Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water purification devices, in particular to a table type water purifying and drinking machine. BACKGROUND

[0002] The table type water purifying and drinking machine is a small household water purification device for filtering and purifying water, so that the water quality meets the safe and healthy drinking standard. With the increasing attention to the health of drinking water, the table type water purifying and drinking machine has gradually become a daily necessity in people's life.

[0003] A common multifunctional table type water purifying and drinking machine on the market has the functions of filtering water, storing water, instant heating and the like. The instant heating function is very popular among consumers. Such a product is provided with an instant heating body capable of rapidly heating. The instant heating body can rapidly heat and warm the water to boiling. However, a large amount of hot gas is generated in the heating process, and a part of the water is also vaporized at the time of boiling. When the hot water and the large amount of hot gas are discharged through the water outlet nozzle in the mixed state, the water flow is prone to be large or small, left and right floating, intermittent, and intermittent flow. In order to improve the above problems, the existing table type water purifying and drinking machine is generally provided with a water vapor separation water outlet nozzle, so that the hot water and the hot gas are separated in the water outlet nozzle, the hot water is discharged from the hot water outlet, and the hot gas is discharged from the exhaust port. However, this structure also has certain disadvantages, for example, an exhaust pipe needs to be additionally increased in the machine body to discharge the hot gas discharged from the exhaust port outside the machine body, which complicates the internal structure, brings pressure to the internal space of the machine body, is not conducive to miniaturization, and further, the hot gas discharged outside the machine body is prone to be sprayed to the personnel beside the machine body, causing safety problems. CONTENT OF THE UTILITY MODEL

[0012] The top wall of the water outlet nozzle is provided with a gas guide boss which is upwardly protruded, and the front exhaust port and the rear exhaust port are arranged in the gas guide boss.

[0013] The inside of the water outlet nozzle is provided with a bubble breaking part at a position which is opposite to the hot water inlet, so that the bubbles in the hot water entering the hot water inlet are broken by colliding with the bubble breaking part.

[0014] The hot water inlet is arranged on the bottom surface of the water outlet nozzle, and the bubble breaking part is configured as a protruding point which protrudes from the top wall of the water outlet nozzle towards the hot water inlet.

[0015] The water level detection unit comprises a float, a high water level recognition piece and a low water level recognition piece, the float is arranged in the communication pipe, the high water level recognition piece and the low water level recognition piece are arranged outside the communication pipe, the high water level recognition piece and the low water level recognition piece realize water level detection by recognizing the position of the float in the communication pipe, and the position of the float recognized by the high water level recognition piece is lower than the arrangement position of the air inlet.

[0016] The communication pipe is provided with a guide convex rib, which guides the float to move up and down in the communication pipe and stops and positions the float, so that an air gap is formed between the float and the inner wall of the communication pipe.

[0017] Thanks to the above technical solutions, the application has at least the following technical effects:

[0018] 1. The communication pipe and the pure water kettle form a communication vessel structure, which can be matched with the water level detection unit to detect the water level in the pure water kettle. The water outlet nozzle is provided with a hot water outlet and an exhaust port. After the hot water and hot gas are separated in the water outlet nozzle, the hot water is discharged through the hot water outlet, and most of the hot gas is discharged through the exhaust port. The exhaust port is communicated with the air inlet of the communication pipe, so that the hot gas discharged from the exhaust port can be discharged into the communication pipe and quickly become condensed water after being cooled in the communication pipe, effectively reducing the heat conduction of the hot gas to the machine body, thereby helping to reduce the temperature rise of the whole machine. Moreover, only a simple pipeline is needed to connect the exhaust port and the air inlet, which has the advantages of few accessories, simple structure and easy assembly. The hot gas does not need to be discharged outside the table type water purifier, avoiding being sprayed to the personnel beside the machine body, which helps to improve the use safety. In addition, by arranging the air inlet at the top of the communication pipe, the water in the communication pipe is prevented from entering the air inlet and flowing towards the water outlet nozzle. Furthermore, the pure water kettle is connected to the instant heating body through the water pump, and the water in the pure water kettle serves as the water source for supplying water to the instant heating body. When the pure water kettle supplies water to the instant heating body, the water level in the communication pipe decreases synchronously with the water level in the pure water kettle, causing a negative pressure phenomenon in the communication pipe, which in turn has a siphon effect on the hot gas in the water outlet nozzle through the air inlet, so that the hot gas quickly flows from the water outlet nozzle to the communication pipe, further improving the water vapor separation efficiency in the water outlet nozzle.

