Description

Technical Field

[0001] The utility model relates to the technical field of household cleaning, and particularly relates to a lifting and locking structure for a brush barrel. Background Art

[0002] Application No. 2024202816136 provides a brush barrel structure for a cleaning tool. It includes: a barrel base, on which there is a placement area and holes for inserting a brush rod; an inner barrel that can move up and down; a lever member hinged to the barrel base and pushing the inner barrel to move, and one end of the brush rod inserted into the hole can contact one end of the lever member; a barrel cover connected to the lever, and the barrel cover includes an upper cover piece that covers above the inner barrel; State 1 is the state where the lever member drives the upper cover piece to open, and in this state, the lever member pushes the inner barrel upward to expose the barrel opening; State 2 of the lever member is when the brush rod presses on the lever member, the inner barrel moves downward, and the gravity of the brush rod or the friction between the brush rod and the holes in the barrel base is greater than the elastic force of the spring, and the lever member drives the upper cover piece to cover above the inner barrel to maintain the closed state. The effect is that when taking out the brush rod, the barrel cover automatically opens to expose the cotton head in the inner barrel; when inserting the brush rod back, the barrel cover automatically closes, and the barrel cover does not need to be touched throughout the process.

[0003] Most importantly, there are teeth provided on the barrel cover. When in State 1, the teeth are restricted on the barrel base. The effect is that when the brush rod clamps the cotton head into the inner barrel, there is a downward pressure, and the teeth can prevent the inner barrel from retracting, and also prevent the upper cover piece from hitting the brush rod and problems such as inaccurate clamping of the brush rod. That is, it is a structure for locking the up and down movement of the inner barrel.

[0004] However, it is found in practice that in State 2, the restraining force generated by the structure of the teeth elastically disengaging is too large, and the brush rod needs a sufficient instantaneous force to disengage when pressed down, resulting in poor use feel.

[0036] Figures 2 - 3 As described above, when the present invention is in use, the brush rod 14 automatically opens the barrel lid when it is pulled out of the barrel base 2, and automatically closes the lid when it is inserted. The whole process does not require manual pressing of the barrel lid 1 of the barrel base 2. At the same time, in order to prevent the inner barrel 6 from descending when the brush rod 14 is inserted into the inner barrel 6, a locking structure is provided.

[0037] Figures 1 - 3 As shown, the present invention includes a barrel base 2 provided with a placement area and holes 3. The brush rod 14 can be inserted into the holes 3, and the placement area is provided with an inner barrel 6 that can move up and down. Multiple disposable brush heads are stacked in the inner barrel 6. The placement area is an open area, and a barrel lid 1 is provided on the barrel base 2, and the barrel lid 1 can cover the inner barrel 6.

[0038] A rocker 9 is provided below the inner barrel 6. The rocker 9 can push the inner barrel 6 to move upward, and at the same time can also open the barrel lid 1. The inner barrel 6 is thus exposed at the barrel opening, facilitating the insertion of the brush rod 14 into the inner barrel 6 to pick up the brush head. When the brush rod 14 is stored, it is inserted into the hole 3, and the brush rod 14 will press on the rocker 9 to reset it, and the inner barrel 6 can descend and the barrel lid 1 can be closed.

[0039] Figure 4On both sides of the shown preferred placement area, there are vertical guide grooves. On the side of the inner barrel 6, there are sliding blocks 15 inserted into the guide grooves to determine the stability of the stroke.

[0040] Preferably, the seesaw 9 is hinged below the barrel seat 2. The seesaw 9 is connected to the inner barrel 6 and pushes the inner barrel 6 to move. More preferably, the seesaw 9 is directly connected to the barrel cover 1, and the barrel cover 1 is hinged to the barrel seat 2. The barrel cover 1 includes a side cover part 1-2 and a top cover part 1-1. At the bottom of the side cover, there is a slot, and one end of the seesaw 9 is inserted into the slot. As Figure 8 shown, for the convenience of assembly, the seesaw 9 is fixedly connected to the slot through the buckle 18 at the front end. The side cover is hinged to the seat, and a first spring 8 is provided at the hinge. The first spring 8 is a torsion spring. In the natural state, the barrel cover 1 is kept open by the first spring 8, the side cover is turned to one side, and the top cover also moves out of the range above the inner barrel 6, which will also drive one end of the seesaw 9 to tilt up.

[0041] The seesaw 9 is supported under the inner barrel 6. When one end of the seesaw 9 tilts up, it will surely push the inner barrel 6 to move upward. One end of the seesaw 9 protrudes from below the inner barrel 6 and extends to below the hole 3. The hole 3 communicates with the area where the seesaw 9 is located. One end of the brush rod 14 inserted into the hole 3 can contact the tail end of the seesaw 9. When collecting, the brush rod 14 can be pressed hard to flatten the tilted-up seesaw 9.

[0042] The main features of the present utility model are as follows:

[0043] On the side wall of the inner barrel 6, there is a first locking part 12; on the barrel seat 2, there is a first locking member 13. A second spring is provided on the barrel seat 2 and / or the first locking member 13, and the first locking member 13 can cooperate with the first locking part 12 of the inner barrel 6.

