Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to a vacuum cleaner with a noise reduction structure. Background Technology

[0002] Vacuum cleaners, which use an electric motor to drive a fan and generate negative pressure to suck up dust and debris, are widely used in cleaning various areas of the home, offices, and vehicles. They offer advantages such as high cleaning efficiency, good results, ease of operation, and versatility (equipped with different nozzles to meet diverse needs). Vacuum cleaners are equipped with noise reduction structures, which not only enhance the user's comfort and convenience and reduce disturbance to others to create a harmonious environment, but also meet the increasingly stringent environmental and safety standards that people demand higher quality of living environments, ensuring the legal sale and use of the product.

[0003] A search revealed Chinese Patent Publication No. CN222444009U, which discloses a modular tubing for a vacuum cleaner. The tubing includes a vacuum cleaner body, a flexible hose, a handheld bend, a standard tube, a connecting tube head, and a suction head, all connected and fixed in sequence. This invention introduces a modular standard tube design, allowing users to freely combine multiple standard tube segments according to their individual needs and cleaning scenarios. This expands the vacuum cleaner's cleaning range and meets the needs of different users. The threaded connection and clamping mechanism design ensures a secure connection between the standard tube and adjacent pipes, effectively solving the problems of inconvenient support rod length adjustment and loose connections in traditional vacuum cleaners. It also reduces dust and debris overflow caused by long-term vibration of the vacuum cleaner body, improving the overall reliability of the vacuum cleaner and providing users with a better cleaning experience.

[0004] The aforementioned patent specification mentions that "by introducing a modular standard tube design, users can freely combine multiple standard tube segments according to their individual needs and cleaning scenarios, expanding the vacuum cleaner's cleaning range and meeting the needs of different users. The threaded connection and clamping mechanism design ensures a secure connection between the standard tube and adjacent tubes, effectively solving the problems of inconvenient support rod length adjustment and loose connections in traditional vacuum cleaners. This reduces dust and debris overflow caused by long-term vibration of the vacuum cleaner body, improving the overall reliability of the vacuum cleaner and providing users with a better cleaning experience." While the aforementioned patent can prevent dust and debris overflow, it cannot filter dust. Therefore, a vacuum cleaner with a noise reduction structure is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vacuum cleaner with a noise reduction structure, aiming to improve the problem that existing technologies cannot filter dust.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vacuum cleaner with a noise reduction structure includes a housing, a cleaning mechanism fixedly connected to the outer side of the housing, a filter structure fixedly connected to the inside of the cleaning mechanism, and a connecting mechanism fixedly connected to the outer side of the cleaning mechanism.

[0008] The filter structure includes a frame, a filter plate is slidably connected inside the frame, a connecting block is fixedly connected to the outside of the filter plate, a limiting component is slidably connected inside the connecting block, and a fixing block is fixedly connected to the outside of the cleaning mechanism.

[0009] Through the above technical solution: When the vacuum cleaner is working, the internal suction pump is activated, and the powerful suction acts on the ground through the cleaning mechanism to suck in dust and debris. The sucked-in dust enters the filter structure, where the filter plate intercepts and filters the dust within the frame. If the filter plate needs to be replaced, pull the limiting component in connecting block one to detach it from the fixing block, and the filter plate can be removed. During installation, slide the filter plate along the frame slide rail, then slide the limiting component back into connecting block one and insert it into the fixing block to fix the filter plate, continuously and effectively filtering dust and ensuring efficient cleaning and air purification by the vacuum cleaner.

[0010] As a further description of the above technical solution:

[0011] The limiting component includes a limiting rod, the outer side of which is slidably connected to the inside of the connecting block 1, a limiting block is fixedly connected to the outer side of the limiting rod, and a limiting ring is fixedly connected to the outer side of the limiting rod.

[0012] The above technical solution works as follows: When the filter plate needs to be removed, pull the limiting rod outward. The limiting rod slides within the connecting block, causing the outer limiting block and limiting ring to move synchronously. This allows one end of the limiting rod to detach from the fixed block, releasing the restriction on the filter plate. The filter plate can then be removed from the frame. When installing the filter plate, slide it into the frame and push the limiting rod in the opposite direction. The limiting rod causes the limiting block and limiting ring to return to their original positions, allowing the limiting rod to re-insert into the fixed block. The limiting block and limiting ring ensure the limiting rod is stable, thus firmly fixing the filter plate and ensuring the normal operation of the filtration structure.

