[0029] refer to Figure 1 A cleaning and disinfecting liquid 230 is used to be set in the brush head 200. The cleaning and disinfecting liquid 230 includes the following components in terms of weight percentage: 5-15% glycolic acid, 5-15% preservative, 20-35% cationic surfactant, 2-8% non-ionic surfactant, 2-15% thickener, and the rest is water.

[0030] The cationic surfactant in the cleaning and disinfecting liquid 230 plays a cleaning role, the nonionic surfactant is used to enhance the cleaning ability of the cationic surfactant, the glycolic acid plays a bleaching and certain cleaning and disinfecting role, and the preservative is used to prevent the cleaning and disinfecting liquid 230 from spoiling and deteriorating, so that the cleaning and disinfecting liquid 230 has a certain shelf life. The cleaning and disinfecting liquid 230 of the present application is directly set in the brush head 200, so when the brush head 200 with the cleaning and disinfecting liquid 230 of the present application is used for cleaning, it is not necessary to add the external cleaning and disinfecting liquid 230 to the brush head 200. The cleaning and disinfecting liquid 230 can be directly added to the brush head 200 of the cleaning brush, or the external cleaning and disinfecting liquid 230 can be directly added to the place to be cleaned, and the brush head 200 with the cleaning and disinfecting liquid 230 of the present application can be used for cleaning, so that the cleaning process is very convenient. Moreover, since the cleaning and disinfecting liquid 230 of the present application contains a thickener, the cleaning and disinfecting liquid 230 of the present application has a certain viscosity, and the fluidity of the cleaning and disinfecting liquid 230 is relatively small, so that the cleaning and disinfecting liquid 230 set in the brush head 200 of the present application will not flow out of the brush head 200 when not in use.

[0031] In the present embodiment, the weight of glycolic acid, preservatives, cationic surfactants, nonionic surfactants and thickeners accounts for a relatively high proportion of the weight of the cleaning and disinfecting liquid 230, so that the weight of the deionized water of the present application accounts for a significantly lower proportion of the weight of the cleaning and disinfecting liquid 230 than the weight of the deionized water in ordinary cleaning and disinfecting liquids, so that the fluidity of the cleaning and disinfecting liquid 230 of the present application is smaller than the fluidity of ordinary cleaning and disinfecting liquids, thereby further ensuring that the cleaning and disinfecting liquid 230 of the present application disposed in the brush head 200 will not flow out of the brush head 200 when not in use.

[0032] In this embodiment, the brush head 200 having the cleaning and disinfecting liquid 230 of the present application is used to clean household appliances. Furthermore, the household appliance can be a toilet. Furthermore, the amount of glycolic acid is controlled so that the pH value of the cleaning and disinfecting liquid 230 is 3-4. The strongly acidic cleaning and disinfecting liquid 230 can effectively remove alkaline dirt, calcium, rust, etc. in the toilet, and can play a bleaching role. Specifically, this formula uses glycolic acid of special specifications (referring to technical grade glycolic acid), and technical grade glycolic acid has a strong bactericidal effect on Escherichia coli, Staphylococcus aureus, and Candida albicans.

[0033] Furthermore, the preservative includes at least one of glutaraldehyde, triclosan and citric acid. Specifically, glutaraldehyde, triclosan and citric acid all have strong preservative functions and can well improve the shelf life of the cleaning and disinfecting solution 230.

[0034] Furthermore, the cationic surfactant includes at least one of sodium lauryl sulfate, sodium fatty alcohol polyoxyethylene ether sulfate and sodium dodecylphenyl ether disulfonate. Specifically, the cationic surfactant has a strong grease removal ability, and cooperates with glycolic acid to achieve diversified and comprehensive grease and dirt removal capabilities.

[0035] Furthermore, the nonionic surfactant includes C8-12 alkyl glycosides. Specifically, the nonionic surfactant can enhance the degreasing ability of the cationic surfactant, and the presence of the nonionic surfactant makes it easier to generate more foam when cleaning with the cleaning and disinfecting liquid, and the visual effect is better. In addition, the C8-12 alkyl glycosides are biodegradable, less polluting, and more environmentally friendly.

[0036] Furthermore, the thickener includes at least one of coconut acid and coconut acid diethanolamide. Specifically, the thickener increases the viscosity of the cleaning and disinfecting liquid 230. When producing the brush head 200 with the cleaning and disinfecting liquid 230, it is convenient to add the cleaning and disinfecting liquid 230 into the brush head 200. After the production of the brush head 200 with the cleaning and disinfecting liquid 230 is completed, the cleaning and disinfecting liquid 230 will not flow out of the brush head 200.

