Description

Technical Field

[0001] This utility model belongs to the field of electronic atomization technology, and in particular relates to an atomizer and an electronic atomization device. Background Technology

[0002] Atomizers consist of an oil cup and an atomizing assembly. In related technologies, the atomizing assembly incorporates multiple layers of liquid guides. The atomized liquid in the oil cup flows through and is stored within these layers, preventing excessive liquid from flowing directly to the atomizer coil and causing leakage. This results in better oil retention and reduces leakage issues. However, because adjacent layers of liquid guides are separated by tube walls, the liquid transfer rate between adjacent layers is relatively slow, potentially leading to poorer liquid delivery.

The inner tube has a second liquid inlet connecting the atomizing core and the second liquid guide; the atomizing core includes a heating element and a third liquid guide surrounding the heating element; in the radial direction, the outer tube has a first wall thickness a, and at least one of the first liquid guide and the second liquid guide has a first interference fit b with the outer tube; the inner tube has a second wall thickness c, and at least one of the second liquid guide and the third liquid guide has a second interference fit d with the outer tube, wherein 1.5a≤b≤2.5a; 1.5c≤d≤2.5c.

[0005] Furthermore, in some embodiments, the first wall thickness a is equal to the second wall thickness c, and the first interference fit amount b is equal to the second interference fit amount d.

[0006] Furthermore, in some embodiments, the difference between the first interference fit amount b and the first wall thickness a is 0.1 mm to 0.5 mm.

[0007] Furthermore, in some embodiments, the liquid inlet channel includes a liquid inlet disposed on the side wall of the outer cover; and / or, the liquid inlet channel includes a liquid inlet disposed on the side of the outer cover axially away from the base.

[0008] Furthermore, in some embodiments, the density of the first conductive liquid is less than the density of the second conductive liquid; and / or, the thickness of the first conductive liquid in the radial direction is less than or equal to the thickness of the second conductive liquid in the radial direction.

[0009] Furthermore, in some embodiments, the thickness of the first conductive liquid is 2 mm to 3 mm, and / or the thickness of the second conductive liquid is 3 mm to 4 mm.

[0010] Furthermore, in some embodiments, the base is provided with a first mounting groove with an opening facing the atomizing component, the outer cover passes through the first mounting groove, and the first mounting groove has a clearance opening that connects the liquid storage chamber and the liquid inlet channel.

[0011] Furthermore, in some embodiments, a second assembly groove communicating with the first assembly groove is provided on the side of the first assembly groove away from the opening, one end of the outer tube extends axially to the second assembly groove, and the outer side of the outer tube abuts against the sidewall of the second assembly groove.

[0012] Furthermore, in some embodiments, a third assembly groove communicating with the second assembly groove is provided on the side of the second assembly groove away from the opening, one end of the inner tube extends axially to the third assembly groove, and the outer side of the inner tube abuts against the sidewall of the third assembly groove.

[0013] Furthermore, in some embodiments, an electronic atomizing device includes a battery rod assembly and an atomizer as described above.

[0014] The atomizer in this invention has the following advantages compared with related technologies:

[0015] The atomizing assembly adopts a structure in which an outer cover, a first liquid guide, an outer tube, a second liquid guide, an inner tube, and an atomizing core are arranged radially in sequence. The atomizing liquid can be guided from the liquid storage chamber to the first liquid guide through the liquid inlet channel, and then from the first liquid guide to the second liquid guide through the first liquid guide hole. The atomized liquid of the second liquid guide can be guided to the third liquid guide of the atomizing core through the second liquid guide port for heating and atomization by the heating element. In this way, the atomizing assembly includes multiple layers of liquid guides, thereby achieving a better oil-locking effect.

[0016] In addition, a first fluid guide is provided on the outer side of the outer tube, and a second fluid guide is provided on the inner side of the outer tube. The first fluid guide and the outer tube can have an interference fit of amount b, or the second fluid guide and the outer tube can have an interference fit of amount b, or both the first and second fluid guides can have interference fits with the outer tube, with the sum of the two interference fits being b, resulting in an interference fit of amount ba between the first and second fluid guides. Since 1.5a ≤ b ≤ 2.5a, an interference fit of 0.5a to 1.5a exists between the first and second fluid guides, thus forming an oil bridge between them.

