Description

Technical Field

[0001] This utility model relates to the field of handheld vacuum cleaner technology, specifically to a handheld vacuum cleaner with a replaceable vacuum head. Background Technology

[0002] A handheld vacuum cleaner is a portable cleaning device with a lightweight and wireless design at its core. It generates negative pressure suction through a motor and completes cleaning tasks directly through the handheld unit. Through continuous iteration of technologies such as motors, batteries, and dust-air separation, handheld vacuum cleaners have become a core tool in modern cleaning scenarios.

[0003] Existing handheld vacuum cleaners are only equipped with a single type of vacuum head, which cannot flexibly change to a suitable vacuum head according to different actual application scenarios (such as sofa crevices, carpets, corners, etc.).

[0004] For example, the handheld vacuum cleaner disclosed in patent CN210612012U allows the vacuum head to be detachably mounted on the housing through the cooperation of the first sealing connection part and the second sealing connection part. However, it does not provide a spare vacuum head for replacement. Different cleaning scenarios (such as sofa crevices, carpets, corners, etc.) require different types of vacuum heads to optimize the cleaning effect. If there is no spare vacuum head for replacement, it is difficult for users to quickly adjust the type of vacuum head according to actual needs, resulting in reduced cleaning efficiency.

[0005] Therefore, it is necessary to invent a handheld vacuum cleaner with a replaceable vacuum head to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a handheld vacuum cleaner with replaceable vacuum heads, which solves the problem that only a single type of vacuum head is provided, making it impossible to flexibly change to a suitable vacuum head according to different actual application scenarios (such as sofa crevices, carpets, corners, etc.).

[0007] To achieve the above objectives, this utility model provides the following technical solution: a handheld vacuum cleaner with replaceable vacuum heads, comprising a main housing, the main housing having a hollow internal structure in which a vacuum fan and a dust cup are installed, a first mounting plate is provided on one side of the main housing, a first vacuum head is provided on one side of the first mounting plate, a second vacuum head is provided on one side of the first vacuum head, a second mounting plate is provided at the position of the first and second vacuum heads corresponding to the position of the first mounting plate, a T-shaped slider is provided on one side wall of the second mounting plate, a T-shaped groove is provided on the first mounting plate corresponding to the position of the T-shaped slider, and the shape of the T-shaped groove is adapted to the T-shaped slider, and a fixing component is provided at the top of the connection between the first and second mounting plates.

[0008] Preferably, a battery module is also provided in the hollow area inside the main housing, and the output end of the battery module is connected to the motor input end of the vacuum cleaner fan, and the input end of the battery module is connected to the power switch outside the main housing. The purpose of this design is to provide power support for the vacuum cleaner fan, so that the vacuum cleaner can work without a power cord and achieve portable operation. Users can conveniently control the start and stop of the vacuum cleaner through the power switch.

[0009] Preferably, the dust cup is equipped with a filter cover inside, which is used to filter the dust and air sucked into the dust cup and prevent dust and other impurities from entering the dust collection fan.

[0010] Preferably, a sealing gasket is provided at the connection between the first mounting plate and the second mounting plate, and the sealing gasket is adhered to the wall surface of the first mounting plate. The purpose is to enhance the sealing of the connection between the two mounting plates and prevent dust, air and other substances from leaking from the connection.

[0011] Preferably, the fixing component includes a bearing seat, which is installed on the outer wall of the first mounting plate by screws. The bearing seat is provided with a pin, and a fixing plate is hinged to the pin. This design allows the fixing plate to rotate around the pin, making it convenient for the user to operate the fixing plate.

[0012] Preferably, a limiting groove is provided at one end of the fixing plate, and a limiting rod provided on the outer wall of the second mounting plate can be adapted to the limiting groove. When the fixing plate is rotated to a certain position, the limiting rod can be inserted into the limiting groove to achieve the initial fixing of the first mounting plate and the second mounting plate.

[0013] Preferably, a fixing nut is threaded onto the limiting rod, and the inner thread of the fixing nut engages with the outer thread of the limiting rod. When the limiting rod is engaged in the limiting groove, tightening the fixing nut can further reinforce the connection between the first mounting plate and the second mounting plate.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model features a T-shaped groove on the first mounting plate and matching T-shaped sliders on the second mounting plates corresponding to the first and second vacuum heads. This allows the first and second vacuum heads to connect or separate from the main housing through simple sliding motions. This structural design is simple and intuitive, allowing users to easily assemble and disassemble the vacuum heads without complicated tools or professional skills, greatly improving ease of use. Furthermore, the fixing components reinforce the connection between the first and second mounting plates, ensuring the stability of the first or second vacuum head during use.

[0016] 2. The No. 1 and No. 2 vacuum heads in this utility model adopt a detachable installation structure, allowing users to flexibly select and replace the No. 1 or No. 2 vacuum head according to different cleaning needs. For example, for cleaning narrow gaps, the No. 2 vacuum head with a thinner and narrower suction port can be selected; while for cleaning large areas of the floor, the No. 1 vacuum head with stronger suction and a larger suction area can be selected, thereby improving the applicability and cleaning efficiency of the handheld vacuum cleaner and meeting the needs of diverse cleaning scenarios.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-6The handheld vacuum cleaner with a replaceable vacuum head shown includes a main housing 1. The main housing 1 has a hollow structure inside, in which a vacuum fan 101 and a dust cup 102 are installed. A filter cover 103 is provided inside the dust cup 102. A battery module is also provided in the hollow area inside the main housing 1. The output end of the battery module is connected to the motor input end of the vacuum fan 101, and the input end of the battery module is connected to a switch on the outside of the main housing 1.

