Referring to fig. 1 to 7, according to an embodiment of the present invention, a water purifying apparatus is provided, which includes a housing 501, a first mounting seat 116, and a raw water tank 105. The first mounting seat 116 is fixed to the top of the housing 501, and the first mounting seat 116 is provided with a water inlet 112; the raw water tank 105 is detachably mounted on the first mounting seat 116, the raw water tank 105 comprises a water inlet 204, a first valve assembly is arranged at the water inlet 204, and when the raw water tank 105 leaves the first mounting seat 116, the first valve assembly closes the water inlet 204; when the raw water tank 105 is mounted on the first mounting seat 116, the water inlet 204 is communicated with the water inlet interface 112.

This kind of water purification equipment sets up former water tank 105 in the top of casing 501, and it is convenient more and accord with people's custom to it adorns water to fall water to can conveniently observe the water level condition in the middle of former water tank 105. Wherein, when needs adorn water or pour water, can take off former water tank 105 from first mount pad 116, need not any unnecessary action, and then conveniently remove former water tank 105 and take water to any place that has clean water source, also can remove former water tank 105 to any place that conveniently pours water. The first valve assembly is arranged at the water inlet 204 at the bottom of the raw water tank 105, and when the raw water tank 105 is mounted on the first mounting seat 116, the first valve assembly is opened, so that the communication between the water inlet 204 and the water inlet interface 112 is not affected, and the water in the raw water tank 105 can enter subsequent parts of the water purifying equipment through the water inlet interface 112. When the raw water tank 105 leaves the first mounting seat 116, the water inlet 204 at the bottom of the raw water tank 105 is closed by the first valve assembly, so as to prevent water in the raw water tank 105 from leaking.

Referring to fig. 1 and 2, a concentrate tank 102 is disposed in the raw water tank 105, the concentrate tank 102 includes a drain pipe 201, a drain port 202 is formed at the bottom of the raw water tank 105 and is communicated with the drain pipe 201, a drain port 113 is disposed on the first mounting seat 116, and a second valve assembly is disposed at the drain port 202. The raw water tank 105 is removed from the first mounting seat 116 and the second valve assembly closes the drain port 202; the raw water tank 105 is mounted on the first mounting seat 116, and the drain port 202 communicates with the drain port 113.

Because the concentrated water tank 102 is arranged inside the raw water tank 105, the occupied space of the water purifying equipment can be saved, and the volume of the water purifying equipment is reduced. Further, the raw water tank 105 is detachably attached to the first attachment seat 116, and the concentrated water tank 102 is also detachably attached to the first attachment seat 116. Therefore, the water receiving of the raw water tank 105 and the water pouring of the concentrated water tank 102 can be completed in the same process, the operation time is saved, and the use experience is improved.

Of course, the concentrate tank 102 is not necessarily disposed inside the raw water tank 105, for example, the concentrate tank 102 may be disposed independently of the raw water tank 105, and in this case, the raw water tank 105 is not connected to the concentrate tank 102, and the concentrate tank 102 may be drained separately.

Further, when the concentrate tank 102 is disposed in the raw water tank 105, the raw water tank 105 is detachable from the concentrate tank 102. In this case, the concentrated water tank 102 and the raw water tank 105 are more conveniently and sufficiently cleaned. Specifically, in order to clean the raw water tank 105 or the concentrated water tank 102, the concentrated water tank 102 may be detached from the raw water tank 105. Furthermore, since the concentrate tank 102 is detachable with respect to the raw water tank 105, when the raw water still exists in the raw water tank 105 but the concentrate tank 102 is full of water, the concentrate tank 102 can be detached alone to pour out the concentrate.

When the concentrated water tank 102 is detachable with respect to the raw water tank 105, a snap is formed on a side wall of the concentrated water tank 102, and a snap groove matched with the snap is formed on the raw water tank 105. Furthermore, when the concentrated water tank 102 enters the raw water tank 105, the fastener enters the slot and is fastened under the action of gravity. Even if the concentrated water tank 102 is subjected to the buoyancy of the raw water tank 105, the engagement between the snap and the locking groove can prevent the concentrated water tank 102 from being separated from the raw water tank 105.

