Description

Technical Field

[0001] The present invention relates to a water purifier, and more particularly to a method for manufacturing a housing for a water purifier. Background Art

[0002] A water purifier, also known as a water purification machine, can purify raw water (e.g., tap water) according to the requirements of users so as to meet people's needs. In many countries, especially in developing countries, with the continuous development of industry and agriculture, the problem of water pollution is becoming more and more serious, and the water sources for people's domestic water are more or less affected. In addition, the quality of tap water is also affected by the external environment and water supply pipelines. For example, excessive sand in the tap water source, aging of the pipe network, poor quality of the tap water pipes, and lack of cleaning of the water supply pipe network for a long time will all affect the quality of tap water. Therefore, under the influence of many factors, the quality of tap water in many countries is poor and not suitable for direct drinking. Through the filtering function of its purification device, the water purifier can effectively remove impurities such as sediment, colloid, rust, bacteria, and even heavy metal ions in the raw water, thereby improving and enhancing the quality of domestic water, and it is increasingly favored by consumers. Existing household water purifiers for purifying tap water mainly include under-sink ultrafiltration water purifiers, RO membrane water purifiers, water purifiers, water softeners, etc.

[0003] Water purification materials for a water purifier (or water purification machine) to treat raw water, such as ultrafiltration membrane filaments, activated carbon, etc., are all placed inside the housing of the water purifier. After the raw water flows through the water purification materials, it is purified to obtain purified water. Raw water, especially tap water, has a relatively large water pressure itself. After the raw water to be treated flows into the housing of the water purifier, the water pressure will act on the housing of the water purifier, and the housing of the water purifier needs to bear pressure for a long time. In addition, the water pressure of tap water often fluctuates, and the water hammer generated by the water pressure fluctuation will also act on the housing of the water purifier. In other words, the housing of the water purifier should have good flexibility to prevent it from cracking after being under long-term pressure or being affected by water hammer, and to ensure the safe use of the water purifier. Therefore, many existing housings for water purifiers have good flexibility. In addition, considering the manufacturing cost, many existing housings for water purifiers are made of materials with good flexibility but are opaque.

[0004] The housing for a water purifier made of an opaque material, although having good flexibility, is not convenient for users to check the usage status of the filter element of the water purifier. For example, many users are very concerned about whether the water purification material has accumulated dirt and turned yellow or black due to long-term use, so as to replace the filter element in time. In order to meet the needs of users to observe the usage status of the water purifier at any time and replace the filter element in time, many manufacturers use transparent materials to manufacture the housing for the water purifier. However, most transparent materials, such as AS, transparent ABS, PET, etc., are too rigid and lack flexibility. When subjected to the long-term action of external stress or the water hammer action caused by water pressure changes, they are prone to breakage. In order to ensure the safe use of the water purifier, manufacturers have to increase the thickness of the housing of the water purifier or use special expensive transparent materials that can withstand stress for a long time, resulting in a significant increase in its manufacturing cost.

[0005] Therefore, there is a need in the market for a housing for a water purifier that can withstand water pressure, stress, and water hammer action for a long time to ensure the safe use of the water purifier, is convenient for users to observe the usage of the water purification material inside the housing of the water purifier, and has a low price. Summary of the Invention

[0006] The main advantage of the present invention is to provide a housing for a water purifier that can withstand long-term water pressure and the water hammer action caused by water pressure changes, and has a low manufacturing cost.

[0007] Another advantage of the present invention is to provide a housing for a water purifier, which includes a first transparent housing and a second transparent housing, wherein the first transparent housing at least partially covers the outer surface of the second transparent housing, and the first transparent housing and the second transparent housing are integrally formed. Both the first transparent housing and the second transparent housing are made of transparent materials, and the elongation at break of the transparent materials of the first transparent housing and the second transparent housing is different, so as to achieve the structural complementarity between the first transparent housing and the second transparent housing and improve the anti-water hammer performance of the entire housing.

[0008] Another advantage of the present invention is to provide a method for manufacturing a housing for a water purifier, through which the housing for the water purifier included has excellent anti-water hammer performance.

Detailed implementation manners

[0049] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description of the present invention can be applied to other implementation schemes, variant schemes, improvement schemes, equivalent schemes, and other technical schemes that do not depart from the spirit and scope of the present invention.

[0050] Those skilled in the art should understand that in the disclosure of the present invention, the orientation or positional relationships indicated by the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.

[0051] It can be understood that the term "a" should be construed as "at least one" or "one or more". That is, in one embodiment, the number of one element can be one, while in other embodiments, the number of this element can be multiple. The term "a" should not be construed as limiting the quantity.

[0052] Referring to the accompanying drawings of the specification Figures 1A to 1D, the housing for a water purifier according to an embodiment of the present invention is illustrated, wherein the housing for a water purifier according to an embodiment of the present invention includes a first transparent housing 10V and a second transparent housing 20V, wherein the first transparent housing 10V at least partially covers the outer surface 201V of the second transparent housing 20V, and the first transparent housing 10V and the second transparent housing 20V are integrally formed, wherein the second transparent housing 20V forms a water treatment chamber 210V, and the first transparent housing 10V and the second transparent housing 20V have different light transmittances. Generally, materials with different light transmittances also have different elongation at break. It can be understood that the water treatment chamber 210V formed by the second transparent housing 20V of the housing for a water purifier according to an embodiment of the present invention is used to accommodate water treatment materials therein for purifying the raw water entering the water treatment chamber 210V. Therefore, the second transparent housing 20V of the housing for a water purifier according to an embodiment of the present invention is vulnerable to the water hammer effect caused by the change in water pressure of the raw water (or tap water). Preferably, the flexibility (or rigidity) of the first transparent housing 10V and the second transparent housing 20V of the housing for a water purifier according to an embodiment of the present invention is different, so that the first transparent housing 10V and the second transparent housing 20V can form a complementarity and can integrally provide better support for the raw water contained in the water treatment chamber 210V. In other words, the different flexibilities of the first transparent housing 10V and the second transparent housing 20V of the housing for a water purifier of the present invention can make the housing for a water purifier of the present invention as a whole provide better support for the raw water contained in the water treatment chamber 210V. More preferably, the flexibility of the second transparent housing 20V of the housing for a water purifier according to an embodiment of the present invention is better than the flexibility of the first transparent housing 10V. Most preferably, the elongation at break of the second transparent housing 20V of the housing for a water purifier according to an embodiment of the present invention is greater than the elongation at break of the first transparent housing 10V, to ensure that the water pressure borne by the second transparent housing 20V can be better transmitted to the first transparent housing 10V and to enable the complementary effect formed by the first transparent housing 10V and the second transparent housing 20V to better counteract the water hammer formed by the raw water in the water treatment chamber 210V.

[0053] As shown in the accompanying drawings Figures 1A to 1DAs shown, the first transparent housing 10V of the housing for a water purifier according to an embodiment of the present invention includes a first main body portion 11V and a first opening portion 12V, and the second transparent housing 20V includes a second main body portion 21V and a second opening portion 22V. The first opening portion 12V of the first transparent housing 10V extends integrally from the first main body portion 11V, and the second opening portion 22V of the second transparent housing 20V extends integrally from the second main body portion 21V. The first opening portion 12V of the first transparent housing 10V forms a first opening 120V, and the second opening portion 22V of the second transparent housing 20V forms a second opening 220V. The first opening 120V of the first opening portion 12V of the first transparent housing 10V and the second opening 220V of the second opening portion 22V of the second transparent housing 20V face the same direction. The first main body portion 11V of the first transparent housing 10V covers the second main body portion 21V of the second transparent housing 20V, and the second opening portion 22V of the second transparent housing 20V is partially covered by the first opening portion 12V of the first transparent housing 10V. Accordingly, the first main body portion 11V of the first transparent housing 10V and the second main body portion 21V of the second transparent housing 20V are integrally formed, and the first opening portion 12V of the first transparent housing 10V and the second opening portion 22V of the second transparent housing 20V are integrally formed, so that the first opening portion 12V of the first transparent housing 10V covers the neck portion 2201V of the second opening portion 22V of the second transparent housing 20V. Accordingly, the second opening portion 22V of the second transparent housing 20V protrudes outward from the first opening 120V of the first opening portion 12V of the first transparent housing 10V, and the first opening portion 12V of the first transparent housing 10V covers the neck portion 2201V of the second opening portion 22V of the second transparent housing 20V.

