The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0029] Embodiment 1

[0030] Refer to Figures 1 to 7 , which is the first embodiment of the present utility model. This embodiment provides a heater with a detachable filter at the heat dissipation opening. The heater with a detachable filter at the heat dissipation opening includes a main body assembly 100 and a disassembly assembly 200. Through the cooperation of the two, when it is necessary to disassemble the filter at the heat dissipation opening of the heater, the separating member 201 and the supporting member 202 can cooperate with each other, so that dust, hair and other impurities brought in when the fan 201b rotates adhere to the surface of the filter 201c, thereby avoiding the accumulation of dust, hair and other impurities on the fan 201b, and the filter 201c can be taken out of the heater through the separating member 201, and the surface of the filter 201c can be cleaned, so that the filter 201c can be used repeatedly.

[0031] Specifically, the main body assembly 100 includes a heater 101, an air outlet 102, and a base 103. The air outlet 102 is arranged on one side of the heater 101, and the base 103 is fixed to the bottom of the heater 101.

[0032] The heater 101 is used to heat the air, providing a warm environment indoors so that people can maintain a comfortable temperature at home. The air outlet 102 is used to discharge the air heated by the heater 101, enabling the hot air to be evenly dispersed to all corners of the room, thus achieving the effect of overall temperature rise. The heater 101 and the air outlet 102 are prior arts and will not be elaborated here. The base 103 is used to fix the position of the heater 101, thereby ensuring that the heater 101 will not shake during use and can maintain stability.

[0033] The disassembly component 200 is disposed inside the heater 101 and includes a separating member 201 and a supporting member 202. The separating member 201 is disposed inside the heater 101, and the supporting member 202 is located on one side of the separating member 201.

[0034] The separating member 201 is fixed inside the heater 101 to ensure that the overall position of the separating member 201 will not shift. The separating member 201 is used to disassemble or fix the filter screen of the heat dissipation port, thereby ensuring that the filter screen of the heat dissipation port can be replaced or cleaned. Moreover, the separating member 201 and the supporting member 202 cooperate with each other. When the filter screen is disassembled by the separating member 201, the position of the supporting member 202 can be driven simultaneously, enabling the supporting member 202 to release the support for the filter screen, so that the filter screen can be taken out of the heater 101, ensuring that the filter screen can be replaced or cleaned.

[0035] Specifically, the separating member 201 includes a shielding plate 201a and a fan 201b. The shielding plate 201a is fixed inside the heater 101, and the fan 201b is fixed inside the shielding plate 201a.

[0036] The shielding plate 201a is used to block impurities such as dust and hair in the air, ensuring that dust, hair and other impurities do not enter the interior of the heater 101 and preventing them from affecting the normal use of the air outlet 102. The fan 201b is used to dissipate heat from the heater 101, ensuring that the temperature inside the heater is controlled within a safe range and avoiding safety accidents caused by overheating.

[0037] Specifically, the separating member 201 further includes a filter screen 201c and a slide rail 201d. The filter screen 201c slides on the surface of the shielding plate 201a, and the slide rail 201d is fixed inside the heater 101.

[0038] Currently, the filter screen 201c is in an uninstalled and unfixed state. The filter screen 201c is used to block impurities such as dust and hair brought in by the rotation of the fan 201b, preventing impurities such as dust and hair in the air from entering the interior of the heater through the heat dissipation port, and preventing the accumulation of dust and hair on the fan blades of the fan 201b, thereby affecting the heat dissipation effect of the fan 201b. The slide rail 201d is used to ensure the moving position of the separating member 201, so as to ensure that when the separating member 201 moves, it will not deviate, and ensure that the separating member 201 can release the fixation of the filter screen 201c.

[0039] Specifically, the separating member 201 further includes a sliding plate 201e and a connecting block 201f. The sliding plate 201e slides on the surface of the slide rail 201d. A first moving groove T is provided inside the sliding plate 201e. The first moving groove T can be in contact with the separating member 201. The connecting block 201f is fixed to one side of the sliding plate 201e.

