TECHNICAL FIELD

[0001] The present application relates to the technical field of utensil cleaning, in particular to a utensil cleaning tool and a manufacturing method thereof. BACKGROUND

[0002] Utensil refers to a container used to hold, store, stir or cook food, such as a seasoning jar, a pot, a bowl, a plate or a tray, etc. When cleaning utensils with water, a utensil cleaning tool is often used to make residues and oil stains separate from the utensils more quickly.

[0003] The existing utensil cleaning tools are divided into two types. The first type has a handle and is suitable for brushing ordinary utensils with general depth. The second type does not have a handle and is suitable for brushing utensils with large depth or special shape.

[0004] The existing technical solutions in the above have the following defects: the existing utensil cleaning tools cannot be suitable for both ordinary utensils with general depth and utensils with large depth or special shape, and have poor versatility. SUMMARY

[0005] In order to improve the versatility of the existing utensil cleaning tools, the present application provides a utensil cleaning tool and a manufacturing method thereof.

[0006] The first object of the present application is to provide a utensil cleaning tool, which adopts the following technical solution: A utensil cleaning tool, comprising: a handle, one end of which is formed with an adapter ring; a grippable support member, which is detachably connected with the adapter ring; a friction member, which is detachably connected with the grippable support member.

[0007] By adopting the above technical solution, when the adapter ring is connected with the grippable support member, the handle is used for the human hand to grip, and the cleaning tool is suitable for brushing ordinary utensils with general depth. When the adapter ring is disconnected from the grippable support member, the grippable support member is used for the human hand to grip, which reduces the space occupied by the utensil cleaning tool, improves the flexibility of its operation in a limited space, and is suitable for brushing utensils with large depth or special shape, and has good cleaning effect on utensils with large depth or special shape. In this way, the versatility of the utensil cleaning tool is greatly improved. When the friction member is used for a period of time or a certain number of times, the friction member can be separated from the grippable support member, so as to replace the friction member.

[0008] The present application is further provided that the grippable support member comprises: a fixed seat, the outer wall of which is connected with the inner wall of the adapter ring, one end surface of which is detachably connected with the friction member, and a liquid flow channel for liquid flow is formed on the fixed seat; The storage bin is formed on the other end surface of the fixed base and is in communication with the liquid flow channel inside; The first bellows is internally stored with the cleaning agent and is arranged in the storage bin, and a release hole is formed on the top end of the first bellows; when the first bellows is subjected to extrusion, the cleaning agent is released through the release hole, and the released cleaning agent flows through the liquid flow channel and is adsorbed on the friction member; The first reset spring is installed in the first bellows.

[0009] By adopting the above technical scheme, when the first bellows is subjected to extrusion, the volume of the first bellows gradually decreases, and the first reset spring is gradually compressed, thereby reducing the deformation degree of the first bellows and further reducing the outflow amount of the cleaning agent. The cleaning agent flows out of the release hole and flows through the liquid flow channel and is adsorbed on the friction member. When the first bellows is no longer subjected to extrusion, the first bellows spontaneously restores the deformation, and at the same time, the force of the first reset spring restoring the deformation promotes the first bellows to restore the deformation more quickly. The cleaning agent and water jointly act on the surface of the utensil, thereby improving the cleaning efficiency and improving the cleaning effect. At the same time, the water and the cleaning agent can be used to clean the stains on the friction member.

[0010] The application is further provided as follows: The second bellows is internally stored with the cleaning agent and is arranged in the handle, and the top end of the second bellows is in communication with the liquid flow channel through the flow guide pipe; when the second bellows is subjected to extrusion, the released cleaning agent flows through the flow guide pipe and the liquid flow channel and is adsorbed on the friction member; The second reset spring is installed in the second bellows; The first extrusion mechanism is installed on the storage bin and can apply extrusion force to the first bellows; The second extrusion mechanism is installed on the handle and can apply extrusion force to the second bellows.

