Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of household appliances, and particularly relates to a frying machine with adjustable exhaust volume. BACKGROUND

[0002] During the cooking process, the frying machine generates steam, flue gas and the like. With the increase of the pressure in the cooking cavity of the frying machine, exhaust is needed through the exhaust valve arranged on the pot cover to avoid excessive pressure. Of course, the demand for exhaust volume is inconsistent at different stages of the cooking process. For example, at the initial stage of cooking, to achieve rapid heating and reduce energy consumption, the exhaust volume needs to be reduced as much as possible. With the gradual ripening of food, according to different cooking food, the exhaust volume needs to be adjusted appropriately to meet the needs of different food for moisture and ripening degree, and to improve the cooking taste of food. However, the exhaust volume of the existing frying machine is not adjustable or the adjustment of the exhaust volume is limited, which cannot meet the demand for multiple exhaust volumes.

[0003] For example, the prior art discloses a frying machine with adjustable exhaust volume, which comprises a pot body, a pot cover and a stirrer. The pot cover is combined with the pot body to form a cooking cavity. An exhaust valve for exhausting steam in the cooking cavity is arranged on the pot cover. The exhaust valve comprises a static valve plate and a dynamic valve plate arranged in layers. The static valve plate is fixed on the pot cover, and the dynamic valve plate is rotationally connected to the static valve plate. The static valve plate is provided with an exhaust part, and the exhaust part comprises at least one first exhaust hole. The dynamic valve plate rotates relative to the static valve plate to adjust the exhaust volume of the exhaust part. The adjustment of the exhaust volume in the above-mentioned scheme is achieved by arranging the static valve plate and the dynamic valve plate in layers, and adjusting the number of exhaust holes actually used for exhaust by overlapping or covering the positions of the exhaust holes. This structure has limited control over the exhaust volume and cannot maximize the use of exhaust holes for exhaust, so the exhaust is not good. Especially in the rapid exhaust stage, the frying machine in this technical scheme cannot achieve rapid exhaust, and the retained steam may cause the processed food to become wet and soft, thereby affecting the cooking taste. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a frying machine with adjustable exhaust volume to solve the technical problem that the exhaust volume adjustment of the existing frying machine is limited and cannot meet the demand for multiple exhaust volumes, thereby causing poor cooking effect.

[0005] The technical scheme adopted by the present application is as follows:

[0006] A frying machine with adjustable exhaust volume comprises a pot cover and an exhaust valve arranged on the pot cover. The exhaust valve comprises a valve seat and a valve cover. The valve seat is provided with an exhaust passage, and the valve cover is provided with an exhaust hole. The valve cover is movably arranged on the valve seat to have a covering state of covering at least part of the exhaust passage and an uncovering state of completely opening the exhaust passage.

[0007] Different recipes require different cooking environments, such as stewing, steaming or pressure cooking. The design of the exhaust valve in the present application enables the wok to adapt to multiple cooking methods. Specifically, the valve cover in the present application is movably arranged on the valve seat, so the valve cover can move relative to the valve seat to at least partially cover the exhaust passage or completely open the exhaust passage, thereby facilitating the user to control the amount of steam discharged during cooking according to the cooking requirements, so that the wok in the present application can adapt to the needs of different cooking stages and different cooking food for exhaust volume, providing more flexible cooking control and improving the cooking taste of food. Moreover, by reasonably controlling the exhaust volume, energy loss can be reduced, cooking efficiency can be improved, and energy can be saved. Furthermore, during the cooking process, especially in a high temperature and high humidity environment, food and steam may overflow from the edge of the pot cover. By adjusting the state of the valve cover, the overflow can be effectively prevented, and the cooking environment can be kept clean. In addition, the valve cover in the present application can be moved to a fully open exhaust passage state to enable the pot cover to quickly exhaust steam, achieve steam discharge in a short time, rapidly release the pressure in the pot, and reduce the accumulation of condensed water on the pot cover. For example, in the case of rapid stir-frying or rapid cooling, completely opening the exhaust passage helps to improve the cooking efficiency.

[0008] The exhaust valve further comprises a vertical shaft arranged on one of the valve seat and the valve cover, and a rotating hole arranged on the other of the valve seat and the valve cover, the valve cover swings around the vertical shaft to switch between the covering state and the uncovering state.

