Pipeline machine

Abstract

The invention relates to a pipeline machine which comprises a water tank with an exhaust hole communicated with the interior of the water tank. The shell is provided with an air outlet hole; and the communicating structure communicates with the exhaust hole and the air outlet hole and is used for exhausting air in the water tank. Gas in the water tank can enter the connecting channel through the exhaust hole and enter the air outlet through the connecting channel, and finally the gas is discharged out of the pipeline machine through the air outlet, so that the problem of water leakage caused by burst of the water tank due to overhigh air pressure in the water tank is avoided. Moreover, when the pipeline machine accidentally topples or inclines, if the inclination angle of the pipeline machine is small, water in the water tank can stay in the connecting channel after entering the exhaust hole, and cannot flow out of the air outlet hole. And if the inclination angle of the pipeline machine is large, water in the water tank only flows into the outside of the pipeline machine after entering the air outlet hole, so that an electrical part in the pipeline machine cannot be contacted with water, and potential safety hazards or safety accidents are avoided.

Description

Existing pipeline machines include water inlet pipes, water inlet control components, water tanks, water tank covers, drain pipes and water treatment equipment, etc. Water is led into the water tank through the water inlet pipe and flows into the water treatment equipment through the drain pipe.

[0003] When the water in the water tank reaches a certain height, the water inlet control component is closed and no more water is allowed to enter. Since the water tank is full of air, when the water tank is filled with water and drained, if the air is not vented smoothly, it will affect the inlet and outlet flow. Especially when water flows into the water tank, the water will squeeze the air in the water tank out of the water tank. Therefore, it is necessary to open an air vent on the water tank or the water tank cover.

[0004] However, when the pipeline machine accidentally topples or tilts (for example, it is accidentally knocked over), the water in the water tank can easily flow out from the exhaust hole, thereby affecting the user experience and even causing the electrical parts in the machine to come into contact with water, resulting in safety accidents or leaving safety hazards.

[0056] Referring to FIG1 , FIG1 shows a schematic diagram of the structure of a pipeline machine in an embodiment of the present application. The pipeline machine provided in an embodiment of the present application includes a water tank 10, a shell 20 and a connecting structure 30. Further, referring to FIG2 , FIG2 shows a schematic diagram of the decomposition of the pipeline machine in the embodiment of FIG1 , wherein the water tank 10 has an exhaust hole 11 connected to its interior, the shell 20 has an air outlet 21, and the connecting structure 30 is connected to both the exhaust hole 11 and the air outlet 21 for discharging the contents of the water tank 10.

[0057] Specifically, referring to FIG. 4 , FIG. 4 shows a cross-sectional schematic diagram of the pipeline machine in the embodiment of FIG. 1 , from which it can be known that the gas in the water tank 10 can enter the connecting structure 30 through the exhaust hole 11, and enter the air outlet 21 through the connecting structure, and finally the gas is discharged to the outside of the pipeline machine through the air outlet 21, thereby avoiding the problem of excessive air pressure in the water tank 10 causing the water tank 10 to burst and leak. In addition, when the pipeline machine accidentally topples or tilts, if the inclination angle of the pipeline machine is small, the water in the water tank 10 will stay in the connecting structure 30 after entering the exhaust hole 11, and will not flow out from the air outlet 21. If the inclination angle of the pipeline machine is large, the water in the water tank 10 will only flow to the outside of the pipeline machine after entering the air outlet 21, and will not cause the electrical parts in the pipeline machine to encounter water, thereby avoiding the occurrence of safety hazards or safety accidents.

[0058] In some embodiments of the present application, referring to FIG. 3 and FIG. 4 , the connecting structure 30 includes an exhaust pipe 32 and a waterway plate 33. The exhaust pipe 32 has an exhaust channel 31, one end of which is connected to the exhaust hole 11. The waterway plate 33 has a connecting channel 34, one end of which in the extension direction is connected to the other end of the exhaust channel 31, and the other end of the connecting channel 34 is connected to the air outlet 21. In this way, the gas in the water tank 10 passes through the exhaust channel 31 of the exhaust pipe 32 and the connecting channel of the waterway plate 33 in sequence, and is finally discharged into the atmosphere outside the pipeline machine through the air outlet 21.

