Holding combined structure U holds the relative rotation of housing 70 relative to body shell 11 under allowing the state be bonded to each other in body shell 11 and holding housing 70.Hold housing 70 and be divided into following 3 states relative to the relative rotation status of body shell 11: " off-state " shown in " released state " shown in Figure 24 (a) He Figure 24 (b), Figure 25 (a) He Figure 25 (b) and " on-state " shown in Figure 26 (a) He Figure 26 (b).

When being in released state between holding housing 70 and body shell 11, holding housing 70 can be separated from body shell 11.When being in off-state between holding housing 70 and body shell 11, the power supply of electric toothbrush 2 is disconnected.When being in on-state between holding housing 70 and body shell 11, the power supply of electric toothbrush 2 is switched on.In the present embodiment, under holding housing 70 is incorporated into the bonding state of body shell 11, on-state and off-state can be switched.

When holding housing 70 and rotating along the counter clockwise direction Figure 24 (a) relative to body shell 11 from released state, holding housing 70 and body shell 11 are changed from released state to bonding state.Below, this direction of rotation is called " bonding position ".In the present embodiment, when holding housing 70 and rotating to bonding position from released state, holding housing 70 and body shell 11 are changed to the bonding state corresponding to off-state (Figure 25 (a) and Figure 25 (b)) at first, then change to the bonding state corresponding to on-state (Figure 26 (a) and Figure 26 (b)).That is, hold housing 70 relative to body shell 11, rotate along bonding position according to the order of separation point position, power OFF position and power position.On the other hand, when holding housing 70 and rotating along the clockwise direction Figure 25 (a) relative to body shell 11 from off-state, holding housing 70 and body shell 11 are changed from bonding state to released state.Below, this direction of rotation is called " detaching direction ".It should be noted that, when being in off-state, hold housing 70 and be equivalent to " the 1st position of rotation " relative to the relative position of rotation of body shell 11.In addition, when being in on-state, hold housing 70 and be equivalent to " the 2nd position of rotation " relative to the relative position of rotation of body shell 11.

With reference to Figure 22 ~ Figure 24, describe released state in detail.

The profile construction of under the released state of Figure 24 (a) expression between body shell 11 and holding housing 70, in Figure 22 (a) and Figure 22 (b) D22A-D22A plane.The profile construction of under the released state of Figure 24 (b) expression between body shell 11 and holding housing 70, in Figure 22 (a) and Figure 22 (b) D22B-D22B plane.

As shown in Figure 24 (a), when the operating physical force making holding housing 70 rotate from released state to bonding position is less than the 4th adhesion, the moving range around Z axis holding side telescoping part UA is limited in the 1st swivelling chute UB1 of shell 20.1st swivelling chute UB1 is with suitable to the scope of boundary rib UB3 from the rotating limiting walls portion UB4 of shell 20.

Rotating limiting walls portion UB4, when contacting with holding side telescoping part UA, limits holding the rotation of housing 70 to the detaching direction relative to shell 20.Boundary rib UB3, when contacting with holding side telescoping part UA, limits holding the rotation of housing 70 to the bonding position relative to shell 20.

In addition, as shown in Figure 24 (b), when the operating physical force making holding housing 70 rotate from released state to bonding position is less than the 4th adhesion, hold the moving range around Z axis of side telescoping part UA limit by inner side telescoping part UD.Inner side telescoping part UD, when contacting with holding side telescoping part UC, limits holding the rotation of housing 70 to the bonding position relative to inner shell 30.

As shown in Figure 22 (a) He Figure 22 (b), the 1st swivelling chute UB1 is along the outer surface 30Z ZB opening downwards of inner shell 30.Therefore, under the state that holding side telescoping part UA is positioned at the 1st swivelling chute UB1, when ZB moves holding housing 70 downwards relative to body shell 11, hold side telescoping part UA and depart from from the 1st swivelling chute UB1.In addition, under the state making holding side telescoping part UA and the 1st swivelling chute UB1 align in Z-direction, when holding housing 70 ZA moving upward relative to body shell 11, hold side telescoping part UA and enter the 1st swivelling chute UB1.

Therefore, under released state in Figure 24 (a) and Figure 24 (b), depart from from the 1st swivelling chute UB1 to make holding side telescoping part UA, and make holding housing 70 relative to body shell 11 downwards ZB move, thus body shell 11 can be made to depart from from holding the opening portion 73 of housing 70.

Be described from released state to the conversion of off-state.

Under released state, when holding housing 70 and rotating to bonding position relative to body shell 11, as shown in Figure 24 (a), hold side telescoping part UA and contact with boundary rib UB3.

