Description

Technical Field

[0001] This invention relates to the field of mirror technology, and in particular to a mirror and a cabinet using the same. Background Technology

[0002] Some existing mirrors have a blowing mechanism, allowing users to dry their faces faster while looking in the mirror. Some cabinets also use mirrors with blowing mechanisms, but because the air inlet and outlet of the mirror's air duct are always open, the inside of the cabinet is connected to the external environment through the air duct. This allows dust, moisture, insects, and other contaminants from the outside environment to enter the cabinet, affecting the hygiene of the stored items inside. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the aforementioned technical problems in the related art. To this end, the present invention proposes a mirror.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] The present invention also proposes a cabinet having the aforementioned mirror.

[0006] A mirror according to a first aspect of the present invention comprises:

[0007] A housing, wherein a first air duct and a first mounting base are provided on the housing;

[0008] A fan, which is mounted on the housing, is used to supply air to the first air duct;

[0009] The mirror body is mounted on the first mounting base;

[0010] A second mounting base is movably mounted on the housing. A second air duct and an air outlet for supplying air outward through the second air duct are defined between the second mounting base and the first mounting base. The first air duct communicates with the second air duct. The second mounting base is movable relative to the first mounting base between opening and closing the air outlet.

[0011] The mirror according to the embodiments of the present invention has at least the following beneficial effects: the opening and closing of the air outlet is controllable, which can effectively prevent external dust, water vapor or mosquitoes from entering the second air duct and the first air duct through the air outlet when it is not in use due to the air outlet being in an open state for a long time.

[0012] According to some embodiments of the present invention, the first mounting base is movably mounted on the housing, and the forward and reverse movement directions of the first mounting base are consistent with the forward and reverse movement directions of the second mounting base. When the first mounting base and the second mounting base move forward, the first mounting base and the second mounting base gradually shift in the movement direction so that the air outlet gradually opens. When the first mounting base and the second mounting base move in opposite directions, the first mounting base and the second mounting base can move to abut against each other to close the air outlet.

[0013] According to some embodiments of the present invention, the first mounting base and the second mounting base are coaxially arranged, the second air duct extends around the first mounting base in an annular shape, and the air outlet is formed between the ends of the first mounting base and the ends of the second mounting base surrounding the mirror body.

[0014] According to some embodiments of the present invention, the first mounting base has a first end face, and a boss is provided on the first end face surrounding the central axis of the first mounting base. The boss divides the first end face into a first region and a second region. The first region is closer to the central axis of the first mounting base than the second region. The mirror body is mounted on the first region. One end of the second mounting base is provided with a protruding edge extending in the direction of its central axis. The protruding edge is axially opposite to the second region. The protruding edge, the second region, and the boss together form the air outlet. When the first mounting base and the second mounting base move relative to each other, the protruding edge moves closer to or further away from the second region.

[0015] According to some embodiments of the present invention, the second mounting base is provided with an inclined platform, which is inclinedly arranged around the central axis of the second mounting base and facing the air outlet. The inclined platform extends inclinedly from the inner wall of the second mounting base toward the inner edge near the protruding edge. When the second mounting base moves in the direction of opening the air outlet, the second mounting base can move to a position where at least a portion of the inclined platform is higher than the maximum protrusion height of the protrusion along the protrusion direction of the protrusion.

[0016] According to some embodiments of the present invention, a drive mechanism is further included, which is connected between the first mounting base and the second mounting base to drive the first mounting base and the second mounting base to move in the same direction relative to the housing and simultaneously drive the first mounting base and the second mounting base to move relative to each other.

[0017] According to some embodiments of the present invention, the driving mechanism includes a first movable seat, a second movable seat, a first gear ring, a second gear ring, a motor and a drive wheel. The first movable seat and the second movable seat are movably but non-rotatably mounted on the housing. The first gear ring and the second gear ring are rotatably but non-movably mounted on the housing. The mirror body or the second mounting seat is connected to the first movable seat, and the first mounting seat is connected to the second movable seat.

[0018] The first gear ring is sleeved on the first movable seat and the two are threaded together. The second movable seat is sleeved on the second gear ring and the two are threaded together. The second gear ring is spaced around the first gear ring. The drive wheel is connected to the motor and meshes between the first gear ring and the second gear ring. When the motor drives the drive wheel to rotate, the drive wheel drives the first gear ring and the second gear ring to rotate in opposite directions, thereby driving the first movable seat and the second movable seat to move relative to each other in the same direction.

