DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] For examples, see Figures 1 to 10 The present embodiment provides a fan with an air volume regulating valve function, including a body 1, a valve body 2, an air duct 3, blades 4, a driving device 5, a filter 6 and a sensing component.

[0047] In this embodiment, the air volume regulating valve is the valve body 2 in the present invention. The driving device 5 can open multiple blades 4 to adjust the air volume and wind direction. The driving device 5 can adopt the existing motor to drive the belt and gears, etc., so that the blades 4 rotate synchronously. This is one of the technical means known in the art and will not be repeated here. This method focuses on processing the air filter components in the valve body 2 of the fan that has been running for a long time, so as to ensure the sustainable long-term operation of the fan while purifying the output gas. When more and more dust and impurities are attached to the filter 6, the induction component is used to sense it. As the impurities accumulate, the ventilation volume of the filter 6 decreases. When the wind force remains unchanged, the greater the thrust of the filter 6, the greater the thrust, which can overcome the pre-set elastic force and make the induction component sense it. When the induction component senses it, the operation of the fan can be suspended, and the filter 6 can be reset and quickly cleaned. The overall operation has the characteristics of automation and intelligence, and the filter 6 can be automatically cleaned and cleaned without manual processing, so that the convenience is better.

[0048] It is worth noting that the present embodiment also includes a rotating mechanism, a reciprocating component, a cleaning assembly and a linkage component.

[0049] In this embodiment, during actual use, when it is sensed that the filter 6 needs to be cleaned, the operation of the rotating mechanism drives the cleaning component to reciprocate and clean the impurities, dust and dirt on the filter 6 under the action of the reciprocating parts, and cooperates with the operation of the linkage parts to spray disinfectant to improve the cleaning effect and efficiency, and also can perform excellent disinfection operations on the impurity attachment area to avoid the growth of bacteria. The overall operation has excellent linkage and intelligence. At the same time, when the filter 6 is reciprocated and brushed, the filter 6 can also be shaken up and down, thereby improving the cleaning effect.

[0050] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Fig. 9The sensing component includes a frame 7, a filter screen 6 is slidably connected in the frame 7, a slider 8 is fixedly connected to the upper and lower surfaces of the frame 7, a slideway 9 is provided on the upper and lower surfaces of the inner wall of the valve body 2, the slider 8 slides on the inner wall of the slideway 9, an installation cavity is provided inside the valve body 2, an elastic telescopic member 10 is provided inside the installation cavity, an electric telescopic rod 11 is fixedly connected to the outer cylinder of the elastic telescopic member 10, the outer shell of the electric telescopic rod 11 is fixedly connected to the cavity wall of the installation cavity, the telescopic part of the elastic telescopic member 10 is fixedly connected to the side of the slider 8 on one side, a placement cavity is provided on the inner wall of the slideway 9, a trigger block 12 is installed on the cavity wall of the placement cavity, the sensing part of the trigger block 12 faces the slider 8, and when the slider 8 moves, it will contact the trigger block 12 on the other side, and when the trigger block 12 is pressed and triggered, the signal is transmitted to the control panel through the wireless signal transmitter.

[0051] In this embodiment, after the fan is used for a long time, a large amount of impurities and dirt may be attached to the filter 6, and when the fan is installed in a position that is not easy to clean, manual maintenance is more troublesome. Therefore, when a large amount of impurities are attached to the filter 6, the ventilation of the filter 6 is reduced, and the resistance of the filter 6 after being subjected to wind force becomes larger, which will overcome the elastic force of the elastic telescopic member 10, so that the filter 6 moves as a whole, and then the trigger block 12 on one side is separated from the slider 8, and the trigger block 12 on the other side is pressed and triggered by the slider 8, such as Fig. 9 As shown, at this time, the dust and impurities attached to the corresponding filter 6 have exceeded the standard, which may affect the air output of the fan, and the subsequent cleaning structure can be automatically controlled to process the filter 6. However, since the wind force to be output by the fan at this time may be small, and the corresponding filter 6 is blocked by impurities, and the small wind force is not enough to overcome the elastic force of the elastic telescopic member 10 to move the filter 6, and then through the operation of the telescopic part of the electric telescopic rod 11, the spring inside the elastic telescopic member 10 is compressed or not compressed, and then when the spring element is not compressed The filter 6 is easier to move when the wind output is smaller, and when the spring element is compressed, the filter 6 is more difficult to move and requires greater force, which corresponds to a larger wind output. Therefore, the overall sensing component has excellent adaptability to avoid the sudden movement of the filter 6, and two trigger blocks 12 are set to avoid the trigger block 12 on one side from being accidentally touched or impurities colliding with the trigger block 12 when the overall mechanism is running. It has a certain advantage of two-way trigger insurance, and the operation starts only when the trigger block 12 on the left side is triggered and the trigger block 12 on the right side is not triggered.

