Description

Technical Field

[0001] This utility model relates to the technical field of cleaning equipment, and more specifically, to a cleaning machine brush head structure and a cleaning machine. Background Technology

[0002] In the field of cleaning machines, the brush head structure, as the core component that directly acts on the surface to be cleaned, directly affects the cleaning efficiency and quality due to its water output.

[0003] In the prior art, the brush head structure of the cleaning machine usually delivers cleaning fluid or clean water through water inlet holes set on the brush seat and fluid distributor. Among them, some brush head structures adopt a solid conical design for the water inlet holes, that is, the channel of the water inlet extends in a solid conical shape, and the inner wall of the channel is a continuous conical surface.

[0004] However, the relevant technology has at least one of the following problems: the water inlet of the existing brush head structure is conically expanded, and the cleaning liquid is guided by the conical inner wall when it flows through the channel. The spray angle fluctuates with the water pressure, making it difficult to control the water outlet direction. As a result, the cleaning liquid cannot be accurately applied to the area to be cleaned, which reduces the local cleaning power and causes uneven cleaning. In addition, the water flow scattering wastes the cleaning liquid and reduces the cleaning efficiency of the cleaning machine. Utility Model Content

[0005] The technical problem solved by this utility model is that the water inlet of the existing brush head structure is conical in shape. When the cleaning liquid flows through the channel, it is guided by the conical inner wall. The spray angle fluctuates with the water pressure, making it difficult to control the water outlet direction. As a result, the cleaning liquid cannot be accurately applied to the area to be cleaned, which reduces the local cleaning power and causes uneven cleaning. In addition, the water flow scattering wastes the cleaning liquid and reduces the cleaning efficiency of the cleaning machine.

[0006] To solve the above-mentioned technical problems, on the one hand, this utility model provides a cleaning machine brush head structure, including a handle and a brush body, the brush body including: The brush holder has an installation groove and a first water inlet hole; A fluid distributor is mounted on the top of the brush holder and has a second water inlet that communicates with the first water inlet. The brush head is snapped into the mounting groove and located on the side of the brush holder away from the fluid distributor. The brush head has a water outlet hole. When the brush head is installed in the brush holder, the water outlet hole is connected to the first water delivery hole. The first and second water inlets are straight through-hole structures.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting the first and second water inlets as straight through-hole structures, this solution avoids the interference of tapered channels on the fluid's direction, ensuring a stable flow direction of the cleaning fluid as it flows through the first and second water inlets, and preventing the spray angle from being affected by water pressure fluctuations, thus accurately targeting the area to be cleaned. This not only improves local cleaning power and ensures cleaning uniformity but also reduces the waste of cleaning fluid caused by water scattering, thereby improving the cleaning efficiency of the cleaning machine.

[0008] In one embodiment of this utility model, the diameter of the first water inlet is smaller than the diameter of the second water inlet; The diameter of the outlet hole is larger than the diameter of the first water inlet hole and / or the second water inlet hole.

[0009] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting the diameter of the first water inlet to be smaller than that of the second water inlet, the fluid flows through the first and second water inlets, creating a pressurization effect and enhancing the jetting force. Furthermore, the diameter of the outlet hole is larger than that of the first and second water inlets to reduce the resistance at the fluid outlet and reduce scattering. This, combined with the linear channel, achieves directional jetting of the fluid, thereby further improving the accuracy and cleaning efficiency of the cleaning fluid impact.

[0010] In one embodiment of this utility model, the fluid dispenser and the brush holder are connected by a snap-fit ​​method; The fluid distributor is provided with a first limiting component and a second limiting component, and the brush holder is provided with a third limiting component and a fourth limiting component. When the fluid distributor is installed on the brush holder, the first limiting component cooperates with the third limiting component, and the second limiting component cooperates with the fourth limiting component.

[0011] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting the fluid distributor and brush holder to be connected by a snap-fit, and with the matching and cooperation of the first and third limiting components, as well as the second and fourth limiting components, assembly can be completed quickly, and the installation position of the fluid distributor and brush holder can be ensured to be accurate. This avoids the misalignment of the first and second water inlets due to loose connections or misaligned installation, ensuring stable fluid delivery and thus improving the stability of the cleaning machine brush head structure assembly. At the same time, it also improves the operational stability of the cleaning machine.

