Figure 1 discloses a prior art surface cleaning apparatus in which the handle assembly cannot rotate relative to the main body. Referring to fig. 2, the arrow direction is the equipment running direction. Fig. 2 discloses a device comprising a body 2 and a handle assembly 1. The handle assembly may be provided with a control switch for controlling the device. Referring to fig. 3-12, the handle assembly 1 includes a rotating portion 11 and a grip portion 12. Of course, a connecting portion 13 connecting the rotating portion 11 and the grip portion 12 may be further included. The swivel part 11 is rotatably mounted to the body 2 or the extension rod 4 about a connection axis O such that the handle assembly 1 can swivel in a first plane a substantially perpendicular to the working surface B. The connection axis may be located within the swivel part. The connection axis may also be located outside the rotary part (not shown in the figures) and in the area defined between the rotary part and the grip part. Specifically, when the connection axis is located outside the rotating portion, the rotating portion slides along an arc relative to the main body or the extension rod, and the entire handle assembly rotates around the connection axis relative to the main body or the extension rod. The body 2 may be a single body, and the body 2 may further include a connecting rod 21, in which case the handle assembly 1 is rotatably mounted to one end of the connecting rod 21. The rotating portion 11 is a part of the handle assembly 1, and may be a small part or a large part, and the volume of the rotating portion 11 is not limited here, and only needs to be pivotable with respect to the main body 2 or the extension rod 4. A grip portion 12 is connected to the rotating portion 11, the grip portion 12 being configured to be gripped by a user. The connecting portion 13 is used to connect the rotating portion 11 and the connecting portion 13. The connecting portion 13 is a place which is rarely touched by a user in normal use, but may be touched by the user occasionally, but mainly plays a connecting role rather than being mainly held. The grip portion 12, the connecting portion 13, and the rotating portion 11 may be integrally formed, or may be provided separately. At least a part of the holding space is defined among the rotating portion 11, the connecting portion 13 and the holding portion 12 to facilitate the user's holding.

Referring to fig. 7 to 8, the direction of the arrow in the drawings is a direction perpendicular to the grip portion, a first plane a passing through at least a part of the grip portion 12 is defined as a predetermined plane, an area formed by the movement of the grip portion 12 in a direction perpendicular to the axis of the grip portion 12 is defined as a first area C within the predetermined plane, and the connection axis O is located in the first area C. The connection axis O may be perpendicular to the first plane a and may also be at an angle to the first plane a, preferably the connection axis O is perpendicular to the first plane a. Referring to fig. 7, the axial direction perpendicular to the grip portion 12 is better defined when the grip portion is of a relatively straight configuration. Referring to fig. 8, when the grip portion 12 includes a certain curvature, the two ends of the grip portion 12 may be connected to each other, and then the direction perpendicular to the connection line is taken as the moving direction. The grip portion 12 is actually the position where the user's hand is primarily or permanently held during operation, and other structures for adding grip contouring should not be included in the grip portion 12. The predetermined plane is preferably a plane in the direction of travel of the apparatus, which is substantially perpendicular to the working surface B. The grip portion 12 is cut out of this predetermined plane, and both the grip portion 12 and the connection axis O can be included in this plane, and if the rotation portion 11 is located directly below the grip portion 12, the rotation portion 11 is also included in this plane.

Referring to fig. 9-11, the connecting shaft 26 of the handle assembly 1 is disposed opposite to the grip portion 12, and the point of application of force can be concentrated at a position corresponding to the hand, i.e., when the hand naturally holds the grip portion 12, the arm, the hand and the connecting shaft 26 are substantially in the same linear direction, which can make the user more labor-saving when operating the apparatus. Especially, when the force applied to the handle assembly 1 by the main body 2 is concentrated on the rotating part 11 in the process of pushing and pulling the device, the force applied to the handle assembly 1 by the main body 2 is basically not required to be applied by the wrist of the user because the rotating part 11 is rotatable relative to the main body, and only the arm force of the user is required to be transmitted to the rotating part 11 of the handle assembly 1 through the hand, which is equivalent to that the user only performs the action of swinging the arm, and the wrist has basically no force. Therefore, the user can feel more labor-saving in the operation process.