[0019] 2. As a preferred form of the application, the exhaust port includes a front exhaust port and a rear exhaust port, so that the hot gas flow area is effectively increased, the hot gas is discharged more smoothly, and a large amount of hot gas generated by the hot water can be transported to the communication pipe for condensation, which helps to quickly separate the water vapor in the water outlet nozzle. The front exhaust port and the rear exhaust port are arranged along the fluid path from the hot water inlet to the hot water outlet. The front exhaust port can first guide the hot gas generated by the hot water just entering the water outlet nozzle into the communication pipe, and the rear exhaust port can continue to guide the hot gas not discharged through the front exhaust port into the communication pipe, thereby rapidly reducing the air pressure in the water outlet nozzle and making the water outlet nozzle discharge water smoothly.

[0020] Further, the gas passage is composed of a converging passage and two branch passages, and has a Y-shaped structure. The front exhaust port and the rear exhaust port respectively transport hot gas outward through the two branch passages. The hot gas of the two branch passages converges in the converging passage and then enters the communication pipe, so that the gas passage structure is simple, and only one air inlet needs to be arranged on the communication pipe to communicate with the converging passage, which helps to reduce the number of openings of the communication pipe and reduce the sealing cost.

[0021] 3. As a preferred mode of the present application, the top wall of the water outlet nozzle is provided with an upwardly protruding air guide boss, and the front and rear air outlets are arranged on the air guide boss. The hot air itself has a tendency to flow upward, so that the air guide boss can gather and guide the hot air generated in the water outlet nozzle, so that the hot air enters the front and rear air outlets as much as possible and as quickly as possible, thereby helping the water vapor to separate quickly and optimizing the water outlet shape. In addition, after the air guide boss is upwardly protruded, the front and rear air outlets are away from the water flow on the bottom wall of the water outlet nozzle, thereby reducing the risk of water flow in the water outlet nozzle entering the front and rear air outlets.

[0022] 4. As a preferred mode of the present application, the inside of the water outlet nozzle is provided with a bubble breaking part at a position opposite to the hot water inlet, so that the bubbles in the hot water just entering the hot water inlet are broken by colliding with the bubble breaking part, so as to disperse the bubbles and facilitate the air outlet to better exhaust air.

[0023] 5. As a preferred mode of the present application, the position of the float recognized by the high water level recognition member is lower than the setting position of the air inlet, so that the high water level in the communication pipe and the highest position of the float in the communication pipe are both lower than the air inlet, thereby preventing the water in the communication pipe from entering the air inlet and preventing the Fu character from blocking the air inlet.

[0047] In the embodiments of the present application, a desktop water purifier is provided. For the convenience of description and understanding, the following content provided by the present application is described on the basis of the structure of the product. Of course, those skilled in the art can understand that the above structure is only a specific example and illustrative description, and cannot constitute a specific limitation on the technical solutions provided by the present application.

[0048] As shown in Figures 1 to 8 A desktop water purifier provided by the present application includes a filter element 1, a pure water kettle 2, a heating element 3, a water level detection device and a water outlet nozzle 4. The pure water outlet of the filter element 1 is communicated with the pure water kettle 2. The pure water kettle 2 is communicated with the heating element 3 through a water pump 5. The water outlet nozzle 4 is provided with a hot water inlet 41, a hot water outlet 42 and an exhaust port 43. The water outlet of the heating element 3 is communicated with the hot water inlet 41. The water level detection device includes a communication pipe 6 and a water level detection unit arranged on the communication pipe 6. The communication pipe 6 and the pure water kettle 2 form a communication vessel structure. The communication pipe 6 is provided with an air inlet 61. The air inlet 61 is arranged at the top of the communication pipe 6. The exhaust port 43 is communicated with the air inlet 61.

[0049] Specifically, the filter element 1 is used to filter raw water into pure water, the pure water outlet of the filter element 1 is communicated with the pure water kettle 2, so that the pure water kettle 2 can store the pure water produced by the filter element 1, and the pure water kettle 2 can also supply water to the instant heater 3 through the water pump 5, so that the normal temperature water is heated to boiling through the instant heater 3 in a very short time, and the hot water formed in the instant heater 3 is delivered to the water outlet nozzle 4 through the hot water inlet 41, and then discharged through the hot water outlet 42. The water level detection device detects the water level in the pure water kettle 2, so that when the water level in the pure water kettle 2 is too low, the filter element 1 can timely supplement water to the pure water kettle 2, or when the water level in the pure water kettle 2 is too high during the process of the filter element 1 supplementing water to the pure water kettle 2, the filter element 1 stops supplementing water.