[0011] By adopting the above technical scheme, when the inside of an ordinary utensil with a general brushing depth is brushed, the human hand applies extrusion force to the first bellows through the first extrusion mechanism to make the first bellows release the cleaning agent. When the inside of a utensil with a large brushing depth or an irregular shape is brushed, the human hand applies extrusion force to the second bellows through the second extrusion mechanism to make the second bellows release the cleaning agent, and at this time, the first extrusion mechanism and the first bellows do not participate in the work.

[0012] The application is further provided as follows: the handle comprises the following raw materials in percentage by mass: polylactic acid 60%-80%, polybutylene succinate 20%-40%, mineral filler 15%-20%, and plasticizer 5%-8%.

[0013] By adopting the above technical solution, polylactic acid (PLA), derived from corn starch, exhibits clear degradability and high hardness, thus enhancing the grip's rigidity. Polybutylene succinate (PBS) is used to improve the grip's flexibility and water resistance, compensating for PLA's tendency to become brittle when exposed to water. Mineral fillers improve the grip's rigidity and heat resistance, preventing deformation and increasing reusability. Plasticizers improve the processing flowability of the PLA and PBS blend, preventing cracking during injection molding.

[0014] This application further specifies that the grippable support comprises the following raw materials by weight percentage: 60%-80% polylactic acid, 20%-40% polybutylene succinate, 15%-20% mineral filler, and 5%-8% plasticizer.

[0015] By adopting the above technical solution, polylactic acid (PLA), derived from corn starch, exhibits clear degradability and high hardness, thus enhancing the grip's rigidity. Polybutylene succinate (PBS) is used to improve the grip's flexibility and water resistance, compensating for PLA's tendency to become brittle when exposed to water. Mineral fillers improve the grip's rigidity and heat resistance, preventing deformation and increasing reusability. Plasticizers improve the processing flowability of the PLA and PBS blend, preventing cracking during injection molding.

[0016] This application further specifies that: the handle also includes the following material by weight percentage: 0.1%-0.3% anti-hydrolysis agent; the grip support also includes the following material by weight percentage: 0.1%-0.3% anti-hydrolysis agent.

[0017] By adopting the above technical solution, the anti-hydrolysis agent is beneficial to the underwater lifespan of the handle and grip support.

[0018] This application further specifies that the friction component comprises the following raw materials by mass percentage: 60%-70% polypropylene fiber, 30%-40% bamboo fiber, 1%-3% coupling agent, and 0.5%-1% antibacterial additive.

[0019] By employing the above-mentioned technical solutions, when used in combination, polypropylene fibers provide structural support and frictional cleaning force, while bamboo fibers enhance adsorption capacity and buffer friction, forming a synergistic effect of rigid cleaning and flexible adsorption. This helps reduce the number of scrubbing cycles and improves cleaning effectiveness. Compared to traditional nylon / steel wire materials, it is less likely to generate microplastic / micrometal pollution, reducing damage to the surface of utensils. Bamboo fiber is also biodegradable, reducing environmental pollution. Compared to using only bamboo fiber or bio-based materials such as corn starch, this method gives the friction components a certain degree of hardness, making the structure less prone to deformation, ensuring cleaning power, and extending service life. It simultaneously achieves a balance between antibacterial properties, environmental friendliness, cleaning effectiveness, and durability.

[0020] The second objective of this application is to provide a method for manufacturing a utensil cleaning tool, which adopts the following technical solution: A method for manufacturing a utensil cleaning tool, comprising: S1. Pre-treat bamboo fiber; S2. According to the formula, polypropylene fiber, coupling agent, antibacterial agent and pretreated bamboo fiber are blended by melt spinning process and then extruded to form friction parts; S3. According to the formula, polylactic acid, polybutylene succinate, mineral filler and plasticizer are blended and injection molded to prepare a handle / gripable support.

[0021] This application is further configured such that, in step S3, during injection molding, 0.1%-0.3% of an anti-hydrolysis agent is added.

[0022] By adopting the above technical solutions, the lifespan of the handle and grip support components underwater is improved.

[0023] This application further includes: S4. Treat the surfaces of the handle and grippable support.

