Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a refrigerator. Background Technology

[0002] With the upgrading of consumption, in addition to low-temperature preservation, refrigerators have an increasingly urgent need for moisturizing fruits and vegetables, making humidification devices a core component of mid-to-high-end refrigerators. Ultrasonic atomization humidification is widely used due to its high efficiency and uniform water mist. Its water storage box needs to be detachable for water addition and cleaning to prevent bacterial growth. Therefore, the fixing mechanism between the water storage box and the shell has become a key technology.

[0003] In existing technologies, the implementation of refrigerator humidification devices mostly involves setting up a water storage structure and a spray component in the door or cabinet. The water storage structure is installed in a preset installation position by means of threaded connection, magnetic fixation, etc., to ensure the stability of the water storage structure under scenarios such as refrigerator door opening and closing and transportation bumps.

[0004] However, the threaded connection method locks the water storage box into the housing cavity with screws, which is structurally stable but requires tools to disassemble and is cumbersome to operate; the magnetic fixing method uses the magnetic attraction force to position the water storage box, which is easy to disassemble but the attraction force is easily affected by vibration and may loosen and shift after long-term use.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0006] This utility model aims to at least partially solve one of the technical problems in the related art.

[0007] Therefore, according to a first aspect of the embodiments of this disclosure, a refrigerator is provided, comprising: The enclosure defines multiple cavities; A door, which is rotatably mounted on the housing to close or open the receiving cavity; A humidifying device is used to humidify the receiving cavity; the humidifying device includes: The housing has a mounting cavity. A water storage box is disposed within the mounting cavity, the water storage box having a communicating water storage chamber and a spray nozzle; the spray nozzle is configured to spray water mist toward the receiving cavity; A locking mechanism is used to fix the water storage box within the mounting cavity; the locking mechanism includes: A stop portion is provided on the inner surface of the housing; A telescopic latching part is provided on the side wall of the water storage box. The telescopic latching part can move telescopically relative to the water storage box. The telescopic latching part cooperates with the stop part to lock or unlock the water storage box from the housing. A telescopic mechanism is provided to drive the telescopic latching part to extend or retract relative to the water storage box. The telescopic mechanism drives the telescopic locking part to move toward the water storage box, so that the telescopic locking part disengages from the stop part, and the water storage box is unlocked from the housing.

[0008] In the above technical solution, the water storage box can be quickly fixed and disassembled without damage in the installation cavity through the cooperation of the stop, the telescopic locking part and the telescopic mechanism. No tools are needed. When the water storage box is pulled out, the telescopic mechanism can drive the telescopic locking part to disengage from the stop, which solves the problem of cumbersome disassembly of traditional threaded connections. At the same time, the movable contact structure between the telescopic locking part and the stop ensures that the water storage box is stable and does not loosen in scenarios such as opening and closing the refrigerator door and bumping during transportation. It overcomes the defects of magnetic fixation that are easy to loosen, takes into account the installation stability and operation convenience, and can also avoid wear and tear on the water storage box or shell during disassembly.

[0009] In some embodiments of this application, a first groove is provided on the lower surface of the housing, and the opening direction of the first groove is the same as the opening direction of the mounting cavity; When the water storage box is located inside the mounting cavity, the telescopic mechanism is partially located inside the first groove.

[0010] In the above technical solution, a first groove is provided on the lower surface of the housing, which is aligned with the opening direction of the mounting cavity. When the water storage box is located in the mounting cavity, the telescopic mechanism is located in the first groove, providing a precise installation and positioning space for the telescopic mechanism. This ensures that the telescopic mechanism does not deviate or jam when it moves, and improves the reliability of the locking mechanism.

[0011] In some embodiments of this application, the telescopic mechanism further includes: The first pull rod is located below the water storage box. When the water storage box is located inside the mounting cavity, the first pull rod is located outside the housing. The second pull rod is disposed at the end of the first pull rod, and the second pull rod passes through the first groove and abuts against the side of the telescopic locking part away from the spray nozzle.

[0012] In the above technical solution, a telescopic mechanism is constructed by the cooperation of the first pull rod and the second pull rod. The first pull rod is located outside the housing, which is convenient for users to operate directly. The second pull rod passes through the first groove and abuts against the telescopic locking part to achieve precise force transmission. Users only need to pull the first pull rod to drive the telescopic locking part to move through the second pull rod, which reduces the difficulty of operation and improves the user experience when adding water and cleaning the water storage box.

[0013] In some embodiments of this application, the telescopic latching portion includes: The snap-fit ​​block has a sliding cavity on the side wall of the water storage box, and the snap-fit ​​block is slidably installed in the sliding cavity, and the snap-fit ​​block is in active contact with the stop part; A first elastic element is located inside the sliding cavity. The first end of the first elastic element abuts against the cavity wall of the sliding cavity, and the second end of the first elastic element abuts against the end of the locking block away from the stop portion.

[0014] In the above technical solution, the combination of the snap-fit ​​block slidably installed in the sliding cavity and the first elastic member ensures that the first elastic member always applies an elastic force toward the stop to the snap-fit ​​block, thereby ensuring that the snap-fit ​​block can tightly abut against the stop after the water storage box is installed in place, enhancing the fixation stability and effectively resisting the risk of loosening caused by refrigerator vibration. The structure in which the snap-fit ​​block is slidably installed in the sliding cavity limits the movement trajectory of the snap-fit ​​block, preventing it from being misaligned or falling off, and improving the structural reliability of the locking mechanism.

[0015] In some embodiments of this application, a limiting groove is provided on the cavity wall of the sliding cavity; The snap-fit ​​block is provided with a limit block, which is slidably connected to the limit groove.

[0016] In the above technical solution, a limiting groove is provided in the cavity wall of the sliding cavity, and a limiting block is provided on the locking block, which is slidably connected to the limiting groove. Through the cooperation between the limiting block and the limiting groove, the sliding stroke of the locking block is precisely limited, preventing the locking block from detaching from the sliding cavity due to excessive sliding or from being damaged due to excessive compression with the stop. At the same time, it prevents excessive deformation of the first elastic element, protecting the performance of the elastic element. This ensures that the locking block and the stop always maintain the optimal contact position, guarantees the consistency of the locking effect, and improves the stability and durability of the locking mechanism.

[0017] In some embodiments of this application, the side of the snap-fit ​​block closest to the spray nozzle is defined as the first side surface, the side opposite to the first side surface is defined as the second side surface, and the connecting surface connecting the first side surface and the second side surface is defined as the third side surface. Along the direction from the first side surface to the second side surface, the third side surface extends away from the stop portion; the second pull rod abuts against the surface of the third side surface. The first side of the snap-fit ​​block abuts against the stop portion.

