Description

Technical Field

[0001] This utility model relates to fumigation equipment, specifically to a fumigation anti-spray mechanism and a fumigation device. Background Technology

[0002] The microcatheter used in interventional surgery is made by shaping needles. Specifically, a metal wire is bent into a set shape by hand or equipment to form a shaping needle. Then, the microcatheter is inserted into the shaping needle. By heating the microcatheter, the microcatheter shrinks and is shaped.

[0003] Existing heating equipment (fumigators) often cause water to spray out after boiling, splashing onto the outside of the equipment or even scalding the operators. Utility Model Content

[0004] This utility model addresses the above-mentioned problems by proposing an anti-spray mechanism for a fumigation device and a fumigation device in general.

[0005] The technical solution adopted by this utility model is as follows:

[0006] A blowout preventer mechanism for a fumigator includes a blowout preventer shell, a baffle, and a nozzle;

[0007] The upper part of the blowout preventer has a steam outlet, the lower part of the blowout preventer has a steam inlet, and the nozzle is disposed at the steam outlet;

[0008] The blowout preventer has a first sidewall and a second sidewall arranged opposite to each other. The first sidewall and the second sidewall are alternately provided with baffles, and a bent channel for steam to pass through is formed between the baffles. The steam inlet is located below the lowermost baffle.

[0009] The alternating baffles on the first and second side walls create a zigzag channel that effectively blocks water entering the steam inlet along with the steam, preventing it from entering the steam outlet. The anti-spray mechanism of this application effectively prevents high-temperature water from being ejected from the nozzle.

[0010] In one embodiment of the present invention, one end of the baffle is fixed to the blowout shield, and the other end is inclined downward.

[0011] The non-fixed end of the baffle is tilted downwards, which allows the water condensed above the baffle to drip down under gravity and eventually collect on the bottom wall of the blowout shield.

[0012] In one embodiment of the present invention, the first and second sidewalls of the blowout preventer are each provided with mounting holes, and the baffle is fixed inside the blowout preventer by fasteners passing through the mounting holes from the outside, and the mounting holes are filled with sealant.

[0013] This structure facilitates the installation of the baffle, and the sealing effect of the blowout shield sidewalls can be ensured by filling the mounting holes with sealant.

[0014] In one embodiment of the present invention, the steam inlet is located on the second side wall, and the lowest baffle is fixed to the first side wall.

[0015] When the bottom baffle is fixed to the second side wall (creating a gap between the baffle and the first side wall), the water entering the steam inlet will spray onto the first side wall and then easily flow upward through the gap between the bottom baffle and the first side wall, resulting in poor splash prevention. However, when the bottom baffle is fixed to the first side wall, the water entering the steam inlet will spray onto the first side wall, and the upward splashing water will be blocked to a greater extent by the bottom baffle, resulting in better splash prevention.

[0016] In one embodiment of this utility model, the nozzle is a bent nozzle, and the nozzle is rotatably installed at the steam outlet.

[0017] The nozzle is a bent nozzle that is rotated and installed at the steam outlet. This allows the operator to adjust the angle of the nozzle as needed, so that steam can be sprayed out from different directions, making the operation more flexible.

[0018] In one embodiment of the present invention, at least one sealing ring is provided between the nozzle and the steam outlet.

[0019] Setting a sealing ring ensures a reliable seal between the nozzle and the steam outlet.

[0020] In one embodiment of the present invention, a temperature sensor is also included, which is mounted on the blowout preventer and the sensing part of the temperature sensor extends into the blowout preventer.

[0021] In one embodiment of the present invention, the sensing part of the temperature sensor is located at the steam outlet.

[0022] In one embodiment of the present invention, the bottom wall of the blowout shield has a liquid return port.

[0023] The blocked water and the water that condenses and falls back from the steam will all gather at the bottom wall of the blowout preventer. By setting a liquid return port, the water can be allowed to flow out, ensuring that the blowout preventer can work reliably.