[0019] According to some embodiments of the present invention, the first movable seat is provided with a first external thread, the inner side of the first gear ring is provided with a first internal thread that connects with the first external thread, and the outer side of the first gear ring is provided with a first tooth surface.

[0020] The inner side of the second gear ring is provided with a second tooth surface, the outer side of the second gear ring is provided with a second external thread, and the inner side of the second movable seat is provided with a second internal thread that connects with the second external thread.

[0021] The outer diameter of the first gear ring is smaller than the inner diameter of the second gear ring. The outer side of the drive wheel is provided with a third tooth surface. The drive wheel is located between the first gear ring and the second gear ring and meshes with the first tooth surface and the second tooth surface.

[0022] The number of teeth on the first tooth surface is less than the number of teeth on the second tooth surface, and the direction of rotation of the first external thread is opposite to that of the second external thread.

[0023] According to some embodiments of the present invention, the housing has a first sidewall and a second sidewall in the direction in which the first mounting base and the second moving component move relative to each other. The first mounting base and the second mounting base are mounted in the housing. The first mounting base and the second mounting base are telescopically movable through the first sidewall to the inside and outside of the housing. The first air duct is formed in the housing. The air inlet of the first air duct is opened on the second sidewall. The fan is mounted on the first air duct.

[0024] The cabinet according to a second aspect of the present invention includes a mirror.

[0025] The cabinet according to the embodiments of the present invention has at least the following beneficial effects: the opening and closing of the air outlet is controllable, which can effectively prevent external dust, moisture or insects from entering the cabinet through the air outlet, the second air duct or the first air duct when the air outlet is not in use due to being in an open state for a long time.

Detailed Implementation

[0043] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0044] The present invention relates to a mirror, comprising a housing 100, a fan 200, a mirror body 400, and a second mounting base 500.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the exterior of the housing 100 can be assembled from a front housing 120 and a rear housing 130. A first air duct 110 is defined between the front housing 120 and the rear housing 130. The first air duct 110 can also be installed as an independent component within the housing 100. A fan 200 is installed on the housing 100, either inside the first air duct 110 or at the air inlet 111 of the first air duct 110. One, two, or more fans 200 can be provided. The fan 200 draws air from the external environment into the first air duct 110. A first mounting base 300 is provided on the housing 100. The first mounting base 300 can be installed as an independent component on the housing 100 or can be integrally formed on the housing 100. A second mounting base 500 is movably installed on the housing 100. When the second mounting base 500 moves relative to the housing 100, it also moves relative to the first mounting base 300. A mirror body 400 is mounted on a first mounting base 300. The mirror body 400 can be a plane mirror, a convex mirror, a concave mirror, or a mirror body 400 with a variable convex-concave shape. A second air duct 600 and an air outlet 610 are defined between the first mounting base 300 and the second mounting base 500. The air outlet 610 is used to supply air from the second air duct 600 to the external environment. The second air duct 600 is connected to the first air duct 110. The opening orientation of the air outlet 610 can be set to be consistent with the orientation of the mirror body 400. In this embodiment, as shown... Figure 4 and Figure 5 As shown, initially, the fan 200 is in the off state, and the second mounting base 500 is positioned relative to the first mounting base 300 with the air outlet 610 closed. At this time, the first air duct 110 and the second air duct 600 cannot connect to the external environment through the air outlet 610. Figure 6As shown in the diagram, in the direction indicated, the second mounting base 500 moves to the right relative to the first mounting base 300, the air outlet 610 is gradually opened, the fan 200 starts, and the fan 200 draws air from the external environment into the first air duct 110. The airflow flows along the first air duct 110 and the second air duct 600, and finally blows out to the right from the air outlet 610. The mirror body 400 is mounted on the right side of the first mounting base 300. During the use of the mirror body 400, the user can control the start of the fan 200 and the movement of the second mounting base 500 to dry the face. When the drying function is not needed, the second mounting base 500 retracts to the left into the housing 100, and the air outlet 610 is closed. In practical applications, the mirror can be used on a cabinet. The mirror can be embedded and fixed to the cabinet door or cabinet panel through the housing 100, with the mirror body 400 and the air outlet 610 facing outwards. The air inlet 111 of the first air duct 110 can be set to face inwards towards the cabinet. When in use, the second mounting base 500 can be moved to protrude outside the cabinet door. When not in use, the second mounting base 500 retracts into the housing 100 and does not protrude from the cabinet door. The first mounting base 300 is also in the housing 100 and does not protrude from the cabinet door, reducing space occupation. It can also effectively prevent external dust, moisture or insects from entering the cabinet through the air outlet 610, the second air duct 600, and the first air duct 110 when the air outlet 610 is not in use due to being in an open state for a long time.

