Description

TECHNICAL FIELD

[0001] Embodiments of the present invention relate to a cleaner head. More particularly, embodiments of the present invention relate to a cleaner head detachably provided to a hose portion of a vacuum cleaner. BACKGROUND

[0002] Dust or foreign matter can remain on a surface such as a floor, a carpet, a shelf, etc. for a long time. In this case, the dust or foreign matter is firmly adhered to the surface in a state of high surface energy such as static electricity, and thus it is difficult to remove the firmly adhered dust or foreign matter only by the vacuum force of the vacuum cleaner itself.

[0003] To solve this problem, the brush portion can be further included around the suction port of the vacuum cleaner. Here, the user can directly operate the brush portion to separate the firmly adhered dust or foreign matter from the surface, and then use the vacuum force to suck the separated foreign matter or dust from the surface.

[0004] In addition, to more effectively separate and suck the foreign matter or dust from the surface, the head portion included in the vacuum cleaner can include a vibration member.

[0005] However, when the brush portion vibrates, the vibration is transmitted to the housing portion covering the brush portion and the handle portion connected to the housing portion. Thus, the user who holds the handle portion can feel fatigue due to the vibration, and thus vibration syndrome can occur. Also, the vibration is not only transmitted to the brush portion but also to the housing portion covering the brush portion, and thus loss of the vibration can occur.

[0006] In addition, an additional power source is required to induce the vibration of the brush included in the cleaner head. In this case, the vibration generating portion for inducing the vibration of the brush included in the cleaner head should be electrically connected to the cleaner body. For this reason, a connection structure for electrically connecting the cleaner head and the cleaner body is also required, and thus there is a problem in that the structure of the wireless cleaner is complicated and the weight is increased. SUMMARY

[0007] TECHNICAL PROBLEM

[0008] Therefore, embodiments of the present invention provide a cleaner head in which the vibration can be selectively transmitted to the brush portion.

[0009] Also, embodiments of the present invention provide a cleaner head in which the brush portion can be supplied with power by its own power source.

[0010] TECHNICAL SOLUTION

[0011] The dust collector head of the embodiment of the present application includes a housing part formed with an opening such that a lower part is open, a vibration generating part provided to cover the opening, having at least one suction port through which suction force passes and being capable of generating a vibration force, a brush part disposed at a lower part of the vibration generating part, obtaining the vibration force transmitted to vibrate, and a vibration isolation part disposed along a periphery of the housing part, isolating the vibration of the housing part and the vibration generating part.

[0012] In one embodiment of the present application, the vibration isolation part can be interposed between the housing part and the vibration generating part.

[0013] In one embodiment of the present application, the vibration isolation part can have a shape of a closed curve on a lower surface plane of the housing part.

[0014] In one embodiment of the present application, the vibration isolation part can include a rubber material or a polymer resin material.

[0015] In one embodiment of the present application, the vibration isolation part can have a "U" letter vertical sectional shape.

[0016] In one embodiment of the present application, the vibration generating part can include a vibration plate covering the opening and formed with the suction port, a vibration hammer disposed at an upper part of the vibration plate, and a motor coupled to the vibration hammer at an upper part of the vibration plate to supply a driving force to the vibration hammer.

[0017] The vibration plate can have a pair of suction ports having different widths.

[0018] In one embodiment of the present application, a first locking member to fix the vibration isolation part to a lower surface of the housing part can be further included.

[0019] The first locking member can include a hook.

[0020] In one embodiment of the present application, a handle part provided to be capable of being coupled with an upper end part of the housing part and including a flow channel formed in an inside can be further included.

[0021] The handle part can further include a battery provided in an inside of the handle part and supplying power to the vibration generating part, and a controller to control the power supply of the vibration generating part by the battery.

[0022] The handle part can further include a sensor to sense a pressure in the inside of the flow channel and supply a pressure signal to the controller.

[0023] In addition, the handle part can further include a second coupling part having one end part provided to be capable of being coupled with an extension tube.

[0024] Also, the housing portion can further include a housing body in which the opening is formed, and a connecting member connecting the housing body and the handle portion to each other.

[0025] The connecting member can be coupled to be rotatable in a direction inclined with respect to an extension direction of the housing body.

[0026] Technical Effects

[0027] According to the embodiment of the present application, the vibration isolation portion can suppress the transmission of the vibration generated from the vibration generation portion to the handle portion by suppressing the transmission of the vibration generated from the vibration generation portion to the housing portion. Also, the vibration isolation portion can selectively transmit the vibration from the vibration generation portion to the brush portion, so that the vibration can be effectively transmitted to the brush portion.

[0028] In addition, since the inside of the housing portion includes a battery, the vibration generation portion can be supplied with power by itself. Thus, the cleaner head can generate the vibration using the power of itself by omitting the power source for driving the vibration generation portion. BRIEF DESCRIPTION OF DRAWINGS

[0046] Referring to Figures 1 to 3 , the cleaner head 100 of the embodiment of the present application includes a housing portion 110, a vibration generation portion 150, and a brush portion 160 (see Figure 4) and a vibration isolation portion 130. The cleaner head 100 can be detachably mounted to a hose 210 (see Figure 4 ) of a cleaner body (not shown).

