Description

Technical Field

[0001] This application belongs to the field of medical device technology, specifically relating to a top cover assembly for a respiratory humidification therapy device. Background Technology

[0002] Respiratory humidification therapy devices are mainly used to humidify gases, improve respiratory symptoms, promote drug inhalation, and prevent respiratory dryness. A respiratory humidification therapy device consists of a main body and a cover. The cover and main body work together to form an installation cavity for supporting the main unit, humidification chamber, etc. The cover is equipped with a control panel for setting and adjusting the operating parameters of the humidification therapy device, such as humidification time, humidification intensity, outlet pressure, and oxygen concentration.

[0003] Traditional humidifiers often have a horizontally oriented cover to ensure a tight seal in the mounting cavity, with the control panel located on top of the cover, also horizontally oriented. This presents several problems: when adjusting parameters, the user must view the control panel from top to bottom. To ensure stability and prevent the device from falling off tables or workbenches, it's typically placed away from the edge of the control surface, such as in the center. This makes it difficult for the user to navigate over the obstruction to view the control panel from above, especially with devices placed higher up, requiring adjustment of the device's position and causing inconvenience. In addition, the respiratory humidification therapy device needs to provide humidified gas through the humidification tank located above it when it is working. During the process of adding water or changing water in the humidification tank, there is a possibility that water may splash or drip onto the main unit of the humidification therapy device, and there is a risk that water may seep into the body from the gap between the control panel and the cover, which will have an adverse effect on the working stability of the humidification therapy device. Utility Model Content

[0004] This application provides a top cover assembly for a respiratory humidification therapy device to solve the technical problems of inconvenience for users to operate the control panel in traditional respiratory humidification therapy devices and the susceptibility of the therapy device to water seepage.

[0005] The technical solution adopted in this application is as follows:

[0006] A top cover assembly is installed on the body of a respiratory humidification therapy device. The top cover assembly includes a cover body, which has a mounting part and a control part. The mounting part is installed on the body, and the control part is arranged at an angle to the mounting part and has a control screen that extends obliquely. The top cover assembly also includes a rear cover located between the mounting part and the control part. The rear cover, the cover body, and the body cooperate to form a mounting cavity for installing a drive module.

[0007] The cover assembly described in this application also includes the following additional technical features:

[0013] The cover assembly further includes a lifting member rotatably connected to the cover body. The cover body has an installation area rotatably connected to the lifting member. The second water inlet is located above the installation area. There is a water passage gap between the lifting member and the cover body. The installation area communicates with the outside through the water passage gap.

[0014] The water inlets are distributed on both sides of the first part, and the water-guiding protrusions extend from the high position of the water-guiding slope to the water inlets.

[0015] The first part has a first mounting hole, and the cover has a second mounting hole that aligns with the first mounting hole. The first part is connected to the cover by sequentially inserting mounting parts into the first mounting hole and the second mounting hole.

[0016] The first part has a mounting boss, the mounting boss is hollow inside to form the first mounting hole, the cover has a positioning protrusion, the positioning protrusion is hollow inside to form the second mounting hole, the positioning protrusion and the mounting boss abut against each other to make the first mounting hole and the second mounting hole aligned and connected.

[0017] The first part is provided with a first positioning step, and the cover is provided with a second positioning step that is adapted to the first positioning step. When the first positioning step and the second positioning step are engaged, the first mounting hole and the second mounting hole are aligned.

[0018] The second part is provided with a first limiting hole, and the upper cover assembly also includes a fixing frame connected to the cover body. The fixing frame is provided with a first limiting protrusion, and the first limiting protrusion abuts against the inner wall of the first limiting hole.

[0019] The first limiting protrusion includes a first column located inside the first limiting hole and a second column located below the first column. The cross-sectional area of ​​the second column is larger than that of the first column. The second part is provided with an annular sleeve below the limiting hole, and the second column abuts against the inner wall of the annular sleeve.

[0022] The bottom of the mounting frame has multiple component mounting positions, which are used to install the drive module.

[0023] The bottom of the cover has an opening for the fixing bracket to be inserted into the bottom of the cover. The fixing bracket has a guide groove, and the cover has a guide slide extending in a vertical direction. The guide slide abuts against the inner wall of the guide groove.