[0017] Furthermore, a second fluid guide is provided on the outer side of the inner tube, and a third fluid guide is provided on the inner side of the inner tube. The second fluid guide and the inner tube can have an interference fit of d, or the third fluid guide and the inner tube can have an interference fit of d, or both the second and third fluid guides can have interference fits with the inner tube, with the sum of the two interference fits being d, resulting in an interference fit of dc between the second and third fluid guides. Since 1.5c ≤ d ≤ 2.5c, an interference fit of 0.5c to 1.5c exists between the second and third fluid guides, thus forming an oil bridge between them. In this way, the first, second, and third fluid guides are sequentially connected to form a fluid transmission path, improving the fluid transmission effect while avoiding problems such as assembly difficulties due to excessive interference fit, reduced effective storage volume due to over-compression of the fluid guides, and poor fluid flow.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] Atomizers consist of an oil cup and an atomizing assembly. In related technologies, the atomizing assembly incorporates multiple layers of liquid guides. The atomized liquid in the oil cup flows through and is stored within these layers, preventing excessive liquid from flowing directly to the atomizer coil and causing leakage. This results in better oil retention and reduces leakage issues. However, because adjacent layers of liquid guides are separated by a tube wall, creating a gap the thickness of the tube wall, the liquid transfer rate between adjacent layers is relatively slow, potentially leading to poor liquid delivery.

[0038] Please see Figures 1 to 4 This utility model provides an atomizer, including a housing 1, a base 2, and an atomizing component 3. The base 2 is connected to one end of the housing 1. The atomizing component 3 is placed inside the housing 1 and forms a liquid storage chamber 100 with the base 2 and the housing 1. The atomizing component 3 includes an outer cover 31, a first liquid guide 32, an outer tube 33, a second liquid guide 34, an inner tube 35, and an atomizing core 36, which are arranged inside the outer cover 31 and sequentially connected radially from the outside to the inside. The outer cover 31 has a liquid inlet channel communicating with the liquid storage chamber 100 and the first liquid guide 32. The outer tube 33 has a first liquid guide port 331 communicating with the first liquid guide 32 and the second liquid guide 34. The inner tube 35 is provided with a second liquid guide port 351 that connects to the atomizing core 36 and the second liquid guide 34; the atomizing core 36 includes a heating element 361 and a third liquid guide 362 wrapped around the heating element 361; in the radial direction, the outer tube 33 has a first wall thickness a, and at least one of the first liquid guide 32 and the second liquid guide 34 has a first interference fit amount b with the outer tube 33; the inner tube 35 has a second wall thickness c, and at least one of the second liquid guide 34 and the third liquid guide 362 has a second interference fit amount d with the outer tube 33, wherein 1.5a≤b≤2.5a, 1.5c≤d≤2.5c.

[0039] In this embodiment of the invention, the atomizing component 3 is arranged radially in the following order: outer cover 31, first liquid guide 32, outer tube 33, second liquid guide 34, inner tube 35, and atomizing core 36. The atomizing liquid can be guided from the liquid storage chamber 100 through the liquid inlet channel to the first liquid guide 32, and then from the first liquid guide 32 through the first liquid guide hole to the second liquid guide 34. The atomizing liquid in the second liquid guide 34 can be guided through the second liquid guide port 351 to the third liquid guide 362 of the atomizing core 36 for heating and atomization by the heating element 361. Thus, the atomizing component 3 includes multiple layers of liquid guides, thereby achieving a better oil-locking effect.

[0040] In addition, a first liquid guide 32 is provided on the outer side of the outer tube 33, and a second liquid guide 34 is provided on the inner side of the outer tube 33. The first liquid guide 32 and the outer tube 33 may have a first interference fit amount b, or the second liquid guide 34 and the outer tube 33 may have a first interference fit amount b, or both the first liquid guide 32 and the second liquid guide 34 may have interference fit amounts with the outer tube 33, and the sum of the two interference fit amounts is the first interference fit amount b, so that there is an interference fit amount ba between the first liquid guide 32 and the second liquid guide 34. Since 1.5a≤b≤2.5a, there is an interference fit of 0.5a to 1.5a between the first liquid guide 32 and the second liquid guide 34. This allows an oil bridge to be formed between the first liquid guide 32 and the second liquid guide 34, resulting in an interference fit between the first liquid guide 32, the wall of the outer tube 33, and the second liquid guide 34. This enables the atomizing liquid to be quickly introduced from the first liquid guide 32 to the second liquid guide 34, thereby improving the liquid transfer effect between the first liquid guide 32 and the second liquid guide 34. At the same time, it avoids the problems of difficult assembly and easy structural damage caused by excessive interference fit.

