Description

Technical Field

[0001] This utility model relates to the field of automatic dispensing technology, and in particular to an additive container. Background Technology

[0002] The prior art disclosed in CN110158276A is a "treatment agent dispensing device and washing machine", in which a waterproof and breathable structure is set on the treatment agent box and / or the cover, and there are two implementation methods: 1. The sealing block is set on the treatment agent box, or the sealing film is set on the cover, or the sealing film is set on the treatment agent box; 2. The sealing block is set on the cover, or the sealing block is set on the treatment agent box, or the sealing film is set on the cover. In both of the above implementation methods, regardless of whether the sealing film is set on the cover or the treatment agent box, dust or condensation will accumulate on the sealing film under long-term use, thereby affecting the performance of the sealing film, causing the treatment agent box to be under inconsistent pressure with the outside, resulting in the dispensing mechanism being unable to extract the treatment agent or having a reduced extraction capacity. Utility Model Content

[0003] The purpose of this invention is to provide an additive container that solves the problem of condensation or water accumulation on the breathable membrane, thus ensuring that the breathable membrane's performance is not affected by dust or condensation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an additive container, comprising a container body and a breathable membrane assembly installed on the container body, a protective cover covering the breathable membrane assembly on the container body, a breathable gap between the protective cover and the breathable membrane assembly, a breathable channel on or between the protective cover and / or the container body, and the inner cavity of the container body communicating with the external atmosphere through the breathable membrane assembly, the breathable gap and the breathable channel.

[0005] After adopting the above technical solution, the present invention has the following advantages: A protective cover is provided on the container body for covering the breathable membrane assembly. The protective cover can effectively prevent dust from falling onto the breathable membrane assembly. Due to temperature differences or humidity changes, condensation may accumulate on the outer wall of the protective cover. The protective cover can prevent the condensation on the outer wall from dripping onto the breathable membrane assembly, thus preventing the accumulation of condensation from affecting the performance of the breathable membrane assembly. The breathable membrane assembly is used to prevent moisture from evaporating from the container body, so that the additives in the container body will not dry and solidify for a long time, avoiding the failure of the automatic dispensing container function and the difficulty of cleaning the container body. A permeable gap is provided between the protective cover and the permeable membrane assembly, and a permeable channel is provided on or between the protective cover and / or the container body. The structure of the permeable membrane assembly allows gas molecules to communicate with the outside atmosphere inside the container body through the permeable gap and the permeable channel to achieve the purpose of ventilation. However, water molecules cannot flow, thus avoiding water loss and effectively preventing the additive from drying out and solidifying. When the automatic dispensing container extracts additives, causing the negative pressure inside the container body to be too low, external gas can enter the container body through the permeable membrane assembly to achieve a balance of air pressure inside and outside the container body. This prevents the negative pressure inside the container body from being too high, which could cause the automatic dispensing container to be unable to extract additives or have a reduced extraction capacity.

[0006] Furthermore, the protective cover and / or the container body are provided with drainage channels for outward drainage. After the container body is installed in place, the drainage channels are located at the bottom of the venting gap and are lower than the venting membrane assembly, while the venting channels are located at the top of the venting gap and are higher than the venting membrane assembly after the container body is installed in place.

[0007] Using the aforementioned technical solution, during use, condensation may form on the outer wall of the container body or the inner wall of the protective cover due to temperature differences or humidity changes. Therefore, the protective cover and / or the container body are provided with drainage channels for draining condensation to prevent condensation accumulation from affecting the performance of the breathable membrane assembly. The drainage channel is located at the bottom of the breathable gap and below the breathable membrane assembly, allowing condensation to be discharged through the drainage channel. The breathable channel is located at the top of the breathable gap and above the breathable membrane assembly, allowing gas to communicate with the outside atmosphere through the breathable gap and the breathable channel. By setting it above the breathable membrane assembly, part of the breathable membrane assembly can still be covered by the protective cover, preventing dust from entering and falling directly onto the breathable membrane assembly during long-term use. The drainage channel is located at the bottom of the breathable gap and below the breathable membrane assembly, allowing condensation to naturally flow down the outer wall of the container body or the inside of the protective cover and be discharged smoothly, avoiding pressure imbalance inside and outside the container caused by condensation accumulation.

