Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, and in particular to a humidifier rotor assembly. Background Technology

[0002] Humidifiers are electrical appliances widely used in homes, offices, and other environments. Their main function is to increase indoor humidity, thereby improving the comfort of residents. The rotating wheel assembly is an important component of the humidifier, used to agitate the water in the tank so that the water comes into contact with the air, thus regulating indoor humidity.

[0003] A search revealed Chinese patent CN222364051U, which discloses a rotating wheel assembly comprising: an inner frame, including a first frame and a second frame; a first side of the first frame having multiple first posts, each with a first insertion hole; and two sides of the second frame having multiple second posts, each with a second insertion hole, with each second insertion hole corresponding to a first insertion hole; furthermore, the first sides of the two first frames are arranged opposite each other, and multiple second frames are disposed between the two first frames; wherein each set of corresponding first and second insertion holes is connected by a pin, thereby connecting the two first frames and the multiple second frames. Thus, the inner frame is assembled from the first and second frames, and the number of second frames can be flexibly adjusted according to the actual application scenario, thereby adjusting the length of the inner frame. This application also discloses a humidifier.

[0004] The aforementioned components lack a limiting mechanism after extension. Without an effective limiting mechanism, the rotor assembly may retract on its own due to its own weight, equipment vibration, or slight contact during use, failing to maintain the preset working length. This affects the matching accuracy between the humidifier and the rotor assembly, resulting in decreased humidification efficiency and unstable humidification range. On the other hand, the lack of a limiting mechanism makes it difficult to precisely control the extension length of the components. The length is prone to deviation after each adjustment, making it unable to adapt to the specific requirements of the rotor assembly length under different spaces or different humidification needs. Utility Model Content

[0005] The purpose of this utility model is to provide a rotor assembly for a humidifier that solves the problem of the lack of a limiting mechanism after the above-mentioned assembly extends. Without an effective limiting mechanism, the rotor assembly may retract on its own due to its own weight, equipment vibration, or slight touch during use, making it unable to maintain the preset working length. This affects the matching accuracy between the humidifier and the rotor assembly, resulting in decreased humidification efficiency and unstable humidification range. On the other hand, without a limiting mechanism, it is difficult to accurately control the extension length of the assembly. The length is prone to deviation after each adjustment, making it unable to adapt to the specific requirements of the rotor assembly length under different spaces or different humidification needs.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a humidifier rotor assembly, including an inner frame, and further comprising: An outer frame is disposed on the outside of the inner frame, and the outer frame is symmetrically disposed on the outside of the inner frame; End caps are disposed on the outer sides of both ends of the inner frame; Insert rods are disposed on the inner side of the inner frame, and the insert rods are distributed in a ring on one side of the inner frame; A sleeve is fixedly installed on one side of the inner frame, and the insert rod moves laterally inside the sleeve. A connector is provided on one side of the inner frame; A sliding sleeve is disposed on the inner side of the inner frame; A sliding rod is slidably disposed on the inner side of the sliding sleeve, and the sliding rod moves laterally on the inner side of the sliding sleeve; A limiting member is disposed on the inner side of the inner frame, and the limiting member is used to limit the position of the slide rod on the inner side of the slide sleeve.

[0007] In a preferred embodiment, the limiting rod is fixedly disposed on the outer sides of both ends of the insertion rod; A limiting groove is formed on the inner side of the end of the sleeve, and a limiting rod is disposed on the inner side of the limiting groove.

[0008] In a preferred embodiment, two handles are fixedly provided on the inner side of the end of the inner frame.

[0009] Its specific advantages are: the length can be increased by pulling the inner frame with the handle, and the length adjustment is smooth and precise by using the sliding of the plug rod inside the plug sleeve and the limiting rod to limit the movement trajectory of the plug rod.

[0010] In a preferred embodiment, a slot is formed on the inner side of the end of the sliding sleeve, and the slots are evenly distributed along the axial direction of the sliding sleeve; A rotating arm is rotatably mounted on one side of the slide bar; The snap-fit ​​connector is fixedly installed on the outer side of the end of the rotating arm.

[0011] In a preferred embodiment, a stop plate is fixedly disposed on the inner side of the end of the slide rod, and the stop plate is made of an elastic material; A groove is formed on the inner side of the end of the rotating arm, and the end of the abutment plate abuts against the inner side of the groove.

[0012] In a preferred embodiment, the end of the abutment plate is configured with an L-shaped structure to increase the supporting force on the abutment groove.

[0013] In a preferred embodiment, a groove is provided on the inner side of the end of the rotating arm, and the L-shaped structure at the end of the abutment plate engages with the groove.

[0014] In a preferred embodiment, the inner side of the card slot is provided with a setting structure and an arc-shaped structure, which are used to limit the position of the card connector.

