DETAILED DESCRIPTION

[0040] In the description of the embodiments of the present application, it should be noted that the terms "extension direction" and "first direction" are based on the attached Figure 5 The orientation or positional relationship shown. These orientation terms are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0041] The present application embodiment provides a wire-passing rubber ring 11, see Figures 4 to 6 , Fig. 9 and Fig.10 The wire-passing rubber ring 11 includes a sealing body 111 and an extrusion structure 112 arranged on the sealing body 111 .

[0042] The sealing body 111 is formed with a sealing groove 1111a that can be expanded. The extrusion structure 112 includes a first extrusion portion 1121 and a second extrusion portion 1122 that are arranged opposite to each other, and a wire-passing opening 112a that communicates with the sealing groove 1111a is formed between the first extrusion portion 1121 and the second extrusion portion 1122, wherein the first extrusion portion 1121 and the second extrusion portion 1122 are moved closer to each other under the action of the extrusion force to close the wire-passing opening 112a.

[0043] See also Fig. 9 The sealing groove 1111a is used for the wire body 60 to pass through, and the wire body 60 is a connecting wire for electrical components to achieve electrical connection. "Can be expanded" means that when the wire body 60 is inserted into the sealing groove 1111a, the shape and size of the sealing groove 1111a can be expanded by the wire body 60, and when the wire body 60 is taken out of the sealing groove 1111a, the sealing groove 1111a can return to its original state. In other words, the sealing body 111 can produce a certain elastic deformation under the force of the wire body 60, so that after the wire body 60 is inserted into the sealing groove 1111a, the wire body 60 can contact the groove wall of the sealing groove 1111a to achieve a better sealing effect.

[0044] The wire passing opening 112a is an entrance for the wire body 60 to be inserted into the sealing groove 1111a. The wire body 60 can be directly inserted into the sealing groove 1111a through the wire passing opening 112a.

[0045] The extrusion force is an external force acting on the first extrusion portion 1121 and the second extrusion portion 1122. Under the extrusion force, the first extrusion portion 1121 and the second extrusion portion 1122 produce a certain elastic deformation to approach each other, thereby closing the wire passing opening 112a.

[0046] The first extrusion portion 1121 and / or the second extrusion portion 1122 that are close to each other may abut against the wire body 60 in the sealing groove 1111 a to fix the wire body 60 , prevent the wire body 60 from loosening, and seal the wire body 60 .

[0047] In some embodiments, the first extrusion portion 1121 and the second extrusion portion 1122 , which are close to each other, may also form a certain gap with the wire body 60 .

[0048] The wire-passing rubber ring 11 can be made of rubber material. Rubber has good elastic deformation ability, can produce greater deformation under a smaller force, and can restore its shape more quickly after the external force is removed. Therefore, the wire-passing rubber ring 11 can have good sealing and deformation ability.

[0049] The sealing body 111 and the extrusion structure 112 can be integrally formed to reduce the number of parts of the wire-passing rubber ring 11 , improve production efficiency, and reduce production costs.

[0050] The present application embodiment also provides a wire-passing structure 10, see Figure 3 , Figures 7 and 8 The wire passing structure 10 includes a mounting panel 12, an extrusion member 13, and a wire passing rubber ring 11 provided in any embodiment of the present application. The mounting panel 12 has a mounting notch 12a, the wire passing rubber ring 11 is arranged at the mounting notch 12a, and the extrusion member 13 applies an extrusion force to the first extrusion portion 1121 and the second extrusion portion 1122. That is, the extrusion member 13 extrudes the first extrusion portion 1121 and the second extrusion portion 1122 so that the first extrusion portion 1121 and the second extrusion portion 1122 are close to each other to close the wire passing opening 112a.

[0051] The present application also provides a new air blower. Figures 1 to 3 The new air fan includes the wire passing structure 10 provided in any embodiment of the present application.

