Description

Technical Field

[0001] This invention relates to the field of air optimization technology, specifically to a high-concentration negative oxygen ion device for optimizing the air in hotel guest rooms and its usage method. Background Technology

[0002] One of the core competitive advantages of hotels is the guest experience, and air quality is a key factor affecting this experience. Upon check-in, guests may encounter unpleasant odors (such as lingering cigarette smoke from previous guests, renovation smells, or musty fabric odors) and dust particles in their rooms. Poor air quality can easily cause discomfort and even affect sleep quality and health. Air purification equipment (such as systems that generate negative oxygen ions) can effectively remove odors, absorb dust, and improve the freshness of the air in guest rooms.

[0003] However, with current technology, hotel rooms have a large flow of guests, and the air quality in the rooms varies greatly depending on the guest. If someone smokes, the pollution will be aggravated, while the pollution will be less when no one is staying. However, most existing air purification equipment has a fixed ventilation volume and cannot be adjusted according to real-time air quality. It either does not purify enough when the pollution is severe, resulting in a poor guest experience, or it runs excessively when the pollution is light, resulting in energy waste. At the same time, hotel rooms require frequent cleaning and maintenance of equipment. The cleaning of existing equipment filters often requires manual disassembly, which is time-consuming and labor-intensive, and the cleaning and brush replacement is complicated, affecting the turnover efficiency of the rooms.

[0009] Preferably, a ventilation opening is provided in the middle of the second mounting plate, and multiple movable plates are located on one side of the ventilation opening.

[0011] Preferably, a dual-axis motor is installed inside the rotating frame, with a fan blade fixedly connected to one end of the dual-axis motor and a worm gear fixedly connected to the other end of the dual-axis motor.

[0012] Preferably, the drive assembly includes a frame, which is fixedly connected to one end of the air outlet. A filter screen is installed inside the frame. A lead screw is rotatably connected to the bottom of the air outlet. A drive motor fixedly connected to the lead screw is installed on the side wall of the air outlet. A moving block is threadedly connected to the outer surface of the lead screw. A cleaning mechanism is installed on the side wall of the moving block.

[0013] Preferably, the cleaning mechanism includes a housing, a lifting rod slidably connected to the center of the housing, a drive rod rotatably connected to the top of the lifting rod, positioning rods slidably connected to both ends of the housing, a plug-in block fixedly connected to the top of the housing, and an installation block snapped into the top of the plug-in block.

[0015] Preferably, a locking block is fixedly connected to the top of the positioning rod, the top of the locking block is engaged with the outer edge of the bottom of the mounting block, and a cleaning brush is fixedly connected to the top of the mounting block.

[0016] A method for using a high-concentration negative oxygen ion device for optimizing air quality in hotel guest rooms includes the following steps:

[0017] Step 1, Air Purification and Ventilation Adjustment: The air inside the guest room enters the negative ion generator through the air inlet. The negative ion generator produces negative oxygen ions. According to the real-time air quality of the guest room, the cylinder drives the gear ring, which rotates under the constraint of the limit ring and drives the third gear to rotate. The third gear pulls the rack through the meshing force to drive the moving plate to move. The limit block on the right side of the moving plate is embedded in the limit hole, thereby adjusting the opening size of the ventilation opening.

[0018] Step 2, Enhanced Airflow Control and Purification Effect: One output shaft of the dual-axis motor drives the fan blades to rotate, while the other output shaft synchronously drives the worm gear to rotate. The worm gear drives the worm wheel to rotate, and the worm wheel drives the first rotating rod on the same axis to rotate. The first gear and the second gear at the bottom of the first rotating rod mesh to drive the second rotating rod to rotate. The second rotating rod drives the crank to make circular motion. The crank pulls the swing rod to swing around one end of the first mounting plate as the axis, thereby driving the rotating frame and the fan blades to swing synchronously. At the same time, the swing rod drives the rotating frame and the movable frame to adjust the angle.