[0009] In the technical solution, the valve seat and the valve cover are connected by the vertical shaft, and when the valve cover is rotated, the rotation angle of the user's wrist is small, improving the comfort of operation. In addition, when the temperature is high, the user can directly push the valve cover with a common kitchen utensil such as chopsticks to achieve the swing of the valve cover, and the user's hand and wrist do not need to pass through the exhaust passage, greatly reducing the risk of being scalded. Moreover, during the rotation of the valve cover around the vertical shaft to switch states, the valve cover can have different covering areas of the exhaust passage before completely opening the exhaust passage, improving the diversity of exhaust volume adjustment, thereby better serving different cooking materials and improving the cooking effect.

[0010] One of the valve seat and the valve cover is provided with a stop portion, and the other is provided with a limiting portion, the stop portion and the limiting portion can abut along the rotation path of the valve cover to limit the rotation angle of the valve cover.

[0011] In the technical solution, the rotation angle of the valve cover can be limited by the stop cooperation of the stop portion and the limiting portion, avoiding 360° rotation around the vertical shaft, so that the user can rotate the valve cover to the initial state of covering the valve seat without special attention, improving the user experience.

[0012] One of the valve seat and the valve cover is provided with a sealing element, and the other is provided with an abutting portion, the sealing element is provided with an outer sealing lip and an inner sealing lip, and a sealing groove with an opening is formed between the outer sealing lip and the inner sealing lip, and the abutting portion abuts and seals with the sealing groove.

[0013] In the technical solution, one of the valve seat and the valve cover is additionally provided with a sealing element, and the other is additionally provided with an abutting portion, so that the valve seat and the valve cover are abutted and sealed in the initial state (the state in which the valve cover does not move relative to the valve seat). On the one hand, it can avoid the steam, oil fume, etc. in the cooking process from overflowing through the joint position of the valve seat and the valve cover to increase the cleaning difficulty of the joint position. On the other hand, it can keep the valve cover in a fixed position, such as a position in which the valve cover does not work relative to the valve seat, or a position in which the valve cover swings to a certain angle relative to the valve seat and the exhaust passage is not completely opened, by the frictional resistance between the sealing element and the abutting portion in the cooking process, so as to avoid the valve cover from swinging freely under the pushing action of the steam and the flue gas, and ensure that the valve cover can be kept in the position required by the user. In addition, there may be a situation in which the user needs to open the cover to observe the internal cooking state in the cooking process. The position of the valve cover can be fixed by the frictional resistance between the sealing element and the abutting portion, so as to avoid the valve cover from swinging under the action of the weight and causing the overflow of condensed water, etc.

[0014] The exhaust valve further comprises a horizontal shaft provided in one of the valve seat and the valve cover, and a rotating hole provided in the other of the valve seat and the valve cover, and the valve cover swings around the horizontal shaft to switch between the cover state and the uncover state.

[0015] In the technical solution, the valve seat and the valve cover are rotationally connected through the horizontal shaft. In the case that the space of the pot cover is limited, the valve cover rotates around the horizontal shaft to switch states, so that the valve cover does not interfere with other components (such as a handle, a visual window, etc.) on the pot cover during the rotation process, and the space above the pot cover can be used to switch the state of the valve cover, which is convenient, fast and easy to operate.

[0016] The valve cover and the valve seat are detachably connected, and the valve cover can be taken off relative to the valve seat to switch between the cover state and the uncover state.

[0017] In the technical solution, the detachable connection between the valve cover and the valve seat facilitates the user to detach the valve cover to thoroughly clean the valve cover and the valve seat, so that the cleaning and maintenance work becomes easier, and helps to maintain the long-term performance and hygiene standard of the exhaust valve. In addition, the detachable connection can avoid the space limitation of the pot cover during the state switching process of the valve cover, so that the exhaust valve in the application can be applied to more types of pot covers.

[0018] The valve cover comprises a cover body and an exhaust part connected with the cover body, the exhaust hole is arranged on the exhaust part, and the exhaust part is sunken relative to the top of the cover body to form a liquid collecting groove cooperated by the exhaust part and the cover body.

[0019] In the technical solution, the exhaust part is sunken relative to the top of the cover body, so that the liquid collecting groove is formed cooperated by the exhaust part and the cover body, the liquid generated by condensation of the steam discharged outside can be accumulated in the liquid collecting groove, the probability of liquid discharged from the valve cover to the remaining area of the pot cover is reduced, the pollution area is reduced, and the cleaning burden of the user is reduced.

