Description

Technical Field

[0001] This application relates to a spraying device, and more particularly to a spraying device for cleaning gelatinous sludge from pipes. Background Technology

[0002] To couple energy or protect local human tissue, medical aesthetic devices require consumables containing adhesive coupling agents. For example, cryolipolysis devices use protective films rich in antifreeze gel. During treatment, this highly viscous gel can enter the vacuum tubing of the device through compression or vacuum adsorption, potentially causing blockages. The rear end of the tubing is usually connected to electrical components, such as a negative pressure suction pump. If not handled properly, the gel can be further drawn into the negative pressure pump, potentially damaging it. Common methods to protect the pump include adding a breathable but waterproof filter at the front of the tubing, adding an external or internal gas-liquid separator, or suspending the tubing inverted to allow the gel to flow out naturally. However, each method has its drawbacks. First, high-density filters can cause airway blockage when there is a significant amount of gel buildup, resulting in a sharp decrease in negative pressure flow. Insufficient pressure can reduce treatment effectiveness or even cause the device to detach from the patient. To combat blockages, manufacturers often increase the output of the pressure pump, but excessive pressure can cause patient discomfort. Secondly, external gas-liquid separators affect the equipment's appearance, while internal ones are inconvenient to replace. Most importantly, if the gas-liquid separator is not emptied promptly, the gel inside the tubing can deteriorate and contaminate the pipes, posing a risk of entering the pump. Finally, the gel's high viscosity means that inverting the tubing to empty it doesn't completely remove it, leaving residue that can deteriorate, contaminate or block the tubing, and eventually enter the pump.

[0025] The following is a detailed description of the spraying device for cleaning gelatinous substances in pipes according to this application, with reference to the accompanying drawings.

[0026] The spraying device of this application for cleaning gelatinous dirt in pipes includes: a tube insertion component 10 and a fluid source connection cover 20.

[0027] The cannulation component 10 includes an inner tube 11, an outer tube 12, and a tip 14.

[0028] The inner tube 11 is housed within the outer tube 12, with the upper end of the inner tube 11 extending beyond the upper end of the outer tube 12; the internal space of the inner tube 11 constitutes a first fluid space; a predetermined interval is formed between the inner tube 11 and the outer tube 12, which constitutes a second fluid space.

[0029] A tip 14 is formed at the lower part of the cannulation member 10, located below the inner tube 11 and the outer tube 12. The upper end face of the tip 14 is integrally connected to the lower end of the inner tube 11 via a connector 13. An annular gap 15 is formed between the upper end face 14a of the tip 14 and the lower end of the outer tube 12. A plurality of notches 13a are formed around the circumferential surface of the connector 13; each notch 13a passes through the connector 13 in the vertical direction; through these notches 13a, the annular gap 15 communicates with the first fluid space. Figure 6 The connectors in the middle are cross-shaped when viewed from above, but they can also be star-shaped or Y-shaped.

[0030] N layers of channels 12a, penetrating the wall of the outer tube 12, are formed around the lower part of the outer tube 12. These channels 12a communicate with the second fluid space. Each layer of channels 12a includes M channels 12a; the attached diagram shows six layers, which are only used to illustrate the basic structure of the invention and are not intended to limit the number of channel layers. Each layer of channels is formed on the same plane perpendicular to the axis of the outer tube 12, and the M channels 12a in the same layer are evenly distributed along the circumference of the outer tube. N is a natural number greater than 2; M is a natural number greater than 4. In principle, the larger M is, the more uniform the jet of the second fluid is. The specific value of M is related to the diameter of the channel.

[0031] A fluid source connection cap 20 is installed on the upper end of the cannulation component 10; a first fluid connector 24 and a second fluid connector 25 are formed on the fluid source connection cap 20; the first fluid source connector 24 is used to connect to a first fluid source, and the second fluid source connector 25 is used to connect to a second fluid source; the internal space of the fluid source connection cap 20 forms an inner tube connection portion 21 and an outer tube connection portion 22, such as... Figure 9 As shown. The upper end of the inner tube 11 of the cannulation component 10 is airtightly installed in the inner tube connection part 21, and the upper end of the outer tube 12 of the cannulation component 10 is airtightly installed in the outer tube connection part 22.

