Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, in particular to a brush rod assembly. Background Art

[0002] As people's living standards continue to improve, people pay more and more attention to home hygiene, especially the hygiene of toilets. People need to scrub the toilets frequently to ensure that they are clean and hygienic.

[0003] In the related art, there are cleaning brushes with a detachable brush rod assembly and brush head. The brush head is used as a disposable consumable. The end of the brush rod assembly is connected to a needle, which is inserted into the brush head through a vertical insertion method. The vertical insertion method makes the brush head poor in installation stability and easy to fall off.

[0004] In addition, the needles in the related art are directly connected to the end of the brush rod. When the brush head is not installed, the needles are exposed to the outside, which causes inconvenience in the storage of the brush rod. Utility Model Content

[0085] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0086] The following combination Figures 1 to 12 , describing the embodiments of the present utility model.

[0087] Example 1

[0088] This embodiment provides a brush rod assembly, including a brush rod and a brush head mounting structure.

[0089] Among them, the brush head mounting structure is used to install the brush head, and the brush head mounting structure is transmission-connected to the brush rod. A needle-shaped component is provided at the bottom of the brush head mounting structure. When the needle-shaped component contacts the brush head and the brush rod is driven to drive the brush head mounting structure toward the brush head, the needle-shaped component moves obliquely relative to the top of the brush head so as to obliquely penetrate the brush head and fix the brush head on the brush head mounting structure.

[0090] In this embodiment, when the brush rod is driven to move the brush head mounting structure toward the brush head, the needle assembly moves tilted relative to the top of the brush head to obliquely penetrate the brush head. Since the needle assembly obliquely penetrates the brush head, the brush head is not easy to fall off the needle assembly, thereby improving the installation stability.

[0091] In some embodiments, the needle assembly is arranged at an angle relative to the bottom of the brush head mounting structure. For example, the needle assembly may be positioned external to the brush head mounting structure, directly contacting the brush head, and when the brush rod is driven to move the brush head mounting structure toward the brush head, the needle assembly is driven to obliquely penetrate the brush head. Alternatively, the needle assembly may be positioned within the brush head mounting structure, and when the brush rod is driven to move the brush head mounting structure toward the brush head, the needle assembly extends from the brush head mounting structure, contacts the brush head, and obliquely penetrates the brush head.

[0092] In other embodiments, the needle-shaped component is arranged vertically to the bottom of the brush head mounting structure. The needle-shaped component can be located in the brush head mounting structure. When the brush rod is driven to drive the brush head mounting structure toward the brush head, the needle-shaped component moves out from the brush head mounting structure and moves obliquely relative to the top of the brush head so that it is inclined to penetrate the brush head.

[0093] In addition, the needle-shaped components can be arranged continuously or discontinuously at the bottom of the brush head mounting structure, which is not limited here.

[0094] In one embodiment, the needle assembly includes at least two groups of needle members 1. When the needle assembly contacts the brush head and the brush rod is driven to drive the brush head mounting structure to move toward the brush head, the first group of needle members 1 and the second group of needle members 1 move at different angles relative to the top of the brush head.

[0095] In this embodiment, when the needle-shaped assembly contacts the brush head and the brush rod is driven to drive the brush head mounting structure to move toward the brush head, the first group of needle-shaped members 1 and the second group of needle-shaped members 1 are tilted and moved at different angles relative to the top of the brush head. Since the first needle-shaped assembly and the second needle-shaped assembly are tilted at different angles in the brush head, the brush head can be further prevented from falling off the needle-shaped assembly, thereby improving the installation stability.

[0096] It should be noted that the first group of needle-like components and the second group of needle-like components are tilted and moved at different angles relative to the top of the brush head. Specifically, it may mean that the tilt directions of the first group of needle-like components and the second group of needle-like components are the same, but the tilt angles are different. It may also mean that the tilt directions of the first group of needle-like components and the second group of needle-like components are different.

[0097] In one embodiment, the needle assembly includes at least two rows of needles 1, the first row of needles 1 is arranged along the bottom edge of the brush head mounting structure, and the second row of needles 1 is arranged between the first row of needles 1 and the bottom center of the brush head mounting structure.

