Description

Technical Field

[0001] This invention relates to a cleaning device, and more particularly to a cleaning component, a cleaning method, and a fan. Background Technology

[0002] Air flows into the fan through the air inlet, accelerates as the fan blades rotate, and then flows out through the air outlet. During this airflow, pollutants such as dust and pet hair enter the fan's interior with the airflow. Most of these pollutants adhere to the surfaces of the fan's components, affecting the fan's performance to varying degrees.

[0003] To reduce contaminant buildup, a filter can be added to the rear of the fan. Airflow enters the fan through the inlet grille, passes through the filter to remove contaminants, and then flows to the fan blades and outlet grille. The filter needs to be cleaned regularly; otherwise, fan performance will decrease due to contaminant accumulation.

[0004] To achieve timely filter cleaning, Chinese patent document CN119802019A describes the following technical solution: A sensor monitors the filter's clogging status; when clogging is severe, a motor drives a cleaning brush to rotate around the filter's center to clean it. However, this patent document does not describe the structure of the cleaning brush. If a common cleaning brush consisting only of a handle and bristles is used, even after the fan blades have stopped rotating, a large amount of contaminants will fall during the cleaning process, polluting the floor and other areas of the fan. Summary of the Invention

[0005] The technical problem to be solved by this invention is that during the cleaning of the fan filter, a large amount of pollutants fall and contaminate the ground and other areas of the fan.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A cleaning component includes a first power source and a lint scraping device. The lint scraping device includes a lint storage box and a lint scraping roller. The lint storage box has an open box-shaped structure. The lint scraping roller is disposed in the lint storage box and rotatably connected to the lint storage box. A lint scraping felt is provided on the outer side of the lint scraping roller, and a lint collecting felt is provided on the inner side of the lint storage box. When the lint scraping roller rotates relative to the lint storage box, the lint scraping felt moves relative to the lint collecting felt, causing the lint collecting felt to scrape off contaminants on the lint scraping felt into the lint scraping device. The first power source is connected to the lint storage box and is used to rotate the lint scraping device.

[0007] A cleaning method, when performed, enables a cleaning component to clean a target object. The cleaning component includes a first power source and a shaving device. The shaving device includes a lint storage box and a shaving roller. A shaving felt is provided on the outer side of the shaving roller, and a lint collecting felt is provided on the inner side of the lint storage box. When the shaving roller rotates relative to the lint storage box, the shaving felt moves relative to the lint collecting felt, causing the lint collecting felt to scrape contaminants on the shaving felt into the shaving device. The first power source is connected to the lint storage box and is used to rotate the shaving device. The shaving felt includes a left shaving felt and a right shaving felt arranged side by side along the circumference of the shaving roller, and the lint collecting felt includes a left lint collecting felt corresponding to the left shaving felt and a right lint collecting felt corresponding to the right shaving felt. The cleaning method includes: performing steps S1 and S2 sequentially, N times; Step S1: The first power source causes the shaving device to rotate in the forward direction. ; Step S2: The first power source causes the shaving device to rotate in the opposite direction. ; in, , , The radius of the shaving roller is [missing information]. The radius of the target object is... The range of arcs in which the shaving roller rotates relative to the hair storage box. .

[0008] A fan includes an air inlet mesh, an air inlet filter, and a cleaning component provided by the present invention, wherein a shaving device is located between the air inlet mesh and the air inlet filter for cleaning the air inlet filter.

[0009] The beneficial effects of this invention are as follows: The cleaning component provided by the present invention includes a lint collection felt and a lint storage box. The lint collection felt scrapes the contaminants on the lint scraping felt into the lint scraping device, which can significantly reduce the contaminants that fall into the air during the cleaning process of the cleaning component.

[0010] The cleaning method provided by this invention allows the shaving roller to move relative to the target object while remaining stationary relative to the lint storage box, thereby carrying up more contaminants. When the shaving device rotates in the opposite direction, the contaminants on the shaving felt are scraped off by the lint collection felt and placed into the shaving device, thus improving the cleaning effect.

[0011] The fan provided by this invention includes a cleaning component provided by this invention. When cleaning the air intake filter, the cleaning component can collect the scraped-off pollutants, effectively reducing the amount of pollutants falling. Attached Figure Description

[0014] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0015] Fans with air intake filters near the air intake screen are already on the market. These filters effectively block hair, dust, and other contaminants, preventing them from accumulating on the fan motor and blades and affecting fan performance. However, the current method for cleaning air intake filters is mainly manual brushing after removal. As for the method described in Chinese patent document CN119802019A, which uses a cleaning brush and sensor to control the cleaning brush to rotate and clean when the air intake filter is clogged, there is currently a lack of a suitable cleaning brush that can prevent a large amount of contaminants from falling and polluting the ground and other areas of the fan while cleaning.

