Description

Technical Field

[0001] This utility model relates to the technical field of cleaning equipment, and in particular to a cleaning device. Background Technology

[0002] Cleaning equipment currently on the market, especially vacuum cleaners, typically needs to be stored upright after use to save space. To ensure the stability of the equipment in an upright position, existing technologies generally employ an upright locking structure to prevent accidental tipping.

[0003] Most existing upright locking structures use a spring locking mechanism, which typically includes multiple components such as a spring, a locking element, and a release button. The specific working principle is as follows: when the cleaning equipment needs to be stored upright, the spring's elastic force pushes the locking element into the locking position, locking the body assembly and the floor brush assembly; when needed, the user presses the release button, overcoming the spring's elastic force and disengaging the locking element from the locked position, thus releasing the lock.

[0004] However, existing technologies have the following shortcomings:

[0005] 1. Complex structure: The spring locking mechanism requires the cooperation of multiple parts, including spring, locking component, guide component, release button, etc., which makes the structure complex and the assembly process cumbersome.

[0006] 2. High cost: The manufacturing and assembly of multiple parts increases production costs, especially for precision parts such as springs.

[0007] 3. Reliability issues: Springs are prone to fatigue failure after long-term use, resulting in insufficient locking force or complete failure; the cooperation of multiple components increases the number of failure points and reduces overall reliability.

[0008] 4. Difficult to maintain: The internal structure of the spring locking mechanism is complex. Once a malfunction occurs, repair and replacement are difficult and maintenance costs are high.

[0009] 5. Inconvenient operation: Users need to press the release button accurately to unlock, which is not intuitive or convenient. Utility Model Content

[0010] (a) Technical problems to be solved

[0011] The technical problem to be solved by this utility model is to provide a cleaning device that achieves the upright locking function of the cleaning device through the cooperation of the first locking member and the second locking member, avoiding complex mechanical locking mechanisms. After use, the user only needs to rotate the body component to the upright position to automatically lock it, which is simple to operate. The interference fit locking method ensures the stability of the upright state and avoids accidental tipping, solving the stability problem of the cleaning device when stored. It also solves the technical problems of complex structure, high cost and low reliability of the spring locking mechanism in the prior art.

[0012] (II) Technical Solution

[0013] The solution adopted by this utility model to solve the above-mentioned technical problems is a cleaning device, including...

[0014] The floor brush assembly is equipped with cleaning components for cleaning the surface to be cleaned;

[0015] The body assembly is rotatably connected to the end of the floor brush assembly that is away from the cleaning component;

[0016] A first locking element is provided on the floor brush assembly;

[0017] The second locking element is located at the part where the body assembly and the floor brush assembly mate;

[0018] When the first locking member and the second locking member cooperate to lock, they can prevent the body assembly from rotating relative to the floor brush assembly when the body assembly is in an upright position relative to the floor brush assembly.

[0019] Specifically, when the body assembly rotates relative to the floor brush assembly to an upright position, the first locking member and the second locking member form an interference fit to prevent the body assembly from rotating.

[0020] In some embodiments, the cleaning device is a vacuum cleaner; after use, the vacuum cleaner is locked in an upright position by the cooperation of the first locking member and the second locking member; during cleaning, normal use is achieved by unlocking the first locking member and the second locking member.

[0021] In some embodiments, the first locking member is detachably attached to the top of the floor brush assembly.

[0022] By adopting the above solution, the upright locking function of the cleaning equipment is realized through the cooperation of the first locking component and the second locking component, avoiding complex mechanical locking mechanisms. After use, the user only needs to rotate the body component to the upright position to automatically lock it, which is simple to operate. The interference fit locking method ensures the stability of the upright state, avoids accidental tipping, and solves the stability problem when storing the cleaning equipment.

[0023] In some embodiments, the first locking member includes a locking cavity disposed on the floor brush assembly; the second locking member includes a locking protrusion disposed on the body assembly, the locking protrusion being made of a material with elastic deformation capability.

