Description

Technical Field

[0001] This invention relates to the field of home appliance technology, and in particular to a mite remover. Background Technology

[0002] Bedding, sofas, carpets, and other textiles easily accumulate dust and mites, posing a significant health risk. Therefore, mite removal devices are increasingly used. Existing mite removal devices eliminate mites through adsorption and ultraviolet light. During cleaning, ultraviolet lamps emit ultraviolet light to kill mites on the surface to be cleaned, and the bottom of the device's suction inlet contacts the surface, drawing the dust mites into the device. However, because ultraviolet light has poor penetrating power, its intensity weakens as it passes through the lamp's wall, reducing its sterilization and cleaning effectiveness. This is particularly noticeable after a period of use, when the ultraviolet lamp ages or accumulates dirt, leading to unsatisfactory mite removal results in existing devices. Summary of the Invention

[0080] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0082] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0084] The following description, in conjunction with the accompanying drawings, illustrates an embodiment of the mite removal device and its control method. It should be noted that the mite removal device in this application is used to remove allergens such as bacteria, viruses, dust, and mites that grow on textiles such as bedding, sofas, carpets, and clothing.

[0085] Figure 1 This is a schematic diagram of the structure of a mite remover provided in one embodiment of this application. Figure 2 This is an exploded structural diagram of a mite remover provided in one embodiment of this application. Figure 3 This is an exploded structural diagram of the mite remover provided in one embodiment of this application after the outer shell has been removed.

[0086] Reference Figure 1 , Figure 2 , Figure 3 The first aspect of this application provides a mite remover 100, including a housing 110 and a steam assembly 120 and a steam outlet 130 disposed on the housing 110. In some other embodiments, the mite remover 100 may further include a roller brush assembly 150 and a vacuuming assembly 160 disposed on the housing 110.

[0087] The steam assembly 120 has a steam outlet capable of outputting steam; the steam outlet 130 has a steam channel constructed inside, which is connected to the steam outlet of the steam assembly 120, and the steam channel is provided with a steam vent 131 that communicates with the outside. The steam flowing out from the steam outlet can be discharged through the steam channel and the steam vent 131; the steam vent 131 is opened towards the surface to be cleaned.

[0088] The roller brush assembly 150 includes a roller brush 151, and the housing 110 is configured with a first receiving cavity 1521. The roller brush 151 is rotatably disposed in the first receiving cavity 1521, and the roller brush 151 can roll into contact with the surface to be cleaned.

[0089] The vacuuming assembly 160 has a vacuum port communicating with the first receiving cavity 1521, which is used to suck in dust mites brought up by the roller brush 151 rolling into contact with the surface to be cleaned.

[0090] In the above solution, by setting up a steam assembly 120 and a steam outlet 130, the steam flowing from the steam outlet of the steam assembly 120 can be discharged from the steam vent 131 to remove mites from the surface to be cleaned. The high-temperature steam can penetrate into the fabric through the tiny gaps and holes between the textiles to perform deep sterilization and mite removal, and can also easily decompose stains, resulting in good mite removal and sterilization effects. On the other hand, by setting up a roller brush assembly 150 and a vacuum assembly 160, when the roller brush 151 rolls into contact with the surface to be cleaned, it can beat the surface to be cleaned, lifting up dust, mites, and other allergens from the inside and surface of the textiles, which are then sucked away through the vacuum port of the vacuum assembly 160, resulting in even better mite removal effects on the textiles.

[0091] In some embodiments, the mite remover 100 may further include a drying component 180, which generates hot air to dehumidify and dry textiles, and kill mites, bacteria and other pests in the textiles.

[0092] In some embodiments, the mite remover 100 may further include an ultraviolet sterilization unit 142 and a buzzer 141, wherein the ultraviolet sterilization unit 142 kills mites in textiles by emitting ultraviolet light; and the buzzer 141 is capable of emitting mite-removing ultrasonic waves to remove mites.

[0093] Thus, the mite remover 100 of this embodiment utilizes steam to penetrate deep into the fabric to remove mites, and uses a buzzer 141 to emit ultrasonic waves to assist in killing mites inside the fabric. Combined with a drying component 180, the surface to be cleaned is baked at high temperature to further remove mites. On the other hand, a roller brush 151 is used to beat the surface of the fabric to be cleaned, which can lift up the killed mites and dust, and the suction component 160 is used to absorb and remove the lifted dust mites. By combining multiple methods for mite removal, the mite removal effect is better.

[0094] Understandably, for ease of explanation, the side of the mite remover 100 that faces (or contacts) the surface to be cleaned is defined as the bottom side of the mite remover 100, and the side of the mite remover 100 that faces away from the bottom side is defined as the top side. The direction from the bottom side to the top side is defined as the Z direction. Furthermore, the direction of travel of the mite remover 100 in its operating state is defined as the X direction, also known as the first direction X, and the direction perpendicular to both the X and Z directions is defined as the Y direction.

[0095] Reference Figure 1 , Figure 2 The outer casing 110 has a receiving cavity 1101. The outer casing 110 may include a bottom shell 111 that covers the bottom shell 111 and a top shell 112 that is disposed opposite to the bottom shell 111. The bottom shell 111 and the top shell 112 together define the receiving cavity 1101.

[0096] The following description, in conjunction with the accompanying drawings, details the structure of the mite remover 100, including the steam assembly 120, steam outlet 130, roller brush assembly 150, dust suction assembly 160, drying assembly 180, ultraviolet sterilization unit 142, and buzzer 141.

[0097] [Steam Components]

[0098] Reference Figure 2 , Figure 3 The steam assembly 120 includes a water tank 122 and a heating element 121 disposed in the receiving cavity 1101. The heating element 121 is used to convert the water provided by the water tank 122 into steam. The steam here can generally reach above 105°C, which has a better sterilization and mite removal effect. For example, the heating element 121 can be a boiler, or a heating device such as a heating wire or a thick film heating element.

[0099] The water tank 122, the heating element 121, and the roller brush assembly 150 are arranged sequentially in the first direction X. Placing the roller brush assembly 150, which generates vibration and tapping motions, at the end of the mite remover 100 can reduce the impact of the roller brush assembly 150 on other components.

[0100] It is understood that the device used to generate steam here includes, but is not limited to, the heating element 121, and may also be a superconductor, etc.

[0101] The water tank 122 has a water storage cavity and an outlet. In some embodiments, the water tank 122 includes a connecting pipe 171 and a gravity ball 172. The gravity ball 172 has a liquid channel, and the two ends of the connecting pipe 171 are connected to the liquid channel of the gravity ball 172 and the outlet of the water tank 122, respectively. Regardless of the orientation of the mite remover 100, the gravity ball 172 can always be located at the bottom of the water tank 122 in the direction of gravity. When there is suction at the outlet of the water tank 122, the water in the water tank 122 can be drawn to the outlet through the gravity ball 172. In this way, the mite remover 100 can clean horizontal surfaces such as beds, or it can be used as a garment steamer for ironing on vertical surfaces.