[0018] In the above technical solution, the surface of the snap-fit ​​block near the stop is designed with an inclination. With the help of the inclined guiding characteristics of the snap-fit ​​block, the pulling force of the second pull rod can be efficiently decomposed into the force that drives the snap-fit ​​block to retract into the sliding cavity, making the operation easier and the response more sensitive.

[0019] In some embodiments of this application, the telescopic mechanism includes: The first link, the first end of the first link being rotatably connected to the telescopic locking part; The second connecting rod has its first end rotatably connected to the second end of the first connecting rod, and its middle part rotatably connected to the bottom wall of the water storage box. The third link, one end of which is rotatably connected to the second end of the second link; A pull rod, which is rotatably connected to the other end of the third link.

[0020] In the above technical solution, a telescopic mechanism is constructed by combining a first link, a second link, a third link, and a pull rod. The multi-link transmission structure can accurately convert the linear motion of the pull rod into the telescopic motion of the telescopic locking part. It has high transmission efficiency and smooth operation, avoiding the problem of jamming in a single transmission structure. It improves the versatility and structural flexibility of the locking mechanism and ensures reliable locking and unlocking functions in a limited space.

[0021] In some embodiments of this application, a fixing plate is provided on the bottom wall of the water storage box; A fixed shaft is provided on the fixed plate, a second elastic element is sleeved on the fixed shaft, and the fixed shaft passes through the pull rod; One end of the second elastic member abuts against the pull rod, and the other end of the second elastic member abuts against the fixed plate.

[0022] In the above technical solution, a fixed shaft with a second elastic element is installed on a fixed plate on the bottom wall of the water storage box. The fixed shaft passes through the pull rod, and the two ends of the second elastic element abut against the pull rod and the fixed plate, respectively. The second elastic element always applies an elastic restoring force to the pull rod, so that the pull rod maintains its initial position when not subjected to external force, ensuring that the telescopic locking part and the stop part are stably engaged. When the pull rod is pulled to unlock, releasing the pull rod will automatically reset under the action of the second elastic element, causing the telescopic locking part to re-engage with the stop part, improving the ease of operation. In addition, the fixed shaft guides the pull rod, preventing it from deviating during movement, and the second elastic element can also buffer the impact force during the movement of the pull rod, reducing the wear and tear of parts and protecting the structure of the mechanism.

[0023] In some embodiments of this application, a mounting groove is provided on the bottom wall of the water storage box, the telescopic snap-fit ​​part is disposed in the mounting groove, and a first through hole is provided on the groove wall of the mounting groove, the position of the first through hole being adapted to the position of the pull rod; A second through hole is provided on the bottom wall of the housing, and the position of the second through hole is adapted to that of the first through hole.

[0024] In the above technical solution, a mounting groove is provided on the bottom wall of the water storage box for installing the telescopic snap-fit ​​part, so that the telescopic snap-fit ​​part is embedded in the water storage box, without occupying external space, avoiding interference with the shell or other components, and protecting the telescopic snap-fit ​​part from external collision damage; the first through hole on the groove wall is matched with the second through hole on the bottom wall of the shell, providing a precise installation and movement channel for the pull rod, ensuring that the user can pull the pull rod when using it, and improving the sealing and reliability of the overall structure.

[0025] A second aspect of the embodiments of this application also discloses a refrigerator, comprising: The enclosure defines multiple cavities; A door, which is rotatably mounted on the housing to close or open the receiving cavity; A humidifying device is used to humidify the receiving cavity; the humidifying device includes: The housing has a mounting cavity and is mounted on the door body; A water storage box is disposed within the mounting cavity, the water storage box forming a water storage chamber and a spray nozzle; the spray nozzle is configured to spray water mist toward the receiving cavity. A locking mechanism is used to fix the water storage box within the mounting cavity; the locking mechanism includes: A stop is provided on the side wall of the water storage box; A telescopic latching part is provided on the inner surface of the housing. The telescopic latching part cooperates with the stop part to lock or unlock the water storage box from the housing. A telescopic mechanism is provided to drive the telescopic latching part to telescopically extend or retract relative to the housing. The telescopic mechanism drives the telescopic locking part to move toward the housing, so that the telescopic locking part disengages from the stop part, and the water storage box is unlocked from the housing.

[0026] In the above technical solution, the stop is set on the side wall of the water storage box, and the telescopic latching part is set on the inner surface of the shell. The reverse-layout locking mechanism also realizes the reliable fixation and convenient disassembly of the water storage box and the shell, adapting to different humidification device installation scenarios. The telescopic mechanism drives the telescopic latching part to move closer to the shell to unlock. The operation logic is clear. The user can complete the unlocking action when pulling out the water storage box without additional tools. This ensures that when the shell is installed on the door, the water storage box can still maintain the advantages of stable installation and convenient disassembly. At the same time, the design of spraying water mist from the spray nozzle towards the receiving cavity ensures uniform humidification and meets the humidification needs of fruits and vegetables in the refrigerator, taking into account both structural adaptability and functional practicality.

[0031] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0035] As consumers' demands for food preservation quality continue to rise, refrigerator compartment environmental control technology is facing new challenges. Traditional refrigerators, which rely on low temperatures to delay spoilage, are no longer sufficient to meet consumers' demands for refined preservation indicators such as the moisture content of fruits and vegetables and the firmness of leafy greens. When the humidity inside the refrigerator compartment drops below 70%, leafy green vegetables can lose up to 15% of their moisture within 24 hours, and berries like strawberries experience a three-fold increase in skin wrinkling. This not only accelerates the loss of nutrients but also affects the taste and commercial value of the food. Especially in scenarios where frequent opening and closing of the refrigerator door causes drastic humidity fluctuations, traditional humidity control technologies often suffer from slow response times and slow humidity recovery, making it difficult to maintain a stable humidity environment.

[0036] In related technologies, increasing the humidity of the storage environment improves the preservation effect of food. Ultrasonic atomization humidification technology has advantages such as rapid humidification and low energy consumption and low cost, and is therefore applied to refrigerators due to its unique advantages.

[0037] In existing technologies, ultrasonic atomizing devices are mostly installed inside the door or cabinet. These devices are mounted in a pre-set position using methods such as threaded connections or magnetic fixation to ensure the stability of the water storage structure during refrigerator door opening and closing, and during transport bumps. However, while threaded connections secure the water storage box to the housing cavity with screws, providing a stable structure, disassembly requires tools and is cumbersome. Magnetic fixation uses magnetic attraction to position the water storage box, offering convenient disassembly, but the attraction force is easily affected by vibration, potentially leading to loosening and displacement after prolonged use.