[0044] A part of the first locking member 13 is located below the hole 3. Looking axially down from the hole 3, a part of the first locking member 13 can be seen, that is, the projection of the part of the first locking member 13 on the radial plane of the hole 3 falls within the range of the hole 3. When the brush rod 14 is inserted into the hole 3, the brush rod 14 touches a part of the first locking member 13 and makes it swing back, and the first locking member 13 completes unlocking.

[0045] Specifically, the first locking part 12 is a concave groove. The first locking member 13 includes a hook body, a front hook head 13-2 and a rotating shaft 13-4. A guiding surface 13-1 is provided on the front hook head 13-2, and a blocking part 13-3 is provided on the hook body. The front hook head 13-2 is attached to the outer wall of the inner barrel 6. When the inner barrel 6 moves upward, the front hook head 13-2 falls into the first locking part 12. A torsion spring (second spring) is provided at the rotating shaft 13-4, and the torsion spring drives the front hook head 13-2 of the hook body to keep pressing on the outer wall of the inner barrel 6. The guiding surface 13-1 is provided on the front hook head 13-2 to facilitate falling into the first locking part 12.

[0046] As Figure 3As shown in the figure, it is assumed that the counterclockwise direction of the locking member 13 is the locking direction and the clockwise direction is the opening direction. When the locking member 13 rotates counterclockwise to a certain position, it needs to stop, and it will have a blocking effect only when the inner barrel 6 is pressed down. Therefore, a blocking portion 13-3 is provided on the hook body, and a protruding positioning point 17 is provided on the barrel seat 2. Figures 6 - 7 As shown. During the rotation of the first locking portion 12, the blocking portion 13-3 will touch the protruding positioning point 17 on the barrel seat 2. The maximum rotation angle of the locking member 13 is restricted, and the locking member 13 cannot rotate counterclockwise continuously.

[0047] Figure 4 、 Figure 5 As shown, when the tail end of the rocker 9 is too long, a hollow position 16 is provided on the rocker 9 to avoid the locking member 13. When the rocker 9 tilts up, the locking member 13 passes through the hollow position 16 of the rocker 9.

[0048] When it needs to be closed, as Figure 2 shown, the brush rod 14 is inserted. The brush rod 14 touches the locking member 13, causing the locking member 13 to rotate clockwise. The locking member 13 can disengage from the first locking portion 12, and the inner barrel 6 can descend smoothly.

[0049] Secondly, the locking stability can also be enhanced:

[0050] As Figure 2 、 Figure 5 shown, there is a second locking portion 7 at the bottom of the inner barrel 6. The second locking portion 7 is a concave groove. There is an upward protrusion 10 on the rocker 9 and it is in contact with the bottom of the inner barrel 6. A second locking member 11 is provided on the protrusion 10. When the protrusion 10 of the rocker 9 pushes the inner barrel 6 to rise, the relative position between the protrusion 10 and the bottom of the inner barrel 6 changes, and the second locking member 11 on the protrusion 10 will snap into the second locking portion 7.

[0051] The second locking member 11 includes a plastic elastic sheet body, and a hook portion is provided at one end. The hook portion can hook in the concave groove. When the rocker 9 is pressed down, the second locking member 11 disengages from the second locking portion 7. The second locking member 11 is more likely to elastically deform and disengage.

[0052] The present utility model has a first state. The first state is the state where the rocker 9 drives the top cover part 1-1 to turn over and open. In this state, the rocker 9 pushes the inner barrel 6 to move up to expose the barrel opening. The locking member 13 is snapped into the first locking portion 12 under the action of the second spring to lock the downward movement of the inner barrel 6 under force; when the brush rod 14 clamps the cotton head downward, the downward pressure will not cause the rocker 9 to tilt, preventing the top cover part 1-1 from moving and hitting the brush rod 14, and solving the problem that the brush rod 14 cannot clamp accurately after being hit.

[0053] State 2 is the state where the cleaning rod 14 is stored. The cleaning rod 14 is inserted into the hole 3, the cleaning rod 14 presses on the seesaw 9, a part of the cleaning rod 14 inserted into the hole 3 touches the first locking member 13, the first locking member 13 unlocks from the first locking part 12, the inner barrel 6 moves downward, the gravity of the cleaning rod 14 or the friction between the cleaning rod 14 and the hole 3 of the barrel seat 2 is greater than the elastic force of the first spring 8, and the seesaw 9 drives the top cover part 1-1 to cover above the inner barrel 6 to maintain the sealed state.

[0054] The top cover part 1-1 is also provided with a storage space 5-1 where items such as fragrance agents can be placed. Above the storage space 5-1 is provided with an upper cover 5 with holes 3. On the side of the barrel seat 2 is provided with a hanging seat 4 for hanging on the wall.

[0055] The above has introduced the title provided by the present utility model in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the present utility model and its core idea. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