[0102] In this embodiment, the steam assembly 120 further includes a detection sensor 124, which detects the water level in the water tank 122. When the water level in the water tank 122 is lower than a preset value, an alarm can be triggered by an alarm unit. The alarm unit may be, for example, a buzzer or an alarm light.

[0103] Figure 4 This is a schematic diagram of a portion of the structure of a mite remover after the outer shell has been removed, according to an embodiment of this application.

[0104] Reference Figure 4 The heating element 121 can be electrically heated to convert water into steam.

[0105] The heating element 121 may include an inlet 1211 and an outlet 1212. The inlet 1211 is connected to the outlet of the water tank 122, and the outlet 1212 is used to discharge the steam generated in the heating element 121. The height of the inlet 1211 relative to the bottom end face of the outer casing 110 is lower than the height of the outlet 1212 relative to the bottom end face of the outer casing 110. This prevents water in the heating element 121 from flowing out of the outlet before it is fully vaporized due to gravity.

[0106] In practice, based on the posture of the mite remover 100 in use, the inlet 1211 of the heating element can be set at the bottom of the heating element 121, and the outlet 1212 of the heating element can be set at the top of the heating element 121.

[0107] For example, the angle β between the surface of the heating element 121 facing the bottom of the outer casing 110 and the bottom end face of the outer casing 110 is 10° to 40°. This allows the water in the heating element 121 to vaporize as much as possible. Preferably, when the angle β between the surface of the heating element 121 facing the bottom of the outer casing 110 and the bottom end face of the outer casing 110 is 15° to 30°, the steam output at the outlet of the heating element 121 can be maximized when water enters through the inlet 1211 of the heating element and steam exits through the outlet 1212 of the heating element.

[0108] In some examples, see below. Figure 14 The heating element 121 may include a heating element body 1214 and a heating element shell 1215 covering the outside of the heating element body 1214. A second heating cavity 1213 is defined between the outer surface of the heating element body 1214 and the heating element shell 1215. The second heating cavity 1213 can generate hot air for drying the surface to be cleaned. The temperature of the hot air may be, for example, 60°C.

[0109] In this embodiment, reference continues to be made to... Figure 3 The steam assembly 120 also includes a drive pump 123. The outlet of the drive pump 123 is connected to the inlet 1211 of the heating element, and the inlet of the drive pump 123 is connected to the outlet of the water tank 122. The outlet 1212 of the heating element is connected to the steam inlet 132 of the steam outlet 130. The heating element 121 can be used to convert the water pumped by the drive pump 123 into steam. For example, a solenoid valve or similar device can also be connected between the outlet of the water tank 122 and the inlet of the drive pump 123.

[0110] [Steam Exit Components]

[0111] Figure 5 This is a schematic diagram of the steam outlet component in a mite remover provided in one embodiment of this application. Figure 6 This is an exploded structural diagram of a mite remover provided in one embodiment of this application from another angle. Figure 7 for Figure 6 A magnified view of a portion at point A.

[0112] Reference Figure 5 , Figure 6 As mentioned above, the steam outlet 130 has a steam channel that is connected to the steam outlet of the steam assembly 120. The steam channel is provided with a steam vent 131 that is connected to the outside. The steam flowing out of the steam outlet can be discharged from the steam vent 131.

[0113] For example, the steam outlet 130 is located at the bottom of the housing 110, and as described above, the steam vent 131 faces the surface to be cleaned. This allows steam to be ejected toward the surface to be cleaned. In a specific implementation, the steam outlet 130 may be located at the bottom of the bottom housing 111.

[0114] Additionally, refer to Figure 6 In this embodiment of the application, the steam outlet 130 may be located on the side of the roller brush assembly 150 away from the heating element 121.

[0115] In some embodiments, such as Figure 7As shown, the angle α between the axial direction of the exhaust port 131 and the bottom end face of the housing 110 can be 20°~60°. That is, the axial direction of the exhaust port 131 should be tilted at a certain angle away from the roller brush assembly 150, so that the steam outlet direction is as far away from the roller brush assembly 150 as possible. This can minimize the risk of the steam discharged from the exhaust port 130 being sucked into the dust collection assembly 160, which would damage the dust collection motor 162 in the dust collection assembly 160 and / or reduce the effectiveness of the steam discharged from the exhaust port 130 on the surface to be cleaned.

[0116] In practical implementation, one possible approach is to make the angle of the steam outlet 130 relative to the bottom end face of the housing 110 adjustable. This allows for flexible adjustment of the tilt angle of the exhaust port 131 relative to the bottom end face of the housing according to actual mite removal needs. For example, when the steam assembly 120 and the vacuuming assembly 160 are operating simultaneously, the angle of the steam outlet 130 can be adjusted so that its exhaust port 131 is tilted at a certain angle away from the roller brush assembly 150. As another example, when only the steam assembly 120 is operating, the angle of the steam outlet 130 can be adjusted so that its exhaust port 131 blows as vertically as possible onto the surface to be cleaned, improving steam utilization.

[0117] Additionally, refer to Figure 6 , Figure 7 The steam outlet 130 is provided with a protrusion 1362 at a position corresponding to the exhaust port 131. The exhaust port 131 can extend along the inside of the protrusion 1362, which increases the length of the exhaust port 131 along its own axial direction, making the steam discharge more concentrated. It is understood that the bottom shell 111 may include a protective cover 1363 for protecting the steam outlet 130. The protective cover 1363 may be provided with a clearance hole (not shown) at a position corresponding to the protrusion 1362, so that the protrusion 1362 can extend out of the bottom shell 111.

[0118] Figure 8 This is a cross-sectional view of the steam outlet component in a mite remover provided in one embodiment of this application. Figure 9 This is an exploded structural diagram of the steam outlet component in a mite remover provided in one embodiment of this application. Figure 10 This is a cross-sectional view of the steam outlet component in a mite remover provided in one embodiment of this application.

[0119] Reference Figure 8The steam outlet component 130 has a confining chamber 1301 and a steam outlet chamber 1302 that are connected to each other. The steam outlet component 130 has a steam inlet hole 132 that communicates with the confining chamber 1301. The steam inlet hole 132 is used to communicate with the steam assembly 120. In addition, the steam outlet chamber 1302 has a steam exhaust hole 131 that communicates with the outside, so that at least part of the steam from the steam assembly 120 passes through the confining chamber 1301 and the steam outlet chamber 1302 in sequence and is discharged from the steam exhaust hole 131.

