Description

[Technical Field]

[0001] The present application relates to the technical field of care appliances, and in particular to sensory shaving heads and shaving devices. [Background technology]

[0002] An electric shaving device is a hairdressing appliance that uses electricity to move the inner blade to shave beards and sideburns. Conventional electric shaving devices consist of a stainless steel mesh blade, inner blade, micromotor, and housing. The mesh blade has many holes through which beards can grow. The micromotor is driven by electrical energy to move the inner blade, which cuts beards that grow into the holes using a shearing principle. Electric shaving devices are small, easy to carry, and can be used anytime, making them the first choice for men to take when traveling.

[0003] Currently, intelligent sensing rotary electric shaving devices on the market use skin-sensing technology, which uses the weak electrical current on the human body to activate and switch on the shaving device. This technology utilizes a microcharge sensor inside the shaving device, which sensitively detects the electrical current when it comes into contact with the skin and automatically turns on instantly. However, the biggest drawback of this technology is that it cannot effectively prevent accidental contact. If a hand or other part of the human body touches the inner blade, or if the inner blade needs to be cleaned with water, the switch will automatically trigger and activate the shaving device. This not only causes unnecessary power loss but also poses a certain risk of safety accidents. Summary of the Invention [Problem to be solved by the invention]

[0004] Based on this, the object of the present application is to provide a sensory shaving head and a shaving device including this sensory shaving head to solve the problem that when using conventional shaving devices, it is inevitable to accidentally touch the inner blade, causing the switch to be automatically triggered and the shaving device to operate, resulting in meaningless power loss and even a certain risk of safety accidents.

[0010] In one embodiment, a limiting groove is provided in a portion of the mesh blade bracket located within the housing, a positioning block is provided in the limiting groove, the mesh blade and the mesh blade elastic piece are connected to the positioning block, and when the mesh blade moves relative to the mesh blade bracket, the positioning block can move within the limiting groove, and the two opposing groove walls of the limiting groove abut against the positioning block, thereby limiting the movement distance of the positioning block and causing recoverable deformation in the mesh blade elastic piece.

[0011] In one embodiment, a mesh blade positioning frame is provided within the housing and is detachably connected to the housing, the mesh blade positioning frame including a sleeve and a connecting ring connected to the sleeve, and the mesh blade elastic piece is engaged with the connecting ring.

[0012] In one embodiment, the inner wall of the housing is provided with a plurality of snap fits spaced apart along the circumferential direction, all of which pass through the sleeve and engage with the end face of the sleeve to restrict axial movement of the sleeve.

As can be seen from the above, when the mesh blade assembly comes into contact with the skin, the conductive assembly does not immediately come into contact with the first conductive element, so the shaving device provided in the present application not only has a sensing conductive function, but also can avoid the shaving device being activated due to false triggering of the switch, thereby saving power and avoiding the occurrence of safety accidents.

[0023] Referring to Figures 1 and 2, Figure 1 shows a schematic diagram of a sensory shaving head 100 provided in one embodiment of the present application, and Figure 2 shows a cross-sectional view of the sensory shaving head 100 provided in this embodiment. The sensory shaving head 100 provided in one embodiment of the present application includes a housing 110, an inner blade assembly 120, a mesh blade assembly 130, and a conductive assembly 140, and an intermediate frame 111 is provided within the housing 110, which divides the cavity surrounded by the housing 110 into an upper cavity and a lower cavity, and a first conductive element 150 is provided on the intermediate frame 111, and the conductive assembly 140 is provided on the intermediate frame 111, and there are multiple inner blade assemblies 120, each of which is arranged within the housing 110 and includes an inner blade 121 and a transmission module 122, and the transmission module 122 of each inner blade assembly 120 is transmission-connected to the corresponding inner blade 121 and electrically connected to the first conductive element 150. Accordingly, there are multiple mesh blade assemblies 130, each connected to the housing 110 and covering the inner blade 121 of the corresponding inner blade assembly 120, the mesh blade assembly 130 is used to contact the skin and apply a certain pressure to the skin, and through the skin sensing action, the mesh blade assembly 130 is electrically connected to the first conductive element 150 via the conductive assembly 140, thereby causing the transmission module 122 to also be electrically connected to the first conductive element 150, and when electrically connected to the first conductive element 150, the inner blade 121 is driven to rotate around its central axis, and when the inner blade 121 rotates, it can cut hairs based on the shearing principle.

