In addition, the dust box 2 is arranged in front of the motor housing portion 11 with the axial direction as the front-rear direction, and has a substantially cylindrical outer cylinder 2a. In addition, a substantially rectangular inflow port 2b connected to the introduction pipe 14 is formed on the upper surface (side surface) of the dust collection box 2. After the dust-containing air flowing into the inlet 2b is separated from the air in the dust collecting box 2, the air separated from the dust is discharged from the rear (back) of the dust collecting box 2.　　 FIG. 35 is an external view of the dust box 2, (a) is the front view when the upper side (refer to FIG. 2) is the front side, and (b) is the right side view when the upper side is the front side. In addition, FIG. 36 is a cross-sectional view of line II and JJ line shown in FIG. 35, (a) is a cross-sectional view of line II shown in FIG. 35 (a), and (b) is FIG. 35 (b) The sectional view of the JJ line shown. The dust box 2 is composed of an outer cylinder 2a and an inner cylinder 200 described later. The outer cylinder 2a is substantially cylindrical, as described above, and has a substantially rectangular inflow port 2b on the upper surface (cylindrical side surface), opening front and rear, a filter 5 described later on the rear, and a cover 2c on the front. Further, as shown in FIG. 36(a), the rear part is divided into a separation part 2a1 that swirls and separates the air containing dust sucked by the inlet 2b, and the front part is a storage part 2a2 that contains the separated dust. [0022] The inner cylinder 200 is substantially cylindrical as shown in FIG. 36, and is provided with a cylinder portion 210 provided with a mesh portion 220 at the upper portion (rear), and is opened at the lower portion (front) although the structure is omitted. At the time of the cover 2c, the dust piston 240 is pushed out. The piston part 240 is contained in the umbrella part 230 provided in the lower part (front) of the cylindrical part 210, and the umbrella part 230 is provided with the ring-shaped rib (250a, 250b, 250c). The ring-shaped ribs are provided so that the dust transported to the storage 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 ribs The 250c is provided in the piston part 240, but its diameter, position, and number are not limited thereto. Among the plurality of ring-shaped ribs, the ring-shaped rib 250a can change the ratio of the flow swirling in the separation part 2a1 to the flow conveyed toward the storage part 2a2, which also effectively suppresses the dust from returning to the separation part 2a1 side. In order to obtain such an effect, the ring-shaped rib 250a is provided at a position immediately adjacent to the substantially rectangular inflow port 2b provided in the outer cylinder 2a. The inflowing air (including dust) is bounded by an annular rib 250a, the upper side system can strengthen a part of the flow swirling around the separation portion 2a1, and the lower side system becomes a flow that is directly transported toward the housing portion 2a2. In the case where there is no annular rib 250a, the flow swirling in the separation portion 2a1 is turned toward the accommodation portion 2a2 while swirling, and returns to the separation portion 2a1 from the accommodation portion 2a2 while passing through the piston portion 240. At this time, although the return of dust is suppressed by the circular ring-shaped ribs 250b and 250c, the dust may return to the separation part 2a1. By providing the ring-shaped ribs 250a as in the present embodiment, the swirling flow swirling in the separation portion 2a1 can be strengthened, and the returning dust can be suppressed from adhering to the mesh portion 220 of the inner cylinder 200. [0023] In this embodiment, although the annular rib 250a is provided at a position slightly adjacent to the inlet 2b, it is not limited to this and may be provided at a position that bisects the inlet 2b. In addition, although the ring-shaped rib 250a is provided in the umbrella part 230, it may be provided in the cylindrical part 210 provided with the mesh part 220 instead of the umbrella part 230. [0024] In addition, a cover 2c that opens and closes when dust accumulated in the dust collecting box 2 is discarded in front of the dust collecting box 2 is rotatably supported through a hinge portion 2d. In addition, a cover lock mechanism 2e including a release button 2f for releasing the lock of the cover 2c is provided on the upper portion of the cover 2c.　　 [0025] Inside the dust collecting box 2, the screen 5 is accommodated at the rear end of the outer cylinder 2a in the axial direction. The screen 5 is configured to be folded into a folded shape, the area of the screen can be increased, and the pressure loss caused by the screen 5 can be reduced. In addition, by pressing the button 5a provided on the upper part of the dust box 2, the filter 5 can be detached. On the opposite side to the button 5a (under the arrow in the figure), there is a device for removing dust from the cleaner body 1 The button 5b of the box 2 is removed.　　 