Description

Technical Field

[0001] The utility model relates to the technical field of water purification, in particular to a filter bottle device and a filter bottle assembly. Background Art

[0002] In existing filter bottle devices, the seal is directly positioned between the filter bottle cap and the filter bottle. To ensure an effective seal, the filter bottle cap and filter bottle must remain tightly connected, which greatly complicates their connection and removal. This is especially true when the two are connected via a threaded structure, which requires significant tightening and unscrewing. Disassembly also requires considerable force.

[0003] The existing filter bottle device seal arrangement includes two types: pressure seal and side seal. Figure 1A As shown, seal 31P is configured as a compression seal, while seal 32P is configured as a side seal. It will be appreciated that if compression seal is used, the filter bottle cap 2P and filter bottle 1P must be tightened as tightly as possible to flatten seal 31P and achieve a reliable seal. This inevitably makes it difficult to unscrew the filter bottle cap 2P and filter bottle 1P during disassembly. Furthermore, since the diameter of the annular ring formed by seal 31P is not less than the inner diameter of filter bottle 1P, i.e., seal 31P is relatively large, the friction caused by seal 31P when filter bottle cap 2P and filter bottle 1P rotate relative to each other is significant, further hindering the tightening and unscrewing processes of filter bottle cap 2P and filter bottle 1P. Correspondingly, if sealing is performed using a side seal, although the degree of tightening of the filter bottle cap 2P and the filter bottle 1P can be slightly reduced, the seal 32P also has a larger size, which will also cause greater friction, thereby causing greater obstacles to the tightening and unscrewing processes of the filter bottle cap 2P and the filter bottle 1P.

[0004] Furthermore, since the filter bottle 1P and filter bottle cap 2P are typically made of plastic, and the filter bottle cap 2P is not a regular cylindrical shape, a high degree of roundness cannot be guaranteed. Furthermore, since the filter bottle 1P wall lacks lateral (radial) support from within the filter bottle 1P, the filter bottle 1P and / or filter bottle cap 2P are easily deformed during tightening. This forces filter bottle manufacturers to select seals with a large compression capacity when selecting seals to compensate for the sealing difficulties caused by plastic deformation. However, when replacing the filter element of the filter bottle device, the seal also needs to be replaced. This large compression capacity makes it difficult for the seal to rebound. If the seal is continued to be used, the effectiveness and reliability of the seal cannot be guaranteed.

[0005] Moreover, during the tightening process of the filter bottle cap 2P and the filter bottle 1P, they move relative to each other (for example, one moves clockwise and the other moves counterclockwise). Neither the seal 31P nor the seal 32P can rotate with the filter bottle cap 2P or the filter bottle 1P, which causes the seal to be easily twisted after the filter bottle cap 2P and the filter bottle 1P are tightened, resulting in seal failure and water leakage. Summary of the Invention

[0006] The main advantage of the present invention is that it provides a filter bottle device, which includes a sealing member that can rotate relative to the filter bottle cap, and is sealed with the filter bottle by the sealing member, thereby replacing the traditional sealing method of directly providing a sealing member between the filter bottle cap and the filter bottle. Moreover, during the process of tightening and unscrewing the filter bottle cap and the filter bottle, the sealing member basically does not rotate relative to the filter bottle, which can greatly reduce the difficulty of tightening and unscrewing the filter bottle cap and the filter bottle. In other words, the present invention creatively proposes to separate the "fixing" and "sealing" between the filter bottle cap and the filter bottle as much as possible, and use the sealing member to replace the filter bottle cap to assume the "sealing" function, making it easier to tighten and unscrew the filter bottle cap and the filter bottle.

[0007] Another advantage of the present invention is that it provides a filter bottle device in which the sealing member can provide transverse (radial) support to the bottle wall of the filter bottle from the inside of the filter bottle, resulting in greater structural stability. The sealing member is easier to form and maintain a higher degree of roundness than the filter bottle cap, thereby allowing the sealing member and the filter bottle to be used with a seal having a smaller compression than traditional sealing methods, thereby allowing the seal to be used multiple times without having to be replaced every time the filter element is replaced. Moreover, the seal having a smaller compression also reduces the obstruction when the sealing member and the filter bottle undergo relative translation, which helps to further reduce the difficulty of tightening and unscrewing the filter bottle cap and the filter bottle.

[0008] Another advantage of the present invention is that it provides a filter bottle device, wherein during the process of tightening and unscrewing the filter bottle cover and the filter bottle, the sealing member can basically not rotate relative to the filter bottle, so that the seal between the sealing member and the filter bottle is less likely to be twisted, which can reduce the risk of sealing failure and water leakage.