[0059] It is understandable that, in other embodiments, one end of the exhaust pipe 32 may be communicated with the air outlet 21, and the connecting channel 34 may be communicated with the air outlet 11. In some other embodiments, the connecting structure 30 may also include only the exhaust pipe 32 or the waterway plate 33, that is, the gas from the air outlet 11 enters the air outlet 21 through the exhaust pipe 32 or the connecting channel 34 alone.

[0060] In actual use, the waterway plate 33 has multiple waterways integrated inside, and the water in the water tank 10 flows into the various water outlets of the pipeline machine or the water inlet of the water treatment equipment through the waterway plate 33, that is, the waterway plate 33 plays the role of connecting the various components in the pipeline machine, and by integrating multiple waterways in the waterway plate 33, the number of water pipes in the pipeline machine can be reduced, thereby improving the integration of the pipeline machine. By integrating the connecting channel 34 on the waterway plate 33, the length of the exhaust pipe 32 can be reduced, and during production and assembly, the water tank 10 and the waterway plate 33 can be pre-assembled and integrated in one piece, and then assembled and fixed with the housing 20, effectively improving the production and assembly efficiency.

[0061] Furthermore, the air outlet 21 is located on the outer wall of the housing 20, and its height is higher than that of the exhaust hole 11. The connecting pipe is L-shaped, and the exhaust pipe 32 is a straight pipe. In order to facilitate the installation of the exhaust pipe 32, in some embodiments, the pipeline machine further includes a quick connector 40. The exhaust pipe 32 is made of a hard pipe. One end of the exhaust pipe 32 is connected to the waterway plate 33 through the quick connector 40, and the other end of the exhaust pipe 32 is connected to the waterway plate 33 through the quick connector 40. When the pipeline machine is produced and assembled, the exhaust pipe 32 can be quickly connected to the water tank 10 and the waterway plate 33 through the quick connector, thereby improving the production and assembly efficiency of the pipeline machine.

[0062] It is understandable that when the exhaust pipe 32 is connected to the housing 20, the quick connector 40 can also be used to connect the exhaust pipe 32 to the housing 20. In some other embodiments, the exhaust pipe 32 can also be connected to the waterway plate 33, the water tank 10 or the housing 20 at only one end through the quick connector 40, and the other end is connected to the waterway plate 33, the water tank 10 or the housing 20 by integral molding or the following direct plugging method.

[0063] Specifically, in some embodiments, referring to FIG. 5 , the quick connector 40 includes a gland 41 and a claw 42. The water tank 10 is provided with an exhaust column 14, and the exhaust column 14 is provided with a first fixing hole 12. The exhaust hole 11 is connected to the first fixing hole 12. The gland 41 is arranged in the first fixing hole 12 and connected to the exhaust column 14 by crimping or clamping, so that the gland 41 is fixed to the water tank 10. Specifically, a convex block is arranged on the circumferential side wall of the gland 41, and a fixing groove is arranged on the inner wall of the first fixing hole 12. The convex block is inserted into the fixing groove, so that the gland 41 is fixed to the exhaust column 14 to prevent the gland 41 from being dislodged under force. In some other embodiments, the gland 41 can also be fixed to the water tank 10 by ultrasonic welding.

[0064] The pressure cover 41 has a clamping hole 43, which passes through the pressure cover 41 and is connected to the first fixing hole 12. The exhaust pipe 32 is inserted into the clamping hole 43 so that the exhaust pipe 32 is connected to the exhaust hole 11. In addition, the claw 42 is sleeved on the exhaust pipe 32 and can be mutually engaged with the pressure cover 41, so that the exhaust pipe 32 is prevented from escaping from the first fixing hole 12 through the mutual cooperation between the claw 42 and the pressure cover 41.

[0065] Furthermore, when the quick connector 40 is used to connect the exhaust pipe 32 with the waterway plate 33, a waterway column 36 is provided on the waterway plate 33, and a second fixing hole 35 connected to the connecting channel 34 is provided on the waterway column 36. The pressure cover 41 is arranged in the second fixing hole 35 and is connected to the waterway column 36 by crimping or snapping. The specific connection method can refer to the installation method of the pressure cover 41 in the first fixing hole 12 as above, and will not be repeated here.

