[0030] The following is a combination of the embodiments of the present invention Figure 1-6 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0031] like Figure 1-2As shown, a faucet device capable of switching between hot and cold is proposed, comprising:
[0032] Main structure with fixed settings;
[0033] The water outlet faucet pipe 5 is plugged into the main structure, and a hot water pipe 6 is passed through it. The space between the hot water pipe 6 and the water outlet faucet pipe 5 constitutes a cold water channel 5a.
[0034] A cold water delivery pipeline connected to the cold water channel 5a, in which a cold water delivery pump 18 and a cold water valve 19 are provided;
[0035] A hot water delivery pipeline connected to the hot water pipe 6, wherein a hot water delivery pump 16 and a hot water valve 17 are provided in the hot water delivery pipeline;
[0036] The electronic control module 15, such as Figure 6 As shown, it is equipped with a first circuit board 10 and a second circuit board 11 mounted on the main structure. The first circuit board 10 and the second circuit board 11 are respectively provided with a cold water switch 9a and a hot water switch 9b (collectively referred to as the water outlet switch 9, which are micro switches, as shown in FIG. Figure 2 As shown), the cold water switch 9a and the hot water switch 9b are electrically connected to the electronic control module 15. The cold water switch 9a is used to control the cold water delivery pump 18 and the cold water valve 19, and the hot water switch 9b is used to control the hot water delivery pump 16 and the hot water valve 17;
[0037] The keypad 1 (key part) has a certain elasticity, such as Figure 3-5 As shown, it is fixedly connected to the main structure and has a water pipe through-hole 1d for accommodating the water outlet faucet pipe 5. The keypad 1 has two pressing areas 1b and an opening hole 1a separating the two pressing areas 1b. The two pressing areas 1b are respectively located directly above the cold water switch 9a and the hot water switch 9b, and are respectively used to trigger the cold water switch 9a and the hot water switch 9b. The opening hole 1a is in the shape of a slit, one end of the opening hole 1a is an open structure, and the other end is close to the water pipe through-hole 1d. Controlling the distance between the opening hole 1a and the water pipe through-hole 1d can control the deformability of the two pressing areas 1b. The smaller the distance, the easier it is for the pressing area 1b to deform. On the contrary, the larger the distance, the less likely it is for the pressing area 1b to deform. Generally, the distance between the opening hole 1a and the water pipe through-hole 1d can be set to 5-10mm (reference size).
[0038] Therefore, the structure of the keypad 1 in this embodiment is relatively special, which is equivalent to cutting a slit between the two pressing areas 1b, and retaining a part to prevent the two pressing areas 1b from being completely separated. During the finger pressing process, the pressing area 1b will produce a corresponding downward deformation to press the corresponding switch. After the finger is released, the pressing area 1b is driven to reset upward by relying on the elasticity of the keypad 1 itself.
[0039] Among them, Figure 2As shown, the main structure is divided into an outer tube shell 4 and an inner fixing seat 2 fixed inside the outer tube shell 4. The outer tube shell 4 is made of a stainless steel tube, and the inner fixing seat 2 is made of plastic.
[0040] To facilitate installation, the upper side of the outer tube shell 4 is open, with the upper side of the inner fixing base 2 close to the upper side of the outer tube shell 4. The keypad 1 is fixedly connected to the upper side of the inner fixing base 2 and is located on the upper side of the outer tube shell 4, also covering the upper side of the outer tube shell 4. The inner fixing base 2 is provided with an internal through hole 2a extending vertically therethrough. A water guide base 3 is mounted on the bottom of the inner fixing base 2, a portion of which is fixedly inserted into the internal through hole 2a. The water guide base 3 is provided with a cold water hole 3a extending vertically therethrough. The cold water hole 3a communicates with the cold water channel 5a of the water outlet faucet pipe 5 through the internal through hole 2a. The hot water pipe 6 passes through the cold water hole 3a and is fixedly connected to the water guide base 3.
[0041] The cold water connector 8 and the hot water connector 7 are plugged into the bottom of the water inlet seat 3; the cold water connector 8 is connected to the cold water hole 3a and is used to connect the cold water delivery pipeline. The cold water delivery pump 18 and the cold water valve 19 are both located on the cold water delivery pipeline below the cold water connector 8; the hot water connector 7 is directly fixedly connected to the hot water pipe 6 and is connected to each other.
[0042] The first circuit board 10 and the second circuit board 11 are mounted on the upper side of the inner fixing seat 2 and are respectively located directly below the two pressing areas 1 b of the keypad 1 .
[0043] like Figure 4 As shown, the first circuit board 10 and the second circuit board 11 are respectively provided with a plurality of cold water display lights 12 and a plurality of hot water display lights 13, and the cold water display lights 12 and the hot water display lights 13 can display different colors; the cold water display lights 12 are electrically connected to the electronic control module 15 and light up when the cold water switch 9a is in a triggered state, and the cold water delivery pump 18 and the cold water valve 19 are simultaneously turned on to supply cold water; the hot water display lights 13 are electrically connected to the electronic control module 15 and light up when the hot water switch 9b is in a triggered state, and the hot water delivery pump 16 and the hot water valve 17 are simultaneously turned on to supply hot water.
[0044] Based on the previous solution, the keypad 1 is made of a transparent material or a translucent material so as to clearly display the triggering status of the cold water / hot water function.
[0045] like Figure 4 As shown, a light-isolating plate 14 made of an opaque material is fixed on the upper side of the inner fixing seat 2. The light-isolating plate 14 is located between the first circuit board 10 and the second circuit board 11 and directly below the opening 1a. The light-isolating plate 14 does not interfere with the downward deformation of the pressing area 1b. The light-isolating plate 14 can properly separate the distribution area of the cold water display light 12 and the distribution area of the hot water display light 13 to clearly define the luminous area where the cold water display light 12 and the luminous area where the hot water display light 13 are located.
[0046] In order to facilitate the installation of the first circuit board 10 and the second circuit board 11, the upper side of the above-mentioned inner fixing seat 2 is provided with a first placement groove 2b and a second placement groove 2c, and the first circuit board 10 and the second circuit board 11 are respectively installed in the first placement groove 2b and the second placement groove 2c; the cold water switch 9a extends upward beyond the first placement groove 2b, and the hot water switch 9b extends upward beyond the second placement groove 2c, thereby facilitating the triggering of the cold water switch 9a and the hot water switch 9b.
[0047] like Figure 1 、 5 As shown, a reinforcing rib 1e is integrally provided on the lower surface of the keypad 1 near the opening hole 1a and at the edge of the water pipe through hole 1d. Considering that the structural strength of the keypad 1 will decrease after the opening hole 1a is opened, in order to ensure the structural strength of the part between the opening hole 1a and the water pipe through hole 1d, the reinforcing rib 1e is provided to prevent breakage, and at the same time, the two pressing areas 1b can be deformed smoothly when pressed to trigger the switch below.
[0048] As a preferred connection method of the keypad 1, Figure 2 As shown, the lower plate surface of the key panel 1 is integrally provided with a lower locking plate 1f extending downward, and the side wall of the inner fixing seat 2 has a lower locking surface 2d connected to its upper side. The lower locking plate 1f is detachably attached to the lower locking surface 2d through fasteners.
