Description

Technical Field

[0001] This utility model relates to the field of floor brush technology, specifically a vacuum cleaner floor brush based on adaptive adjustment of the scraper blades in the direction of movement. Background Technology

[0002] When using a vacuum cleaner's floor brush, for example, when the brush is moving forward, if the air intake area between the brush and the floor is too large (air intake from all four sides outside the suction port), the suction power at the suction port will be insufficient, affecting the vacuuming efficiency. Existing floor brushes improve this problem by incorporating scraper strips at the bottom of the brush and outside the suction port. During use, the scraper strips scrape dust and other particles off the floor, allowing them to be sucked into the suction port. However, when the brush moves in different directions, the scraper strips may obstruct large dust particles, preventing them from being sucked into the suction port and affecting vacuuming efficiency. To address this issue, some floor brushes use a lifting, movable scraper strip design; however, this is complex, increases cost, and is not very user-friendly. Utility Model Content

[0003] The purpose of this utility model is to solve the problems of existing floor brushes having complex scraper strip structures at the bottom, high costs, and difficulty in making quick structural adjustments based on different movement directions and usage methods, resulting in insufficient flexibility and affecting the dust collection efficiency and ease of use of the floor brush. Therefore, this utility model provides a vacuum cleaner floor brush with scraper strips that adaptively adjust based on the movement direction.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a vacuum cleaner floor brush based on adaptive adjustment of the scraper blade in the direction of movement, comprising:

[0005] Ground brush body;

[0006] The front scraper bar is driven to rise and fall by a drive device and is located in the movable groove on the front side of the dust suction port at the bottom of the floor brush body;

[0007] The rear scraper includes a blocking section, a positioning section, and a deformable section disposed between the blocking section and the positioning section. The positioning section is fitted to the bottom of the floor brush body and the rear side of the suction port. The blocking section extends downward from the lower end of the deformable section, and the deformable section is a soft structure.

[0008] Several support members are positioned on the rear side of the blocking section, and their bottom and side surfaces are respectively provided with a first friction surface and a second friction surface.

[0009] As a further description of the above technical solution:

[0010] The bottom surface of the floor brush body is provided with an installation groove, and the positioning block is embedded in the installation groove. An extension block is provided on its side. The positioning section has an L-shaped structure, with the positioning strip at one end embedded in the gap between the installation groove and the extension block, and the other end fitting onto the stepped protrusion of the extension block.

[0011] As a further description of the above technical solution:

[0012] Both the positioning block and the mounting groove have assembly holes on their inner sides. Fasteners are connected to the assembly holes to install and position the positioning block and the mounting groove.

[0013] As a further description of the above technical solution:

[0014] Several insertion blocks are provided at the top of the positioning section, and the insertion blocks are inserted into the insertion holes on the extension block.

[0015] As a further description of the above technical solution:

[0017] As a further description of the above technical solution:

[0018] The bottom surface of the floor brush body has several protrusions spaced apart on both the front and rear sides of the suction port. A front air inlet is formed between adjacent protrusions on the front side, and a rear air inlet is formed between adjacent protrusions on the rear side. The horizontal cross-sections of the front and rear air inlets are trapezoidal, with their narrow sides facing the suction port.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0031] Example 1:

[0032] Please see Figure 1-5 This utility model provides a technical solution: a vacuum cleaner floor brush with adaptive adjustment of the scraper based on the direction of movement, comprising:

[0033] Floor brush body 1;

[0034] The front scraper 2, driven by a driving device, is positioned within a movable groove 4 on the front side of the dust suction port 3 at the bottom of the floor brush body 1. The driving device can be a conventional linear drive, such as an electric cylinder, which moves the front scraper 2 up and down within the movable groove 4 to switch between two usage states: retracted into the floor brush or extended beyond it and resting on the ground. Alternatively, a conventional rotary drive, such as a servo motor, can be used to swing the front scraper 2 within the movable groove 4, adjusting its lower edge to achieve the same adjustment effect. Based on these two basic driving methods, further... The design and layout of other drive mechanisms will not be elaborated on here; the drive device can be linked to the control switch on the vacuum cleaner to realize the autonomous adjustment of the position of the front scraper 2 under different movement directions and usage states, thereby improving the convenience of use. Alternatively, sensors such as cameras can be installed to identify the proximity or distance between the floor brush and surrounding objects, determine the forward or backward movement of the floor brush, and automatically control the drive device to complete the adjustment of the position of the front scraper 2. The above-mentioned user-active and vacuum cleaner automatic control methods are conventional designs in the field of vacuum cleaner control, and will not be elaborated on here.

[0035] The rear scraper 5 includes a blocking section 6, a positioning section 7, and a deformable section 8 disposed between the blocking section 6 and the positioning section 7. The positioning section 7 is fitted to the bottom of the floor brush body 1 and the rear side of the suction port 3. The blocking section 6 extends downward from the lower end of the deformable section 8, and the deformable section 8 is a soft structure.

[0036] Several support members 9 are positioned on the rear side of the blocking section 6, and their bottom and side surfaces are respectively provided with a first friction surface 10 and a second friction surface 11.

