Description

Bag changing machine head, packing bag changing machine head and smart trash can Technical Field

[0001] The present invention relates to the technical field of intelligent trash cans, and more particularly to a bag changing machine head, a packing and bag changing machine head and an intelligent trash can. Background Art

[0002] Smart trash cans are a new generation of trash cans on the market that can accommodate trash, automatically pack and bag, seal, and lay out new bags. They can automatically pack and change bags, eliminating the need for manual handling of the bags. This improves hygiene and overall quality of life. The main components of a smart trash can are: a small lid, a large lid, a packing and sealing assembly, a trash can body, and a fan bag laying assembly. Smart trash cans sold on various online platforms generally share this structure.

[0003] Regarding the structure of the intelligent trash can body, a Chinese utility model patent with authorized patent publication number CN219057360U discloses a body, a suction device, and a trash can. The body includes a bottom and sidewalls. The sidewalls are arranged along the circumference of the bottom and surround the bottom to form a trash placement area. Portions of the sidewalls are recessed toward the trash placement area, forming a mounting slot on the outer side of the sidewalls for mounting the trash can's suction device. The recessed portion of the sidewalls forms the bottom of the mounting slot, along with first and second walls disposed oppositely on either side of the bottom. The bottom also includes a suction port, which connects the mounting slot and the trash placement area.

[0004] As can be seen from the technical content disclosed in the aforementioned prior art, existing smart trash cans primarily utilize negative pressure suction to lay out trash bags. These smart trash cans feature a concave sidewall with a fan installed within it. The disadvantages of this prior art are: first, the negative pressure suction fan must be mounted on the can body, and the space it occupies within the concave sidewall indirectly takes up space within the can body intended for storing trash; second, the negative pressure fan requires high suction power, resulting in a high level of noise when placing trash bags.

[0005] Summary of the Invention

[0006] In response to the technical problems existing in the current smart trash cans with negative pressure suction bag laying raised in the background technology, the present invention designs a smart trash can in which a fan is installed in the machine head and the barrel body is designed as a pure barrel structure. This not only reduces the power requirement of the fan, but also allows the machine head to share multiple trash can barrel bodies with the same diameter in succession.

[0007] The present invention provides the following technical solution 1:

[0008] Bag changing head, including:

[0009] Head frame, small cover and fan;

[0010] The head frame is installed on the barrel body of the intelligent trash can, and the head frame is provided with a garbage inlet for the garbage bag to pass through;

[0011] The small cover is connected to the machine head frame and is used to open and close the garbage inlet;

[0012] The fan is installed inside the head frame or inside the small cover and has an air inlet and an air outlet, the air inlet is connected to the internal space of the smart trash can body, and / or the head frame is provided with an air inlet for inhaling external air, the air inlet is connected to the air inlet, and the air outlet is connected to the space inside the garbage bag.

[0013] Through the above technical solution, the core principle of the technical solution of the present invention is:

[0014] First, based on the principle of negative pressure suction / positive pressure blowing combined with bag laying, the air in the barrel is transferred to the inside of the garbage bag. Therefore, in terms of structure, a small power fan is installed at any part of the barrel cover (head frame) or the barrel cover. The small power fan drives the air transfer to complete the laying of garbage bags.

[0015] Second, or alternatively, only the principle of positive-pressure blowing and bagging can be used. In this case, the fan power requirement will not be reduced, but it is preferred to install the fan inside the lid. The rest of the circuit components of the smart trash can can be moved into the lid, which then transforms the trash can into a single-structured ordinary trash can. The lid and the body can be sold separately, and if one is damaged, they can be replaced separately. Moreover, multiple trash cans in a location can share a single lid, and there is no need for a concave structure, thus expanding the effective volume of the trash can body. Of course, for smart trash cans based on the principle of negative-pressure suction / positive-pressure blowing combined with bagging, it is also preferred to install the fan inside the lid, and the rest of the circuit components of the smart trash can can be moved into the lid.

[0016] The present invention further comprises: a bag changing machine head further comprising: a garbage bag assembly; the machine head frame is provided with a consumable material storage area for storing the garbage bag assembly, and the garbage bag assembly is installed in the consumable material storage area.

[0021] The present invention further comprises: an upper air vent is provided on the surface of the installation area, one end of the upper air vent is connected to the air outlet of the fan, and the air blown out from the other end of the upper air vent is transferred to the interior of the garbage bag through the blocking effect of the lower surface of the small cover.

