Description

Technical Field

[0001] This application relates to the field of hair care, and in particular to a filter component, an air intake component, and a hair dryer. Background Technology

[0002] Most hair dryers on the market have a filter at the air inlet to remove larger particles. However, this filter cannot prevent hair clippings and fine dust from entering the air duct. Over time, these particles accumulate near the air inlet, causing blockages and potentially getting tangled in the motor, damaging it and affecting product performance. Therefore, the filter needs to be cleaned or replaced after a period of use.

[0003] Therefore, as disclosed in application number 202180034702.X on March 29, 2021, a hair care device uses a horizontal magnetic attachment to install a filter system at the fluid inlet, thereby filtering the fluid. The filter system can also be magnetically removed for cleaning or replacement. However, this method of magnetically attaching the filter system to the fluid inlet makes the filter system relatively unstable; for example, it can easily fall off if bumped.

[0004] In summary, the technical problem to be solved by this utility model is how to improve the stability of the intermediate layer filter screen.

[0061] The utility model provides a kind of filter assembly 21 of hair dryer 1.

[0062] In the embodiment of the utility model, please refer to Figures 1 to 13 As shown in the figure, the filter assembly 21 of the hair dryer 1 comprises a filter support 110 and a first filter screen 126 fixed on the filter support 110; wherein the filter support 110 forms a fluid passage inside; the filter support 110 is provided with an opening extending along the airflow direction of the fluid passage, so that the filter support 110 forms two free ends 111 in the circumferential direction around the fluid passage, and the two free ends 111 are detachably connected along the airflow direction.

[0063] In the embodiment, the filter support 110 is used to support and / or install the first filter screen 126, and the first filter screen 126 is used to filter the fluid entering the fluid passage. The filter support 110 is hollow in the whole, so that at least one fluid passage is formed inside the filter support 110, so that the fluid including but not limited to air can flow in the fluid passage. The filter support 110 is provided with an opening extending along the airflow direction of the fluid passage, that is, the opening extends along the longitudinal direction of the filter support 110, so that the filter support 110 forms two free ends 111 in the circumferential direction around the fluid passage, that is, the filter support 110 forms left and right two free ends 111, so that the left and right two free ends 111 are detachably connected along the airflow direction, that is, the left and right two free ends 111 are dislocated and moved along the longitudinal direction of the filter support 110, and are detachably connected, so as to realize the detachability of the first filter screen 126, that is, when the first filter screen 126 needs to be replaced or cleaned, the left and right two free ends 111 are dislocated and moved along the longitudinal direction of the filter support 110, so that the left and right two free ends 111 are separated from each other, and then the first filter screen 126 is removed from the filter support 110. Figure 3 Or Figure 4 In the embodiment, the left and right two free ends 111 are dislocated and moved along the upper and lower directions of the filter support 110, so as to realize the detachable connection of the filter support 110, and further realize the detachability of the first filter screen 126.

[0064] In the embodiment, the left and right two free ends 111 are detachably connected along the airflow direction, that is, the left and right two free ends 111 are dislocated and moved, so as to realize the detachability of the first filter screen 126. Compared with the traditional detachable connection along the transverse direction by magnetic attraction, the detachability of the first filter screen 126 is realized, so as to facilitate replacement and cleaning. In addition, the detachable connection by dislocation and movement along the upper and lower directions makes the filter support 110 not easy to fall off, so as to improve the stability of the first filter screen 126, and further improve the service life of the filter assembly 21 and the user's experience.

[0065] In the embodiment, one of the two free ends 111 is provided with a matching lock 112, and the other is provided with a matching groove 113 matched with the matching lock 112, and the matching lock 112 is detachably fixed in the matching groove 113 along the airflow direction.