[0013] As a further description of the above technical solution:

[0014] The cleaning mechanism includes an air pump, a transmission pipe is fixedly connected inside the air pump, a vacuum head is slidably connected to one end of the transmission pipe, a connecting shell is fixedly connected to the outside of the transmission pipe, and a storage box is fixedly connected to the outside of the air pump.

[0015] The above technical solution involves: starting the air pump to generate suction; bringing the vacuum head close to the area to be cleaned; sucking in dust and debris; and temporarily storing it in the storage box via the transmission tube. If the vacuum head needs to be replaced, it can be slid out from one end of the transmission tube. The connecting shell serves to connect and fix the vacuum head, ensuring stable operation of the cleaning mechanism and achieving efficient cleaning.

[0016] As a further description of the above technical solution:

[0017] The connecting mechanism includes a fixed shell, a rotating plate rotatably connected inside the fixed shell, a spring fixedly connected to one side of the rotating plate, a connecting block two fixedly connected to the side of the rotating plate away from the spring, three protrusions fixedly connected to the inner side of the connecting block two, and a limiting shell fixedly connected to the outer side of the transmission tube.

[0018] The above technical solution allows for the following: When replacing the vacuum head, press one side of the rotating plate connected to the spring. The spring is compressed, and the rotating plate rotates around the fixed shell, causing the protrusion on the connecting block two to disengage from the limiting shell, thus separating the vacuum head from the transmission tube. During installation, press the rotating plate again to align the vacuum head with the transmission tube. Release the rotating plate, and the spring will return, causing the protrusion to snap into the limiting shell to complete the alignment.

[0019] As a further description of the above technical solution:

[0020] The other end of the spring is fixedly connected to the inside of the fixed shell, and the outer side of the second connecting block is slidably connected to the inside of the limiting shell;

[0021] Through the above technical solution: pressing the rotating plate compresses the spring inside the fixed shell, causing the connecting block 2 to move outward, so that the outer side of the connecting block 2 slides out of the limiting shell, the protrusion disengages, and the separable component is released. Releasing the rotating plate causes the spring to rebound and extend, pushing the rotating plate to rotate in the opposite direction. The connecting block 2 slides into the limiting shell, and the protrusion is re-locked, achieving a stable connection of the components.

[0022] As a further description of the above technical solution:

[0023] The inner side of the limiting rod is slidably connected to the outer side of the connecting block 1, and the end of the limiting rod away from the limiting ring is slidably connected to the inside of the fixing block;

[0024] The above technical solution allows for the following steps: When the filter plate needs to be disassembled, pull the limiting rod outward to allow it to slide between the outer side of the connecting block and the inside of the fixing block. Once one end of the limiting rod is disengaged from the fixing block, the filter plate can be removed. During installation, push the limiting rod in the opposite direction to allow one end to slide into the fixing block, thus fixing the filter plate and ensuring that it remains stable while filtering dust.

[0025] As a further description of the above technical solution:

[0026] The outer side of the limiting block is slidably connected to the inside of the fixing block, and the outer side of the filter plate is slidably connected to the inside of the transmission tube;

[0027] The above technical solution involves starting the suction pump, allowing dust to enter through the suction head and transmission pipe. The filter plate intercepts the dust inside the transmission pipe. When the filter plate needs to be replaced, the limiting rod is pulled, causing the limiting block to slide and disengage within the fixed block, thus releasing the restriction on the filter plate. The filter plate is then slid out of the transmission pipe, cleaned, or replaced, and then slid back in. The limiting rod is then pushed to make the limiting block slide into the fixed block for fixation.

[0028] As a further description of the above technical solution:

[0029] The outer side of the suction pump is fixedly connected to the inside of the outer casing, and the bottom of the storage box is fixedly connected to the inside of the outer casing;

[0030] With the above technical solution: when the vacuum cleaner is turned on, the suction pump inside the outer shell operates to generate suction, which draws the dust in through the suction head and transmission tube. The outer shell provides a stable support for the suction pump. The dust drawn in enters the storage box with the airflow. The storage box is fixed at the bottom of the outer shell and is used to collect and temporarily store the dust for easy cleaning later, ensuring that the vacuum cleaner works continuously and stably.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, dust filtration is achieved by using a frame in conjunction with a filter plate, a filter plate in conjunction with a limiting rod, a limiting rod in conjunction with a limiting block and a limiting ring, and a limiting block in conjunction with a fixing block. The frame provides support for the filter plate, enabling it to be stably installed inside the vacuum cleaner pipe, ensuring filtration area and filtration effect. The filter plate can be selected with different materials and pore sizes as needed, effectively intercepting dust particles of various sizes, achieving high-efficiency filtration, and improving air quality.

