Description
Technical Field
[0001] This utility model belongs to the field of cleaning products technology, and in particular relates to a rotating pot brush. Background Technology
[0002] In daily life, cookware is often heavily soiled with grease, making cleaning quite tedious. On one hand, the angle between the handle and the brush head is usually fixed, making it difficult for users to clean cookware of different shapes, sizes, and placements in a comfortable posture. This leads to low cleaning efficiency and hand fatigue. For example, when cleaning the interior of deeper cookware, a fixed-angle brush head may not effectively reach the bottom or the outer edges of the cookware, often preventing the bristles from fully contacting the stains and resulting in poor cleaning. On the other hand, the use of cleaning solutions also has shortcomings. Many cookware brushes lack dedicated cleaning solution delivery and storage devices, requiring users to frequently dip the brush in cleaning solution. This is not only inconvenient but also wastes cleaning solution and stains the countertop. Utility Model Content
[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a rotating pot brush to meet the needs of users.
[0004] To achieve the above objectives, this utility model provides a rotating pot brush, including...
[0005] The handle includes a liquid chamber disposed along its axial direction, the liquid chamber being adapted to store cleaning fluid.
[0006] The brush head includes a carrier and bristles, the carrier including a liquid outlet.
[0007] A brush holder includes a first brush holder adapted to connect to the handle and a second brush holder adapted to connect to the brush head. The first brush holder and the second brush holder are adapted to rotate about a first axis to adjust the angle of the handle relative to the brush head. The first axis intersects the carrier to form a rotation angle β, which does not include 90°.
[0008] The first brush holder includes a first flow channel adapted to communicate with the liquid cavity, and the second brush holder includes a second flow channel adapted to communicate with the liquid outlet. The first flow channel and the second flow channel are in communication and are adapted to rotate around the first axis.
[0009] Preferably, the first brush holder and the second brush holder cooperate to form a hemispherical structure, the carrier is adapted to close the second brush holder and form the bottom surface of the hemispherical structure, and the liquid outlet is located in the center of the carrier.
[0010] The first brush holder includes a first rotating surface, and the second brush holder includes a second rotating surface. The first rotating surface and the second rotating surface are facing each other and are arranged parallel to each other. The first axis is adapted to pass through the center of the first rotating surface and the center of the second rotating surface, and the first axis is arranged perpendicular to the first rotating surface and the second rotating surface.
[0011] Preferably, the included rotation angle β is between 70° and 45°.
[0012] Preferably, the first rotating surface includes a plurality of positioning grooves, and the second rotating surface includes at least one positioning protrusion. The positioning protrusion is adapted to be engaged with the positioning grooves one by one to achieve gear adjustment. When the positioning protrusion is engaged with one of the positioning grooves, the handle is set perpendicular to the carrier.
[0013] The positioning groove on the first rotating surface and the positioning protrusion on the second rotating surface work together to achieve gear adjustment. When the positioning protrusion engages with the positioning groove, the handle is set perpendicular to the carrier, allowing users to select different angle gears according to their own habits and cleaning scenarios, greatly enhancing the flexibility and adaptability of using the pot brush.
[0014] Preferably, the second rotating surface includes two symmetrically arranged positioning protrusions.
[0015] Preferably, the second rotating surface includes an arc-shaped strip, a first arc-shaped groove and a second arc-shaped groove disposed on both radial sides of the arc-shaped strip, the positioning protrusion being disposed in the middle of the arc-shaped strip, and the first arc-shaped groove and the second arc-shaped groove being adapted to provide space for deformation of the arc-shaped strip.
[0016] Preferably, the first brush holder includes a first tube adapted to form a portion of the first flow channel, and the second brush holder includes a second tube adapted to form at least a portion of the second flow channel. The first tube is disposed along the first axial direction, and the second tube is disposed along the first axial direction, wherein:
[0017] At least a portion of the first tube extends outward from the center of the first rotating surface, and the second tube extends inward from the center of the second rotating surface; or, the first tube extends inward from the center of the first rotating surface, and at least a portion of the second tube extends outward from the center of the second rotating surface.
[0018] Preferably, the first tube or the second tube is fitted with a sealing ring.
