In other words, the stick vacuum cleaner and the handy vacuum cleaner share the dust collection unit 206, the electric blower 207, and the storage battery 208.

[0019] The stick handle 102 is provided with a power switch 115, and by pressing this power switch 115, the electric blower 207 and the rotating cleaning body 109 of the suction body 103 are driven.

[0020] A connection hole 102a that penetrates downward is formed at the rear lower part of the stick handle 102. A connection pin 111 that is inserted into the connection hole 102a is provided at the rear upper part of the stick body 101. The connection pin 111 is biased rearward, and by inserting this connection pin 111 into the connection hole 102a of the stick handle 102, the stick handle 102 is fixed to the stick body 101. When removing the stick handle 102 from the stick body 101, the connection pin 111 is pushed in and retracted from the position where it overlaps with the connection hole 102a, and then the stick handle 102 is pulled out (see FIG. 5).

[0021] A suction pipe 202 is provided at the lower part (front part) of the handy body 201. A suction pipe receiver 112 into which the suction pipe 202 is inserted is formed at the lower part of the stick body 101, and by inserting the suction pipe 202 into the suction pipe receiver 112, the movement of the lower part (front part) of the handy body 201 within the open part 110 is restricted. The suction pipe receiver 112 communicates with the suction mouth body 103, and the suction pipe 202 and the suction mouth body 103 communicate with each other.

[0022] In addition, a handy removal button 113 is provided at the front of the upper part of the stick body 101. A handy body receiving part 203 is formed at the upper part (rear part) of the handy body 201. The handy removal button 113 is biased downward by a spring, and the lower end of the handy removal button 113 engages with the handy body receiving part 203, thereby fixing the handy body 201 attached to the opening part 110 to the stick body 101.

[0023] When removing the handy body 201 from the stick body 101, the handy removal button 113 is moved upward against the spring force, and the lower tip of the handy removal button 113 is retracted from the handy body receiving part 203. In this manner, the handy body 201 can be removed from the stick body 101.

[0024] A suction body removal button 114 is provided at the front of the lower part of the stick body 101. A connection hook 107a is provided on the connection tube 107 of the suction body 103. The suction body removal button 114 is biased forward by a spring, and a part of the suction body removal button 114 fits into the connection hook 107a, thereby fixing the suction body 103 to the stick body 101. The suction body 103 is provided with a rotating cleaning body 109 that is rotated by an electric motor (not shown). The rotating cleaning body 109 acts to sweep in dust from the floor surface or the like that is to be cleaned. Note that the rotating cleaning body 109 is not an essential component, and dust may be sucked in only by the suction force of the electric blower 207 without the rotating cleaning body 109. The rotating cleaning body 109 may be rotated by the suction force generated by the electric blower 207, not by the electric motor.

[0025] An upwardly protruding projection 105a is provided at the front of the support portion 105. A projection receiving portion 108 is formed at the rear of the stick body 101, and by inserting this projection receiving portion 108 into the projection 105a, the vacuum cleaner 100 (stick body 101) is supported in an upright position on the charging stand 104.

[0026] Next, we will explain the configuration of the handy body 201. Figures 6 and 7 are external perspective views of the handy body 201 according to an embodiment of the present invention, Figure 8 is a cross-sectional view cut in the front-rear direction of the handy body 201 according to an embodiment of the present invention, and Figure 9 is an external perspective view showing the brush member according to an embodiment of the present invention.

[0027] The handy body 201 functions as a handy vacuum cleaner. The handy body 201 is provided with a handy handle 204 at the upper rear part, a power switch 205 installed in front of the handy handle 204, a dust collecting unit 206 detachably attached to the front part of the handy body 201, and a suction pipe 202 communicating with the dust collecting unit 206.

[0028] Inside the handheld main body 201 are provided an electric blower 207 that generates suction force, a storage battery 208 that supplies power to the electric blower 207 , and a control device 209 that controls the storage battery 208 and the electric blower 207 .

[0029] A brush member 210 is provided in front of the suction pipe 202. The brush member 210 includes a brush 210a that is brought into contact with the surface to be cleaned, a brush support part 210b that serves as a base for attaching the brush 210a, a pair of arms 210c that extend from the brush support part 210b on the side opposite to the brush and are formed so as to sandwich the suction pipe 202 from both sides, and a rotation restricting part 210d that is attached to the brush support part 210b and restricts the rotation of the brush support part 210b.

