Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a portable self-cleaning handheld fan. Background Technology

[0002] In recent years, the intense heat has led to the popularity of various battery-powered, portable, and lightweight handheld fans. These fans are especially important for users who frequently need to go out or spend time outdoors. However, as fans generate airflow, they also draw dust from the air into the fan. After prolonged use, a large amount of dust accumulates on the fan blades. If the dust is not cleaned in time, bacteria will grow, polluting the air and potentially causing respiratory infections. Current cleaning methods typically involve removing the protective mesh to wipe and clean the fan blades, or using a cotton swab dipped in water to wipe and clean the blades inside the protective mesh. However, these cleaning methods are cumbersome, time-consuming, and laborious, resulting in a poor user experience. Utility Model Content

[0003] The purpose of this invention is to provide a portable self-cleaning handheld fan, which aims to at least solve the problem of dust accumulation on the blades of existing handheld fans, making them difficult to clean.

[0004] To achieve the above objectives, the present invention provides a portable self-cleaning handheld fan, comprising:

[0005] A fan handle, one end of which is provided with a fan compartment;

[0006] A fan blade assembly, which is installed in the fan housing;

[0007] A cleaning component is movably connected to the fan handle so that the cleaning component can be moved to a cleaning state or retracted to a storage state. In the cleaning state, the cleaning component can extend at least partially into the fan compartment to clean at least a portion of the fan blade assembly. In the storage state, the cleaning component can be housed within the fan handle.

[0008] Furthermore, the fan handle is provided with a receiving cavity, which is connected to the fan housing through a first opening. The cleaning component can extend at least partially into the fan housing through the first opening to clean at least part of the fan blade assembly.

[0009] Furthermore, the receiving cavity is arranged vertically so that the cleaning assembly can slide vertically along the receiving cavity.

[0010] Furthermore, the cleaning component includes:

[0011] A brush, which is slidably mounted on the fan handle;

[0012] A driving component is connected to the brush drive to drive and control the sliding of the brush.

[0013] Furthermore, the driving component is a handheld protrusion.

[0014] Furthermore, the brush includes:

[0015] Structural panels;

[0016] Multiple bristles, one end of which is mounted on the structural plate, and the other end of which extends toward the fan compartment to form a columnar scraping area.

[0017] Furthermore, it also includes a positioning structure, which is disposed between the fan handle and the cleaning component, so that the cleaning component can be positioned in a cleaning state or a storage state.

[0018] Furthermore, the positioning structure includes a first positioning groove and a second positioning groove spaced apart on the fan handle, and the cleaning component is provided with an elastic protrusion, so that when the elastic protrusion is engaged in the first positioning groove, the cleaning component can be positioned in a cleaning state, and when the elastic protrusion is engaged in the second positioning groove, the cleaning component can be positioned in a storage state.

[0019] Furthermore, a sliding track is provided between the first positioning groove and the second positioning groove to guide the sliding of the elastic protrusion.

[0020] Furthermore, the fan handle includes a control component, the fan blade assembly includes a motor, and the control component is electrically connected to the motor so that the motor can be controlled to rotate forward or backward, so that the cleaning component can clean the fan blade assembly from different angles.

[0021] As can be seen from the above technical solution, the portable self-cleaning handheld fan of this utility model achieves a self-cleaning effect by setting a movable cleaning component. Specifically, the cleaning component can move relative to the fan handle to a cleaning state and a retracted state. In the cleaning state, the cleaning component can extend at least partially into the fan compartment. At this time, the fan blade assembly is activated to make the fan blades rotate, and multiple fan blades can continuously pass through the cleaning component, so that the cleaning component can scrape the dust on the fan blades to achieve the effect of cleaning the dust on the fan blades. In the retracted state, the cleaning component can be housed in the fan handle to avoid the cleaning component affecting the normal operation of the fan blade assembly and the fan. With this setting, the user does not need to remove the protective net or wipe with cotton swabs to complete the cleaning work, avoiding the accumulation of dust on the fan blades, which would cause poor air quality and lead to respiratory infections. The air is clean and the usage effect is good.

[0040] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this application. Wherein, as shown in the accompanying drawings… Figure 1 The handheld fan shown is vertically oriented.

[0041] Please refer to the following: Figures 1 to 10This embodiment provides a portable self-cleaning handheld fan, including a fan handle 100, a fan blade assembly 200, and a cleaning component 300. One end of the fan handle 100 is provided with a fan compartment 110, and the fan blade assembly 200 is installed in the fan compartment 110. The cleaning component 300 is movably connected to the fan handle 100 so that the cleaning component 300 can move to a cleaning state or be retracted to a storage state. In the cleaning state, the cleaning component 300 can extend at least partially into the fan compartment 110 to clean at least part of the fan blade assembly 200. In the storage state, the cleaning component 300 can be housed in the fan handle 100.

