Description

Technical Field

[0001] This application relates to the field of environmental protection equipment technology, and more specifically, to a trash can. Background Technology

[0002] A trash can, also known as a waste bin or garbage can, is a container for holding garbage. Most are made of metal or plastic. When in use, a plastic bag is placed inside, and when there is too much garbage, the bag can be tied up and thrown away.

[0003] However, current trash cans have a relatively limited function, only able to collect trash, and do not have the ability to treat odors from the trash can. Summary of the Invention

[0004] The purpose of this application is to provide a trash can that can more effectively isolate odors.

[0005] In a first aspect, embodiments of this application provide a trash can, comprising: a shell assembly including a shell body, a shell cover, and a trash can; the shell body having a channel arranged along a first direction, one end of the channel being configured as an inlet and the other end as an outlet; the shell cover being connected to one side of the shell body for opening or closing the inlet; the trash can being disposed in the channel for providing a trash bag; and a closing assembly including a closing member and a switch member; the closing member being disposed in the outlet; the switch member being connected to the closing member for controlling the closing member to open or close; wherein when the closing member is open, trash passing through the trash can falls into the trash bag; and when the closing member is closed, it clamps the trash bag.

[0006] In the above-mentioned process, the channel of the main body of the shell is equipped with a garbage box, the shell cover is located on the inlet side of the main body of the shell, and the closing component is located on the outlet side of the main body of the shell. When garbage needs to be disposed of, the shell cover is opened first, and the garbage falls into the closing component after passing through the garbage box. At this time, the closing component can be in a closed state. Then, the inlet is closed by the shell cover, and the closing component is opened by the switch. After the garbage falls into the garbage bag, the closing component clamps the garbage bag. The whole process can be carried out without the shell cover being open, which effectively reduces the odor from the garbage bag and achieves odor isolation.

[0007] In some embodiments, the closing member includes a first closing door and a second closing door, and the switching member includes a first switch and a second switch. The first switch is connected to the first closing door, and the second switch is connected to the second closing door. When the first switch and the second switch are close to each other, the first closing door and the second closing door are far apart from each other. When the first switch and the second switch are far apart from each other, the first closing door and the second closing door are close to each other.

[0008] In the above process, the first closing door is controlled by the first switch and the second closing door is controlled by the second switch. When it is necessary to put garbage into the garbage bag, it is only necessary to control the first switch and the second switch to move closer to each other. After the garbage enters the garbage bag, the first closing door and the second closing door can automatically return to their original positions, thus clamping the garbage bag and effectively reducing the odor from the garbage bag, thereby isolating odors.

[0009] In some embodiments, the first closing door is provided with a first engaging portion, the second closing door is provided with a second engaging portion, and the first engaging portion is configured to engage with the second engaging portion.

[0010] In the above process, the first closing door and the second closing door mesh with each other, which can ensure that after the user operates the first switch and the second switch, the first closing door and the second closing door will rotate synchronously, while effectively improving the stability of the structure and the clamping tightness of the garbage bag when the closing component is closed.

[0011] In some embodiments, one end of the closing member is fitted to the main body of the housing, and the other end extends along the direction away from the main body of the housing and approaches the central axis of the closing member. This not only facilitates the clamping of the garbage bag, but also helps the garbage fall into the garbage bag after the user disposes of it, reducing the degree of contamination of the closing member by the garbage and reducing odor leakage.

[0012] In some embodiments, the closing component is rotatably connected to the housing body. This allows the user to control the closing component via a switch, and the closing component can automatically close after the user releases the switch, thus sealing the garbage bag.

[0013] In some embodiments, the trash can further includes a cutting assembly connected to the housing body near the switch element for cutting the trash bag.

[0014] In the above-mentioned process, the cutting component and the switch are located on the same side of the housing body. This not only allows for cutting garbage bags without excessively stretching them, thus preventing the garbage can from tipping over or falling over when cutting the garbage bag, but also makes the operation more convenient and user-friendly.

[0015] In some embodiments, the housing cover includes a first cover and a second cover, the first cover being fitted onto the housing body, and the second cover being located on the side of the first cover opposite to the housing body.

[0016] In the above implementation process, the first cover is connected to the main body of the housing and can guide the garbage into the inner cavity of the garbage box when the user throws the garbage. The second cover is connected to the main body of the housing and can be used to cover the side of the housing assembly near the inlet, which is conducive to achieving multiple seals of the garbage bag and reducing gas leakage when throwing garbage.