Under the released state shown in Figure 24 (a) He Figure 24 (b), when utilizing the operating physical force larger than the 4th adhesion to make holding housing 70 rotate to bonding position relative to body shell 11, hold side telescoping part UA and cross boundary rib UB3 along bonding position, and hold side telescoping part UC and cross inner side telescoping part UD along bonding position.Thus, hold the relative rotation status of housing 70 relative to body shell 11, to the off-state conversion such as shown in Figure 25 (a) He Figure 25 (b).

4th adhesion is equivalent to cross the necessary operating physical force of boundary rib UB3 along bonding position and hold side telescoping part UC and cross along bonding position the power that inner side telescoping part UD necessary operating physical force is added together by holding side telescoping part UA.It should be noted that, the 4th adhesion is an example of " the 2nd operating physical force ".

As shown in Figure 23 (a) He Figure 23 (b), when released state, anode accessory 64 is contactless states with energising accessory 67.The tip portion of anode accessory 64, along with holding the rotation of housing 70 to the bonding position relative to body shell 11, moves closer to energising accessory 67.In addition, when holding housing 70 and being transformed into off-state relative to the rotation status of body shell 11 from released state, anode accessory 64 is also contactless state with energising accessory 67.

With reference to Figure 25, describe off-state in detail.

The profile construction of under the off-state of Figure 25 (a) expression between body shell 11 and holding housing 70, in Figure 22 (a) and Figure 22 (b) D22A-D22A plane.The profile construction of under the off-state of Figure 25 (b) expression between body shell 11 and holding housing 70, in Figure 22 (a) and Figure 22 (b) D22B-D22B plane.

As shown in Figure 25 (b), when the operating physical force making holding housing 70 rotate from off-state to bonding position is less than making operation power, inner side telescoping part UD remains on 2 and holds between the telescoping part UC of side.Thus, hold housing 70 be limited to the rotation of the bonding position relative to inner shell 30 (body shell 11) and maintain off-state.

In addition, as shown in Figure 25 (b), when the operating physical force making holding housing 70 rotate from off-state to detaching direction is less than the 4th separating force, inner side telescoping part UD remains on 2 and holds between the telescoping part UC of side.Thus, hold housing 70 be limited to the rotation of the detaching direction relative to inner shell 30 (body shell 11) and maintain off-state.

In addition, as shown in Figure 25 (a), when the operating physical force making holding housing 70 rotate from off-state to detaching direction is less than the 4th separating force, hold side telescoping part UA support by the boundary rib UB3 of outside telescoping part UB.Thus, hold housing 70 be limited to the rotation of the detaching direction relative to shell 20 (body shell 11) and maintain off-state.

Therefore, in the off state, when the operating physical force making holding housing 70 rotate to bonding position is less than making operation power, and when the operating physical force making holding housing 70 rotate to detaching direction is less than the 4th separating force, holds housing 70 and do not rotate relative to body shell 11.

Be described from off-state to the conversion of on-state.

Under the off-state shown in Figure 25 (a) He Figure 25 (b), when utilizing the operating physical force larger than making operation power to make holding housing 70 rotate to bonding position relative to body shell 11, holding side telescoping part UC and crossing inner side telescoping part UD along bonding position.Thus, hold the relative rotation status of housing 70 relative to body shell 11, to the on-state conversion such as shown in Figure 26 (a) He Figure 26 (b).

Making operation power is equivalent to make 1 to hold side telescoping part UC and crosses the necessary operating physical force of inner side telescoping part UD to bonding position.Therefore, it is little that making operation force rate makes body shell 11 and the rotation status held between housing 70 change necessary 4th adhesion from released state to off-state, and it should be noted that, making operation power is equivalent to " the 1st operating physical force ".

As shown in figure 23, when off-state, anode accessory 64 is contactless states with energising accessory 67.The tip portion of anode accessory 64, along with holding the rotation of housing 70 to the bonding position relative to body shell 11, moves closer to energising accessory 67.And when holding housing 70 and being transformed into on-state relative to the rotation status of body shell 11 from off-state, anode accessory 64 contacts with energising accessory 67.Therefore, the closed circuit (with reference to Figure 16) of electronic unit group 60 is formed.Therefore, motor 41 rotates.It should be noted that, in the off state, anode accessory 64 is equivalent to " the 1st electrode position " relative to the position of rotation of energising accessory 67.In addition, in an on state, anode accessory 64 is equivalent to " the 2nd electrode position " relative to the position of rotation of energising accessory 67.

Be described from off-state to the conversion of released state.

Under the off-state shown in Figure 25 (a) He Figure 25 (b), when utilizing the operating physical force larger than the 4th separating force to make holding housing 70 rotate to detaching direction relative to body shell 11, hold side telescoping part UA and cross boundary rib UB3 along detaching direction, and hold side telescoping part UC crosses inner shell 30 inner side telescoping part UD along detaching direction.Thus, hold the relative rotation status of housing 70 relative to body shell 11, to the released state conversion such as shown in Figure 24 (a) He Figure 24 (b).