[0024] By adopting the above technical solution, a hydrophobic layer is applied to the surface of the handle and grippable support. This hydrophobic coating can block moisture penetration and prevent swelling of the handle and grippable support during long-term use. The hydrophobic coating can be made of food-grade silicone, which is highly safe and has excellent water-blocking properties.

[0025] In summary, the beneficial technical effects of this application are as follows: 1. When the adapter ring is connected to the grippable support, the handle is for hand gripping, and the cleaning tool is suitable for scrubbing ordinary utensils with moderate depth. When the adapter ring is disconnected from the grippable support, the grippable support is used for hand gripping, reducing the space occupied by the cleaning tool and improving its flexibility in confined spaces. This makes it suitable for scrubbing deeper or irregularly shaped utensils, providing better cleaning results. This greatly improves the versatility of the cleaning tool. When the friction element has been used for a period of time or too many times, it can be detached from the grippable support for easy replacement.

[0026] 2. When the first bellows is compressed, its internal volume gradually decreases, and the first return spring is gradually compressed, reducing the degree of deformation and thus reducing the outflow of detergent. The detergent flows out from the release hole and adheres to the friction components through the liquid flow channel. When the first bellows is no longer compressed, it spontaneously recovers its deformation. Simultaneously, the force of the first return spring helps the bellows recover its deformation more quickly. The detergent and water work together on the surface of the vessel, improving cleaning efficiency and effectiveness. Simultaneously, water and detergent can be used to remove stains from the friction components.

[0027] 3. When cleaning the interior of ordinary utensils of moderate depth, the human hand applies pressure to the first corrugated pipe through the first squeezing mechanism, causing the first corrugated pipe to release the detergent. When cleaning the interior of utensils of greater depth or irregular shape, the human hand applies pressure to the second corrugated pipe through the second squeezing mechanism, causing the second corrugated pipe to release the detergent. In this case, the first squeezing mechanism and the first corrugated pipe are not involved in the operation.

[0028] 4. Polylactic acid (PLA), derived from corn starch, exhibits clear degradability and high hardness, enhancing the rigidity of the grip / holding support. Polybutylene succinate (PBS) is used to improve the flexibility and water resistance of the grip / holding support, compensating for the brittleness of PLA when exposed to water. Mineral fillers improve the rigidity and heat resistance of the grip / holding support, preventing deformation and increasing reusability. Plasticizers improve the processing flowability of PLA and PBS blends, preventing cracking during injection molding.

[0029] 5. When polypropylene fiber and bamboo fiber are used in combination, the polypropylene fiber provides structural support and frictional cleaning force, while the bamboo fiber enhances adsorption capacity and buffers friction, creating a synergistic effect of rigid cleaning and flexible adsorption. This helps reduce the number of scrubbing cycles and improves cleaning effectiveness. Compared to traditional nylon / steel wire materials, it is less likely to generate microplastic / micrometal pollution, reducing damage to the surface of utensils. Bamboo fiber is also biodegradable, reducing environmental pollution. Compared to using only bamboo fiber or bio-based materials such as corn starch, this combination gives the friction components a certain degree of hardness, making the structure less prone to deformation, ensuring cleaning power, and extending service life. It simultaneously achieves antibacterial properties, environmental friendliness, cleaning effectiveness, and durability. Attached Figure Description

[0032] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0033] Reference Figure 1 This application discloses a utensil cleaning tool, including a handle 110, a grippable support 120, and a friction member 130. An adapter ring 111 is formed at one end of the handle 110. The grippable support 120 is detachably connected to the adapter ring 111. The friction member 130 is detachably connected to the grippable support 120. The friction member 130 can contact the inner / outer surface of the utensil to scrub the inner / outer surface of the utensil with water. When the adapter ring 111 is connected to the grippable support 120, the handle 110 is used for hand gripping, and the cleaning tool is suitable for scrubbing ordinary utensils of moderate depth. When the adapter ring 111 is disconnected from the grippable support 120, the grippable support 120 is used for hand gripping, reducing the space occupied by the utensil cleaning tool and improving its flexibility in confined spaces. It is suitable for scrubbing deep or irregularly shaped utensils, and provides good cleaning results for such utensils. This greatly improves the versatility of the utensil cleaning tool. When the friction element 130 has been used for a period of time or too many times, it can be detached from the grippable support 120 for easy replacement.