[0054] As shown in the accompanying drawings Figures 1A to 1D As shown, the second opening portion 22V of the second transparent housing 20V of the housing for a water purifier according to an embodiment of the present invention further includes a head portion 2202V. The neck portion 2201V of the second opening portion 22V extends outward from the second main body portion 21V, and the head portion 2202V of the second opening portion 22V extends outward from the neck portion 2201V and protrudes outward from the first opening 120V of the first opening portion 12V of the first transparent housing 10V. As shown in the accompanying drawings Figures 1A to 1DAs shown, further, the longitudinal sections of the first main body portion 11V of the first transparent housing 10V and the second main body portion 21V of the second transparent housing 20V of the housing for a water purifier according to an embodiment of the present invention are both "U" - shaped, so that the first main body portion 11V of the first transparent housing 10V and the second main body portion 21V of the second transparent housing 20V can form a "U" - shaped double - layer structure. Therefore, the longitudinal sections of the first transparent housing 10V and the second transparent housing 20V of the housing for a water purifier according to an embodiment of the present invention are both "U" - shaped, so that the longitudinal section of the housing for a water purifier according to an embodiment of the present invention as a whole has a "U" - shaped double - layer structure.

[0055] As shown in the attached drawings Figures 1A to 1D As shown, the housing for a water purifier according to an embodiment of the present invention further includes a lid 40 and a seal 50, wherein the seal 50 is water - sealedly arranged between the lid 40 and the product formed integrally by the first transparent housing 10V and the second transparent housing 20V. Preferably, the seal 50 is water - sealedly arranged between the lid 40 and the second opening portion 22V of the second transparent housing 20V. More preferably, the seal 50 of the housing for a water purifier according to the present invention is water - sealedly arranged between the lid 40 and the head 2202V of the second opening portion 22V of the second transparent housing 20V.

[0056] As shown in the attached drawings Figures 1A to 1D As shown, the lid 40 of the housing for a water purifier according to an embodiment of the present invention includes a lid body 41 and a screwing portion 42. The screwing portion 42 of the lid 40 extends from the periphery 4111 of the inner side 411 of the lid body 41. The seal 50 is arranged on the inner side 411 of the lid body 41. The second opening portion 22V of the second transparent housing 20V further has a first thread 23V. The screwing portion 42 of the lid 40 is arranged around the seal 50, and the screwing portion 42 forms a second thread 421. The second thread 421 is arranged to be screwed with the first thread 23V of the second opening portion 22V of the second transparent housing 20V, so that the lid 40 can be screwed to the second opening portion 22V of the second transparent housing 20V and the seal 50 can be pressed against the second opening portion 22V of the second transparent housing 20V and be water - sealedly arranged between the lid 40 and the second opening portion 22V of the second transparent housing 20V. Preferably, the seal 50 is annular.

[0057] As shown in the attached drawings Figures 1A to 1DAs shown, the first thread 23V of the housing for a water purifier according to an embodiment of the present invention is an external thread formed on the outer sidewall 221V of the second opening 22V of the second transparent housing 20V, and the second thread 421 of the screwing portion 42 of the lid 40 is an internal thread formed on the inner sidewall 422 of the screwing portion 42 of the lid 40, wherein the second thread 421 is arranged to be screwed together with the first thread 23V of the second opening 22V of the second transparent housing 20V, so that the seal 50 is hermetically arranged between the lid 40 and the second opening 22V of the second transparent housing 20V.

[0058] As shown in the attached drawings Figures 1A to 1D As shown, the second opening 22V of the second transparent housing 20V of the housing for a water purifier according to an embodiment of the present invention forms a top end 222V, a bottom end 223V, and a thread forming portion 224V extending between the top end 222V and the bottom end 223V. Among them, the top end 222V of the second opening 22V of the second transparent housing 20V forms the second opening 220V, the bottom end 223V of the second opening 22V of the second transparent housing 20V is covered by the first opening 12V of the first transparent housing 10V, and the first thread 23V of the second opening 22V of the second transparent housing 20V is formed on the thread forming portion 224V of the second opening 22V of the second transparent housing 20V. Correspondingly, the neck 2201V of the second opening 22V of the second transparent housing 20V of the housing for a water purifier of the present invention is formed at the bottom end 223V of the second opening 22V of the second transparent housing 20V.

[0059] It should be noted that the first transparent housing 10V and the second transparent housing 20V of the housing for a water purifier according to the embodiments of the present invention are made of different transparent materials. In particular, when the elongation at break of the material for manufacturing the second transparent housing 20V is greater than that of the material for manufacturing the first transparent housing 10V, the first transparent housing 10V and the second transparent housing 20V can form a complementary support structure, so as to have a better effect of resisting the water hammer formed by the raw water in the water treatment chamber 210V. Under the condition of the same thickness, the housing made of the material with a larger elongation at break (better flexibility) is prone to expand under the action of water hammer, while the housing made of the material with a smaller elongation at break (stronger rigidity) is prone to crack under the action of water hammer. The first transparent housing 10V and the second transparent housing 20V of the housing for a water purifier according to the present invention are made of materials with different elongation at breaks. In particular, when the elongation at break of the material for manufacturing the second transparent housing 20V is greater than that of the material for manufacturing the first transparent housing 10V, the support performance of the housing for a water purifier according to the present invention can be better than that of the housing for a water purifier with the same thickness but made of a single material with a smaller or larger elongation at break (for example, better water hammer resistance effect and longer service life). It can be understood that the threaded part of the housing for a water purifier according to the present invention is prone to crack under the action of water hammer. Therefore, the material of the second opening 22V of the second transparent housing 20V of the housing for a water purifier according to the present invention has a larger elongation at break, and the first thread 23V of the second opening 22V of the second transparent housing 20V of the housing for a water purifier according to the present invention is formed on the outer side of the second opening 22V of the second transparent housing 20V, so that the first thread 23V (or the thread forming part 224V) of the housing for a water purifier according to the present invention is not easy to crack. The second opening 22V of the second transparent housing 20V of the housing for a water purifier according to the embodiments of the present invention is connected to the lid 40 of the housing for a water purifier according to the embodiments of the present invention (for example, when they are screwed together), and the second opening 22V of the second transparent housing 20V protrudes outward from the first opening 120V of the first opening 12V of the first transparent housing 10V, so as to prevent the first main body part 11V and the first opening 12V of the first transparent housing 10V from cracking due to the stress generated by the connection between the lid 40 and the second transparent housing 20V.

[0060] As shown in the attached drawings Figures 1A to 1D Preferably, as shown, the head 2202V of the second opening 22V of the second transparent housing 20V of the housing for a water purifier according to the embodiments of the present invention is thickened to strengthen its strength and prevent it from cracking when subjected to stress.

[0061] Furthermore, considering that the product formed by integrally molding only the first transparent housing 10V and the second transparent housing 20V of the housing for a water purifier according to the embodiments of the present invention can be used for sale purposes (the lid 40 can be configured by downstream distributors), therefore, although the present invention exemplarily describes the screwing connection between the second opening 22V of the second transparent housing 20V of the housing for a water purifier according to the embodiments of the present invention and the lid 40, the housing for a water purifier according to the embodiments of the present invention does not limit that it must have the lid 40 and the seal 50.

[0062] Correspondingly, the second transparent housing 20V and the first transparent housing 10V of the housing for a water purifier according to the embodiments of the present invention are integrally molded. Both the first transparent housing 10V and the second transparent housing 20V are made of a transparent material (resin material), and the first transparent housing 10V and the second transparent housing 20V have different light transmittances (different transparent materials often have different natural colors and light transmittances), so that the first transparent housing 10V and the second transparent housing 20V of the housing for a water purifier according to the embodiments of the present invention can form a complementary advantage and have a better anti-water hammer effect. In addition, although the first transparent housing 10V and the second transparent housing 20V have different light transmittances, the first transparent housing 10V and the second transparent housing 20V of the housing for a water purifier according to the present invention are made of materials with appropriate light transmittances, so that users can observe the usage situation of the water treatment materials in the water treatment chamber 210V through the first transparent housing 10V and the second transparent housing 20V and determine whether it is necessary to replace the water treatment materials.