However, in the prior art, the handle assembly 1 cannot rotate relative to the main body 2, and the joint between the handle assembly 1 and the main body 2 changes relative to the position of the hand of the user along with the forward and backward movement of the device, so that the user is required to adjust the position of the hand relative to the forearm, and thus the device is difficult to use.

Referring to fig. 11 and 12, in one implementation of the handle assembly 1, the handle assembly 1 comprises a substantially parallel rotation portion 11 and a grip portion 12, the handle assembly 1 further comprising a first connection portion 14, the first connection portion 14 connecting a first end of the grip portion 12 and a first end of the rotation portion 11. The first connection portion 14 is arc-shaped, but may have other shapes. Each of the diagrams a and b in fig. 12 has only one connecting portion.

Referring to fig. 11 and 12, in another implementation of the handle assembly 1, in addition to the first connecting portion 14, a second connecting portion 15 may be further included, and the second connecting portion 15 connects the second end of the grip portion 12 and the second end of the rotating portion 11. The second connecting portion 15 is arc-shaped, but may have other shapes. Fig. 11 and 12 c show two connecting portions.

Referring to fig. 11, the connection portion 13 includes a first connection portion 14 and a second connection portion 15, the first connection portion 14 connects first ends of the rotation portion 11 and the grip portion 12, the second connection portion 15 connects second ends of the rotation portion 11 and the grip portion 12, and the rotation portion 11, the first connection portion 14, the grip portion 12, and the second connection portion 15 together define a grip space. By adopting two connecting parts 13, the whole handle assembly 1 can be more stable and convenient to operate, because the user can operate the device through the connecting parts 13 except during normal use. The first connecting portion 14 and the second connecting portion 15 are each arc-shaped and form a ring shape in cooperation with the rotating portion 11 and the grip portion 12.

The grip portion 12 is configured to be inclined at an angle of not more than 20 degrees with respect to the working surface B when the handle assembly 1 is in the use state. It will be appreciated that the grip portion may be rotated to a position not exceeding 20 degrees from the work surface when the device is in use, regardless of how much the device is tilted relative to the work surface. Further, the grip portion 12 is configured to be substantially horizontal when the handle assembly 1 is in use, i.e. the grip portion may each be rotated to a position substantially parallel to a work surface. The use state is a state in which the main body 2 is inclined at 0 to 60 degrees with respect to the working surface B, and the user holds the grip portion 12 with a hand and pushes and pulls the apparatus in a relaxed state. In this state, the user can push and pull the device with the least force, which is more labor-saving.

The handle assembly 1 can be mounted to any device, and only the main body 2 of the device needs to have a certain angle relative to the working surface B during working, and a user can push and pull the main body 2 through the handle assembly 1 during working.

Referring to figure 13 there is disclosed a surface cleaning apparatus 100, the surface cleaning apparatus 100 comprising a main body 2, a cleaning head 3 and a handle assembly 1 according to any of the embodiments described above. The body 2 includes opposed proximal and distal ends 22, 23 along its length. The body 2 may include a connecting rod 21, it being understood that the connecting rod 21 is part of the body 2. The cleaning head 3 is disposed at the proximal end 22 for cleaning a surface to be cleaned. The cleaning head 3 may comprise a wiping piece such as a roller brush, a rag or the like. The cleaning head 3 can be moved repeatedly in the direction of travel to clean the surface to be cleaned. The handle assembly 1 comprises a rotary part 11 and a grip part 12, the rotary part 11 being rotatably mounted to the distal end 23 about a connection axis O. A grip portion 12 is connected to the rotating portion 11, the grip portion 12 being configured to be gripped by a user. The rotating portion 11 is a part of the handle assembly 1, and may be a small part or a large part, and the volume of the rotating portion 11 is not limited here, and only needs to be pivotable with respect to the main body 2. The rotary portion 11 may be formed integrally with the grip portion 12, or may be provided separately from the grip portion.