[0066] When the pressure cover 41 is installed on the waterway plate 33, the clamping hole 43 of the pressure cover 41 is connected to the second fixing hole 35, the exhaust pipe 32 is inserted into the clamping hole 43 of the pressure cover 41, and the exhaust pipe 32 is prevented from escaping from the second fixing hole 35 by the mutual cooperation between the claw 42 sleeved on the exhaust pipe 32 and the pressure cover 41.

[0067] Furthermore, when the exhaust pipe 32 is connected to the air outlet 21 of the shell 20, the quick connector 40 can also be used to connect the exhaust pipe 32 to the shell 20, that is, when the pressure cover 41 is installed on the shell 20, the clamping hole 43 of the pressure cover 41 is connected to the air outlet 21, so that the exhaust pipe 32 passing through the pressure cover 41 can be connected to the air outlet 21, and is fixed to the pressure cover 41 by the claws 42 on the exhaust pipe 32.

[0068] Specifically in some embodiments, the inner wall of the clamping hole 43 has a protruding limiting portion 44, which is arranged around the circumference of the exhaust pipe 32. A plurality of buckles 45 are arranged on the claw 42, and all the buckles 45 are arranged around the circumference of the claw 42. The buckle 45 is located in the clamping hole 43. When the exhaust pipe 32 is pulled out of the clamping hole 43, the buckle 45 can abut against the limiting portion 44 and prevent the exhaust pipe 32 from leaving the clamping hole 43, thereby fixing the exhaust pipe 32 in the clamping hole 43.

[0069] In actual use, the buckle 45 is made of a material with a certain elastic force, such as plastic. When the exhaust pipe 32 is inserted into the clamping hole 43, the buckle 45 is squeezed by the limiting portion 44 and elastically deformed, so that the buckle 45 can pass the limiting portion 44 and enter the clamping hole 43 with the exhaust pipe 32. After the buckle 45 enters the clamping hole 43, when the exhaust pipe 32 is pulled out of the clamping hole 43, the buckle 45 will abut against the limiting portion 44 to limit the exhaust pipe 32 from leaving the clamping hole 43, thereby achieving the effect of fixing the exhaust pipe 32.

[0070] It should be noted that in other embodiments, the quick connector 40 may also be other existing air quick connectors 40, gas-liquid common quick connectors 40, etc., as long as it can achieve quick connection between the exhaust pipe 32 and the water tank 10, and the exhaust pipe 32 and the waterway plate 33, and no limitation is made here.

[0071] In some embodiments, in order to prevent the water in the water tank 10 from flowing out from the gap between the water tank 10 and the housing 20 when the pipeline machine is tipped over, and also to ensure the exhaust effect, one end of the exhaust pipe 32 is inserted into the clamping hole 43 of the gland 41, one end of the exhaust pipe 32 is located in the first fixing hole 12, and a first sealing member 13 is provided between the exhaust pipe 32 and the inner wall of the first fixing hole 12, so that the gap between the exhaust pipe 32 and the inner wall of the first fixing hole 12 is sealed by the first sealing member 13, thereby preventing gas or water from leaking from the gap.

[0072] Furthermore, after the other end of the exhaust pipe 32 passes through the snap-in hole 43 of the pressure cover 41 on the waterway plate 33, the other end of the exhaust pipe 32 is located in the second fixing hole 35, and a second sealing member 351 is provided between the exhaust pipe 32 and the inner wall of the second fixing hole 35 to seal the gap between the exhaust pipe 32 and the inner wall of the second fixing hole 35 with the second sealing member 351, thereby preventing gas or water from leaking from the gap.

[0073] In some other embodiments, the exhaust pipe 32 may be installed without using a quick-connect joint. As shown in FIG7 , the exhaust pipe 32 is made of a hose material, an exhaust column 14 is provided on the housing 20, an exhaust hole 21 is provided on the end surface of the exhaust column 14, and the exhaust column 14 is inserted into one end of the exhaust pipe 32. In this way, the exhaust pipe 32 can be installed on the exhaust column 14, and the exhaust channel 31 in the exhaust pipe 32 can also be connected to the exhaust hole 11.