[0052] Please continue reading Figures 1 to 3 The new air fan includes a shell 20, a cover plate, a partition and two fans 50. One side of the shell 20 has an opening. The partition plate and the two fans 50 are both arranged in the shell 20, and the two fans 50 are respectively located on opposite sides of the partition plate. The cover plate is arranged at the opening, wherein the partition plate is a mounting panel 12, and the cover plate is an extruded part 13.

[0053] Specifically, see Figure 1 and Figure 2 The housing 20 has a first air inlet 20a, a first air outlet 20b, a second air inlet 20c, and a second air outlet 20d, and a heat exchange core 40 is disposed in the housing 20. A first air flow path passing through the heat exchange core 40 and a fan cavity is formed between the first air inlet 20a and the first air outlet 20b, and a second air flow path passing through the heat exchange core 40 and another fan cavity is formed between the second air inlet 20c and the second air outlet 20d.

[0054] Figure 1 and Figure 2 The first air inlet 20a and the second air outlet 20d shown are connected to the outdoor environment respectively, and the second air inlet 20c and the first air outlet 20b are connected to the indoor environment respectively. That is to say, the first air flow path is a fresh air path, and the outdoor air flows into the indoor through the first air inlet 20a and the first air outlet 20b. The second air flow path is a return air path, and the indoor air flows to the outdoors through the second air inlet 20c and the second air outlet 20d.

[0055] In other embodiments, the first air flow path may be a return air path, and the second air flow path may be a fresh air path.

[0056] See also Figure 1The partition is used to separate two fan chambers in the housing 20, and a fan 50 is respectively arranged in the two fan chambers. The two fans 50 are used to drive the airflow to flow along the first airflow path and the second airflow path respectively, so as to realize the indoor and outdoor gas exchange.

[0057] See also Figure 1 and Figure 2 The installation notch 12a is located on the side of the partition close to the cover plate, and the wire body 60 of the electric components such as the fan 50 and the sensor 30 (such as a temperature sensor) of the fresh air fan can be inserted into the sealing groove 1111a of the wire-passing rubber ring 11. When the cover plate is set at the opening, the cover plate can squeeze the first extrusion part 1121 and the second extrusion part 1122 so that the first extrusion part 1121 and the second extrusion part 1122 are close to each other, thereby closing the wire-passing opening 112a.

[0058] Since there are two air flow paths in different directions on both sides of the partition, in order to prevent the air flow in the first air flow path and the air flow in the second air flow path from interfering with and mixing with each other, the partition needs to have a certain degree of sealing, and the partition needs to pass the line. Therefore, the passing line position on the partition should preferably meet the requirements of both easy passing of the line and good sealing.

[0059] The wire-passing rubber ring 11 of the embodiment of the present application is provided with a sealing body 111 and an extrusion structure 112 having a first extrusion part 1121 and a second extrusion part 1122. The sealing body 111 is formed with a sealing groove 1111a that can be expanded. The wire body 60 is inserted into the sealing groove 1111a through the wire-passing opening 112a between the first extrusion part 1121 and the second extrusion part 1122, which can reduce the difficulty of wire-passing operation and improve the convenience of operation. At the same time, since the sealing groove 1111a adopts an expandable structure, the wire body 60 inserted into the sealing groove 1111a can contact the groove wall of the sealing groove 1111a to play a sealing role, and the first extrusion part 1121 and the second extrusion part 1122 are close to each other under the action of the extrusion force to close the wire-passing opening 112a, which can further ensure the sealing effect of the wire-passing rubber ring 11. Therefore, the wire-passing rubber ring 11 of the embodiment of the present application is convenient for wire passing and has good sealing performance.

[0060] It should be noted that the wire-passing rubber ring 11 of the embodiment of the present application is not limited to being used on fresh air fans, and any other equipment that requires sealing can adopt the wire-passing rubber ring 11 of the embodiment of the present application.

