A new type of vacuum cleaner

Abstract

A novel vacuum cleaner includes a suction component, a body, a roller brush component, and a locking component. The top of the body has a handle for holding the suction component, and the bottom of the body has a suction port communicating with the suction component. The roller brush component is located beside the suction port and includes a linkage cylinder and a roller brush body. The linkage cylinder is rotatably mounted on the bottom of the body, and the roller brush body is hollow and can be fitted onto or detached from the linkage cylinder. The locking component includes a separating sleeve, a locking rod, and a self-locking snap-fit ​​with locked and unlocked states. The separating sleeve is slidably mounted inside the linkage cylinder and fixed to the self-locking snap-fit. The separating sleeve has an elastic strip with a locking block. The locking rod is located inside the roller brush body and has a locking slot. Pushing the roller brush body causes the locking rod to press the separating sleeve to move, switching the state of the self-locking snap-fit. This causes the elastic strip to be located inside the linkage cylinder and drive the locking block to engage with the locking slot, thus fixing the roller brush body to the linkage cylinder. Alternatively, the elastic strip can protrude from the linkage cylinder and drive the locking block to disengage from the locking slot, thus removing the roller brush body.

Description

Technical Field

[0001] This utility model belongs to the technical field of floor cleaning equipment, and in particular relates to a novel vacuum cleaner. Background Technology

[0002] A vacuum cleaner is a floor cleaning device that mainly consists of a roller brush and a body with a built-in suction component. The roller brush is rotatably mounted on the body, and the body has a suction port corresponding to the center of the roller brush and connecting the suction component and the roller brush. The roller brush rubs against the ground to loosen the dust and debris. The built-in suction component then generates negative air pressure, which draws the loose dust and debris into the body through the suction port to complete the cleaning operation.

[0003] Existing vacuum cleaners typically have a locking hole at the bottom of the body and a locking pin at the end of the roller brush. The roller brush is detached from the body by rotatably inserting the locking pin into the locking hole. This structure is simple and easy to manufacture. However, in actual use, it has been found to have at least the following problems: Firstly, the engagement points between the clip shaft and the clip hole are usually set quite firmly, requiring users to use considerable force to disassemble and assemble the roller brush, resulting in a poor user experience.

[0004] Secondly, during long-term disassembly and use, the retaining shaft and retaining hole are prone to wear, causing the roller brush to loosen or detach directly from the machine body, resulting in a shorter service life. Utility Model Content

[0005] (a) Technical problems to be solved This invention provides a novel vacuum cleaner that can solve the problems mentioned in the background art.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A novel vacuum cleaner includes a suction component, a body, a roller brush assembly, and a locking component. A handle is optionally mounted on the top of the body. The suction component is installed inside the body or the handle. The bottom of the body has a suction port connecting the suction component to the outside. The roller brush assembly is located beside the suction port and includes a linkage cylinder and a roller brush body. The linkage cylinder is rotatably mounted on the bottom of the body. The roller brush body is hollow and can be fitted onto or detached from the linkage cylinder. The locking component includes a release sleeve, a locking rod, and a press-to-lock buckle with locked and unlocked states. The release sleeve is slidably mounted inside the linkage cylinder and fixed to the press-to-lock buckle. The device includes a snap-fit ​​mechanism, and the separating sleeve is also equipped with an elastic strip with a locking block. The locking rod is located inside the roller brush body and has a locking slot. Pushing the roller brush body can cause the locking rod to press the separating sleeve to move, thereby switching the state of the press-locking snap-fit. When the press-locking snap-fit ​​is in the locked state, the elastic strip is located inside the linkage cylinder and deforms adaptively, causing the locking block to insert into the locking rod's slot, thus fixing the roller brush body to the linkage cylinder. When the press-locking snap-fit ​​is in the unlocked state, the elastic strip protrudes outside the linkage cylinder and returns to its original shape, causing the locking block to disengage from the locking rod's slot, thus disassembling the roller brush body.

The roller brush body also has a fluff layer that completely fills the outer wall of the roller brush body and avoids the spiral scraper, forming a spiral groove on the roller brush body. Furthermore, each segment of the fluff layer has the same cross-sectional diameter, which is D2. The maximum cross-sectional diameter of the spiral scraper is D1, where D1 ≤ D2, so that the depth of each segment of the spiral groove gradually increases.