[0037] Furthermore, the cleaning and disinfecting solution 230 also includes 0.5-2.0% by weight of acid-resistant color powder. Specifically, the addition of the acid-resistant color powder makes the cleaning and disinfecting solution 230 have a distinct color, which is convenient for users to distinguish the cleaning and disinfecting solution 230. Moreover, the acid-resistant color powder is acid-resistant, thereby being able to avoid being decomposed by glycolic acid. Furthermore, the color of the acid-resistant color powder can be but is not limited to blue or purple.

[0038] Furthermore, the cleaning and disinfecting liquid 230 also includes 0.3-2% by weight of essence. Specifically, the addition of essence can remove odors and bad smells emitted from the places to be cleaned when the brush head 200 with the cleaning and disinfecting liquid 230 is used for cleaning, and the user can smell the fragrance during cleaning, thereby improving the user's cleaning experience. Furthermore, the essence can be but is not limited to a fresh fragrance or a lavender fragrance.

[0039] refer to Figure 1 The present application also provides a brush head 200, which includes a brush head body 240 and the above-mentioned cleaning and disinfecting liquid 230. The cleaning and disinfecting liquid 230 is arranged in the brush head body 240, and when the cleaning and disinfecting liquid 230 does not contact the external water, the cleaning and disinfecting liquid 230 can adhere to the brush head body 240 through its own viscosity. When the cleaning and disinfecting liquid 230 contacts the external water, the cleaning and disinfecting liquid 230 can be dissolved in the external water and flow out to the outside of the brush head body 240 together with the external water.

[0040] In an embodiment, when the brush head 200 is used for cleaning, the brush head 200 is first placed in water to absorb water, and the cleaning and disinfecting liquid 230 comes into contact with the external water and dissolves in the external water. When the brush head 200 comes into contact with the surface to be cleaned for cleaning, the brush head 200 is squeezed, so that the cleaning and disinfecting liquid in the brush head body 240 can flow out quickly to the outside of the brush head body 240 together with the external water under the action of squeezing, and then the brush head 200 is used to clean the surface to be cleaned.

[0041] Furthermore, if Figure 1-3 As shown, the brush head body 240 includes a fixing member 210 and a cleaning member 220, and the cleaning member 220 includes a first scouring pad 221 and a second scouring pad 222. The first scouring pad 221 is arranged on the fixing member 210, and the second scouring pad 222 is connected to an end of the first scouring pad 221 away from the fixing member 210, and a flow channel 223 connected to the outside is provided between the first scouring pad 221 and the second scouring pad 222. A cleaning and disinfecting liquid 230 is arranged in the first scouring pad 221, and when the cleaning and disinfecting liquid 230 does not contact the outside water, the cleaning and disinfecting liquid 230 can adhere to the first scouring pad 221 through its own viscosity, and when the cleaning and disinfecting liquid 230 contacts the outside water, the cleaning and disinfecting liquid 230 can dissolve in the outside water and flow out through the flow channel 223 together with the outside water. To the outside, specifically, when the brush head 200 is not in use, the cleaning and disinfecting liquid 230 is set on the first scouring pad 221. Since the cleaning and disinfecting liquid 230 of the present application contains a thickener, the cleaning and disinfecting liquid 230 of the present application has a certain viscosity, so that the cleaning and disinfecting liquid 230 on the first scouring pad 221 will not flow to the outside through the flow channel 223. When the brush head 200 is needed for cleaning, the brush head 200 is directly placed in the water, and the water will flow into the first scouring pad 221 through the flow channel 223. When the brush head 200 is used to contact the surface to be cleaned for cleaning, the cleaning and disinfecting liquid 230 in the first scouring pad 221 will quickly flow out from the first scouring pad 221 through the flow channel 223 under the action of squeezing together with the water, so that the surface to be cleaned can be reliably cleaned.

[0042] In other embodiments, the number of the second scouring pads 222 may be multiple, and the first scouring pad 221 and the multiple second scouring pads 222 are arranged in sequence. Specifically, during cleaning, the multiple second scouring pads 222 can be cleaned together, thereby improving the cleaning efficiency.

[0043] Furthermore, the cleaning member 220 is bonded to the fixing member 210. Specifically, the cleaning member 220 is bonded to the fixing member 210 by glue. In the present embodiment, the first scouring pad 221 is bonded to the fixing member 210 by glue.

[0044] Furthermore, the cleaning and disinfecting liquid 230 is arranged at a non-edge position of the first scouring pad 221. Specifically, since the cleaning and disinfecting liquid 230 is a certain distance away from the edge position of the first scouring pad 221, the cleaning and disinfecting liquid 230 needs to travel a longer distance to flow to the outside through the flow channel 223, thereby further ensuring that the cleaning and disinfecting liquid 230 will not flow to the outside through the flow channel 223 when the brush head 200 is not used for cleaning.

