wall portion of the housing 10 may extend to the top or bottom end face of the housing 10 to form the ventilation port 10a.

[0041] The separator 20 is detachably installed inside the housing 10, and the separator 20 and the housing 10 surround to form a liquid storage cavity 10b. The ventilator 30 is installed on the separator 20, and the liquid storage cavity 10b is in airflow communication with the vent 10a through the ventilator 30.

[0042] There are many ways to form the shell 10 and the partition 20. In this embodiment, both the shell 10 and the partition 20 are single, complete components integrally formed by injection molding, 3D printing, or other machining methods. This ensures the sealing of the liquid storage cavity 10b formed by the partition 20 and the shell 10. In other embodiments, the shell 10 can also be assembled from multiple components. In this document, "multiple" refers to at least two components. The multiple components can be fixed by detachable connections such as snap-fit, snap-fit, magnetic connection, and tenon joint. The multiple components can also be fixed by fixed connections such as adhesive or welding. No specific limitation is made here.

[0043] Specifically, the partition 20 is configured as a plate-shaped structural member, which ensures that the thickness of the partition 20 is uniform at all locations, thereby minimizing the space occupied by the partition 20 within the housing 10. Alternatively, the partition 20 can also be configured as a stamped part with uneven surfaces.

[0044] There are many ways to detachably install the separator 20 within the housing 10. In this embodiment, the outer peripheral side 20c of the separator 20 is interference-fitted with the inner peripheral wall of the housing 10. This arrangement allows for detachable installation of the separator 20 while ensuring a tight seal between the outer peripheral side 20c of the separator 20 and the inner peripheral wall of the housing 10. Furthermore, in practical applications, the size of the liquid storage chamber 10b can be adjusted by changing the position of the separator 20 in the extending direction of the housing 10. In other embodiments, the separator 20 can also be detachably installed within the housing 10 using other detachable connection methods such as snap-fit ​​connection or magnetic connection as described above.

[0045] The partition 20 can be set to one or more, and "more" in this article refers to at least two. When there are multiple partitions 20, there are correspondingly multiple vents 10a. The multiple partitions 20 and the housing 10 surround and form multiple liquid storage chambers 10b. Each partition 20 is equipped with a venting and liquid-blocking component 30, and each liquid storage chamber 10b is connected to the corresponding vent 10a through the corresponding venting and liquid-blocking component 30. Similarly, the vent 10a and the venting and liquid-blocking component 30 can also be set to one or more, and the partition 20 and the venting and liquid-blocking component 30 can be set in a one-to-one or one-to-many manner, without specific limitations here. Figure 1 The diagram illustrates the case where there is only one separator 20 and one air-sealing liquid-sealing component 30.

[0046] The ventilator-liquid separator 30 has both ventilator and liquid separator functions. Venilator function includes at least one of allowing gas in the liquid storage chamber 10b to flow out of the vent 10a to the outside of the housing 10 and allowing gas outside the housing 10 to flow into the liquid storage chamber 10b through the vent 10a. Liquid separator function includes preventing liquid in the liquid storage chamber 10b from flowing out of the vent 10a.

[0047] As an example, and not a limitation, the liquid storage chamber 10b can be connected to the air exchange port 10a via the air exchange liquid-blocking component 30 to allow only air intake, or the liquid storage chamber 10b can be connected to the air exchange port 10a via the air exchange liquid-blocking component 30 to allow only air exhaust, or the liquid storage chamber 10b can be connected to the air exchange port 10a via the air exchange liquid-blocking component 30 to allow both air intake and air exhaust.

[0048] Through the above technical solution, when assembling the new liquid storage tank 100, the venting and liquid-blocking component 30 is first installed on the partition 20, and then the partition 20 is installed at a predetermined position inside the housing 10 to form a liquid storage cavity 10b. The liquid storage cavity 10b is then connected to the vent 10a on the outside of the housing 10 via the venting and liquid-blocking component 30, thus completing the assembly of the new liquid storage tank 100. When disassembling the new liquid storage tank 100, the partition 20 is first removed from the housing 10, and then the venting and liquid-blocking component 30 is removed from the partition 20, thus completing the disassembly of the new liquid storage tank 100. In summary, in this application, the liquid storage cavity 10b is connected to the vent 10a on the outside of the housing 10 via the venting and liquid-blocking component 30, thereby effectively preventing liquid leakage from the liquid storage cavity 10b into the internal space of the housing 10, ensuring that the electronic components inside the housing 10 are not damaged by water immersion. Furthermore, since the ventilator-liquid separator 30 is installed on the detachable separator 20, when disassembling and assembling the ventilator-liquid separator 30, it is not necessary to insert into the narrow space of the housing 10 to disassemble and assemble the ventilator-liquid separator 30. The ventilator-liquid separator 30 can be disassembled and assembled simply by removing the separator 20 from the housing 10, making the disassembly and assembly of the ventilator-liquid separator 30 convenient.