[0120] In the above scheme, by constructing a retention chamber 1301 and a steam outlet chamber 1302 in the steam outlet component 130, at least part of the steam enters the retention chamber 1301 and comes into contact with the cavity wall of the retention chamber 1301. The liquid phase components and solid phase impurities carried in this part of the steam will adhere to the cavity wall of the retention chamber 1301 and roll off and accumulate at the bottom of the retention chamber 1301 under the action of gravity, without entering the steam outlet chamber 1302. The gas phase components in this part of the steam will continue to enter the steam outlet chamber 1302 and be discharged from the steam outlet component 130 through the steam exhaust hole 131 to perform mite removal operation on the surface to be cleaned. During this process, since a retention chamber 1301 is provided between the steam outlet chamber 1302 and the steam assembly 120, the liquid phase components and solid phase impurities in the steam can be at least partially removed, which reduces the liquid phase components and solid phase impurities in the steam discharged from the steam outlet 130, greatly reducing the probability that the steam will wet the surface to be cleaned during the mite removal process, and also avoiding the situation where solid phase impurities block the air outlet.

[0121] In a specific implementation, the stagnation chamber 1301 and the steam outlet chamber 1302 are arranged sequentially in a direction perpendicular to the Z direction, and the connection point between the stagnation chamber 1301 and the steam outlet chamber 1302 is located at the top of the stagnation chamber 1301 and the steam outlet chamber 1302; the steam inlet 132 is connected to the top of the stagnation chamber 1301.

[0122] As mentioned above, the Z direction is the direction from the bottom side to the top side of the mite remover 100, that is, from the bottom of the outer shell 110 to the top of the outer shell 110.

[0123] The arrangement of the retention chamber 1301 and the steam outlet chamber 1302 in a direction perpendicular to the Z-direction means that they are arranged at approximately the same height, not one higher than the other. The connection point between the retention chamber 1301 and the steam outlet chamber 1302 is located at their tops. The steam inlet 132 is connected to the top of the retention chamber 1301. Thus, the tops of the retention chamber 1301 and the steam outlet chamber 1302 are actually connected, while other parts are not. Gas flow between them occurs at the top; in other words, steam in the retention chamber 1301 is discharged to the steam outlet chamber 1302 through the top of the retention chamber 1301.

[0124] Thus, the gas flow path of the steam outlet 130 in this embodiment of the application can include two paths:

[0125] After steam enters the steam inlet 132, most of the steam enters the retention chamber 1301. The liquid components and solid impurities carried in this part of the steam will adhere to the cavity wall of the retention chamber 1301 and roll off and accumulate at the bottom of the retention chamber 1301 under the action of gravity, instead of entering the steam outlet chamber 1302. The gaseous components in this part of the steam will enter the steam outlet chamber 1302 through the top of the retention chamber 1301 and be discharged from the steam outlet 130 through the steam exhaust port 131.

[0126] Of the steam entering the steam inlet 132, a small portion enters the steam outlet chamber 1302 directly from the top of the steam outlet chamber 1302 and is discharged from the steam outlet 130 through the steam outlet 131.

[0127] For example, the steam outlet component 130 may include an internally hollow housing 133, the housing 133 including a first bottom wall 1331 facing the surface to be cleaned; a partition 1332 is provided inside the housing 133, the partition 1332 extending from the first bottom wall 1331 in a direction away from the first bottom wall 1331, to divide the housing 133 into a retention chamber 1301 and a steam outlet chamber 1302. This arrangement facilitates the processing of the steam outlet component 130, and also facilitates the liquid and solid components in the retention chamber 1301 to roll down along the wall of the partition 1332 and accumulate at the bottom of the retention chamber 1301.

[0128] In a further improvement to the above embodiment, the baffle 1332 can be extended along the direction from the top of the steam outlet 130 to the bottom of the steam outlet 130, that is, perpendicular to the first bottom wall 1331, so that the liquid and solid components attached to the baffle 1332 can roll off.

[0129] Continue to refer to Figure 8 In this embodiment, the housing 133 further includes a first top wall 1333 disposed opposite to the first bottom wall 1331. The steam inlet 132 may be located on the first top wall 1333, and the steam outlet 131 may be located on the first bottom wall 1331. This arrangement maximizes the distance between the steam inlet 132 and the steam outlet 131, thereby removing as much liquid and solid components as possible from the steam.

[0130] In this embodiment, the partition 1332 and the first top wall 1333 are spaced apart by a predetermined distance to allow the retention chamber 1301 and the steam outlet chamber 1302 to communicate. Even though the connection between the retention chamber 1301 and the steam outlet chamber 1302 is located near the top of the steam outlet component 130, steam enters the retention chamber 1301 from the first top wall 1333. The liquid and solid components in the steam can fully enter the retention chamber 1301 and deposit at its bottom. The gaseous component in the steam has a lower density and can change direction along the partition 1332, flowing through the top of the partition 1332 back into the steam outlet chamber, and then exiting the steam outlet component 130 through the exhaust port 131. Throughout this process, the steam has a relatively long flow path, effectively separating the gaseous component from the liquid and solid components.

[0131] Reference Figure 10 It is understandable that, given the gap between the top of the baffle 1332 and the first top wall 1333, to maximize the amount of steam entering the retention chamber 1301 from the steam inlet 132, at least a portion of the opening of the steam inlet 132 can be positioned directly opposite the retention chamber 1301. Alternatively, the entire opening of the steam inlet 132 can be positioned directly opposite the retention chamber 1301. It should be noted that "at least a portion of the opening of the steam inlet 132 being directly opposite the retention chamber 1301" specifically means that... Figure 8 When viewed from above, the steam inlet 132 and the stagnation chamber 1301 have overlapping areas.

[0132] In this embodiment of the application, in order to optimize the removal effect of liquid and solid components in steam by the retention chamber 1301, the retention chamber 1301 can have the same cross-sectional area at different positions in the normal direction of the first top wall 1333, and the steam outlet chamber 1302 can also have the same cross-sectional area at different positions in the normal direction of the first top wall 1333; the cross-sectional area of ​​the retention chamber 1301 is 1.5 times to 3.5 times the cross-sectional area of ​​the steam outlet chamber 1302.

[0133] Additionally, refer to Figure 9 In this embodiment of the application, the stagnation chamber 1301 is constructed in the shape of an elongated strip, and the steam inlet 132 is located between the two ends of the length direction of the stagnation chamber 1301. The width dimension of the stagnation chamber 1301 gradually narrows from the steam inlet 132 toward the two ends of the length direction of the stagnation chamber 1301.

[0134] For example, the ratio of the width of the steam outlet chamber 1302 at the location of the steam inlet 132 to the width of the stagnation chamber 1301 at the location of the steam inlet 132 is 2:4.

[0135] For example, in combination Figure 5There are multiple exhaust holes 131, which are arranged at intervals along the length of the retention chamber 1301 on the first bottom wall 1331.