[0052] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The rotating mechanism includes a shell member 13, which is fixedly connected to the upper surface of the valve body 2, a motor 14 is fixedly connected to the inner wall of the shell member 13, a rotating part of the motor 14 is fixedly connected to a rotating shaft 19, and a cam 20 is fixedly connected to the outer surface of the rotating shaft 19.

[0053] In this embodiment, in actual use, when the sensing component senses that the filter 6 needs to be cleaned, the control panel controls the rotating part of the motor 14 to operate, and the rotating part of the motor 14 drives the rotating shaft 19 and the cam 20 to rotate.

[0054] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , the reciprocating parts include:

[0055] Two compression shells 21, the opposite sides of the two compression shells 21 are fixedly connected with electric telescopic rods 22, the ends of the electric telescopic rods 22 are fixedly connected with connecting pipes 23, the inner wall of the outer shell 13 is fixedly connected with a limiting member 24, the limiting member 24 and the compression shell 21, the side of the limiting member 24 is provided with a sliding opening for the connecting pipe 23 to pass through and be slidably connected, the cam 20 contacts the lower part of the compression shell 21, the electric telescopic rods 22 are located at the upper part of the compression shell 21, the outer surface of the compression shell 21 is provided with an opening 1 for the connecting pipe 23 on the opposite side to pass through and be slidably connected thereto, the outer surface of the connecting pipe 23 is fixedly connected with a spring 17, and the end of the spring 17 is fixedly connected to the side of the compression shell 21.

[0056] In this embodiment, as the cam 20 continues to rotate, when the long end of the cam 20 contacts the compression housing 21 on the right side, Figure 4As shown, the pressure shell 6 and the electric telescopic rod 22 and the connecting pipe 23 thereon will be driven to move to the right. When the long end of the cam 20 is pressed against the pressure shell 21 on the right side, the elastic reset of the spring 17 will reset the pressure shell 21. The same is true for the left side. The left and right pressure shells 21 are reciprocated horizontally to drive the cleaning component to reciprocate on the filter screen 6. Before operation, the contraction of the telescopic part of the electric telescopic rod 22 will give priority to the cleaning component to enter the interior of the valve body 2 first, so as to facilitate the subsequent cleaning operation. If this is not done, with the reciprocating movement of the pressure shell 21, the brush on it will be The bristles 26 come into contact with and press against the wall of the valve body 2 once during each reciprocating movement, and thus will suffer greater wear and tear after long-term use. In the present method, when it is sensed that the filter 6 needs to be cleaned, the left and right groups of bristles 26 can be continuously moved back and forth, thereby brushing off the impurities, dirt and dust attached to the filter 6 to achieve an excellent self-cleaning effect. The use of two groups of bristles 26 reduces the situation in which a single brush 26 occupies a large space when in use, and the reciprocating movement of the left and right groups of bristles 26 one after the other also avoids the situation in which components collide, thereby achieving an excellent cleaning effect.

[0057] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The cleaning assembly includes two brush blocks 25, the upper surface of the brush block 25 is fixedly connected to the end of the connecting pipe 23, the side of the brush block 25 facing the filter screen 6 is provided with bristles 26, and the side of the valve body 2 is provided with an opening 2 for the brush block 25 to penetrate and slide with it. The brush block 25 is L-shaped, and the side of the brush block 25 facing the filter screen 6 is provided with a plurality of openings 3.

[0058] In this embodiment, firstly, the brush block 25 is outside the valve body 2 when cleaning is not required due to the cooperation of the electric telescopic rod 22, thereby avoiding the situation where the brush block 25 blocks the air outlet and reduces the air outlet area, and the brush block 25 adopts an L-shaped design, such as Figure 6 and Figure 7 When cleaning is not needed, the brush block 25 can be used to block the inlet and outlet of the valve body 2 to prevent the wind from the fan from flowing out through the outlet.

[0059] When cleaning is needed, since the bristles 26 are located at the narrow side of the L-shaped brush block 25, there will be no excessive squeezing on the roots of the bristles 26, thereby avoiding significant wear and damage to the bristles 26. When the bristles 26 enter the valve body 2 for cleaning, they can also ensure sufficient contact and pressure between the bristles 26 and the filter screen 6 to ensure the cleaning effect.

