An adjustable deformable brush

Abstract

An adjustable and deformable brush includes a brush body and a cleaning section on the surface of the brush body. The brush body has a handle at its upper end. The brush body is bendable and deformable, and an adjusting rod is located at its lower end. The adjusting rod can move relative to the handle, causing the brush body to bend and deform, increasing its outer diameter, when the two ends of the brush body are close together, or to straighten and shrink its outer diameter when the two ends of the brush body are far apart. A locking structure is provided between the adjusting rod and the handle, including a locking head and a locking position. The locking head and locking position are respectively located on the adjusting rod and the handle. The movement of the adjusting rod relative to the handle is limited by the locking head entering the locking position—restraining or locking the bending and deforming state of the brush body; the relative movement is allowed when the locking head exits the locking position. Because the brush of this invention can be adjusted to clean objects of different sizes, it provides good cleaning results and saves time and effort. The bending and deforming of the brush creates multi-directional cleaning sections, making cleaning the cavity simple and convenient.

Description

Technical Field

[0001] This invention relates to a brush. Background Technology

[0002] Currently, there are many types of brushes on the market, such as cup brushes and shoe brushes. The brush includes a brush body and bristles on the surface of the brush body. The brush can clean objects through the bristles. However, since the objects being cleaned are of different sizes, cleaning their inner cavities requires brushes with different outer bristle profiles. If the brushes are not matched, the cleaning effect will be poor and it will be time-consuming and laborious. Summary of the Invention

[0003] One object of the present invention is to provide an adjustable-deformation brush that solves the above-mentioned problems.

[0004] To achieve the above-mentioned objectives, the present invention is implemented through the following technical solution: an adjustable and deformable brush, comprising a brush body and a cleaning part disposed on the surface of the brush body, wherein the upper end of the brush body is provided with a brush handle; characterized in that: the brush body is bendable and deformable, and the lower end of the brush body is provided with an adjusting rod, the adjusting rod being movable relative to the brush handle so that when the two ends of the brush body are close together, the brush body bends and deforms, and the outer contour increases, or when the two ends of the brush body are far apart, the brush body straightens and the outer contour decreases; a locking structure is provided between the adjusting rod and the brush handle, the locking structure comprising a locking head and a locking position, the locking head and the locking position being respectively disposed on the adjusting rod and the brush handle, the movement of the adjusting rod relative to the brush handle being limited by the locking head entering the locking position to restrict or lock the bending and deforming state of the brush body, and the relative movement is possible by the locking head exiting the locking position.

[0005] In this invention, the brush body is made of an elastic material or formed by hinged multiple brush blocks or brush strips. This structure allows the brush body to bend and deform.

[0006] In this invention, the brush body is a ring-shaped brush body, which can be a single piece or formed by combining multiple brush strips. This structure further optimizes the product.

[0007] In this invention, the inner wall of the brush body is provided with a groove, which is used to accommodate the bending deformation of the brush body, and the contact between adjacent groove walls limits the curvature of the brush body deformation; the brush body is provided with a slot in the longitudinal direction, which facilitates the bending of the brush body. The above-mentioned groove structure causes the outer contour of the brush body to arch outward when it bends and deforms, and the curvature of the brush body deformation is limited, making the product less prone to damage.

[0008] In this invention, the cleaning part includes brush bristles or a sponge. The above structure further optimizes the product.

[0009] In this invention, a guide rail is provided between the adjusting rod and the brush handle, allowing the adjusting rod to move up and down relative to the brush handle. This guide rail structure makes the movement of the adjusting rod relative to the brush handle simple and quick.

[0010] In this invention, the guide rail includes a brush handle sleeved on an adjusting rod, with a portion of the adjusting rod exposed outside the brush handle for operation. The guide rail enables the adjusting rod to move relative to the brush handle in a guiding manner.

[0011] In this invention, a rotatable locking head is connected to the brush handle. One end of the locking head has a locking head, and the other end has a spring between it and the brush handle. The spring acts on the locking head to allow the locking head to abut against the adjusting rod—maintaining a locking state. The adjusting rod has a locking position, which includes a sliding surface and a locking surface. When the adjusting rod moves upward relative to the brush handle, bringing the two ends of the brush body closer together, the adjusting rod slides with the locking head using the sliding surface and is limited by the locking head using the locking surface—preventing the adjusting rod from moving downward relative to the brush handle. When the two ends of the brush body move away, the spring end of the locking head is pressed down, causing the locking head to lift up—disengaging from the limiting position with the locking surface, thereby allowing the adjusting rod to move downward relative to the brush handle. The above-mentioned locking structure can achieve the purpose of limiting and releasing the limiting position of the adjusting rod after it moves relative to the brush handle.

[0012] In this invention, the locking head is located on the adjusting rod, and the locking position is located on the brush handle. The locking head of the adjusting rod protrudes from the brush handle for operation. When the adjusting rod moves upward relative to the brush handle, bringing the two ends of the brush body closer together, the adjusting rod engages the locking position with the locking head to limit its movement—preventing the adjusting rod from moving up and down relative to the brush handle. The locking head then disengages from the locking position, allowing the adjusting rod to move up and down relative to the brush handle. This locking structure also achieves the purpose of limiting and releasing the adjustment rod after it has moved relative to the brush handle.

