DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] In the description of the embodiments of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0035] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a replaceable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0036] At present, people travel frequently and want to drink water in parks, tourist attractions and other places but do not bring water with them. The price of bottled water in the park’s canteen is expensive, and many outdoor places have begun to set up drinking water places with direct drinking machines. However, the water outlet of the existing direct drinking machine is fixed in height and cannot adapt to people of all heights. Some people need to bend down too low to drink water, which seriously affects the user experience. The present application provides a direct drinking machine, which is convenient for pedestrians to adjust the height and angle of the water outlet by setting the water outlet on a water outlet that can be rotated in the vertical direction, so as to adjust the curvature of the sprayed water, thereby meeting the drinking water needs of people of different heights, and effectively solving the technical problem that the height of the water outlet cannot be adjusted in the prior art.

[0037] In addition, the present application also found that the existing direct drinking machines still have the following problems: the way to open the machine is to bend the switch by hand, because it is inconvenient to open the switch by hand when drinking direct drinking water; the existing direct drinking machines can only drink directly, which can only meet one way, and it is difficult to use containers to receive drinking water. Some pedestrians who want to use containers to receive water can only return disappointed. The appearance of the existing direct drinking machines is mostly square and round stainless steel, which is cold and abrupt, does not reflect the integration of people and the environment, and is not beautiful enough.

[0038] See also Figure 1-Figure 10The embodiment of the present application provides a direct drinking machine, including a direct drinking machine body 1, a first faucet 2 and a water filter 4; the first faucet 2 includes a base 21, a limiting portion 22 and a water outlet 23, and the base 21 is installed on the direct drinking machine body 1; there are two limiting portions 22, and the two limiting portions 22 are separately installed on the base 21, and the water outlet 23 is rotatably installed between the two limiting portions 22 in the vertical direction; a first water outlet 231 is provided on the water outlet 23, and the first water outlet 231 is connected to the water filter 4.

[0039] More specifically, the main body 1 of the direct drinking machine is in the shape of a rod, and the main body 1 of the direct drinking machine is mainly used to accommodate a drainage pipe, a water pipe 7 and other components, which can make the direct drinking machine look simple and beautiful as a whole; the first faucet 2 is installed on the top of the direct drinking machine main body 1, and the two limiting parts 22 are vertically arranged. The two limiting parts 22 are extended from the top edge of the base 21 in the horizontal direction, and a rotation space for installing the water outlet 23 is formed between the two limiting parts 22. The water outlet 23 and the rotation space can both be in the shape of a flat cylinder, and the diameter of the water outlet 23 is slightly smaller than the diameter of the rotation space, so that the water outlet 23 can rotate in the rotation space, and the rotation angle range of the water outlet 23 is -60° to 60°; the first water outlet 231 is arranged on the side of the water outlet 23 away from the base 21, and the water filter 4 passes through the main body 1 of the direct drinking machine and the base 21 through the water pipe 7 to communicate with the first water outlet 231.

[0040] Further, in this embodiment, please refer to Figure 6-Figure 8 The first faucet 2 further includes a knob 24. The water outlet 23 is hinged between the two limit parts 22 through a rotating shaft, and the knob 24 is coaxially connected to the rotating shaft. The two ends of the rotating shaft respectively penetrate the two limit parts 22, and the rotating shaft can rotate along its own axis. The water outlet 23 is fixedly sleeved on the rotating shaft; there are two knobs 24, and the two knobs 24 are respectively arranged at the two ends of the rotating shaft, that is, the rotating shaft, the water outlet 23 and the knob 24 can rotate together. By rotating the knobs 24 on both sides, the rotating shaft and the water outlet 23 can be rotated, thereby changing the height and angle of the first water outlet 231, so as to adjust the sprayed water to have a suitable curvature, which is suitable for pedestrians to drink directly and meet the drinking water needs of people with different heights.

[0041] More specifically, the present application may also be provided with a handle, which is arranged on the curved side wall of the water outlet 23. The rotation of the rotating shaft and the water outlet 23 can also be achieved through the handle. However, the present application preferably has a knob 24, which is convenient for pedestrians to operate and does not affect pedestrians drinking water. In addition, a torsion spring may be provided in the first faucet 2. When the pedestrian rotates the knob 24, the torsion spring will also be deformed. When the pedestrian finishes drinking water and releases the rotating knob 24, the knob 24 will rotate in the opposite direction through the elastic action of the torsion spring, so that the water outlet 23 returns to its original position, thereby realizing that the first water outlet 231 automatically returns to its original position to facilitate the use of the next pedestrian.

