At this time, the upper connection port 132 and the lower connection port 141 are locked via a first restricting portion, a second restricting portion, and a third restricting portion described later, thereby connecting the upper cover 130 and the lower cover 140. In addition, the first outer circumferential surface 130a and the second outer circumferential surface 140a are fitted with the convex portion 130b and the concave portion 140b, thereby constituting the outer circumferential surface of the air cleaner 100. In other words, the outer peripheral surface of the air cleaner 100 is configured to be flush with the convex portion 130b and the concave portion 140b. In addition, by including the convex portion 130b and the concave portion 140b, the upper cover 130 and the lower cover 140 can be easily positioned. Therefore, the ease of attachment of the upper cover 130 and the lower cover 140 can be improved.

In addition, the step portion 133 and the step portion 145 mesh with each other. In other words, the portion where the upper cover 130 and the lower cover 140 are in contact has an in-low structure, so that the convex portion 130b can be smoothly slid along the concave portion 140b. In addition, the lower cover 140 includes the ribs 146, whereby the convex portion 130b can be easily positioned when the convex portion 130b and the concave portion 140b are fitted.

The connection of the upper cover 130 and the lower cover 140 will be described using FIGS. 4 to 6. 4 is a side cross-sectional view of the upper cover 130 and the lower cover 140. FIG. 5 is an enlarged front perspective view of a part of the cover 120 showing the first restricting portion. FIG. 6 is an enlarged rear perspective view of a part of the cover 120 showing the second restricting portion.

As shown in Figures 4 and 5, the upper cover 130 and the lower cover 140 are in contact with the part where the convex part 130b and the concave part 140b are fitted, including the first part that restricts the convex part 130b from moving to the outside of the cover 120. Restricted Department.

The direction in which the upper cover 130 and the lower cover 140 are separated refers to a direction opposite to the direction in which the convex portion 130b is inserted into the concave portion 140b. When the upper cover 130 is separated, it is an upward direction, and when the lower cover 140 is separated, it is a downward direction.

The second restricting part is the part where the cover 120 is provided where the upper cover 130 and the lower cover 140 meet, and more specifically, the part where the opening edge 132b of the upper connecting port 132 and the opening edge 141b of the lower connecting port 141 meet . The second restricting portions are provided on both sides of the fitting convex portion 130b and the concave portion 140b in the circumferential direction.

The second restricting portion, as an example, includes: a cover formed on one side, a second engagement protrusion 161 (refer to FIGS. 4 and 6) protruding inward, and a cover formed on the other side to lock the second engagement The protruding second engaging recess 162 (refer to FIGS. 3 and 4). Here, the second locking protrusion 161 is formed in the lower cover 140, and the second engaging recess 162 is formed in the upper cover 130.

As an example, the second engaging protrusion 161 is provided so as to protrude inward from the inner peripheral surface of the opening edge portion 141b of the lower connection port 141. The second engaging recess 162 includes, as an example, a recessed body formed by protruding downward from the opening edge 132b of the upper connecting port 132, and recessed so as to be able to engage the second engaging protrusion 161.

In the above configuration, if the convex portion 130b and the concave portion 140b are fitted, the second engagement protrusion 161 is caught on the edge of the second engagement concave portion 162, and the convex portion 130b can be restricted from being mainly separated from the upper cover 130 and the lower cover 140. Move in direction. As described above, the second restricting portion is provided at the part where the upper cover 130 and the lower cover 140 meet, thereby restricting the separation of the upper cover 130 and the lower cover 140.

As shown in FIGS. 4 and 6, it includes a third restricting portion that is arranged in a circumferential direction with the second restricting portion and restricts movement of the convex portion 130 b to the outside of the cover 120.

The third restricting portion, as an example, includes a third engaging protrusion 171 formed on one cover and protruding toward the other cover, and a third engaging recess formed on the other cover that locks the third engaging protrusion 171 172. Here, the third locking protrusion 171 is formed on the upper cover 130 and the third engaging recess 172 is formed on the lower cover 140.

