Technical Field

[0001] The utility model relates to the technical field of filtering structures, in particular to a filter with high-definition sterilization and preheating. Background Art

[0002] The high-pressure steam sterilization method uses high temperature and high pressure for sterilization. It can not only kill ordinary bacteria, but also has a killing effect on bacterial spores. It is the most reliable and widely used physical sterilization method.

[0003] Before the device works, it is necessary to filter the steam before heating it with water to prevent impurities from mixing into the steam.

[0004] In the working process of the existing filtering structure, it is not convenient to clean the filter element, resulting in the filter element being blocked by foreign objects after being used for a period of time, which affects the filtering effect of the filter element.

[0005] Therefore, we propose a filter with high-definition sterilization and preheating to solve the existing problems. Content of the Utility Model

[0006] The purpose of the utility model is to propose a filter with high-definition sterilization and preheating for the problems existing in the background art.

One end of the casing is provided with a support cylinder through an installation component for extrusion positioning. An electric heating element is arranged radially in the support cylinder. A microporous cylinder is arranged outside the support cylinder. The other end of the casing is provided with a left cover, and the left cover is in sealed contact with one end of the support cylinder.

[0008] Preferably, a water inlet is opened on the casing, and a drain port is opened on the left cover. The opening of the drain port is inside the support cylinder. Sealing caps are threadedly installed at the end positions of the drain port and the water inlet.

[0009] Preferably, a cushion seat is installed on the left cover. One end of the support cylinder abuts against the cushion seat, and a sealing ring is arranged on the contact surface between the support cylinder and the cushion seat.

[0010] Preferably, sealing rings are arranged on the contact surface between the left cover and the casing and on the contact surface between the casing and the ring head.

[0011] Preferably, the installation component is composed of a right cover, a ring head and a ring. The ring is arranged on the outer surface of the casing. The ring head is installed on the support cylinder. The right cover is threadedly installed on the ring, and the ring head is between the casing and the right cover and is squeezed by both.

[0012] Preferably, an installation hole adapted to the electric heating element is formed in the ring head of the installation assembly, the electric heating element is inlaid and installed on the installation hole, and a plug is provided at one end of the electric heating element, and the plug is located on the outer surface of the ring head.

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

[0014] During the use of the filter with high-definition sterilization and preheating of the present utility model, the device can be interconnected with the water inlet pipeline of the high-pressure steam sterilizer. The steam water enters the casing through the water inlet, and under the action of water pressure, the water enters the support cylinder through the micropores on the microporous cylinder. At this time, the impurities in the water are filtered by the microporous cylinder and retained on the surface of the microporous cylinder;

[0015] Furthermore, when the water is inside the support cylinder, at this time, an external power supply is connected to make the electric heating element work to preheat it, and the water that has been filtered and preheated is sent into the water inlet assembly of the high-pressure steam sterilizer through the drain port;

[0016] When needed, the right cover can be rotated. Through the threaded engagement effect between the right cover and the ring on the casing, the right cover is moved away from the casing. At this time, the ring head is no longer blocked, and the support cylinder can be removed from the inside of the casing, so as to facilitate the cleaning of the surface of the microporous cylinder;
