Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

Fig. 1 is a schematic water path diagram of a desktop water purifier, and a booster pump 13 may pump raw water in a raw water tank 11 to a reverse osmosis filter element 14 for filtration. The raw water is filtered by the reverse osmosis filter element 14 to produce pure water, and the pure water can be stored in the pure water tank 15. When a user needs to use the water purifier, the pure water in the pure water tank 15 can be pumped to the water outlet end of the desktop water purifier through the water suction pump 16 for the user to use. The heating device 17 is arranged on a pipeline between the pure water tank 15 and the water outlet end. The heating device 17 is an instantaneous electric heater. The heating element of the heating device 17 is completely isolated from the water path, and the temperature of the water is gradually increased in the process of flowing in the pipeline, so that the heating device has the advantage of high heating speed. The user can set the temperature to obtain water at a desired temperature. The inventors have found that the pure water flow rate is related to the user-set temperature due to the limited heating power of the heating means 17. When the temperature of the pure water required by the user is lower, the water pump 16 pumps the pure water in the pure water tank 15 to the water outlet end at a larger flow rate; however, when the pure water temperature required by the user is high, the water pump 16 can only pump the pure water in the pure water tank 15 to the water outlet end at a small flow rate. For example, if the pure water flow rate through the pipe where the heating device 17 is located is within the range of 600-700L/min when the user sets the temperature to be 25 degrees, the pure water flow rate through the pipe where the heating device 17 is located is approximately within the range of 350-500L/min when the user sets the temperature to be 100 degrees. Also, the ambient temperature affects the pure water flow rate as well, and for example, the pure water in the pure water tank 15 is lower in winter than in summer, which makes it more difficult to heat to the set temperature. In order to ensure that the temperature of the pure water finally obtained by the user reaches the temperature set by the user, a flow control valve is required to be arranged in the desktop water purifier to control the flow of the pure water within a reasonable range. Therefore, even if a large-flux reverse osmosis filter element is adopted, the flow rate of pure water received by a user is still greatly limited. Therefore, the desktop water purifier cannot meet the requirement of a user on high-flow pure water. In addition, the arrangement of the flow control valve also leads to complex control logic, a large amount of experiments are needed to verify the relationship between the flow and the temperature, and the temperature is difficult to be accurately controlled due to the influence of environmental factors.

In order to solve the above problem, an embodiment of the utility model provides a desk-top purifier. The desktop water purifier is not only suitable for the existing desktop water purifier, but also suitable for any other desktop water purifiers. As shown in fig. 2 to 6, the desktop water purifier may include a water purifying body, a heating device 200, and a water storage device 300.

Optionally, the filter element assembly 140 includes, but is not limited to, one or more of a PP cotton filter element, an activated carbon filter element, an ultrafiltration membrane filter element, and a reverse osmosis filter element, or a composite filter element formed by combining any two or more of the above filter elements, and the composite filter element is not limited in the way of combining.

The water inlet end of the desktop water purifier can be communicated to the water inlet of the filter element assembly 140. Raw water can enter the filter element assembly 140 through the water inlet end of the desktop water purifier for filtration. Preferably, a water tank 100 may be further provided in the water purifying body. The water tank 100 may be communicated to the water inlet of the filter cartridge assembly 140. The water tank 100 may be used to store raw water to be filtered, such as tap water. Through setting up water tank 100, desktop purifier can need not to connect outside water route, and the experience of installation and use is better. Therefore, the desktop water purifier can be applied to any suitable place, and the application range is wider.

Optionally, a water path plate 150 may be further disposed within the water purification body, as shown in fig. 4-5. The water circuit board 150 may employ various types of water circuit boards known in the art or that may appear in the future. A water inlet solenoid valve 151, a waste water solenoid valve 153, a check valve 152, and other waterway components, which will be described later, may be provided on the waterway plate 150.

A user may add raw water to the water tank 100. In order to control the raw water, a water inlet solenoid valve 151 may be further provided in the water purification main body. The water inlet solenoid valve 151 may be provided on a pipe between the water outlet of the water tank 100 and the water inlet of the filter cartridge assembly 140. The water inlet solenoid valve 151 may employ various types of solenoid valves known in the art or that may occur in the future. The raw water may be filtered by the filter element assembly 140 to produce purified water.

