Description
Technical Field
[0001] This utility model relates to a handheld vacuum cleaner, specifically a folding handheld vacuum cleaner. Background Technology
[0002] Currently, handheld vacuum cleaners mainly consist of a main unit and a dustbin mounted on it. The front of the dustbin typically has a suction hose for easy access to narrow corners, while the rear of the main unit usually has a handle for easy gripping. For convenient storage and portability, the suction hose and handle are often designed with a foldable structure, specifically folding the hose to one side of the dustbin and main unit, and the handle to the opposite side. To improve suction efficiency, a vacuum attachment is often attached to the hose's end. However, in handheld vacuum cleaners with this folding structure, the suction hose and attachments are exposed on the sides of the dustbin and main unit when folded. This not only makes the folded handheld vacuum cleaner bulky and unsightly, but also makes it easy to bump into the exposed attachments if they are dirty, significantly reducing the user experience. 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 foldable handheld vacuum cleaner with a beautiful folding shape and a better user experience.
[0004] The technical problem of this utility model is solved by the following technical solution:
[0005] A foldable handheld vacuum cleaner includes a main unit and a dustbin mounted on the main unit. The dustbin has a rotatably mounted suction pipe, and the main unit has a rotatably mounted handle. When the suction pipe is rotated outward relative to the dustbin and opens to seal and connect with the dustbin, and the handle is also rotated outward relative to the main unit, the handheld vacuum cleaner is in use. When the suction pipe is rotated inward relative to the dustbin and folded onto the dustbin, and the handle is also rotated inward relative to the main unit and folded onto the suction pipe, the handheld vacuum cleaner is in a folded and stored state.
[0006] The rear end of the suction pipe is hinged to both sides of the dustbin via a pair of rear hinge feet, and a suction attachment is installed at the front end.
[0007] The suction pipe has a suction port at its rear end, and a corresponding dust inlet is provided on the dust bin. The suction pipe rotates outward relative to the dust bin and opens, causing the suction port to seal and connect with the dust inlet.
[0008] The rear hinge foot is equipped with a locking switch, which can be used to unlock or lock the dust suction pipe in either the unfolded or folded state relative to the dustbin.
[0009] The vacuuming accessory includes a cleaning tube and a cleaning head located at the front end of the cleaning tube. The rear end of the cleaning tube is retractably inserted into the front end of the vacuuming tube via a control switch.
[0010] The front end of the handle is hinged to both sides of the main unit via a pair of front hinge feet, and the rear end is a suspended grip part.
[0011] The handle is equipped with a main switch for controlling the operation of the main unit.
[0012] The handle is equipped with a gear button, and the main unit is equipped with several gear slots. When the handle is rotated outward, the gear button can be selectively engaged in different gear slots to fix the unfolding angle of the handle.
[0013] The dustbin is detachably and sealed at the front end of the main unit, which is also equipped with a disassembly button, which controls the installation, locking, unlocking, and disassembly of the dustbin.
[0014] The handle contains a battery, and a charging port and a charging indicator light are located on the side of the handle.
[0015] Compared with existing technologies, this utility model mainly features a rotating suction pipe mounted on the dustbin and a rotating handle mounted on the main unit. When the suction pipe rotates outward relative to the dustbin, sealing and connecting the suction pipe to the dustbin, and the handle also rotates outward relative to the main unit, the handheld vacuum cleaner is in use. When the suction pipe rotates inward relative to the dustbin and folds onto the dustbin, and the handle also rotates inward relative to the main unit and folds onto the suction pipe (specifically, the suction pipe is inside and the handle is outside, with the handle neatly embracing the suction pipe), the handheld vacuum cleaner is in a folded and stored state. Therefore, the improved structure, by folding the suction pipe and handle in the same place, especially with the handle folded onto and embracing the suction pipe, not only makes the folded handheld vacuum cleaner more aesthetically pleasing but also conceals the suction pipe with the suction attachments, preventing direct exposure. Even if dirt adheres to the suction attachments, the concealed design prevents them from being easily touched, thus greatly improving the user experience. Attached Figure Description

[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] A foldable handheld vacuum cleaner, such as Figure 1 , Figure 4 As shown, this is a small handheld household appliance that can be used for vacuuming and is convenient to carry. Its structure mainly consists of a vacuum hose 3, a dustbin 2, a main unit 1, and a handle 4. The vacuum hose 3 is rotatably mounted on the dustbin 2, and the dustbin is detachably and sealed to the front end of the main unit 1. Figure 1 The left end of the main unit is shown in the unfolded use state, with handle 4 rotated and mounted on the main unit 1.
