Description

Technical Field

[0001] This utility model relates to the technical field of sweeping machines, and more specifically, to a dust collection box and a sweeping machine. Background Technology

[0002] With the rapid development of smart home technology, intelligent robotic vacuum cleaners, as a typical representative of service robots, have been widely used in home cleaning scenarios. This device, through the coordinated action of a brushing mechanism and a vacuum adsorption device, transfers debris from the floor through a suction channel to a built-in dust collection unit, thereby achieving automated cleaning. In existing technologies, to ensure the effective operation of the vacuum adsorption system, it is usually required that the dust collection unit maintain a vacuum state, which places stringent technical requirements on the sealing performance of the dust collection container.

[0003] The current mainstream solution in the industry uses a double-layer cover seal, which involves adding an inner cover with an elastic silicone layer inside the dust collection box cover. Sealing is achieved by compressing and deforming the elastic silicone layer through the bottom cover flange. However, this structure has significant drawbacks: firstly, the multi-layer composite cover structure increases mold complexity, leading to higher injection molding costs; secondly, the elastic silicone layer is prone to stress relaxation under long-term compression; and thirdly, the cumulative effect of assembly tolerances can easily lead to localized seal failure, resulting in a high leakage rate. Utility Model Content

[0004] The purpose of this utility model is to provide a dust collection box and a sweeper to solve the technical problems of complex sealing structure, high cost and easy failure of the dust collection box in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] By adopting the above technical solution, the entire periphery of the dust collection box is sealed by an inner wall compression seal between the cover and the box body. The sealing structure is simple, the sealing cost of the seal is low, and the sealing reliability is high, reducing the possibility of dust collection box failure.

[0010] By adopting the above technical solution, the stability of the seal when installed in the mounting groove is improved.

[0011] In one embodiment, the limiting segment is provided with a limiting structure for limiting the seal, the limiting structure being a limiting bone structure.

[0012] By adopting the above technical solution, the seal is confined within the limiting section.

[0013] In one embodiment, the extending direction of the limiting segment is perpendicular to the extending direction of the mounting segment.

[0014] By adopting the above technical solution, the firmness of the seal in the mounting groove is further improved.

[0015] In one embodiment, the mounting section includes a mounting base groove and mounting side grooves perpendicularly connected to both sides of the mounting base groove. The mounting base groove and the mounting side grooves enclose each other to form a "U"-shaped groove structure. The width of the mounting base groove is smaller than the cross-sectional width of the seal, and the height of the mounting side groove is smaller than the cross-sectional width of the seal.

[0016] By adopting the above technical solution, the sealing element and multiple parts of the installation section are brought into contact, while also ensuring that the sealing element and the sealing part are in contact.

[0017] In one embodiment, the seal has a circular, square, or polygonal cross-section.

[0018] By adopting the above technical solution, the shape of the seal can be selected with high flexibility, and it is not limited to a circle.

[0019] In one embodiment, a dust collection chamber communicating with a filter duct is formed between the housing and the cover. The inner wall of the cover is provided with a filter assembly mounting cavity located in the dust collection chamber and a filter assembly located in the filter assembly mounting cavity. The filter assembly communicates with the dust collection chamber.

[0020] By adopting the above technical solution, the filter components are directly installed inside the dust collection box, which simplifies the structure, greatly reduces manufacturing costs, and improves the sealing reliability of the filtration system.

[0021] In one embodiment, the filtration assembly includes a first filter element having a primary filter screen and a second filter element having a high-efficiency filter screen stacked with the first filter element.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. The specific implementation of this utility model is described in more detail below with reference to specific embodiments:

[0042] like Figures 1 to 3 As shown in the figure, this utility model provides a dust collection box, which is used in a sweeper to collect dust sucked in by the sweeper. The dust collection box provided in this embodiment needs to form a sealed dust collection cavity to prevent dust from leaking out of the dust collection box. Therefore, the dust collection box needs a good sealing structure to seal the dust collection cavity. The dust collection box provided in this embodiment has good sealing performance, simple structure, low manufacturing cost, and high reliability. The following is a detailed description of the specific implementation method:

[0043] Please refer to the following: Figure 4 and Figure 5 The dust collection box in this embodiment includes:

[0044] A box body 1, a cover 2 placed on the box body 1, and a seal 3 disposed between the box body 1 and the cover 2; a dust collection chamber 10 is formed between the box body 1 and the cover 2; either the box body 1 or the cover 2 is provided with a mounting groove 4, the mounting groove 4 extends along the mounting trajectory of the seal 3, the mounting groove 4 is provided with a mounting opening 41, the opening direction of the mounting opening 41 is perpendicular to the mounting movement direction Y of the cover 2, and the seal 3 is accommodated in the mounting groove 4 and partially exposed outside the mounting opening 41 (e.g., Figure 6 and Figure 7 The other of the box body 1 or the cover body 2 is provided with a sealing part 6 that covers the mounting groove 41 and abuts against the sealing member 3. When the sealing part 6 abuts against the sealing part 4, the sealing member 3 abuts against the groove wall of the mounting groove 4 to form a sealing structure for sealing the dust collection chamber 10.

