Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a handle device and a mobile air conditioner having the same. Background Art

[0002] In order to facilitate the movement of household appliances such as dehumidifiers and portable air conditioners, handles are usually installed on the housing of such appliances to facilitate user movement. However, most household appliance handles are currently concave and open. When in use, the concave part of such handles is not only easy to collect dust and dirt, but also has a poor overall aesthetic appearance. Summary of the Invention

[0003] The first object of the present invention is to provide a handle device to solve the technical problem that the handles of existing mobile air conditioners are prone to collecting dust and dirt.

[0004] The handle device provided by the present invention is arranged on the shell of a household appliance, and the shell is provided with a finger-receiving space and an opening connected to the finger-receiving space. The handle device includes a handle cover rotatably arranged in the finger-receiving space, a positioning rib fixedly arranged in the finger-receiving space, and a reset assembly, wherein the handle cover has an open state exposing the finger-receiving space and a closed state closing the opening, in which the handle cover is coplanar with the outer surface of the shell; the positioning rib is used to rotate the handle cover around a set direction to the open state; and the reset assembly is used to restore the handle cover to the closed state.

[0005] The use of the handle device in a mobile air conditioner is used as an example for explanation. By providing a handle device mainly composed of a handle cover, a positioning rib, and a reset assembly, when the mobile air conditioner is not being transported or moved, the handle cover is in a closed state with an open opening. At this time, the handle cover is coplanar with the outer surface of the housing. When the mobile air conditioner needs to be transported or moved, the handle cover can be rotated to expose the finger accommodating space, forming a transport force application point at the finger accommodating space, so that the user's hand can be inserted into the finger accommodating space to carry and move the mobile air conditioner. The rotation of the handle cover can be automatic rotation achieved by a drive assembly, or manual rotation achieved by the user's hand pressing. After the mobile air conditioner is transported and moved, the handle cover will return to the closed state under the action of the reset assembly.

[0006] The arrangement of the above-mentioned handle device allows the concave finger-accommodating space to be covered by the handle cover when the mobile air conditioner does not need to be carried. At this time, the handle cover is coplanar with the outer shell, and there is no concave area on the outer surface of the mobile air conditioner. Dust and dirt will not accumulate, which solves the technical problem that the handles of existing mobile air conditioners are prone to dust and dirt accumulation. In addition, the overall aesthetics of the mobile air conditioner is ensured.

[0007] In addition, by providing positioning ribs in the finger accommodation space, the handle cover can only be rotated in the set direction when the handle cover needs to be switched from a closed state to an open state, eliminating the tedious steps of requiring the user to try to rotate the handle cover in multiple directions, saving the opening time of the handle cover and thus improving the opening efficiency of the handle cover.

[0008] Furthermore, the portion of the finger-accommodating space opposite the opening is an opening, and the handle device further includes a bottom cover that is detachably fixedly connected to the outer shell. This arrangement not only facilitates the processing and molding of the outer shell, but also enables the handle device to be detachably mounted on the outer shell, facilitating disassembly and maintenance of the handle device.

[0009] Furthermore, the bottom cover is provided with a connection hole for connecting to the internal structure of the household appliance. This arrangement allows the air duct assembly to share the carrying force acting on the handle when transporting the portable air conditioner, thereby using the air duct assembly to bear the weight and reducing the force acting on the outer shell.

[0010] Furthermore, the handle cover is rotatably mounted to the housing via pins at both ends along its rotation axis. The handle device further includes a drive assembly, which is in driving connection with the handle cover and is configured to drive the handle cover to switch between the open and closed states. This arrangement, in which the handle cover is opened and closed using a drive assembly, enables automatic rotation of the handle cover without requiring a user to apply force, resulting in a high degree of automation.

[0011] Furthermore, the handle cover is a strip-shaped plate, with its rotation axis parallel to its long sides and offset from a midline parallel to its long sides. This arrangement allows the upper portion of the handle cover to rotate toward the finger-receiving space at a large rotation angle, exposing as much of the finger-receiving space as possible and providing ample space for the user's hand to be inserted.

[0012] Furthermore, the handle device further includes a heat source sensor electrically connected to the drive assembly. The heat source sensor is configured to cause the drive assembly to drive the handle cover to the open state when a user's hand approaches the handle cover, and to cause the drive assembly to drive the handle cover to the closed state when the user's hand moves away from the handle cover. This process of automatically opening and closing the handle cover using the heat source sensor is highly intelligent and can enhance the user experience.