[0026] The main unit 1 is usually equipped with a fan 12 to provide suction power. After the fan is started, it can act on the dust bin 2 through the air inlet 11 at the front of the main unit to form negative pressure suction. The main unit 1 also needs to be designed with an exhaust port (not shown in the figure) to facilitate exhaust after the fan is started. The main unit switch 41, which is used to control the operation of the main unit 1, that is, to control the opening and closing of the fan 12 in the main unit 1, is usually set on the handle 4 for easy operation.
[0027] Meanwhile, the dust bin 2 is also equipped with a HEPA filter cover 6 as a filter component. The HEPA filter cover completely covers the air intake 11 to form an air intake filter, thereby preventing dust and other impurities in the dust bin 2 from directly entering the fan 12.
[0028] The dustbin 2 can be made of transparent material, so that users can observe the dust level in the dustbin in real time and make it convenient to clean it in a timely manner.
[0029] The front end of the main unit 1 is also provided with a disassembly button 7, which controls the installation, locking or unlocking of the dustbin 2. Usually, when the dustbin 2 is fitted into the front end of the main unit 1, the disassembly button 7 will automatically form an elastic snap-lock, at which point the dustbin 2 cannot be removed from the front end of the main unit 1. Then, pressing the disassembly button 7 will release the snap-lock and unlock the dustbin 2, which can then be removed from the front end of the main unit 1 for cleaning.
[0030] The rotating mounting structure of the suction pipe 3 on the dustbin 2 is such that the rear end of the suction pipe 3 is hinged to both sides of the dustbin 2 by a pair of parallel rear hinge feet 30. Therefore, the suction pipe 3 can rotate outward or fold inward relative to the dustbin 2 around the pair of rear hinge feet 30.
[0031] Furthermore, a locking switch 8 is provided on the rear hinge leg 30, which is used to unlock or lock the dust suction pipe 3 in its unfolded or folded state relative to the dustbin 2. In this embodiment, for example... Figure 3 , Figure 4 The diagram shows an elastic lever as the locking switch 8. Specifically, when the vacuum cleaner hose 3 rotates outward relative to the dustbin 2 and unfolds to its final position, the elastic lever automatically engages and locks the hose in this unfolded state. The vacuum cleaner hose 3 cannot rotate relative to the dustbin 2 until the lever is disengaged, allowing the hose 3 to rotate and fold relative to the dustbin 2. Similarly, when the vacuum cleaner hose 3 rotates inward relative to the dustbin 2 and folds to its final position, the elastic lever automatically engages and locks the hose, or the hose is manually disengaged to unlock it.
[0032] In addition, the rear end of the suction pipe 3 is provided with a suction port 31, and the dust bin 2 is provided with a corresponding dust inlet 21. When the suction pipe 3 rotates outward relative to the dust bin 2 and unfolds, usually when it is fully unfolded and automatically and elastically locked by the locking switch 8, it will cause the suction port 31 to seal and connect with the dust inlet 21. In this way, when the handheld vacuum cleaner is working, the negative pressure suction generated in the dust bin 2 will act on the suction pipe 3 in sequence through the dust inlet 21 and the suction port 31.