[0049] In other embodiments, a ventilation hole can be provided on the separator 20 to connect the liquid storage chamber 10b and the internal space of the housing 10, and the liquid storage chamber 10b can be connected to the ventilation hole for airflow through the ventilation and liquid separation member 30.

[0050] Further, please refer to Figure 1 and Figure 2The liquid storage chamber 10b has a through-hole forming an installation port 10c facing the cavity wall of the separator 20. The novel liquid storage tank 100 also includes a cover 40, which can seal or open the installation port 10c. With this configuration, the liquid storage chamber 10b can be filled or cleaned by first opening the installation port 10c through the cover 40. The installation method of the cover 40 is the same as the detachable installation method in the above embodiment, and will not be described in detail here.

[0051] Furthermore, please refer to Figures 1 to 3 The separator 20 also surrounds the housing 10 to form a mounting cavity 10d. The mounting cavity 10d is located on one side of the liquid storage cavity 10b, and the side of the mounting cavity 10d away from the liquid storage cavity 10b is open, so that the mounting cavity 10d can provide mounting positions for other components of the portable fan 1000.

[0052] In this embodiment, the housing 10 is a cylindrical shape with open ends. Its lower end is sealed by a cover 40, and its upper end is open. Therefore, when the separator 20 is installed inside the housing 10, an installation cavity 10d and a liquid storage cavity 10b can be formed that are spaced apart vertically and independently of each other. In other embodiments, the housing 10 may also be a shell with an open upper end and a sealed lower end.

[0053] Please see Figure 1 and Figure 2 There are many possible installation positions of the aforementioned ventilator-liquid separator 30 on the separator 20. In one embodiment of this application, the ventilator-liquid separator 30 is installed on the side of the separator 20 facing the liquid storage cavity 10b. Specifically, the separator 20 has an inner side 20a facing the liquid storage cavity 10b, an outer side 20b opposite to the inner side 20a, and an outer peripheral side 20c connecting the inner side 20a and the outer side 20b. The outer peripheral side 20c is arranged around the inner side 20a and the outer side 20b. The ventilator-liquid separator 30 is installed on the inner side 20a. This arrangement makes the installation of the ventilator-liquid separator 30 convenient, and also ensures that the ventilator-liquid separator 30 is located inside the liquid storage cavity 10b and does not occupy the space of the internal mounting cavity 10d of the housing 10.

[0054] In other embodiments, the outer peripheral side 20c of the separator 20 may be recessed to form an installation space, and the air-sealing liquid-sealing component 30 may be installed in the installation space. Alternatively, the air-sealing liquid-sealing component 30 may be embedded in the outer peripheral side 20c of the separator 20.

[0055] There are many ways in which the liquid storage chamber 10b is connected to the air exchange port 10a via the air exchange liquid barrier 30. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 4In one embodiment of this application, the separator 20 extends from the outer peripheral side 20c through the inner side 20a to form a ventilation channel 20d. The ventilation channel 20d is located on one side of the outer peripheral side 20c and communicates with the ventilation port 10a. The ventilation and liquid-blocking component 30 covers the ventilation channel 20d located on the inner side 20a. With this arrangement, the airflow between the liquid storage chamber 10b and the ventilation port 10a can be achieved through the ventilation channel 20d and the ventilation and liquid-blocking component 30, so as to maintain the air pressure balance in the liquid storage chamber 10b.

[0056] In other embodiments, the ventilator 30 may be embedded in the outer peripheral side 20c and cover the side of the ventilator channel 20d located on the outer peripheral side 20c; or the separator 20 may have a receiving notch formed at the connection between its inner side 20a and the outer peripheral side 20c, and the receiving notch and the inner peripheral wall of the housing 10 may form an airflow channel connecting the ventilator 10a and the liquid storage chamber 10b, and the ventilator 30 may cover the side of the airflow channel that is connected to the liquid storage chamber 10b.