[0009] Accordingly, according to an embodiment of the present invention, a filter bottle device having at least one of the aforementioned advantages includes:

[0010] A filter bottle comprising a housing;

[0011] filter element;

[0012] filter bottle cap;

[0014] The first sealing member, wherein the shell includes an open end and an extension portion extending from the open end, wherein the shell has a accommodating cavity, the filter element is arranged in the accommodating cavity, and the accommodating cavity has a mounting opening formed at the open end of the shell, wherein the filter bottle cover is suitable for being detachably arranged on the outer side wall of the open end of the shell, the sealing member is movably arranged on the inner side wall of the open end of the shell, and the first sealing member is arranged between the inner side wall of the open end of the shell and the sealing member, wherein when the filter bottle cover is arranged on the outer side wall of the open end of the shell, the filter bottle cover can be pressed against the top end of the sealing member.

[0015] According to another aspect of the present invention, the present invention provides a filter bottle assembly, comprising:

[0016] A filter bottle comprising a housing;

[0017] filter bottle cap;

[0018] Packers; and

[0019] A first sealing member, wherein the shell includes an open end and an extension portion extending from the open end, wherein the shell has a accommodating cavity, and the accommodating cavity has a mounting opening formed at the open end of the shell, wherein the filter bottle cover is suitable for being detachably arranged on the outer side wall of the open end of the shell, and the sealing member is movably arranged on the inner side wall of the open end of the shell, and the first sealing member is arranged between the inner side wall and the sealing member, wherein when the filter bottle cover is arranged on the outer side wall of the open end of the shell, the filter bottle cover can be pressed against the top end of the sealing member.

Other obvious replacements, modifications, and variations may occur to those skilled in the art. Therefore, the scope of protection of the present invention should not be limited to the exemplary embodiments described herein.

[0043] Those skilled in the art should understand that, unless otherwise specified herein, the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple.

[0044] Those skilled in the art should understand that, unless otherwise specified herein, the directions or positions referred to by terms such as "longitudinal," "transverse," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" are based on the directions or positions shown in the accompanying drawings and are merely for the purpose of facilitating the description of the present invention. They do not indicate or imply that the devices or components involved must have a specific direction or position. Therefore, the above terms should not be construed as limiting the present invention.

[0045] Refer to the attached drawings of this utility model specification Figures 1B to 4BAs shown, a filter bottle device according to an embodiment of the present invention is illustrated, which includes a filter bottle 1, a filter element 12, a filter bottle cover 2, a sealing member 3 and a first sealing member 51, wherein the filter bottle 1 includes a shell 11, the shell 11 includes an open end 111 and an extension 112 extending from the open end, wherein the shell 11 has a accommodating cavity 110, the filter element 12 is arranged in the accommodating cavity 110, and the accommodating cavity 110 has a mounting opening 1101 formed at the open end 111 of the shell 11, wherein the filter bottle cover 2 is suitable for being detachably arranged on the outer side wall 1111 of the open end 111 of the shell 11 of the filter bottle 1, and the sealing member 3 is provided. The filter element 12 and the housing 11 are movably mounted on the inner sidewall 1112 of the open end 111 of the filter bottle 1. The first sealing member 51 is disposed between the inner sidewall 1112 of the filter bottle 1 and the sealing member 3. When the filter bottle cap 2 is disposed on the outer sidewall 1111 of the open end 111 of the housing 11 of the filter bottle 1, the filter bottle cap 2 can press against the top end 31 of the sealing member 3. Thus, when the filter bottle cap 2 is fastened to the outer sidewall 1111 of the open end 111 of the housing 11 of the filter bottle 1, the filter bottle cap 2 can press and drive the sealing member 3 to move relative to the open end 111 of the housing 11 of the filter bottle 1. Preferably, the filter element 12 and the housing 11 form a water cavity 120 therebetween.

