Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to an electric nasal hair brush. Background Technology

[0002] The nasal cavity is the gateway to the respiratory tract, and the nasal vestibule is the "first line of defense" of the nasal cavity. The nasal hairs and skin folds in this area can filter dust, pollen, pathogens and other pollutants from the air. However, the humid environment here can also easily breed bacteria. An electric nasal brush is a device that can scientifically clean the nasal vestibule to avoid the accumulation of dirt and bacteria, maintain the cleanliness and filtering function of the nasal cavity, prevent infection and protect respiratory health.

[0003] However, existing electric nose brushes have the following drawbacks: the softness and hardness of the bristles on electric nose brushes are usually limited. Due to the lack of bristles that can be selected according to the user's needs, users can only change to different electric nose brushes when they want to use different softness and hardness bristles, which makes the scope of application of general electric nose brushes relatively small. Utility Model Content

[0004] This utility model aims to provide an electric nose hair brush, mainly to solve the technical problem that the existing technology lacks brushes with different softness and hardness according to the user's needs. As a result, when users want to use brushes with different softness and hardness, they can only change to different electric nose hair brushes, which limits the applicability of general electric nose hair brushes.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An electric nose brush includes a control handle, a motor fixedly connected to the inner wall of the control handle, and a transmission rod fixedly connected to the output shaft of the motor via a coupling. A groove communicating with the top end of the transmission rod is formed on the outer wall of the transmission rod, and several embedding grooves communicating with the groove are formed on the outer wall of the transmission rod. A first brush ring, a second brush ring, and a third brush ring are slidably connected from bottom to top inside the groove. A movable plate is slidably disposed inside one end of the transmission rod, and a positioning groove is formed through the outer side of the movable plate. A positioning block is adapted to the positioning groove. A snap-fit ​​plate is fixedly connected to one side of the movable plate, passing through one side of the transmission rod. A rubber cover is provided on one side of the transmission rod, and a snap-fit ​​groove adapted to the snap-fit ​​plate is formed through the surface of the rubber cover. A movable ring is slidably connected to the outer wall of the transmission rod near the inside of the groove, and an embedding block adapted to the inside of the embedding groove is fixedly connected to the inner wall of the movable ring.

[0007] The working principle and beneficial effects of this utility model:

[0008] 1. Working Principle: The snap-fit ​​plate separates from the snap-fit ​​groove, allowing the user to easily pull the rubber cover away from one end of the transmission rod. This facilitates the retraction of the two movable plates into the movable groove, thus removing the restriction on the third brush ring. The user can then select any one of the first, second, and third brush rings. One of these rings is left on the outer wall of the transmission rod, while the others slide out. The movable plates are then reset. The positioning block at one end of the remaining brush ring is then embedded in the positioning groove. By moving the top of the movable ring to the bottom of the brush ring and rotating it clockwise, the movable ring causes the embedded block to rotate into the embedding groove, thus restricting the position of the movable ring and clamping and fixing the selected brush ring onto the transmission rod for user convenience.

[0009] 2. Beneficial effects:

[0010] (1) By separating the snap-fit ​​plate from the snap-fit ​​groove, it is convenient for the user to pull the rubber cover away from one end of the transmission rod, so that the two moving plates can be retracted into the moving groove, thereby removing the restriction on the third brush ring. This allows the user to select the first, second, and third brush rings according to the required brush hardness. Then, leave any one of the first, second, and third brush rings on the outer wall of the transmission rod, and let the rest slide out of the transmission rod. Then, snap the snap-fit ​​groove on one side of the rubber cover back into the snap-fit ​​plate to restrict the position of the moving plate. Then, embed the positioning block at one end of the remaining brush ring into the positioning groove, and move the top of the moving ring to the bottom of the brush ring, and then rotate the moving ring clockwise so that the moving ring drives the embedding block into the embedding groove. At this time, the embedding block drives the rubber pad to make tight contact with the snap-fit ​​groove, thereby restricting the position of the moving ring and clamping and fixing the selected brush ring on the transmission rod for user convenience.

