Description

Technical Field

[0001] This application relates to the field of consumer goods technology, and more specifically to a fan. Background Technology

[0002] In daily life, fans are one of the most commonly used cooling devices, especially in summer or in poorly ventilated indoor environments, where their importance is self-evident. However, traditional fans typically have a fixed structure and a large size, which means they take up a lot of space when not in use, especially in environments with limited living space, such as small apartments, offices, or dormitories. Furthermore, the installation and disassembly of traditional fans are relatively cumbersome, making it difficult to flexibly adjust their position according to actual needs, further limiting their convenience and flexibility. To overcome these limitations of traditional fans, retractable fans have gradually emerged on the market. The design concept of these fans is to optimize the structure so that they can be easily stored when not in use, reducing space occupation, while quickly unfolding to restore their normal function when needed. This not only improves space utilization efficiency but also enhances the fan's flexibility and practicality. Therefore, most existing fans adopt a folding storage design. While this can reduce storage volume to some extent, the irregular shape of the fan means that the folded fan is still relatively large, failing to achieve a slim and compact storage effect. Furthermore, the folded fan requires additional dust bags or storage boxes for protection, increasing the complexity and cost of storage. In addition, traditional fan storage methods usually require users to manually disassemble or fold multiple parts, a cumbersome process that can easily damage the fan's structure and shorten its lifespan. Although some fans come with storage stands or boxes, these accessories often take up extra space and are not flexible enough for transport and storage.

[0003] To address the aforementioned issues, for example, the utility model with authorization announcement number CN207161384U discloses a fan that is easy to store, including a housing and a fan body. The housing has an opening at the top for inserting or removing the fan body. The fan body has movable rails on its left and right sides, and the inner wall of the housing has fixed rails that cooperate with the movable rails. The top of the fan body is fixed with a cover that can close the housing, and the cover has a handle. The fan body includes a back plate with a positioning hole, and the housing has a horizontally arranged fixing hole with a positioning strip inside the fixing hole. The positioning strip is rotatably connected to the housing via a pin. When the fan body is raised to its highest position, the positioning hole and the fixing hole are aligned. In this technical solution, the fan body is pulled out and stored from the housing by the cooperation of movable rail and fixed rail. Although this solves the storage and dust prevention problem of existing folding fans, users need to apply a lot of force when manually pulling out the fan body. Frequent manual pulling is not only laborious, but also difficult for users with limited height to pull out the fan motor independently, resulting in many usage problems. Summary of the Invention

[0004] The technical problem to be solved by this application is to provide a fan that achieves the switching between storage and use states by setting the first housing to slide and extend relative to the second housing, and achieves the function of the first housing driving the fan blades to extend automatically through the cooperation of the first elastic element and the locking structure, making it easier to use.

[0005] This application provides a fan, including a first housing, on which fan blades and a motor are mounted, the motor driving the fan blades to rotate, and a second housing. The first housing is slidably mounted inside the second housing, and the first housing can extend and retract relative to the second housing by sliding. A locking structure and a first elastic member are provided between the first housing and the second housing. The locking structure is used to limit the sliding of the first housing within the second housing, and the locking structure is unlocked by force to allow the first housing to slide out of the second housing under the action of the first elastic member.

[0006] In this technical solution, the first housing is equipped with fan blades and a motor to realize the basic functions of a fan. The second housing serves as a storage container, with the first housing slidably installed inside it. The sliding extension and retraction allows for switching between storage and use modes. The telescopic design of the first and second housings significantly reduces the fan's size in the storage state, occupying less space and facilitating storage and portability. In the storage state, the second housing provides dust protection, preventing dust accumulation or damage to the fan blades and motor when idle. A locking structure confines the first housing within the second housing, ensuring the fan's stability in the storage state. A first elastic element provides power for the sliding of the first housing. When the locking structure is unlocked, the elastic force of the first elastic element pushes the first housing to slide out automatically, reducing the need for manual pulling and simplifying operation. Through the cooperation of the first elastic element and the locking structure, the first housing enables the fan blades to extend automatically, eliminating the need for manual pulling and greatly improving operational convenience. Furthermore, the unlocking mechanism is simple and easy to operate, allowing users to easily unfold and retract the fan, making it more effortless in actual use.

