Description

Technical Field

[0001] This application relates to the field of environmental cleaning electrical appliances, and in particular to a mite removal device. Background Technology

[0002] In existing technologies, the tapping mite remover mainly uses the high-frequency vibration of the bottom tapping block to tap the fabric, causing dust, mites and excrement hidden deep in the fabric to be shaken off, and then the negative pressure generated by the fan sucks the dirt into the dust collection box.

[0003] However, existing mite removal devices suffer from inefficient removal of dirt and high resistance to movement due to unreasonable air duct design. Utility Model Content

[0004] Based on this, this application provides a mite removal device to address the shortcomings of related technologies.

[0005] The mite removal device provided in this application includes:

[0006] The housing has a placement surface and a groove on one side. The placement surface is configured to contact the surface to be cleaned. The groove has a flow channel and a first air intake. The flow channel is located on at least one side of the first air intake along a first direction.

[0007] The airflow channel includes a first channel, a second channel, and a third channel. The two ends of the first channel are connected to the second channel and the third channel, respectively. The second channel and the third channel are arranged in parallel. The first channel and the second channel are arranged at an angle. The end of the second channel away from the first channel is connected to the first air intake.

[0008] The first direction is perpendicular to the direction of travel of the mite removal device.

[0009] The mite removal device provided in this embodiment has a placement surface on the side facing the surface to be cleaned. This allows the user to push the mite removal device across the surface after it comes into contact with it. A first air intake is located within the groove, allowing dirt on the surface to enter the device along with the airflow. A guide channel, consisting of a first channel, a second channel, and a third channel, is located to the left or right of the first air intake. This allows airflow to enter the groove from the left or right side and flow along the guide channel towards the first air intake, effectively removing dirt from both sides of the device and improving its suction efficiency. Furthermore, the guide channel guides the airflow in an orderly manner, preventing turbulence and reducing airflow resistance. This reduces the negative pressure at the bottom of the device, decreasing the adhesion between the device and the surface, making it easier for the user to push the device.

[0010] In one possible implementation, the side of the first channel closer to the second channel is tilted towards the first air intake relative to the side farther away from the second channel;

[0011] The length of the second channel is along the first direction.

[0012] Thus, since the third channel is set parallel to the second channel, the third channel can also extend along the first direction, allowing the airflow to enter the groove from the left and right sides of the mite removal device and flow towards the middle part of the mite removal device in the left and right direction. Then it flows along the first channel to continue flowing towards the middle part of the mite removal device, and then flows along the second channel to converge towards the first air intake in the left and right direction. This optimizes the airflow path, allowing the airflow to flow orderly towards the first air intake.

[0013] In one possible implementation, the mite removal device further includes a cleaning component located in a recess and movably connected to the housing, with the cleaning component and the first air intake spaced apart along the travel direction of the mite removal device.

[0014] In this way, when the user pushes the mite removal device across the surface to be cleaned, the cleaning component first taps or performs other operations on the surface to be cleaned, so that the dust mites hidden on the surface to be cleaned are fully exposed. Then, the dust mites and other dirt are sucked away through the first air inlet, thereby improving the cleaning effect of the mite removal device.

[0015] In one possible implementation, the cleaning component and the second channel are spaced apart along the travel direction of the mite removal device, and the minimum distance T between the second channel and the cleaning component satisfies: 8 mm ≤ T ≤ 10 mm.

[0016] This prevents the fabric from getting stuck between the second channel and the cleaning component after being sucked up, and improves the structural compactness of the mite removal device.

[0017] In one possible implementation, the width of the first channel increases from the end away from the second channel to the end closer to the second channel;

[0018] The second channel is set with a uniform width along its own length.

[0019] Thus, as the airflow flows sequentially along the third, first, and second channels, it naturally converges towards the first air intake, thereby optimizing the airflow, improving the dust removal effect of the mite removal device, and reducing the adhesion between the mite removal device and the surface to be cleaned.

[0020] In one possible implementation, the width W1 of the first channel satisfies: 8 mm ≤ W1 ≤ 12 mm;

[0021] And / or, the width W2 of the second channel satisfies: 8mm ≤ W1 ≤ 15mm.

