Description

Technical Field

[0001] This utility model belongs to the field of sweeping machine technology, specifically relating to a dust bag for sweeping machines with a double-sealed structure. Background Technology

[0002] A robotic vacuum cleaner is a smart home appliance that uses built-in sensors, algorithms, and a cleaning system to autonomously perform tasks such as sweeping and mopping. With technological advancements, modern robotic vacuum cleaners now possess functions such as efficient cleaning, intelligent navigation, automatic obstacle avoidance, and automatic dust collection / mop washing, making them a powerful assistant in household cleaning.

[0003] The dust bag in a robotic vacuum cleaner is a component used to collect dust, hair, debris, and other waste. It's typically installed inside the robot's charging station and is a crucial accessory for modern robotic vacuum cleaners to achieve automated cleaning. The dust bag's main function is to collect and store the dust, debris, and other impurities absorbed by the robot during its cleaning process. When the robot returns to the charging station, it automatically empties the dust bag into a storage bin within the station, reducing the frequency of manual cleaning by the user.

[0004] Existing dust bag structures consist of a bag body and a clamping plate connected to the bag body. During use, the clamping plate must be bolted to the connection port of the vacuum cleaner. This structure is complex, time-consuming to install, and costly. The dust bag is only sealed with a simple sealing strip, resulting in poor sealing performance and leakage of dust and impurities. Therefore, it is of great importance to design a double-sealed structure dust bag for sweeping machines to solve the above-mentioned defects. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a dust bag for a sweeping machine with a double-sealed structure. The main body of this dust bag solves the problems of existing dust bag structures, which include a bag body and a clamping plate connected to the bag body. In use, the clamping plate needs to be bolted to install the dust bag onto the connection port of the vacuum cleaner. This structure is complex, time-consuming to install, and costly. The dust bag is only sealed with a simple sealing strip, resulting in poor sealing performance and leakage of dust and impurities.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a dust bag for a sweeping machine with a double-sealed structure. The dust bag for the sweeping machine includes a dust bag body; a connecting plate is fixedly connected to the top of the dust bag body; a sleeve is provided on the top of the connecting plate; an installation sleeve is provided above the sleeve; connecting components are provided on the top of the connecting plate and at both ends of the sleeve; a first sealing component is provided inside the sleeve; and a second sealing component is provided at the bottom of the connecting plate.

[0009] The connecting assembly is used to install the sleeve and the mounting sleeve. The connecting assembly consists of a fixed block, a rotating rod, a screw, a fixed rod, a rotating block, and two sets of limiting rods. The fixed block is fixedly connected to the top of the connecting plate and located on the outside of the sleeve. The rotating rod is rotatably connected to the inside of the fixed block. The screw is fixedly connected to one end of the rotating rod that extends into the inside of the fixed block. The fixed rod is slidably connected to the inside of the fixed block and threadedly connected to the end of the screw away from the rotating rod. The rotating block is fixedly connected to the end of the rotating rod away from the outside of the fixed block. The two sets of limiting rods are slidably connected to both ends inside the rotating block.

[0010] The first sealing assembly is used to increase the sealing performance of the connection between the sleeve and the mounting sleeve;

[0011] The second sealing assembly is used to increase the sealing performance of the connection between the connecting plate and the dust bag body.

[0012] When using the dust bag body of this technical solution, the sleeve is connected to the mounting sleeve. Pulling the connecting rod causes the two sets of limiting rods to move out of the limiting groove, allowing the rotating block to rotate. Rotating the rotating block causes the rotating rod to rotate, causing the screw to rotate, which in turn causes the fixed rod to move, limiting the connection between the fixed rod and the mounting groove. This allows the fixed rod to be limited to the mounting sleeve. The mounting sleeve is installed inside the sweeping robot, allowing the dust bag body to be installed inside the sweeping robot. When the fixed rod moves into the mounting groove, the first compression spring, in conjunction with the moving ring, can drive the limiting... The rod is displaced, moving the limiting rod into the limiting groove and connecting it with the fixing block to prevent the rotating rod from rotating. This limits the fixing rod, preventing it from moving and ensuring its stable installation inside the mounting groove. When the mounting sleeve connects with the sleeve, the mounting sleeve moves into the sleeve and compresses the two sets of first sealing rings. Multiple sets of second compression springs drive the first sealing rings to move, causing the connecting ring to move. This causes deformation through the deformation groove, fitting against the outer side of the mounting sleeve. Simultaneously, the elastic ring compresses the second sealing ring, causing it to fit against the surface of the mounting sleeve, thus ensuring a tight seal between the mounting sleeve and the sleeve.

[0013] Preferably, the mounting sleeve has mounting grooves at both ends, and the internal structure size of the mounting grooves corresponds to the external structure size of the fixing rod. The mounting sleeve is connected to the fixing rod through the mounting grooves.

[0014] Furthermore, a movable ring is fixedly connected to the outside of the limiting rod and inside the rotating block, and a first compression spring is sleeved on the outside of the movable ring and outside of the limiting rod. The two ends of the first compression spring are fixedly connected to the movable ring and the rotating block, respectively.