[0019] Preferably, one of the first brush holder and the second brush holder includes a plurality of cantilever male buckles, which extend outward from the first rotating surface or the second rotating surface along the first axis l1 and are evenly distributed circumferentially about the first axis l1. The other of the first brush holder and the second brush holder includes a circular female buckle adapted to engage with the cantilever male buckle.
[0020] The cantilever male buckle and the circular female buckle are positioned and engaged along the first axis l1, which restricts the separation of the first brush holder and the second brush holder along the first axis l1, while allowing the first brush holder and the second brush head to rotate around the first axis.
[0021] Preferably, the handle includes a hollow structure adapted to form the liquid cavity, and the handle forms a third tube adapted to communicate with the liquid cavity. The first brush holder includes a flexible tube adapted to form part of the first flow channel. One end of the flexible tube is connected to the first tube, and the other end of the flexible tube is connected to the third tube. The flexible tube is shaped into an S-shape, which lengthens the flow path of the cleaning fluid. Compared to a straight pipe, the liquid needs to go through more turns and bends in the S-shaped flexible tube, which increases the flow time of the liquid in the flexible tube. The process of constantly changing the flow rate and direction makes the flow of the cleaning fluid in the flexible tube more stable, avoiding the cleaning fluid from directly impacting the downstream flow channel at a high speed, and helping to control the outflow of the cleaning fluid more evenly.
[0022] Preferably, the handle includes a hollow structure adapted to form the liquid cavity, the handle has an open end facing the first brush holder, the first brush holder includes a fourth tube adapted to connect the open end, the first flow channel includes the first flow channel, the fourth tube, and a fifth tube adapted to connect the first tube and the fourth tube, the fifth tube gradually contracting in the direction of liquid flow.
[0023] Preferably, the fifth tube is formed by obliquely cutting a circular tube with an arc surface, the arc surface tending to bulge outwards, or the cross-section of the arc surface is bow-shaped. This special arc surface structure guides the flow of the cleaning fluid. As the cleaning fluid flows across the arc surface, the contact area and angle between the liquid and the arc surface constantly change, making the flow trajectory of the liquid more complex and increasing the friction and interaction between the liquid and the tube wall. This complex flow process consumes some of the kinetic energy of the cleaning fluid, reducing its flow velocity, thereby achieving a slow flow and helping to make the cleaning fluid more evenly distributed when flowing out of the fifth tube, improving the stability and uniformity of the outflow.
[0024] As a preferred option, at least one of the following conditions must be met:
[0025] The handle includes a resilient button, and the second flow channel or the liquid outlet includes a one-way valve. The resilient button is adapted to change the air pressure in the liquid chamber by deformation, thereby driving the cleaning fluid to squeeze the one-way valve to deform, and the cleaning fluid flows out through the opening, which is convenient to control.
[0026] The handle is provided with a hanging part at the end away from the first brush holder. The handle can be rotated so that the brush holder, handle and brush head are arranged in a straight line, which saves space and facilitates hanging.
[0027] The handle includes a filling port and a filling plug adapted to close the filling port;
[0028] The handle is made of a visible material, making it easy to observe the remaining cleaning fluid and determine whether the cleaning is complete.
[0029] The beneficial effects of this utility model are:
[0030] First, the first and second brush holders can rotate around the first axis l1, with the included rotation angle β not exceeding 90° and further limited to between 70° and 45°. This design allows the angle of the handle relative to the brush head to be flexibly adjusted according to actual cleaning needs. When cleaning curved pot bottoms, the handle can be adjusted to a suitable angle so that the bristles closely conform to the curve of the pot bottom, effectively removing stubborn stains. When cleaning straight-walled cookware, the angle can also be easily changed, making cleaning more efficient while reducing hand fatigue for the user.
[0031] Second, the first flow channel of the first brush holder is connected to the second flow channel of the second brush holder and can rotate around the first axis l1, ensuring the continuity and stability of liquid output during angle adjustment. Simultaneously, the ingenious arrangement of the first and second tubes and the use of sealing rings further ensure that the liquid will not leak, allowing the cleaning fluid to flow out evenly and smoothly from the outlet, thus improving cleaning efficiency.
[0032] Third, the S-shaped hose or special arc-shaped structure acts as a slow flow mechanism during the release of the cleaning solution, allowing the cleaning solution to be evenly released to the areas that need cleaning according to actual cleaning needs. This avoids overuse of the cleaning solution, enables precise control of the amount of cleaning solution released, and also avoids splashing caused by the impact force of excessive flow rate, making the cleaning process cleaner and tidier.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0042] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.
