Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter bottle technology for water purifiers, and in particular to a filter bottle structure for water purifiers. Background Technology
[0002] Currently, water is an indispensable resource in daily life, and its cleanliness is directly related to people's health. In some areas with poor water quality, although tap water undergoes preliminary disinfection before being introduced into homes, it may still be contaminated during transportation. Therefore, using a water purifier to further treat tap water is particularly important. Existing filter bottles typically use a threaded connection between the cap and body, but this connection rotation process takes a considerable amount of time, making quick assembly and disassembly inconvenient. While some water purification filter bottles use a rotary snap-fit design for quick assembly and disassembly, this design lacks a limiting structure and the fit is not tight enough. After prolonged use, it is prone to loosening or detachment, leading to leaks at the connection gap between the cap and body. The stability and reliability of the connection structure are poor. Utility Model Content
[0003] The purpose of this invention is to provide a filter bottle structure for water purifiers, aiming to solve the technical problem of poor stability and reliability of filter bottle connection structures in the prior art.
[0004] To achieve the above objectives, the present invention provides a filter bottle structure for a water purifier, comprising:
[0005] The bottle cap has a plurality of first snap-fit blocks spaced circumferentially on the inner wall of the cap opening. Each of the plurality of first snap-fit blocks has a locking groove. The bottom of the locking groove has a first abutting surface. The first abutting surface is an inclined surface that extends at an angle so that the plane on which the first abutting surface is located is set at a first angle with the horizontal plane. One end of the locking groove is open. The height of the first end of the first abutting surface near the opening relative to the horizontal plane is higher than the height of the second end of the first abutting surface away from the opening.
[0006] The bottle body has multiple second locking blocks spaced circumferentially on the outer wall of the bottle mouth. Each of the second locking blocks has a second abutment surface at its bottom. The plane of the second abutment surface is set at a second angle with the horizontal plane so that the second locking block can be inserted into the locking groove through the opening, so that the first abutment surface abuts against the second abutment surface, thereby realizing the locking connection between the bottle cap and the bottle body. Furthermore, the height of the end of the second abutment surface that abuts against the first end of the first abutment surface relative to the horizontal plane is higher than the height of the end of the second abutment surface that abuts against the second end of the first abutment surface.
[0007] As one of the preferred solutions, the degree of the first included angle is set as a, where a is greater than 0 and less than or equal to 15 degrees, and the degree of the second included angle is set as b, where b is greater than 0 and less than or equal to 15 degrees.
[0008] As one of the preferred solutions, the first snap-fit block has a first guide slope at one end near the opening, and the second snap-fit block has a second guide slope, so that the second snap-fit block can be rotated and snapped into the locking groove by cooperating with the first guide slope through the second guide slope.
[0009] As one of the preferred embodiments, the inner wall of the bottle cap opening is also provided with multiple insertion ports, each of the insertion ports being located between two adjacent first locking blocks. The insertion ports are correspondingly connected to the openings of the locking slots, so that each of the second locking blocks is sequentially rotated and locked into each of the locking slots through the insertion ports and the openings.
[0010] As a preferred embodiment, the bottle cap opening is also provided with a marking structure to mark and guide the position of each of the first snap-fit blocks, thereby facilitating the quick and easy screwing of each of the second snap-fit blocks into the corresponding locking slots through the insertion port.
[0011] As one preferred embodiment, the marking structure is formed by a plurality of first snap-fit blocks protruding downward relative to the edge of the cap opening.
[0012] As one of the preferred solutions, a first abutting wall is provided on the top of the first snap-fit block, and the first abutting wall is formed by the inner wall of the bottle cap protruding and extending along the central axis of the bottle cap.
[0013] As one of the preferred solutions, the other end of the locking groove is provided with a stop portion, which abuts against the second locking block to limit the movement.
[0014] As a preferred embodiment, an elastic washer is fitted at the bottle opening of the bottle body, so that when the bottle cap is connected to the bottle body, the elastic washer abuts against the inner wall of the bottle cap, thereby sealing the bottle cap and the bottle body; and / or
[0015] The blocking part is provided with a first inclined surface on one side near the second locking block, and the first inclined surface abuts against the second guide inclined surface of the second locking block to limit the movement.
[0016] As a preferred embodiment, the system further includes a filter cartridge assembly disposed within the bottle body. The filter cartridge assembly has a filter cylinder structure and a hollow cavity is formed inside the filter cartridge assembly. The bottle cap has an inlet and an outlet. The outlet communicates with the inner cavity of the bottle body, and the inlet communicates with the hollow cavity of the filter cartridge assembly, so that the raw water from the inlet flows into the hollow cavity of the filter cartridge assembly, and the purified water obtained after being filtered from the inside to the outside by the filter cartridge assembly flows into the inner cavity of the bottle body and is discharged through the outlet.