[0015] Furthermore, the two sets of limiting rods are connected by a connecting rod, and the connecting rod and the limiting rod are fixedly connected. The fixing block is connected to the limiting rod through a limiting groove.

[0016] Furthermore, the first sealing assembly consists of two sets of first sealing rings, multiple sets of connecting rings, two sets of second sealing rings, and two sets of elastic rings. The two sets of first sealing rings are slidably connected to the middle of the sleeve, the two sets of connecting rings are fixedly connected to the inside of the first sealing rings, the two sets of second sealing rings are fixedly connected to both ends of the sleeve, and the elastic rings are fixedly connected to the outside of the second sealing rings.

[0017] Furthermore, deformation grooves are provided at the ends of the two sets of connecting rings that are close to each other, and multiple sets of second compression springs are fixedly connected to the ends of the two sets of first sealing rings that are close to each other. The two sets of second compression springs are respectively fixedly connected to the two sets of first sealing rings.

[0018] Furthermore, the second sealing assembly consists of a fixed plate and two sets of sealing strips. The fixed plate is fixedly connected to the bottom of the connecting plate and located inside the dust bag body. The two sets of sealing strips are respectively fixedly connected to the fixed plate and the connecting plate at their respective ends that are close to each other.

[0019] (3) Beneficial effects

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. The dust bag body of this utility model, through the design of the connecting component, connects the sleeve and the mounting sleeve. Pulling the connecting rod drives the two sets of limiting rods to move out of the inside of the limiting groove, so that the rotating block can rotate. Rotating the rotating block drives the rotating rod to rotate, so that the screw rotates, which drives the fixed rod to move and limit the connection between the fixed rod and the mounting groove, so that the fixed rod can be limited to the mounting sleeve. When installing the dust bag body, the connecting component makes it easy to install the dust bag body. The installation steps are simple and do not require auxiliary tools, increasing the convenience of installation.

[0022] 2. The dust bag body of this utility model, through the design of the first sealing component and the second sealing component, can increase the sealing performance between the sleeve and the mounting sleeve when the sleeve and the mounting sleeve are connected, thereby increasing the sealing performance of the dust bag body. When the connecting plate and the mounting plate are connected to the dust bag body, the two sets of sealing strips can increase the sealing performance between the connecting plate and the mounting plate and the dust bag body, thereby increasing the sealing performance of the dust bag body. Through the double-layer sealing design, the sealing performance of the dust bag body can be effectively increased, preventing the problem of leakage of dust and impurities due to poor sealing performance.

Detailed Implementation

[0030] This specific embodiment is a dust bag for a double-sealed sweeping machine, and its structural schematic diagram is shown below. Figure 1-6 As shown, the dust bag for the sweeping machine includes a dust bag body 1; a connecting plate 2 is fixedly connected to the top of the dust bag body 1, a sleeve 3 is provided on the top of the connecting plate 2, an mounting sleeve 4 is provided above the sleeve 3, connecting components 5 are provided on the top of the connecting plate 2 and at both ends of the sleeve 3, a first sealing component 6 is provided inside the sleeve 3, and a second sealing component 7 is provided at the bottom of the connecting plate 2.

[0031] The connecting assembly 5 is used to install the sleeve 3 and the mounting sleeve 4. The connecting assembly 5 consists of a fixing block 8, a rotating rod 9, a screw 10, a fixing rod 11, a rotating block 12, and two sets of limiting rods 13. The fixing block 8 is fixedly connected to the top of the connecting plate 2 and located outside the sleeve 3. The rotating rod 9 is rotatably connected to the inside of the fixing block 8. The screw 10 is fixedly connected to one end of the rotating rod 9 that extends into the inside of the fixing block 8. The fixing rod 11 is slidably connected to the inside of the fixing block 8 and threadedly connected to the end of the screw 10 away from the rotating rod 9. The rotating block 12 is fixedly connected to one end of the rotating rod 9 away from the outside of the fixing block 8. The two sets of limiting rods 13 are slidably connected to both ends inside the rotating block 12.

[0032] The first sealing component 6 is used to increase the sealing performance of the connection between the sleeve 3 and the mounting sleeve 4;

[0033] The second sealing component 7 is used to increase the sealing performance of the connection between the connecting plate 2 and the dust bag body 1.

[0034] In this embodiment, both ends of the mounting sleeve 4 are provided with mounting grooves 14. The internal structure size of the mounting groove 14 is designed to correspond to the external structure size of the fixing rod 11. The mounting sleeve 4 is connected to the fixing rod 11 through the mounting groove 14, and the fixing rod 11 is limited to the mounting groove 14, so that the fixing rod 11 can be limited to the mounting sleeve 4. The mounting sleeve 4 is installed inside the sweeping robot, and the dust bag body 1 can be installed inside the sweeping robot through the mounting sleeve 4.

[0035] Secondly, in this embodiment, a moving ring 15 is fixedly connected to the outside of the limiting rod 13 and inside the rotating block 12. A first compression spring 16 is sleeved on the outside of the moving ring 15 and outside the limiting rod 13. The two ends of the first compression spring 16 are fixedly connected to the moving ring 15 and the rotating block 12 respectively. The first compression spring 16, in conjunction with the moving ring 15, can drive the limiting rod 13 to move.