[0008] Furthermore, the ventilation channel is located at the bottom of the ventilation gap and is reused as a drainage channel.

[0009] By adopting the aforementioned technical solution, the ventilation channel is set at the bottom of the ventilation gap and reused as a drainage channel, which can realize the dual functions of ventilation and drainage, simplify the structure, reduce the amount of materials used, and reduce production costs.

[0010] Furthermore, the ventilation channel includes a ventilation groove or ventilation hole penetrating the protective cover; or, the ventilation channel includes a ventilation groove or ventilation hole provided on the outer wall of the container body; or, the protective cover is provided with a first groove, the outer wall of the container body is provided with a second groove, and the first groove and the second groove are joined together to form the ventilation hole of the ventilation channel.

[0011] Furthermore, the container body is provided with an installation through hole, and the breathable membrane assembly also includes a breathable membrane, a membrane support and a seal. The breathable membrane is fixed to the membrane support, and the membrane support is fixedly installed in the installation through hole and sealed by the seal.

[0012] Using the aforementioned technical solution, the container body is provided with an installation through hole, which provides an installation position for the breathable membrane assembly. The membrane support is used to fix the breathable membrane, and the sealing element is used to seal the gap between the membrane support and the installation through hole to prevent moisture and impurities from entering the container. This structural design not only allows the breathable membrane to be firmly installed in the installation through hole, but also simplifies the installation process. At the same time, the membrane support, the installation through hole, and the sealing element are all detachable, which facilitates the maintenance and replacement of the breathable membrane.

[0013] Furthermore, the seal is a ring-shaped structure, fitted around the outer periphery of the membrane support. The outer end of the seal has a first flange, and the outer end of the membrane support has a second flange. The second flange presses the first flange against the end face of the mounting through hole.

[0014] Using the aforementioned technical solution, the annular seal can better fit the shape of the mounting through hole, making the seal tighter and improving the sealing effect. The first flange is set at the outer end of the seal to form a pressing contact with the end face of the membrane support and the mounting through hole; the second flange is set at the outer end of the membrane support to press the first flange against the end face of the mounting through hole, ensuring the reliability of the seal. This not only improves the sealing effect but also enhances the connection strength between the seal and the membrane support and the mounting through hole, preventing additives from leaking from here.

[0015] Furthermore, the protective cover is provided with a pressure rib that presses against the membrane support and fixes the membrane support to the installation through hole.

[0016] Using the aforementioned technical solution, the pressure ribs press the membrane support onto the mounting through hole, enhancing the connection strength between the membrane support and the mounting through hole. When the membrane support is pressed into the mounting through hole, the annular seal can fit better into the mounting through hole, improving the sealing performance.

[0017] Furthermore, the container body is installed on the automatic dispensing container at a downward angle from the tail to the head, so that the head of the container body is lower than the tail. The head of the container body is provided with a liquid outlet, and the venting membrane assembly is higher than the liquid outlet. The venting membrane assembly is located at the head or tail of the container body.

[0018] Using the aforementioned technical solution, the breathable membrane component can be set at the head or tail of the container body above the liquid outlet, so as to minimize the contact between the additive and the breathable membrane component, thus ensuring the dryness and normal breathability of the breathable membrane component.

[0019] Furthermore, the breathable membrane assembly is installed laterally on the longitudinal sidewall of the container body.

[0020] By adopting the aforementioned technical solution, the breathable membrane component is installed laterally on the longitudinal side wall of the container body, which can provide a flow path for condensate. Under the action of gravity, the condensate will flow along the side wall and be discharged from the drainage channel. These natural drainage methods are simpler and effectively prevent condensate from accumulating on the breathable membrane component.

[0021] Furthermore, the container body is provided with a mounting groove for detachable installation of the protective cover, and the outer edge of the protective cover is flush with the edge of the mounting groove.

