Description

Technical Field

[0001] The utility model belongs to the technical field of essential oil atomization, in particular to a labyrinth-type atomization cover and a fragrance machine. Background Art

[0002] The aromatherapy machine is a device consisting of an air compressor pump, a scent atomizer and a control panel. When in use, the air compressor pump will use compressed high-pressure air to hit the essential oil, and the essential oil will be atomized into tiny scent particles that diffuse out of the atomizer and diffuse into the air through the airflow.

[0003] In the prior art, for example, Chinese patent No. 202223096753.6 discloses a fragrance diffuser, which includes a housing, an air pump, a bottle body, and an atomizing cover. The air pump and the bottle body are installed in the housing, and the atomizing cover is installed on the bottle body. The bottle body is used to contain essential oils, and the atomizing cover is used to atomize the essential oils and spray them into the air. However, the essential oil of the device diffuses into the air with the airflow after being atomized by the atomizing cover. The atomizing cover cannot filter the spray of larger particles, and the spray flow distance of larger particles is shorter, which cannot improve the fragrance enhancement efficiency, but will cause waste of essential oils.

[0004] The utility model aims to improve the problem that the existing atomizing cover cannot filter the spray of larger particles, and provides a labyrinth atomizing cover and a fragrance machine.

[0005] The technical solutions to achieve the above objectives include the following:

The first channel is connected to the air inlet. The first opening is opened on the first wall portion, and the first channel is connected to the cache chamber through the first opening. The cache chamber is connected to the air outlet.

[0009] In one embodiment, the wall-like structure has a second wall portion, the first end and the second end of the first wall portion or the second wall portion are respectively abutted against the first cover body and the second cover body, the first wall portion and the second wall portion are both bent, the second wall portion is located on one side of the first wall portion, a first channel is formed in the first wall portion, and a second channel is formed between the first wall portion and the second wall portion, and the first channel, the first opening, the second channel, and the cache cavity are connected in sequence.

[0010] In one embodiment, the first wall portion and the second wall portion are both C-shaped, and the opening of the first wall portion and the opening of the second wall portion are arranged away from each other.

[0011] In one embodiment, the wall-like structure also has a third wall portion, and the two ends of the third wall portion are respectively abutted against the first cover body and the second cover body, the first wall portion and the second wall portion of the wall-like structure are both installed on the third wall portion, the third wall portion is an enclosing structure, the air outlet is located in the enclosing structure, the third wall portion has a second opening, and the air outlet is connected to the first opening through the second opening.

[0012] In one embodiment, the third wall portion has a spiral structure, and a spiral channel is formed between the inner wall and the outer wall of the third wall portion. The second opening is located at a first end of the spiral channel, and the second end of the spiral channel is connected to the air outlet.

[0013] In one embodiment, the bottom of the first cover body is inclined, the highest point of the bottom of the first cover body is arranged close to the air outlet, and the lowest point of the bottom of the first cover body is arranged close to the air inlet.

[0014] The utility model also proposes a fragrance machine, comprising a shell, an air pump, a first air pipe, a bottle body and the atomization cover as described above, wherein the atomization cover is installed on the bottle body, the first end of the first air pipe is installed on the air pump, and the second end of the first air pipe is clamped with the atomization cover; the bottle body and the air pump are both located in the shell, and the atomization cover is detachably connected to the shell.

[0015] In one embodiment, the atomizing cover has an atomizing mechanism, a straw, and a second air pipe, wherein the second air pipe is mounted on the cover body, the first end of the atomizing mechanism is mounted on the first end of the second air pipe, the straw is mounted on the second end of the atomizing mechanism, and the air pipe is at least partially located in the bottle body, and the second end of the second air pipe is clamped with the first air pipe.

[0016] In one embodiment, the atomization mechanism includes a first tube body and a second tube body, the first tube body and the second tube body are an integrated structure, the first end of the first tube body is connected to the second air pipe, the first end of the second tube body is connected to the straw, the second end of the first tube body is close to the second end of the second tube body, and forms an atomization processing position.

