Magnetic nose hair trimmer

Abstract

This invention relates to a magnetic nose hair remover, which includes a holding body and a blade assembly. The holding body has a storage cavity and a vent hole communicating with the storage cavity, and a pushing member is provided on the holding body, which is movable relative to the holding body. The blade assembly is housed in the storage cavity and does not protrude from the vent hole, and the blade assembly and the pushing member are magnetically attracted. When the pushing member moves relative to the holding body, the pushing member drives the blade assembly to move relative to the holding body through the induced magnetic force between the pushing member and the blade assembly, so that the blade assembly extends out of the storage cavity through the vent hole. Since the pushing member can drive the blade assembly to extend and retract into the storage cavity, the operation is simple and convenient for users. At the same time, the odor on the blade assembly can be discharged through the vent hole, thereby making it less likely for bacteria to grow and for unpleasant odors to be produced on the blade assembly, thus solving the problem of unclean and unhygienic blade assembly.

Description

Technical Field

[0001] This invention relates to the field of nose hair trimmers, and in particular to a magnetic 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 with the rotating body. 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 unclean and unhygienic 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] The present invention provides a magnetic nose hair trimmer to solve the problems of the following: 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 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 unclean and unhygienic blade assembly.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A magnetic nose hair remover includes:

[0007] The gripping body is provided with a storage cavity and a vent hole communicating with the storage cavity, and the gripping body is provided with a pushing member, which is movable relative to the gripping body;

[0008] The blade assembly is housed in the receiving cavity and does not protrude from the vent hole, and the blade assembly is magnetically attracted to the pusher; when the pusher moves relative to the gripping body, the pusher drives the blade assembly to move relative to the gripping body through the induced magnetic force between the pusher and the blade assembly, so that the blade assembly extends out of the receiving cavity through the vent hole.

[0009] In one embodiment, the blade assembly is provided with a first magnetic element that is magnetically attracted to the pusher; when the pusher moves relative to the gripping body, the pusher drives the blade assembly to move relative to the gripping body through the magnetic attraction with the first magnetic element, so that the blade assembly extends out of the storage cavity through the vent.

[0010] In one embodiment, the blade assembly is provided with a second magnetic element, which is magnetically attracted to the pusher. The gripping body is provided with a third magnetic element, the third magnetic element and the second magnetic element having the same magnetic poles on their adjacent sides, and the third magnetic element and the second magnetic element repel each other magnetically. When the pusher moves relative to the gripping body, the pusher can overcome the repulsive force between the second magnetic element and the third magnetic element by the magnetic attraction between the pusher and the first magnetic element and the second magnetic element, thereby driving the blade assembly to move relative to the gripping body. This causes the blade assembly to extend out of the storage cavity through the vent. When the blade assembly extends out of the storage cavity, the second magnetic element is misaligned with the third magnetic element in the direction of movement of the blade assembly, so that the repulsive force between the second magnetic element and the third magnetic element maintains the extended state of the blade assembly.

[0011] In one embodiment, the pusher can also overcome the repulsive force between the second and third magnetic elements by magnetic attraction with the first and second magnetic elements, thereby driving the blade assembly to move in the opposite direction relative to the gripping body, so that the blade assembly retracts into the storage cavity and does not protrude from the vent hole. When the blade assembly retracts into the storage cavity, the second magnetic element is misaligned with the third magnetic element in the direction of movement of the blade assembly, so that the repulsive force between the second and third magnetic elements maintains the retracted state of the blade assembly.

[0012] In one embodiment, the pusher is arranged around the outside of the gripping body, there are multiple first magnetic elements disposed at opposite ends of the blade assembly, there are multiple second magnetic elements and multiple third magnetic elements that are aligned with each other, and multiple second magnetic elements are disposed on opposite sides of the blade assembly and located between two adjacent first magnetic elements, and multiple third magnetic elements are disposed on opposite sides of the gripping body.

[0013] In one embodiment, a groove is provided on the outer side of the gripping body. The groove is arranged circumferentially along the outer side of the gripping body, and the length extension direction of the groove is parallel to the length extension direction of the gripping body. The pusher is received in the groove and can move along the groove. When the pusher moves to the limit position, the pusher abuts against the groove wall to prevent the pusher from detaching from the gripping body.

