Referring to fig. 1 to 12, a filter cartridge assembly 100 according to a first embodiment of the present invention includes a housing 110, a filter cartridge 130, and an elastic water stop valve 140.

The housing 110 has a first receiving chamber 112 formed therein for receiving the filter element 130, and the housing 110 has a rectangular parallelepiped structure or a cylindrical structure in order to ensure a large size and a filtering path of the filter element 130.

Of course, in some cases, the housing 110 may also be a special-shaped structure, and can be embedded with the internal structure of the water purifying apparatus, so as to achieve the purpose of saving space.

An installation part 120 is disposed at one end of the housing 110, and the installation part 120 protrudes from an end surface of the housing 110 and is used for connecting a water supply and drainage structure of a water purification apparatus. The mounting portion 120 and the housing 110 may be integrally formed, and an end portion of the housing 110 protrudes outward to form the mounting portion 120. When the mounting portion 120 and the housing 110 are integrally formed, the housing 110 has better sealing performance, lower manufacturing cost and higher production efficiency. The mounting portion 120 and the housing 110 may be independent components, and the mounting portion 120 is mounted on the housing 110 by a locking member and is connected to the housing 110 in a sealing manner. The housing 110 and the mounting portion 120 are separate bodies, which facilitates assembly of the internal structure of the filter cartridge assembly 100.

It is understood that when the mounting portion 120 and the housing 110 are integrally formed, a detachable rear cover is disposed at an end of the housing 110 far from the mounting portion 120. After the rear cover is opened, the filter element 130 can be placed in the first accommodating cavity 112, the rear cover is fixed on the housing, and the filter element 130 can be blocked in the first accommodating cavity 112.

In some embodiments, an end of the housing 110 away from the mounting portion 120 may be further provided with a decorative cover, and the decorative cover may cover a rear cover on the housing 110.

The one end that installation department 120 was kept away from to casing 110 is provided with handle portion 114, can carry out the installation and the dismantlement of filter element subassembly 100 through handle portion 114 during the use, and handle portion 114 has made things convenient for operating personnel to the gripping of filter element subassembly 100 and has exerted oneself, and is more convenient and nimble.

In some embodiments, a receiving groove 116 is formed at an end of the housing 110 away from the mounting portion 120, the handle portion 114 is rotatably connected to an end of the housing 110 away from the mounting portion 120, and the receiving groove 116 is suitable for receiving the handle portion 114.

It can be understood that, under the condition that the accommodating groove 116 is formed in the casing 110, the handle part 114 can be placed in the accommodating groove 116 when not in use, so that the space occupied by the handle part 114 is reduced, the size of the filter element assembly 100 is reduced, the structure of the water purifying equipment is more compact, and the use of the water purifying equipment in narrow spaces such as a kitchen is facilitated.

A first water guide opening 122, a second water guide opening 124 and a third water guide opening 126 are formed in the mounting portion 120, and the first accommodating chamber 112 is communicated with the outside through the first water guide opening 122, the second water guide opening 124 and the third water guide opening 126.

The filter element 130 is disposed in the first accommodating chamber 112, and is used for filtering tap water, domestic water, and the like to obtain purified water with a small total dissolved solid amount. A first flow passage 132 is formed between the filter element 130 and a sidewall of the first receiving chamber 112, and a second flow passage 134 is formed at the center of the filter element 130. The first flow passage 132 is in fluid communication with the first water directing port 122, the second flow passage 134 is in fluid communication with the second water directing port 124, and the end of the filter element 130 proximate the third water directing port 126 is in fluid communication with the third water directing port 126.

It can be understood that the first water guiding opening 122 receives raw water such as tap water, and the raw water has more impurities and larger total dissolved solid content, and cannot be drunk directly. The raw water reaches the outside of the filter element 130 along the first flow passage 132, flows toward the center of the filter element 130 by the external water pressure, and the filtered pure water is collected in the second flow passage 134 and then flows out along the second water guide port 124 for use by a user. When the filter element 130 filters raw water, impurities and soluble solid particles in the raw water can be blocked to form waste water in the filter element 130, the end portion of the filter element 130 is communicated with the third water guide port 126, and the waste water can be discharged out of the filter element assembly 100 along the third water guide port 126.

