The effectiveness of the vacuum cleaner will depend on the amount of dirt and dust that the cleaning head can pump to the dirt and dust separation device from 200826892. For each vacuum cleaner, there is an optimum configuration for the relationship between the dirty air inlet and the carpet to be cleaned. In general, this relationship would be to maintain the dirty air inlet in a plane parallel to the floor of the building. The mouth of the inlet is horizontal. In the ideal state, the inlet or dirty air inlet should be maintained at a level above the floor (or at an optimal angle or configuration) so that it is sucked into the dirty air inlet. The maximum amount of air passes through the fibers of the carpet being cleaned before passing through the cleaning head to the dirt and dust separation device. However, when the vacuum cleaner is used on different types of floor surfaces, such as carpets having different plush and texture structures, clear The inclination angle of the head 10 may be different for the surface. In addition, the vacuum cleaner is moved in a reciprocating forward movement on the surface to be cleaned in use, so that the cleaning head advances and retreats on the surface while collecting dirt and through the dirty air inlet. Dust. In most cases, the cleaning head will be applied differently by the floor when traveling in different directions, and will not maintain good contact on all sides of the dirty air inlet in both directions. Also, in normal use The action of the user can cause the handle to tilt the viewing direction in a significantly significant manner, and this can cause the plane of the dirty air inlet to be lifted out of the optimal configuration at the front or rear. A separate brush motor on the cleaning head The weight and mounting arrangement may also cause the cleaning head to not maintain good contact with the surface to be cleaned and deviate from the optimal configuration of the dirty air inlet. Any one or both of these things can result in suction effectiveness of the cleaning head. Lowering, this can result in a loss of the highest level of suction and thus dissatisfaction to the consumer. There have been many cleaning by manual operation. The head lifting mechanism allows the user to attempt to solve this problem by setting the cleaning head to an optimum height of 200828892 degrees when the vacuum cleaner is used on a particular surface. However, these mechanisms are only connected to the vacuum cleaner body by means of a cleaning head. The axis pivots centrally to lift the cleaning head. These methods do not address the dirty air inlet becoming deviated from the optimal configuration and thus making the inlet suction less effective. An effective way to solve this problem has been disclosed in 5 EP1043947 A cradle-type arrangement for mounting a brush strip in a dirty air inlet is disclosed. The brush strip is mounted to a cradle that is itself rotatably mounted in the cleaning head. The difficulty associated with this arrangement is that the cradle must This is related to cleaning head seals and is difficult to achieve. EP 1119282 solves this problem unidirectionally and discloses a cleaning head assembly that is dually articulated with respect to the body of the vacuum cleaner 10. This allows the brush casing to float freely on the surface to be cleaned even when the angle of inclination of the handle of the cleaner is changed during use. However, continuous movement and in some cases the weight of the motor on the brush strip can cause the brush casing to be lifted off the floor surface. This is not what we want, because the suction of the inlet becomes less effective. 15 One object of the present invention is to provide a cleaning head that maintains the suction port of the dirty air inlet in contact with the surface to be cleaned throughout the cleaning operation. Another object of the present invention is to maintain the dirty air inlet in a substantially horizontal plane, the type of carpet being cleaned, the direction of movement of the cleaning head, the weight of any motor mounted on the brush housing, and the vertical direction of the handle. The tilt angle is irrelevant. Maintaining the dirty air inlet 20 in a horizontal plane ensures that a good, evenly distributed airflow passes through the inlet and the brush strip. This will improve the suction performance of the cleaning head assembly. Still another object of the present invention is a cleaning head for use with a vacuum cleaner and having a stronger suction capability. SUMMARY OF THE INVENTION 9 200826892 The present invention provides a cleaning head assembly as claimed in the scope of the patent application. The invention also proposes a vacuum cleaner according to item 15 of the patent application. The preferred features are presented in the sub-items. The cleaning head assembly in accordance with the present invention is associated with the dual attachment 5 of the cleaner body and an elastic member biases the brush housing to urge the rear portion of the brush housing in a direction corresponding to the cleaning head body. The suction opening in the brush housing thus remains substantially optimally configured, i.e., level, and the suction performance of the vacuum cleaner is enhanced. The brush casing is biased to contact the surface to be cleaned, and the force of the brush casing and any motor for the brush bar is θ10, and the force or weight tends to be during the normal forward movement of the vacuum cleaner. The front of the brush housing is lifted off the surface to be cleaned. The preferred arrangement of the brush housing relative to the cleaning head body pivoting about an axis that coincides with the axis of the brush strip is a convenient and easy to manufacture configuration. An elastic member is preferably provided between the brush housing and the cleaning head body to counteract any lifting force acting on the brush housing. Preferably, the resilient member acts between the cleaning head and the brush housing to pull the rear brush housing up. More preferably, the resilient member is provided between the cleaning head body and a rear portion of the brush housing and ensures that the suction port of the dirty air inlet is in constant contact with the surface to be cleaned at all times. This ensures reliable operation of the organization. The elastic member is preferably a pull spring. A flat motor can be provided on the brush housing and configured to drive the brush strip. In the case of the car father, a flashing piece is provided to enhance the sealing action of the suction port and the surface to be cleaned, and more preferably a support piece or a carpet piece is provided to enhance the ability of the cleaning head assembly to pick up debris from the carpet. .

