Description

Technical Field

[0001] The present disclosure relates to the technical field of washing equipment, and in particular, to a stirring and filtering device and a laundry treatment device. Background Art

[0002] Washing machines have become one of the most commonly used household electrical appliances. According to their working principles, washing machines on the market are mainly divided into three types: drum type, agitator type, and pulsator type. For an agitator washing machine, a vertical stirring rod is installed inside the washing tub. Stirring blades are installed in the area near the bottom of the tub. The stirring rod is driven by a motor to rotate periodically back and forth, thereby driving the stirring blades to swing and stir the clothes and water flow, and washing the clothes through the impact of the water flow and the friction between the clothes.

[0003] The filter of a traditional agitator washing machine is generally arranged on the barrel wall of the tub. The filter protrudes and is used to filter lint and sundries in the washing water. In the case where the stirring rod occupies the space of the tub, the setting of the filter further occupies the space of the tub and aggravates the wear of the clothes. Utility Model Content

[0004] In order to solve the above technical problems, the present disclosure provides a stirring and filtering device and a laundry treatment device to achieve a hidden design of the filter, avoid occupying the space of the tub, and reduce the wear of the clothes.

[0005] To achieve the above object, the first aspect of the present disclosure provides a stirring and filtering device, including:

[0006] A stirring rod, which has an installation cavity extending in a first direction inside. A plurality of stirring blades are arranged on the outer wall of the stirring rod. The plurality of stirring blades are spaced apart circumferentially along the stirring rod, and the stirring blades extend spirally in the first direction. A first water inlet channel communicating with the installation cavity is provided on the stirring rod, and the first water inlet channel is arranged along the extending direction of the stirring blade.

[0007] A filter, which is arranged in the installation cavity. The filter has a filtering cavity extending in the first direction and a second water inlet channel communicating the filtering cavity and the installation cavity.

[0008] The stirring and filtering device provided by the present disclosure arranges a filter in the installation cavity of a stirring rod. The filter has a filtering cavity. When the stirring rod rotates around the axis extending in the first direction, water flows into the filtering cavity through the first water inlet channel and the second water inlet channel. Foreign matters in the water continuously impact the cavity wall of the filtering cavity under the action of their own gravity and the centrifugal force received, and gradually accumulate towards the bottom end of the filtering cavity, realizing the filtering function. In this way, the filter is hidden and designed inside the stirring rod. Therefore, when applied to a laundry treatment device, there is no need to arrange a filter on the barrel wall of the barrel of the laundry treatment device, which can save the space of the barrel and reduce the wear on the clothes.

[0009] Moreover, the stirring rod is provided with a helically extending stirring blade and a first water inlet channel, which can make the first water inlet channel similar to the fluid form after being stirred by the stirring blade, so that the water flow can enter the installation cavity more smoothly, and then facilitate the water flow to enter the filtering cavity, improving the filtering effect.

[0010] In some embodiments, the first direction is the vertical direction;

[0011] The width of the stirring blade in the radial direction of the stirring rod gradually increases first and then decreases from the upper end to the lower end of the stirring rod in the vertical direction.

[0012] In some embodiments, multiple rows of the first water inlet channels are arranged between two adjacent stirring blades, and the multiple rows of the first water inlet channels are spaced apart in the circumferential direction of the stirring rod.

[0013] In some embodiments, the first water inlet channel includes a plurality of first water inlet holes.

[0014] In some embodiments, the filtering cavity is a conical cavity, and from the first end to the second end of the stirring rod in the first direction, the cross-sectional area of the conical cavity gradually decreases in a direction perpendicular to the first direction.

[0015] In some embodiments, a plurality of the second water inlet channels are provided, and the plurality of the second water inlet channels are spaced apart in the circumferential direction of the filter. The second water inlet channels extend helically in the first direction and have the same helical direction as the projection of the first water inlet channel on the filter.

[0016] In some embodiments, the second water inlet channel includes a water inlet groove and a plurality of second water inlet holes arranged in the water inlet groove. The water inlet groove extends helically in the first direction, and the plurality of second water inlet holes are spaced apart in the extending direction of the water inlet groove.

[0017] In some embodiments, the first direction is the vertical direction;

[0018] The extending direction of the second water inlet hole is inclined downward relative to the vertical direction.

