In addition, those skilled in the art can combine and combine the different embodiments or examples described in the present application and the features of the different embodiments or examples without contradiction.

[0058] With reference to FIGS. 1-3, the base of the dust collector according to the first aspect of the present application includes a base body 1 and a protective cover 2; the base body 1 is provided with a shearing assembly 10, and the shearing assembly 10 is provided with a movable blade part 121, and the shearing assembly 10 is adapted to shear hair attached to a brush head 31 of a dust collector body 3; the protective cover 2 is arranged on the movable blade part 121, and the protective cover 2 is provided with a plurality of through holes 21.

[0059] According to the base of the dust collector of the present application, during the dust collection process, the longer hair (the shorter hair cannot be wound and is directly sucked into the dust suction port 321 of the dust collector) wound on the brush head 31 passes through the through hole 21 of the protective cover 2 and contacts the shearing assembly 10, and is sheared.

[0060] It should be noted that in the related art, the shearing assembly 10 of the dust collector arranged on the base body 1 is usually exposed to the user, and in the use process, the user touches the stationary movable blade part 121 of the shearing assembly 10, which has the risk of cutting the user. Based on this problem, the related art also proposes a technical solution of arranging an extension piece below the shearing assembly 10 to push the movable blade part 121 out of the shell 32 of the base body 1 when the shearing assembly 10 works. However, in the case of accidental start of the base body 1, the movable blade part 121 of the shearing assembly 10 is pushed out, and there is still the risk of cutting the user, and the use safety is low.

[0061] According to the base of the dust collector of the present application, the protective cover 2 is arranged on the movable blade part 121 of the shearing assembly 10, and has a good protection effect through physical isolation, whether the shearing assembly 10 is stationary or accidentally started, which effectively improves the use safety of the dust collector. Moreover, the present application arranges the shearing assembly 10 on the base body 1, so that the user does not need to clean the hair on the brush head 31 by himself / herself, and also avoids the problem that arranging the shearing assembly 10 on the brush head 31 causes the dust collector body 3 to be too large in size and not conducive to being held by the user. In addition, the present application avoids the problem that when the user holds the dust collector body 3 to clean, the shearing assembly 10 and the fan (communicating with the dust suction port 321 for dust collection) of the dust collector work at the same time to generate a large amount of noise, which affects the user experience.

[0062] According to one embodiment of the present application, as shown in FIGS. 2, 4 and 5, the shearing assembly 10 includes a first comb-shaped blade 11 and a second comb-shaped blade 12, and the blade teeth of the first comb-shaped blade 11 and the blade teeth of the second comb-shaped blade 12 are opposite and movable relative to each other.

[0063] In the embodiment, the hair on the brush head 31 is sheared by the teeth of the first comb blade and the teeth of the second comb blade 12 in the axial direction of the brush head 31, that is, each set of teeth (one tooth of the first comb blade 11 and the corresponding tooth of the second comb blade 12) only shears the hair in a partial area, thereby avoiding hair accumulation and entanglement and affecting the shearing effect of the shearing assembly 10.

[0064] In the embodiment, the relative movement of the first comb blade 11 and the second comb blade 12 can be understood as one of the first comb blade 11 and the second comb blade 12 being fixed and the other being moved. Of course, the first comb blade 11 and the second comb blade 12 can also be moved simultaneously. The simultaneous movement can be reverse movement. Of course, the possibility of forward movement cannot be excluded. At this time, the first comb blade 11 and the second comb blade 12 have a certain speed difference to achieve the shearing effect. In addition, the direction of the relative movement can be parallel to the axial direction of the brush head 31 or at a certain angle, such as 90 degrees, to the axial direction of the brush head 31.

[0065] In the embodiment, the teeth of the first comb blade 11 and the teeth of the second comb blade 12 are arranged one by one. Of course, one tooth of the first comb blade 11 can correspond to two teeth of the second comb blade 12. The corresponding relationship and the corresponding number can be adjusted adaptively.

[0066] In the embodiment, the through hole 21 is arranged corresponding to at least part of the teeth of the first comb blade 11 and the teeth of the second comb blade 12. As described above, the through hole 21 also has the function of partitioning the hair on the brush head 31, thereby also achieving the effect of avoiding hair accumulation and entanglement.

