Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, specifically to an oxygen-containing negative ion air-purifying humidifier. Background Technology

[0002] In the field of humidifier technology, humidifiers, as a common environmental control device, are mainly used to increase air humidity to improve dry indoor environments and enhance human comfort. Traditional humidifiers typically increase air humidity by atomizing water molecules, but these devices often have a single function, focusing only on humidity regulation while neglecting other key factors of air quality, such as air freshness and negative ion concentration. With the increasing severity of environmental pollution, user demand for humidifiers has expanded from simple humidity control to integrated designs that combine air purification, negative ion release, and other functions to create a healthier living environment.

[0003] For example, Chinese Patent Publication No. CN204693717U discloses "A superoxide negative ion humidifier, comprising a body composed of a front panel and a rear shell, with a filtration and purification inner cavity inside the body. The surface of the front panel is covered with air outlets, and the back of the rear shell is covered with air inlets. Its structural feature is that a negative ion generator is provided on the inner bottom surface of the front panel, and a filter screen and a filter fan are provided on the inner bottom surface of the rear shell corresponding to the distribution positions of the air inlets; a humidification device is provided at the top of the rear shell; and several negative ion diffusion frames are evenly distributed on the inner bottom surface of the front panel corresponding to the distribution positions of the air outlets. A negative ion diffusion conduit connected to the negative ion generator is continuously wound around the diffusion frame in an S-shape. The filter screen is tightly attached to or clamped to..." The rear shell has an inner bottom that completely covers the distribution of the air inlet holes; the filter fan is installed at the geometric center of the distribution of the air outlet holes. A recessed platform is provided at the top of the rear shell, and the humidifying device is installed on this platform. The humidifying device includes a bottom shell, a front shell, an atomizer, and a humidifying fan. The bottom shell is embedded in the rear shell, and its interior has a water storage tank and an air outlet channel separated from each other. The atomizer is connected to the bottom of the water storage tank, and the air outlet end of the humidifying fan is connected to the air outlet channel. The front shell covers the bottom shell, with a water inlet at one end connected to the water storage tank and a mist outlet at the other end. An internal partition separates the water inlet and the mist outlet, and the partition connects the air outlet channel to the mist outlet channel but separates it from the water inlet channel.

[0004] However, in existing technologies, this type of humidifier uses a simple atomization structure and a unidirectional airflow design, which leads to several significant problems: First, traditional humidifiers lack a negative ion generation mechanism, making them unable to effectively neutralize harmful substances in the air (such as dust, bacteria, or volatile organic compounds), thus failing to substantially improve air quality after humidification. While negative ions are widely recognized for their air-purifying and immune-boosting properties, their integration into humidifiers is relatively low. Secondly, the water mist distribution in existing equipment often relies on fixed air guides or natural diffusion, resulting in uneven distribution of water mist within the humidification chamber, easily creating localized areas of excessive humidity or dryness. For example, water mist may concentrate near the air intake pipe, while areas further away may lack sufficient humidity, affecting the overall humidification effect. In addition, slow airflow and low intake and exhaust efficiency prolong the humidification cycle, failing to meet the requirements for efficient humidification. Utility Model Content

[0005] This invention proposes an oxygen-containing negative ion air freshener and humidifier, which solves the problem of poor air humidification and purification effects in related technologies.

[0007] Preferably, a filter screen is fixedly connected to the inlet end of the air intake pipe, and a water injection pipe is connected to one side of the water tank.

[0008] Preferably, the negative pressure mechanism includes a mounting bracket fixedly connected to the inside of the air outlet pipe, and an air suction impeller is rotatably connected to the inside of the mounting bracket.

