Description

Technical Field

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

[0002] The structure of a handheld vacuum cleaner mainly includes the main unit and a dustbin installed at the front of the main unit. The dustbin has a suction port. Since the suction port is directly located on the dustbin, this type of handheld vacuum cleaner is only suitable for use in work environments where space is not restricted. If you encounter a work environment with limited space, the dustbin takes up a large volume, which will prevent the suction port from directly reaching into the confined space. If the suction port is designed as a thin, long tubular component, that is, a thin suction tube is designed on the dustbin, although the problem of vacuuming in confined spaces is solved, it will make the overall length of the handheld vacuum cleaner too large, affecting storage and portability. Of course, some designs use a rotating and folding structure for the vacuum hose. The hose can be rotated outwards relative to the dustbin for use or rotated inwards for storage. While this solves the aforementioned technical problems, the connection between the hose and the dustbin is not constant. Therefore, a sealing structure is necessary for maintaining this connection. However, in actual use, the frequent rotation of the hose relative to the dustbin significantly reduces the sealing performance of this structure. For example, when the handheld vacuum cleaner is in use, the reduced sealing performance between the rotating hose and the dustbin can lead to air leakage, greatly affecting the product's suction power. Furthermore, the hose often accumulates dirt after use, and since the folded hose is directly exposed on the main unit's surface, this dirt can easily contaminate the user's fingers or clothing. Additionally, while some handles are designed with a rotating and folding structure, they typically only have two locking positions: an unfolded position for use and a folded position for storage. This doesn't meet the user's need for multiple grip angles. 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 that can ensure the vacuuming effect during use, prevent the user from touching and getting dirty when stored, and allow the user to hold the handle at multiple usage angles.

[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 front end of the main unit. The dustbin has a suction port, a suction hose, and a handle. The handle is rotatably mounted on the rear end of the main unit. When the handheld vacuum cleaner is in use, the handle rotates outward relative to the main unit to various usage angles, and the dustbin can be directly vacuumed through the suction port or the end of the suction hose can be detachably inserted into the suction port for vacuuming. When the handheld vacuum cleaner is in a folded state, the suction hose is removed from the suction port and detachably attached to the outer surface of the main unit by the outer tube wall, and the handle rotates inward relative to the main unit and folds onto the suction hose.

[0006] The handle is equipped with a latch, and correspondingly, multiple position slots are provided at the rear end of the main unit. These multiple position slots are arranged sequentially in the circumferential direction of the handle's rotation trajectory relative to the rear end of the main unit, and the latch can selectively engage with different position slots to lock the handle at various usage angles.

[0007] The latch extends elastically from the front end of the handle via a latch spring and engages with the gear position groove; a button is provided on the outside of the handle, and pressing the button overcomes the elastic force of the latch spring to drive the latch to retract and disengage from the gear position groove.

[0008] The latch has a slot with a wedge-shaped surface. The button is pressed against the wedge-shaped surface by a wedge block, and when the button is pressed, the wedge block is pushed to slide along the wedge-shaped surface, thereby driving the latch to retract.

[0009] The outer wall of the suction tube is provided with inserts, and a corresponding slot is provided on the outer surface of the main unit. The suction tube is slidably inserted into the slot via the inserts, and thus can be detachably attached to the outer surface of the main unit.

[0010] The front end of the suction pipe is equipped with a telescopic cleaning head, and the rear end of the suction pipe is detachably inserted into the suction port.

[0011] The dustbin is detachably sealed and installed at the front of the main unit. The front of the main unit is also equipped with a disassembly button, which controls the installation, locking, unlocking, and disassembly of the dustbin.

[0012] The front end of the handle is hinged to both sides of the rear end of the main unit via a pair of hinge feet, forming a rotatable installation, while the rear end of the handle is a suspended gripping end.

[0013] The main unit is equipped with a dust suction fan, and a sealed dust suction channel is provided between the main unit and the dust bin. The dust bin is equipped with a filter cover that covers the dust suction channel.

[0014] The handle contains a battery and control circuit board that power the main unit, and the handle also has a main unit switch, a charging port and a charging indicator light on the outside.

[0015] Compared with existing technologies, this utility model mainly adds a rotatable handle mounted at the rear of the main unit and an independently configured suction hose to the structure of the handheld vacuum cleaner. When the handheld vacuum cleaner is in use, the handle rotates outward relative to the main unit to various operating angles, allowing the dustbin to be directly cleaned through the suction port or the suction hose end to be detachably inserted into the suction port. When the handheld vacuum cleaner is in storage, the suction hose is detached from the suction port and detachably attached to the outer surface of the main unit via the outer tube wall, while the handle rotates inward relative to the main unit and folds onto the suction hose. Clearly, because the suction hose is connected or disconnected from the suction port on the dustbin via a plug-in method, it offers advantages over traditional rotating and folding designs. The folding structure has lower requirements for sealing performance, thus preventing air leakage during use and greatly ensuring the product's suction effect. Furthermore, when the suction tube is removed and attached to the outer surface of the main unit, it can be concealed by the folded handle. This structure better prevents accidental contact and soiling of the suction tube during storage. Additionally, a latch is located inside the handle, and correspondingly, multiple position slots are located at the rear of the main unit. These slots are arranged circumferentially according to the handle's rotation trajectory relative to the rear of the main unit. The latch can selectively engage different position slots to lock the handle at various usage angles, thus meeting the user's needs for holding the handle at multiple angles.

