Description

Technical Field

[0001] The present invention relates to the technical field of vacuum cleaners, and in particular to a mechanism for a door switch, a dust cup mechanism of a vacuum cleaner, and a vacuum cleaner. Background Art

[0002] Most existing vacuum cleaners require a locking structure between the dust cup cover and the cup body, and a torsion spring is provided at the rotating shaft of the cover body, and the torsion spring is used to always apply an opening force to the cover body. When the dust cup needs to be opened, the locking structure between the dust cup and the cover body is in an unlocked state. For ease of use, most of them have a one-button unlocking function to open the cover body.

[0003] However, when closing the cover, it is usually necessary to manually touch the cover and put it back on the dust cup. However, after pouring out the dust in the dust cup, the outer surface of the cover is always in contact with the dust to a greater or lesser extent. Therefore, if a person directly touches the cover to close the door, it is very easy to get the hand dirty, affecting the user experience. In addition, during the operation of the vacuum cleaner, since the locking switch of the dust cup cover is mostly arranged in the area near the outside of the dust cup, it affects the appearance of the dust cup (due to the locking structure of the cup cover, the outer surface of the dust cup near the end of the cup cover cannot present a smooth and flat appearance), and the user may accidentally touch the locking switch of the cup cover, causing the cover to open when it is not necessary. Summary of the invention

[0004] In order to solve the above technical problems, one of the objects of the present invention is to provide a mechanism for door opening and closing, comprising a rotating shaft, which is connected to the door body and can be opened and closed when the rotating shaft is rotated, and a rotating shaft gear is provided in at least a part of the circumferential direction of the rotating shaft; the mechanism for door opening and closing also includes: a first tooth portion, which is meshed with the rotating shaft gear of the rotating shaft; when the first tooth portion moves in a first direction, the door body opens, and when the first tooth portion moves in a second direction, the door body closes; a toggle member, which can drive the first tooth portion to move along the first direction or the second direction, and when the toggle member is toggled in the first direction, the door body closes, and the moving direction of the toggle member is consistent with the opening and closing direction of the door body.

[0005] The door opening and closing mechanism of the present invention has the following beneficial effects: ① The present invention utilizes the toggle member to drive the movement of the first tooth portion meshing with the shaft gear, and only needs to control the movement of the toggle member to realize the opening and closing of the door body, without the user's hands touching the contaminated door body, thereby reducing the trouble and annoyance of the user's hands being contaminated; ② The solution of the present application does not need to set any locking structure at the end of the dust cup close to the door body, which not only avoids the user accidentally touching the locking structure and causing the door body to be opened unnecessary times, but also does not need to set a locking structure on the outer surface of the dust cup, and its appearance is neat and smooth.

[0006] ③ The mechanism for door switch of the present application satisfies the user's operating habits to the greatest extent by keeping the moving direction of the toggle piece consistent with the opening and closing direction of the door. It only provides a first tooth portion meshing with the shaft gear and a toggle piece for driving the first tooth portion to move, thereby keeping the opening and closing trend direction of the door consistent with the toggle direction of the toggle piece. It conforms to the instinctive judgment of the human body and is more convenient for users to use.

[0007] Furthermore, the first tooth portion is a linear tooth. The present application sets the tooth portion meshing with the shaft gear to be linear, so that only a unidirectional force in the horizontal or vertical direction is converted into a rotational force on the shaft, which is more convenient for applying force and saves more effort when the user applies force manually.

[0008] Furthermore, it also includes a second tooth portion capable of driving the first tooth portion to move, and the toggle member is provided with a toggle tooth portion meshing with the second tooth portion. Therefore, by rotating the toggle member, the second tooth portion can move under the action of the toggle tooth portion, thereby driving the movement of the first tooth portion.

[0009] Furthermore, the second tooth portion is a linear tooth, and the second tooth portion and the first tooth portion are arranged in parallel or on the same straight line. Therefore, the rotational force on the rotating shaft can be achieved by the driving force on the linear direction of the second tooth portion, which is more labor-saving and convenient for setting the transmission structure.

