Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more specifically, to a valve assembly, a compressor, and an air conditioner. Background Technology

[0002] In related technologies, the valve assembly of a compressor is usually located on the surface of the compressor housing, making it susceptible to damage from impacts. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the first aspect of this application proposes a valve assembly.

[0005] The second aspect of this application proposes a compressor.

[0006] The third aspect of this application proposes an air conditioner.

[0007] In view of the above, a first aspect of this application provides a valve assembly comprising: a valve body, a cover, a mounting portion, and a limiting portion. The valve body is disposed on the mounting portion, the cover is used to cover the valve body, the mounting portion is used to fix the cover to the mounting portion, and the limiting portion is disposed on the cover, abutting against the valve body, and limiting the position of the cover.

[0008] In this technical solution, the compressor includes a valve assembly. The control system can control the switching of the valve assembly to control the bypass channel, thereby changing the compressor's compression volume through bypass. When used in an air conditioner, the valve assembly needs to be connected to the wiring in the air conditioner. The wiring is located on the surface of the compressor housing; therefore, the valve assembly needs to be located on the surface of the compressor housing.

[0009] The valve body is located at the installation section, and the cover is placed over the valve body. The installation section is connected to the installation section, so that the cover is fixed to the installation section through the installation section. This allows the cover to provide a stable structural protection for the valve body and a safe and stable installation environment, preventing the valve body from being damaged by collisions during transportation or use.

[0010] The limiting part is located on the cover and abuts against the valve body. By abutting, the limiting part limits the cover to prevent the cover from rotating relative to the valve body or colliding with the valve body, thereby improving the stability of the cover and ensuring the protective effect of the cover on the valve body.

[0011] In addition, the valve assembly of the above-mentioned technical solution provided in this application may also have the following additional technical features:

[0012] Optionally, in some of the technical solutions provided in this application, the cover is provided with a receiving cavity for accommodating the valve body, and the inner wall shape of the receiving cavity is adapted to the outer contour of the valve body.

[0013] In this technical solution, the cover is provided with a receiving cavity that can accommodate the valve body. The inner wall shape of the receiving cavity is adapted to the outer contour of the valve body. Along the installation direction, the projection of the inner wall contour of the receiving cavity can cover the projection of the outer contour of the valve body, and leave a fitting space so that the receiving cavity of the cover can completely accommodate the valve body. The receiving cavity occupies an appropriate space, which ensures the protective effect of the cover on the valve body while reducing the space occupied by the cover.

[0014] Optionally, in some of the technical solutions provided in this application, the mounting part is also used to fix the valve body to the part to be installed.

[0015] In this technical solution, the valve body is provided with a through hole, through which the mounting part can pass to fix the valve body to the part to be installed. This allows the mounting part to fix both the cover and the valve body to the part to be installed, improving the functionality of the mounting part, saving the parts used for installation of the valve assembly, and simplifying the structure of the valve assembly.

[0016] In some of the technical solutions provided in this application, optionally, a first mounting hole is provided on the valve body. The limiting part includes: a first locking member, a second mounting hole is provided on the cover, the first locking member passes through the first mounting hole and the second mounting hole, and the first locking member is used to fix the valve body to the part to be installed.

[0017] In this technical solution, the valve body has a first mounting hole, and the cover has a second mounting hole. A first locking member passes through the first and second mounting holes, limiting the cover and preventing it from rotating relative to the valve body. Furthermore, the first locking member connects to the part to be installed, enabling it to both limit the cover and fix the valve body to the part to be installed, thus improving the functionality of the first locking member, saving valve assembly components, and simplifying the valve assembly structure.

[0018] In some technical solutions provided in this application, optionally, the mounting part includes a second locking member, and the cover has a third mounting hole. The second locking member passes through the third mounting hole to fix the cover to the part to be mounted. The first locking member is clearance-fitted with the second mounting hole, and / or the second locking member is interference-fitted with the third mounting hole.

[0019] In this technical solution, the second locking member passes through the third mounting hole on the cover, and the cover is connected to the part to be installed through the second locking member, so that the cover is fixed on the part to be installed, thereby improving the stability of the cover.