[0136] After steam flows into the retention chamber 1301 through the steam inlet 132, as the steam gradually flows away from the steam inlet 132, its kinetic energy gradually weakens and its flow velocity slows down. When there are multiple steam outlets 131, it is very easy for the amount of steam discharged from each steam outlet 131 to be uneven. However, by gradually narrowing the width of the retention chamber 1301 from the steam inlet 132 towards both ends of the length of the retention chamber 1301, the cross-section of the steam flow channel narrows as it moves away from the steam inlet 132. This can, to a certain extent, prevent the flow velocity of the steam with decreasing kinetic energy from decreasing excessively, making the steam flow velocity at various positions along the length of the retention chamber 1301 approximately the same, reducing this velocity unevenness, and facilitating the discharge of an equal amount of steam from each steam outlet 131.

[0137] In this embodiment of the application, in order to facilitate the processing and manufacturing of the housing 133, it is advisable to form the housing 133 in separate parts, referring to... Figure 9 For example, the housing 133 includes a first part 135 and a second part 136 that overlap each other. The second part 136 has a hollow structure with an opening inside. A mounting groove 1361 surrounding the opening is provided on the end face of the opening of the second part 136. The first part 135 is provided with an insert 1351 corresponding to the mounting groove 1361. The insert 1351 extends into the mounting groove 1361 to seal the connection between the first part 135 and the second part 136. Here, the insert 1351 is provided correspondingly to the mounting groove 1361. When the mounting groove 1361 is an annular structure that surrounds the opening, the insert 1351 can also be formed as an annular structure.

[0138] Figure 11 This is a schematic diagram of another structure of the steam outlet component in a mite remover provided in one embodiment of this application.

[0139] In the embodiments of this application, reference is made to Figure 11 A connecting rib 1352 can be provided on the end face of the insert 1351 opposite to the first part 135. The connecting rib 1352 can be formed into a ring around the entire circumference of the insert 1351. After the insert 1351 is inserted into the mounting groove 1361, the steam outlet 130 is heated as a whole, and the connecting rib 1352 can be softened or melted to bond the insert 1351 to the inner wall of the mounting groove 1361, thereby achieving a firm connection between the insert 1351 and the mounting groove 1361.

[0140] Continue to refer to Figure 10The steam outlet component 130 also includes a transfer pipe 137. One port of the transfer pipe 137 is connected to the first top wall 1333 and communicates with the steam inlet 132. The other port of the transfer pipe 137 is used to communicate with the steam assembly 120. By providing the transfer pipe 137, the connection between the steam inlet 132 of the steam outlet component 130 and the exhaust port 131 of the steam assembly 120 can be facilitated through the pipeline.

[0141] In some other examples, the housing 133 is also provided with a first connecting part 138, which is connected to the housing 110 by fasteners.

[0142] Figure 12 This is a schematic diagram of a mite remover with a two-way solenoid valve provided in one embodiment of this application.

[0143] Reference Figure 12 In this embodiment, to facilitate the discharge of liquid accumulated in the retention chamber 1301, a liquid outlet 134 is provided on the retention chamber 1301, which is connected to the inlet of the drive pump 123. Thus, when the drive pump 123 is running, it can draw away the liquid from the retention chamber 1301. Since the drive pump 123 is also connected to the heating element 121, the liquid in the retention chamber 1301 can continue to be used to generate steam.

[0144] In this embodiment of the application, the steam assembly 120 may further include a two-way solenoid valve 125. The two-way solenoid valve 125 includes a first inlet 1251, a second inlet 1252 and an outlet 1253. The first inlet 1251 and the second inlet 1252 are respectively connected to the water tank 122 and the liquid outlet 134. The outlet 1253 of the two-way solenoid valve 125 is connected to the inlet of the drive pump 123.

[0145] The mite remover 100 may also include a controller 190, which is electrically connected to a two-way solenoid valve 125 and a drive pump 123. The controller 190 is used to control the second inlet 1252 to open for a second preset time interval every first preset time interval when the drive pump 123 is running. That is, the second inlet 1252 is normally closed and opens for the second preset time interval every first preset time interval. For example, the first preset time interval can be 20 seconds, and the second preset time interval can be 5 seconds. This way, the drive pump 123 draws liquid from the steam outlet 130 for 5 seconds every 20 seconds to prevent excessive liquid accumulation in the retention chamber 1301, and also recycles the water in the retention chamber 1301.

[0146] Understandably, after the mite remover 100 has been used for a period of time, some solid impurities may accumulate in the retention chamber. To prevent these solid components from being drawn into the drive pump 123 and affecting its service life, a filter barrier can be installed between the drive pump 123 and the liquid outlet 134. Specifically, the liquid outlet 134 and the second inlet 1252 are connected by a pipe (not shown), and a filter screen is installed in this pipe.

[0147]

Roller Brush Component

[0148] As mentioned above, the roller brush assembly 150 is used to roll into contact with the surface to be cleaned, thereby patting and vibrating the surface to be cleaned, causing mites killed on the surface or inside the textile to be cleaned, as well as dust, to be lifted up.

[0149] Combined with reference Figure 2 , Figure 3 The outer casing 110 includes a roller brush housing 152. The aforementioned first receiving cavity 1521 is located within the roller brush housing 152. The roller brush housing 152 may include a bottom cover 1523 and a top cover 1522 with a bottom opening. Two side walls 113 are also provided at both ends along the Y direction on the bottom casing 111. The two side walls 113, the bottom cover 1523, and the top cover 1522 together enclose the aforementioned first receiving cavity 1521. The roller brush 151 is rotatably supported within the first receiving cavity 1521. Of course, it is necessary for at least a portion of the roller brush 151 to extend out of the first receiving cavity 1521 so as to be able to roll into contact with the surface to be cleaned. Here, one or more notches (not shown) can be provided on the bottom cover 1523 to allow the roller brush 151 to partially extend out of the roller brush housing 152.

[0150] Additionally, as mentioned above, the vacuuming assembly 160 has a vacuum port communicating with the first receiving cavity 1521, which is used to suck in dust mites stirred up by the roller brush 151 rolling into contact with the surface to be cleaned.

[0151] In some other examples, the roller brush assembly 150 also includes a roller brush motor 154 for driving the roller brush 151 to rotate. The roller brush motor 154 may be arranged on the side of the roller brush housing 152 facing the heating element 121.

[0152] In addition, the aforementioned steam outlet 130 can be disposed on the side of the roller brush assembly 150 away from the heating element 121.

[0153]

Vacuum Cleaning Component

[0154] Continue to refer to Figure 2 , Figure 3In this embodiment of the application, the dust collection assembly 160 includes a dust cup 161 and a dust collection motor 162; the air inlet 1611 of the dust cup forms the dust collection port of the dust collection assembly 160; the air outlet 1612 of the dust cup is connected to the air inlet 1626 of the dust collection motor; the dust cup 161 is disposed on the top of the outer shell 110, and the dust collection motor 162 is disposed in the receiving cavity 1101 and located between the water tank 122 and the heating element 121.

[0155] The dust cup 161 is connected to the vacuum motor 162. The vacuum motor 162 is used to generate negative pressure in the dust cup 161 to adsorb dust mites. After the dust mites are carried up by the vibration and tapping of the surface to be cleaned by the roller brush assembly 150, the dust mites are adsorbed into the dust cup 161 and filtered and removed through the dust cup 161. The clean air then enters the vacuum motor 162.