[0009] Preferably, the negative pressure mechanism further includes a mounting box fixedly connected to the bottom of the mounting frame. A first bevel gear, coaxially fixed with the suction impeller, is rotatably connected to the inner side of the mounting box. A rotating shaft penetrating the inner wall of the mounting box is rotatably connected to one end of the mounting box. A second bevel gear is fixedly connected to one end of the rotating shaft. The second bevel gear is located inside the mounting box and meshes with the first bevel gear. A driving component for driving the rotating shaft to rotate is provided at the other end of the rotating shaft.

[0010] Preferably, the tooth ratio of the first bevel gear to the second bevel gear is 1:8.

[0011] Preferably, the driving component includes a drive motor fixedly installed on the outside of the humidification box, the output shaft of the drive motor is fixedly connected to a first pulley, and the end of the rotating shaft is fixedly connected to a second pulley, the second pulley and the first pulley being connected by a belt drive.

[0012] Preferably, the linkage mechanism includes several rotating plates coaxially and fixedly connected to the air guide plate. The same end of the several rotating plates is movably connected to a linkage plate through a pin. The linkage plate is provided with several clearance grooves that slide with the pins of the corresponding rotating plates. The top of the linkage plate is provided with a transmission component that drives the linkage plate to reciprocate in the horizontal direction by cooperating with the start of the drive motor.

[0013] Preferably, the transmission component includes a movable frame fixedly connected to the top of the linkage plate, guide rails fixedly connected to both ends of the outer side of the humidification box, and the two ends of the movable frame slidably connected to the two guide rails respectively. Two racks symmetrically distributed along the center line of the movable frame are fixedly connected to the inner side of the movable frame. A bracket is fixedly connected to the outer wall of the humidification box, and a sector gear is rotatably connected to the bracket. The sector gear alternately meshes with the two racks.

[0014] Preferably, the transmission component further includes a first spur gear fixed coaxially with the sector gear, and a second spur gear is fixedly connected to the output shaft of the drive motor, the second spur gear meshing with the first spur gear.

[0015] The working principle and beneficial effects of this utility model are as follows: 1. Integrated negative ion generator continuously releases negative ions into the air inside the humidifier. Negative ions effectively neutralize harmful substances in the air (such as dust, bacteria, and volatile organic compounds), significantly improving air quality. Combined with the pre-filtration function of the filter, it reduces pollutants entering at the source, ensuring that the humidified air is not only at a suitable humidity level but also fresh and healthy.

[0016] 2. Through the coordinated action of the air guide plate and the linkage mechanism, the water mist achieves dynamic and uniform diffusion within the humidification chamber. The air guide plate can swing back and forth, directing the water mist sprayed by the atomizer to different areas of the humidification chamber, eliminating the "localized over-humidification" or "dry dead zones" commonly found in traditional equipment. This ensures consistent humidity throughout the space, improving user comfort.

[0017] 3. The negative pressure mechanism generates negative pressure in the outlet pipe through a high-speed suction impeller, accelerating the intake of outside air into the humidification chamber, where it mixes rapidly with the water mist. Compared to traditional unidirectional airflow designs, this solution increases airflow speed and significantly shortens the humidification cycle. Attached Figure Description

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] This application discloses an oxygen-containing negative ion air freshener and humidifier. Please refer to the embodiments provided. Figure 1 and Figure 3An oxygen-containing negative ion air freshening humidifier includes a housing 1. A humidification chamber 2 is fixedly connected to the inner side of the housing 1. An air inlet pipe 4 is fixedly connected to one end of the humidification chamber 2. A filter screen 5 is fixedly connected to the inlet end of the air inlet pipe 4. A water tank 6 is fixedly connected to the bottom wall of the inner side of the housing 1. A water pump 7 is fixedly installed on the top of the water tank 6. The inlet end of the water pump 7 is connected to the inside of the water tank 6 through a conduit. A water injection pipe 61 is connected to the outside of one side of the water tank 6. An atomizer 8 is fixedly connected to the outlet end of the water pump 7 through a conduit. The outlet end of the atomizer 8 is connected to the inside of the humidification chamber 2. When connected, a negative ion generator 13 is fixedly connected to the inner wall of the humidifier box 2, an air outlet pipe 3 is fixedly connected to the top of the humidifier box 2, a mist outlet pipe 14 is fixedly connected to the top of the shell 1, the mist outlet pipe 14 is connected to the air outlet pipe 3, a negative pressure mechanism 9 is provided on the inner side of the air outlet pipe 3, and several air guide plates 11 are rotatably connected to the bottom of the inner side of the humidifier box 2. The several air guide plates 11 are equidistantly distributed along the length direction of the humidifier box 2, and a linkage mechanism 12 is provided on the outer side of the humidifier box 2 to drive the several air guide plates 11 to swing back and forth by cooperating with the activation of the negative pressure mechanism 9.

