Description

A portable vacuum cleaner Technical Field

[0001] This utility model relates to a vacuum cleaner, specifically a portable vacuum cleaner. Background Technology

[0002] Currently, while handheld vacuum cleaners on the market are slim, compact, and easy to hold, their non-foldable design makes them difficult to carry. This is because the main unit, dustbin, and handle are all integrated into one unit, making these slim vacuum cleaners difficult to store and carry. Furthermore, the suction port or attachments installed within it are usually located at the front of the main unit and connected to the dustbin. This requires the user to hold the main unit at a certain angle to properly aim the suction port or attachments at the dirty surface. This handheld action is tiring for users, and the size of the vacuum cleaner makes it difficult to reach into narrow corners or crevices. Even if it is managed to reach them, the length of the vacuum cleaner limits the optimal suction position, thus restricting its use and affecting its cleaning performance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a portable vacuum cleaner that is convenient to store and carry, reduces the restrictions on the occasion of use, and has a better dust collection effect.

[0004] The technical problem of this utility model is solved by the following technical solution:

[0005] A portable vacuum cleaner includes a main unit, a dustbin and a handle mounted on the main unit. The main unit has an air intake that communicates with the dustbin. The handle is rotatably mounted on the main unit and can be folded inward or unfolded outward. The dustbin has a suction pipe that is rotatably mounted on and communicates with the dustbin. The suction pipe can be folded inward or unfolded outward.

[0006] One end of the suction pipe is hinged to the dustbin to form a rotation and connect to the dustbin, and the other end is equipped with a suction attachment.

[0007] The aforementioned vacuuming accessory is a cleaning tube with a cleaning head, which is telescopically inserted into the other end of the vacuum tube, and a telescopic control switch is provided on the vacuum tube.

[0008] The suction pipe is equipped with a locking switch that controls the rotation angle of the suction pipe relative to the dustbin.

[0009] One end of the handle is hinged to the main unit to allow rotation, while the other end is suspended in the air as a gripping end.

[0010] The dustbin is detachably installed at the front of the main unit, the handle is rotatably installed on the side of the main unit, and the suction pipe is rotatably installed on the side of the dustbin. The side of the main unit and the side of the dustbin are two opposite sides.

[0011] The inward rotation of the handle and the vacuum tube is a relative rotation, and the outward rotation of the handle and the vacuum tube is a counter-rotation.

[0012] The air intake is located at the front end of the main unit, and the rear end of the main unit is provided with an exhaust air outlet, on which an air blowing accessory is installed.

[0013] The main unit is equipped with a disassembly button for locking or unlocking the detachable dustbin.

[0014] The handle is equipped with a main switch for controlling the operation of the main unit.

[0015] Compared with existing technologies, this utility model mainly features a rotatably mounted handle on the main unit and a rotatably mounted suction pipe connected to the dustbin. This allows for significant reduction in the overall size of the vacuum cleaner when the handle is folded inwards onto the main unit and the suction pipe is also folded inwards onto the dustbin, facilitating storage and portability. When the handle and suction pipe are unfolded outwards, the user simply needs to hold the handle and align the suction attachment at the end of the suction pipe with the dirty work surface to vacuum. In other words, the vacuum cleaner can be used normally even when unfolded. Simultaneously, vacuuming... The attachments can also rotate flexibly with the suction tube, allowing users to adjust the suction position of the attachments by rotating the suction tube. This enables users to maintain the most comfortable handheld position to vacuum various locations, eliminating hand fatigue. Furthermore, in narrow corners or crevices, the smaller suction tube allows the attachments to reach into these areas. By extending the suction tube in conjunction with the attachments, the attachments can be positioned optimally for vacuuming, greatly reducing limitations on the vacuum cleaner's usability and providing better suction.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

Suction hose, 41. Locking switch, 42. Telescopic control switch, 43. Gear slot, 5. Suction accessory, 51. Cleaning hose, 52. Cleaning head.

[0028] A portable vacuum cleaner, as shown in Figures 1, 3, 6, and 7, mainly consists of a main unit 1, an air outlet 11 located at the rear of the main unit, an air intake 12 located at the front of the main unit, a dustbin 2 detachably mounted at the front of the main unit, a handle 3 rotatably mounted on the main unit, and a suction pipe 4 rotatably mounted on the dustbin.

[0029] The main unit 1 has a disassembly button 21 on the top front surface, which can be used to lock or unlock the detachable installation of the dust bin 2 and the main unit front. When the dust bin 2 and the main unit are assembled together, the air intake 12 is directly connected to the dust bin 2. When the dust bin 2 is disassembled from the main unit front by disassembly button 21, the dust suction pipe 4 on the dust bin will be disassembled together, and the air intake 12 will be directly exposed.

