Description

Technical Field

[0001] This invention relates to the technical field of filters, particularly to the water supply structure of outdoor filters and such filters.

Background Art

[0002] With the popularization of activities such as outdoor sports, hiking, and wilderness exploration, and the increasing importance of emergency countermeasures for disaster response, people's demand for the safety of outdoor water drinking is growing. Outdoor water sources such as river water, lake water, and streams generally contain large particle impurities such as soil and rust, bacteria, viruses, and the cysts of protozoa such as Giardia lamblia, Cryptosporidium, and heavy metals of chemical pollutants. Although the conventional boiling method is effective, it takes time and consumes energy, and cannot remove particles and heavy metals of chemical pollutants. Therefore, outdoor filters have become an important equipment for solving the problem of outdoor water drinking.

[0003] Moreover, the filter includes a cup body, and a filtration assembly and a water supply assembly are installed in the cup body. After the external water source enters the cup body, it is filtered by the filtration assembly and then flows out through the water supply assembly, and the water supply assembly includes a faucet. However, all the faucets in the prior art are fixedly installed on the cup body. Therefore, when actually used, in order to facilitate portability or other transportation requirements, the water supply pipe is generally short, so that water can only be supplied by externally attaching a hose, that is, direct water supply is not possible. Also, after use, there may be residual water in the water supply pipe, so the residual water is likely to flow into the filter. Therefore, there are design drawbacks from the perspectives of the convenience of use, the cleanliness of the filter body, and even the protection of electrical equipment.

Modes for Carrying Out the Invention

[0022] The following will further describe in more detail the specific embodiments of the present invention with reference to the drawings.

[0023] As shown in Figures 1 to 7 and Figure 12, the filter water supply structure includes a filter body and a water tap 18 installed on the filter body, the water tap 18 is used to form a through water channel with a built-in filter element assembly 2 installed inside the filter body, a pivot shaft 20 is installed on the water tap 18 and the water tap 18 is rotatable relative to the filter body via the pivot shaft 20, and a water supply pipe 19 is installed on one side of the water tap 18.

[0024] Therefore, during actual use, the water tap 18 is in at least two states: in the first state, the water supply end of the water supply pipe 19 of the water tap 18 is located within the outer wall of the filter body, and in the second state, the water tap 18 rotates until the water supply end of the water supply pipe 19 extends beyond the outer wall of the filter body.

[0025] Therefore, by installing the water tap 18 so as to be rotatable, the water tap 18 can rotate until the water supply end of the water supply pipe 19 exceeds the outer wall of the filter body, and thus water can be supplied directly after rotation, and if there is residual water in the water supply pipe, it will not flow into the filter, and the tap can return after cleaning the residual water. Naturally, in addition to direct water supply, a hose can be attached externally or an extension nozzle can be detachably connected after rotation.

[0026] Furthermore, the rotation angle of the water tap 18 is 0 to 360°, with the water supply end of the water supply pipe 19 pointing toward the center line being 0°, and the rotatable angle of the water tap being 360°.

[0027] Preferably, the rotation angle of the water tap 18 is within the range of 0 to 180°, and the rotation of the water tap 18 is restricted so as not to exceed 180°. Furthermore, in order to ensure that the water tap 18 holds its stop when it is opened to its maximum angle for water supply, a stopping force is applied in the clockwise direction of rotation to prevent the water tap 18 from rotating. In addition, a stopper holding structure is installed at both the 0° position and the 180° position of the water tap 18, and this stopper holding structure may be a stopper or an elastic stopper.

[0028] In a preferred embodiment, the water tap 18 is installed eccentrically with respect to the filter body, and in the first state, the water supply end of the water supply pipe 19 of the water tap 18 is close to the centerline of the filter body, and in the second state, the water tap 18 rotates to a centerline away from the filter body where the water supply end of the water supply pipe 19 is.

[0029] Therefore, in actual use, due to the eccentric installation of the water tap 18, the water tap 18 can be more easily housed inside the cup cover 1, and the range of length settings for the water tap 18 may be larger.