[0014] In one embodiment, the gripping body includes a gripping portion and a protective cover. The end of the gripping portion forms the receiving cavity, and the protective cover is provided with a receiving cavity for receiving the end of the gripping portion. The end of the protective cover forms a vent hole communicating with the receiving cavity, and the protective cover is movably connected to the pusher. The pusher is movable relative to the protective cover, and when the pusher moves, the pusher drives the blade assembly to move relative to the protective cover through magnetic attraction with the blade assembly, so that the blade assembly extends out of the protective cover through the vent hole.

[0015] In one embodiment, the end of the grip portion is provided with a limiting sleeve, the limiting sleeve is received in the receiving cavity, and the limiting sleeve forms the receiving cavity for receiving the blade assembly;

[0016] The limiting sleeve and the protective cover are provided with a protrusion and a groove, respectively. When the limiting sleeve is received in the receiving cavity, the protrusion is received in the groove to prevent the protective cover from detaching from the limiting sleeve. The protective cover can also overcome the elastic force of the protrusion being engaged in the groove to allow the protrusion to detach from the groove, thereby allowing the protective cover to detach from the limiting sleeve.

[0017] In one embodiment, the magnetic nose hair remover further includes a rotating part located between the holding body and the blade assembly. One end of the rotating part is connected to the holding body, and the other end of the rotating part is housed in the blade assembly and circumferentially limited within the blade assembly. The holding body can drive the blades in the blade assembly to rotate via the rotating part, and when the blade assembly moves relative to the holding body, the rotating part can extend so that the end of the rotating part is always housed within the blade assembly.

[0018] In one embodiment, the rotating part includes a first rotating member, a second rotating member, and a spring. The end of the first rotating member is connected to the gripping body. One end of the second rotating member is housed in the first rotating member and is movable relative to the first rotating member. The other end of the second rotating member is housed in the blade assembly and circumferentially limited within the blade assembly. The spring is disposed between the first rotating member and the second rotating member and stores elastic force. When the blade assembly moves relative to the gripping body, the spring releases the elastic force, causing the spring to drive the second rotating member to move relative to the first rotating member so that it is always housed in the blade assembly and circumferentially limited within the blade assembly. At the same time, the gripping body drives the first rotating member to rotate, causing the second rotating member to drive the blade within the blade assembly to rotate.

[0019] In one embodiment, the magnetic nose hair remover further includes a sensor that is in an off state when the blade assembly is housed in the storage cavity, and the holding body is in a standby state when in the off state; and the sensor is in a connected state when the blade assembly extends out of the storage cavity, and the holding body is in a powered-on state when in the connected state, thereby driving the blades in the blade assembly to rotate.

[0020] In one embodiment, the sensor includes a Hall switch and a magnetic element. One of the Hall switch and the magnetic element is disposed on the gripping body, and the other is disposed on the blade assembly. When the blade assembly is received in the storage cavity, the magnetic element senses the Hall switch, causing the Hall switch to be in an open state, and the gripping body is in a stopped state when it is in the open state. When the blade assembly extends out of the storage cavity, the magnetic element moves away from the Hall switch in the direction of movement of the blade assembly, causing the magnetic element to disconnect from the Hall switch, thereby causing the Hall switch to be in a connected state. When it is in the connected state, the gripping body is in an activated state to drive the blade inside the blade assembly to rotate.

[0021] As can be seen from the above technical solutions, the embodiments of the present invention have at least the following advantages and positive effects:

[0022] This invention provides a magnetic nose hair remover. Because the pushing component can extend and retract the blade assembly into the storage cavity, the nose hair remover of this invention does not require a protective cover for storing the blade assembly. Furthermore, users do not need to repeatedly install and remove the protective cover to use the blade assembly, thus simplifying the operation and making it more convenient for users. Additionally, because the grip body has ventilation holes, odors from the blade assembly can be expelled through the ventilation holes when the blade assembly is stored in the storage cavity, and the air inside the storage cavity can also exchange with the outside atmosphere. This prevents bacteria growth and unpleasant odors from developing on the blade assembly, thus solving the problem of unclean and unhygienic blade assembly. 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 1This invention provides a magnetic nose hair remover 1. The magnetic nose hair remover 1 has the function of removing nose hairs. During operation, the user inserts the blade end of the magnetic nose hair remover 1 into the user's nasal cavity. At this time, the blade inside the magnetic nose hair remover 1 rotates to cut the nose hairs, thus achieving the purpose of removing nose hairs. After the nose hairs are completely removed, the blade end of the magnetic nose hair remover 1 is detached from the nasal cavity, and after detachment, the magnetic nose hair remover 1 is closed.

