Description

Technical Field

[0001] This utility model belongs to the field of broom technology, and in particular relates to an efficient broom with an adjustable angle. Background Technology

[0002] As one of the most basic cleaning tools, brooms are widely used in daily cleaning in various environments such as homes, offices, businesses, and industries. Their core function is to remove dust and debris through effective contact between the bristles and the ground. However, actual cleaning environments are often complex and varied. For example, it may be necessary to clean under low furniture, narrow gaps, corners, or floors of different materials or slopes. In these scenarios, users often need to adjust the angle of the broom handle or change the overall length of the broom to improve cleaning efficiency, reduce labor intensity, and achieve a more thorough cleaning effect.

[0003] Existing brooms have significant limitations in practical use. On the one hand, because the brush head and handle adopt a fixed angle structure, when cleaning corners, the brush head cannot adjust its tilt according to the angle of the contact surface, which easily leads to the problem of the brush not adhering tightly to the surface to be cleaned, resulting in dust and debris residue in the corners. On the other hand, the handle length is fixed and there is no telescopic adjustment mechanism. Due to differences in user height or different cleaning scenarios requiring different handle lengths, the fixed handle length can easily increase the labor intensity of users due to unnatural postures such as bending over or tiptoeing, and may even affect cleaning efficiency. The core reason for these defects is that the existing structure lacks a flexible angle adjustment plate structure and length adjustment mechanism, which cannot adapt to diverse cleaning needs.

[0004] To address these issues, we offer an adjustable-angle, high-efficiency broom. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable-angle, high-efficiency broom. By combining the angle adjustment mechanism and the telescopic mechanism, it solves the problems of the brush not fitting tightly to the surface to be cleaned and the fixed length of the broom not being able to extend or retract in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an adjustable-angle, high-efficiency broom, comprising a base, an angle adjustment mechanism fixedly connected to the top of the base, and a telescopic mechanism fixedly connected to the top of the angle adjustment mechanism; the angle adjustment mechanism includes a bracket located above the base, a first toothed disc fixedly connected to the inner wall of the bracket, a rotating rod threadedly connected to the surface of the bracket, one end of the rotating rod penetrating the inner wall of the bracket and movably connected to a second toothed disc via a bearing, the first toothed disc and the second toothed disc meshing together, the bottom of the second toothed disc fixedly connected to the base; the telescopic mechanism includes a vertical rod, the bottom end of the vertical rod fixedly connected to the bracket, a telescopic rod slidably connected to the inner wall of the vertical rod, a fastening sleeve fixedly connected to the surface of the vertical rod, an eccentric wheel movably connected to the inner wall of the fastening sleeve, and a baffle fixedly connected to the inner wall of the fastening sleeve, one side of the baffle penetrating through... The device includes a squeezing block. The inner wall of the fastening sleeve has a groove for engaging the squeezing block. One side of the squeezing block extends through the groove, contacting an eccentric wheel on one side and a telescopic rod on the other. A wrench is fixedly connected to the surface of the eccentric wheel. Rotating the rod causes the second toothed disc to move closer to or further away from the first toothed disc. When the toothed discs are engaged, the angle of the base and brush is fixed; when disengaged, the angle can be adjusted by rotation. The telescopic mechanism rotates the eccentric wheel by turning the wrench. The squeezing block, under the action of the eccentric wheel, presses against the telescopic rod to fix its length. Turning the wrench in the opposite direction adjusts the length of the telescopic rod. The angle adjustment design of the toothed disc engagement allows for precise fixing of any cleaning angle, adapting to special areas such as corners and under furniture. The telescopic structure with eccentric wheel squeezing quickly locks the length, making operation effortless and securely fixed, preventing the telescopic rod from slipping during use, and catering to the needs of users of different heights and cleaning scenarios.

[0008] The present invention is further configured such that a fixing plate is fixedly connected to the surface of the fastening sleeve, and a first spring is fixedly connected between the fixing plate and the wrench. The fixing plate connects the fastening sleeve and the first spring, and one end of the first spring is connected to the wrench. After the wrench is released, the wrench is pulled to reset, so that the eccentric wheel maintains the compressive force on the extrusion block. The automatic reset function of the spring eliminates the manual locking step. After the wrench is released, the telescopic rod is automatically fixed. The continuous elastic force ensures that the extrusion block is stably pressed against the telescopic rod, avoiding the length loosening caused by vibration during use.

[0009] The present invention is further configured such that a brush is fixedly connected to the bottom of the base, a support plate is fixedly connected to the surface of the base, a foot pedal is provided above the support plate, a second spring is fixedly connected between the foot pedal and the support plate, a push rod is fixedly connected to the bottom of the foot pedal, and the other end of the push rod passes through the support plate and is fixedly connected to a cleaning plate used with the brush. The foot pedal is connected to the support plate through the second spring. When stepped on, it drives the push rod and the cleaning plate to move down, scraping off hair and other debris wrapped around the surface of the brush. After being released, the spring drives the cleaning plate to return to its original position. The foot-operated cleaning design eliminates the need to manually clean the brush, avoids hand contact with dirt, and the spring's return ensures that the cleaning plate does not affect normal cleaning.

