Description

Technical Field

[0001] This utility model relates to the technical field of cleaning equipment accessories, and in particular provides a dust collection box and cleaning equipment. Background Technology

[0002] Cleaning equipment such as robot vacuums and sweeping and mopping machines require users to clean or replace the filters regularly during daily use. However, users may encounter problems such as incorrect installation direction or missing filters during the disassembly and assembly process, which can ultimately affect the air permeability of the filters or allow dirt to directly enter the fan. Utility Model Content

[0003] The purpose of this invention is to provide a dust collection box and cleaning equipment, which aims to solve the problem that the filter screen in the existing dust collection box is prone to being missing or incorrectly installed.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] In a first aspect, embodiments of this application provide a dust collection box, comprising:

[0006] The box body has a receiving cavity inside;

[0007] A dust box cover, which is detachably connected to the box body and covers the opening end of the receiving cavity;

[0008] A filter assembly disposed within the receiving cavity; and,

[0009] A filter leak-proof installation mechanism includes a swinging member rotatably connected to the inner wall of the receiving cavity. When the filter assembly is not installed in the receiving cavity and the dust box cover is on the box body, the swinging member interferes with the dust box cover, preventing the dust box cover from closing with the box body. When the filter assembly is installed in the receiving cavity and the dust box cover is on the box body, the filter assembly interferes with the swinging member, eliminating the interference between the swinging member and the dust box cover, allowing the dust box cover to close with the box body.

[0010] The accommodating cavity is also provided with an anti-inversion limiting part, and the filter assembly is provided with a limiting fitting part that is adapted to the anti-inversion limiting part to ensure that the filter assembly is installed in the correct direction in the accommodating cavity.

[0011] The beneficial effects of this utility model are as follows: When the filter assembly is installed in the dust collection box of this utility model, the anti-inversion limiting part and the limiting fitting part are adapted to prevent the filter assembly from being installed backwards in the receiving cavity. Furthermore, when the filter assembly is not installed in the receiving cavity, the dust box cover cannot be closed with the box body, prompting the user to install the filter assembly. Only when the filter assembly is installed in the receiving cavity can the dust box cover be closed with the box body. The dust collection box provided by this application, through its physical structure, prevents the filter assembly from being missed or installed backwards, thereby improving the user experience.

[0012] In some embodiments, the oscillating member includes a first interference portion that interferes with the dustbin cover and a second interference portion that interferes with the filter assembly;

[0013] When the filter assembly is not installed in the receiving cavity, the first interference portion abuts against the dust box cover, so that the dust box cover cannot be closed to the box body;

[0014] When the filter assembly is installed into the receiving cavity, the second interference part abuts against the filter assembly, causing the swinging member to swing, thereby unlocking the positional relationship between the first interference part and the dust box cover, and the dust box cover closes to the box body.

[0015] By adopting the above technical solution, the first interference part and the second interference part of the swinging component alternately interfere with the dust box cover and the filter assembly respectively, so that when the filter assembly is not installed in the receiving cavity, the interference between the first interference part and the dust box cover is not eliminated and cannot be closed with the box body.

[0016] In some embodiments, the first interference portion has a first interference surface that abuts against the dustbin cover, and the first interference surface is a plane; or...

[0017] The second interference portion has a second interference surface that abuts against the filter assembly, and the second interference surface is an arc-shaped surface.

[0018] By adopting the above technical solution, the first interference surface, which is planar, has a larger contact area with the dust box cover, and the stability of the first interference part abutting against the dust box cover is higher. That is, when the filter assembly is not installed in the receiving cavity, the first interference part maintains a stable state for a longer time when it interferes with the dust box cover. Furthermore, the second interference surface, which is arc-shaped, has a smaller contact area with the filter assembly. When the filter assembly is installed in the receiving cavity, it abuts against the second interference part, which can generate a thrust on the second interference part and drive the overall swing component to rotate, thereby eliminating the interference effect between the first interference part and the dust box cover, and the dust box cover can be smoothly closed with the box body.

[0019] In some embodiments, the dust box cover is provided with a plug portion that abuts against the first interference surface, the plug portion protruding from the inner wall surface of the dust box cover.

[0020] By adopting the above technical solution, the sensitivity of the interference between the protruding plug portion and the first interference surface can be further improved. That is, in space, the degree of interference between the dust box cover and the first interference portion is increased.

[0021] In some embodiments, the accommodating cavity is provided with a support portion, and the swing member is provided with a rotating shaft portion that is rotatably connected to the support portion.