[0037] The working principle of a vacuum cleaner floor brush based on adaptive adjustment of the moving direction scraper in this embodiment includes: During use, when the floor brush moves forward, the first friction surface 10 contacts the ground, generating friction between them. This, combined with the support member 9 abutting against the bottom surface of the floor brush, causes the rear scraper 5 to be in a vertical position. The blocking section 6 abuts against the ground, sealing the air intake gap between the floor brush and the ground, and behind the floor brush suction port 3. Air enters from the front of the floor brush, and the blocking section 6 blocks dust and dirt from the ground, extending the suction time of the suction port 3. Specifically, as follows... Figure 4 As shown; when the floor brush moves backward, under the frictional force of the rear scraper 5 rubbing against the ground through the first friction surface 10, the deformable section 8 rotates and deforms forward, and the blocking section 6 flips upward to open. At this time, the second friction surface 11 rubs against the ground, and with the help of friction, the rear scraper 5 is shaped. The air intake gap at the rear of the floor brush suction port 3 opens, and air enters from the rear of the floor brush. This prevents the rear scraper 5 from blocking large particles of dust and other substances on the ground when the floor brush moves backward, thus avoiding the situation where dust cannot be sucked into the suction port 3 and affecting the floor cleaning efficiency. Specifically, as shown... Figure 5 As shown.

[0038] Example 2:

[0039] Please see Figure 2-5The figure shows a vacuum cleaner floor brush based on adaptive adjustment of the scraper strip in the direction of movement, according to Embodiment 2 of this utility model. This embodiment further improves upon the previous embodiment by making the following technical improvements: The bottom surface of the floor brush body 1 is provided with a mounting groove 12, and a positioning block 13 is embedded and positioned within the mounting groove 12. An extension block 14 is provided on its side. The positioning section 7 has an L-shaped structure, with a positioning strip 15 at one end embedded in the gap between the mounting groove 12 and the extension block 14, and its other end fitted onto the stepped protrusion 16 of the extension block 14. Assembly holes are provided on the inner sides of both the positioning block 13 and the mounting groove 12. Fasteners are connected to the assembly holes for mounting and positioning of the positioning block 13 and the mounting groove 12. Several insert blocks 17 are provided on the top of the positioning section 7, and the insert blocks 17 are inserted into the insertion holes 18 positioned on the extension block 14. This design enables the detachable connection between the mounting groove 12 and the positioning block 13, and between the positioning block 13 and the rear scraper 5. This facilitates the individual disassembly, replacement, and maintenance of the rear scraper 5, or its combination with the positioning block 13, thereby improving the stability of the dust-blocking and airflow-guiding layout of the rear scraper 5. During disassembly, the floor brush can be lifted, and the rear scraper 5 can be pulled out directly downwards for replacement and maintenance. Alternatively, fasteners (such as pins, bolts, and corresponding pin holes / screw holes) can be removed. Then, the positioning block 13 and the rear scraper 5 can be removed together for structural replacement and adjustment. During assembly, the positioning block 13 is first embedded into the mounting groove 12 and secured with fasteners. Then, the rear scraper 5 is pressed against the extension block 14, causing the positioning strip 15 to fit into the gap between the mounting groove 12 and the extension block 14. The insert block 17 is then inserted into the insertion hole 18, completing the structural installation and positioning. The rear scraper 5 is easy to assemble and disassemble, has high positioning strength, and is not prone to detachment.

[0040] Example 3:

[0041] Please see Figure 1-5 The figure shows a vacuum cleaner floor brush based on adaptive adjustment of the scraper blade in the direction of movement, according to Embodiment 3 of this utility model. This embodiment further improves upon the above embodiments by making the following technical solutions: the deformable section 8 is a soft rubber structure to improve the bending deformation capability of the rear scraper blade 5. Furthermore, the rear scraper blade 5 as a whole can be made of soft rubber material, allowing the positioning section 7 and its structure to be elastically filled and positioned on the positioning block 13 and the mounting groove 12, thereby improving assembly stability.

[0042] Example 4:

[0043] Please see Figure 1The figure shows a vacuum cleaner floor brush based on adaptive adjustment of the scraper blade in the moving direction, according to Embodiment 4 of this utility model. This embodiment further improves upon the previous embodiment by providing the following technical solution: The bottom surface of the floor brush body 1 has several protrusions 19 spaced apart on both the front and rear sides of the suction port 3. A forward air inlet 20 is formed between adjacent protrusions 19 on the front side, and a rear air inlet 21 is formed between adjacent protrusions 19 on the rear side. This results in several air inlets on both the front and rear sides of the suction port 3, allowing airflow to enter the suction port 3 from different sides, thereby increasing the suction power and airflow velocity outside the suction port 3. This makes it easier for large dust particles on the ground to be sucked up by the floor brush, thus improving suction efficiency. Specifically, the horizontal cross-section of the forward air inlet 20 and the rear air inlet 21 is trapezoidal, with its narrow side facing the suction port 3. This causes the flow area of ​​the air inlet to gradually decrease from the direction of the air inlet to the suction port 3, further increasing the wind speed. Furthermore, the mounting groove 12 and positioning block 13 in the above embodiment 2 are arranged inside the protrusion 19, which can realize structural protection and improve service life.

[0044] In summary, due to the adoption of the above technical solution, the vacuum cleaner floor brush based on adaptive adjustment of the moving direction scraper in this embodiment has the following advantages compared with the prior art:

[0045] This utility model's vacuum cleaner floor brush features a three-section structure for the rear scraper, consisting of a blocking section, a deformation section, and a positioning section. Combined with the support components and the friction surfaces on them, the scraper structure can adaptively adjust based on the direction of movement, allowing for switching between a lowered scraper when the brush moves forward and a raised scraper when it moves backward, thus improving floor cleaning and vacuuming efficiency. The bottom of the floor brush has several protrusions and air inlets on both the front and rear sides of the suction port, increasing airflow velocity and making it easier for the brush to suck up large dust and debris, further improving vacuuming efficiency. The simplified rear scraper structure reduces costs and facilitates disassembly and assembly, improving the convenience of replacement and maintenance, as well as the cleaning efficiency of the floor brush.