[0010] Furthermore, the second tooth portion and the first tooth portion are disposed on the adjustment rod together. Therefore, by toggling the toggle member, the second tooth portion meshing with the toggle member will move accordingly, and further drive the movement of the first tooth portion, thereby driving the rotating shaft meshing with the first tooth portion to rotate, thereby realizing the opening and closing of the door body.

[0011] Furthermore, the first tooth portion is arranged on the first surface of the adjusting rod, and the second tooth portion is arranged on the second surface of the adjusting rod. The first tooth portion and the second tooth portion are arranged on the first surface and the second surface respectively, in order to meet the installation environment of the adjusting rod and avoid the limitation of the installation space. The first tooth portion and the second tooth portion are arranged on two separate surfaces, which does not strictly mean that the two are not on the same plane, but means that the two are in two different areas. This is because the structure of the gear shaft needs to cooperate with the first tooth portion, and the structure of the toggle member needs to cooperate with the second tooth portion. Therefore, this structural setting is to facilitate the installation and setting of the mechanism of the present invention. When the first surface and the second surface are respectively located on different surfaces of the adjusting rod, the setting direction of the force application part for the movement of the adjusting rod can be changed. The force applied to the first surface is converted into the force applied to the surface connected thereto, so that the flexibility and convenience of installation in actual use can be increased, and the change or adjustment of the shape of the component can be minimized.

[0012] Furthermore, the door also includes an adjustment slot for limiting the adjustment rod, thereby ensuring a smooth movement of the adjustment rod, thereby ensuring stability when adjusting the door body to open or close.

[0013] Furthermore, the toggle member limiting part of the present invention does not need to be limited when the door is opened, but limits the toggle member when the door is closed, thereby preventing the door from being opened by mistake when the door needs to be closed, causing dust leakage. Furthermore, the toggle member limiting portion is an abutting edge that can abut against the toggle member, and the abutting edge gradually protrudes along the first direction toward the direction close to the toggle member. Therefore, when the toggle member is toggled toward the first direction, the toggle member can abut against the abutting edge to clamp the toggle member. On the contrary, when the door body is opened, no limiting or clamping is required, and the size of the door body opening depends on the size of the distance moved by the first tooth portion. Therefore, the present invention can easily achieve the effect of clamping and fixing the toggle member in the closed state by simply setting an abutting edge that gradually protrudes along the first direction toward the direction close to the toggle member, but will not interfere with the movement of the door body when the door is opened, and there is no need to set a limiting structure, and the structural setting is simple.

[0014] Furthermore, it also includes a toggle knob connected to the toggle member, and at least a portion of the toggle knob protrudes from the outer surface of the vacuum cleaner. Therefore, the external form of the toggle knob facilitates the user to directly operate and adjust the vacuum cleaner outside.

[0015] Furthermore, the toggle knob includes a knob plate body vertically arranged with the adjustment slot, and a knob connecting plate vertically arranged with the knob plate body, and the knob connecting plate is rotatably connected with the toggle member. The present application can make the toggle knob and the toggle member in a relatively flexible connection state by setting the knob connecting plate, but under the guidance of the slide slot, the knob connecting plate cannot have an excessively large swing angle relative to the toggle member, so that when the user pushes the toggle knob, it feels more relaxed and flexible, and not stiff.

[0016] Furthermore, the toggle member is a rod body that is hinged or abutted against a structural member on which the first tooth portion is arranged. Therefore, by rotating the toggle member, the first tooth portion can be moved and adjusted in the first direction or the second direction.

[0017] The second object of the present invention is to provide a dust cup mechanism of a vacuum cleaner, which includes the aforementioned mechanism for door opening and closing, and the cup cover of the dust cup is connected to the rotating shaft. The dust cup mechanism of the present invention does not require the user to touch the cup cover of the dust cup when closing the door, and the door can be easily opened and closed by only pushing the toggle member in a straight line. The vacuum cleaner can be controlled by one-touch push not only when the cover of the dust cup is opened, but also when the cover is closed. The user has a very high sense of operation and comfort when using it. And when closing the dust cup cover, there is no need for the user to touch the dust-stained cover with his hands.

