Description

Technical Field

[0001] The utility model belongs to the technical field of dredges, and particularly relates to an air transmission device for dredges. Background Art

[0002] There are many ways to unclog household pipes, such as using steel wire, using dredging fluid, and using a high-pressure gas dredging device. The principle of this high-pressure gas dredging device is to pump air first. This process is similar to using an air pump to inflate a ball or bicycle wheel. The difference is that the dredging device stores the gas in the gas storage and transmission device of the dredging device itself. The current gas storage and transmission device has a two-layer structure. The first layer is used to store compressed gas, and the second layer is used to transport the compressed gas to the outside of the dredging device. There is a valve between the first and second layers. The valve cooperates with the firing device. After the firing device is fired by the user, the valve will connect the first and second layers, so that the compressed gas is transported from the second layer to the outside of the dredging device at one time, which is used to dredge the pipes and dredge the pipes through other pressures.

[0003] Some of these high-pressure air dredges require assembly for ease of transportation, with the main components connected primarily by threads. While the gas storage and transmission devices of these high-pressure air dredges can be disassembled, their general purpose is limited to clearing pipes and cannot be used for other purposes, such as inflating balls or bicycle tires.

[0024] In order to better understand the purpose, structure and function of this utility model, Figures 1 to 6 , the utility model is further described in detail about the gas transmission device for the dredge.

[0025] like Figure 1 and Figure 6 As shown, an air delivery device for a dredge according to an embodiment of the present invention includes an air delivery pipe head 100 , an air delivery pipe threaded portion 200 , an air delivery pipe middle portion 300 and an air delivery pipe bottom portion 400 .

[0026] In the present invention, the gas pipe head 100 is a circular tube, one end of which is fixedly connected to one end of the threaded portion 200 of the gas pipe. A first air inlet 110 is provided on the end of the gas pipe head 100, away from the threaded portion 200. When the clearing device is installed, the gas pipe head 100 lifts the rubber pad in the middle portion 300 of the gas pipe, allowing gas to enter the clearing device through the first air inlet 110.

[0027] The threaded portion 200 of the gas pipe is a circular tubular structure with an external thread provided on the outside. The end of the threaded portion 200 opposite the gas pipe head 100 is fixedly connected to the middle portion 300 of the gas pipe. The interior of the threaded portion 200 is connected to the interior of the middle portion 300. The middle portion 300 is a circular tubular structure with a first circular gas through-hole 310 provided on the outside. The end of the middle portion 300 away from the threaded portion 200 is fixedly connected to the gas pipe bottom 400, and the interior of the middle portion 300 is connected to the interior of the gas pipe bottom 400. A second gas through-hole 410 is provided in the middle of the end of the gas pipe bottom 400 away from the middle portion 300. The second gas through-hole 410 connects the interior and exterior of the gas pipe bottom 400.

[0028] When inflating items that require low air pressure, such as balloons and balls, you can use the second air supply hole 410 to inflate them with a handheld high-pressure air dredge. When inflating items that require higher air pressure, such as bicycle tires, you can use the first air supply hole 310 to inflate them. In this case, you can place the bottom of the air supply pipe 400 on the ground and inflate with both hands.

[0029] It can be understood that the outer diameter of the gas pipe head 100 is smaller than the inner diameter of the clearing device gas pipe 610, and the outer diameter of the gas pipe head 100 is smaller than the outer diameter of the gas pipe threaded portion 200; the gas pipe threaded portion 200 is used for threaded connection with the clearing device threaded connection portion 620; the outer diameter of the gas pipe threaded portion 200 is smaller than the outer diameter of the gas pipe middle portion 300, and the outer diameter of the gas pipe middle portion 300 is smaller than the outer diameter of the gas pipe bottom portion 400.

[0030] A second air inlet 120 is provided on the side of the gas pipe head 100, and the second air inlet 120 is used to connect the inside and outside of the gas pipe head 100. When inflating, gas can also enter the gas pipe head 100 through the second air inlet 120, thereby improving the efficiency of air intake.

[0031] A sealing ring 500 is also provided on the outside of one end where the gas pipe head 100 is fixedly connected to the gas pipe threaded portion 200. After using the sealing ring and installing the gas supply device for the clearing device, the air tightness of the entire clearing device can be further improved.

[0032] like Figure 3 and Figure 4 As shown, in some embodiments, the sealing ring 500 is fixedly connected to the gas pipe head 100 , and the sealing ring 500 is fixedly connected to the gas pipe threaded portion 200 .

[0033] The second gas supply hole 410 is a threaded hole that is also threadedly connected to a threaded plug 411. The end of the threaded plug 411 that faces the outside of the gas pipe bottom 400 is also provided with a bolt slot for securing a screwdriver to rotate the threaded plug 411. The provision of the screw hole enables the installation of a ball inflation needle, most of which are connected via threads, into the second gas supply hole 410. When the second gas supply hole 410 is not used and only the first gas supply hole 310 is used, the threaded plug 411 can be installed, and inflation can be performed only through the first gas supply hole 310.

[0034] A middle plug 311 is provided in the first gas transmission hole 310, and the middle plug 311 is detachably connected to the first gas transmission hole 310. When the first gas transmission hole 310 is not used and only the second gas transmission hole 410 is used, the middle plug 311 can be installed and air can be pumped only through the second gas transmission hole 410.

[0035] The threaded connection part 620 of the dredge is fixedly connected to the dredge gas pipe 610 , and the threaded connection part 620 of the dredge is arranged inside the middle section 600 of the dredge.

[0036] The middle section 600 of the clearing tool has a connecting cavity 630. After the air pipe threaded portion 200 is threadedly connected to the clearing tool's threaded connection portion 620, the end of the air pipe head 100, away from the bottom of the air pipe threaded portion 200, is accommodated in the connecting cavity 630. The end of the middle section 600 of the clearing tool opposite the threaded connection portion 620 is also connected to the clearing tool's air pump assembly.

[0037] In the present invention, the dredge aeration assembly includes a dredge aeration pipe 710, which is connected to the dredge middle section 600. An aeration hole is provided at one end of the dredge aeration pipe 710 connected to the dredge middle section 600, and the aeration hole is communicated with the connecting cavity 630. A compression aeration unit 720 is also provided on the side of the dredge aeration assembly away from the dredge middle section 600. One end of the compression aeration unit 720 is disposed inside the dredge aeration pipe 710, and the compression aeration unit 720 is slidably connected to the dredge aeration pipe 710.

[0038] During use, after removing the gas storage and delivery device threaded onto the threaded connection 620 of the dredge, the dredge gas delivery device is installed. By threading the gas delivery pipe threaded portion 200 into the dredge threaded connection 620, the dredge gas delivery device is mounted onto the dredge midsection 600. At this point, the gas delivery pipe head 100 extends into the connecting cavity 630 of the dredge midsection 600. Furthermore, the dredge gas delivery pipe 710 in the dredge gas delivery assembly is also connected to the connecting cavity 630, allowing gas pumped from the dredge gas delivery assembly to directly enter the dredge gas delivery device. The air supply device for the clearing tool is hollow inside and no other air storage layer is set. After the air pumped by the clearing tool's inflation component enters the air supply device for the clearing tool from the air supply pipe head 100, it enters the object to be inflated through the first air supply hole 310 and / or the second air supply hole 410. It does not involve a one-time inflation after firing. This process is consistent with using an air pump to inflate the object to be inflated, and will not cause damage to the object to be inflated due to the excessive pressure of the one-time input gas.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
