Figure 22 (a) is illustrated in the left surface of controlling the toothbrush body 10 under the state that housing 70 cut open by XZ plane to construct.Figure 22 (b) is illustrated in the right flank of controlling the toothbrush body 10 under the state that housing 70 cut open by XZ plane to construct.Figure 23 (a) is illustrated in the positive surface construction of controlling the toothbrush body 10 under the state that housing 70 cut open by YZ plane.Figure 23 (b) is illustrated in the back side of controlling the toothbrush body 10 under the state that housing 70 cut open by YZ plane to construct.

In body shell 11 with control under the state that housing 70 is bonded to each other, around the directive effect of the central axis of electric toothbrush 2, during than the large power of the 4th separating force, controlling combined structure U releasing body shell 11 and controlling the combination between housing 70.On the other hand, body shell 11 and control under housing 70 state separated from one another and controlling side telescoping part UA and outside telescoping part UB between position relationship be the state corresponding to each other and control side telescoping part UC and inner side telescoping part UD between position relationship be under the state corresponding to each other, around the directive effect of the central axis of electric toothbrush 2 during than the large power of the 4th adhesion, control combined structure U by body shell 11 and control housing 70 and be bonded to each other.

Control combined structure U and allow in body shell 11 and control under the state that housing 70 is bonded to each other, control the relative rotation of housing 70 with respect to body shell 11.Control housing 70 and be divided into " on-state " shown in " off-state " shown in " released state " shown in following 3 state: Figure 24 (a) and Figure 24 (b), Figure 25 (a) and Figure 25 (b) and Figure 26 (a) and Figure 26 (b) with respect to the relative rotation status of body shell 11.

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

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

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

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

As shown in Figure 24 (a), make to control operating physical force that housing 70 rotates from from released state to bonding position than the 4th adhesion hour, the moving range around Z axis of controlling side telescoping part UA is limited in the 1st swivelling chute UB1 of shell 20.The 1st swivelling chute UB1 is with suitable to the scope of boundary rib UB3 from the rotation limiting wall UB4 of portion of shell 20.

The rotation UB4 of limiting wall portion with control side telescoping part UA while contacting, to controlling housing 70, to the rotation of the detaching direction with respect to shell 20, limit.Boundary rib UB3 with control side telescoping part UA while contacting, to controlling housing 70, to the rotation of the bonding position with respect to shell 20, limit.

In addition, as shown in Figure 24 (b), make to control operating physical force that housing 70 rotates from from released state to bonding position than the 4th adhesion hour, the moving range around Z axis of controlling side telescoping part UA is limited by inner side telescoping part UD.Inner side telescoping part UD with control side telescoping part UC while contacting, to controlling housing 70, to the rotation of the bonding position with respect to inner shell 30, limit.

As shown in Figure 22 (a) and Figure 22 (b), the 1st swivelling chute UB1 is along the outer surface 30Z ZB opening downwards of inner shell 30.Therefore, be positioned under the state of the 1st swivelling chute UB1 controlling side telescoping part UA, when controlling housing 70 ZB moves downwards with respect to body shell 11, control side telescoping part UA and depart from from the 1st swivelling chute UB1.In addition, make to control side telescoping part UA and the 1st swivelling chute UB1 under the state of Z direction alignment, when controlling housing 70 ZA moves upward with respect to body shell 11, controlling side telescoping part UA and enter the 1st swivelling chute UB1.

Therefore, under released state in Figure 24 (a) and Figure 24 (b), in order to make to control side telescoping part UA, from the 1st swivelling chute UB1, depart from, and make to control housing 70 with respect to body shell 11 downwards ZB move, thereby can make body shell 11 depart from from the opening portion 73 of controlling housing 70.

Conversion from from released state to off-state is described.

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

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

The 4th adhesion is equivalent to cross the necessary operating physical force of boundary rib UB3 and control side telescoping part UC and cross along bonding position the power that telescoping part UD necessary operating physical force in inner side is added together along bonding position controlling 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) and Figure 23 (b), when released state, anode accessory 64 is contactless states with energising accessory 67.The head portion of anode accessory 64 is accompanied by controls the rotation of housing 70 to the bonding position with respect to body shell 11, moves closer to energising accessory 67.In addition, controlling housing 70 while being transformed into off-state with respect 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.

