Description

Technical Field

[0001] The present invention relates to the field of household electrical appliances, and in particular to cleaning equipment, such as vacuuming, mopping, sweeping and the like. Background Art

[0002] Cleaning equipment is usually equipped with a dust bucket for collecting dust and other dirt. There is usually a fluid-connected pipe between the dust bucket and the main body of the equipment, and the pipe allows air or dust and other dirt to pass through. A sealing component can be set at the connection position between the dust bucket and the main body of the equipment to prevent gas or dust from escaping. The existing sealing component structure is relatively complex. In order to ensure the sealing quality, it is usually necessary to install it in an embedded manner with both the main body of the equipment and the dust bucket. Such a setting is not convenient for the dust bucket to be removed from the main body of the equipment. Some sealing components with simple structures can be imagined, but sealing components with simple structures are prone to poor sealing effects and fatigue damage after long-term use.

[0003] In addition, there is still room for improvement in some aspects of existing cleaning equipment. For example: there are few alignment feature structures between the dust bucket and the equipment body, which makes it easy for the dust bucket to deviate from the correct installation position during installation; the sealing structure between the handle and the equipment body is too complicated, making it inconvenient to remove the handle from the equipment; the installation connection structure between the cleaning liquid tank and the equipment for containing the cleaning liquid is not convenient to operate; the mounting frame structure of the motor of the vibrating component is too simple, which makes the motor easily damaged during use and has a short service life; the vacuum cleaning part of the cleaning equipment has complex pipes and wires, and usually requires additional components to accommodate or carry these pipes and wires, which increases the overall volume of the structure and increases the manufacturing cost.

[0004] Therefore, it is necessary to provide a cleaning device to at least partially solve the above problems. Summary of the invention

The sealing component has a double-layer elastic wall structure, and is therefore not easily deformed even after long-term use.

[0006] The cleaning device of the present invention also provides some preferred settings in other aspects. For example, the present invention adds an alignment structure between the dust collecting component and the device body to further avoid problems such as shaking and displacement of the dust collecting component during installation; improves the sealing structure between the handle and the device body to facilitate the installation and disassembly of the handle; improves the installation and connection structure between the cleaning liquid storage tank and the device body to facilitate the installation and disassembly of the cleaning liquid storage tank; improves the structure of the motor mounting bracket to avoid excessive shaking of the motor during use and can effectively extend the service life of the motor; integrates a part of the wall surface of the cleaning device and the part that accommodates and carries the wires, pipes and other structures into one, saving space and saving manufacturing costs.

[0114] The cleaning device according to the present invention will be described in detail below with reference to the accompanying drawings. The following are only preferred embodiments according to the present invention, and those skilled in the art can think of other ways to implement the present invention based on the preferred embodiments, and other ways also fall within the scope of the present invention.

[0115] The present invention provides a cleaning device, such as a vacuum cleaner, and in particular, a vacuum cleaner with a mopping function. First of all, it should be noted that the direction and position terms of the present invention should be understood as relative directions and positions. These direction and position terms should refer to the normal orientation of the cleaning device in use (e.g. Figure 1 ) to explain.

[0116] Figure 1-Figure 16 The cleaning device 100 according to some preferred embodiments of the present invention is shown. Figure 1 and Figure 2 The cleaning device 100 includes a main body 20, a handle 10 mounted on the top of the main body 20, and a cleaning device 50 mounted on the bottom of the main body 20. The top of the handle 10 is formed with a gripping section 11. The cleaning device 50 is used to directly contact the surface to be cleaned and is formed into a plate-like structure. Figure 1 and Figure 2 The plate-like structure extends generally along a horizontal plane from the perspective shown, and can pivot relative to the main body 20 in the use state. The main body 20 has a main body top section 21, a main body bottom section 23, and a main body side section 22 connected between the main body top section 21 and the main body bottom section 23. The cleaning device 100 also includes a cleaning liquid storage device 40 installed on the main body top section 21, and a dust collecting device 30 installed between the main body top section 21 and the main body bottom section 23. The dust collecting device 30, the cleaning liquid storage device 40 and the main body 20 together form a generally cylindrical structure.

