Description

Technical Field

[0001] This invention relates to the field of pop-up nose hair trimmers, and in particular to a pop-up nose hair trimmer. Background Technology

[0002] Nose hair trimmers typically have a protective cover that houses the blade assembly between the cover and the main body, protecting it. Specifically, when using the nose hair trimmer, the user must first remove the protective cover before the blade assembly can operate. Conversely, when not in use, the user must then replace the protective cover. This repeated installation and removal of the cover is cumbersome and inconvenient for users. Furthermore, when the protective cover is on the main body, the blade assembly is sealed between the cover and the main body, making it susceptible to bacterial growth and unpleasant odors, resulting in uncleanliness and unsanitary conditions.

[0003] For example, CN214394285U discloses a nose hair trimmer that is easy to clean, which includes a blade assembly, a main body shell, and a top shell. The top shell covers the blade assembly between the top shell and the main body shell. Specifically, when using the nose hair trimmer, the user needs to remove the top shell first so that the blade assembly can work. At the same time, when not using the nose hair trimmer, the user then puts the top shell back on the main body shell. During this process, the top shell needs to be installed and removed back and forth, which is cumbersome and makes it difficult for the user to use. At the same time, when the top shell is on the main body shell, the blade assembly is sealed between the main body shell and the top shell, which can easily cause bacteria to grow on the blade assembly and produce unpleasant odors, resulting in unclean and unhygienic blade assembly. Summary of the Invention

[0004] One objective of this invention is to provide a pop-up nose hair trimmer to solve the problems that when using a nose hair trimmer, the user needs to remove the protective cover before the blade assembly can work, and when not using the nose hair trimmer, the user needs to put the protective cover back on the pop-up nose hair trimmer body. This process requires the protective cover to be installed and removed back and forth, which is cumbersome and makes it difficult for the user to use. At the same time, when the protective cover is on the nose hair trimmer body, the blade assembly is sealed between the protective cover and the nose hair trimmer body, which can easily cause bacteria to grow on the blade assembly and produce unpleasant odors, resulting in the blade assembly being unclean and unhygienic.

[0005] A pop-up nose hair remover includes:

[0006] Holding body;

[0007] A protective cover is movably connected to the end of the gripping body, and the protective cover is provided with a storage cavity and a blade hole communicating with the storage cavity;

[0008] The blade assembly includes a blade body and an elastic element. The blade body is housed in the receiving cavity and movably connected to the end of the gripping body. The blade body is also snapped onto the inner wall of the protective cover to restrict the elastic element between the blade body and the gripping body and to accumulate elastic force.

[0009] The protective cover is rotatable relative to the gripping body to release the restriction of the blade body on the elastic element, so that the elastic element can release force to drive the blade body to move relative to the gripping body and extend out of the storage cavity through the blade hole.

[0010] In one embodiment, the protective cover is provided with a slot and a groove, the slot and the groove are connected, and the length extension direction of the slot forms an angle with the length extension direction of the groove. The blade body is provided with a locking member, which is embedded in the slot and abuts against the groove wall, so that the blade body restricts the elastic member between the blade body and the gripping body. When the protective cover rotates relative to the gripping body, the locking member disengages from the slot and slides into the groove, thereby releasing the restriction of the blade body on the elastic member, so that the elastic member releases its elastic force to drive the locking member to move along the trajectory of the groove. The movement of the locking member in turn drives the blade body to move relative to the gripping body to extend out of the storage cavity.

[0011] In one embodiment, the length extension direction of the slot is parallel to the movement direction of the blade body, and the length extension direction of the slide is at an angle to the movement direction of the blade body; the blade body can also drive the locking member to move along the direction trajectory of the slide and slide into the slot, so that the blade body retracts into the receiving cavity, and when the locking member slides into the slot, the locking member abuts against the groove wall of the slot, so that the blade body restricts the elastic member between the blade body and the gripping body.

[0012] In one embodiment, the slot extends away from the blade hole to the edge of the protective cover to form a guide opening. When the card moves along the trajectory of the slot to the guide opening, the card can disengage from the slot through the guide opening, so that the protective cover is disengaged from the gripping body.

[0013] In one embodiment, one of the protective cover and the gripping body is provided with a protrusion, and the other is provided with a groove; when the protective cover is connected to the gripping body, the protrusion is received in the groove to prevent the protective cover from detaching from the gripping body; when the clip moves to the guide opening, the protective cover can overcome the elastic force of the protrusion engaging in the groove to allow the protrusion to detach from the groove, and the protective cover to detach from the gripping body.

[0014] In one embodiment, a limiting sleeve is provided at the end of the gripping body. The limiting sleeve is used to receive the blade body and is housed in the receiving cavity. The limiting sleeve is provided with a moving groove. The locking member passes through the moving groove to be embedded in the locking groove. When the elastic member drives the blade body to move relative to the gripping body, the locking member moves along the length extension direction of the moving groove.