[0016] This invention provides a cleaning component, please refer to... Figure 1 and Figure 2 The cleaning assembly includes a first power source 3 and a shaving device 1. Please refer to [reference needed]. Figure 2 and Figure 3 The shaving device 1 includes a lint storage box 11 and a shaving roller 12. The lint storage box 11 has an open box-shaped structure, and the shaving roller 12 is disposed in the lint storage box 11 and rotatably connected to the lint storage box 11; please refer to Figure 5 and Figure 6 The outer side of the scraping roller 12 is provided with a scraping felt 121, and the inner side of the hair storage box 11 is provided with a hair collecting felt 111. When the scraping roller 12 rotates relative to the hair storage box 11, the scraping felt 121 moves relative to the hair collecting felt 111, so that the hair collecting felt 111 scrapes the contaminants on the scraping felt 121 into the scraping device 1. The first power source 3 is connected to the hair storage box 11 and is used to make the scraping device 1 rotate.

[0017] Both the scraping felt 121 and the collecting felt 111 are felt sheets with small, dense protrusions on one side. The protrusions can be barbs or other structures. The felt sheets can be purchased commercially, and there are precedents in the prior art for using such felt sheets to clean dust and hair.

[0018] As can be seen from the above description, by scraping the contaminants on the scraping felt 121 into the scraping device 1 through the collecting felt 111, the amount of contaminants falling off during the cleaning process of the cleaning components can be significantly reduced.

[0019] In some embodiments, please refer to Figures 5 to 7The scraping felt 121 includes a left scraping felt 121a and a right scraping felt 121b arranged side by side along the circumference of the scraping roller 12. The collecting felt 111 includes a left collecting felt 111a corresponding to the left scraping felt 121a and a right collecting felt 111b corresponding to the right scraping felt 121b. Both the scraping felt 121 and the collecting felt 111 have barbs. The left scraping felt 121a and the left collecting felt 111a are kept in contact by the barbs, and the right scraping felt 121b and the right collecting felt 111b are kept in contact by the barbs. The barbs of the left scraping felt 121a and the right scraping felt 121b are arranged opposite to each other. The barbs of the left scraping felt 121a and the left collecting felt 111a are arranged opposite to each other.

[0020] As can be seen from the above description, when the shaving device 1 moves to the left, the left shaving felt 121a contacts the target object, and when the shaving device 1 moves to the right, the right shaving felt 121b contacts the target object. The barbs of the left shaving felt 121a and the right shaving felt 121b are set opposite to each other, which is conducive to the left shaving felt 121a and the right shaving felt 121b hooking up the hair on the target object. When the shaving device 1 moves to the right, the contact between the left shaving felt 121a and the left collecting felt 111a decreases. When the shaving device 1 moves to the left, the contact between the right shaving felt 121b and the right collecting felt 111b decreases. The barbs of the left shaving felt 121a and the left collecting felt 111a are positioned opposite each other, and the barbs of the right shaving felt 121b and the right collecting felt 111b are positioned opposite each other. This helps to prevent the left shaving felt 121a and the right shaving felt 121b from carrying hair out of the shaving device 1.

[0021] When the scraping device 1 needs to rotate in both directions, a more suitable design is one where the scraping felt 121 includes a left scraping felt 121a and a right scraping felt 121b arranged side by side along the circumference of the scraping roller 12, and the collecting felt 111 includes a left collecting felt 111a corresponding to the left scraping felt 121a and a right collecting felt 111b corresponding to the right scraping felt 121b. When the scraping device 1 only needs to rotate in the forward direction, only one type of scraping felt 121 and one type of collecting felt 111 are required.

[0022] In some embodiments, please refer to Figure 3 and Figure 8 The wool storage box 11 has a first limiting part 112, and the shaving roller 12 has a second limiting part 122 corresponding to the first limiting part 112. The first limiting part 112 and the second limiting part 122 cooperate to limit the arc range of rotation of the shaving roller 12 relative to the wool storage box 11. , .