[0019] Step 3: Cleaning and Component Maintenance After Equipment Shutdown: When the equipment is shut down, start the drive motor to rotate the lead screw, causing the moving block sleeved on the lead screw to move axially. The moving block drives the cleaning mechanism to clean the filter screen on the frame surface. When the cleaning brush needs to be replaced, rotate the threaded rod to raise and lower the lifting rod. The lifting rod pulls or pushes the drive rod to apply force to the two positioning rods simultaneously. With the cooperation of the side wall limiting groove and the limiting rod, the positioning rod adjusts with the threaded rod to achieve raising, lowering and rotating. After the mounting block and the plug-in block of the cleaning brush are engaged, the positioning rod descends and rotates, pressing the bottom end of the mounting block through the locking block at the top. Rotate the threaded rod in the opposite direction, and the positioning rod rises and rotates to disengage the locking block from the mounting block, allowing the cleaning brush to be removed.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, after air enters the negative ion generator through the air inlet, negative oxygen ions are stably generated, providing a basic guarantee for air purification. According to the real-time air quality of the guest room, the moving plate can be driven by a transmission structure such as a cylinder, a gear ring, and a third gear to precisely adjust the opening size of the ventilation opening. The moving plate is prevented from deviating by the cooperation of the limiting block and the limiting hole, ensuring that the air volume and negative oxygen ion concentration can be adjusted as needed. This design not only avoids the problem of insufficient purification or waste of resources under a fixed ventilation volume, but also provides a suitable purification solution for guest room environments with different pollution levels, improving the targeting and efficiency of air purification.

[0022] 2. In this invention, one end of the dual-axis motor directly drives the fan blades to rotate, accelerating the air circulation speed in the guest room and shortening the diffusion time of negative oxygen ions; the other end, through the linkage of components such as worm gear, worm wheel, and gear, drives the crank to make circular motion, which in turn pulls the swing rod to make the fan blades swing synchronously, while adjusting the angle between the rotating frame and the movable frame. The swing and angle adjustment of the fan blades break the limitation of fixed-direction air supply, allowing the airflow to cover all corners of the guest room more evenly, avoiding purification dead zones, greatly improving the contact range between air and negative oxygen ions, and further optimizing the uniformity of overall air circulation and purification.

[0023] 3. In this invention, starting the drive motor will move the cleaning mechanism along the lead screw to automatically clean the filter screen on the frame surface without manual disassembly. This quickly removes accumulated dust and impurities from the filter screen, preventing filter clogging from affecting subsequent ventilation and purification effects. At the same time, the cleaning brush replacement process is simple and efficient. By rotating the threaded rod, the positioning rod can be driven to rise and rotate, realizing the quick installation and removal of the cleaning brush. The positioning rod ensures precise operation through the cooperation of the limiting groove and the limiting rod. Maintenance can be completed without complicated tools. This convenient maintenance design reduces the difficulty and cost of daily equipment maintenance, reduces equipment failures caused by untimely maintenance, and ensures the long-term stability of the equipment.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Refer to Figure 1 - Figure 5 As shown: A high-concentration negative oxygen ion device for optimizing air quality in hotel guest rooms includes a negative ion generator 2 and a housing 3 fixedly connected to one side of it. An air inlet 1 is fixedly connected to one side of the negative ion generator 2. A sealing mechanism 7 is installed inside the housing 3. An air outlet 4 is fixedly connected to the side wall of the housing 3. A driving component 5 is installed at the bottom of the air outlet 4, and an air outlet mechanism 6 is installed inside the air outlet 4.

[0035] The closing mechanism 7 includes a second mounting plate 71. A limiting ring 74 is fixedly connected to the side wall of the second mounting plate 71. A toothed ring 72 is rotatably connected to the inner side of the limiting ring 74. Three third gears 76 are meshed with the inner side of the toothed ring 72. The third gears 76 are rotatably connected to the side wall of the second mounting plate 71. A plurality of limiting holes 77 are opened on the surface of the second mounting plate 71. A limiting block 751 is slidably connected inside the limiting holes 77. A moving plate 75 is fixedly connected to the side wall of the limiting block 751. A rack 752 is fixedly connected to one side of the moving plate 75. The rack 752 is meshed with the third gears 76.