[0007] As an improvement, a power supply component and a switch component are installed inside the second housing. Both the motor and the switch component are electrically connected to the power supply component. The motor is powered by the power supply component to drive the fan blades to rotate. The switch component is used to control the connection or disconnection between the motor and the power supply component. In this technical solution, the power supply component, installed inside the second housing, provides a stable power supply to the motor. The power supply component includes, but is not limited to, a lithium battery, facilitating maintenance and replacement. The switch component, also installed inside the second housing, controls the circuit connection between the motor and the power supply component, thereby achieving on / off control of the fan. The power supply component, switch component, and motor are sequentially connected via power lines to form a series circuit. Integrating the power supply component and switch component within the second housing makes the overall structure of the fan more compact, reduces the complexity of external wiring, and improves the product's aesthetics and portability.

[0008] As an improvement, the bottom of the first housing is provided with a connecting shaft adapted to the switch assembly. The first housing slides back to allow the connecting shaft to abut against the switch assembly, causing the switch assembly to disconnect the motor from the power supply assembly. Conversely, the first housing slides out to disengage the connecting shaft from the switch assembly, allowing the switch assembly to connect the motor to the power supply assembly. In this technical solution, the first housing slides back into the second housing and abuts against the switch assembly via the connecting shaft at the bottom, thereby triggering the switch assembly and controlling the disconnection of the motor from the power supply assembly. Sliding Extension: When the first housing slides out, the connecting shaft disengages from the switch assembly, triggering the switch assembly and controlling the connection between the motor and the power supply assembly, thus enabling the fan to start automatically. Linking the sliding extension and retraction of the first housing with the power on / off of the motor reduces manual operation by the user, allowing the fan to be used immediately after unfolding. It also reduces misoperation caused by improper manual operation, such as forgetting to turn off the power or accidentally pressing the switch, improving the user experience. The connecting shaft at the bottom of the first housing works in conjunction with the switch assembly to ensure the accuracy of the triggering action. Users do not need to manually turn the fan on or off; they can automatically start and stop the fan simply by sliding the first housing, reducing user intervention and making the fan use more intelligent and effortless.

[0009] As an improvement, the switch assembly is provided with a switch shaft and a switch sleeve. The switch sleeve is connected to a second elastic element. When the first housing slides back into the second housing, the first housing slides and abuts against the switch sleeve. The switch shaft is pressed down by force, causing the switch assembly control motor to disconnect from the power supply assembly. When the first housing slides out of the second housing, the first housing slides and disengages from the switch sleeve. The switch sleeve drives the switch shaft to reset under the action of the second elastic element, so that the switch assembly control motor is connected to the power supply assembly. In this technical solution, the switch shaft is a key component for realizing circuit switching. The switch assembly also includes a PCB board. The switch shaft cooperates with the PCB board to realize the circuit switching control of the switch assembly. The switch sleeve protects and drives the switch shaft. A second elastic element is set on the switch shaft. One end of the second elastic element abuts against the switch sleeve, and the other end abuts against the switch assembly. The function of the second elastic element is to reset the switch shaft after it is pressed down, ensuring that the switch assembly can automatically return to its initial state after the external force is removed. When the first housing slides back into the second housing, the first housing abuts against the switch sleeve, applying downward pressure to the switch shaft. The downward movement of the switch shaft triggers the switch assembly. The connection between the motor and the power supply is disconnected, enabling the fan to automatically shut down. When the first housing slides out of the second housing, the first housing disengages from the switch sleeve. Under the action of the second elastic element, the switch sleeve drives the switch shaft to reset to its initial state, thereby triggering the switch assembly to connect the motor and the power supply, causing the fan to turn on automatically. Users do not need to manually operate the switch; they can simply slide the first housing to automatically turn the fan on and off, reducing user intervention and greatly simplifying the operation process, thus improving the user experience. On the other hand, the second elastic element can also buffer the force of the first housing on the switch sleeve, reducing mechanical impact and further improving the service life of the device.