[0098] In this embodiment, since the needle assembly includes at least two rows of needle-shaped members 1, the first row of needle-shaped members 1 is arranged along the bottom edge of the brush head mounting structure, and the second row of needle-shaped members 1 is arranged between the first row of needle-shaped members 1 and the bottom center of the brush head mounting structure. The number of needle-shaped members 1 is large, which can increase the contact area with the brush head and further improve the installation stability.

[0099] Specifically, in one embodiment, the needle-shaped elements 1 in the same row have the same inclination direction, the same or different inclination angles, or the needle-shaped elements 1 in the same row have different inclination directions.

[0100] Specifically in one embodiment, the inclination directions of different rows of needle-shaped members 1 are different, or the inclination directions of different rows of needle-shaped members 1 are the same, and the inclination angles are the same or different.

[0101] It should be noted that the bottom of the brush head mounting structure can be of any shape, and the first row of needle-shaped members 1 can be arranged along its edge in any shape. This embodiment takes a circular shape as an example.

[0102] Specifically, the first row of needle-shaped elements 1 and the second row of needle-shaped elements 1 are both arranged in a circle.

[0103] In one embodiment, when the needle assembly contacts the brush head and the brush rod is driven to move the brush head mounting structure toward the brush head, the first row of needles 1 and the second row of needles 1 move tiltedly in opposite directions relative to the top of the brush head.

[0104] In this embodiment, when the needle-shaped assembly contacts the brush head and the brush rod is driven to drive the brush head mounting structure to move toward the brush head, the first row of needle-shaped members 1 and the second row of needle-shaped members 1 are tilted and moved in opposite directions relative to the top of the brush head. Therefore, the first row of needle-shaped members 1 and the second row of needle-shaped members 1 have different tilt directions in the brush head, which can further prevent the brush head from falling off from the needle-shaped assembly and improve the installation stability.

[0105] Specifically in one embodiment, Figure 3 As shown, the needle-shaped elements 1 in the first row are tilted in the counterclockwise direction, and the needle-shaped elements 1 in the second row are tilted in the clockwise direction.

[0106] In one embodiment, the brush rod is driven to drive the brush head mounting structure to move toward the brush head, and the brush head mounting structure drives the needle assembly to move, so that the needle assembly moves obliquely relative to the top of the brush head and obliquely penetrates the brush head.

[0107] In this embodiment, the brush rod is driven to drive the brush head mounting structure to move toward the brush head, and the brush head mounting structure drives the needle assembly to move, so that the needle assembly moves obliquely relative to the top of the brush head and obliquely penetrates the brush head. Since the needle assembly obliquely penetrates the brush head, the brush head is not easy to fall off the needle assembly, thereby improving the installation stability.

[0108] Specifically in one embodiment, the needle assembly includes at least two groups of needle-shaped members 1. The brush rod is driven to drive the brush head mounting structure to move toward the brush head. The brush head mounting structure drives at least two groups of needle-shaped members 1 to move. The first group of needle-shaped members 1 and the second group of needle-shaped members 1 move at different angles relative to the top of the brush head.

[0109] Specifically in one embodiment, the needle assembly includes at least two rows of needle members 1, the first row of needle members 1 is arranged along the bottom edge of the brush head mounting structure, and the second row of needle members 1 is arranged between the first row of needle members 1 and the bottom center of the brush head mounting structure. The brush rod is driven to drive the brush head mounting structure toward the brush head, and the brush head mounting structure drives at least two rows of needle members 1 to move.

[0110] In one embodiment, the brush rod is provided with a mating portion. When the brush rod is driven to move the brush head mounting structure toward the brush head, the brush head mounting structure slides in the mating portion to cause the needle assembly to move obliquely relative to the top of the brush head and obliquely penetrate the brush head.

[0111] In some embodiments, the mating portion is provided on the inner wall of the brush rod to save manufacturing costs. In other embodiments, the mating portion is provided on a mounting assembly independent of the brush rod body to facilitate disassembly and maintenance.

[0112] In this embodiment, by providing a matching portion, the movement direction of the brush head mounting structure can be guided to ensure that the needle assembly moves obliquely relative to the top of the brush head and obliquely penetrates the brush head, thereby ensuring installation stability.

