Description

Technical Field

[0001] This utility model relates to the field of vacuum machine technology, and in particular to a vacuum storage machine. Background Technology

[0002] Vacuum organizers have become a common household storage tool due to their ease of operation and high vacuuming efficiency. They are typically used in conjunction with vacuum storage bags. To use, the vacuum organizer's air inlet is connected to the air nozzle of the vacuum storage bag, and then the motor is started to extract the gas from the bag. The basic working principle is that the built-in motor drives the fan blades to rotate, expelling the gas inside the vacuum organizer through the air outlet. This creates a negative pressure inside the vacuum organizer, drawing the gas out of the storage bag through the air inlet, thus compressing and storing items to save space.

[0003] In the prior art, the air inlet and outlet are far apart. For example, in the vacuum machine for clothing bags disclosed in Chinese Utility Model No. CN219452429U, the air inlet and outlet are located at opposite ends of the outer shell. In this case, the gas flow path is longer, and the gas is more likely to encounter more turns and obstacles during the flow, which affects the pumping efficiency. In order to ensure the pumping efficiency, the power of the motor needs to be increased, which means that it consumes more electricity for the same pumping efficiency, or the pumping efficiency is worse for the same motor power.

[0004] Therefore, how to design a vacuum storage machine that can improve pumping efficiency, reduce energy consumption, and enhance user experience is a technical problem that designers and developers need to solve. Utility Model Content

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] This utility model provides a vacuum cleaner 100 that improves pumping efficiency, reduces energy consumption, and enhances the user experience. Figure 1 and Figure 3 As shown, the vacuum chamber 100 includes a housing 110 and a fan assembly 120.

[0034] The fan assembly 120 includes a fan blade 121 and a motor 122. The fan blade 121 is mounted on the output shaft of the motor 122, and the motor 122 drives the fan blade 121 to rotate and generate airflow.

[0035] like Figure 3 As shown, the housing 110 encloses and forms an airflow cavity 111 and a receiving cavity 112. The fan blade 121 is housed in the airflow cavity 111, and the motor 122 is housed in the receiving cavity 112. In this way, the fan blade 121 can drive the gas flow in the airflow cavity 111, and the airflow does not pass through the receiving cavity 112.

[0036] Specifically, such as Figure 2 , Figure 3 and Figure 6As shown, the airflow chamber 111 has an air inlet 1111 on its bottom wall and an air outlet 1112 on its side wall. The bottom wall of the airflow chamber 111 extends outward around the air outlet 1112 to form a tight-fitting wall 1113, which encloses a connecting groove 1114. The airflow chamber 111 communicates with the connecting groove 1114 through the air outlet 1112. When the motor 122 drives the fan blade 121 to rotate, gas enters the airflow chamber 111 through the air inlet 1111 and is then discharged through the air outlet 1112. The air inlet 1111 and air outlet 1112 are respectively located on the bottom wall and side wall of the airflow chamber 111, making the distance between them relatively short and shortening the gas flow path within the airflow chamber 111.

[0037] Preferably, such as Figure 5 and Figure 6 As shown, since the airflow cavity 111 only needs to accommodate the fan blade 121, the volume of the airflow cavity 111 can be made smaller, thereby further reducing the distance between the air inlet 1111 and the air outlet 1112 and shortening the gas flow path; or the air outlet 1112 can be located at the end of the side wall of the airflow cavity 111 near the bottom wall of the airflow cavity 111, which can also effectively reduce the distance between the air inlet 1111 and the air outlet 1112.

[0038] The working principle of the storage vacuum machine 100 of this utility model will be explained below in conjunction with the above structure. Please refer to the following: Figure 2 , Figure 3 and Figure 6 :

[0039] When the vacuum cleaner 100 is used in conjunction with a vacuum bag (not shown), the user inserts the vacuum bag's suction port into the insertion slot 1114, ensuring a tight seal between the sealing wall 1113 and the suction port. The inside of the vacuum bag is connected to the airflow chamber 111 through the air inlet 1111. Then, the motor 122 is started, causing the fan blades 121 to rotate. Under centrifugal force, the gas inside the airflow chamber 111 is thrown against the side wall of the airflow chamber 111 by the fan blades 121 and discharged through the air outlet 1112. At this time, a negative pressure environment is formed inside the airflow chamber 111, thereby drawing the gas inside the vacuum bag into the airflow chamber 111 through the air inlet 1111.