[0060] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Fig.10 , the linkage components include:

[0061] The turntable 16, the center of the turntable 16 is fixedly connected to the end of the rotating shaft 19, a notch 27 is opened on the side of the turntable 16, a sphere is arranged at the mouth wall of the notch 27, a fixing rod 28 is fixedly connected to the side of the sphere, a piston head is fixedly connected to the end of the fixing rod 28, a piston cylinder 29 is slidably connected to the side of the piston head, the side of the piston cylinder 29 is fixedly connected to the upper surface of the valve body 2, the fixing rod 28 and the opposite side of the piston cylinder 29 are jointly fixedly connected with a spring 2 30, an input pipe 31 and an output pipe 32 are fixedly connected to the outer surface of the piston cylinder 29, a one-way valve is arranged inside the input pipe 31 and the output pipe 32, an end of the output pipe 32 is fixedly connected with a hose 33, an end of the hose 33 is fixedly connected with the side of the connecting pipe 23, an end of the input pipe 31 is fixedly connected with a container 34, and the outer shell of the container 34 is fixedly connected with the upper surface of the outer shell 13.

[0062] In this embodiment, the rotation of the rotating shaft 19 drives the turntable 16 to rotate, and due to the elastic relationship of the spring 2 30, the ball is always in contact with the side of the turntable 16, and the design of the recess 27 makes the ball and the fixed rod 28 move back and forth. During the reciprocating process, the piston head moves back and forth to change the internal pressure of the piston cylinder 29, so that the disinfectant in the container 34 is extracted through the input pipe 31, and outputted to the inside of the connecting pipe 23 through the piston cylinder 29, the output pipe 32 and the hose 33. In addition, due to the fixed connection relationship, the disinfectant will eventually pass through the opening on the brush block 25 toward The filter 6 is sprayed, and due to the arrangement of the plurality of openings 3, the disinfectant can be evenly sprayed on different positions of the filter 6 when the bristles 26 move back and forth. This method adopts the form of wet cleaning of impurities, and can simultaneously spray liquid onto the filter 6 when the bristles 26 move back and forth horizontally to clean the impurities, so as to soften the stubborn impurities and dirt and have a disinfecting effect, and then cooperate with the movement of contact brushing to quickly and effectively clean the impurities on the filter 6, and disinfect it at the same time. Different from the form of directly wiping the filter 6 with dry or wet methods, this method improves the cleaning effect and efficiency of the filter 6, and has a better cleaning effect on stubborn stains.

[0063] And: two magnet pieces 1 35 are fixedly connected to the outer surface of the turntable 16, and magnet piece 2 is fixedly connected to the upper surface of the filter screen 6. The lower end of magnet piece 1 35 is magnetically attracted to the upper end of magnet piece 2, and spring three 36 is fixedly connected to the opposite sides of the frame 7 and the filter screen 6.

[0064] In this embodiment, as the turntable 16 rotates, the magnet part 1 35 thereon rotates continuously. When the magnet part 1 35 rotates to the position closest to the magnet part 2, the filter 6 will overcome the elastic force of the spring three 36 under the magnetic attraction relationship, so that the filter 6 moves upward in the frame 7. As the turntable 16 continues to rotate, the magnetic attraction force decreases and is not enough to offset the elastic force, so that the filter 6 is reset downward. In this way, the filter 6 moves vertically back and forth, and cooperates with the horizontal reciprocating movement of the cleaning component to clean the dust, which is more helpful to clean up the dust and impurities. With the help of the spring and the magnetic attraction relationship, the filter 6 has a shaking nature when it moves vertically back and forth in a small amplitude, so as to further improve the impurity removal effect. Different from the reciprocating wiping of the filter 6 in a static state, it is inevitable that stubborn stains will be difficult to clean and dead corners will be cleaned. This method can increase the cleaning area and improve the cleaning effect and efficiency.

[0065] Working principle: When using the fan with air volume regulating valve function, there are the following steps:

[0066] Step S1: First, the machine body 1 is opened to compress the air and transport it toward the target area, and the valve body 2 can adjust the output of the gas and the direction of the output gas. The driving device 5 is operated by the control panel to achieve the purpose of air volume adjustment;

[0067] Step S2: With the continuous use of the fan, the filter 6 of the valve body 2 continuously filters impurities and dirt in the gas. When the fan is used for a long time, the accumulation of impurities on the filter 6 intensifies and affects the air volume output of the fan. At this time, the sensing component can be operated to sense whether the filter 6 needs to be cleaned by triggering, and transmit the signal to the control panel;

[0068] Step S3: The control panel first controls the fan to stop running, and immediately controls the rotating mechanism to operate. The rotating mechanism can drive the reciprocating component to operate, so that the cleaning component can reciprocate and clean the impurities attached to the surface of the filter 6, and the filter 6 can be vertically shaken during the cleaning time to cooperate with the cleaning;

[0069] Step S4: At the same time, the linkage component is driven by the rotating mechanism to spray disinfectant toward the surface of the filter 6 to improve the cleaning effect and have a disinfecting form. When everything is cleaned, the fan is restarted.

[0070] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
