Description

Technical Field

[0001] The invention relates to a moxibustion apparatus, and in particular to a smoke exhaust and oil filter structure of the moxibustion apparatus. Background Art

[0002] Moxibustion instrument is a medical and health care device that uses the heat generated by burning moxa cakes to burn the acupuncture points and meridians of the human body. The moxibustion instrument is generally equipped with a moxibustion head for placing moxa cakes and a range hood for removing the smoke generated by the burning moxa cakes in the moxibustion head to prevent pollution of the workplace. The internal flue of the moxibustion head of the traditional moxibustion instrument is unreasonably set up, making it difficult to retain the oil stains and dust generated by the burning moxa cakes in the moxibustion head as much as possible, resulting in most of the oil stains and dust entering the filter element of the range hood, requiring frequent replacement of the filter element, increasing the cost of use.

[0035] The filter box 12.1 is centered and fixed on the inner rear wall of the rear box 11. The filter box 12.1 is also a front-opening rectangular box with longer top and bottom sides and shorter left and right sides. Its rear box surface is closely attached to the rear box surface of the rear box 11 and is locked and fixed to the inner rear wall of the outer box 11 by screws. The other surfaces of the filter box 12.1 are respectively spaced from the corresponding surfaces of the rear box 11 to partition a square annular smoke exhaust cavity 16 on the inner peripheral wall of the rear box 11. The rear box surface of the filter box 12.1 is centrally provided with an inner smoke exhaust pipe 12.11 that communicates its box cavity and the outer smoke exhaust pipe 11.2. One end of its bottom box surface is provided with a smoke inlet 12.12 that communicates its box cavity and the box cavity of the rear box 11. The other end of its bottom box surface is provided with a straight top slotted groove 12.13.

[0036] The isolation belt 12.2 includes an n-shaped section 12.21 and a straight section 12.22 provided at one end of the n-shaped section 12.21. The n-shaped section 12.21 is wound around the left and right sides and above the inner smoke exhaust pipe 12.11 at a distance. Its end far from the straight section 12.22 is located on the side of the inner smoke exhaust pipe 12.11 close to the smoke inlet 12.12 and is hermetically connected to the inner bottom surface of the filter box 12.1 to partition a rectangular smoke gathering cavity 12.14 communicating with the inner smoke exhaust pipe 12.11 in the filter box 12.1, and to form two mutually communicating filter cavities 12.15 in the box cavities of the filter box 12.1 on the left and right sides of the rectangular smoke gathering cavity 12.14. The straight section 12.22 closes the top opening of the straight top slotted groove 12.13 to form a straight smoke exhaust pipe 12.16 communicating with the rectangular smoke gathering cavity 12.14 at the inner bottom of the filter box 12.1. A smoke outlet 12.17 communicating the straight smoke exhaust pipe 12.16 and the filter cavity 12.15 above it is left between the distal end of the straight section 12.22 and the straight top slotted groove 12.13.

[0037] A number of filter grilles 12.3 are respectively arranged in the two filter cavities 12.15. The filter grilles 12.3 in the same filter cavity 12.15 are all spaced left and right and arranged staggeredly up and down. The filter grilles 12.3 located above are all fixed at the top to the filter box 12.1 and have a smoke passing gap at the bottom. The filter grilles 12.3 located below are fixed at the bottom to the filter box 12.1 and have a smoke passing gap at the top.

The cross-section of the moxa stick fixing plate 13.1 is in a shape of a capital "J" with one end open and the other end closed. The moxa stick fixing plate 13.1 is horizontally fixed to the front side of the filter box 12.1 with its groove facing outward to close the front opening of the filter box 12.1 through its groove bottom and form a front-opening combustion cavity 13.11 with its groove.