[0117] The dust collecting device 30 has two fluid passages respectively connected to the main body 20: a dirt inlet 31 formed on the side wall of the dust collecting device 30 and an air outlet 33 formed on the top wall 34 of the dust collecting device 30. Figure 3 The inlet 241 of the dust suction pipe 24 of the cleaning device 100 is formed on the cleaning device 50, that is, arranged near the bottom of the cleaning device 100; the outlet 242 of the dust suction pipe 24 (see Figure 8) is formed at a substantially central position of the main body side section 22 of the main body 20 and is connected to the dirt inlet 31 of the dust collecting device 30. A suction device 211, such as a fan, is provided in the main body top section 21 of the main body 20. The suction device 211 sucks the gas from the dust collecting device 30 into the main body top section 31 through the air outlet 33. A filtering device positioned between the dirt inlet 31 and the air outlet 33 is provided in the dust collecting device 30. The filtering device further includes a first-stage filtering component 32 mainly used for filtering large particles and a second-stage filtering component 36 mainly used for filtering small particles. It can be understood that under the suction action of the suction device 211, the dirt on the surface to be cleaned enters the dust collecting device 30 together with the air through the dust suction pipe 24. Subsequently, the clean air after two-stage filtration in the dust collecting device 30 enters the main body top section 31 through the air outlet 33, and is finally discharged from the equipment exhaust hole 215 (see Figure 1 )discharge.

[0118] Figure 4 The structure of the sealing member 25 at the connection position between the air outlet 33 of the dust collecting device 30 and the air inlet 26 of the main body top section 31 is shown. The sealing member 25 is, for example, a sealing ring. The sealing member 25 is made of a soft and elastic material such as silicone as a whole, and has a mounting section 251 for mounting the sealing member 25 and a sealing section that plays a sealing role. The mounting section 251 and the main body top section 21 are snap-fitted together. The sealing section includes an annular inner wall 2522, an annular outer wall 2521, and a connecting wall 2523 connected to the bottom of the inner wall 2522 and the outer wall 2521. The top end of the outer wall 2521 is connected to the mounting section 251, and the top end of the inner wall 2522 is a free end. The connecting wall 2523 is constructed to smoothly transition from the bottom end of the inner wall 2522 to the bottom end of the outer wall 2521, that is, the connection area between the inner wall 2522 and the outer wall 2521 does not have edges and corners. In the example Figure 4 In the cross-sectional view shown, the cross-sectional profile of the connecting wall 2523 is formed into a substantially semicircular shape. In other embodiments not shown, the cross-sectional profile of the connecting wall 2523 can also be formed into a teardrop shape, which means that the radial dimension near its bottom is the largest and the radial dimension at a position slightly closer to the top is slightly smaller. In other embodiments not shown, the cross-sectional profile of the connecting wall 2523 can be formed into other arcs, such as a 1 / 4 circle.

[0119] In some embodiments not shown, the sealing member may not be configured as a sealing ring. The sealing member may be a non-annular member having an outer side wall, an inner side wall and an arc-shaped connecting wall similar to the above-mentioned sealing member.

[0120] In particular, the annular inner wall 2522 and the annular outer wall 2521 are both circular ring structures around the axis X1, and the axial dimensions of the inner wall 2522 and the outer wall 2521 are substantially equal. In other embodiments not shown, the sealing member 25 has an overall shape that matches the shape of the air outlet 33. For example, the inner wall and the outer wall can also be configured as an ellipse or a square according to the air outlet 33 being an ellipse or a square, and the axis thereof can be a straight line passing through the center point of its projected profile.

