Description

Technical Field

[0001] The utility model belongs to the field of filter cartridges for moxibustion chairs, and specifically relates to a novel multi-layer composite filter cartridge. Background Art

[0002] The filter cartridge bin for moxibustion chair refers to a component or device used to store and replace the filter cartridge of the moxibustion chair. The moxibustion chair is a traditional Chinese medicine device that provides physical therapy to the human body through the heat generated by the burning of moxa leaves and the volatiles of the herbs. The filter cartridge is one of the important components in the moxibustion chair and is used to filter and absorb the smoke and odor generated by the burning of moxa leaves. The filter cartridge bin is usually located at the bottom or back of the moxibustion chair. It is a storage space for the filter cartridge. It is usually composed of a removable cover or door to facilitate users to replace the filter cartridge.

[0003] According to a Chinese patent publication number CN115737425A, a smokeless moxibustion chair is disclosed; the inner wall of the smoke exhaust channel and the outer wall of the smoke exhaust channel in the cited document form a smoke exhaust cavity, and the blower cooperates with the fan to extract the moxa smoke to the filter element for absorption. The temperature adjustment component is arranged on the inner wall of the smoke exhaust channel, which includes: a second motor, a screw rod, a slider sleeved on the screw rod, a housing fixed on the slider, and a temperature sensor arranged on the protective net;

[0004] In actual use, although the above-mentioned cited documents have solved the smoke-free use of moxibustion chairs, they still have certain limitations in use, that is, the smoke exhaust channel in the document lacks the collection and use of moxa oil. Since moxa smoke enters from the smoke inlet and the moxa smoke itself has temperature, it will change after long-term contact with the inner wall of the cold smoke exhaust channel, thereby adhering to the surface to form moxa oil, which will directly affect the normal use of the smoke exhaust channel. At the same time, these accumulated grease may cause the filter element to be blocked, affecting the filtering effect; at the same time, there is also the problem of using a single filter element structure in the cited document, and the single use of the filter element limits the filtering effect of smoke and odor, affecting normal use;

[0005] Furthermore, the air duct of the existing smoke filter bin has a straight-in and straight-out design, which may cause the moxa smoke to remain in the filter element for too short a time during use, resulting in incomplete purification of the moxa smoke. Therefore, in view of the problems of the above-mentioned cited documents and the existing filter element bins, a new multi-layer composite filter element bin is proposed to solve the problems. Utility Model Content

[0006] In response to one or more of the above-mentioned defects or improvement needs in the prior art, the utility model provides a new multi-layer composite filter element bin, which has the advantages of adopting a curved flue to increase the contact between moxa smoke and the filter element, thereby improving the effect of smoke-free use, adding a multi-layer composite filter element to improve the adsorption effect of moxa smoke, and adding an oil collecting part to realize the collection of moxa oil.

[0007] To achieve the above-mentioned purpose, the utility model provides a novel multi-layer composite filter cartridge, including a filter cartridge body, one side of the filter cartridge body is connected to a smoke inlet cartridge body, the smoke inlet cartridge body is a hollow box structure and forms a smoke inlet cavity; a condensation plate is provided at a distance between the connection between the filter cartridge body and the smoke inlet cartridge body;

[0008] A mounting frame is installed in the smoke inlet chamber, and a mugwort oil collecting groove is slidably arranged in the mounting frame; the mugwort oil collecting groove is a triangular box structure with an upper opening, and the mugwort oil collecting groove is arranged at the bottom of the smoke inlet chamber and its bottom wall is inclined;

[0009] A composite pressure point oil-absorbing cotton filter element, a HEPA filter element, and an activated carbon high-iodine filter element are embedded in the smoke filter bin.

[0010] As a further improvement of the present invention, the composite pressure point oil-absorbing cotton filter element, the HEPA filter element, and the activated carbon high-iodine filter element are arranged in sequence from left to right along the inner wall of the smoke filter chamber body; the composite pressure point oil-absorbing cotton filter element, the HEPA filter element, and the activated carbon high-iodine filter element are respectively provided with a spacing of 10-15MM, and the HEPA filter element has a thickened setting.