[0020] The second locking element and the third mounting hole are interference-fitted to improve the stability of the connection between the cover and the part to be installed, prevent the cover from moving relative to the part to be installed, and improve the connection strength and fixing effect between the cover and the part to be installed.

[0021] The first locking element and the second mounting hole are fitted with a clearance, which reduces the installation difficulty between the cover and the valve body and improves the installation convenience of the cover.

[0022] In some of the technical solutions provided in this application, optionally, the length of the interference fit between the second locking member and the third mounting hole along the length direction of the second locking member is L, where L satisfies 5mm≤L≤8mm.

[0023] In this technical solution, along the length direction of the second locking member, the length of the interference fit between the second locking member and the third mounting hole is L, 5mm≤L≤8mm. This range avoids the connection strength being too low due to L being too small, and also avoids the installation operation being too difficult due to L being too large. This ensures that the value of L is within a reasonable and effective range, thereby improving the reliability and operability of the connection between the cover and the mounting part.

[0024] Optionally, in some of the technical solutions provided in this application, the valve body is provided with a protrusion, and the limiting part includes a limiting hole, with the protrusion inserted into the limiting hole.

[0025] In this technical solution, the protrusion on the valve body is inserted into the limiting hole of the limiting part. The shape of the limiting hole matches the shape of the protrusion. The limiting hole and the protrusion cooperate to limit the cover, improve the stability of the cover, prevent the cover from rotating relative to the valve body, and eliminate the need for additional limiting components to limit the cover, saving the parts used for limiting and simplifying the structure of the valve assembly.

[0026] In some of the technical solutions provided in this application, optionally, the valve body includes a first end face, which is circumferentially distributed along the axis of the valve body. The limiting part includes a stop rib, which abuts against the first end face.

[0027] In this technical solution, the first end face of the valve body is circumferentially distributed along the axis of the valve body, and the baffle of the limiting part abuts against the first end face. The baffle and the first end face limit the cover body, prevent the cover body from rotating, improve the stability of the cover body, and save the parts used for limiting, thus simplifying the structure of the valve assembly.

[0028] In some of the technical solutions provided in this application, optionally, the number of retaining ribs is at least two, and the at least two retaining ribs are distributed at intervals in the circumferential direction on the first end face.

[0029] In this technical solution, there are at least two baffles, which are distributed at intervals in the circumferential direction on the first end face to improve the limiting effect of the baffles on the cover, thereby improving the stability of the cover.

[0030] In some of the technical solutions provided in this application, the valve body may optionally include: a valve body and a wiring part, the wiring part being disposed on the valve body, and a cover being disposed on the valve body and the wiring part.

[0031] In this technical solution, the wiring part is located on the valve body, and the cover is placed on the valve body and the wiring part. This allows the cover to provide structural protection for both the valve body and the wiring part, preventing damage from external impacts. It also eliminates the need for an additional wiring protection box to protect the wiring part, saving on the protective components required for the valve assembly and simplifying its structure.

[0032] The second aspect of this application provides a compressor, which includes a part to be installed and a valve assembly provided by any of the first aspects of this application, the valve assembly being connected to the part to be installed.

[0033] It should be noted that the compressor, because it includes the valve assembly provided by any of the above-mentioned technical solutions of this application, has all the beneficial technical effects of the valve assembly, and will not be described in detail here to avoid repetition.

Detailed Implementation

[0053] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0054] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0055] The following reference Figures 1 to 13 This application describes a valve assembly 10, a compressor, and an air conditioner according to some embodiments.

[0056] A first aspect of this application provides a valve assembly 10, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 12 As shown, the valve assembly 10 includes: a valve body 100, a cover 200, a mounting portion 300, and a limiting portion 400. The valve body 100 is disposed on the mounting portion 500, the cover 200 is used to cover the valve body 100, the mounting portion 300 is used to fix the cover 200 to the mounting portion 500, and the limiting portion 400 is disposed on the cover 200, abutting against the valve body 100, and the limiting portion 400 is used to limit the position of the cover 200.

[0057] In this embodiment, the compressor includes a valve assembly 10. The control system can control the switching of the valve assembly 10 to control the bypass channel, thereby changing the compression volume of the compressor through bypass. When the valve assembly 10 is used in an air conditioner, it needs to be connected to the wiring in the air conditioner. The wiring is located on the surface of the compressor housing, therefore the valve assembly 10 needs to be located on the surface of the compressor housing.