The heating device 200 may be connected to the water purification body by any suitable means. The heating device 200 may be powered by the water purifying body. The water storage device 300 can be detachably mounted on the heating device 200 by any suitable means such as clamping, plugging and the like. That is, the water storage device 300 is removable from the water purifying body. The heating device 200 may be used to heat the water storage device 300. Preferably, the water storage means 300 may be a water bottle. The kettle may be of various types known in the art or that may occur in the future. The water outlet of the cartridge assembly 140 may be in communication with the water storage device 300 when the water storage device 300 is mounted on the heating device 200. That is, the purified water produced after the raw water is filtered by the filter element assembly 140 may flow out to the water storage device 300 through the water outlet of the filter element assembly 140. In order to prevent the purified water from flowing backward, the water purifying body may further include a check valve 152. A check valve 152 may be provided in the conduit between the outlet of the cartridge assembly 140 and the water storage device 300. Check valve 152 may be any of a variety of types known in the art or that may occur in the future. At this time, the heating device 200 may heat the water storage device 300, thereby increasing the temperature of the purified water in the water storage device 300.

In this way, the purified water produced after filtration by the filter element assembly 140 can be stored in the water storage device 300. The purified water is heated by the heating device 200 and then is available to the user. Therefore, the utility model discloses desk-top purifier need not to set up flow control valve and controls the water purification flow. That is, the water production capacity of the desktop water purifier may not be limited by the heating power of the heating device 200 and the ambient temperature, which is mainly determined by the water production capacity of the filter element assembly 140.

Thus, the filter element assembly 140 may employ a high flux filter element assembly. Typically, a filter cartridge assembly having a water production of greater than or equal to 400G (gallons) per day is referred to as a high flux filter cartridge assembly. Wherein 1G is approximately equal to 3.785 liters. High flux filter element assemblies are well known in the art and are not modified by the present invention and will not be described in detail.

Therefore, even if the user needs high-temperature purified water, the desktop water purifier can meet the use requirements of the user. Also, since the heating device 200 heats the static water in the water storage device 300, the temperature of the purified water in the water storage device 300 can be precisely controlled. In addition, if need also can set up the heat preservation function, like this when the user needs the water intaking, need not the time of waiting for the heating, the efficiency of water intaking is higher. Meanwhile, the water storage device 300 is detachable, so that a user can conveniently and directly take off the water storage device 300 to use the water storage device in other places, and the water storage device is very convenient and fast; the water storage device 300 is more convenient to clean when being taken down, so that the interior of the water storage device 300 is ensured to be clean, and purified water is prevented from being polluted; moreover, the water storage device 300 is convenient to repair and replace. Moreover, because a water pump is omitted, the secondary pollution of an intermediate link to purified water is reduced, and the noise and the power consumption are reduced; in addition, the volume of the desktop water purifier is reduced, and the cost is saved.

Preferably, as shown in fig. 3 to 6, the water tank 100 may be located at the rear of the water purifying body. The water storage device 300 may be located in front of the water purifying body. The filter cartridge assembly 140 may be located between the rear and the front, i.e., between the water tank 100 and the water storage device 300. So configured, the water tank 100 and the water storage device 300 can function as a housing to protect the filter element assembly 140. In addition, the internal structure of the desktop water purifier can be compact, and therefore the occupied space is small. Furthermore, the piping connections can be simplified.

Preferably, as shown in fig. 3 to 6, the water purifying body may be provided with a water intake 170. The outlet of the filter cartridge assembly 140 may be in communication with a water intake 170. The water intake 170 may be disposed directly above the water intake 301 of the water storage device 300. The water intake port 170 may be disposed spaced apart from the water intake port 301 of the water storage device 300. In this way, the purified water produced after being filtered by the filter element assembly 140 can flow out through the water intake 170 and be stored in the water storage device 300 through the water intake 301. Preferably, the water inlet 301 of the water storage device 300 may be funnel-shaped. This further facilitates the access of the purified water flowing out of the intake port 170, so that the purified water can be stored in the water storage device 300 through the intake port 301. And compared with a water inlet with a large size, the water inlet 301 can reduce the passage of dirt such as dust, thereby preventing the dirt from polluting the purified water in the water storage device 300.

When a user takes water, the clean water stored in the water storage device 300 can be taken out through the water inlet 301, or the water outlet 302 is provided on the water storage device 300, so that the clean water stored in the water storage device 300 can be taken out in a more comfortable manner. Through the arrangement, the desktop water purifier is simple in structure and low in production cost.

Optionally, the bottom of the water storage device 300 may also be provided with a water inlet, and a check valve is arranged at the water inlet. The water outlet of the filter element assembly 140 may be communicated to the water inlet of the bottom of the water storage device 300, so that purified water is stored in the water storage device 300.

Further, as shown in fig. 3 to 6, the water storage device 300 may include a pot body 310 and a pot lid 320. The lid 320 may be removably attached to the body 310 by any suitable means, such as snapping, or the like. The purified water produced after the filtration of the filter element assembly 140 may be stored in the kettle body 310. The water inlet 301 of the water storage device 300 may be disposed on the pot lid 320. With this arrangement, the water storage device 300 can be manufactured separately, thereby reducing the manufacturing difficulty. In addition, the inner part of the kettle body 310 can be cleaned more conveniently by detaching the kettle cover 320, so that the inner part of the kettle body 310 can be cleaned more conveniently, and purified water is prevented from being polluted.

