Description

Technical Field

[0001] This utility model relates to the field of vacuum sealing device technology, and more specifically, to a handheld vacuum sealing machine. Background Technology

[0002] With the continuous development of food preservation technology, vacuum preservation has become one of the important means of extending the shelf life of food in daily life. Vacuum bags, vacuum cans, and other containers effectively reduce the oxygen content inside the container by creating a vacuum, thereby inhibiting bacterial growth and achieving a preservation effect. Currently, the most commonly used household vacuum sealing equipment is the handheld vacuum sealer, which works by using a built-in vacuum pump to extract air from the container to create a negative pressure environment. Traditional handheld vacuum sealers often have many inconveniences during use, such as the inability to collect water, causing water vapor generated during vacuuming to drip onto the ground; and the inability to store the charging cable, affecting the storage of the handheld vacuum sealer. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a handheld vacuum sealing machine that can improve ease of use.

[0005] In an optional embodiment, the vacuum assembly includes a water-air pump.

[0006] In an optional embodiment, the handheld vacuum sealer further includes a sealing element attached to the outer surface of the housing.

[0007] In an optional embodiment, there is a gap between the sealing member and the outer surface of the housing, and the sealing member has a plurality of protrusions on the side facing the gap.

[0008] In an optional embodiment, a top cover is also included, which covers the end of the second receiving cavity away from the first receiving cavity and is detachably connected to the housing.

[0009] In an optional embodiment, a bottom cover is also included, which covers the end of the first receiving cavity away from the second receiving cavity. The bottom cover is provided with a first gas-liquid inlet, which is connected to the input end of the water-gas dual-purpose pump.

[0010] In an optional embodiment, the handheld vacuum sealing machine further includes a negative pressure sensor and a vent pipe. The bottom cover is also provided with an air inlet. One end of the vent pipe is connected to the air inlet, and the negative pressure sensor is located at the end of the vent pipe away from the air inlet.

[0011] In an optional embodiment, a first sealing element is also included, wherein the vacuuming assembly and the bottom cover are sealed together by the first sealing element, the vacuuming assembly and the liquid collection box are sealed together by the first sealing element, and the vent pipe and the bottom cover are sealed together by the first sealing element.

[0012] In an optional embodiment, the handheld vacuum sealer further includes a suction head, which is sealed to the bottom cover. The suction head is provided with a suction port, which communicates with the first gas-liquid inlet and the air inlet.

[0013] In an optional embodiment, a battery is also included, the first receiving cavity is provided with a charging port, the charging port is connected to the second receiving cavity, and the charging cable is electrically connected to the battery through the charging port.

[0014] The handheld vacuum sealing machine of this application has the following advantages: In the handheld vacuum sealer of this application, the vacuuming component is used to evacuate the container to be vacuumed.

[0023] Reference Figure 1 as well as Figure 2As shown, the handheld vacuum sealing machine involved in the embodiments of this application includes: a housing assembly 100, a vacuuming assembly 200, and a charging cable 300.

[0024] Specifically, the housing assembly 100 includes a housing 110 and a top cover 120. The housing 110 has a first receiving cavity 111 and a second receiving cavity 112, which are spaced apart. The top cover 120 covers the end of the second receiving cavity 112 away from the first receiving cavity 111 and is detachably connected to the housing 110. The vacuum assembly 200 includes a vacuum pump 210 and a liquid collection box 220. The vacuum pump 210 is disposed in the first receiving cavity 111, and the liquid collection box 220 is connected to the outside of the housing 110 and communicates with the output end of the vacuum pump 210. The vacuum pump 210 is a water-air dual-purpose vacuum pump. The charging cable 300 is housed in the second receiving cavity 112.

[0025] In the handheld vacuum sealing machine of this application, the vacuuming component 210 is used to vacuum the container to be vacuumed. Since the vacuuming component 210 is a dual-purpose vacuuming component for both water and gas, both gas and liquid can be drawn into the vacuuming component 210. Since the output end of the vacuuming component 210 is connected to the liquid collection box 220, both gas and liquid drawn into the vacuuming component 210 can enter the liquid collection box 220, thereby realizing the water collection function of the handheld vacuum sealing machine. Furthermore, since the charging cable 300 is housed within the second receiving cavity 112, and the top cover 120 is fitted onto the end of the second receiving cavity 112 furthest from the first receiving cavity 111 and detachably connected to the housing 110, the charging cable 300 can be housed within the second receiving cavity 112, preventing its loss and facilitating its storage, thus improving the portability of the handheld vacuum sealer of this application. Moreover, the top cover 120 can seal the second receiving cavity 112, ensuring the charging cable 300 is stably placed within it. Simultaneously, the charging cable 300 can be retrieved by removing the top cover 120 from the housing 110. Therefore, the handheld vacuum sealer of this application offers high ease of use.