[0036] The air outlet mechanism 6 includes a support block 61, a rotating frame 631 rotatably connected to the top of the support block 61, a movable frame 64 fixedly connected to one end of the rotating frame 631, a worm gear 65 rotatably connected to the inner side of the movable frame 64, a worm wheel 661 meshing with one side of the worm gear 65, a first rotating rod 66 fixedly connected to the inner surface of the worm wheel 661, the first rotating rod 66 rotatably connected to the movable frame 64, a first gear 662 fixedly connected to the outer surface of the bottom end of the first rotating rod 66, a second gear 671 meshing with one side of the first gear 662, and a second rotating rod 67 fixedly connected to the inner surface of the second gear 671.

[0037] A cylinder 73 is rotatably connected to the top of the side wall of the second mounting plate 71, and the output end of the cylinder 73 is rotatably connected to the side wall of the gear ring 72. A vent 78 is provided in the middle of the second mounting plate 71, and multiple movable plates 75 are located on one side of the vent 78.

[0038] In this embodiment, during the air purification process, the air inside the guest room is first guided into the negative ion generator 2 through the air inlet 1. During this process, the negative ion generator 2 generates negative oxygen ions through ionization. These negative oxygen ions can adsorb pollutants in the air, achieving air purification through sedimentation and decomposition reactions. To adapt to the air quality of different guest room environments, an automatic adjustment function for the vent 78 is designed. Based on real-time monitored air quality, the opening and closing degree of the vent 78 can be adjusted to ensure the efficient operation of the air purification process.

[0039] The adjustment mechanism is achieved through the cooperation of cylinder 73 and gear ring 72. Cylinder 73 drives gear ring 72 to move, and gear ring 72 rotates in an orderly manner under the control of limit ring 74. When gear ring 72 rotates, it applies a force to third gear 76, causing third gear 76 to start rotating. Third gear 76 meshes with rack 752 on one side, generating mechanical transmission force, thereby pushing moving plate 75 to move along the track. The movement of moving plate 75 changes the opening of vent 78, adjusting the airflow and the concentration of negative oxygen ions. During this process, limit block 751 on the right side of moving plate 75 is constrained by limit hole 77, ensuring that moving plate 75 does not deviate during movement, thus ensuring the accuracy and stability of the opening and closing action of vent 78.

[0040] In the air purification process, to accelerate airflow and improve air circulation efficiency, the rotation of fan blades 62 drives the airflow. The rotation of fan blades 62 is synchronized through mechanical transmission between worm gear 65 and worm wheel 661. During the rotation of worm wheel 661, it drives the first rotating rod 66 to rotate as well. The first gear 662 at the bottom of the first rotating rod 66 is connected to the second gear 671 through meshing force, further driving the second rotating rod 67 to rotate. The second rotating rod 67 is connected to crank 69, and the circular motion of crank 69 causes the swing rod 68 to swing along its axis, thereby driving the fan blades 62 to swing accordingly. This swing not only changes the direction of airflow but also, through precise control, optimizes airflow distribution and improves the air purification effect.

[0041] It can efficiently purify the air and flexibly adjust the airflow direction and volume according to different needs, ensuring that fresh and healthy air quality is maintained in different guest room environments. The coordinated operation of all components is key to ensuring efficient and stable operation of the air purification system.

[0042] Example 2: Figure 2 - Figure 5 As shown, a crank 69 is fixedly connected to the outer surface of the bottom end of the second rotating rod 67. A swing rod 68 is rotatably connected to one end of the crank 69, and a first mounting plate 611 is rotatably connected to one end of the swing rod 68. One end of the first mounting plate 611 is fixedly connected to the rotating frame 631. A dual-axis motor 63 is installed inside the rotating frame 631. A fan blade 62 is fixedly connected to one end of the dual-axis motor 63, and the other end of the dual-axis motor 63 is fixedly connected to one end of the worm gear 65.