Surface cleaning apparatus 100 may include one or both of a cleaning liquid supply system including a cleaning liquid tank, a supply line, and a water pump, and a soil recovery system. The dirt recovery system comprises a recovery tank and also comprises a suction motor and a suction pipeline. The clean water tank may be provided in the main body 2 and the recovery tank may be provided in the main body 2 and may also be provided in the cleaner head 3. The suction motor may be provided in the main body 2 and may also be provided in the cleaner head 3. When the clean water tank, the sewage tank and the suction motor are all arranged in the main body 2, at this time, the weight of the whole main body 2 can be heavier, and the user can be labored in the operation.

The holding part 12 is rotatably arranged at the far end 23 of the main body 2 through the rotating part 11, and in the process that the main body 2 is pushed and pulled, because the handle is rotatable relative to the main body 2, the burden of a user holding the handle can be effectively reduced, and the user can drag the equipment with little force.

Referring to fig. 14-17, fig. 14 may be a first position of the user while in use, and fig. 15 may be a second position of the user while in use. The use state during normal cleaning may be that the cleaning device is pushed or pulled between the first position and the second position. To further reduce the user's effort in pushing and pulling the cleaning device, the handle assembly 1 may be further modified. The main body 2 or the extension bar 4 has an upright state (refer to fig. 13) and a use state (refer to fig. 14 and 15) with respect to the cleaning head 3, and when the main body 2 or the extension bar 4 is in the use state, the rotation section 11 is located below the grip section 12 in the vertical direction. The use state described here is a state in which the user holds the grip portion 12 with his hand and keeps a relatively relaxed state. Since the handle assembly 1 is rotatable, the device can be pushed and pulled regardless of the angle to which the handle assembly is rotated, only the force is different, and the use state refers to that the user can push and pull the device with the minimum force. In the above-mentioned usage state, the rotating portion 11 is located below the grip portion 12, where the below includes but is not limited to being located directly below the grip portion 12, and may also be slightly offset from some orientation, for example: referring to fig. 18-20, the rotating portion 11 is located directly below the grip portion. Referring to fig. 3 to 5, if the two connecting shafts 2, 6 are disposed outside the handle assembly 1, it can be understood that the rotating portion 11 is located below the grip portion 12 even though the rotating portion 11 is not located directly below the grip portion 12. However, if the rotating portion 11 and the grip portion 12 are placed in the same vertical plane, the connecting shaft 26 of the rotating portion 11 is located directly below the grip portion 12. With this arrangement, it is equivalent to disposing the connecting shaft 26 directly under the hand, and at this time, the user should be most labor-saving when operating the device, because the gravity on the main body 2 is concentrated at the connecting shaft 26 during the pushing and pulling process, and the connecting shaft 26 is located below the holding portion 12, so it is equivalent to carrying a heavy object with the hand, and if the handle assembly 1 cannot rotate, the gravity on the main body 2 is concentrated in front or oblique front of the holding portion 12 during the pushing and pulling process, and at this time, the user needs a large force during pushing and pulling, just like holding things with the hand at ordinary times, and should be most labor-saving when carrying.

It will also be appreciated that, with reference to the figures, the handle assembly 1 further comprises a limit formation 25, the limit formation 25 being configured to limit the angle of rotation of the handle assembly 1 such that the angle of rotation is less than 100 degrees. Further, it may be limited to 70 degrees. Still further, it may be limited to 45 degrees.

Referring to fig. 3-6, in one implementation, the distal end 23 of the main body 2 or the extension rod 4 includes a connection structure 24, the connection structure 24 defines a mounting slot to be pivotably connected with the rotation portion 11 by a connection shaft 26, and the distal end 23 is provided with a limit structure 25 defining a rotation angle of the handle assembly 1.