[0017] As can be seen from the above technical solution, the filter bottle structure for water purifiers of this utility model uses a second locking block to rotate and engage with the locking groove of the first locking block, thereby enabling the bottle cap and bottle body to be connected by a rotating snap-fit. This allows for quick disassembly and assembly. Furthermore, the first abutting surface of the first locking block abuts against the second abutting surface of the second locking block for limiting the engagement. Both the first and second abutting surfaces are inclined, so that the height of the adjacent ends of the first and second abutting surfaces near the opening is higher than the height of the adjacent ends of the first and second abutting surfaces away from the opening. This, to a certain extent, limits the second locking block from accidentally detaching from the opening of the locking groove, thereby improving the stability and reliability of the connection structure between the bottle cap and the bottle body, increasing the service life of the filter bottle product, facilitating user use, and providing a better user experience.

[0031] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0032] Please refer to the following: Figures 1 to 8This utility model provides a filter bottle structure for a water purifier, including a bottle cap 100 and a bottle body 200. The inner wall of the cap 100 is provided with a plurality of first locking blocks 110 spaced circumferentially. Each of the first locking blocks 110 has a locking groove 120. The bottom of the locking groove 120 has a first abutment surface 111, which is an inclined surface extending at an angle so that the plane containing the first abutment surface 111 forms a first angle with the horizontal plane. One end of the locking groove 120 is an opening 121. The height of the first end of the first abutment surface 111 near the opening 121 relative to the horizontal plane is higher than the height of the second end of the first abutment surface 111 away from the opening 121. The bottle body 200 has a plurality of second locking blocks 210 spaced circumferentially on the outer wall of the bottle mouth. The bottom of each of the plurality of second locking blocks 210 is provided with a second abutting surface 211. The plane where the second abutting surface 211 is located is set at a second angle with the horizontal plane so that the second locking block 210 can be inserted into the locking groove 120 through the opening 121, so that the first abutting surface 111 abuts against the second abutting surface 211, thereby realizing the locking connection between the bottle cap 100 and the bottle body 200. The height of the end of the second abutting surface 211 that abuts against the first end of the first abutting surface 111 relative to the horizontal plane is higher than the height of the end of the second abutting surface 211 that abuts against the second end of the first abutting surface 111.
[0033] The bottle body 200 also contains a filter element assembly 300 for filtering tap water. The water level 400 is parallel to the water surface. The specific structure of the filter element assembly 300 is existing technology and will not be described in detail here.
[0034] As can be seen, the filter bottle structure for water purifiers of this utility model uses the second locking block 210 to rotate and engage with the locking groove 120 of the first locking block 110, thereby enabling the bottle cap 100 and the bottle body 200 to be connected by a rotating snap-fit. This allows for quick disassembly and assembly. Furthermore, the first abutting surface 112 of the first locking block 110 and the second abutting surface 212 of the second locking block 210 abut against each other for limiting the engagement. Both the first abutting surface 112 and the second abutting surface 212 are inclined, so that the height of the adjacent ends of the first abutting surface 112 and the second abutting surface 212 near the opening 121 is higher than the height of the adjacent ends of the first abutting surface 112 and the second abutting surface 212 away from the opening 121. This, to a certain extent, limits the second locking block 210 from accidentally detaching from the opening 121 of the locking groove 120, thereby improving the stability and reliability of the connection structure between the bottle cap 100 and the bottle body 200, increasing the service life of the filter bottle, facilitating user use, and providing a better user experience.
[0035] In this embodiment, the degree of the first included angle is set as 'a', where 'a' is greater than 0 and less than or equal to 15 degrees, and the degree of the second included angle is set as 'b', where 'b' is greater than 0 and less than or equal to 15 degrees. The degree of both the first and second included angles should not be too large. If the degree is too large, the bottle cap 100 will be difficult to remove when it is placed on the bottle body 200. Therefore, the degree of both the first and second included angles is preferably 8 degrees. This design ensures that when the second locking block 210 is engaged in the locking groove 120, it hooks onto the locking groove 120, preventing it from sliding out when no one is operating it. Simultaneously, it prevents the second locking block 210 from being locked too tightly in the locking groove 120, making it difficult to open the bottle cap 100 again. The connection structure is stable, and the user finds it simple and convenient to use.
[0036] Furthermore, the first latching block 110 has a first guide slope 112 at one end near the opening 121, and the second latching block 210 has a second guide slope 212. The second guide slope 212 engages with the first guide slope 112 to guide the second latching block 210 to rotate and latch into the locking groove 120. This arrangement facilitates the engagement of the second latching block 210 with the first guide slope 112 and the second guide slope 212, allowing the second latching block 210 to easily and quickly latch into the locking groove 120, thus simplifying user operation and use.
[0037] Furthermore, the inner wall of the cap 100 is provided with multiple insertion ports 130, each insertion port 130 being located between two adjacent first locking blocks 110. The insertion ports 130 are correspondingly connected to the openings 121 of the locking grooves 120, allowing each second locking block 210 to be sequentially rotated and locked into its respective locking groove 120 through the insertion ports 130 and openings 121. Specifically, when connecting the cap 100 of the filter bottle to the body 200 of the filter bottle, the second locking block 210 is first inserted into the insertion port 130, and then the cap 100 and the body 200 of the filter bottle are rotated relative to each other, thereby causing the second locking block 210 to engage in the locking groove 120. This connection structure is relatively simple and convenient for user operation.