[0046] In order to more significantly reflect the advantages of the present invention, the present invention is illustrated by taking the filter bottle cover 2 and the filter bottle 1 as an example of a rotationally detachable connection. For example, the filter bottle cover 2 and the filter bottle 1 are rotationally detachably connected by a threaded structure, or by a rotating snap-fit structure. It is understandable that the filter bottle cover 2 and the filter bottle 1 can also be detachably connected by a clamp or other appropriate means. Specifically, when the filter bottle cover 2 is screwed onto the outer side wall 1111 of the open end 111 of the shell 11 of the filter bottle 1, the filter bottle cover 2 rotates relative to the filter bottle 1 and moves toward the extension 112 of the shell 11, so that the filter bottle cover 2 can compress and drive the sealing member 3 to move relative to the open end 111 of the shell 11 of the filter bottle 1 and toward the extension 112 of the shell 11. Accordingly, during this process, the torque of the rotational friction force (driving force) applied by the filter bottle cover 2 to the top end 31 of the sealing member 3 is smaller than the torque of the first sealing member 51 between the inner side wall 1112 of the filter bottle 1 and the sealing member 3 to the rotation, so that the filter bottle cover 2 is basically unable to drive the sealing member 3 to rotate. Therefore, the sealing member 3 basically does not rotate relative to the inner side wall 1112 of the open end 111 of the shell 11 of the filter bottle 1, and only translates relative to the inner side wall 1112 of the open end 111 of the shell 11 of the filter bottle 1, thereby basically eliminating the obstruction of the large-size seal to the relative rotation of the filter bottle cover 2 and the filter bottle 1, and can greatly reduce the difficulty of tightening the filter bottle cover 2 and the filter bottle 1. When tightening the filter bottle cap 2, there's no need to tighten forcefully. Simply rotate it to a predetermined position to ensure the septum 3 is inserted to a certain depth into the open end 111 of the housing 11 of the filter bottle 1. Relative rotation between the two is largely unimpeded by the large seal, allowing for easy rotation. Accordingly, unscrewing (or removing) the filter bottle cap 2 from the outer sidewall 1111 of the open end 111 of the housing 11 of the filter bottle 1 is also relatively easy. In other words, the present invention creatively separates the "fixing" and "sealing" functions between the filter bottle cap 2 and the filter bottle 1 as much as possible, utilizing the septum 3 to replace the "sealing" function of the filter bottle cap 2, making it easier to tighten and unscrew the filter bottle cap 2 and the filter bottle 1. Furthermore, since the septum 3 can essentially not rotate relative to the filter bottle 1, the first seal 51 is less likely to twist, reducing the risk of seal failure and water leakage.

[0047] It will be appreciated that the septum 3 is configured to provide lateral (radial) support to the open end 111 (the wall of the open end 111) of the housing 11 of the filter bottle 1 from within the housing 11 of the filter bottle 1, such as by transmitting force through the first seal 51. This not only enhances structural stability but also helps ensure an effective seal. Furthermore, the septum 3 is easier to form and maintain a higher degree of roundness than the filter bottle cap 2, allowing the use of a seal with less compression than traditional sealing methods between the septum 3 and the filter bottle 1. This allows the first seal 51 to be used multiple times, eliminating the need to replace it each time the filter cartridge is replaced. Furthermore, the first seal 51 with less compression also minimizes the obstruction during relative translation between the septum 3 and the filter bottle 1, further simplifying the tightening and unscrewing of the filter bottle cap 2 and the filter bottle 1.

[0048] As shown in the attached figure Figures 1B to 4B As shown, the filter bottle cover 2 includes an opening portion 21 and a connecting portion 22 extending from the opening portion 21, and the sealing member 3 includes the top end 31, a mounting end 32 and a conducting portion 33, wherein the mounting end 32 and the conducting portion 33 extend integrally from two opposite sides of the top end 31, respectively, wherein the opening portion 21 forms a through opening 210, and the conducting portion 33 forms a conducting channel 330, wherein the conducting channel 330 is suitable for communicating with the water cavity 120 or the filter element 12, and the conducting portion 33 passes through the through opening 210 of the opening portion 21. Preferably, the top end 31 and the mounting end 32 are arranged to form a conducting cavity 320, wherein the conducting cavity 320 is suitable for communicating with the conducting channel 330 and the water cavity 120 or the filter element 12, respectively, and the conducting portion 33 passes through the through opening 210 of the opening portion 21. It can be understood that, as shown in the accompanying drawings Figure 2AAs shown, when the filter bottle device has three openings, the filter bottle 1 further includes a first fluid channel 1121 and a second fluid channel 1122, the extension portion 112 of the shell 11 has a lower end portion 1120, and the first fluid channel 1121 and the second fluid channel 1122 of the filter bottle 1 are respectively arranged at the lower end portion 1120 of the filter bottle 1, wherein the first fluid channel 1121 is formed in a central area 11201 of the lower end portion 1120, and the second fluid channel 1122 is formed in an edge area 11202 extending outward from the central area 11201 of the lower end portion 1120. It can be understood that the filter element 12 can be a reverse osmosis membrane filter element or a three-port ultrafiltration membrane filter element. For example, when the filter element 12 is a reverse osmosis membrane filter element, the water chamber 120 is divided into a first water chamber 1201 and a second water chamber 1202 by the sealing component 121 of the filter element 12, wherein the first water chamber 1201 is connected to the conduction chamber 320, and the second water chamber 1202 is connected to the second fluid channel 1122. The water inlet end of the filter element 12 is connected to the first water chamber 1201 (or the conduction chamber 320), and the sewage discharge end of the filter element 12 is connected to the second water chamber 1202. The purified water of the filter element 12 The outlet is sealed and connected to the first fluid channel 1121. Taking the conducting channel 330 as the inflow channel of raw water, the first fluid channel 1121 as the outflow channel of purified water, and the second fluid channel 1122 as the outflow channel of sewage as an example, raw water flows in from the conducting channel 330, passes through the conducting cavity 320, and flows into the water inlet end of the filter element 12. The purified water purified by the filter element 12 is discharged from the purified water outlet and finally flows out through the first fluid channel 1121. The sewage flows into the second water cavity 1202 through the sewage discharge end of the filter element 12 and is then discharged through the second fluid channel 1122. It can be understood that the conducting channel 330, the first fluid channel 1121 and the second fluid channel 1122 can form threaded openings, or can form quick-connect interfaces as needed. It can be understood that, as shown in the accompanying drawings Figure 2C As shown, when the filter bottle 1 is a two-port filter bottle, when the conducting cavity 320 of the sealing member 3 is connected to the conducting channel 330 and the water cavity 120 respectively, the raw water can flow from the conducting channel 330 to the water cavity 120, and after being purified by the filter element 12, it flows out from the clean water port of the filter element 12 and the first fluid channel 1121. It can be understood that, as shown in the accompanying drawings, Figure 2D As shown, when the conducting channel 330 of the sealing member 3 is connected to the filter element 12 (or the opening of the filter element 12), raw water can flow from the first fluid channel 1121 into the water cavity 120 and flow to the filter element 12. After being purified by the filter element 12, the purified water flows out from the conducting channel 330.