[0026] When processing ingredients with high moisture content (such as fresh fruits and vegetables, pickled foods, or liquid foods), the vacuum pump of a traditional handheld vacuum sealer is inevitably invaded by moisture or liquid, leading to corrosion and damage to internal components and severely affecting its service life. However, in the handheld vacuum sealer of this application, since the vacuum pump 210 is a dual-purpose vacuum pump for both air and water, it has both air extraction and liquid extraction functions. Therefore, the vacuum pump 210 can withstand a certain amount of liquid entering. Even if a small amount of liquid is sucked into the vacuum pump 210, it will not affect the normal operation of the vacuum pump 210. Thus, the handheld vacuum sealer of this application can reduce the possibility of its internal components being damaged by moisture.

[0027] Continue to refer to Figure 2 as well as Figure 3 As shown, the handheld vacuum sealer also includes a sealing component 400, which is connected to the outside of the housing 110 and is at least partially spaced from the surface of the housing 110 to create a sealing gap 410 between the housing 110 and the sealing component 400.

[0028] In this embodiment, since a sealing gap 410 is provided between the housing 110 and the sealing member 400, after the vacuuming of the container to be vacuumed is completed, the sealed part of the container can be placed into the sealing gap 410, and then the sealing member 400 and the surface of the housing 110 clamp the sealed part of the container, and the sealed part of the container can move between the sealing member 400 and the housing 110, thereby achieving a seal at the sealed part of the container. In this way, the handheld vacuum sealer of this application can integrate the vacuuming function and the sealing function, so that there is no need to find an additional sealing clamp to achieve the sealing of the container, thereby improving the ease of use of the handheld vacuum sealer.

[0029] Reference Figure 3 As shown, the sealing member 400 has a clamping portion 420 and a plurality of sealing portions 430. The clamping portion 420 is spaced apart from the surface of the housing 110 to create a sealing gap 410 between the clamping portion 420 and the sealing member 400. The plurality of sealing portions 430 are spaced apart on the clamping portion 420 and protrude from the clamping portion 420 toward the sealing gap 410.

[0030] In this embodiment, since multiple sealing portions 430 are spaced apart on the clamping portion 420 and protrude from the clamping portion 420 toward the sealing gap 410, when the container's sealing portion moves between the clamping portion 420 and the surface of the shell 110, the sealing strip at the container's sealing portion can be pressed by the multiple sealing portions 430, thereby improving the container's sealing performance.

[0031] Reference Figure 2 as well as Figure 4As shown, the housing assembly 100 also includes a bottom cover 130, which covers the end of the first receiving cavity 111 away from the second receiving cavity 112. The bottom cover 130 is provided with a first gas-liquid inlet 131, which is connected to the input end of the vacuum pump 210.

[0032] In this embodiment, the first receiving cavity 111 can be sealed by the bottom cover 130 to improve the protection of the structure inside the first receiving cavity 111. At the same time, gas and liquid can enter the vacuuming component 210 through the first gas-liquid inlet 131 of the bottom cover 130 to realize the vacuuming function of the container to be vacuumed.

[0033] Reference Figure 4 , Figure 5 as well as Figure 7 As shown, the handheld vacuum sealing machine also includes a control component 500, which is disposed in the first receiving cavity 111. The control component 500 includes a controller, a negative pressure sensor, and a vent pipe 510. The vacuuming component 210 and the negative pressure sensor are electrically connected to the controller. The bottom cover 130 is also provided with an air inlet 132. One end of the vent pipe 510 is connected to the air inlet 132, and the negative pressure sensor is disposed at the end of the vent pipe 510 away from the air inlet 132.

[0034] In this embodiment, since one end of the vent pipe 510 is connected to the air inlet 132, and the negative pressure sensor is located at the end of the vent pipe 510 away from the air inlet 132, the gas in the container to be vacuumed can enter the vent pipe 510. The negative pressure sensor monitors the gas pressure in the vent pipe 510 in real time. When the negative pressure sensor detects that the gas pressure is lower than the preset gas pressure, that is, when the vacuum degree in the container reaches the preset vacuum degree, the negative pressure sensor will send a gas pressure signal to the controller. The controller will then send a stop command to the vacuuming component 210 according to the gas pressure signal, so that the vacuuming component 210 stops vacuuming the container. In this way, the handheld vacuum sealer of this application can realize the self-stop function to accurately control the vacuum degree of vacuuming and improve the preservation effect.

