The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0037] See also Figures 1 to 5 An embodiment of the present application provides a handheld cleaning device 100 , including a body module 10 and a handle module 20 .

[0038] The body module 10 includes a body 11 and a button structure 12 disposed on the body 11. The body 11 is provided with an installation cavity 110. The cavity wall of the installation cavity 110 is provided with a card slot 111. The button structure 12 is located outside the cavity wall. The handle module 20 includes a handle 21 and an elastic lock structure 22 disposed in the handle 21. The handle 21 is partially inserted into the installation cavity 110. The elastic lock structure 22 includes a fastening member 220 and a first elastic member 221. The fastening member 220 corresponds to the position of the card slot 111. The first elastic member 221 is provided with a first elastic member 222. An elastic member 221 is provided at one end of the buckle 220 away from the slot 111; when the button structure 12 is in an unpressed state, the buckle 220 is engaged with the slot 111 under the action of the first elastic member 221 to limit the relative movement of the handle 21 and the body 11; when the button structure 12 is in a pressed state, the button structure 12 drives the buckle 220 to move in a direction away from the slot 111, so that the buckle 220 is disengaged from the slot 111, and the handle 21 can move relative to the body 11.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, the body module 10 includes a body 11 and a button structure 12, wherein the button structure 12 is mounted on the body 11 in a manner that it can slide up and down, wherein the button structure 12 is at least partially exposed to the outside to facilitate being pressed by a user.

[0040] The handle module 20 includes a handle 21 and an elastic locking structure 22. The handle 21 may be a roughly rod-shaped structure, and the handle 21 may be held by a user for the convenience of cleaning. The elastic locking structure 22 is mounted on the handle 21 and is close to the bottom end of the handle 21. The elastic locking structure 22 includes a fastening member 220 and a first elastic member 221. The first elastic member 221 may be a spring. The first elastic member 221 may be disposed inside the handle 21. One end of the fastening member 220 abuts against the first elastic member 221, and in a natural state (when the fastening member 220 is not subjected to an external force), the other end of the fastening member 220 at least partially protrudes from the outer side of the handle 21. When the fastening member 220 is subjected to an external force, the fastening member 220 may compress the first elastic member 221 and move toward the inner side of the handle 21.

[0041] like Figure 4 and Figure 5 As shown, Figure 4 is a structural schematic diagram of a key structure in an unpressed state. Figure 5 It is a structural schematic diagram of the key structure when it is in a pressed state.

[0042] When the handle 21 needs to be installed on the body 11, the bottom end of the handle 21 is aligned with the installation cavity 110 on the body 11, and the handle 21 is pushed in the direction of the body 11. During this process, the buckle 220 first contacts the inner wall of the installation cavity 110. Under the action of the inner wall of the installation cavity 110, the buckle 220 moves toward the direction of the first elastic member 221 and compresses the first elastic member 221. As the handle 21 continues to be pushed, the buckle 220 gradually moves toward the direction of the card slot 111 on the cavity wall of the installation cavity 110 until the positions of the buckle 220 and the card slot 111 correspond. Under the action of the restoring force of the first elastic member 221, the buckle 220 moves toward the card slot 111, so that the buckle 220 is engaged with the card slot 111 (see Figure 4 ), thereby achieving the locking of the handle 21 and the body 11.

[0043] When the handle 21 needs to be removed from the body 11, the user only needs to press the button structure 12, and the button structure 12 drives the fastening member 220 to move away from the slot 111, so that the fastening member 220 is separated from the slot 111, thereby unlocking the handle 21 and the body 11 (see FIG. Figure 5 ), at this time, the user can pull the handle 21 out of the installation cavity 110, and the removal process of the handle 21 is convenient and fast, saving time and effort.

[0044] It can be seen that in this embodiment, the handle 21 can be quickly installed through the elastic locking structure 22, and the handle 21 can be quickly removed through the cooperation between the button structure 12 and the elastic locking structure 22, thereby achieving the purpose of quick disassembly and assembly of the handle 21. In addition, by separately arranging the elastic locking structure 22 on the handle 21 to achieve quick installation of the handle 21, the handle 21 can be prevented from interfering with the button structure 12 during the installation process, thereby improving the use stability of the button structure 12 and avoiding damage to the button structure 12.