[0058] The valve body 100 is located on the installation part 500, and the cover 200 covers the outside of the valve body 100. The mounting part 300 is connected to the installation part 500, so that the cover 200 is fixed to the installation part 500 through the mounting part 300. This allows the cover 200 to provide a stable structural protection for the valve body 100 and provides a safe and stable installation environment for the valve body 100, preventing the valve body 100 from being damaged by collisions during transportation or use.

[0059] The limiting part 400 is provided on the cover 200 and abuts against the valve body 100. By abutting, the limiting part 400 limits the cover 200, preventing the cover 200 from rotating relative to the valve body 100 or from colliding with the valve body 100, thereby improving the stability of the cover 200 and ensuring the protective effect of the cover 200 on the valve body 100.

[0060] For example, the valve body 100 may be a solenoid valve, and the mounting part 500 may be the housing of a compressor.

[0061] In some embodiments provided in this application, such as Figure 1 , Figure 2 , Figure 8 , Figure 10 and Figure 11 As shown, optionally, the cover 200 is provided with a receiving cavity 210 for receiving the valve body 100, and the inner wall shape of the receiving cavity 210 is adapted to the outer contour of the valve body 100.

[0062] In this embodiment, the cover 200 is provided with a receiving cavity 210 capable of accommodating the valve body 100. The inner wall shape of the receiving cavity 210 is adapted to the outer contour of the valve body 100, such as... Figure 10 As shown in the figure, the arrow at point A points in the direction of the installation of the cover 200 and the valve body 100. Along this installation direction, the inner wall contour projection of the receiving cavity 210 can cover the outer contour projection of the valve body 100, and leave a fitting space so that the receiving cavity 210 of the cover 200 can completely accommodate the valve body 100, and the receiving cavity 210 occupies an appropriate space. While ensuring the protective effect of the cover 200 on the valve body 100, it reduces the space occupied by the cover 200.

[0063] In some embodiments provided in this application, such as Figure 4 and Figure 5 As shown, optionally, the mounting part 300 is also used to fix the valve body 100 to the mounting part 500.

[0064] In this embodiment, the valve body 100 is provided with a through hole, through which the mounting part 300 can pass to fix the valve body 100 to the mounting part 500. This allows the mounting part 300 to fix both the cover 200 and the valve body 100 to the mounting part 500, improving the functionality of the mounting part 300, saving the parts used for installation of the valve assembly 10, and simplifying the structure of the valve assembly 10.

[0065] In some embodiments provided in this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, optionally, the valve body 100 is provided with a first mounting hole 110. The limiting part 400 includes: a first locking member 410, and the cover 200 is provided with a second mounting hole 220. The first locking member 410 passes through the first mounting hole 110 and the second mounting hole 220. The first locking member 410 is used to fix the valve body 100 to the part to be installed 500.

[0066] In this embodiment, the valve body 100 is provided with a first mounting hole 110, and the cover 200 is provided with a second mounting hole 220. A first locking member 410 passes through the first mounting hole 110 and the second mounting hole 220, limiting the cover 200 and preventing it from rotating relative to the valve body 100. Furthermore, the first locking member 410 is connected to the part to be installed 500, enabling it to both limit the cover 200 and fix the valve body 100 to the part to be installed 500, thus improving the functionality of the first locking member 410, saving on the components of the valve assembly 10, and simplifying the structure of the valve assembly 10.

[0067] In some embodiments provided in this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, optionally, the mounting part 300 includes a second locking member 310, and the cover 200 is provided with a third mounting hole 230. The second locking member 310 passes through the third mounting hole 230 to fix the cover 200 to the part to be mounted 500. The first locking member 410 is clearance-fitted with the second mounting hole 220, and / or the second locking member 310 is interference-fitted with the third mounting hole 230.

[0068] In this embodiment, the second locking member 310 passes through the third mounting hole 230 on the cover 200, and the cover 200 is connected to the part to be installed 500 through the second locking member 310, so that the cover 200 is fixed on the part to be installed 500, thereby improving the stability of the cover 200.

