[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] The following is for reference. Figures 1-6 A vertical vacuum cleaner 100 according to an embodiment of the present invention is described.

[0031] like Figure 1 As shown, the upright vacuum cleaner 100 according to an embodiment of the present invention includes: a frame 1, a main unit assembly 2, a floor brush assembly 3, a first telescopic tube 4, and a second telescopic tube 5.

[0032] Specifically, the frame 1 extends vertically; the main unit 2 is mounted on the frame 1 and is movable vertically relative to the frame 1; the floor brush assembly 3 is located at the bottom of the frame 1. The main unit 2 may include a dust cup assembly 21 and a motor assembly. The dust cup assembly 21 includes a dust cup 211, which is connected to the floor brush assembly 3. The motor assembly drives dust, impurities, and air from the outside of the floor brush assembly 3 into the floor brush assembly 3, and then draws them into the dust cup assembly 21. The dust cup assembly 21 separates the dust and impurities from the air. At this time, clean air can be directly discharged or flow through the motor assembly to dissipate heat before being discharged. Meanwhile, impurities and dust remain inside the dust cup assembly 21.

[0033] Furthermore, the first telescopic tube 4 is telescopic, for example, the first telescopic tube 4 is telescopic along its length, and one end of the first telescopic tube 4 (e.g.) Figure 6 The lower end of the first telescopic tube 4 shown is connected to and communicates with the floor brush assembly 3, and the other end of the first telescopic tube 4 (e.g., Figure 6 The upper end of the first telescopic tube 4 shown is movable in the vertical direction relative to the frame 1. For example, the lower end of the first telescopic tube 4 can be connected to the outlet of the airflow chamber of the floor brush assembly 3, and the upper end of the first telescopic tube 4 can be movably disposed on the frame 1 in the vertical direction.

[0034] Furthermore, the second telescopic tube 5 is telescopic, for example, the second telescopic tube is telescopic along its length (e.g. Figure 6 The second telescopic tube 5 (shown in the up-down direction) is retractable, and one end of the second telescopic tube 5 (e.g.) Figure 6 The upper end of the second telescopic tube 5 shown is connected to and communicates with the dust cup 211 of the main unit 2, and the other end of the second telescopic tube 5 (e.g. Figure 6 The lower end of the second telescopic tube 5 shown is movable in the vertical direction relative to the frame 1, and the other end of the second telescopic tube 5 (e.g. Figure 6 The lower end of the second telescopic tube 5 shown in the figure) and the other end of the first telescopic tube 4 (e.g.) Figure 6 The upper end of the first telescopic tube 4 shown is connected and communicated. For example, the lower end of the second telescopic tube 5 can be movably disposed on the frame 1 in the vertical direction, and the lower end of the second telescopic tube 5 is connected to the upper end of the first telescopic tube 4, while the upper end of the second telescopic tube 5 is connected to the dust cup 211 of the dust cup assembly 21.

[0035] Thus, when adjusting the height of the main unit 2 during the use of the upright vacuum cleaner 100, it can be manually pulled or driven by a drive unit to move the main unit 2 upward along the frame 1. At this time, as the main unit 2 moves upward, the second telescopic tube 5 can extend to match the upward movement of the main unit 2, ensuring that the dust cup 211 of the floor brush assembly 3 and the main unit 2 are always connected. When the second telescopic tube 5 extends to the predetermined length, if the main unit 2 continues to move upward, the first telescopic tube 4 can also extend to match the upward movement of the main unit 2. This increases the vertical movement distance of the main unit 2, allowing it to move to the top of the frame 1, so that the upright vacuum cleaner 100 can work like a handheld vacuum cleaner, thereby preventing the main unit 2 from colliding with or interfering with the floor brush assembly 3 or furniture during cleaning.

[0036] It should be noted that, for ease of description, the process of the host component 2 moving upward is described in the order of the second telescopic tube 5 extending first and the first telescopic tube 4 extending later. However, the present invention is not limited to this. There is no restriction on the extension order of the first telescopic tube 4 and the second telescopic tube 5. That is to say, during the process of the host component 2 moving upward, the first telescopic tube 4 can extend first and the second telescopic tube 5 can extend later, or the first telescopic tube 4 and the second telescopic tube 5 can extend simultaneously to cooperate with the upward movement of the host component 2.

[0037] According to an embodiment of the present invention, the upright vacuum cleaner 100 is connected between the dust cup 211 and the floor brush assembly 3 by providing a retractable first telescopic tube 4 and a second telescopic tube 5. This increases the vertical movement distance of the main unit assembly 2, allowing the main unit assembly 2 to move across the entire height range of the frame 1. This facilitates moving the main unit assembly 2 to the top of the frame 1, enabling the upright vacuum cleaner 100 to operate like a handheld vacuum cleaner, making it more convenient to operate and more versatile.