[0030] As shown in Figures 3 to 5 and Figure 12, the related structure of the water tap 18 further includes a water channel conversion member 21 installed inside the filter body, and the water tap 18 is rotatably installed on the water channel conversion member 21. The water channel conversion member 21 is used to communicate with the built-in filter element assembly 2 and the water tap 18, respectively. The water tap 18 also includes a water supply member 14, and a water supply pipe 19 is installed on one side of the water supply member 14. The pivot shaft 20 is installed at the bottom of the water supply member 14, and the water channel conversion member 21 has a second passage that allows the pivot shaft 20 to be placed and rotated in accordance with the pivot shaft 20.

[0031] In a specific embodiment of a preferred mounting structure between the water tap 18 and the water channel conversion member 21, the water tap 18 further includes a retaining plate 15 and a knob 16, and the retaining plate 15 is attached to the water channel conversion member 21 by pressing the water supply member 14 and the knob 16 together, forming a mounting groove between the knob 16 and the water channel conversion member 21. Here, the pressing is performed using high temperature and high pressure conditions, causing the materials to undergo physicochemical changes during thermocompression, ultimately forming a firmly bonded overall structure, and thus enabling connection between the water supply member 14 and the knob 16 via the retaining plate 15.

[0032] Furthermore, the filter body includes an upper cover 35, and an opening is provided in the upper cover 35 to expose the water channel conversion member 21. The upper cover 35 has a convex ring installed on the outside of the opening, and the convex ring is located within the mounting groove.

[0033] As shown in Figures 1 to 7 and Figure 12, the filter's water channel structure includes a built-in filter element assembly 2, a UV sterilization assembly 37, and a water tap 18. A water channel is provided between the water tap 18 and the built-in filter element assembly 2, with some or all segments of this water channel being configured as sterilization passages. These sterilization segments are exposed to the light irradiation range of the UV sterilization assembly 37, which is used to sterilize the water passing through these passages.

[0034] Therefore, in actual use, by installing the UV sterilization assembly 37 between the filter element assembly 2 containing the UV sterilization assembly and the faucet 18, that is, because the UV sterilization assembly sterilizes the water that is about to flow out, it is possible to ensure that the water that flows out or the water that is about to be drunk or used is sterilized and clean, and sterilizing filtered water has a higher sterilization effect than sterilizing unfiltered water. In addition, since the UV sterilization assembly 37 is used to sterilize the water that passes through the sterilization passage, it sterilizes the flowing water and does not require a separate individual sterilization system, which contributes to reducing the overall volume of the filter, making it easy to carry.

[0035] Furthermore, the UV sterilization assembly 37 includes a water pipe, which is a sterilization passage and a segment of a connecting waterway, and the UV sterilization assembly 37 further includes a UV bulb installed outside and / or inside the sterilization passage, and when the UV bulb is located outside the sterilization passage, the sterilization passage is transparent and can allow light rays to pass through.

[0036] As shown in Figures 2 to 7 and Figure 12, the connecting waterway includes a waterway conversion member 21, which communicates with the built-in filter element assembly 2 and the water tap 18, respectively. A first passage is installed in the waterway conversion member 21, and the end of the sterilization passage communicates with the first passage.

[0037] In a preferred embodiment, the water channel conversion member 21 includes an intake chamber 45 and a supply chamber 44 distributed in the axial direction, and the intake chamber 45 and the supply chamber 44 are separated by a partition plate, with a first passage provided in the side walls of both the intake chamber 45 and the supply chamber 44.

[0038] Therefore, when installed, the top of the built-in filter element assembly 2 is connected to the water intake chamber 45 at the bottom of the water channel conversion member 21, and the water tap 18 is connected to the water supply chamber 44 at the top of the water channel conversion member 21, and the UV sterilization assembly 37 is installed laterally to the water channel conversion member 21. Also, since it is installed laterally, that is, the sterilization passage is also located laterally, the sterilization passage may also be called a lateral passage.

[0039] Next, the built-in filter element assembly 2, the water channel conversion member 21, and the water tap 18 are connected to form an integrated filter cylinder assembly. Thus, the filter cylinder assembly can be made into a single independent component, and is therefore detachable from the filter body.