[0011] Preferably, the outer wall brush hardness of the first brush ring, the second brush ring, and the third brush ring is soft, moderate, and hard, respectively; allowing the user to choose any one of the first brush ring, the second brush ring, and the third brush ring according to their desired brush hardness.

[0012] Preferably, the outer wall of the control grip is connected to a buckle sleeve via a connecting rope. The inside of the buckle sleeve is adapted to the first brush ring, the second brush ring, and the third brush ring, so that the buckle sleeve can be fitted onto the outside of the first brush ring, the second brush ring, and the third brush ring, thereby preventing the first brush ring, the second brush ring, and the third brush ring from being contaminated.

[0013] Preferably, one end of the transmission rod has a moving groove, and one side of the transmission rod has a guide groove that connects to the moving groove. Two moving plates are provided, and the two moving plates are slidably connected inside the two moving grooves respectively. The outer wall of the snap-fit ​​plate passes through the inside of the guide groove. When the third brush ring drives the positioning block to separate from the positioning groove, the two moving plates are pushed into the moving groove, so that the moving plates are retracted into the moving groove. At this time, the moving plates drive the snap-fit ​​plate to move inside the guide groove, thereby releasing the restriction on the third brush ring.

[0014] Preferably, a drawstring passing through the guide groove is fixedly connected to the inner wall of the moving groove, one side of the rubber cover is bonded to one end of the drawstring, two snap-fit ​​grooves are provided, and the snap-fit ​​plate and the snap-fit ​​groove are detachably snap-fitted; pulling the rubber cover towards the top of the transmission rod causes the rubber cover to drive the snap-fit ​​groove and the snap-fit ​​plate to separate, at which time the drawstring is stretched, thereby releasing the restriction on the snap-fit ​​plate.

[0015] Preferably, there are two slide grooves and two sets of embedding grooves. The two sets of embedding grooves are arranged in a symmetrical ring array. Several embedding grooves in each set are arranged in a linear array at equal intervals along the radial direction of the two slide grooves. Two sliders are fixedly connected to the inner walls of the first brush ring, the second brush ring, and the sliders are adapted to the slide grooves. Positioning blocks are fixedly connected to the top of the first brush ring, the second brush ring, and the third brush ring. Splicing grooves are opened at the bottom of the first brush ring, the second brush ring, and the third brush ring. The positioning blocks are adapted to the splicing grooves. When one of the first brush ring, the second brush ring, and the third brush ring remains on the outer wall of the transmission rod, the other two brush rings can be driven by the adjacent brush rings to engage with the positioning blocks and splicing grooves, thereby facilitating the combined storage of adjacent brush rings.

[0016] Preferably, there are two embedding blocks arranged in a circular array. Rubber pads are glued to the top and bottom of each embedding block near the inside of the embedding groove. When the top of the moving ring moves to the bottom of the brush ring, the embedding block is aligned with the uppermost embedding groove. Rotating the moving ring clockwise causes the moving ring to drive the embedding block into the embedding groove. At this time, the embedding block causes the rubber pad to make tight contact with the locking groove, thereby restricting the position of the moving ring. Attached Figure Description

