[0057] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0058] Example

[0059] First, see Figure 1 In order to facilitate the introduction of the fountain pump 2 described below, this embodiment first introduces a dining table, which includes a table top 11, a decoration groove 12 and a pot 15.

[0060] The scenery groove 12 is arranged in the middle of the table top 11. The scenery groove 12 has a water leakage port 13 and an overflow port 14, and the overflow port 14 is located above the water leakage port 13.

[0061] The pot 15 is annular and embedded in the table top 11 , and surrounds the outer side of the scenery groove 12 .

[0062] Second, see Figure 1~Figure 2 The present embodiment provides a fountain pump 2, which is arranged below a table top 11 of a dining table. The fountain pump 2 includes a first pump chamber 3, a pressure regulating mechanism 5 and an external pipe 6.

[0063] The first pump chamber 3 is connected to a pump inlet 31 and a pump outlet 32. The first pump chamber 3 has a first impeller (not shown). The second impeller is used to transport liquid medium (water). The water leakage port 13 and the overflow port 14 are both connected to the pump inlet 31.

[0064] The pressure regulating mechanism 5 is used to connect the pump outlet 32 ​​and the nozzle 16. The nozzle 16 is arranged in the scenery groove 12 and connected to the pump outlet 32, and is used to form a fountain in the scenery groove 12 to enhance the viewing and entertainment.

[0065] The external pipe 6 is used to connect the cooling mechanism and the pump outlet 32. The cooling mechanism is arranged on the table top 11, and is used to cool the bowls placed on the table top 11.

[0066] The fountain pump 2 is applied to the dining table, and the water outlet pressure of the nozzle 16 is adjusted by the pressure regulating mechanism 5 to form a fountain with variable height and trajectory, which enhances the viewing and entertainment. The setting of the external pipe 6 provides convenience for the connection between the cooling mechanism and the pump outlet 32. The cooling mechanism can be used to cool the dipping bowl, for example, to avoid the problem that the hot ingredients cannot be quickly cooled after contacting the dipping sauce and seasoning due to the temperature rise of the dipping sauce and seasoning in the dipping bowl after repeated use, which affects the eating (burning the mouth).

[0067] The cooling mechanism includes a protrusion arranged on the upper side of the table top 11, the protrusion matches the depression at the bottom of the bowl, the interior of the protrusion has a cavity, the cavity is connected to a cooling water inlet 71 and a cooling water outlet 72, the cooling water inlet 71 is connected to the pump outlet 32, and the cooling water outlet 72 is connected to the pump inlet 31 to realize the circulation of water, so that the water delivered by the fountain pump 2 can cool the bowl placed on the protrusion.

[0068] The pressure regulating mechanism 5 includes a pressure regulating tube 51 , a pressure regulating plug 52 and a pressure regulating rod 53 .

[0069] The pressure regulating pipe 51 has a pressure regulating inlet 54 and a pressure regulating outlet 55 . The pressure regulating inlet 54 is connected to the pump outlet 32 ​​, and the pressure regulating outlet 55 is connected to the nozzle 16 .

[0070] The pressure regulating plug 52 is slidingly and sealingly fitted in the pressure regulating pipe 51 , and the pressure regulating inlet 54 and the pressure regulating outlet 55 are both located below the pressure regulating plug 52 .

[0071] One end of the pressure regulating rod 53 is connected to the pressure regulating plug 52 .

[0072] By moving the pressure regulating rod 53 up and down, the pressure regulating plug 52 can be moved up and down to adjust the water outlet pressure of the spray head 16.

[0073] In order to facilitate the upward and downward movement of the pressure regulating rod 53 , the fountain pump 2 further includes a driving mechanism, which includes a bracket 91 , an inner gear ring 92 , a driving rotating rod 93 , a gear 94 and a pressure regulating transmission rod 95 .

[0074] The bracket 91 is arranged at a designated position to play a supporting role.

[0075] The inner ring gear 92 is fixed to the bracket 91 .

[0076] One end of the driving rotating rod 93 is rotatably connected to the bracket 91 , and the other end is rotatably connected to the middle part of the gear 94 .

[0077] The gear 94 meshes with the inner side of the ring gear 92 and is rotatable about the axis of the ring gear 92 .

[0078] One end of the pressure regulating transmission rod 95 is rotatably connected to the middle part of the gear 94, and the other end is rotatably connected to the pressure regulating rod 53. The length of the pressure regulating transmission rod 95 can be selected according to installation requirements.

[0079] The driving rod 93 can drive the gear 94 to rotate around the axis of the inner ring 92 under the drive of a power source such as a motor, thereby driving the pressure regulating rod 53 and the pressure regulating plug 52 to move up and down through the pressure regulating transmission rod 95 to adjust the water outlet pressure of the nozzle 16.

[0080] Furthermore, a filter screen 56 is provided at the pressure regulating outlet 55. The filter screen 56 is cylindrical and is covered at the pressure regulating outlet 55. Water enters the nozzle 16 after passing through the filter screen 56. This can not only prevent debris in the water from entering the nozzle 16 and causing blockage, but also prevent the diners' experience from being affected by debris carried by the water entering the scenery slot 12. In addition, during the up and down movement of the pressure regulating plug 52, the water pressure near the filter screen 56 is in a fluctuating state, which helps to prevent the intercepted debris from adhering to the filter screen 56 and clogging the filter holes, that is, it is conducive to keeping the filter screen 56 unobstructed.