[0010] As an improvement, a partition is provided inside the second housing, dividing the second housing into a first chamber and a second chamber arranged vertically. The first housing is slidably installed in the first chamber, and the power supply assembly and switch assembly are both installed in the second chamber. The partition has a through hole for the switch sheath to pass through, and one end of the switch sheath passes through the through hole and is inserted into the first chamber to mate with the first housing. In this technical solution, the partition divides the internal space of the second housing into a first chamber and a second chamber arranged vertically, allowing the first housing, power supply assembly, and switch assembly to be installed in different chambers, avoiding mutual interference, reducing space waste, and improving the overall compactness of the product. The power supply assembly and switch assembly are installed in the second chamber, facilitating maintenance and replacement, enabling centralized management of power and control functions, and ensuring the stability and safety of the circuit system. The through hole on the partition allows the switch sheath to directly interact with the sliding movement of the first housing, achieving mechanical triggering and improving the reliability and stability of circuit control.

[0011] As an improvement, a power indicator light is installed on the second housing. This power indicator light is electrically connected to the power supply component and is used to display the connection status between the power supply component and the motor. In this technical solution, the power indicator light is installed on the second housing, making it easily observable by the user and preventing interference or damage caused by the sliding motion of the first housing. The power indicator light is connected to the power supply component via a circuit, enabling it to monitor the power supply component's status in real time and display the information to the user through light signals. When the power supply component is connected to the motor (i.e., the motor is in operation), the indicator light illuminates; when the power supply component is disconnected from the motor (i.e., the motor is stopped), the indicator light turns off. Through the light signals, the user can intuitively understand the fan's power status without manually checking or guessing whether the motor is running, reducing operational steps and improving ease of use.

[0012] As an improvement, the locking structure is an elastic arm structure set on the side wall of the first housing, and the second housing is provided with a buckle hole for the locking structure to pass through. The locking structure is snapped into the buckle hole to make the first housing slide and lock. When the locking structure is subjected to force, it disengages from the buckle hole through elastic action to make the first housing slide and unlock. In this technical solution, the locking structure adopts the form of an elastic arm, utilizing the properties of elastic materials to allow the locking structure to deform under force and return to its original shape after the force is released. A buckle hole is provided on the second housing to cooperate with the locking structure. When the first housing slides to the preset position, the locking structure, under its own elastic force, engages with the buckle hole of the second housing, forming a snap connection and locking the first and second housings. The locking structure can also protrude through the buckle hole, making it easy for the user to unlock. When the user presses the locking structure in the buckle hole, the locking structure undergoes elastic deformation under force and disengages from the buckle hole, completing the unlocking. The first housing automatically slides out relative to the second housing under the action of the first elastic element, realizing a one-button unlock and power-on function without the need for additional user operation. It has the advantages of convenient operation, stable structure, high security, and optimized user experience.

[0013] As an improvement, the side wall of the second housing is provided with a sliding groove adapted to the locking structure. The sliding groove slides with the locking structure to guide the sliding of the first housing. The latching hole is located at one end of the sliding groove, and the other end of the sliding groove is used to limit the sliding range of the locking structure. In this technical solution, by providing a sliding groove on the second housing, the sliding groove guides the sliding of the locking structure, ensuring that the first housing moves along a predetermined trajectory during the sliding process, avoiding deviation or jamming. The latching hole is located at one end of the sliding groove to cooperate with the locking structure to realize the locking function of the first housing. The other end of the sliding groove is designed to limit the sliding range of the locking structure, preventing the locking structure from sliding excessively and causing the first housing to detach from the second housing, further enhancing the reliability of the structure.

