Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and more specifically to evaporative air coolers. Background Technology

[0002] A portable air purifier is a type of air conditioner. Due to its small size and ease of movement, it is widely popular. An air purifier consists of a casing, a blower assembly, a evaporative cooling pad, a water tank, and a water supply assembly. The blower assembly, evaporative cooling pad, and water supply assembly are all housed within the casing. The water tank stores water. The water supply assembly supplies water to the evaporative cooling pad, keeping it continuously moist. The evaporative cooling pad utilizes the principle of lowering air temperature through evaporation. The blower assembly blows air onto the evaporative cooling pad, accelerating airflow and thus speeding up the temperature reduction.

[0003] One type of existing air cooler has a pull-out water tank. Pull-out water tanks require an additional connecting mechanism between the tank and the outer casing, and this connection is fixed and non-removable. The pull-out water tank limits the air cooler's storage capacity when not in use. Another type of existing air cooler uses clips to achieve a detachable connection between the water tank and the outer casing. However, these clips are laborious and difficult to install and remove, making water tank storage inconvenient.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To address or improve to some extent the technical problem of inconvenient water tank storage in existing air coolers, this invention provides an air cooler. The air cooler includes: a body with a partition at its bottom; a water tank with a water storage cavity inside; and a locking assembly disposed on the body. The locking assembly is configured to lock the water tank in a working position connected to the partition and to unlock the water tank from the partition, allowing the water tank to be moved to a storage position upside down on the body.

[0006] Those skilled in the art will understand that the air cooler of the present invention includes a body, a partition, a water tank, and a locking assembly. The partition, water tank, and locking assembly are all mounted on the body. The body is the main part of the air cooler that blows cool air. The water tank has an internal cavity that stores water, providing water for cooling the air in the body. The locking assembly locks or unlocks the water tank and the partition. When the locking assembly locks the water tank and the partition, the body and the water tank cannot be disassembled, and the water tank is in the working position, ensuring that the body can continuously and stably receive water from the water tank, thereby ensuring the high efficiency of the air cooler. When the locking assembly unlocks the water tank and the partition, the body and the water tank can be disassembled, facilitating the removal of the water tank from the body and its inverted placement on the body, reducing the space occupied by the air cooler when stored. The locking assembly facilitates the installation and removal of the water tank and the body, thus facilitating the storage of the water tank and making the air cooler more convenient to use.

[0007] In the preferred embodiment of the above-mentioned air cooler, the partition is provided with a through hole, and the locking component includes: a locking member, which is slidably connected to the body and can pass through the through hole; and a locking groove, which is arranged on the water tank and opposite to the through hole, wherein the locking member is inserted into or disengaged from the locking groove to lock or unlock the water tank.

[0008] With the above setup, when the locking element slides through the through hole and inserts into the locking groove on the machine body, its position is restricted by the locking groove, thus limiting the position between the water tank and the partition and fixing the water tank in the working position. When the locking element slides out of the locking groove on the machine body, there is no restriction between the locking groove and the locking element, making the water tank and the partition separable. This allows the water tank to be removed from the partition and placed upside down on the machine body. By inserting and releasing the locking element into the locking groove, the conversion between the non-separable and separable states of the machine body and the water tank is achieved. This is convenient to use, less strenuous than manually prying the buckles, and prevents hand injuries, providing a good user experience.

[0009] In the preferred embodiment of the above-mentioned air cooler, the locking assembly further includes a button connected to the locking member; the body includes an inner core and a housing covering the inner core, wherein the housing has a mounting hole that allows the button to be inserted, and the button is constrained in the mounting hole.

[0010] With the above settings, the mounting hole limits the button to slide within the mounting hole, preventing the button from falling out of its predetermined position. This ensures that the button accurately disengages from or inserts into the locking groove within the predetermined position of the mounting hole, improving the accuracy of the locking component's insertion into the locking groove and increasing the working efficiency of the locking assembly.