[0018] Furthermore, it also includes a mounting shell for setting the mechanism for the door switch, the mounting shell is connected to the dust cup, and the toggle member is rotatably connected to the mounting shell.

[0019] Furthermore, the mounting housing has a first connection surface disposed on a side close to the dust cup, and a second connection surface connected to the first connection surface, the second connection surface is disposed in an area close to the side of the dust collection duct, and a slide groove disposed along the first direction or the second direction is disposed on the second connection surface. Therefore, it is convenient to toggle the toggle member along the slide groove, and it is convenient to set the toggle knob.

[0020] Furthermore, the second connecting surface is connected to the first connecting surface via a snap-in piece, one end of the snap-in piece has a bent latch tongue, an inwardly concave latch groove is provided on the first connecting surface, a slot for the bent latch tongue to be inserted into the side wall of the latch groove is provided, and the other end of the snap-in piece has a snap joint that can be inserted into the second connecting surface. The present application sets the mounting shell as a structural form of the first connecting surface and the second connecting surface in order to facilitate the installation and setting of the mechanism for the door body switch of the present invention. The present application achieves the effect of connecting the mounting shell and the connecting shell through the setting of the snap-in piece without affecting the setting of other structures. The present application does not have a significant impact on the original structure and appearance of the vacuum cleaner because of the setting of the mechanism for the door body switch.

[0021] The third object of the invention is to provide a vacuum cleaner, which includes the aforementioned mechanism for door opening and closing or the aforementioned dust cup mechanism of the vacuum cleaner. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0024] Embodiment 1: See also Figure 1 and Figure 2 As shown, this embodiment is a mechanism for door body switch, including a rotating shaft 2 connected to the door body 1, and a rotating shaft gear 21 is provided in at least a part of the circumferential direction of the rotating shaft 2; the mechanism for door body switch of this embodiment also includes a first tooth portion 41 that can mesh with the rotating shaft gear 21 on the rotating shaft 2 and a toggle member 3 that can drive the first tooth portion 41 to move along the first direction A or the second direction B. The toggle member 3 is rotatably arranged through the toggle shaft 31, and by rotating the toggle member 3, the movement of the first tooth portion 41 can be driven, and the clockwise and counterclockwise rotation of the rotating shaft 2 can be further driven, thereby driving the door body 1 connected to the rotating shaft 2 to open and close.

[0025] In some embodiments, see Appendix Figure 2 As shown, the first tooth portion 41 moves in the first direction A ( Figure 2 When the first tooth portion 41 moves in the second direction B (the direction indicated by the solid arrow A in the middle), the rotating shaft 2 rotates clockwise to achieve the effect of opening the door body 1; on the contrary, when the first tooth portion 41 moves in the second direction B ( Figure 2 When the door body 1 moves in the direction indicated by the solid arrow B in the figure, the door body 1 is closed.

[0026] Therefore, the present invention does not need to touch the door body 1, but directly controls the opening and closing of the door body 1 by applying force to the first tooth portion 41 through the structure of the first tooth portion 41 meshing with the rotating shaft 2, thereby solving the problem that in some cases it is inconvenient to directly touch the door body 1 but the door body 1 needs to be opened and closed.

[0027] See attached Figure 2As shown, in some embodiments, using the mechanism for door opening and closing of the present invention, when the toggle member 3 is toggled in the first direction A, the door 1 is closed; when the toggle member 3 is toggled in the second direction B, the door 1 is opened. Figure 2 The closing direction of the door body 1 is counterclockwise, which is consistent with the first direction A; Figure 2 The direction in which the door body 1 opens is the clockwise direction, which is consistent with the second direction B. The "consistent" here does not mean that the opening and closing direction of the door body 1 is completely consistent with the first direction A or the second direction B. Instead, when a force is applied to the door body 1 along the first direction A, the door body 1 will rotate toward the first direction A and be closed; when a force is applied to the door body 1 along the second direction B, the door body 1 will rotate toward the second direction B and be opened.

