DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] It should be noted that the terms "first", "second" and "one end" in the specification and claims of the utility model are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, products or devices.

[0039] See also Figure 1 and Figure 2 The embodiment of the utility model provides a dust collecting device 100. The dust collecting device 100 includes a fan 11, a battery cell 13 electrically connected to the fan 11, a limit bracket 12 and a housing 14. The limit bracket 12 is respectively connected to the fan 11 and the battery cell 13, and defines the relative position of the fan 11 and the battery cell 13. The housing 14 has an installation opening, and the fan 11, the battery cell 13 and the limit bracket 12 can be installed in the housing 14 together through the installation opening.

[0040] Furthermore, the dust suction device 100 also includes a circuit board assembly 20, which electrically connects the fan 11 and the battery cell 13 to achieve electrical connection between the fan 11 and the battery cell 13; the fan 11, the battery cell 13 and the circuit board assembly 20 are all fixedly mounted on the limiting bracket 12 and form an integrated whole, so that the fan 11, the battery cell 13 and the circuit board assembly 20 have formed an integrated modular structure when they are not installed in the outer shell 14, making it simple and convenient to install the fan 11, the battery cell 13 and the circuit board assembly 20 into the outer shell 14.

[0041] The dust collecting device 100 provided by the embodiment of the utility model is provided with a limiting bracket 12. Since the fan 11 and the battery 13 are two electrical components with larger volumes in the dust collecting device 100, they usually need to be installed separately in the housing 14. In this application, the relative positions of the fan 11 and the battery 13 are limited on the limiting bracket 12. Therefore, during the assembly process of the dust collecting device 100, the assembler can first fix the fan 11 and the battery 13 on the limiting bracket 12, form an integrated structure with the limiting bracket 12, and install them into the housing 14 through the installation port. This avoids the user installing the fan 11 and the battery 13 one by one into the housing 14. This cumbersome installation method also avoids the situation where the fan 11 is first installed into the housing 14, and a long wire needs to be pulled out to electrically connect with the battery 13, and then the battery 13 is installed into the housing 14, which causes the wire to be too long and occupies volume. Therefore, the dust collecting device 100 provided in the embodiment of the utility model integrates the fan 11, the battery 13 and the limit bracket 12 through a modular design, thereby achieving the technical effect of simplifying the installation process and volume of the vacuum cleaner. Moreover, since the housing 14 may only include installation openings such as the air inlet 142 or the air outlet; the dust collecting device 100 provided in the utility model allows the installer to quickly install the fan 11 and the battery 13 into the housing 14, thereby significantly reducing the difficulty of installing the vacuum cleaner.

[0042] In one embodiment, the limiting bracket 12 has a first accommodating portion 121 and a second accommodating portion 123, the fan 11 is accommodated in the first accommodating portion 121, and the battery cell 13 is accommodated in the second accommodating portion 123. The first accommodating portion 121 and the second accommodating portion 123 can be a planar structure, or a cavity shell structure, providing an installation position for the fan 11 and the battery cell 13, and the form is not limited here.

[0043] Furthermore, the first accommodating portion 121 and the second accommodating portion 123 are arranged along the length direction of the housing 14, and the fan 11 and the battery cell 13 are also arranged along the length direction of the housing 14 corresponding to the first accommodating portion 121 and the second accommodating portion 123, and the fan 11 and the battery cell 13 are respectively arranged at both ends of the limiting bracket 12. Therefore, the fan 11, the battery cell 13 and the limiting bracket 12 are arranged along the length direction of the housing 14, and the limiting bracket 12 serves to connect and limit the position of the fan 11 and the battery cell 13. Although the outer shape of the housing 14 is varied, it often has an air inlet 142 and an air outlet, and the housing 14 may be a structure extending in a single direction, or a curved polygonal, irregular cylindrical structure, and a cavity is opened in the housing 14, and the cavity inside the housing 14 is connected to the air inlet 142 and the air outlet. Therefore, when the fan 11, the battery cell 13 and the limiting bracket 12 are arranged along the length direction of the housing 14, it is often more consistent with the extension direction of the internal space of the housing 14, so that the arrangement of the fan 11 and the battery cell 13 in the housing 14 is more reasonable and the space in the housing 14 is effectively utilized. When the housing 14 is a regular cylindrical shell, the single module formed by installing the above-mentioned electrical structure on the limiting bracket 12 can achieve simpler installation and fully utilize the stacking space.