[0022] This allows the first and second channels to guide the airflow toward the first air inlet in sequence, and also helps to reduce the proportion of the guide channel in the groove, thereby optimizing the structural layout within the groove.

[0023] In one possible implementation, the groove has a first guide rib and a second guide rib;

[0024] The first guide rib and the second guide rib define a first channel and a second channel, and the first guide rib and the sidewall of the groove define a third channel.

[0025] Thus, by adding a first guide rib and a second guide rib in the groove, a small structural modification can be made to the existing mite removal device to form a guide channel in the groove, which is conducive to guiding the airflow on the left and right sides of the mite removal device to flow towards the first air intake in the middle, thereby facilitating the removal of dirt on the left and right sides of the mite removal device.

[0026] In one possible implementation, the first guide rib is positioned on the front side of the mite removal device's travel direction relative to the second guide rib, with the end of the first guide rib facing the placement surface higher than the end of the second guide rib facing the placement surface.

[0027] Thus, because the first guide rib is relatively high, the side wall area of ​​the first guide rib can be increased, thereby increasing the flow area of ​​the flow channel and improving the flow effect of the flow channel. Furthermore, because the second guide rib is positioned closer to the rear side of the mite removal device than the first guide rib, and the second guide rib is relatively low, the second guide rib is prevented from hindering the movement of the mite removal device on the surface to be cleaned.

[0028] In one possible implementation, the groove includes a first groove and a second groove that are interconnected, with the second groove located on one side of the first groove along a first direction;

[0029] The first air intake and the second guide rib are located in the first groove. The first guide rib includes a first extension section, a second extension section and a third extension section connected in sequence. The first extension section extends along a first direction. One end of the first extension section is located in the second groove and the other end of the first extension section is located in the first groove. A third channel is defined between the first extension section and the sidewall of the second groove. Both the second extension section and the third extension section are located in the first groove.

[0030] The second guide rib includes a fourth extension section and a fifth extension section. The second extension section and the fourth extension section are arranged opposite to each other along the direction of travel of the mite removal device to jointly define the first channel. The third extension section and the fifth extension section are arranged opposite to each other along the direction of travel of the mite removal device to jointly define the second channel.

[0031] Thus, the first guide rib, the second guide rib, and the sidewall of the groove can together define the guide channel, and make the guide channel extend first in the left and right direction, then tilt relative to the left and right direction, and finally extend to the first air intake in the left and right direction.

[0032] In one possible implementation, the groove also has a second air inlet, with the first air inlet and the second air inlet located on opposite sides of the cleaning component along the direction of travel of the mite removal device; the first air inlet is positioned relative to the second air inlet on the rear side of the mite removal device along the direction of travel.

[0033] In this way, the first and second air inlets can effectively cover the surface to be cleaned. After the cleaning component taps the surface, the first and second air inlets can suck away the dust mites that have been raised in the first instance, thus preventing the dust mites from falling back onto the surface and improving the cleaning effect of the mite removal device. In one possible implementation, the mite removal device also includes a dust cup assembly, and the housing also has a suction channel located on the side of the groove away from the placement surface. Both the first and second air inlets are connected to the side of the suction channel near the groove.

[0034] The suction channel has an air inlet on the side opposite to the groove. The air inlet is located on the rear side of the cleaning component near the direction of travel of the mite removal device, and the air inlet is connected to the dust cup assembly.

[0035] In this way, when the cleaning component taps the surface to be cleaned, the dust mites are fully exposed under the vibration. The first and second air inlets can quickly suck up the dust mites. The airflow entering from the second air inlet can flow backward along the airflow channel and converge with the airflow entering from the first air inlet. Then, it enters the dust cup assembly through the air inlet, thereby collecting the dust mites in the dust cup assembly. Throughout the entire dust removal process, the airflow flows in an orderly manner with low flow resistance, which can improve the dust removal effect of the mite removal device and reduce the negative pressure at the bottom of the mite removal device.

The embodiments of this application will be described in detail below with reference to the accompanying drawings.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0048] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0049] In existing technologies, the tapping mite remover mainly uses the high-frequency vibration of the bottom tapping block to tap the fabric, causing dust, mites and excrement hidden deep in the fabric to be shaken off, and then the negative pressure generated by the fan sucks the dirt into the dust collection box.