[0038] To address the aforementioned technical problems, this application proposes a refrigerator, as detailed below with reference to the appendix. Figures 1-13 The refrigerator provided in this application will be described in conjunction with specific embodiments.

[0039] This application provides a refrigerator, as shown in the embodiments below. Figure 1 Figure 13The refrigerator includes a cabinet 100 having a receiving cavity 101, a door 200 connected to the cabinet 100 for opening and closing the receiving cavity 101, and a refrigeration unit for supplying cold air to the receiving cavity 101. The cabinet 100 includes an inner liner defining the receiving cavity 101, an outer shell connected to the outside of the inner liner to form the appearance of the refrigerator, and a heat insulation layer disposed between the inner liner and the outer shell to insulate the receiving cavity 101. The refrigeration system may include a compressor, a condenser, a throttling device, and an evaporator connected in a cycle.

[0040] During refrigeration system operation, the compressor compresses refrigerant vapor, generating high-temperature, high-pressure refrigerant vapor, and delivers it to the condenser. The condenser liquefies the high-temperature, high-pressure refrigerant vapor, generating high-temperature, low-pressure refrigerant liquid, which is then delivered to the throttling device. The throttling device reduces the pressure of the refrigerant liquid, transforming it from a high-pressure, low-temperature liquid into a low-pressure, low-temperature liquid, which is then delivered to the evaporator. The evaporator receives the low-pressure, low-temperature refrigerant liquid and boils it under isobaric conditions, absorbing heat and vaporizing to form refrigerant vapor, thereby lowering the temperature inside the refrigerated room.

[0041] In this embodiment, the cabinet 100 may define a plurality of receiving cavities 101. The front end of each receiving cavity 101 has a retrieval opening for placing or removing items, allowing the user to place food into or remove food from the receiving cavity 101 through this opening. A rotatable door 200 is provided on the cabinet 100 to open or close the retrieval opening of the receiving cavity 101. For example, the door 200 is rotatably connected to the cabinet 100 by hinge assemblies located at the upper and lower parts of the refrigerator.

[0042] In some embodiments of this application, the plurality of receiving cavities 101 may include a refrigerator compartment and a freezer compartment. The refrigerator compartment and the freezer compartment are distributed along the width direction of the refrigerator. The refrigerator compartment extends along the height direction of the cabinet 100. The freezer compartment extends along the height direction of the cabinet 100.

[0043] In some embodiments of this application, reference is made to Figure 1 The refrigerator body 100 can be equipped with four doors 200. Two of the four doors 200 are refrigerator doors, and the other two are freezer doors. The refrigerator doors are used to open or close the refrigerator compartment, and the freezer doors are used to open or close the freezer compartment. When the refrigerator door and the freezer door are closed simultaneously, the front wall of the refrigerator door and the front wall of the freezer door together form the front wall of the refrigerator.

[0044] In some embodiments of this application, a door seal is provided on the side wall of the door 200 near the housing 100. The door seal surrounds the access opening. When the door 200 is closed, the door seal adheres to the front face of the housing 100 to effectively seal the connection between the door 200 and the housing 100, thereby ensuring that the door 200 seals the access opening and preventing cold air from escaping.

[0045] In some embodiments, refer to Figure 1 , Figure 2 and Figure 8 The refrigerator may include a humidifier 300. The humidifier 300 is used to humidify the receiving cavity 101. The humidifier 300 can be installed on the cabinet 100 or the door 200. Specifically, the humidifier 300 is installed on the door 200 and is used to humidify the refrigerator compartment.

[0046] In some embodiments of this application, reference is made to Figure 2 , Figure 6 , Figure 8 and Figure 13 The humidifier 300 includes a housing 310, within which a mounting cavity 311 is constructed. The mounting cavity 311 may be located at the front of the housing 310. An installation opening may be formed on the front side of the mounting cavity 311. A shelf may be provided on the side of the door 200 facing the receiving cavity 101, and the housing 310 may be placed on the shelf. The shape of the mounting cavity 311 is adapted to the shape of the water storage box 320, ensuring that the water storage box 320 can be accurately inserted.

[0047] In some embodiments, see Figure 1 , reference Figure 2 , Figure 6 , Figure 8 and Figure 13 The direction from its bottom wall to its top wall is the height direction of the housing 310. The housing 310 may have a front side and a rear side arranged opposite to each other. The side of the housing 310 facing the user can be the front side of the main body, that is, the opening of the receiving cavity 101 is the front side of the housing 310, and the direction from its front side to its rear side is the thickness direction of the housing 310. The housing 310 may have a left side and a right side arranged opposite to each other, and the direction from its left side to its right side is the length direction of the housing 310.

[0048] In some embodiments of this application, reference is made to Figure 2 and Figure 8 The humidifier 300 also includes a water storage box 320 for storing water. The water storage box 320 is disposed within the mounting cavity 311 and is removably mounted within the mounting cavity 311 via a mounting opening, facilitating its removal from the mounting cavity 311. When it is necessary to remove the water storage box 320 from the mounting cavity 311 for refilling, it can be simply pulled out, which is convenient and quick. The water storage box 320 forms a water storage chamber 321 and a spray nozzle 322; the spray nozzle 322 is configured to spray water mist towards the receiving cavity for humidifying and preserving the stone within the receiving cavity 101. The water storage box 320 may be at least partially made of a transparent material, allowing the user to easily observe the remaining water level.

[0049] In some embodiments of this application, reference is made to Figures 2-13 The humidifier 300 may also include a locking mechanism 330, which is used to fix the water storage box 320 to the housing 310 when the water storage box 320 is pushed into the installation cavity 311 from the installation port, so as to prevent the refrigerator door 200 from rotating and the vibration generated by the operation of the equipment, and to prevent the water storage box 320 from shifting, loosening or leaking.

[0050] In some embodiments of this application, reference is made to Figures 3-10 The locking mechanism 330 includes a stop portion 331, a telescopic latching portion 332, and a telescopic mechanism 333. The stop portion 331 can be a protruding structure integrally formed or fixed to the inner surface of the housing 310 by bolts, adhesives, or other means. For example, it is provided on both inner walls of the mounting cavity 311, with a symmetrical layout to ensure uniform fixing force.