Referring to fig. 18-20, in one implementation, the distal end 23 of the main body 2 or the extension rod 4 includes a connecting structure 24, a portion of the connecting structure 24 extends into the interior of the handle assembly 1 to be pivotally connected with the rotating portion 11 via a connecting shaft 26, and the distal end 23 is provided with a limiting structure 25 defining the rotation angle of the handle assembly 1.

The handle assembly 1 may be added with some features to the handle assembly 1 in any of the above embodiments to form a new embodiment, and specifically, the handle assembly 1 includes a rotating portion 11, a gripping portion 12 and a connecting portion 13. The swivel part 11 is rotatably mounted to the body 2 or the extension rod 4 about a connection axis to allow the handle assembly 1 to swivel in a first plane substantially perpendicular to a work surface. A grip portion 12 is connected to the rotating portion 11, the grip portion 12 being configured to be gripped by a user. The connection portion 13 is used to connect the rotation portion 11 and the connection portion 13. In order to make the handle assembly 1 more versatile to fit the needs of different users. The handle assembly 1 comprises a locked state and a rotatable state relative to the body 2 or the extension rod 4. When the handle assembly 1 is in the locked state, the handle assembly 1 is stationary relative to the body 2 or extension pole 4 during use. When the handle assembly 1 is in the rotatable state, the handle assembly 1 can rotate relative to the main body 2 or the extension rod 4 when in use. For example, when a user is cleaning a large space, the user may need to go forward and walk for a period of time and then turn a corner and continue to push the device forward to clean the space in a bow shape, and at the moment, the user only needs to go forward, so that the handle assembly 1 is fixed in a locked state, and the user is labor-saving. Furthermore, some users may be accustomed to the handle being in a stationary state relative to the body 2 or the extension bar 4, and thus the locked state may meet the needs of that part of the user.

Referring to fig. 18-21, in particular, the handle assembly 1 includes a locking structure 9, the locking structure 9 being for retaining the handle assembly 1 in a locked position. Locking structure 9 can be buckle formula, magnetism inhale formula or other structural style, only need guarantee can with handle assembly 1 keep in the locking state can. The locking structure 9 comprises an elastic member 91 and a locking member 92 connected to the elastic member 91, the locking member 92 cooperating with a groove 93 on the main body 2 or the extension rod 4 to hold the handle assembly 1 in the locked position.

Referring to fig. 22-28, on the basis of any of the above embodiments, the rotating portion 11 of the handle assembly is provided with a mounting hole, a connecting shaft 26 is disposed in the mounting hole, and the end of the main body or the extension rod is rotatably connected to the rotating portion 11 through the connecting shaft 26. In order to prevent the handle assembly and the connection structure from shaking as much as possible (the handle assembly is offset to the left and right with respect to the connection structure when in use), a rotation support member 30 needs to be added between the connection shaft 26 and the mounting hole of the rotation part, and the rotation support member 30 is disposed between the mounting hole and the connection shaft so that the rotation part is rotatably supported on the connection shaft.

The rotary part 11 is rotatably supported on the connecting shaft 26 by a rotary support. The rotary supporting members 30 may be bearings or bushings, and the number of the rotary supporting members 30 is two and is respectively disposed at two ends of the connecting shaft 26. When the rotary support 30 is a bearing, the outer circumference of the bearing is fixed in the mounting hole, and the inner wall of the bearing is interference-connected with the connecting shaft. When the rotary support member 30 is a sleeve, the outer circumference of the sleeve is fixedly connected to the inner wall of the mounting hole, and the inner circumference of the sleeve is engaged with the connecting shaft, so that the connecting shaft 26 can freely rotate relative to the sleeve.