[0024] In practical applications, the fumigator also includes a water supply tank. The liquid return port is connected to the water supply tank, allowing the water inside the anti-spray shell to flow back to the water supply tank for reuse.

[0025] This application also discloses a fumigator, including the anti-spray mechanism of the fumigator described above.

[0026] In one embodiment of the present invention, the fumigator further includes a frame, an anti-spray mechanism is disposed on the frame, and the frame is equipped with at least one detection sensor in the area around the nozzle, the detection sensor being used to detect the operator's hand.

[0027] The detection sensor can be of various types, such as diffuse reflection sensors and laser sensors. When an object is within the detection range of the sensor, it can be detected. By detecting the presence of a hand, the fumigation device can achieve various control methods, such as stopping directly or stopping after a set delay if no hand is detected.

[0028] The beneficial effects of this invention are as follows: the baffles alternately arranged on the first and second side walls form a bent channel, which effectively blocks water entering the steam inlet along with steam, preventing water from entering the steam outlet. The anti-spray mechanism of this application effectively prevents high-temperature water from spraying out of the nozzle. Attached Figure Description

[0046] The present invention will now be described in detail with reference to the accompanying drawings.

[0047] Example 1

[0048] like Figures 1-6 As shown, this embodiment discloses a fumigator, which includes a spray preventer 4. As... Figure 1 , 2 As shown in Figures 3 and 4, the blowout preventer 4 of this embodiment includes a blowout preventer shell 42, a baffle 43, and a nozzle 41 for steam ejection.

[0049] The upper part of the blowout preventer 42 has a steam outlet 42a, the lower part of the blowout preventer 42 has a steam inlet 42b, and the nozzle 41 is disposed at the steam outlet 42a.

[0050] The blowout preventer 42 has a first sidewall 421 and a second sidewall 422 arranged opposite to each other. Baffles 43 are alternately arranged on the first sidewall 421 and the second sidewall 422, forming a bent channel 42c for steam to pass through between the baffles 43. The steam inlet 42b is located below the lowermost baffle 43. One end of the second pipe 53 is connected to the steam inlet 42b of the blowout preventer 42, and the other end is connected to the steam exhaust port 32 of the steam heating assembly 3.

[0051] like Figure 2 and 4 As shown, in this embodiment, one end of the baffle 43 is fixed to the blowout shield 42, and the other end is inclined downward.

[0052] The non-fixed end of the baffle 43 is tilted downwards, which allows the water condensed above the baffle 43 to drip down under the action of gravity and eventually collect on the bottom wall of the blowout shield 42.

[0053] like Figure 3 As shown, in one embodiment of the present invention, the first sidewall 421 and the second sidewall 422 of the blowout preventer 42 both have mounting holes 423, and the baffle 43 is fixed inside the blowout preventer 42 by fasteners passing through the mounting holes 423 from the outside. The mounting holes 423 are filled with sealant.

[0054] This structure facilitates the installation of the baffle 43, and the sealing effect of the sidewall of the blowout shield 42 can be ensured by filling the mounting hole 423 with sealant.

[0055] like Figure 2 As shown, in this embodiment, the steam inlet 42b is located on the second side wall 422, and the lowest baffle 43 is fixed to the first side wall 421.

[0056] When the lowermost baffle 43 is fixed to the second side wall 422 (forming a gap between the baffle 43 and the first side wall 421), the water just entering the steam inlet 42b will spray onto the first side wall 421 and then easily pass upward through the gap between the lowermost baffle 43 and the first side wall 421, resulting in poor splash prevention. However, when the lowermost baffle 43 is fixed to the first side wall 421, the water just entering the steam inlet 42b will spray onto the first side wall 421, and the upward splashing water can be blocked to a greater extent by the lowermost baffle 43, resulting in better splash prevention.

[0057] like Figure 2 As shown, in this embodiment, the nozzle 41 is a bent nozzle 41, and the nozzle 41 is rotatably installed at the steam outlet 42a.