[0015] In one embodiment, one of the blade body and the gripping body is provided with a fixing post, and the other is provided with a storage groove, and the length extension direction of the storage groove is parallel to the movement direction of the blade body; one end of the elastic member is engaged with the fixing post, and the other end of the elastic member is received in the storage groove.

[0016] In one embodiment, the blade body includes a rotating part that is circumferentially limited and can rotate synchronously, and a blade head. The opposite ends of the rotating part are respectively connected to the gripping body and the blade head. The blade head is provided with a blade. The blade head is engaged with the inner wall of the storage cavity and is housed in the storage cavity to restrict the elastic element between the blade head and the gripping body and accumulate elastic force. When the protective cover rotates relative to the gripping body, the protective cover releases the restriction of the blade head on the elastic element, so that the elastic element releases elastic force to drive the blade head to move relative to the gripping body to extend out of the storage cavity, and at the same time, the rotating part can extend to be housed in the blade head at all times.

[0017] In one embodiment, the pop-up nose hair trimmer further includes a sensor. When the blade body is housed in the storage cavity, the sensor is in a disconnected state, and when the blade body is in a disconnected state, the gripping body is in a standby or off state. When the blade body extends out of the storage cavity, the sensor is in a connected state, and when the blade body is in a connected state, the gripping body is in an on state, thereby driving the blade inside the blade body to rotate.

[0018] In one embodiment, the sensor includes a Hall switch and a magnetic element. One of the Hall switch and the magnetic element is disposed in the gripping body, and the other is disposed in the blade head body. When the blade assembly is received in the receiving cavity, the magnetic element senses the Hall switch, causing the Hall switch to be in an open state. In the open state, the gripping body is in a standby or off state. When the blade head body extends out of the receiving cavity, the magnetic element moves away from the Hall switch in the direction of blade assembly movement, causing the magnetic element to disconnect from the Hall switch. This allows the Hall switch to be in a connected state. In the connected state, the gripping body is in an activated state, driving the blade inside the blade head body to rotate.

[0019] As can be seen from the above technical solutions, the embodiments of the present invention have at least the following advantages and positive effects:

[0020] This invention provides a pop-up nose hair trimmer. Because the protective cover can extend and retract the blade body into the storage cavity, the protective cover does not need to be repeatedly installed and removed during this process, making operation simple and convenient for users. Simultaneously, the elastic element can release elastic force to automatically extend the blade body into the storage cavity, further enhancing user convenience. Furthermore, because the protective cover has a blade hole, odors from the blade body can escape through the blade hole when it is housed in the storage cavity, and the air inside the storage cavity can exchange with the outside atmosphere. This prevents bacteria growth and unpleasant odors from developing on the blade body, thus solving the problem of unclean and unhygienic blade bodies. Attached Figure Description

Detailed Implementation

[0037] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0039] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] refer to Figure 1 This invention provides a pop-up nasal hair remover 1, which has the function of removing nasal hair. In use, the user inserts the blade end of the pop-up nasal hair remover 1 into the user's nasal cavity. The blade inside the pop-up nasal hair remover 1 rotates to cut the nasal hair, thus achieving the purpose of removing the nasal hair. After the nasal hair is removed, the pop-up nasal hair remover 1 is removed from the nasal cavity, and then closed.

[0041] refer to Figure 2 and Figure 3 The pop-up nose hair trimmer 1 includes a gripping body 10, a protective cover 20, and a blade assembly 30. The gripping body 10 serves as a handle for the user to hold. The protective cover 20 is movably connected to the end of the gripping body 10 and has a storage cavity 201 and a blade hole 202 communicating with the storage cavity 201. The blade assembly 30 is housed in the storage cavity 201 and movably connected to the end of the gripping body 10. The outer periphery of the blade assembly 30 is engaged with the inner wall of the protective cover 20 to restrict the movement of the blade assembly 30 relative to the gripping body 10.

[0042] Specifically, when using the pop-up nose hair remover 1, the user can hold the holding body 10 with their hand and then rotate the protective cover 20 relative to the holding body 10 to release the restriction on the movement of the blade assembly 30 by the protective cover 20. After the restriction is released, the protective cover 20 drives the blade assembly 30 to move relative to the holding body 10 so that it extends out of the storage cavity 201 through the blade hole 202. The extended part of the blade assembly 30 extends into the nasal cavity. At this time, the holding body 10 is activated to drive the blade inside the blade assembly 30 to rotate. The rotating blade cuts the nose hairs to achieve the purpose of removing nose hairs.