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0026] See appendix Figure 1 -Appendix Figure 10 A novel vacuum cleaner includes a body 1, a vacuuming component (not shown in the figure), a roller brush component 3, and a locking component 4. A handle 2 can be optionally installed on the top of the body 1. The vacuuming component is installed inside either the body 1 or the handle 2. The bottom of the body 1 has an suction port 11 connecting the vacuuming component to the outside. The roller brush component 3 is located beside the suction port 11 and includes a linkage cylinder 31 and a roller brush body 32. The linkage cylinder 31 is rotatably mounted on the bottom of the body 1. The roller brush body 32 is hollow and can be fitted onto or detached from the linkage cylinder 31. The locking component 4 includes a separating sleeve 41, a locking rod 42, and a self-locking snap fastener 43 with locked and unlocked states. The separating sleeve 41 is slidably mounted inside the linkage cylinder 31 and fixed to the self-locking snap fastener 43. The separating sleeve 41 also has an elastic strip 411 with a locking block 41k. The locking rod 42 is located inside the roller brush body 32 and has a locking slot 42k.

[0027] Specifically, when in use, pressing the self-locking buckle 43 locks the device in place. The elastic strip 411 is located inside the linkage cylinder 31 and deforms adaptively, causing the locking block 41k to engage with the locking rod 42k, thereby fixing the roller brush body 32 onto the linkage cylinder 31. At this time, by holding the handle 2 and moving the machine body 1, the roller brush body 32 and the linkage cylinder 31 can be rotated by the friction of the ground. At the same time, the dust collection component is activated, which can suck the generated dust into the machine body 1 or the handle 2 to achieve cleaning.

[0028] When it is necessary to disassemble the roller brush body 32, push the roller brush body 32 to drive the locking rod 42 to press the separation sleeve 41 to move, thereby driving the self-locking buckle 43 to switch from the locked state to the unlocked state. Then push the roller brush body 32 to drive the locking rod 42 to move outward. During this process, the elastic strip 411 protrudes out of the linkage cylinder 31 under the action of the self-locking buckle 43 and returns to its original state, so that the locking block 41k disengages from the locking rod 42k, thereby releasing the restriction of the separation sleeve 41 on the locking rod 42. At this time, the roller brush body 32 can be easily removed from the linkage cylinder 31 for easy cleaning and maintenance of the roller brush body 32 separately.

[0029] When the roller brush body 32 needs to be reinstalled, the roller brush body 32 is coaxially sleeved on the linkage cylinder 31. Then, the roller brush body 32 is pushed to drive the locking rod 42 to move inward until the locking rod 42 squeezes the separation sleeve 41 to move again. The elastic strip 411 will re-enter the linkage cylinder 31 and deform adaptively, so that the locking block 41k is inserted into the locking rod 42k, thus fixing the roller brush body 32 to the linkage cylinder 31.

[0030] In summary, this utility model supports the roller brush body 32 by designing a linkage cylinder 31 installed on the body 1, which can prevent the roller brush body 32 from becoming loose or directly detaching from the body 1, thereby improving the stability of the roller brush body 32 and extending its service life. By setting a locking component 4 to connect the roller brush body 32 and the linkage cylinder 31, users can easily disassemble and assemble the roller brush body 32 by gently pushing it, improving operational convenience and user experience. Therefore, this solution can solve the problems of difficult disassembly and assembly of the roller brush body 32, poor user experience, unstable installation, and short service life of the roller brush body 32 in existing vacuum cleaners.

[0031] See appendix Figure 5 -Appendix Figure 6 and attached Figure 10 -Appendix Figure 15 The press-locking buckle 43, also known as a self-spring-loaded buckle or "push-push" buckle, is commonly used in SD card sockets or ballpoint pen caps. It locks and unlocks by pressing twice (once to lock during insertion and again to eject), and is an existing structure. Since there are many types of press-locking buckles 43, this invention does not limit the specific type. For ease of understanding, in this embodiment, the press-locking buckle 43 includes a buckle plate 431, a steel wire 432, and a spring 433. The buckle plate 431 is fixed to the separating sleeve 41 and has a curved groove 4310. The first end of the steel wire 432 is oscillatingly mounted on the linkage cylinder 31, and the tail end of the steel wire 432 can slide in conjunction with the curved groove 4310. The spring 433 is located inside the linkage cylinder 31 and abuts against the separating sleeve 41 and the inner wall of the linkage cylinder 31.