[0024] In this way, when the mesh blade assembly 130 comes into contact with the skin and is electrically connected to the first conductive element 150 via the conductive assembly 140 under a certain contact force, the inner blade 121 can be rotated, sensing conductivity is achieved, and the user can use it easily.

[0025] However, as mentioned in the background art, the biggest drawback of the sensing conduction technology in the prior art is that it cannot effectively avoid accidental contact, and when a hand or other part of the human body touches the mesh blade assembly 130 or when parts inside the mesh blade assembly 130 need to be cleaned with water, the switch will automatically trigger and the shaving device 10 will operate, which not only causes unnecessary power loss but also creates a certain risk of safety accidents.

[0026] Therefore, to solve this problem, in one embodiment, the mesh blade assembly 130 is elastically connected to the housing 110, and when an external force is applied, for example, when the skin comes into contact with the inner blade 121, the mesh blade assembly 130 can move relative to the housing 110 from the outside to the inside of the housing 110 under the action of the contact force of the skin, and the conductive assembly 140 is elastically arranged on the intermediate frame 111 and can move relative to the intermediate frame 111.

[0027] Specifically, as shown in FIG. 3, the mesh blade assembly 130 includes a mesh blade bracket 132, which is arranged at an angle relative to the outside of the housing 110 and is rotatably connected to the housing 110; at the same time, the mesh blade bracket 132 is also elastically connected to the housing 110 via a second elastic element 133 such as a spring, so that under the action of an external force, the entire mesh blade assembly 130 can rotate at a predetermined angle relative to the housing 110; and at the same time, when the rotation of the entire mesh blade assembly 130 is limited and stopped by the housing 110, the second elastic element 133 is stretched and can provide an elastic force to return the mesh blade assembly 130 to its original position.

[0028] In the initial state, as shown in Figures 2 and 3, the conductive assembly 140 does not contact the first conductive element 150, and when the entire mesh blade assembly 130 rotates relative to the housing 110, the mesh blade bracket 132 can contact the conductive assembly 140, and the conductive assembly 140 can move relative to the intermediate frame 111. Therefore, when the mesh blade assembly 130 moves from the outside to the inside of the housing 110, the conductive assembly 140 can abut against the mesh blade assembly 130 and move relative to the intermediate frame 111, and as a result, one end of the conductive assembly 140 away from the mesh blade assembly 130 can abut against the first conductive element 150, thereby electrically connecting the first conductive element 150 and the transmission module 122.

[0029] As such, when the mesh blade assembly 130 comes into contact with the skin and applies a certain amount of pressure to the skin, the mesh blade assembly 130 rotates a certain angle before coming into contact with the conductive assembly 140, and the conductive assembly 140 itself moves relative to the intermediate frame 111 before coming into contact with the first conductive element 150. Therefore, there is a certain time lag between when the mesh blade assembly 130 comes into contact with the skin and when the conductive assembly 140 comes into contact with the first conductive element 150, and the conductive assembly 140 does not immediately come into contact with the first conductive element 150. Therefore, the shaving device 10 provided in the present application not only has a sensing conductive function, but also can prevent the shaving device 10 from being operated due to erroneous triggering of the switch, thereby saving power and preventing safety accidents.

[0030] Furthermore, based on the above embodiment, the mesh blade assembly 130 further includes a mesh blade 131 that covers the inner blade 121 and is connected to the inner blade 121, and the mesh blade 131 has a plurality of holes that penetrate both the inner and outer sides thereof, and when shaving, hairs extend into the mesh blade 131 through the holes, and when the inner blade 121 rotates, the inner blade 121 cuts the hairs that have extended into the mesh blade 131, thereby protecting the skin and achieving a smoother shaving experience.

[0031] 4, the mesh blade 131 is preferably movably inserted into the mesh blade bracket 132 and protrudes from the outer surface of the mesh blade bracket 132, so that when the mesh blade 131 comes into contact with the skin, the skin first comes into contact with the mesh blade 131, and the mesh blade 131 and the inner blade 121 can move a certain distance from the outside to the inside of the housing 110 under the action of the contact force of the skin, but are restricted from moving by the mesh blade bracket 132, and the entire mesh blade assembly 130 then rotates at a certain angle relative to the housing 110. At the same time, a mesh blade positioning frame 160 is detachably provided within the housing 110, and a mesh blade elastic piece 170 connected to the mesh blade 131 is engaged with the mesh blade positioning frame 160, and the mesh blade elastic piece 170 has a certain elasticity and is configured to generate an elastic force that returns the mesh blade 131 when the mesh blade 131 moves relative to the mesh blade bracket 132. As a result, when the mesh blade 131 comes into contact with the skin, the mesh blade 131 and the inner blade 121 can move together in a direction from the outside to the inside of the housing 110, and when the mesh blade 131 is separated from the skin, both the mesh blade 131 and the inner blade 121 can return to their original position due to the elastic force provided by the mesh blade elastic piece 170.