[0113] In one embodiment, a first slide groove (not shown) is provided on one of the mating portion and the brush head mounting structure, and a first pin shaft (not shown) mating with the first slide groove is provided on the other, and the first slide groove is inclined or vertically arranged toward the brush head.

[0114] In this embodiment, the movement of the brush head mounting structure can be guided by providing a first sliding groove on one of the matching portion and the brush head mounting structure, and providing a first pin shaft that matches the first sliding groove on the other.

[0115] Specifically in one embodiment, the first slide groove is arranged to be inclined toward the brush head, so that the needle assembly can move obliquely relative to the top of the brush head and obliquely penetrate the brush head, thereby ensuring installation stability.

[0116] Specifically in one embodiment, the first slide groove is vertically arranged toward the brush head. Since the needle assembly is arranged at an angle, the needle assembly can also be moved obliquely relative to the top of the brush head and obliquely penetrate the brush head, thereby ensuring installation stability.

[0117] In one embodiment, the brush head mounting structure includes a first transmission member 3 and a second transmission member 4, a first needle assembly is provided at the bottom of the first transmission member 3, and a second needle assembly is provided at the bottom of the second transmission member 4, the first transmission member 3 is transmission-connected to the brush rod, and the second transmission member 4 is transmission-connected to the brush rod and the first transmission member 3. When the brush rod is driven to drive the first transmission member 3 toward the brush head, the first transmission member 3 and the second transmission member 4 slide in the mating part so that the first needle assembly and the second needle assembly move obliquely relative to the top of the brush head and obliquely penetrate into the brush head.

[0118] Among them, the setting of multiple transmission parts can increase the number of needle-shaped components on the one hand, and on the other hand, different inclined insertion angles can be cross-set to enhance the stability of the connection between the needle-shaped component and the brush head.

[0119] In this embodiment, a first needle assembly is provided at the bottom of the first transmission member 3 and a second needle assembly is provided at the bottom of the second transmission member 4. The moving direction of the first needle assembly can be controlled by controlling the moving direction of the first transmission member 3, and the moving direction of the second needle assembly can be controlled by controlling the moving direction of the second transmission member 4, thereby ensuring that the first needle assembly and the second needle assembly both move obliquely relative to the top of the brush head and obliquely penetrate the brush head.

[0120] It should be noted that the angle between the first needle assembly and the bottom of the first transmission member 3 and the angle between the second transfer assembly and the bottom of the second transmission member 4 are the same, and the inclination directions of the first needle assembly and the second needle assembly are the same; or, the angle between the first needle assembly and the bottom of the first transmission member 3 and the angle between the second transfer assembly and the bottom of the second transmission member 4 are the same, and the inclination directions of the first needle assembly and the second needle assembly are different; or, the angle between the first needle assembly and the bottom of the first transmission member 3 and the angle between the second transfer assembly and the bottom of the second transmission member 4 are different, and the inclination directions of the first needle assembly and the second needle assembly are different, or, the angle between the first needle assembly and the bottom of the first transmission member 3 and the angle between the second transfer assembly and the bottom of the second transmission member 4 are different, and the inclination directions of the first needle assembly and the second needle assembly are the same.

[0127] In one embodiment, the second sliding groove 2011 and the third sliding groove 401 are inclined in opposite directions toward the brush head.

[0128] In this embodiment, since the second chute 2011 and the third chute 401 are arranged in opposite directions toward the brush head, the first needle assembly and the second needle assembly can be inserted into the brush head in opposite directions. When the first needle assembly and the second needle assembly are inclined in different directions, on the one hand, the first needle assembly and the second needle assembly can both penetrate the brush head. On the other hand, the needle assembly and the brush head are arranged to penetrate in a cross-shaped manner, which increases the stability of the connection between the needle assembly and the brush head.

[0133] In one embodiment, the first angle and the second angle have opposite inclination directions.

[0134] In this embodiment, since the inclination directions of the first angle and the second angle are opposite, the inclination directions of the first needle-shaped assembly and the second needle-shaped assembly are correspondingly different.

The mating part is provided on the connecting assembly, and the connecting assembly guides the movement of the brush head mounting structure. The brush head mounting structure can move toward the brush head relative to the connecting assembly.