[0036] Furthermore, in this embodiment, the two sets of limiting rods 13 are connected by a connecting rod 17. The connecting rod 17 and the limiting rods 13 are fixedly connected. The fixing block 8 is connected to the limiting rods 13 through a limiting groove. The limiting rods 13 are moved into the inside of the limiting groove and are connected to the fixing block 8 to limit the rotation of the rotating rod 9. The fixing rod 11 is limited so that it cannot move and is stably installed inside the mounting groove 14. Pulling the connecting rod 17 causes the two sets of limiting rods 13 to move out of the inside of the limiting groove, so that the rotating block 12 can rotate. Rotating the rotating block 12 causes the rotating rod 9 to rotate, so that the screw 10 rotates and causes the fixing rod 11 to move.

[0037] Furthermore, in this embodiment, the first sealing assembly 6 consists of two sets of first sealing rings 18, multiple sets of connecting rings 19, two sets of second sealing rings 20, and two sets of elastic rings 21. The two sets of first sealing rings 18 are slidably connected to the middle of the sleeve 3, the two sets of connecting rings 19 are fixedly connected to the inside of the first sealing rings 18, the two sets of second sealing rings 20 are respectively fixedly connected to both ends of the sleeve 3, and the elastic rings 21 are fixedly connected to the outside of the second sealing rings 20. When the sleeve 3 is connected to the mounting sleeve 4, the first sealing assembly 6 can increase the sealing between the sleeve 3 and the mounting sleeve 4, thereby increasing the sealing of the dust bag body 1.

[0038] Furthermore, in this embodiment, each of the two sets of connecting rings 19 has a deformation groove 22 at one end close to each other, and each of the two sets of first sealing rings 18 has multiple sets of second compression springs 23 fixedly connected to one end close to each other. The two sets of second compression springs 23 are respectively fixedly connected to the two sets of first sealing rings 18. When the mounting sleeve 4 is connected to the sleeve 3, the mounting sleeve 4 is displaced to the inside of the sleeve 3 to squeeze the two sets of first sealing rings 18. The multiple sets of second compression springs 23 drive the first sealing rings 18 to move, causing the connecting ring 19 to move. The deformation groove 22 generates deformation and fits the outside of the mounting sleeve 4. At the same time, the elastic ring 21 squeezes the second sealing ring 20, so that the second sealing ring 20 fits the surface of the mounting sleeve 4, thereby ensuring the sealing of the connection between the mounting sleeve 4 and the sleeve 3.

[0039] Furthermore, in this embodiment, the second sealing assembly 7 consists of a fixing plate 24 and two sets of sealing strips 25. The fixing plate 24 is fixedly connected to the bottom of the connecting plate 2 and located inside the dust bag body 1. The two sets of sealing strips 25 are respectively fixedly connected to the fixing plate 24 and the connecting plate 2 at their respective close ends. When the connecting plate 2 and the mounting plate are connected to the dust bag body 1, the two sets of sealing strips 25 can increase the sealing between the connecting plate 2 and the mounting plate and the dust bag body 1, thereby increasing the sealing performance of the dust bag body 1.

[0040] When using the device of this technical solution, the sleeve 3 is connected to the mounting sleeve 4. Pulling the connecting rod 17 causes the two sets of limiting rods 13 to move out of the limiting groove, allowing the rotating block 12 to rotate. Rotating the rotating block 12 causes the rotating rod 9 to rotate, causing the screw 10 to rotate, which in turn causes the fixed rod 11 to move, making the fixed rod 11 and the mounting groove 14 into a limiting connection, so that the fixed rod 11 can be limited to the mounting sleeve 4. The mounting sleeve 4 is installed inside the sweeping robot, and the dust bag body 1 can be installed inside the sweeping robot through the mounting sleeve 4. When the fixed rod 11 moves into the mounting groove 14, the first compression spring 16, in conjunction with the moving ring 15, can drive the limiting rod 13 to move into the limiting groove, making it limited to the fixed block 8, so that the rotating rod 9 cannot rotate. 1. Limiting the movement of the fixing rod 11 prevents it from moving, ensuring stable installation inside the mounting groove 14. When the mounting sleeve 4 connects to the sleeve 3, the mounting sleeve 4 displaces inside the sleeve 3, compressing two sets of first sealing rings 18. Multiple sets of second compression springs 23 drive the first sealing rings 18 to move, causing the connecting ring 19 to move. This causes deformation through the deformation groove 22, fitting the outer side of the mounting sleeve 4. Simultaneously, the elastic ring 21 compresses the second sealing ring 20, causing the second sealing ring 20 to fit against the surface of the mounting sleeve 4, thus improving the sealing of the connection between the mounting sleeve 4 and the sleeve 3. When the connecting plate 2 and the mounting plate connect to the dust bag body 1, two sets of sealing strips 25 increase the sealing between the connecting plate 2 and the mounting plate and the dust bag body 1, thereby increasing the sealing of the dust bag body 1. Compared with existing dust bags, this utility model improves the overall practicality of the dust bag through its design.

[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