[0033] 2. In this utility model, the fixed shell cooperates with the rotating plate, the rotating plate cooperates with the spring and the connecting block, the connecting block cooperates with the protrusion, and the protrusion cooperates with the limiting shell, thereby realizing the docking of the vacuum head and the transmission tube. Utilizing the lever principle of the rotating plate, the protrusion and the limiting shell can be easily separated or joined by pressing one end, making the disassembly and installation of the vacuum head simple and quick, without the need for complicated tools or cumbersome operations, which can greatly improve the efficiency of users replacing vacuum heads.

[0040] 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.

[0041] Reference Figures 1 to 3 The present invention provides an embodiment of a vacuum cleaner with a noise reduction structure, including a shell 1. The shell 1 provides a stable external protection and support structure for the entire vacuum cleaner, which can effectively resist minor collisions and scratches during daily use and ensure the safe operation of the internal mechanisms. A cleaning mechanism 2 is fixedly connected to the outside of the shell 1. The cleaning mechanism 2 is responsible for the core dust collection work of the vacuum cleaner. It generates a strong suction through the device to draw dust from different cleaning surfaces into the device, thus starting an efficient cleaning process. A filter structure 3 is fixedly connected inside the cleaning mechanism 2. When the vacuum cleaner is operating, the filter structure 3 accurately intercepts the dust drawn in, greatly purifies the drawn-in air, and avoids secondary pollution.

[0042] The cleaning mechanism 2 is fixedly connected to the outside of a connecting mechanism 4. The connecting mechanism 4 is used to easily connect or disassemble the device, enabling the vacuum cleaner to quickly adapt to different cleaning scenarios and improve its flexibility of use. The filter structure 3 includes a frame 301, which provides a stable installation base for the filter plate 302, ensuring that the filter plate 302 will not shake or shift during the filtration process and ensuring the stability of the filtration effect. The filter plate 302 is slidably connected inside the frame 301. The filter plate 302 can efficiently filter dust, debris and other impurities in the air, ensuring that the exhaust air is clean and improving indoor air quality. The filter plate 302 is fixedly connected to the outside of a connecting block 303, which serves as an intermediate connector to establish a tight connection between the filter plate 302 and the limiting component 305, making it convenient to fix and disassemble the filter plate 302.

[0043] A limiting component 305 is slidably connected inside the connecting block 303. The limiting component 305 can effectively limit the position of the filter plate 302 within the frame 301, ensuring it is stably positioned in the filtration position and guaranteeing normal filtration operation. A fixing block 304 is fixedly connected to the outside of the cleaning mechanism 2. The fixing block 304 works in conjunction with the limiting component 305 to provide a reliable fixing point for the limiting rod 3051, ensuring the stability of the filter plate 302 after installation. The limiting component 305 includes the limiting rod 3051. The limiting rod 3051 can slide within the connecting block 303 to fix and unlock the filter plate 302, making the operation simple and convenient.

[0044] The inner side of the limiting rod 3051 is slidably connected to the outer side of the connecting block 303. This connection method allows the limiting rod 3051 to flexibly control the installation and disassembly of the filter plate 302, facilitating maintenance and replacement of the filter plate 302. The outer side of the limiting rod 3051 is slidably connected to the inside of the connecting block 303, further enhancing the stability of the connection between the limiting rod 3051 and the connecting block 303, ensuring that it will not accidentally fall off during operation. The outer side of the limiting rod 3051 is fixedly connected to the limiting block 3052. The limiting block 3052 cooperates with the fixing block 304. When the limiting rod 3051 is inserted into the fixing block 304, it effectively prevents the limiting rod 3051 from excessive displacement, ensuring that the filter plate 302 is firmly fixed.

[0045] The outer side of the limiting block 3052 is slidably connected to the inside of the fixing block 304, providing a precise limiting function for the limiting rod 3051, ensuring that the filter plate 302 remains stable during operation and does not loosen. The outer side of the limiting rod 3051 is fixedly connected to a limiting ring 3053, which can play an auxiliary positioning and anti-dislodgement role during the sliding process of the limiting rod 3051, enhancing the overall reliability of the limiting assembly 305. The end of the limiting rod 3051 away from the limiting ring 3053 is slidably connected to the inside of the fixing block 304, so that the limiting rod 3051 can be stably inserted into the fixing block 304, achieving a firm and reliable fixing effect on the filter plate 302.

