Detailed Description
In order to further explain the technical scheme of the invention, the invention is explained in detail by specific examples.
As shown in fig. 1 to 12, the invention discloses an environment-friendly long-life antifreezing filter, which comprises a filter body 1 with a water inlet 11 and a water outlet 12, a filter element assembly 2 arranged in the filter body 1 and a sealing cavity assembly 3 arranged in the filter element assembly 2.
Fig. 1 to 9 illustrate a preferred embodiment of the present invention, in which the specific structure of the filter body 1 and the filter element assembly 2 is only one embodiment of the filter, and the structure of the filter is not limited thereto. In this embodiment, the filter body 1 includes a body upper shell 13 and a body lower shell 14, the body upper shell 13 and the body lower shell 14 are detachably matched together, the body upper shell 13 is provided with the water inlet 11, the water inlet 11 is communicated with the filter element assembly 2, the water outlet 12 is shown as being arranged on the body upper shell 13, and of course, the water outlet 12 can also be arranged on the body lower shell 14 according to specific requirements.
In this embodiment, the filter element assembly 2 includes a cylindrical filter screen skeleton 21 and a filter screen 22 fitted around the filter screen skeleton 21, the water inlet 11 of the filter body 1 is connected to the filter screen skeleton 21, the seal cavity assembly 3 is disposed in the filter screen skeleton 21, and the outer Zhou Waijing of the seal cavity assembly 3 is smaller than the inner diameter of the filter screen skeleton 21, so that the water passing gap A is formed between the seal cavity assembly 3 and the filter screen skeleton 21.
In this embodiment, the sealed cavity assembly 3 includes a cavity 31 and a movable cover 32, the cavity 31 has a cavity 311 with a bottom seal and an opening at the top, the movable cover 32 is movably sealed in the cavity 311 of the cavity 31, the movable cover 32 is provided with at least one sealing ring 33 at the periphery, and the sealing ring 33 forms an interference fit with the inner wall of the cavity 311 of the cavity 31, so that the movable cover 32 is sealed in the cavity 311 of the cavity 31. The bottom of the cavity 31 is provided with a blocking wall 312, the periphery of the blocking wall 312 is in interference fit with the inner wall of the filter screen skeleton 12, and the periphery of the blocking wall 312 can be matched with a sealing ring 33, so that the cavity 31 and the filter screen skeleton 12 can be firmly matched together. In the preferred embodiment, the movable cover 32 is provided with a valve core 34, the valve core 34 is fixed on the movable cover 32 in a threaded connection manner, one end of the valve core 34 protrudes from the top end of the movable cover 32, and the other end extends into the cavity 311 of the cavity 31.
As shown in fig. 7 to 9, in the invention, a sealed cavity assembly 3 is added in the filter, the volume of a containing cavity 311 of the sealed cavity assembly 3 can be changed by moving a movable cover 32, and a sealing ring 33 is arranged on the movable cover 32 and the containing cavity of the cavity 31 forms a seal, so that water does not enter the cavity 31. As shown in fig. 7, the internal and external pressures of the movable cover 32 are balanced without water, and the movable cover 32 is at the original position. As shown in fig. 8, in the water-passing state, the movable cover 32 moves downward by a certain distance under the action of the water pressure, and at this time, the water pressure and the pressure inside the cavity 311 of the cavity 31 are balanced with each other. As shown in fig. 9, the filter freezes under the condition of a certain water pressure or no water pressure, at this time, the expansion force generated by the freezing pushes the movable cover 32 to move downwards, and the volume increased by the freezing and the volume of the vacant space B at the top of the cavity 31 increased by the movement of the movable cover 32 cancel each other. Thereby reducing the impact of the expansion force generated by icing on the filter body 1 and the filter element assembly 2, and realizing the purpose of protecting the filter from cracking. When the ice melts, the movable cover 32 can move upwards to reset under the action of air in the cavity 31.
In order to enable the movable cover 32 of the sealed cavity assembly 3 to quickly reset after moving towards the bottom of the accommodating cavity 311 of the cavity 31, in the preferred embodiment shown in fig. 1 to 9, a valve core 34 is additionally arranged on the movable cover 32 to form a one-way valve, and when the movable cover 32 moves downwards under the action of water pressure, gas is conveyed into the accommodating cavity 311 through the valve core 34, so that the pressure in the accommodating cavity 311 is increased; when the water pressure disappears, the movable cover 32 is pushed upwards until the internal pressure of the cavity 311 is balanced with the external pressure of the cavity 311 because the air pressure in the cavity 311 is greater than the air pressure outside the cavity 311.
As shown in fig. 10, in the second embodiment of the sealed cavity assembly 3 of the present invention, when the movable cover 32 is forced to move towards the bottom of the cavity 311, the air in the cavity 311 is compressed, so that the pressure in the cavity 311 is increased, and when the external force is eliminated, a pressure difference is formed between the inside and the outside of the cavity 311, so that the movable cover 32 is forced to move upwards, and therefore, the movable cover 32 may not be provided with a valve core.
As shown in fig. 11, in the third embodiment of the sealed cavity assembly 3 of the present invention, in this embodiment, the movable cover 32 is not provided with the valve core 34, but a spring 35 is provided in the cavity 311, and when the movable cover 32 moves downward under force, the spring 35 is compressed, and when the external force disappears, the spring 35 resets to push the movable cover 32 to quickly reset.
As shown in fig. 12, in a fourth embodiment of the sealed cavity assembly 3 of the present invention, in this embodiment, the movable cover 32 is provided with a valve core 34, and a spring 35 is also provided in the accommodating cavity 311, which is also convenient for resetting the movable cover 32.
The sealed housing assembly 3 may alternatively be provided with air pressurized within the chamber 311 in addition to the four embodiments listed above, for example, the chamber 311 may be configured as a full gas filled capsule with or without pressurization of the chamber 311.
The filter is characterized in that a sealed cavity component is additionally arranged in the filter element component, a movable cover of the sealed cavity component can move in a containing cavity of the cavity, so that a movable space is increased for the filter, and in the freezing process of water in the filter, the movable cover is pushed to move towards the bottom of the containing cavity of the cavity due to the ice-forming expansion force of the water, so that the volume of water or ice stored in the filter can be increased through the movement of the movable cover, the pressure of the freezing expansion force on the filter is reduced, and the risk of rupture of the filter is reduced. In addition, the filter assembly and the sealing cavity assembly inside the filter can be disassembled and cleaned, the whole filter is not required to be replaced, products can be recycled, the environment is protected, the damage to the filter caused by icing can be avoided, and the service life of the products is ensured.
The above examples and drawings are not intended to limit the form or form of the present invention, and any suitable variations or modifications thereof by those skilled in the art should be construed as not departing from the scope of the present invention.