According to the filter element assembly 100 provided by the embodiment of the utility model, the first water guide opening 122, the second water guide opening 124 and the third water guide opening 126 are respectively provided with the elastic water stop valve 140, each elastic water stop valve 140 works independently, and the elastic water stop valve 140 has an open position and a closed position.

In the open position, the corresponding first water guide opening 122, second water guide opening 124 and third water guide opening 126 are in a water guide state;

in the closed position, the corresponding first water guide opening 122, second water guide opening 124 and third water guide opening 126 are in a water blocking state.

It is understood that, when the filter element assembly 100 is in normal operation, the elastic water stop valve 140 is in an open position under the action of other supporting structures, the first water guide opening 122 receives external tap water, the filter element 130 filters the tap water, the filtered pure water is discharged through the second water guide opening 124, and the waste water generated during filtering is discharged along the third water guide opening 126. The filter cartridge assembly 100 needs to be replaced after a period of use, and when the filter cartridge assembly 100 is removed, the elastomeric water stop valve 140 returns to the closed position. In the closed position, the corresponding first water guiding opening 122, second water guiding opening 124 and third water guiding opening 126 are in the water blocking state, and the residual water in the filter element assembly 100 cannot leak, so that the pollution to water purifying equipment and a cabinet is avoided, the phenomenon that sewage is splashed on the body of a user is avoided, and the filter element assembly 100 is cleaner and more sanitary and more convenient.

The elastic water stop valve 140 is located at the installation portion 120, and the filter element assembly 100 needs to avoid touching the elastic water stop valve 140 after being disassembled, so as to avoid leakage of residual water along the first water guide opening 122, the second water guide opening 124 and the third water guide opening 126.

According to some embodiments of the present invention, the cartridge assembly 100 further includes an end cap 170, the end cap 170 being mounted to the side of the mounting portion 120 remote from the housing 110. The end cap 170 is provided with a through hole 172 corresponding to the position of the elastic water stop valve 140, and a force can be applied to the elastic water stop valve 140 along the through hole 172.

It should be noted that the end of the water stop elastic valve 140 away from the housing 110 is concave or flush with respect to the plane of the end cap 170, i.e. the water stop elastic valve 140 does not exceed the plane of the end cap 170. After detaching the filter element assembly 100, when carrying the filter element assembly 100, the end cover 170 can shield the elastic water stop valve 140, the external structure can not directly contact the elastic water stop valve 140, water leakage of the filter element assembly 100 in the carrying process can be avoided, and the sealing performance of the filter element assembly 100 is improved.

In some embodiments, elastomeric water stop valve 140 includes a valve housing 142, a valve cap 144, a valve core 146, and an elastomeric member 148.

The valve housing 142 has a hollow structure, may have a cylindrical structure, or may have a polygonal frame structure, and the outer contour of the valve housing 142 is adapted to the inner wall contours of the first water guide opening 122, the second water guide opening 124, and the third water guide opening 126. An annular blocking portion 168 is formed on an inner wall of the valve housing 142 to block the valve core 146.

The valve cover 144 is connected to one end of the valve housing 142 to close off the end of the valve housing 142, and the valve cover 144 and the valve housing 142 combine to form a semi-closed chamber. The valve core 146 is disposed within the valve housing 142, and the valve core 146 is positioned between the valve cover 144 and the stop 168. It will be appreciated that the valve spool 146, after being installed in the valve housing 142, is confined to the area between the valve cover 144 and the stop 168 and does not escape the valve housing 142. In order to ensure the circulation of the liquid, the valve cover 144 is further provided with water through holes along which the liquid can circulate in a water guiding state.