[0045] In some embodiments, the key structure 12 includes a release button 120 and a slider 121, which can be slidably installed on the body 11 respectively, the release button 120 can slide along a first direction relative to the body 11, and the slider 121 can slide along a second direction relative to the body 11, wherein the first direction and the second direction are set at an angle; when the release button 120 is in a pressed state, the release button 120 slides along the first direction and cooperates with the slider 121 to drive the slider 121 to slide along the second direction, so that the slider 121 pushes the fastener 220, and the fastener 220 moves in a direction away from the slot 111 and disengages from the slot 111.

[0046] like Figure 4 and Figure 5 As shown in the figure, the Y direction represents the first direction, and the X direction represents the second direction. Optionally, the first direction can be the length direction of the handle 21 (corresponding to the vertical direction), and the second direction can be the radial direction of the handle 21 (corresponding to the horizontal direction), and the first direction and the second direction are perpendicular to each other.

[0047] The release button 120 and the slider 121 are respectively slidably matched with the body 11, and the release button 120 can slide in a first direction relative to the body 11, and the slider 121 can slide in a second direction relative to the body 11. It can be understood that when the slider 121 slides in the second direction relative to the body 11, the slider 121 can slide in a direction toward the fastening member 220 or slide in a direction away from the fastening member 220.

[0048] When the release button 120 is in a non-pressed state, the slider 121 may abut against or separate from the buckling member 220 to avoid mutual interference between the slider 121 and the buckling member 220 .

[0049] When the handle 21 needs to be removed from the body 11, the user presses the release button 120, and the release button 120 moves in a first direction relative to the body 11. The release button 120 cooperates with the slider 121 and converts the movement of the release button 120 in the first direction into the movement of the slider 121 in a second direction, and then the slider 121 slides in the second direction relative to the body 11, that is, the slider 121 slides in the direction of the fastening member 220 and pushes the fastening member 220, so that the fastening member 220 moves in a direction away from the slot 111 and disengages from the slot 111. In this way, the handle 21 is unlocked from the body 11, and the user can pull out the handle 21.

[0050] like Figure 3As shown, in some embodiments, the button structure 12 also includes a second elastic member 122, which is disposed at the bottom end of the release button 120, and the two ends of the second elastic member 122 are respectively against the bottom end of the release button 120 and the body 11; when the release button 120 is in an unpressed state, the release button 120 can be restored to its initial position under the action of the second elastic member 122.

[0051] Specifically, the second elastic member 122 may be a spring, and the initial position is the position of the release button 120 when no external force is applied thereto.

[0052] When the release button 120 is pressed by the user, the release button 120 overcomes the elastic force of the second elastic member 122 and moves in the first direction, so that the release button 120 cooperates with the slider 121, pushing the fastening member 220 to move in a direction away from the card slot 111 and disengage from the card slot 111, thereby pulling the handle 21 out of the body 11. When the user releases the release button 120, the release button 120 returns to its initial position under the action of the restoring force of the second elastic member 122.

[0053] See also Figure 6 In some embodiments, the release button 120 has a first inclined surface 1200, and the end of the slider 121 facing away from the fastening member 220 has a second inclined surface 1210. When the release button 120 is in a pressed state, the first inclined surface 1200 and the second inclined surface 1210 slide together to drive the slider 121 to slide toward the fastening member 220.

[0054] like Figure 4 , Figure 5 and Figure 6 As shown, the release button 120 and the slider 121 respectively have a first inclined surface 1200 and a second inclined surface 1210 that cooperate with each other. The first inclined surface 1200 and the second inclined surface 1210 have the same inclination angle. Optionally, the first inclined surface 1200 and the second inclined surface 1210 are respectively inclined at an angle of 45 degrees relative to the horizontal direction to ensure that the movement of the release button along the first direction can be smoothly and evenly converted into the movement of the slider 121 along the second direction.