In addition, the filter 5 is, 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 particle size 0. 3μm particles have 99. Particle capture rate above 97%, And the air filter with an initial pressure loss of 245Pa or less. 　　Again, For the internal mechanism of the dust box 2, It can be configured according to Japanese Patent Laid-Open No. 2016-137165. 　　[0026] Figure 3, This is a perspective view of the electric vacuum cleaner in a state where the aforementioned lid lock mechanism 2e is operated to open the lid 2c. Figure 4 is a longitudinal sectional view of the electric vacuum cleaner, Figure 5 is a side view. 　　As shown in Figures 3 to 5, Electric vacuum cleaner 100, The dust collecting box 2 is installed below the body portion 10 and in front of the motor housing portion 11. at this time, If the dust box 2 is installed on the vacuum cleaner body 1, Then, the lid lock mechanism 2e is provided on the upper side indicated by the arrow in the figure (substantially opposite to the main body 10), A hinge portion 2d is provided on the lower side (the side not facing the body portion 10). In addition, The release button 2f provided in the lid lock mechanism 2e is located farther back than the side surface of the body portion 10 located immediately to the left of the cleaner body 1 (body portion 10). In other words, it is provided at a position that does not protrude from the side surface of the main body 10. This is because the release button 2f is provided at a position protruding more than the side surface of the main body 10, There is a possibility that the cover 2c will be lifted during cleaning However, by preventing the release button 2f from protruding from the side of the body 10, It can prevent the release of the cover 2c, And can prevent misoperation. E.g, During cleaning, The vacuum cleaner body 1 may come into contact with furniture or the like. at this time, Since the release button 2f is provided on the back side of the side surface of the main body 10, Therefore, it is possible to reduce the risk of the release button 2f accidentally touching the furniture, Or the cover 2c may open unexpectedly. The position of the release button 2f provided in the lid lock mechanism 2e is not limited to this, It may be provided at a position immediately adjacent 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 10, Thereby, the dust in the dust box 2 can be easily discharged in a single operation in a waste disposal place such as a trash can. In addition, The dust box 2 is installed in the state of the vacuum cleaner body 1, And the opening of the dust box 2 in the state where the cover 2c is opened by the cover lock mechanism 2e, It is opened in the same direction as the connection port 10a of the cleaner body 1 as an opening. With this, Able to discharge dust from the dust box 2, In addition, dust that may remain in the introduction pipe 14 can also be discharged. 　　And, The dust box removal button 5b shown in the aforementioned Figure 4 and Figure 5, By sliding in the direction indicated by the arrow 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), it is possible to carry only the dust box 2 and discard garbage. In addition, By only removing the dust box 2 from the vacuum cleaner body 1, If the dust box 2 is dirty, it can be easily washed with water, 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 on the cleaner body 1, Dispose of garbage in the state of removal and the state of users, Therefore, it is possible to provide an electric vacuum cleaner with good convenience in use. 　　[0027] In addition, In the dust box 2, The maintenance brush is installed for 2s in a freely detachable manner. The maintenance brush for 2s, It is arranged at a position that is difficult to see from the outside when the dust box 2 is mounted on 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, At the motor housing portion 11 of the body portion 10, The electric blower 40 is accommodated. In the motor housing portion 11, Below the electric blower 40, A body substrate 50 (control substrate) that controls the cleaner body 1 is housed. 　　[0029] Electric blower 40, The rotation drive shaft 40a is arranged horizontally so as to face the front-rear direction. In addition, The air discharged from the electric blower 40, The body substrate 50 disposed below the electric blower 40 flows, The main body substrate 50 is cooled. 　　 [0030] The main body substrate 50, It is divided up and down and is configured as 2 segments, Mainly install parts on the opposite side. The air discharged from the electric blower 40, It flows almost in such a way that the components (heat-generating components) of each body substrate 50 that are arranged to face each other are cooled. 　　[0031] In addition, Electric blower 40 and body substrate 50, It is arranged so as to overlap in the vertical direction. therefore, The size in the front-rear direction can be shortened. In addition, Electric blower 40 and body substrate 50, It is located below the first grip portion 12a1 of the handle portion 12. With this, When the user grasps the grip 12a and operates, The center of gravity of the electric vacuum cleaner 100 is located near the lower portion of the first grip 12a1, Therefore, when the front end of the electric vacuum cleaner 100 is used upward, The electric vacuum cleaner 100 can be stably held. 　　[0032] In addition, Between the first grip portion 12a1 and the upper surface 11c of the motor housing portion 11, A gap 12c with a width dimension H1 for inserting a hand is formed.

