Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, in particular to a novel backwashing filtering water purifier. Background Art

[0002] The water purifier is used to make purified water for drinking water and other domestic water, which is very beneficial to people's health. Although the current water purifier used to purify tap water has a sewage outlet, the water only flows from one end of the filter element of the water purifier to the other end of the filter element during sewage discharge, and the water does not flow from the outside to the inside through the fine holes on the filter element that play a filtering role. Therefore, the impurities such as silt accumulated in the filter element can only be discharged through the sewage outlet to a low degree, and the sewage discharge time is long, the water is wasted a lot, and the sewage discharge effect is poor. After the water purifier is used for a long period of time, the silt and other impurities in the tap water will accumulate more and more on the inner surface of the fine holes on the filter element that play a filtering role, and the more blocked and tighter the water purifier is, the smaller the purified water output of the water purifier will be, thereby affecting the efficacy of the water purifier and the service life of the filter element. In order to realize that the water flows from the outside to the inside through the fine holes on the filter element that play a filtering role, the silt and other impurities blocked on the inner surface of the small hole can be quickly loosened and fallen off by the backwashing of the water flow;

[0003] The existing patent CN204601799U filtering water purifier has a filter element inside the hollow shell of the water purifier, and the shell is provided with a water inlet, a backwashing port, a water purification port, and a sewage outlet. The main water inlet on one end of the water purifier shell is divided into two water inlets, and a switch capable of controlling the direction of water flow is built in at the fork of the two water inlets, one of the water inlets is connected to the backwashing port through a pipe, and the backwashing port and the water purification port on the water purifier shell are both connected to the same gap between the shell and the filter element in the middle of the water purifier, and the other water inlet and sewage outlet on the water purifier shell are respectively connected to different gaps between the shell and the filter element at both ends of the water purifier;

[0004] However, in this patent, although a backwash mechanism is provided to clean the filter element, impurities on the filter element cannot be effectively removed by the backwash mechanism alone. Therefore, the outer shell needs to be opened to disassemble the filter element for fine cleaning. Due to the integrated structural design of the outer shell, it is very inconvenient to disassemble the filter element. Therefore, the utility model proposes a new backwash filter water purifier.

The advantage of this structure is that when the impurities on the filter component cannot be cleaned due to the backflushing effect, the first shell and the second shell can be disassembled, the filter component can be removed, and the cleaning can be carried out directly. In addition, the filter component and the first shell and the second shell are a snap-fit ​​structure. The advantage of this structure is that after the first shell and the second shell are separated, the filter component can be directly removed to improve work efficiency. Furthermore, the filter component is a split structure. The advantage of this structure is that when the filter cartridge needs to be replaced, the filter cartridge can be removed from between the two snap-fit ​​plates and directly replaced with a new filter cartridge.

[0020] 2. In the utility model, the water purification component is limited by a limiting fixing component, so that the first shell and the second shell are tightly fitted during use to prevent the first shell and the second shell from being separated during use. The connection between the first shell and the second shell is further sealed by a sealing plate to prevent the internal liquid of the water purification component from flowing out from the connection between the first shell and the second shell. When in use, the sealing plate can also prevent the high-pressure water flow inside the water purification component from directly impacting the sealing ring, causing the sealing ring to impact and displace and lose the sealing effect, thereby interfering and improving the sealing performance of the device during use.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1-6As shown, the utility model provides a technical solution: a novel backwash filtering water purifier, comprising a water purifier body 1, the water purifier body 1 comprising a limit fixing assembly 2 and a water purification assembly 3, the limit fixing assembly 2 being clamped on the upper and lower sides of the water purification assembly 3; the water purification assembly 3 comprising a first shell 31 and a second shell 32, a backwash outlet pipe 34 being arranged at the bottom of the first shell 31 and the second shell 32, a backwash inlet pipe 33 being arranged at the top of the first shell 31 and the second shell 32, a limit frame 37 being arranged on the inner wall of the first shell 31 and the second shell 32, two limit frames 37 being arranged in total, and the two limit frames 37 being symmetrical with each other at the center of the first shell 31, a filter assembly 5 being clamped on the two limit frames 37, the first shell 31 being located above the filter assembly 5 and being fixedly connected with a water inlet pipe 35, A water outlet pipe 36 is fixedly connected to one side of the filter component 5 on the second shell 32. The water purification component 3 is a detachable structure. The advantage of this structure is that when the impurities on the filter component 5 cannot be cleaned due to the backwash effect, the first shell 31 and the second shell 32 can be disassembled, and the filter component 5 can be removed and cleaned directly. In addition, the filter component 5 and the first shell 31 and the second shell 32 are a snap-on structure. The advantage of this structure is that after the first shell 31 and the second shell 32 are separated, the filter component 5 can be directly removed, and the water to be filtered can be introduced into the interior of the water purification component 3 through the water inlet pipe 35. Under the action of the filter component 5, the sewage is filtered, and the filtered water is discharged through the water outlet pipe 36, which solves the technical problem that the water purification component 3 cannot be separated, resulting in difficulty in cleaning the filter component 5.

