Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to a water purifier. Background Art

[0002] There are usually two ways to source raw water for a water purifier. The first way is to connect the water purifier directly to the municipal tap water supply pipe. The second way is to set up a water tank for storing raw water (i.e., raw water tank) outside or inside the water purifier, and provide raw water to the water purifier through the raw water tank.

[0003] Regarding the second method, as the raw water tank ages, the water quality at the bottom of the tank deteriorates. To prevent the poor quality of the raw water tank from affecting the life of the purification filter, a water level sensor is installed in the raw water tank. When the water level reaches a preset value, the sensor will remind the user to refill the tank. However, since the RO reverse osmosis membrane filter produces concentrated water during the purification process, this concentrated water will flow back into the raw water tank. This backflow of concentrated water will cause the water level in the raw water tank to rise, causing the water purifier to switch between warning of water shortage and canceling the reminder, which can easily lead users to mistakenly believe that the water purifier is malfunctioning.

[0116] To make the technical solutions and beneficial effects of the present invention more clearly understood, the following describes the present invention in detail by listing specific embodiments. Unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application belongs.

[0118] In this utility model, the terms "first" and "second" are used solely for descriptive clarity and should not be construed as indicating the relative importance of the features indicated or the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, and "several" means at least one, unless expressly specified otherwise.

[0119] In this utility model, unless otherwise expressly defined, the terms "install," "connect," "connect," "fix," "dispose," etc. should be understood broadly. For example, "connection" can mean fixed connection, detachable connection, or integral molding; it can be mechanical or electrical; it can be direct connection or indirect connection through an intermediary; it can also refer to internal communication between two components or the interaction between two components.

[0120] In the present invention, unless otherwise clearly defined, when a first feature is “on,” “above,” “above,” “above,” “below,” “below,” or “below” a second feature, the first feature and the second feature may be in direct contact, or the first feature and the second feature may be in indirect contact via an intermediate medium. Moreover, when a first feature is “on,” “above,” or “above” a second feature, it may mean that the first feature is directly above or obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than the horizontal height of the second feature. When a first feature is “below,” “below,” or “below” a second feature, it may mean that the first feature is directly below or obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than the horizontal height of the second feature.

[0121] The “front”, “back”, “left”, “right”, “up” and “down” mentioned in this utility model are all Figure 1 and Figure 17 The markings in the table shall prevail.

[0122] The following is based on Figures 1 to 17 The utility model of the water purifier is described in detail.

[0123] In this embodiment, if Figure 1 and Figure 2As shown, the water purifier 100 includes a raw water tank 11, a purification mechanism (not shown), a water level detection mechanism 2, and a control module. The raw water tank 11 includes a chamber 111 for storing raw water. The water inlet of the purification mechanism is connected to the raw water tank 11. The purification mechanism includes a pre-filter, a reverse osmosis membrane filter, and a post-filter. The concentrate water supply port of the reverse osmosis membrane filter is connected to the raw water tank 11. When the water purifier 100 starts to produce water, the raw water in the chamber 111 flows out and passes through the pre-filter, reverse osmosis membrane filter, and post-filter in sequence. After being purified by the purification mechanism, the concentrate produced by the reverse osmosis membrane filter during the purification process flows back to the raw water tank 11. Of course, in other feasible embodiments, according to actual needs, the purification mechanism may also include a pre-filter element and a reverse osmosis membrane filter element, or a reverse osmosis membrane filter element and a post-filter element, or a composite filter element including a reverse osmosis membrane filter material and a pre-filter material, or a composite filter element including a reverse osmosis membrane filter material and a post-filter material, or a composite filter element including a pre-filter material, a reverse osmosis membrane filter material and a post-filter material, etc. The reverse osmosis membrane filter element described above in this document refers to a filter element that at least includes a reverse osmosis membrane filter material, which can be a single filter material filter element that only includes a reverse osmosis membrane filter material, or a composite filter element that includes a reverse osmosis membrane filter material and other filter materials. This application does not make specific limitations on this.

[0124] like Figure 1 and Figure 2 As shown, the water level detection mechanism 2 includes a first water level detection element 21 and a second water level detection element 22 spaced apart from each other from top to bottom. The first water level detection element 21 is used to obtain first water level information within the chamber 111, and the second water level detection element 22 is used to obtain second water level information within the chamber 111. The control module is used to receive the second water level information obtained by the second water level detection element 22 and, during the water production process, control the water purifier 100 to issue a water shortage reminder if the second water level information indicates that the water level within the chamber 111 has reached the water level line corresponding to the location of the second water level detection element 22 and if the control module determines that the water level within the chamber 111 has reached the lower limit water level, thereby prompting the user to replenish raw water in the raw water tank 11 in a timely manner. In other words, the control module will only control the water purifier 100 to issue a water shortage reminder if the current water level within the chamber 111 meets both the conditions of having reached the water level line corresponding to the location of the second water level detection element 22 and having reached the lower limit water level.

[0125] The chamber 111 forms a first space between the first water level detection element 21 and the second water level detection element 22; the volume V1 of the first space is configured so that, during the process of the water purifier 100 issuing a water shortage reminder, the amount of returned concentrated water cannot fill the first space. Specifically, during the process of the water purifier 100 issuing a water shortage reminder, the concentrated water produced by the reverse osmosis membrane filter element will flow back into the chamber 111, thereby causing the water level in the chamber 111 to rise. This solution limits the size of the first space's volume V1 so that the first space is sufficient to accommodate the returned concentrated water. In this way, the returned concentrated water will not cause the water level to rise above the water level line corresponding to the location of the first water level detection element 21, thereby ensuring that the water purifier 100 will not stop the water shortage reminder and preventing the water purifier 100 from switching between the two states of reminding the raw water tank of water shortage and canceling the reminder.