[0024] The top of the mounting section is provided with a water-blocking rib that is arranged circumferentially, and the water-blocking rib extends vertically and abuts against the inner wall of the rear cover.

[0025] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0026] 1. The top cover assembly of this application includes a cover having a mounting section and a control section. The mounting section is connected to the body of the therapeutic device, and the control section is arranged at an angle to the mounting section, such that the control screen mounted on the control section extends obliquely, i.e., the control screen forms a certain angle with the horizontal plane. Users only need to stand in front of the therapeutic device to intuitively obtain information on the control screen and operate it from the front of the device. Thus, even when the therapeutic device is placed at a certain distance from the operator, such as in the center of a table, the user does not need to move the therapeutic device and can observe and operate the control screen from the edge of the table, optimizing the user experience. Furthermore, the top cover assembly also includes a rear cover located between the mounting section and the control section. The rear cover, the cover body, and the body together form a mounting cavity, providing a relatively enclosed working environment for the drive module inside the device. This reduces adverse interference from the external environment on the drive module, helping to improve the working stability of the therapeutic device. On the other hand, the rear cover and the cover body shield the internal components of the device, preventing the drive module from being exposed to the user's view, thus optimizing the user's sensory experience.

[0027] 2. In a preferred embodiment of this application, the back cover is configured to include a first part and a second part, so that the back cover can provide a certain support for the control part, reducing the probability of the control part deforming downward under its own weight or during long-term operation, and providing a more stable working environment for the control screen; on this basis, the first part and the second part are set at an angle, and a gripping gap is formed between them. When the user needs to move the therapeutic device, he / she can put his / her hand into the gripping gap to lift the therapeutic device, thereby reducing the user's pressure on the therapeutic device during transportation.

[0028] 3. In a preferred embodiment of this application, the receiving hole on the control unit provides a mounting position for the control screen, allowing the control screen to be stably mounted on the control unit through the receiving hole. The humidification tank, as an important component of the humidification therapy device, heats the water inside the tank using a heating element, causing the water to evaporate and be delivered to the patient's respiratory tract through the breathing tubing to achieve the purpose of humidification therapy. The humidification tank needs to be frequently refilled or its water changed during operation, and it is usually refilled via a suspended water bag. Therefore, during the process of refilling or changing the water, operational issues may arise due to the operator's... In the event of a problem causing water to splash or drip onto the top cover assembly, or if the humidification therapy device encounters rain during transport, water droplets may drip downwards and enter the mounting cavity through the assembly gap between the rear cover 2 and the mounting part 11, or between the rear cover 2 and the control part 12. Water droplets seeping into the assembly gaps will fall onto the water-guiding slope under gravity. Because the water-guiding slope extends obliquely and the water outlet is located at the lower position of the slope, the liquid falling onto the slope will continue to slide down the slope under gravity and be discharged outside the mounting cavity through the low-positioned water outlet. This prevents liquid from entering the mounting cavity through the gaps around the receiving hole and accumulating inside, which could affect the normal operation of the drive module, thus ensuring the stability of the therapy device.

[0029] 4. As a preferred embodiment of this application, the water-guiding protrusion provided at the top of the first part can guide the water droplets falling on the first part, guide these water droplets to move along the extension direction of the water-guiding protrusion and be discharged from the installation cavity through the water outlet, thereby preventing the water droplets from moving into the installation cavity through the water-guiding slope, which helps to improve the water conductivity of the water-guiding slope.

[0059] like Figure 1 As shown, an upper cover assembly for a respiratory humidification therapy device is installed on the body of the respiratory humidification therapy device. The upper cover assembly includes a cover body 1, which has a mounting part 11 and a control part 12. The mounting part 11 is installed on the body, and the control part 12 is set at an angle to the mounting part 11 and has a control screen 121 extending obliquely. The upper cover assembly also includes a rear cover 2 located between the mounting part 11 and the control part 12. The rear cover 2, the cover body 1, and the body cooperate to form a mounting cavity for installing a drive module.