[0030] The brush member 210 is supported rotatably relative to the suction pipe 202. The pair of arms 210c are provided with a rotating shaft 210c1, and this rotating shaft 210c1 is inserted into a small hole (not shown) formed in the suction pipe 202, and the brush member 210 rotates relative to the suction pipe 202.

[0031] When using brush member 210 as a handheld vacuum cleaner, brush member 210 is rotated so that brush member 210 is positioned on the extension of suction pipe 202. When brush member 210 is rotated, rotation restricting portion 210d comes into contact with the front end of suction pipe 202, restricting the rotation of brush member 210. Brush member 210 is inclined so as to face downward with respect to the forward extension direction of suction pipe 202. When brush member 210 is inclined, the lower side of brush member 210 is open, so the flow path of suction pipe 202 is not blocked.

[0032] When storing brush member 210, brush member 210 is rotated so that brush member 210 faces the rear of suction pipe 202. In other words, brush member 210 rotates so that it can be retracted from an extension of suction pipe 202. When brush member 210 is rotated, arm portion 210c of brush member 210 comes into contact with rotation restricting protrusion 202a formed on the side surface of suction pipe 202, and rotation of brush member 210 is restricted. In this manner, brush member 210 retracts from the front end portion of suction pipe 202.

[0033] With the brush member 210 retracted from the front end of the suction pipe 202, an attachment device 106 such as a gap suction nozzle can be attached to the front end of the suction pipe 202. Other than the gap suction nozzle, for example, an extension tube (not shown) can be connected. The suction pipe 202 is provided with a well-known clamp hook 211, which allows an extension tube to be connected and fixed. Furthermore, the suction nozzle body 103 or another suction nozzle body (second suction nozzle body) can be connected to the front end of the extension tube.

[0034] In other words, when the extension tube and the second suction body are connected to the handheld body 201 of this embodiment, the handheld body 201 can be used as a stick vacuum cleaner (not shown) in the shape of a handheld device held by the user. Also, by supplying power to the tip of the suction pipe 202, an electrically driven motor or an accessory with a built-in LED can be used, and by driving the motor built into the second suction body via the conductive part inside the extension tube, the rotating brush of the second suction body can be driven.

[0035] According to this embodiment, the handy body 201 is provided with a suction pipe 202 to which an extension pipe or the like can be connected, thereby improving the ease of use of the vacuum cleaner.

[0036] When attaching the handy body 201 to the stick body 101, the brush member 210 is retracted from the front end of the suction pipe 202. When attaching the handy body 201 to the stick body 101, first, the suction pipe 202 is inserted into the suction pipe receiving portion 112, and then the handy handle 204 side is pushed into the stick body 101. Then, the lower end of the handy removal button 113 fits into the handy body receiving portion 203, and the handy body 201 is attached to the stick body 101.

[0037] When brush member 210 is retracted from the front end of suction pipe 202, it protrudes rearward (downward) from the surface of suction pipe 202. When attached to stick body 101 in this state, brush member 210 and stick body 101 come into contact. Therefore, in this embodiment, contact between brush member 210 and stick body 101 is avoided as follows.

[0038] As shown in Fig. 5, an opening 116 penetrating the stick body 101 is formed at the rear of the stick body 101. When the handy body 201 is attached to the stick body 101, a part of the brush member 210 protrudes from the opening 116. That is, in this embodiment, when the handy body 201 is attached to the stick body 101, the opening 116 is provided to prevent contact between the brush member 210 and the stick body 101. By configuring in this manner, in this embodiment, the handy body 201 can be smoothly attached to the stick body 101.

[0039] Next, the attachment / detachment structure of the handy main body 201 and the dust collecting unit 206 will be described with reference to Figures 8, 10, and 11. Figure 10 is an external perspective view showing the state in which the dust collecting unit has been removed from the handy main body according to the embodiment of the present invention, and Figure 11 is an external perspective view of the handy main body according to the embodiment of the present invention, viewed obliquely from below. Figure 11 shows the state in which the seal packing has been removed.

