Description

Technical Field

[0001] The invention relates to the technical field of air conditioner negative ion generating equipment, in particular to a friction plate and a water negative ion generator thereof. Background Art

[0002] Negative ions have air purification effects such as dust removal and sterilization. Existing negative ion generating machines are generally formed by high-voltage ionized air. In order to obtain a higher concentration of negative ions, Chinese patent CN116053936A discloses a water negative ion generating device and a water negative ion injection structure thereof. The water negative ion generating device includes a water storage container and a water negative ion injection structure. The water negative ion injection structure includes a bracket, a friction buffer device, a water negative ion injection device, an insulating layer and a conductive layer. The bracket has an accommodating channel. The friction buffer device is arranged in the accommodating channel and has water absorption and elasticity. The water negative ion injection device is used to vibrate the water in the friction buffer device.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Firstly, the rotary drum in the present invention is rotatably installed in the mounting hole and passes through the partition to fit with the friction plate body. A cleaning scraper is provided at one end of the rotary drum that fits with the friction plate body. When the friction plate body vibrates in the mounting hole, the rotary drum follows the vibration. The driving unit connected to the cleaning unit can make the rotary drum rotate around its own axis when the friction plate body vibrates, so that the cleaning scraper fits the surface of the friction plate body and moves. The cleaning scraper can promptly remove impurities attached to the surface of the friction plate body, thereby avoiding the situation where impurities block the micropores and ensuring the long-term operation of the water negative ion generator.

[0017] Secondly, the bevel gear on the circumferential side of the contact ring in the present invention is meshed with the bevel gear ring on the outer wall of the rotating drum. When the contact ring moves in the axial direction of the mounting hole, the synchronous gear coaxially connected to the bevel gear moves on the mounting plate, and the ratchet on the mounting plate is meshed with the synchronous gear. Therefore, when the contact ring reciprocates in the axial direction of the mounting hole, the synchronous gear rotates unidirectionally under the action of the ratchet of the mounting plate, thereby driving the bevel gear ring, the rotating drum and the cleaning scraper to rotate unidirectionally, thereby realizing the movement of the cleaning scraper to clean impurities on the surface of the friction plate main body.

[0018] Thirdly, the contact ring in the present invention is inserted into the guide sleeve arranged on the shell through the guide rod to fix the moving path of the contact ring. When the friction plate body vibrates, the contact ring can only move in the axial direction of the mounting hole, which neither affects the normal vibration of the friction plate body nor ensures the stability of the relative movement state of the synchronous gear and the mounting plate.

DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Reference Figures 1 to 13 :

[0035] A friction plate comprises a circular friction plate body 1, a plurality of micropores 11 arranged at the center of the friction plate body 1, and an annular piezoelectric ceramic plate 12 fitted with the friction plate body 1, the axis of the annular piezoelectric ceramic plate 12 is on the same straight line as the axis of the friction plate body 1, and an insulating sleeve 13 sleeved on the outside of the friction plate body 1 and the annular piezoelectric ceramic plate 12, the insulating sleeve 13 is elastic; the friction plate body 1 and the annular piezoelectric ceramic plate 12 are both connected with wiring terminals 14, and the wiring terminals 14 pass through the insulating sleeve 13 and extend to the outside of the insulating sleeve 13.

[0036] The friction plate body 1 in the present application is made of conductive material, the annular piezoelectric ceramic sheet 12 is fitted to the friction plate body 1, and the insulating sleeve 13 wraps the friction plate body 1 and the annular piezoelectric ceramic sheet 12 therein. After the terminal 14 is energized, when a voltage of a predetermined frequency and peak value is applied to the friction plate body 1, the friction plate body 1 will generate high-frequency vibrations and hit the water droplets passing through the micropores 11 in the center of the friction plate body 1, thereby causing the water to resonate and produce tiny water droplets, and the tiny water droplets rub against the friction plate body 1 at a high frequency while being generated, so that the tiny water droplets are further negatively charged to form charged water droplets and diffuse from the micropores 11 into the environment. The insulating sleeve 13 has a certain elastic force to ensure that the friction plate body 1 can vibrate at a high frequency.