4th separating force is equivalent to cross the necessary operating physical force of boundary rib UB3 and 1 along detaching direction and hold side telescoping part UC by holding side telescoping part UA and cross along detaching direction the power that telescoping part UD necessary operating physical force in inner side is added together.In the present embodiment, as shown in Figure 24 (b), inner side telescoping part UD has: the 1st inclined-plane, and it, when holding housing 70 and rotating to bonding position, holds side telescoping part UC abut with 1; And the 2nd inclined-plane, it is when holding housing 70 and rotating to detaching direction, holds side telescoping part UC abut with 1.2nd inclined-plane has the angle of inclination larger than the 1st inclined-plane.Therefore, make 1 to hold side telescoping part UC to cross inner side telescoping part UD necessary revolving force larger than the necessary revolving force of telescoping part UD inside making 1 holding side telescoping part UC when holding housing 70 and rotating to bonding position and crossing when holding housing 70 and rotating to detaching direction.Therefore, the 4th separating force is larger than the 4th adhesion.But, the 4th separating force also can be made equal with the 4th adhesion.It should be noted that, the 4th separating force is an example of " the 2nd operating physical force ".

Body shell 11 and holding housing 70 are being transformed into the process of off-state or are being transformed into the process of released state from off-state from released state, relatively rotate the 1st regulation rotation amount in the direction around Z axis.In addition, body shell 11 and holding housing 70 are being transformed into the process of on-state or are being transformed into the process of off-state from on-state from off-state, relatively rotate the 2nd regulation rotation amount in the direction around Z axis.2nd regulation rotation amount is less than the 1st regulation rotation amount.It should be noted that, the 1st regulation rotation amount is equivalent to " the 2nd operational ton ".In addition, the 2nd regulation rotation amount is equivalent to " the 1st operational ton ".

With reference to Figure 26 (a) and Figure 26 (b), describe on-state in detail.

The profile construction of under the on-state of Figure 26 (a) expression between body shell 11 and holding housing 70, in Figure 22 (a) and Figure 22 (b) D22A-D22A plane.The profile construction of under the on-state of Figure 26 (b) expression between body shell 11 and holding housing 70, in Figure 22 (a) and Figure 22 (b) D22B-D22B plane.

As shown in Figure 26 (a), when holding side telescoping part UA and being supported on rotating limiting walls portion UB5, hold housing 70 and be limited relative to the rotation of shell 20 to detaching direction.

As shown in Figure 26 (b), when the operating physical force making holding housing 70 rotate from on-state to detaching direction is less than opening operation power, holds side telescoping part UC and be supported on inner side telescoping part UD.Thus, hold housing 70 to be limited relative to the rotation of inner shell 30 to detaching direction.

Therefore, in an on state, when the operating physical force making holding housing 70 rotate to detaching direction is less than opening operation power, holds housing 70 and do not rotate relative to body shell 11.Now, the rotating limiting walls portion UB5 of shell 20 makes holding side telescoping part UA cannot rotate to bonding position.Therefore, in an on state, hold housing 70 not rotate to bonding position relative to body shell 11.

Be described from on-state to the conversion of off-state.

Under the on-state shown in Figure 26 (a) He Figure 26 (b), when utilizing the operating physical force larger than opening operation power to make holding housing 70 rotate to detaching direction relative to body shell 11, holding side telescoping part UC and crossing inner side telescoping part UD along detaching direction.Thus, hold the relative rotation status of housing 70 relative to body shell 11, to the off-state conversion such as shown in Figure 25 (a) He Figure 25 (b).

Opening operation power is equivalent to make 1 to hold side telescoping part UC and crosses the necessary operating physical force of inner side telescoping part UD along detaching direction.As described above, hold housing 70 when detaching direction rotates, make 1 to hold side telescoping part UC to cross inner side telescoping part UD necessary revolving force larger than the necessary revolving force of telescoping part UD inside holding housing 70 and make when bonding position rotates 1 holding side telescoping part UC and crossing.Therefore, to make body shell 11 and the rotation status held between housing 70 change necessary making operation power from off-state to on-state large for opening operation force rate.But opening operation power and making operation power also can be set as the same large.It should be noted that, opening operation power is an example of " the 1st operating physical force ".

Anode accessory 64 (with reference to Figure 23) contacts with energising accessory 67 in an on state.And when making body shell 11 and the rotation status held between housing 70 be converted to off-state from on-state, anode accessory 64 leaves energising accessory 67.Thus, the closed circuit of electronic unit group 60 disconnects (with reference to Figure 16).Therefore, the rotation of motor 41 stops.

With reference to Figure 27, the shape of anode accessory 64 is described.Figure 27 (a) represents the end face structure of anode accessory 64.Figure 27 (b) represents the left surface structure of anode accessory 64.Figure 27 (c) represents the frontal construction of anode accessory 64.