[0015] Its specific advantages are as follows: the slide rod slides inside the slide sleeve, the snap-fit ​​connector can be snapped into the inside of the snap-fit ​​groove, and the support of the abutment plate on the abutment groove enables the rotating arm to maintain rotational force, which can effectively prevent the inner skeleton from shrinking on its own after stretching, and ensure the length is stable after adjustment.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This humidifier rotor assembly boasts significant advantages in terms of ease of length adjustment and post-adjustment stability, flexibly adapting to various usage needs. The outer frame and end cap are fixed to the outside of the inner frame for stable operation with the humidifier. Users can increase its length by pulling the inner frame with a handle. During this process, the sliding rod inside the sleeve and the limiting rod restricting the rod's movement trajectory ensure smooth and precise length adjustment. When adjusting the length, the sliding rod slides inside the sleeve, and the locking connector engages inside the slot. The support plate against the slot maintains the rotational force of the rotating arm, effectively preventing the inner frame from retracting after stretching and ensuring stable length after adjustment. When it is necessary to retract the inner frame, simply pull it to its longest length so that the locking connector engages inside the end of the sleeve. This will rotate the rotating arm and limit the angle, causing the locking connector to disengage from the slot. Then, push the sliding rod back inside the sleeve. When pushed to the end, the rotating arm rotates downwards, allowing the support plate to engage the slot again. The entire telescopic adjustment process requires no complicated operation, balancing flexibility and stability to meet the usage needs of humidifiers in different scenarios.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please see Figure 1 - Figure 6 This embodiment provides a humidifier rotor assembly with easily adjustable length, the specific idea of ​​which is as follows: A humidifier rotor assembly includes an inner frame 1, an outer frame 101, and an end cap 102. The humidifier rotor assembly also includes a plug rod 2 and a connector.

[0021] The inner frame 1 has symmetrically distributed outer frames 101 on its outer side. Together, they form the support frame of the rotating wheel assembly, providing an installation base for the moisture-absorbing material of the humidifier. The inner frame 1 has end caps 102 on its outer sides at both ends, which can close the ends of the frame to prevent the internal material from falling off, and at the same time form an airflow channel to guide the airflow during the humidification process. The inner frame 1 has telescopic insertion rods 2 on its inner side. Multiple insertion rods 2 are distributed in a ring along one side of the inner frame 1 and are inserted into the inner side of the sleeve 201 fixedly connected to one side of the inner frame 1. The insertion rods 2 can move laterally along the inner side of the sleeve 201 and the length can be changed by telescopic adjustment. A connector is provided on one side of the inner frame 1.

[0022] As examples, in this embodiment, the connector includes a limiting rod 202 and a limiting groove 203.

[0023] Among them, the outer sides of both ends of the insertion rod 2 are fixedly connected with limiting rods 202 for limiting its movement trajectory, and the inner side of the end of the sleeve 201 is provided with a matching limiting groove 203, and the limiting rod 202 is placed inside the limiting groove 203. When the insertion rod 2 extends or retracts laterally along the insertion sleeve 201, the limiting rod 202 will slide synchronously along the limiting groove 203 to constrain the movement direction of the insertion rod 2 and prevent the insertion rod 2 from deviating during the extension and retraction process. Two handles 204 that provide assistance are fixedly connected to the inner side of the end of the inner frame 1. When adjusting the extension and retraction of the insertion rod 2, the handles 204 can provide reverse support force, which makes it easy to apply force to push the insertion rod 2 to move.

[0024] It should be noted that this structure ensures the stability of the extension and retraction adjustment of the plug rod 2 through the trajectory constraint of the limiting rod 202 and the limiting groove 203, ensuring the stable operation of the rotor during humidification, and reducing the operational threshold for assembly and maintenance.

[0025] Example 2: Please see Figure 1 - Figure 6 This embodiment provides a humidifier rotor assembly that facilitates length limitation, and its specific concept is as follows: A humidifier rotor assembly includes an inner frame 1, an outer frame 101, and an end cap 102. The humidifier rotor assembly also includes a sliding sleeve 3 and a limiting member.

[0026] The inner frame 1 has a sliding sleeve 3 for support on its inner side, which serves as the mounting base for the sliding rod 301. The sliding rod 301, which plays a supporting role, is slidably connected to the inner side of the sliding sleeve 3 and can move laterally along the sliding sleeve 3. The inner frame 1 has a limiting member for limiting the position of the sliding rod 301.

[0027] As some examples, in this embodiment, the limiting element includes: a slot 302 and a rotating arm 303.

[0028] Among them, the inner side of the end of the sliding sleeve 3 is provided with a slot 302 that serves as a limit. The slots 302, which are evenly distributed along the axis of the sliding sleeve 3, provide multiple adjustment levels for the positioning of the sliding rod 301. The inner side of the slot has both a straight groove structure and an arc structure. It should be noted that the straight groove section facilitates the quick insertion of the snap-fit ​​connector 304, while the arc-shaped structure provides circumferential constraint on the snap-fit ​​connector 304 to prevent it from accidentally dislodging and ensure that the slide rod 301 is stable in position after adjustment.