[0153] In one embodiment, a receiving cavity 8 is formed between the connecting assembly and the base 7 , and the brush head mounting structure is received in the receiving cavity 8 .

[0154] In this embodiment, since a receiving cavity 8 is formed between the connecting assembly and the base 7, the brush head mounting structure is accommodated in the receiving cavity 8. The receiving cavity 8 can accommodate the brush head mounting structure to avoid being exposed to the outside for a long time and being contaminated.

[0155] In one embodiment, when the brush rod is driven to move the brush head mounting structure toward the brush head, the needle assembly extends from the accommodating cavity 8.

[0165] In one embodiment, the brush head mounting structure includes a first reset member 9. When the brush rod is driven to move the brush head mounting structure toward the brush head, the first reset member 9 stores force. After the force applied to the brush rod is withdrawn, the first reset member 9 releases force to drive the brush head mounting structure to move away from the brush head.

[0166] In this embodiment, by providing a first reset member 9, when the brush rod is driven to drive the brush head mounting structure toward the brush head, the first reset member 9 stores force. After the force applied to the brush rod is withdrawn, the first reset member 9 releases the force to drive the brush head mounting structure to move away from the brush head, thereby achieving automatic reset and reducing manual operation.

[0167] In one embodiment, the brush rod includes a rod body, and the first restoring member 9 is arranged between the rod body and the brush head mounting structure, so that after the force applied to the brush rod is released, the first restoring member 9 drives the brush head mounting structure to move away from the brush head.

[0168] In this embodiment, the first reset member 9 is arranged between the rod body and the brush head mounting structure. For example, the first reset member 9 is set to a spring. When the brush rod is driven to drive the brush head mounting structure to move toward the brush head, the first reset member 9 is compressed.

After the force applied to the brush rod is withdrawn, the first reset member 9 drives the brush head mounting structure to move away from the brush head.

[0171] In one embodiment, the first restoring member 9 is configured as a spring.

[0172] In this embodiment, when the brush rod is driven to move the brush head mounting structure toward the brush head, the spring is compressed.

[0174] In this embodiment, by providing a limiting member 702 on the base 7, the spring can be limited to prevent the position of the spring from moving.

[0175] Specific as Figure 5 As shown, the limiting member 702 includes a plurality of sheet-like members spaced apart along the circumferential direction, each sheet-like member extends radially, and one end of each sheet-like member close to the circle is used to limit the spring.

[0176] Example 2

[0177] This embodiment provides a brush rod assembly, including a brush rod, a drive key 601 and a brush head mounting structure.

[0178] Among them, the driving key 601 is movably set on the brush rod; the brush head mounting structure is used to install the brush head, and the brush head mounting structure is transmission-connected to the driving key 601. A needle-shaped component is set at the bottom of the brush head mounting structure. When the brush rod is driven to drive the brush head mounting structure toward the brush head, the brush head mounting structure slides inside the brush rod to allow the needle-shaped component to extend so as to penetrate the brush head.

[0179] In this embodiment, a brush head mounting structure with a needle-shaped component at the bottom is provided. When the brush rod is driven to move the brush head mounting structure toward the brush head, the brush head mounting structure slides inside the brush rod so that the needle-shaped component extends and penetrates into the brush head. When the brush head is not installed, the brush head mounting structure with the needle-shaped component is accommodated in the brush rod, which is convenient for the user to store the brush rod component.

[0180] In one embodiment, the needle assembly can be inserted into the brush head at a right angle or at an angle. For example, the needle assembly is arranged perpendicular to the bottom of the brush head mounting structure. The needle assembly is located in the brush head mounting structure. When the brush head mounting structure slides vertically within the brush rod, the needle assembly extends and inserts into the brush head at a right angle for installation.

[0181] In addition, the needle-shaped components can be arranged continuously or discontinuously at the bottom of the brush head mounting structure, which is not limited here.

[0182] In one embodiment, the needle assembly includes at least two groups of needle members 1. When the needle assembly contacts the brush head and the brush rod is driven to drive the brush head mounting structure to move toward the brush head, the first group of needle members 1 and the second group of needle members 1 move at different angles relative to the top of the brush head.