[0011] As a further improvement of the utility model, a hand-tightened bolt is threadedly connected to the side wall of the mounting frame, and a shell plate is detachably provided at the side wall of the wormwood oil collecting tank, and a handle is fixedly provided on the outer side wall of the shell plate.

[0012] As a further improvement of the present invention, the opening of the wormwood oil collection tank is arranged below the condensation plate and is arranged in close contact with the condensation plate.

[0013] As a further improvement of the utility model, two smoke duct inlets are opened on the top of the smoke inlet chamber body, and the two smoke duct inlets are vertically arranged above the wormwood oil collecting tank.

[0014] As a further improvement of the present invention, a flue pipe is provided in communication with the side wall of the cigarette filter bin body, and the flue pipe is provided at the bottom of the cigarette filter bin body.

[0015] In general, compared with the prior art, the above technical solutions conceived by the utility model have the following beneficial effects:

[0016] The novel multi-layer composite filter cartridge of the utility model, in actual use, the filter cartridge arranged in the filter cartridge body of the present application is increased and changed into a three-layer filter cartridge structure, which respectively comprises a composite pressure point oil-absorbing cotton filter cartridge, a HEPA filter cartridge and an activated carbon high-iodine filter cartridge, and a 10-15MM spacing is left between each layer of the filter cartridge. Compared with the use of a single filter cartridge in the cited document, the present application provides a certain buffering effect when purifying moxa smoke by setting a spacing between the filter cartridges, which enables the moxa smoke to fully contact the filter cartridge and maximize the smoke purification effect; at the same time, the multi-layer filter cartridge design ensures the thorough filtration of the moxa smoke and ensures the stable smoke-free use of the moxibustion chair.

[0017] The new multi-layer composite filter element bin of the utility model is connected with the flue inlet and the flue pipe. Compared with the traditional air duct with a straight in and out design, the present application adopts a curved air duct to maximize the contact time between the moxa smoke and the filter element, and a large space is reserved at the smoke inlet and the smoke outlet, thereby ensuring the smooth flow of the air duct and further improving the smoke exhaust effect.

[0018] In actual use, the new multi-layer composite filter element bin of the utility model enters the smoke inlet bin body from the flue inlet. At this time, the mugwort smoke itself has temperature, which will change due to long-term contact with the condensation plate, and then adhere to its surface to form mugwort oil. By providing a mugwort oil collecting tank below the flue inlet, the mugwort oil will slowly flow into the mugwort oil collecting tank below after it is formed, thereby completing the collection of the mugwort oil, thereby ensuring the stable use of the condensation plate and the filter element. The provided mugwort oil collecting tank can be quickly disassembled and cleaned from the smoke inlet bin body, thereby ensuring the stable and clean use of the present application during use.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] Depend on Figure 1-4 A novel multi-layer composite filter cartridge is provided, comprising a filter cartridge body 1, one side of the filter cartridge body 1 is connected to a smoke inlet cartridge body 2, the smoke inlet cartridge body 2 is a hollow box structure and forms a smoke inlet cavity; a condensation plate 4 is provided at a distance between the connection between the filter cartridge body 1 and the smoke inlet cartridge body 2;

[0027] A mounting frame 30 is assembled in the smoke inlet chamber body 2, and a mugwort oil collecting groove 3 is slidably arranged in the mounting frame 30; the mugwort oil collecting groove 3 is a triangular box structure with an upper opening, and the mugwort oil collecting groove 3 is arranged at the bottom of the smoke inlet chamber body 2 and its bottom wall is inclined;

[0028] A composite pressure point oil-absorbing cotton filter element 5, a HEPA filter element 6, and an activated carbon high-iodine filter element 7 are embedded in the smoke filter chamber body 1.