[0013] Furthermore, the drive assembly includes a drive motor, a driving gear, and a driven gear, wherein the drive motor is mounted on the housing, the driving gear is fixedly mounted on the motor shaft of the drive motor, and the driven gear is coaxially fixedly arranged with the pin at one end of the handle cover and meshes with the driving gear. This arrangement of the drive assembly not only has a simple structure but also provides stable and reliable transmission, ensuring smooth opening and closing of the handle cover.

[0014] Furthermore, sleeves are fixedly mounted on both ends of the housing along the rotation axis of the handle cover. Pins at both ends of the handle cover are correspondingly inserted through the sleeves at both ends of the housing, and the pins rotate in engagement with the corresponding sleeves. This arrangement can reduce wear on the housing, reduce noise during rotation, and ensure smooth rotation.

[0015] Furthermore, the opening forms a mounting port for the handle cover, and the bottom cover seals the mounting port. A stop rib is provided at the edge of the opening, extending toward the finger receiving space. The outer edge of the handle cover is provided with a stepped surface for engaging with the stop rib. In the closed state, the stepped surface engages with the stop rib to prevent the handle cover from slipping out of the finger receiving space through the opening. The handle cover is provided with an operating hole, which is opposite to the connection hole provided in the bottom cover. This arrangement of the handle device ensures the overall assembly reliability of the handle device while also achieving effective connection with the housing.

[0016] Furthermore, the reset assembly includes a coil spring, one end of which abuts the handle cover, and the other end of which abuts the bottom cover. This arrangement of the reset assembly is not only simple in structure and low in cost, but also can reliably reset the handle cover.

[0017] Furthermore, the handle cover is provided with an annular rib on the side facing the finger receiving space, with the central region of the annular rib forming a receiving groove for the coil spring. This arrangement not only enhances the structural strength of the handle cover and extends its service life, but also securely accommodates the coil spring and prevents it from shifting.

[0018] Furthermore, the coil springs are multiple and spaced apart in a direction parallel to the rotation axis of the handle cover. This arrangement not only provides a reliable elastic restoring force for the handle cover, allowing it to quickly return to a closed state, but also increases the area of ​​action of the reset assembly on the handle cover, preventing the handle cover from partially sinking toward the finger receiving space.

[0019] Furthermore, the handle cover further includes a cap, which is mounted on the operation hole and blocks the operation hole. The provision of the cap can prevent the finger accommodation space from being exposed through the operation hole.

[0020] The second object of the present invention is to provide a mobile air conditioner to solve the technical problem that the handles of existing mobile air conditioners are prone to collecting dust and dirt.

[0021] The mobile air conditioner provided by the present invention comprises a housing, an air duct assembly arranged inside the housing, and the above-mentioned handle device, wherein the bottom cover of the handle device is fixedly connected to the air duct assembly.

[0022] By providing the above-mentioned handle device in the mobile air conditioner, the mobile air conditioner accordingly has all the advantages of the above-mentioned handle device, which will not be described in detail here.

[0023] In addition, by fixedly connecting the bottom cover of the handle device to the air duct assembly inside the shell, when transporting the mobile air conditioner, the carrying force acting on the handle device can be shared by the air duct assembly, and the air duct assembly is used to bear the weight, thereby reducing the force acting on the shell, and effectively preventing the shell from being damaged or broken due to the excessive weight of the mobile air conditioner.

[0047] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is given in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0048] Example 1

[0049] Figure 1 This is a schematic diagram of the structure of the handle device 010 provided in this embodiment being installed on the housing 020. Figure 1 As shown, this embodiment provides a handle device 010 , which is arranged on a housing 020 of a mobile air conditioner, wherein the housing 020 is provided with a finger receiving space 021 and an opening 024 communicating with the finger receiving space 021 .

[0050] Figure 2 This is a front view of the handle device 010 provided in this embodiment when it is installed on the housing 020 and the handle cover 100 is in a closed state. Figure 3 for Figure 2 In the AA section view, Figure 4 for Figure 2 In the BB section view, Figure 5 This is a front view of the handle device 010 provided in this embodiment when it is installed on the housing 020 and the handle cover 100 is in the open state. Figure 6 for Figure 5 In the CC section view, Figure 7 for Figure 5 DD section view in. Figures 2 to 7As shown, the handle device 010 includes a handle cover 100 rotatably arranged in the finger receiving space 021, a positioning retaining rib 200 fixedly arranged in the finger receiving space 021, and a reset assembly. The handle cover 100 has an open state (refer to FIG. 1 ) in which the finger receiving space 021 is exposed. Figures 5 to 7 ) and the closed state of the closed opening 024 (refer to Figures 2 to 4 ), in the closed state, the handle cover 100 is coplanar with the outer surface of the shell 020; the positioning rib 200 is used to rotate the handle cover 100 around the set direction to the open state; the reset assembly is used to restore the handle cover 100 to the closed state.