[0017] In some embodiments, the housing assembly further includes a receiving housing connected to the side of the housing body near the outlet, and the receiving housing is configured with a storage space for receiving a portion of the structure of a garbage bag passing through the closing member.

[0018] In some embodiments, the housing assembly further includes a cover door connected to the receiving housing for removing the garbage bag.

[0019] In some embodiments, the housing assembly further includes a support base connected to the side of the housing opposite to the housing body.

Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0029] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts.

[0030] In existing products, ordinary lids are usually provided to cover the opening at the top of the trash can. However, these lids are usually not very effective at sealing, which can easily lead to odor leakage and a poor user experience. Although sealing lids have been improved since then, while they can prevent odor leakage when closed, the odor will still leak out when the user opens the lid to dispose of the trash. This is particularly problematic in enclosed spaces, such as in the winter and summer when users are using air conditioning at home. If odors leak out when the trash can lid is opened, it will be difficult for them to dissipate in time.

[0031] To address this deficiency, this application not only achieves a first seal through the housing cover 102, but also adds a sealing component 20 to achieve a second seal, which can more effectively isolate odors and solve the problem of malodorous gas leakage when users open the cover and dispose of garbage again.

[0032] like Figures 1-5As shown, in a first aspect, this application provides a trash can, including: a shell assembly 10 and a closing assembly 20. The closing assembly 20 is connected to the shell assembly 10. A trash bag inside the shell assembly 10 passes through the closing assembly 20 and extends to the bottom of the closing assembly 20. Thus, when the closing assembly 20 is closed, it can clamp the trash bag. After the user disposes of trash on the side of the shell assembly 10 away from the downward extension direction of the closing assembly 20, the user closes the opening at the top of the shell assembly 10. Then, the user operates the closing assembly 20 to open it, so that the trash falls into the trash bag under its own weight, completing the disposal of trash. Afterward, the user releases the closing assembly. The closing component 20 returns to a closed state. It can be understood that after opening the inlet of the housing component 10 to dispose of garbage, and after disposing of garbage and closing the inlet of the housing component 10 before operating the closing component 20, the closing component 20 can always remain closed. This means the entire operation takes very little time, and the garbage disposal action does not need to be performed with the closing component 20 open. This prevents the leakage of complex odors such as garbage smells and fermentation odors stored in the garbage bag below, resulting in minimal odor emanating from the garbage bag and greatly improving the user experience.

[0033] Specifically, the housing assembly 10 includes a housing body 101, a housing cover 102, and a trash can 103. The housing body 101 has a channel arranged along a first direction, with one end of the channel configured as an inlet and the other end configured as an outlet. The housing cover 102 is connected to one side of the housing body 101 and is used to open or close the inlet. The trash can 103 is arranged in the channel and is used to provide trash bags (storing trash bags in a stacked manner). The closing assembly 20 includes a closing member 201 and a switch member 202. The closing member 201 is arranged at the outlet, and the switch member 202 is connected to the closing member 201 and is used to control the opening or closing of the closing member 201. When the closing member 201 is open, the trash passing through the trash can 103 falls into the trash bag. When the closing member 201 is closed, it is used to clamp the trash bag, and the trash is held / supported above the closing member 201 and cannot fall. A rectangular window is also provided on the front side of the housing body 101, and one end of the switch 202 extends out of the housing body 101 through the rectangular window for easy manual operation.

[0034] For example, the first direction includes, but is not limited to, the vertical direction. The upper end of the housing body 101 is provided with an inlet, and the lower end is provided with an outlet. The housing cover 102 is connected to the upper end of the housing body 101. The connection method can be a rotatable connection. At the same time, when the housing cover 102 closes the inlet of the housing body 101, the periphery of the housing cover 102 is in sealed contact with the housing body 101, ensuring that no odor escapes after the housing cover 102 seals the inlet, thus improving the user experience.