[0024] In some embodiments, the locking protrusion is made of plastic, which is both elastic and wear-resistant, thus extending its service life.

[0025] The above solution uses a material with elastic deformation capability to make the locking protrusion, and utilizes the inherent properties of the material to achieve the locking function. Compared with the traditional spring locking mechanism, it reduces the number of parts and manufacturing processes, and the self-recovery properties of the elastic material ensure the long-term stability of the locking mechanism.

[0026] In some embodiments, the end of the locking cavity facing the body assembly is an open end.

[0027] The above design facilitates the insertion of the locking protrusion, improving the smoothness of the locking operation; it also facilitates cleaning and maintenance, preventing the accumulation of dirt.

[0028] In some embodiments, the locking protrusion moves rearward by its own elastic deformation, unlocking when the operating body assembly is rotated until the locking protrusion disengages from the locking cavity, and locking when the locking protrusion enters the locking cavity.

[0029] The above solution achieves automatic locking and unlocking through elastic deformation, eliminating the need for manual intervention and enabling an intuitive "rotate to lock" operation. The rapid deformation and recovery characteristics of the elastic material ensure timely response of the locking operation, while the elastic deformation also provides cushioning, reducing mechanical impact (lowering noise and wear), and making the rotation operation smoother, ensuring long-term reliability.

[0030] In some embodiments, the top of the locking protrusion has a first inclined end face arranged from top to bottom, and the top of the locking cavity has a second inclined end face that mates with the first inclined end face.

[0031] In some embodiments, the locking protrusion is provided with a first guide arc surface at one end of the first inclined end face near the locking cavity, and the locking cavity is provided with a second guide arc surface at the top of the open end.

[0032] The above-mentioned design, with the first and second inclined end faces working together, provides a better guiding effect and ensures the accuracy of the locking position. At the same time, the two inclined end faces increase the contact area, improve the locking stability, make the force more uniform, and avoid stress concentration. The first and second guide arc surfaces make the process of the locking protrusion entering / exiting the locking cavity smoother.

[0033] In some embodiments, the second locking member includes an annular connecting portion fitted onto the body assembly, and an extension portion formed by the annular connecting portion extending downward toward one end of the floor brush assembly, wherein the middle portion of the outer wall of the extension portion at its bottom end extends toward one end near the floor brush assembly to form the locking protrusion.

[0034] In some embodiments, the extension has protrusions at both ends, with the bottom of the protrusions slightly higher than the top of the locking protrusions; the locking cavity has support portions at both ends that can support the bottom of the protrusions.

[0035] Specifically, when the locking protrusion is locked in the locking cavity, the two support portions can engage with each other on both ends of the extension.

[0036] By adopting the above solution, the cooperation between the protrusion and the support forms an auxiliary support, which enhances the locking between the locking protrusion and the locking cavity and prevents the body components from shaking in the locked state.

[0037] In some embodiments, the body assembly includes a force-bearing fulcrum C and a rotation axis D; when the body assembly is subjected to force, the locking protrusion elastically deforms with the rotation axis D as the axis and the force-bearing fulcrum C as the fulcrum, thereby achieving locking and disengagement with the locking cavity.

[0038] The above scheme employs an elastic deformation mechanism with the rotation axis D as the axis and the force fulcrum C as the lever fulcrum. The lever principle amplifies the operating force, making unlocking easier and providing a reasonable mechanical transmission path. Precise control of locking and unlocking is achieved through mechanical principles. At the same time, the design of the force fulcrum C avoids plastic deformation and extends service life.

[0039] In some embodiments, the force-bearing fulcrum C is positioned above the locking protrusion; there are two rotating shafts D, which are positioned opposite each other at the bottom of the body assembly and opposite each other at both ends of the locking protrusion.

