Description

Technical Field

[0001] The utility model belongs to the field of vacuum cleaners and their components, and particularly relates to a roller brush mounting member, a floor brush of a vacuum cleaner, and a vacuum cleaner. Background Art

[0002] A vacuum cleaner uses a high-speed rotating electric fan to generate negative pressure, forming a high-speed air flow from the outside to the inside. Through the high-speed air flow, dirt such as dust and hair on the surface to be cleaned near the floor brush is transported into the dust collection bucket of the vacuum cleaner. In order to collect dirt more effectively, a rotatable roller brush is usually provided in the floor brush. The roller brush generally includes a roller body and brush strips provided on the surface of the roller body. The brush strips can be brush wire structures or rubber strip structures, etc. The roller brush contacts the surface to be cleaned through the opening of the floor brush. During the rotation of the roller brush, the brush strips beat and rub the surface to be cleaned, prompting the dirt to loosen and detach from the surface to be cleaned, and thus enter the vacuum cleaner along with the air flow.

[0003] In the floor brush, the roller brush has the longest contact time and the largest contact area with the dirt, is most easily soiled, and is most easily entangled with dirt such as hair during rotation. When serious entanglement occurs, the roller brush may even be unable to rotate. Therefore, in order to avoid these problems from affecting the dust collection performance, it is necessary to regularly remove the roller brush for cleaning.

[0004] In the prior art, for example, after opening the cover plate in Chinese patent document CN210697482U, the roller brush still stays in its original position, and it is necessary to manually break the roller brush away from its original position and then take it out, which is time-consuming and laborious. To solve this problem, most of the ejection structures in the prior art are fixed on the floor brush housing or integrally formed with the floor brush housing, or are fixedly enclosed in the housing and cannot be taken out (such as springs, elastic members). If damaged, the entire floor brush housing needs to be replaced, which is costly and not conducive to maintenance. Summary of the Utility Model

[0005] The present utility model is made to solve the above problems, and aims to provide a roller brush mounting member, a floor brush of a vacuum cleaner, and a vacuum cleaner, which can facilitate the user to disassemble and assemble the roller brush and is easy to maintain.

[0006] To achieve the above object, the present utility model adopts the following solutions:

[0007] <Floor Brush of Vacuum Cleaner>

[0008] The present utility model provides a vacuum cleaner floor brush for cleaning dirt on a surface to be cleaned, comprising: a housing; a receiving cavity formed within the housing for receiving a roller brush and having a cleaning opening for the roller brush to contact the surface to be cleaned; an end cap for mounting the roller brush into the receiving cavity; one side detachably and matingly connected to the end of the roller brush, and the other side mating with the side of the receiving cavity; a hollow mounting cavity formed inside; a locking mechanism for locking and unlocking the end cap; an ejecting mechanism provided in the end cap, comprising: an elastic member detachably mounted in the mounting cavity, and an ejecting rod having one end in contact with the elastic member and the other end extending out of the end cap and abutting against the side of the receiving cavity; wherein, in the locked state, the ejecting rod compresses the elastic member inwardly; in the unlocked state, the elastic member pushes the ejecting rod to jack outwards.

[0009] The beneficial effects of the above solution are as follows:

[0010] The ejecting mechanism is located in the end cap and can be separated from the receiving cavity and the roller brush along with the end cap. Thus, when the ejecting mechanism needs to be replaced, the end cap can be taken out, and only the end cap or the ejecting mechanism can be replaced, or only the elastic member / ejecting rod can be replaced, without replacing the entire housing, which is easy to maintain. Moreover, the ejecting mechanism adopts an elastic member and an ejecting rod, and through a simple structure, the end cap can jack itself out of the receiving cavity in the unlocked state, thereby lifting the roller brush, which is convenient for the user to take out the end cap and the roller brush.

[0011] Preferably, in the vacuum cleaner floor brush provided by the present utility model, the mounting cavity is located in the central region inside the end cap, and an inspection opening is provided on the inner side facing the roller brush. Such a design makes the inspection process of the ejecting mechanism more convenient, facilitating the observation of whether the ejecting mechanism is damaged and where it is damaged, so as to replace and repair it more pertinently.

[0012] Specifically, in the vacuum cleaner floor brush provided by the present utility model, the end cap includes a rotating shaft and a shaft cap detachably covering the rotating shaft; the rotating shaft is fitted into the end of the roller brush; the shaft cap mates with the side of the receiving cavity and has a mounting cavity formed inside.

[0013] Preferably, in the vacuum cleaner floor brush provided by the present utility model, the shaft cap and the side of the receiving cavity are mutually fitted, so that the installation is more stable.