[0061] In one embodiment, please refer to Figure 4 and Figure 5 , Fig. 9 and Fig.10The first extrusion portion 1121 may include a first sealing block 11211 and a first sealing sheet 11212 arranged on the first sealing block 11211, and the second extrusion portion 1122 may include a second sealing block 11221 and a second sealing sheet 11222 arranged on the second sealing block 11221. Under the action of the extrusion force, the first sealing block 11211 and the second sealing block 11221 approach each other, so that the first sealing sheet 11212 and the second sealing sheet 11222 contact to close the wire opening 112a.

[0062] The first sealing block 11211 and the second sealing block 11221 are used to withstand the extrusion force and can approach each other under the extrusion force to drive the first sealing sheet 11212 and the second sealing sheet 11222 to contact each other. The first sealing sheet 11212 and the second sealing sheet 11222 can close the wire opening 112a by contacting each other.

[0063] For example, please refer to Figure 4 and Figure 5 , Fig. 9 and Fig.10 The first sealing sheet 11212 and the second sealing sheet 11222 may be respectively located at one side where the first sealing block 11211 and the second sealing block 11221 are close to each other, and a wire passing opening 112a is formed between the first sealing sheet 11212 and the second sealing sheet 11222.

[0064] The purpose of the first sealing sheet 11212 and the second sealing sheet 11222 being respectively located on the side where the first sealing block 11211 and the second sealing block 11221 are close to each other is that when the first sealing block 11211 and the second sealing block 11221 are close to each other, the first sealing sheet 11212 and the second sealing sheet 11222 can contact each other. At the same time, since the wire-passing opening 112a is formed by spacing the first sealing sheet 11212 and the second sealing sheet 11222, when the first sealing sheet 11212 and the second sealing sheet 11222 contact each other, the wire-passing opening 112a can be closed.

[0065] In one embodiment, please refer to Figure 4 The thickness of the first sealing sheet 11212 may be smaller than the thickness of the first sealing block 11211 , and the thickness of the second sealing sheet 11222 may be smaller than the thickness of the second sealing block 11221 .

[0066] That is to say, the first sealing block 11211 and the second sealing block 11221 are thicker and have better compressive strength and rigidity, ensuring that the first sealing block 11211 and the second sealing block 11221 will not be excessively deformed under the action of the extrusion force. The first sealing sheet 11212 and the second sealing sheet 11222 are thinner. When the first sealing block 11212 and the second sealing sheet 11222 are in contact with each other under the action of the extrusion force, the first sealing sheet 11212 and the second sealing sheet 11222 can be deformed to a certain extent, thereby further improving the sealing effect.

[0067] In one embodiment, please refer to Figure 4 and Figure 5 The first sealing block 11211 and the second sealing block 11221 can protrude from the same side of the sealing body 111 along the extension direction of the sealing groove 1111a. The first sealing block 11211 has a first extrusion surface 11211a on the side away from the sealing body 111, and the second sealing block 11221 has a second extrusion surface 11221a on the side away from the sealing body 111.

[0068] The first sealing block 11211 and the second sealing block 11221 protrude from the same side of the sealing body 111 along the extending direction of the sealing groove 1111a, so as to facilitate the application of extrusion force to the first sealing block 11211 and the second sealing block 11221. The extrusion force is applied to the first extrusion surface 11211a and the second extrusion surface 11221a, so that the first sealing block 11211 and the second sealing block 11221 can move in the direction close to the sealing body 111, and at the same time, the first sealing block 11211 and the second sealing block 11221 are close to each other.

[0069] For example, see Figure 4 and Figure 5 The first extrusion surface 11211a and the second extrusion surface 11221a are both arc surfaces that protrude away from the sealing body 111. It can be understood that the arc surface can make the force on the first extrusion surface 11211a and the second extrusion surface 11221a more uniform, and the arc surface has better structural stability.

[0070] See also Figure 4 and Figure 5 The first sealing block 11211 may have a first inclined surface 11211b and a second inclined surface 11211c, wherein the first inclined surface 11211b is located on the side of the first extrusion surface 11211a close to the second extrusion portion 1122, and the second inclined surface 11211c is located on the side of the first extrusion surface 11211a away from the first inclined surface 11211b, and both the first inclined surface 11211b and the second inclined surface 11211c are inclined toward the direction close to the sealing body 111.