[0040] A detachment button 212 for detaching the dust collecting unit 206 from the handy main body 201 is provided at the upper rear of the dust collecting unit 206. The detachment button 212 is biased rearward (toward the handy main body 201) by a spring, and the claw portion 212a of the detachment button 212 enters the handy main body 201 to hold the rear side of the dust collecting unit 206. A hook portion 213 (FIG. 8) is formed at the front of the lower portion of the dust collecting unit 206. A receiver portion 214 for receiving the hook portion 213 is formed above the suction pipe 202. By hooking the hook portion 213 onto the receiver portion 214, the front of the dust collecting unit 206 is held by the handy main body 201, and the rear of the dust collecting unit 206 is held by the handy main body 201 by the detachment button 212.

[0041] Furthermore, an outlet 215 communicating with dust collection section 206 is formed above suction pipe 202. Dust-laden air that flows in from suction pipe 202 is discharged from outlet 215 and flows into dust collection section 206. When used as a stick vacuum cleaner, dust-laden air that has passed through suction body 103, connecting tube 107, and suction pipe 202 is discharged from outlet 215 and flows into dust collection section 206.

[0042] The discharge port 215 is formed shifted to the left or right from the center line C1 of the suction pipe 202. In this embodiment, the discharge port 215 is shifted to the right side as seen from the viewpoint of a user using the vacuum cleaner as a handheld vacuum cleaner. A seal packing 216 is attached to the discharge port 215 to ensure airtightness between the discharge port 215 and the dust collecting part 206. The seal packing 216 has a lip part 216a that maintains airtightness around the opening of the discharge port 215, and a valve body 216b that opens and closes the discharge port 215. The lip part 216a and the valve body 216b are rotatably connected by a rotating part 216c, and the valve body 216b opens and closes the discharge port 215 with the rotating part 216c as an axis.

[0043] When suction force is generated by electric blower 207, valve body 216b rotates from suction pipe 202 toward dust collection section 206. Furthermore, a plurality of ribs 216d protruding from the surface of valve body 216b are formed on the upstream side (suction pipe 202 side) of valve body 216b. The plurality of ribs 216d are formed so as to extend from rotation section 216c toward the counter-rotation section. That is, the plurality of ribs 216d are formed so as to follow the flow of air.

[0044] In this embodiment, since a plurality of ribs 216d are formed on the upstream side of the valve body 216b, the rigidity of the valve body 216b is ensured, and the valve body 216b can be easily opened with the rotating part 216c as a rotating shaft. Furthermore, since the plurality of ribs 216d are arranged along the air flow, the air containing dust that collides with the valve body 216b can be smoothly flowed to the dust collecting part 206 side. Furthermore, when the electric blower 207 is stopped and no suction force is being generated, the weight of the plurality of ribs 216d causes the valve body 216b to operate to close the discharge port 215, so that the spilling of dust from the dust collecting part 206 can be suppressed.

[0045] Next, the configuration of dust collection section 206 will be described with reference to Figs. 12 to 15. The description of Figs. 12 to 15 will be based on the case where the device is used as a stick vacuum cleaner. In this case, the dust collection case 220 side is the lower side, the filter housing section 223 side is the upper side, the attachment / detachment button 212 side is the front side, and the inlet 227 side is the rear side. When the device is used as a handheld vacuum cleaner, the dust collection case 220 side is the front side, the filter housing section 223 side is the rear side, the attachment / detachment button 212 side is the upper side, and the inlet 227 side is the lower side.

[0046] FIG. 12 is an exploded perspective view of a dust collecting unit according to an embodiment of the present invention, FIG. 13 is an external perspective view of the dust collecting unit according to an embodiment of the present invention as seen from the front, FIG. 14 is a cross-sectional view of the dust collecting unit according to an embodiment of the present invention as seen from the left side, and FIG. 15 is a view of the dust collecting unit according to an embodiment of the present invention as seen from the rear.