[0011] In the preferred embodiment of the above-mentioned air cooler, the locking assembly further includes: a support plate connected to the housing; and an elastic element located between the support plate and the button, the elastic element providing elastic force to the button so that the button drives the locking element to insert into the locking groove.

[0012] With the above setup, the support plate provides support for the pop-out button of the elastic element. The elastic element stores elastic potential energy between the support plate and the button, enabling it to provide elastic force to the button. This allows the button to automatically drive the locking element into the locking slot, eliminating the need for manual button movement and insertion of the locking element, making it convenient to use.

[0013] In the preferred embodiment of the above-mentioned air cooler, the elastic element is a helical spring.

[0014] With the above configuration, the helical spring itself can be compressed and extended, providing elastic force to the button between the support plate and the button. In addition, the helical spring can store elastic potential energy through its own helical structure. Compared with an elastic block, its elasticity is not easily affected by environmental factors such as temperature and humidity, and the elastic potential energy can be maintained for a longer period of time, ensuring that the locking element is accurately inserted into the locking groove for a long time and extending the service life of the locking assembly.

[0015] In the preferred embodiment of the above-mentioned air cooler, the support plate is provided with a limiting ring surrounding the elastic element, so that the elastic element is constrained in the limiting ring.

[0016] With the above settings, the limiting ring restricts the deformation space of the elastic element, allowing the elastic element to extend and retract within the predetermined space of the limiting ring, accurately popping out the button and improving the accuracy of the button driving the locking element to insert into the locking groove.

[0017] In the preferred embodiment of the above-mentioned cooling fan, when the water tank is in the working position, the through hole and the locking groove are flush in the vertical direction, so that the locking member can be horizontally inserted into the locking groove.

[0018] With the above settings, the through hole and the locking groove are flush in the vertical direction, ensuring that the locking component is inserted into the locking groove more accurately and improving the locking efficiency between the water tank and the machine body.

[0019] In the preferred embodiment of the above-mentioned air cooler, the housing is provided with a handle groove spaced apart from the mounting hole.

[0020] With the above-mentioned design, the handle groove provides a gripping space for the user to move the air cooler, making it easier to move the machine and disassemble the machine and water tank, thus improving the user experience.

[0021] In the preferred embodiment of the above-mentioned air cooler, the button is provided with a limiting protrusion, the outer shell is provided with a guide groove for the limiting protrusion to slide, the side of the guide groove has a limiting end, the limiting end is away from the inner core, so as to restrict the limiting protrusion from sliding to the position farthest from the inner core.

[0022] With the above settings, the limiting end restricts the limiting protrusion to the farthest position from the inner core, preventing the button from slipping out of the mounting hole due to excessive sliding distance. This restricts the button to slide within the mounting hole, thereby ensuring the operational stability of the locking component and improving the efficiency of disassembly and assembly between the water tank and the machine body.

[0023] In the preferred embodiment of the above-mentioned air cooler, the through holes include a first through hole and a second through hole spaced apart from each other; the locking member includes a first locking member inserted into the first through hole and a second locking member inserted into the second through hole; and the locking groove includes a first locking groove corresponding to the first locking member and a second locking groove corresponding to the second locking member.

[0024] With the above configuration, the first and second locking components are inserted into the first and second locking slots respectively, which increases the stability of the locking components' positioning in the locking slots and makes the fixation between the water tank and the machine body more stable. In other words, the double-insertion structure further restricts the degree of freedom of the locking components along the direction perpendicular to the insertion, avoiding situations where the locking components are not aligned with the locking slots due to excessive gaps between a single locking component and a single locking slot, thus improving the efficiency of the locking assembly in locking the water tank and the machine body.

