Description

Technical Field

[0001] The utility model belongs to the technical field of filtering devices, and particularly relates to a capsule filter and a water supply device. Background Art

[0002] A filter refers to a component used to filter impurities in a liquid. When the liquid flows through the filter, the filter medium of the filter intercepts the impurities in the liquid, and the purified and clean liquid flows out through the filter. Among them, an adsorption filter mainly uses the adsorption performance of the adsorption material to remove dissolved organic matter, residual chlorine, peculiar smell, etc. in the liquid.

[0003] In the related art, the adsorption filter includes a filter tube, an inlet hole and an outlet hole are formed on the filter tube, and a filter element is filled in the filter tube. The filter element is usually an adsorbent material such as activated carbon, etc. When the adsorption filter filters the liquid, the liquid enters the filter tube through the inlet hole, and the liquid removes the dissolved impurities in the liquid through the filter element, or physically intercepts the particulate matter in the liquid through a physical barrier, and the liquid is filtered and purified, and the purified liquid flows out through the outlet hole.

[0004] However, after the adsorption filter is used for a period of time, impurities will gradually accumulate on the filter element, thereby affecting the filtering effect. It is difficult to clean or replace the filter element of the existing adsorption filter. When the adsorption filter is replaced as a whole, the use cost increases. Summary of the Utility Model

[0005] In order to solve the deficiencies of the above-mentioned prior art, the utility model provides a capsule filter and a water supply device. The filter element can be inserted into the soft shell through the water inlet hole and fixed in the soft shell by a bone strip. The filter element is convenient for timely cleaning and replacement, and the capsule filter does not need to be replaced as a whole, which is convenient to use; in addition, in terms of the replacement frequency of the filter element and its cost control, compared with the traditional filter element with a larger volume, the impurity interception area of the traditional filter element is much smaller than that of the capsule filter element with the same volume after being divided into small parts, so that the replacement cost is greatly reduced.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. The described embodiments are some, but not all, of the embodiments of the present utility model.

[0031] Accordingly, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts fall within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] Please refer to the attached Figure 1-4 , the capsule filter of the present invention includes a soft shell 1, a filter element 2 is arranged inside the soft shell 1, and the soft shell 1 is detachably connected to the filter element 2, which is beneficial to the timely cleaning and replacement of the filter element 2 and improves the convenience of use.

[0034] Among them, please refer to the attached Figure 1-3 , in some shown specific embodiments, the soft shell 1 can be a circular tubular shell. At the same time, the cross-sectional diameter of the soft shell 1 can be 20 mm, so that the soft shell 1 can be placed in a liquid storage container 4 such as a mineral water bottle and can be easily taken out from the liquid storage container 4. The soft shell 1 is convenient to carry and has a flexible use scenario. It can be understood that this is not a specific limitation on the size of the soft shell 1, and those skilled in the relevant art can make replacements according to the actual application scenario. For example, in some other specific embodiments, the cross-sectional diameter of the soft shell 1 can be 30 mm, 45 mm, etc.

[0035] The soft shell 1 is preferably but not limited to a food-grade silica gel shell. The soft shell 1 includes a water inlet end 11 and a water outlet end 12. The water inlet end 11 and the water outlet end 12 are distributed along the axis direction of the soft shell 1. The soft shell 1 is provided with a water inlet hole 111 for liquid to flow into the soft shell 1 at the water inlet end 11, and a water outlet hole 121 for liquid to flow out of the soft shell 1 at the water outlet end 12. In some shown specific embodiments, the aperture of the water inlet hole 111 is larger than the aperture of the water outlet hole 121, which is beneficial to the liquid flowing into the soft shell 1 to fully filter and purify the liquid.