[0012] In one embodiment of this utility model, the fluid distributor is further provided with a limiting protrusion, and the second water delivery hole is opened through the interior of the limiting protrusion; The brush holder is provided with a limiting groove, and the first water inlet is opened in the middle area of ​​the limiting groove; When the fluid distributor is installed on the brush holder, the limiting protrusion and the limiting groove are fitted together, and a seal is also installed between their mating surfaces.

[0013] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution, through the matching and cooperation of the limiting protrusion and the limiting groove, enables the fluid distributor and the brush holder to be precisely positioned, ensuring the accurate docking of the second water inlet and the first water inlet; furthermore, a sealing element is provided between the assembly surfaces of the limiting protrusion and the limiting groove to prevent fluid leakage, and the sealing element, in conjunction with the straight through-hole structure of the first and second water inlets, further ensures the stability of the directional delivery of the cleaning fluid, thereby improving the sealing performance and water delivery efficiency of the brush head structure.

[0014] In one embodiment of this utility model, the brush head is provided with a snap-fit ​​component, and the inner side wall of the mounting groove of the brush holder is provided with a corresponding snap-fit ​​groove. When the brush head is installed in the mounting slot, the snap-fit ​​component and the slot engage in a snap-fit ​​relationship.

[0015] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution achieves quick assembly and disassembly of the brush head and brush holder by engaging the snap-fit ​​component of the brush head with the snap-fit ​​groove located on the inner side wall of the brush holder mounting groove, which facilitates the replacement and cleaning of the brush head and thus meets the requirement of brush head replacement; at the same time, the snap-fit ​​engagement ensures the connection stability between the brush head and the brush holder.

[0016] In one embodiment of this utility model, the snap-fit ​​component includes an integrally formed hand-held part and an elastic arm. The hand-held part extends outward relative to the brush head, and the elastic arm connects the brush head and the hand-held part. The elastic arm bends toward the brush head side to form a U-shaped structure with the outer side wall of the brush head. The flexible arm has an outwardly extending protrusion on the side opposite to the brush head, and the slot is a card hole that matches the protrusion. When the brush head is installed in the mounting slot, the handheld part is located outside the mounting slot. The elastic arm is squeezed by the inner wall of the mounting slot, causing elastic deformation, so that the snap-fit ​​protrusion is embedded in the slot to form a snap-fit ​​fixation.

[0017] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution sets the snap-fit ​​component as an integrally molded handheld part and elastic arm, with the elastic arm forming a U-shaped structure with the outer wall of the brush head. During installation, the elastic arm deforms under pressure, allowing the snap-fit ​​to be firmly embedded in the slot. During disassembly, pressing the handheld part drives the elastic arm to reset and disengage from the slot, improving the convenience of brush head disassembly. This solution improves the structural strength and durability of the snap-fit ​​component through the integral molding structure, ensuring stable connection between the water outlet and the first water inlet, and simplifying the brush head disassembly and assembly process, thereby enhancing the user experience.

[0018] In one embodiment of this utility model, the handle is provided with a first suction chamber, and the brush body further includes: The housing, brush holder, fluid dispenser, and brush head are installed in the housing cavity, and the housing has an opening; The cover is fitted at the opening and forms a second sludge suction chamber with the housing. The second sludge suction chamber is connected to the first sludge suction chamber.

[0019] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution forms a second sludge extraction chamber by enclosing the shell and the cover, which communicates with the first sludge extraction chamber inside the handle, thus constructing a complete sludge extraction channel. This allows for the timely extraction of wastewater and impurities from the cleaned area, preventing secondary pollution from residual wastewater and reducing ineffective waste of cleaning fluid. Furthermore, the assembly of the cover and the shell facilitates the cleaning and maintenance of the sludge extraction channel, improving the cleanliness of the comb structure in the cleaning machine.

[0020] In one embodiment of this utility model, the handle is also provided with a water delivery chamber adjacent to the first sludge suction chamber, and a water delivery pipe is installed in the water delivery chamber. The fluid distributor is provided with an inlet that is connected to the water delivery pipe.

