Description

Technical Field

[0001] This application relates to the technical field of drinking water equipment, and in particular, to a direct drinking machine. Background Art

[0002] With the development of society, people's requirements for the quality of life are getting higher and higher. As an essential part of life, the quality of drinking water directly affects people's health. As a household device that can filter municipal tap water, a direct drinking machine uses a filter element to filter rust, sand, bacteria, viruses, heavy metal ions, and adsorbed residual chlorine in the municipal tap water, so that the water can meet the standard for direct drinking. The filtered water flows out through the water intake pipe connected to the direct drinking machine, facilitating people to obtain it.

[0003] However, scale is likely to form in the water intake pipe of the current direct drinking machine after long-term use and is not easy to clean. In addition, the pipe orifice of the water intake pipe is exposed to the air. When not in use for a long time, dust or other pollutants in the air easily enter from the pipe orifice and accumulate on the inner wall of the water intake pipe, thereby affecting the water quality. Summary of the Invention

[0004] In order to improve the influence of the dirt in the water intake pipe of the direct drinking machine on the water quality, this application provides a direct drinking machine.

[0005] The direct drinking machine provided by this application adopts the following technical solutions: A direct drinking machine includes a water purification system, a cleaning system, and a water intake pipe; The water purification system is communicated with the water intake pipe, and the water purification system is used for purifying municipal tap water; The cleaning system includes a housing, a first driving member is connected inside the housing, an output end of the first driving member is connected to a second driving member, and the first driving member is used for driving the second driving member to move up and down; an output end of the second driving member is connected with a cleaning member through a connecting rod, and the second driving member is used for driving the cleaning member to rotate so that the cleaning member cleans the water intake pipe.

[0006] By adopting the above technical solutions, the first driving member drives the second driving member to move up and down, and the second driving member drives the cleaning member to rotate, thereby realizing the cleaning of the inner wall of the water intake pipe by the cleaning member and reducing the possibility that dirt accumulates on the inner wall of the water intake pipe and affects the water quality.

[0007] Optionally, an activity port is arranged inside the housing, and the connecting rod passes through the activity port; a blocking block is connected to the connecting rod, and the blocking block is used for blocking the activity port when the cleaning member cleans the water intake pipe.

[0008] By adopting the above technical solution, the blocking block blocks the movable opening when the cleaning member cleans the water intake pipe, thereby reducing the possibility of water flowing into the shell and reducing the working performance of the first driving member and the second driving member.

[0009] Optionally, the cleaning member further includes a brush connected to the connecting rod, and when the brush is located in the water intake pipe, it abuts against the water intake pipe.

[0010] By adopting the above technical solution, the brush rotates synchronously with the connecting rod under the drive of the second driving member, thereby comprehensively cleaning the inner wall of the water intake pipe and removing dirt attached to the inner wall of the water intake pipe.

[0011] Optionally, the brush is spirally arranged on the connecting rod.

[0012] By adopting the above technical solution, the spiral arrangement of the brush on the connecting rod can effectively increase the cleaning area. At the same time, when the brush rotates with the connecting rod, the spiral arrangement enables the dirt to be transported out of the water intake pipe as the brush rotates, further improving the cleaning effect of the inner wall of the water intake pipe.

[0013] Optionally, the cleaning member includes a support block, the support block is connected to the connecting rod, an air bag is connected inside the support block, and the air bag abuts against the inner wall of the water intake pipe after being inflated to clean the water intake pipe.

[0014] By adopting the above technical solution, after the brush has finished cleaning, the airbag is inflated and abutted against the inner wall of the water intake pipe, and the inner wall of the water intake pipe is scraped from top to bottom under the control of the first driving member, so that the dirt that the brush has not cleaned up is pushed out of the water intake pipe, further improving the cleaning effect of the cleaning member. After the inner wall of the water intake pipe is cleaned, the airbag remains inflated to block the movable port, reducing the possibility of water entering the shell when the filtered water passes through the water intake pipe. At the same time, when the direct drinking machine is not used for a long time, the airbag remains inflated to block the mouth of the water intake pipe, reducing the possibility of dust or gaseous pollutants in the air entering the water intake pipe, and further reducing the impact of dirt accumulation on the inner wall on the water quality.