[0014] Preferably, in the vacuum cleaner floor brush provided by the present utility model, an elastic member mounting seat and an ejecting rod extending hole are provided in the mounting cavity, so that the elastic member is more stably mounted and the ejecting rod moves more stably.

[0015] Preferably, in the floor brush of the vacuum cleaner provided by the present utility model, a limiting ring is provided on the inner section of the ejecting rod located inside the accommodating cavity. The diameter of the limiting ring is larger than the ejecting hole of the ejecting rod. A cross-shaped fitting head is provided at the top of the inner section, and the cross-shaped fitting head is fitted with the end of the elastic member in a matching manner. This can enable the ejecting rod to move more stably in the ejecting hole of the ejecting rod, prevent the ejecting rod from detaching from the accommodating cavity and the ejecting hole, make the cooperation between the elastic member and the ejecting rod more firm, and facilitate disassembly at the same time.

[0016] Preferably, in the floor brush of the vacuum cleaner provided by the present utility model, the elastic member is a spring and the ejecting rod is a plastic rod, with a simple structure and low cost.

[0017] Specifically, in the floor brush of the vacuum cleaner provided by the present utility model, the cross-sectional shape of the installation cavity can be circular, rectangular, annular, etc.

[0018] Preferably, in the floor brush of the vacuum cleaner provided by the present utility model, the locking mechanism has an operating unit and a rotating unit. The operating unit is arranged on the housing, behind the cleaning opening, and a part of the rotating unit is arranged on the side of the cleaning opening. Such a design makes the strength and stability of the side of the floor brush higher, the locking mechanism more firm, reduces its installation difficulty, and enables the side area of the floor brush to be as narrow as possible, which is beneficial for the floor brush to enter narrow areas for cleaning.

[0019] Preferably, in the floor brush of the vacuum cleaner provided by the present utility model, the rotating unit includes a shaft rod and a baffle. The shaft rod is installed at the front side corner of the cleaning opening far from the operating unit, and the rotating end of the baffle is fitted and rotates around the shaft rod. The locking end of the baffle extends to the rear of the cleaning opening and is located beside the operating unit, and the locking end is matched with the operating unit for locking and unlocking. A part of the shaft rod and the locking end of the baffle are located in front of and behind the cleaning opening, rather than beside it, which can further reduce the installation difficulty and make the side area of the floor brush narrower.

[0020] Specifically, in the floor brush of the vacuum cleaner provided by the present utility model, the operating unit includes an operating member that moves horizontally back and forth along the axial direction of the roller brush and an elastic member that compresses and pushes the operating member when the operating member moves back and forth; the operating member has a pulling button exposed on the housing and a beveled platform that extends from the unexposed part of the pulling button to match the locking end.

[0021] <Roller brush mounting member>

[0022] Further, the present utility model also provides a roller brush mounting member for cooperating with a locking mechanism to lock the roller brush in or unlock it from the receiving cavity of the floor brush, including: an end cap for mounting the roller brush into the receiving cavity; one side detachably and matingly connected to the end of the roller brush, and the other side mating with the side of the receiving cavity; a hollow mounting cavity formed inside; an ejecting mechanism provided in the end cap, including: an elastic member detachably mounted in the mounting cavity, and an ejecting rod having one end in contact with the elastic member and the other end extending out of the end cap and abutting against the side of the receiving cavity; wherein, in the locked state, the ejecting rod inwardly compresses the elastic member; in the unlocked state, the elastic member pushes the ejecting rod to jack outwards. This roller brush mounting member has an end cap and an ejecting mechanism with the same structure as the <vacuum cleaner floor brush> above, and correspondingly has the same beneficial effects as the <vacuum cleaner floor brush>.

[0023] <Vacuum cleaner>

[0024] Further, the present utility model also provides a vacuum cleaner, which includes the vacuum cleaner floor brush described in the <vacuum cleaner floor brush> above. Similarly, this vacuum cleaner has the same beneficial effects as the <vacuum cleaner floor brush>. Description of the Drawings

[0033] The following will describe in detail the specific implementation manners of the roller brush mounting member, the floor brush of the vacuum cleaner, and the vacuum cleaner involved in the present utility model with reference to the accompanying drawings.

[0034] <Embodiment>

[0035] As Figures 1-6 shown, the floor brush 1000 of the vacuum cleaner is used to cooperate with the vacuum cleaner main body to clean the surface to be cleaned. It includes a housing 10, a roller brush 20, a connecting pipe 30, a receiving cavity 40, an end cap 50, a locking mechanism 60, and an ejecting mechanism 70.

[0036] The housing 10 includes left and right side parts, upper and lower covers, and a frame inside. And a motor for driving the roller brush 20 to rotate at a high speed is provided inside the housing 10.