[0121] The connecting wall 2523 of the sealing member 25 is used to press against the top wall 34 of the dust collecting device 30 around the air outlet 33. The dust collecting device 30 and the main body 20 are separated and their respective views are shown in FIG. Figure 5 and Figure 6 The sealing member 25 is pre-installed on the main body top section 21 of the main body 20. When the dust collecting device 30 is installed on the main body 20, the sealing member 25 and the top wall 34 of the dust collecting device 30 are in contact and pressed together. There is no need for the dust collecting device 30 and the sealing member 25 to have a connection relationship such as snap fit.

[0122] Such a configuration of the sealing member 25 can not only play a good sealing role, but also facilitate the installation and removal of the dust collecting device 30. In addition, since the sealing member 25 has a double-layer elastic wall structure, it is not easy to deform even after long-term use.

[0123] In the above embodiment, the air inlet 26 on the top section 21 of the main body constitutes a "first gas passage opening", and the air outlet 33 of the dust collecting device 30 constitutes a "second gas passage opening". In other embodiments not shown, the first gas passage opening and the second gas passage opening may be other passage openings, for example, the first gas passage opening and the second gas passage opening may be the outlet of the dust suction pipe and the dirt inlet of the dust collecting device. In other words, the sealing member of the above embodiment may also be applied to the position where other gas passage openings are joined.

[0124] Continue to refer Figure 5 and Figure 6 A locking tongue 341 is provided on the top wall 34 of the dust collecting device 30, and a locking tongue receiving groove 212 is formed on the bottom wall of the main body top section 21. Figure 6-Figure 8The dust collecting device 30 and the main body 20 have a variety of alignment feature structures to facilitate accurate positioning of the dust collecting device 30 and prevent the dust collecting device 30 from shaking or shifting during the installation of the dust collecting device 30. For example, a first positioning feature structure 351 is provided at the position where the dust collecting device 30 and the main body side section 22 meet, and the main body side section 22 has a second positioning feature structure 221 corresponding to the first positioning feature structure 351. The first positioning feature structure 351 is a rib positioned near the bottom of the dust collecting device 30 and extending toward the side wall along the first horizontal direction H1, and the second positioning feature structure 221 is a side wall. Preferably, there are two ribs, and the two ribs are arranged side by side in the second horizontal direction H2 perpendicular to the first horizontal direction H1.

[0125] It can be understood that during the installation process of the dust collecting device 30, when the top wall 34 of the dust collecting device 30 begins to contact the sealing member 25, the sealing member 25 is elastically compressed and exerts a certain elastic force on the dust collecting device 30, causing the dust collecting device 30 to shake and thus be inaccurately positioned. At this time or before this time, the first positioning feature structure 351 and the second positioning feature structure 221 begin to engage, which can prevent the dust collecting device 30 from shaking and shifting when the sealing member 25 contacts the dust collecting device 30. Therefore, the first positioning feature structure 351 and the second positioning feature structure 221 can be positioned so that: during the installation process of the dust collecting device 30, when the top of the dust collecting device 30 approaches the sealing member 25, the first positioning feature structure 351 and the second positioning feature structure 221 begin to engage.

[0126] In some embodiments, there may be other positioning feature structures between the dust collecting device 30 and the main body 20. For example, a positioning groove 352 extending along the first horizontal direction H1 is provided at the bottom of the dust collecting device 30, and a positioning protrusion 231 corresponding to the positioning groove 352 is provided on the top surface of the main body bottom section 23; a positioning block 353 protruding toward the bottom side is provided at a position close to the bottom of the dust collecting device 30 and away from the main body side section 22, and a receiving recess 232 corresponding to the positioning block is provided on the main body bottom section 23, and the positioning protrusion 231 and the receiving recess 232 are separated by a partition wall 233. Preferably, when the dust collecting device 30 is installed on the main body 20, the outer surface of the positioning block 353 is flush with the outer surface of the main body bottom section 23.