[0126] By adopting the above technical solution, by configuring the first water level detection element 21 and the second water level detection element 22 spaced apart and distributed in the upper and lower directions, and limiting the height difference between the first water level detection element 21 and the second water level detection element 22, it is ensured that the first space between the first water level detection element 21 and the second water level detection element 22 is sufficient to accommodate the backflow of concentrated water, so that the water purifier 100 maintains a water shortage reminder indication, avoiding the water purifier 100 jumping between the two states of reminding the raw water tank of water shortage and canceling the reminder.

[0127] In the prior art, since the raw water tank is only equipped with one water level detection element, in order to ensure that the water quality meets drinking water requirements, the water level detection element cannot be set too low, otherwise the water quality will be poor and cannot be drunk. The limitation of the water level detection element's setting position leads to a low water production rate. In this solution, the setting height of the first water level detection element 21 can be limited to ensure that the water production rate of the raw water tank 11 reaches above 70%, where the water production rate represents the ratio of the amount of raw water removed from the raw water tank 11 to produce pure water to the initial amount of raw water in the raw water tank 11. Taking the raw water tank 11 with a capacity of 5L as an example, if the first water level detection element 21 is set at the water level corresponding to 1.5L of water in the chamber 111, the water production rate is 70%. If the first water level detection element 21 is set at the water level corresponding to 1L of water in the chamber 111, the water production rate is 80%.

[0128] It should be understood that "water production" herein refers to an operating state in which water in the raw water tank 11 is extracted and purified by a purification mechanism.

[0129] In one embodiment, the water purifier 100 further includes a TDS detection mechanism for obtaining the current TDS value of the water in the cavity 111, that is, for obtaining the current water quality.

[0130] In one embodiment, if Figure 8 As shown, the TDS detection mechanism is a TDS sensor 72. Figure 1 、 Figure 7 and Figure 8 As shown, the water purifier 100 includes a booster pump 31, a waterway plate 32, and a filter cartridge holder 51. The booster pump 31 is located in front of the filter cartridge holder 51 and is used to provide power for the raw water flowing out of the chamber 111 to flow through the purification mechanism. The waterway plate 32 is located below the raw water tank 11. The filter cartridge holder 51 includes a first filter cartridge holder 511 for accommodating a pre-filter cartridge, a second filter cartridge holder 512 for accommodating a reverse osmosis membrane filter cartridge, and a third filter cartridge holder 513 for accommodating a post-filter cartridge. The first filter cartridge holder 511, second filter cartridge holder 512, third filter cartridge holder 513, and raw water tank 11 are arranged in sequence in the left-right direction of the water purifier 100. The bottom of the filter cartridge holder 51 is equipped with a raw water inlet port 514 and a concentrated water outlet port 515. The outlet of the raw water tank 11 is connected to the raw water inlet of the waterway plate 32. The raw water outlet of the waterway plate 32 is connected to the water inlet of the booster pump 31 via a first raw water pipeline 621. The water outlet of the booster pump 31 is connected to the raw water inlet port 514 via a second raw water pipeline 622. The raw water inlet port 514 is connected to the pre-filter cartridge. The concentrated water outlet port 515 is connected to the concentrated water inlet of the waterway plate 32 via a concentrated water output pipeline 63. The concentrated water outlet of the waterway plate 32 is connected to the inlet of the raw water tank 11. The TDS sensor 72 is installed at the bottom of the filter cartridge holder 51 to detect the water quality in the outlet of the second raw water pipeline 622. Of course, the TDS sensor 72 can also be installed on the raw water tank 11. The raw water tank 11 can be removed to collect water when replenishing raw water. In this way, the TDS sensor 72 is preferably set on the filter cartridge holder 51.

[0131] In one embodiment, the control module is further configured to receive the first water level information obtained by the first water level detection element 21, and to control the water purifier 100 to continue making water during the water production process, if the first water level information indicates that the water level in the volume chamber 111 has reached the water level line corresponding to the location of the first water level detection element 21, and if it is determined that the current TDS value is ≥ the first preset TDS value, control the water purifier 100 to continue making water until the first preset water production time is reached, and then control the water purifier 100 to stop making water and issue a water shortage reminder. Specifically, Figure 2As shown, the water level line corresponding to the position of the first water level detection element 21 is the first critical point. When the water level reaches the first water level detection element 21, at this time, if the current TDS ≥ the first preset TDS value, it means that the water quality at this time is poor, and the water purifier 100 cannot continue to make water until the water level drops to the second water level detection element 22. In addition, in order to avoid the situation of jumping between the two states of reminding the raw water tank of water shortage and canceling the reminder, the control module controls the water purifier 100 to continue making water until the first preset water making time is reached, and then stops making water and issues a water shortage reminder indication. During the water making period of the first preset water making time, the backflow of concentrated water will not cause the water level in the cavity 111 to rise to above the water level line corresponding to the position of the first water level detection element 21, so as to ensure that the water purifier 100 maintains the water shortage reminder indication. In this way, it can ensure healthy drinking water while avoiding the user's mistaken belief that the water purifier 100 has a malfunction due to the jumping condition of the water shortage reminder indication.

