Disclosure of Invention

It is an aim of embodiments of the present invention to provide an improved cleaning head and cleaning apparatus.

Accordingly, embodiments of the present invention provide a cleaning head comprising a body having a chamber adapted to receive a brush roll, the brush roll being rotatable or relatively movable within the chamber relative to the body, the chamber comprising opposing air inlets and air outlets; the cleaning head further comprises: and the air duct is communicated with the chamber through the air outlet, and the chamber and the air duct are tightened at the air outlet to form a slender transition section. By adopting the scheme of the embodiment, the cleaning effect and the cleaning efficiency of the cleaning appliance can be improved, particularly the cleaning capability to the hair can be improved, the cleaning appliance is easy to clean, the hair cannot be wound on the brush roller basically, and the user does not need to clean the brush roller manually. Specifically, the pressure of the air flowing from the chamber to the air duct is obviously increased when the air passes through the long and narrow transition section, so that when the brush roller moves to a position close to the air outlet with the hairs, most of the air inflow acts on the brush roller, and the hairs are sucked into the air duct. Therefore, the transition section can automatically clean the hair wound on the brush roller during the working process of the cleaning head, the hair is prevented from remaining on the surface of the brush roller, and the trouble of manual cleaning of a user is avoided.

Optionally, the chamber, the transition section and the air duct are 8-shaped on a surface perpendicular to the axial direction of the brush roller. Therefore, a long and narrow transition section serving as a throat is arranged between the upper cavity and the lower cavity, so that the pressure of air at the air outlet is obviously increased, and the hair can be successfully sucked into the air channel when moving to be close to the air outlet along with the brush roller.

Optionally, the area of the cross section of the transition section is smaller than the area of the cross section of the chamber and the area of the cross section of the air duct, wherein the cross section is a plane perpendicular to the direction in which the chamber points to the air duct. Therefore, when the air flows from the chamber with the larger area to the air outlet with the smaller area due to the size change of the cross section, the pressure of the air can be obviously changed, and therefore the hair can be successfully sucked into the air channel when moving to be close to the air outlet along with the brush roller.

Optionally, a junction between the chamber and the transition section is in smooth transition, and/or a junction between the air duct and the transition section is in smooth transition. Therefore, on one hand, the smooth transition design is attractive in appearance and beneficial to manufacturing, and on the other hand, hair accumulation at dead corners in the cleaning head can be avoided.

Optionally, the transition section includes a partition for separating the cavity from the air duct, and the partition is provided with the air outlet. Therefore, the air duct and the cavity can be communicated only through the air outlet due to the existence of the partition plate. An elongated transition area is formed between the chamber and the air duct by designing that the opening of the air outlet formed on the partition plate is smaller than the area of the section of the air duct and the area of the section of the chamber.

Optionally, a ratio of the width of the air outlet to the width of the chamber ranges from 1:4 to 1:8, wherein the width direction is perpendicular to the axial direction of the brush roller and the flowing direction of the air in pairs. From this, through the size ratio of rational design air outlet and cavity for gas pressure can appear obviously changing when gas flows to narrower air outlet from the cavity of broad, thereby ensures that the hair can be successfully inhaled the wind channel when the brush roll moves to being close to the air outlet. The flowing direction of the gas refers to the flowing direction of the gas at the air outlet.

Optionally, the width of the air duct is greater than the width of the air outlet, wherein the width direction is perpendicular to the axial direction of the brush roller and the flowing direction of the air in pairs. The design of the air channel is wide, so that the air channel can be prevented from being blocked by hairs sucked into the air outlet, and the cleaning head can be used for efficiently and continuously cleaning the hairs on the surface of the fabric.

Optionally, the outlet openings extend substantially axially of the roller brush to ensure that any entangled hair from regions of the roller brush is successfully drawn into the outlet openings.

Optionally, the cleaning head further comprises: a handle portion extending in a direction substantially parallel to an axial direction of the brush roller. Therefore, the cleaning head is changed from the prior forward and backward movement along the extending direction of the handle part into the left and right movement, so that the cleaning head is more in line with the human engineering in use, and the user operation is more labor-saving and more convenient.

Optionally, the width of the air inlet is 14 to 20 mm, wherein the width direction is perpendicular to the axial direction of the brush roller and the flowing direction of the air in pairs. The width of the air inlet is not too wide so as to prevent the fabric from being involved in the cleaning process; the width of the air inlet is not too narrow, otherwise the air inlet is easy to interfere with the moving brush roller to influence the cleaning efficiency and damage the brush roller. From this, body and by the design of half the close half of unique adoption of cleaning object surface contact part, the width of air intake is rationally set up according to the radius of rotation when the brush roll moves, can effectively pick up the hair, can avoid again by too much the suction cleaning head of clean surface fabric to cause the brush roll stall or damage by the cleaning object.

