DETAILED DESCRIPTION

[0080] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0081] In the description of the present utility model, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the utility model product is usually placed when in use, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. "First" and "second" are only for the purpose of making the description easier to understand, without any other directional meaning, and cannot be used as a limitation on the present utility model.

[0082] like Figures 1 to 10 The present embodiment shows a hand-held vacuum cleaner assembly 100 for both blowing and sucking, comprising a vacuum cleaner main unit 10, a handle 20 fixed to the side wall of the vacuum cleaner main unit 10, a first functional head 30, and a second functional head 40. The vacuum cleaner main unit 10 comprises an internal fan assembly 11, an air inlet 12 at the first end d1, and an air outlet 13 at the second end d2. The fan assembly 11 is used to allow air to enter from the air inlet 12 and to be blown out from the air outlet 13.

[0083] like Figure 1 , Figure 3 , Figure 4 and Figure 7As shown, the vacuum host 10 has a host housing 50, which includes a peripheral shell portion 51, an air inlet shell portion 52 located at the first end d1, and an air outlet shell portion 53 located at the second end d2. Thus, the host housing 50 covers the fan assembly 11 inside it, the air inlet shell portion 52 covers the air inlet 12, and the air outlet shell portion 53 covers the air outlet 13, so that the various components of the vacuum host 10 are covered inside the host housing 50.

[0084] like Figure 2 As shown, when the dual-purpose blowing and suction handheld vacuum cleaner assembly 100 is used as a common handheld vacuum cleaner, the dust collecting bin 101 is detachably connected to the outer end of the air inlet shell 52, and then a suitable vacuuming function head 102 is connected to the outer end of the dust collecting bin 101, and the user can hold the handle 20 to perform vacuuming operations.

[0085] like Figure 4 and Figure 7 As shown, a first detachable structure c1 that matches each other is provided between the air inlet shell 52 and the first functional head 30, and a second detachable structure c2 that matches each other is provided between the air outlet shell 53 and the second functional head 40. The air inlet shell 52 is connected to the first functional head 30 to realize the vacuum function, for example, Fig. 9 As shown, the first functional head 30 is aligned with the air port of the vacuum bag to perform vacuuming. The air outlet shell 53 is connected to the second functional head 40 to realize the gap dust blowing function, for example, Fig.10 As shown, the second functional head 40 is aimed at the gap of the keyboard to clean the dust embedded therein. Thus, the dual-purpose handheld vacuum cleaner assembly 100 makes full use of the opposite gas flow directions of its air inlet 12 and air outlet 13, and cooperates with a specific detachable functional head to realize the function realization and application of multiple scenarios, meeting the user's demand for "one machine for multiple uses".

[0086] like Figures 4 to 6 As shown, the first functional head 30 includes a first connection cover 31 and a suction port 32 extending outward from the outer end surface of the first connection cover 31 and having a smaller diameter than the first connection cover 31. The first connection cover 31 is detachably connected to the air inlet shell 52, and the suction port 32 is used to realize the vacuuming function. Therefore, on the one hand, the suction port 32 with a smaller diameter can better match the air port of the vacuum bag, and on the other hand, when the airflow enters from the suction port 32 with a smaller diameter, the gas pressure is greater and the vacuuming efficiency is higher.

[0087] Specifically, a first annular connecting wall 54 is provided on the air inlet shell 52, and the caliber of the first connecting cover 31 of the first functional head 30 matches the first annular connecting wall 54. The first detachable structure c1 is provided between the first connecting cover 31 and the first annular connecting wall 54, and the first connecting cover 31 is connected to the first annular connecting wall 54, so that the first functional head 30 is detachably connected to the air inlet shell 52, that is, to the vacuum cleaner main unit 10.

[0088] The first detachable structure c1 includes a plurality of clamping ribs 55 protruding from the inner wall of the first annular connecting wall 54, and a plurality of clamping grooves 33 provided on the peripheral wall of the first connecting cover 31. The clamping grooves 33 include an inlet and outlet slot 34 located at the edge of the first connecting cover 31, and a limiting slot portion 35 extending from the inlet and outlet slot 34 to the peripheral wall of the first connecting cover 31.

[0089] When connecting, first align each clamping rib 55 with the corresponding clamping groove 33, and the clamping rib 55 enters the clamping groove 33 axially from the inlet and outlet slot 34; then slightly rotate the first functional head 30, and the clamping rib 55 enters the limiting groove 35 circumferentially, and the limiting groove 35 keeps the clamping rib 55 in the clamping groove 33, thereby forming a detachable connection between the first connection cover 31 and the first annular connection wall 54. The operation steps for disassembly are opposite to those for connection.

[0090] In other embodiments, the first detachable structure c1 may also adopt other detachable connection methods, for example, internal and external threads are provided between the first connection cover 31 and the first annular connection wall 54 for threaded connection, or elastic buckles are provided between the first connection cover 31 and the first annular connection wall 54 for buckle connection, or interference fit between the first connection cover 31 and the first annular connection wall 54 is used for interference connection. Of course, the detachable connection method adopted in this embodiment is not only simple in structure and process, but also convenient in connection and disassembly operations while ensuring a reliable connection. When the first functional head 30 completes the vacuuming operation and is removed from the air port of the vacuum bag, it is not easy to be pulled off the vacuum cleaner main unit 10.