[0034] It should be noted that the grippable support 120 can also be detachably connected to the handle 110, reducing the use of adapters and lowering manufacturing costs. For example, a threaded blind hole / clamping blind hole can be formed on the grippable support 120. Correspondingly, a threaded rod / clamping post adapted to the threaded blind hole is provided at one end of the handle 110. The handle 110 and the grippable support 120 are connected through the threaded rod / clamping blind hole and the threaded blind hole / clamping post. Of course, the handle 110 and the grippable support 120 can also be directly connected using screws or other detachable methods.

[0035] In other embodiments, such as Figure 2 As shown, the handle 110 is an elastic metal sheet capable of elastic bending, allowing the other end of the handle 110 to connect to the grippable support 120. For example, the other end of the handle 110 is connected to the grippable support 120 via a screw. When both ends of the handle 110 are connected to the grippable support 120, a ring-shaped grip ring 140 is formed. For ordinary utensils with moderate brushing depth, only one end of the handle 110 is connected to the grippable support 120, while the other end is disconnected. When brushing deeper or irregularly shaped utensils, both ends of the handle 110 are connected to the grippable support 120, reducing the overall space occupied and improving flexibility in confined spaces.

[0036] In some embodiments, the friction element 130 is hemispherical in shape and has a certain degree of flexibility. When in use, it has a large contact area with the vessel and can make full contact with the corners of the vessel, effectively improving the cleaning effect.

[0037] Reference Figure 3 , Figure 4 and Figure 5The gripping support 120 includes a fixed base 121, a storage chamber 122, a first bellows 123, and a first return spring 124. An internal thread is formed on the inner wall of the adapter ring 111. An external thread adapted to the internal thread is formed on the outer periphery of the bottom of the fixed base 121. The outer wall of the fixed base 121 and the inner wall of the adapter ring 111 are connected by the external and internal threads. A mounting groove 1211 is formed on one end face of the fixed base 121, and an internal thread is formed on the inner wall of the mounting groove 1211. A mounting ring 131 is provided on the side of the friction member 130 near the fixed base 121, and an external thread adapted to the internal thread is formed on the outer wall of the mounting ring 131. The mounting ring 131 is screwed into the mounting groove 1211, so that the fixed base 121 and the friction member 130 are detachably connected. A liquid flow channel 1212 for liquid flow is formed on the fixed base 121. A storage chamber 122 is formed on the other end face of the fixed base 121 and is internally connected to the liquid flow channel 1212. The first bellows 123 stores detergent. The first bellows 123 is disposed within the storage chamber 122 and its axis is vertically aligned. A release hole is formed on the top surface of the first bellows 123. A first return spring 124 is vertically installed inside the first bellows 123. When the first bellows 123 is compressed, its internal volume gradually decreases, and the first return spring 124 is gradually compressed, reducing the degree of deformation of the first bellows 123 and thus reducing the outflow of detergent. The detergent flows out from the release hole and flows through the liquid flow channel 1212, adhering to the friction member 130. When the first bellows 123 is no longer compressed, it spontaneously recovers its deformation. Simultaneously, the force of the first return spring 124 helps the first bellows 123 recover its deformation more quickly. The cleaning agent and water work together on the surface of the vessel, improving cleaning efficiency and effectiveness. Simultaneously, water and cleaning agent can be used to remove stains from the friction parts 130.

[0038] Preferably, a plurality of liquid flow channels 1212 are formed on the fixing base 121, each penetrating the top and bottom ends of the fixing base 121. This improves the efficiency of the cleaning agent flowing to the friction member 130.

