[0002] This application claims priority to the Chinese patent application with application number 202421164496.1, entitled “Mite Removal Device”, filed with the State Intellectual Property Office of China on May 24, 2024, and the Chinese patent application with application number 202323325036.0, entitled “Cleaning Device”, filed with the State Intellectual Property Office of China on December 6, 2023, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present disclosure relates to the technical field of cleaning equipment, and in particular to a mite removal device. Background Art

[0004] A mite remover is a common household appliance designed to remove dust, bacteria, mites, and other allergens from textiles like beds, sofas, and carpets. When the user uses the mite remover, it comes into contact with the dusty surface being cleaned, and the fan draws the dust, bacteria, mites, and other allergens into the device's housing and into the dust cup.

[0005] In the related technology, the existing mite removal devices have low mite removal efficiency and poor dust removal effect. Specifically, there are the following problems: although the traditional single-motor dual-drum design can improve cleaning efficiency and coverage, the power distribution of the two drums driven by a single motor is not as balanced as the dual-motor design, and in some cases, this may lead to insufficient drum speed or torque, affecting the mite removal effect; the single motor bears double workload, which may accelerate the wear of the motor and reduce its long-term durability, thereby increasing the cost and frequency of maintenance or replacement; although the dual drum increases the cleaning contact area, if the motor power is insufficient, it may not be able to fully drive the two drums for deep cleaning, especially when facing thicker or dirtier fabric surfaces, the mite removal effect may not be as good as the dual-motor configuration equipment; when the single-motor driven dual drum encounters surfaces of different materials or thicknesses, the adjustment ability may be limited because the power of each drum cannot be adjusted independently, which may affect the cleaning adaptability on different household items.

[0048] Embodiments of the present disclosure are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0049] The following describes the mite removal device 100 according to an embodiment of the present disclosure with reference to Figures 1 to 8. It can achieve the effect of dual motors separately driving the first agitator element 5 and the second agitator element 6, and can save vertical space within the main body 1, thereby improving the dust removal and mite removal effect and space compactness.

[0050] As shown in Figures 1 to 8, the mite removal device 100 according to the first embodiment of the present disclosure includes a main body 1, a dust cup 2, a first drive motor 3, a second drive motor 4, a first agitator element 5 and a second agitator element 6.

[0051] Among them, the main body 1 mainly serves as a structural part of the outline of the mite remover 100, playing a supporting and protective role; the dust cup 2 is detachably mounted on the main body 1 to collect mites, dust, hair, etc. brushed up by the first agitator element 5 and the second agitator element 6, and filter the gas and discharge it; the first drive motor 3 and the second drive motor 4 can provide stirring driving force to the first agitator element 5 and the second agitator element 6 respectively; the first agitator element 5 and the second agitator element 6 can scrape the dust and hair adhered to the surface to be cleaned.

[0052] Specifically, the main body 1 defines a stirrer chamber 11 having a suction port 111 and an exhaust port 112. The dust cup 2 is disposed on the main body 1 and communicates with the exhaust port 112. One end of the first stirrer element 5 is in transmission connection with the first drive motor 3, and one end of the second stirrer element 6 is in transmission connection with the second drive motor 4. The first stirrer element 5 and the second stirrer element 6 are disposed within the stirrer chamber 11 and are disposed opposite each other in the transverse direction of the mite removal device 100.

[0053] Furthermore, at least portions of the first and second agitator elements 5, 6 engage the surface to be cleaned through a suction port 111. The dust cup 2 is provided with an exhaust port 112 that communicates with the agitator chamber 11. During the cleaning process, the first and second agitator elements 5, 6 pick up dirt and hair from the surface to be cleaned and guide them to the exhaust port 112. The dirt and hair are then transported to the dust cup 2 through the suction duct, thereby achieving the effect of dust removal and mite removal.