[0038] Furthermore, the cap 100 is also provided with a marking structure 113 to mark and guide the position of each first locking block 110, thereby facilitating the quick and easy screwing of each second locking block 210 into the corresponding locking slot 120 through the insertion port 130. This design reduces the time required for the user to align the second locking block 210 with the insertion port 130, making the operation more convenient and further increasing the practicality and reliability of the product.
[0039] Furthermore, the marking structure 113 is formed by a plurality of first snap-fit blocks 110 extending downward relative to the edge of the cap 100. The marking structure 113 is formed by the first snap-fit blocks 110. This arrangement reduces the product's processing cost, increases the stability of the product structure, further improves the product's reliability and usability, and provides a better user experience.
[0040] Furthermore, a first abutment wall 140 is provided on the top of the first latching block 110. The first abutment wall 140 is formed by protruding from the inner wall of the bottle cap 100 along the central axis of the bottle cap 100. The first abutment wall 140 is used to abut against the bottle mouth of the bottle body 200 to prevent water leakage when the bottle cap 100 of the filter bottle is connected to the bottle mouth. The first abutment wall 140 is formed by protruding from the inner wall of the bottle cap 100, which makes the structure more stable and reliable, further enhancing the practicality and reliability of the product structure.
[0041] Furthermore, a stop 114 is provided at the other end of the locking groove 120 to limit the movement of the second locking block 210 by abutting against it. The stop 114 facilitates indication of the progress of the second locking block 210 being rotated into the locking groove 120. When the stop 114 abuts against the second locking block 210, it indicates that the bottle cap and bottle body of the filter bottle are connected. At the same time, the stop 114 prevents excessive rotational force when the second locking block 210 is rotated into the locking groove 120, which could cause the second locking block 210 to detach from the end of the locking groove 120 away from the opening 121, further improving the reliability of the product.
[0042] In this embodiment, an elastic washer 220 is fitted at the bottle mouth of the bottle body 200 so that when the bottle cap 100 is connected to the bottle body 200, the bottle body 200 abuts against the first abutment wall 140 through the elastic washer 220, thereby sealing the bottle cap 100 and the bottle body 200. The side of the abutment part 114 near the second locking block 210 is set with a first inclined surface, and the first inclined surface abuts against the second guide inclined surface 212 of the second locking block 210 to limit the movement. The setting of the elastic washer 220 further ensures that there will be no leakage when the bottle cap 100 is connected to the bottle body 200, further enhancing the safety and reliability of the product. The side of the abutment part 114 near the second locking block 210 is set with a first inclined surface, and the abutment part 114 is adapted to the second guide inclined surface 212 of the second locking block 210, making it easier for the second locking block 210 to be accommodated in the locking groove 120.
[0043] In one embodiment, an elastic gasket 220 is fitted at the mouth of the bottle body 200 so that when the bottle cap 100 is connected to the bottle body 200, the bottle body 200 abuts against the first abutment wall 140 through the elastic gasket 220, thereby sealing the bottle cap 100 and the bottle body 200 together. The elastic gasket 220 further ensures that there will be no leakage when the bottle cap 100 is connected to the bottle body 200, further enhancing the safety and reliability of the product.
[0044] Furthermore, the elastic washer 220 is a rubber washer. Using a rubber washer can further reduce processing costs and facilitate industrial processing and production.
[0045] In this embodiment, the filter bottle structure also includes a filter element assembly 300 disposed within the bottle body 200. The filter element assembly 300 has a filter cartridge structure and a hollow cavity is formed inside the filter element assembly 300. The bottle cap 100 has an inlet and an outlet. The outlet communicates with the inner cavity of the bottle body 200, and the inlet communicates with the hollow cavity of the filter element assembly 300, so that the raw water from the inlet flows into the hollow cavity of the filter element assembly 300, and the purified water obtained after being filtered from the inside to the outside by the filter element assembly 300 flows into the inner cavity of the bottle body 200 and is discharged through the outlet. Of course, the filtration principle and specific structure are existing technologies of water purifiers and will not be described in detail here.
[0046] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0047] The filter bottle structure for a water purifier of this utility model uses a second locking block 210 to rotate and engage with the locking groove 120 of the first locking block 110, thereby enabling the bottle cap 100 and the bottle body 200 to be rotatably and snapped together. This allows for quick disassembly and assembly. Furthermore, the first abutting surface 112 of the first locking block 110 and the second abutting surface 212 of the second locking block 210 abut against each other for limiting their engagement. Both the first abutting surface 112 and the second abutting surface 212 are inclined, ensuring that the height of the adjacent ends of the first abutting surface 112 and the second abutting surface 212 near the opening 121 is higher than the height of the adjacent ends of the first abutting surface 112 and the second abutting surface 212 away from the opening 121. This, to a certain extent, limits the second locking block 210 from accidentally detaching from the opening 121 of the locking groove 120, thereby improving the stability and reliability of the connection structure between the bottle cap 100 and the bottle body 200, increasing the service life of the filter bottle, and providing a more convenient and user-friendly experience.