[0051] By providing a handle device 010 primarily consisting of a handle cover 100, a positioning rib 200, and a reset assembly, when the mobile air conditioner is not being transported, the handle cover 100 is in a closed state, sealing the opening 024. At this point, the handle cover 100 is coplanar with the outer surface of the housing 020. When the mobile air conditioner needs to be transported, the handle cover 100 can be rotated to expose the finger receiving space 021, forming a transport force point at the finger receiving space 021, allowing the user's hand to enter the finger receiving space 021 to transport the mobile air conditioner. The rotation of the handle cover 100 can be automatically achieved by the drive assembly 400, or manually achieved by the user's hand pressing. After the mobile air conditioner is transported, the handle cover 100 returns to the closed state under the action of the reset assembly.

[0052] The setting of the above-mentioned handle device 010 allows the concave finger-accommodating space 021 to be blocked by the handle cover 100 when the mobile air conditioner does not need to be carried. At this time, the handle cover 100 is coplanar with the outer shell 020, and there is no concave area on the outer surface of the mobile air conditioner. Not only will dust and dirt not accumulate, it solves the technical problem that the handles of existing mobile air conditioners are prone to dust and dirt, and also ensures the overall aesthetics of the mobile air conditioner.

[0053] In addition, by providing a positioning rib 200 in the finger accommodating space 021, the handle cover 100 can only be rotated in a set direction when the handle cover 100 needs to be switched from a closed state to an open state, thereby eliminating the tedious steps of requiring the user to try to rotate the handle cover 100 in multiple directions, saving the opening time of the handle cover 100, and thus improving the opening efficiency of the handle cover 100.

[0054] Please continue to refer to Figure 3 、 Figure 4 、 Figure 6 and Figure 7In this embodiment, the portion of the finger accommodating space 021 opposite to the opening 024 is set as an opening, and the handle device 010 can further include a bottom cover 300, wherein the bottom cover 300 is detachably fixedly connected to the shell 020.

[0055] By setting the finger accommodating space 021 as a through structure along the thickness direction of the shell 020 and providing a bottom cover 300 that is detachably fixedly connected to the shell 020, on the one hand, it is convenient for the processing and forming of the shell 020, and on the other hand, it can also realize the detachable installation of the handle device 010 on the shell 020, which is convenient for the disassembly and maintenance of the handle device 010.

[0056] Please continue to refer to Figure 1 In this embodiment, the housing 020 is provided with threaded posts 023, and the bottom cover 300 is screwed into the threaded posts 023 by means of connecting screws, thereby achieving a detachable fixed connection between the bottom cover 300 and the housing 020. There are two threaded posts 023, which are arranged at a set of diagonal positions on the bottom cover 300. This arrangement not only ensures the reliability of the connection between the bottom cover 300 and the housing 020, but also prevents the bottom cover 300 from partially tilting.

[0057] In this embodiment, when the bottom cover 300 needs to be disassembled, it can be done inside the housing 020 .

[0058] Please continue to refer to Figure 3 、 Figure 4 、 Figure 6 and Figure 7 In this embodiment, a connection hole 311 can be opened in the bottom cover 300, wherein the connection hole 311 is used to be fixedly connected to the air duct component of the mobile air conditioner.

[0059] When assembling the handle 010, the connecting screws can be passed through the connecting holes 311 provided in the bottom cover 300 and screwed into the air duct assembly within the housing 020. This arrangement allows the air duct assembly to share the carrying force acting on the handle 010 when transporting the mobile air conditioner. By using the air duct assembly to bear the weight, the force acting on the housing 020 is reduced, effectively preventing damage or breakage of the housing 020 caused by the excessive weight of the mobile air conditioner.

[0060] Please continue to refer to Figure 3 、 Figure 4 、 Figure 6 and Figure 7 In this embodiment, the bottom cover 300 is provided with a support platform 310, wherein the connection hole 311 is opened on the support platform 310. This arrangement can increase the structural strength of the central opening area of ​​the bottom cover 300.

