Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, and in particular to a dust collection component and a dust collector. Background Technology

[0002] As people's living standards improve, their demands for a clean environment also increase, especially in home cleaning, where thorough cleaning of the interior is required. However, traditional methods cannot meet the cleanliness needs of the interior and are time-consuming and laborious. Vacuum cleaners, on the other hand, can effectively and quickly clean stains and dirt, meeting people's requirements. Therefore, they are widely used.

[0003] The dust collection unit is the component in a vacuum cleaner used to collect dust. When the amount of dust reaches the maximum dust collection capacity of the dust collection unit, it needs to be cleaned. Generally, the dust collection unit is designed to be detachable or have a hinged lid. Detachable dust collection units require disassembly before emptying the dust, which is a complicated operation. Hinged dust collection units require manual opening of the lid before emptying the dust, which is more strenuous and may result in the user touching the dust, making emptying the dust less convenient. Summary of the Invention

[0004] Therefore, it is necessary to provide a dust collection device that is easy to empty.

[0005] A dust collection device, comprising:

[0006] A housing having a dust collection chamber, wherein a dust discharge port communicating with the dust collection chamber is provided on the housing;

[0007] A cover that is movably attached to the outer casing is used to open and close the dust outlet;

[0008] The opening mechanism includes a telescopic component and a push rod, one end of the telescopic component is connected to the outer shell, and the other end of the telescopic component is connected to the push rod;

[0009] The opening mechanism has an open state and a locking state. In the open state, the telescopic member is controlled to retract and drives the push rod to drive the cover to open the dust outlet. In the locking state, the push rod is locked, the telescopic member is controlled to retract and is separated from at least one of the outer shell and the push rod under the pulling force of the push rod and the outer shell.

[0010] In one embodiment, the dust collection component includes a first connector and a second connector. The first connector is fixedly connected to the housing and / or the push rod, and the second connector is fixedly connected to the telescopic component. The telescopic component is connected to the housing and / or the push rod through the cooperation of the first connector and the second connector.

[0011] In the clamped state, the first connector is separated from the second connector.

[0012] In one embodiment, both the first connector and the second connector are magnetic connectors, and the first connector and the second connector are connected by magnetic attraction.

[0013] In one embodiment, the dust collection component further includes a limiting component, which is used to limit the movement of the second connecting component relative to the first connecting component to a preset distance, within which there is a magnetic attraction between the first connecting component and the second connecting component.

[0014] In one embodiment, the limiting member has a guide groove, and the second connecting member is slidably disposed in the guide groove.

[0015] In one embodiment, the telescopic component is a shape memory alloy wire, and the telescopic movement of the shape memory alloy wire is controlled by switching the power on and off the wire.

[0016] In one embodiment, one end of the shape memory alloy wire is provided with a positive terminal connected to the positive terminal of the power supply, and the other end of the shape memory alloy wire is provided with a negative terminal connected to the negative terminal of the power supply.

[0017] In one embodiment, the dust collection component further includes an alarm component that generates an alarm signal when the alarm component senses movement of the telescopic component relative to at least one of the housing and the push rod.

[0018] In one embodiment, the cover has a snap fastener, the outer shell has a mating portion that engages with the snap fastener, and the push rod is used to push the snap fastener away from the mating portion.

[0019] In one embodiment, the dust collection component further includes an elastic element, and the outer shell is provided with an abutment portion. The elastic element abuts against the abutment portion and the push rod, and stores the reset potential energy that drives the push rod to move away from the cover when the push rod pushes the cover to open the dust discharge port.

[0020] In one embodiment, the push rod includes a pushing part and a lug protruding from the pushing part. The pushing part is slidably disposed on the outer shell in a direction toward and away from the cover. The lug is disposed at one end of the pushing part away from the cover. The telescopic member extends along the direction of the lug toward the cover, and one end of the telescopic member is connected to the lug, while the other end is fixed to one end of the outer shell where the cover is mounted.

[0021] In one embodiment, the lugs include two lugs, which are distributed on opposite sides of the pushing part along a direction perpendicular to the sliding direction of the pushing part. The telescopic members include two members respectively connected to the two lugs, and the two telescopic members are controlled to extend and retract synchronously.