[0063] As shown in the attached drawings Figure 9A and Figure 9BAs shown, preferably, the housing for a water purifier according to an embodiment of the present invention further includes a sealing sheet 70, wherein the sealing sheet 70 is disposed between the second bottom 2012V of the second transparent housing 20V and the first bottom 1012V of the first transparent housing 10V, and the sealing sheet 70 is disposed opposite to the injection hole forming portion 20121V of the second bottom 2012V of the second transparent housing 20V, or / and the sealing sheet 70 is disposed opposite to the injection hole forming portion 10121V of the first bottom 1012V of the first transparent housing 10V. It can be understood that both the first transparent housing 10V and the second transparent housing 20V of the housing for a water purifier according to an embodiment of the present invention are cylindrical structures. When injection molding, the molding resin needs to be injected from the bottom. When the first transparent housing 10V and the second transparent housing 20V are molded, the injection hole forming portion 10121V and the injection hole forming portion 20121V formed by the molding resin at the molding resin injection site may form holes due to air bubbles, resulting in water leakage. The sealing sheet 70 of the housing for a water purifier according to the present invention is disposed between the second bottom 2012V of the second transparent housing 20V and the first bottom 1012V of the first transparent housing 10V, and the sealing sheet 70 is disposed opposite to the injection hole forming portion 20121V of the second bottom 2012V of the second transparent housing 20V, or / and the sealing sheet 70 is disposed opposite to the injection hole forming portion 10121V of the first bottom 1012V of the first transparent housing 10V, which can form a seal at the injection hole forming portion 20121V of the second bottom 2012V of the second transparent housing 20V when the first transparent housing 10V and the second transparent housing 20V form an integral structure.

[0064] Among the accompanying drawings Figures 2A to 2DShown is an alternative embodiment of a housing for a water purifier according to an embodiment of the present invention, which includes a first transparent housing 10X and a second transparent housing 20X, wherein the first transparent housing 10X at least partially covers the outer surface 201X of the second transparent housing 20X, and the first transparent housing 10X and the second transparent housing 20X are integrally formed. The second transparent housing 20X forms a water treatment chamber 210X, and the first transparent housing 10X and the second transparent housing 20X have different light transmittances. It can be understood that the water treatment chamber 210X formed by the second transparent housing 20X of the housing for a water purifier according to an embodiment of the present invention is used to accommodate water treatment materials therein for purifying raw water entering the water treatment chamber 210X. Therefore, the second transparent housing 20X of the housing for a water purifier according to an embodiment of the present invention is vulnerable to the water hammer effect caused by the change in the water pressure of the raw water (or tap water). Preferably, the flexibility (or rigidity) of the first transparent housing 10X and the second transparent housing 20X of the housing for a water purifier according to an embodiment of the present invention is different, so that the first transparent housing 10X and the second transparent housing 20X can form a complementarity and can integrally provide better support for the raw water contained in the water treatment chamber 210X. In other words, the different flexibilities of the first transparent housing 10X and the second transparent housing 20X of the housing for a water purifier of the present invention can make the housing for a water purifier of the present invention as a whole provide better support for the raw water contained in the water treatment chamber 210X. More preferably, the flexibility of the second transparent housing 20X of the housing for a water purifier according to an embodiment of the present invention is better than that of the first transparent housing 10X. Most preferably, the elongation at break of the second transparent housing 20X of the housing for a water purifier according to an embodiment of the present invention is greater than the elongation at break of the first transparent housing 10X to ensure that the water pressure borne by the second transparent housing 20X can be better transmitted to the first transparent housing 10X and that the complementary effect formed by the first transparent housing 10X and the second transparent housing 20X can better counteract the water hammer formed by the raw water in the water treatment chamber 210X.

[0065] As shown in the attached drawing Figures 2A to 2DAs shown, the first transparent housing 10X of the optional embodiment of the housing for a water purifier according to an embodiment of the present invention includes a first main body portion 11X and a first opening portion 12X, and the second transparent housing 20X includes a second main body portion 21X and a second opening portion 22X. The first opening portion 12X of the first transparent housing 10X extends integrally from the first main body portion 11X, and the second opening portion 22X of the second transparent housing 20X extends integrally from the second main body portion 21X. The first opening portion 12X of the first transparent housing 10X forms a first opening 120X, and the second opening portion 22X of the second transparent housing 20X forms a second opening 220X. The first opening 120X of the first opening portion 12X of the first transparent housing 10X and the second opening 220X of the second opening portion 22X of the second transparent housing 20X face the same direction. The first main body portion 11X of the first transparent housing 10X integrally wraps around the second main body portion 21X of the second transparent housing 20X, and the first opening portion 12X of the first transparent housing 10X integrally wraps around the second opening portion 22X of the second transparent housing 20X. Accordingly, the first main body portion 11X of the first transparent housing 10X and the second main body portion 21X of the second transparent housing 20X are integrally formed, and the first opening portion 12X of the first transparent housing 10X and the second opening portion 22X of the second transparent housing 20X are integrally formed.

[0066] As shown in the attached drawings Figures 2A to 2D As shown, further, the longitudinal cross-sections of the first transparent housing 10X and the second transparent housing 20X of the optional embodiment of the housing for a water purifier according to an embodiment of the present invention are both "U" shaped, so that the first transparent housing 10X and the second transparent housing 20X can form a "U" shaped double-layer structure. Therefore, the longitudinal cross-sections of the first transparent housing 10X and the second transparent housing 20X of the optional embodiment of the housing for a water purifier according to an embodiment of the present invention are both "U" shaped, so that the longitudinal cross-section of the optional embodiment of the housing for a water purifier according to an embodiment of the present invention as a whole has a "U" shaped double-layer structure.

[0067] As shown in the attached drawings Figures 2A to 2D As shown, the optional embodiment of the housing for a water purifier according to an embodiment of the present invention further includes a lid 40E and a seal 50E, and the seal 50E is hermetically arranged between the lid 40E and the product formed by integrally molding the first transparent housing 10X and the second transparent housing 20X. Preferably, the seal 50E is hermetically arranged between the lid 40E and the second opening portion 22X of the second transparent housing 20X.

[0068] As shown in the attached drawings Figures 2A to 2DAs shown, the lid 40E of this alternative embodiment of the housing for a water purifier according to an embodiment of the present invention includes a lid body 41E and a screwing portion 42E. The screwing portion 42E of the lid 40E extends from the outer side 411E of the lid body 41E. The seal 50E is disposed between the screwing portion 42E of the lid 40E and the second opening 22X of the second transparent housing 20X. The second opening 22X of the second transparent housing 20X further has a first thread 23X, and the screwing portion 42E of the lid 40E forms a second thread 421E. The second thread 421E is arranged to be screwed together with the first thread 23X of the second opening 22X of the second transparent housing 20X, so that the lid 40E can be screwed to the second opening 22X of the second transparent housing 20X and the seal 50E is pressed against the second opening 22X of the second transparent housing 20X and is water-sealedly disposed between the screwing portion 42E of the lid 40E and the second opening 22X of the second transparent housing 20X. Preferably, the length of the first opening 12X of the first transparent housing 10X is not less than the length of the second opening 22X of the second transparent housing 20X, so that the second opening 22X of the second transparent housing 20X is completely covered by the first opening 12X of the first transparent housing 10X. Therefore, the lid 40E of the embodiment of the present invention and the second opening 22X of the second transparent housing 20X form a seal, so that the water pressure can only act in the sealed cavity formed by the lid 40E, the seal 50E and the second transparent housing 20X, avoiding the direct action of the water pressure and the water hammer generated by the water pressure on the first opening 12X of the first transparent housing 10X made of transparent material. The elongation at break of the second transparent housing 20X of the housing for a water purifier of the present invention is greater than the elongation at break of the first transparent housing 10X, and the anti-water hammer impact performance is stronger. The second opening 22X of the second transparent housing 20X is not easily broken under the action of the water pressure and the water hammer generated by the water pressure, thereby increasing the service life of the alternative embodiment of the housing for a water purifier of the embodiment of the present invention. Preferably, the seal 50E is annular.

[0069] As shown in the accompanying drawings Figures 2A to 2DAs shown, the first thread 23X of the optional implementation of the housing for a water purifier according to an embodiment of the present invention is an internal thread formed on the inner sidewall 221X of the second opening 22X of the second transparent housing 20X, and the second thread 421E of the screwing portion 42E of the lid 40E is an external thread formed on the outer sidewall 422E of the screwing portion 42E of the lid 40E, wherein the second thread 421E is arranged to be screwed together with the first thread 23X of the second opening 22X of the second transparent housing 20X, so that the seal 50E is hermetically arranged between the lid 40E and the second opening 22X of the second transparent housing 20X.

