Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment, and in particular relates to an under-sink water purification device. Background Art

[0002] Since tap water contains metal ions such as calcium, magnesium, and iron, the water has a certain hardness. In order to reduce the hardness of the water and remove metal ions such as calcium and magnesium in the water, it is usually necessary to soften the water with a water softener. The water softener usually includes a resin tank filled with resin and a salt box. It uses the functional ions of the resin to exchange with the calcium and magnesium ions in the water, thereby adsorbing the calcium and magnesium ions in the water. When the resin adsorption reaches saturation, its adsorption capacity decreases, and the resin needs to be regenerated at this time. The resin regeneration process is to rinse the resin tank with brine in the salt box to replace the calcium and magnesium ions in the resin, so that the resin can restore its ability to soften water. The water softener needs to add concentrated brine during use, and the conventional way is to add water and solid salt to the salt box.

[0003] With the continuous improvement of living standards, the use of water purification equipment with water softening devices has gradually become popular in households, such as water softeners, whole-house water purifiers, etc. When installing, users generally prefer to install them under the kitchen or embedded in the cabinet, which is both beautiful and can make full use of the kitchen space. In conventional water purification equipment, most of the salt adding methods are to set a flap on the top of the water softening equipment, and open the cover to add salt by flipping the flap to a certain angle. For some kitchens with smaller space, the water purification equipment is embedded in the cabinet, and the gap between the top of the water purification equipment and the top of the cabinet is very small, resulting in insufficient flap angle when adding salt, inconvenient salt adding operation, and even needing to pull the water purification equipment out of the cabinet to add salt, which greatly reduces the user experience.

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The components of the embodiment of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. 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.

[0025] See also Figure 1-5The embodiment of the utility model provides an under-sink water purification device, which includes a housing 1, a door body 11 is rotatably connected to the housing 1, a water softening device is installed in the installation cavity of the housing 1, and the water softening device includes a brine tank 2 and a resin tank 3. The brine tank 2 is connected to the resin tank 3 through a water pipe, so that the brine tank 2 conveys brine to the resin tank 3. The brine tank 2 has a cavity for accommodating brine, which is provided with a salt adding port 21, and a salt adding device 4 is installed above the salt adding port 21. Salt is added to the salt adding port 21 through the salt adding device 4, and finally the salt is dissolved in the water in the cavity of the brine tank 2 to form brine. The salt adding device 4 is located on a side close to the door body 11, and the door body 11 covers the outside of the salt adding device 4. When the user needs to add salt, the door body 11 is opened, the salt adding device 4 is exposed, and salt is added to the salt adding device 4, and finally the salt enters the brine tank 2.

[0026] The under-sink water purification device of this embodiment adopts an open-door structure. When the user adds salt, he only needs to open the door to add salt through the salt adding device 4 above the salt adding port 21, which is easy to operate.

[0027] Please refer to Figure 1-3 Specifically, the housing 1 is provided with an opening 12, and the salt adding device extends into the installation cavity through the opening 12. When the user opens the door 11, the opening 12 can be seen. When the user adds salt, the user extends the salt adding device 4 into the opening 12. The under-sink water purification device of this embodiment adopts the opening 12 provided on the housing 1, so that the salt adding device 4 can be completely embedded in the installation cavity, and the water purification device is more beautiful as a whole and can be smaller in size.

[0028] More specifically, the salt adding device 4 includes a salt adding tray 41, and the salt adding tray 41 is provided with a feeding port 411, and the position of the feeding port 411 corresponds to the position of the salt adding port 21, and salt is added to the brine tank 2 through the feeding port 411. In this embodiment, the feeding port 411 is located directly above the salt adding port 21, and after the user adds salt to the salt adding tray 41, the solid salt falls from the feeding port 411 and falls into the cavity of the brine tank 2 through the salt adding port 21.

[0029] See also Figure 2-5 In order to prevent salt from spilling out during the salt adding process, a feed pipe 412 connected to the feeding port 411 is provided at the lower part of the salt adding tray 41. The feed pipe 412 is inserted into the salt adding port 21, and the salt added from the feeding port 411 falls into the brine tank 2 through the feed pipe 412. The feed pipe 412 can prevent the salt from being scattered to the outside of the brine tank 2 when too much salt is added during the process of falling from the feeding port 411.

[0030] Furthermore, a groove surface 413 is provided on the upper part of the salt adding tray 41, and the groove surface 413 is inwardly contracted toward the feeding port 411 and connected to the feeding port 411. It is understandable that the groove surface 413 is gradually reduced along the feeding port 411, and its shape can be similar to a bowl, so as to facilitate the operation of adding a large amount of salt at one time. When salt is placed on the groove surface 413, since the groove surface 413 is inwardly contracted toward the feeding port 411, the salt will slide along the groove surface 413 toward the feeding port 411, and finally fall into the brine tank 2 through the discharge pipe 412.

[0031] Please refer to Figure 2-3 In the present embodiment, in order to stably install the salt adding tray 41 above the salt adding port 21, a first bracket 13 is provided in the installation cavity of the shell 1, and the first bracket 13 is wrapped around the upper part of the brine tank 2. The first bracket 13 has a mounting port 131, and the feed pipe 412 passes through the mounting port 131 and is inserted into the salt adding port 21, so that the salt adding tray 41 is stuck on the first bracket 13.

[0032] Furthermore, a second bracket 14 is also provided in the installation cavity, and the second bracket 14 is provided with a salt adding space 141, the salt adding space 141 is connected to the opening 12, and the salt adding space 141 is located above the salt adding tray 41. The second bracket 14 of this embodiment is composed of a plurality of side panels, and the plurality of side panels enclose a chamber with openings on both side panels, and the chamber is the salt adding space 141; the second bracket 14 is installed at a position directly opposite to the opening 12, and is located above the salt adding tray 41, and the side of the second bracket 14 close to the opening 12 has no side panel; the side of the second bracket 14 close to the salt adding tray 41 also has no side panel, so that the salt adding space 14 is connected to the feeding port 411.

[0033] For further information, see Figure 4-5 The upper portion of the salt adding tray 41 is provided with a support edge 414, and the support edge 414 is fixedly mounted on the inner wall of the second bracket 14, so that the salt adding tray 41 is more stably fixed above the salt adding port 21, and the salt adding tray 41 is prevented from shifting during the salt adding process. In this embodiment, the support plate 414 is fixed to the second bracket 14 by screws.

[0034] See also Figure 1-3The salt adding device 4 further includes a cover 42, which is detachably covered on the salt adding tray 41, so that the cover 42 blocks the feeding port 411 to prevent dust or debris from falling into the brine tank 2. Specifically, the cover 42 is provided with a gripper 421, which is convenient for the user to remove or cover the cover 42.

[0035] In the under-sink water purification device of this embodiment, when the user needs to add salt, the door 11 is opened, the lid 42 is removed, and salt is placed in the feeding tray 41. The salt slides from the feeding port 411 to the feeding pipe 412, and finally falls into the cavity of the brine tank 2 through the salt adding port 21, and the salt adding is completed. When the salt adding is completed, the lid 42 is covered on the salt adding tray 41, and the door 11 is closed.

[0036] The technical features of the above-described embodiments may be combined arbitrarily. All possible combinations of the technical features in the above-described embodiments are not described. As long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