[0132] In one embodiment, the first preset TDS value is 110, 120, or 150.

[0133] In one embodiment, the control module is further configured to receive the first water level information acquired by the first water level detection element 21 and to, during the water production process, Figure 2 As shown, if the first water level information indicates that the water level in the cavity 111 has touched the water level line corresponding to the position of the first water level detection element 21, and it is determined that the current TDS value is less than the first preset TDS value, the water purifier 100 is controlled to continue making water until the second water level information indicates that the water level in the cavity 111 has touched the water level line corresponding to the position of the second water level detection element 22 and the water level in the cavity 111 reaches the lower limit water level, and the control module controls the water purifier 100 to issue a water shortage reminder indication. Specifically, when the water level reaches the first water level detection element 21, if the current TDS is less than the first preset TDS value, it means that the water quality at this time is good, and the water purifier 100 can continue to produce water until the water level drops to the second water level detection element 22. Moreover, when the water level in the cavity 111 has touched the water level line corresponding to the position of the second water level detection element 22 and the water level in the cavity 111 has reached the lower limit water level, it indicates that the water quality is poor and will consume the life of the purification mechanism too quickly. Therefore, the control module controls the water purifier 100 to issue a water shortage reminder indication.

[0134] Furthermore, the control module is also used in the water production process, such as Figure 2 As shown, if the second water level information indicates that the water level in the cavity 111 has reached the water level line corresponding to the position of the second water level detection element 22, and it is judged that the water level in the cavity 111 has reached the lower limit water level, it means that the water quality is poor and the life of the purification mechanism will be consumed too quickly. That is, the control module controls the water purifier 100 to stop making water while controlling the water purifier 100 to issue a water shortage reminder indication.

[0135] In one embodiment, the water level corresponding to the location of the second water level detection element 22 is configured as the lower limit water level. The water level corresponding to the location of the second water level detection element 22 is the second critical point, and the lower limit water level is the third critical point. The second critical point and the third critical point are located at the same position. Specifically, when the current water level in the chamber 111 reaches the water level corresponding to the location of the second water level detection element 22, the control module controls the water purifier 100 to issue a water shortage reminder and control the water purifier 100 to stop water production.

[0136] In another embodiment, the lower limit water level is lower than the water level line corresponding to the location of the second water level detection element 22, that is, the third critical point is lower than the second critical point. Specifically, when the water level in the container 111 reaches the water level line corresponding to the location of the second water level detection element 22, the water quality in the container 111 is good at this time, and the water level in the container 111 has not reached the lower limit water level. The water purifier 100 does not need to issue a water shortage reminder and can continue to produce water until the water level reaches the lower limit water level.

[0137] Furthermore, when the second water level information indicates that the water level in the chamber 111 has reached the water level line corresponding to the location of the second water level detection element 22, the control module is used to determine that the water level in the chamber 111 has not reached the lower limit water level in response to the current TDS value being less than the second preset TDS value, and the water purifier 100 continues to produce water, wherein the second preset TDS value is less than the first preset TDS. When the water level in the chamber 111 reaches the first water level detection element 21, if the current TDS value is less than the second preset TDS value, it indicates that the water quality at this time is good, and the water purifier 100 can continue to produce water. In this solution, the current TDS value in the raw water tank 11 is determined to determine whether the water level in the chamber 111 has reached the lower limit water level value. In one specific embodiment, the second TDS value is 80, 90, or 100. Of course, in other feasible embodiments, the second preset TDS value = the first preset TDS value.

[0138] Specifically, if the current TDS value is less than the second preset TDS value, the control module may execute any one of the first, second and third solutions.

[0139] Option 1

[0140] In one embodiment, the water purifier 100 further includes a timing module configured to obtain a water production duration. The control module is configured to determine, in response to the water purifier 100 continuing to produce water for a second preset water production duration, whether or not the water level in the chamber 111 has reached a lower limit water level. Specifically, when the water level in the chamber 111 reaches the first water level detection element 21, if the current TDS value is less than the second preset TDS value, indicating that the water quality is good, the control module controls the water purifier 100 to continue producing water until the second preset water production duration is reached. At this point, the water level in the chamber 111 reaches the lower limit water level, at which point the water purifier 100 stops producing water and issues a water shortage warning.

[0141] Option 2

[0142] In one embodiment, the control module is configured to determine, in response to the water purifier 100 continuing to produce water until the water chamber 111 is depleted, that the water level in the chamber 111 has reached a lower limit water level. Specifically, when the water level in the chamber 111 reaches the water level corresponding to the location of the first water level detection element 21, if the current TDS value is less than a second preset TDS value, this indicates that the remaining water in the raw water tank 11 is of good quality, meeting healthy drinking water requirements for continued water production until the water in the raw water tank 11 is depleted, and will not prematurely deplete the lifespan of the purification mechanism. Furthermore, when the booster pump 31 is in an unloaded state, the control module determines that the chamber 111 is depleted of water. The load status of the booster pump 31 is used to determine whether the chamber 111 currently contains water or not.