Further, the opening of the raw water tank 105 further comprises a top cover 101, wherein the top cover 101 is detachably mounted at the opening of the raw water tank 105, so that the water in the raw water tank 105 can be conveniently injected, and the concentrated water in the concentrated water tank 102 can be conveniently discharged.

According to the embodiment of the present invention, the first end of the drain pipe 201 is located inside the concentrated water tank 102, and the first end of the drain pipe 201 is formed with the water outlet 601, and the height of the water outlet 601 is not lower than the highest water level of the raw water tank 105.

Since the height of the water outlet 601 is not lower than the highest water level of the raw water tank 105, raw water in the raw water tank 105 can be prevented from flowing into the concentrated water tank 102 under the action of a water level difference, and waste of water resources is prevented. Furthermore, since the first end of the drain pipe 201 where the water outlet 601 is located inside the concentrated water tank 102, the concentrated water in the concentrated water tank 102 can be prevented from flowing back to the raw water tank 105.

Further, the height of the water outlet 601 is higher than the highest water level of the raw water tank 105, so as to better prevent the raw water in the raw water tank 105 from entering the concentrated water tank 102.

Referring to fig. 3 and 4, an annular groove is formed on the outer surface of the second end of the drainage pipe 201, the first sealing ring 108 is installed in the annular groove, and the first sealing ring 108 is in interference fit with the inner surface of the drainage port 202. Further, the first packing 108 ensures a tight connection between the drain pipe 201 and the drain port 202, thereby preventing leakage between the concentrate tank 102 and the raw water tank 105.

When the drain pipe 201 and the drain port 202 are both symmetrical, the outer surface of the second end of the drain pipe 201 is inclined away from the center line of the drain pipe 201 along the direction close to the drain port 202. Correspondingly, the inner surface of the drain opening 202 is inclined toward the center line of the drain opening 202 in the direction toward the drain pipe 201. In this case, the drain pipe 201 and the drain port 202 have a certain clamping locking function, and the elastic first sealing ring 108 is disposed on the outer surface of the drain pipe 201, so that the sealing effect between the drain pipe 201 and the drain port 202 can be fully ensured.

In addition, be formed with handheld portion in former water tank 105 outside both sides, and handheld portion corresponds and distributes in the left and right sides of fig. 2, and under this kind of condition, the in-process that holds the water tank set spare can be avoided in the setting of handheld portion, and the water tank set spare takes place to rock. Wherein the hand-held portion may be a recessed structure 401 formed on the raw water tank 105.

A first sensor 114 is disposed at the bottom of the first mounting seat 116. Further, the water purification apparatus further includes a water pump 603 and a controller. The water pump 603 pumps water from the raw water tank 105 into the housing 501, specifically, into a member (e.g., the filter element 504) inside the housing 501. The controller is connected to the first sensor 114, and when the first sensor 114 detects that the raw water tank 105 is separated from the first mounting seat 116, the controller controls the water pump 603 to be turned off.

Since the water path between the raw water tank 105 and the internal components of the housing 501 is cut off when the raw water tank 105 is separated from the first mounting seat 116, if the water pump 603 continues to operate, a large noise may be generated due to idling, and a large loss may be generated in the water purifying apparatus. In this case, by setting the first sensor 114, whether the raw water tank 105 is mounted on the first mounting seat 116 can be accurately monitored, and whether the waterway of the water purifying apparatus is conducted can be determined. When the first sensor 114 detects that the raw water tank 105 is separated from the first mounting seat 116, the water pump 603 is turned off to protect the water purifying apparatus.

According to one embodiment of the present invention, the raw water tank 105 is provided with a mounting groove at the bottom thereof, and the first sensing member is fixed in the mounting groove. For example, the first sensing component is a magnetic member and the first sensor 114 is a hall sensor. Because the first magnetic part is arranged in the mounting groove at the bottom of the raw water tank 105, and further cannot be seen from the outside, the attractiveness of the water purifying equipment can be ensured. Moreover, the mounting groove can protect the magnetic part, and the magnetic part is prevented from being damaged in the process of dismounting the raw water tank 105. In addition, because the first sensor 114 is located at the bottom of the first mounting seat 116, the first sensor 114 can be prevented from being damaged by abrasion in the process of disassembling and assembling the raw water tank 105.

