Description

A new type of duct ventilation fan

Technical Field

The utility model relates to the technical field of ventilation fans, and in particular to a novel pipeline ventilation fan.

Background Art

Ducted ventilation fans are a type of ventilation fan, which is an air conditioning appliance that uses an electric motor to drive the rotation of the fan blades to drive the air flow, so that the indoor and outdoor air are exchanged. Also known as ducted fans or ducted fans, the purpose of ventilation is to remove the dirty air in the room and adjust the temperature, humidity and sensory effect. Ducted ventilation fans are widely used in homes and public places, and the driving motors of ducted ventilation fans currently on the market usually occupy a large part of the ventilation duct space, resulting in a decrease in the amount of air circulation. In addition, because the motor is placed in the duct, the particles mixed in the flowing wind can easily adhere to the motor, thereby affecting the heat dissipation of the motor, and the fan blades are also easily contaminated with particles or dust, so that the effect of the fan blades driving the air flow is not ideal.

Chinese patent number CN207454350U provides a duct ventilation fan, including a box body, a wind wheel and a hanging bracket group; the two sides of the box body are respectively provided with a main vent and a side vent, and the wind wheel is rotatably arranged at the main vent; the hanging bracket group includes a main hanging bracket and a secondary hanging bracket, the main hanging bracket and the side vent of the box body are arranged on the opposite sides of the box body, and the secondary hanging bracket is slidably sleeved on the main hanging bracket. The duct ventilation fan of the utility model meets the installation requirements of keels of different widths by setting a hanging bracket group, and slidingly sleeves the secondary hanging bracket on the main hanging bracket, which is convenient for installation and disassembly, and expands the installation and use range of the duct ventilation fan.

At present, although the existing new duct ventilation fans are easy to install and disassemble, their driving motors occupy a large space inside the ventilation duct, resulting in a decrease in wind flow. In addition, when the fan blades are used for a long time, particles such as oil or dust will adhere to them, which will cause the fan blades to drive the air flow to achieve less than ideal effect.

Example

Please refer to FIGS. 1-4 . The utility model provides a technical solution: a novel duct ventilation fan, comprising a driving structure 100 and a mounting structure 200 .

Please refer to Figure 1-2. The driving structure 100 includes a shell 110 and a moving part 120. A slide groove 124 is also opened at the bottom of the shell 110. The moving part 120 is fixed to one side of the shell 110. A protective net 111 is fixed inside the shell 110. The protective net 111 can prevent foreign objects from touching the rotating fan blades 116. A support frame 112 is fixed inside the shell 110. The support frame 112 supports the fan blades 116 and protects the helical teeth 1 14 and the helical teeth 2 115. A first motor 113 is fixed to one side of the shell 110. The output shaft end of the first motor 113 is fixed with the helical teeth 1 14. The helical teeth 1 14 are meshed with the helical teeth 2 115 on one side. The fan blades 116 are fixed inside the helical teeth 2 115. The fan blades 116 are fixed inside the helical teeth 2 115 through an axis. The fan blades 116 are rotatably connected to one side of the support frame 112.

The moving part 120 includes a protective shell 121, which is fixed on one side of the outer shell 110. A second motor 122 is fixed inside the protective shell 121. A gear 123 is fixed to the output shaft end of the second motor 122. The gear 123 is meshed with the rack 212. A slide groove 124 is provided at the bottom of the protective shell 121. A limit strip 125 is fixed on one side of the slide groove 124. The limit strip 125 can prevent the support strip 211 from being pulled out of the slide groove 124.

Please refer to FIG. 1 and FIG. 3 - 4 , the mounting structure 200 includes a supporting member 210 and a dust removing member 220 . The supporting member 210 is slidably connected to the inside of the moving member 120 , and the dust removing member 220 is slidably connected to the inside of the housing 110 .

The support member 210 includes a support bar 211, which is slidably connected to the inside of the slide groove 124. A rack 212 is fixed to the top of the support bar 211, and the rack 212 is meshed with the gear 123. A positioning rod 213 is threadedly connected to the inside of the support bar 211. The positioning rod 213 pushes the slide bar 215 so that the slide bar 215 and the support bar 211 cannot slide. A rotating handle 214 is fixed to the end of the positioning rod 213. In order to facilitate the rotation of the positioning rod 213, the rotating handle 214 is slidably connected to the inside of the support bar 211. A fixing plate 216 is fixed to the end of the slide bar 215, and a fixing hole 216 is opened on one side of the fixing plate 216. 7. The screws can fix the fixing plate 216 in a suitable position through the fixing holes 217. The dust removal member 220 includes a slider 221. The slider 221 serves to limit the moving direction. The slider 221 is slidably connected to the inside of the housing 110. A push handle 222 is fixed to one side of the slider 221. The push handle 222 is convenient for pushing the slider 221 from the outside of the device, thereby indirectly pushing the fixing frame 223 to move. A fixing frame 223 is fixed to the other side of the slider 221. An upper brush 224 is fixed inside the fixing frame 223. A lower brush 225 is fixed inside the fixing frame 223. The upper brush 224 and the lower brush 225 are soft so that they can be bent.

Specifically, the working principle of the new duct ventilation fan is as follows: when in use, first fix the fixing plate 216 to the wall through the fixing hole 217, then slide the support bar 211 to make the distances of the protruding slide bars 215 at both ends of the support bar 211 consistent, and then rotate the handle 214 to make the positioning rod 213 press against the slide bar 215 under the action of the threaded connection, so that the slide bar 215 and the support bar 211 cannot slide, thereby fixing the device, and then start the first motor 113, and drive the bevel gear 1 14 to rotate through the first motor 113, so that the bevel gear 2 115 can drive the fan blade 116 to rotate, and at this time, under the rotation of the fan blade 116, the air will be moved. Rapid flow, thereby achieving the effect of replacing indoor air. If the housing 110 needs to be moved, the second motor 122 is started, so that the gear 123 is engaged with the rack 212, and the housing 110 can be driven to move through the protective shell 121, so that the housing 110 can be moved to a suitable position for ventilation. After long-term use, oil or dust particles will adhere to the fan blades 116. At this time, it is only necessary to push the slider 221 to move through the push handle 222, so that the fixing frame 223 can be placed on the rotation trajectory of the fan blades 116, so as to utilize the friction between the fan blades 116 and the upper brush 224 and the lower brush 225 when the fan blades 116 rotate to achieve the purpose of removing stains on the fan blades 116.

It should be noted that the specific models and specifications of the first motor 113 and the second motor 122 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

The power supply and principle of the first motor 113 and the second motor 122 are clear to those skilled in the art and will not be described in detail herein.

The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