[0046] In one embodiment, such as Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the first mounting base 300 is movably mounted on the housing 100. Both the first mounting base 300 and the second mounting base 500 are capable of moving forward and backward relative to the housing 100. The forward movement of the first mounting base 300 and the forward movement of the second mounting base 500 are in the same direction, and the reverse movement of the first mounting base 300 and the reverse movement of the second mounting base 500 are in the same direction. In this embodiment, the forward movement of the first mounting base 300 and the forward movement of the second mounting base 500 are in the right direction, and the reverse movement of the first mounting base 300 and the reverse movement of the second mounting base 500 are in the left direction. When the first mounting base 300 and the second mounting base 500 move in the forward direction, they gradually shift out of alignment, causing the air outlet 610 to gradually open. Specifically, the rightward movement of the first mounting base 300 differs from that of the second mounting base 500. For example, if the second mounting base 500 moves 10cm to the right, the first mounting base 300 moves 9cm to the right, creating a 1cm misalignment on the right side of both, thus opening the air outlet 610. The size of the air outlet 610 can be controlled by adjusting the relative movement of the first mounting base 300 and the second mounting base 500. Without changing the power of the fan 200, altering the size of the air outlet 610 changes the airflow speed, thus satisfying different drying needs of the user. Meanwhile, with the distance between the human body and the housing 100 remaining constant, the relative distance between the mirror body 400 and the air outlet 610 and the user can be changed by controlling the rightward movement of the first mounting base 300 and the second mounting base 500 relative to the housing 100. This satisfies the different viewing distance and drying distance requirements of various users. When the first mounting base 300 and the second mounting base 500 move in opposite directions, they move to the left. When the first mounting base 300 and the second mounting base 500 move to abut against each other, the air outlet 610 closes.

[0047] Air outlets 610 are distributed around the periphery of the first mounting base 300. There can be one, two, or more air outlets 610 spaced apart along the circumference of the first mounting base 300. In one embodiment, such as... Figure 3 and Figure 8As shown, the first mounting base 300 and the second mounting base 500 are coaxially arranged, and the second air duct 600 extends in a ring around the first mounting base 300. In the direction shown, an air outlet 610 is formed between the right ends of the first mounting base 300 and the right ends of the second mounting base 500, and this air outlet 610 is arranged in a ring around the mirror body 400. When the user uses the drying function, the air outlet 610 can blow air from all sides around the mirror body 400 towards the user, achieving a wide-range airflow effect. After the second mounting base 500 is moved back to its rightward position, the entire ring-shaped air outlet 610 is closed.

[0048] In one embodiment, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10 As shown, the first mounting base 300 has a first end face 310. In the illustrated direction, the first end face 310 is located on the right side of the first mounting base 300. A boss 320 is provided on the first end face 310, surrounding the central axis of the first mounting base 300. The central axis of the first mounting base 300 is horizontally oriented left-right, and the boss 320 protrudes to the right. The boss 320 divides the first end face 310 into a first region 311 and a second region 312, that is, the first region 311 and the second region 312 are radially distributed along the first mounting base 300. The first region 311 is closer to the central axis of the first mounting base 300 than the second region 312. The lens body 400 is mounted on the first region 311, and the boss 320 surrounds the lens body 400. The second mounting base 500 is annularly surrounding the first mounting base 300. The right end of the second mounting base 500 has a protruding edge 510 extending towards its central axis. The protruding edge 510 is axially opposite to the second region 312, meaning at least a portion of the second region 312 is laterally opposite to at least a portion of the protruding edge 510. The protruding edge 510, the second region 312, and the boss 320 together form an air outlet 610. When the first mounting base 300 and the second mounting base 500 move relative to each other, the protruding edge 510 moves closer to or further away from the second region 312. When the second mounting base 500 moves to the right relative to the first mounting base 300, the protruding edge 510 moves further to the right relative to the second region 312, and the air outlet 610 gradually opens. When the second mounting base 500 moves to the left relative to the first mounting base 300, the protruding edge 510 gradually moves to the left relative to the second region 312. When the protruding edge 510 abuts against the second region 312, the air outlet 610 closes.