[0022] By adopting the above technical solution, the rotating part of the swinging component is rotatably connected to the supporting part, so as to satisfy the swinging component to swing around the axis relative to the box.

[0023] In some embodiments, the filter anti-leakage mechanism further includes a reset member, which is sleeved on the rotating shaft portion so that when the filter assembly is removed from the receiving cavity, the first interference portion is reset to a position state that abuts against the dust box cover.

[0024] By adopting the above technical solution, the reset efficiency of the swinging component is increased by using the reset component, especially in the next cycle when the filter assembly needs to be replaced, so as to satisfy the first interference part and the dust box cover being in a state of interference.

[0025] In some embodiments, the anti-tipping limiting part includes a rib provided on the inner wall of the receiving cavity; the limiting mating part includes a mounting groove formed on the filter assembly, and the rib is inserted into the mounting groove.

[0026] By adopting the above technical solution, the ribs are adapted to the mounting groove to achieve positive installation of the filter assembly in the accommodating cavity.

[0027] In some embodiments, the dust box cover has a pin on one side and a buckle on the other side. The buckle is positioned to correspond to the position of the filter anti-leakage mechanism. The box body has a slot for inserting into the pin and a snap-fit ​​groove for engaging with the buckle.

[0028] By adopting the above technical solution, the dust box cover is initially positioned by engaging with the slot on the box body through a pin, and then the dust box cover is secured to the box body by engaging with the snap-fit ​​groove through a buckle.

[0029] In some embodiments, the dust box cover is further provided with a limiting structure for limiting the up-and-down movement of the filter assembly in the insertion direction, and the limiting structure abuts against the filter assembly.

[0030] By sampling the above technical solution, when the dust box cover is closed on the box body, the limiting structure acts as a stop against the filter assembly, thereby limiting the range of movement of the filter assembly in the installation direction.

[0031] Secondly, this application also provides a cleaning device, including a cleaning body and a dust collection box as described above, the dust collection box being disposed within the cleaning body.

[0032] The beneficial effects of this utility model are as follows: The cleaning equipment of this utility model can use the filter anti-leakage installation mechanism on the dust collection box to remind the user to install the filter assembly, thereby preventing unfiltered air from being discharged. At the same time, it can also prevent dust from affecting the service life of the fan. Attached Figure Description

[0053] Cleaning appliances such as robotic vacuum cleaners and sweeper-mop combos require users to regularly clean or replace their filters during daily use. However, users often encounter problems such as incorrect filter installation or missing filters during installation. Typically, the exhaust vent is located on the side of the cleaning appliance. When the filter is at 0° or 180° to the airflow direction of the exhaust vent, the pleats of the filter's HEPA filter extend parallel to the airflow direction generated by the fan. This allows air to flow along the channels formed by the pleats, reducing turbulence resistance and ensuring even airflow through the gaps between the pleats, preventing localized blockages. If installed incorrectly, the airflow directly impacts the sides of the pleats, increasing resistance and causing particles to accumulate at the pleat corners, accelerating filter clogging. This highlights the importance of correct filter installation. Similarly, if the filter is missing, unfiltered air is exhausted, increasing the probability of dirt entering the fan and ultimately affecting its lifespan.

[0054] In view of this, the dust collection box provided in this application has an anti-inversion limiting part in the receiving cavity of the box body, and a limiting fitting part adapted to the anti-inversion limiting part on the filter assembly to ensure that the filter assembly is installed in the correct direction in the receiving cavity; and, a filter anti-leakage mechanism is added in the receiving cavity of the box body. When the filter assembly is not installed in the receiving cavity and the dust box cover is on the box body, the swinging member interferes with the dust box cover, so that the dust box cover cannot be closed with the box body; when the filter assembly is installed in the receiving cavity and the dust box cover is on the box body, the filter assembly interferes with the swinging member to eliminate the interference between the swinging member and the dust box cover, so that the dust box cover is closed with the box body.

[0055] Please refer to Figures 1 to 4 In one aspect, embodiments of this application provide a dust collection box 100, including a box body 10, a dust box cover 20, a filter assembly 30, and a filter anti-leakage mechanism 40.