[0050] The communication pipe 6 and the pure water kettle 2 form a communication structure, so as to realize the water level detection in the pure water kettle 2 in cooperation with the water level detection unit. The water outlet nozzle 4 is provided with the hot water outlet 42 and the exhaust port 43, after the hot water and the hot gas are separated in the water outlet nozzle 4, the hot water is discharged through the hot water outlet 42, and the hot gas is discharged through the exhaust port 43, and the exhaust port 43 is communicated with the air inlet 61 of the communication pipe 6, so that the hot gas discharged from the exhaust port 43 can be discharged into the communication pipe 6, and quickly changes into condensed water after meeting the cold in the communication pipe 6, effectively reducing the heat conduction of the hot gas to the machine body, thereby helping to reduce the temperature rise of the whole machine; moreover, only a simple pipeline is needed to connect the exhaust port 43 and the air inlet 61, which is simple in structure and convenient to assemble; the hot gas does not need to be discharged outside the desktop water purifier, avoiding being sprayed to the personnel beside the machine body, which helps to improve the use safety; in addition, by arranging the air inlet 61 at the top of the communication pipe 6, the water in the communication pipe 6 is prevented from entering the air inlet 61 and flowing towards the water outlet nozzle 4. Furthermore, the pure water kettle 2 is communicated with the instant heater 3 through the water pump 5, and the water in the pure water kettle 2 serves as the water source for supplying water to the instant heater 3, so that when the pure water kettle 2 supplies water to the instant heater 3, the water level in the communication pipe 6 decreases synchronously with the water level in the pure water kettle 2, so that the negative pressure phenomenon occurs in the communication pipe 6, and then the hot gas in the water outlet nozzle 4 has a siphon effect through the air inlet 61, so that the hot gas quickly flows from the water outlet nozzle 4 to the communication pipe 6, further improving the water vapor separation efficiency in the water outlet nozzle 4.

[0051] As a preferred embodiment of the present application, as shown in Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the exhaust port 43 includes a front exhaust port 431 and a rear exhaust port 432, which are arranged along the fluid path from the hot water inlet 41 to the hot water outlet 42. The existing middle-type water purifying machine has only one exhaust port in the water outlet nozzle, and the exhaust speed is low. A large amount of hot gas gathered in the water outlet nozzle can easily cause pressure build-up, which in turn affects the water type of the water outlet. Therefore, in the present scheme, the exhaust port 43 includes a front exhaust port 431 and a rear exhaust port 432, so that the hot gas flow area is effectively increased, the hot gas is discharged more smoothly, and a large amount of hot gas generated by the hot water output can be transported to the communication pipe 6 to realize condensation, which helps the water vapor in the water outlet nozzle 4 to be quickly separated; the front exhaust port 431 and the rear exhaust port 432 are arranged along the fluid path from the hot water inlet 41 to the hot water outlet 42. The front exhaust port 431 can first guide the hot gas generated by the hot water just entering the water outlet nozzle 4 into the communication pipe 6, and the rear exhaust port 432 continues to guide the hot gas that has not been discharged through the front exhaust port 431 and the newly generated hot gas of the backward flowing hot water into the communication pipe 6, thereby rapidly reducing the internal pressure of the water outlet nozzle 4 and smoothly discharging water from the water outlet nozzle 4.

[0052] As a preferred embodiment of the present embodiment, the exhaust port 43 is communicated with the gas inlet 61 through a gas passage, and the gas passage includes a confluence passage, one end of the confluence passage is communicated with two branch passages, the other end is communicated with the gas inlet 61, and the two branch passages are respectively communicated with the front exhaust port 431 and the rear exhaust port 432. Those skilled in the art can understand that the gas passage is composed of the confluence passage and the two branch passages, and the whole is in Y-shaped structure. The front exhaust port 431 and the rear exhaust port 432 respectively transport hot gas outward through the two branch passages. The hot gas of the two branch passages enters the communication pipe 6 after confluence in the confluence passage, so that the gas passage structure is simple, and only one gas inlet 61 needs to be arranged in the communication pipe 6 to communicate with the confluence passage, which helps to reduce the number of openings of the communication pipe 6 and reduce the sealing cost.