[0143] Option 3

[0144] In one embodiment, the control module is configured to determine that the water level in the chamber 111 has reached a lower limit water level in response to the water purifier 100 continuing to produce water until the current TDS value exceeds a second preset TDS value or exceeds a first preset TDS value. Specifically, when the water level in the chamber 111 reaches the first water level detection element 21, if the current TDS value is less than the second preset TDS value, it indicates that the water quality is good and water production can continue. Furthermore, during the continued water production process, if it is detected that the water quality has deteriorated to a certain extent, that is, the current TDS value exceeds the second preset TDS value or exceeds the first preset TDS value, it indicates that the current water quality is no longer suitable for drinking. At this time, the water level in the chamber 111 reaches the lower limit water level, and the water purifier 100 is controlled to stop water production and issue a water shortage reminder.

[0145] If the current TDS value is greater than or equal to the second preset TDS value, the control module may execute any one of the fourth, fifth, and sixth solutions.

[0146] Option 4

[0147] In one embodiment, when the second water level information indicates that the water level in the chamber 111 has reached the water level line corresponding to the location of the second water level detection element 22, the control module is configured to determine that the water level in the chamber 111 has reached the lower limit water level in response to a current TDS value ≥ a second preset TDS value. Specifically, when the water level in the chamber 111 reaches the water level line corresponding to the location of the second water level detection element 22, if the current TDS value ≥ the second preset TDS value, this indicates that the quality of the remaining water in the raw water tank 11 is poor and that further water production is unavailable. At this point, the water level has reached the lower limit water level.

[0148] Plan 5

[0149] In one embodiment, when the second water level information indicates that the water level in the chamber 111 has reached the water level line corresponding to the location of the second water level detection element 22, the control module is configured to determine that the water level in the chamber 111 has reached the lower limit water level in response to the current TDS value being ≥ the second preset TDS value and the water purifier 100 continuing to produce water for the third preset water production duration. Specifically, when the water level in the chamber 111 reaches the water level line corresponding to the location of the second water level detection element 22, if the current TDS value is ≥ the second preset TDS value at this time, indicating that the water quality of the remaining water in the raw water tank 11 is poor, the control module controls the water purifier 100 to continue producing water until the third preset water production duration is reached, at which point the water level in the chamber 111 reaches the lower limit water level, controls the water purifier 100 to stop producing water, and issues a water shortage reminder.

[0150] Plan 6

[0151] In one embodiment, when the second water level information indicates that the water level in the chamber 111 has reached the water level line corresponding to the location of the second water level detection element 22, the control module is configured to determine that the water level in the chamber 111 has reached the lower limit water level in response to the current TDS value being ≥ the second preset TDS value and the water purifier 100 continuing to produce water until the current TDS value is greater than the first preset TDS value. Specifically, if the first preset TDS value is ≥ the current TDS value ≥ the second preset TDS value, indicating that the current water quality is acceptable, the water purifier 100 may continue to produce water until the current TDS value is greater than the first preset TDS value, indicating that the current water quality is poor. At this point, the water level in the chamber 111 reaches the lower limit water level, and the water purifier 100 is controlled to stop producing water and issue a water shortage reminder.

[0152] The water purifier 100 of this solution can execute any of the above solutions according to the current water level and the current TDS value.

[0153] When the water level detection mechanism 2 fails or an abnormal situation such as a filter blockage in the purification mechanism occurs, the water in the chamber 111 will be lower than the first water level detection element 21 and the water production process is still in progress. The second water level information obtained by the second water level detection element 22 has not yet indicated that the water level in the chamber 111 has reached the water level line corresponding to the location of the second water level detection element 22. The water quality in the chamber 111 may have deteriorated and water production cannot continue. In this embodiment, when the first water level information indicates that the water level in the chamber 111 has reached the water level line corresponding to the location of the first water level detection element 21, the control module is used to respond to the water purifier 100 to continue water production until the fourth preset water production time is reached and the second water level information indicates that the current water level in the chamber 111 has not reached the water level line corresponding to the location of the second water level detection element 22, and determine that the water level in the chamber 111 has reached the water level line corresponding to the location of the second water level detection element 22. In this solution, there are two triggering conditions for indicating that the current water level in the storage chamber 111 has reached the water level line corresponding to the position of the second water level detection element 22. The first is that during normal use of the water purifier 100, the water level is determined by the second water level detection element 22; the second is that when the water purifier 100 encounters an abnormal condition and continues to produce water for a period of time as long as the fourth preset water production period, the water level in the raw water tank 11 must have reached or even fallen below the water level line corresponding to the position of the second water level detection element 22, and the second water level information indicates that the current water level in the storage chamber 111 has not yet reached the water level line corresponding to the position of the second water level detection element 22. The control module determines that the water level in the storage chamber 111 has reached the water level line corresponding to the position of the second water level detection element 22, so as to ensure that a water shortage reminder indication can be issued in time and water production can be stopped to ensure healthy drinking water.

[0154] In one embodiment, if Figures 13 to 15 As shown, the water purifier 100 further includes a light assembly 4 .

[0155] When the current TDS value is ≥ the first preset TDS value, the lamp assembly 4 executes the first lighting mode to indicate that the water purifier 100 is in the water making state; the lamp assembly 4 executes the second lighting mode to indicate that the water purifier 100 is in the water shortage state of the raw water tank.

[0156] When the current TDS value is less than the first preset TDS value, the light assembly 4 executes the third lighting mode to indicate that the water purifier 100 is in the water making state; the light assembly 4 executes the fourth lighting mode to indicate that the water purifier 100 is in the water shortage state of the raw water tank.

[0157] In one embodiment, the first lighting mode and the third lighting mode are constant lighting modes of the first light, and the second lighting mode and the fourth lighting mode are flashing modes of the first light, so as to distinguish and indicate the water production state and the water shortage state of the raw water tank.