Optionally, a plurality of protrusions are arrayed on the circumferential surface of the brush roller, and the tail ends of the protrusions extend out of the chamber from the air inlet. When the protrusions are contacted with the surface of the cleaned object, such as the surface of clothes, the hairs adhered to the surface of the cleaned object can be successfully scraped without excessively pulling the cleaned object, the cleaned object is effectively prevented from being damaged, and the cleaning effect is better. Further, when the brush roller is used to scrape off the hairs adhered to the surface of the object to be cleaned, the protrusions are less likely to be entangled with the hairs or are easily removed based on the design of the transition section even if the hairs are entangled. Therefore, the brush roller does not need to be cleaned frequently and can be reused, and the use cost is reduced. For example, the object to be cleaned may be a fabric, a floor surface, a wall surface, or the like.

The interval is arranged between the adjacent bulges in the plurality of bulges arranged in the array, so that the bulges can further extend into the surface of the cleaned object to effectively remove deep hair. Furthermore, the roots of the protrusions (namely, one ends of the protrusions fixed on the periphery of the brush roller) are not connected, so that the protrusions are easy to deform under the action of external force, the protrusions are convenient to assemble, and the protrusions are softer and not easy to damage the object to be cleaned when contacting the surface of the object to be cleaned, and even if the pet hair on the human body is directly cleaned, the person can not feel pain.

Optionally, the distance that the tail end of the protrusion extends from the air inlet is not less than 0.5 mm, so as to ensure a better hair removal effect.

Optionally, the air inlet and the air outlet are oppositely arranged on two sides of the brush roller along the axial direction of the brush roller, so that hairs brought into the chamber by the brush roller can reach the air outlet in a shortest path and are sucked into the air outlet, and the hairs are prevented from accidentally falling into and accumulating in the chamber.

Optionally, the cleaning head further comprises: and the driving mechanism is suitable for driving the brush roller to move. For example, the drive mechanism may comprise a motor adapted to drive the brush roller to rotate so as to scrape hair off the surface of the object to be cleaned and to be drawn into the chamber with the rotating motion and into the outlet.

Optionally, the body is provided with a heat dissipation port suitable for communicating the space where the driving mechanism is arranged with the outside, so as to avoid motor damage caused by the fact that the driving mechanism (such as a motor) blocks the heat and cannot timely dissipate after the cleaned object is sucked.

Optionally, the cleaning head further comprises: the shifting piece can be plugged into one side of the heat dissipation opening, which is far away from the driving mechanism, and a gap is formed between the shifting piece and the heat dissipation opening. Therefore, on one hand, heat is led out from the interior of the cleaning head and dissipated from the gap to the exterior of the cleaning head, and the interior of the cleaning head, particularly the vicinity of the driving mechanism, is ensured not to accumulate excessive heat; on the other hand, the shifting sheet can cover the heat dissipation port, and is dustproof and attractive. The pluggable design is beneficial to maintenance.

Optionally, the driving mechanism is located above the brush roller along a direction in which the air inlet points to the air outlet. Therefore, along the axial direction of the brush roller, the whole length of the cleaning head is obviously shortened, and the miniaturization design of the product is facilitated.

Optionally, along the axial direction of the brush roller, the length of the air outlet is smaller than that of the air inlet so as to avoid the driving mechanism, and the product miniaturization design is facilitated.

Therefore, the embodiment of the utility model also provides cleaning equipment comprising the cleaning head. The cleaning device provided with the cleaning head has a good effect of removing the hair on the surface of the object to be cleaned, and the removed hair is sucked into the cleaning device basically during cleaning, so that the hair does not remain on the cleaning head, and the user does not need to manually clean the cleaning head. For example, the cleaning device may be a vacuum cleaner and the cleaning head may be a brush of the vacuum cleaner. The dust collector using the cleaning head can effectively remove hair adsorbed and remained on the surface of materials such as woven fabrics, textile fabrics, carpets and the like, and is particularly suitable for removing the hair remained on the surface of clothes worn on the body. Furthermore, the removed hair can be directly sucked into a garbage can of the dust collector by a conductive hose connected to the rear end of the cleaning head, and the brush roller of the cleaning head keeps clean and does not need to be cleaned again.

Detailed Description

As background, existing cleaners and brush heads are inefficient at cleaning hair that is adhered to the surface of the fabric. Even if the hair is successfully removed from the surface of the fabric, the hair can be adhered to the brush head, and the hair can be manually cleaned by a user, so that the operation is complicated.