[0071] That is to say, the first inclined surface 11211b and the second inclined surface 11211c are respectively located on both sides of the first extrusion surface 11211a, and the first inclined surface 11211b and the second inclined surface 11211c are both inclined in the direction close to the sealing body 111, thereby making the first extrusion surface 11211a protrude from the same side of the sealing body 111 along the extension direction of the sealing groove 1111a, so that the first extrusion surface 11211a can be better stressed.

[0072] Please continue reading Figure 4 and Figure 5 The second sealing block 11221 can have a third inclined surface 11221b and a fourth inclined surface 11221c, the third inclined surface 11221b is located on the side of the first extrusion surface 11211a close to the first extrusion portion 1121, and the fourth inclined surface 11221c is located on the side of the second extrusion surface 11221a away from the third inclined surface 11221b, and the third inclined surface 11221b and the fourth inclined surface 11221c are both inclined in a direction close to the sealing body 111.

[0073] That is to say, the third inclined surface 11221b and the fourth inclined surface 11221c are respectively located on both sides of the first extrusion surface 11211a, and the third inclined surface 11221b and the fourth inclined surface 11221c are both inclined in the direction close to the sealing body 111, thereby making the second extrusion surface 11221a protrude from the same side of the sealing body 111 along the extension direction of the sealing groove 1111a, so that the second extrusion surface 11221a can be better subjected to force.

[0074] For further information, see Figure 4 and Figure 5 The first sealing block 11211 has a first inclined surface 11211b and a second inclined surface 11211c, the second sealing block 11221 has a third inclined surface 11221b and a fourth inclined surface 11221c, the first sealing sheet 11212 is arranged on the first inclined surface 11211b, the second sealing sheet 11222 is arranged on the third inclined surface 11221b, and a wire opening 112a is formed between the first sealing sheet 11212 and the second sealing sheet 11222.

[0075] The first inclined surface 11211b is located on the side of the first extrusion surface 11211a close to the second extrusion portion 1122, and the third inclined surface 11221b is located on the side of the first extrusion surface 11211a close to the first extrusion portion 1121. That is to say, the first inclined surface 11211b and the third inclined surface 11221b are respectively located on the side where the first sealing block 11211 and the second sealing block 11221 are close to each other, and the first sealing sheet 11212 and the second sealing sheet 11222 are respectively arranged on the first inclined surface 11211b and the third inclined surface 11221b. When the extrusion force makes the first inclined surface 11211b and the third inclined surface 11221b close to each other, the first sealing sheet 11212 and the second sealing sheet 11222 can contact each other.

[0076] In one embodiment, please refer to Figure 4 and Figure 5 The sealing body 111 may include a sealing portion 1111 and a main body 1112 located around the sealing portion 1111 , the sealing portion 1111 is formed with a sealing groove 1111 a , and the extrusion structure 112 is disposed on the main body 1112 .

[0077] The sealing portion 1111 is used to seal the wire body 60 inserted into the sealing groove 1111 a , and the main body 1112 is used to play a supporting role.

[0078] For example, see Figure 4 and Figure 5 The sealing portion 1111 may be provided with a plurality of strip holes 1111b communicating with the sealing groove 1111a, and each strip hole 1111b extends along a first direction intersecting with an extending direction of the sealing groove 1111a.

[0079] When the wire body 60 is inserted into the sealing groove 1111 a , the deformation stress of the sealing portion 1111 can be released through the strip hole 1111 b , thereby extending the service life of the wire-passing rubber ring 11 .

[0080] Exemplarily, the thickness of the sealing portion 1111 may be less than the thickness of the main body 1112. That is, the thickness of the sealing portion 1111 is small, so that it can be elastically deformed under the force of the wire 60, while the thickness of the main body 1112 is thicker, the rigidity is better, and it is not easy to be elastically deformed with the sealing portion 1111, so as to provide good support force.