[0021] Compared with existing technologies, the technical effects achieved by this solution are as follows: By placing the water delivery chamber and the first sludge suction chamber adjacent to each other inside the handle, this solution achieves independent separation of the water delivery and sludge suction channels, avoiding mutual interference between the cleaning fluid and the sewage; the water delivery pipe is precisely connected to the second water delivery hole through the inlet of the fluid distributor, ensuring stable delivery of the cleaning fluid. Combined with the directional effect of the linear first water delivery hole and the linear second water delivery hole, the accuracy of the cleaning fluid output position is further improved.

[0022] In one embodiment of this utility model, the cover is provided with a slot, and the cleaning machine brush head structure further includes: Wiper blade; The wiper blade is inserted into the slot and is located on the side edge of the brush head away from the brush holder, extending along the length of the brush head; The bottom of the wiper blade has an inclined wiping edge, which is inclined towards the cleaning surface of the brush head.

[0023] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution facilitates the disassembly and replacement of the squeegee by inserting it into the slot of the cover; furthermore, the inclined squeegee blade at the bottom of the squeegee faces the cleaning surface to scrape the sewage to the inner suction port, which, together with the suction channel formed by the second and first suction chambers, allows for the immediate removal of sewage, preventing sewage residue from spreading; even further, the squeegee extends along the length of the brush head, increasing the squeegee coverage area and further enhancing the cleaning efficiency of the cleaning machine.

[0024] On the other hand, this utility model also provides a cleaning machine, which includes: The main unit includes a housing assembly, a liquid supply assembly, a water supply tank, and a sludge suction assembly, which are mounted on the housing assembly.

Detailed Implementation

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 10 As shown, this utility model provides a cleaning machine brush head structure, including a handle 100 and a brush body 200. The brush body 200 includes a brush base 300, a fluid distributor 400, and a brush head 500. Specifically, the brush base 300 has an installation groove 310 and a first water inlet 320. The fluid distributor 400 is mounted on the top of the brush base 300 and has a second water inlet 410 communicating with the first water inlet 320. The brush head 500 is snapped into the installation groove 310 and located on the side of the brush base 300 away from the fluid distributor 400. The brush head 500 has a water outlet 510. When the brush head 500 is installed on the brush base 300, the water outlet 510 communicates with the first water inlet 320. The first water inlet 320 and the second water inlet 410 are straight through-hole structures.

[0031] Specifically, this solution sets the first water inlet 320 and the second water inlet 410 as a straight through-hole structure, which avoids the interference of the conical channel on the fluid guidance. This ensures that the flow direction of the cleaning fluid is stable when it flows through the first water inlet 320 and the second water inlet 410, and the spray angle is not affected by water pressure fluctuations, thus accurately acting on the area to be cleaned. This not only improves the local cleaning power and ensures the uniformity of cleaning, but also reduces the waste of cleaning fluid caused by water flow scattering, thereby improving the cleaning efficiency of the cleaning machine.

[0032] like Figures 6 to 8 As shown, in one embodiment of this utility model, the diameter of the first water inlet 320 is smaller than the diameter of the second water inlet 410; the diameter of the outlet 510 is larger than the diameter of the first water inlet 320 and / or the second water inlet 410 (as shown in the figure, the outlet 510 has a conical structure, and the conical structure is conically expanded).

[0033] Specifically, this solution sets the diameter of the first water inlet 320 to be smaller than that of the second water inlet 410, so that the fluid flowing through the first water inlet 320 and the second water inlet 410 will have a pressurization effect, thereby enhancing the spray force. Furthermore, the diameter of the outlet 510 is larger than that of the first water inlet 320 and the second water inlet 410, so as to reduce the resistance at the fluid outlet and reduce scattering. In combination with the straight channel, it achieves the effect of directional spraying of the fluid, thereby further improving the accuracy of the cleaning fluid impact and the cleaning efficiency.

[0034] In some embodiments, the water outlet 510 can also be a straight through-hole structure.

[0035] like Figures 1 to 4 As shown, in one embodiment of this utility model, the fluid distributor 400 and the brush holder 300 are connected by a snap-fit ​​method; wherein, the fluid distributor 400 is provided with a first limiting component 420 and a second limiting component 430, and the brush holder 300 is provided with a third limiting component 330 and a fourth limiting component 340. When the fluid distributor 400 is installed on the brush holder 300, the first limiting component 420 and the third limiting component 330 cooperate, and the second limiting component 430 and the fourth limiting component 340 cooperate.

