Abstract
Description
Technical Field
[0001] This invention relates to the field of cleaning equipment technology, and more particularly to a vacuum cleaner. Background Technology
[0002] Vacuum cleaners are also known as portable vacuum cleaners, mainly because they are smaller and more convenient to use compared to canister or upright vacuum cleaners. To make vacuum cleaners lighter and more portable, their size is generally kept small. However, as the overall size of the vacuum cleaner decreases, the volume of its dust cup also decreases. When there is a lot of dust to clean, a large amount of dust will accumulate in the dust cup, causing a decrease in suction power and a reduction in cleaning ability. Summary of the Invention
[0003] To address the shortcomings of the aforementioned technologies, this invention provides a vacuum cleaner that, by incorporating two containers, increases the dust storage capacity of the vacuum cleaner while maintaining its cleaning capabilities.

In the first state, the suction airflow generated by the suction motor does not pass through the first container or only a small portion of the suction airflow flows through the first container. In the second state, all or at least half of the suction airflow generated by the suction motor flows through the first container to transfer at least a portion of the dirt in the dust cup assembly into the first container.
[0005] Optionally, the fluid channel includes: The first fluid channel is in fluid communication with the dust cup outlet of the dust cup assembly and the motor inlet of the suction motor. The second fluid channel is fluidly connected to the dust cup discharge port of the dust cup assembly and the motor air inlet of the suction motor, and the internal space of the first container forms part of the second fluid channel.
[0006] On the other hand, the present invention also provides a vacuum cleaner, including A housing that defines an accommodating space, within which a suction motor is disposed, the suction motor being used to generate a suction airflow; A dust cup assembly is disposed in the housing, and the dust cup assembly is used to separate the suction airflow carrying dirt and store the separated dirt; A first container is disposed in the housing, the first container being used to receive at least a portion of the dirt transferred out from the dust cup assembly; The dust cup assembly includes a dust cup inlet, a dust cup outlet, and a dust cup discharge port. The dust cup discharge port is configured to be in fluid communication with the motor inlet of the suction motor. When the dust cup discharge port is in fluid communication with the motor inlet of the suction motor, the suction airflow can transfer at least a portion of the dirt in the dust cup assembly to the interior of the first container through the dust cup discharge port.
[0007] Optionally, the vacuum cleaner includes a fluid channel, wherein the fluid channel includes: The first fluid channel is in fluid communication with the dust cup outlet of the dust cup assembly and the motor inlet of the suction motor. The second fluid channel is fluidly connected to the dust cup discharge port of the dust cup assembly and the motor air inlet of the suction motor, and the internal space of the first container forms part of the second fluid channel.
[0008] Optionally, a fluid regulator is configured to adjust the airflow rate in the first fluid channel and the second fluid channel; or The fluid regulator is configured to adjust the airflow rate only in the second fluid channel.
[0009] Optionally, the second fluid channel includes a third fluid channel disposed upstream of the first container and a fourth fluid channel disposed downstream of the first container; The third fluid channel connects the dust cup discharge port of the dust cup assembly and the first air inlet of the first container; The fourth fluid channel connects the first air outlet of the first container and the motor air inlet of the suction motor.
[0010] Optionally, the fluid regulator is disposed in the third fluid channel and configured to regulate the airflow rate of the third fluid channel.
[0011] Optionally, the fluid regulator includes a three-way pipe and a regulating element, the three-way pipe including a first pipe, a second pipe and a third pipe; the first pipe is part of the first fluid channel, and the second pipe is part of the fourth fluid channel.
[0012] Optionally, the suction motor is at least partially disposed in the third pipeline.
[0013] Optionally, the adjusting element is used to adjust the airflow between the first pipeline and the second pipeline.
[0014] Optionally, the dust cup assembly further includes a dust outlet, which is configured to clean dirt from inside the dust cup assembly after the dust cup assembly is separated from the housing.
[0015] Optionally, the dust cup assembly defines a cyclone chamber and a dust collection chamber disposed outside the cyclone chamber; the dust cup inlet of the dust cup assembly is in fluid communication with the cyclone chamber, and the dust cup outlet of the dust cup assembly is in fluid communication with the dust collection chamber.
[0016] Optionally, the fluid regulator is configured to close and open the dust cup discharge port of the dust cup assembly, such that the dust cup assembly cannot be removed from the housing when the dust cup discharge port is open.
[0017] This invention provides a vacuum cleaner comprising a housing, a dust cup assembly disposed within the housing, and a first container. The housing defines a receiving space, within which a suction motor is disposed, generating a suction airflow. The dust cup assembly, disposed within the housing, separates and stores the separated dirt carried by the suction airflow. The first container, disposed within the housing, receives at least a portion of the dirt transferred from the dust cup assembly. The dust cup assembly includes a dust cup inlet, a dust cup outlet, and a dust cup discharge port, the dust cup discharge port being configured to be in fluid communication with the motor inlet of the suction motor. When the dust cup discharge port is in fluid communication with the motor inlet of the suction motor, the suction airflow can transfer at least a portion of the dirt within the dust cup assembly through the dust cup discharge port to the interior of the first container. Using this structure, the vacuum cleaner has two containers (dust cup assembly and first container), and with the control of the fluid channel, it eliminates the need to place the vacuum cleaner at a base station for dirt collection. During use, this increases the overall dirt collection capacity of the vacuum cleaner while maintaining its suction power. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0020] It should be noted that if the embodiments of the present invention involve directional indication, the directional indication is only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indication will also change accordingly.