[0043] In this embodiment, the dual-axis motor 63 plays a crucial role in the purification process, with its output shafts at both ends driving the fan blades 62 and the worm gear 65 to rotate, respectively. Specifically, the output shafts of the dual-axis motor 63 transmit power to the fan blades 62 and the worm gear 65 via mechanical connection. The rotation of the fan blades 62 accelerates airflow, effectively promoting air circulation and thus improving air circulation efficiency. In this process, the rotation of the fan blades 62 plays a vital role in increasing air velocity and improving air quality.

[0044] The rotation of the worm 65 is achieved through a series of precise gear transmissions, realizing a complex mechanical conversion. The worm 65 drives the worm wheel 661 to rotate, and the rotation of the worm wheel 661 further drives the precise transmission between the first gear 662 and the second gear 671. Through this gear transmission structure, the rotational kinetic energy of the worm wheel 661 is effectively converted into motion along different axes.

[0045] In this process, crank 69 converts the originally linear or rotational power into circular motion through gear transmission. This circular motion is used to drive swing arm 68, which converts the motion into a periodic oscillating force, thereby driving the movement of the integrated rotating frame 631 and the movable frame 64. In this way, the movable frame 64 can generate a certain displacement or change inside the purification equipment.

[0046] Example 3: According to Figure 6 - Figure 8 As shown, the drive assembly 5 includes a frame 54, which is fixedly connected to one end of the air outlet 4. A filter screen is installed inside the frame 54. A lead screw 53 is rotatably connected to the bottom of the air outlet 4. A drive motor 51, which is fixedly connected to the lead screw 53, is installed on the side wall of the air outlet 4. A moving block 52 is threadedly connected to the outer surface of the lead screw 53. A cleaning mechanism 8 is installed on the side wall of the moving block 52. The cleaning mechanism 8 includes a housing 83. A lifting rod 88 is slidably connected to the center of the housing 83. A drive rod 89 is rotatably connected to the top of the lifting rod 88. Positioning rods 85 are slidably connected to both ends of the housing 83. A plug-in block 831 is fixedly connected to the top of the housing 83. An installation block 82 is snapped into the top of the plug-in block 831. A threaded rod 84 is threadedly connected to the bottom of the housing 83. The top of the threaded rod 84 is rotatably connected to the bottom of the lifting rod 88. A slot 851 is provided at the bottom of the housing 83. One end of the drive rod 89 is engaged with the plug block 831. A limit groove 87 is provided on the side wall of the positioning rod 85. Limiting rods 86 that are slidably connected to the limit groove 87 are fixedly connected to both ends of the housing 83. A locking block 852 is fixedly connected to the top of the positioning rod 85. The top of the locking block 852 is engaged with the outer edge of the bottom end of the mounting block 82. A cleaning brush 81 is fixedly connected to the top of the mounting block 82.

[0047] In this embodiment, when the equipment is in a stopped state, dust and impurities in the air continuously accumulate on the surface of the equipment frame 54. To ensure stable ventilation and prevent dust blockage during long-term operation, an automated cleaning mechanism is employed. Power is provided by a drive motor 51, which rotates the lead screw 53, causing the moving block 52 connected to the lead screw 53 to move along its surface. The movement of the moving block 52 further drives the cleaning mechanism 8, periodically cleaning the filter screen on the surface of the frame 54, thereby effectively preventing ventilation blockage caused by dust and impurities accumulation.

[0048] To improve the cleaning effect of the cleaning brush 81, an adjustable positioning and replacement mechanism was designed. Specifically, when the cleaning brush needs to be replaced, the vertical movement of the lifting rod 88 can be adjusted by rotating the threaded rod 84. The rotation of the threaded rod 84 will cause the lifting rod 88 to move up and down, which in turn drives the drive rod 89 connected to the lifting rod 88 to move vertically together. During this process, the drive rod 89 will apply torque to the two positioning rods 85. By adjusting the rotation direction and rotation angle of the threaded rod 84, the positioning rods 85 can achieve precise lifting and lowering movements.

[0049] During the movement of the positioning rod 85, the interaction between the limiting groove 87 on its side wall and the limiting rod 86 constrains and precisely controls the movement of the positioning rod 85, thus ensuring that the positioning rod 85 not only moves vertically but also rotates during the lifting and lowering process. The rotational movement of the positioning rod 85 is achieved through the cooperation between the limiting groove 87 and the limiting rod 86. This design ensures the tight cooperation of all components of the equipment and reduces errors.