[0054] Furthermore, the first drive motor 3 and the second drive motor 4 are respectively connected to one end of the first agitator element 5 and one end of the second agitator element 6 in a transmission manner, so that the first drive motor 3 and the second drive motor 4 can respectively drive the first agitator element 5 and the second agitator element 6 to remove dust and mites. Such an arrangement can achieve the stirring of the first agitator element 5 and the second agitator element 6 at different speeds and in different directions at the same time, and can also achieve the situation where only one agitator element is stirred at the same time while the other agitator element remains stationary, thereby effectively increasing the dust removal and mite removal scenarios of the mite removal device 100.

[0055] In addition, compared to a single-drum mite removal device (i.e., a mite removal device having only one agitator element and one drive motor), the embodiments of the present disclosure can effectively increase the use scenarios of the mite removal device 100 and improve the supply of dust removal power. Compared to a single-motor mite removal device in which the agitator elements are arranged side by side in the longitudinal direction (i.e., the front-to-back direction), the embodiments of the present disclosure can independently control the first agitator element 5 and the second agitator element 6 for dust removal, and the first agitator element 5 and the second agitator element 6 are arranged relative to each other in the transverse direction (i.e., the left-right direction). This can save longitudinal installation space, improve the spatial compactness of the overall structure, and improve the efficiency of dust collection and mite removal.

[0056] Therefore, by setting up the mite removal device 100, it can achieve the effect of dual motors driving the first agitator element 5 and the second agitator element 6 separately, and can save the longitudinal space in the main body 1, thereby improving the dust removal and mite removal effect and space compactness.

[0057] According to some optional embodiments of the present disclosure, in combination with Figures 3, 5 and 7, compared with one end of the first agitator element 5, the other end of the first agitator element 5 is closer to the second agitator element 6; compared with one end of the second agitator element 6, the other end of the second agitator element 6 is closer to the first agitator element 5.

[0058] Specifically, the first agitator element 5 and the second agitator element 6 are respectively used to be connected to the first drive motor 3 and the second drive motor 4 at the ends away from each other to provide the required stirring power, which can facilitate the connection between the agitator elements and the corresponding drive motors and can easily arrange the corresponding drive motors around the agitator elements. The first agitator element 5 and the second agitator element 6 are respectively extended toward the middle of the main body 1 at the ends facing each other, which can increase the stirring coverage area of ​​the mite removal device 100 in the lateral direction, thereby ensuring the dust removal and mite removal effect of the mite removal device 100.

[0059] Optionally, in combination with what is shown in FIG3 , the first agitator element 5 and the second agitator element 6 are symmetrically arranged about the median vertical plane perpendicular to the horizontal direction of the mite removal device 100. Such an arrangement can improve the uniformity of the stirring action of the mite removal device 100 on both sides along the horizontal direction when it is working, avoid the problem of uneven dust collection and mite removal effect on the cleaning surface, and also make the structure inside the main body 1 more regular and orderly, which is convenient for improving processing and manufacturability.

[0060] According to some optional embodiments of the present disclosure, in combination with Figure 3, the central axis of the first agitator element 5 and the central axis of the second agitator element 6 are both inclined relative to the bottom surface of the mite removal device 100, and compared with one end of the first agitator element 5 and one end of the second agitator element 6, the other end of the first agitator element 5 and the other end of the second agitator element 6 are closer to the bottom surface of the mite removal device 100.

[0061] Among them, the central axis of the first agitator element 5 is inclined from one end to the other end toward the bottom surface of the mite removal device 100, and the central axis of the second agitator element 6 is inclined from one end to the other end relative to the bottom surface of the mite removal device 100, so that the first agitator element 5 and the second agitator element 6 are constructed with a double-conical structure from the bottom surface. When the inclined first agitator element 5 and the second agitator element 6 are wound around the hair during work, the hair forms a component force along the inclined surface, and the height distance of the hair at different sections in the transverse direction of the agitator element is different, so that the hair is less likely to accumulate into continuous bundles and wrap around the agitator element, thereby solving the problem of hair entanglement on the first agitator element 5 and the second agitator element 6.

