Description

Technical Field

[0001] The present invention relates to the field of household appliances, and in particular to a vacuum cleaner and a floor brush structure of the vacuum cleaner. Background Art

[0002] A vacuum cleaner is a household appliance for indoor cleaning. It is mainly used to clean floors, carpets, furniture, etc., and to absorb dust from narrow corners in the home environment. The working principle of a vacuum cleaner is to use an electric motor to drive the fan to rotate at high speed, thereby generating negative pressure to remove dust.

[0003] The suction nozzle of the vacuum cleaner in the prior art can be flexibly rotated at a certain angle during the cleaning process to achieve cleaning of different areas of the environment; in the storage state, in order to save space, it is generally placed upright with the operating rod perpendicular to the suction nozzle and standing in a corner.

[0004] Currently, existing vacuum cleaners on the market generally use a concave-convex structure at the position where the connecting rod and the nozzle match to prevent the operating rod from tipping over to the sides. However, the reliability of the concave-convex structure is poor, and friction marks will appear after a long time of use, affecting the appearance of the vacuum cleaner. Some vacuum cleaners on the market are also not equipped with a structure to prevent tipping over, so that the vacuum cleaner can only be placed horizontally when stored, which takes up a lot of space and is inconvenient to store.

[0005] Therefore, it is necessary to provide a new vacuum cleaner positioning device to ensure the reliability of vacuum cleaner positioning. Summary of the invention

[0006] The main purpose of the present invention is to provide a vacuum cleaner and a floor brush structure of the vacuum cleaner to solve the problem of unreliable positioning of the vacuum cleaner in the prior art.

[0010] Furthermore, a first positioning hole is provided on the connecting rod, and a second positioning hole corresponding to the first positioning hole is provided on the connector. When the connecting rod is in the working position, the positioning member is only located in the second positioning hole. When the connecting rod is in the storage position, the positioning member is simultaneously located in the first positioning hole and the second positioning hole.

[0011] Furthermore, the locking mechanism also includes a rotating shaft connected to the positioning member, and a positioning groove matching the rotating shaft is provided on the inner wall surface of the second positioning hole to support the rotating shaft.

[0012] Furthermore, the connector also includes an end cover, which is arranged on the upper part of the connector and is used to prevent the rotating shaft from falling out of the positioning groove.

[0019] According to another aspect of the present invention, there is provided a vacuum cleaner, comprising a handle and a floor brush structure connected to the handle, wherein the floor brush structure is the above-mentioned floor brush structure.

[0020] By applying the technical solution of the present invention, the locking mechanism is used to switch between the locked position and the unlocked position, so that the connecting rod can be in the storage position and the working position, so that the connecting rod cannot rotate with the connector assembly when it is in the storage position, which is convenient for storage.

[0035] like Figures 1 to 7As shown, the present invention provides a vacuum cleaner. The vacuum cleaner of this embodiment includes a nozzle body 40, a connector assembly, a connecting rod 10 and a locking mechanism. The nozzle body 40 is fixedly connected to the connector assembly, the connecting rod 10 is arranged between the nozzle body 40 and the connector assembly, the first end of the connecting rod 10 is pivotally connected to the nozzle body 40, so that the connecting rod 10 has an upright storage position and a horizontal working position; the second end of the connecting rod 10 is pivotally connected to the connector assembly, so that the connector assembly can swing left and right relative to the connecting rod 10 and the nozzle body 40; the locking mechanism, the locking mechanism is arranged in the connector assembly, the locking mechanism has a locking position and an unlocking position, when the connecting rod 10 is in the storage position, the locking mechanism is in the locking position, so that the second end of the connecting rod 10 and the connector assembly cannot rotate relative to each other, when the connecting rod 10 is in the working position, the locking mechanism is in the unlocking position, so that the second end of the connecting rod 10 and the connector assembly can rotate relative to each other.