Preferably, as shown in fig. 2-6, the heating device 200 may include a heating base 210 and a heating pan 220. The heating base 210 may be connected to the water purifying body by any suitable means, such as welding, gluing, integral molding, etc. The water storage means 300 may be installed on the heating base 210. The heating plate 220 may be disposed within the heating base 210. The heating pan 220 may be used to heat the water storage device 300. The heating base 210 may be provided with a stopper 330. The bottom of the water storage device 300 may be provided with a limit fitting (not shown). When the water storage device 300 is mounted on the heating base 210, the position-limiting matching part can be matched with the position-limiting part 230. The structures of the limiting part 230 and the limiting matching part may be arbitrary, for example, in the embodiment shown in the figures, the limiting part 230 is an annular protrusion, and the limiting matching part may be an annular groove adapted to the annular protrusion, and is adapted to the annular groove through the annular protrusion, so as to limit the water storage device 300. Therefore, the water storage device 300 can be installed on the heating base 210 in an overlapping manner, and is convenient to take down and place. In addition, when the water storage device 300 is placed, the positioning can be performed more accurately, so that the water storage device 300 is ensured to be in an accurate working position.

Preferably, a booster pump 130 may be further provided in the water purification main body. The booster pump 130 may employ various types of booster pumps known in the art or that may occur in the future. The cartridge assembly 140 may include a reverse osmosis cartridge. The water outlet of the booster pump 130 may be communicated to the water inlet of the reverse osmosis filter element. The water outlet of the filter element assembly 140 may be a pure water outlet of the reverse osmosis filter element. The booster pump 130 may pump raw water to the reverse osmosis filter element. The raw water is filtered by the reverse osmosis filter element to produce pure water and then produce waste water. The pure water may flow out into the water storage device 300 through the pure water outlet of the reverse osmosis filter element. The waste water can be directly discharged out of the desktop water purifier through a waste water outlet of the reverse osmosis filter element. The reverse osmosis filter element has higher filtering precision, and the water quality of the filtered purified water is better.

In embodiments where the water tank 100 is provided in the water purifying body, the water tank 100 may include a raw water tank 110 and a waste water tank 120. The raw water tank 110 may be used to store raw water to be filtered, such as tap water. The waste water tank 120 may be used to store waste water generated when the filter cartridge assembly 140 filters or washing water for washing the filter cartridge assembly 140. The water outlet of the raw water tank 110 may be communicated to the water inlet of the booster pump 130. The waste water outlet of the filter element assembly 140 may be communicated to the water inlet of the waste water tank 120. That is, the booster pump 130 may pump the raw water in the raw water tank 110 to the reverse osmosis filter. The wastewater may flow out through the wastewater outlet of the reverse osmosis cartridge into the wastewater tank 120. After a period of use, the user may dump the waste water stored in the waste water tank 120. In order to control the waste water, a waste water solenoid valve 153 may be further provided in the water purification main body. A wastewater solenoid valve 153 may be provided on the line between the wastewater outlet of the reverse osmosis cartridge and the water inlet of the wastewater tank 120. The waste water solenoid valve 153 may employ various types of solenoid valves known in the art or that may occur in the future.

The raw water tank 110 and the waste water tank 120 may be located at the same or different positions in the clean water body. Alternatively, the raw water tank 110 and the waste water tank 120 may be provided independently of each other. In the embodiment shown in the figures, a water stop 101 may be provided within the water tank 100. The water stop 101 includes, but is not limited to, a baffle. The water tank 100 is divided into two parts by a water stop 101 to form a raw water tank 110 and a waste water tank 120.

Preferably, as shown in fig. 2-6, the desktop water purifier may further include a liquid level detector and controller 500. The liquid level detector may employ various types of liquid level detectors known in the art or that may occur in the future, such as a float level sensor, a ball level sensor, a static pressure level sensor, and the like. The liquid level detector may be used to detect the liquid level within the water storage device 300. The controller 500 may be electrically connected to the liquid level detector. The controller 500 may control the operation of the booster pump 130 when the liquid level in the water storage device 300 is less than a liquid level threshold. Illustratively, the liquid level threshold may be a highest liquid level value of the water storage device 300. That is, once the level of pure water stored in the water storage means 300 is less than the maximum level, this indicates that the pure water in the water storage means 300 is not filled. At this time, the controller 500 may control the operation of the booster pump 130 so as to pump the raw water in the raw water tank 110 to the filter element assembly 140, thereby producing pure water to be stored in the water storage device 300. When the liquid level of the pure water stored in the water storage means 300 reaches the maximum liquid level, this indicates that the water storage means 300 is relatively full of pure water. At this time, the controller 500 may control the booster pump 130 to stop operating so that the filter cartridge assembly 140 stops producing pure water. The liquid level threshold value can be set by a person skilled in the art according to actual use requirements. In any event, the level threshold is typically pre-set when the desktop water purifier is manufactured or installed. Through the arrangement, pure water in the water storage device 300 can be ensured to be full at any time so as to meet the requirement of using by a user at any time. Moreover, the desktop water purifier is more intelligent and automatic, and the use experience of a user is better.