In order to solve the technical problem, an embodiment of the utility model provides a cleaning head, which comprises a body and a brush roller, wherein the body is provided with a chamber suitable for accommodating the brush roller, the brush roller can rotate or move relative to the body in the chamber, and the chamber comprises an air inlet and an air outlet which are opposite; the cleaning head further comprises: and the air duct is communicated with the chamber through the air outlet, and the chamber and the air duct are tightened at the air outlet to form a slender transition section.

By adopting the scheme of the embodiment, the cleaning effect and the cleaning efficiency of the cleaning appliance can be improved, particularly the cleaning capability to the hair can be improved, the cleaning appliance is easy to clean, the hair cannot be wound on the brush roller basically, and the user does not need to clean the brush roller manually. Specifically, the pressure of the air flowing from the chamber to the air duct is obviously increased when the air passes through the long and narrow transition section, so that when the brush roller moves to a position close to the air outlet with the hairs, most of the air inflow acts on the brush roller, and the hairs are sucked into the air duct. Therefore, the transition section can automatically clean the hair wound on the brush roller during the working process of the cleaning head, the hair is prevented from remaining on the surface of the brush roller, and the trouble of manual cleaning of a user is avoided.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

FIG. 1 is a schematic view of a cleaning head 100 of an embodiment of the present invention; FIG. 2 is a schematic view of the internal structure of the cleaning head 100 shown in FIG. 1; FIG. 3 is a schematic view of the connection between the chamber 111 and the air duct in the internal structure of FIG. 2; FIG. 4 is a cross-sectional view taken along A-A of FIG. 2; FIG. 5 is a bottom view of the cleaning head 100 shown in FIG. 1; fig. 6 is a schematic view of the cleaner head 100 of fig. 1 with the cosmetic housing 116 removed.

In fig. 2, the cosmetic cover 116 (shown in fig. 1) and the housing 117 (shown in fig. 6) are removed from a single side of the cleaner head 100 to clearly show the internal structure of the cleaner head 100. Wherein, the decorative shell 116 is positioned at the outermost layer of the body 110, which plays a role of beauty; the housing 117 is located within the structural support of the cosmetic shell 116 and the cleaner head 100, and a plurality of ribs 118 are provided on the housing 117 for support and protection.

To clearly show the specific structure of the chamber 111, the air duct 114, and the transition section 150 connecting the chamber 111 and the air duct 114, fig. 3 removes the wall of the chamber 111 on the outer side to further show the specific structure of the transition section 150 (especially the air outlet 113). Fig. 4 shows a cross-sectional view of only the chamber 111, the air chute 114, the transition section 150, and the brushroll 120 of fig. 2, taken along the direction a-a. Fig. 5 does not show the brush roller 120.

For convenience of description, in this embodiment, the longitudinal direction of the cleaning head 100 is referred to as the x direction, the width direction of the cleaning head 100 is referred to as the y direction, and the height direction of the cleaning head 100 is referred to as the z direction.

Specifically, referring to fig. 1 to 4, the cleaning head 100 of the present embodiment may include a body 110 and a brush roller 120, the body 110 having a chamber 111 adapted to receive the brush roller 120, and the brush roller 120 being rotatable or relatively movable in the chamber 111 with respect to the body 110.

For example, the brush roller 120 may include a rotation shaft 124, the rotation shaft 124 protruding from one end portion of the brush roller 120 in the axial direction thereof and protruding into the accommodating portion 119 provided in the chamber 111, and the rotation shaft 124 may rotate with respect to the accommodating portion 119. The other end of the brush roller 120 in the axial direction thereof may be provided with a fixing portion 122 for movably fixing the brush roller 120 in the chamber 111. During cleaning, the brush roller 120 is driven by the rotating shaft 124 to rotate relative to the chamber 111, the fixing portion 122 is fixed on the chamber 111 and rotates relative to the chamber 111, and the rotating shaft 124 and the fixing portion 122 rotate synchronously.

For another example, the brush roller 120 may move left and right with respect to the chamber 111 in the axial direction thereof. In this embodiment, the brush roller 120 has an axial direction substantially parallel to the x-direction, and accordingly, the brush roller 120 may reciprocate in the x-direction and the opposite direction with respect to the chamber 111. During the movement of the brush roller 120 relative to the chamber 111, hairs are scraped off from the surface of the object to be cleaned by the brush roller 120 and sucked into the chamber 111. Through the design of the chamber 111 and the transition section 150 to the air duct 114 in this embodiment, the hairs sucked into the chamber 111 can be quickly and completely sucked into the air duct 114 without remaining in the brush roller 120 and the chamber 111.