[0067] In the embodiment, as shown in FIGS. 3 and 6, in the cross section perpendicular to the axial direction of the brush head 31, the surface of the protective cover 2 towards the brush head 31 is concave at both ends and convex in the middle. The convex structure avoids the first comb blade 11 or the second comb blade 12, and the concave structure does not hinder the rotation of the brush head 31 too much, thereby effectively improving the hair shearing efficiency.

[0068] According to an embodiment of the present application, as shown in FIGS. 6 and 7, the first comb blade 11 is fixed relative to the protective cover 2, and the second comb blade 12 is movable relative to the first comb blade 11. The second comb blade 12 forms a movable blade part 121. When the dust collector body 3 is placed on the base of the dust collector, the relative positions of the protective cover 2 and the first comb blade 11 of the dust collector body 3 are fixed. In the process of rotating the brush head 31, the first comb blade 11 constitutes a comb to comb the hair on the brush head 31, thereby avoiding hair accumulation and knotting and affecting the shearing effect.

[0069] In one embodiment, the top of the second comb blade 12 is lower than the top of the first comb blade 11 in the direction of the shearing assembly 10 pointing to the brush head 31, so that the hair on the brush head 31 is preferentially combed through the first comb blade 11 and then sheared between the first comb blade 11 and the second comb blade 12, improving the shearing effect. And due to the rotation of the brush head 31, the hair on the brush head 31 can be effectively stretched and contacted with the second comb blade 12 under the action of centrifugal force, and the hair remaining on the brush head 31 after shearing cannot be wound due to its short length, and then separated from the brush head 31.

[0070] In one embodiment, the first comb blade 11 at least partially abuts the brush head 31 in the direction of the shearing assembly 10 pointing to the brush head 31. The first comb blade 11 abuttingly arranged ensures the combing effect on the hair on the brush head 31, and through abutting, the blade teeth correspond to specific partitions on the brush head 31, avoiding the ends of hairs in different partitions away from the brush head 31 from winding with each other and affecting the shearing effect.

[0071] In this embodiment, the first comb blade 11 and the second comb blade 12 are arranged below the top of the protective cover 2. Of course, in the case that the first comb blade 11 is fixed relative to the protective cover 2, the first comb blade 11 can also be arranged protruding from the top of the protective cover 2; and the top of the protective cover 2 can also abut the brush head 31, further defining the partitions on the brush head 31.

[0072] According to one embodiment of the present application, as shown in FIGS. 6 and 7, the minimum distance between the second comb blade 12 and the outer surface of the brush head 31 is less than or equal to 2 mm. This effectively ensures the shearing effect, reduces the length of the hair remaining on the brush head 31, and improves the cleaning effect of the brush head 31.

[0073] Of course, the distance between the second comb blade 12 and the outer surface of the brush head 31 can be adaptively adjusted based on the diameter of the brush head 31 (corresponding to the length of the windable hair), the material of the hair (whether it is easy to wind), and other conditions.

[0074] According to one embodiment of the present application, as shown in FIGS. 2, 4 and 5, the shearing assembly 10 includes a driving motor 13, the free end of the output shaft 131 of the driving motor 13 is fixed with an eccentric wheel 132, the axis of the output shaft 131 is perpendicular to the axis direction of the brush head 31, corresponding to the two sides of the wheel surface of the eccentric wheel 132 along the axis direction of the brush head 31, the first limiting surface 122 and the second limiting surface 123 are arranged on the second comb blade 12.

[0075] In this embodiment, taking the first limit surface 122 in the drawing as an example, the output shaft 131 of the driving motor 13 drives the eccentric wheel 132 to rotate. Due to the different distances from the different points on the wheel surface of the eccentric wheel 132 to the rotation center, with the rotation of the eccentric wheel 132, the eccentric wheel 132 first abuts against the first limit surface 122 and pushes the first limit surface 122 away from the rotation center of the eccentric wheel 132. At this time, the second comb blade 12 moves in the positive direction along the axis direction of the brush head 31 until it stops at the point on the wheel surface farthest from the rotation center. The output shaft 131 continues to rotate, while the second comb blade 12 does not move until the wheel surface abuts against the second limit surface 123. With the rotation of the eccentric wheel 132, the second comb blade 12 moves in the reverse direction along the axis direction of the brush head 31, thereby realizing the reciprocating motion of the second comb blade 12 and achieving the shearing effect of the teeth of the second comb blade 12.

