[0021] The dust collecting box 2 is a cyclone type and has a function of separating the dust of the air containing the dust sucked in from the introduction pipe 14 from the air and collecting the dust. The dust collecting box 2 is arranged at the front of the motor housing portion 11 with the axial direction as the front-rear direction, and has a substantially cylindrical outer tube 2a. In addition, a substantially rectangular inflow port 2 b connected to the introduction pipe 14 is formed on the upper surface (side surface) of the dust box 2. The dust-containing air that has flowed into the inflow port 2b is separated from the air in the dust collecting box 2, and the air separated from the dust is discharged from the rear (back) of the dust collecting box 2. (35) FIG. 35 is an external view of the dust box 2. (a) is a front view when the upper side (refer to FIG. 2) is front, and (b) is a right side view when the upper side is front. Fig. 36 is a cross-sectional view taken along line II and JJ shown in Fig. 35, (a) is a cross-sectional view taken along line II shown in Fig. 35 (a), and (b) is shown in Fig. 35 (b). Shown is the JJ line cross section. The dust collecting box 2 is composed of an outer tube 2a and an inner tube 200 described later. The outer cylinder 2a has a substantially cylindrical shape, and has a generally rectangular inflow port 2b on the upper surface (side of the cylinder) as described above, and has front and rear openings. In addition, as shown in FIG. 36 (a), it is divided into a separation portion 2a1 which is a rear portion that swirls and separates air containing dust sucked by the inflow port 2b, and a front portion which is a storage portion 2a2 that contains the separated dust. [0022] The inner cylinder 200 has a substantially cylindrical shape as shown in FIG. 36, and has a cylinder portion 210 provided with a mesh portion 220 at the upper (rear) and a omitted structure at the lower (front). At the time of the cover 2c, the dust piston portion 240 is pushed out. The piston portion 240 is an umbrella portion 230 included in a lower portion (front) of the cylindrical portion 210, and an annular rib (250a, 250b, 250c) is provided on the umbrella portion 230. The ring-shaped ribs are provided so that the dust carried to the receiving portion 2a2 does not easily return to the separation portion 2a1 side. In this embodiment, the ring-shaped ribs 250a and 250b are provided at the umbrella portion 230 and the ring-shaped rib The 250c is provided on the piston portion 240, but its diameter, position, and number are not limited thereto. Among the plurality of annular ribs, the annular rib 250a can change the ratio of the swirling flow of the separation portion 2a1 to the flow conveyed toward the receiving portion 2a2, which also effectively prevents dust from returning to the separation portion 2a1 side. In order to obtain such an effect, the annular rib 250a is provided immediately adjacent to the substantially rectangular inflow port 2b provided in the outer cylinder 2a. The inflowing air (including dust) is bounded by the annular ribs 250a, and the upper side can strengthen a part of the flow swirling around the separation portion 2a1, and the lower side becomes a flow conveyed directly toward the containing portion 2a2. When there is no ring-shaped rib 250a, the flow system swirling in the separation portion 2a1 faces the accommodation portion 2a2 while turning, and passes from the accommodation portion 2a2 to the separation portion 2a1 while passing through the piston portion 240. At this time, although the return of dust is suppressed by the annular ribs 250b and 250c, the dust may return to the separation portion 2a1. By providing the annular ribs 250 a like the present embodiment, the swirling flow swirling in the separation portion 2 a 1 can be strengthened, and the returning dust can be prevented from adhering to the mesh portion 220 of the inner tube 200. [0023] In this embodiment, although the annular rib 250a is provided at a position slightly close to the inflow port 2b, it is not limited to this, and may be provided at a position where the inflow port 2b is bisected. In addition, although the ring-shaped rib 250 a is provided on the umbrella portion 230, it may be provided on the cylindrical portion 210 including the mesh portion 220 instead of the umbrella portion 230. [0024] In addition, the cover 2c, which is opened and closed when the dust accumulated in the dust box 2 is discarded in front of the dust box 2, is rotatably supported through the hinge portion 2d. In addition, a lid lock mechanism 2e including a release button 2f for releasing the lock of the lid 2c is provided on an upper portion of the lid 2c. [0025] A filter 5 is housed in the dust collecting box 2 at the rear end in the axial direction of the outer tube 2a. The screen 5 is configured to be folded into a folded shape, which can increase the screen area and reduce the pressure loss caused by the screen 5. In addition, by pressing the button 5a provided on the upper part of the dust collecting box 2, the filter 5 can be removed, and on the side opposite to the button 5a (the side below the arrow in the figure), there is provided a mechanism for collecting dust from the cleaner body 1. Button 5b for box 2 removal.