[0010] The present invention is further configured such that a limiting block is fixedly connected to the back of the foot pedal, and a limiting groove is provided on the surface of the base to cooperate with the limiting block. The limiting block is slidably connected to the limiting groove. The limiting block slides along the limiting groove on the surface of the base to constrain the movement trajectory of the foot pedal, prevent it from deviating to the left or right, ensure that the cleaning plate moves vertically downward, accurately fits the surface of the brush, avoids scratching the brush fibers, and reduces foot pedal shaking.

[0011] The present invention is further configured such that strong magnets are fixedly connected to both sides of the bottom of the base, and a handle is fixedly connected to the top of the telescopic rod. The handle has a through hole on its surface. The strong magnets at the bottom of the base attract metal waste from the ground, the handle is easy to grip, and the through hole is used for hanging and storage.

[0012] The present invention is further configured such that a mounting plate is fixedly connected to the top of the support plate by bolts, and the back of the mounting plate is fixedly connected to the surface of the base by bolts. The mounting plate connects the support plate and the base by bolts, fixing the position of the pedal, push rod, etc., to prevent loosening when stepping on it. The detachable design makes it easy to replace the worn cleaning plate or support plate separately.

[0013] The present invention is further configured such that a handwheel is fixedly connected to the surface of the rotating rod, and the surface of the handwheel is provided with anti-slip teeth. The handwheel on the surface of the rotating rod increases the gripping area, and the anti-slip teeth increase the friction, making it easier to rotate the rotating rod to adjust the meshing state of the gear plate.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model uses a handwheel to rotate a rotating rod to control the engagement and disengagement of the second and first toothed discs. It is simple and labor-saving to operate. During adjustment, the second toothed disc can be rotated to drive the base and brush to rotate flexibly to the required angle, adapting to different cleaning scenarios. After adjustment, rotating the rotating rod in the opposite direction can make the two toothed discs mesh tightly, firmly fix the angle, avoid angle deviation due to force during cleaning, ensure the stability of the cleaning direction, and improve cleaning efficiency.

[0016] 2. This utility model allows for control of the pressure of the eccentric wheel on the extrusion block by simply turning the wrench, quickly switching between tight and loose telescopic rods. During adjustment, the telescopic rod can be freely pulled to adjust to a length suitable for the user's height or cleaning range, making it highly adaptable. After releasing the wrench, the eccentric wheel automatically resets and presses the telescopic rod to fix it securely, ensuring that it is not easy to slip and guaranteeing a stable broom length during use, thus reducing the burden of operation.

Detailed Implementation

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-6This utility model relates to an adjustable-angle, high-efficiency broom, comprising a base 1, an angle adjustment mechanism 2 fixedly connected to the top of the base 1, and a telescopic mechanism 3 fixedly connected to the top of the angle adjustment mechanism 2; the angle adjustment mechanism 2 includes a bracket 21 located above the base 1, a first gear 22 fixedly connected to the inner wall of the bracket 21, a rotating rod 23 threadedly connected to the surface of the bracket 21, one end of the rotating rod 23 penetrating the inner wall of the bracket 21 and movably connected to a second gear 24 via a bearing, the first gear 22 and the second gear 24 meshing together, and the bottom of the second gear 24 fixedly connected to the base 1; the telescopic mechanism... 3 includes a vertical rod 31, the bottom end of which is fixedly connected to the bracket 21. A telescopic rod 32 is slidably connected to the inner wall of the vertical rod 31. A fastening sleeve 33 is fixedly connected to the surface of the vertical rod 31. An eccentric wheel 34 is movably connected to the inner wall of the fastening sleeve 33. A baffle 35 is fixedly connected to the inner wall of the fastening sleeve 33. A pressing block 36 is connected through one side of the baffle 35. A groove is opened on the inner wall of the fastening sleeve 33 to cooperate with the pressing block 36. One side of the pressing block 36 extends through the groove. One side of the pressing block 36 contacts the eccentric wheel 34. The other side of the pressing block 36 contacts the telescopic rod 32. A wrench 37 is fixedly connected to the surface of the eccentric wheel 34.

[0028] Specifically: The rotating rod 23 drives the second toothed disc 24 to move closer to or further away from the first toothed disc 22. When the toothed discs are engaged, the angle of the base 1 and the brush 5 is fixed. When they are separated, the angle can be adjusted by rotation. The telescopic mechanism 3 drives the eccentric wheel 34 to rotate by pulling the lever 37. The pressing block 36 presses against the telescopic rod 32 under the action of the eccentric wheel 34 to fix the length. The reverse lever can adjust the length of the telescopic rod 32. The angle adjustment design of the toothed disc engagement can accurately fix any cleaning angle, adapting to special areas such as corners and the bottom of furniture. The telescopic structure pressed by the eccentric wheel 34 can quickly lock the length, making operation labor-saving and firmly fixed, preventing the telescopic rod 32 from sliding during use, and taking into account the needs of users of different heights and cleaning scenarios.

