[0033] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0034] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0035] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0036] The following are some embodiments of the cleaning brush, brush head connector, and brush head provided in this application.

[0037] Please refer to Figure 1 and Figure 2 One embodiment of this application provides a cleaning brush 100. The cleaning brush 100 includes a brush head connector 1, a brush head 2, and a handle assembly 3. The brush head 2 has a soft structure to adapt to different shapes and structures of the objects being cleaned, enabling it to clean not only objects of conventional shapes but also objects with grids, curved surfaces, etc. (such as barbecue grills, barbecue ovens, etc.). The brush head 2 has a cleaning surface 21 as the working surface for cleaning operations. The brush head 2 is detachably connected to the brush head connector 1, and the brush head connector 1 is detachably connected to the handle assembly 3, achieving assembly and fixation of the three components. When using the cleaning brush 100 for cleaning operations, the user can hold the handle assembly 3 and move the brush head 2 across the surface of the object being cleaned to perform the cleaning operation. Specifically, the brush head 2 can be made of sponge, woven material, etc.

[0038] It's understandable that when cleaning brushes are used to clean barbecue grills, BBQ ovens, and other similar equipment, the brush heads are prone to wear and tear due to high temperatures and grease, requiring timely replacement. However, in existing cleaning brush products, the brush head and connector are usually machined as a single unit, making it difficult to disassemble and replace them separately. Therefore, once the brush head is worn out, both the brush head and connector must be replaced together.

[0039] In this embodiment, because the brush head 2 and the brush head connector 1 are detachably connected, the brush head 2 can be replaced separately when it is worn out, without having to replace the brush head connector 1 as well. This reduces material waste, lowers user costs, and aligns with the principles of energy conservation and environmental protection. Furthermore, since the brush head connector 1 and the handle assembly 3 are also detachably connected, when the brush head connector 1 is damaged, the user can replace it separately according to its condition.

[0040] In further embodiments of this application, please refer to Figure 1 , Figure 3 and Figure 4 The brush head connector 1 of the cleaning brush 100 specifically includes a fixing plate 11. The fixing plate 11 is located between the handle assembly 3 and the brush head. The fixing plate 11 has two opposing sides, one side of which is detachably connected to the brush head, and the side of the fixing plate 11 away from the brush head 2 is detachably connected to the handle assembly 3. The side of the brush head 2 away from the fixing plate 11 forms a cleaning surface 21, which is used to contact the surface of the object to be cleaned for cleaning operations.

[0041] By using a fixing plate 11 to connect the brush head 2 and the handle assembly 3, on the one hand, the contact area between the brush head connector 1 and the brush head 2 can be increased, making the connection of the brush head 2 more secure. On the other hand, the relatively small thickness of the fixing plate 11 can be used to reduce the space occupied in the thickness direction, which is beneficial to reducing the volume and weight of the cleaning brush 100.

[0042] In further embodiments of this application, please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 The fixing plate 11 and the brush head 2 are detachably connected by hooking the connecting hook surface 111 and the felt surface structure 22 together. Specifically, the fixing plate 11 has a connecting hook surface 111 on the side away from the handle assembly 3 (i.e., the side facing the brush head 2). The connecting hook surface 111 includes multiple hook structures 112, such as... Figure 6 and Figure 7In the example shown, multiple hook structures 112 are arranged on the surface of the fixing plate 11 to form a connecting hook surface 111. A felt surface structure 22 is provided on the side of the brush head 2 facing the fixing plate 11. The felt surface structure 22 can form a hook connection with the hook structures 112 on the connecting hook surface 111, thereby achieving a connection and fixation between the brush head 2 and the fixing plate 11. During assembly, simply align the felt surface structure 22 of the brush head 2 with the connecting hook surface 111 of the fixing plate 11 and press to complete the connection between the brush head 2 and the fixing plate 11. When the brush head 2 needs to be replaced, simply pull the brush head 2 away from the fixing plate 11 to separate the brush head 2 from the fixing plate 11, thus completing the disassembly of the brush head 2. By adopting the above connection method, a quick disassembly operation between the brush head 2 and the fixing plate 11 can be achieved. The operation is simple and convenient, requiring no professional tools, and can be completed by the user themselves.