[0042] As can be seen, the portable self-cleaning handheld fan of this embodiment enables the fan to achieve a self-cleaning effect by setting a movable cleaning component 300. Specifically, the cleaning component 300 can move relative to the fan handle 100 to a cleaning state and a retracted state. In the cleaning state, the cleaning component 300 can extend at least partially into the fan compartment 110. At this time, the fan blade assembly 200 is activated to make the fan blades rotate. Multiple fan blades can continuously pass through the cleaning component 300 so that the cleaning component 300 can scrape the dust on the fan blades to achieve the effect of cleaning the dust on the fan blades. In the retracted state, the cleaning component 300 can be housed in the fan handle 100 to avoid the cleaning component 300 affecting the normal operation of the fan blade assembly 200 and the fan. With this setting, the user can complete the cleaning work without removing the protective net or wiping with cotton swabs, avoiding the accumulation of dust on the fan blades, which would cause poor air quality and lead to respiratory infections. The air is clean and the usage effect is good.

[0043] It should be noted that the dust on the fan blades 220 is not evenly adhered to the blades. Instead, due to the centrifugal force generated by the high-speed rotation of the fan, most of the dust accumulates on the edges of the blades 220. The cleaning component 300 can at least scrape the edges of the blades 220 to clean the dust from the fan blades. This prevents the dust on the fan blades 220 from being blown towards the user when the fan is rotating at high speed, thus improving the airflow quality and preventing the user from inhaling dust and causing respiratory infections.

[0044] Furthermore, such as Figures 1 to 4 As shown, the fan handle 100 is provided with a receiving cavity 120, which is connected to the fan housing 110 through a first opening 160. The cleaning component 300 can extend at least partially into the fan housing 110 through the first opening 160 to clean at least part of the fan blade assembly 200.

[0045] Among them, such as Figures 1 to 8As shown, the accommodating cavity 120 provides storage space for the cleaning component 300. By integrating the accommodating cavity 120 into the fan handle 100, the cleaning component 300 can be hidden inside the fan handle 100. This design helps to reduce the size of the fan, make it easier to hold, and improve the portability of the handheld fan. Furthermore, the cavity wall of the accommodating cavity 120 can separate the cleaning component from the rest of the internal structure of the fan handle 100 to prevent damage caused by friction between the cleaning component 300 and the circuit components when it slides.

[0046] Furthermore, such as Figures 1 to 8 As shown, the accommodating cavity 120 is arranged vertically so that the cleaning component 300 can slide vertically along the accommodating cavity 120. This arrangement makes full use of the longitudinal length of the fan handle 100, which can accommodate a larger cleaning component 300. This not only increases the cleaning coverage area, but also does not require additional space in the fan compartment 110 or the external space of the fan handle 100, making the fan compact overall. When the cleaning component 300 extends vertically upward, its bristles 312 can enter the gap between the fan blades vertically or obliquely, which better fits the radial distribution characteristics of the fan blades, increases the cleaning coverage area, and ensures that the cleaning component 300 can accurately align with the fan blade area every time it extends, avoiding incomplete cleaning due to sliding deviation.

[0047] In this embodiment, as Figure 5 and Figure 6 As shown, the cleaning component 300 includes a brush 310 and a drive component 320. The brush 310 is slidably mounted on the fan handle 100, and the drive component 320 is driven to connect with the brush 310 so as to drive and control the brush 310 to slide.

[0048] In this embodiment, the driving component 320 is driven manually, such as... Figures 5 to 9 As shown, the drive component 320 is a handheld protrusion 322.

[0049] The fan handle 100 has a vertically formed sliding groove 130 on its side wall that connects to the interior of the accommodating cavity 120. The handheld protrusion 322 is inserted into the sliding groove 130 and connected to the brush 310.

[0050] In other possible implementations, the drive assembly 320 can be driven by electric, pneumatic or hydraulic means. Preferably, the drive assembly 320 is an electric push rod. The telescopic end of the electric push rod is connected to the brush 310, and the fixed end of the electric push rod is installed in the fan handle 100. The electric push rod is electrically connected to the circuit board of the fan handle 100. The fan handle 100 is provided with a telescopic switch so that the brush 310 can be moved up and down by pressing the telescopic switch.

[0051] Furthermore, such as Figure 5 and Figure 6As shown, the brush 310 includes a structural plate 311 and a plurality of bristles 312. One end of the bristles 312 is mounted on the structural plate 311, and the other end of the bristles 312 extends toward the fan compartment 110 to form a columnar scraping area.