[0069] The second locking member 310 and the third mounting hole 230 are interference-fitted to improve the stability of the connection between the cover 200 and the part to be installed 500, prevent the cover 200 from moving relative to the part to be installed 500, and improve the connection strength and fixing effect between the cover 200 and the part to be installed 500.

[0070] The first locking element 410 and the second mounting hole 220 are fitted with a clearance, which reduces the installation difficulty between the cover 200 and the valve body 100 and improves the installation convenience of the cover 200.

[0071] In one possible embodiment, the valve body 100 is provided with a through hole, through which the second locking member 310 can pass to lock the valve body 100 onto the installation part 500. This allows the second locking member 310 to both fix the cover 200 and the valve body 100 onto the installation part 500, thereby improving the functionality of the second locking member 310, saving on the parts used for installation of the valve assembly 10, and simplifying the structure of the valve assembly 10.

[0072] It should be noted that when installing the cover 200, first insert part of the second locking member 310 into the third mounting hole 230 to obtain the approximate installation position of the cover 200. Then adjust the relative position of the cover 200 and the valve body 100 so that the first locking member 410 engages with the second mounting hole 220 to prevent the cover 200 from rotating. At the same time, the second locking member 310 is fully inserted into the third mounting hole 230 to completely fix the cover 200.

[0073] In some embodiments provided in this application, such as Figure 13 As shown, optionally, along the length direction of the second locking member 310, the length of the interference fit between the second locking member 310 and the third mounting hole 230 is L, where L satisfies 5mm≤L≤8mm.

[0074] In this embodiment, such as Figure 13 As shown in the figure, the arrow at point H points in the direction of the length of the second locking member 310. Along the length of the second locking member 310, the length of the interference fit between the second locking member 310 and the third mounting hole 230 is L, 5mm≤L≤8mm. This range of values ​​avoids the connection strength being too low due to L being too small, and also avoids the installation operation being too difficult due to L being too large. This ensures that the value of L is within a reasonable and effective range, thereby improving the reliability and operability of the connection between the cover 200 and the mounting part 300.

[0075] For example, L can be 5mm, 6mm or 8mm.

[0076] In some embodiments provided in this application, such as Figure 8 , Figure 9 and Figure 10 As shown, optionally, the valve body 100 is provided with a protrusion 120, and the limiting part 400 includes a limiting hole 420, with the protrusion 120 inserted into the limiting hole 420.

[0077] In this embodiment, the protrusion 120 on the valve body 100 is inserted into the limiting hole 420 of the limiting part 400. The limiting hole 420 is adapted to the shape of the protrusion 120. The cover 200 is limited by the cooperation of the limiting hole 420 and the protrusion 120, which improves the stability of the cover 200 and prevents the cover 200 from rotating relative to the valve body 100. In addition, there is no need to use an additional limiting part 400 to limit the cover 200, saving the parts used for limiting and simplifying the structure of the valve assembly 10.

[0078] It should be noted that the protrusion 120 can be an inherent structure on the valve body 100.

[0079] In some embodiments provided in this application, such as Figure 8 and Figure 9As shown, optionally, the mounting portion 300 includes a third locking member 320, and the cover 200 is provided with a fourth mounting hole 240. The third locking member 320 passes through the fourth mounting hole 240 to fix the cover 200 to the mounting portion 500. The limiting hole 420 and the protrusion 120 are fitted with a clearance fit, and / or the third locking member 320 and the fourth mounting hole 240 are fitted with an interference fit.

[0080] In this embodiment, the third locking member 320 passes through the fourth mounting hole 240 on the cover 200, and the cover 200 is connected to the part to be installed 500 through the third locking member 320, so that the cover 200 is fixed on the part to be installed 500, thereby improving the stability of the cover 200.

[0081] The third locking element 320 and the fourth mounting hole 240 are interference-fitted to improve the stability of the connection between the cover 200 and the part to be installed 500, prevent the cover 200 from moving relative to the part to be installed 500, and improve the connection strength and fixing effect between the cover 200 and the part to be installed 500.

[0082] The limiting hole 420 and the protrusion 120 adopt a clearance fit, which reduces the installation difficulty between the cover 200 and the valve body 100 and improves the installation convenience of the cover 200.