[0043] Of course, the above is only one of the preferred connection methods for the brush head 2 in the cleaning brush 100 of this application. The brush head 2 can also adopt other connection methods. For example, in another embodiment, a groove can be provided on the side of the fixing plate 11 facing the brush head 2, and a corresponding connection structure (such as hook structure 112 or other connectors) can be provided on the inner side wall and / or bottom wall of the groove. During assembly, part of the structure of the brush head 2 extends into the groove of the fixing plate 11 and forms a connection with the connection structure in the groove, which can also achieve the connection and fixation between the brush head 2 and the fixing plate 11.

[0044] In further embodiments of this application, please refer to Figure 5 and Figure 6 The brush head connector 1 and the handle assembly 3 are connected via a snap-fit ​​mechanism. A first snap-fit ​​element is located on the brush head connector 1 near the handle assembly 3, and correspondingly, a second snap-fit ​​element is located on the handle assembly 3 near the brush head connector 1. The second snap-fit ​​element can be locked in place with the first snap-fit ​​element. One of the first and second snap-fit ​​elements includes a snap-button structure 1131, and the other includes a slot structure 321 adapted to the snap-button structure 1131. Figure 6 In the example, the first snap-fit ​​component includes a snap-fit ​​structure 1131, and the second snap-fit ​​component includes a slot structure 321. During assembly, the snap-fit ​​structure 1131 extends into the slot structure 321 and forms a snap-fit ​​engagement with it. A portion of the snap-fit ​​structure 1131 is incorporated outside the slot structure 321, forming a pressing operation part 1132 to facilitate pressing by the user. It can be understood that pressing the pressing operation part 1132 can change the shape of the snap-fit ​​structure 1131 (e.g., elastic deformation), thereby changing the engagement state between the snap-fit ​​structure 1131 and the slot structure 321, thus achieving a snap-fit ​​or contact-locking operation between the snap-fit ​​structure 1131 and the slot structure 321.

[0045] For example, such as Figure 6 , Figure 7 and Figure 9 In the example, the brush head connector 1 takes the form of a fixed plate 11, and the snap structure 1131 can take the form of a similar V-shaped or U-shaped elastic structure as shown in the figure, that is, it includes an inner plate and an outer plate that are connected to each other, wherein the inner plate is connected to the fixed plate 11, and the outer plate has a corresponding limiting protrusion; correspondingly, the slot structure 321 of the handle assembly 3 is also provided with a limiting baffle that matches the limiting protrusion. When the outer plate of the snap fastener structure 1131 is pressed, the outer plate moves towards the fixing plate 11, causing the limiting protrusion on the outer plate to misalign with the limiting baffle in the slot structure 321. At this time, the fixing plate 11 is pushed towards the handle assembly 3, allowing the snap fastener structure 1131 to extend into the slot structure 321. Once the snap fastener structure 1131 reaches the engaging position within the slot structure 321, it contacts the pressing of the outer plate. Under elastic force, the outer plate springs away from the fixing plate 11, causing the limiting protrusion on the outer plate to engage with the limiting baffle in the slot structure 321. The snap fastener structure 1131 and the slot structure 321 then enter a engaged state. When the outer plate of the snap fastener structure 1131 is pressed again, the engaged state ends. At this time, the fixing plate 11 is pulled away from the handle assembly 3, allowing for the removal of the fixing plate 11.

[0046] It should be noted that in practical applications, multiple sets of snap fastener structures 1131 and slot structures 321 can be set according to specific assembly requirements, or alternatively, as shown in the following example... Figure 8 and Figure 9 In the example shown, the first snap-fit ​​component includes a snap-fit ​​structure 1131 and a snap-fit ​​protrusion structure 1133, and the second snap-fit ​​component on the handle assembly 3 includes a slot structure 321 and a recess structure. Specifically, on opposite ends of the fixing plate 11, a snap-fit ​​structure 1131 is provided at one end and a snap-fit ​​protrusion structure 1133 is provided at the other end. Correspondingly, the handle assembly 3 has a slot structure 321 adapted to the snap-fit ​​structure 1131 and a recess structure adapted to the snap-fit ​​protrusion structure 1133 at the corresponding positions on the fixing plate 11. During assembly, the snap-fit ​​protrusion structure 1133 on the fixing plate 11 can be inserted horizontally into the corresponding recess structure first, and then the snap-fit ​​structure 1131 can be pressed and inserted into the corresponding slot structure 321 to form a snap-fit. The number and position of the snap-fit ​​structure 1131 and the snap-fit ​​protrusion structure 1133 are not limited to the example shown in the figure, and can be set according to specific assembly requirements.

