DETAILED DESCRIPTION

[0024] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0025] In the present disclosure, unless otherwise stated, directional words such as "upper, lower, vertical" are defined according to the direction of the grease removal device, and "inside, outside" are defined according to the contour of the corresponding component itself. Terms such as "first, second" and the like used in the present disclosure are used to distinguish one element from another element and do not have order and importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0026] See also Figures 1 to 3 , a grease impurity removal device is provided in an embodiment of the present disclosure, and the grease impurity removal device may include a housing 100, an impurity removal mechanism 200 and a heating element 300. The housing 100 may have an oil inlet 110 and an oil outlet 120 that are relatively arranged. The impurity removal mechanism 200 may be installed in the housing 100 at a position close to the oil inlet 110 to remove impurities in the grease. The heating element 300 may be arranged in the housing 100 to heat the grease after impurities are removed, and the heating element 300 may be installed in the housing 100 at a position close to the oil outlet 120, and the close here means that the heating element 300 is closer to the oil outlet 120 than the oil inlet 110.

[0027] In the related art, after the grease to be cleaned enters the grease cleaning device, it is first heated, and some impurities may dissolve in the grease after heating, so the cleaning effect is not good. In this embodiment, through the above technical solution, the cleaning mechanism 200 is close to the oil inlet 110, and the heating element 300 is close to the oil outlet 120. The grease enters the housing 100 through the oil inlet 110. The grease is first filtered and cleaned by the cleaning mechanism 200. After the grease has been fully cleaned and filtered, the grease is heated by the heating element 300 to the temperature required by the hydraulic device. This avoids the poor cleaning effect of the grease after heating, and ensures that the impurities inside the grease can be completely removed before the grease is "reused".

[0028] In one embodiment, see Figures 1 to 3 The impurity removal mechanism 200 is detachably mounted on the housing 100. It is convenient for the user to maintain or replace the impurity removal mechanism 200, thereby improving the impurity removal effect of the grease.

[0029] For further information, see Figure 2 The impurity removal mechanism 200 may include a mounting plate 210, a magnet column 220 and an oil filter plate 230. The mounting plate 210 may be detachably connected to the housing 100. The magnet column 220 may be connected to the mounting plate 210 to absorb metal in the grease. The oil filter plate 230 may be sleeved on the magnet column 220 to filter impurities in the grease.

[0030] By detachably mounting the mounting plate 210 on the housing 100 , it is convenient for the user to remove the magnet column 220 and the oil filter plate 230 directly or indirectly mounted on the mounting plate 210 , thereby facilitating maintenance or replacement of the magnet column 220 and the oil filter plate 230 , thereby improving the grease removal effect.

[0031] For further information, see Figure 2 The number of the oil filter plates 230 can be multiple, and they are spaced apart and sleeved on the magnet column 220. By providing multiple oil filter plates 230, the effect of grease filtering impurities can be increased.

[0032] In one embodiment, see Figure 2 The grease removal device may further include a connector 410, which may penetrate the mounting hole of the mounting plate 210 and may be threadedly connected to the mounting hole of the housing 100 to mount the mounting plate 210 on the housing 100. The connector 410 may be a bolt or a screw. By providing the connector 410, the mounting plate 210 and the housing 100 may be detachably connected, which is convenient for users to maintain or replace the impurity removal mechanism 200.

[0033] In one embodiment, see Figure 3The grease removal device may further include a first oil baffle 420 that divides the housing 100 into a first chamber 130 and a second chamber 140. The oil inlet 110 may be connected to the first chamber 130 and the impurity removal mechanism 200 may be disposed in the first chamber 130. The oil outlet 120 may be connected to the second chamber 140 and the heating element 300 may be disposed in the second chamber 140. The first oil baffle 420 may be provided with a through hole 421, so that the grease in the first chamber 130 may enter the second chamber 140 through the through hole 421. The first oil baffle 420 may prevent the grease from quickly entering the second chamber 140, thereby ensuring that the impurity removal mechanism 200 has more time to remove all impurities in the grease.