In addition, Tube 81, The second charging terminal 83 is held at the upper end in the axial direction. By making the tube 81 made of metal, Can make the charging station 70 appear slim in appearance, Also, when manufacturing the extension member 80, a large mold is not required. also, Tube 81, Department is not limited to metal, It can also be made of synthetic resin. 　　[0065] In addition, Tube 81, The connecting portion 81s protruding downward from the relay terminal 82, The coupling holding portion 72c integrally formed with the vertical portion 72 is coupled. Link holding portion 72c, It is formed into a slender cylindrical shape in the axial direction, An insertion hole 72c1 into which the connecting portion 81s of the tube 81 is inserted is formed on the upper surface 72a.

[0067] The connection terminal portion 82a, The system is formed to protrude in a direction orthogonal to the axial direction of the tube 81, A terminal portion connected to the first charging terminal 73 is formed on the lower surface. The terminal part, Although not shown, However, it has the same structure as the body terminal portion 17 shown in FIG. 14. 　　[0068] The holding member 82b, It has a flange 82b1 extending toward the connecting terminal portion 82a From the flange 82b1 upward, it is formed in a truncated cone shape in a side view, and is fixed to the cylinder 82b2 of the tube 81. 　　[0069] So, Relay terminal 82, When the tube 81 is inserted into the coupling and holding portion 72c and installed, The connection terminal portion 82a and the first charging terminal 73 are connected and electrically connected. 　　[0070] The extension tube holding portion 82c, It is formed in front of the connection terminal 82a, It also has a pair of holding pieces 82c1 that hold and hold the extension tube 300 (see Fig. 1(a)) from the left and right sides. 82c1. A pair of holding pieces 82c1 82c1, It is configured to be able to flex and deform, And push the extension tube 300 (refer to FIG. 1(a)) from the gap 82c2, With this, the extension tube 300 can be held on the holding piece 82c1 82c1. 　　[0071] The extended hose holding portion 82d, When the user holds the extension hose 800 (see Figure 25), And has a front holding piece 82d1 Lower holding piece 82d2. 　　[0072] Front holding piece 82d1, It is a plate-shaped one that is clamped and held on the side of the tube 81, It is formed so as to protrude upward on the upper surface of the connection terminal portion 82a. In addition, The front end (upper end) of the front holding piece 82d1, The system is formed to bend toward the tube 81 side. 　　[0073] Lower holding piece 82d2, Those who support the lower part of the extension hose 800, It also has a lower support portion formed from the connection terminal portion 82a to the tubular body 82b2. In addition, The lower holding piece 82d2, The connection terminal portion 82a and the holding member 82b are connected, The strength of the relay terminal 82 is improved. 　　[0074] The second charging terminal 83, It has the same structure as the first charging terminal 73, The electric vacuum cleaner 100 in an upright state (refer to FIG. 1(a)) can be charged in a standing state. In addition, The second charging terminal 83, The system has a holding portion 83a held by the upper end of the tube 81. On the upper surface 83a1 of the holding portion 83a, The second charging terminal 83 is formed facing upward. 　　[0075] In addition, In front of the holding portion 83a, The peripheral surface of the dust box 2 that receives the electric vacuum cleaner 100 is formed, In addition, the suppression unit 83b that suppresses the shaking of the electric vacuum cleaner 100 is provided. In front of the suppression unit 83b, The system is formed so as to curve toward the front while expanding toward the left and right. 　　[0076] Picture 16, This is a side view showing the charging station of the electric vacuum cleaner. 　　