[0031] Furthermore, Figure 4 and Figure 6 As shown: the filter assembly 5 includes a filter cartridge 51, a filter hole 53 is opened on the filter cartridge 51, and the upper and lower ends of the filter cartridge 51 are fixedly connected with a snap-in disk 52, the snap-in disk 52 and the limit frame 37 are snap-fitted to each other, and the filter assembly 5 and the first shell 31 and the second shell 32 are installed in a snap-fit ​​manner. The advantage of this installation is that after the first shell 31 and the second shell 32 are disassembled, the filter assembly 5 can be directly removed for fine suction, thereby improving work efficiency. Furthermore, the filter assembly 5 is a detachable structure. When the filter cartridge 51 is damaged and needs to be replaced, the filter cartridge 51 can be replaced with a new one by separating the filter cartridge 51 from the snap-in disk 52, thereby solving the technical problem of slow work efficiency in replacing the filter assembly 5.

[0032] In the above solution, there is still a problem that the first housing 31 and the second housing 32 may separate under the action of water pressure during use. Figure 3As shown: the limit fixing assembly 2 includes a lower limit seat 21 and an upper limit seat 22, and the lower limit seat 21 and the upper limit seat 22 are both provided with a flange connection plate 23 at one end close to each other, and a support leg 25 is provided at the bottom of the lower limit seat 21, and the support leg 25 is distributed in a ring shape, and a movable opening 24 is opened on the upper limit seat 22, and the width of the movable opening 24 is greater than the width of the water inlet pipe 35. The first shell 31 and the second shell 32 are limited by the limit fixing assembly 2. Since the upper limit seat 22 and the lower limit seat The design of the arc structure 21 allows the first shell 31 and the second shell 32 to fit tightly together after the limiting fixing component 2 is snapped onto the first shell 31 and the second shell 32, thereby preventing the first shell 31 and the second shell 32 from separating during use and causing water leakage in the water purification component 3. The water purifier body 1 is erected at a specified position through the support legs 25, so that a certain space is reserved between the movable port 24 and the contact surface, and installation space is reserved for the installation of the sewage inlet pipe. The movable port 24 reserves snap-on space for the water inlet pipe 35.

[0033] The above solution also has the problem of water seepage at the connection between the first housing 31 and the second housing 32 under the action of water pressure, such as Figure 4 and Figure 5 As shown: a sealing ring 4 is embedded between the first shell 31 and the second shell 32, and a sealing plate 41 is provided at the connection between the second shell 32 and the first shell 31. The sealing ring 4 improves the sealing effect between the first shell 31 and the second shell 32 to prevent water inside the water purification component 3 from flowing out through the connection between the first shell 31 and the second shell 32, and the sealing plate 41 further improves the sealing effect at the connection between the first shell 31 and the second shell 32.

[0034] Working principle:

[0035] like Figure 1-6 As shown, first, the water purifier body 1 is installed in the specified position through the support legs 25, and then the water inlet pipe 35 is fixedly connected to the water inlet connecting pipe, and the water outlet pipe 36 is fixedly connected to the water outlet connecting pipe. Further, the backwash outlet pipe 34 is fixedly connected to the water pump output end through the connecting pipe, and the backwash inlet pipe 33 is connected to the drainage connecting pipe. After preparation, turn on the sewage tank output pump, and introduce the sewage into the interior of the water purification component 3 through the water inlet pipe 35. At this time, the sewage is filtered under the action of the filter component 5, and the filtered water is discharged through the water outlet pipe 36. When the water purifier body 1 needs to be backwashed and cleaned, close the water inlet pipe 35 and turn on the water pump. At this time, under the action of the water pump, the backwash outlet pipe 34 will be pumped into the interior of the filter component 5, and the interior of the filter component 5 will be flushed under the action of high-pressure water, and the wastewater generated by flushing will be discharged through the backwash inlet pipe 33.