[0022] Using the aforementioned technical solution, the mounting groove is used to detachably connect the container body and the protective cover, making it convenient for users to replace the ventilated components. The outer edge of the protective cover is flush with the edge of the mounting groove, making the overall appearance of the container body neater and more aesthetically pleasing. It also makes it easier for users to install the container body into the mounting cavity without worrying about misalignment or interference. Attached Figure Description

[0031] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0032] like Figures 1 to 4 As shown, an additive container includes a container body 1 and a breathable membrane assembly 2 installed on the container body 1. The container body 1 is provided with a protective cover 21 covering the breathable membrane assembly 2. There is a breathable gap 11 between the protective cover 21 and the breathable membrane assembly 2. The protective cover 21 is provided with a breathable channel 211. The inner cavity of the container body 1 is connected to the outside atmosphere through the breathable membrane assembly 2, the breathable gap 11 and the breathable channel 211.

[0033] A protective cover 21 is provided on the container body 1 to cover the breathable membrane assembly 2. The protective cover 21 can effectively prevent dust from falling onto the breathable membrane assembly 2. Due to temperature differences or humidity changes, condensation may accumulate on the outer wall of the protective cover 21. The protective cover 21 can prevent the condensation on the outer wall from dripping onto the breathable membrane assembly 2, thus preventing the accumulation of condensation from affecting the performance of the breathable membrane assembly 2. The breathable membrane assembly 2 is used to prevent moisture from evaporating from the container body 1, so that the additives in the container body 1 will not dry and solidify for a long time, avoiding the failure of the automatic dispensing container function and the difficulty of cleaning the container body 1. A permeable gap 11 is provided between the protective cover 21 and the permeable membrane assembly 2. The protective cover 21 is provided with a permeable channel 211. The structure of the permeable membrane assembly 2 allows gas molecules inside the container body 1 to communicate with the outside atmosphere through the permeable gap 11 and the permeable channel 211 to achieve the purpose of ventilation. However, water molecules cannot flow, thus avoiding water loss and effectively preventing the additive from drying out and solidifying. When the automatic dispensing container extracts the additive, causing the negative pressure inside the container body 1 to be too low, external gas can enter the container body 1 through the permeable membrane assembly 2 to achieve the balance of air pressure inside and outside the container body 1. This prevents the negative pressure inside the container body 1 from being too high, which could cause the automatic dispensing container to be unable to extract the additive or have a reduced extraction capacity.

[0034] Specifically, the breathable membrane component 2 includes a breathable membrane 24, which is made of a breathable but waterproof material, such as nano-polyethylene breathable material, polyester breathable material, polytetrafluoroethylene material, etc.

[0035] Specifically, the ventilation channel 211 also has the following implementation methods:

[0036] 1. The ventilation channel 211 can be a ventilation groove that penetrates the protective cover 21;

[0037] 2. The ventilation channel 211 can be a ventilation hole that penetrates the protective cover 21;

[0038] 3. The ventilation channel 211 can be a ventilation groove provided on the outer wall of the container body 1;

[0039] 4. The ventilation channel 211 can be a ventilation hole provided on the outer wall of the container body 1;

[0040] 5. A first groove is provided on the protective cover 21, and a second groove is provided on the outer wall of the container body 1. The first groove and the second groove are joined together to form a vent hole for the venting channel 211.

[0041] Specifically, in this embodiment, the protective cover 21 is provided with a drainage channel for outward drainage. After the container body 1 is installed in place, the drainage channel is located at the bottom of the ventilated gap 11 and is lower than the ventilated membrane assembly 2. The ventilated channel 211 is located at the top of the ventilated gap 11 and is higher than the ventilated membrane assembly 2 after the container body 1 is installed in place.

[0042] During use, due to temperature differences or humidity changes, condensation may form on the outer wall of the container body 1 or the inner wall of the protective cover 21. Therefore, the protective cover 21 is provided with a drainage channel for draining condensation to prevent condensation from accumulating and affecting the performance of the breathable membrane assembly 2. The drainage channel is located at the bottom of the breathable gap 11 and is lower than the breathable membrane assembly 2. Condensation can be discharged through the drainage channel. The breathable channel 211 is located at the top of the breathable gap 11 and is higher than the breathable membrane assembly 2. Gas can communicate with the outside atmosphere through the breathable gap 11 and the breathable channel 211. By setting it higher than the breathable membrane assembly 2, part of the breathable membrane assembly 2 can still be covered by the protective cover 21 to prevent dust from entering and falling directly onto the breathable membrane assembly 2 during long-term use. The drainage channel is located at the bottom of the breathable gap 11 and is lower than the breathable membrane assembly 2, so that condensation can flow naturally down the outer wall of the container body 1 or the inside of the protective cover 21 and be discharged smoothly, avoiding pressure imbalance inside and outside the container caused by condensation accumulation.