In one implementation, the thickness of the walls of the chamber 111 may be non-uniform. For example, referring to fig. 4, the walls of the chamber 111 near the widest portion of the brushroll 120 are thinnest to avoid collision with the rotating brushroll 120.

In one implementation, with continued reference to fig. 1-5, the chamber 111 may include opposing intake 112 and exhaust 113 vents. Wherein the inlet 112 is adapted to draw gas from outside the cleaner head 100 into the chamber 111 and the outlet 113 is adapted to allow gas to flow out of the chamber 111 and into other structures inside the cleaner head 100.

Further, the surface of the body 110 with the air inlet 112 can be regarded as the bottom surface of the cleaning head 100, and at least a part of the brush roll 120 extends out of the body 110 from the air inlet 112. When the cleaning head 100 is used to clean an object to be cleaned, the bottom surface is in contact with the surface of the object to be cleaned, and the brush roller 120 can also be in contact with the surface of the object to be cleaned to scrape off hair remaining on the surface of the object to be cleaned. The scraped hair is carried into the chamber 111 with the movement of the brush roller 120.

In one implementation, referring to fig. 4 and 5, the width W of the intake vent 112 may be 14 to 20 mm, wherein the width direction is perpendicular to the axial direction of the brush roll 120 and the flow direction of the gas two by two. The flow direction of the gas refers to the flow direction of the gas at the air inlet 112, and when the air inlet 112 is opened perpendicular to the z direction, the width direction is parallel to the y direction.

In this embodiment, the width W of the inlet 112 is not too wide to prevent the object to be cleaned from being caught in the chamber 111 during cleaning; the width W of the intake opening 112 should not be too narrow, which may interfere with the moving brush roll 120 and affect the cleaning efficiency and damage the brush roll 120.

Therefore, the surface contact part of the body 110 and the cleaned object adopts a unique semi-closed and semi-open design, the width W of the air inlet 112 is reasonably set according to the rotating radius of the brush roller 120 during movement, not only can hair be effectively picked up, but also the phenomenon that the cleaned fabric is excessively sucked into the cleaning head 100 to cause the brush roller 120 to stop rotating or damage the cleaned object can be avoided.

In one implementation, with continued reference to fig. 2-4, the cleaning head 100 may further include a wind tunnel 114 in communication with the chamber 111 through the wind outlet 113, and the chamber 111 and the wind tunnel 114 converge at the wind outlet 113 to form an elongated transition 150.

Specifically, the transition section 150 is adapted to connect the chamber 111 and the air chute 114 and to provide a transition. The junction of the transition section 150 and the chamber 111 may be understood as an air outlet 113 of the chamber 111, and the junction of the transition section 150 and the air duct 114 may be understood as an air inlet of the air duct 114.

Further, referring to fig. 3, the elongated shape may mean that the width of the air outlet 113 in the y direction is smaller than the width of each of the chamber 111 and the duct 114 in the y direction. Further, referring to fig. 5, the width of the outlet 113 in the y direction may be even smaller than the width W of the inlet 112.

When the cleaning head 100 is used to clean an object to be cleaned, the brush roller 120 protruding from the inlet 112 contacts the surface of the object to be cleaned and scrapes off hairs adhered to the surface of the object to be cleaned, and the scraped-off hairs are brought into the chamber 111 and gradually come close to the outlet 113 along with the rotational movement of the brush roller 120. The pressure near the air outlet 113 having the transition section 150 is increased, and the air inflow sharply increased is substantially applied to the brush roller 120 which is rotationally moved to the vicinity of the air outlet 113 to suck the hairs thereon, and the sucked hairs enter the air duct 114 through the air outlet 113. Thus, the hair scraped from the surface of the object to be cleaned is automatically sucked into the air duct 114 without remaining on the surface of the brush roller 120, and the whole process does not require manual intervention of the user.

Thereby, the cleaning effect and the cleaning efficiency of the cleaning appliance (such as the cleaning head 100) can be improved, especially the cleaning ability to the hair can be improved, and the cleaning appliance itself is easy to clean, and the brush roller 120 is not wound with the hair basically without being cleaned manually by the user. Specifically, the pressure of the air flowing from the chamber 111 to the air duct 114 is increased significantly when passing through the elongated transition section 150, so that when the brush roller 120 moves to a position close to the air outlet 113 with the hairs, most of the intake air acts on the brush roller 120 to suck the hairs into the air duct 114. Thus, the transition section 150 can automatically clean the hair wound on the brush roll 120 during the operation of the cleaning head 100, so that the hair is prevented from remaining on the surface of the brush roll 120, and the trouble of manual cleaning of a user is avoided.