[0020] The exhaust part is upwardly raised to form a drainage surface with an intermediate height and a peripheral low on the inner surface and the outer surface of the exhaust part.

[0021] In the technical solution, the exhaust part is upwardly raised to increase the structural strength of the valve cover to a certain extent, avoid deformation of the valve cover under external force and high-temperature cooking environment, prolong the service life of the valve cover, and improve the stability and reliability of the valve cover exhaust. The drainage surface formed on the outer surface of the valve cover by upwardly raising the exhaust part can drain the condensed water to the edge of the liquid collecting groove to avoid the condensed water blocking the exhaust hole on the valve cover and ensure the exhaust efficiency. The drainage surface formed on the inner surface of the valve cover by upwardly raising the exhaust part can break the bubbles of the soup rising up during cooking, reduce the probability of soup overflow, and reduce the cleaning burden of the user.

[0022] The inner diameter of the liquid collecting groove increases from bottom to top to form a flared structure.

[0023] In the technical solution, the liquid collecting groove has a flared structure with an inner diameter increasing from bottom to top, which can facilitate the user to clean the liquid collecting groove and avoid cleaning dead angles.

[0024] The valve cover is provided with a plurality of exhaust holes.

[0025] In the technical solution, a plurality of exhaust holes are arranged on the valve cover to increase the stability and exhaust efficiency of the exhaust, especially in the initial state of the valve cover covering the exhaust passage, stable exhaust can be achieved.

[0038] In order to more clearly illustrate the overall concept of the present application, the following will be described in detail with reference to the accompanying drawings.

[0039] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below. It should be noted that the embodiments of the present application and the features in each embodiment can be combined with each other without conflict.

[0043] As shown in Figure 1 and Figure 2 An adjustable exhaust capacity frying machine includes a pot cover 1 and an exhaust valve provided on the pot cover 1. The exhaust valve includes a valve seat 3 and a valve cover 2. The valve seat 3 is provided with an exhaust passage 31, and the valve cover 2 is provided with an exhaust hole 23. The valve cover 2 is movably arranged on the valve seat 3 to have a covering state of at least partially covering the exhaust passage 31 and an uncovering state of completely opening the exhaust passage 31.

[0044] The covering state in this application should be interpreted broadly. Since the valve cover 2 itself is provided with an exhaust hole 23, it cannot completely cover the exhaust passage 31, that is, in the case where the valve cover 2 is closed to the valve seat 3 and does not move relative to the valve seat 3, as shown in Figure 2 , through the exhaust hole 23 provided on the valve cover 2, the exhaust can still be realized through the exhaust hole 23. For the convenience of description, the state of the valve cover 2 not moving relative to the valve seat 3 can be referred to as the initial state. Therefore, the covering state in this application includes the initial state, and also includes the state of the valve cover 2 moving relative to the valve seat 3 to further open the exhaust passage 31 in the concept of space. The uncovering state in this application refers to the state that the valve cover 2 moves to one side of the valve seat 3, as shown in Figure 1 , so that the exhaust passage 31 is completely exposed to realize direct communication with the outside atmosphere.

[0045] Different recipes require different cooking environments, such as stewing, steaming or pressure cooking. The design of the exhaust valve in the present application enables the wok to adapt to multiple cooking methods. Specifically, the valve cover 2 in the present application is movably arranged on the valve seat 3, so that the valve cover 2 can move relative to the valve seat 3 to at least partially cover the exhaust passage 31 or completely open the exhaust passage 31, thereby facilitating the user to control the amount of steam discharged during cooking according to the cooking requirements, so that the wok in the present application can adapt to the needs of different cooking stages and different cooking foods for exhaust volume, provide more flexible cooking control, and improve the cooking taste of food. Moreover, by reasonably controlling the exhaust volume, energy loss can be reduced, cooking efficiency can be improved, and energy can be saved. Furthermore, during the cooking process, especially in a high-temperature and high-humidity environment, food and water vapor may overflow from the edge of the pot cover 1. By adjusting the state of the valve cover 2, the overflow can be effectively prevented, and the cooking environment can be kept clean. In addition, the valve cover 2 in the present application can be moved to a fully open state of the exhaust passage 31 to enable the pot cover 1 to quickly exhaust steam, so that the steam can be discharged in a short time, the pressure in the pot can be quickly released, and the accumulation of condensed water on the pot cover 1 can be reduced. For example, in the case of rapid stir-frying or rapid cooling, completely opening the exhaust passage 31 helps to improve the cooking efficiency.