[0040] The sliding plate 201e is used to drive the separating member 201 to move, so as to ensure that the separating member 201 can release the restriction on the filter screen 201c. And a first moving groove T is provided inside the sliding plate 201e, so as to ensure that the separating member 201 can move in the first moving groove T, enabling the filter screen 201c to be taken out of the heater. The connecting block 201f is used to drive the sliding plate 201e back to its original position, so as to ensure that the sliding plate 201e can drive the filter screen 201c to move next time.

[0041] Embodiment 2

[0042] Refer to Figures 4 to 6 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0043] Specifically, the separating member 201 further includes a fixing block 201g and a compression spring 201h. The fixing block 201g is fixed inside the heater 101. One end of the compression spring 201h is fixed to one side of the fixing block 201g, and the other end of the compression spring 201h is fixed to one side of the connecting block 201f.

[0044] The fixing block 201g is used to fix the position of the compression spring 201h, so as to ensure that the compression spring 201h will not deviate, enabling the compression spring 201h to control the position of the sliding plate 201e through the connecting block. The compression spring 201h is currently in a natural state and is used to control the position of the sliding plate 201e, ensuring that the sliding plate 201e can release the restriction or fixation on the position of the filter screen 201c again, so as to facilitate the operator to take out the filter screen 201c from the heater.

[0045] Specifically, the separating member 201 further includes a guiding block 201i, a positioning block 201j, and a limiting block 201k.

[0046] The guiding block 201i can cooperate with the positioning block 201j to ensure that when the sliding plate 201e moves, the separating member 201 can move according to the positions of the guiding block 201i and the positioning block 201j through the second moving groove Y, so as to ensure that the separating member 201 falls into the second moving groove Y and the separating member 201 can be fixed by the positioning block 201j. One side of the limiting block 201k is lower than the positioning block 201j by a certain part, so as to ensure that when the sliding plate 201e moves again, the separating member 201 can be in contact with the limiting block 201k, thereby controlling the separating member 201 to be released from the restriction of the positioning block 201j and enabling the sliding plate 201e to move.

[0047] Specifically, the separating member 201 further includes a placing block 201l, a supporting block 201m, and a moving rod 201n. The placing block 201l is fixed within the heater 101, the supporting block 201m is fixed within the placing block 201l, the moving rod 201n is rotatably connected within the supporting block 201m, and the moving rod 201n can slide within the sliding plate 201e.

[0048] The placement block 201l is used to fix the position of the support block 201m, thereby ensuring that the support block 201m will not shift. The support block 201m is used to support the position of the moving rod 201n, enabling the moving rod 201n to move within the sliding plate 201e, thereby ensuring that the position of the sliding plate 201e can be restricted by the moving rod 201n. A shrinkage block is provided inside one end of the moving rod 201n, thereby ensuring that the moving rod 201n can move inside the sliding plate 201e. The moving rod 201n is used to limit the position of the sliding plate 201e, thereby ensuring that the filter screen 201c can be released from the restriction and the filter screen 201c can move. When the sliding plate 201e moves, the moving rod 201n can come into contact with the guiding block 201i and the positioning block 201j, thereby enabling the moving rod 201n to move between the guiding block 201i and the positioning block 201j, ensuring that the moving rod 201n can move to the top of the positioning block 201j, thereby fixing the position of the sliding plate 201e through the positioning block 201j. And when the sliding plate 201e moves again, through the blocking of the limiting block 201k, the moving rod 201n can release the restriction on the positioning block 201j, ensuring that the moving rod 201n can move when the sliding plate 201e moves, thereby enabling the moving rod 201n to release the restriction on the sliding plate 201e through the positioning block 201j and enabling the sliding plate 201e to move.

[0049] Embodiment 3

[0050] Refer to Figure 6 and Figure 7 , which is the third embodiment of the present utility model, and this embodiment is based on the first two embodiments.

[0051] Specifically, the support member 202 includes a positioning plate 202a, a clamping block 202b, and a moving plate 202c. The positioning plate 202a is fixed to one side of the sliding plate 201e, the clamping block 202b is fixed to one side of the positioning plate 202a, and the moving plate 202c is rotatably connected to the clamping block 202b.