[0066] Further, one of the left and right free ends 111 is provided with a matching lock 112, and the other is provided with a matching groove 113 matched with the matching lock 112, and the matching lock 112 is detachably installed in the matching groove 113 in the air flow direction, that is, the matching lock 112 moves up and down along the longitudinal direction of the filter support 110 and is detachably installed in the matching groove 113. Specifically, as shown in Figure 3 or Figure 4 in the left free end 111 is the matching lock 112, and the right free end 111 is the matching groove 113 matched with the matching lock 112, and the matching lock 112 on the left free end 111 is matched with the matching groove 113 by moving up and down to realize the detachability of the filter support 110. It should be noted that the matching relationship here is not limited, but is described as an illustration. In fact, the left free end 111 can also be matched with the matching groove 113 on the right free end 111, that is, the left free end 111 can be matched with the matching lock 112 to realize detachability. In addition, it should be noted that the matching lock 112 on the left free end 111 and the matching groove 113 on the right free end 111 are only described for easy understanding, and are not limited. It should be understood that the left free end 111 can also be provided with the matching groove 113, and the right free end 111 can be provided with the matching lock 112.

[0067] The embodiment realizes detachability by the dislocation movement of the matching lock 112 and the matching groove 113 in the air flow direction. Compared with the detachability realized by the magnetic attraction or transverse direction in the prior art, the stability of the present solution is higher.

[0068] In the embodiment, the matching lock 112 and the matching groove 113 are respectively arranged on the opposite wall surfaces of the two free ends 111.

[0069] Further, the matching lock 112 and the matching groove 113 are arranged on the opposite wall surfaces of the two free ends 111, that is, the matching lock 112 is arranged on the right end surface of the left free end 111, and the matching groove 113 is arranged on the left end surface of the right free end 111. It should be noted that the description here is only for easy understanding and is not limited. Other arrangements at least include the matching lock 112 and the matching groove 113 arranged on the outer peripheral wall surface and the inner peripheral wall surface of the two free ends 111. In the embodiment, by arranging the matching lock 112 and the matching groove 113 on the opposite wall surfaces of the two free ends 111, the process strength is improved compared with arranging the matching lock 112 and the matching groove 113 on the outer peripheral wall surface and the inner peripheral wall surface of the two free ends 111, and the appearance is also improved.

[0070] In the embodiment, the matching lock 112 includes a protrusion 114 provided on one of the walls opposite to the two free ends 111, and the protrusion 114 has a limiting surface 131 facing the wall where the protrusion 114 is located; the matching groove 113 has a matching surface 132 which is limited and matched with the limiting surface 131 in the circumferential direction of the fluid passage.

[0071] Further, the matching lock 112 is a protrusion 114 outwardly protruding on one of the walls opposite to the two free ends 111, and the limiting surface 131 of the protrusion 114 includes but is not limited to a gap 115 provided on both sides of the protrusion 114, i.e. as shown in Figure 4 In the embodiment, the matching lock 112 is a protrusion 114 rightwardly protruding on the right end surface of the left free end 111, and gaps 115 are provided on both sides of the protrusion 114. It should be noted that the gaps 115 facing the wall where the protrusion 114 is located are the limiting surfaces 131, and the number of the gaps 115 is not limited, but at least one gap 115 is required, and two gaps 115 are preferred in the embodiment to further improve the stability. The matching groove 113 includes but is not limited to a slot 116 inwardly recessed on the other wall opposite to the two free ends 111 to form a slot 116, and steps 117 matched with the gaps 115 are provided on both sides of the slot 116, i.e. the matching groove 113 is inwardly recessed on the left end surface of the right free end 111 to form a slot 116, and steps 117 matched with the gaps 115 are provided on the end of the slot 116.