[0076] In this embodiment, the reciprocating motion of the second comb blade 12 can be realized by the rotation of the driving motor 13 in one direction, thereby effectively reducing the use cost of the driving motor 13.

[0077] In this embodiment, the distance between the first limit surface 122 and the second limit surface 123 is greater than the maximum diameter of the eccentric wheel 132, so that after the first limit surface 122 or the second limit surface 123 contacts the point on the wheel surface of the eccentric wheel 132 farthest from the rotation center, the output shaft 131 continues to rotate, while the eccentric wheel 132 cannot abut against the first limit surface 122 or the second limit surface 123. At this time, the second comb blade 12 is stationary, which ensures that the sheared hair can fall or be sucked by the suction port 321 of the cleaner body 3, thereby avoiding affecting the subsequent shearing effect of the shearing assembly 10.

[0078] Of course, in other embodiments, the reciprocating driving of the second comb blade 12 can also be realized by means of a threaded screw rod, air pressure, hydraulic pressure, etc.

[0079] According to one embodiment of the present application, as shown in FIGS. 4 and 5, the shearing assembly 10 further comprises a support frame 14, which is fixed relative to the protective cover 2. One of the support frame 14 and the second comb blade 12 is provided with a support portion 141, and the other is provided with a support groove 142 matched with the support portion 141. The support portion 141 and the support groove 142 are matched to realize the motion guide of the second comb blade 12 along the axis direction of the brush head 31, and also support the second comb blade 12, thereby avoiding the weight of the second comb blade 12 from pressing on the output shaft 131 of the driving motor 13, which affects the rotation of the output shaft 131.

[0080] In the embodiment, the support frame 14 is provided with a support portion 141, and the second comb blade 12 is provided with a support groove 142. Of course, the second comb blade 12 can be provided with a support portion 141, and the support frame 14 is provided with a support groove 142.

[0081] In the embodiment, the support frame 14 includes two frame bodies 144 that are closed, and the first comb blade 11 and the second comb blade 12 are clamped between the frame bodies 144. The first comb blade 11 and the frame body 144 on one side are provided with a pressing block 145, and the second comb blade 12 and the frame body 144 on the other side are provided with a pressing block 145, so as to ensure the adhesion of the first comb blade 11 and the second comb blade 12 and improve the shearing effect.

[0082] In the embodiment, the support portion 141 includes a plurality of support columns 143 that are arranged in parallel along the axis direction of the brush head 31, and the outer circumferential surface of the support column 143 is in lap joint with the support groove 142. The outer surface of the support column 143 is in line contact with the support groove 142, which is beneficial to reduce the friction between the support column 143 and the support groove 142, ensure the stable operation of the second comb blade 12, and improve the service life of the shearing assembly 10.

[0083] In the embodiment, three support grooves 142 are arranged on the second comb blade 12 in the axis direction of the brush head 31, and three support columns 143 are arranged in each support groove 142. Of course, based on actual requirements, the number of support grooves 142 and the number of support columns 143 arranged in each support groove 142 can be adaptively adjusted.

[0084] According to one embodiment of the present application, as shown in FIG. 8 (only the relative position of the flow guide portion 20 and the protective cover 2 is shown in the figure, and it can be understood that the shearing assembly 10 is arranged below the protective cover 2, and the brush head 31 is located above the flow guide portion 20 and the protective cover 2), the base body 1 is provided with a flow guide portion 20, which is located upstream of the shearing assembly 10 in the rotation direction of the brush head 31. The flow guide portion 20 includes a plurality of helical inclined teeth 201 arranged along the axis direction of the brush head 31, and the helical inclined teeth 201 converge from the brush head 31 to the direction of the shearing assembly 10. The hair on the brush head 31 is guided and concentrated. Specifically, when the length of the movable blade portion 121 of the shearing assembly 10 is less than the length of the brush head 31, the hair on the brush head 31 is guided to the movable blade portion 121 of the shearing assembly 10 through the flow guide portion 20. Thus, the shearing assembly 10 with a shorter length can be used to shear the hair on the brush head 31 with a longer length, thereby effectively reducing the manufacturing cost of the base of the dust collector.

