[0027] See Figures 1 - 3 , the present utility model provides a water purifier housing assembly, including a housing 1 and a filter element support 2. An inner cavity 13 is formed inside the housing 1. A filter element installation hole 11 is opened on the front side wall of the housing 1, and the filter element installation hole 11 communicates with the inner cavity 13. A receiving groove 21 is opened on the top wall of the filter element support 2. The front and rear ends of the receiving groove 21 respectively penetrate through the front side wall and the rear side wall of the filter element support 2. The filter element support 2 is disposed in the inner cavity 13. The filter element support 2 and the top wall of the inner cavity 13 enclose a receiving cavity 23 for installing a filter element, and the receiving groove 21 is correspondingly disposed with the filter element installation hole 11. For the traditional filter element support 2 with openings at both the front and rear ends, a relatively long core-pulling structure needs to be provided on the mold of the filter element support 2 to injection-mold a long round hole, and the setting of a relatively long core-pulling structure will lead to a complex mold structure and a long injection time, resulting in a high cost of production and manufacturing; in the filter element support 2 of the present utility model, a receiving groove 21 is opened on the top wall, and the front and rear ends of the receiving groove 21 respectively penetrate through the front side wall and the rear side wall of the filter element support 2, forming a groove with openings on three sides, which simplifies the structure of the filter element support 2 of the water purifier, so that the mold of the filter element support 2 does not require a long core-pulling structure, thereby reducing the mold cost and the production cost; in the present solution, the filter element support 2 and the top wall of the inner cavity 13 enclose a receiving cavity 23 for installing a filter element, and the inner wall of the housing 1 is used as the top wall of the filter element support 2, saving the support material and reducing the material cost.

[0028] Specifically, the surrounding side walls of the receiving cavity 23 are of a closed structure, and there are through holes at the front and rear of the receiving cavity 23, which are respectively used for loading a filter element 3 and for connecting the filter element 3 with a water path connector.

[0029] Further, a first sealing edge 12 is formed by the hole wall of the filter element mounting hole 11 extending towards the interior of the housing 1. The filter element bracket 2 abuts against the bottom wall of the first sealing edge 12, and the front side wall of the filter element bracket 2 abuts against the front side wall of the inner cavity 13.

[0030] Further, a notch 22 is provided on the bottom wall of the accommodating groove 21. The notch 22 is located at the front end of the accommodating groove 21, and the first sealing edge 12 is placed in the notch 22. The cooperation between the first sealing edge 12 and the notch 22 can enable the filter element mounting hole 11 to quickly find the mounting position, so that the accommodating groove 21 can correspond to the filter element mounting hole 11 to form a complete mounting hole for installing the filter element 3.

[0031] Further, the cross-section of the accommodating groove 21 is U-shaped. When the filter element 3 is installed in the accommodating cavity 23, the outer side wall of the filter element 3 can be attached to the accommodating groove 21 to better support the filter element 3. The accommodating groove 21 is a U-shaped groove that runs through from front to back and is in the shape of a long strip, and its length matches the length of the filter element 3.

[0032] Specifically, the filter element 3 passes through the filter element mounting hole 11 and enters the accommodating cavity 23. The filter element 3 moves backward along the bottom wall of the accommodating groove 21 until it abuts against the waterway connector located at the rear. The accommodating groove 21 can play a guiding role for the filter element 3, enabling it to quickly connect with the waterway connector and realize the connection of the waterway; when the installation of the filter element 3 is completed, the bottom wall of the accommodating groove 21 can support the filter element 3 to prevent the filter element 3 from shifting.

[0033] Further, an opening is provided on the rear side wall of the housing 1. The opening is used for installing the waterway connector 4, and the opening communicates with the inner cavity 13. The filter element bracket 2 is fixedly connected in the inner cavity 13. The front and rear ends of the filter element bracket 2 respectively abut against the side wall of the inner cavity 13 and the waterway connector 4, clamping the filter element bracket 2 between the housing 1 and the waterway connector 4, thereby realizing the limiting and fixing of the filter element bracket 2. The installation of the filter element bracket 2 with the housing 1, the waterway connector 4, etc. is simple, and can achieve rapid assembly, which is beneficial to improving the production efficiency of the water purifier and reducing the production cost.