[0070] As shown in the attached drawings Figures 2A to 2D As shown, the second opening 22X of the second transparent housing 20X of the optional implementation of the housing for a water purifier according to an embodiment of the present invention forms a top end 222X, a bottom end 223X and a thread forming portion 224X extending between the top end 222X and the bottom end 223X, wherein the thread forming portion 224X of the second opening 22X of the second transparent housing 20X extends outward and upward from the bottom end 223X, the top end 222X of the second opening 22X of the second transparent housing 20X forms the second opening 220X, and the first thread 23X of the second opening 22X of the second transparent housing 20X is formed on the thread forming portion 224X of the second opening 22X of the second transparent housing 20X. As shown in the attached drawings Figures 2A to 2D As shown, preferably, the second opening 22X of the second transparent housing 20X is thickened to strengthen its strength, so as to prevent the second opening 22X of the second transparent housing 20X from being damaged or broken under the action of the stress generated by the connection (for example, screwing together) between the second opening 22X of the second transparent housing 20X and the lid 40E of the optional implementation of the housing for a water purifier according to an embodiment of the present invention. Preferably, the seal 50E is hermetically arranged between the lid 40E and the bottom end 223X of the second opening 22X of the second transparent housing 20X.

[0071] Furthermore, considering that the optional implementation of the housing for a water purifier according to an embodiment of the present invention only requires the fabricated article formed by integrally molding the first transparent housing 10X and the second transparent housing 20X to be available for sale purposes (the lid 40E can be configured by downstream distributors), therefore, although the present invention exemplarily describes the screwing connection between the second opening 22X of the second transparent housing 20X and the lid 40E of the optional implementation of the housing for a water purifier according to an embodiment of the present invention, the optional implementation of the housing for a water purifier according to an embodiment of the present invention does not limit that it must have the lid 40E and the seal 50E.

[0072] Correspondingly, in the optional implementation of the housing for a water purifier according to an embodiment of the present invention, the second transparent housing 20X and the first transparent housing 10X are integrally molded. Both the first transparent housing 10X and the second transparent housing 20X are made of transparent materials (resin materials). The first transparent housing 10X and the second transparent housing 20X have different light transmittances (different transparent materials often have different natural colors and light transmittances), and the elongation at break of the first transparent housing 10X and the second transparent housing 20X is different. As a result, the first transparent housing 10X and the second transparent housing 20X of the optional implementation of the housing for a water purifier according to an embodiment of the present invention play a complementary role in structure and make the integrated structure formed by the first transparent housing 10X and the second transparent housing 20X have better resistance to water hammer. In the case of the same thickness, the housing made of a material with a larger elongation at break (better flexibility) is prone to expansion under the action of water hammer, while the housing made of a material with a smaller elongation at break (stronger rigidity) is prone to cracking under the action of water hammer. The first transparent housing 10X and the second transparent housing 20X of the housing for a water purifier according to the present invention are made of materials with different elongations at break. Especially when the elongation at break of the manufacturing material of the second transparent housing 20X is greater than that of the manufacturing material of the first transparent housing 10X, the support performance of the housing for a water purifier according to the present invention can be better than that of the housing for a water purifier with the same thickness but made of a single material with a smaller or larger elongation at break (for example, better anti-water hammer effect and longer service life). In addition, although the first transparent housing 10X and the second transparent housing 20X have different light transmittances, the first transparent housing 10X and the second transparent housing 20X of the housing for a water purifier according to the present invention are made of materials with appropriate light transmittances, so that users can observe the usage situation of the water treatment materials in the water treatment chamber 210X through the first transparent housing 10X and the second transparent housing 20X and determine whether it is necessary to replace the water treatment materials.

[0073] As shown in the accompanying drawings Figure 10A and Figure 10BAs shown, preferably, this alternative embodiment of the housing for a water purifier according to an embodiment of the present invention further includes a sealing sheet 70, wherein the sealing sheet 70 is disposed between the second bottom 2012X of the second transparent housing 20X and the first bottom 1012X of the first transparent housing 10X, and the sealing sheet 70 is disposed opposite the injection hole forming portion 20121X of the second bottom 2012X of the second transparent housing 20X, or / and the sealing sheet 70 is disposed opposite the injection hole forming portion 10121X of the first bottom 1012X of the first transparent housing 10X. It can be understood that both the first transparent housing 10X and the second transparent housing 20X of the housing for a water purifier according to an embodiment of the present invention are cylindrical structures. When injection molding, the molding resin needs to be injected from the bottom. When the first transparent housing 10X and the second transparent housing 20X are molded, the injection hole forming portion 10121X and the injection hole forming portion 20121X formed by the molding resin at the molding resin injection site may form holes due to air bubbles, resulting in water leakage. The sealing sheet 70 of the housing for a water purifier of the present invention is disposed between the second bottom 2012X of the second transparent housing 20X and the first bottom 1012X of the first transparent housing 10X, and the sealing sheet 70 is disposed opposite the injection hole forming portion 20121X of the second bottom 2012X of the second transparent housing 20X, or / and the sealing sheet 70 is disposed opposite the injection hole forming portion 10121X of the first bottom 1012X of the first transparent housing 10X, and can form a seal at the injection hole forming portion 20121X of the second bottom 2012X of the second transparent housing 20X when the first transparent housing 10X and the second transparent housing 20X form an integral structure.

[0074] Among the drawings Figures 3A to 3DShown is another alternative embodiment of the housing for a water purifier according to an embodiment of the present invention, wherein the alternative embodiment of the housing for a water purifier according to an embodiment of the present invention includes a first transparent housing 10U and a second transparent housing 20U, wherein the first transparent housing 10U at least partially covers the outer surface 201U of the second transparent housing 20U, and the first transparent housing 10U and the second transparent housing 20U are integrally formed, wherein the second transparent housing 20U forms a water treatment chamber 210U, and the first transparent housing 10U and the second transparent housing 20U have different light transmittances. It can be understood that the water treatment chamber 210U formed by the second transparent housing 20U of the housing for a water purifier according to an embodiment of the present invention is used to accommodate water treatment materials therein for purifying the raw water entering the water treatment chamber 210U. Therefore, the second transparent housing 20U of the housing for a water purifier according to an embodiment of the present invention is vulnerable to the water hammer effect caused by the change in water pressure of the raw water (or tap water). Preferably, the flexibility (or rigidity) of the first transparent housing 10U and the second transparent housing 20U of the housing for a water purifier according to an embodiment of the present invention is different, so that the first transparent housing 10U and the second transparent housing 20U can form a complementarity and can integrally provide better support for the raw water contained in the water treatment chamber 210U. In other words, the different flexibilities of the first transparent housing 10U and the second transparent housing 20U of the housing for a water purifier of the present invention can make the housing for a water purifier of the present invention as a whole provide better support for the raw water contained in the water treatment chamber 210U. More preferably, the flexibility of the second transparent housing 20U of the housing for a water purifier according to an embodiment of the present invention is better than that of the first transparent housing 10U. Most preferably, the elongation at break of the second transparent housing 20U of the housing for a water purifier according to an embodiment of the present invention is greater than the elongation at break of the first transparent housing 10U, to ensure that the water pressure borne by the second transparent housing 20U can be better transmitted to the first transparent housing 10U and to enable the complementary effect formed by the first transparent housing 10U and the second transparent housing 20U to better resist the water hammer formed by the raw water in the water treatment chamber 210U.

[0075] As shown in the accompanying drawings Figures 3A to 3DAs shown, the first transparent housing 10U of the optional embodiment of the housing for a water purifier according to the embodiment of the present invention has a first main body portion 11U, a first opening portion 12U extending from the first main body portion 11U, and a first flanging 14U extending outward from the first opening portion 12U. The second transparent housing 20U has a second main body portion 21U, a second opening portion 22U extending from the second main body portion 21U, and a second flanging 24U extending outward from the second opening portion 22U. Wherein the first opening portion 12U of the first transparent housing 10U forms a first opening 120U, and the second opening portion 22U of the second transparent housing 20U forms a second opening 220U. Wherein the first opening 120U of the first opening portion 12U of the first transparent housing 10U and the second opening 220U of the second opening portion 22U of the second transparent housing 20U face the same direction. Wherein the first main body portion 11U and the first opening portion 12U of the first transparent housing 10U are both covered by the second main body portion 21U of the second transparent housing 20U, and the first flanging 14U of the first transparent housing 10U is integrally formed with the second flanging 24U of the second transparent housing 20U. Preferably, the first flanging 14U of the first transparent housing 10U and the second flanging 24U of the second transparent housing 20U of the housing for a water purifier according to the present invention are both annular.