A resilient member 148 is disposed within valve housing 142, and resilient member 148 is coupled at one end to valve cap 144 and at the other end to valve element 146 to move valve element 146 away from valve cap 144. When only the elastic member 148 acts, the valve core 146 abuts against the blocking portion 168, and the water flow can be blocked, and the elastic water stop valve 140 is in the closed position. When a force is applied to the valve core 146, the elastic member 148 is compressed, and the valve core 146 is away from the position of the blocking portion 168, and the elastic water stop valve 140 is in the open position. Accordingly, the elastic member 148 may switch the corresponding first water guide opening 122, second water guide opening 124, and third water guide opening 126 between the water guiding state and the water blocking state.

It can be understood that when the cartridge assembly 100 is connected to the body 200 of the water purifying device, the structure inside the body 200 supports the valve core 146, thereby allowing the cartridge assembly 100 to be in a water-guiding state. When the filter element assembly 100 is dismounted, the acting force applied on the valve core 146 is cancelled, the valve core 146 is abutted against the blocking part 168 under the action of the elastic part 148, and then the filter element assembly 100 is in a water-blocking state, residual water in the filter element assembly 100 cannot leak, and the cleanness and sanitation of the filter element assembly 100 are improved.

The elastic member 148 may be a spring, a steel plate, or the like.

In some embodiments, a side of the valve core 146 facing away from the elastic member 148 is provided with a pressing member 150, and the pressing member 150 is inserted into the blocking portion 168.

It will be appreciated that the contact element 150 may apply a force to the valve core 146, and that the contact element 150 may be disposed on the valve core 146 to facilitate the use of the cartridge assembly 100 with the housing 200. After the filter element assembly 100 is abutted to the machine body 200, the machine body 200 can apply an acting force to the contact pressing member 150, so that the effective communication between the filter element assembly 100 and the machine body 200 is ensured. Meanwhile, the contact pressing piece 150 also reduces the butt joint difficulty of the filter element assembly 100 and the machine body 200, after the filter element assembly 100 is installed at the corresponding position, a connecting pipe on the machine body 200 corresponds to the contact pressing piece 150, the position does not need to be corrected for many times, and the use is convenient.

In some embodiments, the outside of the touch element 150 is provided with a reinforcement 152, and the reinforcement 152 may increase the structural strength of the touch element 150.

It is understood that the number of the reinforcement portions 152 may be plural, and the reinforcement portions 152 are uniformly distributed outside the contact element 150. In some cases, the reinforcement portion 152 is a rib, and four ribs are distributed in a cross shape, and a flow channel is formed between the ribs. The reinforcement portion 152 not only increases the structural strength of the touch pressure member 150, but also does not affect the flow of the liquid inside the elastic water stop valve 140.

When the valve core 146 abuts against the blocking portion 168, the elastic water stop valve 140 is in the closed position, and the first water guide opening 122, the second water guide opening 124, and the third water guide opening 126 are in the water blocking state. The stability of the movement of the valve core 146 is increased, and the water blocking performance of the elastic water stop valve 140 is improved.

In some embodiments, the elastomeric water stop valve 140 further includes a first guide 154 and a second guide 156, the first guide 154 slidably coupled to the second guide 156.

The first guide 154 has opposite ends, and one end of the first guide 154 is connected to the valve cap 144 and the other end extends in the direction of the valve core 146. The second guide 156 has opposite ends, and one end of the second guide 156 is connected to the valve core 146 and the other end extends in the direction of the valve cover 144. The sliding connection of the first guide 154 and the second guide 156 ensures that the valve core 146 remains stable during movement.

It can be understood that the first guide 154 and the second guide 156 can slide relatively along a straight direction, and when the valve core 146 is far away from or close to the blocking portion 168, the valve core will not shake or have a position deviation, and can be accurately abutted on the annular blocking portion 168, which is beneficial to improving the water blocking performance of the elastic water stop valve 140.