[0022] A vacuum cleaner comprising the dust collection element described in any one of the above claims.

[0023] The aforementioned dust collection component and vacuum cleaner automatically open the cover via the cover opening mechanism, eliminating the need for users to exert effort in opening the cover and preventing users from touching the dust poured out from the dust outlet during the opening process, making dust emptying quick and convenient; and when the cover opening mechanism is in the locking state, at least one of the telescopic component, push rod, and outer shell is separated, thereby preventing the telescopic component from being pulled off and protecting it.

[0029] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0030] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] See Figure 1 An embodiment of the present invention provides a vacuum cleaner 200, including a gas power mechanism 300 and a dust collection component 100. The gas power mechanism 300 drives airflow into the vacuum cleaner 200 for subsequent air-dust separation. The dust collection component 100 collects the dust formed after separation. When the amount of dust reaches the maximum dust collection capacity of the dust collection component 100, the user can clean the dust inside the dust collection component 100.

[0033] See Figure 2 and Figure 3 The dust collection component 100 includes a housing 10 with a dust collection chamber 11, a cover 20, and a cover opening mechanism 30. The housing 10 has a dust discharge port 12 communicating with the dust collection chamber 11, through which dust can be discharged from the dust collection chamber 11. The cover 20 is movably fitted onto the housing 10 and is used to open and close the dust discharge port 12. When the amount of dust in the dust collection chamber 11 reaches its upper limit, the cover 20 can be opened for cleaning.

[0034] The opening mechanism 30 is located on the outer shell 10 and is used to open the cover 10. In this way, the cover 20 is opened automatically by the opening mechanism 30, so that the user does not need to open the cover with effort. It also prevents the user from touching the dust poured out from the dust outlet 12 during the opening process, making dust removal quick and convenient.

[0035] Optionally, the vacuum cleaner 200 has a dust emptying button on its handle. Pressing the dust emptying button will control the lid opening mechanism 30 to automatically empty the dust.

[0036] See Figure 3Specifically, the cover 20 has a latch 21, and the outer shell 10 has a mating part 13 that engages with the latch 21. The opening mechanism 30 is used to push the latch 21 away from the mating part 13. Thus, by engaging the latch 21 with the mating part 13 on the outer shell 10, the cover 21 is fixedly blocked at the dust outlet 12 of the outer shell 10, sealing the dust outlet 12. When it is necessary to clean the dust collection component 100, the opening mechanism 30 pushes the latch 21 away from the mating part 13, causing the cover 20 to open the dust outlet 12. Optionally, the cover 20 is located in the direction of gravity of the outer shell 10 and is hinged to the outer shell 10. When the latch 21 engages with the mating part 13, the mating part 13 applies a pulling force to the cover 20 in the opposite direction of gravity, so that the cover 20 overcomes its own weight and blocks the dust outlet 12 of the outer shell 10, sealing the dust outlet 12. When the opening mechanism 30 pushes open the latch 21, the latch 21 disengages from the mating part 13, and the cover 20 is no longer pulled by the mating part 13. The cover 20 can rotate downward around the hinge point under its own weight, and at the same time, the dust discharge port 12 is opened to allow dust to be discharged from the dust collection chamber 11.

[0037] Continue reading Figure 2 and Figure 4 The opening mechanism 30 includes a telescopic member 31 and a push rod 32. One end of the telescopic member 31 is connected to the outer shell 10, and the other end of the telescopic member 31 is connected to the push rod 32.

[0038] Specifically, the opening mechanism 30 has an open state and a locking state. In the open state, the telescopic member 31 can be controlled to retract and drive the push rod 32 to abut against the buckle 21 that is engaged with the mating part 13, so as to push the buckle 21 to disengage from the mating part 13. In the locking state, the push rod 32 is locked, the telescopic member 31 is controlled to retract and is separated from at least one of the outer shell 10 and the push rod 32 under the pulling force of the push rod 32 and the outer shell 10.

[0039] If the push rod 32 is jammed during the opening process of the lid opening mechanism 30 (e.g., if the lid 20 is jammed, the push rod 32 will be jammed), the push rod 32 will not move synchronously with the telescopic member 31. At this time, the telescopic member 31 is still retracting. The push rod 32 and the outer shell 10 exert a greater pulling force on the telescopic member 31 to prevent it from retracting further. The greater the amount of retraction of the telescopic member 31, the greater the pulling force exerted by the push rod 32 and the outer shell 10 on the telescopic member 31. Under the action of the above-mentioned pulling force, the telescopic member 31 is easily broken.