[0156] Here, in order to connect the suction port of the suction assembly 160, i.e. the air inlet 1611 of the dust cup, with the first accommodating cavity 1521, a suction pipe 1613 can be provided on the air inlet 1611 of the dust cup. One end of the suction pipe 1613 is connected to the air inlet 1611 of the dust cup, and the other end is located near the first accommodating cavity 1521 and connected to the first accommodating cavity 1521.

[0157] Understandably, the vacuum motor 162 is also provided with a first air outlet 1627 to allow the air that has passed through the dust cup 161 and entered the vacuum motor 162 to be discharged. In addition, the vacuum motor 162 is also provided with a second air outlet 1628, which is used to communicate with the drying assembly 180 and serve as the airflow source for the drying assembly 180.

[0158] In this embodiment, reference continues to be made to... Figure 6 The top of the outer casing 110 is provided with a handle 140, which can be held by hand during the use of the mite remover 100. The vacuum motor 162 is arranged below the handle 140 along a second direction, wherein the second direction is from the top of the outer casing 110 to the bottom of the outer casing 110 (parallel to the Z direction), that is... Figure 6 The diagram shows the vertical direction. In this way, when the operator holds the handle 140, the heavier vacuum motor 162 is located below the handle 140, resulting in a smaller torque relative to the operator's point of force application on the handle 140, making the operator's grip easier and more stable. It can be understood that "below the handle 140" can be directly below the handle 140, or slightly offset in the X or Y direction.

[0159] For example, the grip handle 140 and the dust cup 161 can be arranged sequentially in the first direction X.

[0160] Figure 13This is a schematic diagram of the structure of the dust collection component and the drying component in a mite removal device provided in an embodiment of this application.

[0161] Reference Figure 13 In some embodiments, the vacuum motor 162 may include a motor body 1621 and a motor housing 1622 covering the outside of the motor body 1621; the motor housing 1622 includes a first housing 1623 and a second housing 1624 connected to each other, the first housing 1623 and the second housing 1624 being arranged radially spaced apart from each other to define a silencing cavity 1625 for noise reduction. This can reduce the noise of the entire mite remover 100 and improve the user experience.

[0162] Drying Components

[0163] As mentioned earlier, the drying unit 180 is used to generate hot air, which can dehumidify and dry the textiles on the one hand, and kill mites, bacteria and other pests in the textiles on the other hand.

[0164] Combination Figure 3 , Figure 13 The drying assembly 180 includes a hot air outlet assembly 182 with a second accommodating cavity 1822 inside, and a heating unit 181 with a first heating cavity 1811 inside; wherein, the second accommodating cavity 1822 is provided with an air outlet 1821 communicating with the outside.

[0165] The first heating chamber 1811 is connected to the air outlet of the vacuum motor 162, such as the second air outlet 1628, to heat the airflow flowing from the vacuum motor 162. The first heating chamber 1811 is also connected to the second accommodating chamber 1822 so that the heated airflow is discharged from the air outlet 1821. Here, the heating unit 181 can be an electric heater that is powered on. The hot air outlet assembly 182 can be arranged between the roller brush assembly 150 and the heating element 121. It is understood that, since the first air outlet 1627 is provided on the vacuum motor 162, some of the air entering the vacuum motor 162 through the air inlet 1626 is discharged from the vacuum motor 162 through the first air outlet 1627, and some enters the drying assembly 180 from the second air outlet 1628 to be heated. This can prevent the vacuum motor 162 from overheating or malfunctioning.

[0166] In this embodiment, the heating element 121 can be arranged on the bottom side of the heating unit 181 to make the internal space of the mite remover 100 more efficient and the structure more compact.

[0167] It is understandable that the second air outlet 1628 of the vacuum motor 162 and the inlet of the first heating chamber 1811, the outlet of the first heating chamber 1811 and the inlet of the second accommodating chamber 1822 can be sealed together by pipes or the like.

[0168] Continue to refer to Figure 13 The hot air outlet assembly 182 may include a hot air housing 183, a second accommodating cavity 1822 formed inside the hot air housing 183, and an air outlet 1821 disposed on the bottom of the hot air housing 183. There may be multiple air outlets 1821, which are arranged side by side along the Y direction at the bottom of the hot air housing 183 to spray hot air toward the surface to be cleaned.

[0169] Figure 14 This is a schematic diagram illustrating another structure of the mite remover provided in one embodiment of this application. Figure 15 This is a schematic diagram of another structure of the mite remover provided in one embodiment of this application.

[0170] In the embodiments of this application, reference is made to Figure 14 In the heating element 121, a second heating cavity 1213 is defined between the outer surface of the heating element body 1214 and the heating element shell 1215. The second heating cavity 1213 communicates with the first heating cavity 1811 and the second accommodating cavity 1822, so that the first heating cavity 1811 and the second accommodating cavity 1822 are connected through the second heating cavity 1213. In this way, the air discharged from the second air outlet 1628 of the vacuum cleaner motor 162 can be heated by the heating unit 181 through the first heating cavity 1811, and then heated by the heating element 121 through the second heating cavity 1213. Under the same hot air outlet temperature, the power consumption of the heating unit 181 can be reduced.

[0171] In a specific implementation, the outlet of the first heating chamber 1811 and the inlet of the second heating chamber 1213 can be connected through the first pipe 184, and the outlet of the second heating chamber 1213 and the inlet of the second accommodating chamber 1822 can be connected through the second pipe 185, thereby connecting the first heating chamber 1811, the second heating chamber 1213 and the second accommodating chamber 1822 in series.

[0172] Reference Figure 15 As another possible implementation, the second heating chamber 1213 is connected to the air outlet of the vacuum motor 162, such as the second air outlet 1628, to heat the airflow flowing from the vacuum motor 162; the second heating chamber 1213 is also connected to the second accommodating cavity 1822 so that the heated airflow is discharged from the air outlet 1821. That is, the drying assembly 180 may not be provided, and the air discharged from the vacuum motor 162 may be heated simply by the second heating chamber 1213 formed in the heating element 121.

[0173] In a specific implementation, the second air outlet 1628 of the vacuum motor 162 and the inlet of the second heating chamber 1213 can be connected through the third pipe 186, and the outlet of the second heating chamber 1213 and the inlet of the second accommodating chamber 1822 can be connected through the fourth pipe 187.

[0174] [Buzzer and UV sterilization unit]

[0175] Figure 16 This is a schematic diagram from another angle of a mite removal device provided in one embodiment of this application.

[0176] Combination Figure 2 , Figure 3 , Figure 16 The buzzer 141 can be located inside the receiving cavity 1101 inside the housing 110 and fixed to the bottom of the housing 110. The buzzer 141 is located between the hot air outlet assembly 182 and the roller brush assembly 150. In addition, in order to enable the ultrasonic waves emitted by the buzzer 141 to better penetrate the housing 110, several through holes 1411 are provided on the housing 110 corresponding to the positions of the buzzer 141.