[0027] Please see Figures 1-8As shown, an electric nose brush includes a control handle 1. A motor 3 is fixedly connected to the inner wall of the control handle 1. The output shaft of the motor 3 is fixedly connected to a transmission rod 4 via a coupling. A groove 15 communicating with the top end of the transmission rod 4 is formed on the outer wall of the transmission rod 4. Several embedded grooves 16 communicating with the groove 15 are formed on the outer wall of the transmission rod 4. A first brush ring 5, a second brush ring 6, and a third brush ring 7 are slidably connected from bottom to top inside the groove 15. A positioning block 18 is fixedly connected to the top end of each of the first brush ring 5, the second brush ring 6, and the third brush ring 7. A splicing groove 19 is formed at the bottom end of each of the first brush ring 5, the second brush ring 6, and the third brush ring 7. The positioning block 18 is adapted to the splicing groove 19. The softness and hardness of the brushes on the outer walls of the first brush ring 5, the second brush ring 6, and the third brush ring 7 are respectively... To achieve soft, moderate, and firm pressure, the outer wall of the control handle 1 is connected to a buckle sleeve 2 via a connecting rope. The buckle sleeve 2 is adapted to the first brush ring 5, the second brush ring 6, and the third brush ring 7. There are two slide grooves 15 and two sets of embedding grooves 16. The two sets of embedding grooves 16 are arranged in a circular array symmetrically. Several embedding grooves 16 in the two sets are arranged in a linear array equidistantly along the radial direction of the two slide grooves 15. Two sliders 17 are fixedly connected to the inner walls of the first brush ring 5, the second brush ring 6, and the third brush ring 7, and the sliders 17 are adapted to the slide grooves 15. By controlling the handle 1 to start the motor 3, the output end of the motor 3 drives the transmission rod 4 to rotate counterclockwise, so that the user can use any one of the first brush ring 5, the second brush ring 6, and the third brush ring 7 to clean nose hair.

[0028] A movable plate 10 is slidably mounted inside one end of the transmission rod 4. A positioning groove 11 is formed through the outer side of the movable plate 10. A positioning block 18 is adapted to the positioning groove 11. A snap-fit ​​plate 12 is fixedly connected to one side of the movable plate 10, passing through one side of the transmission rod 4. A rubber cover 14 is provided on one side of the transmission rod 4. A snap-fit ​​groove 23 adapted to the snap-fit ​​plate 12 is formed through the surface of the rubber cover 14. A movable groove 8 is formed at one end of the transmission rod 4. A guide groove 9 communicating with the movable groove 8 is formed on one side of the transmission rod 4. Two movable plates 10 are provided. The two sliding connections are respectively connected inside the two moving slots 8. The outer wall of the snap-fit ​​plate 12 passes through the inside of the guide slot 9. The inner wall of the moving slot 8 is fixedly connected to the drawstring 13 that passes through the guide slot 9. One side of the rubber cover 14 is bonded to one end of the drawstring 13. Two snap-fit ​​slots 23 are opened through the outer side of the rubber cover 14. The snap-fit ​​plate 12 and the snap-fit ​​slots 23 are detachable snap-fit ​​settings. Pull the rubber cover 14 towards the top of the transmission rod 4 so that the rubber cover 14 drives the snap-fit ​​slots 23 to separate from the snap-fit ​​plate 12. At this time, the drawstring 13 is stretched, thereby releasing the restriction on the snap-fit ​​plate 12.

[0029] A movable ring 20 is slidably connected to the outer wall of the transmission rod 4 near the inside of the slide groove 15. An insert block 21, adapted to the inside of the insert groove 16, is fixedly connected to the inner wall of the movable ring 20. Two insert blocks 21 are arranged symmetrically in a circular array. Rubber pads 22 are respectively adhered to the top and bottom ends of the insert blocks 21 near the inside of the insert groove 16. Rotating the movable ring 20 counterclockwise causes the insert blocks 21 to separate from the insert groove 16 and rotate into the slide groove 15. Under the weight of the first brush ring 5, the second brush ring 6, and the third brush ring 7, the insert blocks 21 on the inner wall of the movable ring 20 move to the bottom of the slide groove 15. At this time, the third brush ring 7 causes the positioning block 18 to separate from the positioning groove 11 and move into the movable groove 8. The two moving plates 10 are pushed internally, causing them to retract into the moving groove 8. At this time, the moving plates 10 drive the snap-fit ​​plate 12 to move inside the guide groove 9, thereby releasing the restriction on the third brush ring 7. This allows the first brush ring 5, the second brush ring 6, and the third brush ring 7 to drive the slider 17 to move upward inside the sliding groove 15, so that the first brush ring 5, the second brush ring 6, and the third brush ring 7 can be separated from the transmission rod 4. At this time, the adjacent brush rings drive the positioning block 18 to separate from the splicing groove 19, allowing the user to select the first brush ring 5, the second brush ring 6, and the third brush ring 7 according to the required brush hardness. Then, any one of the brush rings selected by the user is left on the outer wall of the transmission rod 4.