[0037] In order to solve the problem of impurities being left attached to the surface of the friction plate body 1 when water molecules pass through the micropores 11, the following features are specifically set:

[0038] A water negative ion generator includes a friction plate, a housing 2 for mounting a friction plate body 1, and an ionization device 3 mounted on the housing 2, the housing 2 includes a water inlet channel 21, and a mounting block 22 arranged at the bottom of the water inlet channel 21, the mounting block 22 is provided with a plurality of mounting holes 221 for mounting the friction plate body 1, and a partition 222 (such as Figure 6 As shown, the friction plate body 1 is arranged at one end of the partition 222 away from the water inlet channel 21; a cleaning unit 23 is arranged in the mounting hole 221, and the cleaning unit 23 includes a rotating drum 231 and a cleaning scraping wire 232. The rotating drum 231 is located at one end of the partition 222 close to the water inlet channel 21, and the cleaning scraping wire 232 is installed in the rotating drum 231 and extends radially along the rotating drum 231 (as shown in FIG. Figure 7 As shown in the figure, the diameter of the cleaning scraper 232 is smaller than the diameter of the micropore 11, and one end of the cleaning scraper 232 installed on the rotating drum 231 passes through the partition 222 to fit the friction plate body 1, and the cleaning scraper 232 fits the surface of the friction plate body 1; a driving unit 24 is provided in the housing 2, which is used to drive the rotating drum 231 and the cleaning scraper 232 to rotate around the axis when the friction plate body 1 vibrates.

[0039] The water negative ion generator in the present application is installed on the air conditioner, and the water inlet channel 21 of the shell 2 allows water to flow into the mounting hole 221 of the bottom mounting block 22. After the water passes through the friction plate body 1 installed in the mounting hole 221, water negative ions are generated and sprayed to the outside. A partition 222 is arranged in the mounting hole 221 in this embodiment, and the friction plate body 1 is located on one side of the partition 222. A cleaning unit 23 for cleaning the friction plate body 1 toward the side of the partition 222 is arranged on the other side of the partition 222. The rotating drum 231 is rotatably installed in the mounting hole 221 and passes through the partition 222 to fit with the friction plate body 1. When the friction plate body 1 vibrates, the rotating drum 231 vibrates with the friction plate body 1. A cleaning scraping line 232 is arranged at one end of the rotating drum 231 that fits with the friction plate body 1. Since the cleaning scraping line 232 It extends radially along the rotating drum 231, so the cleaning scraper line 232 also passes through the axis of the friction plate body 1, and because the diameter of the cleaning scraper line 232 is smaller than the diameter of the micropores 11, the cleaning scraper line 232 will not completely block part of the micropores 11, and will not affect the water molecules passing through the micropores 11 of the friction plate body 1 to produce tiny water droplets. When the friction plate body 1 vibrates in the mounting hole 221, the rotating drum 231 follows the vibration, and the driving unit 24 connected to the cleaning unit 23 can make the rotating drum 231 rotate around its own axis when the friction plate body 1 vibrates, so that the cleaning scraper line 232 moves in contact with the surface of the friction plate body 1, and the cleaning scraper line 232 can promptly remove impurities attached to the surface of the friction plate body 1, thereby avoiding the situation where impurities block the micropores 11, and ensuring the long-term operation of the water negative ion generator.

