Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a dust cup and a mite remover. Background Technology

[0002] With the improvement of people's living standards and the pursuit of a healthy home environment, mite removers, as a professional cleaning tool, are receiving increasing attention and favor from consumers. The main function of a mite remover is to effectively remove mites, dust, and allergens from the home environment through various technological means, thereby improving the living environment and protecting people's health.

[0003] In existing mite removers, the use of the dust collection chamber has some shortcomings. The dust collection component absorbs dust and mites, but in current technology, the dust box and fan are arranged alternately, and the dust box is detached horizontally from the mite remover's casing, resulting in low space utilization of the dust collection component within the mite remover. Furthermore, traditional suction-type dust collection mechanisms, after drawing airflow around the mite remover using a power component, use the airflow to carry dust and mites into the dust box. Solid foreign objects are trapped in the dust box, and the airflow is discharged through the dust box's outlet. However, allergens and mites may also be re-released into the living space with the discharged airflow, leading to unsatisfactory cleaning results.

[0004] Therefore, how to improve the utilization rate of the dust collection chamber and enhance the dust removal effect of the mite remover is a technical problem that urgently needs to be solved. Utility Model Content

[0005] The problem solved by this utility model is to provide a dust cup and a mite remover, which increases the proportion of the cup cavity used as a dust collection chamber, helps to reduce dust leakage and the number of times users need to disassemble it in a short period of time, improves the user experience, and has a wide range of applications.

[0008] Optionally, it also includes an air inlet and an air outlet penetrating the bottom of the cup body cavity, the separating member being located on the air outlet, the shape of the air outlet matching the bottom shape of the separating member, the air inlet and the air outlet being coaxially arranged, and the air inlet being tangentially arranged to the separating cup body.

[0009] Optionally, the separator has several through holes, and a filter unit is provided between the separator and the air outlet.

[0010] Optionally, the separating cup body also has a sealing rib, the sealing rib and the contact surface are located on both sides of the dust discharge port, and the surface of the sealing rib is higher than the surface of the dust discharge port.

[0011] Optionally, it also includes a cup lid that matches the cup body, wherein the cup lid covers the cup body and makes sealing contact with the sealing rib.

[0012] Optionally, the rotating separator is eccentrically positioned relative to the cup body.

[0013] Optionally, the volume ratio of the separation chamber to the dust collection chamber is 1:1.6 to 1:2.

[0014] Accordingly, this utility model also provides a mite removal device, including: a dust cup as described above; and a main unit, wherein the dust cup is located on the main unit.

[0016] Optionally, the roller brush includes a roller and a plurality of brush strips located on the outer wall of the roller, the plurality of brush strips being rotatably distributed on the outer wall of the roller around the central axis of the roller.

[0017] Optionally, the brush bar includes a connecting portion connected to the roller and a striking portion connected to the connecting portion, the striking portion having a baseball bat-shaped cross-section.

[0018] Optionally, the host is provided with a handle, and the handle has an angle of 8° to 10° with the surface of the host.

[0020] Compared with the prior art, the technical solution of this utility model has the following advantages:

[0021] In the technical solution of the dust cup provided by this utility model, a rotating separator is tangentially connected to the inner wall of the cup body at the junction of the dust-throwing port and the inner wall of the cup body to form a contact surface. The radius of curvature of the rotating separator at the junction of the dust-throwing port and the inner wall of the cup body is smaller than the radius of curvature of the cup body at the junction of the dust-throwing port and the inner wall of the cup body. On the one hand, this reduces the gap between the rotating separator and the cup body, preventing dust from the dust-throwing port from clogging the dust-throwing port. On the other hand, the tangential connection between the outer wall of the rotating separator and the inner wall of the cup body improves the integration of the rotating separator and the cup body, reduces the gap between the rotating separator and the cup body, and increases the effective volume of the dust collection chamber, thereby improving the volume ratio of the dust collection chamber. Furthermore, the smaller radius of curvature of the rotating separator makes it easier for dust to be thrown out from the dust-throwing port and directly enter the dust collection chamber along the outer wall of the rotating separator, which helps to reduce dust adhesion, avoid dust backflow, and further improve the utilization rate of the dust collection chamber, thus having a wide range of applications.

[0022] Furthermore, the air inlet and the air outlet are coaxially arranged, and the air inlet is tangential to the separation cup, which helps to optimize the airflow path and improve the separation efficiency.

[0023] Furthermore, a filter unit is provided between the separator and the air outlet to further filter fine particles in the air.

[0024] Furthermore, the cup lid and the sealing rib are in sealed contact, making the separation cup body a relatively sealed space, preventing dust from leaking into the separation cup body, causing blockage of the separation components, and reducing the separation effect.

[0025] Furthermore, the eccentric arrangement of the rotating separator with respect to the cup body can optimize the airflow path and improve dust separation efficiency. Attached Figure Description

[0035] As can be seen from the background technology, the dust cup section of existing mite removal devices still needs improvement.