[0061] Please continue to refer to Figure 2 、 Figure 5 and Figure 6 In this embodiment, both ends of the handle cover 100 along its rotation axis 120 are rotatably mounted on the housing 020 via pins 110. The handle device 010 may further include a drive assembly 400, wherein the drive assembly 400 is transmission-connected to the handle cover 100 for driving the handle cover 100 to switch between an open state and a closed state.

[0062] When the handle cover 100 needs to be opened to transport the mobile air conditioner, the drive assembly 400 can be activated to drive the handle cover 100 from a closed state to an open state, exposing the finger receiving space 021 so that the user can insert the finger receiving space 021, thereby completing the transport operation of the mobile air conditioner. After the transport operation of the mobile air conditioner is completed, the drive assembly 400 can be used again to rotate the handle cover 100 in a direction opposite to the above direction, switching the handle cover 100 from the open state to the closed state, sealing the opening 024 connected to the finger receiving space 021, and preventing the formation of a concave area on the outer surface of the mobile air conditioner.

[0063] This arrangement of using the drive assembly 400 to open and close the handle cover 100 can realize automatic rotation of the handle cover 100. During the rotation of the handle cover 100, there is no need for the user to provide force, and the degree of automation is high.

[0064] It should be noted that, in this embodiment, the process of the driving assembly 400 driving the handle cover 100 to close can be regarded as the process of the resetting assembly resetting the handle cover 100 .

[0065] In this embodiment, the setting of the positioning rib 200 can also be used to limit the handle cover 100 during the process of the drive assembly 400 closing the handle cover 100, so that the handle cover 100 can accurately move to the closed state to be coplanar with the outer surface of the shell 020.

[0066] Please continue to refer to Figure 2 and Figure 5 In this embodiment, the handle cover 100 has a strip-shaped plate structure. Specifically, the rotation axis 120 of the handle cover 100 is parallel to its long side, and the rotation axis 120 of the handle cover 100 deviates from the center line parallel to its long side.

[0067] By setting the rotation axis 120 of the handle cover 100 to be parallel to its long side, after the handle cover 100 is rotated open, the finger receiving space 021 has a sufficient lateral size to facilitate the user to insert the hand. At the same time, by making the rotation axis 120 of the handle cover 100 deviate from the midline parallel to its long side, Figure 2From the perspective shown, the rotation axis 120 of the handle cover 100 is arranged downward, so that when the upper part of the handle cover 100 is rotated toward the finger accommodating space 021, it has a larger rotation angle, so that the finger accommodating space 021 can be exposed as much as possible, providing sufficient space margin for the user's hand to be inserted.

[0068] In this embodiment, Figure 2 The perspective shown is when the mobile air conditioner is in an upright state and the handle device 010 is installed on the housing 020 of the mobile air conditioner.

[0069] In this embodiment, the handle device 010 may further include a heat source sensor, wherein the heat source sensor is electrically connected to the drive assembly 400. Specifically, the heat source sensor is configured to cause the drive assembly 400 to drive the handle cover 100 to an open state when the user's hand approaches the handle cover 100, and to cause the drive assembly 400 to drive the handle cover 100 to a closed state when the user's hand moves away from the handle cover 100.

[0070] When the handle device 010 is in use, when the user's hand approaches the handle cover 100, the heat source sensor will sense a heat signal and send the heat signal to the controller of the mobile air conditioner, and the controller will control the drive component 400 to work, so that the handle cover 100 is switched from a closed state to an open state; when the user completes moving the mobile air conditioner, that is, when the user's hand is away from the handle cover 100, the heat source sensor will no longer detect the heat signal, and the controller will control the drive component 400 to work again, so that the handle cover 100 is switched from an open state to a closed state.

[0071] This process of automatically opening and closing the handle cover 100 by utilizing the induction of a heat source sensor is highly intelligent and can enhance the user experience.

[0072] In this embodiment, the heat source sensor can be installed in the housing 020. This arrangement prevents the heat source sensor from moving during the opening and closing of the handle cover 100. This reduces the load on the handle cover 100, making the opening and closing of the handle cover 100 smoother. Furthermore, it prevents the heat source sensor from shifting due to repeated opening and closing of the handle cover 100, which could lead to reduced detection accuracy.

[0073] Please continue to refer to Figure 3 and Figure 6In this embodiment, the driving assembly 400 may include a driving motor 410, a driving gear 420 and a driven gear 430. Specifically, the driving motor 410 is installed on the housing 020, the driving gear 420 is fixedly sleeved on the motor shaft of the driving motor 410, and the driven gear 430 is coaxially fixedly arranged with the pin shaft 110 at one end of the handle cover 100 and meshes with the driving gear 420.