[0017] The technical solution provided by the utility model has the following advantages and effects:

[0018] 1. The essential oil spray enters the atomizing chamber from the air inlet and then flows out from the air outlet; by arranging a wall-like structure in the atomizing chamber, the wall-like structure separates the atomizing chamber, and when the spray enters the atomizing chamber, it contacts the wall-like structure, and the spray of larger particles will adhere to the side wall of the wall-like structure, and the air outlet and the air inlet are staggered, and the air outlet is connected with the air inlet through the first opening. By arranging the wall-like structure, the spray must pass through the first opening to flow out from the air outlet, and the spray moves back and forth in the atomizing chamber. The wall-like structure increases the round-trip distance of the spray from the air inlet to the air outlet. Due to its own weight, the spray of larger particles has a shorter flow distance with the air flow, and the spray of larger particles cannot flow to the air outlet. The spray of larger particles will fall into the atomizing chamber, and after a long period of accumulation, liquid essential oil is formed and flows to the air inlet, thereby improving the problem that the existing atomizing cover cannot filter the spray of larger particles, and avoiding the waste of essential oil.

[0019] 2. The first wall separates the atomizing chamber to form a buffer chamber and a first channel. The spray flow from the air inlet flows to the first channel, the first port and the buffer chamber in sequence. The spray of larger particles has a shorter flow distance. Therefore, when moving to the buffer chamber, the spray of larger particles will adhere to or fall into the buffer chamber. The buffer chamber is used to collect the spray of larger particles to prevent the larger particles from flowing out to the air outlet. The spray of smaller particles has a longer flow distance, so it will flow from the buffer chamber to the air outlet and diffuse into the air with the airflow outside the air outlet to improve the external environment.

[0020] 3. By setting the second wall portion, a second channel is formed between the first wall portion and the second wall portion, and the first channel, the first opening and the second channel are connected in sequence; the movement path of the spray in the atomization chamber is the air inlet, the first channel, the first opening, the second channel, the cache chamber, and the air outlet, and the second channel further increases the movement distance of the spray in the atomization chamber; and the first wall portion and the second wall portion are both bent, so that the first channel and the second channel are both bent, and the bent channel is used to increase the movement distance of the spray in the channel in a smaller space. As the movement distance of the spray in the atomization chamber increases, larger particles of spray will fall into the second channel and the cache chamber in sequence, further improving the filtering effect of the atomization cover.

[0021] 4. The first wall and the second wall are both C-shaped, and the opening of the first wall and the opening of the second wall are set far away from each other, increasing the distance that the spray moves from the first channel of the first wall to the second channel of the second wall, and further causing larger particles of the spray to fall into the first channel or the second channel.

[0022] 5. By setting the third wall portion, the first wall portion and the second wall portion are both installed on the third wall portion, so that the first wall portion, the second wall portion and the third wall portion form a wall-like structure with a stable structure; moreover, the third wall portion is an enclosed structure, the air outlet is located in the enclosed structure, the air outlet is connected with the first opening through the second opening, and the spray needs to pass through the first opening and the second opening when flowing to the air outlet, and the spray of larger particles further falls onto the third wall portion, further preventing the spray of larger particles from flowing to the air outlet.

[0023] 6. By setting the third wall portion as a spiral structure, a spiral channel is formed between the inner wall and the outer wall of the third wall portion. After the spray passes through the spiral channel, it flows to the air outlet. The spiral channel is used to further increase the moving distance of the spray in the atomization chamber, so that larger particles of spray fall into the spiral channel, further preventing larger particles of spray from flowing to the air outlet.

[0024] 7. By setting the bottom of the first cover body to an inclined shape, larger particles of spray accumulate at the bottom of the first cover body to form liquid essential oil, and flow back from the highest point to the lowest point in sequence. Since the lowest point of the bottom of the first cover body is close to the air inlet, the essential oil flows to the air inlet to achieve recycling; and the highest point of the bottom of the first cover body is close to the air outlet to avoid the essential oil from being retained near the air outlet, thereby avoiding affecting the recycling of the essential oil.

[0025] 8. The air pump is used to output high-pressure gas, which is sprayed toward the atomizing cap, forming a negative pressure state inside the atomizing cap. The atomizing cap under negative pressure will cause the essential oil in the bottle to flow toward the atomizing cap, and the high-pressure gas will blow away the essential oil in the atomizing cap, and make the essential oil atomized, and flow from the air inlet into the atomizing chamber; the atomizing cap is detachably connected to the shell, so that it is convenient to add essential oil to the bottle after taking out the atomizing cap and the bottle, which improves the convenience of the aroma diffuser and facilitates repeated use of the aroma diffuser. By setting up the atomizing cap, the spray of larger particles can be recycled to avoid wasting essential oil.