[0029] In the present embodiment, in actual use, the filter element arranged in the smoke filter chamber body 1 of the present application is increased and changed into a three-layer filter element structure, which are respectively a composite pressure point oil-absorbing cotton filter element 5, a HEPA filter element 6 and an activated carbon high-iodine filter element 7, and a 10-15MM spacing is left between each layer of the filter element. Compared with the use of a single filter element in the cited document, the present application sets a spacing between the filter elements, so that there is a certain buffering effect when purifying moxa smoke, which can make the moxa smoke fully contact with the filter element and maximize the smoke purification effect; at the same time, the multi-layer filter element design ensures the thorough filtration of the moxa smoke and ensures the stable smoke-free use of the moxibustion chair.

[0030] Furthermore, by setting the connection between the flue inlet 21 and the flue pipe 8, compared with the traditional air duct with a straight in and out design, the present application adopts a curved air duct to maximize the contact time between the moxa smoke and the filter element, and a large space is reserved between the smoke inlet and the smoke outlet, ensuring the smooth flow of the air duct, thereby further improving the smoke outlet effect.

[0031] Furthermore, in actual use, the wormwood smoke enters the smoke inlet chamber 2 from the flue inlet 21. At this time, the wormwood smoke itself has temperature, and it will change after long-term contact with the condensation plate 4, and then adhere to its surface to form wormwood oil. By setting a wormwood oil collecting tank 3 below the flue inlet 21, the wormwood oil will slowly flow into the wormwood oil collecting tank 3 below after it is formed, and then the collection of the wormwood oil is completed, thereby ensuring the stable use of the condensation plate 4 and the filter element. The wormwood oil collection tank 3 can be quickly disassembled and cleaned from the smoke inlet chamber 2, thereby ensuring the stable and clean use of the present application during use.

[0032] Furthermore, the present application adopts independent modularization between the smoke filter chamber body 1 and the smoke inlet chamber body 2. Compared with the integrated traditional smoke filter chamber equipment, the present application has better maneuverability in use, convenient disassembly and assembly, and simple later maintenance by independently modularizing the smoke filter chamber body 1.

[0033] Specifically, refer to Figure 1-4 The composite pressure point oil-absorbing cotton filter element 5, the HEPA filter element 6, and the activated carbon high-iodine filter element 7 are arranged along the inner wall of the smoke filter chamber 1 from left to right; the composite pressure point oil-absorbing cotton filter element 5, the HEPA filter element 6, and the activated carbon high-iodine filter element 7 are arranged at intervals of 10-15MM in sequence, and the HEPA filter element 6 has a thickened setting.

[0034] In the present embodiment, the filter element arranged in the smoke filter chamber body 1 of the present application is increased and changed into a three-layer filter element structure, which includes, from left to right, a composite pressure point oil-absorbing cotton filter element 5, a HEPA filter element 6 and an activated carbon high-iodine filter element 7; and a 10-15MM spacing is left between each layer of the filter element. By setting the spacing between the filter elements, a certain buffering effect is provided when purifying moxa smoke, so that the moxa smoke can be fully contacted with the filter element, and the smoke purification effect is maximized; at the same time, the HEPA filter element 6 is designed as a thickened version, which has excellent effects on service life and smoke purification efficiency.

[0035] It should be noted that, through testing, it was found that the composite pressure-point oil-absorbing cotton filter element 5 arranged on the first layer can be replaced after being used for about two times in practice, with two pieces of composite pressure-point oil-absorbing cotton placed each time. At the same time, an oil-absorbing cotton placement box is built into the smoke filter chamber 1. The HEPA filter element 6 arranged on the second layer can be replaced with a new one after being used for about 15 times, and the activated carbon high-iodine filter element 7 arranged on the third layer can be replaced with a new one after being used for about 30 times, thereby ensuring a better filtering effect.