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

[0025] Foldable handheld vacuum cleaners, such as Figure 6 , Figure 7 As shown, this is a small handheld household appliance for vacuuming and easy portability. Its structure mainly consists of a main unit 1, a dustbin 2 mounted on the front of the main unit, a handle 4 mounted on the rear of the main unit, and an independently configured suction hose 3. This embodiment uses... Figure 1 The bottom of the view shown represents the front end of the handheld vacuum cleaner, and the top of the view represents the rear end of the handheld vacuum cleaner.

[0026] The main unit 1 is usually equipped with a vacuum fan 9 to provide suction power. After the vacuum fan is started, it can act on the dust bin 2 through the vacuum channel 10 that is sealed between the main unit 1 and the dust bin 2 to form a negative pressure suction. The main unit 1 also needs to be designed with an exhaust port (not shown in the figure) to facilitate the exhaust after the vacuum fan 9 is started. The main unit switch 6, which is used to control the operation of the main unit 1, that is, to control the opening and closing of the vacuum fan 9 in the main unit 1, is usually set on the handle 4 for easy operation.

[0027] The dust bin 2 is equipped with a HEPA filter cover as a filter component. The filter cover 22 completely covers the dust suction channel 10 to form a suction filter, thereby preventing dust and other impurities in the dust bin 2 from directly entering the dust suction fan 9.

[0028] The dustbin 2 can be made of transparent material, so that users can observe the storage status of the dustbin in real time and clean it in a timely manner. The dustbin 2 is provided with a suction port 21, that is, the dustbin has a suction port at the front end to facilitate the suction of dust.

[0029] The front end of the main unit 1 is also provided with a disassembly button 5, 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 5 will automatically form an elastic snap-lock, at which point the dustbin 2 cannot be removed from the front end of the main unit. Then, pressing the disassembly button 5 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 handle 4 is equipped with a battery 44 that powers the host 1 and a control circuit board 45. The handle 4 is equipped with a host switch 6, a charging port 41 and a charging indicator light 42.

[0031] The front end of the handle 4 is hinged to both sides of the rear end of the main unit 1 via a pair of hinge feet 43, forming a rotatable installation. The rear end of the handle is a suspended grip end, which is convenient for users to hold and use.

[0032] Meanwhile, the user can hold the rear end of the handle and form multiple usage angles around the front end of the handle. The specific structure is as follows: the handle 4 is provided with a latch 8, and correspondingly, multiple position slots 11 are provided at the rear end of the main unit. These multiple position slots are arranged sequentially on the outer surface of the rear end of the main unit in the circumferential direction of the handle's rotation trajectory relative to the rear end of the main unit. The latch 8 can be selectively engaged into different position slots 11 to lock the various usage angles of the handle 4, thereby meeting the user's need to hold the handle to form multiple usage angles.

[0033] Moreover, the latch 8 is mainly extended from the front end of the handle by the latch spring 82 inside the handle 4 and is engaged in the gear position groove 11. In other words, under normal conditions, the latch 8 is always extended from the front end of the handle due to the elastic push of the latch spring 82. This is so that when the front end of the handle is rotated to a suitable operating angle, the latch 8 can automatically engage in the corresponding gear position groove 11 to form a lock.

[0034] The latch 8 is provided with a slot 81 with a wedge-shaped surface, and the handle 4 is provided with a button 7. The button is in close contact with the wedge-shaped surface through the wedge block 71. Therefore, pressing the button 7 will make the wedge block 71 slide along the wedge-shaped surface, which can overcome the elastic force of the latch spring 82 to drive the latch 8 to retract and disengage from the gear slot 11. Therefore, the button 7 is actually a manual unlocking component of the latch 8.

[0035] The front end of the suction tube 3 is provided with a telescopic cleaning head 32. In this embodiment, a cleaning brush is selected as the cleaning head. The rear end of the suction tube is detachably inserted into the suction port 21, which can extend the suction distance of the handheld vacuum cleaner and facilitate vacuuming in confined spaces.

[0036] The outer wall of the vacuum tube 3 is provided with a reinforcing rib 31, which is designed to extend axially. Correspondingly, a slot 12 designed axially is provided on the outer surface of the main unit 1. The slot is a single-opening slot, that is, its opening faces the front end. Therefore, the vacuum tube 3 can be detachably attached to the outer surface of the main unit 1 by sliding the reinforcing rib 31 into the slot 12.

[0037] Thus, due to the independent configuration of the suction tube 3, the handheld vacuum cleaner can be put into use simply by detachably inserting the end of the suction tube into the suction port 21 and then rotating the handle 4 outward relative to the main unit 1 to unfold it to various usage angles. Alternatively, the suction tube 3 can be removed from the suction port 21 and detachably slidably inserted into the slot 12 on the outer surface of the main unit 1 by the insertion rib 31 on the outer tube wall, so that the suction tube 3 is just attached to the outer surface of the main unit 1. Then, the handle 4 can be rotated inward relative to the main unit 1 and folded onto the suction tube 3, and the handheld vacuum cleaner can be put into storage.

[0038] Obviously, since the suction pipe 3 is connected or disconnected from the suction port 21 on the dust bin 2 by plugging, it has lower requirements for sealing performance compared with the traditional rotating and folding structure. Therefore, it can prevent air leakage during use, thus greatly ensuring the suction effect of the product.

[0039] In addition, when the vacuum tube 3 is removed and attached to the outer surface of the main unit 1, it can be covered by the folded handle 4. This structure can better prevent the vacuum tube 3 from accidentally touching and soiling the user when storing it.

[0040] 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.