[0049] Furthermore, such as Figure 6 , Figure 7 , Figure 8 and Figure 11As shown, the second mounting base 500 has a ramp 520, which is inclined around the central axis of the second mounting base 500 and faces the air outlet 610. The ramp 520 extends inclinedly from the inner wall of the second mounting base 500 towards the inner edge of the protruding edge 510. The inner edge of the protruding edge 510 is the side of the protruding edge 510 near the protruding platform 320. The side of the ramp 520 away from the protruding edge 510 is further away from the central axis of the second mounting base 500 than the side of the ramp 520 near the protruding edge 510. Figure 6 As shown, when the second mounting base 500 moves to the right along the direction of opening the air outlet 610, the air outlet 610 gradually opens. When the inclined platform 520 moves with the second mounting base 500 to the rightmost range where it does not yet protrude to the right from the boss 320, that is, when the circumferential outer wall of the boss 320 and the circumferential inner wall of the protrusion 510 are radially opposite each other, the airflow flows along the second air duct 600 and blows towards the inclined platform 520. The inclined platform 520 changes the airflow direction, causing the airflow to flow radially toward the boss 320 from the second mounting base 500. After the airflow impacts the boss 320, the circumferential outer wall of the boss 320 and the circumferential inner wall of the protrusion 510 cooperate to guide the airflow to blow to the right along the axial direction of the second mounting base 500. As the second mounting base 500 continues to move to the right, it can move until at least a portion of the ramp (520) is higher than the maximum protrusion height of the boss 320 along the protrusion direction of the boss 320. The protrusion height direction of the boss 320 is to the right, that is, the ramp 520 moves with the second mounting base 500 to the rightmost part of the protruding boss 320. Figure 7 As shown, at this time, the circumferential inner wall of the protrusion 510 and the circumferential outer wall of the protrusion 320 are misaligned in the left and right directions. After the airflow of the second air duct 600 impacts the inclined platform 520, the inclined platform 520 guides the airflow to change direction. The airflow flows towards the central axis of the second mounting base 500. At this time, the airflow will accelerate the gas flow on the surface of the mirror body 400, thereby having the effect of drying and defogging the surface of the mirror body 400. When defogging, the airflow in the circumferential direction of the air outlet 610 converges towards the center of the mirror body 400. After converging, it continues to flow to the right, which can also serve the function of drying the user's face.

[0050] In one embodiment, a drive mechanism is also included, connected between the first mounting base 300 and the second mounting base 500, to drive the first mounting base 300 and the second mounting base 500 to move in the same direction relative to the housing 100, thereby changing the distance and position of the mirror body 400 and the air outlet 610 relative to the human body. The drive mechanism can also simultaneously drive the first mounting base 300 and the second mounting base 500 to move relative to each other, thereby changing the opening size of the air outlet 610 and, in conjunction with the ramp 520, changing the airflow direction. The drive mechanism can use different servo motors to control the movement of the first mounting base 300 and the second mounting base 500 respectively.