[0050] However, existing mite removers have the following problems: First, their dirt suction efficiency is insufficient. This is due to an unreasonable air duct design. When airflow enters from the bottom air inlet, dust on both sides tends to accumulate in the edge areas, failing to effectively concentrate at the central air inlet, resulting in some dirt residue and affecting the cleaning effect of the mite remover. Second, the mite remover has high pushing resistance. This is because the unreasonable air duct design leads to high negative pressure at the bottom of the mite remover during operation, requiring users to apply considerable force when pushing it, thus reducing the user experience.

[0051] In view of the above problems, this application provides a mite removal device. The mite removal device has a groove on the side facing the surface to be cleaned. The groove has a guide channel. The guide channel can guide the airflow on both sides of the mite removal device to flow towards the first air intake in the middle, thereby improving the dust collection effect of the mite removal device and reducing the negative pressure at the bottom of the mite removal device.

[0052] The specific implementation of the mite removal device provided in this application will be described in detail below with reference to the accompanying drawings.

[0053] Reference Figures 1 to 4As shown, the mite removal device provided in this application embodiment includes a housing 100. One side of the housing 100 has a placement surface 110 and a groove 120. The placement surface 110 is configured to contact the surface to be cleaned. The groove 120 has a guide channel 121 and a first air intake 122. The guide channel 121 is located on at least one side of the first air intake 122 along a first direction.

[0054] The flow channel 121 includes a first channel 1211, a second channel 1212 and a third channel 1213. The two ends of the first channel 1211 are connected to the second channel 1212 and the third channel 1213 respectively. The second channel 1212 and the third channel 1213 are arranged in parallel. The first channel 1211 and the second channel 1212 are arranged at an angle. The end of the second channel 1212 away from the first channel 1211 is connected to the first air intake 122.

[0055] The first direction is perpendicular to the direction of travel of the mite removal device. The first direction can be considered as the left-right direction of the mite removal device. The first direction can be referenced... Figure 1 In the X direction, the mite removal device moves along its own front-to-back direction. The direction of movement of the mite removal device can be referenced. Figure 1 Y direction.

[0056] In this embodiment, the placement surface 110 is used to contact the surface to be cleaned. The user applies force to the mite removal device to push the mite removal device to move on the surface to be cleaned, thereby causing the mite removal device to suck up dirt such as dust mites and hair from the surface to be cleaned.

[0057] Since the groove 120 is open on the side facing the surface to be cleaned, when the placement surface 110 is in contact with the surface to be cleaned, the surface to be cleaned and the groove 120 can jointly define a negative pressure zone to form a negative pressure airflow, thereby sucking away the dirt on the surface to be cleaned through the negative pressure airflow. The first air intake 122 is located on the bottom wall of the groove 120 away from the placement surface 110, which can prevent the fabric from blocking the first air intake 122.

[0058] If the guide channel 121 is not provided in the groove 120, when the negative pressure airflow enters the groove 120, it will flow randomly to the first air intake 122, which will result in poor dust removal effect of the mite removal device and high negative pressure in the groove 120, which will make it difficult for the mite removal device to move.

[0059] In this embodiment, a guide channel 121 is provided in the groove 120. The guide channel 121 includes a third channel 1213, a first channel 1211, and a second channel 1212 connected in sequence. Since the guide channel 121 is located on the left and right sides of the first air intake 122 and is connected to the first air intake 122, external air can enter the groove 120 along the left and right sides of the mite removal device, thereby forming a negative pressure airflow. The negative pressure airflow can flow along the third channel 1213, the first channel 1211, and the second channel 1212 in sequence to guide the airflow to flow orderly to the first air intake 122. In this process, the negative pressure airflow can fully remove the dirt on the left and right sides of the mite removal device, thus effectively improving the dust removal effect of the mite removal device.

[0060] Understandably, because the negative pressure airflow flows orderly along the third channel 1213, the first channel 1211, the second channel 1212 and the first air intake 122, it can reduce airflow turbulence and airflow resistance, thereby reducing the negative pressure suction at the bottom of the mite removal device. This reduces the adsorption force between the mite removal device and the surface to be cleaned, making it easier for the user to push the mite removal device and thus improving the user experience.