[0060] The top cover assembly of this application includes a cover 1 having a mounting part 11 and a control part 12. The mounting part 11 is connected to the body of the therapeutic instrument, and the control part 12 is arranged at an angle to the mounting part 11, such that the control screen 121 mounted on the control part 12 extends obliquely, that is, the control screen 121 forms a certain angle with the horizontal plane. Users only need to stand in front of the therapeutic instrument to intuitively obtain information on the control screen 121 and operate the control screen 121 from the front of the instrument. In this way, even when the therapeutic instrument is placed at a certain distance from the operator, such as in the center of a table, the user does not need to move the therapeutic instrument; they can observe and operate the control screen 121 from the edge of the table, thus optimizing the user experience. In addition, the upper cover assembly also includes a rear cover 2 located between the mounting part 11 and the control part 12. The rear cover 2, together with the cover body 1 and the body, forms a mounting cavity, providing a relatively enclosed working environment for the drive module inside the body. On the one hand, this reduces the adverse interference of the external environment on the drive module and helps to improve the working stability of the treatment device. On the other hand, the rear cover 2 and the cover body 1 shield the internal components of the body, preventing the drive module from being exposed to the user's field of vision and helping to optimize the user's sensory experience.

[0061] As a preferred embodiment of this application, such as Figure 1As shown, the rear cover 2 has a first part 21 connected to the control unit 12 and a second part 22 connected to the mounting part 11. The first part 21 and the second part 22 are arranged at an angle to form a gap 3. By configuring the rear cover 2 to include the first part 21 and the second part 22, the rear cover 2 can provide a certain degree of support for the control unit 12, reducing the probability of the control unit 12 deforming downward under its own weight or during long-term operation, and providing a more stable working environment for the control screen 121. In addition, the first part 21 and the second part 22 are arranged at an angle, and a gap 3 is formed between them. When the user needs to move the therapeutic device, he / she can put his / her hand into the gap 3 to lift the therapeutic device, thereby reducing the pressure on the user when moving the therapeutic device.

[0062] Specifically, in this embodiment, the extension direction of the second part 22 is flush with the mounting part 11, one end of the first part 21 is connected to the second part 22, and the other end extends obliquely at an angle to the second part 22, so that the projection of the gap 3 toward the vertical plane has a V-shaped structure.

[0063] As a preferred embodiment of this implementation, such as Figure 2 As shown, the control unit 12 has a receiving hole 122 for mounting the control panel 121, and the first part 21 has a water guiding slope 211 located below the receiving hole 122. The first part 21 has a water outlet 4 communicating with the outside of the mounting cavity at the low position of the water guiding slope 211.

[0064] The receiving hole 122 on the control unit 12 provides a mounting position for the control panel 121, allowing the control panel 121 to be stably mounted on the control unit 12 through the receiving hole 122. The humidification tank, as an important component of the humidification therapy device, heats the water inside the tank using a heating element, causing the water to evaporate. The evaporated water vapor is then delivered to the patient's respiratory tract through the breathing tubing to achieve the purpose of humidification therapy. The humidification tank needs to be frequently refilled or its water changed during operation. Since the humidification tank is usually refilled via a suspended water bag, water may splash during refilling or changing due to operational issues. Water droplets may drip onto the upper cover assembly, or during transport of the humidification therapy device in rainy weather, and as the water drips downwards, it may enter the mounting cavity through the assembly gap between the rear cover 2 and the mounting part 11, or the assembly gap between the rear cover 2 and the control part 12. Water droplets seeping into the assembly gaps will fall onto the water-guiding slope 211 under gravity. Because the water-guiding slope 211 extends obliquely and the water outlet 4 is located at the lower position of the water-guiding slope 211, the liquid falling onto the water-guiding slope 211 will continue to slide down the water-guiding slope 211 under gravity and be discharged outside the mounting cavity through the water outlet 4 located at the lower position. This prevents liquid from entering the mounting cavity through the gaps around the receiving hole 122 and accumulating inside the mounting cavity, which could affect the normal operation of the drive module, thus ensuring the stability of the therapy device's operation.

[0065] Specifically, waterproof foam is provided between the back cover 2 and the control unit 12 or between the back cover 2 and the mounting unit 11.

[0066] As a preferred example in this embodiment, such as Figure 2 As shown, the top of the first part 21 is provided with a water-guiding protrusion 212, which cooperates with the upper surface of the first part 21 to form a water-guiding slope 211. The water-guiding protrusion 212 provided at the top of the first part 21 can guide the water droplets falling on the first part 21, guiding these water droplets to move along the extension direction of the water-guiding protrusion 212 and be discharged from the installation cavity through the water outlet 4, thereby preventing the water droplets from moving into the installation cavity through the water-guiding slope 211, which helps to improve the water conductivity of the water-guiding slope 211.

