More specifically, the tensioning mechanism 50 is electrically connected to the control module, and when the transmission belt is in a slack state, the tensioning mechanism 50 can act under the instruction of the control module, so as to tension the transmission belt, thereby significantly reducing the noise generated during the operation of the transmission belt, and thus significantly reducing the overall operating noise of the noise reduction shaver.
The noise reduction shaver provided by the embodiment of the present application is further described as follows: according to the noise reduction shaver provided by the embodiment of the application, the driving mechanism 11 is arranged in the handle 10, and the driving mechanism 11 can provide the belt transmission mechanism 30 to drive the rotary blade 21 in the cutter head 20 to rotate, so that the shaving function of the noise reduction shaver is realized. The noise reduction shaver provided by the embodiment of the application is provided with the monitoring module 40, so that the monitoring module 40 can acquire the pressure signal on the surface of the transmission belt of the belt transmission mechanism 30 in real time, the control module judges whether the transmission belt is in a loose state according to the pressure signal returned by the monitoring module 40, and when the control module judges that the transmission belt is in the loose state, the tensioning mechanism 50 can tension the transmission belt according to the instruction of the control module. Therefore, in the process of long-term use of the transmission belt, the effective correction of the transmission belt relaxation phenomenon can be realized through the synergistic effect of the monitoring module 40, the control module and the tensioning mechanism 50, so that the shaver has better noise reduction performance in the process of long-term use.

Specifically, when the belt transmission mechanism 30 works, the driving wheel 31 of the belt transmission mechanism is sleeved on the driving shaft of the driving mechanism 11, and further rotates along with the driving shaft when the driving shaft rotates, and the driving wheel 31 and the first belt wheel 32 are connected through the first transmission belt 36, so that the driving wheel 31 can efficiently transmit power to the first belt wheel 32 through the first transmission belt 36, the first belt wheel 32 can transmit power to the second belt wheel 33 through the rotating shaft 34, the second belt wheel 33 can transmit power to each driven wheel 35 through the second transmission belt 37, and the driven wheel 35 can be connected with the rotary blade 21 through the connecting piece, so as to drive the rotary blade 21 to rotate. In this way, power transmission between the driving mechanism 11 and the rotary blade 21 is mainly realized through the first transmission belt 36 and the second transmission belt 37 of the belt transmission mechanism 30, so that the efficiency of power transmission between the driving mechanism 11 and the rotary blade 21 is also improved, and further, the rotating speed of the rotary blade 21 is also ensured, thereby improving the shaving efficiency of the noise reduction shaver.
In other embodiments of the present application, the monitoring module 40 can also obtain the pressure signal of the surface of the second transmission belt 37 simultaneously or separately based on the pressure signal of the surface of the first transmission belt 36, so that the tensioning mechanism 50 is used to tension the second transmission belt 37 under the control of the control module when the second transmission belt 37 is in a slack state. Therefore, real-time synchronous monitoring and tensioning of the slack states of the first transmission belt 36 and the second transmission belt 37 are realized, so that the running noise reduction performance of the belt transmission mechanism 30 is further improved, and the overall noise reduction performance of the noise reduction shaver is further improved.
In other embodiments of the present application, as shown in fig. 2, the monitoring module 40 includes a first pressure sensor 41 electrically connected to the control module, and the first pressure sensor 41 is disposed in the handle 10 and abuts against the surface of the first transmission belt 36 to obtain a pressure signal of the first transmission belt 36.
Specifically, by abutting the first pressure sensor 41 of the monitoring module 40 against the surface of the first transmission belt 36, when the first transmission belt 36 runs, the first pressure sensor 41, which forms a static friction state with the surface of the first transmission belt 36, can acquire the tension change information of the surface of the first transmission belt 36 in real time, so as to simply and reliably realize continuous and real-time acquisition of the pressure change signal of the surface of the first transmission belt 36.
Alternatively, the first pressure sensor 41 may be a micro piezoresistive pressure sensor, which may be an integrated silicon chip sensor manufactured by using micro-mechanical electronic processing technology, so that on one hand, the sensing accuracy of the first pressure sensor 41 can be ensured, and on the other hand, the assembly volume of the first pressure sensor 41 can also be effectively controlled, thereby avoiding the monitoring module 40 from occupying the limited assembly space in the handle 10.
Alternatively, the contact end of the first pressure sensor 41 and the surface of the first transmission belt 36 may be sleeved with an anti-wear sheath or covered with an anti-wear film, so that the contact end of the first pressure sensor 41 can be effectively protected, thereby improving the reliability of the first pressure sensor 41 in long-term use.
In other embodiments of the present application, as shown in the figure, the control module is configured to obtain the pressure signal transmitted back by the first pressure sensor 41, compare the pressure signal with a preset threshold value, and determine that the first transmission belt 36 is in a slack state when the pressure signal is smaller than the threshold value.
