Description

Technical Field

[0001] This utility model relates to the field of pool cleaning brush technology, and more specifically, to a quick-release structure for a brush head and handle connector. Background Technology

[0002] As living standards improve, swimming pools are becoming increasingly popular as recreational facilities for swimming and relaxation. To keep pools clean, cleaning tools are essential. Pools require regular cleaning, and the primary cleaning tools currently used are cleaning brushes, which can be further categorized into wall brushes and floor brushes depending on the area being cleaned.

[0003] In existing technologies, both wall brushes and floor brushes are mostly elongated in shape, with a handle at the top and bristles at the bottom, suitable for general pool cleaning. However, they pose challenges for cleaning small areas near scaffolding and corners facing straight walls. To address this issue, smaller, more mobile brush heads and designs that add side brushes to both ends of an elongated brush have emerged. Currently, these different types of brush heads are generally fixed to the handle connector, requiring users to purchase multiple brush heads and handle connectors simultaneously. Since the handle connectors are interchangeable, this increases the cost of the handle connectors and leads to unnecessary waste. Summary of the Invention

[0004] To overcome at least one of the defects in the prior art, this utility model provides a quick-release structure for a brush head and a handle connector, in which the brush head and handle are detachable. The handle and handle connector are universal components, and users only need to replace different types of brush heads, eliminating redundant and repetitive handle connectors and saving costs.

[0005] This utility model provides a quick-connect structure for a brush head and a handle connector: it includes a handle connector for connecting the handle and a connecting tube formed on the brush head body. The handle connector is provided with a receiving cavity, and at least two positioning holes are provided on the side wall of the receiving cavity. At least two connecting plates that can be elastically deformed under radial force are provided at the upper end of the connecting tube, and each connecting plate is provided with a positioning protrusion at its upper end. When the upper end of the connecting tube is inserted into the receiving cavity, each positioning protrusion is fitted into the positioning hole from the inside out.

[0006] Compared with the prior art, the quick-connect structure of the brush head and handle connector of this utility model has the following advantages:

[0007] This invention separates the traditional integral brush head assembly into a detachable brush head body and a handle connector. A connecting tube is formed on the brush head body, and a receiving cavity is provided on the handle connector. The upper end of the connecting tube can be inserted into the receiving cavity. After the two parts are axially installed, they are limited by the matching of the positioning protrusion and the positioning hole to prevent axial separation. In this structure, the handle connector is a universal component that can be matched with different types of brush head bodies. When disassembly is required, pressing the positioning protrusion from the outside to the inside will cause the connecting plate to deform elastically in the radial direction until the positioning protrusion disengages from the positioning hole, thus separating the brush head body and the handle connector axially. This is very convenient, requires no fasteners, has a simple structure, and is low in cost.

[0008] As a preferred structure, the connecting plates are two symmetrically arranged along the central axis of the connecting tube, and two positioning slots are symmetrically arranged on the inner side of the connecting tube. The lower ends of the two connecting plates are detachably inserted and positioned in the two positioning slots. In the above modified structure, the symmetrical arrangement of the two connecting plates and the positioning protrusion structure makes it more convenient for the user to replace the brush head body. The user can simply press the two positioning protrusions against each other with two fingers of one hand, which is very convenient.

[0009] Furthermore, there are two corresponding positioning holes, and positioning baffles are formed on both sides of the two positioning holes in the vertical direction on the inner wall of the accommodating cavity. The upper end of the connecting plate and the two side walls in its width direction are respectively positioned between the two positioning baffles.

[0010] In a further improvement, the outer wall of the connecting pipe is provided with right-angled stepped stop grooves at positions corresponding to the two positioning slots. The lower ends of the two positioning slots extend through the horizontal end faces of the stop grooves, and the lower ends of the two connecting plates protrude through the horizontal end faces. Each connecting plate also has a positioning hook formed at its lower end that abuts against the horizontal end face. In this improved structure, the stop grooves allow for better axial positioning of the lower ends of the connecting plates after insertion, improving the stability of the insertion structure.

[0011] In a further improvement, both side walls of the two connecting plates in the width direction are formed with protruding positioning bosses, and the lower end face of each positioning boss abuts against the upper end face of the corresponding positioning slot. In the above improved structure, the positioning boss structure can still limit the downward movement of the connecting plates after insertion, ensuring the height position of the positioning protrusions. This allows the two positioning protrusions to be quickly and accurately fitted into the two positioning holes after the brush head body and handle connector are inserted.

[0012] As another preferred structure, the connecting plates are two symmetrically arranged along the central axis of the connecting pipe, and the two connecting plates are directly integrally formed on the connecting pipe.

[0013] In a further improvement, a suction pipe connector is detachably connected to the handle connector. This suction pipe connector communicates with the receiving cavity, and the brush head body has a suction through-hole that communicates with the inner cavity of the connecting pipe. In this improved structure, during the brush's cleaning process, debris can be directly extracted by the suction pump through the suction through-hole, improving the cleaning effect.

