[0031] Next, the embodiments of this specification are described in detail.

[0032] In shaving equipment, two or more blade heads can be used to increase the contact area during use and improve shaving efficiency and user experience. For dual-blade head shaving equipment, if a single motor is used, after a period of use, the motor is more likely to produce mechanical fatigue, resulting in insufficient power, noise and other phenomena, which will reduce the service life of the product. Therefore, in order to improve this situation, dual-blade head shaving equipment can be driven by dual motors, with each motor driving a blade head respectively, which can increase the service life of the product while ensuring that each blade head has sufficient driving power. However, in the case of dual motors, due to the small overall size of the shaving equipment, the two motors may be installed in close positions, interfering with each other and affecting their normal operation.

[0033] In view of this, this embodiment provides a shaving device 100, referring to Figure 1-Figure 2As shown, the shaving device 100 includes a housing 110, a motor 120 and a cutter head assembly 130. A hollow portion 111 is provided in the middle of the housing 110, and the hollow portion 111 divides the left and right sides of the housing 110 into a left chamber 112 and a right chamber 113, and forms a housing upper portion 114 and a housing lower portion 115. The space of the housing upper portion 114 is connected to the left chamber 112 and the right chamber 113, and the space of the housing lower portion 115 is also connected to the left chamber 112 and the right chamber 113. The chambers 113 are all connected; the number of the motors 120 is two, including a first motor 121 and a second motor 122, the first motor 121 is arranged in the left chamber 112 in the shell 110, and the right shell 110 is arranged in the right chamber 113 in the shell 110; the cutter head assembly 130 is connected to the upper part 114 of the shell, and the cutter head assembly 130 includes two cutter heads, and the cutter heads correspond to the motors 120 one by one, and each cutter head works under the drive of the corresponding motor 120.

[0034] In this embodiment, the interior of the shell 110 is a hollow structure, and the internal space surrounded by the shell 110 is an approximately closed space. The various parts of the shell 110 are interconnected, and a hollow structure, namely a hollow part 111, is set in the middle of the shell 110. The shell 110 surrounds the hollow part 111 to form a similar ring-shaped structure. Due to the setting of the hollow part 111, the internal space of the shell 110 can be roughly divided into an upper shell 114, a lower shell 115, and a left side and a right side. In this way, the relative directions of structures that are not suitable for adjacent settings can be set to avoid interference or mutual influence. For example, in this embodiment, in order to avoid mutual disturbance between the two motors 120, the two motors 120 are respectively set on the left and right sides of the shell 110, the first motor 121 is set in the left chamber 112 of the shell 110, and the second motor 122 is set in the right chamber 113, so that they keep a distance.

[0035] At the same time, the shape design of the housing 110 in this embodiment can also make the shell of the product more beautiful on the basis of dividing the two motors 120. The shape of the hollow part 111 on the housing 110 can be changed at will, and it can be designed into different geometric shapes such as circle, triangle, rectangle, star, etc. in accordance with the appearance of the product. Preferably, in this embodiment, in order to meet the holding requirements of the shaving device 100 when in use, the hollow part 111 is set to be circular, that is, there is a circular through hole in the middle of the housing 110, and the hole can be further designed to have a smooth transition, so that the user can place the finger in the hollow part 111 when using it, which makes it more convenient to hold while the appearance is beautiful.

[0036] The shaving device 100 includes two cutter heads, namely a first cutter head 131 and a second cutter head 132. The first cutter head 131 corresponds to the first motor 121 and is driven to work by the first motor 121; while the second cutter head 132 corresponds to the second motor 122 and is driven to work by the second motor 122. Therefore, for the two cutter heads, two motors 120 are provided, and each motor 120 drives only one cutter head to work, which can reduce the working pressure of the motor 120, reduce wear, etc., and thus increase the service life of the motor 120 and further extend the service life of the shaving device 100.

[0037] Further, such as Figure 3 The shaving device 100 further includes a touch control component 140 , and the touch control component 140 includes a conductive ring 141 disposed at the edge of the hollow portion 111 , and the conductive ring 141 is used to receive an electrical signal generated when a user touches the conductive ring 141 .

[0038] refer to Figure 1-Figure 3 , if necessary, you can refer to Figure 2 and Figure 4 The touch component 140 includes a conductive ring 141 arranged along the edge of the hollow portion 111. In the present embodiment, the conductive ring 141 is arranged along the circumference of the hollow portion 111, and further, the conductive ring 141 is arranged on the outer surface of the hollow portion 111 and serves as a partial outer surface of the shell 110.

[0039] The conductive ring 141 is exposed on the housing 110 of the shaving device 100. When a user uses the shaving device 100, he can directly touch the conductive ring 141, so that the conductive ring 141 can receive the electrical signal generated by the user touching the conductive ring 141, and the start and end of the operation of the shaving device 100 can be controlled by the electrical signal.