[0030] The two movable plates 10 are pulled out of the movable groove 8 again, and the snap-fit ​​groove 23 on one side of the rubber cover 14 is snapped back into the snap-fit ​​plate 12 to restrict the position of the movable plates 10. The remaining brush ring is pushed upward so that the positioning block 18 at one end of the brush ring is embedded in the positioning groove 11. Then the movable ring 20 is pushed upward so that the movable ring 20 drives the embedded block 21 to move inside the slide groove 15. When the top of the movable ring 20 moves to the bottom of the brush ring, the embedded block 21 is aligned with the uppermost embedded groove 16. The movable ring 20 is rotated clockwise so that the movable ring 20 drives the embedded block 21 to rotate into the embedded groove 16. At this time, the embedded block 21 drives the rubber pad 22 to make tight contact with the snap-fit ​​groove 23 to restrict the position of the movable ring 20, thereby clamping and fixing the selected brush ring on the transmission rod 4.

[0031] As described above, the specific implementation of this utility model is as follows: Pull the rubber cover 14 towards the top of the transmission rod 4, causing the rubber cover 14 to separate the locking groove 23 from the locking plate 12. At this time, the coiling rope 13 is stretched, thereby releasing the restriction on the locking plate 12. Then, rotate the moving ring 20 counterclockwise, causing the moving ring 20 to separate the embedded block 21 from the embedded groove 16 and rotate into the sliding groove 15. Under the weight of the first brush ring 5, the second brush ring 6, and the third brush ring 7, the embedded block 21 on the inner wall of the moving ring 20 moves to the bottom of the sliding groove 15. At this time, the third brush ring 7 causes the positioning block 18 to separate from the positioning groove 11, pushing the two moving plates 10 into the moving groove 8, causing the moving... The plate 10 retracts into the moving groove 8. At this time, the moving plate 10 drives the snap-fit ​​plate 12 to move inside the guide groove 9, thereby releasing the restriction on the third brush ring 7. This allows the first brush ring 5, the second brush ring 6, and the third brush ring 7 to drive the slider 17 to move upward inside the sliding groove 15, so that the first brush ring 5, the second brush ring 6, and the third brush ring 7 can be separated from the transmission rod 4. At this time, the adjacent brush ring drives the positioning block 18 to separate from the splicing groove 19, making it convenient for the user to select the first brush ring 5, the second brush ring 6, and the third brush ring 7 according to the required brush hardness. Then, any one of the brush rings selected by the user is left on the outer wall of the transmission rod 4.

[0032] Subsequently, the two movable plates 10 are pulled out of the movable groove 8 again. Due to the reaction force of the coiling rope 13, the locking groove 23 on one side of the rubber cover 14 is re-engaged with the locking plate 12, thereby restricting the position of the movable plate 10. The reset rubber cover 14 protects the guide groove 9 at one end of the transmission rod 4, preventing debris from entering the movable groove 8 through the guide groove 9. The remaining brush ring is pushed upward, causing the positioning block 18 at one end of the brush ring to embed into the positioning groove 11. Then, the movable ring 20 is pushed upward, causing the movable ring 20 to drive the embedded block 21 to move inside the slide groove 15. When the top of the moving ring 20 moves to the bottom of the brush ring, the inserting block 21 aligns with the uppermost inserting groove 16. Rotating the moving ring 20 clockwise causes the moving ring 20 to drive the inserting block 21 into the inserting groove 16. At this time, the inserting block 21 causes the rubber pad 22 to come into close contact with the locking groove 23, thereby restricting the position of the moving ring 20 and clamping and fixing the selected brush ring on the transmission rod 4. By controlling the handle 1 to start the motor 3, the output end of the motor 3 drives the transmission rod 4 to rotate counterclockwise, which makes it convenient for the user to use the remaining brush ring to clean nose hairs.
