Description

Technical Field

[0001] The present invention relates to the technical field of cleaning instruments, and particularly to an oblique beating structure and a cleaning device. Background Art

[0002] As a household appliance, the mite remover is popular among users because it can effectively remove dust and mites on furniture such as beds and sofas. Its core working principle includes three aspects: beating, dust suction, and sterilization. Among them, the beating function is crucial for improving the cleaning effect. The primary generation of mite removers realized the beating function through beating blocks driven by vibration motors. However, with technological progress, most current mainstream products use roller brushes to complete this task to obtain a higher beating frequency and stronger beating force.

[0003] However, the high-speed rotation of the roller brush and its flexible connection method with the body are the main reasons for noise and hair entanglement. In addition, the beating blocks in traditional designs need to occupy a large space and are fixed to the body far from the dust suction port, resulting in the dispersion of vibration force and being unable to efficiently send the beaten dust and mites directly into the dust suction system, thereby reducing the overall effect of mite removal and dust cleaning. Specifically, the high-speed rotating roller brush not only generates significant noise during operation but also makes soft fabrics such as hair easily entangle on it due to the Coanda effect and friction, and may roll up quilts or sheets during operation, further affecting the user experience. These problems together limit the performance and efficiency of existing mite removers.

[0004] In addition, the industry has started to study soft bristle low-speed roller brushes and strengthen the beating force of beating blocks. For example, a mite remover disclosed in Chinese Patent CN209135200U drives the roller brush through a motor with spline shafts at both ends, drives the roller brush through a synchronous pulley and a synchronous belt, and drives the beating device to reciprocate relative to the housing through the synchronous pulley, synchronous belt, and eccentric shaft to realize the beating of the mattress, sofa, or carpet. This synchronous transmission and cooperation of the beating device and the roller have higher working efficiency. However, in this solution, the roller brush rotates too fast, resulting in the rolling of sheets, the beating block has a fast beating speed and a large contact surface, resulting in large beating noise, and the beating device occupies a large space, is far from the suction port, and the mites beaten by vibration cannot be effectively transmitted to the suction port, and the mite removal and dust cleaning effect is not good.

[0005] Therefore, it is necessary to design a new structure to achieve the technical effects of strong beating vibration, close to the dust suction port, good mite removal and dust cleaning effect, and low beating noise, and solve the technical problems of poor dust cleaning effect caused by the large space occupied by the linear beating mechanism of the mite remover and its distance from the suction port and large beating noise caused by the large beating contact surface in the prior art. Summary of the Invention

[0017] The beneficial effects of the present invention compared with the prior art are as follows: By providing a flapping drive structure connected to the flapping plate and a flapping plate designed in an oval shape, the flapping plate is assembled in an inclined installation groove provided in the main body bottom case, enabling the flapping plate to reciprocate along an inclined path.

In addition, the oblique flapping method enhances the vertical flapping force on the cleaning surface, further improving the deep mite removal effect, effectively solving the problems of large occupied space, poor dust removal effect due to being far from the suction port, and high noise caused by large flapping contact surface in the existing linear flapping mechanism.

[0025] As a household appliance, the mite remover is widely popular because it can effectively remove dust and dust mites on furniture such as beds and sofas. Its core working principles include beating, dust suction, and sterilization. The first-generation products achieved the beating function through the beating blocks driven by vibration motors, but most modern mainstream products use roller brushes to obtain higher beating frequencies and stronger forces. However, the high-speed rotation of the roller brush and its flexible connection method with the body have led to problems such as noise and hair entanglement. Moreover, since the beating blocks need to occupy a large space and are fixed on the body far away from the dust suction port 21, the vibration force is dispersed, and it is impossible to efficiently send the lifted dust and dust mites into the dust suction system, reducing the overall cleaning effect. In addition, although the industry has tried to improve these problems by using soft-bristle low-speed roller brushes and enhancing the beating force, although synchronous transmission has been achieved to improve work efficiency, there are still problems such as sheet rolling, loud beating noise, and the beating device being far from the suction port, which limit the mite and dust removal effect and the user experience.

[0026] Therefore, the embodiment of the present invention provides an oblique beating structure 1 and a cleaning device, achieving technical effects such as strong beating vibration, close to the dust suction port 21, good mite and dust removal effect, and low beating noise, and solving the technical problems in the prior art that the linear beating mechanism of the mite remover occupies a large space, is far from the suction port, resulting in poor dust removal effect, and has a large beating contact surface resulting in loud beating noise.