[0091] like Figure 7 and Figure 8 As shown, the second functional head 40 includes a second connection cover 41 and a conical dust blowing nozzle 42 extending outward from the outer end surface of the second connection cover 41 and having a diameter gradually reduced from the inside to the outside. The second connection cover 41 is detachably connected to the gas outlet shell 53, and the conical dust blowing nozzle 42 is used to realize the vacuuming function. Therefore, the conical dust blowing nozzle 42 can not only more accurately align with smaller cleaning locations such as gaps and holes, but also increase the gas pressure of the airflow blown therefrom as much as possible to enhance the dust blowing effect.

[0092] Specifically, the air outlet housing 53 is provided with an air outlet fence 56 , which is recessed inward relative to the periphery of the air outlet housing 53 to form a second annular connecting wall 57 between the air outlet fence 56 and the periphery of the air outlet housing 53 .

[0093] The caliber of the second connecting cover 41 of the second functional head 40 matches the second annular connecting wall 57, and the second detachable structure c2 is arranged between the second connecting cover 41 and the second annular connecting wall 57. The second connecting cover 41 is connected to the second annular connecting wall 57 so that the second functional head 40 is detachably connected to the air outlet shell 53, that is, to the vacuum cleaner host 10.

[0094] The second connection cover 41 is inserted into the recess of the air outlet fence 56 , and the outer peripheral edge of the second connection cover 41 is interference-extruded with the inner wall of the second annular connection wall 57 to form a second detachable structure c2 , and a detachable connection is formed between the second connection cover 41 and the second annular connection wall 57 .

[0095] In other embodiments, the second detachable structure c2 may also adopt other detachable connection methods, for example, internal and external threads are set between the second connecting cover 41 and the second annular connecting wall 57 for threaded connection, or elastic clips are set between the second connecting cover 41 and the second annular connecting wall 57 for clip connection, or a connection method similar to the rib 55 and the slot 33 of the first detachable structure c1.

[0096] However, since the conical dust blowing nozzle 42 can directly perform dust blowing operation without secondary connection with other objects, the interference connection method adopted in this embodiment is the most suitable, while taking into account the convenience of assembly, structural simplicity and sufficient connection reliability. In addition, the air outlet fence 56 is recessed inward relative to the peripheral edge of the air outlet shell 53. On the one hand, the appearance of the vacuum cleaner main unit 10 is smoother and more beautiful. On the other hand, it is conducive to the air outlet shell 53 and its second annular connecting wall 57 to further expand more functional heads and realize more functional applications.

[0097] like Figure 1 and Figure 2 As shown, further, a dust display lamp 14 that can emit green light is also provided on the side wall of the vacuum main unit 10, and the dust display lamp is located on the side close to the air inlet 12. When the air inlet shell 52 of the dual-purpose handheld vacuum assembly 100 is installed with the dust collection bin 101 and the vacuum head 102 and used as a handheld vacuum cleaner, the dust display lamp 14 is turned on to emit green light to the front, so as to show the dirt such as dust and hair in front, guide the user to clean accurately, and improve the vacuuming efficiency. The advantage of using a dust display lamp 14 that emits green light is that the dust display effect of green light on dust and hair is better than that of light of other colors.

[0098] In this embodiment, the upper end of the handle 20 is connected to a side close to the air outlet 13, and a gap 21 is formed between the upper end of the handle 20 and the tail end of the dust indicator lamp 14. The outer end surface of the dust indicator lamp 14 does not exceed the outer end surface of the peripheral shell portion 51. The dust indicator lamp 14 is arranged on the vacuum cleaner host 10 instead of the handle 20, which can prevent the user's hand from pinching and blocking the emission of the green light, and the user is more comfortable when holding the handle 20. The gap 21 is formed between the dust indicator lamp 14 and the handle 20, which further improves the comfort of the user holding the handle 20 and leaves enough space for the user's fingers. The outer end surface of the dust indicator lamp 14 does not exceed the outer end surface of the peripheral shell portion 51, thereby providing sufficient space for the air intake shell portion 52 to install the functional head, and when the air intake shell portion 52 is installed with the dust collection bin 101, the emitted green light is not easily blocked by the dust collection bin 101.

[0099] Of course, in other embodiments, considering the ratio of the length of the dust indicator light 14 to the length of the vacuum cleaner main unit 10 , the upper end of the handle 20 may also be connected to the middle position of the vacuum cleaner main unit 10 , and the notch 21 may also be formed.

[0100] Furthermore, the peripheral shell 51, the shell of the handle 20, and the shell of the dust indicator 14 are integrally formed, so that the appearance of the dual-purpose handheld vacuum cleaner assembly 100 is more integrated, and the gaps and joints are reduced, thereby preventing dust and hair from entering the shell. Of course, in other embodiments, for example, when the handle 20 is rotatable, foldable or detachable relative to the vacuum cleaner main body 10, it may not be designed as an integral whole.

[0101] A switch 22 for controlling the fan assembly 11 and the dust indicator lamp 14 is provided on the side of the handle 20. The switch 22 and the dust indicator lamp 14 are not on the same plane. Figure 1 and Figure 2 As shown, the dust indicator light 14 is located on the left and right sides of the handle 20 rather than the front and back sides. This design allows the user to easily press the control switch 22 while holding the handle 20, and the switch 22 and the dust indicator light 14 are not easily obstructed by each other.

[0102] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.