[0177] It is understood that the buzzer 141 in this application embodiment can generate ultrasonic waves up to 4000Hz, which are harmless to humans and pets, but can act on mites to disrupt their physiological system, cause loss of appetite, reduce food intake and reproduction, slow down movement speed, and kill mites.

[0178] In practical use, the ultrasonic waves emitted by the buzzer 141 can be transmitted to the outside through the through-hole 1411 on the housing, thereby achieving a more effective mite removal effect. The buzzer 141 can be an electromagnetic buzzer, etc.

[0179] The ultraviolet sterilization unit 142 can be located at the bottom of the housing 110, and the bottom of the housing 110 is provided with an opening 1421 to allow the ultraviolet light emitted by the ultraviolet sterilization unit 142 to pass through. A transparent cover plate can be provided at the opening 1421.

[0180] Secondly, this application also provides a control method for a mite remover. This control method is used to control the mite remover 100 of the aforementioned embodiment. The structure, function, and working principle of the mite remover 100 have been described in detail and will not be repeated here. As mentioned earlier, the steam outlet 130 is used to discharge the steam generated by the steam assembly 120 to the surface to be cleaned; the suction port of the vacuum assembly 160 and the exhaust port 131 of the steam outlet 130 are arranged sequentially in the X-direction of travel of the mite remover 100. Therefore, it is possible that the steam discharged from the exhaust port 131 may be sucked into the vacuum assembly 160. This not only prevents the mite removal effect of the steam assembly 120 from reaching its maximum, but may also cause the vacuum assembly 160 to malfunction, reducing the reliability and mite removal effect of the mite remover.

[0181] Figure 17 This is a schematic flowchart illustrating the control method of a mite remover provided in an embodiment of this application.

[0182] Reference Figure 17 Based on the above problems, the control method for the mite remover provided in this application includes:

[0183] S10. Upon receiving an instruction to operate the steam assembly, control the steam assembly to operate and determine whether the vacuuming assembly is in working condition.

[0184] S20. If it is determined that the vacuuming component is in working condition, control the target motor to operate at the target preset power; wherein, the target preset power is less than the working power of the target motor when the steam component stops operating and the vacuuming component is in working condition; or, the target preset power is less than or equal to the minimum working power of the target motor when the steam component stops operating and the vacuuming component is in working condition.

[0185] In the above solution, on the one hand, by setting up a steam component, a steam outlet component, and a dust collection component, the steam generated by the steam component is used to sterilize and remove mites from the surface to be cleaned through the steam outlet component, and then the dust collection component is used to adsorb the killed mites. In particular, the high-temperature steam can enter the interior of the textile through the small gaps and holes between the textiles to achieve deep sterilization and mite removal, and the dust collection component is also used to adsorb dust and killed mites, so that the mite removal device has a good mite removal effect.

[0186] On the other hand, operating the steam and vacuum components simultaneously reduces operator time compared to operating them independently. When both components are running concurrently, the target motor operates at a lower preset power, which reduces the amount of steam drawn into the vacuum component, preventing it from malfunctioning due to steam interference and increasing the overall reliability of the mite remover.

[0187] The system receives a command to activate the steam unit, such as when an operator presses the steam function button on the mite remover. Similarly, it receives a command to deactivate the steam unit, such as when an operator releases the steam function button on the mite remover.

[0188] Additionally, it should be noted that in the embodiments of this application, the target motor may be equipped with two, three, or other numbers of gears as needed. These different gears correspond to different working power. The minimum working power of the target motor mentioned above corresponds to the working power of the lowest gear among the different gears, i.e., the minimum working power.

[0189] Of course, when the target motor works alone, it may only have one working level, that is, only one working power. In this case, when the steam component stops running and the dust collection component is in working condition, the working power of the target motor is the power corresponding to the only working level.

[0190] In addition, the control method described above is applicable to the control process when the exhaust port 131 of the steam outlet 130 is arranged adjacent to the dust suction port of the dust collection component 160. Of course, when the exhaust port 131 is located in front of the dust suction port, the amount of steam intake can be significantly reduced, and the effect of improving the reliability of the mite remover 100 is most obvious.

[0191] In this embodiment, if it is determined that the vacuuming component is not in operation, the steam component continues to run, and the vacuum motor remains off. In other words, when the vacuum cleaner is not in operation, there is no possibility that the steam component and the vacuuming component will operate simultaneously. At this time, the steam component continues to run, and the vacuum motor remains off.

[0192] In this embodiment of the application, as described above, the mite removal device 100 further includes a roller brush assembly 150, which includes a roller brush motor 154. The vacuuming assembly 160 includes a vacuuming motor 162, and is used to vacuum up dust mites carried up by the roller brush assembly 150 on the surface to be cleaned during operation.

[0193] Furthermore, the target motor can be at least one of a vacuum cleaner motor and a roller brush motor. The target preset power corresponding to the target motor includes at least one of a first preset power corresponding to the vacuum cleaner motor and a second preset power corresponding to the roller brush motor.

[0194] Furthermore, controlling the target motor to operate at the target preset power may include:

[0195] Control the vacuum cleaner motor to operate at a first preset power, and control the roller brush motor to operate at a second preset power.

[0196] Alternatively, control the vacuum motor to operate at the first preset power.

[0197] Alternatively, control the roller brush motor to operate at a second preset power.

[0198] In this embodiment of the application, after controlling the target motor to operate at the target preset power in step S20, the control method further includes:

[0199] Upon receiving a command to stop the steam unit, the system controls the steam unit to stop operating and determines whether the vacuuming unit is in operation.

[0200] If the dust collection component is determined to be in operation, the target motor is controlled to operate at the power selected by the user.

[0201] Therefore, if the vacuuming component is still working after the steam component stops operating, it means that the user still needs to perform vacuuming work. At this time, there is no possibility that the steam component and the vacuuming component will work at the same time, and the power of the target motor can be restored to the working power currently selected by the user.

[0202] It should be noted that the operating power selected by the user can be changed by the user during the use of the mite remover as needed, or it can be the target motor operating power when the mite remover is started.

[0203] In this embodiment of the application, the movement state of the mite remover includes a forward state and a backward state. The movement state of the mite remover from the exhaust port toward the suction port is defined as the backward state, and the movement state of the mite remover from the suction port toward the exhaust port is defined as the forward state.

[0204] If it is determined that the vacuuming component is in working condition, then controlling the target motor to operate at the target preset power includes: if it is determined that the vacuuming component is in working condition, then controlling the target motor to operate at the target preset power according to the movement state of the mite remover.

[0205] If the mite remover is in reverse mode, the surface of the fabric to be cleaned may be rolled up by the roller brush, potentially damaging the fibers. In this case, the operating power of the roller brush motor should be reduced to minimize the risk. However, in reverse mode, with the suction port of the vacuum component in front of the exhaust port of the steam outlet, the likelihood of steam from the exhaust port entering the suction port is low, and the operating power of the vacuum motor does not need to be reduced.