[0047] The housing portion 110 is formed with an opening such that a lower portion is open. An inside of the housing portion 110 is formed with a first flow passage through which a vacuum force can be transmitted. The first flow passage is provided to communicate with the opening. The housing portion 110 is provided to be capable of covering the vibration generating portion 150.

[0048] The housing portion 110 can have a bar shape. The housing portion 110 can be composed of a high molecular resin material such as PET.

[0049] The vibration generating portion 150 is configured to cover the opening of the housing portion 110. The vibration generating portion 150 can have a shape corresponding to a shape of the opening. For example, in a case where the opening has an elliptical shape, the vibration generating portion 150 can have an elliptical shape on a plane.

[0050] The vibration generating portion 150 generates a vibration force. The vibration generating portion 150 can include at least one suction port 151a, 151b. The suction ports 151a, 151b can function as flow passages through which the vacuum force can pass in communication with the first flow passage. The vibration generating portion 150 is provided to be capable of transmitting the vibration force to the brush portion 160. In particular, the vibration force generated by the vibration generating portion 150 can not be transmitted to the housing portion 110 due to the vibration isolation portion 130, and can be selectively transmitted to the brush portion 160.

[0051] The brush portion (160; see Figure 4 ) is disposed at a lower portion of the vibration generating portion 150. The brush portion 160 can obtain the vibration force from the vibration generating portion 150 to vibrate. Thus, as the brush portion 160 vibrates, dust or foreign matter firmly stuck to a surface can be easily removed.

[0052] The vibration isolation portion 130 is disposed along a periphery of the housing portion 110. Also, the vibration isolation portion 130 can be disposed along an outline of the opening of the housing portion 110. The vibration isolation portion 130 can isolate vibration from the vibration generating portion 150 to the housing portion 110. Thus, the vibration isolation portion 130 can inhibit transmission of vibration generated by the vibration generating portion 150 to the housing portion 110. Thus, the vibration isolation portion 130 can enable the vibration force generated by the vibration generating portion 150 to be selectively transmitted to the brush portion 160 by preventing the vibration force from being transmitted to the housing portion 110.

[0053] The vibration isolation portion 130 can be interposed between the housing portion 110 and the vibration generating portion 150. For example, the vibration isolation portion 130 can be arranged along a critical point between the housing portion 110 and the vibration generating portion 150. Accordingly, the vibration isolation portion 130 can isolate the entire housing portion 110 with respect to the vibration of the vibration generating portion 150.

[0054] The vibration isolation portion 130 can have a shape of a closed curve on a plane along the lower surface of the housing portion 110. Also, in the case where the opening is an elliptical shape, the vibration isolation portion 130 can have a shape of an ellipse on a plane.

[0055] The vibration isolation portion 130 can be composed of an elastic material such as a rubber material or a high polymer resin material. The vibration isolation portion 130 can thus effectively isolate the housing portion 110 with respect to the vibration generated by the vibration generating portion 150.

[0056] The vibration isolation portion 130 can have a "U" shaped vertical cross-sectional shape. The vibration isolation portion 130 can thus cushion the vibration force, and thus can elastically recover its shape. The vibration isolation portion 130 can effectively isolate the vibration generated by the vibration generating portion 150.

[0057] In one embodiment of the present application, the vibration generating portion 150 can include a vibration plate 151, a vibration hammer 153, and a motor 155.

[0058] The vibration plate 151 covers the opening. In the case where the opening is an elliptical shape, the vibration plate 151 can also have an elliptical shape. The vibration plate 151 is disposed so as to support the vibration hammer 153 and the motor 155. As the vibration plate 151 vibrates, the brush portion 160 attached to the vibration plate 151 can also vibrate.

[0059] In addition, the suction inlets 151a, 151b can be formed in the vibration plate 151. The suction inlets 151a, 151b can be communicated to the first flow passage formed in the housing portion 110. The cleaner head 100 can thus suck foreign matter or dust through the suction inlets 151a, 151b by using the suction force transmitted from the first flow passage.

[0060] The vibration hammer 153 is disposed at an upper portion of the vibration plate 151. The vibration hammer 153 can periodically reciprocate in a vertical or horizontal direction.

[0061] The motor 155 is coupled to the vibration hammer 153 at an upper portion of the vibration plate 151. The motor 155 provides a driving force to the vibration hammer 151.

[0062] A connecting rod connecting the motor 155 and the vibration hammer 153 is eccentrically connected, so that the vibration hammer 153 can vibrate when the motor 155 rotates. Thus, as the vibration hammer 153 vibrates, the vibration plate 151 supporting the vibration hammer 153 can also vibrate.