[0158] In one embodiment, the first and second lighting modes of the light assembly 4 have the same color, the third and fourth lighting modes have the same color, and the first and third lighting modes have different colors. In one specific embodiment, when the current TDS value is ≥ the first preset TDS value, if the water purifier 100 is in the water production state, the light assembly 4 displays a solid red light mode. If the water purifier 100 is in the raw water tank water shortage state, the light assembly 4 displays a flashing red light mode. Because the water quality in the raw water tank 11 is already poor, a red light is used for this indication, as the red light is more eye-catching. When the current TDS value is < the first preset TDS value, if the water purifier 100 is in the water production state, the light assembly 4 displays a solid blue light mode. If the water purifier 100 is in the raw water tank water shortage state, the light assembly 4 displays a flashing blue light mode.

[0159] In one embodiment, the water purifier 100 further includes a sound alarm (not shown in the figure); the sound alarm emits an alarm sound to indicate that the water purifier 100 is in a water shortage state in the raw water tank, which can more effectively remind the user.

[0160] In one embodiment, the first water level detection element 21 and the second water level detection element 22 are both liquid level sensors (such as reed switches). Figure 2 As shown, the water level detection mechanism 2 also includes a float 23, which is located within the chamber 111. The float 23 moves downward along with the water level in the raw water tank 11. When the float 23 drops along with the water level to the water level line corresponding to the location of the first water level detection element 21, the first water level detection element 21 obtains the position information of the float 23, i.e., obtains the first water level information. When the float 23 drops along with the water level to the water level line corresponding to the location of the second water level detection element 22, the second water level detection element 22 obtains the position information of the float 23, i.e., obtains the second water level information.

[0161] Furthermore, the liquid level sensors are respectively installed on the filter element holder 51. Specifically, the raw water tank 11 can be taken down to receive water when replenishing raw water, such as Figure 2 and Figure 7 As shown, the first water level detection element 21 and the second water level detection element 22 are installed on the filter element frame 51. Compared with the solution of installing them in the raw water tank 11, it is convenient for the first water level detection element 21 and the second water level detection element 22 to be electrically connected to the control module.

[0162] Further, if Figure 2 and Figure 3As shown, a mounting box 112 is provided in the raw water tank 11, and the float 23 is located in the mounting box 112 so as to float up and down. The mounting box 112 is a hollow structure, and the water in the cavity 111 can enter the mounting box 112. The float 23 is installed through the mounting box 112, and the inner wall of the mounting box 112 can also limit the floating space of the float 23.

[0163] In one embodiment, if Figures 1 to 4 As shown, the inner wall of the raw water tank 11 is provided with a support platform 113 and two opposing engaging portions 114. Bosses 1121 are provided on either side of the mounting box 112. Both sides of the mounting box 112 engage the engaging portions 114 via the bosses 1121, and the bottom wall of the mounting box 112 is supported on the support platforms 113. Furthermore, the inner wall of the raw water tank 11 is provided with a limiting rib 115. The limiting rib 115 abuts against the top wall of the mounting box 112 to limit the upward movement of the mounting box 112. Furthermore, by limiting the size of the limiting rib 115 protruding from the inner wall of the mounting box 112, the user can attach and detach the mounting box 112 by applying a certain amount of force. If the float 23 is damaged or needs to be cleaned, the mounting box 112 can be removed and replaced.

[0164] In one embodiment, if Figure 1 and Figure 2 As shown, two mounting seats 516 are provided on the outer wall of the filter element holder 51 facing the raw water tank 11 . The two mounting seats 516 are distributed sequentially from top to bottom, and the first water level detection element 21 and the second water level detection element 22 are installed on the corresponding mounting seats 516 in a one-to-one correspondence.

[0165] In one embodiment, if Figure 7 As shown, the water purifier 100 also includes an in-place detection element 731 (such as a reed switch) and an in-place magnet (not shown in the figure). The in-place detection element 731 is installed on the outer wall of the filter element holder 51 on the side facing the raw water tank 11, and the in-place magnet is installed on the outer wall of the raw water tank 11 on the side facing the in-place detection element 731. The in-place detection element 731 cooperates with the in-place magnet to detect whether the raw water tank 11 is installed in place.

[0166] In one embodiment, if Figure 1 、 Figure 16 and Figure 17As shown, the water purifier 100 also includes a casing 52, a clean water tank 12, a kettle (not shown in the figure) and a water collecting box 13. The casing 52 constitutes part of the outer contour structure of the water purifier 100. The casing 52 is provided with a first water supply port 521 and a second water supply port 522. The clean water tank 12 is used to store clean water treated by the purification mechanism. The clean water tank 12 is detachably installed in the casing 52. The kettle is placed below the second water supply port 522. The kettle is used to hold drinking water supplied by the second water supply port 522 and can perform secondary heating on the water held in the kettle. The water collecting box 13 is provided with a first water collecting port 131 and a water collecting chamber 132 that are connected to each other. The first water supply port 521 is located above the first water collecting port 131. When using the water purifier 100, the user can take a cup to collect water from the first water supply port 521 and use it whenever he wants. The user can also first collect water from the second water supply port 522 through the kettle, and then use the water collected by the kettle and the health-promoting ingredients (tea, dendrobium, etc.) put into the kettle to cook, etc. Then, when the user needs to take a cup to collect water, the user can pour the liquid in the kettle into the cup, which is convenient to use.