[0019] In some embodiments, a first end of the stirring rod in the first direction has an installation opening for the filter to extend into the installation cavity. The filter is detachably connected to the stirring rod and can cover the installation opening.

[0020] In some embodiments, the filter is divided into a collection section and a main body section in the first direction. The filter cavity penetrates through the collection section and the main body section, and the second water inlet channel is formed on the main body section.

[0021] The collection section is closer to the second end of the stirring rod in the first direction than the main body section.

[0022] The second aspect of the present disclosure provides a clothing treatment device, including a barrel body and the stirring and filtering device provided in the first aspect. The stirring and filtering device is arranged inside the barrel body, and the first direction is the vertical direction, so that the clothing treatment device also has the above technical effects.

[0035] In order to more clearly understand the above-mentioned objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0036] Many specific details are set forth in the following description in order to fully understand the present disclosure, but the present disclosure may be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0037] The stirring and filtering device will be described in detail through specific embodiments as follows:

[0038] The present disclosure provides a stirring and filtering device 10, which is applicable to a laundry treatment device. The laundry treatment device includes a barrel body 20, and the stirring and filtering device is arranged inside the barrel body 20. The stirring and filtering device 10 can stir the clothes and water in the barrel body 20 and filter the water. The laundry treatment device can be selected as a washing machine, such as a stir-type washing machine.

[0039] Referring to Figures 1 to 5 , the stirring and filtering device 10 includes a stirring rod 1 and a filter 2.

[0040] Specifically, the stirring rod 1 has an installation cavity 101 extending in a first direction inside. The outer wall of the stirring rod 1 is provided with a plurality of stirring blades 12. The plurality of stirring blades 12 are arranged at intervals along the circumferential direction of the stirring rod 1, and the stirring blades 12 extend spirally in the first direction. A first water inlet channel 11 communicating with the installation cavity 101 is opened on the stirring rod 1, and the first water inlet channel 11 is arranged along the extending direction of the stirring blades 12. The filter 2 is arranged in the installation cavity 101. The filter 2 has a filter cavity 201 extending in the first direction and a second water inlet channel 202 communicating with the installation cavity 101. Among them, the first direction is the X direction as Figure 1 shown.

[0041] Understandably, the filter 2 is disposed within the installation cavity 101 of the stirring rod 1. The filter 2 has a filtering cavity 201. When the stirring rod 1 rotates about the axis extending in the first direction, water flows through the first water inlet passage 11 and the second water inlet passage 202 into the filtering cavity 201. Foreign matters in the water continuously impact the cavity wall of the filtering cavity 201 under the action of their own gravity and centrifugal force, and gradually accumulate towards the bottom end of the filtering cavity 201, achieving the filtering function. In this way, the filter 2 is hidden and designed inside the stirring rod 1. Therefore, when applied to a laundry treatment device, there is no need to provide a filter on the barrel wall of the barrel of the laundry treatment device, which can save the space of the barrel and reduce the wear on the clothes.

[0042] Moreover, the stirring rod 1 is provided with a stirring blade 12 extending spirally and the first water inlet passage 11, which can make the first water inlet passage 11 similar to the fluid form after being stirred by the stirring blade 12, so that water can enter the installation cavity 101 more smoothly, and then facilitate the water to enter the filtering cavity 201, improving the filtering effect.

[0043] In addition, by installing the filter 2 inside the stirring rod 1, there is no need to provide a structure for installing the filter 2 on the barrel, improving the integrity of the barrel structure.

[0044] It should be noted that the above-mentioned first direction is the X direction as shown in Figure 1 , and at this time the first direction is the vertical direction. The stirring rod 1 extends in the first direction, that is, the stirring rod 1 is vertically arranged. Among them, the stirring rod 1 has a first end and a second end in the first direction. When the first direction is the vertical direction, the first end is located above the second end.

[0045] Referring to Figure 1 , the above-mentioned stirring blade 12 spirally extends along the first direction on the stirring rod 1, and the spiral extension of the stirring blade 12 is continuous. Among them, continuous means that the stirring blade 12 has no interruption in the first direction. The stirring blade 12 continuously moves from the starting point around the first direction and the circumferential direction of the stirring rod 1 to the end point, so as to achieve a better effect on the up and down turning of the clothes, and at the same time improve the wetting and washing of the clothes by water, improving the washing effect on the clothes.