[0061] In practical implementation, the second channel 1212 and the third channel 1213 can be arranged in parallel, and the first channel 1211 can be arranged at an angle relative to the second channel 1212 and the third channel 1213. In this way, external air can enter the groove 120 from the left and right sides of the mite removal device, flow along the third channel 1213, then enter the first channel 1211 and change direction, and after entering the second channel 1212, change direction again to flow to the first air intake 122.

[0062] In this way, it is convenient to design the length extension direction of the guide channel 121 according to the shape of the groove 120 and the position of the first air intake 122 in the groove 120, so as to optimize the structural layout in the groove 120 and guide the airflow to flow in an orderly manner toward the first air intake 122.

[0063] The mite removal device provided in this embodiment includes a housing 100, which includes a placement surface 110 and a groove 120. The groove 120 includes a guide channel 121 and a first air intake 122. The guide channel 121 includes a first channel 1211, a second channel 1212, and a third channel 1213. Since the placement surface 110 is provided on the side of the mite removal device facing the surface to be cleaned, the user can push the mite removal device across the surface after it comes into contact with it. Because the first air intake 122 is provided in the groove 120, dirt on the surface to be cleaned can enter the interior of the mite removal device along with the airflow through the first air intake 122. Because the groove 120 is provided with a guide channel 121 consisting of a first channel 1211, a second channel 1212 and a third channel 1213, and the guide channel 121 is located on the left or right side of the first air intake 122, the airflow can enter the groove 120 from the left or right side and flow along the guide channel 121 toward the first air intake 122, thereby allowing the airflow to fully suck up the dirt on the left and right sides of the mite removal device, thereby improving the dust removal effect of the mite removal device. In addition, the guide channel 121 can guide the airflow to flow in an orderly manner, thereby preventing airflow turbulence and reducing airflow resistance, thereby reducing the negative pressure at the bottom of the mite removal device, thereby reducing the adsorption force between the mite removal device and the surface to be cleaned, thus making it easier for the user to push the mite removal device.

[0064] In some embodiments, the side of the first channel 1211 closest to the second channel 1212 is inclined toward the first air intake 122 relative to the side furthest from the second channel 1212, and the length direction of the second channel 1212 is along the first direction.

[0065] Thus, since the third channel 1213 is arranged parallel to the second channel 1212, the third channel 1213 can also extend along the first direction, thereby allowing the airflow to enter the groove 120 from the left and right sides of the mite removal device and flow towards the middle part of the mite removal device in the left and right direction, then flow along the first channel 1211 to continue flowing towards the middle part of the mite removal device, and then flow along the second channel 1212 to converge towards the first air intake 122 in the left and right direction. In this way, the airflow path can be optimized, so that the airflow flows to the first air intake 122 in an orderly manner.

[0066] Reference Figure 1 , Figure 3 , Figure 4 As shown, in one possible implementation, the mite removal device further includes a cleaning component 200, which is located in the groove 120 and is movably connected to the housing 100. The cleaning component 200 and the first air intake 122 are spaced apart along the travel direction of the mite removal device.

[0067] For example, the cleaning component 200 is positioned near the front of the mite removal device relative to the first air intake 122. When the user pushes the mite removal device to walk on the surface to be cleaned, the cleaning component 200 first performs operations such as patting on the surface to be cleaned to fully expose the dust mites hidden on the surface to be cleaned, and then sucks away the dust mites and other dirt through the first air intake 122, thereby improving the cleaning effect of the mite removal device.

[0068] Alternatively, the first air intake 122 is positioned relative to the front of the cleaning component 200 near the mite removal device. The cleaning component 200 can perform operations such as patting and sweeping dust on the surface to be cleaned. At the same time, airflow enters the mite removal device from the first air intake 122. The two work together to improve the cleaning effect of the mite removal device.

[0069] In some embodiments, the cleaning component 200 and the second channel 1212 are spaced apart along the travel direction of the mite removal device, and the minimum distance T between the second channel 1212 and the cleaning component 200 satisfies: 8 mm ≤ T ≤ 10 mm.