[0026] 9. The first end of the atomizing mechanism is connected to the second air pipe, and the second air pipe delivers high-pressure gas to the atomizing mechanism. The second end of the atomizing mechanism is connected to the straw, and the essential oil flows into the atomizing mechanism through the straw. When the atomizing mechanism is in a negative pressure state, due to the pressure difference, the essential oil in the straw is pressed into the atomizing mechanism and dispersed by the high-pressure gas, so that the liquid essential oil is converted into spray after passing through the high-pressure gas.

[0027] 10. The first tube body is used to transport high-pressure gas, and the second tube body is used to transport essential oil. The second end of the first tube body is close to the second end of the second tube body, and forms an atomization processing position. The high-speed airflow makes the atomization processing position in a negative pressure state. The pressure difference of the atomization processing position is that the essential oil continuously flows to the atomization processing position and is blown away by the high-pressure airflow; when the delivery of high-pressure gas is stopped, the negative pressure of the atomization processing position disappears, and the essential oil stops flowing to the atomization processing position.

[0043] like Figures 1 to 6As shown, a labyrinth-type atomizing cover 2 comprises a first cover body 22, a second cover body 21, and a wall-like structure 220, wherein the second cover body 21 is provided with an air outlet 23, and the first cover body 22 has an air inlet 226; the second cover body 21 is installed on the first cover body 22, and an atomizing chamber 20 is formed between the second cover body 21 and the first cover body 22, and the air inlet 226, the atomizing chamber 20 and the air outlet 23 are connected in sequence; the first end of the wall-like structure 220 abuts against the first cover body 22, and the second end of the wall-like structure 220 abuts against the second cover body 21, the wall-like structure 220 separates the atomizing chamber 20, and the wall-like structure 220 has at least one first through opening 2222, the air outlet 23 and the air inlet 226 are staggered, and the air outlet 23 is connected with the air inlet 226 through the first through opening 2222. The essential oil spray enters the atomizing chamber 20 from the air inlet 226 and then flows out from the air outlet 23; by setting the wall-like structure 220 in the atomizing chamber 20, the wall-like structure 220 separates the atomizing chamber 20, and when the spray enters the atomizing chamber 20, it contacts the wall-like structure 220, and the larger particles of the spray will adhere to the side wall of the wall-like structure 220. Moreover, the air outlet 23 and the air inlet 226 are staggered, and the air outlet 23 is connected to the air inlet 226 through the first opening 2222. By setting the wall-like structure 220, the spray must pass through the first opening 2222. 2222 can flow out from the air outlet 23, and the spray moves back and forth in the atomizing chamber 20. The wall-like structure 220 increases the round-trip distance of the spray from the air inlet 226 to the air outlet 23. The larger particles of spray have a shorter flow distance with the air flow due to their own weight, and the larger particles of spray cannot flow to the air outlet 23. The larger particles of spray will fall into the atomizing chamber 20, form liquid essential oil after a long period of accumulation, and flow to the air inlet 226, thereby improving the problem that the existing atomizing cover 2 cannot filter the larger particles of spray and avoiding the waste of essential oil.

[0044] like Figure 5 and Figure 6As shown, the wall-like structure 220 has a first wall portion 222, and the first wall portion 222 separates the atomization chamber 20 to separate the atomization chamber 20 into a cache chamber 2226 and a first channel 2221, and the first channel 2221 is connected to the air inlet 226, and the first opening 2222 is opened on the first wall portion 222, and the first channel 2221 is connected to the cache chamber 2226 through the first opening 2222, and the cache chamber 2226 is connected to the air outlet 23. The first wall portion 222 separates the atomizing chamber 20 so that the atomizing chamber 20 is divided into a buffer chamber 2226 and a first channel 2221. The spray flow of the air inlet 226 flows to the first channel 2221, the first port 2222 and the buffer chamber 2226 in sequence. The spray of larger particles has a shorter flow distance. Therefore, when the larger particles move to the buffer chamber 2226, they will adhere to or fall into the buffer chamber 2226. The buffer chamber 2226 is used to collect the spray of larger particles to prevent the larger particles from flowing out to the air outlet 23. The spray of smaller particles has a longer flow distance, so it will flow from the buffer chamber 2226 to the air outlet 23, and diffuse into the air along with the airflow outside the air outlet 23, thereby improving the external environment.