[0044] Further, see Figures 3 to 5 as well as Figure 7a , the limiting bracket 12 includes a partition 1286, and the partition 1286 is arranged between the first accommodating portion 121 and the second accommodating portion 123. It should be noted that the first accommodating portion 121 and the second accommodating portion 123 can be a bracket with an accommodating space, and the first accommodating portion 121 and the second accommodating portion 123 can also be understood as the first accommodating chamber 122 and the second accommodating chamber 124, which will not be repeated later. In one embodiment, the limiting bracket 12 is divided into the first accommodating chamber 122 and the second accommodating chamber 124 by the partition 1286. The fan 11 is accommodated in the first accommodating chamber 122, and the battery cell 13 is accommodated in the second accommodating chamber 124. Figures 3 to 5 The situation shown is an example for explaining that the fan 11 and the battery cell 13 are at least partially accommodated in the corresponding first accommodation cavity 122 and the second accommodation cavity 124. The fan 11 and the battery cell 13 can also be completely accommodated in the first accommodation cavity 122 and the second accommodation cavity 124 in a one-to-one correspondence. Therefore, taking the connection relationship between the fan 11 and the battery cell 13 as an example, as shown in FIG. Figure 3 and Figure 4 As shown, the bottom surface and side walls of the fan 11 are connected to the limiting bracket 12, so that the bottom surface and side walls of the fan 11 can form a limiting relationship with the limiting bracket 12, for example, the bottom surface and side walls of the fan 11 are in a snap-fit ​​relationship with the limiting bracket 12, so that the limiting bracket 12 can achieve a better fixing effect on the fan 11. Therefore, the limiting bracket 12 and the battery 13 or other electrical appliances can also have the same connection and fixing effect.

[0045] Further, see Figure 4 and Figure 5 The installation opening of the first accommodating chamber 122 and the installation opening of the second accommodating chamber 124 are respectively provided at the two ends of the limiting bracket 12 along the length direction. As a result, the fan 11 and the battery cell 13 can be disassembled and assembled at the opposite ends of the limiting bracket 12, which not only makes the fan 11 and the battery cell 13 have a clear disassembly and assembly direction relative to the limiting bracket 12, but also helps to clarify the installation direction when the fan 11 and the battery cell 13 are installed in the housing 14 through the installation opening, for example, the end of the battery cell 13 away from the limiting bracket 12 is used as the end that is first inserted into the installation opening, thereby achieving a clear and quick installation method. Among them, the installation opening of the first accommodating chamber 122 is, for example, Figure 3 The first installation opening 125 shown in the figure and the installation opening of the second accommodating cavity 124 are, for example, Figure 5 The second mounting opening 127 is shown.

[0046] In addition, see Figure 6 The limiting bracket 12 may include: a first supporting structure 126 and a second supporting structure 128. The second supporting structure 128 is detachably connected to the first supporting structure 126; the first supporting structure 126 and the second supporting structure 128 jointly define the relative position of the fan 11 and the battery cell 13. Therefore, the fan 11 and the battery cell 13 may be first installed on the first supporting structure 126 or the second supporting structure 128, and then the first supporting structure 126 and the second supporting structure 128 are connected to achieve the limitation of the relative position of the fan 11 relative to the battery cell 13.

[0047] In one embodiment, for example Figure 6 As shown, the first support structure 126 and the second support structure 128 are connected to form a first accommodating portion 121 for accommodating the fan 11, and / or, the first support structure 126 and the second support structure 128 are connected to form a second accommodating portion 123 for accommodating the battery cell 13. The first support structure 126 and the second support structure 128 are buckled in the length direction of the limiting bracket 12, so that the fan 11 is sandwiched between the first support structure 126 and the second support structure 128. Therefore, the installer can first place the fan 11 on the second support structure 128, and then buckle the first support structure 126 and the second support structure 128 to achieve a stable connection between the fan 11 and the limiting bracket 12. In this installation method, the battery cell 13 can be directly inserted into the second support structure 128, or fixed to the second support structure 128 by means of clamping, gluing, etc. Or when the fan 11 is sandwiched between the first support structure 126 and the second support structure 128, the battery cell 13 is also sandwiched between the first support structure 126 and the second support structure 128. Thus, the first supporting structure 126 and the second supporting structure 128 are equivalent to two cover bodies that can be snap-connected.