[0036] Through research, the inventors discovered that by utilizing a rotating separator that forms a contact surface with the inner wall of the cup at the junction of the dust-slinging port and the inner wall of the cup, the radius of curvature of the rotating separator at this junction is smaller than that of the cup at the same junction. This reduces the gap between the rotating separator and the cup, preventing dust from clogging the dust-slinging port. Furthermore, the tangential connection between the outer wall of the rotating separator and the inner wall of the cup increases the integration between them, further reducing the gap and increasing the effective volume of the dust collection chamber, thus improving its volume ratio. The smaller radius of curvature of the rotating separator also allows dust to be more easily ejected from the dust-slinging port and directly enter the dust collection chamber along its outer wall, reducing dust adhesion, preventing backflow, and further improving the utilization rate of the dust collection chamber. This design has a wide range of applications.

[0037] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0038] First, please refer to the reference. Figures 1 to 3 A dust cup 100 includes a cup body 101 and a rotating separator 102.

[0039] The cup body 101 has a cup body cavity 101a, and the rotating separator 102 is located inside the cup body cavity 101a. The cup body cavity 101a between the rotating separator 102 and the cup body 101 is a dust collection cavity 103. The rotating separator 102 has a dust ejection port 104. At the junction 110 of the dust ejection port 104 and the inner wall of the cup body 101, the outer wall of the rotating separator 102 is internally tangentially connected to the inner wall of the cup body 101 to form a contact surface 105. The radius of curvature of the rotating separator 102 at the junction of the dust ejection port 104 and the inner wall of the cup body 101 is smaller than the radius of curvature of the cup body 101 at the junction of the dust ejection port 104 and the inner wall of the cup body 101.

[0040] In this embodiment, the rotating separator 102 forms a contact surface 105 at the junction 110 of the dust-throwing port 104 and the inner wall of the cup 101. The radius of curvature of the rotating separator 102 at the junction of the dust-throwing port 104 and the inner wall of the cup is smaller than the radius of curvature of the cup at the junction of the dust-throwing port and the inner wall of the cup. This reduces the gap between the rotating separator and the cup, preventing dust from clogging the dust-throwing port. Furthermore, the tangential connection between the outer wall of the rotating separator and the inner wall of the cup improves the integration between the rotating separator and the cup, reduces the gap between them, and increases the effective volume of the dust collection chamber, thereby improving the volume ratio of the dust collection chamber. The smaller radius of curvature of the rotating separator also makes it easier for dust to be thrown out from the dust-throwing port and directly enter the dust collection chamber along the outer wall of the rotating separator, which helps reduce dust adhesion, prevents dust backflow, and further improves the utilization rate of the dust collection chamber, thus having a wide range of applications.

[0041] In this embodiment, please refer to Figure 8 The symmetry line of the cup body 101 is L2, and the symmetry line of the rotating separator 102 is L1. The cup body 101 and the rotating separator 102 on one side of the symmetry line L2 are in complete contact to form the contact surface 105, which largely eliminates the gap between the cup body 101 and the rotating separator 102.

[0042] In this embodiment, in addition to the contact surface 105, there is a gap between the outer surface of the rotating separator 102 and the inner wall of the cup body 101, which serves as a dust collection chamber 103.

[0043] In some embodiments, please refer to Figure 9 The contact surface 105 may also be the contact surface corresponding to the junction 110.

[0044] In this embodiment, the rotating separator 102 includes a separator cup 102a and a separator 102b. The separator cup 102a has a separator cavity 102c, and the separator 102b is located in the separator cavity 102c. The separator 102b can rotate around a first rotation direction (the direction of the arrow on the separator 102b in the figure). The dust ejection port 104 extends from the point 110 that contacts the inner wall of the cup 101 along the first rotation direction.

[0045] In this embodiment, please refer to the reference. Figure 1 and Figure 8 The cross-sectional shape of the separating cup 102a is circular, thereby ensuring better centrifugal force.

[0046] In some embodiments, the cross-sectional shape of the separating cup 102a may also be elliptical, etc.

[0047] In this embodiment, the volume ratio of the separation chamber 102c to the dust collection chamber 103 is 1:1.6 to 1:2.

[0048] In this embodiment, please refer to Figure 3 It also includes an air inlet 106 and an air outlet 107 penetrating the bottom of the cup cavity 101a. The separator 102b is located on the air outlet 107. The shape of the air outlet 107 matches the bottom shape of the separator 102b. The air inlet 106 and the air outlet 107 are coaxially arranged. The air inlet 106 is tangential to the separator cup 102a, which helps to optimize the airflow path and improve the separation efficiency.

[0049] In this embodiment, the separator 102b has several through holes 102d, and a filter unit (not shown in the figure) is provided between the separator 102b and the air outlet 107.

[0050] In this embodiment, the through hole 102d is used to separate larger dust particles, while the filter unit is used to further filter fine particles in the air, thereby further improving the dust removal effect.