[0127] When the dust collecting device 30 is installed, the positioning block 353 and the receiving recess 232 are first engaged, and the dust collecting device 30 pivots around the positioning block 353 so that the positioning groove 352 of the dust collecting device 30 engages with the positioning protrusion 231, whereby the partition wall is positioned between the positioning block 353 and the positioning groove 352. When the top wall 34 of the dust collecting device 30 is about to contact the sealing member 25, the ribs and the side walls (i.e., the first positioning feature structure 351 and the second positioning feature structure 221) begin to engage. As shown in Figure 7, in one embodiment, the top wall 34 is at an angle to the vertical direction (i.e., perpendicular to the direction of the plane defined by the H1 direction and the H2 direction), and the angle is, for example, an acute angle, and the vertical direction is parallel to the longitudinal direction of the cleaning device. When the dust collecting device 30 rotates into the locked position, the top wall 34 abuts against the sealing member 25, thereby forming a sealed engagement.

[0128] It should be noted that the terms "first positioning feature structure" and "second positioning feature structure" mentioned in the present invention are only used to distinguish the various components. In fact, the various components can have different naming methods. For example, the positioning block 353 can be called the first positioning part, the receiving recess 232 can be called the first positioning corresponding part corresponding to the first positioning part; the part marked with 351 in the figure can be called the second positioning part, and the part marked with 221 in the figure can be called the second positioning corresponding part corresponding to the second positioning part.

[0129] Reference below Fig. 9 In some embodiments, the sealing structure between the handle 10 and the main body 20 also has a structure similar to the sealing member 25. For the convenience of description, the sealing structure between the handle 10 and the main body 20 is referred to as the second sealing member 216. The handle 10 is an elongated structure and is detachably mounted on the main body top section 21. The second sealing member 216 is mounted at the handle receiving port of the main body top section 21. The second sealing member 216 has a sealing section 214 that abuts against the outer periphery of the handle 10. In the cross section passing through the center line of the handle 10, the cross-sectional profile of the sealing section 214 is formed into an arc shape, such as a semicircular, 1 / 4 circular or teardrop shape. Further, the sealing section includes a top wall 2141, a bottom wall 2142, and a transition section 2143 that is smoothly connected between the radial inner ends of the top wall 2141 and the bottom wall 2142. The radial outer end of the top wall 2141 is fixed on the mounting section of the second sealing member 216, and the radial outer end of the bottom wall 2142 is free.

[0130] The second sealing member 216 also has the same advantages as the sealing member 25. For example, the second sealing ring configuration can not only play a good sealing role, but also facilitate the installation and removal of the handle 10. In addition, the second sealing member 216 is not easily deformed after long-term use because it has a double-layer elastic wall structure.

[0133] In some preferred embodiments, there are also some preferred arrangements for the installation and connection structure of the cleaning liquid storage device 40. These preferred arrangements are as follows: Figure 10-13 Shown in.

[0134] First reference Fig.10 A locking latch 41 and a button 42 fixedly connected to the locking latch 41 are provided at the top of the cleaning liquid storage device 40. The locking latch 41 is configured to be able to move between a locking position extending into the locking latch receiving groove 222 of the top section 21 of the main body and an unlocking position separated from the top section 21 of the main body under the drive of the button 42. In particular, an elastic member 43 is provided between the locking latch 41 and the main body 20 of the cleaning liquid storage device 40. When the locking latch 41 is in the unlocking position, the elastic member 43 accumulates force and has a biasing force to bias the locking latch 41 toward the locking position. The locking latch 41 and the button 42 can be integrally formed. A one-way valve 44 is also provided near the top of the cleaning liquid storage device 40 to replenish air into the cleaning liquid storage device 40 after the cleaning liquid is discharged.

[0135] Go to Fig.11 The cleaning liquid storage device 40 has a bottom cover assembly 45, and a retainer 47 is provided at the bottom of the bottom cover assembly 45.