[0029] Example 2

[0030] Please see Figure 1-6Based on Embodiment 1, a fixing plate is fixedly connected to the surface of the fastening sleeve 33, and a first spring 4 is fixedly connected between the fixing plate and the wrench 37. A brush 5 is fixedly connected to the bottom of the base 1, and a support plate is fixedly connected to the surface of the base 1. A foot pedal 6 is provided above the support plate, and a second spring 7 is fixedly connected between the foot pedal 6 and the support plate. A push rod 8 is fixedly connected to the bottom of the foot pedal 6, and the other end of the push rod 8 passes through the support plate and is fixedly connected to a cleaning plate 9 used in conjunction with the brush 5. A limit block is fixedly connected to the back of the foot pedal 6, and a limit groove is provided on the surface of the base 1 to cooperate with the limit block. The limit block and the limit groove are slidably connected. Strong magnets are fixedly connected to both sides of the bottom of the base 1. A handle is fixedly connected to the top of the telescopic rod 32, and a through hole is provided on the surface of the handle. A mounting plate is fixedly connected to the top of the support plate by bolts, and the back of the mounting plate is fixedly connected to the surface of the base 1 by bolts. A handwheel is fixedly connected to the surface of the rotating rod 23, and the surface of the handwheel is provided with anti-slip teeth.

[0031] Specifically: The fixing plate connects the fastening sleeve 33 to the first spring 4. One end of the first spring 4 is connected to the wrench 37. After releasing the wrench 37, pulling the wrench 37 resets the spring, maintaining the pressure of the eccentric wheel 34 on the pressing block 36. The automatic spring reset function eliminates the need for manual locking. Releasing the wrench 37 automatically fixes the telescopic rod 32. The continuous elasticity ensures that the pressing block 36 stably holds the telescopic rod 32, preventing loosening due to vibration during use. The foot pedal 6 is connected to the support plate via the second spring 7. When stepped on, it moves the push rod 8 and the cleaning plate 9 downwards, scraping away hair and other debris entangled on the surface of the brush 5. After releasing the pedal, the spring resets the cleaning plate 9. The foot-operated cleaning design eliminates the need for manual cleaning of the brush 5, avoiding hand contact with dirt. The spring reset ensures that the cleaning plate 9 does not affect normal cleaning. The limit block slides along the limit groove on the surface of the base 1, constraining the movement trajectory of the pedal 6 and preventing it from deviating to the left or right. This ensures that the cleaning plate 9 moves vertically downward and precisely fits the surface of the brush 5, avoiding scratching the fibers of the brush 5 and reducing the shaking of the pedal 6. A strong magnet at the bottom of the base 1 attracts metal debris from the ground. The handle is easy to grip, and the through hole is used for hanging and storage. The mounting plate is connected to the support plate and the base 1 by bolts, fixing the position of the pedal 6, push rod 8, etc., to prevent loosening when stepped on. The detachable design makes it easy to replace the worn cleaning plate 9 or support plate individually. The handwheel on the surface of the rotating rod 23 increases the gripping area, and the anti-slip teeth increase friction, making it easy to rotate the rotating rod 23 to adjust the meshing state of the toothed disc.

[0032] The working principle of this utility model is as follows: When using this adjustable-angle high-efficiency broom, the angle can be adjusted according to the cleaning needs. By rotating the rotating rod 23 with the handwheel, the rotating rod 23 can move outward or inward, causing the second toothed disc 24 to move away from or towards the first toothed disc 22. When rotating the rotating rod 23 causes the second toothed disc 24 to move away from the first toothed disc 22, rotating the second toothed disc 24 causes the base 1 and brush 5 to rotate to the desired angle. Reversing the rotation of the rotating rod 23 causes the rotating rod 23 to move inward, causing the second toothed disc 24 to move closer to the first toothed disc 22, so that the second toothed disc 24 and the first toothed disc 22 are tightly engaged, which can fix the current angle and prevent the angle from shifting during cleaning. If it is necessary to adjust the broom length, the wrench 37 is pulled, and the wrench 37 drives the eccentric wheel 34 to rotate, reducing the squeezing force of the eccentric wheel 34 on the squeezing block 36. When the length is small, the telescopic rod 32 can be pulled and slid within the vertical rod 31 to adjust to a suitable length. After releasing the wrench 37, the first spring 4 between the fixed plate and the wrench 37 will pull the wrench 37 back to its original position. The eccentric wheel 34 will re-press the squeezing block 36, and the squeezing block 36 will press against the telescopic rod 32 to fix it in place, preventing the telescopic rod 32 from sliding during use. During the cleaning process, if hair or other debris gets tangled on the brush 5, step on the pedal 6. The pedal 6 will compress the second spring 7 and drive the push rod 8 to move down. The push rod 8 will drive the cleaning plate 9 to move down and scrape off the debris tangled on the surface of the brush 5. Release the pedal 6, and the second spring 7 will return to its original position, driving the pedal 6 and the cleaning plate 9 to move up. This will not affect normal cleaning. The strong magnet at the bottom of the base 1 can attract metal debris such as iron nails and iron pieces from the ground, improving the cleaning effect. The handle is easy to grip, and the through hole can be used for hanging and storage.