[0034] For further information, see Figure 3 The through hole 421 is arranged in the upper part of the first oil baffle plate 420 (i.e., the part of the first oil baffle plate 420 close to the top of the shell 100), which can extend the time for the grease in the first chamber 130 to enter the second chamber 140, ensuring that the impurity removal mechanism 200 can remove all impurities in the grease.

[0035] In one embodiment, see Figures 1 to 3 The heating element 300 is a heating rod extending into the second chamber 140. The heating rod is a constant temperature heating rod. The grease in the second chamber 140 is heated by the heating rod so that the temperature of the grease reaches the required temperature of the hydraulic device.

[0036] In one embodiment, see Figure 3 The grease removal device may further include a second oil baffle plate 430 detachably mounted in the first chamber 130, that is, the second oil baffle plate 430 has an installed state and a non-installed state. In the installed state, the second oil baffle plate 430 may be installed in the first chamber 130, and at this time, it may block the grease flowing to the first oil baffle plate 420.

[0037] It is understandable that when the grease contains a large amount of impurities, the second oil baffle 430 is inserted into the first chamber 130 to prevent the grease from entering the second chamber 140 through the through hole 421, thereby extending the time for the grease in the first chamber 130 to enter the second chamber 140, ensuring that the impurity removal mechanism 200 has more time to remove all impurities in the grease, thereby improving the impurity removal effect of the grease.

[0038] This embodiment does not limit the installation method of the second oil baffle plate 430. For example, a through hole for the second oil baffle plate 430 can be opened on the shell 100. In order to prevent grease from flowing out of the through hole during the removal of the second oil baffle plate 430, the through hole can be opened at the top of the shell 100. In addition, an openable and closable baffle can also be set at the through hole.

[0039] In one embodiment, see Figures 1 to 4 The grease removal device may further include a liquid level detection mechanism 500 disposed in the second chamber 140. The liquid level detection mechanism 500 may be used to detect the amount of grease in the second chamber 140 to prevent the heating rod from "dry burning".

[0040] For further information, see Figure 4 The liquid level detection mechanism 500 may include a button 511, a suspension line 520, and a float 530. The button 511 may be disposed on the bottom surface of the interior of the housing 100. The suspension line 520 may be connected to the top of the housing 100. The float 530 may be connected to the top of the housing 100 through the suspension line 520, the float 530 may be located above the button 511, and the button 511 may be configured to send a signal when in contact with the float 530.

[0041] It is understandable that the height of the float 530 in the second chamber 140 will decrease as the amount of grease decreases until the float 530 contacts the button 511. At this time, the button 511 will send a signal to the center console, colored lights or buzzer, and the user will pay attention to the amount of grease in the second chamber 140 in time according to the prompts of the center console, colored lights or buzzer, thereby avoiding "dry burning" of the heating rod.

[0042] In this implementation, see Figure 4 The liquid level detection mechanism 500 may further include an alarm 512, which may be disposed on the housing 100 and electrically connected to the button 511. When the float 530 contacts the button 511, the button 511 sends a signal, and the alarm 512 receives the signal sent by the button 511. The alarm 512 may emit a buzzer or continuously flash a light to remind the user to pay attention to the amount of grease in the second chamber 140.

[0043] In one embodiment, see Figure 1 and Figure 2 , the distance between the oil inlet 110 and the bottom surface of the housing 100 is greater than the distance between the oil outlet 120 and the bottom surface of the housing 100. By providing the oil inlet 110 at the top surface of the housing 100 close to the housing 100, the grease in the first chamber 130 can be prevented from flowing back out. By providing the oil outlet 120 at the bottom surface of the housing 100 close to the housing 100, after the heating rod is turned off, the grease in the second chamber 140 can be easily drained, and the grease can be prevented from accumulating in the second chamber 140 for a long time.

[0044] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