[0040] In order to solve the problem of how the driving unit 24 drives the drum 231 to rotate when the friction plate body 1 vibrates, the following features are specifically provided:

[0041] The driving unit 24 includes a plurality of contact rings 241 elastically mounted in the housing 2. The contact ring 241 is coaxially arranged with the mounting hole 221. The contact ring 241 moves along the axis of the mounting hole 221 to push the end of the rotating cylinder 231 provided with the cleaning scraper 232 to fit the friction plate body 1. A bevel gear ring 233 is coaxially mounted on the outer wall of the rotating cylinder 231. A plurality of side mounting frames 242 (such as Fig.13 As shown, the bevel gear 243 rotatably mounted on the side mounting frame 242 is meshed with the bevel gear ring 233, the axis of the bevel gear 243 is perpendicular to the axis of the mounting hole 221, and the end of the bevel gear 243 away from the bevel gear ring 233 is coaxially connected to the synchronous gear 244 (as shown Figure 6 As shown); a plurality of mounting plates 25 are fixedly installed in the housing 2, and the mounting plates 25 extend into the mounting hole 221 along the axial direction of the mounting hole 221. The mounting plates 25 are provided with a plurality of ratchet teeth 251 arranged at equal intervals along the axial direction of the mounting hole 221, and the ratchet teeth 251 are meshed and connected with the synchronous gear 244.

[0042] The driving unit 24 in this embodiment includes a contact ring 241 elastically mounted on the housing 2. The contact ring 241 pushes the rotating drum 231 to fit the friction plate body 1. When the friction plate body 1 vibrates, the contact ring 241 and the rotating drum 231 synchronously follow the vibration of the friction plate body 1. The contact ring 241 can only move in the axial direction of the mounting hole 221 when the friction plate body 1 vibrates. The bevel gear 243 on the circumference of the contact ring 241 is meshed and connected with the bevel gear ring 233 on the outer wall of the rotating drum 231. When the contact ring 241 moves in the axial direction of the mounting hole 221, the synchronous gear 244 coaxially connected to the bevel gear 243 moves on the mounting plate 25, and the ratchet 251 on the mounting plate 25 It is meshed with the synchronous gear 244, so when the contact ring 241 reciprocates in the axial direction of the mounting hole 221, the synchronous gear 244 rotates unidirectionally under the action of the ratchet 251 of the mounting plate 25, thereby driving the bevel gear ring 233, the rotating drum 231 and the cleaning scraper 232 to rotate unidirectionally, so that the cleaning scraper 232 moves to clean the impurities on the surface of the friction plate body 1. In this embodiment, the contact ring 241 fits the rotating drum 231 under the action of elastic force, and the rotating drum 231 pushes the contact ring 241 back when the friction plate body 1 vibrates. Therefore, the relative positions of the rotating drum 231 and the contact ring 241 are fixed, ensuring that the meshed connection state between the bevel gear ring 233 and the bevel gear 243 is stable.

[0043] In order to ensure that the contact ring 241 can only move in the horizontal direction, the following features are specifically set:

[0044] A plurality of guide rods 245 are provided at one end of the contact ring 241 away from the cleaning unit 23. The axis of the guide rod 245 is parallel to the axis of the mounting hole 221. The guide rod 245 is inserted into a guide sleeve 26 provided in the housing 2. The outer sleeve of the guide sleeve 26 is provided with a spring 261 (such as Figure 6 As shown in the figure), the spring 261 elastically connects the housing 2 and the contact ring 241, and the elastic force of the spring 261 causes the contact ring 241 to move toward the rotating drum 231.

[0045] The contact ring 241 in this embodiment is provided with a guide rod 245. A plurality of guide rods 245 are inserted into a guide sleeve 26 provided on the housing 2 to fix the moving path of the contact ring 241. When the friction plate body 1 vibrates, it pushes the rotating cylinder 231. When the rotating cylinder 231 pushes the contact ring 241, the contact ring 241 can only move in the axial direction of the mounting hole 221 to ensure the relative movement of the synchronous gear 244 and the mounting plate 25. The spring 261 provided on the guide sleeve 26 elastically connects the housing 2 and the contact ring 241. The elastic force of the spring 261 ensures the fit between the contact ring 241 and the rotating cylinder 231.