[0051] A telescopic latching part 332 is disposed on the side wall of the water storage box 320. The telescopic latching part 332 can telescopically move relative to the water storage box 320, and the telescopic latching part 332 is in active contact with the stop part 331. For example, telescopic latching parts 332 are respectively provided on both side walls of the water storage box 320, corresponding one-to-one with the positions of the stop parts 331. The telescopic latching parts 332 can telescopically move relative to the water storage box 320, thereby forming active contact or disengagement with the stop parts 331, so that the water storage box 320 is locked or unlocked from the housing 310.

[0052] The telescopic mechanism 333 drives the telescopic latching part 332 to move. When the water storage box 320 needs to be pulled out from the mounting cavity 311, the telescopic mechanism 333 drives the telescopic latching part 332 to move towards the water storage box 320, causing the telescopic latching part 332 to disengage from the stop part 331, and the water storage box 320 to unlock from the housing 310. Exemplarily, the telescopic mechanism 333 is drively connected to the telescopic latching part 332 to drive the telescopic latching part 332 to move. When it is necessary to remove the water storage box 320 from the mounting cavity 311, the telescopic mechanism 333 is operated to drive the telescopic locking part 332 to retract and move towards the water storage box 320, so that the telescopic locking part 332 separates from the stop part 331. At this time, the water storage box 320 can be easily pulled out for adding water or cleaning. When the water storage box 320 is inserted into the mounting cavity 311, the telescopic locking part 332 resets and contacts and engages with the stop part 331, thus fixing the water storage box 320.

[0053] During installation, the water storage box 320 is aligned with the mounting cavity 311 of the housing 310 and inserted. After the water storage box 320 is fully inserted, the telescopic locking part 332 extends and abuts against the stop part 331 on the housing 310, using the contact force between the two to restrict the direction of the water storage box 320 being pulled out, thus achieving stable fixation. During disassembly, by operating the telescopic mechanism 333, the telescopic locking part 332 is driven to retract, releasing the locking relationship with the stop part 331. At this time, the water storage box 320 can be pulled out from the mounting cavity 311 without obstruction. This embodiment allows for the assembly and disassembly of the water storage box 320 without the need for any tools, while ensuring stability. Through the cooperation of the stop part 331, the telescopic locking part 332, and the telescopic mechanism 333, the water storage box 320 can be quickly fixed and disassembled without damage within the mounting cavity 311. Without the need for tools, when the water storage box 320 is pulled out, the telescopic mechanism 333 can drive the telescopic locking part 332 to disengage from the stop part 331, solving the problem of cumbersome disassembly of traditional threaded connections. At the same time, the movable contact structure between the telescopic locking part 332 and the stop part 331 ensures that the water storage box 320 remains stable and does not loosen under conditions such as refrigerator door opening and closing and transportation bumps, overcoming the defects of easy loosening of magnetic fixation. It takes into account both installation stability and ease of operation, and can also avoid wear and tear on the water storage box 320 or the shell 310 during disassembly.

[0054] In some embodiments of this application, reference is made to Figure 6 The lower surface of the housing 310 is provided with a first groove 312, and the opening direction of the first groove 312 is the same as the opening direction of the mounting cavity 311; when the water storage box 320 is located in the mounting cavity 311, the telescopic mechanism 333 is partially located in the first groove 312.

[0055] It is understood that there are two first grooves 312, and each first groove 312 is a groove structure extending along the thickness direction of the shell 310, with its opening direction being the same as the opening direction of the mounting cavity 311, i.e., both facing the insertion / removal direction of the water storage box 320. When the water storage box 320 is completely located within the mounting cavity 311, part of the structure of the telescopic mechanism 333 is embedded and located within the first groove 312. The groove width and groove depth of the first groove 312 are adapted to the shape of the telescopic mechanism 333, forming a limiting guide for the telescopic mechanism 333.

[0056] By providing a first groove 312 on the lower surface of the housing 310 that is aligned with the opening direction of the mounting cavity 311, a dedicated installation space is provided for the telescopic mechanism 333, avoiding collision damage caused by the exposed telescopic mechanism 333 or interference with other components, thus improving the overall compactness of the humidification device 300. The first groove 312 precisely limits the movement trajectory of the telescopic mechanism 333, ensuring that the telescopic mechanism 333 does not deviate or jam when driving the telescopic locking part 332, further improving the operational reliability of the locking mechanism 330 and extending its service life.

[0057] In some embodiments of this application, reference is made to Figure 3 and Figure 4 The telescopic mechanism 333 also includes a first pull rod 3331 and a second pull rod 3332. The first pull rod 3331 is located below the water storage box 320 and extends along the length of the housing 310, with its length designed to fit the size of the water storage box 320. When the water storage box 320 is located inside the mounting cavity 311, the first pull rod 3331 is located outside the housing 310. It can be understood that when the water storage box 320 is completely inside the mounting cavity 311, the entire first pull rod 3331 is outside the housing 310, forming a handheld end that is easy for the user to operate. The handheld end may be provided with anti-slip textures or protrusions to improve grip comfort. The second pull rod 3332 is located at the end of the first pull rod 3331 and passes through the first groove 312, abutting against the side of the telescopic locking part 332 away from the spray nozzle 322. For example, two second pull rods 3332 are provided, each vertically disposed at the end of the first pull rod 3331. The two are integrally formed or fixedly connected by threads. The second pull rod 3332 extends along the height direction of the housing 310. The end of the second pull rod 3332 away from the first pull rod 3331 passes through the first groove 312 on the lower surface of the housing 310, extends to the side wall of the water storage box 320, and abuts against the side of the telescopic locking part 332 away from the spray nozzle 322, realizing the direct transmission of force.

[0058] When the water storage box 320 needs to be disassembled, the user holds the outer handheld end of the first pull rod 3331 and pulls it away from the housing 310. The first pull rod 3331 drives the second pull rod 3332 to move synchronously. The second pull rod 3332 applies a pushing force towards the inside of the water storage box 320 to the telescopic locking part 332, driving the telescopic locking part 332 to retract and separate from the stop part 331, at which point the water storage box 320 can be pulled out. After installation, the first pull rod 3331 is released, and the telescopic locking part 332 extends under the action of the reset force, pushing the second pull rod 3332 and the first pull rod 3331 to reset. The telescopic mechanism 333 is constructed by the cooperation of the first pull rod 3331 and the second pull rod 3332. The first pull rod 3331 is located outside the housing 310, accurately transmitting the user's pulling force to the telescopic locking part 332. The operation path is clear, labor-saving and efficient, further reducing the user's operating difficulty. It is convenient for users to operate directly; the second pull rod 3332 passes through the first groove 312 and abuts against the telescopic locking part 332 to achieve precise force transmission. Users only need to pull the first pull rod 3331 to drive the telescopic locking part 332 to move through the second pull rod 3332, reducing the difficulty of operation and improving the user experience when adding water and cleaning the water storage box 320.