[0041] refer to Figure 2 and Figure 3 The magnetic nose hair remover 1 includes a holding body 10 and a blade assembly 20. The holding body 10 is provided with a storage cavity 101 and a vent 102 communicating with the storage cavity 101. The holding body 10 is also provided with a pusher 103, which can move relative to the holding body 10. The blade assembly 20 is housed in the storage cavity 101 and does not protrude from the vent 102. The blade assembly 20 and the pusher 103 are magnetically attracted.

[0042] Specifically, when using the magnetic nose hair remover 1, the user's hand can hold the holding body 10, and the user's other hand applies external force to the pusher 103. Under the action of external force, the pusher 103 moves relative to the holding body 10. When the pusher 103 moves, the pusher 103 drives the blade assembly 20 to move relative to the holding body 10 through the induced magnetic force between the pusher 103 and the blade assembly 20. This causes the blade assembly 20 to extend out of the storage cavity 101 through the vent 102. The extended part of the blade assembly 20 can be inserted into the nasal cavity. After being inserted into the nasal cavity, the user then activates the holding body 10. The activated holding body 10 drives the blades in the blade assembly 20 to rotate to remove nose hairs, thereby achieving the purpose of removing nose hairs.

[0043] After the nose hairs are removed, the blade assembly 20 is detached from the nasal cavity. After the blade assembly 20 is detached from the nasal cavity, the user applies external force to the pusher 103. Under the action of external force, the pusher 103 moves in the opposite direction relative to the holding body 10. When the pusher 103 moves in the opposite direction, the pusher 103 drives the blade assembly 20 to move in the opposite direction relative to the holding body 10 through the induced magnetic force between the pusher 103 and the blade assembly 20. This causes the blade assembly 20 to retract into the storage cavity 101 and not protrude from the vent 102. After the blade assembly 20 retracts, the user closes the holding body 10. Closing the holding body 10 also stops the blades in the blade assembly 20 from rotating, thus realizing the use of the magnetic nose hair remover 1.

[0044] In this embodiment, the gripping body 10 is cylindrical. Because the gripping body 10 is cylindrical, the user's hand will not experience any bumps or knocks when gripping the gripping body 10, making it convenient for the user to hold. It is also understood that in other embodiments, the external structure of the gripping body 10 may also be a cube, cuboid, etc. Therefore, the present invention does not impose any limitations on the external structure of the gripping body 10.

[0045] In summary, in this invention, since the pushing member 103 can drive the blade assembly 20 to extend and retract into the storage cavity 101, the magnetic nose hair remover 1 of this invention does not require a protective cover to store the blade assembly 20. Furthermore, the user does not need to repeatedly install and remove the protective cover to use the blade assembly 20, thus simplifying the operation and making it more convenient for the user. Additionally, since the holding body 10 is provided with a vent 102, when the blade assembly 20 is housed in the storage cavity 101, any odor from the blade assembly 20 can be expelled through the vent 102, and the air inside the storage cavity 101 can also exchange with the outside atmosphere. This makes it less prone to bacterial growth and unpleasant odors on the blade assembly 20, thus solving the problem of uncleanliness and unsanitary conditions of the blade assembly 20.

[0046] Continue to refer to Figure 3 In one embodiment, a groove 104 is provided on the outer side of the gripping body 10. The groove 104 is circumferentially arranged along the outer side of the gripping body 10, and the length extension direction of the groove 104 is parallel to the length extension direction of the gripping body 10. The pusher 103 is arranged around the outer side of the gripping body 10 and housed within the groove 104. The pusher 103 can move along the groove 104, thereby using the induced magnetic force between itself and the blade assembly 20 to drive the blade assembly 20 to extend and retract into the receiving cavity 101, thus realizing the use of the magnetic nose hair remover 1. At the same time, when the pusher 10 moves to its limit position relative to the gripping body 10, the pusher 10 abuts against the groove wall of the groove 104. At this time, the abutment of the groove wall restricts the pusher 103 from disengaging from the gripping body 10 along the length extension direction of the gripping body 10, thereby achieving relative fixation of the pusher 103 in the length extension direction of the gripping body 10.

