Description

Technical Field

[0001] The invention belongs to the technical field of vacuum cleaners, and in particular relates to a multi-purpose handy vacuum cleaner with replaceable multiple accessories. Background Art

[0002] Handheld vacuum cleaners use electric exhaust fans to generate suction and negative pressure, sucking in dust and filtering it through dust bags before discharging it, thereby achieving the cleaning function. It generally includes a series commutator motor, a centrifugal fan, a dust filter (bag) and dust collection accessories.

[0003] The functions of handheld vacuum cleaners currently on the market mainly focus on two basic applications: vacuuming and blowing, which to a certain extent meet the basic needs of daily household cleaning. However, with the improvement of quality of life and the diversification of consumer demand, users' expectations for the functions of handheld vacuum cleaners are no longer limited to the traditional cleaning scope, but they expect them to have more practical functions to adapt to more different usage scenarios, and to achieve more extensive functional expansion by replacing different brush head components. However, existing vacuum cleaners cannot meet users' usage needs. Summary of the invention

[0004] In view of this, the present invention proposes a multi-purpose hand-held vacuum cleaner with replaceable multiple accessories in order to solve the problem that current vacuum cleaners mainly focus on two basic applications, dust collection and blowing, and cannot meet customer needs and adapt to more scenarios.

[0005] In order to achieve the above-mentioned object, the present invention adopts the following technical solution: a multi-purpose hand-held vacuum cleaner with replaceable multiple accessories, comprising:

[0006] A vacuum cleaner body, comprising a cyclone motor and a battery pack, wherein the cyclone motor and the battery pack are both located in the vacuum cleaner housing;

[0007] A fixing seat, in which a conductive sheet is arranged;

[0008] and a brush head transmission assembly, which includes a housing, a transmission motor and a gear box, the accessories are detachably connected to the brush head transmission assembly, and the conductive pins are located in the housing.

[0009] As a further description of the above technical solution:

[0010] The vacuum cleaner shell is provided with a plurality of card slots, and the air blowing cover is provided with a plurality of card blocks, and the card blocks are correspondingly carded in the card slots.

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

[0012] The gear box is provided with a connecting groove, and the rotating shaft passes through the connecting groove and is connected to the gear box.

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

[0014] The dust cup assembly is connected to the vacuum cleaner body.

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

[0016] The fixing seat is connected to the vacuum cleaner body, and the conductive pin is electrically connected to the conductive sheet.

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

[0018] The gear box comprises a driving gear and a driven gear, the transmission motor is connected to the driving gear, the driven gear and the driving gear are meshed with each other, and the rotating shaft is connected to the driven gear.

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

[0020] The transmission motor is electrically connected to the conductive pin.

[0021] As a further description of the above technical solution:

[0022] A small combination brush is detachably connected to the dust cup assembly.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] 1. In the present invention, a fixing seat is provided on the vacuum cleaner body, and a conductive sheet is provided on the fixing seat. When the accessory needs to be replaced, it is only necessary to install the brush head transmission assembly on the fixing seat on the vacuum cleaner body, and make the conductive sheet inside the fixing seat contact with the conductive pin in the brush head transmission assembly, and install the accessory on the brush head transmission assembly, so that the conductive pin is connected with the conductive sheet, and the switch button of the vacuum cleaner body is pressed. The cyclone motor of the vacuum cleaner body is not started, and the transmission motor of the accessory starts to rotate and drive the brush head to start rotating. The switch button can also be used to adjust the speed of the cleaning brush head, so that different brush heads can be replaced for brushing shoes, wiping tables, wiping glasses, brushing dishes and other usage scenarios.

[0025] 2. In the present invention, when the dust cup assembly is used for vacuuming, the cyclone motor of the vacuum cleaner body can be started by the switch button of the host to perform vacuuming. The switch button can also be used to adjust the speed and control the suction force of the vacuum cleaner. When blowing is required, the blowing hood only needs to be installed on the top of the vacuum cleaner body to achieve blowing. This structure has strong applicability. Not only can it be used for blowing or vacuuming, but also different accessories can be installed on the brush head according to needs, so it can be used in multiple scenarios.

[0026] 3. In the present invention, when the conductive pin is in contact with the conductive sheet, a relay is closed to connect the power supply to the transmission motor circuit and disconnect the cyclone motor circuit at the same time; on the contrary, when the conductive pin is not in contact with the conductive sheet, the relay will return to its original state and reconnect the power supply to the cyclone motor circuit, thereby being used to switch the circuit connection when replacing accessories.