[0046] Furthermore, a plurality of stirring blades 12 are evenly spaced along the circumferential direction of the stirring rod 1, so as to evenly turn the clothes, making the washing of the clothes more uniform and improving the washing effect.

[0047] Optionally, the projections of two adjacent stirring blades 12 on the plane perpendicular to the first direction do not overlap, that is, the projections of the two stirring blades 12 on the plane perpendicular to the first direction have no overlapping parts, which can reduce the number of stirring blades 12 and reduce the cost.

[0048] Exemplarily, in a specific implementation, referring to Figure 1 , three stirring vanes 12 are provided, and the three stirring vanes 12 are evenly spaced in the circumferential direction of the stirring rod 1.

[0049] Referring to Figure 1 , the above-mentioned first direction is the vertical direction, and the width of the stirring vane 12 in the radial direction of the stirring rod 1 gradually increases first and then gradually decreases from the upper end to the lower end of the stirring rod 1 in the vertical direction. Among them, the radial direction of the stirring rod 1 is perpendicular to the vertical direction.

[0050] It can be understood that in the vertical direction, the width of the stirring vane 12 is small at both ends and large in the middle. In this way, when the stirring rod 1 stirs, the clothes can be turned more, thereby increasing the friction between the clothes and the water flow and improving the washing effect.

[0051] Referring to Figure 1 , a plurality of first water inlet channels 11 are provided between two adjacent stirring vanes 12, and the plurality of first water inlet channels 11 are spaced in the circumferential direction of the stirring rod 1.

[0052] It can be understood that by providing a plurality of first water inlet channels 11, the probability of water flow entering the installation cavity 101 can be further increased, thereby promoting the water flow to enter the filtering cavity 201 and improving the filtering effect.

[0053] Further, the first water inlet channels 11 located between two adjacent stirring vanes 12 are divided into two groups, each group includes at least one first water inlet channel 11, and one group of first water inlet channels 11 extends from the first end to the second end of the stirring rod 1 in the first direction, and the other group of first water inlet channels 11 extends from the second end to the first end of the stirring rod 1 in the first direction.

[0054] Among them, the lengths of two adjacent first water inlet channels 11 are the same or equal.

[0055] Exemplarily, in a specific implementation, referring to Figure 1 , the lengths of two adjacent first water inlet channels 11 in each group are different. Along the circumferential direction of the stirring rod 1, among two adjacent first water inlet channels 11 in each group of first water inlet channels 11, the length of the first water inlet channel 11 relatively closer to the other group of first water inlet channels 11 is greater than that of the other first water inlet channel 11.

[0056] For ease of description, two adjacent stirring vanes 12 are respectively defined as the first stirring vane and the second stirring vane, and two groups of first water inlet channels between the two stirring vanes 12 are defined as the first group and the second group, wherein the first group is closer to the first stirring vane than the second group. Among the two adjacent first water inlet channels 11 in the first group, the length of the first water inlet channel 11 closer to the second stirring vane is greater than the length of the other first water inlet channel 11. In this way, the overall of the multiple first water inlet channels 11 between two adjacent stirring vanes 12 also presents a spiral shape, so that the arrangement of the multiple first water inlet channels 11 is similar to the fluid form of the water flow when the stirring vanes 12 stir, which is beneficial to making the water flow into the installation cavity 101 more smoothly through the first water inlet channels 11.

[0057] In a specific implementation manner, referring to Figure 1 , six first water inlet channels 11 are provided between two adjacent stirring vanes 12. The six first water inlet channels 11 are evenly divided into two groups. Among them, the first group of first water inlet channels 11 extends from the first end to the second end of the stirring rod 1 in the first direction, and the second group of first water inlet channels 11 extends from the second end to the first end of the stirring rod 1 in the first direction. And among the two adjacent first water inlet channels 11 in the first group, the length of the first water inlet channel 11 relatively closer to the second group is greater than the length of the other first water inlet channel 11. Among the two adjacent first water inlet channels 11 in the second group, the length of the first water inlet channel 11 relatively closer to the first and second groups is greater than the length of the other first water inlet channel 11.