[0039] Reference Figure 4 , Figure 5 and Figure 6The utensil cleaning tool also includes a second bellows 150, a second return spring 190, a first squeezing mechanism 160, and a second squeezing mechanism 170. The second bellows 150 stores cleaning agent inside. The second bellows 150 is located within the handle 110 and its axis is vertically aligned. The top end of the second bellows 150 is connected to the liquid flow channel 1212 via a first connector 181, a guide pipe 182, and a second connector 183. The second return spring 190 is vertically installed inside the second bellows 150. When the second bellows 150 is squeezed, its internal volume gradually decreases, and the second return spring 190 is gradually compressed, reducing the deformation of the second bellows 150 and thus reducing the outflow of cleaning agent. The cleaning agent flowing from the second bellows 150 flows sequentially through the first connector 181, the guide pipe 182, the second connector 183, and the liquid flow channel 1212 before being adsorbed onto the friction element 130. The detergent and water work together on the surface of the vessel, improving cleaning efficiency and effectiveness. Simultaneously, water and detergent can remove stains from the friction parts 130. Since the storage compartment 122 and handle 110 cannot undergo significant deformation, a first squeezing mechanism 160 is installed on the storage compartment 122, and a second squeezing mechanism 170 is installed on the handle 110. The human hand applies pressure to the first bellows 123 via the first squeezing mechanism 160, causing the bellows 123 to release detergent. The human hand applies pressure to the second bellows 150 via the second squeezing mechanism 170, causing the second bellows 150 to release detergent. It should be noted that when scrubbing the interior of ordinary vessels of moderate depth, the human hand applies pressure to the first bellows 123 via the first squeezing mechanism 160 to release detergent. When scrubbing the inside of deep or irregularly shaped containers, the human hand applies pressure to the second corrugated tube 150 through the second squeezing mechanism 170 to release the cleaning agent from the second corrugated tube 150. At this time, the first squeezing mechanism 160 and the first corrugated tube 123 do not participate in the work.

[0040] Preferably, a plurality of release holes are uniformly formed circumferentially on the top end of the first bellows 123 to improve the efficiency of releasing cleaning agent when the first bellows 123 is squeezed.

[0041] Preferably, the cleaning agent is a household cleaner.

[0042] In one embodiment, such as Figure 4 and Figure 5As shown, the first extrusion mechanism 160 includes a first extrusion plate 161, a first transmission rod 162, a first button 163, a third return spring 164, a third bellows 165, and a first bushing 166. The first extrusion plate 161 is disposed inside the storage chamber 122, with its bottom surface contacting the top end of the first bellows 123. The axis of the first transmission rod 162 is vertically arranged, with its bottom end fixedly connected to the top end of the first extrusion plate 161, and its top end extending through the storage chamber 122 to the outside of the storage chamber 122. The first button 163 is fixedly connected to the top end of the first transmission rod 162. The third return spring 164 is sleeved on the first transmission rod 162, with its bottom end fixedly connected to the top end of the storage chamber 122 and its top end fixedly connected to the bottom end of the first button 163. The third bellows 165 is sleeved around the third return spring 164, with its bottom end fixedly connected to the top end of the storage compartment 122 and its top end fixedly connected to the bottom end of the first button 163, thus protecting the third return spring 164 and providing waterproofing. When a human hand applies pressure to the first button 163, the pressure is transmitted through the first transmission rod 162 to the first compression plate 161, which then applies pressure to the first bellows 123. During this process, the third return spring 164 is gradually compressed. When the human hand is removed from the first button 163, the force of the third return spring 164 restoring its deformation drives the first button 163, the first transmission rod 162, and the first compression plate 161 to return to their original positions. The first bushing 166 is installed at the top of the storage compartment 122, allowing the first transmission rod 162 to pass through, serving as a guide. A first limiting protrusion 1621 is formed on the side wall of the first transmission rod 162. The first limiting protrusion 1621 can abut against the top of the storage compartment 122 to prevent the first transmission rod 162 from falling off the storage compartment 122.