[0023] As can be seen from the above description, by setting the first limiting part 112 and the second limiting part 122, the shaving roller 12 can move relative to the target object while it is stationary relative to the hair storage box 11, bringing up more contaminants. When the shaving device 1 rotates in the opposite direction, the contaminants on the shaving felt 121 are scraped off by the collecting felt 111 and into the shaving device 1, thus improving the cleaning effect.

[0024] The method of setting the first limiting part 112 and the second limiting part 122 is easy to implement. As needed, those skilled in the art can achieve the same effect by setting a locking mechanism or other methods.

[0025] In some embodiments, please refer to Figure 2 The scraping roller 12 is also an open box-shaped structure, and the internal space of the hair storage box 11 is connected with the internal space of the scraping roller 12 to form the hair storage space 13.

[0026] As can be seen from the above description, designing the shaving roller 12 as an open box structure can make the hair storage space 13 larger, and the shaving device 1 can hold more contaminants.

[0027] The shaving roller 12 can also be designed as a solid or other shapes, depending on the need.

[0028] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 5 The hair storage space 13 is provided with a hair pressing plate 14. The hair pressing plate 14 can move relative to the hair storage box 11 and the hair scraping roller 12 along the axial direction of the hair scraping roller 12. The hair pressing plate 14 is used to collect the hair in the hair storage space 13. The hair storage box 11 has a detachable upper cover 113. After the upper cover 113 is removed, the hair storage space 13 is connected to the outside of the hair scraping device 1.

[0029] As can be seen from the above description, after removing the top cover 113, the pressing plate 14 can be manipulated to slide along the axial direction of the scraping roller 12 to gather the hair in the hair storage space 13 for removal.

[0030] In some embodiments, please refer to Figure 3 and Figure 4 The shaving device 1 also includes a spring 15, which is compressed between the shaving roller 12 and the hair storage box 11.

[0031] As can be seen from the above description, the spring 15 placed between the scraping roller 12 and the hair storage box 11 can make the scraping roller 12 fit tightly against the target object, which is beneficial for scraping off the contaminants on the target object.

[0032] In some embodiments, please refer to Figures 1 to 4The cleaning assembly also includes a dust collection box 2, which is also an open box structure and is positioned opposite to the hair storage box 11. The dust collection box 2 includes an air outlet filter 21 through which airflow can pass. The first power source 3 is connected to the dust collection box 2 and is used to make the hair removal device 1 and the dust collection box 2 rotate synchronously.

[0033] The present invention also provides a cleaning method, which, when executed, enables the cleaning components of some embodiments of the present invention to clean a target object. In some embodiments of the present invention, the cleaning components provided by the present invention include a first power source 3 and a shaving device 1. The shaving device 1 includes a lint storage box 11 and a shaving roller 12. A shaving felt 121 is provided on the outer side of the shaving roller 12, and a lint collecting felt 111 is provided on the inner side of the lint storage box 11. When the shaving roller 12 rotates relative to the lint storage box 11, the shaving felt 121 moves relative to the lint collecting felt 111, causing the lint collecting felt 111 to scrape the contaminants on the shaving felt 121 into the shaving device 1. The first power source 3 is connected to the lint storage box 11 and is used to rotate the shaving device 1. The scraping felt 121 includes a left scraping felt 121a and a right scraping felt 121b arranged side by side along the circumference of the scraping roller 12, and the collecting felt 111 includes a left collecting felt 111a corresponding to the left scraping felt 121a and a right collecting felt 111b corresponding to the right scraping felt 121b.

[0034] The cleaning method includes: performing steps S1 and S2 sequentially, N times; Step S1: The first power source 3 causes the shaving device 1 to rotate in the forward direction. ; Step S2: The first power source 3 causes the shaving device 1 to rotate in the opposite direction. ; in, , , The radius of the shaving roller 12, The radius of the target object, The range of arcs in which the shaving roller 12 rotates relative to the hair storage box 11. .

[0035] As can be seen from the above description, the arc range of the shaving roller 12 relative to the lint storage box 11 is reasonably set to allow the shaving device 1 to rotate in both the forward and reverse directions. This allows the shaving roller 12 to move relative to the target object while remaining stationary relative to the lint storage box 11, thus carrying up more contaminants. When the shaving device 1 rotates in the reverse direction, the contaminants on the shaving felt 121 are scraped off by the lint collection felt 111 and placed into the shaving device 1, thereby improving the cleaning effect.