[0074] Furthermore, a waterway column 36 is provided on the waterway plate 33, and a connection hole 39 communicating with the connection channel 34 is provided on the waterway column 36, and the waterway column 36 is inserted into the other end of the exhaust pipe 32. Thus, the other end of the exhaust pipe 32 is fixed by the waterway column 36, and the exhaust channel 31 in the exhaust pipe 32 can be connected with the connection hole 39.

[0075] Furthermore, in order to prevent the exhaust pipe 32 from falling off the exhaust column 14 and the waterway column 36, the pipeline machine further includes two fasteners 37, which are sleeved on both ends of the exhaust pipe 32, one of which is used to lock the exhaust pipe 32 and the exhaust column 14, and the other fastener 37 is used to lock the exhaust pipe 32 and the waterway column 36. The fastener 37 can be a rubber ring, a clamp, etc., so that a certain pressure is applied to the exhaust pipe 32 through the fastener 37 to fix the exhaust pipe 32 on the exhaust column 14 or the waterway column 36.

[0076] In some embodiments of the present application, in addition to the gap between the exhaust pipe 32 and the water tank 10 and the waterway plate 33 needing to be sealed, the gap between the housing 20 and the waterway plate 33 also needs to be sealed during the process of gas entering the air outlet 21 from the connecting channel 31 of the waterway plate 33. To this end, referring to FIG. 6, the housing 20 is provided with an air outlet column 22, and the air outlet 21 is arranged in the air outlet column 22. The waterway plate 33 is provided with a connecting column 38, and the connecting column 38 is provided with a connecting hole 39 connected to the connecting channel 34. The pipeline machine also includes a sealing sleeve 50, which connects the air outlet column 22 and the connecting column 38, and connects the air outlet 21 and the connecting hole 39. In this way, while the air outlet 21 and the connecting hole 39 are connected by the sealing sleeve 50, the gap between the air outlet column 22 and the connecting column 38 can also be sealed by the sealing sleeve 50, thereby reducing the probability of gas and water leakage.

[0077] Specifically, the sealing sleeve 50 includes a first sealing ring 51 and a second sealing ring 52 that are connected to each other and coaxially arranged, the connecting column 38 is inserted into the air inlet and outlet hole 21, so that the connecting hole 39 on the connecting column 38 is connected to the air outlet hole 21, and the first sealing ring 51 is located between the inner wall of the air outlet hole 21 and the connecting column 38, so that the gap between the inner wall of the air outlet hole 21 and the connecting column 38 is sealed by the first sealing ring 51. In addition, the second sealing ring 52 is sleeved on the outer wall of the air outlet column 22, so that the sealing between the air outlet column 22 and the connecting column 38 is further improved by the second sealing ring 52, and the air outlet column 22 is quickly installed in place through the gap between the first sealing ring 51 and the second sealing ring 52, which is conducive to improving the assembly efficiency of the pipeline machine.

[0078] In some other embodiments, the air outlet column 22 can be inserted into the connecting hole 39. In this embodiment, the first sealing ring 51 is located between the inner wall of the connecting hole 39 and the air outlet column 22, and the second sealing ring 52 is sleeved on the outer wall of the connecting column 38. The sealing sleeve 50 can also achieve sealing of the gap between the air outlet column 22 and the connecting column 38.

[0079] It is understandable that in some other embodiments, the sealing sleeve 50 may also be a hose, and the two ends of the sealing sleeve 50 are respectively sleeved on the connecting column 38 and the air outlet column 22 to connect the connecting hole 39 and the air outlet hole 21 to each other.

[0080] In some embodiments of the present application, the pipeline machine further includes a damping block 53, the connecting structure 30 has an exhaust channel 31, the exhaust channel 31 is connected to both the exhaust hole 11 and the air outlet 21, and the damping block 31 is arranged in the exhaust channel 31, that is, the damping block 53 can be arranged in the exhaust pipe 32, and in other embodiments, the exhaust channel 31 of the connecting channel 30 can also refer to other channels connecting the exhaust hole 11 and the air outlet 21, such as the connecting channel 34 in the waterway plate 33. Among them, the airflow in the exhaust channel 31 can pass through the damping block 53, that is, the damping block 53 does not block the exhaust channel 31, and the gas can flow normally in the exhaust channel 31.