[0032] As such, with the above configuration, the mesh blade 131 comes into flexibly contact with the skin, and the mesh blade 131 is movable relative to the mesh blade bracket 132, and the mesh blade bracket 132 can also rotate relative to the housing 110. Compared to conventional embodiments in which the mesh blade bracket 132 is not movable and the mesh blade 131 can only move relative to the mesh blade bracket 132, or the mesh blade bracket 132 can only rotate relative to the housing 110, the mesh blade 131 fits better to the skin, and the inner blade 121 can completely shave beard and hair, and since the mesh blade 131 does not come into complete contact with the skin, it is possible to avoid leaving any areas unshaved or making the skin more susceptible to injury.

[0033] 2, in one embodiment, the transmission module 122 has a gear meshing structure, and includes an input gear 1221 and an output gear 1222 meshing with the input gear 1221, the inner blade 121 is connected to the output gear 1222, the input gear 1221 is connected to an input shaft 1223, and the output gear 1222 is connected to an output shaft 1224, and a connecting shaft spring 1225 is provided between the input shaft 1223 and the input gear 1221, and another connecting shaft spring 1225 is provided between the output shaft 1224 and the output gear 1222. Thus, after the mesh blade 131 comes into contact with the skin, the mesh blade assembly 130 abuts against the output shaft 1224, and in addition to the elastic force generated by the second elastic element 133 and the mesh blade elastic piece 170, the connecting shaft spring 1225 also generates a recoverable elastic deformation, thereby further increasing the flexibility of the mesh blade 131 in contact with the skin. Of course, the transmission module 122 may be any other type of transmission structure, and is not particularly limited here.

[0034] As shown in the figure, regarding the method of connecting the mesh blade 131 and the mesh blade elastic piece 170, and the restricting structure of the mesh blade 131, in one embodiment, as shown in Figure 4, the mesh blade bracket 132 is provided with a stopper structure 1321 at an end close to one end within the housing 110, and the stopper structure 1321 is bent from the edge of the end of the mesh blade bracket 132, so that the stopper structure 1321 and the step portion within the mesh blade bracket 132 form a restricting groove 1322 in the part of the mesh blade bracket 132 located within the housing 110, and a positioning block 180 is provided within the restricting groove 1322, and the mesh blade 131 and the mesh blade elastic piece 170 are connected to the positioning block 180. When the mesh blade 131 moves relative to the mesh blade bracket 132, the positioning block 180 can move within the limiting groove 1322, and the two opposing groove walls of the limiting groove 1322 abut against the positioning block 180, thereby limiting the movement distance of the positioning block 180 and causing recoverable deformation in the mesh blade elastic piece 170.

[0035] Furthermore, the mesh blade bracket 132 is provided with a positioning guide pillar 1323, and the positioning block 180 is provided with a through hole that passes through both opposing ends thereof, and the positioning guide pillar 1323 is inserted into the through hole, so that the positioning block 180 is fitted into the positioning guide pillar 1323 and can move only along the axial direction of the positioning guide shaft.Therefore, the positioning guide pillar 1323 acts as a guide when the positioning block 180 moves, preventing the positioning block 180 from deviating from the specified trajectory during movement, and the mesh blade 131 will not shift when moving relative to the mesh blade bracket 132.

[0036] 5, the structure of the conductive assembly 140 includes a pressure member 141, a conductive elastic piece 142, and a first elastic element 143, the pressure member 141 is connected to the intermediate frame 111, the conductive elastic piece 142 is provided at one end of the pressure member 141 remote from the mesh blade assembly 130, and the first elastic element 143 is disposed on the intermediate frame 111 and connected to the conductive elastic piece 142. Specifically, the pressure member 141 is made of an elastic material, and can undergo recoverable deformation under the action of an external force. The conductive elastic piece 142 includes a connecting portion 1421, and a first contact portion 1422 and a second contact portion 1423 connected to the connecting portion 1421. The connecting portion 1421 is movably disposed on the intermediate frame 111 and is used to abut against the crimping member 141 when the crimping member 141 generates a recoverable deformation, and simultaneously abut the second contact portion 1423 against the first conductive element 150. Illustratively, the first elastic element 143 is a spring, one end of which is connected to the first contact portion 1422. When the crimping member 141 abuts against the first contact portion 1422, the first elastic element 143 generates an elastic deformation and can provide an elastic force to restore the first contact portion 1422 and the second contact portion 1423.

