Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to a dust cleaning mechanism of a release brush and a negative ion generating device. Background Art

[0002] The negative ion generating device includes a negative ion generator and a negative ion releaser. The negative ion releaser includes a release brush made of metal or carbon. When the working time accumulates to a certain extent, the release brush is prone to accumulate dust, which reduces the negative ion release efficiency and affects the air quality. To deal with this situation, the technicians specially set up a cleaning mechanism at the corresponding position of the release brush to clean the dust on the release brush.

[0003] The cleaning mechanism generally includes a cleaning drive device and a cleaning member connected by a transmission. In the prior art, the cleaning drive device generally adopts a motor, which drives the cleaning member to move linearly to sweep the release brush, thereby cleaning the dust on the release brush. However, the application scenarios of the negative ion generating device include shower places or other scenarios that are easily exposed to liquids. Since the motor needs to drive the movement of the cleaning member by rotating the motor shaft, the liquid can easily enter the inside of the motor through the gap between the motor shaft and the motor housing. After the motor is flooded, it is very easy to be damaged, making the cleaning mechanism unable to work. Therefore, it is difficult to improve the waterproof level by using a motor as a cleaning drive device, and the cleaning mechanism of the negative ion releaser is easily damaged when it comes into contact with water.

[0004] Later, a cleaning mechanism appeared that used an electromagnet as a cleaning drive device. However, the cleaning mechanism did not waterproof the coil of the electromagnet. As long as part of the wire of the coil was exposed, it would easily cause accidents such as coil short circuit, making the cleaning mechanism of the negative ion releaser easily damaged.

[0033] like Figures 1 to 10As shown, a dust cleaning mechanism with a release brush includes a cleaning electromagnet 1, an electromagnet mounting frame 2 and a cleaning member 3; the electromagnet mounting frame 2 includes a winding post 21, the interior of the winding post 21 is provided with an iron core through hole 211 extending along its length direction, the coil 12 of the cleaning electromagnet 1 is wound on the winding post 21, the iron core 11 of the cleaning electromagnet 1 is passed through the iron core through hole 211, one end of the iron core 11 is a cleaning end 112, the cleaning end 112 protrudes from the iron core through hole 211 and is provided with a cleaning member 3; a coil waterproof structure 4 is provided on the peripheral side of the winding post 21, and the coil 12 is sealed between the coil waterproof structure 4 and the outer surface of the winding post 21.

[0034] The coil waterproof structure 4 is provided to seal the coil 12 between the coil waterproof structure 4 and the outer surface of the winding post 21, so that the coil 12 is difficult to contact with liquid, but as long as the power is turned on, the iron core 11 can still be driven to move without affecting its function. The dust cleaning mechanism in the utility model has a strong waterproof performance and is not easily damaged even in an environment that is easily exposed to liquid, which is conducive to extending its service life and expanding its scope of application.

[0035] In some specific embodiments, the coil waterproof structure 4 includes waterproof glue, and the waterproof glue wraps the coil 12 .

[0036] In some specific embodiments, reference Figure 1 and Figure 4 A cavity 22 is provided in the electromagnet mounting frame 2 , and the winding post 21 is provided in the cavity 22 ; the waterproof glue is a potting glue 41 , and the potting glue 41 is poured into the cavity 22 and covers the coil 12 .

[0037] Specifically, the overall profile of the electromagnet mounting frame 2 is in the shape of a rectangular box, and openings 24 are provided on the two opposite side walls of the electromagnet mounting frame 2, and the two openings 24 are both connected to the cavity 22. Two arc surfaces 23 are provided on the inner wall of the cavity 22, and the two arc surfaces 23 are arranged opposite to each other, and the two edges of the arc surface 23 are respectively connected to the two side walls provided with the openings 24, and the edges of the arc surface 23 are connected to the edges of the openings 24. The axis of the arc surface 23 is in the same straight line as the axis of the winding post 21, and the winding post 21 is arranged between the two arc surfaces 23. The arc surface 23 is provided to facilitate winding the wire into the coil 12 on the winding post 21 in the electromagnet mounting frame 2.

