[0002] A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. The structural requirements and performance requirements for water pumps used in different industries and different application scenarios are also different.

[0003] The double pump used in the water supply device usually has a water outlet and a water inlet, and the water is transported to the designated container under the drive of the double pump. For a water supply device with multiple containers, if you want to achieve independent water supply control for different containers, you need to design multiple double pumps corresponding to different containers, which greatly increases the production cost;

In this case, it is necessary to design the delivery pipeline, such as setting a three-way valve or a switching valve on the pipeline, and realizing independent control of water filling of different containers by controlling the on-off control of the pipeline. However, this method is also costly, and the pipeline structure is complex, with many pipeline joints, and there are safety hazards.

[0005] Therefore, it is necessary to design a double pump with multiple water outlets, each of which can be independently controlled to open and close, with a relatively simple structure and meeting the economic requirements of water supply device production. Utility Model Content

[0034] See also Figure 1-Figure 3 The integrated self-priming double pump comprises a top cover 1, a water inlet and outlet housing 2, a suction cup assembly 3 and a driving mechanism 4. The detachable cover of the top cover 1 is arranged on the front port of the water inlet and outlet housing 2 and a water inlet 11 and at least two water outlets 12 are provided on the top cover 1. In this embodiment, two water outlets 12 are provided on the top cover 1 as an example for explanation. It can be understood that more water outlets 12 can be provided as needed. The water inlet 11 is used to access cold water inlet, and the water outlet 12 is used to fill water to the container connected thereto; the inner cavity of the water inlet and outlet housing 2 The water outlet space 22 is separated into a water inlet space 21 and at least two water outlet spaces 22. The water outlet space 22 is isolated from the water inlet space 21, and the two water outlet spaces 22 are also isolated from each other. The water outlet space 22 is connected to the water outlet 12 one by one, and the water inlet 11 is connected to the water inlet space 21. Specifically, the water inlet space 21 surrounds the outer ring of the water outlet space 22. The suction cup assembly 3 is detachably installed at the rear end of the water inlet and outlet housing 2, such as snap-fit ​​connection, bolt fixing, etc. The rear end wall of the water inlet and outlet housing 2 is provided with a plurality of groups of suction cup assemblies 3 and the water inlet space 21. The first flow holes 23, the number of each group of first flow holes 23 can be one or more, each group of first flow holes 23 corresponds to a water outlet 12, the rear end wall of the water inlet and outlet housing 2 is also provided with a plurality of groups of second flow holes 24 connecting the suction cup assembly 3 and the water outlet space 22, the number of each group of second flow holes 24 can be one or more, each group of second flow holes 24 corresponds to a water outlet 12, in this embodiment, two groups of first flow holes 23 and two groups of second flow holes 24 are provided on the water inlet and outlet housing 2, each water outlet 12 corresponds to a group of first flow holes 23 and two groups of second flow holes 24, A flow hole 23 corresponds to a group of second flow holes 24, so that the water flow paths corresponding to the two water outlets 12 are isolated from each other and do not affect each other. The suction cup assembly 3 provides suction to the water flow in the water inlet space 21 through deformation, and absorbs the water flow entering the water inlet space 21 from the water inlet 11. The suction cup assembly 3 pushes the absorbed water into the water outlet space 22 through deformation, and then pushes the water out through the water outlet 12; the driving mechanism 4 is connected to the suction cup assembly 3, and the driving mechanism 4 is used to provide power to the suction cup assembly 3 to squeeze the suction cup assembly 3 to cause it to deform.

[0035] A first flow-through hole 23 is provided with a first flow-limiting component 5, which is used to release the water flow when the suction cup component 3 provides suction to the water flow in the water inlet space 21, and to limit the water flow when the suction cup component 3 provides thrust to the water flow in the water outlet space 22; a second flow-limiting component 6 is provided with a second flow-limiting component 6, which is used to release the water flow when the suction cup component 3 provides thrust to the water flow in the water outlet space 22, and to limit the water flow when the suction cup component 3 provides suction to the water flow in the water inlet space 21. Both the first flow-limiting component 5 and the second flow-limiting component 6 are one-way valve structures;

[0036] Specifically, in this embodiment, Figure 1-Figure 3 The first flow limiting component 5 is an umbrella-shaped structure, the handle end of the umbrella-shaped structure is connected to the water inlet and outlet housing 2, the cover end of the umbrella-shaped structure covers the rear port of the first flow hole 23, and the cover end is made of a soft elastic material, such as rubber, silicone, etc. The cover end can intermittently block the first flow hole 23 under the drive of the water flow. When the water flows from the water inlet space 21 to the first flow hole 23 to the suction cup component 3, the cover end opens, thereby releasing the water in the water inlet space 21 to flow through the first flow hole 23, and when the water flows from the suction cup component 3 to the second flow hole 24 to the water outlet space 22, the cover end closes;

[0037] At the same time, the second current limiting component 6 is also an umbrella-shaped structure. The handle end of the umbrella-shaped structure of the second current limiting component 6 is connected to the water inlet and outlet cover shell 2, and the cover end of the umbrella-shaped structure of the second current limiting component 6 covers the front end of the second flow hole 24. The cover end is also made of soft elastic material, such as rubber, silicone, etc. The cover end can intermittently block the second flow hole 24 under the drive of the water flow, so that the water flows through the second flow hole 24 into the water outlet space 22 and flows to the water outlet 12. When the cover end in the first current limiting component 5 is opened, the cover end in the second current limiting component 6 is closed. When the cover end in the first current limiting component 5 is closed, the cover end in the second current limiting component 6 is opened. When the suction cup component 3 is squeezed, the suction cup component 3 will be deformed to form suction on the water flow in the water inlet space 21. When the deformation is restored, a thrust is formed on the water flow in the water outlet space 22, completing the self-priming water supply action.

