[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] In the description of the present utility model, it is necessary to understand that the orientation or position relationship indicated by the terms "upper" and "lower" etc. is based on the orientation or position relationship when the product is normally used.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0029] The following is combined with Figure 1-7 This application is described in further detail.

[0030] The utility model embodiment provides a knife head hidden structure, referring to Figure 1 and Figure 2 The structure in which the blade can be hidden includes a shell 1, a blade assembly 2, an adjustment assembly 3 and a connector 4. The blade assembly 2 is slidably installed inside the shell 1, and the adjustment assembly 3 is slidably installed on the shell 1. Part of the adjustment assembly 3 is located inside the shell 1; part of it is located outside the shell 1. Both sides of the connector 4 are hingedly connected to the adjustment assembly 3 and the blade assembly 2 respectively; the part of the adjustment assembly 3 located outside the shell 1 is convenient for the user to touch and push it to move. After the user pushes the adjustment assembly 3 to move, the adjustment assembly 3 drives the connector 4 to move and drives the blade assembly 2 to move, so that the blade 22 extends out of the shell 1 or is completely retracted inside the shell 1. When not in use, the blade assembly 2 can be retracted into the shell 1 by driving the adjustment assembly 3. When the product falls, the blade assembly 2 is not easily bumped and damaged, and after the blade assembly 2 is retracted and hidden, the tip of the blade is not easy to scratch the skin.

[0031] Reference Figure 2 and Figure 3, an adjustment chamber 11 is provided inside the housing 1. The cutter head assembly 2 and part of the adjustment assembly 3 are both located inside the adjustment chamber 11 and slide inside the adjustment chamber 11. A cutter head outlet 12 is provided on one side of the housing 1. The cutter head outlet 12 is in communication with the inside of the adjustment chamber 11. The adjustment assembly 3 can drive the cutter head assembly 2 to extend out of the cutter head outlet 12 or completely retract into the adjustment chamber 11.

[0032] The cutter head assembly 2 includes a cutter head plate 21 and a cutter head 22. The cutter head 22 is detachably mounted on the cutter head plate 21, and the cutter head plate 21 is hinged to the connecting member 4. When the cutter head 22 needs to be repaired or replaced, it can be conveniently detached from the cutter head plate 21 without damaging the connection relationship between the cutter head plate 21 and the connecting member 4. At the same time, only the cutter head 22 can be removed and replaced, without the need to remove the cutter head plate 21 together, thereby reducing the maintenance and replacement costs. In another embodiment, the cutter head 22 and the connecting member 4 can be directly hinged.

[0033] Among them, let the planes of two adjacent chamber walls in the adjustment chamber 11 be the sliding surface 13 and the adjustment surface 14 respectively. The sliding surface 13 is located on the side of the adjustment surface 14 closer to the cutter head outlet 12. The cutter head plate 21 slides on the sliding surface 13; part of the adjustment assembly 3 located inside the adjustment chamber 11 slides on the adjustment surface 14. Such a setting enables the cutter head plate 21 and the adjustment assembly 3 to each have their own moving planes and moving spaces. When the materials of the cutter head plate 21 and the adjustment assembly 3 are different, the smoothness of the sliding surface 13 and the adjustment surface 14 can be processed and adjusted according to the actual situation, so as to adapt to the smoothness of the sliding of the cutter head plate 21 or the adjustment assembly 3.

[0034] Refer to Figure 2 And Figure 3 , in this embodiment, it is preferably set that the sliding surface 13 and the adjustment surface 14 are inclined to each other, and the included angle between the sliding surface 13 and the adjustment surface 14 is an obtuse angle. Thereby, the occupied space of the adjustment assembly 3 in the adjustment chamber 11 along the sliding direction of the cutter head plate 21 can be reduced, and at the same time, it can also make way for other components, so that the corresponding components can drive the cutter head 22 to operate. In another embodiment, the sliding surface 13 and the adjustment surface 14 may not be inclined, but form a flat plane.

[0035] Refer to Figure 3 And Figure 4, on the chamber wall perpendicular to one side of the sliding surface 13 in the adjustment chamber 11, a guiding strip 15 is integrally formed. The guiding strip 15 is parallel to the sliding surface 13, and the extending direction of the guiding strip 15 is consistent with the sliding direction of the tool rest plate 21. The tool rest plate 21 is located between the guiding strip 15 and the sliding surface 13. One side of the tool rest plate 21 abuts against the side of the guiding strip 15 close to the sliding surface 13; the other side abuts against the sliding surface 13, so that the tool rest plate 21 can stably slide along the extending direction of the guiding strip 15 in a directional manner during the sliding process.

