[0002] With the rapid development of printing technology, 3D printing technology for printing three-dimensional physical objects has been increasingly applied. The wax-type 3D printer belongs to a kind of wax material additive manufacturing machine. It uses phase-change wax as the printing material, sprays the wax heated to a high temperature onto the printing platform, and builds a model by stacking layer by layer. Due to the advantages of high precision and smooth surface of the wax-sprayed 3D printing model, the wax-sprayed 3D printer is widely used in manufacturing industries such as jewelry, aerospace, and engines.

[0003] In the prior art, in order to keep the inside of the machine cavity of the wax-sprayed 3D printer clean, a large air circulation device at the bottom is designed to directly suck the wax material dust inside the cavity into the purification box, and the purification effect is achieved by regularly replacing or cleaning the large filter screen. However, in actual use, due to the large accumulation amount of wax material dust in the cavity, the filter screen is often prone to quickly clog, and due to the lack of a prompt mechanism for timely replacement, the purification effect is poor. At the same time, the components inside the cavity are often affected by dust pollution and their normal use is affected. In addition, the air circulation device itself is also prone to adsorbing dust and is not easy to clean or replace, further increasing the difficulty of maintenance. Summary of the Utility Model

[0037] The following will describe in detail some embodiments of the present utility model with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0038] In the prior art, in order to keep the inside of the machine cavity clean, a large air circulation device at the bottom is designed to directly suck the wax material dust inside the cavity into the purification box, and the purification effect is achieved by regularly replacing or cleaning the large filter screen. However, in actual use, due to the large accumulation amount of dust in the cavity, the filter screen is often prone to quickly clog, and due to the lack of a prompt mechanism for timely replacement, the purification effect is poor. At the same time, the components inside the cavity are often affected by dust pollution and their normal use is affected. In addition, the air circulation device itself is also prone to adsorb dust and is not easy to clean or replace, further increasing the difficulty of maintenance.

[0039] In view of this, see Figures 1 to 6, the purification component 100 provided by the embodiment of the present utility model includes a filter net 120, a heating device 130 and a control device (not shown in the figure). The filter net 120 has an air inlet side and an air outlet side. In some embodiments, the filter net 120 is made of high-efficiency materials and has a fine pore structure, which can capture tiny dust particles and ensure the cleanliness of the air.

[0040] An air volume sensor 140 for monitoring the air volume is provided on the air outlet side. The air volume sensor 140 accurately monitors the air volume on the air outlet side and feeds it back to the control device in real time. The heating device 130 can heat the filter net 120. Both the air volume sensor 140 and the heating device 130 are electrically connected to the control device. When the control device receives that the air volume collected by the air volume sensor 140 is lower than a preset threshold, the control device automatically activates the heating device 130 to keep the filter net 120 unobstructed.

[0041] By cleverly arranging the air volume sensor 140 on the air outlet side, the purification component 100 of the present utility model can monitor the ventilation volume of the purification component 100 in real time. Once the air volume sensor 140 detects that the ventilation volume is lower than the preset threshold, the control device will respond intelligently and automatically activate the heating device 130 to heat the filter net 120. This heating process aims to make the wax dust reach the molten state and then firmly adsorb on the filter net, thereby effectively preventing the filter net 120 from losing its effectiveness due to rapid blockage and ensuring the continuous and efficient operation of the purification component 100. The heating device 130 can heat the dust attached to the filter net 120, thereby melting and reducing the volume, avoiding the situation where the dust accumulates on the filter net 120 and blocks the filter net 120, affecting the filtering effect.

[0042] In an alternative solution of the embodiment of the present utility model, the heating device 130 is a heater, and the heater is electrically connected to the control device; or, the heating device 130 is a heating wire wound around the filter net 120, and the heating wire is electrically connected to the control device.

[0043] Specifically, the heating device 130 is a heater, and the heater is electrically connected to the control device. By controlling the start and stop of the heater through the control device, the working state of the heater can be flexibly controlled. There is no need to manually or adjust complex mechanical structures to control the start and stop of the heater, which simplifies the operation process and reduces the usage difficulty. Since the switching process is automated, the need for manual intervention is reduced, thereby saving operation time and improving work efficiency. Or, please refer to Figure 5, the heating device 130 is a heating wire wound around the filter net 120. The heating wire is electrically connected to the control device. By controlling the start and stop of the heating device 130 through the control device, the working state of the heating wire can be flexibly controlled. There is no need to manually or adjust a complex mechanical structure to control the start and stop of the heating wire, which simplifies the operation process and reduces the usage difficulty. Since the switching process is automated, the need for manual intervention is reduced, thus saving operation time and improving work efficiency.

[0044] The heating device 130 can be a heating wire directly installed on the filter net 120 or an independently controlled heater. In either form, the heating device 130 can quickly respond to the instructions of the control device and effectively heat the filter net 120. These heating devices are all electrically connected to the control device, allowing the control device to flexibly control their working states.

[0045] In an alternative solution of the embodiment of the present utility model, the purification component 100 further includes a temperature sensor 150. The temperature sensor 150 is arranged on the air outlet side and is electrically connected to the control device.

