Description

Technical Field

[0001] This utility model belongs to the field of drinking water equipment, specifically relating to a water purifier. Background Technology

[0002] Water purifiers, as devices that purify water, can bring it up to safe and healthy drinking standards. As people increasingly value the health of their drinking water, water purifiers are gradually becoming indispensable daily necessities.

[0003] Water purifiers typically have a flip-up filter holder and filter cartridges inserted into it. Water flows through the filter holder and into the filter cartridges for filtration. However, current flip-up filter holders lack a positioning structure, resulting in the filter holder being unable to stay in a suspended position. When users need to replace the filter cartridges, they must first use one hand to flip the filter holder to a certain angle and hold it to keep it in a suspended position, and then use the other hand to align and replace the filter cartridge. This two-handed operation is very inconvenient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a water purifier that solves the problem that the filter cartridge holder cannot stay in the suspended position for filter cartridge replacement.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: A water purifier includes a mounting bracket with a receiving cavity and a rotating shaft hole, a filter element seat with a rotating part, and a filter element with its end inserted into the filter element seat. The filter element seat is rotatably connected to the mounting bracket through the rotating part passing through the rotating shaft hole. The filter element and the filter element seat rotate together to switch between a working position located in the receiving cavity and a suspended position extending out of the receiving cavity. The filter element seat is provided with a stop member, and the mounting bracket is provided with a positioning member. When the filter element seat rotates to the suspended position, the stop member cooperates with the positioning member to keep the filter element seat in the suspended position. This technical solution has the following technical effects:

[0006] This invention rotatably connects the rotating part to the mounting bracket, allowing the filter element holder to flip between a working position within the receiving cavity and a suspended position extending out of the receiving cavity. When the user needs to replace the filter element, simply flip the filter element holder and filter element to the suspended position, remove the old filter element, insert the new filter element into the filter element holder, and then flip the filter element holder and filter element back to the working position to complete the filter element replacement. Because the filter element holder and mounting bracket are respectively equipped with a stop and a positioning component, when the filter element and filter element holder are in the suspended position, the stop and positioning components can cooperate to prevent the filter element and filter element holder from rotating back to the working position under their own weight, ensuring that the filter element and filter element holder are always stably in the suspended position. When replacing the filter element, the user does not need to hold the filter element holder to keep it in the suspended position by hand, making the filter element replacement operation more convenient. After the filter element is installed, the user can apply external force to the filter element to disengage the stop and positioning components from the cooperating state, and then rotate the filter element and filter element holder back to the working position. The operation is simple and improves the user experience.

[0007] In the aforementioned water purifier, the stop component is a stop groove located on the outer wall of the rotating part. The positioning component includes a positioning seat, a positioning spring, and a positioning ball. The positioning seat has a positioning groove with its opening facing the rotating shaft hole. The positioning spring is located in the positioning groove. By pushing the positioning ball into the stop groove, the filter cartridge holder is stopped in the suspended position. When the filter cartridge holder rotates to the suspended position, the stop groove rotates with the rotating part until it aligns with the positioning ball. At this time, the positioning ball is engaged in the stop groove, with part of the positioning ball located in the stop groove and part in the positioning groove, preventing the rotating part from continuing to rotate and keeping the filter cartridge holder in the suspended position. The structure is simple and the limiting is stable, facilitating the user's filter cartridge replacement operation. At the same time, the clicking sound of the positioning ball engaging the stop groove also indicates to the user that the filter cartridge has rotated to the suspended position, resulting in a better user experience.

[0008] In the aforementioned water purifier, the inner wall of the stop groove is an arc surface, and the maximum depth of the stop groove is less than the radius of the positioning ball. This ensures that the positioning ball extends into the stop groove to less than half its own height. When the user needs to rotate the filter element and filter element holder from the suspended position back to the working position, simply pressing the filter element will cause the positioning ball to disengage from the stop groove under the push of the arc surface, making the operation more convenient and effortless for the user.

[0009] In the aforementioned water purifier, a limiting groove is also provided on the rotating part. When the filter cartridge holder flips to the working position, the positioning spring pushes the positioning ball into the limiting groove, thus keeping the filter cartridge holder in the working position. The limiting groove not only limits the movement of the filter cartridge and filter cartridge holder, but also provides a clicking sound to the user when the positioning ball is engaged in the limiting groove, indicating that the filter cartridge has rotated to the working position, resulting in a better user experience.

[0010] In the aforementioned water purifier, the mounting bracket has a mounting hole that extends radially along the shaft hole and communicates with it. The positioning seat passes through the mounting hole and is detachably connected to the mounting bracket. This detachable connection structure allows the positioning component to be removed from the mounting bracket and replaced individually if it is damaged, reducing maintenance and replacement costs.