[0047] Continue to refer to Figure 3In one embodiment, the gripping body 10 is equipped with a motor 105 and a battery 106. The motor 105 is connected to the blade assembly 20 via an intermediate rotating structure, and the motor 105 is also electrically connected to the battery 106 via a circuit structure. Both the motor 105 and the battery 106 are disposed within the gripping body 10 and arranged sequentially along the length of the gripping body 10, occupying minimal space and thus reducing the overall size of the gripping body 10. When the blade assembly 20 extends out of the storage cavity 101, the battery 106 supplies power to the motor 105 via the circuit structure. Driven by this power, the motor 105 rotates the blades within the blade assembly 20 via the intermediate rotating structure to remove nose hairs. Simultaneously, when the blade assembly 20 retracts into the storage cavity 101, the battery 106 disconnects from the circuit structure, causing the motor 105 to stop rotating, and the blades within the blade assembly 20 to also stop rotating.

[0048] It is understood that in other embodiments, the battery 106 may be omitted, and in this case, an external power source supplies power to the motor 105. Therefore, the present invention does not impose any limitations on the specific configuration of the battery 106.

[0049] Continue to refer to Figure 3 In one embodiment, the gripping body 10 is further provided with a circuit board 107, which is electrically connected to the motor 105 and the battery 106 respectively. The length extension direction of the circuit board 107 is parallel to the length extension direction of the gripping body 10. The circuit board 107 occupies less internal space in the gripping body 10, making the gripping body 10 smaller in size.

[0050] When the blade assembly 20 extends out of the storage cavity 101, the circuit board 107 connects the motor 105 and the battery 106, allowing the battery 106 to supply power to the motor 105 through the circuit board 107. Under the power drive, the motor 105 rotates the blades inside the blade assembly 20. Simultaneously, when the blade assembly 20 retracts into the storage cavity 101, the circuit board 107 disconnects the connection between the motor 105 and the battery 106. After disconnection, the motor 105 loses power and stops, causing the blades of the blade assembly 20 to stop rotating.

[0051] refer to Figure 4 and Figure 5 In one embodiment, the gripping body 10 includes a gripping part 108 and a protective cover 109. The end of the gripping part 108 forms a storage cavity 101. The gripping part 108 is equipped with the motor 105, battery 106 and circuit board 107 mentioned above. The gripping part 108 can also be gripped by the user's hand. The outer side of the protective cover 109 forms a groove 104 for storing the pusher 103. The protective cover 109 is also provided with a receiving cavity 110 for storing the end of the gripping part 108. The end of the protective cover 109 forms a vent hole 102 that communicates with the receiving cavity 110.

[0052] Specifically, during operation, the user holds the grip 108 with one hand and applies external force to the pusher 103 with the other hand. Under the action of the external force, the pusher 103 moves relative to the protective cover 109 along the slide 104. When the pusher 103 moves, it can drive the blade assembly 20 to move relative to the protective cover 109 through the induced magnetic force between the pusher 103 and the blade assembly 20, so that the blade assembly 20 extends out of the protective cover 109 through the vent 102. The extended part of the blade assembly 20 can reach into the nasal cavity. At this time, the blade inside the blade assembly 20 rotates under the drive of the motor 105 to remove nasal hairs.

[0053] After the nose hairs are removed, the user uses the grip 108 to detach the blade assembly 20 from the nasal cavity. After detachment, the user applies external force to the pusher 103. Under the action of the external force, the pusher 103 moves in the opposite direction relative to the protective cover 109 along the slide 104. When the pusher 103 moves in the opposite direction, it drives the blade assembly 20 to retract into the storage cavity 101 through the induced magnetic force between the pusher 103 and the blade assembly 20. At this time, the motor 105 loses power and stops. The stopping of the motor 105 also causes the blades of the blade assembly 20 to stop rotating, thus realizing the use of the magnetic nose hair remover 1.

[0054] In one embodiment, a limiting sleeve 111 is provided at the end of the grip portion 108. The limiting sleeve 111 forms a receiving cavity 101 for receiving the blade assembly 20, and the limiting sleeve 111 is received within the receiving cavity 110, thereby realizing the movable connection between the protective cover 109 and the grip portion 108. It can be understood that in other embodiments, the limiting sleeve 111 can be omitted. In this case, the protective cover 109 can be directly movably connected to the end of the grip portion 108, and the receiving cavity 110 within the protective cover 109 serves as the receiving cavity 101.