[0043] After the nasal hairs are removed, the blade assembly 30 is removed from the nasal cavity. The user can apply external force to the blade assembly 30. Under the action of external force, the blade assembly 30 moves in the opposite direction to the protective cover 20 to retract into the storage cavity 201. When the blade assembly 30 retracts into the storage cavity 201, the outer periphery of the blade assembly 30 is engaged with the inner wall of the protective cover 20 to restrict the movement of the blade assembly 30 relative to the holding body 10. At this time, the holding body 10 is closed, so that the blades in the blade assembly 30 stop rotating, thereby closing the pop-up nasal hair remover 1.

[0044] Figure 2 The illustration shows that the grip body 10 and the protective cover 20 are cylindrical to facilitate user gripping. It is understood that in other embodiments, the grip body 10 and the protective cover 20 may also be prismatic structures. Therefore, the present invention does not impose any limitations on the external structure of the grip body 10 and the protective cover 20.

[0045] refer to Figure 4 When the protective cover 20 covers the blade assembly 30 within the storage cavity 201, the protective cover 20 also accommodates the end of the gripping body 10 within the storage cavity 201. For this purpose, a limiting sleeve 101 is provided at the end of the gripping body 10. The limiting sleeve 101 accommodates the blade assembly 30 within the storage cavity 201, thus connecting the protective cover 20 to the gripping body 10. After the limiting is released, the protective cover 20 moves the blade assembly 30 relative to the limiting sleeve 101, causing the blade assembly 30 to extend out of the storage cavity 201. It is understood that in other embodiments, the limiting sleeve 101 can be omitted, in which case the blade assembly 30 is positioned at the end of the gripping body 10 and accommodated within the storage cavity 201.

[0046] The limiting sleeve 101 is provided with a moving groove 102, the length extension direction of the moving groove 102 is parallel to the length extension direction of the limiting sleeve 101, and the blade assembly 30 is provided with a locking piece 301, which passes through the moving groove 102 to lock onto the inner wall of the protective cover 20, thereby restricting the movement of the blade assembly 30 relative to the holding body 10.

[0047] When the protective cover 20 rotates relative to the gripping body 10, it releases the restriction on the movement of the blade assembly 30 relative to the gripping body 10. After the restriction is released, the protective cover 20 causes the locking piece 301 to move relative to the moving groove 102. The movement of the locking piece 301 then causes the blade assembly 30 to move relative to the limiting sleeve 101 to extend out of the receiving cavity 201. At the same time, since the locking piece 301 passes through the moving groove 102, the moving groove 102 can restrict the blade assembly 30 from rotating circumferentially around the limiting sleeve 101 during movement to prevent deflection, making the movement of the blade assembly 30 more stable.

[0048] It should be noted that in this embodiment, there are two movable slots 102, which are respectively disposed at opposite ends of the limiting sleeve 101. There are also two locking pieces 301, which pass through the two movable slots 102 to abut against the inner wall of the protective cover 20. When the protective cover 20 rotates relative to the gripping body 10, the protective cover 20 drives the two locking pieces 301 to move along the two movable slots 102 respectively, so that the two locking pieces 301 drive the blade assembly 30 to move relative to the gripping body 10 to extend out of the storage cavity 201. At the same time, since there are two locking pieces 301, the force on the opposite sides of the blade assembly 30 is even, making the movement of the blade assembly 30 more stable, and at the same time, it can better restrict the circumferential rotation of the blade assembly 30 around the limiting sleeve 101 to prevent deflection.

[0049] It is understood that in other embodiments, the number of card pieces 301 is one or more and they are arranged at intervals along the circumference of the blade assembly 30, and the number of moving slots 102 is also one or more and they are arranged at intervals along the circumference of the limiting sleeve 101. Therefore, the present invention does not limit the number of card pieces 301 and moving slots 102.

[0050] One of the two movable slots 102 extends through the limiting sleeve 101 along its length, allowing one of the two locking pieces 301 to disengage from the limiting sleeve 101 via the movable slot 102. After one locking piece 301 disengages from the movable slot 102, the blade assembly 30 can drive the other locking piece 301 to disengage from the movable slot 102, thereby enabling the blade assembly 30 to disengage from the limiting sleeve 101.

[0051] The gripping body 10 is equipped with a motor 103 and a battery 104. The motor 103 is connected to the blade assembly 30 and electrically connected to the battery 104 through a circuit structure. Both the motor 103 and the battery 104 are housed within the gripping body 10 and arranged sequentially along its length, minimizing the space occupied and thus reducing the overall size of the gripping body 10. When the blade assembly 30 extends out of the storage cavity 201, the battery 104 supplies power to the motor 103 through the circuit structure. Driven by this power, the motor 103 rotates, causing the blades within the blade assembly 30 to rotate and remove whiskers. When the blade assembly 30 retracts into the storage cavity 301, the battery 104 disconnects from the circuit structure, causing the motor 103 to stop, and the blades within the blade assembly 30 to stop rotating.

