Detailed implementation manners

[0029] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific implementation manners.

[0030] The present invention provides a foam cleaning brush head, which is applied to a fabric cleaning machine. As Figures 1 to 5As shown in the figure, the foam cleaning brush head includes a body 1, a foam generating assembly 2, and a nozzle assembly 3. The body 1 has a cleaning surface, on which a foam outlet 111 and a suction inlet 112 are arranged close to each other. The suction inlet 112 is communicated with the suction channel 9 of the fabric cleaning machine. The foam generating assembly 2 is arranged inside the body 1. The foam generating assembly 2 includes a cleaning liquid tank 21 and a pump body 22. The pump inlet of the pump body 22 is communicated with the cleaning liquid tank 21. The nozzle assembly 3 is arranged inside the body 1. The nozzle assembly 3 includes a filter element 31. The pump outlet of the pump body 22 is communicated with the foam outlet 111 on the body 1 through the nozzle assembly 3. The filter element 31 acts on the foam body discharged by the pump body 22, so that the foam body after the action of the filter element 31 is discharged through the foam outlet 111.

[0031] The above-mentioned cleaning surface can be parallel to the horizontal plane or form a certain angle with the horizontal plane. When using the foam cleaning brush head, the cleaning surface can be attached to the surface to be cleaned to ensure the cleaning effect.

[0032] The above-mentioned pump body 22 can extract the cleaning liquid in the cleaning liquid tank 21, and compress and stir the cleaning liquid to form a foam body.

[0033] The shape of the above-mentioned filter element 31 can be net-shaped. The net-shaped filter element 31 can divide the foam body flowing through the filter element 31, so that the foam body discharged from the foam outlet 111 is denser, thereby improving the cleaning effect of the foam cleaning brush head.

[0034] The above-mentioned foam outlet 111 and suction inlet 112 are arranged close to each other. After the foam body discharged from the foam outlet 111 finishes cleaning, the used dirty foam body can be quickly sucked into the fabric cleaning machine by the suction inlet 112, avoiding the dirty foam staying on the surface to be cleaned for a long time.

[0035] The above-mentioned body 1 can be made of at least partially transparent material. In this way, users can observe the operation of each component inside the body 1, and can also observe the color change of the foam body to help users evaluate the cleaning effect of the foam cleaning brush head.

[0036] The above-mentioned nozzle assembly 3 can also include components such as a nozzle cover 32 and a nozzle inner bracket 33. Through the above components, the nozzle assembly 3 can be firmly fixed inside the body 1.

[0037] The above-mentioned foam generating assembly 2 further includes a connecting hose 23 and a gravity body. One end of the connecting hose 23 is connected to the pump body 22, and the other end is connected to the gravity body. The gravity body is located at the bottom of the cleaning liquid tank 21, so that the pump body 22 is communicated with the cleaning liquid tank 21 via the connecting hose 23 and the gravity body. Through the gravity body and the connecting hose 23, the cleaning liquid at the bottom of the cleaning liquid tank 21 can be pumped into the pump body 22, avoiding the situation that the pump body 22 cannot pump the cleaning liquid when the liquid level in the cleaning liquid tank 21 is relatively low, effectively ensuring the working efficiency of the foam generating assembly 2 and further improving the practicability of the foam cleaning brush head.

[0038] The above-mentioned gravity body can be located at the bottom of the cleaning liquid tank 21 under the action of its own gravity to ensure that the pump body 22 can suck the cleaning liquid at the bottom of the cleaning liquid tank 21.

[0039] When the pump body 22 receives an open control instruction, the pump body 22 works to form a negative pressure in the connecting hose 23. Under the action of the negative pressure, the cleaning liquid in the cleaning liquid tank 21 can flow into the pump body 22 via the gravity body and the connecting hose 23, and then be converted into a foam body by the pump body 22 and discharged from the foam outlet 111.

[0040] In the present utility model, the pump body 22 can convert the liquid in the cleaning liquid tank 21 into a foam body and discharge it from the foam outlet 111, and the foam body can be made denser through the filter element 31, thereby increasing the contact area between the foam body and the dirt and improving the cleaning effect. When the cleaning is completed, the dirty foam can be sucked into the fabric cleaning machine through the suction inlet 112 and the suction channel 9 in sequence. In this way, the cleaning effect of the foam cleaning brush head can be effectively improved, and the foam is not easily soaked into the surface to be cleaned, avoiding the situation that the surface to be cleaned is wet after the cleaning is completed, effectively protecting the item to be cleaned and improving the user experience.

[0041] In some embodiments, as Figures 2 to 5 shown, a cleaning brush 12 is further provided on the cleaning surface of the fuselage 1, and the cleaning brush 12 is arranged close to the foam outlet 111.