[0040] With the above configuration, when the push rod 32 is held, the telescopic member 31 is separated from at least one of the outer shell 10 and the push rod 32 under the pulling force generated by the push rod 32 and the outer shell 10, thereby preventing the telescopic member 31 from being broken under the pulling force exerted on it by the push rod 32 and the outer shell 10 during the contraction process, thus protecting the telescopic member 31.

[0041] It should be noted that, in order to achieve the above effect, the connection force between the component separated from the telescopic member 31 and the telescopic member 31 must be less than the yield tensile force of the telescopic member 31. The yield tensile force of the telescopic member 31 is the limit under the maximum external stress and maintaining the reversible contraction ability.

[0042] In one specific embodiment, when in the latching state, the telescopic member 31 is separated from the outer shell 10, meaning that the connecting force between the telescopic member 31 and the outer shell 10 is less than the aforementioned tensile force. It can be understood that in other embodiments, when in the latching state, the telescopic member 31 may also be separated from the push rod 32, meaning that the connecting force between the telescopic member 31 and the push rod 32 is less than the aforementioned tensile force.

[0043] See Figure 4 The dust collection component 100 includes a first connecting member 40 and a second connecting member 50. The first connecting member 40 is fixedly connected to the outer shell 10, and the second connecting member 50 is fixedly connected to the telescopic member 31. The telescopic member 31 is connected to the outer shell 10 through the cooperation of the first connecting member 40 and the second connecting member 50. In the locked state, the first connecting member 40 and the second connecting member 50 are separated, that is, the telescopic member 31 is separated from the outer shell 10.

[0044] Both the first connector 40 and the second connector 50 are magnetic, and they are connected by magnetic attraction. The magnetic attraction force between the first connector 40 and the second connector 50 can be set to be less than or equal to 70% of the yield stress of the telescopic member 31.

[0045] It is understood that in some other embodiments, the connection method between the first connector 40 and the second connector 50 is not limited. They can be connected to each other without magnetic attraction. That is, any connection method that can ensure that the first connector 40 and the second connector 50 can be connected and fixed when the cover is open and can be detached when the cover is held is acceptable and is not limited here.

[0046] Specifically, the dust collection component 100 also includes a limiting component 60, which restricts the second connecting component 50 from moving relative to the first connecting component 40 to a preset distance. Within this preset distance, there is a magnetic attraction between the second connecting component 50 and the first connecting component 40. That is, the limiting component 60 ensures that the magnetic attraction remains even after the second connecting component 50 and the first connecting component 40 are separated, so that after troubleshooting, the telescopic component 31 can return to its original deformation, and the first connecting component 40 and the second connecting component 50 can be re-engaged for continued use.

[0047] It should be noted that the telescopic component 31 can automatically recover its deformation, or it can recover its deformation through control.

[0048] Furthermore, the limiting member 60 is provided with a guide groove 61, and the second connecting member 50 is slidably disposed in the guide groove 61. When the second connecting member 50 is separated from the first connecting member 40, the second connecting member 50 can move away from the first connecting member 40 under the guidance of the guide groove 61. After the fault is cleared, the second connecting member 50 can also move towards the first connecting member 40 under the guidance of the guide groove 61.

[0049] In some embodiments, the aforementioned telescopic component 31 is a shape memory alloy wire, and its expansion and contraction are controlled by switching electricity on and off. Shape memory alloys are special metallic materials that undergo plastic deformation within a certain temperature range and then recover their original macroscopic shape within another temperature range. When electricity is applied to the shape memory alloy wire, it heats up and contracts; when the electricity is de-energized, the wire's temperature recovers, and the deformation returns to its initial state. Optionally, the shape memory alloy wire is a nickel-titanium alloy wire.