[0021] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances. This application discloses a vacuum cleaner, which can be one of the following: a handheld vacuum cleaner 100, an upright vacuum cleaner, a canister vacuum cleaner, or a robotic vacuum cleaner. (Reference) Figure 1 , Figure 1 A handheld vacuum cleaner 100 (mite remover) is disclosed. The handheld vacuum cleaner 100 generally includes a housing 1, which may include a handle for the user to operate. The housing 1 is generally assembled from multiple injection-molded parts, which will not be detailed here. The housing 1 defines a receiving space within which a suction motor 2 is disposed, generating a suction airflow. The vacuum cleaner also includes a dust cup assembly 3, which separates and stores the dirt-laden airflow entering from the suction port 11. The dust cup assembly 3 is generally disposed within the housing 1, which generally defines a receiving space for mounting the dust cup assembly 3. The dust cup assembly 3 separates and stores the dirt-laden suction airflow.
[0023] refer to Figure 1-4When the dust cup assembly 3 accumulates a certain amount of dirt, the dirt may affect the airflow, or some dirt may adhere to the filter screen, potentially affecting the vacuum cleaner's suction power. To avoid affecting the vacuum cleaner's suction power, the vacuum cleaner also includes a first container 4 disposed in the housing 1. The first container 4 is disposed in the housing 1 and is used to receive at least a portion of the dirt transferred from the dust cup assembly 3. To achieve dirt transfer, a fluid channel 5 is defined within the vacuum cleaner. The fluid channel 5 includes a first state and a second state. In the first state, the suction airflow generated by the suction motor 2 does not pass through the first container 4 (see reference). Figure 5 Or only a small portion of the suction airflow flows through the first container 4 (reference). Figure 6 This small portion of the suction airflow can be defined as the first suction airflow. In the second state, the total suction airflow generated by the suction motor 2 (see reference) Figure 7 Or at least half of the suction airflow flows through the first container 4 (reference). Figure 8 The first suction airflow is used to transfer at least a portion of the dirt within the dust cup assembly 3 into the first container 4. More than half of the airflow can be defined as the second suction airflow. The flow rate of the first suction airflow is less than the flow rate of the second suction airflow. Preferably, the flow rate of the second suction airflow is three times or more greater than the flow rate of the first suction airflow. The first container 4 is preferably a dust bag; however, it can also be other reusable containers, which will not be detailed here.
[0024] The dust cup assembly 3 includes a dust cup inlet 31, a dust cup outlet 32, and a dust cup ash discharge port 33. The dust cup ash discharge port 33 is configured to be in fluid communication with the motor inlet 21 of the suction motor 2. The dust cup assembly 3 may also include an ash emptying port 34, which is configured to clean the dirt inside the dust cup assembly 3 after it is separated from the housing 1. Users can clean the interior of the dust cup assembly 3 through the ash emptying port 34. To improve separation efficiency, the dust cup assembly 3 may include a cyclone chamber 35 and a dust collection chamber 36. The cyclone chamber 35 and the dust collection chamber 36 may be located within the same chamber. The dust collection chamber 36 may also be located outside the cyclone chamber 35. When the dust collection chamber 36 and the cyclone chamber 35 are separated, the dust cup inlet 31 is in fluid communication with the cyclone chamber 35, and the dust cup outlet 32 is in fluid communication with the dust collection chamber 36. Alternatively, the dust cup assembly 3 may only have a filter screen and may not include a cyclone separator.
[0025] When the dust cup discharge port 33 is in fluid communication with the motor air inlet 21, the suction airflow can transfer at least part of the dirt in the dust cup assembly 3 to the inside of the first container 4 through the dust cup discharge port 33. During the operation of the vacuum cleaner, as dirt gradually accumulates in the dust cup assembly 3, it will slowly begin to affect the suction power of the vacuum cleaner. At this time, the user can switch the fluid channel 5 from the first state to the second state through the fluid regulator 6. At this time, a large amount of suction airflow flows through the first container 4, which can transfer the dirt in the dust cup assembly 3 to the first container 4. After the dirt transfer is completed, switch back to the first state. At this time, the dust cup assembly 3 is basically empty, and the suction power of the vacuum cleaner can still be maintained at the optimal state. The fluid regulator 6 can be any form of valve structure or airflow regulation structure, which will not be described in detail here. By setting two containers (dust cup assembly 3 and first container 4) in the vacuum cleaner, and with the control of the fluid channel 5, it is not necessary to put the vacuum cleaner at the base station for dirt collection. The vacuum cleaner disclosed in this application can increase the overall dirt collection capacity of the vacuum cleaner while ensuring that the suction power of the vacuum cleaner does not decrease during use.