[0014] As an improvement, the top of the second housing is provided with an opening for the sliding and retracting of the first housing, and the top of the first housing is provided with a top plate adapted to the opening. When the first housing slides back into the second housing, the top plate closes the opening to be flush with the top of the second housing. In this technical solution, the opening at the top of the second housing ensures that the first housing can smoothly enter and exit the second housing. The top plate at the top of the first housing has a size and shape adapted to the opening. When the first housing slides back into the second housing, the top plate can completely close the opening and be flush with the top of the second housing, forming a flat surface. This is not only aesthetically pleasing, making the entire device look simpler and more beautiful when stored, reducing obtrusiveness, but also reduces the entry of dust and debris into the interior of the second housing, extending its service life. The overall volume is smaller when stored, making it easier to store and carry.

[0015] As an improvement, at least two first elastic elements and at least two locking structures are symmetrically distributed. A mounting bracket adapted to the motor is provided inside the first housing, and the motor is mounted inside the first housing via the mounting bracket. In this technical solution, the first elastic element is preferably a spring, used to provide elastic force so that the first housing can automatically slide out after unlocking, realizing a one-button unlock and power-on function. The symmetrical distribution of at least two first elastic elements ensures that the first housing is subjected to uniform force during sliding, avoiding offset or jamming caused by force on one side. The locking structure, through its elastic arm, cooperates with the buckle hole on the second housing to realize the locking and unlocking functions of the first housing. The symmetrical distribution of at least two locking structures improves the stability and reliability of locking, ensuring that the first housing will not accidentally slide out due to external force when stored. The symmetrical distribution of the first elastic elements and the locking structure ensures the stability of the first housing during sliding and locking, enhancing the safety of product use. The mounting bracket inside the first housing ensures that the motor can be securely installed inside the first housing, avoiding vibration and displacement during operation, and also reducing the impact force of the motor on the first housing during operation, extending the product's service life.

[0026] like Figures 1 to 5As shown, this application discloses a fan, including a first housing 1, on which fan blades 2 and a motor 3 are mounted. The motor 3 drives the fan blades 2 to rotate. It also includes a second housing 4, in which the first housing 1 is slidably installed. The first housing 1 can extend and retract relative to the second housing 4 by sliding. The fan blades 2 and the motor 3 are mounted on the first housing 1 to realize the basic functions of the fan. The second housing 4 serves as a storage container. The first housing 1 is slidably installed in the second housing 4. The sliding extension and retraction realize the switching between storage and use states. The extension and retraction design of the first housing 1 and the second housing 4 makes the fan volume significantly reduced in the storage state, occupying less space and making it easy to store and carry. In the storage state, the second housing 4 can play a dust protection role, preventing the fan blades 2 and the motor 3 from accumulating dust or being damaged when idle.

[0027] like Figure 2 and Figure 4 As shown, there is a locking structure 11 and a first elastic element 5 between the first housing 1 and the second housing 4. The locking structure 11 is used to limit the sliding of the first housing 1 within the second housing 4 to ensure the stability of the fan in the retracted state. The first elastic element 5 provides power for the sliding of the first housing 1. When the locking structure 11 is unlocked by force, the first housing 1 slides out of the second housing 4 under the action of the first elastic element 5. When the locking structure 11 is unlocked by force, the elastic force of the first elastic element 5 pushes the first housing 1 to slide out automatically, reducing the step of manual pulling by the user and reducing the difficulty of operation. Through the cooperation of the first elastic element 5 and the locking structure 11, the function of the first housing 1 driving the fan blade 2 to extend automatically is realized. The user does not need to manually pull the fan, which greatly improves the convenience of operation. At the same time, the unlocking mechanism is simple and easy to operate. The user can complete the unfolding and retraction of the fan through simple operation, which is more labor-saving in actual use.