[0059] A sliding block is provided on the side of the second pull rod near the water storage box, and a sliding groove is provided on the outer wall of the sliding cavity 328 of the water storage box, with the sliding block interactively connected in the sliding groove.

[0060] In some embodiments of this application, reference is made to Figure 5 and Figure 7 The telescopic locking part 332 includes a locking block 3312 and a first elastic member 3333. A sliding cavity 328 is provided on the side wall of the water storage box 320. The locking block 3312 is slidably installed in the sliding cavity 328, and the locking block 3312 is in movable contact with the stop part 331. Exemplarily, sliding cavities 328 are provided on both side walls of the water storage box 320 at positions corresponding to the stop part 331. The sliding cavity 328 is an inwardly recessed cavity structure. The locking block 3312 is slidably installed in the sliding cavity 328. The shape of the locking block 3312 is adapted to the sliding cavity 328, allowing it to reciprocate linearly along the sliding cavity 328. The end of the locking block 3312 away from the sliding cavity 328 is used to movably contact the stop part 331. The first elastic element 3333 is located inside the sliding cavity 328. The first end of the first elastic element 3333 abuts against the cavity wall of the sliding cavity 328, and the second end of the first elastic element 3333 abuts against the end of the locking block 3312 away from the stop portion 331. The first elastic element 3333 can be an elastic element connecting the ends of the two hooks 331 away from the spray nozzle 322. Specifically, it includes a structure with elasticity such as a helical spring or an elastic band. For example, a metal spring can be used to provide restoring force, mainly to automatically reset the locking block after the hooks 331 rotate and enter the sliding cavity 328. In its natural state, the first elastic element 3333 is in a slightly compressed state, applying an elastic thrust towards the stop portion 331 to the locking block 3312, so that the locking block 3312 always tends to extend out of the sliding cavity 328. For example, a fixing post is provided on the side of each of the two hooks 331 facing the housing 310310, and the two ends of the helical spring are respectively hung on the corresponding fixing post.

[0061] When installing the water storage box 320, the locking block 3312 contacts and is squeezed against the inner wall of the mounting cavity 311 of the housing 310 during insertion, overcoming the elastic force of the first elastic member 3333 and retracting into the sliding cavity 328. When the water storage box 320 is fully inserted and the locking block 3312 moves to the position of the stop part 331, the locking block 3312 automatically extends under the elastic thrust of the first elastic member 3333 and abuts against the stop part 331 to lock in place, thus quickly fixing the water storage box 320. When disassembling, the second pull rod 3332 pushes the locking block 3312 to retract, the first elastic member 3333 is further compressed, and after the water storage box 320 is pulled out, the locking block 3312 resets under the action of the first elastic member 3333.

[0062] The combination of the snap-fit ​​block 3312, which is slidably installed in the sliding cavity 328, and the first elastic member 3333 ensures that the first elastic member 3333 always applies an elastic force toward the stop part 331 to the snap-fit ​​block 3312. This ensures that after the water storage box 320 is installed in place, the snap-fit ​​block 3312 can tightly abut against the stop part 331, thereby enhancing the fixation stability and effectively resisting the risk of loosening caused by refrigerator vibration. The structure of the snap-fit ​​block 3312 slidably installed in the sliding cavity 328 limits the movement trajectory of the snap-fit ​​block 3312, preventing it from being misaligned or falling off, and improving the structural reliability of the locking mechanism 330.

[0063] In some embodiments of this application, reference is made to Figure 5 and Figure 7 A limiting groove 3281 is provided on the cavity wall of the sliding cavity 328; a limiting block 3313 is provided on the snap-fit ​​block 3312, and the limiting block 3313 is slidably connected within the limiting groove 3281. The limiting groove 3281 is an elongated groove extending along the length of the sliding cavity 328 and is provided on the upper cavity wall of the sliding cavity 328. The upper surface of the snap-fit ​​block 3312 is provided with the limiting block 3313 corresponding to the position of the limiting groove 3281. The limiting block 3313 has an outwardly protruding structure, and its size is adapted to the limiting groove 3281. The limiting block 3313 is slidably connected within the limiting groove 3281, and the two form a sliding fit.

[0064] The maximum sliding stroke of the locking block 3312 is precisely limited by the cooperation between the limiting block 3313 and the limiting groove 3281: when the locking block 3312 extends under the action of the first elastic member 3333, the limiting block 3313 abuts against the outer end wall of the limiting groove 3281 to prevent the locking block 3312 from coming out of the sliding cavity 328; when the locking block 3312 retracts, the limiting block 3313 abuts against the inner end wall of the limiting groove 3281 to prevent the locking block 3312 from retracting excessively and causing the first elastic member 3333 to be crushed.

[0065] A limiting groove 3281 is provided in the cavity wall of the sliding cavity 328, and a limiting block 3313 is provided on the locking block 3312, which is slidably connected to the limiting groove 3281. Through the cooperation between the limiting block 3313 and the limiting groove 3281, the sliding stroke of the locking block 3312 is precisely limited, preventing the locking block 3312 from detaching from the sliding cavity 328 due to excessive sliding or from being damaged by excessive compression with the stop part 331. At the same time, it prevents the first elastic member 3333 from being excessively deformed, protecting the performance of the elastic member. This ensures that the locking block 3312 and the stop part 331 always maintain the optimal contact position, ensuring the consistency of the locking effect and improving the stability and durability of the locking mechanism 330.

[0066] In some embodiments of this application, reference is made to Figure 4 and Figure 7The side of the latching block 3312 closest to the spray nozzle 322 is defined as the first side, the side opposite the first side is defined as the second side, and the connecting surface between the first side and the second side is defined as the third side. The third side extends away from the stop portion 331 along the direction from the first side to the second side; the second pull rod 3332 abuts against the surface of the third side. The first side of the latching block 3312 abuts against the stop portion 331.

[0067] In other words, the surface of the locking block 3312 near the stop 331 is designed with an inclination. From the end away from the spray nozzle 322 to the end near the spray nozzle 322, this surface gradually extends towards the stop 331, forming an inclination guide surface. When the water storage box 320 is installed in place, the side of the locking block 3312 near the spray nozzle 322 forms a surface contact with the stop 331, ensuring locking stability.