[0040] The gas drawn into the airflow chamber 111 is also thrown towards the side wall of the airflow chamber 111 by the fan blades 121 under the action of centrifugal force, and discharged through the air outlet 1112, resulting in a negative pressure environment inside the airflow chamber 111, thereby continuously extracting the gas from inside the vacuum bag. Understandably, because the gas inside the vacuum bag is continuously extracted, the air pressure inside the vacuum bag is lower than the external atmospheric pressure. The pressure difference will uniformly compress the items inside the vacuum bag, thereby reducing the volume of the items and making them easier to store.

[0041] Once the desired compression state is achieved, the user can turn off the motor 122 and remove the storage vacuum machine 100 from the vacuum bag.

[0042] Compared with the prior art, the storage vacuum machine 100 of this utility model has the following two beneficial effects:

[0043] On the one hand, by setting the air inlet 1111 and the air outlet 1112 on the bottom wall and side wall of the airflow cavity 111 respectively, the distance between the air inlet 1111 and the air outlet 1112 is closer, which effectively shortens the flow path of the gas in the airflow cavity 111, thereby effectively reducing the resistance encountered by the gas flow in the cavity. The fan assembly 120 can drive the gas flow more easily. In addition, while ensuring the pumping efficiency, a smaller power motor 122 can be selected, which not only reduces the manufacturing cost, but also reduces energy consumption.

[0044] On the other hand, since the airflow cavity 111 only contains the fan blade 121 and no other structures, its volume can be designed to be smaller, and the fan blade 121 can fit more closely to the airflow cavity 111, reducing the gap between them. Understandably, the vacuum pump 100 needs to expel the gas already present in the airflow cavity 111 before it can begin pumping. A smaller volume in the airflow cavity 111 results in less gas inside, reducing the time required for the blower assembly 120 to start and for a negative pressure environment to form inside the airflow cavity 111, thereby increasing the pumping speed of the vacuum pump 100. Simultaneously, because the fan blade 121 fits more closely to the airflow cavity 111, the rotating fan blade 121 promotes better unidirectional gas flow within the cavity. Understandably, when the gap between the fan blade 121 and the airflow cavity 111 is large, the flowing gas is more likely to encounter the wall and generate eddies, thus affecting the flow of the main gas stream. The design of this invention reduces the generation of eddies, improves gas flow efficiency, and reduces wind noise, thereby enhancing the user experience.

[0045] Preferably, such as Figure 2 , Figure 3 and Figure 5 As shown, the vacuum storage machine 100 includes an air nozzle 130, which is detachably mounted on the housing 110. The air nozzle 130 has an abutment wall 131, which, after assembly, is located inside the sealing wall 1113. Thus, when the diameter of the vacuum bag's suction inlet is small, the user can mount the air nozzle 130 on the housing 110 and insert the suction inlet into the air nozzle 130, ensuring a tight fit between the abutment wall 131 and the suction inlet. When the diameter of the vacuum bag's suction inlet is large, the user can remove the air nozzle 130 from the housing 110, allowing the vacuum storage machine 100 to be adapted to suction inlets of different diameters, thus expanding its applicability.

[0046] Specifically, such as Figure 5 As shown, the sealing wall 1113 has an extension portion 1115, and the air nozzle 130 has a snap-fit ​​portion 132 that mates with the extension portion 1115. This facilitates the assembly and disassembly of the air nozzle 130, while also providing a simple structure that is easy to manufacture.

[0047] Furthermore, such as Figure 3 and Figure 4 As shown, the blower assembly 120 includes a control main board 123, which is located within the accommodating cavity 112. The motor 122 is electrically connected to the control main board 123. An operation panel 113 is provided on the outer surface of the housing 110, and the operation panel 113 is electrically connected to the control main board 123. Users can control the opening and closing of the vacuum cleaner 100 by using the operation panel 113 to control the motor 122. Specifically, the operation panel 113 is provided with a button 1132 for controlling the motor 122; this button 1132 can be a mechanical button or a touch button.

[0048] Furthermore, such as Figures 2 to 4 As shown, the control mainboard 123 is equipped with multiple LED beads 1231, the side wall of the accommodating cavity 112 is equipped with multiple through holes 1121, and the operation panel 113 is equipped with multiple light-transmitting elements 1131. The light emitted by the LED beads 1231 passes through the through holes 1121 and the light-transmitting elements 1131 in sequence and shines to the outside. The light-transmitting elements 1131 can prevent moisture, dust, etc. from entering the interior of the accommodating cavity 112, thus protecting the internal structure of the accommodating cavity 112.