[0081] For further information, see Figure 4 and Figure 5, for the wire-passing rubber ring 11 having a first sealing pressure block 11211 and a first sealing sheet 11212 in the first extrusion portion 1121, and a second sealing pressure block 11221 and a second sealing sheet 11222 in the second extrusion portion 1122, the first sealing pressure block 11211 and the second sealing pressure block 11221 can be respectively connected to the sealing portion 1111, and the first sealing pressure block 11211 and the second sealing pressure block 11221 approach each other under the action of the extrusion force, so that the sealing portion 1111 produces elastic deformation, and the first sealing sheet 11212 and the second sealing sheet 11222 contact to close the wire-passing opening 112a.

[0082] That is to say, when the first sealing pressing block 11211 and the second sealing pressing block 11221 are close to each other, the sealing portion 1111 can be driven to produce elastic deformation, and after the sealing portion 1111 is elastically deformed, the surrounding of the wire body 60 can be better sealed.

[0083] In one embodiment, please refer to Figure 4 , Figure 5 and Fig.10 The main body 1112 includes two first sections 11121 and two second sections 11122, the two first sections 11121 and the two second sections 11122 are respectively located on the opposite sides of the sealing portion 1111, and each second section 11122 is respectively located on the side of the first section 11121 on the same side away from the extrusion structure 112, the distance between the two first sections 11121 is greater than the distance between the two second sections 11122, and the two first sections 11121 are respectively connected to the first extrusion portion 1121 and the second extrusion portion 1122.

[0084] The first extrusion portion 1121 and the second extrusion portion 1122 are respectively located on the two first sections 11121. Since the distance between the two first sections 11121 is greater than the distance between the two second sections 11122, when the first extrusion portion 1121 and the second extrusion portion 1122 are forced to approach each other, the first extrusion portion 1121 and the second extrusion portion 1122 can extend between the two first sections 11121 to improve the effect of closing the wire opening 112a.

[0085] See also Figure 4 , Figure 5 and Fig.10 The first extrusion portion 1121 and the second extrusion portion 1122 can be respectively located on one side where the two first sections 11121 are close to each other. Under the action of the extrusion force, the first extrusion portion 1121 and the second extrusion portion 1122 can rotate in the direction of approaching the two second sections 11122 respectively, so as to extend into between the two first sections 11121. At the same time, the first extrusion portion 1121 and the second extrusion portion 1122 are close to each other, thereby closing the wire opening 112a.

[0086] In one embodiment, please refer to Figures 6 to 8 The outer peripheral side of the wire-passing rubber ring 11 has a mounting groove 11a, and at least a portion of the mounting panel 12 located on the peripheral side of the mounting notch 12a extends into the mounting groove 11a.

[0087] By extending the area around the installation notch 12a into the installation groove 11a, the wire-passing rubber ring 11 can be stably and firmly installed at the installation notch 12a.

[0088] For further information, see Figure 8 The profile of the mounting groove 11a can match the profile of the mounting notch 12a so that as much area as possible around the mounting notch 12a extends into the mounting groove 11a, thereby increasing the contact area between the wire-passing rubber ring 11 and the mounting panel 12, ensuring the installation stability of the wire-passing rubber ring 11, and preventing the wire-passing rubber ring 11 from falling off the mounting panel 12.

[0089] See also Figures 6 to 8 The opposite sides of the installation notch 12a respectively have installation buckles 121 protruding from the side walls of the installation notch 12a. The installation groove 11a of the wire-passing rubber ring 11 has a slot 11a1 that is recessed toward the inside of the wire-passing rubber ring 11 and corresponds to the installation buckles 121 one by one. Each installation buckle 121 is inserted into the corresponding slot 11a1.

[0090] Through the cooperation between the mounting buckle 121 and the slot 11a1, not only can the wire-passing rubber ring 11 be stably mounted on the mounting panel 12, but also the wire-passing rubber ring 11 can be easily assembled and disassembled.

[0091] To further ensure the connection stability between the wire-passing rubber ring 11 and the mounting panel 12 , the mounting buckle 121 and the slot 11 a 1 may be interference-fitted.