[0068] When installing the water storage box 320, insert the water storage box 320 into the installation cavity 311. The inclined guide surface of the locking block 3312 first contacts the stop part 331 of the housing 310. As the insertion depth increases, the stop part 331 exerts pressure along the guide surface on the inclined guide surface. This pressure is decomposed into a component force that drives the locking block 3312 to retract into the sliding cavity 328, causing the locking block 3312 to retract automatically without manual operation by the user. After the water storage box 320 is fully inserted, the locking block 3312 extends under the action of the first elastic member 3333, and its side near the spray nozzle 322 abuts tightly against the stop part 331, achieving fixation. Utilizing the mechanical guiding principle, the locking block 3312 automatically retracts and resets during the insertion of the water storage box 320, achieving the convenient effect of immediate fixation upon insertion. At the same time, the surface contact abutment enhances the fixation stability and prevents loosening. Meanwhile, the surface of the latching block 3312 near the stop 331 is designed with an inclination. With the guide characteristics of the inclined surface of the latching block 3312, the pulling force of the second pull rod 3332 can be efficiently decomposed into the force that drives the latching block 3312 to retract into the sliding cavity 328, making the operation easier and the response more sensitive.

[0069] In some embodiments of this application, reference is made to Figure 10 The telescopic mechanism 333 can also be configured with a first connecting rod 3334, a second connecting rod 3335, a third connecting rod 3336, and a pull rod 3337. Specifically, the first end of the first connecting rod 3334 is rotatably connected to the telescopic locking part 332; the first end of the second connecting rod 3335 is rotatably connected to the second end of the first connecting rod 3334, and the middle part of the second connecting rod 3335 is rotatably connected to the bottom wall of the water storage box 320; one end of the third connecting rod 3336 is rotatably connected to the second end of the second connecting rod 3335; and the pull rod 3337 is rotatably connected to the other end of the third connecting rod 3336.

[0070] For example, refer to Figure 10 The first end of the first link 3334 is rotatably connected to the actuating end (the part that contacts the stop part 331) of the telescopic locking part 332, and can rotate flexibly around the connection point. The first end of the second link 3335 is rotatably connected to the second end of the first link 3334 via a pivot, and the middle part of the second link 3335 is rotatably connected to the bottom wall of the water storage box 320 via a fixed shaft 3291, so that the second link 3335 forms a lever structure. One end of the third link 3336 is rotatably connected to the second end of the second link 3335 via a pivot, realizing the transmission of force. One end of the pull rod 3337 is rotatably connected to the other end of the third link 3336 via a pivot, and the other end of the pull rod 3337 extends to the outside of the water storage box 320, forming an operating end.

[0071] When the water storage box 320 needs to be disassembled, the user pulls the operating end of the lever 3337. The lever 3337 drives the third link 3336 to move. The third link 3336 drives the second link 3335 to rotate around the fixed shaft 3291 in the middle part. The second link 3335 then pulls the first link 3334. The first link 3334 drives the actuator end of the telescopic locking part 332 to retract, releasing the engagement with the stop part 331. After installation, the lever 3337 is released, and the telescopic locking part 332 extends under the action of the reset force. The multi-link mechanism drives the lever 3337 to reset, realizing the locking and fixing. The multi-link structure allows for flexible adjustment of the link length and connection angle according to the internal space of the water storage box 320, adapting to humidifiers 300 of different sizes. At the same time, it provides smooth transmission and high force transmission efficiency, avoiding the problem of jamming in a single structure. The multi-link transmission structure can accurately convert the linear motion of the pull rod 3337 into the telescopic locking part 332, resulting in high transmission efficiency and smooth operation. It avoids the problem of jamming in a single transmission structure, improves the versatility and structural flexibility of the locking mechanism 330, and ensures reliable locking and unlocking functions within a limited space.

[0072] Furthermore, a sliding cavity 328 is provided on the lower surface of the water storage box 320, and the actuating end of the telescopic locking part 332 (the part for contacting the stop part 331) may also include a locking block 3312. The surface of the locking block 3312 near the stop part 331 is designed with an inclination, gradually extending from the end away from the spray nozzle 322 towards the end near the spray nozzle 322, forming an inclination guide surface. When the water storage box 320 is installed in place, the side of the locking block 3312 near the spray nozzle 322 forms a surface contact with the stop part 331, ensuring locking stability.

[0073] When installing the water storage box 320, insert the water storage box 320 into the installation cavity 311. The inclined guide surface of the snap-fit ​​block 3312 first contacts the stop part 331 of the housing 310. As the insertion depth increases, the stop part 331 generates pressure along the guide surface on the inclined guide surface. This pressure is decomposed into a component force that drives the snap-fit ​​block 3312 to retract into the sliding cavity 328, so that the snap-fit ​​block 3312 retracts automatically without manual operation by the user. In some embodiments of this application, reference is made to Figure 10 A fixing plate 329 is provided on the bottom wall of the water storage box 320; a fixing shaft 3291 is provided on the fixing plate 329, and a second elastic member 3292 is sleeved on the fixing shaft 3291. The fixing shaft 3291 passes through the pull rod 3337; one end of the second elastic member 3292 abuts against the pull rod 3337, and the other end of the second elastic member 3292 abuts against the fixing plate 329. The fixing plate 329 can be vertically fixed to the bottom wall of the water storage box 320, located on one side of the multi-link mechanism, and is used to install the fixing shaft 3291 and the second elastic member 3292. The fixing shaft 3291 is vertically arranged on the fixing plate 329 and extends along the movement direction of the pull rod 3337. The second elastic member 3292 is sleeved on the fixing shaft 3291, and the second elastic member 3292 is preferably a compression spring. One end of the second elastic member 3292 abuts against the side of the pull rod 3337, and the other end abuts against the side of the fixed plate 329. In its natural state, the second elastic member 3292 is in a slightly compressed state, applying an elastic thrust to the pull rod 3337 in a direction away from the fixed plate 329. The pull rod 3337 is provided with a through hole, and the fixed shaft 3291 passes through the through hole, allowing the pull rod 3337 to perform reciprocating linear motion along the fixed shaft 3291.