[0037] To address or improve to some extent the technical problem of inconvenient water tank storage in existing air coolers, this invention provides an air cooler 100. The air cooler 100 includes: a body 1 with a partition 13 at its bottom; a water tank 2 with a water storage cavity inside; and a locking assembly 3 disposed on the body 1. The locking assembly 3 is configured to lock the water tank 2 in a working position connected to the partition 13, and to unlock the water tank 2 from the partition 13, allowing the water tank 2 to be moved to a storage position where it is inverted on the body 1.

[0038] Figure 1 This is a schematic diagram of the cooling fan structure of the present invention. See also... Figure 1 In one or more embodiments, the air cooler 100 of the present invention includes a body 1, a water tank 2 and a locking component 3.

[0039] Figure 2 This is a cross-sectional view of the water tank of the cooling fan of the present invention. See also... Figure 2 In one or more embodiments, the body 1 includes an inner core 11 and an outer shell 12 covering the inner core 11. The outer shell 12 has a hollow cavity inside, providing a suitable mounting area for the inner core 11. The inner core 11 is fixedly disposed inside the outer shell 12. The inner core 11 includes a blower assembly (not shown) and a evaporative cooling pad (not shown). The evaporative cooling pad utilizes the principle of reducing air temperature through moisture evaporation to lower the temperature of the air passing through it. The blower assembly blows air onto the evaporative cooling pad, accelerating airflow and thus accelerating the reduction of air temperature.

[0040] Figure 3 yes Figure 2 A partial cross-sectional view of the locking component in section A. See also Figure 3 In one or more embodiments, the housing 12 is provided with a mounting hole 121 that allows the button 32 of the locking assembly 3 to be inserted. The size of the mounting hole 121 is specifically determined according to the size of the button 32, such that the button 32 can move within the mounting hole 121. Specifically, the diameter of the mounting hole 121 extends horizontally from the inside of the housing 12 toward the outside.

[0041] See also Figure 1 and Figure 3 In one or more embodiments, the housing 12 is provided with a handle recess 122 spaced apart from the mounting hole 121. Specifically, the handle recess 122 is provided on the side wall of the housing 12 near the top. The size of the handle recess 122 is set according to the size of most human hands, so that most people's hands can enter the handle recess 122. The handle recess 122 provides a gripping space for the hand to move the machine body 1, which facilitates the hand to move the machine body 1, thereby facilitating the disassembly and reassembly between the machine body 1 and the water tank 2 and improving the user experience. The number of handle recesses 122 can be set to one, two or other suitable numbers according to actual needs to facilitate the movement of the machine body 1.

[0042] See also Figure 2 and Figure 3In one or more embodiments, a partition 13 is provided at the bottom of the body 1. Specifically, the partition 13 is fixedly connected to the bottom of the outer casing 12. The fixing method between the partition 13 and the outer casing 12 can be, but is not limited to, bolt connection, riveting, or welding. The partition 13 is located between the water tank 2 and the body 1. The partition 13 can separate the water tank 2 from the body 1, preventing water in the water tank 2 from entering the body 1, thereby preventing short circuits in the circuit of the body 1 and preventing damage to the fan, thus extending the service life of the cooling fan 100. The partition 13 is provided with a through hole 131. The through hole 131 of the partition 13 allows the locking member 31 of the locking assembly 3 to pass through. The size of the through hole 131 is specifically determined according to the size of the locking member 31, so that the locking member 31 can move in the through hole 131. The shape of the through hole 131 can be, but is not limited to, circular or square.

[0043] See also Figure 3 In one or more embodiments, the partition 13 and the water tank 2 are detachably connected. Specifically, a connector 132 is fixedly connected to the outer edge of the partition 13. The connector 132 is arranged in a ring around the outer edge of the partition 13. The inner side of the connector 132 abuts against the outer side of the opening edge of the water tank 2. The connector 132 is elastic. When the water tank 2 is installed on the partition 13, the connector 132 undergoes elastic deformation, allowing the opening edge of the water tank 2 to be inserted into the annular space formed by the connector 132. The elastically deformed connector 132 abuts against the outer side of the opening of the water tank 2, increasing the pressure between the connector 132 and the water tank 2, thereby increasing the friction between the partition 13 and the water tank 2, making the fixation between the water tank 2 and the partition 13 more secure. When the water tank 2 is fixedly installed on the partition 13, the water tank 2 is fixed to the bottom of the body 1, and the water tank 2 is in the working position.

