Detailed Implementation

[0024] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only for illustrating the basic concept of this utility model. Unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0025] Please see Figure 1-5This embodiment discloses a dust collection device for a household vacuum cleaner, comprising: a dust collection box 1, which is removably mounted on the vacuum cleaner housing 2; and a lifting mechanism 3, used to lift the dust collection box 1 after it is inserted into place, so that the opening 1a of the dust collection box 1 is sealed and connected with the dust outlet (not shown in the figure) on the vacuum cleaner housing 2. Here, the vacuum cleaner housing 2 refers to the outer shell of the vacuum cleaner, also known as the vacuum cleaner's casing. In the structure of the household vacuum cleaner, the sealing connection between the opening 1a of the dust collection box 1 and the dust outlet of the vacuum cleaner forms a relatively closed cavity structure to ensure sufficient negative pressure during use. The dust separated by the dust separation chamber of the household vacuum cleaner falls into the dust collection box 1 through the dust outlet. The structural design of the dust separation chamber and the dust outlet of the household vacuum cleaner is prior art and will not be described in detail here. The lifting mechanism 3 can be a manual lifting structure, such as a manually driven screw and nut lifting structure; it can also be an electric lifting structure, such as an electric push rod lifting structure; or it can be a pneumatic cylinder or hydraulic cylinder lifting structure, etc., without limitation. The dust collection device for household vacuum cleaners provided above is easy to use and helps reduce air leakage, thereby improving the service life and reliability of the device. Specifically, in this dust collection device, the dust collection box 1 is removable, making it easy to install and remove, and convenient to use; because the dust collection box 1 is lifted after being inserted into place by the additional lifting mechanism 3, the dust collection box 1 does not need to be tightly fitted with the vacuum cleaner housing 2 during the insertion and removal process. In this way, the sealing surface between the dust collection box 1 and the vacuum cleaner housing 2 will not be damaged during the installation and removal process, which can effectively reduce air leakage and thus improve the service life and reliability of the device. In addition, the lifting mechanism 3 can effectively ensure that the opening 1a of the dust collection box 1 is sealed and connected with the dust outlet on the vacuum cleaner housing 2, which is reliable and helps to ensure the reliability of the seal, and can also improve the reliability of the household vacuum cleaner.

[0026] In this embodiment, the vacuum cleaner housing 2 has a horizontally arranged, end-opening dust collection box mounting cavity 201. The dust outlet (not shown in the figure) is located at the top of the dust collection box mounting cavity 201, and the dust collection box 1 is slidably disposed in the dust collection box mounting cavity 201. During insertion and removal, the dust collection box 1 rests on the bottom surface of the dust collection box mounting cavity 201, with the side walls on both sides of the dust collection box mounting cavity 201 forming a guide for the dust collection box 1. By using an end-opening, horizontally arranged dust collection box mounting cavity 201, the stability of the dust collection box 1 insertion and removal process is ensured.

[0027] In this embodiment, the lifting mechanism 3 is integrated into the bottom of the dust collection box 1; by integrating the lifting mechanism 3 into the bottom of the dust collection box 1, it is beneficial to simplify the structural design of the vacuum cleaner housing 2 and simplify the structure; it is also beneficial to assemble the lifting mechanism 3, thereby reducing manufacturing costs.

[0028] In this embodiment, the bottom of the powder collection box 1 is provided with an upwardly recessed receiving groove 101, and the lifting mechanism 3 is arranged in the receiving groove 101. The lifting mechanism 3 includes a support block 301 that can be driven to rise and fall vertically and a driving structure for driving the support block 301 to rise and fall. The support block 301 is used to support the bottom surface of the powder collection box mounting cavity 201 to lift the powder collection box 1. By setting the receiving groove 101 at the bottom of the powder collection box 1, the overall vertical space occupied is effectively reduced, which can effectively improve the compactness of the powder collection box 1 mounting structure, thereby ensuring the compactness of the overall structure of the household vacuum cleaner. At the same time, by arranging the lifting mechanism 3 in the receiving groove 101, the bottom surface of the powder collection box 1 can slide directly on the bottom surface of the powder collection box mounting cavity 201, which effectively simplifies the sliding structure design of the powder collection box 1 and also helps to ensure the sliding stability of the powder collection box 1.