[0085] In this embodiment, as shown in FIG. 8, the flow guide 20 is arranged in parallel with the shearing assembly 10 along the axis direction of the brush head 31. Of course, the flow guide 20 can also be arranged on both sides of the shearing assembly 10, for example, the flow guide 20 is arranged at both ends of the shearing assembly 10 along the axis direction of the brush head 31, and then the hair on both sides of the brush head 31 is concentrated to the shearing assembly 10 at the middle position.

[0086] In this embodiment, the tooth thickness of the helical oblique tooth 201 gradually increases from the tooth top to the tooth root, the tooth top area is reduced to avoid blocking the hair in the rotation direction of the brush head 31, and the spacing between adjacent helical oblique teeth 201 gradually decreases from the tooth top to the tooth root, so as to improve the hair gathering effect.

[0087] According to an embodiment of the present application, as shown in FIGS. 9-12, the base body 1 includes a mounting seat 15, a base 16, and an adjusting piece 17; the mounting seat 15 is fixed with the shearing assembly 10; the mounting seat 15 is suitable for receiving and limiting the cleaner body 3, so that the brush head 31 corresponds to the shearing assembly 10; the mounting seat 15 is movable relative to the base 16, and the adjusting piece 17 is arranged between the base 16 and the mounting seat 15 and is suitable for pushing the mounting seat 15 to move away from the base 16.

[0088] In this embodiment, the user places the cleaner body 3 on the mounting seat, the mounting seat 15 is forced to move towards the base 16, and the adjusting piece 17 provides a reverse pushing force during the movement of the mounting seat 15, so that the mounting seat 15 is always in contact with the cleaner body 3, and then the shearing assembly 10 fixed on the mounting seat 15 is in contact with the brush head 31 of the cleaner body 3, thereby ensuring the shearing effect.

[0089] It should be noted that in the related art, in order to ensure the contact between the shearing assembly 10 and the brush head 31, a technical solution of arranging an elastic piece below the shearing assembly 10 is usually adopted. Since the length of the movable blade part 121 of the shearing assembly 10 is limited, the extension amount of the movable blade part 121 protruding from the mounting seat 15 is also limited, which leads to poor adjustment effect.

[0090] In this embodiment, by arranging the adjusting piece 17 between the mounting seat 15 and the base 16, it is ensured that the shearing assembly 10 on the mounting seat 15 is fixed relative to the brush head 31 of the cleaner body 3 during adjustment, which effectively ensures the shearing effect, and the adjusting piece 17 compensates for the placement error of the cleaner body 3 (as shown in FIG. 9, the cleaner body 3 is hung on the base of the cleaner, and each time it is hung, there will be a certain error), thereby effectively improving the shearing effect.

[0091] In this embodiment, the adjusting piece 17 can be an elastic piece (spring, rubber pad), a plunger rod, or other components with deformation recovery capability.

[0092] According to one embodiment of the present application, as shown in FIGS. 10-12, the base 16 includes a first top wall 161 and a side wall 162, and the mounting seat 15 is covered by the base 16, i.e., part of the inner wall of the mounting seat 15 corresponds to the first top wall 161 of the base 16, and part of the inner wall corresponds to the side wall 162.

[0093] In one embodiment, the first top wall 161 and the inner wall surface of the mounting seat 15 are provided with an adjusting member 17 to adjust the distance between the mounting seat 15 and the base 16 in the vertical direction.

[0094] In one embodiment, the side wall 162 and the inner wall surface of the mounting seat 15 are provided with an adjusting member 17 to adjust the distance between the mounting seat 15 and the base 16 in the horizontal plane. In this embodiment, the side wall 162 is provided with a left wall and a right wall arranged opposite to each other along the axis direction of the brush head 31, and a front wall and a rear wall arranged opposite to each other perpendicular to the axis direction of the brush head 31. Each of the left wall, the right wall, the front wall, and the rear wall is provided with at least one adjusting member 17 to meet the requirement of horizontal distance adjustment of the mounting seat 15 relative to the base 16.