[0027] Specifically, by using the oval beating plate 10 in cooperation with the inclined installation groove 31 in the main body bottom shell 3, the beating plate 10 is assembled compactly and close to the dust suction port 21, effectively solving the problems that the traditional linear beating mechanism occupies a large space and is far from the suction port, resulting in poor dust removal effect. At the same time, by using a driving assembly including a power source 50, a transmission bracket 60, and a transmission structure 70, the beating plate 10 is driven through a connecting rod 20 and an eccentric wheel 30, which not only ensures the intensity of the beating vibration but also reduces the beating contact surface due to the structural design, thereby reducing the beating noise. In addition, through reasonable transmission design, the oblique beating structure 1 and the roller brush assembly 4 work together, further enhancing the overall effect of mite and dust removal and providing an efficient and low-noise cleaning solution. This design not only improves the work efficiency of the device but also significantly improves the user experience.

[0028] To better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the accompanying drawings of the specification and specific embodiments.

[0029] Please refer to Figures 1 to 3 , the above-mentioned oblique beating structure 1 includes: a beating driving structure and a beating plate 10; the beating driving structure is connected to the beating plate 10; the shape of the beating plate 10 is oval; the beating plate 10 is assembled in the main body bottom shell 3, and the main body bottom shell 3 is provided with an inclined installation groove 31, and the beating plate 10 is placed in the installation groove 31.

[0030] In this embodiment, the shape of the flapping plate 10 is designed to be oval, and this unique shape helps to change the traditional surface contact into line contact, thus effectively reducing the noise generated by large-area flapping while ensuring the flapping amplitude and frequency. In addition, the oval design makes the flapping plate 10 more compact, which is beneficial to reducing the size of the entire device and making it more suitable for the design requirements with limited space.

[0031] The flapping drive structure is directly connected to the flapping plate 10 to drive the flapping plate 10. This drive mechanism enables the flapping plate 10 to reciprocate along the inclined installation groove 31 inside the main body housing 3. Specifically, when the motor is started, through a series of transmission components, the eccentric wheel 30 in the link mechanism 77 is finally driven to rotate, which in turn causes the connecting rod 20 to move up and down, driving the flapping plate 10 to achieve an oblique reciprocating motion. This design not only realizes strong flapping vibration, but also greatly enhances the mite and dust removal effect due to its position close to the dust suction port 21.

[0032] The flapping plate 10 is assembled inside the main body housing 3, and an inclined installation groove 31 is specially provided inside the main body housing 3 to adapt to the oblique movement track of the flapping plate 10. This design ensures that the flapping plate 10 can operate efficiently within a limited space, while avoiding unnecessary mechanical friction and energy loss. In this way, the oblique flapping structure 1 effectively solves the problems of large occupied space and far distance from the suction port existing in the traditional linear flapping mechanism, and significantly improves the overall performance of the device.

[0033] In summary, the structure of this embodiment realizes the technical effects of strong flapping vibration, close to the dust suction port 21, good mite and dust removal effect, and low flapping noise through the careful design of the shape, drive mode and installation position of the flapping plate 10, representing an effective solution to the problems of the existing technology.

[0034] In one embodiment, please refer to Figure 3 and Figure 4 The above-mentioned flapping drive structure includes a connection structure and a drive component, and the drive component is connected to the connection structure; the connection structure is connected to the flapping plate 10.

[0035] In this embodiment, the flapping drive structure is composed of a drive component and a connection structure, which is responsible for converting the rotational motion of the motor into the reciprocating oblique motion of the flapping plate 10. The connection structure is the bridge between the drive component and the flapping plate 10, ensuring that the power can be accurately transmitted to the flapping plate 10 so that it can work according to the design requirements.

[0036] In one embodiment, please refer to Figure 3 and Figure 4, the above connection structure includes a link mechanism 77 and a fixed shaft 40. The link mechanism 77 includes a connecting rod 20. The fixed shaft 40 is inserted into the beating plate 10, and the connecting rod 20 is connected to the fixed shaft 40.

[0037] In this embodiment, the fixed shaft 40 is installed at the central axis position of the beating plate 10.

[0038] In this embodiment, the link mechanism 77 is responsible for converting the rotational motion of the eccentric wheel 30 into the linear reciprocating motion of the beating plate 10. Its design needs to ensure the effective transmission of force and the stable operation of the beating plate 10.

[0039] The fixed shaft 40 is installed at the central axis position of the beating plate 10, playing a role of positioning and supporting, enabling the beating plate 10 to accurately perform an oblique motion within the inclined installation groove 31 of the main machine bottom shell 3.