[0038] Furthermore, compared to a design where only the second telescopic tube 5 connected to the main unit 2 is telescopic, the main unit 2 has a smaller range of movement in the vertical direction and cannot move to the top of the frame 1. Therefore, in this embodiment, the upright vacuum cleaner 100 has two telescopic tubes by also making the first telescopic tube 4 connected to the floor brush assembly 3 telescopic. This further increases the vertical movement distance of the main unit 2, enabling it to move to the top of the frame 1 and function like a handheld vacuum cleaner.

[0039] Optionally, the first telescopic tube 4 can be a telescopic flexible tube, and / or the second telescopic tube 5 can also be a telescopic flexible tube. This simplifies the structure of the first and second telescopic tubes and reduces costs. Furthermore, the length of the first telescopic tube is greater than the length of the second telescopic tube, which facilitates increasing the vertical movement distance of the main unit 2, making the structural arrangement of the first and second telescopic tubes more reasonable.

[0040] like Figure 4 As shown, in one embodiment of the present invention, the upright vacuum cleaner 100 may further include: a connecting connector 6, one end of the connecting connector 6 (e.g., Figure 4 The lower end of the connecting joint 6 shown in the figure) and the other end of the first telescopic tube 4 (e.g. Figure 4 The upper end of the first telescopic tube 4 shown in the figure is sealed and connected, and the other end of the connecting joint 6 (e.g.) Figure 4 The upper end of the connecting joint 6 shown in the figure) and the other end of the second telescopic tube 5 (e.g.) Figure 4 The lower end of the second telescopic tube 5 shown in the diagram is sealed. This allows for easy connection between the first telescopic tube 4 and the second telescopic tube 5, ensuring the reliability and sealing performance of the connection between them.

[0041] Furthermore, one end of the connecting connector 6 (e.g.) Figure 4 The lower end of the connecting joint 6 shown in the figure) and the other end of the first telescopic tube 4 (e.g. Figure 4 The upper end of the first telescopic tube 4 shown in the figure is fixedly connected, and the other end of the connecting joint 6 (e.g.) Figure 4 The upper end of the connecting joint 6 shown in the figure) and the other end of the second telescopic tube 5 (e.g.) Figure 4 The lower end of the second telescopic tube 5 shown in the figure is detachably connected. That is to say, the connection between the first telescopic tube 4 and the connecting joint 6 is a fixed and non-detachable connection, while the connection between the second telescopic tube 5 and the connecting joint 6 is a detachable and removable connection. Therefore, the second telescopic tube can be easily disassembled, making it convenient to use the upright vacuum cleaner of this embodiment as a handheld vacuum cleaner, and the operation is more convenient.

[0042] Furthermore, referring to Figure 3 The frame 1 can be formed with vertically extending grooves (such as the first groove 111 and the second groove described below), and the connecting joint 6 is slidably fitted into the grooves. Specifically, the outer peripheral wall of the connecting joint 6 is provided with a horizontally protruding slider 61, which is inserted into the groove and can slide along the groove. In this way, the upper end of the first telescopic tube 4 and the lower end of the second telescopic tube 5 can be slidably fixed to the frame 1 through the connecting joint 6, so that both can slide relative to the frame 1 in the vertical direction, and the structure is compact and simple.

[0043] According to some embodiments of the present invention, such as Figure 3 As shown, the frame 1 may include a first support arm 11 and a second support arm 12, both of which extend in the vertical direction, and the first support arm 11 and the second support arm 12 extend in the width direction of the upright vacuum cleaner 100 (e.g., ...). Figure 3 As shown in the diagram, the components are arranged at intervals in the left and right directions. The main unit 2 can be movably mounted on the first support arm 11 and / or the second support arm 12 in the up and down direction. The first telescopic tube 4 can also be movably mounted on the first support arm 11 and / or the second support arm 12 in the up and down direction. The second telescopic tube 5 can also be movably mounted on the first support arm 11 and / or the second support arm 12 in the up and down direction.

[0044] Furthermore, referring to Figure 3 A first groove 111 extending in the vertical direction can be formed on the first support arm 11, and a second groove (not shown) extending in the vertical direction can be formed on the second support arm 12. The first groove 111 and the second groove are arranged opposite to each other and facing each other. For example, the first support arm 11 and the second support arm 12 are arranged with a left-right interval, and the first support arm 11 is located to the left of the second support arm 12. The right surface of the first support arm 11 has a first groove 111 extending in the vertical direction, and the opening of the first groove 111 faces the second support arm 12. The left surface of the second support arm 12 has a second groove extending in the vertical direction, and the opening of the second groove faces the first support arm 11.