[0035] It is understandable that the specific structure of the trash can 103 can be a specific design or a structure of an existing product. Furthermore, to meet users' needs for different sized trash bags, the trash can 103 can be replaced with different sizes or suitable models for users to choose from. For example, the trash can 103 can be a hollow structure along the first direction, containing several independent trash bags connected sequentially between adjacent bags; alternatively, it can be a single, continuous hollow trash bag. Each time the trash bag is pulled down, the user can manually tie a knot at the bottom of the bag, or a sealing device can be provided at the bottom of the casing 101, allowing the trash to pass through the trash can 103 and enter the trash bag for collection when the user disposes of the trash.

[0036] The closing component 20 is located at the outlet, preferably below the trash can near the outlet. The closing component 201 is connected to the housing body 101. When the user takes out the trash bag full of trash, the trash bag in the trash can 103 needs to be pulled down again. At the same time, the closing component 201 is opened by the switch component 202 so that the trash bag can pass through the closing component 201. Finally, the switch component 202 is released, and the closing component 201 clamps the trash bag, effectively reducing the leakage of odor from the trash bag.

[0037] In the above implementation process, the channel of the housing body 101 is provided with a garbage box 103, the housing cover 102 is located on the inlet side of the housing body 101, and the closing component 20 is located on the outlet side of the housing body 101. When garbage needs to be disposed of, the housing cover 102 is opened first, and the garbage falls to the closing component 201 after passing through the garbage box 103. At this time, the closing component 201 is in a closed state. Then, the inlet is closed by the housing cover 102, and the closing component 201 is opened by the switch component 202. After the garbage falls into the garbage bag, the closing component 201 clamps the garbage bag. That is, the whole process of the garbage disposed of by the user falling from the closing component 201 to the garbage bag below does not need to be carried out with the housing cover 102 open. The fermentation odor that is isolated and stored in the garbage bag below is effectively isolated, effectively reducing the odor from the garbage bag and achieving odor isolation.

[0038] like Figure 5 As shown, the closing component 201 includes a first closing door 2011 and a second closing door 2012, and the switching component 202 includes a first switch 2021 and a second switch 2022. The first switch 2021 is connected to the first closing door 2011, and the second switch 2022 is connected to the second closing door 2012. When the first switch 2021 and the second switch 2022 are close to each other, the first closing door 2011 and the second closing door 2012 are far apart from each other. When the first switch 2021 and the second switch 2022 are far apart from each other, the first closing door 2011 and the second closing door 2012 are close to each other.

[0039] For example, when the closing member 201 is in the closed state, the first closing door 2011 and the second closing door 2012 are in a close-fitting state. Meanwhile, to ensure even force application to the switch member 202 during the opening of the closing member 201 and improve the user experience, the side of the first switch 2021 opposite to the first closing door 2011 and the side of the second switch 2022 opposite to the second closing door 2012 both extend to the outside of the housing body 101. The first closing door 2011 and the second closing door... 2012 is configured as a symmetrical structure. The first switch 2021 includes, but is not limited to, a door handle, and the second switch 2022 includes, but is not limited to, a door handle. The first switch 2021 is limitedly connected to the first closing door 2011, and the second switch 2022 is limitedly connected to the second closing door 2012. The first switch 2021 and the second switch 2022 are arranged in a figure-eight shape so as to drive the movement of the first closing door 2011 and the second closing door 2012 through the first switch 2021 and the second switch 2022.

[0040] Understandably, to achieve automatic closing of the closing component 201 after it is opened, a first spring is provided between the first closing door 2011 and the first switch 2021, and a second spring is provided between the second closing door 2012 and the second switch 2022. When the first closing door 2011 and the second closing door 2012 move away from each other, so that the closing component 201 is in the open state, the first spring and the second spring gradually generate the potential energy required for the closing component 201 to close. This allows the first closing door 2011 and the second closing door 2012 to automatically close after the user releases the first switch 2021 and the second switch 2022, thus clamping the garbage bag. At the same time, the combined action of the first spring and the second spring ensures the clamping tightness of the closing component 201 on the garbage bag, reducing the leakage of odor from the garbage bag. The setting of the elastic element is not limited to the above scheme; similar functional elements in existing designs can also be used to achieve the automatic closing effect of the closing component.