[0052] The structural plate 311 is fixedly connected to the drive assembly 320. The fan blades of the fan blade assembly 200 are radially distributed around the motor shaft. The columnar scraping area can wrap around the fan blades from multiple angles. When the brush 310 extends into the fan compartment 110, the columnar scraping area can simultaneously contact the front, back and root gaps of the fan blades, solving the limitation that the flat bristles 312 can only clean a single surface. Multiple bristles 312 are evenly arranged on the structural plate 311 to form a dense scraping unit, which can not only sweep away surface dust, but also penetrate into the narrow gaps between the fan blades through the elastic deformation of the bristles 312 for deep cleaning. The structural plate 311 can be made of hard plastic, and the bristles 312 can be made of elastic bristles 312.

[0053] In this embodiment, as Figures 1 to 10 As shown, it also includes a positioning structure, which is disposed between the fan handle 100 and the cleaning component 300, so that the cleaning component 300 can be positioned in a cleaning state or a storage state.

[0054] During the cleaning process, the fan blades are rotating, and the user may experience slight shaking when holding the fan. The positioning structure can securely lock the cleaning component 300 in the cleaning state, preventing it from accidentally sliding due to vibration, gravity, or accidental touch. This ensures that the brush 310 always maintains effective contact with the fan blades, guaranteeing the continuity and thoroughness of the cleaning process. The stable positioning allows the user to fix the cleaning component 300 without continuously applying external force. In non-cleaning scenarios, the positioning structure locks the cleaning component 300 in the storage state, preventing it from accidentally extending due to bumps or collisions during transport.

[0055] Furthermore, the positioning structure includes a first positioning groove 140 and a second positioning groove 150 spaced apart on the fan handle 100, and an elastic protrusion 410 is provided on the cleaning component 300 so that when the elastic protrusion 410 is engaged in the first positioning groove 140, the cleaning component 300 can be positioned in the cleaning state, and when the elastic protrusion 410 is engaged in the second positioning groove 150, the cleaning component 300 can be positioned in the storage state.

[0056] Among them, such as Figures 6 to 8As shown, the elastic protrusion 410 has a certain elastic deformation capability. After being inserted into the first positioning groove 140 or the second positioning groove 150, it can fit tightly against the groove wall through its own elasticity. When the user slides the cleaning component 300, the elastic protrusion 410 will create a feeling of locking when it comes out of the first positioning groove 140 and slides into the second positioning groove 150 or from the second positioning groove 150 into the first positioning groove 140. The tactile feedback provides a clear prompt, and the user can complete the operation without visual confirmation, which is especially suitable for one-handed operation scenarios.

[0057] Furthermore, such as Figure 10 As shown, a sliding track 170 is provided between the first positioning groove 140 and the second positioning groove 150 to provide guidance for the sliding of the elastic protrusion 410.

[0058] In this embodiment, as Figures 1 to 9 As shown, the fan handle 100 includes a control component 500, and the fan blade assembly 200 includes a motor 210. The control component 500 is electrically connected to the motor 210 so that the motor 210 can be controlled to rotate forward or backward, so that the cleaning component 300 can clean the fan blade assembly 200 from different angles.

[0059] During long-term use, dust, hair, and other debris can accumulate on different sides, root angles, and even edge gaps of the fan blades due to factors such as the direction of rotation and airflow characteristics. If the motor 210 can only rotate in one direction, the cleaning component 300 may only effectively clean the front side of the fan blades, leaving blind spots on the back side or hidden areas. By controlling the motor 210 to rotate in both directions using the control component 500, different angles and sides of the fan blades can sequentially contact the cleaning component 300, significantly reducing cleaning dead spots and ensuring that all parts of the fan blades are thoroughly cleaned, thus expanding the cleaning coverage area.

[0060] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0061] This utility model discloses a portable self-cleaning handheld fan. By incorporating a movable cleaning component 300, the fan achieves a self-cleaning effect. Specifically, the cleaning component 300 can move relative to the fan handle 100 to a cleaning state and a retracted state. In the cleaning state, the cleaning component 300 extends at least partially into the fan compartment 110. At this time, the fan blade assembly 200 is activated, causing the fan blades to rotate. Multiple fan blades continuously pass through the cleaning component 300, allowing it to scrape away dust from the blades, thus achieving the effect of cleaning the dust. In the retracted state, the cleaning component 300 is housed within the fan handle 100 to prevent it from interfering with the normal operation of the fan blade assembly 200. This design allows users to complete the cleaning process without disassembling the protective net or wiping with cotton swabs, preventing dust accumulation on the fan blades and avoiding poor airflow quality that could lead to respiratory infections. The fan provides clean airflow and excellent performance.