[0055] In one embodiment, one of the limiting sleeve 111 and the protective cover 109 is provided with a protrusion 112, and the other is provided with a groove 113. Specifically, in this embodiment, the protrusion 112 is provided on the inner wall of the protective cover 109, and the groove 113 is provided on the outer side of the limiting sleeve 111. It can be understood that in other embodiments, the protrusion 112 is provided on the outer side of the limiting sleeve 111, and the groove 113 is provided on the inner wall of the protective cover 109. Therefore, the present invention does not limit the specific arrangement of the protrusion 112 and the groove 113.

[0056] When the limiting sleeve 111 is received in the receiving cavity 110, the protrusion 112 is received in the groove 113, thereby preventing the protective cover 109 from disengaging from the limiting sleeve 111, thus achieving the installation and fixation of the protective cover 109 and the limiting sleeve 110. Simultaneously, the user can also apply external force to the protective cover 109. Under the action of external force, the protective cover 109 overcomes the elastic force of the protrusion 112 engaging in the groove 113, causing the protrusion 112 to disengage from the groove 113. After the protrusion 112 disengages from the groove 113, the protective cover 109 disengages from the limiting sleeve 111 along its length extension direction, thus achieving the removal of the protective cover 109. After the protective cover 109 is removed, the user can clean the blade assembly 20, or the user can remove the blade assembly 20 from the limiting sleeve 111 to clean the blade assembly 20.

[0057] It should be noted that, in this embodiment, the protrusion 112 is disposed around the inner wall of the protective cover 109 in the circumferential direction, and the groove 113 is disposed around the outer side of the limiting sleeve 111 in the circumferential direction. It can be understood that, in other embodiments, the protrusion 112 and the groove 113 may not be arranged in a ring shape.

[0058] It should be understood that in other embodiments, the protrusion 112 and the groove 113 can be omitted. In this case, the protective cover 109 and the limiting sleeve 111 are connected in a fixed manner to restrict the protective cover 109 from detaching from the limiting sleeve 111. Therefore, the present invention does not limit the specific setting of the protrusion 112 and the groove 113.

[0059] refer to Figure 6 and Figure 7 In one embodiment, the blade assembly 20 is provided with a first magnetic element 201 that is magnetically attracted to the pusher 103. When the pusher 103 moves relative to the protective cover 109, the pusher 103 drives the blade assembly 20 to move relative to the protective cover 109 through the magnetic attraction with the first magnetic element 201, causing the blade assembly 20 to extend out of the protective cover 109 through the vent 102. At the same time, when the pusher 103 moves in the opposite direction relative to the protective cover 109, the pusher 103 can also drive the blade assembly 20 to retract into the storage cavity 101 through the magnetic attraction with the first magnetic element 201, thereby realizing the use of the magnetic nose hair remover 1.

[0060] In this embodiment, there are two first magnetic elements 201, which are disposed at opposite ends of the blade assembly 20. Because there are two first magnetic elements 201, the magnetic attraction between the first magnetic elements 201 and the pusher 103 is stronger, allowing the pusher 103 to better drive the blade assembly 20 to move relative to the protective cover 109. It is also understood that in other embodiments, the number of first magnetic elements 201 can be one or more, and when there are multiple first magnetic elements 201, they are arranged at intervals along the circumference of the blade assembly 20. Therefore, this invention does not limit the number of first magnetic elements 201.

[0061] It is understood that in other embodiments, the first magnetic element 201 is omitted. In this case, the blade assembly 20 is made of magnetically attractive metal material, and the pusher 103 is magnetic. The pusher 103 can magnetically attract the blade assembly 20 and drive the blade assembly 20 to move relative to the protective cover 109 through the magnetic attraction between the pusher 103 and the blade assembly 20, so that the blade assembly 20 can extend and retract into the storage cavity 101.

[0062] It should be noted that in this embodiment, the pusher 103 is magnetic, which gives the pusher 103 a stronger magnetic attraction with the first magnetic element 201 to move the blade assembly 20. It is also understood that in other embodiments, the pusher 103 may not be magnetic; in this case, the pusher 103 may be a magnetically attractive metal material that can magnetically attract the first magnetic element 201.

