Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of cleaning equipment, and more particularly to a dust cup and a mite remover.BACKGROUND

[0002] With an improvement of people's living standards and pursuit of a healthy home environment, a mite remover utilized as a specialized cleaning tool is increasingly attracting consumer attention and favor. A main function of the mite remover is to effectively remove mites, dust and allergens from the home environment through various technical means so as to improve living environment and protect people's health.

[0003] In an existing mite remover, a dust collection chamber has some shortcomings. A dust collection component absorbs dust and mites through the dust collection chamber. A dust collection box and a fan are arranged in a staggered pattern, and the dust collection box is detached from a housing of the mite remover in a horizontal direction, which results in low spatial utilization of the dust collection component in the mite remover. Furthermore, in a traditional suction type dust collection mechanism, after an airflow around the mite remover is drawn in by a power component, the airflow carries dust, mites and other foreign matter into the dust collection box. Solid foreign matter is collected by the dust collection box, and the airflow is discharged from an air outlet of the dust collection box. However, allergens and mites may also be secondarily discharged into living space along with the discharged airflow, leading to unsatisfactory cleaning effectiveness.

[0004] Therefore, how to improve a utilization rate of the dust collection chamber and enhance a dust removal effectiveness of the mite remover is a technical problem that needs to be urgently resolved currently.SUMMARY

[0005] An objective of the present disclosure is to provide a dust cup and a mite remover, which can increase a proportion of a cup body cavity utilized as a dust collection chamber, reduce dust leakage and reduce frequency of short-term disassembly by users, enhance user experience and obtain a wide range of applications.

[0016] In some embodiments, the roller brush includes a roller and a plurality of brush strips arranged on an outer wall of the roller, and the plurality of brush strips are rotationally distributed around a central axis of the roller on the outer wall of the roller.

[0017] In some embodiments, each of the plurality of brush strip includes a connecting portion connected with the roller and a beating portion connected with the connecting portion, and the beating portion has a baseball-bat shaped cross-section.

DETAILED DESCRIPTION

[0027] As mentioned above, the dust cup of existing mite remover still needs to be improved.

[0028] According to the present disclosure, a rotary separator and an inner wall of a cup body are internally tangent and connected to form a contact curved surface at a junction where a dust ejection port meets the inner wall of the cup body, and a curvature radius of the rotary separator at the junction where the dust ejection port meets the inner wall of the cup body is smaller than a curvature radius of the cup body at the junction where the dust ejection port meets the inner wall of the cup body. On one hand, a gap between the rotary separator and the cup body is reduced, which can prevent dust from the dust ejection port from clogging at the dust ejection port; on the other hand, the outer wall of the rotary separator and the inner wall of the cup body are internally tangent and connected, which can enhance an integration between the rotary separator and the cup body, reduce the gap between the rotary separator and the cup body, increase an effective volume of a dust collection chamber, thereby improving a volume ratio of the dust collection chamber. Moreover, a smaller curvature radius of the rotary separator can allow dust to be thrown out from the dust ejection port and directly enter the dust collection chamber along the outer wall of the rotary separator, which can reduce dust adhesion, avoid dust backflow, further improve a utilization rate of the dust collection chamber, and obtain a wide range of applications.

[0029] To make above objectives, features and advantages of the present disclosure more apparent and understandable, specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0030] First, referring to FIGS. 1 to 3, a dust cup 100 includes a cup body 101 and a rotary separator 102.

[0031] The cup body 101 has a cup body cavity 101a. The rotary separator 102 is arranged in the cup body cavity 101a. A portion of the cup body cavity 101a between the rotary separator 102 and the cup body 101 is configured as a dust collection chamber 103. The rotary separator 102 is provided with a dust ejection port 104. At a junction 110 where the dust ejection port 104 meets an inner wall of the cup body 101, an outer wall of the rotary separator 102 and the inner wall of the cup body 101 are internally tangent and connected to form a contact curved surface 105. A curvature radius of the rotary separator 102 at the junction 110 where the dust ejection port 104 meets the inner wall of the cup body 101 is smaller than a curvature radius of the cup body 101 at the junction 110 where the dust ejection port 104 meets the inner wall of the cup body 101.

