DETAILED DESCRIPTION

[0029] The present invention will be described in further detail below with reference to the accompanying drawings. Example

[0030] Reference Figure 1 - Figure 7 The utility model discloses a four-way swing structure of a razor head, comprising a handle body 1, a front end of which is provided with a slot 5, a top and a bottom of the slot 5 are symmetrically provided with a pin hole 6, and a bottom wall of the slot 5 is provided with two insertion holes 7;

[0031] The push core assembly 2 includes a push core 201, which is partially located in the card slot 5. The front end of the push core 201 has a second pin hole 8 vertically opened. A pin 9 is rotatably connected in the second pin hole 8. The two ends of the pin 9 are respectively fixedly connected in the first pin hole 6.

[0032] The U-shaped spring piece 3 has a U-shaped assembly groove 10 at the middle position of the bottom of the pushing core 201. The rotating section of the U-shaped spring piece 3 is assembled in the U-shaped assembly groove 10, and the extension section of the U-shaped spring piece 3 is horizontally inserted into the insertion hole 7.

[0033] The shaving head assembly 4 includes a horn connector 401 and a cutter head 402. The cutter head 402 is rotatably connected to the horn connector 401. A slot 11 is formed on the side of the horn connector 401 away from the cutter head 402. The slot 11 is connected to the push core 201 via a snap-on connector 12.

[0034] In this embodiment, the observation Figure 1 It can be seen that the handle body 1 and the shaving head assembly 4 can be used by the user to shave. The shaving head assembly 4 includes a horn connector 401 and a cutting head 402. The cutting head 402 is rotatably connected to the horn connector 401. When the cutting head 402 is in contact with the face, the relative rotation between the cutting head 402 and the horn connector 401 achieves a perfect contact with the skin, thereby improving shaving efficiency.

[0035] However, in most conventional manual razors on the market, the movement direction of the cutter head 402 during shaving is to swing up and down around the support point and rotate a certain angle to fit the facial contour and achieve the purpose of shaving. The movement direction of this structure does not fundamentally solve the problem of the difficulty of shaving grip from a structural perspective. The cutter head 402 does not have the effect of automatically correcting the left and right directions, which poses a safety hazard during shaving.

[0036] Therefore, observe Figure 4 and Figure 5It can be found that a slot 5 is provided at the top of the handle body 1, and a pushing core component 2 is provided in the slot 5, which includes a pushing core 201. The pushing core 201 is partially located in the slot 5, and a pin hole 8 is vertically provided at the front end of the pushing core 201. A pin 9 is rotatably connected in the pin hole 8, and the two ends of the pin 9 are respectively fixedly connected to the pin hole 6. A slot 11 is provided on the side of the horn connector 401 away from the cutter head 402, and the slot 11 is connected to the pushing core 201 through a clamping member 12, so that the razor head assembly 4 connected thereto can be rotated along the axis of the pin 9, thereby achieving the effect of lateral swing of the razor head assembly 4, so that the razor can automatically correct the shaving direction, thereby minimizing the problem of facial scratches caused by consumers using a manual razor due to incorrect gripping method of the razor handle and incorrect technique of shaving their facial beard, thereby reducing safety hazards.

[0037] Since the push core assembly 2 is connected to the handle body 1 in a rotating manner, the shaver head 402 will shake, which will affect the shaving process and may even scratch the skin. Figure 5 It can be found that a U-shaped assembly groove 10 is provided in the middle position of the bottom of the pushing core 201, and the rotating section of the U-shaped spring piece 3 is assembled in the U-shaped assembly groove 10, and the extension section of the U-shaped spring piece 3 is horizontally inserted into the socket 7, so that when the cutter head 402 swings horizontally, the U-shaped mounting groove squeezes the U-shaped spring piece 3, causing the U-shaped spring piece 3 to deform. Then, when the cutter head 402 leaves the face, the pressure on the U-shaped spring piece 3 disappears, and the U-shaped spring piece 3 restores the pushing core 201 under the action of elastic force, which can be used to prevent the cutter head 402 of the razor from shaking during use, and also allows the cutter head 402 to automatically return to its original position after use.