[0041] Reference Figure 6-9To achieve synchronous rotation of the switch 202 and the closing member 201, the connection method can be as follows: the first switch 2021 is equipped with a first polygonal hole 2061, and the first closing member 2011 is equipped with a first extension 2015. The first extension 2015 is configured with a polygonal outer peripheral protrusion that matches the first polygonal hole 2061. The second switch 2022 is equipped with a second polygonal hole 2062, and the second closing member 2012 is equipped with a second extension 2016. The second extension 2016 is configured with a polygonal outer peripheral protrusion that matches the second polygonal hole 2062. After the adaptation, when a person presses and rotates the switch 202, the torque is transmitted to the closing member 201 through the combination of the polygonal hole and the extension, causing the closing member 201 to rotate. Of course, in other embodiments, the first switch 2021 and the first closing member 2011 are integrally formed or fixed with screws, and the second switch 2022 and the second closing member 2012 are integrally formed or fixed with screws.

[0042] In the above process, the first closing door 2011 is controlled by the first switch 2021, and the second closing door 2012 is controlled by the second switch 2022. When it is necessary to put garbage into the garbage bag, it is only necessary to control the first switch 2021 and the second switch 2022 to move closer to each other. After the garbage enters the garbage bag, the first closing door 2011 and the second closing door 2012 can automatically return to their original positions, thus clamping the garbage bag, effectively reducing the odor from the garbage bag and achieving odor isolation.

[0043] Please refer to again Figure 5 The first closing gate 2011 is provided with a first engaging part 2013, and the second closing gate 2012 is provided with a second engaging part 2014. The first engaging part 2013 is configured to engage with the second engaging part 2014.

[0044] For example, the first closing door 2011 and the second closing door 2012 are partially in contact. At the contact position, the first closing door 2011 is provided with a first engaging part 2013 and the second closing door 2012 is provided with a second engaging part 2014. Both the first engaging part 2013 and the second engaging part 2014 are toothed. A first extension body 2015 and a second extension body 2016 are respectively provided above the first engaging part 2013 and the second engaging part 2014. After an external force is applied to the first switch 2021 and the second switch 2022, the closing member 201 can rotate along the distribution direction of the first engaging part 2013 and the second engaging part 2014, and finally realize the opening and closing of the closing member 201.

[0045] More specifically, a first arc shape is provided on one side of the first closing door 2011, and a second arc shape is provided on one side of the second closing door 2012. A first engaging part 2013 is provided on the outer periphery of the first arc shape, and a second engaging part 2014 is provided on the outer periphery of the second arc shape. The length of the first engaging part 2013 and the second engaging part 2014 is not specifically limited.

[0046] In the above process, the first closing door 2011 and the second closing door 2012 mesh with each other, which can ensure that after the user operates the first switch 2021 and the second switch 2022, the first closing door 2011 and the second closing door 2012 rotate synchronously, while effectively improving the stability of the structure and the clamping degree of the garbage bag when the closing component 20 is closed.

[0047] In one embodiment, one end of the closing member 201 is attached to the housing body 101, and the other end extends along the direction away from the housing body 101 and approaches the central axis of the closing member 201. For example, the closing member 201 is set in a conical shape, and the upper end of the closing member 201 is larger than the lower end. This not only helps to clamp the garbage bag, but also facilitates the garbage to fall into the garbage bag after the user disposes of the garbage, reducing the degree of contamination of the closing member 201 by the garbage and reducing the leakage of odors.

[0048] Reference Figure 6-8 To improve the sealing effect and maintain it for a longer period, the present invention has specially designed the joint between the first sealing door 2011 and the second sealing door 2012. As mentioned above, the sealing member 201 is generally conical in shape with a V-shaped cross-section. The sealing at the joint edge of the first sealing door 2011 and the second sealing door 2012 is crucial to the overall leak-proof effect. If fine debris remains during use or the elastic clamping force decreases after long-term use, odor leakage will occur at the joint edge.

[0049] The present invention provides an L-shaped first lower extension edge 2017 at the mating edge of the first closing door 2011 and an approximately U-shaped second lower extension edge 2018 at the mating edge of the second closing door 2012. The bottom end of the first lower extension edge 2017 is higher than the bottom end of the second lower extension edge 2018. When no pressure is applied to the switch 202 by hand (the switch is in the open state), the closing door is in the closed state. At this time, the first lower extension edge 2017 and the second lower extension edge 2018 are mated. During the mating process, since the bottom end of the first lower extension edge 2017 is higher than the bottom end of the second lower extension edge 2018, the bottom end of the first lower extension edge 2017 extends into the U-shaped groove of the second lower extension edge 2018.

