Description

Technical Field

[0001] This utility model relates to the field of fumigation therapy, specifically to a fumigation machine condensate collection device. Background Technology

[0002] A fumigation machine, based on Traditional Chinese Medicine (TCM) theory, combines Chinese herbal medicine with a fumigation device to generate and deliver hot medicinal steam. This allows the skin to absorb the medicine through the combined effects of heat and medicinal properties. Clinically, it is commonly used as an adjunct treatment for diseases in surgery, dermatology, gynecology, physiotherapy, and proctology. The fumigation machine mainly consists of a medicine tank, inlet / outlet pipes, a heating device, temperature / level control units, a display unit, and a treatment head, and is used for localized fumigation therapy on the human body.

[0003] During normal treatment, the fumigation machine sprays out high-temperature medicinal mist. Due to the physical properties of steam, condensation water will accumulate at the end of the spray nozzle of the fumigation machine. The dripping of high-temperature condensation water can cause accidental burns to the patient's treatment area. Summary of the Invention

[0004] To address the problem that condensate tends to accumulate at the nozzle of a fumigation machine due to the physical properties of steam, and that dripping hot condensate can cause accidental burns to the treatment area, this invention proposes a condensate collection device for fumigation machines. When the hot steam carrying condensate is ejected from the exhaust pipe and passes through a metal filter, a gas-liquid separation process occurs. The condensate is then further guided to a sponge for collection, reducing the risk of burns caused by dripping hot condensate.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A condensate collection device for a fumigation machine includes a fixed cover and a nozzle cover positioned in front of the fixed cover. A nozzle assembly, including an exhaust pipe, is housed inside the fixed cover. Several ventilation holes are formed on the side wall of the nozzle cover. A retaining ring is provided at the connection between the nozzle cover and the fixed cover. One end of the exhaust pipe passes through the fixed cover and the retaining ring and extends into the nozzle cover. A guide vane is provided on one side of the retaining ring, and a metal filter screen is installed inside the guide vane. A gap exists between the side of the metal filter screen and the end face of the exhaust pipe extending into the nozzle cover. A protrusion is provided on one side of the guide vane, with notches at both its upper and lower ends. When high-temperature steam carrying condensate is ejected from the exhaust pipe and passes through the metal filter screen, a gas-liquid separation process occurs.

[0007] Furthermore, the fixing ring includes an inner ring and an outer ring, which are coaxially connected. A through hole is provided at the center of the inner ring for the air outlet pipe to pass through. After passing through the through hole in the fixing ring, the air outlet pipe faces the metal filter screen.

[0008] Furthermore, the nozzle cover is a conical cover with openings at both ends. The small end of the nozzle cover is connected to the outer ring by a screw, and the large end of the nozzle cover is provided with an annular flow guide. A sponge is placed inside the flow guide, and an annular groove is opened on one side of the flow guide. Several flow guide holes are opened through the groove. The flow guide holes are evenly distributed in the groove of the flow guide.

[0009] Furthermore, the guide vane and the fixing ring are connected by screws, and the protrusion on the guide vane is fitted to the fixing ring.

[0010] Furthermore, one end of the fixing cover is open and the other end is closed, and the closed end of the fixing cover is connected to the outer ring by screws in three phases.

[0011] Furthermore, the nozzle assembly also includes a housing fixed to the closed end of the fixed cover. The air outlet pipe is horizontally positioned at the left end of the housing, and its right end penetrates the left side of the housing and extends into the housing. A vertically positioned air inlet pipe is connected to the lower end of the housing, and its upper end penetrates the bottom surface of the housing and extends into the housing, with the upper end of the air inlet pipe being higher than the air outlet pipe. A drain pipe connected to the interior of the housing is provided on the bottom surface of the housing, with its upper end flush with the bottom surface of the housing. The condensate is naturally settled using the principle of gravity stratification and discharged through the drain pipe.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] In this invention, when high-temperature steam carrying condensate is ejected from the end of the outlet pipe, the metal filter allows the steam to pass through and directly blocks the droplets through its own dense mesh structure. At the same time, the steam impact force breaks up large droplets, achieving gas-liquid separation. Then, the droplets blocked and broken by the metal filter flow through the notch on the guide plate to the inner wall of the nozzle cover. The condensate adhering to the inner wall of the nozzle cover continues to diffuse to the diffuser holes under the action of gravity or airflow. The condensate overflows from the diffuser holes and adheres to the outer wall of the nozzle cover. Then, several diffuser holes concentrate the water droplets dispersed on the outer wall of the nozzle cover into the groove. The water droplets overflowing from the diffuser holes are further guided to the sponge for collection through the guide holes, reducing the risk of patients being scalded by high-temperature condensate dripping.

