[0003] After a long period of air purification, the filter element of the existing household air purification device will be attached with a lot of dirt and cannot continue to purify the air. The filter element needs to be replaced and cleaned regularly. The filter element is inserted into the air purification device and the device needs to be inverted when it is taken out so that the filter element slides down out of the air purification device. The filter element sliding out of the device and falling to the ground is likely to cause dust to fly. Therefore, improvement is needed. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the utility model provides a household air purification device with an easy-to-replace filter element, which solves the problem that when replacing the filter element of the existing household air purification device, the device needs to be inverted so that the filter element slides downward out of the air purification device, and the filter element slides out of the device and falls to the ground, easily causing dust to fly.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a household air purification device with an easy-to-replace filter element, comprising a housing, six groups of fixed hooks are fixedly installed at equal angles on the top of the housing surface, a mounting tube is fixedly installed at the central position of the bottom of the housing, and six groups of ventilation grooves are provided at equal angles on the bottom of the mounting tube surface, a fixing ring is fixedly installed on the top of the mounting tube, and a pull rod is slidably installed inside the mounting tube;

[0006] Six groups of connecting rods are fixedly installed at equal angles on the surface of the bottom end of the pull rod, and the connecting rods are fixedly installed with a top plate through a mounting tube, and a hand-held block is fixedly installed on the top end of the pull rod through a fixing ring, and six groups of filter element bodies are arranged inside the shell on the surface of the mounting tube and the top of the top plate, and a top cover is arranged on the top of the shell.

[0007] As a further solution of the utility model: six groups of limiting convex strips are fixedly installed at equal angles on the surface of the mounting pipe between two groups of adjacent ventilation chutes.

[0008] As a further solution of the utility model: the filter element body is symmetrically provided with limiting grooves at both ends of one side close to the mounting tube, and the limiting grooves correspond to the limiting convex strips.

[0009] As a further solution of the utility model: a mesh plate is fixedly installed on the top of the top cover, a rotating motor is fixedly installed between the top of the top cover and the top of the mesh plate, and a fan impeller is fixedly installed on the output end of the rotating motor through the top of the mesh plate.

[0010] As a further solution of the utility model: six groups of positioning grooves are provided at equal angles on the inner wall at the central position of the bottom of the top cover, and the positioning grooves correspond to the limiting convex strips.

[0011] As a further solution of the utility model: six groups of fixing blocks are fixedly installed at equal angles on the bottom of the top cover surface, and a fixing clamping plate is rotatably installed on the surface of the fixing block, and the fixing clamping plate corresponds to the fixing hook.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The household air purification device with easy-to-replace filter element has a mounting tube, a ventilation chute, a pull rod, a connecting rod and a top plate. When the filter element body is taken out from the inside of the housing for replacement, the pull rod is pulled upward to be withdrawn from the top of the mounting tube, so that the connecting rod moves upward in the ventilation chute, and the top plate is driven to move upward to lift the filter element body upward until the filter element body extends out of the housing, so that the filter element body can be taken out from the inside of the housing for replacement, and dust can be avoided when the filter element body collides with the ground when being taken out of the housing.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a household air purification device with an easy-to-replace filter element, comprising a housing 1, six groups of fixed hooks 6 are fixedly installed at equal angles on the top of the housing 1 surface, a mounting tube 101 is fixedly installed at the central position of the bottom of the housing 1, and six groups of ventilation chutes 102 are provided at equal angles on the bottom of the surface of the mounting tube 101. Due to the ventilation chutes 102, the rotating motor 402 is started to drive the wind impeller 403 to rotate, and the outside air is controlled to pass through the housing 1, the filter element body 3 and the mounting tube 101, and the air flow flows from the ventilation chutes 102 to the wind impeller 403 to circulate and filter the air environment;

[0022] A fixing ring 104 is fixedly installed on the top of the installation tube 101. Due to the fixing ring 104, when the pull rod 2 is pulled, the pull rod 2 slides inside the fixing ring 104, ensuring that the pull rod 2 will not fall over during the pulling process.

[0023] Six groups of limiting ridges 103 are fixedly installed at equal angles on the surface of the mounting tube 101 between two groups of adjacent ventilation grooves 102. Due to the limiting ridges 103, the installation of the filter element body 3 and the top cover 4 is limited and fixed to ensure that there is no misalignment between the mounting tube 101, the filter element body 3 and the top cover 4.