[0036] The present invention also provides a fan, please refer to Figure 1 and Figure 2The fan includes an air inlet mesh 5, an air inlet filter 4, and a cleaning component provided by the present invention. A shaving device 1 is located between the air inlet mesh 5 and the air inlet filter 4 and is used to clean the air inlet filter 4.

[0037] As can be seen from the above description, applying the cleaning component provided by the present invention to a fan can solve the cleaning problem of the air intake filter 4. During the cleaning process, the scraping felt 121 and the collecting felt 111 work together to collect the pollutants scraped off the air intake filter 4 by the scraping felt 121 into the scraping device 1, thus preventing a large amount of pollutants from falling and contaminating the ground and other areas of the fan.

[0038] In some embodiments, please refer to Figures 2 to 4 The cleaning assembly includes a dust collection box 2 and a bracket 9 for fixing a first power source 3. The dust collection box 2 is an open box-shaped structure and is arranged opposite to the hair collection box 11. The dust collection box 2 includes an exhaust filter 21 through which airflow can pass. The first power source 3 is connected to the dust collection box 2 and is used to make the hair removal device 1 and the dust collection box 2 rotate synchronously. The dust collection box 2 is located between the inlet filter 4 and the bracket 9. There is a gap between the dust collection box 2 and the inlet filter 4. When the fan blade 7 rotates, the airflow flows sequentially through the inlet filter 4, the gap, the internal space of the dust collection box 2, and the exhaust filter 21.

[0039] As described above, the dust collection box 2 is located between the inlet filter 4 and the bracket 9, and will not interfere with the fan blades 7. There is a gap between the dust collection box 2 and the inlet filter 4, allowing the dust scraped off from the inlet filter 4 to enter the dust collection box 2 with the airflow and be blocked by the outlet filter 21. Therefore, even if the cleaning component is activated when the fan blades 7 are rotating, it will not significantly affect the cleanliness of the airflow generated by the fan.

[0040] If necessary, the ash collection box 2 may not be required.

[0041] Please refer to Figures 1 to 9 One embodiment of the present invention is as follows: A type of fan, please refer to Figure 1 and Figure 2 The fan includes an air inlet screen 5, a scraping device 1, an air inlet filter 4, a dust collection box 2, a bracket 9, fan blades 7, and an air outlet screen 6 arranged in sequence. The bracket 9 is equipped with a first power source 3 for synchronizing the rotation of the scraping device 1 and the dust collection box 2, and a second power source 8 for rotating the fan blades 7. Both the first power source 3 and the second power source 8 are motors, and the first power source 3 and the second power source 8 are arranged opposite to each other.

[0042] The cleaning assembly includes a first power source 3, a dust collection box 2, and a lint scraping device 1. The dust collection box 2 is an open box-shaped structure, positioned opposite the lint storage box 11. The dust collection box 2 includes an outlet filter 21 through which airflow can pass. There is a gap between the dust collection box 2 and the inlet filter 4. When the fan blade 7 rotates, the airflow sequentially flows through the inlet filter 4, the gap, the internal space of the dust collection box 2, and the outlet filter 21.

After removing the top cover 113, the hair storage space 13 is connected to the outside of the hair scraping device 1.

[0044] Please refer to Figure 3 and Figure 4 The shaving device 1 also includes a spring 15, which is compressed between the shaving roller 12 and the hair storage box 11. The shaft portion 123 of the shaving roller 12 is limited by the hole on the hair storage box 11 and has only a small range of motion. The spring 15 presses the shaft portion 123 through the pressure block 16, so that the shaving roller 12 maintains a tendency to move away from the hair storage box 11.

[0045] The first power source 3 is fixedly connected to the ash collection box 2 and the hair removal device 1 respectively. The hair storage box 11 includes two parts connected by the first pin 17, and the ash collection box 2 includes two parts connected by the second pin 22, so as to facilitate the disassembly and cleaning of the ash collection box 2 and the hair removal device 1.

[0046] The shaving device 1 also includes a guide part 114, which is guided by the inner annular track of the fan to achieve stable rotation of the shaving device 1.

[0047] Please refer to Figure 5 and Figure 6 The outer side of the scraping roller 12 is provided with a scraping felt 121, and the inner side of the hair storage box 11 is provided with a hair collecting felt 111. When the scraping roller 12 rotates relative to the hair storage box 11, the scraping felt 121 moves relative to the hair collecting felt 111, so that the hair collecting felt 111 scrapes the contaminants on the scraping felt 121 into the scraping device 1.