[0022] In order to achieve the following: the air blown out from the other end of the upper air outlet is transferred to the interior of the garbage bag through the blocking effect of the lower surface of the small cover, there are many ways to achieve this. In the case of not being able to fully list them, the following three types of implementation solutions are listed:

[0053] The present invention will be further described in detail below with reference to the embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0054] The intelligent trash can includes two major parts: a bag-packing and bag-changing machine head and a trash can body. The bag-packing and bag-changing machine head is the design and improvement focus of the present invention. The trash can body is detachably mounted on the trash can body. The trash can body of the present invention is a pure body. A pure body means that the complex fan structure, circuit board structure, inner concave grooves, etc. inside the trash can body in the prior art are removed. It only needs to be a container that can hold garbage. At the same time, the bag-packing and bag-changing machine head and the trash can body are interdependent; without the bag-packing and bag-changing machine head, the trash can body cannot be set as a pure body; and without the trash can body, the bag-packing and bag-changing machine head cannot independently complete the storage and bag-packing of garbage.

[0055] The trash can body has a pure barrel structure and no special functional design. Its shape can be a round trash can body, a square trash can body, a polygonal trash can body, etc., and no further details are given here.

[0056] The internal structure of the bag-packing and bag-changing machine head can be divided into three parts: the bag-packing machine head, the closing mechanism and the sealing mechanism, so that the three parts can respectively realize the bag-changing function, the closing function and the bag-packing and sealing function. From the overall point of view, the bag-packing and bag-changing machine head can form a whole with the closing mechanism and the sealing mechanism to form a bag-packing and bag-changing machine head. However, the bag-packing and bag-changing machine head can also be divided into two major parts: the bag-packing machine head as one part and the closing mechanism and the sealing mechanism as another part. The closing mechanism and the sealing mechanism are generally referred to as the packing device in the prior art. The packing device is arranged at the lower part of the bag-packing machine head and is used to pack the garbage bags newly replaced by the bag-packing machine head.

[0057] The closing mechanism can be set as the existing technical structure of multi-rod closing or flexible workpiece closing in the prior art with Chinese patent numbers: ZL202023156464.1 and ZL201910428536.6. The sealing mechanism can be set as the existing technical structure of melt sealing in the prior art with Chinese patent numbers: ZL202123298259.3 and ZL202022714757.0, and in the prior art, the sealing mechanism can be installed inside or beside the closing mechanism to seal and cut the bag opening of the garbage bag closed by the closing mechanism. The packing device (closing mechanism and sealing mechanism) in the present invention is generally arranged inside the bag changing machine head to pack the newly replaced garbage bags in the bag changing machine head. In other embodiments, the packing device (closing mechanism and sealing mechanism) can also be arranged below the bag changing machine head to form two components in the upper and lower positions with the bag changing machine head.

[0058] As shown in Figures 1-6 , the bag changing machine head of the present invention comprises: a machine head frame 1, a small cover 2, a fan 3, and a matching garbage bag assembly 4 as a consumable material. The machine head frame 1 can be directly mounted on the body of the smart trash can or indirectly mounted on the body of the smart trash can by being placed above the packaging device. The machine head frame 1 has a garbage inlet 1-1 for the garbage bags to pass through and a consumable storage area 1-2 for storing the garbage bag assembly 4. The small cover 2 is connected to the machine head frame 1 and is used to open and close the garbage inlet 1-1. The garbage bag assembly 4 is installed in the consumable storage area 1-2. The fan 3 is installed inside the machine head frame 1 and has an air inlet and an air outlet. The air inlet is connected to the internal space of the smart trash can body, and the air outlet is connected to the space inside the garbage bag. To facilitate the installation of the fan 3 and other electronic circuit components, the machine head frame 1 is provided with an installation area 5, and the fan 3 is arranged inside the installation area 5.

[0059] Among them, when the head frame 1 can be directly installed on the barrel body of the smart trash can, the packing device is installed inside the head frame 1. At this time, it is generally necessary to set a bottom plate 6 at the bottom of the head frame 1. The function of the bottom plate 6 is to install the packing device disclosed in ZL201910428536.6, that is, the bottom plate 6 is connected to the bottom end of the head frame 1. At the same time, the bottom plate 6 is provided with a garbage through-port 6-1 and an air valve 6-2 for the garbage bag to pass through. The garbage through-port 6-1 is used for the garbage bag in the garbage bag assembly 4 to pass through the garbage delivery port 1-1 and the garbage through-port 6-1 and be laid in the barrel body. The air valve 6-2 connects the air inlet of the fan 3 with the internal space of the barrel body of the smart trash can.