[0014] Other improvements and advantages of this invention will be set forth in the detailed description that follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures particularly pointed out in the description and drawings. Attached Figure Description

[0025] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0026] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "fixed" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0027] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Example 1

[0028] See Figures 1 to 8 As shown in the figure, this application discloses a quick-connect structure for a brush head and a handle connector, including a handle connector 1 and a connecting tube 3 formed on the brush head body 2. The connecting tube 3 is arranged vertically to facilitate connection with the handle structure. The handle connector 1 is used for detachable connection of a long handle so that users can clean while standing, which is more labor-saving.

[0029] More specifically, the handle connector 1 includes a connector body and a connecting rod, wherein the connecting rod is set at a certain angle on the side wall of the connector body. The lower end of the connector body is provided with a receiving cavity 4, and at least two positioning holes 5 are opened on the side wall of the receiving cavity 4; correspondingly, at least two connecting plates 6 are provided on the upper end of the connecting tube 3, and the connecting plate 6 is a connecting plate 6 that can elastically deform under radial force, and each connecting plate 6 is provided with a positioning protrusion 7 at its upper end. When the upper end of the connecting tube 3 is inserted into the receiving cavity 4, each positioning protrusion 7 is fitted into the positioning hole 5 from the inside out, realizing the connection and fixation of the brush head and the handle connector 1. When disassembly is required, the positioning protrusion 7 can be pressed from the outside in by hand to drive the connecting plate 6 to elastically deform in the radial direction until the positioning protrusion 7 is disengaged from the positioning hole 5, and the brush head body and the handle connector 1 can be separated axially. It is very convenient and does not require any fasteners. The structure is simple and the cost is low.

[0030] In this embodiment, the upper outer wall of the connector body is an arc-shaped structure, which looks more aesthetically pleasing and elegant. Furthermore, the positioning insertion hole 5 in the above structure is also located on the arc-shaped surface. Preferably, there are two connecting plates 6 symmetrically arranged along the central axis of the connecting tube 3, and two positioning slots 8 symmetrically arranged on the inner side of the connecting tube 3. The lower ends of the two connecting plates 6 are detachably inserted and positioned in the two positioning slots 8. This structure, with two connecting plates 6 and positioning protrusions 7, makes it more convenient for the user to replace the brush head body 2. The user can simply press the two positioning protrusions 7 against each other with two fingers of one hand, which is very convenient. If there are too many positioning protrusions 7, it becomes difficult to easily replace the brush head with one hand.

[0031] Furthermore, in the aforementioned structure, there are also two corresponding positioning holes 5, and positioning baffles are formed on both sides of the two positioning holes 5 in the vertical direction on the inner wall of the accommodating cavity 4. The upper ends of the two connecting plates 6 and their side walls in the width direction are respectively positioned between the two positioning baffles at the corresponding positions, effectively ensuring the stability of the insertion structure. At the same time, the channel between the two positioning baffles can also play a guiding role during the assembly process, ensuring that the positioning protrusions 7 are assembled into the corresponding positioning holes 5 more quickly and accurately.

[0032] In this embodiment, in order to further ensure the stability of the insertion structure between the connecting plate 6 and the connecting tube 3, right-angled stepped stop grooves are provided on the outer wall of the connecting tube 3 at positions corresponding to the two positioning slots 8. The lower ends of the two positioning slots 8 extend through to the horizontal end face of the stop groove. Therefore, when the lower ends of the two connecting plates 6 are inserted into the positioning slots 8, the lower ends of the two connecting plates 6 protrude through the horizontal end face. The lower ends of the two connecting plates 6 are formed with positioning hooks 11 that abut against the horizontal end face to achieve vertical positioning.

[0033] More specifically, the above structure only achieves a limit on movement from bottom to top. Although it can maintain stability after the handle connector 1 is installed and does not affect use, there is a risk of downward movement during the installation of the upper end of the connecting plate 6 and the handle connector 1, which would prevent the positioning protrusion 7 from accurately engaging with the positioning socket 5. Therefore, in this embodiment, positioning protrusions 12 are formed on both side walls of the two connecting plates 6 in the width direction, and the lower end face of each positioning protrusion 12 abuts against the upper end face of the corresponding positioning slot 8, further limiting the downward movement of the connecting plate 6 and ensuring that the two positioning protrusions 7 can accurately engage with the two positioning sockets 5 during the assembly of the brush head body 2 and the handle connector 1. Example 2

[0034] See appendix Figure 7 and 8The structure of this embodiment is largely the same as that of Embodiment 1. The only difference is that when the brush head body 2 is a small cylindrical brush head, the two connecting plates 6 are directly integrally formed and fixed to the comb body, without the need for separate forming and subsequent insertion, thus saving costs. Example 3

[0035] Participate in the attached Figure 1 Alternatively, based on Embodiment 1 or Embodiment 2, the handle structure of this embodiment can be further supplemented with a suction pipe connector 13. The suction pipe connector is connected to the accommodating cavity 4, and the brush head body 2 is provided with a suction through hole that connects to the inner cavity of the connecting pipe 3. The suction pipe connector 13 is connected to an external suction pump through a flexible hose. During the brush cleaning of the floor, the garbage can be directly extracted by the suction pump through the suction through hole, thereby improving the cleaning effect.