[0167] In one embodiment, as shown in FIG6 , the top wall of the housing 52 is provided with an assembly opening 523 , and the clean water tank 12 is inserted into the housing 52 through the assembly opening 523 , making it easy to take the clean water tank 12 in and out.

[0168] Further, if Figure 17 As shown, the top wall of the purified water tank 12 is flush with the top wall of the housing 52 to improve the aesthetics of the top wall profile of the purified water machine 100.

[0169] Further, if Figure 17 As shown, a gripping portion 121 is provided on the top wall of the clean water tank 12 . The gripping portion 121 is groove-shaped for a user to grip the clean water tank 12 .

[0170] In one embodiment, if Figure 1 and Figure 13 As shown, the water purifier 100 also includes a waterway plate 32, which is located below the raw water tank 11. The housing 52 and the raw water tank 11 are arranged in a left-right direction, and the kettle and water collection box 13 are both located in front of the housing 52. The waterway plate 32 is provided with multiple flow channels, flow channel inlets, and flow channel outlets, which are used to connect the raw water tank 11 with the water channel in the housing 52.

[0171] In one embodiment, if Figure 5 、 Figure 6 、 Figure 13 and Figure 17 As shown, the water purifier 100 includes a base 53 and a raw water tank seat 54. The raw water tank seat 54 is covered on the outer periphery of the waterway plate 32. The raw water tank 11 is placed on the raw water tank seat 54. The casing 52 and the raw water tank seat 54 are arranged in sequence in the left and right directions and are respectively installed on the base 53.

[0172] In one embodiment, if Figure 9 As shown, the water purifier 100 also includes a communicating vessel 33, a first water inlet end of the communicating vessel 33 is connected to the clean water outlet of the purification mechanism through a second pipe 64, and a water outlet end of the communicating vessel 33 is connected to the clean water tank 12, and the purified water flowing out of the rear filter element of the purification mechanism is transported to the clean water tank 12 through the communicating vessel 33 for temporary storage.

[0173] Further, if Figure 10 and Figure 11 As shown, the manifold 33 extends in the vertical direction and is located between the clean water tank 12 and the filter cartridge holder 51. The manifold 33 is relatively small in the front-to-back direction, which facilitates the compact arrangement of the clean water tank 12, the manifold 33, and the filter cartridge holder 51 from the front to the back. The manifold 33 includes a first interface 331 and a second interface 332. The first interface 331 is connected to the second pipe 64 to form the first water inlet end of the manifold 33, and the second interface 332 is connected to the clean water tank 12 to form the water outlet end of the manifold 33. Figure 12 As shown, the chamber of the manifold 33 is equipped with a high-level float 335 and a low-level float 336. An overflow prevention reed switch 337 is installed on the outside of the manifold 33 to monitor the water level within the manifold 33. A high-level detector and a low-level detector (not shown) are also installed on the outside of the manifold 22. When the high-level detector fails to detect the high-level float 335, the water purifier 100 begins water production. The technology used by the water purifier to initiate water production based on the detection of the floats and the water level detector is well known in the art and will not be further described in detail herein.

[0174] Further, if Figure 7 and Figure 8 As shown, the water purifier 100 also includes a heating assembly 34, a first valve 35, a first pipeline 61, and a second valve 36. The water inlet of the heating assembly 34 is connected to the water outlet of the clean water tank 12. The heating assembly 34 is used to heat the water output from the clean water tank 12 to supply hot water. The water inlet of the first valve 35 is connected to the water outlet of the heating assembly 34. The first water outlet of the first valve 35 is connected to the first water supply port 521. The water inlet of the first pipeline 61 is connected to the second water outlet of the first valve 35. The water inlet of the second valve 36 is connected to the water outlet of the first pipeline 61. The first water outlet of the second valve 36 is connected to the second water supply port 522.

[0175] like Figure 7 、 Figure 8 and Figure 17As shown, the raw water tank 11, waterway plate 32, purification mechanism, manifold 33, clean water tank 12, heating assembly 34, first valve 35, and first water supply port 521 are sequentially connected to form a first water supply path. The raw water tank 11, waterway plate 32, purification mechanism, manifold 33, clean water tank 12, heating assembly 34, first valve 35, first pipeline 61, second valve 36, and second water supply port 522 are sequentially connected to form a second water supply path. Water in the raw water tank 11 flows into the purification mechanism via the waterway plate 32. Purified water after purification by the purification mechanism is poured into the clean water tank 12 through the manifold 33 for temporary storage. When a user uses a cup to draw water from the first water supply port 521, the purified water in the clean water tank 12 flows through the heating assembly 34 and first valve 35 in sequence before being supplied to the cup via the first water supply port 521. When a kettle is used to draw water, the purified water in the clean water tank 12 flows through the heating component 34 , the first valve 35 , the first pipeline 61 and the second valve 36 in sequence, and is then supplied to the kettle through the second water supply port 522 .

[0176] Further, if Figure 8 and Figure 10 As shown, the second water outlet of the second valve 36 is connected to the second water inlet of the manifold 33. When the water purifier 100 has been in an unused state for a predetermined standby time, the clean water tank 12, the heating assembly 34, the first valve 35, the first pipe 61, the second valve 36, the manifold 33, and the clean water tank 12 are sequentially connected to form a circulating water circuit. The circulating water circuit is then operated. After being heated by the heating assembly 34, the water in the clean water tank 12 flows sequentially through the first valve 35, the first pipe 61, the second valve 36, the manifold 33, and then flows back into the clean water tank 12 for hot water sterilization to prevent bacterial growth in the water circuit.