[0070] Understandably, when the mite removal device moves across the surface to be cleaned, since the surface to be cleaned is mainly made of fibrous fabric, the fabric is relatively soft and easily sucked up by the suction of the mite removal device. On the one hand, in order to prevent the fabric from being sucked up and blocking the second channel 1212 and the cleaning component 200, the minimum distance T between the second channel 1212 and the cleaning component 200 needs to be greater than or equal to 8 mm. On the other hand, the minimum distance T between the second channel 1212 and the cleaning component 200 needs to be less than or equal to 10 mm to improve the structural compactness of the mite removal device.

[0071] For example, the minimum spacing T between the second channel 1212 and the cleaning component 200 can be 8 mm, 8.5 mm, 9 mm or 10 mm, etc.

[0072] In one possible implementation, the width of the first channel 1211 gradually increases from the end away from the second channel 1212 to the end closer to the second channel 1212, and the second channel 1212 is set with a uniform width along its own length direction.

[0073] In other words, the first channel 1211 can be funnel-shaped, with the smaller diameter end of the first channel 1211 facing away from the second channel 1212 and the larger diameter end of the first channel 1211 facing the second channel 1212. In this way, when the airflow flows sequentially along the third channel 1213, the first channel 1211, and the second channel 1212, the airflow can naturally converge towards the first air intake 122, thereby optimizing the airflow, improving the dust removal effect of the mite removal device, and reducing the adsorption force between the mite removal device and the surface to be cleaned.

[0074] In one possible implementation, the width W1 of the first channel 1211 satisfies: 8 mm ≤ W1 ≤ 12 mm. And / or, the width W2 of the second channel 1212 satisfies: 8 mm ≤ W1 ≤ 15 mm.

[0075] It should be noted that, on the one hand, if the width W1 of the first channel 1211 is less than 8 mm and the width W2 of the second channel 1212 is less than 8 mm, the widths of the first channel 1211 and the second channel 1212 are relatively small, which is not conducive to guiding the airflow of the first channel 1211 and the second channel 1212, thus making it difficult to optimize the airflow path. On the other hand, if the width W1 of the first channel 1211 is greater than 12 mm and the width W2 of the second channel 1212 is greater than 15 mm, the proportion of the guide channel 121 in the groove 120 will be relatively large, which is not conducive to arranging the first air intake 122, the cleaning component 200 and other structures in the groove 120.

[0076] Therefore, the width W1 of the first channel 1211 is between 8 mm and 12 mm, and the width W2 of the second channel 1212 is between 8 mm and 15 mm. This is beneficial for the first channel 1211 and the second channel 1212 to guide the airflow toward the first air intake 122 in sequence, and it is also beneficial to reduce the proportion of the guide channel 121 in the groove 120, thereby optimizing the structural layout in the groove 120.

[0077] In some embodiments, the groove 120 has a first guide rib 123, and the first guide rib 123 defines a guide channel 121 between the sidewall of the groove 120 and the sidewall of the groove 120.

[0078] Reference Figure 2 , Figure 4 As shown, in some embodiments, the groove 120 has a first guide rib 123 and a second guide rib 124, with a first channel 1211 and a second channel 1212 defined between the first guide rib 123 and the second guide rib 124, and a third channel 1213 defined between the first guide rib 123 and the sidewall of the groove 120.

[0079] Thus, by adding the first guide rib 123 and the second guide rib 124 in the groove 120, a small structural modification can be made to the existing mite removal device to form a guide channel 121 in the groove 120, which is conducive to guiding the airflow on the left and right sides of the mite removal device to flow towards the first air intake 122 in the middle, thereby facilitating the removal of dirt on the left and right sides of the mite removal device.

[0080] In one possible implementation, the first guide rib 123 is positioned on the front side of the second guide rib 124 near the direction of travel of the mite removal device, and the end of the first guide rib 123 facing the placement surface 110 is higher than the end of the second guide rib 124 facing the placement surface 110.