[0037] The roller brush 20 is installed in the housing 10 and can rotate at a high speed.

[0038] The connecting pipe 30 is used to connect the vacuum cleaner main body or an extension pipe, so that the receiving cavity 40 is communicated with the vacuum cleaner main body.

[0039] The receiving cavity 40 is formed inside the housing 10, can accommodate the roller brush 20, and has a cleaning opening 41 for the roller brush 20 to contact the surface to be cleaned.

[0040] As Figures 2-4 shown, the end cap 50 installs the roller brush 20 into the receiving cavity 40. It includes a rotating shaft 51, a shaft cap 52, an installation cavity 53, an elastic member mounting seat 54, and an ejecting rod through hole.

[0041] As Figure 4 and 6 shown, the rotating shaft 51 is a barrel-shaped structure extending along the axial direction of the roller brush 20 and having an opening at the bottom. The annular barrel part (inner end) of the rotating shaft 51 can be fitted into the end of the roller brush 20, and a circle of convex ribs engaged with the inner surface of the roller brush 20 are arranged on the outer surface. The rotating shaft 51 can rotate synchronously with the roller brush 20, and the rotating shaft 51 can be pulled out (disassembled and separated) from the end of the roller brush 20 by the user. The top (outer end) of the rotating shaft 51 protrudes outside the end of the roller brush 20 and is detachably connected to the shaft cap 52 through a bearing 511 located in the middle, and can rotate relative to the shaft cap 52 at a high speed. The outer surface of the bearing 511 is engaged with the inner surface of the shaft cap 52.

[0042] As Figures 3-6As shown, the shaft cover 52 covers the outer end of the rotating shaft 51, and includes a cover body 521 and a protrusion 522 formed on the outer side of the cover body 521. The inner side of the cover body 521 is an annular structure, including an outer ring 521a formed at the cover edge and an inner ring 521b located in the central area of the outer ring 521a. The outer ring 521a surrounds the periphery of the outer end of the rotating shaft 51 and is spaced from the periphery of the outer end of the rotating shaft 51 by a certain distance. A circle of convex ribs is arranged on the inner side of the inner ring 521b, which is mutually engaged with the outer surface of the bearing 511, and through this shaft cover 52, it can be pulled out (disassembled and separated) by the user from the end of the roller brush 20. A part of the shaft cover 52 corresponding to the inner ring 521b axially forms a protrusion 522 outward. The outer side of the protrusion 522 is mutually engaged with a side part of the accommodation cavity 40 and is hollow inside.

[0043] An installation cavity 53 is formed inside the protrusion 522. When the shaft cover 52 covers the rotating shaft 51, the installation cavity 53 is located in the central area inside the end cover 50 and is provided with an inspection opening facing the inner side of the roller brush. In this embodiment, the cross-section of the installation cavity 53 is circular.

[0044] The elastic member mounting seat 54 and the ejector rod through hole are both arranged in the installation cavity 53. As Figure 5 shown, the elastic member mounting seat 54 is a groove provided on a side wall of the installation cavity 53. The ejector rod through hole is arranged opposite to the elastic member mounting seat 54 and is a through hole opened on the other side wall of the installation cavity 53. Since the cross-section of the installation cavity 53 is circular, the mounting seat 54 and the ejector rod through hole are respectively located at both ends of the diameter of the circular cross-section.

[0045] As Figures 2-3 shown in FIGS. 6-8, the locking mechanism 60 is used to lock and unlock the end cover 50. The locking mechanism 60 includes an operating unit 61 and a rotating unit 62.

[0046] The operating unit 61 includes an operating member 611 and an elastic member 612, both of which are arranged in the housing 10, behind the cleaning opening 41, rather than beside the cleaning opening 41. The operating member 611 can move horizontally back and forth along the axis of the roller brush 20; the operating member 611 has a pulling button 611a and a clamping platform 611b. The pulling button 611a is the exposed part of the operating member 611 and exposes the housing 10; the clamping platform 611b extends from the unexposed part of the pulling button 611a to match the locking end and is a convex platform with an inclined surface. The elastic member 612 is a spring and can compress and push the operating member 611 when the operating member 611 moves back and forth.

[0047] A part of the rotating unit 62 is disposed at the side of the cleaning opening 41. The rotating unit 62 includes a shaft rod 621 and a baffle 622. The shaft rod 621 is installed at the front side corner of the cleaning opening away from the operation unit 61. The rotating end 622a of the baffle 622 is matched with and rotates around the shaft rod 621. The locking end 622b of the baffle 622 extends to the rear of the cleaning opening 41 and is located beside the operation unit 61. The locking end 622b is matched with the operation unit 61 for locking and unlocking. A rectangular bayonet is provided on the locking end 622b, and the bayonet is correspondingly matched and clamped with the clamping platform 611b. Between the rotating end 622a and the locking end 622b is a connecting plate 622c, and the connecting plate 622c corresponds to the bottom of the outer surface of the protrusion 522.

