Description

Technical Field

[0001] The present technical solution relates to the technical field of handheld vacuum cleaners, and in particular to a handheld vacuum cleaner. Background Art

[0002] A handheld vacuum cleaner is a new type of household appliance that can be held by hand for vacuuming. Its main feature is its small size, making it very convenient to carry and use. It is particularly suitable for cleaning smaller spaces, such as in cars, keyboards, and electrical appliances.

[0003] The shell of the existing handheld vacuum cleaner is mostly installed by splicing two half shells together and fixing the two half shells with screws. This shell installation and processing method has the following disadvantages:

[0004] 1. Mutually compatible screw holes need to be opened on both half shells, so more corresponding processes need to be added when producing the shells, resulting in reduced production time.

[0005] 2. When processing the half shell, it is necessary to manually screw the screws to fix it, which once again increases the production time. In addition, when the shell is opened for subsequent maintenance of the vacuum cleaner, the screws need to be removed and installed again, which is a cumbersome and time-consuming process.

[0006] 3. After multiple disassembly and installation of the screws, the screw holes and screws will be worn out, resulting in misalignment when the screws are installed again, which in turn causes the shell to loosen, affecting the use of the handheld vacuum cleaner. Summary of the invention

[0007] The purpose of the technical solution is to provide a handheld vacuum cleaner, which directly fixes the shell one and the shell two that are spliced ​​together by a pair of locking parts, thereby solving the problem that the process of connecting the shells by screws is cumbersome and time-consuming, and has a short service life.

[0008] The purpose of this technical solution is achieved in this way:

[0009] A handheld vacuum cleaner comprises: an outer shell having an installation chamber formed therein, and comprising a shell body 1 and a shell body 2, wherein the shell body 1 and the shell body 2 are spliced ​​together to form the outer shell; a dust suction device, which is arranged in the installation chamber and is used for dust suction; and a locking member 1, which is simultaneously and movably engaged with the shell body 1 and the shell body 2, and is used for fixing the shell body 1 and the shell body 2 together.

[0010] Preferably, a snap-in block 1 and a snap-in block 2 are respectively protruded on the outer side walls of the shell 1 and the shell 2. When the shell 1 and the shell 2 are spliced ​​together, the snap-in block 1 and the snap-in block 2 cooperate to form a snap-in portion 1; and a snap-in groove 1 adapted to the snap-in portion 1 is formed in the locking member 1.

[0011] Preferably, the clamping portion 1 cooperates with the outer shell to form a slide groove, and both ends of the locking member 1 are movably clamped in the slide groove.

[0012] Preferably, a positioning block is protrudingly formed on the side wall surface of the shell one, and a positioning groove adapted for the positioning block is concavely formed on the side wall surface of the shell two.

[0013] Preferably, a locking block is provided on the first shell, and a locking groove adapted to the locking block is provided on the second shell.

[0014] Preferably, a locking piece 2 is provided on the outer shell; a snap-in block 3 and a snap-in block 4 are respectively protruded on the outer side walls of the shell 1 and the shell 2, and when the shell 1 and the shell 2 are spliced, the snap-in block 3 and the snap-in block 4 cooperate to form a snap-in portion 2; a snap-in groove 2 adapted to the snap-in portion 2 is formed in the locking piece 2; the locking piece 2 is arranged in the space enclosed by the locking piece 1 and the outer shell.

[0015] Preferably, the first clamping portion is recessed to form a clearance opening, and the clearance opening is located at the front end of the second clamping portion, and the second locking member can enter from the clearance opening and be clamped on the second clamping portion.

[0016] Preferably, the two edges of the locking piece are folded outward to form an abutment portion, the inner wall of the locking piece has an abutment groove, and a stop block is arranged in the abutment groove; when the locking piece is installed on the outer shell, the abutment portion is movably placed in the abutment groove and movably abuts the stop block to fix the locking piece on the outer shell.

[0017] Preferably, the dust suction device comprises: a cover body, which is arranged at the front end of the outer shell; a cover cover, whose front end is hinged to the cover body by a spring, and whose rear end is movably connected to a flip button arranged on the shell; the spring makes the cover cover always have a tendency to open, and pressing the flip button can unlock the cover cover.

[0018] Preferably, the dust suction device comprises at least: a dust suction power part, which is arranged in the installation chamber; a closing part, which is arranged at the front end of the outer shell and is used to fix the dust suction power part in the installation chamber; and a cleaning HEPA part, which is arranged on the closing part through a mounting base; wherein the rear end of the cover shell body fixes the mounting base on the closing part.

[0019] Compared with the prior art, the technical solution has the following outstanding and beneficial technical effects:

[0020] 1. The locking member 1 designed in the technical solution can be directly connected to the shell 1 and the shell 2 at the same time to fix the shell 1 and the shell 2 together.

