Description

Technical Field

[0001] The utility model relates to a humidifier, in particular to a mist outlet structure of a humidifier. Background Art

[0002] The patent document with publication number CN208936399U discloses a humidifier with an externally controlled adjustable nozzle angle, wherein the exhaust nozzle comprises two parts, one is a hard nozzle and the other is a bellows. The tail end of the hard nozzle is connected to one end of the bellows, and the other end of the bellows is fixedly plugged into the tail end of the exhaust channel. During actual use, the end of the bellows connected to the exhaust channel is easily deformed, causing the bellows to fall off. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a mist outlet structure for a humidifier.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A humidifier mist outlet structure comprises a main unit, a connecting piece and a bellows, wherein the main unit is provided with a mist outlet, the lower end of the connecting piece is connected to the mist outlet, and the upper end is threadedly connected to the lower end of the bellows.

[0006] As a further improvement of the utility model, the inner wall of the upper end of the connecting piece is provided with an internal thread, and the bellows has a spiral concave-convex structure. After the lower end of the bellows is inserted into the connecting piece, the bellows is twisted, and the internal thread and the concave-convex structure of the bellows are threadedly engaged to form a threaded connection.

[0007] As a further improvement of the present invention, a thread groove is provided at a position of the outer wall of the connecting piece corresponding to the internal thread.

[0008] Furthermore, the connecting piece is composed of a connecting pipe and a fixed pipe located at the lower end of the connecting pipe, the internal thread is located on the inner wall of the connecting pipe, the outer diameter of the connecting pipe is larger than the outer diameter of the fixed pipe, and an external step is formed between the connecting pipe and the fixed pipe.

[0009] Furthermore, the inner diameter of the connecting pipe is larger than the inner diameter of the fixing pipe, and an inner step is formed between the connecting pipe and the fixing pipe.

[0010] Furthermore, a positioning protrusion is provided on the inner wall of the connecting piece fixing tube.

[0011] The beneficial effects of the utility model are as follows: the utility model installs a bellows on the main machine, and the bellows can be stretched and compressed. After stretching, the spray distance is farther, and after compression, the length is shorter, which can save packaging cost and transportation cost; the lower end of the bellows is connected to the connecting piece by a knob thread fixing method, and the connection is firm and reliable, which effectively avoids the problem of falling off between the connecting piece and the bellows.

[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0017] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0018] Reference Figures 1 to 3 A humidifier mist outlet structure comprises a main unit, a connector 2 and a bellows 1, wherein the main unit is provided with a mist outlet, the lower end of the connector 2 is connected to the mist outlet, and the upper end is threadedly connected to the lower end of the bellows 1; in this embodiment, a bellows is installed on the main unit, and the bellows can be stretched and compressed. After stretching, the spray distance is farther, and after compression, the length is shorter, which can save packaging costs and transportation costs; the lower end of the bellows is connected and fixed to the connector by threading, and the connection is firm and reliable, which effectively avoids the problem of the connector and the bellows falling off.

[0019] The inner wall of the upper end of the connector 2 is provided with an internal thread 21, and the bellows has a spiral concave-convex structure. After the lower end of the bellows 1 is inserted into the connector 2, the bellows is twisted, and the internal thread 21 is engaged with the concave-convex structure of the bellows to form a threaded connection. Of course, a thread can also be provided on the outer wall of the upper end of the connector 2 so that the upper end of the connector is inserted into the bellows, which can also be fixed in a threaded connection.

[0020] The outer wall of the connector 2 is provided with a thread groove 22 at a position corresponding to the internal thread 21; the thread groove can prevent the connector from shrinking after injection molding due to excessive wall thickness of the connector.

[0021] The connecting piece 2 is composed of a connecting pipe and a fixed pipe located at the lower end of the connecting pipe. The internal thread 21 is located on the inner wall of the connecting pipe. The outer diameter of the connecting pipe is larger than the outer diameter of the fixed pipe. An external step is formed between the connecting pipe and the fixed pipe. After the connecting piece is installed at the upper end of the humidifier, the external step acts as a limit to abut against the lower end surface of the connecting pipe at the upper part of the connecting piece.

[0022] The inner diameter of the connecting pipe is larger than that of the fixed pipe, and an internal step 23 is formed between the connecting pipe and the fixed pipe. After the bellows is screwed into the connecting piece, the lower end face of the bellows is against the internal step; the fixed pipe of the connecting piece is inserted into the mist outlet of the humidifier.

[0023] The inner wall of the connector fixing tube is provided with a positioning protrusion, and during injection molding, the injection molding machine is positioned by the positioning protrusion.