[0048] See also Figure 6 , showing a more specific structural setting of a limiting bracket 12 in this embodiment. Among them, the limiting bracket 12 includes a first supporting structure 126 and a second supporting structure 128. The second supporting structure 128 is detachably connected to the first supporting structure 126. And the second supporting structure 128 has a joint 1282 and a clamping portion 1284 connected to the joint 1282. The first supporting structure 126 is detachably connected to the joint 1282 and forms a first accommodating chamber 122, and the fan 11 is arranged in the first accommodating chamber 122. The clamping portion 1284 forms a second accommodating chamber 124, and the battery cell 13 is arranged in the second accommodating chamber 124 and clamped with the clamping portion 1284. Therefore, the user can first clamp the battery cell 13 to the clamping portion 1284, and then place the fan 11 on the joint 1282, and then snap the joint 1282 and the first supporting structure together, so as to fix the fan 11 to the limiting bracket 12.

[0049] See also Figure 4 and Figure 6 , the first support structure 126 and the second support structure 128 can be detachably connected by snapping. And the first support structure 126 and the second support structure 128 are snapped to form an annular structure. The annular structure surrounds and connects the fan 11 and / or the battery cell 13, and the snap-in position of the first support structure 126 and the second support structure 128 is arranged on the inner side of the annular structure. The first support structure 126 is provided with a first snap-in portion (not shown in the figure), and the second support structure 128 is provided with a second snap-in portion (not shown in the figure). The first snap-in portion and the second snap-in portion are both arranged at the connecting end of the first support structure 126 and the second support structure 128, and the correspondingly connected first snap-in portion and the second snap-in portion are mutually concave-convex structures, and the concave-convex structure cooperates with the snap-in connection, so that after the first snap-in portion and the second snap-in portion are connected, they are hidden in the side walls of the first support structure 126 and the second support structure 128.

[0050] The annular structure may be, for example, Figure 4 The circular ring shown in the figure can also be other polygonal rings. Figure 4 and Figure 6 The illustrated situation is an example of a ring structure formed by the first support structure 126 and the joint portion 1282 being clamped together and arranged around the fan 11. Since the clamping position of the first support structure 126 and the second support structure 128 is arranged on the inner side of the ring structure, the radial dimension of the ring structure is reduced compared with the traditional screw fixing method, thereby achieving the technical effect of reducing the size of the dust collecting device.

[0051] Further, see Figure 7a and Figure 7bThe dust collecting device 100 may further include a buffer layer 18, which is sandwiched between the clamping portion 1284 and the battery cell 13. The buffer layer 18 may be made of a material having a buffering function, such as foam, a silicone layer, or a rubber layer, so as to protect the battery cell 13 and the clamping portion 1284 from compression damage caused by vibration or the like.

[0052] Further, see Figure 7a and Figure 8 The dust collecting device 100 may further include a second cover 17. The second cover 17 is disposed at the mounting opening, and one end of the battery cell 13 away from the clamping portion 1284 abuts against the second cover 17. Thus, the battery cell 13 can be better fixed in the housing 14. The mounting opening may be, for example, an air inlet or an air outlet. Figure 7a For example, if the installation opening is an air outlet, a vent for air outlet may be provided on the second cover 17. The second cover 17 may also be provided with a side wall wrapping the battery cell 13, and a step-shaped protrusion is provided to abut against the battery cell 13, thereby preventing the battery cell 13 from moving up and down.

[0053] In addition, referring to FIG. 7 , the dust collecting device 100 may further include a first cover 15. The fan 11, the battery cell 13 and the limit bracket 12 are installed in the outer shell 14, the first cover 15 is arranged at the installation opening, and the fan 11 is clamped between the limit bracket 12 and the first cover 15. Thus, after the fan 11, the battery cell 13 and the limit bracket 12 are installed in the outer shell 14, the installer can encapsulate the three in the outer shell 14 by installing the first cover 15 at the position of the installation opening. The installation opening where the first cover 15 is located is, for example, an air inlet, and the first cover 15 may be provided with a through hole for airflow to pass through. The first cover 15 may be connected to the outer shell 14, for example, by a snap-fit ​​fixing method.