[0015] Optionally, the cleaning system further comprises a blower disposed in the housing, the blower being used to control the inflation or exhaust of the airbag; A connecting seat is rotatably connected to the connecting rod. A first ventilation cavity is arranged in the connecting seat, and the air blower is communicated with the first ventilation cavity through an air duct; a second ventilation cavity is arranged in the connecting rod, and the first ventilation cavity is communicated with the second ventilation cavity; a third ventilation cavity is arranged in the support block, the second ventilation cavity is communicated with the third ventilation cavity, and the third ventilation cavity is also communicated with the airbag.

[0016] By adopting the above technical solution, the air blower uses the communicated first ventilation cavity, second ventilation cavity and third ventilation cavity to convey gas to or discharge gas from the airbag, so that the airbag expands or contracts.

[0017] Optionally, the connecting seat includes a first connecting block, and the first ventilation cavity is located in the first connecting block; second connecting blocks are connected to both sides of the first connecting block, and the second connecting blocks are rotatably connected to the connecting rod.

[0018] By adopting the above technical solution, the second connecting blocks are arranged on both sides of the first connecting block and are rotatably connected to the connecting rod, so that after the first connecting block is communicated with the air duct, it does not rotate together with the connecting rod, improving the connection stability between the air duct and the first ventilation cavity.

[0019] Optionally, a storage groove is arranged on the periphery of the support block, and the storage groove is used for storing the airbag.

[0020] By adopting the above technical solution, the contracted airbag can be accommodated in the storage groove, providing a space for discharging the dirt brushed by the brush.

[0021] Optionally, a discharge block is connected to one side of the support block close to the second driving member, and an inclined surface is arranged on the discharge block.

[0022] By adopting the above technical solution, the discharge block reduces the possibility that the dirt accumulates on the discharge block and cannot be discharged from the water intake pipe after the dirt falls off through the inclined surface.

[0023] Optionally, a slide rail is arranged in the housing, a slider is connected to the second driving member, and the slider is slidably connected to the slide rail.

[0024] By adopting the above technical solution, the cooperation between the slide rail and the slider makes the second driving member more stable during the lifting process, reducing the possibility that the cleaning member works unstably due to vibration or deviation, thereby improving the reliability of the cleaning system.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The first driving member drives the second driving member to move up and down, and the second driving member drives the cleaning member to rotate, realizing the cleaning of the inner wall of the water intake pipe by the cleaning member, reducing the possibility of dirt accumulation on the inner wall of the water intake pipe and affecting the water quality.

[0026] 2. By providing an airbag, after the brush cleaning is completed, the airbag is inflated and abuts against the inner wall of the water intake pipe, and under the control of the first driving member, it scrapes the inner wall of the water intake pipe from top to bottom, pushing out the dirt that the brush has not cleaned cleanly from the water intake pipe, further improving the cleaning effect of the cleaning member. After the inner wall of the water intake pipe is cleaned, the airbag remains inflated and can block the movable opening, reducing the possibility of water flow entering the housing when the direct drinking machine conveys drinking water. At the same time, when the direct drinking machine is not used for a long time, the airbag remains inflated and can block the pipe orifice of the water intake pipe, reducing the possibility of dust or gas pollutants in the air entering the water intake pipe, and further reducing the impact of dirt on the water quality.

[0027] 3. The airbag can be accommodated in the storage groove by shrinking, providing a space for the dirt brushed out by the brush to be discharged. Description of the Drawings

Detailed Embodiments

[0030] The following will further elaborate on this application in conjunction with the attached Figure 1 - attached Figure 7 drawings to provide a more detailed description of this application.