[0062] Specifically, the angle between the central axis of the first agitator element 5 and the bottom surface of the mite remover 100 is α1, and α1 satisfies: 0°<α1≤15°; and / or the angle between the central axis of the second agitator element 6 and the bottom surface of the mite remover 100 is α2, and α2 satisfies: 0°<α2≤15°.

[0063] For example, the angle α1 between the central axis of the first agitator element 5 and the bottom surface of the mite removal device 100 is relatively small. This ensures that the first agitator element 5 contacts the cleaning surface while also solving the problem of hair entanglement on the first agitator element 5. For example, α1 can be 5°, 8°, 10°, or 15°, but is not limited thereto.

[0064] For example, the angle α2 between the central axis of the second agitator element 6 and the bottom surface of the mite removal device 100 is relatively small. This ensures that the second agitator element 6 contacts the cleaning surface while also solving the problem of hair entanglement on the second agitator element 6. For example, α1 can be 5°, 8°, 10°, or 15°, but is not limited thereto.

[0065] Further, in combination with Figures 3, 5 and 7, the central axis of the first agitator element 5 is parallel to the central axis of the first drive motor 3; and / or the central axis of the second agitator element 6 is parallel to the central axis of the second drive motor 4.

[0066] For example, the central axis of the first agitator element 5 is parallel to the central axis of the first drive motor 3. Such an arrangement can ensure the smoothness, efficiency and reduced wear when transmitting power. Among them, the parallel transmission center axis can ensure that power (torque) is smoothly transmitted from one axis to another, reducing energy loss caused by angular deviation and improving the efficiency of power transmission; the structure of the non-parallel transmission center axis is prone to additional vibration and impact force during operation due to the angular difference between the axes, which will not only increase mechanical wear, but also generate greater noise. The parallel setting can significantly reduce these adverse effects, making the equipment run more smoothly and quietly. The layout of the parallel transmission center axis is relatively simple, easy to design, install and maintain, and the structure of the parallel transmission center axis can reduce unnecessary friction and stress concentration, which can extend the service life of each component in the transmission system.

[0067] For another example, the central axis of the second agitator element 6 is parallel to the central axis of the second drive motor 4. Such an arrangement can ensure the smoothness, efficiency and reduced wear when transmitting power. Among them, the parallel transmission center axis can ensure that power (torque) is smoothly transmitted from one shaft to another, reducing energy loss caused by angular deviation and improving the efficiency of power transmission; the structure of the non-parallel transmission center axis is prone to additional vibration and impact force during operation due to the angular difference between the shafts, which not only increases mechanical wear, but also produces greater noise. The parallel setting can significantly reduce these adverse effects, making the equipment run more smoothly and quietly. The layout of the parallel transmission center axis is relatively simple, easy to design, install and maintain, and the structure of the parallel transmission center axis can reduce unnecessary friction and stress concentration, which can extend the service life of each component in the transmission system.

[0068] Specifically, as shown in FIG3 , the main body 1 is provided with a first mounting plate 12 and a second mounting plate 13, the first mounting plate 12 and the second mounting plate 13 are spaced apart, the first drive motor 3 is provided at the top of the first mounting plate 12 and the top of the second mounting plate 13, the top of the first mounting plate 12 is lower than the top of the second mounting plate 13, so that the central axis of the first drive motor 3 is tilted relative to the bottom surface of the mite removal device 100. The main body 1 is provided with a third mounting plate 14 and a fourth mounting plate 15, the third mounting plate 14 and the fourth mounting plate 15 are spaced apart, the second drive motor 4 is provided at the top of the third mounting plate 14 and the top of the fourth mounting plate 15, the top of the third mounting plate 14 is lower than the top of the fourth mounting plate 15, so that the central axis of the second drive motor 4 is tilted relative to the bottom surface of the mite removal device 100.