[0050] To further illustrate the advantages of this invention, after garbage is disposed of, it remains above the closing component 201. When the switch 202 is pressed, large pieces of garbage fall into the garbage bag below due to gravity. However, some smaller pieces of garbage, especially damp garbage such as a mixture of cat litter and cat excrement, will stick to the garbage bag and cannot be completely removed. In this case, the joint of the closing door can easily be blocked by these cat litter particles, preventing a complete seal. In addition, when the closing component 201 is tightened, the garbage bag inside is not a regular shape, often exhibiting uneven wrinkles. If a smooth closing component joint is used, leakage is likely to occur in the wrinkled areas. (Refer to...) Figure 6 The present invention uses a first lower extension edge 2017 and a second lower extension edge 2018 to interlock and connect. The L-shaped lower end of the first lower extension edge 2017 can extend a certain size into the U-shaped groove of the second lower extension edge 2018. Based on the gravity of the garbage bag below (especially when there is some garbage), the garbage bag itself forms a certain tension at the joint of the closing part. At this time, by extending a certain size from the L-shaped lower end of the first lower extension edge 2017 into the U-shaped groove of the second lower extension edge 2018, the closing of the garbage bag can be pressed to the maximum extent. Even if there are some small particles or wrinkles, they can be clamped to the maximum extent to prevent odor leakage.

[0051] The design of this invention can also prevent insufficient clamping force due to aging to a large extent. Springs or plastic devices themselves will become fatigued due to increased use time, and it is common for them to become unable to clamp after a period of use. This invention sets the L-shaped lower end of the first lower extension edge 2017 to extend a certain size into the U-shaped groove of the second lower extension edge 2018, wherein the extension size can be appropriately enlarged to enhance the resistance to device aging fatigue and maintain a long-lasting anti-leakage effect.

[0052] Reference Figure 9 The first switch 2021 has a first hand operation part 2031 at one end, which is connected to a first swing part 2041. The first swing part 2041 is connected to a first snap-fit ​​part 2051, and a first polygonal hole 2061 is opened in the middle of the first snap-fit ​​part 2051. The second switch 2022 has a second hand operation part 2032 at one end, which is connected to a second swing part 2042. The second swing part 2042 is connected to a second snap-fit ​​part 2052, and a second polygonal hole 2062 is opened in the middle of the second snap-fit ​​part 2052.

[0053] The first and second hand operating parts and the first and second swing parts are approximately perpendicular to the ground (taking the first switch 2021 as an example, this direction is adjacent). Figure 9 The height dimension (in the z-axis direction, i.e., the vertical direction when the housing body 101 is placed on the ground) and the horizontal dimension (see attached) Figure 9 The width dimension (in the y-axis direction) is such that the height dimension is much larger than the width dimension; the first and second snap-fit ​​portions have a dimension approximately perpendicular to the ground direction (see attached...). Figure 9 The height dimension (in the z-axis direction, i.e., the vertical direction when the housing body 101 is placed on the ground) and the horizontal dimension (see attached) Figure 9 The width dimension (in the y-axis direction) is much larger than the height dimension.

[0054] More importantly, the height of the first and second manual operating parts is greater than the height of the first and second swing parts, while the height of the first and second swing parts is slightly smaller than the height of the rectangular window on the front side of the housing body 101. This allows the first and second swing parts of the switch 202 to pass through the rectangular window and slide horizontally within it during manual opening or automatic closing. The larger height of the first and second manual operating parts compared to the first and second swing parts facilitates their placement outside the rectangular window, and the relatively larger size also aids in the execution of manual pressing actions.

[0055] Furthermore, refer to Figure 9 The overall structure of the first switch 2021 and the second switch 2022 is distributed in an approximately straight line along the x-axis (taking the first switch as an example, the description of the second switch is omitted), and the length dimension in the x-axis is significantly greater than the height dimension in the z-axis. Combined with the fact that the opening angle between the first switch 2021 and the second switch 2022 is the largest when the switch 202 is in the default closed state, the human hand can press the human hand operation part to open it. The human hand can obtain the maximum operating torque, forming a force-saving lever. That is, the human hand can realize the opening action of the switch 202 with very little effort, and the operation can be completed with one hand.