[0036] On the inner wall at the tool head outlet 12, a blocking strip 16 is integrally formed. The blocking strip 16 can limit the movement of the tool rest plate 21, that is, when the tool head 22 is in the extended state, the side of the tool rest plate 21 close to the tool head outlet 12 abuts against the blocking strip 16 to be limited.

[0037] Refer to Figure 3 With Figure 4 , on the outer wall of one side of the housing 1, a fitting inclined surface 17 is provided. The fitting inclined surface 17 is parallel to the sliding surface 13. When the tool head 22 trims an item, the fitting inclined surface 17 can fit with the surface of the item, thereby improving the flatness of the trimming by the tool head 22.

[0038] Combined with Figure 2 Refer to Figure 3 With Figure 5 , the adjustment assembly 3 includes an adjustment plate 31, an adjustment key 32, and a linkage plate 33. The adjustment plate 31 slides on the adjustment surface 14. The adjustment key 32 is located outside the housing 1, and the adjustment plate 31 is connected to the connecting member 4 and slides synchronously. The adjustment key 32 can slide on the housing 1. The linkage plate 33 is used to connect the adjustment plate 31 and the adjustment key 32, so that when the adjustment key 32 is pushed outside the housing 1, the adjustment plate 31 can be driven to move synchronously, and then the tool rest plate 21 is driven to move. In addition, the plane on which the adjustment key 32 slides is inclined with respect to the fitting inclined surface 17, that is, the plane on which the adjustment key 32 slides forms an obtuse angle greater than 180 degrees with the fitting plane, so that the adjustment key 32 does not interfere with the item when the fitting inclined surface 17 fits with the item.

[0039] The adjustment plate 31 and the adjustment key 32 are split into two independent components, which is convenient for assembly during production. In another embodiment, the adjustment plate 31 and the adjustment key 32 can be connected and fixed by bolts. When the adjustment key 32 acts, the adjustment plate 31 drives the tool rest plate 21 to move so as to drive the tool head 22 to extend out of the tool head outlet 12 or completely retract into the adjustment chamber 11.

[0040] Refer to Figure 5 With Figure 6, in this embodiment, preferably two linkage plates 33 are provided. The two linkage plates 33 are symmetrically and spaced apart along the sliding direction perpendicular to the adjustment key 32 on the adjustment key 32. The structures of the two linkage plates 33 are the same. The structure of one linkage plate 33 will be described below as an example.

[0041] The linkage plate 33 is integrally formed on the outer wall of the adjustment key 32 on the side close to the adjustment plate 31. A clamping protrusion 331 is integrally formed on the side of the linkage plate 33 away from the adjustment key 32. A clamping groove 311 is formed on the adjustment plate 31 for the clamping protrusion 331 to pass through. After the clamping protrusion 331 passes through the clamping groove 311, it is located on the side of the adjustment plate 31 away from the adjustment key 32, so that the adjustment key 32 and the adjustment plate 31 are clamped together. Through the above structure, the adjustment key 32 and the adjustment plate 31 are clamped and connected together, making it more convenient to assemble the adjustment key 32 and the adjustment plate 31. In another embodiment, a threaded post can be integrally formed on the side of the linkage plate 33 away from the adjustment key 32. After the threaded post passes through the clamping groove 311, it is connected to the adjustment plate 31 through a nut.

[0042] Refer to Figure 6 and Figure 7 , an adjustment groove 18 for the linkage plate 33 to be inserted and slid is formed on the outer wall of the housing 1. Since two linkage plates 33 are provided, two adjustment grooves 18 are also spaced apart. The two linkage plates 33 are respectively inserted into the two adjustment grooves 18. The cooperation of one adjustment groove 18 and one linkage plate 33 will be described below as an example. The adjustment groove 18 is formed on the outer wall of the housing 1 on the side where the adjustment key 32 slides. The adjustment groove 18 penetrates the adjustment surface 14 and communicates with the adjustment chamber 11. The clamping protrusion 331 can smoothly pass through the adjustment groove 18, and then the clamping protrusion 331 passes through the clamping groove 311 to clamp and connect the adjustment plate 31 and the adjustment key 32. At this time, part of the linkage plate 33 is located in the adjustment groove 18 and drives the adjustment plate 31 to slide as the adjustment key 32 moves.