[0041] In addition, a second liquid guide 34 is provided on the outer side of the inner tube 35, and a third liquid guide 362 is provided on the inner side of the inner tube 35. The second liquid guide 34 and the inner tube 35 may have a second interference fit amount d, or the third liquid guide 362 and the inner tube 35 may have a second interference fit amount d, or both the second liquid guide 34 and the third liquid guide 362 may have interference fit amounts with the inner tube 35, and the sum of the two interference fit amounts is the second interference fit amount d, so that there is an interference fit amount dc between the second liquid guide 34 and the third liquid guide 362. Furthermore, since 1.5c≤d≤2.5c, there is an interference fit of 0.5c to 1.5c between the second liquid guide 34 and the third liquid guide 362. This allows an oil bridge to be formed between the second liquid guide 34 and the third liquid guide 362, resulting in an interference fit between the first liquid guide 32, the wall of the outer tube 33, and the second liquid guide 34. This enables the atomizing liquid to be quickly introduced from the first liquid guide 32 to the second liquid guide 34, thereby improving the liquid transfer effect between the first liquid guide 32 and the second liquid guide 34. At the same time, it avoids the problems of difficult assembly and easy structural damage caused by excessive interference fit.

[0042] Therefore, in this embodiment of the utility model, the first liquid guide 32, the second liquid guide 34 and the third liquid guide 362 are connected in sequence to form a liquid guiding transmission path, which improves the volume transmission effect and avoids problems such as assembly difficulties caused by excessive interference fit, reduced effective liquid storage volume due to excessive compression of the liquid guide, and poor liquid guiding.

[0043] Understandably, when the first liquid guide 32 and the second liquid guide 34 have interference fit with the outer tube 33, the two interference fits can be the same or different; similarly, when the second liquid guide 34 and the third liquid guide 362 have interference fit with the inner tube 35, the two interference fits can be the same or different.

[0044] In some specific embodiments, the first liquid guide 32, the second liquid guide 34, and the third liquid guide 362 are all oil-wicking cotton.

[0045] It should be noted that this utility model has undergone reliability testing on the atomizer, including filling with oil for 30 seconds, lubricating the coil for 3 minutes, and exhibiting no burnt taste or oil leakage during inhalation, indicating that the atomizer is reliable.

[0046] For example, such as Figure 2 As shown, the axial direction is parallel to the X-axis.

[0047] Furthermore, in some embodiments, a equals c, and b equals d.

[0048] Specifically, the wall thicknesses of the inner tube 35 and the outer tube 33 can be the same; at the same time, b and d can be the same, so that ba and dc are equal, thereby making the interference fit between the first liquid guide 32 and the second liquid guide 34, as well as the interference fit between the second liquid guide 34 and the third liquid guide 362, equal, thus ensuring the liquid balance between the first liquid guide 32, the second liquid guide 34, and the third liquid guide 362, so that the atomization process can proceed in an orderly manner.

[0049] Furthermore, in some embodiments, the difference between b and a is 0.1 mm to 0.5 mm.

[0050] Specifically, the difference between b and a can be 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm, or 0.5mm, etc. Since there is an interference fit of ba between the first liquid guide 32 and the second liquid guide 34, setting the difference between b and a to 0.1mm to 0.5mm ensures that the interference fit between the first liquid guide 32 and the second liquid guide 34 is 0.1mm to 0.5mm. This allows the atomizing liquid to be quickly introduced from the first liquid guide 32 to the second liquid guide 34 while avoiding problems such as difficult assembly and easy structural damage caused by excessive interference fit.