[0047] The dust collecting section 206 includes a cylindrical dust collecting case 220 with a bottom for collecting dust, an umbrella part 221 mounted in the dust collecting case 220, an inner cylinder 222 connected to the umbrella part 221 and mounted in the dust collecting case 220, a cylindrical filter housing part 223 having the inner cylinder 222 at the bottom and housing a filter, a first dust trapping filter 224 housed in the filter housing part 223, and a second dust trapping filter 225 housed in the filter housing part 223 and arranged downstream of the first dust trapping filter 224. The first dust trapping filter 224 is made of sponge and can be washed with water. The second dust trapping filter 225 is folded in a pleated shape (pleats) to expand the ventilation area, and is bonded to a circular frame body 225a. In this embodiment, two dust trapping filters, the first dust trapping filter 224 and the second dust trapping filter 225, are provided, but the number of dust trapping filters may be one.

[0048] An upper portion (downstream side) of the second dust filter 225 faces the suction port of the electric blower 207. A cleaning brush 226 for cleaning the second dust filter 225 is removably attached to the outer periphery of the dust collection case 220. The cleaning brush 226 is provided with bristles 226a, and the bristles 226a are used to clean dust adhering to the second dust filter 225, for example.

[0049] The filter housing section 223 includes a partition wall 223a that supports the first dust filter 224, and an opening 223b formed in the center of the partition wall 223a. An inner cylinder 222 having a plurality of support posts 222a is fixed around the opening 223b. A breathable mesh filter 222b is provided between adjacent support posts 222a of the inner cylinder 222. The inner cylinder 222 also includes a circular inner cylinder frame 222c that connects the plurality of support posts 222a. A rail projection 222d having a plurality of cutout portions 222d1 that protrude toward the outer periphery and are cut out is provided on the outer periphery of the inner cylinder frame 222c.

[0050] A circular annular wall 221a is formed on the upper side (the inner tube 222 side) of the umbrella part 221, and a plurality of protrusions 221b protruding inward are formed on the inner circumference of the annular wall 221a. When connecting the umbrella part 221 and the inner tube 222, the plurality of protrusions 221b on the umbrella part 221 side are aligned with the positions of the plurality of notches 222d1 on the inner tube 222 side, and the plurality of protrusions 221b are inserted into the plurality of notches 222d1. Then, the umbrella part 221 is rotated to the right or left. The plurality of protrusions 221b are positioned above (the inner tube 222 side) the position of the rail protrusion 222d, and the umbrella part 221 and the inner tube 222 are connected. When removing the umbrella portion 221 from the inner cylinder 222, the umbrella portion 221 is rotated to the right or left to align the multiple protrusions 221b with the multiple cutout portions 222d1, and then the umbrella portion 221 is pulled out.

[0051] The umbrella part 221 is formed with a cross-shaped bridge part 221c arranged so as to cross the inside of the umbrella part 221, and further includes a cross-shaped cross rib 221d extending from the bridge part 221c toward the bottom of the dust collection case 220. The tip of the cross rib 221d is formed in a straight line so as to follow the bottom side of the dust collection case 220, and both ends of the straight line are formed in an arc shape. As described later, the cross rib 221d causes dust swirling in the dust collection case 220 to collide with the cross rib 221d, and the dust is compressed by the force of the collision. In addition, a mesh filter 221e is provided between the adjacent cross-shaped bridge parts 221c. In addition, an annular protrusion part 221f protruding toward the dust collection case 220 is formed on the outer periphery of the umbrella part 221. The shape of the protrusion part 221f is the same as the inner periphery shape of the dust collection case 220. Moreover, the protrusion 221f is located lower than the inlet 227, and further lower than the halfway position of the dust-collection case 220 in the up-down direction.

[0052] The filter housing part 223 and the dust collection case 220 are configured to be detachable. A plurality of protrusions 223c protruding toward the outer periphery are formed on the outer periphery of the filter housing part 223. Meanwhile, a plurality of upper protrusions 220a and lower protrusions 220b protruding toward the inner periphery are formed on the inner periphery of the dust collection case 220. The upper protrusions 220a have a plurality of cutout portions 220c that are partially cut out, and are formed to have a shorter circumferential length than the lower protrusions 220b. The upper protrusions 220a and the lower protrusions 220b are formed to partially overlap on the open side of the dust collection case 220.