[0048] When locking, the locking end 622b abuts against the clamping platform 611b and then compresses the elastic member 612 inward until the bayonet of the locking end 622b faces the clamping platform 611b. At this time, the clamping platform 611b and the elastic member 612 are not abutted by the locking end 622b, and the elastic member 612 pushes the clamping platform 611b into the bayonet outward. When unlocking, the user compresses the elastic member 612 inward by pulling the button 611a, so that the clamping platform 611b leaves the bayonet.

[0049] As Figures 3-8 shown, the ejecting mechanism 70 is disposed in the end cover 50, and it includes an elastic member 71 and an ejecting rod 72. The elastic member 71 is detachably installed on the elastic member mounting seat 54 in the mounting cavity 53. The inner end of the ejecting rod 72 contacts the elastic member 71, and the outer end extends out of the end cover 50 through the ejecting rod through hole and abuts against the side of the accommodating cavity 40. In this embodiment, the side of the accommodating cavity 40 is matched with the outside of the end cover 50 to be a semi-circular arc shape, and the outer end of the ejecting rod 72 abuts against the semi-circular arc-shaped structure; the elastic member 71 is a spring, and the ejecting rod 72 is a plastic rod with a smooth outer end. Further, as Figure 4 and 5 shown, in this embodiment, a ring of limiting rings 721 (radial protrusions of the rod) is provided on the inner section of the ejecting rod 72 located inside the accommodating cavity 40. The diameter of the limiting ring 721 is larger than the inner diameter of the ejecting rod through hole. At the top of the inner section of the ejecting rod 72, a cross-shaped fitting head 722 is provided, and the cross-shaped fitting head 722 is fitted and engaged with the end of the elastic member 71.

[0050] Based on the above structure, the specific working process of the vacuum cleaner floor brush 1000 provided in this embodiment for disassembling and assembling the roller brush 20 is as follows:

[0051] When the user needs to take out the roller brush 20 from the accommodating cavity 40, as Figure 2 and 6As shown, the user pulls the pull button 611a to the right, driving the clamping platform 611b to move to the right, thereby compressing the elastic member 612 until the clamping platform 611b disengages from the clamping opening of the locking end 622b and enters the unlocked state. At the same time when the clamping platform 611b disengages from the clamping opening of the locking end 622b, as Figure 3 and 7 shown, the elastic member 71 in the accommodation cavity 40 pushes the ejector rod 72 to eject outwards, so that the end cover 50 together with the roller brush 20 is lifted out of the accommodation cavity 40, causing both the end cover 50 and the roller brush 20 to leave their original positions (installation positions). At the same time, the connecting plate 622c of the locking mechanism 60 is lifted by the end cover 50 and rotates away from the cleaning opening 41 around the shaft rod 621. The user can take out the end cover 50 and the roller brush 20 by lifting the end cover 50 upwards, thereby cleaning and maintaining the roller brush 20.

[0052] Moreover, when it is necessary to clean or maintain the end cover 50 and the roller brush 20 separately, the user can also pull the end cover 50 outwards along the axial direction of the roller brush 20, so that the end cover 50 and the roller brush 20 are successfully separated. Further, if it is necessary to repair or replace the ejecting mechanism 70, the shaft cover 52 and the rotating shaft 51 can be pulled away from each other along the axial direction of the end cover 50.

[0053] After the user finishes cleaning and maintaining, the rotating shaft 51 of the end cover 50 and the roller brush 20 are coaxially installed, and then the shaft cover 52 is aligned with the fitting area on the side of the accommodation cavity 40, and they are put into the accommodation cavity 40 together. At this time, the floor brush 1000 of the vacuum cleaner is still in the Figure 7 state, and the connecting plate 622c of the locking mechanism 60 is still lifted by the end cover 50. The user presses down the connecting plate 622c, and then presses down the end cover 50 to the installation position. At the same time, the locking end 622b abuts against the clamping platform 611b and automatically compresses the elastic member 612 inwards until the clamping platform 611b is pushed into the clamping opening and enters the locking state as shown in Figure 2 and 8 shown. At this time, the user can connect the floor brush 1000 of the vacuum cleaner to the main suction pipe or its extension pipe of the vacuum cleaner main body to perform operations such as vacuuming.

[0054] The above embodiments are merely illustrative examples of the technical solutions of the present utility model.