[0177] Further, if Figure 10 and Figure 11 As shown, a drain valve body 37 is provided outside the clean water tank 12 and the two are in communication. The drain valve body 37 is connected to the second interface 332 of the communicating vessel 33. A diaphragm pump 38 is provided on the pipeline between the heating assembly 34 and the drain valve body 37. Specifically, the drain valve body 37 is connected to the inlet of the diaphragm pump 38 through a third pipeline 65, the outlet of the diaphragm pump 38 is connected to the heating assembly 34 through a fourth pipeline 66, and the outlet of the heating assembly 34 is connected to the first valve 35 through a fifth pipeline 67. When making water, the water purified by the purification mechanism enters the clean water tank 12 through the communicating vessel 33 and the drain valve body 37 in sequence. When the water purifier 100 supplies water, the clean water tank 12 and the heating component 34 are connected through the drain valve body 37 and the diaphragm pump 38 connected in sequence. Under the power provided by the diaphragm pump 38, the purified water in the clean water tank 12 flows through the drain valve body 37, the third pipeline 65, the diaphragm pump 38, the fourth pipeline 66, the heating component 34, the fifth pipeline 67 and the first valve 35 in sequence.

[0178] In one embodiment, if Figures 8 to 11 As shown, the communicating vessel 33 also includes a reflux inlet 333, which is connected to the second valve 36 through the sixth pipeline 68. When the time for which the water purifier 100 is not in use reaches the preset standby time, the clean water tank 12, the drain valve body 37, the third pipeline 65, the diaphragm pump 38, the fourth pipeline 66, the heating component 34, the fifth pipeline 67, the first valve 35, the first pipeline 61, the second valve 36, the sixth pipeline 68, the communicating vessel 33, the drain valve body 37 and the clean water tank 12 are connected in sequence to form a circulating water circuit, and the corresponding pipelines and components on the pipelines are sterilized by hot water.

[0179] It should be noted that the water inlet of the first valve 35 is selectively connected to its first water outlet and the second water outlet to supply water to the first water supply port 521, or connected to the water inlet of the second valve 36; for example, when the first water supply port 521 needs to discharge water, the water inlet of the first valve 35 is connected to its first water outlet, and is not connected to its second water outlet. The water inlet of the second valve 36 is selectively connected to its first water outlet and the second water outlet to supply water to the second water supply port 522, or is connected to its second water outlet. For example, when the second water supply port 522 needs to discharge water, the water inlet of the first valve 35 is connected to its second water outlet, and the water inlet of the second valve 36 is connected to its first water outlet. For another example, when water sterilization is performed, the water inlet of the first valve 35 is connected to its second water outlet, and the water inlet of the second valve 36 is connected to its second water outlet.

[0180] In one embodiment, if Figure 8 and Figure 9 As shown, a water vapor separation component 39 is provided between the first water outlet end of the first valve 35 and the first water supply port 521. The water flowing out of the first water outlet end of the first valve 35 is subjected to water vapor separation treatment by the water vapor separation component 39 and then flows to the first water supply port 521, thereby avoiding excessive gas in the water flow output from the first water supply port 521, which may cause water splashing and affect the user experience.

[0181] Further, if Figure 10 and Figure 11 As shown, the communicating vessel 33 further includes an air inlet 334 , and the exhaust port of the water vapor separation component 39 is connected to the air inlet 334 of the communicating vessel 33 through the seventh pipeline 69 , and the communicating vessel 33 is connected to the atmosphere.

[0182] In one embodiment, Figures 7 to 11As shown, the second valve 36 and the first valve 35 are arranged spaced apart along the left and right directions of the water purifier 100, and the second valve 36 and the first valve 35 are both located between the clean water tank 12 and the booster pump 31, the reflux inlet 333 is provided on the left side wall of the communicating vessel 33, and the air inlet 334 is provided on the right side wall of the communicating vessel 334, one end of the sixth pipeline 68 is connected to the reflux inlet 333, and the other end extends from the left side of the clean water tank 12 and then extends to the bottom of the clean water tank 12 and is connected to the second valve 36, one end of the seventh pipeline 69 is connected to the air inlet 334, and the other end extends from the right side of the clean water tank 12 and then extends to the front of the clean water tank 12 and is connected to the water vapor separation component 39. The components are arranged compactly, which is conducive to reducing the overall size of the water purifier 100.

[0183] In one embodiment, if Figure 8 As shown, the water purifier 100 includes a fixed shell 55, the booster pump 31 is placed vertically and fixed in the fixed shell 55, the booster pump 31 partially extends out of the bottom wall of the fixed shell 55, the clean water tank 12 is located above the fixed shell 55, and the first raw water pipeline 621, the second raw water pipeline 622 and the concentrated water output pipeline 63 are located below the fixed shell 31.

[0184] In one embodiment, if Figure 13 and Figure 17 As shown, an extension seat 531 is provided on the front side of the base 53, and the kettle is placed on the extension seat 531; the water collecting box 13 is against a side wall of the extension seat 531, and the two together form the base structure of the water purifier 100.

[0185] In one embodiment, if Figure 17 As shown, the base 53 is provided with a lower coupler 532, and the kettle is provided with an upper coupler, which is electrically connected to the lower coupler 532 to perform secondary heating on the water in the kettle.