[0035] Reference Figure 2 as well as Figure 3 As shown, the control component 500 also includes a battery 520 and a motherboard 530. The battery 520 is electrically connected to the motherboard 530. The controller and the negative pressure sensor are integrated on the motherboard 530. The first receiving cavity 111 is provided with a charging port 1111. The charging port 1111 is connected to the second receiving cavity 112. The charging cable 300 is electrically connected to the motherboard 530 through the charging port 1111.

[0036] In this embodiment, the motherboard 530 is used to electrically connect the controller and the negative pressure sensor, and the battery 520 is used to power the motherboard 530 to power the controller and the negative pressure sensor integrated on the motherboard 530. Since the first receiving cavity 111 is provided with a charging port 1111, which is connected to the second receiving cavity 112, the charging cable 300 is electrically connected to the motherboard 530 through the charging port 1111. Thus, the charging cable 300 in the second receiving cavity 112 can be directly inserted into the charging port 1111 in the second receiving cavity 112 and electrically connected to the motherboard 530 to facilitate charging of the handheld vacuum sealing machine of this application.

[0037] Specifically, refer to Figure 3 As shown, a charging end 540 is provided inside the charging port 1111. The charging end 540 is electrically connected to the motherboard 530. Thus, when the charging cable 300 is electrically connected to the charging end 540, the charging cable 300 can be electrically connected to the motherboard 530 to charge the battery 520.

[0038] Reference Figure 2 as well as Figure 3 As shown, the housing assembly 100 also includes a bracket 140, which is disposed in the first receiving cavity 111 and fixed between the bottom cover 130 and the cavity wall of the first receiving cavity 111 at the end away from the bottom cover 130. The vacuum pump 210, the battery 520 and the main board 530 are all fixedly connected to the bracket 140.

[0039] In this embodiment, the bracket 140 can be fixed by the bottom cover 130 and the cavity wall of the first receiving cavity 111 away from the bottom cover 130, so as to improve the structural stability of the bracket 140 in the first receiving cavity 111. At the same time, the vacuuming component 210, the battery 520 and the motherboard 530 can all be fixed on the bracket 140, so as to improve the structural stability of the vacuuming component 210, the battery 520 and the motherboard 530, thereby improving the structural stability of the components contained in the first receiving cavity 111.

[0043] In this embodiment, the cover portion 133 of the bottom cover 130 is used to connect with the housing 110 to seal the first receiving cavity 111. The main body portion 213 of the vacuuming component 210 is used to vacuum the container to be vacuumed. Since the first inlet portion 134 of the bottom cover 130 and the second inlet portion 214 of the vacuuming component 210 are respectively inserted into the first connecting through hole 151 from both ends and sealed to the hole wall of the first connecting through hole 151, the first inlet portion 134 and the second inlet portion 214 can be sealed to each other by the first sealing component 150, and the first gas-liquid inlet 131 and the second gas-liquid inlet 211 can be connected at the same time, so that gas and liquid can be sequentially drawn into the vacuuming component 210 through the first gas-liquid inlet 131 and the second gas-liquid inlet 211, thereby improving the vacuuming efficiency of the vacuuming component 210.

The first outlet 223 and the second outlet 215 are respectively inserted into the second connecting through hole 152 from both ends, and are sealed to the hole wall of the second connecting through hole 152.

[0045] In this embodiment, the water collection section 222 of the liquid collection box 220 is used to collect the gas and / or liquid extracted from the container to be vacuumed. Since the first outlet section 223 of the liquid collection box 220 and the second outlet section 215 of the vacuuming component 210 are respectively inserted into the second connecting through hole 152 from both ends and sealed to the hole wall of the second connecting through hole 152, the first outlet section 223 and the second outlet section 215 can be sealed to each other by the second sealing component 700. At the same time, the first gas-liquid outlet 221 and the second gas-liquid outlet 212 are connected, so that the gas and liquid can enter the water collection section 222 in sequence through the second gas-liquid outlet 212 and the first gas-liquid outlet 221, thereby reducing the possibility of water vapor entering the first receiving cavity 111 and reducing the corrosion of the structure contained in the first receiving cavity 111.