[0040] Specifically, the filter body includes an upper cover 35, and a filter element sleeve extending downward is connected to the upper cover 35. The filter cylinder assembly and the filter element sleeve are detachably connected, and an opening is provided in the upper cover 35 to expose the water tap 18.

[0041] Therefore, during actual use, it is detachably connected to facilitate replacement and maintenance.

[0042] Furthermore, a water supply passage and a water intake passage are installed circumferentially on the upper part of the filter element sleeve, and both ends of the sterilization passage communicate with the water supply passage and the water intake passage, respectively. In addition, two first passages communicating with the UV sterilization assembly 37 are installed in the water channel conversion member 21, one of which is located on the side wall of the water intake chamber 45 and is used to communicate with the water supply passage, and the other first passage is located on the side wall of the water supply chamber 44 and is used to communicate with the water intake passage. A seal ring 17 is installed between the water intake passage and the water supply passage to separate them, thereby achieving a seal and ensuring that there is no interference between the water intake passage and the water supply passage.

[0043] Furthermore, the UV sterilization assembly 37 is installed laterally to the water channel conversion member 21 and also laterally to the filter element sleeve. The filter element sleeve and the water channel conversion member 21 are fitted together, thereby ensuring sterilization and facilitating cleaning and replacement without hindering the attachment and detachment of the filter cylinder assembly.

[0044] In a preferred embodiment, the mounting structure for the UV sterilization assembly 37 is such that a first mounting seat extends laterally from the filter element sleeve, and the UV sterilization assembly 37 is mounted to the first mounting seat.

[0045] As shown in Figures 1 to 12, the detachable filter cylinder assembly includes a built-in filter element assembly 2, which includes a filter element housing 26 and at least one type of filter element material, the filter element housing 26 is provided with a first inlet, the filter element housing 26 includes a filter element upper cover 23, the filter element upper cover 23 is provided with a first outlet, and the filter element upper cover 23 is provided with a first connection part for detachably connecting to a conversion member.

[0046] Therefore, during actual use, the conversion member is installed inside the filter body and connected to the built-in filter element assembly 2, and the conversion member and the built-in filter element assembly 2 are detachably connected. Specifically, the conversion member and the filter element upper cover 23 are detachably connected, so the built-in filter element assembly 2 is detachable from the filter body and is also easy to replace and clean.

[0047] Here, the conversion member is diverse and may be a backwash fitting 50 or a water channel conversion member 21, and since it is detachable from the built-in filter element assembly 2, different conversion members can be exchanged. In the case of the backwash fitting 50, that is, the conversion member includes the backwash fitting 50, and the backwash fitting 50 includes a connecting head, the connecting head includes a second inlet and a second outlet distributed in the axial direction, and the connecting head has a second connecting part that is detachably connected to the first connecting part at the end where the second outlet is installed, and the second outlet communicates with the first outlet.

[0048] Therefore, during actual use, the installation of the backwash fitting 50 allows for backwashing of the built-in filter element assembly 2, thereby eliminating the need for multiple replacements and protection of the filter element material. This is because, with prolonged use, the inside of the built-in filter element assembly 2 becomes dirty, requiring replacement of the built-in filter element assembly 2, which increases the cost of use and creates an undesirable experience. Alternatively, one might employ manual cleaning instead of replacement, which involves disassembling the built-in filter element assembly 2 and individually cleaning the filter element material. However, some filter element materials are inherently brittle, and individual manual cleaning can damage them, thereby affecting the filtration effect. Furthermore, disassembly and reassembly are not particularly convenient. For this reason, the backwash fitting 50 can avoid the above problems.

[0049] Furthermore, the connecting head has a capsule bag 51 with a third inlet at the end where the second water inlet is installed, and the capsule bag 51 is made of an elastic material, and the capsule bag 51 forms a storage chamber, or the capsule bag 51 and the inner wall of the connecting head form a storage chamber, and the storage chamber forms a third outlet that penetrates the second water inlet, and the third outlet communicates with the second inlet.