Wherein the magnetic member may, but need not, take the form of a magnet 118. The first sensor 114 is a hall sensor, and can sense the change of the magnetic field around the first sensor, and when the raw water tank 105 carries the magnet 118 to be far away from or close to the hall sensor, the hall sensor can sense and send the change to the controller in time. Wherein the first sensor 114 may, but need not, be disposed directly below the magnet 118.

For example, the hall sensor may include a spring plate and a circuit that are matched with the magnet 118, and when the magnet 118 moves away from or approaches the spring plate, the spring plate springs up, and the current of the circuit changes. Of course, the specific type of hall sensor is not limited by the examples herein.

It should be noted that the type of the first sensor 114 is not limited herein. For example, the first sensor 114 may also be a gravity sensor or an infrared sensor. When the first sensor 114 is a gravity sensor, it is determined whether the raw water tank 105 is separated from the first mounting seat 116 by sensing a change of gravity on the first mounting seat 116. When the first sensor 114 is an infrared sensor, it is determined whether the raw water tank 105 is separated from the first mounting seat 116 by sensing a change of infrared light above the first mounting seat 116. When the first sensor 114 is of another type, a corresponding first sensing component may be correspondingly disposed at the bottom of the raw water tank 105, and the first sensor 114 may determine the position of the raw water tank 105 by sensing the first sensing component.

Further, the water purifying apparatus further includes a second sensor 115. In order to prevent the second sensor 115 from being damaged by abrasion during the assembly and disassembly process, the second sensor 115 is fixed at the bottom of the first mounting seat 116. The controller is connected with the second sensor 115, and when the raw water tank 105 is installed on the first installation seat 116, the controller controls the second sensor 115 to be started; on the basis, when the second sensor 115 detects that the water level in the raw water tank 105 is lower than the set water level, the controller controls the water pump 603 to be turned off. That is, the water level in the raw water tank 105 is further detected only when the first sensor 114 detects that the raw water tank 105 is mounted to the first mounting seat 116.

When the second sensor 115 detects that the water level in the raw water tank 105 is lower than the set water level, it indicates that the raw water tank 105 is lack of water, and at this time, the controller sends the water shortage information to the display panel 507 of the water purifying device, and the display panel 507 prompts water shortage. The set water level here may be zero or may also be near zero. To use up the raw water tank 105, a delay period may be set, for example, when the second sensor 115 detects that the water level in the raw water tank 105 is lower than the set water level, the water pump 603 continues to operate for the delay period and then is turned off. The delay time can be one minute, and of course, other time can be used, and the delay time can be specifically designed according to the set water level and the water production speed of the water purification equipment.

Referring to fig. 2, a float groove extending in a height direction of the raw water tank 105 is provided in the raw water tank 105, a float stopper 107 is provided at a top of the float groove, a float space of the float 106 is defined between the float groove and the float stopper 107, and the float 106 is installed in the float space. Further, as the water level in the raw water tank 105 changes, the position of the float 106 in the floating space also changes. The second sensor 115 judges whether the water level in the raw water tank 105 is lower than the set water level by detecting the position of the float 106. For example, when the float 106 sinks to the bottom of the float bowl, indicating that there is no water in the raw water tank 105, the second sensor 115 sends a corresponding signal to the controller. For another example, when the float 106 moves upward along the float groove and abuts against the float stopper 107, indicating that the water level in the raw water tank 105 has reached or exceeded the set water level, the second sensor 115 judges the water level in the raw water tank 105 by detecting the position of the float 106 and transmits it to the controller. Wherein the height of the float plug 107 corresponds to the set water level.

The first sensor 114 and the second sensor 115 may be fixed to the bottom of the first mounting seat 116 by a fastener 117.

It should be noted that, since it is not very important how much the actual water level in the raw water tank 105 is, in the process of controlling the water pump 603, it is only necessary to determine whether the actual water level in the raw water tank 105 reaches the set water level. Therefore, the arrangement of the float groove and the float plug 107 can well meet the above requirements. By providing the float groove and the float stopper 107, the relationship between the actual water level and the set water level in the raw water tank 105 can be accurately judged. And the structure of the float groove and the float plug 107 is simple, and is convenient to manufacture and maintain.