[0040] Preferably, the housing 110 in this embodiment can be set to be annular, that is, the outer peripheral side is also circular, and the hollow part 111 in the middle is also circular, so that when the user holds it, it is convenient to put the finger, especially the thumb, into the hollow part 111. At this time, since the conductive ring 141 is set at the edge of the hollow part 111, when the user holds it, the thumb can be easily inserted into the hollow part 111 and touch the conductive ring 141, and the operation of the shaving device 100 can be controlled by touching the conductive ring 141. Therefore, the setting of the hollow part 111 and the conductive ring 141 makes it convenient for the user to hold it, and the operation of the shaving device 100 can be controlled by touch when holding it, so it is more convenient to use and can improve the user's experience.

[0041] The shaving device 100 further includes a control board 150 , and the touch control assembly 140 further includes a conductive needle 142 , and the conductive needle 142 is used to conduct the electrical signal received by the conductive ring 141 to the control board 150 , and the control board 150 controls the motor 120 to work according to the electrical signal.

[0042] like Figure 3 As shown, the shaving device 100 includes a control panel 150, which is used to control the operation of the motor 120 of the shaving device 100, and the touch control component 140 further includes a conductive needle 142, which is used to transmit the electrical signal received by the conductive ring 141 and transmit the electrical signal to the control panel 150. Therefore, in this embodiment, the conductive ring 141 can receive the electrical signal generated by the user's touch, and the conductive needle 142 can transmit the electrical signal to the control panel 150, and the control panel 150 can further control the operation of the two motors 120, thereby completing the process of controlling the operation of the shaving device 100 by the user's touch.

[0043] Such an arrangement enables the shaving device 100 to drive two motors 120 at the same time through the user's touch, and further drive the two cutter heads to work, so that the two cutter heads can work synchronously.

[0044] Furthermore, the shaving device 100 also includes a transmission assembly 160, and the transmission assembly 160 includes a first transmission member 161 and a second transmission member 162, the first transmission member 161 is connected to a motor 120 and a cutter head, and the second transmission member 162 is connected to another motor 120 and another cutter head.

[0045] Since the shaving device 100 in this embodiment has two cutter heads and two motors 120, a transmission assembly 160 is provided to transmit power from the motor 120 to the cutter heads. Figure 4 . The first transmission member 161 is used for transmission between the first motor 121 and the first cutter head 131, and the second transmission member 162 is used for transmission between the second motor 122 and the second cutter head 132. The arrangement of the first transmission member 161 and the second transmission member 162 ensures the corresponding driving relationship between the first motor 121 and the first cutter head 131, and between the second motor 122 and the second cutter head 132, so that the work between the two cutter heads is relatively independent, and each motor 120 only needs to drive one cutter head, thereby increasing the service life of the motor 120. Moreover, in extreme cases, that is, when a single-side motor 120 or a single-side head fails, the cutter head or motor 120 on the other side can still work, thereby ensuring the user's usage needs.

[0046] Furthermore, the first transmission member 161 includes a first transmission shaft 163, and the second transmission member 162 includes a second transmission shaft 164. The first transmission shaft 163 and the second transmission shaft 164 are both fixed to the upper portion 114 of the shell, and at least part of the first transmission shaft 163 and the second transmission shaft 164 extend out of the upper surface of the shell 110 and are used to cooperate with the cutter head assembly 130.

[0047] like Figure 2 As shown in , the first transmission shaft 163 and the second transmission shaft 164 both partially extend out of the upper surface of the housing 110 and can be exposed to the upper surface of the housing 110, and the cutter head assembly 130 is connected to the transmission shaft and installed on the transmission shaft. Such a configuration allows the transmission shaft to be exposed outside the housing 110, which facilitates the installation of the cutter head assembly 130. After the transmission assembly 160 is installed, the cutter head assembly 130 is installed on the transmission shaft outside the housing 110, which simplifies the installation steps and facilitates the loading and unloading of the cutter head assembly 130.

[0048] Preferably, the cutter head assembly 130 further includes a cutter head mounting portion 133, the cutter heads are all fixedly mounted on the cutter head mounting portion 133, and each cutter head corresponds to a transmission shaft, and the position of the cutter head on the mounting portion corresponds to the position of the transmission shaft.

[0049] In this embodiment, the cutter head assembly 130 includes a cutter head mounting seat, Figure 2 and Figure 5 The first cutter head 131 and the second cutter head 132 are fixedly mounted on the cutter head mounting seat, and the position between the first cutter head 131 130 and the second cutter head 132 is also fixed. On the cutter head assembly 130, each cutter head is provided with a mounting hole 134 corresponding to the transmission shaft. Therefore, during installation, it is only necessary to match the mounting holes 134 on the cutter head assembly 130 with the position of the transmission shaft on the housing 110. It is only necessary to select any one group of mounting holes 134 and the transmission shaft to be installed in alignment. The installation between the two cutter heads and the transmission shaft can be completed by positioning once, and there is no need to respectively install the first cutter head 131 and the second cutter head 132 on the transmission shaft, thereby reducing the installation steps and making the installation more convenient.

