EXPLOSION-PROOF FILTER CARTRIDGE

Abstract

An explosion-proof filter cartridge, that includes: a filter bottle, a filter nozzle, a filter cartridge, and a plurality of elastic balloons. The filter nozzle is disposed on an upper end of the filter bottle, the filter cartridge is disposed in the filter bottle. The plurality of elastic balloons are disposed on an inner wall of the filter bottle. The distance between the two elastic balloons is less than a diameter of the elastic balloon. The plurality of elastic balloons are disposed and distributed evenly on the inner wall of the filter bottle, to prevent explosion of the filter bottle when water in the filter bottle is frozen to ice.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0015] The purpose, construction, features, functions and advantages of the present invention can be appreciated and understood more thoroughly through the following detailed descriptions with reference to the attached drawings.

[0016] In the following, an embodiment is used to describe the various details of the present invention. However, it does not mean that this embodiment represents all the embodiments of the present invention. Other embodiments can be envisaged by people familiar with this field, and thus they all fall into the scope of the present invention.

[0017] Refer to FIGS. 1-3 respectively for a schematic diagram of an explosion-proof filter cartridge according to the present invention; a cross section view of an explosion-proof filter cartridge according to the present invention; and a cross section view of a filter cartridge according to the Prior Art.

[0018] As shown in FIGS. 1-2, the present invention provides an explosion-proof filter cartridge, comprising: a filter bottle 10; a filter nozzle 20, a filter cartridge 30, and a plurality of elastic balloons 40. The filter nozzle 20 is disposed on an upper end of the filter bottle 10, the filter cartridge 30 is disposed in the filter bottle 10. The plurality of elastic balloons 40 are disposed on an inner wall of the filter bottle 10.

[0019] In an embodiment of the present invention, the disposition of the plurality of elastic balloons 40 could prevent explosion of a filter bottle 10. When the temperature of the water in the filter bottle 10 drops to below zero degrees Celsius, the water in the filter bottle 10 is frozen into ice, the volume of the ice is increased, to press the filter bottle 10. Further, the elastic balloons 40 tend to contract by the pressure of the ice, hereby increasing the volume and space in the filter bottle to a certain extent. Further, at the same time, the pressed elastic balloons 40 will produce an elastic force, to buffer the pressure of the ice, thus averting the explosion of the filter bottle 10.

[0020] In an embodiment of the present invention, the plurality of elastic balloons 40 are disposed evenly on the inner wall of the filter bottle 10. As such, the pressure exerted on the filter bottle 10 is made to distribute evenly, to reduce the possibility of explosion.

[0021] In an embodiment of the present invention, the plurality of elastic balloons 40 are disposed into an array on the inner wall of the filter bottle 10. As such, the pressure exerted on the filter bottle 10 is made to distribute evenly to prevent explosion, while giving a sense of aesthetics.

[0022] In an embodiment of the present invention, a distance between the two elastic balloons 40 is less than a diameter of the elastic balloon 40. Since the elastic balloons 40 are disposed into an array on the inner wall of the filter bottle 10, thus they could form into a string. With the plurality of elastic balloons 40 placed along the vertical direction, to cover the upper end and lower end of the filter bottle 10, while a distance between the two elastic balloons 40 is less than a diameter of the elastic balloon 40.

[0023] In operation, when the water in the filter bottle 10 is frozen into ice, the elastic balloons 40 is made to contract by the pressure exerted by the ice. When the ice in the filter bottle 10 is unfrozen into water, the elastic balloons 40 will restore to their original positions.

[0024] The above detailed description of the preferred embodiment is intended to describe more clearly the characteristics and spirit of the present invention. However, the preferred embodiments disclosed above are not intended to be any restrictions to the scope of the present invention. Conversely, its purpose is to include the various changes and equivalent arrangements which are within the scope of the appended claims.