[0060] The above is the overall installation structure principle of the bag changing machine head. However, there are many actual structural implementation methods of the bag changing machine head product. The embodiments of the present invention cannot be exhaustive, but as many specific implementation solutions as possible are listed below.

[0061] Regarding the shape design of the head frame 1, its shape design is generally consistent with the shape of the bottom trash can barrel, but the shape is not limited and may be different. As shown in Figure 1, in this embodiment, the head frame 1 is configured as a cylindrical barrel, and the garbage inlet 1-1, garbage bag assembly 4, and garbage passage 6-1 are all configured in a shape consisting of arc edges and straight edges.

[0062] In this embodiment, the small cover 2 is rotatably connected to the upper surface of the mounting area 5, and the rotation structure used is a shaft rotation connection. In other embodiments, the small cover 2 can be connected to other locations such as the outer surface of the mounting area, or the small cover 2 can use other rotation connection structures such as hinges, or even detachable related connection structures.

[0063] The surface of the mounting area 5 is provided with an upper air vent 5-1. In this embodiment, the upper air vent 5-1 is provided on the upper surface of the mounting area 5, and there is only one upper air vent 5-1. One end of the upper air vent 5-1 is connected to the air outlet of the fan 3, and the air blown out from the other end of the upper air vent 5-1 is transferred to the interior of the garbage bag through the interior of the small cover 2. The air blown out from the other end of the upper air vent 5-1 is transferred to the interior of the garbage bag through the blocking effect of the lower surface of the small cover 2.

[0064] In other embodiments, more than one upper air vent 5-1 may be provided, and one end of each of the multiple upper air vents 5-1 is connected to the air outlet of the fan 3. Of course, multiple fans 3 may be provided, each corresponding to the other. However, due to limited space in the installation area 5, generally only one fan 3 is provided. The air blown out of the other end of the upper air vent 5-1 may be connected to the air outlet of the fan 3 at one end. The air blown out of the other end of the upper air vent 5-1 is transferred to the interior of the garbage bag through the interior of the small cover 2. Alternatively, the air blown out of the other end of the upper air vent 5-1 is transferred to the interior of the garbage bag through the blocking effect of the lower surface of the small cover 2.

[0065] Therefore, according to the above structure, the air blown out from the upper air outlet 5-1 is transferred to the inside of the garbage bag, and the small cover 2 plays an indispensable role in this process. The small cover 2 can have multiple implementation schemes according to different principles of air transfer. Four implementation schemes of the small cover 2 are listed below.

[0066] First, as shown in Figures 3 and 7 , the air blown out from the other end of the upper air vent 5-1 is transferred to the interior of the garbage bag through the interior of the small cover 2. In the principle of this air transfer, the small cover 2 includes a first body a2-1 and a first air inlet a2-2 and a first air outlet a2-3 that are opened on the bottom surface of the first body a2-1 and are interconnected; the first air inlet a2-2 is connected to the upper air vent 5-1, and the first air outlet a2-3 is connected to the interior space of the garbage bag. During operation, the air output from the air outlet of the fan 3 is input into the first air inlet a2-2 through the upper air vent 5-1. At this time, the air is transferred through the air channel between the first air inlet a2-2 and the first air outlet a2-3, and finally discharged from the first air outlet a2-3 and transferred to the garbage bag.

[0067] Second, as shown in conjunction with Figures 3 and 8 , the air blown out from the other end of the upper air vent 5-1 is transferred to the interior of the garbage bag via the blocking effect of the lower surface of the small cover 2. In the principle of this air transfer, the small cover 2 includes a second body b2-1 and a second sealing edge b2-2. The second sealing edge b2-2 is disposed at the outer edge of the bottom surface of the second body b2-1. The second sealing edge b2-2 is used to seal the contact position between the small cover 2, the machine head frame 1, and the garbage bag assembly 4 when the small cover 2 is closed. During operation, the air output from the air outlet of the fan 3 is input to the bottom of the small cover 2 via the upper air vent 5-1. At this time, the air is transferred to the interior of the garbage bag via the sealing effect of the second sealing edge b2-2 and the blocking effect of the lower surface of the small cover 2.

[0068] Third, as shown in Figures 3 and 9 , based on the aforementioned principle of air transfer, the second sealing edge b2-2 is used to seal the contact area between the small cover 2, the head frame 1, and the garbage bag assembly 4 when the small cover 2 is closed. However, due to the gap between the head frame 1 and the garbage bag assembly 4, the sealing effect of the second sealing edge b2-2 is poor. Therefore, based on this principle of air transfer, a new small cover 2 structure can be designed.

