[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0033] Embodiment 1

[0034] like Figure 1-Figure 6 As shown, a hand warmer proposed in the first embodiment of the present application includes:

[0035] The housing 1 is shaped as Figure 1 As shown, it is gourd-shaped, and an interlayer 101 is constructed on the wall thickness. A heating component 2 is arranged in the interlayer 101. The heating component 2 is an existing graphene heating chip, which is connected to a power source, so that the graphene emits infrared light waves to convert the light waves into heat to warm the user. A base is arranged at the bottom of the shell 1, and a charging port 102 is constructed on the base of the shell 1. When in use, the charging cable is inserted into the charging port 102 to power the heating component 2, so that it generates heat to warm the user.

[0036] The shielding member 3 is mounted on the housing 1 and is used to shield or unblock the charging port 102. When the hand warmer is idle, the charging port 102 is shielded by the shielding member 3, thereby reducing the possibility of external impurities entering the charging port 102;

[0037] The limiting member 4 is installed on the shielding member 3. The limiting member 4 has a cleaning end and a limiting end. The limiting end is used to be inserted into the charging port 102 so that the movement of the shielding member 3 on the housing 1 is limited. When the limiting end releases the restriction on the shielding member 3, the cleaning end is used to scrape the inner wall of the charging port 102. When in use, the limiting member 4 can limit the movement of the shielding member 3 through the limiting end, which increases the stability of the shielding member 3 when in use. When the hand warmer needs to be used, the restriction on the shielding member 3 by the limiting member 4 is released, and the charging port 102 is scraped and cleaned through the cleaning end, so that the impurities that accidentally entered the charging port 102 when the hand warmer was used last time are scraped and taken out to the outside of the charging port 102, further reducing the possibility of the charging port 102 being blocked;

[0038] The release member 5 is installed on the shielding member 3. The release member 5 has a release end, which is connected to the restriction end. The release end is used to make the restriction end release the restriction on the shielding member 3. When in use, the restriction end of the restriction member 4 releases the restriction on the shielding member 3 through the cooperation of the release member 5, so that the shielding member 3 can release the blocking of the charging port 102, so that the hand warmer can be used normally;

[0039] Compared with the prior art, a heating component 2 is provided on the housing 1 for heating. When the device is not in use, the charging port 102 is blocked by the shielding member 3, thereby reducing the possibility of impurities entering the charging port 102. When in use, the movement of the shielding member 3 is restricted by the limiting member 4, thereby increasing the stability of the shielding member 3 when in use. When the restriction of the limiting member 4 on the shielding member 3 is released by the releasing member 5, the inner wall of the charging port 102 is scraped by the cooperation of the cleaning end thereof, and the impurities remaining in the charging port 102 during the last use are slid out, thereby reducing the possibility of the charging port 102 being blocked and increasing the practicality of the device.

[0040] Embodiment 2

[0041] like Figure 1-Figure 6 As shown, the second embodiment discloses the shielding member 3, the limiting member 4 and the releasing member 5 on the basis of the first embodiment. In the second embodiment, the shielding member 3 includes:

[0042] A hinge rod 301 is hinged to the bottom of the housing 1, and the hinge rod 301 is hinged to the base of the housing 1;

[0043] The shielding plate 302 is installed on the hinged rod 301. The shielding plate 302 is used to shield the charging port 102. The limiting member 4 and the releasing member 5 are installed on the shielding plate 302. An L-shaped structure is formed between the shielding plate 302 and the hinged rod 301. When in use, when the hinged rod 301 is rotated to be coplanar with the bottom of the base of the shell 1, the shielding plate 302 blocks the charging port 102. When it is rotated to be perpendicular to the bottom of the base of the shell 1, the shielding plate 302 releases the blocking of the charging port 102. When in use, the movement of the shielding plate 302 is restricted by the limiting member 4, thereby completing the restriction of the entire shielding member 3, thereby increasing the stability of the shielding member 3 when in use.

[0044] In the second embodiment, the limiting member 4 includes:

[0045] The plug rod 401 is slidably mounted on the shielding plate 302, and the free end of the plug rod 401 is used to be inserted into the charging port 102. A scraper wheel rod 402 is rotatably mounted on the plug rod 401. The release member 5 is connected to the plug rod 401. The plug rod 401 is the limiting end, and the scraper wheel rod 402 is the cleaning end. When in use, the plug rod 401 is slidably inserted into the charging port 102, so that the scraper wheel rod 402 contacts the inner wall of the charging port 102. At this time, if the shielding plate 302 is rotated, the plug rod 401 will conflict with the inner wall of the charging port 102, thereby limiting the rotation of the shielding plate 302;

[0046] A connecting spring 403 is installed between the plug rod 401 and the baffle plate 302. The connecting spring 403 forces the plug rod 401 to be inserted into the charging port 102. When in use, the connecting spring 403 forces the plug rod 401 to be inserted into the charging port 102. During the process, the scraping wheel rod 402 rotates to scrape away impurities attached to the charging port 102, so that the impurities are released from the inner wall of the charging port 102. When the restriction of the baffle plate 302 by the plug rod 401 is released through the cooperation of the release member 5, the scraping wheel rod 402 rubs against the inner wall of the charging port 102 to rotate and bring out the impurities, thereby reducing the possibility of impurities staying in the charging port 102 and clogging it, thereby increasing the practicability of the device.