[0034] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0035] [Example 1]

[0036] like Figure 1 As shown, a handheld vacuum cleaner comprises: an outer shell 1, a dust suction device 5 and a locking piece 6, the dust suction device 5 is arranged in an installation chamber 2 formed inside the outer shell 1, and the locking piece 6 is movably arranged on the outer shell 1. The present application mainly improves the fixing method of the outer shell 1. A locking piece 6 is arranged on the outer shell 1, and the outer shell 1 is fixed by the locking piece 6, without the need to fix the outer shell 1 with screws.

[0037] Specifically, the outer shell 1 is composed of a shell 1 3 and a shell 2 4. The outer shell 1 is approximately a cylindrical structure with a hollow interior. The shell 1 3 and the shell 2 4 are approximately half a cylindrical structure respectively. The shell 1 3 and the shell 2 4 are spliced ​​together to form the outer shell 1. The front end of the outer shell 1 has an opening for the dust suction device 5 to suction dust. The locking piece 6 is detachably arranged at the connection between the shell 1 3 and the shell 2 4, and can be slidably installed along the length direction of the outer shell 1. When the outer shell 1 needs to be fixed, the locking piece 6 can be installed on the outer shell 1, and the length of the locking piece 6 placed on the outer shell 1 can be freely controlled.

[0038] Furthermore, the locking piece 6 can be used as a hand-held handle of the handheld vacuum cleaner. When the locking piece 6 is completely placed on the outer shell 1, the middle part of the outer shell 1 can be held. When the locking piece 6 is partially placed on the outer shell 1, the rear end of the locking piece 6 can be held to extend the handheld vacuum cleaner into a small space that needs to be cleaned for deep cleaning.

[0039] like Figure 2 As shown, the locking piece 6 is in a "U" shape, and its front and rear ends are slidably arranged on the left and right sides of the outer shell 1 respectively. Therefore, the locking piece 6 needs to be radially fixed on the outer shell 1 to ensure that the locking piece 6 will not fall off the outer shell 1.

[0040] Specifically, a clamping block 1 7 and a clamping block 2 8 are respectively protruded on the left and right outer walls of the shell 1 3 and the shell 2 4. The cross-section of the clamping block 1 7 and the clamping block 2 8 is set to be wide at the top and narrow at the bottom. Therefore, the clamping block 1 7 and the clamping block 2 8 can cooperate with the surface of the outer shell 1 to form a slide groove 11, so that when the locking piece 1 6 is set on the outer shell 1, it can be radially limited.

[0041] Furthermore, when the shell 1 3 and the shell 2 4 are spliced ​​together, the clamping block 1 7 and the clamping block 2 8 cooperate to form a clamping portion 1 9, and a clamping groove 10 adapted to the clamping portion 9 is formed in the locking member 6. The locking member 6 can be installed on the outer shell 1 along the slide groove 11. Since the cross-sections of the clamping block 1 7 and the clamping block 2 8 are wide at the top and narrow at the bottom, the two groove walls of the clamping groove 10 can clamp the clamping portion 9, thereby fixing the shell 1 3 and the shell 2 4 together.

[0042] Furthermore, a guide portion is provided at the rear end of the clamping portion 9, and the guide portion can quickly guide and position the locking member 6 so that the locking member 6 can enter the sliding groove 11.

[0043] like Figure 4 As shown, a positioning block 12 is protrudingly formed on the side wall surface of shell 13, and a positioning groove 13 adapted to the positioning block 12 is recessedly formed on the side wall surface of shell 2 4. When shell 1 3 and shell 2 4 are spliced, the positioning block 12 is placed in the positioning groove 13. The arrangement of the positioning block 12 and the positioning groove 13 can facilitate the alignment and splicing of shell 1 3 and shell 2 4, and when the locking piece 1 6 is installed on the outer shell 1, the radial limit position of shell 1 3 and shell 2 4 can be limited.

[0044] Furthermore, a locking block 14 is provided on shell 1 3 , and a locking groove 15 adapted to the locking block 14 is provided on shell 2 4 . When shell 1 3 and shell 2 4 are spliced ​​together, the locking block 14 is placed in the locking groove 15 to prevent shell 1 3 and shell 2 4 from separating.

[0045] like Figure 2-7 As shown, a second locking member 16 is installed on the outer shell 1. The second locking member 16 has the same function as the first locking member 6, and both are used to fix the shell 1 3 and the shell 2 4 together.

[0046] Specifically, a clamping block three 17 and a clamping block four 18 are respectively protruded on the outer side walls of the shell one 3 and the shell two 4. When the shell one 3 and the shell two 4 are spliced ​​together, the clamping block three 17 and the clamping block four 18 cooperate to form a clamping portion two 19; a clamping groove two 20 adapted to the clamping portion two 19 is formed in the locking member two 16, and the cross-sections of the clamping block three 17 and the clamping block four 18 are also wide at the top and narrow at the bottom, so that the locking member two 16 can be fixed to the clamping portion two 19. The difference between the locking member two 16 and the clamping member one is that the locking member two 16 is smaller in size and does not need to be moved.

