Description

Technical Field

[0001] The utility model relates to the technical field of humidifiers, in particular to a locking system on a humidifier. Background Art

[0002] There are many types of humidifiers. The working principle of one type of humidifier is to use flowing air to pass through a gauze with a high moisture content to increase the air humidity. For this type of humidifier, increasing the moisture temperature in the gauze can effectively improve the humidification efficiency. Based on this, a heating plate assembly can be added near the humidifying mesh assembly to provide a heat source for the moisture in the gauze.

[0003] It was found in actual work that the humidifying net assembly needs to be frequently disassembled, wiped and maintained, and the heating plate assembly needs to be disassembled when the humidifying net assembly is disassembled; when the humidifier is working, the heating plate assembly needs to ensure a firm connection without any movement. Based on this, a locking system is needed that can be securely locked and unlocked for disassembly, so that the heating plate assembly can be quickly, securely and reversibly locked to the body casing.

[0004] Due to the above reasons, the inventor has conducted in-depth research on the lock structure in the existing humidifier, hoping to design a new lock system on the humidifier that can solve the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned problems, the inventors have conducted intensive research and designed a locking system on a humidifier, in which a switch extending upward from the heating disk assembly is provided in the locking system. Turning the switch can drive the rotating shaft to rotate, and further drive the waist plate on the rotating shaft to rotate. A connecting rod is hinged on the waist plate, and the connecting rod is connected to the locking tongue, so as to control the locking tongue to extend outward into the card slot to complete the locking, or retract into the outer shell of the heating disk assembly to release the lock, thereby completing the utility model.

[0006] Specifically, the purpose of the utility model is to provide a locking system on a humidifier, wherein the humidifier includes a body shell 1, in which a heating plate assembly 3 is arranged; the locking system is arranged in the heating plate assembly 3, and the heating plate assembly 3 is quickly, firmly and reversibly locked on the body shell 1 through the locking system.

[0007] The locking system includes a switch 41 and a locking tongue 42.

[0008] One end of the switch 41 extends out of the outer shell of the heating disk assembly 3. By toggling the switch 41, the locking tongue 42 is controlled to extend from the outer shell of the heating disk assembly 3 and extend into the card slot 11 of the body shell 1, thereby completing the locking of the heating disk assembly 3.

[0009] Among them, Figure 5As shown in the figure, the latch system further includes a rotating shaft 43. The switch 41 is arranged at one end of the rotating shaft 43, and the switch 41 can drive the rotating shaft 43 to rotate synchronously around the axis of the rotating shaft 43;

[0014] Among them, on the switch 41, a sliding groove 5 and two limiting pits 6 are formed by inward depression around the rotating shaft 43,

[0015] An arc-shaped protrusion is arranged on the housing of the heating plate assembly 3. The protrusion can be embedded into the sliding groove 5 or the limiting pit 6. The cooperation between the protrusion and the limiting pit 6 provides limit for the switch 41 to avoid accidental unlocking.

[0016] Among them, the rotating shaft 43 is fixed to the middle of the waist-shaped plate 44. Connecting rods 45 are hinged at the two side edges of the waist-shaped plate 44, that is, two connecting rods 45 and locking tongues 42 are provided, so as to lock the heating plate assembly 3 synchronously on both sides.

[0017] Among them, a pressing plate 411 is arranged at the top of the switch 41 to increase the toggling area of the switch 41 through the pressing plate 411.

[0018] Among them, the outer contour of one end of the rotating shaft 43 is set as a square tube. Correspondingly, a square hole 412 capable of accommodating the square tube is opened on the switch 41. The cooperation between the square tube and the square hole 412 enables the switch 41 to drive the rotating shaft 43 to rotate synchronously.