[0054] In addition, see Figures 2 to 4 The part of the limiting bracket 12 that accommodates the fan 11, that is, the side wall of the first accommodating portion 121, can be provided with an air outlet so that the airflow generated by the fan 11 can flow in the housing 14.

[0055] Further, see Figure 7c and Fig. 9, the limiting bracket 12 has a partition 1286, and the partition 1286 separates the fan 11 and the battery cell 13. The dust collection device also includes a buffer, which is arranged between the limiting bracket 12 and the fan 11 to reduce the vibration of the fan 11 and the limiting bracket 12, which generates loud noise and easily damages the fan 11. The buffer specifically includes a first buffer 192 and a second buffer 194. The first buffer 192 is clamped between the first cover 15 and the fan 11, and is also clamped between the limiting bracket 12 and the fan 11. The second buffer 194 is clamped between the partition 1286 and the fan 11. By providing the first buffer 192 and the second buffer 194, the vibration generated by the fan 11 during operation can be reduced to drive the limiting bracket 12. The first buffer 192 and the second buffer 194 can be made of materials with buffering functions, such as silicone, rubber, etc.

[0056] Further, see Figure 7a The dust collecting device further includes a fastener 1288. The fastener 1288 is connected to the partition 1286 and is inserted into the second buffer 194. Thus, the second buffer 194 is fixed to the partition 1286. The fastener 1288 may be, for example, a screw, and a bottom bracket may be provided between the second buffer 194 and the partition 1286, and a circuit board may be sandwiched between the second buffer 194 and the fan 11, and the circuit board is electrically connected to the fan 11.

[0057] In addition, if Figure 7c As shown, when the limiting bracket 12 has a partition 1286 that separates the first accommodating chamber 122 and the second accommodating chamber 124, the partition 1286 may be provided with a through hole 1281 that connects the first accommodating chamber 122 and the second accommodating chamber 124. The fan 11 and the battery cell 13 are electrically connected through the through hole 1281. Figure 7a and Figure 7c For example, the fan 11 and the battery core 13 can be electrically connected via a wire passing through the through hole 1281 .

[0058] In addition, if Fig. 9 As shown, the limit bracket 12 does not form a closed space, and the side wall of the limit bracket 12 is an open structure with through holes. Therefore, a circuit board can be installed on the outside of the side wall of the limit bracket 12. The circuit board can be arranged corresponding to the through holes on the side wall and used as a main control circuit board and / or a light display circuit board. The circuit board can be electrically connected to the fan 11 and / or the battery cell 13. Since the limit bracket 12 does not form a closed space, the fan 11 and / or the battery cell 13 can be electrically connected to the circuit board by welding wires, and the welding process is relatively simple, and there is no need to reserve too long wires, thereby reducing the stacking space.

[0059] See also Fig.11, the dust collection device 100 may further include a circuit board assembly 20. The circuit board assembly 20 is arranged on the outside of the limiting bracket 12 and is electrically connected to the fan 11 and the battery cell 13. The circuit board assembly 20 may be connected to the limiting bracket 12, for example, by means of screw fastening, clamping, gluing, etc. Thus, while the limiting bracket 12 defines the relative position of the fan 11 and the battery cell 13, it also defines the relative position of either the fan 11 or the battery cell 13 and the circuit board assembly 20. The circuit board assembly 20 may, for example, receive user instructions and regulate the working states of the fan 11 and the battery cell 13. Thus, the installer can install at least two electrical structures and the circuit board electrically connected thereto in the housing 14 through the installation port through the single structure of the limiting bracket 12, thereby achieving the technical effect of further simplifying the installation process of the dust collection device 100. The circuit board assembly 20, the fan 11 and the battery cell 13 are all mounted on the limiting bracket 12, so that through this integrated modular installation design, it is avoided that any one of the circuit board assembly 20, the fan 11 and the battery cell 13 is first installed in the housing 14, and a longer wire is extended between the electrical appliance first installed in the housing 14 and the electrical appliance installed later to achieve electrical connection. For example, if the circuit board assembly 20 is first fixed inside the housing 14, the circuit board assembly 20 must first be electrically connected with a longer wire and the battery cell 13 that is not installed in the housing 14, and then the battery cell 13 is inserted into the housing 14. Therefore, the circuit board assembly 20, the fan 11 and the battery cell 13 are all assembled into an integrated module through the limiting bracket 12, which can not only improve the difficulty of assembly, but also reduce the length of the wire, thereby reducing the volume occupied by the electrical structure inside the housing 14.