[0036] Specifically, in the present application, a locking mechanism is used to switch between a locked position and an unlocked position, so that the connecting rod 10 can be placed in a storage position or a working position, so that the connecting rod 10 cannot rotate with the connector assembly when in the storage position, which is convenient for storage. When the connecting rod 10 is in the working position, the connecting rod 10 can rotate freely with the connector assembly, thereby driving the nozzle body 40 to rotate freely, which is convenient for users to perform cleaning work. The above-mentioned setting method is reliable and simple in structure, and the nozzle body 40 can automatically switch between the unlocked state and the locked state, thereby improving the convenience of product use. Compared with the prior art of setting a convex point on the handle and setting a card position on the nozzle body 40 for card connection, the setting method of the present application has no trace of card connection, and the appearance is more beautiful and the reliability is better.

[0037] like Figure 1 As shown, in an embodiment of the present invention, the connector assembly includes a connector 20 and a hose. The connector 20 is pivotally connected to the second end of the connecting rod 10; and the outlet of the nozzle body 40 is connected to the connector 20 through the hose.

[0038] Specifically, in the present application, one end of the hose is fixedly connected to the outlet of the nozzle body 40 , and the other end of the hose is connected to the connector 20 .

[0039] like Figures 1 to 4 As shown, in the embodiment of the present invention, the locking mechanism includes a positioning member 30, a first end of the positioning member 30 is pivotally connected to the connector 20, and a second end of the positioning member 30 is a free end and can swing back and forth.

[0040] In the present application, when the connecting rod 10 rotates between the storage position and the working position relative to the nozzle body 40, the second end of the positioning member 30 can swing back and forth in the connector 20 as the connecting rod 10 rotates, so that the positioning member 30 locks the connecting rod 10 in the storage position, so that the connecting rod 10 and the connector 20 cannot rotate relative to each other, or the connecting rod 10 is in the unlocked working position, so that the connecting rod 10 can rotate freely relative to the connector 20.

[0041] Preferably, the positioning member 30 is made of plastic, which is low in cost and easy to process.

[0042] Of course, in alternative embodiments not shown in the present invention, the positioning member 30 may also be made of other materials.

[0043] like Figure 1 and Figure 2 As shown, in an embodiment of the present invention, a first positioning hole 11 is provided on the connecting rod 10, and a second positioning hole 21 corresponding to the first positioning hole 11 is provided on the connector 20. When the connecting rod 10 is in the working position, the positioning member 30 is only located in the second positioning hole 21. When the connecting rod 10 is in the storage position, the positioning member 30 is simultaneously located in the first positioning hole 11 and the second positioning hole 21.

[0044] Specifically, the connecting rod 10 is provided with a first positioning hole 11 , the connector 20 is provided with a second positioning hole 21 corresponding to the first positioning hole 11 , and the positioning member 30 is selectively located only in the second positioning hole 21 or in both the first positioning hole 11 and the second positioning hole 21 .

[0045] In the present application, when the positioning member 30 is only located in the second positioning hole 21, as shown in FIG. Figure 7 As shown, at this time, the nozzle body 40 is in an unlocked state, and the nozzle body 40 can rotate relative to the connector assembly, which is convenient for the user to use the vacuum cleaner to clean the environment in all directions; when the positioning member 30 is located in the first positioning hole 11 and the second positioning hole 21 at the same time, as shown in FIG. Figure 6 As shown, at this time, the connecting rod 10 cannot rotate relative to the connector 20, and the nozzle body 40 is in a locked state. At this time, the nozzle body 40 cannot rotate relative to the connector assembly. The user can store the vacuum cleaner in a suitable position and avoid the vacuum cleaner from tipping over due to the rotation of the connector assembly relative to the nozzle body 40. The above arrangement enables the nozzle body 40 to switch between the unlocked state and the locked state according to the different positions of the positioning member 30, and the structure is simple, convenient and reliable.

[0046] like Figures 3 to 5 As shown, in the embodiment of the present invention, the locking mechanism further includes a rotating shaft 31 connected to the positioning member 30 , and a positioning groove 211 cooperating with the rotating shaft 31 is provided on the inner wall surface of the second positioning hole 21 to support the rotating shaft 31 .