[0045] Furthermore, the first scouring pad 221 is made of a water-absorbent material, and the second scouring pad 222 is made of a non-water-absorbent material. Specifically, when cleaning is required, the brush head 200 is placed in water, the first scouring pad 221 will absorb water, and the cleaning and disinfecting liquid 230 in the first scouring pad 221 will dissolve in the water, so that the water dissolved with the cleaning and disinfecting liquid 230 will flow out through the first scouring pad 221 or the flow channel 223, thereby facilitating the cleaning process. In this embodiment, the weight of the water absorbed by the first scouring pad 221 is 10-20 times the weight of the brush head 200, and the cleaning and disinfecting liquid 230 will dissolve in the water to produce cleaning foam.

[0046] Furthermore, the hardness of the first scouring pad 221 is greater than that of the second scouring pad 222, that is, the hardness of the first scouring pad 221 is greater, so that when the brush head 200 is used for cleaning, the first scouring pad 221 bonded to the fixing part 210 is not easily torn by external force, making the bonding between the first scouring pad 221 and the fixing part 210 more reliable. In addition, the hardness of the second scouring pad 222 is smaller and the flexibility is better, so that when the brush head 200 is used for cleaning, the shape of the second scouring pad 222 can be adaptively changed according to the shape of the place to be cleaned, so that cleaning of each corner can be achieved.

[0047] Furthermore, the first scouring pad 221 and the second scouring pad 222 are welded by point-to-point ultrasonic welding. Specifically, the first scouring pad 221 and the second scouring pad 222 are connected at the ultrasonic welding point. In the area outside the ultrasonic welding point, the first scouring pad 221 and the second scouring pad 222 are in a separated state. The area outside the ultrasonic welding point of the first scouring pad 221 and the second scouring pad 222 is the flow channel 223. In the present embodiment, the cleaning and disinfecting liquid 230 is not provided at the ultrasonic welding point of the first scouring pad 221 and the second scouring pad 222.

[0048] In this embodiment, reference Figure 1 and Figure 3, starting from the end of the second scouring pad 222 away from the first scouring pad 221, point-to-point ultrasonic welding is performed between the first scouring pad 221 and the second scouring pad 222, so that the end of the second scouring pad 222 away from the first scouring pad 221 generates a depression 2211 toward the first scouring pad 221 at the ultrasonic welding point, so that the end of the second scouring pad 222 away from the first scouring pad 221 forms a concave-convex three-dimensional surface layer, which has a good friction effect, and then the concave-convex three-dimensional surface layer of the first scouring pad 221 can reliably clean the place to be cleaned, and the depression 2211 of the first scouring pad 221 can accommodate a certain amount of dirt, thereby facilitating the disposal of the dirt.

[0049] Furthermore, if Figure 1 As shown, the second scouring pad 222 has a first side 2221 and a second side 2222 that are relatively arranged. The second side 2222 is the side of the second scouring pad 222 facing the first scouring pad 221. Starting from the first side 2221 of the second scouring pad 222 and passing through the second side 2222 to the first scouring pad 221, point-to-point ultrasonic welding is performed between the first scouring pad 221 and the second scouring pad 222.

[0050] Furthermore, the components of the first scouring pad 221 and the second scouring pad 222 contain the same raw materials, so that the first scouring pad 221 and the second scouring pad 222 have certain identities, which makes the ultrasonic welding between the first scouring pad 221 and the second scouring pad 222 more firm and reliable. In addition, since the first scouring pad 221 and the second scouring pad 222 of the present application are welded by point-to-point ultrasonic welding, there is no need to bond them with glue, etc., thereby saving costs.

[0051] Furthermore, the diameter of the ultrasonic welding point of the first scouring pad 221 and the second scouring pad 222 is 0.1 mm-5 mm.

[0052] Furthermore, if Figure 3 As shown, there are multiple ultrasonic welding points between the first scouring pad 221 and the second scouring pad 222. Specifically, the connection between the first scouring pad 221 and the second scouring pad 222 is more reliable through the multiple ultrasonic welding points.

[0053] Furthermore, if Figure 3As shown, a cutout 2212 is provided at one end of the cleaning member 220 away from the fixing member 210. Specifically, when storing or transporting the brush head 200, the fixing member 210 of one brush head 200 can be inserted into the cutout 2212 of the cleaning member 220 of another brush head 200, thereby saving the space occupied by the brush head 200. In the present embodiment, the cutout 2212 is located at one end of the first scouring pad 221 away from the second scouring pad 222, and the cleaning and disinfecting liquid 230 is not provided at the cutout 2212 of the first scouring pad 221 to prevent the cleaning and disinfecting liquid 230 from flowing out to the outside through the cutout 2212.