[0055] When the release button 120 is pressed, the release button 120 slides along the first direction, the first inclined surface 1200 slides relative to the second inclined surface 1210, pushing the slider 121 to slide along the second direction, the slider 121 slides toward the direction of the fastening member 220 and then pushes the fastening member 220, the fastening member 220 moves in the direction away from the card slot 111 so that the fastening member 220 is disengaged from the card slot 111.

[0056] In this embodiment, the movement of the release button 120 along the first direction is converted into the movement of the slider 121 along the second direction by the first inclined surface 1200 and the second inclined surface 1210 that cooperate with each other. It is understandable that in other embodiments, the movement of the release button 120 along the first direction can also be converted into the movement of the slider 121 along the second direction by other methods. For example, in one implementation, a cam mechanism can also be provided between the release button 120 and the slider 121. When the release button 120 is pressed, it will push the cam to rotate. The specific profile design of the cam makes it possible to push the slider 121 to move in the horizontal direction when it rotates.

[0057] In some embodiments, the button structure 12 further includes a guide member 123 , which is installed on the body 11 . The guide member 123 defines a guide groove 1230 , and the slider 121 is slidably installed in the guide groove 1230 .

[0058] The guide member 123 is located on the side of the release button 120 facing the handle 21, and the guide member 123 can be fixedly installed on the body 11 by means of screws, buckles, etc. The guide member 123 is provided with a guide groove 1230 for guiding and cooperating with the slider 121. Specifically, the slider 121 is slidably installed in the guide groove 1230 at one end facing the buckle 220. The guiding cooperation between the guide groove 1230 and the slider 121 can ensure that the slider 121 slides smoothly along the second direction.

[0059] In some other embodiments, a guide groove 1230 that cooperates with the guide of the slider 121 may be directly opened on the body 11 to enable the slider 121 to slide along the second direction.

[0060] In some embodiments, the key structure 12 further includes a third elastic member 124 (see Figure 6 ), a mounting hole 1211 is provided on the slider 121, a mounting post 1231 is fixedly connected to the side of the guide member 123 facing the slider 121, the mounting post 1231 is slidably installed in the mounting hole 1211, the third elastic member 124 is sleeved on the mounting post 1231, and the two ends of the third elastic member 124 are respectively against the guide member 123 and the slider 121; when the release button 120 is in an unpressed state, the slider 121 makes the second inclined surface 1210 and the first inclined surface 1200 against each other under the action of the third elastic member 124.

[0061] like Figure 6 As shown, a mounting post 1231 is connected to one side of the guide member 123 facing the second sliding portion 1213, one end of the mounting post 1231 is fixedly connected to the guide member 123, and the other end of the mounting post 1231 is slidably mounted in the mounting hole 1211. Optionally, the mounting post 1231 and the guide member 123 are an integrally formed structure to ensure the structural reliability.

[0062] The third elastic member 124 may be a spring. The third elastic member 124 is disposed between the guide member 123 and the slider 121 . The slider 121 may be reset under the action of the third elastic member 124 .

[0063] Specifically, when the release button 120 is pressed by the user, the release button 120 moves vertically downward and compresses the second elastic member 122 , and at the same time, the release button 120 pushes the slider 121 to move horizontally to the left, so that the third elastic member 124 is compressed.

[0064] When the release button 120 is released, the release button 120 moves in the vertical upward direction and returns to its initial position under the action of the second elastic member 122. At the same time, the slider 121 slides in the direction away from the fastening member 220 under the action of the third elastic member 124 until the second inclined surface 1210 on the slider 121 abuts against the first inclined surface 1200 on the release button 120. The first inclined surface 1200 limits the further sliding of the slider 121, thereby completing the resetting of the slider 121.

[0065] like Figure 6 As shown, in some embodiments, the slider 121 includes a first sliding portion 1212 and a second sliding portion 1213 that are fixedly connected, the first sliding portion 1212 is slidably mounted in the guide groove 1230, and the second inclined surface 1210 is provided on the first sliding portion 1212, the second sliding portion 1213 is provided on one side of the second inclined surface 1210, and the mounting hole 1211 is opened in the second sliding portion 1213. The third elastic member 124 is located between the second sliding portion 1213 and the guide member 123, and the two ends of the third elastic member 124 are respectively against the second sliding portion 1213 and the guide member 123.