[0050] After the mounting block 82 and the insertion block 831 are engaged, the positioning rod 85 descends and rotates simultaneously. At this time, the locking block 852 located at the top of the positioning rod 85 applies pressure to the bottom outer surface of the mounting block 82, completing the precise positioning and fixation of the cleaning brush 81 and the mounting block 82. In this way, the cleaning brush 81 is reliably installed, enabling effective cleaning operations.

[0051] If the cleaning brush 81 needs to be replaced, simply reverse the operation: rotate the threaded rod 84 to raise and rotate the positioning rod 85, thereby loosening the connection between the locking block 852 and the mounting block 82, and completing the disassembly of the cleaning brush 81. This design not only makes the cleaning brush 81 easy to replace, but also greatly improves the convenience and efficiency of equipment maintenance, ensuring long-term stable operation of the equipment.

[0052] Example 4: A method for using a high-concentration negative oxygen ion device for optimizing air quality in hotel guest rooms, comprising the following steps:

[0053] 1) Air purification and ventilation adjustment: The air inside the guest room enters the negative ion generator 2 through the air inlet 1. The negative ion generator 2 generates negative oxygen ions. According to the real-time air quality of the guest room, the cylinder 73 drives the gear ring 72, which rotates under the constraint of the limit ring 74 and drives the third gear 76 to rotate. The third gear 76 pulls the rack 752 through the meshing force to drive the moving plate 75 to move. The limit block 751 on the right side of the moving plate 75 is embedded in the limit hole 77, thereby adjusting the opening size of the ventilation opening 78.

[0054] 2) Enhanced airflow control and purification effect: One output shaft of the dual-axis motor 63 drives the fan blade 62 to rotate, and the other output shaft synchronously drives the worm gear 65 to rotate. The worm gear 65 drives the worm wheel 661 to rotate. The worm wheel 661 drives the coaxial first rotating rod 66 to rotate. The first gear 662 at the bottom of the first rotating rod 66 meshes with the second gear 671 to drive the second rotating rod 67 to rotate. The second rotating rod 67 drives the crank 69 to perform circular motion. The crank 69 pulls the swing rod 68 to swing around one end of the first mounting plate 611 as the axis, thereby driving the rotating frame 631 and the fan blade 62 to swing synchronously. At the same time, the swing rod 68 drives the rotating frame 631 and the movable frame 64 to adjust the angle.

[0055] 3) Cleaning and component maintenance after equipment shutdown: When the equipment is shut down, start the drive motor 51 to drive the lead screw 53 to rotate, so that the moving block 52 sleeved on the lead screw 53 moves axially. The moving block 52 drives the cleaning mechanism 8 to clean the filter screen on the surface of the frame 54. When the cleaning brush 81 needs to be replaced, rotate the threaded rod 84 to drive the lifting rod 88 to rise and fall. The lifting rod 88 pulls or pushes the drive rod 89 to apply force to the two positioning rods 85 simultaneously. With the cooperation of the side wall limiting groove 87 and the limiting rod 86, the positioning rod 85 adjusts with the threaded rod 84 to achieve rising, falling and rotating. After the mounting block 82 of the cleaning brush 81 is engaged with the plugging block 831, the positioning rod 85 descends and rotates. The locking block 852 at the top presses the bottom end of the mounting block 82, and the threaded rod 84 is rotated in the opposite direction. The positioning rod 85 rises and rotates to make the locking block 852 disengage from the mounting block 82, and the cleaning brush 81 is removed.