[0069] For example, the first mounting plate 12 and the second mounting plate 13 are arranged at intervals in the transverse direction, which can facilitate the support and installation of the first drive motor 3. The first mounting plate 12 is closer to the other end of the first drive motor 3 than the second mounting plate 13, and the top of the first mounting plate 12 is lower than the top of the second mounting plate 13. In this way, the mounting surface formed by the top of the second mounting plate 13 and the first mounting plate 12 can be tilted toward the bottom surface, thereby facilitating the first drive motor 3 to be stably installed in the main body 1 in an inclined shape, and further facilitating the central axis of the first drive motor 3 and the central axis of the first agitator element 5 to form a mutually parallel relationship.

[0070] For another example, the third mounting plate 14 and the fourth mounting plate 15 are spaced apart in the transverse direction, which facilitates supporting and fixing the second drive motor 4. The third mounting plate 14 is closer to the other end of the second drive motor 4 than the fourth mounting plate 15, and the top of the third mounting plate 14 is lower than the top of the fourth mounting plate 15. This allows the mounting surface formed by the top of the fourth mounting plate 15 and the third mounting plate 14 to be tilted toward the bottom surface, thereby facilitating the second drive motor 4 to be stably installed in the main body 1 in an inclined shape, thereby facilitating the central axis of the second drive motor 4 and the central axis of the second agitator element 6 to be parallel to each other.

[0071] Optionally, the main body 1 is provided with a first motor seat, the first motor seat is formed with an inclined first mounting groove, the first drive motor 3 is installed in the first mounting groove, and the central axis of the first mounting groove is parallel to or coincides with the central axis of the first drive motor 3; and / or the main body 1 is provided with a second motor seat, the second motor seat is formed with an inclined second mounting groove, the second drive motor 4 is installed in the second mounting groove, and the central axis of the second mounting groove is parallel to or coincides with the central axis of the second drive motor 4.

[0072] For example, the first motor seat can support and install the first drive motor 3. The first mounting groove on the first motor seat extends in the horizontal direction, so that an installation space for accommodating the first drive motor 3 can be provided, and the central axis of the first mounting groove is parallel to or coincides with the central axis of the first drive motor 3. In this way, without occupying excess space in the main body 1, it can also ensure that the first drive motor 3 is stably installed in the first mounting groove in an inclined shape, thereby improving the rationality of its layout.

[0073] For another example, the second motor seat can support and install the second drive motor 4. The second mounting groove on the second motor seat extends in the horizontal direction, so that an installation space for accommodating the second drive motor 4 can be provided, and the central axis of the second mounting groove is parallel to or coincides with the central axis of the second drive motor 4. In this way, the second drive motor 4 can be stably installed in the second mounting groove in an inclined shape without occupying excess space in the main body 1, thereby improving the rationality of its layout.

[0074] According to some optional embodiments of the present disclosure, in combination with Figures 3, 5 and 7, the first agitator element 5 includes a first brush rod 51 and a first scraper bar 52, one end of the first brush rod 51 is transmission-connected to the first drive motor 3, the first scraper bar 52 is arranged on the first brush rod 51, and the first scraper bar 52 extends spirally around the axis of the first brush rod 51, and the distance from the outer edge of the first scraper bar 52 to the central axis of the first brush rod 51 decreases in the direction extending from one end of the first brush rod 51 to the other end; and / or the second agitator element 6 includes a second brush rod 61 and a second scraper bar 62, one end of the second brush rod 61 is transmission-connected to the second drive motor 4, the second scraper bar 62 is arranged on the second brush rod 61, and the second scraper bar 62 extends spirally around the axis of the second brush rod 61, and the distance from the outer edge of the second scraper bar 62 to the central axis of the second brush rod 61 decreases in the direction extending from one end of the second brush rod 61 to the other end.

[0075] For example, the first brush rod 51 can rotate around its own central axis under the driving force of the first drive motor 3, and the first scraper 52 is spirally arranged on the outer periphery of the first brush rod 51 and extends along the axial direction of the first brush rod 51. In this way, the first scraper 52 can be driven by the first brush rod 51 to rotate to stir the hair debris on the cleaning surface, and the first scraper 52 can be decomposed into an effect having an extension path along the axial and radial directions of the first brush rod 51, thereby taking into account the lateral coverage and anti-entanglement properties of the first scraper 52 (the contact point of the hair in the lateral direction of the scraper is constantly changing, so that the hair is not easily entangled in a fixed position in the radial direction to form a dead knot).

