[0027] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0028] Reference Figure 1-4 In one embodiment of the present invention, a portable toolbox vacuum cleaner 10 includes a housing 11 and a head assembly 12 disposed on the housing 11. The head assembly 12 includes a power assembly that generates a vacuum suction force, driving airflow to enter from an air inlet on the housing 11, and clean airflow filtered by a filter is discharged from an exhaust port, and dust is retained inside the housing 11. The upper cover of the head assembly 12 is roughly quadrilateral, and a first storage portion 13 for storing a first accessory 20 is provided on the outer surface of the upper cover. In order to save storage space and maintain overall uniformity and beauty, the first storage portion 13 is disposed at a corner of the upper cover of the toolbox vacuum cleaner. Of course, it can also be disposed at other positions on the upper cover of the head assembly according to the specific structure of the toolbox vacuum cleaner 10.

[0029] The portable vacuum cleaner of this embodiment is a toolbox vacuum cleaner powered by a battery pack. Of course, in other embodiments, it can also be other upright or barrel vacuum cleaners powered by other means such as AC power, as long as all accessories are integrated into the vacuum cleaner.

[0030] Specifically, a second storage portion 14 is provided on the outer surface of the first storage portion 13. The second storage portion 14 has a storage cavity 15 that can completely accommodate the second accessory 30. In this embodiment, the storage cavity 15 is vertically downward from the outer surface of the second storage portion 14. A locking mechanism for fixing the mouthpiece 32 is provided in the storage cavity 15. One end of the second accessory 30 is a connecting pipe portion 31, and the other end is a mouthpiece 32 of the same size. Since the mouthpieces 32 of the second accessory 30 are configured to have the same size, when storing second accessories 30 of different models and sizes, although the connecting pipe portions 31 of the second accessories 30 have different pipe diameters, the mouthpieces 32 of the same size can be locked by the locking mechanism, so as to achieve compatible storage of second accessories 30 with different connecting pipe diameters.

[0031] In this embodiment, the second receiving portion 14 is a slot 16 formed on the outer surface of the first receiving portion 13. The second accessory 30 shrinks from the connecting tube portion 31 to the suction port portion 32. The diameter of the connecting tube portion 31 is larger than the outer diameter of the suction port portion 32. The diameter of the slot 16 is larger than the diameter of the thickest connecting tube portion in the second accessory 30 that can be matched therewith.

[0032] Reference Figure 5-6 In this embodiment, the first accessory 20 is a car suction, and the second accessory 30 is a flat suction. For example, the aperture of the slot 16 is set to 38mm, the diameter of the connecting pipe of one size of the flat suction is set to 37.5mm, and the diameter of the connecting pipe of another size of the flat suction is set to 35.5mm. When a portable toolbox vacuum cleaner with flat suction parts of different sizes is developed and designed at the same time, since the suction mouth of the flat suction has the same size, both flat suctions can be stored inside the vacuum cleaner, realizing the function of compatible storage. There is no need to match different parts of the whole machine for different accessories, saving manufacturing costs and avoiding unnecessary waste in the development process and mold design. Of course, the aperture of the slot 16 can also be set to other sizes or structures, and it is only necessary to set the inner diameter of the storage cavity 15 to be larger than the diameter of the largest connecting pipe among the multiple second accessories 30.

[0033] Reference Figure 7-9 The locking mechanism in this embodiment includes a snap button 17 disposed on the inner wall of the storage cavity 15. The snap button 17 is integrally disposed with the inner wall of the storage cavity 15, and the snap button 17 has a free end that can rotate relative to the tube axis. When the second accessory 30 is stored in the storage cavity, the snap button 17 is pressed against the suction opening 32. The suction opening 32 of the flat suction and the snap button 17 are fitted with interference to ensure that there is a certain insertion and extraction force between the two. The same wall thickness and elastic deformation of the same series of automobile suction bodies with different calibers enable the flat suctions with different calibers to be effectively positioned.

[0034] The locking mechanism also includes at least two protrusions 18 provided on the inner wall of the storage chamber 15, and the suction opening 32 of the second accessory 30 includes at least two recesses 33. When the second accessory 30 is stored in the storage chamber 15, the protrusions 18 and the recesses 33 cooperate to limit the position. Of course, in addition to using the snap-on structure, other fixing methods such as snaps can also be used to fix the suction opening 32 of the second accessory 30 inside the slot 16. In addition, the fixing device can also include a sensor device to prevent the second accessory 30 from being lost. When the second accessory 30 is not inserted into the second storage portion 14 after use, the sensor device sends an alarm signal to the controller of the vacuum cleaner, and the sound and light alarm device of the vacuum cleaner can send sound and light alarm signals to remind the user to store the second accessory 30 in time.

[0035] The storage cavity 15 can store second accessories 30 with different suction port diameters. The second storage portion 14 is a slot 16 vertically opened on the outer surface of the first storage portion 13, so it is more convenient for users to take and put. Of course, the second storage portion 14 can also extend from the first storage portion 13 in a horizontal direction or in a direction at a set angle to the horizontal direction, that is, the second accessory 30 can be inserted and stored in the second storage portion 14 at any angle.

[0036] Reference Figure 10-11 When the user needs to use the car suction or flat suction piece for work, the user needs to first take the car suction or flat suction piece out of its storage cavity. When the work is completed, the flat suction piece is first inserted into the slot 16, and then the car suction piece is inserted into the first storage portion 13 and fixed. Figure 1 When the first accessory 20 is in the storage state, that is, the first accessory 20 is stored in the first storage portion 13, the slot 16 is covered by the first accessory 20. When both the first accessory 20 and the second accessory 30 are in the storage state, that is, the first accessory 20 is stored in the first storage portion 13, and the second accessory 30 is stored in the second storage portion 14, the second accessory 30 is covered by the first accessory 20. Therefore, it not only plays the role of storing all accessories in the vacuum cleaner to save storage space, but also plays the role of blocking dust from entering the slot 16 because the suction port of the first accessory 20 covers the mouth of the slot 16.

[0037] The first storage portion 13 includes a protrusion 131 for fixing the end of the tube body 21 of the first accessory 20, a first cavity 132 for accommodating the tube body 21, and a second cavity 133 extending upward from the first cavity 132 for accommodating the suction mouth 22 of the first accessory 20. When the first accessory 20 is stored in the first storage portion 13, one end of the tube body 21 of the first accessory 20 is sleeved on the protrusion 131, and the triangular suction mouth 22 of the first accessory 20 is accommodated in the second cavity 133. The outer surface of the first accessory 20 matches the outer surface of the head assembly 12 to form a consistent regular surface, which neither destroys the aesthetic visual effect of the overall shape nor saves storage space.

[0038] The present invention provides a second storage portion 14 on the outer surface of the first storage portion 13 that can completely accommodate the second accessory 30, so that all accessories can be stored inside the vacuum cleaner. Since the suction openings 32 of the second accessories 30 are configured to have the same size, the suction openings 32 are locked by a locking mechanism during storage to achieve compatible storage of second accessories with different connection pipe diameters. In addition, the structure and position of the first accessory match the shape of the whole machine and are covered on the second accessory, which does not destroy the overall shape, saves storage space, and also plays a role in covering dust.
