Description

Technical Field

[0001] The present 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 demands for a higher quality of life are becoming increasingly stringent. As an essential part of life, the quality of drinking water directly impacts people's health. A direct drinking fountain is a household device that filters municipal tap water. It uses a filter element to remove rust, sand, bacteria, viruses, heavy metal ions, and residual chlorine from the water, making it safe for direct drinking. The filtered water flows out through a pipe connected to the direct drinking fountain, making it convenient for people to use.

[0003] However, the water pipe of the current direct drinking machine is prone to scale after long-term use and is difficult to clean. In addition, the nozzle of the water pipe is exposed to the air. When it is not used for a long time, dust or other pollutants in the air can easily enter through the nozzle and accumulate on the inner wall of the water pipe, thereby affecting the water quality. Summary of the Invention

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

[0005] The direct drinking machine provided in this application adopts the following technical solution:

[0006] A direct drinking machine, comprising a water purification system, a cleaning system and a water intake pipe;

[0007] The water purification system is connected to the water intake pipe, and the water purification system is used to purify municipal tap water;

[0008] The cleaning system includes a shell, a first driving member is connected to the shell, the output end of the first driving member is connected to the second driving member, the first driving member is used to drive the second driving member to rise and fall; the output end of the second driving member is connected to the cleaning member through a connecting rod, the second driving member is used to drive the cleaning member to rotate so that the cleaning member cleans the water intake pipe.

[0009] By adopting the above technical solution, 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, reducing the possibility of dirt accumulation on the inner wall of the water intake pipe and affecting the water quality.

[0010] Optionally, a movable opening is provided in the shell, and the connecting rod passes through the movable opening; a blocking block is connected to the connecting rod, and the blocking block is used to block the movable opening when the cleaning member cleans the water intake pipe.

[0011] By adopting the above technical solution, the blocking block blocks the movable opening when the cleaning member cleans the water intake pipe, reducing the possibility of water flowing into the shell and reducing the working performance of the first driving member and the second driving member.

[0012] 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.

[0013] 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.

[0014] Optionally, the brush is spirally arranged on the connecting rod.

[0015] 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.

[0016] Optionally, the cleaning member includes a support block connected to the connecting rod, an airbag connected to the support block, and the airbag abuts against the inner wall of the water intake pipe after being inflated to clean the water intake pipe.

[0017] By adopting the above-mentioned technical solution, after the brush has finished cleaning, the airbag is inflated and abutted against the inner wall of the water intake pipe, and under the control of the first driving member, the inner wall of the water intake pipe is scraped from top to bottom, and the dirt that the brush has not cleaned is pushed out of the water intake pipe, further improving the cleaning effect of the cleaning member. After the cleaning of the inner wall of the water intake pipe is completed, the airbag remains in an inflated state to block the movable port, reducing the possibility of water flow 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 in an inflated state to block the pipe 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 water quality after the inner wall.

[0018] 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;

[0019] A connecting seat is rotatably connected to the connecting rod, a first ventilation chamber is provided in the connecting seat, and the blower is connected to the first ventilation chamber through an air duct; a second ventilation chamber is provided in the connecting rod, and the first ventilation chamber is connected to the second ventilation chamber; a third ventilation chamber is provided in the supporting block, and the second ventilation chamber is connected to the third ventilation chamber, and the third ventilation chamber is also connected to the airbag.

[0020] By adopting the above technical solution, the blower uses the first ventilation cavity, the second ventilation cavity and the third ventilation cavity that are connected to each other to deliver gas to or exhaust gas from the airbag, thereby causing the airbag to expand or contract.

[0021] 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 block is rotatably connected to the connecting rod.

[0022] By adopting the above technical solution, the second connecting blocks are arranged on both sides of the first connecting block, and the second connecting blocks are rotatably connected to the connecting rod, so that after the first connecting block is connected with the air duct, it does not rotate with the connecting rod, thereby improving the stability of the connection between the air duct and the first ventilation cavity.

[0023] Optionally, a receiving groove is provided on the peripheral side of the support block, and the receiving groove is used to receive the airbag.

[0024] By adopting the above technical solution, the airbag can be accommodated in the storage groove when it shrinks, providing space for the dirt brushed out by the brush to be removed.

[0025] Optionally, a side of the support block close to the second driving member is connected to a discharge block, and an inclined surface is provided on the discharge block.