[0056] In some embodiments, the closing member 201 is rotatably connected to the housing body 101. This allows the user to control the closing member 201 via the switch member 202, and the closing member 201 can automatically close after the user releases the switch member 202, thus sealing the garbage bag.

[0057] For example, the housing body 101 is provided with two protrusions along the first direction. One of the protrusions extends to the connection position between the first closing door 2011 and the first switch 2021, and its lower end is fixed with a screw cap. The other protrusion extends to the connection position between the second closing door 2012 and the second switch 2022, and its lower end is fixed with a screw cap.

[0058] During the design process, the inventors discovered that existing products, when removing garbage bags and cutting them, generally either have a costly and prone to malfunctioning thermal cutting device, or the cutting device is located inside the flip door, which is inconvenient for cutting garbage bags. Users usually need to use one hand to stabilize the garbage can itself and the other hand to cut it, in order to ensure that the garbage can does not tip over or fall over during the cutting process.

[0059] Therefore, the trash can provided in this application also includes a cutting component 30. The cutting component 30 is connected to the side of the housing body 101 near the switch member 202 and is used to cut the trash bag. For example, the cutting component 30 is disposed on the housing body 101 so that the cutting position faces the operator. During the cutting process, the entire device is more stable under force, less prone to tipping or overturning, and easier to cut along the path direction, making the use process more reasonable and user-friendly.

[0060] In the above implementation process, the cutting component 30 and the switch component 202 are located on the same side of the housing body 101. This not only allows for cutting garbage bags without excessively stretching them, thus preventing the garbage can from tipping over or falling over when cutting the garbage bag, but also makes the operation more convenient and user-friendly.

[0061] like Figure 2 As shown, the housing cover 102 includes a first cover 1021 and a second cover 1022. The first cover 1021 is fitted onto the housing body 101, and the second cover 1022 is located on the side of the first cover 1021 away from the housing body 101.

[0062] For example, the first cover 1021 is located below the second cover 1022, and both the first cover 1021 and the second cover 1022 can be rotatably connected to the housing body 101 via a connecting shaft.

[0063] In order to guide the disposal of garbage, the first cover 1021 is designed as a hollow structure. The first cover 1021 is connected to the garbage box 103. The outer side of the first cover 1021 is connected to the main body of the shell 101, and its inner side extends downward along the direction close to the main body of the shell 101 to form a cone with an opening. At the same time, in order to ensure that there is no odor leakage around the periphery of the first cover 1021 and the main body of the shell 101, the upper end of the first cover 1021 and the main body of the shell 101 is designed to be sealed. For example, the first cover 1021 can be fastened to the main body of the shell 101. Of course, it is also possible to add a sealing element between the first cover 1021 and the main body of the shell 101.

[0064] It should be noted that the bottom opening size of the first cover 1021 is not larger than the opening size of the garbage box 103, ensuring that garbage can be smoothly put into the garbage bag. When the first cover 1021 covers the main body 101 of the housing, it can be used to fix the garbage box 103. When the first cover 1021 is opened relative to the main body 101 of the housing, it can be used to replace the garbage box 103.

[0065] The second cover 1022 can be rotatably connected to the main body 101 of the housing. After the garbage is disposed of, the second cover 1022 rotates relative to the main body 101 of the housing, and finally the lower end face of the second cover 1022 fits against the first cover 1021, thus achieving a secondary seal against the odor inside the garbage bag.

[0066] In the above implementation process, the first cover 1021 is connected to the housing body 101. When the user disposes of garbage, it can guide the garbage into the inner cavity of the garbage box 103 and also serve to fix the position of the garbage box. The second cover 1022 can be rotatably connected to the housing body 101 and can be used to cover the side of the housing assembly 10 near the inlet. Several cover structure connections in this invention are sealed to effectively reduce gas leakage when garbage is disposed of.

[0067] like Figures 1-2 As shown, the housing assembly 10 also includes a receiving housing 104, which is connected to the side of the housing body 101 near the outlet, and the receiving housing 104 is provided with a storage space configured to accommodate a portion of the structure of a garbage bag passing through the closing member 201.

[0068] For example, the housing 104 is located below the housing body 101. The housing 104 and the housing body 101 can be detached and connected by a snap fastener. The storage space of the housing 104 has a certain depth, which allows the garbage bag to pass through the closing assembly 20 and be collected in the storage space.

