[0023] Reference Figure 1-4 This is an embodiment of the utility model, which discloses a household vacuum cleaner with a folding function, the vacuum cleaner comprises a head assembly 1 and a suction head assembly 2, a rod body 3 is arranged between the head assembly 1 and the suction head assembly 2, specifically, the head assembly 1 comprises a head, a dust cup, a filter and other structures, the connection and working principle of each structure are also disclosed in the prior art, and will not be repeated here;

[0024] It should be further explained that, in this embodiment, the rod body 3 includes an upper rod 31 fixed to the head assembly 1, a folding rod 32 rotatably connected to the lower end of the upper rod 31, and a lower rod 33 rotatably connected to the lower end of the folding rod 32, and the lower rod 33 is rotatably connected to the suction head assembly 2;

[0025] It should be noted that, in this embodiment, the upper rod 31 and the lower rod 33 are both connected to the folding rod 32 via hinges.

[0026] An angle locking structure 4 is provided between the upper rod 31 and the lower rod 33 and the folding rod 32. That is, in this embodiment, the traditional rod body 3 is designed as a three-section structure to realize the folding of the entire rod body 3, and it can be fixed by the angle locking structure 4. Such a design structure can realize the overall folding and storage function. Secondly, compared with the traditional solution in which the suction head assembly 2 is used for support, the folding rod 32 is used in this solution to support the weight of the entire vacuum cleaner, which can reduce the force on the suction head assembly 2.

[0027] In some embodiments, suction pipes are fixed inside the upper rod 31 and the lower rod 33 in the utility model. Of course, the suction pipe inside the upper rod 31 is connected to the dust cup, and the suction pipe inside the lower rod 33 is connected to the suction head assembly 2. A bellows 34 is fixed inside the folding rod 32. Both ends of the bellows 34 extend outward and are fixedly connected to the two suction pipes respectively. In this embodiment, the bellows 34's own deformability is used to support the length and angle changes of the folding rod 32 and the lower rod 33 when they are rotated and folded. In addition, this vacuum pipeline is composed of two suction pipes and the bellows 34, so as to guide the dust and debris sucked into the suction head assembly 2 into the dust cup for collection.

[0028] Furthermore, in the present embodiment, the rotation between the upper rod 31 and the folding rod 32 is taken as an example. Of course, those skilled in the art know that the lower rod 33 and the folding rod 32 should also have the same connection and operating principle. Specifically, the angle locking structure 4 in the present embodiment includes a locking rod 41 rotated on the upper rod 31, and two positioning holes 42 are provided on the end surface of the locking rod 41, and a locking member engaged with the positioning holes 42 is provided on the end surface of the folding rod 32. That is to say, in the present embodiment, the locking member is used to connect the two positioning holes 42, and the two positioning holes 42 are used to adapt to the positioning in the folding and unfolding position after rotation. It should be noted that in the present embodiment, the folding rod 32 and the upper rod 31 rotate ninety degrees, and the lower rod 33 and the folding rod 32 also rotate ninety degrees.

[0029] On the basis of the above-mentioned embodiment, the locking member in this embodiment includes a sleeve 43 embedded in the end face of the folding rod 32, and a positioning rod 45 is movably inserted into the inner side of the sleeve 43 through a spring 44.

When unlocking, the guide column 47 is pressed downward first, and the guide column 47 drives the positioning rod 45 to move downward and separate from the positioning hole 42. At the same time, since the guide column 47 slides to the inside of the guide slot 46 at this time, the entire locking rod 41 will move under the guidance of the guide column 47 until it moves to the other positioning hole 42, and the pressure on the guide column 47 is released. The positioning rod 45 moves upward under the push of the spring 44 and engages with the current positioning hole 42 to complete the folding and fixing operation.

[0031] In some embodiments, at least one support portion 35 is fixedly installed on the side of the folding rod 32 in the utility model through fasteners, and the support portion 35 is configured as a rubber block, and the fastener is preferably configured as a bolt. Furthermore, in this embodiment, two support portions 35 are arranged at intervals, and the bottom of the folding rod 32 is supported by the support portion 35 to improve the force stability of the folding rod 32.