[0043] In one embodiment, such as Figure 4 and Figure 6As shown, the second pressing mechanism 170 includes a second pressing plate 171, a second transmission rod 172, a second button 173, a fourth return spring 174, a fourth bellows 175, and a second bushing 176. The second pressing plate 171 is disposed inside the handle 110, with its bottom surface contacting the top end of the second bellows 150. The axis of the second transmission rod 172 is vertically oriented, with its bottom end fixedly connected to the top end of the second pressing plate 171, and its top end extending through the handle 110 to the outside of the handle 110. The second button 173 is fixedly connected to the top end of the second transmission rod 172. The fourth return spring 174 is sleeved on the second transmission rod 172, with its bottom end fixedly connected to the top end of the handle 110 and its top end fixedly connected to the bottom end of the second button 173. The fourth bellows 175 is sleeved outside the fourth return spring 174, with its bottom end fixedly connected to the top end of the handle 110 and its top end fixedly connected to the bottom end of the second button 173, thus protecting the fourth return spring 174 and providing waterproofing. When a human hand applies pressure to the second button 173, the pressure is transmitted through the second transmission rod 172 to the second compression plate 171, which then applies pressure to the second bellows 150. During this process, the fourth return spring 174 is gradually compressed. When the human hand is removed from the second button 173, the force of the fourth return spring 174 restoring its deformation drives the second button 173, the second transmission rod 172, and the second compression plate 171 to return to their original positions. The second bushing 176 is installed at the top of the handle 110, allowing the second transmission rod 172 to pass through and serving as a guide. A second limiting protrusion 1721 is formed on the side wall of the second transmission rod 172, which abuts against the top of the handle 110 to prevent the second transmission rod 172 from falling off the handle 110.

[0044] In some embodiments, the handle 110 comprises the following raw materials in weight percentages: 60%-80% polylactic acid (PLA), 20%-40% polybutylene succinate (PBS), 15%-20% mineral filler, and 5%-8% plasticizer. PLA, derived from corn starch, has well-defined degradability and high hardness, thus increasing the hardness of the handle 110. PBS is used to improve the flexibility and water resistance of the handle 110, compensating for the brittleness of PLA when exposed to water. Mineral filler improves the rigidity and heat resistance of the handle 110, preventing deformation and increasing reusability. Plasticizer improves the processing flowability of the PLA and PBS blend, preventing cracking during injection molding.

[0045] In some embodiments, the grippable support 120 comprises the following raw materials by weight percentage: 60%-80% polylactic acid (PLA), 20%-40% polybutylene succinate (PBS), 15%-20% mineral filler, and 5%-8% plasticizer. PLA, derived from corn starch, has well-defined degradability and high hardness, thus enhancing the hardness of the grippable support 120. PBS is used to improve the flexibility and water resistance of the grippable support 120, compensating for the embrittlement defect of PLA when exposed to water. Mineral filler improves the rigidity and heat resistance of the grippable support 120, preventing deformation and increasing reusability. Plasticizer improves the processing flowability of the PLA and PBS blend, preventing cracking during injection molding.

[0046] Preferably, the mineral filler is calcium carbonate or talc. Calcium carbonate is abundant and inexpensive. It has high whiteness, allowing for flexible formulation of products in various colors with minimal impact on the product's appearance. Its granular form minimizes its impact on the impact toughness of the handle 110 and the grippable support 120, ensuring high toughness for both components. Furthermore, calcium carbonate has good dispersibility, maintaining a smooth product appearance. Talc significantly improves the product's stiffness, dimensional stability, and heat resistance, offering superior reinforcing effects compared to calcium carbonate, resulting in higher wear resistance and corrosion resistance.

[0047] Preferably, the plasticizer is a citrate ester plasticizer. Compared to other types of plasticizers, it is essentially non-toxic and extremely safe. Its production and use processes have minimal environmental impact, making it relatively environmentally friendly. It exhibits outstanding thermal stability and safety, and good compatibility. Furthermore, it possesses properties such as cold resistance, light resistance, and water resistance, maintaining stable performance under various application environments, and is widely used in the food packaging field.