[0014] This invention features a nozzle assembly that allows steam to enter the housing through an inlet pipe. When the steam enters the housing, some of it condenses into condensate. Since the upper end of the inlet pipe is higher than the outlet pipe, the condensate settles naturally using the principle of gravity stratification and is then drained through the drain pipe.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0025] like Figures 1-6 As shown, this embodiment provides a condensate collection device for a fumigation machine, including a fixed cover 1 and a nozzle cover 2 disposed in front of the fixed cover 1. A nozzle assembly is disposed inside the fixed cover 1, and the nozzle assembly includes an air outlet pipe 3. Several air vents 4 are provided on the side wall of the nozzle cover 2. A fixing ring 5 is provided at the connection between the nozzle cover 2 and the fixed cover 1. One end of the air outlet pipe 3 passes through the fixed cover 1 and the fixing ring 5 and extends into the nozzle cover 2. A guide plate 6 is provided on one side of the fixing ring 5. A metal filter 7 is installed inside the guide plate 6. There is a gap between the side of the metal filter 7 and the end face of the air outlet pipe 3 extending into the nozzle cover 2. A protrusion 8 is provided on one side of the guide plate 6. Notches 9 are provided at both the upper and lower ends of the protrusion 8.

[0026] With the above-mentioned structure, when high-temperature steam carrying condensate is ejected from the end of the outlet pipe 3, the metal filter 7 allows the steam to pass through, and the dense mesh structure of the metal filter 7 directly blocks the droplets. At the same time, the steam impact force breaks up the large droplets, realizing gas-liquid separation. Then, the droplets blocked and broken by the metal filter 7 are guided to the inner wall of the nozzle cover 2 by the guide plate 6. The condensate adhering to the inner wall of the nozzle cover 2 continues to diffuse to the diffuser hole 4 under the action of gravity or airflow. The condensate overflows from the diffuser hole 4 and adheres to the outer wall of the nozzle cover 2. Then, several diffuser holes 4 concentrate the water droplets dispersed on the outer wall of the nozzle cover 2 into the groove 12. The water droplets overflowing from the diffuser hole 4 are further guided to the sponge 11 for collection through the guide hole 13.

[0027] Please refer to this again. Figure 4 The fixing ring 5 includes an inner ring 501 and an outer ring 502, which are coaxially connected. The inner ring 501 has a through hole at its center for the exhaust pipe 3 to pass through. The exhaust pipe 3 passes through the through hole in the fixing ring 5 and faces the metal filter screen 7. When high-temperature steam carrying condensate is ejected from the end of the exhaust pipe 3 and passes through the metal filter screen 7, a gas-liquid separation process occurs.

[0028] Please refer to this again. Figure 2 and Figure 3 The nozzle cover 2 is a conical cover with openings at both ends. The smaller end of the nozzle cover 2 is connected to the outer ring 502 by a screw. The larger end of the nozzle cover 2 is provided with an annular guide portion 10. A sponge 11 is provided inside the guide portion 10. An annular groove 12 is formed on one side of the guide portion 10. Several guide holes 13 are formed through the groove 12. The guide holes 13 are evenly distributed in the groove 12 of the guide portion 10.

[0029] In this embodiment, the guide plate 6 and the fixing ring 5 are connected by screws, and the protrusion 8 on the guide plate 6 is fitted to the fixing ring 5. By providing a notch 9 on the protrusion 8, the notch 9 is located between the fixing ring 5 and the protrusion 8. The droplets blocked and broken by the metal filter screen 7 are guided to the inner wall of the nozzle cover 2 through the notch 9.

[0030] In this utility model, one end of the fixing cover 1 is open and the other end is closed. The closed end of the fixing cover 1 is connected to the outer ring 502 by screws in three phases.

[0031] Please refer to this again. Figure 7The nozzle assembly also includes a housing 14 fixed to the closed end of the fixed cover 1. The air outlet pipe 3 is horizontally arranged at the left end of the housing 14, and the right end of the air outlet pipe 3 penetrates the left side of the housing 14 and extends into the housing 14. The lower end of the housing 14 is connected to a vertically arranged air inlet pipe 15, the upper end of the air inlet pipe 15 penetrates the bottom surface of the housing 14 and extends into the housing 14, and the upper end of the air inlet pipe 15 is higher than the air outlet pipe 3. The bottom surface of the housing 14 is provided with a drain pipe 16 that communicates with the inside of the housing 14, and the upper end of the drain pipe 16 is flush with the bottom surface of the housing 14. Steam enters the housing 14 through the air inlet pipe 15. When the steam enters the housing 14, some of the steam condenses into condensate. Since the upper end of the air inlet pipe 15 is higher than the air outlet pipe 3, the condensate settles naturally using the principle of gravity stratification and is discharged through the drain pipe 16.

[0032] The working principle of this utility model is as follows:

[0033] Please refer to this again. Figure 1 When high-temperature steam carrying condensate is ejected from the end of the outlet pipe 3, the metal filter 7 allows the steam to pass through and directly blocks the droplets through its own dense mesh structure. At the same time, the steam impact force breaks up large droplets, achieving gas-liquid separation. Then, the droplets blocked and broken by the metal filter 7 are guided to the inner wall of the nozzle cover 2 through the notch 9 on the guide plate 6. The condensate adhering to the inner wall of the nozzle cover 2 continues to diffuse to the diffuser hole 4 under the action of gravity or airflow. The condensate overflows from the diffuser hole 4 and adheres to the outer wall of the nozzle cover 2. Then, several diffuser holes 4 concentrate the water droplets dispersed on the outer wall of the nozzle cover 2 into the groove 12. The water droplets overflowing from the diffuser hole 4 are further guided to the sponge 11 for collection through the guide hole 13, reducing the risk of patients being scalded by high-temperature condensate dripping.