[0040] With the above scheme, the force fulcrum C is located above the locking protrusion, providing favorable force conditions; the design of two rotating shafts D ensures the stability and balance of rotation, the dual rotating shaft structure balances the torque, prevents unilateral wear, and the symmetrical arrangement improves rotational stability.

[0041] In some embodiments, the floor brush assembly has rotating shaft seats at both ends of the locking cavity that extend toward the body assembly. The two rotating shaft seats are provided with rotating holes opposite each other, and the two rotating shafts D respectively cooperate with the two rotating holes to realize the rotation between the body assembly and the floor brush assembly.

[0042] The above scheme provides a reliable rotational connection between the rotating shaft seat and the rotating hole; the design of the rotating shaft seat extending from both ends of the locking cavity achieves a compact structure.

[0063] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0064] like Figures 1-6 As shown, this utility model provides a cleaning device, including a floor brush assembly 100 with a cleaning component 101 for cleaning the surface to be cleaned; a body assembly 200 rotatably connected to one end of the floor brush assembly 100 away from the cleaning component 101; a first locking member 102 disposed on the floor brush assembly 100; and a second locking member 201 disposed at the part of the body assembly 200 that cooperates with the floor brush assembly 100. When the first locking member 102 and the second locking member 201 are engaged, they can prevent the body assembly 200 from rotating relative to the floor brush assembly 100 when the body assembly 200 is in an upright position relative to the floor brush assembly 100. Specifically, when the body assembly 200 rotates relative to the floor brush assembly 100 to an upright position, the first locking member 102 and the second locking member 201 form an interference fit, preventing the body assembly 200 from rotating. In some embodiments, the cleaning device is a vacuum cleaner; after use, the vacuum cleaner is locked in an upright position by the cooperation of the first locking member 102 and the second locking member 201; during cleaning, normal use is achieved by unlocking the first locking member 102 and the second locking member 201. In some embodiments, the first locking member 102 is detachably connected to the top of the floor brush assembly 100. Using the above solution, the cooperation of the first locking member 102 and the second locking member 201 achieves the upright locking function of the cleaning device, avoiding complex mechanical locking mechanisms; after use, the user only needs to rotate the body assembly 200 to the upright position for automatic locking, making operation simple; the interference fit locking method ensures the stability of the upright state, preventing accidental tipping and solving the stability problem when storing the cleaning device.

[0065] In some embodiments, the first locking member 102 includes a locking cavity 1021 disposed on the floor brush assembly 100; the second locking member 201 includes a locking protrusion 2011 disposed on the body assembly 200, the locking protrusion 2011 being made of a material with elastic deformation capability. In some embodiments, the material of the locking protrusion 2011 is a plastic material, which combines elasticity and wear resistance, extending its service life. By using the above solution, the locking protrusion 2011 is made of a material with elastic deformation capability, utilizing the inherent properties of the material to achieve the locking function. Compared with traditional spring locking mechanisms, this reduces the number of parts and manufacturing processes, and the self-restoring properties of the elastic material ensure the long-term stability of the locking mechanism. In some embodiments, the end of the locking cavity 1021 facing the body assembly 200 is an open end 1021a. Using the above solution, the open end 1021a is designed to facilitate the insertion of the locking protrusion 2011, improving the smoothness of the locking operation; it also facilitates cleaning and maintenance, preventing dirt accumulation.