[0036] Specifically, this solution connects the fluid distributor 400 and the brush holder 300 via a snap-fit ​​connection. Combined with the matching of the first and third limiting components, and the second and fourth limiting components, this allows for rapid assembly while ensuring precise installation of the fluid distributor 400 and the brush holder 300. This prevents misalignment between the first water inlet 320 and the second water inlet 410 due to loose connections or misaligned installation, ensuring stable fluid delivery and thus improving the stability of the cleaning machine's brush head assembly. This also enhances the overall operational stability of the cleaning machine.

[0037] As shown in the figure, the first and second limiting components are arc structures set at both ends of the fluid distributor 400, and the third limiting component 330 and the fourth limiting component 340 are circular cylinders set at the top of both ends of the brush holder 300. When the fluid distributor 400 is installed on the brush holder 300, the arc structure and the circular cylinder cooperate with each other to ensure that the installation position of the fluid distributor 400 and the brush holder 300 is accurately engaged.

[0038] like Figures 6 to 8 As shown, in one embodiment of this utility model, the fluid distributor 400 is further provided with a limiting protrusion 440, and a second water inlet 410 is opened through the interior of the limiting protrusion 440; the brush holder 300 is correspondingly provided with a limiting groove 350, and a first water inlet 320 is opened in the middle region of the limiting groove 350; wherein, when the fluid distributor 400 is installed on the brush holder 300, the limiting protrusion 440 and the limiting groove 350 form a matching fit, and a sealing element 600 is also installed between the two mounting surfaces.

[0039] Specifically, this solution, through the matching and cooperation of the limiting protrusion 440 and the limiting groove 350, enables the fluid distributor 400 and the brush holder 300 to be precisely positioned, ensuring the precise docking of the second water inlet 410 and the first water inlet 320. Furthermore, a sealing element 600 is provided between the assembly surfaces of the limiting protrusion 440 and the limiting groove 350 to prevent fluid leakage. The sealing element 600, in conjunction with the linear through-hole structure of the first water inlet 320 and the second water inlet 410, further ensures the stability of the directional delivery of the cleaning fluid, thereby improving the sealing performance and water delivery efficiency of the brush head 500 structure.

[0040] like Figures 1 to 5 As shown, in one embodiment of this utility model, the brush head 500 is provided with a snap-fit ​​member 520, and the inner side wall of the mounting groove 310 of the brush holder 300 is provided with a corresponding snap-fit ​​groove 360; wherein, when the brush head 500 is installed in the mounting groove 310, the snap-fit ​​member 520 and the snap-fit ​​groove 360 ​​form a snap-fit ​​engagement.

[0041] Specifically, this solution achieves quick assembly and disassembly of the brush head 500 and the brush holder 300 by engaging the snap-fit ​​component 520 of the brush head 500 with the snap-fit ​​groove 360 ​​located on the inner side wall of the mounting groove 310 of the brush holder 300. This facilitates the replacement and cleaning of the brush head 500, thus fulfilling the requirement for replaceable brush head 500. At the same time, the snap-fit ​​engagement ensures the connection stability between the brush head 500 and the brush holder 300.

[0042] like Figures 1 to 5As shown, in one embodiment of this utility model, the snap-fit ​​component 520 includes an integrally formed handheld part 521 and an elastic arm 522. The handheld part 521 extends outward relative to the brush head 500, and the elastic arm 522 connects the brush head 500 and the handheld part 521. The elastic arm 522 bends towards the side of the brush head 500 to form a U-shaped structure with the outer wall of the brush head 500. The side of the elastic arm 522 away from the brush head 500 is provided with an outwardly extending snap protrusion 523, and the snap groove 360 ​​is a snap hole 361 adapted to the snap protrusion 523. When the brush head 500 is installed in the mounting groove 310, the handheld part 521 is located outside the mounting groove 310, and the elastic arm 522 is squeezed by the inner wall of the mounting groove 310 to generate elastic deformation, so that the snap protrusion 523 is embedded in the snap groove 360 ​​to form a snap-fit ​​fixation.