[0011] In the aforementioned water purifier, the positioning seat and the mounting bracket are integrated into one structure, and the opening of the positioning groove is located on the inner wall of the rotating shaft hole. Integrating the positioning seat and the mounting bracket into one structure reduces assembly steps.

[0012] In the aforementioned water purifier, the stop component is a stop rib located on the rotating part, and the positioning component is a positioning rib located on the inner wall of the rotating shaft hole. When the filter element flips from the working position to the suspended position, the stop rib passes over the positioning rib and abuts against it, thus preventing the filter element seat from freely rotating back to the working position. This simple structure effectively limits the movement of the filter element, improving the user experience while reducing production costs.

[0013] In the aforementioned water purifier, a limiting rib is also provided on the inner wall of the rotating shaft hole. When the filter element is flipped from the suspended position to the working position, the stopping rib abuts against the limiting rib to prevent the filter element seat from continuing to rotate. During the process of the user flipping the filter element from the suspended position to the working position, the stopping rib passes over the positioning rib and rotates with the rotating part until the stopping rib abuts against the limiting rib. The limiting rib can prevent the filter element seat and filter element from continuing to rotate by abutting against the stopping rib, so that the filter element stays in the working position and reminds the user that the filter element has been installed in place, improving the user experience.

[0014] In the aforementioned water purifier, the mounting bracket includes a filter element support with a receiving cavity and a filter element seat support detachably connected to the top of the filter element support. A pivot hole is located on the filter element seat support. Because the filter element seat support, which has a pivot hole and is easily damaged, is detachably connected to the filter element support, when the filter element seat support becomes damaged due to excessive wear, it can be removed and replaced separately without replacing the entire mounting bracket, thus reducing maintenance costs.

[0015] In the aforementioned water purifier, two filter cartridge holders are provided. Each filter cartridge holder includes a base and inlet and outlet pipes located on both sides of the base. Rotating parts are located on the inlet and outlet pipes, respectively, and pass through the pivot holes of the two filter cartridge holders, allowing the filter cartridge holder to be rotatably connected to the mounting brackets. By providing two filter cartridge holders, the force on the filter cartridge holder during rotation is more even, preventing damage caused by excessive force on one side. Furthermore, by placing the two rotating parts on the inlet and outlet pipes respectively, the strength of the rotating parts is enhanced while reducing the space occupied by the rotating parts, thus reducing the overall volume of the filter cartridge holder.

[0016] The features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0036] The present invention discloses a water purifier, comprising a mounting bracket having a receiving cavity and a rotating shaft hole, a filter element seat having a rotating part, and a filter element having its end inserted into the filter element seat. The filter element seat is rotatably connected to the mounting bracket through the rotating part passing through the rotating shaft hole. The filter element and the filter element seat rotate together to switch between a working position located in the receiving cavity and a suspended position extending out of the receiving cavity. The filter element seat is provided with a stop member, and the mounting bracket is provided with a positioning member. When the filter element seat rotates to the suspended position, the stop member cooperates with the positioning member to keep the filter element seat in the suspended position. This invention rotatably connects the rotating part to the mounting bracket, allowing the filter element holder to flip between a working position within the receiving cavity and a suspended position extending out of the receiving cavity. When the user needs to replace the filter element, simply flip the filter element holder and filter element to the suspended position, remove the old filter element, insert the new filter element into the filter element holder, and then flip the filter element holder and filter element back to the working position to complete the filter element replacement. Because the filter element holder and mounting bracket are respectively equipped with a stop and a positioning component, when the filter element and filter element holder are in the suspended position, the stop and positioning components can cooperate to prevent the filter element and filter element holder from rotating back to the working position under their own weight, ensuring that the filter element and filter element holder are always stably in the suspended position. When replacing the filter element, the user does not need to hold the filter element holder to keep it in the suspended position by hand, making the filter element replacement operation more convenient. After the filter element is installed, the user can apply external force to the filter element to disengage the stop and positioning components from the cooperating state, and then rotate the filter element and filter element holder back to the working position. The operation is simple and improves the user experience.

