Description

Technical Field

[0001] This invention relates to a humidifier. Background Technology

[0002] The existing technology, Chinese patent 202120346263.3, describes a top-filled humidifying floor fan, including a chassis, a riser, a control box, a fan head, a humidifier mounted on the chassis, and a mist guide pipe connecting the humidifier and the fan head. The water tank cover includes a curved cavity with an upper opening, a water inlet cavity on the bottom plate of the curved cavity, an annular interface on the bottom plate inside the water inlet cavity, and a mist guide interface on the bottom plate outside the water inlet cavity, with water inlet holes surrounding the annular interface. It also includes a top cover with a mist guide pipe seat. The mist guide pipe is inserted into and fixed together with the mist guide pipe seat, which is inserted into the annular interface. There is a gap between the top cover and the curved cavity, and the area of ​​the top cover is smaller than the area of ​​the water tank cover. Figure 1 , Figure 6 As shown in Figure 7, the mist guide tube passes between the two vertical pipes at the bottom of the control box, fits into the groove at the rear of the control box, then passes through the through hole at the top of the control box, and finally connects to the fan head. The problem is that the length of the mist guide tube suspended in the air is too large. Summary of the Invention

[0003] The purpose of this invention is to provide an improved floor fan with a short suspended length of the mist guide tube and a secure fixation.

[0004] The present invention is implemented as follows: an improved floor fan with a fixed mist guide tube, comprising a chassis, a vertical tube, a control box, a fan head, a mist guide tube, and a humidifier, wherein the control box comprises a front box body with a rear opening and a rear box body with a front opening, characterized in that: the upper part of the front box body is provided with a front tube outlet and the lower part is provided with a front tube inlet, and the rear box body is provided with a groove with a rear opening, the lower part of the groove is provided with a rear tube outlet and the upper part is provided with a rear tube inlet;

[0005] The mist guide tube enters the control box through the front tube inlet, enters the groove through the rear tube outlet and fits into the groove, enters the control box through the rear tube inlet, and extends out of the control box through the front tube outlet.

[0006] The improved floor fan with a fixed mist guide tube is characterized in that the mist guide tube slides and is positioned in conjunction with the front tube inlet, the rear tube outlet, the groove, the rear tube inlet, and the front tube outlet.

[0007] This invention relates to an improved method for fixing a mist guide tube in a floor fan. The length of the mist guide tube can be adjusted at the top and bottom of the control box, and it is securely fixed. Attached Figure Description

[0014] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0015] like Figure 1 , Figure 2 As shown, a floor fan includes a chassis 1, a vertical pipe 2, a control box 3, a fan head 4, a mist guide pipe 5, and a humidifier 6. The control box 3 includes a front box 31 with a rear opening and a rear box 32 with a front opening. The structure of the humidifier 6, control box 3, and fan head 4 is such that the fan head 4 is connected to the control box 3. The connection method of the mist guide pipe 5 to the humidifier and the fan head is disclosed in Chinese Patent 202120346263.3, entitled "A Floor Fan with Top-Filled Water Humidification". This application only makes further improvements to the fixing method of the mist guide pipe 5.

[0016] The front box 31 has a front tube outlet 311 at the top and a front tube inlet 312 at the bottom. The rear box 32 has a groove 321 with a rear opening, a rear tube outlet 322 at the bottom and a rear tube inlet 323 at the top.

[0017] The mist guide tube 5 enters the control box 3 through the front tube inlet 312, enters the groove 321 through the rear tube outlet 322 and fits into the groove 321, enters the control box 3 through the rear tube inlet 323, extends out of the control box 3 through the front tube outlet 311, and then connects to the fan head 4. With this structure, the length of the mist guide tube 5 at the top and bottom of the control box 3 can be adjusted.

[0018] The mist guide tube 5 is slidably engaged and positioned with the front tube inlet 312, the rear tube outlet 322, the groove 321, the rear tube inlet 323, and the front tube outlet 311. With this structure, adjusting the lengths of the upper mist guide tube 51 and the lower mist guide tube 52 of the control box 3 is easy. The front tube inlet 312, the rear tube outlet 322, the groove 321, the rear tube inlet 323, and the front tube outlet 311 prevent displacement of the mist guide tubes; moreover, adjustment is convenient.

[0019] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