[0040] The top and bottom sides of the moxa stick fixing plate 13.1 correspond to and are fixedly connected to the inner folded edges 11.1 on the top and bottom sides of the outer box 11, and the closed end surface of the moxa stick fixing plate 13.1 is tightly against the inner folded edges 11.1 on the corresponding side surfaces of the outer box 11, so as to close the upper horizontal section, the lower horizontal section and one side vertical section of the square ring smoke exhaust groove 16 into a U-shaped smoke exhaust pipe 16.1, and the smoke inlet 12.11 is located at the side end of the lower horizontal section of the U-shaped smoke exhaust pipe 16.1.

[0041] The open end of the moxa stick fixing plate 13.1 is spaced apart from the corresponding surface of the outer box 11 so that the vertical section on the other side of the square ring smoke exhaust cavity 16 forms a smoke guide cavity 16.2 that connects the combustion cavity 13.11 to the two ends of the U-shaped smoke exhaust pipe 16.1.

[0042] A plurality of moxa stick fixing cups 13.2 are arranged side by side horizontally at the inner bottom of the combustion chamber 13.12 with the cup openings facing forward. The moxa stick fixing cup 13.2 is a round cup and is fixed to the inner bottom of the combustion chamber 13.11 through the cup bottom. The bottom of the moxa stick fixing cup 13.2 is uprightly provided with a moxa stick fixing needle 13.21, and the cup wall is symmetrically provided with at least two moxa stick smoke outlet holes 13.22.

[0043] An L-shaped filter plate 13.3 is provided between any two adjacent moxa cake fixing seat cups 13.2, and one folded surface of the L-shaped filter plate 13.3 is fixed in the combustion chamber 13.11 to separate the two adjacent moxa cake fixing cups 13.215, and the other folded surface is exposed in the cover cavity provided on the back of the front cover 15 and is bent in the direction away from the smoke guide cavity 16.2.

[0044] The baffle 14 is fixedly arranged on the outer side of the filter box 12.1 and the bottom thereof closes the lower transverse section port of the U-shaped smoke exhaust pipe 16.1, so that the combustion chamber 13.11 can only communicate with the upper transverse section port of the U-shaped smoke exhaust pipe 16.1 through the smoke guide cavity 16.2.

[0045] The front cover 15 is arranged at the front side of the rear box 11 to close the front opening of the rear box 11, and the cover surface is provided with moxibustion holes 15.1 corresponding to the front and rear of the plurality of moxa stick fixing cups 13.2, and each moxibustion hole 15.1 is enclosed with a mesh hole cover 15.2. The front cover 15 is connected to the outer box 11 through a hinge and is locked and fixed to the outer box 11 through a lock.

[0046] When in use, open the front cover 15, plug and fix a plurality of ignited round moxa cakes on the moxa cake fixing pins 13.21 in the moxa cake fixing cups 13.2, close the front cover 15, and the mesh hole cover 15.2 can keep the combustion chamber 13.11 ventilated so that the moxa cakes will not be extinguished. Start the range hood 60, the air intake of the range hood 60 is slightly greater than the air intake of the mesh hole cover 15.2, and the smoke generated by the burning of the moxa cake enters the smoke guide groove 16.2 directly or along the top of the L-shaped filter plate 13.3, and then enters the U-shaped smoke exhaust pipe 16.1 along the upper horizontal section port, and enters the filter chamber 12.15 along the smoke inlet 12.12, and then passes through the top or bottom of all the filter grilles 12.3 in turn, and then exits the moxibustion head 10 along the smoke outlet 12.17, the linear smoke exhaust pipe 12.16, the rectangular smoke collection chamber 12.14, and the inner smoke exhaust pipe 12.11, and is pumped out of the workplace by the range hood 60. The L-shaped filter plate 13.3 and the filter grille 12.3 absorb the dust and oil stains carried by the smoke, and most of the dust and oil stains are retained inside the moxibustion head 10. In addition, since the smoke exhaust channel of the present invention is longer and is blocked by the L-shaped filter 13.3 and the filter grid 12.3, the smoke stays in the moxibustion head 10 for a longer time, and the heat generated by the moxa cake is not easily dissipated too quickly. The moxibustion head 10 can maintain a higher therapeutic temperature, which is beneficial to improving the therapeutic effect.