滤 In addition, the filter 5 is configured by, for example, a high-density HEPA filter (High Efficiency Particulate Air Filter). The so-called HEPA filter refers to having a rated air volume for a particle size of 0. 3μm particles have 99. Particle capture rate above 97%, An air filter with an initial pressure loss of 245 Pa or less.  Alas, For the mechanism inside the dust box 2, It can be configured according to Japanese Patent Application Laid-Open No. 2016-137165.  [0026] Figure 3, This is a perspective view of the electric vacuum cleaner in a state where the lid lock mechanism 2e is operated to open the lid 2c. Figure 4 is a longitudinal sectional view of an electric vacuum cleaner, Figure 5 is a side view.  As shown in Figures 3 to 5, Electric vacuum cleaner 100, The dust collection box 2 is mounted below the main body portion 10 and in front of the motor housing portion 11. at this time, If the dust box 2 is installed in the cleaner body 1, The lid lock mechanism 2e is provided on the upper side (the side substantially opposite to the main body portion 10) shown by an arrow in the figure. In addition, a hinge portion 2d is provided on the lower side (the side not facing the main body portion 10). In addition, The release button 2f provided in the lid lock mechanism 2e is located further inward than the side surface of the body portion 10 located immediately from the left side of the cleaner body 1 (the body portion 10). In other words, it is provided at a position which does not protrude further than the side surface of the main body portion 10. This is because when the release button 2f is provided at a position protruding more than the side surface of the main body portion 10, There is a possibility that the cover 2c will be removed during cleaning, However, by preventing the release button 2f from protruding from the side of the main body portion 10, Can prevent the release of the cover 2c, And can prevent malfunction. E.g, During cleaning, The cleaner body 1 may come into contact with furniture or the like. at this time, Since the release button 2f is provided farther than the side of the main body portion 10, Therefore, the risk of accidental contact of the release button 2f with the furniture can be reduced, Or the cover 2c may be accidentally opened. The position of the release button 2f provided in the lid lock mechanism 2e is not limited to this, It may be installed in a position close to the right side of the cleaner body 1. Like the present invention, In order to be able to press the release button 2f from the side of the body portion 10, Thereby, the dust in the dust collecting box 2 can be easily discharged in a single operation at a garbage disposal place such as a garbage can. In addition, The dust collecting box 2 is installed in the cleaner body 1, And the opening of the dust box 2 in a state where the cover 2c is opened by the cover locking mechanism 2e, The opening is connected in the same direction as the connection opening 10 a as the opening of the cleaner body 1. With this, Can discharge dust from dust box 2 In addition, it is possible to discharge dust that may remain in the introduction pipe 14.  And, The dust box removing button 5b shown in the foregoing FIG. 4 and FIG. 5, By sliding in the forward direction shown by the arrows on the way, The dust box 2 can be removed from the cleaner body 1. therefore, Even when the cleaner body 1 is standing on the charging stand 70 (during charging), only the dust box 2 can be transported and trash can be discarded. In addition, By only removing the dust box 2 from the cleaner body 1, Can be easily washed in the case of the dust box 2 being dirty, etc. Therefore, the dust box 2 can be kept clean. According to the above invention, Since it can correspond to the state where the dust box 2 is installed in the cleaner body 1, The status of the disassembly and the condition of the user Therefore, it is possible to provide an electric vacuum cleaner with good usability.  [0027] In addition, In the dust box 2, The maintenance brush is provided in a freely removable manner for 2s. The maintenance brush for 2s, It is arranged at a position that is hard to see from the outside when the dust box 2 is installed in the cleaner body 1. therefore, Not easy to fall off during operation, In addition, It is not necessary to store the maintenance brush 2s in a place different from the electric vacuum cleaner 100.  [0028] As shown in Figure 4, To the motor case portion 11 of the body portion 10, An electric blower 40 is housed. In the motor case portion 11, Under the electric blower 40, A body substrate 50 (control substrate) that controls the cleaner body 1 is housed.  [0029] Electric blower 40, The rotary drive shaft 40a is placed horizontally so that it faces the front-rear direction. In addition, The air exhausted from the electric blower 40, The main substrate 50 disposed under the electric blower 40 flows, Then, the main body substrate 50 is cooled.  [0030] The main body substrate 50, It is divided into two sections, Install parts mainly on the opposite side. The air exhausted from the electric blower 40, The flow is performed in such a manner that the parts (heat generating parts) of the body substrates 50 that are opposed to each other are cooled.  [0031] In addition, Electric blower 40 and main body substrate 50, It is arranged so as to overlap in the vertical direction. therefore, The size in the front-back direction can be made shorter. In addition, Electric blower 40 and main body substrate 50, It is located below the first holding portion 12a1 of the handle portion 12. With this, When the user grasps the grip portion 12a and operates, The center of gravity of the electric vacuum cleaner 100 will be located near the lower part of the first holding portion 12a1, Therefore, when the front end of the electric vacuum cleaner 100 is used upwards, The electric vacuum cleaner 100 can be stably held.  [0032] In addition, Between the first holding portion 12a1 and the upper surface 11c of the motor housing portion 11, A gap 12c of a width dimension H1 for inserting a hand is formed. In addition, Between the second holding portion 12a2 and the back surface 11d of the motor case portion 11, A gap 12d having a width dimension H2 wider than the width dimension H1 is formed. in this way, When the first holding portion 12a1 is held for cleaning, To be able to keep it in the extended state, Therefore, it is not necessary to hold the first holding portion 12a1 firmly. Then, the electric vacuum cleaner 100 can be moved back and forth. In addition, When the second gripping portion 12a2 is gripped and cleaned, It is necessary to insert the hand (finger) deeply into the gap 12d and hold it tightly. Therefore, the width dimension H2 is wider than the width dimension H1. This makes it possible to stably hold the second holding portion 12a2.  [0033] In addition, The thickness T1 of the first holding portion 12a1 is formed to be thin, The thickness T2 of the second gripping portion 12a2 is formed to be thicker than the thickness T1. that is, The first holding portion 12a1 is thinner, The second holding portion 12a2 has a relatively large dimension. in this way, When the second grip portion 12a2 is grasped and cleaned, By making the thickness T2 of the second holding portion 12a2 thicker, Can be easily and surely held, In addition, the strength of the second grip portion 12a2 can be increased.  [0034] Battery 3, For example, it can be configured with a lithium ion battery having high energy efficiency. In addition, Battery 3, It is arranged below the second gripping portion 12a2 of the handle portion 12. in this way, By arranging the battery 3 at the rear end of the electric vacuum cleaner 100, The center of gravity of the handle portion 12 can be brought close to the second holding portion 12a2, Therefore, when the front end of the electric vacuum cleaner 100 is used upwards, Can make operation feel light.  003 [0035] Battery lock member 13, A claw portion 13 a that is locked to the battery 3 is formed on the free end side. In addition, Battery lock member 13, It is arranged so as to surround the back surface of the battery 3 from the upper end to the lower end. And it is comprised so that the claw part 13a may be locked with the lower surface of the battery 3 on the lower surface of the rear end of the battery 3.   in this way, By making the battery 3 a removable type, Compared with those whose batteries are not removable, Replacement of the battery 3 becomes easy. In addition, With optional prepared battery 3, And a charging case capable of charging the prepared storage battery 3, When the battery on the body side of the electric vacuum cleaner 100 is consumed, Can be immediately replaced with a spare battery 3, This can extend the cleaning time. By doing so, E.g, This is effective when cleaning a spacious floor such as a shop.  [0036] FIG. 5 The exhaust port of the electric vacuum cleaner is in the first state, (a) a side view, (b) is a sectional view taken along the line A-A of (a).  As shown in Figure 5 (a), Electric vacuum cleaner 100, It has an exhaust port 16 for discharging the sucked air to the outside.