[0036] Please refer to the attached Figure 1 and Figure 4, on the inner wall of the soft shell 1, there are bone strips 13, and the bone strips 13 are specifically arc-shaped convex strips. The length direction of the bone strips 13 is parallel to the axis direction of the soft shell 1. Inside the soft shell 1, there is a filter element 2. The filter element 2 is preferably but not limited to a sintered coconut shell activated carbon water purification filter element 2. The sintered coconut shell activated carbon water purification filter element 2 can filter fine sediment, metals and other particulate matters in the liquid, as well as residual chlorine, while preserving minerals beneficial to the human body. The filter element 2 is inserted into the soft shell 1 from the water inlet hole 111. The filter element 2 is adapted to the inner wall of the soft shell 1 so that the outer wall of the bone position abuts against the outer wall of the filter element 2, and the bone position fastens the filter element 2. The filter element 2 is fixed in the soft shell 1. The inner wall of the soft shell 1 spaces the filter element 2 through the bone position, so that a gap is formed between the filter element 2 and the inner wall of the soft shell 1. When the liquid flows into the gap between the filter element 2 and the soft shell 1, it can increase the contact area between the liquid and the filter element 2 and increase the filtering time of the liquid, enabling the filter element 2 to fully play its filtering role.

[0037] At this time, please refer to the appendix Figure 1-3 , the aperture of the water inlet hole 111 is larger than the aperture of the water outlet hole 121, which is beneficial for the filter element 2 to be inserted into the soft shell 1 from the water inlet hole 111 and can reduce the possibility of the filter element 2 detaching from the inside of the soft shell 1 from the water inlet hole 111. The setting of the soft shell 1 facilitates the disassembly and assembly of the filter element 2. The filter element 2 is hermetically connected to the inner wall of the soft shell 1 at the water outlet end 12, so as to force the liquid to flow through the filter element 2 and then flow out from the water outlet hole 121, and the liquid is fully filtered.

[0038] The capsule filter can be used in the purification and filtration of tap water. The liquid flows into the soft shell 1 through the water inlet hole 111, passes through the filter element 2 and then flows out of the soft shell 1 through the water outlet hole 121. The filter element 2 filters and purifies the liquid. After the capsule filter is used for a period of time, the impurities filtered by the filter element 2 are likely to block the pores inside the filter element 2, affecting the filtering effect of the filter element 2. Pulling out the filter element 2 from the water inlet hole 111 of the soft shell 1 can clean or replace the filter element 2, which is convenient to operate and helps reduce the use cost. The disassembly and assembly of the filter element 2 are convenient. Compared with the traditional adsorption filter, there is no need for overall replacement, and the filter element 2 can be replaced frequently at high frequencies, fully ensuring the filtering and purification effect of the liquid.

[0039] Embodiment 2:

[0040] The difference between this embodiment and Embodiment 1 is that in this embodiment, further structural optimization is carried out on the soft shell 1 of the present utility model. Please refer to Figures 4 to 7 .

[0041] Please refer to Figures 4 to 6 , in this embodiment, there are several bone strips 13. Specifically, there can be four bone strips 13. The several bone strips 13 are arranged at intervals along the annular inner wall of the soft shell 1, which is beneficial to increasing the space between the filter element 2 and the inner wall of the soft shell 1, further increasing the contact area between the liquid and the filter element 2, so that the liquid can be fully filtered and purified.

[0042] In a preferred embodiment, the soft shell 1 is provided with a side hole 14 penetrating through the side wall of the water outlet end 12. The side hole 14 is specifically an oval hole. When the soft shell 1 is immersed in the liquid, the liquid can enter the soft shell 1 through the side hole 14. The setting of the side hole 14 is beneficial for the liquid to enter the soft shell 1 more smoothly and contact the filter element 2. At the same time, the side hole 14 provides an avoidance space for the installation process of the filter element 2, facilitating the quick insertion of the filter element 2 into the soft shell 1 and improving the convenience of disassembly and assembly. In some specific embodiments shown, a plurality of side holes 14 are provided, such as two. The plurality of side holes 14 are spaced apart on the side wall of the soft shell 1, which can increase the water inflow into the soft shell 1 and the filter element 2.