[0024] A pull rod 2 is slidably installed inside the mounting tube 101; six groups of connecting rods 201 are fixedly installed at equal angles on the surface of the bottom end of the pull rod 2, and the connecting rod 201 passes through the mounting tube 101 and is fixedly installed with a top plate 202, and the top end of the pull rod 2 passes through the fixing ring 104 and is fixedly installed with a hand-held block 203. By providing the top plate 202, the pull rod 2 is pulled up to drive the top plate 202 to move up on the surface of the mounting tube 101, and the filter element body 3 is lifted from the inside of the housing 1, so that the filter element body 3 is convenient to replace;

[0025] Six groups of filter element bodies 3 are arranged inside the shell 1 on the surface of the mounting tube 101 and on the top of the top plate 202. Limiting grooves 301 are symmetrically arranged at both ends of one side of the filter element body 3 close to the mounting tube 101, and the limiting grooves 301 correspond to the limiting convex strips 103. Due to the limiting grooves 301, two groups of filter element bodies 3 are adjacently combined, so that the adjacent limiting grooves 301 combination of the two groups of filter element bodies 3 are stuck on the corresponding limiting convex strips 103 surfaces, ensuring that the filter element body 3 will not deflect at will when it is stuck inside the shell 1.

[0026] The top of the housing 1 is provided with a top cover 4. A mesh plate 401 is fixedly installed on the top of the top cover 4, a rotating motor 402 is fixedly installed between the top of the top cover 4 and the top of the mesh plate 401, and an output end of the rotating motor 402 passes through the top of the mesh plate 401 and a fan wheel 403 is fixedly installed. By providing the rotating motor 402 and the fan wheel 403, the rotating motor 402 is started to drive the fan wheel 403 to rotate, so that air can be drawn out through the housing 1, the filter element body 3 and the installation pipe 101, thereby realizing the circulation filtration of the family air environment.

[0027] Six groups of positioning grooves 404 are provided at equal angles on the inner wall at the central position of the bottom of the top cover 4, and the positioning grooves 404 correspond to the limiting convex strips 103. Because of the positioning grooves 404, when the top cover 4 is covered on the top of the outer shell 1, the positioning grooves 404 are stuck on the surface of the corresponding limiting convex strips 103 to ensure that the top cover 4 will not be misaligned when it is fixed on the top of the outer shell 1.

[0028] Six groups of fixed blocks 5 are fixedly installed at equal angles on the bottom of the surface of the top cover 4, and a fixed card plate 501 is rotatably installed on the surface of the fixed block 5, and the fixed card plate 501 corresponds to the fixed hook 6. By providing the fixed card plate 501, when the top cover 4 is correspondingly covered on the top of the outer shell 1, the fixed block 5 corresponds to the fixed hook 6, and the fixed card plate 501 is rotated to make the fixed card plate 501 and the fixed hook 6 tightly connected, so as to facilitate the connection and fixation of the top cover 4 and the outer shell 1.

[0029] The working principle of the utility model is:

[0030] Pull the pull rod 2 upwards to clamp the six groups of filter element bodies 3 on the surface of the installation tube 101, and at the same time make the bottom of the six groups of filter element bodies 3 contact the top of the top plate 202, release the hand-held block 203, and under the action of gravity, the top plate 202 and the filter element body 3 slide down inside the shell 1 to the bottom of the shell 1, and then cover the top cover 4 on the top of the shell 1, so that the positioning groove 404 is clamped on the surface of the corresponding limiting convex strip 103, rotate the fixed clamping plate 501 to clamp with the corresponding fixed hook 6, fix the top cover 4 on the top of the shell 1, start the rotating motor 402 to drive the impeller 403 to rotate, and the air flow in the environment passes through the shell 1, the filter element body 3 and the installation tube 101 and is drawn out by the impeller 403;

[0031] When the filter element body 3 needs to be replaced after a certain period of air filtration, rotate the fixed clamp plate 501 to separate the fixed hook 6, remove the top cover 4 from the top of the outer shell 1, pull the hand-held block 203 upward to drive the pull rod 2 to move upward, so that the pull rod 2 drives the connecting rod 201 and the top plate 202 to move upward, and lift the filter element body 3 from the inside of the outer shell 1 for removal and replacement.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0033] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