[0032] In some embodiments, the rotary separator 102 and the inner wall of the cup body 101 are internally tangent and connected to form the contact curved surface 105 at the junction 110 where the dust ejection port 104 meets the inner wall of the cup body 101, and the curvature radius of the rotary separator 102 at the junction 110 where the dust ejection port 104 meets the inner wall of the cup body 101 is smaller than the curvature radius of the cup body 101 at the junction 110 where the dust ejection port 104 meets the inner wall of the cup body 101. On one hand, a gap between the rotary separator and the cup body is reduced, which can prevent dust from the dust ejection port from clogging at the dust ejection port; on the other hand, the outer wall of the rotary separator and the inner wall of the cup body are internally tangent and connected, which can enhance an integration between the rotary separator and the cup body, reduce the gap between the rotary separator and the cup body, increase an effective volume of the dust collection chamber, thereby improving a volume ratio of the dust collection chamber. Moreover, a smaller curvature radius of the rotary separator can allow dust to be thrown out from the dust ejection port and directly enter the dust collection chamber along the outer wall of the rotary separator, which can reduce dust adhesion, avoid dust backflow, further improve a utilization rate of the dust collection chamber, and obtain a wide range of applications.

[0033] In some embodiments, referring to FIG. 8, a symmetry line of the cup body 101 is L2, and a symmetry line of the rotary separator 102 is L1. The cup body 101 and the rotary separator 102 on one side of the symmetry line L2 are completely in contact with each other to form the contact curved surface 105, which can greatly reduce the gap between the cup body 101 and the rotary separator 102.

[0034] In some embodiments, except for the contact curved surface 105, the gap exists between the outer wall of the rotary separator 102 and the inner wall of the cup body 101 and serves as the dust collection chamber 103.

[0035] In some embodiments, referring to FIG. 9, the contact curved surface 105 can also be only the curved surface corresponding to the junction 110.

[0036] In some embodiments, the rotary separator 102 includes a separation cup body 102a and a separation component 102b. The separation cup body 102a has a separation chamber 102c. The separation component 102b is arranged in the separation chamber 102c. The separation component 102b can rotate in a first rotation direction (indicated by an arrow on the separation component 102b in the figure). The dust ejection port 104 extends from the junction 110 where the dust ejection port 104 meets the inner wall of the cup body 101 along the first rotation direction.

[0037] In some embodiments, referring to FIGS. 1 and 8, a cross-sectional shape of the separation cup body 102a is circular, which can ensure good centrifugal force.

[0038] In some embodiments, the cross-sectional shape of the separation cup body 102a may also be elliptical, etc.

[0039] In some embodiments, a volume ratio of the separation chamber 102c to the dust collection chamber 103 is 1:1.6 to 1:2.

[0040] In some embodiments, referring to FIG. 3, the dust cup further includes an air inlet 106 and an air outlet 107 penetrating a bottom of the cup body cavity 101a. The separation component 102b is arranged above the air outlet 107. A shape of the air outlet 107 matches with a shape of a bottom of the separation component 102b. The air inlet 106 and the air outlet 107 are coaxially arranged. The air inlet 106 is arranged tangentially to the separation cup body 102a, which can optimize an airflow path and improve separation efficiency.

[0041] In some embodiments, the separation component 102b is provided with a plurality of through-holes 102d. A filtering component (not shown in the figure) is arranged between the separation component 102b and the air outlet 107.

[0042] In some embodiments, the through-holes 102d are configured to separate larger dust particles, and the filtering component is configured to further filter fine particles in the airflow, which can further improve dust removal effectiveness.

[0043] In some embodiments, referring to FIG. 1, the separation cup body 102a is further provided with a sealing rib 108. The sealing rib 108 and the contact curved surface 105 are arranged on two opposite sides of the dust ejection port 104. A surface of the sealing rib 108 extends beyond a surface of the dust ejection port 104.

[0044] In some embodiments, the dust cup 100 further includes a cup cover 109 (see FIG. 4) matching with the cup body 101. After the cup cover 109 covers the cup body 101, the cup cover 109 is in sealing contact with the sealing rib 108, thus the separation cup body has a relatively sealed space, which can prevent clogging of the separation component caused by dust leaking into the separation cup body, thereby improving separation effectiveness.