[0033] A valve plate 211 is also designed inside the dust inlet 21. Under normal conditions, the valve plate will directly block the dust inlet 21 and play the role of one-way entry into the dust inlet 21. That is to say, when the handheld vacuum cleaner is working, the dust and other impurities sucked in by the suction pipe 3 can pass through the suction port 31 and the dust inlet 21 in sequence and push open the valve plate 211 to enter the dust bin 2. However, when the suction pipe 3 is rotated inward relative to the dust bin 2 and folded on the dust bin to expose the dust inlet 21, the dust and other impurities in the dust bin 2 will be blocked by the valve plate 211 and will not fall out through the dust inlet 21.
[0034] The front end of the suction pipe 3 is equipped with a suction attachment 5. This suction attachment can be of many types, such as a cleaning brush or a cleaning wipe. The suction attachment in this embodiment is as follows: Figure 1 As shown, it includes a cleaning tube 51 and a cleaning head 52 located at the front end of the cleaning tube. The cleaning head can be a cleaning brush. The rear end of the cleaning tube 51 is telescopically inserted into the front end of the vacuum tube 3 via a control switch 53. Therefore, in actual use, if dust or other impurities in a narrow corner are far away, the cleaning tube 51 can be extended by operating the control switch 53, thereby extending the vacuum tube 3.
[0035] The front end of the handle 4 is hinged to both sides of the main unit 1 via a pair of parallel front hinge feet 40. Therefore, the handle 4 can rotate outward or fold inward relative to the main unit 1 around the pair of front hinge feet 40. The rear end of the handle 4 is a suspended grip part, which is mainly for the convenience of the user to hold.
[0036] The handle 4 contains a circuit board and a battery 43. The circuit board is used to control the operation of the host 1 in conjunction with the host switch 41 on the handle 4. The battery is usually a rechargeable battery, so the side of the handle 4 needs to be equipped with a charging port 44 and a charging indicator light 45.
[0037] The handle 4 is equipped with a gear button 42, which is a spring-loaded button structure. The main unit 1 is equipped with several gear slots 13. In this embodiment, for example... Figure 7 As shown, the slots are arranged in an arc along the outer circumference of the rear end of the main unit, that is, as... Figure 1 The image shows the right end of the main unit in its unfolded state. When the handle 4 is rotated outwards to unfold, the gear button 42 can selectively engage with different gear slots 13, thereby fixing the various unfolding angles of the handle 4. Specifically, the gear button 42 can automatically and elastically engage with the gear slot 13 to lock the unfolding angle of the handle 4. Only by pressing the gear button 42 to disengage from the current gear slot 13 can the handle 4 continue to rotate relative to the main unit 1 to select a new usage angle and lock it.
[0038] The working process of this utility model is as follows: When the suction pipe 3 rotates outward relative to the dustbin 2 and unfolds, it causes the suction port 31 to seal and connect with the dust inlet 21, that is, the suction pipe 3 seals and connects with the dustbin 2, and the handle 4 also rotates outward relative to the main unit 1. At this time, the handheld vacuum cleaner is in use. When the suction pipe 3 rotates inward relative to the dustbin 2 and folds onto the dustbin, and the handle 4 also rotates inward relative to the main unit 1 and folds onto the suction pipe 3, specifically, the suction pipe 3 is inside and the handle 4 is outside, and the handle 4 just holds the suction pipe 3 inside. At this time, the handheld vacuum cleaner is in the folded storage state.
[0039] Therefore, the improved structure folds the vacuum tube 3 and the handle 4 in the same place. In particular, the handle 4 is stacked on the vacuum tube 3 and hugs the vacuum tube. This makes the folded handheld vacuum cleaner more aesthetically pleasing and also allows the vacuum tube 3, which is equipped with the vacuum attachment 5, to be concealed and avoid direct exposure. In other words, even if there is dirt on the vacuum attachment 5, it will not be directly exposed and easily touched because of the concealed design, thus greatly improving the user experience.