[0056] The housing 10 includes a receiving cavity 10a; a dust box cover 20 is detachably connected to the housing 10 and covers the opening of the receiving cavity 10a; a filter assembly 30 is disposed within the receiving cavity 10a; and a filter anti-leakage mechanism 40 includes a swing member 41 rotatably connected to the inner wall of the receiving cavity 10a; wherein the receiving cavity 10a has an anti-inversion limiting part 10b, and the filter assembly 30 has a limiting fitting part 30a adapted to the anti-inversion limiting part 10b, to ensure that the filter assembly 30 is in the receiving cavity. The installation direction within the cavity 10a is correct; and, when the filter assembly 30 is not installed in the cavity 10a and the dust box cover 20 is placed on the box body 10, the swing member 41 interferes with the dust box cover 20, preventing the dust box cover 20 from closing with the box body 10; when the filter assembly 30 is installed in the cavity 10a and the dust box cover 20 is placed on the box body 10, the filter assembly 30 interferes with the swing member 41, eliminating the interference between the swing member 41 and the dust box cover 20, so that the dust box cover 20 closes with the box body 10.

[0057] Understandably, the housing 10 is the main structure of the dust collection box 100, used to carry and support various components. For example, it provides a accommodating cavity 10a for installing the filter assembly 30, and the dust box cover 20 is installed on the housing 10 to seal the filter assembly 30. The dust box cover 20 is used to block the opening of the accommodating cavity 10a of the housing 10 to fix and limit the filter assembly 30. The filter assembly 30 is used to filter dirt from the air and adsorb dirt. The function of the filter anti-leakage mechanism is to remind the user that the filter assembly 30 is not installed in the accommodating cavity 10a. The swinging member 41 in the filter anti-leakage mechanism 40 is rotatably connected to the inner wall of the accommodating cavity 10a, so it can swing around its axis accordingly during use to meet the requirement of the swinging member 41 interfering with the dust box cover 20. The swing member 41 should have two states. One of them is the initial state of the swing member 41. In the initial state, the filter assembly 30 is not placed in the receiving cavity 10a. At this time, when the dust box cover 20 is placed on the box body 10 to block the opening of the receiving cavity 10a, the dust box cover 20 cannot be closed with the box body 10 due to the interference between the swing member 41 and the dust box cover 20. Here, the interference between the swing member 41 and the dust box cover 20 refers to the spatial structural stacking or compression. That is, the swing member 41 protrudes outward in the opposite direction of the dust box cover 20 covering the box body 10 and abuts against the dust box cover 20, so that the dust box cover 20 cannot fit tightly with the opening of the receiving cavity 10a. Another working state is that of the swinging member 41. In this working state, the filter assembly 30 is placed in the receiving cavity 10a. At this time, the filter assembly 30 first interferes with the swinging member 41 and comes into contact with it. Then, the swinging member 41 rotates around the axis. At this time, the swinging member 41 releases its interference with the dust box cover 20 due to the rotation around the axis, so that the dust box cover 20 can be closed with the box body 10. That is, the swinging member 41 in the filter anti-leakage mechanism 40 realizes the switching between the initial state and the working state by rotating relative to the inner wall of the receiving cavity 10a.

[0058] Here, the dust box cover 20 being in a closed state with the box body 10 means that the dust box cover 20 tightly seals the opening end of the receiving cavity 10a of the box body 10, and there is no warping or mismatch in size.

[0059] The dust collection box 100 of this utility model features an anti-inversion limiting part 10b that mates with the limiting fitting part 30a when the filter assembly 30 is installed. This prevents the filter assembly 30 from being installed backwards within the receiving cavity 10a. Furthermore, when the filter assembly 30 is not installed within the receiving cavity 10a, the dust box cover 20 cannot close to the box body 10, prompting the user to install the filter assembly 30 into the box body 10. Only when the filter assembly 30 is installed within the receiving cavity 10a can the dust box cover 20 close to the box body 10. The dust collection box 100 provided by this application, through its physical structure, prevents the filter assembly 30 from being missed or installed backwards, thereby improving the user experience.

[0060] Please refer to Figures 2 to 4 In some embodiments, the swing member 41 includes a first interference portion 411 that interferes with the dust box cover 20 and a second interference portion 412 that interferes with the filter assembly 30, wherein the first interference portion 411 is connected to the second interference portion 412.

[0061] When the filter assembly 30 is not installed in the receiving cavity 10a, the first interference part 411 abuts against the dust box cover 20, so that the dust box cover 20 cannot be closed with the box body 10;

[0062] When the filter assembly 30 is installed into the receiving cavity 10a, the second interference part 412 abuts against the filter assembly 30, causing the swing member 41 to swing, thereby unlocking the positional relationship between the first interference part 411 and the dust box cover 20, and the dust box cover 20 closes to the box body 10.