[0047] Additionally, it should be noted that, depending on the specific assembly requirements, the specific forms of the first and second snap-fit ​​components in the above embodiments can also be interchanged. That is, the first snap-fit ​​component can be configured to include a slot structure 321, and the second snap-fit ​​component can be configured to include a snap-fit ​​structure 1131, which can also achieve the effect of mutual snap-fit ​​and fixation. This will not be elaborated further here.

[0048] In another embodiment of this application, a first snap-fit ​​member is provided on the brush head connector 1 of the cleaning brush 100 near the handle assembly 3. Correspondingly, a second snap-fit ​​member is provided on the handle assembly 3 near the brush head connector 1. The second snap-fit ​​member engages with the first snap-fit ​​member to fix the connection between the brush head connector 1 and the handle assembly 3. The brush head connector 1 can be disassembled by operating the first snap-fit ​​member or the second snap-fit ​​member to engage. The brush head 2 has a corresponding groove on the side facing the brush head connector 1. When the brush head 2, brush head connector 1, and handle assembly 3 are assembled, parts of the brush head connector 1 and handle assembly 3 are located within the groove of the brush head 2. This allows the sidewall of the groove in the brush head 2 to cover the first and second snap-fit ​​components, creating a hidden design. This not only improves the appearance of the cleaning brush 100 but also provides some protection for the brush head connector 1, the first snap-fit ​​component, the second snap-fit ​​component, and the handle assembly 3 at certain locations (where the brush head connector 1 is connected), further reducing the possibility of damage to these components. Alternatively, the brush head 2 can be designed without the groove, using only its own volume to cover the first and second snap-fit ​​components, creating a hidden design. This not only improves the appearance of the cleaning brush 100 but also allows for quick and easy disassembly of the brush head connector 1 after removing the brush head 2.

[0049] In further embodiments of this application, please refer to Figure 1 and Figure 2 The handle assembly 3 of the cleaning brush 100 includes a main body 31, a handle connector 32, and a handle 33. The handle connector 32 is located at one end of the main body 31, and the handle 33 is located at the other end of the main body 31 away from the handle connector 32. The handle connector 32 is detachably connected to the brush head connector 1, so that the handle assembly 3 is integrated with the brush head connector 1 and the brush head 2. The handle 33 is designed for easy gripping during use. Depending on the specific application of the cleaning brush 100, the main body 31 can be set to an appropriate length to maintain a suitable distance between the user and the object being cleaned.

[0050] In one specific implementation, such as Figure 2 and Figure 10 In the example shown, the main rod 31 is inclined relative to the handle connection 32, forming a first angle α between the main rod 31 and the handle connection 32. This first angle α is set within the range of 100° to 150°, and preferably, 120°. This angle setting optimizes the force transmission process, making the inclination of the main rod 31 more ergonomic, easier for the user to operate, and requiring less effort from the user.

[0051] In another specific implementation, such as Figure 2 and Figure 10 In the example shown, the handle portion 33 extends away from the handle connection portion 32 relative to the main body 31, and the extending direction of the handle portion 33 forms a second angle b with the cleaning surface 21 of the brush head 2. The second angle b is set between -20° and +20°. Figure 10 Taking the state shown as an example, when the cleaning surface 21 of the brush head 2 is in a horizontal state, the handle 33 can be tilted upward or downward relative to the horizontal surface at an angle of up to 20°. Preferably, the extension direction of the handle 33 is parallel to the cleaning surface 21 of the brush head 2, that is, the second angle b is 0°. At this time, when the user holds the handle 33 to perform cleaning operations, the direction of force transmission can be consistent with the direction of movement of the cleaning surface 21 of the brush head 2, making the operation more convenient.

[0052] In further embodiments of this application, please refer to Figure 1 and Figure 2 The handle assembly 3 also includes a gripping protrusion structure 34. The gripping protrusion structure 34 is located on the main body 31 near the handle connection part 32. When the user is cleaning, he / she can hold the handle part 33 with one hand and the gripping protrusion structure 34 with the other hand, so as to carry out the operation with both hands. This makes the cleaning operation more convenient and can also shorten the lever arm of the main body 31, thereby improving the problem of the excessively long lever arm of single-handed operation, which makes the operation more strenuous.