[0029] In this embodiment, the driving structure includes a rotating shaft 302 mounted on the powder collection box 1, which can be driven to rotate and locked; an eccentric wheel 303 fixed on the rotating shaft 302; and a fixed base 304 fixed to the bottom of the powder collection box 1. A support block 301 is vertically slidably mounted on the fixed base 304. The rotating shaft 302 is rotatably connected to the fixed base 304, and the eccentric wheel 303 is drively connected to the support block 301 to drive its sliding. Specifically, the fixed base 304 is fixedly connected to the powder collection box 1 by screws or welding. The fixed base 304 has a cylindrical structure, and the support block 301 is slidably mounted inside the inner cylinder of the fixed base 304. The support block 301 has mounting holes that mate with the eccentric wheel 303, and the eccentric wheel 303 is mounted in these mounting holes. In use, the rotating shaft 302 can be rotated manually or electrically to drive the eccentric wheel 303 to rotate, thereby causing the support block 301 to slide in the fixed seat 304. Because the position of the support block 301 relative to the fixed seat 304 changes, and the support block 301, after assembly, supports the bottom of the powder collection box mounting cavity 201, this manifests as the powder collection box 1 being raised or lowered within the powder collection box mounting cavity 201. The lifting mechanism 3 in this structural design is simple and reliable. The eccentric wheel structure used to adjust the height of the powder collection box 1 helps ensure the stability and accuracy of the powder collection box 1. Simultaneously, the powder collection box can be raised simply by rotating the rotating shaft, resulting in high operational efficiency and ease of operation, and facilitating the easy assembly and disassembly of the powder collection box.

[0030] In this embodiment, one end of the rotating shaft 302 is exposed at the front end of the powder collection box 1 (the end in the pulling direction is the front), and a control arm 4 is fixedly provided at the exposed end of the rotating shaft 302; the control arm 4 is provided with a locking device 5 for locking itself to the powder collection box 1. By exposing one end of the rotating shaft 302 at the front end of the powder collection box 1 and providing the control arm 4, it is convenient to rotate the rotating shaft 302 manually, which is convenient to operate, simplifies the structure, and reduces the overall manufacturing cost. Here, the control arm 4 is also a handle, which facilitates driving the rotating shaft 302 to rotate. At the same time, by providing the locking device 5 on the control arm 4, the rotation angle position of the rotating shaft 302 can be locked, which is simple in structure and facilitates precise control of the height position of the powder collection box 1.

[0031] In this embodiment, the locking device 5 is a ball screw, and the powder collection box 1 is provided with a first locking groove 102 and a second positioning groove 103 for positioning the ball screw. In actual use, the ball of the ball screw springs up and engages in the first locking groove 102 or the second positioning groove 103, thus locking the rotating shaft 302. The positions of the first locking groove 102 or the second positioning groove 103 correspond to the lowered and raised positions of the powder collection box, respectively. The locking device 5 used in this structural design is simple in structure and easy to operate.

[0032] In this embodiment, at least two support blocks 301 are provided along the length of the receiving groove 101. It is understood that there are also two sets of corresponding drive structures. The rotating shafts 302 share a common shaft, meaning that the lifting and lowering control of the support blocks 301 is achieved by the rotating shafts 302. By providing at least two support blocks 301, the support stability of the powder collection box 1 is further improved, thereby providing a more uniform lifting force to the powder collection box 1 and further improving the sealing reliability of the connection between the powder collection box 1 and the vacuum cleaner housing 2.

[0033] In this embodiment, two sets of guide plates 201a are fixedly provided on the bottom surface of the powder collection box mounting cavity 201, arranged parallel to the sliding direction of the powder collection box 1. The powder collection box 1 is slidably disposed between the two sets of guide plates 201a. By setting the structure of two sets of guide plates 201a, it is beneficial to ensure the stable positioning of the powder collection box 1 and the smoothness of pushing the powder collection box 1 in.

[0034] In this embodiment, the top of the powder collecting box 1 is provided with a detachable and sealingly connected powder collecting box cover 6. The box opening 1a is located on the powder collecting box cover 6, and the top surface of the powder collecting box cover 6 is provided with a sealing ring 7 arranged around the box opening. Specifically, one end of the powder collecting box cover 6 is hinged to the powder collecting box 1, and the other end is snapped into place. A sealing ring is provided between the powder collecting box cover 6 and the powder collecting box 1 to complete the seal between the powder collecting box cover 6 and the powder collecting box 1. By providing the powder collecting box cover 6, the cover 6 can be opened to quickly clean the inside of the powder collecting box 1 after the powder collecting box 1 is removed. At the same time, the structure of the sealing ring 7 and its placement on the powder collecting box cover 6 facilitates the replacement and maintenance of the sealing ring. Furthermore, the sealing ring has a simple structure and good sealing performance.

[0035] The dust collection device of this household vacuum cleaner operates on the following principle: When disassembling the dust collection box 1, rotating the rotating shaft 302 causes the dust collection box 1 to fall a certain distance, allowing it to be easily removed. The installation process of the dust collection box 1 is the reverse of the disassembly process and will not be described in detail here. During disassembly and assembly, there is no friction between the sealing structure between the dust collection box 1 and the vacuum cleaner housing 2, effectively improving the reliability of the household vacuum cleaner.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