Specifically, when the control module receives the pressure signal transmitted back by the first pressure sensor 41, the pressure signal may be compared with a preset threshold, in this embodiment, the threshold is a preset standard pressure value, and when the pressure signal is smaller than the standard pressure value, it indicates that the surface tension of the first transmission belt 36 is reduced, and the first transmission belt 36 is loosened, so that the control module may determine that the first transmission belt 36 is in a loosened state.
For example, the pressure signal transmitted by the first pressure sensor 41 is D1 value, the preset standard pressure value is D value, and when at least two-thirds of the n (n is an integer greater than or equal to 3) D1 values transmitted by the first pressure sensor 41 are smaller than D value within a preset time, it can be determined that the first transmission belt 36 is in a slack state. Therefore, the reliability of judging whether the first transmission belt 36 is in a loose state or not by the control module is improved, and the influence of accidental factors on the judgment result is avoided.
In other embodiments of the present application, as shown in fig. 3, the monitoring module 40 further includes a second pressure sensor 42 electrically connected to the control module, and the second pressure sensor 42 is disposed in the cutter head 20 and abuts against the surface of the second transmission belt 37 to obtain a pressure signal of the second transmission belt 37.
Specifically, by abutting the second pressure sensor 42 of the monitoring module 40 against the surface of the second transmission belt 37, when the second transmission belt 37 runs, the second pressure sensor 42 forming a static friction state with the surface of the second transmission belt 37 can acquire the tension change information of the surface of the second transmission belt 37 in real time, so that the continuous and real-time acquisition of the pressure change signal of the surface of the second transmission belt 37 can be simply and reliably realized.
Alternatively, the second pressure sensor 42 may also be a micro-piezoresistive pressure sensor, which may be an integrated silicon chip sensor manufactured by using micro-machining electronic technology, so that on one hand, the sensing accuracy of the second pressure sensor 42 can be ensured, and on the other hand, the assembly volume of the second pressure sensor 42 can also be effectively controlled, thereby avoiding the monitoring module 40 from occupying the limited assembly space in the tool bit 20.
Optionally, the contact end of the second pressure sensor 42 and the surface of the second transmission belt 37 may also be sleeved with an anti-wear sheath or covered with an anti-wear film, so that the contact end of the second pressure sensor 42 can be effectively protected, thereby improving the reliability of the second pressure sensor 42 in long-term use.
In other embodiments of the present application, the control module is configured to obtain the pressure signal transmitted back by the second pressure sensor 42, compare the pressure signal with a preset threshold, and determine that the second transmission belt 37 is in a slack state when the pressure signal is smaller than the threshold.
Similarly, when the control module receives the pressure signal transmitted back by the second pressure sensor 42, the pressure signal may be compared with a preset threshold, in this embodiment, the threshold is a preset standard pressure value, and when the pressure signal is smaller than the standard pressure value, it indicates that the surface tension of the second transmission belt 37 is reduced, and the second transmission belt 37 is loosened, so that the control module may determine that the second transmission belt 37 is in a loosened state.
For example, the pressure signal transmitted by the second pressure sensor 42 is D1 value, the preset standard pressure value is D value, and when at least two-thirds of the n D1 values transmitted by the second pressure sensor 42 are smaller than D value within a preset time, it can be determined that the second transmission belt 37 is in a slack state. Therefore, the reliability of judging whether the second transmission belt 37 is in a loose state or not by the control module is improved, and the influence of accidental factors on the judgment result is avoided.
In other embodiments of the present application, as shown in fig. 1, the tensioning mechanism 50 includes a first micro-motion device 51 and a first guiding mechanism, the first guiding mechanism is disposed on the handle 10 along a connecting line between an axis of the rotating shaft 34 and a center of the driving wheel 31, the rotating shaft 34 is rotatably disposed on the first guiding mechanism, the first micro-motion device 51 is disposed on the handle 10 and electrically connected to the control module, a driving end of the first micro-motion device 51 is connected to the rotating shaft 34 and is configured to push the rotating shaft 34 to micro-move along a radial direction of the driving wheel 31 toward a direction away from the driving wheel 31 when the first driving belt 36 is in a slack state.
Specifically, when the tensioning mechanism 50 tensions the first transmission belt 36, the first micro-motion device 51 applies an urging force to the rotating shaft 34 under the control of the control module, so that the rotating shaft 34 is micro-moved under the guidance of the first guide mechanism toward the direction away from the driving wheel 31, so that the distance between the first pulley 32 and the driving wheel 31 is increased under the driving of the rotating shaft 34, and thus, the effective tensioning of the first pulley wound between the first pulley 32 and the driving wheel 31 is realized.
Since the movement of the rotating shaft 34 is realized by the micro-motion action of the first micro-motion device 51, the movement amount is small, and therefore, the assembly position of the second belt wheel 33 connected with the rotating shaft and the matching relation of the second belt wheel and the second transmission belt 37 are not obviously influenced, and the use reliability of the noise reduction shaver is ensured.