[0074] When the handle cover 100 needs to be switched to the open state, the drive motor 410 can be rotated forward to drive the driving gear 420 to rotate, and the meshing action of the driving gear 420 and the driven gear 430 is used to transmit the rotational force to the driven gear 430, thereby opening the handle cover 100; when the handle cover 100 needs to be switched to the closed state, the drive motor 410 can be reversed to drive the driving gear 420 to rotate in the opposite direction, and the meshing action of the driving gear 420 and the driven gear 430 is similarly used to transmit the rotational force to the driven gear 430, thereby rotating the handle cover 100 in the opposite direction to close.

[0075] This arrangement of the drive assembly 400 not only has a simple structure, but also has a stable and reliable transmission, thereby ensuring the smooth opening and closing of the handle cover 100 .

[0076] In this embodiment, the driven gear 430 and the pin shaft 110 at one end of the handle cover 100 can be configured as an integrated structure, that is, the pin shaft 110 at the end of the handle cover 100 is configured in the form of a gear shaft.

[0077] In this embodiment, the handle cover 100 includes a plate body and ear plates arranged on both sides of the plate body. The ear plates serve as the installation base of the pin shaft 110 on the one hand, and on the other hand, can also play a structural reinforcement role for the plate body to ensure the structural strength of the handle cover 100.

[0078] Please continue to refer to Figure 6 In this embodiment, shaft sleeves 440 are provided at both ends of the outer shell 020 along the rotation axis 120 of the handle cover 100. Specifically, the pins 110 at both ends of the handle cover 100 are correspondingly passed through the shaft sleeves 440 at both ends of the outer shell 020, and the pins 110 are rotatably matched with the corresponding shaft sleeves 440.

[0079] By providing a shaft sleeve 440 for rotatably cooperating with the pin shaft 110 in the housing 020, on the one hand, the wear on the housing 020 can be reduced, and on the other hand, the noise during the rotation process can be reduced and the smoothness of the rotation process can be ensured.

[0080] In this embodiment, the drive motor 410 can be mounted outside the finger receiving space 021, and the driving gear 420 can be positioned within the finger receiving space 021. The motor shaft of the drive motor 410 extends into the finger receiving space 021 and is connected to the driving gear 420. This arrangement can reduce the number of components disposed within the finger receiving space 021. This prevents the handle cover 100 from colliding with components within the finger receiving space 021 after rotation, and also prevents components from being exposed after the handle cover 100 is opened.

[0081] Please continue to refer to Figure 6 In this embodiment, the plate body of the handle cover 100 is provided with an annular rib 140. By providing the annular rib 140, the structural strength of the handle cover 100 can be further increased.

[0082] Figure 8 This is a schematic diagram of the structure of the mobile air conditioner provided in this embodiment. Figure 9 This is the front view of the mobile air conditioner provided in this embodiment (the handle device 010 is installed on the side of the mobile air conditioner). Figure 8 and Figure 9 As shown, this embodiment also provides a mobile air conditioner, including a shell 020, an air duct assembly (not shown in the figure) arranged inside the shell 020, and the handle device 010 in the first embodiment, wherein the bottom cover 300 of the handle device 010 is fixedly connected to the air duct assembly.

[0083] By providing the above-mentioned handle device 010 in the mobile air conditioner, the mobile air conditioner accordingly has all the advantages of the above-mentioned handle device 010, which will not be described in detail here.

[0084] The handle devices 010 are provided on both sides of the mobile air conditioner, and this arrangement facilitates the user to apply force on both sides of the mobile air conditioner.

[0086] This embodiment provides another handle device 010. This handle device 010 differs from the handle device 010 provided in the first embodiment primarily in that it is mechanical, requiring the user to apply force to the handle cover 100 to open it. The following text details the specific structure and operating principle of this handle device 010. Structures identical to those of the handle device 010 in the first embodiment are not described in detail; only the differences are discussed.