[0028] This structure is completely different from the structure in the prior art. Usually, in order to realize the movement of the first tooth portion 41 in the first direction A and the second direction B, the first tooth portion 41 or the structure provided therein can be directly pulled. However, this will cause a problem. When the first tooth portion 41 is pulled in the first direction A, the door body 1 will open, that is, it will open in the direction opposite to the first direction A. This is contrary to the user's usage habits. If the user wants to open the door body 1, he will instinctively apply force in the second direction B. However, if there is no toggle member 3 structure, the door body 1 will be tightly closed at this time. Therefore, the present application can form a mechanism for opening and closing the door body 1 with a simple structure but in line with the user's usage habits through the cooperation of the toggle member 3, the first tooth portion 41 and the shaft gear 21 structure on the shaft 2. Moreover, the present application realizes multiple functions by setting two tooth portions on a structural member (adjusting rod 4). Therefore, within the limited setting space of the original vacuum cleaner structure, without affecting the original structural design of the vacuum cleaner, the present application realizes the effect of closing the cover without touching it by hand.

[0029] In some embodiments, the rotating shaft 2 is pivotally connected to a cylinder, a cup, or other structural members on which the door body 1 is disposed.

[0030] In some embodiments, the shaft gear 21 disposed on the shaft 2 may be a standard shaft gear 21 with a 360-degree circle around the shaft 2, or an arc-shaped shaft gear 21 with a smaller area than 360 degrees, while other areas of the shaft 2 may be conventional cylindrical outer surfaces.

[0031] In some embodiments, the shaft gear 21 disposed on the shaft 2 can be realized by a gear mounted on a standard cylindrical shaft, or a tooth structure is directly formed on the surface of the standard shaft 2 to form the shape of the shaft gear 21 .

[0032] In some embodiments, the first tooth portion 41 is a linear rack. Therefore, the door body 1 can be rotated by applying a force along the linear direction to the first tooth portion 41, which reduces the force applied by the user and facilitates the installation and configuration of the mechanism for the door body switch of this embodiment. In other possible embodiments, the first tooth portion 41 can also be an arc-shaped rack or a shaft gear 21, as long as the effect of meshing and rotating the shaft gear 21 on the shaft 2 can be achieved.

[0033] In some embodiments, the mechanism for door body opening and closing further includes a second tooth portion 42, and a toggle tooth portion meshing with the second tooth portion 42 is provided on the toggle member 3. The second tooth portion 42 is a linear tooth, and the second tooth portion 42 and the first tooth portion 41 are arranged in parallel with each other. The second tooth portion 42 and the first tooth portion 41 are arranged together on the adjustment rod 4. Therefore, by toggling the toggle member 3, the second tooth portion 42 meshing with the toggle member 3 will move accordingly, and further drive the movement of the first tooth portion 41, thereby being able to drive the rotation shaft 2 meshing with the first tooth portion 41 to rotate, thereby realizing the opening and closing of the door body 1.

[0034] See attached Figure 3 As shown, in some embodiments, the first tooth portion 41 is disposed on the first surface 43 of the adjusting rod 4, and the second tooth portion 42 is disposed on the second surface 44 of the adjusting rod 4. In some embodiments, the second tooth portion 42 is located on the side of the adjusting rod 4 close to the user, and no other part structure other than the mechanism for the door body switch is required to be disposed on the surface where the second tooth portion 42 is located. Therefore, this arrangement is to match the installation environment of the mechanism for the door body switch of this embodiment. That is, the second surface 44 can be the same surface as the first surface 43 or a surface parallel to each other; it can also be a surface different from the first surface 43 or a surface not parallel to the first surface 43, for example, a surface perpendicular to the first surface 43 or a surface having a certain angle therewith.

