Description
The prior application: water purifier with U-shaped shell and built-in vertical filter liner cavity with swing shaft
Prior application No.: 201610129119.8
Technical Field
The invention relates to the water treatment industry, in particular to the aspects of deep filtration and purification of drinking water.
Background
The horizontal water purifier can be placed on the table board of a kitchen cabinet or in the cabinet, and the machine is directly placed on the use position without punching and hanging, so that the horizontal water purifier is very convenient to use. Because the filter liner is positioned above the machine base, the filter liner is convenient to replace, and time and labor are saved relatively. However, the biggest problem of adopting the seat type water purifier structure is that the operation surface of the machine is small, the display window and the operation control device can only be arranged on the side vertical surface of the machine, and the top surface is used for replacing the filter container, so that parts can be placed everywhere. Since the water purifier has limited length and width dimensions, generally less than 520 mm × 200 mm × 450 mm, the installation of the display control device on the side vertical surface of the machine will affect the number of the filter cartridges. When the closed filter container is used, the water port of the filter container faces downwards, so that water in the filter container can flow out from the water port of the filter container to pollute the surrounding environment during replacement. The water in the front and back filter containers is discharged from the inlet and outlet pipes of the corresponding base until the water level in the water purifier is balanced, so that the water purifier with the base has the advantage of easy extraction of the filter containers. When the internal filter container of the open type filter cartridge is used, the internal filter container in the existing open type filter cartridge is poured out together with water after the filter cartridge is detached, and the operation is very troublesome, so that the case of cleaning the inner cavity of the filter cartridge is very rare. And because the environment for placing the water purifier is poor, the water flow speed leaking in the process of replacing the filter liner is too fast to be removed easily, thus not only causing inconvenient operation, but also causing the cabinet to be soaked and even damaging the cabinet plate. In view of the whole process that the filter container is always replaced along with the use of the water purifier, the related problems caused by replacing the filter container and cleaning the filter channel can be frequently repeated. In addition, the scaling phenomenon of the filter cartridge and the inner wall of the pipeline of the water purifier is very serious after the water purifier is used for a long time, and the water purifying treatment environment of the water purifier is increasingly poor. Especially, the problems of cleaning the inner cavity of the upper open type filter cylinder, discharging sewage containing a large amount of impurities and extracting the built-in filter liner are not solved, so that a machine model of a lower machine base is rarely adopted. Even, no water purifier capable of cleaning the filter cartridge is available so far. On the other hand, the filter liner replacement and cleaning maintenance of the water purifier require professional personnel to go to the home for service, and the professional personnel are reluctant to provide the home cleaning service due to the lack of cleaning means, labor and time, so that the problem of machine cleaning is rarely mentioned to users. So that most users only know to replace the filter cartridge, but few know to regularly clean the machine. In addition, the waste of water resource is very serious to current nanofiltration membrane and reverse osmosis membrane purifier. Typically, the "concentrate" discharged by the machine is about 3 times the "pure water" produced. The concentrated water is purified water which is filtered by a filter liner of a pre-arranged micro-filtration membrane, and is directly discharged to cause waste. The above-mentioned drawbacks and disadvantages make it difficult to widely popularize the water purifier.

When the vertical filter liner cavity is arranged at the upper part of the inner side of the U-shaped shell and is integrated with the U-shaped shell, the position of the swing shaft is correspondingly fixed, so that the position of the swing lock hook device and the corresponding position of the lock hook structure of the upper cover are correspondingly determined. Usually, a hollow shaft sleeve structure is arranged at one end of a swing hook plate of the single-shaft swing lock hook structure or one end of a connecting rod structure of the double-shaft swing lock hook structure, and the hollow shaft sleeve structure is coaxial with the swing shaft support, and then the swing shaft is axially inserted into the swing hook plate of the single-shaft swing lock hook structure or the connecting rod structure of the double-shaft swing lock hook structure to swing around the swing shaft on the swing shaft support. At the moment, the swing shaft has the functions of the shaft and the pin, and then the swing latch hook device and the swing shaft are connected and matched into a whole.
In the embodiments 1 and 2 and the corresponding modified embodiments, the upper cover is set to be a flip structure, for example, a flip mode of one of a front flip, a rear flip and a side flip is adopted. One side of the flip structure is hinged with the U-shaped shell, and the other opposite side is connected with the U-shaped shell in an up-and-down matching way through a swing latch hook device to form a closed filter liner cavity; the pendulum shaft of the swing latch hook device is arranged on the side vertical surface of the vertical filter liner cavity.
Example 3. On the basis of embodiments 1 and 2 and corresponding modified embodiments, the upper cover is set to be a cover moving structure, and as a first mode of the embodiment, the swing shaft of the swing latch hook device is arranged at the front side and the rear side of the vertical filter element cavity. In the second mode of the present embodiment, the swing shaft of the swing latch hook device is disposed at the left and right positions of the vertical filter chamber. In a third mode of the present embodiment, the swing shafts of the swing latch hook device are disposed at four corner positions of the vertical filter element cavity. When the swing shafts are arranged at the four corner positions of the vertical filter element cavity, the swing hook plate of the swing latch hook device can be set into an arc-shaped structure according to the design requirement of appearance modeling, and the arc radius of the swing hook plate corresponds to the arc radius of the four corner structures of the U-shaped shell.
As an improvement, the left side and the right side of the U-shaped shell are provided with undercut structures, the upper parts of the undercut structures are arranged into structures with the lower end surfaces not closed to form a lifting handle structure which is lifted upwards, and the inner cavity space of the corresponding U-shaped shell is in an I shape. At the moment, on the basis of a vertical filter container cavity corresponding to an original U-shaped shell with a rectangular port, the original width size of the vertical filter container cavity is kept, the length size of the vertical filter container cavity is shortened, and an outward-extending swing shaft support is arranged at a relevant position corresponding to the original length and used for supporting swing shafts originally arranged at four corner positions, and the structure of the swing shaft support is shown in the attached drawing.
Example 4. Example 4 is the most preferred example. On the basis of the embodiment 3 and the corresponding improved embodiment, the swing latch hook device adopts a double-shaft swing latch hook structure; the connecting rod structure is provided with a clamping structure, and the vertical filter liner cavity is provided with a matching clamping structure; the matched clamping structure is positioned beside the rotating channel of the clamping structure, is limited through interference fit with the clamping structure and corresponds to the closed state of the swing lock hook device; the hook plate lock hook drives the clamping structure on the connecting rod to rotate around the swing shaft, and the clamping structure is in interference fit with the matched clamping structure through the clamping structure and corresponds to the opening state of the swing lock hook device.