[0029] Meanwhile, a rotating arm 303 that provides locking and support is rotatably connected to one side of the slide rod 301. The locking connector 304 fixedly connected to the outer end of the arm can rotate with the rotating arm 303 to lock or disengage from the locking slot 302. When the slide rod 301 needs to be fixed, the rotating arm 303 is rotated to make the locking connector 304 lock into the corresponding locking slot 302. When adjusting the length, the rotating arm 303 is rotated in the opposite direction to make the locking connector 304 disengage from the locking slot 302, which can push the slide rod 301 to move. The operation is convenient and the positioning is reliable.

[0030] In addition, an elastic material abutment plate 306 is fixedly connected to the inner side of the end of the slide bar 301. Its L-shaped end structure cooperates with the abutment groove 307 and pull groove 305 on the inner side of the rotating arm 303 to form a double limit: when the end of the abutment plate 306 abuts against the abutment groove 307, it can restrict the free rotation of the rotating arm 303 and prevent the snap-fit ​​connector 304 from accidentally coming loose during vibration. When the rotating arm 303 is rotated, the L-shaped structure engages with the groove 305, providing clear gear feedback for the rotation action and enhancing the engagement force through the elastic tension of the abutment plate 306. This ensures that the rotating arm 303 remains stably in the working position and forms a coordinated support with the telescopic system of the insertion rod 2, further improving the structural adjustability and operational stability of the rotary assembly and ensuring that the humidifier maintains high-efficiency humidification performance during long-term use.

[0031] Working principle: When using the device, the outer frame 101 and end cap 102 are fixed to the outside of the inner frame 1 and work in conjunction with the humidifier. When the user needs to adjust the length of the inner frame 1, the user can pull the inner frame 1 through the handle 204 to increase the length of the inner frame 1. At this time, the insertion rod 2 slides inside the insertion sleeve 201, and the two ends of the insertion rod 2 slide inside the insertion sleeve 201, thereby increasing the length of the inner frame 1. At the same time, the limiting rod 202 slides inside the limiting groove 203, which can limit the movement trajectory of the insertion rod 2. When the length of the inner frame 1 is increased by pulling, the sliding rod 301 will slide inside the sliding sleeve 3. At this time, the abutment plate 306 abuts against the inside of the abutment groove 307, thereby causing the snap-fit ​​connector 304 on one side of the rotating arm 303 to snap into the inside of the snap-fit ​​groove 302. When the sliding rod 301 is pulled, the snap-fit ​​connector 304 disengages from the arc-shaped structure on one side of the snap-fit ​​groove 302 and snaps into the next snap-fit ​​groove 302. Under the support of the abutment plate 306, the rotating arm 303 always maintains rotational force, which can prevent the inner frame 1 from shrinking after stretching. When the user wants to shrink the inner frame 1, he only needs to pull the inner frame 1 to its longest length, so that the rotating arm 303 moves to the end of the sliding sleeve 3. At this time, the snap joint 304 at the end of the rotating arm 303 snaps into the inner side of the end of the sliding sleeve 3, and at the same time drives the rotating arm 303 to rotate, thereby snapping the L-shaped structure at the end of the abutment plate 306 into the inner side of the pull groove 305, thereby limiting the angle of the rotating arm 303, and at the same time disengaging the snap joint 304 from the inner side of the snap groove 302, thereby pushing the slide rod 301 back to the inner side of the sliding sleeve 3 until the rotating arm 303 is pushed to the other end of the sliding sleeve 3. At this time, the rotating arm 303 abuts against the inner side of the end of the sliding sleeve 3, forcing the rotating arm 303 to rotate downward, so that the end of the abutment plate 306 disengages from the inner side of the pull groove 305, and the abutment plate 306 abuts against the inner side of the abutment groove 307 again.

[0032] The humidifier rotor assembly offers significant advantages in terms of ease of length adjustment and stability after adjustment, flexibly adapting to different usage needs. The outer frame 101 and end cap 102 are fixed to the outside of the inner frame 1, ensuring stable operation of the humidifier. Users can increase the length by pulling the inner frame 1 with the handle 204. During this process, the insertion rod 2 slides inside the insertion sleeve 201, and the limiting rod 202 limits the movement trajectory of the insertion rod 2, ensuring smooth and precise length adjustment. When adjusting the length, the sliding rod 301 slides inside the sliding sleeve 3, and the locking connector 304 can be engaged inside the locking groove 302, with the abutment plate 306 supporting the abutment groove 307. Maintaining the rotational force of the rotating arm 303 effectively prevents the inner frame 1 from shrinking on its own after stretching, ensuring stable length after adjustment. When it is necessary to shrink the inner frame 1, simply pull it to its longest length so that the locking connector 304 engages with the inner side of the end of the sliding sleeve 3. This will drive the rotating arm 303 to rotate and limit the angle, causing the locking connector 304 to disengage from the locking groove 302. This will then push the sliding rod 301 back to the inner side of the sliding sleeve 3. When pushed to the end, the rotating arm 303 rotates downwards, allowing the abutment plate 306 to abut against the abutment groove 307 again. The entire telescopic adjustment process requires no complicated operation, balancing flexibility and stability, and adapting to the usage needs of humidifiers in different scenarios.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