[0042] In the above embodiment, when encountering stubborn dirt during the cleaning process, the cleaning brush 12 can be used to repeatedly brush the surface to be cleaned to remove the stubborn dirt, further improving the cleaning effect of the foam cleaning brush head.

[0043] In some embodiments, the cleaning brush 12 and the suction inlet 112 are respectively located on opposite sides of the foam outlet 111, and the suction inlet 112 is relatively closer to the front side of the fuselage 1 than the cleaning brush 12.

[0044] In some embodiments, the pump body 22 includes a foam pump 24. The pump inlet of the foam pump 24 communicates with the cleaning liquid tank 21, and the foam discharged via the foam pump 24 is directed towards the filter element 31. Alternatively, the pump body 22 includes a water pump 25 and a filter screen 26 provided at the pump outlet of the water pump 25. The pump inlet of the water pump 25 communicates with the cleaning liquid tank 21, and the cleaning liquid discharged via the water pump 25 forms a foam directed towards the filter element 31 under the action of the filter screen 26. Among them, Figure 2 and Figure 4 the pump body 22 shown in Figure 6 includes a foam pump 24,

[0045] and the pump body 22 shown in

[0046] includes a water pump 25 and a filter screen 26. Figures 1 to 5 In this way, the foam can be directly prepared by the foam pump 24, or the foam can be prepared by the cooperation of the water pump 25 and the filter screen 26 provided at the pump outlet of the water pump 25, achieving the purpose of improving the cleaning effect.

[0047] In some embodiments, as shown in

[0048] the foam cleaning brush head further includes a switch assembly 4 electrically connected to the pump body 22. The switch assembly 4 is used to control the opening and closing of the pump body 22, and the switch assembly 4 includes at least one of the following: a micro switch assembly, a touch sensing switch assembly, and a toggle switch assembly. Among them, the micro switch assembly includes a first trigger portion 41 and a micro switch 42. The first trigger portion 41 is movably provided on the body 1, and the first trigger portion 41 is used to act on the micro switch 42 after being triggered by force, so that the micro switch 42 is switched from the closed state to the open state. The touch sensing switch assembly includes a touch sensing switch and a touch sensing control board. The touch sensing switch and the touch sensing control board are electrically connected, and the touch sensing control board is used to control the touch sensing switch to be opened or closed. The toggle switch assembly includes a second trigger portion and a toggle switch. The second trigger portion is movably provided on the body 1, and the second trigger portion is used to act on the toggle switch after being triggered by force, so that the toggle switch is switched from the closed state to the open state.

[0049] In this way, the opening and closing of the pump body 22 can be accurately controlled through the switch assembly 4, and the above structure facilitates the user's operation and flexible control of the pump body 22.

[0050] The above-mentioned microswitch assembly may further include an elastic member 43. Two ends of the elastic member 43 may respectively abut against the first trigger portion 41 and the outer sidewall of the fuselage 1. When the first trigger portion 41 is stressed, the microswitch 42 is in an open state. At this time, the elastic member 43 is compressed and deformed; when the first trigger portion 41 is released, the microswitch 42 can be maintained in a closed state under the action of the restoring force of the elastic member 43.

[0051] The above-mentioned elastic member 43 may be a spring or an elastic rubber, etc. Any component that can undergo elastic deformation when stressed is within the scope of this application, and this application does not make specific limitations thereto. The above-mentioned elastic member 43 may preferably be a spring.

[0052] In some embodiments, the filter member 31 includes a plurality of filter holes arranged in an array, and the mesh number range of the filter holes is from 80 meshes to 200 meshes. Among them, the mesh number can be understood as the number of holes on the sieve per inch. The larger the mesh number, the denser the filter holes; the smaller the mesh number, the sparser the filter holes.

[0053] The filter holes within the above-mentioned mesh number range have the best foam cleaning ability and can effectively cut the foam into finer foam.

[0054] In some embodiments, the distance range between the lower end surface and the lower surface of the cleaning brush 12 provided on the fuselage 1 is from 2 millimeters to 6 millimeters. In this way, the cleaning brush 12 can have better cleaning performance.

[0055] In some embodiments, the foam cleaning brush head further includes a first control board 5 and a battery assembly electrically connected to the first control board 5. The battery assembly is a fixed battery assembly 6 or a detachable battery assembly 11; among them, as Figure 2 and Figure 7 shown, the fixed battery assembly 6 is fixedly installed in the fuselage 1, and the first control board 5 is used to supply power to the fixed battery assembly 6 through a power cord; as Figure 8 shown, the detachable battery assembly 11 is detachably provided on the fuselage 1, and the detachable battery assembly 11 is used to supply power to the first control board 5.