[0043] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0044] Example 1
[0045] like Figure 1-6A rotating pot brush includes a handle 1, a brush head 2, and a brush holder 5. The handle 1 includes a liquid cavity 11 arranged along its axial direction, adapted to store cleaning fluid. The brush head 2 includes a carrier 21 and bristles 22. The carrier 21 is flat and includes a liquid outlet 211. The central axis of the handle 1 is defined as a second axis l2. The brush holder 5 includes a first brush holder 3 adapted to connect the handle 1 and a second brush holder 4 adapted to mount the brush head 2. The first brush holder 3 and the second brush holder 4 cooperate to form a hemispherical structure. The carrier 21 is adapted to close the second brush holder 4 and form the bottom surface of the hemispherical structure. One end of the bristles 22 is fixed to the carrier 21, and the liquid outlet 211 is located at the center of the carrier 21. The first brush holder 3 includes a first rotating surface 31, and the second brush holder 4 includes a second rotating surface 41. The first rotating surface 31 and the second rotating surface 41 are arranged facing each other and parallel to each other. The first brush holder 3 and the second brush holder 4 are adapted to rotate about a first axis l1. The first axis l1 is adapted to pass through the center of the first rotating surface 31 and the center of the second rotating surface 41, and the first axis l1 is perpendicular to the first rotating surface 31 and the second rotating surface 41. The first axis l1 intersects the carrier 21 to form a rotation angle β of 65°, and the second axis l2 intersects the first axis l1 to form a rotation angle α of 25°. The first brush holder 3 includes a first flow channel 32 adapted to communicate with the liquid cavity 11, and the second brush holder 4 includes a second flow channel 42 adapted to communicate with the liquid outlet 211. The first flow channel 32 and the second flow channel 42 are connected and adapted to rotate around the first axis l1.
[0046] In this embodiment, the first rotating surface 31 includes six positioning grooves 311, and the second rotating surface 41 includes two symmetrically arranged positioning protrusions 411. The positioning protrusions 411 are adapted to engage with the positioning grooves 311 one by one to achieve gear adjustment. When a positioning protrusion 411 engages with one of the positioning grooves 311, the handle 1 is perpendicular to the carrier 21. Specifically, the second rotating surface 41 includes an arc-shaped strip 412, a first arc-shaped groove 413 and a second arc-shaped groove 414 disposed on both radially sides of the arc-shaped strip 412, and the positioning protrusions 411 are disposed in the middle of the arc-shaped strip 412. The first arc-shaped groove 413 and the second arc-shaped groove 414 are adapted to provide space for deformation of the arc-shaped strip 412. The positioning grooves 311 of the first rotating surface 31 and the positioning protrusions 411 of the second rotating surface 41 cooperate with each other to achieve gear adjustment. When the positioning protrusion 411 is engaged in the positioning groove 311, the handle 1 is set perpendicular to the carrier 21. Users can select different angle settings according to their own habits and cleaning scenarios, which greatly enhances the flexibility and adaptability of using the pot brush.
[0047] In this embodiment, the handle 1 includes a hollow structure suitable for forming the liquid cavity 11, and the end of the handle 1 facing the first brush holder 3 has an open end. The first brush holder 3 includes a first tube 321, a fifth tube 323, and a fourth tube 322 connected in sequence to form a first flow channel 32. The fourth tube 322 is screwed onto the open end, and the fifth tube 323 gradually contracts in the direction of liquid flow. The second brush holder 4 includes a second tube suitable for forming a second flow channel 42. The first tube 321 extends outward from the center of the first rotating surface 31, and the second tube extends inward from the center of the second rotating surface 41. The first tube 321 is arranged along the first axis l1, and the second tube is arranged along the first axis l1. The first tube 321 is inserted into the second tube, and a sealing ring 325 is fitted onto the first tube 321. The sealing ring 325 ensures that the entire cleaning liquid outflow pipe remains sealed and airtight when the first brush holder 3 and the second brush holder 4 rotate relative to each other to adjust the angle.
