Description

Technical Field

[0001] The invention relates to the technical field of water purifiers, and in particular to a membrane capacitor deionization water purifier. Background Art

[0002] Capacitive deionization (MCDI) is an electrochemical technology that can simply and effectively remove total dissolved solids (TDS) in water. Under the action of the electric field, the double layer formed between the electrode and the solution is used, and polar molecules or ions are stored in the double layer and removed. When the electrode is saturated, a reverse electric field can be applied to make the ions leave the electrode for regeneration.

[0003] The above technology can also be well applied in the field of water purifiers. There are many types of MCDI water purifiers on the market. However, the inventor found that in the actual use of this type of water purifier, the water source is often treated by adsorption and then processed by the MCDI processing unit, and then discharged and stored in the water tank. The water source treated by the MCDI processing unit is not sterilized and disinfected. Although there are some disinfection and sterilization measures in this field, they are aimed at water sources that have been stored and left to stand or have weak fluidity, so the sterilization effect of the sterilization equipment on the above water source is limited; at the same time, the inventor found that when the MCDI type water purifier is installed with the household tap water outlet pipe, due to the relatively large water pressure of the outlet water, it is easy to leak here, and additional protective treatment is required. In response to the above problems, the inventor proposes a membrane capacitor deionization water purifier that can effectively prevent water leakage at the connection between the MCDI water purifier inlet pipe and the external water outlet pipe, and at the same time, it can effectively disinfect and sterilize the water source after MCDI purification.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1The present invention provides a technical solution: a membrane capacitor deionization water purifier, comprising a base frame 1 for installing the entire water purifier, a connecting pipe 2 connected to an external water outlet pipe 10 with internal threads, a leakage-proof protective sleeve 3 arranged at the connection between the connecting pipe and the water outlet pipe 10 with internal threads, a distribution box 4 arranged in the middle of the base frame 1, and a pretreatment adsorption tank 5, an MCDI treatment tank 6, a sterilization tank 7 and a water outlet pipe 9 respectively connected to the distribution box 4, the leakage-proof protective sleeve 3 is used to play a role of secondary sealing protection, the connecting pipe 2 is connected to the distribution box 4, the distribution box 4 is used to distribute the water source entering the distribution box 4 through the connecting pipe 2, and at the same time distribute the water source treated by the pretreatment adsorption tank 5, the MCDI treatment tank 6, and the sterilization tank 7, and the sterilization tank 7 is provided with a device for improving the fluidity of the water source entering the sterilization tank 7 and the contact area between the water source and the sterilization lamp. The present invention, by providing an anti-leakage protective sleeve 3, can effectively play a role of secondary sealing protection when there is a leak at the connection between the connecting pipe 2 and the external water outlet pipe 9; by providing a sterilization tank 7, the water source treated by MCDI can be sterilized, and at the same time, by providing a device in the sterilization tank 7 to improve the fluidity of the water source entering the sterilization tank 7 and the contact area between the water source and the sterilization lamp, the sterilization efficiency and sterilization effect of the sterilization tank 7 on the water source can be effectively improved. In existing water purifiers, integrated distribution boxes 4 for distributing water flow are also relatively common. The use of multiple groups of water pipes integrated in the box and a driving water pump can transport the water source in the multi-stage treatment tank on demand. For those skilled in the art, this integrated distribution box 4 also belongs to the prior art, so the technical solution of the present invention will not be repeated.

[0029] In this embodiment, the anti-leakage protection sleeve 3 includes a sleeve body 31 sleeved at the connection between the connecting pipe 2 and the outlet pipe 10 with internal threads, a first tapered portion 32 and a first threaded portion 33 arranged at the lower part of the sleeve body 31, a second tapered portion 34 and a second threaded portion 35 arranged at the upper part of the sleeve body 31, and a first matching sleeve 36 and a second matching sleeve 37 threadedly connected to the first threaded portion 33 and the second threaded portion 35 respectively. Sealing gaskets 310 are arranged at the gap between the first tapered portion 32 and the outer surface of the connecting pipe 2, and between the second tapered portion 34 and the outer surface of the outlet pipe 10 with internal threads. The first tapered portion 32 and the second tapered portion 34 can deform inwards and squeeze the sealing gaskets 310 when subjected to external pressure. Figure 3 , 4As shown in Figure 5, by setting the sealing gasket 310 on the first tapered portion 32 and the second tapered portion 34, after the connecting pipe 2 and the water outlet pipe 10 with an internal thread are installed, the personnel can twist the first matching sleeve 36 and the second matching sleeve 37 respectively so that the first tapered portion 32 and the second tapered portion 34 are respectively pressurized, so that the two tapered portions continuously squeeze the sealing gasket 310, thereby effectively improving the sealing performance of the connection between the sleeve body 31 and the connecting pipe 2 and the water outlet pipe 10 with an internal thread, so that the entire sleeve body 31 cooperates with the sealing gasket 310, and can play a secondary sealing protection role when there is a leakage at the connection between the connecting pipe 2 and the water outlet pipe 10 with an internal thread, thereby effectively ensuring the practicality of the entire water purifier.