[0076] It should be noted that, in this alternative embodiment of the housing for a water purifier according to the embodiments of the present invention, the first transparent housing 10U and the second transparent housing 20U are integrally formed. Both the first transparent housing 10U and the second transparent housing 20U are made of a transparent material (resin material). The first transparent housing 10U and the second transparent housing 20U have different light transmittances, and the elongation at break of the first transparent housing 10U and the second transparent housing 20U is different. In particular, when the elongation at break of the manufacturing material of the second transparent housing 20U is greater than that of the manufacturing material of the first transparent housing 10U, the first transparent housing 10U and the second transparent housing 20U can form a complementary support structure, so as to have a better effect of resisting the water hammer formed by the raw water in the water treatment chamber 210U. Under the condition of the same thickness, the housing made of a material with a larger elongation at break (better flexibility) is prone to expansion under the action of water hammer, while the housing made of a material with a smaller elongation at break (stronger rigidity) is prone to cracking under the action of water hammer. The first transparent housing 10U and the second transparent housing 20U of the housing for a water purifier according to the present invention are made of materials with different elongations at break. In particular, when the elongation at break of the manufacturing material of the second transparent housing 20U is greater than that of the manufacturing material of the first transparent housing 10U, the support performance of the housing for a water purifier according to the present invention can be better than that of the housing for a water purifier with the same thickness but made of a single material with a smaller or larger elongation at break (for example, better water hammer resistance effect and longer service life).

[0077] As shown in the accompanying drawings Figures 3A to 3D As shown, this alternative embodiment of the housing for a water purifier according to the embodiments of the present invention further includes a connector 60. The connector 60 includes a socket part 61, a thread forming part 62 extending upward from the socket part 61, and a connecting part 63 extending downward and inward from the socket part 61. The thread forming part 62 forms a first thread 601, the connecting part 63 forms a socket opening 630, and the inner diameter of the socket opening 630 is smaller than the outer diameters of the first flange 14U of the first transparent housing 10U and the second flange 24U of the second transparent housing 20U, so that both the first flange 14U of the first transparent housing 10U and the second flange 24U of the second transparent housing 20U can be sleeved on the inner side wall 611 of the socket part 61, and the connecting part 63 of the connector 60 can press against the bottom 142U of the first flange 14U of the first transparent housing 10U. Preferably, the first thread 601 of the connector 60 is formed on the inner side wall 621 of the thread forming part 62 of the connector 60. More preferably, the connector 60 is in a cylindrical shape. It can be understood that the connecting part 63 of the connector 60 of the housing for a water purifier according to the present invention ensures the sleeved connection between the connector 60 and the first transparent housing 10U.

[0078] As shown in the accompanying drawings Figures 3A to 3D shown, this alternative embodiment of the housing for a water purifier according to an embodiment of the present invention further includes a lid 40U and a seal 50U, wherein the seal 50U is disposed in a water-tight manner between the lid 40U and the structure formed integrally by the first transparent housing 10U and the second transparent housing 20U. Preferably, the seal 50U is disposed in a water-tight manner between the lid 40U and the second hem 24U of the second transparent housing 20U.

[0079] As shown in the accompanying drawings Figures 3A to 3D shown, the lid 40U of this alternative embodiment of the housing for a water purifier according to an embodiment of the present invention includes a lid body 41U and a screwing portion 42U, wherein the screwing portion 42U of the lid 40U extends from the outer side 411U of the lid body 41U, the seal 50U is disposed between the screwing portion 42U of the lid 40U and the second hem 24U of the second transparent housing 20U, wherein the screwing portion 42U of the lid 40U forms a second thread 421U, wherein the second thread 421U is arranged to be screwed together with the first thread 601 of the connecting member 60, so that the lid 40U can be screwed to the connecting member 60 and the seal 50U is pressed against the second hem 24U of the second transparent housing 20U and disposed in a water-tight manner between the screwing portion 42U of the lid 40U and the second hem 24U of the second transparent housing 20U. Preferably, the seal 50U is annular, and the width of the seal 50U is not greater than the width of the second hem 24U of the second transparent housing 20U.

[0080] As shown in the accompanying drawings Figures 3A to 3DAs shown, in this alternative embodiment of the housing for a water purifier according to the embodiments of the present invention, the first thread 601 of the connector 60 is an internal thread formed on the inner sidewall 621 of the thread forming portion 62 of the connector 60, and the second thread 421U of the screwing portion 42U of the lid 40U is an external thread formed on the outer sidewall 422U of the screwing portion 42U of the lid 40U, wherein the second thread 421U is arranged to be screwed together with the first thread 601 of the connector 60, so that the seal 50U is water-tightly arranged between the lid 40U and the second hem 24U of the second transparent housing 20U. Accordingly, when the connector 60 is connected to (e.g., screwed together with) the lid 40U of this alternative embodiment of the housing for a water purifier according to the embodiments of the present invention, the seal 50U is water-tightly arranged between the screwing portion 42U of the lid 40U and the second hem 24U of the second transparent housing 20U. Therefore, the lid 40U and the second transparent housing 20U of this alternative embodiment of the housing for a water purifier according to the present invention form a seal, so that water is contained in the sealed cavity formed by the lid 40U, the seal 50U and the second transparent housing 20U, to reduce the possibility of leakage of the water to be treated and the purified water. Further, the connector 60 is connected to the lid 40U of this alternative embodiment of the housing for a water purifier according to the embodiments of the present invention, and the connecting portion 63 of the connector 60 presses against the bottom 142U of the first hem 14U of the first transparent housing 10U, so that the magnitude of the stress generated by the connection between the connector 60 and the lid 40U on the second main body portion 21U and the second opening portion 22U of the second transparent housing 20U is greatly reduced, to avoid excessive stress on them. It can be understood that the first hem 14U of the first transparent housing 10U and the second hem 24U of the second transparent housing 20U are further thickened and widened to further reduce the probability of cracking due to stress.

[0081] Further, considering that this alternative embodiment of the housing for a water purifier according to the embodiments of the present invention only requires a manufactured product formed by integrally molding the first transparent housing 10U and the second transparent housing 20U to be available for sale purposes (the lid 40U can be configured by downstream distributors), therefore, although the present invention exemplarily describes the screwing connection between the connector 60 and the lid 40U of this alternative embodiment of the housing for a water purifier according to the embodiments of the present invention, this alternative embodiment of the housing for a water purifier according to the embodiments of the present invention does not limit that it must have the lid 40U and the seal 50U.

[0082] Correspondingly, the second transparent housing 20U and the first transparent housing 10U of the optional embodiment of the housing for a water purifier according to the embodiments of the present invention are integrally formed. Both the first transparent housing 10U and the second transparent housing 20U are made of a transparent material (resin material), and the first transparent housing 10U and the second transparent housing 20U have different light transmittances (different transparent materials often have different natural colors and light transmittances), so that the first transparent housing 10U and the second transparent housing 20U of the housing for a water purifier according to the embodiments of the present invention can form a complementary effect and have a better anti-water hammer effect. In addition, although the first transparent housing 10U and the second transparent housing 20U have different light transmittances, the first transparent housing 10U and the second transparent housing 20U of the housing for a water purifier of the present invention are made of materials with appropriate light transmittances, so that the user can observe the usage of the water treatment material in the water treatment chamber 210U through the first transparent housing 10U and the second transparent housing 20U and determine whether it is necessary to replace the water treatment material.

[0083] As shown in the accompanying drawings Figure 11A and Figure 11BAs shown, preferably, this alternative embodiment of the housing for a water purifier according to an embodiment of the present invention further includes a sealing sheet 70, wherein the sealing sheet 70 is disposed between the second bottom 2012U of the second transparent housing 20U and the first bottom 1012U of the first transparent housing 10U, and the sealing sheet 70 is disposed opposite the injection hole forming portion 20121U of the second bottom 2012U of the second transparent housing 20U, or / and the sealing sheet 70 is disposed opposite the injection hole forming portion 10121U of the first bottom 1012U of the first transparent housing 10U. It can be understood that both the first transparent housing 10U and the second transparent housing 20U of the housing for a water purifier according to an embodiment of the present invention are cylindrical structures. When injection molding, the molding resin needs to be injected from the bottom. When the first transparent housing 10U and the second transparent housing 20U are molded, the injection hole forming portion 10121U and the injection hole forming portion 20121U formed by the molding resin at the molding resin injection site may form holes due to air bubbles, resulting in water leakage. The sealing sheet 70 of the housing for a water purifier of the present invention is disposed between the second bottom 2012U of the second transparent housing 20U and the first bottom 1012U of the first transparent housing 10U, and the sealing sheet 70 is disposed opposite the injection hole forming portion 20121U of the second bottom 2012U of the second transparent housing 20U, or / and the sealing sheet 70 is disposed opposite the injection hole forming portion 10121U of the first bottom 1012U of the first transparent housing 10U, and can form a seal at the injection hole forming portion 20121U of the second bottom 2012U of the second transparent housing 20U when the first transparent housing 10U and the second transparent housing 20U form an integral structure.