The head assembly 1〇8 includes a brush housing 11〇 housing: the ear (not shown) can be inserted into the fairy: 22 ‘ : σ1Μ2. The brush casing U is made of an upper plate 20 and a lower steel, and the upper and lower plates may be made of a plastic material or a metal such as a stainless steel k. The upper and/or lower plates may be transparent. "The upper and lower plates 20, 22 are joined by a right angle swivel tie (not shown), the straw is press-fitted or by other suitable means. - the seal is clamped on, and the lower plate 20, 22 to ensure that the seal between the plates 2, 22 is airtight. The roller 25 is rotatably mounted on the front edge of the lower plate 22 to support the brush casing 110 on the carpet or other surface to be cleaned. It may be positioned at or near the outer edge of the lower surface 22, or may extend continuously or in a spaced manner over the full width of the brush housing 110. An air inlet 112 is formed in the lower plate 22. The air inlet H2 extends from the brush The full width of the casing 110. A brush strip 26 is rotatably mounted in the brush casing 11 so that the bristles 27 of the 2 bristles 26 slightly protrude beyond the suction port 112. The axis B of the center of rotation of the brush strip is brushed The housing 11 is coincident with an axis pivotally mounted on the front portion 12 of the cleaning head body 10. The brush strip 26 is configured to be movable by a brush motor, such as via a direct drive train mechanism. Other transmission mechanisms and arrangements are also It is feasible, for example, to set the brush bar to be movable by a motor of the vacuum cleaner 1 through a 13 2 00826892 The drive belt is driven. The upper plate 20 of the brush casing 110 has a connection port 28 for connecting the brush casing 110 to an air inlet on the main body of the cleaner 100. A hook-like projection 34 is provided on the front portion 12 of the cleaning head body 10. The rear of the inner surface of the inner surface of the inner surface of the inner surface of the brush body 110 is also provided. The eye protrusion 5 is also provided on the upper surface of the lower plate 22 of the brush casing 110. Prior to the hooked projection 34, the eyed projection 36 is positioned below the axis B on which the brush housing 110 is pivotally mounted on the cleaning head body 10. The hooked projection 34 is positioned at the axis B. Above, an elastic member 38 extends between the hook protrusion 34 and the eye protrusion 36. The elastic member 38 takes the form of a tension magazine. The suction port 112 of the lower plate 22 is substantially rectangular and has side walls 52, 54. And the end walls 56 and 58 are defined. An arm 50 extends rearwardly from the wall 52 of the front section of the suction port 112 to the wall 54 of the rear section of the suction port 112. The inner surface of the arm 50 is serpentine or includes a strip adapted to receive the brush strip 26. Let the bristles of the brush strip slightly protrude the suction port 112 to replace the shape outside the 15th. In the embodiment, more than one arm 50 is provided, preferably four. The arm 50 may be made of a plastic material or a metal such as stainless steel. A preferred embodiment is shown in Figures 6 and 7. One of the first ends 51 of the arms 50 is joined to the suction. The front end of the port 112. The second end 53 of one of the arms 50 is joined to the rear of the suction port 112. The ends 51, 53 are joined to the walls 20 52, 54 of the suction port and to the wall 52 at substantially the same height and height from the ground. 54 is flushed. A portion 70 of the arm 50 extends from the plane of the suction port toward the surface to be cleaned. A cross-sectional view (Fig. 7b) of a point in the axis A of the arm 50 is shown in the shape and part of the arm. 70 details. Figures 7c and 7d show cross-sectional views of the arm 50 taken along the axis B-B of the portion 70 and the axis C-C at the lower portion of the arm 50. 14 200826892 The arm 50 is shaped to have a cross-section that gradually and smoothly changes from the front section of the intake port 112 to the rear section of the intake port 112. In use, the outer surface of the arm 50 closest to the surface to be cleaned presents a surface that is shaped and dimensioned to facilitate movement of the brush housing 110 and cleaning head 108 over the surface to be cleaned. An arm 50, also referred to as a carpet or support member, allows the brush housing 110 to be trapped within the long pile carpet but supported on a hard surface or short pile carpet. Therefore, the suction port will pull the lower plate 22 away from a hard surface by the sculpt arm so as not to be pulled down by the excessive suction force acting on the hard surface, and the cleaner again retains a good suction performance. A sealing member 40 is provided at the rear of the brush housing. Figures 4, 5 and 6 show in more detail the brush housing 110 and sealing member 40 which form part of the vacuum cleaner shown in Figures 1 and 2. The operation of the sealing member 40 will be explained below. The resilient member 38, the arm 50 and the sealing member 40 function together to enhance the suction performance and cleaning efficiency of the vacuum cleaner. 