[0050] One end of the shape memory alloy wire is provided with a positive terminal 70 connected to the positive terminal of the power supply, and the other end of the shape memory alloy wire is provided with a negative terminal 80 connected to the negative terminal of the power supply. Thus, a positive power supply lead can be connected to the positive terminal 70, and a negative power supply lead can be connected to the negative terminal 80, connecting the shape memory alloy wire to the circuit of the main control circuit board, so that the power supply to the shape memory alloy wire can be controlled by the circuit of the main control circuit board. Optionally, both the positive terminal 70 and the negative terminal 80 are fastening screws, which are used to fix the shape memory alloy wire. Positive and negative leads can also be connected to the fastening screws to connect the shape memory alloy wire to the positive and negative leads. Furthermore, when the dust emptying button at the handle is pressed, the circuit in the main control circuit board receives a power signal, controlling the shape memory alloy wire to be energized, thereby opening the cover 20.

[0051] The dust collection unit 100 also includes an alarm unit 110, which generates an alarm signal when it senses movement of the telescopic member 31 relative to at least one of the housing 10 and the push rod 32. If the telescopic member 31 moves relative to at least one of the housing 10 and the push rod 32, it indicates a malfunction in the dust collection unit 100 (the cover 20 is stuck), and the alarm unit 110 generates an alarm signal to notify the user to troubleshoot the problem. Specifically, the alarm unit 110 is a Hall sensor.

[0052] Continue reading Figure 3The dust collection component 100 also includes an elastic element 90. An abutment portion 14 is provided on the outer casing 10. The elastic element 90 abuts against the abutment portion 14 and the push rod 32. When the push rod 32 pushes the latch 21 away from the mating portion 13, it stores the reset potential energy that would cause the push rod 32 to move away from the mating portion 13. The elastic element 90 abuts against the abutment portion 14 of the outer casing 10 and the push rod 32 to support the push rod 32. When the push rod 32 slides closer to the mating portion 13 under the action of the telescopic member 31 to push the latch 21 away from the mating portion 13, the elastic element 90 is compressed, storing elastic potential energy. When the latch 21 is pushed open, the telescopic member 31 releases the pulling force on the push rod 32, and the push rod 32 can then move away from the mating portion 13 under the elastic force of the elastic element 90, returning to its initial state.

[0053] In other words, in this specific embodiment, the telescopic member 31 drives the push rod 32 to move closer to the mating part 13, pushing the buckle 21 to disengage from the mating part 13, and the elastic member 90 drives the push rod 32 to move away from the mating part 13, so that the push rod 32 is reset.

[0054] Continue reading Figure 4 Specifically, the push rod 32 includes a pushing part 321 and a lug 322 protruding from the pushing part 321. The pushing part 321 is slidably disposed on the housing 10 in the direction of approaching and moving away from the mating part 13. The lug 322 is disposed at the end of the pushing part 321 away from the mating part 13. The telescopic member 31 extends along the direction of the lug 322 pointing towards the mating part 13, and one end of the telescopic member 31 is connected to the lug 322, while the other end is fixed to the end of the housing 10 where the mating part 13 is disposed.

[0055] Thus, when the telescopic member 31 is retracted in a controlled manner, the end of the telescopic member 31 connected to the lug 322 will move towards the mating part 13 of the outer shell 10, thereby driving the pushing part 321 to slide towards the mating part 13 of the outer shell 10, so as to push the buckle 21 to disengage from the mating part 13.

[0056] Furthermore, the lugs 322 include two lugs, which are distributed on opposite sides of the pushing part 321 along the direction perpendicular to the sliding direction of the pushing part 321. The telescopic members 31 include two members connected to the two lugs 322 respectively, and the two telescopic members 31 are controlled to extend and retract synchronously. That is, two telescopic members 31 are respectively provided on both sides of the pushing part 321. When the two telescopic members 31 extend and retract synchronously, they can simultaneously apply a pulling force to the push rod 32, so that the push rod 32 can be subjected to a greater pulling force, thereby generating a greater pushing force on the buckle 21, making it easier for the buckle 21 to disengage from the mating part 13.

[0057] In one embodiment of the present invention, a dust collection component 100 included in the above-mentioned vacuum cleaner 200 is also provided. The dust collection component 100 can realize automatic dust emptying, which is convenient to operate. Moreover, the structural design of the dust collection component 100 can protect the telescopic component 31 and prevent the telescopic component 31 from breaking when the dust collection component 100 malfunctions.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
