Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to a handheld vacuum cleaner. Background Technology

[0002] A vacuum cleaner is a cleaning appliance that uses a motor to drive blades to rotate at high speed, creating negative air pressure inside a sealed housing. This draws dust and debris into a dust collection device and then exhausts the filtered air at extremely high speed.

[0003] Traditional handheld vacuum cleaners use a detachable dust cup structure, which allows you to empty the dust by removing the dust cup from the main unit of the vacuum cleaner.

[0004] To clean the dust cup, handheld vacuum cleaners require frequent disassembly and reassembly of the dust cup, which reduces the overall sealing of the vacuum cleaner. Furthermore, modular vacuum cleaners have low structural strength, and the dust cup disassembly and reassembly process can easily damage the vacuum cleaner, failing to effectively protect the filter components. Utility Model Content

[0005] The purpose of this utility model is to provide a handheld vacuum cleaner to solve the problems of low body strength and ineffective protection of filter components caused by the assembled structure of existing handheld vacuum cleaners.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a handheld vacuum cleaner, comprising:

[0007] Vacuum cleaner main unit;

[0008] The dust cup cover is rotatably mounted on the vacuum cleaner main unit;

[0009] The dust collection cover is rotatably mounted on the dust cup cover plate;

[0010] The dust cup cover has a first locking groove at its end, the vacuum cleaner main unit has a first locking tongue corresponding to the first locking groove, and a first torsion spring is sleeved on the rotating shaft of the dust collection cover.

[0011] As a further description of the above technical solution:

[0012] The vacuum cleaner main unit is equipped with a connector, which is detachably mounted on the vacuum cleaner main unit. The dust cup cover is rotatably mounted on the connector, and a second torsion spring is sleeved on the rotating shaft of the dust cup cover.

[0013] As a further description of the above technical solution:

[0014] The vacuum cleaner main unit has two parallel hanging plates on its surface. The cross-section of the hanging plates is "L" shaped. The connecting seat has a hanging groove that matches the shape of the hanging plates. The vacuum cleaner main unit has a second locking plate that is elastically connected to the vacuum cleaner main unit. The end of the second locking plate has a second hook. The connecting seat has a second locking groove that corresponds to the position of the second hook.

[0015] As a further description of the above technical solution:

[0016] The cross-section of the vacuum cleaner's main unit is elliptical.

[0017] As a further description of the above technical solution:

[0018] The vacuum cleaner has a tilted handle at one end.

[0019] As a further description of the above technical solution:

[0020] The first locking tongue is rotatably mounted on the vacuum cleaner main unit. A first spring is provided on the back of the first locking tongue, and a first hook is provided at the bottom of the first locking tongue. The control board is slidably connected to the vacuum cleaner main unit. A connector is provided on the control board. The connector passes through the waist-shaped hole on the vacuum cleaner main unit housing. A linkage rod is provided on the connector. The end of the linkage rod contacts the first locking tongue.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, the vacuum cleaner adopts an integral structure, which can realize the emptying of the dust cup through a large-area opening dust cup cover or a small-area opening dust emptying cover, effectively ensuring the body strength of the vacuum cleaner main unit, effectively protecting the filter components inside the body, and improving the reliability of the vacuum cleaner.

[0023] 2. In this invention, when the amount of dust in the dust cup is small, the dust emptying cover can be rotated open to allow dust to be emptied through the emptying hole on the dust cup cover. When the dust emptying cover is open, a self-closing structure is achieved through the first torsion spring on its rotating shaft to prevent dust leakage. When the amount of dust in the dust cup is large, the first locking tongue releases the lock on the dust cup cover, and the entire dust cup cover is rotated open to achieve quick dust emptying. The vacuum cleaner can flexibly adjust the dust emptying method according to the amount of dust collected, making it convenient to use.

[0024] 3. In this utility model, the dust cup cover is designed to be detachable from the vacuum cleaner main unit via a detachable connector, thereby exposing the filter components on the vacuum cleaner main unit for easy inspection and maintenance.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1

[0038] Please see Figure 1-8 This utility model provides a technical solution: a handheld vacuum cleaner, comprising:

[0039] Vacuum cleaner main unit 1;

[0040] Dust cup cover 2, which is rotatably mounted on the vacuum cleaner main unit 1;

[0041] The dust collection cover 3 is rotatably mounted on the dust cup cover plate 2;

[0042] The dust cup cover 2 has a first fastening groove 21 at its end, and the vacuum cleaner main unit 1 has a first locking tongue 11 corresponding to the first fastening groove 21. A first torsion spring is sleeved on the rotating shaft of the dust collection cover 3. The two legs of the first torsion spring contact the dust collection cover 3 and the dust cup cover 2 respectively, realizing the self-closing structure of the dust collection cover 3.