[0043] In another embodiment, the drainage channel may also be provided on the outer wall of the container body 1.

[0044] Preferably, the ventilation channel 211 is located at the bottom of the ventilation gap 11 and is reused as a drainage channel.

[0045] By placing the ventilation channel 211 at the bottom of the ventilation gap 11 and reusing it as a drainage channel, the dual functions of ventilation and drainage can be achieved, which can simplify the structure, reduce the amount of materials used, and reduce production costs.

[0046] The container body 1 is provided with an installation through hole 12. The breathable membrane assembly 2 also includes a membrane support 22 and a sealing element 23. The breathable membrane 24 is fixed to the membrane support 22. The membrane support 22 is fixedly installed in the installation through hole 12 and sealed by the sealing element 23.

[0047] The container body 1 is provided with an installation through hole 12, which provides an installation position for the breathable membrane assembly 2. The membrane support 22 is used to fix the breathable membrane 24, and the seal 23 is used to seal the gap between the membrane support 22 and the installation through hole 12 to prevent moisture and impurities from entering the container. This structural design not only allows the breathable membrane 24 to be firmly installed in the installation through hole 12, but also simplifies the installation process. At the same time, the membrane support 22, the installation through hole 12 and the seal 23 are all detachably connected, which facilitates the maintenance and replacement of the breathable membrane 24.

[0048] The sealing element 23 has an annular structure and is fitted around the outer periphery of the membrane support 22. The outer end of the sealing element 23 is provided with a first flange 231, and the outer end of the membrane support 22 is provided with a second flange 221. The second flange 221 presses the first flange 231 against the end face of the mounting through hole 12.

[0049] The annular seal 23 can better fit the shape of the mounting through hole 12, making the seal tighter and improving the sealing effect. The first flange 231 is set at the outer end of the seal 23 to form a pressing contact with the end face of the membrane support 22 and the mounting through hole 12. The second flange 221 is set at the outer end of the membrane support 22 to press the first flange 231 against the end face of the mounting through hole 12, ensuring the reliability of the seal. This not only improves the sealing effect but also enhances the connection strength between the seal 23 and the membrane support 22 and the mounting through hole 12, preventing the additive from leaking out from here.

[0050] The protective cover 21 is provided with a pressure rib 212 that presses against the membrane support 22 and fixes the membrane support 22 to the mounting through hole 12.

[0051] The pressure rib presses the membrane support 22 tightly onto the mounting through hole 12, enhancing the connection strength between the membrane support 22 and the mounting through hole 12. When the membrane support 22 is pressed tightly onto the mounting through hole 12, the annular seal 23 can fit better into the mounting through hole 12, improving the sealing performance.

[0052] The container body 1 is installed on the automatic dispensing container at an angle from the tail to the head, so that the head of the container body 1 is lower than the tail. The head of the container body 1 is provided with a liquid outlet 13, and the breathable membrane assembly 2 is higher than the liquid outlet 13. The breathable membrane assembly 2 is located at the head of the container body 1.

[0053] The breathable membrane component 2 can be set at the head of the container body 1 above the liquid outlet 13, so that the additives do not come into contact with the breathable membrane component 2 as much as possible, thus ensuring the dryness and normal breathability of the breathable membrane component 2.

[0054] Preferably, the breathable membrane assembly 2 can also be disposed at the tail of the container body 1 above the liquid outlet 13.

[0055] Preferably, the breathable membrane assembly 2 is installed laterally on the longitudinal sidewall of the container body 1.

[0056] Installing the breathable membrane component 2 horizontally on the longitudinal side wall of the container body 1 provides a flow path for condensate. Under the action of gravity, the condensate will flow along the side wall and be discharged from the drainage channel. This natural drainage method is simpler and effectively prevents condensate from accumulating on the breathable membrane component 2.