[0050] Continue to refer Figure 1 A control board 150 is provided in the chamber of the lower part 115 of the shell, and the chamber connects the left chamber 112 and the right chamber 113 where the two motors 120 are located. The control board 150 is respectively connected to the first motor 121 and the second motor 122, and controls the operation of the first motor 121 and the second motor 122.

[0051] Preferably, in this embodiment, the control panel 150 includes a main control panel 150 and a touch control panel 152. The main control panel 150 is arranged in the chamber below the housing 110, and is used to control the operation of the entire shaving device 100, including controlling the operation of the first motor 121 and the second motor 122. The main control panel 150 is arranged in the chamber below the housing 110. Since the chamber below the housing 110 can simultaneously connect the left chamber 112 and the right chamber 113 of the housing 110, the main control panel 150 can connect the first motor 121 and the second motor 122, so that it can simultaneously control the first motor 121 and the second motor 122, and maintain the synchronization of the operation between the two cutter heads. In addition, the control panel 150 is arranged below the housing 110, and the space of the housing 110 is fully utilized. Combined with the shape of the housing 110, the internal structure of the housing 110 is reasonably planned, and the compactness of the structure of the shaving device 100 is increased.

[0052] The touch control board 152 is used to connect the touch assembly 140. The touch control board 152 is connected to the above-mentioned conductive pins 142, and the conductive pins 142 first transmit the electrical signal received by the conductive ring 141 to the touch control board 152. The touch control board 152 is connected to the main control board 150, and the main control board 150 receives the signal of the touch control board 152 to control the operation of the motor 120.

[0053] In this embodiment, the touch control panel 152 can be disposed in a cavity on either side of the left or right side of the housing 110 and connected to the main control panel 151. The touch control panel 152 is vertically arranged to fully utilize the space and improve the compactness of the structure of the shaving device 100. In other embodiments, the touch control panel 152 can also be disposed in the space at the bottom of the housing 110, or the function of the touch control panel 152 can be integrated with the main control panel 150, and the main control panel 150 can directly control the touch control assembly 140. This application does not limit this.

[0054] The shaving device 100 also includes a transmission assembly 160, which is arranged on the upper portion 114 of the shell, and at least a portion of the transmission assembly 160 is located above the hollow portion 111. The transmission assembly 160 includes a first transmission member 161 and a second transmission member 162, which respectively correspond to the first motor 121 and the second motor 122 and are respectively connected to the motor 120.

[0055] In this embodiment, for the convenience of the user, the cutter head is arranged in the middle of the upper side of the housing 110, but the motor 120 is respectively arranged in the left chamber 112 and the right chamber 113 on the left and right sides of the housing 110, so the cutter head in the cutter head assembly 130 and its corresponding motor 120 are not in the same vertical plane, and there is a certain horizontal distance, so it is impossible to directly transmit power to the cutter head through the output shaft of the motor 120. Therefore, in this embodiment, a transmission assembly 160 is provided, and the motor 120 of the shaving device 100 can transmit power to the cutter head assembly 130 through the transmission assembly 160. Since the cutter head and the cutter head assembly 130 are also arranged in the upper part 114 of the housing, the transmission assembly 160 is arranged in the space of the upper part 114 of the housing. The transmission assembly 160 includes a first transmission member 161 and a second transmission member 162. The first transmission member 161 is connected to the first cutter head 131 at the top and the first motor 121 at the bottom, and the second transmission assembly 160 is connected to the second cutter head 132 at the top and the second motor 122 at the bottom.

[0056] In this arrangement, the transmission assembly 160 is arranged in the upper space of the housing 110. Since the upper space of the housing 110 is connected to the left chamber 112 and the right chamber 113 on the left and right sides of the housing 110, the transmission assembly 160 is arranged on the upper side of the housing 110 to facilitate its connection with the motor 120, and also facilitates the connection between the transmission assembly 160 and the cutter head. With such a structure, the spatial positions of the motor 120 and the transmission assembly 160 of the shaving device 100 are reasonably allocated, so that the spatial distribution of the structure in the housing 110 of the shaving device 100 is more reasonable.

[0057] For further reference, Figure 4 , refer to Figure 1 The transmission assembly 160 includes a first gear transmission assembly 1611 and a second gear transmission assembly 1621. The first gear transmission assembly 1611 is connected to the first motor 121, and the second gear transmission assembly 1621 is connected to the second motor 122, and is used for transmission between the motor 120 and the cutter head.

[0058] Since the output shaft of the motor 120 is not concentric with the mounting hole 134 of the cutter head, the transmission structure may use a gear transmission assembly 160. In this embodiment, a first gear transmission assembly 1611 is used for transmission between the first cutter head 131 and the first motor 121, and a second gear transmission assembly 1621 is used for transmission between the second cutter head 132 and the second motor 122. Since the gear shape in the gear transmission assembly 160 is a relatively flat structure, in this embodiment, a gear transmission method is used to facilitate the installation of the gear structure on the upper part 114 of the housing, and the required volume is small, which is more conducive to achieving the compactness of the structure of the device.