[0042] Furthermore, in this embodiment, a second faucet 3 is included, which is installed on the direct drinking machine body 1 and is lower than the first faucet 2; the second faucet 3 is provided with a second water outlet, which is connected to the water filter 4. The higher first faucet 2 is mainly used to meet the direct drinking needs of adults, and the lower second faucet 3 is mainly used to meet the direct drinking needs of children. The height difference between the first faucet 2 and the second faucet 3 is 20cm to 40cm. The first faucet 2 and the second faucet 3 at different heights can meet the drinking height requirements of most people.

[0043] More specifically, the second faucet 3 can also be provided with a water outlet 23 that can rotate in the vertical direction, and the second water outlet is arranged on the water outlet 23, so that when the child drinks directly, the height and angle of the water outlet can be adjusted by the knob 24, thereby adjusting the sprayed water to have a suitable curvature, which is convenient for the child to drink directly. Moreover, by using the first faucet 2 and the second faucet 3 of different heights and the first water outlet 231 and the second water outlet with adjustable height, the adjustment height range of the direct drinking water spray can be further expanded, which can meet the drinking height requirements of most people. Of course, the present application can be installed with 1 to 2 faucets, or 3 or more faucets, but usually 1 to 2 faucets are enough to meet the drinking height requirements of most people.

[0044] Furthermore, in the present embodiment, a pedal is also included, and the pedal is used to control the water outflow from the first water outlet 231 and the second water outlet. That is, the first faucet 2 and the second faucet 3 adopt common foot-operated faucets, which are composed of a main valve, an auxiliary valve and a hydraulic pipe. Specifically, it refers to a foot-operated hydraulic control water valve that controls its opening and closing by the water pressure of the pipeline itself. Its main purpose is to overcome the shortcomings of the existing mechanical water valve, which needs to be operated by hand contact when using water, which is easy to cause disease transmission, and the induction water valve has a complex structure, electrical safety hazards, and wastes electric energy. When the foot-operated switch of the auxiliary valve is stepped on by foot, the auxiliary valve is opened, the hydraulic pipe is connected, the water inlet passes through the pressure relief groove, and a passage is formed between the hydraulic pipe and the water outlet. There is no water pressure on the upper side of the main valve piston. Under the action of the water pressure below, the piston moves upward, and the valve disc is separated from the water hole. The main valve is opened, and the first water outlet 231 and the second water outlet spray out direct drinking water. When the foot releases the pedal switch of the auxiliary valve, the hydraulic pipe is blocked. The water pressure on both sides of the main valve piston is restored to balance. Under the action of the spring, the valve disc is pressed against the water hole again, so that the main valve is closed, and the first water outlet 231 and the second water outlet no longer spray out direct drinking water.

[0045] Further, in this embodiment, please refer to Fig.10 The pedal includes a first pedal 51 and a second pedal 52 which are separated from each other. The first pedal 51 and the second pedal 52 are used to control the water discharge from the first water outlet 231 and the second water outlet respectively. The area of ​​the second pedal 52 is smaller than that of the first pedal 51. Since the first pedal 51 and the second pedal 52 are of different sizes, it is convenient for children and adults with feet of different sizes to step on them. Moreover, the first pedal 51 and the second pedal 52 are arranged together on the periphery of the direct drinking machine body 1. The first pedal 51 and the second pedal 52 are in the shape of a plum blossom, so that the pedals installed on the direct drinking machine body 1 will not appear very abrupt, and have the characteristics of simplicity and beauty. During installation, it is necessary to ensure that there is a certain distance between the pedal and the ground, so that it is convenient for children and adults to step on the first pedal 51 and the second pedal 52 downward.

[0046] Furthermore, in the present embodiment, preferably, in the above-mentioned direct drinking machine, the first faucet 2 and the second faucet 3 are respectively arranged on both sides of the direct drinking machine body 1, so that the water spraying directions of the first water outlet 231 and the second water outlet are opposite, which can facilitate adults and children to drink directly at the same time, and has great convenience.

[0047] Further, in this embodiment, please refer to Figure 1, and also includes a water receiving tray 6, and there are two water receiving trays 6, which are respectively installed below the first water outlet 231 and below the second water outlet. When pedestrians use the first faucet 2 and the second faucet 3 to drink directly, some of the water sprayed from the first water outlet 231 and the second water outlet will inevitably fall, and the water receiving tray 6 is arranged below the first water outlet 231 and the second water outlet, which can not only catch the fallen water to facilitate subsequent drainage, but also effectively prevent the fallen water from being sprinkled on the clothes or shoes of pedestrians.