[0050] Therefore, during actual use, water is placed in the containment chamber, and the water from the containment chamber is allowed to enter the connecting head through the third outlet and then into the built-in filter element assembly 2 for backwashing. Moreover, because the third outlet of the capsule bag 51 is made of an elastic material, when the third outlet is brought into contact with another suitable container or jug ​​for washing, it forms a relative seal structure, thereby preventing water leakage and enabling pressurized washing.

[0051] As shown in Figures 9 to 11, the structure of the connecting head is such that it includes a radially expanding segment and a radially contracting segment, with a second inlet installed in the radially expanding segment and a second outlet installed in the radially contracting segment.

[0052] Furthermore, the structure for detachable connection is such that the first connection part is a radially extending pin column and the second connection part is an L-shaped notch that fits with the first connection part, or the first connection part is an L-shaped notch and the second connection part is a radially extending pin column that fits with the first connection part.

[0053] Therefore, in actual use, the L-shaped notch and pin post fit together to achieve a detachable connection.

[0054] As shown in Figures 1 to 7 and Figure 12, when the conversion member is a waterway conversion member 21, that is, the conversion member includes a waterway conversion member 21, and the waterway conversion member 21 is provided with a third connection part at its lower end that is detachably connected to a first connection part.

[0055] Furthermore, the structure for detachable connection is such that the first connection part is a radially extending pin column and the third connection part is an L-shaped notch that fits with the first connection part, or the first connection part is an L-shaped notch and the third connection part is a radially extending pin column that fits with the first connection part.

[0056] Therefore, in actual use, the L-shaped notch and pin post fit together to achieve a detachable connection.

[0057] As shown in Figures 1 to 8 and Figure 12, the structure of the filter body includes a filter body, which includes a cup body 4, and a mounting chamber is formed surrounding the inner wall of the cup body 4. An upper cover 35 is installed above the mounting chamber, and a filter element sleeve extending downward is connected to the upper cover 35. The filter element sleeve divides the mounting chamber into a left chamber and a right chamber, and a filter element assembly 2 built into the filter element sleeve is detachably connected to it. An electrical control assembly 5 is installed in the left chamber in the direction laterally from the filter element sleeve.

[0058] Therefore, in actual use, the installation of the filter element sleeve divides the mounting chamber into a left chamber and a right chamber, and the built-in filter element assembly 2 is placed inside the filter element sleeve, while the electrical control assembly 5 is mounted outside the filter element sleeve, thus separating the waterway and the circuit, and thus reducing the influence of the electrical equipment components inside the waterway. Moreover, by adopting a left-right layout, the height can be reduced, and it is also easier to carry and use. Furthermore, the filter element assembly 2 built inside the filter element sleeve is detachably connected, thereby allowing the built-in filter element assembly 2 to be centrally integrated inside the filter element sleeve, and facilitating the attachment, detachment, and replacement of subsequent built-in filter element assemblies 2.

[0059] Furthermore, the left chamber has a UV sterilization assembly 37 installed laterally to the filter element sleeve, and the UV sterilization assembly 37 is installed at the upper end of the electrical control assembly 5. The filter element sleeve includes an upper filter element sleeve 36 and a lower filter element sleeve 38, and a water supply passage and a water intake passage are installed circumferentially in the upper filter element sleeve 36, with a lateral passage between the water supply passage and the water intake passage, and the UV sterilization assembly 37 is used to sterilize the water passing through the lateral passage.

[0060] Next, a water channel conversion member 21 is connected to the water inlet of the built-in filter element assembly 2. The water channel conversion member 21 includes an intake chamber 45 and a supply chamber 44 distributed in the axial direction. The water channel conversion member 21 is provided with two first passages that communicate with the UV sterilization assembly 37. One of these first passages is located on the side wall of the intake chamber 45 and is used to communicate with the supply passage, and the other first passage is located on the side wall of the supply chamber 44 and is used to communicate with the intake passage. A seal ring 17 is installed between the intake passage and the supply passage to separate them.

