[0038] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model embodiment provides a vacuum adsorption module for use in a handheld mixer. The vacuum module includes:

[0039] Housing assembly 1;

[0040] A diaphragm air pump 2 is located inside the housing assembly 1, and the upper end of the drive shaft 17 extends out of the housing assembly 1 for connection with the stirrer 18 in the handheld mixer. The lower end of the diaphragm air pump 2 is provided with an air inlet pipe 3 and an exhaust pipe 4 that are interconnected.

[0041] The housing assembly 1 is provided with an air intake structure and an air exhaust structure that are connected to the outside. The air intake structure is connected to the air intake pipe 3, and the air exhaust structure is connected to the air exhaust pipe 4.

[0042] The bottom of the housing assembly 1 is connected to a silicone suction nozzle 14 for sealing connection with the vessel to be vacuumed, and an oil seal 16 is provided between the upper end of the drive shaft 17 and the housing assembly 1. For example, the oil seal 16 is sleeved on the upper end of the drive shaft 17 based on its central hole.

[0043] When the vacuum adsorption module is put into use, it is mounted on the container to be vacuumed via the silicone suction nozzle 14. Then, the stirrer 18 is connected and locked to the drive shaft 17 at the upper end of the vacuum adsorption module. After that, the stirrer 18 is started, which drives the diaphragm air pump 2 in the vacuum adsorption module to vacuum the container. When the vacuuming is complete, simply separate the stirrer 18 from the vacuum adsorption module and remove the vacuum adsorption module from the container. The operation is convenient.

[0044] Based on the above, it can be seen that the vacuum adsorption module in this embodiment has a simple overall structure and is detachably connected to the stirrer, which facilitates subsequent cleaning and maintenance. Moreover, it enables the handheld stirrer to have vacuum capabilities, enriches the functions of the handheld stirrer, meets the diverse needs of users, and improves the user experience.

[0045] Furthermore, in combination Figures 2 to 5 As shown, in this embodiment, the diaphragm air pump 2 has a gas transmission channel between the air inlet pipe 3 and the exhaust pipe. The air intake structure, air inlet pipe 3, gas transmission channel, exhaust pipe 4, and exhaust structure are interconnected. The gas drawn in is discharged sequentially through the air intake structure, air inlet pipe 3, gas transmission channel, exhaust pipe 4, and exhaust structure.

[0046] In this embodiment, the housing assembly 1 includes an upper housing 5 and a lower housing 6. The lower housing 6 is provided with the air intake structure and the air exhaust structure. As shown in the figure, the upper housing 5 is cylindrical with an open lower end. The lower housing 6 covers the open end of the upper housing 5, and the diaphragm air pump 2 is encapsulated inside the housing assembly 1. The air intake structure and the air exhaust structure are located on the lower housing 6.

[0047] In this embodiment, the air intake structure includes an air inlet 7 formed on the lower housing 6. The air intake pipe 3 corresponds vertically to the air inlet 7 and is interconnected. Specifically, in this embodiment, to achieve the connection between the air intake pipe 3 and the air inlet 7, the air inlet 7 is extended towards the air intake pipe 3 to form a connector. Then, a connecting pipe 8 is used to connect the connector and the air intake pipe 3, thereby connecting the air intake pipe 3 and the air inlet 7.

[0048] Furthermore, in this embodiment, the vacuum adsorption module also includes a pressure plate disposed inside the housing assembly 1 and connected to the lower end of the diaphragm air pump 2. The pressure plate 10 has through holes at the corresponding air inlet pipe 3 and exhaust pipe 4. The air inlet pipe 3 and exhaust pipe 4 at the lower end of the diaphragm air pump 2 pass through the pressure plate 10 through the corresponding through holes.

[0049] The through hole corresponding to the exhaust pipe 4 on the cover plate has an inner diameter larger than the outer diameter of the exhaust pipe 4. An air pipe 11 is fitted over the exhaust pipe 4, and the exhaust pipe 4 is sealed to the through hole via the air pipe 11. In this embodiment, the exhaust pipe 4 and the drive shaft 17 are collinear, both located on the center line of the housing assembly 1. The intake pipe 3 is located beside the exhaust pipe 4 and parallel to it.

[0050] To prevent the discharged gas from leaking into the diaphragm pump 2, a limiting structure 12 is provided on the lower housing 6 corresponding to the exhaust pipe 4. The specific structure of the limiting structure 12 is not limited; in this embodiment, the limiting structure 12 is formed by a ring of baffles as shown in the figure. A sealing cover 13 is provided on the outer sleeve of the air pipe. The sealing cover 13 matches the shape of the limiting structure 12 so that it can cover the limiting structure 12 and seal it, forming an exhaust chamber between the limiting structure 12 and the sealing cover 13. The exhaust structure includes an exhaust hole 9 opened on the lower housing 6. The exhaust hole 9 is specifically opened on the lower housing 6 located inside the limiting structure 12, that is, within the exhaust chamber. The gas discharged through the exhaust hole 9 flows into the exhaust chamber and is discharged from the housing assembly 1 through the exhaust hole 9.

[0051] In this embodiment, the housing assembly 1 is further provided with an air pump valve 15 for detecting the negative pressure value in the vacuum vessel to be evacuated. The air pump valve 15 can automatically shut off the diaphragm air pump 2 and stop evacuating when the negative pressure in the vacuum vessel to be evacuated meets the requirements, such as -55KPA.

[0052] This utility model provides a handheld mixer, including a mixer and a vacuum adsorption module as described above, wherein the vacuum adsorption module is detachably connected to the mixer.

[0053] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this utility model.