[0035] In some embodiments, the first tooth portion 41 and the second tooth portion 42 are respectively disposed close to two ends of the adjusting rod 4 that are away from each other, thereby reducing the force exerted by the hand during pushing, and facilitating operation by the user.

[0036] In some embodiments, the second tooth portion 42 is a linear tooth. Therefore, it is convenient for the user to apply force by simply adjusting it horizontally or vertically in the first direction A or the second direction B. Compared with the rotational force application method, this linear adjustment force application method is more convenient for the user to pull and is more labor-saving when used. The use of the toggle member 3 in the present application can bring about the effect of increasing the force arm, making the movement process of the second tooth portion 42 easier.

[0037] In other possible implementations, the second tooth portion 42 is on the same straight line as the first tooth portion 41, that is, the first tooth portion 41 and the second tooth portion 42 are teeth on the same straight line. In this case, it is necessary to consider the arrangement of the setting position of the shaft gear 21 meshing with the first tooth portion 41, the setting position of the toggle member 3 meshing with the second tooth portion 42, and the setting position of the dust cup, as long as they do not interfere with each other.

[0038] In some implementations, the mechanism for door opening and closing of this embodiment further includes a toggle member limiting portion. The toggle member limiting portion of this embodiment can achieve the effect of not limiting the toggle member 3 when the door 1 is opened, but limiting the toggle member 3 when the door 1 is closed, thereby preventing the door 1 from being accidentally opened when the door 1 needs to be closed, thereby preventing dust from leaking. See attached Figure 4 and attached Figure 5 As shown, in some embodiments, the toggle member limiting portion is an abutting edge 5 that can abut against the toggle member 3, and the abutting edge 5 gradually protrudes toward the toggle member 3 along the first direction A. Therefore, when the toggle member 3 is toggled in the first direction A, the toggle member 3 can abut against the abutting edge 5 to clamp the toggle member 3. Therefore, when the door body 1 is closed, the position of the toggle member 3 is fixed, and the door body 1 will not be closed firmly and accidentally opened.

[0039] In some embodiments, an adjustment slot 12 is further included for limiting the adjustment rod 4 (see attached Figure 6 and attached Figure 7 As shown). Thus, the movement process of the adjusting rod 4 can be ensured to be smooth, thereby ensuring the stability when the door body 1 is opened and closed.

[0040] In some embodiments, a toggle knob 7 connected to the toggle member 3 is further included, and at least a portion of the toggle knob 7 protrudes from the outer surface of the vacuum cleaner. Therefore, the external form of the toggle knob 7 facilitates the user to operate and adjust directly outside the vacuum cleaner.

[0041] See attached Fig.11As shown, in some embodiments, the toggle knob 7 includes a knob plate body 71 vertically arranged with the slide slot 821, and a knob connecting plate 72 vertically arranged with the knob plate body 71, and the knob connecting plate 72 is rotatably connected with the toggle member 3. And the pin 73 connecting the knob connecting plate 72 with the toggle member 3 is along the first direction A or the second direction B. Therefore, the knob connecting plate 72 can be rotated to a position that is in the same plane or parallel to the toggle member 3. By setting the knob connecting plate 72, the toggle knob 7 and the toggle member 3 can be in a relatively flexible connection state, but under the guidance of the slide slot 821, the knob connecting plate 72 cannot have an excessive swing angle relative to the toggle member 3, so that when the user pushes the toggle knob 7, it feels more relaxed and flexible, not stiff.

[0042] In other possible implementations, the toggle member 3 may also be a rod body directly hinged to the adjustment rod 4. Therefore, by rotating the toggle member 3, the movement and adjustment of the toggle rod 3 in the first direction A or the second direction B can be achieved.

[0043] Embodiment 2: The present embodiment is a dust cup mechanism of a vacuum cleaner, which includes the mechanism for door opening and closing of the first embodiment, wherein the cup cover of the dust cup is connected to the rotating shaft 2, and the rotating shaft 2 is pivotally connected to the end of the dust cup where the cup cover is arranged.