[0042] Example 1:

[0043] A type of water purifier, such as Figures 1 to 9As shown, the system includes a mounting bracket 100, a filter element holder 300, and a filter element 400. The mounting bracket 100 has a receiving cavity 111 and a rotating shaft hole 121. The filter element holder 300 has a rotating part 340, which passes through the rotating shaft hole 121 and is rotatably connected to it, allowing the filter element holder 300 to be rotatably connected to the mounting bracket 100. The end of the filter element 400 is inserted into the filter element holder 300 and can rotate with the filter element holder 300. The filter element 400 and the filter element holder 300 have a working position and a suspended position. The filter element 400 and the filter element holder 300 rotate together to switch between the working position and the suspended position. The filter element holder 300 has a stop member 350, and the mounting bracket 100 has a positioning member 200. When the water purifier is working, such as... Figure 5 As shown, the filter element 400 and filter element holder 300 are in the working position, at which time the filter element 400 and filter element holder 300 are located in the receiving cavity 111, and water can be filtered; when the user needs to replace the filter element 400 of the water purifier, the filter element 400 and filter element holder 300 can be flipped to the suspended position, as shown. Figure 3 As shown, at this time, the filter element 400 and the filter element seat 300 extend obliquely out of the receiving cavity 111. The stop member 350, by cooperating with the positioning member 200, prevents the filter element seat 300 and the filter element 400 from freely rotating back to the working position, so that the filter element seat 300 stays in the suspended position, so that the user can replace the filter element 400 on the filter element seat 300. When the filter element 400 is installed, the user can apply external force to the filter element 400 to disengage the stop member 350 from the positioning member 200 from the cooperating state, so that the filter element 400 and the filter element seat 300 can be rotated back to the working position.

[0044] This invention rotatably connects the rotating part 340 to the mounting bracket 100, allowing the filter element holder 300 to flip between a working position within the receiving cavity 111 and a suspended position extending out of the receiving cavity 111. When the user needs to replace the filter element 400, simply flip the filter element holder 300 and the filter element 400 to the suspended position, remove the old filter element 400, insert the new filter element 400 into the filter element holder 300, and then flip the filter element holder 300 and the filter element 400 back to the working position to complete the replacement of the filter element 400. Because the filter element holder 300 and the mounting bracket 100 are respectively provided with a stop member 350 and a positioning member 200, the filter element 400 and the filter element 400 can be rotated between the working position and the suspended position. When the filter element 300 is in the suspended position, the stop 350 and the positioning element 200 can cooperate to prevent the filter element 400 and the filter element seat 300 from rotating back to the working position under their own weight, ensuring that the filter element 400 and the filter element seat 300 are always stably in the suspended position. When replacing the filter element 400, the user does not need to hold the filter element seat 300 in the suspended position by hand, making the filter element replacement operation more convenient. After the filter element 400 is installed, the user can apply external force to the filter element 400 to disengage the stop 350 and the positioning element 200 from the cooperating state, and then rotate the filter element 400 and the filter element seat 300 back to the working position. The operation is simple and improves the user experience.

[0045] like Figure 8 As shown, in this embodiment, the stop member 350 has a stop groove 351, which is provided on the outer wall of the rotating part 340 (i.e., the outer wall of the rotating part 340 facing the inner wall of the shaft hole 121), as shown. Figure 9As shown, the positioning component 200 includes a positioning seat 210, a positioning spring 220, and a positioning ball 230. The positioning seat 210 is fixed on the mounting bracket 100. The positioning seat 210 has a positioning groove 211, the opening of which faces the shaft hole 121. The positioning spring 220 is located inside the positioning groove 211. One end of the positioning spring 220 abuts against the inner wall of the positioning groove 211, and the other end abuts against the positioning ball 230, pushing the positioning ball 230 outward from the positioning groove 211 so that the positioning ball 230 abuts against the outer wall of the rotating part 340. When the filter element... When the filter element holder 300 rotates to the hovering position, the stop groove 351 rotates with the rotating part 340 until it aligns with the positioning ball 230. At this time, the positioning ball 230 is engaged in the stop groove 351, with part of the positioning ball 230 located in the stop groove 351 and part in the positioning groove 211, to prevent the rotating part 340 from continuing to rotate, so that the filter element holder 300 stays in the hovering position. The structure is simple and the limit is stable, which makes it easier for users to replace the filter element 400. At the same time, the clicking sound of the positioning ball 230 engaging the stop groove 351 can also indicate to the user that the filter element 400 has been rotated to the hovering position, resulting in a better user experience. Preferably, the stop groove 351 extends along the axial direction of the rotating part 340, and its inner wall is an arc surface. The maximum depth of the stop groove 351 is less than the radius of the positioning ball 230, so that the height of the positioning ball 230 extending into the stop groove 351 is less than half of its own height. When the user needs to rotate the filter element 400 and the filter element seat 300 from the suspended position back to the working position, he only needs to press the filter element 400, which will cause the positioning ball 230 to be pushed out of the stop groove 351 by the arc surface, making the operation more convenient and effortless for the user.