[0061] As shown in Figures 1 to 12, the specific structure of the filter, as described above, includes a cup cover 1 and a filter body, with a water tap 18 installed on the filter body, and the filter body includes an upper cover assembly 3, a cup body 4 and a base 6, with a filter element assembly 2, a UV sterilization assembly 37, a water channel conversion member 21 and an electrical control assembly 5 built into the cup body 4, a water intake port installed on the base 6, a water intake silicone rubber stopper 7 attached to the water intake port, and preferably a silicone rubber pad 8 installed on the bottom surface of the base.

[0062] Here, the water intake silicone rubber stopper 7 serves a dustproof and waterproof function, opens when in use, and the silicone rubber pad 8 is located at the bottom of the entire machine, thereby increasing the frictional force.

[0063] The structure of the water tap 18 includes a water supply member 14, a water supply pipe 19 is installed on one side of the water supply member 14, a pivot shaft 20 is installed at the bottom of the water supply member 14, and the bottom of the water supply member 14 is connected to a knob 16 via a retaining plate 15. Both the pivot shaft 20 and the knob 16 have protrusions corresponding to the retaining plate 15, and the bottom of the retaining plate 15 abuts against the protrusions.

[0064] The structure of the water channel conversion member 21 includes an intake chamber 4 5 and a supply chamber 4 4 distributed in the axial direction, and the intake chamber 4 5 and the supply chamber 4 4 are separated by a partition plate, with a first passage installed in the side walls of both the intake chamber 4 5 and the supply chamber 4 4.

[0065] The structure of the built-in filter element assembly 2 includes a filter element housing 26 and at least one type of filter element material, wherein the filter element material includes one or more types from a carbon-containing origami filter element 28, an ultrafiltration membrane 25, and a carbon rod 22. If there are three types, they are, from bottom to top, the carbon-containing origami filter element 28, the ultrafiltration membrane 25, and the carbon rod 22, i.e., triple filtration.

[0066] Here, the ultrafiltration membrane 25 is 0.01 μm thick, and the carbon-containing origami filter element 28 and the ultrafiltration membrane 25 filter out most fine particles and heavy metals, while the carbon rod 22 improves texture. Therefore, assuming a small volume and weight are guaranteed, multi-layer filtration can achieve highly efficient purification of various complex outdoor water sources, and the UV sterilization assembly 37 ensures that clean pre-treated water is introduced, guaranteeing a stable sterilization rate.

[0067] Furthermore, the filter element housing 26 includes a connecting sleeve 27 and a filter element upper cover 23 that covers the upper part of the connecting sleeve 27, and a filter element downer cover 26 is connected to the lower end of the first cylindrical body, a first inlet is provided in the filter element downer cover 26 and a first outlet is provided in the filter element upper cover 23.

[0068] The water tap 18, the water channel conversion member 21, and the built-in filter element assembly 2 can together constitute a filter cylinder assembly that is detachable from the filter body.

[0069] The structure between the faucet 18 and the water channel conversion member 21 is such that, firstly, the water channel conversion member 21 has a second passage provided to allow the pivot shaft 20 to be placed and rotated in accordance with the pivot shaft 20, and the water supply member 14 communicates with the water supply chamber 4, and a mounting groove is formed between the knob 16 and the water channel conversion member 21 for placing the convex ring of the upper cover 35.

[0070] The connection structure between the built-in filter element assembly 2 and other components is such that the built-in filter element assembly 2 communicates with the water intake chamber 4 5, that is, the first outlet communicates with the water intake chamber 4 5 of the water channel conversion member 21, and the first inlet communicates with the water intake pipe 39 of the upper cover assembly 3. Furthermore, the filter element downer cover 26 and the water channel conversion member 21 are detachably connected, using an L-shaped notch and a pin column.

[0071] The structure of the upper cover assembly 3 includes an upper cover 35, to which a filter element sleeve extending downward is connected to the bottom of the upper cover 35, and a convex ring is installed on the top of the upper cover 35 so as to fit the knob 16 and the water channel conversion member 21, and a built-in filter element assembly 2 that is detachable from the filter element sleeve is built-in, and the filter element sleeve includes an upper filter element sleeve 36 and a lower filter element sleeve 38, and a water intake pipe 39 is installed at the bottom of the lower filter element sleeve 38.