15 Figure 3 illustrates the orientation of the cleaning head assembly 108 on a surface such as a carpet, particularly a long pile carpet. The bristles 27 of the brush strip 26 slightly protrude from the outside of the suction port 112 into the carpet pile and the cooperation of the carpet pile and the bristles helps maintain a gap between the surface to be cleaned and the brush casing, which allows for a larger break. The chips enter the air inlet. In the preferred embodiment, the gap is at most 3 匪. The 20 preferred spacing provides an opening sufficient to allow dirt, dust and large debris to be drawn into the air inlet while maintaining a high suction performance. Figure 5 illustrates the orientation of the non-brushing housing 110 on a surface such as a hard or short woven carpet. Figure 5 shows that the upward force exerted by the resilient member 38 on the brush housing 110 is greater than the downward force applied by the brush motor and motor housing 114 to the rear portion of the brush housing 110 15 200826892. On a lint carpet, the bristles 27 of the brush strip 26 are not supported by the carpet pile as in the case of Figure 3. This means that suction can be used to push the front section of the suction port 112 into the surface and effectively block the dirt and debris from the front of the air inlet and the suction port. The rotation of the brush casing produces a gap in the rear of the suction port 112, which further deteriorates the performance of the cleaning head. The gap can be sealed by a sealing member. The sealing member 40 is located near the suction port 112 and extends across the full width of the suction port 112. The sealing member first portion 42 is positioned in the slot 46 of the lower plate 22. The first portion 42 is secured in the slot 46 by any suitable means. The second portion 44 of the seal 10 member 40 extends from the first portion and is positionable in a first position (shown in FIG. 3) adjacent to a lower surface of the lower plate 22 and a second position extending downward from the brush housing 110. Move freely between. The sealing member 40 is mounted on the lower plate 22 of the brush housing 110 such that a free end 45 can protrude below the suction port 112. 15 The sealing strip 40 is moveable between the first position and the second position by any suitable means. It can be moved by a rotatable connection located in the brush housing. Alternatively and preferably, the sealing member comprises a resiliently deformable material such as a rubber or plastic material. Therefore, the sealing member can be bent and shaped to be flush with the lower plate 22 as shown in FIG. The sealing member can also be deformed to a substantially flat orientation as shown in FIG. This helps the suction port seal and maintains the performance of the cleaning head. The function of the elastic member 38 is to bias the brush casing 11 in a clockwise direction so that the rear portion of the brush casing 110 is raised. At all times, the tension spring 38 acts between the brush housing 110 and the cleaning head body 10 to bias the rear portion of the brush housing 16 200826892 upward. The rear portion of the brush casing 110 is thus biased against the weight of the motor casing and motor and remains in contact with the surface to be cleaned. It also counteracts any lifting forces that would otherwise cause the front portion of the brush housing 110 to be lifted off the surface to be cleaned. A lifting force may be applied to the brush casing 110 due to a thick pile carpet or lifting force such as due to large debris or friction. Further, since the flexible tube 32 is made of a plastic material, the tube 32 may apply some force to the rear portion of the brush housing 110 in the normal use of the vacuum cleaner 100 in some cases. The resilient member is designed to counteract the downward force applied to the rear portion of the brush housing 110 by the weight of the brush motor and motor housing 114 10 . Therefore, the cleaning head assembly 108 and the brush housing 110 are specifically designed to ensure that the brush housing 110 is level or at least set for all tilting angles of the handle 116 in the vertical direction during normal use of the vacuum cleaner 100 and on all surfaces. The suction port in the lower plate 22 is maintained in a horizontal plane to maintain optimum performance. 15 Maintaining the suction port in a horizontal plane maximizes the effectiveness of the cleaning head assembly for floor cleaning. The brush casing is no longer subject to external factors that may tilt the brush casing at least on one side and lift the suction port off the floor, such as different carpet piles, the direction of movement of the vacuum cleaner, and the different angles of inclination of the handle to the vertical direction. Maintaining the suction port in a horizontal plane maintains a good suction through the fibers that receive the cleaned carpet 20 and thus maintains the good suction capacity of the cleaning head. The action of the resilient member 38 in conjunction with the operation and movement of the sealing member 40 enhances the performance of the cleaning head. The function of the sealing member 40 is to assist in maintaining a sealed closed air inlet at one of the suction ports 112 by closing a gap between the rear portion of the brush casing and the surface to be cleaned. Maintaining a good seal around the suction port 17 200826892 Maintains good suction through the fibers of the carpet being cleaned and thus maintains good suction capacity. The invention is not limited to the precise details of the above embodiments. Modifications that do not affect the nature of the invention are intended to be included within the scope of the invention. For example, the tension spring 5 yellow can be replaced with any elastic member, and the seal around the joint 28 can be constructed of any airtight material. The flashing sheet for sealing may be constructed of any suitable material, such as plastic or rubber, and may be attached to the casing by any suitable means, such as the use of adhesives, fasteners, or other fasteners. The sealing flashing piece can be movably attached to the casing by any suitable means such as pivoting, sliding engagement or other fixing means. Moreover, those skilled in the art will appreciate that the number, arrangement and shape of the carpet sheets on the underside of the brush housing may vary. Those skilled in the art will come up with other modifications and changes.