In one implementation, the thickness of the transition section 150 in the z-direction may be substantially equal to the thickness of the walls of the chamber 111, i.e., the chamber 111 and the duct 114 are directly connected and form the transition 150 where they converge. At this time, when viewed from a plane formed by the y-direction and the z-direction (i.e., a plane perpendicular to the axial direction of the brush roller 120), referring to fig. 4, the chamber 111, the transition section 150, and the air duct 114 are formed in a shape of 8, the chamber 111 and the air duct 114 respectively form two upper and lower circles of the shape of 8, and the transition section 150 forms a portion where the two upper and lower circles meet.

Accordingly, the air flows out from the air outlet 113 of the chamber 111 and then enters the air duct 114 through the air inlet of the air duct 114.

Therefore, a narrow transition section 150 serving as a throat is arranged between the upper and lower wide cavities, so that the pressure of air at the air outlet 113 is obviously increased, and the hair can be successfully sucked into the air duct 114 when moving to be close to the air outlet 113 along with the brush roller 120.

In one variation, the thickness of the transition section 150 in the z-direction may be increased, i.e., the transition section 150 extends a distance toward the air duct 114 to increase the spatial area for higher pressure. At this time, the air flows out from the air outlet 113 of the chamber 111, flows through a long and narrow channel with a certain length, and then enters the air duct 114 through the air inlet of the air duct 114.

In one implementation, referring to fig. 2-5, the area of the cross-section of the transition section 150 may be less than the area of the cross-section of the chamber 111, and the area of the cross-section of the transition section 150 may be less than the area of the cross-section of the air chute 114. Here, the cross section refers to a plane (i.e., a plane formed by the x direction and the y direction) perpendicular to the direction in which the chamber 111 points to the air duct 114.

Specifically, referring to fig. 2 and 3, the length of the transition section 150 in the x-direction may be less than the length of the chamber 111 in the x-direction.

Further, referring to FIG. 4, the width of the transition section 150 in the y-direction may be less than the width of the chamber 111 and the width of the wind tunnel 114 in the y-direction.

Therefore, when the air flows from the chamber 111 with a larger area to the air outlet 113 with a smaller area due to the size change of the cross section, the pressure of the air is obviously changed, so that the hair can be successfully sucked into the air channel 114 when moving to be close to the air outlet 113 along with the brush roller 120.

In one implementation, the junction of the chamber 111 and the transition section 150 may be rounded. For example, referring to fig. 4, the inner wall of the chamber 111 may be smoothly extended to the outlet 113 without a break angle.

Further, referring to fig. 3, the transition section 150 may include a partition 151 provided with the air outlet 113, where the partition 151 is disposed between the air duct 114 and the chamber 111 and is used to divide the air duct 114 and the chamber 111 into two independent cavities. The existence of the partition 151 enables the air duct 114 and the chamber 111 to communicate only through the air outlet 113, and by designing the opening of the air outlet 113 formed in the partition 151 to be smaller than the area of the cross section of the air duct 114 and the area of the cross section of the chamber 111, a long and narrow transition region is formed between the chamber 111 and the air duct 114.

The junction of the chamber 111 and the baffle may be rounded.

While the connection between the air duct 114 and the partition may be non-smooth, referring to fig. 4, the air duct 114 may be directly mounted on the partition 151.

In one variation, the junction between the air chute 114 and the transition section 150 may also be rounded.

Therefore, on one hand, the smooth transition design is attractive in appearance and beneficial to manufacturing, and on the other hand, hair accumulation at dead corners in the cleaning head 100 can be avoided.

In one embodiment, the ratio between the width of the outlet 113 and the width of the chamber 111 may range from 1:4 to 1:8, wherein the width direction is perpendicular to the axial direction of the brush roller 120 and the flow direction of the gas two by two. The flow direction of the gas is the flow direction of the gas at the outlet 113, and when the outlet 113 is opened perpendicular to the z direction, the width direction is parallel to the y direction.

Therefore, by reasonably designing the size ratio of the air outlet 113 to the chamber 111, the air pressure is obviously changed when the air flows from the wider chamber 111 to the narrower air outlet 113, so that the hair can be successfully sucked into the air duct 114 when the hair moves to be close to the air outlet 113 along with the brush roller 120.

Further, the width of the air duct 114 may also be larger than the width of the air outlet 113. Therefore, the design of the air duct 114 is wide, which is beneficial to preventing the air duct 114 from being blocked by the hair sucked into the air outlet 113, and ensuring that the cleaning head 100 can efficiently and continuously clean the hair on the surface of the fabric.

In practical application, the ratio range between the width of the air outlet 113 and the width of the cavity 111 can be adjusted reasonably according to the air speed when the air flows.