[0031] An embodiment of this application discloses a direct drinking machine. As Figure 1 shown in Figure 2 , the direct drinking machine includes a water purification system 1, a cleaning system 2, and a water intake pipe 3. The water purification system 1 includes filter elements 101. In this embodiment, a total of two filter elements 101 are provided. The filter element 101 is connected with a water inlet pipe and a water outlet pipe 102. The water inlet pipe is used for municipal tap water to enter the direct drinking machine. Inside the filter element 101, there are PP cotton, activated carbon rods, RO reverse osmosis membranes, etc., which can effectively remove harmful substances such as rust, sand, bacteria, heavy metal ions, and residual chlorine in municipal tap water, making the outflowing water meet the direct drinking standard, thereby improving the water quality safety and user experience. The water intake pipe 3 is communicated with the water outlet pipe 102, and the drinking water filtered by the filter element 101 enters the water intake pipe 3 through the water outlet pipe 102, facilitating people to draw water and drink at the water intake pipe 3.

[0032] As Figure 2 shown in Figure 3 , the cleaning system 2 is located above the water intake pipe 3. The cleaning system 2 includes a housing 201, and the housing 201 is fixedly connected to the outer shell of the water purification system. A first driving member 202 is fixedly connected inside the housing 201. Preferably, the first driving member 202 is an electric push rod. The output end of the first driving member 202 is fixedly connected to a second driving member 203. Preferably, the second driving member 203 is a motor. The output end of the second driving member 203 is fixedly connected to a connecting rod 204, and a cleaning member 205 is connected to the connecting rod 204. The cleaning member 205 includes a support block 2051 fixedly connected to the connecting rod 204. The lifting of the support block 2051 inside the water intake pipe 3 can be realized through the first driving member 202, and the rotation of the support block 2051 can be realized through the second driving member 203. In addition, a slide rail is fixedly connected inside the housing 201, and a slider is fixedly connected to the body of the second driving member 203. The cooperation between the slide rail and the slider makes the second driving member 203 more stable during the lifting process, reducing the possibility of unstable operation of the cleaning member 205 caused by vibration or deviation, thereby improving the reliability of the cleaning system 2. Among them, both the first driving member 202 and the second driving member 203 are electrically connected to the controller, and the controller can control the water output of the water purification system 1.

[0033] As Figure 4 shown in Figure 5As shown, the cleaning system 2 further includes a blower 206 fixedly connected inside the housing 201. A connecting seat 207 is rotatably connected to the connecting rod 204. Among them, the connecting seat 207 includes a first connecting block 2071 and a second connecting block 2072. A second connecting block 2072 is fixedly connected to both the upper and lower sides of the first connecting block 2071, and the second connecting block 2072 is connected to the connecting rod 204 through a sealed bearing. A first ventilation cavity 4 is provided inside the first connecting block 2071, and the blower 206 is communicated with the first ventilation cavity 4 through an air duct 2061, so that when the connecting rod 204 rotates, the first connecting block 2071 does not rotate with the connecting rod 204, improving the stability of the connection between the air duct 2061 and the first ventilation cavity 4. Among them, a solenoid valve is connected to the air duct 2061, and both the blower 206 and the solenoid valve are electrically connected to the controller. Through the cooperation of the blower 206 and the solenoid valve, the airbag 2053 can maintain an inflated or deflated state.

[0034] As Figure 5 and Figure 6 shown, a second ventilation cavity 5 is provided inside the connecting rod 204, and the second ventilation cavity 5 is communicated with the first ventilation cavity 4.

[0035] As Figure 6 and Figure 7 shown, a plurality of third ventilation cavities 6 are provided on the support block 2051. In this embodiment, 8 third ventilation cavities 6 are provided, and the third ventilation cavities 6 are communicated with the second ventilation cavity 5. An airbag 2053 is connected to the support block 2051, and the airbag 2053 is communicated with the third ventilation cavity 6. Through the cooperation of the first ventilation cavity 4, the second ventilation cavity 5 and the third ventilation cavity 6, the blower 206 can inflate or deflate the airbag 2053, so that the airbag 2053 expands or contracts.

[0036] As Figure 4 shown, the cleaning member 205 further includes a brush 2052 fixedly connected to the connecting rod 204, and the brush 2052 is spirally arranged. Under the control of the second driving member 203, the brush 2052 rotates with the rotation of the connecting rod 204, thereby cleaning the inner wall of the water intake pipe 3. When the brush 2052 rotates with the connecting rod 204, the spiral arrangement enables the dirt to be conveyed out of the water intake pipe 3 as the brush 2052 rotates, further improving the cleaning effect of the inner wall of the water intake pipe 3.