[0069] The small cover 2 includes a third body c2-1, a third rib c2-2, and a third sealing edge c2-3. The third rib c2-2 is provided on the outer edge of the bottom surface of the third body c2-1. The third sealing edge c2-3 is provided on the bottom surface of the third body c2-1 and forms a third air inlet slot c2-4 and a third air outlet slot c2-5. The third air inlet slot c2-4 communicates with the upwind port 5-1, and the third air outlet slot c2-5 communicates with the interior space of the garbage bag. In terms of shape design, the shape of the third air outlet slot c2-5 is consistent with that of the garbage bag assembly 4, and the third sealing edge c2-3 corresponding to the third air outlet slot c2-5 is sealed to the upper surface of the garbage bag assembly 4 when the small cover 2 is closed; the shape of the third air inlet slot c2-4 is an elongated strip, one end of the third air inlet slot c2-4 is connected to the upwind port 5-1, and the other end of the third air inlet slot c2-4 is connected to the third air outlet slot c2-5. The third sealing edge c2-3 corresponding to the third air inlet slot c2-4 is sealed to the upper surface of the garbage bag assembly 4 and the upper surface of the mounting area 5 when the small cover 2 is closed. Although the gap between the head frame 1 and the garbage bag assembly 4 will still affect the sealing effect of the third sealing edge c2-3 corresponding to the third air inlet slot c2-4, the small width of the third air inlet slot c2-4 can greatly reduce the impact of the poor sealing effect caused by the gap between the head frame 1 and the garbage bag assembly 4.

[0070] Fourth, referring to Figures 2, 3, and 10, based on the aforementioned principle of air transfer, the gap between the head frame 1 and the garbage bag assembly 4 still affects the sealing effect of the third sealing edge c2-3 corresponding to the third air inlet slot c2-4. Although the width of the third air inlet slot c2-4 is small, it still has a certain impact. Therefore, based on this principle of air transfer, a new small cover 2 structure can be further designed.

[0071] The small cover 2 includes a fourth body d2-1, a fourth rib d2-2 and a fourth sealing edge d2-3; the fourth rib d2-2 is arranged on the outer edge of the bottom surface of the fourth body d2-1; the fourth sealing edge d2-3 is arranged on the bottom surface of the fourth body d2-1 and forms a fourth air inlet slot d2-4 and a fourth air outlet slot d2-5; the fourth air inlet slot d2-4 is provided with a fourth horizontal plate d2-6 for sealing the gap between the head frame 1 and the garbage bag assembly 3 and is fixed on the fourth sealing edge d2-3, the inlet of the fourth air inlet slot d2-4 is connected to the upwind port 5-1, and the fourth air outlet slot d2-5 is connected to the internal space of the garbage bag. In terms of shape design, the fourth air outlet slot d2-5 is consistent with the shape of the garbage bag assembly 4, and the fourth sealing edge d2-3 corresponding to the fourth air outlet slot d2-5 is sealed to the upper surface of the garbage bag assembly 4 when the small cover 2 is closed. The fourth air inlet slot d2-4 is in the shape of an elongated strip, one end of which is connected to the upper air port 5-1, and the other end of which is connected to the fourth air outlet slot d2-5. Under the action of the fourth transverse plate d2-6, the fourth sealing edge d2-3 corresponding to the exposed fourth air inlet slot d2-4 is only sealed to the upper surface of the installation area 5 when the small cover 2 is closed. The fourth transverse plate d2-6 is sealed to the upper surface of the garbage bag assembly 4 and the upper surface of the installation area 5 when the small cover 2 is closed. Since the fourth transverse plate d2-6 is a plate surface, it can seal the gap between the garbage bag assembly 4 and the installation area 5. Therefore, the influence of poor sealing effect caused by the gap between the head frame 1 and the garbage bag assembly 4 is completely avoided.

[0072] In this embodiment, as shown in Figure 6, the fan 3 is configured as a centrifugal fan. In other embodiments, the fan 3 can also be configured as an axial flow fan.

[0073] As shown in Figure 11, in another embodiment, bags can be laid out using positive pressure. Based on the aforementioned bag-packing and bag-changing head structure, in this embodiment, air inlets 1-3 for drawing in outside air can be opened on the periphery of the head frame 1, and the valve 6-2 on the head frame 1 can be closed. This is because the air inlet of the fan 3 draws air from the air inlet 1-3 to lay out the bags, without the need to draw air from the interior of the barrel through the valve 6-2. Of course, when the air inlet 1-3 is opened on the periphery of the head frame 1, the head frame 1 can still have a structure with the valve 6-2.

[0074] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