[0030] Specifically, the anti-leakage protection sleeve 3 also includes a protruding block 38 fixedly connected to the outer surface of the first matching sleeve 36 and the second matching sleeve 37, and a telescopic shaft 39 arranged between the upper and lower protruding blocks 38. The telescopic shaft 39 includes a sleeve 391 fixedly connected to the upper surface of the protruding block 38, an elastic member 392 fixedly connected to the bottom of the inner cavity of the sleeve 391, and a sliding shaft 393 slidably connected to the inner cavity of the sleeve 391. One end of the elastic member 392 is fixedly connected to the lower end of the sliding shaft 393. The first threaded portion 33 and the second threaded portion 35 have opposite threaded directions. Figure 4 and 5 As shown, a telescopic shaft 39 is arranged between the first mating sleeve 36 and the second mating sleeve 37. At the same time, since the thread rotation directions of the first threaded portion 33 and the second threaded portion 35 are opposite, and the sliding shaft 393 can only slide up and down in the sleeve 391, the telescopic shaft 39 cooperates with the first threaded portion 33 and the second threaded portion 35 with opposite thread rotation directions to form a synchronization device that synchronously drives the first mating sleeve 36 and the second mating sleeve 37 to move up or down. Therefore, when personnel need to adjust the mating sleeve, they only need to rotate the sleeve body 31, so that the mating sleeves make linear movements along the center line of the shaft body to move closer to or away from each other, and then the personnel can quickly adjust the squeezing or relaxation of the tapered portion by the mating sleeve, so that the sleeve body 31 can be quickly disassembled and assembled.

[0031] In this embodiment, an ultraviolet lamp 43 is arranged in the sterilization tank 7, a water inlet funnel 71 is fixedly connected to the upper part of the inner cavity of the sterilization tank 7, a concentrated water outlet hole 72 is opened in the inner cavity of the water inlet funnel 71, and a spiral channel 73 is arranged on the inner cavity wall of the sterilization tank 7, the spiral channel 73 spirally surrounds the ultraviolet lamp 43, and the uppermost end of the spiral channel 73 is located directly below the concentrated water outlet hole 72. Figure 6 and 7As shown, by setting the water inlet funnel 71, the water entering the sterilization tank 7 flows into the water inlet funnel 71 uniformly. At this time, the water flows from the centralized water outlet 72 uniformly into the spiral channel 73, and then the water flows along the spiral channel 73 into the bottom of the sterilization tank 7. At this time, the ultraviolet sterilization lamp can directly irradiate the flowing water, greatly improving the sterilization effect on the water source.

[0032] Specifically, the lower end surface of the distribution box 4 is detachably mounted with the pretreatment adsorption tank 5, the MCDI treatment tank 6 and the sterilization tank 7 through the mounting sleeve 42, the ultraviolet lamp 43 and the MCDI treatment tank 6 are electrically connected to the distribution box 4, the distribution box 4 is electrically connected to the external power supply through the plug 41, and a sealing ring is provided at the gap between the lower part of the water inlet funnel 71 and the ultraviolet lamp 43. Figure 7 As shown, by providing a sealing ring at the gap between the lower part of the water inlet funnel 71 and the ultraviolet lamp 43, the sealing performance of the water inlet funnel 71 and the ultraviolet lamp 43 after installation can be effectively guaranteed, and the water flow in the water inlet funnel 71 can be effectively prevented from directly leaking into the bottom of the sterilizing tank 7 from the installation gap here, further ensuring the sterilization effect of the sterilizing lamp. In the prior art, the MCDI processing unit does not need to be replaced frequently under normal conditions. Only when a fault occurs, a professional needs to come to the door for maintenance. In the prior art, this detachable electrical connection method is relatively common, and the technical solution of the present invention will not be repeated.

[0033] Furthermore, the outer surfaces of the installation sleeve 42 and the pretreatment adsorption tank 5, the MCDI treatment tank 6 and the sterilization tank 7 are all provided with a distinguishing mark 8, and the distinguishing mark 8 is used to distinguish the three types of tanks with different functions and the installation sleeves 42 installed in conjunction with the three types of tanks. Figure 1 , 2 As shown in FIGS. 6 and 7 , by setting the distinguishing mark 8 , personnel can quickly identify the three different types of tanks, thereby facilitating personnel to quickly assemble the three tanks on the correct installation sleeve 42 on the distribution box 4 , thereby reducing the installation error rate and saving the time required for installation.

[0034] In this embodiment, the side of the base frame 1 close to the distribution box 4 is evenly spaced and arranged with limit blocks 11, which are used to elastically engage the wires of the plug 41. Figure 1 and Figure 2 As shown, by providing the limit block 11, the wires of the plug 41 can be elastically engaged and gathered when the entire water purifier is installed, thereby preventing the connecting wires of the plug 41 from spreading out and affecting daily cleaning and maintenance of the water purifier.

[0035] In this embodiment, the lower end of the connecting pipe 2 is connected to the distribution box 4 through the electromagnetic valve 21, and the upper end of the connecting pipe 2 is provided with a threaded connector 22. Figure 2As shown, by providing the threaded connector 22, the connecting pipe 2 can be conveniently and quickly installed with the water outlet with internal threads, thereby greatly improving the application range of the entire water purifier.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "includes an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