[0060] Specifically, combined Fig.10 and Fig.11 The limiting bracket 12 includes a first accommodating portion 121 and a second accommodating portion 123 which are connected to each other. The radial dimension of the first accommodating portion 121 is greater than the radial dimension of the second accommodating portion 123. In one embodiment, the first accommodating portion 121 and the second accommodating portion 123 are accommodating cavities, respectively, and are cylindrical cavities. The radial dimension of the first accommodating portion 121 and the radial dimension of the second accommodating portion 123 are respectively the diameters of the first accommodating cavity 122 and the second accommodating cavity 124. Among them, the radial direction Y is perpendicular to the length direction Z. The circuit board assembly 20 includes: a first circuit board 22 and a second circuit board 24. The first circuit board 22 is arranged on the outside of the first accommodating portion 121; the second circuit board 24 is arranged on the outside of the second accommodating portion 123, and are electrically connected to each other. The first circuit board 22 and the second circuit board 24 are stacked.

[0061] Specifically, the radial dimension of the first accommodation portion 121 is, for example, Fig.10 The first radial dimension R1 shown in FIG. 1 is a radial dimension of the second receiving portion 123. Fig.10The radial dimension relationship between the first accommodating portion 121 and the second accommodating portion 123 depends on the size of the electrical structure they accommodate. Generally, the radial dimensions of the electrical structures accommodated in the first accommodating portion 121 and the second accommodating portion 123 are different, for example Fig.11 and Figure 7a The fan 11 and the battery cell 13 wrapped in the buffer layer 18 are shown. First, the fan 11, the limit bracket 12 and the battery cell 13 are arranged along the length direction Z. Combined with the radial dimensions and directions of the first accommodating portion 121 and the second accommodating portion 123 mentioned above, the limit bracket 12 and the electrical structure connected thereto can be more in line with the internal space layout of the outer shell 14, such as a cylindrical shape. Secondly, based on the different radial dimensions of the first accommodating portion 121 and the second accommodating portion 123, the first circuit board 22 is arranged on the outside of the first accommodating portion 121, and the second circuit board 24 is arranged on the outside of the second accommodating portion 123. The first circuit board 22 and the second circuit board 24 will appear as follows Fig.11 The stacked arrangement shown in FIG. 1 is a positional relationship, that is, the first circuit board 22 and the second circuit board 24 are located in different planes along the radial direction Y, so that the first circuit board 22 and the second circuit board 24 make full use of the first accommodating portion 121 and the second accommodating portion 123 through the above arrangement. Fig.11 The space arrangement shown is larger at the top and smaller at the bottom, and the fixed connection between the limit bracket 12 and the shell 14, that is, the screw position is arranged in a larger-at-top-smaller-at-bottom manner, and the screw position is set on the outside of the second accommodating portion 123, so that the screwdriver can enter the inside of the shell 14 to tighten the screws and fix the position of the limit bracket 12, thereby achieving the technical effect of fully utilizing the space and reducing the external dimensions.

[0062] Specifically, the first circuit board 22 is, for example, a light display circuit board, on which a plurality of LED lights may be arranged. A digital tube frame is arranged above the plurality of LED lights, which divides the LED lights into a plurality of display areas, and a luminous film coated with fluorescent powder is attached above the digital tube frame to play a focusing role, which can convert the scattered light of the LED into a pattern luminous display. The second circuit board 24 is, for example, a main control circuit board, on which a button is arranged. Since the button protrudes from the surface of the second circuit board 24, the space arrangement of the limiting bracket 12 is larger at the top and smaller at the bottom, and two circuit boards are arranged outside the first accommodating portion 121 and the second accommodating portion 123, so that the outside of the second accommodating portion 123 has a space for button assembly, which makes the most of the reasonable arrangement of space and reduces the size of the dust collection device. The first circuit board 22 and the second circuit board 24 can be connected by pin welding, and the fan 11 and the battery cell 13 are electrically connected to the second circuit board 24.