[0053] Regarding the formation mode of the gas passage, in a preferred example, as shown in FIG. 6, the exhaust port 43 is communicated with the gas inlet 61 through a gas passage, and the gas passage includes a confluence passage and two branch passages. One end of the confluence passage is communicated with the two branch passages, and the other end is communicated with the gas inlet 61. The two branch passages are respectively communicated with the front exhaust port 431 and the rear exhaust port 432. Figures 3 to 6As shown, the table type purifying and drinking machine comprises a first air pipe 71, a second air pipe 72, a third air pipe 73 and a connecting piece 74, two branch flow channels are formed in the first air pipe 71 and the second air pipe 72 respectively, a converging flow channel is formed in the third air pipe 73, the connecting piece 74 is hollow inside and is provided with a first interface, a second interface and a third interface, one end of the first air pipe 71 is connected with the front air outlet 431, the other end of the first air pipe 71 is connected with the first interface, one end of the second air pipe 72 is connected with the rear air outlet 432, the other end of the second air pipe 72 is connected with the second interface, one end of the third air pipe 73 is connected with the third interface, and the other end of the third air pipe 73 is connected with the communicating pipe 6. The connecting piece 74 is a transition piece for connecting the first air pipe 71 and the second air pipe 72 with the third air pipe 73, and hot air enters the connecting piece 74 from the first air pipe 71 and the second air pipe 72 and then enters the third air pipe 73. Preferably, the first air pipe 71, the second air pipe 72 and the third air pipe 73 can all be selected as flexible silica gel hoses, and the connecting piece 74 can be selected as a hard structure, on the one hand, the first air pipe 71, the second air pipe 72 and the third air pipe 73 can be reliably inserted with the connecting piece 74, and the first air pipe 71 and the second air pipe 72 can be connected with the water outlet nozzle 4 and the third air pipe 73 can be connected with the communicating pipe 6, on the other hand, the first air pipe 71, the second air pipe 72 and the third air pipe 73 can be supported and shaped by the connecting piece 74, so as to effectively prevent the three hoses from being seriously bent and deformed downward under the action of the gravity of water and the gravity of the hoses themselves and hindering the flow of hot air. Of course, as an alternative embodiment, a Y-shaped pipe formed integrally can be used to connect the front air outlet 431 and the rear air outlet 432 with the communicating pipe 6, and the Y-shaped pipe can also be a silica gel hose.

[0054] As another alternative embodiment of the present embodiment, although the drawings are not shown, the table type purifying and drinking machine can also comprise a first air pipe and a second air pipe, one end of the first air pipe is connected with the front air outlet, the other end of the first air pipe is connected with the communicating pipe, one end of the second air pipe is connected with the rear air outlet, and the other end of the second air pipe is connected with the communicating pipe. Different from the scheme that the gas flow channel is in a Y-shaped structure as a whole, in the present embodiment, one first air pipe is used to connect the front air outlet and the communicating pipe, and another second air pipe is used to connect the rear air outlet and the communicating pipe, therefore, two air inlets need to be formed on the communicating pipe, and the two air inlets are connected with the first air pipe and the second air pipe respectively.

[0055] In the preferred embodiment, as shown in Figure 4 and Figure 6As shown, the top wall of the water outlet nozzle 4 is provided with a gas guiding boss 44 upwardly protruding, and the front and rear gas outlets 431 and 432 are arranged on the gas guiding boss 44. Those skilled in the art can understand that, by arranging the front and rear gas outlets 431 and 432 on the gas guiding boss 44, the gas guiding boss 44 can utilize the upward flowing tendency of the hot gas itself to gather and guide the hot gas generated in the water outlet nozzle 4, so that the hot gas can enter the front and rear gas outlets 431 and 432 as much as possible and as quickly as possible, thereby helping the water vapor to separate quickly and optimizing the water outlet shape; in addition, after the gas guiding boss 44 is upwardly protruding, the front and rear gas outlets 431 and 432 can be away from the water flow on the bottom wall of the water outlet nozzle 4, thereby reducing the risk of water flow in the water outlet nozzle 4 entering the front and rear gas outlets 431 and 432.