[0047] In the second embodiment, the release member 6 comprises:

[0048] The ear plate 501 is installed on the plug rod 401. The ear plate 501 is installed with a sliding rod 502 that penetrates the shielding plate 302. The end of the sliding rod 502 located outside is installed with a connecting plate 503. When it is necessary to release the restriction of the plug rod 401 on the shielding plate 302, the sliding rod 502 is pulled outward so that the plug rod 401 squeezes the connecting spring 403, so that the length of the plug rod 401 located in the charging port 102 is reduced, and then when the shielding plate 302 rotates, the plug rod 401 can be smoothly separated from the charging port 102 by compensating for the deformation of the connecting spring 403, so that the shielding plate 302 can release the shielding of the charging port 102, so that the hand warmer can be used normally, and the sliding rod 502 and the ear plate 501 constitute a release end;

[0049] The sliding plate 504 is slidably mounted on the shielding plate 302, and a force-bearing inclined surface is provided on the connecting plate 503. A force-applying inclined surface is provided on the sliding plate 504. When the force-applying inclined surface contacts the force-bearing inclined surface, the connecting plate 503 slides in a direction away from the shielding plate 302. When in use, the force-applying inclined surface is provided in a direction toward the base of the housing 1, and the force-bearing inclined surface is parallel thereto. When in use, the sliding plate 504 is slid downward so that the force-applying inclined surface contacts the force-bearing inclined surface, so that the connecting plate 503 moves in a direction away from the shielding plate 302, and then the connecting plate 503 pulls the sliding rod 502 to move outward, so that the insertion rod 401 releases the restriction on the shielding plate 302;

[0050] The shape of the sliding plate 504 is as follows: Figure 4 As shown, when in use, the user pushes the sliding plate 504 downward in the arc direction, so that the sliding plate 504 moves downward and also has a tendency to move in the arc direction, so that the sliding plate 504 allows the plug 401 to release the restriction on the shielding plate 302, and at the same time, the shielding plate 302 is driven to rotate by the sliding plate 504, and the shielding plate 302 is released from the charging port 102 through fewer actions, thereby increasing the practicality of the device;

[0051] When the shielding plate 302 needs to cover the charging port 102, the sliding plate 504 is slid to first move the insertion rod 401 close to the shielding plate 302, and then the shielding plate 302 is rotated to a position to cover the charging port 102, and then the sliding plate 504 is released to allow the insertion rod 401 to be inserted into the charging port 102 more horizontally, thereby reducing the possibility of damage to the charging port 102 during installation and increasing the practicality of the device.

[0052] Embodiment 3

[0053] like Figure 1-Figure 5As shown, the third embodiment further discloses the present application on the basis of the second embodiment. In the third embodiment, a receiving hole 6 is opened on the side of the baffle plate 302 facing the charging port 102, and the connecting spring 403 is installed in the receiving hole 6. The plug 401 slides with the receiving hole 6. Firstly, when in use, the inner wall of the receiving hole 6 contacts the outer wall of the plug 401, which limits the sliding direction of the plug 401 and increases its stability when sliding. Secondly, an installation position is provided for the connecting spring 403, so that the overall length of the connecting spring 403 and the plug 401 in the charging port 102 is not too long, which facilitates the separation of the plug 401 from the charging port 102.

[0054] In the third embodiment, a T-slot 7 is provided on the shielding plate 302, and a T-block 8 is installed on the sliding plate 504 to slide with the T-slot 7. When in use, the inner wall of the T-slot 7 restricts the side wall of the T-block 8, so that the sliding plate 504 can only slide along a straight line on the shielding plate 302. Moreover, the restriction of the T-slot 7 on the enlarged end of the T-block 8 reduces the possibility of the sliding plate 504 separating from the shielding plate 302, thereby increasing the practicality of the device.

[0055] And when the sliding plate 504 slides so that the connecting spring 403 is compressed to the maximum position, at this time, the insertion rod 401 can already be separated from the charging port 102, but the force-applying inclined surface is still in contact with the force-bearing inclined surface, so that it is blocked by the force-bearing inclined surface, so that the sliding plate 504 will not be separated from the shielding plate 302 along the opening direction of the T-slot 7, further reducing the possibility of it being separated from the shielding plate 302.

[0056] In embodiment three, a plurality of grooves 9 are provided on the surface of the scraping wheel rod 402, and the grooves 9 form a plurality of edges on the surface of the scraping wheel rod 402. When the scraping wheel rod 402 rotates, the edges are used to scrape away impurities attached to the inner wall of the charging port 102. Since the contact area between the edges and the impurities is small, a structure like a scraper is formed, which facilitates scraping of the impurities, and the scraped impurities are accommodated by the grooves 9, thereby reducing the possibility of pushing the impurities into the charging port 102 when the scraping wheel rod 402 enters the charging port 102, thereby increasing the practicability of the device.

[0057] In the third embodiment, the shielding plate 302 is a rubber plate, which is in flexible contact with the charging port 102, thereby reducing the possibility of wear and tear when shielding the charging port 102 and increasing the practicality of the device.

[0058] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