[0026] refer to Figure 1-4 Specifically, the fluid channel 5 includes a first fluid channel 51 and a second fluid channel 52. The first fluid channel 51 is fluidly connected to the dust cup outlet 32 of the dust cup assembly 3 and the motor inlet 21 of the suction motor 2. The second fluid channel 52 is fluidly connected to the dust cup discharge outlet 33 of the dust cup assembly 3 and the motor inlet 21 of the suction motor 2.
[0027] refer to Figure 5-8 Based on the above structure, one implementation method is as follows: The fluid regulator 6 is configured to adjust the airflow of the first fluid channel 51 and the second fluid channel 52. In this embodiment, the fluid regulator 6 can be located near the dust cup outlet 32 and the dust cup discharge port 33. When the fluid channel 5 is in the first state, the dust cup outlet 32 is open, and the dust cup discharge port 33 is closed or only partially open. At this time, most of the suction airflow will not flow through the first container 4. After a period of use, when it is necessary to transfer the dirt in the dust cup assembly 3 to the first container 4, the user can use the fluid regulator 6 to put the fluid channel 5 in the second state. At this time, the dust cup discharge port 33 is opened (while the dust cup outlet 32 is closed or the flow rate of the dust cup outlet 32 is reduced), and at least a portion of the suction airflow will transfer the dirt in the dust cup assembly 3 to the first container 4. After the dirt in the first container 4 has been transferred, the user can use the fluid regulator 6 to adjust the fluid channel 5 back to the first state. At this time, the dirt in the dust cup assembly 3 has been basically emptied and will not significantly affect the suction power of the vacuum cleaner. Of course, the fluid regulator 6 can also be set in other locations to adjust the first fluid channel 51 and the second fluid channel 52, for example, at the motor inlet 21 of the suction motor 2.
[0028] refer to Figure 5 , 6 8. Based on the above structure, one implementation method is as follows: The fluid regulator 6 is configured to adjust only the airflow through the second fluid channel 52. The fluid regulator 6 can be installed at the dust cup discharge port 33, or placed anywhere within the first air inlet 41 of the first container 4 or the second fluid channel 52. By adjusting the airflow through the second fluid channel 52, most of the airflow can pass through the second fluid channel 52, transferring dust from the dust collection chamber 36 to the first container 4. Once the dirt in the dust collection chamber 36 has been transferred, the fluid regulator 6 can reduce or cut off the airflow through the second fluid channel 52 to ensure the vacuum cleaner's suction power.
[0029] refer to Figure 9-18 Based on the above structure, one implementation method is as follows: The second fluid channel 52 includes a third fluid channel 53 disposed upstream of the first container 4 and a fourth fluid channel 54 disposed downstream of the first container 4. The third fluid channel 53 connects the dust cup discharge port 33 of the dust cup assembly 3 and the first air inlet 41 of the first container 4. The fourth fluid channel 54 connects the first air outlet 42 of the first container 4 and the motor air inlet 21 of the suction motor 2. The fluid regulator 6 is configured to regulate the airflow of the third fluid channel 53. Alternatively, the fluid regulator 6 regulates the airflow of the fourth fluid channel 54.
[0030] refer to Figure 11-18The fluid regulator 6 includes a three-way pipe 61 and an adjusting element 62. The three-way pipe 61 includes a first pipe 63, a second pipe 64 and a third pipe 65. The first pipe 63 is part of the first fluid channel 51 and the second pipe 64 is part of the fourth fluid channel 54.
[0031] To save space and ensure the airtightness of the pipeline, the suction motor 2 is at least partially installed in the third pipeline 65.
[0032] Continue to refer to Figure 11-18 The regulating component 62 is used to regulate the airflow between the first pipe 63 and the second pipe 64. The regulating component 62 can be manually operated, including a baffle and a handle connected to the baffle. The user can adjust the position of the baffle by adjusting the handle to regulate the airflow between the first pipe 63 and the second pipe 64. The baffle can also directly close one of the first pipes 63 and open the other. The regulating component 62 can also be electrically operated, automatically adjusting based on a signal output by the user.
[0033] Furthermore, based on any of the above embodiments, the vacuum cleaner also includes a sensor for detecting the volume of dirt in the dust cup assembly 3. The sensor type is a common structure in the prior art and will not be described in detail here. The adjusting member 62 is signal-connected to the sensor. When the sensor detects that the volume of dirt has reached a certain level, the adjusting member 62 receives the signal from the sensor and automatically adjusts the fluid channel 5 to transfer at least a portion of the dirt in the dust cup assembly 3 to the first container 4. After the dirt in the dust cup assembly 3 has been transferred, the adjusting member 62 adjusts the fluid channel 5.
[0034] Furthermore, based on any of the above embodiments, when the fluid regulator 6 is positioned near the dust cup discharge port 33 of the dust cup assembly 3 to adjust the opening area of the dust cup discharge port 33, in order to prevent dirt from the removed dust assembly from flowing out of the dust cup discharge port 33, the fluid regulator 6 is also configured to be able to close and open the dust cup discharge port 33 of the dust cup assembly 3. When the dust cup discharge port 33 is in the open state, the dust cup assembly 3 cannot be removed from the housing 1. Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