[0076] In addition, the distance from the outer edge of the first scraper 52 to the central axis of the first brush rod 51 decreases in the direction extending from one end of the first brush rod 51 to the other end, so that the area passed by the first scraper 52 during rotation is conical, which can change the rotation radius of the first scraper 52 along the axial direction of the first brush rod 51. As a result, the hair is gradually loosened due to the stirring action of the first scraper 52, which makes it easier for the hair to be sucked out under the negative pressure of the exhaust port 112, thereby solving the problem of hair entanglement.

[0077] For another example, the second brush rod 61 can rotate around its own central axis under the driving force of the second drive motor 4, and the second scraper 62 is spirally arranged on the outer periphery of the second brush rod 61 and extends along the axial direction of the second brush rod 61. In this way, the second scraper 62 can be rotated under the drive of the second brush rod 61 to stir the hair debris on the cleaning surface, and the second scraper 62 can be decomposed into an effect with an extension path along the axial and radial directions of the second brush rod 61, thereby taking into account the lateral coverage and anti-entanglement properties of the second scraper 62 (the contact point of the hair in the lateral direction of the scraper is constantly changing, so that the hair is not easily entangled in a fixed position in the radial direction to form a dead knot).

[0078] In addition, the distance from the outer edge of the second scraper 62 to the central axis of the second brush rod 61 decreases in the direction extending from one end of the second brush rod 61 to the other end, so that the area passed by the second scraper 62 during rotation is conical, so that the rotation radius of the second scraper 62 along the axial direction of the second brush rod 61 can be changed, so that the hair can be gradually loosened under the stirring action of the second scraper 62 because the rotation radius of the second scraper 62 around which the hair is scattered gradually decreases, thereby facilitating the hair to be sucked out under the negative pressure of the exhaust port 112, thereby solving the problem of hair entanglement.

[0079] According to some optional embodiments of the present disclosure, in combination with Figure 3, when the mite remover 100 applies suction to the horizontal surface, the contact line and / or contact surface formed by the lowest parts of the outer surfaces of the first agitator element 5 and the second agitator element 6 are parallel to the horizontal surface, which is conducive to the first agitator element 5 and the second agitator element 6 forming a line contact or surface contact relationship with the horizontal cleaning surface, thereby increasing the cleaning force and coverage of the first agitator element 5 and the second agitator element 6 on the hair debris on the horizontal cleaning surface, thereby improving the dust removal and mite removal cleanliness of the mite remover 100.

[0080] According to some optional embodiments of the present disclosure, in combination with Figures 3, 5-8, the mite removal device 100 also includes a first reduction mechanism 7 and a second reduction mechanism 8. The first reduction mechanism 7 is respectively connected to the first drive motor 3 and one end of the first agitator element 5, and the second reduction mechanism 8 is respectively connected to the second drive motor 4 and one end of the second agitator element 6.

[0081] Among them, the first reduction mechanism 7 and the second reduction mechanism 8 can increase the torque of the output end (the first agitator element 5 and the second agitator element 6) by reducing the rotational speed of the input end (the first drive motor 3 and the second drive motor 4), thereby providing the first agitator element 5 and the second agitator element 6 with a stronger driving force and the required torque, thereby ensuring the stirring force of the first agitator element 5 and the second agitator element 6.

[0082] Specifically, as shown in Figures 5 and 7, the first reduction mechanism 7 includes a first transmission wheel 71, a second transmission wheel 72 and a first transmission belt 73. The first transmission wheel 71 is arranged on the first drive motor 3, the second transmission wheel 72 is arranged at one end of the first agitator element 5, and the first transmission belt 73 is sleeved on the first transmission wheel 71 and the second transmission wheel 72. The first transmission wheel 71 transmits power to the second transmission wheel 72 through the first transmission belt 73.