[0058] In a specific implementation manner, referring to Figure 1 , the above-mentioned first water inlet channel 11 includes a plurality of first water inlet holes 111. The plurality of first water inlet holes 111 are arranged at intervals along the extending direction of the first water inlet channel 11. In this way, the length of the first water inlet channel 11 can be changed only by changing the number of the first water inlet holes 111 included in the first water inlet channel 11. Of course, the above-mentioned first water inlet channel 11 can also be set to include only one water inlet hole, and at this time the water inlet hole is strip-shaped.

[0059] As Figures 1 to 2 shown, the first end of the stirring rod 1 in the first direction has an installation opening for the filter 2 to extend into the installation cavity 101. The filter 2 is detachably connected to the stirring rod 1 and can cover the installation opening.

[0060] Understandably, setting the filter 2 to be detachably connected to the stirring rod 1 can facilitate the removal of the filter 2 from the stirring rod 1 to pour out the foreign matters in the filter cavity 201 and facilitate the cleaning of the filter 2.

[0061] Continue according to Figure 1 and Figure 2, the above-mentioned filter 2 includes a filter cartridge 21 and a filter cover 22. The filter cartridge 21 has the above-mentioned filter chamber 201. One end of the filter cartridge 21 is provided with a covering opening, and the filter cover 22 is detachably covered on the covering opening.

[0062] That is to say, the filter cover 22 can open or close the covering opening of the filter cartridge 21. In this way, after the filter 2 is used for a period of time, the foreign matters in the filter cartridge 21, such as lint and fluff, can be cleaned by opening the covering opening through the filter cover 22, realizing the reuse of the filter 2 and reducing the cost.

[0063] In some embodiments, the above-mentioned filter cartridge 21 can be integrally formed, for example, by injection molding, without secondary processing, which can reduce the production cost and is beneficial to wide promotion.

[0064] Furthermore, the filter cover 22 or the filter cartridge 21 is detachably connected to the stirring rod 1, and the filter cover 22 can cover the installation opening.

[0065] It should be noted that in the first direction, which is the vertical direction, the filter cover 22 is covered on the upper end of the filter cartridge 21 in the vertical direction. At this time, the bottom end of the filter cartridge 21 is used to collect foreign matters.

[0066] It can be understood that the filter 2 can be connected to the stirring rod 1 through the filter cover 22 or the filter cartridge 21 to realize the installation of the filter 2, and can also be detached from the stirring rod 1 and taken out through the installation opening. In this way, it is convenient to remove the filter 2 to clean the foreign matters in the filter cartridge 21, improving its practicability.

[0067] Preferably, the filter cover 22 or the filter cartridge 21 is snap-connected to the stirring rod 1. Taking the snap connection between the filter cover 22 and the stirring rod 1 as an example, a snap projection is provided on the outer periphery of the filter cover 22, and a snap groove is provided on the inner wall of the stirring rod 1. The snap projection and the snap groove cooperate to realize the snap connection between the filter cover 22 and the stirring rod 1. When assembling the filter cover 22 and the stirring rod 1, the filter cover 22 is pushed forcefully in the direction of extending into the installation cavity 101 until the snap projection enters the snap groove. When disassembling the filter cover 22 and the stirring rod 1, the filter cover 22 is pulled forcefully in the direction of being withdrawn from the installation cavity, so that the snap projection is disengaged from the snap groove.

[0068] It should be noted that the snap projection has a guiding curved surface or a guiding inclined surface, so that the snap projection can smoothly enter the snap groove or be disengaged from the snap groove.

[0069] Of course, the connection between the filter cover 22 or the filter cartridge 21 and the stirring rod 1 can also adopt plug-in connection, screw connection and other methods, which will not be listed one by one here.

[0070] Furthermore, referring to Figure 2 and Figure 3, the filter cartridge 21 is separated in the first direction to form a collection section 212 and a main body section 211. The filter chamber 201 penetrates through the collection section 212 and the main body section 211. A second water inlet channel 202 is formed on the main body section 211. The collection section 212 is closer to the second end of the stirring rod 1 in the first direction than the main body section 211.