[0083] In one possible embodiment, the valve body 100 is provided with a through hole, through which the third locking member 320 can pass to lock the valve body 100 onto the installation part 500. This allows the third locking member 320 to both fix the cover 200 and the valve body 100 onto the installation part 500, thereby improving the functionality of the third locking member 320, saving on the parts used for installation of the valve assembly 10, and simplifying the structure of the valve assembly 10.

[0084] It should be noted that when installing the cover 200, first insert part of the third locking member 320 into the fourth mounting hole 240 to obtain the approximate installation position of the cover 200. Then adjust the relative position of the cover 200 and the valve body 100 so that the limiting hole 420 and the protrusion 120 cooperate to prevent the cover 200 from rotating. At the same time, the third locking member 320 is fully inserted into the fourth mounting hole 240 to completely fix the cover 200.

[0085] In some embodiments provided in this application, such as Figure 10 and Figure 11 As shown, optionally, the valve body 100 includes a first end face 130, which is circumferentially distributed along the axis of the valve body 100. The limiting portion 400 includes a stop rib 430, which abuts against the first end face 130.

[0086] In this embodiment, such as Figure 10As shown in the figure, line P is the axis of valve body 100, and the arrow at position M points in the circumferential direction of the axis. The first end face 130 of valve body 100 is distributed circumferentially along the axis of valve body 100. The baffle 430 of the limiting part 400 abuts against the first end face 130. The baffle 430 and the first end face 130 limit the cover 200, prevent the cover 200 from rotating, improve the stability of the cover 200, and save the parts used for limiting, thus simplifying the structure of valve assembly 10.

[0087] In some embodiments provided in this application, such as Figure 10 and Figure 11 As shown, optionally, the mounting part 300 includes a fourth locking member 330, and the cover 200 is provided with a fifth mounting hole 250. The fourth locking member 330 passes through the fifth mounting hole 250 to fix the cover 200 to the part 500 to be mounted. The fourth locking member 330 and the fifth mounting hole 250 are interference-fitted.

[0088] In this embodiment, the fourth locking member 330 passes through the fifth mounting hole 250 on the cover 200, and the cover 200 is connected to the part to be installed 500 through the fourth locking member 330, so that the cover 200 is fixed on the part to be installed 500, thereby improving the stability of the cover 200.

[0089] The fourth locking member 330 and the fifth mounting hole 250 are interference fit, which improves the stability of the connection between the cover 200 and the part to be installed 500, prevents the cover 200 from moving relative to the part to be installed 500, and improves the connection strength and fixing effect between the cover 200 and the part to be installed 500.

[0090] In one possible embodiment, the valve body 100 is provided with a through hole, through which the fourth locking member 330 can pass to lock the valve body 100 onto the installation part 500. This allows the fourth locking member 330 to both fix the cover 200 and the valve body 100 onto the installation part 500, thereby improving the functionality of the fourth locking member 330, saving on the parts used for installation of the valve assembly 10, and simplifying the structure of the valve assembly 10.

[0091] It should be noted that when installing the cover 200, first insert part of the fourth locking member 330 into the fifth mounting hole 250 to obtain the approximate installation position of the cover 200. Then adjust the relative position of the cover 200 and the valve body 100. The baffle 430 abuts against the first end face 130 to prevent the cover 200 from rotating. At the same time, the fourth locking member 330 is fully inserted into the fifth mounting hole 250 to completely fix the cover 200.

[0092] In some embodiments provided in this application, such as Figure 11As shown, optionally, the number of retaining ribs 430 is at least two, and the at least two retaining ribs 430 are distributed at intervals in the circumferential direction of the first end face 130.

[0093] In this embodiment, the number of retaining ribs 430 is at least two, such as Figure 10 As shown, the arrow at position M points in the circumferential direction of the axis. At least two baffles 430 are distributed at intervals in the circumferential direction of the first end face 130 to improve the limiting effect of the baffles 430 on the cover 200, thereby improving the stability of the cover 200.

[0094] In some embodiments provided in this application, such as Figure 3 As shown, optionally, the valve body 100 includes: a valve body 140 and a wiring portion 150, the wiring portion 150 being disposed on the valve body 140, and a cover 200 covering the valve body 140 and the wiring portion 150.