[0056] As a preferred embodiment of the present application, the inside of the water outlet nozzle 4 is provided with a bubble breaking part at a position opposite to the hot water inlet 41, so that the bubbles in the hot water entering the hot water inlet 41 can be broken by colliding with the bubble breaking part. Those skilled in the art can understand that, when the hot water just enters the water outlet nozzle 4, it usually has relatively many bubbles, which can hinder the flow of the hot gas to the gas outlet 43. Therefore, by providing the inside of the water outlet nozzle 4 with a bubble breaking part at a position opposite to the hot water inlet 41, the bubbles in the hot water just entering the hot water inlet 41 can be broken by colliding with the bubble breaking part, thereby breaking the bubbles in time and quickly. This reduces the hindrance and facilitates the smooth flow of the hot gas towards the gas outlet 43 for better gas exhaust.

[0057] Regarding the structure of the bubble breaking part, in a preferred embodiment, as shown in Figure 6 The hot water inlet 41 is arranged on the bottom surface of the water outlet nozzle 4, and the bubble breaking part is configured as a protruding point 45 protruding from the top wall of the water outlet nozzle 4 towards the hot water inlet 41, for example, a circular protruding point, a sharp protruding point, etc., which has a simple structure and good bubble breaking effect. In other embodiments, the bubble breaking part can also be selected from other suitable structures, such as a sawtooth structure, a grid structure, etc.

[0058] As a preferred embodiment of the present application, as shown in Figure 7 and Figure 8As shown, the water level detecting unit comprises a float 81, a high water level identifying member 82 and a low water level identifying member 83. The float 81 is arranged in the communicating pipe 6, and the high water level identifying member 82 and the low water level identifying member 83 are arranged outside the communicating pipe 6. The high water level identifying member 82 and the low water level identifying member 83 detect the water level by identifying the position of the float 81 in the communicating pipe 6. The position of the float 81 identified by the high water level identifying member 82 is lower than the arranged position of the air inlet 61. Specifically, the high water level identifying member 82 and the low water level identifying member 83 can be a circuit board in which a dry reed and a resistor are combined together. When the dry reed is turned on by the magnetic float 81, the water level detection is realized. When the water pump 5 is working in the water pumping state, the water in the pure water kettle 2 is continuously supplied into the instant heater 3, and the water level continuously decreases. In order to avoid the water in the pure water kettle 2 being pumped out, the water pump 5 is controlled to be powered off when the position of the float 81 is identified by the low water level identifying member 83. The water pump 5 stops pumping water, and the pure water kettle 2 stops supplying water, so that the water level in the pure water kettle 2 is cut off at the low water level. When the filter element 1 supplies water to the pure water kettle 2, the filter element 1 is controlled to stop supplying water to the pure water kettle 2 when the position of the float 81 is identified by the high water level identifying member 82, so that the water level in the pure water kettle 2 is cut off at the high water level. The position of the float 81 identified by the high water level identifying member 82 is lower than the arranged position of the air inlet 61, so that the high water level in the communicating pipe 6 and the highest position of the float 81 in the communicating pipe 6 are both lower than the air inlet 61, thereby preventing the water in the communicating pipe 6 from entering the air inlet 61 and preventing the float 81 from blocking the air inlet 61.

[0059] Further, as shown in the drawings, Figure 8 The communicating pipe 6 is provided with a guide protrusion 62. The guide protrusion 62 guides the float 81 to move up and down in the communicating pipe 6, and stops and limits the float 81, so that an air gap is formed between the float 81 and the inner wall of the communicating pipe 6. Those skilled in the art can understand that, by arranging the guide protrusion 62, on the one hand, the up and down floating of the float 81 with the change of the water level in the communicating pipe 6 can be guided, and on the other hand, by stopping and limiting the float 81, the air gap is formed between the float 81 and the inner wall of the communicating pipe 6, so that the hot air can flow through the air gap towards the water flow below the float 81, and then quickly condense by colliding with the normal temperature water. Also, the water condensed by the hot air on the inner wall of the communicating pipe 6 can flow downwards along the inner wall, and not gather on the top of the float 81, so as to avoid the float 81 being pressed downwards by the gravity of the water and affecting the detection accuracy.

[0061] Each embodiment in the present specification is described in a progressive manner, and the same or similar parts between each embodiment can be referred to each other. Each embodiment mainly describes the difference from other embodiments.