In one embodiment, referring to fig. 2, 3 and 5, the air outlet 113 extends substantially along the axial direction of the brushroll 120 to ensure that any hair entangled with regions of the brushroll 120 is successfully drawn into the air outlet 113. That is, in this embodiment, the outlet 113 extends substantially along the x-direction.

For example, the length of the air outlet 113 in the x direction may be equal to the length of the brush roll 120 in the axial direction thereof, so as to ensure that hairs brought into the chamber 111 from any region during the rotational movement of the brush roll 120 can be effectively sucked into the air passage 114.

For another example, referring to fig. 2, 3 and 5, the length of the outlet 113 in the x direction may be slightly shorter than the length of the brush roller 120 in the axial direction thereof to make room for the motor 141, so that the internal structure of the cleaning head 100 is more compact and the overall size of the cleaning head 100 is reduced.

In one implementation, with continued reference to fig. 1, 2, 5, and 6, the cleaning head 100 may include a handle portion 130, the handle portion 130 extending in a direction substantially parallel to an axial direction of the brushroll 120. That is, the handle portion 130 may be substantially elongated along the x-direction.

Therefore, the use of the cleaning head 100 is changed from the prior forward and backward movement along the extending direction of the handle part 130 to the left and right movement, so that the use of the cleaning head 100 is more in line with the human engineering, and the operation of a user is more labor-saving and more convenient.

Specifically, the axis of the handle 130 extending substantially in the x direction is parallel to the axis of rotation of the brush roller 120, so that the user can operate the cleaning head 100 to clean the object by holding the handle 130, and the user can clean the surface of the object by moving the body 110 left and right (i.e., moving in the y direction and the opposite direction). This process is similar to the process in which a user wears a comb, and the user can operate the cleaning head 100 with one hand, which is convenient for the user to have one person belly clean the hair remaining on the surface of the object to be cleaned.

Further, the elongated transition section 150 allows the design direction of the air duct 114 to substantially coincide with the extending direction of the handle portion 130. Thus, the extending directions of the intake vent 112, the chamber 111, the exhaust vent 113, the wind tunnel 114, and the handle portion 130 are kept consistent and substantially on the same line in the z-direction. On the one hand, the hairs sucked into the chamber 111 can move to the wind channel 114 with the shortest line of motion, and on the other hand, the user can hold the cleaning head 100 left and right in the y direction to perform the cleaning operation.

In one embodiment, referring to fig. 2 and 4, the brush roller 120 may have a plurality of protrusions 121 arrayed on the circumference thereof, and the ends 121a of the protrusions 121 extend out of the chamber 111 from the inlet 112.

Specifically, the protrusion 121 may be in a shape of a column or a long rubber granule, and the protrusion 121 has a root portion 121b and a terminal portion 121a opposite to each other in an extending direction thereof, the root portion 121b is an end of the protrusion 121 fixed to the circumferential surface of the brush roller 120, and the terminal portion 121a is an end of the protrusion 121 away from the circumferential surface of the brush roller 120.

Alternatively, the ends 121a of the protrusions 121 may be hook-shaped to better catch the hair.

More specifically, the length of the protrusion 121 in the extending direction thereof may be slightly larger than the diameter thereof, for example, the aspect ratio of the protrusion 121 may be larger than 5. Here, the length of the protrusion 121 in the extending direction thereof refers to the distance from the root portion 121b to the tip portion 121 a.

When the axial direction of the brush roller 120 is substantially parallel to the x-direction, the extending direction of the protrusions 121 may be substantially parallel to the z-direction.

Further, the protrusion 121 may be made of an elastic material. For example, the protrusions 121 may be a thermoplastic elastomer, such as vulcanized rubber.

The Shore a hardness (also called Shore A) of the protrusions 121 may be 20 to 35 degrees to ensure that the brush roller 121 can effectively clean hair under high-speed rotation and also ensure that the protrusions 121 do not cause pain when being hit on the body.

Therefore, when the protrusions 121 contact with the surface of the object to be cleaned, such as the surface of clothes, the hairs adhered to the surface of the object to be cleaned can be successfully scraped without excessively pulling the object to be cleaned, the object to be cleaned is effectively prevented from being damaged, and the cleaning effect is better. Further, when the brush roller 120 is used to scrape off the hairs adhered to the surface of the object to be cleaned, the protrusions 121 are less likely to be entangled with the hairs or are easily removed even if the hairs are entangled, based on the design of the transition section 150. So that frequent cleaning of the brush roller 120 is not required and the brush roller 120 is reusable, which is advantageous for reducing the use cost. For example, the object to be cleaned may be a fabric, a floor surface, a wall surface, or the like.