[0046] Specifically, the outer shell 1 is sturdy and durable, protecting the internal structure and providing stable support for the whole. Once the cleaning mechanism 2 is activated, it generates strong suction, drawing dust from various cleaning surfaces into the device for efficient dust collection. The sucked-in dust passes through the filter structure 3. The frame 301 securely mounts the filter plate 302, which efficiently intercepts dust, debris, and other impurities, purifying the air and preventing secondary pollution. Connecting block 1 303 connects the filter plate 302 to the limiting component 305. The limiting rod 3051 within the limiting component 305 slides inside and outside the connecting block 1 303, allowing for easy fixing and unlocking of the filter plate 302. The limiting block 3052 and the fixing block 304 work together to prevent excessive displacement of the limiting rod 3051, while the limiting ring 3053 assists in positioning and preventing detachment, ensuring stable operation of the filter plate 302. The connecting mechanism 4 allows for quick connection or disconnection of the vacuum head 205 through simple operation, enabling the vacuum cleaner to flexibly adapt to different cleaning scenarios, improving ease of use and flexibility. The coordinated operation of all structures ensures stable and efficient operation of the vacuum cleaner.

[0047] Reference Figure 1 , Figure 2 and Figure 4 The cleaning mechanism 2 includes an air pump 201, which serves as the power core of the vacuum cleaner. It generates strong and continuous suction to efficiently suck dust and other debris into the transmission pipe 202, ensuring that the vacuum cleaner has a good cleaning effect. The outer side of the air pump 201 is fixedly connected to the inside of the outer shell 1. The outer shell 1 provides a stable installation position for the air pump 201, effectively preventing the air pump 201 from shaking or shifting during operation and ensuring its stable operation. The transmission pipe 202 is fixedly connected inside the air pump 201. The transmission pipe 202 serves as a channel for conveying dust and other debris. Under the suction of the air pump 201, the dust sucked in from the vacuum head 205 can be quickly and smoothly transported to the storage box 203. The outer side of the filter plate 302 is slidably connected to the inside of the transmission pipe 202. When dust passes through the transmission pipe 202, the filter plate 302 can effectively intercept dust particles, ensuring that the air entering the storage box 203 is cleaner and preventing dust from escaping back into the air.

[0048] One end of the transmission tube 202 is slidably connected to a suction head 205. The suction head 205 can flexibly approach various cleaning surfaces, such as floors, sofas, and tabletops. The suction force generated by the air pump 201 is applied to the cleaning surface through the suction head 205 to accurately remove dust and debris. A connecting shell 204 is fixedly connected to the outside of the transmission tube 202. The connecting shell 204 serves to reinforce the structure of the transmission tube 202 and enhances the stability of the connection between the transmission tube 202 and the parts to a certain extent, ensuring the reliable operation of the entire vacuum cleaner. A storage box 203 is fixedly connected to the outside of the air pump 201. The storage box 203 is used to collect the dust and debris transported by the transmission tube 202. Its large capacity design can reduce the cleaning frequency and facilitate user use. The bottom of the storage box 203 is fixedly connected to the inside of the outer shell 1. The outer shell 1 provides stable support for the storage box 203, ensuring that the storage box 203 will not shake or tip over during dust collection, thus ensuring the safety of the vacuum cleaner during operation.

[0049] Specifically, the suction pump 201 is the core power source, fixed inside the outer casing 1 and operating stably to generate strong and continuous suction. The suction is transmitted through the transmission tube 202 to the suction head 205, which flexibly approaches the cleaning surface to precisely remove dust and debris. Dust is transported along the transmission tube 202, reinforced by the connecting shell 204 outside the transmission tube 202. During this process, the filter plate 302 inside the transmission tube 202 intercepts dust particles, purifying the air. Finally, the dust is collected in the storage box 203, a large-capacity storage box fixed to the bottom of the outer casing 1, ensuring stability and reducing cleaning frequency.

[0050] The connecting mechanism 4 includes a fixed shell 401, which provides a stable mounting base for the parts of the connecting mechanism 4, ensuring that the entire connecting structure is stable and reliable, and ensuring the smooth connection and separation of subsequent components. The fixed shell 401 is rotatably connected to a rotating plate 406, which can rotate within the fixed shell 401 to flexibly control the position of the connecting block 203, thereby facilitating the docking or separation of the vacuum cleaner head 205 and the transmission tube 202.