[0066] In some embodiments, the button structure 12 also includes a screw, and a threaded hole 1232 is also provided at the end of the mounting column 1231. The rod of the screw is threadedly fixedly engaged with the threaded hole 1232, and under the action of the third elastic member 124, the head of the screw can be against the second sliding portion 1213, so that the sliding stroke of the slider 121 can be limited by the screw, and the position of the slider 121 after resetting can be determined.

[0067] It is understandable that when the reset position of the slider 121 is limited by setting a screw, after the slider 121 is in the reset position, the second inclined surface 1210 may not contact the first inclined surface 1200, thereby reducing the interference between the release button 120 and the slider 121 and improving the stability and durability of the release button 120.

[0068] In addition, it should be pointed out that in some embodiments, the second elastic member 122 may not be provided. In this case, the slider 121 and the release button 120 can be reset by the third elastic member 124. Specifically, when the release button 120 is released, the slider 121 moves in a direction away from the fastening member 220 under the action of the third elastic member 124 to complete the reset of the slider 121. At the same time, the slider 121 pushes the release button 120 to move vertically upward to complete the reset of the release button 120.

[0069] See also Figure 7 In some embodiments, when the key structure 12 is in an unpressed state, the top surface 1201 of the key structure 12 is flush with the top surface 112 of the body 11 .

[0070] Specifically, when the release button 120 is not pressed, the top surface 1201 of the release button 120 is flush with the top surface 112 of the body 11. In this way, on the one hand, the user can be prevented from accidentally touching the release button 120, thereby preventing the release of the handle 21 from being triggered by an accidental touch of the release button 120, thereby improving the safety of use. On the other hand, the top surface 1201 of the release button 120 is flush with the top surface 112 of the body 11, which can maintain the flatness of the top of the body module 10.

[0071] Please refer to Figure 4 and Figure 5 In some embodiments, the handle 21 includes a connecting tube 210, which is partially inserted into the installation cavity 110. A connecting groove 2100 is provided on the tube wall of the connecting tube 210, and the connecting groove 2100 corresponds to the position of the buckle 220. The elastic locking structure 22 also includes a fixed bracket 222, which is arranged in the connecting tube 210. The fixed bracket 222 is provided with an installation groove 2220. The buckle 220 is installed in the installation groove 2220 and can slide relative to the fixed bracket 222. The first elastic member 221 is arranged between the buckle 220 and the fixed bracket 222, and the two ends of the first elastic member 221 are respectively against the fixed bracket 222 and the buckle 220.

[0072] The handle 21 includes a connecting tube 210 and a grip portion 211 (see Figure 1 ), the bottom end of the connecting tube 210 is inserted into the mounting cavity 110, and the gripping portion 211 is connected to the top end of the connecting tube 210. The gripping portion 211 is roughly annular in structure for easy gripping by the user.

[0073] A connecting groove 2100 is opened on the tube wall of the connecting tube 210, and the fixing bracket 222 is fixedly installed in the connecting tube 210. Optionally, the fixing bracket 222 can be inserted into the connecting tube 210 through the bottom end of the connecting tube 210, and the fixing bracket 222 can be fixed by screws, clamping, etc.

[0074] A mounting groove 2220 is provided on the fixed bracket 222, and the first elastic member 221 and the buckle member 220 are respectively installed in the mounting groove 2220, wherein the buckle member 220 and the fixed bracket 222 are slidably matched, and the first elastic member 221 is arranged between the groove bottom of the mounting groove 2220 and the buckle member 220. When the bottom end of the connecting tube 210 is inserted into the mounting cavity 110, the positions of the mounting groove 2220 and the connecting groove 2100 can correspond to the position of the card slot 111. At this time, under the action of the first elastic member 221, the buckle member 220 can slide relative to the fixed bracket 222, so that the buckle member 220 slides toward the direction of the card slot 111 and is buckled with the card slot 111, thereby locking the handle 21 on the body 11.