[0028] More specifically, such as Figure 2 and Figure 4 As shown, a power supply assembly 6 and a switch assembly 7 are installed inside the second housing 4. The motor 3 and the switch assembly 7 are both electrically connected to the power supply assembly 6. The motor 3 is powered by the power supply assembly 6 to drive the fan blades 2 to rotate. The switch assembly 7 is used to control the connection or disconnection between the motor 3 and the power supply assembly 6. The power supply assembly 6 is installed inside the second housing 4 to provide a stable power supply to the motor 3. The power supply assembly 6 includes, but is not limited to, a lithium battery, which is convenient for maintenance and replacement. The switch assembly 7 is installed inside the second housing 4 to control the circuit connection between the motor 3 and the power supply assembly 6, thereby realizing the on / off control of the fan. The power supply assembly 6, the switch assembly 7, and the motor 3 are connected in sequence through a power line to form a series circuit. Integrating the power supply assembly 6 and the switch assembly 7 inside the second housing 4 makes the overall structure of the fan more compact, reduces the complexity of external wiring, and improves the aesthetics and portability of the product.

[0029] More specifically, such as Figure 2 and Figure 4 As shown, the bottom of the first housing 1 is provided with a connecting shaft 12 adapted to the switch assembly 7. The first housing 1 slides back to make the connecting shaft 12 abut against the switch assembly 7, so that the switch assembly 7 controls the motor 3 to disconnect from the power supply assembly 6. The first housing 1 slides out to make the connecting shaft 12 disengage from the switch assembly 7, so that the switch assembly 7 controls the motor 3 to connect with the power supply assembly 6. The first housing 1 slides back into the second housing 4 and abuts against the switch assembly 7 through the connecting shaft 12 at the bottom, thereby triggering the switch assembly 7 and controlling the motor 3 to disconnect from the power supply assembly 6. Sliding Extension: When the first housing 1 slides out, the connecting shaft 12 disengages from the switch assembly 7, thereby triggering the switch assembly 7, which in turn controls the connection between the motor 3 and the power supply assembly 6, realizing the automatic start of the fan. The sliding extension and retraction of the first housing 1 is linked with the power on and off of the motor 3, reducing the need for manual operation by the user. This allows the fan to be used immediately after unfolding, while also reducing misoperation caused by improper manual operation, such as forgetting to turn off the power or accidentally touching the switch, thus improving the user experience. The connecting shaft 12 at the bottom of the first housing 1 works in conjunction with the switch assembly 7 to ensure the accuracy of the triggering action. Users do not need to manually turn the fan on or off; they can simply slide the first housing 1 to achieve automatic start and stop of the fan, reducing user intervention in fan operation and making the use of the fan more intelligent and effortless.

[0030] More specifically, such as Figure 2 and Figure 4 As shown, the switch assembly 7 is provided with a switch shaft 71 and a switch sleeve 72. The switch sleeve 72 is connected to a second elastic element 73. The switch shaft 71 is a key component for realizing the circuit switching. The switch assembly 7 also includes a PCB board 74. The switch shaft 71 and the PCB board 74 cooperate to realize the circuit switching control of the switch assembly 7. The switch sleeve 72 plays the role of protecting and driving the switch shaft 71. The second elastic element 73 is provided and fitted on the switch shaft 71. One end of the second elastic element 73 abuts against the switch sleeve 72, and the other end of the second elastic element 73 abuts against the switch assembly 7. The function of the second elastic element 73 is to reset the switch shaft 71 after it is pressed down by force, so that the switch assembly 7 can automatically return to the initial state after the external force is lost.

