Description

Technical Field

[0001] This utility model relates to the field of fluid machinery equipment technology, specifically to a fan. Background Technology

[0002] A fan is a machine that uses input mechanical energy to increase gas pressure and discharge gas; it is a type of driven fluid machinery.

[0003] Currently, existing fans typically consist of a casing, inside which a motor is fixedly installed, and an impeller is installed at the motor's output end. Since the casing is open from front to back, when not in use, external dust and impurities can enter the casing and adhere to the impeller. When these impurities mix with water vapor, they form dirt, affecting the operation of the fan. Therefore, it is necessary to clean the dirt on the surface of the impeller. However, since the back of the impeller is located inside the casing, it is difficult to wipe it with a cloth, making the cleaning operation quite difficult. Utility Model Content

[0004] The purpose of this invention is to provide a fan that solves the aforementioned problems.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a fan, including a housing, a motor is installed inside the housing, an impeller is installed on the output end of the motor, a base is slidably connected inside the housing, the motor is fixedly installed inside the base, a sliding groove is formed on the side wall of the housing along the length direction, a sliding strip is provided on the motor, the sliding strip passes through the sliding groove and is connected to an insert, a through groove for the insert to pass through is formed on the housing, a latch is slidably connected on the housing, and a slot for the latch to engage is formed on the insert.

[0006] As a further feature of this invention, a sliding sleeve is provided on the housing, and the latch is slidably connected inside the sliding sleeve.

[0007] As a further feature of this invention, a slide rail is provided on the slide sleeve along its length, and a paddle is provided on the latch that passes through the slide rail.

[0008] As a further feature of this invention, a slide rail is provided on the inner wall of the housing, and a slider is provided on the base that is slidably connected inside the slide rail.

[0009] As a further feature of this invention, a tension spring is connected between the slider and the inner wall of the slide rail, and the tension spring is used to keep the impeller always inside the housing in its natural state.

[0010] As a further feature of this invention, a guide rod is fixedly connected inside the slide rail, and the guide rod passes through the slider and the tension spring.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When the impeller needs cleaning, this invention allows the insert to slide towards the air inlet of the casing, thereby causing the sliding strip to slide along the groove, which in turn moves the motor, causing the impeller to extend out of the casing. Once the impeller is fully extended, the insert will pass through the groove, allowing the latch to be pushed into the slot for fixation, keeping the impeller exposed. This allows the front and back of the impeller to be wiped with a cloth, preventing dirt residue. The cleaning effect is good, and the cleaning operation is convenient and simple.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4As shown, the fan includes a casing 1, a motor 2 is installed inside the casing 1, and an impeller 3 is installed at the output end of the motor 2. A base 4 is slidably connected inside the casing 1, and the motor 2 is fixedly installed inside the base 4. A groove 5 is formed along the length of the side wall of the casing 1, and a sliding strip 6 is provided on the motor 2. The sliding strip 6 passes through the groove 5 and is connected to an insert 7. A through groove 8 is formed on the casing 1 for the insert 7 to pass through. A latch 9 is slidably connected to the casing 1, and a slot 10 is formed on the insert 7 for the latch 9 to engage. When it is necessary to clean the impeller 3, the insert 7 can be pushed to slide towards the air inlet of the casing 1, thereby cleaning the impeller 3. The sliding bar 6 slides along the groove 5, which in turn drives the motor 2 to move, causing the impeller 3 to extend out of the housing 1. When the impeller 3 is fully extended, the insert bar 7 passes through the groove 8, which pushes the latch 9 into the slot 10 for fixation, keeping the impeller 3 exposed. This allows for wiping the front and back of the impeller 3 with a cloth, preventing dirt residue and providing a good cleaning effect. The cleaning operation is also convenient and simple. After cleaning, simply pull the latch 9 out of the slot 10 and push the insert bar 7 to reset. This will drive the motor 2 to reset via the sliding bar 6, allowing the impeller 3 to retract back into the housing 1. The operation is convenient.

[0020] Please see Figure 2-4 As shown, a sliding sleeve 11 is provided on the housing 1, and a latch 9 is slidably connected inside the sliding sleeve 11. The latch 9 can extend or retract inside the sliding sleeve 11, thereby being able to be inserted into or pulled out of the latch 10. The operation is convenient. A slide rail 12 is provided on the sliding sleeve 11 along the length direction, and a paddle 13 is provided on the latch 9 that passes through the slide rail 12. By pushing the paddle 13 to slide along the slide rail 12, the latch 9 can be pushed to extend or retract inside the sliding sleeve 11, making the operation relatively easy and effortless.

[0021] Please see Figure 1-4As shown, a slide rail 14 is provided on the inner wall of the housing 1, and a slider 15 is provided on the base 4, which is slidably connected inside the slide rail 14. When the motor 2 is moved, the base 4 will slide inside the housing 1, thereby causing the slider 15 to slide inside the slide rail 14. By limiting the slider 15 through the slide rail 14, the sliding direction of the base 4 can be limited, making the operation of the motor 2 and the impeller 3 extending or retracting into the housing 1 smoother. A tension spring 16 is connected between the slider 15 and the inner wall of the slide rail 14. The tension spring 16 is used to keep the impeller 3 always in its natural state. Inside the casing 1, after the impeller 3 is pushed out of the casing 1, it will pull the tension spring 16, causing it to stretch and deform. Then, by inserting the latch 9 into the slot 10, it can be fixed. After the latch 9 is pulled out from the slot 10, the tension spring 16 will automatically spring back and return to its original shape due to being freed from restraint, thereby driving the impeller 3 to automatically reset. This can prevent the impeller 3 from slipping out due to accident during normal use of the fan. In addition, a guide rod is fixedly connected inside the slide rail 14. The guide rod passes through the slider 15 and the tension spring 16, thereby guiding the sliding and the extension and retraction of the tension spring 16.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