[0058] The nozzle 41 is a bent nozzle 41 and is rotatably installed at the steam outlet 42a. This allows the operator to adjust the angle of the nozzle 41 as needed, thereby enabling steam to be ejected from different directions, making the operation more flexible.

[0059] like Figure 2 As shown, in this embodiment, at least one sealing ring 44 is provided between the nozzle 41 and the steam outlet 42a. The sealing ring 44 ensures a reliable seal between the nozzle 41 and the steam outlet 42a.

[0060] like Figure 3 As shown, in this embodiment, a temperature sensor 45 is also included, which is mounted on the blowout preventer 42 and whose sensing part extends into the steam outlet 42a.

[0061] like Figure 2 , 3 As shown in Figure 4, the fumigator also includes:

[0062] Rack 1;

[0063] Water supply kettle 2 is detachably mounted on frame 1;

[0064] Steam heating component 3 is installed on frame 1. Steam heating component 3 has water inlet 31 and steam outlet 32. Water inlet 31 is connected to water supply kettle 2 through first pipe 51.

[0065] A water pump 52 is installed on the first pipeline 51 and is used to transport water from the water supply kettle 2 to the steam heating assembly 3.

[0066] In this embodiment, the blowout preventer 4 is mounted on the frame 1, and the steam exhaust port 32 of the steam heating component 3 is connected to the blowout preventer 4 through the second pipe 53.

[0067] In this application, the steam and water coming out of the steam outlet 32 ​​of the steam heating component 3 are not sprayed out directly, but enter the anti-spray mechanism 4 and are finally sprayed out through the nozzle 41 of the anti-spray mechanism 4. By setting an additional anti-spray mechanism, high-temperature water can be prevented from spraying out of the nozzle 41.

[0068] In practical applications, the steam heating component 3 is an existing component, which can be a steam generator or a small boiler, etc. It typically includes a water storage space for holding water and a heating element for processing the water in the water storage space.

[0069] In practical applications, the steam heating component 3 is covered with a heat insulation layer.

[0070] In this embodiment, the bottom wall of the blowout shield 42 has a liquid return port (not shown in the figure), and the frame 1 has a return hole 11 communicating with the water supply tank 2 (see figure). Figure 4 The liquid return port corresponds to the return hole 11, and the water in the anti-spray shell 42 can flow back to the water supply kettle 2 through the liquid return port and the return hole 11.

[0071] like Figure 1 The steam generator also includes a controller 6 mounted on the frame 1. The steam heating component 3, the water pump 52, and the temperature sensor 45 are all electrically connected to the controller 6. The controller 6 also has a display unit and a sound unit.

[0072] The temperature sensor in this application is used to detect the steam temperature at the fumigation port, thereby determining whether fumigation of the microcatheter can be performed.

[0073] In practical applications, the controller 6 can achieve various forms of control or prompts through the display unit and the sound unit. For example, the sound unit can realize voice control. When the temperature measured by the temperature sensor 45 is greater than the set value, the display unit will work to perform a countdown operation, which will facilitate more standardized operation by the operator and ensure the steaming time.

[0074] like Figure 6 In this embodiment, a control element 62 is also included. The control element 62 is a remote control or a footpad, and it is connected to the controller 6 via a control line or a wireless communication module. The control element 62 enables convenient control operations.

[0075] like Figure 2 and 5 As shown, in this embodiment, the frame 1 has a circuit board 12 and a receiving slot 13, and the controller 6 is detachably mounted on the receiving slot 13. The controller 6 has a connector 61 that is connected to the circuit board 12.

[0076] Example 2

[0077] like Figures 7-11As shown, the difference between this embodiment and Embodiment 1 is that it also includes a shaping needle rotating mechanism 7, which includes:

[0078] The mounting base 71 is fixed to the frame 1;

[0079] The movable seat 72 is magnetically attracted to the fixed seat 71, and the movable seat 72 can be moved off the fixed seat 71.