[0023] By activating the negative pressure mechanism 9, the inlet end of the air outlet pipe 3 is placed under negative pressure, which in turn creates a negative pressure inside the humidifier box 2. This allows the air inlet pipe 4 to draw outside air into the humidifier box 2, while the filter screen 5 removes dust from the air, preventing dust from entering the humidifier box 2 and causing pollution. Then, the water pump 7, atomizer 8, and negative ion generator 13 are activated. The water pump 7 draws water from the water tank 6 and introduces it into the atomizer 8 for atomization. The water mist is then introduced into the humidifier box 2 through the outlet end of the atomizer 8 and mixed with the air. Meanwhile, the negative ion generator 13 generates negative ions that mix into the air. Finally, the water mist gas containing negative ions is discharged through the air outlet pipe 3 and the mist outlet pipe 14. This process achieves fresh humidification of the air and greatly improves air quality.

[0024] Please see Figures 1-4 The negative pressure mechanism 9 includes a mounting bracket 91 fixedly connected to the inside of the air outlet pipe 3. A suction impeller 92 is rotatably connected to the inside of the mounting bracket 91. A mounting box 93 is fixedly connected to the bottom wall of the mounting bracket 91. A first bevel gear 94, coaxially fixed with the suction impeller 92, is rotatably connected to the inside of the mounting box 93. A rotating shaft 95, penetrating the inner wall of the mounting box 93, is rotatably connected to one end of the mounting box 93. A second bevel gear 96 is fixedly connected to one end of the rotating shaft 95. The second bevel gear 96 is located inside the mounting box 93 and meshes with the first bevel gear 94. The tooth ratio of the first bevel gear 94 to the second bevel gear 96 is 1:8. A driving component 10 for driving the rotating shaft 95 to rotate is provided at the other end of the rotating shaft 95.

[0025] By activating the drive unit 10, the rotating shaft 95 is driven to rotate, causing the second bevel gear 96 to rotate synchronously. Since the first bevel gear 94 and the second bevel gear 96 mesh and their gear ratio is 1:8, the first bevel gear 94 rotates at high speed, which in turn causes the suction impeller 92 to rotate at high speed. This results in the inlet end of the air outlet pipe 3 being under negative pressure, which in turn causes the inside of the humidification box 2 to be under negative pressure. This allows the air inlet pipe 4 to quickly draw outside air into the humidification box 2 and mix it with water mist, thereby increasing the air flow speed and greatly improving the air humidification efficiency.

[0026] Please see Figure 1 and 5 The driving component 10 includes a drive motor 101 fixedly installed on the outside of the humidification box 2. The output shaft of the drive motor 101 is fixedly connected to a first pulley 102, and the end of the rotating shaft 95 is fixedly connected to a second pulley 103. The second pulley 103 and the first pulley 102 are connected by belt drive.