[0032] Specifically, when the roller brush body 32 is pushed for the first time to move the locking rod 42 to press the separating sleeve 41, the tail end of the steel wire 432 will slide along the curved slide groove 4310 until the separating sleeve 41 is completely pushed into the linkage cylinder 31. Then, the tail end of the steel wire 432 will engage with the corner of the curved slide groove 4310 to restrict the movement of the separating sleeve 41. At this time, pressing the self-locking buckle 43 will lock it in the locked state. The spring 433 will deform and store energy. The locking block 41k on the elastic strip 411 will tightly engage with the locking slot 42k on the locking rod 42, thereby locking the roller brush body 32 onto the linkage cylinder 31.

[0033] When the roller brush body 32 is pushed again to drive the locking rod 42 to press the separating sleeve 41 to move, the tail end of the steel wire 432 will disengage from the corner of the curved slide groove 4310 and continue to move along the curved slide groove 4310 until the tail end of the steel wire 432 is completely removed from the curved slide groove 4310, thus releasing the restriction on the separating sleeve 41. At this time, pressing the self-locking buckle 43 switches to the unlocked state, and the spring 433 releases its energy and restores itself, pushing the elastic strip 411 of the separating sleeve 41 out of the linkage cylinder 31. After the elastic strip 411 is released from the restriction of the linkage cylinder 31, it resets itself, thereby causing the locking block 41k to disengage from the locking rod 42k, thus releasing the restriction on the roller brush body 32.

[0034] Therefore, in this embodiment, by pushing the roller brush body 32 a second time to drive the locking rod 42 to move, the buckle plate 431, the steel wire 432 and the spring 433 can cooperate with each other to achieve the state switching of the self-locking buckle 43.

[0035] See appendix Figure 5 -Appendix Figure 6 Appendix Figure 10 -Appendix Figure 12 and attached Figure 17 -Appendix Figure 18 The structure that drives the locking rod 42 by pushing the roller brush body 32 requires a certain amount of space to move the assembled roller brush body 32, which will affect the stability of the roller brush body 32. In addition, the roller brush body 32 is easily contaminated with dirt when the user is assembling and disassembling it, which will affect the user experience. To solve this problem, in this utility model, the tail end of the roller brush body 32 is far away from the linkage cylinder 31. The locking component 4 also includes a button 44. The button 44 is installed at the tail end of the roller brush body 32 and fixed to the locking rod 42. The button 44 has a moving stroke and can be reset by itself.

[0036] Specifically, under normal circumstances, button 44 is in the initial position. When the user presses button 44, it will cause the locking rod 42 to move inward and squeeze the separation sleeve 41. When the user releases button 44, button 44 will automatically reset and cause the locking rod 42 to move outward. With this structural design, the roller brush body 32 does not need to reserve space for movement after assembly, which improves the installation stability of the roller brush body 32. At the same time, it can also prevent the user from getting stains on the roller brush body 32 when disassembling and assembling the roller brush body 32, thus improving the user experience.

[0037] It should be noted that the button 44 with a travel range and self-resetting capability can be an elastic rubber button 44 or a mechanical button 44 supported by an elastic element, etc. Since there are various types of buttons 44 with corresponding functions and they are quite common in the mechanical field, this utility model does not limit them. For ease of understanding, in this embodiment, the button 44 uses an elastic film so that it can deform when pressed, thereby driving the locking rod 42 to move and squeeze the separation sleeve 41. After the pressure is stopped, the button 44 releases energy and restores its original state, thereby driving the locking rod 42 to reset.

[0038] Furthermore, button 44 is mounted on a snap-fit ​​block 440, which is fixed to the tail end of the roller brush body 31 by a snap-fit ​​mechanism.

[0039] See appendix Figure 11 -Appendix Figure 15Multiple elastic strips 411 are arranged in a circumferential array on the separating sleeve 41. After entering the linkage cylinder 31, the multiple elastic strips 411 deform synchronously and move closer to each other, so that multiple locking blocks 41k can be inserted into the locking slots 42k of the locking rod 42 at the same time. This design allows the separating sleeve 41 to apply uniform force to the periphery of the locking slots 42k of the locking rod 42, and can connect the locking rod 42 more stably, thereby preventing the roller brush body 32 from shaking or detaching from the linkage body during operation, further improving the stability and user experience.

