Description

Technical Field

[0001] The present application relates to the technical field of hair cleaning, and particularly relates to a reciprocating motor and a razor. Background Art

[0002] When cutting beards with an electric razor, kinetic energy needs to be provided to the moving blade by a motor to cause a relative shearing motion between the moving blade and the stationary blade. No matter what kind of motor the electric razor uses, the vibration generated by the motor itself during operation is difficult to completely eliminate. Therefore, the vibration generated by the motor will reduce the comfort during holding. In the prior art, for a razor using a reciprocating motor, the moving components of the motor are usually connected to the frame of the motor by elastic components (such as shrapnel) to reduce the vibration of the motor. However, the vibration reduction effect of the above solution is limited, and the user can still significantly feel the vibration when holding the razor.

If the specific posture changes, the directional indications will also change accordingly.

[0040] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present utility model, then the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

Taking "A and / or B" as an example, it includes the A solution, or the B solution, or the solution where A and B are satisfied simultaneously.

[0041] The present utility model provides a reciprocating motor 10, which includes a frame 101, two driving components 109 and two moving components 116. The two driving components 109 and the two moving components 116 are both movably arranged in the frame 101. The two moving components 116 are respectively corresponding to and spaced from the two driving components 109. The two moving components 116 and the two driving components 109 are respectively arranged side by side and spaced apart. Under the electromagnetic action, each moving component 116 and the corresponding driving component 109 reciprocate in opposite directions, and the moving directions of the two moving components 116 are opposite.

[0042] In an embodiment of the present utility model, please refer to Figure 1 and Figure 2 , the reciprocating motor 10 includes a frame 101 for supporting and fixedly connecting, two driving components 109 for generating an electromagnetic field effect after passing an electric current, and two moving components 116 for reciprocating under the electromagnetic effect of the two driving components 109 and transmitting the reciprocating movement. The two driving components 109 and the two moving components 116 are both movably arranged in the frame 101. It should be noted that the movement described here includes but is not limited to elastic suspension movement.

[0043] The two moving components 116 are respectively corresponding to and spaced from the two driving components 109, that is, one moving component 116 is arranged corresponding to one driving component 109. In some embodiments, one moving component 116 and another moving component 116 are arranged side by side and spaced apart in the left and right directions, and one driving component 109 and another driving component 109 are arranged side by side and spaced apart in the left and right directions; under the electromagnetic action, each moving component 116 and the corresponding driving component 109 move in opposite directions, that is, under the electromagnetic action of one moving component 116 and the corresponding driving component 109, when the moving component 116 moves in one direction of the reciprocating movement direction, the driving component 109 corresponding to the moving component 116 moves in the other direction of the reciprocating movement direction; and the moving directions of the two moving components 116 are opposite, that is, when one moving component 116 moves in one direction of the reciprocating movement direction, the other moving component 116 moves in the other direction of the reciprocating movement direction. That is, in this embodiment, the moving directions of the two moving components 116 are opposite, and the moving directions of the two driving components 109 are opposite, forming an asynchronous reciprocating movement of one moving component 116 and the corresponding driving component 109, and the other driving component 109 or moving component 116 and the moving component 116 or driving component 109 move synchronously in reciprocation.

[0044] In this embodiment, the two moving components 116 reciprocate in opposite directions with respect to the corresponding driving components 109 respectively. At the same time, the moving directions of the two moving components 116 are opposite, that is, when moving in opposite directions between the two moving components 116, the two driving components 109 will also move in opposite directions at the same time, and the corresponding moving component 116 and driving component 109 will move in opposite directions. Therefore, the vibrations are mutually cancelled out by the movements of the two moving components 116, the movement between the two driving components 109, and the movements of the corresponding moving component 116 and driving component 109. Therefore, compared with the traditional reciprocating motor, the reciprocating motor 10 of the present utility model can cancel out more vibrations by reciprocating the two driving components 109 and the two moving components 116 in opposite directions, and thus has a better vibration damping effect.