[0038] During potting, one of the openings 24 may be facing upwards, the other opening 24 may be blocked, and then the potting glue 41 may be poured into the cavity 22 until the potting glue 41 covers the coil 12. Finally, the potting glue 41 may be heated or left to stand at room temperature to solidify the potting glue 41, thereby sealing the coil 12 to achieve the purpose of waterproofing.

[0039] Furthermore, during the pouring, the cavity 22 is filled up to maximize the waterproof performance.

[0040] In some other embodiments, the waterproof glue can also use PS glue, PA glue, etc., and form a sealed waterproof layer on the outside of the coil 12 through coating or the like, that is, the coil waterproof structure 4, and seal the coil 12 between the coil waterproof structure 4 and the outer surface of the winding column 21 to achieve the purpose of waterproofing.

[0041] In some specific embodiments, the potting glue 41 is epoxy resin potting glue 41 .

[0042] The epoxy resin potting glue 41 has good adhesion, can be well combined with the inner wall of the cavity 22, and is not easy to fall off, which is beneficial to improving the structural stability of the dust cleaning mechanism; in addition, the epoxy resin potting glue 41 also has good insulation performance, which can further reduce the possibility of short circuit of the coil 12, which is beneficial to further extend the service life of the dust cleaning mechanism.

[0043] In some specific embodiments, the coil 12 is formed by winding a conductive wire, and the conductive wire is an enameled wire.

[0044] The enameled wire includes a conductor and an insulating layer and has a certain insulating capacity. Using the enameled wire as the conductor is beneficial to further reduce the possibility of short circuit of the coil 12 and the probability of damage to the dust cleaning mechanism.

[0045] In addition, since the electromagnet needs to be energized, in addition to being wound into the coil 12, a section of the wire needs to extend to the outside of the electromagnet mounting frame 2 to connect to the power supply. This section of the wire is an enameled wire, which is also conducive to ensuring the energization stability of the electromagnet.

[0046] In some specific embodiments, the coil waterproof structure 4 is a waterproof tape, which is wound around the outside of the coil 12 to seal the coil 12 between the waterproof tape and the outer surface of the winding pole 21 .

[0047] In some specific embodiments, reference Figure 4 and Figure 6 The other end of the iron core 11 is an elastic reset end 111, which protrudes from the iron core through hole 211 and is provided with a flange 1111. A reset spring 113 is sleeved on the iron core 11, and the reset spring 113 is arranged between the flange 1111 and the electromagnet mounting frame 2.

[0048] A reset spring 113 is sleeved on the iron core 11, which can drive the iron core 11 and the cleaning member 3 to reset after the cleaning member 3 cleans the release brush 302. After the cleaning electromagnet 1 is energized, the iron core 11 moves along its axial direction, driving the cleaning member 3 to clean the release brush 302. During this process, the flange 1111 gradually approaches the electromagnet mounting frame 2, and the flange 1111 and the electromagnet mounting frame 2 compress the reset spring 113. After cleaning, the reset spring 113 applies a reset elastic force to the flange 1111, so that the flange 1111 moves away from the electromagnet mounting frame 2, and at the same time drives the iron core 11 and the cleaning member 3 to reset, so as to facilitate the next movement of the iron core 11 and the cleaning member 3. The reset spring 113 can realize the automatic reset of the iron core 11, which is convenient to use, and the release brush 302 can be cleaned again during the reset process, which is conducive to improving cleaning efficiency and reducing power consumption.

[0049] In some other embodiments, the return spring 113 is not provided on the iron core 11 , and the reciprocating motion of the iron core 11 can be achieved by changing the direction of the current in the coil 12 .

[0050] In some specific embodiments, reference Figure 1 and Figure 2 The cleaning member 3 is rod-shaped, and the extending direction of the cleaning member 3 is perpendicular to the extending direction of the iron core 11 .