[0074] When installing the water storage box 320, the second elastic element 3292 pushes the pull rod 3337 outward, driving the telescopic locking part 332 to extend and engage with the stop part 331 via the multi-link mechanism. During disassembly, the user pulls the pull rod 3337 against the elastic force of the second elastic element 3292 towards the fixing plate 329, causing the multi-link mechanism to retract the telescopic locking part 332. After releasing the pull rod 3337, under the elastic thrust of the second elastic element 3292, the pull rod 3337 automatically resets, and the telescopic locking part 332 re-extends and engages. This structure achieves automatic reset of the pull rod 3337 and the multi-link mechanism through the second elastic element 3292, ensuring that the telescopic locking part 332 always tightly abuts against the stop part 331 after the water storage box 320 is installed, further improving stability and simplifying the operation process. In addition, the fixed shaft 3291 guides the pull rod 3337 to prevent it from deviating during movement. The second elastic element 3292 can also buffer the impact force when the pull rod 3337 moves, reduce the wear and tear of parts, and protect the structure of the mechanism.

[0075] In some embodiments of this application, reference is made to Figure 9and Figure 13 The bottom wall of the water storage box 320 is provided with a mounting groove 3201, and the telescopic snap-fit ​​part 332 is provided in the mounting groove 3201. A first through hole 3202 is provided on the groove wall of the mounting groove 3201, and the position of the first through hole 3202 is adapted to the position of the pull rod 3337. A second through hole 313 is provided on the bottom wall of the housing 310, and the position of the second through hole 313 is adapted to the position of the first through hole 3202.

[0076] For example, an additional mounting groove 3201 is provided on the bottom wall of the water storage box 320. The size of the mounting groove 3201 is adapted to the telescopic latching part 332 of the multi-link structure. The telescopic latching part 332 is completely set in the mounting groove 3201 to achieve embedded installation. A first through hole 3202 is provided on the groove wall of the mounting groove 3201 at the position corresponding to the pull rod 3337. A second through hole 313 is provided on the bottom wall of the housing 310 at the position corresponding to the first through hole 3202. The diameter of the second through hole 313 is the same as that of the first through hole 3202. When the water storage box 320 is inserted into the mounting cavity 311, the user can pull the pull rod 3337 by passing it through the first through hole 3202 and the second through hole 313 in sequence.

[0077] A mounting groove 3201 is provided on the bottom wall of the water storage box 320 for installing the telescopic latching part 332, so that the telescopic latching part 332 is embedded in the water storage box 320, without occupying external space, avoiding interference with the housing 310 or other components, and protecting the telescopic latching part 332 from external collision damage; the first through hole 3202 on the groove wall of the mounting groove 3201 is matched with the second through hole 313 on the bottom wall of the housing 310, providing a precise installation and movement channel for the pull rod 3337, ensuring that the user can pull the pull rod 3337 when using it, and improving the sealing and reliability of the overall structure.

[0078] In some embodiments of this application, reference is made to Figure 11 and Figure 12The water storage box 320 also contains an atomizing chamber 323, which is connected to the spray nozzle 322. At least one atomizing element 326 is disposed within the atomizing chamber 323, and the atomizing element 326 is connected to the water storage chamber 321. In one specific embodiment, two atomizing chambers 323 are provided, arranged symmetrically and both located on the side of the water storage chamber 321 closest to the spray nozzle 322. A portion of the water storage chamber 321 is located between the two atomizing chambers 323, and another portion is located on the side of the two atomizing chambers 323 furthest from the spray nozzle 322. In other words, the water storage box 320 has two symmetrically arranged atomizing chambers 323 inside, corresponding to the position of the spray nozzle 322. Both atomizing chambers 323 are located on the side of the water storage chamber 321 near the spray nozzle 322. A part of the water storage chamber 321 is embedded between the two atomizing chambers 323 to form an intermediate water storage area, and the other part extends to the side of the two atomizing chambers 323 away from the spray nozzle 322 to form a main water storage area. The intermediate water storage area and the main water storage area are interconnected to ensure the water circulation supply.

[0079] In addition, refer to Figure 11 A power unit is also provided between the water storage box 320 and the housing 310 to provide power to the atomizing element 326. The output end of the power unit is set on the side wall of the water storage box 320 through a spring. A first cover plate 325 is provided on the water storage cavity 321 to seal the water storage cavity. A wiring groove 3251 is provided on the side of the first cover plate 325 away from the water storage cavity 321. Multiple wires are provided in the wiring groove 3251. One end of the multiple wires is electrically connected to the spring of the power unit, and the other end of the wires is electrically connected to the atomizing element 326 or the lighting element 334 respectively.

[0080] The atomizing element 326 can be an ultrasonic atomizer. The ultrasonic atomizer is installed on the side wall of the atomizing chamber 323 away from the spray nozzle 322 by means of mounting base or screw locking. The ultrasonic atomizer is connected to the water storage chamber 321 to ensure that the water in the water storage chamber 321 can flow into the atomizer continuously and stably.

[0081] In addition, a water inlet is provided on the upper surface of the first cover plate 325, through which water can be injected into the humidifying water box. The water inlet is connected to the water storage chamber 321. The water inlet is sealed by a water injection piston 327.

[0082] A separate atomizing chamber 323 is constructed within the water storage box 320, housing at least one atomizing element 326. The atomizing element 326 is connected to the water storage box 321, and the spray nozzle 322 is connected to the atomizing chamber 323. This achieves an integrated layout of the atomizing structure while ensuring humidification effect and reliability. The atomizing chamber 323 provides an independent and stable installation space for the atomizing element 326, preventing it from shaking or shifting during disassembly and transportation of the water storage box 320. Simultaneously, it isolates the atomizing element 326 from the direct impact of water within the water storage box 321, extending its service life.

[0083] In some embodiments of this application, reference is made to Figure 11 The humidifier 300 also includes an illumination element 334; the illumination element 334 is disposed within the water storage chamber 321 and fixed to the upper wall of the water storage chamber 321. Specifically, the illumination element 334 is located on the top wall of the water storage chamber 321 between the two atomizing chambers 323. By adding an illumination element 334 fixed to the upper wall within the water storage chamber 321, the interior of the water storage chamber 321 can be directly illuminated, allowing users to quickly observe the remaining water level without disassembling the water storage box 320 to determine whether water needs to be added. Combined with the quick-unlocking structure of the water storage box 320, the water replenishment operation process is further simplified.

[0084] Reference Figure 2 , Figure 8 , Figure 9 and Figure 12 To facilitate users' real-time monitoring of the water level and water quality in the water storage chamber 321, an observation hole 324 is provided on the side of the middle water storage area of ​​the water storage box 320. The observation hole 324 has a circular, elliptical, or rectangular structure and is directly connected to the interior of the water storage chamber 321. The inner wall of the observation hole 324 has a stepped mounting groove. The viewing plate is fixed in the mounting groove by snapping or bonding. The viewing plate can be made of high-transmittance PC material and the surface is treated with an anti-fog coating to ensure the sealing of the water storage chamber 321 and to clearly observe the remaining water level and water cleanliness, avoiding the humidification effect being affected by turbid water or low water level.