[0186] Further, if Figure 17 As shown, the housing 52 is provided with a display screen 524, which is used to display the working status of the kettle, including but not limited to the current water temperature and the current water level of the kettle. For easy viewing, the display screen 524 is installed in the front of the housing 52, and the display screen 524 is tilted so as to face the user.

[0187] In one embodiment, if Figure 6 、 Figure 17 As shown, a selection switch 525 is provided on the housing 52 . The selection switch 525 is provided below the display screen 524 . The selection switch 525 can be used to trigger water flow from the second water supply port 522 .

[0188] In one embodiment, a power module (not shown) is provided in the housing 52 to power the kettle. Of course, the kettle can be used directly by plugging in the power module without providing the power module.

[0189] In one embodiment, if Figure 16 and Figure 17 As shown, the water collection box 13 is provided with a placement portion 133 and a second water collection port 134. The placement portion 133 is located on the other side of the first water collection port 131 away from the placement position of the kettle. The placement portion 133 is used to place a water cup. When the user needs to use the water in the kettle, the cup is placed on the placement portion 133 before operating the kettle to pour water. This prevents the first water supply port 521 or the second water supply port 522 from interfering with the kettle's pouring operation. The second water collection port 134 is connected to the water collection chamber 132, so that any water spillage during the pouring process can be collected promptly.

[0190] Further, if Figure 16 As shown, the placement portion 133 is a concave structure, which is convenient for the user to place it accurately.

[0191] In one embodiment, if Figures 13 to 15 As shown, the light assembly 4 is located below the raw water tank 11, and the raw water tank 11 is provided with a first light-transmitting window. In this way, the user can observe the display of the light assembly 4 through the first light-transmitting window to understand the water production status of the water purifier 100 and the water shortage status of the raw water tank.

[0192] Furthermore, the raw water tank 11 is a light-transmitting structure, which has an aesthetically pleasing overall appearance and is easy to process. When the raw water tank is made of a light-transmitting material, the light-transmitting window may not be provided because the raw water tank itself is light-transmitting.

[0193] In one embodiment, if Figure 15 As shown, the light assembly 4 is located between the raw water tank 11 and the waterway plate 32. Utilizing the free space between the raw water tank 11 and the waterway plate 32 to accommodate the light assembly 4 contributes to a more compact structure for the water purifier 100. Preferably, the raw water tank seat 54 is a cover structure that is positioned around the outer periphery of the waterway plate 32, with the light assembly 4 positioned between the waterway plate 32 and the raw water tank seat 54.

[0194] Further, if Figure 14 and Figure 15 As shown, the lamp assembly 4 is detachably connected to the waterway plate 32. When the lamp assembly 4 fails, it can be removed for maintenance or replacement.

[0195] Furthermore, the connection method between the lamp assembly 4 and the waterway plate 32 includes snap connection, buckle connection or adsorption connection, which has a simple structure and is quick to assemble and disassemble.

[0196] In one embodiment, if Figure 15As shown, the lamp assembly 4 includes a box body 41, a lamp board 42 and a lamp bead 43. The box body 41 is detachably connected to the waterway plate 32 and the box body 41 is provided with a second light-transmitting window. The box body 41 is open on one side of the waterway plate 32. The lamp board 42 is assembled in the box body 41 from the opening. The lamp bead 43 is connected to the lamp board 42. The lamp bead 43 is used to emit indicator light. The light passes through the second light-transmitting window and the first light-transmitting window in turn to be displayed outward.

[0197] Further, if Figure 13 and Figure 15 As shown, the raw water tank base 54 has a through-hole 541. The top of the box body 41 is inserted into the through-hole 541, and the connection between the two is sealed by a sealing ring 71. Specifically, to enhance the aesthetics of the water purifier 100, the raw water tank base 54 is not light-transmissive, thereby obscuring the outline of the waterway plate 32. The light assembly 4 emits light from the through-hole 541 of the raw water tank base 54 to the raw water tank 11.

[0198] Further, if Figures 13 to 15 As shown, the upper surface of the box body 41 is provided with a raised portion 411, which is inserted into the through hole 541. The raised portion 411 cooperates with the through hole 541 and also serves as a positioning function. The raised portion 411 also forms a second light-transmitting window of the box body 41. Light emitted by the lamp 43 located in the box body 41 is transmitted through the raised portion 411 to the raw water tank 11.

[0199] In one embodiment, if Figure 14 and Figure 15 As shown, the upper surface of the waterway plate 32 is provided with two oppositely arranged support ribs 321, the support ribs 321 are provided with buckling grooves 3211, and the box body 41 is provided with two oppositely arranged buckling parts 412, and the buckling grooves 3211 and the buckling parts 412 are buckled one by one.

[0200] Further, if Figure 14 As shown, two extension ribs 413 are provided on one side of the box body 41. When the box body 41 is assembled on the waterway plate 32, the two extension ribs 413 are opposite to the two sides of one of the support ribs 321 of the waterway plate 32 to play a positioning role.

[0201] In one embodiment, the box body 41 is a light-transmitting structure, and there is no need to provide a separate light-transmitting window, which facilitates assembly.

Various modifications and variations may be made to the above embodiments without departing from the scope of the present disclosure. Similarly, the various technical features of the above embodiments may be arbitrarily combined to form additional embodiments of the present invention that may not be explicitly described.
