Description

Technical Field

[0001] This utility model relates to the field of electric fan technology, and in particular to an electric fan structure that is easy to disassemble and assemble. Background Technology

[0002] An electric fan, also known as a fan or air ventilator, is a household appliance that uses an electric motor to drive the fan blades to rotate, thereby accelerating air circulation. It is mainly used for cooling and ventilating the air. Electric fans are relatively inexpensive, have low operating costs, and are easy to move, allowing them to be used in different rooms as needed. Their wind speed and air volume are adjustable, meeting the needs of different seasons and scenarios. In addition, electric fans are relatively safe to use, and when used correctly, they generally do not cause harm to the human body.

[0003] After a period of use, the blades and outer protective cover of existing electric fans tend to accumulate a lot of dust. The increased dust reduces the airflow speed, so regular disassembly and cleaning are necessary. However, the outer protective cover of current electric fans is usually fixed by locking sleeves and tightening bolts, requiring the use of professional tools for disassembly and assembly, making the process cumbersome. Furthermore, the protective cover is usually molded in one piece. To better protect against children's fingers or foreign objects from being inserted, the front air outlet of the protective cover is usually more tightly sealed. This results in small and dense ventilation gaps in the protective cover, greatly increasing the difficulty of subsequent cleaning. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Currently, after a period of use, the fan blades and external protective cover of electric fans tend to accumulate a lot of dust. The increase in dust reduces the airflow speed, thus requiring regular disassembly and cleaning. However, the external protective cover of current electric fans is usually fixed by locking sleeves and tightening bolts, requiring the use of specialized tools for disassembly and assembly, making the process cumbersome. Furthermore, current protective covers are usually one-piece molded. To better protect against children's fingers or foreign objects from entering, the seal at the front air outlet is usually larger, resulting in smaller and denser ventilation gaps, greatly increasing the difficulty of subsequent cleaning.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An electric fan structure that is easy to disassemble and assemble includes a front protective cover and a rear protective cover. The opposing surfaces of the front and rear protective covers are in contact with each other. The rear protective cover is provided with a convenient disassembly mechanism, which includes an annular mounting block, a movable rod, a limiting post, and a support spring. The convenient disassembly mechanism facilitates the disassembly and cleaning of the front and rear protective covers.

[0007] The front protective cover is equipped with an interleaved protection mechanism, which includes an annular baffle plate, a limiting slider, a screw, and a threaded rotating block. The interleaved protection mechanism enables ventilation by interleaving gaps with the front protective cover, increasing the gap spacing and reducing the density, which facilitates subsequent cleaning.

[0008] Preferably, the annular mounting block is sleeved on the outside of the rear protective cover, the two movable rods are slidably inserted into the movable holes opened in the annular mounting block, the two movable holes are symmetrically distributed on one side surface of the annular mounting block, and the support spring is sleeved on the outside of the movable rods.

[0009] Preferably, one end of each of the two support springs is fixedly connected to one side surface of the annular mounting block, the other end of the support spring is fixedly connected to a pressing block, and the other end of the movable rod is fixedly connected to one end of the limiting post.

[0010] Preferably, an annular stop block is fixedly connected to the other end of the limiting post, one side surface of the pressing block is fixedly connected to one end of the movable rod, and an arc-shaped locking block arranged in an annular array is fixedly connected to the outer surface of the front protective cover.

[0011] Preferably, a limiting hole is formed on one side surface of the arc-shaped locking block, and a stroke groove is formed at one end of the arc-shaped locking block. One end of the stroke groove communicates with the interior of the limiting hole, and the inner wall of the limiting hole is slidably inserted into the outer surface of the limiting post.

[0012] Preferably, the annular barrier is movably sleeved inside one side of the front protective cover, and the two limiting sliders are symmetrically distributed and fixed outside the annular barrier. The limiting sliders are slidably connected in the limiting groove opened inside the front protective cover.

[0013] Preferably, one end of the screw is fixedly connected to one side surface of the annular barrier plate, and the other end of the screw passes through one side of the front protective cover and is threadedly connected to the inner wall of the threaded rotating block, with one end of the threaded rotating block contacting one side of the front protective cover.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In this utility model, the convenient disassembly mechanism facilitates the installation and disassembly of the front and rear protective covers, avoiding the need for specialized tools in traditional operations, simplifying the disassembly and assembly process, and making it easy to operate. Through the cooperation of the staggered protective mechanism, the front protective cover and the annular barrier plate are staggered to provide protection, effectively protecting the front protective cover while increasing the gap and reducing the density. It also facilitates subsequent disassembly and cleaning, reducing the difficulty of cleaning. Attached Figure Description

[0026] Example

[0027] like Figure 1-5 As shown, this utility model provides a technical solution: an electric fan structure that is easy to disassemble and assemble, including a front protective cover 1 and a rear protective cover 2. The opposing surfaces of the front protective cover 1 and the rear protective cover 2 are in contact with each other. The rear protective cover 2 is provided with a convenient disassembly mechanism, which includes an annular mounting block 3, a movable rod 31, a limiting post 32 and a support spring 33. The convenient disassembly mechanism facilitates the disassembly and cleaning of the front protective cover 1 and the rear protective cover 2.