[0066] In some embodiments, the locking protrusion 2011 moves rearward through its own elastic deformation. Unlocking is achieved when the body assembly 200 is rotated until the locking protrusion 2011 disengages from the locking cavity 1021, and locking is achieved when the locking protrusion 2011 enters the locking cavity 1021. Using this scheme, automatic locking and unlocking are achieved through elastic deformation, eliminating the need for manual intervention and realizing an intuitive "rotate to lock" operation. The rapid deformation and recovery characteristics of the elastic material ensure timely response of the locking operation, and the elastic deformation also provides cushioning, reducing mechanical impact (lowering noise and wear). Furthermore, the rotation operation is smoother, ensuring long-term reliability. In some embodiments, the top of the locking protrusion 2011 has a first inclined end face 2011a arranged from top to bottom, and the top of the locking cavity 1021 has a second inclined end face 1021b that mates with the first inclined end face 2011a. In some embodiments, the locking protrusion 2011 has a first guide arc surface 2011e at the end of the first inclined end face 2011a near the locking cavity 1021, and the locking cavity 1021 has a second guide arc surface 1021d at the top of the open end 1021a. With this design, the cooperative design of the first inclined end face 2011a and the second inclined end face 1021b provides better guiding effect and ensures the accuracy of the locking position. Simultaneously, the increased contact area of ​​the two inclined end faces improves locking stability, resulting in more uniform force distribution and avoiding stress concentration. The first guide arc surface 2011e and the second guide arc surface 1021d make the process of the locking protrusion 2011 entering / exiting the locking cavity 1021 smoother. In some embodiments, the second locking member 201 includes an annular connecting portion 2011b sleeved on the body assembly 200, and an extension portion 2011c extending downward from one end of the annular connecting portion 2011b toward the floor brush assembly 100. The middle portion of the outer wall of the extension portion 2011c at its bottom end extends toward the end near the floor brush assembly 100 to form the locking protrusion 2011. In some embodiments, both ends of the extension portion 2011c are provided with protrusions 2011d, the bottom end of the protrusions 2011d being slightly higher than the top end of the locking protrusion 2011; both ends of the locking cavity 1021 are provided with support portions 1021c capable of supporting the bottom end of the protrusions 2011d. Specifically, when the locking protrusion 2011 is locked in the locking cavity 1021, the two support portions 1021c can be engaged relative to each other on both ends of the extension portion 2011c. Using the above solution, the cooperation between the protrusion 2011d and the support 1021c forms an auxiliary support, which enhances the locking between the locking protrusion 2011 and the locking cavity 1021 and prevents the fuselage assembly 200 from shaking in the locked state.In some embodiments, the body assembly 200 includes a force-bearing fulcrum C202 and a rotation axis D203. When the body assembly 200 is subjected to force, the locking protrusion 2011 undergoes elastic deformation with the rotation axis D203 as the axis and the force-bearing fulcrum C202 as the fulcrum, thereby achieving locking and disengagement with the locking cavity 1021. Using the above scheme, the elastic deformation mechanism with the rotation axis D203 as the axis and the force-bearing fulcrum C202 as the lever fulcrum amplifies the operating force through the lever principle, making unlocking easier and providing a reasonable mechanical transmission path. Precise control of locking and disengagement is achieved through mechanical principles. Simultaneously, the design of the force-bearing fulcrum C202 avoids plastic deformation and extends service life. In some embodiments, the force-bearing fulcrum C202 is positioned above the locking protrusion 2011; there are two rotation axes D203, positioned opposite each other at the bottom end of the body assembly 200 and opposite each other at both ends of the locking protrusion 2011. With the above scheme, the force fulcrum C202 is located above the locking protrusion 2011, providing favorable force conditions; the design of the two rotating shafts D203 ensures the stability and balance of rotation, the dual rotating shaft structure balances the torque, prevents unilateral wear, and the symmetrical arrangement improves rotational stability.

[0067] In some embodiments, the floor brush assembly 100 has rotating shaft seats 103 extending from both ends of the locking cavity 1021 toward the body assembly 200. Two rotating shaft seats 103 are provided with opposing rotating holes 1031, and two rotating shafts D203 respectively cooperate with the two rotating holes 1031 to achieve rotation between the body assembly 200 and the floor brush assembly 100. With this design, the cooperation between the rotating shaft seats 103 and the rotating holes 1031 provides a reliable rotational connection; the design of the rotating shaft seats 103 extending from both ends of the locking cavity 1021 achieves a compact structure.

[0069] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