Further, with continued reference to fig. 2, the protrusions 121 are spaced apart from each other such that the protrusions 121 can further extend into the surface of the object to be cleaned to effectively remove deep hair. Furthermore, the roots 121b of the protrusions 121 are not connected and are easily deformed by external force, so that the protrusions 121 are more flexible and less prone to damage the object to be cleaned when contacting the surface of the object to be cleaned, and the pet hair on the human body can be cleaned directly without causing pain.

Further, the specific arrangement of the plurality of protrusions 121 arranged in an array on the circumferential surface of the brush roller 120 may include: the brush roller 120 is provided with protrusions 121 in rows on the circumferential surface thereof, each row of the protrusions 121 is referred to as a row of protrusions 121, and the extending direction of the row of protrusions 121 is substantially parallel to the axial direction of the brush roller 120. Further, a plurality of rows of protrusions 121 are provided at intervals on the circumferential surface of the brush roller 120 in the circumferential direction of the brush roller 120. Each row of protrusions 121 comprises a plurality of protrusions 121 spaced apart from each other by a distance different from zero.

Further, the protrusions 121 may be integrally formed with the body of the brush roller 120. Alternatively, the protrusions 121 may be fixed to the circumferential surface of the brush roller 120 by means of adhesion or the like.

Further, with continued reference to fig. 2 and 4, the distal end 121a of the protrusion 121 protrudes from the air inlet 112 by a distance of not less than 0.5 mm to ensure superior hair removal.

For example, the ends 121a of the protrusions 121 may protrude from the air inlet 112 by about 1 mm to ensure that the brush roller 120 can effectively contact the object to be cleaned during the use of the cleaning head 100, thereby scraping off the hair on the surface of the object to be cleaned based on the protrusions 121.

In one embodiment, the circumferential surface of the brush roller 120 may further be provided with ribs 123, and the ribs 123 and the plurality of protrusions 121 are alternately disposed on the circumferential surface of the brush roller 120 along the circumferential direction of the brush roller 120.

Specifically, the ribs 123 may include ribs protruding outward from the circumferential surface of the brush roller 123.

The ribs 123 may further include recesses that are recessed inward from the circumferential surface of the brush roller 123.

Therefore, the design of the ribs 123 enables the circumferential surface of the brush roller 120 to be concave-convex, even a small amount of hair is wound around the brush roller 120, the circumferential surface of the brush roller 120 cannot be completely attached, and the subsequent cleaning operation of the brush roller 120 is facilitated.

Further, the ribs 123 are alternately arranged with the respective rows of protrusions 121 in the circumferential direction of the brush roller 120. That is, a row of protrusions 121 is disposed between two adjacent ribs 123.

Further, the distance from the ribs 123 to the two adjacent rows of protrusions 121 may be the same or different along the circumferential direction of the brush roller 120.

Further, the ribs 123 and the plurality of rows of protrusions 121 may be non-uniformly alternately disposed on the circumferential surface of the brush roller 120 in the circumferential direction of the brush roller 120. For example, one or more ribs 123 may be disposed between the partial row of protrusions 121, and no rib 123 may be disposed between the partial row of protrusions 121.

In one embodiment, the single row of protrusions 121 may extend in a zigzag, V-shaped, wavy, or arc shape along the axial direction of the brush roller 120.

Further, the ribs 123 may also be in a zigzag shape, a V shape, a wave shape, or an arc shape along the axial extending direction of the brush roller 120.

Further, the length of the ribs 123 in the extending direction thereof may be equal to the length of the single row of protrusions 121.

In one embodiment, with continued reference to fig. 2-4, the air inlet 112 and the air outlet 113 are oppositely disposed on two sides of the brush roll 120 along the axial direction of the brush roll 120, so that hairs brought into the chamber 111 by the brush roll 120 can reach and be sucked into the air outlet 113 with a shortest path, which is beneficial to prevent the hairs from accidentally falling and accumulating in the chamber 111.

In one implementation, with continued reference to FIG. 2, the cleaning head 100 may include a drive mechanism 140 adapted to drive the brushroll 120 in motion.

For example, the driving mechanism 140 may include a motor 141 adapted to drive the brush roller 120 to rotate so as to scrape off the hairs on the surface of the object to be cleaned and to be drawn into the chamber 111 into the outlet 113 along with the rotating motion.

For example, the motor 141 may be a rotary motor.

Further, the driving mechanism 140 may further include a driving belt 142 adapted to connect the motor 141 and the rotation shaft 124 of the brush roll 120 to transmit the rotational driving force of the motor 141 to the rotation shaft 124.