[0095] Of course, the side wall 162 can also be in the form of a circular truncated cone, and the adjusting member 17 can also be adapted to the circular truncated cone to form an elastic circular ring.

[0096] In this embodiment, the side wall 162 of the base 16 surrounds a placement cavity for placing the aforementioned driving motor 13, support frame 14, and other components, thereby improving the integration of the base.

[0097] According to one embodiment of the present application, the adjusting length of the adjusting member 17 ranges from 3 mm to 30 mm, which effectively covers the manufacturing and assembly errors between the components of the vacuum cleaner and ensures the contact between the shear assembly 10 and the brush head 31 within the adjusting range of the adjusting member 17.

[0098] According to one embodiment of the present application, as shown in FIG. 12, the adjusting member 17 is an elastic member, which includes a middle section 171 and two elastic arms 172 fixed to the two ends of the extension direction of the middle section 171 and inclined to the same side of the middle section 171. The free ends of the elastic arms 172 are connected to one of the mounting seat 15 or the base 16, and the middle section 171 is connected to the other.

[0099] In this embodiment, during the movement of the mounting seat 15 towards the base 16, the mounting seat 15 presses the adjusting member 17, the elastic arms 172 of the adjusting member 17 are deformed, and the distance between the free ends of the elastic arms 172 and the middle section 171 is compressed to compensate for the distance between the mounting seat 15 and the vacuum cleaner body 3.

[0100] In this embodiment, the intermediate section 171 is fixed to the base 16, and the free end of the elastic arm 172 is fixed to the mounting seat 15. The specific fixing form can be clamping, screw connection, gluing, etc. Of course, the intermediate section 171 can also be connected to the mounting seat 15, and the free end is connected to the base 16, so as to adjust the relative position between the mounting seat 15 and the base 16.

[0101] According to one embodiment of the present application, as shown in FIG. 12, the mounting seat 15 or the base 16 is provided with a boss 151 corresponding to the intermediate section 171, and the intermediate section 171 is connected with the boss 151 through a fixing member 152 (only a positioning hole is shown in the figure as part of the fixing member 152). The end portions of the intermediate section 171 on both sides of the extension direction extend towards the boss 151 with a reinforcing plate 173. It can be understood that since the mounting seat 15 and the base 16 have horizontal adjustment and vertical adjustment, the horizontal movement of the mounting seat 15 will generate a lateral force on the vertically arranged adjusting member 17, affecting its service life, and the same applies to the horizontally arranged adjusting member 17. That is, the setting direction of the opposite reinforcing plate 173 is perpendicular to the elastic forming direction of the adjusting member 17, thereby improving the ability of the adjusting member 17 adjusted in the vertical direction to resist horizontal deformation, and improving the ability of the adjusting member 17 adjusted in the horizontal direction to resist vertical deformation.

[0102] In this embodiment, a threaded hole can be provided on the boss 151, and the intermediate section 171 is fixedly connected with the boss 151 through a screw. Of course, the aforementioned clamping, gluing, etc. Fixing form can also be used.

[0103] In other embodiments, a boss 151 can also be provided corresponding to the free end of the elastic arm 172, and the principle is the same as above, which can further improve the service life of the adjusting member 17.

[0104] According to one embodiment of the present application, as shown in FIGS. 10 and 11, the mounting seat 15 includes a second top wall 153, which is arranged above the first top wall 161. The second top wall 153 is provided with a through hole 154, which is adapted to pass through part of the shearing assembly 10. The upper surface of the second top wall 153 gradually inclines from the edge to the through hole 154.

[0105] In this embodiment, the whole shearing assembly 10 is hidden below the second top wall 153, and only part of it is exposed through the through hole 154, effectively ensuring the waterproof and dustproof of the shearing assembly 10, and making the upper surface of the second top wall 153 gradually inclined from the edge to the through hole 154. When the user places the dust collector body 3, the inclined upper surface plays a guiding role, optimizing the user's placement experience.