[0045] Further, each driving component 109 includes a base 110 and a driver 111; the reciprocating motor 10 further includes a plurality of elastic suspension structures 115; wherein, the driver 111 is fixedly connected to the base 110; both ends of the base 110 in the reciprocating movement direction of the moving component 116 are movably arranged on the frame 101 through at least one elastic suspension structure 115 respectively.

[0046] In this embodiment, refer to Figure 3 The following specifically describes the two driving components 109. In the two driving components 109, each driving component 109 includes a base 110 for supporting and a driver 111 for generating an electromagnetic effect. The reciprocating motor 10 further includes an elastic suspension structure 115 for elastically suspending the driving component 109. More specifically, the elastic suspension structure 115 is used to elastically suspend the two bases 110 on the frame 101. Specifically, the lower end of the driver 111 is fixedly connected to the base 110, and the connection method includes but is not limited to snap connection. By arranging snaps on the opposite sides of the lower end of the driver 111, the fixed connection is realized by the snap connection between the snaps and the base 110. Both ends of the base 110 in the reciprocating movement direction of the moving component 116 are movably arranged on the frame 101 through at least one elastic suspension structure 115 respectively. In this embodiment, the reciprocating motor 10 includes four elastic suspension structures 115 for elastically suspending the driving component 109. Every two elastic suspension structures 115 elastically suspend one driving component 109, that is, the lower end of each elastic suspension structure 115 is connected to the base 110, and the upper end is connected to the frame 101, so as to elastically suspend the base 110 on the frame 101. In other embodiments, the number of the elastic suspension structures 115 can also be other numbers. To make the forces at both ends of the two driving components 109 in the reciprocating movement direction balanced and reduce vibrations, the number of elastic suspension structures 109 connected to both ends of each driving component 109 in the reciprocating movement direction is the same.

[0047] In this embodiment, the base 110 is elastically suspended on the frame 101 through the elastic suspension structure 115. After the driver 111 is powered on, an electromagnetic effect is generated, causing each driving component 109 and the corresponding moving component 116 to move relative to each other under the electromagnetic effect. Moreover, the reciprocating moving directions of the two driving components 109 are opposite. Compared with the case where the driving components 109 are fixed to the frame 101, part of the vibration is further cancelled out by the reciprocating movement of the two driving components 109.

[0048] Furthermore, the reciprocating motor 10 further includes a plurality of fixing members 114, and each elastic suspension structure 115 is fixedly connected to the frame 101 through the fixing member 114. Specifically, the fixing member 114 can be a rivet. Fixing the elastic suspension structure 115 to the frame 101 by means of a rivet has the advantages of simple installation and firm connection.

[0049] Furthermore, each driver 111 includes a bobbin 112 and a winding 113, and the winding 113 is wound around the bobbin 112; the base 110 extends in a long strip shape along the reciprocating movement direction, and the bobbin 112 is fixedly connected to the middle part in the length direction of the base 110.

[0050] In this embodiment, the driver 111 is specifically described. The driver 111 includes a bobbin 112 and a winding 113. The bobbin 112 is mainly used to connect with the base 110 and wind the winding 113. The base 110 extends in a long strip shape as a whole along the reciprocating movement direction, and the bobbin 112 includes but is not limited to being fixedly connected to the middle part in the length direction of the base 110. The bobbins 112 of the two drivers 111 are arranged in the same direction on the upper wall surface of the base 110. The two bases 110 are arranged side by side in the width direction. And in some embodiments, the two side-by-side bases 110 are at the same height. When the two drivers 111 are respectively arranged on the two bases 110, the two drivers 111 are arranged corresponding to each other. In this embodiment, by arranging the two drivers 111 in the middle of the base 110, compared with the case of arranging them at both ends, when the two drivers 111 are in the middle of the base 110, the entire driving component 109 is more stable when elastically suspended on the frame 101, and the generated vibration is also smaller; the two bases 110 are arranged side by side in the width direction, and the two drivers 111 will also be arranged side by side in this direction. Therefore, the two drivers 111 will be on the same horizontal line, and the vibrations generated by each other will also be on the same horizontal line. Therefore, the vibrations on the same horizontal line are more convenient for cancelling each other, and thus it is more convenient for the vibrations between the two driving components 109 to be cancelled.