[0040] In one embodiment, please refer to Figure 3 and Figure 4 , the above drive structure includes a power source 50, a transmission bracket 60, and a transmission structure 70; the power source 50 is assembled on the transmission bracket 60, the power source 50 is connected to the transmission structure 70; the transmission structure 70 is connected to the connection structure.

[0041] In this embodiment, the power source 50 refers to an electric motor, which is the energy source of the entire system and provides the necessary driving force.

[0042] The transmission bracket 60 is used to stably install the power source 50 and other transmission components, ensuring that they can work together without displacement or vibration.

[0043] The transmission structure 70 includes a series of mechanical elements (such as belts, gears, etc.), which are used to adjust the speed ratio and effectively transmit the power from the power source 50 to the connection structure.

[0044] In one embodiment, please refer to Figure 3 and Figure 4 , the above drive structure further includes a connecting shaft 80, and the transmission structure 70 is connected to the connection structure through the connecting shaft 80.

[0045] In this embodiment, the connecting shaft 80 serves as a link between the transmission structure 70 and the link mechanism 77. It transmits the energy from the power source 50 to the link mechanism 77, thereby driving the beating plate 10 to perform reciprocating motion.

[0046] In one embodiment, please refer to Figure 3 and Figure 4 , the above transmission structure 70 includes a driving gear 71, the driving gear 71 is connected to the power source 50; the driving gear 71 is connected to the connecting shaft 80.

[0047] In this embodiment, the driving gear 71 is directly connected to the power source 50, receives the rotational force from the motor, and transmits this rotational force by engaging with other gears or directly driving the connecting shaft 80.

[0048] In one embodiment, please refer to Figure 3 and Figure 4 , the above-mentioned link mechanism 77 further includes an eccentric wheel 30, the eccentric wheel 30 is connected to the connecting shaft 80; the eccentric wheel 30 is connected to the link 20.

[0049] In this embodiment, the eccentric wheel 30 is a key component. Its special shape enables the link 20 to move up and down when the connecting shaft 80 rotates, thereby pushing the flapping plate 10 to perform an oblique reciprocating motion. The design of the eccentric wheel 30 is crucial for controlling the flapping force and frequency.

[0050] In summary, through the carefully designed technical features in this embodiment, especially the cooperation of key components such as the link 20, the fixed shaft 40, and the eccentric wheel 30, an efficient oblique flapping function is achieved, solving the problems of large space occupation, poor dust removal effect, and high noise existing in traditional linear flapping mechanisms.

[0051] In one embodiment, please refer to Figure 5 and Figure 6 , a guiding notch 33 is provided on the side wall of the above-mentioned mounting groove 31. When installing the oblique flapping structure 1, after first installing the flapping driving structure in place, pass the fixed shaft 40 through the middle of the flapping plate 10, then obliquely insert one end of the fixed shaft 40, and hard squeeze and insert the other end of the fixed shaft 40.

[0052] Specifically, first ensure that the flapping driving structure has been correctly installed in the designated position, and all connecting parts such as screws and nuts have been tightened in place. This step is the basis for ensuring the stable operation of the entire system, ensuring that there will be no movement or misalignment during subsequent operations.

[0053] Next, take the fixed shaft 40 and pass it through the middle of the flapping plate 10; ensure that the fixed shaft 40 completely penetrates the flapping plate 10; align the end of the fixed shaft 40 that has passed through the flapping plate 10 with the guiding notch 33 on the side wall of the mounting groove 31. Due to the existence of the guiding notch 33, this step can more accurately guide the fixed shaft 40 into the mounting groove 31. Adopting the oblique insertion method can effectively reduce the friction force during the initial contact, facilitating a smoother start of the assembly process.

[0054] After the preliminary positioning is completed, appropriate pressure needs to be applied so that the other end of the fixed shaft 40 is also fully embedded in the installation groove 31. This process may require a certain amount of force to overcome the resistance inside the installation groove 31, but be sure to operate carefully to avoid damaging the components. Use appropriate tools or apply force manually until the fixed shaft 40 is firmly fixed in the installation groove 31.

[0055] Once the fixed shaft 40 is successfully inserted and in place, check whether it is accurately located at the predetermined position and whether it fits tightly with the installation groove 31 and other components. In addition, it is also necessary to verify the overall stability of the flapping plate 10 and its driving structure to ensure that there are no loosening or deviation phenomena.

[0056] Through the above steps, the installation of the diagonal flapping structure 1 is completed. This design not only simplifies the assembly process but also improves the stability and reliability of the system, enabling the diagonal flapping mechanism to operate efficiently within the main body housing 3. During the entire installation process, pay attention to following the correct sequence and methods to ensure the best installation effect.