[0027] By starting the drive motor 101, the first pulley 102 is driven to rotate, and then the first pulley 102 drives the second pulley 103 to rotate synchronously. This causes the shaft 95 to rotate, and the second bevel gear 96 to rotate synchronously. Since the first bevel gear 94 and the second bevel gear 96 mesh and their gear ratio is 1:8, the first bevel gear 94 rotates at high speed, which in turn causes the suction impeller 92 to rotate at high speed. This results in the inlet end of the air outlet pipe 3 being under negative pressure, which in turn causes the inside of the humidification box 2 to be under negative pressure. This allows the air inlet pipe 4 to quickly draw outside air into the humidification box 2 and mix it with water mist, thereby increasing the air flow speed and greatly improving the air humidification efficiency.

[0028] Please see Figure 1 and 7The linkage mechanism 12 includes several rotating plates 121 coaxially fixedly connected to the air guide plate 11. A linkage plate 122 is movably connected to the same end of each rotating plate 121 via a pin. The linkage plate 122 has several clearance grooves 123 that slide with the pins of the corresponding rotating plates 121. A transmission component 124 is provided on the top of the linkage plate 122, which, when activated by the drive motor 101, drives the linkage plate 122 to reciprocate horizontally. The transmission component 124 includes a movable frame 1241 fixedly connected to the top of the linkage plate 122. Guide rails 1242 are fixedly connected to both ends of the outer side of the humidification box 2. The two ends of the frame 1241 are slidably connected to two guide rails 1242 respectively. Two racks 1243 symmetrically distributed along the center line of the movable frame 1241 are fixedly connected to the inner side of the movable frame 1241. A bracket 1244 is fixedly connected to the outer wall of the humidification box 2. A sector gear 1245 is rotatably connected to the bracket 1244. The sector gear 1245 alternately meshes with the two racks 1243. A first spur gear 1246 is fixedly fixed to the sector gear 1245 on the same axis. A second spur gear 1247 is fixedly connected to the output shaft of the drive motor 101. The second spur gear 1247 meshes with the first spur gear 1246.

[0029] Working principle: First, the drive motor 101, water pump 7, atomizer 8, and negative ion generator 13 are started. The drive motor 101 drives the first pulley 102 to rotate, and then the first pulley 102 drives the second pulley 103 to rotate synchronously. This causes the rotating shaft 95 to rotate, which in turn causes the second bevel gear 96 to rotate synchronously. Since the first bevel gear 94 meshes with the second bevel gear 96 and their gear ratio is 1:8, the first bevel gear 94 rotates at high speed, which in turn causes the suction impeller 92 to rotate at high speed. This causes the air intake of the outlet pipe 3 to... The inlet is under negative pressure, which makes the inside of the humidifier 2 also under negative pressure. This allows the air inlet pipe 4 to quickly draw outside air into the humidifier 2. The water pump 7 can draw water from the water tank 6 and introduce it into the atomizer 8 for atomization. Then, the water mist is introduced into the inside of the humidifier 2 through the outlet of the atomizer 8 to mix with the air. Meanwhile, the negative ion generator 13 generates negative ions that mix into the air. Finally, the water mist gas with negative ions is discharged through the air outlet pipe 3 and the mist outlet pipe 14. This can achieve fresh humidification of the air and greatly improve air quality. During the startup of the drive motor 101, the second spur gear 1247 is simultaneously driven to rotate. Since the second spur gear 1247 meshes with the first spur gear 1246, the first spur gear 1246 rotates synchronously, which causes the sector gear 1245 to rotate. Since the sector gear 1245 meshes alternately with the two racks 1243, the two sector gears 1245 drive the two racks 1243 to move alternately in opposite directions, thereby causing the movable frame 1241 to slide back and forth along the guide rail 1242, which in turn causes the linkage plate 122 to move back and forth in the horizontal direction, thereby causing all the rotating plates 121 to swing back and forth, which in turn causes all the air guide plates 11 to swing back and forth, so that the air guide plates 11 evenly guide the water mist sprayed by the atomizer 8 to different areas inside the humidification box 2, so that the air and water mist inside the humidification box 2 are quickly and evenly mixed, further improving the humidification effect.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