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

As shown in Figure 25 (b), make to control operating physical force that housing 70 rotates from from off-state to bonding position than making operation power hour, inner side telescoping part UD remains on 2 and controls between side telescoping part UC.Thus, control housing 70 to respect to inner shell 30(body shell 11) the rotation of bonding position be limited and maintain off-state.

In addition, as shown in Figure 25 (b), make to control operating physical force that housing 70 rotates from from off-state to detaching direction than the 4th separating force hour, inner side telescoping part UD remains on 2 and controls between side telescoping part UC.Thus, control housing 70 to respect to inner shell 30(body shell 11) the rotation of detaching direction be limited and maintain off-state.

In addition,, as shown in Figure 25 (a), making to control operating physical force that housing 70 rotates from from off-state to detaching direction than the 4th separating force hour, control side telescoping part UA and supported by the boundary rib UB3 of outside telescoping part UB.Thus, control housing 70 to respect to shell 20(body shell 11) the rotation of detaching direction be limited and maintain off-state.

Therefore, under off-state, make to control housing 70 to the operating physical force of bonding position rotation than making operation power hour, and make to control housing 70 to the operating physical force of detaching direction rotation than the 4th separating force hour, control housing 70 and with respect to body shell 11, do not rotate.

Conversion from from off-state to on-state is described.

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

Making operation power is equivalent to make 1 to control side telescoping part UC and cross inner side telescoping part UD necessary operating physical force to bonding position.Therefore, making operation force rate makes body shell 11 and controls rotation status between housing 70 that from released state to off-state, to change necessary the 4th adhesion little, 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 head portion of anode accessory 64 is accompanied by controls the rotation of housing 70 to the bonding position with respect to body shell 11, moves closer to energising accessory 67.And controlling housing 70 while being transformed into on-state with respect to the rotation status of body shell 11 from off-state, anode accessory 64 contacts with energising accessory 67.Therefore, form the closed circuit (with reference to Figure 16) of electronic unit group 60.Therefore, motor 41 rotates.It should be noted that, under off-state, anode accessory 64 is equivalent to " the 1st electrode position " with respect to the position of rotation of energising accessory 67.In addition,, under on-state, anode accessory 64 is equivalent to " the 2nd electrode position " with respect to the position of rotation of energising accessory 67.

Conversion from from off-state to released state is described.

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

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

Body shell 11 and control housing 70 being transformed into the process of off-state from released state or being transformed into from off-state the process of released state, relatively rotates the 1st regulation rotation amount in the direction around Z axis.In addition, body shell 11 and control housing 70 being transformed into the process of on-state from off-state or being transformed into from on-state the process of off-state, relatively rotates the 2nd regulation rotation amount in the direction around Z axis.The 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.

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

As shown in Figure 26 (a), be supported on rotation during the UB5 of limiting wall portion controlling side telescoping part UA, control housing 70 and be limited to the rotation of detaching direction with respect to shell 20.

As shown in Figure 26 (b), making to control operating physical force that housing 70 rotates from from on-state to detaching direction than opening operation power hour, control side telescoping part UC and be supported on inner side telescoping part UD.Thus, controlling housing 70 is limited to the rotation of detaching direction with respect to inner shell 30.

Therefore, under on-state, make to control housing 70 to the operating physical force of detaching direction rotation than opening operation power hour, control housing 70 and with respect to body shell 11, do not rotate.Now, the rotation limiting wall UB5 of portion of shell 20 makes to control side telescoping part UA and cannot rotate to bonding position.Therefore,, under on-state, control housing 70 and to bonding position, do not rotate with respect to body shell 11.

Conversion from from on-state to off-state is described.

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

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

Anode accessory 64(is with reference to Figure 23) under on-state, contact with energising accessory 67.And making body shell 11 and control rotation status between housing 70 while being 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 positive surface construction of anode accessory 64.