[0075] In some embodiments, the snap-fitting member 220 includes a column 2200, a limiting ring 2201 and a snap-fitting portion 2202. The limiting ring 2201 is arranged around the outer periphery of the column 2200, and the snap-fitting portion 2202 is arranged at the end of the column 2200 away from the mounting slot 2220. When the button structure 12 is in an unpressed state, the snap-fitting portion 2202 is snap-fitted with the slot 111. A guide hole 2221 is provided at the bottom of the mounting slot 2220, and the end of the column 2200 away from the snap-fitting portion 2202 is slidably installed in the guide hole 2221. The first elastic member 221 is sleeved on the column 2200, and the two ends of the first elastic member 221 are respectively against the bottom of the mounting slot 2220 and the limiting ring 2201.

[0076] Optionally, the column 2200 , the limiting ring 2201 and the buckling portion 2202 are an integrally formed structure to ensure the structural strength of the buckling member 220 .

[0077] A guide hole 2221 is provided at the bottom of the mounting groove 2220, and the guide hole 2221 passes through the bottom of the mounting groove 2220. The column 2200 is in a roughly cylindrical structure and is adapted to the size of the guide hole 2221. One end of the column 2200 away from the snap-fit ​​portion 2202 is inserted into the guide hole 2221. The guiding sliding cooperation between the column 2200 and the guide hole 2221 ensures that the snap-fitting part 220 slides along the second direction (such as the horizontal direction).

[0078] The buckling portion 2202 is located at one end of the column 2200 facing the slot 111. Under the action of the first elastic member 221, the column 2200 can slide relative to the guide hole 2221, and the buckling member 220 slides toward the slot 111, so that the buckling portion 2202 is engaged with the slot 111.

[0079] In some embodiments, the elastic locking structure 22 also includes a fastener 223, and a connecting hole 2203 is opened on the end face of the column 2200. The rod of the fastener 223 is tightly fitted with the connecting hole 2203. When the button structure 12 is in an unpressed state, the head of the fastener 223 is against the outer bottom surface 2222 of the mounting groove 2220.

[0080] The fastener 223 can be a screw, a bolt, etc. The fastener 223 includes a head and a rod that are connected to each other. A connecting hole 2203 is provided on the end face of the column 2200. The rod of the fastener 223 is tightly matched with the connecting hole 2203 to realize the fixed connection between the fastener 220 and the fastener 223. The head of the fastener 223 can be abutted against the outer bottom surface 2222 of the mounting groove 2220 to limit the sliding stroke of the fastener 220 and determine the position of the fastener 220 after it is reset.

[0081] Specifically, when the handle 21 needs to be installed on the body 11, the bottom end of the handle 21 is aligned with the installation cavity 110 on the body 11, and the handle 21 is pushed in the direction of the body 11. During this process, the buckle portion 2202 first contacts the inner wall of the installation cavity 110, and under the action of the inner wall of the installation cavity 110, the buckle member 220 moves toward the direction of the first elastic member 221 and compresses the first elastic member 221. As the handle 21 continues to be pushed, the buckle member 220 will gradually move toward the installation cavity 110. The fastener 220 moves in the direction of the slot 111 on the wall of the cavity 110 until the snap-fitting portion 2202 corresponds to the position of the slot 111. The snap-fitting portion 220 moves toward the slot 111 under the action of the restoring force of the first elastic member 221, so that the snap-fitting portion 2202 and the slot 111 are assembled in place, thereby realizing the locking of the handle 21 and the body 11. At the same time, the head of the fastener 223 abuts against the outer bottom surface 2222 of the mounting slot 2220, limiting the continued movement of the snap-fitting portion 2202.

[0082] In some embodiments, a guide surface 2204 is provided at the bottom end of the snap-fit ​​portion 2202. During the process of inserting the handle 21 into the installation cavity 110, the guide surface 2204 first contacts the inner wall of the installation cavity 110 and cooperates with the inner wall of the installation cavity 110 to facilitate the insertion of the handle 21 into the installation cavity 110 and reduce the difficulty of installing the handle 21.