In addition, In the fitting recess 17a, A fitting protrusion 17c is formed to fit into the recessed portion 73d (see FIG. 13) of the charging station 70.  [0063] FIG. 15 It is an exploded perspective view showing a charging stand of the electric vacuum cleaner.  As shown in Figure 15, Extension member 80, The user is charged when the electric vacuum cleaner 100 (see FIG. 1 (a)) is charged in an upright state. And is structured to have tubes 81, Relay terminal 82, Second charging terminal 83.  [0064] Tube 81, From a design perspective, For example, it is made of light weight such as aluminum alloy, The relay terminal 82 is held halfway in the axial direction. In addition, Tube 81, The second charging terminal 83 is held at the upper end in the axial direction. By making the tube 81 metal, Can make the charging station 70 appear slim in appearance, Further, a large mold is not required when manufacturing the extension member 80. also, Tube 81, Is not limited to metal, It may be made of synthetic resin.  [0065] In addition, Tube 81, The connection portion 81s protruding from the relay terminal 82 toward the lower side, It is connected to a connection holding portion 72 c integrally formed in the vertical portion 72. Link holding section 72c, It is formed into an elongated cylindrical shape in the axial direction, An insertion hole 72c1 into which the connection portion 81s of the tube 81 is inserted is formed in the upper surface 72a.

This terminal section, Although not shown, However, it has the same structure as the main body terminal part 17 shown in FIG.  [0068] Holding member 82b, Has a flange 82b1 extending toward the connection terminal portion 82a A cylindrical body 82b2 which is formed into a truncated cone shape in a side view from the flange 82b1 and is fixed upward from the flange 82b1.  [0069] So, Relay terminal 82, When the tube 81 is inserted into the connection holding portion 72c and installed, The connection terminal portion 82a is connected to the first charging terminal 73 and is electrically connected.  [0070] The extension tube holding portion 82c, Is formed in front of the connecting terminal portion 82a, It also has a pair of holding pieces 82c1 that hold the extension tube 300 (see FIG. 1 (a)) from the left and right sides and hold 82c1. A pair of holding pieces 82c1, 82c1, The system is configured to be able to flex and deform, Press the extension tube 300 (refer to FIG. 1 (a)) through the gap 82c2, This allows the extension tube 300 to be held on the holding pieces 82c1. 82c1.  [0071] Extension hose holding portion 82d, For users who store the extension hose 800 (refer to Figure 25), And has front retaining pieces 82d1, Lower holding piece 82d2.  [0072] Front holding sheet 82d1, A plate-shaped person sandwiched and held by the tube 81 side, It is formed so that it may protrude upward on the upper surface of the connection terminal part 82a. In addition, The front end (upper end) of the front holding piece 82d1, The system is formed to be curved toward the tube 81 side.  [0073] The lower holding piece 82d2, The lower one supporting the extension hose 800, And it has a lower support part formed across the connection terminal part 82a to the cylindrical body 82b2. In addition, Lower holding piece 82d2, The connecting terminal portion 82a and the holding member 82b, The strength of the relay terminal 82 is improved.  [0074] The second charging terminal 83, Has the same structure as the first charging terminal 73, The electric vacuum cleaner 100 (see FIG. 1 (a)) in an upright state can be charged in a standing state. In addition, Second charging terminal 83, It has a holding portion 83a held at the upper end of the tube 81. On the upper surface 83a1 of the holding portion 83a, The second charging terminal 83 is formed upward.  [0075] In addition, In front of the holding portion 83a, The peripheral surface of the dust box 2 receiving the electric vacuum cleaner 100 is formed, And the suppression part 83b of the shake of the electric vacuum cleaner 100 is suppressed. The front face of the suppression section 83b, The system is formed so as to bend forward while expanding toward the left and right.  [0076] FIG. 16 It is a side view showing a charging stand of the electric vacuum cleaner.  As shown in Figure 16, Charging station 70, In a state where the connection terminal portion 82a of the relay terminal 82 is directed to the front side, The tube 81 is inserted into the connection holding portion 72c from above. and, When the connection portion 81s (see FIG. 15) of the tube 81 lower than the relay terminal 82 is inserted into the connection holding portion 72c, Then, the first charging terminal 73 (refer to FIG. 15) is fitted to the relay terminal 82. The first charging terminal 73 is electrically connected to the relay terminal 82. In addition, Relay terminal 82, It is electrically connected through a wire (not shown) in the second charging terminal 83 and the tube 81.  [0077] At this time, In the side view of Figure 16, The position of the back (rear) of the connection holding portion 72c, The position of the extension member 80 is substantially the same as that of the back surface (rear surface). In addition, Extension 71e, It is comprised in the side view of FIG. 16, It protrudes rearward than the connection holding part 72c and the extension member 80.  [0078] In addition, The upper surface 83a1 of the holding portion 83a, Tilt it slightly downward. In addition, Second charging terminal 83, It is arranged obliquely along the slope of the upper surface 83a1.  [0079] Figure 17, It is a side view when the electric vacuum cleaner is installed in an upright state on a charging station. also, Direction arrow in Figure 17, Shows the orientation of the charging station 70 (the same applies to FIG. 18).  As shown in Figure 17, The electric vacuum cleaner 100 is in an upright state, It is connected to the second charging terminal 83 for charging. at this time, The user is holding the handle portion 12 with the extension tube 300 facing down, And the cleaner body 1 is lowered from above the second charging terminal 83, Thereby, the body terminal portion 17 is connected to the second charging terminal 83. at this time, Since the second charging terminal 83 is formed upward, Therefore, by the weight of the electric vacuum cleaner 100, The body terminal portion 17 can be reliably connected to the second charging terminal 83.  [0080] In addition, The dust collection box 2 is connected to the suppression section 83b. The extension tube 300 is held by the extension tube holding portion 82 c of the extension member 80. In addition, Part of the standard suction port 400, It is in contact with the mounting surface 71 a of the base 71. With this, Even when charging is performed in a state where the center of gravity of the electric vacuum cleaner 100 is high, The electric vacuum cleaner 100 can also be stably held on the charging stand 70.  [0081] In addition, When the electric vacuum cleaner 100 in the upright state is charged by the charging station 70, The electric vacuum cleaner 100 is designed for vertical direction (up and down direction), The posture of leaning forward is held only at the angle α. in this way, The electric vacuum cleaner 100 is held in a forward tilted position, By this, the center of gravity of the electric vacuum cleaner 100, Will be more forward than when the electric vacuum cleaner 100 is held upright, Therefore, the electric cleaner 100 can be prevented from falling backward.  [0082] Again, Charging station 70, When not connected to the power cord 76, When the battery 3 is not charged, It can also be used as a stand for storing the electric vacuum cleaner 100.  [0083] FIG. 18, It is a side view when the electric vacuum cleaner is installed on the charging station in a handheld state.  As shown in Figure 18, The electric vacuum cleaner 100 is in a handheld state, It is connected to the first charging terminal 73. that is, The state in which the electric vacuum cleaner 100 in the upright state is being charged as shown in FIG. 17, In a state where the direction of the connection terminal portion 82a is directed backward (reverse direction), The extension member 80 is attached to the vertical portion 72. that is, From the state shown in Figure 16, Until the connection between the first charging terminal 73 (see FIG. 15) and the relay terminal 82 is released, The extension member 80 is pulled upward toward the extension. and, Will extend the member 80, The tube 81 is used as an axis to rotate the relay terminal 82 toward the rear side. Descend until it touches the top 72a, It becomes the state shown in FIG. 18.  [0084] And, Remove the extension tube 300 from the electric vacuum cleaner 100, The electric vacuum cleaner 100 is directly connected to the standard suction port 400. and, The user lowers the body terminal portion 17 of the electric vacuum cleaner 100 connected to the standard suction port 400 from above the first charging terminal 73, Thereby, the first charging terminal 73 is connected to the body terminal portion 17. in this way, In the charging station 70 of this embodiment, The orientation of the extension member 80 can be changed for storage, And the electric vacuum cleaner 100 can be charged in a handheld state. In addition, Since it is not necessary to store the extension member 80 in a place different from the charging station 70, Therefore, the convenience of use can be improved.  [0085] Again, Extension tube 300, It is stored in the extension tube holding portion 82c that can be held in the extension member 80. in this way, Since the extension member 80 can be held in the extension tube holding portion 82c of the charging station 70, Therefore, when the electric vacuum cleaner 100 is changed from an upright state to a hand-held state, The removed extension tube 300 can be quickly attached to the extension tube holding portion 82c and stored. In addition, When the electric vacuum cleaner 100 is changed from the hand-held state to the upright state, The extension pipe 300 can be detached from the extension pipe holding portion 82 c and quickly attached to the electric vacuum cleaner 100. In addition, Because the extension tube 300 can be maintained at a higher position than the ground, So it is easy for users to load and unload. Can improve ease of use. In addition, Since it is not necessary to store the extension tube 300 in a place different from the charging station 70, Therefore, the convenience of use can be improved.  [0086] FIG. 19, A cross-sectional view showing a connection state of the body terminal portion and the first charging terminal.  As shown in Figure 19, When the body terminal portion 17 is fitted to the first charging terminal 73, The body terminal 17d is in contact with the terminal 73c, In addition, the edge portion 17f of the body terminal 17d is lowered, and thereby the terminal 73c is deformed by being bent backward. Terminal 73c, Has the elasticity of pushing the bomb forward, Therefore, while the cleaner body 1 is installed on the charging stand 70, The body terminal 17d and the terminal 73c are maintained in a contact state, The battery 3 (see FIG. 3) is continuously charged.  [0087] In addition, First charging terminal 73, It is unevenly fitted to the body terminal portion 17, Therefore, for example, even when the user touches the cleaner body 1 during charging, The conduction state (contact state) between the body terminal 17d and the terminal 73c is not released. In addition, When the second charging terminal 83 (see FIG. 16) is connected to the body terminal portion 17, Even when the user touches the cleaner body 1 during charging, The conduction state (contact state) between the body terminal 17d and the terminal 73c is not released.  [0088] In the charging station 70 thus configured, Since the first charging terminal 73 is formed on the upper surface 72 a of the vertical portion 72, Therefore, when the first charging terminal 73 is mated with the body terminal portion 17, Will be close to the user ’s line of sight, Therefore, it is easy to insert the body terminal portion 17 into the first charging terminal 73, It is easy to mount the cleaner body 1 on the charging stand 70. In addition, In the charging station 70, Since the second charging terminal 83 forms the upper surface 83a1 (refer to FIG. 15), Therefore, when the second charging terminal 83 is mated with the body terminal portion 17, Will be closer to the user ’s line of sight, Therefore, it is easy to insert the body terminal portion 17 into the second charging terminal 83, It is easy to mount the cleaner body 1 on the charging stand 70.  [0089] In addition, In the charging station 70, The first charging terminal 73 is formed on the upper surface 72 a of the vertical portion 72. that is, Since the first charging terminal 73 is formed higher than the ground, Therefore, it is difficult for the first charging terminal 73 to accumulate garbage, And can reduce the dust from the ground and the situation of attachment. In addition, In the charging station 70, The second charging terminal 83 is formed on the upper surface 83 a 1 of the extension member 80. that is, Since the second charging terminal 83 is formed higher than the ground, Therefore, it is difficult for the second charging terminal 83 to accumulate garbage, And can reduce the dust from the ground and the situation of attachment.  [0090] In addition, In the electric vacuum cleaner 100 installed on the charging stand 70, The first charging terminal 73 or the second charging terminal 83 is located near the center of gravity of the electric vacuum cleaner 100 (the position of the electric blower 40 and the battery 3), Therefore, it is possible to receive the first charging terminal 73 near the center of gravity. Second charging terminal 83, Thereby, the vacuum cleaner body 1 can be stably held on the charging stand 70 during charging.  [0091] In addition, Since the electric cleaner 100 is applied to the charging station 70, Can be charged while the dust box 2 is removed, Therefore, the dust box 2 is washed, It can also be charged while dry.  [0092] In addition, When the electric vacuum cleaner 100 is charged on the charging station 70 in a hand-held state, The standard suction port 400 is not brought into contact with the mounting surface 71 a of the base portion 71 (see FIG. 18). In addition, Because the first charging terminal 73 is facing up, Therefore, the main body terminal portion 17 is connected to the first charging terminal 73 from above. With this, Since the weight of the electric vacuum cleaner 100 can be concentrated on the first charging terminal 73, Therefore, the body terminal portion 17 and the first charging terminal 73 can be reliably connected.  [0093] Again, Although not shown, However, when the electric vacuum cleaner 100 is charged in an upright state, Also with the same mechanism as in Figure 19, The body terminal portion 17 of the electric vacuum cleaner 100 is connected to the second charging terminal 83. With this, Even when the body terminal portion 17 is connected to the second charging terminal 83, The same effects as those obtained when the first charging terminal 73 is connected to the body terminal portion 17 can also be obtained.  [0094] In addition, In the charging station 70, When the electric vacuum cleaner 100 is connected with the standard suction port 400 for charging, Since it can be supported by the mounting surface 71a of the base 71, Therefore, the electric vacuum cleaner 100 can be supported by two parts of the first charging terminal 73 and the standard suction port 400. The electric vacuum cleaner 100 can be stably held on the charging stand 70.  [0095] Figure 20, This figure shows how to use the vacuum cleaner in the upright position to clean the floor.  As shown in Figure 20, When the electric vacuum cleaner 100 is brought into an upright state, And make the electric vacuum cleaner 100 protrude more forward than the user to clean the ground, The user is holding the second holding portion 12a2 of the handle portion 12, While moving the electric vacuum cleaner 100 forward and backward. In addition, Although not shown, When the electric vacuum cleaner 100 is placed on the user's side to clean the ground, The user is holding the first grip portion 12a1 of the grip portion 12, While moving the electric vacuum cleaner 100 forward and backward. in this way, When the user cleans the ground, Cleaning can be performed by changing the position of the handle portion 12.  [0096] Figure 21, This figure shows how to use the vacuum cleaner in an upright position when cleaning high places.  Alas, For an electric vacuum cleaner whose center of gravity is on the front side when it is in an upright state (see Patent Document 1), When the electric vacuum cleaner 100 is cleaned at a height higher than the ground, Since it is necessary for the user to lift the front end of the electric vacuum cleaner 100 upward, Therefore, it is easy to cause a burden on the wrist.  Therefore, As shown in Figure 21, The electric blower 40 (refer to FIG. 4) or the battery 3 which is the weight of the electric vacuum cleaner 100 is located near the handle 12 (close to the hand), Therefore, the center of gravity G of the electric vacuum cleaner 100 is close to the user's hand. With this, Even when the electric vacuum cleaner 100 is set upright, When the electric vacuum cleaner 100 is cleaned higher than the ground, Also easy to clean, And can improve the convenience. In Figure 21, Although the case of cleaning the steps is described as an example, However, it is also effective when the electric cleaner 100 is lifted and the panel of the air conditioner is cleaned.  [0097] Next, Various application mouthpieces connected to the electric cleaner 100 will be described. In the aforementioned electric vacuum cleaner 100, It is possible to connect and replace various application mouthpieces as accessories for cleaning.  Figure 22, Is a sectional view showing a standard suction port with an opening and closing member installed, (a) when moving forward, (b) is against a wall, (c) Backward. also, In Figure 22, The illustration of a motor that drives the rotating brush or a substrate that controls the rotating brush is omitted.  [0098] As shown in FIG. 22 (a), Standard suction port 400, The system is configured with a mouthpiece housing 401, The first brush 402 driven by a motor (not shown), The second brush 403 rotated by friction with the ground.  [0099] Suction housing 401, The following is open, In addition, there is a space for accommodating the first brush 402 and the second brush 403. No. 2 brush 403, The rear part of the first brush 402 is arranged with a gap therebetween.  [0100] In addition, On the front of the mouthpiece housing 401, An opening and closing member 404 is provided. Opening and closing member 404, It has a rotating shaft 404a. In addition, Opening and closing member 404, Has a protrusion 404b extending perpendicular to the axial direction of the rotation shaft 404a, An opening / closing body 404 c extending from the rotation shaft 404 a in a direction opposite to the protrusion 404 b is directed. Protrusion 404b, It consists of a rigid plate-shaped member. Opening and closing body 404c, It is constructed by overlapping the front and rear bristles 404c1 and the rear side with a rubber plate 404c2.  [0101] As shown in FIG. 22 (a), When the standard suction port 400 is advanced, By the friction between the bristles 404c1 and the ground, And the suction of the electric blower 40, The opening and closing body 404c is turned counterclockwise, On the other hand, the lower part of the front face of the suction case 401 is opened. By thus opening the opening and closing body 404c, Large garbage (dust) located in front of the standard suction port 400 can be sucked in.  [0102] As shown in FIG. 22 (b), In the case where the standard suction port 400 abuts against a wall, First of all, The front end (upper end) of the protrusion 404b abuts against the wall. and, When the standard suction port 400 is pressed further towards the wall, With this pressing force, The opening and closing member 404 rotates in a clockwise direction, and the opening and closing body 404c moves forward. With the opening and closing body 404c moving forward, The opening 401a in the lower part of the front face of the suction case 401 is closed. By so constituting, Capable of sucking in and removing rubbish from the wall (corner). In addition, By moving the standard suction port 400 in the left-right direction, It is possible to more reliably remove rubbish from the wall.  [0103] As shown in FIG. 22 (c), When the standard suction port 400 is advanced backward, By the friction between the bristles 404c1 and the ground, The opening and closing body 404c is turned clockwise, The opening / closing body 404c moves forward. With this, As the static pressure in the suction nozzle housing 401 rises, Thereby, garbage can be sucked in reliably.  [0104] In addition, For wireless electric cleaner 100, The suction force is weaker than that of an electric vacuum cleaner supplied with electricity from a household outlet. therefore, In the standard suction port 400, When moving forward (refer to Figure 22 (a)), The front (opening 401a) of the mouthpiece housing 401 is open, Therefore, the operation force can be made light, And able to suck big trash. In addition, When moving backward (refer to Figure 22 (c)), The opening and closing member 404 is closed and the static pressure is increased, Therefore, it is possible to surely inhale, for example, sand particles in a carpet. In addition, By forming the standard suction port 400 to be smaller than the suction port of an electric vacuum cleaner connected to a power supply supplied from a household outlet, Can reduce air leakage from the standard suction port 400, And can make the static pressure easily distributed evenly.  [0105] Figure 23, Department means mouthpieces for various applications, (a) A perspective view showing a gap suction mouth, (b) is a perspective view showing a small suction mouth, (c) is a perspective view showing a broom-type suction mouth, (d) is a top view of (c).  As shown in Figure 23 (a), Gap suction 500, Is accumulated between furniture, Garbage person waiting for clearance between furniture and wall.