For example, when the three positions are not in a straight line position, even if the connecting rod is subjected to a certain external force to rotate around the swing shaft, as long as the acting force applied to the clamping structure on the connecting rod is not enough to overcome the friction force generated by the interference tightness fit between the clamping structure and the matched clamping structure, the connecting rod cannot easily move, and therefore the swing hook plate is driven to be disengaged from the connection fit with the lock hook structure of the upper cover. When the acting force applied to the clamping structure is enough to overcome the friction force generated by the interference tightness fit between the clamping structure and the matched clamping structure, the swinging hook plate is driven to correspondingly move to enable the hook plate and hook structure at the matched end of the swinging hook plate to be in interference tightness fit with the matched clamping structure, and the swinging hook plate and hook structure are separated from the hook structure of the upper cover to form the opening state of the swinging hook device so as to open the upper cover.

The matching clamping structure 4 is also fixed on the vertical filter liner cavity 1 and corresponds to the swing shaft 2, namely, the clamping structure (not shown) on the connecting rod coaxially hinged with the swing shaft 2. The four swing shafts are respectively arranged at four notches (not shown) at four corners of the U-shaped shell correspondingly. An undercut structure is arranged in the space between the two swing shaft supports 3 on the side wall of the vertical filter tank cavity 1 corresponding to the U-shaped shell, the upper part of the undercut structure is arranged to be a structure with the lower end face not closed to form an upward handle lifting structure, and the space of the inner cavity of the corresponding U-shaped shell is in an I shape. The adoption of the connected structure of the fixed swing shaft 2, the matched clamping structure 4 and the vertical filter element cavity 1 facilitates the connected injection molding of the three.
As a special case of the biaxial swing latch hook structure mode, a triaxial swing latch hook structure mode is derived. On the basis of a double-shaft swing hook structure mode, three connection matching positions of a hook plate hook structure, a swing shaft and a connecting rod structure are arranged at specific positions (such as the three connection positions are arranged at a straight line position), in order to control the separation track of the movement of the hook plate hook structure of the swing hook plate and the hook structure of the upper cover, the movement track of the swing hook plate needs to be controlled, and if the hook plate hook structure is prevented from touching other structures (such as a turnover cover) arranged on the upper cover in the movement process, the swing hook plate has special rotation requirements. At this time, the swing latch hook device can also adopt a hook plate latch hook structure at the matching end of the swing hook plate and a swing shaft end of a first connecting rod structure which is additionally arranged to be respectively in contact fit connection with the latch hook structure of the upper cover and the swing shaft of the vertical filter chamber body, the hinged end of the swing hook plate is hinged with one end of a second connecting rod structure, and the second connecting rod structure and the hinged structure at the other hinged end of the first connecting rod structure are hinged with each other to form a three-shaft swing latch hook structure with two middle non-fixed swing shafts. In the present case, the derived three-axis swing latch hook structure mode is also regarded as a special two-axis swing latch hook structure mode.

For example, the swing latch hook devices disposed at four corners (arc-shaped) of the U-shaped housing are rectangular. The corresponding swing hook plate corresponds to the notch shape and is of an arc-shaped structure.
As a further improvement of the embodiments 1, 2, 3, 4 and the corresponding modified embodiments, an operation space is provided below the notch. The swing hook plate is usually lifted upwards through the operating space to be separated from the hook structure of the upper cover, so that the opening state of the swing hook device is formed, and then the upper cover is opened. If all the gaps are in a combined shape of an upper rectangle and a lower semicircle, the semicircle part is an operation space.
Furthermore, the operating space can also be arranged directly on the structure of the swing hook plate. Generally, a concave structure corresponding to an operation space is provided at a lower portion of an outer surface of the swing hook plate.
In embodiments 1, 2, 3, and 4 and the corresponding modified embodiments, the hook plate latch hook structure at the upper mating end of the swing hook plate is an inner concave structure; the upper cover is provided with a lock hook structure or an upper convex lock hook structure provided with slots at two sides, wherein the lock hook structure is the upper convex lock hook structure, an inner side upper concave structure of the matching end of the swinging hook plate in a closed state of the swinging lock hook device is in upper and lower mutual insertion fit with the upper convex lock hook structure on the upper cover, and the upper cover and the U-shaped shell are connected into a whole; the upper convex latch hook structure with the slots on two sides is arranged on the latch hook structure, two side plates additionally arranged on the swing hook plate in the closed state of the swing latch hook device are inserted into the slots on two sides of the upper convex latch hook structure of the upper cover, the inner side upper concave structure of the matching end of the swing hook plate is in upper and lower mutual insertion fit with the upper convex latch hook structure of the upper cover, and the upper cover and the U-shaped shell are connected into a whole.