[0051] After the cleaning electromagnet 1 is energized and drives the iron core 11 to move, the cleaning member 3 will move synchronously and sweep across the release brush 302 , causing the release brush 302 to deform and bounce off the dust on the release brush 302 , thereby playing the role of cleaning the release brush 302 .

[0052] This embodiment also provides a negative ion air purification device, referring to Figures 5 to 10 , including the dust cleaning mechanism of the above-mentioned release brush 302.

[0053] In some specific embodiments, the release brush 302 is made of carbon. The release brush 302 made of carbon is soft in texture, and the cleaning effect of the rod-shaped cleaning member 3 is better, which is more conducive to preventing dust accumulation.

[0054] In some specific embodiments, reference Figure 6 and Figure 7, also includes a shell 10 and a negative ion generator 20, a negative ion releaser 30 and a dust cleaning mechanism arranged on the shell 10, the negative ion releaser 30 includes a release brush 302; the cleaning electromagnet 1 and the release brush 302 are respectively arranged on both sides of the shell 10, and the shell 10 is also provided with a first avoidance hole 3011 for avoiding the cleaning end 112, so as to install the cleaning electromagnet 1 and allow the cleaning end 112 to pass through the first avoidance hole 3011, and the cleaning member 3 on the cleaning end 112 is located on the side of the shell 10 close to the release brush 302, and corresponds to the position of the release brush 302; a waterproof gasket 5 is embedded between the electromagnet mounting frame 2 and the shell 10, the waterproof gasket 5 is used to block the first avoidance hole 3011, and a second avoidance hole 51 is provided on the waterproof gasket 5 for the cleaning end 112 to pass through, and the second avoidance hole 51 is smaller than the first avoidance hole 3011.

[0055] In some specific embodiments, reference Figure 8 and Fig. 9 The negative ion air purification device also includes a generator housing 201 and a releaser housing 301. The negative ion generator 20 and the negative ion releaser 30 are respectively arranged in the generator housing 201 and the releaser housing 301.

[0056] Specifically, the housing 10 includes a bottom plate 102 and a cover plate 101, and the negative ion generator 20, the negative ion releaser 30 and the dust cleaning mechanism are arranged on the bottom plate 102. The bottom plate 102 is arched upward to form a releaser housing 301, and the bottom of the releaser housing 301 has a receiving cavity 3012, and the release brush 302 and the cleaning member 3 are arranged in the receiving cavity 3012.

The first avoidance hole 3011 extends from the upper part of the releaser housing 301 to the side wall of the releaser housing 301 near the electromagnet mounting position 1021, so that when the electromagnet mounting frame is installed on the electromagnet mounting position 1021 from top to bottom, the first avoidance hole 3011 can provide space for the cleaning end 112 of the iron core 11, so that the electromagnet mounting frame 2 can be installed smoothly.

[0057] refer to Figure 7The waterproof gasket 5 is made of silica gel. In this embodiment, the waterproof gasket 5 is L-shaped, so that the waterproof gasket 5 can block the first avoidance hole 3011 from the upper side and side wall of the releaser housing 301. The portion of the waterproof gasket 5 corresponding to the side wall of the releaser housing 301 is embedded between the electromagnet mounting frame 2 and the releaser housing 301, so that the waterproof gasket 5 is firmly positioned. The second avoidance hole 51 on the waterproof gasket 5 is used to avoid the iron core 11, so that the iron core 11 can smoothly drive the cleaning member 3 to move.

[0058] The negative ion generator 20 and the negative ion releaser 30 together constitute a negative ion generating device. In this embodiment, the generator housing 201 and the releaser housing 301 are separately provided to reduce the overall thickness of the negative ion generating device, so that it can be used in equipment with a smaller thickness, thereby expanding the application range of the negative ion generating device.

[0060] refer to Figure 5 and Figure 7 The housing 10 is provided with a wire through hole, through which the wires in the housing 10 pass out of the housing 10 and are connected to the power supply device. A wire protection waterproof ring 6 is provided in the wire through hole to prevent liquid from entering the housing 10, further improving the waterproof performance.