[0045] like Figure 5 and Figure 6 As shown, the wall-like structure 220 has a second wall portion 223, the first end and the second end of the first wall portion 222 or the second wall portion 223 are respectively abutted against the first cover body 22 and the second cover body 21, the first wall portion 222 and the second wall portion 223 are both bent, the second wall portion 223 is located on one side of the first wall portion 222, a first channel 2221 is formed in the first wall portion 222, a second channel 2223 is formed between the first wall portion 222 and the second wall portion 223, the first channel 2221, the first opening 2222, the second channel 2223, and the cache cavity 2226 are connected in sequence. By setting the second wall portion 223, a second channel 2223 is formed between the first wall portion 222 and the second wall portion 223, and the first channel 2221, the first opening 2222 and the second channel 2223 are connected in sequence; the moving path of the spray in the atomizing chamber 20 is the air inlet 226, the first channel 2221, the first opening 2222, the second channel 2223, the buffer chamber 2226, and the air outlet 23, and the second channel 2223 further increases the moving distance of the spray in the atomizing chamber 20; and the first wall portion 222 and the second wall portion 223 are both bent, so that the first channel 2221 and the second channel 2223 are both bent, and the bent channel makes full use of the space in the first cover body 22, and increases the moving distance of the spray in the channel in a limited space. As the moving distance of the spray in the atomizing chamber 20 increases, the spray of larger particles will fall into the second channel 2223 and the buffer chamber 2226 in sequence, further improving the filtering effect of the atomizing cover 2.

[0046] like Figure 5 and Figure 6 As shown, the first wall portion 222 and the second wall portion 223 are both C-shaped, and the opening of the first wall portion 222 and the opening of the second wall portion 223 are arranged far from each other. The opening of the first wall portion 222 and the opening of the second wall portion 223 are arranged far from each other, increasing the moving distance of the spray from the first channel 2221 of the first wall portion 222 to the second channel 2223 of the second wall portion 223, and further causing the spray of larger particles to fall into the first channel 2221 or the second channel 2223.

[0047] like Figure 5 and Figure 6 As shown, the wall-like structure 220 also has a third wall portion 224, and the two ends of the third wall portion 224 are respectively abutted against the first cover body 22 and the second cover body 21. The first wall portion 222 and the second wall portion 223 of the wall-like structure 220 are both installed on the third wall portion 224. The third wall portion 224 is an enclosed structure, and the air outlet 23 is located in the enclosed structure. The third wall portion 224 has a second opening 2225, and the air outlet 23 is connected to the first opening 2222 through the second opening 2225. By setting the third wall portion 224, the first wall portion 222 and the second wall portion 223 are both installed on the third wall portion 224, so that the first wall portion 222, the second wall portion 223 and the third wall portion 224 form a wall-like structure 220 with a stable structure; moreover, the third wall portion 224 is an enclosed structure, and the air outlet 23 is located in the enclosed structure. The air outlet 23 is connected with the first opening 2222 through the second opening 2225. When the spray flows to the air outlet 23, it needs to pass through the first opening 2222 and the second opening 2225. The larger particles of the spray further fall onto the third wall portion 224, further preventing the larger particles of the spray from flowing to the air outlet 23.

[0048] like Figure 5 and Figure 6 As shown, the third wall portion 224 is in a spiral structure, and a spiral channel 2224 is formed between the inner wall and the outer wall of the third wall portion 224. The second opening 2225 is located at the first end of the spiral channel 2224, and the second end of the spiral channel 2224 is connected to the air outlet 23. After the spray passes through the spiral channel 2224, it flows to the air outlet 23. The spiral channel 2224 is used to further increase the moving distance of the spray in the atomization chamber 20, so that the spray of larger particles falls into the spiral channel 2224, and further prevents the spray of larger particles from flowing to the air outlet 23.

[0049] like Figure 2As shown, the bottom of the first cover body 22 is inclined, the highest point of the bottom of the first cover body 22 is arranged near the air outlet 23, and the lowest point of the bottom of the first cover body 22 is arranged near the air inlet 226. By setting the bottom of the first cover body 22 to be inclined, the spray of larger particles accumulates at the bottom of the first cover body 22 to form liquid essential oil, and flows back from the highest point to the lowest point in sequence. Since the lowest point of the bottom of the first cover body 22 is arranged near the air inlet 226, the essential oil flows to the air inlet 226 to achieve recycling; and the highest point of the bottom of the first cover body 22 is arranged near the air outlet 23, so as to avoid the essential oil from being retained near the air outlet 23 and affecting the recycling of the essential oil.