[0045] Furthermore, the main unit 2, the first telescopic tube 4, and / or the second telescopic tube 5 are slidable along the first slide groove 111 and the second slide groove. This simplifies the sliding fit structure between the main unit 2, the first telescopic tube 4, the second telescopic tube 5, and the frame 1, facilitates processing, and makes the relative sliding implementation simpler and more convenient.

[0046] Furthermore, by providing a first sliding groove 111 and a second sliding groove arranged in opposite directions, when the main unit assembly 2, the first telescopic tube 4, and the second telescopic tube 5 are engaged within the first sliding groove 111 and the second sliding groove, the first sliding groove 111 and the second sliding groove can restrict the displacement of the main unit assembly 2, the first telescopic tube 4, and the second telescopic tube 5 in the left and right directions, thereby effectively preventing the main unit assembly 2, the first telescopic tube 4, and the second telescopic tube 5 from slipping out of the first sliding groove 111 and the second sliding groove. In addition, when the main unit assembly 2, the first telescopic tube 4, and the second telescopic tube 5 are engaged within the first sliding groove 111 and the second sliding groove, this engagement structure can further enhance the strength of the frame 1 and improve the stability of the frame 1 structure.

[0047] Optionally, such as Figure 3As shown, the frame 1 may further include a connecting arm 13, which is connected to the top of the first support arm 11 and the second support arm 12. The connecting arm 13, the first support arm 11, and the second support arm 12 are integrally formed, thereby enhancing the overall shape and strength of the frame 1. Furthermore, the handle 8 of the upright vacuum cleaner 100 can be connected to the connecting arm 13, thus facilitating the installation of the handle 8 and making it easier for the user to grip and operate.

[0048] In some examples, refer to Figure 3 The upright vacuum cleaner 100 may further include: a support frame 7, which is a vertically arranged rectangular ring. The outer surfaces of both the left and right sides of the support frame 7 have outwardly protruding guide blocks 71. These guide blocks 71 are slidably fitted into a first groove 111 and a second groove. Specifically, the guide block 71 on the outer surface of the left side of the support frame 7 protrudes towards the first groove 111 and is slidably fitted into it; the guide block 71 on the outer surface of the right side of the support frame 7 protrudes towards the second groove and is slidably fitted into it. The main unit assembly 2 is fixed to the support frame 7. When the support frame 7 slides relative to the frame 1, it can cause the main unit assembly 2 to slide relative to the frame 1. Furthermore, by providing the support frame 7, the stability of the main unit assembly 2 can be improved.

[0049] Furthermore, referring to Figure 3 Multiple guide blocks 71 can be provided on the left side wall of the support frame 7, and these guide blocks 71 can be arranged at intervals in the vertical direction. Simultaneously, multiple guide blocks 71 can also be provided on the right side wall of the support frame 7, and these guide blocks 71 are also arranged at intervals in the vertical direction. This increases the contact area between the support frame 7 and the first and second sliding grooves, improving the stability and reliability of the sliding fit.

[0050] Optionally, the guide block 71 is formed in the shape of a cube or cuboid, and the cross-sections of the first slide groove 111 and the second slide groove are formed in the shape of a square or rectangular cross-section. Of course, the present invention is not limited to this, and the shape of the guide block 71 can also be formed in other shapes, such as trapezoidal, semi-circular, etc., as long as it is adapted to the shape of the first slide groove 111 and the second slide groove.

[0051] In some embodiments of the present invention, the frame 1 is formed with a sliding groove (e.g., the first sliding groove 111 and the second sliding groove mentioned above). The upright vacuum cleaner 100 may further include a support frame 7, on which a protruding guide block 71 is formed. The guide block 71 is slidably engaged in the sliding groove, and the main unit assembly 2 is fixed to the support frame 7. Thus, the main unit assembly 2 can be slidably mounted on the frame 1 in the vertical direction.

[0052] In some embodiments of the present invention, the upright vacuum cleaner 100 may further include a locking member (not shown), which is disposed on the frame 1 and / or the main unit assembly 2. The locking member is switchable between a locked state that locks the main unit assembly 2 onto the frame 1 and a released state that releases the main unit assembly 2 so that it can slide relative to the frame 1. That is, the locking member has a locked state and a released state, and can switch between the two. In the locked state, the locking member can lock the main unit assembly 2 onto the frame 1, at which time the main unit assembly 2 cannot move up and down relative to the frame 1. In the released state, the locking member can release the main unit assembly 2, at which time the main unit assembly 2 can slide relative to the frame 1 in the up and down direction. Thus, by providing a locking member, the main unit assembly 2 can be easily locked at any height position on the frame 1, ensuring that the main unit assembly 2 is stable at any height on the frame 1.