[0056] The device's operation and working principle are as follows: During guest room air purification, air enters the negative ion generator 2 through the air inlet 1, generating negative oxygen ions to purify the air. The opening size of the vent 78 can be adjusted according to air quality. The cylinder 73 drives the gear ring 72, which rotates under the restriction of the limiting ring 74 and drives the third gear 76 to rotate. The third gear 76 drives the moving plate 75 to move through the rack 752. The limiting block 751 cooperates with the limiting hole 77 to prevent deviation, thereby adjusting the vent 78 to control the air volume and the amount of negative oxygen ions. The output shafts at both ends of the dual-shaft motor 63 drive the fan blades 62 and the worm gear 65 to rotate respectively. The fan blades 62 accelerate air circulation, and the worm gear 65 drives the worm wheel 661 to rotate. Through the transmission of the first gear 662 and the second gear 671, the circular motion of the crank 69 is converted into the swing of the swing arm 68. The fan blades 62 swing with the rotating frame 631 to change the airflow direction and improve the purification effect. When the equipment is stopped, dust easily accumulates on the surface of the frame 54. The drive motor 51 drives the lead screw 53 to rotate, causing the moving block 52 to drive the cleaning mechanism 8 to clean the filter screen and prevent clogging. The cleaning brush 81 can be positioned and replaced. The threaded rod 84 drives the lifting rod 88 and the drive rod 89 to drive the positioning rod 85 to rise and fall. The limit groove 87 cooperates with the limit rod 86 to make the positioning rod 85 rotate when it rises and falls. After the mounting block 82 and the plug-in block 831 are engaged, the positioning rod 85 descends and rotates. The locking block 852 positions the mounting block 82 and the cleaning brush 81. Conversely, it can be disassembled and replaced.

[0057] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

8. A method for using a high-concentration negative oxygen ion device for optimizing air quality in hotel guest rooms, characterized in that... The high-concentration negative oxygen ion device for optimizing air quality in hotel rooms according to any one of claims 1-7 comprises the following steps: S1. Air purification and ventilation adjustment: The air inside the guest room enters the negative ion generator (2) through the air inlet (1). The negative ion generator (2) generates negative oxygen ions. According to the real-time air quality of the guest room, the gear ring (72) is driven by the cylinder (73) to rotate under the constraint of the limiting ring (74) and drive the third gear (76) to rotate. The third gear (76) pulls the rack (752) through the meshing force to drive the moving plate (75) to move. The limiting block (751) on the right side of the moving plate (75) is embedded in the limiting hole (77), thereby adjusting the opening size of the ventilation opening (78). S2. Enhanced airflow control and purification effect: The output shaft of the dual-axis motor (63) drives the fan blade (62) to rotate, and the output shaft of the other end drives the worm (65) to rotate synchronously. The worm (65) drives the worm wheel (661) to rotate. The worm wheel (661) drives the first rotating rod (66) on the same axis to rotate. The first gear (662) at the bottom of the first rotating rod (66) meshes with the second gear (671) to drive the second rotating rod (67) to rotate. The second rotating rod (67) drives the crank (69) to make a circular motion. The crank (69) pulls the swing rod (68) to swing around the first mounting plate (611) as the axis, thereby driving the rotating frame (631) and the fan blade (62) to swing synchronously. At the same time, the swing rod (68) drives the rotating frame (631) and the movable frame (64) to adjust the angle. S3. Cleaning and component maintenance after equipment shutdown: When the equipment is shut down, start the drive motor (51) to drive the lead screw (53) to rotate, so that the moving block (52) sleeved on the lead screw (53) moves axially. The moving block (52) drives the cleaning mechanism (8) to clean the filter screen on the surface of the frame (54). When the cleaning brush (81) needs to be replaced, rotate the threaded rod (84) to drive the lifting rod (88) to rise and fall. The lifting rod (88) pulls or pushes the drive rod (89) to simultaneously apply pressure to the two positioning rods (85). With the application of force, the positioning rod (85) is adjusted by the threaded rod (84) in conjunction with the side wall limiting groove (87) and the limiting rod (86) to achieve lifting and rotation. After the mounting block (82) of the cleaning brush (81) is engaged with the plug-in block (831), the positioning rod (85) descends and rotates, and the bottom end of the mounting block (82) is pressed by the locking block (852) at the top. The threaded rod (84) is rotated in the opposite direction, and the positioning rod (85) rises and rotates to make the locking block (852) disengage from the mounting block (82), and the cleaning brush (81) is removed.