[0040] See appendix Figure 16 -Appendix Figure 19 The brush body 32 has its head end close to the linkage cylinder 31 and its tail end away from the linkage cylinder 31. A protruding spiral scraper 321 is arranged on the outer wall of the brush body 32. The spiral scraper 321 starts at the head end of the brush body 32 and gradually contracts along the tail end, so that the cross-sectional diameter of each segment of the spiral scraper 321 gradually decreases. A fluff layer 322 is also provided on the brush body 32. The fluff layer 322 completely fills the outer wall of the brush body 32 and avoids the spiral scraper 321, forming a spiral groove 320 on the brush body 32. Each segment of the fluff layer 322 has the same cross-sectional diameter, with a diameter of D2. The maximum cross-sectional diameter of the spiral scraper 321 is D1, where D1 ≤ D2, so that the depth of each segment of the spiral groove 320 gradually increases.

[0041] Specifically, under this structural design, the spiral scraper 321 has varying heights. When the roller brush 32 contacts the ground and rotates, the hair, fibers, and other filamentous debris wrapped around the roller brush 32 will rotate synchronously under the action of the spiral scraper 321. Since the part of the spiral scraper 321 corresponding to the head end of the roller brush 32 is higher than the part of the spiral scraper 321 corresponding to the tail end of the roller brush 32, the spiral scraper 321 near the tail end of the roller brush 32 gradually moves away from the ground. This causes the filamentous debris to move towards the tail end of the roller brush 32 and detach from the roller brush 32, thus preventing the filamentous debris from continuing to wrap around and preventing the roller brush 32 from properly rubbing the ground. When the roller brush 32 contacts the ground, the pile layer 322 will undergo slight deformation due to the pressure of the ground, so that the pile layer 322 as a whole and the spiral scraper 321 protrude from the highest part of the roller brush 32 and simultaneously contact the ground. In this case, if the roller brush 32 rotates, the pile layer 322 is mainly responsible for winding and adsorbing filamentous debris, while the spiral scraper 321 is mainly responsible for squeezing and pushing the filamentous debris. Under the action of the spiral groove 320 formed by the pile layer 322 and the spiral scraper 321, the filamentous debris can be better rolled up until it is rolled up to the tail end or both ends of the roller brush 32, and the filamentous debris is detached from the pile layer 322 and falls off.

[0042] In summary, the spiral groove 320, in combination with the pile layer 322, forms a spiral groove 320 structure that can quickly and thoroughly roll up and remove filamentous debris from the brush body 32, thereby improving the anti-tangling effect and ensuring the cleaning ability of the brush body 32.

[0043] See appendix Figure 16 -Appendix Figure 19 The highest point of the protruding part of the spiral scraper 321 has an inclination angle α with the outer side wall of the roller brush body 32, where 0°<α≤20°.

[0044] Specifically, within this angle range, it can ensure that the spiral scraper 321 can properly rub against loose dirt and dust on the ground, and also ensure that the spiral scraper 321 can smoothly roll up filamentous debris. In addition, in actual use, the tilt angle α will increase or decrease with the change of the length of the roller brush body 32, but it is generally within 20°. In the standard length of the roller brush body 32, the optimal tilt angle α of the spiral scraper 321 is 3°, that is, the tilt angle α=3° is the best solution.

[0045] See appendix Figure 16 -Appendix Figure 19 The roller brush body 32 and the spiral scraper 321 are integrally formed; this design not only facilitates processing and production and ensures the strength of the spiral scraper 321, but also allows the spiral scraper 321 to better transmit the force it receives to the roller brush body 32 and distribute it evenly, thereby improving the structural stability and service life of the spiral scraper 321.

[0046] See appendix Figure 16 -Appendix Figure 19 Multiple spiral scraper blades 321 are arranged in a circumferential array on the outer wall of the roller brush body 32, and two spiral scraper blades 321 are arranged to form a receiving groove 3210. Multiple pile layers 322 are arranged and filled into multiple receiving grooves 3210. This design can increase the contact between the spiral scraper blades 321 and the pile layer 322 and the ground, thereby further improving the ability to roll up filamentous debris. At the same time, the design of multiple spiral scraper blades 321 can also make the force on the periphery of the roller brush body 32 more uniform, so as to extend its service life.

[0047] See appendix Figure 2 -Appendix Figure 7 The bottom of the body 1 is provided with a rotating cavity 12. A notch 120 for connecting to the outside is opened on one side of the rotating cavity 12. A fixed seat 13 is provided inside the rotating cavity 12. The suction port 11 is formed on the inner wall of the rotating cavity 12. The roller brush assembly 3 is set inside the rotating cavity 12. The linkage cylinder 31 is rotatably connected to the fixed seat 13. The roller brush body 32 can enter and exit the rotating cavity 12 through the notch 120 and be fitted or detached from the linkage cylinder 31.