The third locking protrusion 171 includes the same structure as the first engaging protrusion 151, and is provided to protrude downward from the opening edge 132b of the upper connection port 132. The third engagement recess 172 includes, as an example, a recess formed to protrude inward from the inner peripheral surface of the opening edge portion 141b of the lower connection port 141, and is recessed into a recess body capable of engaging the third engagement protrusion 171.

In the above configuration, if the convex portion 130b and the concave portion 140b are fitted, the third engaging protrusion 171 is locked to the third engaging concave portion 172, thereby mainly restricting from the side portion 141a of the lower connection port 141 to the edge of the opening. The corner formed by the portion 141b moves in the inner and outer directions. As described above, by including the third restricting portion, it is possible to restrict the movement of the above-mentioned corner portion, which is easily shifted, compared with other portions.

Using FIG. 7, the procedure of attaching the cover 120 to the main body 110 will be described. FIG. 7 is a perspective view showing the procedure of attaching the cover 120 to the main body 110. The main body 110 is an insertion port 131 through which the bottom surface (lower end) of the main body 110 is inserted into the upper cover 130. In addition, the main body 110 is locked to the first locking portion 190 of the upper cover 130 to be described later, whereby the main body 110 is attached to the upper cover 130. Then, the convex portion 130b of the upper cover 130 to which the main body 110 is attached is inserted into the concave portion 140b of the lower cover 140 to be fitted. The upper cover 130 and the lower cover 140 are connected via the first restricting portion 150, the second restricting portion 160, and the third restricting portion 170, and the main body 110 is locked to the second locking portion 200 of the lower cover 140, which will be described later, thereby the main body 110 is attached to cover 120 (upper cover 130 and lower cover 140). In the above configuration, the upper cover 130 and the lower cover 140 are configured to be insertable from the same direction with respect to the main body 110. In other words, the upper cover 130 and the lower cover 140 are respectively inserted from the bottom surface side of the main body 110.

As shown in FIGS. 1 and 7, the lower cover 140 includes an opening 143 at a position facing the suction port 111 in a state where the upper cover 130 and the lower cover 140 are combined. As described above, by fitting the convex portion 130b and the concave portion 140b, positioning of the upper cover 130 and the lower cover 140 is performed, whereby the suction port 111 of the main body 110 locked to the upper cover 130 and the suction port 111 formed in the lower cover The openings 143 of 140 are arranged to face each other. That is, it is configured to fit the convex portion 130b and the concave portion 140b to thereby perform positioning of the main body 110 and the opening 143. As a result, air can be efficiently sucked in from the suction port 111 of the main body 110 through the opening 143.

The connection between the main body 110 and the upper cover 130 will be described using FIGS. 8 and 9. FIG. 8 is a side cross-sectional view of the air cleaner 100. As shown in FIG. FIG. 9 is a front cross-sectional view of the upper cover 130 showing the first guide portion 180 and the second guide portion 182. The upper cover 130 includes a first guide portion 180 for determining the direction of the suction port 111 with respect to the convex portion 130b. The main body 110 includes a first guided member 181 guided along the first guide portion 180.

As shown in FIG. 9, the first guide portion 180 includes a pair of guide members 180 a provided on the inner peripheral surface of the upper cover 130 and arranged to face each other with an interval in the circumferential direction. The guide member 180a is provided so as to protrude inward from the inner circumferential surface of the upper cover 130. The pair of guide members 180a are formed to extend the gap (width) facing the insertion port 131 (upward). The first guide portions 180 are respectively provided at positions opposite to the inner peripheral surface of the upper cover 130. More specifically, the first guide 180 is provided on the front side and the back side, respectively. The first guided member 181 is a protrusion protruding from the outer surface of the body 110 toward the outside. The first guided member 181 corresponds to the position of the first guide 180, and is provided on the front side and the back side of the main body 110, respectively.

In the above configuration, when the main body 110 is inserted into the insertion port 131 of the upper cover 130, the first guided member 181 is guided to the upper portion of the first guide part 180. And, as the first guided member 181 advances downward to between the pair of guide members 180a, the first guided member 181 corrects the course by the pair of guide members 180a. As a result, the main body 110 is inserted in a predetermined direction with respect to the upper cover 130. The predetermined direction here refers to a direction in which at least the suction port 111 does not face the convex portion 130b. As described above, even if the direction of the suction port 111 with respect to the convex portion 130b is shifted inside the upper cover 130 during insertion, the main body 110 can be guided to a predetermined direction. That is, the first guide portion 180 determines the orientation of the suction port 111 with respect to the convex portion 130b.