[0045] Specifically, the box body 1 refers to a component of the dust collection box; the box body 1 can be connected with the cover body 2 to form the dust collection chamber 10.

[0046] The cover 2 refers to another component of the dust collection box; the cover 2 can be placed on the box body 1, and the two are connected by a hinge structure. Of course, in actual application scenarios, there are various ways to connect the two, and it is not limited to the hinge method.

[0047] The box body 1 and the cover body 2 are connected by a selection shaft and can be opened and closed freely. The dust collection box is equipped with an air inlet (garbage inlet) and a dust baffle. When the sweeper sucks in garbage, the dust baffle will open due to the vacuum suction. It is designed with a limit device to facilitate garbage suction. When the sweeper stops vacuuming, the dust baffle will automatically close to prevent garbage from being ejected.

[0048] The sealing element 3 refers to the component used to seal the dust collection chamber 10 formed between the box body 1 and the cover body 2. When the cover body 2 is placed on the box body 1, a gap inevitably forms at the joint. The sealing element 3 seals this gap, thus sealing the dust collection chamber 10. It should be further explained that the sealing element 3 includes, but is not limited to, sealing rings. The sealing element 3 is elastic and can deform under external force, thereby improving the sealing effect. The sealing ring is a compressible soft material, including but not limited to silicone, rubber, EVA, etc.

[0049] In this embodiment, either the box body 1 or the cover 2 is provided with a mounting groove 4, and the other box body 1 or the cover 2 is provided with a sealing part 6. The description focuses on the box body 1 having a sealing part 6 and the cover 2 having a mounting groove 4. A sealing element 3 is installed in the gap between the box body 1 and the cover 2. To ensure the sealing element 3 is positioned between the box body 1 and the cover 2, it is housed in the mounting groove 4. The mounting groove 4 extends along the installation trajectory of the sealing element 3, thus confining the sealing element 3 within the predetermined installation trajectory. The mounting groove 4 has a mounting opening 41, the opening direction of which is perpendicular to the installation movement direction Y of the cover 2. Therefore, the opening direction of the mounting opening 41 is not directly opposite the cover 2. The shape and size of the sealing element 3 match the shape and size of the mounting groove 4, allowing the sealing element 3 to be perfectly housed within the mounting groove 4, while a portion of the sealing element 3 protrudes beyond the mounting opening 41. When the cover 2 is placed on the box 1, the sealing part 6 abuts against the sealing element 3. At the same time, the sealing part 6 applies force to the sealing element 3, causing the sealing element 3 to abut against the groove wall of the mounting groove 4. In this way, the sealing part 6 abuts against the sealing element 3, and the sealing element 3 abuts against the groove wall of the mounting groove 4, forming at least two sealing structures, so that the dust collection chamber 10 is closed.

[0050] By adopting the above technical solution, the entire periphery of the dust collection box is sealed by an inner wall compression seal 3 between the cover 2 and the box 1. The sealing structure is simple, and the sealing cost of the seal 3 is low, and the sealing reliability is high, reducing the possibility of dust collection box failure.

[0051] Please refer to it again. Figure 5 In one embodiment, the mounting groove 4 includes a mounting section 42 and a limiting section 43 connected to the mounting section 42. The mounting section 42 is provided with a mounting opening 41, and the limiting section 43 is provided with a limiting opening 44 communicating with the mounting opening 41. The opening direction of the limiting opening 44 is perpendicular to the opening direction of the mounting opening 41.

[0052] Specifically, the mounting groove 4 includes a mounting section 42 and a limiting section 43. Because the seal 3 is elastic, when installed in the mounting groove 4, the seal 3 needs to be fitted onto the cover 2, and then embedded into the mounting groove 4 by the elasticity of the seal 3. At this time, the elasticity of the seal 3 may cause it to fall out of the mounting groove 4. Therefore, the mounting groove 4 includes a mounting section 42 and a limiting section 43 communicating with the mounting section 42. The limiting section 43 is used to limit the seal 3. The mounting section 42 has a mounting opening 41, and the limiting section 43 has a limiting opening 44. The opening directions of the two are perpendicular to each other, making it difficult for the seal 3 to fall out of the two perpendicular openings simultaneously.

[0053] By adopting the above technical solution, the stability of the seal 3 when installed in the mounting groove 4 is improved.

[0054] In one embodiment, the limiting segment 43 is provided with a limiting structure 45 for limiting the sealing member 3, and the limiting structure 45 is a limiting bone structure.