[0043] The vacuum cleaner main unit 1 has an inclined handle 5 at one end. The handle 5 is not on the same line as the vacuum cleaner main unit 1, which facilitates operation and further prevents the vacuum cleaner main unit 1 from rolling when placed.

[0044] Working principle: When the amount of dust in the dust cup is small, the dust emptying cover 3 can be rotated open, allowing dust to be emptied through the dust emptying hole on the dust cup cover plate 2. When the dust emptying cover 3 is open, a self-closing structure is achieved through the first torsion spring on its rotating shaft to prevent dust leakage. When the amount of dust in the dust cup is large, the first locking tongue 11 releases the lock on the dust cup cover plate 2, allowing the entire dust cup cover plate 2 to be rotated open for quick dust emptying. The vacuum cleaner can flexibly adjust the dust emptying method according to the amount of dust collected, making it convenient to use.

[0045] The vacuum cleaner adopts an integrated structure, and the dust cup can be emptied through the large-area opening dust cup cover 2 or the small-area opening dust emptying cover 3, which effectively ensures the body strength of the vacuum cleaner main unit 1, effectively protects the filter components inside the body, and improves the reliability of the vacuum cleaner.

[0046] Example 2

[0047] This embodiment further improves upon the above embodiment by providing the following technical solution: A connecting seat 4 is provided on the vacuum cleaner main unit 1. The connecting seat 4 is detachably mounted on the vacuum cleaner main unit 1. The dust cup cover 2 is rotatably mounted on the connecting seat 4. A second torsion spring 22 is sleeved on the rotating shaft of the dust cup cover 2. The two legs of the second torsion spring 22 respectively contact the connecting seat 4 and the dust cup cover 2, achieving a self-closing structure for the dust cup cover 2.

[0048] Example 3

[0049] Based on the above embodiments, this embodiment further improves upon the following technical solutions: Two parallel hanging plates 12 are provided on the surface of the vacuum cleaner main unit 1. The cross-section of the hanging plates 12 is "L"-shaped. The connecting seat 4 is provided with a hanging groove 41 that matches the shape of the hanging plates 12. A second locking plate 13 is provided on the vacuum cleaner main unit 1. The second locking plate 13 is elastically connected to the vacuum cleaner main unit 1. A second hook portion 131 is provided at the end of the second locking plate 13. A second fastening groove 42 corresponding to the position of the second hook portion 131 is provided on the connecting seat 4.

[0050] The dust cup cover 2 is detachable from the vacuum cleaner main unit 1 via a detachable connector 4, thereby exposing the filter components on the vacuum cleaner main unit 1 for easy inspection and maintenance. The second locking plate 13 for unlocking the connector 4 is located on an infrequently seen surface of the vacuum cleaner and does not extend beyond the surface of the vacuum cleaner housing to prevent accidental activation.

[0051] When disassembling the dust cup cover 2, first rotate to open the dust cup cover 2, then press the second locking plate 13. The second hook part 131 of the second locking plate 13 moves upward and disengages from the second fastening groove 42, releasing the lock of the connecting seat 4. Then it can be slid out horizontally. During the extraction process, the second locking plate 13 disengages from the hanging groove 41 on the connecting seat 4.

[0052] Example 4

[0053] Based on the above embodiments, this embodiment further improves upon the following technical solution: the cross-section of the vacuum cleaner main unit 1 is elliptical, which effectively prevents the vacuum cleaner main unit 1 from rolling when placed and avoids collision damage.

[0054] Example 5

[0055] Based on the above embodiments, this embodiment further improves upon the following technical solutions: the first locking tongue 11 is rotatably mounted on the vacuum cleaner main unit 1, a first spring 111 is provided on the back of the first locking tongue 11, a first hook is provided at the bottom of the first locking tongue 11, the control plate 6 is slidably connected to the vacuum cleaner main unit 1, the control plate 6 is provided with a connector, the connector passes through the waist-shaped hole on the housing of the vacuum cleaner main unit 1, a linkage rod 61 is provided on the connector, and the end of the linkage rod 61 contacts the first locking tongue 11.

[0056] When the dust cup cover 2 is opened, pushing the control plate 6 causes the linkage rod 61 to move and press the first locking tongue 11. The upper end of the first locking tongue 11 rotates away from the handle 5, while the lower end rotates towards the handle 5. The first hook at the lower end of the first locking tongue 11 retracts and disengages from the first engaging groove 21 at the end of the dust cup cover 2. At this time, the dust cup cover 2 can be rotated open to empty the dust. After emptying the dust, closing the dust cup cover 2 causes the first locking tongue 11 to reset under the elastic force of the first spring 111 on the back, locking the dust cup cover 2. The control plate 6 also resets accordingly.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