[0057] In other embodiments, the breathable membrane component 2 of this invention can be set at any position as needed, and is not limited to the specific position mentioned in this embodiment.

[0058] The container body 1 is provided with a mounting groove 14 that can be detachably installed with the protective cover 21, and the outer edge of the protective cover 21 is flush with the edge of the mounting groove 14.

[0059] The mounting slot 14 is used to detachably connect the container body 1 and the protective cover 21, making it convenient for users to replace the ventilated components. The outer edge of the protective cover 21 is flush with the edge of the mounting slot 14, making the overall appearance of the container body 1 neater and more beautiful. It also makes it easier for users to install the container body 1 into the mounting cavity without worrying about misalignment or interference.

[0060] In the above embodiments, the venting channel 211, venting hole, venting groove and drainage channel mentioned above will not cause the additives in the container body 1 to leak.

[0061] According to the above embodiments, such as Figure 5 As shown, taking a washing machine as an example, the washing machine has an installation cavity. The container body 1 is an automatically dispensing detergent container for insertion into the installation cavity. The head of the container body 1 has a liquid outlet 13 and a liquid dispensing assembly 3 that is inserted and matched with the liquid outlet 13. The outer edge of the liquid outlet 13 has an installation rib 15. The liquid dispensing assembly 3 includes a valve cover 31 and a valve body 32. The valve body 32 extends into the container body 1 through the liquid outlet 13. The valve cover 31 is connected to the installation rib 15 to fix the valve body 32. The container body 1 is installed horizontally on the... The mounting cavity has a foolproof structure that matches the outer peripheral surface of the mounting rib 15 and the valve cover 31, so that the valve body 32 faces a predetermined direction after being fixed. The foolproof structure includes a hook 151 and a groove 311. The mounting rib 15 and the valve cover 31 are provided with a hook 151 and a groove 311 respectively. Multiple hooks 151 and grooves 311 are unevenly distributed along the outer peripheral surface of the mounting rib 15. The hooks 151 and grooves 311 are engaged one-to-one to prevent foolproof installation of the valve cover 31 and the mounting rib 15.

[0062] In this embodiment, the hook 151 is provided on the mounting rib 15, and the slot 311 is provided on the valve cover 31.

[0063] A liquid outlet 13 is provided at the head of the container body 1. The valve body 32 extends into the interior of the container body 1 through the liquid outlet 13 to discharge the additive inside the container body 1. The valve cover 31 is used to connect with the mounting rib 15 and fix the valve body 32, ensuring the stability of the valve body 32 inside the container body 1 and avoiding loosening due to external factors. This helps to enhance the sealing between the liquid outlet component 3 and the container body 1. The valve cover 31 is installed first at the liquid outlet 13 of the container body 1, and then the valve body 32 is fixed on the valve cover 31, making the installation and fixing of the valve body 32 on the container body 1 more convenient. The valve body 32 is fixedly connected by the valve cover 31, which improves the stability of the valve body 32 installed on the container body 1. At the same time, the fixed connection between the valve cover 31 and the valve body 32 improves the sealing between the valve body 32 and the hole wall of the liquid outlet 13. In addition, the valve body 32 can also accurately control the amount of additive, solving the problem that users need to add additives manually based on experience, reducing workload and avoiding the problem of additive waste.

[0064] The container body 1 is installed horizontally in the mounting cavity, reducing the height space occupied by the container body 1 on the garment processing equipment, which facilitates the arrangement of various components in the garment processing equipment. When the valve cover 31 is installed at the liquid outlet 13 of the container body 1, the valve cover 31 is installed by the mounting rib 15. The valve cover 31 and the mounting rib 15 are positioned by the snap-fit ​​of the hook 151 and the slot 311, so that the valve body 32 faces the predetermined direction after installation. The snap-fit ​​of the hook 151 and the slot 311 reduces the difficulty of determining the installation position when installing the valve cover 31 and the mounting rib 15. The hook 151 and the slot 311 are unevenly distributed around the circumference, so that when the hook 151 and the slot 311 are matched one by one, there is only one snap-fit ​​method, avoiding installation errors.

[0065] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