[0038] In a further preferred embodiment of the present invention, Figure 3 and Figure 6 As shown, the pushing core assembly 2 also includes a pushing member 202, a floating member 203 and an ejecting member 204. A through groove 13 is provided on the side of the pushing core 201 close to the socket 7, and a floating member 203 is slidably connected in the through groove 13. The side of the floating member 203 away from the handle body 1 is concave to form an ejecting groove 14. The front section of the ejecting groove 14 is slidably connected to the ejecting member 204, and the rear section of the ejecting groove 14 is connected to a spring 15. The spring 15 is fixedly connected to the ejecting member 204. The pushing member 202 is located above the handle body 1, and its bottom is downwardly inserted into the card slot 5, and is connected to the floating member 203 through the card connector 16.

[0039] In this embodiment, a through groove 13 is opened on one side of the push core 201 close to the socket 7, and a floating part 203 is slidably connected in the through groove 13. A push 202 is provided above the handle body 1, and the bottom of the push 202 is inserted downward into the card slot 5 and is connected to the floating part 203 through the snap-connector 16. When the push 202 is pressed, the push 202 can be used to move the floating part 203 forward, so that the floating part 203 touches the horn connector 401, thereby unlocking the snap-connector 12, thereby achieving the purpose of quickly replacing the cutter head 402.

[0040] Since the cutter head 402 is connected to the horn connector 401 in a rotating manner, the cutter head 402 and the horn connector 401 will shake, affecting the shaving of the cutter head 402. Therefore, the floating part 203 is concave on the side away from the handle body 1 to form an ejection groove 14. The front part of the ejection groove 14 is slidably connected to the ejection part 204, and the rear part of the ejection groove 14 is connected to the spring 15. The spring 15 is fixedly connected to the ejection part 204. The ejection part 204 can be set to press the cutter head 402 under the action of the spring 15, so that the cutter head 402 always maintains an angle when not in use.

[0041] In a further preferred embodiment of the present invention, Figure 4 As shown, the second clamping member 16 includes a toggle block 161 and a stopper 162 . The bottom of the pusher 202 is fixedly connected to the toggle block 161 . The inner wall of the ejection groove 14 is fixedly connected to the stopper 162 for blocking the toggle block 161 .

[0042] In this embodiment, a toggle block 161 is connected to the bottom of the pusher 202, and a stopper 162 for blocking the toggle block 161 is fixedly connected to the inner wall of the ejection groove 14. When the pusher 202 is pushed, the floating part 203 can be moved to have the effect of contacting the horn connector 401, thereby realizing the rapid replacement of the razor head assembly 4.

[0043] In a further preferred embodiment of the present invention, Figure 6 As shown, a receiving groove 17 for receiving the pin 9 is formed downwardly through the top of the ejector 204 , and one side of the receiving groove 17 extends along the length direction of the ejector 204 to create a space for accommodating the pin 9 .

[0044] In this embodiment, since the push core 201 rotates around the pin 9, and the push core 201 is provided with a ejector 204, the ejector 204 will interfere with the pin 9 during rotation, affecting the lateral swing of the cutter head 402. Figure 6It can be found that a receiving groove 17 for accommodating the pin 9 is provided at the top of the ejector 204. When the cutter head 402 swings laterally, the ejector 204 will also rotate around the axis of the pin 9, thereby avoiding the ejector 204 from conflicting with the pin 9 and ensuring the stability of the lateral swing of the cutter head 402.

[0045] Since the ejector 204 needs to slide in the through slot 13, in order to prevent the pin 9 from blocking the sliding of the ejector 204, one side of the receiving slot 17 is extended along the length direction of the ejector 204 to create a space for avoiding the pin 9, thereby ensuring the stability of the ejector 204.