[0051] It should be noted that the lower end of each elastic suspension structure 115 is fixedly connected to the base 110, and the upper end is fixedly connected to the frame 101; the connection heights of the elastic suspension structures 115 connected to the two bases 110 with the frame 101 are the same, so that the heights of the two drive components 109 in the frame 101 are the same; the moving component 116 is elastically suspended above the driver 111; and the suspension heights of the two moving components 116 are the same.

[0052] In this embodiment, the base 110 is suspended on the frame 101 through the elastic suspension structure 115, realizing the movement of the drive component 109 in the reciprocating movement direction. The opposite reciprocating movements of the two drive components 109 cancel out part of the vibration; and the elasticity of the elastic suspension structure 115 enables the drive component 109 to quickly reset, improving the working efficiency of the reciprocating motor 10; and the suspension heights of the two moving components 116 are the same. Compared with the situation where the suspension heights of the two moving components 116 are different, when the two moving components 116 move in opposite directions, the vibrations generated by the two moving components 116 are on the same horizontal line, and the vibrations generated by the two moving components 116 will also be on the same horizontal line. The cancellation effect between the two opposite vibrations on the same horizontal line is more obvious. Therefore, the vibration cancellation effect is more obvious when the two moving components 116 move in opposite directions.

[0053] Furthermore, the reciprocating motor 10 further includes a plurality of buffer members 124. Each base 110 is connected to the frame 101 through at least one buffer member 124 at both ends in the reciprocating movement direction; the buffer members 124 connected to the two bases 110 are correspondingly arranged in the side-by-side direction of the two moving components 116.

[0054] In this embodiment, the reciprocating motor 10 further includes a plurality of buffer members 124. The buffer members 124 include but are not limited to springs. Both ends of the base 110 in the reciprocating movement direction are connected to the frame 101 through at least one buffer member 124, specifically as Figure 1 and Figure 2 shown. The buffer members 124 are below the base 110. The buffer members 124 connected to the two bases 110 are correspondingly arranged in the side-by-side direction of the two moving components 116, that is, the buffer members 124 on the same side of the two bases 110 are correspondingly arranged in the side-by-side direction of the moving components 116, that is, at the same height. In this embodiment, by providing the buffer members 124, compared with the situation where no buffer members 124 are provided, the buffer members 124 can further cancel out the vibrations generated by the drive component 109 or the moving component 116.

[0055] Furthermore, each motion component 116 includes a motion seat 117 and a permanent magnet 119. The permanent magnet 119 is fixedly arranged on one side of the motion seat 117 adjacent to the drive component 109; the reciprocating motor 10 further includes a plurality of elastic support structures 125. Both ends of each motion seat 117 along the reciprocating movement direction are respectively connected to both ends of the corresponding drive component 109 through at least one elastic support structure 125; the two drive components 109 have the same height in the frame 101, and the two motion components 116 have the same height in the frame 101.

[0056] In this embodiment, referring to Figure 4 as shown, a specific description is made of the two motion components 116. Each motion component 116 includes a motion seat 117 and a permanent magnet. The permanent magnet is fixedly arranged on the lower side of the motion seat 117. The reciprocating motor 10 further includes four elastic support structures 125 for elastically supporting the motion components 116. Every two elastic support structures 125 elastically support one motion component 116. Each elastic support structure 125 has a first connection end 126 connected to the motion seat 117 and a second connection end 127 connected to the drive component 109, that is, the upper end and the lower end of the elastic support structure 125. Specifically, both ends of the motion seat 117 along the reciprocating movement direction are respectively connected to the first connection ends 126 of the two elastic support structures 125, that is, both ends of the motion seat 117 along the reciprocating movement direction are respectively connected to the upper ends of one elastic support structure 125; the two second connection ends 127 are fixedly connected to the drive component 109, that is, the lower end of the elastic support structure 125 is connected to the drive component 109. More specifically, the lower end of the elastic support structure 125 is connected to the base 110 of the drive component 109. It should be noted that the two first connection ends 126 have the same height, so that the two motion components 116 are at the same height. In other embodiments, the number of the elastic support structures 125 can also be other numbers. To make the forces on both ends of the two motion components 116 along the reciprocating movement direction balanced and reduce vibration, the number of the elastic support structures 125 connected to both ends of each motion component 116 along the reciprocating movement direction is the same.