[0051] In some embodiments, the difference between d and c can also be 0.1 mm to 0.5 mm. Specifically, it can be 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, or 0.5 mm, etc. This ensures that the interference fit between the second liquid guide 34 and the third liquid guide 362 is 0.1 mm to 0.5 mm, thereby allowing the atomizing liquid to be quickly introduced from the first liquid guide 32 to the second liquid guide 34 while avoiding problems such as difficult assembly and easy structural damage caused by excessive interference fit.

[0052] Furthermore, in some embodiments, the liquid inlet channel includes a liquid inlet 11 disposed on the side wall of the outer cover 31; and / or, the liquid inlet channel includes a liquid inlet 11 disposed on the side of the outer cover 31 axially away from the base 2.

[0053] Specifically, the atomizing component 3 is positioned above the base 2. In some implementations, a liquid inlet 11 can be provided on the top wall of the outer casing 31, allowing the atomizing liquid to be guided from the top wall inlet 11 to the first guiding liquid 32. In some implementations, a liquid inlet 11 can also be provided on the side wall of the outer casing 31, allowing the atomizing liquid to be guided from the side wall inlet 11 to the first guiding liquid 32. In some implementations, liquid inlets 11 can be provided on both the top and side walls of the outer casing 31, thereby enriching the liquid inlet channels for the atomizing liquid. When the liquid storage chamber 100 is full of oil, the atomizing liquid can be guided to the first guiding liquid 32 through different liquid inlets 11, which can avoid the influence of negative pressure in the liquid storage chamber 100 on the guiding liquid rate and ensure the stability of the liquid supply; when the amount of oil in the liquid storage chamber 100 decreases, the atomizing liquid can be guided to the first guiding liquid 32 through the liquid inlet 11 on the side wall, thus slowing down the oil flow rate, reducing leakage problems, and also ensuring the stability of the liquid supply.

[0054] In some embodiments, an inlet gap 320 communicating with the inlet 11 of the side wall can be provided between the first liquid guide 32 and the base 2. In this way, the atomizing liquid can flow from the inlet 11 of the side wall to the inlet gap 320 and then be guided to the first liquid guide 32. At the same time, the inlet gap 320 can also be used to ventilate the first liquid guide 32, so that the atomizing liquid can be quickly guided to the first liquid guide 32, avoiding the impact of negative pressure in the liquid storage chamber 100 on the oil injection speed and ensuring the stability of the liquid supply.

[0055] Furthermore, in some embodiments, the density of the first conductive liquid 32 is less than the density of the second conductive liquid 34. Specifically, the first conductive liquid 32 can be a low-density conductive liquid, and the second conductive liquid 34 can be a high-density conductive liquid. Radially, the first conductive liquid 32 is closer to the liquid storage cavity 100. Therefore, the low density of the first conductive liquid 32 allows for better liquid penetration and diffusion, ensuring a better liquid transport effect. The second conductive liquid 34 is farther from the liquid storage cavity 100. Therefore, in addition to transporting liquid to the atomizing core 36, the second conductive liquid 34 also needs to have a certain oil-locking ability. By setting the density of the second conductive liquid 34 to be higher, a good oil-locking effect can be achieved while ensuring smooth liquid transport.

[0056] Furthermore, in some embodiments, the thickness of the first liquid guide 32 in the radial direction is less than the thickness of the second liquid guide 34 in the radial direction. Radially, the first liquid guide 32 is closer to the liquid storage cavity 100; therefore, its smaller thickness allows for better liquid penetration and diffusion, ensuring a better liquid transport effect. The second liquid guide 34, being farther from the liquid storage cavity 100, needs to not only transport liquid to the atomizing core 36 but also possess a certain oil-locking ability. By setting the thickness of the second liquid guide 34 to be greater, a good oil-locking effect can be achieved while ensuring smooth liquid transport.

[0057] Furthermore, in some embodiments, the density of the first conductive liquid 32 is less than the density of the second conductive liquid 34, and the thickness of the first conductive liquid 32 in the radial direction is less than the thickness of the second conductive liquid 34 in the radial direction. In this way, the functions of the first conductive liquid 32 and the second conductive liquid 34 can be better utilized, and a good oil-locking effect can be achieved while ensuring a good liquid transmission effect.

[0058] Furthermore, in some embodiments, the thickness of the first liquid guide 32 is 2 mm to 3 mm, and / or the thickness of the second liquid guide 34 is 3 mm to 4 mm.