[0031] When the first housing 1 slides back into the second housing 4, as Figure 3 and Figure 4 As shown, the first housing 1 abuts against the switch sleeve 72, applying downward pressure to the switch shaft 71. The downward movement of the switch shaft 71 triggers the switch assembly 7 to disconnect the connection between the motor 3 and the power supply assembly 6, thereby automatically shutting off the fan. When the first housing 1 slides out of the second housing 4, as... Figure 1 and Figure 2As shown, the first housing 1 disengages from the switch sleeve 72. Under the action of the second elastic element 73, the switch sleeve 72 drives the switch shaft 71 to reset and return to its initial state, thereby triggering the switch assembly 7 to connect the motor 3 and the power supply assembly 6, so that the fan can be turned on automatically. The user does not need to manually operate the switch, but only needs to slide the first housing 1 to realize the automatic opening and closing of the fan, which reduces the user's intervention in the operation of the fan, greatly simplifies the operation steps, and improves the user experience. On the other hand, the second elastic element 73 can also buffer the force of the first housing 1 on the switch sleeve 72, reduce mechanical impact, and further improve the service life of the device.

[0032] More specifically, such as Figure 2 , Figure 4 and Figure 5 As shown, a partition 41 is provided inside the second housing 4, which divides the second housing 4 into a first chamber and a second chamber distributed vertically. The first housing 1 is slidably installed in the first chamber, and the power supply assembly 6 and the switch assembly 7 are both installed in the second chamber. The partition 41 is provided with a through hole 411 for the switch sleeve 72 to pass through. One end of the switch sleeve 72 passes through the through hole 411 and is inserted into the first chamber to cooperate with the first housing 1. The partition 41 divides the internal space of the second housing 4 into the first chamber and the second chamber distributed vertically, so that the first housing 1, the power supply assembly 6, and the switch assembly 7 are installed in different chambers, avoiding mutual interference, reducing space waste, and improving the overall compactness of the product. The power supply assembly 6 and the switch assembly 7 are installed in the second chamber, which facilitates maintenance and replacement, realizes centralized management of power supply and control functions, and ensures the stability and safety of the circuit system. The through hole 411 on the partition 41 allows the switch sleeve 72 to directly interact with the sliding movement of the first housing 1, realize mechanical triggering, and improve the reliability and stability of circuit control.

[0033] More specifically, such as Figures 2 to 4 As shown, a power indicator light 8 is installed on the second housing 4. The power indicator light 8 is electrically connected to the power supply component 6. The power indicator light 8 is used to display the connection status between the power supply component 6 and the motor 3. The power indicator light 8 is installed on the second housing 4 so that the indicator light can be easily observed by the user, while avoiding interference or damage to the indicator light caused by the sliding movement of the first housing 1. The power indicator light 8 is connected to the power supply component 6 through a circuit, so that the indicator light can monitor the status of the power supply component 6 in real time and display the information to the user through light signals. When the power supply component 6 is connected to the motor 3 (i.e., the motor 3 is in the working state), the indicator light is on. When the power supply component 6 is disconnected from the motor 3 (i.e., the motor 3 is in the stopped state), the indicator light is off. Through light signals, the user can intuitively understand the power status of the fan without manually checking or guessing whether the motor 3 is running, reducing operation steps and improving the convenience of use.

[0034] More specifically, such as Figure 2 and Figure 4 As shown, the locking structure 11 is an elastic arm structure set on the side wall of the first housing 1. The second housing 4 is provided with a buckle hole 42 for the locking structure 11 to pass through. The locking structure 11 is snapped into the buckle hole 42 to lock the first housing 1. When the locking structure 11 is subjected to force, it disengages from the buckle hole 42 through elastic action to unlock the first housing 1. The locking structure 11 adopts the form of an elastic arm, utilizing the properties of elastic material, so that the locking structure 11 can deform under force and return to its original shape after the force is released. The buckle hole 42 is provided on the second housing 4 to cooperate with the locking structure 11. When the first housing 1 slides to the preset position, The locking structure 11, under its own elastic force, engages with the buckle hole 42 of the second housing 4, forming a buckle connection and locking the first housing 1 and the second housing 4. The locking structure 11 can also protrude through the buckle hole 42, making it easy for the user to unlock. When the user presses the locking structure 11 in the buckle hole 42, the locking structure 11 undergoes elastic deformation under force and disengages from the buckle hole 42, completing the unlocking. The first housing 1 automatically slides out relative to the second housing 4 under the action of the first elastic element 5, realizing the one-button unlocking and power-on function without the need for additional user operation. It has the advantages of convenient operation, stable structure, high security, and optimized user experience.