[0057] In this embodiment, one motion component 116 is suspended above the driver 111 through two elastic support structures 125 respectively, and the first connection ends 126 of the two elastic support structures 125 have the same height, so that the two motion components 116 are at the same height. Furthermore, when the two motion components 116 move in opposite directions along the reciprocating movement direction, the vibration generated is smaller than that when they are not at the same height, and the cancellation effect is more obvious. Also, because the two first connection ends 126 have the same height, the motion component 116 will not generate excessive vibration due to its own inclination during movement.

[0058] Further, each elastic support structure 125 includes two elastic sheets 128 stacked on top of each other and a connecting member 130. Connecting through holes 129 are provided on the two elastic sheets 128, and the connecting member 130 passes through the two connecting through holes 129 to fix the two elastic sheets 128.

[0059] In this embodiment, the elastic support structure 125 is specifically described. Each elastic support structure 125 includes, but is not limited to, two elastic sheets 128 and a connecting member 130 connecting the two elastic sheets 128. Corresponding connecting through holes 129 are respectively provided at the upper ends of the first connecting ends 126 of the two elastic sheets 128. After the connecting member 130 passes through the connecting through holes 129 on the two elastic sheets 128, the two elastic sheets 128 are fixed. It should be noted that the connecting member 130 includes, but is not limited to, a rivet. After the rivet connects the two elastic sheets 128, the two ends of the rivet abut against the end faces of the two elastic sheets 128 facing away from each other.

[0060] In this embodiment, the elastic support structure 125 is formed by stacking two relatively thin elastic sheets 128. Compared with setting one relatively thick elastic sheet 128, the elastic range of the two relatively thin elastic sheets 128 is larger, so the vibration damping effect is more obvious.

[0061] Further, the connecting through holes 129 are provided at one end of the elastic sheet 128 adjacent to the moving seat 117. Avoidance grooves 118 are provided at both ends of the moving seat 117 corresponding to the connecting member 130 along the reciprocating movement direction.

[0062] In this embodiment, avoidance grooves 118 are provided at the positions corresponding to the connecting member 130 at the left and right ends of the moving seat 117. In this embodiment, by providing the avoidance grooves 118, the installation of the elastic suspension structure 115 is facilitated, and at the same time, the volume of the entire reciprocating motor 10 is saved.

[0063] Further, recessed grooves 108 are provided on the inner side walls of the frame 101 opposite to each other in the side-by-side direction of the moving assembly 116 corresponding to the elastic support structure 125. The elastic support structure 125 is partially accommodated in the recessed grooves 108 and can reciprocate in the recessed grooves 108.

[0064] In this embodiment, on the inner side walls of the frame 101 that are opposite to each other in the side-by-side direction of the moving component 116, recessed grooves 108 are correspondingly provided for the elastic support structures 125, that is, the recessed grooves 108 are formed by extending downward from the upper ends of the inner side walls of the frame 101 in the side-by-side direction of the moving component 116, and the recessed grooves 108 do not penetrate to the lower ends, and the extending depth includes but is not limited to the height of the elastic support structures 125. On the side of the elastic support structure 125 close to the recessed groove 108, a part is accommodated in the recessed groove 108 and can reciprocate within the recessed groove 108. In this embodiment, by providing the recessed grooves 108, compared with the case where the recessed grooves 108 are not provided, an activity space for the elastic support structure 125 to move can be provided, thereby reducing the volume of the reciprocating motor 10.

[0065] Further, the frame 101 includes a first main body 102, a second main body 103, and two connecting beams 104; wherein, the first main body 102 and the second main body 103 are arranged opposite to each other, and the two ends of the two connecting beams 104 are respectively connected to the ends of the same side of the first main body 102 and the second main body 103, and the multiple elastic suspension structures 115 connected to the two driving components 109 are respectively fixed on the opposite wall surfaces of the two connecting beams 104, and the two driving components 109 are arranged side by side in the length direction of the connecting beams 104.