[0106] In this embodiment, the upper surface is irregularly shaped to adapt to the components (such as mobile wheels, main boards 4, etc.) at the bottom of the dust collector body 3

[0107] In one embodiment, as shown in FIG. 10 and FIG. 11, the side of the mounting base 15 away from the base 16 is provided with a ring-shaped protrusion 155, which forms a limiting cavity 156 of the cleaner body 3. The inner wall of the ring-shaped protrusion 155 also serves as a guide when the user places the cleaner body 3, and effectively avoids the vibration caused by the cutting assembly processing the hair on the brush head 31 from causing the cleaner body 3 to disengage from the base of the cleaner.

[0108] In this embodiment, the ring-shaped protrusion 155 is provided corresponding to the outer periphery of the cleaner body 3. Of course, a positioning column can also be provided on the cleaner body 3, in which case the ring-shaped protrusion 155 only needs to be provided corresponding to the positioning column to form the limiting cavity 156 to achieve the limiting of the cleaner body 3 on the mounting base 15.

[0109] According to the second aspect of the present application, the cleaner comprises the base of the cleaner and the cleaner body 3 of the above-mentioned embodiments; the cleaner body 3 can be placed on the base of the cleaner.

[0110] The cleaner according to the embodiments of the present application has the same beneficial effects as the base of the cleaner according to the first aspect of the present application, which will not be described again here.

[0111] According to one embodiment of the present application, as shown in FIG. 6 and FIG. 7, the cleaner body 3 comprises a housing 32 and a brush head 31, and the housing 32 is provided with a suction port 321 corresponding to the contact position of the brush head 31 and the cutting assembly 10, and located downstream of the brush head 31 and the cutting assembly 10 in the rotation direction of the brush head 31.

[0112] In this embodiment, the hair cut by the cutting assembly 10 is sucked into the cleaner body 3 through the suction port 321, and does not accumulate in the base of the cleaner, ensuring the cutting and cleaning effects; and the suction port 321 located on the rear side ensures that the cut hair and the uncut hair are located on both sides of the contact position, and the process of the suction port 321 absorbing the hair does not interfere with the process of the cutting assembly 10 cutting the hair on the brush head 31, effectively ensuring the cutting efficiency and the cleaning effect.

[0113] According to one embodiment of the present application, as shown in FIG. 2, at least one of the cleaner body 3 or the base of the cleaner is provided with a sensor, which is adapted to send a trigger signal when the cleaner body 3 is placed on the base of the cleaner, and the cutting assembly 10 and the cleaner body 3 establish a communication connection in response to the trigger signal.

[0114] In the embodiment, the trigger signal of the inductor establishes the communication connection between the shearing assembly 10 and the cleaner body 3, avoids the false triggering when the cleaner body 3 is not placed on the base of the cleaner, improves the safety, and avoids the idling of the driving motor 13 or the brush head 31 of the shearing assembly 10, saves the power, and effectively reduces the use cost of the cleaner.

[0115] In the embodiment, the inductor can be a microswitch to generate the trigger signal in the form of physical triggering, or can be a Hall inductor to generate the trigger signal in the form of magnetic field induction.

[0116] In the embodiment, the communication connection can be in the form of wireless connection to realize the cooperative control between the cleaner body 3 and the shearing assembly 10. Of course, it can also be in the form of physical connection, such as the electric contacts provided on the base of the cleaner and the cleaner body 3 to realize the electric signal transmission between them. After the electric signal transmission to the mainboard 4 of the base of the cleaner, the mainboard 4 controls the shearing assembly 10 to work, and realizes the cooperative work of the cleaner body 3 and the shearing assembly 10.

[0117] The application also provides a control method of the cleaner. The control method of the cleaner of the embodiment of the application is described below with reference to FIGS. 13 to 15.

[0118] Before introducing the control method of the cleaner of the embodiment of the application, the application scenario of the control method of the cleaner needs to be explained first. The control method of the cleaner of the application can be applied to various types of cleaners provided with the shearing assembly 10 on the base of the cleaner, and can be applied to smart terminals such as smart phones, tablet computers, computers, and can also be applied to servers connected with the cleaner. The application does not specially limit the application scenario, as long as it can carry and realize the control method of the cleaner.