[0084] Among the drawings Figure 4A and Figure 4BShown is another alternative embodiment of the housing for a water purifier according to an embodiment of the present invention. The alternative embodiment of the housing for a water purifier according to an embodiment of the present invention includes a first transparent housing 10Y and a second transparent housing 20Y. The first transparent housing 10Y at least partially covers the outer surface 201Y of the second transparent housing 20Y, and the first transparent housing 10Y and the second transparent housing 20Y are integrally formed. The second transparent housing 20Y forms a water treatment chamber 210Y, and the first transparent housing 10Y and the second transparent housing 20Y have different light transmittances. It can be understood that the water treatment chamber 210Y formed by the second transparent housing 20Y of the housing for a water purifier according to an embodiment of the present invention is used to accommodate water treatment materials therein for purifying the raw water entering the water treatment chamber 210Y. Therefore, the second transparent housing 20Y of the housing for a water purifier according to an embodiment of the present invention is vulnerable to the water hammer effect caused by the change in the water pressure of the raw water (or tap water). Preferably, the flexibility (or rigidity) of the first transparent housing 10Y and the second transparent housing 20Y of the housing for a water purifier according to an embodiment of the present invention is different, so that the first transparent housing 10Y and the second transparent housing 20Y can form a complementarity and can integrally provide better support for the raw water contained in the water treatment chamber 210Y. In other words, the different flexibilities of the first transparent housing 10Y and the second transparent housing 20Y of the housing for a water purifier of the present invention can make the housing for a water purifier of the present invention as a whole provide better support for the raw water contained in the water treatment chamber 210Y. More preferably, the flexibility of the second transparent housing 20Y of the housing for a water purifier according to an embodiment of the present invention is better than that of the first transparent housing 10Y. Most preferably, the elongation at break of the second transparent housing 20Y of the housing for a water purifier according to an embodiment of the present invention is greater than the elongation at break of the first transparent housing 10Y to ensure that the water pressure borne by the second transparent housing 20Y can be better transmitted to the first transparent housing 10Y and that the complementary effect formed by the first transparent housing 10Y and the second transparent housing 20Y can better resist the water hammer formed by the raw water in the water treatment chamber 210Y.

[0085] As shown in the accompanying drawings Figure 4A and Figure 4BAs shown, the first transparent housing 10Y of this alternative embodiment of the housing for a water purifier according to an embodiment of the present invention has a first main body portion 11Y and a first opening portion 12Y extending from the first main body portion 11Y. The second transparent housing 20Y has a second main body portion 21Y, a second opening portion 22Y extending from the second main body portion 21Y, and a flange 24Y extending outward from the second opening portion 22Y. Wherein the first opening portion 12Y of the first transparent housing 10Y forms a first opening 120Y, and the second opening portion 22Y of the second transparent housing 20Y forms a second opening 220Y. Wherein the first opening 120Y of the first opening portion 12Y of the first transparent housing 10Y and the second opening 220Y of the second opening portion 22Y of the second transparent housing 20Y face the same direction. Wherein the first main body portion 11Y and the first opening portion 12Y of the first transparent housing 10Y are both covered by the second main body portion 21Y of the second transparent housing 20Y. Preferably, the flange 24Y of the second transparent housing 20Y is annular.

[0086] It should be noted that the first transparent housing 10Y and the second transparent housing 20Y of this alternative embodiment of the housing for a water purifier according to an embodiment of the present invention are integrally formed. The first transparent housing 10Y and the second transparent housing 20Y are both made of a transparent material (resin material). Wherein the first transparent housing 10Y and the second transparent housing 20Y have different light transmittances, and the elongation at break of the first transparent housing 10Y and the second transparent housing 20Y is different. Especially when the elongation at break of the manufacturing material of the second transparent housing 20Y is greater than that of the manufacturing material of the first transparent housing 10Y, the first transparent housing 10Y and the second transparent housing 20Y can form a complementary support effect in structure to have a better effect of resisting the water hammer formed by the raw water in the water treatment chamber 210Y. In the case of the same thickness, the housing made of a material with a larger elongation at break (better flexibility) is prone to expansion under the action of water hammer, while the housing made of a material with a smaller elongation at break (stronger rigidity) is prone to cracking under the action of water hammer. The first transparent housing 10Y and the second transparent housing 20Y of the housing for a water purifier of the present invention are made of materials with different elongations at break. Especially when the elongation at break of the manufacturing material of the second transparent housing 20Y is greater than that of the manufacturing material of the first transparent housing 10Y, the support performance of the housing for a water purifier of the present invention can be better than that of the housing for a water purifier made of a single material with a smaller or larger elongation at break but with the same thickness (for example, better anti-water hammer effect and longer service life). For example, in the case of the same thickness, the complementary support effect generated by the two is better than the support performance of the housing for a water purifier made of only the manufacturing material of the first transparent housing 10Y or the manufacturing material of the second transparent housing 20Y (greater anti-pressure and longer service life).

[0087] As shown in the accompanying drawings Figure 4A and Figure 4B shown, this alternative embodiment of the housing for a water purifier according to an embodiment of the present invention further includes a connecting member 60, wherein the connecting member 60 includes a socket portion 61, a thread forming portion 62 extending upward from the socket portion 61, and a connecting portion 63 extending downward and inward from the socket portion 61. The thread forming portion 62 forms a first thread 601, the connecting portion 63 forms a socket opening 630, and the inner diameter of the socket opening 630 is smaller than the outer diameter of the flange 24Y of the second transparent housing 20Y, so that the flange 24Y of the second transparent housing 20Y can be sleeved on the inner side wall 611 of the socket portion 61, and the connecting portion 63 of the connecting member 60 can press against the bottom 242Y of the flange 24Y of the second transparent housing 20Y. Preferably, the first thread 601 of the connecting member 60 is formed on the inner side wall 621 of the thread forming portion 62 of the connecting member 60. It can be understood that the connecting portion 63 of the connecting member 60 for the housing of the water purifier according to the present invention ensures the sleeved connection between the connecting member 60 and the second transparent housing 20Y. More preferably, the connecting member 60 is cylindrical.

[0088] As shown in the accompanying drawings Figure 4A and Figure 4B shown, this alternative embodiment of the housing for a water purifier according to an embodiment of the present invention further includes a lid 40U and a seal 50U, wherein the seal 50U is hermetically arranged between the lid 40U and the structure formed by integrally molding the first transparent housing 10Y and the second transparent housing 20Y. Preferably, the seal 50U is hermetically arranged between the lid 40U and the flange 24Y of the second transparent housing 20Y.

[0089] As shown in the accompanying drawings Figure 4A and Figure 4BAs shown, the lid 40U of this alternative embodiment of the housing for a water purifier according to an embodiment of the present invention includes a lid body 41U and a screwing portion 42U. The screwing portion 42U of the lid 40U extends from the outer side 411U of the lid body 41U. The seal 50U is disposed between the screwing portion 42U of the lid 40U and the flange 24Y of the second transparent housing 20Y. The screwing portion 42U of the lid 40U forms a second thread 421U. The second thread 421U is configured to be screwed together with the first thread 601 of the connecting member 60, so that the lid 40U can be screwed to the connecting member 60 and the seal 50U is pressed against the flange 24Y of the second transparent housing 20Y and is water-sealedly disposed between the screwing portion 42U of the lid 40U and the flange 24Y of the second transparent housing 20Y. Preferably, the seal 50U is annular, and the width of the seal 50U is not greater than the width of the flange 24Y of the second transparent housing 20Y.