[0027] In this embodiment, the battery module provides power to the motor in the vacuum cleaner 101, enabling the vacuum cleaner 101 to operate normally. The switch on the outside of the main housing 1 controls the circuit between the battery module and the motor, thereby controlling the start and stop of the vacuum cleaner 101 for user convenience. After the vacuum cleaner 101 is started, it generates suction to suck dust and other debris into the dust cup 102. The filter cover 103 can filter the sucked-in air to prevent dust and other debris from entering the vacuum cleaner 101, protecting the vacuum cleaner 101 to work normally, while realizing the vacuuming function.

[0028] The main housing 1 has a first mounting plate 2 on one side. A first suction head 3 is provided on one side of the first mounting plate 2, and a second suction head 4 is provided on one side of the first suction head 3. A sealing gasket is provided at the connection between the first mounting plate 2 and the second mounting plate 5, and the sealing gasket is adhered to the wall surface of the first mounting plate 2. A second mounting plate 5 is provided at the position of the first suction head 3 and the second suction head 4 corresponding to the position of the first mounting plate 2. A T-shaped slider 6 is provided on one side wall surface of the second mounting plate 5. A T-shaped groove 7 is provided at the position of the first mounting plate 2 corresponding to the position of the T-shaped slider 6, and the shape of the T-shaped groove 7 is adapted to the T-shaped slider 6.

[0029] In this embodiment, mounting plate 2 provides the mounting base for vacuum head 3 and vacuum head 4. Vacuum head 3 or vacuum head 4 is connected to mounting plate 2 via mounting plate 5, thus enabling the installation of vacuum head 3 or vacuum head 4. The sealing gasket ensures the sealing of the connection between mounting plate 2 and mounting plate 5, preventing dust and other debris from leaking out and improving the vacuuming effect. Furthermore, the cooperation between the T-shaped slider 6 and the T-shaped groove 7 allows mounting plate 5 to slide on mounting plate 2, facilitating the installation, removal, and replacement of vacuum head 3 or vacuum head 4.

[0030] A fixing component 8 is provided at the top of the connection between mounting plate 2 and mounting plate 5. The fixing component 8 includes a bearing seat 801, which is installed on the outer wall of mounting plate 2 by screws. A shaft pin 802 is provided on the bearing seat 801, and a fixing plate 803 is hinged to the shaft pin 802. A limit groove 804 is provided at one end of the fixing plate 803. A limit rod 9 provided on the outer wall of mounting plate 5 can be adapted to the limit groove 804. A fixing nut 10 is threadedly connected to the limit rod 9, and the inner thread of the fixing nut 10 is engaged with the outer thread of the limit rod 9.

[0031] In this embodiment, the fixing component 8 is used to fix the connection between the first mounting plate 2 and the second mounting plate 5. After the second mounting plate 5 and the first mounting plate 2 are connected in place, the fixing plate 803 is rotated around the shaft pin 802 so that the limiting rod 9 on the outer wall of the second mounting plate 5 is inserted into the limiting groove 804 at one end of the fixing plate 803. Then, the fixing nut 10 is tightened. The fixing plate 803 is fixed by the threaded engagement between the fixing nut 10 and the limiting rod 9, thereby firmly connecting the first mounting plate 2 and the second mounting plate 5, preventing the first vacuum head 3 or the second vacuum head 4 from loosening during use, and ensuring the stability and reliability of the vacuum cleaner.

[0032] Working principle of this utility model:

[0033] Refer to the instruction manual appendix Figure 1-6 When using this utility model, when disassembling the current vacuum head (taking the disassembly of vacuum head 3 as an example; if the disassembly of vacuum head 2 is required, the operation is the same), firstly, turn the fixing nut 10 counterclockwise so that it moves outward along the thread of the limiting rod 9 until the fixing nut 10 is not fastened to the fixing plate 803 and is not released from the limiting rod 9. Then, manually rotate the fixing plate 803 upward around the shaft pin 802 so that the limiting rod 9 on the outer wall of the second mounting plate 5 is dislodged from the limiting groove 804 at one end of the fixing plate 803, thereby releasing the fixing component 8 from fixing the first mounting plate 2 and the second mounting plate 5. Then, hold the first vacuum head 3 and push the first vacuum head 3 upward in the opposite direction to the installation direction. The T-shaped slider 6 will slide in the T-shaped groove 7 until the T-shaped slider 6 slides out completely from the T-shaped groove 7. At this time, the first vacuum head 3, together with the second mounting plate 5 on it, is separated from the first mounting plate 2, thus completing the disassembly of the first vacuum head 3.

[0034] When installing a new vacuum head (taking the installation of vacuum head 4 as an example; the operation is the same if vacuum head 3 is to be installed), first hold vacuum head 4 and align the T-shaped slider 6 on the corresponding mounting plate 5 with the T-shaped groove 7 on the mounting plate 2. Push vacuum head 4 downwards along the installation direction so that the T-shaped slider 6 slides into the T-shaped groove 7, and continue pushing until mounting plate 5 and mounting plate 2 are tightly fitted together. Then, rotate the fixing plate 803 downwards around the shaft pin 802 so that the limiting rod 9 on the outer wall of mounting plate 5 is engaged in the limiting groove 804 at one end of the fixing plate 803. Finally, turn the fixing nut 10 clockwise so that it moves inwards along the thread of the limiting rod 9 until the fixing nut 10 is tightly fitted with the fixing plate 803, thus firmly fixing the fixing plate 803. This completes the connection and fixing of mounting plate 2 and mounting plate 5, ensuring that vacuum head 4 is firmly installed and preventing loosening during use.

[0035] By following the steps above, you can complete the replacement of vacuum head 3 (number one) with vacuum head 4 (number two).