[0119] Among them, the cleaner to which the control method of the cleaner of the application is applied has the cleaner body 3 and the cleaner base, the cleaner body 3 is provided with the brush head 31, and the base of the cleaner includes the base body 1, and the base body 1 is provided with a placement position for placing the cleaner body 3.

[0120] As shown in FIGS. 12 and 15, according to the control method of the cleaner of the embodiment of the application, the control method of the cleaner includes:

[0121] Step 100, determining that the cleaner body 3 is placed on the placement position of the base of the cleaner.

[0122] Wherein, the communication connection between the cutting assembly 10 and the cleaner body 3 can be established by providing an inductor on at least one of the base of the cleaner or the cleaner body 3, the inductor being adapted to send a trigger signal in the case that the cleaner body 3 is placed on the base of the cleaner, and the cutting assembly 10 establishes the communication connection in response to the trigger signal.

[0123] In the embodiment, the inductor can be a microswitch to generate the trigger signal by physical triggering, or a Hall inductor to generate the trigger signal by magnetic field induction.

[0124] In the embodiment, the communication connection can be in the form of wireless connection to realize the cooperative control between the cleaner body 3 and the cutting assembly 10, or in the form of physical connection, such as providing an electrical contact on the base of the cleaner and the cleaner body 3 to realize the electrical signal transmission between the two, and the electrical signal is transmitted to the mainboard 4 of the base of the cleaner to control the cutting assembly 10 to work through the mainboard 4, thereby realizing the cooperative work of the cleaner body 3 and the cutting assembly 10.

[0125] Step 200, the brush head 31 of the cleaner body 3 and the cutting assembly 10 of the base body 1 are simultaneously started.

[0126] The control mode can be manually selected by the user, such as in the form of a control button, and the user selects whether to start the brush head 31 or the cutting assembly 10 based on the actual amount of hair on the brush head 31.

[0127] In the embodiment, the communication connection between the cutting assembly 10 and the cleaner body 3 is established by the trigger signal of the inductor to realize the simultaneous start of the brush head 31 and the cutting assembly 10, avoid the false triggering when the cleaner body 3 is not placed on the base of the cleaner, improve the use safety, and avoid the driving motor 13 of the cutting assembly 10 or the brush head 31 idling, save the power, and effectively reduce the use cost of the cleaner.

[0128] Step 300, the running parameters of the brush head 31 and the cutting assembly 10 are obtained, wherein the running parameters include actual parameters and set parameters.

[0129] The running parameters can be the running time, the current of the driving motor 13, the rotating speed of the driving motor 13, the temperature of the driving motor 13, etc. of the brush head 31 or the cutting assembly 10, the actual parameters in the running parameters are the actual detection values in the working process of the brush head 31 or the cutting assembly 10, and the set parameters are the initial set values of the user or the cleaner factory.

[0130] Step 400, the brush head 31 and the cutting assembly 10 are stopped based on the comparison result of the actual parameters and the set parameters.

[0131] When the actual parameter reaches the set parameter, the hair treatment on the brush head 31 is completed, at which time the brush head 31 and the shearing assembly 10 can be controlled to stop, avoiding idling of the two, and reducing energy consumption.

[0132] According to one embodiment of the present application, before step 200, further comprising:

[0133] Step 500, determining the actual working mode of the dust collector, wherein the dust collector comprises at least two preset working modes, and the actual working mode is one of the preset working modes;

[0134] Different preset modes correspond to different working time of the brush head 31 and the shearing assembly 10, and different rotation speed of the driving motor 13 of the two, and different output power, etc. Specifically, for the case of less hair wound on the brush head 31, a preset mode with short working time and low output power can be selected, while for the case of more hair, a preset mode with long working time and high output power can be used; and for different amounts and materials of hair, a plurality of different preset modes can be set to effectively reduce the operating cost of the dust collector while ensuring the shearing effect.

[0135] Step 300 further comprises step 310 of obtaining the running parameter based on the actual working mode.

[0136] Different actual working modes used to evaluate the completion of hair shearing are different according to the selected different preset modes as the actual working mode, such as the running time of the brush head 31 or the shearing assembly 10 can be used to evaluate the completion of hair shearing, and the current of the driving motor 13 of the brush head 31 or the shearing assembly 10 can also be used to determine.