Referring to fig. 22-28, the rotatable portion 11 defines an elongated recess into which the distal end 23 of the body 2 or extension rod 4 extends. The recess defines an accommodation space into which a part of the coupling structure 24 extends, the coupling structure 24 and the rotary part 11 being rotatably coupled by a coupling shaft 26. After the connecting shaft 26 is mounted, end caps 95 are provided at both ends of the connecting shaft 26 to shield the connecting shaft. The end cap 95 may also function as a stationary shaft. The connecting shaft 26 is provided with a wire passing hole 96 and a hidden fastener 97, and the hidden fastener 97 can fix the connecting shaft to the connecting structure 24. A control switch 98 is provided on the handle assembly 1 for controlling the surface cleaning apparatus. The wire passage hole 96 facilitates the passage of the wire harness through the connecting structure 24 to be connected to the handle assembly 1, so that the wire harness is not affected even if the handle assembly 1 is rotatable.

Referring to fig. 29-31, the angle between the axis of the body 2 or extension rod 4 and the axis of the grip portion 12 is less than 45 degrees when the handle assembly 1 is in the locked condition. Further, the included angle between the axis of the main body 2 or the extension rod 4 and the axis of the holding part 12 is less than 30 degrees. Even if the handle assembly 1 is in the locked state, the user does not feel much effort when using it.

The present application also discloses a surface cleaning apparatus comprising a handle assembly 1 and a cleaning head as in any of the embodiments described above. The handle assembly is removably mounted to the body or the extension pole. The cleaning head may include a roller brush and drive wheels. The cleaning head may further comprise two mutually parallel roller brushes. The cleaning head may also comprise two mutually parallel roller brushes and a further drive wheel. The handle assembly 1 is rotatable relative to the body 2 or extension pole 4. Referring to fig. 29-31, the handle assembly 1 is rotatable in the r1 direction and the r2 direction. Wherein the angle between the handle and the connecting structure 24 can be defined as c, it can be understood that the angle between the two is the angle between the grip portion 12 and the axial direction of the connecting structure 24. In the use process, the angle c can be changed at any time, so that a user can save more labor in the pushing and pulling process.

When repeatedly pushing and pulling the surface cleaning apparatus for cleaning, if the power assistance (the roller brush grip or the drive wheel drive) of the surface cleaning apparatus is relatively large when advancing, the user is relatively hard when pulling the apparatus backwards. If the power assistance (the roller brush grip or the drive wheel drive) of the surface cleaning apparatus is small when advancing, the user is strenuous when pushing forward. In order to solve the above problems, the present application improves on the rotatable handle assembly 1 to change the power of the cleaning apparatus during the forward or backward pulling process. In particular, a detection device and a controller are added to the surface cleaning apparatus. The detection device is used for detecting the relative position relationship of the handle assembly 1 relative to the main body 2 or the extension rod 4. The controller is used for sending out a control command, and the controller is configured to send out a control command corresponding to the relative position relation. The detection device may be disposed on the handle assembly 1, or may be disposed on the main body 2 or the extension rod 4, or a part of the detection device may be disposed on the handle assembly 1 and a part may be disposed on the main body 2 or the extension rod 4.

With continued reference to fig. 29-31, in one embodiment, the detection means is configured to detect a rotational direction of the handle assembly 1 relative to the body 2 or the extension pole 4, the rotational direction including a first rotational direction r1 and a second rotational direction r2, the rotational direction being switchable between the first rotational direction r1 and the second rotational direction r 2. The controller is configured to issue a control command corresponding to the change of the rotation direction. When the handle rotates from the first rotating direction to the second rotating direction, the operation of a user can be changed from forward pushing to backward pulling, at the moment, the detection device generates a signal, and the controller receives or acquires the signal generated by the detection device and then sends a corresponding control instruction. For example, when the cleaning head is provided with the driving wheel, the rotation direction of the driving wheel may be changed, and when the cleaning head is provided with the roll brush, the rotation speed or the rotation direction of the roll brush may be adjusted to change the grip force or the grip direction of the roll brush. When the cleaning head comprises the double rolling brushes and the rotating directions of the two rolling brushes are opposite, the controller can control the rotating speed of one rolling brush or the two rolling brushes to adjust the force generated by the surface cleaning equipment per se relative to the surface to be cleaned, so that the surface cleaning equipment is more suitable for being controlled by a user. Specifically, the friction force generated by the two rolling brushes relative to the surface to be cleaned is different, so that one rotating speed is greater than the other rotating speed, and the labor is saved in a certain direction.