[0048] Preferably, the handle 110 further includes the following material by weight percentage: 0.1%-0.3% anti-hydrolysis agent. The grip support 120 further includes the following material by weight percentage: 0.1%-0.3% anti-hydrolysis agent. The anti-hydrolysis agent is beneficial to the underwater lifespan of the handle 110 and the grip support.

[0049] Preferably, the anti-hydrolysis agent is carbodiimide, which has higher anti-hydrolysis efficiency, optimal anti-hydrolysis effect, strong functional versatility, and combines repair performance with long-term protection. It is also relatively safe and environmentally friendly.

[0050] In some embodiments, the friction element 130 comprises the following raw materials by weight percentage: 60%-70% polypropylene fiber, 30%-40% bamboo fiber, 1%-3% coupling agent, and 0.5%-1% antibacterial agent. Polypropylene fiber, as a synthetic fiber, possesses high strength, high wear resistance, chemical stability, and resilience. It is resistant to oil stains and not easily deformed, making it suitable for removing stubborn stains such as burnt residue and rice grains from the surface of utensils. Bamboo fiber, as a natural cellulose material, possesses hydrophilicity, surface oleophilicity, antibacterial properties, and biodegradability. It can quickly absorb moisture and oil, improving cleaning power and reducing the amount of detergent used. Moreover, the antibacterial properties of bamboo fiber (containing bamboo quinone) can inhibit bacterial growth in humid environments, reducing the risk of secondary contamination of utensils. Simultaneously, the good toughness of bamboo fiber can reduce the wear rate of polypropylene fiber, indirectly reducing the release of microplastics. The coupling agent improves the bonding force at the interface between polypropylene fiber and bamboo fiber, reducing fiber shedding. The antibacterial agent compensates for the short antibacterial time of bamboo fiber, extending the antibacterial period. When used in combination, polypropylene fibers provide structural support and frictional cleaning force, while bamboo fibers enhance adsorption capacity and buffer friction, creating a synergistic effect of rigid cleaning and flexible adsorption. This helps reduce the number of scrubbing cycles and improves cleaning effectiveness. Compared to traditional nylon / steel wire materials, it is less likely to generate microplastic / micrometal pollution, reducing damage to the surface of utensils. Bamboo fiber is also biodegradable, reducing environmental pollution. Compared to using only bamboo fiber or bio-based materials such as corn starch, the friction component 130 has a certain degree of hardness, making the structure less prone to deformation, ensuring cleaning power, and extending service life. It simultaneously achieves antibacterial properties, environmental friendliness, cleaning effectiveness, and durability.

[0051] Preferably, the coupling agent is a silane-based coupling agent, which can not only achieve interfacial coupling through chemical reactions, but also has multiple functions such as crosslinking agent, wetting agent and dispersant.

[0052] Preferably, the antibacterial adjuvant is silver-loaded zeolite, which has a clear and efficient antibacterial mechanism, can take effect at low concentrations, has a wide antibacterial range, is harmless to the human body, and has no effect on the color of the product.

[0053] The implementation principle of this embodiment is as follows: When the adapter ring 111 is connected to the grippable support 120, the handle 110 is used for hand gripping, and the cleaning tool is suitable for scrubbing ordinary utensils with moderate depth. When the adapter ring 111 is disconnected from the grippable support 120, the grippable support 120 is used for hand gripping, reducing the space occupied by the utensil cleaning tool and improving its flexibility in confined spaces. This makes it suitable for scrubbing deeper or irregularly shaped utensils, and provides a better cleaning effect for these utensils. Thus, the versatility of the utensil cleaning tool is greatly improved. When the friction element 130 has been used for a period of time or too many times, it can be detached from the grippable support 120 for easy replacement.

[0054] Reference Figure 7 This application also discloses a method for manufacturing a utensil cleaning tool, comprising: S1. Pre-treat bamboo fiber.

[0055] In this step, pretreatment refers to alkalizing the bamboo fiber to remove pectin and improve the entanglement between the bamboo fiber and the polypropylene fiber.