[0057] It is worth mentioning that both the ventilation channel 20d and the ventilation liquid-blocking component 30 can be configured as one or more, and the ventilation channel 20d and the ventilation liquid-blocking component 30 can be configured in a one-to-one, one-to-many, or many-to-one manner. For example, when there is one ventilation channel 20d, there can be one ventilation liquid-blocking component 30, covering one side of the ventilation channel 20d along its axial direction; or, when there is one ventilation channel 20d, there can be two ventilation liquid-blocking components 30, with the two components covering both sides of the ventilation channel 20d along its axial direction; or, when there are two ventilation channels 20d, there can be one ventilation liquid-blocking component 30, covering the same side of both ventilation channels 20d along their axial direction, with the two ventilation channels 20d corresponding to the two ventilation ports 10a. Figure 1 This situation is illustrated in the diagram, and will not be listed in detail here.

[0058] There are many types of the aforementioned ventilation channel 20d; please refer to [link / reference]. Figure 1 and Figure 2 In one embodiment of this application, the ventilation channel 20d includes a first segment 21d and a second segment 22d connected at an angle. The side of the first segment 21d away from the second segment 22d is located on the outer peripheral side 20c and communicates with the ventilation port 10a. The side of the second segment 22d away from the first segment 21d is located on the inner side 20a and is covered by the ventilation liquid barrier 30. With this arrangement, the gas flowing into it can be guided through the connection between the first segment 21d and the second segment 22d, which facilitates the intake and exhaust of the liquid storage chamber 10b.

[0059] Specifically, the first segment 21d and the second segment 22d are perpendicular to each other, which facilitates the processing and forming of the first segment 21d and the second segment 22d. In addition, the first segment 21d and the second segment 22d can also be connected at an acute angle or at an obtuse angle.

[0060] In other embodiments, the ventilation channel 20d may also be arranged in a straight line. Accordingly, the ventilation channel 20d is inclined in the vertical direction, with the lower end of the ventilation channel 20d located on the inner side 20a and the upper end of the ventilation channel 20d located on the outer peripheral side 20c.

[0061] There are many types of ventilator-liquid barrier components 30. These components can include at least one type of check valve and waterproof breathable membrane. Check valves come in various types, such as umbrella valves, duckbill valves, cantilever valves, bridge valves, wheel valves, two-end fixed-support valves, spring valves, and other one-way ventilated and waterproof structures. A check valve is an automatic valve that allows gas to flow in one direction while preventing reverse flow. Its core principle is to utilize the fluid's own pressure in conjunction with the valve's internal structure to achieve a one-way flow function. A waterproof breathable membrane is a selectively permeable film. Its core principle is to utilize the material's microporous structure and surface tension to achieve a "waterproof and breathable" function.

[0062] When the venting and liquid-blocking component 30 is configured as an umbrella valve, please refer to... Figure 1 , Figure 2 , Figure 4 as well as Figure 5 In one embodiment of this application, the inner side 20a is further provided with an insertion hole 21e. The venting and liquid-blocking component 30 includes a valve stem 31 and a valve cover 32. The valve stem 31 cooperates with the insertion hole 21e, and the valve cover 32 covers one side of the ventilation channel 20d located on the inner side 20a. This arrangement facilitates the installation of the venting and liquid-blocking component 30. In other embodiments, the venting and liquid-blocking component 30 can also be installed on the separator 20 by means of a fixed connection or a detachable connection as described in the above embodiments.

[0063] Specifically, the insertion hole 21e is set as a blind hole, which can effectively prevent the liquid in the liquid storage chamber 10b from leaking into the space inside the housing 10 through the insertion hole 21e.

[0064] When the air pressure outside the housing 10 is greater than the air pressure inside the liquid storage chamber 10b, the valve cover 32 is subjected to the air pressure from the outside of the housing 10, causing the valve cover 32 to undergo elastic deformation, opening the ventilation channel 20d. The gas outside the housing 10 flows into the liquid storage chamber 10b after passing through the ventilation port 10a and the ventilation channel 20d in sequence, until the air pressure outside the housing 10 and the air pressure inside the liquid storage chamber 10b are restored to equilibrium. Under the action of its own rebound force, the valve cover 32 returns to the state of covering the ventilation channel 20d.