[0071] That is to say, the filter cartridge 21 is an integral body and is structurally divided into a collection section 212 and a main body section 211. The collection section 212 is closer to the second end of the stirring rod 1 in the first direction than the main body section 211 and no second water inlet channel 202 is formed thereon. In this way, after the water flow enters the filter chamber 201 through the second water inlet channel 202 on the main body section 211, the foreign matters in the water flow move towards the lower end of the filter cartridge 21 under the action of centrifugal force and its own gravity and enter the filter chamber 201 of the collection section 212. In this way, it is possible to prevent the deposited foreign matters from being directly impacted by the water flow entering the filter chamber 201 from the second water inlet channel 202, which is beneficial to improving the stability of the foreign matters in the collection section 212.

[0072] Optionally, it can also be that the filter cartridge includes a main cylinder body with a filter chamber and a collection cylinder with a collection chamber; a second water inlet channel is formed on the main cylinder body. The main cylinder body is detachably connected to the collection cylinder, and the filter chamber communicates with the collection chamber. The collection cylinder is closer to the second end of the stirring rod 1 in the first direction than the main cylinder body. That is to say, the filter cartridge is composed of two parts, which are connected by the main cylinder body and the collection cylinder. Since the collection cylinder is located at the second end of the filter cartridge and is detachably connected to the main cylinder body, after the filter cartridge is taken out of the installation cavity, the foreign matters in the collection cylinder can be cleaned by disassembling the collection cylinder.

[0073] Or it can also be that the filter cartridge includes a main cylinder body with a filter chamber and a collection cylinder with a collection chamber; a second water inlet channel is formed on the main cylinder body. The main cylinder body is detachably connected to the collection cylinder, and the filter chamber communicates with the collection chamber. The collection cylinder is closer to the second end of the stirring rod 1 in the first direction than the main cylinder body. At this time, the collection cylinder is located below the main cylinder body.

[0074] Refer to Figures 3 to 5 , the first direction is the vertical direction. The above-mentioned filter chamber 201 is a conical chamber, and from the upper end to the lower end of the stirring rod 1 in the vertical direction, the cross-sectional area of the filter chamber 201 in the direction perpendicular to the first direction gradually decreases.

[0075] Taking a washing machine as an example of the laundry treatment device, the water entering the conical cavity rotates rapidly along the cavity wall of the conical cavity. Different substances generate different centrifugal forces during rapid rotation. The density of foreign matters such as lint is greater than that of water, and the foreign matters have greater inertia. Therefore, under the action of centrifugal force and their gravity, they continuously impact the cavity wall of the conical cavity and move towards the second end of the filter cylinder 21. That is, foreign matters such as lint move downward and finally fall to the bottom of the filter cylinder 21, realizing the filtration and collection of foreign matters in the water. Among them, the movement route of foreign matters in the water is as shown in Figure 4 the spiral line shown in.

[0076] Furthermore, the above-mentioned filtration cavity 201 is preferably a conical cavity. At this time, the cross-section of the filtration cavity 201 perpendicular to the first direction is circular, and the inner diameter of the filtration cavity 201 gradually decreases from the first end to the second end of the filter cylinder 21. Optionally, in other embodiments, the cross-section of the filtration cavity perpendicular to the first direction can also be an elliptical cone and a rectangle.

[0077] Furthermore, the cavity wall of the above-mentioned conical cavity is smooth and flat to reduce the friction between the water and the cavity wall of the conical cavity, so as to promote the foreign matters to move towards the second end of the filter cylinder 21 close to the stirring rod in the first direction.

[0078] Referring to Figures 2 to 5 , a plurality of the above-mentioned second water inlet channels 202 are provided. The plurality of second water inlet channels 202 are arranged at intervals in the circumferential direction of the filter 2. The second water inlet channels 202 extend spirally in the first direction and have the same spiral direction as the first water inlet channel 11.

[0079] That is to say, a plurality of second water inlet channels 202 are arranged along the circumferential direction of the filter cylinder 21. The second water inlet channels 202 extend spirally in the first direction and have the same spiral direction as the projection of the first water inlet channel 11 on the filter 2. In this way, the setting method of the second water inlet channels 202 is the same as that of the first water inlet channel 11 on the stirring rod 1. The water flow entering the installation cavity 101 from the first water inlet channel 11 is further swirled into the filtration cavity 201 through the second water inlet channels 202 under the action of inertia, so as to improve the filtration effect.