[0046] To limit the movement of the filter element 400 and filter element holder 300 in the working position, this embodiment also provides a limiting groove 352 with the same structure as the stop groove 351 on the rotating part 340. When the filter element holder 300 is flipped to the working position, the positioning spring 220 pushes the positioning ball 230 into the limiting groove 352, so that the filter element holder 300 stays in the working position. The setting of the limiting groove 352 can not only limit the movement of the filter element 400 and filter element holder 300, but also prompt the user with a click sound when the positioning ball 230 is inserted into the limiting groove 352, so as to improve the user experience.

[0047] like Figure 7As shown, a mounting hole 122 is provided on the mounting bracket 100. The mounting hole 122 extends radially along the pivot hole 121 and penetrates the mounting bracket 100, allowing the outside of the pivot hole 121 to communicate with it. The positioning seat 210 passes through the mounting hole 122 and is detachably connected to the mounting bracket 100. This detachable connection structure allows the positioning element 200 to be removed from the mounting bracket 100 and replaced separately if it is damaged, reducing maintenance and replacement costs. Of course, it is understood that in another embodiment, the positioning seat 210 and the mounting bracket 100 can be integrated into one structure, and the opening of the positioning groove 211 can be located on the inner wall of the pivot hole 121 to reduce assembly steps.

[0048] In this embodiment, as Figure 2 As shown, the mounting bracket 100 includes a filter element bracket 110 and a filter element seat bracket 120. A receiving cavity 111 is provided on the filter element bracket 110, and the filter element seat bracket 120 is detachably connected to the top of the filter element bracket 110. A pivot hole 121 is provided on the filter element seat bracket 120. Because the filter element seat bracket 120, which has a pivot hole 121 and is easily damaged, is detachably connected to the filter element bracket 110, when the filter element seat bracket 120 is damaged due to excessive wear, it can be removed and replaced separately from the filter element bracket 110 without replacing or repairing the entire mounting bracket 100, thus reducing maintenance costs.

[0049] In this preferred embodiment, the filter element holder 300 includes a base 310, an inlet pipe 320, and an outlet pipe 330. The inlet pipe 320 and the outlet pipe 330 are located on both sides of the base 310. A rotating part 340 is located on the inlet pipe 320 and the outlet pipe 330. Two filter element holder supports 110 are provided. The rotating parts 340 on the inlet pipe 320 and the outlet pipe 330 are respectively inserted into the pivot holes 121 of the two filter element holder supports 120, so that the filter element holder 300 is rotatably connected to the mounting bracket 100. By providing two filter element supports 110, the force on the filter element holder 300 is more even when rotating, avoiding damage caused by excessive force on one side of the filter element holder 300. By setting the two rotating parts 340 on the inlet pipe 320 and the outlet pipe 330 respectively, the strength of the rotating parts 340 is enhanced while reducing the space occupied by the rotating parts 340, thus reducing the overall volume of the filter element holder 300.

[0050] Example 2:

[0051] The difference between this embodiment and Embodiment 1 is that, in this embodiment, as... Figure 10 As shown, the stop component is a stop rib 353, which is provided on the outer peripheral surface of the rotating part 340 facing the inner wall of the shaft hole 121, as shown. Figure 11As shown, the positioning element is a positioning rib 240, which is located on the inner wall of the rotating shaft hole 121, as shown. Figure 13 As shown, when the filter element and filter element holder 300 are in the working position, the stop rib 353 and the positioning rib 240 are not in contact. During the process of the user flipping the filter element from the working position to the suspended position, the stop rib 353 rotates with the rotating part 340 and passes over the positioning rib 240. The filter element is released when the stop rib 353 has completely passed over the positioning rib 240. Figure 12 As shown, the filter element is in the suspended position at this time. The stop rib 353 abuts against the positioning rib 240 to prevent the rotating part 340 on the filter element seat 300 from freely rotating back to the working position, thus keeping the filter element and filter element seat 300 in the suspended position so that the user can replace the filter element. The filter element can be limited through a simple structure, which improves the user experience and reduces the production and processing costs.

[0052] This implementation also features a limiting rib on the inner wall of the rotating shaft hole. As the user flips the filter element from the suspended position to the working position, the stopping rib passes over the positioning rib and rotates with the rotating part until the stopping rib abuts against the limiting rib. The limiting rib can prevent the filter element seat and filter element from continuing to rotate by abutting against the stopping rib, so that the filter element stays in the working position and reminds the user that the filter element has been installed in place, thus improving the user experience.

[0053] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