[0046] In order to solve the problem of how to install the ratchet 251 on the mounting plate 25 to ensure the unidirectional rotation of the driving synchronous gear 244, the following features are specifically set:

[0047] The ratchet 251 is rotatably mounted on the side of the mounting plate 25 facing the synchronous gear 244 (eg Fig.10 As shown in the figure, the axis of the ratchet 251 is perpendicular to the axis of the synchronous gear 244, and a limit block 252 is provided at one end of each ratchet 251 away from the synchronous gear 244. The mounting plate 25 is provided with a top block 253 located on one side of each limit block 252, and an elastic sheet 254 is provided on the side of each limit block 252 away from the top block 253. The elastic force of the elastic sheet 254 makes the limit block 252 fit the top block 253.

[0048] The ratchet 251 in this embodiment is rotatably mounted on the mounting plate 25, and the limit block 252 of the ratchet 251 is in contact with the top block 253 of the mounting plate 25 under the elastic force of the elastic sheet 254. Therefore, when the synchronous gear 244 translates toward the elastic sheet 254, the limit block 252 is restricted by the top block 253, resulting in that the ratchet 251 cannot rotate. Therefore, the synchronous gear 244 rotates to drive the rotating drum 231 of the cleaning unit 23 to rotate. When the synchronous gear 244 translates toward the top block 253, the synchronous gear 251 The teeth of 244 push the ratchet 251, and the limit block 252 of the ratchet 251 compresses the elastic sheet 254 to move away from the top block 253, allowing the synchronous gear 244 to pass. After the synchronous gear 244 passes through the ratchet 251, the elastic force of the elastic sheet 254 causes the ratchet 251 to reset to the limit block 252 to fit the top block 253, and the synchronous gear 244 will not rotate, thereby ensuring that the rotating drum 231 of the cleaning unit 23 can only rotate in one direction to drive the cleaning scraper 232 to clean the surface of the friction plate body 1.

[0049] In order to ensure that the water in the water inlet channel 21 can enter the mounting block 22 and can only be discharged through the micropores 11 of the friction plate body 1, the following features are specifically provided:

[0050] The contact ring 241 is attached to the inner wall of the drum 231, and a sealing rubber ring 247 (such as Figure 8 As shown in the figure), when the sealing rubber ring 247 is attached to the rotating drum 231, the connection between the contact ring 241 and the rotating drum 231 is sealed.

[0051] A plurality of balls 248 (such as Figure 6 As shown in FIG. 1 ), the ball 248 protrudes from the outer wall of the contact ring 241 and contacts the inner wall of the drum 231.

[0052] The contact ring 241 in this embodiment is inserted into the rotating drum 231 to realize the coaxial connection between the contact ring 241 and the rotating drum 231. The sealing rubber ring 247 on the top of the contact ring 241 fits the rotating drum 231 to prevent water that passes through the contact ring 241 from entering the connection between the rotating drum 231 and the contact ring 241. The ball 248 on the side of the contact ring 241 contacts the inner wall of the rotating drum 231. The ball 248 reduces the resistance encountered by the rotating drum 231 when it rotates, making it convenient for the rotating drum 231 to rotate and drive the cleaning scraper 232 to rotate.

[0053] In order to ensure that the cleaning scraping line 232 fits the surface of the friction plate body 1, the following features are specifically set:

[0054] The cleaning scraper line 232 is provided with mounting sliders 234 (such as Fig.12As shown in the figure, the mounting slide blocks 234 are respectively slidably mounted in two mounting grooves 235 provided on the inner wall of the rotating drum 231, and the mounting grooves 235 extend along the axial direction of the rotating drum 231 and are symmetrical about the center of the axial line of the rotating drum 231; the side walls of the mounting grooves 235 are provided with threaded holes, and locking bolts 236 are spirally installed in the threaded holes, and the locking bolts 236 are fitted against the side walls of the mounting slide blocks 234 to lock the position of the mounting slide blocks 234 in the mounting grooves 235.

