The electric vacuuming device of the present invention comprises: a casing assembly 11, a vacuum module 12, a nozzle member 13, a first airtight member 14, a second airtight member 15, and a triple battery 16.

The housing assembly 11 includes an upper cover housing 111, a first housing 112, a second housing 113 and a water blocking housing 114. The upper cover housing 111 includes a cover 111a. A base 111b and a switch member 111c, the cover 111a and the switch member 111c are disposed on the base 111b, and include two engaging holes 111a1 and an opening 111a2. The switch member 111c includes a button portion 111c1 having a pressing portion 111c2. A spring portion 111c3, a conductive portion 111c4, and a first contact portion E1 are provided corresponding to the button portion 111c1.

The first housing 112 includes a first air suction port 1121, an air flow groove 1122, two first fastening portions 1123, six first fitting grooves 1124, two second fitting grooves 1125, and four second fastenings. The first fastening portion 1123 is respectively engaged with the two fastening holes 111a1, and the second housing 113 includes six fitting portions 1131. The six fitting portions 1131 are respectively corresponding to the six first fittings. In the recess 1124, the water blocking housing 114 includes a second air outlet 1141, a four fastening slot 1142, and a mounting portion 1143. A fluid space S is formed between the water blocking housing 114 and the first housing 112. The two air suction ports 1141 are connected to the first air suction port 1121 and the fluid space S, and the four second fastening portions 1126 are respectively fastened to the four fastening grooves 1142.

The vacuum module 12 is disposed in the housing assembly 11 and includes an electric air pump 121 and a power receiving member 122. The electric air pump 121 is disposed on the power receiving member 122 and includes a suction portion 1211. The air portion 1212 and the second contact portion E2, the first air suction port 1121 corresponds to the air suction portion 1211, the venting portion 1212 corresponds to the airflow groove 1122 of the first housing 112. The power receiving member 122 has two protruding portions 1221 and correspondingly fit into the two second fitting grooves 1125 (only shown in the figure) A protruding portion 1221).

The nozzle member 13 is detachably disposed on the water blocking housing 114, and includes a third air suction port 131 and a mounting groove 132. The third air suction port 131 communicates with the second air suction port 1141, and the mounting portion of the water blocking housing 114. 1143 is correspondingly engaged in the mounting slot 132.

Next, the operation mode of the electric vacuum pumping device of the present invention will be described. The present invention uses the switch member 111c of the cover housing 111 of the housing assembly 11 to drive or stop the operation of the electric air pump 121. Specifically, as shown in FIG. 2 and As shown in FIG. 3, when the user presses the button portion 111c1, the pressing portion 111c2 abuts against the first contact portion E1 and is pressed down, and when the first contact portion E1 is pressed down against the second contact portion E2 When the electric air pump 121 receives the power supply and performs the pumping operation, when the user stops the pumping operation, the spring portion 111c3 pushes up the button portion 111c1, and the first contact portion E1 and the first portion are stopped. The two contact portions E2 are no longer in the abutting state, and the electric air pump 121 loses the power supply and stops the pumping operation.

When performing the pumping operation, as shown in FIG. 3, the air flow groove 1122 of the cover housing 111 of the housing assembly 11 causes the air discharged from the exhaust portion 1212 of the electric air pump 121 to recirculate, and the discharged air circulates and flows. In the housing assembly 11, the operating temperature of the electric air pump 121 is lowered, whereby the air flow groove 1122 can slow down the temperature rise when the electric air pump 121 is actuated to achieve a better heat dissipation effect.

As shown in FIG. 4, the suction portion 1211 of the electric air pump 121 is projected onto the bottom side surface of the water blocking housing 1145 to form a projection point P, and the second air suction port 1141 is formed at a position deviated from the projection point P. The electric air pump 121 is prevented from directly sucking in liquid or foreign matter. In detail, when the air in the air suction container is evacuated from the third air suction port 131 through the second air suction port 1141 into the fluid space S, the air can be made The liquid and foreign matter contained in the air are retained in the fluid space S, and the liquid and foreign matter are not directly sucked by the electric air pump 121, causing the electric air pump 121 to be damaged.

The first airtight member 14 disposed on the suction portion 1211 of the electric air pump 121 and the second airtight member 15 disposed between the first housing 112 and the water blocking housing 114 reinforce the fluid space S. The airtightness allows the pumping operation of the electric air pump 121 to be performed more efficiently.

The nozzle member 13 is made of silicone material, which helps to improve the airtightness when it comes into contact with the container to be evacuated, and prevents the gas from entering or dissipating from the gap of the attachment position when the vacuum pumping device performs the vacuuming operation. In addition, the diameter D of the third suction port 131 of the nozzle member 13 can be designed for different types of to-be-sucked containers, and the installation of the mounting portion 1143 and the nozzle member 13 of the water-retaining housing 114 The simple installation of the groove 132 allows the user to conveniently disassemble or install the nozzle member 13 having different diameters D on the water blocking housing 114 as needed.

In the assembly method, as shown in FIG. 5 and FIG. 6, the air intake portion 1211 of the electric air pump 121 is inserted into the first air suction port 1121 of the first housing 112, and the power receiving member 122 is also disposed. The protruding portion 1221 is embedded in the second fitting recess 1125 of the first housing 112, so that the vacuum module 12 is fixed on the first housing 112, and then the six fitting portions of the second housing 112 are assembled. After the 1131 is inserted into the first fitting recess 1124 of the first housing 112, the first fastening portion 1123 of the first housing 112 is fastened into the two fastening holes 111a1 of the upper cover housing 111, and After the second fastening portion 1126 of the first housing 112 is engaged in the four fastening slots 1142, the assembly of the electric vacuuming device of the present invention can be completed, that is, the assembly of the electric vacuuming device of the present invention. It can be assembled and disassembled without the need of a locking tool, which is very convenient in assembly work.

When the battery 16 is placed in the power receiving member 122 after the assembly is completed, only the first fastening portion 1123 needs to be pressed to remove the upper cover housing 111 and replace the battery 16, and the cleaning device is to be cleaned. When liquid or foreign matter accumulated in the fluid space S of the water casing 114 is required, the water-containing casing 114 can be detached and the cleaning operation in the fluid space S can be performed, which is convenient for maintenance.

As can be seen from the above, the housing assembly 11 of the electric vacuuming device of the present invention is assembled by interlocking or fitting the upper cover housing 111, the first housing 112, the second housing 113, and the water blocking housing 114. The assembly operation and maintenance of the electric vacuum pumping device are very fast and convenient, and the nozzle member 13 can also be freely disassembled and replaced with suitable sizes for different air suction containers, thereby greatly improving the convenience of the electric vacuum pumping device. Sex.