[0044] Figure 4 This is a schematic diagram of the structure of the water tank of the refrigerated fan of the present invention, inverted onto the machine body. See also... Figure 4 In one or more embodiments, when the water tank 2 is separated from the partition 13, the water tank 2 is inverted on top of the body 1 and is in the storage position.

[0045] See also Figure 1 and Figure 4 In one or more embodiments, the water tank 2 has an internal cavity for storing water. The cavity of the water tank 2 is capable of accommodating the machine body 1. The volume of the cavity can be, but is not limited to, the entire volume of the machine body 1 or a portion thereof. An opening is provided on one side of the water tank 2. The opening communicates with the cavity. The size of the opening is specifically determined based on the cross-sectional area of ​​the top of the machine body 1, so that the top of the machine body 1 can enter the cavity through the opening of the water tank 2, allowing the water tank 2 to be inverted and placed on top of the machine body 1. The shape of the water tank 2 can be, but is not limited to, a cuboid, a cylinder, or a polygonal prism.

[0046] See also Figure 3 In one or more embodiments, a locking groove 21 is provided on the inner side of the water tank 2. The locking member 31 of the locking assembly 3 is inserted into or disengaged from the locking groove 21 to lock or unlock the water tank 2 by the body 1. A gap is left between the locking member 31 and the locking groove 21 to allow the locking member 31 to move smoothly in the locking groove 21. The locking groove 21 of the water tank 2 is opposite to the through hole 131 of the partition 13. When the water tank 2 is in the working position, the through hole 131 and the locking groove 21 are flush in the vertical direction, so that the locking member 31 can be inserted horizontally into the locking groove 21. The flushness of the through hole 131 and the locking groove 21 in the vertical direction ensures that the locking member 31 is inserted into the locking groove 21 more accurately, thereby improving the locking efficiency between the water tank 2 and the body 1.

[0047] It should be noted that the evaporative air cooler 100 also includes a water supply assembly (not shown in the figure). The water supply assembly is used to supply water to the evaporative cooling pad to keep it continuously moist. The water supply assembly includes a water pipe (not shown in the figure). The water pipe is fixedly connected to the inside of the water tank 2. One end of the water pipe communicates with the receiving cavity. The other end of the water pipe is connected to the evaporative cooling pad of the unit 1. See also... Figure 1 In one or more embodiments, when the cooling fan 100 is working normally, the water tank 2 is installed on the partition 13, the water tank 2 is in the working position, the containment cavity stores water, and the water pipe guides the water to the water curtain, so that the body 1 can blow out cold air by utilizing the principle of water evaporation to cool down.

[0048] See also Figure 4 In one or more embodiments, when the cooling fan 100 is stored, the water tank 2 is removed from the partition 13, the water in the receiving cavity is poured out, and the water tank 2 is inverted on the top of the body 1. The water tank 2 is in the storage position, which reduces the space occupied and facilitates storage in transportation and idle situations.

[0049] Figure 5 yes Figure 3 A schematic diagram of the locking state of the locking component in the image. See also... Figure 5 In one or more embodiments, the locking component 3 is configured to lock the water tank 2 in a working position connected to the partition 13. Figure 6 yes Figure 3 A structural diagram illustrating the unlocked state of the locking component. See also... Figure 6 In one or more embodiments, the locking component 3 can also unlock the water tank 2 from the partition 13, allowing the water tank 2 to be moved to a storage position where it is upside down on the body 1. Specifically, the locking component 3 is located at the bottom of the body 1.

