Description

Technical Field

[0001] The present application relates to the field of stage effect equipment, and in particular to a water pump for a fog machine. Background Art

[0002] In recent years, as people's requirements for stage facilities have become higher and higher, stage lighting has developed towards high-tech and high-specification lamps, and the demand for stage smoke is also indispensable. Smoke can refract the light beams emitted by stage lights, set off the performance atmosphere, and enhance the audience's visual effects. Therefore, smoke machines have become an indispensable item in stage equipment. At present, the scope of use of smoke machines is getting wider and wider. Not only stage performances, but also wedding venues, celebrations, and entertainment venues often see smoke machines.

[0003] Smoke machines are divided into dry ice smoke machines and liquid nitrogen smoke machines. Both of these smoke machines can produce a large amount of smoke in a short time by contacting dry ice or liquid nitrogen with water. Because smoke machines are generally single-molded machines (roughly regular in shape as a whole), and the existing smoke machines use water pumps to suck water from the water tank through the water inlet of the water pump and then spray it on the dry ice or liquid nitrogen through the water outlet of the water pump, and two through holes need to be opened on the water tank to install the water inlet and outlet of the water pump, and the water pump needs to be installed outside the water tank for waterproofing reasons. Therefore, in order to accommodate the appearance of water pumps on the market, the smoke machine box needs to be designed as an irregular body. First, it is inconvenient for designers to design drawings, and second, it is inconvenient for processing personnel to process, and the efficiency is very low. Utility Model Content

[0004] In order to effectively solve the problem of low efficiency in the design and processing of existing fog machines, the present application provides a water pump for a fog machine.

[0005] The water pump for a fog machine provided in this application adopts the following technical solution:

[0006] A water pump for a fog machine, comprising a driver, a water seal, a center plate, a propeller, a guide cover, and a water outlet pipe;

[0007] The central disk is provided with a through hole, the water seal is installed in the through hole, the output end of the driver passes through the through hole, and the central disk is installed on the driver;

[0008] The propeller fixing sleeve is arranged on the output end of the driver after passing through the through hole;

[0009] The lower end of the deflector is mounted on the central disk;

[0010] The lower end of the water outlet pipe is installed on the upper end of the deflector cover.

[0011] By adopting the above technical solution, all parts except the motor body are arranged in the water tank of the smoke machine, and the output end of the driver is used to cooperate with the propeller and the air deflector to replace the water absorption of the water pump in the prior art. In detail, the output end of the driver is used to drive the propeller, and then stir the water in the water tank to enter the air deflector in a rotating form, and then the water enters the water outlet pipe in a direct current form after passing through the air deflector, and then the water is sprayed from the water outlet pipe and falls into the smoke machine box filled with dry ice or liquid nitrogen to generate smoke. The smoke machine using the water pump does not need to accommodate the appearance of the water pump sold on the market during design drawings and processing and manufacturing, that is, the smoke machine can be designed as a regular body as a whole, and it is also very convenient and efficient during processing and manufacturing.

[0012] In order to better implement the present application, the following configuration structure is particularly adopted: the driver is a DC motor.

[0013] By adopting the above technical solution, the DC motor can be controlled by 512 signals, which is efficient and convenient; at the same time, it can have its own power supply, that is, it does not need to be plugged in, and can be used with a lithium battery.

[0014] In order to better realize the present application, the following setting structure is particularly adopted: it also includes a water seal baffle, which is sleeved on the output end of the driver, and the water seal baffle is installed between the driver and the water seal and abuts against the water seal.

[0015] By adopting the above technical solution, the water seal is firmly installed in the through hole on the central disk to prevent water leakage.

[0016] In order to better realize the present application, the following setting structure is particularly adopted: it also includes a first sealing ring, and the lower end of the deflector, the center plate, and the first sealing ring are fixedly connected together.

[0017] By adopting the above technical solution, when the water pump is used in the water tank of the smoke machine, since the center disk and the components above it are immersed in water, in order to achieve a better sealing effect, that is, to prevent the water in the water tank of the smoke machine from flowing into the space where the driver is located from between the lower surface of the center disk and the upper surface of the bottom of the water tank, a first sealing ring is installed between the center disk and the upper surface of the bottom of the water tank.

[0018] In order to better realize the present application, the following configuration structure is particularly adopted: the water outlet pipe is provided with a through hole in its radial direction.

[0019] By adopting the above technical solution, water can flow out from the water outlet pipe without having to flow to the top of the water outlet pipe.

[0020] In order to better realize the present application, the following setting structure is particularly adopted: it also includes a second sealing ring, and the second sealing ring is installed between the lower end of the water outlet pipe and the upper end of the deflector cover.

[0021] By adopting the above technical solution, the seal is further improved to prevent water from overflowing due to a gap between the outlet pipe and the guide cover. Because the driver generates water pressure when working, if there is a gap between the outlet pipe and the guide cover and water overflows, the water pressure will be reduced, which will affect the water discharge of the outlet pipe.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The output end of the driver is used in conjunction with the propeller and the air deflector to replace the water suction of the water pump in the prior art. That is, the output end of the driver is used to drive the propeller, and then stir the water in the water tank to enter the air deflector in a rotating form, and then the water passes through the air deflector and enters the water outlet pipe in a direct flow form, and then the water is sprayed from the water outlet pipe and falls into the smoke machine box filled with dry ice or liquid nitrogen to generate smoke. Therefore, the smoke machine using this water pump does not need to accommodate the appearance of the water pump sold on the market during design drawings and processing and manufacturing, that is, the smoke machine can be designed as a regular body as a whole, which is also very convenient and efficient during processing and manufacturing;

[0024] 2. By using the DC motor as a driver, the DC motor can be controlled by a 512 signal, which is efficient and convenient; at the same time, it can have its own power supply, that is, it does not need to be plugged in, and can be used with a lithium battery, which also serves the purpose of convenient use;

[0025] 3. By setting the first sealing ring and the second sealing ring, the sealing effect of the water pump is better and the service life is longer;

[0026] 4. The overall structure is cleverly designed, easy to operate and inexpensive. BRIEF DESCRIPTION OF THE DRAWINGS

After the second screws 52 are tightened, they are recessed into the lower bottom surface of the center disk 5. Two guide plates 71 are fixedly installed in the hollow part of the upper half of the air deflector 7. The guide plate 71 is a curved surface as a whole, the lower half is bent, and the upper half is parallel to the axis of the air deflector 7. The propeller 6 is arranged below the guide plate 71, the first sealing ring 2 is tightly sleeved on the upper end of the DC motor, the lower end of the air deflector 7, the center disk 5, and the first sealing ring 2 are connected together by screws, and the water outlet pipe 9 is provided with a plurality of through holes in its radial direction for water to be sprayed out.

[0037] The implementation method of a water pump for a fog machine in the embodiment of the present application is as follows: Figure 1-Figure 6First, install the first sealing ring 2, the DC motor, the water seal baffle 3, the water seal 4, the center disk 5, the propeller 6, the deflector 7, the second sealing ring 8, and the water outlet pipe 9 in sequence, then open a through hole on the bottom surface of the water tank 10 of the fog machine, put the output shaft of the DC motor upward and the other end of the DC motor downward into the through hole on the bottom surface of the water tank 10, and the lower end of the deflector 7, the center disk 5, and the first sealing ring 2 are provided with corresponding threaded holes (the threaded holes are alternately arranged with the second screws 52), and corresponding threaded holes are opened around the through hole on the bottom surface of the water tank 10, and finally the lower end of the deflector 7, the center disk 5, the first sealing ring 2, and the bottom surface of the water tank 10 are fixedly connected together with screws.