[0038] The suction cup assembly includes: a fixing seat 31, the front port of the fixing seat 31 is assembled and fixedly connected with the rear end of the water inlet and outlet housing 2; a multi-head suction cup 32 is installed on the fixing seat 31. In this embodiment, Figure 1-Figure 2The multi-head suction cup 32 is a five-head suction cup, which is composed of five groups of small suction cups distributed in a ring and connected. Five through holes are respectively provided on both sides of the fixed seat 31. The five groups of small suction cups in the two groups of multi-head suction cups 32 respectively pass through the five through holes on one side of the fixed seat 31. Each group of multi-head suction cups 32 corresponds to a water outlet 12. Each small suction cup on the multi-head suction cup 32 is connected with at least one first flow hole 23 and one second flow hole 24. A fixed support leg 321 is also provided at the rear end of the small suction cup. The fixed support leg 321 is connected to the drive assembly 4. The drive assembly 4 is used to provide power to the suction cup assembly 3 to squeeze the suction cup assembly 3 so that the five small suction cups in the multi-head suction cup 32 are deformed alternately to achieve continuous water inlet and outlet actions.

[0039] like Figure 1-Figure 4 As shown, the driving mechanism includes: a fixing member 41, which is detachably assembled and fixed to the rear end of the fixing seat 31; a motor 42, which is installed on the fixing member 41, and the number of the motors 42 is equal to the number of the water outlets 12 and the positions correspond one to one. Each group of motors 42 can independently drive each group of multi-head suction cups 32, thereby realizing separate control of different water outlets 12; an eccentric contraction pushing component, which is installed on the rotating shaft of each group of motors 42 and connected to the rear end of each group of small suction cups in the suction cup assembly 3, and is used to control after the motor 42 is started The five groups of small suction cups in the suction cup assembly 3 are deformed in an alternating manner, and the number of suction cup assemblies 3 is equal to the number of motors 42 and the positions correspond one to one; the eccentric contraction pushing assembly includes: a rotating member 43, which is fixed to the rotating shaft of the motor 42, and an oblique hole 431 is provided on the front end surface of the rotating member 43; an axle pin 44, which is inserted into the oblique hole 431; a transmission member 45, which is fixedly connected to the rotating member 43 through the axle pin 44, so that the movement trajectory of the transmission member 45 and the end of the axle pin 44 are the same, and the transmission member 45 is fixedly connected to the fixed support leg 321 set at the rear end of the suction cup;

[0040] Specifically, in the present embodiment, the rotation of the motor 42 shaft will synchronously drive the rotating member 43 to rotate, and at this time, the end of the shaft pin 44 obliquely inserted on the rotating member 43 away from the plug-in position will perform a circular motion, synchronously driving the transmission member 45 to perform a circular motion, because the transmission member 45 is fixedly connected to the five-head suction cup, that is, one end of the five groups of small suction cups in the five-head suction cup is restricted by the fixed seat 31, and the fixed legs 321 at the other end of the five groups of small suction cups are connected to the transmission member 45, and the five-head suction cup is made of compressible silicone or rubber material, as long as the motor 42 is turned on, under the drive of the transmission member 45, the five groups of small suction cups in the five-head suction cup will be staggered and continuously deformed and restored, thereby generating suction or thrust;

[0041] The transmission member 45 may be a five-pattern structure with five holes, and the five fixing legs 321 of the five-head suction cup are respectively inserted into the five holes for fixing.

[0042] Specifically, see again Figure 2The first flow hole 23 and the second flow hole 24 can be arranged on different planes of the water inlet and outlet housing 2, that is, the relative distance between the opening position of the first flow hole 23 and the suction cup assembly 3 is smaller than the relative distance between the opening position of the second flow hole 24 and the suction cup assembly 3, thereby providing more accommodation space for the water flow and improving the power.

[0043] Based on the first embodiment, Figure 2 As shown, the fixing member 41 is provided with a hanging ear 411, and the hanging ear 411 is used to fix the double pump as a whole.

[0044] Based on any of the above embodiments, Figure 2 As shown, the multi-head suction cup 32 forms a seal between the fixing member 41 and the water inlet and outlet housing 2 to prevent water from entering the driving assembly 4 and causing damage to the motor 42.

[0045] Based on any of the above embodiments, Figure 2 As shown, a sealing gasket 7 is provided between the top cover 1 and the water inlet and outlet housing 2 , so that both the water inlet space 21 and the water outlet space 22 can be sealed and assembled with the top cover 1 .