[0053] In one specific implementation, such as Figure 2 and Figure 10 In the example shown, the protruding direction of the grip protrusion structure 34 relative to the main rod 31 forms a third angle c with the extending direction of the main rod 31 itself, and the third angle c is set within the range of 90° to 120°. When the third angle c is 90°, the grip protrusion structure 34 is perpendicular to the main rod 31; when the third angle c is greater than 90° and less than or equal to 120°, the grip protrusion structure 34 is inclined relative to the main rod 31 in a direction away from the handle connection portion 32. Through the above angle setting, the grip protrusion structure 34 can be more ergonomically designed, making it easier for users to hold and perform cleaning operations.

[0054] It should be noted that the location of the hand-grip protrusion structure 34 is not limited to the position shown in the example. Figure 1 The image shows the upper part of the main rod 31. Alternatively, the hand grip protrusion 34 can be placed on the side or below the main rod 31, depending on the specific usage requirements. This will not be elaborated further here.

[0055] In further embodiments of this application, please refer to Figure 1 and Figure 2The handle assembly 3 of the cleaning brush 100 also includes a scraper structure 35. The scraper structure 35 is disposed on the handle connection part 32 and located at the end away from the main body 31. That is, the scraper structure 35 and the main body 31 are respectively connected to opposite ends of the handle connection part 32. Thus, when the user operates the brush, the scraper structure 35 can be moved by pushing the main body 31 to scrape the dirt on the surface of the object being cleaned. This is especially suitable for cleaning thick dirt.

[0056] Please refer to Figures 1 to 10 In one embodiment of this application, a cleaning brush 100 is provided, including a brush head connector 1, a brush head 2, and a handle assembly 3.

[0057] The handle assembly 3 includes a main body 31, a handle connecting part 32, a handrail part 33, a grip protrusion structure 34, and a scraper structure 35. The handle connecting part 32 is located at one end of the main body 31, and the handrail part 33 is located at the other end of the main body 31 away from the handle connecting part 32. The grip protrusion structure 34 is located on the main body 31 near the handle connecting part 32. The scraper structure 35 is located on the handle connecting part 32, and the scraper structure 35 and the main body 31 are respectively connected to opposite ends of the handle connecting part 32. The main body 31 is inclined relative to the handle connecting part 32, forming a first angle α between the main body 31 and the handle connecting part 32. The first angle α is set in the range of 100° to 150°, preferably 120°. The handle portion 33 extends away from the handle connection portion 32 relative to the main body 31, and the extension direction of the handle portion 33 forms a second angle b with the cleaning surface 21 of the brush head 2. The second angle b is set between -20° and +20°, preferably 0°, that is, the extension direction of the handle portion 33 is parallel to the cleaning surface 21 of the brush head 2. The grip protrusion structure 34 forms a third angle c with the protrusion direction of the main body 31 relative to the extension direction of the main body 31, and the third angle c is set within the angle range of 90° to 120°. When the third angle c is 90°, the grip protrusion structure 34 is set perpendicular to the main body 31; when the third angle c is greater than 90° and less than or equal to 120°, the grip protrusion structure 34 is set inclined away from the handle connection portion 32 relative to the main body 31.

[0058] The brush head connector 1 specifically includes a fixing plate 11. The fixing plate 11 is located between the handle connector 32 and the brush head 2. The fixing plate 11 has two opposing sides, one facing the brush head 2 and the other facing the handle connector 32. The side of the fixing plate 11 facing the handle connector 32 is provided with multiple intersecting reinforcing plates 114 to improve the strength of the fixing plate 11. The side of the fixing plate 11 facing the brush head 2 is provided with a connecting hook surface 111, which specifically includes multiple hook structures 112, such as... Figure 6 and Figure 7 In the example shown, multiple hook structures 112 are regularly arranged on the surface of the fixing plate 11 to form a connecting hook surface 111. A felt surface structure 22 is provided on the side of the brush head 2 facing the fixing plate 11. The felt surface structure 22 can form a hook connection with the hook structures 112 on the connecting hook surface 111 to achieve connection and fixation between the brush head 2 and the fixing plate 11. The brush head 2 uses a soft structure, such as a sponge or woven material. The side of the brush head 2 away from the fixing plate 11 forms a cleaning surface 21, which contacts the surface of the object being cleaned for cleaning. During assembly, simply align the felt surface structure 22 of the brush head 2 with the connecting hook surface 111 of the fixing plate 11 and press to complete the connection between the brush head 2 and the fixing plate 11. When the brush head 2 needs to be replaced, simply pull the entire brush head 2 away from the fixing plate 11 to separate the brush head 2 from the fixing plate 11, thus completing the disassembly of the brush head 2.

