DETAILED DESCRIPTION

[0024] The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0025] like Figure 1 and Figure 2 As shown, the utility model provides a vacuum fresh-keeping machine with a handheld vacuuming component, including a machine body 1 and a machine cover 2. When the machine body 1 and the machine cover 2 are closed together, a sealed cavity is formed, and a vacuuming component connected to the sealed cavity is provided in the machine body 1, and a heating and sealing component is provided. When the fresh-keeping container is a fresh-keeping bag, the bag opening can be placed in the sealed cavity for vacuuming and sealing. It should be noted that the specific structure and working principle of the vacuuming component and the heating and sealing component belong to the prior art, and the staff in this field can refer to the structure and working principle of the existing vacuum fresh-keeping machine for implementation, so it is not repeated here.

[0026] like Figures 1 to 5 As shown, the vacuum fresh-keeping machine also includes a handheld device 3 detachably arranged on the machine body 1, and the handheld device 3 includes a shell 31, an air suction nozzle 32, an air inlet pipe 33 and a connecting pipe 34. An air inlet pipe 33 is arranged in the shell 31, and the air suction nozzle 32 is arranged at the end of the shell 31, which is used to connect the air inlet pipe 33 and the fresh-keeping container. One end of the connecting pipe 34 is connected to the air inlet pipe 33, and the other end is connected to the vacuum pumping component. When it is necessary to vacuumize fresh-keeping containers such as fresh-keeping boxes or fresh-keeping bottles that are not convenient to be placed in the sealed cavity of the machine body 1, the handheld device 3 can be used to vacuumize them, so that the use of the vacuum fresh-keeping machine is more flexible and convenient, and can meet the diversified fresh-keeping container needs in the market. Since the handheld device 3 does not have a vacuum pumping component, but shares a set of vacuum pumping components with the machine body 1, the structure of the handheld device 3 is more compact and lightweight, and the design is more reasonable.

[0027] like Figures 2 to 5 As shown, the suction nozzle 32 is provided with a suction pipe 321 for connecting to the fresh-keeping container, and a storage chamber 322 connected to the suction pipe 321; the air inlet pipe 33 is connected to the storage chamber 322. When vacuuming, the air and part of the liquid in the fresh-keeping container enter the suction nozzle 32 from the suction pipe 321, and the liquid enters the storage chamber 322 and accumulates under the action of the air flow, while the gas is extracted along the air inlet pipe 33 and the connecting pipe 34 under the action of the vacuuming component, thereby achieving gas-liquid separation, so that the liquid in the food is stored in the storage chamber 322, avoiding entering the body 1 to damage the internal circuit. When it is necessary to clean the accumulated liquid, it is only necessary to remove the suction nozzle 32 from the handheld device 3 for processing, which is simple and convenient to operate.

[0028] like Figures 2 to 5 As shown, a blocking mechanism that can automatically block or open the air inlet pipe 33 is provided in the housing 31. Specifically, the blocking mechanism includes a float 35, a guide assembly 36 and a plug 37. The float 35 can be raised and lowered in the housing 31 through the guide assembly 36, and is used to drive the plug 37 to block or open the air inlet pipe 33 according to the liquid level in the storage chamber 322. The float 35 can automatically detect the liquid level in the storage chamber 322. When the liquid stored in the storage chamber 322 is large, the float 35 will drive the plug 37 to rise under the action of buoyancy, thereby blocking the air inlet pipe 33. At this time, even if the vacuum assembly is turned on, normal vacuuming cannot be performed. Therefore, the user can be reminded in time to clean the liquid accumulated in the suction nozzle 32 in time, thereby improving the safety performance of the vacuum fresh-keeping machine and effectively extending its service life.

[0029] like Figures 2 to 5 As shown, more specifically, the guide assembly 36 includes a sleeve 361 and a stopper 362. The sleeve 361 is fixed in the housing 31, and guide grooves 363 are provided on both sides of the sleeve 361. The buoy 35 is installed in the sleeve 361, and stoppers 362 are provided on both sides of the buoy 35 after passing through the guide grooves 363. The setting of the guide assembly 36 can ensure that the buoy 35 rises and falls along the set movement path, thereby accurately driving the plug 37 to open or block the air inlet pipe 33.

[0030] like Figures 2 to 5As shown, as a specific installation structure: the housing 31 includes an upper housing 311 and a lower housing 312 which are detachably connected, the lower housing 312 is connected to the storage chamber 322, and is provided with an air intake pipe 33; the upper housing 311 is provided with an adapter 38 for connecting the air intake pipe 33 and the connecting pipe 34. Specifically, a sleeve 361 is fixedly provided in the lower housing 312, and a detachable support seat 313 is provided, and the air intake pipe 33 is fixed on the support seat 313. The upper housing 311 is provided with an adapter 38 and a connecting hole 314 for installing the connecting pipe 34, and a cover 315 is detachably provided at the top of the upper housing 311, and a fixing column 316 which abuts against the adapter 38 is provided at the bottom of the cover 315, so that the adapter 38 can be effectively fixed. It can be seen from this that designing the housing 31 as a detachable structure can facilitate the assembly and disassembly of the various components in the housing 31, thereby facilitating the maintenance and / or cleaning of the various components.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, the body 1 is provided with a mounting portion 11, and a receiving slot 12 is provided beside the mounting plate, the handheld device 3 is detachably provided on the mounting portion 11, and the connecting pipe 34 is received in the receiving slot 12. Specifically, the body 1 and the handheld device 3 are detachable in a magnetic structure, that is, the body 1 is provided with a first magnetic portion (not shown in the figure), and the handheld device 3 is provided with a second magnetic portion 39 that matches the first magnetic portion, so that the body 1 and the handheld device 3 can be quickly disassembled and assembled. Of course, in other embodiments, the body 1 and the handheld device 3 can also be installed in other ways such as a snap-on connection.

[0032] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