[0051] In this embodiment, please refer to Figure 1 The separating cup body 102a also has a sealing rib 108, the sealing rib 108 and the contact surface 105 are located on both sides of the dust discharge port 104, and the surface of the sealing rib 108 is higher than the surface of the dust discharge port 104.

[0052] In this embodiment, a cup lid 109 that matches the cup body 101 is also included (see below). Figure 4After the cup lid 109 covers the cup body 101, the cup lid 109 and the sealing rib 108 make a sealing contact, so that the separation cup body forms a relatively sealed space, preventing dust from leaking into the separation cup body, causing blockage of the separation component and reducing the separation effect.

[0053] In this embodiment, after the cup lid 109 is placed on the cup body 101, the separating cup body 102a and the cup lid 109 form a channel at the dust-throwing port 104. Air containing dust enters the rotating separating member 102 from the air inlet 106. Under the action of centrifugal force of the separating member 102b, the dust is thrown out from the dust-throwing port 104 around the first rotation direction and deposited in the dust collection chamber 103. The air separated from the dust first passes through the through hole 102d on the separating member 102b and the filter unit before being discharged from the air outlet 107. Since the gap between the rotating separating member 102 and the cup body 101 is eliminated in the opposite direction of dust movement, not only can the dust separation effect be improved, but the proportion of the cup body cavity 101a used as the dust collection chamber 103 is also increased. This helps to reduce dust leakage and the number of times the user disassembles the cup body in a short period of time, thus improving the user experience and having a wide range of applications.

[0054] In this embodiment, the rotating separator 102 is eccentrically positioned relative to the cup body 101. This eccentric positioning allows the rotating separator 102 to generate an asymmetrical centrifugal force field during rotation. This centrifugal force field can more effectively push the liquid or particles in the cup body to move in a specific direction, thereby accelerating the separation speed and helping to break up eddies and stagnant areas in the dust, allowing for more thorough separation between the dust and the air.

[0055] Accordingly, please refer to Figure 4 The present invention also provides a mite removal device 200, including the dust cup 100 described above; and a main unit 201, wherein the dust cup 100 is located on the main unit 201.

[0056] In this embodiment, since the dust cup 100 utilizes the rotating separator 102 to form a contact surface 105 at the junction 110 of the dust outlet 104 and the inner wall of the cup body 101, which is tangentially connected to form a contact surface 105, the radius of curvature of the rotating separator 102 at the junction of the dust outlet 104 and the inner wall of the cup body is smaller than the radius of curvature of the cup body at the junction of the dust outlet and the inner wall of the cup body. This reduces the gap between the rotating separator and the cup body, preventing dust from the dust outlet from clogging the dust outlet. Furthermore, the outer wall of the rotating separator and the inner wall of the cup body... The internal connection improves the integration of the rotating separator and the cup body, reduces the gap between them, and increases the effective volume of the dust collection chamber, thereby improving its volume ratio. Furthermore, the smaller radius of curvature of the rotating separator allows dust to be more easily ejected from the dust outlet and directly enter the dust collection chamber along its outer wall, helping to reduce dust adhesion, prevent backflow, and further improve the utilization rate of the dust collection chamber. This enhances the dust removal effect of the mite remover and user comfort, resulting in a wider range of applications.

[0057] In this embodiment, the host 201 includes a vacuum motor (not shown in the figure) for generating negative pressure airflow and a roller brush 202 motor (not shown in the figure) for driving the roller brush 202 to rotate. The speed range of the vacuum motor is 38,700 RPM to 473,000 RPM, and the speed range of the roller brush 202 motor is 8,640 RPM to 10,560 RPM.

[0058] In this embodiment, please refer to Figure 5 The roller brush 202 includes a roller 202a and a plurality of brush strips 202b located on the outer wall of the roller 202a. The plurality of brush strips 202b are rotatably distributed on the outer wall of the roller 202a around the central axis of the roller 202a.

[0059] In this embodiment, please refer to Figure 6 The brush bar 202b includes a connecting part 202b-2 connected to the roller 202a and a slapping part 202b-1 connected to the connecting part 202b-2. The cross-section of the slapping part 202b-1 is shaped like a baseball bat.

[0060] In this embodiment, the cross-section of the slapping part 202b-1 is shaped like a baseball bat, which helps to provide a larger slapping area, thereby making it easier to slap the fabric and improve the dust removal effect of the fabric.

[0061] In this embodiment, multiple brush strips 202b are distributed around the central axis of the roller 202a on the outer wall of the roller 202a, which helps to form a more uniform beating force, thereby reducing damage to the fabric.

[0062] In this embodiment, please refer to Figure 7 The main unit 201 is provided with a handle 203, and the handle 203 has an inclination angle α of 8° to 10° with the surface of the main unit 201. This angle is more in line with ergonomic design and helps to improve user satisfaction.

[0063] In this embodiment, please refer to Figure 4 The main unit 201 also has a button 204 for controlling the opening and closing of the vacuum motor and the roller brush 202 motor, and the button is located on the handle 203.

[0064] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