As shown in Figure 16, Charging station 70, 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 (see FIG. 15) is fitted to the relay terminal 82, The first charging terminal 73 and the relay terminal 82 are electrically connected. In addition, Relay terminal 82, It is electrically connected by a wire (not shown) passing through 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 surface (back surface) of the connection holding portion 72c, The position of the rear surface (rear surface) of the extension member 80 is substantially the same. In addition, Extension 71e, It is constructed as shown in the side view of FIG. 16, It protrudes rearward than the connection holding portion 72c and the extension member 80. 　　[0078] In addition, The upper surface 83a1 of the holding portion 83a, The system is slightly inclined so as to descend toward the front. In addition, The second charging terminal 83, It is arranged obliquely along the inclination of the upper surface 83a1. 　　[0079] Figure 17, This is a side view when the electric vacuum cleaner is installed upright on the charging stand. also, The arrow in the direction of Figure 17, The system 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, The second charging terminal 83 is connected to charge the battery. at this time, The user puts the extension tube 300 downward while holding the handle 12, Then, the cleaner body 1 is lowered from above the second charging terminal 83, Thereby, the body terminal 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 main body terminal 17 can be reliably connected to the second charging terminal 83. 　　[0080] In addition, The dust box 2 is connected to the suppression unit 83b, The extension tube 300 is held by the extension tube holding portion 82c of the extension member 80. In addition, Part of the standard suction port 400, It is in contact with the mounting surface 71a 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, It is also possible to stably hold the electric vacuum cleaner 100 on the charging stand 70. 　　[0081] In addition, When the upright electric vacuum cleaner 100 is charged by the charging stand 70, The electric vacuum cleaner 100 is oriented in the vertical direction (up and down direction), The posture leaning forward only at an angle α is maintained. in this way, The electric vacuum cleaner 100 is maintained in the forward leaning posture, With this, the center of gravity of the electric vacuum cleaner 100, Will be more forward than holding the electric vacuum cleaner 100 upright, Therefore, it is possible to prevent the electric vacuum cleaner 100 from falling backward. 　　[0082] Again, Charging station 70, Is not connected to the power cord 76, When charging of the battery 3 is not performed, It can also be used as a stand for storing the electric vacuum cleaner 100. 　　[0083] Figure 18, This is a side view when the electric vacuum cleaner is attached to the charging stand in a hand-held state. 　　As shown in Figure 18, The electric vacuum cleaner 100 is in a handheld state, Connected to the first charging terminal 73. that is, The state shown in FIG. 17 in which the electric vacuum cleaner 100 in the upright state is charged, In a state where the direction of the connecting terminal portion 82a is directed to the rear (reverse direction), The extension member 80 is attached to the vertical portion 72. that is, Since 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, Extend member 80, The tube 81 is used as an axis to rotate the relay terminal 82 toward the rear side, Down to 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 17 of the electric vacuum cleaner 100 to which the standard suction port 400 is connected from above the first charging terminal 73, As a result, the first charging terminal 73 is connected to the body terminal 17. in this way, In the charging stand 70 of this embodiment, The orientation of the extension member 80 can be changed for storage, In addition, the electric vacuum cleaner 100 can be charged in a hand-held state. In addition, Since it is not necessary to store the extension member 80 in a place different from the charging stand 70, Therefore, the convenience of use can be improved. 　　[0085] Again, Extension tube 300, It can be held and held by the extension tube holding portion 82c of the extension member 80. in this way, Since the extension member 80 can be held by the extension tube holding portion 82c of the charging stand 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 a hand-held state to an upright state, The extension tube 300 can be removed from the extension tube holding portion 82c and quickly attached to the electric vacuum cleaner 100. In addition, Because the extension tube 300 can be kept at a higher position than the ground, Therefore, it is easy for users to load and unload, Can improve the ease of use. In addition, Since there is no need to store the extension tube 300 in a place different from the charging station 70, Therefore, the convenience of use can be improved. 　　[0086] Figure 19, It is a cross-sectional view showing the connection state of the main body terminal portion and the first charging terminal. 　　