[0048] Furthermore, in this embodiment, the water receiving tray 6 is tilted, the lower end of the water receiving tray 6 is connected to the direct drinking machine body 1, the middle of the water receiving tray 6 is recessed to form a drainage channel, and a drainage pipe is installed at the lowest point of the drainage channel. The tilted water receiving tray 6 and the drainage channel formed by the recess are conducive to gathering the water dropped by pedestrians when drinking directly to the lowest point of the drainage channel, so that the gathered water can be discharged from the drainage pipe, and the water receiving tray 6 with a shape of low in the middle and high on both sides can also play an anti-splashing effect, which can effectively prevent the dropped water from falling into the water receiving tray 6 and splashing on the clothes of pedestrians, and has good practicality.

[0049] More specifically, see Figure 6 A drain port 61 is provided at the lowest point of the drain channel, and the drain pipe is connected to the drain port 61; in addition, in order to make the appearance of the direct drinking machine more beautiful, the drain pipe can be wrapped and arranged inside the direct drinking machine body 1, and the water outlet end of the drain pipe is connected to the underground drainage line; please refer to Figure 5 The width of the water receiving tray 6 gradually increases from the higher end to the lower end. On the one hand, since the water dropped during direct drinking is often concentrated in the middle of the water receiving tray 6 and near the water outlet (that is, the lower end), the width of the lower end needs to be set larger to facilitate the water receiving tray 6 to better receive water. On the other hand, the shape of the water receiving tray 6 configured in this way is similar to leaves or tree trunks. Combined with the rod-shaped direct drinking machine body 1, the entire direct drinking machine looks like a small tree, which makes it convenient for the direct drinking machine to be integrated into the environment of the park without appearing very abrupt.

[0050] Further, in this embodiment, please refer to Figure 2 The base 21 is rotatably mounted on the main body 1 of the direct drinking machine, that is, the entire first faucet 2 is rotatably mounted on the main body 1 of the direct drinking machine. By rotating the entire first faucet 2, the first water outlet 231 is no longer located above the corresponding water receiving tray 6, so that there is enough space below the first water outlet 231 for people to collect drinking water in containers.

[0051] More specifically, the first faucet 2 can be limited to move 180° in a certain direction, that is, the rotation angle range of the first faucet 2 is -180° to 180°, so as to avoid the water pipe 7 from getting tangled when rotating; of course, in order to avoid the water pipe in the direct drinking machine body 1 from rotating due to the rotation of the first faucet 2, the water pipe of the first faucet 2 and the water pipe of the direct drinking machine body 1 can also be set discontinuously, and then the base 21 and the top of the direct drinking machine body 1 can be rotatably connected through a rotating joint. The setting of the rotating joint can ensure that the base 21 can still ensure that the direct drinking machine body 1 and the base 21 are still in a sealed state after the rotation, thereby effectively preventing the direct drinking water from leaking from the connection between the direct drinking machine body 1 and the base 21.

[0052] Further, in this embodiment, please refer to Figure 3 and Figure 5 The water filter 4 includes a box body 41 and a filter element 42 disposed in the box body 41. The filter element 42 is connected to the first water outlet 231 and the second water outlet through a water pipe 7. The water filter 4 is supplied with water by a municipal water pipe. The tap water is supplied to the box body 41, and the water is filtered through the filter element 42 in the box body 41 for direct drinking by pedestrians. Three filter elements 42 can be built into the box body 41. The three filter elements 42 are a PP cotton filter element and two ultrafiltration filter elements. The PP cotton filter element, the ultrafiltration filter element and the ultrafiltration filter element with better precision are connected in series in sequence. The tap water passes through the PP cotton filter element and the two ultrafiltration filter elements in sequence, which can filter the tap water well and meet the standard of direct drinking water.

[0053] More specifically, the water pipe 7 and the water filter 4 can be buried underground, which can effectively prevent pedestrians from damaging the water pipe 7 and the water filter 4. The water filter 4 is provided with a detachable box cover. When replacing the filter element 42, the maintenance personnel only need to open the cover and unplug the water pipe port to replace the new filter element 42.

[0054] The beneficial effects of the present application are as follows: (1) By providing two faucets at different heights and arranging the water outlet on a water outlet portion 23 that can rotate in the vertical direction, it is convenient for pedestrians to adjust the height and angle of the water outlet to adjust the arc of the sprayed water, thereby meeting the drinking height requirements of people of different heights; (2) By stepping on the switch, one can lower his head and drink directly without raising his hand to control the switch, and there is zero contact with the water dispenser, which ensures the cleanliness of the hands and effectively reduces the uncivilized behavior of pedestrians washing their hands with drinking water after drinking because they dislike the dirty switch handle; (3) The use of a rotatable faucet ensures that there is enough space under the water outlet for people to collect drinking water in containers; (4) The appearance of the direct drinking machine and its good color matching make it easy to blend into the natural environment, and it is gentle, simple and not abrupt.

[0055] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0056] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