[0206] In practice, the control methods for mite removal devices also include:

[0207] If it is determined that the vacuuming component is in working condition and the mite remover is in reverse position, the vacuuming motor is controlled to operate at the working power selected by the user.

[0208] If the vacuuming component is determined to be in operation, the target motor is controlled to operate at the target preset power based on the mite remover's movement, including:

[0209] If it is determined that the vacuuming component is in working condition and the mite remover is in reverse movement, then the roller brush motor is controlled to operate at the third preset power. Here, the third preset power can be less than or equal to the second preset power.

[0210] In this embodiment of the application, if it is determined that the dust collection component is in working state and the mite remover is in forward state, the roller brush motor is controlled to run at the initial working power.

[0211] If the vacuuming component is determined to be in operation, the target motor is controlled to operate at the target preset power based on the mite remover's movement, including:

[0212] If it is determined that the vacuuming component is in working condition and the mite remover is in forward motion, then the vacuuming motor is controlled to operate at the first preset power.

[0213] Thus, when the mite remover is in forward motion, by operating the vacuum motor at the first preset power and controlling the roller brush motor to operate at the initial working power, the amount of steam drawn into the vacuum motor is reduced, thereby improving the reliability of the mite remover.

[0214] In this embodiment of the application, as described above, the mite remover also has a drying function. Exemplarily, the control method for the mite remover further includes:

[0215] Obtain the humidity value of the surface to be cleaned;

[0216] If the humidity value is less than the first humidity threshold, the heating unit in the drying assembly is controlled to operate at the first heating power.

[0217] If the humidity value is greater than the second humidity threshold, the heating unit in the drying assembly is controlled to operate at the second heating power, wherein the first heating power is less than the second heating power, and the first humidity threshold is less than the second humidity threshold.

[0218] In this way, when the humidity of the surface to be cleaned is less than a first humidity threshold (i.e., the humidity is low), the heating unit is controlled to operate at a lower first heating power. When the humidity of the surface to be cleaned is greater than a second humidity threshold (i.e., the humidity is high), the heating unit is controlled to operate at a higher second heating power. By controlling the operating power of the heating unit according to the specific humidity of the surface to be cleaned, as described above, the power consumption of the heating unit can be reduced.

[0219] In addition, as mentioned above, the heating element also includes a second heating chamber to provide auxiliary heating to the heating unit. The second heating chamber and the first heating chamber in the heating unit can be connected in series or in parallel. In this case, the control method for the mite remover can also include:

[0220] Obtain the humidity value of the surface to be cleaned and the temperature value of the heating element;

[0221] The operating power of the heating unit in the drying assembly is controlled based on humidity and temperature values.

[0222] In practice, the operating power of the heating unit in the drying assembly is controlled based on humidity and temperature values, specifically including:

[0223] When the humidity value is less than the first humidity threshold, if the temperature value is less than or equal to a preset temperature threshold, the heating unit is controlled to operate at the first heating power; if the temperature value is greater than the preset temperature threshold, the heating unit is controlled to operate at the third heating power.

[0224] When the humidity value is greater than the second humidity threshold, if the temperature value is less than or equal to the preset temperature threshold, the heating unit is controlled to operate at the second heating power; if the temperature value is greater than the preset temperature threshold, the heating unit is controlled to operate at the fourth heating power.

[0225] Wherein, the third heating power is less than the first heating power, and the fourth heating power is less than the second heating power.

[0226] Thus, when the humidity of the surface to be cleaned is less than the first humidity threshold (i.e., the humidity is low), if the temperature value is less than or equal to the preset temperature threshold, it indicates that the heating element's heating temperature is insufficient, and the heating unit can be controlled to operate at the first heating power. If the temperature value is greater than the preset temperature threshold, it indicates that the heating element has a sufficient heating temperature, and the heating unit can be controlled to operate at a third heating power lower than the first heating power.

[0227] When the humidity of the surface to be cleaned exceeds the second humidity threshold (i.e., the humidity is high), if the temperature is less than or equal to the preset temperature threshold, it indicates that the heating element's heating temperature is insufficient. In this case, the heating unit can be controlled to operate at a second heating power, which is greater than the first heating power. If the temperature exceeds the preset temperature threshold, it indicates that the heating element's heating temperature is sufficient. In this case, the heating unit can be controlled to operate at a fourth heating power, which is less than the second heating power. That is, since the second heating chamber in the heating element also plays an auxiliary heating role, the operating power of the heating unit can be reduced, thus reducing its power consumption.

[0228] In addition, the control method of the mite remover in this embodiment further includes: upon receiving an instruction to operate the vacuuming component, determining whether the steam component is in operation; if so, controlling the target motor to operate at a target preset power. Thus, when receiving the operating instruction to operate the vacuuming component, if the steam component is already in operation, the power of the vacuuming motor needs to be adjusted to minimize the amount of steam generated by the steam outlet during simultaneous operation of the vacuuming component and the steam component being drawn into the vacuuming component, or to prevent steam from being drawn into the vacuuming component altogether.

[0229] It is understandable that the steps to control the operation of the steam component can be performed simultaneously with the determination of the working status of the vacuum component, or they can be performed after the working efficiency of the vacuum motor in the vacuum component decreases.

[0230] Thirdly, this application also provides a mite remover 100. It should be noted that the mite remover 100 here is an improvement on the mite remover 100 of the aforementioned embodiments. The specific structure, function, and working principle of the mite remover 100 have been described in detail above and will not be repeated here.

[0231] Figure 18 This is a structural block diagram of a mite removal device 100 provided in an embodiment of this application.

[0232] Reference Figure 18 As described above, the mite remover 100 of this application embodiment includes: a steam assembly 120; a steam outlet 130 having a steam vent 131, and the steam outlet 130 is configured to discharge the steam generated by the steam assembly 120 to the surface to be cleaned through the steam vent 131; a vacuum assembly 160 having a vacuum port, the vacuum port and the steam vent 131 of the steam outlet 130 being arranged sequentially in the traveling direction of the mite remover 100; and a controller 190 electrically connected to the steam assembly 120 and the vacuum assembly 160; the controller 190 is used to: control the steam assembly 120 to operate when receiving an instruction to operate the steam assembly 120, and determine whether the vacuum assembly 160 is in a working state; if it is determined that the vacuum assembly 160 is in a working state, control the target motor to operate at a target preset power;

[0233] Specifically, the target preset power is less than the operating power of the target motor when the steam component 120 stops operating and the dust collection component 160 is in operation; or, the target preset power is less than or equal to the minimum operating power of the target motor when the steam component 120 stops operating and the dust collection component 160 is in operation.