[0136] The three-dimensional structure of the retaining member 47 is Fig.12 As shown in the figure, it can be seen that the bottom of the retaining member 47 has a cleaning liquid discharge pipe 472 extending toward the bottom side, and the retaining member 47 has two opposite wings 473 and 474 extending horizontally. The two wings 473 and 474 are hollow tubular structures, and the two tubular structures have a common axis D1. Fig.13 Shows Fig.11 Another cross-sectional view of the component is shown, the cross-section being defined jointly by the axis X2 of the mounting post and the axis D1 of the tubular structure formed by the wings 473 , 474 , in which the two wings 473 , 474 are shown.

[0137] Go to Fig.13 , it can be seen that the wings 473, 474 are received in the corresponding receiving portion 223 in the main body top section 21. Since the wings 473, 474 are tube structures and the receiving portion 223 is a cylindrical receiving cavity, the retaining member 47 can rotate as a whole in the direction D1 (see Fig.12 ) is rotated to a certain angle, which facilitates the installation and removal of the cleaning liquid storage device 40. It can be understood that the holder 47 for receiving the cleaning liquid storage device 40 pivots and shakes, which can provide an optimal engagement angle and facilitate the alignment of the cleaning liquid storage device 40. Preferably, the pair of wings 473 and 474 have different diameters, and the bottom surface of the wing 473 with a large diameter is flush with the bottom surface of the body of the holder 47.

[0138] In some embodiments, a motor 52 is installed in the cleaning device 50 to provide vibration to the cleaning device 50. Fig.14 In some embodiments, the motor mounting bracket 53 may also have an improved structure. Fig.14 The motor mounting frame 53 on the bottom cover 51 of the cleaning device 50 is shown, which includes a mounting base 531 and a circle of circumferential sections 532 extending from the mounting base 531 to the top side. The circumferential sections 532 surround the motor 52 in a shape matching the motor 52. Preferably, the circumferential sections 532 cover an area exceeding 1 / 2 of the axial dimension of the motor 52. More preferably, the circumferential sections 532 cover an area of ​​1 / 2-3 / 4 of the axial dimension of the motor 52. Such a setting can prevent the motor 52 from shaking excessively during use and can effectively extend the service life of the motor 52.

The cleaning device 50 includes a mounting frame 54 for receiving the connecting member 60. The mounting frame 54 is an integral member. A portion 541 of the mounting frame 54 constitutes a portion of the outer surface of the cleaning device 50. The structure of the cleaning device 50 after the top wall 34 and other components are removed is shown in FIG. Fig.16 As shown in the figure, it can be seen that the mounting frame 54 also includes an extension section 542 in the cleaning device 50, and the extension section 542 is configured to cover or carry the wires or pipes in the cleaning device 50. There are two extension sections 542, and the two extension sections 542 extend from the main body of the mounting frame 54 in partially opposite directions. Compared with the traditional solution that requires additional covering or carrying parts to cover or carry wires or pipes, the embodiment of the present invention integrates a part of the wall surface of the cleaning device 50 and the part that accommodates and carries the wires, pipes and other structures into one, saving space and manufacturing costs.

[0140] Through the discussion of the above embodiments, it can be known that the seal at the connection area between the dust collecting component and the main body of the present invention can not only play a good sealing role, but also facilitate the installation and removal of the dust collecting component, and the sealing component has a double-layer elastic wall structure, so it is not easy to deform after long-term use. The present invention also adds an alignment structure between the dust collecting component and the device body to further avoid the problems of shaking and displacement of the dust collecting component during installation; improves the sealing structure between the handle and the device body to facilitate the installation and removal of the handle; improves the installation and connection structure between the cleaning liquid storage tank and the device body to facilitate the installation and removal of the cleaning liquid storage tank; improves the structure of the motor mounting bracket to avoid excessive shaking of the motor during use, and can effectively extend the service life of the motor; integrates a part of the wall surface of the cleaning device and the part that accommodates and carries the wires, pipes and other structures into one, saving space and manufacturing costs.