[0080] Exemplarily, in a specific implementation manner, referring to Figure 3 , the second water inlet channel 202 includes a water inlet groove 2021 and a plurality of second water inlet holes 2022 arranged in the water inlet groove 2021. The water inlet groove 2021 extends spirally in the first direction, and the plurality of second water inlet holes 2022 are arranged at intervals in the extending direction of the water inlet groove 2021.

[0081] By providing the water inlet tank 2021 and the second water inlet holes 2022, the structural strength of the filter cartridge 21 can be increased, the stability of the filter cartridge 21 during rotation can be improved, and deformation can be reduced. Moreover, providing multiple second water inlet holes 2022 can also prevent foreign objects entering the filter chamber 201 from being easily thrown out.

[0082] Further, with reference to Figure 5 , the above first direction is the vertical direction, the second water inlet holes 2022 are arranged obliquely downward relative to the vertical direction, and the side of the second water inlet holes 2022 communicating with the filter chamber 201 is located below the side communicating with the water inlet tank 2021.

[0083] It can be understood that by arranging the second water inlet passage 202 obliquely, the water flow has a tendency to move towards the lower end of the filter chamber 201 when entering the filter chamber 201. Thus, foreign objects in the water flow also have a tendency to move towards the lower end of the filter chamber 201, thereby accelerating the movement speed of foreign objects towards the lower end of the filter chamber 201 as the filter cartridge 21 rotates, which is beneficial to the rapid deposition of foreign objects in the water flow and improves the filtration efficiency.

[0084] Optionally, in another specific implementation manner, the second water inlet passage can also be set as a through hole extending spirally along the first direction, so as to increase the communication area between the filter chamber and the installation chamber.

[0085] The embodiment of the present disclosure also provides a laundry treatment device, including a tub 20 and the above-mentioned stirring and filtering device 10, and the stirring and filtering device is arranged inside the tub. This laundry treatment device has the technical effects of the stirring and filtering device in the above embodiment, which will not be elaborated here.

[0086] With reference to Figure 6 , the above laundry treatment device can be a washing machine, especially an agitator washing machine. This laundry treatment device includes a tub 20 and a pulsator 30, and the stirring rod 1 is arranged inside the tub 20 and connected to the pulsator 30. The tub 20 is arranged inside a cabinet 40, and the pulsator 30 is driven by a motor arranged inside the cabinet 40 to drive the stirring rod 1 to rotate for washing clothes.

[0087] Exemplarily, with reference to Figures 1 to 5, the first direction is the vertical direction. The stirring rod 1 has an installation cavity 101 extending in the vertical direction inside. A plurality of stirring blades 12 are arranged on the outer wall of the stirring rod 1. The plurality of stirring blades 12 are arranged at intervals along the circumferential direction of the stirring rod 1, and the stirring blades 12 extend spirally in the first direction. A first water inlet channel 11 communicating with the installation cavity 101 is formed on the stirring rod 1. The first water inlet channel 11 extends spirally in the first direction and has the same spiral direction as that of the stirring blades 12. The filter 2 includes a filter cylinder 21 extending in the vertical direction. The filter cylinder 21 is arranged in the installation cavity 101. The filter cylinder 21 has a tapered cavity extending in the vertical direction inside, and a second water inlet channel 202 communicating the tapered cavity and the installation cavity 101 is formed on the filter cylinder 21. Along the vertical direction, the area of the cross section of the tapered cavity in its radial direction gradually decreases from the first end to the second end of the filter cylinder 21, and the first end of the filter cylinder 21 is located above the second end of the filter cylinder 21 in the vertical direction.

[0088] That is to say, the stirring rod 1 is vertically arranged in the barrel body 20. The rotation of the stirring rod 1 is driven by the wave wheel 30 at this time. The water and clothes in the barrel body 20 are stirred by the rotation of the stirring rod 1. Water enters the tapered cavity through the first water inlet channel 11 and the second water inlet channel 202. Foreign matters in the water flow entering the tapered cavity move towards the second end of the tapered cavity under the action of centrifugal force and its own gravity and accumulate in the tapered cavity. In this way, the filter 2 can be hidden in the stirring rod 1 without arranging the filter 2 on the barrel wall of the barrel body 20, which can save the space of the barrel body 20. Moreover, there is no need to arrange a structure for installing the filter 2 on the barrel body 20, which improves the integrity of the structure of the barrel body 20.