[0043] Refer to Figure 5 and Figure 6In this embodiment, since the sliding surface 13 and the adjusting surface 14 are arranged at an angle to each other, the tool holder plate 21 and the adjusting plate 31 are both hinged to the connecting member 4, so that the tool holder plate 21 is not easily stuck when the adjusting plate 31 drives the tool holder plate 21 to move. Specifically, the connecting member 4 includes a connecting plate 41, a first hinge column 42 and a second hinge column 43, the first hinge column 42 and the second hinge column 43 are respectively located at opposite ends of the connecting plate 41, the first hinge column 42 and the second hinge column 43 are parallel to each other, and the first hinge column 42 and the second hinge column 43 are both integrally formed with the connecting plate 41. The tool holder plate 21 can be hinged to the first hinge column 42; it can also be hinged to the second hinge column 43. When the tool holder plate 21 is hinged to the first hinge column 42, the adjustment plate 31 is hinged to the second hinge column 43; conversely, if the tool holder plate 21 is hinged to the second hinge column 43, the adjustment plate 31 is hinged to the first hinge column 42. In this embodiment, the tool holder plate 21 is preferably hinged to the first hinge column 42, and the adjustment plate 31 is hinged to the second hinge column 43.

[0044] In detail, the tool holder plate 21 is provided with a first arc-shaped groove 23 for the first hinge column 42 to be inserted and rotated. The opening of the first arc-shaped groove 23 can be toward the sliding surface 13; it can also be toward the side of the tool holder plate 21 that is away from the sliding surface 13; it can also be toward the side of the tool holder plate 21 that is close to the connecting plate 41. In this embodiment, the opening of the first arc-shaped groove 23 is preferably toward the sliding surface 13, and the cross section of the first arc-shaped groove 23 is a major arc. Then, after the first hinge column 42 is inserted into the first arc-shaped groove 23, the sliding surface 13 can block the opening of the first arc-shaped groove 23, so that the first hinge column 42 is not easy to escape from the first arc-shaped groove 23 while ensuring that it can rotate. In addition, when the connecting member 4 is connected to the tool holder plate 21, the first hinge column 42 can be directly inserted into the first arc-shaped groove 23, so that the first hinge column 42 and the tool holder plate 21 are connected more conveniently.

[0045] Reference Figure 5 and Figure 6 , an open arc buckle 34 is integrally formed on one side of the adjustment plate 31 close to the second hinge column 43, and the arc buckle 34 can buckle on the second hinge column 43, so that the adjustment plate 31 and the second hinge column 43 are hinged together. The opening of the arc buckle 34 can be toward the adjustment surface 14; it can also be toward the side away from the adjustment surface 14; it can also be toward the connecting plate 41. In this embodiment, the opening of the arc buckle 34 is preferably toward the adjustment surface 14, so that the arc buckle 34 can play a buckling role on the second hinge column 43, so that the second hinge column 43 is not easy to fall off from the groove of the arc buckle 34. In addition, the cross-section of the arc buckle 34 is a superior arc, so that the second hinge column 43 is not easy to fall off from the arc buckle 34, thereby improving the stability of the arc buckle 34 and the second hinge column 43 after connection.

[0046] Furthermore, the top of the arc of the arc-shaped buckle 34 is located on the side of the adjusting plate 31 away from the adjusting surface 14 and is spaced from the adjusting plate 31 by a certain distance. Thus, when the arc-shaped buckle 34 drives the second hinge post 43 to move closer to the sliding surface 13, the arc-shaped buckle 34 is not likely to contact the sliding surface 13 and cause interference.

[0047] In another embodiment, the connecting member 4 can be a plate body, and both the tool rest plate 21 and the adjusting plate 31 can be hinged to the connecting member 4 through micro hinges. In still another embodiment, the connecting member 4 can be a connecting link. Hinge shafts are provided on both the tool rest plate 21 and the adjusting plate 31, and both sides of the connecting link are respectively hinged to the hinge shaft on the tool rest plate 21 and the hinge shaft on the adjusting plate 31.

[0048] Combined with Figure 3 Refer to Figure 6 With Figure 7 , wherein, a gear position structure 19 is provided on the outer shell 1. When the tool head 22 extends or retracts completely into the adjusting chamber 11 at the tool head outlet 12, the gear position structure 19 can drive the tool head 22 to be limited, thereby improving the stability of the tool head 22 after extension or retraction. The gear position structure 19 can cooperate with the tool rest plate 21; it can also cooperate with the adjusting key 32; it can also cooperate with the adjusting plate 31; it can also cooperate with the linkage plate 33. Specifically, it can be selected according to the actual structure and requirements of the gear position structure 19. In this embodiment, it is preferably that the in-place structure cooperates with the linkage plate 33.

