[0027] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application. Figures 2-3 Specifically, the filter base comprises a base 11, a supporting cover 12 movably assembled on the base 11, and a lower cover 13 sealing the lower surface of the base 11, the upper surface of the base 11 is provided with an avoiding hole 11a, the middle part of the supporting cover 12 is provided with a boss, the boss protrudes from the upper surface of the base 11 and can be compressed into the avoiding hole 11a. When the filter is pulled out of the filter cavity, the boss of the supporting cover 12 is pushed out upward from the avoiding hole 11a; when the filter is installed in the filter cavity, the boss of the supporting cover 12 is compressed into the avoiding hole, and at the same time, an opposite force is provided to the filter to tightly press the filter upward.

[0028] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application. Figures 2-3 The central area of the boss of the supporting cover 12 is provided with a light-transmitting part 122, and the light-transmitting part 122 is provided with a UV light-emitting assembly. In this way, when the filter base supports and tightly presses the filter, the inner cavity of the filter can also be subjected to ultraviolet disinfection by the ultraviolet light emitted by the UV light-emitting assembly. Thus, the filter base can not only enhance the sealing performance of the filter end and the filter cavity, but also reduce the bacteria adsorbed on the filter, so as to realize the dual-purpose of the filter base.

[0029] In addition, by arranging the UV light-emitting assembly on the filter base, the UV light-emitting assembly can be checked and maintained at the same time when the filter is replaced and maintained, which is very convenient.

[0030] In addition, by arranging the UV light-emitting assembly on the filter base, the activity space of the supporting cover in the filter base is reasonably utilized, and more available space is reserved for the purifier.

[0031] For better understanding of the improvement of the utility model, the following will be combined with the description of the drawings Figures 3-5 The specific structure of the filter base is further described.

[0032] Referring to Figure 5 , the light-transmitting part 122 is concave downward relative to the upper surface of the boss, forming an inverted conical reflection area 122a. Specifically, in this embodiment, the light-transmitting part 122 is a through hole arranged in the central area of the boss, and the upper side hole of the through hole is chamfered to form a conical reflection area 122a. The UV light-emitting assembly is arranged below the through hole. In this way, when the UV light-emitting assembly emits light from the through hole, part of the ultraviolet light irradiates the inverted conical reflection area, forming diffuse reflection, thereby improving the uniformity of the ultraviolet light to more uniformly irradiate the filter for ultraviolet disinfection.

[0033] In some other embodiments, a functional coating can also be selected to be arranged in the inverted conical reflection area to improve the use experience of the product. For example, a reflective coating is applied in the inverted conical reflection area to improve the diffuse reflection effect of the ultraviolet light and optimize the disinfection effect on the filter; for another example, an anti-UV coating is applied in the inverted conical reflection area to improve the anti-ultraviolet aging performance of the light-transmitting part, avoiding the ultraviolet light from accelerating the aging of the inverted conical reflection area and affecting the service life of the filter base.

[0034] Continuing to refer to Figure 5 , the UV light-emitting assembly 14 includes a PCB board 141, a UV lamp bead 142 arranged on the PCB board 141, and a protective bracket 143 covering the UV lamp bead 142. Since the light-transmitting part 122 is a through hole, the UV lamp bead 142 is in a bare state, and the protective bracket 143 is arranged to avoid the UV lamp bead 142 from being directly exposed. At the same time, the protective bracket 142 can also play a protective role in the installation process of the UV light-emitting assembly 14, avoiding the UV lamp bead 142 from being damaged by colliding with the bottom structure of the support cover 12.

[0035] As a preferred, the protective bracket 143 adopts a flexible bracket. Since the UV light-emitting assembly is arranged on the support cover 12, the support cover 12 is a movable part and will vibrate during the replacement of the filter. In addition, the unevenness of the filter bottom cover or external extrusion can also cause some micro-deformation of the boss area of the support cover 12. If the protective bracket 143 adopts a rigid bracket, the vibration and / or deformation of the support cover 12 will be transmitted to the UV lamp bead 142 from the protective bracket. However, if the flexible bracket is adopted as the protective bracket 143, the flexible bracket can deform to absorb the vibration impact or deformation extrusion, thereby better protecting the UV lamp bead 142.

[0036] In the embodiment, the main body of the flexible support is an elastic silica gel ring 1431, and the inner ring of the elastic silica gel ring 1431 has a groove provided with a light-transmitting sheet 1432 for transmitting ultraviolet light. The light-transmitting sheet 1432 is clamped in the inner ring of the elastic silica gel ring 1431, so that the light-transmitting sheet 1432 is also supported and protected.