[0047] Furthermore, locking member 2 16 is arranged in the space enclosed by locking member 1 6 and outer shell 1, and snap-in member 1 and locking member 2 16 cooperate to fix outer shell 1. When snap-in member 1 is installed on outer shell 1, locking member 2 16 can be enclosed inside it to prevent it from falling off and affecting the connection of outer shell 1.

[0048] Furthermore, the snap-fitting portion 19 is recessed to form an escape opening 21, which is located at the front end of the snap-fitting portion 19. The locking member 16 can enter from the escape opening 21 and be snap-fitted to the snap-fitting portion 19. The escape opening 21 provides an installation position for the locking member 16.

[0049] like Figure 2-7 As shown, the edge of the locking piece 16 is folded outward to form an abutment portion 22, and the inner wall of the locking piece 16 has an abutment groove 23, and a stopper 24 is arranged in the abutment groove 23; when the locking piece 6 is installed on the outer shell 1, the abutment portion 22 is movably placed in the abutment groove 23, and movably abuts the stopper 24, so that the locking piece 6 is fixed on the outer shell 1, and the abutment portion 22 cooperates with the groove wall of the abutment groove 23 to limit the locking piece 6 on the outer shell 1 to prevent the locking piece 6 from falling off due to excessive sliding. The abutment portion 22 cooperates with the stopper 24 to limit the locking piece 6 when it is partially placed on the outer shell 1, that is, the position where the locking piece 6 can be held by hand for vacuuming.

[0050] like Figure 8 As shown, the dust collecting device 5 has a cover body 25 and a cover cover 26. The cover body 25 is arranged at the front end of the outer shell 1 and is connected to the installation chamber 2. The front end of the cover cover 26 is hinged on the cover body 25 by a spring 27, and the rear end is movably connected to the cover button 28 arranged on the shell 3. The spring 27 makes the cover cover 26 always have a tendency to open. Therefore, pressing the cover button 28 can separate the rear end of the cover cover 26 from the outer shell 1, thereby unlocking the cover cover 26 to open it, and personnel can clean the inside thereof. The areas of the cover body 25 and the cover cover 26 are approximately the same. When the cover cover 26 is opened, its opening area is larger, which is convenient for personnel to clean. When the cover cover 26 needs to be closed, the personnel manually presses its rear end to be connected to the cover button 28 so that it is connected to the outer shell 1.

[0051] like Fig. 9 As shown, the dust suction device 5 has a dust suction power part 29, a closing part 30 and a cleaning sea handkerchief part 32. The dust suction power part 29 is arranged in the installation chamber 2, and is used to provide power for dust suction, and sucks dust through the dust suction port on the cover shell flip cover 26. The closing part 30 is used to close the installation chamber 2 and fix the dust suction power part 29 in the installation chamber 2 at the same time. The cover shell body 25 and the cover shell flip cover 26 cooperate with the closing part 30 to form a storage space for collecting dust. The cleaning sea handkerchief part 32 is arranged on the closing part 30 through the installation base 31.

[0052] Furthermore, the rear end of the mounting base 31 abuts against the front ends of the outer shell 1 and the closure 30 at the same time. The mounting base 31 has a stepped structure, and the rear end of the cover body 25 has a clamping portion that is adapted to the stepped structure of the mounting base 31. When the cover body 25 is installed on the outer shell 1, the clamping portion can fix the mounting base 31 on the outer shell 1 and the closure 30 to increase the stability of the overall structure of the handheld vacuum cleaner.

[0053] [Example 2]

[0054] like Fig.10 As shown, the configuration of this embodiment is substantially the same as that of embodiment 1, the only difference being that the locking member 16 is cancelled, and the outer shell 1 is fixed only by the locking member 16. At this time, a plurality of limit blocks 33 are provided on the locking member 6, and a limit groove 34 adapted to the limit block 33 is provided on the clamping portion 9. When the limit block 33 is placed in the limit groove 34, the locking member 6 is fixed on the outer shell 1. When the locking member 6 is fixed on the outer shell 1, it is convenient for personnel to stably grasp the vacuum cleaner through the locking member 6, and the extension length of the locking member 6 can also be changed by adjusting different limit blocks 33 to be placed in the limit groove 34.

[0055] [Example 3]

[0056] The configuration of this embodiment is substantially the same as that of the first embodiment, the only difference being that the locking member 6 is eliminated, the outer shell 1 is fixed by the locking member 16 , and the abutment portion 22 on the locking member 16 is eliminated.