[0013] In this invention, the locking head is located on the brush handle, and the locking head is elastic and operablely deformable. The locking position is located on the adjusting rod, and the locking position includes a sliding surface and a locking surface. When the adjusting rod moves upward relative to the brush handle, causing the two ends of the brush body to approach each other, the adjusting rod slides with the locking head using the sliding surface and is limited by the locking head using the locking surface—preventing the adjusting rod from moving downward relative to the brush handle. When the two ends of the brush body move away, the elastic locking head is operated to deform and disengage from the limiting position with the locking surface, thereby allowing the adjusting rod to move downward relative to the brush handle. The locking head extends from the brush handle or is rotatably mounted on the brush handle. A torsion spring is provided between the locking head and the brush handle, which gives the locking head elasticity and causes the locking head to abut against the adjusting rod—maintaining the locking state. The locking head is provided with an operating part. The above-mentioned locking structure can also achieve the purpose of limiting and releasing the adjustment rod after it moves relative to the brush handle.

[0014] In this invention, a spring B is provided between the adjusting rod and the brush handle. Spring B can cause the adjusting rod, in its non-limited state, to move downwards relative to the brush handle, thus moving the two ends of the brush body away from each other. This structure further optimizes the product.

[0015] The advantages of this invention are as follows: The brush of this invention includes a brush body and a cleaning section disposed on the surface of the brush body. The brush body is bendable and deformable, with a handle at the upper end and an adjusting rod at the lower end. The adjusting rod can move relative to the handle, causing the brush body to bend and deform, increasing its outer diameter, when the two ends are close together, or to straighten and shrink its outer diameter when the two ends are far apart. This brush, through adjustment, can be used to clean objects of different sizes, providing excellent cleaning results while saving time and effort. The bendable and deformable brush creates multi-directional cleaning sections, making cleaning the cavity simple and convenient. The locking structure allows the bendable and deformable brush body to be positioned for cleaning. Attached Figure Description

[0023] Detailed Description of Embodiments: The present invention will be further described below with reference to the accompanying drawings and through embodiments. (Refer to...) Figures 1 to 9 As shown: This invention discloses an adjustable and deformable brush, comprising a brush body and a cleaning section disposed on the surface of the brush body 1. The brush body has a handle 2 at its upper end. The brush body is characterized by its bendability and deformability, with an adjusting rod 3 at its lower end. The adjusting rod can move relative to the handle, causing the brush body to bend and deform, increasing its outer contour 4, when the two ends of the brush body are close together, or to straighten and decrease its outer contour 5, when the two ends of the brush body are far apart. The cleaning section includes bristles 17 or a sponge. After bending and deforming, the surface of the brush body forms a multi-directional cleaning section.

[0024] In this embodiment, the brush body is made of an elastic material or formed by hinged multiple brush blocks or brush strips. The elastic material includes a brush body made of elastic plastic, a brush body made of elastic metal wire, or a brush body made of elastic metal sheet; the elastic plastic includes PP, PE, PVC, TPR, TPU, etc., with a sponge attached to the surface of the plastic brush body or bristles implanted on the surface of the plastic brush body; the elastic metal wire has a sponge attached to its surface or at least two metal wires wrapped around bristles to form a brush; the elastic metal sheet has a sponge attached to its surface or bristles implanted on the surface of the plastic brush body.

[0025] In this embodiment, the brush body is a ring-shaped brush body, which can be a single piece or formed by combining multiple brush strips. Preferably, four brush strips are arranged in a ring, with the lower end of each strip connected to an adjusting rod and the upper end connected to a brush handle. Both ends of the brush body can be connected to the adjusting rod and the brush handle respectively via a snap-fit ​​structure. The bottom of the adjusting rod may have a cleaning section, and the adjusting rod includes a detachable bottom component, which facilitates product manufacturing.

[0026] In one embodiment, the inner wall of the brush body is provided with a groove 16, which is used to allow the brush body to bend and deform, and the contact between adjacent groove walls limits the curvature of the brush body deformation; the brush body is provided with a slot 6 in the longitudinal direction, which facilitates the bending of the brush body.

[0027] In this embodiment, a guide rail is provided between the adjusting rod and the brush handle, allowing the adjusting rod to move vertically relative to the brush handle. The guide rail includes a brush handle sleeved on the adjusting rod, with a portion of the adjusting rod protruding from the brush handle for operation. A handle can be connected to the operating end of the adjusting rod for ease of operation, and the handle is snap-fitted to the adjusting rod.