[0057] In this embodiment, to solve the problems in the prior art that the linear flapping mechanism of the mite remover occupies a large space, is far from the suction port resulting in poor dust removal effect, and has a large flapping contact surface causing large flapping noise, a structure is adopted in which the eccentric wheel 30 drives the connecting rod 20 to make the conical flapping plate 10 flap obliquely. This design achieves the technical effects of strong flapping vibration, being close to the dust suction port 21, good mite and dust removal effects, and low flapping noise.

[0058] The flapping plate 10 is installed in the main body housing 3 through the fixed shaft 40, and has the function of making the elliptical flapping plate 10 reciprocate along the inclined installation groove 31 of the main body housing 3.

[0059] The space formed by the roller brush cover assembly 2 and the main body housing 3 has the functions of forming a flapping action cavity and a flapping air flow passage.

[0060] The diagonal flapping structure 1 has the functions of driving the roller brush assembly 4, obliquely flapping to lift dust, having strong flapping vibration, and deeply removing mites.

[0061] Specifically, a groove 11 is provided on the flapping plate 10. One end of the connecting rod 20 is aligned and connected with the groove 11 of the flapping plate 10, and the other end of the connecting rod 20 is connected with the connecting shaft 80. The fixed shaft 40 is laterally inserted into the flapping plate 10, connected and fixed with the connecting rod 20, and the assembly is obliquely inserted into the installation groove 31 of the main body housing 3.

[0062] The driving gear 71 connected to the motor drives the belt, the connecting shaft gear 72 and the connecting shaft 80, the eccentric wheel 30, and the bearing connected thereto to make the connecting rod 20 perform a circular motion. At the same time, through the limiting action of the installation groove 31 of the main body housing 3, the conical flapping plate 10 realizes an oblique reciprocating motion.

[0063] During specific operation, when the motor starts, the driving gear 71 fixed to the motor rotates, drives the connecting shaft gear 72 to rotate through the belt, and then drives the driven gear 73 connected to the brush driving rod 78 in the brush assembly 4 to rotate through the belt. Since the connecting shaft 80 and the connecting shaft gear 72 are fixedly connected, the rotation of the connecting shaft gear 72 drives the connecting shaft 80 to rotate. The connecting shaft 80 is fixedly connected to the connecting rod 20. When the connecting shaft gear 72 rotates driven by the motor, the connecting shaft 80 can rotate on the transmission bracket 60 through the bearing, and then drives the connecting rod 20 to rotate. The rotation of the eccentric wheel 30 can realize the up and down movement of the connecting rod 20, and then drive the flapping plate 10 to move up and down, vertically flapping the cleaning surface, specifically presenting as a flapping state and a retracted state, as Figure 7 and Figure 8 shown.

[0064] The flapping plate 10 adopts an elliptical shape and moves obliquely, improving from the traditional surface contact to line contact. At the same eccentric movement distance, it does not affect the amplitude and frequency of flapping, and at the same time effectively reduces flapping noise. In addition, the oblique flapping is closer to the dust suction port 21 than the large surface flapping plate 10, and can effectively improve the effect of strong deep flapping for mite removal.

[0065] Through the above design, not only the problems in the prior art are solved, but also the overall performance and user experience of the mite remover are improved.

[0066] In an embodiment, the driving gear 71 is connected to the connecting shaft gear 72 through a belt. In addition, the connecting shaft gear 72 is connected to the driven gear 73 through a belt, and the connecting shaft gear 72 is actually a gear set formed by a large gear and a small gear. One end of the connecting shaft 80 passes through the driven gear 73 and is connected through a retaining piece 74 and a screw 75; a circlip 76 and a bearing are connected to one end of the connecting shaft 80 connected to the eccentric wheel 30, and a bearing is also connected to the other end of the eccentric wheel 30.

[0067] The above-mentioned diagonal flapping structure 1, by setting a flapping drive structure connected to the flapping plate 10 and a flapping plate 10 designed in an oval shape, and the flapping plate 10 is assembled in an inclined installation groove 31 provided in the main body bottom shell 3, so that the flapping plate 10 can reciprocate along an inclined path; this design not only reduces the occupied space of the entire mechanism, but also makes the flapping plate 10 closer to the dust suction port 21, thereby improving the dust removal effect; at the same time, since the flapping plate 10 adopts an elliptical shape and works in a line contact manner, on the premise of ensuring that the flapping amplitude and frequency remain unchanged, the noise problem caused by traditional surface contact is significantly reduced. In addition, the diagonal flapping method enhances the vertical flapping force on the cleaning surface, further improving the effect of deep mite removal, effectively solving the problems of large occupied space, poor dust removal effect due to being far from the suction port, and high noise caused by large flapping contact surface existing in the linear flapping mechanism in the prior art.