[0063] refer to Figure 4 and Figure 8 In one embodiment, the blade assembly 20 is provided with a second magnetic element 202, which is magnetically attracted to the pusher 103, and the gripping body 10 is provided with a third magnetic element 114, which is installed on the limiting sleeve 111. The magnetic poles of the third magnetic element 114 and the second magnetic element 202 are the same on the side closest to each other, so that the magnetic forces between the third magnetic element 114 and the second magnetic element 202 repel each other.

[0064] When the pusher 103 moves relative to the protective cover 109, the pusher 103 can overcome the repulsive force between the second magnetic element 202 and the third magnetic element 114 through the magnetic attraction between the pusher 103 and the first magnetic element 201 and the second magnetic element 202, thereby driving the blade assembly 20 to move relative to the protective cover 109, so that the blade assembly 20 extends out of the protective cover 109 through the vent 102. When the blade assembly 20 extends out of the protective cover 109, the second magnetic element 202 is misaligned with the third magnetic element 114 in the direction of movement of the blade assembly 20. After misalignment, the second magnetic element 202 maintains the extended state of the blade assembly 20 through the repulsive force between the second magnetic element 202 and the third magnetic element 114. In this state, the blade assembly 20 continues to remove nasal hairs in the nasal cavity, making it convenient for the user.

[0065] Simultaneously, when the pusher 103 moves in the opposite direction relative to the protective cover 109, the pusher 103 can also overcome the repulsive force between the second magnetic element 202 and the third magnetic element 114 through the magnetic attraction between the pusher 103 and the first magnetic element 201 and the second magnetic element 202, thereby driving the blade assembly 20 to move in the opposite direction relative to the protective cover 109, so that the blade assembly 20 retracts into the receiving cavity 101. When the blade assembly 20 retracts into the receiving cavity 101, the second magnetic element 202 is misaligned with the third magnetic element 114 in the direction of movement of the blade assembly 20. After the misalignment, the second magnetic element 202 maintains the retracted state of the blade assembly 20 through the repulsive force between the second magnetic element 202 and the third magnetic element 114, thereby limiting the movement of the blade assembly 20 relative to the protective cover 109 to extend out of the protective cover 109 in the retracted state, thereby achieving relative fixation of the blade assembly 20 in the retracted state.

[0066] It should be noted that in this embodiment, both the second magnetic element 202 and the third magnetic element 114 are provided in pairs and are aligned with each other. The two second magnetic elements 202 are disposed on opposite sides of the blade assembly 20 and located between the two first magnetic elements 201, while the two third magnetic elements 114 are disposed at opposite ends of the limiting sleeve 111. Since there are two of each second magnetic element 202 and third magnetic element 114, the repulsive force between them is stronger, thereby better maintaining the extended and retracted states of the blade assembly 20. Simultaneously, the presence of two second magnetic elements 202 strengthens the magnetic attraction between them and the pushing member 103, allowing the pushing member 103 to better drive the blade assembly 20 to move relative to the protective cover 109. It is understood that in other embodiments, one or more second magnetic elements 202 and third magnetic elements 114 can be provided; therefore, this invention does not limit the number of second magnetic elements 202 and third magnetic elements 114.

[0067] Continue to refer to Figure 6 In one embodiment, the blade assembly 20 includes a housing 203, a rotating frame 204, and a blade assembly 205. The housing 203 has a nasal hair pore 206 at its end. The housing 203 is housed in the housing cavity 101 and does not protrude from the vent hole 102. A first magnetic element 201 and a second magnetic element 202 are mounted on the housing 203. The rotating frame 204 is housed in the housing 203 and can rotate relative to the housing 203. The rotating frame 204 is connected to the motor 105 through an intermediate rotating structure. The blade assembly 205 is located at the end of the rotating frame 204 away from the motor 105, and the blade edge of the blade assembly 205 abuts against the inner wall of the housing 203.