[0052] The positioning plate 202a is used to drive the sliding plate 201e to move, thereby ensuring that the sliding plate 201e can move simultaneously with the positioning plate 202a when the positioning plate 202a is squeezed by the filter screen 201c. The clamping block 202b is used to fix the position of the moving plate 202c, thereby ensuring that the moving plate 202c can move together with the positioning plate 202a. The moving plate 202c is used to drive the support member 202 to move, thereby fixing or releasing the restriction on the position of the filter screen 201c.

[0053] Specifically, the support member 202 further includes a support plate 202d and a sliding rod 202e. The support plate 202d is fixed inside the heater 101. A moving track V is provided on one side of the support plate 202d. The sliding rod 202e slides within the moving track V, and the sliding rod 202e is fixed to one side of the moving plate 202c.

[0054] The support plate 202d is used to limit the moving distance of the sliding plate 201e, thereby ensuring that the sliding plate 201e does not exceed the slide rail 201d when it moves. And the sliding rod 202e is limited by the moving track V on one side of the support plate 202d, so that the sliding rod 202e can control the position of the moving plate 202c, and the moving plate 202c can be clamped and fixed with the filter screen 201c.

[0055] Specifically, the support member 202 further includes a storage block 202f, a limiting ring 202g, a pushing block 202h, and a compression spring 202i. The storage block 202f is fixed inside the moving plate 202c. The limiting ring 202g is fixed inside the storage block 202f. The pushing block 202h slides within the storage block 202f. One end of the compression spring 202i is fixed inside the storage block 202f, and the other end of the compression spring 202i is fixed to the bottom of the compression spring 202i.

[0056] The storage block 202f is used to fix the position of the limiting ring 202g, ensuring that the limiting ring 202g can limit the pushing block 202h, so as to ensure that the pushing block 202h can squeeze the filter screen 201c, so that the filter screen 201c can be in close contact with the rear shell of the heater 101. In this way, during long-term use, the filter screen 201c will not become loose, and the filter screen 201c can effectively block impurities such as dust and hair in the air, so as to ensure that the fan blades of the fan 201b remain clean. The compression spring 202i is currently in a compressed state, so as to squeeze the position of the pushing block 202h, so that the pushing block 202h can always be in contact with the limiting ring 202g, ensuring that the pushing block 202h is always in a pushing state. Ensure that when the moving plate 202c moves, the pushing block 202h can contact the filter screen 201c, so that the filter screen 201c can be in close contact with the rear shell of the heater 101, ensuring that the filter screen 201c will not become loose during long-term use. A sealing ring is provided at the contact position between the filter screen 201c and the rear shell of the heater 101, thereby ensuring the sealing performance of the contact position between the filter screen 201c and the rear shell of the heater 101.

[0057] When it is necessary to disassemble the filter screen at the heat dissipation outlet of the heater during use, first press the filter screen 201c, so that the filter screen 201c drives the positioning plate 202a to move a short distance. When the positioning plate 202a moves a short distance, it can drive the sliding plate 201e to move at the same time, so that the moving rod 201n in the sliding plate 201e contacts the limiting block 201k, and through the blocking of the moving rod 201n by the limiting block 201k, the restriction of the positioning block 201j by the moving rod 201n is released. At this time, cancel the pressing of the filter screen 201c, and the compression spring 201h will drive the sliding plate 201e to move, drive the positioning plate 202a to move through the sliding plate 201e, and make the positioning plate 202a push the filter screen 201c out of the heater interior. When the restriction of the positioning block 201j by the moving rod 201n is released, the sliding plate 201e will drive the positioning plate 202a to move. When the positioning plate 202a moves, it can drive the moving plate 202c to move through the clamping block 202b, and ensure the moving position of the moving plate 202c through the sliding rod 202e on one side of the moving plate 202c, so as to ensure that the moving plate 202c can fix the filter screen 201c again next time. And when the moving plate 202c moves, the storage block 202f in the moving plate 202c will cancel the restriction on the filter screen 201c, so that the pushing block 202h releases the restriction on the filter screen 201c, so that the filter screen 201c can be taken out of the heater, which is convenient for cleaning or replacement, so as to ensure the blocking of the fan 201b, keep the fan blades of the fan 201b clean, ensure that it will not affect the heat dissipation effect of the fan 201b on the heater, and avoid safety accidents caused by overheating of the heater.