[0065] In other embodiments, the valve cover 32 may cover the ventilation channel 20d on the outer peripheral side 20c. When the air pressure in the liquid storage chamber 10b is greater than the air pressure outside the housing 10, the valve cover 32 is subjected to the air pressure from the liquid storage chamber 10b, causing the valve cover 32 to undergo elastic deformation, opening the ventilation channel 20d. The gas in the liquid storage chamber 10b flows into the outside of the housing 10 after passing through the ventilation channel 20d and the ventilation port 10a in sequence, until the air pressure in the liquid storage chamber 10b and the air pressure outside the housing 10 are restored to equilibrium. Under the action of its own rebound force, the valve cover 32 returns to the state of covering the ventilation channel 20d. Of course, two ventilation and liquid isolation components 30 and two ventilation channels 20d may also be provided, with the valve cover 32 of one ventilation and liquid isolation component 30 covering the ventilation channel 20d on the inner side 20a, and the valve cover 32 of the other ventilation and liquid isolation component 30 covering the ventilation channel 20d on the outer peripheral side 20c.

[0066] Further, please refer to Figure 4 and Figure 5 The valve stem 31 has a limiting ring 311 extending circumferentially around its outer periphery. The inner circumferential wall of the insertion hole 21e has a limiting groove 211e that mates with the limiting ring 311. This ensures that the valve stem 31 remains stable and does not loosen when the valve cover 32 is subjected to air pressure. Furthermore, the thickness of the limiting ring 311 gradually decreases in the direction from the valve stem 31 to the limiting ring 311. This results in inclined limiting walls 311a being formed on both the side of the limiting ring 311 facing the valve cover 32 and the side of the limiting ring 311 facing away from the valve cover 32. The limiting groove 211e is adapted to the limiting ring 311, and the limiting wall 311a can guide the valve stem 31 during disassembly and assembly, making the disassembly and assembly of the valve stem 31 convenient.

[0067] To shorten the connection path between the liquid storage chamber 10b and the vent 10a, please refer to... Figure 1 In one embodiment of this application, the ventilator 30 is disposed near the edge of the separator 20, and correspondingly, the ventilator channel 20d is disposed near the edge of the separator 20, which can effectively shorten the connection path between the liquid storage chamber 10b and the ventilator 10a.

[0068] In other embodiments, the air-sealing liquid-sealing element 30 may also be disposed in the middle of the separator 20.

[0069] To prevent liquid in the storage chamber 10b from leaking between the outer peripheral side 20c of the separator 20 and the inner peripheral wall of the housing 10, please refer to... Figure 2 and Figure 4In one embodiment of this application, the outer peripheral side 20c of the separator 20 is sealed to the inner peripheral wall of the housing 10. Specifically, the outer peripheral side 20c of the separator 20 is integrally formed with a sealing ring 201 extending circumferentially therefrom, and the inner peripheral wall of the housing 10 is provided with a sealing groove 10e extending circumferentially therefrom, and the sealing ring 201 engages with the sealing groove 10e. The sealing ring 201 can be configured as one ring or multiple rings. Figure 2 When the middle sealing ring 201 is set to two rings, and the connection position between the air exchange channel 20d and the air exchange port 10a is between the two sealing rings 201, the air exchange channel 20d and the air exchange port 10a can be sealed and connected.

[0070] Please see Figure 1 and Figure 6 This application also provides a portable fan 1000, which includes the novel liquid storage tank 100 and a fan body 200 as described above. The novel liquid storage tank 100 is disposed on the fan body 200. The specific structure of the novel liquid storage tank 100 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.

[0071] In this embodiment, please refer to Figure 1 and Figure 6 The fan body 200 includes a fan section 210 and a handheld section. The housing 10 of the liquid storage tank 100 is formed as the outer shell of the handheld section, which facilitates the formation of the outer shell of the handheld section. Correspondingly, the air vent 10a is located on the outer periphery of the handheld section.

[0072] In other embodiments, the fan body 200 can also be configured as an integral component, and the housing 10 of the novel liquid storage tank 100 can be used as the outer shell of the fan body 200, or the housing 10 of the novel liquid storage tank 100 can be used as part of the outer shell of the fan body 200. It can be fixed by means of bonding, welding or other fixed connection, or by means of detachable connection such as plug-in, snap-fit ​​connection, magnetic connection, threaded connection.

[0073] By way of example, and not limitation, the vent 10a can be located at a lower outer periphery of the handle, a higher outer periphery of the handle, or a central outer periphery of the handle. Obviously, users typically hold the handle in the central part; therefore, when the vent 10a is located at a lower or higher outer periphery of the handle, it effectively prevents the air pressure balance within the liquid reservoir 10b from being affected by the user obstructing the vent 10a while holding the handle.

[0074] 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.