[0051] In this embodiment, as Figure 2 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, the drive mechanism includes a first movable seat 710, a second movable seat 720, a first gear ring 730, a second gear ring 740, a motor 750, and a drive wheel 760. The first movable seat 710 and the second movable seat 720 are movably but non-rotatably mounted on the housing 100. Alternatively, a plurality of first guide posts 140 may be provided within the housing 100. The first guide posts 140 extend along the moving direction of the first movable seat 710 and pass through the first movable seat 710. The plurality of first guide posts 140 cooperate to restrict the rotation of the first movable seat 710 relative to the housing 100, while the first movable seat 710 can move along the first guide posts 140. Multiple second guide posts 150 are provided inside the housing 100. The second guide posts 150 extend along the moving direction of the second movable seat 720 and pass through the second movable seat 720. The multiple second guide posts 150 cooperate to restrict the rotation of the second movable seat 720 relative to the housing 100, while the second movable seat 720 can move along the second guide posts 150. The first gear ring 730 and the second gear ring 740 are rotatably but immovably mounted on the housing 100. For example, a first fixing ring 810 is installed in the housing 100. The first fixing ring 810 and the housing 100 define a first limiting groove 811 that surrounds the central axis of the first gear ring 730. The first gear ring 730 is provided with a first protruding edge 733, which engages in the first limiting groove 811, thereby allowing the first gear ring 730 to rotate about the axial direction but not to move along the axial direction. A second retaining ring 820 is installed in the housing 100. A second limiting groove 821, surrounding the central axis of the second gear ring 740, is defined between the second retaining ring 820 and the housing 100. A second protruding edge 743 is provided on the second gear ring 740, and the second protruding edge 743 engages in the second limiting groove 821, thereby allowing the second gear ring 740 to rotate about the axial direction but not to move axially. The mirror body 400 or the second mounting base 500 is connected to the first movable base 710, and the first mounting base 300 is connected to the second movable base 720. A first gear ring 730 is sleeved on the first movable base 710, and the first gear ring 730 and the first movable base 710 are threaded together. A second movable base 720 is sleeved on the second gear ring 740, and the second movable base 720 and the second gear ring 740 are threaded together. The inner diameter of the second gear ring 740 is larger than the outer diameter of the first gear ring 730, and the second gear ring 740 is spaced apart from the first gear ring 730. The drive wheel 760 is connected to the motor 750, either by mounting the drive wheel 760 on the drive shaft of the motor 750 or by a transmission connection between the drive wheel 760 and the drive shaft of the motor 750 via a gear set. The drive wheel 760 is meshed between the first gear ring 730 and the second gear ring 740, meaning that the drive wheel 760 simultaneously meshes with both the first gear ring 730 and the second gear ring 740.When the motor 750 drives the drive wheel 760 to rotate, the drive wheel 760 drives the first gear ring 730 and the second gear ring 740 to rotate in opposite directions, thereby driving the first movable seat 710 and the second movable seat 720 to move relative to each other in the same direction. Alternatively, when the motor 750 drives the drive wheel 760 to rotate clockwise, the drive wheel 760 drives the first gear ring 730 to rotate clockwise. The first gear ring 730, through its threaded connection with the first movable seat 710, drives the first movable seat 710 to move to the right, thereby driving the mirror body 400 and the first mounting seat 300 to move to the right. Simultaneously, the drive wheel 760 drives the second gear ring 740 to rotate counterclockwise. The second gear ring 740, through its threaded connection with the second movable seat 720, drives the second movable seat 720 to move to the right, thereby driving the second mounting seat 500 to move to the right. When the motor 750 drives the drive wheel 760 to reverse, the drive wheel 760 drives the first gear ring 730 to rotate counterclockwise. The first gear ring 730 drives the first movable seat 710 to move to the left through the threaded connection with the first movable seat 710, thereby driving the mirror body 400 and the first mounting seat 300 to move to the left. At the same time, the drive wheel 760 drives the second gear ring 740 to rotate clockwise. The second gear ring 740 drives the second movable seat 720 to move to the left through the threaded connection with the second movable seat 720, thereby driving the second mounting seat 500 to move to the left.

[0052] Based on the above embodiments, specifically, the first movable seat 710 is provided with a first external thread 711, the inner side of the first gear ring 730 is provided with a first internal thread 731 that connects to the first external thread 711, and the outer side of the first gear ring 730 is provided with a first tooth surface 732. The inner side of the second gear ring 740 is provided with a second tooth surface 741, the outer side of the second gear ring 740 is provided with a second external thread 742, and the inner side of the second movable seat 720 is provided with a second internal thread 721 that connects to the second external thread 742. The outer side of the drive wheel 760 is provided with a third tooth surface 761, and the drive wheel 760 is located between the first gear ring 730 and the second gear ring 740 and meshes with the first tooth surface 732 and the second tooth surface 741.