Figures 10 to 15 As shown, the handle device 010 provided in this embodiment has an opening provided at a position opposite to the finger receiving space 021 and the opening 024, forming an installation opening for the handle cover 100, wherein the bottom cover 300 closes the installation opening; a stop rib 022 is provided at the edge of the opening 024, and the stop rib 022 extends toward the finger receiving space 021, and a step surface 130 is provided on the outer edge of the handle cover 100 for cooperating with the stop rib 022; in the closed state, the step surface 130 cooperates with the stop rib 022 to prevent the handle cover 100 from escaping from the finger receiving space 021 through the opening 024; the handle cover 100 is provided with an operating hole 150, and the operating hole 150 is opposite to the connecting hole 311 provided in the bottom cover 300.

[0088] When assembling and connecting the handle device 010 and the shell 020, the handle cover 100 can be first placed into the finger receiving space 021 from the opening of the finger receiving space 021, and the stop rib 022 can be used to cooperate with the step surface 130 of the handle cover 100 to limit the position of the handle cover 100; after the other components of the handle device 010 are installed, the bottom cover 300 is placed into the opening position from the inside of the shell 020, and then, the connecting screws are used to pass through the operation hole 150 opened in the handle cover 100 and the connecting hole 311 opened in the bottom cover 300 in sequence, and then screwed to the air duct assembly, thereby completing the assembly operation of the handle device 010.

[0089] This arrangement of the handle device 010 ensures the overall assembly reliability of the handle device 010 while also enabling effective connection between the handle device 010 and the housing 020 .

[0090] Please continue to refer to Figure 11 、 Figure 12 、 Figure 14 and Figure 15 In this embodiment, the reset assembly may include a coil spring 500 . Specifically, one end of the coil spring 500 abuts against the handle cover 100 , and the other end of the coil spring 500 abuts against the bottom cover 300 .

[0091] When it is necessary to switch the handle cover 100 from a closed state to an open state, pressing force can be applied to the handle cover 100. Due to the presence of the positioning rib 200, the handle cover 100 can only be rotated in one direction, thereby opening the handle cover 100. During this process, the coil spring 500 is compressed; after completing the carrying operation of the mobile air conditioner, when the user's hand withdraws from the finger accommodating space 021, the handle cover 100 will return to the closed state under the action of the elastic restoring force of the coil spring 500.

[0092] This arrangement of the reset component is not only simple in structure and low in cost, but also can achieve reliable reset of the handle cover 100 .

[0093] Please continue to refer to Figure 11 and Figure 14 In this embodiment, an annular rib 140 is provided on one side of the handle cover 100 facing the finger receiving space 021 , wherein the middle area of ​​the annular rib 140 forms a receiving groove for the coil spring 500 .

[0094] The provision of the annular rib 140 can, on the one hand, enhance the structural strength of the handle cover 100 and extend the service life of the handle cover 100 , and on the other hand, can also accommodate the coil spring 500 and prevent the coil spring 500 from shifting.

[0095] In this embodiment, there are two coil springs 500 , and the two coil springs 500 are arranged at intervals along a direction parallel to the rotation axis 120 of the handle cover 100 .

[0096] Through this arrangement, on the one hand, a reliable elastic restoring force can be provided for the handle cover 100, so that the handle cover 100 can be quickly restored to the closed state. On the other hand, the effective area of ​​the reset component on the handle cover 100 can be increased to prevent the handle cover 100 from partially sinking toward the finger accommodating space 021.

[0097] In other embodiments, the number of the coil springs 500 may be three or four, as long as the handle cover 100 can be reliably reset by such an arrangement of the coil springs 500 .

[0098] It should be noted that when there are multiple coil springs 500 , the number of annular ribs 140 provided on the handle cover 100 is also correspondingly multiple. In this case, the multiple coil springs 500 are respectively installed at the positions of the multiple annular ribs 140 .

[0099] Please continue to refer to Figures 11 to 15 In this embodiment, the handle cover 100 may further include a cover cap 160 . Specifically, the cover cap 160 is installed on the operation hole 150 and blocks the operation hole 150 .

[0100] After the handle assembly 010 is assembled and connected to the housing 020, the operating hole 150 can be sealed with the cap 160. The cap 160 prevents the finger receiving space 021 from being exposed through the operating hole 150. This prevents dust and impurities from entering the finger receiving space 021 through the operating hole 150, while also ensuring the surface integrity of the handle cover 100.

[0101] It should be noted that in this embodiment, the handle cover 100 used in the handle device 010 can be used in conjunction with the handle cover 100 used in the handle device 010 of the first embodiment. That is, the handle cover 100 used in the second embodiment can also be used in the handle device 010 provided in the first embodiment. This arrangement allows the same handle cover 100 to be used when manufacturing different handle devices 010, resulting in a high degree of component standardization.