[0050] See also Figure 5 and Figure 6In one or more embodiments, the locking assembly 3 includes a locking member 31. The locking member 31 is slidably connected to the body 1 and passes through the through hole 131 of the partition 13. Specifically, the locking member 31 slides inside the housing 12. The locking member 31 is disposed on the side of the button 32 of the locking assembly 3 near the partition 13, facilitating the passage of the locking member 31 through the through hole 131 of the partition 13, making the structure simpler and easier to manufacture. The fixed end of the locking member 31 is fixedly connected to the button 32. The fixing method between the locking member 31 and the button 32 may be, but is not limited to, welding, gluing, or the button 32 and the locking member 31 being integrally formed. The free end of the locking member 31 passes through the through hole 131 of the partition 13 and extends in a direction away from the inner core 11. When the locking member 31 is inserted into the locking groove 21, the partition 13 is fixed to the water tank 2. When the locking member 31 disengages from the locking groove 21, the water tank 2 is removed from the partition 13, allowing the water tank 2 to be inverted on top of the body 1.

[0051] See also Figure 6 In one or more embodiments, the locking assembly 3 further includes a button 32 connected to the locking member 31. Specifically, the button 32 is constrained in the mounting hole 121. A gap is left between the button 32 and the mounting hole 121 to allow the button 32 to slide within the mounting hole 121. When the button 32 is pressed toward the interior of the housing 12, the button 32 causes the locking member 31 to disengage from the locking groove 21. By pressing the button 32, the locking member 31 can be separated from the locking groove 21, making it easier to disassemble the water tank 2 from the partition 13. An anti-slip layer (not shown in the figure) is provided on the side of the button 32 away from the inner core 11. The anti-slip layer may be, but is not limited to, a rubber sheet fixed to the surface of the button 32, multiple grooves on the surface of the button 32, or multiple protrusions on the surface of the button 32.

[0052] See also Figure 5 In one or more embodiments, the locking assembly 3 further includes a support plate 33 and an elastic element 34. The support plate 33 is connected to the housing 12. Specifically, the support plate 33 is fixedly connected to the inner side of the housing 12. The support plate 33 is located at the bottom of the body 1. The support plate 33 and the button 32 are arranged opposite each other on a horizontal plane. The elastic element 34 is located between the support plate 33 and the button 32. The elastic element 34 provides elastic force to the button 32, so that the button 32 drives the locking element 31 to insert into the locking groove 21. The support plate 33 provides support for the elastic element 34 to eject the button 32. The extension and retraction direction of the elastic element 34 is parallel to the direction of the mounting hole 121, so that the elastic element 34 ejects the button 32 in a direction parallel to the diameter of the mounting hole 121. The elastic element 34 stores elastic potential energy between the support plate 33 and the button 32, so that the elastic element 34 can provide elastic force to the button 32, thereby automatically driving the locking element 31 to insert into the locking groove 21 without the need for manual movement of the button 32, making it convenient to use. The elastic element 34 can be an elastic block or a coil spring.

[0053] See also Figure 5 In one or more embodiments, the elastic element 34 is a helical spring. One end of the helical spring abuts against the button 32. The other end of the helical spring abuts against the support plate 33. The central axis of the helical spring is coaxially arranged with the diameter of the mounting hole 121. The helical spring always stores elastic potential energy between the button 32 and the support plate 33, so that the button 32 is always in the popped-out state, thereby placing the button 32 at the end of the mounting hole 121 away from the inner core 11, making it easier for the hand to contact the button 32 and improving the user experience. In addition, the elastic potential energy of the helical spring can cause the button 32 to drive the locking element 31 to abut tightly against the locking groove 21, preventing the water tank 2 from separating from the partition plate 13 due to external forces such as vibration, and making the fixation between the water tank 2 and the body 1 more secure.