[0046] The movable mode of the valve cover in the present application can adopt any one of the following embodiments:

[0047] Embodiment one: the valve cover is pivotally connected with the valve seat, and the valve cover rotates relative to the valve seat to switch between the covering state and the open state.

[0048] The present embodiment one realizes the state switching of the valve cover through the pivotal connection between the valve cover and the valve seat. During use, the user only needs to simply turn over the valve cover to realize the adjustment of the exhaust passage exhaust cross-sectional area, which is simple and convenient. Moreover, when rapid pressure or steam release is needed, the turning action of the valve cover can achieve rapid response and timely adjustment of the pressure in the pot. Furthermore, since the valve cover itself is provided with an exhaust hole, the valve cover itself has a relatively high temperature in the state of covering the valve seat during cooking. The pivotal connection mode can facilitate the user to control the turning of the valve cover by means of chopsticks, spoons and anti-scald gloves and other tools in the kitchen. In addition, in the present embodiment, the connection mode of the valve cover and the valve seat facilitates the user to thoroughly clean the exhaust passage and the inner surface of the valve cover by turning over the valve cover after cooking, avoiding dirt accumulation, and the pivotal connection between the valve cover and the valve seat can avoid the loss of the valve cover after cleaning.

[0049] In the present embodiment one, the rotating mode of the valve cover can adopt any one of the following embodiments:

[0050] Embodiment 1: as Figure 3 and Figure 4As shown, the exhaust valve further comprises a vertical shaft 4 arranged at one of the valve seat 3 and the valve cover 2, and a rotating hole arranged at the other of the valve seat 3 and the valve cover 2, and the valve cover 2 swings around the vertical shaft 4 to switch between the covering state and the uncovering state.

[0051] In this embodiment 1, the valve seat 3 and the valve cover 2 are rotationally connected through the vertical shaft 4, and when the valve cover 2 is rotated, the rotation angle of the user's wrist is small, which improves the comfort of operation, and in the case of high temperature, the user can directly push the valve cover 2 with common kitchen utensils such as chopsticks to realize the swinging of the valve cover 2, and the user's hands, wrists, etc. can not have to pass through the exhaust passage 31, which greatly reduces the risk of being scalded. Moreover, during the rotation of the valve cover 2 around the vertical shaft 4 to realize state switching, the valve cover 2 can have different covering areas for the exhaust passage 31 before the exhaust passage 31 is completely opened, which improves the diversity of exhaust volume adjustment, thereby better serving different cooking materials and improving the cooking effect.

[0052] As a preferred example under this embodiment 1, one of the valve seat 3 and the valve cover 2 is provided with a stop portion, and the other is provided with a limiting portion, and the stop portion and the limiting portion can abut along the rotation path of the valve cover 2 to limit the rotation angle of the valve cover 2. Through the stop cooperation of the stop portion and the limiting portion, the rotation angle of the valve cover 2 can be limited to avoid 360° rotation around the vertical shaft 4, so that the user can rotate the valve cover 2 to the initial state of covering the valve seat 3 without special attention, thereby improving the user experience.

[0053] For example, the stop portion is a first protruding column arranged on the valve cover 2, and the limiting portion is a second protruding column arranged on the valve seat 3, and in the process of rotating the valve cover 2 around the vertical shaft 4, the first protruding column and the second protruding column can abut along the rotation path of the valve cover 2 to limit the excessive rotation of the valve cover 2. For example, as shown in the accompanying drawings, Figure 4 As shown, the stop portion is a recessed portion 25 arranged on the valve cover 2, and the limiting portion is a protruding portion 32 arranged on the valve seat 3, and when the valve cover 2 is rotated around the vertical shaft 4 to the protruding portion 32 abutting into the recessed portion 25, the rotation is blocked, and the user can obviously feel the rotation resistance, so that the user can clearly know that the valve cover 2 has been rotated in place. Of course, it can also be reversed, and the stop portion is a protruding portion 32 arranged on the valve cover 2, and the limiting portion is a recessed portion 25 arranged on the valve seat 3.

