[0025] The utility model will be further explained in detail in combination with the drawings and embodiments, and these drawings are all simplified schematic views, only the basic structure of the utility model is schematically shown, so it only shows the structure related to the utility model.

[0026] Embodiment one

[0027] As shown in Figure 1 A ground brush structure for a dust collector, comprising a base 1, a cover plate 4, a rolling brush assembly 5 and a sealing element; the cover plate 4 is installed on the base 1, and an air duct 6 is arranged between the two; the base 1 is provided with an air inlet 2 communicating with the air duct 6; the rolling brush assembly 5 is installed on the inner side of the cover plate 4, and its bottom extends to the lower side of the base 1 through the air inlet 2; and the sealing element is connected to the base 1 at the front end of the air inlet 2, and is also located on the front side of the rolling brush assembly 5.

[0028] The ground brush is usually used in cooperation with a dust collector main machine; the dust collector main machine generates negative pressure to suck external air and dirt into the air inlet 2 and then into the corresponding filtering and storing device (such as an existing dust cup) along the air duct 6; the rolling brush assembly 5 comprises a rolling brush body capable of rotating independently, which contacts the ground, and the bristles of the rolling brush body can brush off the dirt that is difficult to be directly sucked into the ground, and then the dirt is sucked into the filtering and storing device by the negative pressure.

[0029] In the above process, when the ground brush moves and encounters larger particles of dirt in front, the sealing element can be pushed to float horizontally to increase the opening of the air inlet 2 so that the dirt can smoothly enter the air duct 6; without being pushed, the sealing element is in a vertical state, which can reduce the opening of the air inlet 2, thereby increasing the air suction and improving the cleaning effect.

[0030] Further, the air inlet 2 is usually provided on the bottom of the base 1, and has different shapes, such as rectangular and circular; the air inlet 2 here adopts a rectangular structure, and the front end of the air inlet 2 has a wind guide groove, and the sealing element is installed in the wind guide groove; the opening size of the air inlet 2 can be controlled by the floating of the sealing element in the wind guide groove.

[0031] The air guide groove is part of the air inlet 2, and the air inlet 2 is communicated with the air guide groove, and the air inlet 2 is downwardly opened, the air guide groove is downwardly opened at the bottom, and the air guide groove is transversely opened at the front and rear ends, one end is outwardly communicated with the outside, and the other end is inwardly communicated with the air inlet 2.

[0032] The sealing piece is in a sheet structure, is vertically arranged in an initial state, and can be flipped and deformed to block or dredge the air guide groove, so that the opening size of the air inlet 2 changes.

[0033] According to the relationship between flow and flow rate in fluid mechanics, the flow is proportional to the flow rate in the case of a given cross-sectional area.

[0034] Since the output power of the dust collector main machine is constant, the air flow driven by the negative pressure generated by the dust collector main machine is also constant, that is, the air flow sucked by the dust collector main machine is constant when the dust collector main machine works.

[0035] The greater the speed of air flow, the greater the momentum, and the greater the suction force generated.

[0036] Embodiment Two

[0037] Based on the embodiment one, the utility model discloses the material and corresponding installation mode of sealing piece.

[0038] As shown in Figure 2 The sealing piece is made of soft blocking strip 3, the upper end of the blocking strip 3 is provided with a buckle, the top of the air guide groove is provided with a clamping groove, and the buckle can be embedded in the clamping groove.

[0039] The blocking strip 3 is made of soft rubber material, which can be elastically deformed after being subjected to external force and restored to its original state after the external force is removed.

[0040] The longitudinal section of the baffle 3 is T-shaped structure, and after the baffle 3 is embedded into the base 1, the baffle 3 can be fixed by pressing or the cover plate 4. The clamping groove provided on the top of the air guide groove penetrates the side wall of the air guide groove, the baffle 3 passes through the clamping groove from top to bottom, the upper part of the baffle 3 is clamped in the clamping groove, and the baffle 3 is fixed in the clamping groove by the pressing of the cover plate 4 above the base 1.

[0041] Or the baffle 3 is fixed in the clamping groove by the pressing block, and the pressing block is located between the cover plate 4 and the base 1, and can be fixed on the base 1 by screws or other fasteners, and at the same time, the pressing block is located above the clamping groove, so that the baffle 3 can be tightly pressed and fixed in the clamping groove.