[0183] In this embodiment, when the needle-shaped assembly contacts the brush head and the brush rod is driven to drive the brush head mounting structure to move toward the brush head, the first group of needle-shaped members 1 and the second group of needle-shaped members 1 are tilted and moved at different angles relative to the top of the brush head. Since the first needle-shaped assembly and the second needle-shaped assembly are tilted at different angles in the brush head, the brush head can be further prevented from falling off the needle-shaped assembly, thereby improving the installation stability.

[0184] It should be noted that the first group of needle-like components and the second group of needle-like components are tilted and moved at different angles relative to the top of the brush head. Specifically, it may mean that the tilt directions of the first group of needle-like components and the second group of needle-like components are the same, but the tilt angles are different. It may also mean that the tilt directions of the first group of needle-like components and the second group of needle-like components are different.

[0185] In one embodiment, the needle assembly includes at least two rows of needles 1, the first row of needles 1 is arranged along the bottom edge of the brush head mounting structure, and the second row of needles 1 is arranged between the first row of needles 1 and the bottom center of the brush head mounting structure.

[0186] In this embodiment, since the needle assembly includes at least two rows of needle-shaped members 1, the first row of needle-shaped members 1 is arranged along the bottom edge of the brush head mounting structure, and the second row of needle-shaped members 1 is arranged between the first row of needle-shaped members 1 and the bottom center of the brush head mounting structure. The number of needle-shaped members 1 is large, which can increase the contact area with the brush head and further improve the installation stability.

[0187] Specifically, in one embodiment, the needle-shaped elements 1 in the same row have the same inclination direction, the same or different inclination angles, or the needle-shaped elements 1 in the same row have different inclination directions.

[0188] Specifically in one embodiment, the inclination directions of different rows of needle-shaped members 1 are different, or the inclination directions of different rows of needle-shaped members 1 are the same, and the inclination angles are the same or different.

[0189] It should be noted that the bottom of the brush head mounting structure can be of any shape, and the first row of needle-shaped members 1 can be arranged along its edge in any shape. This embodiment takes a circular shape as an example.

[0190] Specifically, the first row of needle-shaped elements 1 and the second row of needle-shaped elements 1 are both arranged in a circle.

[0191] In one embodiment, when the needle assembly contacts the brush head and the brush rod is driven to move the brush head mounting structure toward the brush head, the first row of needles 1 and the second row of needles 1 move tiltedly in opposite directions relative to the top of the brush head.

[0192] In this embodiment, when the needle-shaped assembly contacts the brush head and the brush rod is driven to drive the brush head mounting structure to move toward the brush head, the first row of needle-shaped members 1 and the second row of needle-shaped members 1 are tilted and moved in opposite directions relative to the top of the brush head. Therefore, the first row of needle-shaped members 1 and the second row of needle-shaped members 1 have different tilt directions in the brush head, which can further prevent the brush head from falling off from the needle-shaped assembly and improve the installation stability.

[0193] Specifically in one embodiment, Figure 3 As shown, the needle-shaped elements 1 in the first row are tilted in the counterclockwise direction, and the needle-shaped elements 1 in the second row are tilted in the clockwise direction.

[0194] In one embodiment, the brush rod is driven to drive the brush head mounting structure to move toward the brush head, and the brush head mounting structure drives the needle assembly to move, so that the needle assembly moves obliquely relative to the top of the brush head and obliquely penetrates the brush head.

[0195] In this embodiment, the brush rod is driven to drive the brush head mounting structure to move toward the brush head, and the brush head mounting structure drives the needle assembly to move, so that the needle assembly moves obliquely relative to the top of the brush head and obliquely penetrates the brush head. Since the needle assembly obliquely penetrates the brush head, the brush head is not easy to fall off the needle assembly, thereby improving the installation stability.

[0196] Specifically in one embodiment, the needle assembly includes at least two groups of needle-shaped members 1. The brush rod is driven to drive the brush head mounting structure to move toward the brush head. The brush head mounting structure drives at least two groups of needle-shaped members 1 to move. The first group of needle-shaped members 1 and the second group of needle-shaped members 1 move at different angles relative to the top of the brush head.

