Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more specifically, it relates to a sash assembly, a sash drive module and an automated trash can. Background Technology

[0002] Automated trash cans, as a type of household appliance, are widely used in people's daily lives. Automated trash cans, relying on their automated trash bag packaging and replacement, significantly improve the convenience of using trash cans and also upgrade the traditional way of using them. In the field of automated trash cans, trash bag packaging relies on packaging components (such as two-bar or three-bar packaging) to close the bag opening; therefore, designing a simpler and more reliable packaging structure is of paramount importance.

[0003] The inventors of this case discovered that traditional automated trash cans preferably use two-bar or three-bar strapping components, rather than flexible clamping components. The main reason for this is that the closing state of the clamping component is uncertain, making accurate strapping impossible. If a notch is made on the side of the clamping component, the detection requirements of the position switch can be met, and the depth of the notch has a predetermined requirement to ensure the accuracy of position detection based on the notch. However, the notch design of traditional clamping components significantly affects their structural performance, and the notch design also imposes thickness requirements on the clamping component itself, thus impacting the selection, service life, and performance of the clamping component.

[0036] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0037] A drawstring assembly is used to bind garbage bags, that is, to bind the opening of the garbage bag together to achieve bag binding and packaging.

[0038] Combination Figure 1 As shown, the binding assembly structure is configured to include a binding member 1 and gear teeth 2 attached to the binding member 1. The binding member 1 is strip-shaped and has a preset toughness in a bent state to achieve a preset lifespan for repeated packaging operations.

[0039] The configured gear tooth 2 structure can mesh with a gear. When the gear tooth 2 meshes with the gear, the gear can drive the gear tooth 2 to move the clamping member 1. Since one end of the clamping member 1 in this embodiment is a free end and the other end is a fixed end, the gear driving the gear tooth 2 can move the free end of the clamping member 1. Of course, in other embodiments, both ends of the clamping member 1 can also be set as free ends.

[0040] In this patent, combined with Figure 1 and Figure 2 As shown, the binding member 1 has a first positioning hole 1-1 and a second positioning hole 1-2. The first positioning hole 1-1 is close to the free end of the binding member 1 and is used to achieve a first position positioning of the free end of the binding member 1, which refers to the positioning of the starting position of the binding member packaging. The second positioning hole 1-2 is close to the fixed end of the binding member 1 and is used to achieve a second position positioning of the free end of the binding member 1, which refers to the positioning of the ending position of the binding member packaging.

[0041] Preferably, the inner diameter of the first positioning hole 1-1 and the second positioning hole 1-2 is configured to be between 1mm and 2mm. Furthermore, while ensuring the positioning function is achieved, the smaller the inner diameter of the first positioning hole 1-1 and the second positioning hole 1-2, the better, so as to avoid the impact of opening the first positioning hole 1-1 and the second positioning hole 1-2 on the material properties of the clamping member 1 itself.

[0042] Preferably, the cross-sectional shape of the drawstring member 1 is configured as a rectangle. In other embodiments, the cross-sectional shape of the drawstring member 1 can be configured as a trapezoid, triangle, "D" shape, or any other shape that facilitates its own driving and enables the binding of the garbage bag.

[0043] Meanwhile, in this embodiment, the ferrule 1 is provided with the aforementioned gear tooth 2 on one side. Of course, in other embodiments, the aforementioned gear tooth 2 may optionally appear on both sides or multiple sides. In addition, the fixed end of the ferrule 1 in this embodiment is provided with a fixing block 3, so as to limit and fix the fixed end of the ferrule 1 by means of the fixing block 3.

[0044] Furthermore, and importantly, the ferrule 1 is configured with poor light transmittance. For example, the ferrule 1 can be made of a black / dark-colored material with poor light transmittance, or a thin film with poor light transmittance can be applied to the outer surface of the ferrule 1 to reduce the amount of light transmitted through it. This improves the positioning effect of the first positioning hole 1-1 and the second positioning hole 1-2.