[0081] In this way, since the first guide rib 123 is relatively high, the side wall area of ​​the first guide rib 123 can be increased, thereby increasing the guide area of ​​the guide channel 121 and improving the guide effect of the guide channel 121. Furthermore, since the second guide rib 124 is positioned closer to the rear side of the mite removal device than the first guide rib 123, and the second guide rib 124 is relatively low, the second guide rib 124 is prevented from hindering the movement of the mite removal device on the surface to be cleaned.

[0082] Reference Figure 1 , Figure 2 As shown, in a specific implementation, the groove 120 includes a first groove 120a and a second groove 120b that are interconnected, with the second groove 120b located on one side of the first groove 120a along the first direction.

[0083] The first air intake 122 and the second guide rib 124 are located in the first groove 120a. The first guide rib 123 includes a first extension 1231, a second extension 1232 and a third extension 1233 connected in sequence. The first extension 1231 extends along a first direction. One end of the first extension 1231 is located in the second groove 120b and the other end of the first extension 1231 is located in the first groove 120a. A third channel 1213 is defined between the first extension 1231 and the sidewall of the second groove 120b. The second extension 1232 and the third extension 1233 are both located in the first groove 120a.

[0084] The second guide rib 124 includes a fourth extension 1241 and a fifth extension 1242. The second extension 1232 and the fourth extension 1241 are arranged opposite to each other along the direction of travel of the mite removal device to jointly define the first channel 1211. The third extension 1233 and the fifth extension 1242 are arranged opposite to each other along the direction of travel of the mite removal device to jointly define the second channel 1212.

[0085] In other words, the first guide rib 123, the second guide rib 124, and the sidewall of the groove 120 can together define the guide channel 121, so that the guide channel 121 first extends in the left and right direction, then tilts relative to the left and right direction, and finally extends in the left and right direction to the first air intake 122. In this way, the airflow can enter from the second groove 120b and flow along the third channel 1213. After entering the first groove 120a, it flows along the first channel 1211 and the second channel 1212 to the first air intake 122 in sequence, which helps to optimize the airflow path.

[0086] Reference Figure 1 , Figure 3 , Figure 4As shown, in one possible implementation, the groove 120 also has a second air inlet 125. The first air inlet 122 and the second air inlet 125 are respectively located on both sides of the cleaning component 200 along the direction of travel of the mite removal device. The first air inlet 122 is arranged on the rear side of the mite removal device relative to the second air inlet 125.

[0087] In other words, the front and rear sides of the cleaning component 200 are respectively provided with a second air intake 125 and a first air intake 122. Compared with only providing a first air intake 122 and a second air intake 125, the combined area of ​​the first air intake 122 and the second air intake 125 is larger, which allows the first air intake 122 and the second air intake 125 to effectively cover the surface to be cleaned. When the cleaning component 200 taps the surface to be cleaned, regardless of whether the dust mites move forward or backward, the first air intake 122 and the second air intake 125 can suck away the dust mites that are raised in the first time, thereby preventing the dust mites from falling back onto the surface to be cleaned, thus improving the cleaning effect of the mite removal device.

[0088] The airflow path of the mite removal device can be referenced. Figure 1 and Figure 3 As shown by the dashed arrow.

[0089] Reference Figure 3 , Figure 4 As shown, in one possible implementation, the mite removal device also includes a dust cup assembly, and the housing 100 also has a suction channel 130 located on the side of the groove 120 away from the placement surface 110. The first suction port 122 and the second suction port 125 are both connected to the side of the suction channel 130 near the groove 120.

[0090] The suction channel 130 has an air inlet 131 on the side opposite to the groove 120. The air inlet 131 is located on the rear side of the cleaning component 200 near the direction of travel of the mite removal device, and the air inlet 131 is connected to the dust cup assembly.

[0091] With this configuration, when the cleaning component 200 taps the surface to be cleaned, the dust mites are fully exposed under the vibration. The first air intake 122 and the second air intake 125 can quickly suck up the dust mites. The airflow entering from the second air intake 125 can flow backward along the air intake channel 130 and converge with the airflow entering from the first air intake 122. Then, it enters the dust cup assembly through the air inlet 131, thereby collecting the dust mites in the dust cup assembly. During the entire dust removal process, the airflow flows in an orderly manner with low flow resistance, which can improve the dust removal effect of the mite removal device and reduce the negative pressure at the bottom of the mite removal device.