[0035] More specifically, such as Figure 2 , Figure 4 and Figure 5 As shown, the side wall of the second housing 4 is provided with a groove 43 adapted to the locking structure 11. The groove 43 slides with the locking structure 11 to guide the sliding of the first housing 1. A latching hole 42 is provided at one end of the groove 43, and the other end of the groove 43 is used to limit the sliding range of the locking structure 11. By providing the groove 43 on the second housing 4, the groove 43 is used to guide the sliding of the locking structure 11, ensuring that the first housing 1 moves along a predetermined trajectory during the sliding process, avoiding deviation or jamming. The latching hole 42 is provided at one end of the groove 43 for engaging with the locking structure 11. In conjunction with the locking mechanism, the first housing 1 is locked. The other end of the slide groove 43 is designed to limit the sliding range of the locking structure 11, preventing the locking structure 11 from sliding excessively and causing the first housing 1 to detach from the second housing 4, thus further enhancing the reliability of the structure. The slide groove 43 is provided with a positioning protrusion 44 that is adapted to the locking structure 11. The positioning protrusion 44 is located near the other end of the slide groove 43. The positioning protrusion 44 cooperates with the locking structure 11 to help the first housing 1 maintain its extended state and provides support for the first housing 1, making the first housing 1 more stable in use.

[0036] More specifically, such as Figure 2 , Figure 4 and Figure 5As shown, the top of the second housing 4 is provided with an opening 45 for the sliding extension and retraction of the first housing 1. The top of the first housing 1 is provided with a top plate 13 adapted to the opening 45. When the first housing 1 slides back into the second housing 4, the top plate 13 covers the opening 45 to be flush with the top of the second housing 4. The opening 45 on the top of the second housing 4 ensures that the first housing 1 can smoothly enter and exit the second housing 4. The size and shape of the top plate 13 are adapted to the opening 45. When the first housing 1 slides back into the second housing 4, the top plate 13 can completely cover the opening 45 and be flush with the top of the second housing 4, forming a flat surface. This is not only aesthetically pleasing, making the entire device look simpler and more beautiful when stored, reducing the abruptness, but also reducing the entry of dust and debris into the interior of the second housing 4, extending its service life. The overall volume is smaller when stored, making it easier to store and carry.

[0037] More specifically, such as Figure 2 and Figure 4 As shown, at least two first elastic elements 5 are symmetrically distributed, and at least two locking structures 11 are symmetrically distributed. The first elastic elements 5 are preferably springs, used to provide elastic force so that the first housing 1 can automatically slide out after unlocking, realizing a one-button unlocking and power-on function. The symmetrical distribution of at least two first elastic elements 5 ensures that the first housing 1 is subjected to uniform force during sliding, avoiding offset or jamming caused by force on one side. The locking structure 11, through its elastic arm, cooperates with the latch hole 42 on the second housing 4 to realize the locking and unlocking functions of the first housing 1. The symmetrical distribution of at least two locking structures 11 improves the stability of the locking mechanism. Reliability is ensured by the fact that the first housing 1 will not accidentally slide out due to external force when it is in the stored state. The symmetrical distribution of the first elastic element 5 and the locking structure 11 ensures the stability of the first housing 1 during the sliding and locking process, enhancing the safety of product use. The first housing 1 is provided with a mounting bracket 14 adapted to the motor 3. The motor 3 is installed in the first housing 1 through the mounting bracket 14. The mounting bracket 14 in the first housing 1 ensures that the motor 3 can be stably installed in the first housing 1, avoiding vibration and displacement during operation. It also reduces the impact force of the motor 3 on the first housing 1 during operation, extending the service life of the product.