[0059] Specifically, the thickness of the first liquid conductor 32 can be 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, or 3mm, etc., and the thickness of the second liquid conductor 34 can be 3mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm, or 4mm. By setting the thickness of the first liquid conductor 32 to be relatively small and the thickness of the second liquid conductor 34 to be relatively large, the first liquid conductor 32 can better achieve liquid penetration and diffusion, ensuring a better liquid transport effect; it can also give full play to the oil-locking ability of the second liquid conductor 34.

[0060] Furthermore, in some embodiments, the base 2 is provided with a first assembly groove 21 with an opening facing the atomizing component 3, and the outer cover 31 passes through the first assembly groove 21. The first assembly groove 21 has a clearance opening 211 that connects the liquid storage chamber 100 and the liquid inlet channel. In this way, the base 2 and the outer cover 31 can be assembled and connected. The atomizing liquid in the liquid storage chamber 100 can flow through the clearance opening 211 of the first assembly groove 21 to the liquid inlet channel and then to the first liquid guide 32, realizing the conduction of the atomizing liquid.

[0061] In some specific embodiments, the liquid inlet channel includes a liquid inlet 11 disposed on the side wall of the outer cover 31, and a liquid inlet gap 320 located between the base 2 and the first liquid guide 32 and communicating with the liquid inlet 11. The first assembly groove 21 of the base 2 is provided with a clearance opening 211 corresponding to the liquid inlet 11. The atomizing liquid in the liquid storage chamber 100 can flow through the clearance opening 211 of the first assembly groove 21 to the liquid inlet 11, and then flow to the liquid inlet gap 320 to flow to the first liquid guide 32, thereby realizing the conduction of the atomizing liquid.

[0062] In some specific embodiments, the outer cover 31 has a plurality of spaced liquid inlets 11 along the circumferential direction. Correspondingly, the first assembly groove 21 has a relief opening 211 that corresponds one-to-one with the liquid inlets 11 along the circumferential direction. In this way, the liquid inlet path of the atomizing liquid can be dispersed, making the atomizing liquid of the first liquid guide 32 more uniform and improving the liquid transmission effect of the first liquid guide 32.

[0063] Furthermore, in some embodiments, a second assembly groove 22 communicating with the first assembly groove 21 is provided on the side away from the opening of the first assembly groove 21, and one end of the outer tube 33 extends axially to the second assembly groove 22, and the outer side of the outer tube 33 abuts against the side wall of the second assembly groove 22.

[0064] Specifically, with the atomizing component 3 on top and the base 2 on the bottom, the opening of the first assembly groove 21 faces upward. A second assembly groove 22 that connects to the first assembly groove 21 can also be opened on the bottom side of the first assembly groove 21. In this way, the outer side of the end of the outer tube 33 away from the opening can abut against the side wall of the second assembly groove 22, so that the outer tube 33 and the base 2 can be assembled and connected.

[0065] In some specific embodiments, the first liquid guide 32 and the outer cover 31 extend to the first assembly groove 21, and the outer tube 33 and the second liquid guide 34 extend to the second assembly groove 22. Thus, the outer cover 31 is clamped between the first assembly groove 21 and the first liquid guide 32. At the same time, the outer side of the outer tube 33 abuts against the first liquid guide 32 along the axial direction and another part abuts against the second assembly groove 22. The outer tube 33 is clamped between the first liquid guide 32 and the second liquid guide 34 along the axial direction, and another part of the outer tube 33 is clamped between the second assembly groove 22 and the second liquid guide 34 along the axial direction. In this way, the outer cover 31 and the base 2 can be assembled and connected, the outer cover 31, the first liquid guide 32, the outer tube 33 and the second liquid guide 34 can be assembled and connected, and the outer tube 33 and the base 2 can be assembled and connected.

[0066] Furthermore, in some embodiments, a third assembly groove 23 communicating with the second assembly groove 22 is provided on the side away from the opening of the second assembly groove 22, one end of the inner tube 35 extends to the third assembly groove 23 along the axial direction, and the outer side of the inner tube 35 abuts against the side wall of the third assembly groove 23.