[0048] Specifically, when using the machine, place the machine body 1 on the ground and make the roller brush 32 contact the ground. Moving the machine body 1 will cause the roller brush 32 to rotate and rub the ground by relying on the friction applied by the ground. At the same time, the vacuuming component is activated to generate negative air pressure, which can draw loose dust into the machine body 1 through the suction port 11 to complete the cleaning operation.

[0049] When it is necessary to disassemble the roller brush body 32, push the roller brush body 32 to drive the locking component 4 to switch to the unlocked state to release the restriction on the roller brush body 32, and then move the roller brush body 32 outward along the notch 120; when it is necessary to install the roller brush body 32, move the roller brush body 32 inward along the notch 120 to make the locking component 4 switch to the locked state, and then fix the roller brush body 32 back onto the linkage cylinder 31.

[0050] See appendix Figure 2 -Appendix Figure 7 Both sides of the rotating cavity 12 have openings 120 for connecting to the outside. The fixed seat 13 is located in the middle of the rotating cavity 12. The suction port 11 is formed on the inner wall of the rotating cavity 12 and is set corresponding to the fixed seat 13. There are two sets of roller brush assemblies 3, which are symmetrically arranged in the rotating cavity 12 with the fixed seat 13 as the center. Both linkage cylinders 31 are rotatably connected to the fixed seat 13. The two roller brush bodies 32 can enter and exit the rotating cavity 12 through the two openings 120 and be respectively fitted onto or detached from the two linkage cylinders 31. There are two sets of locking components 4, which correspond one to one of the two sets of roller brush assemblies 3. With this design, the contact area with the ground can be increased by increasing the number of roller brush assemblies 3. The suction port 11 is set in the middle of the two roller brush bodies 32, which works on the bottom surface of the two roller brush bodies 32 in contact with the dust collection component at the same time, effectively improving the work efficiency.

[0051] See appendix Figure 2 -Appendix Figure 7 In addition to relying on friction with the ground to drive the two roller brushes 32 to rotate, the two roller brushes 32 can also be driven by an electric structure. For ease of understanding, the linkage cylinder 31 is rotatably connected to the fixed base 13 or does not contact the fixed base 13. A dual-axis motor 14 is installed on the fixed base 13, and the two output shafts of the dual-axis motor 14 are coaxially connected to the two linkage cylinders 31 respectively.

[0052] Specifically, when using the machine, place the machine body 1 on the ground and make the two roller brushes 32 contact the ground. Then, start the dual-axis motor 14 to drive the two roller brushes 32 to rotate in an involute motion, which can move the machine body 1 and save physical effort. At the same time, the dual-axis motor 14 can also prevent the two roller brushes 32 from rotating abnormally, thus improving the stability of use.

[0053] See appendix Figure 2 -Appendix Figure 7The bottom of the machine body 1 is symmetrically provided with two rotating cavities 12 centered on the adsorption port 11, and each rotating cavity 12 is provided with a fixed seat 13; there are four sets of roller brush assemblies 3, with two sets of roller brush assemblies 3 installed in one of the rotating cavities 12 and the other two sets of roller brush assemblies 3 installed in the other rotating cavity 12; there are two dual-axis motors 14, which are installed on the two fixed seats 13 respectively; this design can not only make the front and rear sides of the machine body 1 evenly stressed, ensuring a more balanced overall structure, but also further improve the working efficiency by increasing the number of roller brush assemblies 3.

[0054] It should be noted that the dust collection component in the above embodiments is usually a dust collection fan, which is widely used in vacuum cleaners and belongs to the existing structure. Therefore, the specific components and working principle of the dust collection component are not described in detail in this utility model. As for the power supply of the dust collection component and the dual-axis motor 14, a battery (not shown in the figure) can be installed inside the body 1 for power supply, or an external power supply can be used directly. This utility model does not limit this. On the other hand, the dual-axis motor 14 can be a servo motor to facilitate program control, or a planetary motor with reduced gearbox can be used. Since there are many types of motors, this utility model does not limit this either.

[0055] See appendix Figure 2 -Appendix Figure 7 The bottom of the body 1 is also equipped with rollers 15, which are located between the two rotating cavities 12. The design of the rollers 15 can further improve the mobility of the body 1.

[0056] See appendix Figure 2 -Appendix Figure 7 The bottom of the body 1 is also equipped with a cotton strip 16, which is located between the two rotating chambers 12. The design of the cotton strip 16 can isolate the roller brush components 3 in the two rotating chambers 12, so as to avoid interference and improve the cleaning effect.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