[0028] In this embodiment, a locking structure is provided between the adjusting rod and the brush handle. The locking structure includes a locking head 7 and a locking position 8, which are respectively located on the adjusting rod and the brush handle. The movement of the adjusting rod relative to the brush handle is limited by the locking head entering the locking position—limiting or locking the bending deformation state of the brush body; the relative movement is allowed when the locking head exits the locking position. There can be multiple sets of locking positions. When the adjusting rod moves relative to the brush handle to adjust the size of the brush body, the locking head can cooperate with locking positions at different positions to limit the movement. In the optimized example 1, a rotatable locking head 9 is connected to the brush handle, and a locking head 7 is provided at one end of the locking head 9. A spring 10 is provided between the other end and the brush handle. The spring acts on the locking head component so that the locking head of the locking head end 14 can abut against the adjusting rod—maintaining a locking state. The adjusting rod is provided with a locking position 8, which includes a sliding surface and a locking surface. When the adjusting rod moves upward relative to the brush handle and the two ends of the brush body are close together, the adjusting rod slides with the locking head using the sliding surface and is limited by the locking head using the locking surface—preventing the adjusting rod from moving downward relative to the brush handle. When the two ends of the brush body move away, the spring end 13 of the locking head component is pressed down to make the locking head lift up—exiting the limitation with the locking surface, so that the adjusting rod can move downward relative to the brush handle. The brush handle has a mounting groove 18 for a locking head. The two side walls of the mounting groove are respectively provided with shaft holes. The two side walls of the locking head are respectively provided with fulcrums that cooperate with the shaft holes. After the locking head is connected to the shaft holes through the fulcrums, it can rotate relative to the brush handle. The mounting groove has a slot hole for the locking head to pass through. The adjusting rod is partially located in the brush handle. The locking head can pass through the slot hole and abut against the adjusting rod. The brush handle can be a single piece or composed of multiple separate parts connected together. Figure 6 , Figure 7 In the optimized example 2, the locking head 7 is located on the adjusting rod 3, and the locking position 8 is located on the brush handle 2. The locking head of the adjusting rod is exposed on the brush handle for operation. When the adjusting rod moves upward relative to the brush handle so that the two ends of the brush body are close together, the adjusting rod engages the locking position with the locking head to limit the adjustment rod from moving up and down relative to the brush handle. The locking head can move up and down relative to the brush handle by disengaging from the locking position. The locking head is fixed to the adjusting rod or detachably connected to the adjusting rod through a snap-fit ​​structure or a spiral structure. The locking position includes a slot, and multiple slots can be set at intervals. Figure 8 , Figure 9 In the optimized example 3, the locking head 7 is located on the brush handle 2. The locking head is elastic and operablely deformable. The locking position 8 is located on the adjusting rod 3. The locking position includes a sliding surface and a locking surface. When the adjusting rod moves upward relative to the brush handle, bringing the two ends of the brush body closer together, the adjusting rod slides with the locking head using the sliding surface and is limited by the locking head using the locking surface—preventing the adjusting rod from moving downward relative to the brush handle. When the two ends of the brush body move away, the elastic locking head is operated to deform and disengage from the locking surface, allowing the adjusting rod to move downward relative to the brush handle. The locking head extends from the brush handle or is rotatably mounted on the brush handle. A torsion spring is provided between the locking head and the brush handle, giving the locking head elasticity and causing the locking head to abut against the adjusting rod—maintaining a locking state. The locking head is provided with an operating part 19. A spring B15 is provided between the adjusting rod and the brush handle in the above-mentioned locking structure. The spring B can cause the adjusting rod in the non-locking state to move downward relative to the brush handle, bringing the two ends of the brush body away.

[0029] The operation process of the brush in this embodiment is as follows: When cleaning objects with large cavities, the operator moves the adjusting rod upward relative to the brush handle, bringing the two ends of the brush body closer together, thereby bending and deforming the brush body to make its outline larger for cleaning; when cleaning objects with small cavities, the operator moves the adjusting rod downward relative to the brush handle, moving the two ends of the brush body away from each other, thereby straightening the brush body to make its outline smaller for cleaning; a locking structure is provided between the adjusting rod and the brush handle, which is used to limit or lock the bending and deforming state of the brush body when the brush body is bent and deformed, so that the brush can be used for cleaning operations. When the locking structure is released, spring B acts to move the adjusting rod downward relative to the brush handle, moving the two ends of the brush body away from each other for cleaning operations.

[0030] The brush of this invention includes a brush body and a cleaning section on the surface of the brush body. The brush body is bendable and deformable, with a handle at the upper end and an adjusting rod at the lower end. The adjusting rod can move relative to the handle, causing the brush body to bend and deform, increasing its outer diameter, when the two ends are close together, or to straighten and shrink its outer diameter when the two ends are far apart. This brush, through adjustment, can be used to clean objects of different sizes. It provides good cleaning results and saves time and effort. The bendable and deformable brush creates multi-directional cleaning sections, making cleaning the cavity simple and convenient. The locking structure allows the bendable and deformable brush body to be positioned for cleaning.

[0031] The above embodiments are merely examples of the present invention. Any substitutions or combinations between embodiments made in accordance with the spirit of the present invention should be understood as not departing from the protection scope of the present invention.