[0069] In some embodiments, the housing assembly 10 further includes a cover door 105 connected to the receiving housing 104 for removing the garbage bag. It is understood that a dispensing outlet is provided on one side of the receiving housing 104, and the dispensing outlet, the switch 202, and the cutting assembly 30 can be located on the same side of the garbage bin for user convenience. The cover door 105 is used to cover or open the dispensing outlet. When the cover door 105 is open relative to the receiving housing 104, the user can remove the garbage bag from the storage space. When the cover door 105 covers the receiving housing 104, a sealed state can be maintained between the cover door 105 and the receiving housing 104.

[0070] The process of removing the garbage bag: When the garbage bag is full (the user can observe by opening the cover door 105, or by opening a transparent observation port on the housing 104, or by setting a detection sensor to provide a warning), the user opens the cover door 105. At this time, the closing assembly 20 is still in a sealed state, and there will be no odor leakage. The user holds the garbage bag tightly from below the closing assembly 20 with one hand and performs a sealing operation. The other hand can control the switch 202 to release it, so that the user can pull out the garbage bag in a sealed state.

[0071] After being pulled out to a certain length, the user can use one hand to directly cut the tightened garbage bag opening on the cutting component 30, which faces the user (and is located in the middle of the garbage can for more balanced force), without having to pull the garbage bag to the traditional side door for cutting, thus reducing the risk of tipping over. The cutting component 30 is installed and fixed on the housing body 101, but extends out of the lower outlet of the housing body 101 and finally extends into the receiving housing 104. After the user opens the cover door 105, the cutting component 30 can be fully observed, and the cutting can be completed.

[0072] In some embodiments, the housing assembly 10 further includes a support base 106, which is connected to the side of the housing 104 opposite to the housing body 101. For example, the lower part of the housing 104 is connected to the support base 106. The support base 106 is used to contact the ground for support, and the housing 104 can also be integrally manufactured with the support base 106. It is understood that, in order to achieve automatic garbage bag laying, a vacuum device is provided on the support base 106. When the vacuum device is working, it can create negative pressure on the periphery of the storage space.

[0073] The usage process of this product is described as follows: Before use, the garbage bag 103 needs to be inserted. When using it for the first time, the garbage bag inside the garbage bag 103 needs to be pulled out to a sufficient length, and then the end (or bottom) of the garbage bag needs to be tied to form a garbage bag that is open at one end and closed at the other. Open the second cover 1022 and the first cover 1021, and then the garbage bag can be inserted into the garbage bag 103. Squeeze the switch 202, at which point the closing piece 201 will open. Place the sufficiently long garbage bag under the closing piece 201, release the switch 202, and the closing piece 201 will close. Close the first cover 1021 and the second cover 1022 to complete the insertion.

[0074] When it is time to empty the waste, open the second cover 1022 and the waste can be poured in. At this time, the waste passes through the interior of the waste box 103 (hollow structure) and is located above the closing piece 201. The hollow part of the waste box 103 is located in the area between the first cover 1021 and the closing piece 201.

[0075] When the switch 202 is squeezed with one hand, the closing part 201, through the action of the first engaging part 2013 and the second engaging part 2014, simultaneously opens its first closing door 2011 and second closing door 2012 from the center to both sides. At the same time, the garbage falls into the garbage bag under the influence of gravity. When the switch 202 is released, the closing part 201 closes. It can be seen that when the garbage can is in use, the closing part 201 forms a first space for receiving garbage between its upper part and the outer shell lid, which is used to hold the garbage; the closing part 201 forms a second space for receiving garbage between its lower part and the outer shell, which receives the garbage that falls from the first space after the user opens the closing part 201.

[0076] After emptying the waste, close the second cover 1022.

[0077] If the trash bag needs to be replaced after multiple uses, first open the cover door 105 and remove the trash bag from the storage space. Then, cut the trash bag, with the cutting component 30 facing the user and positioned along the path. Hold the trash can in place with one hand, and with the other hand, hold the trash bag and pass it through the groove of the cutting component 30 to complete the cutting process. Pull the ready-to-use trash bag out of the trash container 103 with a little force, tie a knot at the end, and place it in the trash can. Then, tie the trash bag containing waste and discard it. The entire disposal process is odor-free, providing a very good user experience.