[0028] The front protective cover 1 is equipped with an interleaved protection mechanism, which includes an annular baffle plate 4, a limiting slider 41, a screw 42 and a threaded rotating block 43. The interleaved protection mechanism enables ventilation by interleaving gaps with the front protective cover 1, increasing the gap spacing and reducing the density, which facilitates subsequent cleaning.

[0029] The annular mounting block 3 is fitted onto the outside of the rear protective cover 2. Two movable rods 31 are slidably inserted into the movable holes 34 opened in the annular mounting block 3. The two movable holes 34 are symmetrically distributed on one side surface of the annular mounting block 3. The support spring 33 is fitted onto the outside of the movable rods 31.

[0030] The movable hole 34 guides the movement of the movable rod 31, and the support spring 33, as an elastic component, drives the movable rod 31 to reset and move.

[0031] One end of each of the two support springs 33 is fixedly connected to one side surface of the annular mounting block 3, and the other end of the support spring 33 is fixedly connected to a pressing block 35. The other end of the movable rod 31 is fixedly connected to one end of the limiting post 32.

[0032] The limiting post 32 is provided with a tapered inclined surface near the connection with the movable rod 31. The tapered inclined surface plays a role in smooth transition. The pressing block 35 increases the pressing range of one end of the movable rod 31, making it easier to press.

[0033] The other end of the limiting post 32 is fixedly connected to an annular stop block 36. One side surface of the pressing block 35 is fixedly connected to one end of the movable rod 31. The outer surface of the front protective cover 1 is fixedly connected to an arc-shaped locking block 37 distributed in an annular array. The annular stop block 36 serves to limit and block the arc-shaped locking block 37.

[0034] A limiting hole 38 is provided on one side surface of the arc-shaped locking block 37, and a travel groove 39 is provided at one end of the arc-shaped locking block 37. The travel groove 39 is used to cooperate with the movable rod 31 for rotational connection, so that it transitions into the interior of the limiting hole 38. One end of the travel groove 39 communicates with the interior of the limiting hole 38. The inner wall of the limiting hole 38 is slidably inserted into the outer surface of the limiting post 32. Through the limiting insertion of the limiting post 32 into the limiting hole 38, the arc-shaped locking block 37 is locked and limited.

[0035] The annular baffle plate 4 is movably fitted inside one side of the front protective cover 1. Two limiting sliders 41 are symmetrically distributed and fixed outside the annular baffle plate 4. The limiting sliders 41 are slidably connected in the limiting groove 44 opened inside the front protective cover 1.

[0036] Both the annular baffle plate 4 and the front protective cover 1 are provided with large ventilation gaps. The gaps between the front protective cover 1 and the annular baffle plate 4 are staggered to ensure stable ventilation under relatively safe conditions. In addition, the large gaps facilitate the cleaning of dust adsorbed inside during later disassembly and cleaning, reducing the efficiency of cleaning labor.

[0037] One end of the screw 42 is fixedly connected to one side surface of the annular baffle plate 4, and the other end of the screw 42 passes through one side of the front protective cover 1 and is threadedly connected to the inner wall of the threaded rotating block 43. One end of the threaded rotating block 43 is in contact with one side of the front protective cover 1.

[0038] The screw 42 is threadedly connected and locked to the threaded rotating block 43, which conveniently limits and fixes the annular baffle 4. The threaded connection has high stability, thereby avoiding the problem of vibration and noise caused by the annular baffle 4 loosening during blowing.

[0039] The convenient disassembly mechanism facilitates the installation and disassembly of the front protective cover 1 and the rear protective cover 2, avoiding the need for traditional professional tools, simplifying the disassembly and assembly process, and making it easy to operate. Through the cooperation of the staggered protective mechanism, the front protective cover 1 and the annular barrier plate 4 are staggered to provide protection, effectively protecting the front protective cover 1 while increasing the gap and reducing the density. It also facilitates subsequent disassembly and cleaning, reducing the difficulty of cleaning.

[0040] The working process of this utility model:

[0041] Step 1: During disassembly, press the movable rod 31 with the pressing block 35 to retract its supporting spring 33. The movement of the movable rod 31 causes the limiting post 32 to disengage from the limiting hole 38. At the same time, the movable rod 31 moves into the limiting hole 38. At this time, rotate the front protective cover 1 to make it rotate the arc-shaped locking block 37, which in turn causes the movable rod 31 to move along the stroke groove 39 and disengage from the arc-shaped locking block 37. After disassembling the front protective cover 1, rotate the threaded rotating block 43 counterclockwise to disengage it from the screw 42. Then, the annular barrier plate 4 can be disassembled by the limiting slider 41, which facilitates the separation and cleaning of the front protective cover 1 and the annular barrier plate 4.

[0042] Step two: During installation, the annular barrier plate 4 is guided and installed through the cooperation of the limiting slider 41 and the limiting groove 44, and positioned by the threaded connection between the threaded rotating block 43 and the screw 42. Then, the front protective cover 1 is rotated and connected to the limiting post 32 through the stroke groove 39 on the arc-shaped locking block 37. Since the connection between the limiting post 32 and the movable rod 31 is a conical inclined surface, after the stroke groove 39 presses against its conical inclined surface, the supporting spring 33 contracts, thereby causing the movable rod 31 to move and slide with the stroke groove 39. When it rotates to the limiting hole 38, the elastic force of the supporting spring 33 drives the limiting post 32 to insert into the limiting hole 38 to complete the positioning and installation of the front protective cover 1.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