[0043] In a preferred embodiment, the soft shell 1 is provided with a water inlet notch 15 on the water inlet end 11. The water inlet notch 15 is located on one side of the water inlet hole 111 and communicates with the water inlet hole 111. The water inlet notch 15 extends to the side wall of the soft shell 1, and the liquid can enter the water inlet hole 111 along the water inlet notch 15. When the liquid is less, the setting of the water inlet notch 15 is beneficial for the remaining small amount of liquid in the container to enter the soft shell 1, and the filter element 2 fully filters the remaining liquid. At the same time, the setting of the water inlet notch 15 is beneficial for the disassembly and assembly of the filter element 2. In some specific embodiments shown, a plurality of water inlet notches 15 are provided, such as two. The plurality of water inlet notches 15 surround the outside of the water inlet hole 111 and are spaced apart.

[0044] In a preferred embodiment, a sealing ring 16 is provided on the inner wall of the water outlet end 12 of the soft shell 1. The soft shell 1 is hermetically connected to the filter element 2 at the sealing ring 16. Specifically, the sealing ring 16 can be integrally formed with the soft shell 1 to ensure the sealing between the soft shell 1 and the filter element 2. At this time, after the liquid enters the soft shell 1 through the water inlet hole 111, it needs to pass through the filter element 2 for filtration and then flow out through the water outlet hole 121. The sealing ring 16 restricts the flow path of the liquid to enable the liquid to be fully filtered and purified. Further, a plurality of sealing rings 16 can be provided. The plurality of sealing rings 16 are spaced apart along the axial direction of the soft shell 1 to increase the sealing between the soft shell 1 and the filter element 2. In some specific embodiments shown, the distance between the center of the sealing ring 16 and the center of the water outlet hole 121 is 10 - 30 mm. Specifically, the distance between the center of the sealing ring 16 and the center of the water outlet hole 121 can be 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, etc. When a plurality of sealing rings 16 are provided, the distance between the center of each sealing ring 16 and the center of the water outlet hole 121 is within 10 - 30 mm, which is beneficial for the liquid to fully contact the filter element 2 and enables the filter element 2 to play a role in filtration and purification.

[0045] In a preferred embodiment, an outlet pipe 17 is provided at the water outlet hole 121 of the soft shell 1. The outlet pipe 17 is communicated with the soft shell 1. The liquid filtered by the filter element 2 flows out through the outlet pipe 17. The outlet pipe 17 includes an outlet hole 121 channel and a communication channel. The liquid flowing out of the outlet pipe 17 flows through the communication channel and the outlet hole 121 channel in sequence, and finally flows out at the outlet hole 121 channel. The outlet pipe 17 is communicated with the soft shell 1 at the communication channel. Among them, the outlet hole 121 channel is a conical channel, and the aperture of the outlet hole 121 channel gradually increases from the end of the outlet pipe 17 close to the soft shell 1 to the end away from the soft shell 1, which is beneficial to externally connect a pipe for liquid circulation to the outlet pipe 17, so that the filtered liquid can flow out of the outlet pipe 17 smoothly.

[0046] Please refer to Figure 6 and Figure 7 , on the side of the filter element 2 close to the water outlet hole 121, an ultrafiltration membrane 3 is provided. The ultrafiltration membrane 3 is preferably but not limited to a PVC ultrafiltration membrane with a pore size of 0.01 μm. The ultrafiltration membrane 3 is specifically a circular membrane sheet adapted to the soft shell 1. The ultrafiltration membrane 3 can filter fine sediment, metal and other particulate matters in the liquid, as well as bacteria, viruses, algae and tiny aquatic organisms in the liquid, so as to ensure the filtration effect of the capsule filter.

In some specific embodiments shown, the liquid storage container 4 can be a water bucket, and tap water is stored in the water bucket. When the capsule filter is sunk to the bottom in the water bucket and the water pump pumps water, the tap water enters the soft shell 1 through the water inlet hole 111 and the side hole 14, and is filtered and purified by the filter element 2. The filtered tap water is pumped out through the outlet pipe 17 and the connecting pipe 41 in sequence.

[0050] In a preferred embodiment, the water supply device further includes a middle water tank, which is arranged on one side of the water pump so that the filtered tap water can flow into the middle water tank. A heating component is arranged in the middle water tank. Specifically, the heating component can be an electric heating tube.