[0067] This example does not limit the location or number of water inlets 4, which can be adopted in any of the following ways:

[0068] Method 1: For example Figure 4 As shown, the water inlet 4 includes a first water inlet 41 located in the middle of the first part 21, and the water guiding protrusion 212 includes a first water guiding section 2121. One end of the first water guiding section 2121 is connected to the first water inlet 41, and the other end extends towards the high position of the water guiding slope 211 on both sides of the first water inlet 41. By setting the first water inlet 41 in the middle of the first part 21, water droplets falling on the first part 21 can converge towards the first water inlet 41 under the action of the water guiding protrusion 212. This reduces the movement length required for water droplets on the first part 21 to exit the mounting cavity, helps to shorten the residence time of water droplets in the mounting cavity, and helps to improve the working stability of the drive module inside the mounting cavity.

[0069] Preferably, such as Figure 4 As shown, the water outlet 4 also includes second water outlets 42 located on both sides of the first part 21, and the water guiding protrusion 212 also includes a second water guiding section 2122. One end of the second water guiding section 2122 is connected to the first water guiding section 2121, and the other end extends towards the second water outlet 42. By setting the second water guiding section 2122, the guiding area of ​​the water guiding slope 211 for water droplets falling on the first part 21 is increased, reducing the probability that water droplets are not guided by the water guiding slope 211 and accumulate inside the mounting cavity. In addition, the setting of the second water outlet 42 also provides a new discharge channel for water droplets. When the water seepage inside the mounting cavity is serious and a large number of water droplets enter the mounting cavity, the first water outlet 41 and the second water outlet 42 work together to guide and discharge the water droplets inside the mounting cavity, reducing the probability of water droplets accumulating inside the mounting cavity due to untimely discharge.

[0070] This application does not limit the location of the second water inlet 42 or the structural form of the second water intake section 2122, which can be as follows: Figure 4As shown, the second water inlet 42 is located on the side of the first part 21 away from the first water inlet section 2121, and the second water inlet section 2122 gradually extends at an incline from the side closest to the first water inlet section 2121 toward the second water inlet 42; it can also be as follows Figure 11 As shown, the second water inlet 42 is located in the middle of the side of the first part 21. The second water inlet section 2122 is divided into two sections. One section extends inclinedly from the first water inlet section 2121 to the second water inlet 42, and the other section extends inclinedly from the side of the first part 21 away from the first water inlet section 2121 to the second water inlet 42.

[0071] Furthermore, such as Figure 1 , Figure 5 As shown, the upper cover assembly also includes a lifting member 5 rotatably connected to the cover body 1. The cover body 1 is provided with an installation area 6 rotatably connected to the lifting member 5. The second water inlet 42 is located above the installation area 6. There is a water passage gap between the lifting member 5 and the cover body 1. The installation area 6 communicates with the outside through the water passage gap.

[0072] The lifting component 5 provides a lifting position for the transport of the humidification therapy device. When the position of the humidification therapy device needs to be moved, the user can reach into the grip gap 3 with one hand, grasp the lifting component 5 with the other hand, and apply force to lift the therapy device, reducing the transport pressure of the lifting component 5. In addition, the cover 1 is provided with an installation area 6 to facilitate the assembly of the lifting component 5, and the second water outlet 42 is located above the installation area 6. A water passage gap is provided between the lifting component 5 and the cover 1. The water discharged from the second water outlet 42 can flow to the installation area under the action of gravity and flow out of the outside of the device through the water passage gap, eliminating the need to set up a separate discharge channel for the water discharged from the second water outlet 42, which helps to optimize the structural design of the upper cover assembly.

[0073] Preferably, the cover 1 has a bend in the direction of the mounting cavity at the corresponding mounting area 6, which reduces the space occupied by the lifting member 5 on the external space of the cover 1 and helps to maintain the flatness of the appearance surface of the cover assembly.

[0074] Method 2: For example Figure 6 As shown, water inlets 4 are distributed on both sides of the first part 21, and water guiding protrusions 212 extend from the high position of the water guiding slope 211 to the water inlets 4. Setting the number of water inlets 4 to two provides more discharge paths for water droplets on the water guiding slope 211, which helps to reduce the probability of water droplets accumulating in the installation cavity.