The change of the rotation direction of the handle assembly 1 may include, but is not limited to, the following several implementations:

1. the forward rotation and the reverse rotation of the handle assembly 1 are detected through a microswitch;

2. detecting the forward rotation and reverse rotation of the handle assembly 1 by using the coding disc through a photoelectric sensor;

3. the forward rotation and reverse rotation of the handle assembly 1 are detected through the rotation angles of the magnetic resistance angle sensor and the magnet, and any position (angle) can be detected;

4. the resistance value of the potentiometer is changed by rotating the handle assembly 1 by using the potentiometer (sliding rheostat) to detect the forward rotation and reverse rotation of the handle assembly 1;

5. detecting the rotation direction of the handle assembly 1 by a hall sensor;

in addition to the above-mentioned methods, other detection methods may be adopted, which are not listed here.

With continued reference to fig. 22-28, the surface cleaning apparatus further comprises detection means for detecting a relative positional relationship between the rotating portion 11 and the connecting shaft 26, the detection means comprising a first element 31 and a second element 32, the first element 31 being disposed on the connecting shaft 26 and the second element 32 being disposed on the rotating portion 11. The first element 31 is a magnetic element that can generate a magnetic field, and the second element 32 is a magnetic sensor for sensing a change in direction of the magnetic field. The magnetic sensor chip calculates and outputs corresponding angle signals (which can be sine and cosine signals, analog angle signals, digital PWM signals, absolute value digital signals and the like) by sensing the rotation change of the direction of the magnetic field (generally working together with a cylindrical radial magnetized magnet). Because the precision requirement to the sensor is higher, if handle assembly takes place to rock about relative connection structure when using (rock about here for the direction of rotation), can influence the precision of detection, probably send the signal by mistake, and then send control command, and this control command probably not user's needs, influence customer experience. Therefore, the rotary support can reduce the left-right shaking of the handle assembly as much as possible so as to ensure the accuracy of the signal sent by the sensor.

Of course, the control instructions may also control the adjustment of other structures. Control command can control the switch of water pump or adjust the play liquid measure of water pump, through the position relation that detects handle components for main part or extension rod, can be more quick and accurate discernment user's intention to adjust surface cleaning equipment through the controller. Because the handle assembly is rotatable, when the position or the motion trend of other parts of the surface cleaning equipment are not changed, the position of the handle assembly is used for prejudging, and a control instruction is sent out in advance, so that the accuracy and the reaction speed can be effectively improved, and the user experience is further improved.

In order to make the control more accurate, a preset area is arranged in the rotating area of the handle assembly 1, and when the rotating direction is changed only in the preset area, the controller is configured to send out a control command corresponding to the change of the rotating direction. When the rotation direction changes outside the preset area, the detection device does not generate a signal or the controller does not send a control command even if the detection device generates a signal.