[0072] It should be noted that the surface of the step 117 in contact with the limiting surface 131 is the matching surface 132. The specific working principle of the matching lock 112 and the matching groove 113 described above is that when the matching lock 112 and the matching groove 113 are matched, the protrusion 114 of the matching lock 112 is embedded in the slot 116 of the matching groove 113, and after the protrusion 114 of the matching lock 112 is embedded in the slot 116 of the matching groove 113, the steps 117 of the matching groove 113 are embedded in the gaps 115 of the matching lock 112, so as to be limited and matched between the limiting surface 131 and the matching surface 132 in the circumferential direction of the fluid passage. It should be noted that the above description is only an explanation for easy understanding, and is not the only embodiment. For example, the limiting surface 131 and the matching surface 132 can be matched in the way of dovetail groove. In the embodiment, the gaps 115 on the matching lock 112 and the steps 117 in the matching groove 113 can improve the stability of the filter support 110 as a whole compared with the traditional buckle, thereby improving the stability of the filter assembly 21. In the embodiment, the fatigue strength of the matching lock 112 and the matching groove 113 is much higher than that of the traditional buckle, so the service life of the embodiment is much longer than that of the traditional buckle.

[0073] Further, the matching lock 112 and the matching groove 113 form a matching pair, the matching pair extends along the airflow direction of the fluid channel, and the ratio of the extension length of the matching pair to the length of the filter support 110 is 1:20-1:2.

[0074] In the embodiment, the matching lock 112 and the matching groove 113 form a matching pair, the matching pair extends along the airflow direction of the fluid channel, i.e. the matching pair extends along the longitudinal direction of the filter support 110, i.e. the matching pair extends along the upper and lower ends of the filter support 110, so as to increase the matching length between the matching lock 112 and the matching groove 113, and further improve the stability of the filter support 110. It should be noted that when the matching pair extends along the upper and lower ends of the filter support 110, the ratio of the extension length of the matching pair to the length of the filter support 110 is 1:20-1:2. That is, the shortest extension length of the matching pair is 1 / 20 of the length of the filter support 110, so as to ensure that the matching lock 112 and the matching groove 113 can be stably matched, and further ensure the stability of the filter support 110 as a whole. The longest extension length of the matching pair is 1 / 2 of the length of the filter support 110, i.e. the longest extension length of the matching pair does not exceed half of the length of the filter support 110, so as to facilitate disassembly of the filter support 110. In addition, the length of the matching pair as a whole is preferably 1 / 8 of the length of the filter support 110. In the embodiment, the stability of the filter support 110 is further improved by extending the matching pair along the airflow direction. In addition, the length of the matching pair is 1:20-1:2 of the length of the filter support 110, the shortest matching pair still ensures the stability of the filter support 110 as a whole, and the longest matching pair is also convenient to disassemble, and will not damage the filter support 110 due to the movement of the two free ends 111 in a too large range.

[0075] Further, the filter support 110 comprises a first open ring 118, a second open ring 119, and at least two support arms 123; the two support arms 123 both extend along the airflow direction, the two ends of the first open ring 118 and the second open ring 119 are connected by a support arm 123 respectively, so as to form the two free ends 111; the matching lock 112 and the matching groove 113 are arranged on the two support arms 123 respectively.

[0076] In the embodiment, the filter support 110 comprises at least a first open ring 118, a second open ring 119, and at least two support arms 123, the first open ring 118 is arranged at the upper end of the filter support 110, and the second open ring 119 is arranged at the lower end of the filter support 110, the first open ring 118 and the second open ring 119 are annular with openings respectively. The first open ring 118 and the second open ring 119 are arranged at the two ends of the two support arms 123 in the same direction respectively, and the circumferential sides of the two support arms 123 are respectively provided with a free end 111. The two support arms 123 extend along the airflow direction at the two free ends 111 respectively. The first open ring 118 and the second open ring 119 are arranged at the upper and lower ends of the two support arms 123 in the same direction respectively, that is, the first open ring 118 is arranged at the upper end of the two support arms 123, and the second open ring 119 is arranged at the lower end of the two support arms 123.