[0043] Specifically, this solution sets the snap-fit ​​component 520 as an integrally molded handheld part 521 and elastic arm 522, with the elastic arm 522 forming a U-shaped structure with the outer wall of the brush head 500. During installation, the elastic arm 522 deforms under pressure, causing the snap protrusion 523 to embed into the slot 360 for secure fixation. During disassembly, pressing the handheld part 521 drives the elastic arm 522 to reset and disengage from the slot 360, improving the ease of disassembling the brush head 500. This solution enhances the structural strength and durability of the snap-fit ​​component 520 through its integrally molded structure, ensuring stable connection between the water outlet 510 and the first water inlet 320, and simplifying the disassembly and assembly process of the brush head 500, thereby improving the user experience.

[0044] like Figures 1 to 10 As shown, in one embodiment of this utility model, the handle 100 is provided with a first sludge suction chamber 110, and the brush body 200 also includes a housing 700 and a cover 800. Specifically, the brush holder 300, the fluid distributor 400, and the brush head 500 are installed in the receiving cavity of the housing 700, and the housing 700 has an opening. The cover 800 is fitted into the opening, and the cover 800 and the housing 700 enclose to form a second sludge suction chamber 900, and the second sludge suction chamber 900 is connected to the first sludge suction chamber 110.

[0045] Specifically, this solution uses the housing 700 and the cover 800 to form a second sludge extraction chamber 900, which is connected to the first sludge extraction chamber 110 inside the handle 100, thus constructing a complete sludge extraction channel. This allows for the timely extraction of wastewater and impurities from the cleaned area, preventing secondary pollution from residual wastewater and reducing ineffective waste of cleaning fluid. Furthermore, the assembly of the cover 800 and the housing 700 facilitates the cleaning and maintenance of the sludge extraction channel, improving the cleanliness of the comb structure of the cleaning machine.

[0046] like Figure 9 and Figure 10As shown, in one embodiment of the present invention, the handle 100 is further provided with a water delivery chamber 120 adjacent to the first sludge suction chamber 110. A water delivery pipe 121 is installed in the water delivery chamber 120, and an inlet 450 connected to the water delivery pipe 121 is provided on the fluid distributor 400.

[0047] Specifically, this solution achieves independent separation of the water supply and sludge suction channels by placing the water supply chamber 120 and the first sludge suction chamber 110 adjacently within the handle 100, thus avoiding mutual interference between the cleaning fluid and the sewage. The water supply pipe 121 is precisely connected to the second water supply hole 410 through the inlet 450 of the fluid distributor 400, ensuring stable delivery of the cleaning fluid. Combined with the directional effect of the linear first water supply hole 320 and the linear second water supply hole 410, the accuracy of the cleaning fluid output position is further improved.

[0048] like Figure 9 and Figure 10 As shown, in one embodiment of this utility model, the cover 800 is provided with a slot, and the cleaning machine brush head structure also includes a squeegee 810; the squeegee 810 is inserted into the slot and is located on the side edge of the brush head 500 away from the brush seat 300, extending along the length direction of the brush head 500; wherein, the bottom of the squeegee 810 forms an inclined squeegee blade, the inclined direction of the squeegee blade is towards the cleaning working surface of the brush head 500, and the cover 800 is provided with a sludge suction port 820 connected to the second sludge suction chamber 900 at the position inside the squeegee 810.

[0049] Specifically, this solution involves inserting the squeegee 810 into the slot of the cover 800 for easy disassembly and replacement. Furthermore, the squeegee blade at the bottom of the squeegee 810 faces the cleaning surface to scrape wastewater to the inner suction port 820. This, combined with the suction channel formed by the second suction chamber 900 and the first suction chamber 110, ensures timely removal of wastewater and prevents residual wastewater from spreading. Moreover, the squeegee 810 extends along the length of the brush head 500, increasing the squeegee coverage area and further enhancing the cleaning efficiency of the cleaning machine.

[0050] On the other hand, this utility model also provides a cleaning machine, which includes: The main unit includes a housing assembly, a liquid supply assembly, a water supply tank, and a sludge extraction assembly, which are mounted on the housing assembly.