[0052] It is understood that in other embodiments, the battery 104 may be omitted, and in this case, an external power source supplies power to the motor 103. Therefore, the present invention does not impose any limitations on the specific configuration of the battery 104.

[0053] The gripping body 10 also includes a circuit board 105, which is electrically connected to the motor 103 and the battery 104. The length extension direction of the circuit board 105 is parallel to the length extension direction of the gripping body 10. The circuit board 105 occupies less internal space in the gripping body 10, allowing for a smaller overall size. When the blade assembly 30 extends out of the storage cavity 201, the circuit board 105 connects the motor 103 and the battery 104, enabling the battery 104 to supply power to the motor 103 via the circuit board 105, causing the motor 103 to rotate. Conversely, when the blade assembly 30 retracts into the storage cavity 201, the circuit board 105 disconnects the motor 103 from the battery 104, causing the motor 103 to stop rotating and remain in an off state without power.

[0054] refer to Figure 5 The protective cover 20 is also provided with a slot 203 and a slide 204. Both the slot 203 and the slide 204 are connected to the receiving cavity 201. The extension direction of the slot 203 and the slide 204 form an angle. The slot 203 is located on the side of the protective cover 20 away from the cutter head hole 202, and the slide 204 is located on the side of the protective cover 20 near the cutter head hole 202. Specifically, the locking member 301 can pass through the moving groove 102 to be embedded in the slot 204, and the locking member 301 abuts against the groove wall of the slot 203, thereby restricting the movement of the cutter head assembly 30 relative to the limiting sleeve 101.

[0055] When the protective cover 20 rotates relative to the holding body 10, the locking piece 301 disengages from the locking slot 203 and slides into the sliding groove 204, thereby releasing the movement restriction of the blade assembly 30 on the limiting sleeve 101. After the restriction is released, the protective cover 20 drives the locking piece 301 to move along the trajectory of the sliding groove 204 within the sliding groove 204. The movement of the locking piece 301 then drives the blade assembly 30 to move relative to the limiting sleeve 101 to extend out of the storage cavity 201, thereby realizing the use of the pop-up nose hair trimmer 1.

[0056] After using the pop-up nose hair trimmer 1, the user can apply external force to the blade assembly 30. Under the action of the external force, the blade assembly 30 drives the locking piece 301 to move along the reverse trajectory of the slide groove 204 and slide into the locking slot 203. The reverse movement of the locking piece 301 along the slide groove 204 drives the blade assembly 30 to retract into the receiving cavity 201. When the locking piece 301 slides into the locking slot 203, the locking piece 301 abuts against the groove wall of the locking slot 203, thereby restricting the movement of the blade assembly 30 relative to the limiting sleeve 101, so as to close the pop-up nose hair trimmer 1.

[0057] It should be noted that in this embodiment, the length extension direction of the slot 203 is parallel to the moving direction of the blade assembly 30, and the length extension direction of the slide groove 204 forms an angle with the moving direction of the blade assembly 30. It is understood that in other embodiments, the length extension direction of the slide groove 204 may also be parallel to the moving direction of the blade assembly 30; therefore, this invention does not impose any limitations on the length extension directions of the slot 203 and the slide groove 204.

[0058] It should be understood that in this embodiment, there are two slots 203 and two sliding grooves 204, respectively located on opposite sides of the inner wall of the protective cover 20. The two locking pieces 301 can be respectively embedded in the two slots 203 and can move relative to the sliding grooves 204, making the movement of the blade assembly 30 more stable when it moves relative to the limiting sleeve 101. It is understood that in other embodiments, the number of slots 203 and sliding grooves 204 can also be one or more; therefore, this invention does not limit the number of slots 203 and sliding grooves 204.

[0059] The slot 203 extends away from the blade hole 202 to the edge of the protective cover 20, forming a guide opening 205. When the blade assembly 30 retracts into the receiving cavity 201, the user can apply external force to the protective cover 20 to move it relative to the length extension direction of the limiting sleeve 101. This causes the retaining piece 301 to disengage from the slot 203 through the guide opening 205. After the retaining piece 301 disengages from the slot 203, the protective cover 20 disengages from the limiting sleeve 101, thus achieving the removal of the protective cover 20. Simultaneously, after the protective cover 20 is removed, the user can clean the blade assembly 30, or disengage the blade assembly 30 from the limiting sleeve 101 for cleaning.