[0045] In some embodiments, after the cup cover 109 is placed on the cup body 101, the separation cup body 102a and the cup cover 109 form a passage at the dust ejection port 104. Air containing dust enters the rotary separator 102 from the air inlet 106. Under a centrifugal force of the separation component 102b, the dust is thrown out from the dust ejection port 104 along the first rotation direction and deposits into the dust collection chamber 103. The air separated from the dust is filtered by the through-holes 102d on the separation component 102b and filtered by the filtering component, and then is discharged from the air outlet 107. As the gap between the rotary separator 102 and the cup body 101 in a direction opposite to a movement direction of the dust is eliminated, which can improve dust separation effectiveness, increase the proportion of the cup body cavity 101a utilized as the dust collection chamber 103, reduce dust leakage and reduce frequency of short-term disassembly by users, enhance user experience and obtain a wide range of applications.

[0046] In some embodiments, the rotary separator 102 and the cup body 101 are eccentrically arranged, which can cause the rotary separator 102 to generate an asymmetric centrifugal force field during rotation. This centrifugal force field can more effectively push liquid or particles in the cup body to move in a specific direction, thereby speeding up separation process, helping to break vortices and stagnant areas in the dust, and allowing for more sufficient separation between dust and air.

[0047] Correspondingly, referring to FIG. 4, the present disclosure further provides a mite remover 200. The mite remover 200 includes the dust cup 100 and a main machine 201. The dust cup 100 is arranged on the main machine 201.

[0048] In some embodiments, the rotary separator 102 and the inner wall of the cup body 101 are internally tangent and connected to form the contact curved surface 105 at the junction 110 where the dust ejection port 104 meets the inner wall of the cup body 101, and the curvature radius of the rotary separator 102 at the junction 110 where the dust ejection port 104 meets the inner wall of the cup body 101 is smaller than the curvature radius of the cup body 101 at the junction 110 where the dust ejection port 104 meets the inner wall of the cup body 101. On one hand, a gap between the rotary separator and the cup body is reduced, which can prevent dust from the dust ejection port from clogging at the dust ejection port; on the other hand, the outer wall of the rotary separator and the inner wall of the cup body are internally tangent and connected, which can enhance an integration between the rotary separator and the cup body, reduce the gap between the rotary separator and the cup body, increase an effective volume of the dust collection chamber, thereby improving a volume ratio of the dust collection chamber. Moreover, a smaller curvature radius of the rotary separator can allow dust to be thrown out from the dust ejection port and directly enter the dust collection chamber along the outer wall of the rotary separator, which can reduce dust adhesion, avoid dust backflow, further improve a utilization rate of the dust collection chamber, enhance dust removal effectiveness and user comfort of the mite remover, and obtain a wide range of applications.

[0049] In some embodiments, the main machine 201 includes a suction motor (not shown) for generating negative pressure airflow and a roller brush motor (not shown) for driving a roller brush 202 to rotate. A rotational speed of the suction motor is in a range of 38700 RPM to 473000 RPM, and a rotational speed of the roller brush motor is in a range of 8640 RPM to 10560 RPM.

[0050] In some embodiments, referring to FIG. 5, the roller brush 202 includes a roller 202a and a plurality of brush strips 202b arranged on an outer wall of the roller 202a. The plurality of brush strips 202b are rotationally distributed around a central axis of the roller 202a on the outer wall of the roller 202a.

[0051] In some embodiments, referring to FIG. 6, the brush strip 202b includes a connecting portion 202b-2 connected with the roller 202a and a beating portion 202b-1 connected with the connecting portion 202b-2. The beating portion 202b-1 has a baseball-bat shaped cross-section.

[0052] In some embodiments, the baseball-bat shaped cross-section of the beating portion 202b-1 helps to provide a larger beating area, which is conducive to beating fabrics and improving fabric dust removal effectiveness.

[0053] In some embodiments, the brush strips 202b are rotationally distributed on an outer wall of the roller 202a around the central axis of the roller 202a, which can help to form a more uniform beating force, thereby reducing damage to fabrics.

[0054] In some embodiments, referring to FIG. 7, the main machine 201 is provided with a handle 203. The handle 203 has an inclination angle α of 8° to 10° relative to a surface of the main machine 201. This angle is more ergonomic, which can help to improve user satisfaction.

[0055] In some embodiments, referring to FIG. 4, the main machine 201 is further provided with a button 204 for controlling turn-on and turn-off of the suction motor and the roller brush motor, and the button is arranged on the handle 203.

[0056] Although the present disclosure has been disclosed above, the present disclosure is not limited thereto.