[0081] When the pipeline machine is in normal use, the gas is discharged from the air outlet 21 through the damping block 53. When the pipeline machine is overturned or tilted, after the water in the water tank 10 enters the exhaust channel 31, the damping block 53 will block the water from moving along the exhaust channel 31, preventing the water from flowing out of the air outlet 21. In addition, even if the pipeline machine is tilted greatly, such as being laid flat, the damping block 53 can block most of the water in the exhaust channel 31, so that even if water flows out of the air outlet 21, only a small amount of water will flow out, reducing the impact on the user experience.

[0082] In some embodiments, in order to enable the airflow to pass through the damping block 53, the damping block 53 is spaced apart from the inner wall of the exhaust channel 31, so that the gas can flow through the gap between the damping block 53 and the exhaust channel 31. Furthermore, a plurality of damping holes may be provided on the damping block 53, and the damping holes penetrate the damping block 53 along the flow direction of the exhaust channel 31, so that the gas can pass through the damping block 53 through the damping holes, so that the gas can flow normally in the exhaust channel 31. Optionally, the damping block 53 is provided in the exhaust pipe 32, and before installing the exhaust pipe 32, the damping block 53 may be placed in the inlet and outlet pipes 32 first, and after the exhaust pipe 32 is installed, the damping block 53 is also installed.

[0083] In some embodiments of the present application, the pipeline machine further includes a plugging structure 60, which is disposed at the air outlet 21 and has a plurality of air outlet sub-holes 61, each of which is connected to the air outlet 21 and the connecting structure 30. When the connecting structure 30 includes an exhaust pipe 32 and a waterway plate 33, the air outlet 61 is connected to the connecting channel 34 of the waterway plate 33, and the flow area of ​​each air outlet sub-hole 61 is smaller than the flow area of ​​the air outlet 21. In this way, through a plurality of air outlet sub-holes 61 with smaller areas, while ensuring that the airflow can pass normally, the probability of dust, foreign matter, mosquitoes, etc. entering the connecting structure 30 is reduced, which significantly improves the sanitary quality of drinking water and provides a safer and healthier drinking water environment for users.

[0084] In some embodiments, the blocking structure 60 includes a filter 63 and an end cap 62. The filter 63 is disposed in the air outlet 21. The end cap 62 is disposed on the housing 20 and blocks the air outlet 21. All the air outlet sub-holes 61 are disposed on the end cap 62. That is, after the filter 63 is disposed in the air outlet 21, the filter 63 is fixed in the air outlet 21 through the end cap 62. The filter 63 can be a sponge, a gauze, a filter cotton, etc., so as to ensure the normal circulation of gas while further improving the filtering effect of dust, foreign matter, mosquitoes, etc. through the filter 63, thereby improving the sanitary quality of drinking water.

[0085] Furthermore, the end cap 62 is provided with threads, and the air outlet 21 is a threaded hole, so that the end cap 62 can be installed on the housing 20 by threaded connection. In some other embodiments, the end cap 62 can also be installed on the housing 20 by interference fit or the like.

[0086] The above pipeline machine has at least the following advantages:

[0087] The gas in the water tank 10 can enter the connecting channel 30 through the exhaust hole 11, and enter the air outlet 21 through the connecting channel 30, and finally the gas is discharged to the outside of the pipeline machine through the air outlet 21, thereby avoiding the problem of excessive pressure in the water tank 10 causing the water tank 10 to burst and leak. In addition, when the pipeline machine accidentally topples or tilts, if the inclination angle of the pipeline machine is small, the water in the water tank 10 will stay in the connecting channel 30 after entering the exhaust hole 11, and will not flow out from the air outlet 21. If the inclination angle of the pipeline machine is large, the water in the water tank 10 will only flow to the outside of the pipeline machine after entering the air outlet 21, and will not cause the electrical parts of the pipeline machine to encounter water, thereby avoiding the occurrence of safety hazards or safety accidents.

[0088] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