[0047] Specifically, the rotating shaft 31 can rotate in the positioning groove 211 to make the positioning member 30 swing back and forth in the second positioning hole 21. When the connecting rod 10 is in the storage position, the connecting rod 10 is placed vertically, and the positioning member 30 naturally droops under the action of its own gravity and is located in the first positioning hole 11 and the second positioning hole 21 at the same time. The positioning member 30 is close to the inner wall of the first positioning hole 11 (such as Figure 6 ), the positioning member 30 is in the locked position, and the connecting rod 10 cannot rotate relative to the connector 20. When the connecting rod 10 rotates from the vertical position to the horizontal position, the positioning member 30 rotates around the rotation axis 31 under the action of its own gravity, swings backward from the inner wall of the first positioning hole 11, and gradually approaches the inner wall of the second positioning hole 21 (as shown in FIG. Figure 7 ), the positioning member 30 gradually moves away from the first positioning hole 11. When the positioning member 30 is completely located in the second positioning hole 21, the positioning member 30 is in the unlocked position, and the connecting rod 10 can rotate relative to the connector 20.

[0048] Through the above arrangement, the positioning member 30 can rotate around the rotating shaft 31 under the action of its own gravity, so that the positioning member 30 automatically switches between the locked position and the unlocked position, so that when the vacuum cleaner is in the storage position, the connecting rod 10 remains in a vertical position, which is convenient for users to store; when the vacuum cleaner is in the working position, the connecting rod 10 can rotate freely relative to the connector 20, so that the nozzle body 40 can rotate flexibly, which is convenient for users to clean the environment. The positioning member 30 can automatically switch positions by gravity when the connecting rod 10 is in different positions, which is convenient, fast and reliable.

[0049] like Figure 2 and Figure 3 As shown, in the embodiment of the present invention, the connector 20 further includes an end cover 22 , which is disposed on the upper portion of the connector 20 to prevent the rotating shaft 31 from escaping from the positioning groove 211 .

[0050] In the present application, the end cover 22 is engaged with the connector 20 to prevent the positioning member 30 from moving up and down in the positioning groove 211 or the rotating shaft 31 from falling out of the positioning groove 211 .

[0051] like Figure 3 and Figure 4 As shown, in the embodiment of the present invention, there are two positioning grooves 211 , and the two opposite ends of the rotating shaft 31 are respectively disposed in the two positioning grooves 211 , so that the positioning member 30 can swing relative to the connector 20 .

[0052] Specifically, Figure 5 As shown, the positioning groove 211 is an arc-shaped groove. The two positioning grooves 211 support the two ends of the rotating shaft 31 so that the rotating shaft 31 can rotate in the positioning groove 211, thereby allowing the positioning member 30 to swing relative to the connector 20.

[0053] Preferably, the positioning groove 211 and the connector 20 are an integrally formed structure. This arrangement is simple and has reliable connection strength.

[0054] Furthermore, the center of gravity of the positioning member 30 is lower than the geometric center.

[0055] Specifically, the center of gravity refers to the equivalent point of gravity of an object. For objects with uniform material and regular shape, the center of gravity coincides with the geometric center. In the present application, in order to ensure that the positioning member 30 can swing around the rotating shaft 31, the positioning member 30 is designed to be a structure with a center of gravity lower than the geometric center, so that the lower weight of the positioning member 30 is greater than the upper weight, so that the positioning member 30 can swing between the first positioning hole 11 and the second positioning hole 21 under the action of its own gravity, and the swinging effect is obvious. Compared with setting the positioning member 30 to be regular in shape and uniform in mass, the positioning member 30 in the present application swings more flexibly under the action of gravity, which helps to switch the positioning member 30 between the locked position and the unlocked position, and the positioning effect is good.

[0056] like Figure 4 As shown, in the embodiment of the present invention, the positioning member 30 includes a positioning body and a weight part, the positioning body has a first end and a second end that are oppositely arranged, the rotating shaft 31 is arranged at the first end, and the weight part is arranged at the second end.

[0057] Preferably, the positioning body, the weight part and the rotating shaft 31 are an integrally formed structure.

[0058] Such arrangement is easy to process and has good connection strength. Of course, in the alternative embodiment shown in the present invention, the rotating shaft 31, the positioning body and the weight part can also be assembled after being processed separately, and the role of the positioning member 30 in the present application can also be achieved.

[0059] In the present application, a weight part is provided at the second end of the positioning body so that the weight of the lower end of the positioning member 30 is greater than that of the upper end, so that the lower end of the positioning member 30 can swing back and forth under the action of gravity.

[0060] Furthermore, in an embodiment of the present invention, the weight of the weight part is greater than the weight of the positioning body.

