Description
Technical Field
[0001] This utility model belongs to the technical field of tea brewing machine accessories, specifically relating to a constant temperature water outlet valve structure for a tea brewing machine. Background Technology
[0002] Driven by both consumption upgrades and the revival of tea culture, the tea brewing machine market has experienced explosive growth. A tea brewing machine is a device specifically designed for brewing tea, integrating functions such as boiling water, brewing, and heat preservation, making tea brewing simpler, more convenient, and more intelligent.
[0003] However, as the water outlet component of a tea maker, the traditional tea maker's water outlet valve usually only has a simple water outlet function and cannot maintain a constant water temperature according to usage needs. Although there are water outlet valves with constant temperature functions on the market, they usually use the thermal expansion and contraction of a thermosensitive element to achieve the water temperature. Because the sensitivity of the thermosensitive element may decrease or become inaccurate after long-term use, the water temperature cannot be maintained at a constant temperature for a long time, causing a lot of trouble for users. To address this issue, the applicant proposes a thermostatic water outlet valve structure for tea makers to solve the above problems. Utility Model Content

[0029] Example 1:
[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a thermostatic water outlet valve structure for a tea maker includes:
[0031] The tea brewing machine body 4 and the valve body mechanism 1 assembled on the tea brewing machine body 4, as well as the adjustment mechanism 2 assembled on the valve body mechanism 1 and the locking mechanism 3 assembled in the adjustment mechanism 2;
[0032] The valve body mechanism 1 includes a housing 11 fixedly installed inside the tea brewing machine body 4. The housing 11 has a water outlet chamber 15, a cold water chamber 17 and a hot water chamber 110 respectively. The cold water chamber 17 and the water outlet chamber 15 are connected through a cold water outlet 18, and the hot water chamber 110 and the water outlet chamber 15 are connected through a hot water outlet 111.
[0033] The adjustment mechanism 2 includes a threaded rod 24 rotatably installed between the cold water chamber 17 and the hot water chamber 110. A stop block 25 is threadedly connected to the outer periphery of the threaded rod 24. The stop block 25 is slidably installed between the cold water chamber 17 and the hot water chamber 110. One end of the threaded rod 24 extends out of the tea maker body 4 and is fixedly installed with a throttle 21.
[0034] As can be seen from the above, when in use, by connecting the cold water and hot water supply positions of the built-in cold water and hot water pipes of the tea brewing machine body 4, the cold water in the tea brewing machine body 4 can be introduced into the cold water chamber 17, and the hot water can be introduced into the hot water chamber 110. By turning the handle 21, the threaded rod 24 can be rotated. Utilizing the threaded engagement between the threaded rod 24 and the stop block 25, the rotation of the threaded rod 24 can drive the stop block 25 to move horizontally, so that the stop block 25 can block the cold water outlet 18 and the hot water outlet 111, which can conveniently adjust the opening and closing degree of the cold water outlet 18 and the hot water outlet 111, and can accurately control the mixing ratio of cold water and hot water.
[0035] When cold and hot water are introduced into the outlet chamber 15, they can be mixed to achieve the desired temperature. The outlet water temperature can be precisely controlled manually according to usage needs, without the need for a thermal element. This allows the outlet water temperature to be maintained at the required constant temperature for a long time, effectively improving the temperature control effect and bringing more convenience to the user.
[0036] Depend on Figure 6 It is known that the locking mechanism 3 includes a button seat 31 that is slidably installed inside the throttle 21 and a toothed ring 34 that is fixedly installed on one side of the tea maker body 4. A locking bracket 33 that engages with the toothed ring 34 is fixedly installed on one side of the button seat 31.
[0037] As can be seen from the above, by engaging the locking bracket 33 with the toothed ring 34, the throttle handle 21 can be easily locked, preventing it from being easily rotated and effectively avoiding accidental operation. By pressing the button seat 31 and moving it into the throttle handle 21, the locking bracket 33 can be moved synchronously, allowing the locking bracket 33 to separate from the toothed ring 34, thus releasing the lock on the throttle handle 21 and enabling it to rotate normally. This facilitates the movement of the adjustment block 25 to control the mixing ratio of cold and hot water, improving the performance.
[0038] For details, please refer to Figure 6 As shown, the inside of the throttle 21 is provided with a movable groove 26 for sliding the button seat 31 and the locking bracket 33. A return spring 32 is fixedly installed between the button seat 31 and the movable groove 26.
[0039] As can be seen from the above, the movable groove 26 allows the button base 31 and the locking frame 33 to move horizontally. Utilizing the elasticity of the return spring 32, the button base 31 can be pushed outward, which allows the locking frame 33 to engage in the tooth groove on the inner wall of the toothed ring 34, making it convenient to lock the throttle 21.
[0040] For details, please refer to Figure 3 As shown, the rear end of the housing 11 is connected to a cold water connection pipe 19 corresponding to the cold water chamber 17, and the rear end of the housing 11 is connected to a hot water connection pipe 112 corresponding to the hot water chamber 110.
[0041] As can be seen from the above, the cold water connection pipe 19 can be easily connected to the cold water inlet built into the tea brewing machine body 4, so that cold water can be introduced into the cold water chamber 17. The hot water connection pipe 112 can be easily connected to the hot water inlet built into the tea brewing machine body 4, so that hot water can be introduced into the hot water chamber 110.
[0042] Example 2:
[0043] refer to Figure 3As shown, the front end of the housing 11 is connected to a water outlet pipe 13 corresponding to the water outlet chamber 15, and a switch valve 14 is provided on the water outlet pipe 13.
[0044] As can be seen from the above, by opening the switch valve 14, the water in the water outlet chamber 15 can be easily discharged through the water outlet pipe 13, making it convenient to use a container to receive it for drinking.
[0045] refer to Figure 4 As shown, baffles 16 are fixedly installed on the inner wall of the water outlet chamber 15, and the baffles 16 are arranged in an alternating pattern.
[0046] As can be seen from the above, when cold water and hot water enter the outlet chamber 15, the baffle 16 can make the cold water and hot water flow in a serpentine direction, which can facilitate the rapid and thorough mixing of cold water and hot water and make the water temperature evenly distributed.
[0047] refer to Figure 3 and Figure 5 As shown, anti-slip strips 22 are distributed around the throttle 21, and temperature value scale lines 23 are engraved on the surface of the throttle 21. A pointer 12 corresponding to the temperature value scale lines 23 is fixedly installed on one side of the housing 11.
[0048] As can be seen from the above, the anti-slip strip 22 can increase the friction between the hand and the handle 21, making it less likely to slip when the handle 21 is rotated. By observing the value on the temperature scale line 23 corresponding to the pointer 12, the rotation position of the handle 21 can be easily controlled, the stop block 25 can be moved to the corresponding distance, and the opening and closing size of the cold water outlet 18 and the hot water outlet 111 can be precisely controlled, so as to achieve the required constant temperature by mixing cold water and hot water.
[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