[0045] A nozzle drive module, configured with the aforementioned nozzle assembly, combined with Figures 3-5 As shown, the slit-mouth drive module also includes a housing 4, a drive assembly 5, and a position detection component 6. The housing 4 is used to install the aforementioned slit-mouth assembly and serves as a mounting carrier for the drive assembly 5 and the position detection component 6. The drive assembly 5 is used to drive the free end of the slit-mouth component 1 of the slit-mouth assembly to move. The position detection component 6 is used to locate the starting position and the ending position of the free end of the slit-mouth component 1 of the slit-mouth assembly based on the first positioning hole 1-1 and the second positioning hole 1-2.

[0046] Since the housing 4 is used to install the aforementioned drawstring member, the housing 4 has a first mounting point for installing the fixed end of the drawstring member 1 and a second mounting point for installing the free end of the drawstring member 1. The fixed end of the drawstring member 1 is fixed to the first mounting point, and the free end of the drawstring member 1 is movably limited to the second mounting point. The middle region of the drawstring member 1 between the fixed end and the free end is located outside the housing 4 and on the outer periphery of the garbage bag, so as to enable the binding and packaging of the garbage bag opening.

[0047] In this embodiment, the first mounting point is configured as a slot 4-1 on the housing 4, the slot 4-1 being used to mount the fixing block 3, and the fixing block 3 being mounted in the slot 4-1 by insertion and removal. The second mounting point is configured as a working channel 4-2 in the housing 4 for the free end of the fastening member 1 to pass through, and the free end of the fastening member 1 is located in the working channel 4-2.

[0048] The driving component 5 is used to drive the free end of the mouth-binding member 1 to move in the working channel 4-2, so as to achieve tightening and resetting. Part or all of the driving component 5 is installed inside the housing 4. In this embodiment, the driving component 5 includes a motor 5-1 and a gear set 5-2. The motor 5-1 drives the gear set 5-2 to operate. One gear in the gear set 5-2 meshes with the teeth 2 on the mouth-binding member 1. Specifically, which gear in the gear set 5-2 meshes with the teeth 2 on the mouth-binding member 1 can be determined according to the actual situation. Preferably, the last gear of the gear set 5-2 meshes with the teeth 2. More preferably, the last gear of the gear set 5-2 meshes with the teeth 2 in the channel space of the working channel 4-2.

[0049] The position detection member 6 is used to detect the two in-place positions of the starting position and the ending position of the free end of the mouth-binding member 1 by means of the first positioning hole 1-1 and the second positioning hole 1-2.

[0050] In this embodiment, the position detection member 6 is configured as an opposed photoelectric sensor in the prior art. The difference of this patent is that in this patent, the transmitting tube and the receiving tube of the opposed photoelectric sensor are respectively installed on both sides of the working channel 4-2. When the free end of the mouth-binding member 1 moves in the working channel 4-2, the light emitted by the transmitting tube only passes through the first positioning hole 1-1 and the second positioning hole 1-2, and the receiving tube only receives the light passing through the first positioning hole 1-1 and the second positioning hole 1-2, so as to achieve the purpose of positioning the position of the free end of the mouth-binding member 1.

[0051] Preferably, the opposed photoelectric sensor in this embodiment is configured in a "C" shape. An installation groove 4-3 for installing the position detection member 6 (the opposed photoelectric sensor in a "C" shape) is provided in the housing 4. When the position detection member 6 is installed in the installation groove 4-3, the transmitting tube and the receiving tube of the position detection member 6 are respectively located on both sides of the working channel 4-2.

[0052] This patent also claims to publicly protect an automatic trash can. Combining Figure 1 and Figure 2 as shown, this automatic trash can has the aforementioned mouth-binding driving module, and uses the aforementioned mouth-binding driving module to tie and reset the tying of the garbage bag. In this embodiment, a packing member (such as a hot melt wire) is provided on the mouth-binding driving module. Considering the effect of hot melt sealing of the garbage bag, the smooth surface of the mouth-binding member faces the packing member.

[0053] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