[0063] In addition, the vibration plate 151 can have a pair of suction ports 151a, 151b having different widths. The first suction port 151a is provided at the front end side, and the second suction port 151b is provided at the opposite side. Here, the first suction port 151a can have an elliptical shape, and the second suction port 151b can have a circular shape. The first suction port 151a and the second suction port 151b have different widths, so that air flows having different pressures are formed at the front end side and the opposite side. Thus, the vacuum force transferred from the first flow passage can more effectively suck dust or foreign matter with the air pressure difference.

[0064] In one embodiment of the present application, a locking member 140 for fixing the vibration isolation portion 130 to the lower surface of the housing portion 110 can also be provided. The locking member 140 can include, for example, a hook. The hook is locked in an interference manner between the housing portion 110 and the vibration isolation portion 130, so that the hook can fix the vibration isolation portion 130 to the lower surface of the housing portion 110.

[0065] Alternatively, the vibration isolation portion 130 can also be fixed to the lower surface of the housing portion 110 by an ultrasonic welding process.

[0066] Figure 4 FIG. 6 is a perspective view for explaining a manner in which the handle portion is connected to the hose portion of the dust collector head according to the present application. Figure 1 FIG. 6 is a perspective view for explaining a manner in which the handle portion is connected to the hose portion of the dust collector head according to the present application. Figure 5 FIG. 7 is a block diagram for explaining driving of a battery included in the handle portion of the dust collector head according to the present application. Figure 4 FIG. 7 is a block diagram for explaining driving of a battery included in the handle portion of the dust collector head according to the present application.

[0067] Referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 , the dust collector head 100 can further include a handle portion 170.

[0068] The handle portion 170 is provided to be combined with the upper end portion of the housing portion 110. The inside of the handle portion 170 includes a second flow passage. The second flow passage is communicated with the first flow passage formed in the housing portion 110. Thus, a vacuum generated from a dust collector body (not shown) can be transferred to the first flow passage through the second flow passage. The handle portion 170 can be combined with the upper end portion of the housing portion 110 by a hook combination.

[0069] The housing part 110 can include a housing body 111 formed with the opening and a connecting member 118 connecting the housing body and the handle part.

[0070] The housing body 111 can have a cylindrical shape formed with a hollow inside.

[0071] The connecting member 118 includes a first coupling part 119 configured to detachably couple the housing body 111 to the handle part 170. As an example of the first coupling part 119, a first key having elasticity can be used. The first key can be elastically inserted into or protrude from a hole formed in the handle part 170, so as to couple the connecting member 118 and the handle part 170 to each other.

[0072] In one embodiment of the present application, the handle part 170 can include a battery 171 and a controller 173.

[0073] The battery 171 is provided inside to supply power to the vibration generating part. The vibration generating part 150 included in the cleaner head 100 can be autonomously driven using the battery 171. Thus, an additional unit for supplying power to the vibration generating part 150 can be omitted. As a result, the cleaner head 100 can generate a vibration force using its own power source.

[0074] The controller 173 controls the supply of power from the battery 110 to the vibration generating part.

[0075] For example, the handle part 170 further includes a sensor 175 sensing a pressure inside the second flow passage and providing a pressure signal to the controller 173. The sensor 175 can sense a change in the pressure inside the second flow passage. For example, in a case where a vacuum cleaner body connected to the cleaner head 100 generates a vacuum force, a change in the pressure can occur inside the second flow passage. In this case, the sensor 175 can determine whether a vacuum generating part (not shown) included in the cleaner body is operating by sensing the change in the pressure. The sensor 175 can include, for example, a resonance type pressure sensor or a piezoelectric type pressure sensor.

[0076] The handle part 170 further includes a switch 177. In a case where the sensor 175 senses a change in the pressure, the sensor 175 transmits a sensing signal to the controller 173. In this case, the controller 173 can switch whether to supply power between the battery 171 and the vibration generating part 150 by providing a control signal to control the switch 177.

[0077] In one embodiment of the present application, the handle part 1170 can further include a second coupling part 179 having one end configured to be coupled to the extension tube 210.

[0078] As an example of the second connecting portion 179, a second key having elasticity can be used. The second key elastically extends into or out of the hose 210, so the handle portion 170 and the hose 210 can be coupled to each other.

[0079] In one embodiment of the present application, the connecting member 119 is configured to be rotatable in a direction inclined with respect to the extending direction of the housing body 111, so that the housing body 111 can be bent with respect to the handle portion 170. As described above, since the housing portion 110 is configured to be bent with respect to the handle portion 170, the brush portion 160 connected to the housing portion 110 is easily accessible to a surface having dust or foreign matter, so that the leakage of the vacuum force can be suppressed.

[0080] Industrial Applicability

[0081] As described above, the cleaner head can be mounted to various cleaner bodies. Also, the cleaner head has various shapes, so that cleaning work can be performed using the suction force generated from the cleaner body and the vibration force generated from the cleaner head.

[0082] The above description has been made with reference to preferred embodiments of the present application, but those skilled in the art will appreciate that various modifications and changes can be made to the present application without departing from the scope of the present application as recited in the appended claims and the spirit and scope of the present application.