[0042] In addition, the sealing element can not only be fixed by encapsulation and finally rely on the elastic deformation of the material itself to increase and decrease the air inlet 2, but also can be fixed by the rotating shaft 7 to increase and decrease the air inlet 2 by rotating.

[0043] As shown in Figure 3 The sealing element adopts a hard or soft push piece 8, and the push piece 8 is rotatably installed on the top of the air guide groove through the rotating shaft 7. That is, the push piece 8 is rotatably connected with the base 1 through the rotating shaft 7, and the rotating shaft 7 is installed on the top of the air guide groove and penetrates the upper part of the push piece 8.

[0044] The hard push piece 8 is made of hard rubber material and cannot be elastically deformed by itself. The push piece 8 is fixedly connected with the rotating shaft 7, and the rotating shaft 7 is rotatably connected with the base 1, so that when the push piece 8 encounters a large amount of dirt, the push piece 8 can rotate forward and backward around the axis of the rotating shaft 7, and the size of the air inlet 2 can also be controlled.

[0045] The soft push piece 8 is made of soft rubber material, which can be elastically deformed when subjected to external force, and can rotate forward and backward around the axis under the action of the rotating shaft 7. Therefore, the soft push piece 8 can not only control the size of the air inlet 2 by turning itself, but also can achieve this function by the characteristics of the material itself.

[0046] In addition, the floating mode of the aforementioned sealing element is passive turning or deformation after being subjected to force. Similarly, the sealing element can also be actively turned by a corresponding driving mechanism. For example, a corresponding linkage mechanism can be provided between the rotating shaft 7 and the rollers of the floor brush, or a separate driving mechanism can be specially designed for the rotation of the rotating shaft 7, so as to achieve the purpose of artificially controlling the size of the air inlet 2.

[0047] Embodiment three

[0048] On the basis of the first and second embodiments, the sealing element can also be installed at the air inlet 2 in the form of a whole segment or multiple segments.

[0049] The multi-section structure is that a plurality of protrusions 9 are arranged in the air guide groove, the plurality of protrusions 9 are distributed in a straight line and equidistantly spaced, and a corresponding sealing piece is arranged between two adjacent protrusions 9, so that the sealing piece can control the size of the air inlet 2 in a multi-section structure.

[0050] As shown in Figures 4-5 The dial piece 8 is taken as an example, the dial piece 8 is also rotatably installed through the rotating shaft 7, and the rotating shaft 7 can also adopt a whole-section or multi-section corresponding structure, that is, a plurality of dial pieces 8 are connected in series by one rotating shaft 7, or one rotating shaft 7 is arranged corresponding to each dial piece 8.

[0051] The former facilitates the overall disassembly of the dial piece 8, and only needs to place the dial piece 8 in the corresponding position and sequentially pass through the series connection by the same rotating shaft 7; the latter facilitates the replacement and maintenance of a certain dial piece 8, and only needs to remove the rotating shaft 7 and the dial piece 8 at the corresponding position when replacing, without affecting the use of other dial pieces 8.

[0052] The whole-section structure is that a whole sealing piece is integrally installed in the air guide groove, for example, a whole blocking strip 3 is installed in the air guide groove in a way of being clamped and matched with the clamping groove through the rubber coating, or a whole dial piece 8 is rotatably installed in the air guide groove through the rotating shaft 7.

[0053] When the sealing piece adopts the multi-section structure, the corresponding sealing piece can be pushed to float according to the specific position of the dirt, instead of the whole floating when encountering large-particle dirt; when the sealing piece adopts the whole-section structure, the design structure is simple and the installation is convenient; therefore, compared with the whole-section structure, the multi-section structure is more accurate and detailed in controlling the size of the air inlet 2, and can avoid the dramatic increase or decrease of the size of the air inlet 2, thereby affecting the dirt treatment effect of other positions.

[0054] In summary, the utility model discloses a floor brush structure for a dust collector, which adopts a sealing piece to make a whole-section or multi-section sealing and shielding structure of soft rubber or hard rubber at the front end inlet of the roller brush assembly 5, and the sealing structure is fixed by the rotating shaft 7 to make rotary motion or changes the opening size of the air inlet 2 by the elastic deformation of the material itself, so that the dust collector floor brush has good cleaning effect on both hard ground and soft ground.