[0055] The cleaning scraper line 232 in this embodiment can be a line or a scraper blade, etc. The mounting sliders 234 at both ends of the cleaning scraper line 232 are slidably installed in the mounting groove 235 on the inner wall of the rotating drum 231. The staff manually adjusts the position of the mounting slider 234 in the mounting groove 235 to align the cleaning scraper line 232 with the top of the rotating drum 231, thereby ensuring that the cleaning scraper line 232 is in contact with the surface of the friction plate body 1 when the rotating drum 231 is in contact with the friction plate body 1. After the mounting slider 234 moves in the mounting groove 235, the staff can rotate the locking bolt 236 installed on the side wall of the mounting groove 235. After the locking bolt 236 is tightened, the position of the mounting slider 234 in the mounting groove 235 is ensured to be stable.

[0056] In order to solve the problem of how to ensure that the friction plate body 1 only vibrates in the mounting hole 221, the following features are specifically set:

[0057] A limiting plate 223 is coaxially mounted on one end of the mounting hole 221 of the mounting block 22 away from the cleaning unit 23. The inner diameter of the limiting plate 223 is smaller than the diameter of the friction plate body 1 (eg, Fig.11 as shown).

[0058] The friction plate body 1 in this embodiment is installed in the mounting hole 221, and the contact ring 241 elastically installed in the shell 2 pushes the rotating cylinder 231 to contact the friction plate body 1. The friction plate body 1 fits the limit plate 223 at one end of the mounting hole 221 under the thrust of the rotating cylinder 231. Since the inner diameter of the limit plate 223 is smaller than the diameter of the friction plate body 1, the friction plate body 1 can only vibrate between the limit plate 223 and the partition plate 222 and will not separate from the mounting hole 221, and the tiny water droplets generated through the micropores 11 can be sprayed out through the limit plate 223.

[0059] In order to solve the problem of how to make tiny water droplets carry negative ions, the following features are specifically set:

[0060] The ionization device 3 includes an ionization needle 31 and a mounting bracket 32 ​​for mounting the ionization needle 31. The mounting bracket 32 ​​is fixedly mounted in an axial hole 224 provided at the axis of the mounting block 22 (eg, Figure 5 and Fig.11 As shown); the ionization device 3 also includes a power supply 33 for supplying power to the ionization needle 31.

[0061] The ionization needle 31 in this embodiment is installed in the axial hole 224 at the axis of the mounting block 22. The mounting hole 221 can be arranged around the axial hole 224 so that the ionization needle 31 is located near the friction plate body 1, and generates negative ions such as negative oxygen ions by ionizing the air. These negative ions replenish the charge of the tiny water droplets generated by the micropores 11 passing through the friction plate body 1, so that the water negative ions generated by the friction plate body 1 tend to be saturated with charge, so that the present application can generate high concentrations of water negative ions.

[0062] Working principle: The water inlet channel 21 of the housing 2 allows water to flow into the mounting hole 221 of the bottom mounting block 22. After the water passes through the friction plate body 1 installed in the mounting hole 221, water negative ions are generated and sprayed to the outside. After the wiring terminal 14 is energized, when a voltage with a predetermined frequency and peak value is applied to the friction plate body 1, the friction plate body 1 will generate high-frequency vibrations and hit the water droplets passing through the micropores 11 in the center of the friction plate body 1, so that the water resonates to generate tiny water droplets, and the tiny water droplets rub against the friction plate body 1 at a high frequency while being generated, so that the tiny water droplets are further negatively charged to form charged water droplets. And it diffuses into the environment from the micropores 11. When the friction plate main body 1 vibrates in the mounting hole 221, the rotating drum 231 follows the vibration. The rotating drum 231 is rotatably installed in the mounting hole 221 and passes through the partition 222 to fit with the friction plate main body 1.
