Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pump maintenance, in particular to a water removal device for a vacuum pump. Background Technique

[0002] A vacuum pump is a special industrial pump, mainly used to extract various gases and gas mixtures to form a high-vacuum or low-vacuum environment. In daily use, water vapor exists in the air or the working environment and enters the interior along with the operation of the vacuum pump. If the vacuum pump takes in too much water, it will cause serious harm to the equipment. For example, water is a high-density fluid. After entering the vacuum pump, it will increase its torque, resulting in an increased load on the vacuum pump and making the vacuum pump more likely to be damaged; the components of the vacuum pump are usually composed of metal materials and rubber seals. After water enters, the water will corrode the metal surface and damage the seals, causing the vacuum pump to fail to work properly; when water vapor evaporates in the vacuum pump, it will condense into water droplets and form a water film in the vacuum pump, reducing the vacuum degree of the vacuum pump and affecting the performance of the pump.

[0003] Therefore, it is necessary to remove water from the vacuum pump after daily use to prevent water droplets from settling and accumulating. However, traditional methods mostly use drying and air-drying, which takes too long and is prone to the risk of secondary water intake; using a hair dryer for drying also has limited effects. Firstly, the hair dryer has no pertinence and it is not easy to blow to the corners inside the vacuum pump. At the same time, some obvious water droplets are likely to flow into the gaps between components when being blown, which is likely to affect the components. For this reason, we have proposed a water removal device for a vacuum pump. Content of the Utility Model

[0004] The purpose of the utility model is to provide a water removal device for a vacuum pump to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A water removal device for a vacuum pump, including a handle shell, a cleaning rod, and a drying head. A high-speed hot air motor is arranged in the inner cavity of the handle shell, and an air inlet is opened at the top of the handle shell; a wire is connected to the handle shell and is used by plugging the plug into a socket, and a control button is also arranged on the handle shell;

[0006] The bottom of the handle shell is fixedly provided with a cleaning rod, an absorbent ring is fixedly sleeved on the outer side of the cleaning rod, and an absorbent layer is arranged on the surface of the absorbent ring; the absorbent layer includes any one of absorbent non-woven fabric, super absorbent cotton, and absorbent fiber. During use, the inner cavity of the vacuum pump is evenly brushed with the cleaning rod to absorb the internal moisture, and the surface and inner cavity of the vacuum pump that can be touched are rubbed once; a docking air outlet head is arranged at the bottom of the cleaning rod, and the docking air outlet head penetrates the cleaning rod and is communicated with the high-speed hot air blower;

[0007] A drying head is provided at the bottom of the cleaning rod. The drying head includes a direct blowing head and a hose blowing head, and the two drying heads are used alternately; docking grooves are provided at the tops of the direct blowing head and the hose blowing head, and the docking grooves are screwed and fixed to the docking air outlet head upward; a guiding air hose is provided at the bottom of the hose blowing head, and the top of the guiding air hose communicates with the inner cavity of the hose blowing head.

[0008] Further, a water absorption ring is movably sleeved outside the cleaning rod. Limiting rings are provided at the joints of the cleaning rod near both ends of the water absorption ring, so that the water absorption ring is restricted while rotating; a gear ring is provided at the top of the water absorption ring.

[0009] Further, a drying motor is provided on the front side of the handle shell. The shell of the drying motor is integrally formed with the handle shell but does not communicate with each other; the bottom of the drying motor is a transmission end, and a gear head extends downward from the transmission end. The gear head meshes with the gear ring downward. Starting the drying motor drives the gear head to rotate, drives the gear ring and the water absorption ring to rotate synchronously through the gear head, and throws the water droplets on the water absorption ring out by high-speed rotation. The water absorption ring is driven to rotate by the drying motor to dry the water, and it is convenient to use the water absorption ring for the second time after the water droplets on it are dried.

[0010] Further, the inner cavity of the drying head is hollow and communicates with the docking air outlet head through the docking groove; the direct blowing head and the hose blowing head have the same size.

[0012] Further, a fin air outlet is provided at the bottom of the direct blowing head, and evenly arranged guiding fins are provided in the fin air outlet to squeeze and accelerate the flowing air.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] This solution provides a device for removing water and cleaning a vacuum pump, which has two cleaning methods, including water absorption cleaning of a water absorption layer and drying cleaning of a high-speed hot air blower; large water droplets are contaminated on the water absorption layer to prevent them from being blown into the gaps of components. At the same time, a drying motor is provided, and the water absorption ring is driven to rotate and dehydrate by the drying motor, so that the purpose of quickly achieving secondary use can be achieved;