[0085] An observation hole 324 communicating with the water storage chamber 321 is provided on the water storage box 320 and a transparent plate is embedded therein. The transparent plate not only ensures the sealing of the water storage chamber 321 to prevent water leakage, but also allows users to directly observe the remaining water level and water quality through the observation hole 324 without disassembling the water storage box 320. Users can decide whether to add water or clean according to the observation results, avoiding blind disassembly and simplifying the operation process.

[0086] In some embodiments of this application, reference is made to Figure 2 , Figure 8 and Figure 12 The extension direction of the spray nozzle 322 is the same as the length direction of the water storage box 320. The spray nozzle 322 is an opening structure for directional spraying of water mist, and it can be implemented with different cross-sectional shapes such as circular, elliptical, or slit-shaped. Its purpose is to controllably deliver the atomized water mist into the receiving cavity 101. Since there are two atomizing cavities 323, there are also two spray nozzles 322, and the spray nozzles 322 are connected to the atomizing cavities 323.

[0087] As a specific implementation, the water storage box 320 can be specifically designed as a long strip structure, with its length extending along the width direction of the door 200; the spray nozzle 322 can be specifically set as a slit-like opening extending along the length direction of the water storage box 320, so that the water mist is uniformly sprayed into the receiving cavity 101 in a linear manner.

[0088] By setting the extension direction of the spray nozzle 322 to be the same as the length direction of the water storage box 320, the water mist can be spread evenly across the entire width of the cavity, avoiding the problem of local humidity imbalance caused by random spray direction. This can significantly improve the humidification uniformity and coverage of the refrigerator cavity 101, and make the atomized water mist diffuse linearly along the length direction of the water storage box 320. This can be adapted to the installation space layout of the refrigerator door 200, allowing the water mist to more comprehensively cover the horizontal area of ​​the cavity 101 and avoid the problem of uneven local humidification.

[0089] A refrigerator is also disclosed in a second aspect of the embodiments of this application, with reference to Figure 1 The device includes a housing 100 and a door 200. The housing 100 is divided into multiple independent compartments 101 by partitions for storing different ingredients. The door 200 is rotatably mounted on the housing 100 to close or open the compartments 101. The door 200 is rotatably connected to one side of the housing 100 via a hinge assembly. When closed, the door 200 fits against the sealing surface of the housing 100, achieving sealed insulation of the compartments 101. When open, the door 200 allows easy access to the compartments 101 for food storage. Furthermore, a humidifier 300 is installed on the door 200 to humidify the compartments 101. A shelf is provided on the inner wall of the door 200, and the humidifier 300 is placed within the shelf. Its installation height corresponds to the central area of ​​the compartments 101, ensuring that water mist can be evenly distributed to all corners of the compartments 101.

[0090] Among them, reference Figure 2 and Figure 8The humidifier 300 includes a housing 310 and a water storage box 320. An installation cavity 311 is constructed within the housing 310, with its opening facing the outside of the door 200 for easy assembly and disassembly of the water storage box 320. The water storage box 320 is disposed within the installation cavity 311, and its interior forms a water storage chamber 321 for storing humidifying water. An elongated spray nozzle 322 is constructed on the front end face of the water storage box 320, extending in the same direction as the length of the water storage box 320. The spray nozzle 322 is positioned facing the refrigerator's receiving cavity 101, ensuring that the atomized water mist can be directionally sprayed into the receiving cavity 101. The water storage box 320 has two symmetrically arranged atomizing chambers 323 corresponding to the spray nozzle 322. Both atomizing chambers 323 are located on the side of the water storage chamber 321 near the spray nozzle 322. A part of the water storage chamber 321 is embedded between the two atomizing chambers 323 to form an intermediate water storage area, and the other part extends to the side of the two atomizing chambers 323 away from the spray nozzle 322 to form a main water storage area. The intermediate water storage area and the main water storage area are interconnected to ensure water circulation supply. Each atomizing chamber 323 is fixedly installed with an ultrasonic atomizer. The ultrasonic atomizer is fixed to the side wall of the atomizing chamber 323 away from the spray nozzle 322 by a buckle 334. When the ultrasonic atomizer is working, it atomizes the water in the water storage chamber 321 into micron-sized water mist. Under the action of air pressure, the water mist is sprayed directionally into the receiving cavity 101 through the spray nozzle 322 to achieve humidity regulation.

[0091] The humidifier 300 may further include a locking mechanism 330 for fixing the water storage box 320 within the mounting cavity 311. The locking mechanism 330 includes a stop, a telescopic latching part, and a telescopic mechanism. The stop is located on both side walls of the water storage box 320, protruding outwards or recessed inwards to form an engaging structure. The telescopic latching part is located on the inner surface of the housing 310, corresponding to the stop, and can telescopically move relative to the housing 310, cooperating with the stop to lock or unlock the water storage box 320 from the housing 310. The telescopic mechanism is drively connected to the telescopic latching part; when the water storage box 320 is pulled out of the mounting cavity 311, the telescopic mechanism drives the telescopic latching part to move closer to the housing 310, disengaging the two.

[0092] During installation, the water storage box 320 is inserted into the mounting cavity 311 of the housing 310, and the telescopic locking part extends out and engages with the stop part on the water storage box 320 to achieve fixation; during disassembly, the telescopic mechanism is operated to drive the telescopic locking part to retract and approach the housing 310, thereby releasing the engagement with the stop part and allowing the water storage box 320 to be pulled out. The stop is located on the side wall of the water storage box 320, and the telescopic latch is located on the inner surface of the housing 310. The reverse-layout locking mechanism 330 also achieves reliable fixation and convenient disassembly of the water storage box 320 and the housing 310, adapting to different humidification device 300 installation scenarios. The telescopic mechanism drives the telescopic latch to move closer to the housing 310 to unlock. The operation logic is clear. The user can complete the unlocking action by pulling out the water storage box 320 without additional tools. This ensures that when the housing 310 is installed on the door 200, the water storage box 320 can still maintain the advantages of stable installation and convenient disassembly. At the same time, the design of the spray nozzle 322 spraying water mist towards the receiving cavity 101 ensures uniform humidification and meets the humidification needs of fruits and vegetables in the refrigerator, taking into account both structural adaptability and functional practicality.