[0049] Specifically, the gear position structure 19 includes a first gear position protrusion 191 and a second gear position protrusion 192. Both the first gear position protrusion 191 and the second gear position protrusion 192 are semi-cylindrical protrusions. Both the first gear position protrusion 191 and the second gear position protrusion 192 are located on the groove wall on the same side of the adjusting groove 18. The first gear position protrusion 191 and the second gear position protrusion 192 are arranged at intervals along the sliding direction of the adjusting key 32, and both the first gear position protrusion 191 and the second gear position protrusion 192 are integrally formed on the outer shell 1. A gear position groove 332 that is snap-fitted with the first gear position protrusion 191 or the second gear position protrusion 192 is provided on one side of the linkage plate 33 close to the groove wall where the first gear position protrusion 191 is located near the adjusting groove 18.

[0050] Combined with Figure 3 Refer to Figure 6 With Figure 7When the linkage plate 33 moves with the adjustment key 32 and the first gear protrusion 191 is inserted into the gear groove 332, the adjustment plate 31 drives the connecting member 4 to move in the direction close to the opening of the cutter head 22, thereby driving the tool holder plate 21 to drive the cutter head 22 to move and extend the cutter head 22 from the cutter head 22 opening, at which time the adjustment key 32 is clamped and limited, thereby preventing the cutter head 22 from being easily retracted into the adjustment chamber 11. When the linkage plate 33 moves with the adjustment key 32 and the second gear protrusion 192 is inserted into the gear groove 332, the adjustment plate 31 drives the connecting member 4 to move in the direction away from the opening of the cutter head 22, thereby driving the tool holder plate 21 to drive the cutter head 22 to move and completely retract the cutter head 22 into the adjustment chamber 11, thereby preventing the adjustment key 32 from being clamped and limited, thereby preventing the cutter head 22 from being easily retracted from the cutter head 22 opening. The gear structure 19 is provided with a first gear protrusion 191 and a second gear protrusion 192, so that the cost is lower and the production and assembly are more convenient.

[0051] In another embodiment, the shift structure 19 can be a ball spring plunger, a mounting hole for inserting the ball spring plunger is opened on the groove wall of the adjustment groove 18, and two slots for inserting the ball head of the ball spring plunger are opened at intervals on the linkage plate 33.

[0052] The implementation principle of a structure in which the cutter head can be hidden in the embodiment of the present application is as follows: when the cutter head 22 needs to be stored inside the housing 1, the user can toggle the adjustment key 32 so that the adjustment key 32 drives the linkage plate 33 to move. When the second gear protrusion 192 is inserted into the gear groove 332, the adjustment plate 31 drives the connecting member 4 to move in a direction away from the opening of the cutter head 22, thereby driving the tool holder plate 21 to drive the cutter head 22 to move and completely retract the cutter head 22 into the adjustment chamber 11, and the second gear protrusion 192 is inserted into the gear groove 332, thereby making it difficult for the cutter head 22 to extend again from the adjustment chamber 11 when in the retracted state. When the product falls on the ground, since the cutter head 22 is completely retracted inside the housing 1, it is not easy for the cutter head 22 to be damaged.

[0053] When the cutter head 22 needs to be extended for use, the user can toggle the adjustment key 32 so that the adjustment key 32 drives the linkage plate 33 to move. When the first gear protrusion 191 is inserted into the gear groove 332, the adjustment plate 31 drives the connecting member 4 to move toward the opening of the cutter head 22, thereby driving the tool holder plate 21 to drive the cutter head 22 to move and extend the cutter head 22 from the opening of the cutter head 22.

[0054] Another embodiment of the utility model provides a hair clipper, comprising the above-mentioned cutter head hideable structure.

[0055] In the hair clipper of the present utility model, the housing 1 is the housing of the hair clipper, and the cutter head 22 is a special cutter head for the hair clipper. That is, the special cutter head for the hair clipper includes a fixed cutter blade mounted on the cutter holder plate 21 and a movable cutter blade movably mounted on the fixed cutter blade. When in use, pushing the adjustment key 32 drives one end of the fixed cutter blade and the movable cutter blade to extend out within the housing 1; when not in use, pushing the adjustment key 32 in the reverse direction drives the fixed cutter blade and the movable cutter blade to completely retract inside the housing 1.

[0056] Among them, an eccentric wheel motor for driving the movable cutter blade to reciprocate and a power supply for supplying power to the eccentric wheel motor are installed inside the housing 1, so that when the movable cutter blade reciprocates, it can cooperate with the fixed cutter blade to achieve trimming.

[0057] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present utility model.