[0049] As shown in the attached figure Figures 1B to 4B As shown, the mounting end 32 of the sealing member 3 includes a main body 321 and a sealing portion 322 extending outward from the main body 321, wherein the first sealing member 51 is disposed between the sealing portion 322 and the inner sidewall 1112 of the open end 111 of the housing 11 of the filter bottle 1. Preferably, the mounting end 32 is flared along its extension direction, so that the sealing member 3 is more likely to move inward relative to the inner sidewall 1112 of the open end 111 of the housing 11 when pressed and driven by the filter bottle cover 2, and is more likely to position the filter element 12 and avoid contact with the filter element 12.

[0050] As shown in the attached figure Figures 1B to 4B As shown, the filter bottle device further includes a limiting member 9, and the sealing member 3 further includes a limiting portion 34, wherein the limiting portion 34 extends outward from the conducting portion 33, and the limiting member 9 is suitable for being arranged between the limiting portion 34 and the opening portion 21 of the filter bottle cover 2, so that the filter bottle cover 2 and the sealing member 3 cannot move relative to each other and can form a relative rotation with less resistance. When the filter bottle cover 2 is unscrewed (or unscrewed) from the outer side wall 1111 of the open end 111 of the shell 11 of the filter bottle 1, the sealing member 3 is restricted by the limiting member 9 to the opening portion 21 of the filter bottle cover 2, and the torque of the rotational friction force (driving force) applied by the limiting member 9 and the opening portion 21 of the filter bottle cover 2 to the sealing member 3 is much smaller than the torque of the resistance force of the relative rotation of the first sealing member 51 between the inner side wall 1112 of the filter bottle 1 and the sealing member 3, so that the filter bottle cover 2 is basically unable to drive the sealing member 3 to rotate. Therefore, the sealing member 3 basically does not rotate relative to the inner side wall 1112 of the open end 111 of the shell 11 of the filter bottle 1, and only translates relative to the inner side wall 1112 of the open end 111 of the shell 11 of the filter bottle 1 (the sealing member 3 moves in the direction away from the extending portion 112 of the shell 11). The limiting member 9 is, for example, in the form of a retaining spring, but may also be in the form of a nut or other retaining means, for example, a nut fixed to the retaining portion 34 of the sealing member 3. It is understood that in order to better ensure the sealing performance of the filter bottle device, the first sealing member 51 is often replaced when the filter element 12 is replaced. The limiting member 9 in the form of a retaining spring allows the sealing member 3 to be easily removed from the filter bottle cover 2 after the retaining spring is removed, and the first sealing member 51 provided on the sealing member 3 can be further replaced.