[0030] The main unit 1 is usually equipped with a fan (not shown in the figure) to provide the suction power of the vacuum cleaner. After the fan is started, it can act on the dust bin 2 through the air inlet 12 to form a negative pressure suction, and exhaust air out through the air outlet 11. The main unit switch 31, which controls the operation of the main unit, that is, controls the opening and closing of the fan in the main unit 1, is usually set on the handle 3 for easy operation.

[0031] Of course, in this embodiment, as shown in Figures 8 and 9, the dustbin 2 can be removed from the front end of the main unit 1, and the blower attachment 13 can be installed on the blower port 11. At this time, after the fan is started by controlling the main unit switch 31, the suction port 12 can directly draw air from the outside, and then the air is exhausted from the blower port 11 to the outside through the blower attachment 13 to form a blower. At this time, the vacuum cleaner can also be used as a blower. For example, it can blow out the dust and impurities hidden in deep crevices before vacuuming, so that the vacuum cleaner has the dual function of vacuuming and blowing.

[0032] The handle 3 is rotatably mounted on the side of the main unit, and the suction pipe 4 is rotatably mounted on the side of the dustbin. The side of the main unit and the side of the dustbin are two opposite sides. The purpose of this design is to allow the handle 3 and the suction pipe 4 to rotate independently, thereby avoiding positional interference when they rotate at the same time.

[0033] Meanwhile, the suction pipe 4 is hinged to the dustbin 2 at one end, which is the rear end of the suction pipe shown in Figure 3, to form a rotation and connect to the dustbin. The suction attachment 5 is installed at the other end, which is the front end of the suction pipe shown in Figure 3. The handle 3 is also hinged to the main unit 1 at one end, which is the front end of the handle shown in Figure 3, to form a rotation. The other end, which is the rear end of the handle shown in Figure 3, is suspended in the air as a grip end.

[0034] At this time, the handle 3 is either folded inwards onto the main unit 1 or unfolded outwards, and the suction pipe 4 is either folded inwards onto the dustbin 5 or unfolded outwards. In other words, the inward rotation of the handle 3 and the suction pipe 4 is relative rotation as shown in Figure 1, and the outward rotation of the handle 3 and the suction pipe 4 is opposite rotation as shown in Figure 3.

[0035] The suction pipe 4 is equipped with a locking switch 41 that controls the rotation angle of the suction pipe relative to the dustbin 2. Currently, there are many designs for locking switches. In this embodiment, as shown in Figure 4, the locking switch 41 is a flexible button. Correspondingly, several circumferentially distributed stop slots 43 are provided on the side of the dustbin at the rear end of the suction pipe. Each stop slot represents a rotation angle of the suction pipe 4. When the locking switch 41 enters the stop slot 43, the rotation of the suction pipe 4 relative to the dustbin 2 is locked, that is, the rotation angle of the suction pipe 4 is locked. When the locking switch 41 disengages from the stop slot 43, the suction pipe 4 can rotate flexibly relative to the dustbin 2.

[0036] The vacuuming attachment 5 is a cleaning tube 51 with a cleaning head 52. The cleaning tube is telescopically inserted into the other end of the vacuum tube 4, that is, into the front end of the vacuum tube. A telescopic control switch 42 is provided on the vacuum tube 4 to lock or unlock the telescopic length of the cleaning tube 51 in the front end of the vacuum tube 4.

[0037] The cleaning head 52 can be selected from the brush shown in Figure 6 or the cleaning wipe shown in Figure 7, or other various cleaning accessories.

[0038] Alternatively, in actual use, the vacuum attachment 5 can be omitted, in which case the port at the front end of the vacuum tube 4 can be used directly as a vacuum port. Or, the vacuum attachment 5 can be without the cleaning head 52, and only have a cleaning tube 51. In this case, the port at the front end of the cleaning tube can also be used directly as a vacuum port, and the length of the vacuum port can be extended through the cleaning tube 51.

[0039] This invention allows the handle 3 to be rotated inward and folded onto the main unit 1, and the suction pipe 4 to be rotated inward and folded onto the dustbin 2, which greatly reduces the size of the entire vacuum cleaner and makes it convenient to store and carry. When the handle 3 is rotated outward and unfolded, the suction pipe 4 is also rotated outward and unfolded. At this time, the user only needs to hold the grip end of the handle 3 and align the suction attachment 5 at the front end of the suction pipe with the dirty working surface to perform vacuuming. In other words, the entire vacuum cleaner can be used normally when unfolded.

[0040] In particular, the vacuum attachment 5 can also rotate flexibly with the vacuum hose 4. Not only can the vacuum attachment 5 be adjusted by the rotation angle of the vacuum hose, allowing the user to maintain the most comfortable hand position to vacuum various locations, eliminating fatigue from handheld use, but also in some narrow corners or crevices with small gaps, the smaller vacuum hose can be used to extend the vacuum attachment into these areas. Furthermore, by using the extension and retraction of the vacuum hose and attachment, the attachment can be delivered to the best vacuuming position, greatly reducing the limitations of the vacuum cleaner's usage and providing better vacuuming performance.

[0041] The embodiments described above are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