[0068] In one embodiment, as Figure 9 shown, a cleaning device is further provided, including a roller brush cover assembly 2, a main body bottom shell 3, a roller brush assembly 4, and the above-mentioned diagonal flapping structure 1; the diagonal flapping structure 1 is connected to the roller brush assembly 4; the roller brush assembly 4 and the roller brush cover assembly 2 are respectively assembled on the main body bottom shell 3, and the roller brush cover assembly 2 is assembled at the front end of the roller brush assembly 4.

[0069] In one embodiment, please refer to Figure 4 , the transmission component includes a driven gear 73, and the driving gear 71 is in transmission connection with the driven gear 73; the driven gear 73 is connected to the roller brush assembly 4.

[0070] In one embodiment, please refer to Figure 9 , a dust suction port 21 is provided on the roller brush cover assembly 2, and an air duct opening 32 is provided at the front end of the main body bottom shell 3, and the flapping plate 10 is close to the dust suction port 21 and the air duct opening 32.

[0071] Specifically, the roller brush cover assembly 2 is located at the front end of the device, and a dust suction port 21 is provided thereon. This assembly not only protects the internal mechanical structure but also guides dust into the device.

[0072] The main body bottom shell 3 serves as the main support structure of the device, and it includes two key parts: A roller brush cavity 34 for accommodating the roller brush assembly 4, ensuring that the roller brush can rotate freely to deeply clean the fabric surface.

[0073] An installation groove 31 is provided for fixing and limiting the movement direction of the conical flapping plate 10 to ensure that it reciprocates obliquely along the designed path.

[0074] The rotary brush assembly 4 is connected to the driven gear 73 and rotates to loosen the dust and mites deep in the fabric. This assembly is directly installed in the rotary brush cavity 34 inside the main body housing 3 and closely cooperates with the diagonal flapping structure 1. The driving gear 71 and the driven gear 73 are connected by a conveyor belt. The driving gear 71 is connected to the motor output shaft. When the motor starts, the driving gear 71 rotates and drives the driven gear 73 to rotate through the conveyor belt. The driven gear 73 is directly connected to the rotary brush assembly 4, thereby transmitting power to the rotary brush and making it start to rotate and work.

[0075] The diagonal flapping structure 1 enables the conical flapping plate 10 to reciprocate along the diagonal installation groove 31 on the main body housing 3 through the connecting rod 20. This design makes the flapping more efficient and the noise lower.

[0076] The rotary brush cover assembly 2 is installed at the front end of the rotary brush assembly 4, so that while the rotary brush is working, the dust and mites loosened can be timely sucked through the dust suction port 21 thereon.

[0077] A air duct opening 32 is specially provided at the front end of the main body housing 3 to ensure that the sucked dust can be quickly and effectively collected into the dust collection bag or dust collection box. At the same time, since the flapping plate 10 is close to the dust suction port 21 and the air duct opening 32, this greatly improves the capture efficiency of dust and mites.

[0078] After the device is started, the motor first drives the driving gear 71 to rotate, and then drives the driven gear 73 through the conveyor belt, so that the rotary brush assembly 4 starts to rotate. At the same time, the motor also drives the connecting rod 20 in the diagonal flapping structure 1, so that the flapping plate 10 reciprocates along the preset diagonal trajectory. This combined action can not only effectively loosen the deep dust and mites, but also quickly suck them away through the dust suction port 21 to avoid secondary pollution.

[0079] In summary, as Figure 8 and Figure 9 shown, the occupied space of the diagonal flapping plate 10 is smaller than that of the vertical flapping plate 10, and the flapping noise is also significantly reduced. In this embodiment, by optimizing the design and layout of each component, especially by introducing the diagonal flapping structure 1, the overall performance of the cleaning device is significantly improved. It not only improves the efficiency of mite and dust removal, but also reduces the operating noise, providing a better user experience for users.

[0080] This cleaning device optimizes the design and layout of each component by integrating the roller brush cover assembly 2, the main body bottom shell 3, the roller brush assembly 4, and the innovative diagonal flapping structure 1. It not only improves the dust mite and dust removal efficiency but also reduces the operating noise. The roller brush assembly 4 and the diagonal flapping structure 1 cooperate closely to effectively loosen and collect the dust and mites deep in the fabric, while the air duct opening 32 provided at the front end of the main body bottom shell 3 ensures the rapid collection of dust and avoids secondary pollution, overall enhancing the user experience. This design is particularly suitable for household users who pursue efficient cleaning and low-noise operation.