[0075] This method does not limit the number or location of the 4 water inlets; they can be as follows: Figure 6 As shown, there are two water inlets 4, located at the middle positions on both sides of the first part 21, with the two ends of the side portion of the first part 21 inclined towards the water inlets 4; it can also be as follows: Figure 12As shown, each side of the first part 21 is provided with two water inlets 4. The water-guiding protrusion 212 is divided into two sections, one section extending along the length of the first part 21 and the other section extending along the width of the first part 21. The water inlets 4 are located at the corner of the water-guiding protrusion 212 and the lowest position of the side of the first part 21, respectively.

[0076] As a preferred embodiment of this application, such as Figure 7 , Figure 8 As shown, the first part 21 has a first mounting hole 2131, and the cover 1 has a second mounting hole 131 that aligns with the first mounting hole 2131. The first part 21 is connected to the cover 1 by sequentially inserting mounting parts 7 into the first mounting hole 2131 and the second mounting hole 131. Preferably, the first mounting hole 2131 and the second mounting hole 131 have matching internal threads, the mounting part 7 is a stud, and the cover 1 and the rear cover 2 are threadedly connected by the stud.

[0077] As a preferred embodiment of this implementation, such as Figure 8 As shown, the first part 21 has a mounting boss 213, which is hollow inside to form a first mounting hole 2131. The cover 1 has a positioning protrusion 13, which is hollow inside to form a second mounting hole 131. The positioning protrusion 13 and the mounting boss 213 abut against each other to make the first mounting hole 2131 and the second mounting hole 131 aligned and connected. The installation of the mounting boss 213 and the positioning boss 13 reduces the difficulty of creating the first mounting hole 2131 and the second mounting hole 131, thus improving the manufacturing efficiency of the cover 1 and the rear cover 2. Furthermore, during the assembly of the rear cover 2 and the cover 1, the assembler only needs to control the mounting boss 213 and the positioning boss 1 to abut against each other to achieve communication between the first mounting hole 2131 and the second mounting hole 131, eliminating the need for precise alignment of the relative positions of the first and second mounting holes 2131 and reducing the assembly difficulty of the rear cover 2 and the cover 1. In addition, the lengths of the first and second mounting holes 2131 can be adjusted by adjusting the lengths of the positioning boss 13 and the mounting boss 213, reducing the thickness requirements of the rear cover 2 and the cover 1 and helping to optimize the structural design of the upper cover assembly.

[0078] As a preferred example in this embodiment, such as Figure 7 , Figure 8As shown, the first part 21 is provided with a first positioning step 214, and the cover 1 is provided with a second positioning step 14 adapted to the first positioning step 214. When the first positioning step 214 and the second positioning step 14 are engaged, the first mounting hole 2131 and the second mounting hole 131 are aligned. The setting of the first positioning step 214 and the second positioning step 14 increases the engagement area of ​​the cover 1 and the rear cover 2. When the upper cover assembly is subjected to external force and the cover 1 and the rear cover 2 tend to move relative to each other, the engaging first positioning step 214 and the second positioning step 14 can block the relative position of the cover 1 and the rear cover 2 to a certain extent, which helps to ensure the stability of their relative position. On the other hand, when assembling the cover 1 and the rear cover 2, it is only necessary to engage the first positioning step 214 with the second positioning step 14 to realize the positioning of the positioning protrusion 13 and the mounting protrusion 213, thereby realizing the alignment and communication of the first mounting hole 2131 and the second mounting hole 131, which helps to improve the assembly speed of the rear cover 2 and the cover 1.

[0079] As a preferred embodiment of this application, such as Figure 7 , Figure 9 As shown, the second part 22 is provided with a first limiting hole 221, and the upper cover assembly also includes a fixing frame 8 connected to the cover body 1. The fixing frame 8 is provided with a first limiting protrusion 81, which abuts against the inner wall of the first limiting hole 221. By providing the first limiting hole 221 in the second part 22 and the first limiting protrusion 81 in the fixing frame 8 respectively, when the rear cover 2 is subjected to external force and tends to move relative to the fixing frame 8, the first limiting protrusion 81 cooperates with the first limiting hole 221 to limit the displacement of the rear cover 2 and the fixing frame 8. The fixing frame 8 is also connected to the cover body 1, which simultaneously improves the stability of the relative position of the cover body 1 and the rear cover 2.