In one implementation, the drive mechanism 140 may be positioned above the brushroll 120 in a direction in which the intake vent 112 is directed toward the exhaust vent 113 (i.e., in the z-direction). For example, the motor 141 is located above the brush roller 120. Thus, the overall length of the cleaning head 100 in the axial direction (i.e., x-direction) of the brush roller 120 is significantly shortened, facilitating a product compact design.

Further, referring to fig. 2 and 5, along the axial direction of the brush roller 120, the length of the air outlet 113 is smaller than that of the air inlet 112 to avoid the driving mechanism 140, which is beneficial to the miniaturization design of the product. For example, the air duct 114 and the motor 141 may be provided side by side in the x direction above the brush roller 120 in the z direction.

In one embodiment, with reference to fig. 6, the body 100 may be provided with a heat dissipating opening 115 adapted to communicate the space where the driving mechanism 140 is disposed with the outside, so as to prevent the motor 141 from being damaged due to the fact that the driving mechanism 140 (such as the motor 141) cannot dissipate heat in time after the cleaned object is sucked.

Specifically, the heat dissipation opening 115 may be opened at a position of the housing 117 corresponding to the motor 141 to guide heat generated at the motor 141 out of the body 110.

Further, the cosmetic housing 116 and the housing 117 may be separated by a gap based on ribs 118 so that heat at the heat dissipation opening 115 is further conducted out of the cleaning head 100 from the gap.

Further, the cosmetic cover 116 covers the heat dissipation opening 115 such that the heat dissipation opening 115 is not visible to the user from the overall appearance of the cleaning head 100.

In one implementation, with continued reference to fig. 1 and 6, the cleaning head 100 may include a pull tab 160 that is removably disposed on a side of the heat sink 115 facing away from the driving mechanism 140, and a gap exists between the pull tab 160 and the heat sink 115.

Specifically, the decorative cover 116 and the housing 117 are provided with openings at the ends of the body 110 in the x direction (i.e., the side walls of the body 110), through which the paddle 160 can be inserted and cover the heat dissipation ports 115, as shown in fig. 6. The paddle 160 may also be pulled out of the opening.

Further, in the y-direction, there is also a gap between paddle 160 and heat sink 115 to conduct heat away from the vicinity of motor 141.

Thus, on the one hand, heat is conducted away from the interior of the cleaner head 100 and dissipated from the gap to the exterior of the cleaner head 100, ensuring that no excessive heat build-up occurs within the cleaner head 100, particularly in the vicinity of the drive mechanism 140; on the other hand, the shifting piece 160 can cover the heat dissipating opening 115, so that the dustproof and beautiful effects are achieved. The pluggable design is beneficial to maintenance.

Embodiments of the present invention also provide a cleaning apparatus, including the cleaning head 100 shown in fig. 1 to 6.

For example, the cleaning device may include a vacuum cleaner, the handle portion 130 may be hollow, and the hollow portion communicates with the air chute 114. When the vacuum cleaner is in operation, air containing dust is sucked in through the air inlet 112, and the sucked air containing dust is transmitted to a dust filter bag (not shown, also called a trash can) of the vacuum cleaner through the chamber 111, the air outlet 113, the air duct 114 and the handle portion 130 in sequence. The brush roller 120 rotated by the motor 141 scrapes the hair on the surface of the object to be cleaned while sucking air. When the scraped hair is brought near the air outlet 113 by the protrusion 121, the scraped hair is sucked into the air outlet 113 along with the air flow, and finally enters the trash can through the air duct 114 and the handle portion 130.

Further, the handle portion 130 includes a locking mechanism 131 for connecting to or disconnecting from an electrically conductive hose (not shown) of the cleaner to secure or remove the cleaner head 100 to or from the cleaner.

Thus, the cleaning device with the cleaning head 100 shown in fig. 1 to 6 has a good effect of removing the hair on the surface of the object to be cleaned, and the removed hair is sucked into the cleaning device during the cleaning process, and the hair does not remain on the cleaning head 100, so that the user does not need to clean the cleaning head 100 manually.

For example, the cleaning device may be a vacuum cleaner and the cleaner head 100 may be a brush cleaner of the vacuum cleaner. The vacuum cleaner using the cleaning head 100 can effectively remove the hair adsorbed and remained on the surface of materials such as woven fabrics, textile fabrics and carpets, and is particularly suitable for removing the hair remained on the surface of clothes worn on the body. Further, the removed hairs can be directly sucked into the dust container of the cleaner by the conductive hose connected to the rear end of the cleaning head 100, and the brush roller 120 itself of the cleaning head 100 is kept clean without being cleaned again.