[0026] By adopting the above technical solution, the discharge block reduces the possibility that the dirt will accumulate on the discharge block and cannot be discharged from the water intake pipe after falling through the inclined surface.

[0027] Optionally, a slide rail is provided in the shell, a slider is connected to the second driving member, and the slider is slidably connected to the slide rail.

[0028] 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 of unstable operation of the cleaning member due to vibration or deviation, thereby improving the reliability of the cleaning system.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 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, so that the cleaning member cleans the inner wall of the water intake pipe, reducing the possibility of dirt accumulation on the inner wall of the water intake pipe and affecting the water quality.

[0031] 2. By setting up an airbag, after the brush has finished cleaning, the airbag is inflated and abutted against the inner wall of the water intake pipe, and under the control of the first driving member, the inner wall of the water intake pipe is scraped from top to bottom, pushing the dirt that the brush has not cleaned out of the water intake pipe, further improving the cleaning effect of the cleaning member. After the cleaning of the inner wall of the water intake pipe is completed, the airbag remains in an inflated state to block the movable opening, reducing the possibility of water flowing into the shell when the direct drinking machine delivers drinking water. At the same time, when the direct drinking machine is not used for a long time, the airbag remains in an inflated state to block the pipe mouth of the water intake pipe, reducing the possibility of dust or gaseous pollutants in the air entering the water intake pipe, further reducing the impact of dirt on water quality.

[0032] 3. The airbag can be accommodated in the storage groove through contraction, providing space for the dirt brushed out by the brush to be removed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1 -Attached Figure 7 , further details of this application are given.

[0042] The embodiment of the present application discloses a direct drinking machine. Figure 1 and Figure 2 As shown, 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 a filter element 101. In the present embodiment, two filter elements 101 are provided. The filter element 101 is connected to an inlet pipe and an outlet pipe 102. The inlet pipe is used for municipal tap water to enter the direct drinking machine. The filter element 101 is provided with PP cotton, activated carbon rods and RO reverse osmosis membranes, etc., which can effectively remove harmful substances such as rust, sand and gravel, bacteria, heavy metal ions and residual chlorine in municipal tap water, so that the outflowing water meets the direct drinking standard, thereby improving water quality safety and user experience. The water intake pipe 3 is connected to the outlet pipe 102, and the drinking water filtered from the filter element 101 enters the water intake pipe 3 through the outlet pipe 102, so that people can take water for drinking at the water intake pipe 3.

[0043] like Figure 2 and Figure 3As shown, the cleaning system 2 is located above the water intake pipe 3 and includes a housing 201, which is fixedly connected to the outer shell of the water purification system. A first driving member 202 is fixedly connected within 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, to which a cleaning member 205 is connected. The cleaning member 205 includes a support block 2051 fixedly connected to the connecting rod 204. The first driving member 202 can realize the lifting and lowering of the support block 2051 in the water intake pipe 3, and the second driving member 203 can realize the rotation of the support block 2051. In addition, a slide rail is fixedly connected to 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 due to vibration or deviation, thereby improving the reliability of the cleaning system 2. Among them, the first driving member 202 and the second driving member 203 are both electrically connected to the controller, which can control the water output of the water purification system 1.

[0044] like Figure 4 and Figure 5 As shown, the cleaning system 2 also includes a blower 206 fixedly connected within the housing 201. A connecting base 207 is rotatably connected to the connecting rod 204. The connecting base 207 includes a first connecting block 2071 and a second connecting block 2072. The first connecting block 2071 is fixedly connected to a second connecting block 2072 on its upper and lower sides. The second connecting block 2072 is connected to the connecting rod 204 via a sealed bearing. A first ventilation chamber 4 is provided within the first connecting block 2071. The blower 206 is connected to the first ventilation chamber 4 via an air duct 2061. This ensures that when the connecting rod 204 rotates, the first connecting block 2071 does not rotate with the connecting rod 204, thereby improving the stability of the connection between the air duct 2061 and the first ventilation chamber 4. A solenoid valve is connected to the air duct 2061. Both the blower 206 and the solenoid valve are electrically connected to a controller. The cooperation between the blower 206 and the solenoid valve allows the airbag 2053 to remain inflated or deflated.