[0060] It should be understood that in other embodiments, the guide port 205 is omitted. In this case, the end of the slot 203 extending away from the cutter hole 202 to the edge of the protective cover 20 is blocked. Since the end of the slot 203 is blocked, when the protective cover 20 moves relative to the length extension direction of the limiting sleeve 101, the locking member 301 cannot disengage from the slot 203, thereby restricting the protective cover 20 from disengaging from the limiting sleeve 101. Therefore, the present invention does not impose any restrictions on the specific setting of the guide port 205.

[0061] refer to Figure 6 The blade assembly 30 includes a blade body 302 and an elastic element 303. The blade body 302 is housed in a limiting sleeve 101 and the limiting sleeve 101 is movably connected. Different sides of the blade body 302 are connected to the locking element 301, and the blade body 302 abuts against the groove wall of the locking groove 203 through the locking element 301, thereby restricting the elastic element 303 between the blade body 302 and the holding body 10 and accumulating elastic force.

[0062] When the protective cover 20 rotates relative to the holding body 10, the protective cover 20 causes the locking piece 301 to disengage from the slot 203 and slide into the slide groove 204, thereby releasing the restriction of the blade body 302 on the elastic member 303. After the restriction is released, the elastic member 303 releases its elastic force to drive the locking piece 301 to move along the trajectory of the slide groove 204. The movement of the locking piece 301 causes the blade body 302 to move relative to the limiting sleeve 101 to extend out of the storage cavity 201. The extended part of the blade body 302 extends into the nasal cavity. At this time, the battery 105 supplies power to the motor 103 through the circuit board 105, causing the motor 103 to start and rotate. The rotation of the motor 103 then drives the blade inside the blade body 302 to rotate to cut the nasal hair, thereby achieving the purpose of removing nasal hair.

[0063] After the nose hairs are removed, the user can remove the blade body 302 from the nasal cavity. The user then applies external force to the blade body 302. Under the action of the external force, the blade body 302 drives the locking piece 301 to overcome the elastic force of the elastic member 303, so that the locking piece 301 moves along the reverse trajectory of the slide groove 204 and slides into the slot 203. The reverse movement of the locking piece 301 causes the blade body 302 to retract into the receiving cavity 201. When the locking piece 301 slides into the slot 203, the locking piece 301 abuts against the groove wall of the slot 203 to restrict the movement of the blade body 302 and restrict the elastic member 303 between the blade body 302 and the holding body 10. The elastic member 303 accumulates elastic force. At this time, the circuit board 105 disconnects the connection between the motor 103 and the battery 104. Without power drive, the motor 103 stops and is in the off state. The blades in the blade body 302 also stop rotating, thus closing the solid pop-up nose hair remover 1.

[0064] It should be noted that in this embodiment, the transition area at the connection between the slot 203 and the slide 204 is small, so that the protective cover 20 only needs a small rotation angle for the clip 301 to disengage from the slot 203 and slide into the slide 204. Then, under the action of the elastic member 303, the blade body 302 automatically extends out of the storage cavity 201. This means that the user does not need to twist the protective cover 20 significantly to extend the blade body 302 out of the storage cavity 201, saving time and effort and making it convenient for the user.

[0065] It should be explained that in this embodiment, there are two elastic elements 303. The two elastic elements 303 can release a stronger elastic force to automatically extend the cutter head assembly 302 out of the receiving cavity 201. It can be understood that in other embodiments, there may be one or more elastic elements 303. Therefore, the present invention does not limit the number of elastic elements 303.

[0066] In this invention, the protective cover 20 can extend the blade body 302 out of the storage cavity without requiring repeated installation and removal, making operation simple and convenient for users. Simultaneously, the elastic element 303 can release elastic force to automatically extend the blade body 302 out of the storage cavity 201, further enhancing user convenience. Furthermore, the protective cover has a blade hole 202, allowing odors from the blade body 302 to escape through the hole when it is housed in the storage cavity 201. The air inside the storage cavity 201 can also exchange with the outside atmosphere, preventing bacterial growth and unpleasant odors in the blade body 302, thus solving the problem of uncleanliness and unsanitary conditions.

[0067] refer to Figure 7 and Figure 8 In one embodiment, one of the blade body 302 and the gripping body 10 is provided with a fixing post 106, and the other is provided with a receiving groove 304. Specifically, in this embodiment, the fixing post 106 is disposed in the gripping body 10 and located within the limiting sleeve 101, and the receiving groove 304 is disposed in the blade body 302, with the length extension direction of the receiving groove 304 parallel to the movement direction of the blade body 302. It can be understood that in other embodiments, the fixing post 106 is disposed in the blade body 302, and the receiving groove 304 is disposed in the gripping body 10. Therefore, the present invention does not limit the arrangement of the fixing post 106 and the receiving groove 304. Specifically, one end of the elastic member 303 is engaged with the fixing post 106, and the other end of the elastic member 303 is received in the receiving groove 304, thereby limiting the position of the elastic member 303 from shifting when the blade body 302 moves relative to the limiting sleeve 101, so as to achieve relative fixation of the position of the elastic member 303. Meanwhile, when there are multiple elastic elements 303, the number of fixing posts 106 and storage slots 304 are corresponding to the number of elastic elements 303.