[0072] Furthermore, a water supply passage and a water intake passage are installed in the first passage corresponding to the water channel conversion member 21 of the upper sleeve 36 of the filter element, and the water supply passage and the water intake passage are connected to the UV sterilization assembly 37.

[0073] The structure of the UV sterilization assembly 37 includes a water tube, and a UV bulb is installed on the outside and / or inside of the water tube. When the UV bulb is located outside the sterilization passage, the sterilization passage is transparent and allows light rays to pass through.

[0074] Furthermore, the UV sterilization assembly 37 is located on one side of the water channel conversion member 21 and communicates with the first passage, and both ends of the water pipe communicate with the water intake chamber 4 5 and the water supply chamber 4 4, respectively.

[0075] Preferably, the mounting structure for the UV sterilization assembly 37 is such that the UV sterilization assembly 37 is located on one side of the filter element sleeve, and both ends of the water pipe are in communication with the water supply passage and water intake passage of the filter element sleeve, respectively, and a first mounting seat extends laterally from the filter element sleeve, and the UV sterilization assembly 37 is attached to the first mounting seat.

[0076] The structure of the electrical control assembly 5 includes a main control board 30, a battery 32, and a water pump 33, and the main control board 30 is electrically connected to the battery 32 and the water pump 33, respectively, and the water pump 33 is connected to a built-in filter element assembly 2 and used to extract water from an external water source.

[0077] Furthermore, the electrical control assembly 5 further includes an upper bracket 31 and a lower bracket 34 connected to each other, with a main control board 30 installed on the upper bracket 31, a water pump 33 installed between the upper bracket 31 and the lower bracket 34, and several batteries 32 arranged around the outside of the water pump 33.

[0078] Furthermore, the cup body 4 is equipped with a key and a Type-C port, and the main control board 30 is electrically connected to the key and the Type-C port, respectively. Pressing the key activates the water pump 33 and charges the battery 32 via Type-C.

[0079] Therefore, the completed operating principle is as follows: First, the user presses a key, thereby activating the water pump 33. Subsequently, after the water pump 33 has activated, an external water source is extracted and transported to the intake pipe 39 of the lower sleeve 38 of the filter element. At this time, the water enters the filter element sleeve via the intake pipe 39 of the lower sleeve 38 of the filter element, and then enters the built-in filter element assembly 2 from the bottom of the built-in filter element assembly 2. The water that enters the built-in filter element assembly 2 then undergoes triple filtration in order through the carbon-containing origami filter element 28, the ultrafiltration membrane 25, and the carbon rod 22. The filtered water then enters the intake chamber 45. Subsequently, the water in the intake chamber 45 flows to the UV sterilization assembly 37 and enters the water pipe of the UV sterilization assembly 37 for sterilization. The sterilized water then flows to the water channel conversion member 21 and enters the water supply chamber 44, and subsequently flows to the water supply pipe 19 of the faucet for water supply.

[0080] Furthermore, many components that pass through the entire water flow process are each fitted with a seal ring 17 at their connection points, thereby forming a single, complete, and sealed waterway.

[0081] Next, the complete structure of this invention enables multi-layer filtration and employs UV sterilization to ensure water cleanliness. Furthermore, UV sterilization sterilizes the flowing water, and the components inside the cup body 1 are arranged on the left and right sides to separate the water channel and circuit. This rational layout reduces the overall volume, ensuring the portability and safety of the product.

[0082] Furthermore, the rotating structure of the water tap 18 allows for direct water supply by rotating the tap 18 before each use, preventing residual water from dripping onto the filter body. In addition, the conversion member and the built-in filter element assembly are detachable, and the conversion member is installed inside the filter body, so the built-in filter element assembly 2 is detachable from the filter body, making it easier to replace and clean. If the conversion member is a backwash fitting 50, backwashing can be achieved, thereby eliminating the need for multiple replacements and protection of the filter element material.

[0083] The above explains the basic principles, main features, and advantages of the present invention. Furthermore, since the present invention is not limited to the above embodiments, the present invention has various further variations and improvements, provided that they do not depart from the principles and scope of the present invention, and all of these variations and improvements are included within the scope of the present invention for which protection is claimed.