[0068] When the pusher 103 moves relative to the protective cover 109, the pusher 103 can overcome the repulsive force between the second magnetic element 202 and the third magnetic element 114 through the magnetic attraction between the pusher 103 and the first magnetic element 201 and the second magnetic element 202, thereby driving the outer shell 203 to move relative to the protective cover 109. This allows the outer shell 203 to extend out of the protective cover 109 through the vent 102, and the extended portion of the outer shell 203 can reach into the nasal cavity, allowing nasal hairs to enter the outer shell 203 through the nasal hair pores 206. At this time, the motor 105 is started, and the motor 105 drives the rotating frame 204 to rotate relative to the outer shell 203 through the intermediate rotating structure. The rotation of the rotating frame 204, in turn, drives the blade assembly 205 to rotate to cut the nasal hairs, thereby achieving the purpose of removing nasal hairs. At the same time, when the outer shell 203 extends out of the protective cover 109, the second magnetic element 202 and the third magnetic element 114 are misaligned, so that the repulsive force between the second magnetic element 202 and the third magnetic element 114 maintains the extended state of the outer shell 203.

[0069] When the pusher 103 moves in the opposite direction relative to the protective cover 109, the pusher 103 can also overcome the repulsive force between the second magnetic element 202 and the third magnetic element 114 through the magnetic attraction between the pusher 103 and the first magnetic element 201 and the second magnetic element 202, thereby driving the outer shell 203 to move in the opposite direction relative to the protective cover 109, so that the outer shell 203 retracts into the storage cavity 101. When the outer shell 203 retracts into the storage cavity 101, the motor 105 is in a stopped state, and when it is stopped, the rotating frame 204 also stops rotating. The stopping of the rotating frame 204 also causes the blade assembly 211 to stop rotating, thereby realizing the closing of the magnetic nose hair trimmer 1. At the same time, when the outer shell 203 retracts into the storage cavity 101, the second magnetic element 202 and the third magnetic element 114 are misaligned with each other, so that the repulsive force between the second magnetic element 202 and the third magnetic element 114 maintains the retracted state of the outer shell 203, making it convenient for the user to store the magnetic nose hair trimmer 1.

[0070] It should be noted that in this embodiment, there are multiple nasal hair pores 206. These multiple nasal hair pores 206 are disposed at the end of the outer shell 203 and arranged circumferentially along the outer shell 203. The multiple nasal hair pores 206 are interconnected, allowing nasal hairs to more easily enter the outer shell 203 for removal by the blade assembly 205, thereby facilitating user operation. It is understood that in other embodiments, the nasal hair pore 206 may be a single pore; therefore, this invention does not limit the number of nasal hair pores 206.

[0071] Continue to refer to Figure 6In one embodiment, the blade assembly 205 includes a first blade 207, a second blade 208, and an elastic element 209. The first blade 207 and the second blade 208 are both housed at the end of the rotating frame 204 away from the motor 105 and are movably connected to the end of the rotating frame 204. The first blade 207 and the second blade 208 are located on opposite sides of the rotating frame 204 and are both exposed outside the rotating frame 204. The elastic element 209 is housed at the end of the rotating frame 204 away from the motor 105, and its two ends abut against the first blade 207 and the second blade 208 respectively. The elastic element 208 releases elastic force to drive the cutting edges of the first blade 207 and the second blade 208 to abut against the inner wall of the outer casing 203. When nasal hairs penetrate into the outer casing 203 through the nasal hair pore 206, the rotating frame 204 drives the first blade 207 and the second blade 208 to rotate relative to the outer casing 203 to cut the nasal hairs, thereby achieving the purpose of removing nasal hairs.

[0072] Continue to refer to Figure 3 In one embodiment, the magnetic nose hair remover 1 further includes a rotating part 30, which is disposed between the rotating frame 204 and the holding part 108. One end of the rotating part 30 is connected to the motor 105, and the other end of the rotating part 30 is housed in the rotating frame 204 and circumferentially limited to the rotating frame 204.

[0073] When the pusher 103 moves the outer shell 203 relative to the protective cover 109 to extend the protective cover 109, the length of the rotating part 30 can be extended so that the end of the rotating part 30 is always housed in the rotating frame 204. At this time, the motor 105 is started, so that the motor 105 drives the rotating frame 204 to rotate through the rotating part 30. The rotating frame 204 then drives the first blade 207 and the second blade 208 to rotate to cut the nose hairs that have entered the outer shell 203, thereby achieving the purpose of removing nose hairs.

[0074] At the same time, when the outer shell 203 retracts into the storage cavity 101, the rotating part 30 is stored in the rotating frame 204, and at this time the motor 105 is in a stopped state, so that the rotating part 30 also stops rotating, thereby realizing the closing of the magnetic nose hair remover 1.