As shown in Figure 19, When the body terminal portion 17 is fitted into the first charging terminal 73, The body terminal 17d contacts the terminal 73c, The edge 17f of the body terminal 17d is lowered, and the terminal 73c is flexed and deformed toward the rear. Terminal 73c, It has the elasticity of pushing forward towards the front, Therefore, while the cleaner body 1 is installed on the charging stand 70, The body terminal 17d and the terminal 73c are maintained in contact, The battery 3 (see FIG. 3) is continuously charged. 　　[0087] In addition, The first charging terminal 73, It is concave and convex fitting with the body terminal 17 Therefore, for example, even if 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 17, Even if 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 stand 70 thus constructed, Since the first charging terminal 73 is formed on the upper surface 72a of the vertical portion 72, Therefore, when the first charging terminal 73 is engaged with the body terminal 17, Will be located close to the user’s line of sight, Therefore, it is easy to insert the body terminal 17 into the first charging terminal 73, Moreover, it is easy to install 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 (see FIG. 15), Therefore, when fitting the second charging terminal 83 to the body terminal 17, Will be closer to the user’s line of sight, Therefore, it is easy to insert the body terminal 17 into the second charging terminal 83, Moreover, it is easy to install 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 at a higher position than the ground, Therefore, the first charging terminal 73 is not prone to accumulation of garbage, And can reduce the dust from the ground and attached to the situation. 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 at a higher position than the ground, Therefore, the second charging terminal 83 is not prone to accumulation of garbage, And can reduce the dust from the ground and attached to the situation. 　　[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 close to the center of gravity of the electric vacuum cleaner 100 (position of the electric blower 40 and the battery 3), Therefore, the first charging terminal 73 can be received near the center of gravity, The second charging terminal 83, Thereby, the cleaner body 1 can be stably held on the charging stand 70 during charging. 　　[0091] In addition, Since the charging station 70 uses the electric vacuum cleaner 100, It can be charged with the dust box 2 removed, Therefore, after washing the dust box 2, It can also be charged during drying. 　　[0092] In addition, When charging the electric vacuum cleaner 100 on the charging stand 70 in a hand-held state, The standard suction port 400 is not in contact with the mounting surface 71a of the base 71 (see FIG. 18). In addition, Since the first charging terminal 73 faces upward, 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 the illustration is omitted, However, when charging the electric vacuum cleaner 100 in an upright state, Also by the same mechanism as in Figure 19, The main 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 17 is connected to the second charging terminal 83, It is also possible to obtain the same effect as when the first charging terminal 73 is connected to the main body terminal 17. 　　[0094] In addition, In the charging station 70, When charging the electric vacuum cleaner 100 with the standard suction port 400 connected, Since it can be supported by the mounting surface 71a of the base 71, Therefore, the electric vacuum cleaner 100 can be supported by the first charging terminal 73 and two parts of the standard suction port 400, In addition, the electric vacuum cleaner 100 can be stably held on the charging stand 70. 　　[0095] Figure 20, This is a view of the use of the electric vacuum cleaner in an upright state when cleaning the ground. 　　As shown in Figure 20, When the electric vacuum cleaner 100 is in 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 grip portion 12a2 of the handle portion 12 while While moving the electric vacuum cleaner 100 forward and backward. In addition, Although not shown, When the electric vacuum cleaner 100 is positioned on the side of the user to clean the ground, The user is holding the first grip portion 12a1 of the grip portion 12 while While moving the electric vacuum cleaner 100 forward and backward. in this way, When the user sweeps the ground, The position of the handle portion 12 can be changed for cleaning. 　　[0096] Figure 21, It is a view of the use of the vacuum cleaner in an upright state when cleaning high places. 　　Again, In the case of an electric vacuum cleaner whose center of gravity is on the front end side when it is in an upright state (see Patent Document 1), When cleaning the electric vacuum cleaner 100 higher than the ground, Since the user needs 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 close to the handle portion 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 in an upright state, Make the electric vacuum cleaner 100 clean higher than the ground, It is also easy to clean, And can improve the ease of use. In Figure 21, Although the case of cleaning the stairs is taken as an example for explanation, However, it is also effective to lift the electric vacuum cleaner 100 to clean the panel of the air conditioner. 　　