[0032] like Figure 12 As shown, the tip 14 is used to pierce through the gelatinous dirt 50 after being inserted into the pipe 40, so that the orifice 12a and the annular gap 15 are located below the gelatinous dirt 50; the first fluid F1 enters the fluid source connection cover 20 through the first fluid source connector 24 and then enters the first fluid space through the upper end of the inner tube 11. After flowing through multiple notches 13a, it is ejected from the annular gap 15 and sprayed onto the inner wall of the pipe 40. The ejected first fluid F1 forms a baffle in the pipe; the second fluid F2 enters the fluid source connection cover 20 through the second fluid source connector 25 and then enters the second fluid space through the upper end of the outer tube 12. It is then ejected through the orifice 12a and enters the pipe 40. After being blocked by the baffle formed by the first fluid, it flows upward, thereby pushing the gelatinous dirt 50 located above the orifice 12a upward and discharging it.

[0033] The channel 12a is formed at an angle, so that the jet formed after the second fluid is ejected from the channel via F2 is an upward-sloping jet, such as... Figure 12 As shown.

[0034] The multi-layered channel 12a is divided into L sections at the bottom of the outer tube, where L is a natural number greater than 2; the channels 12a of adjacent layers in each section are axially aligned with each other; the channels 12a of different sections do not overlap when viewed axially. Figure 5 The structure is divided into three sections, each containing two layers of channels.

[0035] The shift sleeve 30 is rotatably fitted onto the outer tube 12. For example... Figure 11 As shown, M rows of through holes 30a are formed around the lower part of the shift sleeve 30, and these M rows of through holes 30a are evenly distributed on the circumferential surface of the shift sleeve 30. Each row of through holes includes N through holes, and these N through holes are formed in a straight line in the axial direction. When the through hole 30a is directly opposite the channel 12a, the outlet of the channel 12a is completely located within the through hole 30 and is not obstructed by the shift sleeve 30.

[0036] By rotating the shift sleeve 30, its through-hole 30a is aligned directly with the channel 12a in only one of the L zones. The channels in the other L zones are completely blocked by the shift sleeve, thus selecting only the channel in the corresponding zone to form the jet of the second fluid. The purpose of this arrangement is mainly to consider that as the gelatinous dirt moves upward, the impact of the jet ejected from the lower channel will be greatly reduced. Therefore, the shift sleeve is used to block the channel located at a relatively far position, and only the jet ejected from the closer channel with better efficiency is used. Thus, the channels are released in sections, allowing the pressure of the second fluid jet to be utilized efficiently.

[0037] A shift sleeve connection portion 23 is formed in the receiving space of the fluid source connection cover 20, and the upper part of the shift sleeve 30 is rotatably installed in the shift sleeve connection portion 23.

[0038] An annular groove 23a is formed on the shift sleeve connecting part 23; an annular protrusion 31 is formed along the outer periphery of the upper end of the shift sleeve 30; the annular protrusion 31 is rotatably installed in the annular groove 23a. The annular protrusion 31 and the groove 23a are mainly for fixing the shift sleeve 30 axially, and the main purpose is to ensure that the through hole 30a and the corresponding layer's channel 12a are located on the same plane and will not be misaligned in the vertical direction. L marking lines can also be provided on the outer peripheral surface of the shift sleeve, and one marking line is provided on the outer surface of the fluid source connection cover 20; when the shift sleeve exposes the channels of different zones, the different marking lines among the L marking lines are aligned with the marking line of the fluid source connection cover, thereby helping to determine which zone is currently working.

[0039] The upper end face 14a of the tip 14 is formed as a downwardly concave curved surface, which makes the first fluid tend to be ejected upward, thus providing a more powerful barrier for the second fluid.

[0040] Preferably, the first fluid is water; the second fluid is air.

[0041] When using, such as Figure 12 As shown, the tip is pierced through the gelatinous substance. Since the gelatinous substance is usually stuck not far from the pipe inlet, it is usually easy to determine whether the tip has successfully pierced through. First, a first fluid is introduced, which forms a baffle after being ejected from the annular gap. The first fluid is water, and the second fluid is air. The density of the first fluid is much greater than that of the second fluid, which helps the baffle form a barrier against the second fluid. Then, the second fluid is introduced. At this time, the lowest channel is selected by rotating the shift sleeve. After the second fluid is ejected through the lowest channel for a certain period of time, the shift sleeve is rotated to select channels layer by layer upwards. In this way, the second fluid changes layer by layer from bottom to top in numerical order, always maintaining a strong push against the gelatinous substance, until finally the gelatinous substance is pushed out.