[0063] Understandably, the first interference part 411 and the second interference part 412 are two parts of the swing member 41 that interfere with and abut against the dust box cover 20 and the filter assembly 30, respectively. The two interference parts rotate synchronously around the axis to allow the swing member 41 to switch between the initial state and the working state.

[0064] Here, when the filter assembly 30 is not installed in the receiving cavity 10a and the first interference part 411 abuts against the dust box cover 20, the swing member 41 is in the initial state; while when the filter assembly 30 is installed in the receiving cavity 10a, the filter assembly 30 interferes with and abuts against the second interference part 412, and at this time, the swing member 41 rotates around the axis as a whole, so that the first interference part 411 rotates around the axis together with the second interference part 412, and the first interference part 411 separates from the dust box cover 20 and releases the positional relationship of interference.

[0065] Thus, the first interference portion 411 and the second interference portion 412 of the swing member 41 alternately interfere with the dust box cover 20 and the filter assembly 30 respectively, so that when the filter assembly 30 is not installed in the receiving cavity 10a, the interference between the first interference portion 411 and the dust box cover 20 is not eliminated and it cannot be closed with the box body 10.

[0066] Please refer to Figures 2 to 4 In some embodiments, the first interference portion 411 has a first interference surface 411a that abuts against the dustbin cover 20, and the first interference surface 411a is a plane; and / or,

[0067] The second interference section 412 has a second interference surface 412a that abuts against the filter assembly 30, and the second interference surface 412a is an arc-shaped surface.

[0068] Understandably, the first interference surface 411a, which is planar, has a larger contact area with the dust box cover 20, and the stability of the first interference part 411 abutting against the dust box cover 20 is higher. That is, when the filter assembly 30 is not installed in the receiving cavity 10a, the first interference part 411 and the dust box cover 20 maintain a stable state for a longer time when they interfere. Furthermore, the second interference surface 412a, which is arc-shaped, has a smaller contact area with the filter assembly 30. When the filter assembly 30 is installed in the receiving cavity 10a, it abuts against the second interference part 412, which can generate a thrust on the second interference part 412, thereby driving the overall swing member 41 to rotate. This eliminates the interference effect between the first interference part 411 and the dust box cover 20, and the dust box cover 20 is smoothly closed with the box body 10.

[0069] Furthermore, when the dust box cover 20 abuts against the first interference surface 411a, the oscillating member 41 is in a stable state, that is, the oscillating member 41 will not be triggered to rotate around the axis at this time; while when the filter assembly 30 abuts against the second interference surface 412a, the oscillating member 41 is in a dynamic state, that is, the oscillating member 41 will be triggered to rotate around the axis.

[0070] Please refer to Figure 2 and Figure 9 In some embodiments, the dust box cover 20 is provided with a plug portion 20a that abuts against the first interference surface 411a, and the plug portion 20a protrudes from the inner wall surface of the dust box cover 20.

[0071] Understandably, the plug-in portion 20a is a protruding structure that protrudes from the surface of the dust box cover 20. The structural form of the plug-in portion 20a includes, but is not limited to, a plug-in block, a plug-in post, a plug-in rib, etc. That is, the setting of the plug-in portion 20a shortens the distance between the surface of the dust box cover 20 and the first interference surface 411a, and can meet the interference requirements of the two without adjusting the size of the first interference portion 411.

[0072] Thus, by utilizing the protruding insertion part 20a to interfere with the first interference surface 411a, the sensitivity of their interference can be further enhanced. That is, spatially, the degree of interference between the dust box cover 20 and the first interference part 411 is increased.

[0073] Please refer to Figure 5 and Figure 6In some embodiments, the accommodating cavity 10a is provided with a support portion 10c, and the swing member 41 is provided with a rotating shaft portion 42 that is rotatably connected to the support portion 10c.

[0074] Understandably, the support part 10c is a structural member that is connected to the inner wall of the accommodating cavity 10a and remains stationary, while the rotating shaft part 42 is a structural member that rotates relative to the support member about an axis.

[0075] For example, the support portion 10c consists of two U-shaped structural members formed within the accommodating cavity 10a, which are spaced apart from each other. Additionally, each swing member 41 has a pivot portion 42 along the direction of the rotation axis, with each pivot portion 42 mounted on a corresponding U-shaped structural member. Of course, in other examples, the support member may also be a Y-shaped structural member, an O-shaped structural member, etc.

[0076] Thus, the rotating part of the swing member 41 is rotatably connected to the support part 10c to satisfy the swing member 41 swinging about the axis relative to the box body 10.