[0044] In some embodiments, it also includes a mounting shell 8 for setting the aforementioned mechanism for the door body switch, the mounting shell 8 is connected to the dust cup, the toggle member 3 is rotatably connected to the mounting shell 8, and the adjustment groove 12 can also be set on the mounting shell 8.

[0045] In some embodiments, the mounting housing 8 has a first connection surface 81 disposed on a side close to the dust cup, and a second connection surface 82 connected to the first connection surface 81. The second connection surface 82 is disposed in a region close to the side of the dust collection duct 10, and a slide groove 821 disposed along the first direction A or the second direction B is disposed on the second connection surface 82. Therefore, it is convenient to toggle the toggle member 3 along the slide groove 821, and it is convenient to set the toggle knob 7.

[0046] See attached Figure 6 and attached Figure 7As shown, in some embodiments, the dust cup and the dust suction pipe 10 are respectively arranged on both sides of the first connection surface 81, and the slide groove 821 is arranged on the second connection surface 82. Accordingly, the mechanism for the door body switch is also arranged on the same side as the dust suction pipe 10, and the mechanism for the door body switch is arranged between the dust suction pipe 10 and the dust cup, and the adjustment groove 12 is arranged between the dust cup and the dust suction pipe 10. Accordingly, the first tooth portion 41 is located between the dust cup and the dust suction pipe 10, and can be meshed with the shaft gear 21 coaxially connected to the shaft 2 of the dust cup. With this structure, the original setting structure between the dust cup mechanism and the dust suction pipe 10 of the vacuum cleaner and the space between the two are cleverly utilized, and no excessive cumbersome structure is added to the overall appearance of the vacuum cleaner, and the vacuum cleaner has a refreshing visual effect.

[0047] In some embodiments, the device further comprises a connecting shell 9 for forming a dust collection duct 10 (see the attached Figure 7 As shown in FIG. 1 ), the second connection surface 82 is connected to the connection housing 9 or is a part of the connection housing 9, and the second connection surface 82 is connected to the first connection surface 81 via a clamping member 6. Figure 8 As shown, one end of the clamping member 6 has a bent clamping tongue 61, a concave clamping groove 62 is provided on the first connecting surface 81, and a clamping groove 621 for the bent clamping tongue 61 to be clamped into is provided on the side wall of the clamping groove 62. After the bent clamping tongue 61 is clamped into the clamping groove 621, it is just accommodated in the concave clamping groove 62 of the first connecting surface 81 (see the attached Fig. 9 and 10 As shown), it does not affect other structures (such as dust cup) set on the surface of the first connecting surface 81. The other end of the clamping member 6 has a clamping joint that can be clamped into the second connecting surface 82. Correspondingly, a clamping groove for accommodating the clamping joint is also provided on the second connecting surface 82. The present application sets the mounting shell 8 as a detachable structural form of the first connecting surface 81 and the second connecting surface 82, so as to facilitate the quick detachable connection of the first connecting surface 81 and the second connecting surface 82 after the mechanism for the door body switch is set on the first connecting surface 81, so as to facilitate installation. But at the same time, it is also necessary to consider the fixing effect of the two in a limited space, and the clamping member 6 can quickly realize the clamping of the first connecting surface 81 and the second connecting surface 82, and then connect the first connecting surface 81 to the connecting shell 9, thereby realizing compact and convenient installation and fixation of the mounting shell 8 and the connecting shell 9.

[0048] In some embodiments, a through mounting hole 91 (see Figure 6 As shown), it is convenient to connect the connecting shell 9 with the mounting shell 8.

[0049] In some embodiments, the middle portion of the clamping member 6 has an escape portion 63 that is bent toward a side away from the dust cup, thereby reserving installation space for setting the first connecting surface 81.

[0050] Embodiment three: This embodiment is a vacuum cleaner, which includes the mechanism for door opening and closing of the first embodiment or the dust cup mechanism of the vacuum cleaner of the second embodiment.

[0051] The above implementation modes are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