[0050] In this embodiment, if Figure 2 and Figure 4 As shown, the end of the spiral channel 2224 close to the air outlet 23 is higher, and the spiral channel 2224 is lower near the second opening 2225. The essential oil in the spiral channel 2224 flows to the second opening 2225 and enters the second channel 2223. The essential oil in the second channel 2223 flows to the first opening 2222. The first opening 2222 is close to the air inlet 226, and the first opening 2222 is lower, so that the essential oil at the first opening 2222 flows to the air inlet 226; therefore, in the first channel 2221, the second channel 2223 and the spiral channel 2224, the slope of the bottom of the first cover body 22 is set according to the moving path of the essential oil flowing to the air inlet 226, and the air inlet 226 is located above the opening of the bottle body 3. The essential oil in the air inlet 226 will fall into the bottle body 3 to prevent the essential oil from being retained in the atomization chamber 20.

[0051] like Figures 1 to 4 The utility model further proposes a fragrance machine 100, comprising a shell 1, an air pump 4, a first air pipe 5, a bottle body 3 and the atomization cover 2 as described above, wherein the atomization cover 2 is installed on the bottle body 3, the first end of the first air pipe 5 is installed on the air pump 4, and the second end of the first air pipe 5 is clamped with the atomization cover 2; the bottle body 3 and the air pump 4 are both located in the shell 1, and the atomization cover 2 is detachably connected to the shell 1. The air pump 4 is used to output high-pressure gas, which is sprayed toward the atomizing cover 2, so that a negative pressure state is formed in the atomizing cover 2. The atomizing cover 2 under the negative pressure state will make the essential oil in the bottle 3 flow toward the atomizing cover 2, and the high-pressure gas will blow the essential oil in the atomizing cover 2 away, so that the essential oil is atomized and flows into the atomizing chamber 20 from the air inlet 226; the atomizing cover 2 is detachably connected to the housing 1, so that the essential oil can be added to the bottle 3 after the atomizing cover 2 and the bottle 3 are taken out, thereby improving the convenience of the aroma diffuser 100 and facilitating repeated use of the aroma diffuser 100. By setting the atomizing cover 2, the spray of larger particles can be recycled to avoid wasting essential oil.

[0052] like Figure 2 , Figure 3 as well as Figure 5 As shown, the atomizing cover 2 has an atomizing mechanism 24, a suction pipe 31, and a second air pipe 221. The second air pipe 221 is mounted on the cover body 2. The first end of the atomizing mechanism 24 is mounted on the first end of the second air pipe 221. The suction pipe 31 is mounted on the second end of the atomizing mechanism 24. The air pipe 31 is at least partially located in the bottle body 3. The second end of the second air pipe 221 is engaged with the first air pipe 5. The first end of the atomizing mechanism 24 is connected to the second air pipe 221. The second air pipe 221 delivers high-pressure gas to the atomizing mechanism 24. The second end of the atomizing mechanism 24 is connected to the suction pipe 31. The essential oil flows into the atomizing mechanism 24 through the suction pipe 31. When the atomizing mechanism 24 is in a negative pressure state, due to the pressure difference, the essential oil in the suction pipe 31 is pressed into the atomizing mechanism 24 and dispersed by the high-pressure gas, so that the liquid essential oil is converted into a spray after the high-pressure gas acts.

[0053] like Figure 7 As shown, the atomization mechanism 24 includes a first tube body 241 and a second tube body 242, the first tube body 241 and the second tube body 242 are an integrated structure, the first end of the first tube body 241 is connected to the second air pipe 221, the first end of the second tube body 242 is connected to the straw 31, the second end of the first tube body 241 is close to the second end of the second tube body 242, and an atomization processing position 243 is formed. The first tube body 241 is used to deliver high-pressure gas, and the second tube body 242 is used to deliver essential oil. The second end of the first tube body 241 is close to the second end of the second tube body 242, and an atomization processing position 243 is formed. The high-speed airflow makes the atomization processing position 243 in a negative pressure state, and the pressure difference of the atomization processing position 243 makes the essential oil flow to the atomization processing position 243 continuously and be blown away by the high-pressure airflow; when the delivery of high-pressure gas stops, the negative pressure of the atomization processing position 243 disappears, and the essential oil stops flowing to the atomization processing position 243.