[0048] In this embodiment, the fifth tube 323 is formed by obliquely cutting a circular tube with an arc surface 3231, which tends to bulge outwards. The special structure of the arc surface 3231 guides the flow of the cleaning fluid. As the cleaning fluid flows through the arc surface 3231, the contact area and angle between the liquid and the arc surface 3231 continuously change, making the flow trajectory of the liquid more complex and increasing the friction and interaction between the liquid and the tube wall. This complex flow process consumes some of the kinetic energy of the cleaning fluid, reducing its flow velocity, thereby achieving a slow flow and helping to make the cleaning fluid more evenly distributed when flowing out of the fifth tube 323, improving the stability and uniformity of the outflow.
[0049] In this embodiment, the first brush holder 3 includes a plurality of cantilever male buckles 33, which extend outward from the first rotating surface 31 along the first axis l1. The cantilever male buckles 33 are evenly distributed circumferentially around the first tube body 321 about the first axis l1. The second brush holder 4 includes a circular female buckle 43 adapted to engage with the cantilever male buckles 33. The cantilever male buckles 33 and the circular female buckles 43 are engaged along the first axis l1 to limit the separation of the first brush holder 3 and the second brush holder 4 along the first axis l1, while allowing the first brush holder 3 and the second brush head 2 to rotate around the first axis.
[0050] In this embodiment, the handle 1 includes a resilient button 13, and the second flow channel 42 includes a one-way valve 421 made of silicone material. The one-way valve 421 is adapted to prevent liquid leakage and remains closed when the resilient button 13 is not pressed. The resilient button 13 is adapted to change the air pressure in the liquid chamber 11 by deformation, thereby driving the cleaning fluid to squeeze the one-way valve 421 to deform, and the cleaning fluid flows out through the opening, which is convenient to control. Specifically: when the user presses the resilient button 13, the resilient button 13 deforms and compresses the air and liquid in the liquid chamber 11. After the pressure in the liquid chamber 11 increases, the liquid passes through the first flow channel 32 and the second flow channel 42 through the one-way valve 421 and finally flows out from the outlet 311. When the user releases the resilient button 13, the resilient button 13 returns to its original shape, and a negative pressure is formed in the liquid chamber 11. Under the action of negative pressure, external air enters the liquid chamber 11 through the one-way valve 421, balancing the air pressure inside and outside the liquid chamber 11, while preventing liquid backflow.
[0051] In this embodiment, the handle 1 is a hollow structure with both ends open. A hanging part 12 is screwed onto the end of the handle 1 furthest from the first brush holder 3. The handle 1 can be rotated so that the brush holder 5, handle 1, and brush head 2 are aligned in a straight line, saving space and facilitating hanging. Cleaning fluid can also be poured in from either end. The handle 1 is made of a visible material, allowing the user to easily observe the remaining cleaning fluid level, add more fluid as needed, and determine whether the pot brush needs cleaning, thus maintaining the cleanliness of the pot brush, extending its lifespan, and improving the overall cleaning experience for the user.
[0052] Example 2
[0053] like Figure 7 The rotating brush described herein differs from Embodiment 1 in that the handle 1 includes a hollow structure suitable for forming a liquid cavity 11, and the handle 1 forms a third tube 14 suitable for communicating with the liquid cavity 11. The first brush holder 3 includes a flexible tube 324 suitable for forming a first flow channel 32 and a first tube 321. The first tube 321 extends from the center of the first rotating surface 31 to both ends. Part of the first tube 321 is inserted and communicated with a second tube, and part of the first tube 321 is connected to one end of the flexible tube 324. The third tube 14 is connected to the other end of the flexible tube 324. The flexible tube 324 is shaped into an S-shape, which makes the flow path of the cleaning liquid longer. Compared with a straight pipe, the liquid needs to go through more turns and bends in the S-shaped flexible tube 324, which increases the flow time of the liquid in the flexible tube 324. The process of constantly changing the flow rate and direction makes the flow of the cleaning liquid in the flexible tube 324 more stable, avoiding the cleaning liquid from directly impacting the downstream flow channel at a high speed, and helping to control the outflow of the cleaning liquid more evenly.
[0054] In this embodiment, the handle 1 includes a fourth tube 322, which is inserted into the open end of the handle 1 and guides the third tube 14 to be inserted into the hose 324. The third tube 14 is adapted to extend into the fourth tube 322.
[0055] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