[0083] The second reduction mechanism 8 includes a third transmission wheel 81, a fourth transmission wheel 82 and a second transmission belt 83. The third transmission wheel 81 is arranged on the second drive motor 4, the fourth transmission wheel 82 is arranged at one end of the second agitator element 6, and the second transmission belt 83 is sleeved on the third transmission wheel 81 and the fourth transmission wheel 82. The third transmission wheel 81 transmits power to the fourth transmission wheel 82 through the second transmission belt 83.

[0084] For example, the first transmission wheel 71 is smaller than the second transmission wheel 72, and the first transmission wheel 71 is equivalent to the driving wheel, and the second transmission wheel 72 is equivalent to the driven wheel. When the first transmission wheel 71 rotates, the driving force is transmitted to the second transmission wheel 72 through the first transmission belt 73. Such a transmission arrangement can ensure the accuracy of the transmission ratio between the first transmission wheel 71 and the second transmission wheel 72, and also facilitate the transmission of power between the first drive motor 3 and the first agitator element 5 (the axes of the two are parallel), thereby improving transmission reliability.

[0085] For another example, the third transmission wheel 81 is smaller than the fourth transmission wheel 82, and the third transmission wheel 81 is equivalent to the driving wheel, and the fourth transmission wheel 82 is equivalent to the driven wheel. When the third transmission wheel 81 rotates, the driving force is transmitted to the fourth transmission wheel 82 through the second transmission belt 83. Such a transmission arrangement can ensure the accuracy of the transmission ratio between the third transmission wheel 81 and the fourth transmission wheel 82, and also facilitate the transmission of power between the second drive motor 4 and the second agitator element 6 (the axes of the two are parallel), thereby improving transmission reliability.

[0086] Furthermore, in combination with Figures 3 and 5-8, the mite removal device 100 also includes a first bracket 91 and a second bracket 92. The first bracket 91 is arranged on the main body 1, the first reduction mechanism 7 is arranged on the first bracket 91, the second bracket 92 is arranged on the main body 1, and the second reduction mechanism 8 is arranged on the second bracket 92.

[0087] That is to say, the first bracket 91 can provide support and installation conditions for the first reduction mechanism 7, so that the first reduction mechanism 7 can be firmly installed at the designated position inside the main body 1; the second bracket 92 can provide support and installation conditions for the second reduction mechanism 8, so that the second reduction mechanism 8 can be firmly installed at the designated position inside the main body 1; and the first bracket 91 and the second bracket 92 can also play a role in structural protection for the first reduction mechanism 7 and the second reduction mechanism 8.

[0088] Specifically, as shown in conjunction with Figures 6 and 8 , the main body 1 is provided with a first support structure 16, and the first bracket 91 is provided with spaced first baffles 911, with the top of the first support structure 16 extending between the spaced first baffles 911. The main body 1 is provided with a second support structure 17, and the second bracket 92 is provided with spaced second baffles 921, with the top of the second support structure 17 extending between the spaced second baffles 921.

[0089] For example, the first support structure 16 in the main body 1 extends upward toward one side of the first agitator element 5, and the top limit of the first support structure 16 is fitted between the first baffles 911 extending downward from the side of the first bracket 91 toward the bottom of the mite removal device 100. This can further form a supporting effect on the first bracket 91, thereby improving the structural stability and reliability of the first bracket 91.

[0090] For example, the second support structure 17 in the main body 1 extends upward toward one side of the second agitator element 6, and the top limit of the second support structure 17 is fitted between the second baffles 921 extending downward from the second bracket 92 toward the bottom of the mite removal device 100. This can further form a supporting effect on the second bracket 92, thereby improving the structural stability and reliability of the second bracket 92.

[0091] According to some optional embodiments of the present disclosure, as shown in Figure 3, the agitator chamber 11 has opposite ends 93 and 94, one end of the first agitator element 5 and one end of the second agitator element 6 are supported at the opposite ends 93 and 94, respectively, and the other end of the first agitator element 5 and the other end of the second agitator element 6 are suspended in the agitator chamber 11.