[0037] In one embodiment, the intermediate frame 111 is provided with mounting holes 111a penetrating both sides thereof, and the pressure-receiving members 141 are disposed at the positions of the mounting holes 111a. Specifically, the pressure-receiving members 141 include a plastic member 1411 and a silicone member 1412 that is fitted into the plastic member 1411 and connected to the intermediate frame 111. The silicone member 1412 seals the mounting holes 111a to ensure waterproofing, and is relatively soft so that it can undergo recoverable deformation when subjected to the contact force of the mesh blade assembly 130. The plastic member 1411 is relatively hard and is covered with the silicone member 1412, whose role is to support the silicone member 1412 so that the mesh blade assembly 130 can press the pressure-receiving member 141 and the pressure-receiving member 141 has sufficient contact force to contact the conductive elastic piece 142.

[0038] Regarding the specific shape of the connecting portion 1421 of the conductive elastic piece 142, the connecting portion 1421 includes a first sub-connecting portion 1421a and a second sub-connecting portion 1421b connected to each other, with one end of the first sub-connecting portion 1421a connected to the first contact portion 1422 and one end of the second sub-connecting portion 1421b connected to the second contact portion 1423. The first sub-connecting portion 1421a and the second sub-connecting portion 1421b are arranged at an angle so that the connecting portion 1421 is substantially V-shaped, whereby one end of the first sub-connecting portion 1421a remote from the first contact portion 1422 and one end of the second sub-connecting portion 1421b remote from the second contact portion 1423 form protrusions that contact the intermediate frame 111.

[0039] From this, it can be easily understood that when the pressure head assembly abuts against the crimping member 141, and then the crimping member 141 abuts against the first contact portion 1422 of the conductive elastic piece 142, similar to the principle of leverage, the second contact portion 1423 tilts upward and abuts against the first conductive element 150, thereby establishing electrical conductivity between the first conductive element 150 and the transmission module 122.

[0040] 6 and 7, the first conductive element 150 has a structure consisting of a metal plate 151 and a conductive spring 152, and there are two metal plates 151, each representing a positive electrode and a negative electrode. As shown in the figures, one of the two metal plates 151 is connected to one end of the conductive spring 152, and the other is connected to the other end of the conductive spring 152. Accordingly, the second contact portion 1423 has two contacts, one contact being used to abut against one of the metal plates 151 and the other contact being used to abut against the other metal plate 151.

[0041] In addition, the role of the conductive elastic piece 142 here is similar to that of a bridge. When the two contact points of the second contact portion 1423 respectively abut against the two metal plates 151, the positive and negative poles of the first conductive element 150 are conducted, forming a loop, thereby electrically conducting the first conductive element 150 and the transmission module 122.

[0042] Referring to Figure 4, the structure of the mesh blade positioning frame 160 includes a sleeve 161 and a connecting ring 162 connected to the sleeve 161, and the mesh blade elastic piece 170 is engaged with the connecting ring 162, which is arranged opposite the inner blade 121 and is used to abut against the inner blade 121 when the mesh blade 131 and the inner blade 121 move relative to the mesh blade bracket 132, thereby preventing the mesh blade 131 and the inner blade 121 from falling off.

[0043] In one embodiment, as shown in Figures 4 and 8, the inner wall of the housing 110 is provided with a plurality of snap fits 112 spaced apart along the circumferential direction, and all of the snap fits 112 pass through the sleeve 161 and engage with the end faces of the sleeve 161, so that the opposing ends of the sleeve 161 cannot move along their axial direction due to the restrictions of the snap fits 112 and the inner wall of the housing 110.

[0044] Optionally, several grooves 1611 are provided at one end of the sleeve 161, and several bosses 113 are provided correspondingly on the inner wall of the housing 110, and the bosses 113 engage with the grooves 1611 to restrict the sleeve 161 from rotating in the circumferential direction in which the plurality of snap fits 112 are arranged, thereby effectively preventing the mesh blade positioning frame 160 from shaking and rotating during transportation or use of the shaving device. Of course, the bosses 113 may be provided at the end of the sleeve 161, and the grooves 1611 may be provided on the inner wall of the housing 110.