[0090] As shown in the accompanying drawings Figure 4A and Figure 4BAs shown, for the optional implementation of the connector 60 of the housing for a water purifier according to an embodiment of the present invention, the first thread 601 is an internal thread formed on the inner sidewall 621 of the thread forming portion 62 of the connector 60, and the second thread 421U of the screwing portion 42U of the lid 40U is an external thread formed on the outer sidewall 422U of the screwing portion 42U of the lid 40U, wherein the second thread 421U is arranged to be screwed together with the first thread 601 of the connector 60, so that the seal 50U is water-tightly arranged between the lid 40U and the flange 24Y of the second transparent housing 20Y. Correspondingly, when the connector 60 is connected to (for example, screwed together with) the lid 40U of the optional implementation of the housing for a water purifier according to an embodiment of the present invention, the seal 50U is water-tightly arranged between the screwing portion 42U of the lid 40U and the flange 24Y of the second transparent housing 20Y. Therefore, the lid 40U and the second transparent housing 20Y of the embodiment of the present invention form a seal, so that water is contained in the sealed cavity formed by the lid 40U, the seal 50U, the flange 24Y of the second transparent housing 20Y, and the second transparent housing 20Y, to reduce the possibility of leakage of the water to be treated and the purified water. Further, the connector 60 is connected to the lid 40U of the optional implementation of the housing for a water purifier according to an embodiment of the present invention, and the connecting portion 63 of the connector 60 presses against the bottom 242Y of the flange 24Y of the second transparent housing 20Y, so that the magnitude of the stress generated by the connection between the connector 60 and the lid 40U on the second main body portion 21Y and the second opening portion 22Y of the second transparent housing 20Y is greatly reduced, to avoid excessive stress on it. It can be understood that the flange 24Y of the second transparent housing 20Y can also be thickened and widened to further reduce the probability of cracking due to stress.

[0091] Furthermore, considering that the optional implementation of the housing for a water purifier according to an embodiment of the present invention only requires the product formed by integrally molding the first transparent housing 10Y and the second transparent housing 20Y to be available for sale purposes (the lid 40U can be configured by downstream distributors), therefore, although the present invention exemplarily describes the screwing connection between the connector 60 and the lid 40U of the optional implementation of the housing for a water purifier according to an embodiment of the present invention, the optional implementation of the housing for a water purifier according to an embodiment of the present invention does not limit that it must have the lid 40U and the seal 50U.

[0092] Accordingly, the second transparent housing 20Y and the first transparent housing 10Y of the optional embodiment of the housing for a water purifier according to the embodiment of the present invention are integrally formed. Both the first transparent housing 10Y and the second transparent housing 20Y are made of a transparent material (resin material), and the first transparent housing 10Y and the second transparent housing 20Y have different light transmittances (different transparent materials often have different natural colors and light transmittances), so that the first transparent housing 10Y and the second transparent housing 20Y of the optional embodiment of the housing for a water purifier according to the embodiment of the present invention can form a complementary advantage and have a better anti-water hammer effect. In the case of the same thickness, the housing made of a material with a larger elongation at break (better flexibility) is prone to expansion under the action of water hammer, while the housing made of a material with a smaller elongation at break (stronger rigidity) is prone to cracking under the action of water hammer. The first transparent housing 10Y and the second transparent housing 20Y of the housing for a water purifier according to the present invention are made of materials with different elongation at breaks. Especially when the elongation at break of the manufacturing material of the second transparent housing 20Y is greater than that of the manufacturing material of the first transparent housing 10Y, the support performance of the housing for a water purifier according to the present invention can be better than that of the housing for a water purifier with the same thickness but made of a single material with a smaller or larger elongation at break (for example, better anti-water hammer effect and longer service life). In addition, although the first transparent housing 10Y and the second transparent housing 20Y have different light transmittances, the first transparent housing 10Y and the second transparent housing 20Y of the optional embodiment of the housing for a water purifier according to the present invention are made of materials with appropriate light transmittances, so that the user can observe the usage condition of the water treatment material in the water treatment chamber 210Y through the first transparent housing 10Y and the second transparent housing 20Y and judge whether it is necessary to replace the water treatment material.

[0093] It should be noted that, in order to reduce the manufacturing process difficulty of the optional implementation of the housing for the water purifier in the embodiments of the present invention while ensuring the safety of the optional implementation of the housing for the water purifier in the embodiments of the present invention, the thickness of the first transparent housing 10V (or the first transparent housing 10X, the first transparent housing 10U, or the first transparent housing 10Y) of the optional implementation of the housing for the water purifier in the embodiments of the present invention is not less than 2.5 mm, and the thickness of the second transparent housing 20V (or the second transparent housing 20X, the second transparent housing 20U, or the second transparent housing 20Y) is not less than 2.5 mm. The thickness ratio of the first transparent housing 10V (or the first transparent housing 10X, the first transparent housing 10U, or the first transparent housing 10Y) to the second transparent housing 20V (or the second transparent housing 20X, the second transparent housing 20U, or the second transparent housing 20Y) of the optional implementation of the housing for the water purifier in the embodiments of the present invention is 1:3 to 3:1. Preferably, the thickness ratio of the first transparent housing 10V (or the first transparent housing 10X, the first transparent housing 10U, or the first transparent housing 10Y) to the second transparent housing 20V (or the second transparent housing 20X, the second transparent housing 20U, or the second transparent housing 20Y) of the optional implementation of the housing for the water purifier in the embodiments of the present invention is 1:2 to 2:1.

[0094] As shown in the attached drawings Figure 12A and Figure 12BAs shown, preferably, this alternative embodiment of the housing for a water purifier according to an embodiment of the present invention further includes a sealing sheet 70, wherein the sealing sheet 70 is disposed between the second bottom 2012Y of the second transparent housing 20Y and the first bottom 1012Y of the first transparent housing 10Y, and the sealing sheet 70 is disposed opposite the injection hole forming portion 20121Y of the second bottom 2012Y of the second transparent housing 20Y, or / and the sealing sheet 70 is disposed opposite the injection hole forming portion 10121Y of the first bottom 1012Y of the first transparent housing 10Y. It can be understood that both the first transparent housing 10Y and the second transparent housing 20Y of the housing for a water purifier according to an embodiment of the present invention are cylindrical structures. When injection molding, the molding resin needs to be injected from the bottom. When the first transparent housing 10Y and the second transparent housing 20Y are molded, the injection hole forming portion 10121Y and the injection hole forming portion 20121Y formed by the molding resin at the molding resin injection site may form holes due to air bubbles, resulting in water leakage. The sealing sheet 70 of the housing for a water purifier of the present invention is disposed between the second bottom 2012Y of the second transparent housing 20Y and the first bottom 1012Y of the first transparent housing 10Y, and the sealing sheet 70 is disposed opposite the injection hole forming portion 20121Y of the second bottom 2012Y of the second transparent housing 20Y, or / and the sealing sheet 70 is disposed opposite the injection hole forming portion 10121Y of the first bottom 1012Y of the first transparent housing 10Y, which can form a seal at the injection hole forming portion 20121Y of the second bottom 2012Y of the second transparent housing 20Y when the first transparent housing 10Y and the second transparent housing 20Y form an integral structure.

[0095] Referring to the accompanying drawings of the specification Figures 5 to 7 , a method for manufacturing a housing for a water purifier is illustrated, which is applicable to manufacturing the housing for a water purifier according to an embodiment of the present invention.

[0096] Exemplarily, the method for manufacturing a housing for a water purifier of the present invention will be described below in conjunction with the second transparent housing 20V and the first transparent housing 10V of the housing for a water purifier according to an embodiment of the present invention.