[0046] Specifically, please refer to Figure 4 , in order to further improve the safety and energy efficiency of the system, the purification component 100 further includes a temperature sensor 150. The temperature sensor 150 is electrically connected to the control device and can monitor the temperature of the heating device 130 in real time. Thus, through the temperature sensor 150, it can be detected whether the temperature of the heating device 130 exceeds the temperature threshold preset in the control device. When the preset temperature threshold is exceeded, the control device will immediately stop the operation of the heating device 130 to avoid energy waste and ensure system safety. By monitoring the temperature in real time, the control device controls the start and stop of the heating device 130, and can flexibly control the working state of the heating device 130. Further, the temperature sensor 150 is arranged on the air outlet side. The temperature sensor 150 is arranged on the air outlet side, and can better monitor the dust heating state on the filter net 120. There is no need to manually or adjust a complex mechanical structure to control the start and stop of the heating device 130, which simplifies the operation process and reduces the usage difficulty, bringing a more convenient and efficient usage experience to the operator.

[0047] By integrating the air volume sensor 140 and the temperature sensor 150 on the air outlet side of the purification component 100 of the present utility model, the ventilation volume and temperature of the purification component 100 can be monitored in real time. Once the air volume sensor 140 detects that the ventilation volume is lower than the preset threshold, the control device will respond intelligently and automatically activate the heating device 130 to heat the filter net 120. When the heating temperature reaches the preset threshold, the heating device 130 is turned off, thus avoiding energy waste.

The partition plate 180 covers the air outlet side, and the air circulation device 170 is installed on the partition plate 180, and the air inlet end of the air circulation device 170 faces the filter net 120.

[0055] Specifically, the air circulation device 170 is installed on the partition plate 180, which facilitates the installation of the air circulation device 170 and optimizes the installation position of the fan. The air inlet end of the air circulation device 170 faces the filter net 120, so as to promote the air in the purification component 100 to move in a preset direction, thereby completing the purification of the air and improving the purification efficiency.

[0056] In an alternative embodiment of the present utility model, please refer to Figure 4 and Figure 5 , the purification component 100 further includes a secondary filtration device 190. The secondary filtration device 190 includes a purification cotton 192, and the dust pollutants can be prevented from entering outside the printing chamber through the purification cotton 192.

Further, a plurality of ventilation holes are provided on both the purification cover 191 and the purification lid 193, so as to facilitate the entry and exit of gas.

The purification cover 191 and the purification lid 193 protect the purification cotton 192 and ensure its optimal working state, while maintaining the shape and filtration effect of the purification cotton 192.

[0060] In an alternative embodiment of the present utility model, the purification assembly 100 further includes an alarm device (not shown in the figure).

[0061] The present utility model further provides a wax material additive manufacturing machine, which includes a box body (not shown in the figure) and the above-mentioned purification assembly 100. The box body has a receiving cavity, and the purification assembly 100 is disposed at the top of the receiving cavity.

[0062] In the wax material additive manufacturing machine of the present utility model, by providing the purification assembly 100 at the top, it can ensure that the air in the box body is purified during the air circulation process, providing an efficient, environmentally friendly and safe manufacturing solution.

[0063] Please refer to Figures 1 to 6 , the working process of the present utility model is as follows:

[0064] Fix the air circulation device 170 on one side of the cavity to be purified on the partition board 180. The heating device 130, the air volume sensor 140 and the temperature sensor 150 are fixed on the fixing seat 160, on one side of the air circulation device 170. The detachable cover 110 and the filter net 120 are made into a component and placed in the air inlet direction. The purification cover 191, the purification cotton 192, and the purification cover 191 shell are made into a component in the air outlet direction outside the cavity.

[0065] When the machine is working, the air circulation device 170 is turned on, and the air flow with wax powder goes from the cavity to the outside of the cavity, and the powder is filtered out by the filter screen 120. The air volume decreases. When the air volume sensor 140 detects that the air volume decreases to a certain value, it is confirmed that the powder deposition on the filter screen 120 is saturated. The heating device 130 starts to heat until the wax material reaches the molten state and adsorbs on the filter screen 120, and the filter screen becomes unclogged and continues to filter. When the temperature sensor 150 detects that the temperature is too high, the heating stops. The dust pollutants that slip through the net can be filtered again by the purification cotton 192 that does not require heating to prevent pollution outside the cavity.

[0066] Under the action of the air volume sensor 140 and the temperature sensor 150, the air volume and temperature are adjusted so that the purification work can be carried out for a long time. When the air volume sensor 140 detects that the air volume cannot be adjusted, it is confirmed that the filter screen 120 has reached the saturated state, and the operator is prompted to replace the filter screen 120 and the purification cotton 192.

[0067] A purification component 100 is arranged on the top of the wax additive manufacturing machine, and the air circulation device 170, the purification cotton 192, the filter screen 120, the heating device 130, the temperature sensor 150 and the air volume sensor 140 are assembled into a component. During operation, the air volume sensor 140 and the temperature sensor 150 can be used to detect the ventilation volume and temperature, and the filter screen is repeatedly heated to make the wax dust reach the molten state and adsorb on the filter screen. When the limit of the filter screen is reached, it can be detected whether the filter screen or the filter cotton needs to be replaced or cleaned. The purification effect inside the cavity is enhanced, and the parts and components of the machine are protected.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