[0045] Preferably, the depth of the groove 1611 and the height of the boss 113 are relatively small, and when the inner blade 121 needs to be replaced or cleaned and the mesh blade positioning frame 160 needs to be removed, the sleeve 161 is simply moved and rotated around its own central axis, at which point the boss 113 engages with another groove 1611 and the connecting ring 162 is disengaged from the inner blade 121 (i.e., not facing the inner blade 121), allowing the inner blade 121 to be removed.

[0046] More preferably, a first limiting block 1612 is provided on the outer wall of the sleeve 161, and a second limiting block 114 is provided on the inner wall of the housing 110, and the first limiting block 1612 and the second limiting block 114 abut against each other to limit the circumferential rotation angle of the sleeve 161. In this way, even if the sleeve 161 is rotated a certain angle to remove the connecting ring 162 from the inner blade 121 before replacing the inner blade 121, the sleeve 161 can be further prevented from continuing to rotate.

[0047] Furthermore, to facilitate removal of each component within the sensory shaving head 100, the housing 110 is designed to be removable. Specifically, as shown in FIG. 2, the housing 110 includes an upper housing 115 and a lower housing 116. The inner wall of the upper housing 115 forms an upper cavity, and the inner wall of the lower housing 116 forms a lower cavity. The mesh blade assembly 130 is partially disposed within the upper cavity, and at least a portion of the first conductive element 150 and at least a portion of the second conductive element 3212 are disposed within the lower cavity. The output shaft 1224 of the transmission module 122 passes through the partition. That is, a portion of the transmission module 122 is disposed within the upper cavity and connected to the inner blade 121, and another portion is disposed within the lower cavity and connected to the drive module 320. By installing magnets within the upper and lower cavities, the upper and lower housings 115 and 116 are magnetically connected, ensuring reliable current conduction while facilitating removal and cleaning of the internal components.

[0048] The number of mesh blade assemblies 130 in the sensory shaving head 100 is not limited, and may be one or any number. Naturally, by providing a plurality of mesh blade assemblies 130, a better shaving effect can be obtained.

[0049] Furthermore, one embodiment of the present application further provides a shaving device 10, and referring to Figures 9 and 10, the shaving device 10 of this embodiment includes a main body 200, a drive unit 300, and the sensory shaving head 100 described in the above embodiment, wherein the sensory shaving head 100 is connected to the drive unit 300, and the drive unit 300 is disposed within the main body 200.

[0050] 10, in one embodiment, the drive unit 300 includes a control module 310 and a drive module 320, the control module 310 includes a battery 311 and a main control system 312 connected to the battery 311, the battery 311 is used to supply power to the main control system 312, the main control system 312 may be a PCB board or the like that provides control signals for controlling the operation of the drive module 320. The drive module 320 includes a drive source 321 and a transmission assembly 322, the drive source 321 is used to provide power or electrical signals, and the transmission assembly 322 is used to transmit the power and electrical signals provided by the drive source 321 to the sensory shaving head 100, so that the sensory shaving head 100 can achieve a shaving function.

[0051] 11, the transfer assembly 322 is provided with a connection terminal 3221, and the drive source 321 is provided with an adapter sleeve 3211 and a second conductive element 3212 communicatively connected to the control module 310, one end of the connection terminal 3221 is connected to the first conductive element 150 of the sensory shaving head 100, and the other end is connected to the second conductive element 3212, thereby realizing an electrical connection between the drive module 320 and the inner blade 121. One end of the adapter sleeve 3211 is connected to the drive source 321, and the other end is detachably connected to the input shaft 1223 of the transmission module 122, so that the control module 310 can control the drive module 320 to drive the transmission module 122 and rotate the inner blade 121.

[0052] As can be seen from the above, by using the shaving device 10 provided in the present application, the drawback of accidentally touching the mesh blade 131 and causing the shaving device 10 to automatically start operating can be effectively avoided to a certain extent, and contact with the skin can be made truly without any blind spots, allowing for a more thorough shave without damaging the skin.

[0053] The technical features of the above embodiments can be combined in any way, and for the sake of brevity, not all possible combinations of the technical features in the above embodiments are listed, but as long as there is no contradiction between the combinations of these technical features, they should be considered within the scope of this specification.

[0054] The above examples merely illustrate some embodiments of the present application, and although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. Those skilled in the art may make various modifications and improvements without departing from the spirit of the present application, and all such modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be governed by the appended claims. [Explanation of symbols]