Referring to fig. 29, when switching from the first rotation direction to the second rotation direction, the controller issues a first control instruction. For example: if the cleaning head comprises two rolling brushes rotating positively and negatively, when the first rotating direction is switched to the second rotating direction, the movement direction of the equipment is changed from forward to backward, and at the moment, the controller controls the rotating speed of the front rolling brush to be reduced or controls the rotating speed of the rear rolling brush to be increased or simultaneously controls the rotating speed of the front rolling brush to be reduced and the rotating speed of the rear rolling brush to be increased according to the signal generated by the detection device. The manner of changing the roller brush is not limited here, but only the force of the device relative to the surface to be cleaned (the force of lifting the roller brush backwards). Therefore, the user can save labor when pulling backwards, and if the backward main force is large, the user does not need to pull backwards, and only needs to hold the handle component 1. When the device is moved backward for a certain distance and needs to be changed from backward pulling to forward pushing, referring to fig. 30, at this time, when the handle assembly 1 is switched from the second rotation direction to the first rotation direction, the controller issues a second control command. Controlling the rotating speed of the front rolling brush to increase or controlling the rotating speed of the rear rolling brush to decrease, or simultaneously controlling the rotating speed of the front rolling brush to increase and the rotating speed of the rear rolling brush to decrease. The manner of changing the roller brush is not limited, and only the force of the device relative to the surface to be cleaned (the force for lifting forward) needs to be changed, so that the user can save labor when pushing forward.

The force of the surface cleaning equipment relative to the ground is controlled through the change of the rotation direction of the handle assembly, the situation that a user drags force for the equipment to change the motion direction of the equipment by manpower when the cleaning equipment is switched to the earliest can be avoided (the dragging force usually gives the user the best experience), whether the motion direction of the cleaning equipment needs to be changed is judged in advance equivalently, when the motion direction needs, the controller directly controls the surface cleaning equipment to generate corresponding assistance force to help the user, the change of the motion direction is realized by the minimum force, and meanwhile, the whole cleaning process is more labor-saving. Furthermore, the control command is sent out through the rotation direction of the handle assembly, so that the control process can be more accurate, and the phenomenon of error control (the user does not want to change the movement direction originally, and the cleaning equipment sends out the control command on the contrary) caused by the difference of user operation is reduced as much as possible.

Referring to fig. 29 and 30, the preset region includes a first preset region and a second preset region. The first predetermined area and the second predetermined area are spaced apart. The first and second predetermined regions may be a range of angles, as shown, the range of the angle a may be the first predetermined region, within which the controller issues a control command according to a signal generated by the detection means if the detection means detects that the rotation direction of the handle assembly 1 is changed. The range of the angle b may be a second preset region within which the controller issues a control command according to a signal generated by the detection means if the detection means detects that the rotation direction of the handle assembly 1 is changed. The values of a and b and the areas where the values are located can be set according to the size of actual equipment and the operation habit of a user, can be set before leaving a factory, and can also be set by the user. The first predetermined area and the second predetermined area are spaced apart. A movement space can be provided for the handle assembly 1, and the situation that when the rotation direction of the handle assembly 1 is changed in the middle area, the controller sends out an instruction to influence the operation of a user is avoided.

Through setting up and predetermineeing the region, only handle assembly's the turn to take place in predetermineeing the region, the controller just sends control command, can effectively adapt to different users' use habit, avoids the emergence of mistake accuse as far as possible simultaneously. Furthermore, two preset areas are arranged at intervals, even if a user turns the handle assembly in the areas at intervals for some reasons, a control signal cannot be sent out, and the control precision is improved.

In another embodiment, the handle assembly 1 comprises a first position and a second position relative to the body 2 or the extension rod 4, and the controller issues a first control command according to a signal generated by the detection device when the handle assembly 1 is in the first position; when the handle assembly 1 is located at the second position, the controller sends out a second control command according to the signal generated by the detection device.

1. the position of the handle assembly 1 is detected through two micro switches;

5. the position of the handle assembly 1 is detected by a hall sensor.

In addition to the above-mentioned methods, other detection methods may be adopted, which are not listed here.

In another embodiment, referring to fig. 30, when the angle between the handle assembly 1 and the main body 2 or the extension rod 4 is smaller than a first predetermined angle, i.e. the angle c is smaller than a certain angle, the controller sends a first control command according to the signal generated by the detecting device. When the angle between the handle assembly 1 and the main body 2 or the extension rod 4 is larger than a second preset angle, namely the angle c is larger than a certain angle, the controller sends a second control instruction according to a signal generated by the detection device.
