Description

Technical Field

[0001] This utility model belongs to the field of vacuum pump technology, specifically relating to a stable vacuum pump. Background Technology

[0002] In the tobacco processing flow, the vacuum system is one of the important pieces of equipment. The vacuum pump is used in the first process of cigarette production to send the tobacco leaves into the rehumidification box, seal it, and then use the vacuum pump to create a vacuum state to ensure that the moisture content of the tobacco shreds is about 21%, making the tobacco shreds elastic and easy to ignite.

[0003] Existing vacuum pumps filter the intake gas through a filter assembly. During operation, the filter body and filter canister are connected by threads, and the filter body and filter canister need to be disassembled multiple times to clean the filter elements inside the filter canister. When the filter canister is accidentally pushed, the connection between the filter body and filter canister becomes loose, resulting in insufficient installation stability. This affects the filtration effect of the vacuum pump during operation. Therefore, this utility model proposes a stable vacuum pump. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: a stable vacuum pump, including a tank 1 and a motor 2 disposed at the top of the tank 1. A filter assembly 4 is disposed on the front side of the motor 2. The filter assembly 4 consists of a filter body 41 and a filter tank 42. The bottom end of the filter body 41 is inserted into the inner side of the filter tank 42 and connected by threads. A limiting mechanism is provided at the connection between the filter body 41 and the filter tank 42 to increase the connection stability. The limiting mechanism consists of a groove assembly 411, a mounting post 412, and a limiting assembly 413. The groove assembly 411 consists of a mounting groove 4111 and a movable groove 4112. The mounting groove 4111 is opened on the side of the filter body 41, and the movable groove 4112 is opened on the inner wall of the filter tank 42. The mounting post 412 is disposed inside the mounting groove 4111 and the movable groove 4112. The limiting component 413 is disposed at the end of the mounting post 412 and the end of the movable groove 4112. The positions of the mounting groove 4111 and the movable groove 4112 are configured such that when the bottom end of the filter body 41 is inserted into the inner side of the filter tank 42 and fixed by a threaded connection, the mounting groove 4111 and the movable groove 4112 are connected to each other so that the mounting post 412 can enter or exit the mounting groove 4111.

[0025] The designed limiting mechanism improves the filtration effect of the vacuum pump when the connection between the filter body 41 and the filter canister 42 becomes loose. By adding a limiting mechanism to the installation points of the filter body 41 and the filter canister 42, the installation stability of the filter body 41 and the filter canister 42 is increased, ensuring the filtration effect of the vacuum pump on the intake gas during operation. The mounting column 412 has a cylindrical structure, and the diameter of the mounting groove 4111 is the same as the diameter of the movable groove 4112. The limiting assembly 413 consists of a limiting block 4131 and a limiting groove 4132. A limiting groove 4132 is formed inside the filter tank 42, and the limiting groove 4132 is in communication with the movable groove 4112. The limiting component 413 restricts the range of motion of the mounting column 412, and facilitates the rotation of the mounting column 412 by pushing the limiting block 4131, so that the mounting column 412 can move inside the mounting groove 4111 and the movable groove 4112, thereby realizing the limiting and non-limiting operation after the initial connection of the filter body 41 and the filter tank 42. The limiting block 4131 is set inside the limiting groove 4132, and the limiting block 4131 has a cylindrical structure. The diameter of the limiting block 4131 is the same as the diameter of the limiting groove 4132. An operator 3 is provided between the motor 2 and the filter component 4, and the operator 3 is installed on the surface of the tank 1. An air inlet is provided on the side of the tank 1, and an exhaust port is provided at the bottom of the tank 1. When the vacuum pump is operated through the air inlet and the air outlet, gas is drawn in through the air inlet and then discharged through the air outlet.

[0026] In this embodiment, preferably, the top of the filter tank 42 is provided with an operating groove 4132A, which communicates with the limiting groove 4132. The operating groove 4132A is located on the side of the limiting block 4131. The operating groove 4132A facilitates the operator to push the limiting block 4131 to achieve rotation of the limiting block 4131. The mounting post is configured to be threadedly connected to the mounting groove 4111 and the movable groove 4112.

[0027] The working principle and usage process of this utility model are as follows: When it is necessary to install the filter body 41 and the filter canister 42, after initially screwing and rotating the filter body 41 and the filter canister 42 into place, insert a finger into the inner side of the operating groove 4132A to push the limiting block 4131, causing the limiting block 4131 to rotate inside the limiting groove 4132. Simultaneously, this causes the mounting column 412 to rotate inside the movable groove 4112 and move forward along the thread of the movable groove 4112, so that the end of the mounting column 412 rotates to the inner side of the mounting groove 4111, achieving a threaded connection and fixation. This secondary fixation of the filter body 41 and the filter canister 42 through the limiting mechanism increases the assembly stability between the filter body 41 and the filter canister 42, thereby ensuring the filtration effect when the vacuum pump draws in air. When the vacuum pump is operating, the motor 2 serves as the power source, allowing air to be drawn into the inner side of the canister 1 through the air inlet installed on the side of the filter assembly 4, and then discharged through the exhaust port.

[0028] When it is necessary to release the restriction between the filter body 41 and the filter tank 42, insert your finger into the inside of the operating groove 4132A and push the limiting block 4131 in the opposite direction. This will cause the limiting block 4131 to rotate in the opposite direction inside the limiting groove 4132, and simultaneously drive the mounting column 412 to rotate in the opposite direction inside the movable groove 4112 and move backward along the thread of the movable groove 4112 until the end of the mounting column 412 exits the mounting groove 4111.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
