[0023] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.

[0024] This specific implementation provides a water purifier filter element and its detachable housing, which solves the technical problem in the prior art that the body of the housing and the top cover are prone to rotation, resulting in inconvenience in removing the housing.

[0025] Hereinafter, the embodiments will be described with reference to the drawings. In addition, the embodiments shown below do not limit the content of the utility model described in the claims in any way. In addition, all the contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the utility model described in the claims.

[0026] Referring to Figures 1-4 , the present utility model provides a detachable housing, including a top cover 1 and a first housing 2. The first housing 2 is provided with an opening, and the first housing 2 is detachably installed at the position of the opening, so that the top cover 1 and the first housing 2 enclose a first cavity for filtering water. In this way, the filter element for purifying water is installed in the first cavity, which is convenient for purifying water. In order to prevent the top cover 1 and the first housing 2 from rotating when removing the water purifier filter element in the water purifier, a first installation hole 11 is provided on the end surface of the first housing 2 where the opening is provided, and a second installation hole corresponding to the first installation hole 11 is provided on the top cover 1. The fastener is simultaneously inserted into the first installation hole 11 and the second installation hole. The fastener 4 limits the rotation between the first housing 2 and the top cover 1, thereby facilitating people to take out the housing from the inside of the water purifier, and avoiding the rotation between the top cover 1 and the first housing 2 in the prior art when removing the filter element.

[0027] As a further optimized solution, the connection between the top cover 1 and the first housing 2 is a threaded connection. Specifically, the top cover 1 is provided with a first threaded portion 12, and the first housing 2 is provided with a second threaded portion. The first threaded portion 12 is provided with a first protrusion 13 that can prevent rotation between the two. When the first housing 2 and the top cover 1 stop rotating, the first installation hole 11 and the second installation hole are aligned. In this way, it is convenient to align the first installation hole 11 and the second installation hole, avoiding people aligning the first installation hole 11 and the second installation hole when rotating, saving people's time. However, the components that can align the first installation hole 11 and the second installation hole are not limited to this type. It can also be that the top cover 1 is provided with a first marking line and the first housing is provided with a second marking line. When the first marking line and the second marking line are aligned, the first installation hole 11 and the second installation hole are aligned.

[0028] For a further optimized solution, in the prior art, generally the first housing is set as an integral structure, which is very inconvenient for people during processing. At the same time, after the first housing 2 is processed, the number of water inlets and outlets on the first housing is determined and cannot be changed. To change this situation, for a further optimized solution, the first housing 2 includes a bottom cover 22 and an annular housing body 21. Both ends of the housing body 21 are provided with openings. A top cover 1 is provided at the opening at the first end of the housing body 21, and a bottom cover 22 is provided at the opening at the second end. At least a first water inlet 221, a second water inlet 223, a first water outlet 222, and a second water outlet 224 are provided on the bottom cover 22. The first water inlet 221 is used to communicate with a water source, the first water outlet 222 is used to communicate with the second water inlet 223, and the second water outlet 224 is used to communicate with a water-using end. By separating the bottom shell from the housing body 21, people can separately process the annular cylinder and the bottom shell, which improves the processing speed, reduces the defective rate, saves people's processing time. At the same time, when people assemble, they can also replace the bottom cover 22 according to needs, not limited to only one type of outer shell.

[0029] For a further optimized solution, in order to facilitate the connection between the bottom cover and the housing of the water purifier, clamping ears 23 are provided on both sides of the bottom cover 22. The clamping ears 23 include a horizontal section 231 and a vertical section 232. One end of the horizontal section 231 is connected to one end of the vertical section 232. The clamping ears 23 are used to be clamped on the housing of the water purifier, and the side of the vertical section 232 away from the horizontal section 231 is set as a plane for fixing with a clamp. The number of the clamping ears 23 is at least two, which is convenient for keeping the outer shell balanced.

[0030] For a further optimized solution, in order to ensure the stability of the clamping ears 23, an annular stepped surface is provided on the outer peripheral surface of the bottom cover 22, and the other end of the vertical section 232 is connected to the stepped surface.

[0031] For a further optimized solution, in order to ensure the tightness of the connection between the top cover 1 and the housing body 21, a first sealing ring is provided between the top cover 1 and the housing body 21, and a first groove for installing the first sealing ring 5 is provided on the circumferential surface of the top cover 1.

[0032] This application document also provides a water purifier filter element, which includes the above-mentioned outer shell and also includes a core body 3. The core body 3 is installed in the outer shell, thus forming a water purifier filter element with a filtering function.

[0033] For a further optimized solution, the core body 3 includes a first filter body 31, a second filter body 32, and a partition plate 33. The partition plate 33 encloses a second cavity. The second filter body 32 is disposed in the second cavity and is in communication with the second water inlet 223 and the second water outlet 224. The inlet end of the first filter body 31 is in communication with the first water inlet 221, and the outlet end of the first filter body 31 is in communication with the first water outlet 222. The water filtered by the first filter body 31 enters the second filter body 32 through the first water outlet 222 and the second water inlet 223. By providing two types of filtration within one core body, the purity of the water filtration is ensured.

[0034] For a further optimized solution, to facilitate the second cavity to receive and convey water, a double-layer annular sleeve 34 is designed at one end of the partition plate 33 away from the top cover of the second cavity. The outer layer of the double-layer annular sleeve 34 is in communication with the second water inlet 223, and the inner layer of the double-layer annular sleeve 34 is in communication with the second water outlet 224. At the position where the double-layer annular sleeve 34 is connected to the partition plate 33, a second sealing ring 6 and a third sealing ring 7 are provided. The first filter body 31 is wrapped outside the double-layer annular sleeve 34. That is, the water enters the housing through the first water inlet 221, is filtered by the first filter body 31, and is discharged outward through the first water outlet 222. Then, it enters the second filter body 32 through the second water inlet 223 and the outer layer of the double-layer annular sleeve 34. After being filtered by the second filter body 32, the water is discharged from the position of the second water outlet 224 through the inner layer of the double-layer annular sleeve 34. With such a setting, two-stage filtration is carried out to ensure the water filtration effect.

[0035] For a further optimized solution, the first filter body 31 includes a carbon fiber filter element and a polypropylene filter element arranged from the inside out. The carbon fiber filter element is a composite depth filter composed of cellulose and activated carbon powder, combining the dual functions of cellulose and activated carbon adsorption. The outer layer of the middle column of the filter element is coated with a precision fiber filter material as a lining, and is supplemented by an activated carbon fiber cloth wound into shape. When the liquid flows through the filter material, the outer layer of the depth fiber filter material structure can block pollution particles, and the activated carbon in the filter cloth can remove odors, stinks, sediments, pigments, volatile organic compounds (VOCs), and organic chemical substances in the filtrate. The polypropylene filter element is made of polypropylene particles melted and sprayed into fine fibers and tightly wound into a white tubular filter element. It is non-toxic, and the fibers will not fall off during filtration, and it also maintains good air permeability. The second filter body 32 is provided with a carbon rod filter element, also known as a sintered activated carbon filter element or a CTO filter element. The carbon rod filter element has excellent adsorption performance of granular activated carbon and the precision filtration characteristics of a tubular element, and can effectively remove organic substances, particles, rust, residual chlorine, odors, etc. in the liquid.