[0051] A spring 402 is fixedly connected to one side of the inside of the rotating plate 406. The spring 402 plays a key role in elastic reset in the entire connection mechanism 4. When an external force is applied to the rotating plate 406, the spring 402 is compressed and stores energy. After the external force is removed, it can push the rotating plate 406 back to its original position. The other end of the spring 402 is fixedly connected to the inside of the fixed shell 401. The fixed shell 401 provides a stable fixing point for the spring 402, so that the spring 402 can stably exert its elastic effect and ensure that the reset action of the rotating plate 406 is accurate and reliable. A connecting block 2 403 is fixedly connected to the side of the rotating plate 406 away from the spring 402. Under the drive of the rotating plate 406, the connecting block 2 403 can accurately control the position of the protrusion 404, thereby realizing precise control of the connection state between the vacuum head 205 and the transmission tube 202.

[0052] Three protrusions 404 are fixedly connected to the inner side of the connecting block 2 403. These three protrusions 404 cooperate with the limiting shell 405. By engaging or disengaging from the limiting shell 405, the connection between the vacuum cleaner head 205 and the transmission tube 202 can be firmly locked or released, ensuring the stability of the connection and the ease of separation. The limiting shell 405 is fixedly connected to the outer side of the transmission tube 202. The limiting shell 405 works in conjunction with the connecting block 2 403 and the protrusions 404 to provide a precise limiting structure for connecting the vacuum cleaner head 205 and the transmission tube 202, ensuring accurate positioning during connection and improving the reliability of the connection. The outer side of the connecting block 2 403 is slidably connected to the inside of the limiting shell 405. This sliding connection method allows the connecting block 2 403 to move smoothly within the limiting shell 405, ensuring that the protrusions 404 can be easily engaged or disengaged from the limiting shell 405, and efficiently completing the connection and separation operations between the vacuum cleaner head 205 and the transmission tube 202.

[0053] Specifically, the fixed housing 401 provides a stable installation base for the entire connection structure. A rotating plate 406 is rotatably connected inside the fixed housing 401, with a spring 402 connected to one side and fixed at the other end inside the fixed housing 401. The spring 402 acts as an elastic reset mechanism. When an external force is applied to the rotating plate 406, causing it to rotate, the spring 402 compresses and stores energy; when the external force is removed, it pushes the rotating plate 406 back to its original position. The rotating plate 406 drives the connecting block 403, precisely controlling the position of the three protrusions 404 fixed on the inner side. The limiting shell 405 on the outer side of the transmission pipe 202 works in conjunction with the connecting block 403 and the protrusions 404. By having the protrusions 404 engage or disengage from the limiting shell 405, the connection between the vacuum head 205 and the transmission pipe 202 is securely locked or released. The connecting block 403 slides within the limiting shell 405, ensuring efficient connection and disengagement operations.

[0054] Working principle: When a large amount of dust needs to be cleaned from the ground, the suction pump 201 is started. The suction force of the suction pump 201 draws the dust from the ground into the transmission pipe 202. The interior of the outer casing 1 is equipped with sound-absorbing cotton, which can block the noise generated by the suction pump 201, thus preventing excessive noise from inside the outer casing 1. When the dust passes through the transmission pipe 202, it encounters the filter plate 302 and is filtered by the filter plate 302. When the filter plate 302 needs to be replaced, the limiting rod 3051 can be pulled outward, causing one end of the limiting rod 3051 to move from the fixed block. When the filter plate 302 is detached from the inside of the frame 301, it is no longer restricted by the limiting rod 3051. It can then be removed from the inside of the transmission pipe 202 via the connecting block 303 for cleaning or replacement. When the filter plate 302 needs to be put back, it can be aligned with the outer side of the filter plate 302 and the sliding groove opened inside the transmission pipe 202, and then slid into the frame 301. The limiting rod 3051 is then passed through the inside of the connecting block 303 to restrict the filter plate 302 inside the transmission pipe 202, thereby achieving dust filtration.

[0055] When the vacuum head 205 needs to be replaced, one end of the rotating plate 406 near the vacuum head 205 can be pressed downwards to press it into the interior of the fixing shell 401. The other end of the rotating plate 406 is fixedly connected to the connecting block 403. This will cause the connecting block 403 to drive the protrusion 404, thereby disengaging the interior of the fixing shell 405. The fixing shell 405 is connected to the outside of the transmission tube 202. At this time, the vacuum head 205 can be separated from the transmission tube 202. The vacuum head 205 then needs to be replaced again. When the dust head 205 is reinstalled, one end of the rotating plate 406 can be pressed down again, causing the rotating plate 406 to tilt upwards like a seesaw. At this point, the dust head 205 can be connected to the transmission tube 202. Then, the rotating plate 406 is released, and the spring 402 at the bottom of the rotating plate 406 will push the rotating plate 406 up, thereby pushing the end with the protrusion 404 on the other side into the interior of the limiting shell 405, thus completing the connection between the dust head 205 and the transmission tube 202.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