[0054] As a preferred example under this embodiment, as shown in the accompanying drawings, Figure 5As shown, the valve seat 3 is provided with a sealing element 5, the valve cover 2 is provided with an abutting portion 26, the sealing element 5 is provided with an outer sealing lip 51 and an inner sealing lip 52, a sealing groove 53 with a top opening is formed between the outer sealing lip 51 and the inner sealing lip 52, and the abutting portion 26 abuts and seals with the sealing groove 53. Of course, it can also be reversed, that is, a protruding abutting portion is provided on the valve seat, a sealing element is provided on the valve cover, and a sealing groove with a bottom opening is formed between the outer sealing lip and the inner sealing lip, and the abutting portion abuts and seals with the sealing groove.

[0055] In the technical solution, the sealing element 5 is additionally arranged on one of the valve seat 3 and the valve cover 2, and the abutting portion is additionally arranged on the other one, so that the valve seat 3 and the valve cover 2 abut and seal in the initial state. On the one hand, it can avoid the steam, oil fume and the like in the cooking process from overflowing through the joint position of the valve seat 3 and the valve cover 2, thereby increasing the cleaning difficulty of the joint position of the valve seat 3 and the valve cover 2. On the other hand, the valve cover 2 can be kept in a fixed position, such as a position not working relative to the valve seat 3, or a position swinging to a certain angle relative to the valve seat 3 and not completely opening the exhaust passage, through the frictional resistance between the sealing element 5 and the abutting portion 26 in the cooking process, so as to avoid the valve cover 2 from freely swinging under the pushing action of the steam and the fume, and to ensure that the valve cover 2 can be kept in the position required by the user. In addition, there may be a situation that the user needs to open the pot cover to observe the internal cooking state in the cooking process. Through the frictional resistance between the sealing element 5 and the abutting portion 26, the position of the valve cover 2 can be fixed, so as to avoid the valve cover 2 from swinging under the action of the self-weight and causing the overflow of the condensed water and the like.

[0056] The fixing mode between the valve seat 3 and the sealing element 5 is not limited in the example, and preferably, the top of the valve seat 3 is provided with a mounting groove, and one end of the sealing element 5 is embedded into the mounting groove.

[0057] Embodiment 2: The embodiment 2 is not shown in the figure. In the embodiment 2, the exhaust valve further comprises a horizontal shaft arranged on one of the valve seat and the valve cover, and a rotating hole arranged on the other one of the valve seat and the valve cover, and the valve cover swings around the horizontal shaft to switch between the covering state and the uncovering state.

[0058] In the embodiment 2, the valve seat and the valve cover are rotationally connected through the horizontal shaft. In the case that the space of the pot cover is limited, the valve cover rotates around the horizontal shaft to realize the state switching, so that the valve cover does not interfere with other components (such as the handle and the visual window on the pot cover) on the pot cover in the rotating process, the upper space of the pot cover can be used to realize the state switching of the valve cover, which is convenient, fast and easy to operate.

[0059] As a preferred example under the present embodiment 2, the valve cover has a hinged end pivotally connected with the valve seat, and a free end away from the hinged end, the valve cover is provided with a latch at the free end, and the valve seat is provided with a buckle, when the valve cover is not needed to be rotated, the free end of the valve cover is fixed to the buckle of the valve seat by the latch to avoid the valve cover being lifted up by steam during cooking to cause heat loss.

[0060] Embodiment two: the present embodiment two is not shown, in the present embodiment two, the valve cover is detachably connected with the valve seat, and the valve cover can be taken off relative to the valve seat to switch between the covering state and the uncovering state.

[0061] In the present technical solution, the detachable connection between the valve cover and the valve seat facilitates the user to detach the valve cover to thoroughly clean the valve cover and the valve seat, so that the cleaning and maintenance work becomes easier, which helps to maintain the long-term performance and hygiene standard of the exhaust valve. Moreover, the detachable mode can avoid the space limitation of the pot cover itself during the state switching process, which avoids hindering the state switching, so that the exhaust valve in the present application can be applied to more types of pot covers.

[0062] As one of the embodiments of the present embodiment two, one of the valve cover and the valve seat is provided with an internal thread, and the other is provided with an external thread matched with the internal thread, and the valve cover is screwed to the valve seat.

[0063] As another embodiment under the present embodiment two, one of the valve cover and the valve seat is provided with a magnetic part, and the other is provided with a matching part matched with the magnetic part in magnetic attraction, and the valve cover is magnetically fixed to the valve seat by the magnetic force of the magnetic part and the matching part.