[0197] Specifically in one embodiment, the needle assembly includes at least two rows of needle members 1, the first row of needle members 1 is arranged along the bottom edge of the brush head mounting structure, and the second row of needle members 1 is arranged between the first row of needle members 1 and the bottom center of the brush head mounting structure. The brush rod is driven to drive the brush head mounting structure toward the brush head, and the brush head mounting structure drives at least two rows of needle members 1 to move.

[0198] In one embodiment, the brush rod is provided with a matching portion, and when the brush rod is driven to drive the brush head mounting structure to move toward the brush head, the brush head mounting structure slides in the matching portion.

[0199] In this embodiment, the moving direction of the brush head mounting structure can be guided by providing the matching portion.

[0200] In some embodiments, the mating portion is provided on the inner wall of the brush rod to save manufacturing costs. In other embodiments, the mating portion is provided on a mounting assembly independent of the brush rod body to facilitate disassembly and maintenance.

[0201] In one embodiment, a first slide groove (not shown) is provided on one of the mating portion and the brush head mounting structure, and a first pin shaft (not shown) mating with the first slide groove is provided on the other, and the first slide groove is inclined or vertically arranged toward the brush head.

[0202] In this embodiment, the movement of the brush head mounting structure can be guided by providing a first sliding groove on one of the matching portion and the brush head mounting structure, and providing a first pin shaft that matches the first sliding groove on the other.

[0203] In one embodiment, the brush head mounting structure includes a first transmission member 3 and a second transmission member 4, a first needle assembly is provided at the bottom of the first transmission member 3, and a second needle assembly is provided at the bottom of the second transmission member 4, the first transmission member 3 is transmission-connected to the brush rod, and the second transmission member 4 is transmission-connected to the brush rod and the first transmission member 3. When the brush rod is driven to drive the first transmission member 3 toward the brush head, the first transmission member 3 and the second transmission member 4 slide in the mating part so that the first needle assembly and the second needle assembly move obliquely relative to the top of the brush head and obliquely penetrate into the brush head.

[0204] Among them, the setting of multiple transmission parts can increase the number of needle-shaped components on the one hand, and on the other hand, different inclined insertion angles can be cross-set to enhance the stability of the connection between the needle-shaped component and the brush head.

[0205] In this embodiment, a first needle assembly is provided at the bottom of the first transmission member 3 and a second needle assembly is provided at the bottom of the second transmission member 4. The moving direction of the first needle assembly can be controlled by controlling the moving direction of the first transmission member 3, and the moving direction of the second needle assembly can be controlled by controlling the moving direction of the second transmission member 4, thereby ensuring that the first needle assembly and the second needle assembly both move obliquely relative to the top of the brush head and obliquely penetrate the brush head.

[0206] It should be noted that the angle between the first needle assembly and the bottom of the first transmission member 3 and the angle between the second transfer assembly and the bottom of the second transmission member 4 are the same, and the inclination directions of the first needle assembly and the second needle assembly are the same; or, the angle between the first needle assembly and the bottom of the first transmission member 3 and the angle between the second transfer assembly and the bottom of the second transmission member 4 are the same, and the inclination directions of the first needle assembly and the second needle assembly are different; or, the angle between the first needle assembly and the bottom of the first transmission member 3 and the angle between the second transfer assembly and the bottom of the second transmission member 4 are different, and the inclination directions of the first needle assembly and the second needle assembly are different, or, the angle between the first needle assembly and the bottom of the first transmission member 3 and the angle between the second transfer assembly and the bottom of the second transmission member 4 are different, and the inclination directions of the first needle assembly and the second needle assembly are the same.

[0212] It should be noted that the second chute 2011 is tilted or vertically arranged toward the brush head, and the third chute 401 is tilted or vertically arranged toward the brush head, both of which can enable the needle-shaped component to obliquely penetrate the brush head.

[0213] In one embodiment, the second sliding groove 2011 and the third sliding groove 401 are inclined in opposite directions toward the brush head.

[0214] In this embodiment, since the second chute 2011 and the third chute 401 are arranged in opposite directions toward the brush head, the first needle assembly and the second needle assembly can be inserted into the brush head in opposite directions. When the first needle assembly and the second needle assembly are inclined in different directions, on the one hand, the first needle assembly and the second needle assembly can both penetrate the brush head.