[0055] Specifically, the limiting structure 45 refers to the structure used to limit the movement of the sealing member 3; in this embodiment, the limiting structure 45 is a limiting rib structure, which is a structure protruding from the groove wall of the limiting section 43, and is used to limit the movement of the sealing member 3.

[0056] By adopting the above technical solution, the sealing element 3 is confined in the limiting section 43.

[0057] In one embodiment, the extending direction of the limiting segment 43 is perpendicular to the extending direction of the mounting segment 42.

[0058] Specifically, the limiting section 43 and the mounting section 42 extend along the installation trajectory of the seal 3, and the limiting section 43 and the mounting section 42 are set perpendicularly, so that the seal 3 is also set along the extension direction of the limiting section 43 and the mounting section 42, making it difficult for the seal 3 to fall off from the limiting section 43 and the mounting section 42.

[0059] By adopting the above technical solution, the firmness of the seal 3 in the mounting groove 4 is further improved.

[0060] Please refer to it again. Figure 7 In one embodiment, the mounting section 42 includes a mounting base groove 421 and mounting side grooves 422 that are perpendicularly connected to both sides of the mounting base groove 421. The mounting base groove 421 and the mounting side grooves 422 enclose each other to form a "U"-shaped groove structure. The width of the mounting base groove 421 is less than the cross-sectional width of the seal 3, and the height of the mounting side groove 422 is less than the cross-sectional width of the seal 3.

[0061] Specifically, when the seal 3 is housed in the mounting section 42, it abuts against the mounting bottom groove 421 and the mounting side groove 422. At the same time, the seal 3 deforms under the pressure of the mounting bottom groove 421 and the mounting side groove 422, which improves the sealing performance of the seal 3. In addition, the groove height of the mounting side groove 422 is less than the width of the cross-section of the seal 3, so that the seal 3 can be exposed outside the mounting section 42 when it is housed in the mounting section 42, which is conducive to abutting against the sealing part 6.

[0062] By adopting the above technical solution, the sealing element 3 and multiple parts of the installation section 42 are abutted, and the sealing element 3 and the sealing part 6 are also abutted.

[0063] In one embodiment, the seal 3 has a circular, square, or polygonal cross-section.

[0064] By adopting the above technical solution, the shape of the seal 3 is highly flexible and is not limited to a circle.

[0065] Please refer to it again. Figure 3 and Figure 4 In one embodiment, a dust collection chamber 10 communicating with a filter duct is formed between the housing 1 and the cover 2. The inner wall of the cover 2 is provided with a filter assembly mounting cavity 20 located in the dust collection chamber 10 and a filter assembly 5 located in the filter assembly mounting cavity 20. The filter assembly 5 communicates with the dust collection chamber 10.

[0066] By adopting the above technical solution, the filter component 5 is directly installed inside the dust collection box, which has a simple structure, greatly reduces manufacturing costs, and improves the sealing reliability of the filtration system.

[0067] In one embodiment, the filter assembly 5 includes a first filter element 51 having a primary filter screen and a second filter element 52 having a high-efficiency filter screen stacked on top of the first filter element 51.

[0068] Specifically, the first filter element 51 refers to a filter element with a pre-filter, which is used to intercept larger particles, such as hair, dust, and debris, to prevent them from entering the subsequent precision components; the second filter element 52 refers to an element with a high-efficiency filter, which is used after the pre-filter to process finer particles, such as PM2.5 or allergens.

[0069] By adopting the above technical solution, fine filtration of the dust collection box was achieved.

[0070] In one embodiment, the first filter element 51 is provided with a snap-fit ​​structure 511 that snaps into the mounting cavity of the filter assembly 5, and the first filter element 51 limits the second filter element 52 when the snap-fit ​​structure 511 snaps into the mounting cavity of the filter assembly 5.

[0071] Specifically, the snap-fit ​​structure 511 refers to a structure that can be fixed to a target position by snap-fit. More specifically, the snap-fit ​​structure 511 has snap-fit ​​claws, which are used to fix in the snap-fit ​​groove of the target position, thereby realizing the snap-fit ​​connection.

[0072] By adopting the above technical solution, the snap-fit ​​structure 511 of the first filter element 51 enables the second filter element 52 to be fixed in the installation cavity of the filter assembly 5. Its limiting method is simple and easy to install and remove.

[0073] In other embodiments, the first filter element 51 is not limited to the inverted connection method, but also includes other installation and fixing methods.

[0074] In other embodiments, the first filter element 51 is also provided with a handle 512, which is located on the side of the first filter element 51 away from the filter assembly mounting cavity 20, so as to facilitate the operator to disassemble and install the first filter element 51.

[0075] Secondly, a sweeping machine is provided, including a sweeping machine body and the aforementioned dust collection box, the dust collection box being installed on the sweeping machine body.

[0076] By adopting the above technical solution, the sweeper of this embodiment has the advantage of good sealing performance, in addition to the advantages of the dust collection box in the above embodiments.

[0077] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