Referring to fig. 5, a water pump 603, a filter element 504, a clean water tank 505, and a heating device 506 are fixed inside a housing 501. Referring to fig. 6, the raw water pump 603 in the raw water tank 105 is fed to the filter element 504, the raw water is filtered by the filter element 504, the obtained pure water enters the pure water tank 505, and the concentrated water enters the concentrated water tank 102 from the filter element 504 through the control valve 602. The pure water in the pure water tank 505 may be directly fed into the water outlet nozzle of the water purifying apparatus to obtain normal temperature water at the water outlet nozzle, or may be fed into the heating device 506 to be heated by the heating device 506 and then fed into the water outlet nozzle to obtain high temperature water.

Further, a supporting member 503 is disposed inside the housing 501, and the supporting member 503 includes a base 5033, a fixing pillar 5032, and a second mounting seat 5031. The fixing post 5032 has a first end connected to the base 5033 and a second end connected to the second mounting seat 5031.

The plug 1041 may be, but need not be, a silica gel plug with good sealing effect. The resilient member 1042 may, but need not, employ a readily available spring. A round hole may be formed on the silicone plug, and the first end of the connecting shaft 1043 is inserted into the round hole on the silicone plug after passing through the spring.

In addition, the end surface of the first stopper 303 needs to be in sealing engagement with the plug 1041, so that the first stopper 303 is continuous along the inner surface of the water inlet 204 or the water outlet 202. The second blocking portion is used for limiting the elastic member 1042 and ensuring that the elastic member 1042 is located between the first blocking portion 303 and the second blocking portion, so there is no special requirement on the shape of the second blocking portion.

When the raw water tank 105 is mounted on the first mounting seat 116, the connecting shaft 1043 is jacked up, the elastic member 1042 is compressed, and the connecting shaft 1043 drives the plug 1041 to separate from the end face of the first stopper 303, so that the raw water tank 105 and the concentrated water tank 102 are communicated with the water path between the components inside the housing 501. The ends of the water inlet port 112 and the water outlet port 113 far away from the raw water tank 105 are communicated with other parts in the housing 501.

Further, as for the drainage port 202, a first limit surface of the drainage pipe 201 of the concentrated water tank 102 is formed on the bottom plate of the first annular assembling groove 301, thereby ensuring the assembly of the concentrated water tank 102 in the raw water tank 105. Similarly, for the water inlet 204, a second limiting surface of the filter assembly is formed on the bottom plate of the first annular assembling groove 301, so as to ensure the installation of the filter assembly.

It is found through fig. 3 that the filter assembly is arranged at the water inlet 204, so that the raw water is filtered by the filter assembly before entering the water pump 603, foreign matters carried in the raw water can be prevented from entering the water pump 603, the water pump 603 is prevented from losing efficacy, and the service life of the water purifying equipment is ensured.

According to an embodiment of the present invention, the filter assembly includes a cylindrical screen 1032 and a screen cover 1031, the cylindrical screen 1032 being mounted to a first end of the water inlet 204 and extending along a length direction of the water inlet 204; the filter screen cover 1031 is sleeved outside the cylindrical filter screen 1032, a liquid inlet of the siphon channel 207 is formed between the edge of the filter screen cover 1031 and the water inlet 204, a liquid outlet of the siphon channel 207 is formed at the second end of the water inlet 204, and the liquid level of the liquid outlet is lower than that of the liquid inlet, so that the siphon channel 207 passing through the cylindrical filter screen 1032 is formed between the liquid inlet and the liquid outlet.

Referring to fig. 2 and 3, the siphon channel 207 is indicated by a curve, wherein a starting point of the curve corresponds to an inlet of the siphon channel 207, an end point of the curve corresponds to an outlet of the siphon channel 207, and a direction of an arrow on the curve indicates a flowing direction of liquid in the siphon channel 207. It should be noted that, in the position shown in the section of fig. 3, the screen cover 1031 and the water inlet 204 are clamped, but a gap exists between the screen cover 1031 and the water inlet 204 along the periphery of the water inlet 204, and further, the siphon passage 207 is formed between the screen cover 1031 and the water inlet 204, between the screen cover 1031 and the tubular screen 1032, and inside the tubular screen 1032.
