Description

Technical Field

[0001] The utility model relates to the technical field of air blocking devices, in particular to an air blocking device. Background Art

[0002] Air blocker (also known as sanitary anti-backflow floor drain, air blocker, air blocker) is designed and manufactured based on the structural characteristics of imported clean floor drains, combined with domestic actual conditions, using stainless steel material. It successfully solves technical problems such as dredging, cleaning, water sealing, and air sealing. It is a clean floor drain for various purification plants and clean rooms (GMP certification), and is mainly used in the chemical, petroleum, electricity, pharmaceutical, beer, food, dairy beverages and laboratories. It is an indispensable clean accessory.

At this time, manual deflation is required, and opening the sealed port of the air blocker is often troublesome. Therefore, a new type of air blocker is needed to solve the above problem.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0018] The present application provides an air blocking device, which is mainly used to solve the problem that during the use of the air blocker, when water enters from the inlet and flows out from the outlet, air will be left inside the air blocker. After a period of continuous use, there is more air inside the air blocker, and the interior is in a sealed state. The water level at the water outlet will be lowered by the air pressure. At this time, manual deflation is required, and opening the sealed port of the air blocker is often troublesome. The following technical solutions are provided. Figure 1-Figure 4 Make a detailed description:

[0019] An air blocking device comprises: a cavity 1 with a water inlet groove 2 and a water outlet groove 3 on the top, the water inlet groove 2 and the water outlet groove 3 are connected, the inner wall of the water inlet groove 2 is provided with a water inlet 4, and the inner wall of the water outlet groove 3 is provided with a water outlet 5, so that water enters through the water inlet 4, and after the air is removed, it flows through the water inlet groove 2 and the water outlet groove 3 and then flows out from the birth outlet, the inner walls of the water inlet 4 and the water outlet 5 are provided with threaded grooves for connecting an external water pipe, the inner wall of the water outlet groove 3 is fixedly penetrated with an air vent block 6, the surface of the air vent block 6 is provided with an air vent 7, and the inner wall of the air vent 7 is slidably plugged with an air blocking block 8, also includes a force-applying mechanism 9 for applying a force to the air blocking block 8 to maintain its original position and a sealing mechanism 10 for sealing the top of the cavity 1, wherein the force-applying mechanism 9 is mainly composed of: a force-applying rod 901 fixedly mounted on the surface of the air-deflating block 6, a force-applying ring 902 fixedly mounted on the surface of the air-deflating block 6, the force-applying rod 901 is slidably inserted into the inner wall of the force-applying ring 902 and a spring 903 in a stretched state is slidably sleeved on the surface, under the action of the spring 903, the force-applying rod 901 can drive the air-deflating block 6 to apply a resisting force to the air-deflating port 7, thereby avoiding gas leakage when deflation is required. The deflation operation can be performed by pulling the force rod 901, and the two ends of the spring 903 are respectively fixedly installed on the surface of the force rod 901 and the force ring 902, wherein the main components of the sealing mechanism 10 are: an external threaded tube 1001 fixedly sleeved on the surface of the cavity 1, a cover 1002 is threadedly sleeved on the surface of the external threaded tube 1001, and a transparent block 1003 for checking the internal situation of the cavity 1 is slidably inserted into the inner wall of the external threaded tube 1001.

[0020] When in use, the user passes water into the water inlet 4. After the water falls from the water inlet 4, the air will float to the top of the cavity 1 due to its lower density, thereby removing the gas in the water. Because the cavity 1 is sealed by the sealing mechanism 10, the water pressure flowing out of the water outlet 5 remains unchanged. This is the basic principle of the common air blocker. The device is provided with an air blocking block 8 slidably plugged into the inner wall of the air vent 7, and has the function of a force-applying mechanism 9. Therefore, in the absence of external force, the gas cannot flow out of the air vent 7. When someone pulls the air blocking block 8, the gas will be discharged from the air vent 7, thereby avoiding the problem that the water level of the water outlet 5 is lowered due to excessive air pressure inside the cavity 1, affecting the normal water flow transmission.