[0077] In the embodiment, a stabilizing arm 129 can also be included, the upper and lower ends of the stabilizing arm 129 are connected to the first open ring 118 and the second open ring 119 respectively, and the positional relationship between the stabilizing arm 129 and the two support arms 123 includes but is not limited to symmetry, so as to improve the stability of the filter support 110 as a whole. In the embodiment, the matching lock 112 and the matching groove 113 are arranged on the two support arms 123 respectively, compared with the case that the matching lock 112 and the matching groove 113 are arranged on the first open ring 118 and the second open ring 119, the stability of the filter support 110 is improved.

[0078] Further, the first filter screen 126 is arranged in an open ring shape extending around the circumference of the filter support 110, so as to form two movable ends 127 in the circumferential direction of the first filter screen 126; the inner walls of the two support arms 123 are higher than the inner walls of the first open ring 118 and / or the second open ring 119, so as to form first limiting protrusions 124 on the two support arms 123 respectively; when the first filter screen 126 is arranged on the filter support 110, the two movable ends 127 of the first filter screen 126 can abut against the first limiting protrusions 124 on the support arms 123 respectively; and / or, the inner wall of the second open ring 119 is provided with a second limiting protrusion 120, and the second limiting protrusion 120 is provided with a groove 121, and one end of the first filter screen 126 in the axial direction is arranged in the groove 121.

[0079] In the embodiment, the first filter screen 126 is arranged in an open ring shape extending around the circumference of the filter support 110, so as to form two movable ends 127 in the axial direction of the first filter screen 126, that is, the first filter screen 126 can be unfolded and folded in a curved surface, and is unfolded and folded in a curved surface around the circumference of the filter support 110. As shown in FIG. 1, the first filter screen 126 is arranged in an open ring shape extending around the circumference of the filter support 110, so as to form two movable ends 127 in the axial direction of the first filter screen 126, that is, the first filter screen 126 can be unfolded and folded in a curved surface, and is unfolded and folded in a curved surface around the circumference of the filter support 110. Figure 6As shown, the inner wall of the two support arms 123 is higher than the inner wall of the first opening ring 118 and / or the second opening ring 119, thereby forming a first limiting shoulder 124 on both sides of the support arm 123, which is used to limit the two movable ends 127 of the first filter screen 126. When the first filter screen 126 is arranged on the filter support 110, the two movable ends 127 of the first filter screen 126 can abut on the first limiting shoulder 124 of the two support arms 123, respectively.

[0080] Meanwhile, a second limiting shoulder 120 is arranged, which is used to limit one end in the axial direction of the first filter screen 126. Specifically, the second shoulder is arranged on the inner wall of the second opening ring 119, and a groove 121 is arranged on the second limiting shoulder 120, and one end in the axial direction of the first filter screen 126 is arranged in the groove 121, as shown. Figure 9 As shown, the lower end of the first filter screen 126 is arranged in the groove 121. In this embodiment, the first filter screen 126 can be limited by the first limiting shoulder 124 and the second limiting shoulder 120, and the stability of the first filter screen 126 when installed on the filter support 110 is better than when the first limiting shoulder 124 and the second limiting shoulder 120 are arranged. Meanwhile, the groove 121 arranged on the second limiting shoulder 120 further improves the stability of the first filter screen 126 when installed on the filter support 110.

[0081] Further, at least two positioning members 122 for installing the filter assembly 21 are arranged on the inner wall of the second opening ring 119, and the two positioning members 122 are respectively arranged on the two sides of the opening.

In this embodiment, four positioning members 122 are arranged, which are symmetrically arranged on the inner wall of the second opening ring 119. When the cooperating lock 112 is taken out of the cooperating groove 113, the filter support 110 can be moved through the two free ends 111. When the cooperating lock 112 cooperates with the cooperating groove 113, the positioning member 122 installs the filter assembly 21 at the position where filtering is required. In addition, it should be noted that a protrusion (not labeled) is arranged on the positioning member, which is arranged on the end of the positioning member 122, so as to further limit the end of the positioning member 122. In this embodiment, the filter assembly 21 is installed by the positioning member 122, and the disassembly can be synchronized by the disassembly of the cooperating pair, without the need for separate operation, so that the disassembly can be completed.