[0080] As a preferred embodiment of this implementation, such as Figure 9 As shown, the first limiting protrusion 81 includes a first column 811 located within the first limiting hole 221 and a second column 812 located below the first column 811. The cross-sectional area of ​​the second column 812 is larger than that of the first column 811. The second part 22 is provided with an annular sleeve 222 below the limiting hole, and the second column 812 abuts against the inner wall of the annular sleeve 222. By setting the first column 811 with a smaller cross-sectional area than the second column 812, the first limiting protrusion 81 can be inserted into the annular sleeve 222 more easily. Furthermore, the first column 811 abuts against the inner wall of the limiting hole, and the second column 812 abuts against the inner wall of the annular sleeve 222, achieving a double abutment between the first limiting protrusion 81 and the limiting hole and the annular sleeve 222, which helps to enhance the stability of the relative position between the rear cover 2 and the fixing bracket 8.

[0081] As a preferred example in this embodiment, such as Figure 9As shown, an annular sealing rib 9 is fitted around the outer periphery of the first column 811. The annular sealing rib 9 abuts against the inner wall of the annular sleeve 222 and the outer wall of the first column 811. The annular sealing rib 9 further enhances the tightness of the abutment between the first limiting protrusion 81 and the annular sleeve 222, thereby further strengthening the stability of the relative position between the rear cover 2 and the fixing bracket 8. At the same time, it can achieve waterproof function, preventing water from entering the installation cavity from the first limiting hole 221.

[0082] As another preferred embodiment of this implementation, such as Figure 3 As shown, the second part 22 is provided with a second limiting hole 223 that is offset from the first limiting hole 221, and the fixing frame 8 is also provided with a second limiting protrusion 82, which abuts against the inner wall of the second limiting hole 223. The setting of the second limiting hole 223 and the second limiting protrusion 82 further enhances the stability of the relative position between the fixing frame 8 and the rear cover 2. The first limiting hole 221 and the first limiting protrusion 81, and the second limiting hole 223 and the second limiting protrusion 82 cooperate to provide great assurance for the stability of the fixing frame 8 and the rear cover 2.

[0083] Preferably, the bottom of the mounting bracket 8 has multiple component mounting positions for mounting the drive module. These mounting positions at the bottom of the mounting bracket 8 provide a mounting platform for the drive module, eliminating the need for a separate mounting component 7 and helping to optimize the structural layout of the upper cover assembly. Furthermore, the mounting bracket 8, in addition to enhancing the connection stability between the rear cover 2 and the cover body 1, further integrates the function of providing mounting positions for the drive module, resulting in a high degree of functional integration and optimizing the structural design of the upper cover assembly.

[0084] Furthermore, such as Figure 10 As shown, the bottom of the cover 1 has an opening for the fixing bracket 8 to be inserted from the bottom of the cover 1. The fixing bracket 8 has a guide groove 83, and the cover 1 has a guide slide 15 extending vertically, which abuts against the inner wall of the guide groove 83. The opening at the bottom of the cover 1 allows the fixing bracket 8 to be inserted from the bottom of the cover 1. The guide groove 83 and guide slide 15 eliminate the need for assemblers to calibrate the relative positions of the fixing bracket 8 and the cover 1; during assembly, only the guide slide 15 and guide groove 83 need to be aligned, improving assembly efficiency. Furthermore, the guide slide 15 and guide groove 83 provide motion guidance for the fixing bracket 8 to be inserted into the bottom of the cover 1, preventing jamming between the fixing bracket 8 and the cover 1 due to uneven force applied by the assembler or other factors during assembly, thus reducing the assembly difficulty of the fixing bracket 8.

[0085] As a preferred embodiment of this application, such as... Figure 5As shown, the top of the mounting part 11 is provided with a water-blocking rib 10 arranged circumferentially, and the water-blocking rib 10 extends vertically and abuts against the inner wall of the rear cover 2.

[0086] The water-blocking rib 10 can prevent water droplets from entering the machine body through the gap between the rear cover 2 and the mounting part 11, reducing the probability of water droplets entering the mounting cavity and helping to improve the waterproof effect of the top cover assembly.