[0081] The fountain pump 2 also includes a second pump chamber 4 which is independent of the first pump chamber 3. The second pump chamber 4 includes a second impeller (not shown in the figure). The second impeller is used to transport gaseous medium (air).

[0082] The dining table also includes an air outlet 17 connected to the second pump chamber 4; the air outlet 17 is arranged above the table board 11 and between the scenery groove 12 and the pot 15, and multiple air outlets 17 are evenly arranged around the scenery groove 12. The upward wind generated by the air outlet 17 can form an annular wind curtain between the pot 15 and the scenery groove 12. On the one hand, the wind curtain can isolate the scenery groove 12 and the pot 15, which can prevent the high-temperature water vapor generated in the pot 15 from affecting the water temperature of the fountain in the scenery groove 12 to ensure the effect of the cooling mechanism, and prevent the fountain in the scenery groove 12 from splashing outside the air curtain or even splashing into the pot 15; on the other hand, the wind curtain can take away the high-temperature water vapor generated in the pot 15 upwards to prevent the high-temperature water vapor from affecting diners in other seats. In addition, in a dining environment where oil smoke needs to be exhausted (frying, grilling), the wind curtain can also cooperate with a smoke hood mounted above the dining table to improve the efficiency of oil smoke exhaust.

[0083] The fountain pump 2 further includes a flow regulating mechanism 8, which is used to connect the second pump chamber 4 and the air outlet 17. The flow regulating mechanism 8 includes a flow regulating tube 81, a flow regulating plug 82 and a flow regulating rod 83.

[0084] The opposite side of the flow regulating tube 81 has a flow regulating inlet 84 and a flow regulating outlet 85 , and the flow regulating inlet 84 is located above the flow regulating outlet 85 ; the flow regulating inlet 84 , the second pump chamber 4 and the air outlet 17 are connected in sequence.

[0085] The flow regulating plug 82 is slidably sealed in the flow regulating tube 81 , and is used to partially or completely block the flow regulating outlet 85 , so as to adjust the air volume of the air outlet 17 by adjusting the flow area of ​​the flow regulating outlet 85 .

[0086] The flow regulating rod 83 slides and seals through the top of the flow regulating tube 81 , and the lower end of the flow regulating rod 83 is connected to the flow regulating plug 82 .

[0087] By moving the flow regulating rod 83 up and down, the flow regulating plug 82 can be driven to move, so as to adjust the flow area of ​​the flow regulating outlet 85 and the air volume of the air outlet 17 .

[0088] In order to facilitate the upward and downward movement of the flow regulating rod 83, the driving mechanism also includes a flow regulating transmission rod 96, one end of which is rotatably connected to the middle of the gear 94, and the other end is directly or indirectly connected to the flow regulating rod 83. The flow regulating mechanism 8 is associated with the pressure regulating mechanism 5 so that the air volume of the air outlet 17 is positively correlated with the water outlet pressure of the nozzle 16. When the water outlet pressure of the nozzle 16 is relatively low, the height of the fountain is relatively low, and the water is not easily splashed outside the scenery groove 12, and the air volume of the air outlet 17 can be in a relatively low state; when the water outlet pressure of the nozzle 16 is relatively high, the height of the fountain is relatively high, and the air volume of the air outlet 17 is in a relatively high state to prevent the water from splashing outside the scenery groove 12.

[0089] In this embodiment, preferably, the flow regulating transmission rod 96 is indirectly connected to the flow regulating rod 83, so that the flow regulating rod 83 is subjected to a force in a vertical direction to avoid affecting the sealing effect between the flow regulating rod 83 and the flow regulating tube 81. Specifically:

[0090] The driving mechanism further includes a parallelogram connecting rod structure 97 and an arc-shaped constraint track 98 .

[0091] like Figure 2 As shown, the parallelogram connecting rod structure 97 includes four connecting rods that are rotatably connected end to end in sequence, and four vertices 972, two of which are flush in the vertical direction; the upper end of the flow regulating rod 83 is connected to one of the laterally arranged connecting rods 971, and one end of the flow regulating transmission rod 96 is rotatably connected to the transfer rod 961, and one end of the transfer rod 961 is connected to the laterally arranged connecting rod 971.

[0092] The arc-shaped constraint track 98 is located on the bracket 91 ; there are two arc-shaped constraint tracks 98 , which are respectively used to guide the movement of the two upper vertices 972 of the parallelogram linkage structure 97 .

[0093] While driving the rotating rod 93 to rotate to drive the gear 94 to rotate and rotate along the inner side of the inner gear ring 92, the flow regulating rod 83 can be driven along the inner side of the inner gear ring 92 through the transfer rod 961 and the aforementioned connecting rod 971. Figure 2The dotted line shown moves vertically up and down (in the process of the gear 94 rotating along the inner side of the inner gear ring 92, the angle between the flow regulating transmission rod 96 and the adapter rod 961 will adaptively change). In this way, the flow regulating rod 83 is only subjected to the force in the vertical direction, avoiding affecting the sealing effect between the flow regulating rod 83 and the flow regulating tube 81 to prevent air leakage.

[0094] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. In the absence of conflicts, the embodiments of the present application and the features in the embodiments may be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