[0037] With reference to the foregoing Figures 5-6 In the embodiment, the bottom of the light-transmitting part 122 is provided with a first clamping groove 124 and a second clamping groove 125, and the second clamping groove 125 is located in the first clamping groove 124. The PCB board is clamped in the first clamping groove 124, and the protection support 143 is clamped in the second clamping groove 125. The PCB board 141 and the protection support 143 are fixed respectively, so that the UV light-emitting assembly 14 can be more firm.

[0038] With reference to the foregoing Figure 4 In the embodiment, the convex column 121 of the support cover 12 is chamfered at the part protruding from the avoiding hole 11a. For the convenience of understanding, the state of the support cover 12 when not being extruded by the filter is regarded as the natural state, and the state of the support cover 12 when being extruded by the filter is regarded as the compressed state. The part of the convex column 121 received in the avoiding hole 11a in the natural state is referred to as the first column body 1211, and the part of the convex column 121 protruding from the avoiding hole 11a is referred to as the second column body 1212. The upper end of the second column body 1212 is chamfered at the outer corner, forming an inclined surface 1212a inclined from the outer wall of the second column body 1212 to the center of the second column body 1212. Thus, when the filter is installed, the bottom of the filter is in contact with the inclined surface 1212a, the inclined surface 1212a can convert part of the horizontal thrust into vertical pressure, extrude the support cover 12 to retract into the avoiding hole 11a, avoid the filter, and reduce the resistance when the filter is installed.

[0039] In the embodiment, the convex column 121 is designed as a circular column as a whole, and the upper end of the second column body 1212 is chamfered at the outer corner as a whole, forming a guide circular ring. When the filter is installed, the filter and the hole wall opposite to the filter installation side of the avoiding hole can form a vertical pressure on the convex column 121, so that the support cover 12 can effectively retract into the avoiding hole, and the filter can be more conveniently installed in the filter cavity.

[0040] It should be noted that the convex column 121 is not limited to a circular shape, but can also be other shapes, such as quadrilateral, hexagonal, elliptical, and oval.

[0041] In addition, the part of the convex column 121 protruding from the avoiding hole 11a is chamfered, which is not limited to chamfering the outer corner of the upper end as a whole, but can be chamfered only at the filter installation side and / or chamfered at the opposite side of the filter installation side.

[0042] With reference to the foregoing Figure 4In the embodiment, the bottom of the avoiding hole 11a is provided with a guide ring 11b. The guide ring 11b forms a guide structure with the first base body 1211, so that the support cover 12 is more stable during the ejection and retraction, is not easy to shake, reduces the abnormal sound of the support cover 12 during the movement, and improves the user experience.

[0043] With reference to the foregoing Figure 4 and Figure 6 , the outer periphery of the support cover 12 is provided with four first positioning mounting portions 123, and the base 11 is provided with second positioning mounting portions 11c matched with the four first positioning mounting portions 123. By providing four positioning mounting portions, the positioning and mounting between the support cover 12 and the base 11 are facilitated. Specifically, the first positioning mounting portion 123 is a hole position, and the second positioning mounting portion 11c is a column position, and the assembly positioning of the support cover 12 and the base 11 can be realized by the insertion of the hole position and the column position.

[0044] With reference to the foregoing Figure 4 , the first positioning mounting portion 123 is provided with an elastic member 15, which is compressed when the support cover 12 moves relative to the base 11. Specifically, the elastic member 15 adopts a compression spring, the top of the first positioning mounting portion 123 has a stop ring, the upper end of the compression spring abuts against the stop ring, the second positioning mounting portion 11a is inserted into the first positioning mounting portion 123 from the stop ring and passes out from the lower end of the first positioning mounting portion 123, and the lower end of the compression spring is abutted against the lower cover 13 and is locked in the first positioning mounting portion 123. In this way, when the support cover 12 is extruded by the filter, the stop ring of the first positioning mounting portion 123 compresses the compression spring, so that the support cover 12 is retracted into the avoiding hole 11a; when the filter is taken out, the compression spring upwardly abuts against the first positioning mounting portion, so that the support cover 12 is reset.

[0045] In other embodiments, the elastic member 15 can also be arranged to be stretched when the support cover 12 moves relative to the base 11. For example, the elastic member 15 is arranged between the lower surface of the base 11 and the top of the first positioning mounting portion 123, and when the filter is installed and extrudes the support cover to retract into the avoiding hole, the elastic member is stretched to store energy, and when the filter is taken out, the elastic member is contracted to drive the support cover to reset.

[0046] The above only describes the preferred embodiments of the present application, and is not used as the present application. Any slight modification, equivalent replacement and improvement made according to the technical essence of the present application to the above embodiments shall be included in the protection scope of the technical scheme of the present application.