[0049] At this time, the user can judge the operating status of the vacuum cleaner 100, such as the remaining power and working mode, based on the light emitted by the LED beads 1231.

[0050] In some embodiments, the vacuum cleaner 100 has multiple operating modes, and the user can determine the operating mode of the vacuum cleaner 100 based on the number of LED beads 1231 that are lit. For example, when the user clicks button 1132, the motor 122 starts, and one LED bead 1231 lights up, indicating that the vacuum cleaner 100 is working; when the user clicks button 1132 again, two LED beads 1231 light up, indicating that the vacuum cleaner 100 is in normal mode; when the user clicks button 1132 a third time, three LED beads 1231 light up, indicating that the vacuum cleaner 100 is in high-power mode; and so on.

[0051] Understandably, the control motherboard 123 and motor 122 will generate a certain amount of heat during operation. Since the control motherboard 123 and motor 122 are located in a nearly sealed cavity, if this heat is not dissipated in time, the temperature inside the accommodating cavity 112 will continue to rise, thereby affecting the service life of the control motherboard 123 and motor 122, and also posing a safety hazard.

[0052] Therefore, the vacuum storage machine 100 of this utility model is provided with heat dissipation structures for the control motherboard 123 and the motor 122 respectively.

[0053] Specifically, such as Figure 4 and Figure 5 As shown, a first heat dissipation hole 1122 is provided on the side wall of the accommodating cavity 112 at the location corresponding to the control motherboard 123, and the first heat dissipation hole 1122 connects the accommodating cavity 112 to the outside; a second heat dissipation hole 1123 is provided on the side wall of the accommodating cavity 112 at the location corresponding to the motor 122, and the second heat dissipation hole 1123 connects the accommodating cavity 112 to the outside. In this way, the heat generated during the operation of the control motherboard 123 and the motor 122 is discharged to the outside through the first heat dissipation hole 1122 and the second heat dissipation hole 1123 respectively, thereby solving the above-mentioned problem.

[0054] In some embodiments, such as Figure 6 As shown, there are multiple air inlets 1111, and these multiple air inlets 1111 are distributed along the same straight-line array; there are also multiple air outlets 1112, and these multiple air outlets 1112 are distributed along the shell 110 in an array. Understandably, compared to a single large hole, designing both the air inlets 1111 and air outlets 1112 as multiple small holes effectively ensures the structural strength of the shell 110, and even if some small holes are blocked, the remaining small holes can still function normally. Furthermore, designing the multiple air inlets 1111 as distributed along the same straight-line array can effectively guide the airflow, avoiding turbulence problems caused by intersecting airflow paths during air extraction.

[0055] Preferably, the vacuum storage unit 100 includes a battery (not shown), which is housed within the receiving cavity 112 and electrically connected to the control mainboard 123. In this way, the battery can provide power to the motor 122 and the LED beads 1231. Even when a power source is inconvenient to connect, the vacuum storage unit 100 can still operate normally, improving the user experience. Figure 2 and Figure 4 As shown, the control motherboard 123 is provided with a charging port 1232, which is installed through the housing 110, so as to facilitate the user to charge the battery.

[0056] In some embodiments, such as Figure 3 and Figure 5As shown, the housing 110 is provided with a partition frame 114 for separating the airflow chamber 111 and the receiving chamber 112. The motor 122 is fixed in the receiving chamber 112 through the partition frame 114, and the output shaft of the motor 122 passes through the partition frame 114. In this way, the partition frame 114 can fix the motor 122, preventing the vibration generated by the fan blade 121 during rotation from causing the motor 122 to shake, thereby preventing abnormal noise and other problems. During the air extraction process, there may be a problem of dampness in the items. At this time, the extracted air is also relatively damp. The partition frame 114 can prevent the extracted damp air from entering the receiving chamber 112, thereby preventing the damp air from contacting the motor 122 and circuit components such as the control board 123, ensuring the safety of the air extraction process, and extending the service life of the vacuum machine 100.

[0057] In summary, the vacuum storage machine 100 of this utility model can improve the pumping efficiency, reduce energy consumption, and enhance the user experience.

[0058] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