[0053] When connecting the filter housing portion 223 and the dust collection case 220, the multiple notches 220c on the dust collection case 220 side are aligned with the positions of the multiple protrusions 223c on the filter housing portion 223 side, and the multiple protrusions 223c are inserted into the multiple notches 220c. Then, the dust collection case 220 is rotated to the right or left. The multiple protrusions 223c are inserted between the upper protrusion 220a and the lower protrusion 220b, and the filter housing portion 223 and the dust collection case 220 are connected. When removing the dust collection case 220 from the filter housing portion 223, the dust collection case 220 is rotated to the right or left, the multiple protrusions 223c are aligned with the positions of the multiple notches 220c, and the dust collection case 220 is pulled out.

[0054] The dust collection case 220 is formed with an inlet 227 through which dust-laden air flows in. The inlet 227 communicates with the outlet 215 of the suction pipe 202 via a seal packing 216. The inlet 227 is disposed at a position shifted from the center line C2 of the dust collection section 206 (FIG. 15). In this embodiment, the inlet 227 is disposed shifted to the right when viewed from the viewpoint of a user using the vacuum cleaner as a stick vacuum cleaner or a handheld vacuum cleaner.

[0055] When the user presses the power switch 115 or the power switch 205 in a state in which the vacuum cleaner is used as a stick vacuum cleaner or a handheld vacuum cleaner, the electric blower 207 is driven to generate suction force. The air containing dust passes from the suction port body 103 to the suction pipe 202 or the suction pipe, and is discharged from the discharge port 215 to the dust collection section 206 side. The air containing dust discharged from the discharge port 215 passes through the inlet 227 and flows into the dust collection case 220. Since the inlet 227 is disposed at a position shifted from the center line C2 of the dust collection section 206, the air containing dust that flows in from the inlet 227 flows along the inner surface of the dust collection case 220 and becomes a swirling flow at the position of the inner cylinder 222 (broken line in FIG. 14). Some of the air from which the dust has been removed passes through mesh filter 222 b of inner cylinder 222 , and then passes through first dust filter 224 and second dust filter 225 where fine dust is removed, and is then sucked into electric blower 207 .

[0056] The dust flowing as a swirling flow collides with the inner wall of the dust collection case 220 by centrifugal action, passes through the gap between the protrusion 221f and the dust collection case 220, and moves to the bottom of the dust collection case 220. The dust that has moved to the bottom of the dust collection case 220 collides with the cross rib 221d, whereby the swirling flow is suppressed, and the dust is compressed by suction force. The air from which the dust has been separated passes through the mesh filter 221e arranged between the bridge parts 221c, and this mesh filter 221e captures light-weight dust such as cotton dust and fine dust. The dust filtered by the mesh filter 221e is compressed by suction force. The air that has passed through the mesh filter 221e is further passed through the first dust trapping filter 224 and the second dust trapping filter 225 to remove fine dust, and is sucked into the electric blower 207.

[0057] In this embodiment, the shape of the protrusion 221f is the same as the inner peripheral shape of the dust collection case 220. Therefore, the gap between the protrusion 221f and the dust collection case 220 becomes uniform, the loss of the swirling flow is suppressed, and the dust separation action can be improved. In addition, the protrusion 221f is located below the inlet 227 (the bottom side of the dust collection case 220) and further below the half position in the vertical direction of the dust collection case 220, so that the dust that has passed through the gap between the protrusion 221f and the dust collection case 220 can be prevented from flowing back through the gap and flying up to the inner cylinder 222 side.

[0058] Next, the storage battery 208 will be described. Fig. 16 is an external perspective view of the storage battery unit according to the embodiment of the present invention, and Fig. 17 is a top view of the storage battery unit according to the embodiment of the present invention.

[0063] When electric blower 207 starts operating, the exhaust air flows into exhaust passage 238 and further flows into first opening 236 disposed downstream of exhaust passage 238. The exhaust air that flows into first opening 236 flows along the outer peripheral surface of storage battery 208 and is discharged from second opening 237.

[0064] According to this embodiment, the storage battery unit 230 is provided with the first opening 236 and the second opening 237, and the exhaust air of the electric blower 207 is allowed to flow therethrough, so that the temperature rise of the storage battery 208 can be suppressed.

[0065] Charging of the storage battery 208 is performed while the stick vacuum cleaner is placed on the charging stand 104 as shown in FIGS.

[0066] In this embodiment, the control board 233 is equipped with a function for controlling the main body and the battery, but the board for controlling the main body may be provided as a separate component external to the storage battery unit 230 and mounted on the handheld main body 201, etc.