Alternatively, the controller 500 may be further configured to control the heating device 200 to heat the water storage device 300 when the booster pump 130 stops operating. In this way, the heating device 200 can automatically heat the pure water in the water storage device 300 to a set temperature for the user to use at any time. Further, the heating device 200 can be prevented from heating the water storage device 300 having no water, and the safety of the water storage device 300 can be ensured.

Of course, the heating device 200 may also heat the water storage device 300 while the filter element assembly 140 produces water. This may improve efficiency. However, in order to prevent dry burning without water, a detector, such as a weighing sensor, a lower limit liquid level meter, a temperature sensor, etc., may be provided on the water storage device 300 to ensure that the water storage device 300 is heated in the presence of water.

Optionally, in one set of embodiments, the liquid level detector may include a float and a proximity switch. The float may, for example, be disposed in a communicator in communication with the water storage device 300, and when the liquid level reaches a liquid level threshold, the float approaches a proximity switch, which sends an electrical signal to the controller 500. The controller 500 may control the booster pump 130 to stop operating according to the electric signal.

A preferred level detector is described below. As shown in fig. 2-6, the liquid level detector may include an infrared emitter 410 and an infrared receiver 420. Infrared emitter 410 and infrared receiver 420 may be positioned in facing relation such that infrared light emitted by infrared emitter 410 may be received by infrared receiver 420. The infrared transmitter 410 and the infrared receiver 420 may be respectively disposed on the water purifying body by any suitable means such as welding, bonding, etc. A light-transmitting window (not shown) may be provided on a sidewall of the water storage device 300. The light-transmitting window may expose a liquid level within the water storage device 300. Illustratively, the light-transmitting window may be made of a material having a relatively good light-transmitting property, such as glass. A light transmissive window may be located in the optical transmission path between infrared emitter 410 and infrared receiver 420. The optical transmission path refers to a path through which infrared light emitted from the infrared emitter 410 reaches the infrared receiver 420. The light transmissive window may be a one-piece window. The light-transmitting windows may also be two opposite windows, and the infrared light emitted from the infrared emitter 410 may enter the water storage device through one window and then exit the water storage device through the other window to reach the infrared receiver 420. The light-transmitting window may be arranged in other ways as long as it meets the above requirements.

When the level of pure water stored in the water storage device 300 is less than the level threshold, infrared light emitted from the infrared emitter 410 may be received by the infrared receiver 420 through the light-transmissive window. The infrared receiver 420 may send a first electrical signal to the controller 500. At this time, the controller 500 may control the operation of the booster pump 130. With the continuous injection of pure water, when the liquid level of pure water stored in the water storage device 300 reaches the liquid level threshold, the infrared light received by the infrared receiver 420 may be attenuated or even unable to receive infrared light due to the blockage of pure water in the water storage device 300, and the infrared receiver 420 may send a second electrical signal to the controller 500 or not send an electrical signal. One of the first electrical signal and the second electrical signal may be high level and the other may be low level. At this time, the controller 500 may control the booster pump 130 to stop operating. Optionally, the controller 500 may also control the heating device 200 to heat the water storage device 300 at this time. With this arrangement, the liquid level detector need not be disposed inside the water storage device 300, which is more convenient for electrical connection with the controller 500. Moreover, the liquid level detector does not contact with the pure water, thereby preventing the pure water from being secondarily polluted.

Further, a recess 180 may be provided on a sidewall of the water purifying body. The recess 180 may be recessed toward the inside of the water purifying body. The recess 180 may be opened toward the water storage device 300. The infrared transmitter 410 and the infrared receiver 420 may be respectively disposed on both sides of the recess 180 by any suitable means such as welding, bonding, and the like. Preferably, the infrared transmitter 410 and the infrared receiver 420 are disposed at both sides of the recess 180 by a screw connection. When the water storage device 300 is mounted on the heating device 200, the light-transmitting window may be received in the recess 180. Through the arrangement, infrared light emitted by the infrared emitter 410 can conveniently pass through the light-transmitting window to reach the infrared receiver 420, so that the desktop water purifier is simple in structure and low in production cost.