[0067] Specifically, with the atomizing component 3 on top and the base 2 on the bottom, the opening of the first assembly groove 21 faces upward, and a third assembly groove 23 communicating with the second assembly groove 22 can be opened on the bottom side of the second assembly groove 22. In this way, the outer side of the end of the inner tube 35 away from the opening can abut against the side wall of the third assembly groove 23, so that the inner tube 35 and the base 2 can be assembled and connected.

[0068] In some specific embodiments, the first liquid guide 32 and the outer cover 31 extend to the first assembly groove 21, the outer tube 33 and the second liquid guide 34 extend to the second assembly groove 22, and the inner tube 35 and the atomizing core 36 extend to the third assembly groove 23. Thus, the outer cover 31 is clamped between the first assembly groove 21 and the first liquid guide 32. Simultaneously, the outer side of the outer tube 33 abuts against the first liquid guide 32 along its axial direction, and another portion abuts against the second assembly groove 22. The outer tube 33 is clamped between the first liquid guide 32 and the second liquid guide 34 along its axial direction, and another portion of the outer tube 33 is clamped between the second assembly groove 22 and the second liquid guide 34 along its axial direction. The inner tube 35 is positioned between the second liquid guide 34 and the third assembly groove 23. The outer axial portion of the inner tube 35 abuts against the second liquid guide 34, and the other portion abuts against the third assembly groove 23. The inner tube 35 is sandwiched between the second liquid guide 34 and the atomizing core 36, and the inner tube 35 is sandwiched between the third assembly groove 23 and the atomizing core 36. This allows for the assembly connection of the outer cover 31 and the base 2, the assembly connection of the outer tube 33 and the base 2, the assembly connection of the outer cover 31, the first liquid guide 32, the outer tube 33, the second liquid guide 34 and the atomizing core 36, and the assembly connection of the inner tube 35 and the base 2.

[0069] Furthermore, a second aspect of the present invention provides an electronic atomizing device, including a battery rod assembly and an atomizer.

[0070] Specifically, the atomizing component 3 adopts a structure in which an outer cover 31, a first liquid guide 32, an outer tube 33, a second liquid guide 34, an inner tube 35, and an atomizing core 36 are arranged radially in sequence. The atomizing liquid can be guided from the liquid storage chamber 100 through the liquid inlet channel to the first liquid guide 32, and then from the first liquid guide 32 through the first liquid guide hole to the second liquid guide 34. The atomizing liquid in the second liquid guide 34 can be guided through the second liquid guide port 351 to the third liquid guide 362 of the atomizing core 36 for heating and atomization by the heating element 361. In this way, the atomizing component 3 includes multiple layers of liquid guides, thereby achieving a better oil-locking effect.

[0071] Furthermore, a first fluid guide 32 is disposed on the outer side of the outer tube 33, and a second fluid guide 34 is disposed on the inner side of the outer tube 33. The first fluid guide 32 and the outer tube 33 can have an interference fit of amount b, or the second fluid guide 34 and the outer tube 33 can have an interference fit of amount b, or both the first fluid guide 32 and the second fluid guide 34 can have interference fits with the outer tube 33, with the sum of the two interference fits being b, resulting in an interference fit of amount ba between the first fluid guide 32 and the second fluid guide 34. Since 1.5a ≤ b ≤ 2.5a, an interference fit of 0.5a to 1.5a exists between the first fluid guide 32 and the second fluid guide 34, thus forming an oil bridge between them.

[0072] Furthermore, a second fluid guide 34 is provided on the outer side of the inner tube 35, and a third fluid guide 362 is provided on the inner side of the inner tube 35. The second fluid guide 34 and the inner tube 35 can have an interference fit of d, or the third fluid guide 362 and the inner tube 35 can have an interference fit of d, or both the second fluid guide 34 and the third fluid guide 362 can have an interference fit of dc with the inner tube 35, with the sum of the two interference fits being d. Since 1.5c ≤ d ≤ 2.5c, the second fluid guide 34 and the third fluid guide 362 have an interference fit of 0.5a to 1.5a, thus forming an oil bridge between them.

[0073] Thus, the first liquid guide 32, the second liquid guide 34 and the third liquid guide 362 are connected in sequence to form a liquid transport path, which improves the volume transport effect and avoids problems such as assembly difficulties caused by excessive interference fit, reduced effective liquid storage volume due to excessive compression of the liquid guide, and poor liquid transport.