[0051] As shown in the attached figure Figures 1B to 4BAs shown, the filter bottle device further includes at least one locking unit 7, wherein the locking unit 7 includes a first locking member 71, a second locking member 72 and a locking plug-in 73, wherein the first locking member 71 is arranged on the outer wall of the filter bottle 1, and the second locking member 72 is arranged on the outer wall of the filter bottle cover 2, and when the first locking member 71 and the second locking member 72 are aligned, a positioning slot 710 can be formed, wherein the locking plug-in 73 is configured to be inserted into the positioning slot 710 to keep the first locking member 71 and the second locking member 72 in a locked position. It can be understood that the filter bottle device is configured so that when the filter bottle cover 2 is rotated to the point where the first locking member 71 and the second locking member 72 are connected and aligned, the filter bottle cover 2 is screwed into the preset position of the filter bottle 1 to ensure that the sealing member 3 is inserted into the filter bottle 1 to a certain depth. At this time, the locking plug-in 73 is inserted into the positioning slot 710 to keep the first locking member 71 and the second locking member 72 in the locked position, and keep the filter bottle cover 2 screwed into the preset position. It can be understood that when the filter bottle cover 2 is screwed into the preset position of the filter bottle 1, since the locking unit 7 has an anti-loosening effect, the threads of the filter bottle cover 2 and the filter bottle 1 do not need to be tightened so that they can be easily unscrewed in the future, because excessive tightening will make it difficult to unscrew. In particular, when the filter bottle cover 2 and the filter bottle 1 are made of plastic material, they will be continuously subjected to water pressure during the operation of the filter bottle device, and the filter bottle cover 2 and the filter bottle 1 will be deformed and meshed together, making it difficult to unscrew them easily.

[0052] Attached Figures 5 to 7BThe figure shows an optional implementation of the filter bottle device according to an embodiment of the present invention, which includes a filter bottle 1, a filter element 12, a filter bottle cover 2, a sealing member 3A and a first sealing member 51, wherein the filter bottle 1 includes a shell 11, the shell 11 includes an open end 111 and an extension 112 extending from the open end 111, wherein the shell 11 has a accommodating cavity 110, the filter element 12 is disposed in the accommodating cavity 110, and the accommodating cavity 110 has a mounting opening 1101 formed at the open end 111 of the shell 11, wherein the filter bottle cover 2 is adapted to be detachably disposed on the outer side wall 1111 of the open end 111 of the shell 11 of the filter bottle 1, The sealing member 3A is movably disposed on the inner sidewall 1112 of the open end 111 of the housing 11, and the first sealing member 51 is disposed between the inner sidewall 1112 of the filter bottle 1 and the sealing member 3A. When the filter bottle cap 2 is disposed on the outer sidewall 1111 of the open end 111 of the housing 11 of the filter bottle 1, the filter bottle cap 2 can press against the top end 31 of the sealing member 3A, so that when the filter bottle cap 2 is tightened against the outer sidewall 1111 of the open end 111 of the housing 11 of the filter bottle 1, the filter bottle cap 2 can press and drive the sealing member 3A to move relative to the open end 111 of the housing 11 of the filter bottle 1. Preferably, the filter element 12 and the housing 11 form a water cavity 120 therebetween.

[0053] As shown in the attached figure Figures 5 to 7B As shown, the filter bottle device further includes a limiting member 9, the filter bottle cover 2 includes an opening portion 21 and a connecting portion 22 extending from the opening portion 21, and the sealing member 3A includes the top end 31, a mounting end 32, a positioning portion 33A and a limiting portion 34A, wherein the mounting end 32 and the positioning portion 33A extend integrally from two opposite sides of the top end 31, and the limiting portion 34A extends outward from the positioning portion 33A, wherein the opening portion 21 forms a through opening 210, and the positioning portion 33A passes through the through opening 210 of the opening portion 21, and the limiting member 9 is suitable for being arranged between the limiting portion 34A and the opening portion 21 of the filter bottle cover 2, so that the filter bottle cover 2 and the sealing member 3A cannot move relative to each other and can form relative rotation with less resistance. It can be understood that Figures 5 to 7BThe water inlet and outlet of the filter bottle device shown are both located at one end of the filter bottle device away from the filter bottle cover 2. The limiting member 9 is, for example, a retaining spring, but may also be a nut or other retaining member, such as a nut secured to the retaining portion 34A of the sealing member 3A. It will be appreciated that to better ensure the sealing performance of the filter bottle device, the first sealing member 51 is often replaced when the filter element 12 is replaced. The retaining spring-type limiting member 9 facilitates removal of the sealing member 3A from the filter bottle cover 2 after the retaining spring is removed, allowing for further replacement of the first sealing member 51 disposed on the sealing member 3A.