[0080] The work box 73 is mounted on the movable base 72. The work box 73 has a rotatable rotating part 731, a motor (not shown in the figure) that drives the rotating part 731 to rotate, and a battery that powers the motor. The rotating part 731 has a hollow insert 732 for the end of the shaping needle 8 to be inserted.

[0081] When the fumigator is working, the end of the shaping needle 8, which is equipped with a micro-conduit 9, is inserted into the hollow insert 732. The motor drives the rotating part 731, the hollow insert 732 and the shaping needle 8 to rotate synchronously, and adjusts the angle of the nozzle 41 so that the steam sprayed from the nozzle 41 is blown towards the area where the micro-conduit 9 is located.

[0082] The movable seat 72 and the fixed seat 71 are magnetically attracted to each other, so that the movable seat 72 can be moved out as a whole. Continuous operation can be achieved by replacing the movable seat 72. This can prevent the operator from being sprayed with steam when the shaping needle 8 is pulled out directly on the steamer.

[0083] The magnetic attraction between the movable seat 72 and the fixed seat 71 means that magnets are respectively provided between the fixed seat 71 and the movable seat 72, or one of them has a magnet and the other has iron.

[0084] In practical applications, the shaping needle 8 and the hollow insert 732 are either interference-fitted or clearance-fitted. In addition, an elastic layer can be provided inside the hollow insert 732 to reliably confine the shaping needle 8 inserted into the hollow insert 732.

[0085] This application, by setting a molding needle 8 installation mechanism, can drive the molding needle 8, which is threaded with a microcatheter 9, to rotate, so that the microcatheter 9 can come into more comprehensive and uniform contact with steam.

[0086] like Figures 7-11 As shown, in this embodiment, the movable seat 72 has a lifting adjustment assembly, and the working box 73 is fixed to the upper end of the lifting adjustment assembly. The lifting adjustment assembly includes two tubular parts 721 that are slidably connected to each other. The two tubular parts 721 can rotate relative to each other and move up and down. The end of the tubular part 721 with a larger outer diameter is screwed with a locking bolt 722. The locking bolt 722 is used to press against the outer wall of the tubular part 721 with a smaller outer diameter, so that the two tubular parts 721 are fixed relative to each other.

[0087] This structural form of the lifting and adjusting component can not only adjust the height of the working box 73 up and down, but also adjust the angle of the working box 73, so as to better cooperate with the rotating nozzle 41. The heating and shaping operation of the micro-conduit 9 is simple and reliable.

[0088] like Figure 11 As shown, in this embodiment, the fixed base 71 includes a horizontal part 711 and a vertical part 712. The horizontal part 711 is fixed to the upper surface of the frame 1, and the vertical part 712 abuts against the side wall of the frame. The horizontal part 711 has a positioning groove 7111, and the bottom of the movable base 72 is embedded in the positioning groove 7111.

[0089] Example 3

[0090] like Figure 12 As shown, the difference between this embodiment and embodiment 1 is that: at least one detection sensor 14 is installed on the frame 1 around the nozzle 41, and the detection sensor 14 is used to detect the operator's hand.

[0091] The detection sensor 14 can be of various types, such as a diffuse reflection sensor, a laser sensor (TOF050F - TOF laser rangefinder sensor), etc. When an object is within the detection range of the detection sensor 14, the detection sensor 14 can detect it. By detecting whether there is a hand, the fumigator can achieve various control modes. For example, when no hand is detected, it can stop directly or stop working after a set time (the steam heating component 3 stops heating).

[0092] Preferably, multiple detection sensors 14 can be arranged at intervals around the nozzle 41.

[0093] The above description is only a preferred embodiment of the present utility model and does not limit the scope of patent protection of the present utility model. Any equivalent structural transformations made based on the content of the present utility model specification and drawings, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present utility model.