[0077] Please refer to Figure 6 In some embodiments, the filter screen anti-leakage mechanism 40 further includes a reset member 43, which is sleeved on the rotating shaft portion 42 so that when the filter screen assembly 30 is removed from the accommodating cavity 10a, the first interference portion 411 is reset to a position state that abuts against the dust box cover 20 and interferes.

[0078] Understandably, the swing member 41 should first maintain its initial state during use, and then switch to the working state under the action of the filter assembly 30. Therefore, when the filter assembly 30 is removed from the accommodating cavity 10a, the first interference part 411 of the swing member 41 needs to be restored to its initial state.

[0079] The structure of the reset component 43 includes, but is not limited to, torsion springs, leaf springs, and springs.

[0080] Thus, the reset member 43 is used to increase the reset efficiency of the swing member 41, especially in the next cycle when the filter assembly 30 needs to be replaced, so as to satisfy the first interference part 411 and the dust box cover 20 being in a state of interference.

[0081] Please refer to Figure 7 and Figure 8 In some embodiments, the anti-tipping limiting part 10b includes a rib provided on the inner wall of the accommodating cavity 10a; the limiting mating part 30a includes a mounting groove opened on the filter assembly 30, and the rib is inserted into the mounting groove.

[0082] Understandably, the installation direction of the filter assembly 30 within the receiving cavity 10a is determined by the matching of the ribs with the mounting groove.

[0083] For example, a rib can be provided on each of the two diagonal inner walls of the receiving cavity 10a. Similarly, an installation groove can be provided at the corresponding position on the diagonal side wall of the filter assembly 30. Only when both ribs are inserted into the corresponding installation grooves can the filter assembly 30 be installed into the receiving cavity 10a in the correct installation direction.

[0084] Here, the anti-tipping limiting part 10b can also be a protrusion or a protrusion, and the limiting fit can also be formed in a through hole or blind hole on the filter assembly 30.

[0085] In this way, by using the ribs to fit the mounting groove, the filter assembly 30 can be installed in the accommodating cavity 10a in the forward direction.

[0086] Please refer to Figure 7 and Figure 9 In some embodiments, the dust box cover 20 has a pin 20b on one side and a buckle 20c on the other side. The buckle 20c is positioned to correspond to the position of the filter anti-leakage mechanism 40. The box body 10 has a slot 10d that is inserted into the pin 20b, and the box body 10 also has a snap-fit ​​groove 10e that engages with the buckle 20c.

[0087] Understandably, the process of the dust box cover 20 being placed on the box body 10 is as follows: First, the pin 20b on one side of the dust box cover 20 is inserted obliquely into the slot 10d on the box body 10. Then, with the slot 10d as the rotation point, the other side of the dust box cover 20 moves toward the snap-fit ​​groove 10e until the buckle 20c is snapped into the snap-fit ​​groove 10e, so as to complete the dust box cover 20 being closed with the box body 10.

[0088] Here, the filter anti-leakage mechanism 40 is set in correspondence with the buckle 20c. So, when the dust box cover 20 and the box body 10 are connected by the buckle 20c, the filter anti-leakage mechanism 40 in the initial state can interfere with the dust box cover 20 and prevent the dust box cover 20 from being fully connected.

[0089] Of course, the dust box cover 20 can also be plugged into or threaded onto the box body 10.

[0090] Thus, the dust box cover 20 is initially positioned by engaging with the slot 10d on the box body 10 via the pin 20b, and then engages with the snap-fit ​​groove 10e via the snap-fit ​​20c to allow the dust box cover 20 to be placed on the box body 10.

[0091] Please refer to Figure 9 In some embodiments, the dust box cover 20 is also provided with a limiting structure 20d for limiting the up and down movement of the filter assembly 30 in the insertion direction, and the limiting structure 20d abuts against the filter assembly 30.

[0092] Understandably, after the dust box cover 20 is closed with the box body 10, there should be a certain installation gap between the dust box cover 20 and the filter assembly 30 to allow for installation clearance, so that the dust box cover 20 can be placed over the opening of the receiving cavity 10a. Then, while allowing clearance, the filter assembly 30 also needs to be confined within the receiving cavity 10a, especially its range of motion in the insertion direction. Therefore, a limiting structure 20d is provided on the dust box cover 20.

[0093] Here, the structural form of the limiting structure 20d includes, but is not limited to, limiting protrusions, limiting ribs, and limiting protrusions.