[0097] The method for manufacturing the housing of a water purifier according to the present invention includes the following steps: (a) manufacturing the second transparent housing 20V by a hot injection molding process, and after the second transparent housing 20V is molded, opening the mold to take out the molded second transparent housing 20V, and then cooling the second transparent housing 20V to a first preset temperature; (b) manufacturing the first transparent housing 10V by a hot injection molding process, and after the first transparent housing 10V is molded, opening the mold to take out the molded first transparent housing 10V, and then cooling the first transparent housing 10V to a second preset temperature; (c) placing the molded second transparent housing 20V into the cavity 101V of the molded first transparent housing 10V; (d) making the second cylinder 2011V of the second transparent housing 20V with the first preset temperature be at a first preset distance from the first cylinder 1011V of the first transparent housing 10V with the second preset temperature, and making the second bottom 2012V of the second transparent housing 20V with the first preset temperature be at a second preset distance from the first bottom 1012V of the first transparent housing 10V with the second preset temperature, so that the first transparent housing 10V and the second transparent housing 20V form a nested structure; and (e) cooling the nested structure to room temperature, so that the first transparent housing 10V can cover the second transparent housing 20V. Preferably, the second preset temperature is higher than the first preset temperature. More preferably, the second preset temperature is not lower than 60 degrees Celsius (60°C) and not higher than 150 degrees Celsius (150°C), and the first preset temperature is room temperature of 10 - 35 degrees Celsius (10 - 35°C). It can be understood that the inner diameter of the cavity 101V of the first transparent housing 10V with the second preset temperature is slightly larger than the outer diameter of the second transparent housing 20V with the first preset temperature, wherein the second transparent housing 20V forms a water treatment chamber 210V. Preferably, the first connecting portion 1013V of the first transparent housing 10V for the housing of the water purifier according to the present invention integrally and arc-shapedly extends between the first cylinder 1011V and the first bottom 1012V of the first transparent housing 10V, and the second connecting portion 2013V of the second transparent housing 20V for the housing of the water purifier according to the present invention integrally and arc-shapedly extends between the second cylinder 2011V and the second bottom 2012V of the second transparent housing 20V. It can be understood that the first connecting portion 1013V of the first transparent housing 10V for the housing of the water purifier according to the present invention integrally and arc-shapedly extends between the first cylinder 1011V and the first bottom 1012V and the cylindrical structure of the first cylinder 1011V of the first transparent housing 10V can ensure that the first transparent housing 10V for the housing of the water purifier contracts inward when the temperature decreases.Preferably, the thickness of the first bottom 1012V of the first transparent housing 10V of the water purifier according to the present invention is greater than the thickness of the first cylindrical body 1011V of the first transparent housing 10V, the thickness of the second bottom 2012V of the second transparent housing 20V is greater than the thickness of the second cylindrical body 2011V of the second transparent housing 20V, and the second preset distance is greater than the first preset distance. More preferably, according to the thickness of the first cylindrical body 1011V of the first transparent housing 10V of the water purifier according to the present invention, the size of the thickness of the first bottom 1012V of the first transparent housing 10V, the size of the inner and outer diameters of the first cylindrical body 1011V of the first transparent housing 10V, and the height of the first transparent housing 10V, the first preset distance is 0.15 - 2 mm, and the second preset distance is 0.8 - 10 mm, to ensure that after the first transparent housing 10V of the water purifier according to the present invention cools and shrinks, it tightly wraps around the outer surface of the second transparent housing 20V. Correspondingly, the first transparent housing 10V of the water purifier according to the present invention includes the first connecting portion 1013V, the first cylindrical body 1011V, and the first bottom 1012V, and the second transparent housing 20V of the water purifier according to the present invention includes the second connecting portion 2013V, the second cylindrical body 2011V, and the second bottom 2012V, and the first connecting portion 1013V, the first cylindrical body 1011V, and the first bottom 1012V are integrally formed, and the second connecting portion 2013V, the second cylindrical body 2011V, and the second bottom 2012V are integrally formed. Correspondingly, the first connecting portion 1013V, the first cylindrical body 1011V, and the first bottom 1012V of the first transparent housing 10V of the water purifier according to the present invention form the first main body portion 11V of the first transparent housing 10V, and the second transparent housing 20V of the water purifier according to the present invention includes the second connecting portion 2013V, the second cylindrical body 2011V, and the second bottom 2012V to form the second main body portion 21V of the second transparent housing 20V. It can be understood that the shape and size of the outer wall of the second main body portion 21V of the second transparent housing 20V having the first preset temperature of the water purifier housing according to the present invention are set to be adapted to the shape and size of the inner wall of the first main body portion 11V of the first transparent housing 10V having the second preset temperature of the water purifier housing according to the present invention, to ensure that the inner wall of the first transparent housing 10V of the water purifier housing according to the present invention after cooling can closely adhere to the outer wall of the second main body portion 21V of the second transparent housing 20V of the water purifier housing according to the present invention.

[0098] As shown in the attached drawings Figures 5 to 7As shown, exemplarily, the first transparent housing 10V for the water purifier according to an embodiment of the present invention further has a first opening 12V extending outward from the first main body portion 11V. The second transparent housing 20V further has a second opening 22V extending outward from the second main body portion 21V. Wherein, the second opening 22V of the second transparent housing 20V is provided with at least one support protrusion 2211V. When the nested structure formed by the first transparent housing 10V and the second transparent housing 20V is placed vertically, and the second opening 22V of the second transparent housing 20V and the first opening 12V of the first transparent housing 10V are arranged facing downward, the first transparent housing 10V can be supported by the second transparent housing 20V, so that the distance between the second cylinder 2011V of the second transparent housing 20V having the first preset temperature and the first cylinder 1011V of the first transparent housing 10V having the second preset temperature is maintained as the first preset distance, and the distance between the second bottom 2012V of the second transparent housing 20V having the first preset temperature and the first bottom 1012V of the first transparent housing 10V having the second preset temperature is maintained as the second preset distance. For example, as shown in the accompanying drawings Figures 1A to 1D As shown, the second opening 22V of the second transparent housing 20V of the housing for the water purifier according to the present invention is thickened so that the first opening 12V of the first transparent housing 10V can be supported on the second opening 22V of the second transparent housing 20V; as shown in the accompanying drawings Figures 2A to 2D As shown, the second opening 22X of the second transparent housing 20X of the housing for the water purifier according to the present invention is thickened so that the second opening 22X of the second transparent housing 20X of the housing for the water purifier according to the present invention is thickened so that the first opening 12X of the first transparent housing 10X can be supported on the second opening 22X of the second transparent housing 20X; as shown in the accompanying drawings Figures 3A to 3D As shown, the first hem 14U of the first transparent housing 10U and the second hem 24U of the second transparent housing 20U of the housing for the water purifier according to the present invention at least partially overlap, so that the first opening 12U and the first hem 14U of the first transparent housing 10U can be supported on the second hem 24U of the second transparent housing 20U; as shown in the accompanying drawings Figure 4A and Figure 4B As shown, the second transparent housing 20Y of the housing for the water purifier according to the present invention has the hem 24Y so that the first opening 12Y of the first transparent housing 10Y can be supported on the hem 24Y of the second transparent housing 20Y. Therefore, as shown in the accompanying drawings Figures 1A to 1D As shown, the second opening 22V of the second transparent housing 20V of the housing for the water purifier according to the present invention forms the support protrusion 2211V; as shown in the accompanying drawingsFigures 2A to 2D As shown, a support protrusion 2211X is formed at the second opening 22X of the second transparent housing 20X of the housing for a water purifier according to the present invention; as shown in the accompanying drawings Figures 3A to 3D As shown, a support protrusion 2211U is formed at the second hem 24U of the second transparent housing 20U of the housing for a water purifier according to the present invention; as shown in the accompanying drawings Figure 4A and Figure 4B As shown, a support protrusion 2211Y is formed at the hem 24Y of the second transparent housing 20Y of the housing for a water purifier according to the present invention.

[0099] As shown in the accompanying drawings Figure 8 As shown, exemplarily, the nested structure formed by the first transparent housing 10V and the second transparent housing 20V of the housing for a water purifier according to an embodiment of the present invention can be placed in the molding cavity 81 of a mold 80 for molding. At this time, an elastic support structure is provided between the mold 80 and the first bottom 1012V of the first transparent housing 10V, and a limiting member 82 is provided at the top of the mold 80. The limiting member 82 of the mold 80 is adapted to act on the second opening 22V of the second transparent housing 20V of the housing for a water purifier according to the present invention to ensure the positioning of the second transparent housing 20V of the housing for a water purifier according to the present invention. Correspondingly, under the action of the elastic support structure, the first transparent housing 10V of the housing for a water purifier according to an embodiment of the present invention is pushed against the second transparent housing 20V, so that the distance between the second cylinder 2011V of the second transparent housing 20V having the first preset temperature and the first cylinder 1011V of the first transparent housing 10V having the second preset temperature can be maintained as the first preset distance, and the distance between the second bottom 2012V of the second transparent housing 20V having the first preset temperature and the first bottom 1012V of the first transparent housing 10V having the second preset temperature can be maintained as the second preset distance. It can be understood that, as shown in the accompanying drawings Figure 8 As shown, when the nested structure formed by the first transparent housing 10V and the second transparent housing 20V of the housing for a water purifier according to an embodiment of the present invention is placed in the molding cavity 81 of the mold 80 for molding, the mold 80 can be placed vertically or horizontally. Correspondingly, the elastic support structure applies a first axial thrust to the first bottom 1012V of the first transparent housing 10V having the second preset temperature, and the limiting member 82 of the mold 80 applies a second axial thrust to the second opening 22V of the second transparent housing 20V having the first preset temperature, and the directions of the first axial thrust and the second axial thrust are opposite, so that the first transparent housing 10V is supported on the second transparent housing 20V.

[0100] Further, step (c) of the method for manufacturing the water purifier housing of the present invention includes the following steps:

[0101] (c1) Set the sealing sheet 70 at an appropriate position outside the second bottom 2012V of the second transparent housing 20V; and