[0092] Among them, the two ends of the agitator chamber 11 that are farthest apart in the lateral direction form opposite ends 93 and 94, and one end of the first agitator element 5 and the second agitator element 6 are respectively supported at the opposite ends 93 and 94 of the agitator chamber (that is, the fixed ends), while the other end of the first agitator element 5 and the other end of the second agitator element 6 are suspended in the agitator chamber 11 (that is, the free ends). In this way, the first agitator element 5 and the second agitator element 6 achieve a cantilever support arrangement effect (referring to a situation where a structural element (such as a beam, plate, column, etc.) extends outward from its fixed point or support point without directly obtaining support at the other end), thereby adapting to the specific movement requirements of the first agitator element 5 and the second agitator element 6 in this embodiment, solving the problem of space limitation of the agitator chamber 11, and thereby improving the rationality of the arrangement.

[0093] Specifically, as shown in Figures 2 and 3, the exhaust port 112 is arranged in the middle of the agitator chamber 11, at least part of the first agitator element 5 and the second agitator element 6 engage the surface to be cleaned through the suction port 111, and the cross-sectional area of ​​the agitator chamber 11 decreases in the direction from the two opposite ends 93 and 94 of the agitator chamber 11 toward the exhaust port 112.

[0094] That is, when the first and second agitator elements 5 and 6 begin agitating the cleaning surface, hair debris adheres to the surface through at least a portion of the first and second agitator elements 5 and 6 in the suction port 111 and is then sucked away by the suction at the exhaust port 112, thereby achieving a dust and mite removal effect. The cross-sectional area of ​​the agitator chamber 11 gradually decreases from the opposite ends 93 and 94 of the agitator chamber 11 toward the exhaust port 112. This facilitates the hair wrapped around the first and second agitator elements 5 and 6 to move closer to the exhaust port 112 in the upper middle portion of the agitator chamber 11, increasing the suction force applied to the hair, thereby improving the cleaning efficiency of dust and mite removal. Furthermore, the central location of the exhaust port 112 facilitates uniform suction of the first and second agitator elements 5 and 6 by the suction device through the exhaust port 112, thus avoiding uneven suction of the first and second agitator elements 5 and 6.

[0095] Furthermore, as shown in Figures 2 and 3, the cross section of the agitator chamber 11 perpendicular to the horizontal direction of the mite removal device 100 is semicircular or major arc shaped. Major arc means that when the central angle of a section of the arc exceeds 180 degrees of the semicircle but does not reach 360 degrees (i.e., the entire circumference), the section is defined as a major arc.

[0096] It can be understood that the cross-section of the agitator chamber 11 in the lateral direction perpendicular to the mite removal device 100 adopts a semicircular structure, which can effectively disperse the pressure and convert the vertical load into a compressive force along both sides of the structure, thereby reducing the pressure at a single force point and enhancing the overall stability and load-bearing capacity of the structure. It can also better fit the rotation range of the first agitator element 5 and the second agitator element 6, thereby improving the rationality of the layout of the agitator chamber 11.

[0097] According to some optional embodiments of the present disclosure, as shown in Figures 2 and 3, the exhaust port 112 is arranged on the middle rear side of the blender chamber 11, and the central axis of the exhaust port 112 passes through the interval space between the first blender element 5 and the second blender element 6 of the blender chamber 11.

[0098] The central axis of the exhaust port 112 of the blender chamber 11 passes through the space between the first blender element 5 and the second blender element 6. This facilitates the suction device to evenly suction the hair debris stirred by the first blender element 5 and the second blender element 6 on both sides thereof through the exhaust port 112, thereby improving the cleaning efficiency of the mite removal device 100. In addition, the exhaust port 112 is arranged at the rear side of the middle of the blender chamber 11. In this way, after the hair debris is fully stirred and attached to the outer edges of the first blender element 5 and the second blender element 6, it can be sucked out through the exhaust port 112, thereby ensuring that the mite removal device 100 can perform deep and intensive vacuuming and mite removal.