[0056] S2. According to the formula, polypropylene fiber, coupling agent, antibacterial agent and pretreated bamboo fiber are blended by melt spinning process and then extruded to prepare friction part 130.

[0057] In this step, the use of melt spinning process is beneficial for the uniform distribution of bamboo fibers.

[0058] S3. According to the formula, polylactic acid, polybutylene succinate, mineral filler and plasticizer are mixed and injection molded using injection molding process to prepare the handle 110 / the gripable support 120.

[0059] S4. The surfaces of the handle 110 and the grippable support 120 are treated.

[0060] In this step, treating the surfaces of the handle 110 and the grip support 120 involves applying a hydrophobic layer to their surfaces. This hydrophobic layer can be applied by coating, brushing, or immersion. The hydrophobic coating blocks moisture penetration, preventing swelling of the handle 110 and grip support 120 during long-term use. The hydrophobic coating can be made of food-grade silicone, offering high safety and excellent water-blocking properties.

[0061] In some embodiments, during injection molding in step S3, 0.1%-0.3% of an anti-hydrolysis agent is added, which is beneficial to the underwater lifespan of the handle 110 and the grip support.

[0062] It should be noted that the gripping support 120 and the friction component 130 can be manufactured separately, and in use, the gripping support 120 and the friction component 130 can be assembled. Alternatively, the gripping support 120 and the friction component 130 can be manufactured simultaneously using injection molding. In this case, the gripping support 120 and the friction component 130 are not detachable. The injection molding temperature should be less than or equal to 180℃ to prevent carbonization of the bamboo fiber. Example

[0091] The following performance tests were conducted on the handles 110 and friction components 130 prepared in Examples 1-6 and Comparative Examples 1-2: Degradability test: Using ISO 14855, the product was mixed with compost inoculum and cultured in a controlled composting environment with a temperature of 58±2℃, humidity of 50%-55%, and sufficient oxygen. The amount of carbon dioxide released during the degradation process was measured, and the ratio of the actual release to the theoretical maximum release was calculated, which is the biodegradation rate. The test period was 180 days.

[0092] Hardness test: The surface indentation hardness was measured using a Shore hardness tester (Type A).

[0093] Flexibility test: ISO 527-2 is used to test the elongation of the material before fracture. Water resistance test: ISO 62 is used to immerse the product in water at 23°C for 24 hours and calculate the percentage increase in mass.

[0094] Rigidity test: Using ISO178, the elastic modulus is calculated through a three-point bending test to evaluate the resistance to bending deformation.

[0095] Heat resistance test: ISO 75 was used, measuring the temperature at which the material deforms by 1 mm under loads of 0.45 MPa / 1.82 MPa. Antibacterial property test: GB / T21510-2008 "Evaluation Method for Antibacterial Properties of Antibacterial Materials and Articles" was used. This standard is applicable to the antibacterial property testing of various antibacterial materials and articles, including plastics and metals.

[0097] Table 1 Performance test results Referring to Table 1, compared to Comparative Examples 1-3, the grip 110 / grip support obtained in Examples 1-3 exhibits better biodegradability, water resistance, heat resistance, antibacterial properties, and hydrolysis resistance. Hardness and rigidity are significantly improved, while possessing a certain degree of flexibility. The friction component 130 obtained in Examples 1-3 exhibits high hardness, rigidity, flexibility, heat resistance, antibacterial properties, and hydrolysis resistance. Simultaneously, it possesses a certain degree of biodegradability and hydrophilicity.

[0100] As can be seen from Examples 2, 3 and 6, silver-loaded zeolite significantly improves the antibacterial effect.

[0101] As can be seen from Examples 2, 7, 8 and 9, carbodiimide can slow down the degradation rate of the handle 110 / grip support to a certain extent, increase the hardness of the handle 110 / grip support, reduce the flexibility of the handle 110 / grip support, increase the stiffness and heat resistance of the handle 110 / grip support, significantly reduce the water absorption rate of the handle 110 / grip support, and significantly improve the hydrolysis resistance of the handle 110 / grip support.