[0054] Furthermore, if Figure 3 As shown, the cutout 2212 is located at the center of the cleaning member 220. On the one hand, it looks more beautiful. On the other hand, when the fixing member 210 of one brush head 200 is inserted into the cutout 2212 of the cleaning member 220 of another brush head 200, the two brush heads 200 can be aligned, thereby further saving the space occupied by the brush heads 200. Furthermore, the cutout 2212 is a cross cutout with a larger opening, thereby facilitating the insertion of the fixing member 210 into the cross cutout.

[0055] Furthermore, the cleaning member 220 is cylindrical, polyhedral or irregular. Specifically, the shape of the cleaning member 220 can be arbitrarily selected according to actual needs, as long as the cleaning work can be achieved by the cleaning member 220. In the present embodiment, the first scouring pad 221 is cylindrical, polyhedral or irregular, and the shape of the second scouring pad 222 is the same as the shape of the first scouring pad 221.

[0056] The present application also provides a cleaning brush, such as Figure 4 As shown, the cleaning brush includes a handle 100 and the brush head 200. The brush head 200 is arranged on the handle 100. Specifically, when cleaning is needed, the user holds the handle 100 to perform the cleaning operation. The user does not need to touch the brush head 200 and the area to be cleaned, making the cleaning process safer and more convenient.

[0057] Furthermore, the brush head 200 is detachably disposed on the handle 100. Specifically, the brush head 200 can be directly removed from the handle 100 and discarded after use, and a new brush head 200 can be replaced at any time according to demand.

[0058] Furthermore, if Figure 1 and Figure 5 As shown, a clamping end 211 is provided at one end of the fixing member 210 away from the cleaning member 220, and the handle 100 can clamp the clamping end 211 to achieve a detachable connection of the brush head 200 relative to the handle 100. Specifically, the setting of the clamping end 211 facilitates the clamping of the fixing member 210 by the handle 100.

[0059] Furthermore, if Figure 1 and Figure 5 As shown, an annular groove 2111 is provided on the clamping end 211, and the handle 100 can be supported on opposite sides of the annular groove 2111 so that the handle 100 can clamp the fixing member 210. Specifically, the setting of the annular groove 2111 makes the handle 100 clamp the fixing member 210 more stably and reliably.

[0060] In this embodiment, the cleaning brush is a toilet brush, and the cleaning effect of the cleaning and disinfecting liquid 230 contained in the six brush heads 200 of the present application is equivalent to the cleaning effect of a 500ML bottle of conventional toilet cleaner on the market.

[0061] Since the cleaning and disinfecting liquid 230 of the present application is arranged in the cleaning part 220, and since the cleaning and disinfecting liquid 230 contains a thickener, the cleaning and disinfecting liquid 230 of the present application has a certain viscosity, and the cleaning and disinfecting liquid 230 can be stored in the cleaning part 220. Therefore, when the consumer unpacks the brush head 200, assembles the brush head 200 to the handle 100 or cleans the cleaning brush, the user does not need to directly contact the cleaning and disinfecting liquid 230 with his hands, thereby avoiding the user's hands from being damaged by the cleaning and disinfecting liquid 230.

[0062] Since the second cleaning pad 222 of the present application is softer than the first cleaning pad 221, when the cleaning brush is used to clean the toilet, the second cleaning pad 222 can adaptively change its shape according to the irregular areas on the inner surface of the toilet, so as to always fit the inner surface of the toilet, achieve full coverage of cleaning, and remove dirt without dead corners.

[0063] When the toilet needs to be cleaned with a cleaning brush, the brush head 200 is placed in water, the first scouring pad 221 absorbs water, the cleaning and disinfecting liquid 230 is dissolved in the water, the handle 100 is held and pressed downward, pressure is generated between the first scouring pad 221 and the second scouring pad, and the cleaning and disinfecting liquid 230 dissolved in the water quickly generates foam and quickly seeps out through the first scouring pad 221 or the flow channel 223. After the brush head 200 comes out of water, it wipes the inner surface of the toilet water surface, which can kill 99.9% of Escherichia coli, Staphylococcus aureus, and Candida albicans within 10 minutes.

[0064] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent device transformations made using the contents of the present invention's specification and drawings, or direct / indirect applications in other related technical fields, under the inventive concept of the present invention are included in the patent protection scope of the present invention.