[0097] Then, Various suction mouth bodies connected to the electric vacuum cleaner 100 will be described. In the aforementioned electric vacuum cleaner 100, It is possible to connect and replace various application suction nozzles as accessories to perform cleaning. 　　Figure 22, Is a cross-sectional view showing a standard suction port with an opening and closing member installed, (a) When the system is moving forward, (b) When it touches the wall, (c) When going backward. also, In Figure 22, The illustration of the motor driving the rotating brush or the substrate controlling the rotating brush is omitted. 　　[0098] As shown in Figure 22 (a), Standard suction port 400, The system is configured to have a suction port housing 401, The first brush 402 driven by a motor (not shown), The second brush 403 that rotates by friction with the ground. 　　[0099] Suction port housing 401, The following is open, It also has a space for storing the first brush 402 and the second brush 403. 2nd brush 403, It is arranged behind the first brush 402 with a gap. 　　[0100] In addition, In front of the suction port housing 401, The opening and closing member 404 is provided. Opening and closing member 404, The system has a rotating shaft 404a. In addition, Opening and closing member 404, It has a protrusion 404b extending perpendicular to the axial direction of the rotating shaft 404a, The opening-and-closing body 404c extends from the rotating shaft 404a in the opposite direction to the protrusion 404b. Protrusion 404b, It consists of a rigid plate-shaped member. Opening and closing body 404c, The structure is formed by stacking front and back with the bristle portion 404c1 on the front side and the plate portion 404c2 made of rubber on the rear side. 　　[0101] As shown in Figure 22(a), When advancing the standard suction port 400, By the friction between the bristle portion 404c1 and the ground, And the suction power of the electric blower 40, The opening and closing body 404c rotates counterclockwise, On the other hand, the lower part of the front face of the mouthpiece case 401 is opened. By opening the opening and closing body 404c in this way, Large garbage (dust) located in front of the standard suction port 400 can be sucked in. 　　[0102] As shown in Figure 22(b), When the standard suction port 400 abuts on the wall, First of all, The front end (upper end) of the protrusion 404b will abut against the wall. and, When the standard suction port 400 is further pressed toward the wall, Then by the pressing force, The opening and closing member 404 rotates clockwise, and the opening and closing body 404c moves forward. By opening and closing body 404c moving forward, The opening 401a at the front lower part of the suction port case 401 is closed. By constructing like this, Ability to inhale and remove trash on the walls (corners). In addition, By moving the standard suction port 400 in the left-right direction, It can remove the garbage on the wall more surely. 　　[0103] As shown in Figure 22(c), When the standard suction port 400 is advanced, By the friction between the bristle portion 404c1 and the ground, The opening and closing body 404c rotates clockwise The opening and closing body 404c moves forward. With this, As the static pressure in the suction port housing 401 rises, By this, garbage can be inhaled reliably. 　　[0104] In addition, As far as the wireless electric vacuum cleaner 100 is concerned, The suction power is weaker than that of an electric vacuum cleaner that supplies power from a household outlet. therefore, In the standard suction port 400, When advancing (refer to Figure 22(a)), The front face (opening 401a) of the suction port case 401 is open, So it can make the operation force light, And be able to absorb big garbage. In addition, When going backward (refer to Figure 22(c)), The opening and closing member 404 is closed and the static pressure increases, Therefore, it is possible to inhale the sand particles in the carpet, for example. In addition, By configuring the standard suction port 400 to be smaller than the suction port connected to an electric vacuum cleaner that supplies power from a household outlet, Can reduce the air leakage from the standard suction port 400, And can make the static pressure easy to distribute evenly. 　　[0105] Figure 23, Department means various application mouthpieces, (a) shows a perspective view of the gap suction port, (b) is a perspective view showing a small suction port, (c) is a perspective view showing a broom type suction port, (d) is a plan view of (c). 　　As shown in Figure 23(a), Gap suction port 500, Department draws accumulated between furniture, Junks such as gaps between furniture and walls.