[0056] In the above-mentioned embodiments, the first control board 5 can supply power to the fixed battery assembly 6 through a power cord, and the fixed battery assembly 6 can provide the electrical energy required for cleaning to the foam cleaning brush head. In this way, it is convenient for the use and carrying of the foam cleaning brush head, enabling the foam cleaning brush head to meet different usage scenarios and usage conditions, and further improving the practicality of the foam cleaning brush head.

[0057] When the power of the fixed battery assembly 6 is insufficient, the above-mentioned first control board 5 can send a control instruction to the fixed battery assembly 6 and supply power to the fixed battery assembly 6 through a power cord.

[0058] The above-mentioned fixed battery assembly 6 can supply electrical energy to the pump body 22. When the first control board 5 receives the trigger information that the micro switch 42 is in the open state, it can control the fixed battery assembly 6 to supply electrical energy to the pump body 22 to operate the pump body 22.

[0059] In the above embodiment, the foam cleaning brush head can realize the quick replacement of the detachable battery assembly 11 through the detachable battery assembly 11. That is, in the case of insufficient battery power, the detachable battery assembly 11 can be taken out and charged externally, and then reinstalled into the fuselage 1 after charging is completed. In addition, a spare detachable battery assembly 11 can also be equipped. When the used detachable battery assembly 11 has insufficient power and is taken out for charging, the spare detachable battery assembly 11 can be put in and the foam cleaning brush head can be used normally.

[0060] The above-mentioned first control board 5 can be implemented by a processor chip such as a single-chip microcomputer, a microprocessor, a programmable logic controller (PLC), a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic array (PLA), an application specific integrated circuit (ASIC) and its peripheral circuits. The present application does not make specific limitations on this.

[0061] In some embodiments, a charging interface for powering the fixed battery assembly 6 is provided on the first control board 5, and the charging interface includes at least one of the following: a TYPE-C interface, a USB interface, and a DC-JACK interface.

[0062] In some embodiments, as Figure 2 shown, the foam cleaning brush head further includes a second control board 7 and a power display component. The second control board 7 is electrically connected to the battery assembly and the power display component respectively. The second control board 7 is used to receive the power information of the battery assembly and send a control instruction to the power display component to make it display the power information.

[0063] In the above embodiment, after receiving the power information of the battery assembly, the second control board 7 can send a control instruction to the power display component to display the power information on the power display component. The user can directly understand the remaining power of the battery assembly by observing the power display component, thereby effectively improving the reliability and practicality of the foam cleaning brush head.

[0064] The above-mentioned second control board 7 can be implemented by a processor chip such as a single-chip microcomputer, a microprocessor, a programmable logic controller (PLC), a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic array (PLA), an application specific integrated circuit (ASIC) and its peripheral circuits. The present application does not make specific limitations on this.

[0069] For the fabric cleaning machine adopting the above-mentioned foam cleaning brush head, the liquid in the cleaning liquid tank 21 can be converted into a foam body by a pump body 22 and discharged from a foam outlet 111, and the foam body can be made denser through a filter element 31, thereby increasing the contact area between the foam body and the dirt. When the cleaning is completed, the dirty foam can be sucked into the fabric cleaning machine through the suction inlet 112 and the suction channel 9 in sequence. In this way, the cleaning effect of the foam cleaning brush head can be effectively improved, and the foam is not easily soaked into the surface to be cleaned, avoiding the situation that the surface to be cleaned is wet after the cleaning is completed, effectively protecting the item to be cleaned, and improving the user experience.

[0070] In the above embodiment, the fabric cleaning machine can timely extract the dirt and excess foam generated after the foam cleaning brush head cleans to the sewage tank through the suction pump, effectively ensuring the cleaning effect and use experience of the fabric cleaning machine.

[0071] The above-mentioned fabric cleaning machine may further include a hose handle 10. When the user needs to use the fabric cleaning machine for cleaning, the foam cleaning brush head can be connected to the suction pump through the hose handle 10. After pouring the cleaning liquid into the cleaning liquid tank 21, the switch assembly 4 is pressed to start the pump body 22, and the foam body is sprayed on the surface to be cleaned under the action of the pump body 22. When the cleaning is completed, the suction pump can be started to pump the dirt and excess foam body into the sewage tank, thereby completing the foam cleaning of the fabric cleaning machine.

[0072] When the suction pump is in operation, a negative pressure can be formed in the suction channel 9, and dirt and excess foam can be drawn into the sewage tank through the suction inlet 112 and the suction channel 9 in sequence under the action of the negative pressure.