[0059] The fixing plate 11 is provided with a first snap-fit ​​component, and correspondingly, the handle connecting part 32 is provided with a second snap-fit ​​component, which can be snapped and fixed with the first snap-fit ​​component. For example, Figures 6 to 9 In the example shown, the first snap-fit ​​component includes a snap-fit ​​structure 1131 and two snap-fit ​​protrusions 1133, with the snap-fit ​​structure 1131 and the snap-fit ​​protrusions 1133 located at opposite ends of the fixing plate 11; the second snap-fit ​​component includes a slot structure 321 and two slot structures, with the slot structure 321 corresponding to the snap-fit ​​structure 1131 and the two slot structures corresponding to the two snap-fit ​​protrusions 1133. Specifically, the snap-fit ​​structure 1131 can adopt the following... Figure 7The V-shaped elastic structure shown includes an inner plate and an outer plate connected to each other. The inner plate is connected to the fixed plate 11. The outer plate has a corresponding limiting protrusion on the side away from the fixed plate 11, and the end of the outer plate away from the connection point with the inner plate forms a pressing operation part 1132. The snap structure 1131 protrudes as a whole towards the side near the handle connection part 32. Correspondingly, the slot structure 321 on the handle connection part 32 is also provided with a limiting baffle adapted to the limiting protrusion. Both snap protrusion structures 1133 protrude laterally relative to the fixed plate 11, and the slot structure on the handle connection part 32 corresponds to the snap protrusion structures 1133. During assembly, the snap protrusion 1133 on the fixing plate 11 can be inserted horizontally into the corresponding slot structure first, and then the outer plate of the snap fastener 1131 can be pressed and inserted into the corresponding slot structure 321 so that the snap fastener 1131 extends into the snap-fit ​​position in the slot structure 321. After pressing, the limiting protrusion on the outer plate and the limiting baffle in the slot structure 321 can form a snap-fit ​​engagement, so that the snap fastener 1131 and the slot structure 321 enter the snap-fit ​​state, and the pressing operation part 1132 of the snap fastener 1131 is exposed outside the slot structure 321 to facilitate the user's pressing operation. During disassembly, press the outer plate of the snap fastener structure 1131 again to disengage the snap fastener structure 1131 from the slot structure 321. Then, pull the end of the fixing plate 11 with the snap fastener structure 1131 away from the handle connection part 32. Then, pull the fixing plate 11 as a whole laterally to pull the protruding structure 1133 out from the corresponding slot structure, thus achieving the disassembly of the fixing plate 11.

[0060] The cleaning brush 100 in this embodiment allows for quick disassembly and detachment of the brush head 2, fixing plate 11, and handle assembly 3. The operation is simple and convenient, requiring no specialized tools; users can operate it themselves. Furthermore, during cleaning, the user can hold the handle 33 with one hand and the grip protrusion 34 with the other, enabling coordinated two-handed operation. The angle of the handle assembly 3 is also more ergonomic, making operation more effortless. Both the brush head 2 and the brush head connector 1 are replaceable individually. When the brush head 2 is worn, it can be replaced alone without replacing the brush head connector 1. Similarly, if the brush head connector 1 is damaged, the user can replace it separately, reducing material waste and lowering replacement costs.

[0061] In summary, the cleaning brush 100 of this embodiment can improve the convenience for the operator, and the quick-release structure allows for rapid disassembly and replacement of cleaning consumables; by replacing consumables, the service life of the entire cleaning brush 100 product can be increased; the cost-effectiveness of the product is improved, and more cleaning scenarios can be covered by changing different brush heads 2.