[0137] According to one embodiment of the present application, the preset working mode comprises a timing mode, the actual parameter of the running parameter is the running time, and the set parameter of the running parameter is the first set time length;

[0138] Step 310 comprises step 311 of determining that the actual working mode is the timing mode, and obtaining the running time and the first set time length.

[0139] Step 400 comprises step 410 of determining that the running time is greater than the first set time length, and stopping the brush head 31 and the shearing assembly 10.

[0140] When the user determines that the amount of hair on the brush head 31 is small, the actual working mode can be selected as the timing mode, at which time the shearing assembly 10 and the brush head 31 run for a certain time length at a certain output power. When the running time reaches the first set time length, it indicates that the hair shearing is completed, and the brush head 31 and the shearing assembly 10 are stopped.

[0141] In this embodiment, the first set duration is two minutes, and the length of the first set duration can be adjusted adaptively based on actual hair cutting needs.

[0142] According to one embodiment of the present application, the preset working mode includes an adaptive mode, the actual parameter of the operation parameter is an actual current of the motor of the cutting assembly 10, and the set parameter of the operation parameter is a set current.

[0143] Step 310 includes step 312 of determining that the actual working mode is the adaptive mode, and acquiring the actual current and the set current.

[0144] Step 400 includes step 420 of determining that the actual current is less than or equal to the set current, and stopping the brush head 31 and the cutting assembly.

[0145] It can be understood that when the cutting assembly 10 keeps running at a constant speed, the output power of the driving motor 13 of the cutting assembly 10 is low in the case of less hair, and the current is small, while the output power of the driving motor 13 of the cutting assembly 10 is high in the case of more hair, and the current is large. Therefore, as the cutting process proceeds, the hair on the brush head 31 gradually decreases, and the current of the driving motor 13 decreases accordingly, until the hair cutting is completed and the minimum current value is reached.

[0146] In this embodiment, the user selects the actual working mode as the adaptive mode, at this time the cutting assembly 10 and the brush head 31 keep running at a certain output power, and as the cutting process proceeds, the current of the driving motor 13 decreases until the set current value is reached, indicating that the hair cutting is completed.

[0147] By detecting the current in the adaptive mode, adaptive cutting effect of different amounts of hair is achieved, the driving motor 13 is prevented from idling in the timing mode, and the use cost of the dust collector is effectively reduced.

[0148] According to one embodiment of the present application, after step 200, the method further includes:

[0149] Step 610: determining that the dust collector body 3 is separated from the placement position, and accumulating the offline duration.

[0150] The determination that the dust collector body 3 is separated from the placement position can be realized by a trigger signal of the inductor, that is, when the dust collector body 3 is separated from the placement position, the inductor sends a trigger signal representing that it is separated from the placement position.

[0151] The accumulation of the offline duration can be realized by using a module with a timing function.

[0152] In this embodiment, the inductor can be in the form of a microswitch or a Hall inductor as described above.

[0153] Step 620, determine the offline duration is greater than the second set duration, control the brush head 31 and the shearing assembly 10 to stop.

[0154] Wherein, when the offline duration is greater than the second set duration, it means that the brush head 31 does not need to perform hair shearing at this time, and the brush head 31 and the shearing assembly 10 are stopped accordingly, avoiding the shearing assembly 10 to continuously run in the case of being exposed to the user, causing a safety hazard, and avoiding the shearing assembly 10 and the brush head 31 to idle, effectively reducing the use cost of the vacuum cleaner.

[0155] According to an embodiment of the present application, step 200 further comprises step 700 of controlling the fan of the vacuum cleaner body 3 to start. The fan guides the sheared hair into the suction port 321, avoiding the accumulation of hair on the shearing assembly 10, affecting the shearing effect of the uncut hair.

[0159] The first acquisition module 930 acquires the operating parameters of the brush head 31 and the shearing assembly 10, wherein the operating parameters include actual parameters and set parameters.

[0160] The second control module 940 is configured to stop the brush head 31 and the shearing assembly 10 based on the comparison result of the actual parameters and the set parameters.

[0161] The control device 900 of the vacuum cleaner according to the embodiment of the present application has the same technical effects as the control method of the vacuum cleaner, which will not be repeated here.