[0045] like Figure 5 and Figure 6 As shown, a second ventilation cavity 5 is defined in the connecting rod 204 , and the second ventilation cavity 5 is communicated with the first ventilation cavity 4 .

[0046] like Figure 6 and Figure 7As shown, a plurality of third ventilation cavities 6 are defined on the support block 2051. In this embodiment, eight third ventilation cavities 6 are defined, and the third ventilation cavities 6 communicate with the second ventilation cavities 5. An airbag 2053 is connected to the support block 2051, and the airbag 2053 communicates with the third ventilation cavities 6. Through the coordination 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, thereby causing the airbag 2053 to expand or contract.

[0047] like Figure 4 As shown, the cleaning member 205 further includes a brush 2052 fixedly connected to the connecting rod 204. The brush 2052 is arranged in a spiral. 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. As the brush 2052 rotates with the connecting rod 204, the spiral arrangement allows dirt to be transported out of the water intake pipe 3 as the brush 2052 rotates, further improving the cleaning effect on the inner wall of the water intake pipe 3.

[0048] When the brush 2052 cleans the inner wall of the water intake pipe 3, the blower 206 draws air to shrink the airbag 2053, thereby leaving space for the dirt removed by the brush 2052 to be removed. After the brush 2052 finishes cleaning, the blower 206 inflates the airbag 2053, which, under the control of the first driving member 202, scrapes the inner wall of the water intake pipe 3 from top to bottom, pushing out dirt not cleaned by the brush, thereby further improving the cleaning effect.

[0049] At the same time, if Figure 4 and Figure 6 As shown, the support block 2051 is fixedly connected to a discharge block 2054 on one side close to the brush 2052. The discharge block 2054 is provided with an inclined surface, which reduces the possibility that dirt will accumulate on the discharge block 2054 after falling and cannot be discharged from the water intake pipe 3.

[0050] In addition, if Figure 6 As shown, a receiving groove 7 is provided on the peripheral side of the support block 2051. The airbag 2053 can be accommodated in the receiving groove 7 after being contracted, providing a discharge space for dirt when the brush 2052 rotates for cleaning.

[0051] like Figure 4As shown, a movable opening 2011 is provided at the bottom of the housing 201. A 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 it. When the brush 2052 is operating, the controller controls the water purification system 1 to discharge water to clean dirt, blocking the movable opening 2011. This reduces the possibility of water entering the housing 201 and affecting the performance of the first and second driving members 202 and 203. Furthermore, after the inner wall of the water intake pipe 3 is cleaned, the airbag 2053 remains inflated and, under the control of the second driving member 203, moves to the movable opening 2011, blocking the movable opening 2011. This reduces the possibility of water entering the housing 201 when drinking water is drawn.

[0052] The implementation principle of a direct drinking machine in the embodiment of the present application is as follows:

[0053] When the inner wall of water intake pipe 3 needs to be cleaned, the controller activates the first drive member 202, the second drive member 203, the blower 206, and the solenoid valve. The blower 206 and the solenoid valve cooperate to retract the airbag 2053 into the storage slot 7. With the cooperation of the first and second drive members 202, 203, the brush 2052 cleans the inner wall of water intake pipe 3. Simultaneously, while brush 2052 is cleaning, the controller controls the water purification system 1 to intermittently deliver water, leveraging the water flow and the cleaning action of brush 2052 to enhance the cleaning effect on the inner wall of water intake pipe 3.

[0054] After brush 2052 has been cleaning for a while, second drive member 203 stops operating. At this point, airbag 2053, under the action of first drive member 202, moves upward for a distance. Air blower 206 and the solenoid valve cooperate to keep airbag 2053 inflated. Under the control of first drive member 202, airbag 2053 scrapes the inner wall of water intake pipe 3 from top to bottom, pushing dirt not removed by brush 2052 out of water intake pipe 3, further improving the cleaning effect.

[0055] After the airbag 2053 is cleaned, the first driving member 202 controls the support block 2051 to move to the movable opening 2011, so that the inflated airbag 2053 blocks the movable opening 2011, thereby reducing the possibility of water entering the housing 201 during water collection. 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 nozzle of the water intake pipe 3, so that the airbag 2053 blocks the nozzle of the water intake pipe 3, reducing the possibility of dust or gaseous pollutants in the air entering the water intake pipe 3, further reducing the impact of dirt on water quality.