[0036] Specifically, refer to Figure 1-3 A hand-tightened bolt 33 is threadedly connected to the side wall of the mounting frame 30 , and a shell plate 31 is detachably provided at the side wall of the wormwood oil collecting tank 3 , and a handle 32 is fixedly provided on the outer side wall of the shell plate 31 .

[0037] In the present embodiment, in actual use, when the wormwood smoke enters the smoke inlet chamber 2 through the flue inlet 21, the wormwood smoke produces wormwood oil under the long-term fumigation effect, and adheres to the condensation plate 4, and at the same time flows down through the condensation plate 4 until it enters the wormwood oil collecting tank 3. At this time, the wormwood oil can be collected in the wormwood oil collecting tank 3 due to the inclined setting of the bottom of the wormwood oil collecting tank 3. After the wormwood oil collecting tank 3 has been used for a period of time, the user can unscrew the two hand-tightening bolts 33. At this time, the hand-tightening bolts 33 set are detached from the mounting frame 30, so that the outer shell plate 31 and the wormwood oil collecting tank 3 can be disassembled as a whole. The user can pull the outer shell plate 31 and the wormwood oil collecting tank 3 out of the mounting frame 30 as a whole by holding the handle 32, so as to remove the wormwood oil collecting tank 3. At this time, the user can clean the wormwood oil collected in the wormwood oil collecting tank 3; after cleaning, the wormwood oil collecting tank 3 is inserted into the mounting frame 30 again, and the wormwood oil collecting tank 3 is locked on the mounting frame 30 using the hand-tightening bolts 33.

[0038] Specifically, refer to Figure 1-3 The opening of the wormwood oil collecting tank 3 is arranged below the condensation plate 4 and is arranged in close contact with the condensation plate 4.

[0039] In the present embodiment, in actual use, when the moxa smoke enters the smoke inlet chamber 2 through the flue inlet 21, the moxa smoke produces moxa oil under the long-term fumigation effect and adheres to the condensation plate 4, and at the same time flows down through the condensation plate 4 until it enters the moxa oil collection tank 3. The arranged condensation plate 4 can isolate and block the moxa oil, thereby keeping the composite pressure point oil-absorbing cotton filter element 5, HEPA filter element 6 and activated carbon high-iodine filter element 7 in the smoke filter chamber 1 for a longer life during use.

[0040] Specifically, refer to Figure 1-2 Two flue inlets 21 are provided on the top of the smoke inlet chamber body 2 , and the two flue inlets 21 are vertically arranged above the wormwood oil collecting tank 3 .

[0041] In this embodiment, the flue inlet 21 is provided for the entry of moxa smoke produced by fumigation, and then enters the smoke inlet chamber 2 through the flue inlet 21, and is drawn by external wind to pass through the composite pressure point oil-absorbing cotton filter element 5, the HEPA filter element 6, and the activated carbon high-iodine filter element 7.

[0042] Specifically, refer to Figure 1-4 A flue pipe 8 is connected to the side wall of the cigarette filter bin body 1 , and the flue pipe 8 is arranged at the bottom of the cigarette filter bin body 1 .

[0043] In the present embodiment, in actual use, when the moxa smoke enters the smoke inlet chamber 2 through the flue inlet 21, the user can set a fan on one side of the flue pipe 8, and use the extraction of the fan to make the moxa smoke enter through the flue inlet 21, and pass through the condensation plate 4, the composite pressure point oil absorption cotton filter element 5 and the HEPA filter element 6, the activated carbon high iodine filter element 7 in sequence, until it passes through the flue pipe 8. In a preferred embodiment, the direction of the moxa smoke is as shown in the embodiment Figure 4 As shown in the figure, the overall direction of the flue is Z-shaped. Compared with the traditional air duct which is a straight-in and straight-out design, the present application adopts a curved air duct to maximize the contact time between the moxa smoke and the filter element, and a large space is reserved at the smoke inlet and the smoke outlet, ensuring the smooth flow of the air duct, thereby further improving the smoke exhaust effect.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