[0075] refer to Figure 9 In one embodiment, the rotating part 30 includes a first rotating member 301, a second rotating member 302, and a spring 303. The end of the first rotating member 301 is connected to the motor 105. One end of the second rotating member 302 is housed in the first rotating member 301 and can move relative to the first rotating member 301. The other end of the second rotating member 302 is housed in the rotating frame 204 and is circumferentially limited in the rotating frame 204. The spring 303 is disposed between the first rotating member 301 and the second rotating member 302 and stores elastic force.

[0076] When the pusher 103 moves the outer shell 203 relative to the protective cover 109 to extend the protective cover 109, the spring 303 releases elastic force to move the second rotating member 302 relative to the first rotating member 301, so that the end of the second rotating member 302 is always received in the rotating frame 204 and circumferentially limited in the rotating frame 204. At this time, the motor 105 starts, so that the motor 105 drives the second rotating member 302 to rotate through the first rotating member 301, so that the second rotating member 302 drives the first blade 207 and the second blade to rotate 208 through the rotating frame 204 to cut the nose hair, so as to achieve the purpose of removing nose hair.

[0077] Meanwhile, when the outer shell 203 is housed in the storage cavity 101, the first rotating member 301, the second rotating member 302, and the spring 303 are housed in the rotating frame 204. Under the repulsive force between the second magnetic member 202 and the third magnetic member 114, the spring 303 accumulates elastic force. At this time, the motor 105 is in a stopped state, causing the first rotating member 301 and the second rotating member 302 to stop rotating, which indirectly causes the rotating frame 204, the first blade 207, and the second blade 208 to stop rotating, thereby achieving the closing of the magnetic nose hair remover 1.

[0078] It is understood that the spring 303 can be omitted. In this case, the second rotating member 302 does not need to move relative to the first rotating member 301, and the length between the first rotating member 301 and the second rotating member 302 is sufficient to ensure that the end of the second rotating member 302 is always housed in the rotating frame 204. That is, the first rotating member 301 and the second rotating member 302 are fixedly connected.

[0079] Continue to refer to Figure 4 and Figure 8 In one embodiment, the magnetic nose hair trimmer 1 further includes a sensor 40, which is used to switch the circuit to an off state when the housing 203 is housed in the storage cavity 101. At this time, the battery 106 cannot supply power to the motor 105 through the circuit board 107, and the blade assembly 20 is in a standby state. The sensor 40 is also used to switch the circuit to an on state when the housing 203 extends out of the storage cavity 101. At this time, the battery 106 can supply power to the motor 105 through the circuit board 107, and the blade assembly 20 is in a powered-on state.

[0080] In one embodiment, the sensor 40 includes a Hall switch 401 and a magnetic element 402, one of which is disposed on the grip body 10, and the other is disposed on the blade assembly 20. Specifically, in this embodiment, the Hall switch 401 is disposed on the circuit board 107, and the magnetic element 402 is disposed on the housing 203. It can be understood that in other embodiments, the Hall switch 401 is disposed on the housing 206, and the magnetic element 402 is disposed on the circuit board 107. Therefore, the present invention does not limit the arrangement of the Hall switch 401 and the magnetic element 402.

[0081] When the outer casing 203 retracts into the storage cavity 101, the magnetic component 402 senses the Hall switch 401, causing the Hall switch 401 to be in the off state. In the off state, the battery 106 cannot supply power to the motor 105 through the circuit board 107, causing the motor 105 to stop. Simultaneously, when the outer casing 203 extends out of the storage cavity 101, the magnetic component 402 senses the Hall switch 401 to disconnect, causing the Hall switch 401 to be in the connected state. In the connected state, the battery 106 can supply power to the motor 105 through the circuit board 107, causing the motor 105 to start and rotate. The rotation of the motor 105, in turn, drives the first blade 207 and the second blade 208 to rotate through the rotating frame 201, thus realizing the use of the magnetic nose hair remover 1.

[0082] It should be noted that in other embodiments, the sensor 40 may not use the Hall switch 401 to realize the closing and opening of the circuit. For example, the sensor 40 may use a magnetic reed switch or a contact push switch. The working principle of the magnetic reed switch and the Hall switch 401 is the same, so it will not be described in detail here.

[0083] 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.