[0061] Through the above arrangement, the center of gravity of the positioning member 30 is lower than the geometric center of the positioning member 30. Generally speaking, for an object with a regular shape and uniform mass, its center of gravity coincides with the geometric center. In the present application, the positioning member 30 has a regular shape, but since a weight part is provided on the positioning member 30, the weight of the weight part is greater than the weight of the positioning body, the mass distribution of the positioning member 30 is uneven, and its center of gravity position is biased toward one end close to the weight part, so the center of gravity position of the positioning member 30 is lower than the position of its geometric center. Through the above arrangement, the positioning member 30 can rotate around the rotating shaft 31 under the action of its own gravity, so that the positioning member 30 switches between the first positioning hole 11 and the second positioning hole 21, thereby switching the positioning member 30 between the locked position and the unlocked position.

[0062] like Figure 4 As shown, in the embodiment of the present invention, a weight-reducing groove 32 is provided on one end of the positioning member 30 close to the rotating shaft 31 .

[0063] In order to further ensure the rotation effect of the positioning member 30 around the rotating shaft 31, a weight reduction groove 32 is provided at one end of the positioning member 30 close to the rotating shaft 31, so as to further reduce the weight of the first end of the positioning body and make the second end of the positioning body rotate more effectively. At the same time, the provision of the weight reduction groove 32 also saves materials and reduces costs.

[0064] The present application also provides a vacuum cleaner, which includes a handle and a floor brush structure connected to the handle, and the floor brush structure is the above-mentioned floor brush structure.

[0065] The vacuum cleaner floor brush structure of the present application utilizes the gravity of the positioning member 30 to rotate around the rotating shaft 31 to switch between the first positioning hole 11 and the second positioning hole 21, so that the positioning member 30 switches between the locked position and the unlocked position, thereby realizing the positioning of the handle, and the positioning is reliable. Therefore, the vacuum cleaner with the above floor brush structure also has the above advantages.

[0066] In the present application, a second positioning hole 21 is provided on the connector 20 of the vacuum cleaner for accommodating the positioning member 30. Two grooves are provided at both ends of the second positioning hole 21. The two grooves are connected to the rotating shaft 31 of the positioning member 30. An end cover 22 is provided above the positioning member 30. The end cover 22 is fixed on the connector 20 to prevent the positioning member 30 from falling out of the groove.

[0067] When the vacuum cleaner is in use, the connector 20 of the vacuum cleaner rotates from a vertical position to a horizontal position, and the connector 20 tilts toward the ground. Under the action of gravity, the positioning member 30 moves toward the inner wall of the second positioning hole 21 on the connector 20, and the positioning member 30 moves toward the outer wall of the connecting rod 10. The connector 20 can rotate left and right relative to the connecting rod 10.

[0068] When the vacuum cleaner is in the storage position, the connector 20 returns to the upright state from the tilted usage state, and under the action of gravity, the outer wall of the positioning member 30 moves closer to the outer wall of the connector 20, and the inner wall of the positioning member 30 is separated from the inner wall of the connecting rod 10. The positioning member 30 is stuck in the first positioning hole 11 of the connecting rod 10, and the connector 20 cannot rotate left and right relative to the connecting rod 10.

[0069] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the floor brush structure of the vacuum cleaner of the present application includes a nozzle body, a connector assembly, a connecting rod and a locking mechanism. The connector assembly includes a hose and a connector, a first positioning hole is provided on the connecting rod, and a second positioning hole is provided on the connector. When the positioning member is only located in the second positioning hole, the nozzle body is in an unlocked state, at which time the nozzle body can rotate relative to the handle, which is convenient for the user to use the vacuum cleaner to clean all directions of the environment; when the positioning member is located in the first positioning hole and the second positioning hole at the same time, the connecting rod cannot rotate relative to the connector, and the nozzle body is in a locked state, at which time the nozzle body cannot rotate relative to the handle, and the user can store the vacuum cleaner in a suitable position, and avoid the vacuum cleaner from tipping over due to the rotation of the handle relative to the nozzle body. The above-mentioned setting enables the nozzle body to switch between the unlocked state and the locked state according to the different positions of the positioning member, and the structure is simple, convenient and reliable.

[0070] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