[0095] In this embodiment, the wiring portion 150 is disposed on the valve body 140, and the valve body 140 is electrically connected to the wiring portion 150. The wiring portion 150 is used for connection with the wiring in the air conditioner. The cover 200 covers the valve body 140 and the wiring portion 150, so that the cover 200 can provide structural protection for both the valve body 140 and the wiring portion 150, preventing the valve body 140 and the wiring portion 150 from being damaged by external impacts, avoiding the need for an additional wiring protection box for protecting the wiring portion 150, saving the components used for protection in the valve assembly 10, and simplifying the structure of the valve assembly 10.

[0096] In one possible embodiment, the cover 200 includes a first cover portion and a second cover portion, which are connected to each other, and the first cover portion and the second cover portion are integrally formed, which simplifies the installation process of the first cover portion and the second cover portion.

[0097] A second aspect of this application provides a compressor, which includes a part to be installed 500 and a valve assembly 10 provided in any of the first aspects of this application, the valve assembly 10 being connected to the part to be installed 500.

[0098] It should be noted that the compressor includes the valve assembly 10 provided in any of the above embodiments of this application, and therefore has all the beneficial technical effects of the valve assembly 10. To avoid repetition, these effects will not be described in detail here.

[0099] A third aspect of this application provides an air conditioner that includes the compressor provided in the second aspect of this application described above.

[0100] It should be noted that the air conditioner includes the compressor provided in the above embodiments of this application, and therefore has all the beneficial technical effects of the compressor described above. To avoid repetition, it will not be described in detail here.

[0101] In one possible embodiment, the projection of the protective device (i.e., the cover 200) onto the solenoid valve in the installation direction can completely cover the projection of the solenoid valve, with a certain amount of space left. The inner contour of the protective device can completely accommodate the solenoid valve that needs to be protected, thereby achieving the function of preventing damage to the solenoid valve.

[0102] The protective device has a feature hole (i.e., the third mounting hole 230) that is interference-fitted with a screw (i.e., the second locking member 310) used to fix the protective device. The interference fit section is 5mm to 8mm long to fix the protective device and prevent the protective device from moving axially along the screw. The protective device also has a feature rib (i.e., a retaining rib 430) designed to match the raised features of the solenoid valve's metal housing and prevent the protective device from rotating circumferentially along the screw.

[0103] When installing the protective device, the screws that fix the protective device are first partially inserted into the feature holes on the protective device to obtain the relative position of the protective device and the screws. Then, the relative position of the protective device and the screws is adjusted so that the feature ribs on the protective device mate with the upper end face and side end face (the upper end face and side end face, i.e., the first end face 130) of the solenoid valve to prevent the protective device from rotating along the screws. At the same time, the screws are fully inserted into the feature holes of the protective device, so that the protective device is fixed by the housing and the solenoid valve alone, simplifying the parts requirements.

[0104] The limiting hole 420 cooperates with the cylindrical protrusion on the surface of the solenoid valve to prevent the protection device from rotating along the screw, thereby fixing the protection device.

[0105] The protective device also has a second mounting hole 220, which is used to clearance fit the first locking member 410 to prevent the protective device from rotating circumferentially along the screw. During installation, the screw securing the protective device is first partially inserted into the device to determine the relative position between the device and the screw. Then, the position is adjusted so that the second mounting hole 220 on the protective device clearance fits the first locking member 410 on the housing, preventing the protective device from rotating along the screw. Simultaneously, the screw is fully inserted into the characteristic hole of the protective device. Thus, the protective device is secured solely by the first locking member 410 on the housing used to secure the solenoid valve and the screw, simplifying the component requirements.

[0106] In addition, the feature holes and second mounting holes 220 used for interference fit and clearance fit with screws are not limited to round holes, but also include other features that can be interference fit with screws, such as square holes, ribs, etc.

[0107] The solenoid valve protection device provided by this utility model effectively covers the surface of the solenoid valve and its wiring, preventing the possibility of impacts with the external environment and thus achieving the function of preventing damage to the solenoid valve. It is fixed by an interference fit with screws that secure the protection device, and these screws also mate with the raised features of the solenoid valve. This direct fixation of the protection device eliminates the need for a wiring protection box, achieving the goal of optimizing components and saving space.