[0068] refer to Figure 8 and Figure 9 In one embodiment, the blade body 302 includes a rotating part 305 and a blade head 306 that are circumferentially limited and can rotate synchronously. Both the rotating part 305 and the blade head 306 are housed in the limiting sleeve 101. The opposite ends of the rotating part 305 are respectively connected to the motor 103 and the blade head 103, and the end of the rotating part 305 is housed in the blade head 306. Different ends of the blade head 306 form receiving grooves 304 for receiving elastic members 303. The periphery of different sides of the blade head 306 is respectively connected to the retaining member 301, so that the blade head 306 abuts against the groove wall of the retaining groove 203 through the retaining member 301, thereby restricting the elastic member 303 between the blade head 306 and the gripping body 10 and accumulating elastic force.

[0069] When the protective cover 20 rotates relative to the gripping body 10, the protective cover 20 causes the locking piece 301 to disengage from the slot 203 and slide into the slide groove 204, thereby releasing the restriction of the blade head 306 on the elastic member 303. After the restriction is released, the elastic member 303 releases its elastic force to move the locking piece 301 along the trajectory of the slide groove 204. The movement of the locking piece 301 then causes the blade head 306 to move relative to the limiting sleeve 101 to extend out of the receiving cavity 201. The extended part of the blade head 306 can reach into the nasal cavity. At this time, the battery 105 supplies power to the motor 103 through the circuit board 105, causing the motor 103 to start and rotate. The rotation of the motor 103, in turn, drives the blade inside the blade head 306 to rotate through the rotating part 305 to cut the nasal hair, thereby achieving the purpose of removing nasal hair. At the same time, when the blade head 306 moves relative to the limiting sleeve 101, the length of the rotating part 305 can be extended, so that the end of the rotating part 305 is always received inside the blade head 306.

[0070] After the nose hairs are removed, the user can detach the blade head 306 from the nasal cavity. The user then applies external force to the blade head 306. Under the action of the external force, the blade head 306 drives the locking piece 301 to overcome the elastic force of the elastic member 303, causing the locking piece 301 to move along the reverse trajectory of the sliding groove 204 and slide into the groove 203. This causes the blade head 306 to retract into the receiving cavity 201. When the locking piece 301 slides into the groove 203, it abuts against the groove wall of the groove 203, thereby restricting the elastic member 303 between the blade head 306 and the grip body 10 and accumulating elastic force. At this time, the rotating part 305 is housed inside the blade head 306. When the blade head 306 retracts into the receiving cavity 201, the circuit board 105 disconnects the connection between the motor 103 and the battery 104. Without power, the motor 103 stops and is in an off state. The blades inside the blade head 306 also stop rotating, thus closing the pop-up nose hair remover 1.

[0071] refer to Figure 10 In one embodiment, the rotating part 305 includes a first rotating member 307, a second rotating member 308, and a spring 309. The end of the first rotating member 307 is connected to the motor 103. One end of the second rotating member 308 is housed in the first rotating member 307 and can move relative to the first rotating member 307. The other end of the second rotating member 308 is circumferentially limited to the cutter head 306. The spring 309 is disposed between the first rotating member 307 and the second rotating member 308 and stores elastic force.

[0072] When the blade head 306 moves relative to the limiting sleeve 101 to extend out of the receiving cavity 201, the spring 309 releases its elastic force, causing the spring 309 to drive the second rotating member 308 to move relative to the first rotating member 307 so that it is always housed in the blade head 306 and circumferentially limited in the blade head 306. At the same time, the motor 103 starts to drive the first rotating member 307 to rotate, and the first rotating member 307 drives the second rotating member 308 to rotate, so that the second rotating member 308 drives the blade inside the blade head 306 to rotate.

[0073] Simultaneously, when the blade head 306 retracts into the receiving cavity 201, the second rotating member 308 is housed within the first rotating member 307, and both the first rotating member 307 and the second rotating member 308 are housed within the blade head 306. The spring 309 is compressed to accumulate elastic force, and at this time, the motor 103 can be stopped, so that the first rotating member 307, the second rotating member 308, and the blades within the blade head 306 also stop rotating, thereby closing the pop-up nose hair remover 1.