In addition, although the first guide 180 is preferably provided as a pair facing the inner peripheral surface of the upper cover 130, it is not limited to this, and only one may be provided on the inner peripheral surface of the upper cover 130.

In addition, the cross-sectional shape of the upper cover 130 is configured as a polygonal shape with corners (in the present embodiment, it is substantially rectangular), so that when the main body 110 is inserted from the insertion port 131, it is possible to reduce the amount of interference with respect to the convex portion 130b. The direction of the suction port 111 is inserted into the wrong direction. In addition, the upper end portions of the upper cover 130 and the main body 110 are inclined so as to be lowered from the back side toward the front side, which can further reduce the wrong direction of inserting the suction port 111 with respect to the convex portion 130b. Thereby, positioning with the main body 110 and the upper cover 130 can be easily performed.

In addition, although the cross-sectional shape of the upper cover 130 is preferably a polygonal shape with corners (in this embodiment, it is substantially rectangular), it is not limited to this, and may be, for example, a cylindrical shape. In addition, although the shape of the lower cover 140 is preferably a cylindrical shape, it is not limited to this, and it may be a shape embedded in a beverage holder.

As shown in FIGS. 8 and 9, the upper cover 130 includes a first locking portion 190 for determining a position relative to the main body 110 of the upper cover 130. The first locking portion 190 locks the first guided member 181. The first locking portion 190 is, as an example, a protrusion formed by protruding inward from the inner peripheral surface of the upper cover 130. As an example, the first locking portion 190 is formed between a pair of guide members 180a constituting the first guide portion 180 at a portion (lower end portion) where the opposing interval of the pair of guide members 180a is narrow.

In the above configuration, the main body 110 is inserted from the insertion port 131 of the upper cover 130 and guides the first guided member 180 downward along the first guide portion 180. In addition, the first guided member 181 straddles the first locking portion 190, whereby the main body 110 can be locked with the orientation of the suction port 111 with respect to the upper cover 130 (convex portion 130b) in a predetermined direction. .

As shown in Fig. 9, the upper cover 130 further includes a second guide portion 182 for determining the direction of the suction port 111 with respect to the convex portion 130b below the first guide portion 180. The main body 110 includes a second guided member 183 guided along the second guide portion 182.

The second guide portion 182, similarly to the first guide portion 180, includes a pair of guide members 182a. The pair of guide members 182a are configured such that the width of the upper end portion is wider than that of the pair of guide members 180a. The second guide portion 182 is provided only on the back side of the inner peripheral surface of the upper cover 130. The second guided member 183, like the first guided member 181, is a protrusion protruding from the outer surface of the main body 110 toward the outside. The second guided member 183 corresponds to the position of the second guide 182 and is provided on the back side of the main body 110.

The second guide portion 182 is formed in the inner peripheral surface of the upper cover 130 compared to the first guide portion 180, and the width of the opposed interval is small (in this embodiment, the lower end portion) . Therefore, compared with the case where only the first guide portion 180 is provided, since the second guided member 183 can be guided along the second guide portion 182 before the first guide portion 180 when the main body 110 is inserted, the second guided member 183 can be efficiently guided. The ground restricts the displacement of the body 110 from a predetermined direction relative to the upper cover 130.

In addition, by providing the first locking portion 190 between the first guide portion 180, the main body 110 can be locked in the upper side where a gap is likely to occur between the upper cover 130 and the main body 110. Therefore, the upper cover 130 and the main body 110 can be prevented from shaking.

Using FIG. 8, the connection between the main body 110 and the lower cover 140 will be described. The lower cover 140 includes a second locking portion 200 that locks the body 110 at a position relative to the main body 110 of the lower cover 140, more specifically, at a position (height) where the suction port 111 and the opening portion 143 face each other. The second locking portion 200 locks the locking protrusion 201 provided on the main body 110.

The second locking portion 200 includes an opening for locking the locking protrusion 201 as an example.