[0034] In one embodiment, the present utility model provides a water purifier, which includes the water purifier housing assembly as described above. Specifically, the water purifier housing assembly includes a housing 1 and a filter element support 2. An inner cavity 13 is formed inside the housing 1. A filter element installation hole 11 is provided on the front side wall of the housing 1, and the filter element installation hole 11 communicates with the inner cavity 13. A receiving groove 21 is provided on the top wall of the filter element support 2. The front and rear ends of the receiving groove 21 respectively penetrate through the front side wall and the rear side wall of the filter element support 2. The filter element support 2 is disposed in the inner cavity 13. The filter element support 2 and the top wall of the inner cavity 13 enclose a receiving cavity 23 for installing a filter element 3. The receiving groove 21 is correspondingly arranged with the filter element installation hole 11.

[0035] Compared with the traditional filter element support 2 with openings at both the front and rear ends, a longer core-pulling structure needs to be provided on the mold of the filter element support 2 to injection-mold a long round hole, resulting in a complex mold structure and a long injection time, leading to a high cost in production and manufacturing. In the filter element support 2 of the present utility model, a receiving groove 21 is provided on the top wall, and the front and rear ends of the receiving groove 21 respectively penetrate through the front side wall and the rear side wall of the filter element support 2, forming a groove with open sides on three sides, which simplifies the structure of the filter element support 2 of the water purifier, so that the mold of the filter element support 2 does not require a long core-pulling structure, thereby reducing the mold cost and the production cost. In the solution, the filter element support 2 and the top wall of the inner cavity 13 enclose a receiving cavity 23 for installing a filter element 3. The inner wall of the housing 1 is used as the top wall of the filter element support 2, saving the material of the filter element support 2 and reducing the material cost.

[0036] Further, the water purifier includes a waterway connector 4. The waterway connector 4 is disposed at the rear end of the inner cavity 13. The rear side wall of the filter element support 2 abuts against the waterway connector 4. The filter element support 2 is clamped between the housing 1 and the waterway connector 4, thereby realizing the limit and fixation of the filter element support 2. The installation of the filter element support 2 with the housing 1, the waterway connector 4, etc. is simple, and rapid assembly can be achieved, which is beneficial to improving the production efficiency of the water purifier and reducing the production cost.

[0037] Specifically, the waterway connector 4 covers the opening on the rear side wall of the housing 1. During installation, first, the filter element support 2 is inserted into the inner cavity 13 from the opening. By the inner wall of the notch 22 abutting against the bottom wall of the first sealing edge 12, the filter element support 2 can quickly find the installation position. Then, the filter element support 2 is further pushed forward until it abuts against the front side wall of the inner cavity 13. Finally, the waterway connector 4 is snapped into the opening on the rear side wall of the housing 1, and the waterway connector 4 clamps the filter element support 2 in the inner cavity 13 to realize the assembly of the waterway connector 4, the filter element support 2, and the housing 1.

[0038] Specifically, the waterway connector 4 is provided with a water inlet and a water outlet. The water inlet and the water outlet of the waterway connector 4 are respectively communicated with the filter element 3. The water inlet of the waterway connector 4 is communicated with the raw water port of the water purifier, and the water outlet of the waterway connector 4 is communicated with the water outlet of the water purifier. The water inlet of the waterway connector 4 conveys the raw water to the filter element 3 for filtration. The purified water filtered by the filter element 3 flows through the water outlet of the waterway connector 4 to the water outlet of the water purifier, realizing the filtration of water and providing purified water for people.

[0039] Further, the water purifier includes a filter element 3, and the filter element 3 is installed in the accommodating cavity 23. The filter element 3 is communicated with the waterway connector 4. The water inlet of the waterway connector 4 conveys the raw water to the filter element 3 for filtration. The purified water filtered by the filter element 3 flows through the water outlet of the waterway connector 4 to the water outlet of the water purifier.

[0040] In another embodiment, referring to Figure 4 , a supporting portion 24 is provided on the front side wall of the filter element bracket 2. A second sealing edge 25 extending in the direction of the filter element mounting hole 11 is provided on the top wall of the supporting portion 24. The top wall of the second sealing edge 25 abuts against the bottom wall of the first sealing edge 12. The accommodating groove 21 is a square groove. Since the filter element 3 is usually a cylindrical structure, the bottom wall of the accommodating groove 21 cannot directly support the filter element 3. The supporting portion 24 is provided to guide and support the filter element 3, realizing the installation of the filter element 3.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the protection scope of the invention.