[0074] Continue to refer to Figure 10 In one embodiment, the first rotating member 307 is provided with a sliding groove 310, the length extension direction of the sliding groove 310 being parallel to the length extension direction of the first rotating member 307. The second rotating member 308 is provided with a hook 311, the hook 311 being received in the first rotating member 307, and the end of the hook 311 being received in the sliding groove 310. When the spring 309 releases its elastic force, the spring 309 drives the hook 311 to move along the sliding groove 208, so that the end of the second rotating member 308 is always received in the cutter head 306 and circumferentially limited to the cutter head 306. At the same time, when the hook 311 moves to its limit position, the hook 311 engages with the groove wall of the sliding groove 310 to prevent the hook 311 from disengaging from the first rotating member 307.

[0075] It should be noted that in this embodiment, there are two sliding grooves 310, located on different sides of the first rotating member 307, and there are also two hooks 311. Both hooks 311 are housed within the first rotating member 307, and their ends are respectively housed within the two sliding grooves 310. The number of hooks 311 corresponds one-to-one with the number of sliding grooves 310. When the spring 309 releases its elastic force, the two hooks 311 move along the sliding grooves 208, making the movement of the second rotating member 308 more stable. Simultaneously, the holding force between the two hooks 311 and the groove wall of the sliding groove 310 is stronger, further preventing the second rotating member 308 from detaching from the first rotating member 307. It is understood that in other embodiments, the number of sliding grooves 310 and hooks 311 may be single or multiple. Therefore, this invention does not impose any limitation on the number of sliding grooves 310 and hooks 311.

[0076] refer to Figure 9In one embodiment, the blade head 306 includes a housing 312, a rotating frame 313, and a blade assembly 314. The housing 312 is provided with a nose hair groove 315. The rotating frame 313 is housed within the housing 312 and can rotate circumferentially around the housing 312. The rotating frame 313 is connected to a second rotating member 308 and houses the end of the second rotating member 308 within the rotating frame 313. The blade assembly 314 is located at the end of the rotating frame 313 away from the second rotating member 308, and the blade edge of the blade assembly 314 abuts against the inner wall of the housing 312. Different ends of the housing 312 form receiving grooves 304 for accommodating an elastic member 303. The opposite sides of the outer periphery of the housing 312 are respectively connected to retaining members 301, so that the housing 312 abuts against the groove wall of the retaining groove 203 via the retaining members 301, thereby confining the elastic member 303 between the housing 312 and the gripping body 10 and accumulating elastic force.

[0077] When the protective cover 20 rotates to cause the clip 301 to disengage from the slot 203 and slide into the slide groove 204, the elastic element 303 releases its elastic force to cause the clip 301 to move along the trajectory of the slide groove 204. The movement of the clip 301 causes the outer shell 312 to move relative to the limiting sleeve 101 to extend out of the storage cavity 101. The extended part of the outer shell 312 can extend into the nasal cavity, so that the nasal hairs extend into the outer shell 312 through the nasal hair groove 315. At this time, the motor 103 is started. The rotation of the motor 103 drives the rotating frame 313 to rotate through the second rotating element 308, so that the rotating frame 313 drives the blade assembly 314 to rotate to cut off the nasal hairs that have extended into the outer shell 312, so as to realize the use of the pop-up nasal hair trimmer 1.

[0078] After the nose hairs are removed, the user removes the outer shell 312 from the nasal cavity. The user then applies external force to the outer shell 312. Under the action of the external force, the outer shell 312 drives the locking piece 301 to overcome the elastic force of the elastic member 303, so that the locking piece 301 moves along the reverse trajectory of the slide groove 204 and slides into the slot 203. The reverse movement of the locking piece 301 causes the outer shell 312 to retract into the receiving cavity 201. When the locking piece 301 slides into the slot 203, the locking piece 301 abuts against the groove wall of the slot 203 to restrict the movement of the outer shell 312 and restrict the elastic member 303 between the outer shell 312 and the holding body 10. The elastic member 303 accumulates elastic force. At this time, the circuit board 105 disconnects the connection between the motor 103 and the battery 104. Without power drive, the motor 103 stops and is in the off state. The rotating frame 313 stops rotating, and the blade assembly 314 also stops rotating, thus closing the solid pop-up nose hair remover 1. At the same time, when the outer shell 312 retracts into the receiving cavity 201, the first rotating member 307 and the second rotating member 308 are both housed in the rotating frame 313.

[0079] It should be noted that in this embodiment, there are multiple nasal hair grooves 315. These multiple nasal hair grooves 315 are disposed at the end of the outer casing 312 and arranged circumferentially along the outer casing 312. Furthermore, the multiple nasal hair grooves 315 are interconnected. The multiple nasal hair grooves 315 allow nasal hairs to more easily enter the outer casing 312 for removal by the blade assembly 314, thereby facilitating user operation. It is understood that in other embodiments, the nasal hair groove 315 may be a single groove; therefore, the present invention does not impose any limitation on the number of nasal hair grooves 315.