[0037] When the brush 2052 cleans the inner wall of the water intake pipe 3, the blower 206 sucks air to contract the airbag 2053, thereby leaving an evacuation space for the dirt brushed off by the brush 2052. After the brush 2052 finishes cleaning, the blower 206 inflates the airbag 2053. Under the control of the first driving member 202, the airbag 2053 scrapes the inner wall of the water intake pipe 3 from top to bottom, pushing out the dirt that the brush has not cleaned cleanly, further improving the cleaning effect.

[0038] Meanwhile, as Figure 4 and Figure 6 shown, a discharge block 2054 is fixedly connected to one side of the support block 2051 close to the brush 2052. The discharge block 2054 is provided with an inclined surface, and the inclined surface reduces the possibility that the dirt accumulates on the discharge block 2054 and cannot be discharged from the water intake pipe 3 after falling off.

[0039] In addition, as Figure 6 shown, a storage groove 7 is provided on the peripheral side of the support block 2051. After the airbag 2053 shrinks, it can be accommodated in the storage groove 7, providing a discharge space for the discharge of dirt when the brush 2052 rotates for cleaning.

[0040] As Figure 4 shown, a movable opening 2011 is further provided at the bottom of the housing 201. The connecting rod 204 passes through the movable opening 2011, and a blocking block 208 is fixedly connected to the connecting rod 204. When the first driving member 202 moves the brush 2052 into the water intake pipe 3, the blocking block 208 reaches the position of the movable opening 2011 and blocks the movable opening 2011. When the brush 2052 works, the controller controls the water purification system 1 to discharge water flow for cleaning dirt, blocking the movable opening 2011, reducing the possibility that the water flow enters the housing 201 and affects the working performance of the first driving member 202 and the second driving member 203. In addition, after the inner wall of the water intake pipe 3 is cleaned, the airbag 2053 is kept inflated, and under the control of the second driving member 203, the airbag 2053 is moved to the movable opening 2011 to block the movable opening 2011, reducing the possibility that the water flow enters the housing 201 when taking water for drinking.

[0041] The implementation principle of a direct drinking machine according to an embodiment of the present application is as follows: When the inner wall of the water intake pipe 3 needs to be cleaned, the controller drives the first driving member 202, the second driving member 203, the blower 206 and the solenoid valve to work. The blower 206 and the solenoid valve cooperate to make the airbag 2053 shrink into the storage groove 7. Under the cooperation of the first driving member 202 and the second driving member 203, the brush 2052 cleans the inner wall of the water intake pipe 3. Meanwhile, during the cleaning process of the brush 2052, the controller controls the water purification system 1 to intermittently supply water, and uses the water flow to cooperate with the cleaning of the brush 2052 to improve the cleaning effect of the inner wall of the water intake pipe 3.

[0042] After the brush 2052 has been cleaning for a period of time, the second driving member 203 stops working. At this time, under the action of the first driving member 202, the airbag 2053 moves upward by a certain distance, and then the blower 206 and the solenoid valve cooperate to keep the airbag 2053 inflated. Under the control of the first driving member 202, the airbag 2053 scrapes the inner wall of the water intake pipe 3 from top to bottom, pushing out the dirt that the brush 2052 has not cleaned, further improving the cleaning effect.

[0043] After the airbag 2053 has completed cleaning, the first driving member 202 controls the support block 2051 to move to the movable port 2011, so that the inflated airbag 2053 blocks the movable port 2011, reducing the possibility of water flow entering the housing 201 during water intake. At the same time, when the direct drinking machine is not used for a long time, the controller keeps the airbag 2053 inflated and moves it to the pipe orifice of the water intake pipe 3, so that the airbag 2053 blocks the pipe orifice of the water intake pipe 3, reducing the possibility of dust or gas pollutants in the air entering the water intake pipe 3, and further reducing the impact of dirt on the water quality.

[0044] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. The same components are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