[0054] See also Figure 5 In one or more embodiments, a support plate 33 is fixedly connected to a support rod 36. The support rod 36 is located on the side of the support plate 33 closest to the button 32. A helical spring is sleeved on the support rod 36. The support rod 36 is arranged along the extension and retraction direction of the helical spring, which can limit the extension and retraction direction of the helical spring on the support rod 36, ensuring that the helical spring pops out of the button 32 in a predetermined direction, thereby ensuring that the locking member 31 can be accurately inserted into the locking groove 21, improving the locking accuracy of the locking assembly 3.

[0055] See also Figure 5 In one or more embodiments, the support plate 33 is provided with a limiting ring 35 surrounding the elastic member 34, so that the elastic member 34 is constrained in the limiting ring 35. Specifically, the limiting ring 35 is fixedly connected to the side of the support plate 33 near the elastic member 34. The specific shape of the limiting ring 35 may be, but is not limited to, a circular ring or an elliptical ring. The elastic member 34 is located in the inner space surrounding the limiting ring 35. The central axis of the limiting ring 35 is set along the extension and retraction direction of the elastic member 34. It can be understood that the inner side of the limiting ring 35 restricts the extension and retraction direction of the elastic member 34 to the central axis, improving the accuracy of the extension and retraction of the elastic member 34, thereby improving the accuracy of the button 32 driving the locking member 31 to insert into the locking groove 21, and improving the working efficiency of the locking assembly 3.

[0056] See also Figure 3In one or more embodiments, the button 32 is provided with a limiting protrusion 321, and the outer shell 12 is provided with a guide groove 123 for the limiting protrusion 321 to slide. The side of the guide groove 123 has a limiting end, which is away from the inner core 11, to limit the limiting protrusion 321 from sliding to the position furthest from the inner core 11. Specifically, the limiting protrusion 321 is fixedly connected to the button 32. The fixing method between the limiting protrusion 321 and the button 32 can be, but is not limited to, welding, bonding, or the limiting protrusion 321 and the button 32 being integrally formed. The guide groove 123 is arranged along the diameter direction of the mounting hole 121. The limiting end is specifically the inner side of the guide groove 123 away from the inner core 11. A gap is left between the guide groove 123 and the limiting protrusion 321, allowing the limiting protrusion 321 to slide smoothly within the guide groove 123. When the limiting protrusion 321 moves toward the limiting end in a direction away from the inner core 11, the limiting protrusion 321 stops moving, and the button 32 connected to the limiting protrusion 321 stops moving, preventing the elastic element 34 from popping the button 32 out of the mounting hole 121, and restricting the button 32 to slide in the mounting hole 121, thereby ensuring the operational stability of the locking component 3 and improving the disassembly and assembly efficiency between the water tank 2 and the body 1.

[0057] In one or more embodiments, the through hole 131 includes a first through hole (not shown) and a second through hole (not shown) spaced apart from each other. The locking member 31 includes a first locking member (not shown) inserted into the first through hole and a second locking member (not shown) inserted into the second through hole. The locking groove 21 includes a first locking groove (not shown) corresponding to the first locking member and a second locking groove (not shown) corresponding to the second locking member. Specifically, the first through hole and the second through hole are arranged side-by-side on a horizontal plane. The first locking groove and the second locking groove are also arranged side-by-side on a horizontal plane. The first locking member and the second locking member are also arranged side-by-side on a horizontal plane. When the water tank 2 is in the working position, the first through hole and the second through hole are flush with the first locking groove and the second locking groove in the vertical direction, allowing the first locking member and the second locking member to be horizontally inserted into the first locking groove and the second locking groove, respectively. This increases the stability of the locking member 31 in the locking groove 21, making the fixation between the water tank 2 and the body 1 more stable. In other words, by using a double-insertion structure, the degree of freedom of the locking member 31 along the direction perpendicular to the insertion direction is further restricted, avoiding the situation where the locking member 31 is not aligned with the locking groove 21 due to the excessive gap between the single locking member 31 and the single locking groove 21, thereby improving the efficiency of the locking assembly 3 in locking the water tank 2 and the body 1.

[0058] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