[0064] As still another embodiment under the present embodiment two, one of the valve cover and the valve seat is provided with a buckle, and the other is provided with a buckle position matched with the buckle, and the valve cover is fixed to the valve seat by the clamping cooperation of the buckle and the buckle position.

[0065] The specific structure of the valve cover in the present application can adopt any one of the following embodiments:

[0066] Embodiment three: the valve cover includes a cover body and an exhaust part connected with the cover body, the exhaust hole is arranged in the exhaust part, and the top of the exhaust part is flush with the top of the cover body, so that the upper surface of the valve cover is a plane structure.

[0067] Embodiment four: as shown in Figure 3 and Figure 4 The valve cover 2 includes a cover body 21 and an exhaust part 22 connected with the cover body 21, the exhaust hole 23 is arranged in the exhaust part 22, and the top of the exhaust part 22 is sunken relative to the top of the cover body 21, so as to form a liquid collecting groove 24 by the cooperation of the exhaust part 22 and the cover body 21.

[0068] In this fourth embodiment, the exhaust portion 22 is sunken relative to the top of the cover body 21, so that a liquid collecting groove 24 can be formed between the exhaust portion 22 and the cover body 21. The condensed liquid generated by the condensed steam can be accumulated in the liquid collecting groove 24, which reduces the probability of the liquid flowing out of the valve cover 2 to the rest of the pot cover 1, reduces the contaminated area, and thus reduces the cleaning burden of the user. In addition, the sunken exhaust portion 22 can increase the length and complexity of the exhaust path when the steam is exhausted, thereby reducing the flow speed of the steam and reducing the exhaust noise, thereby improving the user experience.

[0069] In addition, the exhaust portion 22 is sunken relative to the top of the cover body 21, so that a liquid collecting groove 24 can be formed between the exhaust portion 22 and the cover body 21. The condensed liquid generated by the condensed steam can be accumulated in the liquid collecting groove 24, which reduces the probability of the liquid flowing out of the valve cover 2 to the rest of the pot cover 1, reduces the contaminated area, and thus reduces the cleaning burden of the user. In addition, the sunken exhaust portion 22 can increase the length and complexity of the exhaust path when the steam is exhausted, thereby reducing the flow speed of the steam and reducing the exhaust noise, thereby improving the user experience.

[0070] As a preferred embodiment of the fourth embodiment, as shown in Figure 4 The exhaust portion 22 is raised upward to form a drainage surface 221 on the inner and outer surfaces of the exhaust portion 22.

[0071] In this embodiment, the exhaust portion 22 is raised upward, which can increase the structural strength of the valve cover 2 to a certain extent, avoid deformation under external force and high-temperature cooking environment, prolong the service life of the valve cover 2, and improve the stability and reliability of the valve cover 2. The drainage surface 221 formed on the outer surface of the valve cover 2 by the upward protrusion of the exhaust portion 22 can drain the condensed water to the edge of the liquid collecting groove 24, avoiding the condensed water from blocking the exhaust hole 23 of the valve cover 2, and ensuring the exhaust efficiency. The drainage surface 221 formed on the inner surface of the valve cover 2 by the upward protrusion of the exhaust portion 22 can break the bubbles of the soup and bubbles during cooking, thereby reducing the probability of the soup overflowing and reducing the cleaning burden of the user.

[0072] Further, the exhaust passage 31 has an air inlet end communicating with the cooking cavity of the pot body and an air outlet end communicating with the exhaust hole 23. The air outlet end of the exhaust passage 31 is an expanding structure with an increasing inner diameter from bottom to top, so that the air outlet end of the exhaust passage 31 can more easily receive the backflow of liquid and food, avoiding the exhaust hole 23 from being blocked.

[0073] In one embodiment, the liquid collecting groove has an equal diameter structure with equal inner diameters from top to bottom.

[0074] As a preferred embodiment of the fourth embodiment, as shown in Figure 4 The inner diameter of the liquid collecting groove 24 increases from bottom to top to form an expanding structure. In this embodiment, the liquid collecting groove 24 has an expanding structure with an increasing inner diameter from bottom to top, which can facilitate the user to clean the liquid collecting groove 24 and avoid dead cleaning angles.

[0075] As a preferred embodiment of the present application, the valve cover 2 is provided with a plurality of exhaust holes 23.