[0066] In this embodiment, referring to Figure 5 As shown, a specific description of the frame 101 is given. The frame 101 specifically includes a first main body 102, a second main body 103, and two connecting beams 104 connecting the first main body 102 and the second main body 103.

[0075] In this embodiment, the housing 131 includes a main housing 15 and an end cap 14, and the shaver 1 further includes a fastener 12 that fixedly connects the reciprocating motor 10 to the end cap 14. A cavity is provided in the main housing 15, and one side of the cavity facing the end cap 14 has an opening. The frame 101 of the reciprocating motor 10 is fixedly connected to the end cap 14. When the end cap 14 is provided at the opening of the cavity, the reciprocating motor 10 is inside the cavity, and the end cap 14 is fixedly connected to the main housing 15. It should be noted that a first mounting hole 105 is provided on the frame 101, and a second mounting hole 106 corresponding to the first mounting hole 105 is provided on the side of the end cap 14 facing the frame. The fastener passes through the first mounting hole 105 and the second mounting hole 106 and fixedly connects the frame 101 and the end cap 14.

[0076] In this embodiment, by integrally arranging the reciprocating motor 10 on the end cap 14, after the vibrations offset by the two moving components 116 of the reciprocating motor 10, the remaining vibrations will be transmitted to the end cap 14, and then away from the holding part of the shaver 1, so that the user feels less vibration when holding the shaver 1.

[0077] In this embodiment, the first transmission assembly 132 includes a first fixed seat 120 and a plurality of first transmission rods 121, and the second transmission assembly 133 includes a second fixed seat 122 and a plurality of second transmission rods 123. Each first transmission rod 121 and each second transmission rod 123 are connected to a cutter head 13. The number of the first transmission rods 121 is less than that of the second transmission rods 123; the weight of the first fixed seat 120 is greater than that of the second fixed seat 122.

[0078] In this embodiment, the first transmission assembly 132 and the second transmission assembly 133 are further specifically described. The first transmission assembly 132 includes a first fixed seat 120 and a plurality of first transmission rods 121, and the second transmission assembly 133 includes a second fixed seat 122 and a plurality of second transmission rods 123. Each first transmission rod 121 and each second transmission rod 123 are respectively connected to a cutter head 13. In this embodiment, the number of the first transmission rods 121 is less than that of the second transmission rods 123, and the weight of the first fixed seat 120 is greater than that of the second fixed seat 122.

[0079] The first fixed seat 120 and the second fixed seat 122 are respectively arranged on the side of the moving seat 117 away from the driving assembly 109, that is, the first fixed seat 120 and the second fixed seat 122 are respectively arranged on the upper end surface of the moving seat 117. It should be noted that the connection method of the first fixed seat 120 and the second fixed seat 122 respectively with the two moving assemblies 116 includes but is not limited to connection by screws or bolts. A plurality of first transmission rods 121 are arranged on the first fixed seat 120, and a plurality of second transmission rods 123 are arranged on the second fixed seat 122. The functions of the first transmission rod 121 and the second transmission rod 123 are that the first transmission rod 121 and the second transmission rod 123 are respectively connected to a cutter head 13. When the moving assembly 116 reciprocates, the cutter head 13 is reciprocated by the first transmission rod 121 and the second transmission rod 123 to achieve shearing. It should be noted that there is one first transmission rod 121 and two second transmission rods 123, and the weight of the first fixed seat 120 is greater than the weight of the second fixed seat 122.

[0080] In this embodiment, different numbers of first transmission rods 121 and second transmission rods 123 are driven by two motion components 116, so the weight of the reciprocating motor 10 on one side of the second transmission rod 123 is greater than the weight on one side of the first transmission rod 121. In order to correct this imbalance, the weight difference between the first fixed base 120 and the second fixed base 122 is compensated to improve the overall stability of the reciprocating motor 10 and thereby reduce vibration.