[0080] refer to Figure 9 and Figure 11 In one embodiment, the blade assembly 314 includes a first blade 316, a second blade 317, and a spring 318. Both the first blade 316 and the second blade 317 are housed at the end of the rotating frame 313 and are movably connected to the end of the rotating frame 313. The cutting edges of the first blade 316 and the second blade 317 are exposed at different ends of the rotating frame 313. The spring 318 is housed at the end of the rotating frame 313 and its two ends abut against the first blade 316 and the second blade 317, respectively. The spring 318 releases its elastic force, causing the cutting edges of the first blade 316 and the second blade 317 to abut against the inner wall of the outer casing 312. When nasal hairs extend into the outer casing 312 through the nasal hair groove 315, the rotating frame 313 drives the first blade 316 and the second blade 317 to rotate to cut the nasal hairs, thereby achieving the purpose of trimming nasal hairs.

[0081] refer to Figure 4 and Figure 5 In one embodiment, one of the protective cover 20 and the gripping body 10 is provided with a protrusion 206, and the other is provided with a groove 107. Specifically, in this embodiment, the protrusion 206 is disposed on the inner wall of the protective cover 20, and the groove 107 is disposed on the periphery of the limiting sleeve 101. It can be understood that in other embodiments, the protrusion 206 may be disposed on the periphery of the limiting sleeve 101, and the groove 107 may be disposed on the inner wall of the protective cover 20. Therefore, the present invention does not limit the arrangement of the protrusion 206 and the groove 107.

[0082] When the limiting sleeve 101 is received in the receiving cavity 301, the protrusion 206 is received in the groove 107, thereby preventing the protective cover 20 from detaching from the limiting sleeve 101, thus achieving the installation and fixation of the protective cover 20. At the same time, when the clip 301 moves to the guide port 205, the user can apply external force to the protective cover 20. Under the action of external force, the protective cover 20 can overcome the elastic force of the protrusion 206 being engaged in the groove 107, causing the protrusion 206 to detach from the groove 107, so that the protective cover 20 detaches from the limiting sleeve 101 along its length extension, thereby achieving the disassembly of the protective cover 20.

[0083] It should be noted that, in this embodiment, the protrusion 206 is circumferentially arranged around the inner wall of the protective cover 20 along the protective cover 20, and the groove 107 is circumferentially arranged around the outer periphery of the limit sleeve 101 along the limit sleeve 101. It can be understood that in other embodiments, the protrusion 206 and the groove 107 may also not be arranged in an annular shape.

[0084] Reference Figure 4 and Figure 11 , in one embodiment, the pop-up nose hair trimmer 1 further comprises a sensor 40, wherein the sensor 40 is configured to switch the circuit to an off state when the outer housing 312 is accommodated in the accommodating cavity 301, and at this time the holding main body 10 is in a standby or off state. The sensor 40 is further configured to switch the circuit to a connected state when the outer housing 312 extends out of the accommodating cavity 301, and at this time the holding main body 10 is in an on state.

[0085] In one embodiment, the sensor 40 comprises a Hall switch 401 and a magnetic member 402, one of the Hall switch 401 and the magnetic member 402 is arranged on the holding main body 10, and the other is arranged on the blade assembly 30. Specifically, in this embodiment, the Hall switch 401 is arranged on the circuit board 105, and the magnetic member 402 is arranged on the outer housing 312. It can be understood that in other embodiments, the Hall switch 401 is arranged on the outer housing 206, and the magnetic member 402 is arranged on the circuit board 105. Therefore, the present invention does not make any limitation on the arrangement mode of the Hall switch 401 and the magnetic member 402.

[0086] When the outer housing 312 retracts into the accommodating cavity 301, the magnetic member 402 induces with the Hall switch 401, so that the Hall switch 401 is in an off state, and in the off state, the holding main body 10 is in a standby or off state. Meanwhile, when the outer housing 312 extends out of the accommodating cavity 301, the induction between the magnetic member 402 and the Hall switch 401 is disconnected, so that the Hall switch 401 is in a connected state, and in the connected state, the battery 104 can supply power to the motor 103 through the circuit board 105, so that the motor 103 is in a starting state to rotate, and the rotation of the motor 103 further drives the first blade 213 and the second blade 214 to rotate through the rotating holder 201, so as to realize the use of the pop-up nose hair trimmer 1.

[0087] It should be noted that, in other embodiments, the sensor 40 may also not adopt the form of the Hall switch 401 to realize closing and opening of the circuit. For example, the sensor 40 may adopt a magnetic reed switch or a contact type push switch, and the working principle of the magnetic reed switch is the same as that of the Hall switch 401, which will not be repeated herein.

[0088] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