[0046] In a further preferred embodiment of the present invention, Figure 6 and Figure 7 As shown, an opening 18 for the ejection member 204 to extend out is formed on the inner wall of the slot 11 , and two ejection surfaces 19 contacting the floating member 203 are symmetrically provided on the upper and lower sides of the opening 18 .

[0047] In this embodiment, since the horn connector 401 is connected to the push core 201 via the clamping member 12, and the ejector 204 needs to contact the cutter head 402, an opening 18 is provided in the slot 11 of the horn connector 401 so that the ejector 204 can pass through the opening 18 and contact the cutter head 402, thereby ensuring stable operation of the ejector 204.

[0048] Two ejection surfaces 19 are provided on the upper and lower sides of the opening 18, and are in contact with the floating member 203. The two ejection surfaces 19 are symmetrically arranged on both sides of the opening 18, so that when the pusher 202 is pushed, the floating member 203 contacts the ejection surfaces 19, so that the clamping member 12 is unlocked, thereby achieving a quick replacement effect of the razor head assembly 4.

[0049] In a further preferred embodiment of the present invention, Figure 6 As shown, the left and right side walls of the through slot 13 are both provided with limiting slots 20 away from the handle body 1 , and the outer wall of the floating member 203 is fixedly connected with a protrusion 21 extending into the limiting slot 20 .

[0050] In this embodiment, since the ejection groove 14 of the floating member 203 is connected to the ejection member 204 through the spring 15, and the ejection member 204 contacts the cutter head 402, the floating member 203 will slide toward the depth of the slot 5 under the push of the spring 15. Therefore, in order to prevent the floating member 203 from penetrating too deep into the slot 5, causing the floating member 203 to separate from the horn connector 401, thereby affecting the replacement efficiency of the razor head assembly 4, a limiting groove 20 is provided on the left and right side walls of the through groove 13 away from the handle body 1, and the outer wall of the floating member 203 is fixedly connected with a protrusion 21 extending into the limiting groove 20.

[0051] In a further preferred embodiment of the present invention, Figure 6 As shown, the outer wall of the ejector 204 is fixedly connected to the limiting block 22 , and the side of the through slot 13 away from the handle body 1 is fixedly connected to a limiting rod 23 for blocking the limiting block 22 .

[0052] In this embodiment, since a spring 15 is provided between the ejector 204 and the floating member 203, the ejector 204 will continuously contact the cutter head 402. Therefore, when the shaving head assembly 4 is replaced, the ejector 204 will lose its support and pop out, affecting the use of the shaver. Figure 6 It can be seen that the outer wall of the ejector 204 is fixedly connected to the limit block 22, and the side of the through slot 13 away from the handle body 1 is fixedly connected to a limit rod 23 for blocking the limit block 22. When the razor head assembly 4 is replaced, the limit block 22 on the ejector 204 is blocked by the limit rod 23, which can effectively prevent the ejector 204 from flying out.

[0053] In a further preferred embodiment of the present invention, Figure 3 、 Figure 4 and Figure 7 As shown, the snap-in member 12 includes a connecting member buckle point 121 and a connecting groove 122. The top and bottom of the pushing core 201 extending out of the card slot 5 are both provided with a connecting groove 122, and the inner wall of the slot 11 is fixedly connected with a connecting member buckle point 121 for inserting into the connecting groove 122.

[0054] In this embodiment, combined with Figure 3 、 Figure 4 and Figure 7 It can be seen that by providing connection grooves 122 at the top and bottom of the side where the pushing core 201 extends out of the card slot 5, a connector buckle point 121 for inserting into the connection groove 122 is fixedly connected to the inner wall of the slot 11. When the shaving head assembly 4 is installed, it can be fixed at multiple points, which can effectively improve the installation stability of the shaving head assembly 4.

[0055] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