[0234] In the above solution, on the one hand, by setting up a steam component 120, a steam outlet 130, and a dust collection component 160, the steam generated by the steam component 120 is used to sterilize and remove mites from the surface to be cleaned through the steam outlet 130, and then the dust collection component 160 is used to adsorb the killed mites. The high-temperature steam can enter the interior of the textile through the small gaps and holes between the textiles to perform deep sterilization and mite removal, and the dust collection component 160 is used to adsorb dust and killed mites, so that the mite removal device 100 has a better mite removal effect.

[0235] On the other hand, when the steam component 120 and the vacuum component 160 are running simultaneously, the amount of steam drawn into the vacuum component 160 can be reduced to a certain extent because the target motor is controlled to run at a smaller target preset power, thus preventing the vacuum component 160 from malfunctioning due to the steam. This also increases the working reliability of the mite remover 100.

[0236] In this embodiment of the application, the target motor includes at least the vacuum motor 162 of the vacuum assembly 160, and the steam assembly 120 includes a heating element 121, a water tank 122 and a drive pump 123. The heating element 121 has a heating chamber (not shown) inside. The outlet of the drive pump 123 is connected to the inlet 1211 of the heating element, and the inlet of the drive pump 123 is connected to the outlet of the water tank 122. The heating element 121 is used to convert the water pumped by the drive pump 123 into steam.

[0237] The controller 190 is also used to control the heating element 121 and the drive pump 123 to continue operating and maintain the vacuum motor 162 in the off state when it is determined that the vacuum assembly 160 is in an inactive state.

[0238] In this embodiment of the application, the mite removal device 100 also includes a roller brush assembly 150, a dust collection assembly 160 including a dust collection motor 162, and a roller brush assembly 150 including a roller brush motor 154. The dust collection assembly 160 is used to suck away the dust mites brought up on the surface to be cleaned when the roller brush assembly 150 is running.

[0239] The target motor includes at least one of a vacuum motor 162 and a roller brush motor 154;

[0240] The target preset power corresponds to at least one of the following for the target motor: a first preset power corresponding to the vacuum motor 162 and a second preset power corresponding to the roller brush motor 154.

[0241] Furthermore, after controlling the target motor to operate at the target preset power, the controller 190 is also used to:

[0242] Upon receiving a command to stop the steam assembly 120, the system controls the steam assembly 120 to stop operating and determines whether the vacuum assembly 160 is in operation.

[0243] If it is determined that the vacuuming component 160 is in working condition, the target motor is controlled to operate at the working power selected by the user.

[0244] Furthermore, as mentioned above, the movement state of the mite remover 100 from the exhaust port 131 toward the suction port is defined as the backward state, and the movement state of the mite remover 100 from the suction port toward the exhaust port 131 is defined as the forward state.

[0245] The mite remover 100 also includes an accelerometer 143 electrically connected to the controller 190, the accelerometer 143 being used to detect the acceleration signal of the mite remover 100; the mite remover 100 also includes a roller brush assembly 150, and a vacuuming assembly 160 being used to vacuum away the dust mites carried up by the roller brush assembly 150 on the surface to be cleaned during operation.

[0246] The controller 190 is also used to determine the travel status of the mite remover 100 based on the acceleration signal detected by the acceleration sensor 143 if it is determined that the dust collection component 160 is in working state. The travel status includes forward state or backward state. Specifically, the controller is used to control the target motor to operate at the target preset power according to the travel status of the mite remover 100.

[0247] In this embodiment of the application, the vacuuming component 160 includes a vacuuming motor 162; the controller 190 is also used to control the vacuuming motor 162 to operate at the working power selected by the user if it is determined that the vacuuming component 160 is in the working state and the mite remover 100 is in the backward state.

[0248] The controller is specifically used to: if it is determined that the vacuuming component 160 is in working condition and the mite remover 100 is in a backward movement state, then control the roller brush motor 154 to operate at a third preset power.

[0249] Furthermore, the controller is also used to control the roller brush motor 154 to operate at the initial operating power if it is determined that the vacuuming component 160 is in working state and the mite remover 100 is in forward state.

[0250] The controller is specifically used to: if it is determined that the vacuuming component 160 is in working state and the mite remover 100 is in forward movement state, then control the vacuuming motor 162 to run at a first preset power.

[0251] In this embodiment of the application, the mite remover 100 also includes a drying component 180, which includes a heating unit 181; a humidity sensor 144 is provided at the bottom of the mite remover 100, which is used to detect the humidity value of the surface to be cleaned.

[0252] The controller 190 is also specifically used to acquire the humidity value detected by the humidity sensor 144; if the humidity value is less than the first humidity threshold, the controller controls the heating unit 181 to operate at the first heating power.

[0253] The controller 190 is further configured to control the heating unit 181 to operate at a second heating power if the humidity value is greater than a second humidity threshold, wherein the first heating power is less than the second heating power and the first humidity threshold is less than the second humidity threshold.

[0254] In this embodiment, the steam assembly 120 further includes a heating element 121 for generating steam. The heating element 121 is also used to reheat the airflow heated by the drying assembly 180. A temperature sensor 145 is provided on the heating element 121 for detecting the temperature of the heating element 121. The controller 190 is further specifically used for:

[0255] Obtain the humidity value of the surface to be cleaned and the temperature value of the heating element 121;

[0256] The operating power of the heating unit 181 is controlled according to the humidity and temperature values.

[0257] In specific implementation, controller 190 is also used for:

[0258] When the humidity value is less than the first humidity threshold, if the temperature value is less than or equal to a preset temperature threshold, the heating unit is controlled to operate at the first heating power; if the temperature value is greater than the preset temperature threshold, the heating unit is controlled to operate at the third heating power.

[0259] When the humidity value is greater than the second humidity threshold, if the temperature value is less than or equal to the preset temperature threshold, the heating unit is controlled to operate at the second heating power; if the temperature value is greater than the preset temperature threshold, the heating unit is controlled to operate at the fourth heating power.

[0260] Among them, the third heating power is less than the first heating power, and the fourth heating power is less than the second heating power.

[0261] It is understandable that the controller 190 may also control the operating power of the heating unit 181 solely based on the temperature of the outer surface of the heating element body 1214, i.e., the temperature of the heating element 121.

[0262] In this embodiment, the controller 190 is specifically used to control the operation of the heating element 121 and the drive pump 123 when it receives a working instruction to operate the steam assembly 120.

[0263] In this embodiment of the application, as described above, the mite remover 100 may further include an alarm unit and a detection sensor 124. The detection sensor 124 is used to detect the amount of water in the water tank 122. The controller 190 is electrically connected to the detection sensor 124 and the alarm unit, and is used to control the alarm unit to sound an alarm when the amount of water in the water tank 122 is less than a preset threshold.

[0264] Fourthly, this application also provides a computer-readable storage medium storing at least one instruction, which is loaded and executed by a processor to implement the control method of the mite remover as described in the foregoing embodiments. The implementation principle and technical effect are similar, and will not be repeated here.

[0265] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0266] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
