Description

Technical Field

[0001] The utility model belongs to the technical field of fan devices, relates to a fan, and particularly relates to a novel fan. Background Technique

[0002] After the existing fan works for a long time, dust and impurities will adhere to the blades and need to be cleaned. The blades are generally arranged inside the fan housing, and the cleaning is relatively troublesome. In particular, it is very difficult to clean the dust and impurities on the back of the blades or on the surface of the shaft inside the housing. The wind blown out with dust and impurities pollutes the environment and affects the use. Summary of the Invention

[0003] The purpose of the utility model is to provide a novel fan that is convenient to maintain and improves the use effect in view of the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A novel fan, including a housing and blades arranged inside the housing, characterized in that a flat layer groove is opened in the inner circle of the housing, a fixing plate is installed in the flat layer groove, a guiding plate that moves back and forth along its top is arranged on the fixing plate, the guiding plate is located below the blades, and a vertical plate for installing the blades is fixed on the top of the guiding plate. A shaft hole is opened on the vertical plate, and a transmission shaft for installing the blades is fitted in the shaft hole. A driving motor is connected inside the housing behind the transmission shaft, and the rear end of the fixing plate has a rear plate extending vertically upward. The guiding plate and the rear plate are fixedly connected by a long screw.

[0005] In the above-mentioned novel fan, a linear guide rail is arranged between the guiding plate and the fixing plate.

[0006] In the above-mentioned novel fan, a handle is arranged at the top of the guiding plate and in front of the blades.

[0007] In the above-mentioned novel fan, the outer end of the blade has a turned-up and extended guiding part.

[0008] In the above-mentioned novel fan, the top of the housing has a base.

[0009] Compared with the prior art, the novel fan has the advantage of being convenient for cleaning and maintaining the internal structure. Brief Description of the Drawings

[0010] Figure 1 is the three-dimensional view of the novel fan.

[0011] Figure 2 is Figure 1 the partial sectional view of A-A in

[0012] In the figure, 1 is the casing; 2 is the fan blade; 3 is the fixing plate; 4 is the guiding plate; 5 is the vertical plate; 6 is the transmission shaft; 7 is the rear plate; 8 is the linear guide rail; 9 is the handle; 10 is the flow guiding part; 11 is the base. Detailed implementation mode

[0013] The following are specific embodiments of the present utility model and in combination with the attached drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.

[0014] As Figure 1 、 Figure 2 shown, this new type of fan includes a casing 1 and a fan blade 2 arranged inside the casing 1. A flat layer groove is opened in the inner circle of the casing 1, and a fixing plate 3 is installed in the flat layer groove. A guiding plate 4 that moves back and forth along the top of the fixing plate 3 is provided on the fixing plate 3. The guiding plate 4 is located below the fan blade 2, and a vertical plate 5 for installing the fan blade 2 is fixed to the top of the guiding plate 4. A shaft hole is opened on the vertical plate 5, and a transmission shaft 6 for installing the fan blade 2 is fitted in the shaft hole. A driving motor is connected behind the transmission shaft 6 and inside the casing 1. The rear end of the fixing plate 3 has a rear plate 7 extending vertically upward. The guiding plate 4 and the rear plate 7 are fixedly connected by long rod screws. When cleaning the fan blade 2 and the transmission shaft 6, the guiding plate 4 is moved out, and the fan and the transmission shaft 6 on the guiding plate 4 are pulled out, thus facilitating cleaning. The guiding plate 4 and the rear plate 7 are connected, that is, the guiding plate 4 can be locked on the fixing plate 3.

[0015] Preferably, a linear guide rail 8 is provided between the guiding plate 4 and the fixing plate 3.

[0016] Preferably, a handle 9 is provided at the top of the guiding plate 4 and in front of the fan blade 2.

[0017] Furthermore, the outer end of the fan blade 2 has a flow guiding part 10 that folds and extends, improving the wind gathering ability.

[0018] Preferably, the top of the casing 1 has a base 11.

[0019] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model belongs can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.

[0020] Although terms such as housing 1, fan blade 2, fixing plate 3, guiding plate 4, vertical plate 5, transmission shaft 6, rear plate 7, linear guide 8, handle 9, flow guiding part 10, base 11 are used more frequently in this text, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the present utility model; any interpretation of them as an additional limitation is contrary to the spirit of the present utility model.
